- the present invention relates to an apparatus for coupling fluid flow lines to a mobile sink unit or appliance. More particularly, but not exclusively, the invention concerns an apparatus for connecting water supply lines to a sink unit or a unit of catering or washing equipment. The present invention also relates to a mobile sink unit having a coupling apparatus for coupling fluid flow lines thereto.
- That apparatus includes a wall-mounted connection unit supporting a plurality of base connector elements that extend away from the wall. Those base connector elements may be coupled to satellite connector elements on the mobile unit simply by aligning the connectors and pushing the mobile unit towards the wall so that the connectors latch together with a horizontal coupling action.
- An operating handle provided on the mobile unit allows the connectors to be unlatched and separated.
- the apparatus described above has a number of disadvantages, some of which are as follows.
- the apparatus is relatively expensive and attaching it to a sink unit generally requires a rather expensive fabrication process. It is also quite large, occupying a large space at the back of the sink. Further, it has been found that the horizontal coupling action places a large stress on the wall and relatively weak walls such as partition walls therefore have to be strengthened when the apparatus is fitted.

- the first part of the apparatus may be attached easily to a standard sink unit without the need for special fabrication and the second part may be attached to a wall, usually without any need for reinforcement.
- the apparatus is relatively inexpensive and simple to operate.
- said second part includes a plate member for mounting the second part on a wall.
- the drive member may be separable from said first support member by relative movement in said first direction.
- the first connector elements are male connector elements and said second connector elements are female connector elements.
- the first support member may be biassed towards a position in which the first and second connector elements are disconnected.

- the first part 2 includes a pair of male connectors 6 that are connected by means of flexible hoses 8 to the taps or faucets of the sink.
- the male connectors 6 are mounted pointing downwards on a first support plate 10 with their longitudinal axes substantially vertical.
- the first support plate 10 is mounted by means of slide rods 12 on a frame 14 such that it can reciprocate vertically relative to the frame 14.
- Compression springs 16 are mounted on the slide rods 12 and are compressed between the lower face of the first support plate 10 and a lower part of the frame 14, so that they resiliently urge the plate upwards.
- the frame 14 is attached to a mounting plate 18 that is designed to be attached easily to the rear of a standard sink unit, for example using bolts (not shown).
- the second part 4 includes a pair of female connectors 20 that are connected by means of flexible hoses or rigid pipework (not shown) to hot and cold water supply ducts.
- the female connectors 20 are mounted on a second support plate 22 in the lower part of a rigid metal box 24 that is designed to be mounted on a wall, for example with screws (not shown) .

- an operating handle 30 that is connected to a shaft 32 having three radially extending cams 34,36.
- the central cam 34 engages the upper end of a central drive bar 38 that is connected to the link plate 28 for operating the sleeves 26. It should be noted that the central cam 34, the central drive bar 38, the link plate 28 and the sleeves 26 have been omitted from Figs. 2 to 4 for the sake of clarity.
- the central cam 34 extends downwards at an angle of approximately 45° below the horizontal. Rotating the handle 30 downwards through an angle of approximately 90° initially drives the link plate 28 downwards, thereby releasing the latching devices in the female connectors 20, and then allows the link plate 28 to return to its original position in which the latching devices are latched.
- the two outer cams 36 are identical to one another and are attached to the shaft 32 such that they extend upwards at an angle of approximately 45° above the horizontal when the operating handle 30 is in the raised position.

- the support plate 10 may thus be brought into engagement with the drive members 44 by pushing the sink unit together with the first part 2 horizontally towards the second part 4, as shown in Fig. 3.
- Rotating the handle 30 downwards through an angle of approximately 90° drives the support plate 10 downwards, thereby coupling the male and female connectors 6,20 to one another, as shown in Fig. 4.
- the link plate 28 is pressed downwards and then released, temporarily releasing the latching devices before latching the male and female connectors 6,20 together.
- the latching devices When the handle 30 is returned to the raised position, the latching devices are released by the action of the central cam 34 and the support plate 10 is simultaneously driven upwards, disconnecting the male and female connectors 6,20 from one another. A small amount of lost motion is provided between the handle 30 and the first support plate 10, to ensure that the latching devices are completely released before the support plate 10 starts moving upwards. Once the connectors have been disconnected, the first part 2 and the second part 4 may be separated from one another simply by pulling the sink unit away from the wall.
- the apparatus may optionally include a guide mechanism to assist with the correct alignment of the connectors as they are connected together.

