Abstract:
The therapeutic apparatus of the present invention includes a portable case having a hollow interior for housing a motion-generating case or housing wherein the front end of the assembly is provided with an elongated slot for extending an elongated rod therethrough. The rod is provided with a resilient foam collar over which is mounted a penetration member adapted to penetrate a selected body orifice for providing sexual stimulation, gratification and pleasure. The motion-generating assembly within the hollow interior of the portable enclosure includes both a horizontal motion-generating assembly and a suspension assembly for producing a generally variable vertical up and down component to the motion provided by the horizontal drive assembly. An electric motor is used to drive an eccentric disk. A yoke positioned on the disk is adapted to move the elongated rod reciprocally back and forth in a generally horizontal direction. A suspension yoke positions the eccentric disk assembly in space and is suspended from the top end of a resilient support post which provides a vertical up and down component to the horizontal motion previously described. The combination of the two motions provide for continually varying strokes having different angles of penetration and angles of withdrawl for greatly increased sexual satisfaction.

Description:
BACKGROUND OF THE INVENTION 
     1. Field Of The Invention 
     This invention relates generally to a therapeutic apparatus, and more particularly to a motorized therapeutic apparatus for relieving tension and sexual frustration in women and/or men. 
     2. Description Of The Prior Art 
     There have always been men and women who become sexually frigid, impotent, or unable to practice normal sex for one or more reasons. For example, a woman&#39;s husband or spouse may be overly obese so as to render sex nearly impossible. Furthermore, males suffering from adult-onset diabetis may often become impotent. Yet further, users of certain medications such as anti-depressants and the like, often become impotent over long periods of time as a side effect of the medications. Still further, since men die a considerable number of years before their wives, according to today&#39;s statistics, the wife is quite often left without her normal or usual sex partner and has nowhere to turn for sexual satisfaction. 
     Conventional therapeutic devices available in the market place today include various types of vibrators and sex aids. Many of these sex aids require the use of another partner, either male or female. Furthermore, many do not provide the true &#34;feel&#34; of a male penis, and hence they do not result in true sexual gratification, enjoyment or satisfaction. Many are simply artificial, such as plastic vibrators, and cannot satisfy the true needs of a partnerless woman or male who wants not only the ultimate climax, orgasm or release but also the feeling that she or he is actually having sex with a partner. 
     Therefore, a long-felt, but unfulfilled, need has existed and continues to exist in the art for a therapeutic apparatus for more closely simulating sexual intercourse, anal intercourse, and the like, and which has the look and feel of a real male penis, and which can be used at any tempo, speed, or degree of gentleness or roughness, as desired by the user. 
     Still further, the need exists for an automatic or motorized therapeutic apparatus which can vary the stroke length, and continually and automatically vary the angle of penetration and withdrawl for even more closely resembling the conventional sex act. 
     The present invention solves substantially all of the problems of the prior art while avoiding any of its shortcomings. 
     BRIEF SUMMARY OF THE INVENTION 
     It is an object of the present invention to provide a therapeutic apparatus for relieving sexual tension and frustration in both men and women with or without sex partners. 
     It is another object of the present invention to provide a therapeutic apparatus which may utilize a continuously erect, yet resiliently pliable, artificial male penis for simulated sexual or anal intercourse wherein the penis has both the look and the &#34;feel&#34; of a male&#39;s erect penis. 
     It is a further object of the present invention to provide a motor-driven therapeutic apparatus for simulating sexual or anal intercourse which provides the required degree of gentleness or roughness, as desired by the user. 
     It is still another object of the present invention to provide a motor-driven apparatus for simulating sexual intercourse which is entirely under the control of the user. 
     It is still a further object of the present invention to provide a therapeutic apparatus which provides a continually varying angle of penetration and angle of withdrawl for even greater sexual gratification, stimulation, and satisfaction. 
     It is yet a further object of the present invention to provide a motor-driven therapeutic apparatus wherein the length of the stroke or depth of penetration may be selectively varied. 
     It is still another object of the present invention to provide a motor-driven therapeutic apparatus wherein the angle of penetration and angle of withdrawl can be continuously varied. 
