Definitions

  • the invention relates to a door lock to be fastened with a lock cylinder-actuated lock bolt and a cooperating, to be attached to the door frame lock box, on which a hinged out of the door locking bracket is attached, which has a longitudinal, all-round closed locking slot, which in the extended position of the Riegel from whose head is provided with cut-in cuts to penetrate transversely and reach behind.
  • Box locks of the above type are known for example from DE-GM 74 40 155 and DE-OS 37 21 670.
  • the locking bracket which can be folded out on the lock box, allows the door leaf to be locked in the gap opening position in connection with the extended lock bolt reaching into its locking slot so that the apartment owner in question can recognize and speak to the person standing outside the door, the latter
  • the apartment owner would have to close the lock bolt by actuating the inside handle or occasionally an internal lock cylinder instead, so that the bolt head can move out of the locking slot of the locking bracket and thus release the door leaf for further opening.
  • the door leaf is an essential prerequisite that the locking slot penetrated and engaged by its head in the extended position of the lock bolt is closed all around, so that the latter is also securely guided in intermediate positions of the only partially gap-opened door leaf and it does not result in the bolt head being extended from the locking bracket Lock slot is coming.
  • both the inside and outside users of the door equipped with such a box lock must differentiate between the two locking positions, for which purpose a special status display is usually necessary on the inside of the door. Also, after each door wing is fully open, the lock bolt must be extended into its intermediate position, if one wants to have ensured the gap opening position of the wing, but this can be forgotten.
  • the invention is therefore based on the object of improving and perfecting a box lock of the type mentioned at the outset in such a way that it is structurally simpler and can also be manufactured more easily, but is also still considerably more user-friendly.
  • a box lock of the type in question in that the lock box laterally next to the locking bracket and below of its folding bearing and the bolt head movement path, a locking slide which is adjustable transversely to the locking bracket is provided, which projects laterally into the locking slot in the hanging position of the locking bracket and thereby blocks the locking bracket against folding out, but can be disengaged from this blocking position by an actuating button attached to it on the outside.
  • the locking slide advantageously has a blocking end provided with a bevel on one side and is under the action of a spring which seeks to push it into the blocking position.
  • Such a box lock is of a comparatively simple nature, since it only requires a lock bolt which can be extended only in one direction and a tumbler which locks it either in the retracted or extended position. In the extended position of the lock bolt, it engages with its head behind the locking bracket, which is in its usual hanging position but is blocked by the inserted locking slide, as a result of which the door is properly locked.
  • the inside of the door only needs to be disengaged from its blocking position by operating the actuating button, as a result of which the locking bracket is released and, when the door is opened, is folded out by the attacking lock bolt.
  • the trap-like, one-sided beveling of the blocking end of the locking slide ensures that when the door is closed from the gap opening position, the pivoting locking bracket automatically reaches its blocked hanging position on the lock case.
  • the user-friendliness of the new case lock also manifests itself in the fact that the person wishing to pass through the door from the outside only needs to differentiate between a single locked position and the release position of the lock when the outer lock cylinder is actuated, i.e. unlock the door with a single turn of the key in any case can
  • the lock box advantageously consists of a die-cast piece which has a top part, which is essentially U-shaped in plan view, with bearing bores in its U-legs for receiving the hinged hinge pin of the locking bracket on the one hand and the locking slide on the other hand and one-sided to this has protruding bottom part protruding toward the locking bracket, in which There are screw fastening holes in the lock box, which are to be covered by the locking bracket above. In this way, the fastening screws of the lock case are only accessible in the open position of the case lock, in which the locking bracket can be folded down. A multi-part construction of the lock box can therefore also be dispensed with.
  • the two bearing bores in the lock case are advantageously identical for the optional installation of the hinged hinge pin of the locking slide necessary for its right-left use.
  • the locking of the case lock is provided with two engagement points, which are spaced one behind the other in the direction of adjustment of the bolt, for the selective engagement of the driving cam of a crank plate, which is located on the inside of an inner lock cylinder fitted on the inside of the door or one in the extension direction of the Riegel's offset rotary handle is attached.
  • the offset attachment of the twist grip compared to the normal backset distance of the outer lock cylinder is advantageous because the twist grip can be kept larger in diameter and is therefore easier to use. If an inner lock cylinder is used instead of the rotary handle, it is arranged coaxially with the outer lock cylinder.
