Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
An endless-belt traction snow vehicle comprising: a vehicle body; an endless-belt traction means driving said vehicle body; a ski or skis for directing the course; a vertically extensible leg member which corresponds to each of said skis and by which said ski is supported at the front bottom of the vehicle body; said vehicle body being provided with a hollow cylindrical supporting member disposed at the front portion thereof and corresponding to said leg member; said leg member being formed into a round bar slidably inserted into said supporting member; means for fixing said leg member to said vehicle body in a suitable length desired each time; and said fixing means consisting of a spring member for upwardly urging said leg member relative to said vehicle body, a spacer and a stop member or members combined with said spacer so as to allow the leg member to be adjusted to the vehicle body stepwise or steplessly in relation to the lengthwise direction of said leg member.
Claim 2
Dependent Claim
166 words
An endless-belt traction snow vehicle comprising: a vehicle body; an endless-belt traction means driving said vehicle body; a ski or skis for directing the course; a vertically extensible leg member which corresponds to each of said skis and by which said ski is supported at the front bottom of the vehicle body; said vehicle body being provided with a hollow cylindrical supporting member disposed at the front portion thereof and corresponding to said leg member; said leg member being formed into a round bar slidably inserted into said supporting member; means for fixing said leg member to said vehicle body in a suitable length desired each time; and said fixing means consisting of a spring member for upwardly urging said leg member relative to said vehicle body, a spacer and a stop member or members combined with said spacer so as to allow the leg member to be adjusted to the vehicle body stepwise or steplessly in relation to the lengthwise direction of said leg member.
Claim 3
Dependent Claim
71 words
An endless-belt traction snow vehicle claimed in claim 1 in which an operation member associated with a steering handle is connected with the upper end of the leg member, and the spring member is formed into a compressible coil positioned between the upper end of said supporting member and said operating member. 3. An endless-belt traction snow vehicle claimed in claim 1 in which the stop member is of pin type.
Claim 4
Dependent Claim
128 words
An endless-belt traction snow vehicle claimed in claim 1 in which said spacer is provided with a flat peripheral surface formed at the upper end adjacent to the lower end of said supporting member, and a peripheral surface formed at the lower end and provided with a group or groups of recesses arranged at different positions in the lengthwise direction of the leg member, and said stop member corresponding to each group of the recesses is mounted on the periphery of the leg member below the spacer, each of the recesses acting to maintain a desired distance between the stop member and the adjacent portion of the supporting member to the spacer against the urging action of the spring member due to its engagement with the stop member.
Claim 5
Dependent Claim
18 words
An endless-belt traction snow vehicle claimed in claim 4 in which the stop member is of pin type.
Claim 6
Dependent Claim
57 words
An endless-belt traction snow vehicle claimed in claim 4 in which the lower peripheral surface of the spacer irregularly undulates in part in the lengthwise direction of the cylinder thereby to form a plurality of concave portions differently spaced from the upper peripheral surface for engagement with the stop member, said concave portions defining the recesses respectively.
Claim 7
Dependent Claim
111 words
A snow vehicle comprising a vehicle body, an endless-belt traction means supporting an operable to drive said vehicle body, a ski disposed forwardly of said endless-belt traction means for directing the course of travel of said vehicle body, an extensiblE leg member having a lower end attached to said ski, a hollow cylindrical supporting member fixed to said vehicle body and slidably receiving said leg member, a spring interposed between said leg member and said hollow cylindrical member urging said leg member upwardly, an abutment on one of said members, and steps on the other of said members to selectively support said abutment to effect step adjustment of said leg member.
Claim 8
Dependent Claim
111 words
A snow vehicle comprising a vehicle body, an endless-belt traction means supporting an operable to drive said vehicle body, a ski disposed forwardly of said endless-belt traction means for directing the course of travel of said vehicle body, an extensiblE leg member having a lower end attached to said ski, a hollow cylindrical supporting member fixed to said vehicle body and slidably receiving said leg member, a spring interposed between said leg member and said hollow cylindrical member urging said leg member upwardly, an abutment on one of said members, and steps on the other of said members to selectively support said abutment to effect step adjustment of said leg member.
Claim 9
Dependent Claim
139 words
A snow vehicle characterized substantially in accordance with claim 7, including a tubular spacer affixed onto the lower end of said hollow cylindrical supporting member, said spacer being provided with a flat peripheral surface formed at the upper end adjacent to the lower end of said hollow cylindrical supporting member, and a peripheral surface formed at the lower end and provided with a number of recesses arranged at different positions in the lengthwise direction of said leg member, and said abutment corresponding to each of said recesses is mounted on the periphery of said leg member below said spacer, each of said recesses acting to maintain a desired distance between said abutment and the adjacent portion of said hollow cylindrical supporting member to the spacer against the urging action of said spring due to its engagement with said abutment.
