This invention relates to a stand or rack for use in maintaining a bicycle or the like in an upright position, and more particularly to a parking stand or rack that is collapsible when not in use.
There are many known types of parking stands or racks that are designed to maintain a bicycle or the like in an upright position. Typically, a parking stand or rack includes a lower support area which engages a lower area of one of the bicycle wheels, and an upwardly extending section, which may be in the form of a pair of spaced apart bars that define a space configured to receive the bicycle wheel at a location above the lower support area. The bars engage the sides of the wheel, to maintain the bicycle in an upright position. This type of parking stand or rack is typically a self-supporting, stationary structure adapted to remain in a predetermined location, e.g. adjacent a building, park, train station, etc.
Smaller, compact parking stands or racks have been developed for residential and other uses where it is desired to park a relatively small number of bicycles, as well as for use in other bicycle parking applications, e.g. at the starting or finishing area of a bicycle race or in the staging area of a triathlon. The latter applications require a bicycle parking stand or rack that is capable of being transported in a vehicle and set up in any desired location on site. An example of such a rack or stand is illustrated in Martinell U.S. Pat. No. 5,133,461, which discloses a parking stand or rack constructed of modules that are pivotably interconnected together for movement between a folded position for storage and an unfolded position for use in parking bicycles. Each module includes a top tube, and the top tubes of adjacent modules are aligned so as to define a passage through which a tension member extends. The ends of the tension member are threaded, and nuts are engaged with the threaded ends of the tension member and with the ends of the aligned top tubes, to selectively maintain the modules in the unfolded position for use. The nuts are loosened so as to relieve tension in the tension member in order to allow the modules to be folded together for storage. While a rack as disclosed in the '461 patent is portable and collapsible so as to be capable of use in the noted applications, there are certain features of this type of rack that present disadvantages in construction and/or operation. For example, the tension member can be separated from the modules and lost or misplaced. In addition, the tension member and the nuts add to the overall number of parts that are incorporated into the rack. Further, the user can position the modules in different angular positions relative to each other, and the retention of the modules in the unfolded use position is controlled by engagement of the nuts with the ends of the top tubes of the modules. In the event the nuts are not sufficiently tightened against the top tube ends, the angular relationship of the modules may be subject to change if the rack is bumped or struck after the position of the modules has initially been set.
It is an object of the present invention to provide a portable, collapsible rack or stand for supporting bicycles or the like in an upright position, in which the components of the rack or stand are assembled together and cannot be removed, to ensure that the components cannot be lost or misplaced. It is a further object of the invention to provide such a rack or stand which provides a consistent position when the rack or stand is in the unfolded position for use. Another object of the invention is to provide such a rack or stand having a hinge arrangement for providing movement of the rack or stand between a folded condition and an unfolded condition, and including a stop arrangement that is independent of the hinge arrangement for providing consistent conditioning of the components of the rack or stand in the unfolded use position. Yet another object of the invention is to provide such a rack or stand that is relatively simple in its components, construction and operation, yet which provides consistent, reliable operation and is easy to fold for storage or transport.
In accordance with the present invention, a rack or stand for use in maintaining a bicycle or the like in an upright position, includes a pair of supports, at least one of which includes a pair of spaced apart members that define a space configured to receive a wheel of the bicycle or the like therebetween. Each support includes a lower support member and an upper member located above the lower support member. The pair of spaced apart members are interconnected with and extend between the upper and lower members.
The upper members of the pair of supports are pivotably interconnected together via a hinge arrangement that defines a pivot axis that is offset from a longitudinal axis defined by each of the upper members. In a representative embodiment, the hinge arrangement includes a hinge barrel secured to the exterior of a wall defined by each of the upper members, and a hinge pin that extends through aligned passages defined by the hinge barrels. The hinge pin defines the pivot axis about which the supports are pivotable for movement between an unfolded, open operative position for use and a closed, collapsed inoperative position for storage.
The hinge barrels are positioned relative to the upper members such that the pivot axis defined by the hinge pin is located below a center defined by each of the upper members. With this arrangement, pivoting movement of the supports from the closed, collapsed position toward the open, operative position results in engagement of facing areas of the upper members with each other at a location above the pivot axis. Such engagement of the upper members functions as a stop so as to place the supports in a predetermined angular orientation when the supports are moved apart. To collapse the rack or stand for transport or storage, the supports are pivoted toward each other about the pivot axis defined by the hinge pin. The supports are configured so as to assume a generally parallel orientation when in the closed, collapsed position, to minimize the space occupied by the stand or rack.
Various other features, objects and advantages of the invention will be made apparent from the following description taken together with the drawings.
The drawings illustrate the best mode presently contemplated of carrying out the invention.
