Locking device for sash locks, rod locks and the like.

• The invention relates to a locking device for sash, Rod locks or similar locks that can be actuated by means of a double-bit key, multi-point mandrel key or the like.

In particular in electrical switchgear cabinets, rod locks or cam locks are used to lock the doors, which are actuated by means of double-bit keys or also polygon keys, in particular square keys. In many applications, such as crane systems, excavator equipment, etc., the control cabinet doors and their locks are subject to strong shaking and vibration effects, which, if the locks are unsecured, lead to an unwanted and often dangerous opening of the control cabinet door. Another problem arises when a key catcher is used for the lock, which is used to prevent or at least make more difficult the opening of such doors by unauthorized persons with the aid of keys and tools that are not intended to open the door. The key catch has a cross-section of the key _<matched breakthrough and made difficult by the insertion of keys or tools with other profile shape or even makes this impossible.

POSTSCHECKiBtRLiNWEtT (BLZ 100 100 10) 1327 36-109 ■ German ανκ (BLZ 300 700 10) 6 160253

For the cell or cabinet doors of electrical switchgear, for example, double-bit keys are specific according to DIN Dimensions provided, the two opposing key bits as well as an axial bore of standardized dimensions in each case. These double-bit keys also include a Keyhole standardized in terms of its dimensions, which is formed, for example, by the key catch.

With closures of this type occurs when vibrating the problem that the actuating shaft of the closure, which is on her End has corresponding depressions to be detected by the key bits, due to caused by the shaking Displacements not ^ exactly in the included or excluded Position stands, d. This means that these depressions are not exactly aligned with the openings in the keyhole. In this case it is not possible to insert the double-bit key. It has to be done in a cumbersome way with auxiliary tools be achieved that the depressions are again precisely aligned with the openings of the keyhole before the Double-bit key (or polygon key or the like) can be inserted.

Such unwanted shifts can also occur due to vibrations that z. B. by the inside of the control cabinets arranged devices arise, or by the transport of the cabinets, z. B. when transporting control cabinets from the factory to the installation site on trucks. At the installation site, the locks have then often shifted a little and the locks can no longer or no longer be opened easily with the keys provided for them, what is very annoying to the user.

In the case of sash locks one has so far helped each other by the fact that at the end connected to the axis of rotation of the sash in the circumference of which two or three incisions were made, creating a kind of cam track which a spring-loaded cam could slide. The locking

1 30039/0629

places were the points at which the cam went into the depressions penetrated. However, this type of locking is not particularly secure, because the cam out of the way due to greater rotational forces Lock can slip out easily. Another disadvantage is the unavoidable manufacturing tolerances, which can also lead to the fact that the locking points are not precisely fixed. Another common backup is through a Achieved additional lock, which, however, is expensive and requires both hands to operate.

The object of the invention is to create a locking device of the type mentioned at the beginning, which does not come free even with a strong torque acting on the closure manufacturing tolerances do not lead to inaccuracies in the locking fixation and no further hand for unlocking requires.

This object is achieved in that the actuating shaft of the lock is axially inwardly displaceable against spring force is mounted and at the front end has at least one nose projecting radially beyond the shaft diameter, and that the bearing housing for the actuating shaft has a sliding surface for the nose with at least one adapted to the nose dimensions Has incision for its locking recording.

Characterized in that for unlocking the locking device a Movement must be carried out that is not the closing or opening movement, eliminates the possibility that by a strong torque load on the lock, the lock is released. In addition, since no cam track is required, the must always have certain roundings, there are also no inaccuracies with regard to the exact locking point, as z. B. can hardly be avoided by manufacturing tolerances.

Instead of providing the nose on the actuating shaft and the incision on the bearing housing, one could of course also vice versa the actuating shaft with the notch and the bearing housing

130039/0529

furnish with the nose.

