DESCRIPTION

Three-movement tactile stimulation device

Technical field

This description relates generally to an apparatus for use in sexual devices and massage instruments, and more particularly to an apparatus for promoting tactile stimulation using radial vibration, orbital motion, and rotational or torsional oscillation.

Background of the invention

It is well known that many personal appliances or small mechanical devices in the form of sex devices and massage instruments use rotary drive energy or servo motors in generating fine movements, such as radial vibration. Conventional masturbation and massage devices typically provide radial vibratory energy, rotational energy, or oscillations in two axes. Generally, devices with this type of energy conversion exist as a healthy sexual outlet and can be valuable tools in sex therapy, including enhancing sexual awareness and reducing fears of intimacy. The vast majority of women, in particular, cannot climax without external stimulation. Devices that allow masturbation have the potential to decrease unwanted births and decrease the transmission of sexually transmitted diseases, as they can be implemented without a partner. Furthermore, the utility of self-massage devices is well known, as there are many commercially available. In fact, there are a multitude of handheld, vibrator, and double-action massagers.

In 2003, a comprehensive analysis of the sex device market was conducted, as best described in US Patent No. 6,902,525 to Jewell. Specifically, the need for sexual devices to provide greater personal pleasure to people with all types of sexual dispositions was identified. The most common of these devices currently available is the vibrating vibrator or dildo or vibrating massager. While these types of devices are commonly known and inexpensive to manufacture, they provide less than optimal stimuli, mostly random and primarily radial pulses.

Typically the common characteristic between these devices is a simple unbalanced weight driven by a motor. One of the most popular vibratory massage devices is the one made by Hitachi, and it is unique in that the weight is supported by bearings in a section of the stimulator that is distal to the motor and wrapped in a flexible material. This design gives the stimulator more freedom and protects the motor from radial loads. It was a generous leap in terms of massager / stimulator design, but it does not directly create higher amplitude percussive or mechanical gliding movements that can activate specialized sensory receptors found in human genitalia.

Histological analysis of human genitalia supports the relevance of various stimuli. Sensory receptors in human genitalia are unique in distribution and type, even among glabrous (hairless) skins. The human penis contains a large number of free nerve endings, as well as more complex corpuscular receptors. The density and type of receptor affect the types of stimuli that a particular skin area can perceive and the sensitivities to them. For example, the distal aspect of the penis has little fine touch sensation compared to its ability to feel pressure and pain. The foreskin, on the other hand, has a greater number of specialized corpuscular or fine touch receptors. These more complex receptors have a higher density around the crown and the transition zones between the foreskin and the glans. In the female clitoris, similar receptor types / distributions can be found, as the clitoris is embryologically related to the penis.

A variety of adaptation times can be found between the types of sensory receptors in the genital organs. Some have fast adaptation times that produce a decrease in production with constant stimulation, and some have slow adaptation times. An effective stimulator will fully activate a variety of receptors, including mechanoreceptors that increase their production depending on the degree of pressure or deformation of the skin, as well as slowly adapting receptors that respond to stretching. Enhanced stimulation of the genitalia cannot be achieved by a simple mid-frequency vibration that creates minimal stretching and displacement of sensory receptors. Many genital mechanoreceptors will respond to this through adaptation with a decrease in sensory receptor production over time.

A large number of personal stimulation devices are known from the state of the art; see, for example, DE 10 2010 018391 (on which the preamble of claim 1 is based), JP 2006-110289, WO 2013/138658, WO 2009/012172, US 2013/0197302 and the aforementioned US 6902525. However, neither provide stimulation through vibratory, orbital, and torsional (or rotational) oscillations.

ES 2 837 151 T3

Therefore, a need exists for a device designed to provide a safe method of effective tactile stimulation that provides additional mechanical stimulation through vibratory, orbital, and torsional (or rotational) oscillations. Additionally, the device should have the added benefit of increased stimulation, as well as superior massage characteristics by generating additional gliding and pressure stimuli. The device must be capable of being used alone or as an attachment to other commercially available devices.

Detailed description

In the following detailed description, reference is made to the accompanying drawings that form a portion thereof, and in which are shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to allow those skilled in the art to carry out

In practice the embodiments and like numbers represent similar details in the various figures. Furthermore, it should be understood that other embodiments can be used and that processes or other changes can be made without departing from the scope of the disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of the invention is defined solely by the appended claims and their equivalents. In accordance with the description, a three-movement tactile stimulation device or apparatus is described below. The device is designed to take rotational energy and convert that energy into a vibratory, orbital and torsional stimulator for the purpose of massage and sexual stimulation.

