BAG EQUIPPED WITH LOAD DISTRIBUTION ATTACHMENT

Description

Technical Field of the Invention The invention relates to a bag equipped with a load distribution accessory.

It concerns the general technical field of backpacks or packages carried by the human body. State of the art

A load transported in a bag is transmitted to the back of the wearer by shoulder straps that pass over the shoulders of said wearer. If the load is important, the weight of the bag is mainly transferred to the hips (in the event that a lap belt is fitted to the bag) and to the wearer's shoulders, which may feel excessive and uncomfortable pressure at this level of the body. . Many solutions have been proposed to reduce this uncomfortable distribution of the load on the shoulders of the wearer.

The patent documents EP 2,371,232 (ADIDAS) or FR 2,701,135 (Rossignol) describe for example a bag comprising a pair of straps. A portion of the upper portion of each strap consists of an elastic portion limited in elongation. This elastic portion aims to uncouple the backpack of the wearer to improve comfort by allowing the wearer to feel less on his shoulders movements, usually abrupt, during the practice of sport or when moving the carrier .

Patent EP 0,570,193 (KARRIMOR) discloses an epaulet for the shoulder strap of a bag, which comprises an elongated synthetic foam member comprising one or more relatively rigid plastic sheets mounted on its side remote from the wearer's body. The shoulder pad contains a plurality of relatively rigid elongate plastic strips disposed side-by-side along the length of the foam member, separated by spacings. When such an epaulette is used on the backpack, the transmission area is increased, which increases the comfort of the wearer and / or the load capacity. Thanks to the elongated bands, the load is spread out and the shoulder pads become flexible.

The patent document EP 2.606.763 (WOOHYUNG) discloses a shoulder strap of a bag comprising an air-swellable portion. This air cushion not only reduces the effect of pressure on the wearer's shoulder, but also, when in close contact with the shoulder, to prevent the bag from slipping or moving sideways.

The patent document EP 1.499.212 (COMPAGNIA DEL VIAGGIO) discloses a strap for carrying a bag provided with an additional member to better distribute the weight of the bag on the shoulders of the user. This additional member is composed of articulated segments.

In all the aforementioned technical solutions, the straps support mainly on the shoulders and clavicles of the wearer so that the shoulders and clavicles remain solicited. The invention aims to remedy this state of affairs. In particular, an object of the invention to deport all or part of the weight of the shoulder bag of the wearer, to improve comfort and / or increase the load to wear.

Another object of the invention is to provide a bag with which the weight of the load is better distributed on the wearer's body.

Disclosure of the invention.

The solution proposed by the invention is a bag comprising a right shoulder strap and a left shoulder strap adapted, in use, to be installed respectively at the right shoulder and the left shoulder of a wearer.

