Description

[Detailed Description of the Invention] The present invention relates to a sill installed in an elevator car or landing.

Conventionally, extruded aluminum is often used for elevator sills because it is easy to manufacture into any shape and has a good design effect.

However, because aluminum extrusion materials can only be manufactured with cut surfaces of the same shape, there have been cases in which customer requests cannot be met due to design issues. An example of this case will be explained with reference to the drawings.

FIG. 1 is a cross-sectional view of a two-door single-opening type entrance on the landing side, and FIG. 2 is an explanatory diagram of the entrance shown in FIG. 1 viewed from the landing side. In the figure, 1 is the high-speed side door, 2 is the low-speed side door, 3 is the threshold, 4 and 5 are the three-sided frames,
6 is the door stop rubber, 7 and 8 are the door guide grooves provided on the sill 3, 7 is the high speed side door 1, and 8 is the low speed side door 2.
This is to guide you through each. 9,9a
10 and 10a are guide shoes for the high-speed side door 1 and low-speed side door 2, respectively, and 11 and 12 are decorative grooves.

From a design point of view, this threshold has door 1 of threshold 3,
Guide grooves 7 and 8 are not provided in areas where doors 1 and 2 are not guided, and when doors 1 and 2 are closed,
Guide groove 8 is installed so that the guide groove is not visible from the landing side.
With the low-speed side door 2 closed (the state shown in Figure 1),
It is provided only up to a position that does not extend beyond the low-speed side door 2.

Therefore, it is not possible to use a sill made of extruded aluminum material whose cut surface has the same shape.
Guide grooves 7, 8, etc. had to be cut from a thick aluminum plate (20 to 25 mm).

In other words, when cutting from a thick aluminum plate, as shown in Fig. 3, the guide grooves 7 and 8 of the doors 1 and 2, the decorative grooves 11 and 12, and the sill 3 are fixed to the sill mounting member (not shown). It is necessary to machine the screw holes 13, etc. for the screw holes, resulting in poor workability and high cost.

Further, the above-mentioned problem occurs not only when two doors are opened on one side, but also when three doors are opened on one side, four doors are opened on one side, or four doors are opened in the center on both sides.

This invention was made in view of the above points,
Without cutting from a thick aluminum plate,
The purpose of this invention is to provide a threshold that has the same design effect as the conventional threshold described above.

An embodiment of the present invention will be described below with reference to FIG. 4 and FIG. 5, which is a sectional view taken along line AA of the sill in FIG.

In this embodiment, the sill 3 is made of extruded aluminum material,
Inserts 21 and 22 made of the same material as the threshold 3 are fitted into the parts that do not guide the doors 1 and 2. The inserts 21 and 22 may be fixed to the sill 3 by any method such as screws or adhesive. still,
The same reference numerals as in FIGS. 1 to 3 indicate the same parts.

With the above configuration, the same aluminum extrusion molding material as in the past can be used, so manufacturing is easy and inexpensive.

In addition, the insert body 2 fixed to the guide groove of the high-speed side door 1
2 can also be omitted. Further, although the above embodiments were concerned with landing sills, it goes without saying that the same method can be applied to car sills as well.

Also, recently, thresholds whose surfaces are made of stainless steel plates have appeared, but in this case as well, it is sufficient to simply insert an insert made of the same material (stainless steel) as described above.

As explained above, according to the present invention, even if the threshold is of a type that does not have a guide groove in the part where the door is not guided, aluminum extrusion shapes and stainless steel plates can be used in the same way as conventional thresholds, so mass production is possible. It is possible to provide an elevator sill with excellent performance and low cost.

[Brief explanation of the drawing]

Figure 1 is a cross-sectional view of a conventional entrance on the landing side with two doors that open on one side, Figure 2 is an explanatory diagram of the entrance in Figure 1 seen from the landing side, and Figure 3 is a sectional view of a conventional sill. FIG. 4 is a diagram showing an embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along line A-A of the threshold in FIG. 1...High-speed side door, 2...Low-speed gutter, 3...Sill, 4, 5...Three-sided frame, 7, 8...Guide groove, 2

Claims (1)

[Scope of Claim for Utility Model Registration] A car or a landing of an elevator having a high-speed side door and a low-speed side door, which has the same cross-sectional shape and has a guide groove on its upper surface for guiding the high-speed side door and the low-speed side door. An elevator sill, characterized in that, in the elongated sill, an insert made of the same material as the sill is fitted in a portion of the guide groove of the low-speed side door that does not guide the low-speed side door so as to be on the same plane.
