Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating handle for an outdoor gas appliance, and particularly to a mounting structure for an operating handle of an operating device using a remote control wire device.

Conventionally, as shown in FIG. 1, this type of operation handle has an operation panel 3 screwed to a stay pipe 2 penetrating a wall 1, fixed to the wall by the stay pipe, and penetrating through the stay pipe. Furthermore, it is screwed to an operating shaft 4 that passes through the operating panel 3, and is rotatably mounted. For this purpose, a washer 5 is attached to a portion of the operating shaft 4 located on the back side of the operating panel 3, and the washer and the boss 7 of the operating handle 6 are connected to the collar portion 9 of the shaft hole 8 of the operating panel 3 through which the operating shaft is inserted. The operating handles are opposed to each other with the handles in between, allowing rotation of the operating handles at a fixed position. As a result, the operating shaft 4, which rotates together with the operating handle 6, engages and fits into the pulley device 10 fixed to the outer end of the stay pipe 2, and the pulley device is rotated by the operating handle.

In this case, the operation shaft 4 must be installed before the operation panel 3 is attached to the wall 1, or it must be inserted from the opposite side of the wall 1, and the operation shaft 4, operation panel 3, and operation handle 6 must be installed. It was very troublesome.

The present invention solves the above-mentioned conventional drawbacks and simplifies the installation and assembly of the operation part of a remote control wire device by making it possible to assemble the operation shaft and operation handle from the operation panel side after the operation panel is installed. The purpose is to

The basic configuration of the present invention is that the operating shaft is inserted into the boss of the operating handle so as to be swingable while engaging with the boss of the operating handle.
The boss is rotatably inserted into the shaft hole of the operation panel, and in this inserted state, the protrusion provided on the outer periphery of the tip of the boss is inserted from the notch of the collar that follows the recess. Make it protrude from the back side,
A washer interposed between the boss tip and the partition wall and fitted onto the operating shaft engages with a stopper of the operating shaft to prevent the operating shaft from coming off. This means that the operating range of the operating handle does not match.

With the above structure, the stopper part of the operating shaft is inserted into the boss of the operating handle with the washer fitted onto the operating shaft, and then the operating shaft is inserted into the shaft hole and the boss is inserted into the operating handle. When the protrusion is located on the back side of the flange of the shaft hole and the operating handle is positioned within the operating area, the operating handle is prevented from coming off by the engagement between the protrusion and the flange, and the operating shaft is provided at one end of the operating handle. The stopper is secured to the collar via a washer, and each of the above parts can be assembled with the operation panel attached.

Since the present invention has the above configuration, it has the following unique effects.

Since the operating shaft and the operating handle engage with each other so that they can swing freely, even if the stay pipe is not installed at right angles to the operating panel, that is, the axis of rotation of the operating handle does not match the axis of the operating shaft. Also allows for smooth rotational operation.

Hereinafter, embodiments of the present invention will be explained based on the drawings.

The structure of the main parts of the embodiment of the present invention will be described in more detail with reference to the exploded perspective view shown in FIG. There is a screw hole 11 on the surface side for
Recesses 12 for accommodating the bosses 7 of the operating handles 6 are arranged in series, and the outer periphery of the shaft hole forms a collar 9, with a notch 14 provided at the lower end of the collar.

The operating shaft 4 has a rectangular cross section to fit snugly with the shaft hole of the pulley device 10, and a pin 15 serving as a stopper is implanted at one end on the operating panel 3 side, and a washer 16 fitted onto the shaft is It is ring-shaped and its outer diameter is set larger than the shaft hole 8, and its inner diameter is set slightly larger than the outer diameter of the boss 7 of the operating handle 6. A pair of protruding tongue pieces 17, 17 are arranged to be close to opposing surfaces 18, 18 of the cross section of the operating shaft 4.

Next, at an appropriate position on the outer periphery of the tip of the boss 7 of the operating handle 6, as shown in FIG.
4 is provided with a protrusion 19 that can be inserted into the
Further, a recess 20 with an appropriate depth is formed in the center, and a pair of slits 2 are opened toward the tip of the boss.
1 and 21 are cut, and the width of these slits is determined by the wire diameter of the pin 15 and the tongue pieces 17 and 21 of the washer 16.
It is compatible with the width of 17. Further, an enlarged diameter portion 22 that matches the inner diameter of the concave portion 12 of the operation panel 3 is connected to the base of the boss 7, and the slit 21,
The lower bottom 23 of 21 extends further from the end face of the enlarged diameter portion, so that the protruding portions at both ends of the pin 15 implanted in the operating shaft 4 are accommodated below the end face of the enlarged diameter portion 22 with a margin. It's getting old.

To explain in more detail the case where the remote control wire device is attached to the wall surface 1 using the device of the above-described embodiment, the operation panel 3 and the pulley device 10 are connected to the wall surface 1 by the stay pipe 2 in the same manner as in the conventional case.
mounted on.

The pulley device 10 is fixed to a bracket 24 that is screwed to the stay pipe 2.
It is also possible to attach the subshaft 25 to the inserted state prior to attaching the operating handle 6.

To attach the operating handle 6 to the fixed operation panel 3, first fit the washer 16 onto the operating shaft 4, align the tongue pieces 17, 17 with the protruding part of the pin 15, and then remove the pin 15 and the tongue. Insert the pieces 17, 17 into the slits 21, 21 of the operating handle 6. The protrusion of the pin 15 is now housed in the enlarged diameter section 22 following the base of the boss 7, and the washer 16 is fitted onto the boss 7 and abuts against the end surface of the enlarged diameter section 22.
In this state, the operating shaft 4 is inserted into the shaft hole 8, the tip of the operating shaft 4 is inserted into the sub-shaft 25, the operating shaft 4 is further inserted, and the boss 7 of the operating handle 6 is inserted into the recessed part 1.
2, and the protrusion 19 of the boss 7 is passed through the notch 14 of the collar 9 to protrude to the back side of the collar. At this time, the operating handle 6 is in a position out of the operating range A due to the relationship between the protrusion and the notch 14. (FIG. 5) From this state, when the operating handle 6 is rotated to the initial position, the protrusion 19 will be located at a location away from the notch 14 on the back side of the collar 9, and the enlarged diameter portion 22 will be located in the recessed portion. 12, the washer 16 is located between the pin 15 and the collar 9, and the operating handle 6 and operating shaft 4 are both held in a non-removable state. In this state where the operating handle is attached, the protruding portion of the pin 15 is housed with a margin between the concave bottom 23 of the slits 21, 21 and the tongue pieces 17, 17 of the washer 16, so that the operating shaft 4 is attached to the operating handle 6. In contrast, it is placed in a state where it can swing and engages.

Next, when each part of the external pulley device 10 on the wall surface 1 is properly adjusted and fixed, the rotation of the operating handle 6 is controlled via the pulley device 10 and the other pulley device (not shown) on the instrument side. This will be transmitted to the operating section of the gas appliance. In this state of use, the protrusion 19 and the notch 14 do not match within the operating rotation range of the operating handle 6.
The operating handle 6 will not come off during operation.
