Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a slide switch installation device having a simple structure, a small number of parts, and reliable operability.

[Prior art]

Conventionally, when incorporating this type of slide switch device into a keyboard, for example, if there are 12 tones, it would be easy to use a 12-button switch or a 12-position slide switch. Since it is a custom-made product, it is expensive,
In addition, it is troublesome in terms of maintenance, and there is also a problem in terms of space since they are unnecessarily stretched out in the direction of parallel installation. Therefore, as shown in FIG. 1(a), in addition to the six-button switches 18 to 1F, upper and lower row selector switches 2 are added, or the same figure (b) is used.
) As shown in 6-position slide switch 3A, 3
B is the upper row, lower row changeover switch 2 and discrimination, E,
It is used with the addition of D elements 4a and 4b.

However, since the switching stroke of the changeover switch 2 in FIG. 2A is slight, it is difficult to distinguish which tone is being produced. Furthermore, the Jiheshu switches 18 to 1F are structurally difficult to reduce in cost.

On the other hand, since two beam, E, and D elements are used in Figure (b), not only is the cost high and power consumption increases, but the installation and wiring work of the L, E, and D elements is also troublesome. . Also, in both methods, the top row.

In addition to requiring the changeover switch 2 in the lower row, if the selection switch must be operated after the changeover switch 2 is operated, the changeover operation cannot be completed in one go, making the operation complicated. Ta.

B.

It is located on a straight line connecting each interlocking member holding groove 25a to 25h of 22A, 22B, 23A, 23B, 24A, and 24B.

For example, when the slider 15e is slid from the neutral position upward in FIG.
a and engages with the engagement recess 44e, and this engagement locks the slider 15a in the slide position. At this time, the connection between the movable contact of the slider 15c and the fixed contact of the printed circuit board 11 is switched.

On the other hand, when the slider 15c is slid downward in FIG. 2 from the neutral position, the engagement protrusion 20e disengages from the engagement recess 44B and engages with the engagement recess 44b, locking the slider 15c in the slide position. . Also at this time, the connection between the movable contact of the slider 15c and the fixed contact of the printed circuit board 11 is switched. The engagement protrusion 20c and the engagement recess 4
4a, 44b or 44c, the association or separation is as follows:
This is made possible by the interlocking cam 13 moving from side to side in FIG. 2 against the return spring 18 as the slider 15e slides.

Note that the other sliders 15a, 15b, and 15dK are also switched in the same manner as the slider 15c described above.

C943a-43c, 44a ~44c, 45a ~4
On the long side side where 5c is provided, there are a pair of front and rear cam receivers 48a and 48b, 49m and 49b, and 50a and 5.
Qb, 51a and 51b are respectively provided in a protruding manner. These cam receiving parts 48a and 48b, 49a and 49
b, 50a and 50b, and 51a and 51b are located below the interlocking cam 13 and have slide holes 14a to 51b on the upper surface thereof.
By abutting the back surface of the peripheral edge of 14d, the interlocking cam 13 is held and its downward movement is restricted and prevented.

Sliders 15a to 15d are provided on the lower surface side of the interlocking cam 13.
An interlocking member 55 is provided. This interlocking member 55 is made of a bendable wire, thread, etc.
3, one end of which is latched to a pin 56 (see FIG. 2) hanging down on the back side of the case body 10, and the other end hanging down on the back side of the case body 10. It is locked to another provided bin 57 via a tension coil spring 58. The pair of pins 56 and 57 are connected to each of the holding parts 21A, 21B, 22A, 22B, 23A, 23B,
24A.

The connecting member 55 is provided so as to be located on an extension line connecting the interlocking member holding grooves 25a to 25h of 24B, and the intermediate portion of the connecting member 55 can freely slide into these grooves 25a to 25h and the grooves 3ia to 31d of each of the sliders 15a to 15d. has been retained. Therefore, for example, by sliding the slider 15c upward in FIG. 2, the engagement protrusion 20c and the engagement recess 44e
When the interlocking member 55 is locked in the sliding position by engagement with the slider 15c, the interlocking member 55 is pulled to the right against the tension coil spring 58 as the receiving portion 33c moves upward, and is positioned on both sides of the slider 15c. The portion X located between the pair of holding portions 23A and 23B is bent into a substantially inverted 7-shape, and this bent state is maintained until the slider 15c is returned to its original neutral position. Therefore, in such a state, that is, a state in which the slider 15e is at the switching position, any other slider, for example, the slider 15a, is moved upward (or downward) in FIG.
When the interlocking member 55 is slid to the slider 15a, the interlocking member 55
As the receiving part 30a moves upward (or downward), it is pulled to the right, so that the middle portions Y of the pair of holding parts 21A and 21B located on both sides of the slider 15a form a substantially V-shape as shown by the imaginary line. be bent. When the slider 15a is moved upward, the interlocking cam 13 is moved to the right against the return spring 18, so that the engagement recess 44C of the slider 15c and the engagement protrusion 20c are disengaged. Also, slider 15
When the portion Y of the interlocking member 55 begins to bend with the slide of a, the portion X bent in an inverted V shape is pulled and tries to return to a straight line. Therefore, slider 15
c is moved downward in FIG. 2 by the interlocking member 55, and when the engagement recess 44a corresponds to the engagement protrusion 20c, the interlocking cam 13
is restored by the force of the return spring 18, causing the engagement protrusion 20e to engage with the engagement recess 44e, whereby the slider 15
Lock c in neutral position. On the other hand, as the interlocking cam 13 returns, the slider 15a engages the engagement protrusion 20a into the engagement recess 42.
8, it is held in the upper position.

