1. Field of the Invention
This invention generally relates to a rowing boat footrest assembly. More specifically, the present invention relates to rowing boat footrest assembly that includes a pivotable footrest member.
2. Background Information
Rowing is becoming an increasingly more popular form of recreation. Moreover, rowing has become a very popular competitive sport for both amateurs and professionals. Whether rowing is for recreation or competition, the rowing industry is constantly improving the various components of rowing boats and equipment used by rowing enthusiasts. One component that has been extensively redesigned is the rowing boat footrest.
Traditionally, the footrest in a rowboat is an angled surface upon which a rower can brace his or her feet to provide increased power during the rowing process. Recently, footrests have been provided with simple shoe retaining straps or mechanisms that hold a rower's shoe against the surface of the footrest. However, there is a problem with such structures in that the rowers shoe and foot are fixed in place and cannot move or pivot with the motion of the rower during the rowing back and forth stroke.
In view of the above, it will be apparent to those skilled in the art from this disclosure that there exists a need for an improved footrest configuration that allows for movement of a rower's foot relative to a footrest. This invention addresses this need in the art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
One object of the present invention is to provide a footrest assembly for a rowing boat with structure that allows the rower's foot to pivot during the rowing motions.
Another object of the present invention is to provide a footrest assembly that is easily adjusted to suit movements of a variety of rowers regardless of their size.
Still another object of the present invention is to provide a footrest assembly with structure that allows the feet of a rower to pivot about the thumb joint or ball of the foot.
The foregoing objects can basically be attained by providing a rowing boat footrest assembly with a stationary support member and a footrest member. Preferably, the stationary support member is configured and arranged for coupling to a boat structure with a pivot axis that extends through a portion of the stationary support member. The footrest member has a footrest surface coupled to the stationary support member for pivotal movement about the pivot axis. The footrest member is further configured and arranged to support a shoe such that with the shoe positioned on the footrest surface the pivot axis extends laterally through the shoe between a sole of the shoe and an upper surface of the shoe.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the present invention.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments of the present invention are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to
A portion of the rowing boat 10 is depicted in
The hull 14 can have any of a variety of conventional shapes and configurations depending upon whether the boat is a sweep-oar rowing boat or a sculling rowing boat. More specifically, the size and shape of the hull 14 can have any size and shape that can accommodate the footrest assembly 12. The support structure 16 is a conventional structure that is rigidly fixed to or rigidly supported to the interior of the hull 14 or gunwale portion of the hull 14. The support structure 16 includes a seat support portion 20 and a footrest assembly support portion 22.
It should be understood from the drawings and the description herein that the support structure 16 can be a single structure supported by and/or rigidly fixed to the hull 14, or alternatively can be two or more separated structures that are supported or rigidly fixed to the hull 14.
The seat support portion 20 includes parallel rails 20a disposed on either side of the hull 14 that support the seat 18. The seat 18 includes bearing portions such as rolling wheels or bushing surfaces that allow the seat 18 to slide smoothly fore and aft relative to the hull 14 along the parallel rails 20a.
The footrest assembly support portion 22 includes rails 22a and 22b. There are preferably two of the rails 22a arranged parallel to one another along the side of the hull 14. The rails 22a can be extensions of the parallel rails 20a or can be separate elements that extend in-line with or parallel to the parallel rails 20a. The rail 22b can be centered along the floor of the hull 14. In the depicted embodiment, the rail 22b is equidistant from the rails 22a, but is lower that the rails 22a.
When seated in the seat 18, a rower R can put his or her feet on the footrest assembly 12 and use the footrest assembly 12 as leverage to assist in rowing the rowing boat 10.
With specific reference to
The first lateral support member 30 extends laterally relative to the rowing boat 10 between sides of the hull 14. The first lateral support member 30 includes gripping blocks 50 that engage tracks 52 that are rigidly fixed on respective upper surfaces of the rails 22a of the footrest assembly support portion 22 of the support structure 16. The gripping blocks 50 and the tracks 52 include mating gear teeth configured such that the first lateral support member 30 can be selectively position along the rails 22a. For example, a taller rower may want the footrest assembly 12 moved to a forward position closer to the bow of the rowing boat 10. Shorter rower may want to move the footrest assembly 12 to a more rearward position toward the stern of the rowing boat 10.
Once positioned, the mating gear teeth of the gripping blocks 50 and the engage tracks 52 help to maintain the footrest assembly 12 in the selected position. Although not shown, the gripping blocks 50 can further include clamping elements or fasteners for selectively securing the gripping blocks 50 to the rails 22a once the footrest assembly 12 is positioned in the desired location.
The inclined support member 32 is a U-shaped member with two generally parallel portions that have upper ends 54. The upper ends 54 are fixedly attached to the first lateral support member 30 by clamping assemblies C1 (shown in
The inclined support member 32 further includes a pair of symmetrically arranged right and left side heel support members 64. Each of the heel support members 64 has an upper end 64a that is pivotally supported to the inclined support member 32, a shoe contacting surface 64b and an arcuate slot 64c with a fastener F extending therethrough into the inclined support member 32. The arcuate slot 64c and the fastener F are configured such that the position of the shoe contacting surface 64b can be adjusted with the heel support members 64 pivoting about a pivot point 64d. As is clear from
It should be understood from the drawings and the description herein that although the inclined support member 32 has a U-shape, alternative shapes and configurations can be used for the inclined support member 32. For example, the inclined support member 32 can have a V-shape, or can be a flat member welded to or otherwise extending from the first lateral support member 30. Alternatively, the first lateral support member 30 and the inclined support member 32 can be formed as a single unitary element that has an overall planar configuration.
