The present invention relates to a domestic lifting device. Here, stair lifts, etc. are excluded.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, various proposals have been made regarding home lifting devices that can be installed in detached houses with few floors. The objective effect is to reduce the human labor (including the inconvenience of stairs) in moving (transporting) people and objects, and to try to simplify the facility system on the premise of safety and economy. There was a point to do.

Regarding the mechanically operating lifting means of the present invention, a hydraulic elevator having a link-type lifting means is known, and a publicly known jack device (so-called screwdriver jack device) is vertically arranged in series. There is no particular match.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a hoisting device for home use which simplifies the equipment system on the premise of safety and economical efficiency and is easy to construct in new construction or (reduction) reconstruction. The purpose is.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that jack devices each having a driving source are vertically arranged in series as a mechanically operating link-type lifting means.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention according to a preferred embodiment, jack devices (screw-rotating jack devices) each having a drive source are vertically arranged on a lower surface of a cage, and are vertically moved to guide and fix the cage. Cage guide pillars with a U-shaped cross section are installed at the four corners of the road, and the two-stage rollers provided at the four corners of the cage are engaged, and the cage door and the floor door of the sliding door structure are linked and integrated. In order to perform a manual manual opening / closing operation, a door roller provided at one end of the cage door is formed on the back of each floor door to form a door guide groove that can pass through each floor when going up and down, and the drive source is turned on automatically. A limit switch for turning on / off is provided at a predetermined position, and is connected to the drive control means to be installed in a part of the house.

Then, the shaft of the jack device is driven by a motor to rotate in the forward and reverse directions, thereby expanding and contracting the links in the vertical (and left and right) directions to mechanically raise and lower the cage.

Here, the two-stage rollers provided in the cage are housed within the U-shaped cross section of the cage guide column, and the respective axial support directions are arranged in an orthogonal relationship (one in the horizontal direction and the other in the vertical direction). It is possible to suppress the swing of the cage.

Further, the door roller provided at one end of the cage door is a so-called floating piece, and is assumed to move up and down along with the cage along the door guide groove (when both doors are closed). This door guide groove is formed on the back of each floor door so that the door rollers can pass through each floor when going up and down. Then, after stopping at a predetermined floor, the cage door and the floor door can be made to cooperate with each other to open and close manually.

Further, limit switches communicating with the drive control means are provided at a plurality of predetermined positions so that the drive source is automatically turned on / off in accordance with a predetermined position and a predetermined state of the cage.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view explanatory diagram of an embodiment apparatus showing a state in which the first floor is stopped (the jack device is contracted in the vertical direction).

FIG. 2 is a front view explanatory diagram of the embodiment apparatus showing a state where the second floor is stopped (the jack device is extended in the vertical direction).

FIG. 3 is an explanatory plan view of the apparatus according to the embodiment.

FIG. 4 is a partial cross-sectional explanatory view showing the mounting structure of the two-stage roller provided in the cage.

FIG. 5 is a partial front view illustrating the disposition structure of the door guide groove.

FIG. 6 is an explanatory view of another embodiment device in which the type of the jack device is different.

In each of the figures, 1 is a cage, 11 is a cage door, 12 is a roller, 2 is a two-stage roller, 21 is an upper roller, 22 is a lower roller, 3 is a floor door, and 4 is a gear motor. -(Drive source), 41 is upper gear motor, 42 is lower gear motor, 5 is jack device (elevating means), 51 is upper jack device, 52 is lower jack device, 6 is limit switch, 7 is cage guide A pillar (groove-shaped steel), 8 is a guide groove for a door, 9 is a hoistway, 10 is drive control means, and X is a household hoisting device.

As shown in FIG. 1 and FIG. 2, the mechanically operated lifting means is a jack device (5; 51, 52), which is vertically arranged on the lower surface of the cage (1) and individually driven. It has a source gear motor (4; 41, 42). Here, as shown in the figure, it is usually installed on the foundation below the first floor for the first and second floors, but since the jack device itself can be compactly housed in the vertical direction, the second and third floors are installed. It is also possible to install it under the floor on the second floor.

In the illustrated jack device (5), the threading of the shaft is in one direction, and in the figure, the right end of the link is fixed free from the shaft rotation. Therefore, when the left end of the link is displaced by the rotation of the shaft and the link expands and contracts, the gear motor (4) also follows the shaft at its right end in up, down, left, and right directions (specifically, in the up / left direction or the down / right direction). [Fig. 2]

Further, as shown in FIG. 6, it is of course effective to use a jack device (5) having a shaft with left and right threads separately threaded from the center toward the end. In this case, even if the link expands and contracts, the shaft does not move to the left and right, the drive source [the gear motors for both shafts] (4) only moves up and down, and there is an advantage that the expansion and contraction operation is fast. However, the drive source (4) is located at the center of the shaft, and its fixed guide (not shown) is required in the ascending / descending direction. However, this configuration does not pose any difficulty in construction.

As shown in FIGS. 3 and 4, the cage guide column (7) is a steel member (groove-shaped steel) having a U-shaped cross-section that opens into the hoistway (9) and has a cross-section. The two-stage rollers (2; 21, 22) provided in the cage (1) with a shape of a roller guide are housed in the cross section to guide the cage (1) vertically (up and down).

The two-stage rollers (2; 21, 22) are arranged such that their axial support directions are orthogonal to each other (one in the horizontal direction and the other in the vertical direction). The movement can be suppressed.

Further, as shown in FIG. 5, the door guide groove (8) is provided on the back surface of each floor door (9), and when the door is closed, there is a single passageway through each floor (of course, between the upper and lower floors). The door roller (12) [so-called floating top] provided at one end of the cage door (11) can be passed in the vertical (up and down) direction. At the stop position of the predetermined floor, the cage door (11) having a sliding door structure and the floor door (3) are made to cooperate with each other via the door roller (12) to integrally open and close manually.

That is, since the door roller (12) is provided on the cage door (11) and engages with the door guide groove (8) of the floor door (3), the cage (1) is moved from inside the cage (1). When the door (11) is pulled or the floor door (9) is pulled (manually opened / closed) from outside the cage (1), one of them (floor door or cage door) is carried. Here, each door in the closed state is preferably held by using a magnet. The device will not be driven (elevated) unless the door is closed by the limit switch described below.

Further, limit switches (6) are provided at the elevator stop position of the cage (1) and the closed position of the cage door (11) on each floor, and a predetermined position (via a drive control means (10) ( The automatic ON / OFF of the gear motor (4) is controlled according to the (elevation stop position) and a predetermined state (door closed state).

[0027]

[Effect of device]

 The present invention has the above-mentioned configuration, and according to this, the facility system can be further simplified on the assumption of safety and economic efficiency, and it can be used for the first and second floors or 2, or 2 It can be constructed as a lifting device for the 3rd floor and is easy to install.

In particular, since the jack devices are connected in series, the lifting device can be efficiently moved up and down, and the function and effect of the home lifting device can be improved.
