Description

The present invention relates to a back assisting device that is provided between the back side and the back of the lower end of the backpack when carrying the backpack and distributes the weight of the backpack over the shoulder and back.

In the conventional device, a pressing spring is sandwiched between the back and the vicinity of the lower end of the rucksack so as not to get mud. Even though it was a spring-like part that hits the back, it hit the body, so it was hard for people who were thin or have weak skin. In addition, for the purpose of preventing stuffiness, the weight of the rucksack was firmly received and the body was not shaped to escape (Patent Document 1).
Moreover, although there is a thing which sandwiches a spacer between the human body to prevent it from becoming easily stuffy when carrying a rucksack, it has a shape only for providing a gap. (Patent Document 2)

JP 2015-29728 A JP 2004-329801 A

Although a device for opening a space between the back and the backpack was devised, it was intended to prevent stuffiness. Although there were many people who felt heavy on their shoulders when carrying heavy equipment on their backs or carrying them for a long time, none of them were designed to reduce weight. The use of push springs and spacers only required coolness, and some springs were exposed, making them unsuitable for people with weak bodies or long-term use.
The present invention provides an assisting device for a backpack that eliminates them and distributes the weight of the backpack on the shoulder and back to reduce the burden on the shoulder.

Provided between the back side of the lower end of the backpack and the back with the backpack carried on the back. An assisting device for a backpack comprising a surface along the back, wherein the surface along the back is formed into a curved surface having a shape corresponding to the shape of the back.

A support device for a backpack characterized by comprising a surface along the backpack.

An assisting device for a backpack characterized in that the distance between the surface along the back and the surface along the backpack narrows from below to above.

An assisting device for a backpack characterized in that one of the surfaces orthogonal to the surface along the back is formed into a curved surface having a shape corresponding to the shape of the back.

An assisting device for a backpack characterized in that an interval between the one surface and the surface facing the one surface becomes narrower from one side to the other side.

An auxiliary tool for a backpack characterized by being able to inflate with air.

An assisting device for a backpack characterized by providing a space so that small items can be inserted therein.

An auxiliary tool for a backpack characterized by having a non-slip function on the surface.

A backpack characterized by comprising a backpack auxiliary tool mounted near the back side of the lower end of the backpack.

The weight of the backpack is transmitted to the back via the back support tool by sandwiching the back support tool between the back side and the back of the back of the back tool with the back tool in the back. The weight of the backpack can be distributed to the shoulders and back. By providing a surface along the back, the back can be fitted to the back without any sense of incongruity, more weight can be received and escaped to the back, and the weight on the shoulder can be reduced, so the burden on the shoulder can be reduced.

By providing a surface along the backpack on the backpack auxiliary equipment, the weight of the backpack can be more easily received, the weight of the backpack can be distributed to the back, and the pain of the shoulder can be reduced.

As the distance between the surface along the back and the surface along the backpack narrows from below to above, the upper part of the backpack tilts toward the body and the lower part leaves the body. Thereby, the back of the backpack is prevented from being bent, and the shoulder strap is not pulled back and can be easily carried on the back. By tilting the backpack, the weight of the backpack can be easily transmitted to the back via the backpack auxiliary equipment, and the weight of the backpack can be distributed between the shoulder and the back, reducing the painfulness of the shoulder.

By making one of the surfaces perpendicular to the surface along the back into a curved surface corresponding to the shape of the back, the distance between the back and the back side of the lower end of the backpack is narrow even on the wider side. Can also change. In order to widen the gap, the surface along the back is placed against the back while the wide surface of the auxiliary device of the backpack is horizontal, and the upper part of the backpack is sandwiched so that it leans toward the body. By doing so, the angle at which the upper part of the backpack tilts toward the body increases, and the proportion of the weight applied to the back support equipment and the back also increases. Also, if the back of the assistive device of the backpack is leveled, the surface along the back is placed against the back, and the surface is changed so that the upper part of the backpack is tilted toward the body, the tilt of the backpack will be reduced. , Reduce the weight on the back. In this way, the surface to be applied to the back can be properly used depending on the weight of the backpack and the comfort of the backpack.

If the distance between the one surface and the surface facing the one surface is narrowed from one side to the other, two sets of surfaces along the back and surfaces along the backpack can be made. In order to narrow or widen the gap between the back side of the back and the lower end portion of the backpack, the horizontal surface can be selected depending on whether it is narrow or wide. The inclination of the backpack changes with the difference in the distance, and the weight of the backpack distributed on the back also changes. Depending on the weight of the backpack at that time, you can choose the spacing according to your back comfort and your preference.

