The disclosure will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements, in which:
The drawings are not necessarily to scale and certain features may be shown exaggerated in scale or in somewhat schematic form in the interest of clarity and conciseness.
Embodiments disclosed herein provide a system, an apparatus, and a method for a leverage training sled system 100. In particular, embodiments disclosed herein provide a leverage training sled system 100 that can be easily utilized to train players of sports to better use leverage and fast twitch muscles. A leverage training sled system 100 includes a bladder member 24 positioned between the contact member 20 and the upright member 18. The bladder member 24 acts to absorb the impact that the player imparts to the leverage training sled system 100 during training sessions and provides resistance to said player. The bladder member 24 is generally positioned near a lower portion of the contact member 20 such that the player must impact the contact member 20 on or near the contact member's 20 lower portion to effectively move the leverage training sled system 100 a distance.
Reference is now made to
The opposed pair of sliding members 10 can have a cross sectional shape of a circle, octagon, hexagon, or any other suitable shape such that the siding members do not substantially prevent the leverage training sled system 100 from sliding across the ground when a player imparts a force to the leverage training sled system 100. The cross members 12 function to connect one sliding member 10 to another sliding member 10. The cross member 12 also functions as support for the deck portion 16.
The upright member 18 is rigidly attached to either the cross member 12 or the deck portion 16 such that the upright member 18 can support the bladder member 24 during training sessions and delimit the range of travel that the contact member 20 may move. In some embodiments, the upright member 18 may also have portions that extend horizontally to either side of the contact member 20. The horizontally extending portions may also have a padded member 36 affixed to the front of their respective faces. Such configuration may be necessitated when beginning training sessions with players of different positions. For instance, such a configuration may be necessary when training a player who plays as a defensive lineman. Such horizontal extending portions of the upright member 18 may not be necessary for all players or all positions.
The horizontally extending portions of the upright member 18 may be adjustable vertically on the upright member 18. The horizontally extending portions can have hooks or pins that interface with corresponding through holes or recesses in the upright member 18 so that a horizontally extending portion can be positioned at one height then moved up or down to another height.
The deck portion 16 can be positioned on top of or adjacent to some or all of the cross members 12. The deck portion 16 functions as a platform to provide the coach or trainer an up-close vantage point of the player during the training session. Other embodiments omit the deck portion 16 to reduce the overall weight of the leverage training sled system 100.
The contact member 20 is pivotally attached to a lower portion of the leverage training sled system 100. In the depicted embodiment, the contact member 20 is attached to the pivot member 26 with a pivot pin 28 that extends through a housing 34 of the pivot member 26 and through holes formed in pivot tabs of the contact member 20. The contact member 20 is configured to be struck by a player during a training session, then pivot towards the upright member 18. The bladder member 24 is connected to a lower portion of the contact member 20 to incentivize the player to strike the contact member 20 at a similar or lower height. The higher up the player strikes the contact member 20, the more force the player will have to strike with to achieve a similar result of a player striking with less force but at a lower position of the contact member 20.
Reference is now made to
The increased friction provided by the friction increasing member 22 enhances the stability of the coach standing on the deck portion 16 making it less likely that the coach will slip or fall off of the deck portion 16 while the leverage training sled system 100 is in use. Any suitable kind of friction increasing member 22 can be utilized such as, but not limited to, anti-slip tape or a textured paint.
Reference is now made to
However, in other embodiments, the bladder member's 24 position can be adjusted vertically, such that the bladder member 24 can easily be positioned up or down on the contact member 20 or the upright member 18. To move the bladder member 24 vertically, a track system is affixed to the contact member 20 and a second track system is affixed to the upright member 18, where both track systems are configured to a set number of positions that the bladder member 24 can be set at. The pair of track systems can both be set at the same height or at different heights depending on user preference.
Reference is now made to
The pivot pin 28 can be coupled with a retention member 30 such that the retention member 30 prevents the pivot pin 28 from sliding out of the pivot member 26 unexpectedly during player training sessions or other situations where the pivot pin 28 is intended to support the contact member 20.
In certain embodiments, the retention member 30 can be coupled to and removed from the pivot pin 28 without incurring permanent damage. The retention member 30 can be a female threaded member such as a nut. The pivot pin 28 can have a male threaded end such that the retention member 30 can thread on to the male threaded end of the pivot pin 28.
If the pivot pin 28 is removed from the pivot member 26 and the bladder member 24 is de-coupled from the contact member 20, the contact member 20 can be removed such that the leverage training sled system 100 is in a more compact form for shipping or storage.
