Abstract

A hinged door or window frame has a secondary inwards tilt action. When closed, the door or window is locked in place esp. by the movement in opposite directions of two superimposed rods (3, 4). The rods are operated by a central lever mechanism (5) and protected from external interference by a cover plate (2). The rod tips have T-shaped catches (6, 7,11, 12, 13, 15) which engage with a trap (9, 10).

Description

Locking gear for window or door sashes

The invention relates to a locking mechanism for window or door sashes with drive rods guided on faceplate rails and adjustable in their longitudinal direction via an actuating mechanism, on which locking elements interacting with locking parts fixed to the frame are provided.

Locking gears of this type are well known, are in practical use in large numbers and have proven themselves.

Such locking gears are usually mounted on the finished sash. They can be extended to the corner area of the sash or can be extended further with the respective rod locking gears to the respective cross member.

When manufacturing sashes and windows, there is an increasing tendency to carry out all the necessary fitting work on the loose spar and then assemble the finished spars with the fittings to form the finished sash or window. In connection with the known fittings, the problem often arises that the spars cannot be assembled at the corners easily or without special manipulation, as fittings stand in the way of the necessary joining of the spars. The so-called rod exclusion locks are fundamentally unsuitable for this type of assembly and their use must be avoided in this type of automatic sash or window production. Furthermore, it is disadvantageous in the respective

It is not necessary to couple deflection gears to the corner areas in order to be able to lock these corner areas securely and burglar-proof.

The object of the invention is therefore to design locking gears of the type mentioned at the beginning in such a way that they are suitable both for installation on the finished sash or window or specifically for installation on the loose beam and that all requirements with regard to a secure and burglar-resistant sash locking system can be met.

This object is achieved according to the invention essentially in that two continuous drive rods are provided which are driven in opposite directions by the actuating gear, in particular arranged one above the other and each extend at least approximately over the length of the gear-side spar of the wing, and in that a locking element of one drive rod forms a locking pair which interacts with an associated double locking part with a locking element of the other drive rod.

Through the consistent use of already known locking pairs with locking elements moving in opposite directions in conjunction with, for example, the same double locking parts at all locking points of the respective sash, the tensioning effect achieved with this type of locking between the locking pair and the double locking part is consistently used and thus ensures that even at the critical locking points in the corner areas of the sash, the sash can be secured to the frame in the locking position in a way that fully satisfies the requirements. It is advantageous that the locking points can be positioned immediately adjacent to the respective sash corner.

The drive rods intended for moving the pairs of latches can be arranged one above the other or next to each other or partly next to each other and partly above each other in the respective sash groove.

It is particularly advantageous to use locking gears according to the invention for mounting on a loose beam, in which case the distance between the pairs of latches provided on the beam side and the beam ends is selected in such a way that the automatic assembly of the beams into a closed frame, which usually takes place via linear movements, can take place unhindered by fittings. To this end, the pairs of latches on the beam ends are mounted in such a way with regard to their distance from adjacent beams that they do not hinder the aforementioned assembly, but are arranged as close to the beam end as possible, taking this type of assembly into account.

Further advantageous features of the invention emerge from the subclaims and the following description of an embodiment with reference to the drawing; in the drawing shows:

Fig. 1 is a schematic representation of a locking mechanism according to

of the invention for the gear-side spar of a wing in the unlocked position, and

Fig.2

the locking gear according to Fig. 1 in the locked position.

Fig. 1 shows in a highly schematic manner a locking gear 1 with drive rods 3, 4 guided on a faceplate 2, which in this embodiment are accommodated in the corresponding groove of the beam on which the fitting is to be mounted. The drive rods 3 and 4 are moved in opposite directions to one another by means of an actuating gear 5.

Each of the two drive rods 3 and 4 carries several locking elements, namely a pair of locking bolts 6 and 7 located in the area of the actuating gear 5 as well as pairs of locking bolts 11, 12 and 14, 15 located at the ends.

Each of these pairs of bolts interacts with a locking part provided on the frame side, whereby the locking part 8 is assigned to the pair of bolts 6, 7, the locking part 13 to the pair of bolts 11, 12 and the locking part 16 to the pair of bolts 14, 15.

The locking elements 6, 7; 11, 12; 14, 15 are preferably designed in the manner of head bolts, and the locking parts 8, 13, 16 have recesses 9, 10 complementary to these head bolts, into which the head bolts of a locking pair 6, 7 or 11, 12 or 14, 15 can be inserted laterally while reducing their mutual distance.

Due to the contraction of the respective locking elements of a locking pair (6, 7; 11, 12; 14, 15), the locking part (8, 13, 16) itself can be made very small, which is advantageous because good stabilization is achieved in the wing, few recesses are required overall, no undesirable cross-sectional reductions and resulting weakenings occur and an overall material saving is achieved.

While Fig. 1 shows the locking gear (1) in the unlocked position, Fig. 2 shows the locking position of the locking gear (1). It can be seen that the locking elements 6, 7, 11, 12, 14, 15 are moved towards each other by the opposing movement of the drive rods 3 and 4 via the actuating gear 5 and thereby

have been simultaneously inserted into the recesses 9, 10 of the locking parts 8, 13, 16.

The locking gear according to the invention can be used particularly advantageously when the gear or fitting assembly on the loose spar is carried out practically fully automatically. Due to the avoidance of rod exclusion locks and the achievement of perfect locking even when the locking elements are not arranged directly in the corner area of a sash, all fitting work and subsequent work in connection with the assembly of spars to form a closed sash can be carried out without problems.
