Abstract
Abstract This locking device for holding a pivoting window, notably of a motor vehicle, in its closed, ajar or semi-open positions, comprising a torsion bar hinge along one side and on the opposite side said locking device, consists essentially of a three-lug member pivotally mounted about an axis parallel to said opposite side to the window frame, a first lug acting as a control lug, the second lug being substantially perpendicular to said first lug and adapted to retain the window ajar, the third lug acting as an intermediate locking lug driven with a moderate clearance and adapted to retain the window in its closed position, and resilient means normally urging said third lug in its locking position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
Device for locking a pivoting window in its closed position and in a partly open or ajar position, characterised in that it comprises resilient means for urging the window to its closed position, a three-lug locking member pivoted about an axis parallel to the plane of said window and comprising a control lug adapted when rotated to cause the simultaneous rotation of the one hand of a second lug adapted to retain the window in the ajar position, said second lug being directed substantially at right angles to said control lug, and on the other hand of a third intermediate locking lug driven with a moderate clearance, against which the window is pressed in the closed position, and a resilient member normally urging said locking member to its locking position.
Claim 2
Dependent Claim
130 words
Device for locking a pivoting window in its closed position and in a partly open or ajar position, characterised in that it comprises resilient means for urging the window to its closed position, a three-lug locking member pivoted about an axis parallel to the plane of said window and comprising a control lug adapted when rotated to cause the simultaneous rotation of the one hand of a second lug adapted to retain the window in the ajar position, said second lug being directed substantially at right angles to said control lug, and on the other hand of a third intermediate locking lug driven with a moderate clearance, against which the window is pressed in the closed position, and a resilient member normally urging said locking member to its locking position.
Claim 3
Dependent Claim
38 words
Locking device according to claim 1, characterised in that the resilient means for urging the window to its closed position comprises a torsion bar disposed along one edge of said window which is opposite to said locking member.
Claim 4
Dependent Claim
26 words
Locking device according to claim 1, characterised in that said resilient member comprises a spring blade bent twice substantially at right angles and in opposite directions.
Claim 5
Dependent Claim
34 words
Locking device according to claim 1, characterised in that said spring blade comprises an opening adapted to co-act with a heel formed integrally with said locking lug in the closed position of said window.
Claim 6
Dependent Claim
32 words
Locking device according to claim 1, characterised in that the lug adapted to set the window ajar comprises an integral heel adapted to co-act with the spring blade for releasing the window.
Claim 7
Dependent Claim
28 words
Locking device according to claim 1, characterised in that said locking lug comprises a projection engaged by said spring blade for locking the device in the ajar position.
Claim 8
Dependent Claim
27 words
Locking device according to claim 1, characterised in that said locking lug has formed therein a notch engageable by said spring blade in the window release position.
