Abstract
A track for a toy vehicle is provided. The inventive track includes at least one end segment, either male or female, and at least one middle segment. The middle segment is pivotably attachable to at least one of the male and female segments. A middle segment can have teeth on both ends, tooth-receiving cavities on both ends, or a set of teeth on one end and a cavity on the other. The teeth of one segment are selectively engageable with the edges of a cavity of an adjacent segment. When teeth engage a cavity, one segment is fixedly angled with respect to the other segment. By repeating this pivotably angled structure between a number of segments, the curvature of the track can be altered to the taste and specifications of the user.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a flexible toy track. More specifically, the present invention relates to a flexible track for a toy vehicle having interlinking components, providing an angle to each track segment with respect to its adjacent track segments so as to curve the track and having teeth mating with edges for selectively maintaining the track in a curved configuration.




2. Description of Related Art




For many years, toy trains have been popular, especially among children. Frequently, toy trains are constructed to run along a toy train track. A number of different types of children's toy train tracks have been suggested in the past. These train tracks typically have sections of wood, plastic or metal which are straight or curved and which can be interconnected by the child to form a circuitous toy train track along which a toy train can be rolled without interruption on the track. In one conventional arrangement, a first track section having a tongue at one end is connected by mating the tongue to a receiving slot or groove in a second track section, and this arrangement repeats for the length of the train track. This arrangement generally does not allow for significant flexibility in the construction of a closed loop train track. One problem arises in that the standard curved track has a fixed radius of curvature; it is difficult to create an interesting and closed loop when one has a finite number of choices of curved sections from which to choose. Other structures for interconnecting train tracks that have been used in the past have generally been found to be overly complicated or do not provide a mechanism for locking the train track segments in a selected position of curvature. There is a need for a toy train track that is simple in construction and allows for flexibility in the connection between adjoining train track sections so as to allow the user playing with the track to arrange it in different curvatures as desired while maintaining continuity of the track sections.




SUMMARY OF THE INVENTION




An object of the present invention is to provide a track for a toy vehicle that allows for flexibility in the curvature and connection between adjoining train tracks.




Another object of the present invention is to provide a track for a toy vehicle that may be manipulated by the child to form different curvatures.




Another object of the present invention is to provide a simple mechanism for maintaining a track segment in a curved position relative to adjacent track segments, while maintaining contiguity of the track sections so that a train can pass thereover without derailment.




The above and other objects are fulfilled by the invention, which is a track for a toy vehicle. The inventive track, capable of being curved into a wide variety of curves, includes at least one end segment, and at least one middle segment.




The end segment is at least one of i) a male segment having a tongue projecting from one of a first end and a second opposite end and having teeth protruding from the other of the first and second opposite ends; and ii) a female segment having an aperture to receive the tongue and a first cavity to receive the teeth of either a male segment or a middle segment. The middle segment is attachable to the male segment and/or the female segment and pivotably attaches to at least one of the male and female segments.




The middle segment has any one of the following configurations: i) a second cavity and a second set of protruding teeth disposed on opposite ends of the middle segment; ii) a second cavity and a third cavity disposed on opposite ends of the middle segment; and iii) a second set of protruding teeth and a third set protruding teeth disposed on opposite ends of the middle segment. Thus, a middle segment can have teeth on both ends, tooth-receiving cavities on both ends, or a set of teeth on one end and a cavity on the other. One or more segments can be joined to other middle segments, to male and to female segments.




The first set of teeth of the male segment are selectively engageable with the first cavity of the middle segment and the set of teeth of the middle segment are selectively engageable with the first cavity of the female segment. When the first and second sets of teeth, respectively, engage the first and second cavities, the middle segment is fixedly angled with respect to the end segment. By repeating this pivotably angled structure between a number of middle segments, the curvature of the track can be altered to the taste and specifications of the user. That the teeth of one segment engage the cavity of an adjacent segment means that the angle between two segments (and, by extension, the curvature of the overall track) is “locked” and only adjustable with the application of force; that is, the various segments of the inventive track do not flop around freely and loosely but rather retain their relative positions unless positioned differently by the user.




