When the first valve 23b is pressed against the elastic force of the cylindrical coil spring 23d and moved downward in the drawing, the carbon dioxide gas passage is opened, and the second valve 23c resists the elastic force of the conical coil spring 23e. Then, when it is pushed downward in the drawing and moved, the beer passage opens. An engagement groove 23a, which will be described later, is formed in an annular shape on the outer peripheral portion of the base body 23f.

Next, the structure of the beer pouring device (beer dispenser head) will be described.

FIG. 2 is a schematic perspective view of a beer pouring device,
FIG. 3 is a vertical sectional view of the beer pouring device of FIG.

As shown in the drawings, a bottom cover 16 is attached to the upper cover 6 by a plurality of screws (not shown),
The device body is constituted by these two covers 6 and 16. The upper opening of the upper cover 6 is closed by a cap 7. Most of a resin-made main pipe 3 having a mounting portion 36 to be described later is inserted into the main body of the apparatus, and a middle portion of the main pipe 3 is pivotally supported by the main body of the apparatus so as to be tiltable. Hollow valve housing 26
Has an O-ring attached to one end and is inserted into the main pipe 3. A distribution pipe 26a as a pouring pipe is branched from a midway portion of the valve housing 26, and the distribution pipe 26a projects from an opening formed in the main pipe 3. Main pipe 3 narrowing section and valve housing 2
Inside the tip portion of 6, there is provided a tropide 5 having a tapered shape.

Most of the valve shaft 35 is the valve housing 2.
6, and a screw shaft 25 is integrally provided at the tip thereof. Since the screw shaft 25 is screwed onto the tropide 5, the tropide 5 is moved in the axial direction together with the valve shaft 35. Cylindrical coil spring 2 wound around the valve shaft 35
9 has one end locked to the flange portion of the valve shaft 35 and the other end pressed by the connecting member 2 screwed to the main pipe 3. The valve shaft 35 is urged inward of the valve housing 26 by the elastic force of the cylindrical coil spring 29, so that the beer passage between the outer peripheral surface of the tropide 5 and the inner peripheral surface of the main pipe 3 is urged. Is closed.

A pouring handle (dispensing handle) 1 is rotatably attached to a valve shaft 35 via a pin 30, and the pouring handle 1 is rotated in a direction indicated by an arrow in FIGS. 2 and 3. When it is tilted down, the valve shaft 35 moves leftward in FIG. 3 against the elastic force of the cylindrical coil spring 29, and the tropide 5 also moves leftward. As a result, the beer passage between the outer peripheral surface of the tropide 5 and the inner peripheral surface of the main pipe 3 is opened, and the distribution pipe 26a communicates with the mounting portion 36 via the beer passage.

The tip of the main pipe 3 has a beer barrel 37.
(See FIG. 4) is a mounting portion 36 to the base 23,
The mounting portion 36 includes a piston 9 fixed to the tip of the main pipe 3 as a check valve housing having a gasket 12, and a ball 1 provided in the piston 9.
3 and a thrust collar 38 having a gasket 14, which is fitted onto the piston 9 and the like.

The two eccentric cams 8a and 8b are provided on the upper cover 6.
Is rotatably supported by the eccentric cams 8a, 8b.
Both end portions of the mounting handle 4 are fixed to each. In addition, the mounting portion 36 described above includes two eccentric cams 8
It is supported by two brackets 31 which are vertically moved by a and 8b. When the mounting handle 4 is tilted toward the main body of the apparatus (states of FIGS. 2 and 3) or the opposite side (state of FIG. 6), the two eccentric cams 8
The a and 8b rotate, and both the main pipe 3 and the mounting portion 36 move downward or upward about the pivotal fulcrum of the main pipe 3.

The connecting portion 24 is a portion which is connected to the carbon dioxide gas discharge valve 28 (see FIG. 5) of the carbon dioxide gas cartridge 27 of the beer barrel 37 described above, and integrally includes the nozzle 22 which accommodates the balls 40. The valve 20 is provided on the bottom cover 16 so as to be movable in the axial direction. The valve 20 is biased inwardly of the bottom cover 16 by a cylindrical coil spring 21. A suspension arm 17 is connected to the rear end of the valve 20. The central portion of the suspension arm is suspended from one end of a pair of suspension levers 18, and the other end of the suspension lever 18 is supported by a spindle attached to the surface of the main pipe through a large hole in the elongated hole. . As a result, when the mounting handle 4 is tilted toward the main body of the apparatus, the lifting arm 17 extends due to the movement of the lifting lever 18 that descends together with the main pipe 3, and the valve 20 resists the elastic force of the cylindrical coil spring 21 and the bottom cover. It has a structure protruding from 16 and connected to the carbon dioxide gas discharge valve 28 of the barrel. The valve 20 is connected to the annular recess of the mounting portion 36 via the tube 19.

When the connection between the connection portion of the beer pouring device and the carbon dioxide gas discharge valve is deviated, even if the mounting handle is tilted down and the mounting portion of the beer pouring device is moved downward, If the interlocking connection part hits the periphery of the carbon dioxide gas exhaust valve and cannot project sufficiently, the hanging lever that projects the connection part cannot descend. Therefore, the excessive force that acts between the main pipe that moves downward and the lift lever that does not descend when the mounting handle is tilted is absorbed by the support shaft of the pipe that descends and escapes through the long hole of the lift lever. There is a safety mechanism in place.

