Abstract

PURPOSE:To easily remove small stones, etc. by forming a guide groove into a cross sectional form having the wider width on the bottom side than on the upper surface opened port side, forming an inclination on the side wall of the guide groove formed on a threshold. CONSTITUTION:A guide groove 6a is formed into a cross section surface having the wider width on the bottom 6b side than on an upper surface opened port 6e side by forming an inclination on the side wall 6d of the guide groove 6a. Therefore, even if a solid foreign substance 11 such as small stone having the equal size to the width A of the upper surface opened port part 6e of the guide groove 6a intrudes into the guide groove 6a, the foreign substance 11 is prervented from being nipped firmly between the both side walls 6d of the guide groove 6a, and pushed by a guide piece 10 in opening and closing of a door 4, and dropped onto the bottom part 6b of the guide groove 6a. Since the width D of a trash dropping hole 6c on the bottom 6b of the guide groove 6a is set larger than the width A of the opened port part 6e of the guide groove 6a, the small stone 11 which is dropped onto the bottom part 6b is dropped below a threshold 6 from the drop hole 6c, and can be easily removed.

It's a door. As shown in FIGS. 5 and 6, a sill 6 is installed at the end of the hoistway 5 side of the landing floor 1, and the sill 6 is provided with anchor bolts 7a and nuts 7b on the hoistway 5 side of the landing floor 1. It is fixed to a sill support 8 fixed by a mounting bolt 9a and a nut 9b. The sill supports 8 are arranged at a plurality of locations in the longitudinal direction of the sill 6, that is, in the width direction of the doorway. Further, as shown in FIGS. 7 and 8, the sill 6 is formed with a guide groove 6a having an upper surface opening and a vertically rectangular cross section over the entire length in the longitudinal direction.
In the bottom 6b of a, there is a dirt hole 6c at an appropriate position in the longitudinal direction.
is provided, and the garbage pit 6c opens on the lower surface of the sill 6,
Moreover, it is configured in a planar shape that is elongated in the longitudinal direction. The guide groove 6a is fixed to the lower end of the above [4].
A guide piece 10 protruding downward from the lower end of the door 4 is inserted. The guide pieces 10 are disposed on the left and right sides of the door 4, and are configured to slide within the guide groove 6a when the door 4 is opened and closed. In addition, in FIGS. 5 and 8, 6d is the guide groove 6.
In the side wall of a, 11 in FIG. 8 is a pebble caught in the guide groove 6a.

In the elevator threshold device configured as above, the guide groove 6
When the doors 4 of the landing are opened and closed, the garbage that has entered inside the hall is pushed by the guide pieces 10 protruding from the lower ends of these doors 4, and is usually dumped into the threshold through the garbage drop hole 6c provided at the bottom 6b of the guide groove 6a. 6 to keep the inside of the guide groove 6a clean.

[The problem that the invention tries to solve! ! ] The conventional elevator sill device is constructed as described above, and since the guide groove 6a formed in the sill 6 has a rectangular cross section, as shown in FIG. If a hard foreign object such as a small stone mason 1 of similar size enters, it will be caught between the both side walls 6d of the guide groove 6a. Pebbles 11 and the like that are firmly caught between the both side walls 6d of the guide groove 6a can be removed from the guide groove 6a of the guide piece 10 by opening and closing the landing door 4.
It cannot be removed just by moving the guide piece 10 inside, and may hinder the movement of the guide piece 10, causing trouble in opening and closing R4.

In addition, the dirt hole 6C provided at the bottom 6b of the guide groove 6a is
As shown in FIG. 8, since the width is 8 dimensions narrower than the width A of the guide groove 6a, even if a pebble 11 moves, it will remain in the guide groove 6a without passing through the dirt drop hole 6c. While staying inside and being pushed and moved by the guide piece 10 of the door 4 several times, the pebbles 11 and the like often roll and change direction, becoming firmly wedged between the side walls of the guide groove 6a. There was a problem.

This invention was made in order to solve the above-mentioned problems. It is difficult for hard foreign objects such as pebbles to get caught between the side walls of the guide groove of the sill, and it also prevents foreign objects such as pebbles from getting into the guide groove. The present invention also aims to provide an elevator sill device that is easy to remove.

