DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a gas appliance A in which the apparatus according to the present invention is implemented. In the case of this appliance A, a gas container B is vertically set below a burner which is an operating section C. . This gas container B is a nozzle N called a valve nozzle.
Is a publicly known one that has a valve mechanism that protrudes at the upper end, and that the valve nozzle N opens when pressed and discharges gas. A flange portion F surrounding the valve nozzle N is provided at the portion, and the flange portion F projects outward in the radial direction with the valve nozzle N as the center.
In the present invention, this flange portion F is used as an engaging portion for holding the gas container B.

The holding device according to the present invention is provided on the main body side member 10 of the gas appliance. In the case of the example, the main body side member 10
Is an operating part base 13 provided with a mounting opening 11 for inserting the valve nozzle N downward, and a substrate 1 for mounting it.
4 and a holding frame 15 having an opening 16 through which the valve nozzle N can pass, which are assembled together by a set screw 17. Reference numeral 18 denotes a small opening, which is formed on the substrate 14 for inserting the mounting opening portion of the operating portion base portion 13 (see FIGS. 2, 5, and 8).

2 to 4 show a first example of the holding device according to the present invention. In the case of the first example, the holding portion 12 is made of a leaf spring member. In order to provide the holding portion 12 engageable with the flange portion F, the holding frame 15 is formed in an upwardly U-shape that is recessed downward by about the height required for the holding portion 12, and within the range of the height from the bottom thereof. Several rising pieces 19 that can be engaged with the lower side of the flange portion F of the gas container B are provided. The rising piece 19 of the first example rises upward from the edge of the opening 16 of the holding frame 15 and projects inward from the opening 16 and is elastically engageable with the lower side of the flange F.
a (see FIG. 4).

A holding frame 15 having such a holding portion 12
Can be easily formed by pressing a sheet metal material. That is, when the material is press-molded, several rising pieces 19 (four in the illustrated case) are left in the opening 16 portion, and the rising pieces 19 that are elastically deformable are raised by bending the pieces. For this purpose, ordinary mild steel plate, stainless steel plate, etc. are suitable.

5 to 7 show a second holding device according to the present invention.
Here is an example: In the second example, as a holding means, one coil spring 20 is bent in a triangular shape and stretched around the edge of the opening 16 so that three holding portions 12 projecting into the opening 16 are formed. Is. The holding frame 15 in this case is also formed in a concave shape so as to accommodate the coil spring 20 so that it can be engaged with the flange portion F, and the locking pin 21 is provided at a position that divides the circular opening 16 at the bottom thereof into three equal parts in the circumferential direction. This planted, spring 20
Both ends of the spring hook 2 provided at the position where it hits the third pin position
It can be stopped by hanging on 2. The locking pin 21 is provided with a retainer by bending the upper end outward, for example.

In this case, the coil spring 20 is not one,
Two or three or more may be used. An example thereof is shown in FIGS. 8 to 10 as a third example of the holding device according to the present invention. In the case of the third example, in order to use the three coil springs 23,
Three sets of spring hooks 24 are provided on the holding frame 15 along the edge of the opening 16, and both ends of each coil spring 23 are hooked on each, and the central portions of the three springs 23 project into the opening to form the holding portion 12. It is something that is done. The spring hook 24 and the spring hook 22 of the second example can be formed when the holding frame 15 is press-formed.

In the holding device according to the present invention having such a structure, when the nozzle N of the gas container B is inserted into the mounting port 11 facing the lower surface of the gas appliance A, the nozzle N surrounds substantially the periphery of the nozzle N. The holding portion 12 is once retracted outward (elastically deformed) by the flange portion F of the gas container B provided, and enters into the upper side of the holding portion 12, and the holding portion 12 engages with the lower side of the flange portion F. Then, the elasticity keeps the nozzle N set in the mounting opening 11.

The gas container B receives the holding action of the holding device and the holding action of the holding mechanism 30 at the bottom of the gas container B at the same time. The holding mechanism 30 has a guide plate 31 that is hung from the main body side member 10 and that can contact the side surface of the gas container B, and a locking piece 32 that projects laterally from the lower end thereof. The spring mechanism presses the gas container to the upper mounting port 11. Therefore, by combining the holding device according to the present invention on the upper part, there is also an advantage that the load on the lower holding mechanism 30 is reduced.

In the above-mentioned embodiments, the gas appliance which is attached so that the gas container is suspended from the gas appliance with its nozzle facing upward has been described. However, the present invention is not limited to such a structure, and, for example, is not limited to this. It is also possible to implement a gas appliance in which the gas container is set sideways.

[0014]

Since the present invention is constructed and operates as described above, when the gas container is held, the unevenness based on the flange portion F is used for engagement to elastically hold the gas container. , Whether or not the gas container is attached is felt by the action at the time of engagement with the holding portion 12,
In addition, since the holding action of the nozzle portion of the gas container is ensured, a flexible wearing state is obtained in which there is no possibility of being detached even if it shakes a little after it is once attached, and when detached, it is resistant to the elastic holding force of the holding portion 12. Since it can be pulled by pulling, there is an effect that it is easy to handle.
