Definitions

  • This invention relates generally to exercise equipment and more particularly to a multipurpose self spotting weight lifting apparatus.
  • Exercise equipment generally falls into one of two main categories.
  • a first category of exercise equipment is primarily concerned with improving the
  • cardiovascular system by performing rapid repetitious movements to induce deep breathing and rapid pulse rate.
  • Exercise equipment of the second category is more concerned with improving muscle tone and increasing muscle mass.
  • Weight training generally belongs to the second category.
  • Free weights usually include a long steel bar provided with a number of disk shaped weights and collars for positioning the weights on the bar. Free weights are often used with a weightlifting bench.
  • the invention comprises a weight lifting station having a compound bar including a central bar within a sleeve centrally positioned on the central bar. Disk weights are positioned on each end of the bar. Two sliders are attached to the bar, one on each end of the bar, which are slidably mounted on vertically oriented guide posts. Each vertical post has a vertical row of locating holes. The sleeve centrally located on the center bar extends almost to each vertical post.
  • Two "L"shaped stops are attached to the sleeve, one at each end of the sleeve so that when the sleeve is rotated by a rum of the users wrist, each stop is brought into engagment with one of the locating holes in the guide posts.
  • the stops thereby provide a weight lifter with a method of self spotting.
  • An additional pair of independent stop pins are also attachable to the posts for supporting the bar at any lower position for starting the exercise.
  • the user can perform his exercise by starting the lift from the lowermost position which is where the independent stop pins are located, then secure the bar at any intermediate height by simply turning his wrist to rotate the spotter stops into adjacent apertures.
  • a problem with the Dawson apparatus as disclosed is that since the safety stop pins are completely separable from their respective vertical posts, they can be disengaged from the uprights during the exercise leading to great distress to the user. Another problem with the separable stop pins as disclosed is that one or both of the pins may be lost so that a user may be tempted to use the apparatus without using the independent stop pins. Yet another problem with the independent stop pins as disclosed is that these stop pins must absorb great impact on those occasions when the user collapses under the exhaustive effort of performing an exercise so that the bar comes crashing down on the stop pins. This ultimately leads to distortion of the posts and stops and unreliable attachment of the stops to the posts as well as sticking of the guides on the uprights.
  • the Dawson invention further discloses a cable attached at one end to a pulldown bar and extending over an overhead fixture of pulleys and down to a hook which may be detachably engaged with the center of the compound bar.
  • the user pulls down on the pulldown bar thereby lifting the compound bar with weights in order to perform the exercise.
  • the problem with this arrangement is that during the course of the exercise, the stop pins can swivel into engagement with the posts thereby inadvertently locking the compound bar while the user is trying to perform his exercise with the pulldown.
  • An L shaped bar forming a locking pin is attached to each end of the bar sleeve that swings and engages one of the apertures when the bar sleeve is rotated so the user may secure the weight bar in a vertical location by simply rotating the bar sleeve on the bar.
  • a plate having several threaded holes is attached to each sleeve. Pins screwed into the appropriate one of these holes provides that the adjustable stop be arbitrarily secured in any one of three conditions.
  • each spotter stop is secured firmly to its respective upright so that the user can perform, e.g., pullups without concern that the bar will become loose while he is performing his exercise.
  • the spotter stop is secured remote from engagement with the upright thereby ensuring that the user can perform exercises with a pulldown bar attached by a cable to the weight bar without concern that the spotter stops will inadvertently engage with the upright and interrupt the user during his exercise.
  • the sleeve is confined to rotate over a very small range including engagement with the upright thereby avoiding the necessity of excessive, uncontrolled rotation of the wrist in order to lock the weight bar in position.
  • a safety stop is slidably mounted on each upright which may be engaged with any of the holes in the column of holes thereby providing a lower limit to the location of the weight bar sliding on the uprights.
  • a spring is mounted on each safety stop providing cushions that soften the impact of the weight bar contacting the safety stops.
  • the slider sleeves are constructed so as to prevent interference of each spring with its respective adjustable stop.
  • Fig. 1 is a perspective view of the weight lifting station of this invention.
  • Fig. 2 is a sectional view of the slider construction.
  • Fig. 3 shows the weight station used to perform bench presses.
  • Fig. 4 shows a second embodiment of the slider and stop.
  • fig. 1 shows an exercise apparatus in accordance with the present invention including a weight lifting station 20.
  • the weight lifting station 20 includes a pair of vertrically oriented guide posts 24 and 26, a horizontally oriented weight bar 28, a base assembly 30, and an upper brace assembly 32.
  • a pair of post sliders 34 and 36 are telescoped over guide posts 24 and 26 respectively.
  • a support beam assembly 38 is attached to brace assembly 32 and pull-bar assembly 40 is engagable with support beam assembly 38 and a sleeve 29 around bar 28.
  • guide posts 24 and 26 are preferably square tubular members provided with a plurality of vertically spaced apertures 42. It is an embodiment of this invention that the inner surfaces 44 of sliders 34 and 36 are coated with high density polyethylene while the outer surface 43 of the upright posts are coated with epoxy. Both of these polymer surfaces forming a sliding interface will permanently retain silicone lubricant in contrast to metal surfaces. The coefficient of friction of the interface is thereby permanently and dramatically reduced, and provides a smoother sliding action.
  • Plates 46 and 48 are welded to post sliders 34 and 36 respectively having holes 50 receptive to the weight bar 28 which is welded to each of the plates 46 and 48 and thus, weight bar 28 is horizontally supported for vertical movement along the guide posts 24 and 26.
  • a bar sleeve 29 is slidably telescoped over bar 28 between plates 46 and 48.
  • the bar sleeve 29, which is free to rotate around bar 28, is provided with knurling at hand hold locations 52.
  • Sleeve 29 is also provided with a pair of slider stops 54 and 56 which are adjacent to the guide posts 24 and 26 respectively.
  • slider stops54 and 56 are substantially "L"shaped pins and have one leg attached to sleeve 29 and another leg engagable with apertures 42 of the guide posts 24 and 26.
  • the apparatus may be used to perform numerous exercises.
  • the advantages of the apparatus are particularly illustrated with reference to performing the bench press shown in fig. 3.
  • the user is shown lying on bench 120 placed between the posts with his hands grasping the weight bar.
  • the exercise is performed by raising the bar in a reciprocating sliding motion of the sliders on the uprights.
  • Fig. 1 shows safety rests 33 and 35 to be positioned on each upright post.
  • Each rest comprises a short section of sleeve that telescopes onto each upright post providing that the rest may not be removed from the post and possibly be misplaced.
  • Each rest is secured by a pin 37 through a hole in the rest 33 and 35 aligned with a selected one of the apertures in the post 24 and 26 respectively.
  • a spring 84 is telescoped over each guide post 24 and 26 and rests on the top of the safety rest 33 and 35 providing that impact of the post slider 34 or 36 on the rest 33 or 35 is cushioned.
  • Fig. 2 shows post sliders 34 and 36 extending downward on the respective post so that a hole 39 in the slider 34 or 36 can be aligned with an aperture 42 in the post 24 or 26. . Therefore the leg of the "L" shaped stop 54 or 56 is inserted through BOTH the hole 39 in the slider AND one of the apertures 42 in th post in order to secure the slider in its vertical position.
  • the spring 84 therefore contacts the lower end 59 of the slider 34 or 36 when the weight bar 28 descends to the rest 33 or 35 thereby presenting a positive cushioning effect and preventing inadvertent engagement of the spring 84 with the leg of the respective stop 54 or 56.
  • Fig. 2 shows plates 46 and 48 each to have a catch means for maintaining the stops 54 and 56 in a selected one of three orientations indicated in phantom in fig. 2.
  • the catch comprises catch three holes 61, 63 and 65, for receiving catch pins (not shown in fig. 2 but shown in fig. 4, item 130) which selectively confine the orientation of the stop pins 54 and 56.
  • catch pin When the catch pin is in the lower hole , the leg of the stop 54 or 56 is secured in the aperture 42 in the post
  • the weight bar 28 is thereby fixed in a selected vertical location providing that the user can hang from the weight bar 28 to perform exercises such as pullups without concern that the stop 54 or 56 will be accidentally disloged from its aperture 42 resulting in movement of the weight bar.
  • the leg of the "L"shaped stop 54' (or 56 ') is confined to rotate between a first location where it just clears the edges of the aligned hole in the slider and aperture in the post and a second location where the leg is in the aligned hole 39 and aperture 42 thereby locking the weight bar 28 in its vertical location.
  • This construction provides greater safety in spotting the weight and also enables the user to exert greater force in performing presses becauses the catch pin confining the orientation of the sleeve 29 in this limited range of positions prevents inadvertent excessive rotation of the wrists by the user in locking and unlocking the bar.
  • the stops 54 and 56 are secured remote from the position where they can inadvertently immobolize vertical movement of the bar.
  • the weight bar 28 is free to slide vertically as required when the user is performing pulldowns by pulling on pulldown bar 40 secured to one end of cable 106 which passes over an overhead pulley system 32 and has its other end 108 hooked to the sleeve 29 on the weight bar 28.
  • a base assembly 30 includes a "C" shaped main base portion 64 which is in contact with a floor surface 66. Attached to the leg portions 68 and 70 of main base 64 are stabilizing assemblies 72 and 74. The stabilizing assemblies are provided with flanges adapted to be attached to a wall surface.78. Stabilizing assemblies 72 and 74 arc further provided with weight supporting rods 80 to support a plurality of disk shaped exercise weights such as those shown at 82.

