Description

The invention relates to a locking linkage for a door closing device, with a first linkage arm and a second linkage arm, wherein the first linkage arm and the second linkage arm are articulated to each other by means of a main joint.

Locking rods are known from the prior art, for example JP 2014 - 218 775 A or off JP 2015 - 068 160 A , With these locking rods of the first linkage arm can be determined against the second linkage arm, so that a successful by means of a door closer drive the Feststellgestänges is blocked. In this way, a door leaf can be held in an open position relative to a door frame, for example, to achieve a detection in an open position, for example for ventilation purposes.

In the known Feststellgestängen is problematic that these are complex in construction and handling, since, for example, an additional tool is required to attach a locking bar on the boom arms or to solve it. In addition, the locking function is often not sufficiently safe because a snap-in arm can accidentally disengage, so that the determination unintentionally triggers.

The invention has for its object to provide a Feststellgestänge with simple structural means a reliable statement. A cost effective solution is an advantage. A retrofit solution is desirable.

The invention solves the above object with the features of claim 1. Thereafter, the Feststellgestänge is characterized in that an auxiliary link is provided, which is articulated to the first linkage arm or the second linkage arm via a first pivot point and that the additional link on a second Hinge point on the other linkage arm is articulated and slidably mounted along the longitudinal direction of the auxiliary link relative to the second pivot point, wherein the first link arm and the second link arm can be determined relative to each other by cooperation of the first pivot point or the second pivot point with the additional link.

By the additional link, the main joint can be blocked by the first linkage arm and the second linkage arm are determined relative to each other. In this case, a reliable connection is achieved by the coupling of the additional link with the link arms at two hinge points, with accidental release of the detected condition is largely avoided. In addition, the handling is simplified, since the additional link can remain in the determined and unconfirmed state of the link arms. A determination is made by cooperation of the first hinge point or the second hinge point with the auxiliary link, wherein the first or the second pivot point acts in the detected state on the auxiliary link such that these are no longer displaced relative to the first or second pivot point due to the action of the door closer can and therefore is determined. Only by applying an additional force by an operator, for example by operating a door leaf, this finding is overcome and the rod arms can move relative to each other. By the first linkage arm and the second linkage arm each having a hinge point or are prepared for receiving such a hinge point, for example by a recess, in particular a bore with internal thread or a groove, a later retrofitting of an additional link is made possible.

The first linkage arm may be a linkage lower arm. The second linkage arm may be a linkage upper arm. The main joint may be formed such that the linkage arms are each hinged together at the end (at a free end).

The additional link may be rod-shaped. The displaceable mounting of the additional link at the second pivot point can be designed such that the additional link is axially displaceable relative to the second pivot point, for example axially displaceable (displacement along the longitudinal axis of the additional link).

The locking linkage is a lever linkage, which is suitable for transmitting power between a door closer and a door leaf or door frame and can be locked or locked in at least one specific position by the additional link. The first and the second linkage arm may each have at the end facing away from the main joint end a connection or a receptacle for a closer shaft of a door closer or an axis of a bearing block, which serves for example for pivotally mounting a linkage arm on a door frame.

In the context of a preferred embodiment, one of the two pivot points and / or the additional link can be set up such that the additional link locks or clamps in the locked state at one of the two pivot points. With In other words, the additional link locks or clamps with its axially displaceable portion on or in the one of the two hinge points. This allows a structurally simple and technically reliable determination of the rod arms of the Feststellgestänges and thus a door leaf.

Advantageously, the locking function can be switched on and off. Hereby the locking function can be selectively activated and deactivated according to the user requirements. Thus, a door can be determined depending on the existing door pass requirements or the weather conditions in the open position or spent after opening the door in the closed position. This has application-related and energy advantages (room temperature control). The switching on and off can be done by acting on the additional link and / or on one of the two pivot points pushbutton or lever.

Conveniently, the clamping force causing a clamping between the one of the two pivot points and the auxiliary link can be adjusted. Thus, the locking function can be adapted to environmental conditions (for example wind conditions) and to a door leaf (size and weight), so that on the one hand a reliable detection and on the other hand a release of the determination by applying an appropriate force on the door is made possible by an operator. An adjustment of the holding force can be done by a knurled screw or by an adjustable preload between the additional link and the pivot point (for example, by a displaceable clamping piece).

