The present invention is in the field of devices for sexual stimulation, and more particularly in the field of devices for male masturbation.
There are various male sexual stimulation devices known in the prior art. The mechanisms by which stimulation is provided in these devices generally fall into one of five basic types: manual sheath mechanisms, vibratory mechanisms, suction mechanisms, constriction mechanisms, and direct electrical stimulation mechanisms. All of the existing mechanisms have one or more significant disadvantages, including non-ideal stimulation, possible release of bodily fluids, difficulty of use, and inability to customize the speed, pattern, and location of stimulation.
Further, existing devices do not provide a gripper mechanism that allows for adjustment in gripper diameter based on individual variations in the girth of penises or based on individual preferences regarding tightness while still retaining the performance characteristics of a rigid gripper.
What is needed is an adjustable gripper mechanism for male masturbation devices that provides a better user experience by allowing for adjustment in gripper diameter based on individual variations in the girth of penises or based on individual preferences regarding tightness.
Accordingly, the inventor has conceived, and reduced to practice, 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.
According to a preferred embodiment, an adjustable gripper mechanism for male sexual stimulation devices is disclosed, 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.
According to another preferred embodiment, an adjustable gripper mechanism for male sexual stimulation devices is disclosed, 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.
According to an aspect of an embodiment, the screw adjustment mechanism is motorized via motor, servo, or actuator.
According to an aspect of an embodiment, the mechanism further comprises 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.
According to an aspect of an embodiment, 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.
According to an aspect of an embodiment, 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.
The accompanying drawings illustrate several aspects and, together with the description, serve to explain the principles of the invention according to the aspects. It will be appreciated by one skilled in the art that the particular arrangements illustrated in the drawings are merely exemplary, and are not to be considered as limiting of the scope of the invention or the claims herein in any way.
The inventor has conceived, and reduced to practice, 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.
The mechanisms by which stimulation is provided in male sexual stimulation devices generally fall into one of five basic types: sheath type strokers, vibratory mechanisms, suction mechanisms, constriction mechanisms, and direct electrical stimulation mechanisms. Each of these devices has at least one significant disadvantage that is overcome by the present invention.
The sheath type stroker is tube-shaped device made of thermoplastic elastomer, thermoplastic rubber, silicone or other soft, flexible material, with or without an enclosing shell, into which the penis is inserted. The entire stroker is moved up and down the shaft of the penis, causing stimulation by the friction and pressure of the sheath against the penis. Sheath type strokers are used manually, requiring significant user effort, and possibly repetitive strain injury. Some use a condom-like sleeve which can slip while in use, and either stretch, compress, or even slip off entirely and become lodged in the sheath. Sheath type strokers expose the majority of the penis as the device is moved up and down the shaft of the penis, increasing the likelihood of release of bodily fluids outside of the device. Release of fluids outside of the device creates health and safety dangers to the user and others, can contaminate or damage other surfaces and materials onto which the fluids leak, and can make cleaning of the device itself difficult.
Vibratory mechanisms cause stimulation through oscillatory vibrations, usually created by an electric motor with an offset weight on the motor shaft. In many examples of vibratory mechanisms, for example the Hitachi Wand vibrator, the mechanism is simply pressed against the penis, causing stimulation by transmitting the vibration to the penis. In some forms of the vibratory mechanism, the penis may be inserted into the vibratory mechanism. Vibratory type devices provide a non-ideal type of stimulation, substituting vibration for the reciprocal linear motion of sexual intercourse. Further, most vibratory devices do not enclose the penis, and thus do not possess any method for containing bodily fluids. Vibratory mechanisms, in particular, also tend to produce substantial noise. While they sometimes allow the user to select different vibration patterns, such patterns do not provide much variance in stimulation, as they simply turn the device on and off at specified intervals.
Suction type devices are typically hard plastic tubes into which the penis is inserted at one end, and a suction pump is affixed to the other end. Suction type devices provide no direct stimulation through pressure or friction against the penis, and therefore provide substantially less than ideal stimulation. Suction devices may be combined with a sheath type mechanism.
