ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an actuating device, in particular drive, preferably for sequences of motion in the field of model building, with at least one magnetic-field producing component, in particular a coil, for generating a magnetic field and an adjusting member that is adjustable relative to a main body, which can both be adjusted relative to one another on the charging of the coil and a coupling device, in particular for a model railway vehicle, comprising a main housing and at least one retainer and/or a pivot lever.
2. The Prior Art
An actuating device, in particular a coupling device for model railways for automatically connecting and disconnecting two model vehicles with a locking element and at least one coupling head is already known according to DE 196 12 263 C1. Said coupling device comprises a coupling head, which engages in a recess of the coupling device, the coupling heads being in contact electrically and being designed as electrically conductive contact strips. Using this design a simple conductive connection is indeed produced between the individual vehicles of a train system in a model railway, but additional manipulation is required for separating the coupling devices of two model railway vehicles from one another.
Furthermore, a drive in the form of an actuating device which has two magnetic coils is known from the 97/98 catalogue of the company Viessman, p.5, wherein spiral springs transfer the force of the magnetic coils to a brake piston. The brake piston here has a damping effect on the drive. The disadvantage of this drive is primarily the complicated construction. In addition, this drive is not suitable for all movements.
Experiments with modern technological materials have also been carried out, such as multi-layer materials or memory metals as well as elements of the type known from sensor technology to piezo-elements. Since the costs of the development and also of acquiring the parts are very high, their use in the sphere of model construction is still at least presently not possible.
SUMMARY OF THE INVENTION
The objective of the present invention is to create an actuating device, in particular a drive for movement sequences, in which with a simple structure a high adjusting force is obtained. The objective of the invention is also to create coupling devices which, when arranged at any point on the train system of a model railway, enable the coupling connection between two such coupling devices to disconnect automatically.
Said objective of the invention is achieved in that the magnetic force for producing the relative movement is increased in the direction of the relative movement between the coil and the adjusting member and/or the main body. It is advantageous here that in this way a lower structural height for such an activating device with equal adjusting force can be created, and thus the use of such an actuating device is possible in microsystems and miniaturised motion sequences. A further advantage is that, on the restoring of the actuating device, in particular the adjusting member, the same adjusting force is available, so that the adjusting member can always be returned to its position of rest.
It is also advantageous that conventional components can be used and thus the cost of manufacturing the actuating device can be kept low.
Other advantages are that by a single charge of the magnetic-field producing component with power an attraction force and a repulsion force can be created simultaneously.
It is also advantageous, when the adjusting member of the actuating device forms a coupling part for a coupling device of model vehicles, in particular a model railway vehicle, as thereby an inexpensive production of coupling devices for model railway vehicles is possible.
A further advantage is that different forces for the attraction force and repulsion force can be created.
Furthermore, the invention also comprises a coupling device, in particular for a model railway vehicle, comprising a main housing and at least one retainer and/or a pivot lever.
Said coupling device, in which the coupling device is assigned an actuating device, is advantageous, because by the arrangement of the actuating device in the coupling device of a model railway vehicle at any given point, the detachment of a coupling connection between two model railway vehicles is possible by using at least one such coupling device.
In addition it is advantageous, that a considerable increase in the adjusting force is achieved.
Furthermore, an electrically remote-controlled coupling device between model vehicles, in particular between model railway, is important, as hereby a coupling connection can be formed between identical coupling heads and then broken by remote control. To break the coupling connection it is merely necessary to activate only one of the two electromagnetic drives or actuating devices, in order to detach the so-called double locking coupling connection or the double hook coupling. This is achieved in that the electromagnetic drive of one of the two coupling devices is coupled in motion with the corresponding coupling parts of the other, assigned coupling device.
Lastly, it is advantageous, when a pivoting or restricted rotary drive is created for detaching a coupling connection between model railway vehicles, which has high functional safety and permits relatively high adjustment movements at high adjusting force.
