Description

[Detailed description of the invention] <Industrial application field> This invention relates to a lift for houses.
In particular, it can be used as a simple lift that is convenient for small-scale warehouses, two-story barns of farmers, or general households.

<Prior art> In conventional lifts installed in houses, a guide frame is installed in the space where the lift moves up and down, and a box-shaped or plate-shaped lifting body is moved up and down within the installed guide frame using lifting means. ing.

Therefore, a guide frame is provided between the first floor and the second floor where the lift goes up and down, and this space is partitioned off as an exclusive area for the lift, so it cannot be used for other purposes and is subject to space limitations. .

If the lift is installed in a large space and the lift needs to be used frequently, it is possible to use a conventional lift, but this is uneconomical in a house where there is not enough space and the lift is used infrequently.

Therefore, the present invention aims to make effective use of space by providing a simple lift.

<Means for Solving the Problems> In the present invention, an elevating frame 3 that is suspended by an elevating means 5 and that moves up and down is inserted into a guide frame 1 that is vertically fixed only to the upper part of the floor 4, and this elevating frame A horizontal stand 10 is attached to the lower end of the elevator frame 3, and the horizontal stand 10 normally closes the cutout hole 13 drilled in the floor 14 of the upper part 4, forms a part of the floor, and
The upper floor 14 and the lower floor 15
It is designed to move up and down between the floor 16 and the floor 16.

<<Function>> In the lift of the present invention, the lifting frame 3 of the lift is inserted into the guide frame 1 when not in use, and the horizontal platform 10 on which objects to be transported attached to the lower end of the lifting frame 3 is placed is placed on the floor 14 at the upper floor. Since the lift forms part of the lower floor 15, there is no space occupied by the lift and it can be used freely.

In addition, a cutout hole 13 is cut out in the floor 14 of the upper floor 4 so that the lifting part of the lift can pass through.
Since the horizontal platform 10 at the lower end of the lifting frame 3 is closed,
There is no risk of people or objects falling, and the horizontal platform 10 can also be used as the floor 14 of the upper floor 4.

By raising and lowering the lifting frame 3 using the lifting means 5, the object can be placed on the horizontal platform 10 and transported by moving up and down between the floor 14 in the upper part 4 and the floor 16 in the lower part 15, The elevating frame 3 moves up and down while being guided by the guide frame 1, and since the guide frame 1 is fixed vertically, the elevating frame 3 also moves up and down while being guided in the vertical direction.

<<Embodiment>> The drawing shows an embodiment of the present invention, and the lift includes a guide frame 1, an intermediate frame 2 inserted into the guide frame 1, an elevator frame 3 inserted into the intermediate frame 2, and a guide frame 1.
It consists of a lifting means 5 attached to the upper end of the floor and fixed to the ceiling of the upper floor 4.

The guide frame 1 has a lifting means 5 whose upper end is fixed to the ceiling.
It hangs down from the case and is located only on the upper floor 4.

A roller 6a pivoted to the front of the upper end of the intermediate frame inserted into the guide frame 1 is inscribed in the front folding surface of the guide frame 1, and a roller 7a pivoted to the back surface of the guide frame 1 is attached to the intermediate frame 2. It comes into contact with the back surface, smoothing the rise and fall of the intermediate frame 2, and ensuring support.

Similarly, the lifting frame 3 has a roller 6b whose upper part is pivoted to the front, and a roller 7 whose lower part is pivoted to the back of the intermediate frame 2.
The tip of a wire 16 of a hoist 9 of the elevating means 5 is tied to an upper connecting member 8 which is inserted into the intermediate frame 2 and connects the left and right frame plates.

The hoisting machine 9 is driven by a forward and reverse rotation motor with a brake, and moves the lifting frame 3 up and down, as well as suspending and supporting it.

At the lower end of the lifting frame 3 is a horizontal platform 1 on which objects to be transported are placed.
0 is attached, and the intermediate frame 2 is inserted into the guide frame 1 in a free state, but it is supported by the lower end coming into contact with the horizontal table 10, and as the lifting frame 2 moves up and down, the floor 14 of the upper floor 4 and the floor 16 of the lower part 15.

11a and 11b are stopper pieces installed on the upper back surfaces of the intermediate frame 2 and the lifting frame 3; 12a and 12b are stopper receiving pieces installed on the lower back sides of the guide frame 1 and the intermediate frame 2; limits the descent of

Reference numeral 13 denotes a cutout hole drilled in the floor 14 of the upper floor 4, and has a shape and width through which the intermediate frame 2, the lifting frame 3, and the horizontal platform 10 can pass through, and when the lifting frame 3 is located at the upper floor 4. In this case, the horizontal platform 10 is flush with the floor 14 of the upper part 4 and closes the cutout hole 13 to form a part of the floor.

The embodiment in the drawings has an intermediate frame 2 and a lifting frame 3.
Although the lifting frame 3 can be inserted directly into the guide frame 1, the lifting frame 3 can be inserted directly into the guide frame 1, and if there are a plurality of intermediate frames 2, the lifting frame can be The stability of 3 increases.

<<Effect of the invention>> As described above, the present invention does not require the installation of a guide frame etc. in the lower floor 15 for raising and lowering the lift, so if the lift is raised to the upper floor 4 when not in use, the lower floor can be used without restrictions. There are effects that can be used.

Also, in the upper part 4 of the floor, the cutout hole 13 made in the floor 14 for raising and lowering is closed by the horizontal platform 10 of the elevator frame 3, so there is no danger, and this horizontal platform 1
0 can be used as part of the floor 14, and even in the upper part 4 of the floor, space can be used effectively with minimal restrictions.

Since the elevating frame 3 is inserted into the guide frame 1 which is fixedly suspended from the upper part of the floor 4, the elevating and lowering of the elevating frame 3 is regulated by the guide frame 1, which has the effect of reliably moving in the vertical direction.
