Description

The present invention relates to a cane for a disabled person or an elderly person with one hand paralyzed.

Although there are excellent canes in the conventional self-standing canes, there are many canes that are too complicated, and there are many cases that have problems such as failure, durability, and high cost. In addition, there is anxiety about use when it rains or snows, and there is a lack of research regarding the resetting by closing the tripod. For example, the cane disclosed in Japanese Patent Application Laid-Open No. 2005-130966 can be reset by pulling the string, or Because both hands, such as a cane that closes like an umbrella, are used, disabled people and elderly people who are paralyzed with one hand, elderly people who have luggage and can use only one hand will be in trouble.

  By making the structure simpler than the conventional self-supporting cane, aiming for a cane that is less expensive, less costly, light, durable, and highly practical, the biggest challenge is the disabled and elderly with paralysis of one hand, For elderly people with luggage, the purpose is to provide a self-supporting cane that can be quickly reset by a simple operation with only one hand, closing the leg and quickly resetting it to a cane shape.

A vertically moving body with a handshake fits on the outside of the main column, and a push-up ridge is placed between them. When the handshake fixed to the vertically-moving body is pressed, the push-up ridge shrinks, and the vertically moving body also lowers and shrinks, releasing the handshake. The action of the push-up ridge causes the vertically moving body to be pushed up and return to its original position.This movement is used, and when the handcuff is pushed down, the cane up and down moves up and the cane up and down is pushed up. When combined with a leg that has a reversing function, it reverses when it moves upward and reverses the transmitted movement. Provided with a plurality of reversing legs having a reversing function at the lower end of the cane, with the long tip from the fulcrum shaft as the ground end and the short tip as the reversing end, the bottom end of the vertical moving body, and the reversing end of the reverse reversing leg In between, the transmission shaft is connected, and the vertical movement of the vertical moving body is transmitted to the reverse leg. When closing the open leg, when the handshake is pushed, the vertically moving body also lowers, the push-up ridge also shrinks, and when the transmission shaft and the inverted end of the reverse-shaped inverted leg are also lowered, the opposite grounding end On the other hand, when it closes up, the clasp is automatically held down, the leg can be reset, and it returns to a cane shape. Also, when the above-mentioned restraining clasp is removed, the vertically moving body is pushed up by the action of the push-up ridge, and when the transmission shaft and the reversing end are pulled up, the grounding end opens downward and becomes self-supporting.

  A handicapped person with one hand paralyzed or an elderly person suddenly needs to use his hand, and when releasing the cane, simply press the button with his thumb to instantly open the flipped leg and support the cane from falling down. The cane stands upright and stands independently. The cane stands up at the touch of a button at any time, anywhere, indoors or out, except on slopes. The reset, which can be easily returned to a cane even by a disabled person with one hand paralyzed, simply pushes the handshake downward, both the vertical moving body and the middle outer ring are lowered, the push-up ridge shrinks, the transmission shaft, and the reverse shape reverses The reverse end of the leg is also lowered, and the grounding end is closed upward. At the same time, the clasp is held down and reset quickly, and it can quickly return to a cane shape by simply pressing the handshake. Useful for people with disabilities who can use only one hand, elderly people, and luggage. In addition, the structure is relatively simple, the number of parts is low, the cost is low, it is light and durable, there are few breakdowns, it is resistant to rain and snowfall, and the appearance is clean.

BEST MODE FOR CARRYING OUT THE INVENTION

A vertical moving body is fitted to the outside of the main column body, which has a plurality of inverted inverting legs at the lower end, and the vertical moving body that is pressed and contracted by the urging of the push-up ridge placed between them is pushed up and stretched. It can be returned to the position, and a handshake is fixed to the upper end of the vertical moving body, and a transmission shaft that conveys the movement is connected between the middle outer ring at the lower end and the reverse end of the reverse flipping leg to Invert the movement to the reverse leg. When the handshake is pushed, the ground contact end of one long end and the reverse end of the other short tip of the reverse-shaped reversing leg have a reversing function that moves up and down in opposite directions around an axis. , Both the vertically moving bodies are lowered together, the push-up ridge is shrunk, the transmission shaft and the reverse end of the reverse leg of the reverse shape are also lowered, and when the grounding end is closed while turning upward, the clasp is the main pillar The upper end is held down, and it can be reset quickly, returning to a cane shape. Also, when the button is pushed, the clasp is released, and the vertical moving body is pushed up and extended upward by the action of the push-up ridge, and the transmission shaft and the reversing end are also raised, the grounding end is lowered and opened, and the cane is supported instantly. .

  Vertical moving body with handshake, main pillar, push-up ridge, reverse-turning leg, reverse end, grounding end, transmission shaft, upper outer ring, button, clasp with ring spring, middle outer ring, lower outer ring, retaining A cane that can be quickly reset and self-supported by a gold catch, etc., and does not fall down. The upper outer ring 9 is fixed to the outer periphery of the upper and lower moving body 2 with a handshake 1, and a clasp 12 with a ring spring 13 is provided inside. Attached, fixed the middle outer ring 14 to the lower end, and fitted to the outside of the main column body 3 to be a vertically movable double cylinder structure, fixed the lower outer ring 17 to the outer periphery of the lower end of the main column body, The clasp receiver 16 is fixed to the upper end, and the middle outer ring, which is compressed by the urging of the push-up ridge 4 between the lower outer ring and the middle outer ring fixed to the vertical moving body, is pushed up and stretched by pushing up the vertical moving body. In addition, it is possible to return to the original position, and further, the lower outer ring is provided with a reverse inverting leg 5, With the outer ring and the plurality of transmission shafts 8, the reversing end 6 of the reversing reversing leg is connected to each other, and is composed of these features characterized by up-down movement and angle-changeable interlocking. Non-falling cane for disabled people who can reset and stand on their own.

