DESCRIPTION:
BRIEF SUMMARY
This invention relates to a bridle tension indicator device.
When riding a horse signals for instructing to the horse to perform various acts such as turning in a particular direction, slowing down or stopping are transmitted through the bridle as well as the rider's seat, knee or heel pressure against the horse body.
When a rider is inexperienced at horse riding there is an instinctive tendency for a rider to pull heavily upon the reins to turn or stop the horse even though such action may not actually be necessary in the circumstances prevailing at a particular time. The result of unduly hard pulling on the reins is to pull the bridle bit which is located in the horse's mouth forcefully against the corners of the horse's mouth, in some cases damaging the mouth to such an extent that eventually the mouth becomes insensitive to such instruction leading to the reins being pulled harder to obtain the desired result. This is due to the fact that the rider has not learned that the required signal, for any transition, in a schooled horse, is that of the Half Halt. This is simply a taking and giving of the rein, that may involve no more than a slight closing of the fingers. Together with the use of the back and lumber muscles pushing the seat towards the pommel of the saddle.
It is therefore desirable to provide a device which will assist in teaching a rider how to control the movement of a horse using the reins correctly, and thereby substantially reduce damage to a horse's mouth.
According to one aspect of the present invention there is provided a bridle tension indicator device connectible to a rein of the bridle, characterised in an electric circuit for producing a signal when the tension in the reins exceeds a predetermined amount, switch for initiating operation of the electrical circuit, and an indicator for providing indication that the predetermined tension has been exceeded in response to a signal emitted by the electrical circuit means.
In one preferred embodiment of the invention the indicator device is arranged to emit an audible signal which may be a continuous tone, or alternatively, a synthesized voice instruction. In a further embodiment the indicator may be an indicator lamp which lights up when the predetermined tension is surpassed. The indicator device can be provided with one or both audio/visual indicators, and may also have a liquid crystal display to clearly indicate the timing programme that has been set.
In one preferred form of the invention the indicator device includes a housing in two parts one slidable relative to the other so that when attached to the reins and the reins are pulled straight the parts of the housing are moved apart and cause the indicator circuit to provide the indicator signal. The parts of the housing are biased to a closed position, preferably by a spring the tension in which is adjustable. Conveniently, the indicator device is attached to the reins by threading the reins about a plurality of bars on either part of the housing, or alternatively, by studs or simply loops.
According to another aspect of the present device there is provided a constant level indicator device arranged to be attached to a selected part of a person's anatomy, the device being characterised in an electrical circuit for producing an electrical signal representative of the said deviation from the horizontal or vertical plane, a switch operable in response to the said deviation from a horizontal or vertical plane for initiating operation of the electrical circuit, and an indicator for providing a signal indicative of a deviation from the said horizontal or vertical plane.
In an alternative form of the invention the indicator device includes a housing in two elongate hollow parts one pivotally mounted relative to the other at one end of those parts with a biasing spring attachable between free ends of the elongate parts opposite to the interconnected ends thereof.
In either embodiment the biasing spring biases the indicator device to a closed position thereof and in this position the reins