[Means for Solving the Problems] The elevator sill device according to the present invention is provided with an inclined surface extending from the top opening side to the bottom side on the side wall of the guide groove provided in the sill, so that the side wall of the guide groove provided in the sill is provided with an inclined surface facing from the top opening side to the bottom side. The guide groove is formed in a wide cross-sectional shape.

[Function] The elevator sill device according to the present invention has an inclination on the side wall of the guide groove to form the guide groove in a cross-sectional shape that is wider on the bottom side than on the top opening side. Even if a hard foreign object such as a pebble of the same size as the width of the guide groove enters the guide groove, it will not be firmly caught between the side walls of the guide groove, but will be pushed by the guide piece when the door is opened and closed, and will be pushed to the bottom of the guide groove. drop down. By making the width of the dirt drop hole provided at the bottom of the guide groove larger than the width of the opening of the guide groove, pebbles, etc. that have fallen to the bottom as described above will fall from the dirt drop hole to the bottom of the sill. , can be easily removed.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1, 2, and 3, the same reference numerals as in FIGS. 4 to 8 indicate corresponding parts.

In this embodiment, both side walls 6 of the guide groove 6a provided in the sill 6 are
d is formed such that only the portion close to the upper surface opening 6e is vertical and parallel to each other, and the parallel surface 6a and the bottom 6b (I!) are gradually formed downward from the opening 6e side to the bottom 6b side. An inclined surface 6d is formed to increase the width. That is, the guide groove 6a is formed with a parallel surface 6 on the side of the opening 6e.
The width dimension C of the bottom 6b portion is larger than the width dimension A of the d1 portion. In addition, in this embodiment, the width dimension of the plurality of dirt drop holes 6c provided in the bottom 6b of the guide groove 6a and opening to the lower surface of the sill 6 is parallel to the parallel surface 6.
It is formed larger than the width dimension A of L.

The configuration and basic operation of this embodiment other than those described above are the same as those of the conventional elevator sill device shown in FIGS. 4 to 8.

The elevator threshold device according to this embodiment has a guide groove 6a.
Since the inclined surfaces 6dx are formed on both side walls 6d of the guide groove 6a so that the width dimension C of the opening 6e side of the guide groove 68 is increased, the width dimension A of the opening 6e side of the guide groove 68 is increased as shown in FIG. If a hard foreign object such as a pebble 11 of the same size enters the guide groove 6a, the guide piece 10 that protrudes downward from the lower end of the landing door 4 and is inserted into the guide groove 6a will be removed from the door 4. By moving along the longitudinal direction of the guide groove 6a as the guide groove 6a opens and closes, the guide groove 6
The pebble 11 that has entered inside a is the moving guide piece IO.
It is pushed by the guide groove 6a, falls to the bottom 6b of the guide groove 6a, and is not firmly caught between the side walls 6d of the guide groove 6a. Pebbles 11 and the like that have fallen to the bottom 6b of the guide groove 6a, such as the width of the dirt drop hole 6c provided at the bottom 6b of the guide groove 6a, are removed from the dirt drop hole 6c to the bottom of the sill 6. Therefore, the pebbles 11 and the like can be easily removed.

In the above embodiment, the inclined surfaces 6dx are provided on both side walls 6d of the guide groove 6a, but the present invention also allows the inclined surfaces to be provided on only one side wall of the guide groove. It is preferable that the width gradually widens from the top opening side, which is the entrance, to the bottom side. In the above embodiment, the sill 6 is provided with one guide groove 6a, but the present invention can also be applied to a sill provided with a plurality of guide grooves, such as two rows. Furthermore, although the above embodiments have been described with respect to the threshold of a landing, the present invention can be similarly applied to the threshold of a car.

[Effects of the Invention] As explained above, according to the present invention, the side walls of the guide groove provided in the sill are sloped to form the guide groove in a cross-sectional shape that is wider on the bottom side than on the top opening side. By doing this,
Even if a hard foreign object such as a pebble with a size similar to the width of the upper opening of the guide groove enters the guide groove, it will not be firmly caught between the side walls of the guide groove, and will be pushed by the guide piece when the door is opened and closed. It falls to the bottom of the guide groove. By making the width of the dirt hole provided at the bottom of the guide groove larger than the width of the opening of the guide groove, pebbles and the like that have fallen to the bottom as described above will fall through the dirt hole and below the sill. Therefore, it is possible to obtain an elevator sill device that can easily remove pebbles and the like.