     It is yet another object of this invention to provide a motor-driven therapeutic apparatus wherein both the length of the stroke and both the angle of penetration and the angle of withdrawl can be manually adjusted or selected by the user. 
     It is yet another object of the present invention to provide a motor-driven therapeutic apparatus wherein the penetration member may be selectively chosen from a plurality of penetration members, such as those found in conventional sex catalogs, adult book stores, and the like. 
     It is yet a further object of this invention to provide an enclosure for rendering the present apparatus easily portable. 
     It is still another object of the present invention to provide a portable housing for the therapeutic apparatus of the present invention which includes room for storing the disassembled components of the device and/or a plurality of interchangeable penetration members. 
     The present invention provides a therapeutic apparatus for relieving stress, tension, anxiety and sexual frustration in both men and women, while simultaneously providing sexual stimulation, gratification and pleasure. The sexual apparatus of the present invention includes an elongated rod having a resilient foam sleeve covering at least the front end portion thereof, and an elongated penetration sheath adapted to be removably received over at least the front end portion of the foam sleeve or collar. The penetration sheath is usually made from a rubber or latex-type material to simulate the feel of an erect male penis or the like. Furthermore, the foam collar also lends resiliency to even further approximate the true feel of an erect male penis. 
     The invention includes a motion-generating assembly which includes a first apparatus for horizontally reciprocating the elongated rod to drive the sheath-covered front end portion of the rod into and out of the user&#39;s selected body oriface, and a second apparatus for simultaneously producing an erratic up and down vertical component of motion for varying the angle of thrust and the angle of withdrawl of the sheath-covered end portion for substantially increased or enhanced results. 
     The invention also contemplates a housing or case for substantially enclosing all but a portion of the elongated rod of the present therapeutic apparatus to render it easily portable. The case may be adapted with a door or entrance for accessing the interior thereof and a plurality of different and distinct penetration sheaths may be stored therein or, alternatively, the disassembled components of the apparatus may be stored therein when not in use, or both. Even further, the casing may be provided with a sound-producing means such as a cassette deck, a tape player, a Walkman-type radio transmitter, or the like. The case may then have external speakers or an aperture for extending a cord to a pair of earphones for private listening. Even further, the enclosure may house a rechargeable battery pack or an AC adapter for running on direct current or DC power, or it may be equipped with only an electrical cord and plug for running an AC motor on AC power. 
     These and other objects and advantages of the present invention will become more fully understood after reading the detailed description of the preferred embodiments, the claims, and the drawings, which are briefly described hereinbelow.

FIG. 1 also shows the therapeutic apparatus 11 as including a variable AC electric motor 71, as hereinafter described with reference to FIG. 2. 
     FIG. 2 also shows a sectional side view of the therapeutic apparatus 11 of FIG. 1 in greater detail. In FIG. 2, the therapeutic apparatus 11 is shown as including the housing or case 11 including the base 15 having a lower surface 17 and an upper planar surface 19. A front panel 21 and a rear panel 25 are also included, and the front panel 21 includes the vertically elongated slot or rod aperture 23. A cover 27 includes a left side 29, a right side 31, and a domed or arcuately shaped top 33, and the cover 27 may be secured to the top and sides of the front and rear panels 21 and 25, by conventional fasteners such as screw-type devices or the like. The housing or case 13 has a hollow interior 35 and an elongated rod 37 extends through the slot 23 of the front panel 25 to access the exterior of the housing 13. 
     The elongated rod 37 includes a rear end portion 39 and a front end portion 41. At least one of the front end portion 41 and rear end portion 39 may be provided with a plurality of adjustment apertures while the other of the front end portion 41 and rear end portion 39 of the rod 37 may be provided with a single aperture adapted to receive an adjustable fastener or connector 43, such as a conventional screw, pin, or the like, for enabling the length of the rod to be selectively adjustable for controlling both the depth of penetration and the length of the rod 37 itself. In the preferred embodiment of the present invention, the rear end portion 39 of the rod 37 has a first diameter &#34;d1&#34; while the front end portion 41 has a second diameter &#34;d2&#34;, where &#34;d2&#34; &#34;d1&#34;. Still further, the front end portion 41 has a hollow interior whose inside diameter &#34;d3&#34; is approximately equal to the diameter of the rear end portion 39 (d3 d1) so that the rear end portion 39 can be telescopically received within the hollow interior of the front end portion 41 and moved longitudinally therein for aligning the apertures, inserting the fastener 43 and thereby selectively adjusting the length of the elongated rod 37. 
