Suitcase harness and suitcase

The invention relates to suitcase crockery, in particular a multifunctional suitcase crockery for dimensionally stable hand luggage trolleys, as well as a suitcase with integrated crockery, in particular a dimensionally stable hand luggage roller suitcase with integrated multifunctional crockery.

In order to implement the Paris climate protection goals, incentives to replace private transport in favor of public passenger transport will have to be offered in the future. Particularly in the area of ​​rail-bound transport, the relevant mobility service providers are requested to keep track of the number of customers with high-frequency connections between the individual regional conurbations or regions. Metropolitan regions and, especially for people in rural areas, to significantly expand regional connections and access to the long-distance transport network.

However, the resulting problems can already be estimated from the current conditions. In particular, in the future:<ul id="ul0001" list-style="bullet"><li>the trains are at least partially so busy that there will not be enough seats available for all passengers,</li><li>the waiting areas will also be overcrowded, so that only an insufficient number of seats will be available here, and</li><li>the so-called "last mile" at the beginning and end of a journey, both in metropolitan areas and in rural areas, has to be covered increasingly by rental bicycles, e-scooters and other small forms of transport for so-called micromobility.</li></ul>

Suitcases in particular are used to store and transport the necessary luggage when traveling. These are available in different versions and sizes, whereby in most cases a hand luggage case (typical external dimensions maximum 55 x 40 x 20 cm³) is used. Hard-shell suitcases, in particular, are preferred travel companions because of their high stability and robustness and because of their better protection against rain and moisture.

Travelers with such suitcases are currently unable to use them as (emergency) seats in the train or in waiting areas, or only very inconveniently, and because of the inadequate mounting options, they cannot use rental bicycles or e-scooters to cover the "last mile". In addition, with wheeled suitcases used as seating, the problem often arises that they do not have any brakes and can therefore perform jerky movements in the approaching or braking train. In addition, when sitting on the suitcase, the mountings of the rollers are heavily loaded by the additional weight of the person sitting, which can lead to increased wear and tear and premature material fatigue.

From the <patcit id="pcit0001" dnum="DE102006051765B4"><text>DE 10 2006 051 765 B4</text></patcit> a backpack with a frame and a cover is known, which can be carried on the back and can also be used as a seat due to a stable outer frame. Backpacks that can be converted into trolleys are from the<patcit id="pcit0002" dnum="US6592012B2"><text>US 6,592,012 B2</text></patcit> as well as the <patcit id="pcit0003" dnum="WO03096838A1"><text>WO 03/096838 A1</text></patcit> known. However, none of the three carrying systems mentioned are suitable for use with conventional suitcases. In addition, these carrying systems only offer an emergency seat option, if at all, which offers little comfort for longer sitting and lingering, for example in the corridor of overcrowded trains.

From the <patcit id="pcit0004" dnum="DE202016004333U1"><text>DE 20 2016 004 333 U1</text></patcit> a rolling baggage cover with a backpack function is known, which is, however, not suitable as a seat due to a flexible sheathing. A suitcase, which includes a fold-out emergency seat, can<patcit id="pcit0005" dnum="EP1402797A1"><text>EP 1 402 797 A1</text></patcit> can be removed. However, this emergency seat is only intended for smaller children and is not suitable for larger loads from adults. Incidentally, this seat is integrated into the corresponding case and is not suitable for use with conventional cases. In the pamphlets<patcit id="pcit0006" dnum="US20090289480A1"><text>US 2009/0289480 A1</text></patcit>, <patcit id="pcit0007" dnum="US20040021353A1"><text>US 2004/0021353 A1</text></patcit> and <patcit id="pcit0008" dnum="EP3113647B1"><text>EP 3 113 647 B1</text></patcit> systems compatible with conventional suitcases are disclosed, but these are also only suitable as an emergency seat for children. However, all of the mentioned emergency seat systems lack a corresponding carrying option for use with typical small means of transport.

