FIELD OF INVENTION 
     This invention relates to chin up and pull up bars, and in particular to assemblies, systems, devices, and methods for clamping a pull up bar assembly, with multiple grip locations for performance of exercises, to both sides of a door frame above a doorway, with or without additional straps and cords supporting a suspended bar used for the performance of exercises; and stand-alone racks with straps and cords supporting a suspended bar used for the performance of exercises; and existing bars or structural members with straps and cords supporting a suspended bar used for the performance of exercises. 
     BACKGROUND AND PRIOR ART 
     Various types of exercise devices exist that can be used with a residential doorway. A common device used to perform pull-up or chin up exercises is constructed of a frame for which one part is placed above the trim of one side of the doorway, allowing a second part of the frame, which is wider than the doorway, to rotate down and rest against the trim on the sides of the doorway. The user&#39;s load is divided between these trim areas. This version has several flaws. First the load from the user typically causes the side decorative trim to be damaged by the frame load, even when mitigating devices are employed. A second flaw is that this mounting arrangement does not provide a positively secured device. There is possible inadvertent displacement of the first part of the frame that rests above the doorway, causing the frame and the user to unexpectedly fall, potentially injuring the user. Another flaw with this version is that, since the user portion of the frame is always opposite the door hinge side of the doorframe, and the door hinge is typically on the room-side of the doorway, the user is almost always performing exercises in the hallway. This can be a problem if the hallway is being used by others, or if the user prefers to use a room as the place of exercise. Another flaw is that there is a single point of failure of the device: should the door trim on one side of the door not be properly constructed to support load, or if it becomes compromised due to overuse, the device and user will fall if the said door trim fails. 
     Another prior art device requires the door to be closed, and an anchor is placed between the closed door and the door jamb. Attached to the anchor are elastic or inelastic straps with handles and foot loops for which the user, where the user leaning or suspending their body weight away from the anchor, creates resistance for executing a plurality of exercises. The user positions either their hand (hands) into handles, or foot (feet) into looped straps below the handles, which are attached to the straps. The anchor, straps, and user is typically located on the side of the doorway where the door does not swing, i.e., if the door swings into a room, as most do, the safest position to place the anchor and use the device is in the hallway, such that the anchor load causes the door to be pulled into the jamb, not away from it. The adjustment of the handles, which is needed to perform a plurality of exercises by changing the distance of the handle to the anchor point, is typically executed by utilizing a cam buckle or similar device cinched upon the strap with the handle at the halfway point, such that for every unit of distance the cam buckle is moved, the handle moves half that amount. The handles are typically rigidly attached to the strap, and the strap is continuous between the handles, such that the load from one handle is reacted by the load from the other handle. 
     This device also has several flaws. First, since the door must be closed to utilize the device, the amount of resistance the user can impart of the selected body part during an exercise is limited since the placement of the feet or hands is limited, i.e., the feet or hands cannot be placed under or past the door frame. Second, since there are individual straps for each appendage, there is large degree of freedom on a spherical course of each individual strap. This can put excessive strain on the joints of the appendage and negatively affect all but the most-fit user. Third, given the above-mentioned requirement for safe anchoring, the user may be required to use the device in a hallway, space permitting. If the user does choose to exercise on the room-side of the doorway, the user must open the door and remove the device to exit the room, and re-set up the device when returning to complete their exercise regimen. Fourth, should someone else inadvertently open the door while a user is exercising inside a room, the device will no longer be anchored potentially causing user injury. Fifth, the above stated means for which the device is adjusted, there is an inherent limitation on the overall distance the handles can be adjusted, limiting the overall range of exercises that can be performed with the device. Sixth, engagement of the user&#39;s foot (feet) into the foot straps can be difficult given that the looped strap is not rigid and moves when attempting to properly place the foot (feet) in to the loop. Seventh, since in most cases the handles do not rotate, strain can be placed on the wrists when executing exercises whereby the arms rotate about the elbows or shoulders. Eighth, since the strap is continuous from handle to handle and each handle load reacts with the other, if one hand or foot becomes inadvertently disengaged, the other hand or foot quickly moves downward due to gravity until a secondary mechanism, if it exists, stops further movement of the handle. This situation and subsequent quick handle movement has been known to cause user injury. 
     The invention presented here has all the positive benefits of pull up and suspended body weight exercises without the aforementioned flaws. 
