Description

  The present invention relates to a shank for attaching a beer cock to a beer server.

Currently, it is common in restaurants to install a beer server to facilitate the provision of beer to customers (see Patent Document 1).
A beer cock is attached to the front position of the beer server, and a beer is poured by placing a mug or the like against the mouth of the beer cock.
When the movable lever of this beer cock is pulled forward, beer is discharged, and when it is pushed deeply, only foam is discharged.
The beer cock is attached to the beer server via a beer cock attaching shank attached to the wall of the beer server.

By the way, the general structure of a general beer server is schematically described as follows.
Carbon dioxide in which beer cock and beer barrel filled with beer are connected by a beer passage tube or beer hose arranged in a refrigeration unit, and carbon dioxide gas for extruding beer from the beer barrel is enclosed The gas cylinder is connected by a gas hose.
When the beer cock is opened, carbon dioxide gas is fed from the carbon dioxide gas cylinder to the beer barrel at a high pressure, and beer is pushed out of the beer barrel by the gas pressure and discharged from the beer cock through the beer hose and the beer passage pipe. Is done.

By the way, there is a problem that the passage of beer tends to get dirty as a precaution in using the beer server.
That is, after the beer server is used, the beer adheres to and remains on the beer in contact with the beer such as the inner wall of the hose and the inner wall of the beer cock passage, and the yeast and bacteria are easily propagated from the remaining beer.
And if a beer server is used with the yeast etc. propagated, the propagated yeast etc. will mix in beer similarly, the taste of beer will worsen, and quality will fall.
Therefore, it is necessary to periodically clean the passage through which the beer passes.

In such a beer hose cleaning method, a beer barrel and a cleaning barrel filled with water are exchanged, and then the beer cock is opened to discharge water from the beer cock for a certain period of time.
Here, when cleaning the beer cock, the beer cock is first removed from the beer server, and after removing it, it is disassembled into parts and washed with water.
Thus, by regularly cleaning the parts to which beer adheres, it is possible to always provide high-quality beer.
In addition, daily cleaning is essential to keep the quality of beer at the highest level, which is extremely troublesome.
JP 2006-44690 A

However, if you try to clean the beer server every day, the beer remaining in the beer hose and the beer passage pipe is roughly equivalent to several beer mugs. It is extremely uneconomical.
Therefore, we tried to limit the deterioration of beer quality by performing cleaning only for beer cocks that easily get dirty. However, if the beer cock is simply removed, the beer cock is attached because the beer is pressurized from the beer barrel to the beer hose, the beer passage, and the beer cock due to the structure of the beer server, that is, carbon dioxide gas. Since the beer flows out from the mouth, it is necessary to quickly pour the attachment port of the shank for attaching the beer cock. However, even if carbon dioxide is shut off, beer leakage for a certain time is inevitable because the residual pressure of carbon dioxide exists in the beer hose and the beer passage pipe.

  The present invention has been developed to solve the above problems. That is, an object of the present invention is to provide a beer cock attaching shank in which a beer cock can be easily removed while the beer barrel is connected to a beer server.

The shank A for beer cock attachment of the present invention is fixed to the wall surface B1 of the beer server main body B.
The beer cock C is further detachably attached to the beer cock attaching shank A.
By operating the movable lever C2 of the beer cock, beer is discharged or only foam is discharged.
The beer cock mounting shank A will be described based on the following embodiment.

(First embodiment)
FIG. 1 is an explanatory view showing a state in which beer cock mounting shanks of this embodiment are arranged.
FIG. 2 is a cross-sectional view showing the beer mounting shank of this embodiment.
3 is a cross-sectional view showing the main body base of the present embodiment, where (A) is a plan view, (B) is a front view, and (C) is a cross-sectional view taken along the line CC in (A).
The beer cock attaching shank A mainly includes a hollow main body base 1, a hollow screwing sleeve 2 attached to the main body base 1, and a switching member for opening and closing a liquid flow path H1 formed in the main body base 1. 3.
The main body base 1 has a male screw part 11 at the rear part and a female screw part 12 at the front part, and a liquid flow path H1 is formed inside.
A pair of notches K are formed from the front end to the rear.

