Safety Device for a Piece of Luggage Comprising a First Outside Zipper and a Second Inside Zipper

Full description

Background of the invention

The invention relates to a means of security for a bag comprising a first outside zipper and a second inside zipper.

The invention is particularly useful for improving the security of bags equipped with zippers.

The invention applies to suitcases in general, suitcases, PC cases, a variety of containers, business accessories, bags, knapsacks, etc., which may or may not be equipped with wheels.

Bags with zippers offer insufficient protection against theft even when equipped with a lock. In fact, when the zippered bags cannot be seen by the owner and are being handled by carriers, the zippers can be opened by pressure from a pointed object or tip between the teeth of the zipper. Thus, the pressure used between the zipper teeth makes it possible to push the zipper teeth down, to separate and separate these teeth. After unscrewing several teeth, it is possible to open the zipper by pulling to extend the opening in a chain over the entire zipper, thus making it possible to open the travel bag or piece of luggage. This process, which is performed using moderate pressure, does not leave visible marks on the separated teeth. After examining the contents of the piece of luggage and optionally removing part of it, the operator re-closes the zipper using a back and forth motion, without leaving traces.

The first objective of the invention is to eliminate the known drawbacks of the prior art by proposing a new security device for a bag comprising a first outside zipper and a second inside zipper.

U.S. Patent Document No. 6,223,349-1B describes a sealing method for a wet covering, particularly one made of chloroprene rubber. Said closure device cannot constitute a security device for a bag due to the fact that the teeth of the outside zipper can be easily separated by external pressure from a pointed tool on the outside zipper. In addition, the closure device includes internal sealing layers and an intermediate seal which cannot be used on an item of luggage that requires periodic opening or closing.

US Patent Document No. 2,641,037 describes a hermetically sealed device comprising a first outside zipper and a second inside zipper. A locking device cannot constitute a safety device for a safety device due to the fact that the teeth of the first outside zipper are opened by the application of pressure from a pointed tool.

US Patent Document No. 0264815/2008-1a describes a weapons case that has a hard outer surface. The gun bag has an external zipper and bottom edges. A gun bag cannot be used as a piece of luggage with a safety device due to the fact that the individual zipper teeth do not withstand the separation force exerted by a pointed tool.

German patent document No. 19935380-1A describes a weather-resistant clothing zipper. This zipper cannot be used as a bag security device due to the fact that its teeth can be separated by a pointed tool.

US Patent Document No. 2,166,885 describes an airtight receptacle. Said airtight receptacle includes a zipper attached to a combination of two internal elastic sealing bands. This method cannot be used as a bag security device due to the fact that the zipper teeth can be dislodged by a pointed tip or tool.

US Patent Document No. 3,102,570 relates to a means of securing a zipper. The combination of sealing device and zippers does not make it possible to create a security device for a bag, due to the fact that the teeth of the outside zipper can be separated by a pointed tool and the sealing device can then be separated before opening the second zipper by separating the teeth with a pointed tool Pointed head.

US Patent Document No. 2,454,214 describes a closure device comprising two zippers and an intermediate securing device. This closure cannot be used as a bag security device due to the fact that the zipper teeth can be separated by a pointed tool.

US Patent Document No. 1,734,434 describes a means of closing openings that must be sealed against air, gas, and water. This closure cannot be used as a bag security device due to the fact that the teeth of the outside zipper can be separated by a pointed tip or tool.

The invention also aims to provide a means of security for a bag that includes a first outside zipper and a second inside zipper with economical production and easy practical use. The zippers of the bag must be actually easy to open and close and for this reason they cannot include thick teeth made of plastic. Syringes that open and close with difficulty and have a high break point.

The fasteners typically used for luggage are generally small-toothed closures, preferably made of polyamide (Nylon, brand), which open and close easily in a straight line, in corners and curves, with a very low breaking point.

In a third aspect, the invention provides an improved means of security for a bag equipped with a first outside zipper and a second inside zipper, the zippers having sizes and tooth characteristics approaching those normally used for luggage equipped with a single zipper.

General description of the invention

The present invention aims at a security device for a bag comprising a first outside zipper and a second inside zipper, characterized by the fact that the two zippers are installed directly close to each other, such that the teeth of the two zippers come into contact due to external pressure on the outside zipper using A pointed tool, by keeping the outer zipper of the jaw under the pressure of the pointed tool.

According to other alternative features of the invention:

Detailed description:

Referring to Figures 1 through 8, elements are optionally identical or equivalent with identical reference numbers.

