TECHNICAL FIELD
The present disclosure relates to sexual stimulation devices and, more specifically, to a reciprocating sexual stimulation device.
DISCUSSION OF THE RELATED ART
Sexual stimulation devices, sometimes known as sex toys or adult toys, are designed to produce a range of different motions such as vibrating, rotating and thrusting. Thrusting motions may be generated by the action of reciprocating in which an element may move forward and backward in a line. Since such devices generally use an electric motor that is capable of producing rotational movement, reciprocating action may be produced by such mechanical elements as cams, that convert the rotational motion of the motor into reciprocating motion, or push rods mounted to a rotating disk or wheel driven to push and pull the rod generally along the reciprocating direction.
However, such existing approaches for providing reciprocating action may be poorly suited for use within sexual stimulation devices owing to inefficiencies in power utilization, the need for awkward device shaping to accommodate the needed mechanical elements, limited stroke length, weak drive force for portable arrangements, an asymmetrical ascending and descending stroke force.
SUMMARY
A reciprocating stimulation device comprises a handle portion and a stimulation body disposed over the handle portion. The stimulation body includes a stimulation component arranged at a tip thereof. The reciprocating stimulation device further comprises a first drive assembly and a second drive assembly. The first drive assembly has a first motor configured to drive the stimulation body in a reciprocating motion. The second drive assembly has a second motor configured to drive the stimulation component in a thrusting motion.

A cylindrical portion 2151 of the crescent-shaped guide pin 215 is rotatably secured with the annular top cover 216 fit on the top surface of the sleeve 221 as it is rotatably secured, and the annular top cover 216 fitting the top surface of the sleeve 221 creates a first opening 217 disposed within the first nut component 214, with the arcuate portion 2152 of the crescent-shaped guide pin 215 extending into the first opening 217. The first opening 217 of the first nut component 214 may also be passed through by the first screw 212, and the arcuate portion 2152 may fit into a dual-helical groove 218 of the first screw 212.
In at least some exemplary embodiments, reference to the FIGS. 3-6, and 11-12, the center of the first screw 212 may have a first cavity 219 open to the bottom of the first screw, the first torque receiving structure 213 may be a non-cylindrical post that transitionally fits into the first cavity 219, and the first screw 212 may be rotated within the first nut component 214 by the first torque receiving structure 213 being actuated by the first motor 211, causing the first screw 212 is free to move up and down as the first motor 211 rotates, resulting in the first screw 212 being able to drive the stimulation body 200 in reciprocating motion relative to the handle portion 100. In one embodiment, the first screw 212 rotatably coupled to the stimulation body 200 via a first bearing 225 that connects a top portion of the first screw 212 to a loaded member 222 of the stimulation body 200 to counteract torque generated on the stimulation body 200 during rotational movement of the first screw 212.
In at least some exemplary embodiments, reference to the FIGS. 7-12, the second drive assembly 310 may include a second screw rotatably coupled to the stimulation assembly 300 (e.g., the second screw may be replaced with a cylindrical cam 312), which may be rotatably coupled to the thrusting member 322. the second drive assembly 310 may also include a second torque receiving structure 313 and a second nut component 314.
In at least some exemplary embodiments, reference to the FIGS. 7-12 and 15, the second nut component 314 may be formed by at least a portion of the support member 321, and a longitudinal force structure (e.g., a columnar guiding pin 315) arranged on the top surface of the support member 321, and an annular top cover 316 arranged on the top surface of the support member 321. A fixed end of the columnar guiding pin 315 can be secured as the annular top cover 216 fills the bracket member 321. The fixed end of the column guide pin 315 can be secured as the annular top cover 216 fits over the top surface of the support member 321, and the annular top cover 316, when it fits over the top surface of the support member 321, forms a second opening 317 disposed within the second nut component 314, and the free end of the column guide pin 315 extends into the second opening 317. The second opening 317 of the second nut component 314 may also be traversed by a cylindrical cam 312, and the cylindrical guide pin 315 may fit into a milled groove 318 of the cylindrical cam 312.
In at least some exemplary embodiments, reference to the FIGS. 7-12, the center of the cylindrical cam 312 may have a second cavity 319 open to the bottom of the cylindrical cam 312, the second torque receiving structure 313 may be a non-cylindrical that transitionally fits into the second cavity 319, and the cylindrical cam 312 may be rotated within the second nut component 314 via the second torque receiving structure 313 that may be actuated by the second motor 311, causing the cylindrical cam 312 is free to move up and down as the second motor 211 rotates, resulting in the cylindrical cam 312 being able to drive the thrusting component 300 in a thrust movement relative to the handle portion 100. In one embodiment, the cylindrical cam 312 is rotatably coupled to the stimulation component 300 via a second bearing 325 that connects an upper portion of the cylindrical cam 312 to the thrust component 322 of the stimulation component 300 to counteract torque generated on the stimulation body 200 during rotational movement of the first screw 212. As the second screw is replaced with a cylindrical cam 312, and due to the milled groove 318 has a shorter stroke, resulting in a thrust movement stroke of the stimulation component 300 of from about 3 millimeters to about 15 millimeters, and a thrust frequency of the stimulation assembly 300 of from 1,000 to 3,000 thrusts per minute.
