JP2003321180A - Electric safe lowering device with grip handle when descending staircase - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To prevent serious accidents such as bone fracture from, if wrongly, occurring to those who are old, because their nerves become dull, and they feel fear and anxiety for descending staircases. <P>SOLUTION: At the time of descending the staircases, when a person slides a hand along a guard rail or changes a hand, only a supporting action is required for an accidental incident such as slippage of feet. Because the person grips a grip handle firmly, and descends while turning on switches of start and stop according to the movement of feet from the descending start time, this invention can cope with accidental incidents safely. <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field that belongs to vertical moving means of a human body using various functions by electric power.

[0002]

2. Description of the Related Art As an upper and lower device for an existing human body, it receives all of the human body, including elevators and escalators.
It has a mechanism that moves up and down.

[0003]

[Problems to be Solved by the Invention] When it is called an aging society, the oldest person is most troubled by going up and down stairs. of,
The challenge is to be able to prevent accidents.

[0004]

[Means for solving the problem] When going down from the upper floor, slide your hand on the handrail, step off when you go down, and the old man's reflexes weaken, and you can not support your weight in a moment.
The handrail is sloping along the stairs, so the hand holding the handrail is the opposite of the handrail and is peeled off, so as to prevent the worst situation called falling, The present invention, instead of the handrail, upright the Nigiri handle,
From the start, you can grasp the grip tightly and go down, so you can prevent accidents when descending.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION For people living in high-rise houses without elevators to age and carry luggage and climb stairs,
It is difficult, and it takes a huge amount of money to install an elevator. Recently, a patent has been published, Japanese Patent Application No. 199368, and an electric human body pulling device incorporated in a handrail is used to take off the foot when descending. In order to prevent troubles, I made the nigiri pattern upright so that I could hold it firmly from the start. In addition, you can operate the switches one by one according to your physical condition to achieve a safe descent.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a state in which the present invention is attached to a side surface of a staircase. The handrail 1 is a metal square pipe, the side surface is parallel to the pipe material side surface, and the guide passage is provided on the side surface of the elevating body 10. There are 37. The storage case for the motor 4 and other related members is directly fixed to one end of the handrail 1, but it may be set at another position.

As shown in FIGS. 2 and 3, the elevator body 10 has four pulley shafts 5 fixed at four corners, and the pulleys 11 and 8 can be lifted and kept smooth. One end of the scrib shaft 3 is fixed to the handrail 1, inside the material, and at a central position by the motor spindle and the collar 35, and the other end is a bearing hole 33.
In addition, the nut 34 corresponding to the screw shaft is welded to the lifting body 10, and the lifting body 1 is started by starting the motor.
0 moves up and down diagonally.

As shown in FIG. 2, the upper surface of the lifting body 10 goes out of the guide passage of the handrail 1, bent 90 degrees upward, and further bent at both ends to insert the metal pipe 12 of the grip handle 2. The portion of the nigiri handle 2 which is bent 90 degrees is made to be undulating, and when standing upright, it is locked by the pin 6 mounted on the cover plate 13.

As shown in FIG. 3, when the lifting / lowering body 10 obliquely rises and reaches the upper end portion, the ball material 18 fixed to the terminal end portion of the wire 17 stretched around the power source switching plate 14 is pressed, and the power source switching plate 14 is pushed. Is turned through the resistance of the spring 16, the current contact 21 is changed to 20, and the motor 4 is changed from the forward rotation to the reverse rotation. Therefore, the lifting / lowering body 10 is in the descending posture and descends to approach the starting end position. , The lifting body 10 directly receives the power switching plate 14 from the resistance of the spring 6 to change the current contact from 20 to 21, that is, automatically switching. This function is the pressing operation of the switch button of the handle 2 Then, using the time of descent, you will descend safely.

Push switch mechanism of the push button 7, FIG.
It is shown in Figure 4. In the lower part of the handrail 1 shown in FIG.
One end of the extra fine stainless wire or the like 26 is fixed to the upper end position of the handrail 1 and the other end is stretched and connected to the actuator of the micro switch. At this time, the convex portion of the switch 15 is pushed by the spring 34 and turned on. Or?

Next, FIG. 4 shows that the length of the stretched wire 26 is bent by the strength of the spring 27 so that the switch 15 becomes OF. The shaft 23 of the grip handle 2, which is fixed to the push button 7, has the axis of the shaft 23 which is a bend of the metal pipe 12 and a ball 24 in the position.
Press, and the actuating piece 25 at the tip will move the switch switching piece 2
When the upper part of 8 is pushed against the spring 27, the bent wire 26 becomes a straight line, the switch 15 is turned on, and the motor is started.

In FIG. 5, a bevel gear 29 is fixed to the main shaft of the motor 4, the bevel gear and the sprocket 30 are made the same body, and the sprocket 30 is mounted in the function case 36 by the shaft member 32. The chain 31 is also installed at the upper end of the chain, and the chain 31 is stretched between both sprockets, and the lifting body 10 is mounted on the chain 31.

[Effect of the Invention] When going down the stairs, everyone feels fear when high, and anxiety when low. The present invention, from the start, hold the grip handle tightly, press the switch button,
After confirming safety, you can go down, and even if you have an accident such as stepping on or stepping on, you can respond.