     In FIG. 2, the foam sleeve or collar 45 is shown as including a front end portion 44 and a rear end portion 46. In the embodiment of FIG. 2, the front end portion 44 of the foam sleeve 45 is shown as being closed while in the embodiment of FIG. 1, the front end portion 44 of the foam sleeve 45 was shown as being open since either is appropriate for use herein. In FIG. 2, the rear end portion 46 of the foam sleeve is open, as at 52, and the sleeve 45 is provided with a substantially hollow interior extending at least partially therethrough. The hollow interior of the foam sleeve 45 is generally cylindrical, and the open end 52 of the rear end portion 46 is adapted to receive the front end portion 41 of the elongated rod 37 therein, in a force-fit manner, in order to removably secure the foam sleeve 45 to the front end portion 41 of the elongated rod 37. Preferrably, the front end portion 41 of the rod 37 extends only partially through the foam collar 45 to lend even greater resiliency to the front end portion 44 of the sleeve 45. 
     A penetration sheath or member 47 is shown as having a head end or front penetration end 49 and a rear end portion 50. The penetration member 47 is conventionally of a cylindrical nature and generally has a hollow interior such that at least the rear end portion 50 of the penetration member 47 can be removably force-fitted over the front end portion 44 of the foam sleeve or collar 45 and positioned thereon so that it will not come off during use. The tightness of the fit is determined by the thickness of the foam collar 45 which is selected to accomodate a plurality of different and distinct penetration members 47, each having a similarly dimensioned, generally hollow, cylindrical interior portion having approximately the same inside diameter. The head end 49 of the penetration member 47 is also shown as including a head portion 165 to further facilitate the simulation, including both the look and the feel of an erect male penis. The reciprocal back and forth motion of the elongated rod 37 is indicated by the directional motion arrows 159 and 161, and the up and down movement is indicated by the directional motion arrows 158 and 160. 
     FIG. 2 shows, housed within the hollow interior 35 of the housing 13, the motion-generating assembly 51 which includes a horizontal drive assembly 53 and a suspension assembly 55 which is used to add a vertical component to the motion produced by the horizontal drive assembly 53, as hereinafter described. 
     The horizontal drive assembly 53 includes a drive shaft assembly 57 having a rotatable driven shaft 59 on which an eccentric wheel or disk 61 is mounted for rotation therewith. The eccentric wheel or disk 61 includes an elongated wheel slot 63 which passes through the center of the disk 61. Furthermore, on one side of the eccentric wheel or disk 61, a right pulley 65 is mounted, while a left pulley 67 is mounted on the opposite side of the disk 61 and over the rotatable drive shaft 59. Each of the pulleys 65 and 67 includes one or more radially-spaced apertures 94 which are adapted to receive a fastening device, such as a conventional threaded bolt 68, therethrough. The bolt 68 also passes through the elongated wheel slot 63 of the disk 61, and conventional fasteners, such as nuts, or wingnuts 69, are threaded onto the inserted end of the bolt 68 to secure the right pulley 65, eccentric wheel or disk 61, and left pulley 67 tightly together in a sandwich-like configuration. 
