Abstract

The bar lock for mounting in one or two rectangular perforations (32, 34), preferably in the tilting space of sheet-metal cabinet doors, has a lock (16) with a follower (64) which carries a pinion (62) and is held rotatably in a follower and rod bearing (60) and which is rotatable by means of an actuating device, such as a handle, pivoting lever, socket wrench or the like, guided outwards through the door leaf (12). It also has at least one rod (18) which extends parallel to the door edge, if appropriate in the tilting space (10), possesses a toothing or perforation (66) for the engagement of the pinion (62) in the region of the lock (16) and is mounted displaceably in this region and at at least one point outside the lock (16) in the door leaf (12). Locking devices are attached to the door frame and to the rod (18) and come into engagement with one another during the displacement of the rod (18). According to the invention, the rod (or rods) (18) and the follower and rod bearing (60) guiding these rods (18) in the region of the lock (16) are respectively made symmetrical or double-symmetrical in such a way that, without the removal of the pinion (62), the bar lock can be used both for doors opening to the right and for those opening to the left, with any selectable opening direction of rotation of the lock-actuating device, simply by reversing or interchanging the rod or rods (18) and/or reversing the lock (16). <IMAGE>

Description

The invention relates to a rod lock for sheet metal cabinet doors according to the preamble of claim 1.

Such a rod lock can be found in DE-OS-34 07 700. This rod lock has compared to others Constructions such as those from German Utility model 85 05 588 or from European Patent specification 00 54 225 are known, the advantage that with band-shaped push rods is worked so that the total width of the rod lock remains considerably narrower than in the earlier constructions and therefore possibly also in the relatively narrow canting space of sheet metal cabinet doors Can be accommodated, this type of accommodation the has the particular advantage that on the one hand the inner light Volume of a control cabinet for other components, in particular Switching devices, fully available, on the other hand otherwise dead space is exploited, and finally, which is of particular importance, the rod lock is located outside the area of the cabinet to be sealed, so that the rod closure of the aforementioned Kind of any sealing devices are dispensable.

A disadvantage of the known rod lock is that by special design of the middle part (Fig. 8 document) or the ends of the push rod (Fig. 7) (Arrangement of teeth on the narrow sides of the push rods) these push rods for both left and for cabinet doors hinged on the right can be used, however, if the teeth are not up to Rod end is continued, or other obstacles Slip through, not easy pre-assembled lock to be changed, rather must with removal of a cap 38 (Fig. 3) and one Circlip (in ring groove 32) before the pinion in cumbersome Way disassembled from the castle. Only the rods can be taken out in the desired way changed, reinserted and the pinion mounted again will. This is especially true if there is a continuous Push rod that is not used in the Guide channel of a pre-assembled lock case inserted can be, but also when the bar is not continuous, at the end of the push rod is toothed and therefore in itself from above or from below into the lock case can be inserted, this insertion can still be done in succession other management facilities only after dismantling others Components may be possible. If the arranged on the rod Locking devices through cuts in the rod It will also be difficult to form the poles both to use on the left as well as on the right, or the actuating device to change because the then necessary bilateral Cuts cause the rod to be excessively weakened can. Another disadvantage is the fact that when State of the art, the pinion is only supported on one side, what the load on the bearing material and the pinion material increased and u. U. the use of simple plastic materials excludes for this component.

From DE-A-2 033 042 is known per se, in a transmission for one Espagnolette fitting to form the gearbox housing from two identical parts and to store the drive pinion in the gear housing. The gear housing forms also guide slots for a drive rod. Two connecting rods cannot are driven, and the housing is also unrelated to a key catch or key tag.

From DE-A-3 300 423 an edge gear unit is known in which for storage of a pinion, two parts of essentially identical construction are used, wherein the two parts each have a bearing base in which the pinion is supported at both ends. The problem of changing from right to left is not addressed here, however, no choice of the direction of opening and closing during assembly, let alone at a later date.

DE-GM 74 03 366 is a drive housing for a locking device known for windows, doors or the like, in which profile sections as the starting material suitable length, into the recesses for a pinion and in individual production Through and threaded holes for bolts are made. Convertibility from right to left is not addressed and because of asymmetry the housing halves are also not given, just as can not in a simple manner Direction of opening and closing can be selected or changed.

The object of the invention is to provide a rod lock for sheet metal cabinet doors develop the preamble of claim 1 such that it continues to the right and can be used on the left and also the closing and opening direction of the Lock remains freely definable, but at the same time a subsequent change without cumbersome disassembly work, while the construction of the Drive the push rod should be modified so that its individual Components can also be made from simple plastic materials on request can without stability problems.

