Abstract
Abstract An apparatus to be used for displacing a snowmobile, the apparatus being formed of a platform mounted on swivelling wheels and provided at one end with braking shoes to avoid rolling of the platform when the snowmobile comes down from the platform on its own power. The apparatus is also preferably provided with a s semi-rigid strip at the other end of the platform to be used by the snowmobile to climb thereon, always under its own power, without the platform moving away from the snowmobile.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
280 words
An apparatus to displace a snowmobile having steering skis at the front and a driving endless track at the rear, the track extending centrally longitudinally of the snowmobile, said apparatus comprising: a. a platform mounted on swivelling wheels whereby to be displaced in all direction, said platform having a rearward part for the climbing thereon of the snowmobile and a forward part for the dismounting thereof; b. braking means at the forward end of said platform and across the path of the snowmobile, said braking means comprising a vertically movable member capable of being depressed under the weight of the snowmobile through the endless track thereof to apply a pressure on the ground in order to lock said platform and prevent that it moves away when the snowmobile dismounts; c. said platform having a length such as to fully receive the snowmobile without the latter reaching said forward part and actuating said braking means, whereby said apparatus may be freely displaced; d. wherein said braking means comprises: the said movable member formed as a plate mounted beneath the platform at the forward part thereof, said plate having at least one rib, on the upper face thereof, extending transversely to the direction of movement of the snowmobile, said rib passing freely through an opening formed across said platform and having a height such as to protrude and extend beyond the upper surface of said platform; resilient means biasing said plate against said platform, and at least one braking shoe mounted beneath said plate and adapted to be applied against the ground when the endless track of the snowmobile presses on said rib during displacement of the snowmobile toward said said part.
Claim 2
Independent Claim
280 words
An apparatus to displace a snowmobile having steering skis at the front and a driving endless track at the rear, the track extending centrally longitudinally of the snowmobile, said apparatus comprising: a. a platform mounted on swivelling wheels whereby to be displaced in all direction, said platform having a rearward part for the climbing thereon of the snowmobile and a forward part for the dismounting thereof; b. braking means at the forward end of said platform and across the path of the snowmobile, said braking means comprising a vertically movable member capable of being depressed under the weight of the snowmobile through the endless track thereof to apply a pressure on the ground in order to lock said platform and prevent that it moves away when the snowmobile dismounts; c. said platform having a length such as to fully receive the snowmobile without the latter reaching said forward part and actuating said braking means, whereby said apparatus may be freely displaced; d. wherein said braking means comprises: the said movable member formed as a plate mounted beneath the platform at the forward part thereof, said plate having at least one rib, on the upper face thereof, extending transversely to the direction of movement of the snowmobile, said rib passing freely through an opening formed across said platform and having a height such as to protrude and extend beyond the upper surface of said platform; resilient means biasing said plate against said platform, and at least one braking shoe mounted beneath said plate and adapted to be applied against the ground when the endless track of the snowmobile presses on said rib during displacement of the snowmobile toward said said part.
Claim 3
Dependent Claim
34 words
An apparatus as claimed claim 1 wherein said plate extends beyond said forward part and serves as landing platform for the snowmobile and is provided forwardly with a braking shoe applicable on the ground.
Claim 4
Dependent Claim
51 words
An apparatus as claimed in claim 1 wherein said resilient means comprises bolts secured to said platform on either side of said opening; said bolts extending freely across said plate and springs surrounding said bolts and respectively applied against the undersurface of said plate and against the heads of said bolts.
Claim 5
Dependent Claim
47 words
An apparatus as claimed in claim 1 wherein said platform is T-shaped of which the crossbar forms said forward part and the stem the rearward part; a transversely corrugated strip of semi-rigid material secured to said forward part to act as a loading platform for the snowmobile.
Claim 6
Independent Claim
242 words
An apparatus to displace a snowmobile having steering skis at the front and a driving endless track at the rear, the track extending centrally longitudinally of the snowmobile, said apparatus comprising: a. a platform mounted on swivelling wheels whereby to be displaced in all directions, said platform having a rearward part for the climbing thereon of the snowmobile and a forward part for the dismounting thereof; b. braking means at the forward end of said platform and across the path of the snowmobile said braking means comprising a vertically movable member capable of being depressed under the weight of the snowmobile through the endless track thereof to apply a pressure on the ground in order to lock said platform and prevent that it moves away when the snowmobile dismounts; c. said platform having a length such as to fully receive the snowmobile without reaching said forward part and actuating said braking means, whereby said apparatus may be freely displaced, and d. wherein said braking means comprises: said movable member in the form of a pair of locking bolts extending freely across said forward part and each having a head at each end to prevent removal from said platform and a spring between the upper heAd of each bolt and the upper surface of said platform; said bolts having a length sufficient for the lower head to be applied against the ground upon being depressed by the snowmobile when the latter moves forward.
Claim 7
Independent Claim
242 words
An apparatus to displace a snowmobile having steering skis at the front and a driving endless track at the rear, the track extending centrally longitudinally of the snowmobile, said apparatus comprising: a. a platform mounted on swivelling wheels whereby to be displaced in all directions, said platform having a rearward part for the climbing thereon of the snowmobile and a forward part for the dismounting thereof; b. braking means at the forward end of said platform and across the path of the snowmobile said braking means comprising a vertically movable member capable of being depressed under the weight of the snowmobile through the endless track thereof to apply a pressure on the ground in order to lock said platform and prevent that it moves away when the snowmobile dismounts; c. said platform having a length such as to fully receive the snowmobile without reaching said forward part and actuating said braking means, whereby said apparatus may be freely displaced, and d. wherein said braking means comprises: said movable member in the form of a pair of locking bolts extending freely across said forward part and each having a head at each end to prevent removal from said platform and a spring between the upper heAd of each bolt and the upper surface of said platform; said bolts having a length sufficient for the lower head to be applied against the ground upon being depressed by the snowmobile when the latter moves forward.
Claim 8
Dependent Claim
63 words
An apparatus as claimed in claim 5 further comprising a second platform pivotally mounted at one end beneath the first platform and having a portion thereof projecting ahead of said forward part so as to serve as landing platform, and resilient means to hold said second platform in raised position against the first platform when the snowmobile endless track does not bear thereon.
Claim 9
Dependent Claim
47 words
An apparatus as claimed in claim 5 wherein said first platform is T-shaped of which the crossbar forms said forward part and the stem the rearward part; transversely corrugated strip of semi-rigid material secured to said forward part to act as a loading platform for the snowmobile.
