TWI714004B - Shock cushioning backpack - Google Patents

Abstract

This invention discloses a shock absorption and cushioning backpack. A buffer spring is connected between the shoulder strap and the backpack. Weight of the backpack is transmitted to the shoulder strap through the buffer spring. 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 present invention relates to backpacks, in particular to backpacks.

In the prior art, there is no buffer between the shoulder strap of the backpack and the backpack, and the weight of the backpack and the vibration force of the up and down bumps are directly transmitted to the user's shoulders through the shoulder straps, which is easy to fatigue.

A 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 the best embodiment, the buffer spring is installed in a box body, the box body is fixedly connected with the shoulder strap, and 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 component is supported on the top end of the buffer spring, and the weight of the package body acts on the buffer spring through the support member, and then acts on the box body through the buffer spring and is transmitted to the shoulder strap.

As the best embodiment, a pressure relief belt is provided at the part where the shoulder strap straddles the shoulders of the human body. When the user carries the backpack, the pressure relief belt is cushioned between the shoulders of the human body and the shoulder belt. A plurality of arc springs, the pressure relief 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 pressure relief belt.

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

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

As shown in FIG. 1, a cushioning and shock-absorbing backpack provided by the present invention includes a bag body 1 and a shoulder strap 2. A cushion spring 3 is connected between the upper end of the shoulder strap 2 and the bag body 1. When the user picks up 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 shoulder and back of the human body due to the up and down bumps of the bag body 1.

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

Referring to FIG. 1, a pressure relief belt 9 is provided at the part of the shoulder strap 2 straddling the shoulder of the human body. When the user picks up the backpack, the pressure relief belt 9 is placed between the shoulder of the human body and the shoulder strap 2. The pressure relief belt 9 can be secured under the shoulder belt 2 by sewing with needles. Referring to FIG. 3, a plurality of arc springs 10 are arranged inside the pressure reducing belt 9, and the pressure reducing belt 9 is supported by the arc shape of the arc spring 10 in the thickness direction. When the pressure relief belt 9 receives the pressure of the shoulder strap 2, the arc spring 10 stretches and deforms to buffer the pressure, so as to relieve the pressure on the shoulders of the human body. As a further improvement, one end of the arc spring 10 is provided with The other end of the pulley 11 is fixed to the pressure relief belt 9. The pulley 11 can greatly reduce the friction between the end of the arc spring 10 and the pressure relief belt 9, so that the arc spring 10 can stretch and deform more smoothly, thereby more effectively absorbing the impact of the shoulder strap 2 on the human shoulder force.

The above-mentioned embodiments only express several embodiments of the present invention, and the descriptions are more specific and detailed, but they should not be understood 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, several modifications and improvements can be made, and these all fall within the protection scope of the present invention. The protection scope of the patent of the present invention shall be subject to the appended claims.
