[Problems to be solved by the invention] By the way, among the conventional elevator sills as described above, the former sill 3 made of aluminum or the like has the problem that it is easily corroded and worn out, has poor durability, and has a short lifespan. It was hot. In addition, the latter sill 3a made of stainless steel or the like can improve durability, but requires machining to cut out a thick plate, resulting in high manufacturing costs.
There was a problem with the increased weight.

The present invention was made in view of the above-mentioned actual situation in the prior art, and its purpose is to provide an elevator sill that can be formed from a thin plate made of rustless metal.

[Means to solve the problem]

To achieve this purpose, the present invention provides an elevator sill that is installed at one end of the floor and extends along one end of said floor at the threshold of the elevator where a groove is formed that engages the lower end of the elevator door. The top plate that is
A pair of side plates are adjacent to each other through the bent portions at both ends of this upper plate, and a pair of side plates are adjacent to each other through the bent portions to the lower ends of these side plates, and are opposed to each other so as to sandwich an opening with open ends for bolt insertion. is placed,
a main member having a pair of lower plates fixed to the floor; a substrate provided between one of the pair of lower plates of the main member and the floor; a standing plate adjacent to one of the side plates through the bent portion and arranged at a predetermined distance from one of the side plates; and adjacent to the upper end of the standing plate through the bent portion and extending in a direction away from the main member. It is composed of a horizontal plate and a subordinate member having a horizontal plate arranged thereon.

[Effect]

Since the present invention is constructed as described above, the main member consists of an upper plate, a pair of side plates, a lower plate, etc., which are adjacent to each other through the bent portions, and are installed at one end of the floor, and along the main member. Subordinate members are arranged in parallel, each of which consists of a board, a standing board, a horizontal board, etc. adjacent to each other via a bent portion, and is installed on the floor via a base. The upright plate of the subordinate member is arranged at a predetermined distance from one of the side plates of the main member, and a groove having a predetermined width is formed by the upright plate and the side plate. Further, the horizontal plate and the upper plate adjacent to the upper end of the vertical plate and the upper end of the side plate, respectively, are arranged in a direction away from each other and cover both sides of the upper part of the groove. Thereby, the threshold of the elevator can be formed by bending a thin plate made of rust-free metal such as stainless steel.

Since the subordinate member 14 and the subordinate member 14 are constructed separately, by changing the subordinate member 14 to another subordinate member, such as the subordinate member 9 in FIG. 1, and providing it together with the main member 8, various numbers of doors can be installed. It can be applied to elevators with

[Effect of idea]

Since the present invention is configured as described above, it can be formed from a thin plate made of non-corrosive metal such as stainless steel, and therefore, due to improved durability, the lifespan is doubled compared to those made of aluminum etc. It can be extended beyond that. Additionally, compared to those made by machining thick plates such as stainless steel, the manufacturing cost can be reduced by about 80%, and the weight can be reduced by 65%.

In addition, the fixing bolt is inserted through the open end of the opening provided in the main member.
The opening with open ends can be formed at the same time as the main member is formed by bending the thin plate, and the opening can be easily formed. Furthermore, whether one groove or two grooves are provided to engage the lower end of the elevator door, the main member can be used for both, so it is necessary to prepare a member in advance for two types of sills with different numbers of grooves. It also has the effect of requiring fewer points.
