     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
     Portable multi-purpose exercise devices which use elastic bands for resistive training are well known in the art. Likewise, large gym systems with multiple stations for multiple users are also abundant in the field. What is needed is a modular and portable multi-function multi-user exercise device which is separable into different components for different exercises so that a number of people can exercise at the same time by taking different components and performing different exercises with the components. The prior art fails to produce such a versatile exercise device. 
     U.S. Pat. No. 6,409,640, issued Jun. 25, 2002 to Cournoyer, describes an upper body exercise device having a pair of arcuate posts having lower footrests for resting on the ground, and a U-shape spacer bar, mounted to the top ends of the arcuate posts for free abutting against an upright wall. The two posts therefore remain substantially parallel to each other and to the upright wall. The posts are provided with notches distributed along their length, in a horizontally registering pair of which a push-up bar may be inserted for support of the push-up bar at a selected height over ground. The exerciser takes minimal ground space, yet allows many different types of exercises to be performed by an individual. 
     U.S. Pat. No. 1,104,505, issued Jul. 21, 1914 to Holworthy, provides a horizontal bar exercise apparatus which can be fitted in private houses. The apparatus comprises a base, standards projecting therefrom, a horizontal exercise bar connecting the standards and bracing members. 
     U.S. Pat. No. 5,536,222, issued Jul. 16, 1996 to Banda et al, shows a portable upper body exercise device designed to be used with a rod or a bar. The exercise device is lightweight and detachable. It does not require clamps or screws to secure it to a tabletop. 
     U.S. Patent Application #20090062087, published Mar. 5, 2009 by Poppinga, indicates an adjustable exercise apparatus that comprises a support component, first and second actuation elements, and first and second straps. The support component can be a belt or vest, for example, and can includes first and second ends that can be interconnected to form the support component in a loop. The first and second actuation elements are disposed along the support component and can be used to engage a portion of the respective first and second straps. Distal ends of each of the first and second straps can be engaged by a user for performing an exercise. In this regard, the straps can be at least partially elastically deformable. Further, the first and second actuation elements can be used to adjust the lengths of the straps to alter the tensile force exerted by the straps during exercise. 
     U.S. Patent Application #20070087920, published Apr. 19, 2007 by Dachraoui et al, puts forth a portable exercise device which has a generally rectangular, box-like main body in two portions, hinged together for opening and closing and having a storage area within. Recessed areas operable for attaching suitably equipped resistance tubing are disposed in an array that enables a variety of exercises. 
     Two U.S. Patent Applications, #20060160682 published Jul. 20, 2006 and #20060030463 published Feb. 9, 2006 by Maloy et al, concern a training device for exercising muscle groups of the entire body which comprises a portable rotating base which may have resistance bands attached for exercising the arms while twisting the body. 
     U.S. Patent Application #20030083178, published May 1, 2003 by Gilman, illustrates a portable functional training resistance apparatus used to exercise, rehabilitate and promote muscular strength and flexibility throughout the entire human body and a method for its use. This apparatus comprises a rigid base with a recess, strong enough to bear the weight of an adult exerciser who is standing, sitting, leaning, laying or vigorously moving about said base while performing exercises. The base is designed to receive various adaptors in the recess for the user to stand, sit, lean or lay on while performing exercises. The base has a plurality of attachment points, strategically placed on opposite sides of the recess, used to receive a means of resistance for exercise movements where added resistance is desired. 
     U.S. Pat. No. 6,186,930, issued Feb. 13, 2001 to Ignaczak, is for a push-up trainer having a base and a pair of handgrip assemblies. The handgrip assemblies are each slidably mounted to the base, allowing for lateral movement of the handgrips. Each handgrip assembly allows for rotation of each handgrip around a vertical axis and around its horizontal lengthwise axis. Each of the sliding and rotational motions may selectively be allowed or locked out using a spring biased pin. 
     U.S. Pat. No. 7,125,367, issued Oct. 24, 2006 to Steams, shows a multi-purpose exercise apparatus. The exercise device includes a frame, and left and right force receiving members movably mounted on the frame. The force receiving members are selectively linked to one another to facilitate a first mode of exercise, wherein a person&#39;s hands or legs are repeatedly moved toward and away from one another. When so linked, the force receiving members may alternatively be biased toward one another or away from one another. The force receiving members may be decoupled to facilitate a second mode of exercise, wherein a person stretches and/or leans forward and then returns backward. 