Further, gaps are preferably provided between the paths formed on the tops of the various segments. As the wheel or other part of the toy vehicle rides over these gaps, it produces a clacking sound which simulates the sound of a running train, for example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT AND THE DRAWINGS




Description will now be given of the invention with reference to the attached

FIGS. 1-8

. It should be noted that these drawings are exemplary in nature and in no way serve to limit the scope of the invention, which is defined by the claims appearing herein below.




A flexible track for use with a toy train, for example, is designated generally by the reference numeral


10


in FIG.


1


. The flexible toy train track


10


preferably comprises one female segment


12


(FIG.


2


), one or more middle segments


14


(FIG.


3


), and a male segment


16


(FIG.


4


).




As shown in

FIG. 2

, the female segment


12


includes a top portion


18


and a base plate


20


, which abut one another by a first side wall


9


and an opposed or second side wall


8


. The first side wall


9


has a first or rear edge


2


and the second side wall


8


has a second or rear edge


3


. The top portion


18


of the female segment


12


includes a center raised section


24


, a raised first wing


26


, and a second raised wing


28


. The center section


24


has a forwardly projecting disc-like tab


25


on one end having a first aperture


30


and a keyhole slot


32


on the other end. A hub or walled portion


31


(see

FIG. 6

) of the center section


24


may extend between the top portion


18


and the base plate


20


and separate the space therebetween into first channel


36


and second channel


38


(see FIG.


2


). The base plate


20


includes a second forwardly projecting tab


27


having a second aperture


34


, preferably substantially aligned with tab


25


and aperture


30


, respectively. Top portion


18


includes a first path or trackway


39


between center section


24


and first raised wing


26


, having a forward end


17


and a rear end


19


and a second path or trackway


29


between center section


24


and second raised wing


28


, having a forward end


11


and a rear end


13


. The first path


39


and second path


29


are recessed beneath the surface of the top portion


18


, each preferably continuous grooves in which the wheels of a toy train, for example, may be guided and travel.




Tabs


25


and


27


extend beyond the rear ends (


3


and


19


) of paths


29


and


39


, respectively. Aperture


30


of disc-like tab


25


is suspended above aperture


34


of tab or disc


27


. In this manner, apertures


30


and


34


form a means for receiving a pivot connection (a vertical cylinder) from a middle segment


14


(see

FIG. 3

, e.g.), and the first and second channels


36


and


38


form a socket-like means for receiving protruding portions of the middle segment


14


. First edge


2


of a female segment


12


contacts a toothed section


66


B (see

FIG. 5

) of a middle segment


14


, and second edge


3


contacts a diametrically opposed toothed section


66


A (see

FIG. 5

) of middle segment


14


. In this manner, the female segment


12


may be locked into an angled position with respect to the first middle segment


14


, as selected by the user of track


10


.




As shown in

FIG. 3

, a first middle segment


14


comprises an interior part


40


integral with an exterior part


41


. As also shown in

FIG. 5

, the interior part


40


comprises wedge segments


60


and


62


having sets of teeth


66


A and


66


B, respectively. Wedge segments


60


and


62


are integral with a center cylindrical segment


61


. The center cylindrical segment


61


is provided with a cylindrical and upwardly directed protrusion


52


, the hinge for receipt between apertures


30


and


34


. Cylindrical protrusion


52


has a smaller diameter than that of the center cylindrical segment


61


. Exterior part


41


has a top


43


and a bottom


42


(see

FIG. 3

) joined by side walls


44


and


46


. These define a cavity


47


. Side wall


44


includes rear edge


48


and side wall


46


includes rear edge


49


. As shown in

FIG. 5

, the exterior part


41


forms an inner circular wall segment


45


. As shown in

FIG. 3

, bottom extends rearwardly to form a fourth disc-like tab or protrusion


63


having a fourth aperture


65


substantially aligned with third aperture


57


located above it.




