Description
VEHICLE ELECTRONIC ANTITHEFT DEVICE
TECHNICAL FIELD The present invention relates to a vehicle electronic antitheft device.
BACKGROUND ART
Electronic antitheft devices for two-wheel vehicles, in particular bicycles, are known to comprise an outer casing fittable to the bicycle frame and housing an electronic alarm circuit for driving a sound emitting device.
In addition to being easily tampered with or even removed from the bicycle frame, known antitheft devices of the above type are also bulky.and unsightly.
DISCLOSURE OF INVENTION
It is an object of the present invention to provide a vehicle antitheft device designed to overcome the aforementioned drawbacks typically associated with known devices.
According to the present invention, there is provided a vehicle electronic antitheft device comprising:
- an outer casing for protection and support;
- an electronic microprocessor circuit housed in said casing;
- acoustic signaling means controlled by said electronic circuit and fitted to said casing; and
- vibration sensing means cooperating with said electronic circuit, for detecting displacement of said vehicle and activating said acoustic signaling means when said electronic circuit is enabled; characterized in that said outer casing is defined by a tubular portion of said vehicle.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be described with particular reference to the accompanying drawings, in which: Figure 1 shows a bicycle featuring an antitheft device in accordance with the teachings of the present invention;
Figure 2 shows a larger-scale view of the Figure 1 antitheft device; Figure 3 shows a logic operating diagram of the
Figure 2 antitheft device.
BEST MODE FOR CARRYING OUT THE INVENTION Number 2 in Figure 1 indicates a bicycle, in particular a Mountain Bike, featuring an antitheft device 1 in accordance with the teachings of the present invention.
As shown in Figure 2, device 1 comprises an outer casing for protection and support, defined by tube 4 of
the saddle of bicycle 2; an electronic microprocessor circuit 6 housed in tube 4; and a piezoelectric transducer 8 controlled by electronic circuit 6 and fitted to tube 4. More specifically, in the example shown, tube 4 comprises a cylindrical tubular portion 4a housed partially inside a tube of frame 10 of bicycle 2; and a tubular end portion 4b smaller in diameter than portion 4a and supporting the bicycle saddle 13 (shown by the dotted line in Figure 2).
Tube 4 defines a cylindrical cavity 15 coaxial with an axis 17, and communicating externally through an end opening 20 in tubular portion 4a and an end opening 22 in portion 4b. Tubular end portion 4b houses an inner retaining ring 24 supporting piezoelectric transducer 8 facing opening 22.
Electronic microprocessor circuit 6 is formed on a rectangular printed circuit extending along axis 17, and presents a first end portion 6a adjacent to transducer 8.
Tube 4 also houses a device for supplying electronic circuit 6 and comprising two (or four) 1.5 V batteries 25 connected in series along axis 17 and located between a second end portion 6b of circuit 6 and a cap 27 closing opening 20.
Electronic circuit 6 is also connected to a vibration sensor 30 for detecting displacement of
bicycle 2 and activating circuit 6 as described later on.
Vibration sensor 30 presents a movable element, e.g. a metal ball (not shown) , which is moved from one (or more) positions of stable equilibrium to activate one (or more) electric contacts when tube 4 is moved and bicycle 2 displaced.
Electronic circuit 6 also presents an on/off device comprising a known electronic key 33 which is inserted inside a jack 35 fitted to tube 4 and connected by cables 37 to circuit 6.
Figure 3 shows a logic operating block diagram of microprocessor circuit 6.
As shown in Figure 3, operation of circuit 6 commences with a block 100 in which circuit 6 is in standby mode awaiting turn-on of device 1 by removing electronic key 33 from jack 35, and which, when key 33 is removed, goes on to block 110.
Supply to circuit 6 is normally cut off by electronic key 33 which, when inserted inside jack 35, cuts off an electric contact (not shown) to disconnect circuit 6 from supply device 25 and so prevent circuit 6 from drawing current when idle.
Block 110 provides for testing ' batteries 25 supplying circuit 6; and, if the voltage supplied by batteries 25 is below a memorized threshold value (e.g.
5 V in the case of a supply device comprising four 1.5 V batteries) , block 110 goes on to block 120 (LOW
BATTERY) . Conversely, block 110 goes on to block 130.
Block 120 provides for emitting an acoustic signal (BEEP) to indicate the low voltage of batteries 25, and then goes on to block 130. Block 130 provides for memorizing the state of the sensor, and more specifically for memorizing the position of the movable element (not shown) of vibration sensor 30 if this is a movable element type.
Block 130 is followed by a block 140 in which the present position of the movable element (not shown) of vibration sensor 30 is compared with the position memorized in block 130. If the memorized position corresponds with the present position (no vibration) , block 140 remains in standby mode. Conversely (vibration detected by sensor 30) , block 140 goes on to block 160 which determines whether a key 33 is inserted in jack 35 and whether the resistive value of key 33 equals a memorized (valid key) reference value. In the event of a positive response (key inserted and valid) , block 160 goes back to block 100; conversely (no key inserted, or inserted but not valid), block 160 goes on to block 165.
Block 165 provides for activating transducer 8 which emits a high-intensity acoustic signal for a predetermined length of time, after which, block 165 goes back to block 130.
The advantages of antitheft device 1 according to the present invention will be clear from the foregoing description.
Firstly, any possibility of device 1 being tampered with or removed is prevented by housing it inside a part of the bicycle (tube 4) which, by virtue of its function, is structurally strong and difficult to damage.
Secondly, device 1 in no way impairs the appearance of the bicycle by virtue of being housed entirely inside the bicycle itself.
Thirdly, device 1 is extremely compact, provides for fast, troublefree assembly, and is easy to turn on and off.
Clearly, changes may be made to antitheft device 1 as described and illustrated herein without, however, departing from the scope of the present invention. In particular, the outer casing may be defined by a tubular portion of the handlebar 40 (Figure l) of bicycle 2, or by a tubular portion 10a of frame 10 defining an inner cavity (not shown) in which to house circuit 6, transducer 8 and batteries 25. Device 1 may be turned on using a remote-control microwave transmitter (not shown) for transmitting control signals to a receiving circuit (not shown) connected to circuit 6.
And the alarm generated by block 165 of device 1 may also activate a transmitter (not shown) for transmitting an alarm code to a receiver (not shown) housed in key 33.
