It is a container attachment and detachment device for gas appliances.

The safety member 15 is pushed and moved by a part of the gas container 50 when the gas container 50 is mounted. Therefore, the mounting of the container can be confirmed based on the positions before and after the movement, and the information that the gas container 50 has been mounted after the movement is transmitted to the related member, particularly the moving body 20. As a result, the moving body 20 can be moved. Therefore, the blocking member 1 is provided on the safety member 15.
6 are provided integrally to prevent the movement of the moving body 20 before the gas container 50 is mounted. The safety member 15 of the embodiment has a shaft shape that is movable in the mounting direction of the gas container 50,
The blocking body 16 has a brim shape having a diameter larger than the axis.

When the movable body 20 blocked by the blocking body 16 is movable by the removal of the blocking body 16, the movable body 20 is brought into a state in which it can be interlocked with the operation of the operating member 31 of the gas appliance A. The moving body 20 shown in the embodiment is a gas container 50.
The gas appliance A can be moved in a direction substantially orthogonal to the mounting direction of the gas appliance A.
The safety member 15 is attached to the moving body 20 so as to be movable in a direction substantially parallel to the mounting direction of the gas container 50.

The safety member 15 is urged by a spring means 17 acting against the mounting of the gas container 50. In the case of the embodiment, the brim-like blocker 16 hits the front end of the sliding bearing 18 on which the safety member 15 is slidably mounted and stops (see FIG. 2).
(B)) The movable body 20 is blocked by entering the lock groove 24. Further, a lateral groove 27 for allowing movement of the moving body 20 when the blocking body 16 comes off from the lock groove 24 is provided continuously with the lock groove 24.

The moving body 20 is provided with an interlocking means 21 which is brought into an interlocked state when it comes into contact with an interlock 32 provided on the operation member 31. Therefore, the interlocking means 21 is provided integrally with the moving body 20 at one end, and the other end extends in the direction of the operation member 31. In the case of the embodiment, the interlocking means 21 is the moving body 2
0 and an L-shaped protruding portion having an integral structure, and the raised side portion is notched and provided.

The illustrated interlocking means 21 has only a notched L-shaped rising edge. Therefore, in this structure, an elastic material such as a spring is used as a means 29 for returning the moving body 20 to its original position. Need. However, an engaging shape capable of interlocking with the movement of the interlock element 32 to the left or right can be provided on the rising side portion, and such an engaging structure can also be adopted as the returning means 29.

The movable body 20 can move in conjunction with the operation of the operating member 31, but at the position after the movement, it engages with the engagement partner 26 of the gas container 50 and makes the gas container 50 stable. An engagement receiving portion 25 is integrally provided. In the example,
The gas container 50 has an annular flange portion 51 provided at the front end portion on the mounting end side, and also has an annular end wall 52 formed with a slight gap behind the flange portion 51. The portion between the flange portion 51 and the end wall 52 is an engagement partner portion into which the first rising portion 22 provided with the engagement receiving portion 25 enters.

Therefore, when the nozzle valve 53 of the gas container 50 is connected to the mounting opening 42 of the gas appliance A, the safety member 15 is pushed by the flange 51 of the gas appliance A, and the blocking member 16 integral therewith.
Is disengaged from the moving body 20, and the gas container 50 is provided with a container holding device (for example, the magnetic holding means 35 of the embodiment or the gas container 5).
It is held in place by a mechanical holding means such as pushing the rear end of 0).

As a result, when the operating member 31 is operated, the movable body 20 is entrained in the operating direction, the engagement receiving portion 25 moves directly below the gas container 50, and the space between the flange portion 51 and the end wall 52 (26 ), The gas container 50 cannot be moved back and forth.

Further, according to the present invention, the gas container 50 is
An example in which the gas appliance A is individually mounted will be described. This gas appliance A has a storage chamber 54 in which two gas containers 50 are arranged side by side inside, and a front part of the storage chamber 54 has a storage chamber 54.
Communication tube 4 in a state where the pair of mounting ports 42, 42 are in communication with each other
1 is provided. The other end of the communication tube 41 communicates with a pressure reducer (or governor) 55 to adjust the pressure of the discharged gas. The gas is controlled to be opened and closed by operating the operation member 31, and flows from the pipe 56 to the combustion section 57.

