BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a rucksack or backpack used for mountain climbing, hiking, skiing, and the like.

[0002]

2. Description of the Related Art Generally, conventional rucksacks or backpacks have left and right backing belts fixed to both upper and lower ends, and can only be adjusted in length. Therefore, the user had to adjust the length of the carrying belt according to his / her physique and height.

[0003]

However, as described above, in the conventional rucksack, since the two backing belts are fixed separately on the upper and lower sides of the rucksack main body, climbing, running, etc. with the rucksack on the back are carried out. When performing exercises such as skiing, cycling, climbing up and down stairs, etc., there is a drawback that the left and right shoulders move up and down in conjunction with the waist up and down movement, and the rucksack tilts to the left and right and rolls did. This has the disadvantage that the weight balance of the rucksack always shifts left and right for the user, and the shoulders or legs become very tired.

[0004] Also, since the two backing belts are fixed separately on the upper and lower parts of the rucksack body, most of the load of the rucksack will be hung on the shoulder to be raised,
The heavier the backpack, the more limited the movement of the shoulders due to the fixed backing belt. Furthermore,
The shoulder opposite to the one you are trying to raise makes a downward movement due to the reaction, and the constant-length backpack slacks,
There was the drawback of trying to get off the shoulder. The disadvantages above are
The same applies to a backpack.

SUMMARY OF THE INVENTION In view of the above problems of the conventional rucksack, the object of the present invention is that even when the left and right shoulders are alternately raised and lowered, the rucksack main body does not largely tilt, but fits firmly to the body and has good balance. To provide rucksacks. Another object of the present invention is to provide a rucksack that enables light movement of the body during exercise while carrying the rucksack and that does not cause the belt on the lower side to come off.

[0006]

In order to achieve the above object, a rucksack of the present invention comprises a rucksack main body, and left and right shoulder belts fixed to an upper portion on the back side of the rucksack main body. The lower ends of the left and right shoulder belts are connected to each other at a supporting portion to form a loop, and the supporting portion is slidably inserted into a communication hole formed along a lower end of the rucksack body. Things. Further, a sliding plate made of a synthetic resin is provided in a part of the communication hole.

[0007] The backpack belt is characterized in that the amount of sliding is regulated by fixing belts arranged on both sides of the lower end of the backpack main body. Also,
The branch connected to the back belt is made of slippery fiber.

[0008]

In the rucksack according to the present invention, the lower end portion of the backpack belt is continuous and moves left and right as the left and right shoulders and waist are moved up and down and right and left, so that the rucksack body is almost inclined. But still fits the body.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 is an overall perspective view showing an embodiment of the rucksack of the present invention, FIG. 2 is a longitudinal sectional view of the rucksack of the present invention, and FIG. 3 is a partially cutaway perspective view showing a communication hole of a backpack belt of the rucksack. FIG. 4 is a longitudinal sectional view of the through portion.

[0010] Here, reference numeral 10 denotes a rucksack main body, and shoulder belts 11, 11 are fixed to upper left and right ends. The backpack belt 11 is composed of a main trunk 11a serving as a wide shoulder pad and a belt 11b connected thereto. The belt 11b is formed of a single belt-like belt.
It is connected to 1a to form a loop.

The main trunk portion 11a has a built-in sponge and the like so that the shoulder does not hurt when carrying. And the branch 1 for the main manager 11a.
The connection of 1b is made by connecting members 12, 12 whose lengths can be adjusted at both ends of the belt-shaped belt. The connecting tool 12 is made of plastic (engineering plastic) or the like, but may be made of metal.

The branch 11b is made of synthetic fiber which is slidable in the longitudinal direction. In addition, the branch portion 11b is provided so as to penetrate through a communication hole 13 formed at the lower end of the rucksack body 10. The communication hole 13 has openings 13a, 13a on the lower left and right sides of the backpack main body 10,
The branch portion 11b inserted inside can freely slide.

As shown in FIGS. 3 and 4, a flexible sliding plate 14 made of synthetic resin is provided inside the communication hole 13. As shown in FIG. The sliding plate 14 is inserted and supported by bag-like portions 19, 19 formed of separate members so that both ends do not come off.
The slide plate 14 is made of, for example, styrene resin or the like, and is made of a resin having a smooth surface. The sliding plate 14 is
It also contributes to maintaining the shape of the lower end of the rucksack body 10.

The fixing belts 15 are fixed to both sides of the lower end of the rucksack body 10, respectively.
b, the connecting parts 16 provided on the b.
b. By connecting the fixing belt 15 to the supporting portion 11b with an appropriate length, the supporting
1b can be restricted in the lateral movement amount.

