The present invention relates to improvements in or relating to clocks, and in particular to mechanical clocks.
Mechanical clocks are well known and are perceived as high luxury given the strong technical skill and craftsmanship involved in their manufacture. Clocks of this type comprise a winding mechanism which must be periodically wound in order for the clock to maintain its function. Fixed mechanical clocks generally must be wound using a winding key or similar. However, portable clocks, for example watches, have been developed whereby the winding mechanism of the watch is wound through natural movement of the watch itself, for example, when worn on a user's wrist. Such watches may be referred to as “automatic” watches. An automatic watch self-winds using the movement of the wearer, such as the movement of the wearer's wrist or arm during every day movements such as walking. The movement of the wrist, arm and body cause a metal weight attached to a winding mechanism (“the rotor”), to pivot freely on its axis in the centre of the movement. The rotor rotates back and forth in a generally circular motion through action of the wrist, arm or body of the user. The rotor's movement winds the main spring, generally a flat coiled spring that powers mechanical watches.
It is common for clocks to be included within a motor vehicle. Clocks of this type are commonly battery or electrically powered rather than mechanical. However, it would be advantageous to be able to provide a mechanical clock within a vehicle given the perceived higher level of quality. Unfortunately, given the requirements of mechanical clocks to be wound periodically, it is not at present possible to do so without the need for a user to manually wind the clock given that the natural movement of a vehicle will not necessarily automatically wind the clock. Furthermore, given that it is possible in some situations for a vehicle to remain idle for a long period of time, such as overnight for example, a known mechanical clock within a vehicle would not function properly as it would not be wound frequently enough. It would therefore be advantageous to provide a mechanical clock which can be located within a vehicle which does not suffer the drawbacks of the prior art.
It is therefore an aim of an embodiment or embodiments of the present invention to provide a mechanical clock which is an improvement on the prior art.
According to a first aspect of the present invention there is provided a mechanical clock having a winding mechanism and a means to automatically wind the winding mechanism of the clock; wherein the automatic winding means is directly or indirectly powered or actuated by an electrical system of a motor vehicle, in use.
The clock may be an automatic clock. The automatic clock may function as hereinabove described with reference to automatic watches.
In this way, the electrical system of a connected motor vehicle may power the winding of the winding mechanism without the need for a user to manually wind the mechanism. The mechanical clock of the present invention therefore allows for the provision of a mechanical clock within a vehicle without the drawbacks of the prior art.
In some embodiments, the automatic winding means may be operable in use to continuously wind the winding mechanism. Alternatively, the automatic winding means may be operable in use to wind the winding mechanism in a periodic manner. The automatic winding means may be operable to wind the winding mechanism at least every 10 minutes, or at least every 30 minutes, or at least every 45 minutes, or at least every 1 hour, for example. The automatic winding means may be operable to wind the winding mechanism for at least 1 minute, or at least 2 minutes, or at least 5 minutes, for example.
In some embodiments the automatic winding means may comprise a winding key which is mechanically connected to the winding mechanism by means of one or more rotational cogs. In this way, the winding key may be operable in use to rotate axially to automatically wind the winding mechanism, with the rotation of the winding key being powered by the electrical system of the connected vehicle.
In embodiments in which the mechanical clock is an automatic clock, the automatic clock may comprise means to automatically wind the winding mechanism of the clock through movement of the clock, and the means to automatically wind the winding mechanism may comprise a means to move the clock. The means to move the clock may comprise a means to rotate the clock.
Therefore in a second aspect of the invention there is provided an automatic mechanical clock comprising a winding mechanism and a means to automatically wind the winding mechanism of the clock through movement of the clock, preferably rotational movement, wherein the movement is powered or actuated by an electrical systems of the motor vehicle, in use.
In a third aspect of the invention there is provided an automatic mechanical clock comprising an automatic winding mechanism powered or actuated by movement of the clock, and further comprising a clock movement mechanism powered by an electrical system of a motor vehicle, in use.
