DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new velocipede embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the foldable velocipede 10 generally comprises a bicycle 12 that comprises a frame 14. The frame 14 has a top tube 16 and a down tube 18. The top tube 16 and the down tube 18 each comprise a front section 20 and a rear section 22.
Each of a pair of rotators 24 is coupled to and extends between a respective front section 20 and an associated rear section 22. The rotators 24 are positioned in the top tube 16 and the down tube 18 such that the top tube 16 and the down tube 18 are selectively positionable in extended configurations. In the extended configuration, each front section 20 extends linearly from an associated rear section 22 and the bicycle 12 is configured for riding. The top tube 16 and the down tube 18 also are selectively positionable in folded configurations. In the folded configuration, each front section 20 is positioned substantially adjacent to an associated rear section 22 and the bicycle 12 is configured for stowage. The pair of rotators 24 is substantially vertically aligned within said frame 14.
In one embodiment, each rotator 24 comprises a first rod 26, a second rod 28 and a plurality of hinges 30. The first rod 26 is coupled to and is positioned in the rear section 22. The second rod 28 is coupled to and is positioned in the front section 20. The hinges 30 are linearly coupled. The plurality of hinges 30 is coupled to and extends between the first rod 26 and the second rod 28. In another embodiment, the first rod 26 is threadedly coupled to the rear section 22 and the second rod 28 is threadedly coupled to the front section 20. In yet another embodiment, the plurality of hinges 30 comprises a first hinge 32, which is coupled to the first rod 26, and a second hinge 34, which is coupled to the second rod 28.
In one embodiment, a third rod 36 is coupled to and extends between the first hinge 32 and the second hinge 34. The third rod 36 is positioned on the first hinge 32 such that the third rod 36 is positioned to displace the front section 20 horizontally from the rear section 22 as the bicycle 12 is folded.
In one embodiment, each rotator 24 comprises a pipe 38 that is complementary to the front section 20 and the rear section 22. The pipe 38 is positioned around the rear section 22. The pipe 38 is selectively slidably positionable over the front section 20 such that a midpoint 40 of the pipe 38 is positioned substantially equally distant from the front section 20 and the rear section 22. The pipe 38 is positionable over the front section 20 such that the front section 20 is fixedly positioned linearly with the rear section 22.
In another embodiment, the pipe 38 comprises a pair of opposing flat sections 42 that is positioned on an internal surface 44 of the pipe 38. Each of a pair of channels 46 is positioned longitudinally in a respective opposing flat section 42 of the pipe 38. Each of a plurality of balls 48 is rotationally coupled to the front section 20 and the rear section 22. The balls 48 are complementary to the channels 46. The balls 48 are positioned on the front section 20 and the rear section 22 such that the balls 48 are positioned to engage the channels 46 as the pipe 38 is reversibly positioned over the front section 20. The pipe 38 is restricted from rotation relative to the front section 20 and the rear section 22.
A first coupler 50 is coupled to the rear section 22. A second coupler 52 is coupled to the pipe 38. The second coupler 52 is complementary to the first coupler 50. The first coupler 50 is positioned in the rear section 22 such that the first coupler 50 is positioned to reversibly couple to the second coupler 52 to couple the pipe 38 to the rear section 22. Thus positioned, the midpoint 40 of the pipe 38 is positioned substantially equally distant from the front section 20 and the rear section 22. In one embodiment, the first coupler 50 comprises a pair of pins 54 that is positioned in and extendable from the rear section 22. The pins 54 are spring loaded. The second coupler 52 comprises a pair of holes 56 that is positioned through the pipe 38. Each pin 54 is selectively insertable through an associated hole 56 to couple the pipe 38 to the rear section 22.
A bearing 58 is positioned in the rotator 24 that is positioned in the down tube 18. The bearing 58 is positioned in the rotator 24 such that the front section 20 is rotationally coupled to the rear section 22. The front section 20 is rotatable relative to the rear section 22 as the bicycle 12 is reversibly folded. In one embodiment, the bearing 58 is positioned in the third rod 36 such that a first endpoint 60 of the third rod 36 is rotatable relative to a second endpoint 62 of the third rod 36. In another embodiment. The bearing 58 is positioned in the second rod 28 such that a first end 64 of the second rod 28 is rotatable relative to a second end 66 of the second rod 28.
The present invention also comprises a housing 68. The housing 68 comprises an upper shell 70 that is hingedly coupled to a lower shell 72. The upper shell 70 is reversibly couplable to the lower shell 72 such that the housing 68 is reversibly closable. The housing 68 is configured for stowage of the bicycle 12 when the bicycle 12 is folded.
In one embodiment, a plurality of partitions 74 is coupled to and is positioned in the upper shell 70. The partitions 74 define a plurality of compartments 76. In another embodiment, the plurality of compartments 76 comprises four compartments 76. Each of a plurality of lids 78 is positioned to couple to the upper shell 70 and a respective partition 74 to close a respective compartment 76. Each compartment 76 is positioned in the upper shell 70 such that the compartments 76 are configured for storage of items. The lower shell 72 is configured for stowage of the bicycle 12 when the bicycle 12 is folded.
In use, the rotators 24 are positioned in the top tube 16 and the down tube 18 such that the top tube 16 and the down tube 18 are selectively positionable in extended configurations. In the extended configuration, each front section 20 extends linearly from an associated rear section 22 and the bicycle 12 is configured for riding. The top tube 16 and the down tube 18 also are selectively positionable in folded configurations. In the folded configuration, each front section 20 is positioned substantially adjacent to an associated rear section 22 and the bicycle 12 is configured for stowage. Each pipe 38 is positionable over an associated front section 20 such that the associated front section 20 is fixedly positioned linearly with an associated rear section 22. Each compartment 76 is positioned in the upper shell 70 such that the compartments 76 are configured for storage of items. The lower shell 72 is configured for stowage of the bicycle 12 when the bicycle 12 is folded.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
