INQINE SWIVEL HOLDER FOR SPRAY NOZZLESThis invention relates to an in-line swivel holder for spray nozzles.
Spray nozzles are widely used in the grocery trade to spray water onto fruit, vegetables, fish etc. in display cabinets to keep the produce in a fresh condition. It is necessary that these nozzles can be swivelled independently towards the front or rear of the cabinet to ensure appropriate cover, and that the nozzles can be independently shut-off when required.
Traditionally holders for nozzles are rigid and plumbed directly off from a permanent rigid water supply pipe with external shut-off devices which produces an overall bulky and untidy appearance for use in display cabinets on public view. This arrangement requires considerable time to install and replace individual components or to reposition holders when necessary.
According to the present invention there is provided an in-line nozzle holder which rotates on a central hub into which a rigid or flexible water supply pipe can be directly plumbed by means of 'quick release push-in pipe fittings' to provide an in-line assembly and allow the complete assembly to swivel on the supply pipe to direct the nozzle where desired.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which:Figure 1 shows the in-line swivel holder with a threaded connection to attach the nozzle and welded in type 'quick release push-in pipe fittings'.
Figure 2 illustrates an alternative screw in type 'quick release push-in pipe fitting'.
Figure 3 illustrates an alternative push on type 'quick release push-in pipe fitting'.
Figure 4 is a part view showing an alternative bayonet connection to attach nozzle.
Refering to the drawing the in-line swivel holder comprises an outer body 5 which rotates on a central hub 6. The central hub 6 has provision for welded in type 'quick release push-in pipe fittings' 7 at each end. Alternative hub ends are shown in Fig 2 for screw in type and in Fig 3 for push on type 'quick release push-in pipe fittings', and any combination of the three types of 'quick release push-in pipe fitting' can be provided in the central hub.
The outer body 5 includes a threaded connection to attach the nozzle andFig 4 shows an alternative bayonet connection to attach nozzle.
The outer body 5 and the central hub 6 when assembled become captive by means of an integral retaining device (not shown).
When installed in a water supply pipe 11, rotating the outer body 5 away from the SHUT position in the direction of arrow 10 allows the water to feed to the nozzle, and returning to the SHUT position closes the water supply by means of internal seals (not shown).
