March 20, 1962 A. GUERARD SKI SLED Filed Sept. 12, 1960 ZZIU/Zf' .da/wie GURAAI 3,9%,120 Patented Mar. 20, 1962 3,026,120 SKI SLED Achle Guerard, 126 Duiuth W., Montreal, Quebec, Canada Filed Sept. 12, 1960, Ser. No. 55,288 Caims. (Cl. 289-12) The present invention relates to a novel snow-going vehicle which is related to sleds and skis.

The closest known Vehicle of this type consists of a single ski having a seat supported at about two feet above the ski. This type of Vehicle is practically irnpossible to steer.

The Vehicle of this invention can attain great speeds and enables the operator to sit on it and to steer it as easily as conventional skis and even make complete loops, the steen'ng being effected by body movements of the operator.

=In the annexed drawings:

FIGURE 1 is a perspective view;

FIGURE 2 is a bottom plan view;

FIGURE 3 is a section along line 3-3 of FIGURE 1;

FIGURE 4 is a section along line 4--4 of FIGURE 1;

FIGURE 5 is a partial section taken along line 5-5 of FIGURE 2; and

FIGURE 6 is a section along line 6-6 of FIGURE 2.

:'n the drawings, like numerals indicate like elements.

The Vehicle comprises a ski 1 of conventional length and shape and on which is secured a seat 2 having lateral skates 3 On each side of ski 1. The ski 1 has an upturned front end 5 and a central longitudinal groove 6. The central portion of the ski 1 is provided with metal ski edges 7 of T-shaped cross section and protruding from bottom face 8 of ski 1.

The seat 2 has an ovoidal shape with the narrower end forwardly directed. The seat 2 is dished with inclined sides and its center is directly secured to ski 1 by screws 9.

A Vertical central web 10 disposed between the ski 1 an seat 2 rigidly secures .the seat to the ski.

Skates 3 are secured underneath and to seat 2 symmetrically with respect to ski 1.

Each skate 3 has a first part 11 and a second part 12 forming a Y, the first part being straight and defining one branch and the leg of the Y and the second part being straight and meeting the first part to form the other branch of the Y. Parts 11 are incli ned with respect to ski 1 and diverge forwardly whereby their front parts 11' are more spaced from ski 1 than their rear parts 11".

The bottom edge of each part 11 has a metal edge 13 and is upwardly inclined at front and rear parts 11' and 11" respectively while it is horizontal in central part 11'.

The parts 11 are secured at right angles to seat 2 and are therefore vertically inclined and downwardly diverging when the Vehicle is upright that is when the transverse axis of the ski is horizontal.

The parts 11 of skates 3 are normally out of contact with the ground but eflect a Change of direction When the Vehicle is tilted sideways by a lateral displacement of the operator's center of gravity. The change of direction corresponds to the angle between parts 11 and ski 1.

Parts 12 serve to turn the Vehicle continuously. These parts converge forwardly of the Vehicle and are upwardly recessed relative to parts 11 because they are disposed exteriorly of parts 11. They have metal edges 14.

Part 12 comes into contact with the ground upon further lateral tilting of the seat. Under these conditions, parts 11 and 12 form an angular ground engaging edge which produces continuous turning of the Vehicle whereby the latter can make several loops if desired.

The seat 2 has a size sumcient for receiving the body and legs of the operator in order to prevent accideuts. Seat 2 has handles 15.

The operator being seated has a minimum wind resistance and can attain great speeds when sliding down a snow covered hill.

While a preferred embodiment of the invention has been illustrated and described, it is understood that modifications can be efiected without departing from the spirit and scope of the -appended claims.

What I claim is:

1. A ski-sled comprising a ski, a seat secured to said ski, and skates secured to and underneath said seat on each side of said ski, said skates being inclined with respect to said ski and upwardly spaced from the plane of the ground engaging face of said ski whereby in the upright position of the ski and seat said skates are out of contact with the ground and selectively contact the ground upon lateral tilting of the ski and seat to effect a change of direction of the ski-sled, each skate consisting of a first straight part forwardly diverging with respect to the ski and a second straight part disposed laterally outwardly of said first part, inclined with respect to the latter and meeting the same intermediate its ends.

2. A ski-sled as in claim 1 wherein said second parts are upwardly recessed with respect to said first parts whereby they require greater tilting than for said first parts to come into ground engagement.

3. A ski-sled as in claim 2 wherein said seat has a dish shape with inclined sides, said skates being secured to said sides and disposed in planes Vertically inclined relative to the Vertical central plane passing through said ski.

4. A ski-sled as in claim 3 wherein said ski and skates have the ground engaging faces lined with metal edges.

5. A ski as claimed in claim 2 wherein said first skate parts have upwardly inclined front and rear bottom edge portions and said second parts have their bottom edge upwardly recessed from the central bottom edge portion of said first part.
