Description

[Detailed description of the invention] This invention relates to a control device for a gas combustion appliance or the like.

Generally, the Kotuku is opened and closed by rotating the Kotoku directly by rotating an operating knob fixed on the extension of the Kotuku shaft, but there are other operating means as shown in Figure 2. , there is one in which the reciprocating rotational movement of the operating lever 1' is transmitted to the lock shaft 5' via the intermediate lever 2'. In this case, since the intermediate lever 2' is used, even if the rotation range of the operating lever 1' is small, the cocking shaft 5' can be rotated largely.However, in the conventional example shown in FIG. The tip of the lever 1' is pivotally supported by a fixed support shaft 4', and a support shaft 6' is fixed near its base end, and the tip of the intermediate lever 2' is supported by fitting the support shaft 6' into the elongated hole 3'. Since the structure is such that the base end of the operating lever 1' is pivotally supported on the shaft 6',
During operation, the operating knob 7' fixed to the base end of the operating lever 1' protrudes forward from the guide surface (front wall of the device body) B' of the operating lever 1'. That is, since the base end operation knob 7' moves along a trajectory (see arrow a' in Fig. 2) with the distal end pivot portion (fixed support shaft 4') of the operation lever 1' as a fulcrum, it is The base end operation knob 7' of the operation lever 1' must be on the guide surface.
It protrudes in an arc shape from B', and protrudes only by b at its highest point, which not only makes it look unsightly, but also makes the guide surface the path of the knob when using the aperture amount of Kotoku V' as an intermediate position. Unless the operating knob is shaped into an arc to match, the operating knob will rise above the guide surface and its position cannot be clearly determined. In addition, if clothing or other objects get caught on the knob 7', the control lever 1' may be accidentally displaced during use, resulting in fluctuations in the amount of tightening. There is also a high risk of raw gas being released. Furthermore, since the intermediate lever 2' is pivotally supported on the proximal end side of the operating lever 1', there are many drawbacks in actual use, such as a lack of smooth operation.

This invention is proposed to correct the various drawbacks of the conventional art as described above, and one embodiment thereof will be described below based on the drawings.

In Fig. 1, reference numeral 1 denotes an operating lever with an operating knob 7 on the operating part at the base end, and a long hole 3 bored at approximately the middle position of the operating lever 1 is attached to a fixed support shaft 4 fixed to the body (not shown). When fitted, the operating lever 1 is pivoted so that it can freely move in the longitudinal direction within the range of the elongated hole 3 and can also freely rotate about the fixed support shaft 4 as a fulcrum. Reference numeral 2 denotes an intermediate lever, the base end of which is fixed to the shaft 5 of the Kotoku V, and the tip thereof fixed to a swinging support shaft 6, so that the tip of the operating lever 1 is pivotally supported by the swinging support shaft 6. ing. In this case, the arrangement of the swing support shaft 6 is such that the operating lever 1 is
The Kotuku and the Kotuku shaft 5 are arranged so as to be in the opposite direction to the fulcrum (fixed support shaft 4). That is,
The pot V is provided between the fixed support shaft 4 and the swing support shaft 6.

With the above structure, when the operating lever 1 is rotated by the operating knob 7 to open and close the pot V, the tip of the operating lever 1 swings as it rotates around the fixed support shaft 4. The pivot shaft 5 fixed to the base end thereof is rotated via the dynamic support shaft 6 and the intermediate lever 2. At this time, the swinging support shaft 6 rotates along the rotation radius of the intermediate lever 2 around the pivot shaft 5, while the operating lever 1 rotates around the fixed support shaft 4. , are pulled together with the elongated hole 3 by the intermediate lever 2 toward its distal end. Therefore, the operation knob 7 at the base end moves linearly while remaining substantially parallel to the guide surface B, and does not protrude beyond the guide surface B (see arrow a in FIG. 1).

According to Kotoku's operating device of this invention, the operating knob at the base end of the operating lever can slide in a straight line while maintaining approximately parallel to the guide surface on the front of the device, so the operating knob can be moved like a conventional device. The knobs do not protrude from the guide surface each time they are operated, the appearance is improved and it is easier to use, and unexpected accidents caused by protruding operation knobs are prevented, significantly increasing the product value. Since the intermediate lever is actuated at the tip of the control lever, it is more practical as it can be carried out more easily and smoothly than in the past, which operates from the proximal end of the control lever.
