Invention field

The present invention relates to a kind of latch box linkage, relate in particular to a kind of fixture that is used for the latch box, this latch box joggle or will joggle to block plate (for example the latch box being called " joggle latch box " here) in.The invention still further relates to this fixture and the assembly that suitable keeper is assembled, and a kind of latch box that cooperates with this fixture.

The present invention finds that maximum use is that described door installs on the fixed frame, so the description of back relates generally to this purposes in order to resemble the articulated slab joggle latch box of door one class.But, two portable plates be fixed together and/or fix a suitable sliding panel also within the scope of the present invention.

Prior art

Joggle is known to the latch box in the door-plate.Usually, having one on the box can carry out movable latch with the driver that is contained in this box, and this latch is movable between extended position and punctured position.Driver can be by handle or thumb wheel (being positioned on the surface of door) operation, and/or one partly or entirely by the arrestment mechanism operation that is arranged in this box, has one to make the surperficial keyhole that is communicated with of box and door, so that key is inserted arrestment mechanism.The latch that is in extended position stretches out (or stretching out the joggle groove from door) from box, this latch and keeper engagement, and described keeper is contained on the framework.

Traditional joggle latch box has the latch of a head substantially flat usually, but the latch that also has some to have the band hypotenuse, and this latch can automatically mesh with keeper, thereby when plate is made closing movement, just plate can be maintained on the framework.

The problem of joggle latch box (the latch box that also has other form) is to be intended to the intruder can be separated plate and framework or they be pried open by force, thereby latch on the keeper or latch are unclamped.In case in this way plate is applied power, just can pass through latch or latch open plate like a dream.

Disclose a kind of latch element that is used to prevent or reduce this power of forcing in my patent application WO97/01690, this latch element is as the surface of installing onboard.In this application, a kind of latch element with a box is disclosed, this latch can stretch out from described box, has a receiver on the box.This latch moves in two stages, near the phase I latch moves to receiver, moves to receiver at the second stage latch.When latch was in receiver, keeper was connected with latch effectively, thereby stoped or prevented to force plate to leave the power of framework.

Summary of the invention

The present invention aims to provide a kind of latch box linkage, and this latch box linkage cooperates with an existing or new joggle latch box, so just can acquire benefit from " receiver " function of my application.Specifically, latch box linkage provided by the invention can install on the joggle latch box, also can install to the inside and be provided with on the plate of existing joggle latch box, so that increase the unauthorized power that makes plate leave framework that resists.

So, according to the present invention, a kind of latch box linkage is provided, the latch box has a latch, and this latch moves between punctured position and extended position along its y direction, and described latch box linkage has a fixed head and a lockplate, described lockplate has a wall, under its elongation situation, the part of this wall and latch is arranged side by side, and described lockplate separates along its y direction and fixed head.

Described lockplate preferably also has another wall at least, and arranged side by side in the part of this wall of extended position of latch and latch, described wall and described another wall preferably link together.More satisfactory is that four walls are arranged, and the part of these walls and latch is arranged side by side when the extended position of latch, and four walls limit a groove or hole together, and when latch moved to its extended position, the part of latch entered or by this groove or hole.Therefore, the distance that lockplate and fixed head separate substantially can be identical with the stroke of latch, and the trip is defined as the distance of latch between punctured position and extended position.In addition, distance that should be separately can be less than the stroke of latch, thereby makes latch make its termination pass through lockplate when extended position.

In most of the cases, latch when its punctured position, the termination of this latch can with the flush of latch box, the stroke of the latch ultimate range that can stretch out from the surface of latch box of latch just like this.In addition, in use, the surface of latch box usually can flush with the side of plate, thus the stroke of latch usually corresponding to this latch can slave plate the side ultimate range of stretching out.

Preferably fixed head directly is fixed on the latch box, also can it be fixed on the latch box indirectly by the side of plate.Because the distance that the side of lockplate and plate separates in assembling process can be greater than the stroke of latch, so at the extended position of latch, the part of this latch can enter lockplate, and might stretch out by this lockplate.

But lockplate makes the part of keeper enter between the side of lockplate and plate with the distance that fixed head separates, and a hole that is used to receive the part of latch is arranged on the part of described keeper.Therefore, when assembling fully finishes when going forward side by side line operate, latch can extend, by the hole of keeper, with the wall of latch box linkage the hole of lockplate by latch box linkage (also can enter or) side by side; After this latch that utilizes latch box linkage and this latch box linkage is connected with keeper just can stop and attempt power that plate is thrown off from framework without approval.

According to a further aspect in the invention, a kind of composite member that comprises a latch box linkage and a keeper is provided, linkage and keeper are respectively as the accessory of plate and framework, latch box linkage has a fixed head and a linkage lockplate, the plane of linkage lockplate and the plane of fixed head separate, keeper has a keeper lockplate, its thickness is less than the distance between each linkage plate, the position and lock plate has a hole that latch is installed, and the linkage lockplate has a wall arranged side by side with the part of latch.

