Abstract
The disclosure relates to a swivel lever actuator which can be secured by a padlock for the closure of switch cabinet doors or the like, with a dish which is arranged on the outer surface of the door leaf or the like and in which is arranged the lock shaft, wherein an actuating lever is articulated at the free end of the lock shaft as to be swivelable out of the dish about an axis extending transverse to the shaft axis, and with a projection supported by the dish, wherein an eyelet is arranged at the free end of the projection in such a way that when the lever is swiveled into the dish the projection and a padlock inserted through the eyelet prevents the actuating lever from swiveling out. The actuating lever, forms an offset surface in the area of the opening, which offset opening receives the shackle inserted through the eyelet.
Description




This application is a 371 application of PCT/EP98/02709.




BACKGROUND OF THE INVENTION




a) Technical Field




The invention is directed to a swivel lever actuator which can be secured by a padlock for the closure of switch cabinet doors or the like, with a trough or dish which is arranged on the outer surface of the door or the like and in which is arranged the driving device for the closure, such as a toothed-wheel drive, lever drive or lock shaft, wherein an actuating lever is articulated at the driving devices so as to be swivelable out of the dish about an axis extending parallel to the outer surface of the door or the like, and with a projection mounted on the dish, wherein an eyelet is arranged at the free end of the projection in such a way that when the actuating lever is swiveled into the dish the projection extends through an opening in the actuating lever and a padlock inserted through the eyelet prevents the actuating lever from swiveling out.




b) Description of the Related Art




A swivel lever actuator of the type mentioned above which can be secured by a padlock is already known from page 2-105 of a catalog from DIRAK GmbH & Co. KG, Kaiserstr. 55-59, 58332 Schwelm. A disadvantage in this known arrangement is that the projection projects far over the surface of the swiveled in swivel lever and accordingly presents an obstacle to persons passing by. Due to the fact that the projection in the center of the dish projects out very far, it also impedes the user's hand when the lever is swiveled out.




A closure for sheet-metal cabinet doors having a retractable or lowerable handle is known from DE 42 10 588 C2. This patent centers around the set of problems associated with the displaceable cover cap for a keyhole. Also described, however, is the possibility of fixing the swivel lever in the swiveled in state by means of a hook which can be swiveled out of its fixing position by the locking plate of a cylinder lock, whereupon the swivel lever is released.




A swivel lever closure which can be fixed in a swiveled in position by means of a cylinder lock and the locking plate thereof is known from EP 02 61 267. A hook device which hooks in automatically when the swivel lever closure is swung in is not provided. Also absent from this reference is an arrangement in which the swivel lever can be secured by means of a padlock.




It is known from WO 91 17 334 A1, see FIGS. 4 to 6 and claim 15, that a locking strip has a cam surface which is engaged by an edge formed by the base plate or by the opening in the door leaf when the swivel lever is swiveled into a lowered or recessed position and is accordingly pressed into the unlocked position against the spring force of a spring and that the cam surface is released again when the swiveled in position is achieved. Accordingly, locking can easily be carried out in this case by swiveling in the swivel lever. A key is not required for locking. However, it is not possible to lock the swivel lever by means of a padlock.




FR 25 84 093 A1 shows, in FIGS. 1 and 2, an actuating lever which can be fixed in a determined position by a padlock.




U.S. Pat. No. 4,134,281 describes a folding lever, that is, not a swivel lever. In the folded in state, the folding lever can be held by a locking lever 64 mounted in the dish as well as by a cylinder lock 66 which is accommodated in the folding lever. The folding lever can be accommodated in a housing


70


in a recessed manner. The cylinder lock 66, with its locking plate


130


, represents a first locking member. In normal use, this locking member holds the handle 16 in its swiveled in position. The folding lever is unlocked by pressing on a surface 96 of the structural component part 64. This is shown in FIGS. 6 and 4. The lever 64 has an opening 150 which, however, is not disclosed more fully in the description. Presumably, a shackle of a padlock can be placed through this opening in order to secure the lever against unauthorized opening. The folding lever 60 is provided with a bent back portion which can be seen in FIG. 4, but which is not discussed more fully in the text. As is stated in the abstract, this is a door closure for truck doors.




