MovABLE: SHOWER HEAD Filed Aug. 17. 1961 B ./55 :EIIEI- Z 56 :EIS- 1 '32 ATTORNEYS nite Stte This invention relates to a movable shower head which is adaptable for movement along horizontal tracks and relates specifically to a shower head of the type as shown in my copending United States patent application Serial No. 857,197, iled December 3, 1959 for Shower Head Adapter now Patent No. 3,005,995 granted Oct. 31, 1961.
Various devices have been constructed in the past for raising and lowering shower heads. One of the types of devices as shown in my copending patent application Serial No. 857,197 now Patent No. 3,005,995 employs a device Iwhich comprises a face plate formed with a vertical groove providing two horizontal rails on the side walls of the groove. A shower head connecting fitting is slidably mounted on the two tracks for vertical movement. The shower head is connected by a liexible hose to a source of water so that the shower head fitting can be raised or lowered on the tracks to appropriate levels for use.
Various fittings which have been used previously with this type of device have been proven to have certain difficulties such as being unadjustable in tension so that when the operator of the shower applies a heavy shower head the weight of the head might be too great and cause the fitting to fall to its bottom position. If the unadjustable tension is too strong it is too difficult for an operator to move the head from position to position. In addition many fittings suitable for this type of application have a tendency to nick or mar the face plate upon which the movable fitting is mounted. yOthers are bulky, cumbersome or involve a great number of parts.
It is a principal object of this invention to provide a simple fitting adapted to ride Within the two vertical tracks and which is readily mountable and demountable on the tracks. r[he novel tting also has the feature of means to obtain uniform adjustment of the pressure applied against the tracks so that the fitting can accom.- modate shower heads of varying weights with equal effectiveness.
Another object of this invention is to form the shower head tracks in a circular bead configuration and to form the head or fitting in two pieces which are spring urged together against a wide area of beaded tracks.
A feature and advantage of this invention is the provision of a guide extension on the fitting which prevents any metallic portion of the fitting from making contact with the face and thus prevents the fitting from marring or otherwise impairing the appearance of the face plate.
A further object of this invention is to provide a shower head fitting which is adaptable to ride between two vertical semi-circular vertical tracks in which the fitting has a front and rear face spring urged together between the two tracks. The side edges of the front and rear faces are complementary in configuration to the tracks so that they tightly nest against all walls of the semi-circular tracks and are formed of a plastic material which allows two pieces to ride smoothly in up and down reciprocal movement relative to the track.
Another feature and advantage of this invention is the provision of a plate which can be adj-usted relative to the back `piece of the yfitting in such a Way as to adjustably control the spring pressure urging the front and rear pieces of the fitting together.
Other objects of the present invention will become apparent upon reading the following specication and referring to the accompanying drawings in which similar fice characters of reference represent corresponding parts in each of the several views.
In the drawings:
FIG. 1 is a front view of the fitting of this invention showing the front plate fragmentarily upon which the fitting is mounted.
FIG. 2 is a rear view of the shower head fitting of this invention.
FlG. 3 is a side elevational view of FIG. 2 taken at line 3 3.
FIG. 4 is a cross-sectional view of the fitting taken at line 4 4.
FIG. 5 is another cross-sectional view taken at line 5 5.
Referring now to the drawings in the principal embodiment of this invention there is provided a face plate A being vertically apertured to provide two spaced apart parallel vertical tracks `15 on which the shower head fitting B is arranged to be vertically carried.
Each track is formed by curving the inner walls of the track inwardly in a semi-circular bead configuration as best seenin the cross-sectional views of FIGS. 4 and 5. It is desirable to have the outer face of the beads on a substantially uniform curvature.
Fitting B is formed by a front piece 20 and a rear piece 21 which are spring urged together by two spaced apart spring mechanisms 25. The side walls of the front and rear pieces when mounted together form concave side wall recesses generally indicated at Z6 which are complementary in configuration to the outer curvature of tracks 15. The spacing of the two side walls 26 are spaced a distance substantially equal to the spacing between the two tracks 15.
By this means the side walls of the front and rear pieces 20 and y21 form guides which ride in tightly nested contact with all faces of the circular tracks 15. By virtue of this tightly nested contact the fitting is restrained against forward, rearward and side to side motion and in addition provides a large bearing surface between the fitting and the tracks to allow the shower head to be raised and lowered in a smooth manner.
Front piece 20 is formed of metallic material on its out-er face and provides on its bottom portion a shower fitting nozzle 30 threaded at its end to receive a conventional shower head 31 and apertured through the threaded portion to a rearwardly extending pipe 32. The rearward extension 32 is of a diameter `sufficiently smaller than the spacing between the tracks 15 so that the rearward extension 32 can project rearwardly to the rear of plate A between Ithe tracks without making any contact with the track. The end of rearward extension 32 is threaded to receive a conventional fitting 35 by which a flexible hose 36 can be connected to the rearward extension.
The metallic face plate 38 of the front section of the fitting is provided with two internally threaded bosses 40.
A plastic liner 44 such as nylon or other similar material is mounted on the inside wall of metallic face plate 38. The liner forms the front sections side walls 26 and extends outwardly to a position closely adjacent the outer edge of the extremities by virtue of ia flange 48. Plastic liner `44 extends from the top of metallic face plate 38 to a position 'approximating the bottom of the rearward extension 32. Plastic liner 44 is apertured in conformity With bosses 40.
vFront piece 20 and rear piece 21 are urged together by spring mechanisms 25.
The Itwo spring mechanisms 25 each comprise a wide headed screw 50 threadably engaged With the threads of boss 40.
A cylindrical sleeve 51 is mounted on screw 50 and is tightly fitted against the end of the boss. The upper end of sleeve 51 is formed with a fiange 55. Springs 56 are biased against fiange 55 and urged against the rear wall of rear piece 21.
A plate member 58 is interposed between the two springs 56 and the back wall of rear piece 21. Plate 58 engages both of the spring '56 and is formed with an aperture between the two springs `at 60.
A screw 61 is mounted within yaperture 60 and engages the rear wall of rear piece 21. Screw 61 can therefore control Ithe position of displacement of plate 58 relative to the back wall of rear piece 21. This accomplishes 4the greater tension of the springs 56 which creates .a tighter biasing of the front and rear pieces together. -Loosening of screw 61 creates the reverse effect.
Tracks are of a radius in retalion lto the concave recesses formed by the front and lrear pieces so that the front and rear pieces will be spaced apart. Thus the tension effected by spring mechanisms will effectively change the biasing force of the front and rear pieces against tracks 15.
It can readily be seen .that the device can be disassembled by unscrewing the two screws 50 wherein the front and rear pieces .are readily removable. Assembly i-s eected by revers-ing the process.
Adjustment of tension is then effected by screwing screws 61 to a proper placement so that the head fitting will have the requisite amount of frictional impedance against the tracks to prevent it from falling inadvertently.
The Itensioning should be such that it would not unnecessarily restrict the smooth sliding action of the fitting when it is desired to change its elevation or position on the track.
Liners 44 and rear pieces 21 are formed of plastic material so that they can engage the tracks without endangering scratching of the tracks. It can thus be seen that `the device can easily slide from its uppermost to its lowermost position within the track.
In operation hose 36 would be flexible so that the water communication can be had through shower head 31 regard-less of the position of the fitting relative to the track.
The extension of plastic liner 44 with its flange 48 provides means for preventing the metallic frontal portion of the fitting from making contact with face plate A.