     U.S. Pat. No. 5,226,868, issued Jul. 13, 1993 to Montgomery, claims an exercise device including a push-up board and two push-up handles. The two C-shaped push-up handles are mounted along various positions of the push-up board. Only one end of the C-shaped handles is located within symmetrically-spaced holes of the push-up board. Since only one end of the C-shaped handle is secured within the board and with the shape of the inserted handle end being round, the C-shaped handles are rotatable about the anchored end to provide a vast array of movement and varied exercise routines. A position most comfortable for the user is obtainable by rotation of the handle about the one end located in the push-up board. Numerous pre-set positions are available for doing push-ups to obtain a maximum health benefit from basic push-ups. Further, an adjustment is provided for maximum strength development and wrist comfort when doing difficult push-ups through a series of wide to narrow hand separation positions. 
     U.S. Pat. No. 5,205,802, issued Apr. 27, 1993 to Swisher, illustrates an exercise apparatus for providing improved muscle conditioning via push-ups or similar exercises. The apparatus comprises an elongated body with end supports and two rotatably affixed hand grips. The elongated body has a plurality of pairs of bushing lined holes. Each hole of each pair is equally spaced from the elongated body&#39;s vertical centerline. The hand grips are rectangularly shaped having a pin extension that slidably and rotatably fits in the body&#39;s bushing lined holes. The top horizontal portion of the rectangle is an ergonomically shaped handle. The pin and, consequently, the hand grip are locked into place in the body via a spring clip which engages the pin at its free end. The spring clip engages the underside of the body such that the hand grips cannot be withdrawn from the body until the clip is removed. While being used, the user grabs the ergonomically contoured handles and performs a push-up or similar exercise. The invention allows the user to properly space the hand grips for maximum comfort and variation of exercises. While pushing up and returning down, the user can rotate his hands and wrists through a mechanically limited range of motion as demanded by the body&#39;s natural tendency to do so during such an exercise. 
     U.S. Pat. No. 1,402,179, issued Jan. 3, 1922 to Piscitelli, relates an exercising harness which is worn on the back of the user and which has a series of elastic ropes slidably contained within cord holder on the back of the harness. The group of ropes has a handle at each end.

     DETAILED DESCRIPTION OF THE INVENTION 
     In  FIGS. 1-15 , a portable multipurpose modular exercise device  10  is separable into multiple different modular exercise components by pin  11  connections, including a base stand  20 , base pads  30  used with the entire device  10  or just the base stand  20  or separately on the floor, an auxiliary cross bar  50  used with the base stand  20  or on the floor, and an upper cross bar  40  supported by vertical tower posts  41  adjustably attached to the base stand  20 . The modular exercise components are usable simultaneously by a number of different users working out on different modular exercise components separated from the same device, as shown in  FIGS. 4-10 . 
     In  FIGS. 1-4 , a base stand  20  comprises two spaced vertical base posts  21  interconnected by at least one horizontal support bar  27  removably attached between the two vertical base posts  21  and connected to each of the vertical base posts  21  by removable pins  11 . The base posts  21  comprise a series of vertically spaced mating paired support brackets  22  to receive and support a modular component supported horizontally between one of the pairs of support brackets  22  at a time. The base posts  21  also comprise at least one pair of aligned horizontal brace brackets  26  with at least one on each of the base posts  21 , extending between the base post  21  and an external vertical surface. The horizontal brace brackets  26  rest against the external vertical surface for support at least at the top of the base posts  21  and to space the base post away from the external vertical surface to allow a user to stand between the base posts  21 . The pair of aligned horizontal brace brackets  26  further comprise a support bar  25  horizontally resting against the vertical surface (wall) to spread the load over two or more wall studs to prevent the brace brackets from going through the wall. Additionally, the base legs  32 ,  33 , and  34  (base front leg, base side leg, and base back leg, respectively) stabilize the device  10  to keep it from tipping over or sliding. The base back foot  35  attached to the base back leg rests against the vertical surface (wall) for added stability after seating in the leg bracket  37  and secured by a pin  11 . 
