Abstract

An electric or mechanical lock with manual or automatic leaf opening; in the region where an internal spring (10) acts, it is possible to arrange a tool (20) selectively in one of a plurality of seats (13, 14), even when the lock is already installed, interfering with the stroke of the arms (11, 12) of the spring (10) and being adapted to engage one of the arms (11) of the spring (10) in receptacles (A, B) of the latch (4). Once opening enabling has occurred, when the arm (11) is in a first receptacle (A), the spring (10) is not elastically tensioned and applies no torque to the latch (4), this being the setting for manual opening of the leaf; when the arm (11) is in a second receptacle (B), the spring (10) is elastically tensioned and applies a torque to the latch (4) that is suitable to move it away from said post-equipped selvage (2), this being the setting for automatic leaf opening.

Description

Electric or mechanical lock with opening manual or automatic swing.

Field of the Invention

The present invention relates to a lock with manual or automatic swing opening, in particular for gates and entrance doors.

Conventional electronic locks, a Once they have received the signal that enables the opening, they keep a mutual and constant alignment of the latch on the edge until the application of an external action, although the latch has shifted out of the edge.

This external action may be the push that give a person the door you want to go through the opening, but it can also be the action of a mechanical device or electromechanical, designed to allow automatic opening of the swinging

In conventional locks, when produces the slack to open the lock, the swing is not usually open automatically, that is, without going to other elements external to said lock; there are constructive solutions associated with the removal of the latch towards the position of opening, the action applied between the lock frame and the edge of a properly planned body, generally driven by an elastic force, which opens the swing automatically.

In the locks provided with a cooperation ratchet type of the part that is rigidly coupled to the with the edge of a pole provided (such as the one disclosed in Italian Patent Application BO2001A000033 or in WO 02.059.443 A in the name of the same CISA applicant S.p.a.), two different pulse reactions can occur opening enable.

In the first case, the enabling pulse that triggers the electromagnet forces the decoupling action to pressure of the part rigidly coupled to the swing with respect to the edge endowed with a pole; said pressure action forces automatically opening the swing, since the partial rotation of the ratchet mechanism from the closed position to the open position tends to distance the mechanism from the fixed edge with pole.

In the second constructive solution, in case of provide the enabling impulse that triggers the electromagnet, the ratchet mechanism remains stationary in the position of closing and its turn towards the open position is only due to a external action (for example the push to open produced by the person who wishes to pass through the opening).

Anyway, with the locks available currently on the market, the installer cannot select the desired type of opening and change its status with time when the Lock is already installed.

The purpose of the present invention is to in obviating the aforementioned inconveniences and satisfying the mentioned requirements providing an electric lock or mechanical with manual or automatic opening of the swing in which the reaction that occurs after the impulse can be established opening enable.

Within this purpose, an objective of the present invention is to provide a lock that is simple, relatively easy to provide, in practice, safe to use, efficient and cost effective relatively small

The purpose and other objectives that will be set manifest more clearly are achieved below by the electric or mechanical lock according to claim 1.

Other features and advantages of this invention will become more clearly apparent from the following detailed description of an embodiment preferred but not exclusive to an electric or mechanical lock with manual or automatic opening of the swing according to the invention, illustrated by way of non-limiting example in the drawings Attachments, in which:

Figure 1 represents a side view in partially truncated section, according to the longitudinal central plane, of a rigidly coupled ratchet type coupling set to the swing of an electric or mechanical lock with opening manual or automatic according to a preferred embodiment of the invention, in the position where the lock is open

Figure 2 represents a side view in partially truncated section, according to a longitudinal central plane of a rigidly coupled ratchet type coupling set to the swing of an electric or mechanical lock with opening manual or automatic according to a preferred embodiment of the invention, in the position where the lock is closed;

Figure 3 represents a projection view axonometric of an edge provided with a pole to couple a ratchet type coupling assembly of an electric lock or mechanics according to a preferred embodiment of the invention;

Figure 4 represents a side view in partially truncated section, according to a longitudinal central plane of a rigidly coupled ratchet type coupling set to the swing of an electric or mechanical lock with opening manual or automatic according to a preferred embodiment of the invention, in the configuration for manual opening;

Figure 5 represents a side view in partially truncated section, according to a longitudinal central plane of a rigidly coupled ratchet type coupling set to the swing of an electric or mechanical lock with opening manual or automatic according to a preferred embodiment of the invention, in the configuration for automatic opening.

