Description

Improvements introduced in the Invention Patent nº P-200200790 / X, by: "Doorknob system folding-sliding, modular, with self-locking magnetic and multifunctional operability ".

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to improvements introduced in the Patent of Invention nº P-200200790 / X, by: latch system folding-sliding, modular, with self-locking magnetic and multifunctional operability, with which they are achieved remarkable advantages over the devices that exist in the currently and that are intended for the same purpose.

It is applicable to all types of locks for access control, from a simple door retainer to mechanical, electrical, and / or panic locks.

By the present invention, it is modified and perfect the doorknob system Folding-sliding of the Invention Patent principal and the first Certificate of Addition to it with number of application P-200301999, improving, modifying and providing mechanisms that confer new benefits and greater reliability, based on the principle of continuous improvement, achieving the opening of the latch by release, not by traction, with greater use of magnetic principles and the reduction of efforts and minimum consumption.

Some changes in geometry are contemplated, in some  cases, which provide smoother landslides, being used as guides the racks themselves or walls of the box or housing in the that are housed, making it possible even the redistribution of complementary elements in different planes.

Another improvement that is introduced in the latch system that concerns us, is the realization of a internal crenellated in the doorknob, which offers a particular system of interlocking interlocking to the attempts of traction by unraveling

Another object of the invention is to offer a Elemental and reliable panic electromagnetic lock, by the simple application of the core and mobile armor contemplated in the Main patent, associating them with a lever (parrot beak).

The development of a self-locking elementary inscribed in a slip of double angular and sliding abatement, through some connecting rods, the concept of opening in emergency exit mechanisms, basically having the same philosophy as the main patent and First Certificate of Addition, not forgetting, in this Patent of Invention that concerns us, the electromagnetic elements under planes inclined and the use of permanent magnets as alternative to conventional springs.

Background of the invention

The doorknob or slip is the emerging element most common lock in locksmith, and is defined as: lever cut in chamfer or bevel protruding from the front. Under the action of a spring is inserted when closing and automatically fits into the strike, thus ensuring constant immobilization.

The opening originates when the latch is retracted or slip by a knob, a handle, a handle, or a key.

Self-locking is a complementary mechanism to avoid retraction by frontal push of the latch; being able be mechanical, with levers and springs not exempt from friction and / or therefore wear. It is emerging and parallel to doorknob, or, integrated in it, case of doorknobs tubular, which prevent manipulation by pushing its inclined plane from the outside, this being the classic opening system of doors with cards in locks that are not locked.

In the electric locks its displacement either directly (electromagnet or motor) or through of the so-called load axis, which is a second slip of greater tensile stress that the handle and usually carry the self-locking associated with a series of levers to multiply the power electric

Both in the locks they usually carry pop-up self-locking, or through the load axis in the electric locks, its mechanical performance is complex with levers and springs, and not free of friction, it is very critical because depending on the light between the front plate of the lock and the lock, decreasing its effectiveness in the greater clearance between door and frame.

In the main Invention Patent No. P-200200790, a knob of the defined type was disclosed, located inside a housing and where four fundamental elements intervene for its functionality: the latch itself, the skate, a retaining lever and a rocker These four elements complemented by the operative form of retention that is selected from those that usually exist, or, specifically, for certain applications, provide new features in the field of locks.
jería:

The housing or lock case presents in its base parallel guides in order to improve alignment and sliding of the skate to which the rocker is linked, being the box closed by a lid and both attached to a front that serves of guide to the emergent elements: doorknobs and rocker.

The rocker is the element through which it get self-locking to prevent latch retraction once it is housed in the cashier.

The doorknob is hollowed out, having a prismatic base configuration in the form of a circular sector and It has a housing in its lower part and transversely for crimp with the skate, turning as a hinge through a axis, being also assisted by a recovery spring. Owns some tangential bezels on its sectorial side walls, the which do not cut the vertices of the upper part, thus forming stop means that limit the emergence of latch. Laterally it has some housings, one for each face, in one of which a retention lever will act which is oscillating to fulfill its function. The existence of accommodation on both sides it is to use the one that suits depending on the construction of the lock, when installing said lever retainer

The sliding skate carries the corresponding parallel grooves for proper sliding at the base of the housing, and in its upper part it has a recess to house the knockdown turning on it. On its back includes a projection with a through hole of the guide shaft on the which is mounted on the compression spring that holds the skate and by both to the handle in the emergency position with respect to the frontal, in the resting condition.

The retaining lever is an element that oscillates around an end axis perpendicular to the base of the housing and which is fixed to the skate, so that in a resting position is leaning against an emerging stop of the skate to adopt a longitudinal position to the direction of movement and not hinder the movement of the latch while in another angular position, the free end of this retaining lever interferes with the movement of the latch, preventing its retraction and therefore fulfilling its retention mission.