The inverted reverse leg 5 provided on the lower outer ring so that it can be rotated is provided with a non-linear leg bent in a substantially “heavy” shape upside down or upside down. The right-handed “FIG. 3” and the left-handed “FIG. 19” have a short length from the tip of one inversion end 6 to the shaft, and a long length from the tip of the other grounding end 7 to the shaft. The length is more than 4 times that of the reversing end, and the distance between the axes of both ends is more than 4 times different. The movement of the grounding end and the reaction end moves opposite to each other with the shaft as a fulcrum. It also has a seesaw-like reversal function "Fig. 20" that rises when one goes up and the other goes down and the other goes down. In addition, the conventional self-supporting cane has legs that open radially in plan view, but the reverse-shaped inverted leg is flat. In this case, it is necessary to rotate and move sideways at right angles to the outer axis that is not parallel to the outer periphery, and the multiple grounding ends are shown in Fig. 9; It is further characterized by opening and closing. A plurality of transmission shafts 8 are connected to the middle outer ring 14 at the lower end of the vertically moving body from the reversing end of the reverse-shaped reversing leg, and can move up and down and change the angle, and the up and down movement of the vertically moving body and the reversing end are interlocked. .

Unlike the cane whose leg portion is opened and closed radially, like the conventional self-supporting cane, the reverse-vertical reversing leg mechanism has a non-radial, three-pronged shape. A unique feature is the unique turning operation that goes up, down, opens, and closes.
When the button is pressed, the clasp with the ring spring is released, and the middle outer ring and the vertical moving body are pushed up by the urging of the push-up ridge, and the transmission shaft and the reversing end are interlocked with each other. It moves upwards, and the multiple grounding ends open in a reverse manner in the form of a triple hook, while supporting the cane instantly to make it self-supporting, and conversely, when the handshake is pushed down, both the inner outer ring and the vertical moving body Also, the ridge of the push-up is shortened, the transmission shaft and the reversing end are also lowered together, and the grounding end is turned upside down while rotating in a three-sided manner, and at the same time, the clasp with a ring spring is held down and reset quickly. A cane that can be quickly reset and self-supported by one-handed operation, and is a non-falling cane.

The ring spring 13 of the clasp with a ring spring attached to the lower inner side of the upper outer ring is formed by a leaf spring and is formed in a substantially circular shape. It is also characterized by the fact that a clasp 12 whose shape is substantially T-shaped and whose lower end is bent at a right angle is fitted in the groove "Fig. 18". The clasp is located at the upper end of the vertical moving body. Can be moved horizontally by pressing the button 11 at one end of the clasp and releasing the hand, the ring spring is energized to return to the original position. A handshake is fixed to the upper part of the upper outer ring 9 at the upper end of the vertical moving body, and the lower part holds the clasp with a ring spring.
When the handshake is pushed, the clasp with the ring spring is lowered with the vertically moving body, the middle outer ring, the transmission shaft, the reversing end are also lowered, and the grounding end of the reverse reversing leg is turned up and closed in a three-piece shape, The lower ring spring clasp fits on the clasp receiver 16 fixed to the upper end of the inner main column body and automatically restrains it. [FIG. 16-B] When the clasps with ring springs move horizontally and the retaining clasps are released, the inner outer ring and the vertically moving body are pushed up by the urging of the push-up ridge, the transmission shaft and the reversing end are also raised, and the grounding end is reversed to three sides. The cane can stand on its own instantly by rotating in the reverse direction.
The clasp receiver 16 fixed to the upper end of the main column body is characterized by having an inclination and a recess at the upper part.
By pressing the handshake, the grounding end is closed by the above-mentioned series of operations, and at the same time, the clasp with the ring spring restrains the clasp holder and pressing the button releases the clasp with the ring spring. A cane that can be quickly reset and self-supported by a one-handed operation by a clasp with a ring spring, characterized in that the above-described series of operations is performed and is self-supporting.

To make it easier for left-handed people to use, "Figure 19" left-handed cane, with buttons, reverse-flip legs, and other positions placed left and right reversed,

As described above, with the simple operation of pushing the handshake downward with one hand, both the middle outer ring and the vertically moving body are lowered, the push-up ridge is also shortened, the transmission shaft, and the reverse end of the inverted leg is also lowered, and the grounding On the contrary, the end rises while turning around in a three-pronged form, closes vertically upward, and at the same time, a clasp with a ring spring holds down the clasp holder at the top of the main column that fits inside the vertical moving body, allowing a quick reset, The cane can be reset easily, even for disabled and elderly people with paralysis of one hand.
When the cane is to stand on its own, press the button on the clasp with your finger (Fig. 16-B, arrow D). The clasp with the ring spring moves horizontally and the clasp is released. The middle outer ring and the vertically moving body are pushed up by the force and extend upwards, as shown in Fig. 3, arrow C. However, it can be opened instantly to support the cane and become self-supporting, and more than half of the upper half of the main pillar body, which is hidden inside the vertical moving body, has many holes for the purpose of weight reduction. Vacant.

The present invention provides a cane obtained by improving the previous application “Japanese Patent Application No. 2005-354101, a cane that does not fall down” for the purpose of being easily used by a disabled person or an elderly person who is paralyzed with one hand.
When you press the button with your finger, the flipping leg will instantly open and become self-supporting, and with a simple operation of simply pushing the handshake downward with one hand, you can quickly open the free-standing leg. A cane that does not fall down that can be quickly reset and self-reliant with one-handed operation, characterized by resetting and returning to a cane usage.
