Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a door provided on a landing or a car in an elevator.

[Technical background of the invention]

Conventionally, this type of elevator equipment has a front panel 1 made of metal such as a thin-walled steel plate that has been subjected to a surface finishing process, and three layers arranged on the back side of the front panel 1, as shown in FIGS. 1 to 3. Metal reinforcing material 2 made of a drawn-out material etc.
．． It consists of 3.4. More specifically, the front panel 1 has bent portions 1a on both sides thereof having a U-shaped cross section and protruding toward the back side, extending to the lower end.

1a are bent and formed to face each other. On the other hand, the upper, middle and lower reinforcing members 2, 3.4 each have their inner plate parts 2g, 3a, 4m adhered to the front surface/back side of the P panel 1 with adhesive 5, and each outer plate part 2b, 3b,
Both ends of 4b are connected to the bent portions 1a on both sides of the motherboard 1 on the surface,
It is inserted into the inner side of Ih and fixed by boiling and welding to the folded edge portions lb and Ib of the bent portions 1a and 1a on both sides. In addition, the upper reinforcing member 2 is equipped with the arm of the door opening/closing drive mechanism (
A screw hole 6 is formed in the lower reinforcing member 4 to connect a door opening/closing guide piece (not shown).

[Problems with background technology]

By the way, when manufacturing the elevator equipment having the above-mentioned structure, both ends of each reinforcing material 2.3.4 are inserted into the bent portions 1a, Ia on both sides of the surface panel 1, so first the middle reinforcing material is Apply adhesive 5 to the inner plate part 3a of No. 3, and in that state, slide the middle reinforcing material 3 onto the front surface/back surface of the base panel 1 from its upper or lower end to a predetermined intermediate position and adhere it. After that, the upper reinforcing material 2 is inserted from the upper end, and the lower reinforcing material 4 is removed from the lower end of the inner plate portion 2a+.
With adhesive 5 applied to 48, it is necessary to slide it to a predetermined position above and below the front surface/back surface of gunnel 1 and adhere it. For this reason, when each reinforcing material 2.3.4 is slid, the adhesive 5 applied in advance may shift or peel off, making it impossible to maintain the required thickness and ensuring reliable adhesion. It was necessary to use a large amount of adhesive to prevent this.

Since quick-drying adhesives cannot be used to simultaneously slide the parts into place, it takes a lot of time to complete the adhesion and is inefficient. In addition, when fixing the reinforcing members 2, 3.4 in the upper, middle, and lower stages to the specified positions, the positional dimensions must be measured and positioned individually, and this positioning work is troublesome and requires a lot of effort. There were problems such as high costs, making it unsuitable for mass production, leading to high costs, and the drawback was that it was not easy to improve quality.

[Purpose of the invention]

This invention was made in view of the above circumstances, and it is possible to position and adhesively fix each reinforcing material to the surface/panel very easily and reliably, and with less labor and high efficiency, improving productivity and quality. Another object of the present invention is to provide highly practical elevator equipment that can reduce costs.

[Summary of the invention]

In the elevator equipment of the present invention, notches are provided in the folded edge portions of the bent portions on both sides of the surface panel, and both ends of the reinforcing material are fitted into the notches, so that the reinforcing material is attached to the surface A.
? This structure is such that it is adhesively fixed at a predetermined position on the back surface of the front panel, so there is no need to slide each reinforcing material to the back surface of the front panel during manufacturing as in the conventional method.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 4 to 7. In the figure, parts having the same configuration as those in FIGS. 1 to 3 are given the same reference numerals to simplify the explanation. Therefore, both back side bent portions 1a of the front panel 1,
Notches 8, 8 and 9.9 are formed at the opposing upper end position, intermediate position and lower end position of each folded edge 1b of Ia, 1b.
and 10.10 are formed respectively. In other words, notches 8, 8, 9° 9 and 10.10 are formed corresponding to the installation positions of the upper, middle and lower reinforcing members 2, 3, 4, respectively. The depths of these notches are the opposite notches 8, 8 and 9,
Each reinforcement member has a mutual spacing of 2° and 3.9° and 10.10°, respectively.
4, and the width of each notch is set equal to the width dimension of each reinforcing member 2.3.4. That is, the upper, middle, and lower reinforcement members 2° 3.4 can be inserted through the notches 8, 8, 9.9, and 10.10 on both sides without having to slide them into the front surface/back side of the panel 1 from the upper or lower ends. It is designed to fit in there by pushing it straight in from the rear. Furthermore, each of the two middle and lower reinforcement members 2°3.4 has the same cross-sectional shape as the conventional one (the upper reinforcement material 2 is abbreviated as Z-shaped,
(The middle reinforcing material 3 is hat-shaped, and the bottom reinforcing material 4 is crank-shaped.)
However, only the reinforcing material 3 in the middle is cut at both ends of the inner plate parts 3a, 3a, and has folded edge parts 1 on both sides.
b and Ib, and each width of the notches 9, 9 between the extensions is narrowed to be equal to the width of the outer plate portion 3b of the middle reinforcing member 3. Also, each reinforcing material 2.3.4 is attached to the surface A? through adhesive 5. When adhesively fixed to the back side of the panel 1, each outer plate part 2 b r J
The outer side of b r 4 b is dimensioned to be flush with the outer surface of the new curved portion 1 m on both sides and the folded edge portions 1 b and lb of 1 m.

In the elevator equipment having the above-described structure, when each reinforcing material 2.3.4 is attached to the back surface of the front panel 1, the inner plate portions 2a+, ? Apply the adhesive 5 to the required thickness on a+4m, and in that state insert both ends into the notches 8, 8, 9, 9, and 10. Push it in so that it fits. This completes the upper, middle and lower reinforcements 2. ．．
9.4 is directly positioned at predetermined positions at the top, middle, and bottom of the front surface and the back surface of the tunnel 1, without having to adjust the position by sliding as in the conventional case, and is then adhesively fixed with the adhesive 5.

Moreover, the outer plate portions 2b, 3b of each reinforcing member 2.3.4,
Both ends of 4b are held in a state where they are fitted into the respective notches 8, 8 and 9, 9 and 10° 10, thereby preventing vertical movement. In this state, both ends of the outer plate parts 2b, 3b, 4b of the upper, middle and lower reinforcing members 2, 3.4 and the edges of the notches 8.8, 9°9 and 10.10 are fixed by hot welding or the like. complete the assembly.

That is, in the structure described above, each of the upper, middle and lower reinforcement members 2.
3.4 can be directly adhesively fixed to each predetermined position on the back surface of the front panel 4 through the notch, eliminating the need for positioning adjustment by sliding and measuring dimensions as in the past, and also eliminating the waste of adhesive 5. In addition, it is possible to use a quick-drying adhesive 5, making it easy to manufacture, reducing time and cost, and improving quality.

Note that the present invention is not limited to the above-mentioned one; for example, the number of reinforcing materials is not limited to three at the top, middle, and bottom, but may be increased or decreased as appropriate, and the notches may be formed in accordance with the number. Bye.

Further, the form of the reinforcing material is shown in Figs. 8 to 10 as shown in 11.12.
13 may also be used, and in this case, cutouts 15 that match the shape of each reinforcing material 11, 12° 13 are also acceptable.
