## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/286,034, entitled “TURN WEIGHT PLATE,” filed on Dec. 14, 2009, the disclosure of which is incorporated herein by reference.


BACKGROUND
The present disclosure contemplates that weight training has been in existence for thousands of years. Uses of weight lifting may relate to health issues, sports performance, rehabilitation, and leisure activity. The advancement of health brings the development of weight lifting techniques. A better athlete may be created partially through improved weight resistance techniques. Weights may be used to help rehabilitate injuries. Further, weight lifting has grown and developed simply through leisure and professional weight lifters.
Current weight plates in the weight room are all of similar design, existing in weight plate increments of forty-five, thirty-five, twenty-five, ten, five, and two and a half pounds. These designs typically need a large area for storage, have high costs, and are inconvenient to use.
Therefore, it is desired that weight plates reduce the storage space requirements and be more convenient to use.
SUMMARY OF THE DISCLOSURE
This disclosure is drawn to devices, apparatuses, systems and/or methods related to weight plates. Specifically, the disclosed devices, apparatuses, systems and/or methods relate to nested weight plates in which the total weight of the weight plate may be selected using a locking mechanism.

DETAILED DESCRIPTION
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
The present disclosure contemplates that there exists no weight plate design similar to the example embodiments described herein. Current plates in the weight room are of similar design, existing in weight plate increments of forty-five, thirty-five, twenty-five, ten, five, and two and a half pounds. Example embodiments may reduce space needed to store weights in a weight room. Example embodiments may replace all of the weights listed above. Example embodiments may provide a multi-purpose weight plate; uses may be in home gyms and smaller gyms, along with large commercial weight rooms and rehabilitation centers. Example embodiments may prove useful to all members of the weight-training world.
In an example embodiment, a nested weight plate is provided that includes a first weight plate increment, a second weight plate increment configured to receive the first weight plate increment, and a locking mechanism. In some embodiments, the locking mechanism may be a turning mechanism including a screw. The turning screw may be received in the first weight plate increment such that rotation of the screw in a first direction causes the screw to extend into and engage the second weight plate increment. Further, rotation of the screw in a second direction (e.g., opposite the first direction) causes the screw to retract from and disengage from the second weight plate increment. In this manner, a user may select from a first weight or a second weight. In some embodiments, the turning mechanism may also include a turning circle configured to be coupled to the screw. In some embodiments, rotation of the turning circle causes rotation of the screw.
In some embodiments, the locking mechanism may be received in the first weight plate. In some embodiments, the locking mechanism may move freely within the first weight plate. For example, a screw may be inserted through the underside (e.g., bottom) of the weight plate(s) and screwed in place, and then a cap (e.g., a turning circle) may be snapped on the topside (e.g., top) of the weight plates to lock the weight plates together.
In an example with only two weight plate increments, a user may select either the weight of the first weight plate increment only, or the weight of the combination of the first weight plate increment and the second weight plate increment. For example, if a first weight plate increment weighs ten pounds and a second weight plate increment weighs twenty pounds, a user may rotate the screw to select a ten pound weight plate (i.e., the first weight plate increment) or a thirty pound weight plate (i.e., the combination of the first and second weight plate increments). While a basic example of two weight plate increments is described, it is within the scope of the present disclosure that any number (e.g., two, four, ten, one hundred) of weight plate increments may be combined in various embodiments. For example, FIG. 11 depicts an embodiment having four weight plate increments.
In some examples, a third weight plate increment may be configured to receive the second weight plate increment. In some examples, rotation of the screw in the first direction may cause the screw to extend into and engage the second weight plate increment and the third weight plate increment. Rotation of the screw in a second direction (e.g., opposite the first direction) may cause the screw to retract from and disengage from the second weight plate increment and the third weight plate increment.
Example embodiments may include a plurality of weight plates that appear to be only one weight size. With the ability to pull out lesser weights from the greater ones (or greater weights from the lesser ones), it may be possible to compact numerous weight plates into one weight plate. For example, an example greater weight plate may weigh forty-five pounds in total. Such an example weight plate may include a ten pound weight that may be pulled out of a “twenty-five pound” weight which may be pulled out of a “thirty-five pound” plate which may then be pulled out of a “forty-five pound” plate. The weights associated with each plate (e.g., “twenty-five pound”) refer to the total weight of the identified plate and the plates nested therein taken together, rather than the actual weight of the individual plate. It should be understood that weight plate increments may be of any shape (e.g., round, square, oval), so long as the weight plate increments are configured to be nested with one or more other weight plate increment. In some embodiments, nested weight plates may be flush against other weight plate increments. In some embodiments, nested weight plates may not be flush against other weight plate increments.
In some example embodiments, for a lesser weight to be pulled out of a greater weight, a turning mechanism may be turned to a certain position to release that lesser weight. In some example embodiments, when the turning mechanism is turned, it screws upwards and downwards through the inside of the weight plate increments. The weight plate increments may include threading that lines up when the weight plate increments are nested in place. The turning mechanism may be captured in the smallest increment so that it is always included for any weight amount. In some example embodiments, this feature may be provided by cuts in the smallest weight plate increment and a snap on lid (e.g., turning circle) on top of the screw. In some example embodiments, the turning circle may be labeled with weight plate increment indicia so that a user knows how much weight they are using.
An example screw may include a stop before the smallest weight plate increment and/or after the largest weight plate increment so that, when the screw is completely at the top or bottom, the user knows to turn the mechanism the other way. In some examples, the turning circle may be rotatable up to 360 degrees. As the turning mechanism is turned clockwise, the screw may thread down into the greater weights. As the turning mechanism is turned counterclockwise, it may screw back out of the greater weights. When the screw is at its highest point, it may be completely within the smallest weight plate increment. See, for example, FIG. 5. When the screw is at its lowest point, it may be threaded all the way to include every weight plate increment. See, for example, FIG. 4. It is within the scope of the present disclosure that any other types of mechanism may be utilized to combine nested weight plate increments.
