[0020]

The operation and operation of the present invention will be described.
When the tare weight of the lift 2 is set to about 50 kg, the weight of the counterweight 3 is set to, for example, 150 kg. In this way, the counterweight 3
The lifting platform 2 is lifted up via the suspension ropes 4 and 4 by the weight of the counterweight 3 as a driving source, so that the lifting platform 2 can be freely used. Therefore, when the elevator 2 is stopped at the level of the floor C on the first floor as shown in FIG. 1, the towing rope 7 is forcibly wound up by the towing actuator 6 provided on the base 9, whereby the elevator Since the weight of the counterweight 3 is balanced with the weight of the counterweight 3 by the traction force of the traction rope 7 to the weight of the lift 2, the elevator 2 stops at the fixed position. This stop position is controlled by the positioning switches 21 and 21 of the counterweight 3. Then, when the stop button on any of the operation panels 25, 26 is operated, the electromagnetic brakes 19, 19 are actuated, and the elevator 2 is fixed to the column 1, so that a reliable stop state is achieved.

In this state, if a person gets on the lift 2 and operates the lift button on the operation panel 27, the electromagnetic brakes 19 and 19 are turned off by a signal from the controller 24, and the brake of the actuator 6 is not released or released. The tow rope 7 is weakened and can be extended, whereby the counterweight 3 descends as long as the sum of the weight of the elevator 2 and the weight of the personnel is smaller than the weight of the counterweight 3. As a result, the lift 2 connected to the counterweight 3 by the suspension ropes 4 and 4 rises as the counterweight 3 descends. The moving speed of the lift 2 can be freely set by controlling the brake strength of the actuator 6.

When the elevator 2 reaches the predetermined ascending position, the positioning switches 21 and 21 are actuated, whereby the brake of the actuator 6 is actuated and the pulling out of the tow rope 7 is stopped and the state is maintained. Therefore, as shown in FIG. 2, the elevator 2 stops at the level of the floor D on the second floor, and when the stop button is pressed, the electromagnetic brakes 19 and 19 are activated to secure the elevator 2 to the column 1. You can get off safely.

When the operation panel 26 is operated downward in this state, the actuator 6 is operated and the tow rope 7 is wound up, so that the elevator 2 is towed against the weight of the counterweight 3 and thereby the ascending and descending is performed. The platform 2 descends. This descent speed can be arbitrarily adjusted by controlling the rotation speed of the actuator 6. When the stop position is reached, the positioning switches 21 and 21 are operated, whereby the operation of the actuator 6 is stopped, and the tow rope 7 is maintained in that state. As shown in FIG. Stop at floor C level. When the stop button is pressed, the electromagnetic brakes 19 are operated, so that the lift table 2 is reliably kept stopped.

The elevating platform 2 is held so as not to be separated from the column 1 by slide cylinders 10, 10 and connecting fittings 11, 12, and the elevating platform 2 has guide cylinders 16, 16 at the back.
Is slidably fitted to the steady rest members 17, 17 connecting the upper plate 8 and the base plate 9, and therefore does not swing in the left-right direction. Therefore, the elevator 2 is always in a stable posture with the support 1 as a guide. It can move smoothly.

When a part of the human body, clothes, or belongings protrude from the floor of the elevating platform 2 during the above movement, the strip 150 provided in the opening is provided.
When the emergency stop switch 15 is contacted, the emergency stop switch 15 is operated, and the electromagnetic brakes 19, 19 are automatically operated by the signal from the controller 24 to stop and lock the elevator 2 urgently, so that safety can be secured. When the protrusion has disappeared, if the up or down button is pressed, the actuator 6 is restarted and the electromagnetic brakes 19 and 19 are turned off.

When two or more persons weighing more than 50 kg are on the first or second floor and the weight including the lift 2 exceeds the weight of the counterweight 3, the lift 2
Is unable to ascend and falls naturally. As a result, the tension of the tow rope 7 which has been in a tension state is lost. When the emergency switch 20 detects this and sends a signal to the controller 24, the electromagnetic brakes 19 and 19 are automatically operated, the elevator 2 is emergency stopped, and the descent is locked, which is safe. Then, the actuator 6 is driven and driven until the tow rope 7 is tensioned, and waits for recovery.

Although the safety is ensured by the above, if the elevator 2 falls naturally due to the loose connection of the hanging ropes 4, 4 and the counterweight 3, the lower surface of the floor plate 2a of the elevator 2 is The provided buffer plate 18
Abuts against the shock absorbers 13 of the base plate 9, the impact is absorbed and safety can be achieved.

The column 1 has a counterweight 3 and a lift 2
Since it is a strength member that supports the load of the vehicle and the weight of the occupant, it also serves as an elevating guide of the elevating platform 2, so that the safety can be enhanced while having a simple structure. First
When the number of the columns 1 is one as in the embodiment, the number of members used including the electromagnetic brakes 19 and 19 is small, and the present invention can be applied not only to new construction but also to remodeling and reforming. Further, in the present invention, the lifting power source of the lift 2 is the counterweight 3, the own weight (or the weight of the occupant) of the lift 2 is used as the lower power source of the lift 2, and the actuator 6 is insufficient. It is enough if there is output to make up for the minute. Therefore, the actuator 6 can be made to have a relatively small capacity, and the size can also be reduced. In the present invention, since each component is light in weight and can be easily disassembled, it can be easily transported and carried in, so that it can be installed relatively easily in an existing house as well as in a new building.

[0029]

According to the present invention described above, the column 1 is erected on the base 9 fixed on the foundation of the building, and the elevator 2 is slidably mounted along the column 1, 1
An upper bracket 8 having pulleys 5 and 5 is provided at the upper part of the counter, and one end of the hanging ropes 4 and 4 mounted on the pulleys 4 and 4 is attached to the lift 2 and the other end is a counter having a heavier weight than the lift 2. Connected to the weight 3 respectively,
Is connected to a tow rope 7, and the base 9 is provided with an actuator 6 for rewinding or feeding out the tow rope 7, so that it is possible to safely move to each floor in a multistory house with a simple structure. Moreover, the counterweight 3 is used as a power source for ascending, and the total weight of the elevator 2 and the occupant is used as a power source for descending.
Since the output of the power source for compensating for the shortage of the power of the descending power source is sufficient, the size of the power source can be reduced. According to the second aspect, an excellent effect that the safety can be enhanced can be obtained. According to the third aspect, an excellent effect that simple and low cost can be obtained is obtained. According to the fourth aspect, when a load exceeding the weight of the counterweight 3 is applied to the lift 2, an excellent effect is obtained in that the load can be automatically detected and the lowering of the lift 2 can be stopped. Can be
