Furniture device with adjustable firmness

[0001] The invention relates to a furniture device, such as a bed or mattress, a seat cushion or the like adapted to absorb human weight. A device having a holding unit and at least one section comprising a base to be supported by a substrate of a movable plate member which is connected to the base by a moving mechanism and at least one elastic device. The plate element is configured to cooperate with at least one elastic device and to move as a result of the action of the moving mechanism relative to the base to adjust the hardness of the elastic device and thus also the section. The spring device comprises a pocket made of fabric and a spring member which is located in said pocket. The pocket is attached to adjacent pockets via fabric. The attachment between two adjacent pockets is formed so that the elastic devices can move independently of each other along the distance measured from the free end of the elastic device and perpendicular to the plate element. The holding unit includes a connecting part and a holding member that is connected to the at least one spring device through the connecting part. The connecting parts are arranged on a straight line that runs through the center of two or more attached elastic members.

BACKGROUND OF THE INVENTION [0002] A furniture device, such as a bed or mattress, a seat cushion or other, is configured to respond to a weight or part of a person's weight, such device distributing a person's weight over a portion of the surface of the furniture device. Depending on how the device distributes the weight of a person, it will be soft or hard. The degree of hardness of such a furniture device depends on the properties of the elastic element, such as, for example, spring constant or air pressure. Another parameter that affects the degree of hardness is the position of the elastic element or elements in the furniture appliance; the pre-tensioned coil spring is harder than the free coil spring, the same applies to an airbag that is compressed;

is harder than a loose airbag. In this way, the hardness of a furniture device, such as mattress , is usually determined during production.

[0003] In known furniture devices having properties according to the field of the invention, the hardness of the device can be adjusted by deforming the elastic members, i.e. by pretensioning them. A mechanism comprising a deformation member that is capable of deforming the elastic members is used to adjust the hardness of the device or mattress. The hardness of such furniture devices can be adjusted by the user, even after the device has been manufactured. The hardness of the elastic members can be adjusted even after the furniture has been used for some time, which compensates for any changes in their properties.

[0004] Contemporary furniture devices with the above-described properties often include elastic members with a so-called pocket spring design, in which each elastic member comprises a resilient element and an elastic shell that surrounds the spring such that the spring is positioned in an elastic shell. Such pocket spring designs allow each spring to be deformed separately without affecting adjacent springs. However, known spring mattresses cannot be combined with mechanisms that allow the spring hardness to be adjusted without losing the ability to deform without affecting adjacent springs.

[0005] Document WO2005 / 053466 describes an upholstered unit, such as for example a bed or mattress, comprising a plurality of pocket springs and at least one inflatable member located above and / or below at least several pocket springs. Document WO2005 / 053466 describes the use of an inner pocket spring disposed inside an outer pocket spring, whereby these pocket springs can be placed on an inflatable member. Building an upholstered unit according to this description is complicated, heavy and due to many inflatable members, also prone to failure.

[0006] Document EP2245967 A1 describes a furniture device adapted to absorb human weight, comprising a section with a base, a plate member and a set of elastic members. The elastic members are connected to the base via a connection system, a mesh member and connecting members, and they are mounted on a plate member. The plate member is located above the base, relative to the ground, and can be moved through the deforming member, thereby tensioning the elastic members. The elastic members comprise an elastic element and an elastic sheath seating the elastic element. The connecting members are attached to the mesh members, and the mesh member is connected to the connection system. The mesh member is a rigid mesh element. The use of the mesh member increases the complexity of manufacturing, building and weighting of the furniture device. In addition, when the weight of a person affects the device, it can affect adjacent areas of the same section or adjacent device sections via the mesh member, because the mesh member is preferably a rigid mesh.

OBJECT AND SUMMARY OF THE INVENTION [0007] It is an object of the present invention to provide an improved furniture device that allows adjustment of hardness.

[0008] Furthermore, it is an object to provide such a furniture device in which the deformation caused by the weight of the user acting on one elastic device of the furniture device does not affect adjacent elastic devices.

[0009] Another object is to provide such a furniture device in which the hardness of the elastic devices can be easily adjusted with a high degree of accuracy.

[0010] Still another object is to provide such a furniture device that is easy to use, comparatively light and easy to manufacture.

[0011] Another object of the present invention is to provide an economical furniture device.

