Abstract

PURPOSE: To prevent an elevator car from falling by keeping the elevator car tracking force of each rope uniform by passing one of a pair of ropes round a pair of sheaves and also connecting the tip side of each rope and engaging each rope with the elevator car through a preventive member. CONSTITUTION: An elevator car 1 on which passengers are taken in moves upward and downward by a hoist 13. One end of each of a pair of ropes 9 and 10 is connected to the hoist 13. To the car 1, a pair of sheaves 5 and 6 are attached and a pair of stopper plates 16 and 17 are arranged. In addition, a connecting rod 19, which is engageable with each of stopper plates 16 and 17 is connected to the other side of each of ropes 9 and 10. The other side of each of ropes 9 and 10 is passed around each of sheaves 5 and 6, and the tip side of each of the ropes 9 and 10, and the connecting rod 19 is engaged with each of stopper plates 16 and 17. Through these operations, ropes 9 and 10 can be engaged with the elevator car 1 through the stopper plates 16 and 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home elevator installed in a private house.

[0002]

2. Description of the Related Art As a conventional winding cylinder type home elevator, there is one shown in FIG. 4, for example. In the figure, reference numeral 101 is a car that is vertically movable in a hoistway (not shown), and a car frame 102 is provided on the car 101. Basket frame 102
A guide shoe (not shown) is attached to the guide shoe, and the guide shoe is slidably engaged with guide rails 103 and 104 provided upright on both sides of the car 101.

A pair of ropes 1 is mounted on the car frame 102.
05 and 106 are fixed at one end, and the rope 106 is connected to a pair of overhead sheaves 1 arranged above the hoistway.
08 and 107, the other end of the hoist 109
It is fastened to the drum 109a and wound up. The rope 105 is hooked on the overhead sheave 107, and the other end of the rope 105 is fixed to the drum 109a and wound up.

The hoist 109 is driven to drive the drum 109a.
If the ropes are rotated in the forward and reverse directions, the ropes 105 and 106 will move to the drum 1.
09a is wound up and unwound, and the basket 101
Moves up and down.

[0005]

In such a conventional winding drum type home elevator, when the ropes 105 and 106 for pulling the car 101 are wound around the drum 109a, both ropes are wound evenly. However, one of them may be rolled up in a dumpling shape. Then, the tensions of the ropes 105 and 106 are different, and the forces of pulling the car 101 of the ropes 105 and 106 are different. Therefore, the car 101 is guided by the guide rail 10.
It will be slightly inclined with respect to 3,104. As a result, there is a problem in that the vibration and abnormal noise generated when the car 101 moves up and down becomes large and the riding comfort is not good.

An object of the present invention is to provide a winding-cylinder type home elevator designed to reduce vibration and abnormal noise generated when the car moves up and down.

[0007]

In order to achieve such an object, according to the present invention, a car for carrying passengers and a hoisting machine for vertically moving the car, and a hoisting machine. A pair of ropes whose one end side is connected to the pair of sheaves, a pair of sheaves attached to the car, a blocking member provided on the car, and an engagement that is connected to the other end of the rope and is engageable with the blocking member. A pair of ropes, the other ends of the pair of ropes are respectively hung on the pair of sheaves, the ends of the other ends of the pair of ropes are connected, and when the engaging member engages with the blocking member, The rope is attached to the car through the blocking member.

[0008]

When the hoisting machine is driven to wind up the pair of ropes in order to move the car, one of them may be wound up in a dumpling-like manner. Then, the tension of the pair of ropes will not be the same. However, since the car is placed on the connected ropes through the sheaves, the tension of the pair of ropes becomes the same when the car slightly moves on the ropes. Therefore, the forces of pulling the cars of the pair of ropes become the same, and the cars are vertically moved in a straight state without tilting.

On the other hand, when one of the ropes is broken, the engaging member is pulled by the other rope, and the engaging member is caught by the blocking member and stopped by the blocking member. Then, the other rope is locked to the car and the fall is prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of a home elevator according to the present invention.

In FIGS. 1 and 2, reference numeral 1 is a car that is vertically movable in a hoistway (not shown). A car frame 2 is provided in the car 1, and the car frame is provided. The frame 2 has an upright channel 2a and a plank channel 2b. A guide shoe (not shown) is attached to the upright channel 2a, and the guide shoe is slidably engaged with guide rails 3 and 4 provided upright at both ends of the car 1.

The plank channel 2b is provided with a pair of sheaves 5 and 6 via brackets 7 and 8. The pair of sheaves 5 and 6 are the platform 1a of the car 1.
It is located slightly out of the left and right ends of the. A pair of sheaves 5,
A pair of ropes 9 and 10 are hung on 6 respectively, and the rope 10 is hung on a pair of overhead sheaves 12 and 11 arranged above the hoistway and then drum 13a of the hoisting machine 13. It is fastened to and wound up.
The rope 9 is hung on the overhead sheave 11 and then fixed to the drum 13a and wound up.

As shown in FIG. 3, a pair of thimble rods 14 and 15 are connected to the ends of the ropes 9 and 10 hung on the sheaves 5 and 6, respectively.
Reference numerals 4 and 15 are loosely inserted into the insertion holes 16a and 17a of the stopper plates 16 and 17 (blocking members). Stopper plate 1
6 and 17 are angles 1 installed between brackets 7 and 8.
8 is provided.

The pair of thimble rods 14 and 15 are connected by a connecting rod 19 (engaging member), and the diameter of the connecting rod 19 is larger than the diameter of the insertion holes 16a and 17a. Therefore, even if the connecting rod 19 is pulled by any of the ropes 9 and 10, it is caught (engaged) with one of the stopper plates 16 and 17. Further, compression springs 20 and 21 are interposed between the stopper plates 16 and 17 and the connecting rod 19.
The connecting rod 19 is positioned at the center of the stopper plates 16 and 17 by the urging force of 0 and 21.

In order to move the car 1, when the hoisting machine 13 is driven to wind the ropes 9 and 10 around the drum 13a,
One of the ropes 9 and 10 may be wound around the drum 13a in a dumpling shape. Then, the tensions of the ropes 9 and 10 are not the same.

However, the car 1 is connected to the ropes 9 and 1.
It is placed through sheaves 5 and 6 above 0, so basket 1
By moving a little on the ropes 9 and 10, the tensions of the ropes 9 and 10 become the same. For this reason, ropes 9 and 1
The force of pulling the car 1 of 0 becomes the same, and the car 1 is vertically moved without tilting. As a result, vibration and noise generated between the car 1 and the guide rails 3 and 4 are reduced, and the riding comfort is improved.

On the other hand, if an accident such as a break of the rope 9 occurs during the operation of this home elevator, the connecting rope 19 is pulled by the rope 10. Then, the connecting rod 19 is caught by the stopper plate 17 and is stopped by this. As a result, the rope 10 is locked to the car 1 and this fall is prevented, so that a serious accident can be prevented.

[0018]

As described above, according to the present invention,
Since the other ends of the pair of ropes were hung on the pair of sheaves and the ends of the other ends of the pair of ropes were connected, the forces of pulling the cages of the pair of ropes were the same, and the cages were straight without tilting It is moved up and down in the state. As a result, vibrations and noise generated between the car and the guide rails are reduced, and riding comfort is improved.

When the engaging member engages with the blocking member,
Since the rope is engaged with the car through the blocking member, the car can be prevented from falling and a serious accident can be prevented.
