Lock for doors hinged either on the right or on the left

The innovation relates to a mortise lock that can be used for doors hinged either on the right or on the left, in the horizontal center plane of which a latch and a sliding bolt that encompasses fork arms above and below are arranged in one piece and that engages with a bolt tail _t with its two corresponding bolt locks two upper and lower hall? äer central plane symmetrically located locking holes provided locking mechanism is to be operated, while to operate the latch two also symmetrically located above and below the central plane handle nuts are provided, which are drivingly coupled to the latch via pivot levers. Those having: two mirror image provided to the center plane lying closing holes and push nuts mortise can be used by merely turn the door to the right or Linksöffneu, -wozu merely dex pusher with its fittings usually the corresponding conventionally designed iangschild, and optionally the lock cylinder

need to be used or attached. This will be Warehousing and scheduling on site are significantly simplified and corresponding costs are saved. For mortise locks This genus is also essential that through their independent latch and bolt arrangement it is clearly visible from the outside whether the sliding bolt is extended or retracted, otherwise when the door is thrown and at the same time approximately extended bolt corresponding damage to the Lock or strike plate can occur, as with other mortise locks that can be used optionally on the right or left Bit lockable latch bolt can be the case. Another advantage of this generic mortise lock is the short overall height that can be achieved through the respective double arrangement of the locking holes and handle followers.

In a previously known mortise lock of the type mentioned at the beginning, the locking holes are in the vicinity of the central plane and the two handle followers above and below the locking holes, i.e. at a greater distance from the «Ittelebeiie asgsoräset. Ssrch this «Snordsuitg are de ™ SsJjJLqR inevitably given dimensions that are far from the usual and already standardized lock dimensions (DIN 18 250 Part 1, Des. 1976 and DIN 18 251, March 1978) deviate. The deviation of these Kormoafien, namely from the upper edge of the lock faceplate to in the middle of the follower, the faceplate overhang above and below of the lock case, the lock case height, the length of the faceplate and the distance from the middle of the follower to the middle of the scliliex hole

require the use of special accessories for the use of this lock, which in turn has an adverse effect on storage affects.

The innovation is therefore based on the task of creating a mortise lock of the type mentioned above, which while maintaining its simple design is built on the dimensional structure of the aforementioned standard locks and thus the The advantage is that all commercially available, standardized short plates (DIN 18 256 Part 3, March 1978) can be used can and also enables the door manufacturer to use the lock mountings for this lock with the for to manufacture the DIN locks existing cutting and milling tools.

This object is achieved in a generic mortise lock according to the invention in that the two handle followers are arranged between the center plane and the two locking holes and on the sliding bolt tail has two fork legs which the handle followers at least on the adjacent locking holes Ii su = g = si? An <5ts35 ÄsSsnseiten as griffsn snd iiisr wear the bolt locks. Since the respective effective pusher nut with the pusher used is close above the center plane of the lock and the effective free lock hole is below it at a larger standardized distance. _There is the possibility of making the rectangular through holes in the sheet metal and ceiling for the continuous screwing of the standard fitting exactly on the central plane of the lock and thus also exactly at the standard distance below the handle follower that is used in each case.

With a sralil-Hrei.se for doors hinged on the right or left, mortise locks with two each
Closing holes arranged mirror-inverted to the central plane
and jumper nuts it is already known, the latter near the center
located trap and to arrange the two locking holes further out. This mortise lock is alien to the species because it
two separate from each other and at a greater distance from the
Trap has arranged sliding bolts and the handle followers
are also not coupled to the latch via swivel levers.
Rather, it is a disadvantage that both the two handle nuts and the two are arranged separately from one another
Slide bolts with one another via pinions or racks
are coupled, therefore corresponding manufacturing costs
and are prone to wear and tear.

According to another advantageous feature of the innovation
the mortise lock is provided with a reversible slide that can be adjusted vertically and horizontally to a limited extent and is marked with d «; ni

Further features of the innovation are in the subclaims and in the following description of the embodiment shown in the drawing in more detail explained. It shows

Fig. 1 is a plan view of the novel mortise lock with the lock cover removed,

FIG. 2 shows the associated faceplate view and FIG. 3 shows a section along the line III-III of FIG.

The mortise lock shown, which can be used for doors opening to the right or left, is provided with a latch 1 located in its horizontal central plane and a single-piece sliding bolt 2 that encompasses fork-like above and below the latter and which has two handle nuts 3 above and below the central plane , 3 'and locking holes 4,4' are to be actuated, for which purpose, in the installation position shown, the handle is inserted or inserted ^{into the handle follower 3 and the actuating key or a lock cylinder is inserted into the lock hole 4 1.} The locking hole 4 and the handle follower opening 3 ″ are covered by an elongated shield (not shown)

The lock case 5 is connected to the lock cover 6 via the screws 6 ¹ penetrating the interior of the lock case and covered by the faceplate 7 on the front side. In the faceplate 7, as shown in FIG. 2, there is an ent- |