The two angular limit positions of the Retaining lever are achieved by the action of a magnetic field existing between a magnet that has the retention lever attached, and another that is inserted in the self-locking rocker.

This self-locking rocker rotates on an axis horizontal of the housing, being assisted by a spring Recovery. The magnet is located at the top and by both at a certain radial distance, being mounted with it polarity than the magnet of the retaining lever.

In the open door position, the latch and The rocker arm emerges from the front of the door. When you proceed to closing it, the strike first attacks the latch and immediately after the rocker. The strike only carries housing for the doorknob and therefore in the door position closed, the rocker is turned towards the inside of the lock, with its magnet facing the retaining lever causing a repulsion field, causing the retaining lever fit into the housing provided in the doorknob to produce the self-locking of it.

Well, based on these characteristics advantageous presented by the main Invention Patent, as opposed to the prior state of the art, the present invention that submits as the second Certificate of Addition to said Patent of Main invention, provides some improvements in several of its structural elements that improve the mechanism functionality.

Description of the invention

In general, the improvements introduced in Invention Patent No. P-200200790 / X, for: folding-sliding latch system, modular, with magnetic self-locking and multifunctional operability, object of the present invention, determine a range of locks of very broad spectrum, of the following characteristics:

A doorknob tilt-and-slide that presents the particularity, with respect to the patents cited in the background of the invention, that the two basic elements: latch and skate, have their axes guided laterally on racks or side walls of the lock housing while previously they were guided at the base and on the front.

The magnetic self-locking of the patent is improved of Invention and first Certificate of Addition, replacing it with One of mechanical type.

The side frames present for this purpose, two slots: one longitudinal for sliding the skate and the other in the form of a broken arc that allows both the slapping, at closing, as its retraction by varying the angle of rotation of the shaft upper when opening, after releasing the lock electromagnetic.

The skate, guided by the slide, is retained parallel and linear by means of a lever that releases, under tension, an electromagnet.

The handle with a structure similar to that described With reference to the main Invention Patent, it is retractable to the closure and is crenellated at the bottom. May present the folding-sliding variables to through connecting rods or inclined plane for better location of the blocking elements, which can also be double dejection when the slip in the form of a circular sector has two of its displaceable vertices by including two transverse axes in them which are guided in even arched grooves on the sides of the housing, as we will see later in relation to the figures.

In the case of application of the invention to a electromagnetic panic lock, is composed of:

The pivoting core on the frame, the mobile armor and a "parrot beak" type rocker that pivots around a transverse axis. The system is autoblocks when inserting an ejector or bridge into the existing slot for this purpose on said rocker lever, turning it and There is a recovery dock. Some microswitches they act on the magnetic core, switching and signaling the real open or closed state of the mechanism.

The doorknob system, in another application of the invention, maintaining the same philosophy of determining a retractable closure and opening by the convex plane of its shape geometric, can be guided in two arched grooves of the walls sides of the housing or frame, allowing double dejection and its linear transmission through connecting rods. The concept is maintained stress retention, instead of tensile stresses with the energy and functional advantages that this represents. The incorporation of connecting rods allows working on different planes complementary operating elements: retaining levers, coil, mobile armors, handle key opening, etc.

The crenellated mechanization of the latch and a suitable strike, they provide an interlocking system to the traction when complemented by a central locking.

The transmission of the opening movement, once the opening interlocks that are exerted on the retention lever are released, either by the remote action of a coil or by manual pressure on an articulated lever at the ends of two parallel anchored skates oscillatingly at the base of the housing, they determine an articulated parallelogram that presses and linearly displaces the driving lever of the retaining lever for its release.
tion.

The coil performs the remote opening of the bar  mechanics in controlled emergency exits, in the absence of voltage of the electromagnetic element between the armor and the core, replacing the fire doors function of placed electric door openers for that end.

Description of the preferred embodiment

Referring to the numbering adopted in the figures and especially in relation to figures 1 and 2, we can see how the doorknob system folding-sliding, modular, with self-locking magnetic and multifunctional operability, which includes improvements to The present invention allows the manufacture of a range of very wide spectrum locks as we had indicated previously. In a very simple embodiment as shown in the Figure 1, the doorknob (1) tilting-sliding, it is crossed by axes (2) and (3) whose protruding ends they play in the respective slots (4) and (5) practiced pair in the two side frames (6), or side plates on which in turn contact the sides of the prismatic latch (1), thus having an optimal guidance.

The magnetic self-locking of the Patent of Main invention, it is changed by a mechanical lock materialized by the actuation of the oscillating lever (7) that in its end includes an angled end retention tab also layered sliding skid (8). Action is released rocker lever retainer (7) by electromagnet (9).

