## Background
FIELD OF THE DISCLOSURE
The present disclosure relates generally to vehicles, and in particular to bicycles which are equipped to travel upon snow or ice.
BACKGROUND OF INVENTION
Ice skating is an activity that may be enjoyed by individuals of all ages. However, this activity requires a certain amount of practice and skill to partake in. Further, an individual's available practice time is often limited to the cold winter months for proper ice conditions. This makes it difficult for an individual to master the skill of ice skating. Ice skating can be unsafe as it requires balance and coordination to prevent falling down, which may prevent certain individuals from partaking in the activity (e.g. elderly) due to the risk of injury.
It is an object of the present invention to provide a vehicle for travel upon snow or ice that is easy to use and safe for individuals of all ages.

DETAILED DESCRIPTION OF THE DISCLOSURE
FIGS. 1-21 illustrate an exemplary system 1 according to an embodiment of the present application. As shown in FIG. 1, the system can generally include a vehicle frame 10, a support structure 20, a weight compensation system 30, a traction apparatus 40, and a steering apparatus 50.
With reference to FIGS. 1-3, the support structure 20 can be used to attach the vehicle frame 10 to one or more runners 22. The runners 22 may be laterally offset relative to the longitudinal direction of the frame 10 to provide lateral stability to an operator of the system in use. This can be advantageous for operating the system on low-frictional surfaces such as ice or snow. The runners 22 can also help maintain a particular bearing on such surfaces. The runners 22 may be embodied as skates, skis, wheels, or the like.
The support structure 20 may be defined by a perimeter frame 24. The perimeter frame 24 can partially or completely surround the vehicle (e.g. a bicycle). In the depicted example, the perimeter frame 24 can define an unbroken perimeter about the vehicle frame 10 (e.g. a bicycle frame). Such a perimeter frame 24 can serve to protect the system or user from obstacles incurred during use. The perimeter frame 24 may also be advantageous in protecting others from the system, which may include sharp blades or other, potentially dangerous or hazardous, features. The perimeter frame 24 can be potentially equipped with additional safety features, such as padding about the perimeter of the perimeter frame 24. The support structure 20 can include a step 26 for allowing a user to mount and dismount from a seat of the system. The step 26 may include apertures to provide a high-friction surface, and to also to deter the buildup of ice, snow, or the like.
The weight compensation system 30 may be configured to compensate for a user's weight on the vehicle frame 10 during use of the system 1. For example, the weight compensation system 30 can be configured to allow users of varying weights gain consistent traction on a surface having a low coefficient of friction. Specifically, the weight compensation system 30 can be useful in assisting relatively lighter users to obtain traction via the traction apparatus 40 (e.g. a tread, tire, studded tire, etc.) on a surface having a low coefficient of friction. The weight compensation system 30 may also assist in decreasing the amount of weight placed on the traction apparatus 40 by a user that is relatively heavy.
With reference to FIGS. 4-8, the weight compensation system 30 can be embodied as a pivotable arrangement, including a slidable frame 32 (FIG. 4) and a pivot 34 (FIG. 6). The slidable frame 32 can include an outer frame 32a that is connected to the support structure 20 and an inner frame 32b that is connected to the traction apparatus 40. The inner frame 32b and outer frame 32a may be translatable relative to one another. In one particular example, the inner frame 32b may slide along a track formed by the outer frame 32a. In this manner, the inner frame 32b can slide along longitudinally relative to the outer frame 32a. The outer frame 32a and the inner frame 32b may slide between a rest position and a maximum position. For example, in the rest position, the inner frame 32b can be slid a minimum distance relative to outer frame 32a, for example, when no load is applied to the vehicle frame 10. In the maximum position, the inner frame 32b may be slid a maximum distance away from the outer frame 32a, for instance, when a relatively heavy, or maximum load, is applied to the outer frame 32a. Stops can be provided on the outer frame 32a to prevent the inner frame 32b from sliding beyond the rest position or the maximum position. As the frames 32a, 32b slide relative to one another, the vehicle frame 10 will pivot about the pivot 34. In this manner, the user's weight on the traction apparatus 40 will cause the frames 32a, 32b to slide relative one another to compensate for heavier or lighter users of the device.
