Definitions

  • the present invention relates to a quick coupling device for carriages, trucks and locomotives of miniature electric trains.
  • a common coupling type is the screw coupling, however this is not very suitable for use in model railways as it transmits only traction forces and can be coupled and uncoupled only by hand.
  • Coupling usually takes place automatically by pushing the vehicles one against the other. Uncoupling is accomplished either manually or by a decoupler situated at determined points of the track. Uncoupling at any point of the installation at will is also possible if suitable mechanical or electromechanical devices are present on the vehicle.
  • the couplings can be provided with supplementary devices which predispose them for uncoupling by means of a decoupling device.
  • the vehicles separate only by changing their running direction or by a shoving operation. These couplings are known as "couplings with pre-release”.
  • a particular type of coupling is the short coupling, which allows straight-line running with the buffers in contact. They allow the vehicle ends to withdraw when traversing a curve. Only those coupling types which form a rigid link when in the coupled position are suitable for short coupling.
  • Eye bracket couplings have a movable eye bracket and a fixed hook.
  • the eye bracket is usually tiltable upwards and falls onto the hook of the other coupling. If both the couplings are provided with an eye bracket, the two slide one on the other.
  • These couplings can also be formed with the hooks projecting beyond the front edge of the eye bracket, during coupling they positioning themselves one adjacent to the other. In the coupled position the eye brackets of this variant are not superposed.
  • Hook couplings have a movable hook and a fixed eye bracket.
  • the hook is usually tiltable upwards and falls into the eye bracket of the other coupling. If both the couplings are provide with a hook, the two slide one adjacent to the other.
  • These couplings can also possess an eye bracket that projects beyond the hook; during coupling, these eye brackets slide one on the other.
  • Jaw couplings are formed either with a fixed jaw or with a movable jaw, which engages the counter-jaw by pushing the vehicles one against the other.
  • the jaws are raised or opened by a suitable device on the track.
  • engaging couplings often present a male and a female part and are therefore not identical; hence the problem arises of having to mount them in pairs, and of not being able to change the coupling direction for example of a truck, without replacing the couplings themselves.
  • An object of the present invention is to provide a quick coupling device for carriages, trucks and locomotives of miniature electric trains which is improved compared with the known art.
  • Another object of the present invention is to provide a quick coupling device for carriages, trucks and locomotives of miniature electric trains which is formed from identical pieces and does not present a male and a female part.
  • Another object of the present invention is to provide a quick coupli ng device for carriages, trucks and locomotives of miniature electric trains which is economical and consists of just a few simple pieces.
  • Another object of the present invention is to provide a quick coupling device for carriages, trucks and locomotives of miniature electric trains which can be coupled and uncoupled without manual operation, and hence in a totally automatic manner.
  • the invention also presents a shape which is similar in appearance to the coupling devices present on real vehicles.
  • FIGS. 1 and 1a show a first component of a quick coupling device for carriages, trucks and locomotives of miniature electric trains indicated overall by the reference numeral 1. They also show a second component of the coupler unit, substantially identical to the first and indicated by 1a, to be coupled with the first.
  • the components consist of three pieces, a base body 2, 2a, a plate 3, 3a and a counterweight 4, 4a which are identical.
  • a dovetail shaped region 6, 6a is provided to act as a height-adjustable connector-guide for engagement with snap connectors 5, 5a able to cooperate with conventional NEM pockets (not shown) present on carriages, trucks, locomotives and vehicles in general.
  • the base bodies present pins 8, 8a provided with grooves 9, 9a frontally presenting conical portions 10, 10a. Adjacent to the pins 8, 8a, the base bodies 2, 2a present apertures 11 11a, acting as a guide for the pins 8, 8a respectively during the coupling of the two components 1, 1a. As evident from Figure 3, during coupling the base bodies 1, 1a are disposed such that the faces 12, 12a face each other, and in particular such that the pin 8 faces the aperture 11a; hence the component 1 is in practice reversed relative to the component 1a.
  • the base bodies 1, 1a there are also provided vertical guide holes 13, 13a for appendices 14, 14a rigid with the plate 3, 3a to which there is fixed at 15, 15a an elastic blade 16, 16a presenting a hook-shaped protuberance 18, 18a which when the plate 3, 3a rests on the top 19 of the base body 2, 2a acts as a coupling means for the respective pin 8, 8a.
  • the hook 18 penetrates into the groove 9a of the pin 8a, and simultaneously the hook 18a penetrates into the groove 9 of the pin 8; both the components are hence connected together.
  • the appendices 14, 14a project lowerly therefrom and are secured to a counterweight 4, 4a.
  • the counterweight 4, 4a also presents lead-ins 21, 21a arranged to cooperate with shims 22 for raising said counterweights and consequently the plate 3, 3a, in order to unhook the hooks 18, 18a from the grooves 9, 9a of the pins 8, 8a and hence enable coupling release.
  • Figure 4 shows a condition occurring along a curve, specifically a right hand curve. Hooks and grooves are in contact at the points indicated by P.
  • Figure 5 represents a condition in which the locomotive is pulling in a straight line. Hooks and grooves are in contact at the points C.
