Definitions

  • the invention relates to a bolt work for a safe door with a base plate on which a plurality of crossbars are mounted in a cross shape, a nut with drive elements engaging in the crossbar rods, a cover plate and at least two locks, the bolts of which engage in the movement sequence of the crossbar rods.
  • Bolt mechanisms of this type have become widely known and are usually equipped with a combination lock and a high-quality tumbler lock with a double-bit key.
  • the locking blocks are connected to additional ropes which are guided via deflection pulleys to an emergency lock, where they are wound onto a rope pulley.
  • At least two base rods have head bolts which are guided in elongated holes in the cover plate, the cover plate having further recesses in the vicinity of the nut, so that the elongated holes together with the further recesses create a rectangular nut bearing flange.
  • the nut bends in such a way that the head bolts are finally blocked when an attempt is made to pull back the basque rods.
  • the bolt heads rest in the locking position over equally large holes in the cover plate. This is followed by free corners of the nut bearing flange, which block the movement of the head bolts and thus of the base rods after deformation by impact on the nut.
  • Fig. 1 denotes the base plate on which the cover plate 2 rests. In between, vertical base bars 3, 4 and horizontal base bars 5, 6, 7, 8 are slidably mounted. In the area where the bars 3, 4, 6, 8 intersect, the nut 9 with the square hole used for actuation can be seen. In the area of the nut 9, 2 elongated holes 2a, 2b are provided in the cover plate, in which the head bolts 10, 11 of the base rods 6, 8 slide.
  • Slits 2c, 2d, 2e, 2f are perpendicular to the elongated holes 2a, 2b and create a rectangular nut bearing flange 2g, indicated by dotting. This area is deliberately weakened by elongated holes, slots and holes so that it deforms when struck on the nut. The corners adjacent to the head bolts 10, 11 then emerge from the plane to such an extent that they abut against the heads of the bolts and thereby block the base rods 6 and 8.
  • a combination lock 12 is arranged in the upper part of the boltwork, and a tumbler lock 13 in the lower part.
  • An electromagnet 14 drives a bolt 15 which, as a third closure, locks the base rods.
  • a profile cylinder lock 16 the beard of which acts on a retraction lever 17, serves as an emergency opening for the closure 14, 15.
  • a distributor for signal lines is indicated, with 19 a microswitch unit and with 20 a structure-borne sound detector.
  • the combination lock 12 is arranged in the main axis of the bolt work.
  • the main axis is the straight line that connects the keyhole, nut hole and thru axis of the combination lock.
  • Fig. 1a the housing of an indirect drive is shown, which makes it possible to accommodate the combination lock outside the hole for the adjustment knob axis.
  • the flat housing 30 three gear wheels 31, 32, 33 of the same size are mounted, of which the first two can be actuated by thru axles. If you insert the plug axis of the adjusting knob into the hole of the gear 31 and couple the gear 32 with the combination lock, each angle of rotation on the adjusting knob is transferred exactly to the lock.
  • Fig. 1b shows how the combination lock 12 and the housing 30 of the indirect drive are attached to the cover plate 2 of the bolt work.
  • the housing 30 is screwed to the cover plate 2 and the combination lock 12 to the housing 30.
  • the bolt 12a of the combination lock is screwed to the tab 21b of the control lever 21 (FIG. 13).
  • the attacker inserts a tool through the opening of the door after removing the adjustment button, it does not come across the combination lock, but into space. If the indirect drive is not used, the bolt 12a is to be connected to the tab 21a.
  • the ceiling 2 shows the perspective view of the bolt work without the locks.
  • the ceiling 2 has rectangular cutouts 2h, 2i, 2k, 2m, into which bent-over tabs of control parts protrude.
  • the lock bolts are attached to these tabs.
  • the recesses 2k, 2m and the keyholes 2n, 2p are created twice because two different backset dimensions are common for the keyhole.
  • the recesses 1h, 1i allow the combination lock 12 to be mounted offset in the main axis of the bolt work or - to make an attack more difficult.
  • 1a, 1b fixed studs are designated on the base plate 1, which receive a lock bridge to be explained later.
  • Fig. 3 shows the side view of the boltwork. On the base plate 1 one can see the base rods 3, 4, 5, 6, 7, the locks 12, 13 with their bolts 12a, 13a and the housing 30.
  • the base plate 1 before the fold shows the shape of the base plate 1 before the fold.
  • the bending lines are indicated with broken lines.
  • the rectangular recesses 1c, 1d, 1e, 1f, 1g, 1h support and guide the basque rods.
  • Sheet-metal tabs 1i, 1k are formed by U-shaped slots, which absorb deformation forces via attached pillars and lock bridges and can lock the entire lever and base cooling system after their deformation. Further deformable sheet metal tabs are designated 1m, 1n. A circular opening for the nut 9 is marked 1p.
  • FIG. 5 shows the folded base plate 1, a control lever 21, a cross lever 22, a keyhole top 23, a deformation locking lever 24 and an angle 25. The interaction of these parts is described with reference to FIGS. 15 and 16.
  • Fig. 6 the cover plate 2 is shown next to the Baskülstangen 3, 4, 5, 6, 8.
  • the nut 9 engages with the fingers in the recesses 3a, 4a, 6a, 8a of the base legs.
  • a locking lever 26, a leg spring 27 and a locking bracket 28 are shown.
  • Fig. 8 shows the boltwork without a lid with the base rods 3-8, the control lever 21, the cross lever 22, the keyhole cover 23 and the deformation locking lever 24.
  • the control lever 21 swivels the parts 22, 23, 24 to the left via bolts.
  • the cross lever 22 moves the angle 25 and tilts the leg spring 27 over the dead center into the other end position.
  • the locking bracket 28 is released via the locking lever 26.
  • the key lock can only be operated when the keyhole is released and the lever 26 is unlocked.
  • the combination lock can only be locked if the key lock has been actuated and the key removed.
  • Fig. 11 shows the four parts of the nut 9. It consists from a disk 9a with two drive fingers 9a1, 9a2 and a square hole 9a3, furthermore a disk 9b with drive fingers 9b1 and 9b2, a ring 9c and a disk 9d with a square hole 9d1.
  • the cross-sectional drawings show that bearing surfaces 9a4 and 9d2 are pressed out of the disks 9a and 9d by partial punchings.
  • the four connecting holes are arranged so that after the riveting the drive fingers have the correct angular spacing and the square holes are aligned.
  • control lever 21 is shown in perspective with the angled tabs 21a, 21b, which are alternatively screwed to the bolt of the combination lock.
  • the mandrel 21c blocks the base 6, the mandrel 21d drives the cross lever 22.
  • projections 21e, 21f are folded, the function of which is clear from FIG. 2.
  • the control lever 21 assumes the lower end position, the locked position.
  • the parts 21e, 21f block the base rods 5 and 7. If an attempt is now made from the outside to force these base rods back, the parts 21e, 21f are bent and moved to the left. They then hit the cutting edges 2q, 2r of the ceiling 2. The control lever 21 is then caught and the entire boltwork is finally blocked.
  • the bolt work described is intended and suitable for use in vault doors of various types and sizes.
