FIELD OF INVENTION

[0001] The present invention relates to bicycle racks and more particularly to rear- mounted bicycle racks for carrying one or more passengers and/or cargo.

BACKGROUND

[0002] Bicycles have long been considered as one of the most convenient means of transportation for transporting riders and other articles from one place to another. Bicycle riding has also long been regarded as a popular recreational activity and exercise. Typically, bicycles are used for enjoying local activities, such as, going to a store for shopping, commuting to work, going out to a beach or mall with family and friends, going for a recreational ride at a park, and etc.

[0003] Often, bicycle riders are carrying articles or cargoes which are normally hand- carried items. These articles or cargoes interfere with the ability of the rider to safely maneuver and control the bicycle. In order to prevent the danger of an accident or the inconvenience of riding bicycles with such items, many devices have been introduced that can be attached to the bicycle for securely holding items such as grocery bags, books, or any other hand-carried items. These devices typically mount over the rear wheel of the bicycle or to the bicycle seat. For example, U.S. Patent No. 4,258,870, U.S. Patent No. 4,364,497, U.S. Patent No. 4,928,863, U.S. Patent No. 5,350,093, U.S. Patent No. 6,843,396, U.S. Patent No. 8,453,895 and U.S. Patent No. 8,857,686 disclose such devices. [0004] Moreover, many adult riders may wish to ride their bicycles with their loved one, child, pet, friend, etc. To this end, many passenger seat devices have been introduced, which are also usually mounted over the rear wheel for accommodating a toddler, child or small adult as a passenger. These passenger seat devices allow a bicycle rider to conveniently maneuver the bicycle and also safely carry a passenger while riding. For example, U.S. Patent No. 4, 141,587, U.S. Patent No. 4,964,551, U.S. Patent No. 5,884,920, U.S. Patent No. 7,331,629, U.S. Patent No. 8,251,388 and U.S. Patent No. 9,499,229 teach such devices.

[0005] Unfortunately, mounting a device for holding cargoes or mounting passenger seat device to a bicycle often demands considerable amount of time and effort. More

importantly, for most bicycles, one auxiliary device that is mounted must be removed from the bicycle before mounting another auxiliary device. Still further, because such auxiliary devices are often purchased from different manufacturers, different tools may be required for assembly. Other times, compatibility and interchangeability of the cargo holding device and the passenger seat device on a single bicycle may also generate problems in quickly mounting and removing these auxiliary devices.

SUMMARY OF THE INVENTION

[0006] It is an objective of the present invention to provide a rear-mounted bicycle rack system that includes a main frame which attaches over a rear wheel of a bicycle and allows for interchangeably mounting various auxiliary devices. It is a further objective of the present invention to provide a rear-mounted bicycle rack system that can interchangeably accommodate a large cargo deck, a small cargo deck, one or more passenger seats, or a small cargo deck with one passenger seat. [0007] These objectives and advantages are obtained by a bicycle rack system comprising a main frame configured to be mounted over a rear wheel of a bicycle. The main frame comprises a top platform for accommodating one or more first auxiliary devices, the top platform having a first platform section and a second platform section, at least one of the first and second platform sections configured to accommodate the first auxiliary device and a lower deck for accommodating one or more second auxiliary devices, the lower deck having a first deck section and a second deck section, at least one of the first and second deck sections configured to accommodate the second auxiliary device.

[0008] Other objectives, features and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings.

[0052] This description may use the phrases "in an embodiment," "in embodiments," "in some embodiments," or "in an alternative embodiment," which may each refer to one or more of the same or different embodiments in accordance with the present disclosure. It is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms.

[0053] In addition, numerous specific details are set forth in order to provide a thorough understanding of the implementations described herein. However, it will be understood by those of ordinary skill in the art that the implementations described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant function being described.

