The competitive swimming rules allow an athlete (e.g., swimmer) to start numerous types of races from a position external to a swimming pool. In many instances, a starting block is utilized, which is a raised platform disposed adjacent an edge of the pool that supports the swimmer prior to starting the race. Numerous parameters regarding the dimensions and orientation of the starting block are specified by rules and regulations set forth by the swimming governing body.
A swimmer may start from one of numerous positions on the starting block. For example, the swimmer may position both feet adjacent a front edge of the starting block and push off the front edge when diving into the water. In other instances, the swimmer may position one foot (e.g., leading foot) adjacent the front edge of the starting block with the other foot (e.g., trailing foot) set back from the front edge for a “track start.” In track starts, the leading foot contacts and pushes off the front edge, or a front section of the platform, while the trailing foot pushes off a raised portion of the starting block.
Some starting blocks include a raised surface in the form of a back plate and/or other raised surfaces that protrude from the starting block that act as a support surface for the trailing foot as the swimmer pushes off from the starting block. Typical back plates include an inclined or otherwise protruding surface that extends upwardly from the starting block. The swimmer is able to position the trailing foot onto the back plate to provide additional thrust when diving into the pool.
Many back plates known in the art protrude upwardly from an upper surface of the starting block at an incline and extend laterally across the entire width of the upper surface. Additionally, back plates that extend the entire width of the starting block have been used to accommodate swimmers who favor one foot or the other for pushing off. For example, a swimmer pushing off the starting block with the right foot would need a back plate disposed adjacent the right foot. Similarly, a swimmer pushing off the starting block with the left foot would need a back plate disposed adjacent the left foot. Therefore, swimming pools have used elongate back plates that span the width of the starting block to accommodate both types of swimmers.
However, there are some obstacles associated with these back plates due to their positioning and orientation. In particular, the back plate may make it awkward for a swimmer to mount the starting block due to the width of the back plate and the inclined nature thereof. In these instances, the swimmer may be forced to climb onto the starting block over the angled back plate.
Some starting block systems have attempted to address these deficiencies by providing an adjustable back plate. However, these back plates still span the entire width of the swimming block and typically only slide forward and away from the front edge of the starting block to shorten the distance between the front edge of the starting block and the back plate.
Therefore, there is a need for a starting block having an adjustable back plate that is capable of being positioned in such a way so as to not interfere with the swimmer when the swimmer is mounting the starting block. There is also a need for an adjustable back plate that is able to accommodate swimmers who push off the starting block with either foot. There is a further need to provide a starting block system that can be easily retrofitted onto existing starting block systems that do not currently have a back plate.
The invention relates generally to a starting block system for a swimming pool, and more specifically to a starting block system having an adjustable back plate having a width that is less than that of the platform. The adjustable back plate reduces the time, effort, and expense necessary to install and maintain starting block systems due to the flexibility of allowing the starting block to work with all types of swimmers, and/or be removed from the platform when not in use. The starting block system further allows a swimmer to easily mount the starting block without interference from the back plate and to position the back plate into a desired location.
Some embodiments of the invention provide a starting block system that includes a pedestal, a platform for holding a swimmer, and an adjustable plate assembly that includes a laterally slideable back plate.
Some other embodiments of the invention provide a starting block system for use with a swimming pool. A pedestal is designed to support a platform and a back plate is disposed along a rear edge of the platform. The back plate has a width dimension that is less than the width dimension of the platform. A slide mechanism is disposed adjacent the rear edge of the platform and is in communication with the back plate. The back plate is designed to slide laterally adjacent the rear edge of the platform.
Still further embodiments of the invention provide a kit for retrofitting a starting block system. The kit includes a slide mechanism having a housing with a slot extending laterally therethough. A back plate support includes a back plate and a slide plate. The kit further includes a plate for locking the slide mechanism to a platform. The slide plate is designed to be disposed within the slot of the housing.

The platform 102 further includes a coating 270 that may be similar to the coating 234 associated with the back plate 134. The coating 270 is designed to impart a gripping surface to the platform via raised surfaces 272 and corresponding channels 274. The coating 270 may be imparted to one or more portions of the front surface 254 and comprises any material that provides the desired gripping and draining properties.
As shown in
The size of the platform 102 with respect to the size of the back plate 134 is proportioned to allow a swimmer to easily mount the platform 102 without substantial interference from the back plate 134. The swimmer can slide the back plate 134 to one side of the platform 102, or remove the back plate 134 all together when mounting the platform 102. As compared to some prior art systems, which include back plates 134 that extend along substantially the entire width of the platforms 102, the back plate 134 disclosed herein is designed to extend only a portion of the width of the platform 102. In one embodiment, the width WB of the back plate 134 is less than half of the width Wp of the platform 102. In a further embodiment, the width WB of the back plate 134 is about a third of the width Wp of the platform 102. In another embodiment, the width WB of the back plate 134 is less than third the width Wp of the platform 102. In a further embodiment, the width WB of the back plate 134 is about a fifth of the width WP of the platform 102.
The surface area provided to the front surface platform 102 as compared to the surface area of the back plate 134 are each proportioned to provide stability and flexibility to the starting block system 100. In one embodiment, the surface area of the front surface 224 of the back plate 134 is between about ¼th to about ⅙th of the surface area of the front surface 254 of the platform 102. In another embodiment, the surface area of the front surface 224 of the back plate 134 is about ⅕th of the surface area of the front surface 254 of the platform 102.
In some embodiments, it is envisioned that one or more components of the starting block system 100 may be retrofitted to an existing starting block that does not include an adjustable plate assembly 104. In these systems, the adjustable plate assembly 104 may be provided separate from the starting block system 100 and attached thereto. To attach the adjustable plate assembly 104 to the pedestal 106, the L-shaped brackets 152 are positioned adjacent the pedestal 106 such that the angled section 114 of the main support member 108 is within the gap 160 (see
An additional aspect of the starting block system 100 is the lateral adjustability of the back plate 134 as compared to the platform 102. The slide plate 190 is disposed within the slot 174 formed in the rear surface 144 of the slide mechanism 130. As shown in
In this way, the back plate 134 may be positioned in a desired location. For example, a right foot dominant swimmer may position the back plate 134 in the first position to allow the swimmer's right foot to be disposed on the back plate 134 when the swimmer is disposed on the starting block system 100. Similarly, a left foot dominant swimmer may position the back plate 134 in the second position to allow the swimmer's left foot to be disposed on the back plate 134 when the swimmer is disposed on the starting block system 100. An additional advantage is realized when the back plate 134 is able to be moved laterally when the swimmer is mounting the starting block system 100. In contrast to the prior art starting block systems, the width of the back plate 134 is smaller than the width of the platform 102, which allows the swimmer to move the back plate 134 and step onto the platform 102 from a rear position as opposed to the swimmer having to mount the starting block system 100 from the side (i.e., adjacent the hand grips 116).
In some instances, a locking mechanism (not shown) may be included to assist in retaining the back plate 134 in a specific position. In other embodiments, the back plate 134 is held into position via friction when a swimmer's foot contacts the back plate 134 prior to jumping.
