Definitions

  • the present invention relates to a coupling for vehicles of toy and model railroads according to which a onepiece coupling hook, preferably produced by injection molding, is provided With a T-shaped extension, while the vehicle frames to be provided with the coupling have their narrow sides provided with chamberg. with a vertical slot in which the T-shaped extensions are located.
  • a pressure spring acts upon the head of the extension and resiliently maintains the coupling hook in its central position.
  • FIG. 1 is an isometric view of the understructure or undercarriage of a toy freight car with the mounting of the coupling according to the present invention.
  • FIG. 2 is an isometric view of the upper structure to be mounted on the understructure shown in FIG. 1.
  • FIG. 3 illustrates the understructure of FIG. 1 as seen from the top with the front chamber for the mounting of the coupling hook cut open.
  • a vehicle according to the present invention is characterized primarily in that the chambers provided on the understructure of the vehicle are closed toward the bot tom and open toward the top and will be closed by the upper vehicle structure when the latter is mounted on the understructure.
  • the chambers for receiving the T-shaped extension of a coupling hook and the pressure spring are provided in spaced relationship below the platform of the understructure while they are confined at the top by downward extensions arranged on mountings on the vehicle.
  • the chambers which are provided at the narrow or end sides of the understructure are in conformity with the present invention provided with a front recess of a relatively great width for receiving the head of the T- shaped extension, the depth of said recess exceeding that of the head. Said recess is followed by a relatively narrow chamber section which serves for receiving a pressure spring designed as helical spring.
  • the upper structure is provided with conical pins adapted to engage corresponding conical bores in the understructure in such a way that the upper structure will be frictionally connected to the understructure.
  • the understructure or undercarriage 1 which is formed of a single integral piece, preferably by injection molding, has its end portions provided with extensions 2 injection molded together with the other parts for forming mounting or holding chambers for the coupling hooks.
  • Each chamber 2a has a front chamber section 3 which is relatively wide and of rectangular contour for receiving the head 4 of a coupling hook 5.
  • Chamber section 3 is followed by a narrower chamber section 6 the width and height of which corresponds substantially to the diameter of a helical spring 7 the front portion of which extends into chamber section 3.
  • a vertical slot 8 for receiving the neck 5a which interconnects head 4 and hook 5.
  • the chamber sections 3 and 6 are closed from the top by the upper vehicle structure, in the present instance by the upper vehicle part 10.
  • the upper vehicle structure 10 has its bottom portion provided with rectangular extensions 9 which hold helical spring 7 and head 4 of the hook in their respective position.
  • coupling hook 5 is adapted to carry out a tilting movement about head 4 in upward direction and toward both sides.
  • Pressure spring 7 is adapted to return the coupling hook to its normal position.
  • the coupling hook is furthermore adapted within chamber section 3 to spring back by a slight distance toward the interior of the vehicle.
  • the vehicle upper structure is provided with four slightly conical studs 11 adapted to be received by corresponding conical bores 12 in the understructure 1.
  • the introduction of said conical studs into said bores will assure such a firm frictional connection of the upper structure with the lower structure that these parts can be detached from each other only by employing considerable force.
  • the understructure 1 is additionally provided with a central stud 13 and with two thinner studs 14 arranged in longitudinal direction of the understructure ahead of and behind said stud 13.
  • the studs 13 and 14 are intended to position a plate 15 which preferably consists of iron in order to increase the weight of the vehicle. This plate 15 will become invisible after the upper structure 10 has been firmly mounted on the understructure 1.
  • a vehicle according to the present invention as illustrated in the drawing is combined of a one-piece upper structure 10 and a one-piece understructure 1.
  • a multipart upper structure may be employed, for instance in the form of a central portion and two brake houses. In this neck connected to instance these houses will cover the holding chambers for i the coupling and will be provided with corresponding connecting means.
  • the conical pins on the vehicle upper structure it is, of course, also possible to provide conicalbores and to have the understructure provided with conical pins for fitting into said bores.
  • the round pins 13 and 14 there may also be provided conical plane surfaces for the same purpose.
  • the holding arrangement for the coupling hooks has numerous advantages.
  • a special closing means for the chambers in the understructure will be superfluous thereby considerably simplifying the production and reducing the cost of vehicles of the type involved.
  • the employment of pres sure springs in the form of helical springs in combination with the particular design of the chambers will yield a particularly soft rebound of the coupling hooks when pushing a train While the books can be safely returned to their normal position.
  • helical springs made of steel wire can be produced at lower cost than leaf springs which are mostly made of Tomba-k sheet metal.
  • the connection of the upper structure to the understructure by means of conical pins saves the employment of screws and correspondingly threaded bores while still permitting the assembly and disassembly of the vehicles.
  • each of the end portions of said understructure confining a chamber with a bottom while being open at the top, each of said chambers having an outer end wall facing in the longitudinal direction of said understructure and being provided with a substantially vertical slot, two coupling members respectively associated with said chambers, each coupling member having a head arranged within the respective chamber pertaining thereto and also having a said head the respective adjacent slot toward the outside of the respective chamber, each coupling member having that portion thereof which is outside said chamber provided with coupling means for engagement with a coupling member; of another raikvehicle, coil spring .means respectively arranged withinsairlchambers and continuously and resiliently urging the respectiveadjacent headtoward the trespecti-ve adjacentslet, rand auvehicle i'upper ,structure mounted upon said understruct'ure and including means closing the openfe'iidfl'ofsaid -'slots"and also including means insaid chamber for holding said spring means in said
