Provided with lock mechanism

retractable swivel lever lock

TECHNICAL AREA

The invention relates to a lock device, such as

Cylinder lock, provided retractable swivel lever lock for mounting in preferably two, preferably rectangular openings in a thin wall, such as a sheet metal cabinet door, in particular in the tilting space of such a sheet metal door, consisting of a mountable on the door leaf

Base plate which has a front recess for the recessed reception of a hand lever, the hand lever on one penetrating the door leaf and the base plate

Actuating shaft for the actuator of the closure is pivotally mounted perpendicular to the axis of rotation of the actuating shaft and the hand lever can be locked and released in the recessed position in the recess by means of the lock device arranged in the hand lever.

STATE OF THE ART

A pivot lever lock of the above type is from the

EP 0 261 266 A1 is already known. DE 34 07 700 A1 also shows a swivel lever lock, but this is the one

Lock device not arranged in the hand lever, but in the base plate. In some applications it is now necessary to use the

To be able to supplement the pivot lever lock so that it can be locked or unlocked with more than one, for example with two lock devices, such as cylinder locks, the cylinders each having their own cylinder key. Such an application is e.g. B. given if a control cabinet by both a representative of

Electricity plant must be kept accessible, which must be able to lock or unlock the swivel lever lock with the help of a cylinder and the associated key, so as to be able to gain access to the control cabinet, and on the other hand by the user or customer of the electricity plant who works with must also be able to use his own key. to be able to access the inside of the control cabinet if necessary, using his own

Key that does not match the key of the electricity company. The power plant could expediently work in numerous switch cabinets, which can also be at different customers, with cylinders, all of which can be opened with a single key. The customer can turn the standing in his area

Control cabinets with uniform or different cylinders, which can be operated by their own master key, or different ones

Keys assigned to the respective operator.

Rod locks for two profile cylinders, optionally lockable by one or also by two cylinders, are described in a Steinbach & Vollmann catalog, mentioning that such a special lock can optionally be locked by one or two cylinders. The rod lock is intended for doors in which the actuation is required by two different cylinder keys. On other pages, the catalog also contains a bolt lock with two cylinders for similar purposes, as well as one Mortise lock, which also works with two cylinders. Regarding mortise lock No. 651 / 2E748, which for

High-voltage systems with emergency release device is provided, it is mentioned that this lock can be opened from the inside, even if locked, by a handle. from the outside only with a key. According to this document, the lock can optionally be closed by one of the two cylinders, one cylinder for the owner of the switchgear and one cylinder for the energy supply, in each case in an existing or to be created locking system.

In all three embodiments of the type mentioned, be it as a mortise lock, a bolt lock or as a bar lock, the arrangement is disadvantageous insofar as the lock case provided is very wide, requires complicated assembly and, for example, in the case of the bar lock in addition to the two openings for the cylinders four more

Breakthroughs required to attach the lock case.

In modern switch cabinets, however, the smallest possible number of openings is sought, for reasons of the cheaper manufacture of corresponding door leaves, simplified installation and also for reasons of improved

Sealing against impermissible gas penetration through such breakthroughs. In addition, because of their large dimensions, the known rod locks working with two cylinders cannot be used in control cabinets in which the locking rods are to be arranged in the canting space of the sheet metal cabinet door. After all, the well-known rod locks working with two cylinders are not swivel locks, which are mostly preferred today because they are easy to install, take up little space and only protrude a little over the front of the cabinet.

PRESENTATION OF THE INVENTION

The object of the invention is to provide a pivot lever lock of the type mentioned in that it with Several, preferably two, lock devices, in particular cylinder locks, can be equipped without the other advantages of a swivel lever lock having to suffer significant drawbacks, such as the ability to be brought into the canting space of sheet metal cabinet doors if required, simple assembly, simple manufacture of gas tightness.

The object is achieved in that in

Hand lever at its free end in addition to the first lock device, such as a cylinder lock, a second lock device, such as a second cylinder lock, is provided so that the thumbs of the two lock devices, such as cylinders, each engage a common locking bar which locks the swivel lever in the lowered position and thereby (e.g. against gravity or spring force) can independently push this locking bar out of the locking position.

