Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
85 words
A signalling device comprising: A first member associated with one terminal of an electrical signalling apparatus circuit; A second member associated with another terminal of the apparatus; displaceable mounting means between the first and second members allowing relative movement therebetween; electrical actuating means installed between the members in a normal breaking position with respect to the said apparatus circuit; and means for making the said circuit upon an abrupt relative displacement of the members away one from the other to actuate the said apparatus circuit.
Claim 2
Dependent Claim
85 words
A signalling device comprising: A first member associated with one terminal of an electrical signalling apparatus circuit; A second member associated with another terminal of the apparatus; displaceable mounting means between the first and second members allowing relative movement therebetween; electrical actuating means installed between the members in a normal breaking position with respect to the said apparatus circuit; and means for making the said circuit upon an abrupt relative displacement of the members away one from the other to actuate the said apparatus circuit.
Claim 3
Dependent Claim
24 words
The device as claimed in Claim 1 comprising further means for adjusting the effective amount to the relative movement for making the said circuit.
Claim 4
Dependent Claim
48 words
The device as claimed in Claim 2 wherein one of the members is adapted to be affixed to the accelerator pedal of a vehicle and the other movable member is adapted to be pressed by the accelerator pedal operating foot of the driver against the said displaceable means.
Claim 5
Dependent Claim
18 words
The device as claimed in Claim 3 wherein the said signalling apparatus includes the brakelights of the vehicle.
Claim 6
Dependent Claim
123 words
The device as claimed in Claim 4 wherein the first and the second members form a hollow housing within which there is defined an air chamber having an air inlet opening at one side and a displaceable wall portion at its opposite side, constituting the said other member, a lightweight, freely floating conductive metal flap being provided at the vicinity of the air inlet, the arrangment being such that during normal, pressed position of the accelerator pedal, the flap is kept at a small distance from the air inlet, and upon an abrupt release of the pedal, the flap becomes sucked by a sub-pressure momentarily prevailing within the air chamber, and engages a portion of the air inlet thereby making the said circuit.
Claim 7
Dependent Claim
66 words
The device as claimed in Claim 5 wherein the housing comprises a flange portion with a central opening provided with a projecting rim therearound, a bellows seated on top of the flange around the opening, a plug member threadably mounted below the opening and supporting the said opening rim, and electrical connections for closing the said circuit by contact between the flap and the said rim.
Claim 8
Dependent Claim
24 words
The device as claimed in Claim 6 comprising a switching device for enabling the said circuit only upon complete displacement of the said members.
Claim 9
Dependent Claim
46 words
The device as claimed in Claim 4 wherein the first and second members form a housing having one wall thereof movable relative to another immovable wall, electromotive generating means comprising an induction coil and a magnetic core being associated each with one of the said walls.
Claim 10
Dependent Claim
17 words
The device as claimed in Claim 8 wherein one wall is pivotally coupled to the other wall.
Claim 11
Dependent Claim
16 words
The device as claimed in Claim 8 wherein the coil is fixed to the immovable wall.
Claim 12
Dependent Claim
16 words
The device as claimed in Claim 8 wherein the coil is fixed to the movable wall.
