Abstract

The present invention shows a securing element for installation in a frame of a pivotable window or door which is equipped with an opening limiter. The securing element is arranged in the frame in such a way that one leg of the securing element covers a pin of the opening limiter, via which the limiter arm of the opening limiter is connected to the frame.

Description

The present invention relates to a security element for a window or a door which is equipped with a limit opener. The securing element engages over the bearing block of the opening restrictor on the frame of the window or the door, so that when the door or window is open and the opening angle between the frame and the door or window is held in a locked position by the limit opener, it cannot be levered out without applying considerable force, so that windows secured in this way or the door cannot be opened.

background

Opening restrictors are devices or fittings for windows, balcony doors and doors that ensure that the opening angle of a window sash, balcony door or door is limited to a specified position.

Basically, a distinction can be made between simple opening restrictors for securing a window sash, e.g. for ventilation purposes, and those with requirements for the safety of children. In the case of the latter, the maximum opening of the window must not exceed eighty-nine millimeters. These requirements are regulated in DIN EN 16281 child protection products.

Opening restrictors are usually equipped with a freely positionable end position catch. In this way, different opening widths can be realized and the window sash, the balcony door or the door can be held in the open position.

State of the art

From the DE 66 08 195 U1 a window fitting for pivoting, turning or tilt and turn windows is known. This is provided with a window gear located in the window sash and gear rods extending therefrom in a vertical, horizontal or vertical and horizontal position. There are also window closure, bearing or control members movably arranged and connected to a window sash axis of rotation, which is formed in a known manner by an upper and a lower joint located on the stationary frame. The upper joint consists of a receptacle on the sash for a pin located on the stationary frame and a locking member which can be pushed through a gear rod and which blocks the pin's exit from the trough when the sash is in a closed or an open rotational position.

From the DE 29 616 844 U1 a sliding guide stop piece for an opening limiter of window and door sashes, in particular for tilting sash, opening and / or securing arms which are at least pivotably mounted on a frame of a window or door is known. The sliding guide stop piece is equipped with an elongated hole in which a head bolt at the free end of the deployment and / or securing arm engages both in a pivoting and inclination displaceable manner, the head bolt of the deployment and / or securing arm relative to the elongated hole at one of its limiting Stop end remote point with the sliding guide stop piece can be coupled and uncoupled. At or near the limit stop end of the elongated hole, at the end of the stop piece facing away, there is a passage widening for the head of the head bolt. The area of this passage widening can optionally be released and closed by a fork body which is guided to be limitedly displaceable in the longitudinal direction of the stop piece and which is open in the direction of the limiting stop end. The fork body is constantly supported on the stop piece in the direction of its closed position with an elastic bias.

From the DE 20 2015 008 146 U1 discloses an opening restriction device for a sash of a door or a window. This has an opening limiter and a limiter arm which has a slider. The limiter arm is used for coupling with the wing, the slider being guided along the opening limiter. On the opening limiter there is provided a locking stop that can be moved from a release position into a blocking position and vice versa for cooperation with the slider.

From the DE 10 303 978 B4 a fitting part for a window or a door is known. The window or the door has a wing which can be pivoted about an axis relative to a frame. The fitting part has an opening limiting element which is designed to be permanently connected to the frame or sash and to move the sash or the frame out of contact between sash and frame in the event of a pivoting opening movement, with a predetermined pivoting opening position in relation to a further opening movement, to hold on. The opening limiting element can be switched by a user into two operating states, namely into a first operating state that restricts the opening and into a second operating state that does not have an opening-limiting effect. The opening delimiting element remains in the respectively assumed operating state when the user acts, the opening delimiting element having an arm articulated to the frame or sash, which is connected to a pin of the Has wing or frame in and out of engagement coupling element. The coupling element has an engagement recess for a pin, which is arranged on the end of the arm opposite the axis of the bearing. The coupling element can be pivoted relative to the arm and can thereby be brought into or outside of the engagement area of the pin.

The disadvantage of the known prior art is that the opening limiter locks the window or door in the desired and adjustable open position, but the opening limiter itself is not protected from tampering attempts by third parties in the desired and adjustable open position. It is easy for a third party to loosen the opening limiter on the frame and thus open the window or door. This means that a window or door provided with an opening limiter is not burglar-proof.

task

Compared to the known designs from the prior art, the task is to protect an opening limiter so that it is not easily manipulated and the window or door provided with the opening limiter is locked in the open position and by the opening limiter, not from the outside by a Can be opened by third parties easily and without great effort.
