Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic elevator for a low house, which is used as a low house on the fourth floor or below and a home for the elderly, and as a lift for a construction site.

[0002]

2. Description of the Related Art In a conventional elevator, a wire connected to an elevator box is passed through a winding device provided on a ceiling of a frame body to attach a weight, and the wire is wound by the winding device. It was operated by moving it back and forth.

Further, in an indirect hydraulic elevator, a pulley and a hydraulic cylinder are combined to function.

[0004]

In the conventional elevator, since the winding device is installed on the ceiling of the frame structure, it is necessary to make the structure of the frame structure strong, which is a great problem for the installation work. It was time consuming and expensive.

In view of the above points, an object of the present invention is to install a hydraulic cylinder lifting type elevator box in a unitized frame body to simplify the work and provide it at a low cost.

[0006]

As shown in the figure, the means for solving the problems according to the present invention is to fix a foundation base 1, a vertical pillar 2a vertically built in a square of the foundation base 1, and a vertical pillar 2a. For supporting the horizontal pillar 2b and the diagonal member 2c, the convex rails 3a and 3b attached to the central portions of the right and left side surfaces in the frame 2, and the convex rails 3a and 3b. And an elevator box 4 that moves up and down, a hydraulic cylinder 5 that is connected to an upper part of the box 4 to move the elevator box 4 up and down, and is installed upright on the foundation base 1 and attached to a side surface of the elevator box 4. The protrusions 3c, 3 of the convex rails 3a, 3b
and a holding device 6 for holding d by a roll.

[0007]

In the above means for solving the problems, the hydraulic cylinder 5 pivotally connected to the upper rear portion of the elevator box 4 is connected.
In addition, when the hydraulic pressure is applied through the motor 7 and the pump 8 only during the extension, the elevator box 4 rises along the convex rails 3a and 3b.

Also, the door 10 of the elevator box 4
The opening and closing configuration of the elevator box 4 will be described with reference to FIG. 3. The projecting metal fittings 11 provided at the door end of the elevator box 4 enter the planar view C-shaped insertion metal fittings 13 attached to the floor doors 12 from below or above. When 4 stops at each floor, the door 12 at the entrance to each floor opens together with the door 10 of the elevator box 4 (a known opening / closing mechanism is appropriately used).

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below. In the illustrated hydraulic elevator for a low house, a foundation base 1, vertical columns 2a vertically installed in the squares of the foundation platform 1, and vertical columns 2a.
A frame 2 composed of a horizontal pillar 2b and a diagonal member 2c for fixing the rails, convex rails 3a, 3b attached to the central portions of the right and left side surfaces in the frame 2, and the convex rails 3a,
It is composed of an elevator box 4 which is guided by 3b to move up and down, and a hydraulic cylinder 5 which is connected to the upper part of the box 4 to move the elevator box 4 up and down and which is erected on the foundation 1 to stand upright.

The elevator mechanism for the elevator box 4 will be described. As shown in FIG. 2, the convex rails 3a, 3b mounted on the side surface of the elevator box 4 at the center of the left and right side surfaces in the frame assembly 2 are described. Loosen the protrusions 3c and 3d.
The holding device 6 is attached to the elevator box 4. The device 6 includes a roll fixing arm 6a attached to a total of four places on the left, right, upper and lower parts of the elevator box 4, and three rolls 6b axially supported by these rolls. It is composed of 6c and 6d.

Further, hydraulic pressure is applied to the hydraulic cylinder 5 pivotally connected to the upper rear portion of the elevator box 4 through the motor 7 and the pump 8 only when the hydraulic cylinder 5 extends.
Further, when the valve is released, it is configured to be shortened by the weight of the box 4, so that the elevator box 4 moves up and down along the convex rails 3a and 3b.
When the holding device 6 is attached to the elevator box 4, a shock absorber (rubber material) 9 is used to prevent vibration and noise.
Is intervening.

Also, the door 10 of the elevator box 4
The opening and closing configuration of the elevator box 4 will be described with reference to FIG. 3. The projecting metal fittings 11 provided at the door end of the elevator box 4 enter the planar view C-shaped insertion metal fittings 13 attached to the floor doors 12 from below or above. When 4 stops at each floor, the electromagnetic lock 14 is released by the detection of the sensor, and the door 12 at the entrance of each floor is opened together with the door 10 of the elevator box 4 (a well-known opening / closing mechanism is appropriately used). is there. Elevator box 4
In order to close the door, the electromagnetic lock 14 is applied to each floor door 12 in the reverse order of the above, and the protruding metal fitting 11 is placed below the plan view C-shaped insertion metal fitting 13 in a state in which it is prevented from falling. It comes off in the upward direction, and the box 4 starts moving up and down.
Thus, by equipping each floor door 12 with the electromagnetic lock 14 so as to be associated with the door 10 of the elevator box 4, it is possible to enhance safety for the elderly and children.

The foundation base 1 of the framework 2 may be constructed on site, the framework 2 may be assembled in the factory to some extent, or the entire assembly 2 may be installed at once using a crane or the like. It is possible. In this way, the foundation base 1 is first made solid, and on top of that,
The left and right convex rails 3a and 3b in the frame body 2 connected by the studs are held by the four holding devices 6 mounted above and below the left and right outer side surfaces of the elevator box 4, and the elevator box 4 Is guided up and down.
Moreover, due to the structure in which the hydraulic cylinder 5 pushes up the upper rear portion of the elevator box 4 from directly below, it is supposed to be able to withstand vibration such as an earthquake.

The perspective view shown in FIG. 1 shows the internal structure. Usually, the outside is surrounded by a fireproof outer wall 15 to prepare for a fire.

Furthermore, the hydraulic elevator for a low house of the present invention can be incorporated inside a house,
As shown in FIG. 4, it is also possible to install it next to an already built house and connect each floor. It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

[0016]

As is apparent from the above description, the structure of the conventional elevator is required to have high strength because the ceiling of the framework is heavy, but in the present invention, the central parts of the left and right side surfaces in the framework are required. The weight of the elevator box, which is moved up and down by being guided by the convex rails attached to the base, is applied to the foundation base via a hydraulic cylinder that is connected to the upper part of the box and is erected on the foundation base. Because of the structure, it is possible to make the foundation foundation solid and to keep the upper framework relatively lightweight. That is,
The structure is relatively simple and can be completed in 3-4 days. Further, there is an excellent effect that the cost can be reduced to about 1/5 as compared with the conventional structure.
