Abstract
A seat rail for a bicycle seat and a method of fabricating same are disclosed. The seat rail comprises a rod having one or more flutes formed along the length of the rod. The seat rail provides support for a bicycle seat and provides means for securing the seat to the frame of a bicycle. The flutes in the rod reduce the effective cross-sectional area of the rod which results in a significant decrease in the weight of the seat rail, but without a significant loss of rigidity and strength. The fabrication method comprises providing an elongated rod-shaped feedstock, forming at least one flute along the length of the rod-shaped feedstock, and then bending the fluted feedstock to form the seat rail.
Description
- The present invention relates generally to a bicycle seat and in particular to a light-weight fluted bicycle seat rail.
- In the evolution of bicycle design a constant theme is the reduction of weight. Bicycle racers continually seek reductions in bicycle weight and recreational cyclists also desire lightweight bicycles for ease of handling and convenience. Consequently, decreasing the weight of a bicycle remains high among the important goals in bicycle design.
- While reduction in weight of the frame of the bicycle continues to be a major focus, weight reduction in other components of the bicycle can contribute to the goal of decreasing overall weight. For example, one component which has received little attention is the bicycle seat rail, which is used to support the seat and attach it to the frame. Current strategies used for weight reduction in components such as the frame are not well suited for reducing the weight of the seat rail due to the structural and functional differences between the seat rail and other bicycle components. The carbon or fiberglass reinforced resin tubes typically used for the frame or seat post are not well suited for use in a seat rail. The bicycle seat is usually clamped to hold it in place. Therefore, the seat rail is subject to point loading and potential gouging which might damage a non-metallic material and adversely affect the structural integrity of a seat rail formed of such a material. Consequently, a need exists for a new approach to weight reduction for the seat rail while maintaining sufficient strength and compatibility with current seat clamping systems.
- In response to these needs, the present invention provides a fluted bicycle seat rail. The seat rail comprises a rod having one or more flutes extending along at least a portion of the length of the rod. The seat rail provides support for a seat shell on which the rider sits and provides means for securing the shell in position relative to the frame of a bicycle. For example, the fluted rod of the seat rail can be formed as a curved member providing three contact points, an arcuate middle portion and two ends, to provide an armature for supporting the shell. The inclusion of flutes in the rod affords a decrease in the weight of the rod compared to a rod having a similar overall diameter but having no flutes. The present invention also provides a seat comprising the fluted seat rail. The seat comprises a shell and an armature in communication with the shell. The armature supports the shell and provides means to secure the shell relative to the frame of the bicycle. The armature comprises a fluted rod for supporting the shell.
- The present invention further provides a method for forming a fluted bicycle seat rail. The method comprises providing a rod-shaped feedstock, forming at least one flute along the length of the rod-shaped feedstock, and bending the fluted feedstock to form a seat rail.
- The foregoing summary and the following detailed description of the preferred embodiments of the present invention will be best understood when read in conjunction with the appended drawings, in which:
- FIG. 1 is a cross-sectional view of a preferred configuration for a seat rail of the present invention;
- FIG. 2 is a cross-sectional view of an alternate configuration for a seat rail of the present invention;
- FIG. 3 is a cross-sectional view of a further configuration for a seat rail of the present invention;
- FIG. 4 is a perspective view of an end portion of a seat rail of the present invention;
- FIG. 5 is a perspective, fragmentary view of a seat rail of the present invention attached to a seat post by a clamp;
- FIG. 6 is a perspective view of a seat rail of the present invention;
- FIG. 7 is a side elevational view of the seat rail of FIG. 6 when attached to a seat post by a clamp;
- FIG. 8 is a bottom view of a bicycle seat of the present invention; and
- FIG. 9 is a side elevational view of the bicycle seat of FIG. 8 when attached to a seat post.