The invention is based on the object of overcoming or at least reducing the problems of the prior art and of providing a solution for the "last mile" transport difficulties that occur when traveling with previous travel and hand luggage suitcases. The object according to the invention is achieved by means of a suitcase harness and a suitcase with integrated crockery according to the independent claims. Preferred further developments are the subject of the respective back-referenced subclaims.

The invention relates to a suitcase harness for attachment to a suitcase of a specified maximum size, comprising a length-adjustable first belt strap which is provided for enclosing the case along its opening edge, the first belt strap having two transversely protruding shoulder strap holders along its longitudinal axis, which are provided for this purpose , to be carried out below a handle on the short handle side of the case to the nearest cover half of the case; two length-adjustable second belt straps, which are used to enclose the case perpendicular to the longitudinal direction of the first belt strap in each case at a position in the first and last third of the case (preferably in a position in the first and last quarter of the case, particularly preferably approximately in the first and last quarter of the case or at the level of any case locks) are provided, wherein the second belt straps can be guided through double straps integrated into the first belt strap at the points of intersection with the first belt strap; and a padding plate, designed to be able to at least partially cover the short handle side of the case without a lateral protrusion, the padding plate having a depression on at least one side, in which the handle on the short handle side or a handle on a long handle side when using the upholstery plate as a base for sitting on these sides can be completely accommodated and which is intended to accommodate dishes for storing the suitcase dishes, the upholstery plate through the second Belt straps can be fixed to one half of the lid. The padding plate can have a depression or a continuous opening in the form of a hole on both sides.

The suitcase harness is used as a belt system which is designed to be attached to a suitcase and can serve as a fastening and / or transport aid. The term suitcase crockery is also intended to include other accessories which are intended to be attached to the crockery or which are directly related to the use of the suitcase crockery according to the invention.

A suitcase can in particular be a typical foldable travel or hand luggage suitcase in the form of a cuboid. It is preferably a case in which rollers (also referred to as wheels) are attached to at least one side (wheeled case). The case can preferably be a dimensionally stable hard-shell case or a so-called half-shell case. Such cases are typically characterized by the fact that these two lid halves (an upper and a lower lid half), a short handle side with a first handle (usually opposite to the side with the rollers), and a long handle side with a second handle (usually opposite to the side along which it is opened), with suitcase locks possibly located on the long handle side on both sides of the second handle.

On the side of the case opposite the long handle side there are mostly rotatable joints (hinges) for opening the case. The opening can, however, also be implemented without joints via an area adjoining the opening edge which is otherwise designed for folding the case halves, for example a flexible connection of the case halves in this area. The opening edge is the area where the two halves of the cover of the case meet when they are closed. The case can be closed, for example, by means of a zipper that extends at least in sections along the opening edge or by means of case locks.

The length-adjustable belt straps can be, for example, lashing straps, fixed straps or flexible straps. The belt straps should be adaptable to different suitcase sizes (e.g. by other suitcase models or manufacturers) and, in particular, enable additional accessories to be attached by clamping, lashing, or the like. The straps should be able to be wrapped around the various axes of the case so that they can be grasped. While the first belt strap is intended to surround the case along its opening edge, the two second belt straps should be able to surround the case perpendicular to its opening edge.

The first strap has along its longitudinal axis two transversely protruding shoulder strap holders, which are provided to be passed underneath a handle on the short handle side of the case to the nearest cover half of the case. The shoulder strap holders are arranged at such a distance from one another that they can be passed through the handle opening as parallel as possible. A short strap section is referred to as a shoulder strap holder, which at its free end offers a buckle, eyelet or other fastening option provided for connection to an optional shoulder strap.

The first belt strap furthermore has a plurality of double straps along its longitudinal axis for the passage of the second belt straps. A double strap denotes in particular a strap section which is designed in two layers and in which the layers are firmly connected to one another at the respective section ends in such a way that a flat eyelet for the passage of a second strap results. However, the double flap can also be constructed differently, for example by using several or different layers. The inside of a double flap is preferably friction-reinforced on one or both sides. This can be done, for example, by gumming or roughening the respective surfaces. By increasing the friction, the connection between the second belt straps guided through the double straps and the first belt strap can be improved.

