Dr-eristarigenve:

The invention relates to a pivoting rod lock according to the preamble of claim 1.

A special Brehstany^iiyer lock is known from DE 83 03 077.8 TTl, locks ^of the type described above are used in particular for the bodies of trucks or containers in order to be able to close ^{the bodies} tightly and positively against the frame of the container.

On the one hand, these espagnolette locks have the advantage of being able to use the hand lever as a "lever" to open or close the espagnolette. On the other hand, it is also necessary to be able to arrange the handle parallel to the espagnolette in order to open the door more conveniently and easily after the espagnolette lock has actually been opened.

f to be able to wind up sooner. In this winding position,

p Therefore, the hand lever is usually parallel to the

Turning rod, whereby it is connected via its turning rod end and

&ngr; a bearing firmly welded to the rotating rod, for example,

is conclusively connected with it.

This latter bearing arrangement of the hand lever in the winding position is realized in the aforementioned, known rotary *' rod lock via a pivot axis provided in the bearing and an elongated hole in the hand lever.

Since the various i -.< jsen and ver-

Since the containers and truck bodies mentioned above are very often used in transit traffic and therefore have to comply with customs regulations and customs security requirements, the well-known espagnolette lock has proven to be too unsafe for transit traffic. This is because the locking of the handle in the case of transit/final customs sealing can still be manipulated in the locking position.

Taking these aspects into account, the invention is therefore based on the task of designing an aforementioned espagnolette lock that is both safe for traffic and customs, whereby the leverage effect when turning the espagnolette or the arrangement of the hand lever should be provided as a winding aid.

This object is achieved according to the invention by the features of the characterizing part of claim 1.

A key idea of the invention can be seen in the interaction of the hand lever with the bearing attached to the rotary rod in such a way that a longitudinal displacement is possible via a bolt-slot connection of the hand lever in the bearing. This longitudinal displacement is structurally linked to a locking bolt, the fastening areas or flanges of which lie in the longitudinal direction of the lever and are completely covered by the lever in the locked position. This locking bolt has a nose oriented towards the rotary rod. An opposite orientation of the nose of the locking bolt is also possible. However, the design of the nose as shown in Fig. 2 will be discussed below.

The closure of this locking ^ring is activated when the con! liner is closed by a locking mechanism in the upper part of the hinge.

'!fjhfv v/pqhpv/f'q t . As a result, the nose of the locking bolt overlaps a surface of the handle, so that a rotary movement to open the rotary rod is blocked. At the same time, in this position, a safety device attached to the lever is swung in against the locking bolt, which also prevents a longitudinal movement of the hand lever.

To prevent the handle from being opened by unauthorized persons, the swiveled-in safety device is secured with the locking bolt, e.g. using a padlock, via aligned openings.

From a customs point of view, the hand lever, which is bent from a flat iron, for example, has two cheeks protruding from its sides in the locking area. The inner surfaces of these cheeks limit the recess in which the locking bolt is received. The cheeks are expediently equipped with openings roughly parallel to the rotating rod. Furthermore, the locking bolt itself and its main body are also provided with openings, e.g. a rectangular contour, which are aligned with the openings in the cheeks when locked. In this way, it is possible to guide a customs band through the cheeks of the hand lever and the locking bolt.

Taking into account the complete coverage of the fastening flanges of the locking bar by the locking part of the hand lever in the closed state as well as the securing of the hand lever against longitudinal displacement and the support between the cheeks of the hand lever and the locking bar, the invention offers a customs-safe rotary bar lock while maintaining security and simple handling.

Further advantageous embodiments of the invention are set out in the subclaims and the description of the exemplary embodiment shown in Scheme 1 .

The invention is described in more detail below using a schematic embodiment. Shown are:

Fig. 1 shows a rotating bar lock according to the invention in the locked state with an attached padlock and a customs band, essentially in a perspective view;

Fig. 2 shows the locking bolt, which is largely covered by the hand lever in Fig. 1, in the same arrangement as in Fig. 1;

Fig. 9 a safety device for the hand lever to block a longitudinal displacement of the same relative to the locking bolt, approximately in the position shown in Fig. 1.

&Egr; Ule perspective view after tig. &khgr; shows &bgr;&khgr;&igr;&eegr;&pgr; Ol eh rod closure 1, which essentially has the vertical rotating rod 2, to which a bearing 3 is welded, projecting approximately perpendicularly from it. In the bearing 3

the end of a hand lever 5, >; which can be bent from a flat iron, for example, is guided. ^r This hand lever 5 has a bearing area 9 in the area of the rotating rod 2, a locking area 8 in the middle part and the actual handle area 7 in the left area.

The closure area has two cheeks 15 which protrude approximately vertically and which are provided with a vertical opening 31 (Fig.