[0012] Another object of the present invention is to provide a sensitive furniture device in use.

[0013] These objects are obtained by a furniture device according to claim 1. [0014] The furniture device described herein configured to absorb human weight has a holding system and at least one section comprising a base, a movable plate member, a moving mechanism and at least one resilient device. The plate element is configured to cooperate with at least one elastic device and to move as a result of the movement mechanism relative to the base to adjust the hardness of the at least one elastic device.

The elastic device comprises a fabric pocket and an elastic member, the elastic member being located in the pocket. The pocket is attached to adjacent pockets, the attachment being formed so that adjacent spring devices can move independently of each other along a first distance, measured from the free end of the spring device and in a direction perpendicular to the plate member. The holding assembly comprises a connecting part and a holding member which is attached to the base or plate element and is connected to the at least one spring device via the connecting piece, so that at least one spring piece is suitably compressed and loosened over the entire length during the movement of the plate element up and down. The connecting parts are arranged in a straight line that runs through the center of two or more attached spring devices. The holding member is an elastic thread or string that is directly connected to each connecting part.

[0015] The connection of the holding members with the connecting parts has the advantage that no additional element is needed for this. This facilitates the production and reduces the weight of the bed.

In addition, it also increases sensitivity and reduces the impact on adjacent sections and individual elastic devices when human weight affects a section or part of a section of a furniture device.

[0016] Furthermore, the arrangement of the connecting part and the holding member such that the entire length of the elastic device depends on the movement of the plate element, increases the accuracy by which the hardness of the furniture device can be adjusted. As defined in claim 1, the holding member can be connected to the base.

[0017] The holding member may pass through the recesses in the plate member. The plate element can be located above the base relative to the ground. The holding member can be attached, as defined in claim 1, to the base and / or connecting parts and / or the plate element via knots at two ends and pass through the base, the plate element and the connecting parts between the two ends in a wavy manner. The plate member can be moved by the moving mechanism away from the base and the ground, such that the holding members hold the elastic device in its original position, so that the plate element pretension the elastic devices during displacement. As defined in claim 1, the holding member can be connected to the plate element.

[0018] In such an embodiment, the elastic devices can be placed on the base and the plate element below the base relative to the ground. The holding member can pass through the recesses in the base and can be attached to the plate element at two ends and pass in a wave-like manner through the plate element, the base and the connecting parts between them. It is also possible to attach the ends to the connecting parts or base. The plate element can be configured to move from the base towards the ground by means of a moving mechanism for pre-tensioning spring devices. In this case, the moving mechanism works only against the elastic force of the elastic device. Multiple holding members can be arranged in one section. They can also be arranged in many directions on a plate member or base. Preferably, the spring members are helical springs, and the connecting parts can be arranged in a straight line that extends through the center of the helical springs.

[0019] Coil springs can be made of metal or alternatively plastic. Coil springs have good elastic properties and are easy to obtain and install.

[0020] In a preferred embodiment, the spring device may have a length, measured perpendicular to the plate member, such that the first distance is greater than or equal to 1/15 of the length and less than or equal to 2/3 of the length. Thanks to this, adjacent elastic devices can move independently of each other and if the weight of a person acts on a furniture device or part of it, it does not affect the neighbor. As defined in claim 1, the holding member can be a string that connects a plurality of connecting parts. Twine or thread, or the like, is flexible, soft and easy to handle and install. The string can be made of cotton or synthetic material. In another embodiment, the connecting portions may be pocket transitions, welded and glued seams. It is possible to combine different types of connecting parts in one section. It is possible to use welded seams in one horizontal direction and glued seams in another direction. It is also possible to provide recesses, cut-outs or through holes in the pockets and to guide the holding member through these recesses, for example around the edges of the section.

The use of different types of joining parts has advantages during the manufacture of a furniture device and can also be advantageous with respect to the durability of a furniture device. In the case where one piece of fabric is used to make multiple pockets, the weld seams can be fixed during the manufacture of the pocket, namely when the fabric is welded together to form a pocket.

In another embodiment, the connecting parts are formed directly on the elastic member. In this embodiment, the holding members can be attached directly to the elastic members. Such direct fastening can be beneficial for the durability of the furniture device, as it can reduce the consumption of pockets.

[0021] In a preferred embodiment, the elastic device comprises more than one elastic member and respectively more than one pocket, the elastic member and the respective pocket are stacked on top of each other.