By making it an auxiliary tool for a backpack characterized by being able to inflate and inflate, it can be inflated when necessary, and can be carried out compactly when not in use.

While maintaining the shape and maintaining the strength to receive the weight of the backpack, providing a space in the backpack auxiliary tool is convenient because it can store small items such as umbrellas, wallets and towels in place of the pochette.

By providing an anti-slip function on the surface of the assisting device of the backpack, the back of the clothes and the backpack can be prevented from slipping, making it easier to receive the weight of the backpack. If the surface of the assisting device of the backpack is slippery, it is effective because the weight tends to escape.

Since the auxiliary tool of the backpack is mounted from the beginning near the back side of the lower end of the backpack, the weight of the backpack can be released to the back, and the weight of the backpack can be distributed to the shoulder and back. In addition, the appearance is simple, and it is not necessary to attach an auxiliary tool for the backpack with the mounting tool.

Example in which auxiliary equipment of backpack was mounted in the vicinity of the lower end portion of the backpack from the beginning 13-1 Example of the back from the side contacting the back of the backpack 13-2 Example of the back of the back An embodiment in which an auxiliary device for a backpack is attached to a waist belt and arranged on the back side. Example in which a space is provided in the back while maintaining the shape and strength of the assistive device An embodiment in which the assisting device of the backpack has a shape other than a rectangular parallelepiped (an embodiment having a surface along the back and a surface along the backpack, but being constricted during that time) Side view of attaching a belt to the assistive device of the backpack and attaching a projection to the back of the backpack

The assisting device 1 of the backpack is substantially a rectangular parallelepiped, and has a curved surface shaped along the back and a surface along the backpack 8 (FIGS. 1 and 5), and the back side of the lower end of the backpack 8 and the back side of the back. It can be sandwiched between them (FIGS. 10 and 11).

A mounting tool 2 is provided around the center of both side surfaces (C surface, C ′ surface) of the auxiliary tool 1 of the backpack (FIG. 9). Both sides are attached to the lower end of the shoulder strap 5 of the backpack 8 with the mounting tool 2 (FIG. 12-12), and the auxiliary tool 1 of the backpack is sandwiched between the back side of the lower end of the backpack 8 and the back. (Figs. 10 and 11). When the cover 3 is attached to the entire surface of the auxiliary tool 1 of the backpack (FIG. 9), it can be removed and washed when it becomes dirty with mud or sweat and can be used hygienically. The attachment 2 may be attached to the cover 3 as well as directly attached to the auxiliary tool 1 of the backpack, or may be attached through the auxiliary equipment 1 of the backpack.

In the case of the first embodiment shown in FIG. 1, an A surface and an A ′ surface facing each other, a B surface and a B ′ surface facing each other, and a C surface and a C ′ surface facing each other are provided.
The A surface is the widest surface and is formed into a curved surface along the shape of the back, and the A ′ surface is formed into a shape along the backpack 8. When the A surface is applied to the back, the B surface is the upper surface and the B ′ surface is the lower surface. The C plane and the C ′ plane are the side surfaces of the A plane and the A ′ plane.
The A surface is a curved surface that is recessed so that the center portion matches the shape of the back rather than the left and right end portions.
The A ′ surface along the backpack 8 does not warp when the backpack 8 is carried on the back, and is in a posture that the upper part of the backpack 8 is inclined toward the body and the lower part is separated from the body. For this reason, the distance between the A surface along the back and the A ′ surface along the backpack becomes narrower from the lower side to the upper side, so the C and C ′ surfaces are also narrowed toward the upper side. It is a shape.

The second embodiment shown in FIG. 5 includes an A surface and an A ′ surface facing each other, a B surface and a B ′ surface facing each other, and a C surface and a C ′ surface facing each other. For the second embodiment, in the curved surface B is along the back, B 'plane has a plane along a backpack device 8, as in FIG. 10, A plane and A' If you plan to use in surface As shown in FIG. 11, two sets of surfaces along the back and surfaces along the backpack 9 when facing the B surface and the B ′ surface are opposed to each other.
Side a is longer than side b. The side b ′ is longer than the side b.
The usage method is as a first usage example (FIG. 10), with the A surface of the assisting device 1 of the backpack along the back, the A ′ surface along the backpack 8, and the backpack 8 being carried on the back. The backpack 8 is inclined so that the weight of the backpack 8 is applied to the back through the auxiliary equipment 1 of the backpack, the weight applied to the shoulder is reduced, and the back and weight are dispersed.
Further, as a second usage example (FIG. 11), when the B surface is placed along the back and the wide A surface is sandwiched horizontally, the distance between the back side of the lower end portion of the backpack 8 and the back is as follows. It becomes wider than the usage example 1 (FIG. 10). Therefore, the inclination of the backpack 8 is larger than that in the first embodiment of FIG. 1, and the weight of the backpack 8 is easily applied to the B surface, and the weight is dispersed by the back. The second embodiment can be used in either the first usage example (FIG. 10) or the second usage example (FIG. 11).
In this way, whether or not the distance between the lower end portion of the backpack 8 and the back can be determined by selecting the surface, and the comfort of the backpack 8 can be obtained.

