Description

[Detailed Description of the Invention] (Objective of the Invention) (Industrial Application Field) The present invention is provided on the front side of the floor of an elevator car to slidably guide the lower end of an opening/closing door at the entrance/exit of the car. Relating to threshold devices.

(Prior Art) Generally, an elevator car is as shown in Fig. 4.
A floor frame 3 is provided on the car receiving frame 1 via a vibration isolating rubber 2, a car floor 4 is provided on this floor frame 3, and a car main body 6 is further installed on the upper surface of the car via a booklet 5 to form a car chamber. This is the configuration provided. In addition, an entrance/exit lower is opened in the front part of the car body 6,
Further on the front side of the entrance/exit lower, a door 8 is provided, the upper end of which is not shown, suspended by a door hanger device so that it can be opened and closed. In order to slidably guide the lower end of the door 8, a sill 9 is attached to the front side of the car floor 4 so as to be long and horizontal, and is protected by hanging from the front edge of the lower surface of the sill 9. A junction box 11 is provided with a plate 10 and houses electrical system connections in a lower part of the sill 9.
is provided.

Further, the vicinity of the sill 9 of the car is shown enlarged in FIG. The threshold 9 is generally a single piece made of extruded aluminum, and has a guide groove 9a for slidingly guiding the lower end part 8a of the door 8 on the upper surface, and a mounting groove 9b on the lower surface.
The upper surface of the support member 14, which has an inverted plate-like cross section and is fixed to the front surface of the floor frame 3 with bolts 13, is tightened with a sill fixing bolt 15, and the upper surface of the sill 9 is fixed to the upper surface of the car floor 4. Floor panels such as tiles or carpets laid on top 4
It is made to be flush with a. Further, the protection plate 10
The threshold fixing bolt 15 is attached to the lower surface of the support member 14.
It is held via bolts 18, respectively, by an angled fixing bracket 16 fixed by a bracket 16 and a support bracket 17 protruding from the floor frame 3.

(Problems to be Solved by the Invention) Incidentally, this type of elevator is increasingly being used to transport cargo and move workers during the construction period of a building. During this construction period, the floors of the cars, the walls inside the cars, the left and right pillars of the entrances and exits, etc., will be covered with protective materials to protect them from damage. However, since the sill 9 is used to guide the opening and closing of the door 8, it cannot be protected and is damaged during loading and unloading operations. For this reason, many situations have arisen in which the sill 9 must be replaced with a new one and repaired upon completion of building construction.

In addition, there have been cases where the sill 9 has been similarly damaged and needs to be replaced during work such as transporting luggage for people moving from the inside of a building.

However, since the sill 9 is a single piece made of extruded aluminum as mentioned above, if it gets damaged, the entire sill 9 must be replaced with a new one, which is very uneconomical. Ta. In addition, the door 8 must be removed to replace the sill 9.
This was a very troublesome and time-consuming problem.

The present invention was developed in view of the above circumstances, and when a sill is damaged due to use of an elevator during construction and needs to be replaced, it is not necessary to remove the door etc. and replace the entire sill as in the past, but only partially. In other words, only the sill portion corresponding to the opening width of the car doorway can be replaced, making it extremely economical and extremely practical as it allows for the easy replacement and repair of damaged sills. The purpose is to provide.

[Structure of the invention]

(Means for Solving the Problem) In order to achieve the above object, the elevator car threshold device of the present invention is attached to the front side of the floor of the elevator car via a support member, and is installed at the lower end of the entrance/exit door of the car. A sill that is slidably guided is installed outside the frontage in such a way that it slides and guides the lower end of the door within the entire opening/closing stroke of the door, excluding a portion approximately corresponding to the width of the frontage of the car entrance/exit. A frontage [5!2] that is connected to the sill member and the frontage outer sill member and is removably attached to a sliding guide of the lower end of the door at a portion approximately corresponding to the width of the frontage of the entrance/exit of the car. It is characterized by being constructed as a divided structure consisting of an Ibe shrine and an Ibe shrine.

(Function) With the above configuration, the sill has a removable frontage width sill member disposed at a portion corresponding to the frontage width of the car entrance out of the entire length of the opening/closing movement stroke of the door, and a removable frontage width sill member disposed at the portion other than the frontage width. Since it has a divided structure consisting of a sill member, the area that will be damaged due to the ratio of luggage being carried into the car interior due to the use of elevators during the construction period is the frontage width sill located at the part corresponding to the frontage width of the car entrance. If the frontage outer sill member, which is only a member and therefore cannot be damaged, is left as is without removing it, and only the frontage width sill member is replaced with a new one, the damaged sill can be repaired, which is very economical. The replacement work for the opening width sill member is as follows:
This can be done very easily by opening the door so as to position it above the sill member outside the frontage, without having to go through the trouble of removing the door as in the past. become.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3. Components in the figure whose configurations overlap with those shown in FIGS. 4 and 5 are given the same reference numerals to simplify the explanation.