- Referring now to the drawings, wherein like reference numerals refer to the same or similar components or features, and in particular to FIGS. 1 and 4, a
fluted rod 12 for use in a bicycle se at rail in accordance with the present invention is shown. Theelongated rod 12 has one ormore flutes 14 formed along at least a portion of the length of therod 12. Therod 12 preferably has a generallycircular cross-sectional shape 17 prior to the formation of theflutes 14 which is suited for clamping in standard seat post clamps. Alternatively, cross-sectional shapes other than circular, such as square or polygonal shapes, may be used. A particularly convenient cross-sectional shape which complies with current industry standards is a circular cross-sectional shape having a diameter of 0.276 inches. - The
flutes 14 are channels or grooves that extend along the length of therod 12 and haveflute surfaces 15 that are generally concave in shape. Theflute surfaces 15 may take the form of an arcuate surface or, alternatively, may have straight wall sections to form other shapes such as a V-groove or U-groove, for example. It may also be desirable to vary the shape and or depth of the flutes along a rod. The presence of theflutes 14 in therod 12 decreases the weight of therod 12 as compared to a similarly dimensioned rod without flutes. Theflutes 14 are preferably spaced at equal angular intervals about the circumference of therod 12. In the embodiment shown in FIG. 2 eachflute 24 is spaced about 120 degrees apart, and in the embodiment shown in FIG. 3, theflutes 34 are spaced approximately 90 degrees apart. Alternatively, theflutes - The angular spacing of the
flutes 14 is selected so that the spacing of thenon-fluted surfaces 13 of therod 12 are positioned to be gripped with the clamp used to attach the seat rail 10 to the bicycle frame. For example, as shown in FIG. 5, the seat rail 10 is attached to a seat post 40 using a clamp 42. The clamp 42 includes anupper clamping element 46 and a lower clamping element 44 each having grooves formed on the gripping surface thereof. Thenon-fluted surfaces 13 of therod 12 are oriented so that thenon-fluted surfaces 13 contact the grooves of theupper clamping element 46 and lower clamping element 44. This orientation of theflutes 14 andnon-fluted surfaces 13 is also selected to maximize the load-bearing capacity of therod 12. The load-bearing capacity of therod 12 is maximized when the rod is oriented in the clamp 42 with theflutes 14 not facing the gripping surfaces of the clamp 42. - FIGS.6-9 show perspective and plan views of a seat rail 10 for a bicycle seat. The seat rail 10 has an overall shape that is formed for supporting a
seat shell 48 to provide an armature for theseat shell 48. In particular, the seat rail 10 is preferably shaped to provide contact with theseat shell 48 at multiple points. For example, as best seen in FIGS. 6-8, the seat rail 10 includes acurved front portion 16, which is preferably located proximate the midpoint ofrod 12 between the ends 18 a, 18 b. Between thecurved front portion 16 and each of the ends 18 a, 18 b are twolinear portions 19 a, 19 b disposed in parallel, spaced-apart relation. The seat rail 10 is preferably configured so that thecurved front portion 16 and ends 18 a, 18 b are offset from thelinear portions 19 a, 19 b to permit contact between theseat shell 48 and thecurved front portion 16 and ends 18 a, 18 b. As shown in FIG. 8, each end 18 a, 18 b of the seat rail 10 engages with recesses in the rear of theseat shell 48, and in particular may be received by mounting holes 47 provided in theseat shell 48. A third point of contact between the seat rail 10 and theseat shell 48 is made between the front of theseat shell 48 and thecurved front portion 16. Thecurved front portion 16 engages with a cavity 49 formed in the front of theseat shell 48. Thelinear portions 19 a, 19 b are spaced away from theseat shell 48 to provide clamping portions whereby theseat shell 48 can be clamped to the seat post 40. - The
rod 12 is formed from a lightweight material having sufficient strength and rigidity to support theseat shell 48. Preferred materials are high strength, lightweight metals and metal alloys, including, but not limited to titanium, titanium alloys, aluminum, and aluminum alloys. A particularly preferred material is a titanium based alloy containing about 6 percent by weight aluminum and 4 percent by weight vanadium (Ti-6Al-4V). In addition to the strength and rigidity requirements, the material of therod 12 is selected to permit easy processing of the rod to form theflutes 14 and the overall shape of the seat rail 10 by methods such as those of the present invention. - A method for forming a fluted bicycle seat rail in accordance with the present invention includes the steps of providing a rod-shaped feedstock, forming at least one flute along the length of the rod-shaped feedstock, and bending the fluted feedstock to form the seat rail. Formation of the flute in the feedstock is accomplished by various processes, such as roll processing, die drawing, swaging, forging, machining, powder metallurgy, extrusion, or a combination thereof. Roll processing is a preferred technique for forming the flutes in a material such as the Ti-6Al-4V alloy.
