Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a conventional cane, a supporting rod, and a roller attached to the tip of each of the supporting rods to be a rolling cane, which automatically folds in a crowded place. It is designed to support the body and to carry simple luggage.

[0002]

2. Description of the Related Art Conventionally, a cane has been constructed on the concept that the tip of a stick touches the ground. In other words, hold one upper part of one rod (including the pipe) with one hand, put the other lower part on the ground, remove the walking stick from the ground every time you walk, and walk forward to support your body. It was an aid to walking. In order to assist walking, there is a walker in addition to the walking stick.The walker has rollers attached to the lower four sides so that the body can always be supported, and a person stands in the center of the four-way roller and is integrated with the roller. He supported his body by hanging his arms and hands on the upper frame, and rolled the rollers to move. This four-way roller is a three-way roller to prevent it from falling, a person stands in the center, sets up a frame on one side only on one side, supports the body with arms and hands on the upper frame, and rolls the roller so that it can move JP-A-61-34342 discloses a conventional technique. This is used in special places such as hospitals and facility training centers and cannot be used on public roads. Therefore, the convenience of the cane considered in the invention is not amplified. By the way, there are publicly known prior arts that can be used on public roads, which are Japanese Patent Laid-Open Nos. 64-6931-6932, 64-14018-14019, 4-42822, and 4-124141, but these also have problems. It will be described step by step. 64-963 of these technologies
1 is fixed and cannot be folded. In the case of Sho 64-9632, the horizontal bar 4 can be detached and folded at the position 5 of the cane body a in FIGS. 1 and 2, and in FIG. 3, one end of the horizontal bar 4'b is divided into the stabilizer legs 1. The groove is slid and lifted upward so that it can be folded, but both are inconvenient for the following reasons. Originally, the cane is used by people with poor waists such as the hips and knees, and those that must bend their hips and lift the lower part to fold depending on the place and case are used. Use with the inside unfolded, and fold only when storing. In a crowded place, for example, in a market, on a train, or on a bus, people around them are annoyed and troubled. Similarly, the prior art Sho 64-14018-14019,
Also, when folding flat 4-42822 and flat 4-124141, the hips must be bent deeply one by one, and normally they are used without doing such an operation, leaving them uncomfortable in a crowded place. I had a problem that I would use it while hanging it.

[0003]

[Problems to be solved by the invention] The cane can be used in a crowded place or on a public road. However, with a conventional cane, each time you walk, you balance your body, move the cane away from the ground, move to a position where you can reach the other side in time with walking, and lean on the cane to move your body. Therefore, while keeping the cane off the ground, you have to balance with your own foot, which is anxious for people who need the cane, such as sick people, the elderly, and the physically handicapped, and you need to keep your back deep. There were some people who had to bend or take an unusual shape. Therefore, if you can move while always supporting the body without lifting the cane and in a crowded place, it can be automatically folded small and used as it is, if there is a little place it can be automatically expanded and used Very convenient and solves the problem.

[0004]

[Means for solving the problem] Lift the cane step by step,
And it is good to get out of the preemptive feeling of being a thing to wear, and to attach a roller to the tip of the cane and always lean against the rolled cane to walk, but only to attach the roller to the tip of the cane and roll it Since it is also unstable, I thought that it would be better to attach a rod (called a support rod) that extends diagonally from the middle of the cane to the ground and supports the cane so that the cane, the support rod and the ground form a triangle. Naturally, the roller is also attached to the tip of the support rod. By the way, the present invention was developed from a cane, and it has two front wheels and two rear wheels on one side of a person.
(This is a little unstable when the cane does not fall over immediately when you release your hand. It may be a little unstable.) The width is narrow, and the cane spreads in the direction of travel. However, since it is inconvenient when it is spread out and it is inconvenient when going up and down stairs, it is designed so that it will automatically fold when tilted or lifted a little, so you can reach it as it is or roll it. , It is an amplification of the role of a cane that can be used in a small place on one side of a person. In addition, a brake device designed to prevent danger on slopes was also installed. The name is called "roller stick".

