Definitions

  • the invention relates to a quick release device for a locked door, in particular for an outward opening outer door, the mortise of which engages with a latch and locking bolt in an angled striking plate fastened to the frame.
  • Locked exterior doors have often proven to be an insurmountable obstacle in an emergency, even when the door key was at hand.
  • the invention is therefore based on the object of providing a quick-release device for a locked door which, in an emergency, allows the door to be opened immediately from the inside without the use of a key and without the use of destructive force.
  • the striking plate consists of an inner part opposite the lock face plate fastened in a recess of the frame and a flap part located on the outside of the frame, the latch and locking bolt, and that the inner part and the flap part are releasably connected to one another by a lock that can be lifted from the inside of the frame.
  • the striking plate consists of two parts, namely the inner part fixedly attached to the frame and the outer flap part which is only locked to the inner part but is not otherwise fastened to the frame.
  • This flap part can be unlocked quickly from the inside of the frame according to the basic idea of the invention, so that the door can be pushed open from the inside to the outside without retracting the key of the locking bolt and, of course, also without push-button actuation to retract the latch of the mortise lock, the door Lobe part of the striking plate takes to the outside due to the still existing engagement with the lock.
  • the lock between the inner part and the rag Part of the striking plate can be designed so that the two striking plate parts can be put together again after actuation of the quick-release device, ie they can be locked together.
  • a rotary latch is rotatably and axially immovably mounted on the inner part, which is non-positively connected to an actuating shaft extending to the inside of the frame and, in the locked position, engages in a locking opening or the like of the flap part, from which it engages by rotating the actuating shaft can be disengaged by a small angle of rotation to release the flap part.
  • a particularly simple and compact design of the quick-release device is achieved if the rotary latch is attached directly to the inner end of the actuating shaft, which is rotatably and axially immovably mounted on the inner part, and can be rotated in a plane parallel to the flap part.
  • the actuating shaft simultaneously takes over the mounting of the rotary bolt, for its pivoting or rotating path within the two-part striking plate, because of its rotating plane parallel to the flap part, there is only a small space requirement.
  • a handle is attached to the outer end of the actuating shaft that is guided through the frame.
  • a handle similar to a handle can be done quickly the torque required to unlock the device is transferred to the rotary latch. Since the handle is permanently attached to the actuation shaft, it is immediately available for actuation in an emergency. Since it is located approximately at the level of the door handle, it is also in a position that is convenient for actuation.
  • the handle which has a handle-like shape, is fastened to the actuating shaft in an essentially vertically oriented manner in the locked position. This distinguishes the handle sufficiently from the essentially horizontally oriented door handle.
  • the handle of the quick-release device can of course also be given a shape and color that is very different from the lever handle shape.
  • a particularly simple design of the striking plate inner part is obtained if it is bent from a flat bar in a U-shape and bent at both ends to form mutually aligned fastening flanges which are aligned parallel to the lock faceplate and can be inserted into the frame, and if the inner part of the inner part is bent Bearing block for the actuating shaft and the rotary bolt attached to it is attached.
  • a correspondingly simple design of the flap part is obtained if it is essentially a rectangular, flat and flush plate to be let into the outer surface of the frame, which in the locked position rests against the inner part and on the back is a locking opening opposite the rotary latch defining lead.
  • the arrangement is expediently such that the projection defining the locking opening is bent out approximately U-shaped from a flat bar, which otherwise rests on the tab part in the area of engagement of the latch and the locking bolt, reinforcing the tab part, and is fastened thereon.
  • the flap part is stiffened in the area of engagement with the latch and the locking bolt, so that deflections during normal use, i. H. in the locked position, there is no fear.
  • the arrangement is expediently such that the rotary bolt and the associated locking opening are in their height between the latch and the locking bolt. In this way, a secure central locking of the tab part abutting the inner part is achieved.
  • the flap part is no longer connected to the inner part of the striking plate, so that the flap part can fall down as a throw-off part.
  • the arrangement is preferably such that the flap part is connected to the inner part via a handlebar arrangement, by means of which, when the lock is released, a pivoting displacement of the flap part to the outside is made possible with the release of the latch and the locking bolt.
  • the flap part hinged to the inner part can be moved back into its locking position immediately after actuation of the quick-release device and can be fixed by the rotary latch.
  • the handlebar arrangement expediently consists of two articulated levers which are articulated on the one hand in the vicinity of the fastening flanges on the inner part and on the other hand in each case on an end fold of the flat bar forming the locking opening of the flap part, the articulation points each being formed by vertically arranged pivot bolts, pivoting because of this arrangement the two articulated levers when the lock is released and pressure on the door approximately in parallel horizontal planes,
  • the arrangement can be such that the pivot bolts located on the end folds in the locked position of the striking plate parts lie somewhat further from the flap part than the pivot bolts on the inner part. This arrangement ensures that the unlocked tab part initially moves approximately parallel to the outside, so that it can exit from the inlet opening of the frame, in which it is located in a form-fitting and as seamlessly as possible, before leading away from the latch and the locking bolt of the lock Pivoting begins.
  • the rotary latch can also be designed as a two-armed rotary latch, the arms of which are oriented essentially vertically in the locked position and engage with their ends behind associated projections of the tab part.
  • the rotary latch is very space-saving, so that the striking plate, d. H. the flap part can have a smaller width.
  • the actuating shaft is secured against unintentional rotation by means of a latch that can be released by means of the handle.
  • the cooperating locking elements to be provided for this purpose are to be arranged so that one locking element is located on a part rotating with the actuating shaft and the other locking element is located on a stationary part, the flap part and the elements located on it in this definition in any case in the locked position are stationary parts.
  • the arrangement can be such that, on the one hand, latching elements are attached to the rotary latch and to the associated locking surface (s) of the tab part.
