Primary Examiner-Lawrence Charles Attorney, Agent, or Firm-Morris A. Case [57] ABSTRACT A two part resilient open cell foamed plastic is joined together. A strap is fastened between the two parts and extends outward in opposite directions from the joined parts. A pair of elastic straps are also joined between the plastic parts with both of these straps extending outward in the same direction which is at 90 from the first strap. The adjoining faces of the two plastic parts are joined part way around the periphery only, and are not joined on the side from which the elastic straps extend. One of the plastic parts has a series of outwardly extending holes into each of which a plurality of stiff fibers are embedded and extend outwardly from the foamed plastic.

BRIEF SUMMARY OF THE INVENTION This invention combines a brush, a flexible strap attached to the brush each end of which is grasped by a person to move the brush back and forth across the back in essentially a lateral motion. The vertical height of the brush is controlled by a pair of elastic straps; which are attached to the brush, and extend out from the brush at 90 from the first strap. The elastic straps are adjustably fastened together part way up the back then are separated with one strap passing over ones shoulder and fastens to one side of the first strap, and the other passes over the other shoulder and thence fastens to the opposite side of the first strap.

' The brush is made up of a pair of matching resilient open cell foamed plastic parts which are joined together. One of these parts have stiff filaments extending from the juncture between the two parts outward beyond the part to form bristles on the brush. The contacting faces of the two parts are bonded or joined by an adhesive that covers a strip part way around the periphery to leave the center area and the periphery along the side out of which the elastic straps extend unbonded to form a pocket between the two plastic parts. A pocket into which a bar of soap may be inserted.

DETAILED DESCRIPTION A back scrubber 10, has a brush 12, a flexible strap 14 and a pair of

elastic straps

16 and 18. The brush has a pair of

matching parts

20 and 22. These parts are both prepared from an elastomeric open cell foamed plastic such as flexible polyurethane, plasticized polyvinylchloride, and neoprene rubber. These foams will act in the same manner as a sponge, but will have much better strength and abrasion resistance. Part 20 has a series of essentially parallel holes 24, which extend through from the front to the fack face of the part. Each of these holes have a plurality of stiff filaments or fibers 26 of a material such as but not limited to nylon bonded together and to the inside of the hole at 28. The fibers extend out from the front face of the part an essentially uniform distance to form bristles for the brush. Alternatively the fibers may also have the inwardly extending ends embedded in a layer of adhesive 30 located along the inside face of part 20. The adhesive for bonding the fibers should have elastomeric properties. An adhesive such as natural or neoprene (polychloroprene) rubber, urethane or styrene-butadiene may be used. Strap 14 extends across the back face of part 20 and extends outwardly from the part in opposite directions as shown at 140 and 14b. The strap may be bonded at 32 as shown in FIGS. 4 and 5. This bond extends along the whole contact surface between the back surface of part 20 and the strap. The elastic straps l6 and 18 may be made up from a single strap which encircles strap 14 and then doubles back on itself; or it may be a pair of elastic straps that are fastened to strap 14 by sewwng or bonding. The elastic straps extend outward at an angle of about from strap 14, and are bonded at 32 to the back surface of part 20.

Parts

20 and 22 are bonded together along a straip 36 which extends inward from the periphery. This strip extends only part way around the periphery and does not cover near the edge adjacent the upwardly extending elastic straps. This gives a continuous unbonded area in the center and along the top edge of the two foamed parts to create a pocket 38 into which a bar of soap 40 may be introduced from the direction from which the elastic straps extend. The adhesive for all of the bonding should have elastomeric properties; so an adhesive ofa natural or neoprene rubber, urethane or a styrenebutadiene may be used. The bonding strip as best shown in FIG. 6, has a U-shape adhesive layer 36a on part 20, and a U-shape adhesive layer 36b on part 22 which when joined form a bond 36.

In an alternate embodiment the stiff filaments 26 are bonded together inside the holes 24, but are not em bedded in an adhesive layer along the back side of part 20, and the straps are joinedto

part

20 and 22 only along bonding strip 36. I

In use the straps may be as shown with the end 42 of elastic strap 16 fastened to strap extension 14b, and the end 44 of elastic strap 18 fastened to strap extension 14a or elastic straps l6 and 18 may be lengthened and one may grasp all four straps. When using the back scrubber as shown ones arms are placed between the straps with the brush against the back, an elastic strap over each shoulder and the ends 14a and 14b grasped and moved back and forth to move the brush across the back. The elastic straps have adjustable fastener 46 to assist in keeping the straps on the shoulders, and adjustable fasteners 48 and 50 to adjust the tension on the elastic straps. The back scrubber may be used as shown with the bristles against the back; or it may be turned around with the smooth surface on part 22 against the back. It may be used with a bar of soap inserted in the pocket to lather ones back or the bar may be removed and the brush used to remove the lather.