A constriction type device is one in which the penis is inserted, and a set of rings either restrict blood flow back to the body, enhancing erection, or otherwise put inward radial pressure on the penis. Constriction type devices provide a non-ideal type of stimulation, substituting a squeezing motion for the reciprocal linear motion of sexual intercourse. Further, many constriction type devices do not enclose the penis, and thus do not possess any method for containing bodily fluids.
A direct electrical stimulation device is one in which the penis is stimulated through moderate voltage, very low current electrical shock. The electric shock stimulates nerve endings in the penis and may cause muscle contractions in surrounding tissue. The stimulation may be pulsed to provide different stimulation patterns. Direct electrical stimulation type devices provide a non-ideal type of stimulation, substituting electric shock pulses for the reciprocal linear motion of sexual intercourse. Further, most direction electrical stimulation type devices do not enclose the penis, and thus do not possess any method for containing bodily fluids.
The present invention overcomes the deficiencies in other devices by providing ideal stimulation, similar in pressure and motion to that obtained during sexual intercourse or oral sex, in a device where the user can control the speed, pattern, and location of the motion, and where the penis remains fully enclosed in a hygienic sheath during stimulation. This device is substantially quieter than many of the alternatives, and provides substantially different stimulation in each of its user-selectable modes or patterns by allowing the user to choose where the stimulation should occur, how often it should occur at selected locations, and how fast it should occur at those locations.
The device may be controlled by an integrated circuit (IC) built into the device which controls the operation of the motor and monitors any sensors in the device. The IC may be pre-programmed or may, through a universal serial bus (USB) or other interface, be user programmable using a computer application. In either case, the IC may control the operation of the device by adjusting motor speed and direction to implement the patterns of stimulation programmed into the IC. Sensors in the device may be used to set limits of motion of the nut and screw mechanism, to ensure that the mechanism is at one end of its range of motion prior to operation, or to detect and protect against other device parameters such as motor over-heating. Sensors may be of any type suitable for the purpose, including but not limited to electrical contacts, magnetic sensors, magnetic reed switches, mechanical switches, rotational sensors, optical sensors, and temperature sensors.
In an embodiment, the rotary motion from a small electric motor is translated to a linear motion through the use of a screw shaft and nut. The linear motion is translated into penile stimulation by a gripper that provides pressure against the penis through the sleeve as it glides up and down the shaft of the penis. Bodily fluids are contained within a flexible sheath inserted into the gripper, and into which the penis is inserted during use. This differs from sheath type devices in that the penis remains fully inserted in the device while in use, and the device itself is not drawn up and down the penis as with sheath type devices.
In some embodiments, the linear motion may be provided by other linear motion mechanisms. A non-exhaustive list of linear motion mechanisms that could be used in certain embodiments includes: ball screw mechanism, belt-drive linear actuator, linear motor, slider-crank mechanism, and hydraulic or pneumatic linear actuator. The use of these other linear motion mechanisms in certain embodiments will be described herein. Generally speaking, any mechanism capable of generating a linear motion could be used.
In some embodiments, the gripper mechanism may take a variety of alternate forms. A non-exhaustive list of alternative gripper mechanisms that could be used in certain embodiments includes: tubular gripper, annular (ring) gripper, partial-tube or partial-ring gripper, loop or band gripper (including loops and bands made of wire, plastic, metal, or other materials, and including multiple loops or bands), magnetic gripper, gripper with built-in heating elements, inflatable gripper, and vibrating gripper, a gripper with leaf springs or flexible plastic tines. The use of these other gripper mechanisms in certain embodiments will be described herein. It is important to note that the gripper is not limited to mechanisms or structures that “grip” by providing radial inward pressure (for example, leaf springs or flexible plastic tines), although such structures can be used. Generally speaking, any mechanism or structure to which a flexible sleeve may be affixed and which is capable of providing friction against a penis during linear motion may be used as a gripper.
