Description:
BACKGROUND OF THE INVENTION 
       [0001]    This non-provisional patent application is based on provisional patent application Ser. No. 62/213,230 filed Sep. 2, 2015. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates to an exercise apparatus and, more particularly, to a apparatus having one or more vertical walls or frame members with attachment points thereon to facilitate selective attachment of various resistance devices thereto in order to perform a variety of exercises of different muscle groups. 
       DISCUSSION OF THE RELATED ART 
       [0003]    The exercise and development of different muscle groups and subgroups of the human body requires an extensive variety of movement of the arms, legs, back and shoulders through various ranges of movement at different angles while moving against the force of resistance. Conventionally, exercises of the various muscle groups have been performed with the use of free weights, such as on a barbell or dumbbells. Over time, more advanced equipment has been developed for exercising targeted muscle groups by moving a bar, handgrip or other device through a range of movement. In many cases, these various types of equipment will use a cable that is directed through a series of pulleys and attached to a stack of weights. The user can select the amount of weight by using an adjustably positionable pin within the stack of weights so that only the selected amount of weight is lifted by the cable as the user performs the exercise movement. The angle of movement is usually restricted to a certain range and limited number of exercises for specific targeted muscle groups. Accordingly, in order to exercise all of the various muscle groups and subgroups of the human body, it is necessary to have a large number of different exercise machines, with each exercise machine limited to a specific muscle group and/or subgroup. For convenience, various home gyms have been developed that allow for a variety of exercise movements to be performed, usually by using different stations on the home gym and interchanging various equipment, such as handles, bars, leg engaging devices, etc. However, home gyms have limitations and are not able to provide for a full range of exercises to properly strengthen, tone and build all the different muscle groups and subgroups of the human body. 
         [0004]    Accordingly, there remains a need for a single apparatus that allows for exercise of all the different muscle groups and subgroups of the human body, for purposes of strength training, muscle toning and muscle building (i.e., bodybuilding). Moreover, there remains a need for a single apparatus that allows for attachment of various resistance devices at all different angles through virtually a 360 Degree dimensional point of attachment so that a user can perform all different types of exercises to properly exercise and develop all the different muscle groups and subgroups of the human body. Furthermore, there remains a need for a single apparatus that allows for use of various resistance devices that selectively attach to a large number of attachment points at different angles throughout virtually a 360 Degree dimensional point of attachment while eliminating the need for heavy weights, such as weight plates. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention is directed to an exercise apparatus, and more particularly a gym cage that is designed to be used as a supporting structure for a variety of other exercise devices. 
         [0006]    The apparatus consists of a metal skeletal frame having one or more walls and can be square, rectangular, circular, oval, or various other configurations. A rectangular shape with four sides and three walls is illustrated in the attached drawings. The gym cage can be constructed in various dimensions as long as it is sufficiently tall, wide, and deep to allow for a tall standing person to complete a variety of exercises within its dimensions. The embodiments illustrated in the attached drawings are approximately 8 foot tall, 7 foot wide, and 5 feet deep. 
         [0007]    The gym cage apparatus does not utilize weight plates, rather it relies upon a variety of strategically placed attachment points that enable cabled resistance devices to be attached. By attaching a hand held resistance device (see  FIGS. 38-40 ), a stretch band resistance device (not shown), or any other similar resistance device to any of the vertical bars, and/or horizontal bars and/or adjustable height ceiling, and/or metal floor of the gym cage, the user has virtually a 360 degree dimensional point of resistance to perform a wide variety of exercises. 
         [0008]    The key function of the gym cage apparatus is to provide the strategically placed attachment points for easily and quickly attaching and disconnecting the resistance devices throughout a workout routine. Presently, three types of attachment points are contemplated and include inset (i.e., recessed) attachment points, fixed hook attachment points and adjustably positionable hook attachment points. Other attachment mechanisms and designs are contemplated within the scope of the invention as well. Resistance devices that are fully contemplated for use with the present invention include, but are not limited to, adjustable resistance devices, such as disclosed in U.S. Pat. No. 8,905,904, which can include adjustable resistance handgrip devices, and bar devices, as well as adjustable resistance inline devices. Elastomeric resistance bands and cords are also contemplated for use with the present invention.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0053]    The gym cage of the present invention is shown and generally indicated as  10  throughout the drawings. The gym cage  10  includes at least one vertical wall structure and, in a preferred embodiment, includes a rear wall structure  12  and opposite side wall structures  14 ,  16  (i.e., left and right walls) extending upwardly from a floor  18  to a top  19  of the cage  10 . 