In at least some exemplary embodiments, reference to the FIGS. 3-6 and 12, the device 10 may further include a sensing stopper component spaced apart at the first drive assembly 210, a sensing element, and a controller. In one embodiment, the sensing stopper assembly may be a Hall sensor 800, which may be mounted on the outer side of the sleeve 221. In one embodiment, the sensing element may be a magnet (not shown in the figures), which is mounted on a mounting hole 226 in the sidewall of the cartridge loaded member 222, allowing the magnet to follow the linear motion of the stimulation body 200. In one embodiment, the controller (not shown in the figure) may be soldered to the circuit board 600, electrically connected to the Hall sensor 800 via a conductive structure. The controller receives a signal generated when the magnet enters the sensing range of the Hall sensor 800 and generates a reversal signal or a braking signal that causes the first motor 211 to reverse or brake. In one embodiment, the stimulation body 200 may perform reversed linear motion or braked linear motion in response to the reversal signal or braking signal.
In at least some exemplary embodiments, reference to the FIG. 7-12, the electrically conductive structure may include wires (not all of which are shown in the figure) that enable electrical connection between the battery 500, the circuit board 600, the first motor 210, and the Hall sensor 800. In one embodiment, the electrical connection between the battery 500 and the second motor 310 can be a spring-shaped pipe line 900, which may be arranged on elongate curved slots 2210 on each side of the sleeve 221. The spring-shaped pipe line 900 is periodically stretched and restored as the second motor 310 is driven by the first drive assembly 210 in a reciprocating motion.
In at least some exemplary embodiments, reference to the FIGS. 13-15, a reciprocating stimulation device 10 utilizing a dual-helical grooved screw 124 in accordance with exemplary embodiments of the present invention. Here an inner sleeve 136 may be disposed over the rotating motor 107. The inner sleeve 136 may include a linear guiding hole 134. The screw 124 may also be disposed within the inner sleeve 136. The screw 124 is mated to the rotating motor 107 such that the rotating motor 107 spins the screw 124. The screw 124 has a dual-helical groove 131 in its surface that may include an ascending helical groove and a descending helical groove (i.e., levorotatory helical groove and a dextrorotatory helical groove). The two helical grooves are interlaced with one another and are connected end-to-end at both the top and bottom of the screw 124.
A nut is formed by the lower cover 133 and the upper cover 129 which come together with the guide pin 132. The guide pin 132 protrudes from the linear guide hole 134 of the inner sleeve 136. Thus, as the rotating motor 107 rotates, the nut formed by the lower cover 133 and the upper cover 129 move up or down depending on which of the two helical grooves the guide pin 132 is presently disposed within as the nut is prevented from rotation by the disposition of a bump within the linear guiding hole 134. As discussed above, the direction of travel of the nut changes as the guide pin 132 reaches either the top or bottom of the screw 124 and then passes to the other groove.
It is to be understood that the nut arrangement may include more than one guide pin 132, for example, it may include a pair of bumps disposed at opposite sides of the nut and these bumps may each be seated with a different linear guide hole 134 of the inner sleeve 136 and so there might be two linear guide holes 134 on opposite sides of the inner sleeve 136 to correspond to the pair of bumps. This may provide added stability over an embodiment in which there is only one bump being used.
An outer sleeve 126 is coupled to the nut formed by the lower cover 133 and the upper cover 129 by the placement of one or more mounts 128A and 128B. Thus, as the nut moves up and down, it carries the outer sleeve 126 up and down along with it. A support 127 is coupled to the outer sleeve 126 and a case 125 is coupled to the support 127 and in this way, the case 125 of the device 100 may achieve the desired reciprocating motion.
Power may be conducted from the base of the device to the top of the device, for example, to power a vibrational motor or other stimulation component disposed therein, by a pair of conductive strips 135A and 135B that may be disposed around the inner sleeve 136. Each of the conductive strips 135A and 135B may be electrically connected to a wire at its bottom that connects to the power source and a wire at its top that connects to the vibrational motor or other stimulation component. By using conductive strips in this manner, friction may be reduced between the inner sleeve 136, that remains stationary relative to the base, and the outer sleeve 126, that moves up and down relative to the base, as using wires between these two sleeves might well interfere with the reciprocating movement.
FIG. 14 is a cutaway view of the reciprocating stimulation device 10 shown in FIG. 13. The device 100 is illustrated here in its fully retracted state where the outer sleeve 126 is disposed around the inner sleeve 136. Here, the handle portion 108 encases the shell 117, the power source/battery 110, the rotating motor 107, and the PCB 118 with controller disposed thereon. The charging ports 120 and the buttons 111A/111B may protrude from the shell 117 and handle portion 108.
The handle portion 108 is again bridged with the stimulation body 102, on the exterior, by the stretchable tube 106. Within the inner sleeve 136, the screw 124 with its dual-helical grooves is coupled to the rotating motor 107. The lower cover 133 comes together with the upper cover 129 to form the nut that engages with the grooves 131 of the screw 124, for example, with the guide pin 132. A pair of mounts 128A and 128B fix the nut assembly, including the lower cover 133, the upper cover 129, and the guide pin 132, to the outer sleeve 126. The outer sleeve 126 is coupled to the stimulation body 102 and above the outer sleeve 126, and within the stimulation body 102, is the support 127. A chamber 139 may run through the support 127 and wires may run within the chamber 139, emerge through a first hole 138 in the case 125 so as to power the vibrating motor 137 disposed within the top of the stimulation body 102.
In the various figures, many of the same elements are shown in multiple figures but are not described again with respect to each and every figure in which they appear. Accordingly, it is to be assumed that to the extent that an element is not described with respect to one figure, it is at least similar to a corresponding element shown and described with respect to another figure. Like reference numerals may represent like elements throughout the specification and the figures.
Exemplary embodiments described herein are illustrative, and many variations can be introduced without departing from the spirit of the disclosure or from the scope of the appended claims. For example, elements and/or features of different exemplary embodiments may be combined with each other and/or substituted for each other within the scope of this disclosure and appended claims.