In a fourth aspect of the invention there is provided a motor vehicle to which is connected an automatic mechanical clock comprising an automatic winding mechanism powered by movement of the clock and a clock movement mechanism powered by an electrical system of the motor vehicle.
In some embodiments the clock is an automatic clock including a winding key, the winding key comprising a rotational cog which rotates the entire clock. In this way, the winding key may be operable to rotate axially in order to rotate the entire clock, and actuate the automatic, self-winding mechanism.
In other embodiments the automatic winding means may comprise a portion of the face of the clock operably connected to the winding mechanism. In such embodiments, the face of the clock may be rotatable in order to wind the winding mechanism.
In embodiments wherein the clock or face of the clock is rotatable, the clock or face may be operable to rotate fully (i.e. 360°) in order to wind the winding mechanism. In such embodiments, the clock or face of the clock may be operable to continuously rotate to wind the winding mechanism for the length of time for which the winding mechanism is to be wound. In other embodiments the clock or face may rotate only partly (i.e. less than 360°). In such embodiments, the clock or face of the clock may be operable to repeatedly rotate to a certain extent to wind the winding mechanism for the length of time for which the winding mechanism is to be wound. In either case, the automatic winding means may be operable in use such that subsequent to rotation of the clock or face for the set period of time, the clock or face is returned to a set position.
In some embodiments the face of the clock comprises one or more indicators thereon which may comprise numerals, such as Arabic numerals or Roman numerals, for example. Preferably, in embodiments wherein the clock or face of the clock is rotatable, the set position to which the clock or face is returned subsequent to winding comprises a position whereby the indicator for 12 o'clock is centred at the top of the clock.
The mechanical clock may additionally comprise a positional sensor. In some embodiments the sensor may be operable in use to determine the rotational position of the clock itself, or in some embodiments the rotational position of the face of the clock. In this way, the sensor may be operable in use to determine whether the clock or face of the clock has been returned to its set position subsequent to winding. Furthermore, the sensor may be operable to determine whether the clock itself is returned to a correct configuration subsequent to movement of the clock itself In some embodiments the positional sensor comprises an optical sensor.
The electrical system of the vehicle will commonly be powered by a battery, such as a car battery, for example. In some embodiments the automatic winding means of the mechanical clock may be operable in use to automatically wind the winding mechanism of the clock irrespective of whether the engine of the vehicle is operational or is turned off In this way, the automatic winding process may carry on even when the vehicle is not in use.
In some embodiments the mechanical clock comprises a rotational mechanism operable in use to rotate the hands of the clock to indicate the time to a user. In such embodiments, the rotational mechanism may also be powered by the electrical system of the connected vehicle. In this way, the time displayed by the hands of the clock may be altered automatically by the vehicle, or by a user's interaction with the vehicle. In further embodiments the rotational mechanism of the clock may not be electrically connected to the vehicle. In such embodiments, the mechanical clock may additionally comprise a crown wheel operable in use to act upon the rotational mechanism to move the hands of the clock. In such embodiments, the mechanical clock may also comprise a means to move the clock itself in such a way so as to present the crown wheel to a user for altering the time displayed by the clock itself In some embodiments the movement means may be operable to rotate the clock into such a position. In this way, the mechanical clock of the invention provides a means to rotate the clock itself into a position whereby the time displayed may be altered manually, and subsequently return the clock to its initial position.
