EP3168394B1 - Block for a door opener or a strike plate - Google Patents

Description

The invention relates to a locking block for screwing onto a pivoting latch of an electric door opener or to a lower part of a striking plate according to the features of the preamble of claim 1.

In practice, such locking blocks are used to lock a door leaf of a building door in its closed position via a latch. The latch engages in the locking block and is fixed by this. To compensate for different folding strengths and / or different sealing strengths of a door rebate, it is provided that the locking block is transversely adjustable. This can ensure that the engagement of the latch with the locking block is done so that when the door is closed this is securely held in the closed position. If the locking block is used in a striking plate, there is the danger that the lock catch engages in a gap between the locking block and the striking plate and hooks there in the appropriate position of the locking block.

A generic Sperrkloben is for example from the US 2,439,036 A known. There, a strike plate is described with a screw-on locking block. The locking block can be adjusted by means of slots and has a locking shoulder and an integrally formed on the locking shoulder fixed lock latch guide surface.

The DE 20 2008 009 683 U1 also shows a screw-on locking block for a strike plate. The locking block has a locking shoulder and a lock latch guiding surface.

From the utility model DE 298 01 649 U1 is a door opener with a screw-on locking block known. The locking block has on its outside an apron, which leads a latch. The skirt is beveled and extends from the Sperrkloben obliquely down to a door frame. This apron forms, so to speak, an inlet bevel for a latch.

Object of the present invention is to provide a locking block, in which the risk of catching the latch is reduced to a strike plate. In particular, the locking block should allow in any possible transverse position a safe, in particular hook-free interaction with a latch.

This object is achieved by a locking block with the features of claim 1.

According to the invention it is provided that the locking shoulder has on its outer surface a lock latch guide. The lock latch guide has a lock trap guide web extending in a plane parallel to the base part, wherein the lock trap guide bar is aligned with a front edge of the lock shoulder.

Preferably, the locking shoulder may be integrally connected to the base part. The locking shoulder can protrude from the base part in the direction of a latch. Preferably, the base part clamps together with the locking shoulder on a receiving space for a lock latch. The base part is in
the receiving space opposite the locking shoulder reset or arranged at the back ..

In practice, a latch is acted upon by a spring and strives to exclude a lock housing (firing trap). About an abutment or a support exclusion of the latch can be prevented.

The locking block has a lock latch guide, which forms a support or an abutment for a latch. The lock latch guide is arranged on the catch inlet side of the locking block. This prevents that when entering the lock latch, i. when closing a door, this dips too early in a arranged in front of the locking block gap and hooked there. This allows a clean, trouble-free closing of a lockable door with a lock.

Even when opening a door leaf, the lock latch guide is an advantage. The lock latch guide has a lock latch guide surface or a lock latch guide bar, which protrudes from the front edge of the locking block in the direction of the strike plate and thus prevents a latch case hooking between the outer edge of the locking block and the strike plate in a gap. This also allows a smooth opening process of a door secured with a lock.

The locking block may be formed in one embodiment as an adjustable locking block. Under adjustable is understood to be a transverse adjustment of the position of the locking block on a pivoting latch or a striking plate lower part. To allow such a transverse adjustment of the locking block, is provided in particular that the base part has at least two slots for Querverstellen the locking shoulder. A first elongated hole covers a first transverse adjustment range and a second elongated hole is offset in the transverse direction relative to the first elongated hole and covers a second transverse adjustment range that differs from the first adjustment range. By this arrangement, on the one hand a mechanically stable attachment of the locking block is made possible and on the other hand provided a wide range for a transverse adjustment. In particular, it can be provided that the first slot covers the first transverse adjustment range of approximately 3 mm to 6.5 mm and the second slot covers a second adjustment range of 6.5 mm to 9.5 mm or 11 mm.

