Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for fastening a decorative panel having a decorative sheet adhered to the surface used for a side panel of an elevator cab.

(Prior art) Conventionally, the car compartments of Elm and Beta cars generally have a fifth
As shown in the figure, it is constructed by arranging a plurality of design panels (side plates) 1 and fastening them to each other.

The design of the panel body includes colored coating or printing on the surface of the panel body, vinyl chloride laminated on the surface of the panel body, or soft material on the surface of the metal panel body 2 as shown in Figure 6. There is a decorative sheet 3 attached thereto, and both have bent edges 1a on both ends bent in a gutter-like or angle-like shape on the back side.

As shown in Fig. 6, the fastening method for such a designed Bannert involves joining the mutually bent edges 1a and la, and inserting a plurality of fastening holes, which are fasteners, into the fastening holes, which are opposed to each other.
By inserting the bolt 5 into the bolt 5 and tightening the nut 7 through the washer 6 from the opposite side, the designed panel bolts were fastened to each other.

(Problem to be Solved by the Invention) By the way, in the conventional design panel fastening method described above, when bolts are tightened during fastening, surface pressure due to force is applied to the mutually bent edges 1a.
, la concentrates on the parts around the fastening. For this reason, in a design panel with a structure in which the decorative sheet 3 is attached to the surface, the decorative sheet 3 that is interposed between the bent edges la, la is partially subjected to strong pressure, Creep occurs as shown by reference numeral B in FIG. 7, and this creep stretches the portion of the decorative sheet 3 around the fastening, and as a result, the decorative sheet 3 is pushed out from between the folded edges 1a and 1a. As a result, a bulge C is generated on the surface side, which is visually unpleasant and spoils the exterior design of the interior of the car.

In addition, with the above-mentioned fastening method, the bent edges 1a and 1a have low rigidity because the only local fastening is performed between the bent edges 1a and 1a.

There was a problem in that the la was bent, causing a squeak in the car. Therefore, it is necessary to set the fastening points at small intervals and fasten them with a large number of fasteners, or to increase the rigidity by increasing the thickness of the panel body 2, which increases the number of man-hours for assembling the cab, increases weight, and increases costs. There was a problem that led to

The present invention was developed in view of the above circumstances, and it is possible to fasten the folded edges of design panels without applying a local concentrated load, and to eliminate the occurrence of swelling of the decorative sheet on the surface, as well as to prevent distortion of the panel. The purpose of the present invention is to provide an elevator design panel fastening method that can prevent the generation of squeaking noise.

[Structure of the invention]

(Means and effects for solving the problem) In order to achieve the above object, the elevator design panel fastening method of the present invention first involves superimposing a washer with a large area on the back side of the fastening portion of the folded edges of the design panels. The invention is characterized in that the design panels are fastened to each other by tightening the folded edges of the washers together with a fastener.

According to the above method, when the design panels are fastened together, the surface pressure due to the force is not concentrated directly on the bent edges of each other, but is spread widely through the washer having a large area, and is averaged. It becomes effective. As a result, the decorative sheet interposed between the folded edges is not subjected to local pressure, so that it does not bulge and swell toward the surface. Further, it is possible to secure mutual fastening of the design panels, and to prevent distortion of the design panels and squeaks in the cab.

Another elevator design panel fastening method is to remove the fastening area of the folded edge of the decorative sheet attached to the surface of the panel main body of the design panel, and then attach a thicker layer than the decorative sheet to the remaining part. It is characterized in that the design panels are fastened to each other by interposing a spacer and tightening the bent edges of each other together with the spacer using a fastener.

Even with this method, when the design panels are fastened to each other, the surface pressure due to the force is received by the spacer interposed between the mutually bent edges and does not act directly on the decorative sheet, so the front surface of the decorative sheet Almost the same effect as described above, such as the elimination of swelling, can be obtained.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2. Components in the figure that are the same as those shown in FIGS. 5 and 6 are given the same reference numerals to simplify the explanation.

Here, the design banelt...mutual folded edges 1a.

When fastening 1a with a bolt 4, a washer 5, and a nut 6, which are fasteners, the bent edge 1a of both.

An angular force plate-shaped washer 7.7 extending largely in the longitudinal direction is superimposed on the back surface of each fastening portion 1a. These washers 7,
Numeral 7 has an area several times larger than the washer 5, and has a somewhat elongated fastening hole 7a drilled in the center. With the large washers 7, 7 overlapped in this way, the bolt 4 of the fastener is inserted from the outside, and the nut 6 is tightened from the opposite side via the washer 5, thereby fastening the design panels 1.1 to each other.

Therefore, if the design panels 1 and 1 are fastened to each other as described above, the surface pressure caused by the force will not be concentrated and act directly on the bent edges 1a and 1a. , spread widely through the large-area washers 7, 7, and act on the average. As a result, the decorative sheet 3 interposed between the bent edges 1a and la is not subjected to local pressure force, so it does not swell up and swell toward the surface as in the past, and it looks and feels good when the basket is placed in the basket. The exterior design of the room can be improved.

Also, the design panel 1.1 has mutually bent edges 1a.

1a is sandwiched and reinforced by the large-area washer 7.7, which increases the rigidity and ensures strong fastening, making it possible to improve the design panel without narrowing the fastening interval P. Eliminates squeaks in distorted cages. In addition, by increasing the rigidity of the bent portions la, la, it becomes possible to reduce the thickness of the panel body 1, making it possible to reduce the weight of the cabin, reduce costs, and stabilize quality.

Next, another embodiment of the elevator design panel fastening method will be described with reference to FIGS. 3 and 4. Here again, the same reference numerals are given to the same components as those shown in FIGS. 1 and 2 to simplify the explanation.

Here, instead of using the large washer 7 as in the above invention, the decorative sheet 3 attached to the surface of the panel body 2 of the design panel 1 is cut around the fastening portions of the folded parts la and 1a between the design panels 1 and 1. Remove it by peeling it off or removing that part in advance.

Then, spacers 8, 8 each having a wall thickness t2 thicker than the wall thickness tl of the decorative sheet 3 are interposed in the removed traces.

Of course, a fastening hole 8a is also formed in the center of this spacer 8.8. Then, bend the spacers 8, 8 at the edge 1a,
a. Insert the bolt 4, which is a fastener, while interposed between them, and tighten the nut 6 from the opposite side via the washer 5 to fasten the design panels 1, 1 together.

Even with this method, when the design panels 1, 1 are fastened together, the surface pressure due to the force is received by the spacers 8, 8 interposed between the mutually bent edges 1a, 1a, and is directly applied to the decorative sheet 3. Since it does not work, it does not bulge and swell on the surface side as in the past, and it looks good and improves the exterior design of the interior of the car.

Also, the design panel 1.1 has mutually bent edges 1a.

Since the spacers 8, 8 are interposed between 1a in a superposed state, the spacers 8, 8 are reinforced, the rigidity is increased, and a stronger fastening than before can be secured, so that almost the same effects as the above method can be obtained. It becomes like this.

〔Effect of the invention〕

Since the present invention is made as described above, the folded edges of the design panels can be fastened together without applying a localized concentrated load, and the occurrence of swelling of the decorative sheet on the surface can be eliminated, making it visually appealing. The exterior design of the interior of the car can be improved. In addition, the folded edges of the design panels are reinforced, increasing their rigidity, ensuring strong connections, and eliminating distortion of the design panels and squeaks in the cab without narrowing the connection intervals, making it more economical. It is possible to improve quality and quality stability.
