Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an operating device used for operating appliances, such as igniting gas appliances.

(Prior Art) In order to simplify operation, this type of device has two positions: an OFF position in which the operating member is returned by a spring, and an ON position in which the operating member is engaged with a locking member when the operating member is operated against the spring. At the same time, a device in which the engagement of the locking member is released by a release member is known.

(Problems to be solved by the invention) However, since such devices are easy to operate, mischief by children becomes a problem.

(Means for Solving the Problems) The present invention is aimed at solving the above problems, and has an OFF position that is returned to by a spring, and an ON operation that resists the spring to prevent the ball from impacting the locking member. An on-operation blocking member that snaps into engagement with the operating member in the off position is provided on the operating member that assumes the on position, and separate release mechanisms are provided for disengaging each engagement between the blocking member and the locking member. It is characterized by the provision of a member.

(Embodiment) An embodiment of the present invention will be described below based on the drawings. The figure shows an operating device for ignition operation in a gas stove. When operated, an on-off valve 6 provided in a gas passage 5 connected to a burner 4 is opened, and a switch 8 provided in an operating circuit of an igniter 7 is pressed. The on-position holding stepped portion 11 provided at the front part of the operation case is slidably inserted into the operation case 9 provided at the front part, and is supported by a return spring 10 interposed between the fixed plate 2 and the operation case 9. It is elastically locked to the front wall of 9 and returned to the OFF position, and a pressure blocking step 12 is provided at the intermediate portion thereof. Reference numeral 13 denotes a lock member, and 14 denotes an on-operation prevention member. These members 13 and 14 are vertically supported on the bottom wall of the operation housing 9 by a shaft 15 overlapping each other, and the on-operation prevention member 1 below the on-operation prevention member 1
4 is elasticated clockwise by a tension spring 19 so that a blocking claw 16 bent on its side surface snaps into contact with the stepped portion 12, and a pressing piece 17 protruding from the other side contacts the locking pin 18. Repelled locking member 13
The lock pawl 20 protruding from one side thereof is resiliently repelled counterclockwise by a torsion spring 21 so as to be resiliently landed on the stepped portion 11, and has a predetermined angle with the lock pawl 20 on the side thereof. It has a pressing piece 22 that protrudes. 23 indicates a second release member;
A first position where the pressing piece 17 is pressed against the spring 19 and a second position where the pressing piece 17 is released from the pressing position.
It is pivotally supported by the operation housing 9 via a shaft 24 so as to be able to swing freely between positions. Reference numeral 25 designates a first release member, which is slidably inserted into the operation housing 9 in parallel with the operation member 3, and is released by a return spring 26 fitted between it and the fixed plate 2. Step part 2 provided in the front part
7 is returned to the off position where it hits the front wall of the operation housing 9, and an abutting piece 28 is provided on the lower surface thereof to abut the pressing piece 22.

Next, to explain its operation, as shown in FIG. Since they are opposed to each other, the on operation of the operating member 3 is prevented, and then, as shown in FIG.
When the second release member 23 is swung to its first position as shown in FIG.
6 is disengaged, and then when the operating member 3 is turned on against the spring 10 as shown in FIG. The locking member 13 is held in the on position, and the locking member 13 is released by moving the first releasing member 25 to its contact piece 28.
is released when the locking member 13 is pressed against the pressing piece 22 of the locking member 13.

(Effects of the invention) As described above, according to the invention, the operating member has an OFF position in which it is returned by a spring, and an ON position in which it snaps into engagement with the locking member when the ON operation is performed against the spring. Since the on-operation blocking member that snaps into engagement with the member is provided, it is possible to prevent unnecessary on-operation caused by mischief of the operating member, etc., and the engagement of the blocking member is automatically performed with priority. Therefore, it is safe, and since it can be released by the second release member when the engagement of the blocking member is not required, it has the effect that it is easy to turn on the blocking member.

Claims (1)

[Scope of utility model registration request] An on-operation prevention member that snaps into engagement with the locking member in the off position is provided on the operating member that takes an off position in which it is returned by a spring and an on position in which it snaps into engagement with the locking member when it is turned on against the spring. An operating device characterized in that it is provided with separate release members for disengaging the blocking member and the locking member.
