[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator display device that displays the position and driving direction of an elevator car, and particularly relates to an improvement of a display device using a printed wiring board.

[Conventional technology]

A conventional elevator display device will be explained with reference to the drawings. Figures 5 and 6 show display devices installed in elevator halls, respectively. Figure 5 shows the display device when there is one car, and Figure 6 shows the display device when two cars are installed side by side. be.

In the figure, reference numerals 1 and 11 indicate front plates, transparent display parts 2 and 12 made of synthetic resin, operation parts 3 and 13 on which a call registration button 20 is installed, and the display part 2 on the front side. , 12 and the operating parts 3, 13 are fitted into the recesses 4a, 14a, and the frame bodies 4, 14 have dovetail grooves 4b, 14b on the back side. 5 and 15 are printed wiring boards to which light sources 5a and 15a consisting of lamps and light emitting diodes and electronic components such as resistors are attached;
Light sources 5a, 15a are located at the bright parts 2a, 12a of
, and insert the foot of the bolt (not shown) whose head is inserted into the dovetail grooves 4b and 14b into the dovetail grooves 4b and 14b.
It is passed through elongated holes 5b and 15b perpendicular to 14b and fixed with nuts 21. 22 is a screw for fixing the surface plates 1, 11 to the brackets 6a, 16a of the outer boxes 6, 16, and 7, 17 are cables. Incidentally, the recesses 4a, 14a of the frames 4, 14 are cut out at least in the portions corresponding to the bright parts 2a, 12a. Although not shown, the surface plate 1,
The display parts 2 and 12 sides of 11 are also fixed to the outer boxes 6 and 16.

[Problem that the invention attempts to solve]

In the conventional device, completely different printed wiring boards 5 and 15 are required for one car and for two cars, and it takes a lot of time to design and manufacture them, especially in the case of three or more cars, which have a relatively small production quantity. , there was a problem that it required labor and cost. In addition, when aligning the bright parts 2a, 12a of the display parts 2, 12 with the light sources 5a, 15a of the printed wiring boards 5, 15, the printed wiring boards 5, 15 are vertically aligned along the dovetail grooves 4b, 14b. The printed wiring boards 5 and 15 are adjusted in the horizontal (short) direction by the elongated holes 5b and 15b, but unless the light sources 5a and 15a are energized, the light sources 5a and 15 are adjusted from the display parts 2 and 12 side. , 15a are not visible, making position adjustment very difficult.

The present invention aims to solve the above problems.

[Means to solve the problem]

In this invention, a base with a cutout window at a position corresponding to the bright area of the display part of the front board is attached to the back of the front board for each car, and furthermore, a print is printed on this base for each car. It has a wiring board attached.

[Effect]

According to the present invention, since the bright part of the top plate can be seen through the cutout window of the base, it is very easy to adjust the attachment position of the base to the top plate.
Since it is only necessary to attach the printed wiring board to the base, adjustment time can be reduced compared to conventional methods. In addition, since the base and printed wiring board are provided for each car, the same base and printed wiring board can be used for 2, 3, or more cars, which helps standardize products and reduce production time. Shortening and cost reduction can be achieved.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a display device installed in an elevator hall where two cars are arranged side by side, and is a diagram corresponding to FIG. 6. 30 is a surface plate, and side frames 31, 3 on both sides in the vertical direction
1. It consists of a locking part 32 at the upper center (left side in Figure 1), a display part 33 at the center, and an operation part 34 at the lower center (right side in Figure 1). A groove 31a into which the locking part 32, display part 33, and operation part 34 are inserted and fixed is provided on one side of the side frame 31, and a dovetail groove 31b is provided on the lower surface. 32a, 3
4a is a round hole, and the surface plate 30 is attached to the bracket 16a of the outer box 16 by screws 22 as in the conventional case.
It is for fixing to. Reference numeral 35 denotes a unit to which electronic components (not shown) such as a light emitting diode 35a and a resistor are attached, and one row is provided for each car. 36 is the above unit 3
5 to the surface plate 30, one row is provided for each car, and a cutout window is provided in the center at a position corresponding to the bright part 33a of the display part 33. 36a, and elongated holes 36b perpendicular to the dovetail grooves 31b of the side frame 31 are provided on both sides. The side of this side portion facing the adjacent bases has stepped portions 36c that engage with each other, and are integrated by being fitted into each other. Further, as shown in FIG. 2, a recess 36d consisting of a pair of opposing wedge-shaped protrusions is provided at a proper location in the center of the base 36.
On the other hand, the unit 35 is formed with an arrow-shaped protrusion 35b, and when the protrusion 35b is inserted into the recess 36d, the light emitting diode 35a and the window 3 are connected.
6a are made to match. Numeral 37 is a light source that illuminates the direction indicating section 33b of the luminous section 33a, and is provided in one row for each car.
They are connected by a spacer 38. Furthermore, elongated holes 37a and 38a are provided in the light source 37 and the spacer 38 in a direction perpendicular to the dovetail groove 31a of the side frame 31. Note that the detailed internal structure of the registration device of the call registration button 20 is omitted.

When assembling the display device of this embodiment, first, the locking part 32, display part 33, and operation part 34 are sandwiched between the side frames 31 by the grooves 31a from both sides, and then the dovetail groove 31
The leg of the bolt (not shown) whose head is inserted in b is inserted into the elongated hole 38a of the spacer 38 and the elongated hole 3 of the light source 37.
7a, and set the mounting position of the light source 37 to the dovetail groove 31.
a in the vertical (longitudinal) direction, and elongated holes 38a,
37a in the horizontal (horizontal) direction, the light source 3
7 to match the direction indicating portion 33b and tighten the nut. Next, the stepped portions 36 of the two bases 36, 36
c, 36c are interlocked to form two bases 36,3
6, and as in the case of the light source 37, attach the foot of the bolt whose head is inserted into the dovetail groove 31b to the base 36.
The window 36 is inserted into the elongated hole and adjusted so that the window 36 is aligned with the bright part 33a. Thereafter, as shown in FIG. 2, when the unit 35 is fixed by inserting the convex part 35b of the unit 35 into the concave part 36d of the base 36, the light emitting diode 35a, the window 36a and the bright part 33a are aligned. Furthermore, after installing the registration device for the call registration button 20 (not shown), screw 2
2, the display board 30 is fixed to the outer box 16 via the bracket 16a. As shown in FIG. 3, according to this embodiment, the bright portion 33a of the display board 30 can be seen through the window 36a of the base 36, so that the positions of the bright portion 33a and the window 36a can be easily adjusted.

In the embodiment shown in FIG. 1, a stepped portion 36c is formed on one opposing side of the base 36, and the other side is flat, but both sides may be provided with stepped portions. In this way, as shown in FIG. 4, even if there are three or more cars, it is only necessary to add bases 36, and the same units 35 need only be increased by the number of cars. Furthermore, even if the distance between the bright parts 33a, 33a of each car differs depending on the design of the surface plate, this can be easily accommodated by simply adjusting the overlapping margin of the stepped parts 36c.

[Effect of idea]

As explained above, according to the present invention, the same base and unit can be used regardless of the number of cars, so equipment can be standardized and productivity can be improved. Furthermore,
Since the top plate can be visually observed through the window in the base, the mounting position of the base and unit to the top plate can be adjusted extremely easily.