In the drawings:
A parking rack or stand 10, for use in parking a bicycle or the like, includes a pair of supports 12a, 12b that are pivotably interconnected, in a manner to be explained, for movement between an open or unfolded, operative use position as shown in
Supports 12a, 12b include respective lower members 14a, 14b and respective upper members 16a, 16b. A pair of side members 18a extend between and interconnect lower member 14a and upper member 16a, and a pair of side members 18b extend between and interconnect lower member 14b and upper member 16b. In the illustrated embodiment, upper members 16a, 16b and respective side members 18a, 18b are formed of a single length of bent tubular material, the ends of which are secured to respective lower members 14a and 14b, such as by welding or in any other satisfactory manner. It is understood, however, that this construction is representative and that the upper member and the side members of each support may be formed of separate lengths of material that are joined together in any satisfactory manner.
Support 12a includes inner upright members, in the form of inner support bars 20a, each of which is spaced inwardly from one of side members 18a. Each inner support bar 20a defines a lower end secured to lower member 14a and an upper end secured to upper member 16a. Likewise, inner upright members in the form of inner support bars 20b are spaced inwardly from side members 18b, defining lower ends secured to lower member 14b and upper ends secured to upper member 16b. With this construction, each side member 18a and its associated inner support bar 20a cooperate to define a space 22a, which is closed at its lower end by lower member 14a and at its upper end by the transition area between side member 18a and upper member 16a. Likewise, each side member 18b and its associated inner support bar 20b cooperate to define a space 22b that is closed at its lower end by lower member 14b and at its upper end by the transition area between side member 18b and upper member 16b.
Lower member 14a defines end sections 24a and 26a, each of which is located outwardly of one of side members 18a. Similarly, lower member 14b defines end sections 24b and 26b, each of which is located outwardly of one of side members 18b. End section 24a has a length greater than that of end section 26a, and likewise end section 24b has a length greater than that of end section 26b. Supports 12a and 12b are connected together in a laterally offset fashion, such that the space 22a located adjacent end section 26a is in alignment with end section 24b of lower member 14b, and space 22b located adjacent end area 26b is in alignment with end section 24a of lower member 14a. In this manner, space 22a located adjacent end section 24a is in alignment with the area of lower member 14a between inner support bars 20b, and likewise space 22b adjacent end section 24b is in alignment with the area of lower member 14a located between inner support bars 20a.
Hinge barrel 32a is located below the center of upper member 16a, and likewise hinge barrel 32b is located below the center of upper member 16b. When supports 12a and 12b are positioned in a facing manner for connection together, hinge barrels 32a, 32b are located in an inside position between upper members 16a and 16b. Hinge barrels 32a, 32b are positioned such that facing surfaces of upper members 16a and 16b, shown at 38a and 38b, respectively, are moved into engagement with each other when supports 12a and 12b are pivoted outwardly about the pivot axis defined by hinge pin 36 away from the folded, inoperative position of
In operation, the user moves supports 12a and 12b apart, from the closed position of
To subsequently move the stand 10 to the closed or folded position for storage or transport, the user grasps any satisfactory area of stand 10 below upper members 16a and 16b, and pivots the supports 12a and 12b together to the position of
It can thus be appreciated that the present invention provides a relatively simple stand for use in supporting a bicycle or the like, which can be quickly and easily moved between its operative, open position for use and its inoperative, closed position for storage. The stand has a relatively small number of parts that are relatively easy to produce and assemble, to provide an economical cost of manufacture. In addition, the positioning of the hinge provides a unique stop feature by virtue of engagement of the upper members when the supports are unfolded, to provide consistent positioning of the supports without the need to incorporate a stop into the hinge arrangement itself.
While the invention has been described with respect to a particular embodiment, it is understood that alternatives and modifications are possible and are contemplated as being within the scope of the present invention. For example, and without limitation, while each of the supports is illustrated as having two spaces, each of which is adapted to receive a bicycle wheel, it is understood that each support may have a single space or may have any number of spaces greater than two, and that the length of each support may vary so as to accommodate the number of spaces incorporated in the support. In addition, while each support is illustrated as having side members and a top member that are formed of a single piece of material that is bent and connected at its ends to the bottom member, it is also understood that each support may have side members that are separate from the top member and that are connected between the top and bottom members. Further, while the spaces are shown as being defined by the side members in combination with support bars spaced inwardly from the side members, it is understood that the spaces may be defined by any other satisfactory structure that is carried by the support. In addition, while the facing surfaces of the top members are shown as engaging each other to limit outward movement of the supports to the open, operative position, it is also understood that the supports may be provided with any structure located above the hinge and separate from the hinge which is moved into engagement when the supports are opened so as to limit movement of the supports to the open, operative position. Preferably, any such structure is connected or mounted to the outside of the upper member wall. It is also contemplated that the stop structure which limits movement of the supports may be incorporated in the hinge itself, however, the illustrated construction in which the stop arrangement is separate from the hinge and is associated with the upper members of the supports provides a simplified, reliable and easily manufacturable stop arrangement. In addition, while the supports are shown and described as being identical in construction, it is also understood that the support on one side of the stand may have a different construction than the support on the other side of the stand. For example, the support on one side of the stand may have spaces to receive the bicycle wheels, whereas the support on the other side of the stand may simply function to brace the support with the spaces.
