DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an arrangement for rendering more difficult the unauthorised opening of the door mechanism on containers which have corner fittings with openings of a non-circular shape.
It is already known to provide increased security for containers of the above type by permanently fixing a pivotable cross-bar on the outside thereof by welding or bolting; this is designed to be pivoted upon opening so that it co-acts with a hooking device for locking it to the latter across the boundary opening edge of the actual door arrangement. In this case, when fixing the said cross-bar, the said containers have to be acted upon so that their outer surface is deformed and the cross-bars have to accompany the containers whenever they are being transported, even if there are no goods packed inside them.
The main object of the present invention is primarily to provide an arrangement of the above-mentioned type which solves the said problems, and which affords considerably increased security against breaking-in. The said object is achieved by means of an arrangement according to the present invention which is substantially characterised in that a bar-type arrangement or a similar elongated arrangement which prevents 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 openings in the said corner fittings, of which at least one locking device can be influenced by a manually operated 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 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.
The invention is described below by way of a preferred embodiment example, with reference to the accompanying drawings, on which
FIG. 1 shows an arrangement to prevent opening, designed according to the present invention, in a partially cut-away view,
FIG. 2 shows schematically a container with an arrangement according to the invention held in a blocking position,
FIG. 3 shows a partial view of a lower corner fitting with the arrangement held in a connecting position and a blocking position, respectively,
FIG. 4 shows a partial view of an upper corner fitting with the arrangement held in a connecting position and a blocking position, respectively,
FIG. 5 shows the upper part of the arrangement with an influencing member held in a pivoted-out, connecting position, and
FIG. 6 shows a perspective view of a fixed locking device appertaining to the arrangement.
According to the invention a bar-like arrangement 1 with a considerably longitudinal extent, or a similar arrangement for preventing opening, is intended to be releasably connected to an upper and a lower corner fitting 2 and 3 respectively on a container 4, with a view to rendering it more difficult to effect unauthorised opening of the locking arrangements attached to the pivotable doors 5 or other openings disposed in the end walls 4A or in the long sides 4B or in the roof 4C of the container, in that it extends across the said locking arrangements. Connection is made possible by making use of the corner fitting openings 6, 6.sup.1 and 7, 7.sup.1 respectively, which are located in the actual corner fittings 2, 3 and have a non-circular shape, with an accommodating space 8 inside them.
In the present example two pivotable doors 5 are shown; these are located in a short end wall 4A of a container and can be locked to the frame 9 of the container by means of known locking devices 10; the said arrangement 1 can be attached to the said corner fitting openings 6, 6.sup.1 ; 7, 7.sup.1 in that two locking devices 11 and 12 respectively, adapted to the said corner fitting openings 6, 6.
