Abstract

A hand-held shower attachment (10) has a coaxially screwed-on handle (22) or a handle forming one piece with a hollow shaft (12) of the shower attachment (10) at the inlet end thereof.
The handle (22) consists of a tubular element (24) and of a handle sleeve (38). By axially displacing the handle sleeve a pair of coaxial blind holes (28, 30) of the tubular member are hydraulically connected to one another, whereby water is discharged from a sprinkler head (16). When the handle sleeve is in its opposite position the sprinkler head is locked against the pressure water supply. Thanks to large area end flanges (52, 54) of the handle sleeve (38), the latter can even be displaced by such disabled persons who are not able to control their finger movements.

Description

Handle on or for a hand-held shower attachment The invention concerns a handle on or for a hand-held shower attachment, exhibiting a hollow shaft which expands from an inlet end with a connection for a male thread coupler to an outlet end with a sprinkler head, in which handle is provided a shut-off valve.

Patent specification DE-A-3700927 reveals a hand-held shower attachment with a long handle, which ends in a sprinkler head, arranged at which is a rotary knob exhibiting two rotational positions, one of which enables the outlet sprinkler head to communicate with the hollow interior of the shaft and the other rotational position of which shuts off the outlet.

Patent specification EP-A-0656503 reveals a dishwashing sprinkler with a straight, cylindrical shaft, fixed to which is a coaxial sprinkler head with an interposed shut-off valve which may be opened by means of a pivot-mounted lever.

A hand-held shower attachment is revealed by patent specification EP-A-06S9490, exhibiting a handle with a sprinkler head, in which sprinkler head is arranged a control valve which can be operated by a finger button. The valve in this case does not shut off the water flow passage but rather enables selection between a central outlet and an outer ring of nozzles surrounding said central outlet.

For the physically disabled, who are frequently unable fully to control their body movements, operation of these known hand-held shower attachments is problematical. The physically disabled person must hold the handle of the shower attachment - 2 - 2i812~6 in one hand, and operate the actuation element of the shut-off valve of the hand-held shower attachment with the other hand, moving it in a specific direction.

The hand-held shower attachment according to EP-A-0656503 is particularly unsuitable for this purpose because the pivot-mounted lever constantly has to be held down with one hand against a spring load, while the sprinkler head itself is held at the handle with the other hand. The physically disabled person must, therefore, keep both hands on the shower attachment, a requirement which makes the handling of the shower attachment exceptionally impractical, irrespective of the fact that there is also a danger of injury because the fingers of the hand clasping the handle may become located under the pivot-mounted lever so that they may be caught when the pivot-mounted lever is pressed down. The state of the art according to DE-A-3700927 mentioned at the beginning requires of the physically disabled person that he or she holds the handle of the shower attachment with one hand and then, with the fingers of the other hand, grips the rotary knob at the end and turns it to the open position. These sequential, controlled movements are, however, often beyond the capabilities of the physically disabled.

The object of the invention is to provide a hand-held shower attachment or a handle for such a shower attachment so that the hand-held shower attachment can be operated with ease by disabled persons.

This problem is solved by the characteristic features of Claims 1 and 2.

According to Claim 1, the handle is a constituent component of the shaft of the hand-held shower attachment, and according to Claim 2, the handle is an accessory which can be screwed onto conventional hand-held shower attachments.

The axial shiftability of a control slider or spool in a cylindrical sleeve is known from patent specification EP-A-0607479. However, this constitutes a change-over valve for switching the pressure water supply between two actuators/consumers. The water connections are arranged at right angles to the axial direction of the control spool. The control spool is moved back and forth mechanically by a rocker arm. This change-over valve exhibits no axially displaceable handle sleeve and is therefore likewise not suitable for the creation of a handle for a hand-held shower attachment.

The essential advantage of the invention lies in the fact that the physically disabled person can hold the hand-held shower attachment at the handle sleeve and can activate the shower attachment by pushing it against the bath tub or his body without needing to use his other hand. This causes the handle sleeve to be moved relative to the shaft and the shut-off valve to be opened. The hand-held shower attachment according to the invention with its innovative handle thus facilitates one-handed operation.

According to a further development of the invention, the handle sleeve exhibits at both ends a large-area annular flange. The section of the handle sleeve between the flanges is provided with alternating annular ridges and annular valleys, so creating a surface with a longitudinally corrugated contour similar to that encountered in turned parts. The outside diameter of the annular flanges is substantially larger than that of the handle section located between them. These two annular flanges provide a positioning aid for the physically disabled person who may find it difficult to grip the handle of the hand-held shower attachment at the right position. The annular flanges also enable the handle sleeve to be shifted, for example, with the fist or the wrist if the physically disabled person is unable to move his fingers.

The invention is described in more detail on the basis of the drawing which represents an embodiment.

The single figure shows a cross-sectional view of a handle with shut-off valve, fixed to a hand-held shower attachment.

A hand-held shower attachment 10 consists of a hollow shaft 12 exhibiting at the inlet end a male threaded section 14, and at the outlet end a sprinkler head 16. Such a hand-held shower attachment 10 is widely available commercially and can be connected to a shower hose 18 by means of a threaded sleeve 20.

According to the invention, the hand-held shower attachment is connected to a handle 22 which features a tubular element 24 with a coupling sleeve 26, the latter exhibiting a female thread which fits the male thread of the sprinkler connection 14. The tubular element 24 features two coaxial blind holes 28, 30 which end at a transverse wall 32 and communicate at a point adjacent to this transverse wall with respective transverse holes 34, 36 which open at the outer surface of the tubular element 24.

The tubular element 24 has a circular cylindrical external surface on which a handle sleeve 38 is axially shiftable, of which the throughbore diameter corresponds to the outside diameter of the surface of the tubular element 24. Recessed into this throughbore are two annular grooves 40, 42. Three 0-rings 44, 46, 48 seal the two annular grooves 40, 42 against the tubular element 24. Annular groove 40 has a larger axial length than annular groove 42, and extends in the open position of the shut-off valve across both groups of transverse holes 34, 36. This open position is defined by the handle sleeve 38 being located at the rear radial surface of coupling sleeve 26. The figure shows the handle sleeve in its shut-off position, in which it is located against a threaded sleeve 50 which is screwed onto a threaded section at the inlet end of the tubular element 24. This threaded sleeve 50 - ~ 5 ~ 2181286 carries at its end an externally threaded section corresponding to that of the hand-held shower attachment 10.
This enables the connecting hose to be joined to the inlet end of the handle 22 by means of a screwed sleeve 20. Apart from the three 0-rings, the handle 22 thus consists of only three components, namely the tubular element 24, the handle sleeve 38 and the threaded sleeve 50.

The handle sleeve 38 has two large-area end flanges 52, 54 at its end faces, and an interposed handle section 56 with a corrugated contour. All the components of the handle 22, apart from the transverse holes 34, 36, are bodies generated by revolution.

The two 0-rings 44, 46 would suffice to perform the shut-off function of the shut-off valve. The third 0-ring 48 prevents pressure water from escaping between the handle sleeve 38 and the tubular element 24 when the handle sleeve 38 is axially shifted. A ventilation or drainage line can be connected to the second, narrower annular groove 42 in order to remove water from the hand-held shower attachment 10.

The handle 22 may, in an alternative embodiment, be formed integral with the hand-held shower attachment 10 as a single-piece construction, wherein the screwed connections 14 and 26 would be eliminated and the tubular element 24 would constitute a single-piece extension of the shaft 12.
