3 Claims. c1. era-4s) The principal object of this invention is to provide an improved suction cup wall shower bracket which can be easily applied to a wall, has an increased and better distributed gripping effect,
' a will not loosen its hold under the twisting and 15 other more specific objects and advantages will be apparent to those skilled in the art upon a iull understanding of the construction of the im- Proved bracket.
A-preferred embodiment of the invention is so presented herein for the purpose of exempllflcation, but it will of course be appreciated that the invention is susceptible of incorporation in other structurally modified forms coming equally within the scope of the appended claims.
as In the accompanying drawing:
' Fig. l is a perspective view of theimp'roved suction cup wall shower bracket, showing the same-supporting a shower spray against a wall;
Fig. 2 isa side view of the bracket; so Fig. 3 is a plan view, with one of the suction cups shown in section; and
Fig. 4 is a front view. The novel shower spray support shown in the drawing includes a pair of horizontally spaced 3g rubber suction cups III which are arranged with their faces in the same vertical plane, and an outwardly projecting metal bracket Ii which is attached to the cups i0 and is provided with a downwardly inclined metal arm I! which termi- 40 nates below the cups in substantially the plane of the latter. The bracket ii is preferabLv made of round wire, in two horizontally spaced parallel side sections it, and the arm I! is also preferably made of round wire, in two horizontally spaced 4 parallel sidesections it.
The suction cups III are preferably provided with integrally formed button-like heads I! at the centers of the same, and the inner ends of the wire side sections it of the bracket ii are bent g0 outwardly away from each other and curved into eyes It which fit over the heads I! on the cups in tightly constricting engagement with the necks II of the heads. From the cups it the wire side sections II of the bracket ii extend horizontally u outward and are connected together at their outer ends by a U-shaped bend it, which bend is preferably formed at a slight upwardly tilted angle to the main part of the bracket. The upper ends of the wire side sections it of the arm ii are spread apart slightly and welded to the outer surfaces of I the wire side sections ll of the bracket Ii, and the lower ends of the sections it are connected together by a U -shaped bend il which bend is pref erably formed at a slight upwardly tilted angle to the main part of the arm.
In applying the bracket to a wall, the rims of the suction cups II are moistened-and pressed firmly against the wall to flatten out the cups and I evacuate the air from within the same. This will cause the cups to firmly grip the'wall, with the II lower end of the bracing arm I! in engagement with the wall beneath the cups on a vertical line which is equidistant from the centers of the latter.
The shower spraywhich ordinarily consistsof a spray head 20 and a length of rubber tubing 2 I-is assembled with the bracket from the bottom of-the latter. The spray head 2. is positioned in front of the upwardly tilted U-shaped bend it formed in the wire at the outer end' of the bracket, and the adjoining portion of the tubing is pushed up into the slot present between the wire side sections ll of the bracket, and is at the same time pushed back into the slot present between the wire side sections ll of the arm into the U- shaped bend ill at the backv of the bracket. a
The tubing will thereupon be snugly engaged by the bracket (1) at the U-shaped bend ll, (2) at the U-shaped bend i9, and (3) in the space present between the inner ends of the wire side portions it of the bracket, these three points of engagement being located at the corners of a right-angled triangle which is in the same vertical plane as the tubing when bent into the operative 'gooseneck formation shown.
The improved support is of extremely simple 0 yet sturdy construction, presents an attractive appearance, and is quite inexpensive to manufacture. It affords a much more satisfactoryv mounting for a shower spray than anything which has heretofore been devised for that puru pose. By using two suction cups instead'of the usual single cup, not only is a greater gripping power obtained, but t gripping power is distributed to better advantage. Because of the horizontally projecting arrangement of the so bracket with respect to the suction cups, and the addition of the bracing arm for the bracket beneath the cups on a vertical line equidistant from the latter, the cups are subjected to an indirect pull only, the bracket proper carrying g5 the weight of the shower spray and also taking up the sidcwise twisting movement of the tubing caused from the water pressure inside of the tubing. Any ordinary flexible shower spray can be put into or removed from the bracket'with the bracket in place on the wall and without any need for disassembling any of the parts oi! either the bracket or the spray. In assembling the shower spray with the bracket. the shower spray is inserted irom the bottom. As the water pressure within the tubing tends to push the same upwardly such water pressure will aid in keeping the spray parts in position and the latter will not slip out of place due to any increase in the flow of the water. The semiflexible character of the wire of which thebrackct is made makes it possible to bend the wire slightly so as to fit any popular size of tubing. By merely pulling or pushing the tubing immediately below the bracket the direction of discharge of the spray head can be adjusted. It can be placed so as to spray straight out or at any downwardly directed angle. The foot-like brace afforded at the bottom of the arm l2 against the wall acts as a fulcrum at that point and relieves the suction cups of the twisting and wrenching stresses to which the same are subjected in the ordinary types oi vacuum cup shower brackets. Furthermore, by using two vacuum cups instead of one, each cup acts as a fulcrum with respect to the other in absorbing sidewise stresses.
I claim: 1. A shower spray support for application to a wall, comprising a pair of horizontally spaced rubber suction cups arranged in the same vertical plane, and a narrow outwardlyprojecting bracket midway between the cups provided with laterally extending portions which are attached at their ends to the cups and provided beneath the outwardly projecting portion with a downwardly extending arm which terminates below the cups in substantially the plane of the latter, said bracket and arm both being of openwork construction with closely arranged horizontally spaced side portions between which the rubber tubing of the spray is frictionally held at a plurality of points in a vertical plane when bent into the form of a gooseneck.
2. A shower spray support for application to a wall for holding a length of rubber tubing equipped with a spray head in position to produce a shower, comprising a narrow outwardly projecting bracket provided with means for re ceiving and holding an upwardly bowed section of tubing in a vertical plane, said bracket being provided with a downwardly extending portion directly beneath the outwardly projecting portion thereof for engagement with the wall, and being provided at its sides with laterally extending portions, and a pair of horizontally spaced rubber suction cups secured at opposite sides of the bracket to the outer ends of said laterally extending' portion for engagement with the wall in laterally oflset relation to the bracket, each of said laterally offset cups providing a side fulcrum against the wall for the other cup to withstand lateral movement of the outer end of the interposed bracket under the wreathing action of the tubing caused by the pressure of the water passing through the tubing, and the downwardly extending portion of the bracket providing a bottom fulcrum against the wall for both of the cups to withstand downward movement of the outer end of the bracket.
3. A shower spray support for application to a wall for holding a length of rubber tubing equipped with a spray head in position to produce a shower, comprising an outwardly projecting bracket provided with means for receiving and holding an upwardly bowed section of tubing in a vertical plane, said bracket being provided with a bracing portion for engagement with the wall and being also provided with laterally extending portions, and a pair of horizontally spaced rubber suction cups secured at opposite sides 01 the bracket to the outer ends of said laterally extending portions for adhering engagement with the wall in laterally ofiset relation to the bracket, each of said laterally oflset cups providing a side fulcrum against the wall for the other cup to withstand sldewise movement of the outer end of the interposed bracket under the wreathing action of the tubing caused by the pressure 01' the water passing through the tubing, and the bracing portion of the bracket providing a bottom :fulcrum against the wall for both 01' the cups to withstand vertical movement of the outer end of the bracket.
