In this case, the connecting piece 23 has a substantially U-shaped cross section and a predetermined length smaller than the depth of the cab body of the home elevator. It is formed with a width dimension that engages with the inside of the character shape. In this case, three connecting pieces 23 are fixed by welding at predetermined intervals so as to connect the projecting pieces 21, 21 so as to connect the projecting pieces 21, 21. To support.

The car mounting part 3 has vertical pieces 31 on both sides having a substantially L-shaped cross section which constitute a mounting surface on which the car room is mounted.
And a fixing portion 33 for attaching the car mounting portion 3 to the projecting pieces 21 of the platform main body 2, which is provided so as to be orthogonal to the rear surface side so as to connect the vertical pieces 31, 31. It has attachment pieces 32, 32 having a substantially L-shaped cross section, and reinforcing pieces 34, 35 provided vertically and horizontally to reinforce the state in which the vertical pieces 31, 31 and the attachment pieces 32, 32 are connected. It is composed.

The vertical pieces 31, 31 have a door support piece 37 for supporting a door provided in the cab projecting from the front end thereof, and have an asymmetric shape in the front and rear width direction with respect to the vertical frame 5, so that the cab is formed. A plurality of long holes 38 for fixing the cab main body are formed in the mounting surface on which the cab is mounted. Also, the attachment pieces 32, 32
Is an L-shaped hanging part 33, the car mounting part 3
Corresponding to the fixing holes 24, 24 of the protruding pieces 21 provided on the front and rear of the platform main body 2 so as to be able to be fixed to the protruding pieces 21, 21 of the platform main body 2 independently of the front and rear with respect to the vertical frame 5. At the location, fixing holes 36, 36 into which the bolts 41 for fixing the car placing portion 3 are inserted are provided.

In the car mounting portion 3 having the above-described structure, the attachment pieces 32, 32 are formed by the projecting pieces 21, 21 of the platform body 2.
The vertical pieces 31, 31 are spaced at such a distance that they can be engaged with
Are fixed to each other by welding.
And reinforcing pieces 34 to connect the attaching pieces 32, 32,
35 is formed by being fixedly provided by welding.

The elevator platform 1 having the above configuration is constructed by combining the platform main body 2 and the car mounting portion 3 on which the elevator cab is mounted when the cab is provided on the hoistway of the home elevator. . That is, first, the platform 1 is such that the platform body 2 is inserted into the fixing holes 25 of the frame fixing portion 22 in the vertical frame 5 guided by the guide rail provided on one side of the hoistway, The nut 26 and the nut 42 are screwed and fixed, and project from the vertical frame 5 in the horizontal direction. Next, a car mounting portion 3 which is formed separately from the platform main body 2 and has an outer shape substantially corresponding to the bottom shape of the cab main body having different sizes is provided above and combined therewith, and a plurality of different sizes are provided. It will be constructed corresponding to the elevator cab. Therefore, when corresponding to elevator cabs of different sizes corresponding to the number of boardable personnel, only the car mounting portions 3 having different external shapes need to be prepared.

The car mounting portion 3 is provided on a side of a protruding piece 21 protruding from the vertical frame 5 of the platform main body 2 in the horizontal direction, and a fixing portion 33 which is formed so as to extend downward from the mounting surface. Are fixed and positioned in the front-rear direction to be combined with the platform main body 2. Also, in this case, the landing position with respect to the guide rail provided on the hoistway, that is, the difference in the direction of opening the door of the cab, is determined in accordance with the predetermined direction of hand, and the width direction of the front and rear with respect to the vertical frame 5. The asymmetric car mounting part 3 is
And fixed to the vertical frame 5 at different front and rear positions.

Therefore, according to the elevator platform described above, the platform on which the cab of the elevator is mounted is directed laterally from the vertical frame 5 guided by the guide rail provided on one side of the hoistway. Combining the projecting platform body 2 and the car mounting portion 3 provided above and having the outer shape substantially corresponding to the bottom shape of the differently-sized cabs provided above the plurality of different sizes, Since it is possible to correspond to the elevator cab, it is possible to easily adapt to the difference in the size of the cab with a small number of varieties according to the change in the number of boardable persons.

A fixing portion 33 which is formed to extend downward from the mounting surface of the car mounting portion 3 is provided on the side of the projecting piece 21 which is provided to project laterally from the vertical frame 5 of the platform body 2. , And can be combined with the platform body 2 to easily perform positioning in the front-rear direction and fix the combination, thereby shortening the construction time. In addition, vertical frame 5
Since the car mounting portion 3 which is asymmetrical in the front and rear width directions is fixed to the projecting piece 21 of the platform main body 2 with respect to the vertical frame 5 so as to be able to be combined with the platform main body 2, the door can be assembled. It is possible to cope with the difference in the opening direction by using one kind of car mounting part 3,
It is possible to meet the cab specifications with a smaller variety.

In the elevator platform according to the present invention, in addition to the above-described integrally formed car mounting portion, the car mounting portion 3 is divided into front and rear portions as shown in FIG. The portions 39, 39 and the platform body 2 may be formed in combination. In this case, the car mounting part 39 is fixed to the side of the protruding piece 21 as shown by the arrow B, and the fixing part 33 formed by bending one edge of the car mounting part 39 is fixed to the side of the narrow hoistway. The effect that it is easy to provide is produced.

[0029]

As described above, in the elevator platform according to the first aspect of the present invention, the platform on which the cab of the elevator is mounted is vertically guided by the guide rail provided on one side of the hoistway. Combining a platform body protruding from the frame in the lateral direction and a car mounting portion having an outer shape substantially corresponding to the bottom shape of the cab of different size provided separately above and provided above the platform body Since it is possible to correspond to a plurality of elevator cabs having different sizes, it is possible to easily adapt to a change in the number of occupable personnel and a small variety of cabs having different sizes.

According to a second aspect of the present invention, in addition to the effects of the first aspect, the elevator platform further includes a fixing portion which is formed to extend downward from the mounting surface of the car mounting portion, and a vertical frame of the platform body. Since it is fixed to the side of the protruding piece protruding in the lateral direction and combined with the platform body, positioning in the front-back direction can be easily performed and the combination can be fixed, thereby shortening the construction time.

Further, the elevator platform according to the third aspect has the effects of the first or second aspect,
The car mounting part, which is asymmetrical in the width direction in the front and rear direction with respect to the vertical frame, is fixed to the protruding piece of the platform body in a different way from the vertical frame and can be combined with the platform body. The difference can be handled by the car mounting part of one kind, so that the number of kinds can be adjusted to the car room specification.