     The horizontal drive assembly 53 also includes a variable AC electric motor 71 having an electrical connector or cord 73 which is adapted to pass from the hollow interior 35 of the housing 13 to the exterior thereof via an outlet aperture 77. The cord 73 may include a rheostat 250 or the like for enabling the user to selectively control and vary the speed of the motor 71, as known in the art. The rheostat 250 includes a case 251, an elongated slot 253 and a sliding control button 255. The opposite end of the electrical cord 73 is provided with a conventional plug 75 which can be plugged into any conventional wall socket for supplying AC power to the motor 71, as known in the art. The motor 71 includes a motor mount 79 which may be fixedly secured by screw-type fasteners 81, or the like, to the bottom panel 15 of the enclosure 13. The electric motor 71 includes a motor drive shaft 83 which extends from both sides of the motor, and a left motor pulley 85 is mounted on one side of the motor drive shaft 83 while a right motor pulley 87 is operatively mounted on the opposite side of the motor drive shaft 83. Each of the motor pulleys 85 and 87 are mounted on the motor drive shaft 83 for rotation therewith. Each includes a drive belt or band 89, 91 fitted into the corresponding pulley groove of the right motor pulley 87 and left motor pulley 85, respectively. The opposite end of the pulley drive belt 89 is operatively carried by the grooves of a pair of driven pulleys 65 and 67 for rotating the driven shaft 59, as previously described. The driven shaft 59 mounts the right pulley 65, the eccentric wheel 61, and the left pulley 67 on the rotatable driven shaft 59 in a sandwich-type fashion via the fasteners 68 and 69, as previously described. Since the opposite portion of the drive belts 89 and 91 is operatively secured within the grooves of the driven pulleys 65 and 67, respectively, the rotation of the motor drive shaft 83 rotates the motor pulleys 65 and 67, which in turn drives the belt 91 to rotate the pulleys 65 and 67, which in turn rotates the driven shaft 59 and the eccentric disk 61 mounted therewith. 
     The hollow interior 35 of the case 13 is also shown as including a generally vertical support post 95 having a bottom end portion 97, which may include a rigid reinforcement rod 99 which is connected or anchored to the base panel 15 via a fastener or connector 101. The bottom end portion 97 of the support post 95 may be substantially hollow to receive the rigid reinforcement rod 99 therein. The support post 95 also includes an arcuately curved intermediate portion 103, which is preferably resilient or easily bendable, and a resilient top end portion 105 terminating in a top distal end 106. Preferably, the resilient top end portion 105 of the support post 95 is curved to bend forward in the direction of the elongated slot 23 and has a pair of opposed up-turned hooks 107 mounted on opposite sides of the resilient top end portion 105 spaced a predetermined distance to the rear of the top distal end 107. An inverted U-shaped yoke assembly 109 is suspended from the hooks 107, via elastomeric bands 123, as hereinafter described. The inverted U-shaped yoke assembly 109 includes a closed end 111 operably disposed between a left leg 113 and a right leg 115. An eyelet 107 is operatively carried by the opposite end of the left leg 113 (not shown in FIG. 2) and includes an eyelet 117 having a hollow interior or aperture 118 therein, while the right leg 115 includes an eyelet 119 having a hollow interior or aperture 120. 
     A pair of down-turned hooks 121 are disposed on opposite sides of the legs 113 and 115, and they&#39;re adapted to retainably position elastic members or rubber bands 123 whose opposite upper ends are retained in position by the up-turned hooks 108 and 107 of the top end portion 105 of the support post 95. A generally Y-shaped yoke 125 has a leg 127, a left arm 129, and a right arm 131. The right arm 131 is provided with an eyelet 133 having a central aperture 134 therethrough (not shown in FIG. 2), while the left arm 129 terminates in an eyelet 135 having a central aperture 136. 
     The hollow interior 35 of the housing 113 may also be provided with a storage area 137 located on the top surface 19 of the base panel 13 and, as shown in FIG. 1, it may be used to store a plurality of different and distinct interchangeable penetration members 47 or, alternatively, the disassembled rod-end of the apparatus, when not in use. Furthermore, one or more of the panels, such as the rear panel 25, may by provided with an access door 141 having a knob 142 or the like which can be openable to gain access to the hollow interior 35 of the housing or case 13. This will enable the user to remove the rod-like member for reassembly or to select a different and distinct one of the penetration members 47 desired for use at a particular time or for a particular purpose. Furthermore, the hollow interior 35 may include electrical sound producing devices such as a radio, tape deck, tape player, CD, or the like, which can feed the sound to the external area via speakers 145 or via an electrical connector 149 and an outlet port 147 to a pair of earphones 151. 