Furthermore, the drive should act as axially as possible on the flat bar, to prevent unwanted canting that increases friction. At the booth In technology, such canting phenomena cannot always be prevented because there the drive engages on one side on the flat bar.

Finally, in addition to simplifying the assembly and convertibility of the Closure can also be achieved to simplify the bearing bracket.

The stated task is solved by

• that the base part carries a shoulder which lies in the area of the opening on the outer door surface,
• that a base protrudes through the opening,
• that the pinion is mounted on one side in the cap part and on the other side in the base part,
• that a common centering plug connection is formed on the cap part and base part, for which purpose the base is formed on the shoulder of the base part as a centering base and is inserted into the cap part,
• that the cap part lies with its end face facing the base part in the area of the opening on the inner door surface,
• that the cap part is attached to the base part with screws,
• that two parallel longer side walls and two perpendicular shorter side walls extend from the cap bottom and form the guide slots for the rod (s), and
• that the toothing is designed in the form of a single perforation running along the longitudinal axis,
• or alternatively,
• that the base part carries a shoulder which lies in the area of the opening on the outer door surface,
• that a base protrudes through the opening,
• that the base part is formed in two parts and from a key catch part with the shoulder and from a bearing part which, together with the cap part, forms the guide slots for the rod (s),
• that the pinion is mounted on one side in the cap part and on the other side in the bearing part,
• that a common centering plug connection is formed on the cap part and bearing part,
• that the bearing part rests with an end face facing the key catch part of the base part in the area of the opening on the inner door surface,
• that the cap part and the attached bearing part are fastened together by means of both penetrating screws to the key catch part of the base part,
• that from the bottom of the cap part and, in mirror image, from a bottom of the bearing part two parallel longer and two perpendicular perpendicular shorter side walls and in the assembled state together with the bottoms form the two optionally assignable guide slots for the rod (s), and
• that the toothing is in the form of a single perforation running along the longitudinal axis.

This combination of features enables the solution of the task above. In particular, it is possible through The cap part can be removed without additional removal a pinion lock, such as a circlip, the Pinion together with one or two push rods take out the rod lock and for example by moving the push rods or by exchanging one Push rod the rod lock to a new task adapt. The construction also allows that Use of plastics for the individual parts of the drive, which simplifies manufacture and noise reduced when the lock is pressed. The construction also allows the pinion to engage in the center Push rods and in this way prevents tilting and thus possibly increased friction and correspondingly increased Power requirement. The construction is also from Advantage as they adapt easily to a locking system lets that the replacement of various handles, locking devices and should enable the like. Of the Rod closure according to the invention is therefore more versatile usable as is the case with the prior art.

Despite the versatility, the closure is made only from a few individual parts, which in addition to the cheapening of the Manufacturing and simplifying assembly and conversion also to simplify warehousing is coming.

It is favorable if the cap part in the cap bottom central opening for the nut storage and one top and one each located below the central opening, inside the cap protruding eyes, each with a countersunk hole Includes a mounting screw. In this way can the cap part for the purpose of replacing for example the rods, but also to change the type dismantle the actuator easily. Does that exist Drive / pinion and rod bearing from a base part and a cap part of essentially identical construction, there are further manufacturing simplifications and thus Cost savings. Assembly simplifications result if through measures described in further subclaims Base part and cap part have mutual guides. By projecting over the base part and over the end face Projections can also be arranged a leaf spring, who attaches to the circumference of the nut and this against unwanted Secures rotation, especially if the nut circumference in Distance of 90 ° flats to accommodate the leaf spring in has the rest positions of the closure.

Due to the special construction of the invention The lock can be the base of both a swivel lever lock be part of a hand lever lock, a double-bit lock or another one Closure. There may only be a single part of the entire closure, which in turn too leads to significant cost savings, both in terms of Manufacturing as well as in terms of storage and Assembly.

According to yet another development of the invention, the especially the tilt-free transmission of the driving forces serves from the pinion to the rods, is the flat profile having rod of the rod lock axially symmetrical with respect to the longitudinal axis and with respect to a transverse axis, the halved the perforated or toothed area of the rod.

The invention is described below using exemplary embodiments explained in more detail, which are shown in the drawings are.

Fig. 31 in three views yet another rod lock.