The length-adjustable second belt straps have the particular task of preventing the first belt strap from slipping and of fixing it to the case. For this purpose, the second belt straps can be reinforced with friction at the points where they are passed through the double straps of the first belt strap. Such a friction reinforcement can preferably interact with a friction reinforcement on one or both sides on the inside of a double flap of the first belt strap. Instead of a friction reinforcement, the respective surfaces can also be designed as corresponding elements of a Velcro strip. The case can be protected against accidental opening by means of the second belt straps attached to the case. The second belt straps can also be attached individually to the case without using the first belt strap. Another function of the straps is that the padding plate can be attached to the case. Fastening can take place, for example, by clamping the padding plate between the two second belt straps and the case.

The second belt straps preferably each have a section with a padding plate belt, the padding plate straps being suitable for fastening the padding plate to the suitcase harness. The upholstery plate belts can be designed in such a way that they each form a double flap over said section along the second belt straps. The double flap can preferably be opened by a buckle or some other type of closure. Such an embodiment with an additional upholstery plate belt has the advantage that the second belt straps placed on a case do not need to be loosened for fastening the upholstery plate and they can thus continue to firmly enclose the case. A section located on the second belt straps with an additional upholstery plate strap enables the upholstery plate to be attached to the second belt straps by means of the double straps, independently of the attachment of the second belt straps to a suitcase. The length of the upholstery plate belts is preferably adjustable.

The position and the length of the double flap section on the second belt straps are preferably set in such a way that the double flap should extend along the top of one case half. This means that the upholstery plate can be completely fixed on this side. A buckle or some other lock should preferably be positioned in such a way that it does not rest on the side of the fixed padding plate facing away from the case. This enables the upholstery plate to be used as a cushion even when it is attached to the case. Preferably, after the suitcase harness has been put on, the double strap section of the second belt straps extends through the associated double straps of the first strap.

A preferably right-angled plate made of a compressible soft material, which is suitable as a comfortable seat pad or as a back pad, is referred to as a cushion plate. This can in particular be a foam, for example made of polyurethane (PU), polyethylene (PE) or silicone.

The upholstery plate has a depression (in the sense of a spatial recess) at least on one side. If the upholstery plate is used as a seat pad, the handle on the short handle side or a handle on a long handle side can be completely accommodated in the recess in this recess. The handles do not interfere with sitting and the upholstery plate can be stably placed on the respective side of the case. Furthermore, individual (preferably all) suitcase crockery parts can be inserted into the recess for storing the suitcase crockery, so that the necessary packing size for the suitcase crockery can be limited to the outer dimensions of the padding plate. While the belt straps are attached to the case, the padding plate can be fixed to one of the lid halves for storage using the second belt straps. The fixing of the upholstery plate can be improved in that the edge areas of the upholstery plate, at which the second belt straps are bent around the upholstery plate during fixing, are designed to be tapered. The width of the padding plate is slightly smaller at these waists, so that the padding plate can be effectively prevented from slipping out of the second belt straps.

In order to prevent the upholstery plate from slipping when it is used as a seat, the inside of the recess can be provided with a rubber coating. With this rubber coating, the upholstery plate can be fixed above a handle by means of increased friction. The padding plate is preferably gummed in the area around the depression on the surface of the padding plate containing the depression.

Due to the different external dimensions of a case, it basically offers three possible seat heights. While sitting on the case shells seems impractical due to the low seat height and stability, the remaining two sides offer the option of using the case on the one hand as a "high stool", especially in areas where there are many people, for example on platforms, and on the other To be used as a "low stool", especially in areas where people sit predominantly, for example on trains. The latter position is also suitable for working with a laptop or the like, as it can be conveniently placed on the knees of the person sitting. The conversion is carried out by placing the suitcase and placing the padding on the side of the suitcase pointing upwards.

