Abstract: Mounting clamps for coupling an accessory to a structure are disclosed. The mounting clamp includes a body configured to engage the accessory and to receive a portion of the structure, a jaw and an actuator. The jaw has a first member pivotally to the body by a first pivot that is selectively moveable, and a second member pivotally connected to the first member by a second pivot. When the first pivot is in a first position, the mounting clamp is in a first configuration adapted for clamping to a first portion of a first structure. When the first pivot is in a second position, the mounting clamp is in a second configuration adapted for clamping to a second portion of a second structure. The jaw, which is selectively adjustable between open and closed positions, is configured to clamp one of the first and second portions when in the closed position.

Abstract: A tensioner for adjusting a tension in an endless track of a track system is disclosed. The tensioner includes a resilient portion and a wheel connecting portion. The resilient portion is connectable to a frame of the track system, the resilient portion being oriented generally vertically. The wheel connecting portion is pivotally connectable to the frame of the track system, is connected to the resilient portion and is configured to connect to an idler wheel assembly. A track system having the tensioner is also disclosed.

Abstract: A modular frame for a track system is disclosed. The modular frame includes an upper frame member operatively connectable to an axle of a vehicle and removably connectable to a first lower frame member. The first lower frame member is configured to connect with at least one of a support wheel assembly and an idler wheel assembly, and connection of the upper frame member to the first lower frame member confers a first lower frame member-specific function to the track system. Another modular frame, track systems having the modular frames, tensioners and track systems having the tensioners are also disclosed.

Abstract: A deformable wheel is disclosed. The deformable wheel includes a hub, at least one resilient member connected to the hub, and a plurality of circumferentially positioned rim portions connected to the at least one resilient member, where each one of the plurality of rim portions is moveable relative to the hub about the at least one resilient member. A track system including the deformable wheel is also disclosed.
