Patent Application
20070271674
This invention relates generally to load-bearing equipment. In an advantageous application, the invention relates more particularly to the attachment of load-bearing pouches to personally worn or carried items such as garments, packs or the like. In a particularly useful application, the invention relates to a versatile load-bearing vest.
Load-bearing vests are commonly worn as outer garments by police, emergency and military personnel who are required to carry a variety of items of equipment in an easily accessible location. Such items include water carriers, radios, batons, knives, handguns, ammunition, grenades and capsicum spray canisters. These items are usually carried in pouches attached to the vest.
Traditionally, the pouches are permanently fastened to the vests in fixed positions, eg. by being stitched into position. An example of a vest with stitched-on pouches for a variety of purposes is to be found in U.S. Pat. No. 5,617,582. Because the pouches are stitched in position, a police or military unit may require access to more than one different vest, perhaps several, each designed for a different operation.
In order to reduce the need for this enlarged inventory, there have been a number of proposals for vest systems in which the pouches are detachable and interchangeable, and the pouch array thereby reconfigurable. An early approach is disclosed in U.S. Pat. No. 4,106,121: the front panels of the vest have multiple pouch locations defined by velcro strips and snap fastener posts by which each pouch may be detachably fitted to the vest.
In a quite different arrangement, International Patent Publication WO 01/93710 describes a load carrying system including a panel of mesh which overlays the garment or pack. An array of holes complementary to the openings in the mesh is provided on the pouches. A stud-like fastener is used to secure each pouch to the panel by passing a shank through a registered pair of holes in the panel and in the pouch and using a keeper to secure the shank in place. The shank has a series of barbs or grooves to engage the keeper. Due to the array of holes provided by the mesh forming the panel, the pouches can be located at any of a variety of positions and moreover may be positioned at an angle to the vertical.
In a similar system that has been disclosed, instead of a panel of mesh overlaying the garment, the stud-like fasteners are employed to attach the pouches to the mesh openings in the vest itself: load-bearing vests are commonly of open-weave mesh construction to improve ventilation and minimize the vest's contribution to greater body heat.
Another reconfigurable system, adopted by some United States military personnel, has a vest with an attached array of vertical and horizontal webbing to which pouches are hooked by clips of a kind conventionally employed to fasten items to waist-belts.
An issue with the above described reconfigurable systems is the lack of reliability of the fastener arrangements. Where attachment is to mesh, the openings in the mesh are not stable and the fasteners tend to pull out through the holes. The fasteners are intended to be disengageable by hand, and so have a tendency to be too easily released when other forces are applied. This is unsatisfactory, for example, because personnel may be required to crawl along the ground or manoeuvre in situations where they would be brushing past objects. The fasteners are also considered too bulky, as they project from the garment. The stud-like fasteners have a small head and therefore create a localized pressure point, which is uncomfortable for the wearer.
It Is therefore an object of the invention, at least in a particular application, to provide a personal load-bearing system with a more reliable and durable pouch attachment system which is reconfigurable and comfortable for the user.
In a first aspect, the invention provides a load-bearing system having:
In a second aspect, the invention provides a load-bearing component for a load-bearing system having:
Advantageously, in either aspect of the invention, the load-bearing system is a personal load-bearing system, in which said web is of a form able to be worn or carried on the body of a person.
In one application, said web is in the form of a garment. More typically, said garment is a vest. Alternatively, said web is in the form of a pack, eg. a backpack. In a still further application, the web is a panel or plate, flexible or semi-flexible or rigid, adapted to be carried by a support surface. One such support surface might be on a vehicle. The panel or plate may be moulded, eg injection moulded, in a suitable material.
Advantageously, in the first aspect of the invention, said apertures are slots. In either aspect, the array of apertures comprises a multiplicity of parallel elongate slots, which preferably include subsets of aligned or co-linear slots. There may be plural sub-arrays of the slots in which the slots are respectively at different alignments, for example, in the case of a vest, horizontally, vertically and diagonally with respect to the orientation of the vest when being worn.
The apertures in the web are preferably of substantially stable dimensions and shape, and may have reinforced edges.
The vest is preferably a fabric, and the apertures thereon are preferably preformed during the manufacture of the fabric.