In Figure 1, a first embodiment of the device according to the invention includes a first outside zipper 1 and a second inside zipper 2.

Zippers 1 and 2 are assembled at the edges3a, 3b of the cover of a piece of luggage not shown as a whole along assembly lines 4a, 4b.

The length of the curve defined by the midline of the outside zipper 1 between the nearby assembly lines, in this patent, 4a, 4b, is called the “free width” and is referred to by the reference number 1.

The length of the curve defined by the second inside zippermidline of the second inside zipper 2 and included along the nearby assembly lines is, in this patent, 4a, 4b, the “free width” and is referred to as the reference number l 2.

Each zipper 1 or 2 includes aligning pairs of cooperating teeth 1a or 2a, and two selvages 1b or 2b for assembling corresponding teeth 1a or 2a.

When a force is exerted on the teeth 1a of the outside zipper 1 using a P tip or a pointed tool, the two selvages 1b bend and the teeth 1a settle on the teeth of 2a the second inside zipper 2.

The strong support provided by the teeth 2a of the second inner zipper 2 keeps the teeth of the outer zipper 1 from loosening under the pressure of the pointed toolP and the tip P from getting between the teeth of 1a of the first outer zipper 1.

Protection against forced entry also results from the fact that the free width L1 of the first outside zipper 1 is the same as or greater than the free width L2 of the second inside zipper 2.

In the model shown in Figure 1, zippers1 and 2 are mainly superimposed on each other.

In Figure 2, a second embodiment of the device according to the invention includes elements identical to those described by reference to Figure 1.

In this model, zippers 1 and 2 are installed with offsetd protrusion.

The offsetd protrusion is chosen by the expert in the field so that the teeth 1a and 2a of zippers 1 and 2 come into contact when external pressure is applied to the outside zipper 1 using a P tip or a pointed tool.

The contact of the teeth of the 1a and 2a zippers 1 and 2 includes a rigid support that keeps the teeth of the outside zipper 1 from loosening under the pressure of the P end or the tapered tool.

The free width L1 of the first outside zipper 1 is the same as or greater than the free width L2 of the second inside zipper 2.

The invention also relates to unknown variables where the free width of the first outer zipper 1 approaches or is even slightly less than the free width of the second inner zipper 2, where the essential is that the teeth of the outer zipper 1 touch the teeth of the second inner zipper 2 when pressure is applied to the zipper External 1 with a pointed tip or tool.

3, a third embodiment of the means according to the invention includes zippers 1 and 2.

The two edges or selvages 1b and 2b are gathered in advance along lines 4 and 5 to place the first and second zippers 1 and 2, one after the other.

Assembly lines of 4 and 5 zippers can be placed on the outside or inside of the lines to attach to the cover of the luggage piece.

Clouds 1 and 2 can be controlled individually, each with its own slider, not shown.

In this example, the free width of the first outside zipper 1 is its centerline length between nearby assembly lines 4 and 5; The free width of the second inside zipper 2 is the length of its center line between the nearby assembly lines 4 and 5.

After initial placement of zippers 1 and 2 has been carried out by tying along assembly lines 4 and 5, preferably by sewing, zippers 1 and 2 are then attached to walls 6 and 7 of the bag piece along connection lines 8 and 9.

If assembly lines 4 and 5 of zippers are placed outside the lines for attaching to the cover of a luggage piece, the free width of the first outside zipper 1 is the length of its center line between the closest assembly lines 8 and 9; The free width of the second inner zipper 2 is the length of its center line between the proximal assembly lines 8 and 9.

When pressure is applied by the pointed toolP on the first outer fastener 1, the teeth 1a come into contact with the teeth 2a of the second inner fastener 2 and rest on the latter to withstand the penetration of the tip or pointed tool P and keep it from loosening.

In Figure 4, a fourth embodiment of the device according to the invention includes a first outside zipper 1 and a second inside zipper 2.

Each zipper 1 or 2 includes teeth 1a or 2a running together and edges or selvages 1b or 2b.

It is preferable to assemble the edges or selvages 1a of the first zipper 1 on the edges or selvages 2a of the second inner zipper 2 along positioning lines 4 and 5.

Assembly lines 4 and 5 for zippers may be located on the outside or inside of the bag piece shell, i.e. between pins 1a and 2a, on one side, and pins 1b and 2b, on the other side.

The assembly produced in this way is fitted to the edges3a, 3b of the cover of a solid piece of luggage by means of a protective lip 10a, 10b, preferably made of PVC (polyvinyl chloride).

