Description

Multiple lock with device anti-retraction of the latch.

Field of the Invention

This invention concerns a lock multiple with anti-retraction device latch, of the locks equipped with resends that produce closing points additional to that of a main lever of the own box of this lock, of the locks that have a latch and a main lever, of the locks that incorporate an anti-panic mechanism that produces the output of said lever main by a certain turn of a handle of the lock nut made in the opposite direction to that of the opening maneuver, and of the locks whose said latch is installed on a rod that is retractable by simultaneous action of some nuts and nut supplement fixed in the sides of this nut.

In particular, the invention aims at a safety device that prevents the handle can be retracted by pressing on it when the door latch is entrusted exclusively to this doorknob, that is, without being said main closing lever. Also, this invention It aims at some peculiarities of the mechanisms of said forwarding, intended to enhance its performance and reinforcement of its structure.

Prior art

Due to routine or comfort performances of the user it is very frequent that when closing the door on its frame the main lever is not thrown, so that the closing of this Door is exclusively entrusted to the latch or slip.

This type of closure is easily violent. by thieves by the simple procedure of pushing it inward with the edge of a credit card, a plaque radiographic or similar, introduced by the slot between the singing of the door and its frame. For this system it is quite current that a thief accesses the house, even being his dwellers within it.

A kind of lock that doesn't have this problem is the one that has both closing mechanisms automatic and panic; that is, locks that, when carried the door on the frame, automatically produce the output of all the closing elements (latch and lever or levers), and that, however, can be opened with the simple drive of an inner handle (without the need for a key), to prevent they become an insurmountable barrier in cases of flight precipitates motivated by panic situations. The inconvenient of this kind of lock is its high price and that require a high-precision door-frame installation, so that its installation is minority.

In this regard, some mechanism is required simple that condemns the retraction of the handle when the door be on the frame and can be incorporated into the locks more usually installed than those with doorknob, lever principal and forwarding that produce additional closing points to the main or central lock; and this mechanism must act automatically when carrying the door on the frame (for not be subject to the user's forgetfulness), as well as having the panic property so that this conviction anti-retraction of the latch be removed automatically when performing the normal opening maneuver of the lock with a medium always available as is the handle itself inside of it.

In another order of things, the forwarding of these multiple locks often have a limitation constructive in terms of the output capacity of its levers in horizontal direction, since this movement comes from a vertical drive produced by the lock mechanism and that it is converted directly into horizontal action by means of a simple inclined plane device; as the ability to vertical displacement generated by the lock mechanism is constructively limited to a reduced extent and is of difficult and expensive expansion for reasons of space and complexity in the same and design of this mechanism, this results in direct a similar limitation in the effective departure route of the levers of these resends.

Another problem with forwarding is that your restraint front is entrusted to a simple tab tied to the sheet of front of the lock on each side (upper and lower) of the output of their respective lever; which is weak against actions to force the closing by leverage and that produce deformation of the eyelashes backwards to the detriment of the lever output, which is reduced to the same extent in which they have yielded other tabs.

Explanation of the invention and advantages

In the face of this state of affairs this invention concerns a lock of the type expressed in the field previously defined for it; being a main object of it a peculiar constitution that includes a sentence, a insurance, an actuator of said insurance, an actuator of said conviction and one or more of said forwarding; where, in relation to the vertical operating position of the lock, said conviction presents a substantially vertical front front, an upper ramp rearwardly rising, an upper edge noticeably horizontal, an oblique window of variable amplitude and an axis butt around which this sentence is likely to swing between an inferior, non-condemning position, and a top position, condemnation, and is mounted against a first spring whose elastic load is relatively greater in said non-condemnation position; said insurance has a upper oblique side facing forward, a frontal appendix which is below said oblique side, a projection transversal that crosses through said oblique window of the sentence and a lower axis around which this safe is able to rotate between a front position, wherein said front appendix appears in front of said lock box in parallel to said latch, and a rear position, in which said front appendix it is retracted in said lock box, whose lock is mounted against a second spring whose elastic load is relatively greater in said retracted position; said insurance actuator is jointly attached to said rod and has a rear front vertical that faces horizontally with said front conviction forward; said conviction actuator has a horizontally guided sliding mount and features a fin that It is applied on the back of the arm that has such a sheet and nut supplement to boost the retraction of the handle, as well as it has a transverse stud that, in relation to said lower (non-conviction) and higher positions (conviction) of said conviction, is likely to be located just above said upper edge of this sentence or horizontally applied on said upper ramp thereof, respectively.

