A sex toy comprising a body housing a motor; a shaft coupled to the motor; a massaging member mounted over the shaft; and a controller coupled to control the motor to drive the massaging member in a reciprocating motion along the length of the shaft is described. The reciprocating motion results in a change in length of the sex toy. The change in length may comprise about 20 mms to about 100 mms; about 25 mm to about 90 mm; or about 30 mm to about 85 mm. One full stroke of the reciprocating motion may be performed in about 0.5 to about 2.0 about seconds; about 0.6 to about 1.5 seconds; or about 0.7 to about 1.0 seconds.

Description

FIELD OF THE INVENTION

The present invention relates to sex toys, adult toys or internal massagers, such as thrusting vibrators, and in particular, motorised sex toys, adult toys or internal massagers that perform a reciprocating motion.

BACKGROUND TO THE INVENTION

There are a large number of sex toys available on the market. Some sex toys include movement to provide increased stimulation to the user. For example, internal massagers may provide movements within the body and thrusting vibrators or dildos may perform a reciprocating motion to mimic thrusting of a penis.

Some devices, such as thrusting vibrators or dildos, in the prior art provide reciprocating movement of a bump beneath an outer material of the device to mimic the thrusting of a penis. One problem with such devices is that they do not provide a true or realistic thrusting sensation to the user of the device, because only the bump moves up and down.

Other thrusting vibrators or dildos provide reciprocating movement of the vibrator or dildo. However, this movement typically involves a single repetitive thrusting distance, and therefore is somewhat unrealistic and provides limited enjoyment to the user. Also, a large portion of the device is usually occupied by the motor and the power supply.

The movement of thrusting vibrators and dildos in the prior art is also typically inaccurate and the movement may stick or jam when under load.

The reference to any prior art in this specification is not, and should not be taken as, an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.

OBJECT OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention relate to sex toys, adult toys or internal massagers, such as thrusting vibrators, and in particular motorised sex toys, adult toys or internal massagers that perform a reciprocating motion.

FIG. 1 shows a sex toy 100 according to a preferred embodiment of the present invention. The sex toy 100 comprises a body 110 housing a motor 120. A shaft 130 is coupled to the motor 120, and a massaging member 140 is mounted over the shaft 130. A controller 150 is coupled to control the motor 120 to drive the massaging member 140 in a reciprocating motion along the length of the shaft 130. The controller 150 can comprise a plurality of selectable programs to control the extension and/or a vibration of the sex toy 100. The controller can be, for example, an integrated circuit, a chip, a processor, a logic circuit or another device capable of controlling the motor in a selectable manner.

In the embodiment shown, the shaft 130 is coupled to the motor 120 via a gear box 125. A power supply 155 is provided within the body. The power supply 155 is coupled to power the motor 120. The power supply 155 can be, for example, a battery. In some embodiments, the sex toy 100 uses an external power source, for example, to charge the battery or power the sex toy 100. The charging may be via a USB connection, induction or may make use of replaceable batteries.

In the embodiment shown, the massaging member 140 is mounted to a traveller 160 that is in engagement with the shaft 130. The traveller 160 can be, for example, annular or saddle shaped. The traveller 160 is designed to interchangeably mount massaging members 140 having different sizes and/or shapes and/or surface textures. The traveller 160 comprises a head 162 that extends over a distal end of the shaft. The head 162 includes a vibrator 164 adjacent a distal end of the massaging member 140. Vibrator 164 is shown to be housed partly within head 162 and to extend partly outside of head 162. The head 162 receives the massaging member 140 as a sleeve. Bellows 166 couple the massaging member 140 to the body 110. The bellows 166 expand when the massaging member 140 is extended.

The extension of the massaging member is of significant advantage over other isometric devices which do not provide a stroke or stroke type action. By providing a sex toy 100 that increases in length a more realistic sensation is provided.

The extension of the massaging member may be to a plurality of predetermined extension positions. FIG. 2 is a schematic diagram showing an example of extension positions of the sex toy 100 of FIG. 1. Four predetermined extension positions are shown, being an origin 0, a first extension position 1, a second extension position 2 and a third extension position 3. The traveller 160 is shown at the third extension position 3. The movement of traveller 160 from the origin 0 to the third extension position 3 amounts to one stroke.

