(19) Referring initially to
(20) The multi-strap accessory holder 110 is provided to carry a wide variety of operational equipment (not shown) on the person of a first responder. The multi-strap accessory holder 110, in this particular embodiment, includes a holster 114, an accessory strap 116 and a detachable support strap assembly 118 having a first detachable support strap 120 and a second detachable support strap 122. The straps 116, 120 and 122 are engageable with one another and/or the holster 114. It should be noted that the disclosed multi-strap accessory holder 110 described herein is illustrative only and that many other configurations of multi-strap accessory holders 110 or strapped accessories are contemplated; for example, it is contemplated that the strapped accessory can include multiple holsters 114 or similar holsters, no holsters, more than one accessory strap 116, pouches or pockets suspended from the multi-strap accessory holder 110, etc.
(21) In this embodiment, the holster 114 is formed from two pieces of material including a J-shaped supporting panel 124 having a curved bottom portion 126 for supporting the weight of an accessory carried in the holster 114 and a curved side panel 128 affixed to the J-shaped supporting panel 124. The curved side panel 128 has a center portion 130 and first and second free ends 132 and 134. The J-shaped supporting panel 124 has a back panel 136 and a front panel 138 extending from opposite sides of the curved bottom portion 126.
(22) The holster 114 can be formed from a bulk thermal polyurethane (TPU) latex free coated polyester (preferably nylon) webbing material. One such material is BioThane available from BioThane Coated Webbing Corp. Unless expressed otherwise, the term BioThane will be used generically throughout the present disclosure to refer to any thermal polyurethane (TPU) latex free coated polyester (preferably nylon) webbing material used to manufacture the present invention. The shapes of the J-shaped supporting panel 124 and the curved side panel 128 can be formed by cutting the shapes from the bulk material with a thermal laser cutter which also fuses or seals the peripheral edges, such as the peripheral edge 140 of the J-shaped supporting panel 124 and the peripheral edges or free ends 132, 134 of the curved side panel 128 in a manner described in more detail hereinbelow. The laser cutter also forms and seals inner peripheral edges of any holes (not shown) formed through the J-shaped supporting panel 124 and the curved side panel 128 for receipt of rivets or other hardware as discussed hereinbelow.
(23) The use of a thermal laser cutter to form the shapes of and holes in the various straps, holsters, holders, belts, etc. provides a great advantage over simple mechanical cutting with a blade in that the thermal laser cutter fuses or seals the material as it cuts. For example, thermal laser cutting as disclosed herein renders the resulting shapes or cut parts waterproof along the cut edges and contributes to produce a fully waterproof accessory. The choice of BioThane as a preferred material for use in forming the disclosed waterproof strapped accessory assembly is based on its thermal melting point allowing the thermal laser cutter to fully seal any cut edges as well as its non-porous characteristics which prevent the absorption of fluids as well as allowing for ease of field cleaning. Other similar materials may be used in the disclosed method depending on the availability, cost efficiency and/or desired flexibility.
(24) To assemble the holster 114, first rivets 144 are inserted through the sealed holes (not shown) formed through the back panel 136 of the J-shaped supporting panel 124 and through the sealed holes (also not shown) formed through the first and second free ends 132 and 134, respectively, of the curved side panel 128. The first rivets 144 are then secured in known manner to affix the first and second free ends 132 and 134 to the back panel 136. The front panel 138 of the J-shaped supporting panel 124 is similarly affixed to the center portion 130 of the curved side panel 128 by inserting a second set of rivets 146 through holes (now shown) formed through the center portion 130 of the curved side panel 128 and the front panel 138 and secured therein in known manner as above.
(25) Additionally, various hardware 150 may be provided on the holster 114 to retain equipment therein as well as releasably secure the holster 114 to other straps. For example, a button 152 may be provided through a hole (not shown) in the center portion 130 of the curved side panel 128 and secured therein. A stretchable cord 154, extending from one or more holes 156 formed through the back panel 136 of the J-shaped supporting panel 124, is provided to retain any equipment in the holster 114 and can be releasably secured to the button 152. It should be noted that the hardware 150, as well as any other hardware utilized in the waterproof strapped accessory assembly 100, is preferably formed of a bio-compatible, non-absorbent, easily cleanable and sterilizable, non-corroding material, such as stainless steel.
(26) Likewise, a pair of mini-straps 160 and 162 may be formed by the method disclosed herein and secured to the back panel 136 of the J-shaped supporting panel 124 using rivets 164. The securement of the mini-straps 160 and 162 to the back panel 136 is loose enough to allow the mini-straps 160 and 162 to rotate relative to the J-shaped supporting panel 124 to allow for rotational movement of the mini-straps 160 and 162 as they are attached to other straps or equipment. The mini-straps 160 and 162 are provided with D-rings 166 and 168. The D-rings 166 and 168 are secured to the mini-straps 160 and 162, respectively, by inserting the mini-straps 160 and 162 through the D-rings 166 and 168 and folding the mini-straps 160 and 162 back over themselves prior to the insertion of the rivets 164.
