Abstract

A swivelling lever control that can be locked after being swivelled inwards and for closing switchboard cabinet doors or the like has a trough (18) set on the outer surface of the door or the like, in which the driving device for the closure, such as gear drive, lever drive or locking shaft (20), is arranged. An actuating lever (28) is articulated to the driving device so as to swivel out of the trough (18) about an axis (30) parallel to the supporting surface of the trough. A hook device (58) on the actuating lever (28) engages a back engagement surface of the trough (18) when the actuating lever (28) is swivelled in, thus retaining the actuating lever after it has been swivelled into the trough. According to the invention, the actuating lever projects at its free end beyond the trough and/or bears an unlocking means with an actuating surface for the hook device that can be actuated by a pressure acting away from the outer surface of the door or the like.

Description

The invention relates to a swivel lever actuated in swiveled state for the closure of cabinet doors or the like., With a recess on the outer surface of the door or the like. In which the drive means for the closure, such as gear drive, lever drive or shutter shaft is arranged, at which Drive device, an actuating lever is pivotally pivoted about an axis parallel to the support surface of the trough from the trough, wherein the actuating lever, a hook means is provided which engages a Hintergrifffläche the trough with pivoted-in operating lever and thereby holds the operating lever in the pivoted position, and wherein the actuating lever protrudes at its free end over the trough and the actuating lever carries an unlocking with an actuating surface for the hook device.

Such a verbarer pivotable lever operation is already known from US 5 620 213 (Ellis).

In this known arrangement, the actuating lever in its pivoted-in position in the trough forms an upper, directed away from the door surface, which projects in the direction of the free end and thereby further protrudes into the front of the door room.

Further, reference is made to US 5,467,623 (Takigen). A disadvantage of this known arrangement is that the actuating surface must always be pressed in the direction of the door leaf to release the lock by the hook and to swing out the hand lever from its pivoted position, d. h. That the unlocking (pressing) in conflict with the pivoting out, so pulling the operating lever. There is also no possibility to arrange the finger lever such that the printing direction coincides with its operation with the opening direction of the actuating lever. In this arrangement, one is therefore forced to assist the pivoting of the actuating lever by a strong compression spring, while the operation of the finger lever must be against the force of a spring with relatively little resistance, so that the two spring effects do not interfere with each other.

The object of the invention is to develop the known arrangement to the effect; that the actuating lever protrudes as little as possible in the front of the door room.

Furthermore, the actuating surface of the unlocking should be able to be operated so that the pivoting of the actuating lever is not hindered by the unlocking.

In US 5,467,623, the operating lever can be additionally locked by a cylinder lock. This should still be possible. Such additional locking is advantageous if the pivot lever lock strong May be exposed to vibration. Such strong vibrations are possible for example by seismic action, or in the arrangement of the closure devices on cabinets, which are arranged on machines that vibrate strongly during operation, as it may be the case for example in cranes.

Furthermore, the arrangement should be designed such that a padlock can be used.

The problem is solved by the characterizing features of claim 1.

Further embodiments are contained in the subclaims 2 to 9.

The invention will be explained in more detail with reference to constructions and exemplary embodiments, which are illustrated in the drawings, wherein embodiments according to the invention are shown in FIGS Figs. 24 to 31 are shown, while the preceding figures are illustrative only.

In Fig. 1 is a side view of a pivot lever actuator 10 for the closure 12 of a cabinet door 14, housing wall, sheet-metal box cover or the like. Recognize, with a on the outer surface 16 of the cabinet door 14 or the like. Placed trough 18, in which a closure shaft 20 is arranged is that in not shown manner, for example, carries a cam 22 and here also along the door leaf extending ribbon locking bars 24 or, as shown in FIG. 3, round rods 26 drives. In this connection reference should be made to European patents 0 054 225, 0 261 266 and 0 261 267 for further details.