In Fig. 5, a fifth embodiment of the device according to the invention includes a first outside zipper 1 with teeth 1a and selvages or edges 1b, and a second inside zipper 2 with teeth 2a and selvages or edges 2b.

It is preferable to place edges or selvages 1b and 2b and connect them to each other along positioning lines 4 and 5.

Along assembly lines 4 and 5 for zippers can be located on the outside or inside of the luggage item's cover fastening lines.

The assembly thus produced is mounted on a flexible wall 3a, 3b of a suitcase or flexible piece of luggage and also on the inside lining 11a, 11b of a suitcase or flexible piece of luggage.

Due to the resulting position of the assembly along lines 4 and 5, the force exerted by the pointed toolP or tip on the outside zipper teeth 1a brings the teeth 1a into contact with the support teeth 2a and keeps the teeth 1a from being forced out and separated by the tip or tool P.

The invention applies to all types of different bags, bags and containers which can be fitted with or without wheels and which can be rigid or flexible.

In Figure 6, a sixth embodiment of the device according to the invention is particularly useful in application to flexible or semi-rigid luggage.

The device includes a first outside zipper 1 having teeth 1a and edges or selvages 1b, and a second inside zipper 2 having teeth 2a and edges or selvages 2b.

It is preferable to place zippers 1 and 2 by assembly along two positioning lines 4 and 5 before assembling with the flexible fabric 3a, 3b to cover a flexible piece of luggage.

It is preferable to arrange the outside and inside zippers mainly 1 and 2, one above the other.

Engaging and disengaging teeth 1a, 2a, zippers 1 and 2 are controlled by the movement of a single slider means 13.

However, the invention also covers the case of two zippers having a small lateral offset d less than two widths of a zipper tooth.

It is preferable that the vertical space measured between the teeth of the outside and inside zippers be less than the thickness of one and a half teeth of the zipper.

Thanks to the single slider means 13, the outer closing means and the inner closing means are closed simultaneously. After the luggage portion is completely closed, a notched tip or tool P is not inserted between the teeth 1a, it is possible for the teeth 1a to be penetrated and loosened which could result in the suitcase or flexible luggage portion being forced open.

Therefore, locking and holding the teeth of 1A of the outside zipper with the support provided by the teeth of 2A of the inner zipper prevents the operator of the luggage or flexible luggage item from being forced open.

Accordingly, the invention makes it possible to place an internal support consisting of the inner zipper 2 directly under the outside zipper 1 and along its full length by keeping the pin 1a from the first outer zipper from penetrating and loosening.

The inner zipper 2 then provides a support structure that forms reinforcement and grip for the teeth of the outer zipper 1a.

The single slider means 13 includes a first recess that engages with the teeth of the outer zipper 1a and a second recess that engages with the teeth of the inner zipper 2a.

The single sliding means 13 preferably includes a separation between the two spaces mentioned above, and preferably an intermediate barrier 13a, the thickness of which is less than the thickness of the tooth 1a or 2a.

Thanks to the single sliding device 13, the operation of the outer zipper 1 and the operation of the inner zipper 2 are simultaneous.

This identical operation and cooperation of the special teeth 1A and 2A also enhances the efficiency of the position of the outside and inside zippers 1 and 2.

The use of a double-actuated central sliding device 13 makes it possible to reduce the space in a closed position between the teeth 1a and 2a, which also improves the resistance movement to the penetration of the end P, which is achieved by using support obtained by the teeth 2a of the inner zipper. In Fig. 7, the The single slider means producing the form of the two sliding means in the previous art installed one above the other with a single upper bridge 13b equipped with a small eyelet 13c designed to allow the insertion of a locking element such as a padlock.

Bridge 13B is configured to operate with a single pull eye, not shown. By operating the aforementioned single pull tab, the user opens or closes the two superimposed zippers by performing quick and easy hand movements identical to the movements made on an unsecured prior art luggage.

The invention may also apply to a device containing two zippers of different sizes. In this embodiment, not shown, in the case of a single central slider, the slider has a different shape on the upper half than on the lower half, such that the shapes are adapted to the different sizes of the zippers.

In Fig. 8, another single central sliding device 14 reproduces the appearance of two prior art sliding devices superimposed with a transversal offset d corresponding to a device of the type described by reference to Fig. 2, wherein zippers 1 and 2 are mounted on each other with a transversal overhang. offset d.

