CONTINUATION-IN-PART  
       [0001]    This application is a continuation-in-part of my U.S. application Ser. No. 09/757,234 entitled “Device to Assist in Relaxing and Relieving the Stress of a Subject” filed on Jan. 9, 2001. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    The instant invention relates to a device which provides continuous gentle moving contact with the human body for the purpose of relieving stress and enhancing relaxation.  
         BACKGROUND OF THE INVENTION  
         [0003]    There are a variety of devices used to message the human body and which provide many different modes of body contact. These devices exhibit a wide range in the amount of force or pressure that is exerted on the body so that a user may experience sensations ranging from a true message to a light caress. Many of the devices provide intermittent contact, some involve large and cumbersome framework and others provide a small contact head that makes minimal contact with the body.  
           [0004]    Ferguson, in U.S. Pat. No. 3,672,357, teaches a massage apparatus consisting of a rectangular frame positioned over a bed and supporting a carrier that moves in a prescribed repetitive path along a track. The carrier holds a massage applicator which makes contact with the body of a person lying prone on the bed. In one embodiment a motor drives a threaded rod in contact with the carrier causing the carrier to move back and forth over the body. The massage applicator is in the form of dangling cords which may have different degrees of stiffness. The applicator sweeps across the entire length of the body and since the body has many contours there is intermittent contact and varying pressure. Several embodiments are described, all of which require another person to turn the device on and off since the subject is lying under the frame. The subject would have to crawl under the frame or have someone lift the frame so he can lie down within the massaging area and lift it again when he chooses to rise.  
           [0005]    U.S. Pat. No. 4,228,794 to Boller discloses a hand held massager requiring that one person, the user, hold the device and give the massage to another person, the subject. The device has a series of protruding fingers that alternately make contact with the back of the subject This device is air cooled so the user can hold it for prolonged periods. The user can vary the pressure or degree of massage as desired. Only a small part of the body of the subject is contacted at any time and this device is not designed to provide a light or soothing touch.  
           [0006]    A scratching and petting device for household pets is taught by Della Vecchia in U.S. Pat. No. 4,872,422. A wall mounted vertical base has a foldable horizontally extending petting arm that can be adjusted to different heights according to the size of the animal. The petting arm is biased for an up and down movement. It is suspended at a point about one third of its length from the vertical base by one end of a flexible cable or cord with the other end of the flexible cable being tied to a bracket on the vertical base. The flexible cord permits the up and down motion of the petting arm which is initiated when an electric eye is activated by the close proximity of the animal. The animal learns to position itself so that the stiff hand-like portion at the end of the arm moves vertically as it contacts the head or back of the animal, depending on the height at which the arm is set. This device has only a finger sized contact with the animal&#39;s body and would not be very soothing if used by a human. A human would have to move around to have a device such as this scratch different parts of his body and this would not be very relaxing. When not in use the petting arm can be moved to a rest position by manually removing the cord and allowing the petting arm to pivot to a downward position along the vertical base.  
           [0007]    Persaud teaches another type of back massager in U.S. Pat. No. 4,984,568. This device is clamped to the side rail of a bed and is for massaging an individual&#39;s back. A vertical rod is equipped with a hydraulic assembly so it can be raised or lowered. A horizontal arm, also with a hydraulic assembly, can move a massage head vertically and angularly about the back of the subject. The massage head can be fitted with rollers or resilient fingers. A control box is used to program the path of the massage head and also has a timer to set the duration of use. The head can also be used to dispense lotion. The subject may also cause the head to move and to dispense lotion by means of a joy stick. The need to constantly move the massage head with the joy stick removes any pleasure of just relaxing. This device is specifically for providing a message, and is not designed for a light touch. The subject must also be positioned just under the massage head for best results.  
           [0008]    An automatic body massaging device is taught by Tarlow et al. in U.S. Pat. No. 5,016,617. The small base of the device fits between the mattress and box spring of a conventional bed. A vertical column attached to the base supports a substantially oval track. A roller moves around the track and carries a leather piece cut into strips. The strips have hook and loop type fasteners at their ends to which various weights may be attached. The weighted strips provide the massage.  
           [0009]    A battery powered motor moves the roller around the track. As the roller moves around the track the strips alternately make contact and lose contact with the back of the subject. Unless the device is disconnected from the bed the track is always positioned directly over the sleeping surface causing the subject to duck under the track to lie down and to be careful not to hit the track when rising. Depending upon the position of the roller when the device is turned off, the strips may remain directly over the bed and in contact with the subject whenever the subject is on the bed. The subject must turn the device on before lying down and rise to turn it off or have another person present for assistance.  
