| A sled construction consists of a generally concave sled which conforms to the buttocks of the sledder and a strap assembly for releasably securing the sled to the body of the sledder. A body portion of the concave sled includes an inner contoured surface which is received in conforming relation with the buttocks of a sledder and a outer surface having longitudinal runners extending downwardly therefrom. The sides of the body portion taper inwardly and curve upwardly to form symmetrical triangular wing portions which extend around the hips of the sledder. The front of the body portion tapers inwardly and curves upwardly to form an apex received adjacent to the crotch of the sledder. A substantially planar flange portion extends outwardly from the back of the body portion so that it is received adjacent a waist of the sledder. The body portion includes a lateral slot adjacent to the apex and the flange portion includes two symmetrically spaced slots therein. The strap assembly includes a strap which is threaded through the slots so as to extend around the legs and waist of the sledder. Fastening device releasably fasten opposite ends of the strap together and provides for adjustment of the length of the strap. | ||||||
| 162 | Ice block sled | US437731 | 1989-11-16 | US5181741A | 1993-01-26 | Lawrence S. Sheiman; Jonathan C. Sheiman |
| An improved sled for recreational use. The sled comprises a support member which is formed in the shape of a seat to accommodate a rider in an upright position. The support member has handholds at either edge for the rider to grasp. A block of ice is coupled to the bottom side of the support member. The ice is held in place by an adjustable retention member. The retention member is made up of two support blocks which are rigidly attached to the support member. A compression block is adjustably connected to each of the support blocks by means of a locking screw disposed through the support blocks. As the screw is turned, the compression blocks move inwardly clamping the ice. In alternative embodiments of the retention member, the locking screws are replaced by springs which automatically force the support blocks inward and pieces of flexible foam rubber are used to hold the ice block in place. | ||||||
| 163 | Hauling device for leaves and other materials | US625742 | 1990-12-11 | US5104133A | 1992-04-14 | David Reiner |
| A hauling device for leaves, litter, and other materials such as stone, earth, mulch, manure and tree stumps comprises a tarpaulin with flexible support members and a rope including a unique assembly whereby the operator may secure and haul the collected material by pulling a loop of the rope. The tarpaulin is fitted with flexible support members within hems along the rear side edge and along a portion of each side edge. The rope ends are attached to the tarpaulin at both sides and threaded through the apertures of hardware located at both front and rear corners, thus providing a loop along the front side to be grasped either by the operator or a mechanical device such as a tractor. Once material is collected on the surface of the tarpaulin, the operator pulls the loop and thereby harnesses the rear and side edges, flexes the support members, and in unison confines the collected material. As the operator continues to pull the loop, obstructions on the rope arrest the confining action to provide a towline for the operator to haul the device along the ground to another location. To unload the material, the operator releases the loop and grasps the device along the rear side and rolls out the material over the front side. After the device is free of material, the operator gives the device a shake which retracts the rope and provides the device in a flat state to position for another load of material. | ||||||

| An improved sled provides a support member having an ice block removably coupled to its underside. The ice block is coupled to the support member by an adjustable retention means. A pair of support blocks are connected to the underside of the support member and have threaded holes disposed therethrough. Locking screws are placed through each of the holes, and are coupled to compression blocks. As the locking screws are turned, the compression blocks move inwardly, thereby gripping the ice block. As the ice melts, the locking screws can be tightened, so as to maintain a firm grip on the ice. In the preferred embodiment, the support member is formed in the shape of a seat. | ||||||

| 167 | Water and snow wishbone shaped sled for one or two | US806423 | 1985-12-09 | US4678445A | 1987-07-07 | F. Javier Monreal |
| This is a sporting wishbone or Y-shaped board for supporting one or two riders in sliding over water or snow. The single bottom arm of the Y is as wide as the combined width of the two front arms of the Y plus the space in between, or approximately 16" to 18", being the total length of the sled 5' to 6'. The medial edges of the two front arms have a built up lip that gently starts from zero at their front tips and slowly becomes 3" to 4" tall near the crotch of the Y-shaped sled. At the very crotch, this built up lip is humped up 14" off the flat bed of the sled to form a racing bicycle seat-like cusp. The widest, single arm of the Y, smoothly curves upward towards the end of the sled forming a gentle letter S in longitudinal section, being the end of this curved up elevation approximately 14" over the flat bed of the sled. Symmetrical sets of fixed, soft straps are placed at various points to hold the rider's feet in the different positions possible for one or two riders for facing either opposite end of the sled. A small, downward pointing stabilizing fin is provided below the wide section. | ||||||
| 168 | Recreational sled | US496597 | 1983-05-20 | US4666171A | 1987-05-19 | David Sellers |
| A recreational snow sled comprises an elongated molded plastic shell having a longitudinal central rib forming a U-shaped bottom channel of gradually increasing depth toward the rear of the sled. The sled is designed to carry a person seated in a kneeling position straddling the hump formed by the central channel. The rider is restrained at the knees by a strap running across the forward gunwales of the shell. When the sled is sliding downhill, the central channel tends to form a ridge of packed snow enhancing axial stability and maneuverability. The angle of attack may be controlled by leaning backwards so that the front of the sled is tilted up by the knee strap. | ||||||

| 172 | Toboggan | US74491 | 1979-09-11 | US4256319A | 1981-03-17 | Richard D. Winter |
| A snow toboggan, or a flat bottomed sled, has a body with a curved forward portion. At its aft end, the sled is outfitted with a pair of hinged drag panels, each hinged independently to the body of the sled. On the underside of each panel is disposed one or more spikes which are capable of digging into the snow. Also on the underside of the body near its aft end is fixed a longitudinally oriented fin which is used to stabilize the forward motion of the sled. On the underside of the curved portion of the body is pivotably supported a pair of front stabilizing fins which are used to stabilize the sled when the sled is travelling across a hill or traversing a hill, to prevent the forward end from sliding down the hill. When not needed, these front stabilizing fins are rotated up out of the snow so that sharp turns can be maneuvered. Sharp turns are obtained by lowering one panel at a time by suitable means mounted in the body to allow the spikes thereunder to grip into the snow. If both panels are lowered into the snow, the toboggan can stop or slow down. Suitable means are included to connect the panel to a respective foot-operated pedal disposed near the forward portion of the sled. | ||||||