In the embodiment of the pivot member 26 depicted in
Reference is now made to
In an embodiment, the bladder member's 24 internal pressure can be adjusted with a bulb pump, or other manual pressure pump, combined with an air release valve and a pressure gauge. In this embodiment, the coach or trainer can increase the internal pressure of the bladder member 24 by pumping the bulb pump until the pressure gauge reaches a desired pressure. The coach or trainer can alternatively decrease the internal pressure of the bladder member 24 by opening the air release valve until the pressure gauge reaches a desired pressure.
According to some embodiments, the bulb pump or manual pump is replaced with an electric pump. In such embodiments, the coach can set a desired pressure on the pump, and the electric pump be configured to maintain that set pressure without further input from the coach or user. The coach can also alter the set pressure of the electronic pump such that the internal pressure of the bladder member 24 is altered for each different player and their respective ability level.
Other embodiments of the leverage training sled system 100 include a plurality of bladder members 24. The plurality of bladder members 24 can be positioned in line vertically with respect to one another, such that one bladder member 24 is positioned higher than the other bladder member 24. The plurality of bladder members 24 can alternatively be positioned in line horizontally with respect to one another. In these embodiments, both bladder members 24 are positioned at approximately the same height relative to the contact member 20 and the upright member 18. In such embodiments, the bladder members 24 can be sized smaller than with embodiments that only utilize a single bladder member 24. The utilization of multiple bladder members 24 increases the safety of the use of the leverage training sled system 100 as one bladder member 24 may fail and the remaining bladder members 24 prevent the contact member 20 from collapsing into the upright member 18 unexpectedly during use.
The bladder member 24 can be filled with any suitable fluid, in either gaseous or liquid state. Many embodiments utilize air at ambient temperature and humidity as the fluid filling the bladder member 24. In embodiments where a bladder member 24 is filled with a fluid denser than ambient air such as water, the bladder member 24 offers more resistance to the player when the player impacts the contact member 20. In embodiments where the bladder member 24 is filled with a fluid that is less dense than ambient air such as neon gas, the bladder member 24 offers less resistance to a player. Any type of suitable fluid can be utilized within the bladder member 24, the examples listed herein are intended to be non-limiting and merely exemplary for explanatory purposes.
In other embodiments, a sensor system can be added to the leverage training sled system 100. The sensor system can be configured to read or record a value associated with the impact of a player onto the leverage training sled system 100. The sensor system can be embedded within the front padded member 36 to record the force of the impact that the player imparts to it. The sensor system can also be configured to output the reading of the force to a display in real time. The display can be communicatively connected to the sensor system via a physical wire, or it can be wirelessly connected.
The sensor system can also be communicatively coupled to a visual indicator light in the same manner as the sensor is communicatively coupled to the display. The visual indicator light can be set to display different sets of colors associated with different values recorded by the sensor system. As such, after a player imparts a force to the leverage training sled system 100, the visual indicator light will turn on and shine a color associated with the level of force that the player just imparted to the system. This provides instant feedback to both the player and the coach as to the player's performance. As a non-limiting example, for force values that are below a coach's expectations, the visual indicator light will shine red, yellow for values that meet expectations, and green for exceeding expectations. The visual indicator light is not limited to only three colors or those color criteria.
The sensor system can also be configured register which player is training on the leverage training sled system 100 at any point in time. The player would have a transmitter embedded within some portion of the players gear, for example, a football player's helmet, and the transmitter would transmit the player's information to the sensor system before the player begins training with the leverage training sled system 100. The sensor system can then output force values for specific players or specific training sessions to a database to further analyze the player's performance.
In embodiments that utilize an electric pump to set and maintain the internal pressure of the bladder member 24, the sensor system can also be communicatively coupled to the electric pump. In such embodiments, the sensor system can register which player is about to begin a training session with the leverage training sled system 100 and automatically adjust the internal pressure of the bladder member 24 to that specific player's ability level.
Alternatively, the coach can set the pressure of the electronic pump and have the difficulty level that bladder member 24 is set to displayed by a player facing display or light. Such a display could display different words or phrases associated with different internal pressures that the bladder member 24 can be set at.

The various components of the leverage training sled system 100 can be connected to one another via welding techniques or with removable fasteners. In embodiments where the leverage training sled system 100 is assembled utilizing removable fasteners, the leverage training sled system 100 can be shipped to a user or destination unassembled, then assembled on site. Such a configuration can enhance the shipping efficiency of the leverage training sled system 100 as the leverage training sled system 100 can be safely packaged together in a more compact form factor than would otherwise be available if the leverage training sled system 100 was fully assembled.
In other embodiments, the leverage training sled system 100 can be pre-assembled prior to delivery to the site of its use.
