Definitions

  • the invention concerns a dispenser head for dispensing liquids under pressure from a container, such as a keg of beer, and comprising a housing which may be detachably connected with the container valve, a spindle vertically slidable in the housing to active said valve, and an operating handle pivotally journalled on the housing to move the spindle, said operating handle being pivotable between a first position in which the valve is closed and a second position in which the valve is open and comprising a locking pin preferably slidable in the longitudinal direction of the handle and a spring or a similar means serving to press the locking pin toward the housing and to cause said pin to engage a locking groove in said housing when the handle is in its second position.
  • a dispenser head for dispensing liquids under pressure from a container, such as a keg of beer, and comprising a housing which may be detachably connected with the container valve, a spindle vertically slidable in the housing to active said valve, and an operating handle pivotally journalled on the housing to
  • FR-A-2386474 discloses such a dispenser head.
  • the operating handle In dispensing arrangements of this type the operating handle is in its second position subjected to the force from a strong spring, which is arranged in the valve and serves to close it when dispensing from the container is discontinued. This force is absorbed in the engagement between the locking pin and the locking groove, so that the handle remains in its second position and keeps the valve open.
  • the heretofore known dispenser heads have an operating handle with an outer axially slidable handle grip which is connected with the end of the locking pin.
  • the hand hereby follows a path which is directly at right angles to the path which the handle describes during closing, and this may cause an unexpected and unpleasant stroke in the hand when the engagement is released and the handle therefore suddenly snaps into its first position under the action of the strong spring. Further, when the handle grip is pulled outwardly, a slot will be formed between its innermost end and the handle in which the fingers may get caught when the hand grip is released.
  • the dispenser head of the invention is characterized in that the handle further comprises a hand grip which, in said second handle position, can move with respect to the handle in the same or approximately the same direction as the handle pivots when moving from its first to its second position, and that the hand grip is connected with the locking pin by connecting means arranged such that said relative pivoting movement between the hand grip and the handle is converted into such a great axial displacement of the locking pin away from the locking groove that the engagement of said locking pin with the locking groove is released.
  • the hand will thus logically follow the same path upon release of the locking engagement as the handle describes during closing from its second to its first position, or in other words, release of the locking engagement and closing of the handle takes place in one and the same continuous movement of the hand.
  • the hand grip may be pivotally journalled on the handle about a preferably horizontal axis. This provides for a particularly expedient mutual relative movement between the hand grip and the handle.
  • the connecting means between the hand grip and the locking pin may be a toggle mechanism preferably comprising a pivotable arm, and this pivotable arm may have its one end pivotally journalled in the hand grip about a preferably horizontal axis, which is disposed more closely to the housing than the outer end of the locking pin and suitable spaced from its axis at the locking pin side facing away from the first handle position, and the pivotable arm may have its other end connected with the locking pin by means of a pivotable link which is spaced more from the housing than the pivot axis of the pivotable arm.
  • the pivot link may conveniently consist of a cross member which is formed on the pivotable arm and which is supported by a breast member arranged at the end of the locking pin, said locking pin extending with clearance through an opening in the cross member. This results in a particularly simple and inexpensive structure and entails that much less force is to be used for releasing the locking engagement than known before.
  • the hand grip may be formed as a hollow jacket of plastics or metal disposed substantially around the movable parts of the release mechanism. This protects not only the movable parts of the release mechanism against damage because of outer influences, but also the operator's hand against getting injured or jammed by the mechanism.
  • Fig. 1 shows a dispenser head which is generally designated by 1 and which is detachably coupled with a valve 2 which is secured in a flange 3 on a container 4 having a top 5 and a bottom 6. The central portion of the container is not shown.
  • the dispenser head 1 comprises a housing 7, a spindle 8 which is slidable up and down in the housing 7, and an operating handle which is generally designated by 9 and which serves to move the spindle 8.
  • the handle 9 is pivotally journalled about pivots 10 on the housing 1 and can pivot between a first position which is the upper one in the shown embodiment, the handle being shown in broken lines, and a second position which is the lower one where the handle is shown in solid lines.
  • the container 4 is a keg of beer, and the dispenser head serves to dispense the beer from it.
  • the beer which is not shown, is under pressure from gaseous carbon dioxide which is fed through an inlet pipe stub 11 on the housing 1 from a cartridge or bottle (not shown).
  • the valve When the valve is open, as shown in fig. 1, the carbon dioxide flows, as indicated by the arrows, down into the container and urges the beer, as also indicated by the arrows, up through a down pipe 12 associated with the valve 2, through the hollow spindle 8 and further through a hose (not shown) to the position of use.
  • the valve 2 has a strong compression spring 13 to close the valve when no beer is to be dispensed.
  • the force from the compression spring 13 is transferred via a valve gasket 14 associated with the valve and the spindle 8 to the handle 9, which will therefore try to pivot to its first position.
  • the handle has a locking pin 15 which is pressed into a locking groove 16 in the housing 7 by a spring 17 when the handle is present in its second position.
  • valve When dispensing has been completed, the valve is closed again by moving the handle back to its first position, the locking engagement between the locking pin 15 and the locking groove 16 being released first.
  • This release takes place by means of a hand grip 18 which, in the embodiment shown, is pivotally journalled on the handle 9 about pivots 19, as shown best in figs. 2 and 3.
  • Figs. 2 and 3 show a preferred embodiment of the operating handle 9 where the connecting means consist of a specially arranged toggle mechanism.
  • This has a pivotable arm 20 which is pivotally journalled in the hand grip 18 about pivots 21, which are suitably spaced below the locking pin 15 and suitably spaced in a direction toward the housing 7 from the outermost end of the locking pin 15.
  • the pivotable arm 20 is fork-shaped with two flaps 22 which are pivotably journalled about their respective ones of the pivots 21 arranged on the inner side of the hand grip 18.
  • the two flaps 22 are interconnected at the other end by a cross member 23 which is supported by a breast member 24 provided on the end of the locking pin 15, which is passed through an opening 25 in the cross member 23 with a suitable clearance.
  • the hand grip 18 first pivots about the pivots 21 with respect to the handle 9 proper since this is kept locked in its second position by the engagement of the locking pin 15 with the locking groove 16.
  • This locking movement causes the pivots 21 of the pivotable arm 20 to be moved closer to the axis of the locking pin 15 and the cross member 23 of the pivotable arm to be pressed outwardly in the axial direction of the locking pin as it is kept in position around the locking pin by means of the opening 25. Since the cross member 23 engages the breast member 24, it simultaneously carries the locking pin 15 along so that the pin 15 will be disengaged from the locking groove 16.
  • the force required for this is much smaller than the spring force of the spring 17 and depends upon the angle formed by the flaps 22 of the pivotable arm with the locking pin.
  • the operating handle can therefore readily and conveniently be released from its locked second position and be moved into its first position by one and the same natural movement of the hand in the closing direction of the handle, and during this movement there is no risk of unintentionally damaging the release mechanism.
  • the first position of the handle is shown in broken lines in fig. 1.
  • an inclined face is provided over the locking groove 16, said face 26 extending inwardly toward the axis of the housing so that the locking pin extends up this inclined face 26 with its outermost end and thereby tensions the spring 17 when the handle is pressed down to its second position.
  • the valve can therefore be opened readily merely by pressing the handle downwards until the locking pin snaps into engagement with the locking groove.
  • the hand grip is formed as a hollow jacket 18 moulded from e.g. plastics or metal in two halves which are assembled around the handle e.g. by screws (not shown) so that the release mechanism of the handle is well protected against external damage.
  • the jacket 18 also protects the operator's hand against getting injured or jammed by the release mechanism.
