Description

KNPSACK TO REDUCE A PRESSION}

The present invention relates to a compression relief backpack, and more specifically, the backpack back, shoulder suspenders, and air cushions installed at the bottom of the backpack reduce the pressure on the shoulders and back when carrying the backpack on the shoulders, thereby reducing fatigue. The present invention relates to a pressure-relieving backpack that can protect the contents contained from external impact while preventing it from falling or falling over.

In general, a backpack is provided with a main body that can hold the contents, and a shoulder suspender that can be connected to the main body to carry on the shoulder. In the shoulder suspenders, a sponge or a nonwoven fabric was inserted into the backrest and shoulder suspenders so that a person does not feel the weight of the backpack heavily when carrying the backpack.

In order to prevent the contents of the backpack from sagging under the backpack, a thin synthetic resin board or a thick paper board was placed on the bottom of the backpack.

However, the conventional backpack is used by inserting a sponge or a non-woven fabric, and if used for a long time, the sponge or non-woven fabric becomes thin and the bottom of the backpack sags to be unsightly. The contents of the inner wobbly inconvenient to run, there was a disadvantage to stab or press the back when carrying a hard or sharp object in the backpack.

The present invention has been made to solve the conventional problems, by inserting the air cushion in the back of the backpack and shoulder straps and the bottom of the backpack to prevent the contents of the backpack to fall or fall, maintaining a constant distance between the backpack and the back of the person The present invention provides a compression relief backpack that protects a person's back from the contents of the backpack and prevents excessive pressure or load on the shoulder due to the weight of the backpack.

An air cushion with an air inlet formed in the back of the backpack is inserted between the lining and the outer surface of the backrest, divided into equal lengths and sewn to the first air cushion, and the air cushion with the air inlet formed on the shoulder suspenders. The second air cushion inserted between the outer and outer shell, and the third air cushion is inserted into the bottom and both sides of the backpack of the air cushion having an air inlet formed on the bottom of the backpack.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of a state installed the air cushion of the present invention, Figure 2 is a longitudinal sectional view showing a state installed the air cushion of the present invention, Figure 3 is a perspective cross-sectional view showing an air injection state of the present invention.

The pressure-relieving backpack has a relatively deep accommodation space, and is provided with a main body that artificially opens the accommodation space according to the will, and a shoulder suspender coupled to the outside of the back of the main body.

The first air cushion 10 inserts an air cushion having an air inlet 14 through which air can be injected between the outer shell 13 and the lining 12 of the backrest 15.

The first air cushion 10 is equally divided into a predetermined length capable of supporting a width and a back of about 2/3 of the backrest and is sewn together with the backrest 15.

The first air cushion 10 may be implemented to match the size of the backrest 15.

The air inlet 15 forms a lid 14a to prevent the air introduced into the air cushion from leaking out, and is preferably installed at an upper side of the backpack back.

The second air cushion 20 has an air inlet 24 for injecting air between the lining 22 and the outer fabric 23 of the shoulder suspenders 25, and the air cushion for entering the air at predetermined intervals. Stitch the insert into the shoulder suspenders (25).

The air inlet 24 is preferably formed in the center portion of the shoulder suspenders (26).

The third air cushion 30 inserts an air cushion having an air inlet 34 through which the air can be injected between the lining 32 and the outer fabric 33 of the backpack bottom 35 and has a predetermined height on both sides of the backpack. By inserting the air cushion as one body, it is sewn to prevent the contents from falling to the side.

The air inlets 14, 24 and 34 are combined with the air cushion to expose the outside of the outer shell 13, 23, 33 of the backpack to facilitate the air injection using the pump 16 or the like. In addition, the air inlet (14, 24, 34) forms a lid 14a to prevent the air from leaking out to enable the opening and closing.

It is preferable that the material of said 1st, 2nd, 3rd air cushion is polyvinyl chloride (PVC), vinyl-type resin, etc.

As shown in FIG. 3, the lid 14a of the air inlets 14, 24, and 34 is formed by using the pump 16 or the like in the first air cushion 10, the second air cushion 20, and the third air cushion 30. Open and open) to inject air.

When the backpack is used while the air is injected into each air cushion 10, 20, 30 using the pump 16, etc., the floor air cushion 30 keeps the backpack bottom 35 flat and the contents. Do not allow (M) to fall or fall, and the air cushion is inserted into the side of the bottom of the pack to prevent the contents (M) from falling to the side, and from external shock when carrying or Protect the contents of the backpack.

The first air cushion 10 maintains a predetermined distance between the contents of the backpack and the back of a person, thereby preventing the contents M from being pierced or pressed from a hard or sharp object, and the second air cushion 20. The pack contains a lot of backpack contents (M) to prevent the shoulder straps from squeezing or compressing the shoulders when the backpack is heavy.

The present invention as described above, the bottom of the backpack is kept flat without falling down, so that the contents do not fall or fall, the air cushion is integrally inserted into the side of the backpack bottom, so that the contents do not fall or fall to the side, It is convenient to wear the backpack because it does not sag or moves.It protects the contents of the backpack from external shocks, and an air cushion is inserted into the backrest to maintain a certain distance between the backpack and the person's back. It is effective in preventing the shoulder straps from squeezing or compressing the shoulders when the backpack is heavy.
