Description

Switch with a switch body

Technical Field

The present invention relates to a switch for an operation display panel or the like of an elevator.

Background

In a switch used for an operation display panel of an elevator, a plurality of holes are formed in a lattice shape in a panel, and buttons are fitted into the holes. When the separate push button is fitted into each hole, the number of fitting steps increases, which disadvantageously increases the manufacturing cost of the switch. Therefore, conventionally, a method has been proposed in which: switches in which all the buttons are connected in a grid pattern are prepared in advance, and the buttons are fitted into the holes by attaching the switches to the panel (see, for example, patent document 1).

Problems to be solved by the invention

However, in the conventional switch described in patent document 1, all the push buttons are connected in a grid pattern, and therefore, the number of steps for fitting is reduced. However, even when the machining errors of the connecting portions between the adjacent buttons satisfy the tolerance, all the buttons may not be fitted into the holes due to the accumulation of the machining errors. In order to eliminate such a problem, the tolerance of each button must be made strict, which increases the manufacturing cost of the switch.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a switch that can reduce manufacturing costs.

Means for solving the problems

Effects of the invention

In the switch of the invention, the working hours of embedding the button into each hole are reduced, and the tolerance of the connecting part is not required to be too strict. This can provide a switch that can be manufactured at a reduced cost.

By inserting the male portion 33 into the female portion 32, the female portion 32 is fitted to the male portion 33. This allows the push button 12 having the male portion 33 to be easily connected to another push button 12 having the female portion 32. The male portion 33 may be fixed to the female portion 32 by an adhesive. Further, a male screw may be provided at the end of the male portion 33, and the male portion 33 may be fixed by a nut after passing through the female portion 32.

Fig. 5 is a schematic diagram showing a basic button column used in the switch 20 of fig. 1. Fig. 6 is a schematic diagram showing a reverse button column used in the switch 20 of fig. 1. The reverse button array AR shown in fig. 6 has the same button arrangement as the basic button array a shown in fig. 5, and is a button array obtained by rotating the basic button array a 180 degrees around the center point P of the basic button array a in the lateral direction shown by the arrow R in fig. 5.

The basic button row a has four buttons A1 to A4. The reverse button row AR has four buttons AR1 to AR4. The four buttons A1, A2, AR3, and AR4 are female buttons 51, respectively. The four buttons A3, A4, AR1, and AR2 are the push buttons with male and female portions 52, respectively.

The basic button row a is divided into a1 st button row portion 71 and a2 nd button row portion 72, with a plane S passing through a center point P of the basic button row a in the lateral direction indicated by an arrow R in fig. 5 and perpendicular to the lateral direction indicated by the arrow R in fig. 5 as a boundary. The 1 st link structure is provided on one end side of the basic button row a in the longitudinal direction indicated by the arrow T in fig. 5. The 1 st connecting structure has a1 st connecting part 81 provided to the 1 st button row portion 71 and a2 nd connecting part 82 provided to the 2 nd button row portion 72.

Further, the 2 nd connecting structure is provided on the other end side of the basic button row a in the longitudinal direction indicated by the arrow T in fig. 5. The 2 nd connection structure has: a1 st link 81 provided to the 1 st button row portion 71; and a non-connecting portion provided to the 2 nd button row portion 72 and having no 1 st connecting portion 81 and no 2 nd connecting portion 82. The 1 st connection part 81 can be connected to the 2 nd connection part 82. The 1 st connection part 81 and the 2 nd connection part 82 cannot be connected to the non-connection parts.

Fig. 7 is a schematic diagram showing a connection state of a button column in the switch 20 of fig. 1. The switch 20 is divided into a1 st button column group 61 and a2 nd button column group 62. The 1 st button array group 61 and the 2 nd button array group 62 are arranged in the vertical direction indicated by the arrow T in fig. 7. The 1 st button column group 61 is separated from the 2 nd button column group 62.

The 1 st button row group 61 and the 2 nd button row group 62 are the same button row group. The 1 st button column group 61 has a basic button column a and a reverse button column AR. The basic button array a and the reverse button array AR constituting the 1 st button array group 61 are arranged in the vertical direction indicated by the arrow T in fig. 7. In the vertical direction indicated by the arrow T in fig. 7, when the basic button row a and the reverse button row AR are arranged in this order, the basic button row a and the reverse button row AR are connected. That is, the two basic button rows a and the reversed button rows AR included in the 1 st button row group 61 are connected to each other in a state where the 1 st connection structure and the 2 nd connection structure are opposed to each other.

The 2 nd button column group 62 has two basic button columns a and a reverse button column AR. The basic button column a and the reverse button column AR are arranged in the longitudinal direction indicated by the arrow T in fig. 7 and connected to each other.