     SUMMARY OF THE INVENTION 
     This invention relates to chin up and pull up bars, and in particular to assemblies, systems, devices, and methods for clamping a pull up bar assembly, with multiple grip locations for performance of exercises, to both sides of a door frame above a doorway, with or without additional straps and cords supporting a suspended bar used for the performance of exercises; and stand-alone racks with straps and cords supporting a suspended bar used for the performance of exercises; and existing bars or structural members with straps and cords supporting a suspended bar used for the performance of exercises. 
     A secondary objective of the present invention is to provide assemblies, systems, devices, and methods for clamping a pull up and cross pull up bars to both sides of a door frame above a doorway, which rigidly clamps to both sides of a doorway trim via a screw mechanism which creates tension between rigid and rotating portions of the frame. A user&#39;s bodyweight is reacted via frictional forces of the clamped frame on the wall, and the ledge bars on the trim of both sides of the doorway. The result is a very secure device to execute pull ups, chin ups, and other body weight exercises. 
     A third objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which allows the user to position their body directly under and beyond the attach point when utilizing the suspension bar, maximizing the resistance imparted when executing a plurality of different exercises. Exercises such as suspended arm and suspending leg push-ups directly under the attach point are possible. 
     A fourth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which consists of a single bar suspension bar whereby its degree of freedom is limited to single-plane rotational movement about the anchor point, conducive to efficiently executing strength, high intensity, plyometric, and other modes of exercise, while minimizing potential for user injury. 
     A fifth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which consists of a suspension bar that can be quickly and repeatedly adjusted a large distance from the anchor point due to the cam buckle/strap arrangement, and graduated marks on the straps. 
     A sixth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which allows the user to quickly and comfortably engage their feet onto the suspension bar via usage of a cushioned block between the foot or leg and suspension bar. 
     A seventh objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which consists of a suspension bar that can quickly be adjusted to be horizontal with the floor, facilitating equal loading of hands or feet during exercise. 
     An eighth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which consists of a suspension bar that freely rotates about the axis of the user&#39;s grip, minimizing strain on the wrists. 
     A ninth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which can be configured to be installed on standard (approximately 4½″) and load bearing (approximately 6½″) wall widths, or wall widths in that approximate range, as well as standard and wide door trim widths. 
     A tenth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which allows the user to quickly stow the bar and enter/exit the room of the doorway where the device is installed during exercise sessions. 
     An eleventh objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which allows the user to perform exercises on either side of the doorway 
     A twelfth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which can be securely affixed to a bar provided by others by wrapping around the bar, with the J hook secured onto the cam buckle. 
     A thirteenth objective of the present invention is to provide assemblies, systems, devices, and methods for providing pull up and chin up bars, which can be securely affixed to a standalone suspension exercise frame, which has a slot to receive the suspension bar J hook. 
     In this application, a pull up is performed when the user has hands placed on a bar, with the palms of their hands facing away from the user, and utilizes their arms, shoulders, and torso to elevate their body weight. A chin up is the same activity, with the exception that the palms are facing towards the user. An alternate version of a pull up, the neutral grip pull up, is when the hands are placed on parallel bars, with palms facing, to while utilizing their arms, shoulder, and torso to elevate their body weight. 
     Further objects and advantages of this invention will be apparent from the following detailed description of the presently preferred embodiments which are illustrated schematically in the accompanying drawings.

A left cross bar  20 L can be attached to footers  34  extending from angled legs  32  of the left M shaped bracket  30 L by fasteners  15 . An indented mid portion  36  of a right M shaped bracket  30 R can attach to a right end portion  14  of the main bar  10  by fasteners  15  that can include screws/bolts, nuts and washers. A right cross bar  20 R can be attached to footers  34  extending from angled legs  32  of the right M shaped bracket  30 R by fasteners  15 . Each of the cross bars  20 L,  20 R can have end caps  28  at outer ends. Cushions  18 , such as but not limited to foam grips and the like, can be wrapped about the cross bars  20 L,  20 R. 
     Referring to  FIGS. 1, 2 and 6-8 , the main pull up bar and cross bars assembly  1  can be attached to the clamp assembly  100  by two sets of vertical posts  130 ,  140 . The installer can select front side through-holes  25  in each of the cross bars  20 L,  20 R to screw fasteners  37  (such as bolts, screws), to pass into the selected front through-holes  25  and into the threaded openings in the rounded spacer  136  and are threaded into the bottom ends of the first set of vertical posts  130 . Similarly, the installer can select rear side through-holes  25  in each of the cross bars  20 L,  20 R to screw fasteners  37  to pass into the selected rear through-holes  25  and into the lower threaded openings in the tube inserts  146  and to screw fasteners  37  into through-holes  147  of vertical posts  140  and into side perpendicular threaded openings in the tube inserts  146 . The different through-holes  25  in the cross bars  20 L,  20 R can be selected based on the different wall thicknesses of the door frames that the clamp assembly  100  is to be clamped thereto. For example, 4½ and 6½ inch thick walls, or smaller or larger can be clamped with the clamp assembly  100 . 