The arrangement of such a locking bar, which can be actuated independently by the two thumbs against gravity or spring force. allows a very compact

Structure, so that the overall arrangement, in contrast to the prior art, does not have to be accommodated in the lock case, but can be accommodated in the hand lever.

According to a development of the invention, the locking bar has a U-profile in cross section, and the bar is held axially displaceably on the pivot lever with the bar sides forming the legs of the U-profile. This construction is particularly stable and also enables an axially symmetrical arrangement in a simple manner, so that the lock can be used both on the right and on the left in a simple manner.

According to yet another development of the invention, both sides of the bar are provided with openings into which the Thumb of the two cylinders can intervene. This measure allows an even greater compactness and enables accommodation in a pivoting lever which is suitable for a series of locks which is conventional in the canting space

Tin cabinet doors can be mounted in two appropriately shaped and stacked openings.

If a particularly narrow construction is not required and one would like to keep the swivel lever shorter, an embodiment would also be conceivable in which the cylinders are not arranged one behind the other, but next to one another with respect to the swivel lever longitudinal axis, and the one cylinder with his thumb into an opening in one side of the last and the other cylinder engages with his thumb on an opening in the other side of the groin.

According to another embodiment, however, the cylinders are arranged one behind the other with respect to the longitudinal axis of the pivoting lever and the one cylinder engages with his thumb in a first opening on one side of the strip and the second

Top hat with his thumb in a second opening in that one ledge side. With this construction, it is easily possible to provide a third (possibly also further) cylinder, which then also fits into this one

Intervene on the groin side.

For right-left installation, as already mentioned, it is favorable if both sides of the bar have openings for the thumb.

For reasons of stability, it will usually be expedient to design the bar in the form of an elongated box, one narrow side of which is preferably the free end of the

Hand lever pointing narrow side, a contact edge or

Has system nose for reaching behind a solid part of the trough or a door leaf back surface. On the narrow edge opposite the locking lug or edge, the box can have an attachment for receiving a compression spring, such as a spiral spring, which with its other end adjoins a non-displaceable part

(Swivel lever base) of the swivel lever. This measure makes the assembly direction of the swivel lever independent of the effects of gravity.

In at least one of its side walls (e.g. between the thumb openings), the box can have one or more further openings to enable the insertion or removal of fastening screws which hold cylinders in the lever base body.

The side walls can have one or more longitudinal slots near their free leg ends for receiving the end of a guide pin, which is held in the lever base body. This forms a particularly good guide for the locking bar. To increase the stability and to form cam tracks for the cylinder thumb, the box between the two thumb openings can also have a reinforcing transverse wall. For each lock cylinder, the lever base body can have a breakthrough adapted to the cylinder contour and extending from the lever front surface to the rear for inserting the cylinder either from the front or from the rear, advantageously projecting from the back surface, which encompass the cylinder in the area in which it has its fastening thread opening.

The compactness of the arrangement serves if the projections cover both thread opening sides and if one cover has a first opening for a cylinder fastening screw and the other cover has a second opening for a cylinder fastening screw. If the two openings are arranged radially offset from one another, it becomes possible to selectively mount and fasten different standard cylinders (e.g. one on the one hand

Cylinder with a length of 40 mm, on the other hand one

Cylinders with a length of 45 or 47 mm).

A cover can be pivoted in front of the front surface, which covers the cylinders and thus protects against dust and rain.

The cover can also have depressions for receiving cylinders projecting over the front surface.

With cylinders housed in the hand lever, the overall length of the entire arrangement will remain relatively short. The greater weight of the hand lever may be disadvantageous due to the presence of the two (or more) cylinders at the end of the hand lever. It can also be annoying to insert the two keys in the hand lever

press and then swivel the hand lever with these keys. Therefore, an embodiment is also conceivable in which the two (or more) cylinders are not accommodated in the hand lever, but in the base plate, which increases the overall length, but relieves the hand lever of the presence of the cylinders. For the rest, however, the construction is to be designed entirely analogously.

Thus, a pivot lever lock according to the type mentioned above could also be designed such that a second lock device, such as a second cylinder lock, is arranged in the base plate near the free end of the hand lever in addition to the first lock device, such as a cylinder lock. whereby the thumbs of the two cylinders engage in a common locking bar that locks the pivoting lever in the lowered position and do so independently (e.g. against gravity or spring force) Slide this locking bar out of the locking position.