The button A1 of the basic button row a of the 1 st button row group 61 is opposed to the button AR1 of the reversed button row AR of the 1 st button row 61 in the vertical direction indicated by the arrow T in fig. 7. The push button A1 has a female portion 32 on the side of the push button AR1 facing thereto. The push button AR1 has a male portion 33 on the side of the push button A1 facing thereto. The female portion 32 of the button A1 is fitted to the male portion 33 of the button AR 1. The two button rows are connected by fitting a pair of buttons facing each other. Therefore, in the case of fitting each button into each hole, the number of fitting man-hours is not so large.

The female portion 32 of the button AR4 is fitted to the male portion 33 of the button A4. This enables the basic button array a to be connected more firmly to the reverse button array AR.

Between the respective buttons of the reverse button array AR of the 1 st button array group 61 and the respective buttons of the basic button array a of the 2 nd button array group 62 facing in the vertical direction indicated by the arrow T in fig. 7, there is no state in which the female portion 32 is provided on one side and the male portion 33 is provided on the other side. Therefore, the reverse button column AR of the 1 st button column group 61 is separated from the basic button column a of the 2 nd button column group 62. Therefore, in the vertical direction indicated by the arrow T in fig. 7, when the reverse button row AR and the basic button row a are arranged in this order, the reverse button row AR is separated from the basic button row a.

Two opposing button rows between the 1 st button row group 61 and the 2 nd button row group 62 are arranged so as not to be connected to each other in a state where the respective 2 nd connecting structures are opposed to each other. Thereby, the 1 st button row group 61 is separated from the 2 nd button row group 62. By providing separate portions between the button rows, it is possible to constitute button row groups, respectively. Therefore, the machining error of the button is not accumulated by the separated portions. Therefore, when the buttons are fitted into the respective holes, the tolerance of the connecting portion does not need to be made too strict.

The button array used in the switch 20 is composed of a basic button array a and a reverse button array AR. The reverse button column AR is a button column having the same button arrangement as the basic button column a. Therefore, the basic button row a and the reverse button row AR can be manufactured using a single button row mold. Therefore, the manufacturing cost of the button row is suppressed, and the manufacturing cost of the switch can be suppressed.

In fig. 5, in the basic button row a, the female buttons 51 are arranged at positions which are bilaterally symmetrical to the female buttons 52 with respect to a plane S which passes through a center point P of the basic button row a in the lateral direction indicated by an arrow R in fig. 5 and is perpendicular to the lateral direction indicated by the arrow R in fig. 5. Therefore, the position of the connectable button can be easily determined. Therefore, the button row can be easily designed. This can reduce the manufacturing cost of the switch.

The female portion 32 of the button A1 is disposed at a position rotationally symmetrical to the female portion 32 of the button A4 with the center point P of the basic button row a in the lateral direction indicated by the arrow R in fig. 5 as the rotational center. Therefore, even when the basic button row a is rotated 180 degrees around the lateral center point P of the basic button row a as the rotation center, the female portions 32 are arranged at the same positions in the button row. Therefore, the button row can be easily designed, and the manufacturing cost of the switch can be suppressed.

The switch according to embodiment 1 has a structure in which button array groups are connected and separated. As a result, a switch capable of suppressing the manufacturing cost can be provided.

The switch according to embodiment 1 has a structure for connecting and disconnecting the button rows. As a result, a switch capable of suppressing the manufacturing cost can be provided.

According to the switch of embodiment 1, the 1 st connection part and the 2 nd connection part are provided in the push button. As a result, the manufacturing cost of the switch can be reduced.

The switch according to embodiment 1 includes a plurality of the 1 st connection parts and the 2 nd connection parts, respectively. As a result, the button rows can be more firmly connected.

Fig. 8 is a schematic diagram showing a connection state of a button in the switch according to embodiment 2 of the present invention.

The switch 21 according to embodiment 2 of the present invention includes the 1 st button row group 61 and the 2 nd button row group 62. The 1 st button row group 61 and the 2 nd button row group 62 have three basic button rows a, and AR, respectively. By adopting such an arrangement, the 1 st button row group 61 and the 2 nd button row group 62 can be three button rows, respectively. The two basic button rows a included in the 1 st button row group 61 are connected to each other with the 1 st connecting structures facing each other. The two basic button rows a and the inverted button rows AR included in the 1 st button row group 61 are connected to each other in a state where the 1 st connection structure and the 2 nd connection structure are opposed to each other.

The switch according to embodiment 2 has a structure for connecting and disconnecting the button rows. As a result, a switch capable of suppressing the manufacturing cost can be provided.