In some embodiments, the linear motion may be augmented with a rotational motion of the gripper. For example, the guide rods supporting the gripper along which the linear motion occurs could be tilted or configured in a spiral, such that each travel along the guide rods causes the gripper to partially rotate about a longitudinal axis parallel to the linear motion. Alternatively, a motor or actuator could be attached to the gripper mechanism to rotate the gripper about a longitudinal axis parallel to the linear motion as it travels in a linear motion.
In some embodiments, the linear motion may be augmented by changing the direction of the linear motion. For example, a pivot could be installed at the bottom of the guide rods, and a gear attached to the linear motion driver such that the linear motion causes the guide rods to tilt, changing the direction of the linear motion during each travel along the guide rods. Alternatively, a separate motor, driver, or actuator could be installed, which changes the pivot angle of the guide rods independently of the linear motion.
Optionally, the device may include a number of other functions to enhance the user experience. For example, a grippable surface may be molded to the outside of the housing to provide better grip in the hand. The device may contain the ability to warm the sheath to an optimal temperature prior to and during use. The device may also contain additional methods of stimulation in addition to the primary linear motion, such as suction, vibration, or direct electrical stimulation. The device may be made more portable by designing it to operate from batteries contained within the device housing. It will be apparent to one skilled in the art, that the linear motion could be generated by some other means than a rotary electric motor.
One or more different aspects may be described in the present application. Further, for one or more of the aspects described herein, numerous alternative arrangements may be described; it should be appreciated that these are presented for illustrative purposes only and are not limiting of the aspects contained herein or the claims presented herein in any way. One or more of the arrangements may be widely applicable to numerous aspects, as may be readily apparent from the disclosure. In general, arrangements are described in sufficient detail to enable those skilled in the art to practice one or more of the aspects, and it should be appreciated that other arrangements may be utilized and that structural, logical, software, electrical and other changes may be made without departing from the scope of the particular aspects. Particular features of one or more of the aspects described herein may be described with reference to one or more particular aspects or figures that form a part of the present disclosure, and in which are shown, by way of illustration, specific arrangements of one or more of the aspects. It should be appreciated, however, that such features are not limited to usage in the one or more particular aspects or figures with reference to which they are described.

Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more communication means or intermediaries, logical or physical.
A description of an aspect with several components in communication with each other does not imply that all such components are required. To the contrary, a variety of optional components may be described to illustrate a wide variety of possible aspects and in order to more fully illustrate one or more aspects. Similarly, although process steps, method steps, algorithms or the like may be described in a sequential order, such processes, methods and algorithms may generally be configured to work in alternate orders, unless specifically stated to the contrary. In other words, any sequence or order of steps that may be described in this patent application does not, in and of itself, indicate a requirement that the steps be performed in that order. The steps of described processes may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to one or more of the aspects, and does not imply that the illustrated process is preferred. Also, steps are generally described once per aspect, but this does not mean they must occur once, or that they may only occur once each time a process, method, or algorithm is carried out or executed. Some steps may be omitted in some aspects or some occurrences, or some steps may be executed more than once in a given aspect or occurrence.
When a single device or article is described herein, it will be readily apparent that more than one device or article may be used in place of a single device or article. Similarly, where more than one device or article is described herein, it will be readily apparent that a single device or article may be used in place of the more than one device or article.
The functionality or the features of a device may be alternatively embodied by one or more other devices that are not explicitly described as having such functionality or features. Thus, other aspects need not include the device itself.
Techniques and mechanisms described or referenced herein will sometimes be described in singular form for clarity. However, it should be appreciated that particular aspects may include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. Process descriptions or blocks in figures should be understood as representing modules, segments, or portions of code which include one or more executable instructions for implementing specific logical functions or steps in the process. Alternate implementations are included within the scope of various aspects in which, for example, functions may be executed out of order from that shown or discussed, including substantially concurrently or in reverse order, depending on the functionality involved, as would be understood by those having ordinary skill in the art.