The sex toy 100 may comprise one or more sensors 170 coupled to the controller 150 to determine the extension position along the shaft 130. As shown in FIG. 2, one or more sensors 170 can be provided on the body 110 and/or on the traveller 160.

In one embodiment, the controller 150 reverses the direction of the motor 120 at one or more of the plurality of predetermined extension positions to drive the massaging member 140 in the reciprocating motion.

FIGS. 3 and 4 show the engagement of the traveller 160 with the shaft 130. The traveller 160 is in engagement with the shaft 130 via a shoe 180 that is slidably mounted in a groove 132 of the shaft 130. In the embodiment shown, the groove 132 is a continuous groove formed of a left-hand helical groove and a right-hand helical groove connected to one another at either end. However, in other embodiments the groove can be a single helical groove or another appropriate groove configuration. Preferably, a pitch of the groove 132, and/or a configuration of the gear box 125, achieves a maximum torque at the traveller 160 for the motor 120.

The shoe 180 is coupled to the traveller 160 via a pin or screw 182. A guide 136 is provided between the shaft 130 and the traveller 160. The guide 136 comprises a slot 138 within head 162, the slot 138 extending along the shaft 130 to maintain an angular position of the shoe 180 relative to the shaft 130 while permitting movement of the shoe 180 along the shaft 130. When the motor 120 turns the shaft 130, the shoe 180 is held at a fixed angular position by guide 136, and the helical groove 132 of the shaft 130 slides over the shoe 180 moving the shoe 180, and hence the traveller 160 up or down the shaft 130, and consequently moving head 162 to lengthen or shorten toy 100, according to the direction of rotation of the shaft 130.

The shoe 180 comprises a shoe head 184 slidably mounted in the groove 132. The shoe head 184 has a length that is greater than a width of the groove 132, which maintains an orientation of the shoe head 184 relative to the groove 132 and prevents the shoe head 184 from switching between the left-hand helical groove and the right-hand helical groove where the grooves intersect along the shaft 130. The shoe 180 has an arcuate edge 186 facing and contacting the shaft 130. The arcuate edge 186 complements the cross sectional shape of the shaft 130. The shoe head 184 also comprises forward arcuate outer edge 188 and reverse arcuate outer edge 189 to conform to the outer edge of the groove 132.

One or more corners and/or sides of the shoe 180 are rounded and/or tapered adjacent the sides of the groove 132 to reduce sticking or jamming of the shoe 180, particularly under load. The rounded and/or tapered shape of the corner and/or side is accentuated on a leading corner or side by provision of arcuate outer edge 188 on the shoe 180 to further reduce the friction or drag. For example, the leading corner and/or side 188 can be rounded and/or tapered in such a way that the friction or drag from the sides of the groove 132 can be minimized, in particular, at the top and bottom of the groove 132 where higher friction may occur as the gradient of the groove 132 changes and the shoe 180 transitions between the left-hand helical groove and the right-hand helical groove. An opposing corner and/or side can be rounded and/or tapered in a similar way by provision of arcuate outer edge 189 to minimize friction when the shaft 130 is rotated in the opposite direction by the motor 120, for example, when the sex toy 100 is driven in shorter thrusts to the first extension position 1 or the second extension position 2.

FIG. 4A shows another embodiment of traveller 160 in which shoe head 184 comprises a length approximately equal to one half the circumference of the shaft. By extending the length of shoe head 184, the inventor has found that improved stability of motion is achieved.

FIG. 5 shows the shaft 130 and the groove 132 according to one embodiment. The groove 132 is a continuous groove formed of a left-hand helical groove and a right-hand helical groove connected to one another at either end. The continuous groove enables the shaft 130 to be rotated in a single direction and the shoe 180 to transition between the right-hand helical groove and left-hand helical groove to change a direction of movement of the traveller 160 along the shaft 130, for example, at the point where the massaging member 140 reaches a maximum or minimum extension. The curvature of the curved section 134 at one or both ends of the groove 132 is selected to provide a smooth change of direction for the traveller 160. The curvature of the curved section 134 can also be selected to increase or decrease the acceleration in the change of direction.

