In case of an unauthorized attempt to release the lock by bending the lock panel (18) on the door frame outwardly so as to cause the latches to move in the direction of the frame, the vertically projecting pins within the inside of the case will abut against the lock panel on the lock side and prevent movement of said latches.

Description

The reinforcement pins of the hook-shape latch of safety lock

Technical field

The present invention relates to a kind of lock, be specifically related to a kind of door lock with the hook-shape latch that demonstrates improved security feature.

Background technology

The lock of high security feature being provided, that is to say, have the lock of the hook-type twin-lock door bolt in the suitable groove that is bonded in the door frame, is well-known in safety lock manufacturing field.The advantage of above-mentioned lock is, when sealed, they provide multiaxis sealed simply, to keep out and to steal vertical and power level relevant and generation during attempting theft of attempting complete.

Can provide many pieces of patent documentations at this, wherein disclosed lock all has the hook-shape latch that rotates by one group of axostylus axostyle that is driven by actuator mechanism.Wherein, one of obtainable patent/patent application of the public is the italian patent ITTO20000226 that licenses to Tesio S.r.l.This patent disclosure with the hook-shape latch lock bar slot interlocking, that have the curved convex form that is positioned on the lock panel.Described curvilinear latch is rotated via the axostylus axostyle that is connected to it.The rotation of the axostylus axostyle that is caused by actuating mechanism realizes that by displaceable element displaceable element control is combined with the arm of suitable pivot, thereby makes described spindle rotation, and therefore makes described curvilinear latch rotate.

The difference of content disclosed herein and obtainable prior art is that it has following feature, has promptly designed special structure, to stop specifically at by destroying its rotating mechanism the theft of hook-shape latch inefficacy being attempted.Though having that the lock of this class lock bolt compares with the linear latch of routine is favourable basically, still there is some weakness in they.

Using various technology to remove door lock in theft is attempted is well known fact.A kind of in these technology adopts worm screw (being similar to the worm screw of jack), is fixed to the screw that can not vertically move when rotating.Therefore, in case be fixed on the both sides of door frame in the position that is parallel to a surface, it will keep static, and force door frame towards the curvature of space of portion outdoors.This may make finally that framework bends to the degree that hook-shape latch reaches its ultimate strength, thereby its hook-like ends breaks through the line that limits outside gib head, perhaps rotating dog tears the panel that certain distance reaches lock one side with the lock latch actuator pin that leads by the thin slice with described lock housing side on lock bolt, thereby trend towards moving forward along the framework direction, wherein said curvilinear latch is rotated and is installed on the described rotating dog, and is fixed to therewith on the side thin slice of lock housing.Under latter event, described rotating shaft rod and the actuator pin that is directed to may fracture.

In both cases, on the other hand, all security features of door will become in fact inoperative, because lock bolt will no longer be bonded in the groove on the lock panel of frame side under no hook-type situation partly, perhaps lock bolt will be no longer fixed by rotating shaft rod or the actuator pin that is directed to.

Typically the several somes place in lock housing is fixed to one another for several independent assembly in the wall of lock housing one side and the lock hardware.The pin that is positioned on the pivot center of hook-shape latch also is fixed on the sheet material side wall.This point especially occur as the situation of the illustrational theft trial of previous institute under become an important disadvantages.Along the axis of pitch of door, the linear tension that on the door frame direction, produces, especially need hook-shape latch to resist the outside power that on the hook end, causes by worm screw.

When theft took place, the hook end was positioned at the position of the groove interlocking on the lock panel with frame side.The latter is made by firm material, and in most of the cases can not fracture.Yet along with the rotation of worm screw, it will trend towards outwardly-bent, and the groove on the panel will be deformed to the degree that occurs the space between lock one example and frame side panel together with the hook end of interlocking with it.

By selecting suitable material can prevent gentle the breaking of hook-type lock bolt of separating.On the other hand, suppose that the outside hook portion of hook-shape latch can be selected resist to fracture because of suitable material, then breakaway force will act on the axostylus axostyle and the hook-shape latch actuator pin that is directed on.In case not being the integrality of maintenance system and opposing external force but the rotational pin of forming system's center of rotation, its major function do not fracture, hook-shape latch will at first unclamp with the thin slice of lock housing side and contact, and by the certain damage on the actuator pin that is directed to, lock bolt is fixed to actual becoming freely and no longer on the lock housing.

