Designation: Arrangement for locking bolt from

Screw cap lids.

The subject of the application are arrangements for laterally displaceable locking bolts for engaging screw-thread container or pipe socket parts inserted in sealing lids Cylinder or mortise locks that can be operated with a removable key or are to be secured.

For screw-thread locking caps with a locking device used for protection, quite complicated coupling devices are usually required between an outer cover part that can be freely rotated when locked and the inner screw-on cover part that can be screwed onto a threaded connector used (DP-4-71 ₅ o67), or also ^ perpendicular to the cover axis laterally outwardly displaceable locking parts (DP-394,469Jfranz.757,683? or for bayonet locking cover USA-2,135,55lj DGM-I, 995,807 / - P 17 5o 888.2- 12).

The object of the invention is to provide a particularly simple arrangement for engagement from the side

sliding locking parts of screw caps to create screw-thread nozzle parts, further required that this screw cap Can only be tightened up to a predetermined tightening torque on the socket thread, so that at any time easy loosening of the screw cap is possible, so there is no mutual thread blockage between the cover and the nozzle

The invention is characterized for this once in that the nozzle with inward above interrupted thread section is provided, against which a key rotation laterally to the longitudinal axis slidable lock bolt engages behind to secure the lid, in which case it is more useful Further training then distributed several times interrupted over the container or pipe socket circumference Threaded sections are provided with wall parts recessed therebetween.

The invention is further characterized by the combination of such a locking bolt arrangement in direct engagement within the connection piece to be closed, with in the screw cap stored standing under compression spring action, resiliently engaging in the upper freely rotatable cover part the lower screw cap part entrained, respectively. then automatically reached for decoupling predetermined cover tightening torque overlaid part »This is achieved that the lower threaded cover part on the interrupted thread sections in the nozzle circumference only up to a predetermined one Tightening torque can be tightened, whereupon laterally displaceable locking parts in this Interstices of the nozzle threaded sections are indentable.

The essence of the invention is described in the figures using exemplary embodiments.

In Figure 1, the upper freely rotatable cover part 1 is shown pulled down with the outside, the lower screw cover part 2 at its flange edge 2 ¹ ends overlapping and I ¹ , with diagonally

Overlying handle part 1 ″ pushed out and in it inserted lock cylinder 3 with below via eccentric 3 ″ in. inclined recess "» 4 'engaging laterally displaceable parts 4 with outside locking part 4 ", as can be seen in Fig. 2 also in plan view. within the lower Schraubdackelteiles 2 one bridge part is of cup-like recessed space 5 above 6 incorporated with a which is supported in the pot bottom 5 ¹ compression spring 7 below. This bridge member 6 engages resiliently in the by e ^ RIQ% <^ ⁱ W ^{<iF u} f '^{t; en} Ra ^ ™ cLes handle part 1 "

Depending on the strength of the internally embedded

Threaded sections 8 'are screwed into the connecting piece 8 from the tabs 6 "in the handle part 1" taken until in response to the thread pressure occurring mutually a predetermined cover tightening torque is reached, whereupon a decoupling

This ensures that a screw cap can only be tightened so tightly that the threads of the screw cap and the socket thread cannot block each other, but on the other hand, to open the closure cap it can be easily moved by hand in the opposite direction of rotation at any time, by now the vertically sloping handle parts 6 ^{MI taken} from the handle part 1 "on the opposite side of the bridge part 6, respectively

unscrew the lower screw cap part 2 from the socket thread parts 8 'as it does AbT). 1 or According to the dimensioning of the force of a compression spring 7, a cover tightening torque which can be determined in advance is to be set so that after reaching a corresponding tightening torque force, the cover does not have to be tightened, since an automatic decoupling between the lower screw cover part 2 and 2 respectively. then again freely rotating upper cover part 1 takes place, so a ratchet-like latching of both parts through the intermediate bridge part 6 with tabs 6 ¹ as a coupling part in cooperation with the compression spring 7 below.

The lock cylinder 3 passed through in the middle engages with eccentric lugs 3 ¹ at the bottom in an inclined guide recess 4 ¹ in a laterally displaceable guided part 4 with an external bolt part 4 ", so that by turning the key 9 this" slide bolt 4 "is inserted inside protruding embossed threaded portion 8 'engages behind within the nozzle part 8, whereby the closure cover is secured against unauthorized opening.

A modified one is shown in Figures 4 and 5 Design 3 form according to the invention shown by two sliding bars on different sides 4 "each engage or lock between two inwardly protruding threaded sections 8 '. This proves to be particularly useful when the play of the threads between the cover and Is great in mutual interlocking, for which then diagonally opposite locking bolts can also be used to around the closure cover to be able to lock with security. In Figures 6 and 7, two are drawn out separately Closing boltf4 "in height depending on the respective The pitch of the cover or socket thread is offset to one another, with these bolts being in grooves