The upholstery plate can preferably comprise, at least in sections, an inner core made of a rigid material, for example a hardboard or wood board. The core can increase the stability and robustness of the padding. The depression in the cushion plate can preferably extend down to the core material, this then forming the bottom of the depression. This results in the insertion of the suitcase crockery parts into the recess opposite a fixed support and the padding plate is protected from damage by the inserted suitcase crockery parts. To fix the inserted suitcase crockery parts, the exposed core at the bottom of the recess can preferably have fastening means, for example rubber bands, straps or clamps, which enable the inserted suitcase crockery parts to be fastened within the recess. As a result, they cannot fall out when storing or transporting the upholstery plate or the suitcase harness. To protect the upholstery plate, it can comprise a (preferably washable or replaceable) cover.

The cushion plate is preferably designed as an inflatable or self-inflating cushion. The upholstery cushion can preferably consist of a foldable plastic material. To increase comfort, the surface can be covered with a soft, velor-like material. A self-inflating upholstery cushion can be constructed in such a way that it can be compressed strongly under pressure, but when it is relaxed it returns to its original volume while absorbing air from the surroundings. In particular, a self-inflating cushion can comprise a foam material or mechanical springs or spring cores in its interior. Preferably, the cushion can be fixed to one half of the cover by means of Velcro fasteners. An inflatable or self-inflating cushion as a cushion plate can simply be folded or rolled up when not in use. As a result, it takes up less space than a rigid pad. It can also be used as a flexible pad independently of the case. Furthermore, weight can be saved by such an upholstery cushion. As a result, a fixation on the case by means of Velcro fasteners can be sufficient and use independent of the case is made easier.

In the inflated state, the upholstery cushion, analogous to the rigid upholstery plate described above, also has a recess on at least one side in which a handle on the short handle side or a handle on the long handle side can be completely received on these sides when the upholstery plate is used as a seat pad. In addition, this recess is provided for receiving items of crockery for storing the crockery. For example, corresponding holding elements can be arranged within the recess. The holding elements can be, for example, integrated belts, pockets, tabs and straps, but also air-filled clamping elements extruded by the inflation. Crockery items to be packaged when not in use can be placed in the indentation area even when the cushion is not inflated, and the cushion can be rolled up or folded around it. The non-inflated cushion can be used as a packing bag for the dishes.

Preferably, the suitcase harness further comprises two shoulder straps, which can be attached to the two vertically protruding shoulder strap holders on a short handle side of the case and to the first strap on the side of the case opposite the shoulder strap holders, the attached shoulder straps allowing the case to be carried with one half of the lid allow the back of a person and the padding can be used as a back pad. The upholstery plate can be fixed to a cover half by the second belt straps, this also corresponds to the preferred storage position of the upholstery plate. The shoulder straps can also have padding for the shoulders of the wearer, at least in sections. To fasten the shoulder strap holder on the opposite side of the case to the first belt strap, like the shoulder strap holder, the latter can each offer a buckle, eyelet or other fastening option provided for connection to the shoulder strap.

The case can be carried on the back like a rucksack, hands-free. This enables, in particular, the use of typical small means of transport, such as rental bicycles or e-scooters, as a feeder to a main means of transport. Due to the arrangement of the shoulder strap holders and their implementation below a handle, the forces arising from the use of a rucksack can be optimally absorbed and deflected via the case handle holder. Otherwise, these forces would pull the dishes down from the case. The shoulder strap holders are attached to the first belt strap in such a way that the harness is warped or deformed as little as possible when the case is carried as a backpack. The shoulder straps can also be easily removed to roll a trolley case. The case can therefore be rolled smoothly.

One idea of ​​the invention is thus that, taking into account the maximum permitted load weight, each travel or hand luggage case can be converted into a comfortable seat or, for example, to use a rental bike or an e-scooter, as a backpack. With the rucksack option, the padding plate, which is normally used as a seat cushion, can then be used as a back pad, which enables the case to be carried comfortably. Other uses as a backpack, such as B. to overcome height differences through many steps in train stations and airports, or on unpaved surfaces, are obvious. The suitcase harness thus offers a simple way of converting conventional suitcases into a multifunctional suitcase backpack or a seat with at least two different heights in just a few steps.