The present invention solves above-mentioned particular problem by utilizing lock panel, and wherein lock panel is made by sturdy material and is suitable for resisting and will causes lock bolt to move to power outside its predetermined farthest limits position, and this point will become apparent in part subsequently.

Goal of the invention

Main purpose of the present invention is to provide a kind of door lock with high security of hook-shape latch, and outwards moving of hook-shape latch remains in the predetermined scope, and lock bolt can not leave lock housing.

Summary of the invention

The invention provides a kind of safety lock, it comprises conventional slide bolt and one group of independent hook-shape latch with curved convex form, described hook-shape latch with door frame on the mode co-operate of suitable lock bar slot interlocking.According to the present invention, described curvilinear latch additionally is provided with from its side surface, with a plurality of pins of the vertical projection of any one mode towards the thin slice of case side.Exist by the outwardly-bent lock bolt that makes of lock panel on the door frame is moved along the direction of framework, thereby remove under the situation of the unauthorized trial of locking, the pin of the vertical projection of enclosure interior will and prevent that described lock bolt from moving against the lock panel of locking a side.

The specific embodiment

Referring now to above-mentioned accompanying drawing, generally comprising among Fig. 1 a: a plurality of lock bolts (12,13 and 14) by 11 lock sets of representing, described lock bolt can move in the following manner with respect to described assembly (11), that is, it is engaged in the suitable groove (15,16) on the lock panel (18); Actuator mechanism is used for described a plurality of lock bolts are switched between sealed and non-latched position; And last but be not unessential transmission mechanism, it transmits motion to described a plurality of lock bolt (13,14).

According to the present invention, except the slide-and-lock bolt (12) of routine, also adopted one group of independent hook-shape latch (13,14), described hook-shape latch has the form of curved convex, and explicitly with integral way operation, thereby with the lock panel that is positioned at frame side (20) on suitable lock bar slot (19) interlocking.Described curvilinear latch (13,14) is designed to co-operate and rotates via the axostylus axostyle that is connected to it (21).Hook-shape latch (13,14) is designed to have curvilinear sides in the outside of head by convention, and head extends internally with the form of right angle corner, and in the turning, forms the space between two pieces.One in these pieces is actually head, and it joins in the groove (19) on the lock panel (20).

Controlled by the handle hub with spring-loaded form of structure by convention according to linear slide bolt of the present invention (12), handle hub is activated by handle, and described handle makes the mechanism that transmits motion to the spring-loaded structure rotate.The actuator mechanism of linear bolt (12) and transmission mechanism thereof are extensively to adopt in the art, thereby need not to be described further at this.Bolt (12) is conspicuous with respect to the state of handle hub to those skilled in the art.

For curvilinear latch (13,14), realize the rotation of axostylus axostyle (21) by actuating mechanism, thereby make curvilinear latch (13,14) motion, wherein by key being inserted in the lockhole (22), start actuating mechanism in the mode that advances the pivo table member (not shown), rotating element control is suitable for being bonded on the arm in the groove (22), to advance the described actuating mechanism of curvilinear latch (13,14).The function of lock tube is conspicuous to those skilled in the art.The actuator devices that is used for lock bolt (13,14) comprises the unidirectional slide (25) of linear steering usually, and slide (25) has two clamping limbs (29) of the center of rotation (21) of the lock bolt of extending to (13,14).

According to the present invention, curve lock bolt (13,14) is designed to provide individual pen (single-turn) 90 degree displacements, to guarantee to join to the bonding station in the panel slot (19) in a circle rotates.Can make axostylus axostyle (21) and a pair of king pin (23) that in lock bolt (13,14), leads rotate the rotation in lockhole (22) of suitable key, thereby described lock bolt (13,14) is rotated.In the described pin (23) each all depends on the joint and the separation point position of described lock bolt (13,14), and is driven by front and back between two edges of guide groove (24 among Fig. 2).Described king pin (23) causes curvilinear latch (13,14) to realize that in opposite mode 90 degree of complete step slide with being synchronized with the movement of described axostylus axostyle (21).