         [0054]    As seen in  FIGS. 1 and 2 , the vertical side wall structures  14 ,  16  and rear wall structure  12  of the gym cage  10  may be formed by an arrangement of parallel vertically extending bars or frame members  20  that are spaced apart to allow visibility through the entire gym cage. The rear wall structure  12  and side wall structures  14 ,  16  may further include at least one horizontal bar or frame member  22 , as seen in  FIG. 1 . The top  19  of the cage  10  may be formed by a similar arrangement of spaced and parallel bars or frame members or, alternatively, the top  19  may be a solid structure, similar to the floor  18  of the cage  10  which is shown in  FIG. 16 . The rear wall structure  12 , opposite side wall structures  14 ,  16 , top  19  and floor  18  provide for an arrangement of attachment points  24  for selective, interchangeable and removable attachment of resistance devices, such as the adjustable resistance handgrip device  30  shown in  FIGS. 6 and 6A , as well as the inline adjustable resistance device  40  shown in  FIG. 7 . Attachment of these adjustable resistance devices to the various attachment points  24  on the vertical wall structures, top and floor of the gym cage  10  allow for virtually 360 degrees of attachment points to perform a wide variety of exercises for exercising, developing, toning and building different muscle groups and subgroups of the human body. The gym cage  10  may further include an adjustable height ceiling  50 , as shown in  FIGS. 1, 2 and 12-15  to allow users of different heights to easily reach the attachment points  24  on the adjustable height ceiling  50  in order to attach the various adjustable resistance exercise devices (e.g.,  30  and  40 ). 
         [0055]    The attachment points  24  on the vertical wall structures (i.e., the back wall and opposite side walls) as well as the ceiling/top and floor of the gym cage  10  may be either fixed or adjustable in position. Moreover, the attachment points  24  may be recessed or inset, as seen in  FIGS. 3-6  or exposed on a surface of the wall structures  12 ,  14  and  16 , ceiling/top  19  and floor  18  of the cage  10 , in the form of hook attachment points  70 , as seen in  FIGS. 8 and 9 . Moreover, the attachment points may be adjustably positionable, such as adjustably positionable hook attachment points  80  shown in  FIGS. 10 and 11 . 
         [0056]    The inset attachment points  60  generally consist of a pocket area  62  within the walls or frame members  20 ,  22  of the gym cage  10 , such as within the frame members  20 ,  22  of the rear wall structure  12  and opposite side wall structures  14 ,  16 , as well as within the ceiling/top  19  of the gym cage  10  and the floor  18  of the gym cage. The inset attachment points  60  further include a transverse attachment bar  64  that extends within the pocket  62 , connecting to the frame member or other structure on opposite sides of the pocket  62  so that the transverse attachment bar  64  is inset from the surface of the walls, ceiling and floor of the gym cage. As seen in  FIGS. 3-6A  the inset attachment points  60  are particularly suited for attachment of a quick connect coupler  32  on the adjustable resistance handgrip device  30 . In particular, the quick connect coupler  32  includes a generally C-shaped claw  34  fitted to a coupler stem  36  that is attached to a cable  39  extending from the spool  31  of the adjustable resistance handgrip device  30 . The open mouth of the generally C-shaped claw  34  of the quick connect coupler is normally closed by a spring loaded latch  35 , as seen in  FIG. 4 . The quick connect coupler  32  is easily attached to the attachment point  24  (either the inset attachment point  60  or the hook attachment point  70  or adjustable hook attachment point  80 ) by jamming the quick connect coupler  32  into the bar of the inset attachment point or hook and causing the bar of the attachment point  24  to move the spring loaded latch  35  open, until the bar passes within the enclosure of the claw  34  and clears the latch  35 , whereupon the spring loaded latch  35  is urged back to the closed position, as seen in  FIG. 4 . To remove the quick connect coupler  32  from the attachment point, a one finger quick release mechanism  38  is operated to urge the latch  35  open so that the bar (i.e., inset or hook) of the attachment point  24  can be moved out through the open mouth of the claw  34  of the quick connect coupler, as illustrated in  FIG. 5 . Easy one handed attachment of the quick connect coupler  32  to the attachment point  24  is achieved by the structure of the quick connect coupler  32  and frame  33  of the handgrip device  30 . Specifically, referring to  FIG. 6A , the frame  33  of the handgrip device includes a cradle  37  that is specifically sized and configured for congruent receipt of the coupler stem  36  therein, holding the quick connect coupler  32  secure relative to the handgrip resistance device frame and grip handle, so that the user, with one hand grasping the handle  33 a of the handgrip device, can jam the quick connect coupler  32  against the attachment point  24 , with the bar of the attachment point  24  urging the spring loaded latch  35  open until the bar of the attachment point is secure within the grasp of the claw  34  of the quick connect coupler  32 , as shown in  FIG. 4 . 
         [0057]    Referring to  FIG. 7 , the inline adjustable resistance device  40  includes two separate attachment hooks  42 ,  44  for attachment to an item of equipment, such as a barbell  110 , arm attachment device  120 ,  130  or leg attachment device  140 , as well as one of the many attachment points  24  on the gym cage. One of the hooks  42  of the inline adjustable resistance device  40  is fitted to the end of a fixed cable  43 , while the other hook  44  is fitted to a cable  45  that extends from the resistance spool  31  of the device. 