[0022] This increases the sensitivity of the furniture device and allows the user to adjust the hardness in a certain way and within a certain range.

[0023] It is advantageous if the pockets are welded together in one horizontal direction and glued together in another horizontal direction.

[0024] When using different fastening methods between pockets, it can be advantageous when the rows of elastic devices are connected to each other. As described above, it is possible to use one fabric to seat more than one elastic member, thus forming a row of elastic devices, and thus the pockets can be joined together by welding in one direction and by gluing in the other direction.

[0025] It is preferred that the furniture device can be a bed or mattress 10 comprising a plurality of sections.

[0026] Such a bed or mattress can have an advantage if it is to be used by different users, such as in hotels. Another application can be the treatment of patients with back or hip problems, because the individual sections allow the mattress to harden, for example in the buttock and shoulder area, to straighten the back and hips, thus enabling the mattress to be adapted for each patient.

[0027] In another embodiment, the pockets are attached to adjacent pockets in such a way that they are not connected to each other along a distance measured from the plate element in a direction perpendicular to the plate element and where the distance is greater than or equal to 1/15 of the length of the spring device. The pockets are therefore generally attached only to the adjacent pocket in the area of ​​the central section.

[0028] As a result, the hardness adjustment of one section does not affect the adjacent section, especially in the case where one section contains only one elastic device.

[0029] In an embodiment, each section may comprise a single spring device.

[0030] This allows the user to adjust the section hardness very accurately. In a preferred embodiment, a set of 6 x 13 spring devices is positioned in the section.

[0032] It is obvious to a person skilled in the art that such a size or arrangement depends on the width and length of the bed or mattress, or the furniture device in general. The section may also have a different layout, for example the whole mattress may consist of one section. It is clear that any other systems are included within the scope of the present invention.

[0033] It is preferred that the holding member passes from one connecting part through the plate element to the base where it is attached to the base and back through the plate element to another connecting part and so on.

[0034] In this case, the holding member may preferably be a string. This interwoven system has the advantage that its production is comparatively easy and efficient.

[0035] In general, all terms used in the claims should be interpreted in their normal sense in the technical field, unless expressly stated otherwise in this document. All references to "element, device, component, center, stage, etc." shall be interpreted clearly as referring to at least one element, device, component, center, stage, etc., unless expressly stated otherwise. The steps of each method described here do not have to be carried out exactly in the order described, unless explicitly stated otherwise.

DETAILED DESCRIPTION [0037] The invention will now be described in more detail with reference to the attached figures, which show some embodiments of the invention.

This invention, however, can be made in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are given by way of example to make the present description accurate and complete and to fully disclose the scope of the invention to those skilled in the art. The relevant numbers refer to similar items throughout the description.

[0038] Figs. 1a to 5b show section 30 and the holding unit 20 according to an embodiment of the invention. Section 30 may be part of a furniture device, such as a bed-mattress, sofa or other upholstered furniture device. Section 30 of the furniture device comprises a base 2, a movable plate element 4, a moving mechanism 6 and at least one elastic device 12 as illustrated in Figs. 1a to 5b. The movable plate element 4 carries and seats a plurality of spring devices 12.

The number of elastic devices 12 per section 30 can vary from 1 to a large number, e.g. 400 elastic devices 12 or even more. The figures show an embodiment with 5x3 (and thus 15) spring devices 12 per section and an embodiment with one spring device 12 per section (Fig. 5a and 5b). Section 30 is configured to accept the weight of a man. The human weight generates a force F, schematically indicated in Fig. 1a to 1d and fig. 5a. FIG. 5a schematically shows how forces with different values ​​F0, F1, F2, F3, F4, F5 and F6 affect elastic devices 12. F0 is zero, which shows the elastic device 12 at rest. The elastic devices 12 can be attached to the plate element 4 or placed freely and held only by the holding unit 20 on the plate element 4. The holding assembly 20 is configured to hold the elastic devices 12 in place and thus it is not necessary to attach the elastic devices 12 to the plate element 4.

