for the purpose of illustrating some embodiments of the invention , there is shown in the accompanying drawings several exemplary embodiments of the present invention . it is to be understood that the invention is not intended to be limited to the precise arrangements and instrumentalities shown . the example embodiments will become more fully understood from the detailed description given herein below and the accompanying drawings , wherein like elements are represented by like reference numerals , which are given by way of illustration only and thus the present invention is not limited by the examples . turning now to fig1 , an exercise device 100 includes a base crossbar 101 which is adjustable lengthwise . one method to adjust the crossbar is shown in fig1 in which the crossbar comprises two sections , one section being smaller than the other section and thereby fitting slideably into the other section . the two sections are held in place by a securing mechanism , such as , for example , a locking pin , as depicted by 102 in fig1 . adjustments are made lengthwise , and locking in place is maintained using apertures 103 incrementally placed along the axis of the thinner section that slides into and out of the outer section . an aperture is provided in the thicker section of the crossbar which can align with the apertures of the thinner section to allow the locking mechanism to secure the two sections . the outer ends of the base crossbar are each securely attached to a bracket 104 . also attached to the brackets 104 are floor bars 105 . the floor bars are pivotally attached to the brackets using a pivot . in use , the four floor bar sections are securely attached to the brackets in a fixed position . when not in use the floor bars are unsecured and folded up vertically while their ends are still attached to the brackets . also securely attached to the brackets is a pair of vertical bars 106 which contain apertures 107 incrementally placed along the axis of the bars for adjustments . slideably attached to the vertical bars are one or more holding devices , such as , for example , hard grips 108 shown in the figure . the hand grips are comprised of a collar that fits around the vertical bars and slides up and down the axis of the bars . the collar contains niches on opposite sides of the collar to allow a locking mechanism 109 to secure the collar and hand grips to the vertical bars , the niches in the collar aligning with the apertures in the bars . other device ( s ), such as a slideably attached crossbar could also be used in some embodiments of the current invention . the height of the hand grips is achieved by removing the locking mechanism , sliding the collar of the hand grip up or down the length of the vertical bar until a desired incremental height is reached , and then replacing the locking mechanism . an exploded view of a rotatable hand grip 108 is shown in fig2 . securely attached to ( e . g ., integrally formed with ) the collar 111 is a base 112 and in the collar are niches 113 for securing the hand grips on the vertical bars . for increased strength a brace 114 is attached under the base and attached to the collar . the rotating portion of the hand grip is a rotatable base 115 with a gripping bar 116 securely attached horizontally to two vertical brackets 117 which are in turn attached securely to the rotatable base . the rotatable portion of the hand grip 115 is held in place on ( albeit capable of rotation on ) the base 111 using a pivot pin 118 placed through a pivot hole 119 in the rotating base and through a pivot hole 120 in the base 111 . the pin is held in place by a washer 121 and a nut 122 . the pivot pin 118 is threaded only on the end to receive the nut . this configuration allows the rotatable portion of the grip 118 to securely rotate around the pivot pin 118 on top of the base 111 without sliding off the base . attached to the rotatable base 115 , using an attaching device 124 such as a screw , is a securing mechanism 123 which prevents rotation of the rotatable base 115 relative to the base 112 when the device is in use . the mechanism has a nipple device 125 on the bottom of the securing mechanism which locks into a prefabricated arrangement of niches 126 in the base 112 . the securing mechanism 123 is fitted through a slot 127 in the rotatable base 115 . during use the securing mechanism 123 is lifted through the slot 127 in the rotatable base to allow free movement of the rotatable portion of the hand grip to rotate to a desired position and then released to engage the nipple device into the niche and thus a locked position . the gripping portion of the hand - grip , the gripping bar 116 , may be covered with pliable material for gripping comfort , such as rubber or rubbery covering or a tape which is pliable or other pliable polymer coating . the collar 111 fits snuggly over the vertical beams so that the collar can easily slide up and down the beam for adjustability but is tight enough to allow for very little or no movement of the collar during use in exercising once the collar and hence the hand grip is secured in place . a view of the hand grip 108 in use is shown in fig3 . as can be seen the hand grip collar 111 is slideably attached to the vertical bar 106 using a locking mechanism 109 , in this case a locking pin , which is positioned through apertures 107 in the vertical bar and also aligned with the niches 113 of the hand grip collar . in some embodiments of the present invention , each collar 111 may have four niches positioned respectively at 90 , 180 , 270 , and 360 degrees around the circumference of each end of the collar to allow for various corresponding positions of the hand grips 108 during use . in fig4 a first crossbeam 130 is slideably attached to the vertical bars . the first crossbeam is securely attached to collars 131 that fit around the vertical bars 106 and slide up and down the axes of the vertical bars . each collar contains niches 113 on opposite sides of the collar to allow a locking mechanism 109 to secure the collar and first crossbeam to the vertical bars , the niches in the collar aligning with apertures 107 in the vertical bars . the first crossbeam is covered with padding 132 . attached to the end of one pair of half beams of the floor bars is a set of brackets 133 to which is attached a second crossbeam 134 also covered with padding 132 . the second crossbeam and brackets are arranged so that the first and second crossbeams are parallel . in use , the first crossbeam slide up and down the vertical bars until a desired position is reaches and the locking mechanism is engaged . in fig5 a bracket 104 is shown to which the base crossbeam 