Abstract
Description
- The present invention relates to an apparatus for coupling fluid flow lines to a mobile sink unit or appliance. More particularly, but not exclusively, the invention concerns an apparatus for connecting water supply lines to a sink unit or a unit of catering or washing equipment. The present invention also relates to a mobile sink unit having a coupling apparatus for coupling fluid flow lines thereto.
- Commercial catering establishments are subject to stringent health and hygiene requirements. Ease of access for cleaning purposes is a major consideration in the design of kitchens and catering equipment. It is increasingly common for such equipment to be mobile, thereby allowing staff full access to clean both the equipment itself and the underlying floor area. In the case of equipment such as sink units and dishwashers that have to be connected to a fresh water supply, it is desirable that the fluid flow lines should be readily disconnected when cleaning is required.
- An apparatus for coupling fluid flow lines to a mobile unit of catering equipment is described in the applicant's earlier British patent No. 2243422. That apparatus includes a wall-mounted connection unit supporting a plurality of base connector elements that extend away from the wall. Those base connector elements may be coupled to satellite connector elements on the mobile unit simply by aligning the connectors and pushing the mobile unit towards the wall so that the connectors latch together with a horizontal coupling action. An operating handle provided on the mobile unit allows the connectors to be unlatched and separated.
- The apparatus described above has a number of disadvantages, some of which are as follows. The apparatus is relatively expensive and attaching it to a sink unit generally requires a rather expensive fabrication process. It is also quite large, occupying a large space at the back of the sink. Further, it has been found that the horizontal coupling action places a large stress on the wall and relatively weak walls such as partition walls therefore have to be strengthened when the apparatus is fitted.
- Another device for operatively connecting fluid ducts to a portable utility unit is described in US Patent No. 3,623,166 in the name of Wilkinson. In that device, a water coupling connection is effected by driving projecting coupling nipples into engagement with sealing washers in respective coupling sockets. An operating handle is provided to effect the connection. The device is mounted in the floor and a vertical coupling action is employed, the axes of the coupling nipples being vertical and the two halves of the device being separable in the direction of those axes.
- It is an object of the present invention to provide an apparatus for coupling fluid flow lines to a mobile sink unit or appliance that mitigates at least some of the aforesaid disadvantages.
- According to the present invention there is provided an apparatus for coupling fluid flow lines to a mobile sink unit or appliance, the apparatus including a first part for mounting on the mobile sink unit or appliance and a second part for mounting on a wall, said first and second parts being separable by relative movement in a first direction that is substantially horizontal in use, said first part including a plurality of first connector elements mounted on a first support member, each first connector element having a longitudinal axis that is substantially perpendicular to said first direction and substantially vertical in use, said first support member being mounted for reciprocating movement in the direction of said longitudinal axes, said second part including a plurality of second connector elements mounted on a second support member, each second connector element having a longitudinal axis that is substantially perpendicular to said first direction and substantially vertical in use, each said second connector element being connectable to one of the first connector elements to make a fluid flow connection by axial movement relative thereto, a drive member for engaging the first support member when said first connector elements are axially aligned with said second connector elements, and an operating handle that is drivingly connected to said drive member, said operating handle being operable to drive said drive member in the direction of said longitudinal axes, to connect or disconnect said first and second connector elements.
- The apparatus allows a mobile sink unit or other appliance (such as a dishwasher or washing machine, for example) to be connected to and disconnected from a fresh water supply very easily, so allowing the unit to be moved for cleaning purposes. The first part of the apparatus may be attached easily to a standard sink unit without the need for special fabrication and the second part may be attached to a wall, usually without any need for reinforcement. The apparatus is relatively inexpensive and simple to operate.
- Advantageously said second part includes a plate member for mounting the second part on a wall.
- The drive member may be separable from said first support member by relative movement in said first direction.
- Advantageously, the first connector elements are male connector elements and said second connector elements are female connector elements.
- The first support member may be biassed towards a position in which the first and second connector elements are disconnected. The apparatus may include guide means for axially aligning said first and second connector elements. These features help to simplify the process of connecting and disconnecting the two connector elements.
- Advantageously, each said second connector element includes a latching device for releasably latching said second connector element to one of said first connector elements, said operating handle being drivingly connected to said latching devices and operable to release said latching devices. Preferably, the first and second connector elements comprise double shut-off couplings.
- According to a further aspect of the present invention there is provided a mobile sink unit having a coupling apparatus for coupling fluid flow lines thereto, the coupling apparatus including a plurality of connector elements mounted on a support member with their longitudinal axes substantially vertical, each said connector element being connected to a tap or faucet of the sink unit by means of a flexible connector and being suitable for separable connection to a complementary connector element through movement relative thereto in the direction of said longitudinal axis, said first support member being mounted for reciprocating movement in the direction of said longitudinal axes.

