Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a threshold device for an elevator landing.

[Technical background of the invention]

2. Description of the Related Art Conventionally, a threshold device provided at the lower edge of an entrance of an elevator hall has a configuration as shown in FIGS. 1 and 2.

That is, in FIGS. 1 and 2, 1 is the sill main body;
Reference numeral 2 denotes a plurality of brackets 1- that support the sill main body 1 at multiple locations, and the brackets 2 are made of steel material such as angle material bent in an inverted shape, and are anchored to the hoistway wall △ at the vertical part. It is fixed with bolts 3 and nuts 4.

Further, as the sill body 1, generally, a drawn or extruded product made of hard aluminum is used in consideration of weight reduction and economy, and the upper surface of this sill body 1 is provided with a guide door 5. A door guide groove 6 is formed. The upper surface of this threshold body 1 is the elevator landing floor B.
It is supported on the horizontal part of each bracket 2 via a backing plate 7 so as to be flush with the bracket 2, and is fixed to the bracket 2 by a fastening bolt 8 and a nut 9.

The bolt head 8a of the fastening bolt 8 fits into a bolt holding groove 10 formed on the back side of the threshold body 1 over its entire length and has bolt receiver flanges on both sides of the lower end, so that the bolt head 8a is not pulled out downward. It is held in the sill main body 1 like this.

This threshold device first attaches a plurality of brackets 2 to the hoistway wall A.
It is installed at the lower edge of the entrance by fixing the sill main body 1 on each of the brackets 2. A plurality of fastening bolts 8 are attached to the end of the bolt 10.
After inserting the heads 8a and aligning the respective fastening bolts 8 with the positions of the respective brackets 2, the sill main body 1 is lowered onto the brackets 2, and each fastening bolt 8 is attached to the backing plate 7 and the bracket 2.
This is done by passing the bolt 8 through a bolt insertion hole provided in the bracket 2, and screwing a nut 9 onto the bolt 8 from below the bracket 2 and tightening it.

[Problems in the background art] However, when installing the conventional sill device described above, the plurality of brackets 2 must first be attached to the hoistway wall A so that the top surfaces of all the brackets are aligned at the same level. 2 and its height adjustment is very troublesome, and the sill body 1 is attached to the bracket 2.
If the fastening bolts 8 held in the sill main body 1 do not enter the bolt insertion holes of the backing plate 7 and the bracket 2 well when lowering it upward, and hit the top surface of the backing plate 7, the fastening bolts 8 will break through the backing plate 7.
The sill body 1 may be pushed up into the bolt holding groove 10 of the sill body 1 and fall down, and in this case, the fastening bolt 8 cannot be tightened, so the sill body 1 must be removed from the -H bracket 2. Since the installation of the sill main body 1 has to be done again from the beginning, the conventional sill device has a problem in that it takes a lot of time and effort to install it.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and its purpose is to enable installation at the lower edge of the passenger entrance easily, in a short time, and with good workability. An object of the present invention is to provide a threshold device for an elevator landing.

[JR Invention Key]

That is, the present invention has a structure in which a bracket portion supporting the sill body is integrally formed with the sill body, and the sill body is installed at the lower edge of the entrance with the bracket portion fixed to the hoistway wall.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Components in the figure that correspond to those shown in FIGS. 1 and 2 are given the same reference numerals, and their explanations will be omitted.

In FIGS. 3 and 4, reference numeral 11 denotes a sill main body, and this sill main body 11 has a structure in which a bracket part 12 that supports this sill main body 11 is integrally formed at its base. The sill main body 11 and the bracket part 12 are integrally formed by bending a plate material such as an iron plate or a hard aluminum plate by roll forming, etc. In this embodiment, the metal plate is formed into a substantially U-shape. It is bent to form a hollow threshold body 11, and four door guide grooves 6 are formed in the upper horizontal plate part, and the base ends of the upper and lower horizontal plate parts forming this threshold body 11 are 2.Fold each side downward and touch each other.
A bracket portion 12 is formed of two vertical plates.

Further, an inclined plate portion is formed between the lower horizontal plate portion of the sill body 11 and the inner vertical plate of the bracket portion 12 bent from this, and therefore, the load applied to the sill body 11 is reduced. , so that it can be reliably transmitted to the bracket part 12 via this inclined plate part.

The sill main body 11 is fixed by tightening the bracket part 12 to the hoistway wall A with anchor bolts 3 and nuts 4, so that the upper surface of the sill main body 11 is aligned with the landing floor B surface and the road surface. It is installed at the lower edge of the entrance.

However, since this sill device has a structure in which the sill body 11 and the bracket part 12 that supports it are integrally formed, the installation is done by aligning the top surface of the sill body 11 with the surface B of the landing floor. This can be accomplished by a simple operation of fixing the bracket part 12 to the hoistway wall A. Therefore, with this sill device, unlike conventional sill devices, there is no need to adjust the height of the brackets so that the top surfaces of all the brackets are at the same level when installing the brackets on the hoistway wall. Since the installation of the sill body does not require any work, there is no problem of the fastening bolts falling down when installing the sill body to the bracket, which was the case in the past.
A threshold device can be easily installed at the lower edge of an entrance/exit in a short time with good workability.

In addition, in the above embodiment, the threshold main body 11 and the bracket part 12
The sill main body 11 is formed by integrally forming a plate material by bending process such as roll forming process.
The bracket portion 12 may be integrally formed by drawing or extrusion of hard aluminum or the like and have a shape as shown in FIG. 5.

〔Effect of the invention〕

According to this invention, the installation at the lower edge of the entrance/exit can be easily performed in a short time and with good workability.
