Description




BACKGROUND OF THE INVENTION




1. Field of the Disclosure




The subject disclosure relates to children's toy train sets, and more particularly to an improved flexible track.




2. Background of the Related Art




Many variations of toy train sets have been suggested in the past. Techniques for fabrication have included using wood, plastic, metal or a combination of the same. Typically, toy train sets are assembled and played with either on the floor or a table.




Generally, wooden toy train sets include sections of wood toy train track which are of various shapes and sizes. A young child needs to easily interconnect the various shapes and sizes to form the desired pattern over which to roll the toy train. The more sophisticated and complex the track pattern becomes, the more the child enjoys assembly and play therewith.




Toy train tracks are commercially available from a multitude of companies such as BRIO® Corporation having an office in Milwaukee, Wis. and Learning Curve International, L.L.C. of Chicago, Ill. Track sections available from these and other companies include straight as well as curved sections, cross and switch sections, as well as ascending and descending track sections. Bridges, ramps and track supports of various kinds are often provided to allow elevating the track sections. Toy train track components and systems are described in the patent literature, e.g., U.S. Pat. No. 4,841,104 to Adell and U.S. Pat. No. 6,009,812 to Ernst.




Suspension bridges have been developed to interconnect with wooden toy train track sections. Generally, a suspension bridge has a pair of stanchions for supporting each end of a suspension bridge section. In a suspension bridge (commercially available from BRIO® Corporation of Milwaukee), the suspension bridge section has a plurality of segments fixed in place by two lengths of cord disposed through a series of holes aligned in parallel in the segments. As a result, the suspension bridge section has a limited ability to flex in a vertical direction.




In view of the above, there are opportunities to improve based upon the prior art of toy train tracks. For example, previous track sections required many expensive specialized pieces to create desired shapes. Therefore, a need exists for an improved toy train track section that permits easy and efficient track assembly and can solve problems of mismatch.




SUMMARY OF THE INVENTION




The present invention provides a toy track section for play on a substantially planar surface including a plurality of spaced segments. Each of the plurality of spaced segments defines at least one groove in at least one surface thereof and an orifice formed therethrough. A cable extends through the orifices formed through the plurality of segments. A first end connector captures a first end of the cable and a second end connector captures a second end of the cable. The cable permits the plurality of segments to flex relative to each other on the substantially planar surface.




Another embodiment of the present invention includes a toy track which includes a plurality of elongated segments. Each of the plurality of elongated segments has opposed upper and lower surfaces and an outer peripheral wall extending between the upper and lower surfaces defining opposing lateral wall portions. Each of the plurality of elongated segments also has a length along a first axis and a width along a second axis. The first axis is substantially perpendicular to the second axis and each of the plurality of segments is adapted and configured to allow the toy track section to flex in a plane defined by the first axis and the second axis.




These and other unique features of the system disclosed herein will become more readily apparent from the following description, the accompanying drawings and the appended claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




The present disclosure overcomes many of the prior art problems associated with toy train tracks. The advantages, and other features disclosed herein, will become more readily apparent to those having ordinary skill in the art from the following detailed description of certain preferred embodiments taken in conjunction with the drawings which set forth representative embodiments of the present invention.




Referring to

FIG. 1A

, a first embodiment of a toy train track section generally designated


100


is illustrated. Section


100


has a plurality of segments


102


(


a


)-(


n


) which collectively form two grooves


104




a


and


104




b


for the opposing wheels of a toy train to ride within. A cable


106


secures and aligns each segment


102


(


a


)-(


n


) in position along axis “y”. Furthermore, each segment


102


(


a


)-(


n


) can independently rotate about cable


106


. Collars


112


(


a


)-(


m


) (wherein m=n+1) create spacing between segments


102


(


a


)-(


n


). The variables “n” and “m” represent the numbers of segments


102


and collars


112


, respectively, and are in no way intended to limit the potential length of toy train track segment


100


. In a preferred embodiment, segments


102


(


a


)-(


n


) are made from wood, cable


106


is made from a nonelastic material such as stainless steel or the like and collars


112


are made from a molded plastic. In an alternative embodiment, no collars are provided and the spacing of individual segments


102


(


a


)-(


n


) is not uniform in nature. Segments


102


(


a


)-(


n


) have opposed upper and lower surfaces,


105


and


107


, respectively. An outer peripheral wall


109


extends between the upper surface


105


and the lower surface


107


.




Still referring to

FIG. 1A

, section


100


terminates in male and female connectors


108


and


110


, respectively. Male connector


108


has a protrusion


114


for engaging a bore in a female end connector, e.g., of an adjoining track section. Female connector


110


has a bore


116


for receiving a protrusion in a male end connector of an adjoining track section. Therefore, by varying the length and combination of end connectors, section


100


can be easily integrated with any combination of similar or complimentary train track sections.




