Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 97 words
An audible alarm sounding pad clip device for disc brakes consisting of a side portion comprising an elongated U-shaped resilient member is adapted to be attached to the backing metal plate of a friction pad and includes a loop formed in the base portion of said resilient member and another side portion of the U-shaped member arranged to be resiliently in contact with the friction pad guiding face of a support with the end of the same side portion extending to a point coinciding with an allowable limit of wear of the lining of said friction pad.
Claim 2
Dependent Claim 97 words
An audible alarm sounding pad clip device for disc brakes consisting of a side portion comprising an elongated U-shaped resilient member is adapted to be attached to the backing metal plate of a friction pad and includes a loop formed in the base portion of said resilient member and another side portion of the U-shaped member arranged to be resiliently in contact with the friction pad guiding face of a support with the end of the same side portion extending to a point coinciding with an allowable limit of wear of the lining of said friction pad.
Claim 3
Dependent Claim 23 words
A device as defined in claim 1 wherein said base portion of the long U-shaped resilient member is bent sideways toward said support.
Claim 4
Dependent Claim 58 words
A device as defined in claim 1 wherein said other side portion which is resiliently in contact with said support extends in a long straight form from the backing metal plate of the friction pad on the side opposite to the lining of the friction pad and continues on the loop shaped base portion of said resilient member.
Claim 5
Dependent Claim 63 words
A device as defined in claim 1, wherein a hole is provided in the end of said one side portion of the long U-shaped resilient member to form a hook portion there; while a protrusion which is arranged to stick out from the backing metal plate is disposed through said hole; and the protrusion is calked into a shape of a rivet head.
Claim 6
Dependent Claim 92 words
An audible alarm sounding pad clip which is composed of a long U-shaped resilient material comprising one side portion 6b to be attached to the backing metal plate 4 of the friction pad; another long-legged side portion 6c which is resiliently in contact with said guiding face of the support with the end of the side portion 6c extending to a point coinciding with an allowable limit of wear of the lining of said friction pad; and a base portion 6a which is bent sideways in the outer direction toward the support.
Claim 7
Dependent Claim 92 words
An audible alarm sounding pad clip which is composed of a long U-shaped resilient material comprising one side portion 6b to be attached to the backing metal plate 4 of the friction pad; another long-legged side portion 6c which is resiliently in contact with said guiding face of the support with the end of the side portion 6c extending to a point coinciding with an allowable limit of wear of the lining of said friction pad; and a base portion 6a which is bent sideways in the outer direction toward the support.