In this regard, another peculiarity of the invention is that, in its said forward position hovering by in front of the lock box, said front appendix of the lock lacks a corresponding strike in the closing frame of the lock, is included within the vertical projection of said latch and protrudes to a conveniently greater extent that the distance between the front of the lock and said frame of closing, while its transverse projection is located no clearance at the highest and narrowest front end of said oblique window of a said sentence located in its bliss inferior position (non-condemnation) of relative major elastic load of said first spring while said side oblique of this insurance is distanced from said rear front of the actuator to a somewhat greater extent than the horizontal distance existing between said front front of the sentence and the back of said doorknob. Also, in its lower position (non-condemnation) and in relation to said busty transverse of the actuator, said condemnation is left with its said edge upper just below the level of said transverse stud and at a horizontal distance from it less than that between said front of the actuator side oblique side of the insurance.

To explain how this works device we start from the open lock position (lever main retracted) and door separated from the frame, whereby the latch and the front appendix of the insurance hover over the front of the lock and the sentence occupies its inferior position (non-conviction) bound by the coupling of transverse projection of the latch on the front and top end of the oblique window of it. When taking the door to the frame an automatic two-stage maneuver takes place; in the first time, before the handle reaches its lock in the frame, both the handle and said front appendix are retracted in the same movement, by the actuator thrust mounted on the rod when hitting the insurance, in a maneuver in which the doorknob can perform a certain initial recoil without anything otherwise change, so that when said transient projection he is taken backwards allowing the sentence to rock his upper position (condemnation) driven by its first spring, this conviction is found that he can't do it because he bumps into him own doorknob; in the second half, the doorknob reaches its strike and penetrates into it, while the front appendix of the sure you have to stay withdrawn enabling the conviction ascend to his superior position of condemnation, in which his forehead front is next to the back of the latch preventing its retraction, while the upper ramp of this sentence is applied to the back of the transverse stud of the actuator sentence.

Once this position has been reached, the opening will be Produces with panic function. In fact, just activate the interior handle that rotates the nut in the normal maneuver of opening; then, while the arms of the nut plate and the nut supplement drives the retraction of the doorknob also  they drag the condemnation actuator which, with its transverse stud, pushes on the upper ramp of the sentence and forces it to occupy its inferior position (non-condemnation) before the doorknob reach the place that used to occupy the front of This sentence. That is, performing the normal opening maneuver With the inner handle, automatic removal of an insurance that prevented the forced retraction of the latch by violating the closure, and whose insurance had also been established automatically by simply bringing the door to its closed position on the frame.

Another object of the invention is related to some  devices for forwarding that are capable of multiplying the vertical displacement produced by the lock for the benefit of a greater measure of output of the corresponding levers. From according to an embodiment in this regard, the invention comprises a said forwarding provided with a secondary lever of linear closure, a first drag piece and a rocker; where, bliss secondary lever is rigidly mounted on a first plate which has a first vertical slide as well as a first inclined slide which, in relation to the output maneuver of said linear lever has vertical extensions initial and final; said first drag piece incorporates a third pivot located slidably in said first slide inclined from the first sheet and has a guided sliding assembly vertically between two extreme positions, initial and final, in the  that said third pivot is located, respectively, in said initial and final extensions; and said seesaw has a operational configuration in square formed by a major arm whose end has a joint confined in said first slide vertical of the first sheet and by a smaller arm than at its end it is provided with a longitudinal opening in which it is susceptible of sliding a first pivot installed in said first piece of drag, and whose rocker arm is likely to rotate around a second pivot that is fixed to a corresponding box that it houses the mechanism of these forwardings, determining two positions extreme, initial or rear and final or front, such that, in said rear position, said major and minor arms are, respectively, vertical and horizontal, said linear lever is inside or outside the forwarding box and said first piece of Drag is in its initial or final positions. In this execution The rocker is responsible for the aforementioned multiplier effect, because its major arm produces a swing when horizontal much larger than what would correspond to an effect of inclined plane for the same amount of vertical displacement produced by the lock.

