Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device which is mainly applied to the gas cooker's cooker shaft and which provides a click stop at the medium and low heat positions. Conventionally, this type of device has a rotary plate on a rotary shaft provided with a slit inclined in the radial direction, and a ball inside the slit that can be moved between an inner position and an outer position by being pushed by the slit. disposing each ball hole that engages with the rotational locus of the ball at the outer position at a first rotational position and a second rotational position of the rotational plate;
In this way, when the Kotoku shaft is rotated counterclockwise together with the rotary plate from the rest position to the high heat position, the next time it is rotated clockwise, it will be at the medium heat position, which is the first rotation position, and the second rotation position. There is a known type in which a click stop is given at the low heat position, which is the moving position, but in this case, when the click stop is once set to the low heat position and then rotated again in the direction of the high heat position, the ball will move inside. Since it moves to the opposite position, it does not engage with the ball hole at the medium heat position, and thus has the disadvantage that no click stop can be applied to it at the medium heat position. In other words, the medium heat position requires the click stop to be obtained only by first setting the click shaft to the high heat position and then returning it, which is inconvenient in that it is cumbersome to operate.

The purpose of the present invention is to obtain a device free of such inconveniences, and the rotary plate 1 has a slit 2 that is inclined with respect to the radial direction, and the slit 2 in the slit 2 is pushed to an inner position. A movable ball 3 is provided at the outer position, and the ball 3 at the outer position is provided.
The first rotation position and the second rotation position of the rotation plate 1 are located on the rotation locus of
In the type in which ball holes 4 and 5 are arranged to engage with each other at the rotating position, the rotating plate 1 has a second slit 6 inclined with respect to the radial direction, and a second slit 6 in the slit 6. A ball 7 is provided which can be moved freely between an inner position, an outer position and an intermediate position by being pushed by the user, and the first rotation position of the rotation plate 1 is provided on the rotation locus of the ball 7 at the intermediate position. The ball hole 8 that engages with this
It consists of:

The rotary plate 1 is fixed on a gas cock shaft 10 extending from a gas cock body 9 and rotates accordingly, and each ball 3, 7 is attached to an elastic plate 1 on the front side.
1, and each ball hole 4, 5, 8 is formed on the fixing plate 12 on the back side facing the ball hole 4, 5, 8.

To explain its operation, consider the case where the Kotoku shaft 10 is rotated together with the rotary plate 1 from the stop position shown in FIG. 2 in the counterclockwise direction in the drawing toward the high flame position.
As shown in the figure, the ball 3 is pushed inside the slit 2 and is in the inner position on the right side in the drawing, so that it does not engage with each ball hole 4, 5, and the ball 7 is pushed inside the slit 6 and is in the inner position on the right side in the drawing. When it is in the right inward position, there is no engagement with the ball hole 8, in other words, it changes from the stop position to the high fire position without a click stop. Next, consider the case where the shaft 10 is rotated clockwise from the high flame position, for example as shown in Figure 4, that is, the ball 3 is at the outer position on the left in the figure and rotates for the first time. position, i.e. in the medium heat position, the ball hole 4
and the ball hole 5 in the second rotating position, that is, the low heat position.
, thus creating a click stop at each position.

Next, if we consider the case where the heat is turned down to the low heat position and then the fire is turned open again, that is, rotated counterclockwise, the situation is as shown in Figure 5. In other words, at the medium heat position, the ball 3 is in the inner position on the right side in the drawing. Although it does not engage with hole 4,
In this case, the ball 7 is in the intermediate position and the ball hole 8
, and a click stop is applied to it.

In this way, according to the present invention, there is a second
The rotary plate 1 is provided with a slit 6 and a ball 7 inside the slit 6, and a ball hole 8 that engages with the slit 6 at the first rotation position on the rotation locus. In either case, the click stop can be obtained at the first rotational position, thereby eliminating the above-mentioned disadvantages of the conventional ones.