Fig. 1 shows a view of the canting space 10 a sheet metal cabinet door 12 one in rod lock arranged in this room 14, consisting of a lock 16, one of which rod 18 running in the canting space 10 going out, for one, inside the castle 16, but also on the door leaf 12 in a rod bearing 20 is slidably mounted. The sheet metal door 12 is via hinge straps 22, see Fig. 2, hinged to the cabinet body 24, which in turn the other tilting room 11 take advantage of one between the outside Take advantage of tilting space 11 by one between the outer bend 26 and one welded on the inside of the door leaf, one Seal 28 receiving profile sheet 30 is formed is. It is common in metal cabinets that have such tilting spaces 10, 11 in the canting space for the lock rectangular opening 32 or 34 arranged, with planned use of retractable Swivel lever locks are two symmetrical arranged to the horizontal door center 36 Rectangular openings 32 and 34.

As in Fig. 3, an axial sectional view along line B-B of FIG. 1, is a hook-like projection on the cabinet body 24 38 screwed into the when closing the rod lock one of the lock rod 18 carried double roller pin 40 penetrates and so forms a lock 42.

One possibility for rod guidance is in Section D-D reproduced which rod guide 20 in the corner space of the folding channel 10 arranged and designed so that the ribbon bar 18 inserted into the guide can be. The guide 20 can, however also on the other side of the rod 18, so outside of sometimes for welding work corner area of the door leaf that is difficult to access to be appropriate.

From Fig. 3 it also appears that the Lock 32 a lock nut, pinion and rod bearing 60 includes one carrying a pinion 62 Lock nut 64 holds rotatable. The lock nut is 64 here with the help of one through the door leaf 12 externally guided actuator, such as Handle, swivel lever (see Fig. 4) socket wrench (Fig. 3) or the like. Rotatable, the Rizel, the in corresponding perforations or serrations 66 engages the rod 18, this up and down pushes.

The lock nut, pinion and rod bearing 60 consists of as shown in FIG. 3 a base portion 68 into which one end of the Locknut 64 stores, and one on the base part 68 attachable cap part 70, which means Screws 72 is fixed to the base part and that other end of the nut stores. As from the sectional view A-A ker Fig. 2 emerges, that forms Lock nut, pinion and bar bearings 60 too Guide slots 74 and 76 for optional insertion rod 18 either in the illustrated Way in which the closing direction is clockwise follows, or in channel 74, where one vice versa closing direction for actuator arises.

About this turning of the continuous bar 18 and in this way a change in the direction of rotation regarding the actuator to enable the rod 18, see also 8 and 9, executed twice axially symmetrical be, namely once around the longitudinal axis 78, on the other about the transverse axis 80. Die Here, symmetry also includes punched-out Stop lugs 84, which are on the outer surface of the lock 16 and thereby the path of movement limit the pole like that Cranking 82, which gives the freedom for the Arrangement of the pinion 62 result. As well the holes are affected by the symmetry 86, 87, which are used to record the described double roller pin 40 provided are. The path of movement of the rod can, however also be limited in that the rod perforation 66 of the rod 18 only n teeth each 67 (where n = 5 according to FIG. 36), of one of which has two opposing teeth have flattened stop surface 69. The The stop surface can preferably be flattened strike the rod plane 71 if the one in the last perforation hole adjacent tooth just perpendicular to the plane of the bar stands.

In Fig. 11 are the two arrangements described the rod 18 shown, which also double rolling pin 42 show.

The base part 68 is in a plan view in FIG. 12, an axial sectional view, a rear view and shown in a cross-sectional view. The base part shown here serves, as can be seen, for a double-bit lock and covers the second rectangular hole 34 at the same time, by using a one-piece cover plate 88, which turns into a hook 90, behind the bottom of the opening 34 sets while the upper end of the base part 68 through the rectangular Passes through opening 32 and with a Edge 92 covers. For storing the lock nut 64 serves a circular depression 94 while a further depression 96 of reduced diameter for receiving the head 100 one Double bit key insert 98 is used with another part of this head, which is also a Circumferential groove 104 for receiving a possible Has O-ring seal, as well as with a foot part 102 in the pinion 64, see Fig. 17, torsionally rigid is stored and with the help of a not shown here Screw in a blind threaded hole 106 can be screwed in, and with the help of a Square connector 108 a torsionally rigid connection between these two components 64 and 98 enables. The components could also be in one piece be, however, the advantage of this combination from two parts of that the insert 98 that here is intended for a double bit key, in can be exchanged easily against a bet for another key type, so that the pinion 64 for very different Key types can be used. So can for example instead of insert 98 according to 16 the pivot bearing of a pivot lever lock, as shown in Fig. 4, can be used, see Fig. 18. This pivot bearing 110 with the associated pinion 64 (FIG. 15) can then be inserted into a base part 168 which is shown in more detail in Fig. 17. This base part 168 again directed the depression 94 and one Storage area 96, but also has one Spherical surface 112 around a pivot lever 114 to be able to store.