Detailed Description of the Invention

[0001]

The invention relates to the conventional one of cane, and one of the support bars, and cane rolling by attaching a roller to their tips, junk in the naturally be folded up so the place to be crowded It avoids it, supports the body, and can carry simple luggage.

[0002]

2. Description of the Related Art Heretofore, a cane has been constructed on the concept of landing on the ground with the tip of a rod. In other words, one rod (including pipe)
One hand grasps the upper part of one hand with the hand, and the other end wears the lower part on the ground. With each walking, the staff is released from the ground. In order to assist walking, there is a walker in addition to the walking stick.The walker has rollers attached to the lower four sides so that the body can always be supported, and a person stands in the center of the four-way roller and is integrated with the roller. Support your body by hanging your arms and hands on the upper frame
Roller was moving. Use this four-way roller as a three-way roller to prevent it from falling,
There is a conventional technique disclosed in Japanese Patent Laid-Open No. 61-34342 in which a frame is erected only on one side and one side is supported, and an upper frame is supported by an arm or a hand to support a body and a roller can be moved. This is used in special places such as hospitals and facility training centers and cannot be used on public roads. Therefore, the convenience of the cane considered in the invention is not amplified. By the way, in the prior art that can be used on public roads, Japanese Patent Laid-Open Publication Nos. 64-6931 to 6932,
64-14018 to 14019, Hei 4-42822,
There is a 4-124141. However, these also had problems. It will be described step by step. 64-96 of these technologies
31 is a fixed type and cannot be folded. 64-9632
In Fig. 1 and Fig. 2, the horizontal bar 4 can be detached and folded at the position 5 of the cane body a, and in Fig. 3, one end of the horizontal bar 4'b is slid in the split groove of the stabilizing leg 1. It is possible to fold it by lifting it upwards, but both are inconvenient for the following reasons. Originally, the cane is used by people with poor waists such as the waist and knees, and it is difficult to bend the waist and lift the lower part to fold it depending on the place and case . Therefore, use it while unfolding it, and fold it only when storing it. In a crowded place, for example, in a market, on a train, or on a bus, people around them are annoyed and troubled. Similarly, the prior art Sho 64-14018 to 1401
9 and flat 4-42822 and flat 4-124141 also have to bend the hips deeply when folding, and normally they are used without doing such a movement,
In a crowded place, there was a problem that it was used while annoying people.

[0003]

The cane can be used in crowded places and on public roads. However, with a conventional cane, each time you walk, you balance your body, move the cane away from the ground, move to a position where you can reach the other side in time with walking, and lean on the cane to move your body. Therefore, while keeping the cane off the ground, you have to balance with your own foot, which is anxious for people who need the cane, such as sick people, the elderly, and the physically handicapped, and you need to keep your back deep. There were some people who had to bend or take an unusual shape. Therefore, it is possible to move while supporting the body without lifting the cane and to fold it naturally in a crowded place so that it can be used while folded, and if there is a little place it will be natural.
It's very convenient if you spread it to and use it, and the problem is solved.

[0004]

[Means for solving the problem] Lift the cane step by step,
And it is good to get out of the preemptive feeling of being a thing to wear, and to attach a roller to the tip of the cane and always lean against the rolled cane to walk, but only to attach the roller to the tip of the cane and roll it Since it is also unstable, I thought that it would be better to attach a rod (called a support rod) that extends diagonally from the middle of the cane to the ground and supports the cane so that the cane, the support rod and the ground form a triangle. Naturally, the roller is also attached to the tip of the support rod. By the way, the present invention was developed from a cane, and it has two front wheels and two rear wheels on one side of a person.
(This is a little unstable when the cane does not fall over immediately when you release your hand. It may be a little unstable.) The width is narrow, and the cane spreads in the direction of travel. However, since it is inconvenient when it is spread out and in a crowded place or when climbing up and down stairs, it is designed so that it will fold naturally when tilted or lifted there, so you can arrive and roll as it is, To the last
This is an amplification of the role of a cane that can be used in small places on the side . In addition, a brake device designed to prevent danger on slopes was also installed. The name is called "roller stick".

