Abstract
The invention relates to a door holder, comprising a housing (12) that can be fastened to one door and door frame, a stay bar (11), which penetrates an opening (14) in the housing (12) and can be pivotally fastened to the other door and door frame, and at least one braking member (15), which interacts with a flat side (20) of the stay bar (11) and is disposed in the housing (12), wherein the flat side (20) and the braking element (15) are biased toward each other at least in regions of the extension of the stay bar (11), wherein a retaining force can be produced, which acts at least in one of the displacement directions of the stay bar (11) as a function of the local surface property of the flat side (20) and of the braking member (15). A door holder enabling reliable and safe locking, which may also be produced in a cost-effective manner, can be created according to the invention in that at least either the force application or the local surface property is modified along the extension of the stay bar (11), and that the resulting retaining force thus varies across the extension of the stay bar (11).