  • the case lock advantageously has a housing, in particular made of die-cast, with an essentially 8-shaped contoured receiving opening therein for the axially offset installation of the inner cylinder or the rotary handle, the circular rotary handle receiving area of which is for one Inner cylinder built-out breakable land is limited.
  • the box lock shown in Figures 1 to 3 in rough outline consists essentially of the lock case 2 to be fastened lying on the door leaf 1 and the lock box 4 to be attached to the fixed frame 3 with a locking bracket 5.
  • the case lock 2 is from the outside of the door over the To actuate the outer lock cylinder 6, which is firmly connected via the fastening screws 7 to the base plate 8 'of the case lock, which is seated on the adaptation pad 8' lying on the inside of the door, which is to be actuated on the inside of the door by the rotary handle 10 mounted on the lock case 9.
  • This twist grip 10 is arranged axially offset with respect to the outer lock cylinder 6 in the direction of the lock bolt 11 to be excluded with one turn, as a result of which the twist grip 10 has a comparatively large diameter without protruding laterally beyond the lock case housing 9 and can therefore be easily adjusted.
  • the tip of the on the twist grip existing arrow shows the retracted or extended position of the bolt 11. If, instead of the rotary handle 10, as in the embodiment of FIGS. 13 and 14 to be described later, an inner lock cylinder is used, this is arranged coaxially with the outer lock cylinder 6.
  • the door bolt 1 can be held in the gap opening position shown in FIG. 3 by means of the lock bolt 11, which can only be adjusted from the outside as well as from the inside, and in connection with the locking bracket 5. However, it can also be held in its fully locked position according to FIG. 2 solely by the locking bracket 5, as long as it is held by a locking slide 13, which is accommodated in the lock case 4 and is provided with an actuating button 12, as described in more detail below, by the lock bolt 11 being extended in one direction Is blocked in the hanging position shown in Fig.1.
  • the locking bracket 5 has the design shown in Figure 4. It has an all-round closed locking slot 14 for the locking bolt 11 cooperating therewith and the locking slide 13 likewise engaging therein, and also a bearing eye 15 designed as an elongated hole, via which it is mounted in the locking box 4 with sufficient movement play or in a pendulum-movable manner.
  • the lock case 4 consists of a die-cast piece which has an upper part 4 ′ which is essentially U-shaped in plan view with bearing bores 16 and 17 located in its U-legs 4 '' and an upper part 4 'on one side to the locking bracket 5 protruding bottom part 4 '''.
  • a plurality of screw fastening holes are provided for the fastening screws 18 and / or the heavy-duty dowel screw 19 which allow the locking box 4 to be attached to the fixed frame 3.
  • these fastening screws 18, 19 are covered or inaccessible in their hanging position by the locking bracket 5 provided on the locking case 4, so that the locking case 4 is only unscrewed when the case lock is open, so retracted lock bolt 11 can be made.
  • the two bearing bores 16 and 17 present in the lock case 4 are of identical nature. They serve to accommodate the folding hinge pin 20 carrying the locking bracket 5 or the locking pin 13 'belonging to the locking slide 13. Both bearing bores 16, 17 are narrowed on the side of the lock case 4 facing away from the locking bracket 5 by a projecting annular shoulder 16 'or 17'. These constrictions serve as abutments for the retaining screw 21 screwed into the hinged hinge pin 20 or for the actuating head screw 12 connected to the locking pin 13 '. As a result, the bearing hinge pin 20 and the locking slide 13 can be modified as required for any right or left use of the lock case 4.
  • the locking slide 13 also has a compression spring 22, which is supported on the one hand on the annular shoulder 17 'and on the other hand on the locking bolt 13' and which therefore endeavors to lock the locking slide 13 with its locking bolt 13 ', which is beveled at the end in the manner of a locking latch, in the position shown in FIG .8 shown engagement position to keep on the locking bracket 5.
  • the locking bracket 5 is held in its depending position shown in FIGS. 1, 2 and 5 by the locking slide 13 and its locking bolt 13 ′ projecting into the locking slot 14 of the locking bracket 5, which is closed all around. If the lock bolt 11 is therefore extended, be it by external or internal actuation of the case lock, the lock bolt head 11 '' provided with upper and lower incisions 11 'according to FIG. 1 engages behind the locking bracket 5 and therefore locks the door properly.
