SUMMARY OF THE INVENTION A stair fall prevention device according to the present invention, which is intended to solve the above-mentioned problems, is provided with a fixed guide member on the side of the stairs, and a fixed guide member is provided on the stairs from the uppermost step. A fall prevention device on a staircase incorporating a body holding member that can freely move back and forth to a lower stage and incorporating a lock mechanism that stops the forward and backward movement of the body holding member in an emergency when an excessive load is applied to the body holding member ,
The body holding member includes a belt having an arm ring at a free end.
And the guide member moves the belt together with the lock mechanism.
It is characterized in that it is a pillar stored in an empty space .

[0005]

[Action] fall prevention device in such a staircase, Yu built into the fixed guide member provided on the side of the staircase
If lift the stairs after having to hold the arm of the lifting's body holding member comprises a belt having a Udewa to end the lifting person on their own, the body support member locking unit the belt
The guide member, which is composed of the pillars housed in the hollow part together with the structure, can freely move back and forth from the uppermost stage to the lowermost stage of the stairs. (1) In an emergency when the lifted person steps off the stairs, a sudden load applied to the body holding member activates the locking mechanism incorporated in the guide member via the body holding member to move the body holding member itself back and forth. Since it is stopped, the person to be lifted up and down can be properly prevented from falling downstairs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in FIGS. In FIG. 1, reference numeral 1 denotes a fixed guide member provided on the side of the stairs, and the guide member 1 is a hollow column on the uppermost side of the stairs. Two
In the body holding member incorporated in the guide member 1 so that it can freely move forward and backward from the top of the stairs up to the bottom, this
The body-holding member 2 comprises a belt mechanism 4 having a base portion connected to a lock mechanism 3 having a mechanism similar to that of an automobile seat belt, and an arm ring 5 provided at the tip of the belt mechanism.
Both of them are housed in the hollow part of the column as the guide member 1 and only the arm ring 5 is exposed from the upper end of the column.

As shown in FIG. 2, the lock mechanism 3 is attached to the belt winding roller 6 and self-locks in an emergency to stop the rotation of the belt winding roller 6 and stop the advance of the belt 4. As described above, the specific mechanism may be the same as that of various known seat belts for automobiles, and therefore will be omitted.

A column 7 is provided at the side of the bottom of the stairs, and a hook 8 for hooking the arm ring 5 is attached to the column 7. In this embodiment, the body holding members 2 are provided on both sides of the stairs so that a plurality of people can use the stairs at the same time, but it goes without saying that they may be provided on only one side.

When the stairs are constructed as described above, when the stairs are going up and down, they are guided by a fixed guide member 1 provided on the side of the stairs and can freely move back and forth from the uppermost stage to the lowermost stage of the stairs. If the arm of the person to be lifted is passed through the arm ring 5 at the free end of the belt 4 serving as the holding member 2 and the person to be lifted ascends and descends the stairs by himself / herself, the belt 4 is moved from the uppermost stage to the lowermost stage of the stairs in accordance with the elevation. Since it can be freely moved back and forth to the stairs, there is no problem in climbing the stairs for the person to be lifted. A sudden load is applied to the belt 4, and the belt 4 tries to be suddenly sent out.

However, since the guide member 1 incorporates the lock mechanism 3 for stopping the forward / backward movement of the body holding member 2 in an emergency in which an excessive load is applied to the body holding member 2, the belt 4 is attached to the belt 4 via the arm ring 5. The lock mechanism 3 self-locks by the applied load to stop the belt 4 from advancing. Therefore, the arm ring 5 at the tip of the body holding member 2 securely holds the lifted person and the lifted person falls downstairs. To prevent that.

The body holding member 2 has a belt 4 having an arm ring 5 at its free end, and the belt 4 is housed together with the lock mechanism 3 in the hollow portion of the column as the guide member 1 .
Then, a safety device with a brake connected to the body holding member is a ladder
Exposed to always move along the rails built into
It has a better appearance than the ones that have been put up, and the body is on the stairs of a general house.
It can be installed neatly, has a very simple structure, and can be provided at low cost.

[0012]

As is apparent from the above description, the present invention is provided with a fixed guide member on the side of the stairs, and freely moves back and forth from the top of the stairs to the bottom of the stairs as the lifted person moves up and down. In addition to incorporating a body holding member that can be used, a lock mechanism is incorporated in the guide member so as to lock the movement of the body holding member when an excessive load is applied to the body holding member. If you move the stairs up and down, and the person to be lifted holds a part of his / her body on the body holding member when going up and down the stairs, the person to be lifted will go downstairs even if he / she steps away from the step. Falling is accurately prevented.

In particular, according to the present invention, the body holding member has the arm at the free end.
It has a belt with a ring inside
The belt is stored in the empty part together with the lock mechanism.
And, it looks good, and it should be built into the stairs of a general house.
Ru Der what can.

Therefore, according to the present invention, it is possible to accurately prevent the person from falling downstairs even if he / she accidentally steps out of the stairs. However, since there is no complicated mechanism such as a drive source, it has the advantage that it can be installed in an existing house at a low cost and has practical value as a fall prevention device on stairs that solved the problems of conventional stairs. It is a thing.
