     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention deals with the field of weight lifting apparatus and in particular weight lifting apparatus designed for use in exercises making use of free weights. More particularly this apparatus is designed for use with exercises which bend the knees repeatedly. These are often referred to as deep knee bends and the user can increase the intensity of the exercise by increasing the amount of weight. This has the effect of increasing the stress on the user&#39;s shoulders which is necessary in order to intensity the exercise during such deep knee bends but which has the undesirable effect of creating excessive pressure on the back of a user. For this reason the present invention devises a means for further distributing that downward force on the user during such exercises and similar ones.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention provides a unique configuration for a weight lifting bar apparatus and is provided primarily in two embodiments. The first embodiment is the safety squat bar  10  shown in  FIGS. 1 and 2 . That bar is designed for holding free weights  14  at the outer extremities thereof and includes a central bar section  16 . Central bar section  16  includes a supporting bar section  22  in the central location thereof including a first end  18  and a second end  20 . The central bar section  16  extends approximately horizontally and defines a central bar axis  24 . 
     The safety squat bar  10  includes a first displacing bar section  26  which extends outwardly from the central bar section  16  along a first displacing axis  28  defined thereby. Similarly a second displacing bar section  30  extends outwardly from the second end  20  of central bar  16  along a second displacing axis  32 . Preferably the first displacing bar section  26  and the second displacing bar section  30  will be oriented at approximately 90 degrees relative to the central bar section  16 . As such, the first displacing axis  28  and the second displacing axis  32  will be oriented approximately perpendicularly with respect to the central bar axis  24 . 
     A first weight bar section  34  will be secured to the first displacing bar section  26  and extend outwardly therefrom for receiving free weights  14  secured thereonto. The first weight bar section  34  will preferably define a first weight bar axis  36  which preferably will form an acute angle of less than ten degrees relative to the central bar axis  24 . This angle is shown as angle  56 . 
     Similarly a second weight bar section  38  can extend outwardly from the second displacing bar section  30  in order to facilitate retaining of free weights  14  thereupon. This second weight bar section  38  will preferably define a second weight bar axis  40 . Preferably second weight bar section  38  and the second weight bar axis  40  thereof will be oriented at an acute angle relative to the central bar section  16  which is preferably less than ten degrees and it is also defined as angle  56 . 
     As an alternative configuration which is preferred, the safety squat bar  10  can include a yoke  42  including a first yoke member  44  extending forwardly from the central bar section  16 . This first yoke member  44  of yoke  42  preferably will include an inner first arcuate yoke section  46  and an outer first arcuate yoke section  48 . The inner first arcuate yoke section  46  is preferably shaped concave facing downwardly to mate with and extend over the upper portion of the shoulder of user. On the other hand the outer first arcuate yoke section  48  is preferably convex facing in the downwardly direction and is designed to mate with the upper chest area of a user and mate in the concave area between the lower portion of the shoulder and the beginning of the pectoral muscle and chest. 
     In a similar manner a second yoke member  50  may extend outwardly from the central bar section  16  laterally displaced from the first yoke member  44 . This second yoke member preferably will include a second inner arcuate yoke section  52  which is preferably concave in a downwardly facing direction to facilitate mating thereof with the convex upper shoulder area of a user. The second yoke member  50  will also preferably include an outer second arcuate yoke section  54  which is preferably convex in a downwardly facing direction to mate with the generally concave shaped area of a user&#39;s body between the lower portion of the shoulder and the upper front chest area. The first yoke member  44  and the second yoke member  50  will be spaced apart from one another and define therebetween a head zone for receiving of the head of a user such that the two yoke members can extend down either side of the head along the upper shoulder area and in this manner more evenly distribute the weight exerted by the weight lifting bar upon the shoulders of the user. 
     The safety squat bar  10  may define a first central gripping zone  58  and a second central gripping zone  60  spaced apart from one another to facilitate gripping thereof for enhancing the exercising experience of movement of the safety squat bar  10 . 
     The monster jam bar  12  is defined best in  FIGS. 3–7  but has many similar characteristics to the safety squat bar  10 . The monster jam bar  12  can include a similar construction for the yoke  42  including the first yoke member  44  and the second yoke member  50 . It also can include padding  78  extending over each of these yokes. This padding  78  can be used with the yoke  42  of the safety squat bar  10  or of the monster jam bar  12 . 
     Thus the configuration of the first yoke member  44  and the second yoke member  50  of the yoke  42  is the same when included with the safety squat bar  10  as well as the monster jam bar  12 . Also each bar can include a similar angular relationship between the first weight bar axis  36  of the first weight bar section  34  and the central bar section  16 . Similarly these two bars both utilize the same relative angular relationship between the second weight bar section  38  and, in particular, the second weight bar axis  40  thereof relative to the central bar section  16 . The angle is defined as angle  56  which is preferably defined to be less than ten degrees. 
     The monster jam bar  12  includes additional structural designs and can define a first lateral bracket  62  extending outwardly from the first displacing bar section  26 . This first lateral bracket preferably defines a first mounting aperture means  64  therewithin. The first mounting aperture  64  is utilized for the purposes of facilitating mounting of the weight lifting bar apparatus relative to weight lifting bar holding racks or other similar environmental structure. 
     The first lateral bracket  62  preferably includes a first transverse bracket  66  extending approximately horizontally outwardly from the first displacing bar section  26  adjacent the first end  18  of the central bar section  16 . A first vertical bracket  68  can extend upwardly from the first weight bar section  34  to the first transverse bracket  66 . In this manner the first transverse bracket  66  and the first vertical bracket  68  will define two boundaries for the first mounting aperture  64 . The other two boundaries which will define this aperture are provided by the first displacing bar section  26  and the first weight bar section  34 . 
