Description

The present invention relates to a self-supporting cane with casters having wheels attached to the tip of the cane.

Conventionally, a cane that assists when walking has a problem in safety because some users walk or drag the cane while repeatedly poking the ground with the tip of the cane step by step.

A cane with a roller has been devised to improve the safety of walking and auxiliary canes, but there are problems related to safety.

Utility Model Registration No. 005456 Japanese Unexamined Patent Publication No. 2014-200380

Walking while repeatedly poking the cane makes it difficult to use the cane because the legs and waist cannot withstand the walking, but solving these problems is a heavy burden, so the cane is It is difficult to reduce the burden on the user.

The cane with casters requires the user to manually apply the brakes, and the two auxiliary legs will fulfill that role. When the auxiliary legs in front of the wheels advance too far, pull the grip toward you to touch the ground. , The mechanism is such that the brake is applied.

Generally, a cane assists walking by touching the cane to the ground step by step, but it is not necessary to repeat the cane back and forth by attaching casters, so feel free to enjoy going out. Can be done.

The shaft 2 is provided with several adjustment holes 5 that penetrate from the side surfaces of the outer cylinder and the inner cylinder, and the length of the cane is adjusted by inserting and fixing the locking pin 7 from the outer cylinder so that the pin head 6 does not come off. It is fixed in the state shown in FIG. Also, if you push the pin end strongly, the locking pin will come off.

The shaft A has the cane on the front side as much as possible by angling the shafts 2 and 3 in front of the vertical cane, so that the cane with wheels can move smoothly and there is less anxiety.
For the tires of the wheels, suitable ones such as synthetic rubber such as urethane rubber and silicon rubber are used, and natural rubber is also acceptable.

Grip 1 uses a shovel handle type, which is easy to grip, but the ease of holding reduces the burden on the wrist and increases the time to enjoy going out.

The cane with casters stabilizes the center of gravity of the body even when walking on flat ground and slopes, reduces the burden on the wrist joints, and walks normally without making unnecessary movements while holding the cane and extending it from the bent elbow state. It is a cane that can be used.

The lengths of the shafts 2 and 3 can be adjusted by moving the outer cylinder up and down through the through holes that penetrate both the outer cylinder and the inner cylinder and fixing it with the locking pin 7 at a position that matches the height of the user. ing.

It is a side view of this invention and the assumed view at the time of braking. It is a front view of this invention. It is a front view of the two-handed cane of this invention. It is sectional drawing of the outer cylinder and the inner cylinder of this invention.

Hereinafter, embodiments of the present invention will be described.
(B) The auxiliary cane A with casters of the present invention has an existing caster provided at the tip of the shaft 4, and the cane equipped with two auxiliary legs has a shape configuration as a cane that is safe and convenient for the user. It has become.
(B) It is an accessory part that serves as a stopper by attaching the auxiliary legs 8 that are integrally connected to the upper shaft 4 of the wheel 11 on the left and right.
(C) When the auxiliary cane A is pulled toward the front from the vertical posture, the auxiliary leg 8 is provided so that the wheel 11 comes into contact with the ground and the brake is applied.
(D) There are two types of grip handle 1 (grip), one-handed grip and two-handed grip, and two types are prepared so that some users are worried about the cane with wheels.
(E) An adjustment hole 5 is provided in which both the outer cylinder 2 and the inner cylinder 3 of the shaft are overlapped and penetrated.
(F) Since the locking pin 7 can be pulled out and the position can be freely changed, when adjusting the length of the auxiliary cane, first align the holes of the shafts 2 and 3 and then engage with the adjusting hole 5 facing up. Insert the stop pin from above.
(G) A shallow groove B is provided in the center of the left and right of the inner through hole of the outer cylinder 2 of the shaft.
(H) Convex muscles C are provided at the center of the left and right through holes on the outside of the inner cylinder 3 of the shaft.
(I) When the concave groove B and the convex muscle C of the outer cylinder 2 and the inner cylinder 3 match, the locking pin can easily pass through. To pull out the pin, push in the lower part of the pin butt and pull out the pin head 6.
(N) The configuration in which the wheel 11 is attached to the tip of the cane of the shaft 4 is fixed by screwing the upper screw 10a of the caster into the female screw 4a of the lower part of the shaft 4.
(L) The shafts 2 and 3 are tilted 5 to 10 degrees backward from the vertical of the shafts 1 and 4. By making the entire cane vertical, when the user walks, he / she can safely proceed so as not to lean forward.
The present invention has the above configuration.
When using the present invention, place the palm of your hand lightly on the grip of a self-supporting cane with casters in the same way as when using a general cane, turn the wheel 11 in the direction of travel, and slowly push the cane body A forward. To do. This movement is repeated to walk.
Elderly people and disabled people who had a weak grip and had difficulty walking with a general cane can now walk while ensuring safety using a self-supporting cane with casters.
