The The present invention relates to a hand shower, the Use adapted in domestic kitchens is, and in particular to such with a quick release coupling device for releasable Attaching the shower to a flexible water hose and with a housing with Water inlet and water outlet end, one mounted on the housing Valve for the selective passage of water and one on the water hose nozzle unit to be fastened, the solvable the housing to direct water from the hose into the housing. It allows the user to spray against facilities other shape, size and spray characteristics replace, without replacing the unit of the connection hose to have to.
hand showers are becoming increasingly popular for the domestic kitchenware for different Applications ranging from dishwashing until the brewing of vegetables pass. It will be for different Applications different nozzle sizes, shapes and spray patterns prefers. Although there are already various types of quick release coupling devices has been developed to make a quick and easy disassembly of a Spray nozzle to their To allow cleaning and replacement, but such constructions are often relatively complicated and therefore relatively expensive to manufacture and difficult to use and / or dependent from the use of special tools. Therefore have such facilities no widespread acceptance found.
In the US 2003/001028 A1 is z. B. a spray of the above described type, in which it for detaching the housing from the flexible water hose and for replacement by another shower body is necessary, the screw between the upper part and the lower part of the housing unscrew, at the same time sealed water channels through the housing parts to separate, one mounted in the first shower body and with the Water hose connected adapter to unlock the water hose from the first shower body pull it out, insert it into the second shower body, attach it to the adapter attach and then close both shower bodies again.
From the US 6,398,128 B1 are spray nozzles for fire-extinguishing installations having two parts which are interconnected by a Bayonetverbindung whose cooperating cams are arranged so that one of the two parts can be inserted axially into the other and then rotated. By the rotational movement, the cooperating cams engage like screw threads and pull the two parts axially against each other. The end position is secured by plastic ribs that releasably snap into pockets and increase the friction when turning the rotatable part towards loosening and separating. This is essentially a quick release connection of two rigid parts which are normally held stationary after assembly with respect to the water hose connected to them. The twisted connection can simply be released by turning it in the opposite direction. It is not a positive connection with stiff cams that lock the parts against relative movement.
It would be very desirable, in a hand shower a release mechanism to integrate, which has a simple structure, inexpensive to manufacture is, provides a secure connection with the water hose and one easy replacement of the shower body without replacing the unit of the water hose have to and without tools and complicated, multi-level work processes are necessary to get over one Variety of spray properties for different Applications to be able to. The present invention provides such a construction.
Briefly, the invention is characterized by a pair of wing portions projecting radially to opposite sides on the nozzle unit,
a pair of oppositely shaped seats in the housing for receiving the wing portions of the nozzle unit and for preventing rotational movement of the wing portions relative to the housing; spring members disposed in the housing for urging the wing portions into and against the seats;
a slot hole formed in the housing near the inlet end thereof for passing the nozzle unit having wing portions aligned with the passage opening disposed transversely of the seats so that by pushing the water hose with the nozzle unit attached thereto against the spring members into the housing, the wing portions of the seats are lifted and after subsequent rotation of the water hose with attached nozzle unit by about 90 degrees with respect to the housing for aligning the wing parts on the through hole of the hose and the nozzle unit are axially withdrawn from the housing and thereby the housing is removable from the hose ,
To re-attach the nozzle unit to the same or another shower body of different spray pattern or size gene, it is only necessary to align the protruding from the nozzle unit wing parts on the slot-through opening of the shower body, insert the nozzle unit into the housing so that the wing parts pass through the slot opening and reach behind the transverse wing seats, the flexible water hose and rotate the nozzle unit connected thereto 90 degrees with respect to the housing to align the wing portions with their respective seats, and then release the hose. The spring members urge the nozzle unit outwardly and the projecting wings attached thereto into and against their seats so that the hose and nozzle unit are connected to the shower body.

