Abstract
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.

A device for rubbing a persons back comprising: a. a joined two part flexible open cell foamed plastic, b. means extending from the foamed plastic for scratching, c. means extending from the foamed plastic for grasping by a person to allow oNe to move the foamed plastic with scratching means back and forth across the back, and d. elastic means extending upwardly from the foamed plastic for controlling the vertical position of the device.
Claim 2
Independent Claim
74 words
A device for rubbing a persons back comprising: a. a joined two part flexible open cell foamed plastic, b. means extending from the foamed plastic for scratching, c. means extending from the foamed plastic for grasping by a person to allow oNe to move the foamed plastic with scratching means back and forth across the back, and d. elastic means extending upwardly from the foamed plastic for controlling the vertical position of the device.
Claim 3
Dependent Claim
24 words
A device as in claim 1 further comprising a pocket between the two parts of the foamed plastic for accepting a bar of soap.
Claim 4
Dependent Claim
104 words
A back scrubber comprising: a. a joined two part elastomeric open cell foamed plastic material with one of the two parts having a series of holes extending from the juncture between the two parts outwardly, b. a plurality of stiff filaments located in and extending outwardly beyond each of the holes in the foamed material, c. a first strap attached to and extending outwardly in opposite directions from between the two parts of foamed material, and d. a pair of elastic straps attached to and extending outwardly from between the two part foamed material at about 90* from the direction of the first strap.
Claim 5
Dependent Claim
104 words
A back scrubber comprising: a. a joined two part elastomeric open cell foamed plastic material with one of the two parts having a series of holes extending from the juncture between the two parts outwardly, b. a plurality of stiff filaments located in and extending outwardly beyond each of the holes in the foamed material, c. a first strap attached to and extending outwardly in opposite directions from between the two parts of foamed material, and d. a pair of elastic straps attached to and extending outwardly from between the two part foamed material at about 90* from the direction of the first strap.
Claim 6
Dependent Claim
26 words
A back scrubber as in claim 3 further comprising: a fastener holding the elastic strap together at a point part way out from the foamed material.
Claim 7
Dependent Claim
30 words
A back scrubber as in claim 4 wherein the fastener holding the elastic straps together is adjustable to allow fastening the straps together at varying distances from the foamed material.
Claim 8
Dependent Claim
65 words
A back scrubber as in claim 4 wherein the end of one of the pair of elastic straps adjustably fastens to the first strap at a point out from one side of the joined open cell plastic material, and the end of the other elastic strap adjustably fastens to the first strap at a point out from the opposite side of the joined plastic material.
Claim 9
Dependent Claim
37 words
A back scrubber as in claim 3, further comprising a pocket between the two parts of the foamed material for accepting a bar of soap inserted from the direction from which the pair of elastic straps extend.
Claim 10
Dependent Claim
162 words
A bath brush for scrubbing ones back comprising: a. a first strap, b. a second and elastic strap comprising a pair of straps fastened to the first strap with each in the pair of elastic straps extending in the same direction at about 90* from the first strap, c. an elastomeric open cell foamed plastic part having a plurality of essentially parallel holes extending therethrough, d. a plurality of stiff filaments bonded into each of the holes and extending beyond the foamed plastic on one side, and having the straps bonded to the opposite side, and e. a second elastomeric open cell foamed plastic part joined on the strap side to the first foamed plastic part with a bond between the adjoining surfaces on a strip extending part way around the periphery to leave unbonded the center area and that part of the periphery adjacent the elastic strap to form a pocket between the two parts for accepting a bar of soap.
Claim 11
Dependent Claim

Claim 13
Dependent Claim
56 words
A bath brush as in claim 9, further comprising: a. an adjustable fastener between the end of one of the pair of elastic straps and one side of the first strap, and b. an adjustable fastener between the end of the second of the pair of elastic straps and the opposite side of the first strap.
Claim 14
Independent Claim
159 words
A method of preparing a bath brush for the back comprising: a. selecting a pair of matching resilient open cell plastic sponges, b. introducing a plurality of essentially parallel holes through one of the sponges, c. inserting a plurality of stiff filaments into each of the holes with the filaments extending outward at the face side of the plastic sponge and adhering to the sponge inside the holes at the back side of the sponge, d. looping an elastic strap over a flexible strap and bonding the straps to the back of the sponge, having the holes with filaments with the elastic strap at 90* from the flexible strap, and e. bonding the secOnd in the pair of resilient open cell plastic sponges to the back side of the first sponge with the bond along a strip adjacent to and extending part way around the periphery, having the bond discontinuous on the side toward which the elastic strap extends.