     In  FIGS. 1 ,  2 , &amp;  4 , a modular auxiliary cross bar  50  is removably attached by loop pins  11  between one pair of mating paired support brackets  22  at a time on the base posts  20 . In  FIGS. 5 &amp; 6 , the modular auxiliary cross bar  50  is alternately separated from the base posts  20  and positioned on a floor surface resting on a pair of downwardly extending feet  51 , one at each end of a rigid horizontal bar  52 .  FIGS. 1 ,  2 ,  4 ,  5 , &amp;  6  show the auxiliary cross bar  50  comprising the rigid horizontal bar  52  having a pair of hand grips  54  slidably and pivotally attached to the auxiliary cross bar  50  so that the hand grips  54  may slide along a ridge  53  in the top of the auxiliary cross bar  50  at a selected angle for sliding exercises (as shown in  FIGS. 2 ,  5 , &amp;  11 ), or may alternately be individually secured to the auxiliary cross bar  50  in a desired position and desired angle for non-sliding exercises using removable loop pins  11 . The auxiliary cross bar  50 , therefore, enables a user to perform a variety of exercises such as push ups, sliding push ups, and thrusts over a range of difficulty from easy to difficult, as the auxiliary cross bar  50  is positioned from a top pair of brackets  22  on the base posts  20 , down to lower pairs of brackets  22 , and to the floor ( FIGS. 5 &amp; 6 ). 
       FIGS. 1-3  show a pair of vertical tower posts  41  each telescopically extending upwardly from a collar  24  on one of the base posts. An upper cross bar  40  is supported by the pair of vertical tower posts  41  with the upper cross bar  40  having a series of smooth gripping portions  48  for a user to grasp for pull ups and a series of notches  43  to receive at least one resistance band  60  for a user to perform a variety of pull down exercises. The vertical tower posts  41  are adjustable in height and adjust the height of the upper cross bar  40  to accommodate users of different heights and different exercises being performed using the upper cross bar. 
     In  FIGS. 1-4  and  7 , a pair of base pads  31  rests on a floor surface and are each removably connected to one of the base posts  20  by removable pin connections with a series of pad pins  15  in the base pad assembly  30  inserted into holes  16  in the base front leg  32 . The base pads  31  comprise resilient support surfaces to support a user performing exercises, and as shown in  FIGS. 7-10 , the base front legs  32  have at least one opening in each of the legs  32  to receive a pin  11  for attaching at least one resistance or tension band  60  thereto for performing a variety of exercises using the base pads  31  in conjunction with other modular components or, alternately, using the pads  31  removed from the other modular components to perform a variety of upper body work and lower body work exercises. 
     In  FIGS. 1-13 , all of the modular components are removably interconnected by pins  11  through mating openings in the components so that the device  10  may be fully assembled for use or the modular components separated for use of the components by a number of different users simultaneously. The pin connections  11  allow the entire device  10  to be disassembled by hand without the use of tools and inserted into a carrier  80 , as in  FIG. 15 , for transportation, thereby providing a portable, multipurpose, and modular exercise device separable into multiple, different exercise components. Thus a number of different users can be working out simultaneously on different exercise components separated from the same device. 
     In  FIG. 1 , the modular portable exercise device  10  is shown with all of the components assembled for use.

     In  FIGS. 6 and 14 , the means for attaching the at least one resistance band to the vest  70  is shown comprising mating hook and loop fasteners between hook and loop fastener strips  74  on a back surface  72  of the vest  70  and a mating hook and look fastener sleeve  64  on the resistance band  60  which is stretched between two ends of the auxiliary cross bar  50  with each handle  62  of the resistance band hooked over one end of the auxiliary cross bar  50  and over the back surface of the vest  70  of the user with mating hook and loop fasteners therebetween. 
     In  FIG. 15 , he storage and carry bag  80  for the modular portable exercise device  10  is used to carry all of the separated parts shown in  FIG. 2 . The bag  80  has straps  81  that allow for easy carrying. 
