Description

Reversible Clutch Mortis Lock

The present invention relates to a reversible clutch mortise lock which allows the operation of the lock to be changed quickly and easily so that the outer handle behaves the same as the inner handle and vice versa.

The lock, which is the subject of the present invention, is applicable to the lock manufacturing industry, in particular to a security zone or door lock for entry and exit.

At present, a mortise lock of the type used to allow only authorized personnel to pass through has the handle of the lock moved in the non-engaged position without actuation of the latch (thus cannot open the door); On the other hand, when in the engaged position (since a cord, key or other system is introduced to operate the clutch), the handle can be rotated so that the latch moves and thus has a clutch mechanism to open the door.

It should also be taken into account that the operation of the handle depends on the position of the handle relative to the interior of the room.

In other words, the handle on the outside of the door (meaning a handle in a corridor or distance) means that the handle is always decoupled (and therefore the latch does not work when rotated) and the correct key (code, card, etc.) Is engaged only when is introduced and operates so that the latch can be activated when the handle is rotated.

On the other hand, when the handle is on the inside of the room, the operation always causes the latch to operate when the handle is rotated to allow it to exit the room (eg in a hotel) without introducing any keys.

The operation of the handle is reversed depending on whether the door opens to the right or left. Thus, in order to install a series of locks on a building, it is necessary to have two types of locks (some open to the right and other to the left to meet the operating characteristics described in both paragraphs above), or There is a need to have a system that can change the internal behavior of the system, resulting in supply errors and increased costs (since a certain number of two locks must be provided for the building to be installed).

Several documents are known that disclose locks similar to the locks of the present invention. Among the known documents, it is possible to quickly install concentrically shaped parts in the inner or outer parts of the lock, which are each sequentially joined to the shaft of the handle, thereby making the outer handle behave as the inner handle and vice versa. It is worth mentioning the document US2010 / 0263418 A1, which discloses a mortis lock with a reversible clutch comprising a part that enables a simple manner.

Also known is the document US2003 / 0127864 A1 which relates to a mortise lock which can be locked or unlocked due to an internal clutch locking mechanism. The locking mechanism includes a housing, a latch extending from the housing, and having an extended position and a retracted position. The lock further includes a pushing element for pushing the latch toward the extended position. The locking mechanism includes means for transferring movement from the latch to the retracted position.

In addition, the present applicant discloses a clutch device in an electric mortise lock having an emergency function, which means that it can be always open from the inside and from the outside, thus requiring a clutch of a certain type to enable this opening. The document ES2350218 A1 is known. In this document, the clutch device does not offer the possibility that the lock is reversible, so that the lock is different from the lock of the present invention.

Also known is the document ES2326482T3, which discloses a lock with controllable handle actuation. The lock in this document is intended to provide a solution that offers a wide range of possibilities for the installation and use of the door lock so that the lock can always be used from one side of the door and the use from the other side can be selectively controlled. In this document, the casing of the lock when installed in the door must be convertible so that it can be used in the door regardless of the direction of rotation of the door. In addition, in this lock, changes made in the casing can be made as simple and easy as possible without opening the lock casing by means of the installation arrangement.

Finally, Applicant also knows document ES2498892B2, which discloses a tilt clutch lock with springs of elastic accumulation that allow a change to be made such that the outer handle behaves like the inner handle and vice versa.

None of the documents known to the applicant provide security guarantees against unwanted manipulation of the locks such as those provided by the locks disclosed herein.

The present invention described includes a reversible clutch mortise lock comprising a center follower, a first side follower introduced into a center follower on one side of the center follower, and a second side follower introduced into a center follower on an opposite side of the first side follower.

Locks that are the subject of the present invention include a plurality of components, which are described individually below, and also how they interact with each other for the correct operation of the locks. In addition, the lock of the present invention includes an outer casing 1 which receives the components of the lock and also provides a surface on which some components of the lock are at least partially fastened.

The lock of the present invention comprises a central follower 2 for actuating the latch 3 of the lock; The center follower 2 is symmetrical with respect to the plane passing through its center and comprises a central hole 4 parallel to the plane of symmetry and two side housings 5 on the side of the plane of symmetry.

In the center hole 4 of the center follower 2, the lock which is the object of the present invention constitutes two curved holes 8 inside the center hole 4, and is also centered with respect to the side of the platen 7 itself. It has the platen 7 which divides a hole into two parts.

The lock of the present invention also comprises a first side follower 9 and a second side follower 10 arranged in the central hole 4 of the center follower 2 with respect to the side of the platen 7.

