Every tubing section has a plastic insert for mutual alignment of a lock bracket and a lock body.

Description

The present invention relates to a locking arrangement for locking a door to a counterpart. The door may be, for example, a hinged door or a sliding door. The said counterpart may for example also be formed by a hinged door or a sliding door, or by a door frame or a building wall.

In particular, such a locking arrangement serves as a retrofittable additional securing means for a container having a first door and a second door. A container is understood to mean a mobile container which serves, for example, for the transport or storage of objects and, in particular, is designed as a steel construction. To protect against unauthorized opening of the container, the door wings are provided with locking arrangements, which are either already provided in the production or can also be attached later. It is desirable that such locking arrangements provide the most reliable protection against forcible opening.

So is out of the WO 03/054331 a locking arrangement for a container is known which comprises a sleeve mounted on the inside of a door. The sleeve partially takes on a bar, at its free end an eyebolt is attached. In the locking position, the eyebolt extends through an opening provided on the other door opening, so that the eye of the ring bolt located on the outside of the other door leaf. The door wings can be secured by a padlock guided through the eye, which is covered by a box-shaped protective housing. This locking arrangement provides effective protection against burglary, but is relatively complex both in their manufacture and in their installation and therefore expensive.

It is therefore the object of the present invention to provide a locking arrangement of the type mentioned, which is simple in their manufacture and in their construction and can be handled easily.

The object is achieved by the features of claim 1 and in particular by the fact that the locking assembly comprises a first pipe section and a second pipe section, wherein each of the two pipe sections has a securing web which traverses the interior of the respective pipe section transverse to the longitudinal axis of the pipe section, and wherein each of the two pipe sections has at least one fastening device for fastening the respective pipe section to the door or to the counterpart.

This locking arrangement is characterized in that within the pipe sections securing webs are fixed, which can be encompassed by a suitable securing means (eg U-lock) to connect the two pipe sections together and thereby secure the associated door against unauthorized opening. The securing webs are arranged protected in the interior of the pipe sections, whereby the access to these safety webs is made much more difficult at a break-in attempt.

The locking arrangement according to the invention is particularly suitable for walk-in building and storage containers in which valuable tools and machines are often stored at unobserved locations that regularly become the target of theft. Since leverage tools are often used for this purpose, with which the locking arrangement is to be broken, access to the securing webs or said securing means is made difficult by the pipe sections, which experience has shown preferred as attack points for burglary tools. However, the locking arrangement is also suitable for any other pivoting about a vertical or horizontal axis door (including flaps) or for sliding doors (including sliding gates).

Another advantage of the locking arrangement according to the invention is that it can be retrofitted to doors and associated counterparts of various designs.

In the context of the invention, a pipe section is to be understood as meaning a hollow body which extends along a longitudinal axis and is closed on at least three circumferential sides. Preferably, the respective pipe section is integrally closed circumferentially. However, it is also possible that the respective pipe section is opened to the associated door or to the associated counterpart and formed, for example channel-shaped. In this case, a peripheral region of the relevant pipe section is thus formed by a part of the door or its counterpart, to which the pipe section is attached. The two longitudinal end faces of the respective tube section are open to allow insertion of the securing means or parts thereof.

According to an advantageous embodiment, in the position of use of the locking arrangement, the two tube sections are arranged longitudinally adjacent to each other, i. the pipe sections are arranged one behind the other with respect to their respective longitudinal axis. In particular, they can be aligned coaxially with one another.

Preferably, the securing webs of the two pipe sections are arranged parallel to each other in the position of use of the locking arrangement.

It is advantageous if the securing webs are arranged at a distance from the two end sides of the respective pipe section. As a result, an improved protection of the securing webs is achieved.

According to a preferred embodiment of the invention, the locking arrangement further comprises as a securing means a U-lock, which has a lock body and a lockable on the lock body or detachable from the lock body lock strap, wherein in the position of use of the locking arrangement of the lock body secured to the lock hanger the securing webs of the two pipe sections surrounds and the U-lock is surrounded by the two pipe sections. Such a padlock is a particularly suitable securing means for connecting the two pipe sections. By embracing the two securing webs the associated door (eg first door) and the associated counterpart (eg second door) are fixed in their relative position to each other, so that an opening is not possible is. The said padlock may in particular be a padlock or a long-handle lock.

Advantageously, at least one of the two pipe sections can have a plastic insert for mutually aligning the lock strap and the lock body when the lock strap is secured to the lock body. As a result, the insertion of the lock bracket and lock body in the pipe sections is much easier. In particular, it also simplifies the insertion of the ends of the lock bracket in the corresponding receptacles of the lock body, especially as the pipe sections complicate a visual inspection of the actual closing operation.