The holding assembly 20 comprises a holding member 22 and a connecting portion 24, as best seen in Fig. 2 up to 4. The holding assembly 20 holds each elastic device 12 in position and limits the vertical movement of the upper part of the elastic device 12 when the plate element 4 is moved or moved in a direction perpendicular to the base 2, as shown in Fig. 1b, 1d. When the plate element 4 is moved or displaced relative to the base 2, then the elastic devices 12 are pre-stressed. Moving the plate element 4 allows you to adjust and change the hardness of section 30. The offset plate element 4 as shown in fig. 1b and 1d, causes the hardness to be higher than when the plate element 4 is not moved, and therefore when it is in its original position. The spring devices 12 comprise a pocket 14 and a spring member 18 embedded in the pocket 14. The pocket 14 is made of a fabric such as cotton or preferably a synthetic fabric that can be welded by means of a suitable machine. The elastic member 18 is best illustrated in Fig. 1c, 1d and 5b. In the illustrated embodiment, the elastic member 18 is a helical spring 26, for example made of metal or plastic.

[0039] Pockets 14 can be attached to adjacent pockets 14 by welding or gluing, thus forming the attachment 32, 32 'as best seen in Fig. 3 and 4. In the embodiment shown, the pockets are welded together in one direction (Y) and glued together (X) in the other direction, as shown in Fig. 1c, 3 and 4. Within the scope of the invention, it is possible to use the same method for securing pockets 14 to each other in both directions. The attachment 32 between the two pockets 14 can be used to connect the holding member 22 to the spring device 12, but this is not necessary. It is possible to connect the holding member 22 to the spring device 12 independent of the fastening 32, as will be discussed below.

[0040] The connecting part 24 is formed either on the pocket 14 as shown in the figures or directly on the elastic member (not shown in the figures). In a later case, the connecting part should be formed in the highest part of the elastic member. Each spring device 12 may include one or more connecting parts 24. In the embodiment shown in the figures, each spring device 12 includes two connecting parts 24. In the case where the holding member 22 is connected to the spring member 18, one connecting portion 24 on the spring device 12 may be sufficient, especially when the holding member 22 is centrally connected to the spring member 18.

[0041] The connecting parts 24 of the section 30 are arranged so as to be positioned on a straight D which extends through the means Z of attached and adjacent spring devices 12, which is best illustrated in Fig. 2. Straight line D can be oriented in the horizontal direction Y, horizontal direction X or can be oriented diagonally. In the case where only one connecting part 24 is assigned to each elastic device 12 or in the case where multiple connecting parts 24 are arranged, the connecting parts 24 of adjacent spring devices 12 can always be arranged such that the line D runs through the centers of the spring devices also extending through the connecting parts 24 of adjacent connected elastic devices 12.

[0042] When the holding member 22 is connected directly to the spring member, it is theoretically possible to make section 30 without the pocket 14 and to create a connection between adjacent spring members 18, however since open helical springs can affect the fabric and destroy it in contact, for example with due to sharp edges, it is preferable to use pockets 14 to reduce wear on the furniture device.

[0043] The elastic member 18 is free to move inside the pocket 14 and its movement is limited only by the upper part of the pocket 14 in connection with the holding member 22. The elastic member 18 may have no lateral engagement, e.g. friction, such as in the case of pockets 14 or adjacent elastic devices 12. In the case where the holding member 22 is directly connected to the spring member 18, the movement of the spring member 18 is directly limited by the holding member 22.

[0044] The actuating mechanism 6 may comprise a rod 10 and a drive combination, wherein the drive may be an electric motor connected to the rod 10, for example via a belt or chain, or the like. The moving mechanism 6 may comprise more than one mandrel 10 so that the plate element 4 can be moved symmetrically. The drive or electric motor may include a user interface configured to control the movement of the plate element 4.

[0045] In the illustrated embodiments, the holding member 22 is a string or thread connected to the plurality of connecting parts 24. The holding members 22 may extend along the direction X and connect a plurality, in this case five, of elastic devices 12 through the connecting parts 24. It is possible to use additional holding members 22 extending in the Y direction, thereby obtaining holding members 22 in the X and Y direction. Alternatively, it is also possible to use only holding members 22 extending in the Y direction. The connecting part 24 may need to be positioned so that it is arranged on the D line that runs through the centers Z of the spring devices 12.

