Filed May 7, 1959, Ser. No. 811,590 12 Claims. (Cl. 238-) This application is a continuation-in-part of my application Serial No. 348,664, filed April 14, 1953 and allowed November 14, 1958, now abandoned.

This invention relates generally to toy railroads and more specifically to a foldable track coupling used in making foldable railroad train boards composed of pivotally connected sections or panels.

The invention contemplates a new hinge means which not only directly connects the tracks fastened on the foldable panels but which also serves to pivotally unite the panels for folding movement; and it may be used in connection with either electrically or mechanically operated trains.

Various forms of collapsible or foldable track boards and tables have been proposed in which the panels are of wood and are connected to each other by ordinary hinges; and in such prior devices various attempts have been made to connect the track sections fastened to the foldable panels so that the rolling stock will pass over the hinge lines of adjacent panels without derailment and with the minimum of noise and clatter. Some of these prior art devices have been complicated and hence expensive, and due to the warping of the wood panels, it has been difficult to set up the train board for use. The present invention aims to overcome these drawbacks and to greatly simplify the construction of a folding railway board.

The principal object of the invention is to provide a track hinge or coupling so constructed that it will permanently join together the tracks aflixed to adjoining panels and also serve as the means of hinging the panels to each other.

Another object is to provide a track hinge of this character which is of simple and inexpensive construction, which will prevent track separation and ofi-centering should warping occur in the board, and which will maintain permanent horizontal alinement of the track when the board is in use to reduce clatter and eliminate derailment as the train passes over the joint between panels.

Another object is to provide a track hinge of this character which may be sold to purchasers who desire to make their own folding track boards or tables, thus enabling many, who could not afford to buy a complete assembled train set board, to have a satisfactory foldable board.

Another object is to provide a track hinge of this character for use with electrically operated trains, which eliminates the necessity of providing auxiliary electrical contact devices with wires strewn over or under the board, or the provision of auxiliary measures to bridge the gap between track elements which would otherwise terminate near the panel joints.

With the above and other objects and advantages in view, the invention resides in the novel combinations and arrangements of parts and novel features of construction hereinafter described and claimed, and illustrated in the accompanying drawings which show the present preferred embodiment of the invention.

In the drawings:

FIG. 1 is a somewhat diagrammatic plan view of a foldable toy railway board in its open position and constructed in accordance with my invention;

FIG. 2 is a side view of the same;

Patented Aug. 29, 1961 3 ice FIG. 3 is a view similar to FIG. 2 but showing the device in its folded or closed position;

'FIG. 4 is a detail perspective view on an enlarged scale of one of the track couplings or hinges and two adjoining panels, the latter being broken away and in section;

FIG. 5 is an exploded view similar to FIG. 4;

FIG. 6 is a detail side view on an enlarged scale of a portion of the device in its foldable position, parts being broken away and in section; and

FIG. 7 is a detail vertical section taken substantially on the line 7-7 in FIG. 4.

Referring more in detail to the drawings FIGS. 1, 2 and 3 show somewhat diagrammatically one form of folding railroad board which may be constructed by the use of my improved hinges which perform the double function of pivotally connecting the foldable panels and of being a part of the trackage for the rolling stock. As Shown the board has a center section or panel 10 and two end sections or panels 11 which fold from their horizontal positions in FIGS. 1 and 2 to their upright positions in FIG. 3. The rectangular panels which are preferably made of plywood, may be fastened to rectangular supporting frames composed of furring strips 12 extending along all four edges of the panels. The center panel is preferably about 20" wide so that the device when folded may readily pass through a doorway. The center panel may be supported on four casters 13 to permit rolling of the folded device into storage space. To retain the two side or end panels in folded position a suitable upright backstop or support 14 may be fastened to one end of the center panel, and hooks 15 and coacting eyes 16 may be used, as shown in FIG. 6, to temporarily connect these parts. If desired a backstop may be at each end of the center panel and it may be an ornamental device, carry a sign, etc., but as shown it consists of two spaced uprights 17 fastened at their lower ends to the panel and having their upper ends connected by a horizontal bar 18, the ends of which stop the end panels 11 when they reach vertical positions, as seen in FIGS. 3 and 6. At the outer corners of the panels 11 may be fastened blocks 19 to serve as supporting feet to assist in holding these panels, when lowered, in the horizontal plane of the center panel .10. On one or more of the panels may be mounted a transformer, control box, etc., as conventionally illustrated at 211.

My new track hinge or coupling is indicated as a whole by the numeral 21, and one will be used at each point where a line of track crosses a joint between the panels. The trackage system or rail layout will vary according to the size of the board and the desire of the owner, but as shown in FIG. 1 there is a continuous main track 22 with opposed straight portions and a siding 23 parallel with one of the straight portions so that three track lines cross the joints between the center stationary panel 10 and the two foldable end panels 11.