[0054] The present invention, in accordance with various embodiments and variations as described below, provides a bicycle rack system that can easily be mounted over a rear wheel of a bicycle of any size. A main frame of the rack system is designed to accommodate various auxiliary devices (e.g., a passenger seat or a saddle bag) at once. Processes for installation and uninstallation of any of these auxiliary devices are made extremely simple in order to drastically reduce the amount of time and effort needed. Furthermore, in accordance with the present invention, the bicycle rack system advantageously provides alternative means for carrying two passengers on the rear of a bicycle, one passenger and a cargo, or simply a large cargo, in a remarkably secure manner.

[0055] Referring now to the drawings, various embodiments for a bicycle rack system installed over a rear wheel of a bicycle is shown generally in FIGS. 1, 4-5, 7, 9, 11, 13, 15-16, 18, 21-35, 37 and 39-41. In each embodiment, the bicycle rack system comprises a main frame that is mounted over the rear wheel.

[0056] FIG. 1 shows a schematic illustration of an exemplary main frame 1 in accordance with an embodiment of the present invention. The main frame 1 is comprised of a top platform 1 A, vertical support bars IB, foot support bars 1C, tongues ID and axle-bracket holes IE. As shown in FIG. 1, the top platform 1 A is divided into a first section (toward a front end) and a second section (toward a rear end). As will be illustrated and discussed later in more detail, the top platform 1 A of the main frame 1 can accommodate one or more auxiliary mounting devices (e.g., a passenger seat, cargo board, saddle bag, etc.), one in the first section and another in the second section. Also shown in FIG. 1 are the foot support bars 1C provided on respective sides of the main frame 1. As will be illustrated and discussed later in more detail, the respective foot support bars 1C can each accommodate a foot deck. Also shown in FIG. 1 are the tongues ID at the front end of the top platform 1 A. As will be illustrated and discussed later in more detail, the tongues engage with a seat post bracket and secure the main frame 1 to a seat post of a bicycle. Finally, shown in FIG. 1 are the axle-bracket holes IE provided at or near the bottom of the vertical support bars IB and preferably even below the foot support bars 1C. As will be illustrated and discussed later in more detail, the axle-bracket holes IE align with a hub on a rear wheel of a bicycle and secure the main frame 1 to the rear wheel of the bicycle.

[0057] The exemplary main frame 1 and the components of the main frame 1 as shown in FIG. 1 are not intended to be limiting the scope of the invention in any way. The structure of the main frame, such as the size of the main frame itself or the relative length, width or thickness, and number of the components of the main frame may vary in order to

accommodate for different sizes of rear wheels of various bicycle designs, and/or to provide additional stability, control or balance based on weight of other parts of the bicycle and/or of one or more passengers. The main frame, as well as its components, may be made of any suitable metals (e.g., steel, aluminum, etc.), carbon fiber, or hardwood, but are not limited to such materials. In alternative embodiments, a main frame may employ fewer or more components without departing from the scope of the present invention.

[0058] FIG. 2 shows a schematic illustration of a seat post bracket in accordance with an embodiment of the present invention. The seat post bracket is comprised of a back portion 3 and a front portion 4. The back portion 3 of the seat post bracket comprises a series of holes and at least one or more of these holes align with a corresponding set of holes in the tongues ID of the main frame 1. Once the holes are aligned, the back portion 3 of the seat post bracket engages with the tongues ID of the main frame 1 via a series of connectors 18 that protrude through the holes. The connectors 18 as shown in FIG. 2 are a set of nuts and bolts but the invention is not limited to such devices, and other similar engagement devices or tools may be used to secure the seat post bracket to the main frame 1.

[0059] The front portion 4 of the seat post bracket is a separate piece that is used to secure the seat post bracket to a seat post of a bicycle (see FIGS. 40-41). The front portion 4 of the seat post bracket also includes a set of holes (e.g., one at each end) and these holes also align with a set of corresponding holes in the back portion 3 of the seat post bracket. The front portion 4, together with the back portion 3, engulfs a seat post of a bicycle (see FIGS. 40-41) and is tightened via a set of connectors 18 which protrude through the aligned holes.

