Abstract
Abstract A locking system for safe doors of the type comprising a turnable handle or handwheel for operating one or more sets of bolts between a locked position, wherein the bolts project into the door rim, and an unlocked position, wherein the bolts are withdrawn from the door rim. The system is characterized by bolt-securing means in the form of locking pins adapted to be inserted, in the locked position of the bolt, into aligned bores formed through each bolt and through a wall of a fixed bolt housing block slidingly supporting the bolt during the displacement thereof between the locked and unlocked positions. The pins are displaced into their locking or inserted position immediately after the locking of the bolts during a continuous rotation of the handle.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A turnable handle or handwheel operated locking system for safe doors, comprising at least one set of bolts, each bolt being slidable within a fixed bolt housing block between locking and unlocking positions wherein the bolts project into, and are withdrawn from the door rim, respectively, a locking pin for each of said bolts extending normal to the bolt and being in axial alignment with an opening formed at a wall of the said block, a bore formed in the block parallel to the axial direction of said opening and said pin, the pin being slidably movable in said axial direction and being mounted onto a support member coupled, on the one hand, to the handle and, on the other hand, to the bolts of each bolt set for displacing the bolts into their projected and withdrawn positions, so that in the projected position of each bolt, its associated bore and opening become aligned with respect to each other and the pin becomes inserted through said opening and into said bore for securing the bolt in the locking position.
Claim 2
Dependent Claim
179 words
A turnable handle or handwheel operated locking system for safe doors, comprising at least one set of bolts, each bolt being slidable within a fixed bolt housing block between locking and unlocking positions wherein the bolts project into, and are withdrawn from the door rim, respectively, a locking pin for each of said bolts extending normal to the bolt and being in axial alignment with an opening formed at a wall of the said block, a bore formed in the block parallel to the axial direction of said opening and said pin, the pin being slidably movable in said axial direction and being mounted onto a support member coupled, on the one hand, to the handle and, on the other hand, to the bolts of each bolt set for displacing the bolts into their projected and withdrawn positions, so that in the projected position of each bolt, its associated bore and opening become aligned with respect to each other and the pin becomes inserted through said opening and into said bore for securing the bolt in the locking position.
Claim 3
Dependent Claim
21 words
The system as claimed in claim 1 wherein said support member comprises a rack whose teeth are meshed with a pinion.
Claim 4
Dependent Claim
59 words
The system as claimed in claim 2 wherein the support member forms a flat bar provided with a slot having a first section extending at an angle with respect to the said axial direction and a second section extending parallel to the said direction, the bolts being coupled to the bar by a guiding pin moveable within the slot.
Claim 5
Dependent Claim
24 words
The system as claimed in claim 3 comprising three sets of bolts and securing means, for the upper, side and bottom of the door.
Claim 6
Dependent Claim
24 words
The system as claimed in claim 4 wherein the rack of one set is coupled to the racks of the other sets through gearwheels.
Claim 7
Dependent Claim
30 words
The system as claimed in claim 5 further including a key-operated or combination lock having a projectable locking member adapted to arrest the slidable movement of one of said racks.