It will now be discussed in detail on the drawings. Thereafter, the hand shower according to the invention 10 a housing 12 , by means of a quick release coupling device 14 with a conventional flexible water hose 16 detachably connected, which is typically retractable installed next to a kitchen sink. The shower enclosure 12 has an upper housing part 12a with a down-reaching coat 18 who has an inner chamber 20 surrounds and with a lower housing part 12b is screwed. The upper housing part 12a also has an inner, down-reaching ring wall 22 at the top of the chamber 20 , The ring wall 22 extends around and delimits a second chamber 24 and forms at its lower end an inclined surface, which is a valve seat 26 represents.
A valve piston 28 is in the second chamber 24 mounted reciprocally displaceable and has at its upper end an operating knob 30 , while near its lower, in the flow direction front end an oblique annular surface 32 located to the valve seat 26 is adjusted. Sitting in an annular groove, an O-ring extends 34 around the slanted surface 32 to seal with the valve seat 26 to cooperate and one with 35 designated valve mechanism to form. A second O-ring 36 sits near the actuator button 30 on the valve piston 28 to with an annular inner wall 38 sealingly cooperate and permanently the leakage of water on the control knob 30 to prevent. To the valve 35 also includes a first coil spring 40 extending between a holding member 42 and one at the upstream end of the piston 28 below the valve seat 26 molded shoulder 44 extends and the piston to the in 1 closed position pre-loaded. The holding member 42 is in the lower end of the upper part of the case 12 defines and limits a central water passageway 43 and an annular circumferential groove 45 in the upper end surface, which is the lower end of the coil spring 40 absorbs and holds. An operating lever 46 for opening and closing the valve 35 is with its front end 48 at the top 12a of the housing 12 next to a front end cap 50 pivotally mounted, which with the water outlet end 52 of the housing 12 is screwed. Preferably, an aerator 54 at the outlet end inside the cap 50 appropriate. The shape of the pervator and the openings in the end face of the cap and the shape and size of the water outlet end determine the spray characteristics of the hand shower 10 ,
The lower part 12b of the shower enclosure 12 is with a plurality of axially extending circumferentially spaced ribs 56 - 60 provided on opposite sides of the inner wall. A pair of arched, horizontally arranged ribs 62 with a flat surface 62 ' are also formed on the inner housing wall and extend between the outer axial ribs 56 and 60 , The surfaces 62 ' are located below the upper ends of the ribs 56 and 60 and interact with them to form a pair of opposing seats 64 for radially projecting wing portions of a nozzle unit described below 66 to build. How out 7 and 10 Obviously, the ribs close 56 - 62 on the inner surface of the lower housing part 12b Peripheral areas of the interior of the lower part of the housing, so that they have a slot-through opening 68 limit, which is transverse with respect to the seats 64 the nozzle unit.
The flexible water hose 16 Plastic or rubber can with a conventional connector 70 be made of brass at its front end in the flow direction to be connected to a pressurized water supply can. Typically, the attachment of the hose is such that it is installed retractable adjacent a kitchen sink.
In the downstream end of the hose 16 is a nozzle unit 66 made of brass (see 2 ). As in 11 shown, belongs to the Dü seneinheit 66 an elongated nozzle 72 in the hose 16 protrudes and is fixed there, and a disc 74 with molded, opposite, projecting wing parts 76 , The disc 74 sits relatively free of play on the nozzle 72 but is rotatable about its central longitudinal axis. The upper end portion of the nozzle carries an O-ring in an annular groove 78 sealingly against the inner peripheral surface of a downwardly extending skirt portion 80 of the holding member 42 is present (see 5 ). The holding member 42 which is also the lower end of the coil spring 40 supports, as described above, additionally has an annular, recessed area 82 on its underside, which has an upper seat for a second coil spring 86 forms. The lower end of the spring 86 rests on a flat ring 88 off, the distance to the disc 74 above it around the nozzle 72 extends. A flat, annular support surface 90 is provided on the outer surface of the nozzle to the ring 88 support. If shell 12a and lower part 12b of the housing 12 screwed together, the coil spring 86 in a compressed state between the holding member 42 and the upper surface of the support ring 88 held, taking the ring against the nozzle 72 , the nozzle unit down (as shown 2 visible) and the wing parts 76 the disc 74 presses against their respective seats.
