Adjustable gripper for male sexual stimulation device

Abstract

An adjustable gripper mechanism for male masturbation devices that allows for adjustment in gripper diameter based on individual variations in the girth of penises or based on individual preferences regarding tightness. In a preferred embodiment, the adjustable gripper mechanism comprises a left tubular portion, a right tubular portion, a hinge connecting the two tubular portions on one side of the tubular shape, a screw connecting the two tubular portions on the other side of the tubular shape, and a screw adjustment mechanism allowing for adjustment of the diameter of the tubular shape by turning of the screw. In some embodiments, the screw adjustment mechanism may be motorized, such that the gripper diameter may be adjusted electronically.

What is claimed is: 
     
         1 . An adjustable gripper mechanism for male sexual stimulation devices, comprising:
 a tubular shape formed of rigid materials having a circumference and comprising a first tubular portion and a second tubular portion;   a screw connecting the two tubular portions at a first location about the tubular shape;   the first tubular portion further comprising a screw adjustment mechanism wherein operation of the screw adjustment mechanism in a first direction causes the screw to rotate clockwise and operation of the screw adjustment mechanism in a second direction causes the screw to rotate counterclockwise;   the second tubular portion having screw threads for receipt of the screw wherein rotation of the screw causes the first and second tubular portions either to be forced away from one another or forced toward one another, depending on the direction of rotation of the screw; and   a hinge connecting the two tubular portions at a second location about the circumference of the tubular shape.   
     
     
         2 . The mechanism of  claim 1 , wherein the screw adjustment mechanism is motorized via motor, servo, or actuator. 
     
     
         3 . The mechanism of  claim 1 , further comprising:
 a traveler formed of rigid materials having a means for receiving force from a linear motion driver and a means for guiding that force along a linear path; and   a bridge formed of rigid materials connecting the traveler with the adjustable gripper mechanism.   
     
     
         4 . The mechanism of  claim 3 , wherein the means for receiving force from a linear motion driver is a screw nut with screw threads that convert rotational movement of a screw into a linear motion. 
     
     
         5 . The mechanism of  claim 3 , wherein the means for guiding that force along a linear path is one or more guide rod sleeves configured to accept guide rods for stabilizing the linear movement of the traveler and preventing rotation of the traveler. 
     
     
         6 . An adjustable gripper mechanism for male sexual stimulation devices, comprising:
 a tubular shape formed of rigid materials having a circumference and comprising a first tubular portion and a second tubular portion;   a screw connecting the two tubular portions at a first location about the tubular shape;   the first tubular portion further comprising a screw adjustment mechanism having threads which engage with the screw wherein operation of the screw adjustment mechanism in a first direction draws the screw in a first direction and operation of the screw adjustment mechanism in a second direction pushes the screw in a second direction opposite to the first direction;   the second tubular portion having a means for attaching a portion of the screw in at a fixed location on the second tubular portion, whereby drawing of the screw in the first direction by the screw adjustment mechanism causes the first and second tubular portions to be forced away from one another, and pushing of the screw in the second direction by the screw adjustment mechanism causes the first and second tubular portions to be forced toward one another; and   a hinge connecting the two tubular portions at a second location about the circumference of the tubular shape.   
     
     
         7 . The mechanism of  claim 6 , wherein the screw adjustment mechanism is motorized via motor, servo, or actuator. 
     
     
         8 . The mechanism of  claim 6 , further comprising:
 a traveler formed of rigid materials having a means for receiving force from a linear motion driver and a means for guiding that force along a linear path; and   a bridge formed of rigid materials connecting the traveler with the adjustable gripper mechanism.   
     
     
         9 . The mechanism of  claim 8 , wherein the means for receiving force from a linear motion driver is a screw nut with screw threads that convert rotational movement of a screw into a linear motion. 
     
     
         10 . The mechanism of  claim 8 , wherein the means for guiding that force along a linear path is one or more guide rod sleeves configured to accept guide rods for stabilizing the linear movement of the traveler and preventing rotation of the traveler.
