FIELD OF THE INVENTION
The present invention relates to a pair of mechanic stands designed to support a snowmobile in a stable position on its side for repair and maintenance.
BACKGROUND OF THE INVENTION
A snowmobile is a recreational vehicle designed for use on snow or ice. The basic components of a snowmobile or snowmachine or sled, as it is sometimes called, are an engine, a moveable track, and a pair of skis. A user will manipulate the skis using a steering mechanism to orient the snowmobile in the desired direction. The engine powers the track and is typically controlled by a hand operated throttle.
As with all mechanical devices, the operation and ownership of a snowmobile requires routine maintenance and repair. Currently, to repair the underside of a snowmobile, including the track, suspension, studs mounted onto the track, and other accessible and repairable components on the underside of the snowmobile, the snowmobile is lifted vertically. The two common methods of lifting are through the use of a hydraulic jack or using a winch, pulley, and rope attached to the bumper.
Although these devices allow a user to perform maintenance on their snowmobile, they do have several drawbacks. First, to perform maintenance a user is required to work underneath the device with the weight of the device suspended above them. Second, lighting may be a challenge as the overhead position of the snowmobile prevents overhead and natural light from reaching the view of the user. Third, these devices require a significant amount of set up time and space to ensure they operate safely and appropriately. Therefore, there is a need for a device that is easier to use, prevents a user from having to work from underneath the snowmobile, and allows for more access to artificial and natural light on the work surface.
SUMMARY OF THE INVENTION
The present invention provides an improved snowmobile maintenance support device that quickly and safely supports a snowmobile for maintenance and repair. This system utilizes the existing skis of the snowmobile and contains a pair of stands that securely attach to a snowmobile and support the snowmobile on its edge with the track oriented perpendicular to the floor, easily allowing a user to work on the underside of the snowmobile. Each stand has its own features and attaches to a different part of the snowmobile.
A first stand attaches to the bumper and extends a length perpendicular to the length of the snowmobile to support the rear of the snowmobile. The first stand has a top end and a bottom end. The bottom end includes a means to adjust the height of the first stand and a base connected to the height adjustment means. The base creates a stable and solid surface to support the snowmobile and includes an edge. The edge is arcuate shaped to allow the snowmobile to be easily tipped onto and off of its side.
The first top end includes a notch to securely engage the edge of the bumper of the snowmobile. A moveable support is adjustable along the length of the first stand to engage the second edge of the bumper opposite the notch. The moveable support is designed to secure to the stand using friction, pressure, or a mechanical screw that securely engages the stand. The moveable support may include a handle and a securing means to secure the support at a desired position after it is engaged with the bumper.
A second stand attaches to the steering post of the snowmobile parallel to and orientated to the first stand to provide support for the middle of the snowmobile. The second stand has a top end and a bottom end. The top end includes an attachment portion, a lip, and a retaining pin. The bottom end includes a base to support the weight of the snowmobile. The base includes an edge. The edge is arcuate shaped to allow the snowmobile to be easily tipped onto and off of its side.
The attachment portion is narrowed in diameter relative to the second stand to allow for insertion into the steering post of the snowmobile. The lip represents a transition from the narrow end and supports and prevents the steering post from sliding down the second stand when the snowmobile is tipped onto its edge for maintenance. The retaining pin is affixed to the top end of the second stand to ensure the stand is secured within the steering post.
The second stand may include a bracket attachable to the top end to secure a snowmobile that does not have a hollow steering post to allow for insertion of the attachment portion. Preferably, this bracket is removably connected to the attachment end and secures to the handlebars of the snowmobile. This bracket increases the versatility of the device and allows it to be particularly useful for the repair of older snowmobiles.
The height adjustment means allows the user to extend the length of the first stand to accommodate varying widths of the rear end and bumper configurations of a given snowmobile relative to the height of the second stand. Adjustability is necessary to ensure that the system is universal across a wide range of makes, models, and years of snowmobiles. Adjustability is also necessary to allow a user to safely use the device in creating a stable and level working surface; therefore, the first stand and second stand bases and the snowmobile skis are required to be aligned for proper use of the device.
In the preferred embodiment, the height adjustment means is a threaded rod connected to the base and received within the stand. This rod can then easily be moved by twisting the base. Although a threaded rod is preferred due to its ease of use and strength, other similar adjustment means such as a second rod telescopically received within the first rod and secured using a pin, a detent received within a hole, a sliding and latching mechanism, or other similar mechanical stop may be used.
In the preferred embodiment of the present invention, the first stand and second stand are constructed out of steel due to its strength and overall material properties. Although steel is preferred, other metals may be used. The length of the first stand and second stand, measured from the base to the top end, is critical to allow for the device to be universally applicable to several different types, models, manufacturers, and styles of snowmobiles. Based upon experimentation and measurements, the preferred length of the first stand and the second stand from the base to top end is a range between twenty-four inches (24′′) and thirty-four inches (34′′). Although this is the preferred range, the device can be utilized in several additional lengths, with the only limitation the height of the snowmobile with the ski on its edge.
In use, a user will affix the first stand and the second stand to the snowmobile requiring maintenance. The user will make all of the necessary adjustments to secure the stands to the snowmobile and ensure they are properly aligned. This may require the user to adjust the length of the stands by lowering the base and moving the moveable support of the first stand to secure the rear portion of the snowmobile. After the stands are affixed to the device, the user will tip the snowmobile onto its side where the snowmobile will be supported by the bases and the ski of the snowmobile. The user is then able to easily work on the underside of the snowmobile. After work is completed, the user simply rocks the snowmobile back to its normal position and removes the stands.