It is particularly favorable if the sliding surface of the housing (or the actuating shaft) has two incisions, each offset by 180 ° or four by 90 ° to each other, and there are also two or four associated lugs, because then there is a particularly stable locking system and a total of two or four locking positions offset from one another by 180 ° or 90 °. The former arrangement is favorable, if the key z. B. should only be removable in the closed position, while in the second arrangement with four incisions the key z. B. can be removed in both the open and closed position. Are more locking positions required or if the locking positions are to be in different angular relationships to one another, they are correspondingly more or differently arranged Provide nose and incisions.

The arrangement of four, each 90 ° offset from one another Notches or noses is also advantageous because it allows the lock to be both left and right can also be used as a right-hand lock. There is therefore no need for different doors to close on the left or right Closures in stock. To be kept.

In order to achieve the greatest possible strength, what to strive for small design is of considerable importance, it is advantageous if the noses or the incisions each over about 90 ° or 45 extend (with two or four noses with a distance of 180 ° or 90 °).

In order to achieve the axial displaceability of the actuating shaft with respect to the lock or key catch, there are various possibilities. On the one hand, the closure itself could be designed in such a way that its actuation axis is subject to displacement against spring force. If this is not the case, according to a development of the present invention, the actuating shaft consist of an inner and an outer section,

130039/0 529

wherein the inner section at its outer end has an axial, prismatic (i.e. not circular) depression, such as a square blind hole, into which the correspondingly contoured subsequent End of the outer portion is axially slidably received.

In order to generate the spring force against which must be pressed when pressing in the key, could according to another embodiment the invention around the actuating shaft around a compression coil spring are arranged, which on the one hand an annular shoulder arranged at the outer end of the actuating shaft and, on the other hand, on one formed by the shaft bearing Support ring shoulder.

In the case of a sash lock, in which despite the additional Displaceability is to be maintained as short an overall length as possible, it is advantageous if the shaft bearing is at the front end from the front-end housing, at the rear end of a quarter-turn axle rotatably mounted in the front-end housing (e.g. the shaft section) is formed. The sash axle (the inner shaft section) itself could be from one at the end or inside the inner the end of the Vorreiberehäuses attached ring part are held against axial displacement, this ring part for example is held in place by means of indentations inside the liner housing. This construction enables the internal construction push it from behind into the liner housing and then determine the arrangement by means of the ring part.

The construction of the rod lock can be a bit simpler be held because there is more space available and locking device and lock not from the outset than an overall arrangement needs to be available. Rather, the The locking device is only attached to the rod lock during assembly of the rod lock.

130039/0529

3010Ή5

In order to secure the locking device and the downstream lock against the effects of soiling, 'it is advantageous to if the shaft or the bearing have an annular groove in front of the lugs to accommodate an O-seal.

With the construction according to the invention there is an exact locking of the closure in z. B. the closed position, in which the key can be withdrawn, or also in the open position, if also in this open position Closure must be removable, which is especially true for sash locks, which usually consist of several closures per Door that can be operated with only one key.

In the case of rod locks in which there is only one lock per door, however, it can be sufficient or even expedient when the key can only be removed when the door is closed. In this case it is sufficient if only the closed position can be locked.

In the case of the locking device for a sash, it can also be advantageous to use the one formed by the ring part To provide sealing plugs with two ears, which in cooperation with a projection protruding from the sash Form rotation protection so that the sash fastener only moves the desired 90 ° from the open to the closed position, for example can be pivoted and vice versa.

The invention is explained in more detail below on the basis of exemplary embodiments which are shown in the drawings.

In Fig. 1 a rod lock is shown, which in its general form has long been known, see for example the Fig. 2 of DE-Gbm 76 21 270. The rod lock shown in Fig. 1 consists of a lock part 10 on which a Bracket or lining 12 is attached by means of welding or screwing 14. The lining 12 is with the door leaf 16 welded or, as shown, by a nut

130039/0529

attached, which is also used to attach the locking device 24, which has a key catch 22 and a tubular housing 20 serves. Through the lining 12, the lock part 10 holds a certain distance from the door leaf 16, so that for the locking device 24 sufficient space is available without the key catch 24 too far above the plane of the door leaf 16 protrudes.

