Besides, an inverse L-shaped stopper 5 is fixed at the lower part of a handle 2, a spring presser 3 is provided below the opposite side, and a compressing spring 4 is fitted here. Further, the handle 2 is mounted on the handle fitting seat 6, and the mobile object 1 is fitted to banisters 9 of which the cross-section is rectangularly shaped. When the handle 2 is grasped and pushed up along the banisters 9 in the case of use such as going up the stairs, for example, the stopper 5 is canceled, the roller 12 is turned and the mobile object 1 is pushed up.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention attaches a device equipped with a handle that can freely slide on a handrail of a staircase to prevent falling and assist the rise and fall of the staircase, and ascends and descends the staircase while grasping the handlebar. It concerns security equipment for stairs.

[0002]

2. Description of the Related Art Conventionally, there is an escalator for assisting climbing stairs. In addition, handrails installed on the side walls of the stairs at the same slope as the stairs and slips on the treads were used to prevent falls.
In addition, a handrail that incorporates lighting and an electric handrail have been devised.

[0003]

[Problems to be Solved by the Invention]

(A) It was difficult to install an escalator in an ordinary home. (B) With the conventional handrails for stairs, there was a lot of danger because the handrails had to be released for each step when going up and down. (C) The position of the hand when climbing the stairs by grasping the handrail is above the chest, while the position of the hand when descending with high risk is below the waist, so the posture tilts forward. It was dangerous for the elderly with a bent waist. (D) In the conventional handrail, since it is a rod extending in the same direction as the body, it has a function of stabilizing the body, but it is not suitable for pulling up or receiving the body. In order to eliminate these drawbacks, the present invention fits a device with a handle to the handrail of the stairs and moves up and down while grasping the handle, so that it is possible to move up and down in a safe posture without releasing the hand and step on by any chance. It is intended to be a safety device for climbing stairs that can be held by the handle to support the body when removed.

[0004]

In order to achieve the above object, the fall prevention device of the present invention is used by being fitted on a side wall of a staircase and a handrail installed at the same inclination as the staircase. A hole for receiving a stopper is made in the upper surface of a hollow C-shaped moving body having a side opening or a side surface opening on the lower surface of the moving body, and a reverse rotation prevention with a reverse rotation preventing claw is provided at the upper end of the upper surface of the moving body. A claw roller is attached, and two handle attachment seats are fixed to the substantially central portion of the upper surface of the moving body. And at the tip,
An inverted L-shaped stopper with a stopper rubber attached is fixed to the lower part of a rod-shaped or T-shaped ring-shaped handle, and a spring retainer is attached below the handle on the opposite side, and a handle with a compression spring is attached to it. Mount it on the handle mount so that it can move. Then, a side surface stopper rubber is attached to the inner surface of the upper portion of the side surface opening (7) of the moving body so as to be horizontally long to the length of the moving body. A fall prevention device in which a moving body constructed in this manner is fitted into a handrail having a substantially rectangular cross section and fitted on the handrail of a staircase.

Operation As described above, when using this to climb stairs, the handle is grasped and pushed upward along the handrail to release the stopper, the roller rotates and the moving body moves slightly upward. Pushed up to. If you pull the handle toward you, a stopper will be applied and you will row a boat, and your arm will pull up your body. When going down the stairs, pull the bar handle toward you, or push the ring-shaped handle down, and while braking with the rubber roller, go downstairs along the handrail. Should you step out of the stairs, you will be caught in the handle to prevent it from falling.

[0006]

EXAMPLES Examples of the present invention will be described. Since this device is a safety device for the purpose of preventing falling from the stairs and assisting in raising and lowering, it is preferable that the handle and the moving body are made of durable metal. Two pieces of handle attaching seats for attaching the handle to the central portion of the upper surface of the substantially C-shaped moving body are welded in parallel, and a stopper hole is formed in the rear portion. Attach a rubber roller with a reverse rotation prevention claw to the front end of the moving body so that it rotates only in the forward direction. For the handle, use a short rod-shaped handle with a grip, or a T-shaped handle with a ring-shaped top. Attach a reverse L-shaped stopper with a rubber tip to the bottom of the handle, attach a spring retainer below the handle on the opposite side, put the handle in the handle attachment seat, and compress between the spring retainer and the moving body. Insert the spring and bolt it. At this time, the handle can move freely back and forth. A stopper rubber with a thin length of the moving body is attached to the inside of the upper portion of the side opening. Also, the shape of the handrail is almost the same as the shape of the opening of the moving body as shown in FIGS.
When inserted, the upper and lower gaps are 2 to 3 mm in contact with the roller, and the horizontal gap is increased. By doing this, when the handle is pushed up, the moving body does not generate leverage and slides smoothly, and when the handle is laid down sideways, the moving body tilts and leverage is exerted. Depending on where the handrail is installed on the stairs, if there is a handrail on the right side, the side opening of the moving body will be on the right side as shown in Fig. 3.
When the left handrail is on the left side, or when the handrail is installed on the stairs and the fixed body of the handrail is on the lower side, the side opening is on the lower side as shown in FIG. Since the present invention is configured as described above, when the hand is released from the handle, the handle is pushed by the force of the spring as shown in FIG. 2, and the stopper pushes the handrail. As a result, it does not slide down from the upper part of the inclined handrail.
Further, even in the case where the columnar handrail is a circular moving body, it can be prevented from slipping down and falling sideways. As shown in FIG. 2, when the handle is grasped and pushed upward in the direction B above the stairs, the spring is compressed and the stopper is raised, and the roller with the reverse rotation preventing claw is rotated to move the device lightly. Pull the handle in direction A to engage the stopper. The stopper is stronger as the pulling force increases with leverage. When going down the stairs, push the rod handle downward while tilting it in the direction B as shown in Fig. 2, and push the ring-shaped handle as shown in Fig. 5 downward while pushing it in the direction B. Therefore, it does not rotate and acts as a brake. When the foot is stepped off from the footboard, the stopper is applied by tilting the handle forward, and when the handle is tilted sideways, the side stopper rubber (8) is pressed against the handrail to stop the moving body.

[0007]

The present invention is based on the principle of leverage, and the stopper can be easily removed without fail. Also, it does not take up space even on narrow stairs. When you go up the stairs, it has the same effect as having someone pull your hand, and when you step down, put your weight on the steering wheel, and support yourself to get off the brakes so you can get off safely. Also, since the stairs always descend when they rise, it can be used for both climbing and descending. Should it fall from the head, the stopper of the handle will be applied, and if it falls from the foot, the stopper of the side surface of the moving body will be applied to prevent the fall.
