DE2613760A1 - Combined tilting and rotating windows closing mechanism - has circumferential groove for mechanism actuating rods and seal - Google Patents

Abstract

The four sided closing system is used especially for rotating or combined rotating and tilting windows or for centrally pivoted windows. The frames can be made from timver aluminum or plastics. The sealing ensures in closed position thermal insulation and protection against rainwater. The closing element length can be readily reduced to required dimensions. Individual components are connected readily by overlapping inserted ratchet arrangement. The locking elements are fitted on all four sides of the frame into grooves, including corners. The grooves accommodate locking mechanism and additional circumferential seal. The locking mechanism groove profiles, cut to length are pressed into frame grooves, and the locking system rods are also cut to length and fitted.

Description

Description of the invention with the title:

Four-sided locking system for windows AREA OF APPLICATION: The The invention relates to a locking system particularly suitable for turn-turn-tilt and pivot windows made of wood'aluminium u.

Plastic to achieve optimal a values without an additional lip seal insert.

PURPOSE: Such locking systems basically have their area of responsibility in the guard locking of windows with the most varied of functions under consideration the permissible joint permeability, protection against driving rain and transmission of wind forces the pane on the frame in conjunction with rotating hinges and special Fittings.

PRIOR ART: It is known that t'Staedart versions " in window construction, the locks on the vertical side opposite the axle side are located. These consist of 2nd or, in the case of larger leaves, 3, locking cams in a lock iron embedded in the frame engages. Large wings will be Equipped with central locks, which depending on the version have 1-2 u.

3 locking cams on each side. Pivoting windows are depending on the dimensions with locking cam and iron as well as on the upper vertical side by means of a locking bar locked.

In addition to the types of closure mentioned, in the above stress groups (usually from the 4th floor) rebate seals with a wide variety of shapes and types of fastening introduced.

PRIOR ART REVIEW: To all of these different closure systems to be able to assemble on the respective workpiece and in a wide variety of materials a variety of special milling cutters, drills, etc.

Templates etc. required, each adjusted to the dimensions Need to become.

Next, only a point lock on the lock iron is guaranteed, the any warped material does not compensate and therefore the a-value of the component negatively influenced. The installation of "circumferential rebate seals requires additional Operations and also the sealing profiles may only be used after the painting work has been completed Furthermore, these additional measures are no guarantee for permanent tight closure, since the sealing lips often do not have any warped materials obtain sufficient contact pressure.

In summary, it can be said that all conventional Window locking systems for a multitude of operations and special tools or templates are also required, which naturally affect the selling price of the components knock down. In addition, qualified personnel must always be available are thus the weak points of the systems are kept within limits.

OBJECT: The invention is based on the object of a locking system establish what the guard locking as well as the function of circumferential rebate seals In addition, an a-value of the highest stress group should be in unison can be achieved with perfect protection against driving rain.

SOLUTION: This object is achieved according to the invention in that at Window sashes on all 4 sides and closing elements along the entire edge length around the corner, snap into the milled locking grooves on the frame and thus the task of Take over locking cams and iron as well as additional circumferential seal.

FURTHER DESIGN: Un the locking system for all occurring To be able to use dimensions, it consists of the following components: A. Basic element with gear box for moving the entire system and device to accommodate the movement pin of the handle.

B. Closing elements that can be shortened with a rack grid.

C. Corner transmission element with slide-over grid for toothed rack.

D. Frame locking groove made of rigid PVC.

ACHIEVABLE ADVANTAGES: The advantages that can be achieved with the invention exist especially in the fact that all recesses on the workpiece already after completion of the Pre-work (rebates) are done and thus 2 work steps are saved, or the recesses are already in the prefabricated profile.

Furthermore, all cold bridges of the cases are interrupted, which is also has a positive effect on driving rain safety Material is caught by the strikers, as the moving part (window sash) through the interaction of the locking wedge and locking groove of the shape of the frame is adjusted automatically.

An important point, the derivation of the "wind pressure" of the disc the frame and thus also on the structure is larger than with conventional ones Nockenverschluß.Weiter are also suitable for the assembly of the system, there only the modular parts have to be cut to length on pin and screwed in.

DESCRIPTION OF AN EMBODIMENT: An embodiment the invention is shown in the drawings on a wooden window, and is in Described in more detail below.

It shows: Drawing Jr. 1 required rabbets on wings and frames.

Drawing no. 2 interaction of the parts, horizontal frieze (above), vertical frieze.

Drawing no. 3 interaction of the parts, horizontal frieze (below).

Drawing no. 4 Functional detail section through the basic element.

Drawing no. 5 details of the corner transfer.

Dilation and manufacture of the individual parts of the window such as conventionally known, or. adapted to the load group.

Before assembling the frame, the locking grooves that open Every dimension can be cut into the frame profile using a rubber mallet. Then the normal assembly of the parts takes place after the work has been completed the frame in punoto locking system is ready.

The wings get their required recesses with the profiling the closing rebates by means of a milling cutter tailored to the system.

After the shaping processing has been completed, the modular components are made the locking system by means of a hacksaw of the dimensions of the inner sash rebate customized.

This is followed by the assembly of the parts, whereby attention is generally paid to this You must start with the basic element. The following parts can be accessed using Line up the slide-over grid and clamping sleeve without any problems until one is closed System is achieved.

Retaining screws ensure the secure fit of the entire system which are screwed into pre-drilled holes in the faceplate of the parts.

The execution for plastic or metal windows is done in the same way for this, however, taking into account the respective processing options of the material modified accordingly. L e r s e i t e

Claims (1)

PATENT CLAIMS: General term: 1.Four-sided locking system, strikers, the ensure a tight seal, especially in the case of turn, turn-tilt and pivot windows made of wood, aluminum and plastic. Identifying part: characterized by the fact that the locking system consists of a basic element, closing elements that can be shortened and corner transmission elements, whose Lock wedges as shown in drawing no. 2 by means of a moving rod and connecting pieces Snap into a locking groove in the frame and thus the function of locking cams as well as take over lip seal. Preamble of the dependent claim: 2. Four-sided locking systems Claim 1. Characteristic part of the dependent claim: characterized in that The system can be adjusted to any size using the shortenable closing elements can and the connection between the individual elements by means of a sliding grid the movement rod and collet on the striker is achieved.