Thefemale connectors 20 are mounted substantially vertically with their open ends facing upwards. The male andfemale connectors - Each
female connector 20 includes a latching device (not shown in detail) for releasably latching the female connector to one of themale connectors 6. The latching device is operated by means of asleeve 26 provided on the exterior of theconnector 20 and may be released by pressing thesleeve 26 downwards. Thesleeves 26 are connected to alink plate 28 so that they may be operated in unison. - At the upper end of the

operating handle 30 is in the raised position as shown in Figs. 1 to 3, thecentral cam 34 extends downwards at an angle of approximately 45° below the horizontal. Rotating thehandle 30 downwards through an angle of approximately 90° initially drives thelink plate 28 downwards, thereby releasing the latching devices in thefemale connectors 20, and then allows thelink plate 28 to return to its original position in which the latching devices are latched. - The two
outer cams 36 are identical to one another and are attached to theshaft 32 such that they extend upwards at an angle of approximately 45° above the horizontal when theoperating handle 30 is in the raised position. Eachcam 36 is connected to avertical drive bar 40 by means of a pair ofhorizontal bars 42 that are located above and below theshaft 32. - At the lower end of each
drive bar 40 there is provided adrive member 44 comprising another pair ofhorizontal bars 46 that extend forwards from thevertical drive bar 40. The free ends of thebars 46 are bevelled away from one another. Thedrive members 44 are arranged to engage thesupport plate 10 of saidfirst part 2 when themale connectors 6 are aligned with thefemale connectors 20, as shown in Fig. 3. - When the
operating handle 30 is in the raised position as shown in Fig. 2, thedrive members 44 are raised by theouter cam elements 36, so that the gap between thehorizontal bars 46 is at the same height as thesupport plate 10. Thesupport plate 10 may thus be brought into engagement with thedrive members 44 by pushing the sink unit together with thefirst part 2 horizontally towards thesecond part 4, as shown in Fig. 3. - Rotating the
handle 30 downwards through an angle of approximately 90° drives thesupport plate 10 downwards, thereby coupling the male andfemale connectors link plate 28 is pressed downwards and then released, temporarily releasing the latching devices before latching the male andfemale connectors - When the
handle 30 is returned to the raised position, the latching devices are released by the action of thecentral cam 34 and thesupport plate 10 is simultaneously driven upwards, disconnecting the male andfemale connectors handle 30 and thefirst support plate 10, to ensure that the latching devices are completely released before thesupport plate 10 starts moving upwards. Once the connectors have been disconnected, thefirst part 2 and thesecond part 4 may be separated from one another simply by pulling the sink unit away from the wall. - The apparatus may optionally include a guide mechanism to assist with the correct alignment of the connectors as they are connected together. This guide mechanism may take the form of a pair of bevelled guide members (not shown) provided on either side of the wall-mounted
box 24, which engage the sides of theframe 14 and guide it into the correct position as the sink unit is pushed towards the wall. - The apparatus described above does not include a drain connector for waste water as in most situations where it is used the waste conduit of the sink unit will empty directly into a drainage gully provided in the floor. However, the apparatus may optionally include a drain connector, for example of the type described in the inventor's earlier British patent No. 2243422, or of the type shown in Fig. 5. The drain connector shown in Fig.5 includes a
