Technical Field

The invention belongs to the technical field of shoulder strap devices, and particularly relates to an elastic supporting shoulder strap device which is applied to a backpack and can buffer the pressure of the backpack.

Background

The knapsack that the market is sold bears all is fixed plate type, does not accord with ergonomic design, and human vertebra bending line of laminating that can not be fine when knapsack weight aggravates like student's schoolbag is heavier, influences student's vertebra and grows, can lead to vertebra bending deformation when serious.

The novel backpack strap meets the natural curve of human spine by adopting the encircling design for carrying.

Disclosure of Invention

The invention aims to provide an elastic supporting strap device which is reasonable in structural design, adopts an encircling design for carrying, caters to the natural curve of the spine of a human body and can buffer carrying pressure, and aims to overcome the defects of the prior art.

The invention is realized by the following technical scheme: the elastic support braces device capable of buffering the bearing pressure comprises a braces body and is characterized in that a molding back plate is fixedly connected with the braces body; the lower side part of the forming backboard is fixedly provided with a soft binding waistband, and the upper side part of the forming backboard is fixedly provided with arc-shaped convex spongy cushion devices which are symmetrically arranged with each other through metal elastic pieces.

The metal elastic sheet is Z-shaped.

The arc-shaped convex spongy cushion device comprises PP back-rest plates which are symmetrically arranged and arc-shaped spongy cushions which are respectively fixed on the surfaces of the PP back-rest plates.

The number of the metal spring pieces is two and is set as one group, and the metal spring pieces can be set into more than multiple groups.

An arc waist pad is arranged between the soft binding waistband and the forming back plate.

The surface of the arc-shaped convex spongy cushion device is covered with a breathable net cover.

The back surface of the molding back plate is also provided with an aluminum alloy strip.

The invention has the beneficial effects that: compared with the prior art, the invention adopts the encircling design for the back bearing according to the ergonomic design, caters to the natural bending line of the vertebra of the human body, and utilizes the elasticity of one or more groups of metal elastic sheets to automatically adjust the stress direction depending on the posture change during the back bearing so as to form a dynamic buffer back-following feeling and share the pressure born by the back during the back bearing.

The arc-shaped convex spongy cushion device comprises PP back boards 8 which are symmetrically arranged and arc-shaped spongy cushions 3 which are respectively fixed on the surfaces of the PP back boards 8.

As shown in fig. 3, one end of the metal elastic sheet 7 is fixed on the PP back plate 8 through a screw, and the other end is fixed on the molding back plate through a screw; the metal spring sheet 7 is made of metal thin sheet, is easy to generate elastic deformation, and forces the backrest to have buffering back-tracing feeling when carrying heavy objects, thereby being capable of bearing the pressure born by the back when carrying the heavy objects.

The number of the metal spring pieces 7 is two, and the metal spring pieces are arranged into one group, and multiple groups can be arranged for use according to the size of the backpack.

As shown in fig. 2, an arc-shaped waist pad 6 is further arranged between the soft binding waistband 9 and the forming back plate 4, the arc-shaped waist pad 6 is filled with sponge and other materials, the arc-shaped waist pad 6 is matched with the waist curve of a human body, and the soft binding waistband is suitable for actions such as bending down and walking to bring comfort. The soft binding belt 9 is adhered by a magic tape or two free ends are mutually lapped by movable buttons.

The upper cover of the surface of the arc-shaped convex spongy cushion device is provided with a breathable net cover, so that back sultry is avoided when the device is carried on the back, and meanwhile, the device also plays a role in preventing the arc-shaped spongy cushion 3 from being scratched.

The back surface of the molding back plate 4 is also provided with an aluminum alloy strip 5; the rectangular 5 of aluminum alloy is fixed on the reverse side of shaping backplate 4 through consolidating the screw, and rectangular 5 further consolidations of aluminum alloy support design knapsack to avoid the knapsack pincher trees, crooked, also play the additional effect to shaping backplate 4's design simultaneously.

The above description of the embodiments is only intended to facilitate the understanding of the method of the invention and its core idea. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
