Abstract
Abstract An arrangement for rendering difficult the unauthorized opening of door etc. arrangements on containers which have corner fittings with openings of a non-circular shape. The arrangement enables the security against unauthorized opening of the doors etc. on containers to be increased, using simple means, and it is also possible to remove the arrangements from the said containers when they are not required for the said purpose. A bar or a similar arrangement for preventing opening, which can be fixed across an end wall or another side wall or a roof with a pivotable door arrangement on it, has two locking devices disposed at a mutual distance from each other and adapted to the openings in the said corner fittings, of which at least one locking device can be influenced by a manual influencing member which can be locked to the said bar, the said locking devices being designed so that when the bar and the influencing member are held in a connecting position they can be inserted in the complementary openings in the corner fittings on the container in question, and when in a blocking position they are forcibly retained in the said openings in order to hold the locked bar in place to prevent the container in question from being opened.

An arrangement for rendering difficult the unauthorised opening of the door etc. arrangements (5) on containers (4) which have corner fittings (2, 3) with openings (6, 6 1 ; 7, 7 1 ) of a non-circular shape, characterised in that a bar-type arrangement (1) or a similar elongated arrangement which prevents opening, which can be fixed across an end wall (4A) or another side wall (4B) or a roof (4C) with a pivotable door arrangement (5) on it, has two locking devices (11,12) disposed at a mutual distance from each other and adapted to the openings (6, 6 1 ; 7, 7 1 ) in the said corner fittings, of which at least one locking device (11) can be influenced by a manually operated influencing member (13) which can be locked to the said bar (1), the said locking devices (11, 12) being designed so that when the bar (1) and the influencing member (13) are held in a connecting position (I) they can be inserted in the complementary openings (6, 6 1 ) in the corner fittings on the container (4) in question, and when in a blocking position (II) they are forcibly retained in the said openings (6, 6 1 ) in order to hold the locked bar in place to prevent the container (4) in question from being opened.
Claim 3
Dependent Claim
48 words
An arrangement according to patent claim 1, characterised in that the bar (1) is formed by a preferably telescopic hollow beam (1 1 , 1 2 ) which bears on one (1A) of its free ends the said hollow influencing member (13) which is like a lever arm.
Claim 4
Dependent Claim

Claim 8
Dependent Claim
34 words
An arrangement according to patent claim 6, characterised in that the said hooks (11, 12) are designed to extend along the bar (1) when it is held locked in the said blocking position (II).
Claim 9
Dependent Claim