drain tee 48 attached to the mobile sink unit. Attached to the outlet of thedrain tee 48 is a length of taper pipe 50. Adrain receiver 52, attached to the wall, is positioned such that it is directly in line with the taper pipe 50. The taper pipe 50 connects and disconnects easily with thereceiver 52 as the mobile sink unit is connected or disconnected from the wall mountedsecond part 4. - According to the second embodiment shown in Fig. 6, the apparatus includes a
first part 102 that is mounted in use on a mobile sink unit (or some other catering or washing appliance) and asecond part 104 that is designed to be mounted on a wall. - The
first part 102 includes a pair ofmale connectors 106 that are connected by means of flexible hoses (not shown) to the taps or faucets of the sink. Themale connectors 106 are mounted pointing upwards on afirst support plate 110 with their longitudinal axes substantially vertical. Thefirst support plate 110 is mounted on aframe 114, which includes twoslide rods 116 and astay bar 118, such that it can reciprocate vertically relative to the frame. Theframe 114 is attached to the rear of a standard sink unit, for example using bolts (not shown). - The
second part 104 includes a pair offemale connectors 120 that are connected by means of flexible hoses orrigid pipework 121 to hot and cold water supply ducts. Thefemale connectors 120 are mounted on asecond support plate 122 at the base of arigid metal sheet 124 that is designed to be mounted on a wall, for example withscrews 126. Thefemale connectors 120 are mounted substantially vertically with their open ends facing downwards. The male and female connectors 106,120 comprise standard self-sealing double shut off couplings. - At the upper end of the
metal sheet 124 there is provided anoperating handle 130 that is connected to ashaft 132 having a radially extendingcentral cam 134. Thecentral cam 134 is attached to theshaft 132 such that it extends backwards at an angle of approximately 180° from that of theoperating handle 130. Thecentral cam 134 is connected to avertical drive bar 140 by means of a pair ofhorizontal bars 142 that are located above and below theshaft 132. Thevertical drive bar 140 is connected to the metal sheet by means of abracket 143. - At the lower end of the
drive bar 140 there is provided adrive member 144 comprising another pair ofhorizontal bars 146 that extend forwards from thevertical drive bar 140. The free ends of thebars 146 are angled away from one another. Thedrive member 144 is arranged to engage thesupport plate 110 of saidfirst part 102 when themale connectors 106 are aligned with thefemale connectors 120. - When the
operating handle 130 is in the raised position, thedrive member 144 is positioned by thecam element 134, so that the gap between thehorizontal bars 146 is at the same height as thesupport plate 10. Thesupport plate 10 may thus be brought into engagement with thedrive member 144 by pushing the sink unit together with thefirst part 102 horizontally towards thesecond part 104. - Rotating the
handle 130 downwards through an angle of approximately 180° drives thesupport plate 110 upwards, thereby coupling the male and female connectors 106,120 to one another. Thehandle 130 may be latched by rotating it to an over-centre position, to prevent unintentional uncoupling of the male and female connectors 106,120. - When the
handle 130 is returned to the raised position, thesupport plate 110 is simultaneously driven downwards, disconnecting the male and female connectors 106,120 from one another. Once the connectors have been disconnected, thefirst part 102 and thesecond part 104 may be separated from one another simply by pulling the sink unit away from the wall. - The apparatus may optionally include a guide mechanism to assist with the correct alignment of the connectors as they are connected together. This guide mechanism may take the form of a pair of bevelled guide members (not shown) provided on either side of the wall-mounted
sheet 124, which engage the sides of theframe 114 and guide it into the correct position as the sink unit is pushed towards the wall.