The base plate is, as in the prior art, preferably provided with two approaches that extend through the preferably two openings in the door leaf, one approach preferably part of the lock case and the other approach either the receptacle for the in the end

Swing lever arranged cylinder locks forms, or even carries the cylinder locks. As with the state of the

Technology is also possible here to provide the approach for the locking devices with a cap attachment which sealingly encloses the part extending through the wall. The edge of the cap attachment can rest against the edge surface of the thin wall surrounding the opening and thereby clamp the wall between itself and the base plate. Alternatively, the attachment can also have threaded bores for receiving fastening screws which press the kapoe against the wall or the attachment.

The openings will generally be the same width, but have different lengths, in particular the

Breakthrough, in which the cylinders are housed, is equipped with an approximately double longitudinal extension, like the second breakthrough, which is penetrated by the actuating shaft.

The swivel lever lock according to the invention can be used in many ways and can supplement an existing program that uses a swivel lever lock with only one cylinder locking device.

1 shows an embodiment of a swivel lever lock 10 designed according to the invention, which is arranged in two rectangular openings (see FIG. 4) 12, 14 in a thin wall, such as door leaf 1 6 of a sheet metal cabinet door and consists of a base plate 18, which base plate can be placed on the door leaf 16 and has a front recess 20 for the recessed reception of a hand lever 22, the hand lever 22 on one

Door leaf 16 and the base plate 18 penetrating the actuating shaft 24 (only the axis line is shown here) for the actuator of a closure, not shown here, such as a rod closure. wherein this hand lever 22 is in turn pivotally mounted perpendicular to the axis of rotation 24 of the actuating shaft (see pivot axis 26, for example, shown in FIG. 3). The hand lever 22 can be actuated by means of lock devices, for example by means of cylinder keys 28, 30 in the recess 20 recessed position, which can be seen in Fig. 2, lockable and releasable.

The base plate 20 points through the openings 12, 14

through-reaching approaches 32, 34 which fit in these breakthroughs and thus the

Center the base plate with respect to the door leaf. One approach, which extends through the opening for the actuating shaft 24, can also be part of a lock case, as shown, for example, by EP 0 261 266 A1, while the other approach (34) has a receptacle for the free end of the pivot lever 22 and the cylinder locks 36, 38 arranged therein forms. In the embodiment shown in Figures 1 to 4, the base plate 18 is held in the door leaf or the thin wall 16 in that the lock case (not shown here) is placed on the extension 32 and / or a cover cap 40 is placed on the extension 34 which, in turn, similar to the European patent publication mentioned, clamps the door leaf 16 centering between itself and the part of the base plate 18 resting on the door leaf.

5 to 7, a pivot lever lock of a similar type is shown, in which the cylinder locks 36, 38 are not housed in the pivot lever 122, but in the base plate 118, but with the cylinders (similar to that in FIG. 1 to 4 shown embodiment, there at least in the swung-in state) again through the second opening 114 not provided for the pivot axis 24 in the door leaf. As can be seen. here the second opening 114 required for the pivot lever lock is provided with a substantially longer axial extent, while the opening for the pivot lever actuating shaft 24, reference number 12, can have, for example, identical dimensions to the corresponding opening 12 according to FIG. 4. As will be explained in more detail, the width of these openings 12, 14 and 114 is relatively narrow and can be adapted to the customary dimension of 25 mm for already known pivot lever locks, for example according to the European patent mentioned. Correspondingly, the longitudinal dimension for the opening 1 2 can also have the usual values, for example twice the width dimension (eg 50 mm). This makes these closures more universally applicable and also allows a relatively problem-free subsequent exchange of already existing closures, which for example only have a cylinder lock, by closures according to the invention with, for example, cylinder locks, for which purpose only the opening 14 or 114 would have to be enlarged with regard to its longitudinal extent.

