Locked with a lock that can be moved from the outside

releasable locking bolt.

Patented in the German Empire on June 3, 1920.

According to the Union Treaty of June 2, 1911, priority is due to this application of the registrations in Switzerland of June 17, 1919 and May 5, 1920.

The invention relates to a lock of the type that can also be used without using the ordinary key, which is used to push back the bolt, opened from the outside as may be desirable in many cases. For the stated purpose the locking bolt or the striking plate is in place by means of a switchable locking plate

and held in place and can be exposed by switching off the locking plate.

While in the previous locks of this type, the locking plate in a housing was housed for itself, which entangled the design and arrangement of the whole and makes it expensive, according to the invention, the slide forming the locking plate is on

Locking part (locking bolt, striking plate) arranged itself, creating a considerable Simplification of the whole is achieved.

On the accompanying drawings are several example embodiments of the Subject of the invention illustrated, namely shows:

In the first exemplary embodiment (FIG. 14), it denotes the lock housing which is attached to the movable door leaf 2. In this lock housing, which is provided with a keyhole i ^a , the pawl 3 and the bolt (not shown) are attached in a known manner, the latter being brought into engagement with a locking bolt 4 by means of a key. The closing block 4 is fastened to a plate 5 which is screwed to a second plate 6. On the plate 6, two pins 8 each provided with a notch 7 (Fig. 3) are attached. The latter extend through holes 10 (Fig. 2) of an N-shaped plate 9 into a recess 12 of the door frame 11. The plate 9, which is embedded in the door frame outside the door leaf, is fastened to the latter by means of screws. Parts of a slide 13, which can move up and down in the cavity of the η-shape of the plate 9 and is held in this guide by strips 14 fastened to the plate 9, usually protrude into the notches 7. The slide 13 has at the lower end a part 15 protruding at right angles, on which a central pin 16 is provided. The latter works together with a wedge 17 which forms a whole with a pin 18. The pin 18 is provided with a thread at one end so that an auxiliary key 19 can be attached in the manner shown in Fig. 4 in dash-dotted lines, so that the wedge 17 in its longitudinal direction, i.e. in the direction of the arrows A in Fig 4 can be moved. The operation of the lock described is as follows:

When the slide 13 assumes the position shown in Figs. 3 and 4, parts protrude same in the notches 7 of the pin 8, so that the striker 4 under mediation of acting as a lock slide 13 is firmly connected to the door frame 11 and the door can be locked as soon as the latch is engaged with the striker 4 and the bolt, not shown, is pushed into the striker 4. if now the lock for some reason not with the usual key from can be opened from the outside and the door must nevertheless be opened, so that can be effected by the fact that the wedge 17 (after a key 19 on the pin 18 has been attached) is moved so that the slide 13, the pin 16 with the inclined surface of the wedge 17 cooperates, in the in Fig. 2 in dashed lines Lines indicated location is raised. In this position of the slide 13 is the same with the pin 8 completely out of engagement, so that as a holder for the striker 4 Serving plates 5, 6 and thus also the striker 4 come loose from the door frame and the door can be opened because of the advanced bolt and the latch no longer have any firm resistance.

Instead of the slide 13 by adjusting a wedge 17 by means of a key is brought out of engagement with the pin 8, the slide 13 can also be on electromagnetic Ways out of the notches 7 of the pin 8 are lifted out. One Such an arrangement is shown in Fig. 5, where in the recess 12 of the door frame 11 a

Electromagnet 20 is arranged. If this electromagnet is closed by closing one Excited current, it causes a lifting of the slide 13, so that the latter with the pin 8 is disengaged, whereupon the parts 4, 5, 6 are removed again from the door frame 11 is possible. Since the den Electromagnet 20 exciting current can be switched on at any point and several electromagnets 20 can be connected to the same circuit, so this arrangement is particularly suitable for cases where several doors from one Central office can be opened at the same time, what z. B. in the event of a fire or an alarm and the like in hotels, prisons, poor houses and the like, or on ships.

To when providing a plurality of electromagnets 20 common circuit Each door can also be opened individually without the usual door key In connection with the electromagnet 20 closed another wedge of those shown in Figs Form to be provided. Instead of the lock shown in Fig. 1 can also Another lock of known type with a key displaceable Bolt come to use, and instead of a striker can on the plate 5 also another with an opening for the sliding bolt provided organ, z. B. a strike plate, be attached. In the embodiment according to Figs. 6 to 13 ι is again the lock housing, which is screwed to the door leaf 2 and has a latch 3 on both sides. 4 is attached to the fixed door frame 11 Locking part in the form of a locking plate. Under the cover plate 5 of the lock housing there is a plate 6, on which the two each with a notch 7 (Fig. 13) provided pin 8 are riveted. One pin 8 is closed Door leaf in a hole 10 and the other in a recess 10 'of the slide 13, whereby lock housing and strike plate are locked together. The slide 13, which can slide vertically on the ledge 14, has a transverse pin 16, which with the Wedge 17 cooperates, which is a whole with an angled flat bar 18 forms. 19 is an auxiliary key screwed into the flat bar 18 from the outside.