Each of the hinges 21 comprises two members 24 and 25 connected by a pair of alined pivots 26. The members 24 of the several hinges are fastened along the longitudinal edges of the center panel by screws or similar fastenings 27, while the members 25 are similarly fastened as at 28 along the adjacent edges of the panels 11 and in opposed relation to the respective members 24 so that the panels will swing about the several pivots or hinge pins 26; all of the latter along each joint being in axial alinement.

The members 24 and 25 of each pair are of the same construction except at their pivotally connected ends; and each comprises a fiat and elongated or rectangular attaching or base plate 29 along the edges of which are upstanding parallel track bars or rails 30 which form portions of the track lines on which the wheels of the rolling stock run. The remaining portions of the track lines 22 and 23 are composed of the standard track units now commonly used in toy railroads. These units consist of parallel track rails connected by cross ties and a central current conductor rail insulated from the cross ties. The heads of the rails are tubular to form socketed ends and in the sockets at one end of the unit are frictionally retained coupling pins to enter the sockets of the next adjacent unit. Preferably one of these track units 31 is fastened on the panel between the two members 24 in each of the track lines as shown in FIG. 1. The ends of the hinge track bars or rails 30 are formed with sockets 32 to frictionally retain coupling pins 33 which enter the sockets in the track rails of the units 31, as well as the track units which are fastened to the panels 11 and which abut the hinge members 25, as will be understood on reference to FIGS. 1 and 4.

When electric trains are to be used on the board, each track hinge 21 may have suitably mounted on the base plate of each of its members 24 and 25, a centrally located electric conductor rail 34. Such third rails may be of various constructions but I preferably make them similar to the track rails 30 and pivotally connect them at the hinge line between the base plates 29. These conductor rails 34 may be rectangular metal bars supported on strips 35 of insulating material and rigidly fastened to intermediate portions of the attaching plates 29 by machine screws insulated from such plates, or fastened in any other suitable manner parallel with the rails 30. The far ends of the rails 34 terminate in the vertical plane of the adjacent ends of the rails 30: and are formed with sockets to receive and retain coupling pins 36 which are similar to the pins 33 and enter sockets in the conductor rails of the usual track rail units 31. The near or adjoining end of the conductor rails 34 of each hinge unit are hingedly connected by overlapping joints in the manner of the track rails, as presently described.

The hinge members 24 and 25 are preferably made of metal and have sufficient strength to serve as effective hinges for the panels. While they are shown as having their track bars 30 cast or formed integral with their base plates or hinge leaves 29, they may be made of multiple pieces spot welded, riveted or otherwise suitably assembled; and they might be stamped out of sheet metal. While holes for the fastening screws 27 and 23 might be formed in the plates 29, the screws are shown in openings in the rail bars 30 and have their heads flush with the tops of the latter.

Overlapping joints are provided as shown in FIGS. 4 and 5, at the pivotal connections between the: track rail portions 30 of the members 24 and 25 of each track hinge to insure smooth passage of the wheels of the rolling stock over the joints and to reduce clatter and noise. The pivotal connections are near the top or wheel engaging portions of the rails and permit the latter to swing upwardly. The hinge pins 26 are in alined holes in the reduced and overlapped portions 39 and 40 of the rails 30 of the two members. The ends of the portions 39 on the rails of the member 24 are beveled at 41 to engage undercut portions 42 on the rails of the member 25. The end portions 40 of the rails of the member 25 project beyond the edge of the panel 11 and the extremities of these portions 40 are rounded at 43 to clear the panel 10. This structure provides strong and eifective hinge joints and insures horizontal alinement of the track rails so the trains will pass over the joints of the panels without derailment and with the minimum of noise. As above noted when the conductor rails 34 are used on the base plates 29 of each unit, their adjoining ends have reduced and overlapped portions 45 and 4-6 pivotally connected by hinge pins 47. The latter are in axial alinement with the pins 26 of the track rails 30. By thus connecting the conductor rails in the same manner as the track rails, the hinge unit is strengthened and its appearance improved. At the same time, the cost of producing the hinge unit is reduced. My new track hinge may be sold in pairs or sets and will enable anyone handy with simple tools to out plywood panels of the desired thickness and size, and then mount the hinges and track units so as to have a folding train board at small expense. The track hinges are of universal application for either mechanical or electrically operated trains, and for simple or elaborate track layouts. The track hinges make it possible to construct a trouble free folding train board which overcomes positively the damaging result of board warping and which insures the continuation of the track across the area where sections of the train board join.

From the foregoing, taken in connection with the accompanying drawing, it will be seen that novel and advantageous provision has been made for carrying out the objects of the invention, and while preferences have been disclosed, attention is invited to the possibility of making variations within the scope of the invention as claimed.
