Description

The present invention relates to the structure of a door used in an elevator hall.

[Prior Art] Doors of elevator halls used for buildings are generally installed on the floor of the hall by running the wheels mounted on the top of the hall doors on the upper rails that are installed horizontally at the top of the hall. It is configured to engage and disengage the leg portion attached to the lower portion of the door in the groove of the lower rail provided.

FIG. 5 is a front view of a conventional elevator hall door, and FIG.
FIG. 7 is a sectional view thereof, FIG. 7 is a perspective view showing the structure of the door, and FIG.
FIG. 9 is a perspective view of the lower part of the door, and FIG. 9 is a cross-sectional view of the lower part of the door.
Is an upper reinforcement member, 4 is a lower reinforcement member, 5 is a front plate, 6 is a wheel attached to the upper portion of the door 1, 7 is a leg portion attached to the lower portion of the door 1, 8 is a bolt, 9 is an elevator doorway Is an upper rail horizontally arranged on the upper part of the, and a lower rail 10 is formed on the floor of the entrance / exit of the elevator to form a groove 10a.

As shown in FIG. 7, the door 1 has an upper reinforcing member 3 attached to an upper portion of a main body frame 2 formed of a steel plate, a lower reinforcing member 4 attached to a lower portion thereof, a wheel 6 attached to the upper reinforcing member 3 and a lower reinforcing member 4 attached to the lower reinforcing member 4. The leg portion 7 is attached by a bolt 8.

In manufacturing the door 1, a steel plate is molded as shown in FIG. 7 to form a main body frame 2, and an upper reinforcing member 3 is welded to an upper portion thereof and a lower reinforcing member 4 is welded to a lower portion thereof. . The surface of the front plate 5 is a design surface facing the landing. Further, the wheels 6 are attached to the upper reinforcing member 3 as shown in FIG. 6, and the leg portions 7 are fastened to the lower reinforcing member 4 with bolts 8 as shown in FIG. The lower reinforcing member 4 is
It is formed by molding a steel plate as shown in FIG. The conventional elevator hall door is configured as described above.

In this door 1, the wheels 6 on the top are placed on the upper rails 9 to suspend the door body, and the wheels 6 travel on the upper rails 9,
The legs 7 run in the groove 10a of the lower rail 10 to open and close the door 1.

[Problems to be Solved by the Invention] By the way, in the door of the landing, the dimensions such as the height, width and thickness of the door 1 are different depending on the specifications of the elevator landing, and therefore the specifications of the lower reinforcing member 4 are also each door. It depends on each. Therefore, when manufacturing the door 1, the lower reinforcing member 4 must be designed and manufactured only for the door according to the specifications of each door. In other words, there are only the types of lower reinforcing materials for the types of doors, which takes time and labor for managing members, complicates manufacturing and assembling thereof, and results in variations in quality.

Further, in manufacturing the conventional door, the upper reinforcing member 3 and the lower reinforcing member 4 are attached to the main body frame 2 mainly by welding as described above. If there are many welding points, distortion due to welding tends to occur on the design surface of the front plate 5 of the door, and in order to make this welding distortion inconspicuous, it is necessary to repair it with putty etc. at the time of painting, which is troublesome. Will be taken. The conventional elevator doors have the above-mentioned problems mainly in terms of manufacturing.

The present invention has been made in order to solve the above problems of conventional doors, and the shape of the member of the lower reinforcing member is unified regardless of the difference in the specifications of the door to reduce the number of types, and the production control at the time of production is performed. The purpose of the present invention is to provide an elevator landing door that is easy to assemble and that eliminates welding in assembling the lower reinforcing member to minimize the occurrence of welding distortion and stabilizes the quality.

[Means for Solving the Problems] In order to achieve the above object, the lower reinforcement member for a door of an elevator landing according to the present invention has a lower end portion of a main body frame of the door molded in a U shape, and the door is provided at a rising portion thereof. A leg mounting member molded into a predetermined shape for mounting the leg is mounted.

The specifications of the leg mounting members are the same or the types thereof are minimized regardless of the specifications of the door.

[Operation] Since the specifications of the leg mounting members that form the lower reinforcing member of the door are narrowed down to the same or minimum types regardless of the specifications of the door, it is troublesome to perform work in manufacturing and assembling the lower reinforcing member. And the management of parts becomes easier.

Further, since welding is abolished in the assembly of the lower reinforcing member and fixed by, for example, rivets, welding distortion does not occur.

[Embodiment of the Invention] FIG. 1 is a perspective view of an elevator landing door which is an embodiment of the present invention, and FIG. 2 is a perspective view showing the structure of a lower reinforcing member of the door. Same as or equivalent to the device, 11
Is a lower reinforcing member, 12 is a frame body, 12a is a rising portion thereof, 12b is a bottom portion thereof, 13 is a leg attaching member, and 14 is a rivet.

As shown in the figure, attach the lower reinforcement 11 of the door to the frame body.
The lower end portion of 12 is formed into a U shape having a bottom portion 12b and a rising portion 12a, and a leg mounting member 13 formed into a U shape is fixed to the rising portion 12a with a rivet 14. The leg attaching member 13 is fixed to the door 1 of various specifications regardless of the specifications such as the height, width and thickness of the door, or is unified to the minimum specification.

The lower reinforcing member 11 of the door configured as described above has a corresponding strength, and the specifications of the leg mounting members 13 are constant regardless of the specifications of the door or the types of the specifications are unified to the minimum. Therefore, it can be mass-produced in a dedicated press die, and its dimensional accuracy is improved. Further, even when the lower reinforcing member is assembled, since it is fixed with the rivets, the labor and time for producing and assembling the lower reinforcing member 11 are not required. Further, since welding is not used for assembling the lower reinforcing member 11 as described above, welding distortion does not occur on the design surface, and workability is improved accordingly.

3 and 4 are an enlarged perspective view and a sectional view showing the structure of the lower portion of the door, and the leg portion 7 of the door is attached to the leg attaching member 13 by the bolt 8 as shown in the drawings.

The shape of the leg attachment member 13 is not limited to the shape shown in this embodiment, and other shapes may be adopted. Also, the number is not limited to two in this embodiment, and the number may be increased or decreased according to the specifications of the door.

[Effects of the Invention] An elevator hall door according to the present invention is configured such that a lower reinforcing member is formed in a U-shape at a lower end portion of a main body frame, and a leg attaching member is attached to a rising portion thereof. Since the specifications of the leg mounting members are constant regardless of the specifications of the door or the types of the specifications are minimized, the following excellent effects are achieved.

(1) Regardless of the door specifications, the leg mounting members have the same or minimum types of specifications, which facilitates the member management in the door manufacturing and also allows the manufacture of the lower reinforcement and the incorporation into the door. Man-hours are reduced, and variations in quality are reduced.

(2) Since welding is abolished in the assembly of the lower reinforcing member and fixed by, for example, rivets, welding distortion does not occur and workability is improved.

(3) Since the members of the lower reinforcing member 11 can be painted before assembling, there is no fear that the screw holes will be crushed by the paint, and the door leg 7
It becomes easy to install and adjust.
