• a drive gear which is connected in a rotationally rigid manner to the actuating element mounted behind the door and which has an axially displaceably mounted in the door , one-sided toothed locking rod combs, but it is not shown what the locking elements look like that the rod should actuate.
• No. 4,747,628 shows a locking device for a safe (safe), in which a locking rod toothed on both sides is driven from one side by means of a gearwheel which is actuated by a handwheel, while the other toothing drives a plurality of gearwheel-shaped locking elements. Since the gear wheel itself represents the locking element, its diameter must be very large. There is no run-up slope and no tightening movement is provided. The structure of this safe lock is therefore not suitable for cabinets with sealing strips. It is therefore not intended for outdoor use.
• the applicants are also aware of a construction in which a toothed locking rod, which is driven by a gear wheel of an actuating element, drives lever-shaped locking elements which are articulated on the rod and are held pivotably in the door. The disadvantage here is the space required for the lever linkage.

• the toothed locking rod 20 transmits the rotary movement of the drive gear 18 to the gear wheels 26 on the driven side, which are connected to the locking elements 22 in a positive and / or non-positive manner.
• the guide of the toothed rack 24 can be held in an extruded profile 30 by separate guide parts made of metal (eg die-cast zinc) or plastic (injection molded part) or by a shape 35.
• the gear 18 driven by the hand lever 16 can also carry a locking element 22 at the same time, but the spatial separation of the drive and the output gear 26 is simpler, see in FIG. 1 at 41 the end of the drive shaft which lies below the output (opening 45) ,
• Form-fit between the locking element 22 on the one hand and the gearwheel 18 or 26 on the other hand can be achieved, for example, by the gearwheel 26 having bores or depressions 32 into which appropriately arranged projections 34 of the locking element 22 engage.
• the connection of the gearwheel 26 to the driven side of the locking bar 24 for generating the rotary movement on the locking bar 22 thus takes place without further intermediate links and is therefore particularly compact and tamper-proof.
• the locking element 22 can consist of a bent and / or formed sheet metal tab, which can be pivoted in behind a housing or cabinet frame contour 36 by rotation.
• the locking element can also consist of a molded or molded plastic or metal tab 38, as shown in FIG. 3.
• a molded part 40 made of plastic or another material with favorable sliding properties can then be plugged onto such a tab 38, which molded part can then be pivoted in behind a housing or cabinet frame contour, such as the contour 36.
• the metal or plastic profile 30, which also supports the rack 20, can be a be essentially formed sheet metal part with an essentially U-shaped cross section 42, which cross section not only encloses the locking rod but also the gearwheel 18 or the gearwheels 26.
• This U-profile is then expediently closable with an attachable cover 44, so that, for. B. dust tightness is guaranteed.
• Output and drive gears advantageously have the same shape and have, for example, a central square opening 46, which on the one hand enables a rotatable mounting on a round mandrel 48 of the bearing part 28, but on the other hand is also suitable as a receptacle for a square for torsionally rigid connection with a hand lever 16 ,
• the locking latch 22 can also be made entirely of plastic or another suitable material.
• the long-distance run-up curvature of the molded part 40 according to FIG. 1 thus ensures that a large tightening path is realized with relatively low rotational forces, which, for. B. is formed by sealing strips 52, 152 during the closing process, in which the sealing strips are compressed.
