[5 7 ABSTRACT A rod supported shower slide includes a sliding body having a bore at one side for engagement around a rod on which it is slidable and a bore at an opposite end which is provided for a shower-spray holding pin. A blind bore extends substantially perpendicular to the bore for the rod and in this bore is rotatably supported a pin which carries an eccentric having a curvature corresponding to the curvature of the rod upon which the device is engaged. The pin may be rotated to cause the eccentric to engage in holding engagement with the rod. The slide body has a form of approximately an isosceles trapezoid. The side faces on each side are planar and they taper conically toward each other from one side at the large diameter bore for receiving the rod to the other side to the small diameter bore for receiving the holding pin, and each side end is rounded.

9 Claims, 2 Drawing Figures Great Britain 248/221 PATENTEUJULZH \973 file, A ray/may Hi I ROD SUPPORTED SHOWER SLIDE WITH ECCENTRIC CLAMP BACKGROUND OF THE INVENTION 1. Field of the Invention I This invention relates in general to the construction of slide holders and in particular to a new and useful hand shower holder which is displaceably mounted on a rod member and which has a blind bore extending substantially perpendicular to the axis of the rod member which carries an eccentric for clamping the device at a position along the rod member.

2. Description of the Prior Art The present invention relates in particular to a device for displaceably holding a hand shower on a rod and which comprises a slide body which has a sleeve bore receiving the rod and a cross bore normal thereto which contains an eccentric clamp. The eccentric clamp serves to secure the hand shower holder on the vertically extending rod which may be fastened to a wall for example. The body also carries a holding pin at its opposite end which may be engaged with a hand shower. Hand shower holders are known including those which have clamping devices in the form of a pressure piece which is movable radially in relation to the rod and in which the pressure piece is pressed by means of a threaded part connected with a turning knob onto the surface of the rod when the holder is to be fixed in position. Usually due to the type of clamping device employed and the requirement that the sliding body should have a good sliding engagement on the rod so that it can be easily displaced, this requires a long sleeve bore for the slide and the known slide bodies aren't satisfactory in their design in several respects. The sliding bodies are made as a rule of a material such as solid brass, so that it is material to keep the body as small as possible both in respect to the cost and'in respect to the weight. It is also important that the body form not only appear attractive but that it exhibit a flat smooth and uninterrupted surface to the greatest possible extent so that there will be no dirty corners and the sliding body will be easy to clean.

SUMMARY OF THE INVENTION In accordance with the present invention there is provided a hand shower holder which comprises an improvement over the known shower holders inasmuch as it provides an attractively appearing body which is capable of easy sliding movement and which has an eccentric clamping device which has the advantage over the previously known devices in that it can be accommodated completely within the sliding body itself and it is capable of producing a more desirable clamping effect.

In accordance with the preferred form of the invention the sliding body is provided with opposite side faces of approximately isosceles trapezoid form and they extend into curved end portions at each end with one end being larger than the other in order to have a bore sufficient to accommodate the engagement rod so that the side faces extend substantially conically to each other and merge steadily from the widened end to the smaller end in which is located the pin for the shower holder.

The sliding body of the invention has many advantages over the prior forms of construction. it is very attractive and of very simple geometric form and it may be formed of a very small mass volume. It has practically only three external faces which are perfectly flat and smooth and exhibit no negative or positive discontinuities whatsoever, such as grooves, corners or pro- 5 jections. In addition, the sleeve bore, although it is limwhich provides a flat bottom face with a cylindrical pivot bearing. The pivot bearing provides a mounting for an eccentric contained in the blind bore and a handle is connected to the pin and projects from the side face of the body in a position in which it may be easily turned in order to tighten the eccentric against the rod member which is received in a bore which is in communication with a blind bore. The eccentric is formed of the curvature of the rod so that a line contact or even an area contact with the rod is effected rather than a point contact. This means that a much higher clamping force is attainable without danger of damage to the rod surface. The eccentric is advantageously made up of material such as plastic, or is coated with a plastic covering, so that there will be no damage to the rod during any clamping engagement thereof.