The base part can also be designed that it's for using different key catches is suitable, see those in FIGS. 17 and 28 and 29 embodiment shown with the Reference number 168 or 468 and component 368 and 668 in Figs. 20 and 31, respectively, on which components is received later.

The base part 68 in its various configurations is usually made of plastic be sprayed and in this case e.g. injected Blind holes 116 or through holes 18 have the fastening screws 72 creating their own thread incise. If you spray the parts out of metal, will you get corresponding thread sack or - Provide through holes.

The plastic essentially allows one wear-free and requires little friction Plain bearing.

There are cabinets that are only rectangular Have breakthrough 32. In this case needs a second breakthrough 34 is not covered too become. A simplified basic part is then sufficient, that does not have the cover plate 88. It can also be designed in this way, see FIG. 19, that a cover plate 188 subsequently in a corresponding depression 120 inserted can be. The base part shown in Fig. 19 268, the base part in terms of nut storage 68 corresponds to FIG. 12, has a special feature a total of four projections 122, the two Hold spring clip 124. Grind the spring clips on the circumference of the nut 264, with flattened areas 128 is provided, in which the spring 124, such as shown on the right in Fig. 19, and so one Locked in four positions shifted by 90 ° causes.

3, 19, 20, 14 in different Base part describing embodiments 68, 268, 368 or 568 can be inserted into the or the openings 32, 34 in the door leaf 12 and Insert the desired type of lock nut 64, 264 and after appropriate attachment associated actuating rods 18 the cap part 70 or 170 are placed, which in Fig. 13 in to recognize a first embodiment in more detail is. The cap part 70 has in the cap base 130 a central opening 132 for the storage of the Nut and one above and one below the central one Opening 132 arranged and in the cap interior protruding eye 134 with a sunken Bore 136 for receiving the fastening screw 72 on. Go from cap bottom 130 two longer ones parallel to the guide slots 138 Sidewalls 140, as well as vertical shorter side walls 142, the latter on the Connect eye 134 and from their end edges one support protruding into the cap and guide wall 143 leads to the longer sidewall 140 parallel at a distance is arranged and with this part of the guide slot 138 forms. This part of the cap 70 fits e.g. to the base parts 68, 168, 268 3, 4, 17, 19, wherein the wall 143 to to the inner face e.g. the base part 68 enough. The one from the fastening screws 72 pressure applied is essentially from the end faces of the side walls 142, 140 on the edge areas of the door leaf opening 32 (according to FIG. 1) and serves to to hold the lock securely in the door leaf.

12 and 17 each is a little modified embodiment of the corresponding Recognize the base part, labeled with Fig. 27 and Fig. 28, compared to the previous modified base part in this respect are as the part reaching into the door leaf is shortened so far that the depression 94, the previously used for storage of the nut, no longer applies. These basic parts are for one embodiment provided, which is explained in more detail in FIG. 20, in which embodiment the base part in two parts is and from a key catch part 144 and a bearing part 146, which bearing part with the associated cap part 170 essentially same structure as shown in Fig. 21, the Cap portion 170 shows, and FIG. 22, the one Playback of the bearing part 146 is clear. The two parts only differ in that one part, here it is Bearing part 146, from the edges of the countersunk Bores 236 from the connection plane 145 for the two parts 146, 170 in the direction of other protruding noses or annular Protrusions 148 going out in the opposite part, here the cap part 170 arranged recesses, here accordingly extended countersunk holes 336, fits intervene and interlock of the two parts. But you can also through the countersunk holes 236, 336 rivets lead and through this the mutual Lock the parts, whereupon the both parts are made completely identical can. A pre-assembly would be with the help of hollow rivets the lock nut, pinion and rod bearing possible in the manufacturing plant.