Referring now to

FIG. 1B

, a top view of alternative end connectors is illustrated. End connectors


170


are unisex and identical. Each end connector


170


has a finger


172


and defines a cavity


174


to capture the finger


172


of an adjacent track section. Additionally, track sections may terminate in segments having opposing hook and loop locking fabric or magnets located on end connectors in order to sufficiently engage adjoining segments




Referring now to

FIG. 2

, a top view of a first embodiment, according to

FIG. 1A

, illustrates the flexibility of section


100


. Section


100


can be shaped into lines, semi-circles, sinewaves and like arcs, and may be used in combination with other segments, e.g., segments fabricated according to conventional techniques and according to the present disclosure to create a desired pattern. Despite flexing of section


100


in a horizontal plane defined by axis “x” and “y” in

FIG. 1A

, grooves


104




a


and


104




b


still effectively guide opposing wheels of a toy across each segment


102


(


a


)-(


n


) of section


100


.




Referring now to

FIGS. 1-4

, cross-sectional views along lines


3





3


and


4





4


of

FIG. 1A

are illustrated in FIG.


3


and

FIG. 4

, respectively. Female connector


110


includes a hole


120


, which receives cable


106


and intersects aperture


122


. A cable stop sleeve


124


is crimped onto cable


106


within aperture


122


. As a result, the end of cable


106


is securely located within hole


120


between aperture


122


and bore


116


. Therefore, the end of cable


106


will not scratch or be accessible by a child playing with section


100


. Cable stop sleeve


124


may be fabricated from a variety of material, e.g., brass, steel, aluminum and the like. Although not shown, the other end of cable


106


is similarly captured within male connector


108


.




Referring now to

FIG. 4

, grooves


104




a


and


104




b


are formed in the top and bottom side of female connector


110


to create symmetry about the “x” axis. Therefore, even though female connector


110


may rotate about cable


106


, alignment of grooves


104




a


and


104




b


will still be maintained with adjacent segments. Moreover, male connector and segments


102


(


a


)-(


n


) are symmetrical about the “x” axis. Therefore, grooves


104




a


and


104




b


effectively guide opposing wheels of a toy across the entire length of section


100


regardless of which grooved sides of segments


102


(


10


)-(


n


) are upwardly positioned. When the segments


102


(


a


)-(


n


) are rectangular as shown, the outer peripheral wall defines opposing lateral wall portions. As shown, outer peripheral wall portions


111




a


and


111




b


form opposing sides of the segments. As will be appreciated by those skilled in the art upon review of the subject disclosure, the portions of the outer peripheral wall


109


between portions


111




a


and


111




b


will also form opposing lateral wall portions.




In another embodiment, a track section may consist of a single symmetrical substantially rectangular segment. Thus, ease of assembly is facilitated because a small child does not need to orient a particular side upwardly. Further, engagement of male and female end connectors in not required because the single symmetrical substantially rectangular segments simply abut each other. It is envisioned that the single symmetrical substantially rectangular segment may be adapted and configured to engage other segments with end connectors, hook and loop locking fabric, magnets or the like.




Still referring to

FIG. 4

, it is also envisioned that each segment may be of two-piece construction. For example, the two pieces may comprise segment portions above and below the “x” axis; thus, each piece would be identical. Preferably, the two pieces may be adhered to each other, e.g., with a glue or other adhesive, and hole


120


may be drilled therein. Additionally, it is envisioned that two piece end connectors may sandwich the end of cable


106


between the two pieces, thereby simplifying the cable retention method and reliably securing the cable end.




Furthermore, it will be appreciated that a cross-section profile may have different groove configurations which are symmetrical about the “x” axis. For example, a single groove or three grooves may be provided in order to accommodate a ball or a tricycle, respectively. It is envisioned that many types of toys may be adapted to travel upon the toy track disclosed herein. Some examples include, but are by no means are limited to, animals, bobsleds, buses, cars, people, trucks and vans.




Turning to

FIG. 5

, a top view of a second embodiment of a toy track section


200


is illustrated. Section


200


has a plurality of segments


202


(


a


)-(


n


) which collectively form two grooves


204




a


and


204




b


for the opposing wheels of a toy train to ride within. Section


200


terminates in a female connector


208


. It is envisioned that a male connector or combination thereof could be utilized to terminate section


200


. Band


206


secures and positions each segment


202


(


a


)-(


n


) and end connectors. In the preferred embodiment, band


206


is made from a nonstretch flexible material that will not allow end connectors or segments


202


(


a


)-(


n


) to substantially rotate about axis “y”.




Still referring to

FIG. 5

, section


200


flexes into various arcs and linear segments to create a desired pattern. Despite flexing of section


200


, grooves


204




a


and


204




b


still effectively guide opposing wheels of a toy across the entire length of section


200


.




