Claim 1
Independent Claim
128 words
A tire abnormal condition alarming system for a vehicle comprising: a remote control device including: a signal receiver for receiving receive a door unlocking or locking aerial propagation signal from an operating key; a door locking mechanism operated according to the signal reception of the signal receiver, to unlock or lock a door; and a signal transmitter coupled to a tire of the motor vehicle, the signal transmitter detecting an abnormal condition of the body of revolution to transmit an abnormal condition detection signal as an aerial propagation signal to the signal receiver, alarming means for performing a warning operation to inform the occurrence of the abnormal condition with the vehicle by operating the signal receiver upon reception of the abnormal condition detection signal from the signal transmitter.
Claim 2
Dependent Claim
112 words
A tire abnormal condition alarming system for a vehicle as claimed in claim 1, wherein the signal transmitter including: at least two abnormal condition detecting switches turned off upon detection of an abnormal condition of the body of revolution; a DC source, one of terminals of the DC source being grounded through one of the abnormal condition detecting switches; a switching element with a control terminal which is grounded through the other abnormal condition detecting switch and is connected through bias means to the other terminal of the DC source; and an oscillator for outputting an abnormal condition detection signals as an aerial propagation signal when the switching element is turned on.
Claim 3
Dependent Claim
78 words
A tire abnormal condition alarming system for a vehicle as claimed in claim 2, wherein the abnormal condition detecting switch includes: a plurality of electrically conductive brackets which are connected to a body casing and are secured to the hub of a tire wheel with hub nuts through insulating layers interposed between the tire wheel and the brackets, wherein the abnormal condition detecting switches is held turned on with the brackets electrically in contact with the hub nuts.
Claim 4
Dependent Claim
28 words