At the lower end of the rucksack body 10, a waist belt 17 is fixed to the left and right.
It can be tightened at a and 18b. This waist belt 17
Thereby, the rucksack main body 10 can be tied around the waist of the user. Thereby, the lower end of the rucksack main body 10 is restrained, and the sliding of the supporting band 11b can be easily performed.

The rucksack main body 10 is made of a fiber such as a synthetic resin, is waterproofed, and is configured so that rainwater or the like does not permeate. In addition, a backrest 10a having a sponge or the like is formed on the back of the backpack main body 10, so that the back does not hurt when the user carries the backpack.

A handle 21 is attached to the top of the rucksack main body 10, which is convenient for slightly moving the rucksack main body 10 when the rucksack main body 10 is lowered from the shoulder. In addition, a plurality of loop-shaped portions 22 are formed on the front surface of the rucksack body 10, and small items such as a cup and a folding umbrella can be attached via a strap or the like.

Next, a method of using the thus constructed rucksack will be described. First, an appropriate luggage is put in the rucksack body 10 and is carried on the back of the user. At this time, the chief executive 1 according to the physique and height of the user
The length of 1a and the band 11b is adjusted and fixed with the connector 12. Next, after tightening the waist belt 17 and adjusting the length,
It is fixed with the fixture 18.

When the right hand is raised in such a rucksack of the present invention as shown in FIG. 5, for example, the right shoulder rises and the right main body 11a is raised. When the main trunk 11a is raised, the branch 11b connected thereto is also raised in the direction of arrow A. Arrow A at the right end of the branch 11b
When it moves in the direction, the loop-shaped portion located in the communication hole 13 of the branch moves in the direction of arrow B near the upper part of the waist.

When the loop-shaped portion of the supporting portion 11b located in the communication hole 13 moves in the direction of arrow B, it descends in the direction of arrow C at the left end. Therefore, the trunk portion 11a of the left shoulder which has been lowered has no tarm, and the rucksack body 10
Is always fit to the user's body. For this reason, the rucksack main body 10 does not largely tilt or move left and right, and fatigue is reduced even when used for a long time.

Further, since the amount of movement of the supporting portion 11b is regulated within a predetermined range by the fixing belt 15, it does not move indefinitely, and the balance may be lost even if the body is extremely inclined. Absent.

Also, as shown in FIG.
If the belt 20 tying a is attached,
Can be prevented from coming off the shoulder. In other words, if the belt 20 is tied after carrying the shoulder, there is no danger that the carrying belt 11 will come off the shoulder even if the left and right shoulders are violently moved.

Although the above embodiment has been described in connection with a rucksack, the present invention can be similarly applied to a backpack. In other words, the left and right shoulder belts are fixed to the frame body to which luggage and the like are attached, and the left and right shoulder belts are fixed to the upper part on the back side of the frame body, and the lower ends of the left and right shoulder belts are continuous with the strap part to form a loop, The portion is slidably inserted into a communication hole formed along a lower end of the frame main body. Further, without being limited to these embodiments, various modifications can be made based on the technical idea of the present invention.

[0024]

As described above, the rucksack of the present invention comprises a rucksack body and left and right shoulder belts fixed to the upper portion on the back side of the rucksack body, and the lower ends of the left and right shoulder belts. Since the portion is continuous with the supporting portion to form a loop and the supporting portion is slidably inserted into a communication hole formed along the lower end of the rucksack body, one shoulder is raised, and the other is raised. When the shoulder is lowered, the lower branch can be moved upward through the communication hole, and the rucksack body does not tilt significantly. Therefore, during exercise such as mountain climbing, running, and going up and down stairs, light movement of the shoulders has become possible.

Further, the disadvantage that the left and right shoulders are moved up and down and the rucksack is tilted to the left and right to cause a sideways movement has been eliminated, so that the weight balance of the rucksack is always kept constant, and the shoulder or leg is kept constant. It can reduce fatigue of the waist.

Furthermore, since the load of the rucksack body does not significantly apply to the shoulder to be raised, the amount of movement of the shoulder is not limited by the shoulder belt. In addition, even if the shoulder opposite to the shoulder to be raised goes down due to the reaction, the shoulder bag slacks and does not come off from the shoulder. For this reason, the user is less tired even after using for a long time.

Further, since a sliding plate made of synthetic resin is provided in a part of the communication hole, the branch can be moved right and left without difficulty, and quickly follows changes in the entire body such as the left and right shoulders and waist. Can do things. Further, since the amount of sliding of the backpack belt is regulated by the fixing belts provided on both sides of the lower end of the rucksack main body, the supporting band does not move indefinitely and does not lose its balance. The branch connected to the shoulder belt is made of slippery fiber, so that it can move to the left and right smoothly, without any excessive force, and can move easily. The same effect can be obtained when applied to a backpack.