The surface along the back of the auxiliary tool 1 of the backpack is applied to the back. At that time, the surface along the opposing backpack 8 is along the vicinity of the back side of the lower end of the backpack 8, and the back of the backpack 8 is inclined to the body side, and the lower part is separated and has an oblique posture. Therefore, the distance between the backpack 8 and the back becomes narrower from below to above.

The material of the auxiliary tool 1 for the backpack has a strength to receive the weight of the backpack 8 and is a lightweight material such as polystyrene foam, sponge, plastic, or resin. From the viewpoint of lightness and hardness, polystyrene foam is preferred.

In the case of the first embodiment, there is only one set in which the surface along the back and the surface along the back device that is slanted so that the back device 8 is inclined are the second embodiment. In the case of, there are two sets, but if you use other aspects, you can also have three sets. In the case of two sets or three sets, the inclination of the backpack 8 increases as the plane between the backpack 8 and the back is horizontally sandwiched horizontally (FIG. 11). The greater the inclination, the greater the proportion of weight on the part that hits the back, and the lower the burden on the shoulder. It is advisable to select the surface of the assisting device 1 of the backpack that creates the space between the backpack 8 and the back according to his / her preference and select which surface is easy to touch the back.

When using the auxiliary tool 1 of the backpack, the mounting tool 2 can be attached to the center of both side surfaces (FIG. 9). In that case, if the part of the attachment 2 is made of rubber or the like so that it can be slightly expanded and contracted, the surface of the assisting device 1 of the backpack will be changed in order to change the distance between the back and the lower end of the backpack 8. Easy to expand and contract. By attaching the attachment 2, the auxiliary tool 1 for the backpack can be easily attached to and detached from the lower end portion of the shoulder strap 5 of the backpack 8. When the auxiliary tool 1 of the backpack is unnecessary, it can be easily removed and is convenient.

If the shape of the auxiliary tool 1 of the backpack can be maintained, it is convenient to carry it because it can be compact when not in use if it can be taken in and out and can be folded. When inflating with air, it may be made of a vinyl or rubber material capable of retaining the strength of receiving the weight of the backpack 8.

If the shape of the assisting device 1 for the backpack and the strength of receiving the weight of the backpack 8 can be maintained and the weight is light, a space 10 is provided in the assisting device 1 for the backpack as shown in FIG. It is also possible to allow small items such as towels to enter. It is convenient to attach and remove a chuck etc. to the cover.

If the anti-slip 4 or the like is wrapped or pasted on the surface of the auxiliary device 1 or the cover 3 of the backpack (FIG. 9), the back clothing or the backpack 8 will not slip, and the backpack 8 will be more effective. Can be received on the back through the auxiliary tool 1 of the backpack. The anti-slip 4 is not slippery if a silicon sheet or vinyl chloride resin having an unevenness such as an anti-slip under the mat is used, but other materials and methods may be used as long as they have an anti-slip effect.

12-2 of FIG. 12, without attaching the attachment tool 2 to the auxiliary tool 1 of the backpack, the stretchable net 7 is stretched on the back side of the lower end portion of the backpack 8, and the auxiliary tool 1 of the backpack is placed there. It can also be inserted. In addition, as long as the weight of the backpack 8 is easily received between the back side vicinity of the lower end of the backpack 8 and the back, the backpack auxiliary tool 1 may be attached by other methods.

With the use of the assisting device 1 for the backpack, it is more difficult for the shoulder strap 5 of the shoulder strap 5 of the backpack 8 to have a wider width between the shoulder straps (see 12-1 in FIG. 12). It is effective in reducing the weight burden.

As shown in FIG. 13, the backpack 8 in which the auxiliary tool 1 of the backpack is mounted in the vicinity of the back side of the lower end portion of the backpack 8 from the beginning is also effective. The auxiliary tool 1 of the backpack is mounted on the inner side of the lower end portion of the surface applied to the back of the backpack 8 so that the surface along the back faces outside, and the surface applied to the back of the backpack 8 is covered and sewn. There is a sense of stability when the assisting device 1 of the backpack hits the back, and the weight of the backpack 8 can be firmly applied to the back. Moreover, there is no trouble of attaching with the fixture 2, and it does not dangle. If you have a structure that allows you to adjust the size by taking in and out the air, you can make it the size that suits you.

