Description

Automatic reversible forwarding for locks multipoint

Field of the Invention

In locks, by forwarding means that additional closing point to the one that resides in the central lock and which is opened from this central lock to open and / or close by means of fallebas.

This invention concerns a forwarding that at same time is automatic and reversible; automatic because for your closure the intervention of the central lock is not required, but which is produced simply by bringing the door to position closing on its frame; reversible, because the same mechanism It can be used for right or left doors without having to do any modification in it. Auto close function allows you to make the forwarding of the central lock independent, in front of an attempt to violate it that tries to force the retraction of  the central lock lever applying an external force frontal; this action will not affect the forwarding, since these can only be opened through the fallebas when they are driven by the legal opening maneuver (by handle or key) made in the mechanism of this central lock.

Prior art

To get the auto close function, in general, a mechanism that allows establishing a closing sequence in which the output of the closing lever does not possible until a trigger device is operated previously.

There are mechanisms in which this sequence operational is achieved through intermediate withholdings that keep the lever retracted until the door reaches its final closing position in the frame and this lever is facing the locksmith.

This type of mechanism is complex in its constitution, assembly, number of parts and functional relationship between the same; which, translates into risk of dysfunctions that, for avoid them and guarantee the necessary reliability, force a great precision in manufacturing and assembly that result in a very expensive product that will be applicable in level facilities medium-high This is a problem in what I know refers to the central lock and, of course, to a greater extent for a mechanism of lesser entity such as forwarding.

Everything said acquires even greater relevance if it is also intended that the mechanism be reversible and that this power is achieved with minimum or no modification of the mechanism.

Explanation of the invention and advantages

Faced with this state of affairs, this invention advocates a constitution of automatic and reversible forwarding that it consists of a sandwich structure that is constituted by a rotary lever that is shaped like a hook with a bevelled front "V", hereinafter hook, by a horizontal trigger Sliding head that has a "V" bevelled tilting head mounted on a vertical axis of rotation, hereinafter trigger tilting, for a first compression spring, for a second compression spring and by a tension spring, all of which are mounted and operate between two twin vertical plates that, with vertical sliding adjustment, they are attached to the walls sides of the forwarding box; the hook is formed by a head and foot, the head, behind its beveled forehead, is flat and thick so that its sides are flush with the exterior of the vertical plates while the foot is embraced with sliding adjustment between these vertical plates, and this hook rotates on a first axis that is in its foot and that, regarding your extended operating position or location in your door closing frame striker, this first axis is escorted by a pair of collateral front breasts and by a rear orified fin, while in relation to its position operating or resting mechanism ready for firing automatic closing when the door is carried to its frame, this hook has a horizontal shoulder and two protruding collaterals in "L" that have their concavity back; the trigger swingarm is likely to adopt tilted positions in which, with respect to the closing turn of the door on its frame, the front bevel of the tilting head is delayed with respect to the front bezel of the front of the hook, and, in its part bottom and rear, this rocker trigger incorporates a trigger vertical that is mounted on a second axis of rotation that is transverse to the body of the rocker trigger itself and that, Regarding the resting position of the hook, this vertical trigger is capable of adopting a forward operational position in the that its tip is applied on the horizontal shoulder of the hook; the first compression spring operates between the rear front of the rocker trigger and forwarding box; the second pier of compression is between the rear of the vertical trigger and the body of the rocker trigger itself; the traction spring is between a lower end that is hooked on the orified fin rear of the hook and an upper end that is hooked on the forwarding box in a convenient place higher than the first axis; the vertical plates operate between two upper positions and bottom stop on the forwarding box itself, they have union with a coupling failure with the central lock and present a deep front neckline in which the head plays and a window in the form of "4" which is constituted by a vertical branch sliding back adjusted with respect to the first axis of the hook, and by front horizontal and vertical branches in which, with convenient slack, play the front teats of the hook as well how these vertical plates form a vertical front Forward.

Another feature of the invention consists in that, with respect to the resting position in which the door is separated from its frame, the vertical plates are in position upper, the tension spring is tensioned, the trigger tilting is in its most emergent or maximum operating position relative relaxation of the first compression spring, the trigger vertical is in its forward or maximum operating position relative relaxation of the second compression spring, while its tip is resting on the horizontal shoulder of the hook, and the front studs of this hook are against the upper edge of the horizontal branches of the window.

Another peculiarity of the invention is that, in a position in which the door is in the frame but not reaching the end of the closing path, the rocker trigger is partially retracted against the first compression spring, the hook has its beveled front against the door frame for not have still reached its strike on it, the vertical plates  they remain in their upper position, the traction spring is more tensioned, the vertical trigger is not resting on the shoulder horizontal of the hook, the front lugs of this hook are against the upper edge of the horizontal window branches and the top edge of his head keeps a convenient separation from the upper edge of the front neckline of the plates.

