Full Text	This invention relates to "a theft proof alarm system for a two-wheeler against any illegal mobilisation thereof by retracting the centre-stand and comprising the same for the two-wheelers". In any known two-wheeler, there is a normal practice done by putting the centre-stand {with on-stand condition) for vehicle parking. The vehicle will be released from the on-stand position to the off-stand position by retracting the centre-stand for any mobilization. Even when the vehicle was steering locked against the theft-occurrence during parking, there is the possibility to mobilize any known vehicle by the thief or thieves by normally retracting or relieving the centre-stand from the ground and then lifting any one of the wheels. The mobilization of any known vehicle is possible only after retracting the centre-stand of the locked vehicle. It has not been absolutely possible so far to prevent this kind of theft or the possibility thereof, even in the vehicle with steering locked condition. According to this invention, a theft proof alarm system for a two-wheeler against any illegal mobilisation thereof by retracting the centre-stand and comprising the same for the two-wheelers, comprises a limit-switch provided, spring-loaded and rigidly connected to the centre-stand-bracket as a part of the vehicle, said switch is operatively connected between an electric-power source and a theft alarm system wherein said limit-switch is loaded by said centre-stand by means of switch-off condition at on-stand position, against the said spring which is provided in said limit-switch to normally release the said limit-switch for switch-on condition so as to close the electric-power circuit to operate the theft alarm system as a caution against the theft occurrence, only when the said centre-stand was retracted to off-stand position for the purpose of any illegal mobilization as the theft, there is also a manual switch integrally provided with •&> known ignition switch with one more theft-lock mode and operatively connected between said electric-power source and said theft alarm system in series with said limit switch so as to switch-on or to activate the said alarm system only when the centre-stand was retracted for any mobilization as the theft and only after the rider switched the said manual switch with theft-lock-on condition after ignition-off or with steering-locking by the ignition key. The invention will now be apparent from the following non-limitative description with reference to the accompanying drawings, in which; FIGURES 1 and 2 respectively show pictorial and orthographic views of an arrangement comprising a limit-switch connected to centre-stand-bracket and its mounting bracket as a part of a two-wheeler during on-stand condition of the centre-stand according to this invention; FIGURES 3 and 4 respectively show pictorial and orthographic views of the above said arrangement during off-stand condition of the said centre-stand; FIGURE 5 shows schematic circuit diagram of the arrangement of said limit-switch connected to the centre-stand, theft alarm system, electric-power source and theft-locking switch; Referring to FIGURES 1 to 4, according to this invention, there is provided a limit-switch 1, which is spring-loaded and rigidly connected to the centre stand-bracket 2 as a part of the vehicle. The said switch 1 is also operatively connected between an electric-power source 4 and a theft alarm system 5 through electrical cables 5A as shown in Figure 5A. The said limit-switch 1 is kept in switch-off condition by means of the centre-stand 3 pressing over the said switch 1 during its on-stand position as shown in Figures 1 and 2.