At the free, directed away from the cam end of this closure shaft 20, an actuating lever 28 is hinged out about a transverse to the axis of the shaft 20 extending axis 30 of the trough 18 out. In the swung-out state, as can be seen dashed in Fig. 26, the shaft 20 can be rotated about its axis 32 with the actuating lever 28, for example, a cam follower 22 behind the door frame 36, see Fig. 2, a control cabinet, here not shown, to pivot and thereby close the door. Alternatively or additionally, as shown in FIG. 1 by flat ribbon rods 24, which can be moved up and down, achieved a door closure position, wherein a Auflaufrad 34 runs onto the edge of a control cabinet housing 26 shown in FIG. 1 and the door leaf 14, on which the locking rod 24 is guided by means of rod guides 38, holds. In the constructions shown in Figs. 1 and 3, the locking bars 24 are in the locked position, in which the operating lever 28 points downwards, as can also be seen in Fig. 26. In this position, the actuating lever 28 can be pivoted into the trough 18, in which position the actuating lever 28 is substantially surrounded by the trough edges. The facilities described below are now intended to hold the operating lever in this pivoted position, in which the operating lever 28 is prevented from being rotated out of its trough-oriented position as a result of this encircling by the trough edges. Opening the door is therefore not possible in this position.

When the operating lever 28 is in its vertical downward position, its own gravity and friction may be sufficient to keep it in that position. For shaking movements, as for example in Crane systems may occur, however, there is a risk that the actuating lever 28 moves away from its pivoted position back and enters the position shown in Fig. 26 in dashed lines pivoted position. In this position, a rotation about the axis 32 can then take place by further shaking movement, whereby u. U. the shutter 12 opens and thus the interior of a control cabinet is exposed in an undesirable manner. It is also possible that an unauthorized person swings the operating lever 28 and brings by rotation about the axis 32, the door lock from its closed position to an open position, thereby obtaining the opportunity to open the door 14 of a control cabinet.

To prevent this, one can provide the hand lever 28 of FIG. 6 with a projection 39 at its free end, into which a cylinder lock 41 can be received, see FIG. 5. The thumb of the corresponding cylinder can be mounted so that it Excluded state with pivoted lever 28 applies to a rear surface 43 of the door panel 14 and thereby prevents unwanted pivoting of the hand lever 28 from its pivoted position out.

Alternatively, such a thumb can also lie behind a contact surface formed by a screwed-on box 45. However, it is not necessarily visible whether the cylinder 49 is excluded, that is, the control of the closure state is difficult. In order to provide an additional or alternative safeguard, a lug 118 carried by the trough 118 is provided, see Figs. 3 and 22, at the free end of which an eyelet 42 is disposed. When pivoted lever 128, this eyelet passes through an opening 44 of this hand lever and allows the passing through the bracket 46 of a padlock 48, which also prevents pivoting of the hand lever 128 from its pivoted position.

The backup by means of a padlock 48 has the great advantage that z. B. at certain times and occasions an individual, a specific person belonging padlock 48 can be used to give this person the opportunity to secure a door against unauthorized opening. Only this person can then open the padlock again with the help of an associated key, unhook and then open the corresponding door lock by unfolding and then turning the operating lever.

In order to achieve a detention of the actuating lever in the pivoted position, a hook means 58 is provided on the pivot lever 128 which engages a Hintergrifffläche 60 of the trough 18 with pivoted-lever 128 and thereby holds the operating lever 128 in the pivoted position. The hook 58, which is pivotally supported here about an axis formed by the actuating lever 128 62, has a first actuating surface 64 which projects beyond the end of the actuating lever 128 and is directed so that an operator under the lever 66 on this surface 64th of the lever 66, corresponding to an opening movement of the hand lever 128 to swing the hook 58 out of its locked position (as viewed in counterclockwise directions in FIGS. 5, 6, 8 and 9) which pull direction not only pivots the hook 58 out of its locked position; as shown in Fig. 9, but also after releasing the hook then pulls the operating lever 128 from its pivoted position. This operation procedure is intuitively inputted to an operator and therefore constitutes a particularly favorable embodiment of this hook device 51.