A magnetic holding means 35 as a holding device for the gas container 50 is provided around each mounting port 42, and this is a magnet 3 provided on the outer periphery of a mounting member 43 having the mounting port 42.

Is provided, which engages with the alignment portion 54 in which a part of the flange 51 is cut away, and keeps the gas container 50 in a constant posture.

The moving plate 20 has two mounting ports 4 arranged in parallel.
It is arranged so as to lie on the lower body of 2, 42, and is attached movably in the left-right direction. Exemplary moving plate 20
Has a channel-shaped cross-sectional shape having first and second rising portions 22 and 23 at the front and rear, and two engagement receiving portions 25 are provided on the rear first rising portion 22 in a concave shape (FIG. 4). reference). The safety member 15 pushed by the flange portion 51 of each gas container 50 is installed in the sliding bearing 18 in a state of being urged rearward by the spring means 17 and is provided at a constant interval on the second rising portion 23 side. I have.

The sliding bearing 18 is integrally attached to the instrument body B inside the second rising portion 23 (see FIG. 2), and the moving body 20 moves in the left-right direction with respect to the instrument body B and the sliding bearing 18. It is possible. In the second rising portion 23 of the moving body 20, the lock grooves 2 are arranged at the parallel intervals of the gas container 50.
4 are formed at two places, and lateral grooves 27 connected to the lock grooves 24 are provided in the same direction (to the right in FIG. 4). Since the lateral groove 27 has such a size relation that the safety member 15 can be inserted when the blocking body 16 is disengaged from the lock groove 24, the lateral movement of the moving body 20 is allowed until it hits the inside of the lateral groove 27.

In order to link the movement of the moving body 20 with the operation of the operating member 31 of the embodiment comprising the knob of the gas appliance A,
An interlocking arm 28 as the interlocking means 21 is provided so as to protrude forward from the moving body 20. The side of the raised portion of the interlocking arm 28 can be brought into contact with the interlocking member 32 projecting from the operating member 31 as the interlocking means 21. The contact state is shown in FIG. 4, and the state after the moving body 20 has moved by the contact is shown in FIG.

In the container attaching / detaching device of such an embodiment, 2

0 is in a movable state. If only one gas container 50 is mounted, the safety member 15 on the non-mounted side will be
Since 6 is still in the lock groove 24, the moving body 2
0 does not become movable.

When the two gas containers 50 are properly mounted and the operation member 31 is rotated, the instrument plug 60 can be opened. The rotation of the operation member 31 causes the interlock 32 to rotate.
Slides the moving body 20 via the interlocking means 21, so that the adjacent portion of the engagement receiving portion 25 of the first rising portion 22 enters the gap between the flange portion 51 and the end wall 52 of the gas container 50 (Fig. 2, see FIGS. 4 and 5). Therefore, even if the gas container 50 is pulled backward, it cannot be removed because the flange portion 51 is caught on the first rising portion 22.

Generally, when using two gas containers, 1
If only one piece is attached and the gas appliance can be used, there is a risk that the gas container that does not emit gas will be overheated due to combustion heat and burst, but according to the present invention, the gas container 5
Unless two 0s are properly mounted, the operation member 31 cannot be operated to use the gas appliance, which is safe. Further, in the device of the present invention, even if there is a temperature difference between the two gas containers, the averaged pressure is applied to the safety device 65, and when the average pressure becomes abnormally high, the safety device 65 is activated to cause combustion. Stop.

Furthermore, since the gas container 20 does not come off after the operating member 31 is once operated and the moving body 20 moves, there is no problem that only one gas container 20 comes off. When the gas container 50 is not attached, the moving body 20 is blocked by the blocking body 16.
Since it cannot move, there is no risk of forgetting to open the valve as in the past and installing a gas container to cause gas leakage.

[0026]

Since the present invention is constructed and operates as described above, unless the gas container 50 is attached,
Since the operation member 31 cannot be operated, there is no risk of accidentally opening the gas passage, and gas leakage can be prevented. Further, when the container attaching / detaching device according to the present invention is applied to a gas appliance using two gas containers 50, the two gas containers 50, 50 are always used, so that one of them is referred to as overheating or rupture. There is no danger, and features such as equalizing the pressures of the two gas containers 50, 50 are exhibited.
