     FIELD OF THE INVENTION 
     The present invention relates generally to an apparatus to assist users in entering and exiting a bed. 
     BACKGROUND OF THE INVENTION 
     Individuals with physical disabilities or with limited endurance, such as the elderly, know all too well of some of the difficulties that they encounter in daily life. One (1) of these tasks is the simple act of entering and exiting a bed. Disabled users have other aids throughout their homes such as railings on stairways; grab bars in bathrooms, and even mechanical assisted chairs, but nothing to help them when entering and exiting a bed. Such activity is further complicated by the low nature of many beds and the fact that bones and muscle groups are stiff when getting up in the morning. Similar problems are faced by those who suffer from back pain as well. Accordingly, there exists a need for a means by which easy and ready assistance can be provided to enter and exit a bed. The development of the apparatus described herein fulfills this need. 
     There have been attempts in the past to invent assist mechanisms to help individuals enter and exit a bed. U.S. Pat.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within  FIGS. 1 through 3 . However, the invention is not limited to the described embodiment and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. 
     The present invention describes an assist handle for beds (herein described as the “apparatus”)  10 , which provides a simple yet effective means of assisting a person the getting in to and out of a bed  100 . The apparatus  10  generally comprises an outer housing  20 , a handle  30 , and a mounting plate  40  which is attached thereto a bed frame  105 . 
     Referring now to  FIGS. 1 and 2 , environmental views of the apparatus  10 , according to the preferred embodiment of the present invention, is disclosed. The apparatus  10  is preferably made of a durable, rigid material such as metal, thermoplastic, or the like. The handle  30  is approximately three (3) feet long and rotates and locks in various positions. The apparatus  10  is envisioned to reside in at least three (3) positions: a lowered, generally horizontal position (see  FIG. 2 ); a raised, generally vertical position (see  FIG. 1 ); and an intermediate configuration (not shown). Although illustrated comprising three (3) positions, it is understood that the apparatus  10  may be introduced comprising incremental position changes throughout a range of motion and as such should not be viewed as a limiting factor of said present apparatus  10 . The mounting plate  40  provides a means of attaching the apparatus  10  thereto a bed frame  105  via a plurality of mounting fasteners  50 . 
     Referring now to  FIG. 3 , a section view taken along section line A-A of the apparatus  10 , according to the preferred embodiment of the present invention, is disclosed. The apparatus  10  comprises an outer housing assembly  20  and an inner housing assembly  60 . The inner housing assembly  60  is attached thereto the mounting plate  40  via an assembly fastener  54 . The assembly fastener  54  is preferably a standard mechanical fastener such as a bolt or the like. An assembly fastener aperture  56  is located therethrough the center of the mounting plate  40  and therein the center of a rear surface of the inner housing assembly  60 . Once the assembly fastener apertures  56  are aligned, the assembly fastener  54  is threadingly inserted therethrough, thus fastening the inner housing assembly  60  thereto the mounting plate  40 . The outer housing assembly  20  rotatingly attaches thereto the inner housing assembly  60 , thus enabling said outer housing assembly  20  and handle  30  to rotate thereabout said inner housing assembly  60 . The inner housing assembly  60  comprises an inner tube  66  which outwardly extends therefrom the center of said inner housing assembly  60 . The outer housing assembly  20  comprises an outer tube  22  which is located therewithin the center of said outer housing assembly  20  which further comprises a diameter sufficient to receive the inner tube  66  when inserted therein. The outer housing assembly  20  is attached thereto the inner housing assembly  60  via an end fastener  24  which threadingly attaches thereto the inner tube  66 , thereby enabling said outer housing assembly  20  to freely rotate thereabout said inner tube  66 . The apparatus  10  further comprises a means to lock the outer housing assembly  20  and handle  30  therein a preferred position, thereby providing a stable support thereto a user. A generally circular positioning dial  62  is located thereabout the base of the inner tube  66  and provides a means of positioning and locking the outer housing  20  via at least three (3) position notches. A first notch  63  is located thereabout a “twelve o&#39;clock” position and locks the handle  30  therein the raised position. A third notch  65  is located thereabout a “three o&#39;clock” position and locks the handle therein the lowered position. A second notch  64  is located thereabout a midway point and locks the handle therein the intermediate position. A lever  26  is provided to engage therewithin the notches  63 ,  64 ,  65  at a desired position. The lever  26  is hingedly attached thereto the outer housing assembly  20 . The handle  30  is rigidly attached thereto the outer housing assembly  20  and further comprises a grip portion  32  thereon a distal end which provides a secure, comfortable gripping surface thereto a user. A rod  36  is located therewithin the handle  30  and provides an actuating linkage thereto the lever  26  via an up and a down motion. A first spring  38  is located thereon a lower end of the rod  36  which applies a constant compressive upward force thereupon said rod  36 . When a user engages a release button  34  located thereon an upper end of the rod  36  by applying a downward force thereon, the rod  36  moves in a downward direction, thereby engaging the lever  26  via a lever actuator  37 . The lever actuator  37  applies a downward force thereupon a free end of the lever  26  thereby lifting the engaging end of said lever  26 , which is in contact therewith the desired notch  63 ,  64 ,  65  via the hinge  28 . Once the lever  26  is free therefrom the desired notch  63 ,  64 ,  65  the outer housing assembly  20  and the handle  30  are free to rotate therearound the inner housing assembly  60 . The hinge  20  is preferably a spring-loaded hinge which naturally tends to force the engaging end of the lever  26  to be in contact therewith the positioning dial  62  when the release button  34  is not engaged. As the handle  30  and outer housing assembly  20  are rotated, the lever  26  will naturally engage therewithin the next approaching notch  63 ,  64 ,  65  as said lever  26  traverses the positioning dial  62 . The apparatus  10  further comprises a second spring  67  which is permanently attached therebetween the inner tube  66  and the outer tube  22 . The second spring  67  provides a compressive force thereupon the outer housing assembly  20  when the apparatus  10  is in the lowered position, thus when in said lowered position and the release button  34  is engaged the handle  30  will naturally begin the approach the raised position. The second spring  67  provides a means to assist a weak or physically challenged user with changing the position of the handle  30 . To maintain the safety of the user, the handle  30  is unable to automatically rise higher than the intermediate position due to the lever  26  naturally engaging the second notch  64 . Although illustrated comprising a positioning dial  62  further comprising a plurality of notches  63 ,  64 ,  65 , a manually actuated lever  26  to provide the locking means thereto the handle  20  and outer housing  20 , and a release button  34  to manually actuate the lever  26 ; it is understood that various other locking and releasing means are contemplated, such as spring-loaded pins, interconnecting gears, or the like and as such should not be viewed as a limiting factor of the present apparatus  10 . The mounting plate  40  is preferably a durable rigid material comprising a plurality of mounting fastener apertures  52  therethrough. Corresponding mounting fastener apertures  52  are required therein the bed frame  105  in a position suitable for attaching the apparatus  10  via the mounting fasteners  50 . The apparatus  10  is illustrated comprising a mounting plate  40  and mounting fasteners  50  which are standard hardware fasteners and attached thereto a wooden bed frame  105  which would simply require mounting fastener apertures  52  to be drilled therein in order to attach said apparatus  10  thereto said bed frame  105 . It is further contemplated that the mounting plate  50  may attach thereto a metal bed frame  105  in a similar manner comprising alternate mounting fasteners  50 , such as clamps or the like. 
     It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the apparatus  10 , it would be installed and utilized as indicated in  FIGS. 1 and 2 .