101 , the vertical bar 106 and the half beams of the floor bars 105 are attached . the position of the floor bars as shown as they would be deployed during use , that is , they are extended outward and securely locked in place using a locking mechanism 140 as described herein to provide for stability . the half beams of the floor bars are also pivotally attached to the bracket using a secured pivot pin 141 . the configuration shown in fig5 may be particularly suited for , for example , core strengthening exercises including abdominal crunches and lower - back extensions . in fig6 a bracket 104 is shown wherein the half beams of the floor bars 105 are disengaged from their locked stability position and folded up by pivoting around pivot pins 141 to allow for storage . when folded the exercise apparatus is essentially flat and easily storable . as shown in fig1 , 4 , 5 , and 6 , also attached to each bracket 104 may be a wheel or other roller mechanism 142 for allowing ease of transport of the device when floor bars 105 are in the folded position . in a further embodiment the hand grips may be turned upside down ( relative to their positioning shown in fig1 and 3 ) and slideably attached to the vertical bars . as shown in fig1 , 2 , and 3 , there are niches 113 on both ends of the collar to accommodate two positions of the hand grip , when the hand grips are in use . in one position the hand grips are on top and push - ups and dips can be performed . in the other , reverse position , pull - ups can be performed . in a further embodiment the handgrips may be removed from the exercise device and adjusted so that weights may be mounted to the hand grips to allow the hand grip to be used in kettle bell style exercises such as cleans , jerks , rows , floor presses , squats , swings , windmills and a whole host of other kettle bell style exercises . fig7 shows an exploded view of a hand grip which has been removed from the exercise device and to which five weights have been mounted . the hand grip contains the collar and the base 146 . the rotating portion of the hand grip is a rotatable base 115 with a gripping bar 144 . the gripping bar 144 is securely attached horizontally to two vertical brackets of the rotatable base 115 using fasteners 143 . the rotatable portion of the hand grip 115 is held in place on ( albeit capable of rotation on ) the base 146 using a pivot pin 118 placed through a pivot hole in the rotating base 149 and a pivot hole in the base 146 . a weight mounting adapter 147 is attached to the underside of the base 146 and is held in place by a washer 121 a nut 122 and pivot pin 118 . the pivot pin 118 is threaded only on the end to securely receive the nut 122 . attached to the rotatable base 115 , using an attaching device 124 such as a screw , is a securing mechanism 123 which prevents rotation of the rotatable base 115 relative to the base 146 when the device is in use . the gripping portion of the hand - grip , the gripping bar 144 , may be covered with pliable material 145 for gripping comfort , such as rubber or rubbery covering or a tape which is pliable or other pliable polymer coating . weights 148 , further described below and in fig9 , are securely mounted to the weight mounting adapter 147 and to themselves . fig8 shows the weight mounting adapter 147 . the outer edge of the adapter is threaded in a male configuration 153 such that a weight which has a matching female thread , as described below in fig1 , will mount readily to the adapter . the adaptor also contains a hole in the middle through which the pivot pin 118 in fig7 fits through so that a washer and nut can be placed to securely attach the adapter to the base . fig9 shows an exemplar embodiment of a weight that is suitable for the current invention . fig9 a shows an edge view of the weight 148 with a threaded male protrusion 150 . fig9 b shows a cut away side view of the weight 148 showing both the threaded male protrusion 150 and a female recession 151 in the weight designed to receive the male protrusion of either the weight mounting adapter 147 in fig7 or another weight 148 . the depth of female recession ranges from 10 - 75 percent of the thickness of the plate . the exact depth depends on the amount of weight of the weight , the material used to make the weight and the size of the male protrusion . the height of the male protrusion is slightly less than the depth of the female recession so that the end of the flat end of the male protrusion will not come into contact with the flat innermost portion of the female recession so that there will not be any additional resistance to removing the weight due to friction of the two flat surfaces . fig1 shows an oblique view of a hand grip with five weights 148 mounted to the hand grip 108 . also show is the gripping bar 116 . fig1 shows a cross sectional view of a hand grip with one weight 148 mounted to a weight mounting adapter 147 , the adapter being held in place by a pivot pin 118 . in practice the hand grip is slid off the vertical posts of the exercise device . the part that secured the pivot pin , either a nut , cross - screw , cotter pin or other securing device , is removed and the weight mounting adapter is placed on the end of the pivot pin that protrudes from the underside of the base . the pivot pin may be replaced with a different pivot pin that is longer , designed specifically to accept the weight mounting adapter . a weight is then mounted onto the adapter by a screwing motion . the threads are designed to accept each other . the threads of the mounting adapter and the weight may extend anywhere from half - way around to one or more complete rotation . the configuration of the threads is selected to provide security to hold the weights in place during use . a second weight may be added by screwing the male protrusion of the already mounted weight into the female recession of the weight to be added . this process is repeated as little or as much as is needed until a desire weight has been reached . in practice one or both of the handgrips may be adjusted with weights and used to exercise . thus the exercise device of the current invention provides a full range of exercises . the weights shown and described herein may be configured to be mounted to the hand grip and each other by means other than a threaded adapter and threaded weights . such means include a bar extending from the hand grip to which weights are attached by such means as cotter pins , screws , or other such attachments ; a threaded bar extending from the hand grips to which a threaded weight is attached ; weights designed with locking mechanisms such as plunger and socket arrangements and other means .