An embodiment will now be discussed in more detail in which two cylinders are mounted in the free end of the hand lever, as can be seen schematically in FIGS. 1 to 4 and will be explained in more detail in FIGS. 8 and the following. The two cylinders 36, 38 are arranged such that the thumbs, indicated schematically in Fig. 2 at 42 and 44, respectively, these two cylinders 36, 38 in a common, locking the pivot lever 22 in the lowered position

2, and engage (e.g. against the force of a spring or, if the hand lever is arranged substantially vertically with its longitudinal axis, possibly against the force of the

Earth gravity) independently pushes this locking bar 46 out of the locking position. The direction of displacement is indicated by the arrow provided with the reference number 48 in FIG. 2, that is to say the locking bar 46 can be displaced by a certain amount in the direction of the longitudinal axis of the pivoting lever 22 against, for example, spring force, the rest position, for example, the position shown in FIG. drawn with solid lines nete is, while the shifted against the spring force, for example releasing the pivot lever position in Fig. 1 is shown with dashed lines.

20, the locking bar 46 has a cross-sectionally U-shaped profile 50 so that it

Locking bar with the bar sides forming the legs 52 of the U-profile on the swivel lever base 54 in its end region receiving the cylinder locks can be axially displaceably supported against the force of a spring 56 by a measure 58, the locking bar 52 being dashed in FIG. 13 in its unlocked position , is shown against the force of the spring 56 shifted position. From this unlocking position, the spring 56 automatically moves the locking bar into a position to the right (not shown here) by the dimension 58. When the thumbs of the two cylinder locks no longer hold the locking bar 52 in the unlocked position. According to the embodiment shown here, the locking can be done, for example, FIGS. 17 and 19, by one of the locking bar 46 at its free end

Swivel lever 22 directed end formed nose 60 are formed, for example, over the edge 64 of the

Breakthrough 14 pushes and then lies against the edge region 62 of the door leaf 16 in the region of this edge. This

However, the contact surface can also be formed by part of the base plate 18, see for example the projection region designated by 66 in FIG. 8, which has the advantage that the locking function does not depend on whether the edge 64 of the opening 14 is formed correctly.

In order to enable the locking bar 46 to be displaceable, an embodiment would be conceivable in which the inner surfaces of the legs 52 form an edge or a recess which is suitable for a corresponding recess groove or edge in the side surface 68 aligned therewith A design is more favorable which, in addition to guiding the U-profile guide bar 46 in the axial direction with respect to the handle lever, also limits the displacement path and is also very space-saving, which is preferred in the applications envisaged here (installation in the canting space of control cabinet doors ) is of particular importance.

For this purpose, at least two, in this case even three, are axially spaced apart in the legs 52

extending slots 70 are provided in the locking bar 46, while in the pivot lever base 54 transverse openings 72 are provided at corresponding points penetrating pins which protrude into the slots 70 of both legs of the U-profile of the locking bar 46 and in this way on the one hand an axial Cause guidance, on the other hand, the axial displacement path (reference number 58) determined by the length of the slots 70.

As can be seen in Fig. 13, the two outer ones

Bores 72 are arranged in the area in which the insertion spaces 74 and 76 for the two cylinders 36, 38 run perpendicularly thereto, so that a split pin is to be provided here so that this space remains free for insertion of the cylinder and not through one across this space running pin is blocked. As can be seen in FIG. 14, enough wall thickness remains for the bore 72 in order to securely arrange this split pin or the two partial pins. At the middle breakthrough (designated 72 in Fig. 14). the openings 74, 76 for the cylinders are not detected and it is sufficient to insert a single pin, while the third opening (72) again requires a split pin.

The shape of the openings 74, 76 is adapted to the usual profile cylinder circumferential shape and therefore allows one push commercial cylinders, which are so-called half cylinders, ie cylinder locks that are operated from one side only with a key. These half cylinders are available in different standard sizes, the arrangement here being such that three different standard sizes can be installed.

