Description

The invention relates to a box-shaped housing, in particular for a mailbox, a mailbox or a parcel box with a housing wall and provided in the housing housing opening and a housing opening closing element which is hinged to the housing wall, wherein either the occlusive element or the housing wall carries a first hinge element which cooperates with a second hinge element which is fixed to the respective other component, so the housing or the closing element, for pivotally mounting the element to be closed on the housing wall.

Mailboxes, mailboxes and parcel boxes are known in many configurations. The invention is concerned with such articles, which have a box-shaped housing, which consists in particular of one or more bent sheet metal parts. The housing has outer walls and a housing opening, which by a closable element, for. As a door or a flap, can be closed. Usually, the closable element is connected via a hinge pivotally connected to the housing wall at the edge of the housing opening. It can optionally be provided that the closable element can be fixed in a position closing the housing opening and / or releasing the housing opening at least partially.

In the case of a door, there are different configurations of this door, wherein a simple variant only provides a door leaf, which pivots into the housing opening and optionally can be locked there. However, this simple door leaf can also be swung open onto the housing opening and overlap slightly with the edge of the housing opening.

In another variant, the door has an inwardly curved side wall, which runs in particular parallel to the outer wall of the housing. This side wall is usually bent by 90 ° relative to the door leaf level and gives the door a high rigidity against deformation.

In addition, it is also known, for example from the DE 10 2009 064 508 A1 as well as the DE 10 2010 002 920 A1 in that the angle between the side wall of the door and the base, wherein the side wall is out of the plane of the Base surface is bent towards the interior of the box-shaped housing, an angle α <90 °. For this purpose, corresponding walls can be provided on the box-shaped housing, which preferably run parallel to this side wall of the closing element. Preferably, the closing element and the box-shaped box on all sides mutually parallel side walls.

In addition, it is from the DE 10 2010 002 920 A1 already previously known to provide a bearing block for forming a hinge, wherein the bearing block has a capsule which engages in a curl of a side wall of the occluding member. The bearing block can then be hooked by means of a mushroom-shaped suspension element, which cooperates with a keyhole-shaped receiving opening of the box-shaped housing, in this opening, so that it can then be fixed by means of a screw. The installer then has both hands free for tightening and no auxiliary person is required. The curl forms quasi a sliding bearing, in which engages the capsule as a bolt. For optical reasons, it is disadvantageous that openings for the keyhole-shaped receiving opening and for screwing the bearing block must be provided on the box-shaped housing on the outer wall of the housing-shaped box.

Another attachment of a bearing block is from the DE 693 02 964 T2 previously known, in which case the bearing block in a U-shaped leg clamped, so non-positively held.