By means of a second actuating surface 70 provided here, which protrudes beyond the plane 52 of the actuating lever 28, but can also with a pressure movement in the direction of the actuating lever surface 52 of the hook 58 from his Locking position are swung out. The further lever arm forming this actuating surface 70 also carries on its rear side a recess 72 into which one end of a compression spring 68 is received, while the other end of the compression spring 68 is retained in a recess 74 formed inside the operating lever 128.

The actuating lever 128 may be provided in the region of its axis 30 with a further spring means, as in the prior art, to bring it out automatically when needed from its pivoted position. In this case, when the hooking means 58 is pressed on the operating surface 70, this hook comes free and the spring action pushes the operating lever out of its pivoted position unless it is held by the cylinder lock 41 or a hung padlock 48. Such a construction is shown in Fig. 21 in a plan view, Fig. 22 in a longitudinal sectional view and Fig. 23 in a rear view. These FIGS. 21, 22 and 23 also show a further possibility of locking. It is an approximately centered on the operating lever 128 arranged head bolt 76, which may be rotatably mounted in a recessed opening 78 of the actuating lever 128. The free end of the bolt 76 has a transverse pin 80 which can be received in a specific position of the head pin 76 when pivoting the operating lever 128 into an opening 82 of the trough 118. The area of the trough 118 which forms this opening 82 protrudes somewhat, so that rear grip surfaces 84 form, behind which the ends of the pin 80 lie, when the head pin 76 is now rotated by 90 °. It is thus a kind of bayonet lock, which makes it possible to lock the operating lever 128 in its pivoted position by means of this head bolt 76 also. A torsion spring provides automatic locking, and with a screwdriver (or socket wrench with other head shape) is opened against spring pressure. The turning of the head bolt 76 in and out of the locking position can be done with the aid of a tool, here by means of a screwdriver, not shown, which is inserted into a slot 86 of the head pin 76. But this task can be solved by a bolt or a pivotable tongue when it can be moved by an eccentric or torsionally rigid connection against spring force, possibly with freewheel.

The trough has, according to FIG. 1 and FIG. 3, a projection 88 extending through the door leaf 16, which is part of a closure shaft bearing, and which, for example, according to FIG. 1, is in communication with a closure box, which between itself and the trough 18 Door leaf 16 pinched and thereby holds the trough. The opening provided for this purpose in the door leaf is rectangular in this case, similar to that required by the construction according to the already mentioned European patent specification 0 261 267.

According to Fig. 3, a construction is provided in which instead of a lock case, a disc 13 is provided, on the one hand, the Vorreiberzunge 22, on the other approaches for the articulation of the round rods 26 go out.

In the (here two-part) lock case 11, a drive pin 24 driving pinion is mounted, which in turn is driven by the drive shaft 22 to which the actuating lever 28 is pivotally articulated, see Fig. 6. The attachment of the lock box 11 takes place on the trough 18 according to the construction shown here by means of screws 15 which pass freely through openings 19 formed by the lock box 11 and are then screwed into slightly narrower holes 17 formed by the recess 18. The well material will normally be plastic, so that it is possible to cut into the bore 17 with correspondingly shaped fastening screws, so that the prior introduction of threaded holes is not required.

When tightening the lock case 11 on the trough 18 of the edge region of the opening is trapped in the door leaf, as shown in FIG. 5 reveals. Similarly, at the other end of the trough by means of a lid 25 of the through Door leaf 14 extending through reaching 87 of the trough 18, which projection 87 also forms the aforementioned Hintergrifffläche 16 for the hook means 58. Also, apertures 19 are provided in the cover, can be inserted through the mounting screws, which then dig into holes 17 of the trough 18 and thereby set the lid on the trough 18. In this case, in turn, the edge region of the opening in the door leaf 14 between the edge or end face 27 of the lid 25 on the one hand and the shoulder 29 of the flange-like projecting trough 18 is clamped and thereby held the overall arrangement.