         [0058]    The operation of the adjustable resistance handgrip device  30  and the inline adjustable resistance device  40  is consistent with the disclosure in U.S. Pat. No. 8,905,904. In general, the adjustable resistance is achieved by opposing piston heads  47 ,  48 , as seen in  FIG. 7 , wherein resistance is created by either compression of air between the piston heads, a spring between the piston heads or a magnetic force created by opposing force magnets on each of the piston heads. Adjusting the distance between the piston heads  47 ,  48 , by screw rotation of either or both pistons, with the use of an adjustment knob  49 , allows for adjusting the resistance of force to rotate the spool  31 . This in turn translates to a force of resistance of pulling the cable from the spool, as described in more detail in U.S. Pat. No. 8,905,904. In the instance magnets are used, an electromagnet may be positioned on the left side of the chamber within the spool and a standard magnet may be placed on the head of the piston on the right side of the chamber. The magnets create a repulsive field between them, and the strength of the repulsive field can be controlled by the electrical current flowing to the electromagnet, thereby controlling the force of resistance of pulling the cable from the spool. 
         [0059]    Referring to  FIGS. 10 and 11 , the adjustable positionable hook attachment points  80  include a hook  82  fitted to a central hub  83  that is fastened to a guide block  84  by a bolt  85  that passes through a vertical slot  25  in a frame member  20  of the gym cage  10 . The guide block  84  is specifically sized and configured for sliding movement within a hollow interior channel  23  of the frame member  20  of the gym cage. The adjustable positionable hook attachment point  80  further includes a locking pin  86  arrangement including a second bolt  87  that extends through the vertical slot  25  of the frame member and into the guide block. The portion of the bolt  87  extending exteriorly of the frame member, including the bolt head, is surrounded by a movable knob  88 . A spring  89  is fitted between the bolt head and the inner end of the knob  88  so that the knob can be pulled outwardly against the force of the spring  89  away from the frame member  20 . A collar  88   a  of the knob  88  is specifically sized and configured for selective receipt within any one of an arrangement of vertically spaced holes  27  formed along the open slot  25  of the frame member  20 . To adjust the hook attachment point  80  up or down, the knob  88  is pulled outwardly against the force of the spring  89  and released from the hole  88  in the frame member  20  allowing the hook  82 , guide block  84  and bolts  85 ,  87  to slide up or down until the knob  88  is aligned with one of the spaced holes  27  along the open slot  25  at the desired height or position of the hook attachment point. When reaching the desired position, the knob  88  is released and the knob collar  88   a  is allowed to snap into place within the aligned hole  27  on the open slot  25  of the frame member  20  thereby securing the hook attachment point  80  at the desired adjusted position. 
         [0060]    Referring to  FIGS. 12-15 , an adjustable height dropdown ceiling  50  is shown. The dropdown ceiling  50  is provided with an arrangement of attachment points  24 , either or both the inset attachment points  60  and/or hook attachment points  70 , and is able to be adjusted in height relative to the floor  18 , top  19  and vertical wall structure of the gym cage  10 . The dropdown ceiling  50  secured in place by opposing locking pin members  52  on opposite ends of the dropdown ceiling which are received within any select set of a spaced arrangement of locking apertures or holes  54  on the same horizontal plane in the wall structure of the gym cage, as seen in  FIG. 12 . To adjust the height of the dropdown ceiling  50 , the user pulls a cord  55  to operate a pulley and spring mechanism  57  (see  FIG. 15 ) that urges the locking pins  52  inwardly towards the interior of the dropdown ceiling, and out of the locking holes  54  in the wall frame members  20  of the gym cage so that the dropdown ceiling  50  is free to move up or down while the cord  55  remains pulled and the locking pins  52  remain in the retracted position. To assist with raising or lowering the dropdown ceiling, a vertical bar  56  extends down from the dropdown ceiling  50  and can be grasped by the user. This vertical bar  56  assists users of different heights who may not otherwise be able to reach the ceiling  50  and is otherwise necessary to pull the ceiling  50  down to an adjusted lowered position. When the dropdown ceiling  50  is at the desired height, the cord  55  is released, causing the locking pins  52  to extend out from the sides of the ceiling  50  and into the aligned locking holes  54  in the frame structures  20  of the gym cage. The weight of the dropdown ceiling  50  is supported by a spring roller  58  or coil and cable  59 , as seen in  FIG. 14 . Specifically, a spring loaded coil, pulley or roller  58  is mounted within the top of the gym cage frame structure and a cable  59  extends down and connects to the dropdown ceiling  50 . This allows the user to raise or lower the dropdown ceiling  50  with minimal effort, while preventing the ceiling from falling down onto the user. A minimum amount of force is necessary to pull the ceiling  50  down, by grasping the vertical bar  56 . Without pulling down on the bar  56 , the ceiling  50  will remain either stationary or begin to rise upwardly as the spring loaded coil/pulley mechanism  58  supports the weight of the ceiling  50  and may in fact lift the ceiling  50  back to the fully raised position when the locking pins  52  are disengaged. 
         [0061]      FIG. 15  illustrates the general schematic of an arrangement of the pulley and spring locking pin release mechanism  57  wherein the cord  55  extends about an arrangement of pulleys and connects to the arm members of the two locking pin structures which are urged against springs when pulling down on the cord, thereby allowing the locking pins  52  to retract into the ceiling. Upon release of the cord  55 , the springs urge the locking pins  52  outwardly so that they can be received within the selected horizontally aligned set of locking holes on the gym cage frame members  20 .
