DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator that can be used as a so-called home elevator or a construction elevator in a general house.

[0002]

2. Description of the Related Art Referring to FIG. 2. Description of the Related Art Conventionally, elevators used in general houses and the like have a complicated structure and are large-scale, and therefore require a large installation space and are expensive.

[0003] That is, this conventional elevator is equipped with a car 20
Guide rails 21 are provided on both left and right sides of the vehicle, and a plurality of columns 22 for supporting the guide rails 21 are provided. Further, since the rollers 23 for rolling the guide rails 21 are of a flat type, three or more rollers 23 are provided at one location in order to maintain the front, rear, left and right forces. Further, a plurality of gear rack rails 24 are provided separately from the guide rails 21. In order to further support the balance weight 25, a column 2
2, including a strong and complex steel tower structure.

[0004]

Problems to be Solved by the Invention Elevators conventionally used for ordinary houses and construction work have complicated and large structures, require a large installation space, and are expensive. An object of the present invention is to solve such a problem.

[0005]

A description will be given with reference to FIGS. The elevator of the present invention is an elevator that can be used as a shared load for general housing and construction,
A guide guide rail 2 having one side surface as a first angled portion 2a is provided along one side of the front surface of one vertically-supported column 1 and one side surface along the other side of the front surface of the column 1 Is a second angled portion 3a, and a drive guide rail 3 provided with a rack 3b on the other side is attached.
The center of the back of the car 4 on which the cargo is to be placed is opposed to the car 4, and a gear 7 which is rotated by a motor 5 and meshes with the rack 3b of the drive guide rail 3 is rotatably mounted on the back of the car 4; First mountain section 2 of guide guide rail 2
The first roller 8 rolls when the first valley portion 8a comes into contact with a
And a second roller 9 that rolls when the second valley-shaped portion 9a comes into contact with the second mountain-shaped portion 3a of the drive guide rail 3, and a distal end portion of the wire 10 fixed to the ceiling wall of the car 4. Is fixed to the balance weight 12 in the support column 1.

[0006]

2 to 4 show an embodiment of an elevator according to the present invention. The elevator is capable of carrying both people and luggage as a so-called home elevator for a general house or an elevator for construction.

[0007] In the elevator, a guide guide rail 2 having a first angled portion 2a on the outer side is vertically moved along a right side of the front surface of a single column 1 having a flat rectangular shape which is erected vertically. Two are provided. In the vertical direction along the left side of the front surface of the column 1, two drive guide rails 3 each having an outer side surface as a second mountain-shaped portion 3a and a rack 3b provided on an inner side surface are similarly mounted in the vertical direction.

Then, the center of the back of the car 4 on which the load is to be placed is opposed to the front of the column 1, and the car 4 is rotated by a motor (servo motor) 5 on the back of the car 4.
A gear 7 meshing with the rack 3b of the drive guide rail 3 is rotatably mounted together with the motor 5. Further, a speed reducer 6 is also attached, and the rotation of the motor 5 is reduced.

On the back side of the car 4, a first roller 8 is provided which rolls when the first valley 8a comes into contact with the first ridge 2a of the guide rail 2. In addition, a second roller 9 is provided on the rear surface of the drive guide rail 3 so that the second roller 9 rolls when the second valley portion 9a comes into contact with the second mountain portion 3a. And the wire 1 fixed to the ceiling wall of the basket 4
The distal end of the cage 0 is fixed to a balance weight 12 for balancing the weight of the car 4 in the space within the support column 1. In addition, a pulley 11 for receiving the wire 10 is provided at an upper end portion of the column 1 to make the movement of the wire 10 smooth.

The operation of the elevator according to this embodiment will be described. To raise or lower the elevator, the switch is turned on and the motor 5 is rotated. The rotation of the motor 5 is reduced to a certain level by the speed reducer 6 and transmitted to the gear 7.
When the gear 7 rotates, the gear 7 meshes with the rack 3b, and thus moves up or down along the rack 3b. Thereby, the car 4 to which the gear 7 is attached moves up or down.

At this time, the first roller 8 attached to the car 4
The first valley-shaped portion 8a of the second roller 9 comes into contact with the first valley-shaped portion 2a of the guide guide rail 2 attached to the column 1 and rolls. , And rolls in contact with the second chevron 3a, so that the car 4 can maintain a stable posture.

Here, the first valley section 8a and the second valley section 9
a, the first chevron part 2a and the second chevron part 3a are all formed on the side face outward or inward. Movement is prevented beforehand, and the attitude of the car 4 is kept stable. In addition, the posture of the car 4 in the left-right direction is similarly kept stable by these members.

Since the weight of the car 4 is balanced by providing the balance weight 12, the car 4 can be smoothly moved up and down. Since the balance weight is arranged in the column 1, it does not take up any space, so that the installation place of the elevator can be reduced.

In this elevator, the car 4 can be moved up and down in a stable posture with one pillar 1 as an axis, so that a conventional steel tower consisting of a plurality of pillars is not required.
The structure is simple. Therefore, the installation location can be reduced and the price can be reduced.

[0015]

The elevator according to the present invention has one support 1
, The car 4 can be moved up and down in a stable posture. Therefore, the structure is simple, a large installation space is not required, and the manufacturing and provision prices can be suppressed.

In addition, since one support is made independent by one support,
It is not affected by the structure of buildings such as houses. Therefore, the degree of freedom in designing a building is increased, and the building can be installed in an existing building. At the same time, a free design is possible, such as making the shape of the car 4 circular.
