DETAILED DESCRIPTION

(1) The invention will now be described with reference to the accompanying drawing, in which:

(2) FIG. 1 schematically shows an exploded perspective view of a dildo assembly in accordance with an embodiment of the present invention;

(3) FIG. 2 schematically shows a cross-sectional view of the dildo assembly of FIG. 1;

(4) FIG. 3 schematically shows a cross-sectional view of the first housing section of the dildo assembly of FIG. 1;

(5) FIG. 4 schematically shows a cross-sectional view of the second housing section of the dildo assembly of FIG. 1; and

(6) FIG. 5 schematically shows a side view of a dildo assembly in accordance with a further embodiment of the present invention.

(7) FIG. 1 schematically shows an exploded perspective view of a dildo assembly in accordance with an embodiment of the present invention. The dildo assembly comprises a switch cover 1, a printed circuit board (PCB) 2, a first housing section 3, a dildo 4, an electric motor 5, a worm gear 6, a main cog 7, three intermediate cogs 8, a worm wheel 9, a housing insert 10, a controller 11, a pulley wheel 12, a battery 13 and a second housing section 14. When assembled, the first and second housing sections 3, 14 combine to form a housing.

(8) The method of operation is as follows:

(9) Initially, the dildo 4 is in the flaccid state, i.e. wherein the dildo curves towards the housing, such that the tip of the dildo 4 is proximate the housing. Two switches are located on the switch cover 1. These switches are connected to first and second electronic switches on the PCB 2, underneath the switch cover 1. A first electronic switch is operable to activate the dildo 4, extending it from the flaccid state to an erect state. The first electronic switch is also operable to deactivate the dildo 4, returning it from the erect state to the flaccid state.

(10) When a user presses the first switch on the switch cover 1, the associated electronic switch on the PCB 2 is operated. This causes current to flow from the battery 13 to the electric motor 5, via the controller 11 along a plurality of wires (not shown).

(11) Once activated, the electric motor 5 rotates the worm gear 6, which is attached to an output shaft of the electric motor 5, in a first direction. The rotational force provided by the electric motor 5 is shifted through 90 through the interaction of the worm gear 6 with the worm wheel 9. The rotational force is then transmitted through the three intermediate cogs 8 to the main cog 7. Each of the intermediate cogs 8 are arranged to form a reduction gear system, i.e. as the rotational force is transmitted from cog to cog, the driven shaft rotates more slowly than the driving shaft, as is well-known in the art. This is to ensure that the rate of rotation is sufficiently reduced when it is transmitted to the main cog 9 to ensure that the operation of the dildo 4 (described below) realistically replicates the action of an erecting penis.

(12) As the main cog 7 rotates it transmits its rotational force, via a shaft connected to its hub, to the pulley wheel 12. A cord (not shown) is attached to a hub of the pulley wheel 12 and extends through the interior of the dildo 4. The cord is attached at its opposite end to a point on the interior of the tip of the dildo 4, i.e. the segment most distal from the first and second housing sections 3, 14.

(13) As the pulley wheel 12 rotates, the cord is progressively wrapped around the pulley wheel 12 such that its effective overall length from the pulley wheel 12 shortens. This has the effect that the tip of the dildo 4 is drawn toward the pulley wheel 12. The dildo 4 comprises a plurality of hinged section, connected along shared hinge lines at the point where they meet one another, such that each hinged section can rotate slightly with respect to the neighbouring hinged section. This arrangement enables the dildo 4 to smoothly change shape from a first, flaccid configuration, in which the dildo curves towards the plane of the housing sections 3, 14 to lie substantially flat against the housing, to a second, erect configuration, in which the dildo 4 extends substantially straight and perpendicular to the housing.

(14) The controller 11 has a control element located on it, adjacent to the pulley wheel 12. A profiled outer surface of the shaft of the pulley wheel 12 contacts the control element. The controller 11 is configured such that it terminates current flow from the battery 13 to the electric motor 5 when the control element loses contact with the profiled outer surface. This arrangement acts as an automatic cut-off to the movement of the dildo 4 between the first and second configurations. The extent of the profiled outer surface may be varied as appropriate to correspondingly set the extent of the range of motion of the dildo 4.

