Description

Technical Field

[0001] The present invention relates to a cylinder - type walking assist device that uses a cylinder made of an aluminum drawn tube to constantly lift the human body and reduce the burden on the feet, waist, and knees because the burden on the feet, waist, and knees during walking is large, causing fatigue and pain.

Background Art

[0002] During walking, the feet, waist, and knees are constantly burdened, resulting in fatigue and pain, making the movement strenuous.

Problems to be Solved by the Invention

[0004] During walking, since the feet, waist, and knees are constantly burdened, fatigue and pain occur.

Means for Solving the Problems

[0005] During walking, the cylinders 1a, 1b made of an aluminum drawn tube with pneumatic pressure enclosed and attached to the human body lift the human body, reducing the burden on the feet, waist, and knees and alleviating fatigue and pain. To facilitate movement, the upper part of the outer cylinder of the cylinder is attached to the human body using a fixture and a holder, and the lower part of the inner cylinder of the cylinder is attached to a walking shoe holder.

Effects of the Invention

[0006] During walking, the burden on the human body is borne by the pneumatic pressure - enclosed cylinders 1a, 1b, reducing the burden on the feet, waist, and knees. The pneumatic pressure - enclosed cylinders 1a, 1b have their upper parts attached to the human body using a fixture 2, a band holder 3, and a loop - hanging holder 4. The lower parts of the cylinders are fixed to the walking shoe holders 5a, 5b. Hereinafter, embodiments of the present invention will be described. (a) When walking, the pneumatic cylinders 1a and 1b are attached to the human body by the fixture 2 and the holders 3, 4, and 5, and the pneumatic pressure of the cylinders acts in the direction of always lifting the human body during walking.

Example 1

[0007] Figure 1 shows the state of wearing the cylinder - type walking assist device on the human body. Figure 2 shows the state during walking while wearing the cylinder - type walking assist device. Figure 3 shows the state when going up stairs, and Figure 4 shows the state when going down stairs. Figure 5 shows the cross - sectional shape of the cylinder, and Figure 6 shows the details of parts A - C of the cylinder cross - section.

[0008] In Figure 1, the side and back views of the cylinder - type walking assist device are shown in the state of being worn on the human body. The upper parts of the pneumatic cylinders 1a and 1b are attached to the human body by the fixture 2, the band holder 3, and the loop - hanging holder 4. The lower parts of the cylinders are fixed to the walking - shoe holders 5a and 5b and receive the human - body lifting force by the enclosed pneumatic pressure in the cylinders. The cylinder stroke is adjusted according to the height of the person by the cylinder - stroke adjustment wires 6a and 6b. The fine adjustment of the stroke is adjusted by the bolts of the wire - adjustment bolt fixtures 8a and 8b. Adjusters 15 are attached to the upper and lower parts of the cylinder so that the movement of the human body can be made easily. Cylinder - stroke lower - limit set collars 7a and 7b are attached as the stroke ends when squatting and stopping during running.

[0009] In Figure 2, the state during walking is shown. The attachment state of the cylinder - type walking assist devices 1a and 1b is shown. The movement during walking can be done easily.

[0010] Figure 3 shows the attachment state of the cylinder - type walking assist devices 1a and 1b when going up stairs, and Figure 4 shows the attachment state when going down stairs.

[0011] In Fig. 5, the cylinder cross-sectional shapes of the pneumatic cylinders 1a and 1b of the cylinder-type walking assist device are shown. The outer cylinder 10 and the inner cylinder 11 are made of aluminum drawn tubes. For preventing the outer cylinder and the inner cylinder from being pulled out, the lower seal fitting 12 and the upper seal fitting 13 are connected by a retaining wire 16. The pneumatic pressure is sealed from the pneumatic supply fitting 17 with a check valve. A guide fitting 14 is attached to the lower part of the outer cylinder 10 and guides and slides on the inner cylinder 11. An adjuster 15 that can freely tilt is attached to the attachment part of the upper seal fitting 13 of the outer cylinder 10 to the fixture 2. An adjuster 15 is attached to the attachment part of the lower seal fitting 12 of the inner cylinder 11 to the walking shoe holders 5a and 5b. The nature of the pneumatic pressure PV κ =constant is utilized to enclose water inside the cylinder to control the volume of the air chamber, enabling control of the force by the cylinder stroke.

[0012] In Fig. 6, the cross-sectional shape details of the A, B, and C parts of the cylinder cross-sectional shape in Fig. 5 are shown. In the details of part A, the seal details between the piston 18 and the outer cylinder 10 are shown. The piston 18 is fixed to the inner cylinder 11 with a retaining pin 20. The attachment details of the guide fitting 14 to the outer cylinder 10 and the penetrating state of the retaining wire 16 through the piston 18 are shown. In the details of part B, the upper seal fitting 13 is attached to the outer cylinder 10 with a retaining pin 19, and the seal details are shown. The attachment of the adjuster 15, the attachment of the pneumatic supply fitting 17 with a check valve, and the attachment state of the retaining wire 16 are shown. In the details of part C, the lower seal fitting 12 is attached to the inner cylinder 11 with a retaining pin 21, and the seal details are shown. The attachment of the adjuster 15 and the attachment state of the retaining wire 16 are shown.