Furthermore, it can be provided in one embodiment to increase the mechanical stability that a total of four slots are arranged in the base part. It can be provided that the two middle slots are formed as first slots for covering the first adjustment. The two outer slots may be formed as second slots for covering the transverse adjustment in the second adjustment. So it is possible to attach the locking block always with at least two screws. For the innermost position, the screws are used in the middle position, ie in the middle two oblong holes. By means of a transverse adjustment of the locking block, an adjustment range of 3 mm, preferably 4.5 mm to 6.5 mm, can be covered. If a further transverse adjustment is required, then the screws are converted, ie removed from the middle holes and inserted into the two outer slots. With the attachment in the outer slots now a Querverstellbereich of 6.5 mm to 9.5 mm or preferably 11 mm can be realized.

In a non-inventive embodiment can be provided that the lock latch guide, preferably the lock latch guide surface or the lock latch guide web, is integrally formed with the locking shoulder. Thus, a mechanically robust construction is possible with a cost-effective production of the Sperrklobens.

In order to create a locking block with a universal application as possible, the invention provides that the lock latch guide, preferably the Schlossfallenführungssteg is adjustably mounted on the locking shoulder, preferably pivotally and / or slidably mounted. By adjusting the lock latch guide bar relative to the locking shoulder of the locking block can be easily adapted to local conditions or dimensions.

In order to enable a good lock latch guide over a wide Querverstellbereich of the Sperrklobens, it can be provided that the lock latch guide, preferably the Schlossfallenführungssteg, in an optional angular position is fixed relative to the locking shoulder.

In one embodiment it can be provided that the locking block is used on an electric door opener. The electric door opener has a door opener housing and a door opener latch pivotally mounted therein, which is lockable and releasable via a change cooperating with a drive, preferably with an electromagnet. On the top of the pivot latch the locking block can be screwed.

In one embodiment it can be provided that the locking block is used on a strike plate. Preferably, the strike plate has a lower part which delimits a receiving space for a lock catch. The locking block can be bolted to the base to cooperate with a latch. The strike plate has a receiving space on all sides, i. on four sides enclosing surface, which serves as a guide for the latch bolt. In particular, it can be provided that the locking shoulder extends perpendicular to a receiving space enclosing the surface of the striking plate and the outer edge of the locking shoulder is aligned with this surface.

In order to enable a good transition from the surface of the striking plate on the lock latch guide, the lock latch guide with the receiving space enclosing surface of the strike plate is formed in alignment. Furthermore, the lock latch guide can be arranged perpendicular to the blocking shoulder, or the front edge of the blocking shoulder can be aligned with the surface of the striking plate. A continuous and verhakungsfreier transition of the lock latch from the surface of the striking plate to the lock latch receiving space is achieved by the aligned arrangement of the lock latch guide and the front edge of the locking shoulder.

In particular, it can be provided that the strike plate has a recess for receiving the lock latch guide, preferably that the lock latch guide engages depending on the position of the locking block in the recess. About the recess in the lock plate, the lock latch guide in all transverse positions of the locking block a steady transition of the latch and thus enable a hook-free closing of the door. In the innermost position of the Sperrklobens lies the end of Lock latch guide preferably on the boundary of the surface of the strike plate. If the locking block is moved further outwards, ie the locking shoulder moves further in the direction of the boundary edge of the striking plate, then the lock latch guide can engage in the recess on the strike plate.

In particular, it is provided that the blocking shoulder is arranged at a distance from the edge of the striking plate delimiting the lock trap space, ie. H. is arranged at a distance from the opposite of its outer surface locking plate boundary. Preferably, the locking shoulder can be fastened or screwed on the lower part at a distance from the locking plate boundary opposite its outer side.

In one embodiment, it can be provided that the lock latch guide bridges a distance lying between the blocking shoulder and the locking plate boundary lying opposite this. Preferably, the Schlossfallenführungssteg rest on the one hand to the strike plate boundary and on the other hand on the outside of the locking shoulder.

In one embodiment, the lock latch guide can be mounted on the locking block. For example, the lock latch guide having an arcuate tab which engages in a arranged between the lower part and locking block complementary arc-shaped groove. In this case, the arcuate groove can be arranged either on the base part and / or on the lower part.