Another embodiment, in this regard, of this invention it is the one that includes a forwarding said endowed with a hooked lever and a second drag piece; where, said hooked lever it is rotatably mounted on a second sheet provided with three sliders, which are, a second vertical slide, a second inclined slide which, in relation to the output maneuver of This hooked lever is equipped with extreme extensions initial and final verticals, and a horizontal slide, and whose hooked lever has a fourth and fifth pivots that are conveniently arranged at a different level, said fourth pivot is slidly confined in said second vertical slide and said fifth pivot is slidably located in said horizontal slide and around it this hooked lever is liable to rotate between initial or retracted positions and final or extended where this fifth pivot is located in respective relative positions front and rear along said horizontal slide; and said second drag piece incorporates a sixth pivot located slidably in said second inclined slide of the second sheet and has a mount vertically guided slide between two extreme positions, initial and final, in which said sixth pivot is located, respectively, in said initial and final extensions.

In any of these executions, all right with the invention, said resends are mounted in a box that It is constituted by two equal pieces, or half-pieces, which are coupled to each other in mutually inverted position and each one of them has two front tabs, first and second, one on each side of said linear or hooked levers and arranged in a different plane, so that said first front flange is  tucked into said second front flange, and whose front and second front tabs are aligned with each other two holes embedded and having reciprocating threads of the  of a clamping screw, the first front flange having a tip embedded in a groove that belongs to the opposite half and which is located next to the second front tab of this semi-opposite. This constructive mode provides a considerable structural reinforcement of the forwarding box, since at each mooring point two tabs now coincide, in instead of one, and they are also stiffened by themselves mooring screw that links them to each other and by penetration from the tip of the first tab in the half-slot opposite.

Another feature of the invention consists in that said first and second drag parts have a "C" configuration with lower upper limbs straight and horizontal at their ends have two hooks mutually faced and that are susceptible to coupling detachable with respect to upper or lower braces that transmit the vertical actuation of the lock towards said forwarding. This configuration enables a large removable linkage. reliability to said upper and lower braces.

Exhibition of a preferred embodiment

Regarding the drawings and references listed above, a mode of preferred embodiment of the invention, which concerns a multiple lock of the endowed (figure 1) of forwarding (9) that produce additional closing points than a main lever (2) of the box itself (3) of this lock, of the locks that they have a latch (1) and a said main lever (2), of the locks that incorporate a panic mechanism that produces the output of said main lever (2) by a certain rotation of a nut-operated actuator handle (4) of the lock made in the opposite direction to the opening maneuver, and of the locks whose said latch (1) is installed on a rod (1a) which is retractable by the simultaneous action of some plates of nut (4a) and nut supplement (4b) fixed on the sides of said nut (4).

According to the invention an essential object of it refers to a device anti-retraction of the latch (1) comprising a conviction (5), insurance (6), an actuator (7) of said insurance (6), an actuator (8) of said conviction (5) and one or more of said forwarding (9); where, in relation to the vertical operating position of the lock, said sentence (5) has a front front (5a) noticeably vertical, an upper ramp (5b) back ascending, a substantially horizontal upper edge (5c), a oblique window (5d) of variable amplitude and a rear axle (5e) around which this sentence (5) is likely to swing between an inferior, non-condemning position, and a top position, condemnation, and is mounted against a first spring (10) whose elastic load is relatively greater in said non-condemnation position; said insurance (6) has a oblique side (6a) upper facing forward, an appendix front (6b) that is below said oblique side (6a), a transverse projection (6c) running through said oblique window (5d) of the sentence (5) and a lower axis (6d) around which this safe (6) is able to rotate between a forward position, in which said front appendix (6b) appears in front of said box of lock (3) in parallel to said latch (1), and a position rear, in which said front appendix (6b) is retracted in said lock box (3), whose lock (6) is mounted against a second spring (11) whose elastic load is relatively greater in said retracted position; said insurance actuator (7) (6) is jointly attached to said rod (1a) and has a front vertical rear (7a) that faces horizontally with said front front (5a) of the sentence (5); said actuator (8) of the sentence (5) has a guided sliding mount horizontally and has a fin (8a) that is applied on the back of the arm itself (4c) that have such sheet (4a) and nut supplement (4b) (4) to boost retraction of doorknob (1), as well as a transverse stud (8b) that, in relation to these lower positions (non-conviction) and superior (conviction) of said conviction (5), is likely to be located just above said upper edge (5c) of this sentence (5) or horizontally applied on said upper ramp (5b) thereof, respectively. In his said forward position hovering by in front of the lock box (3), said front appendix (6b) of the insurance (6) lacks a corresponding strike in the frame of closing of the lock, is included within the vertical projection of said latch (1) and protrudes in a conveniently larger than the distance between the front of the lock and said closing frame, while its saying transverse projection (6c) is located without clearance at the end higher and narrower front of said oblique window (5d) of a said sentence (5) located in said lower position (non-condemnation) of relatively greater elastic load of said first spring (10), and while said oblique side (6a) of the insurance (6) is distanced from said rear front (7a) of the actuator (7) to a somewhat greater extent than the distance horizontal between said front front (5a) of the conviction (5) and the back of said latch (1). In addition, in his happiness inferior position (non-condemnation) and in relation to said transverse stud (8b) of the actuator (8), said condemnation (5) it is left with its upper edge (5c) just below the level of said transverse stud (8b) and at a horizontal distance of the same less than that existing between said rear front (7a) of the actuator (7) oblique side (6a) of the insurance (6).