[0060] FIG. 3 A shows a schematic illustration of a single-end axle bracket 2A and FIG. 3B shows schematic illustration of a double-end axle bracket 2B. The single-end axle brackets 2A have a hole at one end and an open end at an opposing end. The holes align with the axle-bracket holes IE of the main frame 1 and the connectors 18 are used to lock the axle brackets to the main frame 1. The open ends of the single-end axle brackets then engage with a hub on a rear wheel of a bicycle (not shown). The connectors 18 may also be used to secure the axle brackets 2 A and the main frame 1 to the hub. Unlike the single-end axle brackets 2 A, the double-end axle brackets 2B have holes at both ends but engage with the hub in a similar manner. FIGS. 4 and 5 respectively shows an embodiment in which the main frame 1 has assembled thereto, the seat post bracket and the single-end axle brackets 2A and an embodiment in which the main frame 1 has assembled thereto, the seat post bracket and the double-end axle brackets 2B. [0061] FIG. 6 shows a schematic illustration of a foot deck 5 in accordance with an embodiment of the present invention. The foot deck 5 comprises thereon a set of holes, one or more of which may be aligned with a set of corresponding holes on the foot support bars 1C of the main frame 1. The foot deck 5 is secured on the foot support bars 1C via the connectors 18. In a preferred embodiment, the size of the foot deck is long enough to accommodate two foot guards (to be discussed later with respect to FIGS. 19 and 20). In alternative embodiments, the foot deck may only extend for the length of the foot support bars 1C. FIG. 7 shows a schematic illustration of the main frame 1 having assembled thereon a pair of foot decks 5 via the connectors 18.

[0062] FIG. 8 shows a schematic illustration of a large cargo deck 6 in accordance with an embodiment of the present invention. The large cargo deck 6 extends substantially the length of the top platform 1A of the main frame 1. In alternative embodiments, the large cargo deck may extend beyond the length of the top platform. The large cargo deck 6 also comprises a series of holes, one or more of which align with holes provided on the top platform 1A. The large cargo deck 6 is secured to the main frame 1 via the one or more connectors 18. FIG. 9 shows a schematic illustration of the main frame 1 having assembled thereon the large cargo deck 6 on top of the top platform 1 A using the connectors 18.

[0063] FIG. 10 shows a schematic illustration of a small cargo deck 7 in accordance with an embodiment of the present invention. The small cargo deck 7 is similar in structure with the large cargo deck 6, except that the small cargo deck 6 only extends for the length of one of the first and second sections of the top platform 1 A. For example, the small cargo deck 7 may be positioned at the first section of the top platform 1 A allowing another small cargo deck 7, or a different auxiliary device (e.g., a passenger seat or a saddle bag), to be positioned at the second section of the top platform 1 A, or vice-versa. The small cargo deck 6 is also fastened to the top platform 1 A of the main frame 1 via the connectors 18. FIG. 11 shows a schematic illustration of the main frame 1 having assembled thereon the small cargo deck 7 at the second position of the top platform 1A using the connectors 18.

[0064] FIG. 12 shows a schematic illustration of a passenger seat 8 in accordance with an embodiment of the present invention. The passenger seat 8 may comprise one or more of a cloth strap 24, a 4-point harness 25, a seat pad 26 and a back pad 27. The size of the passenger seat 8 is such that it fits within one of the first and second section of the top platform 1 A. The passenger seat 8 is also fastened to the top platform 1 A via the connectors 18. FIG. 13 shows a schematic illustration of the main frame 1 having assembled thereon the passenger seat 8 at the first position of the top platform 1A using the connectors 18. As will be illustrated in subsequent embodiments, the invention is not limited to the small cargo deck 7 being positioned at the second section and the passenger seat 8 being positioned at the first section of the top platform 1 A. For a variety of purposes (e.g., convenience, safety, etc.) the passenger seat 8 may be positioned at the second section with or without the small cargo deck 7 being positioned at the first section of the top platform 1 A. In other embodiments, the main frame 1 may accommodate the large cargo deck 6 and the passenger seat may be installed on top of the large cargo deck 6.