The spiraling sleeve of this example comprises a tubular or approximately tubular sleeve body 2411, open at one end and closed at the other, comprised of an elastomeric material or materials having a plurality of protrusions or depressions (e.g., ribs, ridges, grooves, etc.) 2412 formed into the interior of the sleeve body 2411 arranged at some angle or angles 2416 away from the longitudinal axis 2417 of the tubular sleeve body 2411. The plurality of protrusions or depressions 2412 may be formed at intervals 2418, whether regular, or irregular, or some combination of both. The protrusions or depressions may be linear in shape with an angle away from the longitudinal axis, as shown, or may be of other shapes (e.g., circles, squares, bumps, spikes, etc.) of any orientation but arranged in an spiraled pattern relative to the longitudinal axis). The spiraling sleeve of this example further comprises an opening flange 2415, which serves to retain the open end of the spiraling sleeve at the opening of a mechanical stroking mechanism, and flanges 2413, 2414 at or near the closed end of the spiraling sleeve which serve to provide a purchase for a gripper to elongate and/or shorten the spiraling sleeve. In some embodiments, the protrusions or depressions may be formed from a material other than the elastomeric material (e.g., a flexible plastic). In some embodiments, the angle or angles 2416 may be formed of a material other than the elastomeric material (e.g., a flexible plastic) and also enclosed within the elastomeric material, whether or not protruding from the interior surface of the sleeve. In such case, the differential in tension between the elastomeric material and the material forming the angle or angles 2416 causes the twisting motion. In some embodiments, a combination of protrusions or depressions arranged in a spiral pattern plus a spiral of a different material enclosed within the elastomeric material will cause the twisting motion.
At 2410, the spiraling sleeve is shown in a neutral state as molded, neither elongated nor shortened. At 2420, the spiraling sleeve is shown in a shortened state, a gripper (not shown) between the flanges 2413, 2414 having applied a shortening or compressing force in the direction of arrow 2421. As the spiraling sleeve is compressed, the elastomeric material of the body 2411 of the spiraling sleeve will tend to become thicker and may bulge outward 2423 under the force of the compression. At the same time, the plurality of protrusions or depressions 2412 will compress together 2424 causing friction against an erect penis inside the sleeve, causing the body 2411 of the spiraling sleeve to twist in the direction of the downward slope of the angle or angles of the plurality of protrusions or depressions 2422. In this case, the twist would be in the clockwise direction when viewed from the top of the closed end looking down along the longitudinal axis 2417. At 2430, the spiraling sleeve is shown in an elongated state, a gripper (not shown) between the flanges 2413, 2414 having applied an elongating or stretching force in the direction of arrow 2431. As the spiraling sleeve is elongated, the elastomeric material of the body 2411 of the spiraling sleeve will tend to become thinner and may pull inward 2433 under the force of the elongation. At the same time, the plurality of protrusions or depressions 2412 will stretch away from one another 2434 causing friction against an erect penis inside the sleeve, causing the body 2411 of the spiraling sleeve to twist in the direction of the upward slope of the angle or angles of the plurality of protrusions or depressions 2432. In this case, the twist would be in the counter-clockwise direction when viewed from the top of the closed end looking down along the longitudinal axis 2417. In this exemplary embodiment, as the end with the flanges 2413, 2414 is closed, elongation of the spiraling sleeve will tend to cause suction within the body of the spiraling sleeve, further increasing the friction of the plurality of protrusions or depressions 2412 against the penis, which both adds a pleasurable sensation and increases the tendency of the sleeve to twist.