U.S. Pat. No. 5,467,623 relates to a swivel lever actuator which is locked in the swiveled in state by a locking lever 27 which is accommodated in the swivel lever. The locking member 33 of a cylinder lock 20 engages in the movement path of this locking lever, preventing its actuation, and therefore prevents the release of a hook device which engages behind a back-engagement 35 in the swiveled in state of the actuating lever and is held by the back-engagement 35. When the locking member is turned away, the lever 27 can be swiveled by thumb pressure out of its position in which it is held by the spring 35 against the force of a helical spring 26, whereupon the swivel lever is then swiveled out by means of an additional pressure spring 18 which is arranged in the area of its swiveling axis. A device enabling additional locking by means of a padlock is not described.




U.S. Pat. No 5,440,905 describes a swivel lever with a locking mechanism 11 which releases the swivel lever from its locked position by means of pressing a button on the swivel lever. A cylinder lock displaces a bar 20 behind which the projecting part of the push button engages. By means of a cylinder key, this slide can be displaced in such a way that it is no longer possible to unlock by means of the push button. This reference also does not offer the possibility of additionally securing the swivel lever by means of a padlock.




OBJECT AND SUMMARY OF THE INVENTION




An essential object of the invention is to further develop an arrangement of the type mentioned above in such a way that the projection with the eyelet through which the padlock can be inserted is less obtrusive.




This object is met in that the actuating lever forms an offset surface in the area of the opening, wherein the shackle of the padlock which is inserted through the eyelet is received by the offset surface in a well fitting manner.




According to a further development, the dish can also have, in the area of the shackle, a countersink or recess which receives the shackle in a well fitting manner.




A further disadvantage in the known arrangement consists in that security against swiveling out is only present when a padlock is actually inserted.




There are also cases where a padlock of this kind is not to be provided, at least occasionally; in such cases, the known arrangement is not protected against an unwanted swiveling out of the swivel lever. A swiveling out of this kind can occur when the swivel lever exits the dish due to a shaking movement such as can occur during an earthquake or also during operation on vibrating machinery, resulting in the risk that the swivel lever will rotate to the extent that the closure device opens and the door leaf or switch cabinet device secured by the closure remains open. Switch cabinets located, for example, on crane installations where there are often a plurality of, e.g., as many as


30


, switching installations which are enclosed by a switch cabinet are exposed to particularly violent shaking movements. Unwanted opening of such switch cabinet doors due to shaking cannot be tolerated. In the known arrangement, it is possible to provide a profile cylinder which can likewise secure the actuating lever independent from the padlock. However, the combination of a swivel lever closure with a padlock as well as a profile cylinder makes the arrangement complicated because two keys are then necessary: a first key for the padlock and a second key for the profile cylinder. The known arrangement also does not allow the actuating lever to be simply pressed in and locked. If a key-operated arrangement is provided, it must first be closed by means of keys or a padlock must be attached in order to achieve locking.




Therefore, another object of the invention is to further develop the known arrangement in such a way that the actuating lever can be pressed into its closing position and held therein so as to be secured also without the use of a padlock and without the use of a key-actuated cylinder.




Further, it should be possible to remove the actuating lever from this pressed in secured position without the need for special tools.




These additional objects are met according to another embodiment form of the invention in that a hook is provided at the actuating lever, which hook engages a back-engagement surface of the dish when the actuating lever is swiveled in and accordingly holds the actuating lever in the swiveled in position.




When the hook has an actuating surface, wherein the hook is released from the back-engagement surface when the actuating surface is pressed, the swivel lever can be released again in a simple manner without additional tools.




The releasing movement of the hook is advantageously carried out against spring force because the hook is then held in its locked position more securely.




It is also advantageous when the actuating lever can be swiveled in against spring force because it then swivels out of its locked position when the lock is released without further manipulation.




It can be advantageous when the actuating lever also has an additional lock which can be actuated by means of a tool. This provides additional securing means which, although less secure than a padlock, still make it possible when a padlock is not available to lock in such a way that it cannot be opened without a tool.




It is advantageous in terms of construction when the dish has two protrusions which extend through the door leaf or the like, wherein one protrusion forms a lock shaft support and the other protrusion is formed by the fastening for the projection for the eyelet. This prevents rotation of the dish on the door leaf and, on the other hand, provides a fastening by means of parts which are already present and accordingly enables a twofold use of certain elements of the closure.




The protrusions can form circumferential threads on which fastening screw nuts can be screwed, wherein the door leaf is clamped between the fastening screw nuts and the dish. This results in a particularly simple assembly of the arrangement.