On the lock part 10 two round rods 28 are attached, which extend to the upper or lower end of the door leaf 16 and there, when the door is closed, come into engagement with a nose or a web of the door housing (not shown).

In order to be able to open and close the rod lock a square hole 34 is provided so that a locking bolt out of the lock part 10 by means of a square mandrel 26 and can be moved in and also the round rods 28 can be moved in the axial direction. For operating the square mandrel 26 is a locking device according to the invention having arrangement, which consists of the aforementioned cylindrical housing 20, which is of a key catch goes out, wherein the housing 20 carries a thread on its outside to the housing by means of a nut 18 within a To be able to set breakthrough in the door leaf 16. As shown in FIG. 7, the housing has on one side a flat 30, which with a corresponding chord-like projection of the punched hole in the door leaf 16 cooperates in such a way that a rotation lock results. It is also possible to have two opposing or four such types, each at a distance of 90 from one another Flats are provided if the housing is in z. B. two or four differently rotated positions can be mounted should be. Fig. 6 shows an embodiment with four such flat areas 30.

Inside the housing 20 of the locking device 24 is the actuating shaft 32 is arranged, which is shown in Figs. 8 to 10 in greater detail. The operating shaft

130039/0529

has the aforementioned square drive at its rear end 26, which cannot rotate but slide in a corresponding square recess of a lock nut 36 of the locking part is guided, which lock nut 36 moves the round rods 28 on rotation via articulated connections not shown in detail and also carries a locking tongue which, during the locking rotation of the lock nut 36 from the housing of the lock part comes out and locks the door in the middle area. The lock nut 36 has a cylindrical bore behind the recess 34 38, which has a diameter such that a coil compression spring 40 can be received. The compression spring 40 is supported on one side on a shoulder 42, which is formed by the lock nut 36, while on the other Side lies against a slightly recessed annular shoulder 44, which is formed by a projection 46, which according to FIG. 10 still has a total of four projecting noses 48. These lugs have such radial and tangential dimensions that they fit into corresponding notches 50 which extend from a sliding surface 52 which is inside the bearing housing 20 to sliding receptacle 5 of the lugs 48 provided in the unlocked state is. The central portion of the actuating shaft, numeral 54, has a circular diameter so formed is that the compression coil spring 40 can be pushed over it with little play.

The outer end of the actuating shaft 32 is a round head 56 which is rotatable within a corresponding bore 58 of the housing 20 is stored. The end face 60 of the round head 56 has one or more depressions 62 which are adapted to the shape of the to be used key are adapted and in the present case can accommodate a double-bit key with his End is shown in Figs. In particular, those are required for the double-bit ends 64 of the double-bit key Radial incisions 66 and the annular incision are provided, which has a spike-like projection 68 in the middle results, which penetrates into a corresponding depression 72 of the double-bit key and leads this and also the Einstek-

130039/0529

ken other actuating devices difficult.

The key catch 22, which is shown in FIG. 4 in FIG a plan view is shown.

The depressions 50 and the noses 48 are with respect to the arrangement of the opening 64 in the key catch 22 and the position of the Radial incisions 66 in the head 56 of the shaft 32 arranged so that the lugs 48 due to the compressive force of the spring 40 in the The incisions 50 of the sliding surface 52 of the housing 20 snap into place as soon as the radial incisions 66 become the corresponding incisions 76 of the opening 74 in the key catch 22 exactly align, provided that the lock is in the closed position. This means that the double-bit key (or any other key for which the lock may be intended), after can be pulled out of the key catch 22 after locking. The lock prevents, for example, by If the actuating shaft 32 is shaken when the key is removed, it is only twisted slightly, so that it is ensured that later the double-bit key pushed through the key catch 22 again and inserted into the depressions 62 unhindered can be when the shutter is to be opened again. To open, the double-bit key is turned 90 °, in which position the radial incisions 66 of the shaft head are no longer below the radial incisions 76 of the key catch 22 so that the key cannot be removed in this position. However, the key should also be in the open Position of the rod lock can be removed, only two further radial incisions 76 need to be provided, which are offset by 90 ° with respect to the incisions 76 shown in FIG. 4, see, for example, that in FIG. 14 Another embodiment shown with its incisions 176.

