Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation auxiliary device for a push boat switch, and particularly in a so-called multiple push boat switch in which a plurality of push boat switches are arranged side by side, when a - push boat switch is turned on, all other push boat switches are Each push switch is operated selectively by appropriately combining a two-point press prevention device that mechanically prevents the switch from being turned on and a self-holding device that mechanically holds each push switch in the closed position. The present invention relates to a proposal for a new operation assistance device for a push boat switch that enables the following.

Regarding this type of conventional multiple push button switch,
As seen in Publication No. 23745, the two-point press prevention mechanism and self-holding mechanism are each constructed separately and housed in the housing, making the configuration complex and therefore making this type of switch easy. This has led to an increase in the size of the casing.

This invention has been proposed in view of the above-mentioned points, and is configured so that a two-point push prevention mechanism and a self-holding mechanism can be installed easily and selectively from the outside of the housing in a small space. The present invention provides an operation auxiliary device for a push boat switch.

The present invention will be described in detail below based on Examples.
A is a multiple type in which multiple units are installed side by side on a mounting support frame P such as a panel.
This is a push button switch that can be closed, and its general structure is such that by pushing a push button member 2 which is constantly given upward tension by a return spring 1, an operating member 4 housed in a body 3 is lowered. 4 opens and closes a switch block 5 located at the bottom of the body 3.

In addition, the push switch A has a U-shaped recessed part 3a formed in a part of the body part 3 in relation to an operation assisting mechanism to be described later, and a protruding piece erected in the horizontal direction on the operating member 4. 6 protrudes from an opening 3b provided in a side wall of the recessed recess 3a into the recessed recess 3a, and as the operating member 4 moves up and down, the protruding piece 6 moves up and down within the recessed recess 3a. That's what I do.

Reference numeral 7 denotes an elongated guide member having a generally mouth-shaped cross section, and is configured to house a plurality of blocking pieces 8 therein so as to be movable within a certain range in the longitudinal direction.

The blocking piece 8 is movable between stoppers 9 attached to both ends of the guide member 7, and the total length of each blocking piece 8 is Ll, and the length between the stoppers is When L2 is L2, L2-L1=G. Therefore, each of the blocking pieces 8 is movable within the range of the gap G.

The gap G is the protruding piece 6 of the push switch A.
The diameter d of the blocking piece 8 is approximately equal to the diameter d of the blocking piece 8, and the upper end corner of the opposing end of the blocking piece 8 is formed as a slope 8a.

The guide member 7 containing the plurality of blocking pieces 8 as described above is fitted into the recessed notch 3a formed in the body 3 of each of the pusher switches A, but in this case, each of the pusher switches The switch A is positioned such that each protruding piece 6 faces the adjacent boundary between the two adjacent blocking pieces 88, and in a normal state, the protruding piece 6 is above the blocking piece 8. When the - pusher switch A is pressed, the protruding piece 6 of the pusher switch A is inserted between two opposing blocking pieces 88.

That is, when the - pusher switch A is pressed and the protruding piece 6 of this pusher switch A is inserted between the two blocking pieces 88 as described above, each blocking piece 8 is inserted into the guide member 7. There is no gap between the push switch A and the switch becomes fixed, and even if another push switch A is pressed, the protruding piece 6 of this push switch A comes into contact with the blocking piece 8 facing the lower part of the push switch A, preventing its lowering and therefore preventing operation. The lowering of the member 4 is prevented and the operating member 4 is prevented from opening and closing the switch block 5.

In other words, the blocking piece 8 is a plurality of pusher switches A.
If one of the push switches A is turned on, it functions as a so-called two-point press prevention function that prevents the other boat push switches A from being turned on.

In the above-mentioned guide member 7, a notch 71a is formed in the opposing portion of each blocking piece 8 of the force side wall 71 so as not to obstruct the vertical movement of the protruding piece 6 of the boat pushing switch A. It is a good idea to keep it.

Next, in the guide member 7, a plurality of holding pieces 10 movable in the longitudinal direction can be housed together with or instead of the blocking piece 8, and the holding pieces 10 are movable in the longitudinal direction. The piece 10 is a side plate 7 of the guide member 7.
Guide plate 11 slidable in the longitudinal direction along 2
The guide member 7 is fixedly fixed to the guide member 7 and housed in the guide member 7.

