The buffer spring can absorb the impact on the shoulder and back of the user caused by the ups and downs of the backpack, thus reduce the loading and protect the back and shoulders of the person.

Description

Cushioning backpack

The invention relates to backpacks, in particular to backpacks.

In the prior art, there is no cushion between the shoulder strap of the backpack and the backpack. The weight of the backpack and the vibration force of the ups and downs are directly transmitted to the user's shoulder through the shoulder strap, which is easy to fatigue.

The cushioning and shock-absorbing backpack includes a bag body and a shoulder strap of the backpack. A buffer spring is connected between the shoulder strap and the bag body, and the gravity of the bag body is transmitted to the shoulder strap through the buffer spring.

As a best embodiment, the buffer spring is installed in a box body, the box body is fixedly connected with the shoulder strap, the bag body is fixed with a support member, the support member extends into the box body and can slide up and down in the box body to support The member is supported on the top of the buffer spring, and the gravity of the bag body acts on the buffer spring through the support member, and then acts on the box body through the buffer spring and transmits it to the shoulder strap.

As a best embodiment, the portion of the shoulder strap that contacts the back of the human body is provided with a supporting foot that protrudes toward the back of the human body, and the portion of the body that contacts the back of the human body is also provided with a support foot that protrudes toward the back of the human body. The foot makes the space between the shoulder strap and the back of the human body, and the space between the bag body and the back of the human body empty, and forms an air flow through which air can flow.

As a best embodiment, an air cushion is fixed at the end of the support foot facing the back of the human body, and the air cushion is hemispherical.

As a preferred embodiment, a decompression strap is provided at a portion where the shoulder strap crosses the shoulder of the human body. When the user carries the backpack, the decompression strap is placed between the shoulder of the human body and the shoulder strap. With multiple arc springs, the decompression belt is supported by the arc shape of the arc spring in the thickness direction.

As a best embodiment, the other end of the arc spring is provided with a pulley, and the other end is fixed with a decompression belt.

The advantage of the present invention is that the buffer spring can absorb the impact force on the shoulders and back of the human body due to the up and down bumps of the body, reduce the gravity load on the back and shoulders of the user, and protect the back and shoulders of the user The role.

FIG. 1 is a schematic structural view of an embodiment of the present invention; FIG. 2 is an A-A cross-sectional view of FIG. 1; and FIG. 3 is an enlarged cross-sectional view of part B of FIG.

As shown in FIG. 1, a buffer shock-absorbing backpack provided according to the present invention includes a bag body 1 and a shoulder strap 2. A buffer spring 3 is connected between the upper end of the shoulder strap 2 and the bag body 1. When the user carries the backpack, the gravity of the bag body 1 is transmitted to the shoulder strap 2 through the buffer spring 3, thereby greatly reducing the impact force on the shoulders and back of the human body caused by the up and down movement of the bag body 1.

As a best embodiment, referring to FIGS. 1 and 2 at the same time, the buffer spring 3 is installed in a box 4. The box body 4 is fixedly connected to the shoulder strap 2 by riveting or screwing. The support body 5 is fixed to the package body 1 by riveting or screwing. The support 5 extends into the box 4 and can slide up and down in the box 4. The support 5 is supported on the top of the buffer spring 3. The buffer spring 3 is a compression spring, and its upper and lower ends are sleeved on a pin 6 respectively. The upper pin 6 is fixed on the support 5, and the lower pin 6 is fixed on the box 4. The pin 6 serves to stabilize the buffer spring 3. When the user carries the backpack, the gravity of the bag body 1 acts on the buffer spring 3 through the support 5, and then acts on the box body 4 through the buffer spring 3 and transmits it to the shoulder strap 2.

As a best embodiment, referring to FIG. 1, a portion of the shoulder strap 2 that contacts the back of the human body is provided with a supporting foot 7 that protrudes toward the back of the human body, and a portion of the body 1 that contacts the back of the human body is also provided with a support that protrudes toward the back of the human body. Foot 7. The support foot 7 makes the space between the shoulder strap 2 and the back of the human body, and the package body 1 and the back of the human body empty, forming an air flow through which air can flow, so that the back of the human body is well dissipated and the comfort of the backpack is improved.

Further, the end of the support foot 7 facing the back of the human body is fixed with an air cushion 8, thereby avoiding the discomfort caused by the hard support foot 7 pressing against the back of the human body. The optimal shape of the air cushion 8 is a hemisphere. As a best embodiment, referring to FIG. 1, a decompression strap 9 is provided at a portion of the shoulder strap 2 that straddles the shoulder of a human body. When the user carries the backpack, the decompression strap 9 is placed between the shoulder of the human body and the shoulder strap 2. The pressure relief strap 9 can be sewn and fixed under the shoulder strap 2 with a needle thread. Referring to FIG. 3, a plurality of arc springs 10 are provided inside the decompression belt 9, and the decompression belt 9 is supported by the arc shape of the elastic spring 10 in the thickness direction. When the pressure-relief strap 9 is pressed by the shoulder strap 2, the arc spring 10 stretches and deforms to cushion the pressure, so that it can relieve the pressure of the shoulder of the human body. As a further improvement, one end of the arc spring 10 is provided The pulley 11 has the other end fixed to the decompression belt 9. The pulley 11 can greatly reduce the friction between the end of the arc spring 10 and the decompression belt 9, so that the arc spring 10 can be stretched and deformed more smoothly, so that the impact of the shoulder strap 2 on the human shoulder can be more effectively absorbed force.

The above-mentioned embodiments only express several embodiments of the present invention, and their descriptions are more specific and detailed, but they should not be construed as limiting the scope of the invention patent. For those of ordinary skill in the art, without departing from the concept of the present invention, a number of modifications and improvements can be made, all of which fall within the protection scope of the present invention. The protection scope of the invention patent shall be subject to the appended claims.
