DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a gambling device with an oscillatory spring rod clamped in a base plate and finished with an operating knob at its upper free end, on which spring rod several disks are arranged for free displacement, of which a lower play disk has symbols such as numerals, letters or other symbols and of which an upper play disk has at least one window, a marking or the like, associated with one of the symbols, a spacer being provided spacing the disks from the base plate in their position of rest, at least the play disks being provided with a ring of locking holes and catching devices being provided associated with the latter.
BACKGROUND OF THE INVENTION
A gambling device of the generic type is known from German utility model 19 86 429. The basic idea of this known gambling device is good; it did not prove successful in practice since the oscillation properties of the whole system needed improvement in particular with regard to a descent of the disks sufficiently expanded in time from oscillation to position of rest in unpredictable angular positions one relative to the other.
SUMMARY OF THE INVENTION
It is accordingly the object of the invention to improve a gambling device of the above generic type such that with the oscillation behaviour improved the disks descend one after the other in sufficient time intervals taking in each case unpredictable angular positions one relative to the other.
The object is attained in accordance with the invention in that, on a catch disk freely displaceable on the spring rod and facing the base plate, the spacer associated with the base plate and the catching devices in the form of catching pins facing the lower play disk are arranged, which catching pins are formed to accommodate all the disks arranged above the catch disk. By the measures according to the invention it is achieved that the lower catch disk having a comparatively great mass together with the spacers and the catching pins also ascends on the spring rod at the beginning of the oscillations thus increasing the oscillating time on the whole. On the other hand this mass is the first to sink downwards. The other disks start to descend only afterwards each in a defined manner. They are all accommodated on the catching pins of the catch disk.
When the spacer consists of several pins each formed integrally with one of the catching pins, a particularly simple technical solution is created for the spacer on the one hand and for the catching pins on the other.
Due to the clamping point of the spring rod being adjustable in height relative to and on the base plate the oscillation behaviour of the entire device can be modified, since the distance between the catch disk supported by way of the spacer on the top side of the base plate in its position of rest and the clamping point of the spring is modified.
When a gyroscopic disk is arranged above the upper play disk, there is the possibility to create another additional play disk amplifying the range of gambling.
The measure of a weight being arranged between the gyroscopic disk and the operating knob for free displacement on the spring rod creates a further possibility to influence the oscillation behaviour on the one hand and the speed of the descent of the disk on the other hand.
When the diameters of openings of the play disks receiving the spring rod decrease from the bottom to the top, this will equally help with the descent of the disks in expanded time intervals.
Further advantages, features and details of the invention will become apparent from the ensuing description of two examples of embodiment taken in conjunction with the drawing.
