Beverage dispensing apparatus lever arm assembly for a mechanical self closing beverage dispensing faucet
A beverage dispensing apparatus includes a faucet having a faucet body, a inlet and an outlet, and a faucet actuating portion. The faucet actuating portion includes a substantially flat body defining a lever portion aperture formed therein. The faucet body is at least partially interposed within the lever portion aperture. The actuating portion is selectively rotated about an axis for connecting the inlet in fluid communication with the outlet such that fluid flowing from the inlet to the outlet will flow through the lever portion aperture.
This application claims priority to U.S. Provisional Application 61/223,690 filed on Jul. 7, 2009, the entire disclosure of which is incorporated by reference.
TECHNICAL FIELDThe disclosure relates generally to dispensing liquids, and specifically to an apparatus and method for improving the dispensing of liquids.
BACKGROUNDTraditional beer tap faucets have been manually operated where a lever is required to be manually manipulated to open the faucet to provide a liquid flow and manually manipulated to stop the flow. Recent developments in beverage dispensing have provided a beer tap where a lever is required to be manually manipulated and biased in a direction to open the faucet to provide a liquid flow and when the lever is no longer biased in the direction, the flow will stop as the faucet closes. Generally, these faucets may incorporate a spring to close the faucet upon lever release. However, since the lever is above the faucet body and the outlet of the faucet is below the faucet body, operation of the faucet requires one hand to operate the lever and a second hand to hold the container that catches the liquid from the faucet.
What is needed is an apparatus for operating a beer tap faucet with a single hand. A favorable apparatus would permit a user to hold a container for catching liquid from the faucet while operating the faucet for both opening and closing of the faucet.
The drawings are illustrative embodiments. The drawings are not necessarily to scale and certain features may be removed, exaggerated, moved, or partially sectioned for clearer illustration. The embodiments illustrated herein are not intended to limit or restrict the claims.
An actuating lever is provided to improve the ease of dispensing a liquid.
DETAILED DESCRIPTIONAs illustrated, the shaft 50 includes a first end 70 and a second end 72. The first end 70 is defined by a generally cylindrical guide portion 74 having an actuating slot 76 formed therein. The second end is defined by a threaded disc connecting surface 78 formed on a shaft central member 80. The shaft central member 80 extends from the guide portion 74 to the threaded disc connecting surface 78. Further, a biasing portion connecting aperture 82 is formed in the first end 70 of the shaft 50. As best seen in the partially sectioned view of

The bonnet 54 includes a generally spherical inner surface portion 120, an inner threaded surface 122, and a lever aperture 124. The generally spherical fulcrum portion 106 is guided by the generally spherical inner surface portion 120 to permit rotation of the first shaft 52 relative to the faucet body 22, generally about the axis B-B (
The disc portion 56 includes a generally hemispherical disc mounting portion 130 and a disc 132. As best seen in
In the embodiment illustrated, the biasing portion 60 includes a connector 140, a first cap portion 142, a biasing member 144, and a second cap portion 146. The biasing member 144 is a helical spring, although other suitable biasing members may be used. The connector 140 is secured within the biasing portion connecting aperture 82 to permit the connector 140 to urge the shaft 50 in the direction S.
During operation of the faucet 20, the first lever 52 is rotated (as a user exerts a force) in the first rotational direction F generally about the axis B-B as the shaft 50 is guided toward the direction P relative to the faucet body 22. As the shaft 50 is guided toward the direction P relative to the faucet body 22, the disc 132 will lift from the faucet seat 30 to permit a liquid (not shown) to flow therebetween. Also as the shaft 50 is guided toward the direction P relative to the faucet body 22, the biasing member 144 is deflected such that the biasing member 144 will urge the shaft 50 toward the direction S.
When the user no longer exerts the force, the shaft 50 is urged in the direction S by the biasing portion 60 until the disc 132 contacts the faucet seat 30 as the first lever 52 is urged to rotate in the second rotational direction R from the open position OP to the closed position CP (
In the embodiment illustrated, the faucet 20 is a self-closing beer tap faucet, although other types of faucets may be used. Specifically, a conventional beer tap faucet may be used with the
The second lever 150 also includes a faucet mounting tab 156 attached to an upper portion 158, a lower portion 160, a first interconnecting member 162, and a second interconnecting member 164. The lever portion aperture 154 defines an inner edge 166 of the second lever 150. As will be apparent in the description of operation, the lower portion 160 may be deleted with the first interconnecting member 162 and the second interconnecting member 164 forming the bottom of the second lever 150.

The container guards 180, 180 are formed such that the first edge 196 and the second edge 198 are brought together as the central portion 204 is deformed. In one embodiment, the first edge 196 and the second edge 198 are in contact after the container guards 180, 180 are formed and prior to installation of the container guards 180, 180 on the second lever 150. During installation, the first edge 196 is moved away from the second edge 198 and the guard is placed on the edge 166, as illustrated. This installation method forms an interference fit that retains the container guards 180, 180 on the second lever 150 during use of the second lever 150.

With reference to
In the embodiment illustrated, the second lever 150 has dimensions where W1 is about 2 inches, W2 is about 1.188 inches, W3 is about 1 inch, H1 is about 5.636 inches, H2 is about 3.375 inches, H3 is about 1.011 inches, T is about, and α is about 80°. As illustrated, the lever portion aperture 154 width W2 is sufficient to permit the second lever 150 to rotate relative to the faucet body 22.