     The hollow interior 35 may also include a rechargeable battery pack 150 and/or an AC adapter 152 for powering a DC motor or, as in the preferred embodiment, the electrical cord 73 can provide electrical power from the wall socket and plug 75 directly to the AC motor 71 for operating same. The bi-directional horizontal motion arrow 153 shows the bi-directional, generally horizontal movement of the Y-shaped yoke 125 driving the elongated rod 37 and powered by the horizontal motion-generating assembly 53. The directional arrow 155 shows the rotational direction of the shaft 59, pulley 65 and disk 61, while the vertical bi-directional arrow 157 shows the motion of the inverted U-shaped yoke 119 suspending the horizontal drive assembly 53 via the suspension assembly 55. Directional arrows 163 show the direction of rotation of the pulley drive belt 91. 
     Lastly, the penetration member 47 is shown as including a bulbous head 165, an elongated cylindrical body 167 having an aperture or opening 168 in the rear end thereof for fitting the foam collar 45 into the hollow interior thereof. 
     FIG. 3 shows, in greater detail, the horizontal drive assembly 53 of FIGS. 1 and 2. In FIG. 3, the position of the drive shaft assembly 57 including the rotatable driven shaft 59, the eccentric wheel or disk 61, and the driven pulleys 65 and 67 are shown in solid lines in a position of forward thrust as indicated by the directional arrow 159 and, in a position of withdrawl as indicated by the directional arrow 161 in phantom lines. The corresponding components of the horizontal drive assembly 53 in the forward thrust position are indicated by the previously given reference numerals, while the components in the withdrawling position are indicated by the use of a prime symbol (&#39;) after the corresponding reference number. Since the driven shaft 59 is suspended from the top of the support post 95, it is free to move as the drive belt 91 rotates the pulley 65. The rotation of the pulley 65 turns the shaft 59 and hence the eccentric disk 61 mounted thereon. Since the driven shaft 51 is disposed along the longitudinal slot 63 of the disk 61 and spaced a predetermined distance from the center of said disk 61, it can be seen that as the belt 91 rotates, as shown by the directional arrow 163, the disk 61 rotates in a clockwise direction as shown by the directional arrow 155 causing the forward movement of the rod 39 during one half of the rotation cycle of the disk 61 and the withdrawl of the rod 39 during the opposite half cycle of rotation of the disk 61. It is by this method that the horizontal drive assembly 53 operates to reciprocally move the elongated rod 37 in a generally horizontal back and forth motion for thrusting forward for penetration and then moving backward for withdrawl. 
     FIG. 4 shows the overall motion generator 51 with the horizontal drive assembly 53 and the suspension assembly 55 in greater detail. It will be seen that as the electric motor 71 rotates the motor drive shaft 83, the motor drive pulleys 85 and 87 will be rotated therewith. The rotation of the motor pulleys 85 and 87 will rotate the drive belts 89 and 91, respectively, to drive the driven pulleys 65 and 67, respectively, of the drive shaft assembly 57. Since the eccentric disk 61 is sandwiched between the inside surfaces of the pulleys 65 and 67, and all are mounted on the driven shaft 59, the entire assembly rotates with the rotation of the motor drive shaft 83 and the position of the drive shaft within the elongated slot 63 and, in fact, the distance it is positioned away from the center of the disk 63 determines the length of the horizontal back and forth motion or stroke of the elongated rod 37 via the Y-shaped yoke assembly 125 as previously described. 
     It will be noted that the entire drive shaft assembly 57 is suspended by the suspension assembly 55. The hooks 107 on opposite sides of the top end portion 105 of the support post 95 are connected via rubber bands or suspension means 123 to the down-turned hooks 121 operatively disposed intermediate the legs 113 and 115 of the inverted U-shaped yoke assembly 109. Since the opposite ends of the legs 113 and 115 have their eyelets 117 and 119, respectively, mounted to the drive shaft assembly 57 via the insertion of the threaded member 68 through the eyelet apertures 118 and 120, respectively, the entire drive shaft assembly 57 is supported or suspended in space therefrom. The threaded member 68 is used to sandwich the pulleys 65, 67 and the disk 61 together, while the driven shaft 59 may be provided with a head at one end and an aperture at the opposite end adapted to receive a cotter pin or similar connection device 169 for securing the drive shaft assembly 57 and the suspension assembly 55 together. 