Returning to Figures 1-4, it shows a three-movement tactile stimulation device 10 in a standard configuration that provides effective sexual stimulation or massage to the person using the device. Device 10 includes a body or housing made of a lightweight and durable material, such as polyvinyl chloride (PVC) or high-density polyethylene. The device can also be wireless for ease of use. Additionally, device 10 can be variable speed, programmable, affordable, waterproof, multimodal, and tunable. Advantageously, device 10 is gender neutral. The device uses rotational energy to create orbital motion, torsional oscillation, and radial vibration.

Device 10 typically includes a power unit or battery compartment 20 and a stimulator segment or active segment 30 as illustrated in Figure 1. Power unit 20 is comprised of a hollow cylinder to maintain battery power, with a removable access cover 40 containing a variable speed control. In addition, the power unit 20 is programmable to provide different modes of operation, including, but not limited to, variable speed, on / off cycles, and enhanced torsional and orbit control. Access cover 40 is designed to ensure watertightness and a means for external manipulation of a voltage or variable control 50. The means for external manipulation of the voltage or variable control 50 may be a physical rotary control switch, a magnetic switch, a knurled disk, a shielded push button control or the like for varying the speed and direction of the device. Specifically, changing the polarity associated with the controller will change the direction of the device. In one embodiment, the variable control 50 is linked to a variable electrical resistance that varies the output voltage of at least one supply or power source 60 located within the power unit 20. The control or control circuit of the power unit Power 55 includes variable electrical resistance and / or a programmable circuit.

The external control means 50 uses a flexible O-ring 70 to prevent water infiltration into the access cover 40. The access cover 40 is attached to the cylinder of the power unit by threading and has a gasket 80 to prevent penetration. of water. It should be appreciated that multiple approaches could be taken to control the voltage of the power unit 20. For example, a waterproof push button, film control, or magnetic or wireless control can be used to initiate power to power unit 20. Power source 60 may be in the form of a battery unit, which can be easily removable for recharging and / or replacement. Other embodiments could include batteries or capacitors using other chemical components, plug-in rechargeable batteries, external power, or a fully sealed power unit using inductive or kinetic / inductive charging means. Power unit 20 may be electrically fused and contains a means for controlling heat. For example, a thermally active fuse and a housing that isolates the user from the motor can be the means of controlling heat.

At the distal end of power unit 20 is a DC high torque ball bearing motor 90 which is relatively small. The motor 90 is coupled to the cylinder 20 of the power unit. The motor 90 has a durable output shaft 10 that can project into the stimulator segment 30. It would be possible to minimize radial loads on the motor and provide a means of safety by making the output shaft 100 from a flexible material, such as steel for springs. The output shaft 100 may be supported by a bearing.

Returning to Figure 4, stimulator segment 30 contains a weighted or dense eccentric coupler 110 with two openings. The weighted coupler 110 generates and modulates both the amplitude of the radial vibration and the radius of the orbit of the stimulator segment. Orbit is accomplished through a second axis or axis, stimulator axis 120, which is discussed in more detail below. Weighted coupler 110 is securely connected to output shaft 100 by press fit or other suitable means. Stimulator segment 30 can be protected from inadvertent disassembly by at least one flexible safety wire connecting the power unit to the stimulator.

Radial to the output shaft, the second opening in the weighted coupler is used to hold the shaft of the proximal stimulator 120. The shaft of the stimulator 120 is securely connected to the weighted coupler 110. Specifically, the shaft of the stimulator 120 can be press fit. to the weighted coupler in an off-center manner, projecting distally. Importantly, safety measures such as multiple fasteners can be employed to prevent loosening and slipping. The opposite or distal end of the stimulator shaft 120 is securely pressed into an inner opening of a sealed ball bearing 130, which is surrounded by a flexible cover 140, preferably made of rubber. The flexible cover 140 is pressed firmly onto the rigid cap of the stimulator 150. Alternatively, the stimulator cap 150 and the flexible bearing cover 140 may be a single element where the cover actually forms the cap. The outer race of the sealed ball bearing maintains a nearly constant bearing so that the stimulator does not rotate with the second axis.