You may attach the belt 9 to the auxiliary tool 1 of a backpack, or you may attach the auxiliary tool 1 of a backpack to the belt 9, such as trousers. In this case, the same effect can be obtained by arranging the auxiliary tool 1 for the backpack on the back side (FIG. 14) and sandwiching it between the back side of the lower end of the backpack 8. At that time, if a projection 11 that can securely place the backpack 8 is attached to the lower end portion of the auxiliary equipment 1 of the backpack (FIG. 17), the weight of the backpack 8 is more reliably received and the weight is also applied to the back and waist. Can be distributed.

In addition to making the shape of the assisting device 1 of the backpack substantially rectangular parallelepiped, it has a surface along the back and a surface along the backpack 8 so that the weight of the backpack 8 can be received and is lightweight. Other shapes are possible, such as constriction between the faces (FIG. 16). As a result, design can also be developed.

It is possible to attach not only one but also a plurality of auxiliary tools 1 for the backpack and find an easy backpack that suits you. For example, the auxiliary tool 1 of the backpack is attached to both sides of the lower end portion of the shoulder strap 5 of the backpack 8 with the mounting tool 2, but the two auxiliary tools 1 of the backpack are put on top of each other or vertically between them. You can also put them side by side.
Further, the size of the auxiliary tool 1 for the backpack may be changed according to the size of the backpack 8.

By sandwiching the assisting tool 1 of the backpack between the back side of the lower end of the backpack 8 and the back, a space is vacated in the back portion above the assisting tool 1 of the sandwiched backpack. Therefore, adhesion between the backpack 8 and the back can be prevented, and stuffiness can be prevented. When the backpack is carried on the back, the close contact part of the back such as midsummer becomes sweaty, but if the back support tool 1 is used, it can be carried comfortably.

It is also effective to provide unevenness with a moderate elasticity on the surface of the assisting tool 1 on the back that contacts the back. If it is shaped to fit the points on the back, it can be pressed with a walking rhythm and expect a massage effect. A similar effect can be obtained by placing a cover along the back and a surface along the back with a slightly soft cloth on the cover of the auxiliary device 1 of the backpack, attaching a chuck, and putting a few balls with air inside. can get.

If the backpack 8 has a length up to the hips when the backpack 8 is carried on the back, there will be a surface along the back of the back support tool 1 so that the back of the backpack should be The surface along the back of the assisting tool 1 can be put on the surface, and it is comfortable and stable. The weight of the backpack 8 can be easily received.

Considering colors and shapes, it can be used for backpacks for work, backpacks for work, school bags, backpacks for attending school, or fashionable town backpacks for women. It can be shaped according to the needs of the user, such as thin or large, and can be color-matched to clothes and backpacks, and design can be added.

Since it is simple and light, it can be used comfortably without feeling weight.

Since the auxiliary tool 1 of the backpack is sandwiched between the backpack 8 and the back, the impact of the backpack 8 hitting the back when running or jumping off can be reduced. It can also be useful during emergency evacuation such as disasters.

Children and students who go to school carry heavy backpacks 8 on their daily trips. By dispersing the weight of the backpack 8 not only on the shoulder but also on the back, it is possible to reduce the stiff shoulder that causes the body to malfunction.

The auxiliary tool 1 for the backpack is removable and is light and almost rectangular parallelepiped, so it can be used instead of a small pillow when removed. It can be used not only for lying down in a tent during outdoor activities, but also for a short nap when lying down at a desk during work or school breaks.

Backpacks for commuting to school, fashionable backpacks in town, school bags, backpacks used in farming, mountain climbing, and other types of backpacks can be used.
Recently, rucksacks have become popular, and I often see young and old men and women carrying them. If you use a backpack, your hands are free, so you can use it for other tasks such as holding other luggage or paying money out of your wallet.
However, I often hear that elderly people and people who carry heavy luggage carry their shoulders for a long time. If the pain of the backpack can be reduced, the backpack can be used comfortably.
In the future super-aging society, nursing care for the elderly will also increase, and it will be necessary to do things for yourself, so it is expected that carrying backpacks will increase in the future. Recently, disasters and earthquakes are frequent. In the event of an emergency evacuation, you may carry as much of your possessions and necessary items as possible. In such a case, the assisting device of the backpack of the present invention can reduce the fatigue of the body because the burden on the shoulder can be dispersed with the back, and the impact of the backpack on the back is reduced when running and jumping, It can also be very useful as it helps prevent stuffiness of the back when it is hot.
It is a gentle invention that takes into account the burden on the body.