[0065] FIG. 14 shows a schematic illustration of a saddle bag 10 in accordance with an embodiment of the present invention. The saddle bag 10 is designed to be placed over the small cargo deck 7, the large cargo deck 6, or the top platform 1 A of the main frame without the small cargo deck 7 or the large cargo deck 6. The center portion of the saddle bag 10 is a flat surface having an area that substantially matches the size of the first or section of the top platform 1 A. The center portion of the saddle bag 10 comprises a series of metal rings 17 and the saddle bag is secured to the small cargo deck 7 or to the top platform 1 A using the connectors 18 which protrude through the metal rings 17. The saddle bag further comprises two bagging portions, one on each side of the center portion. The two bagging portions provides a volume of space defined by the height of the main frame 1 and the width of the foot deck 5. Optionally, the two bagging portions are secured to the surface of respective foot decks via loop and hook strips 29. In alternative embodiments, the bagging portions may further comprise holes at the bottom allowing the connectors 18 to secure the bagging portions to the respective foot decks. The open top of the bagging portions of the saddle bag 10 may be partially or fully closed using cords 15 and cord stops 16. FIG. 15 shows a schematic illustration of the main frame 1 having assembled thereon the saddle bag 10 at the second position of the top platform 1 A using the connectors 18 and FIG. 16 shows a schematic illustration of the main frame 1 having assembled thereon the saddle bag 10 at the second position of the top platform 1 A and the passenger seat 8 at the first position of the top platform 1A. As mentioned earlier, the relative position of the saddle bag 10 and the passenger seat 8 on the top platform 1 A may be interchanged.

[0066] In accordance with the embodiments of the present invention, providing a saddle bag that includes bagging portions defined by the size of the main frame and secured to the foot decks provides an advantage of maximizing capacity and stability for articles to be carried while riding a bicycle. For example, the saddle bag 10 remains firm and fixed to the main frame 1, along with any articles contained therein, throughout any abrupt maneuver due to the loop and hook strips 29 or the connectors 18 preventing wobbling of the saddle bag 10.

[0067] FIG. 17 shows a schematic illustration of a T-Handle 9 in accordance with an embodiment of the present invention. The T-Handle 9 comprises a pair of cushion grips 28 and is attached to the back portion 3 of the seat post bracket. FIG. 18 shows a schematic illustration of the main frame 1 having attached thereto the T-Handle 9 on the back portion 3 of the seat post bracket. As shown in FIG. 18, the T-Handle 9 is intended for the passenger who sits in the passenger seat 8 positioned at the first section of the top platform 1 A. In an alternative embodiment in which the passenger seat 8 is positioned at the second section of the top platform 1 A, the length of the T-Handle 9 may extend from the seat post bracket to the passenger who sits at the second section of the top platform 1 A.

[0068] FIGS. 19 and 20 show schematic illustrations of foot guards in accordance with an embodiment of the present invention. In particular, FIG. 19 shows a pair of single foot guards 12A and 12B which provides front and side coverage for a passenger's feet. FIG. 20 shows a pair of double foot guards 13 A and 13B which provides front, side and top coverage for the passenger's feet. The size for either the single or double foot guards may vary to

accommodate the passenger's feet, but in a preferred embodiment, an individual foot guard is small enough such that two of such foot guards may rest on a single foot deck. In alternative embodiments, the size of the foot deck may be varied to accommodate the size of the foot guards. The single foot guards 12A and 12B or the double foot guards 13A and 13B are secured to the respective foot decks 5 via the connectors 18. FIGS. 21 and 22 show schematic illustrations of the main frame 1 having attached thereto, the single foot guards 12A and 12B or the double foot guards 13A and 13B.

[0069] In the foregoing embodiments, which may collectively be referred to as "a first embodiment" of the present invention, the bicycle rack system comprises, for example, a main frame 1, a pair of foot decks 5, a small cargo deck 7, a passenger seat 8, a T-Handle 9, a saddle bag 10 and a pair of foot guards (12 or 13), all of which are assembled using the same set of connectors 18. By configuring a bicycle rack system in which all of its constituents can be assembled (or disassembled) using a uniform set of tools (i.e., the connectors 18), the time and effort needed to assemble such system have been drastically reduced. Moreover, an apparent advantage of the first embodiment of the present invention is the usage of a single main frame which supports auxiliary devices for carrying both articles and a passenger in a firm and secure manner.

