The specific embodiment
Detachable overboard life-support back pack as Figure 1-3, comprise knapsack body 1, braces 2, attached cover 3 and handle 4, attached cover 3 is suitable with the back shape size of knapsack body 1, braces 2 is fixedly connected on the back of attached cover 3, the anterior periphery of attached cover 3 and the back periphery of knapsack body 1 are provided with zipper strip 5, on this zipper strip 5, have the breach 6 that disconnects this zipper strip 5, on the zipper strip 5 of these breach 6 one end, is furnished with the first slider of zipper fastener 7 between the chain tooth that is held on zipper strip 5, the drawing direction of the first slider of zipper fastener 7 is towards breach 6, the zipper strip 5 of these breach 6 other ends is furnished with the second slider of zipper fastener 8 between the chain tooth that is held on zipper strip 5, the drawing direction of the second slider of zipper fastener 8 is towards breach 6, handle 4 covers breach 6, the first slider of zipper fastener 7 and the second slider of zipper fasteners 8, and handle 4 is connected with the second slider of zipper fastener 8 with the first slider of zipper fastener 7 respectively, and is removably connected with knapsack body 1 and/or attached cover 3.Wherein, the handle 4 of the present embodiment is connected with the second slider of zipper fastener 8 with the first slider of zipper fastener 7 respectively through two stay cords 9.
As shown in Figure 1, Figure 3, when handle 4 covers on breach 6, the first slider of zipper fastener 7 and the second slider of zipper fastener 8, the first slider of zipper fastener 7 and the second slider of zipper fastener 8 are fixed under the installation clamping power effect of handle 4, the first slider of zipper fastener 7 and the second slider of zipper fastener 8 cannot be easily to breach 6 places or oppositely the direction at breach 6 places pull, thereby kept attached cover 3 to be connected with the reliable of knapsack body 1 by zipper strip 5, be applicable to carry on the back at ordinary times article and use.
As shown in Figure 2, when handle 4 is pulled down, handle 4 pulls drive the first slider of zipper fastener 7 and the second slider of zipper fastener 8 separately towards breach 6 places, make the chain tooth of zipper strip 5 lose the clamping constraint of the first slider of zipper fastener 7 and the second slider of zipper fastener 8, in attached cover 3 and knapsack body 1, the chain tooth of zipper strip 5 is by related disengaging, thereby quick separated knapsack body 1 and attached cover 3 prevent that knapsack body 1 from becoming the heavy burden of user when overboard.While reusing, the first slider of zipper fastener 7 and the second slider of zipper fastener 8 are clamped back between the chain tooth of zipper strip 5 and reset.
Also, the detachable setting of handle 4, while making handle 4 fixedly, although can also keep positive engagement with the chain tooth of jagged 6 zipper strip 5, the chain tooth that can pull down rear zipper band 5 at handle 4 again can depart from fast.Wherein, the present embodiment arranges handle 4 and is all removably connected with attached cover 3 with knapsack body 1, can improve the stable connection degree of handle 4, improve the chucking power of handle to breach 6, the first slider of zipper fastener 7 and the second slider of zipper fastener 8, effectively prevent that the first slider of zipper fastener 7 and the second slider of zipper fastener 8 are loosening; Handle 4 is selected to be removably connected with knapsack body 1 or attached cover 3, can further improve the speed that handle 4 is pulled down, for drowning people provides the speed of rescuing faster.
As Figure 2-3, handle 4 is connected with knapsack body 1 through a life line 10, and life line 10 is placed in attached cover 3 and encloses in the space of formation with the back of knapsack body 1.When other people are overboard, the handle 4 of pulling down, can together fling at drowning people together with knapsack body 1 through life line 10, and drowning people can catch knapsack body 1 to be saved under the pulling force of life line 10.
For making knapsack body 1 and/or braces 2 be unlikely to form drowning people's heavy burden, in order to improve the buoyancy of knapsack body 1 and/or braces 2, the present embodiment is folded with at the back of knapsack body 1 for the first kickboard (not shown) of buoyancy is provided.In attached cover 3, be folded with for the second kickboard (not shown) of buoyancy is provided, the front portion of attached cover 3 is provided with slide fastener 31, pulls open this slide fastener 31, can be convenient the second kickboard be inserted or take out replacing; On braces 2, be equipped with for the 3rd kickboard 21 of buoyancy is provided.The buoyant sheet material of tool in water or filler that the first kickboard, the second kickboard and the 3rd kickboard 21 can adopt foam, light plastic or wood materials to make.
As shown in Figure 3, for ease of taking in life line 10, the back of knapsack body 1 is provided with pocket 11, and life line 10 is placed in this pocket 11, and one end of this life line 10 is connected in pocket 11, and the other end of life line 10 is connected in handle 4.Longer life line 10 can be wound around and be placed in pocket 11.
For 1 buoyancy that can provide of knapsack body of throwing is provided, in pocket 11, be provided with folding air bag 12.As shown in Figure 4, the air bag 12 of the present embodiment comprises bag-shaped airbag body 121, has opening 122, and the medial margin of this opening 122 is with the bonding sealing of VELCRO.By 122 of openings, can enter air toward the interior pocket of airbag body 121, then with VELCRO sealing opening 122, formation can provide at the water surface air bag 12 of buoyancy.
For preventing that air bag 12 from comparatively fast leaking gas at opening 122 places of VELCRO sealing, the lateral border of opening 122 is fixed with a cingulum 123, this cingulum 123 is along the circumferential extension setting of opening 122, the two ends of cingulum 123 are respectively equipped with the element 124 of mutual fastening, and element 124 can be set to the modes such as clip, buckle, snap-on; Between cingulum 123 after two element 124 fasten and the airbag body 121 at opening 122 places, enclose and form buckle ring 125.As shown in Fig. 5-6, the airbag body 121 at opening 122 places can carry out rolling along cingulum, make opening 122 obtain effective sealing, simultaneously, buckle ring 125 can be used for being buckled on the parts of braces 2 annulars such as grade, be beneficial to the installation of air bag 12, and hold air bag 12 without drowning people's water, improved drowning people's self-saving ability.
As Figure 1-3, for the benefit of convenient mounting or dismounting of handle 4, handle 4 comprises adhesive strip 41 and the handlebody 42 being stretched out by the end face of adhesive strip 41, the bottom surface of adhesive strip 41 is provided with VELCRO and hooks face 43; Knapsack body 1 one sides at breach 6 places and attached cover 3 one sides at breach 6 places are provided with VELCRO and hook the bonding VELCRO hair side 13 of face 43.The adhesive strip 41 of handle 4 through VELCROs hook faces 43 can with VELCRO hair side 13 rapid-assembling/disassemblings.Also only knapsack body 1 one sides at breach 6 places arrange VELCRO hair side 13, or only attached cover 3 one sides at breach 6 places arrange VELCRO hair side 13, can with VELCRO, hook the handle 4 of face 43 by rapid-assembling/disassembling equally.
In addition, VELCRO can be hooked to the location swap of face 43 and VELCRO hair side 13, handle 4 also can be set to as modes such as magnetic attracting is connected, the connection of adhesive sticker viscosity, slide fastener connection, clip connections with the mode that removably connects of knapsack body and/or attached cover 3.
Above-mentioned embodiment is only the preferred embodiment of the present invention; can not limit the scope of protection of the invention with this, the variation of any unsubstantiality that those skilled in the art does on basis of the present invention and replacement all belong to the present invention's scope required for protection.
