A hauler device is disclosed for transporting multiple items across the floor or upstairs with ease. The device is a hard plastic sled equipped with a long, rope-type or flexible handle to pull the sled across the ground or upstairs. The hauler device comprises a body component that is configured in a rectangular (i.e., rectilinear) shape as a sled. The body component is capable of holding multiple items to be transported across the floor or upstairs, such as groceries, retail items, etc. Attached to the body component is a long, cord-type or flexible handle used to pull the sled. Thus, once the body component of the device is loaded with items, a user can transport the items by pulling the handle of the sled in a convenient and less physically taxing manner.

The present invention provides a retractable wheel system for snowmobile skis. The retractable wheel system of the present invention may be installed on a snowmobile ski without affecting its structural integrity by installing the system on the reinforced portion of the snowmobile ski. When a user circulates in a path with little or no snow, the retractable wheel system is positioned in the extended configuration by the user and the system will automatically return to the retracted configuration when the user returns in a snowy zone. This is realized by using a pre-tensioned spring that will reposition the wheel in the retracted configuration. The spring transmits a rotational movement to the member on which the wheel is fixed.

A ski system for a bicycle including a bicycle having a front wheel and a rear wheel, a ski, and an attachment assembly attaching the ski to the wheels in the skied configuration. The attachment assembly includes a front binding and a rear binding attached to the ski for removably receiving the front wheel and the rear wheel, respectively, in the skied configuration. A front tension cord system and a rear tension cord system are couplable between the ski and the front wheel and rear wheel, respectively, in the skied configuration.

The vehicle includes: a chassis which includes a front cross-member and a rear cross-member; a nacelle receiving a person or a load, pivotally mounted relative to the central part of the cross-members about a substantially longitudinal hinge axis, the center of gravity of the nacelle being situated below said hinge axis; a front train and a rear train, each including two movement supports on the ground, each movement support being connected to the end part of the corresponding cross-member by a connecting system; the cross-members, situated in the upper part of the nacelle, being separate pieces linked together only by the nacelle, via the hinge axis, so as to be able to pivot about the hinge axis independently of one another.

Quick-release skis couple to the front wheels of an ATV or other wheeled vehicle, to permit the ATV to travel over snow. The rear ATV wheels may be left unaltered, or more commonly, tracks may be substituted for the rear wheels. The ski coupling includes a drive-on runner and coupling having in one embodiment width-adjustable side walls, an over-center clamp, and a lock for securing the over-center clamp. In a second embodiment, a pivotal tire cage allows the ATV tire to be driven onto the ski, but simply by forward travel of the tire the cage pivots to constrain the tire thereon. A strap then binds the tire and cage to ensure the tire stays in place on the ski. In a third embodiment, an ATV track is converted to a runner by the application and tensioning of a ski. Additional embodiments are illustrated.