It should also be mentioned that the head of the fastening screw 15, not shown in Fig. 9, within a recess 31 which is formed by the lid 25 and the lock box 11, is receivable and in the region of this recess 31 also annular projections 33 can be seen on which hangs the bearing surface of the screw head and forms a seal.

While Fig. 8 shows the hook means 58 in the locked state, Fig. 9 shows the arrangement again after an operator has grasped under the operating surface 64 and thereby pivoted the hook 58 counterclockwise. As a result, the hook is released from the Hintergrifffläche 60 of the trough 18 and the operating lever 28 can therefore be swung up out of the trough. If the operator now releases the actuating device, the compression spring 68 presses against the spring receiver 72 of the hook device 58 and rotates it about the axis 62 in the direction of the clockwise movement until the surface 47 of the hook device 58 abuts the stop surface 49 of the depression 18.

In the reverse movement, ie when pushing in the hand lever 28 into the trough an inclined surface 51 of the hook end 53 meets the inclined surface 55 of the trough 18, whereby the hook means 58 is again pivoted counterclockwise about the axis 62 until the hook end 58 in the Rear grip position 60 passes and the hook moves in the clockwise direction and locked.

He has then reached the position shown in Fig. 8 again.

Fig. 7 shows how the actuating lever 28 at its free end pivotally about the axis 62 pivotable hook means 58 U-shaped and thereby enables a particularly secure storage.

The construction shown here requires that when pressing the operating lever 28 in the trough, the hook means 58 can move freely, so not for example by the operating lever 28 is pressed that is pressed onto the surface 55 of the hook means 58. In this case, it could happen that the hook with its inclined surface 51 does not get past the inclined surface 55 of the trough 18, because it is not allowed to avoid the counterclockwise direction by the pressure on the surface 55.

On the other hand, an operator tends to seize the operating lever 28 at its free end and push it into the trough. The construction shown in FIGS. 10 to 14 takes greater account of this fact.

The end 157 of the hand lever 28 is fixedly connected to the hand lever 28 as shown in FIGS. 10 to 14, so does not affect the movement of the hook means 158. It is therefore possible to grasp the hand lever at its free end 154 and push it into the trough in this construction, without thereby the sliding movement of the inclined surfaces 151 of the hook end 153 along the inclined surface 155 of the trough 18 of acting on the hook means 158 compressive forces is hindered. On the contrary, should the thumb of the operator slip over the surface of the end 157 of the hand lever 128 toward the pressure surface 170, the escape would even assist.

However, it is possible to make a release here in a simple manner, although in this embodiment, a door handle surface facing the actuating surface for the hook means 158 is not available. Instead, namely, a traction surface 164 is present, which by pressing the surface 170 by means of z. B. the thumb of the operator at the same time the operating lever 128 can pull out of its pivoted position, namely z. B. with the index finger surface. Here is thus achieved by the close spatial relationship between the traction surface 164 and the pressure surface 170, the effect of the invention, both with a handle to unlock the pivot lever 128 and pull out of its pivoted position, which does not allow the prior art.

Yet another and even less expensive construction is shown in Figs. 15-19, where the hook means 258 is designed to provide a free-wheeling action. The hook-end 253 and hook pivot axis 262 are each arranged at approximately the same position as in the construction of FIG. 8. The compression spring 268 is housed in a bag formed by the hook means in which it is supported at one end, while the other end of the Compression spring 268 is supported on a bearing surface formed by the trough 18. The lever 266 forming the pressure surface 170 forms a rear land 263 which, when pulled up by pressure on the surface 264 of the lever 266, abuts the surface 267 of the hook means 258 and pivots it about the shaft 262 counterclockwise.

Now, if the pivoted lever 28 is pivoted back into the trough 18, the inclined surface 251 of the hook end 253 can slide along the inclined surface 260 of the trough 18 while pivoting the hook 253 counterclockwise, without causing the lever 266 would have to pivot upwards. Rather, at this moment the surface 267 lifts off from the web 263, as shown in FIG. 19 reveals, so that a pressure on the surface 170 for closing the hand lever does not interfere here appears.