The main body base portion 1 is inserted into a mounting hole B11 formed in the wall portion B1 of the beer server main body B, and the nut N is screwed into the male screw portion 11, thereby being attached to the wall portion B1.
The screw sleeve 2 is attached to the main body base 1 by screwing. As shown in the cross section of FIG. 4, a male screw portion 21 is formed at the rear portion and a step portion 22 is formed at the outer periphery of the front portion.
Further, a funnel-shaped hollow portion is formed inside the screwing sleeve 2 to form a liquid flow path H2.
The male screw portion 21 at the rear portion of the screwing sleeve 2 is screwed into the female screw portion 12 at the front portion of the main body base portion 1 so that they are integrated with each other.
After the assembly of the main body base 1 and the screwing sleeve 2, the liquid flow path H <b> 2 of the screwing sleeve 2 communicates with the liquid flow path H <b> 1 of the main body base 1.

On the other hand, as shown in FIG. 5, the switching member 3 includes a closing portion 31 for closing the liquid flow path H <b> 1 and an opening portion 32 for opening the liquid flow path H <b> 1. A flow hole H3 is formed in the.
In addition, the switching member 3 has an enlarged portion 3A and an enlarged portion 3B at both ends. By providing the enlarged portion 3A and the enlarged portion 3B, in addition to the retaining function, a switching limit is defined as described later. , Switching can be performed reliably.
The enlarged portions 3A and 3B are formed by attaching block pieces, but may be formed integrally.

The switching member 3 is fitted into the notch K of the main body base 1, and the packing P <b> 1 is disposed on the main body base 1 in advance when fitted.
A cap nut D is extrapolated to the screwing sleeve 2, and the cap nut D is fitted to the step portion 22 to prevent the cap nut D from coming off.

The cap nut D connects the beer cock mounting shank A and the beer cock C (specifically, the screwing sleeve 2) and the beer cock C by screwing the cap nut D into the male screw portion C1 on the outer periphery of the beer cock C. The cock is brought close to the main body base 1 side and fastened and fixed.
At that time, an O-ring R is disposed between the beer cock C and the main body base 1, and the gap between the two is more reliably sealed.

  The shank A for attaching the beer cock has the above configuration. To attach it to the beer server main body B, first, the cover body E is passed through the main body base 1, and then the main body base 1 is inserted into the mounting hole B11 from the outside. Then, the nut N is screwed into the male screw portion 11 from the opposite inner side.

Since the cover body E fits into the step portion 22 formed on the outer periphery of the main body base 1, the wall portion B1 is fastened between the nut N and the cover body E, and the main body base 1 is fixed to the wall portion B1.
Thereafter, the packing P <b> 1 is disposed on the main body base 1, and the switching member 3 is fitted into the notch K of the main body base 1. And after fitting the switching member 3, another packing P2 is arrange | positioned.

After the packing P2 is disposed, the cap nut D is passed through the screwing sleeve 2, and the tip of the screwing sleeve 2 in the state where the cap nut D is passed through the female screw portion 12 formed in the main body base 1 is as described above. Screw firmly until it contacts the packing P2.
In addition, screwing of the screwing sleeve 2 is eliminated by screwing a screw pin into the pin hole 13 (not shown).
Thus, the switching member 3 is disposed between the bottom surface K1 of the notch K and the screw sleeve 2.
In this state, the switching member 3 can slide in a direction perpendicular to the main body base 1 to open and close the liquid flow path H1.

  As a result, the sealing state is maintained during use, even when the switching member 3 is moving or stopped. That is, liquid leakage from the liquid flow path H1 to the liquid flow path H2 in the closed state and liquid leakage from the liquid flow path H1 or the liquid flow path H2 to the outside are reliably prevented.