First of all, FIG. 1 is a plan view of an elevator car, in which a floor panel 4a such as tiles or a carpet is pasted over the entire surface of the upper surface of the car floor 4, and above it are the side walls of the car body 6 that constitute the car base. 6a and entrance/exit pillars 6b disposed on the left and right sides of the car entrance/exit lower. A sill 20 is horizontally provided on the front side of the car floor 4 of such an elevator at a height flush with the upper surface of the floor panel 4a, extending horizontally and extending in the left-right direction. The sill 20 is generally long enough to cover the entire length of the opening/closing movement stroke of the two-panel double-drawing entry/exit door 8, but it is divided into three parts: the middle and both ends. That is, out of the entire opening/closing movement stroke length of the door 8, it is divided into a frontage width sill member 21 whose length is approximately equivalent to the width of the frontage of the entrance/exit lower of the car, and frontage outer sill members 22° 22 on both ends thereof. It is considered a side street.

These frontage width sill members 21 and outside frontage sill members 22.22
As shown in FIGS. 2 and 3, there are guide grooves 21a, 22a, 22 on the upper surface that slidably guide the door lower end shoe portion 8a.
It has a. The frontage outer sill members 22 and 22 on both ends thereof are mounted fixedly on the upper surface of the main plate-shaped support member 14 with an inverted cross section, which is fixed to the front surface of the floor frame 3 as in the conventional case, with an interval corresponding to the width of the opening left and right from each other. and a frontage width sill member 2 is placed between them.
1 is placed on the upper surface of the support member 14. This frontage width sill member 21 has concave grooves 21b and 21c on the front and back portions of the lower surface, and by fitting these into the positioning bosses 23 provided on the upper surface of the support member 14, the frontage width outer sill member 21 on both ends can be closed. The member 21. is positioned in a state where it is in congruent connection with the member 21 without any deviation,
It also has stepped holes 21d that penetrate vertically at multiple locations spaced apart in the longitudinal direction, and each screw formed in the support member 14 by inserting a sill fixing screw 24 from above into each stepped hole 21b. It is fixedly supported by screwing into the hole 25. The upper opening of each stepped hole 21d is closed by a cap 26 that is elastically fitted.

The protection plate 10 disposed below the sill 20 of such a split structure is an angled fixing bracket 1 fixed to the lower surface of the support member 14 independently of the frontage width sill member 21.
6 and a support bracket 17 protruding from the floor frame 3 through bolts 18, respectively.

In addition, the frontage width sill member 21 can be replaced with a conventional aluminum extrusion material, and has a design that improves the design of the sill itself and allows for free color matching with the floor panel 4a such as tiles or carpet on the surface of the basket floor 4. The frontage outer sill members 22, 22 on both ends are almost invisible to passengers, and are therefore made of extruded aluminum as in the past. Note that this frontage outer sill member 22.degree. 22 may be made of the same hard resin molded product as the frontage width sill member 21.

Therefore, with the elevator car sill device having the above-described configuration, if the sill 20 that cannot be cured is damaged due to use of the elevator during the construction period and needs to be replaced, the sill 20 can be replaced by a sill member with an intermediate frontage width. 21 and frontage outer sill members 22 and 22 placed at both ends, the area that will be damaged by the amount of luggage carried into the car room due to the use of elevators during the construction period is as follows: Only the frontage width sill member 21 is arranged at the part corresponding to the frontage width of the car entrance/exit lower door, and therefore, the frontage outer sill member 22 and 22 which are not damaged are left as they are without being removed, and only the frontage width sill member 21 which has been damaged is left as is. If you replace it with a new one, you will be able to repair the damaged sill.

The damaged frontage width sill member 21 can be replaced by positioning the door 8 above the frontage outer sill member 22゜22 without having to go through the trouble of removing the door 8 etc. as in the past. In the open state, in this state, the frontage width sill member 2
The cap 26 is elastically fitted into each stepped hole 21d of 1.
using a screwdriver etc., then remove each sill fixing screw 2.
4 and remove it from the screw hole 25 of the support member 14. With this, the damaged frontage width sill member 21 is completely removed upwards, a new frontage width sill member 21 is fitted into the scar, and the cap 26 is fitted by positioning and fixing it on the support member 14 in the reverse order of the above procedure. This will easily complete the sill replacement and repair work.

In addition to the above-mentioned effect of being useful for replacing and repairing sills that have been damaged due to use of elevators during construction, etc., it is also convenient for replacing and repairing sills that have been damaged due to long-term use. When changing the design of a building or changing the floor panel 4a such as the tiles or carpet of the car floor 4, the frontage width sill member 2 is used in order to have a good color combination with it.
1 can be easily replaced with one of a different color.

〔Effect of the invention〕

Since the present invention is made as described above, when the sill is damaged and needs to be replaced due to the use of the elevator during the construction period, there is no need to remove the door etc. and replace the entire sill as in the past. Only the sill part corresponding to the entrance/exit opening can be replaced, making it very economical, and also making it extremely practical to replace and repair damaged sills, making it an extremely practical elevator car sill device. .
