Abstract
Abstract A brake mechanism for a roller blade having at least a pair of in-line wheels each suspended via an axle from a pair of frame members disposed on opposite sides of the wheels, comprised of two pair of disk shaped bearing surfaces, each pair fixed to opposite sides of a corresponding wheel coaxial with its axle, a pair of brake pad supports, each on an opposite side of the wheels, each having opposite end regions overlapping the bearing surfaces on both wheels, brake pads retained by the brake pad supports between the end regions of the brake pad supports and the bearing surfaces, apparatus for resiliently retaining the brake pad supports in positions with the brake pads spaced from the bearing surfaces, remote control apparatus for squeezing the brake pad supports together whereby the brake pads bear against the bearing surfaces, increasing friction therebetween and retarding rotation of the wheels.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
154 words
A brake mechanism for a roller blade having at least a pair of in-line wheels each suspended via an axle from a pair of frame members disposed on opposite sides of the wheels, comprising: (a) two pair of disk shaped bearing surfaces, each pair fixed to opposite sides of a corresponding wheel coaxial with its axle, (b) a pair of brake pad supports, each on an opposite side of the wheels, each having opposite end regions overlapping the bearing surfaces on both wheels, (c) brake pads retained by the brake pad supports between the end regions of the brake pad supports and the bearing surfaces, (d) means for resiliently retaining the brake pad supports in positions with the brake pads spaced from the bearing surfaces, (e) remote control means for squeezing the brake pad supports together whereby the brake pads bear against the bearing surfaces, increasing friction therebetween and retarding rotation of the wheels.
Claim 2
Dependent Claim
154 words
A brake mechanism for a roller blade having at least a pair of in-line wheels each suspended via an axle from a pair of frame members disposed on opposite sides of the wheels, comprising: (a) two pair of disk shaped bearing surfaces, each pair fixed to opposite sides of a corresponding wheel coaxial with its axle, (b) a pair of brake pad supports, each on an opposite side of the wheels, each having opposite end regions overlapping the bearing surfaces on both wheels, (c) brake pads retained by the brake pad supports between the end regions of the brake pad supports and the bearing surfaces, (d) means for resiliently retaining the brake pad supports in positions with the brake pads spaced from the bearing surfaces, (e) remote control means for squeezing the brake pad supports together whereby the brake pads bear against the bearing surfaces, increasing friction therebetween and retarding rotation of the wheels.
Claim 3
Dependent Claim
32 words
A brake mechanism as defined in claim 1, in which the frame members each contain a slot along the axis of the frame members, brake pad supports being contained within the slots.
Claim 4
Dependent Claim
23 words
A brake mechanism as defined in claim in which the bearing surfaces are comprised of disks fixed against each side of each wheel.
Claim 5
Dependent Claim
30 words
A brake mechanism as defined in claim 1, in which the brake pad supports are resiliently fastened to the frame members, the brake pads being located below the frame members.
Claim 6
Dependent Claim
124 words
A brake mechanism as defined in claim 1 in which the remote control means is a flexible control cable comprised of a flexible shaft surrounded by a sheath, the sheath comprising first bearing means for bearing against one of the brake pad supports, the shaft comprising second bearing means for pulling against the other of the brake pad supports in an opposite direction whereby the brake pad supports are drawn together, the other end of the sheath being connected to a handle, the flexible shaft being connected to a lever pivoted on the handle, whereby squeezing the lever toward the handle transfers tension and pressure to the brake pad supports, pulling them and the brake pad supports together against both sides of both wheels.
Claim 7
Dependent Claim
23 words
A brake mechanism as defined in claim 5, further including a brake locking mechanism for retaining relative positions of the cable and sheath.
Claim 8
Dependent Claim
68 words
A brake mechanism as defined in claim 6 in which the locking mechanism is comprised of a pin extending from either one of the handle or lever, and a hook rotatably pinned to the other of the handle and lever in a position such that when the handle and lever are squeezed together, the hook can be rotated over the pin and retain the handle and lever together.
Claim 9
Dependent Claim
34 words
A brake mechanism as defined in claim 2 in which the brake pad supports are retained on a guide bolt extending therebetween, and are separated by a compression spring retained around the guide bolt.
Claim 10
Dependent Claim
20 words
A brake mechanism as defined in claim 4 including resilient wedges disposed between the brake pad supports and the frame.
Claim 11
Dependent Claim
16 words
A brake mechanism as defined in claim 9 in which said wedges are comprised of rubber.
Claim 12
Dependent Claim
24 words
A brake mechanism as defined in claim 10 in which the bearing surfaces are comprised of disks fixed against each side of each wheel.
Claim 13
Dependent Claim
124 words
A brake mechanism as defined in claim 11 in which the remote control means is a flexible control cable comprised of a flexible shaft surrounded by a sheath, the sheath comprising first bearing means for bearing against one of the brake pad supports, the shaft comprising second bearing means for pulling against the other of the brake pad supports in an opposite direction whereby the brake pad supports are drawn together, the other end of the sheath being connected to a handle, the flexible shaft being connected to a lever pivoted on the handle, whereby squeezing the lever toward the handle transfers tension and pressure to the brake pad supports, pulling them and the brake pad supports together against both sides of both wheels.
Claim 14
Dependent Claim
23 words
A brake mechanism as defined in claim 12, further including a brake locking mechanism for retaining relative positions of the cable and sheath.
Claim 15
Dependent Claim
68 words
A brake mechanism as defined in claim 13 in which the locking mechanism is comprised of a pin extending from either one of the handle or lever, and a hook rotatably pinned to the other of the handle and lever in a position such that when the handle and lever are squeezed together, the hook can be rotated over the pin and retain the handle and lever together.
Claim 16
Dependent Claim
24 words
A brake mechanism as defined in claim 9 in which the bearing surfaces are comprised of disks fixed against each side of each wheel.
Claim 17
Dependent Claim
124 words
A brake mechanism as defined in claim 15 in which the remote control means is a flexible control cable comprised of a flexible shaft surrounded by a sheath, the sheath comprising first bearing means for bearing against one of the brake pad supports, the shaft comprising second bearing means for pulling against the other of the brake pad supports in an opposite direction whereby the brake pad supports are drawn together, the other end of the sheath being connected to a handle, the flexible shaft being connected to a lever pivoted on the handle, whereby squeezing the lever toward the handle transfers tension and pressure to the brake pad supports, pulling them and the brake pad supports together against both sides of both wheels.
Claim 18
Dependent Claim
23 words
A brake mechanism as defined in claim 16, further including a brake locking mechanism for retaining relative positions of the cable and sheath.
Claim 19
Dependent Claim
68 words
A brake mechanism as defined in claim 17 in which the locking mechanism is comprised of a pin extending from either one of the handle or lever, and a hook rotatably pinned to the other of the handle and lever in a position such that when the handle and lever are squeezed together, the hook can be rotated over the pin and retain the handle and lever together.