According to an advantageous embodiment, the respective fastening device is formed by a fastening bolt, a mounting hole, a mounting flange or a mounting plate. The fastening bolt is inserted through a corresponding hole in the associated door or the associated counterpart and can be screwed by an additional nut with the door leaf. If the fastening device is formed by a mounting hole, a screwing on the door or the counterpart can be done by means of a separate bolt. Finally allow a mounting flange or a mounting plate as a fastening means welding or screwing the locking assembly on the door or the counterpart.

Alternatively, each of the two pipe sections may have a bolt which forms the securing web within the respective pipe section and forms a fastening bolt for fastening the respective pipe section to the associated door or the associated counterpart outside the respective pipe section. Accordingly, such a bolt fulfills both the function of the securing web and the function of the fastening device. The bolt extends through a bore on the door or counterpart and is bolted to an associated nut.

Preferably, the securing webs are fastened by one end to the inner wall of the respective pipe section by friction welding, in particular by rotary friction welding. As a result, the relevant securing bar can be reliably connected to the associated tube section in a particularly simple manner.

It is possible that each of the two pipe sections has a spacer on the side facing the door or the counterpart. This has proven to be particularly advantageous if the outside of the door or the counterpart is not flat or is provided with additional locking elements, since the spacers undisturbed access to the open end faces of the pipe sections is ensured.

It has proven to be advantageous if the respective spacer is formed by a further pipe section or by a hollow or solid block of metal or plastic.

According to a preferred embodiment, the pipe sections have a substantially rectangular, trapezoidal, oval or round cross-section.

It is preferred if the pipe sections have different sized cross sections. In particular, this can be done to adapt to the different cross-sections of the lock body and the lock bracket, so that they are performed as free of play in the pipe sections.

Advantageously, in the position of use of the locking arrangement, the first pipe section partly covers the second pipe section. This prevents that a gap remains between the pipe sections through which, for example, a saw blade for sawing the lock strap could be performed. Furthermore, it is also made difficult to set between the pipe sections lever tools for breaking the locking assembly.

It is preferred if the end face of the first pipe section facing the second pipe section is bevelled with respect to a normal plane to the longitudinal axis of the first pipe section. This makes it easy to produce an overlap of the pipe sections, without the opening of the door is hindered or a more complex processing or design of the pipe sections to produce the overlap is required.

The invention also relates to a container with two door leaves and a locking arrangement of the type explained.

Further preferred embodiments are described in the subclaims.

Fig. 1 shows a locking assembly 10 according to the invention, which is attached to two only partially shown door wings 12, 14, for example, a (not shown) container. Both door leaves 12, 14 have on their outer sides 24 guide sleeves 16 in which pivot rods 18 for actuating not shown here locking elements for fixing the door leaf 12, 14 are mounted on the container. Both doors 12, 14 are reinforced in their end by arranged on its inner side 22 rectangular profiles 26. At the according to Fig. 1 right door leaf 14, a seal 20 is attached, which seals the gap between the two door leaves 12, 14.

On the outside 24 of the right door leaf 14, a right pipe section 28 is attached, wherein between the right pipe section 28 and the right door 14, a right spacer 30 is provided, whose thickness corresponds approximately to the diameter of the guide sleeve 16.

In a corresponding manner, a left pipe section 32 and a left spacer 34 are attached to the outside 24 of the left door leaf 12.

The diameter and the length of the left tube section 32 are smaller than the diameter or the length of the right tube section 28. Both tube sections 28, 32 have a nearly rectangular cross section and are aligned approximately coaxially with each other. In the embodiment shown, the pipe sections 28, 32 are integrally circumferentially closed in cross-section.

The terms "left" and "right" refer to the representation in the Fig. 1 to 3 and 6 and 7, and of course they are not to be construed as limiting the invention.

As Fig. 2 shows when compared to Fig. 1 the pipe sections 28, 32 are omitted, the locking assembly on the right door 14 has a right securing bolt 36 and on the left door 12, a left securing bolt 38. The securing bolts 36, 38 extend perpendicular to the outside 24 of the door wings 12, 14 through the pipe sections 28, 32 and - as will be explained in more detail below - through the spacers 30 and 34 and through the rectangular profiles 26 therethrough.

The securing bolts 36, 38 are encompassed by a padlock 40 with a lock body 42 and a lock bracket 44. As a result, opening of the door leaf 12, 14 is prevented. A removal of the U-lock 40 forward away, as the incomplete representation according to Fig. 2 erroneously suggest, is just prevented by the pipe sections 28, 32 by the inner walls are respectively welded to the locking pins 36 and 38 respectively.

Molded cams 46 can be seen on the spacers 30, 34, which engage in associated recesses on the pipe sections 28, 32 and serve to prevent rotation.