     A first horizontal clamp ledge member  110  can be attached by fasteners  15  (such as screws/bolts, nuts and washers) fastening into through-holes  133  in the upper ends of the first set of vertical posts  130 . Similarly second horizontal clamp ledge member  120  can be attached by fasteners  15  (such as screws/bots, nuts and washers) fastening into through-holes  143  in the upper ends of the second set of vertical posts  140 . The upper ends of vertical posts  130 ,  140  can be closed off with end caps  138 ,  148 , respectively. Similarly, end caps  118 ,  128  can be closed off with end caps  110 ,  120 . Threaded bars/rods  150  with knobs  152  at one end and nuts and washers  154  at an opposite end can pass through through-holes and through slots in vertical post sets  130   140 , and be used for clamping the assembly  100  about the door frame. Bumpers, of a soft or semi-soft and non-marking material, can be installed on ledge bars  110  and  120 , for interface of assembly  100  to the wall  74  and trim  72 . 
     Referring to  FIGS. 3-8 , the installer can position the clamp assembly  100  with main pull up bar and cross bars assembly  1  about both sides of a door frame  70  above the door trim  72 , preferably against the wall surfaces  74  above the trim  72 . The installer can rotate the knobs  152  to so that the clamp assembly  100  equally applies pressure on both sides of the door frame  170  so that any load weight below the door frame is equally distributed on both sides of the door frame  70  and on the trim  72  on both sides of the door frame  70 . 
     The installation of the novel clamp assembly  100  with pull up bar and cross bar assembly  1  will now be described. 
     The users determines cross bar hole locations by measuring the thickness of the wall where the installation is desired. A 6½″ wide wall requires use of the outer cross bar holes, while a 4½″ wide wall requires use of the inner cross bar holes. For wall widths in between, the user may utilize one set of outer and on set of inner holes. The users determined the width. If trim is standard trim size (2½″ or less width) the user uses the lower set of through holes  133 . If trim is a wide trim size (2½″ to 3½″ width) the user uses the upper set of through holes  133 . 
     The user installs ledge bar  110  and hooks  50  to vertical posts  130  with fasteners and adds ancillary bumpers and caps. This subassembly is attached to the pre-assembled main pull up bar and crossbar assembly  1  in the holes selected above using rounded spacer  136  and fasteners. The user installs ledge bar  120  and to vertical posts  140  with fasteners and adds ancillary bumpers and caps. This subassembly is attached to the pre-assembled main pull up bar and crossbar assembly  1  in the holes selected above with fasteners. 
     The user installs a threaded rod  150  through the vertical posts  130  and  140 . The user installs knobs  152  at the end of two stud and fasteners. 
     User Installation of Pull Up Assembly 
     The user determines which side of the doorway they prefer to perform exercises. The user recognizes that vertical post  130  is to be oriented on this side of the doorway. 
     The user picks up assembly  100 , rotates vertical ledge bars  140  open, lifts the assembly such that the ledge bars  110  and  120  are past the door trim Lift Pull Up bar overhead placing ledge bars past the top of trim  72 , rotates vertical ledge bars  140  closed, and tightens knobs  150  hand tight. 
     The novel clamp assembly  100  with pull bar and cross bars assembly  1  has the following benefits.
     1. Attaches to both sides of door trim via rotating member clamping against a rigid member.   2. Attaches to both sides of door trim, providing equal loading onto said door trim   3. Includes screw mechanism that positively attaches the apparatus to the door frame eliminating the potential for inadvertent un-attachment   4. Includes two screw mechanisms that provide a progressively increasing vertical Frictional Force (F f ) between the apparatus and the wall with increasing torque input, proportionally reducing the load imparted onto the door trim (F t ), reference  FIG. 21 .   5. Includes a pull up bar used for narrow/wide grip pull ups/chin ups that is raised above two cross bars which is used for normal grip (palms facing) pull ups   6. Allows the user to perform pull-ups/chin ups in a bidirectional fashion (i.e. the user can face into or out of the room where the doorway is positioned)   7. Provides slots for which suspension straps can be positively attached without inadvertent removal during normal use   8. Provides slots positioned such that it distributes the suspension strap downward load to a point nearly directly above the partially reacting wall trim   9. Provides two hooks for quick stowage of the suspension bar while the Pull Up bar is still installed.
