Description

  The present invention relates to an elevator that can go out of a room such as a house as it is by itself.

  A conventional elevator includes a combination of an elevator and a slope (see, for example, Patent Document 1).

The conventional elevator will be described. It is an elevator having a structure in which a manually operated elevator that moves up and down vertically and a slope bridge that can change the angle according to the height of the elevator.
JP 2002-161571 A

  The conventional elevator described above is a dedicated elevator for a manual toilet for a wheelchair user, but can be diverted to the side of the stairs on the porch of a house. However, to enter the room, one unit is also required at the level difference (average height of about 25 cm) from the hallway in the entrance, but it seems that the entrance cannot be installed in space. It is also possible to install it directly into the room, but in that case, a site space equivalent to building a slope with concrete or mortar is required.

  The present invention is intended to solve the problems of such a conventional configuration, and a wheelchair user can easily go out by himself / herself in a site space of 50% or less when a slope is made. It aims at realization.

  In order to achieve the above object, the present invention is an electric elevator of a mechanical system that applies the laws of a parallelepiped and a parallelogram, and allows the user to go out by himself with a wheelchair from inside the house.

  If this law is explained with reference to FIG. 3, the surface 1 is a lifting floor on which a wheelchair is placed, the surface 2 is the ground surface, the surface 3 is between AC, the two between the EG, and the surface 4 is between the BD and the FH. In the case of a column of books, even if the angle x in the X direction of the column changes, the horizontally installed surface 1 (elevating floor) is always horizontal, and the change in the X direction angle x causes surface 1 (elevating / lowering). The floor) descends and rises like i, b, c.

  In the above mechanical system, as shown in FIG. 4, E, F, G, and H portions are pin-joined, and the rotating direction variable motor 14 is lowered and raised when the descent and ascending movements are performed. Is lifted up and down by the pulleys 11 and 12 in the direction of the arrow (the direction of the motor). In addition, the shape of each detailed member for implementation is as FIG. 5, FIG.

  This elevator can be installed not only in newly built houses but also in existing houses and public facilities for other purposes, and it can be installed in a place where it can be placed directly in the room on the first floor besides the entrance hall. it can. In addition, it can be installed in a site space of 50% or less when a slope is provided, and it can accommodate buildings with different floor heights by adjusting the length of the four pillars.

  Further, conventional elevators that can be diverted for this purpose are not practical and are not widely used at present. The elevator according to the present invention can be easily used by a wheelchair user to go out and enter a room.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

  The elevator of the present invention is installed outside the entrance hall as shown in Fig. 1, and the appearance is as shown in Fig. 2.

  The structural form of the present invention is an elevator composed of the parallelogram and parallelogram laws of FIG. 3 and the mechanical system shown in FIG.

  The laws of the parallelogram and the parallelepiped will be described with reference to FIG. 3. In the parallel tetrahedron installed horizontally, the surface 1 (elevating floor) is always horizontal no matter how many times the angle x changes. Further, the surface 1 (elevating floor) rises and falls like i, b, c by the change of the angle x. In order to embody this law, the details, shape, and structure of each member will be described with reference to FIGS. 5 and 6. The U-shaped steel material 2 that receives the lifting floor 1 and the column head of the column 6 are screwed. The column cap 5 is connected to the pin, and the column base is also connected to the column cap 5 attached to the column base and the metal fitting 13 fixed to the base 18 provided on the ground. Furthermore, in order to keep the columns parallel, the connection is fixed by a steady rest 15 that serves as a stripe.

  A mechanical system used in combination with the above-described laws will be described with reference to FIG. 4. The joining portions E and F of the elevating floor 1 and the column 6 are pin-joined, and the G and H portions are also pin-joined and fixed to the base. When the rotation direction variable motor 14 winds the workpiece in the direction of the arrow, the elevating floor 1 descends. Further, when the rotation direction variable motor 14 winds the ascending wire rope 10 in the direction of the arrow, the elevating floor 1 rises. The details, shape, and structure of each member for embodying this mechanical system will be described with reference to FIGS. 5 and 6. When the lowering switch is pushed, it is attached to the column cap 5 on the column head. The wire rope 9 connected to the rope-connecting bracket 7 changes its direction at the pulley 11, and the rope 9 is wound in the direction of the arrow by the rotation direction variable motor 14, pulling down the pillar 6 and lowering the elevator floor 1. At the time of ascent, when the ascent switch is pushed, the wire rope 10 connected to the rope connecting bracket 8 attached to the elevator floor 1 changes direction with the pulley 12, and the rope 10 is wound in the direction of the arrow by the rotation direction variable motor 14. It is a mechanical system that is taken up and raises the lifting floor 1 by raising a pillar 6.

  The connecting method of the two winders attached to the rotational direction variable motor 14 and the wire ropes 9 and 10 which are essential to the present invention will be described with reference to FIG. The wire rope 9 for lowering is connected in such a manner that it is wound in the direction of B (reverse rotation). If one is wound by this connection method, one will be loosened. Another feature of this connection method will be described with reference to FIG. 5. When the descending wire rope 9 is wound in the direction of the arrow when descending, the function of the ascending wire rope 10 is loosened simultaneously (the role of the brake). ), It is possible to descend at a constant speed without sudden descent.

  The embodiment of the present invention will be described in accordance with the order of use. If the passenger enters the elevator from the entrance hall of the house as it is in the wheelchair and presses the lowering switch 20 in FIG. 1, the winding connected to the rotational direction variable motor 14 in FIG. When the machine winds down the descent wire rope 9 and descends while loosening the ascending wire rope 10 and arrives on the ground, the motor stops rotating by the action of the limit switch 22 in FIG. 1 and the elevator stops. When returning home, get on the elevator with the wheelchair, and if you use the ascending switch 21 in FIG. 1, the winder connected to the variable direction motor 14 in FIG. 5 winds the ascending wire rope 10 and descends. When the wire rope 9 is lifted while loosening and reaches the same height as the floor of the house, the rise is stopped by the limit switch 22 shown in FIG. 1 and can be returned to the entrance hall by itself. For safety, the elevating floor is provided with an L-shaped handrail 24 as shown in FIG. 1 and a cotton rope 25 with hooks on both ends that can be removed to prevent the fall.
