RECIPROCATING STIMULATION DEVICE

摘要

A mechanized sexual stimulation device is provided that provides a reciprocating stimulation body, preferably emulating a male in function with various length of penetration possible. Designs herein allow the protruding dildo to move back and forth to a variety of length, speeds and angles while flexing in many directions. The device includes a housing with a ball reverse screw rotatably mounted to the housing, and a reversing nut which retains bearing balls that allow the nut to move linearly up and down the ball reverse screw as the screw is turned in a single direction, thereby moving a reciprocating stimulation body such as a dildo connected (indirectly or directly) to the reversing nut. Channel or groove structures on the ball reverse screw and reversing nut guide the reciprocating back and forth stoke in a linear motion.

主权项

1. A sexual stimulation device including:
a housing; a ball reverse screw rotatably mounted in the housing and having a first proximal end with a torque receiving structure for applying torque to the ball reverse screw from a motor; a reversing nut adapted to hold one or more bearing balls that roll in grooves on the screw, the reversing nut adapted to move linearly up and down the screw as the screw is turned in a single direction; a reciprocating stimulation body carried by the movement of the reversing nut.
