The present invention relates to a leg assisting device for legless work, and more particularly, to support a calf and hips while sitting or working in a rural area such as paddy or field work or welding, without straining the leg. It relates to a seating assistive device to ease the waist.

In general, when working in fields such as field work or rice fields or welding in rural areas, because the working person has to squat and work for a long time, the work is very difficult and the legs or knees and legs are very painful.

In other words, when squatting and working, the weight is concentrated on the legs and the concentration on the knees causes problems such as poor circulation of the blood, which causes the legs to fall easily or the knee hurts.

Therefore, the applicant has filed a "leg support device for seating work" as a Korean Patent Application No. 2005-95703 dated October 11, 2005, which is located between the calf A and the thigh B as shown in FIG. A close contact plate 50 and a main body 51 supporting the thigh and the calf, respectively, a spring 52 provided between the close contact plate 50 and the main body 51 and configured to apply elasticity; It consists of a coupling band 53 provided to fix the 51 to the calf.

That is, when the work is bent in the leg in the state placed between the body 51 and the contact plate 50 between the calf (A) and the thigh (B), the thigh is supported by the elasticity of the spring 52, You will be able to work in a more comfortable sitting position.

However, as described above, when supporting the sitting position formed by the elastic body between the thigh and the calf and the contact plate, the entire weight is supported only by the calf, so that the calf is overloaded too much. There is a problem that fatigue progresses quickly.

In addition, since the weight is concentrated between the thigh and the calf as described above, there is a problem that it becomes very difficult to hold the center in the sitting position.

Accordingly, an object of the present invention is to solve the above problems, the weight of the legs and knees are distributed to the legs and the ground when the worker sitting and working squat reduces the fatigue of the legs and sitting in the sitting position It is to provide a leg support device for sitting work that can be easily centered, improving work efficiency.

In order to achieve the above object, the present invention, the lower base is formed so that the shoe and the ankle portion is received and the band coupling portion formed with a coupling hole formed to engage / separate the fixing band provided with the magic tape, and the above-mentioned, A first plate rotatably coupled to the upper surface of the lower base and supporting the inner surface of the calf; Elastic installed between the plate and the lower base and the second plate to elastically support the second plate when pressed by a human load, and to distribute and absorb the load to the lower base to the ground. It is characterized by the configuration by means.

1, 2 and 3 are exploded perspective view and assembly side view and bottom perspective view of the leg assisting device for the seating work according to the present invention, the shoe (C) and the ankle portion is formed so as to receive the magic tape (1) Rotatable on the upper base of the lower base (5) and the upper base of the lower base (5) protruding the band coupling portion (4) formed with a coupling hole (3) to engage / separate the installed fixing band (2) It is coupled to the link member 6 and the hinge (7) and the first plate (8) formed in a gentle curved surface to support the inner surface of the calf, and the first plate (8) and one side of the hinge shaft (9) The second plate 11 formed to support the bottom of the thigh B and the buttocks, and the elastic pad 10 is installed, and the lower base 5 and the second plate 11. Elasticity when the second plate 11 is pressed by a human load In addition to this, and also the support by passing the load to the lower base (5) consists of a resilient means is provided so as to disperse and absorb the ground.

As shown in Figs. 2 and 4a, the elastic means includes an arm 12 protruding from the rear surface of the lower base 5 and disposed up and down, and a piston member fixed to the arm 12. 13), the cylinder member 14 is formed so that the piston member 13 is inserted and the upper end is supported on the other side of the second plate 11, and the piston is inserted into the cylinder member 14 It consists of a spring 15 which generates elasticity with the member 13.

That is, when the second plate 11 is pressed by the weight, the spring 15 is compressed to cushion the impact and the load, and the load is lowered through the piston member 13 and the arm 12 through the lower base 5. By transmitting to), the load is distributed and absorbed to the ground through the lower base (5) in close contact with the ground.

When the user's weight is dispersed and absorbed through the lower base 5 to the ground, the load applied to the first and second plates 8 and 11 that substantially supports the user's legs is reduced, so that the user's calf or the like becomes excessive. It is to prevent the applied load to be able to sit and work more comfortably.

Here, the bottom portion 16 is formed on the bottom surface of the lower base 5 so that the user can step on the foot after wearing the bar. By being fixed by the foot, it is possible to support the user more stably.