     In  FIGS. 1-3 , the upper cross bar  40  is shown comprising a pair of horizontal parallel spaced members  44  having notches  43  spaced apart along a top surface of each of the members  44 . A resistance band  60  is wrapped around a pair of the spaced members  44  and secured in the notches  43  to increase the stress of the exercise. 
     In use, the modular components of the present invention  10  can be separated out and used independently with tension straps (also called resistance bands)  60  attached to them for both upper body work and lower body work, as well as work as a regular work out bench, as in  FIG. 10 . While one user worked out on the base pads  30  doing various exercises, as in  FIGS. 7 ,  8 ,  9  and  10 , another user could work out on the auxiliary cross bar  50  as in  FIG. 6 , and another user could work out on the upright apparatus  10  using the upper cross bar, as in  FIG. 3 , minus the base pads  30 . 
     In the fully assembled upright configuration of  FIG. 1 , tension straps  60  can connect to the upper cross bar  40  above the shoulders and pulled down to simulate the exercise for the arms performed when doing pull ups. Pull ups can also be performed on a smooth hand receiving part  48 . 
     The portable modular exercise apparatus  10  is comprised of a plurality of components enabling numerous types of exercises by multiple users. The modular exercise apparatus  10  comprises two upright support towers  41  a base  20  under each support tower, an overhead crossbeam  40  and a supplemental sliding push up cross bar  50 , a plurality of resistance bands  60  which attach to the various components of the apparatus for the purpose of resistance training, and a carrying bag  80  to contain and transport all of the components. 
     The device  10  is a multi-function, multi-user exercise device which is separable into different components for different exercises so that a number of people can exercise at the same time by taking different components and performing different exercises with the components. The device when assembled stands higher than a person with the two tall towers  41 , the base  20 , and base pads  31  resting on the ground and several support brackets  25  and  35  resting against a wall. All of the components attach adjustably together using pins  11  with finger pull rings  13  inserted in different holes  12  to adjust the height or width of the different components. No tools are required. The exercise device allows for a complete range of users from beginners to advance fitness users by adjusting the different components. 
     The tower components  20  and  41  telescope up or down to adjust for different individuals of different heights. The upper cross bar  40  is supported by two telescoping towers to adjust the height of the upper cross bar  40 . In the fully assembled upright configuration of  FIG. 3 , tension straps  60  (also called resistance bands) can connect to the upper cross bar  40  above the shoulders to be pulled down to simulate the pull up exercise for the arms. The straps may be attached near the outer ends of the upper cross bar for doing resistance pec (pectoral muscle) pull downs, as in  FIG. 3 . And the tension of the straps  60  can be increased by winding them around the upper cross bar. Also the upper cross bar  40  may be adjusted in height, by altering the height of the towers  41  which telescope up, to allow different users of different heights to reach up to the upper cross bar and perform actual pull ups holding onto the smooth hand grip  48  portion of the cross bar  40 . 
     The base bars or stand  20 , which can be separated from the two towers, have notches or support brackets  22  to receive an auxiliary cross bar  50  (advance bar) for performing push ups or sliding push ups with the auxiliary cross bar  50  mounted in notches  22  at different heights so that at the highest point, a beginner can do push ups leaning against the wall at a slight angle from the vertical or do other exercises, such as leg thrusts at various angles depending on the height of the auxiliary cross bar. The handles  54  slide in the auxiliary cross bar and can slide freely for sliding push ups or be secured at any desired distance apart for still push ups. The auxiliary cross bar  50  can be separated from the combined device  10  and used independently on the floor for horizontal push ups, either regular push ups at different arm widths or sliding push ups. For advanced fitness users, a vest  70  with hook and loop fastener strips  74  (shown horizontally, but preferably should be attached vertically on the back of the vest) receives a tension or resistance strap  60  with a mating hook and loop fastener covering  64  connecting the strap to the back of the vest  70  and further connecting to the auxiliary cross bar  50  to create additional tension resistance on the user performing pushups on the bar shown in use with the bar. 
     The base pads  31  can be separated out and used independently with tension or resistance straps  60  attached to them to include upper body work and lower body work, and work as a regular work out bench as in  FIG. 10 . 
     It is understood that the preceding description is given merely by way of illustration and not in limitation of the invention and that various modifications may be made thereto without departing from the spirit of the invention as claimed.