In some embodiments, the screw and/or turning circle do not have to lock into place when engaging the next weight plate increment. In such examples, one or more decal on the weight plate increments may identify where to stop turning for the next weight plate increment.
The inside of the screw may be smooth and may correspond to the dimensions of a weight lifting bar so that it can be mounted and/or dismounted from the weight lifting bar.
In some examples, the first stop may correspond to the screw engaging only a first weight plate increment. In some examples, the second stop may correspond to with the screw engaging at least a first weight plate increment and a second weight plate increment.
It should be understood that the locking mechanism described herein is not limited to a turning mechanism. Embodiments including a turning mechanism having a turning circle and screw are described herein for brevity and are not meant to be limiting. Any locking mechanism configured to lock weight plates together may be utilized in some embodiments. For example, in some embodiments, a spring-loaded locking mechanism (in one or more weight plate increment) may be utilized in place of or in addition to a turning mechanism. It should also be understood that the locking mechanism described herein is not limited to the center of the weight plates. The locking mechanism may be located at any location on the weight plates.
Some examples may include one or more handles in and/or on one or more weight plate increments. For example, FIG. 11 depicts two handles on each of four weight plate increments. Some examples may have no handles, while some examples may have handles on all weight plate increments. Some examples may have handles on some weight plate increments, while other weight plate increment have none.
Some example embodiments may include tab(s) and/or cut(s) in individual weight plate increments to aid proper alignment when a weight plate increment is loaded among the other weight plate increments in the plate. In some examples, a first weight plate increment may include one or more tab configured to align the first weight plate increment with a second weight plate increment. The second weight plate increment may include one or more corresponding cut configured to receive the one or more tab. When the tabs are aligned with the cuts, rotational movement of the first weight plate increment relative to the second weight plate increment may be reduced. Such tabs and cuts may also secure the weight plate increment in the appropriate spot and provide a location for the turning mechanism. Since the weight plate increments may be designed to be placed in the correct position, the threads may always line up appropriately. Tab(s) and/or cut(s) may be of any shape, so long as they are capable of aiding proper alignment.
Example materials of the weight plates may include metal, rubber, and/or plastic. Two example plates of different size and weights may meet the needs of most weight lifters. An example heavier weight may weigh about forty-five pounds in total and/or may include weight plate increments of about ten, twenty-five, thirty-five, and forty-five pounds, for example. An example lighter weight may include increments of about two and a half, five, seven and a half, and ten pounds and/or may weigh a total of about ten pounds. It is within the scope of the present disclosure that any sizes, denominations and/or weights of weight plate increments may be combined in various embodiments.
Some example embodiments may include racking system so that the weights may be easily stored and/or so that the increments may be easily and safely placed back into one another. Through a simple cantilever frame, which may include an angled support system, the weights may be simply placed and taken out of their appropriate place with ease.
In some example embodiments, a method of using a nested weight plate having a plurality of nested weight plate increments and a turning mechanism including a turning circle and a screw, is provided. An example embodiment may include inserting the screw into at least one of the plurality of nested weight plate increments, coupling the turning circle to the screw, turning the turning circle to a position associated with a desired weight, and removing a first weight plate increment of the plurality of weight plate increments from a nested second weight plate increment of the plurality of weight plate increments. In some examples, turning the turning circle may include rotating a screw extending at least partially through the first weight plate increment and the second weight plate increment. In some examples, turning the turning circle may include aligning the turning circle with an indicia corresponding to the desired weight.
In some examples, the method may further include mounting the first weight plate increment on a weight bar. In some examples, mounting the first weight plate increment on the weight bar may include extending the weight bar at least partially through the turning circle and the screw.
Turning now to the FIGS., FIG. 1 illustrates an example turn weight plate 100 including weight plate increments 102, 104, 106, 108. Some example weight plates may include a turning mechanism 198 including a turning circle 200, cuts 302, 304, 306, and corresponding tabs 308, 310, 312. The cuts 302, 304, 306 and/or tabs 308, 310, 312 may ensure that the weight plate increments are put back into the correct place and/or orientation so that the threads may line up appropriately.
FIG. 2 illustrates a close-up view of an example turning mechanism 200 in a ten pound weight plate increment 102. Note the indications 402, 404, 406, 408 of how the weight plate increments are to be chosen and how there are stops 410, 412 before and after the appropriate weights. These stop may indicate to the user that the turning circle 198 must be turned the other way for use.
FIG. 3 illustrates threads 420 inside example weight plate increments 102, 104, 106, 108 without the turning mechanism inserted. Note that the threads 420 may not cover the entire length of the inside of the weight plate increments. For example, a recessed section 422 may be provided in the ten pound weight plate 100 for receiving the turning circle 198.
FIG. 4 illustrates a cross-section view of turning mechanism 200 including turning circle 198 and screw 199. In this position, screw 199 engages weight plate increments 102, 104, 106, 108. FIG. 5 illustrates screw 199 engaging only weight plate increment 102. With screw 199 in this position, weight plate increment 102 may be lifted out of and away from the other weight plate increments 104, 106, 108. In some example embodiments, turning circle 198 may remain at least partially recessed within weight plate increment 102 when screw 199 engages only weight plate increment 102. FIG. 6 illustrates example weight plate increments 102, 104, 106, 108.
FIG. 7 illustrates an example screw 199, which may include a latch 199A for engaging turning circle 198. Screw 199 may include external threads 199B.