Within the scope of a preferred embodiment, the first pivot point may be 5 to 35 percent, preferably 10 to 30 percent, more preferably 15 to 25 percent, of the length of the linkage arm on which the first pivot point is located along the longitudinal direction of that linkage arm be spaced apart the axis of the main joint. Increasing this distance (fulcrum distance) reduces the holding forces required for a determination, so that due to lower material usage and / or choice of a more easily processable material, a cost-effective design of an additional link is made possible.

Advantageously, the linkage arm, on which the first pivot point is arranged, have a plurality of passages or a guide, so that the position of the first pivot point is adjustable on this linkage arm. Thus, the door open angle can be at least roughly adjusted. This can be done by placing the first hinge point in one of the multiple passages, which may be formed as bores, in stages. In the case of a guide which may be formed as a groove or slot in this linkage arm, a stepless adjustment of the Türoffenhaltewinkels is possible. By adjusting the position of the first pivot point on this linkage arm, the holding force of the door leaf and thus also the force can be set, which must be applied by a user to release the determined position on the door leaf.

Conveniently, the linkage arm, on which the second pivot point is arranged, have a plurality of passages or a guide, so that the position of the second pivot point is adjustable on this linkage arm. Hereby, too, the door-open-angle can be at least roughly adjusted. As described in connection with the first articulation point, the setting in the case of multiple passages (holes) in steps or in the case of a guide (groove or slot in this linkage arm) can be made continuously.

As part of a preferred embodiment, the angle between the first linkage arm and the second linkage arm can be adjusted by fixing the additional link at the first pivot point in the desired position. This allows an alternative adjustment or fine adjustment of the door-open angle. The adjustment can be done by the additional link fixed at the first pivot point, in particular clamped, is.

Specifically, the auxiliary link may be formed as a rod with a round cross-section and the second hinge point may have a corresponding with the rod passage. Due to the low material usage can be provided in this way a structurally simple and cost-effective additional link and thus a total cost locking rod. On the passage of the second pivot point can act a locking element or a clamping element, such as a button, lever or a thumbscrew.

Alternatively, the auxiliary link may be formed as a rod with a rectangular cross section and have a slot and the second hinge point may have a corresponding with the slot guide member. By virtue of the rod with a rectangular cross-section, high forces can be transmitted due to the comparatively large area on which a clamping element, for example a knurled screw, can act (clamping force). The guide element may be formed as a bolt, pin or screw.

In the context of a preferred embodiment, the additional link may have a material thickening at a latching point and / or at a clamping point, which cooperates with the second hinge point. This is a constructive way simple and technically reliable locking or clamping action created.

It is also conceivable that the additional link is formed as a molded part, which has at least in the region of the second pivot point at least partially parallel mold sections and that the second hinge point has a corresponding with the mold sections guide member. In this way, a structurally simple additional link can be realized, since this can be produced by a forming process. The molded part may be formed as a wire-shaped part, which is formed by forming a wire, in particular with a circular cross-section. The second hinge point may comprise a pin with guides for molding sections. In addition, a clamping piece may be provided, which surrounds the molding sections or is penetrated by these passages in the clamping piece. By moving the clamping piece along the longitudinal direction of the auxiliary link, the bias acting on the pin can be adjusted.

In concrete terms, the additional link may have a taper at a latching point and / or at a clamping point. As a result, a locking function can be realized with simple structural means. In this case, the taper can be formed by shaped part sections, which have a reduced distance from one another in comparison to other shaped part sections. For switching the locking function on and off, the second pivot point can have a lever rotatable relative to the linkage arm, on which the second pivot point is mounted, with contact sections rotatably connected to the lever, wherein the contact sections block displacement of the additional link, at least in a first position allow at least in a second position, a displacement of the additional handlebar.

The object mentioned above is also achieved by a door closing device with the features of the independent claim. With regard to the advantages, reference is made to the explanations on the locking linkage.

For advantageous embodiment of the door closing device may be used in the context described with the locking linkage measures.
