Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator car equipped with a trunk, such as a residential elevator, and its object is to provide an elevator car with a trunk that is simple in structure and easy to install. It is on offer.

According to regulations, residential elevators installed in residential buildings must have trunks that can accommodate stretchers and coffins.The trunks are applicable to 9-seater elevators and have a frontage of 950mm and a height above the floor.
It is defined as 1000mm from a position below 100mm and 480mm in depth, and a door is installed in the front and locked. Residential 9
When installing a trunk in a passenger elevator, it is structurally superior to attach the trunk part to the passenger car in one piece. Since the elevator was fixed using bolts, a lot of time was spent installing the elevator.

The present invention is an improvement on this point of the conventional scheme, and the object is to obtain an elevator car that utilizes the floor structure of the trunk-less type as it is and has a structure with a trunk by simply adding some accessories. .

The present invention will be explained below based on Examples.

Figures 1 to 3 show the conventional structure, where 1 is the floor;
2 is the baseboard, 3 is the front pillar, 4 is the car side board, 5 is the car rear side board, 6 is the ceiling board, 7 is the underlay for the trunk, 8 is the side board, 9 is the rear board, and 10 is the trunk top board. 11, 11' are trunk doors, and 12 is a cylinder lock. The trunk is attached to the residential nine-seater elevator shown in Figure 1 and is normally locked. When it is necessary to carry a stretcher, coffin, etc., the cylinder lock 12 is unlocked (the locking device is not shown) and the trunk doors 11, 11' are opened. Here, the trunk structure will be explained with reference to FIG. 3. The trunk is constructed by welding a steel plate to the trunk box as a strength member to form the trunk floor. Side plates 8, rear plate 9, and top plate 10 are attached by bolts (not shown). ), and the doors 11 and 1 are attached to the front part.
1', a door shaft 13 is attached to the upper and lower parts of the door, a door bearing 15 supporting this is fixed to the box body with a fixing bolt 16, and a lubricant sheet 14 is attached to the lower shaft part.
The structure is such that the doors 11, 11' are rotated by the rotation of the doors 11, 11'. Next, holes are made by welding metal fittings 19 on the car side that is attached to the car, the upper part at any position on the rear side plate 5 of the car, and the lower part at any position on the floor 1.
A corresponding hole is also provided on the side of the trunk box, and the structure is such that the trunk can be mounted with bolts at the trunk installation height H (100 mm or less) from the floor as determined by regulations. The conventional plan has the following drawbacks. When attaching a trunk box to a passenger car at an elevator installation site, the box is suspended using a chain block, and the holes in the car and box are aligned and tightened with bolts, but since there are multiple holes, it is difficult to ensure levelness and verticality. It took a lot of adjustment time to get the temperature right.

The present invention addresses the above-mentioned problems, and an embodiment of the present invention is shown in FIG. 4 below. FIG. 4 is a detailed explanatory view of the trunk according to the embodiment of the present invention. The box of the trunk structure is the same as the conventional one, but the method of attaching it to the car is different from the structure of the car floor 1 compared to the floor structure without a trunk. Supporting metal fitting 20 having a horizontal side and a vertical side
are welded and integrated so that the vertical sides are on the outside to form a floor structure with a trunk. The horizontal side and the vertical side of the support fitting 20 must be in such a relationship that the vertical side hangs down from the end of the horizontal side, and the support fitting 0 in FIG. is in the above relationship. On the other hand, a vertical portion is formed in both the strength member and the vertical member of the underlay 7, and this portion is used to attach it to the car floor side, and this vertical portion is engaged with the horizontal side of the support fitting 20. However, a positioning piece 21 that defines the height H between the car floor and the trunk floor is welded. This positioning piece 21 is welded (using a jig) at a dimension A position with the trunk floor as a reference during factory manufacture. Further, the positioning piece 21 is welded to the middle part of the vertical part, and the part below the positioning piece 21 of the vertical part is fixed to the vertical side of the support fitting 20 by bolting.

According to an embodiment of the present invention, the task of installing a trunk to a car at an elevator installation site is carried out by using a chain block to hold the trunk box body on the floor.
The horizontality and verticality of the trunk can be easily determined by simply placing the positioning piece 21 on top of the trunk. With this position positioned, attach the vertical part to the vertical side with the bolt 1.
8, the positioning piece 21
By engaging with the support fitting 20, the position of the trunk will not shift during this bolt tightening work, and the trunk can be stably and easily installed in a fixed position.

As described above, according to the present invention, there is no need for the conventional adjustment time when installing a trunk, and an elevator car with a trunk that is easy to construct can be provided.

Claims (1)

[Claims] 1 An underlayment formed by fixing a steel plate to a strength member to form a trunk floor, side plates provided on both sides of this underlayment, a rear plate connected to this side plate, and an upper plate provided over the upper part of this rear plate and side plates. A box is formed with an opening on the front side, and a door is pivotally supported in the opening of the box to form a trunk. In an elevator car in which a trunk is attached so as to protrude outward from the car, a supporting metal fitting having a horizontal side and a vertical side that is connected to the end of the horizontal side and hangs down is attached to a component of the car floor so that the vertical side rests on the car floor. At the same time, a positioning piece that engages with the horizontal side of the support fitting and defines the height between the trunk floor and the car floor is welded to the strength member of the underlayment so as to face the outside of the car. An elevator car, characterized in that the strength member and the vertical side of the support fitting, which face each other at the engagement position between the horizontal side of the support fitting and the positioning piece, are fixed by bolts.