           [0010]    A back massaging apparatus that rests on a bed or massage table is disclosed by Chapman in U.S. Pat. No. 5,582,582. A rectangular frame is supported on the table by means of four telescoping legs. A cross rail moves back and forth along the side rails of the frame by means of a motor which drives a chain loop positioned over each side rail. The cross rail carries a massaging unit containing four rotatable heads each having downwardly extending fingers which may be rigid or soft. A second motor turns the heads and moves the unit back and forth over the cross rail. This massager must be positioned over the subject once he is lying on the table, so there is a need for another person for assistance. The unit appears to require a fairly rigid flat surface and a bed may not offer sufficient support thus making a special massage table a necessity. The spring activated up and down motion of the massage fingers provides a substantially forceful massage and will not give the light touch required for relaxation or sleep induction. The device would have to be lifted away from the table before the subject could rise.  
           [0011]    In U.S. Pat. No. 6,074,353 Helmer discloses a device designed to caress or tickle the body. A floor stand or base of the device rests on the floor. A vertical axle is supported by the floor stand which has a central channel into which the vertical axle is situated and in which it is permitted to rotate. A horizontal support rod is attached to the vertical axle by means of a clamping device and is rotated with the vertical axle. The vertical axle rotates by communication with a co-axial gear which is rotated by means of a stationary motor, a gear and a belt. The motor can rotate the gear assembly clockwise or counterclockwise. Strips of a soft flexible material such as feathers, cloth or rope are attached to the horizontal support rod and move in a circular path as the vertical axle rotates. The height of the horizontal support rod can be adjusted along the vertical axle by adjusting the clamping device, but the vertical axle is of fixed length. A control box enables the subject to change the speed and direction of rotation and to stop and start the motor. As the horizontal support rod moves in its circular path the strips of material alternately are in contact with and are out of contact with the back of the subject. The subject has to control the device and must press the stop button to turn it off.  
           [0012]    Most of the prior art devices require the assistance of another person in using the device because they must be placed near or over the subject while the subject lies prone and the devices must be turned on and off manually. If the subject has to activate and deactivate the device himself it is impossible for the subject to relax completely or to fall asleep while the device is in use. Many of the devices use soft flexible strips of material. Other prior art devices have massage arms or elements that move in such a manner that they alternately move off and on to the back of the subject interrupting any soothing sensation the device may provide. The prior art devices that are attached to or rest on the bed during use must be removed to some other location in order to use the bed for sleeping. Some of the prior art devices have heavy clumsy frames that must be set on the bed and then removed. These devices are quite large and require considerable storage area.  
           [0013]    There is a need for an automatic relaxation inducing device that can be utilized by the subject alone. There is a need for an automatic relaxation device that maintains constant contact with the body of the subject for maximum relaxation. There is a need for a device that enables the subject to fall asleep during use by automatically shutting off after a pre-set time period. There is a need for a relaxation device that can be placed in close proximity to a bed such that most of the base lies under the bed and out of the way and where the base is sufficiently stable to support the device when not in use.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0038]    The device  10  of the instant invention is shown in FIG. 1. It may be placed on any stable horizontal planar surface such as a bed-side table or floor so that the subject may utilize the device  10  while lying prone on a bed or massage table (not shown). The device  10  may be supported by a base  11  and a height-adjustable vertical support column  12 . Such height adjustable supports are well known in the art. One type of height adjustable support may have nested cylindrical segments and an adjustment knob  13  so that the exact desired height may be easily attained. The base  11  may be sufficiently sized and weighted such that the device may be quite stable whether placed adjacent to a bed or free standing.  
         [0039]    A motor  46  may be rotatably mounted at a pivot point  47  situated at the top of the vertical support column  12 . The there may be a cam  48  that may be revolved by a gear assembly  50  and drive shaft  49  activated by the motor  46 . A follower  51  may communicate between the cam  48  and a pivot  52  affixed to the vertical support column  12 . Activation of the motor  46  may cause the cam  48  to revolve and the follower  51  to move with it causing the motor  46  itself to rotate in a back and forth motion. The shape of the follower  51  may determine the degree of rotation of the motor  46 . See FIG. 9.  
         [0040]    The motor  46  may be contained within a housing  14  that may rotate with the motor  46 . There may be ventilation openings  15  in the housing  14  to assist in the venting of any heat that may be generated by the motor  46 . One or more control switches  16  may be mounted on the exterior of the housing  14  to activate and deactivate the device  10 . An electric cord  17  may depend from the housing  14  when an electric motor is used, but a battery powered motor may also be utilized.  
         [0041]    A sweep arm  18  may be connected at its proximal end to the motor  46  so that it sweeps back and forth as the motor  46  rotates. The sweep arm  18  may pass through an opening  54  in the housing  14  and extend horizontally and outwardly from the motor  46  and the housing  14  for a considerable distance. There may be a series of contact members  20  depending from the distal end  19  of the sweep arm  18 . The height of the vertical support column  12  may be adjusted so the contact members  20  make full and continuous contact with the back  27  of the subject  26  when the vertical support column  12  is placed adjacent to the bed and the subject lies prone thereon.  
         [0042]    The contact members  20  may be semi-rigid but pliable so as to feel like another person is moving his or her fingers and/or fingernails back and forth over the subject&#39;s back  27 . There are many polymeric substances, such as a variety of plastics known in the art, that may be used for this purpose. Lighter and more flexible materials may also be used, but such materials may provide a different sensation.  
