Abstract
Abstract An adjustment device for a roller skate including a support for an item of footwear and at least two aligned wheels. The device has the peculiarity of having, between the at least two aligned wheels, a screw for adjusting the interspace therebetween, as well as kinematic systems for interconnection with the support. The device allows to vary the distance between the support for the item of footwear and the axle of one or more of the aligned wheels of the skate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
196 words
Adjustment device for a skate comprising a support for an item of footwear and at least two aligned wheels each having a shaft, wherein adjustment means are provided between said at least two aligned wheels and are suitable for varying the distance between said support and the shaft of said at least two aligned wheels, the adjustment device comprising a carriage, between which at least one of said at least two aligned wheels can be arranged, and a frame, within which said carriage is slidingly associated and with which said item of footwear is externally coupled, at least one resilient member being provided between said carriage and said frame, the adjustment device further comprising a carriage which has a substantially C-shaped configuration and having first wings, said carriage being slidingly associated inside said frame which is C-shaped, said item of footwear being rigidly associated on said frame, said frame having second wings which are arranged parallel to said first wings and are slightly longer than said first wings, first slots being defined longitudinally on said second wings, pivot means for fastening said wheels at said carriage wings being able to slide freely at said first slots.
Claim 2
Dependent Claim
196 words
Adjustment device for a skate comprising a support for an item of footwear and at least two aligned wheels each having a shaft, wherein adjustment means are provided between said at least two aligned wheels and are suitable for varying the distance between said support and the shaft of said at least two aligned wheels, the adjustment device comprising a carriage, between which at least one of said at least two aligned wheels can be arranged, and a frame, within which said carriage is slidingly associated and with which said item of footwear is externally coupled, at least one resilient member being provided between said carriage and said frame, the adjustment device further comprising a carriage which has a substantially C-shaped configuration and having first wings, said carriage being slidingly associated inside said frame which is C-shaped, said item of footwear being rigidly associated on said frame, said frame having second wings which are arranged parallel to said first wings and are slightly longer than said first wings, first slots being defined longitudinally on said second wings, pivot means for fastening said wheels at said carriage wings being able to slide freely at said first slots.
Claim 3
Dependent Claim
71 words
Device according to claim 1, wherein means for guiding the mutual position of said carriage and of said frame are arranged at said second wings of said frame, said means being constituted by a pair of pivots which protrude laterally outside said first wings of said carriage, said pivots sliding within adapted second slots defined longitudinally to said second wings, resilient pads being interposed at said pivots at said second slots.
Claim 4
Dependent Claim
83 words
A skate comprising: a support frame; a carriage; means for slidably supporting said carriage on said support frame such that said carriage is positionable in a plurality of stable positions along a substantially vertical direction of the support frame; at least two wheels; means for rotatably supporting said at least two wheels on said carriage; thereby upon positioning of said carriage with respect to said support frame the at least two wheels both assume a relative position with respect to said support frame.
Claim 5
Dependent Claim
83 words
A skate comprising: a support frame; a carriage; means for slidably supporting said carriage on said support frame such that said carriage is positionable in a plurality of stable positions along a substantially vertical direction of the support frame; at least two wheels; means for rotatably supporting said at least two wheels on said carriage; thereby upon positioning of said carriage with respect to said support frame the at least two wheels both assume a relative position with respect to said support frame.
Claim 6
Dependent Claim
97 words
The skate of claim 3, wherein said carriage comprises a raised portion with an inclined plane which is inclined with respect to a horizontal plane of the support frame, the skate further comprising: a threaded screw which is rotatably supported by said support frame; and a slider element through which said threaded screw is screwed so that said slider is slidable in a direction parallel to the horizontal plane of the support frame, the slider element also comprising an inclined plane which is in sliding contact with said inclined plane of the raised portion of the carriage.
Claim 7
Dependent Claim
17 words
The skate of claim 4, further comprising biasing means for biasing said carriage in a vertical direction.
Claim 8
Dependent Claim
91 words
The skate of claim 4, wherein said support frame is C-shaped with a pair of wings between which said carriage is arranged, said carriage also comprising a pair of wings which extend substantially parallel to the wings of said support frame and between which said at least two wheels are rotatably supported, the carriage further comprising a pair of pivots which extend into a pair of vertical slots provided in the wings of said support frame, a pair of resilient members being arranged in said vertical slots and surrounding said pivots.
Claim 9
Dependent Claim
83 words
The skate of claim 4, wherein said support frame is C-shaped with a pair of wings between which said carriage is arranged, said carriage also comprising a pair of wings which extend substantially parallel to the wings of said support frame and between which said at least two wheels are rotatably supported, the skate further comprising a leaf spring having ends which are connected to the wings of said support frame and a middle portion connected to said raised portion of the carriage.
Claim 10
Dependent Claim
28 words
The skate of claim 4, further comprising a pair of springs which extend in a vertical direction and which are interconnected between said support frame and said carriage.