The weight compensation system 30 can be configured to direct the user's weight to the traction apparatus 40, rather than both the support structure 20 and the vehicle frame 10. In this manner, the user's weight can be applied to the traction apparatus 40 to gain traction on a low-friction surface—which can be particularly useful for users of relatively low-weight. Because a user having relatively high-weight may gain too much traction, the weight compensation system 30 may reduce the amount of weight applied to the traction apparatus 40. For example, the maximum position of the outer frame 32a and the inner frame 32b may be selected such that the load of a relatively high-weight individual may be directed toward the support structure 20, rather than the traction apparatus 40. The weight compensation system can also include various biasing mechanisms that are configured to compensate for users having various weights. For example, a spring bias may be used to urge the inner frame 32b away from the maximum position in order to further reduce the amount of the user's weight that is applied to the traction apparatus. Similarly, a spring bias may be used to urge the inner frame 32a toward the maximum position in order to increase the force applied to traction apparatus 40.
As shown in the detail views of FIGS. 6-8, the pivot 34 can be located adjacent the connection point between the support structure 20 and the vehicle frame 10. The connection point can be removably attachable to the vehicle frame 10 to allow for the system described herein to accept various vehicle frames 10. FIGS. 15-21 depict an alternative embodiment, which To further facilitate the acceptance of various size and shaped vehicle frames 10, the support structure 20 may include a vertical support 28 (FIG. 6) that is adjustable in height. For example, the vertical support 28 can include a sliding portion to adjust the overall length of the vertical support 28. A bolt, pin, or the like can be used to make the adjustments to the overall length of the vertical support 28.
Alternative embodiments of the weight compensation system are possible. For example, the weight compensation system can include a rear tread that is independently movable relative to portions of the vehicle frame. This can be achieved, for example, via a traction apparatus that translates relative to portions of the vehicle frame and/or support structure to compensate for a user's weight.
FIGS. 15-21 refer to an exemplary system generally described herein. Referring to FIG. 16, vertical member 28 is depicted to include a sliding portion to adjust the overall length. The length of vertical member 28 may be adjusted to receive various sizes of vehicle frames 10.
Referring to FIG. 18, inner frame 32b has a height A. In a specific embodiment, the height A is 19.25 inches. Referring to FIG. 19, the outer frame 32a has an interior width B. In a specific embodiment, the interior width B is 7.75 inches. The inner frame 32b has an exterior width C. In a specific embodiment, the exterior width C is 7.625 inches. The clearance between outer frame 32a and inner frame 32b allows inner frame 32b to slide relative to outer frame 32a. Referring to FIG. 20, the perimeter frame 24 has an overall length D and an overall width E. In a specific embodiment, the overall length D is 64.5 inches and the overall width E is 24 inches.
The present invention provides a vehicle for travel upon snow or ice that is easy to use. Since the vehicle frame and operation resemble that of a standard bicycle, an individual may not need extensive practice to effectively use. The vehicle of the present invention is further safe for individuals for all ages to use. Since the vehicle has a steady support structure, the risk of the individual falling and injuring themselves is reduced. The vehicle of the present invention further provides a similar travelling experience for individuals of various weights. Since the weight compensation system adjusts the position of the traction apparatus diverts the applied load from the support structure, it allows users of varying weights to gain consistent traction on a surface having a low coefficient of friction.
Although the present disclosure has been described with respect to one or more particular embodiments, it will be understood that other embodiments of the present disclosure may be made without departing from the spirit and scope of the present disclosure. Hence, the present disclosure is deemed limited only by the appended claims and the reasonable interpretation thereof.
