Description

Technical Field

[0001] The present invention belongs to the field of assisting the disabled, and particularly relates to a lumbar torsion walking vehicle. Background Art

[0002] Due to the influence of factors such as the body weight, aging, other external gravity, pressure, occupational habitual postures, natural disasters, and man-made disasters over a long period of time, various defects or disabilities may occur in people's bodies. These diseases bring pain and discomfort to patients in the cervical spine, lumbar spine, upper limbs, lower limbs, etc. For those who have physiological problems with their legs and cannot walk, walking aids undoubtedly become essential products for their lives. Currently, common walking aids are wheelchairs, armrests, and crutches. However, these walking aids require strong and healthy arms to be used. If this group of people also have diseases in their arms and cannot drive the existing walking aids, the currently common walking aids cannot be used normally. In view of this, the present invention develops a lumbar torsion walking vehicle. This walking vehicle does not require external power such as electricity, and only by twisting the lumbar spine can the elderly or people with diseases in their limbs walk instead, so as to assist in tasks such as fetching and delivering objects. During the process of walking instead, the lumbar spine and other parts can also perform appropriate exercises, playing roles such as rehabilitation and fitness. Summary of the Invention

[0018] Such as Figure 1 — Figure 7 , when the lumbar-twisting walking vehicle needs to move forward, first, the elderly or people with limb diseases sit on the seat 2 of the walking vehicle, hold the faucet 1 of the walking vehicle with both hands, and drive the lumbar-twisting walking vehicle forward through the left-right twisting of the lumbar spine, transmitted by the chain drive mechanism and the double-spined bevel gear one-way mechanism. The double-spined bevel gear one-way mechanism effectively ensures that the walking vehicle can be driven forward whether the lumbar spine twists to the left (clockwise) or to the right (counterclockwise), greatly improving the efficiency.

[0019] When the lumbar spine twists to the left (clockwise), the power is transmitted through the driving sprocket 12, the chain 11 and the driven sprocket 10 to make the double meshing bevel gear 18 also twist to the left (clockwise). Because both sides of the double meshing bevel gear 18 are simultaneously meshed with the right ratchet bevel gear 15 and the left ratchet bevel gear 16, at this time, the right ratchet bevel gear 15 rotates clockwise, and the left ratchet bevel gear 16 rotates counterclockwise. Also because the right ratchet 20 ensures that the right ratchet bevel gear 15 rotates synchronously with the double ratchet shaft 17 clockwise, and the right ratchet bevel gear 15 idles on the double ratchet shaft 17 when rotating counterclockwise, and the left ratchet 19 ensures that the left ratchet bevel gear 16 rotates synchronously with the double ratchet shaft 17 clockwise, and the left ratchet bevel gear 16 idles on the double ratchet shaft 17 when rotating counterclockwise. Therefore, at this time, the right ratchet bevel gear 15 rotates synchronously with the double ratchet shaft 17 clockwise, and the left ratchet bevel gear 16 idles on the double ratchet shaft 17. The double ratchet shaft 17 is driven by the right ratchet bevel gear 15 to rotate clockwise, and the double ratchet shaft 17 drives the right wheel 6 and the left wheel 8 to rotate clockwise, and the lumbar-twisting walking vehicle moves forward.

[0020] When the lumbar spine twists to the right (counterclockwise), power is transmitted through the driving sprocket wheel 12, the chain 11, and the driven sprocket wheel 10 to cause the double-engaging bevel gear 18 to also twist to the right (counterclockwise). Since both sides of the double-engaging bevel gear 18 are simultaneously engaged with the right ratchet bevel gear 15 and the left ratchet bevel gear 16, at this time, the right ratchet bevel gear 15 rotates counterclockwise and the left ratchet bevel gear 16 rotates clockwise. Also, because the right ratchet 20 ensures that the right ratchet bevel gear 15 rotates synchronously with the double-ratchet shaft 17 clockwise, the right ratchet bevel gear 15 idles on the double-ratchet shaft 17 during counterclockwise rotation. The left ratchet 19 ensures that the left ratchet bevel gear 16 rotates synchronously with the double-ratchet shaft 17 clockwise, and the left ratchet bevel gear 16 idles on the double-ratchet shaft 17 during counterclockwise rotation. Therefore, at this time, the right ratchet bevel gear 15 idles on the double-ratchet shaft 17, the left ratchet bevel gear 16 rotates synchronously with the double-ratchet shaft 17 clockwise, the double-ratchet shaft 17 is driven by the left ratchet bevel gear 16 to rotate clockwise, and the double-ratchet shaft 17 drives the right wheel 6 and the left wheel 8 to rotate clockwise, and the lumbar spine twisting walking aid moves forward.

[0021] In summary, whether the lumbar spine twists to the left (clockwise) or to the right (counterclockwise), it can drive the double-ratchet shaft 17 to rotate clockwise. The double-ratchet shaft 17 can drive the right wheel 6 and the left wheel 8 to rotate clockwise, and can make the walking aid move forward.

[0022] During the process of the lumbar spine twisting walking aid moving forward, the direction of the walking aid moving forward is controlled by holding the handlebar 1 of the walking aid with both hands.
