Description

The present invention relates to a self-supporting telescopic frame system, in particular, an elevator that moves up and down by a constant-speed multistage system, omitting a T-type guide rail fixed in a hoistway.
In particular, the present invention relates to an elevator that moves up and down by incorporating a guide rail mechanism built in a self-supporting telescopic frame instead of omitting the T-type guide rail.

The elevator is usually guided by a T-type guide rail fixed in the hoistway, and is lifted and lowered by a lifting system such as a hydraulic type, a rope type, a linear type or the like.
Recently, indoor open type elevators without hoistways have increased, and how to solve the design problem has become a problem for the people concerned.
Further, the presence of the T-type guide rail has a poor visual effect. In particular, in the case of a hydraulic direct type elevator, the use of glass for the car panel, door, etc. has a problem in appearance because the T-type guide rail is visible.

Furthermore, it is necessary to maintain the same seismic performance as that of a conventional method such as a T-type guide rail, and a solution has been awaited.
Various conventional methods have been proposed and are on the market.
That is, there are a panda graph type hydraulic direct elevator, a heliport type (for disaster and rescue) elevator, a step difference canceller, a home elevator, and the like.

As described above, there are many problems with conventional elevators, and a solution has been awaited.
When solving the problem, it is necessary to maintain the same seismic performance as that of conventional methods such as T-type guide rails. In particular, when the T-type guide rail is removed, there is a problem in terms of seismic performance, and a solution has been awaited. It was.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the conventional technology, and an object of the present invention is to provide a new elevator system that cannot be obtained by the prior art in terms of aesthetic appearance, seismic performance, and safety. is there.

In order to achieve the above-mentioned object, the present inventor has made various studies, and as a result, has a plurality of hollow telescopic frames that are inserted in the longitudinal direction of each other, and a plurality of steps that extend and contract in stages through the inside of the telescopic frame. The telescopic plunger is installed on the underside of the car floor and has sufficient rigidity to withstand the load of the car. Moreover, the telescopic frame has a built-in guide rail function and can be raised and lowered. By being
The present invention has been completed by finding that the T-type guide rail can be omitted and the telescopic frame method is a self-supporting telescopic frame method that can provide an elevator of a telescopic frame method that is strong against disasters such as earthquakes and is safe.

That is, the present invention provides:
(1) A multi-stage hollow telescopic frame that is inserted in the longitudinal direction, specifically, 3 (one-stage frame), 4 (two-stage frame), 5 (three-stage frame), and the telescopic frames 3, 4 5, a multi-stage (hydraulic operation) telescopic plunger that expands and contracts in stages, specifically, 6 (first-stage plunger), 7 (second-stage plunger), 8 (3-stage) Both of which are installed on the lower side of the car floor 2 and have sufficient rigidity to withstand the load of the car 1, and the telescopic frames 3, 4 and 5 are disposed on the inside thereof. This is a telescopic frame type elevator that has a built-in guide rail function and can be raised and lowered.
(2) The shape of the telescopic frame is also characterized in that it includes a multi-stage cylindrical body, specifically, a multi-stage cylindrical shape, a square shape, and a tower shape.
(3) This guide rail function requires a structure comprising a rail and a guide shoe. Specifically, the guide shoe 13 for medium speed, the guide shoe 14 for low speed; the guide rail 15 for medium speed, Like the low-speed guide rail 16 or the like, the present invention is also characterized in that a medium-speed, low-speed guide shoe and a guide rail are incorporated so as to be freely raised and lowered.

(4) The telescopic plunger is also characterized in that it operates by hydraulic pressure. (5) The telescopic frame moves up and down at a constant speed to ensure safety.
(6) It is also characterized in that it is equipped with an automatic control that can stop at a predetermined position when the telescopic frame method is raised or lowered.
(7) The present invention is also characterized in that a rope system or a chain system is used instead of the telescopic plunger system to pull the telescopic frame.
(8) The present invention is also characterized in that positioning devices 23, 23 ', 24, 24', 25 are arranged on door opening / closing ends or the like on the floors of each floor constituting the elevator.
(9) Another feature is that the door driving device 26 is built in the car floor 2.

(A) Since the T-type guide rail is omitted, the observatory elevator using glass is very good in terms of aesthetics.
(B) The door driving device 26 is generally installed on the upper part of the car and opens and closes the door. However, in the system of the present invention, it is more aesthetically pleasing because it is built in the car.
(C) Since a T-type guide rail is not required, an elevator hoistway is not required.
(D) Since the T-type guide rail is omitted, a hardware structure for supporting the rail is unnecessary.

(E) Instead of omitting the T-type guide rail, a telescopic frame system that is resistant to earthquakes was adopted.
(F) Safety is ensured by raising and lowering the motion of the telescopic frame, that is, 3 (1 step frame), 4 (2 step frame), and 5 (3 step frame) at a constant speed.
(G) A guide rail function, that is, guide rails 15 (for medium speed) and 16 (for low speed); guide shoes 13 (for medium speed) and 14 (for low speed) are incorporated into the telescopic frame system, so There was little shaking and the seismic performance equivalent to the conventional method was secured.

(H) Since the seismic load is basically received in the pit via a self-supporting frame, an excessive load is not applied to the building on the ground.
(Li) The depth of the elevator pit can be reduced by the telescopic frame method.
(Nu) Positioning devices 23, 23 ', 24, 24', 25 are arranged on the door opening / closing ends so that the doors can be opened and closed smoothly on each floor floor, so that some misalignment can be absorbed.

The telescopic type referred to in the present invention is an industry term and means a multistage type.
In addition, the "automatic control that can stop at a predetermined position" when raising and lowering the telescopic frame method of the present invention means that when a car jumps or shakes in an elevator car, the car is automatically detected to be safe. Therefore, the elevator is in the seismic control mode, landing on the lower floor, and then the control function to stop.
The frame used in the telescopic frame system of the present invention includes a cylindrical body, specifically, a multistage cylindrical shape, a square shape, and a tower shape.

The present invention will be described below with reference to the drawings.