  • This locking state can be clearly recognized on the inside by the fact that the extreme end of the locking head 11 ′′ lies in the recess 23 located between the U-legs 4 ′′ of the lock case 4. In the same single-speed extended position of the lock bolt head 11 '', the door can also be opened securely in columns.
  • the locking bracket 5 can be flipped up by the locking bolt head 11 ′′ which also engages behind the locking slot 14 and can thus be brought securely into the securing gap opening position.
  • the lock case housing 9 is bowl-shaped. It is provided on the inside with guide webs 24 for the lock bolt and its tumbler 25 to be described in more detail below in the direction of adjustment of the lock bolt 11 and also with longitudinal webs 26 and transverse webs 27 located on both sides of the lock device.
  • longitudinal webs 26 two locking openings 28 are provided for a locking cam 29 present on the tumbler 25, while in the cross webs 27 there are screw fastening holes 30 for the attachment of screws connecting the housing 9 to the base plate 8, which via the holes 31 in the lock case front wall are accessible.
  • the housing 9 is provided with a circular indentation or bead 32, in which there are screw fastening holes 33 for the possible attachment of the inner locking cylinder 34 shown in broken lines in FIG.
  • the indentation 32 there is an essentially 8-shaped contoured receiving opening 35 for the axially offset installation of the inner cylinder 34 or the rotary handle 10, the circular receiving area 35 'for the rotary handle being delimited by a bearing web 36 which is simple in the case of the inner cylinder attachment can be broken away.
  • the crank plate 37 shown in dash-dotted lines in FIG.
  • the 10 with the driver cam 38 can be mounted on the inside of the locking cylinder 34 or its core, which can be rotated for key actuation, for example by means of fastening screws inserted into the screw fastening holes 37 'and screwed into the threaded holes 34' indicated by dash-dotted lines.
  • the lock set-up essentially consists only of the lock bolt 11 and the tumbler 25.
  • the lock bolt 11 is formed in two parts. It consists of the locking shaft plate 11 ′′ ′′, which is guided in a longitudinally adjustable manner between the two longitudinal webs 26 of the lock case housing 9, and which is releasably fastened thereon by the screws 39 fastening bolt head 11 '' with the bolt incisions 11 'on top and bottom of it for its locking bracket engagement and engagement.
  • the longitudinally symmetrical design of the lock bolt 11 and the releasable fastening of the bolt head 11 ′′ to the bolt plate 11 ′′ ′′ also ensures a right-left use of the case lock here.
  • the tumbler 25 consists of a fork-like tumbler plate 40, which clasps the bolt shaft plate 11 '''at the rear and is slidably mounted on it via the slot-slot guides at right angles to the lock bolt movement.
  • the tumbler spring 41 is arranged, which is supported on the one hand on the latch plate projection 11 IV and on the other hand on the tumbler plate 40 provided with a corresponding inner recess near the bottom of its locking cam 29.
  • the tumbler plate with its locking cam 29 is locked in one of the two locking openings 28 provided in the longitudinal web 26 of the lock case housing 9, depending on the retracted or extended position of the lock bolt.
  • the box lock On both sides of the fork-like tumbler plate 40, two engagement points 42, 43, one behind the other in the adjustment direction of the bolt 11, are provided for the selective engagement of the driver cam 38 present on the crank plate 37 shown in FIG.
  • the box lock is provided with the rotary handle 10 which is offset in the direction of the lock bolt and on which the crank plate 37 is fastened on the inside by means of the screws 44.
  • the driver cam 38 on it engages in the engagement point 43 of the tumbler plate, whereas the outer locking cylinder engages with its locking thumb in all cases in the engagement point 42 located on the front of the tumbler plate 40.
  • the lock bolt 11, as shown in FIGS. 11 and 12 can be conveniently included or excluded.
  • a shorter locking bar can also be permanently installed on the locking box 4 instead of the locking bracket 5, which at both ends is to be inserted into the two bearing bores 16 and 17 of the locking box - or fastening bolts, which may also be of the type of the bearing bolt 20, is attached. This also allows the door to be properly locked or closed when the secured opening gap is dispensed with, without further changes to the box lock having to be made.
