Abstract
The volleyball service device of this invention includes; a base member for supporting the structure; a support member attached to the base member extending upwardly from the base member and forming an angle with the base member to extend increasingly over the center of gravity of the base member; a server head for propelling volleyballs forward; and a trolley attached to the server head to vertically reposition the server head relative to the support member. In a preferred embodiment the volleyballs are propelled forward by a plurality of rotating wheels.
Claims14
A volleyball service device comprising:
- a base member;
- a support member attached to the base member extending upwardly from the base member and forming an angle with the base member to extend increasingly over the center of gravity of the base member;
- a server head for propelling volleyballs forward, supported by the support member;
- and
- a means attached to the server head to vertically reposition the server head relative to the support member.

A practice volleyball service apparatus comprising:
- a base member;
- a volleyball server head comprising;
- a mounting frame;
- at least one driven rotating wheel having a first driving surface, a first axis of rotation and a first plane of rotation attached to the mounting frame;
- a second wheel having a second driving surface, a second axis of rotation, and a second plane of rotation attached to the mounting frame, wherein the first plane of rotation and the second plane of rotation are substantially the same, and the first axis of rotation and the second axis of rotation are offset enough to allow a sphere the approximate size of a volleyball to contact the first driving surface of the first wheel and the second driving surface of the second wheel simultaneously;
- and
- a feeding station suitably mounted on the mounting frame to allow placing volleyballs in wheel accessible position thereby allowing the driven rotating wheel and the second wheel to propel the volleyballs forward in the direction of volleyball travel;
- a support having the frame vertically rotatably and horizontally rotatably attached thereto;
- and
- means for vertically repositioning the volleyball server head attached to the base and to the volleyball server head comprising;
- a support inclined away from the direction of volleyball travel and inclined over the base member;
- a bracket means for holding the volleyball server head vertically repositionable on the support mounted thereto;
- and
- a resilient means attached to the base member disposed in parallel orientation to the support, the resilient means allowing the support to maintain a selected vertical position and the support frame positioning the server nearer the center of the base member as the server is repositioned farther from the base member.