This bag is remarkable in that: - a stiffening reinforcement equips at least one of the carrying straps, - the stiffening reinforcement has a crooked upper hook portion, which upper portion is extended downwards by a longitudinal portion, O the hooked upper hook portion is located, in use, at the shoulder on which is installed the carrying strap equipped with the stiffening reinforcement, O the longitudinal portion extends in the length of said carrying strap, O the longitudinal portion is shaped so that, in use, said shoulder strap is pressed against a region of the trunk of the wearer other than the shoulder on which said shoulder strap is installed, all or part of the load of said bag being distributed at the level of this support. The frame forms a load distribution accessory that makes it possible to no longer carry all or part of the weight of the bag on the shoulder and the clavicle of the wearer. The weight of the bag is now offset, at least in part, to a support zone that can be more stressed than the shoulders, with a degree of comfort acceptable to the wearer. The bag then seems lighter to wear for the wearer. Other advantageous features of the invention are listed below. Each of these features may be considered alone or in combination with the remarkable features defined above, and may be subject, where appropriate, to one or more divisional patent applications: The reinforcing reinforcement advantageously consists of a blade flat having the general shape of a cane. - The longitudinal portion preferably has a segment which is twisted about the longitudinal axis of said longitudinal portion so that, in use, the carrying strap equipped with the stiffening armature is pressed against the lateral part of the torso, at the flanks, in the region of the hypochondrium and / or the lateral flanks of the wearer. This twisted segment is advantageously extended downwards by a lower segment, which segment is straight or curved or curved or broken line. This twisted segment is preferably twisted a quarter turn around the longitudinal axis of the longitudinal portion. - The stiffening armature can be inserted removably in a sheath arranged inside the carrying strap, which sleeve has an opening for the insertion of said armature. - The stiffening frame can be installed on the shoulder strap, fastening means ensuring the maintenance of said frame on said ramp. - The stiffening frame can be inserted permanently inside the carrying strap, which armature forms the soul of said ramp. - The stiffening reinforcement is preferably carried out in a rigid or semi-rigid and flexible material, having elastic properties. - The reinforcing frame is advantageously made of a material selected from the following list: PVC, stainless steel, aluminum alloy, copper alloy, brass alloy; glass fibers or carbon fibers mixed with a thermoplastic or thermosetting resin, laminated wood, glulam. - The upper curved hook portion is advantageously shaped so that, in use, the shoulder strap is shifted forwardly and / or upward of the clavicle associated with the shoulder of the wearer on which is installed said ramp. - The upper curved hook portion is advantageously shaped so that, in use, the shoulder strap is shifted forwardly and / or upward of the shoulder of the carrier on which is installed said ramp. - Each carrying strap is preferably equipped with the stiffening frame. In this case, the longitudinal portion of each stiffening reinforcement advantageously has a segment which is twisted around the longitudinal axis of said longitudinal portion; the twisted segment of the stiffening frame equipping the right shoulder strap being twisted in one direction (preferably in the clockwise direction) about the longitudinal axis of the longitudinal portion of said frame; and the twisted segment of the stiffening armature equipping the left shoulder strap being twisted in another direction (preferably in a counter-clockwise direction) around the longitudinal axis of the longitudinal portion of said armature.

Another aspect of the invention relates to a load distribution accessory for a bag carrying shoulder strap, comprising at least one stiffening reinforcement adapted to equip a bag carrying strap, which stiffening reinforcement has a hooked upper portion which hooks is extended downwardly by a longitudinal portion, which longitudinal portion has a segment which is twisted about the longitudinal axis of said longitudinal portion.

FIG. 5 illustrates, in an overall front view, a bag according to the invention carried by a wearer; FIG. 6 illustrates, in an overall side view, a bag according to the invention worn; by a carrier.

Preferred embodiments of the invention The invention relates to a bag to be worn by a human body. It can be a travel bag, a sports bag, a golf bag, a hiking bag, a military bag or fireman, a schoolbag, a baby carrier, etc. In general, this bag is designed to carry a load: clothing, notebooks, military equipment, oxygen cylinder, fire hose, books, sports accessories, baby, etc.

Figure 1 shows a bag 1 of the backpack type. This bag 1 is of a classic design. It includes an internal cavity to receive the load to wear. It has a rear face 10 which, in use (that is to say when the bag 1 is worn), is in contact with the back of the wearer.

To improve the comfort of the carrying, the lower end of the rear face 10 of the bag 1 may optionally extend on each side to form hip extensions 10a, 10b of the wearer. Each of these extensions 10a, 10b can then be provided with a two-part abdominal or ventral belt 100a, 100b, which makes it possible to fix the lower part of the bag 1 around the size of the wearer. In Figure 4, an attachment loop 100c secures the two parts 110a and 100b of this belt. The latter is well known to those skilled in the art. This abdominal belt is however not necessary for the implementation of the invention, Figure 5 illustrating, for example, a bag 1 which is devoid of it.

To further improve the comfort of the wearer, the rear face 10 may be provided with lumbar supports 10c in excess thickness.

The bag 1 comprises a pair of carrying straps, respectively a right shoulder strap 11a and a left shoulder strap 11b, which straps are disposed on the rear face 10. In use, and as shown in FIG. 5, the right shoulder strap 11a is installed in the level of the right shoulder ED of the wearer P and the left shoulder 11b is installed at the level of his left shoulder EG. These straps 11a, 11b are generally flat. Their width is for example between 10 mm and 100 mm.