The swivel lever actuator according to the invention is suitable for actuating a quarter-turn or sash fastener, a flat rod closure or round rod closure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIG. 1

is a side view showing a swivel lever actuator


10


for the closure


12


of a switch cabinet door


14


, a housing wall (not shown), sheet-metal case cover or the like (not shown), with a dish


18


which is arranged on the outer surface


16


of the switch cabinet door


14


or the like and in which is arranged a lock shaft


20


which carries, for example, a sash


22


in a manner not shown in more detail and which, in this case, also drives flat strip lock rods


24


or, as is shown in

FIG. 3

, round rods


26


, extending along the door leaf. For further details in this connection, reference is had to the European Patent 0 054 225. For example, a tooth-wheeled drive 600 connected to shaft 20 may be used.




An actuating lever


28


is articulated at the free end of the lock shaft


20


directed away from the sash so as to be swivelable out of the dish


18


about an axis


30


extending transverse to the axis of the shaft


20


. In the swiveled out state which is shown in dashes in

FIG. 11

, the shaft


20


can be rotated with the actuating lever


28


about its axis


32


, for example, in order to swivel a sash


22


behind the door frame


36


(see

FIG. 2

) of a switch cabinet, not shown, and accordingly to close the door. Alternatively or in addition, a door closure position is achieved, as shown in

FIG. 1

, by flat strip rods


24


which can be moved upward and downward, wherein a stop wheel


34


runs up on the edge, shown in

FIG. 1

, of a switch cabinet housing


36


and holds the door leaf


14


at which the locking rod


24


is guided by means of rod guides


38


. In the embodiment form shown in

FIGS. 1 and 3

, the locking rods


24


are located in the locked position, while the actuating lever


28


faces downward (diagonally) as is shown in FIG.


11


. In this position, the actuating lever


28


can be swiveled into the dish


18


, in which position the actuating lever


28


is substantially enclosed by the dish edges. The devices described in the following should serve to hold the actuating lever


28


in this swiveled in position in which the actuating lever


28


is prevented from being rotated out of its position oriented to the dish due to the fact that it is enclosed by the dish edges. Therefore, it is not possible for the door to be opened.




When the actuating lever


28


is in its position in which it is directed vertically downward, its own gravitational force and friction are sufficient in themselves to hold it in this position. However, during shaking movements such as those which can occur, for example, in crane installations, there is a risk that the actuating lever


28


will move out of its swiveled in position again and into the swiveled out position shown in dashed lines in FIG.


11


. In this position, rotation can also be carried out about axis


32


due to further shaking movement, so that the closure


12


opens in certain cases and therefore exposes the interior of the switch cabinet in an unwanted manner. It is also possible that an unauthorized person will swivel out the actuating lever


28


and move the door closure out of its closed position into an open position by rotating about the axis


32


and will accordingly be able to open the door


14


of the switch cabinet.




In order to prevent this, a projection


40


is provided. The projection


40


is supported by the dish


18


and is provided at its free end with an eyelet


42


in such a way that when the actuating lever


28


is swiveled into the dish


18


this projection


40


extends through an opening


44


in the actuating lever


28


and the shackle


46


of a padlock


48


can be inserted through the eyelet


42


so as to prevent the actuating lever


28


from swiveling out.




As can be seen in

FIGS. 1 and 3

, but especially, e.g., in

FIGS. 5 and 7

, the actuating lever


28


according to

FIGS. 1 and 3

, designated by


128


in

FIGS. 5

,


6


and


7


, is outfitted in the area of the opening


44


for the projection


40


with an offset surface


50


which is constructed (see

FIG. 5

) in such a way that it receives, in a well fitting manner, the shackle


46


of the padlock


48


passing through the eyelet


42


. This reduces the height of the projection


40


and therefore the degree to which the eyelet


42


projects over the front plane


52


of the actuating lever


128


, for example, in this case to a distance a (see

FIG. 7

) which equals approximately half the diameter of the cross section of the shackle


46


.




As can be seen in

FIG. 5

, the edge


54


of the dish


118


is countersunk (see reference number


56


) in the area of the eyelet


42


, so that the extent to which the eyelet


42


projects out can be further reduced if necessary.




The great advantage in securing by means of a padlock


48


consists in that an individual padlock


48


belonging to a certain person can be used, for example, at certain times and for certain reasons, so that it is possible for this person to secure a door against unauthorized opening. Only this person can open the padlock again by means of the key belonging to this padlock, remove it and then open the door closure by folding out and subsequently turning the actuating lever. If a special securing of this kind is not required at certain times, a padlock can also advantageously be dispensed with. In order for the actuating lever to be held in the swiveled in position in this case, a hook device


58


is provided, e.g., at the swivel lever


128


, which engages with a back-engagement surface


60


of the dish


118


when the actuating lever


128


is swiveled in, thereby holding the actuating lever


128


in the swiveled in position. The hook


58


which in this case is held so as to be swivelable about an axis


62


formed by the actuating lever


128


has a first actuating surface


64


which projects over the end of the actuating lever


128


and is directed in such a way that the user must grasp under this surface


64


of the lever


66


corresponding to an opening movement of the hand lever


128


in order to swivel the hook


58


out of its locked position (in the counterclockwise direction with reference to FIG.