Another peculiarity of the invention is that, in a position in which the door has reached the end of its closing path and the hook has already entered its locksmith's frame, the vertical plates are in their lower stop position against the forwarding box, the traction spring is relaxed, the rocker trigger is partially retracted against the first compression spring, the front hook studs are in a place along the front vertical branch of the window in "4" shape and the vertical wall of the protrusions in "L" of the head of the hook are adjacent and aligned horizontally regarding the front vertical fronts of the plates.

Another peculiarity of the invention is that, in the closed door position in its frame, when driving it failed in the opening maneuver, the vertical plates are displaced in the sense that the front lugs make a first travel in the front vertical branch of the windows to reach the horizontal branch of it, at which time, when be the tops of the plates, the lower edge of the horizontal branch can push without obstacles on the lugs front allowing the retraction of the hook to its complete exit of the strike in which the maneuver of separation of the door from its frame, while it is driven the rise of the plates to their upper position.

Another peculiarity of the invention is that, in the door separation maneuver with respect to its frame, the bevel front bezel of the head of the hook that is in the sense of maneuver, is delayed with respect to the tip bevel of the rocker trigger so that it comes out in first when it opens when the door is opened and secondly the hook. So when completing the separation of the door, the hook reaches its resting position in which the trigger tip vertical rests on the horizontal shoulder of the hook.

This constitution employs a small number of parts, quite simple configuration and that are related in a simple way that ensures reliable operation, while its manufacture and assembly involves a fairly small cost. These qualities will be very evident through the description of your operation and graphic representation of an execution preferred as set forth below.

To anticipate the essence of this operation we are going to start from an initial position where the door is separated from the frame on which it is to close; this position is the standby or armed mechanism for automatic firing; in her both the hook and the trigger show enough to  influence the frame when closing the door, so that the trigger is at the front end of its operational career and the oscillating trigger mounted on it retains the output of the hook by supporting its tip on its shoulder latest; in the closing maneuver of the door it is the hook that first it affects the frame and begins its retraction, then what makes the trigger to a point where the trigger tip swinging can no longer interfere with the shoulder when the hook can check its exit, which happens as soon as the hook Reach the position of your strike and can take advantage of the drive spring traction spring; while the hook slips on the frame in search of the locksmith his front breasts are in the horizontal branch of the window in the form of "4" retaining the vertical plates in their upper position; when the hook comes out these lugs are between the edges of the front vertical branch (which allows vertical plates to fall by gravity to their lower operating position) and the vertical front of the plates it is adjacent and in horizontal alignment with the projections in "L" from the hook. To open, the central lock is activated and the  produces the impulse of the fallebas in the sense of returning the vertical plates to their upper position, which determines that the horizontal branch of the windows in "4" push the lugs sides of the hook and cause the hook to exit the strike; then, when separating the door from the frame, it is first abandoned by the trigger and recovers its front operating position, in which its trigger is positioned so that its tip will interfere with the shoulder of the hook when it leaves (secondly) the frame, producing the retention of this hook in its loading position Ready for a new automatic shot.

In the closing position there are two locks facing an attempt to force the retraction of the hook by pushing from its tip; one, is that of the lugs that remain between the edges of the front vertical branch of the window at "4"; he another is the adjacent horizontal confrontation of the front of the vertical plates with respect to the projections in "L" of the head of the hook. Therefore, in this functional sequence there is no intermediate holds, as are known in other devices existing. The situation in different planes and different angles of the tilting head and the bevels of the hook, ensures that in the door closing maneuver the hook will always affect Operationally first on the frame. Tilt head of the trigger ensures that if it were in the wrong position presenting a bevel in front of the hook (according to the closing turn of the door), at the time of impacting on the frame would swing to the correct delayed position and the sequence would occur according to as explained above without interfering with it; one time closed the door, when opening the tilted position of the head is maintained during opening by a coining effect that is secured by the first compression spring drive.

Reversibility is achieved through "V" bevels of the hook and tilting head of the trigger, together with the aforementioned tilting capacity of is.

According to this constitution, figure 1 represents the resting position in which the door (10) is separated from its framework (11) and the mechanism is in a situation of loaded and ready for automatic firing; in such a situation the vertical plates (1) are in their upper position, the spring of traction (6) is tensioned, the rocker trigger (3) is on its most emergent operating position or maximum relative relaxation  of the first compression spring (4), the vertical trigger (3b) is in its front operating position or maximum relative relaxation of the second compression spring (5), while its tip is resting on the horizontal shoulder (2f) of the hook (2), and the front lugs (2d) of this hook (2) are against the edge upper of the horizontal branches (1d) of the window (1b).