Without the stiffening frames 2a, 2b described in the description above, the straps 11a and 11b are flexible, that is to say, easily manually deformable. They each have an upper end, respectively 110a and 110b, which are fixed on the upper part of the rear face 10, for example by stitching. They also each have a lower end, respectively 111a and 111b, which are fixed on the upper part of the rear face 10, for example by stitching. The lower ends 111a and 111b are advantageously attached to the lower part of the bag 1 by means of adjustment straps, respectively 12a and 12b which make the straps 10a, 10b adjustable in length. The upper end 120a, 120b of the straps 12a, 12b is advantageously connected to the lower end 111a, 111b of the straps 11a, 11b by a control loop (not shown). In Figure 1, the lower end 121a, 121b of the straps 12a, 12b is attached to the hip extension 10a, 10b, for example by stitching. In Figure 6, the lower end 121a, 121b of the straps 12a, 12b is directly attached to the bottom of the rear face 10, for example by sewing.

The straps 11a, 11b may also be provided with a two-part ventral fastener 119a, 119b, which allows a better adjustment of the position of the bag 1 and the position of said straps according to the anatomy and morphology of the wearer P. On Figure 4, an attachment loop 119c secures the two parts 119a and 109b of this fastener.

In Figure 1, each strap 11a and 11b is twisted on itself. This twisting movement of the shoulder straps 11a and 11b is made possible by a stiffening reinforcement which equips each of said straps.

These stiffening frames are shown in Figures 2a, 2b, 3a and 3b. The armature equipping the right shoulder strap has the reference 2a, and the armature equipping the left shoulder 11b bears the reference 2b.

These reinforcements 2a, 2b are advantageously thin, that is to say that their section has a width Ί "which is greater than their thickness" e "(Figure 2c), for example the width Ί" is between mm and 80 mm and the thickness "e" between 2 mm and 5 mm. The thinness of the frames 2a, 2b gives them lightness, flexibility and elasticity.

As illustrated in Figure 2a, 2c and 3a, the armatures 2a, 2b are preferably in the form of flat blades, rectangular section, having the general shape of a rod. The reinforcements 2a, 2b may however have another section, in particular a slightly curved concave section (FIG. 2d) so as to further marry the wearer's morphology.

The armatures 2a, 2b are made of a rigid or semi-rigid and flexible material, having elastic properties, said armatures being able to deform elastically, reversibly. This elasticity allows the frames 2a, 2b to best follow the curvature of the straps 11a, 11b and that of the trunk of the carrier P, with a spring effect, as explained in detail further in the description. The frames 2a, 2b may be made of: plastic such as PVC; - Of metal such as stainless steel, aluminum alloy, copper alloy, brass alloy; composite material such as glass fibers or carbon fibers mixed with a thermoplastic or thermosetting resin; laminated wood, glue-laminated wood; - etc. Any other material suitable to those skilled in the art can be used.

Each armature 2a, 2b has a hooked upper portion, respectively 20a, 20b, which is located, in use, at the shoulder ED, EG on which is installed the shoulder strap 11a, 11b equipped with the armature 2a, 2b respectively. These hook portions 20a, 20b preferably have the shape of an arc whose curvature is adapted to the morphology of the ED, EG shoulders of the wearer P.

Each hook portion 20a, 20b is extended downwardly by a longitudinal portion 21a, 21b respectively, which extends in the length of the carrying strap 2a, 2b. Preferably, each armature 2a, 2b is extended in, or on, the strap 11a, 11b respectively, substantially from the upper end 110a, 110b to the lower end 111a, 111b. By "substantially" is meant that the unrolled length of each armature 2a, 2b may be equal to or less than, for example, a few centimeters, at the unrolled length of the ramp 11a, 11b respective. The upper end 200a, 200b of the armatures 2a, 2b (that is to say the free end of the hook portions 20a, 20b) may not reach the upper end 110a, 110b of the straps 11a, 11b. Similarly, the lower end 210a, 210b of the armatures 2a, 2b (that is to say the free end of the longitudinal portions 21a, 21b) may not reach the lower end 111a, 111b of the shoulder straps 11a, 11b . However, the best results are obtained when these different ends coincide.

