DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIG. 1-7, the present invention features a barbell positioning system. The barbell positioning system 100 of the present invention controls the positioning of weights (e.g., the ascent and descent of weights), preventing weights from being quickly dropped to the ground. The barbell positioning system 100 of the present invention can help prevent damage to equipment as well as injury to the weight lifter.
The barbell positioning system 100 of the present invention comprises a frame 110. The frame 110 may be generally cuboidal, however the frame 110 is not limited to this shape. Generally, the frame comprises a first front post 120a, a second front post 120b, a first back post 130a, and a second back post 130b. The top end of the first front post 120a is connected to the top end of the first back post 130a via a first connecting post 140a, and the top end of the second front post 120b is connected to the top end of the second back post 130b via a second connecting post 140b. A crossbar may extend from the first connecting post 140a to the second connecting post 140b. 
The frame 110 may be constructed in a variety of sizes. For example, in some embodiments, the frame 110 is between about 8 to 10 feet in height as measured from the bottom ends of the front posts 120 to the top ends of the front posts 120. In some embodiments, the frame 110 is between about 10 to 12 feet in height as measured from the bottom ends of the front posts 120 to the top ends of the front posts 120. In some embodiments, the frame 110 is between about 4 to 8 feet (e.g., 5 feet) in width as measured from the first front post 120a to the second front post 120b. In some embodiments, the frame 110 is between about 4 to 10 feet in length (e.g., 6 feet, 8 feet) as measured from the first front post 120a to the first back post 130a. The frame 110 is not limited to the aforementioned dimensions.
A set of weights 150 is positioned in between the first back post 130a and second back post 130b. The set of weights 150 is slidably attached to a set of sliding posts 155 and a pin pulley 158. The set of weights 150 is divided into weight plates with a fixed amount of weight, each plate comprising a pin slot adapted to receive a pin. When the pin is inserted into the pin slot, it engages the pin pulley to which the weights are slidably attached. Such sets of weights with pin slots are well known to one of ordinary skill in the art. For example, a user can select an amount of weight and slide a pin into in the pin slot that will correspond to that amount of weight. For example, if each weight plate weighs 10 pounds and the user wishes to select 30 pounds, he/she would slide the pin into the weight plate that is the third plate from the top. The selected plate as well as the two plates above total 30 pounds.
The pin pulley 158 to which the set of weights 150 is slidably engaged extends through the connecting posts 140 and down through a portion of the front posts 120. For example, the pin pulley 158 splits into a first arm 158a that extends through the first connecting post 140a and first front post 120a and a second arm 158b that extends through the second connecting post 140b and the second front post 120b. The pin pulley 158 (e.g., the arms) may engage various pulley components disposed in the front posts 120, back posts 130, and/or connecting posts 140.
A first sliding base 160a is slidably disposed on the first front post 120a, and a second sliding base 160b is slidably disposed on the second front post 120b. The sliding bases 160 are adapted to slide up and down the respective front posts 120. The first arm 158a of the pin pulley 158 engages the first sliding base 160a, and the second arm 158b of the pin pulley 158 engages the second sliding base 160b. The set of weights 150 thus functions as a counterweight to weight added to the sliding bases 160.
As shown in FIG. 5, the sliding bases 160 each comprise an outer frame 161 that wraps around the respective front post 120. Extending forwardly from the front of the outer frame 161 is a hook component 162. The hook component 162 is adapted to hold up the bar of a barbell. Disposed in the center of the hook component 162 is a pivot center 164 (having an inner end facing the outer frame 161 of the sidling base 160 and an outer end extending away from the outer frame 161 of the sliding base 160). The outer end of the pivot center 164 is pivotally attached to the hook component 162 (in the center of the hook component 162) via a pivot component 164a (e.g., a pivot pin, etc.). The pivot center 164 is adapted to pivot with respect to the hook component 162 surrounding the pivot center 164. For example, the inner end of the pivot center 164 pivots upwardly with respect to the outer end of the pivot center 164.
In some embodiments, a first spring 170a is disposed in the first front post 120a and a second spring 170b is disposed in the second front post 120b. In some embodiments, the first spring 170a (e.g., the bottom end) is attached to the first sliding base 160a and the top end of the first spring 170a faces (but is not attached to) the top end of the first front post 120a. In some embodiments, the top end of the first spring 170a is attached to the first arm 158a of the pin pulley 158 and the bottom end of the first spring 170a faces (but is not attached to) the first sliding base 160a. In some embodiments, the second spring 170b (e.g., the bottom end) is attached to the second sliding base 160b and the top end of the second spring 170b faces (but is not attached to) the top end of the second front post 120b. In some embodiments, the top end of the second spring 170b is attached to the second arm 158b of the pin pulley 158 and the bottom end of the second spring 170b faces (but is not attached to) the second sliding base 160b. The springs 170 may help to provide shock absorption. For example, once a barbell 102 has been dumped off the sliding base 160, the set of weights 150 retracts the sliding base 160 and the springs 170 help prevent damage to the set of weights 150 (by providing a cushion between the sliding bases 160 and top ends of the front posts 120). The springs 170 may also help to ensure smooth movement of the sliding bases 160 along the respective front posts 120. The springs 170 may be sufficiently stiff and long so to prevent a violent collision of the set of weights 150, but not so much as to foul the mechanism of the sliding base 160. An alternate embodiment of the present invention may employ a hydraulic piston for this function, which may connected to both the respective top ends of the front posts 120 and sliding bases 160.
