The field of the present disclosure relates generally to starting platforms for swimmers, and in particular, to such platforms incorporating an anchor ledge with an adjustment assembly for adjusting a position of the anchor ledge when desired.
Starting platforms for swimmers are well-known in the industry. For backstroke swimmers, various platform designs have been employed to provide anchor ledges for supporting a swimmer's feet and providing proper purchase as the swimmer prepares to push off prior to commencing the stroke. Many such conventional platforms provide a fixed anchor ledge that cannot be adjusted to suit a swimmer's needs. Accordingly, swimmers are not able to alter the position of the anchor ledge for their individual comfort. Other arrangements for adjustable anchor ledges include standalone systems designed to be supported by and removably affixable to the existing starting platform.
The present inventor has recognized various disadvantages of such standalone designs. For example, such anchor ledge systems are typically installed over the top surface of an existing starting platform where a swimmer would ordinarily stand when jumping into the pool. In some instances, such as during a medley race featuring multiple swimming disciplines, this conventional design requires the system to be installed prior to a backstroke swimmer beginning a race and thereafter removed for a subsequent swimmer to avoid creating potential tripping hazards or injuries for the swimmers. Another disadvantage is that by design, the system must be removed and reinstalled repeatedly on a starting platform, thereby increasing the likelihood of improper installation occurring at some point, which may lead to the ledge being unstable for the swimmer.
Accordingly, the present inventor has determined that it would be desirable to design a starting platform with an integrated adjustable backstroke anchor ledge that is secure and easy to use. In addition, the present inventor has determined that it would be desirable to have such a platform design that can be used for all swimming events without requiring removal of the anchor ledge system. Additional aspects and advantages of such a starting platform design will be apparent from the following detailed description of example embodiments, which proceed with reference to the accompanying drawings.
Understanding that the drawings depict only certain embodiments and are not, therefore, to be considered limiting in nature, these embodiments will be described and explained with additional specificity and detail with reference to the drawings.
With reference to the drawings, this section describes embodiments of a starting platform for swimmers and its detailed construction and operation. Throughout the specification, reference to “one embodiment,” “an embodiment,” or “some embodiments” means that a described feature, structure, or characteristic may be included in at least one embodiment of the starting platform being discussed. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” or “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the described features, structures, and characteristics may be combined in any suitable manner in one or more embodiments. In view of the disclosure herein, those skilled in the art will recognize that the various embodiments can be practiced without one or more of the specific details or with other methods, components, materials, or the like. In the following description, certain components of the starting platform are described in detail. It should be understood that in some instances, well-known structures, materials, or operations are not shown or not described in detail to avoid obscuring pertinent aspects of the embodiments.
Briefly, the anchor ledge assembly 110 includes a shaft assembly 116 (or shaft assembly 216) incorporated into the base 102 of the starting platform 100 within an interior cavity 126 thereof, the shaft assembly 116 (or shaft assembly 216) being actuatable via an adjustment mechanism 128 to adjust a position of the anchor ledge 112 for individual swimmers. The adjustment mechanism 128 is preferably positioned such that it is easily and comfortably reachable by a swimmer while in the water prior to commencing the backstroke. As illustrated in the figures, the anchor ledge assembly 110 is integrated into the base 102 of the starting platform 100. As such, the anchor ledge assembly 110 does not encumber other swimmers using the tread surface 104 for a standing start, thereby allowing the anchor ledge assembly 110 to remain coupled to the starting platform 100 at all times. With reference to the figures, the following provides additional details of these and other embodiments of the starting platform 100 and its components.
As illustrated in
Turning to
Briefly, the shaft assembly 216 includes an elongated, generally tubular shaft 218 disposed within the interior cavity 126 of the base 102, the shaft 218 extending horizontally across the base 102 of the starting platform 100 from the first side panel 138 to the second side panel 140 in a similar fashion as described previously with reference to shaft assembly 116. The shaft 218 extends through openings (not shown) formed on the side panels 138, 140 of the base 102. The shaft assembly 216 supports a compression spring 220 and supports the adjustment mechanisms 128, 130 for operation in a similar fashion as described previously with reference to the shaft assembly 116. The shaft assembly 216 includes a tube 222 (which avoids the need to use bellows 122) extending around the tubular shaft 218 and the compression spring 220, the tube 222 extending along the length of the shaft 218 between the side panels 138, 140. Additional details regarding operation of the shaft assembly 216 are provided below. As further described below with collective reference to
With particular reference to
With reference to
The engagement members 134 are sized and dimensioned to key the adjustment mechanism 128 to corresponding openings 136 formed along the first side panel 138 of the base 102 of the standing platform 100. In operation, the engagement members 134 and openings 136 cooperate with one another to facilitate gross adjustments of the position of the anchor ledge 112. As further described in detail below, the first adjustment mechanism 128 may be pulled away from the first side panel 138 and rotated to draw in the line 114, thereby adjusting the position of the anchor ledge 112. In some embodiments, the engagement members 134 and openings 136 may allow for vertical adjustments (either upwardly or downwardly) of the anchor ledge 112 in 20 millimeter increments. In such embodiments, the base 102 may accommodate a total travel of ±40 mm in either an upward direction (e.g., toward the tread surface 104 of the starting platform 100) or a downward direction (e.g., away from the tread surface 104 and toward the water surface). It should be understood that in other embodiments, the openings 136 may be formed at various height positions to accommodate adjustments at a larger or smaller scale than the example provided without departing from the principles of the disclosed subject matter.
With collective reference to
Once the first adjustment mechanism 128 has been pulled away from the side panel 138 to disengage the engagement members 134, the first adjustment mechanism 128 is rotated in either a clockwise or counterclockwise direction to affect a desired adjustment. In the example embodiment illustrated in the figures, the first adjustment mechanism 128 may be rotated in a counterclockwise direction to reposition the engagement members 134 adjacent to an adjoining opening 136 on the side panel 138. This counterclockwise rotation of the first adjustment mechanism 128 draws up a portion of the line 114 into the spool track 132, thereby shortening the overall length of the line 114 and moving the anchor ledge 112 upwardly toward the tread surface 104. Rotation of the first adjustment mechanism 128 urges rotation of both the shaft 118 (or the shaft 218) and the second adjustment mechanism 130, thereby evenly drawing up the line 114 and balancing the anchor ledge 112. Similarly, the first adjustment mechanism 128 may be rotated in a clockwise direction to reposition the engagement member 134 adjacent to a different opening 136. This clockwise rotation releases a portion of the line 114 from the spool track 132 to move the anchor ledge 112 downwardly away from the tread surface 104.
Once the desired position for the anchor ledge 112 has been determined for the swimmer, the first adjustment mechanism 128 is released. Upon release of the first adjustment mechanism 128, the compression spring 120 (or spring 220) of the shaft assembly 116 (or the shaft assembly 216) draws the engagement members 134 of the first adjustment mechanism 128 back against the side panel 138 to secure the engagement members 134 within the selected opening 136. Once the first adjustment mechanism 128 is secured against the side panel 138, the new height of the anchor ledge 112 is established. If further adjustments are necessary, the process may be repeated as needed until an appropriate final position for the anchor ledge 112 is found.
