Primary Examiner-Richard C. Pinkham Assistant Examiner-R. T. Stouffer Attorney-Zarley, McKee & Thomte s7] 1 ABSTRACT An exercise device including a pair of upright poles interconnected by top and bottom cross members, the bottom cross member being slidable on the poles and adapted to be biased upwardly by spring elements at opposite ends. A horizontally disposed weight may be detachably carried on the bottom cross member. U shaped members are pivotally and slidably connected to the poles to provide parallel handles when pivoted to an inwardly extending position and provide supports for a pivotal bed frame when the U-shaped members are pivoted outwardly. The bed frame is pivoted such that the center of gravity of the exerciser will be shifted back and forth across the pivotal axis by moving the hands from the sides towards the head.
, A canvas material supports the buttocks, back and head while a pair of cross elements engage the ankles and the feet. The cross elements are adjustable along the length of the body frame and with respect to each other. A pair of U-shaped hooks may be secured to the exercisers ankles and engage the top cross bar to suspend the exerciser in an inverted position or engage one of the cross elements on the body frame to hold the exerciser stationary on the body frame as he pivots from an upright position to an inverted position.
9 Claims, 17 Drawing Figures PATENTED DEC 2 6 1972 SHEET 1 BF 2 HORIZONTAL BAR EXERCISING DEVICE There are presently several exercising devices on the market however,-they each have limited capabilities for the exerciser. The exercise device of this invention is compact, sturdy and fulfills the need of a multi-purpose exercising unit.
The exercise unit capitalizes on what is called gravity guiding system involving the alternating of the bodys posture in respect to the fixed center of gravity. Examples of this are freely hanging by the hands, freely hanging by the feet, chinning with a spring assist, an inverted squat, an inverted setup, drawup with weights, parallel dip with assist, free hang by feet with weights, and an inverted extension. There are other basic exercises that use the natural force of gravity to help restore the muscle tone and improve healthful posture. These are exercises that most men and women, regardless of age, have possibilities of achieving.
The use of a body frame or slant bed involves the exerciser wearing boots having hooks thereon secured to cross elements on a pivotal body frame. The feet rest against a parallel cross element. The slant bed is operated byleaning against the bed which starts a slow.
motion to a horizontal position. With the slow movement of the arms up and over the head the inversion action begins. The bringing of the arms back to the sides returns the slant bed back to the normal upright starting position. The arm action will hold any position by stopping arm motion. It is the action of the arms only that controls the entire movement from start to finish. The boot hooks disclosed in this application are covered by applicants issued US. Pat. No. 3,380,447, Apr. 30, I968.
These and other features and advantages of this invention will become readily apparent to those skilled in the art upon reference to the following description when taken into consideration with the accompanying drawings, wherein:

The exercisedevice of thisinvention is referred to generally in FIG. 1 by the reference numeral 10 and includes a pair of uprights or poles l2 engaging the floor 14 at the bottom and the ceiling 16 at the top. The poles 12 are spaced apart sufficiently for a person 18 (FIG. 2) to perform exercises there between.
A vertically, slidable bottom cross bar unit 20 includes end sleeves 22 embracing the poles 12. A platform 24 is provided in the center on the cross-bar 26. Outwardly of the platform 24 are hand gripping stations 28 on the cross-bar element 26.'The sleeves 22 include outwardly extending elements 30 detachably engaged by vertically positioned elastic spring elements 32 vertically ,adjustably anchored to brackets 34 on the post 12 thereby normally biasing the cross-bar unit 20 upwardly. 1
A pair of U-shaped upwardly facing weight support brackets 36 extend perpendicular 'to the cross-bar unit 20 and are adapted to receive'a weight unit 38 including an elongated shaft 40 which extends parallel to the cross-bar unit 20. Weight elements 42 are selectably placed on the shaft 40 of the weight unit 38.
U-shaped handle member units 44 as seen in FIG. 11 are provided on each of the poles l2 and when positioned as seen in FIG. 1 provide parallel bars for the exerciser 18 as seen in FIGS. 5 and 6. The same units 44 facilitate use of an inclined bed or body frame unit 46 as shown in FIG. 13 and which will hereinafter be described in more detail.
The handle units 44 include a sleeve 48 slidable on the poles l2 and adapted to beclamped thereto by the sleeve 48 being open on one side and closeable by a hand adjustable bolt 52. A leg portion 54 extends from the sleeve 48 and terminates in another leg portion 56 providing the parallel bar. A cross element 58 interconnects the legs 54'and 56 of the handle .unit 44 and a cap element 60 is provided on the outer end of the leg 56. A U-shaped upwardly facing support bracket 62 extends diametrically opposite the cross element 58 from the sleeve 48 to detachably receive the outer ends of oppositely extending pivot shafts 64 on the body frame 46 as seen in FIG. 13. Thus, when the handle unit 44 is pivoted to the position of FIG. 5 it functions as a parallel bar exercise device and when it is pivoted to the position of FIG. 13 it provides a support for the slant bed or body frame 46. In each position the structure for the exercise not being utilized is out of the way and does not interfere with the exercise being performed.