[0046] The holding member 22 is connected to the base 2 by the first end 36 and then guided up through the recess 34 in the plate element 4 to the connecting portion 24, down through the next recess 34 'to the base 2 and then up through the same recess 34 'to the next connecting part 24' and so on passing from one connecting part 24 to the next connecting part 24 'and so on, as best illustrated in fig. 1b, 1d and 2. The base 2 may include holes or vias (not shown) used to secure the holding member 22 to the base 2. The holding member 22 can be connected to the base 2 by a second end 38, as illustrated in fig. 1b. At the first 36 and second 38 ends, the holding member 22 can be rigidly attached to the base 2, which means that it cannot move along its longitudinal, while between the first and second ends 36, 38 the holding member 22 can be loosely attached to the base 2, which means that the holding member 22 is connected to the base 2 so that it can move along its longitudinal direction, for example by means of vias or the like. Alternatively, the holding member 22 may also be rigidly attached to the base 2 between the first and second ends 36, 38.

[0047] In the case where the connecting parts 24 are welded or glued, the holding member 22 may be guided around these welds or glues, as shown in the figures. In an alternative embodiment, the connecting portions 24 may include channels in the pocket 14, and the holding member 22 may be guided through said passages (not shown).

Different combinations of different types of joining parts 24 can be used in one single section 30. The type of joining part 24 may also depend on the design of section 30.

[0048] The attachment 32, 32 'between the pockets is best illustrated in Fig. 3 and 4. In the X direction, the pockets 14 may be attached to adjacent pockets 14 differently than in the Y direction. FIG. 3 illustrates the fastening 32 in the Y direction, this fastening 32 is performed by welding two layers of fabric together, and Fig. 4 illustrates the attachment 32 'in the X direction which is performed by gluing with glue or similar means. [0049] Turning now to Fig. 3, it can be seen that the fastening 32 is made in the middle of the spring device 12. Attachment 32 may include a grommet or the like to securely guide the holding member 22. To ensure proper operation of the furniture device, the spring devices 12 may not be attached to the adjacent spring devices 12 to the end, which means that the spring devices 12 are free and independent of the adjacent spring devices 12 in the upper end region that extends from the free end of the device elastic 12.

Each elastic device 12 can thus move freely and independently of the adjacent elastic devices 12 along the distance A measured from the free end of the elastic device 12 to the upper end of the attachment 32. In addition, each elastic device 12 can also move freely and independently of adjacent elastic devices 12 along the distance B measured from the plate element 4 towards the lower end of the attachment 32. Mount 32 shown in Fig. 3 is preferably a welded attachment 32, i.e. it is formed by welding the two layers of fabric used to form and manufacture the pocket 14. Holding the elastic device 12 without any attachment 32 along distance B ensures that the strength of two adjacent sections 30 of the furniture device can be adjusted independently of each other.

[0050] The distance A may be greater than or equal to 1/15 of the total length L of the elastic device 12 and less than or equal to 2/3 of the length L. The distance B may be greater than or equal to 1/15 of the total length L of the elastic device 12 and preferably less than or equal to 2/3 of the total length.

[0051] The distance C, measured from the free end of the spring device 12 to the upper end of the connecting part 24 indicates where the connecting part 24 is located, as shown in figure 3. C can be equal to or greater than zero and may not necessarily correspond to the distance

A, which is measured between the upper end of the fastening 32 and the free end of the elastic device 12. The holding member 22 can be connected to the elastic device 12 at a point or area that differs from the fastener 32, 32 '.

[0052] Fig. 4 shows the fastening 32 'in the X direction. This connection may be a glued fastening 32'. The distances A 'and B' correspond to the distances shown in Fig. 3, but they do not have to be the same, which means that the distance A between the upper end of the glued attachment 32 'and the free end of the spring device 12 and the distance A' between the upper end of the welded attachment 32 the free end may and most likely will be different. The same applies to distances B and B ';

distance B between the lower end of the heat-sealing attachment 32 and the plate element

4 and the distance B 'between the bottom end of the glued attachment 32' and the plate element 4 can be and most likely will be different. Both distances A and A 'should be equal to or greater than 1/15 and less than or equal to 2/3 of the length L of the spring device, and distances B and B' should be equal to or greater than 1/15 of the length L.

[0053] It should be noted that the smallest distance A and A 'defines the distance along which the elastic device 12 can be compressed independently of the adjacent elastic device 12 and thus without affecting the adjacent elastic devices 12 when the human body weight affects the furniture device. Furthermore, the smallest distance B and B 'determines how the displacement of the plate element 4 and the displacement of the plate element in the adjacent section can be different.