Each side follower (9, 10):

Circumferential opening 11,

Circumferential protrusion 12,

A central rectangular hole 13 into which the shaft of the handle 19 for the door in which the lock is arranged is introduced;

2 through holes (14),

A first cylindrical projection 6 around the central rectangular hole 13 in the contact surface with the platen 7, which facilitates positioning and rotation of the central follower 2 relative to the side followers 9, 10, And

A second cylindrical protrusion 15 on the opposite side of the first cylindrical protrusion 6, which enables guiding and rotation of the side followers 9, 10 with respect to the outer casing 1 present on both sides. .

Since the platen 7 has a thickness smaller than the thickness of the central hole 4 of the center follower 2, as described above, spaces are formed on both sides of the platen 7, and the side followers 9 in these spaces. The first cylindrical protrusion 6 of 10 is introduced to ensure rotation of the side followers 9, 10 with respect to the center follower 2.

The platen 7 comprises a circumferential tab 46 located in the two circumferential recesses 47 of the central hole 4 of the central follower 2, by means of this configuration the central hole of the central follower 2. 4) its position within is secured.

Locks that are the subject of the present invention may comprise a handling selector piece 16 and, depending on whether the handling selector piece 16 is inserted into the side follower 9 or into another side follower 10, The side of the lock, on which the piece 16 is introduced, always locks the latch 3 of the lock without the need to introduce, for example, a code, a key or the like to operate a motor 38 coupled to the system to exit the hotel room. It can be made to be the side of the lock which is the object of this invention operating as a handle to operate.

In order to fasten the handling selector piece 16 to one of the side followers 9, 10, the handling selector piece 16 is inserted into the through hole 14 of one of the side followers 9, 10, and also the center follower. In the center hole 4 of (2) it comprises two appendages 17 which are introduced into the curved hole 8 formed by the platen 7, so that the rotation of the handle shaft 19 with respect to the center follower 2. The pushing of the appendage 17 moves the center follower 2 and, together with this, the latch 3 of the lock which is the subject of the invention. Moreover, the handling selector piece 16 comprises a locking stop 18 located in the channel 20 of the central rectangular hole 13 of one of the side followers 9, 10.

The functional characteristic of the fastening stop 18 is to ensure a state in which the attachment 17 is inserted into the curved hole (8). When the shaft of the handle 19 rotates, the center follower 2 is rotated by the tension of the appendage 17.

This functional property is achieved because the shaft of the handle 19 is fixed to the fastening stop 18 to ensure the position of the appendage 17.

Thus, depending on the position where the handling selector piece 16 is installed, the operation of the lock can be performed on one side (right) or on the other side (left).

In locks which are the subject of the invention, this is possible without the handling selector piece 16, so that both sides of the lock cannot move the latch 3 of the lock without first operating the motor, and in this way both sides of the lock It is not possible to provide limited openings in this lock.

The lock, which is the subject of the invention, also comprises a pin 21, which is driven by two flanges 22 of the pin 21 introduced into the side housing 5 of the center follower 2. (2) is guided into. The pin 21 comprises a web 23 connecting the flanges 22 in addition to the two flanges 22.

The lock of the present invention comprises two points 24, one point 24 inside each side housing 5 of the central follower 2, which are adjacent to the flange 22 of the pin 21. To be located. The points 24 are introduced into the springs 25 so that the springs 25 abut the edges of the housings 5, and each side housing 5 loaded on the edges 48 of the side housings 5. It is located inside of.

The end of the flange 22 of the pin 21 has a recess complementary to the protrusion 26 at the end of the point 24 so as to keep the point 24 fastened to the flange 22 of the pin 21. 45).

Further, the lock of the present invention has an articulated end 28 so that the hook-shaped end 29 is connected to the pin 21, specifically the web 23 of the pin 21, and the other end is hooked. A cam 27 having a shaped end 29. By this configuration, the cam 27 can rotate around the articulated end 28 and move the pin 21 by this rotational movement.

The cam 27 includes a shaft 30 and a protrusion 31, a torsion spring 32 is inserted into the shaft 30, and the spring is formed to contact the protrusion 31 of the cam 27. And two ends of the other end formed to contact the protrusion 33 of the lever 34 described later.

The point 24 is fastened to the pin 21, the recess 45 of the flange 22 of the pin 21 is fastened to the protrusion 26 of the point 24, and the web of the pin 21 is fastened. By fastening the hook-shaped end 29 of the cam 27 to the 23, the entire assembly is tensioned under the influence of the torsion spring 32, so that the point 24 for operating the lock of the present invention is Unwanted operation is extremely difficult when point 24, pin 21 and cam 27 take into account floating connections.

The lever 34 of the lock that is the subject of the present invention includes a toothed end 35 and another articulated end 36 such that the lever 34 has the ability to rotate around the articulated end 36.

