Claim 8

An adjustable length, self biasing skate, comprising: a first beam structure; a second beam structure telescopically mounted in said first beam structure; independent sizing means slidably mounted in said second beam structure for movement between a first position inward of said second beam structure and a second position outward relative to said first position in said second beam structure, said sizing means comprising an elongated structure having a first end and a second end, said first end having a plurality of openings in it; latch means movably mounted to said first beam structure, said latch means including a part releasably engagable with selective ones of said opening plurality of said sizing means, engagement of said latch means with said sizing means establishing a stop preventing inward movement of said first and said second beam structures; and a spring operatively connected between said second end of said sizing means and said second beam structure, said spring biased to draw said sizing means inwardly of said second beam structure when said first and said second beam structures are drawn outwardly relative to one another with said sizing means engaged.

Claim 9

The skate of claim 6 wherein said first beam structure includes a top and a bottom, said first beam structure having a forward platform attached to it along said top and said bottom having said latching means attached thereto.

Claim 10

The skate of claim 7 wherein said second beam structure includes a top and a bottom, said second beam structure having a rearward platform attached to it along said top, said sizing means being slidably mounted along a channel formed in said second beam structure.

Claim 11

The skate of claim 8 wherein said channel of said second beam structure has a stop formed in it, and said sizing means includes an edge with a notch formed in it, said notch being engagable releasably with said stop to limit movement of said sizing means at said second position.

Claim 12

The skate of claim 9 wherein said spRing is operatively connected between said second end of said sizing means and said rearward platform-second beam structure combination.

Claim 13

The skate of claim 10 further characterized by a side wall extending upwardly from said rearward platform, said side wall having an opening in it for engaging a portion of shoe heel whenever a shoe is inserted in said skate.

Claim 14

An adjustable length, self biasing skate, comprising: a forward platform including a toe engaging part attached thereto, a depending beam structure integrally formed therewith and an axle mounting extending downwardly from said platform; a rearward platform including heel securing means attached thereto, a depending beam structure integrally formed therewith and an axle mounting extending downwardly therefrom, said rearward beam structure being telescopically engagable with said forward beam structure; independent sizing means slidably mounted in said beam structure of said rearward platform between at least a first inward position and a second outward position relative to said last mentioned beam structure, said sizing means comprising an elongated structure having first and second ends, said first end having a plurality of openings in it; latch means movably mounted to said beam structure of said forward platform, said latch means including a part releasably engagable with selective ones of said opening plurality of said sizing means to define a plurality of discrete longitudinal lengths for said skate, engagement of said latch means with said sizing means establishing a stop which prevents inward movement of said forward platform and said rearward platform; and a spring operatively connected between said rearward platform and said second end of said sizing means, said spring biased to draw said sizing means inwardly of said beam structure of said rearward platform when said rearward platform and said forward platform are drawn outwardly relative to one another with said latch means engaged.

Claim 15

An adjustable length, self biasing skate, comprising: a forward platform including a toe engaging part attached thereto, a depending beam structure integrally formed therewith and an axle mounting extending downwardly from said platform; a rearward platform including heel securing means attached thereto, a depending beam structure integrally formed therewith and an axle mounting extending downwardly therefrom, said rearward beam structure being telescopically engagable with said forward beam structure; independent sizing means slidably mounted in said beam structure of said rearward platform between at least a first inward position and a second outward position relative to said last mentioned beam structure, said sizing means comprising an elongated structure having first and second ends, said first end having a plurality of openings in it; latch means movably mounted to said beam structure of said forward platform, said latch means including a part releasably engagable with selective ones of said opening plurality of said sizing means to define a plurality of discrete longitudinal lengths for said skate, engagement of said latch means with said sizing means establishing a stop which prevents inward movement of said forward platform and said rearward platform; and a spring operatively connected between said rearward platform and said second end of said sizing means, said spring biased to draw said sizing means inwardly of said beam structure of said rearward platform when said rearward platform and said forward platform are drawn outwardly relative to one another with said latch means engaged.