The unwound length of the armatures 2a, 2b (length between the ends 200a-210a, 200b-210b) is for example between 200 mm and 600 mm, the length of the longitudinal portions 21a, 21b being for example between 100 mm and 400 mm . This length depends on the anatomy and / or morphology of the wearer, the latter may be a child schoolboy, a teenager, an adult, and a man or a woman.

Various techniques for securing the reinforcements 2a, 2b to the straps 11a, 11b will now be explained in detail, with reference to Figures 4a, 4b and 4c.

In the embodiment of Figure 4a, each armature 2a, 2b is installed inside the strap 11a, 11b. The frames 2a, 2b can thus be placed or removed from the traditional shoulder straps 11a, 11b as desired by the wearer. When the frames 2a, 2b are removed, the wearer finds a conventional bag.

The strap 11a, 11b is flexible and formed by a padded layer 114a, 114b or padding, for example elastomer foam, which layer is covered with a protective material 116a, 116b of the fabric, plastic, leather, etc. type.

Each armature 2a, 2b is inserted into a sheath 115a, 115b arranged inside the strap 11a, 11b. This sheath 115a, 115b has a section that corresponds to that of the armature 2a, 2b, its dimensions may however be slightly greater, for example a few millimeters, to facilitate the insertion of said armature. Its length corresponds to that of the frame 2a, 2b. The strap 11a, 11b thus serves as sleeve or sheath, in which is housed the frame 2a, 2b.

The sheath 115a, 115b has an opening 1150a, 1150b through which the armature 2a, 2b is inserted. This opening 1150a, 1150b is advantageously placed at the upper end 110a, 110b of the ramp 11a, 11b. This position of the opening 1150a, 1150b facilitates the insertion of the frame 2a, 2b. First slide the lower end 210a, 210b of the armatures 2a, 2b in the sheath 115a, 115b through the opening 1150a, 1150b, then continue the insertion of the longitudinal portion 21a, 21b to end by insertion of the hook portion 20a, 20b.

To ensure that the armature 2a, 2b remains well positioned and / or leaves the sheath 115a, 115b, the opening 1150a, 1150b is preferably closed by a closure flap 1151a, 1151b. This flap is advantageously made of the same material as the protective material 116a, 116b and is advantageously an extension of the latter. Fastening means 1152a, 1152b and 1153a, 1153b are advantageously provided respectively on the flap 1151a, 1151b and on the strap 11a, 11b, so as to maintain said flap in the closed position. These attachment means 1152a, 1152b, 1153a, 1153b may be Velcro® type, snaps, etc.

In the embodiment of Figure 4a, the armature 2a, 2b is installed on the carrying strap 2a, 2b. The frames 2a, 2b can thus be added to traditional shoulder straps 11a, 11b or be removed as desired by the wearer. When the frames 2a, 2b are removed, the wearer finds a conventional bag.

The strap 11a, 11b is of the type described above with reference to FIG. 4a. The stiffening armature 2a, 2b comes to cover the strap 11a, 11b. It covers more particularly the protective material 116a, 116b, and is placed on the outer face of the strap 11a, 11b, that is to say the face which is not in contact with the body of the wearer.

To maintain the position of the armature 2a, 2b on the shoulder strap 11a, 11b, fixing means 117a, 117b are provided, for example in the form of loops or loops, distributed mainly or part of the length of said ramp. One can also consider keeping the armature 2a, 2b on the ramp 11a, 11b by means of Velcro® type hook and loop tape.

To ensure that the armature 2a, 2b remains well positioned on the shoulder strap 11a, 11b, its upper end 200a, 200b and its lower end 210a, 210b, are advantageously housed in abutment pieces 118a, 118b. The latter are for example in the form of pockets sewn on the outer face of said strap and in which the ends 200a, 200b and 210a, 210b of the armature 2a, 2b.