These standard sizes differ essentially in that the distance of the mounting hole from the cylinder front surface varies. In order to be able to use at least two of these three standard sizes with only a single pivot lever base part and with a flush closure of the cylinder front surface with the front surface 78 of the pivot lever, the insertion space 74 or 76 provided for inserting the cylinders each has a first transverse bore for a cylinder lock of the first standard size and move you a little bit

Cross opening 82 for a cylinder of a different (smaller) standard size, As the illustration in FIG. 13 shows, the dimensions are such that the two bores 82, 80 come very close, but they do not overlap, so that sufficient material meat remains in order to give the fastening screw, which is passed through this bore 80 or 82, sufficient hold for the respective cylinder in the pivot lever base. It is expedient if, in addition, the head depression areas 180 to be provided for the cylinder head screws for the bore 80 or 182 for the bore 82 are on different sides of the pivot lever base 54; according to FIG. 16, it is the side 84 for the depression 180 and for the depression 182 page 86. Would the two depressions 180, 182 be on the same side

embarrassed, these depressions would at least overlap strongly and lead to an undesired weakening of the material.

In order to enable the thumb of the cylinder, not shown here, to pivot out, the side surface 84, 86 is eliminated in the region of the thumb arrangement, so that a Free space 88 or 90 arises, which begins at a point 92, that is the point at which the thumb edge of a cylinder emerges from the smallest space size to be used here. The space 88 or 90 then extends to the edge 94, which has the distance C from the front surface 78 of the swivel lever base 54, this distance can be chosen, for example, such that the cylinder profile fastened with the bore 80 fits exactly into the insertion space 76, this cylinder lock therefore has the length C. A shorter standard cylinder, for which the bore 82 would be provided, would not extend all the way to the edge 94, but would already end in front of this surface. There is a third standard size for a cylinder lock that would fit the bore 80 and that would also align with the edge 94 but would protrude slightly over the front surface 78. This is for many use cases

unproblematic.

The thumb of these three cylinder types can be excluded on the left or right, depending on the design, and then breaks through the plane of the side surface 86. To enable further pivoting, the two U-legs of the locking bar are provided with openings 94 and 96, the extent of which perpendicular to the direction of movement of the

Locking bar is selected so that the thumb can pass through for all locks to be installed, and its extension in the direction of the locking bar movement is selected so that the circle 98, see Fig. 18, the

Describes the outer surface of the thumb during its pivoting movement, from which opening 94 can be received. The movement of the thumb is therefore not hindered by the side wall. However, in order to be able to move the locking bar 46 with the thumb, the thumb 92 of the cylinder 38 can engage a cam surface 100 formed by an intermediate wall 101 and the corresponding thumb, not shown here, of the cylinder 36 can engage a corresponding cam surface 105 of an end wall 103 the spring already mentioned 56, which is carried on the one hand on a nose 107 carried by the end wall 103, but which is supported on the other hand in a depression 109 at its inner end, the locking bar 46 is in the direction of the arrow 111 and thus in the locking direction (see the locking nose 60 in FIG 19), unless a thumb against surface 105 or 100 prevents this. The one in Fig. 18

conditions shown show the position of the displaceable locking bar 46 with respect to the immovable cylinder 36 and 38, respectively, which unlocked the

Position represents: In this position the one of the

Thumb 92 formed circle 98 both freely through the opening 94, on the other hand it just touches the cam surface 100 and 105. d. that is, with the thumb pointing up from one or the other cylinder 36 or 38, the

Locking bar 46 also held in this position. The locking bar 46 only comes into the locking position when both cams 92 of the cylinders 36 and 38 have released the cam surfaces 100 and 105 completely, for which purpose the cam 92 points out of the upward direction

Position must be pivoted away by at least 45 °, see reference numeral 192 in Fig. 18. Since the cam 92 of the cylinder 38 is pivoted further away, the spring 56 can now the locking bar 46 along the pins sliding in the longitudinal slots 70 in the direction of arrow 111 in push the locking position which is reached when, on the one hand, the lug 60 abuts with its stop surface 113 somewhere, or the pins arranged in the slots 70 come to the end of the slot 70, or for example the cam surface 105 at the 45 ° position ( Reference number 192) located thumb of the cylinder 36 or on the cylinder peripheral surface 115.

The pivot lever lock is unlocked by bringing the thumb 92 or the thumb 192 of the cylinder 38 or 36 back towards the upward-pointing position during which rotational movement the thumb actuated in each case slides along the somewhat curved cam surface 100 or 105 and thereby moves the locking bar 46 against the direction of arrow 111 and against the force of the spring 56 into the unlocking position until the position shown in FIG. 18 is reached.