The invention applies to all variants of the method obtained using two sliding means of the prior art, superimposed with an offset protrusion, regardless of the direction of such protrusion. If the partial sliders are installed with a longitudinal overhang d, the single slider means corresponds to a device where two zippers of the same size are optionally installed with a longitudinal offset. If the partial sliders are installed with an inclined overhang, the single slider means formed in this way corresponds to a device in which the two zippers are mounted on each other with an overhang corresponding to the transverse component of this overhang on the incline.

The single slider means 14 of Figure 8 include a small locking hole 16 designed for the passage of a locking type element. The single slider means 14 in Figure 8 may also include two separation interfaces 15a, 15b if offsetd close to the width of the zipper tooth.

The invention described by reference to several embodiments is not limited in any case but, on the contrary, covers any modification of form and any changed embodiment within the scope and content of the invention.

The invention also applies to a means obtained using two halves of a sliding means of different shapes. In this embodiment, not shown, the sliding device has a different half-sliding device shape on the left half than on the right half for configuration according to the different fasteners or has different shapes for each of the two halves of the sliding device.

The invention also applies to a means obtained by using two halves of a sliding means comprising separation barriers of protruding teeth. In this embodiment, not shown, the sliding device has a different separator shape on the upper half than on the lower half, arranged so as to reduce the force of the effort. Thanks to the invention, the smoothness and ease of opening and closing of a zippered device is comparable to the smoothness and ease of opening and closing a bag. Unsecured travel of the prior art occurs through straight lines along inside curves and corners.

A preferred process for assembling a device according to the invention comprises the following stages:

- Assembling overlapping zippers, for example, by sewing or welding with glue;

- Only then assemble the assembly with two zippers overlapping the suitcase, for example, by sewing or welding with glue.

Thanks to a preferred assembly process according to the invention, the two zippers are approximately the same length, which imposes a uniform movement with the single slider means despite the various curves on the various radii of the suitcase.

Despite the difference in radius, the top-sliding half and the bottom-sliding half actually move the same distance. This prevents offset in the movement of a single central sliding device.

Thanks to the preferred assembly process according to the invention, the teeth of the outside and inside zippers are aligned mainly in the vertical axis of the finished product, and the zippers are pulled towards each other as much as possible.

To facilitate the passage of the corners and prevent the risk of premature damage to the slide due to upper friction in the corners, the device is arranged with a single central slider to prevent "diving" and brake the slider and to compensate for differences in the length of the two zippers when placed at different radii.

For this reason, an increase in the width of the tape or hem relative to the prior art is provided to increase the passage of the sliding medium.

An increase in the size of the pre-art pull tab was also provided to facilitate the pull and advance of the sliding device.

The slider bridge is provided with a reduction in height and a tow eye handle placed on the bridge, which makes it possible for a long movement to the rear of the slider during opening and to the front of the slider during closing and which makes it possible to pull the center of gravity closer to the center of gravity of the slider, finally. To prevent "diving" and restrain the sliding device, any additional pressure exerted on the top or pointed tool only strengthens the plating of the outside zipper against the inside zipper by increasing locking activity and entry resistance. By force.

The invention may be implemented by one skilled in the art in accordance with variables, not shown, such that the activity of supporting and locking the teeth is obtained by achieving resistance to force entry.

The alignment of fasteners can vary within the scope of the invention, the primary being the achievement of the force entry resistance activity described in each of the embodiments described.

Internal and external zippers can be the same or different, both with regard to their shapes and with regard to their production materials. The inner and outer zippers can be placed symmetrically or apart from each other. The teeth of the zippers can be pointed towards the outside or inside of the luggage piece.

Finally, the invention covers embodiments using means with more than two overlapping zippers or having more than two sliding means, e.g., three overlapping zippers or three overlapping sliding means, with or without offset.

Preferred models use internal and external zippers that are pre-sewn before attaching to the shell of the corresponding luggage piece.

Any other additional means may be used which makes it possible to position the outside zipper against the inside zipper and resist forced entry without going beyond the scope of the invention: in particular, a VELCRO (registered trademark) type interlock against the inside zipper.

The invention also applies to a method obtained by attaching two zippers of different sizes to each other. In this variant, not shown, the slider has a different shape on the upper half than on the lower half to accommodate the two different zipper sizes. This variant, not shown, of a device with differentiated zippers is economical and is configured according to a curved shape and for easy and quick opening due to the different opening and closing speeds on the two zipper strips to prevent folds in one of the two zippers, offset movement, or locking of the sliding device and discrepancies in dimensions or specifications. Zipper sizes that can damage the quality and smoothness of the zipper after closing and opening.