The suitcase harness preferably further comprises a light that can be fastened to the belt straps. This can in particular be a red rear light which, when the case is carried as a backpack, can increase its rear visibility in the dark. The light can preferably be attached to one of the second belt straps. Fastening can take place, for example, using Velcro strips, hooks located on the light, or on pockets attached to the belt, as well as using another conventional type of fastening.

The color of the first and the two second belt straps is preferably different to avoid confusion when the harness is placed on the case. This enables the suitcase harness to be put on quickly and easily even under difficult conditions, for example after the start of the journey on a crowded platform or on a train.

Preferably, the suitcase harness further comprises a roller protection in the form of a frame, with one roller side of the suitcase being able to be set up in the frame placed on the floor so that the rollers are relieved and the suitcase is held stable by the frame. The roller protection makes the rollers virtually float, so that when the case is used as a "high stool", ie If you sit on the opposite side of the suitcase from the wheels, the suitcase wheels are protected from damage due to excessive weight. To store the roll protector, it can be placed in the recess of the pad when not in use. The dimensions of the recess preferably correspond to the outer dimensions of the frame, so that it can be largely positively fixed in the recess. The frame is preferably designed in such a way that there is still enough space inside the recess to fully accommodate the remaining suitcase crockery accessories. The crockery and in particular the roller protector can thus be stored and transported without any problems when the suitcase crockery is not in use.

The roller guard can be provided with buffers, for example made of rubber, on its upper side. The buffers can protect the outside of the case from damage by the frame of the roller guard. Depending on the arrangement of the buffers, they can also be adapted to a specific case profile and thereby enable the support area of ​​the frame to be optimally adapted to the shape of the case. Preferably, the frame has a plurality of feet on its underside, for example made of rubber, as a floor pad. These enable the case to stand firmly even on problematic surfaces (e.g. gravel, paving stones, sensitive parquet or laminate).

The suitcase harness preferably further comprises at least one third belt strap, which is provided to stabilize the first belt strap on the underside of the case and can be attached to a second strap. In particular, the third belt strap can already be firmly connected to the first belt strap at the appropriate point, so that the third belt strap, for example, can only be wound or looped around the closer second belt strap on the left and right and then fixed accordingly. A fixation can take place, for example, by means of a Velcro fastener or a clamp buckle. The third belt strap can, however, also be connected to the first belt strap via a double strap integrated into one of the two strap straps at the appropriate point. Two third belt straps are preferably used to stabilize the first belt strap. With additional stabilization, the lateral forces that act on the first strap when carrying the back can be absorbed. Furthermore, the stabilization prevents the first belt strap from being pinched or dragged on the rollers and from dragging on the floor.

Another aspect of the invention relates to a case with an integrated crockery, comprising two lid halves, a short handle side and a long handle side, with two first areas on a first area facing the long handle side and two first areas opposite the first area along a lid half Has fastening means; two belt straps, which are provided for fastening to a first fastening means each of the first area and the second area; and a padding plate, designed to be able to at least partially cover the short handle side of the case without a lateral protrusion, wherein the padding plate can be fixed to the first lid half by the two straps. The padding plate can have a depression or a continuous opening in the form of a hole on both sides. In particular, the first area facing the long handle side and the second area opposite the first area along a lid half can be located on a common first lid half of the case. Depending on the shape of the case or its edges, all or individual areas can, however, also be located completely or partially on the long handle side and the side opposite the long handle side.

The terms short handle side and long handle side were chosen to distinguish them from the opposite sides. In particular, the short handle side, which can also be referred to as the short top side, is opposite the short bottom side of the case. The long side of the handle, which can also be referred to as the long front, is opposite the long back of the case. The handle sides are the preferred locations for attaching handles, but the actual presence of handles is not important.

A suitcase according to the invention largely corresponds to the case types already mentioned for the suitcase dishes according to the invention, so reference is made to the corresponding parts of the description. Reference is also made to the corresponding sections of the preceding description of the suitcase harness according to the invention for the structure and function of the padding plate. In the case of the harness for the case according to the invention, belt straps comprising the case can be dispensed with, since this has several fastening means with which parts of the harness can be connected directly.

