Weightlifting blocks, otherwise known as jerk or pull blocks, are used in exercise routines and generally serve to aid in weightlifting training. Typically, a weightlifting block or a stack of weightlifting blocks is provided on either side of an athlete attempting to lift barbell equipment. The athlete begins a pull exercise by lifting the equipment from the weightlifting blocks, and then proceeds with a desired weightlifting motion. Upon completion of the motion, the athlete returns the weightlifting equipment to rest on the weightlifting blocks, unloading the athlete. The weightlifting blocks allow for removal of additional stress that would be caused by having to place the weightlifting equipment all the way to the ground, and thus enable the athlete to focus on weightlifting form and movement specifics during training. The blocks also allow for higher repetitions during a session. Weightlifting blocks also aid in allowing an athlete to continue training after an injury, such as a sore or injured lower back or knee.
Additionally, weightlifting blocks are designed to have substantial weight so that the blocks do not bounce when in use; wood blocks often weight in excess of 50 lbs and metal blocks in excess of 200 lbs. Because of their substantial weight, weightlifting blocks often occupy a dedicated location in a gym, taking up valuable floor space whether or not the blocks are in use. Carts with wheels, such as dollys, are typically used to move the blocks; however, removal of the carts from underneath the blocks can be cumbersome and difficult.
A weightlifting apparatus is provided. In one aspect, the apparatus comprises at least one platform having a top surface and a bottom surface and at least one wheel attached to the bottom surface. At least one platform is rotatably mounted to one of the plurality of sidewalls and an activation lever is configured to lift the at least one platform from an inactive position to an active position. In the active position, the at least one wheel extends beyond a bottom edge of the plurality of sidewalls. In the inactive position, the at least one wheel is retracted within the block and does not extend beyond the bottom edge.
In another aspect, an example weightlifting block assembly includes at least one platform movable from a first position to a second position, a lever operably connected to and horizontally pivotable about the at least one platform, and a plurality of wheels affixed to the at least one platform. The plurality of wheels are activated when the platform is in the second position.
In a further aspect, an example method involves providing a weightlifting block having at least one platform connected to an interior wall of the weightlifting block and rotatable with respect to a pivot, and a lever rotatably mounted to the at least one platform. The method further involves translating the lever in a first direction to cause the at least one platform to rotate upon the pivot, and translating the lever in a second direction to lock the lever in an activated position. In the activated position the platforms are positioned such that wheels attached to the at least one platform extend beyond a bottom edge of the weightlifting block.
These as well as other aspects, advantages, and alternatives, will become apparent to those of ordinary skill in the art by reading the following detailed description, with reference where appropriate to the accompanying drawings.
Example weightlifting apparatuses and methods are described herein. Any example embodiment or feature described herein is not necessarily to be construed as preferred or advantageous over other embodiments or features. The example embodiments described herein are not meant to be limiting. It will be readily understood that certain aspects of the disclosed apparatuses and methods can be arranged and combined in a wide variety of different configurations, all of which are contemplated herein.
Furthermore, the particular arrangements shown in the Figures should not be viewed as limiting. It should be understood that other embodiments may include more or less of each element shown in a given Figure. Further, some of the illustrated elements may be combined or omitted. Yet further, an example embodiment may include elements that are not illustrated in the Figures.
Example embodiments disclosed herein generally relate to weightlifting blocks for use with weightlifting and associated exercise training. Weightlifting generally includes a steel bar, known as a barbell, holding one or more discs of different weights. The barbell is typically loaded incrementally with additional weights throughout an exercise and in a competition event.
There are different types of lifts that can be performed using the barbell; for example, a snatch lift involves the lifter having a wide grip on the barbell and pulling the barbell overhead without pressing out with the arms. Another example lift is referred to as the clean and jerk, wherein the lifter has a narrower grip on the barbell, and during the “clean” the lifter moves the barbell from the floor to a racked position across the lifter's deltoids and clavicles, and during the “jerk” the lifter raises the barbell to a stationary position above the lifter's head, finishing with straight arms and legs and feet in the same plane as the torso and the barbell, without a press out. Variants of these movements can also be performed, such as but not limited to the split jerk, the squat jerk, and the power clean.
Athletes often train to lift weights using weightlifting blocks to focus on portions or aspects of an entire lifting movement instead of performing the complexity of the entire movement. Advantageously, using weightlifting blocks allows a lifter to initiate a movement from the same position every time as opposed to initiating a movement from a hang position which results in variance for starting positions. Dissimilar starting positions can impact technique training. Further, after each lift, the barbell is returned to the block, unloading the lifter who drops the weight for the next lift without needing to continue all the way back to the ground; removing this stressor enables the lifter to focus entirely on his or her movement and the intended training.
Although weightlifting blocks have many advantages as previously discussed, the blocks are heavy and cumbersome, with metal blocks typically weighing as much as 200 lbs-400 lbs, and are thus difficult to move and store when not in use.
The block 200 may take various forms, which may be currently well-known or yet to be developed. For instance, the block 200 may be made of, at least in part, a high-strength material, such a metal like steel, or may be made of wood. In one example embodiment, the block 200 is modular and configured to be stackable. Additionally, the size of the block 200 may vary depending upon the particular implementation. The block 200 may have a top surface, and the four sidewalls 202, 204, 206, and 208, which define an interior. Block 200 may have an open bottom defined by a bottom edge along the perimeter of the four sidewalls.
Two platforms 240 are depicted in
Four wheels 230 are shown in
Cut-out 212 extends through sidewall 202, and allows access to the interior of block 200. Cut-out 212 is shown as having a vertical portion 213 and a horizontal portion 215, forming, as shown in
Lever 210 is connected to a top surface of one of the platforms 240 and is anchored to the platform 240 via a bolted bushing 250. Preferably, lever 210 is connected to the platform that is attached to the sidewall opposite the sidewall comprising cut-out 212. Although a bolted bushing is depicted in the embodiments of
It should be understood that variations on the illustrated weightlifting block assembly are possible. For example, the weightlifting block may take on various sizes and/or shapes, and be constructed from various materials, depending upon the implementation. It may also be activated through a number of mechanisms or powered systems other than the currently described method with a user's foot.
As shown by block 610, method 600 involves providing a weightlifting block having at least one platform connected to a sidewall of the weightlifting block and rotatable with respect to a pivot, and a lever rotatably mounted to the at least one platform. The lever is rotatable with respect to a pivot on the platform. The weightlifting block may be the weightlifting block 200 as described with respect to
Then at block 620, method 600 involves translating the lever in a first direction to cause the at least one platform to rotate upon the pivot. The first direction may be a vertical direction and the lever may translate within the space provided by a through-hole in a sidewall, such as the cut-out 212 as described with respect to
At block 630, method 600 involves translating the lever in a second direction to lock the lever in an activated position, wherein in the activated position, the platforms are positioned such that the wheels extend beyond a bottom edge of the weightlifting block. The second direction may comprise the lever pivoting about the bushing in a horizontal direction. When the lever pivots in a horizontal direction, the lever moves within a horizontal section of the cut-out, and may remain within the horizontal section of the cut-out to lock the platforms into place in the activated position. Other example embodiments may incorporate alternate locking mechanisms that do not require this additional step of translation a lever in an additional direction, and employing a single direction movement with a lockout mechanism and similar release.