FIGS. 6 and 6A show the gear box 125 according to one embodiment. The gear box 125 comprises a first fillet ring 210, a second fillet ring 220, a third fillet ring 230 and a cylindrical casing 240. The second fillet ring 220 supports three planetary gears 222 of a first epicyclic gear train. The third fillet ring 230 supports three planetary gears 232 of a second epicyclic gear train. The cylindrical casing 240 comprises an internal gear 242 in engagement with the planetary gears 222, 232 to connect the epicyclic gear trains. The gears are supported on the fillet rings 220, 230 via spindle tines 224, 234.

The first fillet ring 210 forms an end of the cylindrical casing 240 adjacent the motor 120. A drive shaft 200 of the motor 120 is received through an aperture 212 in the first fillet ring 210 and a sun gear 205 of the first epicyclic gear train is coupled to the drive shaft 200.

The third fillet ring 230 forms an end of the cylindrical casing 240 adjacent the shaft 130. A pin 250 of the shaft is received through an aperture 232 in the third fillet ring 230 and a sun gear 255 of the second epicyclic gear train is coupled to the pin 250.

A gear ratio of the gears in the gear box 125 is configured such that the torque is increased from the motor 120 at the shaft 130.

FIG. 7 shows a sex toy 100 according to another embodiment. In this embodiment, the body 110 is coupled to or forms part of an ergonomic handle. One ergonomic advantage is provided by the body 110 having a longitudinal axis 111 that is not aligned with the direction of extension of the massaging member 140. The longitudinal axis 111 of the body 110, for example, provides a more comfortable angle of grip for the user. The sex toy 100 is controlled by one or more user controls 112, for example buttons, on the sex toy 100. The longitudinal axis 111 of the body 110 is at an angle to the direction of extension such that the controls are visible to the user during use. For example, as shown in FIG. 7, the controls 112 are located on a face of the body 110 that substantially faces the direction of extension and therefore can be clearly viewed by the user. The controls can be used to select a program from the plurality of selectable programs, for example, to control an extension and/or a vibration of the sex toy 100.

The controls allow the speed of the reciprocating motion to be set. In one embodiment the speed may be set to one of three speeds.

Of significant advantage is the provision of a twist and click ring 168 on the massaging member 140 or the head 162 for securing the massaging member 140 or the head 162 to the traveller 160. In other embodiments, the massaging member 140 may attach to the traveller 160 via a screw thread or other known attachment means. This ready detachability simplifies cleaning and means different massaging members 140 may be attached. These different massaging members 140 may comprise different shapes; different functionalities such as, different lengths of extension and/or different vibration capabilities.

FIG. 8 shows a system 300 according to one aspect of the invention. The system 300 comprises the controller 150 coupled to control the motor 120 to drive the massaging member 140 in a reciprocating motion to a plurality of predetermined extension positions along the length of the shaft 130. The power supply 155 is coupled to power the controller 150 and the motor. One or more user controls 112 are coupled to control the controller 150, for example, to select the plurality of selectable programs. One or more indicators 330, such as light emitting diodes (LEDs), can be coupled to the controller 150 and, for example, provided on the body 110 to indicate the current program or setting of the device. The controller 150 is also coupled to a communications device 154 to enable wireless control of the sex toy 100. For example, the communications device 154 can be a Wi-Fi and/or a Bluetooth transceiver. Wireless control can be provided via a computing device 310, for example, a smart phone, a notebook or a desktop computer. The wireless control may be provided directly or over a communications network 320, such as, the internet.

FIG. 8A shows the user controls 112 according to one embodiment. The user controls 112 include a power button 114 to power on/off the sex toy 100, and a decrease button 117 and an increase button 118 to decrease or increase respectively the level of vibrations or speed/extension of the traveller 160. The user controls 112 also include a vibration select button 115 to set the decrease and increase buttons 117, 118 to control vibrations, and a motor select button 116 to set the decrease and increase buttons 117, 118 to control the speed/extension of the traveller 160.

FIG. 8B shows the indicators 330 according to one embodiment. A power indicator 332 is provided to show when the sex toy 100 is turned on, a vibration indicator 334 is provided to show when vibrations are active, and a moving motor indicator 336 is provided to show the motor 120 is active.

FIG. 9 shows another embodiment of the sex toy 100 including one or more support rods 137 along which the traveller 160 travels. The one or more support rods 137 extend along the length of the shaft 130, through the traveller 160 and provide additional sturdiness to the traveller 160, particularly under load.