A new arrangement is shown in figure 2 of these same functional elements of the doorknob, changing from place the locking elements (7) and (8), when providing connecting rods (10) couples. In this figure 2 is also shown with lines of strokes another operational position. In this case, the retaining lever (10) is connected in a staggered mobile armor (11) and allows to locate the electromagnet (9) in the opposite part.

With special reference to Figures 3 to 5, the tilting handle (1) is similar in configuration to that of the main Invention Patent, retractable at closing and has a crenellated in its lower part, referenced with the number (12) and formed between two recesses recessed (13) of the major faces thereof. This geometry corresponds to that presented by the strike (14) as clearly seen in Figure 4. In the crenellated recess (15) it is possible to introduce the wall (12) of the latch of the latch (1), passing from the position from emerging (Figure 3b) to blocking (Figure 3a). The reference (16) designates the front of the lock, in this example of embodiment of figure 3. It can present the folding-sliding variables through connecting rods or inclined plane, similar to that commented in relation to figures 1 and 2. It can also be double dejection: slip of figure 7 of which we will talk more
ahead.

The system always allows closing and opening unless the door incorporates a conventional closure centralized, as is the case of the example shown in the figure 5. Given the peculiarities of the crenellated and the geometry of the strike (14), this system prevents, with the support of the central closure (17), traction unlocking (levers) between door and framework. Reference (18) designates the door hinges. The crimping elements are materialized by the latches 1.

In figure 6 where an elementary is shown electromagnetic panic lock, it is composed of three basic elements: the core (19) pivoting on the front of the frame (16), the mobile frame (20), and the rocker lever (21) of the type called "parrot beak" that pivots on the axis (22). The ejector or bridge that is inserted into the opening (23) of The rocker lever (21) is referenced with the number (24). The system self-locks when the ejector (24) is inserted into the slot (23), for the attack on the inclined planes of said groove (23) for the reduction of efforts, as deduced when observing the different positions a), b) and c) of figure 6. The spring (25) provides the rearmament and retention support, as well as the microswitches that act on the magnetic core (19) (not shown) by switching and signaling the actual open state or Closed mechanism.

In relation to figure 7 which also includes three sequential operating positions a), b) and c), we see that the Doorknob of this lock, like that of the applications precedents, maintains the same philosophy as that of the Patent of Main invention: retractable closure and opening by plane convex. In this case the differential nuance is the realization in the frame (6), of the two arched grooves (26) and (27) for allow double dejection. The linear transmission is made at through the connecting rods (28).

Self-locking or oscillating part inside of latch 1, is referenced with the number (29) (in the Figures 1 and 2 this element (29) is also observed, the component that first contacts the locksmith referenced in this case with the number (30). Your recovery dock acts very simply as seen in the three sequences of this figure 7, on a retaining stop (31) that is find crimped to the connecting rods (28).

In this figure 7 the spring has not been represented for recovering the emergency position of the latch (1), being a double winding torsion spring, located between the retaining stop (31) and the latch (1) itself, in order to Do not overload the drawings.

For the opening movement, once it they have released the interlocks that are exerted on the lever (7) is obtained by remote action of the coil (9), or that exerted by the manual pressure on the lever (32) that joins oscillatingly free ends of the skates (33) that oscillate at fixed points of the base (34). Thus a parallelogram is formed articulated to move the driving lever (35) which is carrier of an inclined plane (36) at its active end, raising the rear axle (37) of the retaining lever (7 '). In this case said lever has been referenced with (7 '), being provided with a extension (38) with a bulge, which will be acted upon by the nut (39), thus opening. The recovery of the Retaining lever (7 ') is achieved by permanent magnet action (40).

The driving lever (35) indicates its operability, presence signal, when switching a microswitch duly installed and that has not been represented, sending a signal, remotely, when the panic bar incorporates the electromagnetic retention effected by the armor (41) and the magnetic core (42).

The mobile armor (41) is provided with a stepping to be retained by the lever (7 ').

The mobile armor (41) associates a spring of traction (43) recuperator of the primitive position, replacing the classic electromagnetic suction cups that are installed complementing the mechanical bars in the emergency exits controlled.

The mobile armor (41), in addition to the planes of retention on which the core (42) and the lever (7 ') act, It has a prismatic finish in its front part (44) that it serves as a containment of the retention levers (45), (as it is observed in figure 8, positions a) and b)) to release in its unlocking the fallebas (46), having these at their ends lock (upper-lower or lateral) ones latches similar to the center of the bar, or the one represented in Figures 1 and 2. The retaining levers (45) include in their two pivot ends (47) linked to the fallebas (46).
