Back cleanser and balm applicator
BACKGROUND OF THE INVENTION 
     This invention involves a device and method of cleansing a person&#39;s back as well as application of a balm to the person&#39;s back. 
     Without a second person or some type of device, it is essentially impossible for a person to scratch his or her own back, scrub all of his or her own back in the shower or bath, or apply a balm to the small of his or her own back. Throughout this Specification and Claims, the term &#34;balm&#34; is intended to include any liquid that soothes, heals, or medicares a skin condition. The balm includes lotions, which are typically liquid aqueous suspensions or emulsions for skin conditions, as well as ointments and palliatives for soothing or treatment of dryness, itching, infection, pain, or the like. 
     A number of devices directed to washing the back include U.S. Pat. No. 4,020,519 to Robison which describes a stationary back scrubber with a resilient backing adhesively adhered to the wall above a bathtub on which a rubber sponge or polyurethane sponge is attached in segments on the front face. A liquid detergent reservoir is cut into the top of the resilient backing opening to the sponge panels on the front. A repositionable T-shaped back cleaning device covered in cloth is described in U.S. Pat. No. 3,750,226 to Morgan. The lotion is released into a sponge applicator on the end of the device by a valve mechanism. The summary of German Patent No. 2426432 describes a shower fitting for back massage and washing which includes a massage plate with full padding and a textile covering. The plate may be connected at the back to a water pipe as it is equipped with water jets or nozzles. A back device is described in U.S. Pat. No. 1,358,733 to Heine which includes a sponge attached to a tube feeding liquid from a reservoir to the sponge which may be applied to those portions of the body that may be reached. A back washing apparatus is described in U.S. Pat. No. 3,478,369 to Ensley with a foam covered horizontally disposed corrugated surface. A back scrubber is described in U.S. Pat. No. 4,040,132 to Braun with horizontally positioned cylindrical scrubbers. A wall-mounted back brush, described in U.S. Pat. No. 4,943,018 to Glaser, et al, is held in a vertical position on the wall with suction cups. A massaging and washing device is described in U.S. Pat. No. 3,577,985 to Guffin using horizontally disposed rollers. A concave back cleaning device utilizing a cloth covered panel is described in U.S. Pat. No. 3,289,215 to Kennedy. A foot washing device is described in U.S. Pat. No. 4,003,372 to Willoby utilizing a pliable corrugated panel. A suntan applicator is described in U.S. Pat. No. 5,087,138 to Terbrusch, et al with a hollow handle into which suntan lotion is poured. Hand held soap holders and scrubbers are described in U.S. Pat. Nos. 2,900,757, 5,011,316, and 5,070,552. A wall mounted bathroom fixture including brushes and sponges for washing a person&#39;s back is described in U.S. Pat. No. 4,417,362 to Walker. In U.S. Pat. No. 3,631,560 to Atkins a brush mounted with suction cups on a bathtub sidewall is described. 
     None of these devices provide as effective accessing of the recesses of a person&#39;s back nor provide as effective application of the balm as the invention described herein below.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Device 20 as illustrated in FIGS. 1, 2, and 3 is a base unit of the invention including base panel board 22 which is rigid, constructed of wood, impregnated or coated with waterproof coating or of rigid plastic. Suction cups 24 located on rear face 34 of base panel 22 securely, but temporarily, attach device 20 to a wall such as a shower stall wall or a ceramic or plastic wall over a bathtub. The device may be easily removed and attached to a wall away from a drain for use when dry or for application of various balms from applicators on the device described herein below. Device 20 is further constructed of flexible closed cell urethane foam pad 26 which is encased and covered with plasticized polyvinyl chloride film 28 which is further covered with nylon plastic netting 30. The edges of film 28 and netting 30 are attached with adhesive or mechanical fasteners to the edge of base board 20. Suction cup attachments 24 are attached with bolt 27 extending through a hole in board 22 threaded on nut 25 which is tightened to secure suction cup 24 to the rear of device 20. In FIGS. 4 and 5, base unit 20 has been prepared for use by adding terry cloth cover 38 which is held in place by elasticized border 42. Cover 38 holds and covers spinal bar unit 40 which is shown in FIGS. 6 and 7. Unit 40 is attached to an inner surface of cover 38. Spinal bar 40 includes upper section 44 and lower section 46. Upper strap 48 and lower strap 50 extend over sections 44 and 46, respectively. Straps 50 and 52 are each stichably attached at their respective ends to cover 38 leaving a center section free extending horizontally across central section 32 of unit 20. Straps 48 and 50 are respectively positioned at upper and lower positions on section 32 so that base panel 52 of unit 40 may be slipped in and out of the attachment mechanism. Base panel 52 is constructed of a rigid or semi-rigid thermal plastic polymer or a rigid or semi-rigid high density closed cell foam to allow it to engage and disengage from straps 50 and 52. Unit 40 also includes block members 54 which are spaced apart in a vertical alignment with an arcuate shape curved horizontally. It is preferred to have at least four lock members constructed of a semi-rigid plastic or rubber or high density close cell foam adhesively attached to base panel 52. Foam interlayer 55 is cut to the same shape as base panel 52 and is preferably a soft flexible polyurethane closed cell foam. The entire unit 40 is covered and heat sealed with flexible film 56 which may be plasticized polyvinyl chloride or a polyolfin. In a second embodiment cover 56 is attached through drawstring 60 to device 20 as shown in FIGS. 8 and 9. Cover 58 is constructed of a waterproof plastic coated paper that may be disposed after use. Inside surface 62 has a relatively high coefficient of friction against netting 30 reducing the tendency for cover 58 to slide. Drawstring 60 is trained through hemmed edge 64. On the front of cover 58 are ten individual applicators 66 which may be permanently attached to cover 58 with contact adhesive or temporarily attached through VELCRO® fabric attachments. Each applicator 66, as shown in FIG. 11, includes flexible closed cell foam disk 70 backed with plastic sheet 68 which is in turn attached to cover 58. Slit 72 is cut a medial distance into the front face of foam disk 70 to receive folded waterproof paper sheet 74 with cotton ball 76 adhesively attached into the V-shaped paper shape. Supplies of a combination of cotton ball 76 on paper 74 may be used and thrown away after application of a balm. A balm may be applied directly to cotton ball 76 after it is in place on foam disk 70 or may be first applied to the ball and the ball then inserted into slot 72. Applicators 70 may be strategically placed to reach the inaccessible areas of a person&#39;s back or the particular areas that need treatment. In FIG. 10, cover 78 is constructed of a netting is attached on base unit 20. Although the main body of cover 78 is shown as a netting, it may just as easily be an impervious sheet such as coated paper or a plastic film. If the main body of cover 78 is an impervious film, impervious sheet 80 will not be necessary. In this embodiment impervious sheet 80 extends over the front face of cover 78 and under left side pockets 82, right side pockets 84, and center pockets 86. These pockets are constructed of porous nylon netting which allows any fluids to easily seep through and be applied to a person&#39;s back. Side foam applicators 88 and center foam applicators 90 are opened cell flexible plastic foam blocks. As shown in FIG. 13, center foam applicator 90 includes a plasticized PVC backing sheet 92 formed in cup-shape 92 at the bottom encasing foam 96. With appropriate impervious covering of the device vinyl backing 92 is not necessary. 
     While this invention has been described with reference to specific embodiments disclosed herein, it is not confined to the details set forth and the patent is intended to include modifications and changes which may come within and extend from the following claims.