The constructions described in FIGS. 1 to 19 are installed in a door leaf which has two openings which are essentially rectangular and preferably symmetrical with respect to the center of the door. In the construction according to FIGS. 20 to 23, the depression 118 shown there has a projection 188 which has a circular outer cross section and an external thread, possibly with flats 187, in order to be able to insert the projection 188 into circular apertures provided with corresponding constrictions in sheet metal cabinet doors. On the projection 188, a fastening screw (union nut) can then be placed and the door leaf between this nut and the trough support surface 118 are clamped, as shown in Fig. 25.

Figs. 20 to 23 are an example of how the assembly can be connected to a padlock lockable rocker arm. The eyelet 42 provided for the padlock 48 is carried by a lug 40, which may be integral with the trough 108, but may also be configured such that this lug 40 may be designed for reasons of strength (for example, if the trough is made of plastic) is a separate component made of metal, which has a base plate 92. This base plate can be inserted from behind into a corresponding recess 94 of the trough 118, such that their base surface is flush with the base of the trough 118, as shown in FIG. 22 reveals. The edges of the foot plate are then held by the projections 196 of the trough 118. Alternatively, the lug 40 could also be injected into the material of the well 128.

The padlock 48 shown in Fig. 22 is obliquely outward, whereby the lock is easily accessible.

The embodiments shown in Figs. 24 to 26 and 27, respectively, represent the invention. These embodiments of the invention avoid disturbing protrusion of the lock 48.

The main difference to the construction of Figs. 20-23 is that the lug 140 has been pushed to the lower end of the trough 218, thereby giving the padlock 48 room to hang freely down. The lower end 65 of the operating lever 228 in the figures is slightly bent away from the door leaf 14 and the trough and thereby facilitates the extraction of the operating lever 228 from its pivoted position, with simultaneous operation of the hook means 158, which is possible with one hand. Of course, this withdrawal can only be made when the padlock 48 is removed from the eyelet 142.

The eyelet 142 is here designed so that it is formed by a projection 140 with a foot 192, the shape of which may be designed similar to the projection 188 in which the closure shaft 32 is mounted, so with an external thread and possibly two or four flats on which external thread a fastening nut 190 can be screwed, which clamps the door leaf 14 between itself and the trough 218. The trough 218 is in turn held in place by a ring 193 formed by the foot 192 and received in a corresponding recess 194 in the interior of the trough.

The advantage of the construction according to the invention shown in Figs. 24 and 25 is on the one hand the greater stability by attachment by means of two over the support surface of the trough projecting and provided with a union nut 90 or 190 projections 188, 192, and on the other hand, the less prominent padlock 48th

Another advantage is the usability as both a left and right closure, if the openings for the projections are arranged symmetrically to the center of the door. Similar advantages also apply to the embodiments in which two rectangular openings are provided.

It should be added that by means of sealing rings 95 between the door leaf outer surface and trough in the region of the projections 188 and 192, the inner region of the cabinet can be sealed against its outer region, if the shaft 32, on the one hand, the lever operation 228 is articulated at 30, on the other the deflector 22 may be fixed by means of screw 21, is equipped with an O-ring seal 23.

Fig. 27 shows a somewhat modified, but also according to the invention embodiment, in which instead of attachment with a nut 90 of the projection 240 similar to the projection 40 of FIG. 22 is supported by the trough 318. The trough 318 itself is held at the upper end similar to Fig. 26 by a nut 90, but at its lower end by a bolt 91 which is arranged with its bolt head on the back of the door leaf 14, and with its threaded portion in a corresponding Tapped hole 89 within the material of the trough 318 extends.

While in the embodiments of Figs. 24 to 27, the eyelet of the projection 140 protrudes by a dimension a over the surface of the operating lever 228, in the now described embodiment, see Figs. 28 to 31, this is no longer the case. The projection 340 is kept even shorter, thereby allowing the operating lever 428 as well as the trough 418 for the padlock 48 to be recessed even more than in the previous embodiments. Additional space is created in that the front portion 465 of the operating lever 428 extends into a recess 497 of the trough 418, thereby retaining sufficient material thickness. The upper portion of the eyelet 340 thus no longer projects beyond the upper surface of the operating lever 428.

