Description

[Detailed description of the invention] Industrial application field The present invention relates to a switch device for various types of equipment.

BACKGROUND ART Conventionally, this type of switch device has a knob 3 that penetrates a switch 2 sliding on a main body 1 to lock the switch 2, and a knob 3 that locks the switch 2, as shown in FIG.
A spring 4 is provided that causes the switch to protrude from the upper surface of the switch 2. Furthermore, in order to give the switch 2 the feeling of turning on and off, a convex portion 7 is provided on the bottom surface of the switch 2.
and the main body 1 facing the convex portion 7.
A feel member 5 biased toward the switch 2 by a feel spring 6 was provided on the top surface of the switch.

With the above configuration, when the knob 3 is pushed against the spring 4, the switch 2 is unlocked and the switch 2 is
It can be turned on by sliding it, and at this time, when the convex portion 7 passes over the touch member 5, a feeling of being turned on can also be obtained.

Problems to be Solved by the Invention In such a conventional configuration, the knob 3 and spring 4 are used as a locking mechanism, and the protrusion 7 is used as a touch mechanism.
There were problems in that the number of parts was large due to the presence of a tactile member 5 and a spring 6, and that the mold for molding the main body was complicated and the price was high.

In addition, if the switch device has a load applied to switch 2 in the on direction, something may be placed on or dropped from the switch device, or the switch device may be placed in a bag and knob 3 may be pressed by mistake. There was a problem in that when the switch 2 was turned on, the load caused the switch 2 to move in the on direction and turn on.

The present invention is intended to solve these problems, and aims to reduce the number of parts, have a simple structure, be easily molded, and reduce the cost.

Furthermore, even when a load is applied to the switch in the on direction, the switch does not easily turn on even if the knob malfunctions, and can only be turned on by manual operation, which improves safety. The purpose is to

Means for solving the problem The lock part formed at the bottom of the knob is displaced in a direction away from the inner surface of the main body in response to the sliding movement of the switch, and is fitted into another adjacent hole. The part of the lock part that fits into the hole is made convex and sloped surfaces are formed on the front and rear sides thereof.

Function With this configuration, the switch can be operated with a finger in the on direction only when the top surface of the knob is pushed within the switch operation surface with a finger, and the touch member is constituted by a knob that operates separately from the switch. You will be able to do this.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 8 denotes a switch that slides on the upper surface of the main body 12 of various devices, and has a knob hole 9 penetrating it approximately in the center. A knob portion 16 of a knob 10 biased upward by a spring 11 from below is inserted into the knob hole 9, and the knob portion 16 of the knob 10 is inserted into the knob hole 9 so as to protrude above the switch operation surface 22 on the upper surface of the switch 8. The knob 10 has a lock portion 17 projecting from both sides of the knob portion 16, and an inclined lock surface 20 is provided at the end of the lock portion 17 in the on direction of the switch 8. On the other hand, the main body 12 is provided with a lock hole 15 into which the lock portion 17 of the knob 10 is inserted.

The switch 8 slides on the top surface 13 of the main body, and the lock portion 1 of the knob 10 slides on the bottom surface 14 of the main body.
The top of 7 is sliding. In other words, switch 8
The main body 12 is narrowed between the lock portion 17 and the lock portion 17.

Furthermore, when the switch is turned off, the knob 10 is turned by the spring 11.
The lock portion 17 enters the lock hole 15 and locks the movement of the switch 8, and the knob portion 16 protrudes from the upper surface of the switch operation surface 22.
When the upper surface 18 of the knob is pushed in until it is flush with the switch operation surface 22 or less, the lock hole 15 is configured to abut against the lock inclined surface of the lock portion 17.

Next, the operation of the above configuration will be explained.

When the switch is off, the knob 10 is urged upward by the spring 11, so the knob portion 16 protrudes from the knob hole 9 of the switch 8, and the lock portion 17 of the knob 10 enters the lock hole 15, so that the switch 8 is locked. .

Next, when the knob portion 16 is pushed in with a finger and the upper surface 18 of the knob becomes below the switch operation surface 22, the lock inclined surface 20 comes into contact with the lock hole 15. At this time, if you try to slide the switch 8 in the on direction, the lock slope 20 will lock into the lock hole 1.
5 and switch 8 slides on. Here, when the lock inclined surface 20 comes out of the lock hole 15, a turning-on feeling is also obtained.

As is clear from the above, when the top surface 22 of the knob 16 is flush with the switch operation surface 22, the switch 8 becomes slidable, so pressing the knob 16 with a soft finger turns it on. However, the switch 8 will not be able to slide just by hitting the knob 16 with an object, so the switch device is the only safety device that will prevent it from being turned on unexpectedly. Furthermore, since the locking mechanism also serves as a touch mechanism, the device is inexpensive and has a small number of parts.

Next, a case will be described in which an embodiment of the present invention is used in a catalytic combustion device.

In FIG. 4, the liquefied fuel 24 in the tank 23 is
is vaporized by the vaporizer 25 and passes through the nozzle 26,
It is combusted in the catalyst device 27 to heat the curler base 28. Here, a nozzle 26 is in contact with the switch 8. Nozzle 2 even when the product is not in use
Almost the same saturated vapor pressure is applied to the switch 6 by the liquefied fuel 24 in the tank 23 through the vaporizer 25, pushing the switch 8 in the on direction. To explain the operation in a switch configuration where the load is applied in the ON direction of the switch 8, when the top surface 18 of the knob is inserted into the switch 8 to the extent that it can be pushed in with a finger beyond the switch operation surface 22, it is locked into the lock hole 15. The structure is such that A<B, where the inclined surface 20 comes into contact with the switch, so that even if an object accidentally hits the switch 8 and the top surface 18 of the knob becomes flush with the switch operation surface 22, the lock surface 19 will not touch the lock hole 15.
switch 8 does not turn on. with your fingers,
The switch 8 is turned on only when the knob 10 is pushed in, the upper surface 18 of the knob enters from the switch operation surface 22, and the switch 8 is turned on.

As mentioned above, even if something is placed on or dropped from the switch 8, or if the knob 10 is accidentally pressed while it is in a bag, the top surface of the knob will only be pressed up to the switch operation surface 22 at the worst. The lock surface 19 is still in contact with the lock hole 15, and the switch 8 has a highly safe switch configuration that will not be accidentally turned on.

Effects of the Invention As described above, the present invention displaces the lock portion formed at the lower part of the knob in a direction away from the inner surface of the main body in response to the sliding movement of the switch, and fits into another adjacent hole. In addition, by making the portion of the lock portion that fits into the hole convex and forming slopes on the front and rear portions thereof, the touch member can be configured as a knob that responds to the sliding movement of the switch.

Therefore, no resistance is added to the operating load of the switch to cause a clicking sensation, and the sliding operation can be performed easily, and the locking portion of the knob can be moved in a direction different from that of the switch. As a result, stable on/off operation and a click feeling during operation can be obtained with a constant biasing force without being affected by variations in switch operation.