In the embodiment of Figure 4c, each frame 2a, 2b is permanently inserted into the strap 11a, 11b. As described above with reference to FIG. 4a, the shoulder strap 11a, 11b is formed by a padded or padded layer 114a, 114b, for example made of elastomer foam, which layer is covered with a protective material 116a, 116b of the type fabric, plastic, leather, etc. The armature 2a, 2b now forms the web of the strap 11a, 11b, being surrounded by the layer 114a, 114b, to which it can be secured for example by gluing.

When the frames 2a, 2b are associated with the straps 11a, 11b, the latter take the form of said frames. The frames 2a, 2b therefore make it possible to conform the straps 11a, 11b. This property is used, in the context of the invention, to create new points or zones of support of said shoulder straps in a region of the trunk of the wearer other than the shoulders ED, EG.

In the preferred embodiment of Figures 2a, 2b, 3a and 3b, each longitudinal portion 21a, 21b has a segment 211a, 211b which is twisted on itself or, in other words, twisted around the longitudinal axis Aa, Ab of said longitudinal portion. This longitudinal axis Aa, Ab corresponds to the line which passes through the center of the section of said longitudinal portion 21a, 21b respective. This line can be straight or curved. The twisted segments 211a, 211b can be obtained directly during the molding of the reinforcements 2a, 2b or of their shaping. For example, it is possible to use a thermoformable material, such as PVC, to heat it and to apply a hot twist to obtain the twist, the cooled reinforcement keeping this shape. Each twisted segment 211a, 211b is extended downwardly by a segment which is advantageously straight 212a, 212b.

In traditional bags, straps pass over the shoulders and clavicles of the wearer, descend against the chest and then pass under the armpits. The shoulders and pectorals are therefore the main support zones of the shoulder straps, most of the weight of the load being taken up at the level of said shoulders. To remedy this, the twisted segments 211a, 211b conform the straps 11a, 11b so that, in use, said straps bear against a region of the trunk of the wearer P other than the shoulders ED, EG and / or CD clavicles, CG. More particularly, as shown in Figures 5 and 6, these twisted segments 211a, 211b will print a torsion movement straps 11a, 11b so that the latter follow at best the curvature of the trunk of the wearer P and are pressed against the lateral part of the torso, at the level of the flanks F, and more precisely in the region of the hypochondrium and the lateral flanks. The straps 11a, 11b are thus in abutment against this lateral region of the wearer's torso, which they clasp mainly at the lower segments 21a, 212b, in the manner of a clamp. More particularly, when the carrier P installs the bag 1 on his shoulders ED, EG, the straps 11a, 11b equipped with the frames 2a, 2b deviate at the sidewalls F and act as jaws elastically deforming, with an effect spring, to grip, without injury, the trunk of the wearer P. All or part of the weight of the load is then deported and distributed at the level of this new support zone, discharging the shoulders ED, EG and / or CD collarbones , CG, all or part of the weight they initially supported without the use of the frames 2a, 2b.

It is advantageous for the support surface of the shoulder straps 11a, 11b to be maximum at the level of the flanks F of the carrier P. This makes it possible not only to increase the load transfer on this bearing zone, but also to improve the comfort. . To do this, the twisted segments 211a, 211b are preferably twisted a quarter turn around their respective longitudinal portion 21a, 21b. Thus, each lower segment 212a, 212b is at an angle of about 90 ° (+/- 5 °) with the hook portion 20a, 20b. In this way, the straps 11a, 11b pass at the shoulders ED, EG in their width and pass at the level of the sidewalls F also in their width.

To optimize the comfort and improve the plating of the shoulder straps 11a, 11b against the sidewalls F of the carrier P, the twisted segments 211a and 211b are not twisted in the same direction. The twisted segment 211a of the armature 2a equipping the right shoulder strap 11a is twisted clockwise (referenced Sa in FIG. 2a), about the longitudinal axis Aa of the longitudinal portion 21a, while the twisted segment 211b of the armature 2b equipping the ramp 11b is twisted in a counterclockwise direction (referenced Sb in Figure 2b), about the longitudinal axis Ab of the longitudinal portion 21b.