The spiraling sleeve of this example comprises a tubular or approximately tubular sleeve body 2511, open at one end and closed at the other, comprised of an elastomeric material or materials having one or more protrusions or depressions (e.g., ribs, ridges, grooves, etc.) 2512 formed in one or more continuous spirals into the interior of the sleeve body 2511 arranged at some angle or angles 2516 away from the longitudinal axis 2517 of the tubular sleeve body 2511. The plurality of protrusions or depressions 2512 may be formed at intervals 2518, whether regular, or irregular, or some combination of both. The protrusions or depressions may be linear in shape with an angle away from the longitudinal axis, as shown, or may be of other shapes (e.g., circles, squares, bumps, spikes, etc.) of any orientation but arranged in an spiraled pattern relative to the longitudinal axis). The spiraling sleeve of this example further comprises an opening flange 2515, which serves to retain the open end of the spiraling sleeve at the opening of a mechanical stroking mechanism, and flanges 2513, 2514 at or near the closed end of the spiraling sleeve which serve to provide a purchase for a gripper to elongate and/or shorten the spiraling sleeve. In some embodiments, the protrusions or depressions may be formed from a material other than the elastomeric material (e.g., a flexible plastic). In some embodiment, the one or more continuous spirals may be formed of a material other than the elastomeric material (e.g., a flexible plastic) and also enclosed within the elastomeric material, whether or not protruding from the interior surface of the sleeve. In such case, the differential in tension between the elastomeric material and the material of the one or more continuous spirals causes the twisting motion. In some embodiments, a combination of protrusions or depressions arranged in a spiral pattern plus a spiral of a different material enclosed within the elastomeric material will cause the twisting motion.
At 2510, the spiraling sleeve is shown in a neutral state as molded, neither elongated nor shortened. At 2520, the spiraling sleeve is shown in a shortened state, a gripper (not shown) between the flanges 2513, 2514 having applied a shortening or compressing force in the direction of arrow 2521. As the spiraling sleeve is compressed, the elastomeric material of the body 2511 of the spiraling sleeve will tend to become thicker and may bulge outward 2523 under the force of the compression. At the same time, the continuous spiral protrusions or depressions 2512 will compress together 2524 causing friction against an erect penis inside the sleeve, causing the body 2511 of the spiraling sleeve to twist in the direction of the downward slope of the angle or angles of the continuous spiral protrusions or depressions 2522. In this case, the twist would be in the clockwise direction when viewed from the top of the closed end looking down along the longitudinal axis 2517. At 2530, the spiraling sleeve is shown in an elongated state, a gripper (not shown) between the flanges 2513, 2514 having applied an elongating or stretching force in the direction of arrow 2531. As the spiraling sleeve is elongated, the elastomeric material of the body 2511 of the spiraling sleeve will tend to become thinner and may pull inward 2533 under the force of the elongation. At the same time, the continuous spiral protrusions or depressions 2512 will stretch away from one another 2534 causing friction against an erect penis inside the sleeve, causing the body 2511 of the spiraling sleeve to twist in the direction of the upward slope of the angle or angles of the continuous spiral protrusions or depressions 2532. In this case, the twist would be in the counter-clockwise direction when viewed from the top of the closed end looking down along the longitudinal axis 2517. In this exemplary embodiment, as the end with the flanges 2513, 2514 is closed, elongation of the spiraling sleeve will tend to cause suction within the body of the spiraling sleeve, further increasing the friction of the plurality of protrusions or depressions 2412 against the penis, which both adds a pleasurable sensation and increases the tendency of the sleeve to twist.