5


), wherein this pulling direction not only swivels the hook


58


out of its locking position, but also subsequently pulls the actuating lever


128


out of its swiveled in position after the hook is undone. This operating sequence is intuitive for the user and therefore represents a particularly advantageous embodiment form of this hook device


58


.




The hook


58


can also be swiveled out of its locking position by a pressing movement in the direction of the hand lever surface


52


by means of a second actuating surface


70


which is provided in this instance and which projects beyond surface


52


. Further, the additional lever arm forming this actuating surface


70


has, on its back, a recess


72


in which one end of the above-mentioned pressure spring


68


is received, while the other end of the pressure spring


68


is held on a protuberance


74


which is formed by the actuating lever


128


.




The actuating lever


128


can be provided with an additional spring device in the area of its axis


30


in order to move the actuating lever


128


out of its swiveled in position automatically when required. In this case, when the actuating surface


70


of the hook


58


is pressed, this hook is released and the spring action presses the actuating lever out of its swiveled in position insofar as it is not impeded by an inserted padlock


48


.




As is shown in

FIGS. 6

,


7


and


8


, a further locking possibility can be provided. This relates to a head pin


76


which is arranged approximately in the center of the actuating lever


128


and which may be mounted so as to be rotatable in a countersunk opening


78


of the actuating lever


128


. The free end of the pin


76


has a cross-pin


80


which can be received in a determined position of the head pin


76


when the actuating lever


128


is swiveled into an opening


82


of the dish


118


. The area of the dish


118


forming this opening


82


juts out somewhat so that back-engagement surfaces


84


are formed, wherein the ends of the pin


80


are located behind these back-engagement surfaces


84


when the head pin


76


is rotated by 90°. Accordingly, this is a kind of quarter-turn closure which makes it possible to lock the actuating lever


128


in its swiveled in position by means of this head pin


76


. The rotation of the head pin


76


into and out of the locking position is carried out by means of a tool, in this case, a screwdriver, not shown, which is inserted into a slot


86


of the head pin


76


. However, this purpose can also be met by a bar or a swivelable tongue when it can be moved against spring force by a cam or a connection which is rigid with respect to rotation, possibly with freewheeling.




According to

FIGS. 1 and 3

, the dish has a protrusion


88


which extends through the door leaf


16


where it is part of a lock shaft support and, e.g., according to

FIG. 1

, communicates with a lock case, wherein the door leaf


16


is clamped between the lock case and the dish


18


so that the dish is held firmly. The opening provided in the door leaf for this purpose is rectangular in this case, similar to that required in the construction according to the above-cited European Patent 0 054 225. According to

FIG. 3

, a construction is provided in which a disk


13


is provided instead of a lock case, wherein the sash tongue


22


on the one hand and projections for the articulation of the round rods


26


on the other hand proceed from this disk


13


.




According to

FIGS. 7 and 8

, the dish


118


has a projection


188


which has a circular outer cross section and an external thread, possibly with flattened portions


187


, so that the projection


188


can be used in conventional openings in the sheet-metal cabinet doors provided with necked down portions. A fastening screw (cap nut or union nut) can then be placed on the projection


188


and the door leaf can be clamped between this nut and the dish support surface


118


.

FIG. 11

shows an example for a fastening of this kind by means of a union nut


90


.




The projection


40


carrying the eyelet


42


can be formed integral with the dish


118


. However, for purposes of strength (e.g., when the dish is made of plastic), it is generally preferable that this projection


40


is provided as a separate structural component part, for example, as a metal projection which proceeds from a base plate


92


. This base plate-can be inserted into a corresponding recess


94


of the dish


118


from the rear in such a way that its surface area is aligned with the surface area of the dish


118


(see FIGS.


7


and


8


). The plate edges are then held by the projecting edges


96


of the dish


118


. Alternatively, the projection


40


could also be injected into the material of the dish


118


.




It is noted that when the actuating surface


70


is present, the projection


66


forming actuating surface


64


can also be omitted. This makes the actuating lever


128


somewhat shorter as a whole.




