Abstract
A truck assembly for a skate-like device includes a truck support having a mounting plate and a mounting bracket extending angularly outward therefrom. A truck is pivotally mounted to the mounting bracket so as to define an axis of rotation at an acute angle to the mounting plate. Resilient means are positioned along the axis of rotation in engagement with the truck so as to resist rotation of the truck relative to the truck support. An adjustment pin extends through this assembly so as to increase or decrease the pressure of the engagement of the resilient means to the truck. In the preferred embodiment, the means comprise a cam insert and a cam follower in which the cam insert is keyed to the truck and the cam follower moves in a direction along the axis of rotation and against a resilient pad.
Claims11
A truck assembly for a skate-like device comprising:
- A. a truck support including a mounting plate and a mounting bracket extending angularly outward therefrom;
- B. a truck adapted to accomodate axled wheels and pivotally mounted to the mounting bracket so as to define a fixed axis of rotation at an acute angle to the mounting plate, said truck having a central aperture therethrough;
- C. means positioned along the axis of rotation and resiliently engaging said truck to resist rotation of the truck, said means including an annular insert positioned within the aperture of the truck and keyed thereto, said insert having at least one recessed cam surface, an annular cam follower extending into the insert and mating with the cam surface and a resilient pad positioned adjacent the cam follower whereby rotation of the truck and insert causes the follower to move along the cam surface in a direction along the axis of rotation and out of the insert, said movement being resisted by the pad;
- and
- D. an adjustment pin extending along the axis of rotation and through the bracket, the truck and the resisting means to increase or decrease the resilient engagement of the resisting means.

A truck assembly for a skate-like device comprising:
- A. a mounting plate adapted to connect the device;
- B. a spaced dual flanged bracket extending angularly outward from the plate, said flanges having aligned openings defining a fixed axis of rotation at an acute angle to the mounting plate;
- C. an apertured truck adapted to accommodate axled wheels and positioned between the flanges with its aperture in axial alignment with said openings, said truck adapted to rotate about the axis of rotation;
- D. an annular cam insert positioned within the aperture of the truck and keyed thereto, said insert having at least one cam surface;
- E. an annular cam follower positioned so as to extend into the annular insert and into mating relationship with the cam surface;
- F. a resilient annular pad positioned against the cam follower;
- and
- G. an adjustment pin extending through the flanges, truck, insert, follower and pad along the axis of rotation to adjust the pressure between the pad and cam follower;
- whereby rotation of the truck and cam insert causes the cam follower to move along the cam surface in a direction along the axis of rotation and out of the insert, said movement being resisted by the resilient pad.

A truck assembly for a skate-like device comprising:
- A. a truck support including a mounting plate and a mounting bracket having spaced flanges and extending angularly outward therefrom;
- B. a truck adapted to accommodate axled wheels and pivotally mounted to the mounting bracket between said flanges so as to define a fixed axis of rotation at an acute angle to the mounting plate, said truck having a central aperture therethrough;
- C. means positioned along the axis of rotation between said flanges and resiliently engaging said truck to resist rotation of the truck, said means including a truck insert having an annular rib extending normal to the axis of rotation to divide the insert into a first and second chamber, a first resilient annular pad positioned in the first chamber against the rib and a second resilient annular pad positioned in the second chamber against the rib and means engaging said pads to increase or decrease the pressure against the rib and the respective chamber;
- and
- D. an adjustment pin extending along the axis of rotation and through the flanges, the truck and the resisting means to adjust the pressure of the pad engaging means.
