Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
A washing device for a body comprising: a roller brush which includes two cylindrical brush elements mounted for rotation about a non-rotating brush axle, at least a portion of each element being of an elastic material; and at least one sensor non-rotatably mounted on said brush axle, said sensor positioned between said elements in a gap therebetween and spaced from the outer boundary surface thereof for producing a signal upon a predetermined type of contact with the body.
Claim 2
Dependent Claim
78 words
A washing device for a body comprising: a roller brush which includes two cylindrical brush elements mounted for rotation about a non-rotating brush axle, at least a portion of each element being of an elastic material; and at least one sensor non-rotatably mounted on said brush axle, said sensor positioned between said elements in a gap therebetween and spaced from the outer boundary surface thereof for producing a signal upon a predetermined type of contact with the body.
Claim 3
Dependent Claim
47 words
A washing device according to claim 1 wherein the sensor has a contact bar with a contact end directed toward the surface to be washed, said bar being deflected on contact with said body so that an electrical contact is established between a pair of electric terminals.
Claim 4
Dependent Claim
35 words
A washing device according to claim 2 wherein the end of the contact bar opposite said contact end is held in an elastic base (44, 46) in which the pair of electric terminals are located.
Claim 5
Dependent Claim
52 words
A washing device according to claim 1 wherein the sensor includes a contact element extending toward the surface to be washed, said element being located between two brush elements and being connected to the non-rotating brush axle at an elastic base on the axle in which base is arranged responsive contact means.
Claim 6
Dependent Claim
28 words
A washing device according to claim 1 wherein a motor for driving the brush is arranged in the gap between said two brush elements of the roller brush.
Claim 7
Dependent Claim
44 words
A washing device according to claim 1 wherein the brush elements are hollow cylinders mounted detachably on nave discs which discs are rotatably mounted on the non-rotating brush axle, a motor for driving the brush and the sensor being arranged between two nave discs.
Claim 8
Dependent Claim
101 words
A washing device for a body comprising: a roller brush which includes two cylindrical brush elements mounted for rotation about a non-rotating brush axle, wherein the brush elements are hollow cylinders detachably mounted on discs which are rotatably mounted on the non-rotating brush axle, at least a portion of each element being of an elastic material; at least one sensor positioned between two said discs in a gap between said brush elements and spaced from the outer boundary surface thereof for producing a signal upon a predetermined type of contact with the body; and a motor for driving the roller brush.
