Locking device for movable leaves such as window panes

Claim 2

In a device for locking a movable leaf such as a window pane to a fixed frame, comprising a main lock having a catch mounted on the leaf and a staple fixed in oppositely facing relation on the frame, a handle mounted on the leaf and adapted to control the catch and at least one auxiliary lock; the improvement comprising motion-transmission means carried by said frame and connected on the one hand to said auxiliary lock and on the other hand to connection means mounted within said staple and adapted to be operated by said catch, whereby said auxiliary lock is remotely operated upon actuation of said handle.

Claim 3

A locking device as claimed in claim 1, said connection means comprising a slide block mounted within the staple, said motion-transmission means being connected to said slide block and to a rocking latch which forms part of the auxiliary lock.

Claim 4

A locking device as claimed in claim 2, and means for returning the rocking latch to the open position, the main lock having a staple engagement slot having a boss for arresting the catch in the closed position.

Claim 5

A locking device as claimed in claim 2, said slide block having a shaped recess for accommodating the extremity of the catch.

Claim 6

A locking device as claimed in claim 1, said motion-transmission means comprising a sheathed sliding cable which is connected to the movable member of the auxiliary lock.

Claim 7

A locking device as claimed in claim 1, said motion-transmission means being disposed within a rebate formed in the frame.

Claim 8

A locking device as claimed in claim 2, each rocking latch having a separate restoring member comprising a spring.

Claim 9

A locking device as claimed in claim 2, said motion-transmission means comprising a link-rod system.

Claim 10

A locking device as claimed in claim 8, and a single spring mounted within the staple and compressed by the slide block during the locking action for returning said rocking latch to the open position.

Claim 11

In a device for locking a movable leaf such as a window pane to a fixed frame, comprising a main lock having a catch mounted on the leaf and a staple fixed in oppositely facing relation on the frame, a handle mounted on the leaf and adapted to control the catch and at least one auxiliary lock; the improvement comprising motion-transmission means carried by said frame and connected on the one hand to said auxiliary lock and on the other hand to a slide block mounted within said staple and adapted to be operated by said catch, whereby said auxiliary lock is remotely operated upon actuation of said handle.

Claim 12

In a device for locking a movable leaf such as a window pane to a fixed frame, comprising a main lock having a catch mounted on the leaf and a staple fixed in oppositely facing relation on the frame, a handle mounted on the leaf and adapted to control the catch and at least one auxiliary lock; the improvement comprising motion-transmission means carried by said frame and connected on the one hand to said auxiliary lock and on the other hand to a slide block mounted within said staple and adapted to be operated by said catch, whereby said auxiliary lock is remotely operated upon actuation of said handle.

Claim 13

A device as claimed in claim 1, for locking a leaf which is pivotable selectively about a horizontal axis and about a vertical axis, wherein a first set of auxiliary locks and a second set of auxiliary locks are disposed on a horizontal side and on a vertical side of the frame respectively, the auxiliary locks of each set comprising hinge means defining one of said axis and having a movable member which is connected to said motion-transmission means carried by the frame, and wherein means are provided in the main lock for defining two open positions and a closed position thereof, whereby when the main lock is in one of said open positions the auxiliary locks of the first set are in a closed position and the auxiliary locks of the second set are in an open position so that the leaf can be pivoted about said horizontal axis and when the main lock is in the other of said open positions the leaf can be pivoted about said vertical axis.

Claim 14

A device as claimed in claim 10, for locking a leaf which is pivotable selectively about a horizontal axis and a vertical axis, wherein a first set of auxiliary locks and a second set of auxiliary locks are disposed on a horizontal side and on a vertical side of the frame respectively, each auxiliary lock comprising two hinge components defining one of said axis, one component being secured to the leaf and the other component being secured to the frame, and a movable pin slidably mounted in the hinge component which is secured to the frame so as to cooperate with the hinge component which is secured to the leaf, said movable pin being connected to said motion-transmission means, and wherein the staple of the main lock has a cover plate in which are formed two recesses and a boss projecting therebetween toward the interior of the staple so as to define two open positions and a closed position of the main lock respectively, the catch carrying a stud which is engageable into a bore formed in said slide-block and the connections being such that the forcible engagement of the catch in the closed position of the main lock between said boss and the slide-block causes the leaf to be applied under pressure against a flexible seal which is disposed between the leaf and the frame, whereby when the main lock is in one of said open positions, the auxiliary locks oF the first set are in a closed position and the auxiliary locks of the second set are in an open position so that the leaf can be pivoted about said horizontal axis, and when the main lock is in the other of said open positions, the leaf can be pivoted about said vertical axis.

Claim 15

A locking device as claimed in claim 12, wherein the catch of the main lock is integral with a rack housed in a support plate on the leaf and engaging with a toothed sector which is secured to the handle.

Claim 16

A locking device as claimed in claim 12, wherein, in the closed position of the main lock, the movable pin of each auxiliary lock is engaged to half the distance of travel within the hinge component which is secured to the leaf, in one of said two open positions of the main lock the movable pin of each auxiliary lock of one of said sets is fully engaged in said hinge component and in the other of said open positions of the main lock said movable pin is fully disengaged from the hinge component.

Claim 17

A locking device as claimed in claim 12, wherein an additional locking member connected to said motion-transmission means is provided for engaging a crossmember which is secured to the top portion of the leaf when the main lock is in the closed position.