In order to close or open during the necessary Rotation process to unlock the lock, which is formed by the lugs and the incisions 50, must after insertion

130039/0529

of the double-bit key these are pressed against the force of the spring 40 by such an amount that the lugs 48 off the notches 50 slide out and thereby come to rest on the sliding surface 52 with a slight rotation. In this position the shaft 30 can be rotated by 90 °, for example, to lock or unlock the lock.

The depth of the depressions 62, dimension A, and the height of the double bit 64, dimension B, and the depth of the depressions 50, Dimension C, coordinate so that the bits 64 of the double-bit key only then have wandered through the opening 74 of the key catch and below the inner surface 78 with her Rear edge 80 come to rest as soon as the noses 46 have also come out of the incisions 50. That means that Dimension B, the bit height of the double-bit key, which is 7 mm according to the standard, roughly the same as that required for unlocking Stroke when inserting (for example 3 mm) plus the insertion path should be in the head of the shaft 32 (e.g. 4 ... 4.5 mm).

In FIG. 9, an annular groove 82 can also be seen in the shaft 32, in which an O-ring seal 84 can be inserted, which forms a seal with the wall of the bore 58, which at If the key is not inserted, it shields all mechanical parts of the lock from dust and moisture. Instead of To provide an annular groove 82 in the shaft 32, a corresponding annular groove can also be provided in the housing 20, although strength problems may arise there.

Reference is now made to the further embodiment shown in FIGS which represents a sash lock, which is generally provided with the reference number 110. The closure comprises a tubular housing 120 which, similar to the embodiment shown in FIG. 5, has a sliding surface 52 is provided, which has incisions 50. The tubular housing, however, has a greater overall length and has on his inner end a projection 111 pointing in the axial direction,

130039/0529

the one carried by the sash tongue 113 as a stop Nose 115 could serve to rotate the sash lock to be limited to essentially 90 °.

The tubular housing 120 in turn has the already with respect to the in FIGS. 1 to 10 illustrated embodiment described Chamfers 30 for the purpose of rotation lock, the tubular housing is also fastened again by means of an on top of the Outer surface of the tubular housing 120 arranged thread can be screwed Nut 18. The key catch of the tubular housing also corresponds to that of the housing 20, with the difference, however, that a total of four radial incisions 176 are provided, each 90 spaced from one another. The double-bit key can thus both in the locked position and in the open position can be withdrawn from the lock, which is at Quarter-turn locks are favorable because there are often several (for example three) quarter-turn locks on a control cabinet door are arranged, which should expediently all be able to be opened and closed with just one cam key. While To open it, the fastener must be the first to open the lock be removable in order to open the second or third lock without the need for a second or third key Should be available.

It is also important for a fastener that it can be used both "right" and "left"; i.e. that the construction should be made so that it can be used for both left and right hinged doors. in the the following shows how this is achieved.

As can be seen from Fig. 11, but in particular from Figs. 18 to 21, is in the present case to achieve an axial displaceability of the actuating shaft with respect to the sliding surface 52 with incisions 50 existing front locking part, the actuating shaft 132 is made "in two parts". Man However, the construction can also be seen in such a way that the outer part shown in Fig. represents the actuating shaft 132,

130039/0529

while the inner part shown in Fig. 21 to the sash belongs and is comparable to the lock socket 36 of the rod lock shown in FIG. The lower part therefore has given the reference numeral 136.