Abstract

Un ensemble d'haltérophilie (20) comprend une paire de montants de guidage (24, 26) permettant de guider verticalement un ensemble barre à disques (28, 29, 54, 56, 46, 48). L'ensemble barre à disques comprend une barre (28) à poids, un manchon (29) disposé de manière télescopique sur la barre (28) ainsi que des butées (54, 56) fixées au manchon (29) au moyen de goujons d'arrêt (130) afin de retenir les butées (54, 56) dans une orientation parmi les trois possibles (61, 63, 65). Selon une orientation (61), les goujons d'arrêt (130) bloquent les butées (54, 56) en appui contre des ouvertures (42) pratiquées dans le montants (24, 26), empêchant ainsi le mouvement vertical de la barre (28) à partir d'une position verticale choisie. Selon une deuxième orientation (63), les goujons d'arrêt (130) bloquent les butées (54, 56) en une position éloignée desdites ouvertures (42), dont elles sont ainsi libérées, afin de permettre à l'ensemble barre (28, 29, 54, 56, 46, 48) de coulisser verticalement sur les montants de guidage (24, 26). Selon la troisième orientation (65), l'utilisateur peut faire tourner manuellement le manchon (29) sur une petite distance limitée par les goujons d'arrêt (130), entre une position dans laquelle les butées (54, 56) sont entièrement en contact avec les ouvertures (42), et une position dans laquelle les butées (54, 56) en sont éloignées, permettant ainsi à l'utilisateur d'avoir accès à une fonction 'auto-pareur' de l'appareil.