According to a further aspect in the invention, provide a kind of method that improves the safety of plate in its framework, the method comprising the steps of: (1) obtains the latch box linkage that a this paper limits; (2), with latch box linkage or be fixed on the joggle latch box, perhaps be fixed on the plate side adjacent with joggle latch box with the wooden partition of a lockplate that aligns with latch of latch box linkage; (3) keeper is arranged on the framework, this keeper comprises a lockplate that has the latch installing hole, and the installation site of keeper makes and to be in when closing situation when it that latch installing hole aligns with latch.

The description of embodiment

In this embodiment, plate 10 is exactly a door, utilizes hinge 14 to be mounted on the framework 12 with known method.Framework 12 also is fixed on the wall 16 with known method.

Have the joggle latch box of a joggle in the door 10 on the plate 10, this latch box is adjacent with the side 20 of door, so can not see among Fig. 1.In this embodiment, joggle latch box 30 has a latch and a latch, and described latch is operated with handle 22, and latch is operated with the key operated mechanism of key engagement in the box and that insert keyhole 24.According to known method, keyhole 24 is contained in the door 10 lip-deep thread escutcheons 26 at one.

In Fig. 2, be shown in broken lines joggle latch box 30 (so because it joggle in door, can't see).According to known method, the face 32 of joggle latch box 30 aligns substantially with the side 20 of the locking edge (the locking edge here is defined as the limit opposite with hinge edge) of door 10.Latch 34 can stretch out from joggle latch box 30, also can be from the side 20 stretches out, and the ultimate range of stretching out is t; As shown in the figure, latch 34 is in extended position, promptly extends the longest or outstanding the longest from joggle latch box 30." stroke " of distance " t " expression latch 34, it is determined by the structure of each member at joggle latch box 30 edges according to known method.

Latch box linkage 40 is fixed on the side 32 of joggle latch box 30, this latch box linkage comprises a pair of fixed head 42a and a 42b and a lockplate 44 (seeing clearlyer among Fig. 4).Fixed head 42a has pin hole or screw hole 46 (preferably immersing oneself in) on the 42b, fixed head 42a, and 42b (also having linkage 40) is fixed on the side 20 by these holes.In another embodiment, can also can fixed head directly be fixed on the joggle latch box 30 with screw rod or latch by welding.

A hole 50 that is made of wall 48 and other three connecting walls (not illustrating with label) is arranged on the lockplate 44.The size in hole 50, shape is identical with latch 34, and aims at (when assembling according to the mode of Fig. 2) with latch 34.A size is arranged on the fixed head 42b, and shape and latch 54 are identical and aim at the hole 52 of (when assembling according to the mode of Fig. 2) with this latch.

In further embodiments, have only a fixed head that is connected with the cantilevered lockplate, but these embodiment are not best.

In fact, as shown in Figure 2, fixed head usually according to service orientation be positioned at the top of lockplate and below, it has utilized the maximum vertical size of door, this fixing irrelevant with on the little horizontal dimension of side 20; But, when door is thicker, add a fixed head or polylith fixed head, they are separated to each other in the horizontal direction.

Lockplate 44 and fixed head 42a, 42b interconnects by connector 56, and connector is substantially parallel with the longitudinal axis A-A of latch 34 in this embodiment.

The plane of lockplate 44 and fixed head 42a, the distance that the plane of 42b separates is s, and this distance is less than the stroke t of latch 34, and therefore as shown in Figure 2, when latch 34 moved to its extended position, it just entered in the hole 50 of lockplate 44.

When door was in fastening position shown in Figure 2, position and lock plate 60 was between the lockplate 44 and side 20 of linkage.Fig. 3 can see clearlyer, and position and lock plate 60 is integral parts of keeper 62, and 64 vertically stretches out from the bottom.

Position and lock plate 62 has an opening 66, the lockplate 44 and the connector 56 of linkage 40 can be installed in this opening.Position and lock plate 62 has a wall 70 round opening 66; This wall 70 is connected with bottom 64, thereby makes the structural strength of position and lock plate bigger.

It should be understood that latch 54 is not that the latch box is necessary, and it can install on existing many available joggle latch boxes.So, require locking mechanism and keeper can adapt to this latch.Therefore, as mentioned above, fixed head 42b has an opening 52, and latch stretches out by this opening, with the hole 72 engagement lockings of keeper.

With the known method latch 54 of cutting sth. askew, like this when door moves to fastening position, this inclined-plane (not shown) is thrown off the surface 74 of keeper, the surface 74 of keeper is used for latch 54 is pushed back in the joggle latch box 30, according to known method, when latch alignd with hole 72, it just rebounded from the latch box.

In further embodiments, fixed head 42b can bump less than latch, therefore it does not just need to be provided with the hole, but, for the joggle latch box that is applicable to latch, preferably fixed head extends to outside the latch, can improve the intensity (in fact because the distance between latch and the latch is very little usually, it is following to be about 2cm) of linkage like this.

As mentioned above, fixed head can directly be fixed on the latch box by welding, and is this fixing seemingly only for the accessory as original equipment.This fixed head can be fixed on the new or old latch box by screw rod or latch in addition, but this need process suitable screw in the latch box.In addition, fixed head can extend to the outside of latch box, thereby can directly be fixed to the side of plate, and this embodiment with Fig. 2 is identical.