The locking of the U-lock 40 is carried out in a known manner by inserting the lock bracket 44 in the lock body 42 in the axial direction and possibly closing by means of a key 48. The unlocking is done by the operation of a provided in the lock body 42 cylinder lock means of the key 48th Wie in Fig. 1 can be clearly seen, the access to the key 48 is ensured by an end opening 50 in the right pipe section 28. After opening the U-lock 40 and the removal of the lock bracket 44 from the left pipe section 32 opening of the door wings 12, 14 is possible.

This also results in the purpose of the spacers 30, 34, which ensure access to the interior of the pipe sections 28, 32 for removing the lock bracket 44 and the operation of the key 48 even if on the outside 24 of the door leaf 12, 14 the illustrated Guide sleeves 16 or other elements, such as additional reinforcing profiles, are provided.

Fig. 3 shows the locking assembly 10 of Fig. 1 from another perspective, with an illustration of the guide sleeves 16 and torsion bars 18 (FIG. Fig. 1 ) was omitted for reasons of clarity. As already in Fig. 1 1, the end face 52 of the right-hand tubular section 28 lying opposite the opening 50 is inclined with respect to a normal plane to the longitudinal axis of the right-hand tubular section 28, so that the door-facing front side of the right-hand tubular section 28 partially covers the left tubular section 32. This avoids that a gap remains between the two pipe sections 28, 32, which prevents access to the lock bracket 44, for example, for applying separation tools. As a result, an unauthorized opening of the locking assembly 10 is much more difficult.

In Fig. 4 , which is a side view from the left onto the locking arrangement 10 of FIG Fig. 3 represents, the substantially coaxial arrangement of the pipe sections 28, 32 is clearly visible. Fig. 4 illustrates how the lock bracket 44 is received in the left pipe section 32 and the left provided there securing bolt 38 engages.

Fig. 5 represents a right side view of the locking assembly 10 of Fig. 3 and shows the received in the right pipe section 28 lock body 42nd

4 and 5 further illustrate the attachment of the latch assembly to the door panels 12, 14. The locking pins 36, 38 are fixed at one end to the door-facing inner wall of the respective pipe section 28, 32 by means of a welded connection, preferably a friction-welded connection, and penetrate the opposing inner wall, the spacer 30 and 34 and the rectangular profile 26 of the door leaf 14 and 12. In addition, a fastening the securing bolt 36, 38 may be provided on the door-facing inner wall of the respective pipe section 28, 32, for example by welding.

The other ends of the securing bolts 36, 38 are threaded and form end portions 56 for receiving nuts 54 through which the pipe sections 28, 32 can ultimately be bolted to the door wings 14, 12, respectively.

Regarding Fig. 6 the attachment of the locking arrangement 10 to the door wings 12, 14 will be explained below.

First, the spacers 30, 34 placed on the attached to the associated pipe sections 28 and 32 respectively securing bolts 36 and 38, wherein the cams 46 engage in said recesses on the pipe sections 28, 32.

The door leaves 12, 14 are provided in the region of the rectangular profiles 26 with through-mounting holes 58. The secured to the pipe sections 28, 32 and projecting through the spacers 30, 34 securing bolts 36, 38 are inserted through the mounting holes 58 therethrough.

The end portions 56 of the securing bolts 36, 38 are provided with a thread, which may well extend over several centimeters to accommodate different thicknesses of the door wings 12, 14. This makes it possible to attach the locking assembly 10 to doors of different thickness. In particular, the attachment can also be made to such doors, which are reinforced as in the illustrated embodiment in its edge region by rectangular profiles 26.

The attachment is completed by screwing nuts 54 onto the end portions 56 of the securing bolts 36, 38. As in Fig. 6 it can be seen, the spacers 30, 34 are clamped between the door wings 12, 14 and the pipe sections 28, 32, wherein the cams 46 form said anti-rotation.

The locking arrangement 10 described above is characterized by the ease of installation, in which no further modifications to the door wings 12, 14 and / or the container except the two mounting holes 58 must be made.

The sectional view of Fig. 7 clarifies again the protective function of the pipe sections 28, 32, which completely surround both the lock body 42 and the lock bracket 44. Thus, the padlock 40 is also largely protected from the weather, especially from rain, snow or icing, and avoiding corrosion or freezing. An essential advantage consists in the fact that the padlock 40 is protected from any attempts to break up. This break-in protection can be reinforced by using correspondingly resistant materials for the pipe sections 28, 32.

The introduction of the lock body 42 and / or the lock bracket 44 in the respective pipe section 28 and 32 can be additionally facilitated by a corresponding guide insert made of plastic, which can be arranged inside the respective pipe section 28 and 32 - also subsequently. These guide inserts cause alignment of lock body 42 and lock bracket 44 to each other and thus simplify the closing of the U-lock 40. By use various plastic inserts can be adapted to different types of U-locks or -dimensionen.