In other words, slider '15 set at the switching position
e is any other slider 15a, 15b or 15
Due to the movement of the interlocking cam 13 accompanying the sliding operation in step d, the interlocking cam 13 is released from the engagement protrusion 20e, and the slider 15 of the interlocking member 55 is moved.
When the portion X corresponding to e returns to a straight line under a tensile force, it is automatically returned to its original neutral position.

Note that the slider 15e placed at the switching position is replaced by the other slider 15a.

To return to neutral regardless of isb and isa, slide the slider 15e to neutral by hand.

Although the above embodiment shows an 8-position slide switch using four sliders 15a to 15d, the number of sliders can be increased or decreased as necessary.

5(a) and 5(b) show another embodiment of the present invention, in which a band-shaped plate spring 70 is used as the interlocking member in place of the interlocking member 55 made of wire, thread, etc. used in the above embodiment. This is what I used. In the figure, 71a.

71b and 72a, ? -2b is a leaf spring guide that slidably holds both ends of the leaf spring 70; 73.74 is a stopper that prevents the leaf spring 70 from coming off; the other configurations are the same as in the above embodiment, so they have the same reference numerals. The explanation will be omitted.

In this embodiment, the restoring force R of the leaf spring 70 is a force that prevents the return force R of the leaf spring 70 from returning from the quasi-stable state (when the switch is ON) to the stable state (when the switch is OFF).
When trying to turn on another switch, the restoring force R is smaller than AR (R<AR) (generated by the engagement of C and the engaging recess 44e), and the restoring force R is generated independently between each key. However, the engagement protrusion 20c begins to separate from the engagement recess 44c of the key that is already turned on, the blocking force AR decreases, and REAR' (however, AR'<AR) occurs just before the other switches are turned on.
This allows the leaf spring 70 to return.

Although the stoppers 71a, 71b, 72a, and 72b are provided to protrude from the back surface of the panel, they are not necessarily required. Further, the plate spring 70 may be provided independently for each switch.

6 to 9 are a bottom view of a main part, a sectional view of a main part, and a perspective view showing some constituent members, showing other embodiments of the present invention. For this example, Figures 2 to 4 are
An elongated cam plate 80 is used instead of the interlocking cam 13 shown in the figure, and the engagement recesses 4 of each slider 15a-15d are provided on the upper surface of the cam plate 80.

, 45a to 45c selectively engage engagement protrusions 81 to 45a to 45c.
The cam plate 80 is pressed against the back surface of the case body 10 by a spring 85, and biased to the left in FIG. I'm letting you touch me. Further, the case body 10
Five receiving members 90 are disposed on the back surface of the switch and are located between the switches and on the outside of the switches on both sides and slidably hold the intermediate portions of the interlocking members 55.

As shown in FIG. 8, this receiving member 90 has a long hole 92 which is formed into a substantially mouth shape and into which the cam plate 80 is inserted, and a groove 93 which is provided on the lower surface and into which the interlocking member 55 is inserted. A notch 94 is provided on a part of the side surface of the elongated hole 92 to allow insertion of the engaging protrusions 81 to 84 when inserting the cam plate 80.
is provided.

After insertion, the cam plate 80 is positioned in the hole portion 95 where the notch 94 is not formed. In addition, the interlocking member 5
5 is almost the same as the embodiment shown in FIGS. 2 to 4. Further, 97 is a spring receiving member.

It is obvious that even if the interlocking groove in such a configuration is used, the same effect as in the above embodiment can be obtained.

[Effects of the Invention]- As explained above, the slide switch device according to the present invention has at least two selection positions and one of the two selection positions of any switch among the plurality of switches arranged in parallel. When the switch is selected, an interlocking mechanism is provided in which the other switches are selected to a specific selection position, so the switching operation is simple and reliable. In addition, since the structure is simple, the number of parts is small, and a slider is used, the state of the switch can be easily determined without the need for identification glue, g, D elements, etc., and its effects are extremely effective. It is large.
