Abstract
Abstract A mechanical interlock for securing either ice skates or roller skates to a single base member. The base member has surfaces for receiving the foot of the user and the interlock includes a pair of upstanding studs disposed at one end of the skate which cooperate with recesses in the base plate. An elongated leaf spring is secured to each skate at one axial extremity for pivotal motion in a plane parallel to the plane of the base plate. Disposed on the other axial extremity of the spring is a pair of fingers disposed for snug fitting engagement with the top and bottom respectively of the base plate and the skate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
161 words
A skate assembly comprising: means for receiving the foot of a user, said means for receiving including a first elongated generally planar horizontal member having two apertures disposed at one end thereof, said apertures being elongated with a first longitudinal portion thereof being smaller than a second longitudinal portion, a skate member having ground engaging means, said skate member including a clamp carried on an elongated arm, said elongated arm being carried for pivotal motion around a generally vertical axis on said skate member, said clamp including a pair of horizontally extending fingers, said skate member including a second generally planar horizontal member having two upstanding studs with heads thereof larger than the body thereof, said heads being dimensioned and positioned to pass freely through said first portion of said elongated apertures and not to pass freely through said second portion thereof, said clamp being selectively pivotable for clamping engagement of said first and second generally planar members between said fingers.
Claim 2
Dependent Claim
161 words
A skate assembly comprising: means for receiving the foot of a user, said means for receiving including a first elongated generally planar horizontal member having two apertures disposed at one end thereof, said apertures being elongated with a first longitudinal portion thereof being smaller than a second longitudinal portion, a skate member having ground engaging means, said skate member including a clamp carried on an elongated arm, said elongated arm being carried for pivotal motion around a generally vertical axis on said skate member, said clamp including a pair of horizontally extending fingers, said skate member including a second generally planar horizontal member having two upstanding studs with heads thereof larger than the body thereof, said heads being dimensioned and positioned to pass freely through said first portion of said elongated apertures and not to pass freely through said second portion thereof, said clamp being selectively pivotable for clamping engagement of said first and second generally planar members between said fingers.
Claim 3
Dependent Claim
15 words
The apparatus as described in claim 1 wherein said fingers are manufactured of spring steel.
Claim 4
Dependent Claim
32 words
The apparatus as described in claim 2 wherein said apertures are elongated in a direction which is aligned with respect to the direction of elongation of said first and generally planar member.
Claim 5
Dependent Claim
48 words
The apparatus as described in claim 3 wherein said generally vertical axis is established by cylinder and said first elongated generally planar member has an aperture disposed for snug fitting engagement with said cylinder with said means for receiving the foot and said skate member in engaged relationship.
