ABSTRACT:
BACKGROUND OF THE INVENTION
This invention is related to a dolly useful for storing a snowmobile, and more particularly to a snowmobile dolly for supporting the track of the snowmobile in a raised position.
Snowmobile dollies are used for storing snowmobiles when they are not in use. Some prior art snowmobile dollies have been disclosed in U.S. Pat. No. 5,632,498 issued May 27, 1997, to Ernie Beaudet and Mark A. Lamberty for “Snowmobile Dolly System”; U.S. Pat. No. 4,288,087 issued Sep. 8, 1981 to Robert I. Morrison for “Simplified Snowmobile Support Dolly”; and U.S. Pat. No. 3,777,829 issued Dec. 11, 1973 to Arthur L. Rogers for “Snowmobile Wheel Support Combination”.
Typically, such prior art dollies support the skis on a wheeled support. The rear track is supported either on a separate wheeled support or on the ground. It is desirable to store a snowmobile in a position such that the weight of the snowmobile does not rest on the track, while still providing means for easily maneuvering the snowmobile into a compact storage location, such as in a garage or the like.
SUMMARY OF THE INVENTION
The broad purpose of the present invention is to provide an improved snowmobile dolly comprising a frame having forward caster supporting the skis and a rear post supporting the track in a suspended position. The post is removable so that the rear end of the dolly frame can be inserted under the snowmobile, between the skis to a position behind the snowmobile's rear bumper. The snowmobile is raised and the bumper connected to the upper end of the post.
Still further objects and advantages of the invention will become readily apparent to those skilled in the art to which the invention pertains upon reference to the following detailed description.