Obviously, compare with the locking device of the prior art that needs quite little notch (corresponding to the size and the stroke of latch 34) in the framework, utilize locking mechanism of the present invention, require bigger notch that bigger keeper (the specifically end 64 and wall 70) is installed.But, should believe that the material of removing increase can have any loss to the intensity of framework hardly, the material of removing is compensated by the keeper that increases intensity.

Positioning and fixing plate 76 is arranged on the keeper 62, countersunk hole or pin hole 78 are arranged on this fixed head, utilize this hole keeper can be fixed on the framework 12.The latch or the screw rod (not shown) that are used for keeper 62 is fixed on the framework 12 can be microscler, so just can enter wall 16 by framework 12 fully, prevent that keeper 62 from moving thereby have very big resistance.

Position and lock plate 60 has a plurality of (having four among this embodiment) connecting wall 82, according to known method, these walls limit a hole 80 that can allow latch 34 pass through together.

The latch box, linkage and the keeper that install for operational group finish in case these parts are assembled in the manner described above, and door 10 just can move to its fastening position.In this case, align with the locking plate hole 50 of linkage in the hole 80 of position and lock plate, and align with the mobile route of latch 34.Latch 34 is by the hole 80 of position and lock plate and the locking plate hole 50 of linkage then, move to its extended position (Fig. 2), after this, prevent that door 10 from moving the joggle latch box of resistance ratios prior art of (for example using grab iron) and the resistance of keeper device improves greatly.

Because fixed head (especially for the linkage of existing latch box) must be assemblied in the slit between side 20 and the framework 12, so require the size of this plate less (along the direction of axle A-A); But, require the thickness of fixed head just suitable intensity can be arranged greater than 2mm, so just can satisfy most requirement, and in most of the cases, also thickness can be assemblied in the slit between side 20 and the framework 12 greater than the fixed head of 5mm.

In addition, if the slit is too little can not the mount plate time, then can slot to framework as required.Also can open the groove of mounting plate in the side, have only lockplate and connector to stretch out the side like this, these connectors just can be assemblied in the suitable groove of opening on the framework.

All more than 14mm, it is 12mm that some strokes are also arranged certainly to the latch stroke of present most of joggle latch boxes; But the law of European Union tries hard to make the standard stroke of the latch of joggle latch box to fix on 20mm or 25mm.Make linkage be applicable to great majority or whole available joggle latch box, even adopt above-mentioned minimum stroke, also the 5mm of keeper can be assembled between the lockplate of side and linkage by thick lockplate, and still latch can be contained in the hole of linkage lockplate.Obviously, adopt the long joggle latch box 30 of stroke, just can between the mutual moving component of keeper and locking linkage, leave bigger gap, and can not influence its intensity.

Though be described being contained in door in the framework or the joggle latch box (normal appts) in plate and the keeper, be understood that also can with they the position conversely.

It will also be appreciated that the present invention can be used for other plate, window for example specifically is used for the window that is made of plastics of hollow shape, and known these windows are equipped with as the joggle latch box of locking mechanism and/or sliding latch.

In illustrated embodiment, the stroke t of latch 34 makes the end of latch by hole 50 (Fig. 2) when latch is in extended position.But in further embodiments, the stroke of latch is less, we can say that also the distance between lockplate and the fixed head increases, and makes the end of latch not pass through lockplate.In this class embodiment, lockplate just can have the notch that the latch end is installed, rather than the hole of being passed through by the latch end.

In addition, should be understood that,, as shown in Figure 2, will apply a power for from the outside plate 10 usually when attempting that without approval the plate on the framework 12 10 is prized following time.Under the effect of this sled power, only porose 50 wall 48 and latch engagement (because the hole 80 of keeper will make latch overcome sled power); Therefore, lockplate may include only wall 48, but also will overcome this sled power.But, if having an opportunity from top and/or below skid plate 10 (as shown in Figure 2), then need to be arranged alternately the wall of lockplate and/or increase this wall, preferably the wall that increases is connected to wall 48.Obviously, although might not need to have the hole or the groove (for example the hole 50) of four connecting walls, this configuration is more satisfactory, because it has increased intensity, and the outward appearance of product is also very beautiful.

In addition, owing to be in the back that the situation lower connecting device lockplate 44 of closing is positioned at position and lock plate 60 at plate, therefore utilize the engagement between linkage lockplate 44 and the position and lock plate 60 just can prevent skid plate, in case and skid plate will make the side 20 of plate and the gap between the framework 12 increase (when for example attempting to unclamp latch from the locking plate hole 80 of keeper).

In another embodiment, the lockplate linkage can comprise a cover plate that is fixed to the upper, thereby covers the position and lock plate in use.Suppose that in the embodiment shown in Figure 2 plate 10 opens wide to the observer just can be equipped with upper cover plate, so just can cover the part between the connector 56, covers the major part of the lockplate 60 and the latch 34 of keeper.This cover plate makes that the outward appearance of assembly is more beautiful, and is in when closing situation when plate, also can prevent to touch position and lock plate and latch, and contact position and lock plate and latch are to attempt open plate under not licensed situation.