The operation of this device anti-retraction is clearly illustrated by the enlarged detail of figure 1 and figures 11 to 13. In the Figure 1, the lock is open (the main lever - 2 - of triple bar is retracted) and the door is separated from the frame; with whatever the handle (1) is out, the insurance (6) is out driven by the second spring (11), the slide (5) is in its lower position (no-condemnation) because he doesn't leave her ascend the transverse projection (6c) of the insurance (6), the front rear (7a) of the actuator (7) of the lock (6) is faced with a small distance from the oblique side (6a) of one's own safe (6), the actuator (8) of the sentence (5) is in position front in which its transverse stud (8b) is a little in front and above the upper edge (5c) of the slide (5). In Figure 11 the door is already in the frame, but before the latch (1) has reached its strike in it and can exit; in this position the rise of the sentence (5) is prevented by the own latch (1), since, when the insurance (6) starts to retract and its transverse projection (6c) releases that movement from the conviction (5), this one finds that the latch (1) had already been retracted until reaching the front position (5th) of it, thanks to said small distance between said front rear (7a) of the operator (7) of the insurance (6) and oblique side (6a) of insurance (6). In figure 12 the latch (1) has already reached its strike and has been able to leave, while the insurance (6) remains retracted by lacking its own locksmith; now the sentence (5) can ascend to its superior position (condemnation) driven by the first spring (10), so that its front front (5a) is slightly behind the latch (1) preventing it from being retracted under the application of a frontal pressure, and its upper ramp (5b) is applied inferiorly and subsequently on said transverse stud (8b) of the actuator (8) of the sentence (5).

In the latch retraction movement (1) when it hits your lock during the free closing of the door, the vertical rear front (7a) of the actuator (7) of the lock affects the oblique side (6a) of the insurance (6) by retracting subsequently and in conjunction with the handle (1).

In figure 13 the retraction has been activated of the handle (1) by means of the inner handle installed in the nut (4); then, the arms (4c) of the nut plate (4a) and of the nut supplement (4b) push on the fin (8a) of the actuator (8) producing its retraction simultaneously with that of the latch (1), with which the transverse stud (8b) acts on the upper ramp (5b) and lowers the sentence (5) so that its front front (5a) is removed when the latch (1) reach its position, this process in which said busty transverse (8b) runs along the upper edge (5c) of the sentence (5) helping to ensure that this sentence (5) remains in its position lower (no-conviction) while insurance (6) returns to its forward position when the door is separated from frame and the action on the inner handle disappears, being thus recovered the position of the mechanism represented in the figure one.