- Roll processing to form the flutes includes the step of selecting an elongated feedstock having a cross-sectional dimension selected to yield a desired cross-sectional dimension after processing the feedstock to form the flutes therein. The characteristic dimension in the case of a circular rod, for example, would be the cross-sectional diameter. Roll processing also includes the step of providing a rolling mill fitted with an even number of rolls arranged in opposing pairs. Each roll has a roll surface for contacting the surface of the feedstock, with the shape of the roll surface selected to impart a complementary shape in the contacted surface of the feedstock. For forming a flute, the roll surface of at least one roll has a convex shape that is selected to provide the desired flute surface geometry. As the feedstock is compressed by such a roll, the feedstock is indented, thereby forming a flute along the length of the feedstock.
- By way of example, to yield the shape depicted in FIG. 1, a single pair of opposing rolls may be provided in a rolling mill, with each roll having a convex roll surface for indenting the feedstock. As the feedstock is processed through a rolling mill so configured, two
flutes 14 are formed on opposing sides of the feedstock to yield thefluted rod 12 depicted in FIG. 1. In addition, such a configured rolling mill may be used to produce afluted rod 32 having two pairs of opposing flutes, i.e., having a total of four flutes, as depicted in FIG. 3. In such a case, the feedstock may first be passed through the rolling mill to yield afluted rod 12 having twoflutes 14. Subsequently, thefluted rod 12 may be passed through the rolling mill a second time, with thefluted rod 12 inserted so that thenon-fluted surfaces 13 of thefluted rod 12 contact the rolls so that twoadditional flutes 34 are formed in thefluted rod 12 to yield thefluted rod 32 having four flutes. Alternatively, a fluted rod having four flutes may be formed in a single passed through a rolling mill having two pairs of rolls configured to form four flutes along the length of the feedstock. - In addition, the rolling mill can be configured so that one or more non-opposing flutes can be formed in a feedstock. An example of a fluted rod with non-opposing flutes is depicted in FIG. 2. To produce a fluted rod with non opposing flutes, the rolling mill may be configured with a pair of opposing rolls, where one of the rolls includes a convex surface for forming a flute in the feedstock and the other roll includes a roll surface shaped to provide a non-fluted surface in the feedstock. For example, with reference to the
fluted rod 22 shown in FIG. 2, a first roll may have a convex surface for forming theflute 24 and an opposing second roll may have a concave surface for forming or maintaining thenon-fluted surface 23. The rolling mill may be configured with three such pairs of rolls, each pair containing one roll with a concave surface and a second roll with a convex surface so that threeflutes 24 are formed in the feedstock upon a single pass through the rolling mill. Alternatively, the rolling mill may be configured with a single pair of rolls for forming asingle flute 24, and the feedstock may be passed through the rolling mill multiple times at different orientations for formingadditional flutes 24. - The roll processing is preferably performed in such a manner so that the material displaced by the compressing operation results in reduction of the cross-sectional area and elongation of the feedstock. The cross-sectional area may be compressed, for example, to yield an industry standard diameter, such as 0.276″ diameter. Such a reduced cross-sectional area will be less than that of the initial cross-sectional area of the feedstock. Hence after roll processing, a given length of the fluted rod will necessarily have a lower weight relative to an equivalent length of the feedstock from which the fluted rod was formed.
- Once the feedstock has been processed to create the fluted rod, the rod is cut to a desired length suitable for forming the seat rail. Alternatively, the feedstock may be cut to the desired length prior to the fluting step. To form the seat rail from the fluted rod, the fluted rod is bent to give the fluted rod the desired overall shape as an armature for supporting the seat shell. As an alternative to the bending process, the fluting process, or both, the seat rail may be formed by machining, casting processes, powder metallurgy, or extrusions, to provide the fluted seat rail armature.
- These and other advantages of the present invention will be apparent to those skilled in the art from the foregoing specification. Accordingly, it will be recognized by those skilled in the art that changes or modifications may be made to the above-described embodiments without departing from the broad inventive concepts of the invention. It should therefore be understood that this invention is not limited to the particular embodiments described herein, but is intended to include all changes and modifications that are within the scope and spirit of the invention as set forth in the claims.
