Roller skate assembly with braking device

Abstract

The skate assembly includes a bogie frame including a brake pad, a pad support and a wear compensation system. Such a system includes an articulation, enabling the pad support to be lifted relative to the rest of the frame, and a movable locking lever. During braking, the lever is fastened into the slots provided for fastening the lever. When the pad has worn out, the user can unlock the lever and rotate the support so as to bring again the pad close to the ground. In this way, notwithstanding the wear of the pad, the need for excessively tilting the skate for braking is avoided. The adjustment system is very simple from the manufacturing standpoint, and is easy and quick to lock.

1 . A roller skate assembly with a braking device, the assembly including a bogie frame, arranged to receive and secure a shoe in its top portion and a plurality of wheels in its bottom portion, which wheels enable the roller skate assembly to rest and roll upon a rolling surface, wherein the bogie frame further includes: 
 a brake pad, arranged to brake the roller skate by interacting with the rolling surface;    a pad support, secured to the rest of the bogie frame and having the brake pad secured thereto;    a wear compensation system, arranged to enable adjusting the position of the brake pad relative to the rest of the bogie frame so as to compensate the wear of the brake pad, wherein the wear compensation system includes: 
 an articulation, arranged to enable the pad support to be displaced relative to the rest of the bogie frame;  
 a movable fastening member arranged to reversibly move from a locked condition, in which the pad support substantially cannot be displaced relative to the rest of bogie frame, to an unlocked condition, in which the pad support substantially can be displaced relative to the rest of bogie frame.  
   
   
   
       2 . The assembly as claimed in  claim 1 , wherein the wear compensation system further includes a fastening part, wherein the movable fastening member can move to the locked condition through a displacement in a locking direction, and can move to the unlocked condition through a displacement in an unlocking direction, and wherein the movable fastening member and the fastening part are arranged to mutually engage so as to prevent displacement of the pad support caused by the push of the brake pad during braking, and are further arranged so that, when they are mutually engaged, the movable fastening member is pushed further towards or is maintained in the locked condition due to the push of the brake pad during braking.  
   
   
       3 . The assembly as claimed in  claim 2 , wherein the movable fastening member and the fastening part are arranged so that, when they are mutually engaged, the movable fastening member is pushed further against the fastening part in the locking direction due to the push of the brake pad during braking.  
   
   
       4 . The assembly as claimed in  claim 2 , wherein the movable fastening member and the fastening part are arranged so that, when they are mutually engaged, the movable fastening member rests against the fastening part in the locking direction due to the push of the brake pad during braking, so that said member cannot be substantially displaced further in the locking direction.  
   
   
       5 . The assembly as claimed in  claim 1 , wherein at least one out of the movable fastening member and the pad support is arranged to move from the locked condition the unlocked condition and/or vice versa by a rotation and/or a translation relative to the rest of the bogie frame.  
   
   
       6 . The assembly as claimed in  claim 1 , wherein the pad support and the movable fastening member are so arranged that the forces applied by the pad support to the movable fastening member when the brake pad is being operated produce a resultant moment tending to keep or to push the movable fastening member in or to the locked condition.  
   
   
       7 . The assembly as claimed in  claim 1 , wherein the pad support and the movable fastening member are so arranged that the forces applied by the pad support to the movable fastening member when the brake pad is being operated produce a resultant force tending to keep or to bring the movable fastening member in or to the locked condition.  
   
   
       8 . The assembly as claimed in  claim 2 , wherein the fastening part is located on either of the following parts: the pad support; a portion of the bogie frame other than the pad support.  
   
   
       9 . The assembly as claimed in  claim 1 , wherein the movable fastening member includes one or more of the following members: a pivoting lever, a rotating cam, a rotating balance, a fastening tooth, a translating lever or pin or cam.  
   
   
       10 . The assembly as claimed in  claim 1 , wherein the movable fastening member includes a first projection or recess, arranged to engage a recess or projection, respectively, in the pad support, so as to prevent the latter from being lifted or lowered relative to the rest of the bogie frame.  
   
   
       11 . The assembly as claimed in  claim 2 , wherein the movable fastening member includes a first projection or recess arranged to engage a recess or projection, respectively, in the pad support, as well as a second projection or recess, the second projection or recess being arranged to rest against the fastening part in the locking direction due to the push of the brake pad during braking, so as to make the first projection or recess substantially prevent the pad support from being lifted or lowered relative to the rest of the bogie frame.  
   
   
       12 . The assembly as claimed in  claim 1 , wherein the movable fastening member includes a fastening tooth and/or a first fastening projection arranged to cooperate with the pad support so as to prevent the latter from being lifted or lowered relative to the rest of the bogie frame, and wherein said tooth and/or projection has a height substantially not lower than about 2 mm, and preferably substantially not lower than about 3 mm.  
   
   
       13 . The assembly as claimed in  claim 1 , wherein the movable fastening member has from one to four fastening teeth and/or first fastening projections arranged to cooperate with the pad support so as to prevent the latter from being lifted or lowered relative to the rest of the bogie frame.  
   
   
       14 . The assembly as claimed in  claim 1 , wherein the wear compensation system includes a resilient return member arranged to push the movable fastening member in the locking direction.  
   
   
       15 . The assembly as claimed in  claim 1 , wherein the assembly defines a heel region in correspondence of the heel region of the shoe, and the movable fastening member is arranged to pivot about a rotation axis passing close and/or below the heel region or the roller skate assembly.