According to the invention, with respect to the operating direction, the hook (2) is offset from to the tilting head (3a) of the tilting trigger (3) and, to close the door (10), the frame (11) hits the first of the "V" bevels of the hook (2) and then the tilting head (3rd).

Starting from this situation, when carrying the door (10) to the frame (11) as indicated by arrow (12) (figure 1), the hook (2) strikes it before the tilting head (3a) of the trigger (3) and a position is reached as illustrated in Figure 10, where the hook (2) is already more retracted than the trigger (3); here the tension spring (6) is more tensioned, the trigger (3b) has its tip separated from the shoulder (2f) and the stubs (2d) are along the horizontal branch (1d) of the Window (1b) of the twin vertical plates (1). Observing the enlarged section that is included in figure 1 is comprised of immediately the tilting function of the head (3a) which, together with the double bevel shape thereof and the hook (2), determine the reversibility of forwarding without having to intervene in it so some, but by reason of its own design.

Another peculiarity of the invention is that, in a position in which (figure 11) the door (10) is in the frame (11) but without reaching the end of the closing path, the rocker trigger (3) is fully retracted against the first compression spring (4), the hook (2) has its bevelled front against the frame (11) of the door (10) for not having yet reached its strike (11 a) in it, the vertical plates (1) remain in its upper position, the traction spring (6) is more tensioned, the vertical trigger (3b) is not supported on the horizontal shoulder (2f) of the hook (2), the front lugs (2d) of this hook (2) are against the upper edge of the branches horizontal (1d) of the window (1b) and the upper edge of its head (2a) maintains a convenient separation from the edge upper of the front neckline (1a) of the plates (1); is separation will ensure that the hook outlet (2) is not going to be hindered by vertical plates (1).

According to the invention, it is also true that, in a position (figure 12) in which the door (10) has reached the end of its closing path and the hook (2) has already entered into your strike (11a) of the frame (11), the vertical plates (1) are in their lower stop position against the forwarding box (7), the traction spring (6) is relaxed, the trigger swingarm (3) is fully retracted against the first spring of compression (4), the front lugs (2d) of the hook (2) are in a place along the front vertical branch (1e) of the window (1b) in the form of "4" and the vertical wall of the projections in "L" (2g) of the head (2a) of the hook (2) are adjacent and aligned horizontally with respect to vertical fronts front (1f) of the plates (1). As you can see, in this position, when trying to force the retraction of the hook (2) by acting on it, the front breasts (2d) of this one stop against the rear edge of the front vertical branch (1e) becoming insurance for this purpose; If this insurance fails, there is the insurance offered by the front vertical front of the vertical plates (1f) in conjunction with the vertical wall of the outgoing in "L" (2g).

In relation to the opening maneuver by the central lock (9), according to the invention is fulfilled which, in the position (figure 13) of door (10) closed in its frame (11), by driving the failure in the opening maneuver, the plates  vertical (1) are displaced in the sense that the lugs front (2d) make a first (empty) route in the branch front vertical (1e) of the windows (1b) until reaching the horizontal branch (1d) of the same, at which time the projections in "L" (2g) of the head (2a) of the hook (2) and the fronts front verticals (1f) of the plates (1) are no longer facing each other, removing blockages and allowing the edge bottom of the horizontal branch (1d) push on the lugs front (2d) in the direction of the hook retraction rotation (2) until its complete exit from the lock (11 a) in which it is possible the door separation maneuver (10) with respect to its frame (11), while the ascent of the plates (1) is driven until Your upper position. In this regard, and once the hook (2) has been fully retracted to reach in reverse maneuver the position of figure 11, according to the invention it is fulfilled that, in the door separation maneuver (10) with respect to its frame (11), the bevel of the bevelled front of the head (2a) of the hook (2) that is in the sense of the maneuver, is delayed with respect to the bevel tip of the rocker trigger (3) and, upon completion of the door separation (10), the hook (2) reaches its position of rest where the tip of the vertical trigger (3b) is supported on the horizontal shoulder (2f) of the hook (2); which translates in which the trigger (3) is the first to leave the frame (11) to recover a position like the one in figure 10 and stay at waiting for the hook to exit (2) to retain it as indicated in Figure 1

Also the oscillating vertical trigger (3b) it has an independent, tilting or linear movement with respect to the  rocker trigger (3), so that in the case of jumping manual forwards, without closing the door, when removed by handle or by the key, the hook (2) on its way back can remove the vertical trigger (3b), so that your shoulder is left horizontal (2f) behind the vertical trigger (3b), when returning the vertical trigger (3b) to its initial position and thus, the hook (2) retained and in its firing position.