The top


43


of exterior part


41


has side segments


53


and


54


(See

FIG. 5

) on opposite sides of raised middle section


55


. The middle section


55


extends rearwardly to form a disc-like tab or projection


56


having a third aperture


57


. On opposite sides of middle section


55


, between the middle section


55


and the side segments


53


and


54


are formed path or trackway


59


and another path or trackway


58


, which are respectively separated (yet aligned) from the first path or trackway


39


and the second path or trackway


29


of the female segment


12


(when connected thereto) by coupling interior part


40


and its forwardly extending wings into first and second channels


36


and


38


. Interior part


40


and the trackways are sized with respect to the wheels of a train selected to run on the track so that the wheels of the train do not significantly fall onto or get trapped on the surface of interior part


40


or “derail. ” However, because there is a gap between the various sections -and thus the track paths are somewhat discontinuous (although aligned) - a vehicle such as a toy train passing along the track will make a constant clacking sound as the vehicle passes from one segment to the next. The clacking sound is an auditory feature which further simulates the running of a real train. As such, it is a desirable and entertaining feature.




As shown in

FIG. 1

, a first middle segment


14


A may be connected to the female segment


12


by the protrusion


52


of the first middle section


14


A mating with both the first aperture


30


of the female segment


12


and the second aperture


34


of the female segment


12


(protrusion


52


extends both above and below segment


61


). When the first middle segment


14


A is connected to female segment


12


, wedge or wing segment


60


is notably slidable in and out of the first channel


36


of female segment


12


and the second wedge segment


62


is notably slidable in and out of the second channel


38


of the female segment


12


but in a direction rotationally opposite to that of the movement of wedge segment


60


. In this manner, a user may select an angle between the first middle segment


14


A and the female segment


12


. Wedge segments


60


and


62


provide the appearance to the user of the track that the track is continuous, although it is in fact made of separate segments joined together.




As shown in

FIG. 1

, the first middle segment


14


A may be connected to an identical second middle segment


14


B by inserting the cylindrical protrusion


52


of the second middle segment


14


B into apertures


57


and


65


of the first middle segment


14


A. The second middle segment


14


B has the same structure as the first middle segment


14


A. Wedge segments


60


and


62


of the second middle segment


14


B are notably slidable in and out of the cavity


47


of the first middle segment


14


A. In this manner, the user may select an angle between the first middle segment


14


A and the second middle segment


14


B. A tooth


66


of the second middle segment


14


B may be selected by the user of the track for locking the second middle segment


14


B against third edge


48


. Another tooth of the second middle segment


14


B is thus diametrically aligned by the user of the track for locking a tooth of the second middle segment


14


B against the fourth edge


49


. Thus, the second middle segment


14


B may be locked in a selected angular position of curvature with respect to the first middle segment


14


A. In this manner, successive middle segments


14


may be placed in attachment to each other and temporarily locked in selected positions of curvature. A length of track can be built by adding middle segments.




As shown in

FIG. 4

, male segment


16


may be formed by two components, a base plate


124


and an upper section


126


. As shown in

FIG. 8

, the male segment


16


comprises a second interior section


90


integral with a second exterior section


91


. As shown in

FIG. 8

, the second interior section


90


comprises opposed wedge segments


92


and


96


, each having outwardly extending teeth


166


, which are integrally formed with a center cylindrical segment


95


.