In particular, the case has two first fastening means on a first area facing the long handle side and on a second area opposite the first area along a lid half, by means of which the two belt straps can be tensioned along one lid half. The belt straps can be, for example, lashing straps, fixed straps or flexible straps. The belt straps are preferably adjustable in length. The belt straps should enable additional accessories to be attached by clamping, lashing or similar.

The upholstery plate preferably has a recess on at least one side in which a handle on the short handle side or a handle on the long handle side can be completely received on these sides when the upholstery plate is used as a seat pad and which is intended to accommodate crockery items for storing the crockery is.

The case preferably comprises two second fastening means in each case, which are arranged on a third area facing the short handle side and on a fourth area opposite the third area along a lid half; and two shoulder straps which can be attached to the two second attachment means of the third area and to the second attachment means of the fourth area, the attached shoulder straps allowing the case with one lid half to be carried on the back of a person and the padding plate being used as a back pad can. In particular, the third area facing the short handle side and the fourth area opposite the third area along a lid half can be located on a common first lid half of the case. Depending on the shape of the case or its edges, all or individual areas can, however, also be located completely or partially on the short handle side and the side opposite the short handle side.

The shoulder straps correspond to the shoulder straps already described for the suitcase harness according to the invention, so reference is made in this regard to the corresponding parts of the description. The suitcase can also be converted into a suitcase backpack with little effort. The upholstery plate attached to the lid half can also be used here as a back cushion. The essential difference to the case harness according to the invention, however, is that the further straps for fixing to the case can be dispensed with, which simplifies the effort for the retrofitting. The shoulder straps can also be removed again when not in use and inserted into the recess of the upholstery plate if necessary.

The fastening means are preferably eyelets, retractable belt holders in the case frame or retaining pins sunk in the case frame. Different types of fastening means can be combined in a case, for example first fastening means can be designed as eyelets and second fastening means as retractable belt holders or exactly the other way around. Pin-shaped fastening means, which are provided, for example, for connection to carabiners or hooks, are referred to as retaining pins. Countersinking can take place, for example, in that the retaining pins are arranged in a depression (or depression) on one side of the case structure or in a depression in an edge of the case structure.

Retractable belt holders can for example include eyelets, retaining pins, rings, clamping buckles or the like, these being arranged on the case in such a way that they can be sunk into or on the surface of the case. Sinking can take place, for example, in a pocket, flap or compartment. However, it is preferably countersunk in such a way that the belt holder can be accommodated in a recess on one side of the case structure or in a recess in an edge of the case structure. Sinking can be done either manually by simply pushing in or inserting or automatically using a corresponding pull-in device. In particular, such a retraction device for retraction can comprise a spring mechanism or a stretchable rubber cord. If the belt holder is not required, it is automatically lowered by a corresponding retraction force. A recessed or retractable arrangement of the fastening means has the advantage that they cannot interfere with the case when not in use and that one cannot get stuck with or on them.

Another aspect of the invention relates to a case with integrated dishes, comprising lid halves, a short handle side, and a long handle side; two belt tensioners each, which are arranged on a third area facing the short handle side and on a fourth area opposite the third area along a cover half; an upholstery plate, designed to be able to at least partially cover the short handle side of the case without a lateral overhang, the upholstery plate having a recess at least on one side in which a handle on the short handle side or a handle on the long handle side when the upholstery plate is used as a seat pad can be fully included on these pages; and two shoulder straps which are connected to the two belt tensioners of the third area and to the belt tensioners of the fourth area, the shoulder straps allowing the case with one lid half to be carried on the back of a person and the padding plate can be used as a back pad. In particular, the third area facing the short handle side and the fourth area opposite the third area along a lid half can be located on a common first lid half of the case. Depending on the shape of the case or its edges, all or individual areas can, however, also be located completely or partially on the short handle side and the side opposite the short handle side.

The terms short handle side and long handle side were chosen to distinguish them from the opposite sides. In particular, the short handle side, which can also be referred to as the short top side, is opposite the short bottom side of the case. The long side of the handle, which can also be referred to as the long front, is opposite the long back of the case. The handle sides are the preferred locations for attaching handles, but the actual presence of handles is not important.

