Abstract

A kind of knapsack straps, including base band, the base band is at least provided with the decompression piece of width 3 ~ 5cm bigger than baseband width in the position of corresponding shoulders of human body, the decompression piece includes metal shaping loop and buffer layer, and it is wrapped up by PU leather on the outside of metal shaping loop and buffer layer, the metal shaping loop is the globoidal structure for being bonded shoulders of human body, and buffer layer includes substrate and functional layer, the substrate lateral surface is fitting human body face, it is lining in functional layer and metal shaping loop lower part, including the polypropylene fibre tissue layer stacked gradually and foamed cotton layer, and outermost layer and innermost layer are polypropylene fibre tissue layer；And the functional layer includes wire side holder and is molded over the elastic polyurethane bed course of wire side stent inner surface, which is PE holders or PVC holders, takes on dress metal shaping loop and is connected therewith.The utility model can effectively improve the comfort level of shoulder when knapsack bears a heavy burden.

Description

A kind of knapsack straps

Technical field

The utility model is related to portable luggage technical field, specially a kind of shoulder that can effectively reduce strangles pressure sensitivity Knapsack straps.

Background technology

As common personal effects, Elementary Function student is used for holding study article knapsack as school bag, and learns The raw most time in school will also be contacted with school bag.With the quickening of living and studying rhythm, knapsack is not Be again it is simple hold books and stationery, other personal effects being also used to including containing clothes, computer, pattern and function Also increased, capacity is also designed increasing, and these also result in the increase of backpack weight.

As the critical piece on knapsack, knapsack straps generally using mostly use nylon or polyester fiber be made it is hollow band-like Structure, then by foam material seam be woven in the cavity of hollow banded structure, although this material using soft foam material come Realize buffering, but still material is harder, and smaller with the contact area of shoulder, with upper and lower fluctuating of walking, book strap still can It constantly ties tight and the shoulder that rubs, shoulder is caused to receive extruding, cause shoulder tired due to pressure, and with the increasing of backpack weight Add, this extruding force is also easy to cause user's shoulder red and swollen, or even cause at shoulder neck and clavicle skin abrasion or Cause skin allergy.

Utility model content

The technical issues of the utility model is solved is to provide a kind of knapsack straps, to solve in above-mentioned background technology Disadvantage.

The technical issues of the utility model is solved is realized using following technical scheme：

A kind of knapsack straps, including base band, the base band are at least provided with decompression piece, institute in the position of corresponding shoulders of human body It is bigger 3 ~ 5cm than baseband width to state decompression piece width, including metal shaping loop and buffer layer, and in metal shaping loop and buffer layer Outside is wrapped up by PU leather, and the metal shaping loop is to be bonded the globoidal structure of shoulders of human body, and buffer layer includes substrate And functional layer, the substrate lateral surface are fitting human body face, are lining in functional layer and metal shaping loop lower part, including layer successively Folded polypropylene fibre tissue layer and foamed cotton layer, and outermost layer and innermost layer are polypropylene fibre tissue layer；And the work( Ergosphere includes wire side holder and is molded over the elastic polyurethane bed course of wire side stent inner surface, the wire side holder be PE holders or Person's PVC holders are taken loaded on being connected on metal shaping loop and therewith.

In the present invention, the decompression piece is detachable structure in base band, by velcro in base band medial surface Upper carry out adhesion.

In the present invention, the metal shaping loop outer layer covers have EVA resin.

In the present invention, the setting number of plies of the foamed cotton layer is preferably two layers, foamed cotton layer and polypropylene fibre fabric The ratio between thickness of layer is 3:1, and the sum of thickness of foamed cotton layer is 3 ~ 5mm.

In the present invention, it is evenly arranged with air hole on the buffer layer level and PU leather leather surfaces.

In the present invention, the elastic polyurethane cushion thickness is 5 ~ 8mm.

In the present invention, it is tired to alleviate shoulder to be also uniformly fixed with physical therapy magnetic sheet for the elastic polyurethane mat surface Labor.

Advantageous effect：The utility model by base band be arranged decompression piece come to shoulder into row buffering, the patch with human body Close property it is more preferable, and have preferable cushioning effect, human body can both have been protected when being impacted, at the same also can knapsack just Ensure comfort level when often bearing a heavy burden.

Description of the drawings

Fig. 1 is the schematic cross-section of the utility model preferred embodiment.

Wherein：1, base band；2, velcro；3, PU is removed from office；4, wire side holder；5, elastic polyurethane bed course；6, physical therapy magnetic sheet；7、 Polypropylene fibre tissue layer；8, foamed cotton layer；9, EVA resin；10, metal shaping loop.

Specific implementation mode

In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under Face combines and is specifically illustrating, and the utility model is expanded on further.

Referring to a kind of preferred embodiment of knapsack straps of Fig. 1, in the present embodiment, schoolbag brace includes base band 1, the base It is sewed with velcro 2 on the inner surface of corresponding shoulders of human body position with 1, and adhesion, institute are carried out to decompression piece by velcro 2 It is bigger 4cm than baseband width to state decompression piece width, and adhesion is carried out by velcro 2 and base band 1 in centre position.

The profile of entire decompression piece is the globoidal structure of shoulders of human body, and outer layer is wrapped up by PU leather 3, and logical in outer rim Metal shaping loop 10 is crossed to carry out shaping, meanwhile, functional layer is filled in metal shaping loop 10, which includes wire side holder 4 and it is molded over the elastic polyurethane bed course 5 of 4 inner surface of wire side holder, wire side holder 4 is PVC holders, and edge is taken mounted in gold Belong on shaping loop 10 and be connected therewith, while to provide buffer protection to metal shaping loop 10 and ensureing the stabilization of wire side holder 4 Property, there is EVA resin 9 in 10 outer layer covers of metal shaping loop.Elastic polyurethane bed course 5 is uniformly between filling completely metal shaping loop 10 Space, and be uniformly fixed on the lower surface thereof physical therapy magnetic sheet 6 come alleviate toter shoulder fatigue.

In addition, decompression piece is also lined with one layer of lining under metal shaping loop 10 and elastic polyurethane bed course 5 and physical therapy magnetic sheet 6 Bottom, the substrate lateral surface are fitting human body face, including the three-layer polypropylene fiber fabric layer 7 stacked gradually and two layers of foamed cotton layer 8, wherein the ratio between foamed cotton layer 8 and the thickness of polypropylene fibre tissue layer 7 are 3:1, and the sum of the thickness of two layers of foamed cotton layer 8 is 4mm。

Meanwhile it in order to improve the permeability of entire decompression lamella, removing from office in buffer layer level and PU and being uniformly arranged on 3 leather surfaces There is air hole.