The eccentric comprises a cylindrical member with a surface formed in an axial direction corresponding to the curvature of the rod member which is accommodated in the rod receiving bore adjacent the blind bore. This insures that the eccentric will have a good frictional adhesion with the rod when it is clamped thereto, particularly when the eccentric is made of a plastic material or is coated with a plastic covering. A simple installation and reliable support for the eccentric shaft in an axial direction is obtained by an annular locking element which is seated in an annular groove of the cross bore so that it defines a surface at the end of the bore against which the eccentric may bear during its rotation. The eccentric shaft includes a projecting portion with a plurality of radial detent elements or projections which engage into the interior bore of a knob of plastic which is mounted thereover and secured by an axially extending screw.

Accordingly it is an object of the invention to provide an improved slide member which is engageable on a rod member for movement therealong and which is adapted to hold a shower and which is formed of a shape to provide a maximum slide area engagement with the rod member over which it is movable and is provided with an eccentric clamping element contained in a bore defined in the body which extends it in an angle to the axis of the rod member.

A further object of the invention is to provide a hand shower holder which includes a body made of generally isosceles trapezoidal configuration and which has a flat surface at each sidewhich extends substantially conically from a larger diameter bore portion, to accommodate a rod member on which the holder is slidable, to a smaller diameter bore portion for accommodating a shower pin holder, and having a body with smooth surfaces which are not subject to the accumulation of dirt and a shape providing a maximum of bearing surface area for sliding engagement with a minimum of mass volume.

A further object of the invention is to provide a shower holder which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference should be had to the accompanying drawing and descriptive matter in which there is illustrated a preferred embodiment of the invention.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. 1 is a side elevational view of a shower holder constructed in accordance with the invention;

FIG. 2 is a section taken along the lines 11-11 of FIG.

7 GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings in particular the invention embodied therein comprises a holder including a sliding body 1 which is engaged over a rod member 2 for vertical upward and downward movement therealong.

In accordance with the invention the slide body 1 includes a large diameter sleeve bore 3 for the reception of the guide rod 2 and the opposite end is provided with a small diameter bore for receiving a holding pin 6 on which a hand shower may be inserted. The body has the form of an isosceles trapezoid with the sleeve bore 3 being arranged along the base line 4 of the trapezoid. The outer part of the circumference has a thin wall 5 which forms a smooth curved transition between a first planar side wall 7 and a second planar side wall 8. The bore for the pin 6 and the sleeve bore 3 extend parallel to each other so that the holding pin 6 may be held at a fixed distance from the tubular support rod 2. The side faces of the side wall 7 and 8 are perfectly flat and extend conically to each other from the large diameter sleeve bore 3 to the small diameter bore for the pin 6 and they merge steadily into the rounded end wall 10 from the opposite rounded end wall 9.

In order to increase the sliding properties of the sleeve bore 3, the bore is lined with a plastic covering 11 which bears against the outer surface of the rod 2.

Extending perpendicular to the side face 8 there is arranged; a cylindrical cross bore or blind bore 12 which partly overlaps the sleeve bore 3. The blind bore 12 has a flat bottom or interior face 13 with a pivot bearing recess'l4 extending inwardly therefrom.

Clamping means in the form of an eccentric having a shaft 16 includes a concentrically arranged free end 15 which is rotatably supported in the pivot'bearing 14.

The shaft 16 carries an eccentric 17 which is affixed to the shaft 16 for rotation therewith. The eccentric 17 is in the form of a truncated cone with a concave generated side surface 18 adapted to the rounding of the rod 2. The eccentric 17 is made of a plastic material and it has a cylindrical guiding portion 19 which is guided during its rotation with the shaft 16 within the blind bore 12. The shaft 16 with the eccentric 17 is secured against axial displacement by an annular lock element 21 in the form of a washer which is mounted in an annular groove of the cross bore 12 adjacent the outer end thereof. The eccentric 17 or the shaft 16 is provided with a concentrically arranged cylindrical part which projects outwardly from the blind bore 12 and is provided with a plurality of radial detent elements or projections 22 which tightly engage within corresponding formations within a knob member 24. The knob member 24 is made of a plastic material and which is secured to the eccentric 17 and the shaft 16 by an axial screw 25.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