Another advantage is that it may be pre-assembled Lock nut, pinion and rod bearings with various forming the rest of the base part Key catches can be combined can, as already shown in FIGS. 27 and 28 are shown. Because of the identity of the two Forming lock nut, pinion and rod bearings Parts are the manufacturing cost and the Warehousing costs further reduced and it arises a kit system that with very few Share extremely diverse application options allowed. So it can in Fig. 20 shown lock nut, pinion and rod bearings, consisting of parts 368 and 170, instead with the key catch part 144 shown there together with the associated square insert shown in FIG. 25 208 (which in the also in Fig. 25 shown completely symmetrical pinion 262 insertable is) with a swivel lever base plate 468 can be linked as alternative in Fig. 28 is shown and which pivot lever base plate 468 with built-in swivel lever 114 in Fig. 29 can be seen, the pivot lever pivot 210 differs from that in FIG. 18 shown pivot lever bearing pin 110th through an enlarged, to the bore diameter of the base part 146 adapted bearing part 150 and the square 152 starting from it for insertion into the corresponding square opening 154 of the pinion 262 shown in FIG. 25 differs. The swivel bearing is held 210 with the help of a square 152 Bolt on which a screw can be placed that can be seen in FIG. 29. Like Fig. 20 further clarified, can also the key catch part 144 in turn be multipart in order to be increased Achieve flexibility. 20 shows above on the right a key catch 144 with an insert 154, which is shown separately in Fig. 26 and the Key catch 144 on so-called double-bit keys, see reference numeral 156 in FIG. 26. In addition to the double-bit insert shown on the left 154 is a correspondingly modified one on the right Insert for square key shown, see the reference number 254.

23 shows the key catch 144 20 with insert 154 and square plug connection 208 again separately from the front and from the side, the key catch 144 too again a return 120 for recording possibly has a cover plate 188. Set up similarly could be an easier lockable one Lever lock, see Fig. 23 above. The one for the in 26 insert 154 and 254 provided Key catch with an appropriate Sinking for operations jumps 158 results from Fig. 24. This figure also leaves the more precise Form of the recess 120 for receiving corresponding Tabs 160 of the additional cover 188 detect.

14 shows a base part 568 similar to that of FIG Fig. 17, in which also interchangeable Key catches are provided. The base part is here especially narrow and the key catch rotation lock by axially towards the Locknut directed locking fingers 569, the section between them Form spaces 560 into the corresponding ones Protrusions of a key catch insert can intervene, realized.

31 shows a view from the front, from above and in axial section a swivel lever operation for the rod lock according to the invention, the special feature is a base part 668 has a cover cap at the lower end 669 for enclosing the cylinder 164, the cap 669 by means of screws 672 which into corresponding bores 616 (similar in Fig. 14, see there the reference number 516) of the base part 668 can be screwed in, on the base part is attached and the door leaf 12 jammed. Located in the upper area of the base part an O-ring seal in a suitable recess 673. Will now still be between the base part support surface and door leaf a sealing sheet placed that at least the openings 32, 34th surrounding areas 674, 675, and are the heads of the screws 672 tightly enclosed and is also between cap edge 676 and door leaf provided a seal, the closure also outside the canting space 10 and arranged within the sealing space 9 31, without the shutter would endanger the room sealing.

In the installation type shown is the use a wing tongue 8 possible. To do this the lock nut 664 so that they a bearing surface 676 with an axial prismatic Countersink and tapped hole for torsionally rigid Attachment of a wing tongue 9. Such a lock nut 664 can be made from a Swivel lever bearing similar to FIGS. 18 and assemble a pinion similar to FIG. 25 or 30 and in a lock case made of parts use similar to FIGS. 21 and 22. The Wing tongue 8 is with a shoulder 677 provided by means of the attachment Screw 678 on the pinion and at the same time forms a pivot bearing surface in the lock case part 670.

With symmetrical lock cases as in Fig. 31 the lock nut 664 must be relatively wide with respect to the outer surface of the lock case spring back so that - with pin closures - the Thorn does not protrude too far. Hence also the steep penetration of the wing tongue attachment 677.

The rod lock described can be particularly simply thereby in the tilting space mount a sheet metal cabinet door that first the rod guides 20 over the rods 18 are clipped, then the rod guides 20 put on the studs and screwed with a nut (or alternatively with a bolt fixing that) that then the key shield Base part 68 (if necessary after inserting the corresponding Additional parts such as mandrel insert 154, bearing part 146 and / or cover plate 188) mounted from the outside is that then the pinion 62 with the associated Actuating pin, e.g. 208 in Fig. 26 and then the cap part 70 put on and all by means of the two screws 72 is set. The control cabinet door panel firmly between the key plate or Base part 68 and the put-on cap part 70 and possibly jammed 669. From the poles up displacement forces transmitted to the lock are taken up by the base part, not from a compression fitting like with State of the art, so that compared to older ones Constructions the risk of loosening the fastening is not given.