     In a similar manner a second lateral bracket  70  may be positioned adjacent to the second displacing bar section  30 . Preferably second lateral bracket  70  includes a second transverse bracket member  74  extending approximately horizontally from the second displacing bar section  30  at a point thereof adjacent to the second end  20  of the central bar section  16 . Also a second vertical bracket  76  can interconnect the second displacing bar section  30  with the second transverse bracket  74  and in this manner enclose and completely define the second mounting aperture  72 . 
     Weight lifters can vary greatly in size, shape and capability. For this reason the present invention provides four different grasping locations for grasping the monster jam bar  12  to facilitate exercising therewith. The primary gripping means will be the first primary gripping area  80  which is preferably defined on the first displacing bar section  26  immediately adjacent to the first weight bar section  34  thereadjacent. Similarly a second primary gripping zone  82  can be defined on the second displacing bar section  30  in the area thereof immediately adjacent to the second weight bar section  38 . 
     Another alternative gripping location is the lower gripping members defined as the first lower gripping member  84  and the second lower gripping member  86 . To facilitate mounting thereof a first strut  88  may be fixedly secured to the first weight bar section  34  in the area thereof adjacent to the first displacing bar section  26 . This strut will provide a location for attachment of the first lower gripping means  84  thereto. Preferably first lower gripping means  84  will extend outwardly therefrom in an approximately horizontal direction. In the preferred embodiment of the present invention the first lower gripping member  84  is detachable from the first strut  88  as shown best in the configuration of  FIG. 6 .  FIG. 6  shows the detachable nature of the first lower gripping means  84 . With this configuration a bolt  100  extends through an aperture defined in the first strut  88  and defined in the first primary gripping member  80  and is attachable to a nut  102  for detachably securing the first primary gripping member  80  in place. 
     A second lower gripping member  86  is also preferably included in the apparatus of the present invention. A second strut  90  is fixedly secured to the second weight bar section  38  in the area thereof adjacent to the second displacing bar section  30 . Second strut  90  provides an attachment location for the second lower gripping member  86 . Preferably the second lower gripping member  86  will extend approximately horizontally outwardly therefrom. In the preferred configuration, also as shown in the same construction shown in  FIG. 6 , the second lower gripping member  86  can be detachably securable with respect to the second strut  90 . Removal of the first lower gripping members  84  and the second lower gripping members  86  with respect to the respective struts provides a unique capability in the present invention since in some situations additional clearance is required for mounting or exercising with the monster jam bar. 
     Another alternative means of gripping the monster jam bar  12  is provided by the first outer gripping member  92 . First outer gripping member  92  is attached to the first displacing bar section  26  and extends upwardly and rearwardly therefrom. The first outer gripping zone  92  preferably is secured to the first weight bar section  34  within the area thereof defined as the first mounting aperture  64 . 
     In a similar manner a second outer gripping member  94  can be affixed to the second weight bar section  38  at a position thereof inboard from the second vertical bracket member  76  such that it extends upwardly and rearwardly therefrom. With this configuration the second outer gripping member  94  will be positioned within the second mounting aperture  72  and will extend rearwardly therefrom. 
     A further embodiment of the gripping means provided by the capability of the present invention is shown with the first outermost gripping zone  96 . First outermost gripping zone  96  is defined on the first vertical bracket member  68 . Similarly the second outermost gripping means  98  is defined on the second vertical bracket member  76 . Thus the present invention provides the capability for a user holding the monster jam bar  12  with horizontal or vertically oriented gripping locations or gripping locations located partially horizontally and partially vertically such as the angular securement provided by the first and second primary gripping means  80  and  82 . Also the distance of the gripping width can be varied significantly from the widest grip which is provided by the first and second outermost gripping members  96  and  98  to the innermost positions provided by the first and second primary gripping means  80  and  82  or the first and second lower gripping means  84  and  86 . 
     The present invention provides a unique configuration for a weight lifting bar which is particularly usable for deep knee bend exercises performed with large amounts of weight positioned on the first weight bar section  34  and the second weight bar section  38 . Such exercises normally require a significant amount of weight on the bar and can be excessively uncomfortable on the shoulders of a user. The present invention provides a way for overcoming this difficulty by equally distributing the weight over the shoulders of a user due to the unique yoke of the present invention as well as allowing the weights to be retained upon the weight receiving bars without the necessity of including collars due to the upwardly angled inclination thereof. Also the present invention provides multiple means for grasping of the safety squat bar  10  and the monster jam bar  12  and in this manner provides a more universally usable exercising device for use with free weights. 
     While particular embodiments of this invention have been shown in the drawings and described above, it will be apparent, that many changes may be made in the form, arrangement and positioning of the various elements of the combination. In consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention.
A weight lifting bar apparatus usable with free weights which includes two weight bar sections which are angularly oriented upwardly with respect to the main central bar section to facilitate retaining of weights thereon during exercising. The apparatus may also include a yoke means comprising two individual yoke members having an inner concave downwardly facing section and an outer convex downwardly facing section to facilitate contour to against the shoulders and chest area of a user. The design may also include lateral brackets mounted on the weight lifting bar apparatus and defining mounting apertures thereadjacent to facilitate storage upon a weight rack. As many as four different gripping locations can be defined at various positions on the different configurations of the bar apparatus herewithin.