17 and 19, round openings 117 and 119 are shown, which are also in the side walls of the

Locking bar 46 are arranged and serve as a passage opening for fastening screws that are to be screwed into the bore 80 or 82. These bores 117 and 119 have the diameter of the head of the respective fastening screw for the cylinder lock and are arranged such that they are aligned in the unlocked position of the locking bar 46 for the respectively associated opening: the two openings 115 are then coaxial with the bores 80, and the openings 117 coaxial with the openings 82. This means that even if the locking bar 46 has already been installed and is fixed by pins pressed into the bores 72, 72 or 72 and can therefore no longer be removed (unless one is removed this

Pencils again), nevertheless an exchange of the

Cylinders are made. For this purpose, only the locking bar 46 must be brought into its unlocked position, whereby the bores 115 and 117, respectively, release the corresponding fastening screws for the cylinder located in the bores 80 and 82, whereupon the countersunk screws are unscrewed and then the cylinders from the in

Direction towards the front surface 78 open insertion spaces 74 or 76 can be pulled out.

It is clear that in a similar manner, as shown in FIGS. 12 and 13, yet another, third cylinder lock or even more than three cylinder locks can be connected in series in a similar manner, all of them with one the corresponding partition walls can act locking bar. This would make it possible to give a third authorized person access to a control cabinet, for example, with a third own key. However, this is not shown in more detail, since the vast majority of applications use two such cylinder locks.

It should be added that the displacement of the locking bar 46 by the thumbs 92 could also take place by these thumbs engaging in openings of a similar design to those formed by the openings 94, 96, with a corresponding arrangement of the locking bar 46 perpendicular to the direction of movement side edges to be arranged engaging edges for the thumb 92 or 192 could be created. The embodiment shown here is preferable for reasons of stability and because of the easier assembly.

The construction described so far is axially symmetrical (except for the arrangement of the mounting holes 80, 82), so that it can be used both for right-hand operation and for

Left-hand operation and accordingly also suitable for right-closing as well as for left-closing cylinders. This makes this construction universally applicable.

To the moving parts of the closure device (ie the cylinder with your thumb and the displaceable locking bar 46) against environmental influences, such as dust and

To protect moisture and thereby avoid malfunctions, the already mentioned cover cap 40 is provided, which is explained in different representations in FIGS. 21 to 24.

As can be seen from FIGS. 17 to 20, the

Locking bar ultimately an elongated box, whose a narrow side, here the narrow side pointing to the free end of the pivoting lever, the contact edge or contact nose 60 for engaging behind a fixed part of the recess or the door leaf rear surface, as already explained. Of course, it would also be conceivable to arrange a corresponding locking lug either on the left or right, or on the other narrow side, but the embodiment chosen here is particularly advantageous because the greatest possible distance from the lug to the pivot axis 26 of the lever means that the lug acts on the lug Force on unauthorized

Attempts to operate are the smallest.

Another advantage of this arrangement is that it can be achieved in a simple manner that a corresponding breakthrough edge 121 of the trough 18 shown in FIG. 8 acts as a cam when the pivoting lever is pivoted in through the inclined surface 119 at the front end of the locking bar 46 slides along the cam track 119 and thereby (regardless of the position of the thumbs 92 or 192) presses the locking bar 46 against the arrow 111 into the unlocked position until finally this cam track 119 ends at the break-off edge 123, whereupon the spring 56 locks the locking bar 46 in can press their closed position unless the thumbs 92 and 192 prevent this. That means that as a result of this

Cam surface 119 with thumbs 92, 192 in the locked position (i.e. that these thumbs are at least 45 ° from the upward unlocked position shown in FIG. 18) allows pivoting of the pivot lever lock and subsequent automatic locking.

The trough 18 into which the pivot lever base 54 described so far with the locking bar 46 can be pivoted is no longer symmetrical.