The attachment means is conveniently an elongate clip being a strip that either is preformed to define, or can be folded to define, two generally parallel overlaid arms that are integrally joined at one end and have fastener means for disengageably linking them at or adjacent the other end. In situ, the integral join and the fastener means traverse the respective pair of apertures in the arrays of apertures in the web and the pouch, whereby to form said closed loop.
The fastener means is preferably a snap-fastener, and is advantageously arranged for minimal protrusion outwardly of said strip forming the attachment means. Disengagement is preferably by use of a tool, so as to lessen the risk of accidental release.
In the first aspect of the invention, the secondary arrays of apertures in the respective pouches may be provided by a load-bearing system according to the second aspect of the invention, eg a system in the form of the aforementioned panel or plate.
The invention further provides, in a third aspect, a pouch component for a load-bearing system, including:
The invention will now be further described, by way of example only, with reference to the accompanying drawings, in which:
The web 12 includes a primary array of apertures 16 in addition to the holes of the open-weave mesh. Pouches 22 have a backing panel 23, fixed to the rear face 20 of the pouch body, for example by stitching 21 about the periphery of the backing panel. The term “panel” does not typically indicate a rigid component: any suitable material of adequate strength will suffice. A complementary secondary array of apertures 18 is formed in backing panel 23 as best shown in
In this embodiment, the apertures 16, 18 are elongate slots, with the slots 16 in the web 12 being of similar dimensions to the slots 18 in the rear face of 20 of pouches 22. Conveniently, slots 16 and 18 may be at 50 mm centres. The slots may typically be 3 mm or more in width and 6 mm or more in length.
The primary array comprises a multiplicity of slots 16 arranged in respective sub-arrays 17, 19 of slots 16a, 16b (
Slots 16, 18 are preformed during weaving of the fabric of web 12, and are typically reinforced at or near their edges.
When a pouch 22 is required to be attached to vest 14, backing panel 23 is positioned against the web 12 so as to match and align a set of parallel slots 18a, 18b of the secondary array with a set of slots 16a, 16b in the web array. In the illustrated case, there is a 2:1 ratio between the slot spacings. An attachment means in the form of an elongate clip 28 is passed through the pair of adjacent slots 18a, 16a and is then secured in position by fastener means 30 through slots 18b, 16b. Clip 28 is a flat strip that either is preformed to define, or can be folded to define, two generally parallel overlaid arms 29a, 29b that are integrally joined at one end and have fastener means 30 adjacent the other end. Fastener means 30 is a snap fastener comprising a pair of resiliently deflectable barbed prongs 31 on one arm 29a and a complementary socket 33 to receive the prongs and latch them behind an internal shoulder 35.
It will be seen that, once snap fastener 30 is engaged, clip 28 forms a closed loop through the respective pairs of apertures 16a, 16b; 18a, 18b of the primary and secondary arrays.
Snap fastener 30 is able to be engaged by hand, but preferably a tool must be used to disengage prong 31 from socket 33 and so detach the clip from the vest. This reduces the chance of the clips 28 accidentally unlocking during use. The tool may be originally made integrally with fastener 30, joined by web portions, such that the tool may be snapped off from fastener 30 and carried by the wearer of the vest. A suitable tool might comprise a handle with a small tubular head able to fit into space 37 in socket 33 about the prong 31, for engaging the tapered external surface 31a of the prong and deforming it sufficiently to release the prong from shoulder 35.
Even if the snap fastener 30 of a clip 28 were to disengage, a level of security is provided in that the clip will remain, at least for some time, attached at the other of the apertures 16 through which it is placed. This gives time for the slack attachment to be noticed and the clip re-fastened.
As can be seen in
As previously discussed, current systems use a stud-like fastener which is bulky and uncomfortable. Elongate clips 28 lie flat against the wearer's body and provide a secure, stable fixing at least two points, substantially without pouch rotation. Their elongate flat form avoids any localized pressure point, adding to the comfort of the wearer, and it will be further noted that the components of snap fastener 30 do not protrude outwardly of the strip of clip 28.
The pouch depicted in
The illustrated embodiment is a load-bearing vest. It is emphasized that the invention has much wider application, eg to other garments, to backpacks and other load carriers, and more generally to any system adapted to be carried by a support surface. The system might be, eg a panel or plate, flexible, semi-flexible or rigid according to application. A particularly convenient further application of the invention is to a vehicle.
It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