A plurality of pinholes are disposed in each the first front post 120a and second front post 120b. The pinholes are adapted to receive a pin 180. The pins 180 may function to limit how high and how low the sliding bases 160 can slide along the respective front posts 120. The pins 180 may also function to provide a base for the springs 170 (e.g., shock absorbers) to push off of as well as to enable a user to choose an appropriate height for the sliding bases 160.
A first resting base 190a is disposed (e.g., slidably or removably) on the first front post 120a positioned below the first sliding base 160a. A second resting base 190b is disposed (e.g., slidably or removably) on the second front post 120b positioned below the second sliding base 160b. The resting bases 190 are adapted to be positioned along the respective font posts 120 and secured via locking pins 198 (e.g., twisted pins) that engage pinholes in the front posts 120. For example, a user can select an appropriate position for the resting bases 190 on the front posts 120 (e.g., near the bottom ends of the front posts 120, near the middle of the front posts 120, etc.) and secure the resting bases 190 in place via the locking pins 198.
Generally, the resting bases 190 each comprise a vertical plate 191 that engages the respective front post 120 (via the locking pins 198) and a tray 194 that extends generally perpendicularly to the vertical plate 191 outwardly from the vertical plate 191. The tray 194 functions to hold the barbell 102 when the barbell 102 is moved from the sliding base 160 to the resting base 190. The trays 194 of the resting bases 190 may be longer (e.g., extend further away from the front posts 120) than the sliding bases 160 (e.g., see FIG. 6A and FIG. 6B).
A tray hook 195 may be disposed on the outer end of the tray 194 to help prevent the barbell 102 from rolling off of the tray 194 portion of the resting base 190. The resting bases 190 each also comprise a top extension 193 that extends upwardly from the tray 194. The top extensions 193 are generally positioned next to the front posts 120 (e.g., opposite the tray hooks 195). The top extensions 193 may be a generally triangular or pyramidal in shape, however the top extensions 193 are not limited to these shapes. The shape of the top extensions allows for the sliding bases 160 (e.g., the pivot centers 164) to perform its function. For example, when the sliding bases 160 slide downwardly along the front posts 120 the sliding bases 160 contact the top extensions 193 of the resting bases 190. The top extensions 193 force the pivot center 164 of the sliding bases 160 to pivot (e.g., pivoting upwardly to roll the barbell 102 off onto the resting base 190, which catches the barbell 102). Thus, any shape that allows for forcing the pivot center 164 to drop the barbell 102 onto the resting bases 190 is conceivable.
To use the system 100 of the present invention, a user selects the amount of weight he/she wishes to lift. Then, the user slides a pin into a pin slot in the set of weights 150 at the back of the frame 110. The weights 150 function as counterweights used to slow down the descent of the barbell 102 when the barbell 102 is placed on the sliding bases 160 (at the top of the lift). Generally, the weight selected on the set of weights 150 should correspond to about the amount to be lifted on the barbell 102. The user then positions the resting bases 190 to a position of his/her choice (e.g., near the bottom ends of the posts 120, near the middle, etc.). The positioning of the resting bases 190 can also be done prior to selecting weight on the set of weight 150. The barbell 102 is lifted (e.g., once, multiple times depending on the exercise); when the user has finished the lifting process, he/she places the barbell 102 on the sliding bases 160. Because of the counterweight (set of weights 150), the barbell 102 is slowly lowered along the front posts 120 on the sliding bases 160. When the sliding bases 160 contact the resting bases 190, the inner ends of the pivot centers 164 of the sliding bases 160 are pivoted upwardly about the pivot components 164a via the top extensions 193 of the resting bases 190, allowing the barbell 102 to be dumped onto the resting bases 190. The sliding bases 160 slowly return to their original position, and the barbell 102 is ready for another lifting set. The pivot centers 164 of the sliding bases 160 may resume their original positions prior to being pivoted upwardly via the top extensions 193 of the resting bases 190.
As used herein, the term “about” refers to plus or minus 10% of the referenced number. For example, an embodiment wherein the frame 110 is about 5 feet in width includes a frame 110 that is between 4.5 and 5.5 feet in width.
As shown in FIG. 7, the counterweight (e.g., set of weights 150) may be replaced by a spring tension system 710 or a rubber band-type system (both systems must be adjusted, e.g., via adjustment handles 720, by the user to choose appropriate weights). Such systems are well known to one of ordinary skill in the art. In some embodiments, the system 100 is bolted to the ground surface, which may help to stabilize the system 100 (e.g., if a spring-tension system or rubber band-type system is used and there are no counterweights to help balance the system 100).
