Description
Technical field
The utility model relates to a kind of knapsack shoulder belt with pooling feature, be meant an a kind of end that is combined in by the knapsack appearance extend out and bend back and be attached to knapsack the other end bear band, it comprises and is used for relaxing, disperseing the toter's shoulder and the absorbing structure of pressure that muscle bears on every side, is meant this type of knapsack room band of a kind of effectively dispersive pressure, in light weight and good air permeability especially.
Background technology
Many traditional knapsack shoulder belts with pooling feature are to press close to the rectangular bag with wide flat section that one section adding of knapsack toter shoulder, chest is sewn into by the preferable cloth of tensile strength when using on its shoulder belt, and described cloth pocket wall is sponge, cotton-wool or the soft foam material buffering filler of wide flat by both sides double team integral body up and down; And because aforesaid sponge, cotton-wool or soft foam material buffering filler rerum natura are loose, body is difficult for keeping, usually also will be up and down two cloth pocket walls be sewn at the midline position of bag body along the shoulder belt trend together with the filler of institute's double team between the two, make that filler position in bag is comparatively fixing; Have many in addition in the hollow bag, the upside (away from a side of health) of aforesaid sponge, cotton-wool or soft foam material buffering filler, the foam material that adds the more aforementioned filling object height of one deck density helps keep the shape of described rectangular bag, makes it be difficult for torsional deformation.
The major defect of this class knapsack buffering shoulder belt comprises that gas permeability is bad and meet water and is difficult for air-dry.Though the bad reason of gas permeability is that many micro air chamber (bubble) are arranged in most foam materials, but air chamber is completely cut off by plastics each other, basically do not communicate, so foam material is difficult ventilative or even air-locked basically, just why foam material can be used on the utensil of insulation, cold insulation for this; If adopt the flocculence filler, undesirable though its gas permeability is good slightly than foam material because of its cushioning effect, nowadays very lack and use herein.Meet water and be difficult for air-dry shortcoming and then adopt aforementioned which kind of material all to be difficult to avoid as the buffering filler, intaking easily, absorb water and maintain moisture between the fiber of flocculence filler and fiber no doubt is general general knowledge; On foam material, though its many micro air chamber do not communicate basically each other, the water imbibition that only adds the hole more than the small hole quantity on its surface well be enough to cause drench with rain or clean after air-dry difficulty.These shortcomings are necessary to design via improvement knapsack shoulder belt absorbing structure and are overcome.
In order to overcome the problems referred to above, in recent years, some new knapsack shoulder belt absorbing structure designs had appearred on the market.The design that these are new, the same with traditional design is, has also comprised one by two rectangular bags with wide flat section that the preferable cloth of tensile strength is sewn into up and down.Different is that the buffering filler that holds in the bag with the cushion pad of the made special shape structure of elasticity macromolecular material, replaces traditional sponge, cotton-wool or soft foam material.Wherein a kind of cushion pad as shown in Figure 3, cushion pad 31 comprises the rib 311 of a series of almost parallels each other and another series rib 312 of almost parallel each other, and rib 311 and rib 312 intersect mutually and link and so form the air-vents 313 of many up/down perforations.Though such design has the advantage of good air permeability, but because rib 311 intersects to form numerous bindings mutually with rib 312, and the height of each binding (thickness) is quite big, causes structural bending to spend strong and is difficult for stressed bending, also brings the effectively shortcoming of dispersive pressure.
The cushion pad that another kind occurs recently designs as shown in Figure 4, and cushion pad 41 comprises main body sheet 410 and many protruding 411 with back side projection from main body sheet 410 fronts; The end of each protruding grain 411 is made slick and sly moulding.Though such design makes cushion pad 41 easy stressed bendings and effectively dispersive pressure, but its shortcoming also is each protruding grain 411 and only links by the less main body sheet 410 of thickness each other, cause cushion pad 41 not only in vertical (shoulder belt trend) easy stressed bending but also in horizontal or oblique also all easy stressed bending, cause cushion pad 41 too to be easy to generate distortion and compression.Another shortcoming then is that the air-vent thereby the gas permeability of cushion pad 41 shortage up/down perforations is not good, then can further cause cushion pad 41 easier distortion and compressions if will set up air-vent.
The utility model content
The purpose of this utility model is to provide a kind of ventilative shoulder belt of knapsack with pooling feature, has the effect of good dispersive pressure but to be unlikely to twist too easily, has the high ventilation effect but to be not easy adsorption moisture.
For achieving the above object, the technical scheme that the utility model proposed is as follows:
A kind of ventilative shoulder belt of knapsack with pooling feature, comprise one section rectangular bag that is sewn into by tensile strength and the preferable cloth of gas permeability, be packed into the cushion pad that a length and width height roughly is equivalent to described rectangular bag inner space shape in the described rectangular bag with wide flat section; Described cushion pad comprises a main body sheet, forms a plurality of ribs that are approximately perpendicular to the shoulder belt trend on the described main body sheet, and each described rib comprises the first half that is formed on the described main body sheet front and the Lower Half that is formed on the described main body sheet back side; The described first half outer rim of each described rib and described Lower Half outer rim form a plurality of depressions respectively so that improve the easness that described rib produces distortion when stressed; Form the air-vent of a plurality of up/down perforations on the described main body sheet so that the hot gas that allows the toter of knapsack be distributed exchanges with the easy and extraneous fresh air of sweat steam on one's body.
One of advantage that the utility model brought is that the effect that can play good dispersive pressure but is unlikely to twist too easily.Its principle is that mainly the segment thickness of described rib is big so is not easy bending, then thickness is less so be easier to bending to be attached at described main body sheet between described rib and the rib, can roll into a ball and answer the big and less feature of the radian that bends right and left of shoulder crooked radian before and after the upper breast outside, the result is that described cushion pad can also keep maximum structural strength when sufficient docile performance is provided.
Another advantage that the utility model brought is can play the high ventilation effect but to be not easy adsorption moisture.Its principle is that mainly described cushion pad is not to adopt as many porosities materials such as spongy or flocculence, so be not easy adsorption moisture; Yet owing to the described air-vent total quantity more than enough (having tens at least) that is opened on the described main body sheet, each air-vent diameter is quite big (having several millimeters at least) again, the described Lower Half of adding described rib with described main body sheet from toter's body surface bed hedgehopping, form a plurality of groove shapes space, help flowing of air, therefore whole permeability is quite outstanding.