A swing arm 22 is attached to the shaft 21 carrying the two pawls 3 (Fig. 7, 12), which has a counterweight 23 at the free end, whereby the pawls for usually be kept in their rest position. The arm 22 is here on .dem lower Pin 8 (Fig. 12). By screwing an adjusting screw 24 in the path of the arm 22, the latter can from the room lockable by the door, so z. B. from inside a room, be locked j. This will cause the Latch 3 made impossible. The door can in this way, for. B. locked for the night will.

! To open the lock from the outside with the door locked, pull the auxiliary j key 19 in the direction of the arrow according to Fig. 7 against you, causing a corresponding shift of the flat bar 18 in the strike plate 4 is effected. The one in the strike plate an arm of the flat bar 18 which is pressed by a leaf spring 25 against an intermediate wall is, lifts the Ouerzapfen 16 and thus the lock as a result of the wedge 17 acting slide 12 so far that the j hole 10 and the recess 10 'of the last ■ Ren come out of engagement with the pin 8, which is the attack part of the lock housing represent. As a result, the connection between lock housing and strike plate is canceled so that the door can now be opened.

When the set screw 24 is out of the path of the arm 22 (as in j Fig. 7 drawn), then when the pawls 3 are depressed, the arm 22 is raised swung out. In doing so, it strikes the transverse pin 16 and causes the 3 to be lifted out Slide 13 from the pin 8 so that on this way the door can also be opened.

In order to be able to lock the door from the outside, there is a 6 in the lock housing on the plate a disk 26 (FIGS. 8, 12) is arranged to be rotatable about a screw pin 27. At the disc 26 is hinged to an angle piece 28 suitably made of spring material, which grips around the arm 22, whereby a movement connection between the disc 26 and the arm 22 is established. In the door 2 a sleeve 29 is now inserted (Fig. 6,8), which for receiving a Stud 30 is used. This can be adjusted with an auxiliary key 31. By enough deep screwing of the stud screw 30 can this, with a corresponding position of the disc 26, with a hole 32 of the the latter brought into engagement and thereby the disk 26 in its drawn in Fig. 12 Location to be determined. The arm 22 is now in motion through the disk 26 prevents d. H. secured by the same and thus also the pawls 3. As long as If this security is not removed, the door cannot be opened from the inside. On the other hand, by shifting the flat bar 18 accordingly (pushing up of the slide 13 through the wedge 17)

858754

can be easily opened from the outside, j After the locking washer 26 'has been released by the stud screw 30, the pawls 3 can be moved again. When the released pawls 3 are depressed, the swing arm 22 strikes the transverse pin 16, whereby the slide 13 is brought out of engagement with the pin 8 in each case. In this way, as described, the connection between lock housing and strike plate is canceled so that the door can be opened.

The embodiment of the lock housing shown in Fig. 14 differs from, the ones explained above only by the ones used to lock the swing arm 22! Middle. The locking washer 26 here represents a tumbler which is attached to a web 33 is led. The tumbler 26 has a 'slot 34 for receiving a pin 35, which is carried by the swing arm 22 and this locks when he is with the slot 34 is engaged. Moving the latches 3 is then impossible. The guard locking 26 can from the inside by means of a button 36 both in the operative position and in the ineffective position will be transferred. This can be done from the outside with the help of a key happen, which is to be introduced into the lock housing 1 through a keyhole 37 is.

The modification of the striking plate according to Fig. 15 shows as a peculiarity in place of one Wedge the use of an electromagnet 38 to push up the slide 13. To For this purpose, a rod 39 engages the elongated transverse pin 16, the upper one The end is provided with a nut 40. The same becomes when the circuit is closed of the electromagnet 38 attracted by this, whereby the slide 13 in the ineffective Takes position, d. H. the pin 8 provided on the lock housing releases. Again, this design is suitable especially where a plurality of doors from a central point at the same time should be released, for example in the event of a fire, alarm, etc. in hotels, Prisons, poor houses, on ships, etc.

It should be noted that the present lock is not only on doors, but can also be attached to cupboards, suitcases and similar objects to be locked, the one with the lock open! a fixed second part movable Have part.