This case also largely corresponds to the case types already mentioned for the case crockery according to the invention, so reference is made to the corresponding parts of the description. Reference is also made to the corresponding sections of the preceding description of the suitcase harness according to the invention for the structure and function of the padding plate. In the case of the harness for the case according to the invention, belt straps comprising the case can be dispensed with, since this has two shoulder straps as integrated harness, which are connected to belt tensioners arranged on the case. When retracted, the shoulder straps can be used to attach the padding to the case. Another advantage of this embodiment of a case according to the invention is that the shoulder straps do not have to be removed or otherwise stowed when not in use.

The belt tensioners can in particular be roller belt tensioners with automatic retraction (similar to a seat belt in a car). Manual locking of the length of the protruding belt strap can be provided. The belt tensioners can also be designed in such a way that the belt webbing is only rolled up in the state where there is no tension. Another possibility is manual actuation of the belt tensioner. In addition to manually pulling in or rolling up the webbing, tightening can take place when the case is put on, for example using additional tightening straps or another means of actuating the tightening function. In this case, tightening can be carried out using a ratchet (similar to lashing straps for securing loads).

The paragraphs below apply to both of the above-mentioned embodiments of suitcases according to the invention.

The case preferably also comprises rollers (or wheels) on one side of the case, which are arranged in such a way that they can be retracted into the case frame when the case is loaded above a specified maximum load, so that the case rests with the roller side on the floor . This retraction can take place, for example, in that the rollers are attached to the case via suitable spring elements, the spring force of which is coordinated in such a way that they yield above a maximum permissible weight load to such an extent that the associated side of the case rests on the floor and the rollers are therefore not overloaded. A typical maximum weight for the load on the rollers is around 40 kilograms. The rollers can also be retracted manually, for example. In this case, before the case is used as a seat, the position of the castors can be locked.

The case preferably has a large number of feet, for example made of rubber, as a floor support on the side with the rollers. These enable the case to stand firmly even on problematic surfaces (e.g. gravel, paving stones, sensitive parquet or laminate). Alternatively, the feet can also each be designed as an element of a housing for the rollers. Since the additional attachment of the feet to the case is thus not necessary, the manufacture of the case is simplified in particular. No additional holes need to be drilled in the case to attach the feet and no additional feet need be taken into account when designing the case. In addition, feet integrated into the roller housing can be designed to be more stable.

The cushion plate for a suitcase according to the invention is preferably designed as an inflatable or self-inflating cushion. The upholstery cushion can preferably consist of a foldable plastic material. To increase comfort, the surface can be covered with a soft, velor-like material. A self-inflating upholstery cushion can be constructed in such a way that it can be compressed strongly under pressure, but when it is relaxed it returns to its original volume while absorbing air from the surroundings. In particular, a self-inflating cushion can comprise a foam material or mechanical springs or spring cores in its interior. Preferably, the cushion can be fixed to one half of the cover by means of Velcro fasteners. An inflatable or self-inflating cushion as a cushion plate can simply be folded or rolled up when not in use. As a result, it takes up less space than a rigid pad. It can also be used as a flexible pad independently of the case. Furthermore, weight can be saved by such an upholstery cushion. As a result, a fixation on the case by means of Velcro fasteners can be sufficient and use independent of the case is made easier.

Analogous to the upholstery plate described above, the upholstered cushion can also have a depression on at least one side in which a handle on the short handle side or a handle on the long handle side can be completely received on these sides when the upholstery plate is used as a seat pad. In addition, this recess can also be provided to accommodate crockery items for storing crockery. For example, corresponding holding elements can be arranged within the recess. The holding elements can be, for example, integrated belts, pockets, tabs and straps, but also air-filled clamping elements extruded by the inflation. Any crockery items to be packaged when not in use can also be placed in the indentation area when the cushion is not inflated and the cushion can be wound or folded around it. The non-inflated cushion can be used as a packing bag for the dishes.

Further preferred refinements of the invention result from the features mentioned in the subclaims.