[0070] FIGS. 23-28 illustrate a second embodiment of a bicycle rack system in accordance with the present invention. The main frame 1 of the second embodiment utilizes the same elements as discussed above with respect to the first embodiment of the present invention. The second embodiment differs from the first embodiment in that the passenger seat 8 is positioned at the second section of the top platform 1 A. One of the advantages of this configuration is providing more leg room for the passenger. FIGS. 27 and 28 show schematic illustrations of the fully assembled bicycle rack system in accordance with the second embodiment of the present invention.

[0071] FIGS. 29-35 illustrate a third embodiment of a bicycle rack system in accordance with the present invention. The main frame 1 of the third embodiment utilizes the same elements as discussed above with respect to the first embodiment of the present invention. The third embodiment differs from the first or second embodiments in that two passenger seats 8 are installed on the top platform 1 A. The passenger seats 8, as discussed above, may be installed directly on the top platform 1 A, or on a cargo deck such as a large cargo deck 6 or respective small cargo decks 7. In this embodiment, a T-Handle 9 is provided only at the seat post bracket for the passenger riding in the passenger seat positioned at the first section. The passenger riding in the passenger seat positioned at the second section may grab onto the passenger seat positioned at the first section. Alternatively, another T-Handle 9 may be provided on the rear side of the passenger seat positioned at the first section. The second T-Handle may also be installed using the connectors 18.

[0072] In accordance with either the first, second or third embodiment, or in accordance with any variations of the foregoing embodiments, the bicycle rack system may further comprise a wheel cover or a frame cargo pack. FIG. 36 shows a schematic illustration of a wheel cover 11 in accordance with the present invention. The wheel cover left 11 A and the wheel cover right 1 IB, as shown in FIG. 36, each has a plurality of snap males and females which allow the wheel covers to be easily snapped onto the main frame 1. In alternative embodiments, the wheel covers may be attached to the main frame using similar adhesives (e.g., adhesive felt strips, dry adhesives, and etc.). The wheel covers can protect a passenger's feet from coming in contact with wheel spokes. FIG. 37 shows a schematic illustration of the main frame 1 having attached thereto, a pair of wheel covers 11 A and 1 IB. FIG. 37 shows the wheel covers being attached to the inner portions of the vertical support bars IB, but an alternative embodiment can have the wheel covers on the exterior portions of the vertical support bars IB.

[0073] FIG. 38 shows a schematic illustration of a cargo pack 14. The cargo pack 14 is generally attached to an underside of the top platform 1 A of the main frame 1 to provide additional storage area for articles. In accordance with the third embodiment of the present invention in which two passenger seats 8 are installed on the top platform, the cargo pack 14 can provide rooms below the passenger seats for storing items. The cargo pack 14 may be attached using hook and loop strips 29, or other similar techniques discussed above. The cargo pack 14 may be attached either in the first section or the second section of the top platform 1 A or there may be two cargo packs 14, one in each section, as long as the depth of the cargo pack 14 installed in the first section do not come in contact with the rear wheel of the bicycle. In some embodiments, the cargo pack below the first section may be smaller than the cargo pack below the second section.

[0074] FIG. 39 shows a schematic illustration of the main frame 1 having assembled thereon the cargo frame 14 underneath the second section of the top platform 1 A using hook and loop strips.

[0075] FIG. 40 shows an exemplary bicycle 30 having secured therewith the bicycle rack system in accordance with the present invention. As described herein, the main frame 1 of the bicycle rack system attaches to the bicycle 30 at two locations: 1) at the seat post, and 2) at the hub of the rear wheel. FIG. 41 is a close-up view on the rear of the bicycle 30 more clearly illustrating the connection of the main frame to the seat post and the rear wheel axle.

[0076] In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. It is understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangements of parts described and shown. Modifications can be made in the structure of the main frame without departing from the scope and purview of the invention as defined in the appended claims