(15) In this configuration, the user may press the second switch on the switch cover 1. This causes the associated electronic switch on the PCB 2 to be operated, which in turn causes current to flow from the battery 13 via the controller 11 along a plurality of wires (not shown) to a vibration motor 15 housed in the tip of the dildo (see FIG. 2). The operation of the switch may be a simple on/off signal in response to the pressing of the second switch, or the switch may turn the vibration motor 15 on for a pre-determined amount of time (e.g. ten seconds) before automatically turning the vibration motor 15 off again. This operation may be controlled by control circuitry in the controller 11.

(16) When it is desired to return the dildo 4 to its first, flaccid configuration, a user presses the first switch on the switch cover 1 again, and the associated electronic switch on the PCB 2 is operated. This causes current to flow from the battery 13 to the electric motor 5, via the controller 11 along a plurality of wires (not shown). Once activated, the electric motor 5 rotates the worm gear 6, which is attached to an output shaft of the electric motor 5, in a second direction opposite to the first direction.

(17) The operation described above is carried out in the same manner, except that the rotational force transmitted between the cogs is in the opposite direction.

(18) As the pulley wheel 12 rotates in the opposite direction, the cord is paid out from the pulley wheel 12. A coil spring (see FIG. 2) extends from an anchor point on the first and second housing sections, through the dildo 4 to an anchor point at the tip of the dildo 4 where its opposite end is secure. The coil spring biases the dildo 4 into the first configuration, and the cord must overcome this biasing force in order to move the dildo 4 from the first position to the second configuration. Consequently, as the cord is paid out from the pulley wheel 12, the biasing force of the spring takes up the slack and the segments of the dildo 4 move under the force of the spring back into the first configuration.

(19) The controller 11 automatically cuts off the flow of electrical current from the battery 13 to the electric motor 5 as described above, but with the control element reaching the opposite end of the profiled outer surface of the shaft of the pulley wheel 12.

(20) FIG. 2 schematically shows a cross-sectional view of the dildo assembly of FIG. 1. In this view, the vibration motor 15, the spring 16 and the cord 17, referred to in the preceding paragraphs, can each be seen at the points indicated.

(21) FIG. 3 schematically shows a cross-sectional view of the first housing section 3 of the dildo assembly of FIG. 1. Here, the an electric motor 5, the worm gear 6, the main cog 7, the three intermediate cogs 8 and the worm wheel 9 can be seen in their assembled state.

(22) An electrical connector 18 is also shown in this view. The electrical connector 18 is electrically coupled to the battery 13, and so a user can charge the battery 13 by connecting a power source to the electrical connector 18.

(23) FIG. 4 schematically shows a cross-sectional view of the second housing section 14 of the dildo assembly of FIG. 1. The controller 11, the pulley wheel 12 and the battery 13 can be seen in their assembled state. The control element 19 of the controller 11 is also shown in more detail.

(24) Alternative Arrangements

(25) The invention is not limited to the specific embodiments disclosed above, and other possibilities will be apparent to those skilled in the art. For example, only the skeleton of the dildo assembly is shown in FIG. 1. In practice, this would be covered by a sleeve of material designed to replicate the texture of a penis, e.g. silicone. The number of segments can be varied to provide dildos of greater or lesser length to suit individual requirements, and the range of motion can be varied by adjusting the profiled outer surface of the pulley wheel, the controller and the strength of the coil spring.

(26) A suction cup may be formed on the housing, to allow the dildo assembly to be attached to a wall, floor, table or other surface. An example of this embodiment is shown in FIG. 5see suction cup 20. The suction cup may also be engaged with an o-ring of a strap or harness, so that the dildo assembly can be worn by a user for the purposes of pegging or similar activities. Alternatively or additionally, the housing may comprise mounting points for a strap or harness.

(27) The controller may have a wireless connectivity module to enable the electric motor 5 and/or vibration motor 15 to be operated by a remote control in addition to, or instead of, the switches on the switch cover. The wireless connectivity may take place via any suitable protocol, e.g. the Bluetooth protocol or wi-fi.

(28) While the embodiments of FIGS. 1-5 have a rechargeable battery, the invention could instead be powered by non-rechargeable batteries that can be removed and replaced by a user.