In order to ensure a secure fit of the lock latch guide despite easy adjustment, the thickness of the arcuate Tab should be equal or slightly thicker than the groove, so that the locking block when tightening the screw clamped the arcuate tab in the groove.

In one embodiment it can be provided that the lower part is designed as an electric door opener with a pivot latch and the locking block is detachably connected to the pivot latch.

The locking block according to the invention can be used in building doors with different door or door frame constructions. It can be provided that the strike plate is designed as a flat strike plate or as a flap strike plate or as an angle strike plate.

The Fig. 1a shows a strike plate 1, which is designed as a flat strike plate or flap closing plate. In the Fig. 1b is a sectional view Fig. 1a shown along the line AA. The striking plate 1 has on its underside a receiving space for engagement of a lock bolt. Above this receiving space, a second receiving space is arranged, which serves to engage a latch. The striking plate 1 surrounds the lock latch receiving space as well as the bolt receiving space on all sides.

Within the lock latch receiving space 12, a locking block 2 is arranged. The locking block 2 has a lock latch guide 3, which extends from the locking shoulder 22 and has a guide web for a lock latch, which rests against the boundary edge 14 of the striking plate. When closing a door, a latch is opened from the in Fig. 1a shown shown from the right. In this case, the front edge of the latch strikes the surface 13 of the striking plate 1. If the latch when closing the door in the range of Schlossfallenaufnahmeraums 12 comes, it leaves the surface 13 of the strike plate and passes directly to the lock latch guide 3 and the lock trap guide bar 31, which in the Figures 3 or 6 is shown in more detail. When closing the door, the tip of the latch first slides on the surface 13 of the striker plate 1, then comes into contact with the lock latch guide bar 31 and slides on this back to Trap receiving space behind the locking shoulder 22.

From the Fig. 1b is the alignment of the front edge 22k of the locking bolt 2 with the surface 13 of the striking plate 1 clearly visible. The lock latch receiving space 12 is formed by the base part of the locking block 2 and the inner surface 22i of the locking shoulder 22. The locking block 2 has an approximately L-shaped cross-section. The base part 21 is integrally connected to the locking shoulder 22. The outer side 22a of the locking shoulder 22 is located opposite the boundary edge 14 of the striking plate at a distance. Between the outer surface 22a of the locking shoulder 22 and the boundary edge 14 of the strike plate, the lock latch guide 3 extends with the lock catch guide web 31. The lock catch guide web 31 bridges the distance between the outer surface 22a and the strike plate 14.

In the FIGS. 2a and 2b is a not erfindunggemäße variant of the lock latch guide 3 is shown. Instead of an articulated on the locking shoulder 22 Schlossfallenführungsstegs 31 has in the FIGS. 2a and 2b shown embodiment, a lock latch guide surface 33 which is integrally formed with the locking shoulder 22 of the locking block 2. The lock latch guide surface 33 is in alignment with the front edge 22 k of Locking shoulder 22 and the surface 13 of the striking plate 1 is arranged as out Fig. 2b is apparent. The Fig. 2b again shows a sectional view along the line B - B of Fig. 2a represents.

Also in this embodiment, a latch bolt slides in turn first on the surface 13 of Lappenschließbleches 1 along and then passes to the lock latch guide surface 33. On the lock latch guide surface 33, the latch then slides past the inner bearing surface 22i of the locking shoulder 22 into the receiving space 12 inside.

When the door is opened, the latch is pulled back over a door handle and then comes to release the door handle and pivoting the door first with the surface of the lock latch guide 33 in contact. Upon further opening of the door, the latch bolt then slides along the lock latch guide surface 33 and is directly, d. H. directed in a line on the surface 13 of the strike plate 1. Thus, a catching of the lock latch is prevented in a present between the closing plate boundary edge 14 and locking shoulder 22 gap.

