Convertible sled

Claim 1

A convertible sled comprising an elongated seat; two longitudinally spaced-apart supports rigidly secured to the underside of said seat; a pair of laterally spaced-apart runners rigidly secured in turn to the lower portions of said supports; a plate extending vertically and downwardly from the front of said seat; a first rod extending through and journalled in a hole provided therefor in said plate at its front end and also extending through and journalled in another hole provided therefor in the frontmost support at its rear end; a second and a third rod each rotatably secured at either end to the lower portion of said supports on either side of said sled adjacent said runners, said three rods extending longitudinally of said seat; further comprising a front wheel carried by the said first rod and a pair of rear wheels carried by the corresponding second and third rod respectively; each wheel rotatable about its axis, the latter being transverse to the long axis of the associated rod, a linkage means operatively connecting said first rod to said second and third rods whereby rotation of said first rod causes rotation of said second and third rods through an equal angle; an operating lever integrally attached to the frontmost portion of said first rod; whereby said operating lever can be moved from a first operative position wherein said three wheels are vertically oriented and in contact with the surface over which the sled is travelling, extending slightly below the plane defined by said runners, and a second inoperative position wherein said three wheels are horizontally oriented and retracted upwardly from the plane defined by said runners.