As the cross-sectional representation of FIG. 11 shows, the Trough a type of tub shape, with tub walls 127, which appropriately accommodates the correspondingly spherical handle shape according to FIG. 15, in particular the wall shape thereof in area 129. The trough forms a perforated bottom 131 around which

To be able to have the rear ends of the cylinders and the parts of the pivot lever base 54 projecting approximately as far. For a thumb excluded by 45 °, see

18, 92, in spite of the narrowness of the entire arrangement, the

Breakthrough 131 still on one side breakthrough extensions 133, 135, such breakthrough extensions being provided here only on one side, because it is always possible to arrange the cylinders so that they have theirs on only one side

Exclude thumb. By means of the breakthrough extensions 133, 135 it is in turn possible to bring the swivel lever back into its swiveled-in position even with the thumbs of one or both cylinders 36 and 38 in the locked position, without first bringing the thumbs into the unlocking position in which Position they would not emerge from the outer walls of the locking bar 46.

The special conical shape of the breakthrough extensions or recesses 133. 135 have a dovetail shape.

The mounting of the pivot lever 22 in the area of the axes 24 and 26 should not be described in more detail here. In this context, reference is made to EP 0 261 266 A1, where various mounting options are shown, which are dependent on the type of closure which is caused by the Swivel lever to be driven.

It should only be hinted that, as already mentioned, the trough 18 with the extension 32 can be inserted axially centering through the corresponding opening 12 of a door leaf or the like 16, with a circumferential rear jump 139 for receiving an annular seal for sealing the trough against the door leaf, there are also two circular lugs 141 with associated blind hole 143 for receiving a thread-cutting nut, this nut, for example, connecting a gear box or the like to the trough 18 and simultaneously

the door leaf sheet is clamped between itself and the recess, as described in the European patent mentioned. Similarly, the encirclement of the opening 131 forms an extension 34 (again with a circumferential groove 239 for a sealing strip) and two extensions 241 for receiving fastening screws for a cover cap 40 which can be seen in different representations in FIGS. 21 to 24.

This cover cap on the one hand closes the opening 131 in the direction of the interior of the space to be closed

(for example, the interior of the control cabinet), on the other hand, this cap protects the movable parts of the pivoted lever when it is pivoted in against dirt and other influences which can occur in the interior of the control cabinet, for example arcing gases and the like.

The outer shape of the cap is only in that

Significance when it has to extend beyond the breakthrough extensions or depressions 133, 135, which is why the cap has the bulge 125 and the asymmetry caused thereby, similar to the asymmetry which is formed by the breakthrough extension 133, 135, the cap being mounted in this way in each case can that the bulge 125 faces the breakthrough extensions 133, 135. In addition, the cap should only be so large that it does not hinder the insertion of the pivoting lever with its moving components, just as little as the displacement of the locking bar 46. The cap has two injected holes 145 which are aligned with the blind holes 243 in the trough 18 and to

Inclusion each serve a self-tapping fastening screws in the blind holes 243. With their lower edge 147, the cap lies against the thin wall or door leaf 16, as can be seen in FIG. 1. The fastening screws 149 not only hold the cap 40 in place, but also the recess 18 in the door leaf.

In order to protect the front surfaces of the cylinders against dust and environmental influences, an additional one can be used

Cover cap 151 can be provided, which can be seen in FIGS. 25 to 27 in different representations. This

Cover cap can be fastened with an axial extension 153 located at one end, which can be fastened by an in the

Swivel lever base 54 located matching shaped hole 153 is inserted and then through a locking disc or

the like, which can be inserted into the depression region 155 from the other side.

Then this room 155 as well as the

Receiving space 109 for the spring 56 can be closed by a plate 157 by means of a again self-tapping screw 159, see FIG. 13, for which purpose the

Pivot lever base 54 may in turn have a projection 161 with a blind hole 163.

The cap 151 may have depressions 163 for receiving slightly projecting cylinders if such projecting cylinders are used. Furthermore, this cap has a depression 339 running around the pin 153 for receiving a seal. A breakthrough 165 can also be seen, which in connection with a corresponding breakthrough 167, to which it is aligned when axially aligned with the pivoting lever, enables a sealing wire to be pulled through, so as to be able to seal the cover cap in its position covering the cylinders.

Furthermore, projections 169 can be seen, which protrude somewhat and the pivot lever on its top grasp slightly and hold the cover in its covering position.

To release the cylinders, this cover 151 must therefore be raised slightly so that the projections 169 are pushed over the front surface 78 and the part 151 is pivoted about its axis 153 until the two cylinders of the pivot lever are released.