The padlock


48


shown in

FIG. 7

projects out diagonally. The lock is accordingly somewhat easier to access but, on the other hand, has the disadvantage that it forms an impediment by projecting outward.




If this jutting out is troublesome, an embodiment form shown in different views, e.g., in

FIGS. 9

,


10


,


11


and


12


, is advantageous. The main difference between this embodiment form and those shown in

FIGS. 5

to


8


consists in that the projection


140


is relocated to the lower end of the dish


218


so that the padlock


48


has room to hang down freely. The lower end


65


of the actuating lever


228


, with reference to the Figures, is bent away somewhat from the door leaf


14


and the dish and accordingly makes it easier to pull the actuating lever


228


out of its swiveled in position after the padlock


48


is removed from the eyelet


142


.




The eyelet


142


is designed in this case in such a way that it is formed by a projection


140


with a base


192


whose shape can be similar to that of the protrusion


188


in which the lock shaft


32


is supported, that is, with an external thread and, if required, two or four flattened portions, wherein a fastening nut


190


can be screwed onto the external thread so that the door leaf


14


is clamped between the fastening nut


190


and the dish


218


. The dish


218


is held in turn by a ring


193


which is formed by the base


192


and is received in a corresponding recess


194


in the interior of the dish.




The advantage of the construction shown in

FIG. 9 and 10

is, for one, the greater stability provided by fastening by means of two protrusions


188


,


192


which project over the support face of the dish and which are provided with a union nut


90


and


190


, respectively, and, on the other hand, the fact that the padlock


48


does not project out as much.




Another advantage consists in that the closure can be used as a left-hand closure or right-hand closure in case the openings for the protrusions are arranged symmetric to the center of the door.




It is noted that the inner area of the switch cabinet can be sealed relative to its outer area by means of sealing rings


95


between the outer surface of the door leaf and the dish in the area of the protrusions


188


and


192


insofar as the shaft


32


at which the hand lever actuator


228


is articulated at


30


and to which the sash


22


may be fastened by screws


21


is outfitted with an O-ring seal


23


.





FIG. 12

shows a somewhat modified embodiment form in which the projection


240


is supported by the dish


318


in a similar manner to the projection


40


according to

FIG. 7

instead of by fastening with a union nut


90


. The dish


318


itself is held at the upper end by a nut


90


similar to

FIG. 11

, but is held at its lower end by a screw bolt


91


which is arranged with its bolt head on the back of the door leaf


14


and whose threaded part extends into a corresponding threaded bore hole


89


inside the material of the dish


318


.




While the eyelet of the protrusion


140


projects beyond the surface of the actuating lever


228


by a distance a in the embodiment forms in

FIGS. 9

to


12


, this is no longer the case in the present embodiment form shown in

FIGS. 13

,


14


and


15


. The protection


340


is shorter and accordingly makes it possible for the actuating lever


428


and the dish


418


to be recessed more deeply for the shackle of the padlock


48


than was the case in the preceding embodiment forms. Additional space is created in that the front area


465


of the actuating lever


428


extends into a recess


497


of the dish


418


and accordingly retains sufficient material strength. The upper area of the eyelet


340


accordingly no longer projects over the upper surface of the actuating lever


428


.




The padlock


48


also remains below the alignment line of the front surface of the swiveled in actuating lever, so that an extremely flat embodiment form results.




As is shown in

FIG. 11

, this embodiment form can also be constructed that is, with two protrusions for openings in the door leaf which are constructed, if required, so as to be identical in size for fastening by means of two nuts


90

. Due to the arrangement of two identically sized holes which are advisably arranged symmetric to the center of the door, the closure can be switched from right to left in a simple manner.




This extremely flat version is particularly well-suited to be arranged in flush paths because there are no projecting parts to impede persons passing by quickly.




Due to the low height of the projection compared with the prior art, this is also less troublesome for the user's hand when the actuating lever is folded up and turned. Moreover, since the projection is at a further distance from the point of articulation of the actuating lever than in the prior art, there is more space between the actuating lever and the projection, so that the projection is also less troublesome for this reason.




The swivel lever lock according to the invention can also be used in closures which are actuated already when the actuating lever is swiveled out of the dish, that is, which do not require subsequent turning of the swivel lever.

The invention can be used commercially in switch cabinet construction.




While the foregoing description and drawings represent the present invention, it will be obvious to those skilled in the art that various changes may be made therein without departing from the true spirit and scope of the present invention.
