Abstract
Abstract A snow skiing device enabling the use of a single snow ski to support both feet of a skier for Alpine snow skiing and especially slalom snow skiing, the device including means providing a limited universal and automatically releasable connection between one of the skier's boots and the ski at a position disposed rearwardly of the skier's other boot which may be retained by a conventional automatically releasable binding. The limited universal and automatically releasable connection may also be adjusted longitudinally of the ski to meet physical and various skiing requirements of the skier.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
In a ski device, the combination including a planar sole plate, an elongate toe stem connected to and projecting longitudinally forwardly from said sole plate, a ball fixed to the free end portion of said toe stem, a planar base plate, a support member comprised of a pair of support elements each connected to said base plate for pivotal movement about an axis normal to the plane of said base plate, said support elements defining a socket adapted to receive said ball, said ball and socket connecting said toe stem to said support member for limited universal movement relative thereto.
Claim 2
Dependent Claim
100 words
In a ski device, the combination including a planar sole plate, an elongate toe stem connected to and projecting longitudinally forwardly from said sole plate, a ball fixed to the free end portion of said toe stem, a planar base plate, a support member comprised of a pair of support elements each connected to said base plate for pivotal movement about an axis normal to the plane of said base plate, said support elements defining a socket adapted to receive said ball, said ball and socket connecting said toe stem to said support member for limited universal movement relative thereto.
Claim 3
Dependent Claim
39 words
The combination as set forth in claim 1, said toe stem projecting longitudinally from said sole plate and out of the plane of said sole plate whereby said ball is disposed out of the plane of said sole plate.
Claim 4
Dependent Claim
19 words
The combination as set forth in claim 1, and means threadably connecting said toe stem to said sole plate.
Claim 5
Dependent Claim
38 words
The combination as set forth in claim 1 including spring means resiliently restraining pivotal movement of said support elements relative to said base plate whereby said ball is releasably retained in the socket defined by said support elements.
Claim 6
Dependent Claim