In particular, the height adjusting means is provided between the piston member 13 and the lower base 5 so that the height adjustment is possible, which is a plurality of insertion holes 17 formed at regular intervals in the piston member 5 and , The fixing hole 18 formed in the arm 4 so as to correspond to the insertion hole 17, and the fixing rod 19 inserted into the fixing hole 18 and the insertion hole 17 to fix it. have.

The fixing rod 19 is formed in a "⊂" shape is inserted into the two fixing holes 19 at the same time to further improve the fixing force.

In addition, the end of the piston member 13 and the cylinder member 14, the engaging projection 20 is formed so as to engage with each other, in the state in which the engaging projection 20 is caught in the elasticity of the spring (15). As a result, the piston member 13 and the cylinder member 14 are not easily separated.

Here, the folding means is provided between the second plate 11 and the cylinder member 14 so as to fold the second plate 11 as shown in Figs. 4a and 4b. The means is to allow the second plate 11 to be folded and free to move when the wearer sits up while working.

The folding means includes an insertion portion 21 formed at an upper end of the cylinder member 14 and a locking groove 22 formed at a bottom surface of the second plate 11 so that the insertion portion 21 is inserted and coupled relatively shallowly. ) And a guide portion 23 formed on the bottom surface of the second plate 11 so as to move while supporting the cylinder member 14 detached from the locking groove 22.

That is, when the second plate 11 rotates in the counterclockwise direction about the hinge axis 9, the cylinder member 14 moves on the guide part 23, thereby being folded as shown in FIG. 4B. will be.

Of course, the second plate 11 and the cylinder member 14 may be folded even when only the engaging groove 22 is coupled, but there is a risk of escaping to the left and right sides of the second plate 11.

Here, when the coupling of the second plate 11 and the cylinder member 14 is coupled to the hinge H as shown in FIG. 6, the second plate 11 is not folded at a large angle as shown in FIG. Will be folded to some extent, and since the second plate 11 is fixed, it is possible to sit more stably.

When explaining the operation and effect of the present invention as described above, in order to work for a worker who works such as paddy field, field work, welding, or the like, the cylinder member 14 opens the second plate 11 and the second plate first. (11) is adjusted to be caught in the locking groove (22).

In this state, the lower base 5 is placed on the heel of the foot, the foot 16 of the lower base 5 is stepped on with the foot, and then the fixing band 2 is wound around the ankle and installed at both ends of the fixing band 2. The magic tape 1 is attached to fix the foot.

When the lower base 5 is fixed to the ankle by the fixing band 2, the operator sits on the second plate 11 as shown in FIG. 2. In this state, the second plate 11 is the thigh B. ) And the first plate (8) is located on the back of the calf (A).

As described above, when the first and second plates 8 and 11 are located between the calf A and the thigh B, the first and second plates 8 and 11 are formed to support the legs in a sitting position, and the bottom of the second plate 11 Since the installed cylinder member 14 is elastically supported by the spring 15, the worker can sit and work comfortably.

That is, the load of the operator is transmitted to the cylinder member 14 while being applied to the second plate 11, and is buffered by the spring 15, and again the lower base 5 through the piston member 13 and the arm 12. The lower base 5, which is in contact with the ground, supports the load of the worker.

Since the load applied to the worker's leg is substantially reduced when the worker's load is transmitted and absorbed to the ground, even if the worker is sitting and working, the legs can be greatly reduced from falling or hurting.

Here, in the case where the operator's sitting height is large or small, the insertion hole 17 formed in the piston member 13 after the fixing rod 19 is removed to adjust the height of the second plate 11. When inserted by moving up or down in the) is the height adjustment of the second plate 11 is made to be appropriately adjusted according to the body to the operator can be used.

If you stand up to move after sitting and working as described above, the first plate 8 is pushed to the left to rotate the second plate 11 in the counterclockwise direction, so that it is in close contact with the legs and easy to move. .

That is, as shown in FIGS. 4B and 5, when the first plate 8 is pushed to the left side, the cylinder plate 14 is separated from the bottom engaging groove 22 of the second plate 11 and the second plate ( 11) is rotated counterclockwise about the hinge axis (9), it is in a folded state as shown in FIG.

At this time, since the cylinder member 14 and the piston member 13 are caught by the locking protrusion 20, they are not separated even by the elasticity of the spring 15.

As described above, according to the present invention, when the users who sit and work for a long time sit on the calf, the thighs are elastically supported so that the loads are not concentrated on the legs and knees, and the loads are dispersed and absorbed by the ground. There is an advantage that becomes very easy.