In the Fig. 3 an enlarged view of the locking block 2 in a striking plate bottom part 11 is shown. The lower plate member 11 is bolted to the strike plate from the back and can be removed from this. The lower plate member 11 has three walls, which are interconnected via a bottom part. The locking block 2 is bolted to the bottom part of the lower part 11 and can be adjusted transversely to its longitudinal extent by means of the screws 23. For transverse adjustment of the locking block 2 four slots 241, 242 on. The middle slots 241 cover thereby a first adjustment range. The outer slots 242 cover a second adjustment range.

At the in Fig. 3 right side of the lock latch guide on the outer surface 22a of the locking shoulder 22 is arranged. The lock latch guide 3 has a lock latch guide web 31, which extends at an angle to the locking shoulder 22. The lock latch guide 3 is mounted on the locking block 2 pivotable and displaceable. Thereby, the angle between the locking shoulder 22 and lock latch guide web 31 can be adjusted to bridge different gaps between the locking shoulder 22 and lock case edge 14.

In the Fig. 4a the locking block 2 is shown in its outermost transverse position. In the outermost transverse position, the locking shoulder 22 bears against the closing plate boundary edge 14 with only a small distance. The lock latch guide 3 or the lock catch guide web 31 runs parallel to the blocking shoulder 22 in this position.

In the Fig. 4b the locking block 2 is shown in its innermost transverse position. In this position, the strike plate 1 between the locking shoulder 22 and closing plate boundary edge 14 has a relatively wide gap. By pivoting the lock latch guide 3, this gap can be bridged. Even with every possible intermediate position of the locking block 2 between the outermost position of the Fig. 4a and the innermost position of the Fig. 4b can be adjusted by pivoting the lock latch guide 3, the required distance to allow a friction-free lock latch guide. The pivoting of the lock latch guide 3 via a combined pivot bearing, as in the FIGS. 5, 6 and 7 shown. The Fig. 5 shows the lower part 11 of the striking plate with a groove 32. The groove 32 is arcuate and complementary to a tab 34 of the lock latch guide 3 is formed. As in Fig. 7 is shown, the arcuate tab 34 of the lock latch guide 3 engages in the groove 32 in a form-fitting manner. By correspondingly deep insertion of the arcuate tab 34 in the arcuate groove 32 different pivot angle of the lock latch guide 3 and the Schlossfallenführungsstegs 31 can be adjusted relative to the locking shoulder 22. The fixing of the lock latch guide 3 in a set position takes place by tightening the screws of the locking block. As a result, the base part 21 of the locking block 2 presses from above on the tab 34 and fixes it within the groove 32.

As in Fig. 6 illustrated, the lock latch guide 3 is formed as a folded metal part. The lock latch guide 3 has a planar body with a lock latch guide web 31. On its underside, the lock latch guide 3 an arcuate tab 34 which is bent by 90 °. In the manufacture of the lock latch guide 3, for example, from a flat metal sheet by punching or cutting a the outer contours of the lock latch guide 3 corresponding part can be separated. By simply folding the curved tab 34, the lock latch guide 3 can then be produced.

In the Fig. 8 is a not inventive variant of the locking block 2 is shown. The locking block 2 corresponds to the in the FIGS. 2a and 2b shown locking block. Unlike in the FIGS. 1a and 1b has shown locking block this locking block 2 on its locking shoulder on a lock latch guide surface 33 which is integrally formed with the locking shoulder 22. The lock latch guide surface 33 is formed as a nose, which is arranged in alignment with the front edge 22k of the locking shoulder and projects from this outwardly. Incidentally, the equivalent in the Fig. 8 illustrated locking block 2 the Sperrkloben, in the FIGS. 1a and 1b and 3 to 4b illustrated locking block.

Both with the in the FIGS. 1a, 1b and 3 . 4a and 4b illustrated locking block as well as with the locking block of Example 2a, 2b and 8, a comfortable and hook-free lock latch guide is possible in a large Querstellbereich the Sperrklobens in any position.