     FIG. 5 shows an exploded view of the horizontal drive assembly 53 of the present invention plus portions of the suspension assembly 55. In FIG. 5, the inverted U-shaped yoke 109 is shown as including a closed end 111, a left leg 113 and a right leg 115. The intermediate portion of each of the legs 113 and 115 are provided with an outwardly disposed pair of downwardly curved hook members 121 which are adapted to engage one end of the elastomeric or rubber band loop 123 while the opposite end is suspended from the top of the support post 95 as previously described. The opposite ends of the legs 113 and 115 terminate in a pair of eyelets 117 and 119 having hollow interiors or eyelet apertures 118 and 120, respectively. The apertures 118 and 120 of the eyelets 117 and 119 are adapted to be received over the elongated body portion 167 of the driven shaft 59 which is shown as having a head 165 and an aperture 168 in the opposite end of the elongated shaft 167. The shaft 59 is adapted to be received through the apertures 92 of the driven pulleys 65 and 67 as well as through the eyelets 117 and 119 before a fastening device, such as the cotter pin of FIG. 4, is passed through the aperture 168 to retain the drive shaft assembly 57 rotatably mounted on the driven shaft 59. The threaded members 68 are shown as being passable through the apertures 94 of the pulleys 65 and 67 and to secure the pulleys 65 and 67 on opposite sides of the eccentric wheel 61 in a tight sandwich-type configuration via wingnuts 69. 
     The driven pulleys 65 and 67 are shown as including a pair of oppositely disposed peripheral ridges 183 forming a hollow belt housing depression 185 therebetween as conventional with pulleys of this sort. Lastly, the Y-shaped yoke 125 is shown as having the leg 127 extending in a forward direction so as to be connectable to or integral with the distal rear end of the rear end portion 39 of the elongated rod 37 and a pair of oppositely disposed arms 129 and 131 each terminating in an eyelet 133, 135, respectively, and an eyelet aperture 134, 136, respectively. The eyelets 133 and 136 are also adapted to be engaged by the driven shaft 59 by the elongated central portion 167 passing through the apertures 134 and 136 of the eyelets 133 and 135, respectively, as were connected the eyelets 117 and 119 of the inverted U-shaped yoke 109. 
     It will be understood that the material used to form the various panels of the housing 13 can be any rigid material including plastic, wood, metal or the like and the cover 27 may include any similar material, although, in the preferred embodiment of the present invention, a generally transparent plastic material is contemplated. Any types of fastener means may be used, as conventionally known in the art, or substituted for any of the fastening means discussed herein. It will further be understood that the particular design, shape, function, and the like of the penetration sheath can be chosen from a wide plurality of such sheaths commercially available in any adult catalog, adult book store, or the like today. 
     The dimensions of the unit and the dimensions of the elongated front aperture, are not critical to the present invention and need only be sufficient to serve their intended functions. It will further be noted that the length of the stroke can be changed by increasing the radius at which the driven shaft 59 is positioned within the elongated slot 63. The length can also be selectively varied by the length adjustment means 43 on the elongated rod 37. The amount of up and down component of motion added to the horizontal motion can be varied by altering the resiliency of the support post or the elasticity of the rubber suspension bands 123. The material of the driven pulleys, the drive pulleys, and the eccentric disk can also be metal or plastic, and the motor may be AC or DC, although an AC variable speed motor was chosen in the preferred embodiment of the present invention. Similarly, various means can be used to drive the motors, as known in the art. 
     It will, of course, be recognized by those of ordinary skill in the art that various modifications, variations, substitutions, changes, and alterations can be made in the form, structure, detail, and method of operation of the present invention without departing from the actual spirit and scope of the present invention, which is limited only by the appended claims.
