Problems solved by technology

A disadvantage of this type of door positioner is the fact that the retaining rod consists of two blades forming a cavity, whereby, for example, the retaining rod is easily deformable through multiple uses of the door
When one of the two blade parts is deformed or both blade parts are deformed, the corrugated profile becomes asymmetrical and the defined holding positions are displaced or disappear, so that positioning of the door is no longer reliable or even possible
Another disadvantage is that the guide rollers not only cause positioning but also guide the retaining rod
Sufficient holding force for stable positioning of the door cannot be achieved with only rolling friction achieved by rollers

Embodiment Construction

[0044] figure 1 A first embodiment of a door locator of the present invention, generally designated by the reference numeral 10, is shown in partial cross-section. The door positioner 10 includes a holding rod 11 and a housing 12 . The housing 12 is fixed by means of screws 13 on a door frame part 1 represented by a dot-dash line 14, while the retaining rod 11 is pivotably received in a bearing seat 2a by means of a bearing hole 11a, which is fixed on a door frame part 1 indicated by a dot-dash line. The line indicated on door 2. At the end facing away from the bearing bore 11 a , the bearing rod 11 has an end stop 11 b which abuts against a stop damper 12 a of the housing 12 .

[0045] The housing 12 is made of an aluminum profile section, which has a central opening 14 for the passage of the retaining rod 11 . In the cylindrical central chamber 12b of the housing 12, two braking mechanisms 15 are arranged opposite to each other transversely to the opening 14, wherein in ...

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).

Description

technical field [0001] The invention relates to a door positioner according to the preamble of claim 1, comprising: a housing fixable to one of the door and the door frame, a swingable A retaining rod fixed to other doors and door frames, and at least one brake mechanism cooperating with a flat side of the retaining rod, the brake mechanism being arranged in the housing, wherein the flat side and the brake The means pre-clamp each other at least in the region of the extension of the holding rod, wherein, depending on the local surface properties of the flat sides and the braking means, a force acting at least in one of the directions of movement of the holding rod retention. Background technique [0002] DE 100 25 185 A1 or WO 01 90 518 A1 disclose a door positioner in which a retaining rod is movably arranged in an opening of the housing. Two locking mechanisms are provided in the housing, which are axially displaceable in the housing and are pretensioned by means of a co...