The padlock 48 remains below the alignment line of the Forderfläche the swiveled actuating lever, so that there is an extremely flat embodiment.

This extremely flat version is particularly well suited to be placed in escape routes because no protruding parts obstruct people who are fleeing. Again, the end of the hand lever 428 jumps so far that both the actuating surface of the hook means 458 can be operated with a handle, and the actuating lever can be pulled out of its trough.

The arrangement according to the invention can also be used with such closures, which are already actuated when pivoting out of the actuating lever from the trough, so do not require subsequent rotation of the pivot lever.

Claims (9)

1. A pivot lever actuation which can be secured in the pivoted-in state, for the locking of control cabinet doors or the like, with a trough (218, 318, 418) able to be placed on the outer surface of the door or the like, in which the activating mechanism for the locking, such as a gear wheel activation, lever activation or locking shaft (20) is arranged, at which activating mechanism an actuating lever (228, 428) is linked around an axle (30), running parallel to the bearing surface of the trough, in such a manner as to be able to be pivoted out of the trough (218, 318, 418), whereby, at the actuating lever (228, 428) a hook mechanism (158, 258, 458) is provided, which, when the actuating lever (228, 428) is pivoted in, engages with a rear gripping surface (160) of the trough (218, 318, 418) and thereby holds the actuating lever in the pivoted-in position, and whereby the actuating lever, at its free end, protrudes over the trough and the actuating lever carries a releasing mechanism with an actuating surface for the hook mechanism, characterised in that the upper surface, directed away from the door, of the actuating lever (228, 428) which has pivoted into the trough, near its free end, returns back in the direction of the door, that a lug (140, 240, 340) comes out of the trough, at the free end of which a loop (142) is arranged such that, when the actuating lever (228, 428) has pivoted into the trough (218, 318, 418), the lug (140, 240, 340) reaches through an aperture (144, 344) in the actuating lever and a padlock (48) which is hung through the loop prevents the actuating lever from pivoting out, that the actuating lever (228, 428) forms a returning surface in the area of the aperture, which returning surface receives the clip (46) which penetrates through the loop (142) of the padlock (48), in a fitting manner, that the trough (218, 318, 418), in the area of the clip (46), also has an indentation which receives the clip in a fitting manner.
2. The pivot lever actuation according to Claim 1, characterised in that the releasing movement of the hook mechanism occurs against spring force (68).
3. The pivot lever actuation according to Claim 1, characterised in that, between the hook mechanism and the lever arrangement which actuates the hook mechanism, a freewheel mechanism is provided.
4. The pivot lever actuation according to one of Claims 1 to 2, characterised in that the actuating lever is able to be pivoted into the trough against spring force.
5. The pivot lever actuation according to one of Claims 1 to 4, characterised in that the actuating lever also has a locking mechanism (76) able to be actuated by a tool.
6. The pivot lever actuation according to one of Claims 1 to 5, characterised in that the trough (18) has two protrusions which reach through the door leaf (14) or the like, whereby one of the protrusions forms a bearing for the locking shaft, whilst the other protrusion (39) includes the rear gripping surface for the hook mechanism (58).
7. The pivot lever actuation according to Claims 1 to 6, characterised in that the protrusions (188) form peripheral threads, onto which mounting nuts (90, 190) are able to be screwed, which clamp the door leaf or the like between themselves and the trough (438).
8. The pivot lever actuation according to one of Claims 1 to 7, characterised in that the protrusions have a rectangular cross-section and that cap mechanisms or lock socket mechanisms (11) are able to be screwed onto them, which clamp the door leaf (14) between themselves and the trough (18).
9. The pivot lever actuation according to one of Claims 1 to 8, characterised in that it is used to actuate a flat rod lock, a rounded rod lock and/or a sash lock.
