The invention is based on an inlet coupling for composite sashes of windows, doors or the like a housing arranged in the smaller wing, in which a clutch lever pivotable in the wing plane is mounted, which carries a pivoting coupling approach that is coupled in Position in a laterally introduced into the housing, attached to the larger wing by means of an inlet plate Coupling eye engages.

Inlet couplings in which both parts, namely dome housing and counterpart, in the wood of two wings to be coupled are admitted, have the advantage that when one of them is lowered Wing whose weight does not have to be borne solely by the fastening screws, but Transferred directly to the wood of the other wing via the recessed part of the coupling will. In the case of inlet couplings, however, the disadvantage of manufacturing is compared to the clutches placed on them given by recesses in the wood of the wing for the ao inclusion of the parts of the coupling. Around To be able to produce these recesses in a simple manner, it is already common practice, the housing and the counterpart to adapt the coupling to the shape of a groove cutter, e.g. the two adjacent To give parts of the coupling a circular outline or an outline formed from semicircles and straight lines. Apart from the fact that in this case either the cutouts are made separately in each wing must, which is cumbersome and a certain effort for the precise marking of the second Provides milling, or the larger sash from the rebate side down to the bottom of the milling in the smaller wing must be worked out, which requires a correspondingly large counterpart are Couplings with these shapes have so far been used for locking hooks that can be pivoted transversely to the plane of the wing have been that each have a corresponding training for the left or right-hand installation in the wing have to. In addition, they can generally only be operated with a socket wrench.

The inlet couplings of the type described above have the advantage that they can be used on both sides; no socket wrench or the like is required either. The recesses required for this are however, they cannot be produced in one operation and often cannot be produced from the rebate side either.

The invention is based on the object of designing an inlet coupling of the type described at the outset in such a way that it can be operated by hand and used on both sides of the composite wing, as well as that the inlet coupling required in both wings for composite wing of
Windows, doors or the like.

Recesses can be produced in a single operation are.

This object is achieved by the combination of the features that in the initially described in more detail, according to the hand lever system working inlet coupling, seen from the sash rebate, the Housing and inlet plate have the same depth and nearly the same height, the width of the housing adapted to the diameter of a milling cutter and rounded at both ends accordingly in a semicircle is as well as the upper and lower end portions of the inlet plate corresponding to the circumference of the milling cutter is rounded towards the housing.

Compared to the known clutches, the invention combines the advantages of hand lever actuation for the first time with the fully machine accessibility and the simultaneous right-left use in themselves. As little space as possible is required for the part to be attached in the larger wing, so that No collision with the rod parts to be accommodated there, especially with narrow casement frames Od. The like. Of espagnolette fittings can occur. The rounding of the housing on both sides Inlet coupling enables a stop turned by 180 °. The rounding does not necessarily have to be be a pure semicircle, but can also include a small straight line.

When the upper and lower end portions of the inlet plate are bent according to the shape of the milling cutter and protruding above the surface of the sash easily becomes a Centering of the wings achieved when merging.

In the drawings, an embodiment of the invention is shown. It shows

Claims (2)

Fig. 1 an inlet coupling inserted into the frame of a composite wing in cross section through the frame according to the line A-A in Fig. 3, A b b. 2 the frame in the cross section as in A b b. 1 with an end mill in the working position, Fig. 3 the inlet coupling inserted into the frame in the view of the rebate and A b b. 4 the frames in the view as in A b b. 3, but with prepared wooden recess. The composite window consists of a larger sash 1 and a smaller sash 2. Larger and smaller sashes 1, 2 are rotatable with one another on one side and releasably connected with one another on the other side. An inlet coupling is used in a known manner to establish the releasable connection. The inlet coupling according to the invention consists of the housing 3 fastened in the smaller wing 2 and the inlet plate 4 fastened in the larger wing 1. Lateral openings 8 are also provided in the housing 3, into which a coupling eye 9 attached to the inlet plate 4 can be inserted from one of the two sides. By pivoting the coupling lever 5 towards the wing by means of a handle at its end 10, the coupling eyelet 9 introduced into the housing is penetrated by the mandrel 6 and thus coupling of the two wings 1, 2 is achieved. The housing 3 is rounded at both ends 12 in a semicircle with the radius of a milling cutter, while the inlet plate 4 has only a partial rounding at its end sections 13. Both parts have the same depth, i. That is, they are on the same level as the bottom of the groove and are at the same distance from the rebate plane of the smaller wing 2. They are still almost the same height in terms of their length. With a corresponding face milling cutter, as shown in Fig. 2, the milled recess 14 shown in Fig. 4 is produced, namely with the wings 1, 2 clamped together and in one operation. The housing 3 and the inlet plate 4 are finally inserted and screwed into the cutout in the respective wing 1, 2. To couple the larger wing 1 with the smaller wing 2, the coupling eyelet 9 of the inlet plate 4 engages in the housing 3 through the lateral opening 8. After the coupling lever 5 has been pivoted down, the wings 1, 2 are firmly coupled to one another, the end portions 13 of the The inlet plate 4 is located in the gap between the cutout and the housing 3. In the left-hand window, the parts are mirror images of one another for the graphic representation, i.e. h., the coupling eye engages in the housing 3 through the opening 7. Claims: 1. Inlet coupling for composite sashes of windows, Doors or the like. With a housing arranged in the smaller wing, in which a in the Wing plane pivotable coupling lever is mounted, the one directed in the pivoting direction Coupling attachment carries, which in the coupled position in a laterally introduced into the housing, engages the coupling eye attached to the larger wing by means of an inlet plate, thereby characterized in that, seen from the sash rebate, the elongated housing (3) and the inlet plate (4) are of the same depth and almost have the same height, the width of the housing (3) adapted to the diameter of a milling cutter and Both ends are rounded off in a corresponding semicircle, as well as the upper and lower end sections (13) of the inlet plate (4) rounded towards the housing according to the circumference of the milling cutter is. 2. Inlet coupling according to claim 1, characterized in that the upper and the lower End portion (13) of the inlet plate (4) are bent according to the shape of the milling cutter and protrude over the surface of the sash (1).