[0005]

[0006]

EXAMPLE FIG . 1 is a side view of the roller stick, and FIG .
Is a front view, and FIG. 3 is a side view in a folded state. Cane 1
Is a hollow pipe, the upper end of which is bent at about 90 ° to 120 ° to form a handle 17, and the rollers 3 are attached to both sides of the lower end by pin shafts 14, respectively, and the cane 1 freely rotates at two places in the middle. As can be seen, the cane 1 is attached to the shaft as the bracket 5 and the bracket 6 as the outer ring, and the bracket 5 is provided with a protruding portion.
The support rod 2 of the hollow pipe is pivotally attached to the protrusion by the pin shaft 8, the protrusion is also provided on the bracket 6, and one end of the link 12 is pivotally attached to the protrusion by the pin shaft 9, and the lower end of the support rod 2 is attached. The rollers 4 are attached to both sides of the support shafts by the pin shafts 15, the brackets 7 are fixed in the middle of the support rods, and the brackets 7 are also provided with protrusions. wear and, axially wearing link 12 and link 13 by a pin shaft 10, supported
Make sure that the rod does not spread beyond the length of the link, and if the pin axes of the brackets 5, 6 and 7 are tied together, form a triangle with a base, and the pin shaft 9 etc. (return spring as described later). The place where 18 is installed can be changed, etc.), and a return spring 18 is wound around it, and when the roller is separated from the ground (when the roller stick is lifted or tilted in the front-back direction), the return spring 18 is used.
The links are naturally folded so that they can be folded as shown in FIG. The return location of the spring 18 well even pin shaft 11 even pin shaft 10 may be connected by a spring pulling the pin shaft 8 and the pin shaft 10. In addition, stock
Link 12 or link 1 with a pin or ledge
Attach to 3 and bend a little before the link stretches straight
To stop in a standing state (small bear that has been folded)
For example, if you remove the wheels from the ground,
Although it is powerful, it folds automatically (naturally). Place
Therefore, it may be dangerous if the roller rolls on a slope, so install a brake device. A brake lever 19 is attached near the handle 17, a swing arm 23 is pivotally attached to a support rod 2 near the roller side by a pin shaft 24, and one end of the swing arm 23 simultaneously holds the outer diameters of the rollers 4 on both sides. Thus, the brake piece 25 is extended to the outside, and the other end is connected to the brake lever 19 by a wire 22 that passes through the outer 20. If the upper grip 17 and the brake lever 19 are gripped so as to be sandwiched, the brake is applied. Is done. You can attach this flexure device to the cane 1 side
Or may be attached to both sides. It should be noted that the front and rear wheels may be one wheel, but it is better to use four wheels so that they can stand without falling down even if they release their hands. Furthermore, in order to carry some luggage, the roller stick is provided with a luggage rack 16 having a U-shape widened on the upper portion of the bracket 5 for convenience .

[0007]

As a walking stick, the walking stick can be walked while always leaning on the roller stick having a width and a size that does not interfere with only the side of the person, and in a crowded place, tilt the roller stick slightly backward or forward. When the front or rear wheels are released from the ground, they naturally fold and become smaller, and can be worn as they are or rolled. If it is more dangerous, the brakes can be applied and safety is taken into consideration. According to the experiment, the waist is bent
When the elderly people hang their luggage with their hands and walk, their waist bends further
Therefore , it was said that it is difficult to walk, but with this roller stick, you can stand up and stretch your back without walking, and it will be easier and more fun to walk.
Was to say. Furthermore, because it is a four-wheeled,
Roller cane stand alone, somewhere with one cane
I had to find a place to lean against
But if you fall, you have to bend down and pick up
However, it has also disappeared, which is convenient for users .