[0054] Figs. 3 and 4 show that the elastic devices 12, and thus the pockets 14 and elastic members 18, bulge in the middle. This may be advantageous when fixing the fasteners 32, 32 ', however, the elastic devices 12 may have the shape of a symmetrical cylinder or any other suitable shape, and thus without protuberances in the middle.

[0055] The welded attachment 32 may be formed during manufacture of the elastic device 12. As a result, a plurality of elastic members 18 can be placed on a comparatively large fabric, then the fabric can be folded on top of the elastic members 18 to cover them, and in the next step a welding machine or the like can be used to form weld seams between the elastic members 18 to close said elastic members 18 in pockets 14. The welder can be configured to additionally separate the pockets from each other where it is needed to determine the free distances A and B as described above. Then, many such welded rows of elastic devices 12 can be glued together to form a system of elastic devices 12, which system can be used and installed on section 30.

[0056] Fig. 5a and 5b show a section 30 with a plurality of spring devices 12 and an integrated section 30 "comprising a single spring device 12. The distance B, B '(not shown in figures 5a and 5b) should in this case preferably be greater than or at least equal to 1/15 of the length L of the spring device 12 to allow movement of the section 30' comprising a single spring device 12 independent of the section 30 containing many spring devices 12. The embodiment shown in fig. 5a and 5b may include a moving mechanism 6 comprising for example a gear mechanism or a plurality of drives so that section 30 'can be moved independently of section 30. The mandrel 10 can be used to move the section 30 'by the drive. The integrated section 30 'can also be a row or column consisting of a plurality of elastic devices 12. Section 30 may have any other shape. Integration of sections

30 'with another section 30 may have the advantage of regulating the hardness of the furniture device in various areas for specific needs.

[0057] Figs. 1c, 1d and 5b show how the elastic members 18 are compressed or pre-stretched in the pocket 14. For illustrative purposes, the pockets 14 are shown as transparent. The compressed elastic members 18 'have different properties than the uncompressed elastic members 18, as mentioned before the compressed elastic members

18 'are generally harder than the uncompressed spring members 18, and thus the user can adjust the hardness of the mattress by moving the plate element 4 of the sections 30, 30' by means of a user interface which is connected to the drive.

[0058] In an alternative embodiment (not shown), the plate element can be located below the base relative to the ground and can be configured to move towards the ground. In such an alternative embodiment, the resilient devices may be mounted on the base, and the base may comprise recesses through which the holding members may be guided for connection with the plate element in this case. In this solution, the plate element can move the holding members, which then tension the elastic devices, while the elastic devices are stationary and mounted on the base. In such an embodiment, the holding member can be connected to the plate element by the first end and then guided through the base to the connecting part and then back through the base to the plate element through the base to the next connecting part connecting the connecting part to the next connecting part and so on Such an embodiment of the section can advantageously be used in beds or mattresses comprising only one section, because the displacement of the plate element actually causes a change in the level or height of the upper surface of the section, and therefore the mattress. In addition, in this embodiment, the height of the top surface of the furniture device, e.g. a mattress, can be adjusted.

[0059] Section 30, 30 'can be installed on a bed mattress, in a sofa or in a special medical device or medical bed. The furniture device may comprise one or more than one section 30, and it is also possible to combine the described embodiment of section 30 with a conventional mattress so that the user can customize and modify his furniture device, even after purchasing it.

[0060] Furthermore, the embodiments shown in the figures comprise one layer of elastic devices 12 and section 30, however the section may comprise two or more layers of elastic devices 12, whereby the elastic devices 12 are attached to each other via their respective front sides, for example by bonding. In this embodiment, the elastic devices 12 are stacked on top of each other.

[0061] In another embodiment of the invention, the pocket may comprise two or more elastic members 18, stacked on top of each other, but still seated in the same pocket.

[0062] The furniture device is made in the form of a holding member 22 being a flexible thread or string.

[0063] The elastic thread or cord can be directly attached to the elastic member 18 via the connecting parts 24.

[0064] Alternatively, a flexible thread or string can be directly attached to the pocket 14 via the connecting parts 24.

[0065] The invention has mainly been described above with reference to several embodiments. However, as one skilled in the art will readily understand, other embodiments than those described above are equally possible within the scope of the invention as defined in the appended claims.
