Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to domestic elevators, and more particularly to elevators installed in two-story wooden houses.

Conventional technology and its problems Conventional elevators require an elevator shaft that is specially installed in the building to raise and lower the elevator car.
It is equipped with a drive winch that is installed above the upper end of the elevator shaft, and it is relatively easy to install in buildings with steel or reinforced concrete structures and is satisfactory in use. . However, conventional elevators are structurally and economically unsuitable for general household use, especially for the two-story wooden houses that make up the overwhelming majority of elevators in Japan.

Therefore, it is extremely rare to see a conventional elevator with a cage-driving winch installed at a high place installed in a Japanese-style house.

On the other hand, as the population ages, the number of people who feel uncomfortable going up and down stairs is increasing. For this reason, there is a desire for an inexpensive and safe elevator that can be easily installed in wooden houses.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a domestic elevator that does not require a driving winch placed above an elevator passageway and can be installed simply, inexpensively, and safely in a two-story wooden house.

The above object of the present invention is to provide a frame body which is attached to a part of a building and is provided with a pair of supports that are separated at a predetermined interval and reach from the floor level of the first floor to the ceiling level of the second floor. a box-shaped cage guided by moving wheels; a screw punch of a predetermined length attached to the frame and extending downward from the upper end of the frame;
a female screw member that is attached to the upper end of the cage via a support member and is screwed into the screw screw; and a female screw member that is connected to the female screw member when the screw punch is fixed to the frame body; When the members are fixed to the cage, this is achieved by the domestic elevator of the present invention, which is comprised of a rotating drive source such as an electric motor connected to a screw punch.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the apparatus of the present invention will be described below with reference to an embodiment shown in the accompanying drawings.

Referring to the drawing, it is installed on a part of the building and is
An elevator 30 according to the invention is shown comprising a frame 5 with a pair of supports 4α, 4b reaching the floor ceiling level and a cage 1 placed on the left side of the frame 5. A pair of support columns 4α, 4A are separated at a predetermined interval S and are vertically and rigidly assembled by horizontal beam members 5a to form a frame 5. Posts 4α, 4b
The lower end is fixed vertically to the floorboard of the first floor or it is attached to a vertical foundation buried in the ground, and the approximately center part of the height is fixed to the floor of the second floor to support the weight of the occupants and cage 10. do. The pillars 4α, 4b are provided with a guide rail 4G mounted in parallel on the left side.

The cage 1 has an entrance for the occupants on the left side, and a door 2 is attached thereto. The cage 1 has a support arm 13Z protruding to the right from the side wall opposite to the entrance. Each support arm 13a, 13b is provided with a guide roller 14 at its right end that rolls along a guide rail 4G.

A screw punch 6 having a predetermined length is attached to a metal fitting 15 at the center of the upper end of the frame 5.
It is attached through a holder and its lower end hangs vertically. In the illustrated example, the screw punch 6 is fixed to the frame 5, but it can also be attached to the frame 5 so that it can rotate freely.

The cage 1 is provided with a support member 8 consisting of a substantially horizontal planket extending from the upper end toward the frame body 5, and a female screw member 7 screwed into the screw punch 6 is rotatably mounted on the support member 8.・It is being done. The female screw member 7 has a pulley 9 fixed to its lower end. A belt-driven pulley 11 with a vertical electric motor 12 attached to the output shaft attached to the upper surface of the top plate of the cage 1
It is equipped with An endless bell (10) is hung between the pulley 9 and the belt-driven pulley 11.

Therefore, by rotating the female screw member 7 by operating the electric motor 12, the cage 1 can be raised and lowered.

As mentioned above, in the modified embodiment in which the screw punch 6 is rotatably attached to the frame 5, a pulley (not shown) fixed to the screw punch 6 is connected to the belt drive pulley 11 on the drive motor side via an endless belt. Then, the female thread member 7 is fixed to the cage top plate. ,.

A pair of cantilever-shaped plunkets 21 are provided on the left side of the upper end of the frame 5.
α, 21h are attached, and a horizontal rotating shaft 20 is supported at both ends by the plumkets 21α, 21b.

The rotating shaft 20 has pulleys 18α, is, and 6 attached to both ends. Wires 17α and 17b are connected to pulleys 18α and 1, respectively.
It is hung on 8b. The left ends of the wires 17α, 17b are connected to hanging points 19α, 19h at the upper end of the cage 1, and the right ends are fixed to the counterweight 16, respectively.

The feature of the present invention is that the entire weight of the elevator is supported by the frame, and the frame is supported on the first floor floor (if the floor is insufficiently strong, it is reinforced as appropriate), but the frame is subject to uneven loads. In order to resist the bending moment, the frame is fixed to the floor of the second floor, and the upper end of the frame is fixed to the floor of the second floor. The purpose is to obtain stability by utilizing and fixing.

In addition, unlike conventional elevators, the cage is not suspended by wires, but is suspended from the screws via female screw members, so the safety factor can be improved several times compared to wires, and it is a safety device against falling. It has the advantage of not requiring

Since the elevator 30 of the present invention has a weight of about 200-300, it can be installed very easily in a newly built house, and there will be no difficulty in installing it in an existing house. In consideration of natural disasters such as earthquakes, it is sufficient to appropriately strengthen the mounting of the frame 5 and the supporting portions.

The cage lifting mechanism comprising the screw punch 6 and female screw member 7 of the present invention is simple and reliable, and does not require a winch room projecting upward from the roof of the house, making it ideal for Japanese-style two-story houses. it is conceivable that.

As shown in the figure, since the screw punch 6 is fixed to the frame body 5 at the upper end, the screw punch 6
Since only tensile stress is applied to , and no compressive stress is applied, there is no possibility that buckling of the screw punch 6 will occur. Base 6
The diameter of the wire is several steps larger than the diameter of the wire used in normal elevators, so it is not as safe as previous elevators. The female screw member 7 screwed into the screw punch 6 prevents vibration of the screw punch 6 and helps stabilize the attachment of the screw punch 6.

Effects of the Invention The effects of the present invention are that the screw punch 6 is used as the elevating drive mechanism.
This eliminates the need for a shaft and a drive winch installed at the upper end of the shaft, thereby simplifying the overall structure and greatly reducing manufacturing costs.

Another advantage of the present invention is that it avoids applying compressive stress to the screw punch 6 and can be used without buckling, thereby improving its service life.