Stimulator cap 150 has a wider bell portion that is similar in diameter to power unit cylinder 20 and there is a gap between major components. The space between the rigid portion of the power unit and the bell of the stimulator cap allows it to orbit and twist the active segment of the device. Alternatively, the stimulator segment could take the shape of a capsule or several different shapes, such as a cone with a shallow domed bulge. Surrounding the entire assembly is a durable stretch flexible cover 160 that completes the waterproofing. Flexible cover 160 can be made of silicone or other thermoplastic material. In addition, this cover provides the bridge between the stimulator segment 30 and the power unit 20. The flexible bridge allows and facilitates orbital and torsional oscillatory movements of the stimulator segment of the device.

In addition, the flexible cover is capable of eliminating independent three hundred and sixty-degree (360 °) rotation of the stimulator by bridging the power source housing and the stimulator, allowing for orbiting and twisting or stretching torsional oscillation. elasticity. It should be appreciated that careful adjustment of stimulator segment weight, weighted coupler, stimulator cap imbalance, stimulator cap clock position, orbit radius and velocity, and flexible cover can all be use to control the character of the orbit, vibration and torsional oscillation. The flexible cover 160 is waterproof and removable. Importantly, the flexible cover is easily cleaned and sterilized by placing it in a steam or chemical sterilization device. In one embodiment, the flexible cover can change color with changes in temperature. The flexible cover 160 can further be used to seal a joint between the power unit 20 and the access cover 40.

As should be appreciated, the main elements in this embodiment become the unbalanced cap of the stimulator that sits on a bearing and the small space covered by the flexible cover. The orbit / rotation movement of the stimulator segment, along with the small resistance in the bearing allows the stimulator segment to roll, stretch the flexible cover and release to initiate torsional oscillations with varying amplitudes. Increasing the stiffness (modulus) of the flexible cover or increasing the stress within the material decreases the amplitude of the torsional oscillation . By allowing more freedom between the stimulator segment and the power unit, loosening the bridge material or decreasing its modulus, the opposite effect is created. External resistance at a fixed point along the path of the stimulator segment creates a variable response, the most common of which is an effective increase in torsional amplitudes. Other design benefits are intended to increase safety and flexibility for the user. The flexible cover on the stimulator cap is capable of reducing the percussive effects of the stimulator segment if it is held against a stationary object. The ball bearing in the stimulator section facilitates torque reduction if the device is sufficiently supported. The shape of the stimulator segment allows the user to increase or decrease slip, orbital and percussive energy by utilizing different surfaces along the bell-shaped stimulator lid.

In another embodiment illustrated in Figure 5, the sealed ball bearing is replaced by a low torque clutch and release assembly without a motor or a miniature electric clutch assembly 170 that can further vary the amplitude of the torsional oscillation. With the electric clutch, a programmable circuit can control the amplitudes and periodicity of the torsional slip forces. This could be done wireless or programmable and controlled via a Bluetooth device or similar mobile electronic device. It should be appreciated that the programmable circuitry and the wireless and programmable capabilities apply to the entire device.

Returning to Figure 6, a separate DC motor 180 could be used to replace the bearing. In this embodiment, the output shaft of the second motor is directed proximally to the weighted coupler, which would offer greater control of torsional movements through braking and acceleration and could be made wireless and / or programmable.

With respect to Figures 7a-7e, a complex weighted coupler 190 can be used to reduce the distance between the stimulator shaft and the motor output shaft when the DC motor rotates in one direction and increases when the DC motor rotates. in the opposite direction. Advantageously, this would give the operator the ability to change the amplitude of the orbital percussion pulses and would affect the amplitude of the torsional movements. Specifically, Figure 7b illustrates the coupler 190 that includes the stimulator shaft and a cylinder, which secures the coupler to the motor output shaft. Figure 7c shows an inside view of the coupler. Returning to Figures 7d and 7e, they illustrate a side view of the input shaft of the coupler that includes a plurality of shims or washers 200 along with a retaining means 210, such as a C-clip.

In yet another embodiment illustrated in Figure 8, the stimulator segment 30 may include a device to alter the profile of the stimulator segment and alter the radius of the orbit. The device may be an electrosolenoid or a group thereof, an electroactive shape memory polymer, or a thermally active shape memory polymer. The profile of the stimulator not only changes the orbit, but creates more imbalance of the stimulator segment 30, increasing the amplitude of the torsional oscillation. For example, the stimulator cap could be replaced by a corn kernel shaped electrical transformer 220 or an electroactive shape memory polymer to change the shape and characteristics of the orbit and torsional oscillation. The shape or balance of the stimulation segment or section could be controlled by these means.