The adjustable gripper portion 2610 of this embodiment is an approximately tubular shape with openings at each end of the longitudinal axis of the tubular shape, and comprises a left tubular portion 2611, a right tubular portion 2612, a hinge 2613 connecting the two tubular portions 2611, 2612 on one side of the tubular shape, a screw connecting the two tubular portions 2611, 2612 on the other side of the tubular shape, and a screw adjustment mechanism comprising a screwdriver tip socket 2616 (here, for a Phillips head screwdriver) for adjusting the gap between the two tubular portions 2611, 2612 at the screw-connected side of the tubular shape. As the screw driver tip socket is turned (e.g., using a screwdriver), a worm gear mechanism (not shown) inside the right tubular portion 2612 causes the screw 2615 to turn inside a threaded portion (not shown) of the right tubular portion 2612, forcing the left tubular portion 2611 toward or away from the right tubular portion 2612 apart as shown in 2617, depending on the direction of operation of the. While this embodiment shows the two tubular portions as halves (i.e., approximately half of the tubular shape), other configurations are possible wherein the two portions do not represent an equal portion of the tubular shape. Further, other configurations of the screw mechanism and screw are possible, such as a direct screw arrangement where in the head of the screw has the socket and no worm gear is required.
The carriage or traveler portion 2620 is attached to the adjustable gripper portion 2610 via a connector 2614. In this embodiment, the carriage or traveler 2620 has a screw nut 2622 with screw threads that convert rotational movement of a screw into a linear motion, and has two one guide rod sleeves 2621 configured to accept guide rods for stabilizing the linear movement of the carriage or traveler and preventing rotation of the carriage or traveler 2620. In some embodiments, the carriage or traveler portion 2620 may driven in its linear motion of travel by other mechanisms such as belts, rods, cams, or other such devices. In some embodiments, the carriage or traveler portion 2620 may be guided by other mechanisms such guide rails, guide slots or grooves, or guide enclosures such as a box or tube. The connector may be made of any suitable material and may be molded as a portion of the adjustable gripper 2610, or the carriage or traveler 2620, or as a separate component attachable to both.
The adjustable gripper portion 2610 of this embodiment is an approximately tubular shape with openings at each end of the longitudinal axis of the tubular shape, and comprises a left tubular portion 2611, a right tubular portion 2612, a hinge 2613 connecting the two tubular portions 2611, 2612 on one side of the tubular shape, a screw connecting the two tubular portions 2611, 2612 on the other side of the tubular shape, and a motorized screw adjustment mechanism 2701 comprising a motor, servo, or other actuator at the screw-connected side of the tubular shape. The motorized screw adjustment mechanism 2701 may have one or more wires 2702 for power and/or control which can be connected to a suitable power source such as a battery and/or to a controller for automated operation. As the motorized screw adjustment mechanism 2701 is operated, a worm gear mechanism (not shown) inside the right tubular portion 2612 causes the screw 2615 to turn inside a threaded portion (not shown) of the left tubular portion 2611, forcing the left tubular portion 2611 toward or away from the right tubular portion 2612 apart as shown in 2617, depending on the direction of operation of the motorized screw adjustment mechanism 2701. While this embodiment shows the two tubular portions as halves (i.e., approximately half of the tubular shape), other configurations are possible wherein the two portions do not represent an equal portion of the tubular shape. Further, other configurations of the motorized screw adjustment mechanism 2701 and screw are possible, such as a direct screw arrangement where motorized screw adjustment mechanism 2701 is attached in line to the head of the screw such that no worm gear is required. In some embodiments, the motorized screw adjustment mechanism 2701 may be integrated into one of the two tubular portions rather than extending externally as shown.
The carriage or traveler portion 2620 is attached to the adjustable gripper portion 2610 via a connector 2614. In this embodiment, the carriage or traveler 2620 has a screw nut 2622 with screw threads that convert rotational movement of a screw into a linear motion, and has two one guide rod sleeves 2621 configured to accept guide rods for stabilizing the linear movement of the carriage or traveler and preventing rotation of the carriage or traveler 2620. In some embodiments, the carriage or traveler portion 2620 may be driven in its linear motion of travel by other mechanisms such as belts, rods, cams, or other such devices. In some embodiments, the carriage or traveler portion 2620 may be guided by other mechanisms such guide rails, guide slots or grooves, or guide enclosures such as a box or tube. The connector may be made of any suitable material and may be molded as a portion of the adjustable gripper 2610, or the carriage or traveler 2620, or as a separate component attachable to both.