The slant bed or body frame 46 as best seen in FIGS. 13 17 includes an upper generally rectangular in shape frame portion 66 which comprises a pair of parallel side frame members 67 interconnected by rounded end members 68 at the upper end and a straight bar 70 adjacent the pivot shafts 64. A hammock type canvas or the like 72 is stretched between the side bars 67 and the end elements 68 and 70 and is secured in place by cord elements 74. The upper body frame portion 66 provides support for the exerciser from thebuttocks to his head.
The lower body frame portion 76 includes converging side frame members 78 extending from the pivotal Him? nIAA shaft 64 and terminating in elongated closely adjacent parallel frame members 80 having caps 82 on their lower free ends. The feet 84 of the exerciser as seen in FIGS. 14 and are held on the lower body frame 76 by a pair of cross members 90 and 92. A stationary block 94 is secured to the members 80 and a threaded adjustment bolt 96 extends parallel therefrom into engagement with slidable blocks 98 and 100 engaging the members 80. Thus, the threaded bolt 96 remains stationary relative to the stationary block 94 but threadably engages the blocks 98 and 100 and as it is I turned will move the blocks 98 and 100 along with the cross bars 90 and 92 upwardly or downwardly between the solid and dash line positions shown in FIG. 17, the
In at least two of the exercises capable of being performed on the exercise unit of this invention are the ex ercises shown in FIGS. 4 and 13 17, the inverted extension exercise and the slant bed exercise respectively and both of these exercises require the use of the specially constructed boots 110 worn on the ankles of the exerciser. These are more specifically covered in applicants US. Pat. No. 3,380,447. The boots 110 include U-shaped books 112 adapted to engage the stationary top cross bar 114 secured to the uprights 12 thereby allowing the exerciser to perform the inverted extension exercise as illustrated in FIG. 4. when the exerciser is utilizing the slant bed 46 the hooks 112 engage the cross bar 90 while the feet 115 of the exerciser rest on I i the cross-bar 92. Depending on the height of the exer- 7 110 positivelyholding him to the body frame by the hooks 112 engaging the cross-bar 90 and his feet 115 engaging the lower cross-bar 92.
The upper cross-bar 114 while normally remaining stationary may be selectively vertically positioned on the poles 12 through operation of the hand adjustable bolts 120 associated with the slidable sleeves 122.
The exerciser unit 10 is cushioned by the sleeves 12 engaging compressable pads 123 disposed between the bottom ends of the uprights 12 and feet 124 as best seen in FIG. 8. A stub shaft 126 extends through the pads 122 and into the hollow uprights 12. The uprights 12 are in engagement with the ceiling 16 as best seen in FIG. 12 by a threaded rod 130 secured to a base plate 132 threadably engaging a sleeve 134 extending into the uprights 12 and held in a given vertical position by cross pins 136 passing through the sleeves 134 and engaging the upper ends of the sleeve 12. Thus, the sleeves 134 telescope into the uprights 12 and are selectively locked in place by the pins 136 while additional adjustment is accomplished by rotating the threaded shaft 130 into the threaded sleeve 134. The
base plate 132 is secured to the ceiling or the like by a threaded screw 140 which holds a plate 142 in place and allows the base plate 132 to rotate thereabout as the threaded shaft 130 is turned to make the adjustment with the threaded sleeve 134. The sleeves 22 include teflon bushings 131.
In using the exercise device of this invention it is seen .that a variety of different exercises are possible and a representative example of these exercises is illustrated in the drawings and described herein above.
In FIGS; 2 and 3 the springs 32 give assist to the free hanging exercise which can turn' into a chinning exercise with the springs 32 still giving the assist. I
In FIG. 4 the exerciser has positioned himself in an inverted position with the hooks 112 of his boots 110 engaging the top cross-bar 114 and the dumbbell type weight unit having the weights 42 may be lowered and raised by the exerciser engaging the bottom cross-bar at the hand gripping stations 28. The springs '32 may or may not be used as desired.
in FIGS. 5 and 6 the parallel dip with assist exercise is being executed and again the springs 32 perform their assisting function while the exerciser engages the handle units 44 and maintains'his feet on the platform The'Exercise of FIG. 7 illustrates a press on the soles of the feet utilizing the weight unit 38 carried on the bottom cross-bar 20. Again, the spring assist provided by the spring 32 may or may not be utilized as desired.
The slant bed of FIGS. 13 17 involve placing the pivotal axial shafts 64 and the U shaped support brackets 36- (FIG. 9) when the handle units 44 are turned outwardly. The heighth may be selectively positioned by adjustment through the handle 52. The exerciser having secured the boots 110 to each of his legs then steps onto the body frame and engages the hooks 1 12 on the cross-bar with his feet bearing against the cross-bar 92. The exerciser then may shift his arms towards his head to cause him to tip to an inverted position as seen in FIG. 14 or swing his arms towards his sides to cause him to pivot to an upright position as seen in FIG. 15. Leaning against the slant bed starts the slow motion to a horizontal position and with a slow movement of the arms up over the head the inversion action begins. As indicated the bringing of the arms back to the sides returns the slant bed back to its starting position. Arm action can hold any position by stopping arm motion. It is the action of the-arms only, that controls the entire movement from start to finish.
