Abstract
Abstract A braking device for small recreational vehicles, such as roller skates or skateboards, having brake pads positioned in close proximity to the wheels of the recreational vehicle. The brake shoes are brought into operative contact with the wheels to effect braking under the action of a hand squeezable bulb. The braking assembly transmits the pressure created from squeezing a bulb through a conduit to a pressure activated member, such as an inflatable bladder, to displace the brake shoes to their braking position. Braking pressure may be maintained through the use of a valve. The braking conduit may be easily disengaged from the pressure activated member so that the recreational vehicle may alternatively be used in a conventional fashion having no braking capability.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
In combination, a brake assembly for an in-line roller skate comprising a boot and a frame having a plurality of wheels in tandem, said brake assembly comprising: a brake member disposed below said boot and carried by said frame, wherein said brake member is in close proximity to said wheels; a longitudinally extending pneumatic pressure-activated member interposed within said frame between said boot and said brake member; a conduit coupled on one end to said pneumatic pressure-activated member; a valve coupled to the other end of said conduit, said valve having an open and closed position for maintaining pressure in said pressure-activated member when set in said closed position; and a hand activated means coupled to said valve for applying a force through said valve, said conduit and said pneumatic pressure activated member to said brake member, for biasing said brake member into braking engagement with a plurality of said wheels.
Claim 2
Dependent Claim
151 words
In combination, a brake assembly for an in-line roller skate comprising a boot and a frame having a plurality of wheels in tandem, said brake assembly comprising: a brake member disposed below said boot and carried by said frame, wherein said brake member is in close proximity to said wheels; a longitudinally extending pneumatic pressure-activated member interposed within said frame between said boot and said brake member; a conduit coupled on one end to said pneumatic pressure-activated member; a valve coupled to the other end of said conduit, said valve having an open and closed position for maintaining pressure in said pressure-activated member when set in said closed position; and a hand activated means coupled to said valve for applying a force through said valve, said conduit and said pneumatic pressure activated member to said brake member, for biasing said brake member into braking engagement with a plurality of said wheels.
Claim 3
Dependent Claim
17 words
A braking assembly according to claim 1, wherein said pneumatic pressure activated member is an inflatable bladder.
Claim 4
Dependent Claim
17 words
A braking assembly according to claim 1, wherein said pneumatic pressure activated member is an air cylinder.
Claim 5
Dependent Claim
34 words
A braking assembly according to claim 1 wherein said conduit is attached to said pneumatic pressure-activated member by an interlocking coupling that allows the separation and reattachment of said conduit from said pressure-activated member.
Claim 6
Independent Claim
155 words
A method of braking the wheels of an in-line roller skate having a boot, a frame containing said wheels in tandem therein, and a brake assembly having in combination a longitudinally extending pressure activated pneumatic member disposed below said boot within said frame and in fluid communication with an operable hand grip means, wherein said hand grip means is coupled to a valve having an open and closed position for maintaining pressure in said pressure activated member when set in said closed position; and a frictional braking member positioned adjacent to said wheels between said pressure activated pneumatic member and said wheels, said method comprising the steps of: operating said hand grip means to transmit pressure to said pressure activated pneumatic member, thereby causing said pressure activated pneumatic member to expand and bias said braking member into frictional contact with a plurality of said wheels under the action of said expanding pressure activated pneumatic member.
Claim 7
Independent Claim
155 words
A method of braking the wheels of an in-line roller skate having a boot, a frame containing said wheels in tandem therein, and a brake assembly having in combination a longitudinally extending pressure activated pneumatic member disposed below said boot within said frame and in fluid communication with an operable hand grip means, wherein said hand grip means is coupled to a valve having an open and closed position for maintaining pressure in said pressure activated member when set in said closed position; and a frictional braking member positioned adjacent to said wheels between said pressure activated pneumatic member and said wheels, said method comprising the steps of: operating said hand grip means to transmit pressure to said pressure activated pneumatic member, thereby causing said pressure activated pneumatic member to expand and bias said braking member into frictional contact with a plurality of said wheels under the action of said expanding pressure activated pneumatic member.
Claim 8
Dependent Claim
48 words
A method of braking the wheels of an in-line roller skate according to claim 5 further comprising the step of setting said valve to said closed position for preventing said braking member from retracting from contact with said wheels after operation of said hand grip means is discontinued.
Claim 9
Dependent Claim
48 words
A method of braking the wheels of an in-line roller skate according to claim 5 wherein said conduit and said pressure activated pneumatic member are connected with an interlocking coupling that permits easy connection and disconnection of said conduit and said pressure activated pneumatic member from each other.
