DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention is an improved bicycle rack for parking numerous bicycles, with tires of various widths, in the transition area of multisport races. The folding bicycle rack breaks down for easy transport and storage.

[0024] FIG. 2 is a side-perspective view of the folding bicycle rack 2 according to a first embodiment of the present invention, which generally comprises a plurality at tire trays 20 evenly spaced and pivotally mounted to a central rail 10. The tire trays 20 pivot away from, and towards, rail 10 from a parallel position relative to rail 10, to a perpendicular deployed position. The central rail 10 may be any length as a matter of design choice and may contain any number of tire trays 20. However, in a preferred embodiment an equal number of tire trays 20 are uniformly-spaced along each side of central rail 10. In the illustrated embodiment four tire trays 20 are pivotally mounted on each of the opposing sides of central rail 10 for a total of eight.

[0025] FIG. 3 is a top view of the rack 2 in a deployed position and FIG. 4 in a folded position, with exemplary dimensions shown.

[0026] When deployed, as shown in FIG. 3, each tire tray 20 projects perpendicularly outward from central rail 10, each seating one bicycle wheel (front or back) in an intermediate space 27. As illustrated, a first group of tire trays 20 pivots from the left side of central rail 10, and a second group of tire trays 20 pivots from the right side. Along each side the tire trays 20 are equidistant from each other at a distance N of approximately 20″. The first group is offset along central rail 10 such that a topmost tray 20 is a fraction N/2+M from the end of central rail 10, where M is an interger between 0 and N. The bottommost tray 20 is a fraction N/2−M from the opposing end of central rail 10. Thus, in the illustrated embodiment the central rail 10 is 1″ wide and 96″ long, and each tire tray 20 protrudes 24″ outward. The spacing N equals 20″, and M equals 6 such that topmost tray 20 is 16″ from the end of central rail 10, and the bottommost tray 20 is 4″ from the opposing end of central rail 10. This configuration of tire trays 20 maintains standing stability of the bicycles and effectively spaces the bicycles N=20″ apart when deployed to prevent entanglement, and provides just enough spacing so that each tire trays 20 folds neatly into the intra-tray space. Moreover, as will be described, the width of each intermediate space 27 may be adjusted for narrow or wide tires.

[0027] Pivoting each tire tray 20 to its parallel stowed configuration (FIG. 4 minimizes bulk and facilitates storage and transport of many such racks 2 to and from the transition area.

[0028] FIG. 5 is a top view of the tire tray 20 of FIGS. 2-4. Each tire tray 20 comprises an elongate trough-shaped member defined by an open-topped bed along its length. The ends of the bed are bordered by upright brackets 23, 24 both having a series of inwardly facing vertical open-ended channels 25. Upright brackets 23, 24 may be formed in this configuration by extruding aluminum. The sides of the bed are bordered by two rectangular panels 26A, 26B that slide within two vertical open-ended channels 25 on opposing sides of each tire tray 20. The panels 26A, 26B have distal flanges that slide into any one of channels 25 on each end of the tire tray 20. The panels 26A, 26B define atn intermediate space 27 for seating and constraining the bicycle wheel. Moving the panels 26A, 26B into different channels 25 changes the distance between the panels 26A, 26B and the width of intermediate space 27, thereby making it possible for the tire tray 20 to accommodate bicycles with tires of various widths. In addition, the flanges are offset to one side of each panel 26A, 26B such that inverting each panel 26A, 26B results in a slightly different width of intermediate space 27. The channels 25 (here four) on each side in combination with the invertible panels 26A, 26B yields several different widths of intermediate space 27, which is sufficient to conform to and seat all traditional bicycle tire widths ranging from 1″ to 3.25″. The bottom of the bed is defined by an elongate strut 28 running end to end between the upright brackets 23, 24 and secured there beneath by screws or weldment to the upright brackets 23, 24. In addition, a plurality (e.g., three) rectangular feet 29A-C are secured cross-wise to strut 28, at each end and to the center of the strut 28, by screws or weldment to provide ground support and constraint for each panel 26A, 26B within its selected channel 25. The skeletal configuration of strut 28 with feet 29A-C minimizes bulk and weight.

[0029] Note that the outer edges of brackets 23, 24 are defined by small channels 30 designed to hold printed signs 32 (see FIG. 2) cross-wise extending side-to-side between adjacent tire trays 20 when the bicycle rack 2 is in its deployed configuration (see also, FIGS. 2-3). In addition, the outermost channels 25 in each upright bracket 23, 24 may likewise be used to hold printed signs 32 extending along each tire tray 20 on both sides. Signs 32 are preferably rectangular cutouts of corrugated plastic imprinted with the user's name and/or a motivational message or the like. In addition to their signage value, signs 32 provide a convenient reinforcement for temporally locking the tire trays 20 in their deployed positions as seen in FIG. 3.

[0030] FIG. 6 is a side cross section of the rack 2 of FIGS. 2-4.

[0031] In each case the tire tray 20 is pivotally mounted to the central rail 10 at an offset pivot point, and in a manner that limits the pivotal arc of the tire tray 20 and prevents over-pivoting beyond perpendicular. This configuration constrains the tire trays 20 to movement between stowed and deployed positions and indexes the deployed position. In the illustrated embodiment, this is achieved by securing a pivot bracket 34 to the central rail 10. The pivot bracket is a flat strut preferably secured by screws or weldment beneath the central rail 10 and extending a short distance (e.g., perpendicularly outward to the tire tray 20 pivot point. The pivot bracket 34 is pivotally mounted to an angle bracket 35 that is secured to the inner upright bracket 23. As shown, the angle bracket 35 is preferably seated flush within a groove in upright bracket 23 and is fixedly attached thereto, and angles atop the pivot bracket 34. A lower reinforcement plate 36 sandwiches the pivot bracket 34, and the angle bracket and reinforcement plate 36 are held together by a double-headed pivot pin 7 that allows the entire tire tray 20 to pivot on pivot bracket 34. As seen in FIG. 5, one inner edge of the pivot bracket 34 is rounded and one is not, thereby allowing the tire tray to pivot in one direction only (toward the rounded edge), and indexing the perpendicular deployed position when pivot bracket 34 abuts angle bracket 35. This allows quick and easy setup and breakdown, minimizes bulk when carrying, and facilitates storage and transport of many such racks 2 to and from the transition area.

[0032] Moreover, the offset spacing of the topmost tray 20 front the end of central rail 10, versus the bottommost tray 20 from the opposing end of central rail 10 allows multiple bicycle racks 2 to be placed end-to-end to accommodate as many riders as desired. For this purpose, if desired, the central rails 10 may be provided with interlocking joints or collars (not shown) to secure them together.

[0033] It should now be apparent that the bicycle rack 2 described above is compact, modular, and stable. The rack 2 breaks down for easy transport and storage, and facilitates both the rapid setup and breakdown of an orderly temporary parking area for a large number of bicycles.

[0034] The bicycle rack 2 provides a separate space to park each bicycle, adjusts to bicycles with tires of various widths, and displays printed signs.

[0035] Moreover, any number of racks 2 can be joined side-by-side and end-to-end to park any desired number of bicycles temporarily.

[0036] Having now fully set forth the preferred embodiment and certain modifications of the concept underlying the present invention, various other embodiments as well as certain variations and modifications of the embodiments herein shown and described will obviously occur to those skilled in the art upon becoming familiar with said underlying concept. It is to be understood, therefore, that the invention may be practiced otherwise than as specifically set forth in the appended claims.
