Description

Technical Field

[0001] This utility model relates to the technical field of backpack auxiliary products, and in particular to a silicone back plate for an auxiliary shoulder strap. Background Technology

[0002] The human back has a shape where the scapula and spine are convex at both ends and concave in the middle. The shape of the spine or the size of the spinal canal is not exactly the same for everyone, and there are individual differences. These differences are mainly the result of the combined effects of multiple factors such as genetic factors, lifestyle habits, age, gender, and the presence of certain diseases.

[0003] Therefore, the same model of backpack may not fit the spinal groove of different people, which may cause users to be unable to maintain a natural and healthy walking posture for a long time, such as causing users to hunch over. In addition, when the straps are hanging on the shoulders, they tend to slip off the shoulders due to the action of the trapezius muscles.

[0004] In view of this, the inventors specifically designed a silicone backplate for an auxiliary carrying strap, which led to this invention. Utility Model Content

[0005] The purpose of this invention is to provide a silicone backplate for an auxiliary carrying strap, which adapts to the spinal groove depth of different people by controlling the size of the airbag inflation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A silicone backplate for an auxiliary carrying strap includes a silicone main board, metal rings, and an airbag. The silicone main board has strip-shaped openings on its upper and lower sides for the metal rings to be inserted. An annular flange protrudes from the inner side of the silicone main board towards the center of the strip-shaped openings, providing a fixed position for the metal rings and preventing contact between the metal rings and the human body. The metal rings are respectively inserted into the strip-shaped openings and are fixedly connected to the outer sides of the silicone main board and the annular flange around the strip-shaped openings. The center of the metal rings and the annular flange allows the carrying strap to pass through. The airbag is embedded inside the silicone main board between the strip-shaped openings, and the airbag is used to prevent bending of the human spine. One end of the airbag extends outward through the silicone main board to form a locking part, which is used for the airbag to release gas and to facilitate the airbag being secured to the silicone main board.

[0008] Furthermore, a recess for embedding an airbag is provided on the inner side of the silicone main board between the strip-shaped openings; a snap-fit ​​hole for the airbag to pass through is provided on the silicone main board in the middle of the recess.

[0009] Furthermore, the airbag has a mushroom-shaped cross-section.

[0010] Furthermore, limiting blocks are respectively protruding between the strip-shaped opening and the upper and lower outer edges of the inner side of the silicone motherboard, and the silicone motherboard between the limiting blocks facilitates fitting the scapula.

[0011] Furthermore, the outer edge of the silicone motherboard is shaped like a butterfly wing.

[0012] Furthermore, the inner edge of the limiting block is located on the central axis of the strip-shaped opening.

[0013] Furthermore, the outer surface of the metal ring is located above the outer plane of the silicone motherboard.

[0014] After adopting the above technical solution, the present invention has the following beneficial effects:

[0015] This invention incorporates an airbag embedded inside the silicone mainboard and controls the airbag's inflation level to adapt to different spinal groove depths, allowing the backpack to better fit the back curves of various users, thus providing a more comfortable and healthy carrying experience. When the user bends over, the airbag is compressed more strongly, reducing its volume and increasing its reaction force, thereby promoting good walking posture. The shoulder straps enter through an upper strip opening on one side and exit through a lower strip opening on the same side, preventing them from slipping off the shoulder. Additionally, the outer side of the metal ring is located above the outer plane of the silicone mainboard, reducing friction between the shoulder straps and the silicone mainboard, minimizing wear and tear, and thus improving the durability of this invention.

[0025] Please see Figures 1 to 5 A silicone backplate for an auxiliary carrying strap includes a silicone main plate 1, metal rings 2, and an airbag 3. The silicone main plate 1 has strip-shaped openings 10 on its upper and lower sides for the metal rings 2 to be inserted. An annular flange 11 protrudes from the inner side of the silicone main plate 1 towards the center of the strip-shaped openings 10, providing a fixed position for the metal rings 2 and preventing contact between the metal rings 2 and the human body. The metal rings 2 are respectively inserted into the strip-shaped openings 10 and fixed to the outer sides of the silicone main plate 1 and the annular flange 11 around the strip-shaped openings 10. The metal ring 2 is fixed to the silicone main board 1 and the annular protrusion 11 around the strip opening 10 by adhesive. The middle of the metal ring 2 and the annular protrusion 11 is for the shoulder strap to pass through. The airbag 3 is embedded in the inner side of the silicone main board 1 between the strip openings 10. The airbag 3 is used to prevent the curvature of the human spine. One end of the airbag 3 passes outward through the silicone main board 1 to form a snap-fit ​​part 30. The snap-fit ​​part 30 is used for the airbag 3 to release gas and to make it easy for the airbag 3 to be snapped on the silicone main board 1. The snap-fit ​​part 30 is flip-top shaped and can be opened and closed.

[0026] like Figure 5 As shown, a recess 12 for inserting an air supply 3 is provided on the inner side of the silicone main board 1 between the strip-shaped openings 10; a snap-fit ​​hole 13 for the air supply 3 to pass through is provided on the silicone main board 1 in the middle of the recess 12, and the diameter of the snap-fit ​​hole 13 is smaller than the diameter of the snap-fit ​​part 30.

[0027] like Figure 4 As shown, the cross-section of airbag 3 is mushroom-shaped.

[0028] like Figure 3 As shown, a limiting block 14 is provided between the strip-shaped opening 10 and the upper and lower outer edges of the inner side of the silicone main board 1, respectively. The silicone main board 1 between the limiting blocks 14 can fit the scapula.

[0029] like Figure 1 As shown, the outer edge of the silicone motherboard 1 is shaped like a butterfly wing.

[0030] Preferably, the inner edge of the limiting block 14 is located on the central axis of the strip opening 10.

[0031] like Figure 1 As shown, the outer side of the metal ring 2 is located above the outer plane of the silicone motherboard 1. This structure is used to reduce friction between the strap and the silicone motherboard 1, thereby improving the durability of this invention.

[0032] The usage process of this utility model is as follows:

[0033] S1. The two shoulder straps of the backpack are inserted into the upper strip opening 10 on the outside of the silicone motherboard 1 and then exit from the lower strip opening 10 on the same side. The above structure is used to prevent the shoulder straps from slipping off the shoulder.

[0034] S2. After gas is introduced from the locking part 30, the system is sealed and the degree of inflation of the airbag 3 is controlled to adapt to the different spinal groove depths of different people.

[0035] The principle behind this invention in promoting healthy walking posture in users is as follows:

[0036] When the user bends over, the airbag 3 is compressed more strongly, reducing its volume and increasing its reaction force, thus helping the user maintain a good walking posture.

[0037] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
