DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention concerns a lock assembly including a first locking means in two parts intended to be attached, e.g. screwed vertically with at least one of its two parts on a door, and a detachable second locking means, intended to be brought on the two parts of the first locking means from above when the door is closed, whereby one of the locking means is showing a projecting portion and the second locking means is showing a recess corresponding to the projecting portion, and whereby the projecting portion is intended to be locked in the recess.
BACKGROUND TECHNICS
The locking assembly according to the preamble preferably is intended to be used for locking of a container door, which as a rule is constituted by a double door at one end of the container. A lock assembly for locking of such a door is known from the Swedish patent publication SE 9003139-4, showing a first locking means in two parts, which parts are intended to be screwed on each of the door leaves of the container, and a detachable second locking means intended to be brought into notches in the parts of the first locking means and locked to one of these parts by means of a padlock.
A drawback with the known lock assembly is that the parts of the split first locking means can be brought out of their position at careless treating of the door leaves causing difficulties in entering the detachable second locking means into the notches in the parts of the first locking means. As the notches in the first locking means are mutually parallel a sticking effect also can arise which also makes the treading of the second locking means more difficult. Also the tongues, by which the padlock keeps the first and the second locking means together, is a weakness in the construction that easily can be demolished by outer effects. The known locking device also shows a relatively complex shape which makes its manufacturing more expensive.
DESCRIPTION OF THE INVENTION
The purpose with the present invention is to bring about a lock assembly according to the preamble which is not showing the drawbacks of the known lock assembly mentioned above. The lock assembly according to the invention is including a first looking means in two parts intended to be brought, e.g. screwed vertically with at least one of its two parts on a door, and a detachable second locking means intended to be brought from above on the two parts of the first locking means when the door is closed. One of the locking means is showing a projecting portion and the second locking means is showing a recess corresponding to the projecting portion.
The lock assembly according to the invention is characterized in that the projecting portion and the recess is showing a mutually corresponding wedge-shaped, that the projecting portion is showing an outwardly directed rim, that the recess is showing an inwardly directed rim, and that the first locking means and the second locking means brought together are arranged in that the outwardly directed rim of the projecting portion hooks behind the inwardly directed rim of the recess.
By the projecting portion and wedge-shape of the recess is achieved that the parts of the first locking means in a simple way can be forced in the right position when the second, detachable locking means is attached even if the parts of the first locking means is not in an exact desired mutual position, eventually by influence of relatively big forces directed from above.
Preferably the two parts of the fix first locking means put together is showing a wedge-shaped projecting portion the tip of which is directed upwards, which is provided with an outwardly directed rim along the sides constituting the wedge-shape, and which is divided along a vertical plane extending perpendicular to the plane through the door, whereby the detachable second locking means is showing a corresponding wedge-shaped recess, the tip of which also is directed upwardly, and which at locking of the door is intended to be brought upon the projecting portion of the first locking means