In use, water flows through the hose 16 and the nozzle 72 in the first chamber 20 in the shower enclosure 12 , When the operating lever 46 is depressed against the outer surface of the housing, it pivots about its front end 48 and press the operation button 30 down, the piston 28 inwards and the O-ring 34 from the valve seat 26 moved away. Then water flows under the line pressure in the two te chamber 24 around the piston 28 , further into a front chamber 25 and passes through the front end cap 50 from the hand shower, as indicated by arrows in 3 shown. As soon as the operating lever is released, the piston moves 28 by the force of the coil spring 40 back up, bring the O-ring 34 again in tight contact with the valve seat 26 and shuts off the water flow. To the pivot bearing on the housing part 12a for the operating lever 46 To obtain, is the upper housing part with a slot 92 provided for receiving a transversely extending, rounded, front end portion 94 of the operating lever 46 is designed so that after screwing the front end cap 50 on the front end of the upper housing part 12a the end cap 50 the slot 92 covers and holds the operating lever to the housing so that it can perform a pivoting movement to the depression of the piston 28 and thereby the opening and closing of the valve 35 to effect. It will be understood, however, that according to the invention, other constructions could be used to provide a valve mechanism for the showerhead 12 to realize and cause its opening and closing to selectively provide a liquid flow from the housing. In this position (see 2 ) pushes the coil spring 86 continuously against the ring 88 and push him against the nozzle 72 so that the wing parts 76 the nozzle unit 66 in and against their seats 64 are pressed and the nozzle unit is set in a waterproof arrangement in the housing. Because the disc 74 in the nozzle unit 66 with respect to the nozzle 72 is rotatable, the shower enclosure 12 with reference to the flexible hose 16 rotate during use without twisting or kinking the hose so as to facilitate the orientation of the hand shower in any desired direction.
To the shower enclosure 12 from the hose 16 this only needs to be pushed forward a short distance inwards with respect to the housing, whereby the wing parts 76 at the disc 74 from their respective seats 64 be lifted off (see 5 ), so that the hose and the disc can be rotated relative to the shower housing. By turning the hose 90 degrees, they will no longer pass through the seats 64 retained wing parts of the nozzle 72 rotatably mounted disc 74 also swung, the wing parts in alignment with the slot opening 68 be brought by the ribs 56 - 60 inside the lower housing part 12b of the showerhead are formed from. The hose and the nozzle unit can then easily through the opening 68 be pulled out of the showerhead to clean it and / or replaced by another housing with a different size or shape of the spray. After removal of the nozzle unit, the axially displaceable support ring 88 pressed against stops by the upper ends 56 ' and 60 ' the ribs 56 and 60 are formed, how out 4 seen. Other arrangements could be used to provide stops for the ring and seats for the wing parts in the lower part 12b of the shower enclosure 12 to obtain.
In order to mount the new shower enclosure, the above-described operation is simply reversed. The wing portions on the nozzle unit are aligned with the slot through hole in the lower part of the shower housing, and then the nozzle unit and the hose are pushed through and into the housing while the spring 86 is compressed. The tube is then rotated 90 degrees around the protruding wing parts 76 on the nozzle unit to their respective seats 64 align and then let go. The coil spring 86 then presses the nozzle unit down and pushes the wing parts in and against their seats, whereby the new shower enclosure is fixed to the hose.
It is a suitable decorative ring flange 96 provided, in addition to a removable outer bottom ring 98 around the lower end of the housing part 12b fits. The flange 96 has a downwardly extending tubular part 100 which is screwed to a conventional water pipe (not shown) and through which the flexible hose extends, so that it is a suitable receptacle for the shower enclosure 12 forms, see 2 ,
Thus, the present invention provides a very economical and easy-to-use, quick-release coupling device for exchanging handheld showerheads for similar showerheads with other spray jets in shape and size without having to replace the connection hose. The hand shower 10 is also very inexpensive to manufacture, since only a very small number of items is needed and these components, if desired, usually from cheap plastic and nylon materials are produced, although the nozzle unit and terminals are preferably made of brass. Incidentally, in the practice of the present invention, various changes and modifications can be made without departing from the scope. Insofar as these changes and modifications fall under the appended claims, they are considered to be part of the present invention.