3). Furthermore, in the left area of the ■ closure area, e.g. by means of a rivet bolt 23, a

SichöJTuriy 14 rotatably mounted around the rivet bolt.

In Fig. 2, the locking bolt 10 is also shown in perspective. The locking bolt 10 essentially has a main body, which protrudes with a nose 11 in the direction of the rotary rod 2 from a plate with fastening areas 36 formed in the longitudinal direction of the hand lever 5. These fastening areas 36 are fixed, for example, with countersunk screws against the corresponding door of the container. In the example, an opening 30 is provided in the main body vertically, i.e. approximately parallel to the rotary rod 2, which penetrates the hollow main body downwards. Furthermore, a further opening 28 is present in the surface 38 lying against the lock 14.

In the perspective view according to Fig . 1, the hand lever 5 is positioned straight in the direction of the arrow so that a rigid connection is established between the bearing 3 and the rotary rod 2 in the direction of the arrow. In this position, the hand lever 5 is pushed forwards along the elongated hole 6 against the rotary rod, whereby a bolt 16, which is fixed in the J-shaped bearing part 3, guides the longitudinal displacement of the handle 5.

In Fig. 3, the shape of the hand lever 5 is particularly clear. For example, the bearing area 9 and the handle area

7 of the hand lever, while the locking area

8 has a contact surface that is cranked or curved in the direction of the container door and the plate of the locking bolt 10. The bending shape, roughly in the form of an elongated "S", between the locking and handle area thus allows the handle area 7 to be easily grasped and gripped behind at all times, while the locking area lies flush against the plate of the locking bolt 10. This support, which ensures that the fastening areas 36 are covered, means that the locking bolt cannot be manipulated by unauthorized persons in the locked position.

In the locking area 8, the hand lever 5 has a rectangular recess 12 (Fig. 4) between the cheeks 15. Furthermore, a safety device 14 (Fig. 9) is pivotably attached to the hand lever, preferably via a ^rivet bolt, through an opening 25 to the hand lever. In Fig. 3 (open position), this safety device 14 is rotated upwards from the locking position (Fig. 1) until its upper surface edge comes into contact with the bend in the handle area 7.

In the position shown in Fig. 3, the hand lever 5 is moved in the direction =": ?. the locking bolt 10, whereby the recess 12 of the maximum length of the central body is

finally corresponds to the nose 11 of the locking bolt. The essential part of the central body with the opening and the nose 11 thus passes through the recess 12 of the hand lever 5. A longitudinal movement of the hand lever 5 is then carried out in the direction of the handle area 7, i.e. away from the rotary rod 2, so that the nose with its undercut engages over the flat iron of the lever at the recess 12 in the direction of the rotary rod 2. The safety device 14 is now rotated from the position shown in Fig. 3 in the direction of the recess or the locking bolt 10, whereby the surface having the opening 27 comes to rest approximately against the rear surface 39 of the main body of the locking bolt 10.

After inserting a padlock 29 through the openings 28 and 27 and attaching a customs band through the openings 31 and 30, the customs-secure locking position of the espagnolette lock shown in Fig. 1 is achieved.

In this latter position, the nose 11 engages the outside 13 of the hand lever, while the hand lever 5 '

even in the elongated hole it comes into contact with the bolt 16 in the bearing.

However, in order to achieve an optimal winding position, j

the hand lever can be opened as shown in Fig. 3 &igr;

is brought into a position which is shown schematically in Fig. 6. The end of the hand lever 5 on the rotating rod side is designed as a tapered engagement end 21, whereby this approximately trapezoidal taper starts at the end of the slot 6. Due to the downwardly open bearing, it is therefore possible to pivot the hand lever 5 in the direction shown in Fig. 3, i.e. to pivot the hand lever 5 in the direction shown in Fig. 3, i.e. to pivot the hand lever 2 out of the way.

th upward movement of the hand lever 5 into the opening of the recess 34. The U-shaped bearing and the engagement of the engagement end 21 with the recess 34 result in a positively locking pull-up position, which facilitates a fixed, safe opening of the container door.

As shown in Fig. 7 and 8, the bearing 3 is essentially U-shaped, the distance between the legs corresponding approximately to the thickness of the flat iron of the hand lever and the height of the bearing 3 is also essentially adapted to the width of the hand lever.

The safety device 14 according to Fig. 9 is dimensioned in its distance from the hole axis to the surface 38 such that after inserting this safety device 14, as shown in Fig. 1, a longitudinal displacement of the hand lever 5 is impossible. On the other hand, the inserted safety device 14 is locked via the opening 27, e.g. by means of a padlock 29, in relation to the locking bolt 10.

The espagnolette lock 1 according to the invention therefore represents in a simple manner a non-manipulable, customs-proof lock for box bodies or containers.
