JPH09327315A - Self-traveling stick - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make a stick useful for the promotion of health as an aid to taking a walk by applying the constitution that the stick is formed to have a structure capable of self-traveling with the end thereof not parting from the road or floor. SOLUTION: A handle 1 is replaceable, and T-type, a triangular type or the like is mounted, depending on an application. Also, an expansion arm 2 is adjusted in length through a tightening element 3 for arm adjustment. A spring 9 has such a structure as capable of adjusting strength via cushioning the impact of the arm 2. Furthermore, a limit switch 21 operates, only when the roller of a limit shaft 20 enters the cam recess 19 of a cam 8 fitted to the support point of an arm mounting part. An electric motor is consequently stopped and a motor-driven brake is closed to stop a self-traveling stick. In this case, the arm 2 is formed to be freely collapsible back and forth via a support shaft 10. Also, a front drive wheel is caused to rotate on the operation of the electric motor via a chain. In addition, a rear wheel 18 is an idle wheel and made of a caster capable of freely moving right and left.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction equipment.

[0002]

2. Description of the Related Art A walking stick that helps walking
The cane is walked according to human power and moved away from the road or floor.

[0003]

This has the following disadvantages. Due to human power, the body is strained and may fall. The present invention has been made to eliminate this disadvantage.

[0004]

[Means for Solving the Problem] A board is provided at the tip of a walking stick, a wheel is provided under the board, and an electric motor and an electric brake for moving the wheel are provided above the board.

[0005]

The cam shown in FIG. 4 is provided at the fulcrum portion located at the tip of the cane, and the cane is tilted back and forth (see FIG. 5) to control the electric motor and to advance the board to assist walking.
Since the wheels are used, the wheels were fixed by an electric brake during stop so that they would not slip and fall.

[0006]

Embodiments of the present invention will be described below. (A) As the use of A and B in FIG. 5, one foot is used as a substitute for a crutch of a person who is incapacitated due to a fracture or illness, or as a walking aid. (B) As the use of A, C, and D in FIG. 5, it is used as an auxiliary device for a walk. It is used by people who do not have dogs or who are somehow embarrassed to walk alone. In addition, by changing the forward speed of the substrate, it is possible to walk at a fast speed such as fast walking, normal walking, and blunt walking. (C) As the use of E in FIG. 5, it is used as an auxiliary device for walking of the elderly.

[0007]

INDUSTRIAL APPLICABILITY The present invention is useful as a walking aid for people who have difficulty walking and as a walking aid in the modern society with many elderly people.

[Brief description of drawings]

FIG. 1 is a front front view of a self-propelled walking stick. 1 Handle can be replaced, and T type, triangular type, etc. are attached according to the application. Adjust the length of the 2 telescopic arms with the clamps for adjusting the 3 arms. 9 springs absorb the shock of the arm 7
Adjust the strength with.

FIG. 2 is a side view of a self-propelled walking stick. 20 in the 19 cam recess of 8 cams attached to 30 fulcrums of arm (cane) attachment
Only when the limit axis roller enters, the 21 limit switch operates, the 24 motor stops, the 25 electric brake closes, and the self-propelled walking stick stops. The arm has a structure that can be tilted back and forth freely via a 10-fulcrum shaft.

FIG. 3 is a plan view of a self-propelled walking stick. The 14 front-wheel drive wheels are chain driven by 24 electric motors. 18 The rear wheel is an idle wheel and has a structure in which it can freely move to the left and right by casters. 11 lights turn on at night. 29 Distance meter grasps the amount of exercise by displaying walking distance digitally.

FIG. 4 is a view showing a cam portion, where A is a front view and B is a side view. 19Cam recesses can be easily made by making a, b and c in large numbers and removing the mounting screws to make the necessary recesses.

FIG. 5 is a view showing walking and arms, and a 19-cam concave portion. A and B are figures showing substitution of a cane or a crutch when one leg is inconvenient. In the arm A position, the 19 cam recess is at the bottom and the 21 limit switch has been activated. When the wand is tilted to the arm B position, 19 comes off and 21 does not work.
(4) The electric motor rotates, and the self-propelled walking stick advances and stops until the arm is vertical to the A position. (Advancing by the width in which the cane is tilted forward) A, C, and D are diagrams when using a self-propelled walking stick (fast foot, normal foot, blunt foot) for a walk. Arm A position is stopped, 1 at arm C position (tilt the cane backward)
9 Cam concave part comes off 21 Limit switch does not work 24
The electric motor rotates and moves forward. When the walking is delayed compared to the self-propelled walking stick and the arm angle becomes lower than the D position, the roller of the 20 limit axis enters the recess of 1 cam (safety device) of 19 and the 21 limit switch operates and stops. E is a figure when a self-propelled walking stick (arm fixed) for assisting walking of an elderly person is used. Using the 31-arm fixing rod, fix the arm and move forward. In some cases, 32 tanks are filled with water from 33 water inlets to stabilize 12 substrates.

FIG. 6 is an electrical wiring diagram. Power source is 26 storage battery (dry type)
Can be charged with a 27 charger. Reference numeral 5 is an operation switch. The switch for 6 stairs is turned on when moving up and down the stairs, and even if the 21 limit switch is activated and the circuit is cut off, the circuit of 6 is alive, the 25 electric brake opens, the 24 electric motor rotates, and the self-propelled walking stick advances. The reason for using the brake is that it does not slip and fall. The 28-speed adjusting device changes the number of rotations of the electric motor, and switches the substrate speed to fast, normal or dull. 11 lights used at night.

Claims (2)

[Claims] 1. A walking stick having a structure in which the tip of the walking stick (stick) does not leave the road or floor surface and is self-propelled. 2. A walking stick having a structure in which a walking stick is provided with a cam, and the traveling is controlled by the cam.
