ATTORNEY.

While there have, in the past, been proposed a'wide variety of connectors for track sections employed in conjunction with model vehicles, such as model railways, and the like, these connectors have not proved entirely satisfactory. In particular,

' prior track connectors have been found readily subject to SUMMARY OF THE INVENTION Accordingly, it is an important object of the present invention to provide a track connector structure of the type described which overcomes the above mentioned difficulties, effectively resists loosening and disconnection under even abusive conditions of operation, while being readily disconnectable by simple, deliberate manipulation.

It is another object of the present invention to provide-a track connector having the advantageous characteristics mentioned in the preceding paragraph, which may effectively form a relatively permanent part of a track section for quick and easy detachable connection therewith to a like track section, thereby effecting substantial savings in time and greatly facilitating the assembling and disassembling procedures.

It is a more particular object of the present invention to provide a track connector of the type described which is extremely simple in construction, being advantageously fabricated of a single integral sheet of resilient material, so as to be durable and reliable throughout a long useful life, and capable of economic mass production for sale at a reasonable cost.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a material part of this disclosure.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIG. 7 is a partial transverse sectional view taken generally along the line 7-7 of FIG. 5.

FIG. 8 is a partial longitudinal sectional view taken generally along the line 8-8 of FIG. 5.

DESCREPTION OF THE PREFERRED EMBODIMENT Referring now more particularly to the drawings, and

specifically to FIGS. l-3 thereof, a connector of the presentinvention is there generally designatedlO, and may adresilient material, such as metal, or other suitable material. The connector 10 includes an elongate generally rectangular base 11 having tapering

end portions

12 and 13 which terminate in respective longitudinally outwardly projecting terminal regions or

tabs

14 and 15. The end tabs- 14 and 15 may be deformed to incline upwardly and outwardly, as by

respective bends

16 and 17, the tabs being resiliently deflectable downward as will appear more fully hereinafter.

Upstanding along each longitudinal side edge of the connector base 11 is a clip 20. In particular, each clip 20 includes an outer generally upright portion 21 integral and generally coextensive with its respective side base edge, and an arcuately inwardly curving upper portion 22 spaced over the base 11. The arcuate upper portion 22 of each clip 20 curves downwardly and terminates in a longitudinally extending, downwardly facing edge 23 spaced over the base 11. Also, the clips 20 and their innermost, downwardly facing edges 23 are adjacent to but spaced from each other. Advantageously, the end edges 24 of the clips 20 are mitred or cut to converge toward each other in the direction longitudinally inwardly of the base 11.

The base 11 is formed at longitudinally spaced locations therealong with a pair of holding formations or detents 26 and 27. In particular, the detent 26 may be located adjacent to the base end portion I2, being spaced inwardly therefrom longitudinally of the base, and may be constituted of a tongue extending longitudinally of the base, being struck up from the material of the base and terminating in a free inner end 28, for a purpose appearing presently. The holding formation or detent 27 may be located adjacent to and spaced longitudinally inward from the base end region 13, and assume the form of a raised dimple or protrusion. It will be observed that the holding formations or

detents

26 and 27 are located generally beneath the downwardly facing inner edges 23 of the clips 20, as best seen in FIGS. 2 and 3.

In FIG. 6 are shown the adjacent end portions of a pair of a, sections, respectively generally designated 30 and 3011, each incorporating a connector as described hereinbefore in connection with FIGS. 1-3, the connectors of respective track sections being generally designated M and 10a. The

track sections

30 and 30a may each include a support, as at 31 and 310, which may simulatea railroad bed and ties. Carried on the

support

31 and 31a are a pair of

parallel rails

32 and 33, a similar pair of parallel rails 32a and 330 being carried on the support 31a. The

rails

32, 33, 32a and 33:: may be secured on the supports by simulated

spikes

34, 35, 34a and 35a, respectively. It will be apparent that the end portions of the

rails

32, 33, 32a and 33a may extend beyond the adjacent end portions of the

supports

31 and 31a. Further, the support 3i may be cut away, as at 36 and 37 to expose the undersides of end portions of the

respective rails

32 and 33; and similarly, the support 31a may be cut away at 360 and 37a to expose the undersides of

respective rails

32a and 33a.

As best seen in FIGS. 6 and 7, the

rails

32 and 32a, which may be identical to

rails

33 and 33a, are of a cross section to accurately simulate full size railway rails. in particular, the

rails

32 and 32a each include a longitudinally extending, laterally enlarged lower portion or flange 4t) and 40a, respectively, an upstanding web 41 and Ma, respectively, and alongitudinally extending enlarged,

upper head

42 and 42a, respectively. In addition, on the undersurface or nether side of each rail flange, adjacent to and spaced inward from the free end thereof, there is a recess, as at 43 and 43a of

respective rails

32 and 32a. Moreover, the recess 43 in the underside of rail flange 40 is generally of right angular configuration including an abutment wall 44 adjacent to the free end of rail 32. The recess 43a may have its sidewalls inclined, as best seen in FIGS. 7 and 8.

In the assembly of FIG. 4, a connector 10 has the adjacent end portion of rail 32 engaged in one end of the connector. More specifically, the end portion of flange 40 rests on the adjacent portion of connector base 11, with the clips 20 extending about respective lips of flange 40 in frictional engagement therewith. That is, the clips 20 extend upwardly, inwardly, and

downwardly so that the free end edges 23 resiliently engage with respective sides of flange 40. in this condition, the end tab 14 is deflected substantially flat for frictional engagement with the underside of the flange 40; and further, the holding tab or tongue 26 has snapped upwardly into adjacent recess 43 with the tab end 28 engageable with recess wall 44 to positively resist removal ofthe connector from the rail 32.

The connector 100 is similarly engaged on the rail 32a and positively retained thereon. Both

connector

10 and 10a extend longitudinally outwardly beyond the ends of their respectively received rails 32 and 320. More specifically, the base and clips of

connectors

10 and 10a extend beyond their received rails.

The outwardly extending regions of

connectors

10 and 10a are adapted to eceive the end portions of

respective rails

33a and 33. That is, the exposed end of rail 33a on the adjacent base portion of connector 10, with the clips 20 extending about and frictionally engaging downwardly with opposite sides of the flange of rail 33a. It will be apparent that the convergent configuration of clip ends 24 adjacent to rail 33a facilitates insertion of the latter into connector 10. Such insertion is continued until holding formation or detent 27 snaps into the nether recess 43a of rail 33a, as best seen in FIG. 8. In this condition, the connector 10a is effectively retained in its connected relation with respect to rail 33a, except upon deliberate separation therebetween. in the connected condition, the resilient tab is deflected downwardly and frictionally engages the underside of the flange of rail 33a, to further aid in retention, while permitting of manual separation, when desired.

From the foregoing, it is seen that the present invention provides a track section and connector therefore which effectively prevents accidental separation of connected track sections, while permitting desired separation and connection of track sections, all without detracting from the accurate simulation in a model of the full size track, and which otherwise fully accomplishes its intended objects.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention.
