Abstract

PURPOSE:To make a mast member in a small size and a unit and also ease the carrying-in of a member and installation in an existing house by mounting a detachable cage on an elevating plate of a telescopic multistage mast device. CONSTITUTION:A cage 4 elevating in an elevation tube is detachably mounted on an elevating plate 3, and the elevating plate 3 is elevating-freely engaged with a telescopic multi-stage mast device 2. Moreover a guide rail 7 is provided on a wall surface facing the multi-stage mast device 2, and the cage 4 is made elevating possible along the guide rail 7. Because thus the rod 27 of the hydraulic cylinder 26 of the mast device 2 is extended at the time of the cage 4's rising and the cage 4 can be naturally lowered by the action of gravity when lowered, construction is eased with a house's column unreceiving a load, and member carrying and elevator installation can be eased with a mast member realized a small size and a unit.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a home elevator for use in a single private residence.

[Conventional technology]

Conventional home elevators have the following configuration as lift means for raising and lowering the car.

In other words, there are two types: an electric method in which the car is moved up and down by winding or unwinding a rope with a single hoist, and a hydraulic method in which the car is moved up and down by the telescoping motion of a hydraulic jack. There is a direct method in which the car is pushed up by a hydraulic jack, and an indirect method in which a rope is interposed between the car and the hydraulic jack and the car is raised and lowered in a stroke twice as long as the stroke of the hydraulic jack.Moreover, the car is moved up and down along a lift member made of a single member. It was configured as follows.

[Problems to be Solved by the Invention] Conventionally, the above-mentioned lift member has a structure in which a set of single members is erected, and therefore there are the following problems.

■ The lift member was long and difficult to transport.

■ Because it was a collection of single parts, there were many connections on site, which required a lot of time to construct.

■ Because long objects were being brought in and installed, the construction period for the elevator was dependent on the construction status of the house.

[Means to solve the problem]

First of all, the present invention has a structure in which a car that moves up and down in a hoistway is detachably attached to a lift plate, and the lift plate is engaged with an extendable multi-stage mast device so as to be able to move up and down. There is also a second type that has a structure in which a guide rail is provided on the surface facing the mast device, and the car is moved up and down along the guide rail.

[Effect]

To explain the operation of the present invention, first, when raising the car, when the lot of the hydraulic cylinder is extended, the car is raised. When descending, the car naturally descends due to the action of 3 gravity (9 Although not shown in the figure, for safety reasons, when descending, a throttle valve is inserted and connected to the hydraulic pipe to throttle the oil discharged from the hydraulic cylinder. (It is also equipped with a safety valve that locks the hydraulic cylinder in case the hydraulic line ruptures.)

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 and 3. l is a hoistway, 2 is a multi-stage mast device, 2
1.21 is a fixed mast member that stands perpendicularly to the ground or floor surface. 22.22 is the fixed mast member 21.
21, an elevating mast member that freely moves up and down along it; 23, a connecting member that connects the lower part of the fixed mast 1 member 21.21; 24, a connecting member that connects the upper part of the fixed mast member 21.21; 25; 22 is a member connecting the upper part of the lifting mast 22.22, and 26 is the fixed mast member 21.2.
1, 27 is the lot of the hydraulic cylinder 26, and 28 is rotatably attached to the member 25 connecting the upper part of the lifting mass 1, 22, and 22 via a bracket 29. Cembo eel 3 is an elevating plate that freely moves up and down within the elevating mass 22, 22, and one end of a ceno (or a rope may be used) 30 related to the ceno wheel 28 is fixed. The other end is hydraulic cylinder 2
It is fixed to the bottom side 31 of 6.

Reference numeral 4 denotes a basket, which is freely attached to the elevating plate 3 with bolts or the like. Reference numeral 5 denotes a hydraulic drive device in which a motor 51 is rotationally driven by an on signal from an operation switch (not shown).
The hydraulic pump 52 is operated and pressure oil is supplied to the bottom side 31 of the hydraulic cylinder through the pipe 53, and the rod [27] is extended. When the rod 27 is extended, the lifting mast 22.2
A member 25 connecting the upper parts of the two wheels is rotatably attached to the member 25 via a bracket 29.
At the same time as the lifting mast 22.22 starts to rise, the lifting plate 3 to which one end of the chino 30 is fixed rises at twice the speed of the lifting mast 22.22.

That is, the car 4 rises (see especially FIG. 3).

6 is a cushion member arranged on the ground or floor surface,
To reduce shock when the car 4 is lowered.

In FIG. 2, a guide rail 7 is provided in addition to the one shown in FIG. 1, to make the lifting and lowering operations smoother.

〔effect〕

The present invention has the following effects by adopting the above-described configuration.

■ Since the load of the car is received only by the multi-stage mast device,
The pillars of the house do not bear any load. Therefore, there is no need to consider strength distribution from the beginning of the design.

It is easy to install even in existing houses.

■ It consists of a fixed mast member and an elevating mast member, and since the elevating mast member can be stored inside the fixed mast member, it can be made smaller and unitized, making it easier to transport and allowing it to be installed regardless of the construction period of the house. I can do it.

■ The basket and mast device are removable.

It has the advantage of being easy to transport and being able to be carried out separately.

■ Due to the characteristics of ■ and ■, it has a great practical effect in that it can be installed even if the structure of the building is a steel frame structure, a reinforced concrete house, or a wooden house.