In some embodiments the mechanical clock may additionally comprise a user interface switch. The interface switch may be operable in use to override the automatic winding operation of the winding mechanism. For example, in some embodiments the interface switch may be operable in use so that, when switched, the automatic winding mechanism is wound for a given length of time. This may be desirable as in certain situations a user may wish to demonstrate the operational use of the mechanical clock, or to test that the automatic winding of the mechanism is functioning correctly. In some embodiments the interface switch may be operable in use so that, when switched, the clock may alter its configuration, such as its position. This may be desirable in situations where a user may wish to move the position of the clock for a better viewing angle or in some embodiments such that a crown wheel is presented to the user for altering the time on the clock itself. In some embodiments the interface switch may be operable in use to disconnect the clock from the vehicle for removal from the vehicle. In such embodiments, the watch may be configured such that under the operation of the interface switch it is moved to a certain position, through rotational or translational movement to a position where it may be disconnected from the vehicle. In some embodiments the interface switch is operable in use to perform two or more of the above-mentioned tasks.
The user interface switch may comprise a push button, or a flick switch, for example. In embodiments wherein the interface stich comprises a button, the button may be operable in use to perform one or more of the above-mentioned tasks upon depression of the button for a set period of time, or for a set number of times consecutively. In embodiments wherein the interface switch comprises a flick switch, the switch may be operable in use to perform one or more of the above-mentioned tasks upon movement of the switch from a first position to a second position for a set period of time, or for a set number of times consecutively.
The clock may be mounted in a holder. The holder may comprise the user interface switch. The clock may rotate in the holder in order to actuate the winding mechanism, and rotation of the clock in the holder may be powered by the electrical system of the vehicle.
According to a second aspect of the present invention there is provided a vehicle comprising a mechanical clock in accordance with the first aspect of the present invention.
The mechanical clock may comprise any or all of the features of a mechanical clock of any one of the first to fourth aspects of the present invention as desired or appropriate.
In some embodiments the mechanical clock is positioned on or within a dashboard of the vehicle. In other embodiments the mechanical clock may be positioned on or within a centre console of the vehicle.
In order that the invention may be more clearly understood embodiments thereof will now be described, by way of example only, with reference to the accompanying drawings, of which:
Although not shown in the Figures, it is to be understood that the clock 2 is electrically connected to the electrical circuitry of the vehicle. In this way, the winding mechanism may be wound automatically via rotation of the clock 2 within the holder 4 which is powered by a battery within the vehicle, which may be the vehicle battery itself
The Figures illustrate the clock 2 in a number of different configurations and show the operational use of the clock 2.
It is envisaged that the clock 2 will rotate constantly for a set period of time, or for a set number of rotations, in order to wind the winding mechanism of the clock 2. Furthermore, this rotation of the clock 2 will be performed in a periodic manner, for example, every hour, in order to ensure that the clock 2 remains functional. This may be performed irrespective of whether the vehicle to which the clock 2 is connected is in use.
To ensure that the clock face 6 is returned to the position shown in
The sensor may additionally be used to check whether the clock 2 and/or clock face 6 is in the correct position during ‘normal’ use, i.e. when the winding mechanism is not being wound. This is illustrated figuratively in
The button 12 may additionally be operable to perform further tasks with regards to the operation of the clock 2. For example, depression of the button 12 may cause the clock 2 to rotate once through 360°. In this way, the winding of the winding mechanism may be undertaken ‘manually’ to either simply display this feature, or to check that automatic winding of the mechanical clock 2 is functioning correctly. Furthermore, the button 12 may also be operable, upon depression, to rotate the clock 2 with respect to the body 4 to a position whereby the clock 2 itself disconnects from the connected vehicle. This may be desirable to enable the clock 2 to be removed for servicing or cleaning, for example. It is envisaged that the button 12 may be used to perform two or more of the above actions and in such cases the length of time for which the button is depressed, or indeed the number of times the button is depressed consecutively may be different depending on which action is to be undertaken.
Whilst the clock 2 illustrated in the Figures is shown to rotate per se in other embodiments the clock 2 may have a rotatable clock face 6 which acts to wind the winding mechanism, the clock face being rotatably connected to a stationary clock body and/or the clock 2 may include an alternative or additional means to wind the winding mechanism, such as a winding key, for example.
The above embodiments are described by way of example only. Many variations are possible without departing from the scope of the invention as defined in the appended claims.