The holding piece 10, together with the guide plate 11, is always given elastic force in one direction by a spring 12, and its end is positioned opposite to the protruding piece 6 of the push switch A, and the upper end of the end The corner portion is a slope 10a, and a portion continuous with the slope 10a is provided with an engaging portion 10b that engages with the protrusion piece 6, and the operating member 4 is lowered by pressing the boat push switch A. In this case, the protruding piece 6 pushes the slope 10a of the holding piece 10 and moves the holding piece 10 in the longitudinal direction against the spring 12, while the protruding piece 6 descends. an engaging portion 10 in which the piece 6 is provided continuously on the slope 10a of the holding piece 10;
When the holding piece 10 reaches the position facing the protruding piece 6, the holding piece 10 is pushed by the spring 12, and the engaging portion 10b engages with the protruding piece 6.

That is, when the engaging portion 10b of the holding piece 10 and the protruding piece 6 are in the engaged state, the pusher switch A is activated by the return spring 1.
The upward extension of the pusher member 2 and the operating member 4 is prevented and maintained in a suppressed state.

The suppressed state of the pusher switch A as described above is the holding piece 10 or the guide plate 1 to which this holding piece 10 is fixed.
1 in the horizontal force direction against the spring 12, the engaging portion 10b of the protruding piece 6 and the holding piece 10 is
When the lock is released, the push switch A returns to its original state.

In this case, by pressing the pusher switch A corresponding to the other holding piece 10 fixed to the guide plate 11, the protruding piece 6 of this pusher switch A is moved to the slope 1 of the corresponding holding piece 10.
0a and the guide plate 11 together with this holding piece 10.
can be moved in the horizontal direction, and therefore the pusher switch A, which is already in the engaged state with the engaging portion 10b of the other holding piece 10, can be returned to its original state.

In this case, the pressed boat switch A has a corresponding holding piece 10
The protruding piece 6 is engaged with the engaging portion 10b of the holding portion 10b to maintain the suppressed state.

Although not shown, as a means for releasing the suppressed state of the pusher switch A as described above, a member having only the slope 10a instead of one of the holding pieces 10 on the guide plate 11 and not having the engaging portion IC1b is provided. may be fixed, and this member may be pushed by the protruding piece 6 of the corresponding pusher switch A to move the guide plate 11 and release the pusher switch A that is engaged with the other holding piece 10. Alternatively, the guide plate 11 may be moved horizontally by an electromagnetic device, thereby releasing the barge switch A which is in the suppressed state.

As mentioned above, the holding piece 10 functions as a mechanical self-holding device for the push switch A.

The blocking piece 8 and the holding piece 10 as described above can be stored in the guide member 7 and used individually or in combination depending on the desired operation mode of the boat push switch A.

In addition, in this invention, in order to prevent each of the blocking pieces 8 from separating from the guide member 7 in the guide member 7, a spacer 13 having a cross-section [shaped] is fixed to the guide plate 11. If the upper piece 13a prevents the blocking piece 8 from coming off upward, and at the same time the spacer 13 prevents the guide plate 11 and the blocking piece 8 from rattling within the guide member γ, a more practical effect can be achieved. It is possible to increase the

In the figure, reference numeral 14 denotes a guide member 7 which is attached to the recessed part 3a after fitting the blocking piece 8 or the holding piece 10 into the recessed part 3a of the body of the pusher switch A. This is a stopper member designed to prevent the device from coming off.

This invention can be achieved by simply fitting the guide member 7, in which the blocking piece 8 and the holding piece 10 are selectively combined and housed as described above, into the body recess 3a of a plurality of pusher switches A arranged side by side. Each pusher switch A can be associated with other pusher switches A to provide a desired operating mode such as a self-holding function or a two-point push prevention function, and the self-holding mechanism and two-point push prevention function can be installed from the outside in a recessed part in a small space. Since both mechanisms of the prevention mechanism can be selectively attached, the switch body can be downsized and manufactured easily. Moreover, the number of pusher switches A to be used can be arbitrary, and the number of guide members 7 can be reduced. Also, it is sufficient to prepare a long piece and cut it to the required length according to the number of pusher switches A to be used, and it can have an extremely large practical effect. .