  • FIGS. 8 to 10 and 13 are shown on a larger scale than the other figures.
  • FIGS. 1 to 3 shows a frame 2 installed in masonry 1, in which the outer door 4 shown closed in the direction of arrow 3 is located.
  • a commercially available mortise lock 5 is installed in the door 4, from whose faceplate 6 the latch 7 and the locking bolt 8 in the closed position protrude.
  • the invention can of course also be used in connection with a mortise lock which has several locking bolts or only one lockable latch.
  • the lock is assigned a door handle 9 located on the inside of the door and a door knob 10 on the outside.
  • Door handles 9 and door knob 10 are each attached in long plates 11 or in rosettes.
  • a striking plate designated with the general reference number 12 is accommodated in a recess 13 of the frame 2.
  • the striking plate 12 embodying the invention will now be explained in more detail below.
  • the striking plate 12 consists of an inner part 15 and a tab part 16 which is flush with the outer surface of the frame 2 and which projects over the flap 17 of the door 4. Inner part 15 and flap part 16 are releasably locked together in a manner to be described in more detail.
  • the inner part is bent from a flat bar in a U-shape, as a result of which it delimits an interior 18 on three sides, which accommodates the functional parts of the quick-release device, which will be described later.
  • the inner part 15 is bent into fastening flanges 19, in which there are countersunk bores for receiving screws 20, with which the inner part 15 let into the fold of the frame 2 is fastened to the frame 2.
  • a bearing block 21 located in the interior 18 is rigidly connected to the inner part 15.
  • the actuating shaft 23 extends through a bore 25 made in the frame 2 to the inside of the frame and is rigidly connected at its outer end to a handle-like handle 26.
  • the rotary bolt 24 has a cam-like shape as shown in FIG. 2 and, due to its attachment and mounting, can be rotated in a plane parallel to the flap part 16 by limited angular amounts.
  • the flap part 16 is a right-angled, flat and flush in the outer surface of the frame 2 recessed steel plate, which in the locked position according to FIGS.
  • the rag Part 16 should be embedded in the frame 2 as seamlessly as possible to make it more difficult to attack any burglary tools.
  • it could also be reinforced by a cover made of steel or the like.
  • a flat bar is applied to the front edge 16a of the flap part and is permanently and permanently connected to the flap part 16 at several points 27 (FIG. 3), for example by spot welding or riveting .
  • the flat bar 28 has an approximately U-shaped projection 29 which forms the locking opening 30 (FIG. 3) opposite the rotary latch 24 of the inner part 15.
  • the rotary latch 24 located in the locked position engages in the locking opening 30 and lies against the projection 29 from the inside.
  • the projection 29 can be pressed in somewhat, as shown in FIG. 3.
  • FIGS. 8 to 10 For a more detailed explanation of the link arrangement connecting the flap part 16 to the inner part 15, which is not shown in FIGS. 1 to 7 for reasons of clarity, reference is now made in particular to FIGS. 8 to 10.
  • the flat bar 28 attached to the tab portion 16 has top and bottom end bends 31, the mutual distance of which is slightly less than the distance between the opposite walls of the U-shaped region of the inner part 15, so that the end bends 31 can enter the interior space 18 delimited by the inner part, as a result of which the height position of the flap part 16 is opposite the inner part 15 is additionally secured. Since the handlebar arrangement is designed to match the top and bottom, only the handlebar arrangement shown in FIGS. 8 to 10 will be described in more detail below.
  • An articulated lever 32 is articulated to the end fold 31 by means of a pivot pin 34.
  • Another pivot pin 33 pivotally supports the articulated lever 32 in the vicinity of the mounting flange 19 of the inner part 15. Since the pivot bolts 33 and 34 are arranged vertically, the articulated lever 32 moves in a horizontal direction when the flap part 16 moves relative to the inner part screwed onto the frame 2 Level. As illustrated in FIG. 8, when the striking plate 12 is locked, the pivot pin 34 is a little further away from the tab part 16 than the pivot pin 33. Because of this articulation situation, when the articulated lever 32 is pivoted out, the pivot pin 34 moves on the one shown in FIG. 8 and provided with a directional arrow Circular arc 35.
  • Fig. 9 shows, like Fig. 7, that at the end of the pivoting movement, the flap part 16 is pivoted so far to the left that any engagement with the latch 7 and the pre-closed Lock bolt 8 of the mortise lock 5 is canceled.
  • FIGS. 1 to 3 and 5 To explain the function of the quick release device described so far, reference is now made to FIGS. 1 to 3 and 5.
  • the handle 26 is in the locked position of the striking plate 12 in a vertical position, from which it can be swiveled out to the right and to the left in the embodiment shown and described.
  • the rotary bolt 24 emerges from the locking opening 30 formed by the projection 29, as a result of which the locking is released.
  • This situation is shown in Fig. 5 using the example of a pivoting of the handle to the left (based on the drawing).
  • the rotary latch 24 'fastened to the actuating shaft 23' is designed with two arms. His arms 37 and 38 are in the ver locked position aligned vertically and engage with their ends behind on the tab portion 16 'projections 39 and 40.
  • the function of the quick release device equipped in this way corresponds to that described above. 11, the unlocked position of the rotary bolt 24 'is again indicated by dash-dotted lines.
  • latching elements can be provided, for example in the arrangement shown in FIG. 13.
  • a recess 41 is made in the surface of the arm 37 of the rotary latch 24 ′ facing the projection 39, into which a rib 42 or the like attached to the opposite surface of the projection 39 is engaged.
  • Corresponding locking elements 41, 42 can of course also be arranged on the rotary latch 24 or on the projection 29 in the exemplary embodiment described with reference to FIGS. 1 to 7.
