Abstract
Description
[Technical field]
[0001] The present invention relates to a backpack, and more particularly to a shock-absorbing and load-relieving backpack. [Background technology]
[0002] Currently, various load-reducing backpacks are available on the market, and they usually achieve the load-reducing effect by attaching elastic members to the shoulder straps or backrest. For example, a utility model with registration publication number CN207514542U discloses a backpack load-reducing device. The device includes a backpack with openwork on the backrest, a back plate that is connected to the periphery of the backpack to form an enclosed space, and shoulder straps. The lower end of the shoulder strap is connected to the back plate, and the upper end is connected to a spring damping mechanism provided on the inside of the back plate via the back plate. The spring damping mechanism can provide a phase difference between the vibration of the backpack weight and the vibration of the human body when the human body walks with a load, thereby reducing the weight pressure received by the trunk of the human body. However, this backpack has two independent shoulder straps that are not integrated by a connecting member, so that if there is a difference in the left and right shoulders or if a user with poor backpack habits is encountered, the problem of uneven force reception of the two shoulder straps during use occurs. As a result, most of the backpack's weight is carried by a single shoulder strap, affecting the user's experience. Summary of the Invention
[0003] The problem that the present invention aims to solve is to provide a backpack that cushions and reduces the load, and allows the shoulder straps used by the user to bear the load evenly and with a small swing range.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A shock-absorbing and load-relieving backpack includes a backpack body, a backrest provided on the back of the backpack body, and two shoulder straps provided on the backpack body. A spring and a T-shaped stopper plate are provided between the backpack body and the backrest. The T-shaped stopper plate includes a connection part and stoppers provided on both sides of the connection part. A first connection hole and a second connection hole are provided on the connection part. One end of the shoulder strap is connected to the first connection hole, and the other end is fixedly connected to the backpack body. The first connection hole is provided on the upper part of the T-shaped stopper plate, and the second connection hole is provided on the lower part of the T-shaped stopper plate. One end of the spring is connected to the second connection hole, and the other end is connected to the backpack body. Both sides of the tip of the backrest are provided with a stitching area, a passage is provided between the stitching areas, and the stopper part corresponds to the stitching area. The principle of the present invention is as follows. The T-shaped stopper plate design balances the load of the two shoulder belts. The spring acts as a stopper against the stopper plate, reducing the swing of the shoulder belt and providing a vibration damping effect. At the same time, the elasticity of the spring also plays a role in reducing the load, optimizing the user experience.
[0005] Preferably, the two shoulder belts correspond to two first connecting holes, and the two first connecting holes are symmetrically provided on the connecting portion.
[0006] Preferably, an upper end of the connecting portion protrudes from the passage.
[0007] Preferably, the backrest is provided with a support pad.
[0008] Preferably, the connection portion is provided with a third connection hole and a stopper belt that limits its movement stroke, the third connection hole is provided between the first connection hole and the second connection hole, one end of the stopper belt passes through the third connection hole and is connected to a T-shaped stopper plate, and the other end of the stopper belt is fixed to the backpack body.
[0009] Preferably, a connection unit is provided on the backpack body, and the spring is fixedly connected to the backpack body by the connection unit.
[0010] Preferably, the connection unit includes a connection belt fixed to the back surface of the backpack body, and a connection plate connected to the connection belt, both ends of the connection belt are fixed to the same position on the backpack body, and the connection belt forms a buckle, and the connection plate penetrates the buckle and protrudes from both ends of the buckle.
[0011] Preferably, two fourth connection holes are provided on the connecting plate, the two fourth connection holes are respectively provided on both sides of the connecting belt, the lower ends of the springs are connected to the connecting plate through the fourth connection holes, the two fourth connection holes correspond to the two springs, the two springs correspond to the two second connection holes, and the two second connection holes are symmetrical to each other.
[0012] The beneficial effects of the present invention are as follows: By providing a T-shaped stopper plate to connect two springs and two shoulder straps together, the problem of uneven force reception by the user due to issues such as left and right shoulder difference during use can be avoided. At the same time, the stopper parts on both sides of the T-shaped stopper plate and the unstitched area of the backrest control the lateral movement of the T-shaped stopper plate, and the stopper belt controls the vertical movement of the T-shaped stopper plate. This prevents the shoulder strap from being greatly shaken due to the swinging of the backpack body during use by the user, and exerts a buffering effect. The elasticity of the spring can also exert a certain burden reduction effect on the user. The upper end of the shoulder strap can move within the first connecting hole, and the shoulder strap can be adjusted to an appropriate position for users with different body types, improving the user experience. [Brief description of the drawings]
[0013] [Figure 1] FIG. [Diagram 2] FIG. 2 is a schematic diagram of the rear structure of the present invention after the backrest is hidden. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES
[0014] The present invention will now be described in more detail with reference to the accompanying drawings of the specification.