Referring to the drawings, the number of reference 1 generally designates a type coupling assembly ratchet rigidly attached to the swing of a lock electrical or mechanical with manual or automatic opening according to a preferred embodiment of the invention and the number of reference 2 generally designates the corresponding edge provided with post; the set 1 is fixed on the swing and the edge 2 it is fixed on the fixed stop, and the two parts are coupled to Lock the swing.

The coupling assembly 1 comprises a outer envelope 3, inside which pivot a latch 4 and a seesaw 5; when the lock is open, the surface convex 6 of latch 4 is adjacent to concave surface 7 of the rocker 5, and the two parts can freely move a with respect to the other.

When the lock is closed, the flat surface 8 of latch 4 is bound against the lug of retention 9 and this obligation prevents the rotation of the latch 4.

An angularly actuated spring 10 acts on latch 4 and rocker 5, respectively with its arm 11 on the latch 4 and its arm 12 on the outer envelope 3.

In envelope 3 two seats are provided 13 and 14 fit to accommodate a tool, which consists substantially in a metal cylinder 20 whose diameter is suitable to insert into seats 13 and 14.

The function of the metal cylinder 20 consists of allow to lock the lock: also, for this purpose, you can use conventional tools with shape features and Similar size (screwdriver, punch, etc.).

When metal cylinder 20 is inserted into the first seat 13 interferes with the movement of the arm 11 of the spring 10, thus preventing its turn clockwise beyond of the point of contact between arm 11 and said tool; from in this way, the arm 11 of the spring 10 can move under pressure from the position identified by receptacle A of latch 4 to the position identified by receptacle B.

The spring 10 torque is applied to latch 4 by the action of arm 11 cooperating with receptacle B, and the action of the spring 10 is intense, since in the position imposed in this way, the spring is tensioned.

Once the opening is enabled, therefore, the set 1 ejects the edge 2, since inside the envelope 3 rotates rocker 5, placing its retaining lug 9 under the flat surface 8, and the latch 4, released, rotates in clockwise direction by spring action 10. When the tool acts on the first seat 13, is conferred on the lock, and therefore to the swing, the characteristics of a automatic opening lock.

When the tool is introduced in the second seat 14, rigidly engages the intersection point of the two spring arms 10, since it has an inner position with regarding their turns; in this way, arm 11 of spring 10 is allowed to move under pressure from the position identified by the receptacle B of the latch 4 to the position identified by receptacle A.

The spring 10 torque is applied to latch 4 by the action of arm 11 cooperating in receptacle A; this action is insignificant, since practically the spring 10 is not tense.

Once the opening is enabled, therefore, the set 1 remains in cooperation with edge 2, while the rocker 5 rotates inside the envelope 3, displacing its retaining lug 9 below the flat surface 8, and the latch 4 remains stationary, since spring 10 does not act with its arm 11 to turn it, thus expelling the edge 2. When the tool acts in the second receptacle 14, it is conferred on the lock, and therefore to the swing, the characteristics of a manual opening lock.

It has been shown that the invention reaches the purpose and objectives pursued.

The invention conceived in this way is susceptible of numerous modifications and variations, all of them are within the scope of the claims attached.

For example, others can be provided seats to house the tool, in order to make the Lock be more versatile. A third seat on the rocker 5, when said rocker is in the closed position, it could in fact close it in position: in the case of some doors secondary, there would be the possibility of disabling the operation of the lock when closed constantly in the closed condition, and to recover its operation, where appropriate, moving the tool from said third seat to one of The first two seats.

When the technical characteristics cited in any of the claims are followed by signs of reference, said reference signs are included only to facilitate the understanding of the claims and how consequently said reference signs have no effect limiting in the interpretation of each of the elements identified by way of example by means of said signs of reference.