         [0043]    The contact members  20  may be affixed to the sweep arm  18  in more than one manner. One such manner may be to utilize a contact unit  22  as seen in FIG. 2. The contact members  20  may be permanently affixed to a rod  23  which is shaped for reversible retention within a similarly shaped slot  25  in the sweep arm  18 . The rod  23  in cross section, and the slot  25  may be in the shape of an inverted trapezoid  24 . The rod  23  may slide into the slot  25  to be held there securely, but may also be easily removed and another contact unit inserted. This structure may enable one contact unit  22  to be easily exchanged for another contact unit  28  that may have contact members  29  of another shape or size and which may provide a different sensation when moved across the body. See FIG. 6. The use of a semi-rigid polymeric material may enable the contact members to be made in a variety of shapes and angles.  
         [0044]    In an alternate manner the contact members  20  may be permanently affixed to a different form of sweep arm  43  as seen in FIG. 8. Individual contact members  20  may be threaded through channels  55  in the distal end  45  of the sweep arm  43  and may be held in place by fasteners  44 . When this form of sweep arm  43  is used, more than one type of contact member may be individually threaded and fastened along the distal end  45  of the sweep arm  43 , or all of the contact members may be the same. The contact members may be selected and exchanged as per the wishes of the subject, or the entire sweep arm  43  with contact members  20  attached may be removable from the motor  46  and exchanged for another sweep arm with different contact members.  
         [0045]    The contact members  20  may have bends at their ends  21  like fingernails as seen in FIGS. 1  and  2 , which may better simulate the feeling of fingernails stroking the back of the subject, or the contact members  29  may be straight, as seen in FIG. 6, which may provide a slightly different sensation during use. As noted above, other shapes and angles may be possible.  
         [0046]    When the device  10  is activated the sweep arm  18  may be caused to sweep back and forth, by means of the cam  48  and follower  51 , through an arc A-B, seen in FIG. 3. Arc A-B may be from 30° to 50° to insure that the contact members  20  may be in constant contact with the back  27  of the subject  26 , but a wider angle may also be utilized as noted in FIG. 5. The starting position F of the sweep arm  18  may be seen in solid lines and the outer position E of the sweep arm  18  may be seen in dotted lines. While the sweep arm  18  is moving back and forth the contact members  20  may simultaneously be made to oscillate through an arc C-D seen in FIG. 4 by means of an oscillator (not illustrated) also associated with and activated by the motor  46 . The subject  26  may elect to utilize only the sweeping mode (FIG. 3), or both the sweeping mode and the oscillating mode (FIG. 4) at the same time. Each selection may provide different sensations on the back  27  of the subject  26 .  
         [0047]    A second embodiment  30  of the device may be is seen in FIG. 7. A housing  35  may be rotatably supported atop an alternate type of height-adjustable vertical support column  32  communicating with a somewhat different base  31 . In this embodiment, the vertical support column  32  and the base  31  may form an L-shape that may enable the base  31  to be positioned entirely under a bed (not shown). This form of base may be out of the way and not take up floor space near the bed, yet it may still provide ample support and stability for the device when in use or when stored away from the bed. The vertical support column  32  may be composed of nested cylindrical segments that may be adjusted by means of spring activated buttons  33  that may extend through cooperating openings  34 . An electric cord  38  may extend through an opening  37  at the bottom of the vertical support column  32 . Methods are well known in the art to have an electric cord pass through an adjustable column. There may be a second cord  41  extending from the housing  35  to a control box  39 . A timer  53  may be contained within the control box  39  so that the device  10  may be activated for specific periods of time and may thereafter shut off automatically. Such timers are well known in the art. The cord  37  may be long enough so that the control box  39  may be disposed on the bed so the subject  27  may be able to turn on the device  30 , set the timer  53 , and select the desired mode of motion. He or she may also change any of the settings without having to change position or rise from the bed. The control box  39  may contain all necessary dials or buttons  40  to accomplish the desired settings. In the alternative, the selections may be made using a similar control box that may utilize remote control means (not shown) and may negate the need for the second cord  41 . There may be ventilation openings  42  in the housing  35  to assist in venting any heat that may be generated by the motor (not shown) within the housing  35 .  
         [0048]    To utilize the second embodiment  30  the subject may position the base  31  under the bed, make any necessary height adjustments, take his or her place on the bed and, with the control box  39  at hand, set the timer and desired mode of motion of the sweep arm  36  and just relax. When the selected time period is concluded the timer  53  may automatically cause the device to be turned off. If the subject does not fall asleep he or she may change the settings at any time. If the controls are affixed to the housing  14  as illustrated in FIG. 1 in the first embodiment  10 , the selections may be made before the subject lies down on the bed. All of the settings may still be made by the subject  26  without the need for the assistance of a second person. Both embodiments  10  and  30  may be quite portable, easily moved from place to place, and just as easily placed against a bed for maximum contact with a prone subject.