Can explain being synchronized with the movement of described king pin (23) and described axostylus axostyle (21) from the structure of each clamping limb (29) of unidirectional slide (25) extension of described linear steering by reference.For this reason, each clamping limb (29) that extends to each lock bolt (13,14) comprises open end recess, admits described axostylus axostyle (21) with side direction, and the bottom surface of described axostylus axostyle (21) is fixed to and is arranged in the suitable groove of lock housing sidewall (28) on one of at least.When sealed, except the openend of recess, axostylus axostyle (21) is surrounded fully complete, and wherein the openend of recess preferably limits moving of axostylus axostyle.

The described recess on each arm, also be provided with the groove that is used for vertically holding described king pin (23), and only allow described king pin in described guide groove (24), to carry out limited linearity to move.Cause moving of the mobile described king pin of lock bolt (13,14), directly be subjected to the influence of described clamping limb (29), because king pin axially is placed in the groove and lock bolt groove (24) of clamping limb (29).Beginning in sealed process, each clamping limb (29) advances on the contrary, so that described king pin (23) slides into the limit of groove (24), and the further propelling of clamping limb (29) makes king pin (23) that lock bolt (13,14) is carried into complete latched position around each center of rotation (21).When king pin (23) suitably was not advanced into farthest extreme position in the guide groove (24), it was impossible realize that individual pen 90 degree of lock bolt (13,14) move.In other words, rotation is to realize that by oblique the moving of king pin (23) in groove (24) groove (24) tilts with respect to the direction of lock panel (18).Center of rotation (21) is positioned this fact on the direction of oblique groove (24), provides effective individual pen 90 degree to slide.In center of rotation (21) is not in the optional design that directly is positioned on the longitudinal direction of groove (24), and effectively to rotate fully be impossible in single step.

---wherein use worm screw, along the direction of door frame, come crooked lock panel (20) in the mode of exerting pressure on the safety component (for example king pin (23) and axostylus axostyle (21)) of the most critical of lock---the invention provides one group of special structure and makes king pin (23) and axostylus axostyle (21) away from responding to component for the theft of describing type before preventing is attempted.Therefore, described curvilinear latch (13,14) additionally is provided with a plurality of pins (26), and described pin (26) is from lateral vertical projection in latched position remains on lock housing, body part.If attempt by making the lock panel (20) on the door frame outwardly-bent without approval, so that lock bolt (13,14) moves along the direction of door frame, thereby remove lock, the pin that is positioned at the vertical projections of lock housing inside then will and stop the displacement of described lock bolt (13,14) against lock panel (20).

Reinforcement pins (26) be prevent to contact lock panel (20) with any trial thus make the outwards direction of door frame (promptly along) first barrier of sliding of described lock bolt.Because reinforcement pins is vertically imbedded lock bolt (13 in the mode of safety, 14) in the body, and the head of reinforcement pins surpasses lock bolt (13 slightly in the mode that lock panel (20) part with lock bar slot (19) outside forms enough contact surfaces, 14) surface, therefore can make whole lock bolt (13 by lock bar slot (19), 14) body stops to move, and opposing otherwise is applied to the outside power on king pin (23) and the axostylus axostyle (21).

Consider the latched position layout of lock bolt (13,14), reinforcement pins (26) is positioned to basic near lock panel (20).In other words, reinforcement pins (26) arrives the radius of the distance of lock panel (20) less than reinforcement pins (26) self.Or rather, point on the reinforcement pins (26) and the minimum range between the lock panel (20) are less than the radius of reinforcement pins (26) self.

According to the present invention, reinforcement pins can also be installed in the far-end of lock bolt (13,14) for lock panel (20).Fig. 4 shows this pin (27).

This pin (27) of projection symmetrically from two surfaces of curvilinear latch (13,14) will further postpone moving of lock bolt (13,14).Country at the applicant place is known that along with in single increase of locking the time of consumption, the risk that the robber removes the lock with high security fully sharply descends.