The conformation of the straps 11a, 11b given by the armatures 2a, 2b thus makes it possible to stress the shoulders ED, EG of the carrier P less since all or part of the weight of the load is offset at the level of the flanks F. Also, it seems advantageous that the hook portions 20a, 20b are shaped so that, in use, the shoulder straps 11a, 11b are shifted forwards and / or upwards from the clavicles CD, CG and / or the shoulder ED, EG of the wearer P. In practice, and as shown in Figure 6, it is expected that the curvature of the hook portions 20a, 20b is greater than that of the shoulders ED, EG so that said portions are not, or little, in support against shoulders ED, EG and / or clavicles CD, CG of the wearer P. The straps 11a, 11b extend towards the back of the bag 1 and upwards, above the shoulders ED, EG and / or clavicles CD , CG, then descend down the flanks F. The shoulder straps 11a, 11b may take a slightly arched shape so as to return to the rear face 10 of the bag 1, passing through the flanks F.

The reinforcements 2a, 2b ultimately form a load distribution accessory which makes it possible to no longer carry all or part of the weight of the bag 1 on the shoulders ED, EG. The physical integrity of the clavicles CD, DG is also more respected than with a conventional bag.

This accessory allows to shift the weight of the bag 1 to a support zone that can be more stressed than the shoulders, with a degree of comfort acceptable to the wearer. The inventor has found that when a conventional bag had his shoulder straps equipped with frames 2a, 2b, the load to wear could be increased from 10% to 30% without significant perception for the wearer. In other words, for the same load, a bag whose straps are equipped with frames 2a, 2b seems lighter for the wearer. An increase of 10% to 30% of the load is on the contrary negatively felt by the wearer, with the same bag but whose straps are not equipped with frames 2a, 2b.

In addition, when the straps 11a, 11b are equipped with frames 2a, 2b, they become generally stiffer than traditional straps. These straps 11a, 11b and equipped form handles that the wearer can easily grasp to set up his bag 1. And in general, the establishment of shoulder straps 1a, 11b is faster and easier. The arrangement of the various elements and / or means and / or steps of the invention, in the embodiments described above, should not be understood as requiring such an arrangement in all implementations. In any case, it will be understood that various modifications may be made to these elements and / or means and / or steps, without departing from the spirit and scope of the invention. In particular: - Only one of the straps 11a or 11b can be equipped with a stiffening frame; the inventor has indeed found that even with a single ramp equipped with a frame 2a, 2b, satisfactory results were obtained in terms of comfort of carriage and that the load to be carried could be increased by about 10% to 30% compared to a bag whose strap was not equipped with stiffening reinforcement. - The section of the hook portion 20a, 20b may be different from that of the longitudinal portion 21a, 21b. The section portion of the longitudinal portion 21a, 21b may in particular be wider than that of the hook portion 20a, 20b so as to increase the bearing area on the trunk of the wearer. - Each twisted segment 211a, 211b may extend downwardly by a segment 212a, 212b which is not straight, for example a curved segment, curved broken line, or other, so as to better adapt to the morphology flanks F of the wearer and improve the support of the straps against the trunk of the wearer P. - Each twisted segment 21a, 211b can be twisted more or less a quarter turn around the longitudinal axis Aa, Ab of the portion longitudinal 21a, 21b, depending on the anatomy and / or the morphology of the carrier P. Thus, each lower segment 212a, 212b may for example make an angle between 30 ° and 160 ° with the hook portion 20a, 20b - The reinforcements 2a, 2b may not be flexible. In this case, the strap is padded with a protective foam, for example latex, so as not to affect the comfort of the wearer. The longitudinal portion may be shaped so that, in use, the strap 11a, 11b is pressed against a region of the trunk of the wearer other than the shoulder D, EG, and other than the lateral part of the torso, in particular other than the flanks F, in the region of the hypochondrium and / or the lateral flanks of the carrier P. The longitudinal portion may for example be shaped so that, in use, the strap 11a, 11b is pressed against the pectorals In this case, the segment 211a, 211b is not necessarily twisted, but can be concave or curved, to fit the shape of the pectoral and rely on it.
