Definitions

  • This invention relates to a tap for dispensing boiling or hot water or other hot liquid, particularly but not exclusively, for catering or other applications in which there is a risk of scalding the user.
  • Conventional hot water taps for example as used for filing teapots or other cooking vessels include an operating handle which may be raised to open the valve to dispense hot water.
  • Conventional catering taps have a hold open function in which the operating handle may be pulled forward to the holding position. This lifts the valve spindle against pressure of a spring raising the sealing member from the valve seat allowing water to pass through the tap. Once past the toggle position the tap is locked open. When the handle is then returned to the original position the spring urges the seal against the valve seat thus stopping the flow of water.
  • Such taps may include a self closing function which may be used when the operating handle is rotated through 180°. i this position the handle is pulled forward but does not pass the toggle position so that water is allowed to pass through the tap until the handle is released. Upon release of the handle the spring urges the seal into the valve seat closing the tap. This can be used for filling cups or other small vessels.
  • a problem may arise with use of conventional taps because inadvertent contact with the operating handle may open the valve allowing escape of boiling or hot water.
  • a catering tap comprises: an operating handle; a body containing an inlet, an outlet and a valve; the valve comprising a valve member cooperating with a valve seat, the valve member being moveable between open and close positions by movement of the operating handle; wherein the valve is biased towards the close position; the valve including a valve spindle extending through an aperture in a locking member to engage the operating handle; the valve spindle including one or more radially extending projections; the aperture of the locking member including one or more rebates corresponding to the radially extending projections and arranged so that the spindle and radially extending projections may pass through the locking member when the locking member is an unlocked position wherein the rebates and projections are aligned to open the valve; and wherein the handle and spindle can be rotated to a locked position in which the rebates and projections are not aligned thereby preventing opening of the valve.
  • the locking member may comprise a cap.
  • the handle may include one or more cam portions adapted to engage the surface of the cap to provide "hold open” and “self closing” functions.
  • the handle may be twistable between the locked and unlocked positions.
  • the spindle has two lugs or projections located at 180° on opposite sides of the cylindrical spindle, the cap having two rebates on opposite sides thereof. In this embodiment rotation through 90° locks the spindle into the cap so that the spindle cannot be withdrawn from the cap by actuation of the operating handle.
  • Figure 1 is a cross sectional view of a tap with the handle in the "self closing" position
  • Figure 2 is a cross section of the tap shown in Figure 1 with the valve opened
  • Figure 3 is a cross sectional view of the tap in the open position
  • Figure 4 is a cross sectional view from the front of the tap in the locked position
  • Figure 5 is a cross sectional view of the front of the tap in the unlocked open position
  • Figure 6 is a cross sectional view of the tap in the locked position
  • Figures 7-9 illustrate the rotation of the operating handle.
  • the tap shown in the Figures comprises a body (1) having an inlet (2) connected to a supply of boiling or heated water and a downwardly opening outlet (3).
  • the inlet and outlet have different orientations.
  • a resilient or elastomeric valve seal member (4) engages a valve seat (5) to close the valve.
  • a spring (14) shown in Figures (4) and (5) urges the seal member (4) downwardly into the enclosed position.
  • a spindle (6) extends upwardly through an aperture (9) in a locking member or cap (8).
  • the cap (8) is received on a threaded portion of the body.
  • an operating handle (10) is engaged to the upper part of the spindle (6) by means of an integrally moulded pin (not shown) received within a socket or aperture or hook (13) in the spindle use through an angle of 90°, 180° or 270°.
  • the base of the operating handle (10) has a rounded cam portion (11) and a flat face (12) on opposite sides thereof. As the handle is pulled forwardly in use as shown in Figure 2, engagement of the rounded surface
  • the spindle (6) carries (2) radially extending projections or lugs (7) disposed at an axle of 180° on opposite sides of the spindle.
  • the projections (7) are preferably elongated in the axial direction.
  • the aperture (9) in the cap (8) includes two rebates dimensioned to receive the projection (7) as the valve is opened when the cap is rotated to the unlocked position as shown in Figures 1, 2 and 3.
  • the valve may not be opened due to abutment of the upper end (15) of the projections (7) against the underside of the cap (8). hi this position the cap is locked so that the handle (10) cannot be accidentally depressed.
  • a pair of opposed lugs may be provided on the spindle.
  • Alternative configurations or projections of the spindle may be provided with a correspondingly shaped aperture in the cap to permit the valve to be opened in one or more selected positions.
  • a user twists the operating handle (10) to an unlocked position in which the aperture (9) and projection (7) are aligned.
  • the operating handle (10) may be pulled forwardly away from the inlet (2) to dispense a small amount of liquid, the valve automatically closing when the handle (10) is released.
  • the handle (10) maybe rotated through 180° as shown in Figure 3 so that the handle passes an over-centre toggle position allowing the valve to remain open when the handle (10) is released. This permits dispensing of a larger volume of liquid.
  • the handle (10) is returned to the upright position and the cap (8) rotated to lock the tap. Accidental operation of the tap and subsequent scalding is thereby prevented.
  • Figures 7 to 9 show the tap with the handle in various positions.
  • the handle is rotated to the "locked position”
  • Figure 8 the handle is rotatedto the "stay on” poisiton
  • Figure 9 the handle is in the "auto off position.

Abstract

L'invention concerne un robinet conçu pour la restauration comprenant : une poignée de manoeuvre (10) ; un corps (1) qui comporte une amenée (2), une évacuation (3) et une soupape. Cette soupape comprend un élément de soupape (4) qui coopère avec un siège de soupape (5), et qui (4) peut être déplacé entre une position ouverte et une position fermée par un mouvement de la poignée de manoeuvre (10), ladite soupape étant sollicitée vers la position fermée et comprenant en outre une tige de soupape (6) qui s'étend à travers une ouverture (9) ménagée dans un élément de verrouillage (8) pour venir au contact de la poignée de manoeuvre (10). La tige de soupape (6) comporte une ou plusieurs structures saillantes (7) s'étendant de manière radiale. L'ouverture (9) de l'élément de verrouillage (8) comprend une ou plusieurs entailles qui correspondent auxdites structures saillantes (7) et est configurée de manière que la tige de soupape (6) et les structures saillantes (7) puissent passer à travers l'élément de verrouillage (8) lorsque celui-ci (8) se trouve en position déverrouillée, les entailles et les structures saillantes (7) étant alignées pour ouvrir la soupape. En outre, la poignée de manoeuvre (10) et la tige de soupape (6) peuvent effectuer un mouvement de rotation vers une position verrouillée dans laquelle les entailles et les structures saillantes (7) ne sont pas alignées, ce qui empêche l'ouverture de la soupape.