The center cylindrical segment


95


is provided with an upwardly directed centrally located cylindrical protrusion


99


. Cylindrical protrusion


99


has a smaller diameter than that of the center cylindrical supports segment


95


. The second exterior section


91


has a contoured curved wall


108


. The top


112


of the second exterior section


91


has raised side segments


113


and


114


on opposite sides of raised middle section


115


. The cylindrical protrusion


99


of the male segment may hingedly attach to the third aperture


57


and fourth aperture


65


of the middle segment


14


to connect the male segment


16


to an adjacent middle segment


14


. The teeth


166


of the male segment


16


may be locked in an angular position selected by the user against edges


48


and


49


of the middle segment


14


. In this manner, the male segment


16


may be joined to an adjacent middle segment


14


in a similar manner to how the middle segments


14


are joined to each other.




A male segment


16


may be joined to a female-like segment


12


of a straight or another flexible track section to complete a stretch of track. The second exterior section


91


of the male segment


16


has a top


100


and a bottom


101


joined by a second vertical wall


104


and a third vertical wall


105


and forms a second cavity


106


(see FIG.


7


). A tongue


116


protrudes from the middle section


115


and includes a round head


117


. A support


119


may mechanically attach the tongue


116


and head


117


to the interior of the male segment


16


. This support


119


maybe attached by screws through and into the second cavity


106


of the male segment


16


. Side segments


113


and


114


, with middle section


115


form two paths or trackways


121


,


122


, which are aligned with respect to the paths


58


,


59


of the adjacent middle joint segment


14


. However, the second interior segment


90


is sized with respect to the wheels of the train running along the track so that the wheels of the train do not derail, just as stated above. From the view of a user of the toy, the third outer end


93


and the fourth outer end


97


provide an appearance of continuity between the male segment


16


and the adjoining middle segment


14


, although the angle of the male segment


16


may be changed with respect to its connection to the adjoining middle segment


14


. Head


117


is sized to mate with the keyhole


32


of the female segment or to another piece of train track having a similarly sized keyhole.




In this manner, the female, middle, and male sections may be joined together to form a continuous flexible track length upon which a train may be driven. The flexible train track segment may be connected to other straight or specialty track segments. In use, a person may adjust each of the female, middle and male sections to the desired curvature by rotating a track section about a connecting pivot point and allowing a track segment to notably slide into an adjacent track segment. Thus, the person may adjust the angle of rotation, while visual continuity of the track segments is maintained and the train's wheels are maintained in the paths or trackways since they are greater in diameter than the distance between trackways of adjacent segments. The teeth of one segment cooperate with the rear edges or walls of the adjacent segment to maintain the track in the desired curved configuration. After use, the person may disengage the teeth from their locked position and dissemble the train track or merely force a rotation to change the overall curvature or shape. In this manner, the person may repeatedly select and create a track comprised of one or more curved segments having variable curvatures.




The invention is not limited to the above description. For example, it is described above that the middle segments are completely separate but attachable to both the male and female segments to form a track. However, it is also contemplated that the inventive track come pre-assembled in a variety of sections each having a plurality of segments already attached to one another (see, e.g., FIG.


1


). Further, the drawings depict male and female segments having top and bottom portions which are secured or glued together. However, it is also contemplated that the male and female segments respectively be made as integral segments not requiring conjoining.




Also, the invention is described and shown with teeth sections disposed forwardly and corresponding receiving apertures disposed rearwardly on respective segments. However, it is understood that “forward” and “rearward” are relative terms simply meaning opposite ends of a given segment. What is important is that a wedge-shaped toothed section of one segment matingly engage within the cavity of an adjacent segment. For example, all middle segments need not be identical; some middle segments may be provided with wedge-shaped tooth sections on both ends interleaved or alternating with middle segments having mating cavities on both ends. A hinging post need not be located on the same end as a toothed section, and an aperture need not be located on the same end as a cavity; a post could also be located on the same end as a cavity, and an aperture could also be located on the same end as a toothed section.




Having described this invention with regard to specific embodiments, it is to be understood that the description is not meant as a limitation since further variations or modifications may be apparent or may suggest themselves to those skilled in the art. It is intended that the present application cover such variations and modifications, and the scope of the invention is defined by the claims appearing herein below.