The serrated end 35 of the lever 34 is a first worm drive 37 sequentially connected to the motor 38 such that the motor 38 is operated in accordance with an electronic device that handles the access rights of the locks of the present invention. Interlock with.

As mentioned above, a lock that is the subject of the present invention may allow selection of the side of the lock that acts as a handle that always opens the door and the side of the door that requires approval to operate a component capable of opening the door.

The operation of the lock, which is the subject of the invention at the side requiring approval to operate the component that causes the door to open, is as follows:

The motor 38 is activated as soon as a key, code or the like is introduced,

The motor 38 acts on the toothed end 35 of the lever 34 by a first worm drive 37 such that the lever 34 rotates around the articulated end 36,

The rotational movement of the lever 34 causes the projection 33 of the lever 34 to come into contact with the torsion spring 32 at one end,

The end of the torsion spring 32 on the opposite side of the contact with the projection 33 of the lever 34 contacts the projection 31 of the cam 27, by means of which the cam 27. The torsion spring 32 rotates about the shaft 30 until it rotates around the articulated end 28 of the cam 27,

In the rotation of the cam 27, the point 24, in which the flange 22 of the pin 21 emerges from the interior of the sping 25, has its respective point 24 circumferentially around the side followers 9, 10. The end 29 of the cam 27 coupled to the pin 21 pushes the pin 21 towards the inside of the center follower 2 so as to push until it is introduced into the opening 11.

When the component of the lock is in the position described above (engaged position), the shaft rotation of the handle 19 moves the side follower 9 by pulling the central follower 2 by pushing from the point 3. And the latch 3 of the lock is moved.

In order to return the side followers 9 and 10 to their initial positions, the locks of the present invention are sequentially on the side springs 40 which are loaded onto the support pieces 41 which are fastened to the outer casing 1 of the locks. If the force exerted on the side followers 9, 10 is stopped as the shaft of the handle 19 is released, including the spring guide 39 being loaded, the spring guide 39 is moved to the side followers 9, 10. Which are pushed and moved by the circumferential protrusion 12 of the shaft 19 of the handle, which rotates and the lateral spring 40 moves with the spring guide 39 and the above-described side followers 9, 10. ) To the initial position.

In addition, in the case of the lock which is the object of the present invention, if there is no movement of the point 24 (since access is not allowed), and the point 24 is held outside the circumferential opening 11 of the side followers 9 and 10, The shaft of the outer handle 19 can rotate one of the side followers 9, 10, but the side followers 9, 10 do not rotate the center follower 2, so that the latch 3 of the lock No movement takes place.

Likewise, the locks of the present invention have a configuration that allows them to continue to operate correctly in abnormal operating situations, for example when the handle is rotated before the motor 38 is operated to move the remaining components of the lock. . In that position, the circumferential opening 11 of the side followers 9, 10 deviates from the point 24, so that the point 24 cannot access the circumferential opening 11 to allow rotation of the central follower 2. As a result, the latch 3 moves.

In this situation, the motor 38 acts on the lever 34 and the lever 34 acts on the torsion spring 32 which rotates about itself, resulting in the projection 31 of the cam 27. Considering that the point 24 is in contact with the periphery of the side followers 9, 10 and the pin cannot move when in contact with the spring, the spring 32 is locked by the cam 27 because the cam 27 is locked. You cannot move it. In this situation, considering that one end is locked by the protrusion 31 of the cam 27 and the other end is pressed by the protrusion 33 of the lever 34 that is storing energy from the motor 38, Torsion springs are tensioned. When the side followers 9, 10 align the circumferential opening 11 with the side housing 5, the cam 27 is no longer present because there is no longer a stop which inhibits the movement of the point 24 and the pin 21. Unlocked, the spring 32 is released from the load applied to it, and when the cam 27 is moved, the pin 21 moves in sequence and the point 24 moves. If closure occurs so that the point is held by the circumferential opening 11 of the side follower 9 or 10, the same process takes place in the opposite direction.

The motor 38 is connected to the drive shaft 43 by an output shaft 42 having a second worm drive 44 so that the drive shaft 43, which includes the first worm drive 37 at the other end, is provided with the first shaft. One worm drive 37 is connected to the toothed end 35 of the lever 34 of the lock.

Locks that are the subject of the present invention provide security features for the construction of the components of the lock itself and for the external manipulation attempts provided by the way in which they are connected to each other. For example, the connection between the flange 22 of the pin 21 and the point 24 by the recess 45 of the flange 22 complementary to the protrusion 26 at the end of the point 24 is point 24. ) And the pin 21 are prevented from being lost. It also provides security for the connection between the cam 27 and the pin 21, and the hook-shaped end 29 of the cam 27 hooks the web 23 of the pin 21, so that the cam 27 If not activated, the pin 21 is prevented from moving.