The second lateral support member 34 extends in a generally horizontal direction between portions of the inclined support member 32. The second lateral support member 34 is adjustably fixed to the inclined support member 32 by clamps C2 shown in
It should be understood from the drawings and the description herein, that the second lateral support member 34 is not limited to the depicted shape or dimensions. Specifically, the second lateral support member 34 can be adjustably positioned along the inclined support member 32 any of a variety of shaped elements that accomplish the same adjustment features of the depicted embodiment. More specifically, the second lateral support member 34 is adjustable along the inclined length of the inclined support member 32 regardless of the size, shape and overall structure of the inclined support member 32. In an alternative embodiment, the second lateral support member 34 can be non-movably and rigidly fixed to the inclined support member 32 or can be formed as a part of the inclined support member 32.
The U-shaped footrest members 38 and the shoe attachment portions 40 are all generally the same except that they can be symmetrically configured such that there is one of each for a left shoe and one of each for a right shoe. For the sake of brevity, only one of each of the U-shaped footrest members 38 and the shoe attachment portions 40 is described, the description applying to both.
As seen in
The U-shaped footrest member 38 includes pivot support ends 71 and a footrest surface 72. The U-shaped footrest member 38 is U-shaped member with the pivot support ends 71 being spaced apart from the footrest surface 72 with the pivot axis A extending through the pivot support ends 71. Consequently, the U-shaped footrest member 38 undergoes pivotal movement about the pivot axis A.
The footrest surface 72 is configured and arranged to support a shoe S (FIGS. 1 and 3-5) such that with the shoe S positioned on the footrest surface 72, the pivot axis A extends laterally through the shoe S between a sole 74 of the shoe and an upper surface 76 of the shoe S, as shown in
The height of the footrest surface 72 is extended by the inclusion of the shoe attachment portion 40. The shoe attachment portion 40 can be a conventional shoe attachment mechanism such as is used on a bicycle. Specifically, the shoe attachment portion 40 can be a clipless type shoe pedal attachment mechanism, such as those disclosed in, for example, U.S. Pat. No. 6,925,908 and U.S. Pat. No. 6,119,551. In such a clipless type shoe attachment mechanism, the shoe S includes a cleat or attachment member (not shown) that is releasably retained by the shoe attachment portion 40 in a conventional manner.
With the shoe S retained by the shoe attachment portion 40, the pivot axis A extends through the shoe S at a location corresponding to a thumb joint portion of a foot of the rower R with the shoe S in a rowing position depicted in
Having the pivot axis A extend through the thumb joint of the foot of the rower R provides the rower R with an optimal rowing stance. Specifically, as the rower R moves through the rowing motion, the U-shaped footrest member 38 pivots about the pivot axis A in a motion that assists the rower R in optimizing exertion during rowing.
Corresponding to each of the U-shaped footrest members 38, the second lateral support member 34 (the stationary support member) further includes a first or upper side motion limiting portion 80 and a second or lower side motion limiting portion 82. The first motion limiting portion 80 is configured and arranged to limit pivoting movement of the footrest member on an upper side of the second lateral support member 34 when the footrest member is pivoted upwardly with respect to the third support member 36 (e.g., the stationary support member) from a center position. The second motion limiting portion 82 is configured and arranged to limit pivoting movement of the footrest member on a lower side of the second lateral support member 34 when the footrest member is pivoted downwardly with respect to the third support member 36 (e.g., the stationary support member) from the center position. The first and second motion limiting portions 80 and 82 include an adjustment section configured and arranged to adjust the overall angular pivoting movement of the U-shaped footrest member 38.
Specifically, by loosening the fastener F on the first motion limiting portion 80, the first motion limiting portion 80 can be adjustable to contact a portion of the U-shaped footrest member 38, as shown in
One function of the first motion limiting portion 80 is to provide a stationary structure to limit movement of the U-shaped footrest member 38 when the rower R steps into the U-shaped footrest member 38 making it easier for the shoe S to be secured to the shoe attachment portion 40.
The second motion limiting portion 82 is adjustable in a similar manner but with different criteria. Specifically, by loosening the fastener F on the second motion limiting portion 82, the rower R can adjust the position of the second motion limiting portion 82 such that counter-clockwise pivoting movement of the U-shaped footrest member 38 is stopped, as shown in
Specifically as shown in
Consequently, the first and second motion limiting portions 80 and 82, allow the rower R to adjust the overall pivoting motion of the shoe S. Such adjustments allow the rower R to limit movement of the shoe S to a specific angular range of movement.
The heel support members 64 also serve as movement stop portion dimensioned for contact with the heel H of the shoe S to limit pivoting movement of the shoe S relative to the pivot axis A with the shoe in a rowing position or orientation on the U-shaped footrest member 38, as shown in
More specifically, since the U-shaped footrest members 38 are pivotable about the axis A, the shoe S can move with the rower R during the rowing motion. For instance, as shown in
The U-shaped footrest assembly 12 can also easily modified for use in other sports related applications. Specifically, the support members 32, the U-shaped footrest members 34 and the shoe attachment portions 40 can be used on skates for speed skating, where a shoe portion of a skate assembly pivots relative to a blade. Such skates used in speed skating are also known as clapskates, slapskates or slap skates.