[0015] As shown in Figures 1 and 2, this is a shock-absorbing and load-relieving backpack, which comprises a backpack body 1 and two shoulder straps 8 attached to the backpack body 1. A backrest 2 is provided on the underside of the backpack body 1, and a support pad 21 is provided on the backrest 2. The support pad 21 can provide a certain level of support for the user's back when used by the user, and has the functions of preventing hunchback and massaging. Stitched areas are provided on both sides of the tip of the backrest 2, and an unstitched passage is provided between the stitched areas.
[0016] As shown in Figs. 1 and 2, an elastic member and a T-shaped stopper plate 3 connected to the elastic member are provided on the back surface of the backpack body 1. The elastic member and the T-shaped stopper plate 3 are provided between the backpack body 1 and the backrest 2. The elastic member is a spring 4, and the number of springs 4 is two. The T-shaped stopper plate 3 includes a connection portion 35 and stopper portions 34 symmetrically arranged on both sides of the connection portion 35, and the stopper portions 34 are provided in the lower portion of the connection portion 35. The connection portion 35 is provided with a stopper belt 6 that limits its movement stroke. The connection portion 35 is provided with a first connection hole 31 to which a shoulder belt 8 is connected, a second connection hole 32 to which the spring 4 is connected, and a third connection hole 33 to which the stopper belt 6 is connected. The first connection hole 31 is provided in the upper portion of the connection portion 35, and the two shoulder belts 8 correspond to the two first connection holes 31. The lower end of the shoulder belt 88 is fixed to the backpack body 1, and a belt loop 81 is provided at the upper end of the shoulder belt 8. The belt loop 81 is connected to the T-shaped stopper plate 3 through the first connection hole 31, and the belt loop 81 is movable within the first connection hole 31, and the two shoulder belts 8 can be expanded outward or retracted inward. It can be automatically adjusted to an appropriate position for users of different body types, and the user experience can be improved. The second connection hole 32 is provided at the lower part of the connection part 35, and two springs 4 correspond to the two second connection holes 32. The upper end of the spring 4 is connected to the T-shaped stopper plate 3 through the second connection hole 32, and a connection unit body is provided at the lower end of the spring 4. The lower end of the spring 4 is connected to the backpack body 1 through the connection unit. The connection unit includes a connection belt 7 fixed to the backpack body 1 and a connection plate 5 provided on the connection belt 7. Both ends of the connection belt 7 are fixed to the same position of the backpack body 1, and the connection belt 7 forms a loop buckle. A connecting plate 5 is fitted into the ring buckle, and the connecting plate 5 penetrates the ring buckle and protrudes from both ends of the ring buckle. Fourth connecting holes 51 that connect to the springs 4 are provided on both sides of the connecting plate 5, and the fourth connecting holes 51 are provided on both sides of the connecting belt 7. The lower end of the spring 4 is connected to the connecting plate 5 through the fourth connecting hole 51.The upper end of the stopper belt 6 is connected to the T-shaped stopper plate 3 through the third connecting hole 33, and the lower end of the stopper belt 6 is fixed to the backpack body 1. The stopper belt 6 and the connecting belt 7 are fixed at the same position of the backpack body 1. The design of the stopper belt 6 prevents the T-shaped stopper plate 3 from moving excessively in the longitudinal direction, and acts as a stopper for the T-shaped stopper plate 3, and avoids affecting the elasticity of the spring 4 due to the excessive tension of the spring 4. In addition, the T-shaped stopper plate 3 works in conjunction with the spring 4, so that the shoulder force is more uniform when the user uses it. The upper end of the T-shaped stopper plate 3 protrudes from the passage, and stopper parts 34 are provided on both sides of the T-shaped stopper plate 3 to prevent the T-shaped stopper plate 3 from completely passing through the passage. The stopper parts 34 are integrally molded with the T-shaped stopper plate 3. The joint action of the stitched area and the stopper portion 34 prevents the T-shaped stopper plate 3 from completely coming out of the passage and controls the tension length of the spring 4, preventing the spring 4 from being destroyed by excessive tension and preventing damage to the entire backpack body 1. The shoulder belts 8 are disposed on the outside of the backrest 2 and connected to the T-shaped stopper plate 3, preventing the T-shaped stopper plate 3 from falling to the left or right and allowing the T-shaped stopper plate 3 to always be kept upright.
[0017] The principle of use of this invention is as follows. By indirectly connecting two shoulder belts 8 with the T-shaped stopper plate 3, the stopper belt 6 controls the longitudinal movement of the T-shaped stopper plate 3, and the stopper part 34 on the T-shaped stopper plate 3 and the stitching area at the tip of the backrest 2 control the lateral movement of the T-shaped stopper plate 3. The force is more uniform when the user is using the bag, and excessive pressure is avoided on one shoulder belt 8 due to the problem of the difference between the left and right shoulders. In addition, the backpack body 1 does not move the shoulder belt 8 and shake it excessively, and the purpose of buffering can be achieved. At the same time, the elasticity of the spring 4 can also achieve the effect of reducing the burden on the user. [Explanation of symbols]