In this way, the switching member 3, the main body base 1, and the screwing sleeve 2 are assembled together.
After that, the beer cock C is attached to the beer cock attaching shank A, more specifically, to the screwing sleeve 2. However, the beer cock C is simple by screwing and tightening the cap nut D to the beer cock attaching shank A. Attached to.
Conversely, when removing, the cap nut D may be unscrewed.
Note that a key F is attached to the main body base 1 and the wall portion B1 of the beer server main body B in order to prevent the main body base 1 from rotating relative to the wall portion B1 as the cap nut D rotates.

Next, the opening / closing operation of the switching member 3 will be described.
Now, as shown in FIG. 6A, it is assumed that the switching member 3 is in an open state.
In this state, one enlarged portion 3A is in contact with the peripheral surface of the main body base 1, and the other enlarged portion 3B is separated from the peripheral surface.
The flow hole H3 of the switching member 3 communicates with the liquid flow path H1 and the liquid flow path H2.
That is, the liquid can flow from the liquid flow path H1 to the liquid flow path H2.

Then, as shown in FIG. 6B, the switching member 3 is operated with a finger and is slid until the other enlarged portion 3 </ b> B comes into contact with the peripheral surface of the main body base 1.
In this state, the flow hole H3 of the switching member 3 is disengaged from the position communicating with the liquid flow path H1 and the liquid flow path H2, and the closing portion 31 is located to block the liquid flow path.
In other words, the flow hole H3 formed in the opening part 32 of the switching member 3 leaves the liquid flow path H1 and the liquid flow path H2 and is sealed by the packings P1 and P2, and the closing part 31 is connected to the liquid flow path H1 and the liquid flow path H1. It moves between the liquid flow path H2 and the liquid flow path is closed.
In this state, the cap nut D can be unscrewed and the beer cock C can be removed and cleaned.

  Naturally, even if the beer cock C is removed, the liquid is stopped at the position of the beer cock mounting shank A, so the liquid in the beer server body does not flow out.

Next, a method for cleaning the beer cock will be described.
When cleaning the beer cock C, the switching member 3 is first slid to bring the beer cock mounting shank A from the open state to the closed state.
At this time, the enlarged portion 3B of the switching member 3 is reliably brought into contact with the peripheral surface of the main body base 1 so as to be completely closed.

  When closed, the cap nut D is unscrewed as described above, and the beer cock C is removed from the beer cock mounting shank A.

After removing the beer cock C from the beer cock mounting shank A, the beer cock C is disassembled and each part is washed with water.
When cleaning of the parts is completed, the moisture of each part is wiped and dried.
Finally, the beer cock C is assembled, the cap nut D is screwed into the male screw portion 11, and is attached to the mounting shank A by the same operation as described above.

Here, the example of 1 structure of the beer server provided with the shank A for beer cock attachment of this invention is shown.
FIG. 7 is an explanatory diagram illustrating a configuration example of a beer server.
As shown in the figure, the beer server X is for beer server main body B with the beer cock C attached to the front via the beer cock attachment shank A, the beer barrel T in which the beer is stored, and the beer for pumping the beer. Carbon dioxide gas cylinder G.
The beer server body B and the beer barrel T are connected via a beer hose L1, and the beer barrel T and the carbon dioxide gas cylinder G are connected via a gas hose L2.

The beer server main body B is filled with water or ice, and the beer is cooled by heat exchange between the water or ice and the beer passage pipe L3.
Here, a cooling pipe (not shown) is arranged in the beer server main body B, and a cooling medium kept at a low temperature circulates in the cooling pipe.
Heat exchange is performed between the cooling medium and water, and the temperature of the water is lowered to produce ice.
Then, the cooling medium deprived of heat from the water is once returned to a refrigerator (not shown) to be in a low temperature state, and then sent again into the cooling pipe.

  In addition, as a type different from the above-described beer server, a cold plate (not shown) is provided in the beer server body, and ice that is separately made in advance by an ice making machine is spread on the cold plate to cool the beer. There are also things.

The present invention has been described above by taking the embodiment as an example. However, the present invention is not limited to the above-described embodiment, and various modifications can be made.
For example, as long as the shape of the enlarged portion of the switching member described above has the same function, other shapes can be employed.