The part 132 corresponds essentially to the part 32 already described in FIG. 9, with only the middle part 54 the actuating shaft 32 shown in Fig. 9 is significantly shorter because the overall length available here is smaller have to be. The actuating square 26 of the part 132 engages in a corresponding square opening 134 of the part 136, so that again a torsionally rigid, but axially displaceable connection between the parts 132 and 136 results. The locking spring 40, which is also present here, is received by part 136 in a corresponding annular groove 142. The part 136 has at its lower end a shoulder surface 143 with which it - possibly with the interposition of a spring washer 112, see 25 and 26 - is supported on a retaining ring 114, which after the introduction of the front part 132, the spring 40 and the rear part 136 and possibly the spring ring 112 in the end of the tubular housing 120 is inserted and fixed there in a suitable manner, for example by means of a ring indentation 145. The holder 114 at the same time also forms the axis of rotation for the shaft part 136 by reducing its diameter End 145 in the bore 147 of the bracket 114 to fit comes. Behind the bearing section 145 is a prismatic part 147, in particular a square, to which the Quarter-turn tongue 113 with a correspondingly shaped opening attached and then fixed by means of a head screw 151 can be. The screw 151 can be screwed into a threaded hole 153 which is arranged axially in the part 136.

The assembly end of the sash tongue provided with the opening 149 113 slides on the retaining ring 114 or the end of the housing 120 and thus represents an axial locking for the part, which on the other hand is provided by the shoulder surface 143.

130039/0529

10115

In the embodiment shown, the retaining ring 114 has in addition to an annular groove 155, which is used for fixing by means of an impression 145, two ears 157 and an incision 159 on. The ears 157 are arranged in such a way that their surfaces 161 adjoin the surfaces 163 of the projection 111 of the housing 120 and after inserting the retaining ring 114 into the end of the housing 120 secure it against rotation, on the other hand, the ears form stop surfaces with their other surface 165 for the nose 115 of the sash tongue 113. The projection 111 of the housing 120 is not used here directly, but only via the retaining ring 114 as a stop for the sash tongue 113, although a construction would of course also be possible which abuts the nose 115 directly on projections that are formed by the housing 120.

Instead of the retaining ring 114 by means of the indentation 145 in the housing 120, other types of fastening are of course also conceivable, such as fastening by means of a spring clip, pinning or bonding.

Here, too, a sealing ring 84 is again provided, which is arranged in an annular groove 82 arranged in part 132 can.

The sash lock 110 is in its manufacture in Assembled way that in the manner already described, the inner parts of the housing 120 plugged together and then the Retaining ring 114 is arranged and fixed, whereupon the sash tongue 113 protrudes from the housing 120 Square 147 attached and then the screw 151 in the threaded hole 153 screwed in and - if necessary with a washer 167 in between - screwed tight.

The thread provided for the nut 18 on the outer surface of the housing 120 does not extend all the way to the rear end of the housing, but only up to a point which is designated by 169 in FIG. The remaining housing length D is slightly larger

130039/0529

than the width of the nut 18 so that this is still on the end of the housing 120 is released and pulled off via the sash tongue 113 can be. The tongue 113 does not need to be unscrewed in order to assemble the sash, rather one will after removing the nut 18, insert the fastener through the corresponding one Put the punched hole through the door leaf - this is easily possible through the curvature 171 of the tongue 113 - and then guide the nut 18 over the tongue 113 and then screw it onto the housing 120.

It has already been mentioned that by providing four radial incisions 176 offset from one another by 90, and also by the fact that that four bevels 30 offset from one another by 90 ° are present, the lock as a left lock as well as Right lock can serve.

Regarding the operation of the cam lock as well with regard to the lifting height and the height of the beard projections 64 the same conditions apply as already described with regard to the rod lock.

It should be mentioned that, despite the additional safety device, the overall length of the housing of the sash lock shown here For example, it is only 6 mm larger than is the case for sash fasteners using this additional safety device not own. This additional housing length can easily be achieved by appropriately dimensioning the sash tongue 113 are compensated, which anyway in different Dimensions for the different cabinet door constructions are available.

The illustrated embodiments relate to double-bit keys, however, the invention can just as well be applied to differently shaped keys and associated locks, insofar as it is there on an exact alignment of the actuating shaft with respect to a key catch in the closed and / or open state of the lock arrives and / or the lock against un-

130039/0529

Intentional or incorrect opening of the door due to vibrations should be secured without the possibility of one-handed operation get lost.