In another order of things the multiple lock of the invention comprises a said forwarding (9) provided with a lever secondary linear closure (12), a first drag piece (13)  and a rocker (14); wherein, said secondary lever (12) is rigidly mounted on a first sheet (15) that has a first vertical slide (15a) as well as a first inclined slide (15b) that, in relation to the output maneuver of said lever linear (12), has initial vertical extensions paths (15c) and final (15d); said first drag piece (13) incorporates a third pivot (13b) slidably located in said first inclined slide (15b) of the first sheet (15) and has a vertically guided sliding assembly between two positions extreme, initial and final, in which said third pivot (13b) it is located, respectively, in said initial extensions (15c) and final (15d); and said rocker (14) has a configuration operative squad formed by a major arm (14a) whose end has a joint (14b) confined in said first slide vertical (15a) of the first sheet (15) and by a smaller arm (14c) which at its end is provided with a longitudinal opening (14d) in which is capable of sliding a first pivot (13a) installed in said first drag piece (13), and whose rocker arm (14) is capable of rotating around a second pivot (16) that is fixed to a corresponding box that houses the mechanism of these forwarding (9), determining two extreme positions, initial or rear and end or front, such that, in said rear position, said major (14a) and minor (14c) arms are respectively vertical and horizontal, said linear lever (12) is inside or outside the forwarding box (9) and said first drag piece (13) is in its initial or final positions. This execution is represented in figures 15 and 19 showing, respectively, the initial or opening and final or closing positions. In the initial position (figure 15) the first drag piece (13) is in its lower position that places its third pivot (13b) in the initial vertical extension (15c) of the first slide inclined (15); while the rocker (14) is in position initial major arm (14a) vertical and placing the first pivot (13a) at the rear end of the longitudinal opening (14d) of the minor arm (14c). In the final position (figure 19) the brace upper (25) has driven the first drag piece (13) with the result that said first pivot (13a) has driven the rocker tilting (14), which has produced the output of the linear lever (12) while the first inclined slide (15b) has been traversed by the third pivot (13b), which has finished placing in the final vertical extension (15d) constituting both pivots (13a and 13b) in resistant elements to the front forces applied on the linear lever (12) are transmitted to the lock mechanism and its braces upper (25) and lower (26).

Another embodiment of the invention in this regard it is the one represented in figures 20 and 21, and comprising a saying forwarding (9) equipped with a hooked lever (17) and a second piece trailed (18); wherein, said hooked lever (17) is rotatably mounted on a second plate (19) provided with three sliders, which are, a second vertical slide (19a), a second inclined slide (19b) which, in relation to the maneuver out of this hooked lever (17), it is equipped with extreme vertical extensions initial (19d) and final (19e), and a sliding horizontal (19c), and whose hooked lever (17) has pivots fourth (17a) and fifth (17b) that are conveniently arranged to different level, said fourth pivot (17a) is confined slidingly on said second vertical slide (19a) and said fifth pivot (17b) is slidably located in said slide horizontal (19c) and around it this hooked lever (17) It is capable of rotating between initial or retracted positions and  final or extended in which this fifth pivot (17b) is located  in respective relative positions front and rear along of said horizontal slide (19c); and said second piece of drag (18) incorporates a sixth pivot (18a) located slidingly on said second inclined slide (19b) of the second sheet (19) and has a guided sliding assembly vertically between two extreme positions, initial and final, in which said sixth pivot (18a) is located, respectively, in said initial (19d) and final (19e) extensions. In this execution the ascent of the second drag piece (18) from its position of figure 20, makes the sixth pivot (18a) travel the second inclined slide (19b) and push the output of the second plate (19), whereby the fourth pivot (17a) is forced to rotate around the fifth pivot (17b) making the hooky lever (17) Tilt to its closed position shown in Figure 21. Also in this case the sixth pivot (18a) fulfills the function of resistant screen against front pressure on the lever hooked (17), when this sixth pivot (18a) is placed in the final vertical extension (19e) of the second inclined slide (19b).

According to another particularity of the invention both executions of said forwarding (9) are mounted on a box that consists of two equal pieces, or half-shells (20), which are mutually coupled to each other in position inverted and each of them has two front tabs, first (21) and second (22), one on each side of said levers linear (12) or hooked (17) and arranged in different planes, of so that said first front flange (21) is tucked with respect to said second front flange (22), and whose tabs front (21) and second (22) have aligned to each other two holes embedded (21a) and (22a) that have threads reciprocals of a mooring screw (23), having the first front flange (21) a tip (21b) embedded in a groove (20a) which belongs to the opposite half (20) and which is located next to the second front flange (22) of this opposite half (20).
