JP2003116941A - Lofstrand roller t-shaped stick - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve the problem that there is a little uneasiness in the operation of a handle while supporting his/her weight and further the range of persons capable of using a stick is limited when a grip is attached on the curved horizontal portion of the stick with four wheels. SOLUTION: By T-shaping the grip on the upper part of the stick with four wheels, the stick is made easy to use and further by attaching a cuff (forearm supporter) on the upper part thereof, even a person, who can not use a conventional T-shaped stick, can use the stick and self-support can be promoted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination of a walking stick and a walking vehicle.

[0002]

2. Description of the Related Art Conventional Lofstrand clutch, T-shaped cane, roller stick (cane with wheels 20)
00-126255), each of which was on the market alone.

[0003]

[Problems to be Solved by the Invention] Since the crutches bite into the side, it is difficult to get used to it, and a cup containing water cannot be carried. The Lofstrand clutch supports the forearm, so it is easy to apply weight and is rather convenient. The T-shaped cane is convenient because it is easy to put the weight on the center of the cane. However, in each case, the total weight is put on each step and the person with weak leg strength is burdened.
The roller stick does not fall down even if you release it, you can always carry your weight and carry a cup with water. We will combine these features into a walking aid vehicle that is even easier to walk.

[Means for Solving the Problems] Japanese Patent Publication No. 2000-1
Place the T-shaped part of the T-shaped cane on the upper part of the 26255 cane (roller stick) with four wheels, stand the pillar behind it, and attach the forearm support ring (called cuff) of Lofstrand to the upper part. For example, you can roll a wheel and walk stably with a considerable weight. This is named "Lofstrand Roller Tee".

BEST MODE FOR CARRYING OUT THE INVENTION In order to explain the present invention in an easy-to-understand manner, a triangular portion with four wheels will be described as a lower limb and an upper portion thereof will be described as an upper limb.

The description of the lower limbs will be made. It consists of a hollow pipe cane main body 1 and supporting rods 2, which have wheels 3 and 4 at their tips and hang down from the top to the back and forth, and links 5 and 6 that connect them on the lower side. Japanese Patent Laid-Open Publication 2000- that looks like a triangle with a bottom and can be folded.
In the 126255 cane (a cane with wheels), the bent part and the grip part are removed from the upper part of the cane body 1, leaving a little straight part a.

The upper limbs will be explained. A few horizontal holes d are drilled in the pipe c that has hung down below the T-shape 21, which is fixed by assembling the pipe into a T-shape. Align the position of the horizontal hole d in the height, and fix it by inserting a bolt or the like into the horizontal hole. The upper portion of the T-shape 21 is substantially horizontal, and the horizontal pipe b is a grip portion which is covered with rubber or the like and held by a hand.

At the lower part of the rising pipe 22, there is a horizontal pipe f protruding laterally in an L-shape, a tip end thereof has a cut face g cut obliquely, and a cut face h matching the cut face g is provided at the tip thereof. There is a nut 23, which has a long bolt 24 connecting them. When the long pipe 24 is tightened with the standing pipe 22 standing upright, the nut 23 slides on the slanted surface and expands inward to expand the horizontal pipe b. The rising pipe 22 is fixed by tightening the inner diameter of b. When the cuff 30 is unnecessary, it can be easily removed by loosening the long bolt 24. A horizontal hole i is provided on the upper portion of the rising pipe 22 so as to match with several horizontal holes j of the cuff height adjusting pipe 25.

The cuff height adjusting pipe 25 is provided with a cylindrical cuff 30 through which an arm can pass, and a rib 31 protruding from the cylinder is attached by a pin 32 to the cuff height adjusting pipe 25 so that the cuff conforms to the angle of the arm. There are several lateral holes j in the lower part, and one of the lateral holes j and the lateral hole i of the rising pipe are combined to set the height position of the cuff 30 appropriately, and bolts or the like are fixed to the lateral holes.

A brake is applied to the cane (clutch). Grip the brake lever 13 and brake wire 1
2 is pulled, the front side of the brake main body 11 pivotally attached to the support rod 2 by the pin 12 is pulled up, and the blades m of the brake main body that are spread over the wheel on the rear side sandwiching the pin 12 move the wheel. It even applies pressure to apply the brakes.

If necessary, this brake is a so-called parking brake that can be placed with the brake applied even when the hand is released. 4 and 5 are detailed views thereof. In the figure, the solid body p is pierced at a position facing the tip of the brake lever 13 at the center of the horizontal pipe b (grip) to open a lateral hole k, and the tip of the string 14 is passed from both sides to the loop o of the string. Make and hook the tip of the brake lever on the wheel. The two-dot chain line of the brake lever 13 in FIG. 5 shows the position of the brake lever when the brake is released. The size of the ring is adjusted by pulling the string from both sides so that the brake can be applied, and the string 14 is tightened with the screw q of the screw that abuts the lateral hole k at a right angle to fix the string so that it does not slip.

To use it, pass the arm through the cuff 30 from above, hold it just above T of the horizontal pipe b (clip), put it on your waist as close as possible to your weight, and sometimes lean the cane and poke it. If you walk with the sensation of pushing with your waist instead of moving with your arms, it will be easier to walk. When the cuff is not needed, either remove it or drop the cuff down and use it in a T-shape.

The effect is that when the forearm is passed through the cylindrical cuff and the weight is gripped and the weight is applied, the effect of the conventional T-shaped cane (supporting the weight on the T) and the effect of the loft strand clutch (supporting the arm are supported). In addition to the effect of stopping the fluctuation and stabilizing) and the effect of crutches (supporting leg strength), you can walk with your weight on the cane, so the total weight does not fall on your legs with each step, so there is a recurrent effect With the less strain on the knees and hips that come out, people with a level that used to be bedridden can now enjoy the joy of being able to walk independently.