Next, the operation of mounting the above-mentioned beer pouring device on a beer barrel will be described.

As shown in FIG. 6, first, the mounting handle 4 is tilted to the side opposite to the device main body side, the device main body of the beer pouring device 10 is held by the right hand, and as shown in FIG. The lower end of the piston 9 of the mounting portion 36 of the dispensing device is brought into contact with the second valve 23c of the mouthpiece 23 of the beer barrel, and the beer barrel 37 is placed at a predetermined position. In this state,
The two engagement arms 32a and 32b are drawn out of the annular portion 16a of the bottom cover 16.

Then, as shown in FIG. 8, while holding down the beer pouring device 10 strongly with the left hand (not shown), the mounting handle 4 is tilted toward the main body of the device as indicated by the arrow, and the nozzle 22 (see FIG. 3). ) Protrudes to open the carbon dioxide gas exhaust valve 28 (see FIGS. 5 and 6) and the mounting portion 36 (see FIG. 3).
Moves downward and sequentially presses the second valve 23c and the first valve 23b to open, and the two engaging arms 32a and 32b move from the position shown in FIG. It projects into the annular portion 16 a of the cover 16 and is engaged with the engagement groove 23 a of the mouthpiece 23. As a result, the carbon dioxide in the carbon dioxide cartridge 27 is pressure-fed into the beer barrel 37 via the carbon dioxide discharge valve 28, the nozzle 22 and the tube 19 (see FIG. 3), so that the beer in the beer barrel 37 is discharged. , The pressure feeding pipe 39 and the mounting portion 36, and is filled up to the tip of the tropide 5 (see FIG. 3).

Then, as shown in FIG. 3, when the pouring handle 1 is tilted as indicated by the arrow to move the tropide 5 leftward, the outer peripheral surface of the tropide 5 and the inner peripheral surface of the main pipe 3 are separated from each other. A beer passage is formed between them. Thereby, the beer in the beer barrel 37 is poured out into the predetermined cup 11 from the distribution pipe 26a by the action of the carbon dioxide gas described above.

[0019]

In the conventional beer pouring device described above, when the beer pouring device is mounted on the beer barrel, the beer pouring device is held by one hand and the lower end of the piston of the mounting portion is attached to the beer barrel base. While abutting against the second valve, the beer barrel must be placed and pressed at a predetermined position while the other hand must be operated to tilt the mounting handle. If the beer pouring device's mounting part is moved downward even if the mounting handle is tilted down, the positional relationship between the connection part of the beer pouring device and the carbon dioxide gas discharge valve of the carbon dioxide cartridge is not correct. The safety mechanism works without making the connection, so that the mounting handle can reach the fixed position, and only the mounting portion descends to move the second valve and the first valve.
Press the valves in sequence to open them.

For this reason, the operator judges that the pouring device is completely attached to the barrel, and the connection between the pouring device and the carbon dioxide gas exhaust valve of the beer barrel is incomplete despite the fact that the connection is incomplete. The beer leaks from the mounting part to start the pouring operation, the beer in the barrel cannot be poured out, and the operator is given a useless distrust or frustration without understanding the cause. There was a problem.

The object of the present invention was made in view of the above problems of the prior art. In order to easily and surely attach the beer pouring device to the beer barrel, it is confirmed whether the beer is properly attached or not. It is to provide a beer pouring device that can do it.

[0022]

In order to achieve the above object, the present invention is to be mounted on the mouthpiece of a beer barrel provided with a mouthpiece having a valve opened by being pressed and a carbon dioxide gas cartridge with a discharge valve. In a beer pouring device for pouring out beer in the beer barrel by guiding carbon dioxide gas from the carbon dioxide cartridge into the beer barrel to act on beer in the barrel, the device main body,
A mounting handle having an end rotatably supported on the apparatus body, a connecting portion for connecting to a discharge valve of the carbon dioxide cartridge, and an engaging arm that is engageable with the base of the beer barrel A portion of the beer barrel, the mounting portion is moved downward to press and open the valve of the beer barrel, and the engagement arm is projected from the device main body. It is characterized in that it is configured to be engaged with the mouthpiece of a beer barrel and to project the connecting portion so as to be connected to the carbon dioxide gas discharge valve and to display the projecting state.

Further, it is characterized in that the member for projecting the connecting portion in association with the mounting handle is provided with a mark so that it can be visually recognized from the outside of the apparatus main body.

[0024]

According to the structure of the present invention, even if the beer pouring device is intended to be placed at a predetermined position on the beer barrel, the connection between the beer pouring device and the carbon dioxide gas exhaust valve of the carbon dioxide cartridge is not properly positioned. , Even if the mounting part of the beer pouring device is moved downward by tilting down the mounting handle,
If the interlocking connecting part hits the periphery of the carbon dioxide gas exhaust valve and cannot project sufficiently, the safety lever operates to prevent the connecting lever from projecting downward. In this way, the suspension lever may or may not move depending on whether the mounting is complete or not, so that the suitability of the connection state can be visually confirmed by the movement of the mark provided on the suspension lever.

[0025]

Next, a beer pouring apparatus according to an embodiment of the present invention will be described with reference to the drawings. The beer barrel to which the present embodiment is applied has the above-mentioned conventional structure, and therefore its description is omitted.
