[0001] The present invention concerns a lock for the automatic closing of doors, main doors,
shutters and similar, of the kind that determines a block without any intervention
by the user.
[0002] In the art, European patent EP A 099 292 is known in which a safety locking device
for doors is shown, presenting the following features and functionalities:
- locking of the latches only at the end of the run, while in the intermediate positions
said latches are free and therefore may be opened;
- it is necessary to use the key for unlocking the lock of the latches, from inside
as well as from outside, so that only after the use of the key and by means of a handle
said latches will be taken out of their seats;
- it is necessary to use springs and counterweights for supplying a considerable force
for operating the system, braked by the presence of contrast springs;
- the functionality of the click or slide of the lock, which has no other function than
the one of determining the outlet of the latches, as it remains inside withour reaching
the outlet position;
- the need of addition of a conventional lock, as the invention consists of a device
that causes the movement of a group of locks.
[0003] The lock according to the present invention solves the problem of performing, at
each closing, the automatic insertion of safety means by means of purely mechanical
controls making use of the force of gravity acting on the single components.
[0004] Such a problem is solved by an automatic closing lock according to claim 1.
[0005] The advantages of the lock according to the present invention are many and considerable:
- it determines the automatic closing of the bolt due to the force of gravity;
- it allows the opening from inside by means of a handle;
- from the outside, due to the particular shape of the key, the same may be inserted,
through an eyelet much smaller than the safety cylinder, and the opening is possible
in whatever position the lock mechanism is placed at the moment of use.
[0006] The lock accoding to the present invention will be described more in detail hereinbelow
according to the enclosed drawings, in which a preferred embodiment is shown.
- Figure 1
- shows a plan view of the automatic closing lock with the components in the position
cf open door.
- Figure 2
- shows the lock in the closing step, with the spring latch nearly completely returned.
- Figure 3
- shows the outlet position of the bolts CA in a door being already in safety conditions.
- Figures 4 and 5
- show, in an exemplified form, the single elements of the lock.
[0007] The figures show an automatic closing lock, comprising the following elements:
- a box and cover 1
- a spring latch 2
- a slide 3
- a bolt connecting rod 4
- a rotating bolt 5
- a safety cylinder 6
- a pinion 7
- a gear segment 8
- a lever 9 with square joint
- a connecting rod 10 with an eyelet
- a lever 11 for the return of the spring latch
- a return spring 12
- a gear stop 13
- a support for fixing cylinder 14
- a spring 15
- a cylinder 16
- a pin 17 with a shaped end blind hole
- a pin 18 with enlarged base blind hole
- a key 19, having such a shape as to allow the protection of the lock behind an apposite
autotempering steel plate.
[0008] Relating now to the details of the figures for what concerns the functioning of the
closing, when the door comes near the wing the spring latch 2 enters in the lock and
releases and frees, by means of the inclined plane H resting in F, the slide 3. Said
slide, due to the force of gravity, performs the downwards movement until the lower
dead point cuasing, due to the connections and to the connecting rod of the rotating
bolt, the insertion of the bolts in the respective seats and the operation of stop
13 by means of a push that D performs onto Q; in the same time, the insertion of the
lock stop takes place through the three stop steps of B on P, that stops the opposite
sliding of said slide 3 and of all elements connected thereto.
[0009] At the same time, said spring latch 2, being pushed by said lever 11 due to said
spring 12, enter the apposite hole provided in the wing of the door.
[0010] For what concerns the functioning of the opening from the outside, through the rotation
of the key 19 the movement is transmitted to said pinion 7 inserted in the gear segment
8; this latter one, by means of its pin M, acts on the upper side cf hole C making
rise the slide 3; by moving, said slide 3 causes the drawing of bolts CA and, performing
the last part of its run, releases stop 13 through a push of E on S and, by a push
of element G onto part I of the return lever 11, moves the spring latch 2 inside the
lock by means of hole N inserted into pin 0.
[0011] The opening from the inside occurs by rotating the handle or knob, without using
the key. The lever 8, having its fulcrum by means of a pin Y inserted therein, is
provided with a square joint at the end of said pin, where the handle through which
said lever may rotate is jointed. Said lever is provided, at the opposite end of the
fulcrum, with a pin K that connects it to the connecting rod 10 with eyelet so that,
during the rotation of the handle, the movement of the connecting rod takes place
and, through the eyelet hooked to pin M, the movement is brough back to the gear segment,
thus causing the opening process as already described for the key.
[0012] A main feature of the lock according to the present invention consists in that the
pinion is made free to rotate according to any movement of the lock mechanism by means
of two springs 15, a cylinder 16, a pin with an enlarged end blind hole 18 and a shaped
end blind hole 17. The latter one transfers the rotating movement of the key 19 to
pinion 7 due to an obliged joint that occurs, between pin 18 and pinion 7, in whatever
position the mechanism of the lock is found in the moment the key is used.

with a first abutment (F) and a second abutment (D), said slide (3) being blocked
in a first position by a spring latch (2) provided with a plane engaging the first
abutment (F) of the slide, and released by the spring latch (2) when the door gets
near to the wing, so that the slide can slide downwards due to gravity, inserting
the bolts (CA) into their respective seats, and moving a connecting rod (4) of a further
bolt (5) as to insert the bolt (5) into its respective seat, while the second abutment
(D) of the slide abuts against a stop (13), characterized in that the slide (3) is
further provided with a blocking element (B) having three steps which, when the slide
is released by the spring latch (2) and reaches its lower position, are engaged by
the teeth of a gear segment (8), connected to the slide (3) in such a way that sliding
of the slide (3) involves a rotation of said gear segment (8), as to block the slide
and all elements connected thereto, the spring latch (2) being then pushed by a lever
(11) and a spring (12) into a suitable hole provided in the wing, and in that the

rise the slide which, by moving, causes first the drawing of the bolts (CA) and, in
the last part of its run, releases the stop (13) by means of the push of a third abutment
(E) of the slide on a portion (S) of the stop (13) and, by action of an element (G)
of the slide (3) onto a part (I) of a return lever (11) provided with a hole (N) jointed
to a pin (O) of the spring latch (2), moves the spring latch inside the lock.
3. An automatic closing lock according to claim 1, characterized in that the opening
of the lock from inside is obtained by rotation of a handle, wihout any use of a key,
