Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
257 words
Apparatus for detachably supporting friction-lining carrier members within a disc brake assembly, particularly for use in automotive vehicles, comprising: brake disc means secured for rotation with a vehicle wheel; brake caliper structure means secured to a part of a vehicle which is fixed relative to said brake disc means, said caliper structure means defining a recess extending laterally to both sides of said brake disc means, and including securing means; friction-lining carrier members having one surface thereof adapted for selectively detachable engagement of friction brake linings thereon, said friction-lining carrier members further including attachment means; mounting bracket means constructed in the form of a U-shaped pin adapted for simultaneous engagement with said securing means of said brake caliper structure means and said attachment means of said friction-lining carrier members, said securing means and said attachment means defining two sets of aligned apertures spaced apart in parallel relationship, the distance between said two sets of aligned apertures being substantially equal to the spacing between two free leg portions of said U-shaped mounting bracket means; and spring detent means attached to said brake caliper structure means and biased to engage with said mounting bracket means to retain same in engagement with said brake caliper structure means, said spring detent means including an undulated spring steel band adapted for flush mounting upon a surface of said brake caliper structure means, wherein said spring detent means further includes a depression positioned to engage with a cross member of said U-shaped mounting bracket member which connects said two free leg portions thereof.

Apparatus for detachably supporting friction-lining carrier members within a disc brake assembly, particularly for use in automotive vehicles, comprising: brake disc means secured for rotation with a vehicle wheel; brake caliper structure means secured to a part of a vehicle which is fixed relative to said brake disc means, said caliper structure means defining a recess extending laterally to both sides of said brake disc means, and including securing means; friction-lining carrier members having one surface thereof adapted for selectively detachable engagement of friction brake linings thereon, said friction-lining carrier members further including attachment means; mounting bracket means constructed in the form of a U-shaped pin adapted for simultaneous engagement with said securing means of said brake caliper structure means and said attachment means of said friction-lining carrier members, said securing means and said attachment means defining two sets of aligned apertures spaced apart in parallel relationship, the distance between said two sets of aligned apertures being substantially equal to the spacing between two free leg portions of said U-shaped mounting bracket means; and spring detent means attached to said brake caliper structure means and biased to engage with said mounting bracket means to retain same in engagement with said brake caliper structure means, said spring detent means including an undulated spring steel band adapted for flush mounting upon a surface of said brake caliper structure means, wherein said spring detent means further includes a depression positioned to engage with a cross member of said U-shaped mounting bracket member which connects said two free leg portions thereof.
Claim 3
Dependent Claim
57 words
Apparatus according to claim 1, wherein said spring detent member includes a mounting flange and said brake caliper structure means includes a mounting surface adapted for flush engagement with said flange of said spring detent means, said mounting surface lying within a plane which intersects a plane containing the axes of said two sets of aligned apertures.
Claim 4
Dependent Claim
50 words
Apparatus according to claim 2, wherein said spring detent means further includes a tongue portion which may be depressed, by external means, to overcome the normal bias of said spring detent means, thus permitting the removal of the leg portions of said U-shaped mounting bracket means from said aligned apertures.
Claim 5
Dependent Claim
65 words
Apparatus according to claim 3, wherein said brake caliper structure means includes a second recess, of relatively shallow dimension, in the region thereof adapted to receive said spring detent means, said second recess including lateral walls positioned so as to constrain said spring detent means from rotational displacement when said spring detent means is secured upon said mounting surface of said brake caliper structure means.
