Thüricheriing with chimneys.

Patented in the German Empire on March 19, 1885.

The present invention relates to a security lock for doors and the like is operated from a castle. Essentially, the door security consists of a push rod that is attached to the door with several bolts or pins Securing bars collapse at the same time, and in this way the door in its full extent so solidified that it cannot yield at any point. To move a special mechanism is attached to the push rod in the Thürschlofs.

In the accompanying drawing, FIG. 1 shows the lock with which the push rod moves Mechanism; Fig. 2 is a section according to ι - 2, Fig. Ι; Fig. 3 shows that to the castle, Fig. I, associated security lock for locking the door; Figures 4 and 5 show a half-turn castle, Fig. 6 and 7 the arrangement of the safety bars, which through the push rod can be coupled, respectively on a two-leaf. single-leaf door; Fig. 8 shows the detail of the coupling of push and safety bars.

As can be seen from FIGS. 6 and 7, the door security is effected by a push rod ρ which, in its middle part, where it enters the door lock, is connected to a toothed rack a, FIGS. 1 to 5. By lifting the rack, the locking devices of the door are released, as will be shown later, and by lowering the rack they are coupled, so that in the latter case the door is closed.

The rack α is in engagement with several gears b, the number and arrangement of which can be selected depending on the size of the lock and other considerations; these gears b are moved by a wheel c which can be turned by means of a special key which is inserted into the key tube r. The pins d on a shoulder of the gear c , which fit into corresponding holes in the key, allow the rotation of c, through which the rack α is lifted; a counter spring e on the rack α is compressed at the same time and supports the going down of the rack. The latter happens "by pressing the key firmly into the keyhole, causing the gear c to get out of engagement with the remaining wheels b and the rod α to sink and make the door lock. A spiral spring ^ /" behind the wheel c always seeks engagement from c to restore with b.

This raising and lowering of the rack from the outside by the key can also be done from the inside by the handle g and the button h ; by folding the handle 90 g ⁰ f upward, the spring is also compressed, so the gear c is besides engagement with the rod a, so that these can decrease; the lifting of α is done by turning the rimmed button h, which is firmly connected to one of the wheels b.

These parts just mentioned are on one

Claims (2)

A special lock plate I is mounted, under which there is an ordinary or a security lock of any kind, Fig. 3, and which contains the usual bolts i for locking the door. A pin k can also be attached to this bolt i , which extends through the lock plate I and moves a special bolt m sliding on this, FIG. 1, which serves to completely cover the opening of the keyhole in η; If the bolt i is pushed forward, m is pushed forward at the same time, and in this way some kind of cover can be brought forward in front of the keyhole opening η . In the raised position, the rack α can be fixed by pushing a small bolt ο on the castle, in that this bolt 0 falls into one of the teeth of the rod α or into an incision made especially for this purpose. The spring e of the rack α can also be arranged elsewhere, for example, as FIG. 5 shows, in the rod α itself. The toothed rack α can either be extended upwards and downwards, but it is more expedient to insert two special rods ρ in α , as shown in FIGS. 6 and 7, which cause the closure above the door surface. These rods ρ carry blocks q above, below and at any number of points along their length, which are provided with downwardly directed pins r, FIG. 8. Corresponding holes are drilled in the front of the security bars s that extend across the width of the door , into which the pins r fit. Besides these safety rods s can also corresponding Sicherheitskloben, as Figs. 6 and 7, to install. It is now easy to see that, due to the sinking of the rack α, all fittings, safety rods or clamps are the same be coupled in good time, so that in this case the door is almost in its entire extent is anchored and reinforced, on the other hand all coupled parts by lifting the rack can be solved and thereby the door can be opened. It is of course irrelevant of what external form the parts s and ρ to be coupled are; For example, instead of the pins r on the clamps q, such pins can be attached to the rods s , while the clamps q have the corresponding holes; Other simple coupling devices can also be used without changing the essence of this coupling, which consists in coupling other rods s and clamps with it or by walking up and down a rod α ρ. to uncouple. Pateντ claims: ι. A safety lock for doors and the like, consisting of a rod ap, which can be raised or lowered from the door lock from the outside with a special key, from the inside with handle g and knob h , and which is connected to the armature rods s or Clamp couples or detaches from the same. 2. A Thürschlofs with coupling rod α, which by means of gears can be bc raised and lowered, either g by a special key or handle and knob h, Fig. 1 - 5, and wherein m by a special Hülfsriegel, means i of the main bolt Pin k is moved, the cover of the keyhole for the special key for moving the coupling rod α can be effected, furthermore the coupling rod can be held in place by a small bolt 0 and a spring e can support the downward movement of the coupling rod.
