- a so-called " ⁇ -shaped cane” having a substantially right-angled handle at the upper end of a single rod-shaped body is commonly used to assist walking. It moves with changing the tilt (hereinafter referred to as “tilting”) and supports the weight in good rhythm.
- tilt hereinafter referred to as “tilting”.
- ( ⁇ ) is a state in which the wand is swung in the forward direction, that is, in the direction of travel at the start of walking, in order to deposit weight
- (F) is a state where the walking stick that has deposited the weight is approximately upright
- (G) shows a state in which the walking stick is inclined forward as the pedestrian moves forward by one step.
- the cane can be operated only by the operation of the wrist joint without changing the angles of the upper arm and the forearm suitable for operating the cane. In other words, it assists natural and smooth walking with little arm movement.
- the palm since the load applied to the handle acts to defeat the stick, the palm must be turned to apply rotational force to the handle in order to keep the cane standing.
- the rotational force to be applied in the counterclockwise and clockwise directions indicated by arrows, respectively is maximum.
- the state (F) is a so-called tilting dead point where the cane can fall in either direction, and in this state, it is difficult to control the fall of the cane at the wrist joint, and the cane does not wobble. It is stable, but can pass smoothly in a continuous walking process.
- a cane known as the "mouth-mouth strand clutch" known by President Clinton was used.
- This is provided with a forearm holder called a cuff which is formed in a cylindrical shape so that the forearm can be passed through the upper end formed by extending the cane column further upward, so that the rotation of the cane cannot be suppressed by the entire forearm. It controls stable wander and keeps weight. Therefore, the wrist can be controlled so that the wobble can be suppressed both at rest and during operation, reducing the burden on the wrist. It is suitable as a walking stick for a patient suffering from a disability, such as a leg having a disability, to step by step.
- the present invention provides a connecting means for connecting the forearm holder arranged above the grip handle so as to be tiltable rearward with respect to the walking stick when pressed by the pedestrian's forearm, and when the pressing is released. It is configured to have a biasing means for biasing it to return to the original position, and the “ ⁇ -shaped cane” and the “mouth It seeks to solve the problem of combining the advantages of both hands and compensating for the disadvantages. In the walking process shown in (E), (F), and (G) of FIG. 2, the walking stick tilts forward.
- the forearm of the pedestrian trying to maintain an appropriate angle to poke the cane pushes the forearm holder, which tries to tilt forward with the cane column, backward and tilts backward with respect to the cane column.
- the forearm that holds a moderate biasing force Holds the forearm, which receives a large amount of rotation in the direction of the arrow with a small force in combination with the palm that holds the handle, so that the pedestrian keeps the angle of the forearm suitable for sticking the stick.
- the weight can be stored on the walking stick without imposing a burden on the wrist or elbow joint.
- the elbow joint can be used to operate the stick while holding the handle at the natural angle of the forearm that has been appropriately bent without forcing unnatural bending and extension, and the entire forearm becomes the forearm holder.
- it is hard to fall down while receiving an appropriate biasing force and is supported stably, so that walking can be done naturally and smoothly without wobbling of the walking stick. It solves the problem of reducing the burden on the wrists and arms and assisting continuous walking up to a natural posture without vertical movement.
- a cane according to the present invention comprises a cane column formed by extending in the shape of an upright bar, a grip handle provided above the cane pillar, and a pipe-shaped or opening formed above the grip handle and having a front end. That is, a forearm holder formed to extend in the upright direction in the shape of a half pipe directed in the advancing direction, and when the forearm holder is pressed rearward, the forearm holds the cane pillar in the advancing plane including the axis thereof. It is provided with a connecting means for movably connecting and urging means for urging to return to the original position when the pressing is released.
- the forearm holding tool is pressed by the forearm and tilts rearward with respect to the cane pillar that tilts forward, that is, in the traveling direction in the walking process, so that the pedestrian can push the cane.
- An appropriate angle of the forearm can be maintained, and the forearm holding member can receive the appropriate biasing force, thereby suppressing the wobble of the cane and keeping the weight stably.