Referring now to

FIG. 6

, a cross-sectional view along line


6





6


of

FIG. 5

is illustrated. Segment


202




a


has a rectangular notch


220


which is adapted to receive band


206


. Preferably, the edge of band


206


is permanently glued into notch


220


along the entire length of each segment


202


(


a


)-(


n


). Although not shown, it will be appreciated that each segment


202


(


a


)-(


n


) and the opposing end connectors define rectangular notches and are also glued to band


206


. Preferably, band


206


is rectangularly shaped in order to help prevent segments


202


(


a


)-(


n


) from rotating.




Turning to

FIG. 7

, a top view of a third embodiment of a toy track section


300


is illustrated. Although monolithic, section


300


has a plurality of segments


302


(


a


)-(


n


) which collectively form two grooves


304




a


and


304




b


for the opposing wheels of a toy train to ride within. Section


300


terminates in a female connector


308


. It is envisioned that a male connector or combination could be utilized to terminate section


300


. In a preferred embodiment, section


300


may be fabricated from a variety of materials such as molded plastic, wood, metal or the like.




Still referring to

FIG. 7

, pairs of opposed key-shaped slots


306


(


a


)-(


m


) and


307


(


a


)-(


m


) separate segments


302


(


a


)-(


n


). When toy train section


300


is linear along axis “y”, slots


306


(


a


)-(


m


) and


307


(


a


)-(


m


) are perpendicular to the plane defined by the “x” and “y” axis. Diametrical webs


312


(


a


)-(


m


) remain to connect each pair of opposing slots


306


(


a


)-(


m


) and


307


(


a


)-(


m


). As a result, each segment


302


(


a


)-(


n


) will rotate about the “z” axis as shown in FIG.


8


. As a result, section


300


can also be shaped into various arcs and linear segments to create a desired pattern and despite flexing section


300


, grooves


304




a


and


304




b


still effectively guide opposing wheels of a toy across the entire length of section


300


.




In a further embodiment of the present disclosure,

FIG. 9

depicts a top view of a toy train track section designated generally by reference numeral


400


. Track section


400


has a plurality of segments


402


(


a


)-(


n


) which collectively form grooves to guide a toy train. The variable “n” represents the numbers of segments and is in no way intended to limit the length of track section


400


. A cable


406


secures and aligns each segment


402


(


a


)-(


n


) in position along axis “y”.




Still referring to

FIG. 9

, segments


402


(


a


)-(


n


) can rotate about cable


406


. Segments


402


(


a


)-(


n


) are substantially rectangular in shape. Protrusion


412


(


a


)-(


n


) on each segment provides spacing between segments


402


(


a


)-(


n


) in order to allow the track section


400


to flex into arcs while maintaining a groove to guide a toy. Protrusions


412


(


a


)-(


n


) may be of any functional shape, e.g., dome, hemi-tubular and the like.




In another embodiment, each segment


402


(


a


)-(


n


) may have a hollow to complement each protrusion. Hollows may be of any functional shape, e.g., cone, trough and the like. In still another embodiment, each segment


402


(


a


)-(


n


) may be ferrous and each protrusion


412


(


a


)-(


n


) may be magnetic. Therefore, segments


402


(


a


)-(


n


) can remain attached without having a cable therethrough. It is envisioned that the end segments of track section


400


may have protrusions to maintain spacing and further be adapted to engage other segments by any sufficient means.




With reference to

FIG. 10

, a further embodiment of the present disclosure is depicted. Track section


500


has a plurality of segments


502


(


a


)-(


n


) which collectively form grooves to guide a toy. The variable “n” represents the numbers of segments and is in no way intended to limit the length of track section


500


. A cable


506


secures and aligns each segment


502


(


a


)-(


n


) in position along axis “y”.




Still referring to

FIG. 10

, each segment


502


(


a


)-(


n


) has six sides, e.g., hexagonal. Two sides of segments


502


(


a


)-(


n


) are of equal length and parallel axis y. The remaining four sides are diagonal to axis y to form a point at the location where cable


506


passes through each segment


502


(


a


)-(


n


). As a result, gaps


514


(


a


)-(


m


) are formed to allow track section


500


to flex into arcs as well as straight sections as desired while maintaining a groove to guide a toy. In another embodiment, each segment


502


(


a


)-(


n


) has five sides, e.g., pentagonal. Preferably, pentagonal segments form a point only on one side at the location where cable


506


passes through. It is envisioned that the end segments of track section


500


may have two diagonal sections to create a point to maintain spacing and further be adapted to engage other segments by any sufficient means.




Having thus described several embodiments, it will be observed that at least the following advantages are accomplished. Ease of assembly is achieved by the symmetry of the segments which rotate about a cable and the various end connectors. A multitude of shapes may be formed from a single section. The resulting sophisticated patterns enhance enjoyment from building and playing with the track patterns. Further, the track sections can integrate with conventional pieces to augment and enhance current sets as well as easily solve mismatches.




While the invention has been described with respect to preferred embodiments, those skilled in the art will readily appreciate that various changes and/or modifications can be made to the invention without departing from the spirit or scope of the invention as defined by the appended claims.
