Description

Automatic overlay lock and panic

Field of the Invention

This invention concerns a lock of superimpose high-end that is equipped with a mechanism that provides a double function: on the one hand, a trigger function automatic, that is to say, that its closure is produced by the mere fact of bring the door to its closed position in the frame; for another side, a panic opening function, that is, being the closed lock in its frame, the door can be opened from inside by simply operating the inner handle, by means of a maneuver sequential that in the first instance releases the condemnation of the retracted position of the latch (s) or closing lever (s) enabling the opening of the mechanism with the simple continuation of the handle operation inside.

Prior art

A high-end lock mechanism is itself something complex that, like watchmaking, consists of numerous pieces that have to make coordinated movements to achieve the opening and closing by reliable precise operation and soft.

The complexity in the design of these locks increases progressively when, in addition to being able to be open by an internal handle (handle or knob) and by means of a key, It is intended that, as is the case at hand, incorporate the same time the above shooting or closing functions Automatic and panic opening.

A permanent objective in this field, which with more or less fortune has guided the various known solutions to date, it consists of achieving a functioning design what as precise, smooth and reliable as possible, using simple parts in the least possible number, which will also result in getting a comparatively economic and competitive cost.

Explanation of the invention and advantages

The configuration of the pieces is reflected by figures 1 and 12 to 20.

The operation of the lock is illustrated using figures 2 to 11. To facilitate understanding, will explain below separately the operations for the automatic closing (figures 2 to 6) and for panic opening (Figures 7 to 11).

For automatic closing we start from the position of figure 2, where the lock is open and the door is separated from its frame, with the latch-trigger (8) in its extended position; this figure shows the possibility that the lock incorporate upper (14) and lower (15) outputs to respective secondary closing points; the situation of significant pieces is that the doorknob-trigger (8) is driven by the first spring (10) and, by the first axis (8c), on the latch-trigger (8) is articulated the first elevator (8a) which, with its second stud (8b), acts inside the window rectangular-horizontal (3rd) of the vertical blocker (3), being initially next to its upper left vertex in figure 2; the first leg (8d) is just ahead of the second leg (9a) of the trigger (9) which, in turn, is loaded elastically with the second spring (11). By bringing the door to frame occurs (figure 3) retraction of the doorknob-trigger and the first leg (8d) drives on the second leg (9a) and forces the trigger (9) to make a elastic jump up and down against the second spring (11), so that the first leg (8d) happens to be behind the second leg (9a). At the moment the door reaches its position closing in the frame (figure 4), the latch-trigger (8) can now exit to your extended position, with which the second leg (9a) forces the first lift (8a) turn on the first axis (8c) to its position descended in which the second stud (8b) runs through the groove arched (8f) and pushes on the upper edge of the window rectangular-horizontal (3rd) of the vertical blocker (3) and produces the rise of it so that its upper flange (3b) release the hitch on the teeth (6b) of the lever plate (6), which is projected (figure 5) to its position of levers (6a) extended by the drive of the first arm (5) that is loaded with the third spring (12) and it has upper bumper (5a) in the first vertical groove (6c) of the lever plate (6). Before completing the departure of the levers (6a) (figure 5) the prominence (6d) pushes on the fourth pin (9b) of the trigger (9), which rotates on its second axis (9c) to perform a new elastic jump and enable the first elevator (8a) recover its ascended position, in which the third stud (8e) descends (figure 6) in its arched groove (8f) and the vertical blocker (3), by the gravitational action and the elastic drive of the third spring (13), returns to its position descended, in which the upper flange (3b) engages in the rear tooth of the teeth (6b) while the lower flange (3g) does it on the tooth (6f) of the horizontal edge (6e), leaving thus the lock closed and retained.

To explain the panic opening we start from the position of figure 7, where the situation is the same as the Figure 6, that is, the door in its frame and the closed lock and held. When starting the opening maneuver with the handle inside, by one or another interposed means is applied a backward traction within the second vertical groove (1b) of the second arm (1), as indicated by the arrow marked in the figure 7. Then, as Figure 8 shows, this second arm (1) rotates on the fourth axis (1a) so that its curved convex profile (1j) ascends to the seventh stud (2a) of the second elevator (2), the which, in turn, ascends and pushes up the first stud (3d) which belongs to the slide (3c), with which the vertical blocker (3) and eyelash disengagement occurs upper (3b) and lower (3g) enabling the lever plate (6) is released from its retention (Figure 8) and can be retracted by continuing with the action on the inner handle; at the same time it happens that in the window rectangular-vertical (1h) is located the eighth bumper (4a) of the first rocker (4) which, by turning on the sixth axis (4b), places its first rear front (4c) against the lower bumper (5b) of the first arm (5). By continuing this action (figure 9), the lever plate (6) is retracted and the spring (3e) drives the slide (3c) to recover its natural position reached rear, which the first busty (3d) leaves the support on the second elevator (2) and the vertical blocker (3) descends to its lower position, which is also enabled because the seventh busty (2a) can descend down the slope front of the curved convex profile (1j); then, the tabs (3b) and (3g) become the retention position of Figure 2.

Finally, figure 10 illustrates a security incorporated by this advocated mechanism; it's about guaranteeing that, even if the lock is already open, the door cannot be separated from the frame before there is certainty that the lever plate (6) is held in position withdrawn For this, it happens that when the lever plate (6) is already retracted and retained, the latch-trigger is still extended and the Inner handle has not yet reached the end of its opening turn; then, the front front (1k) is against the ninth busty (7a) of the second rocker (7) (figure 10) and, when making the final turn, the second arm (1) already reaches (figure 11) its forward position and  produces a rotation of the second rocker (7) on its seventh axis (7b) causing the second rear front (7c) to drive on the third bumper (8e) retraction of the latch-trigger (8); now the door can be separated from its frame and once done, when the action on the inner handle ceases, the latch-trigger will come out again under the first spring drive (10).
