Description

The invention relates to a hinge for doors, windows or the like. with a frame hinge fixed to the frame, with a hinge hinge fixed to the sash and with a hinge pin included in the frame and sash loop and connecting the hinge parts with the possibility of rotation around the hinge axis.

Such hinges are known in numerous embodiments. To facilitate the installation of the sash, the hinge pin is most often pre-mounted in one of the hinge parts, often in the frame hinge part. After installing the frame hinge and the hinge hinge at the places provided for this, the frames and sashes can then be hung on the hinge pin by pushing the frame hinge part for the longitudinal recess provided for this, and thereby install in a simple way. The sash can then be removed in any angular position relative to the frame, in which the frame does not block enough longitudinal displacement of the sash in the direction of the hinge axis.

Such hinges always provide sufficient protection against burglary due to removal of the sash hinges in the closed state if the light width between the sash and the frame, when viewed in the direction of the hinge axis, is less than that in the other part of the hinge in which the hinge pin can move axially.

In modern designs of sashes and frames with the so-called "overlap", i.e. those in which the sash is adjacent externally to the front surface of the frame, it is often necessary to have a greater width in the light between the sash and the frame, for example, in order to create more opportunities for alignment and thereby make the edges of the sash and frame facing each other better accessible even when the flaps are closed.

In this case, there is a problem that the sash can even be lifted when closed.

Therefore, the basis of the invention is the task of improving the hinge of the corresponding type in that the closed sash, regardless of the width in the light between the sash and the frame, does not rise and the hinge pin cannot extend. Another objective of the invention is to develop the measures required for this so that it is not difficult to mount and dismantle the sash in the open state.

This problem is solved using the invention reproduced in paragraph 1 of the claims.

Due to the fact that the hinge pin is located in one of the hinge parts with a fixation in the direction of the hinge axis and without the possibility of rotation, it cannot, on the one hand, be pulled out of the hinge part in the direction of the hinge axis, on the other hand, when folding the sash, it performs the corresponding angle of tilt rotation around the axis of the hinge relative to the other hinge part. Since it includes an axial thrust surface in the region included in the other hinge part, which, when the leaf moves, displaces its position on a concentric circle relative to the hinge axis, the other part of the hinge includes an axial mating thrust surface, which is relative to the thrust surface located so that it is in the position of the hinge parts relative to each other, which corresponds to its position with the sash closed, is, when viewed in the direction of the hinge axis, in the overlap abutment surface.

In this case, due to the location and / or dimensions of the abutment surface and the mating abutment surface, an opening area can be set in which the sash can be hung.

Hanging the sash in the case of the hinge according to the invention does not create greater difficulties than in the case of the usual hinge, since the sash must only be hung in the open position by inserting the hinge pin into the longitudinal cavity of the other hinge part.

In a particularly preferred embodiment, the abutment surface is formed by a radially protruding extension, which is provided on an axial extension of a smaller diameter, which extends from the end end of the loop pin.

The other hinge part in this case, for the formation of a mating abutment surface, preferably has a mating extension radially directed from the inner side surface of the longitudinal cavity inward.

A conjugate extension may be formed directly on the longitudinal cavity of the loop portion. Preferably, however, if a bearing sleeve receiving a hinge pin is provided in the longitudinal cavity and a mating extension is provided on the bearing sleeve. In this case, the loop portion can then be economically manufactured by separating the extruded profile. Only the bearing sleeve should consist of a material that is suitable to receive the hinge pin during the life of the hinge with the possibility of rotation and, essentially, without clearance.

Further, the conjugate continuation can be provided on a separate safety ring located in the direction of the hinge axis.

The fixing forces that the hinge according to the invention could perceive in the closed state of the sash are especially high if two radially protruding extensions are provided on the hinge pin and two radially protruding adjoining extensions are provided on the hinge pin. In principle, indeed, the fixation forces are the greater, the greater the number of extensions acting on each other, and the conjugate extensions, and surfaces connected in this way, on which the fixation forces act. It turned out, however, that the location of two opposing extensions is a good compromise between the level of perceived fixation forces and the limitation of the angular region, which does not allow hanging or removing even an open sash.

In a particularly preferred embodiment, one loop portion is a flap loop portion and the other loop portion is a frame loop portion; in other words, counter-protrusions are provided on the frame loop part.

The drawings show an example implementation of the loop according to the invention.

Figure 1 schematically shows a top view of the hinge in a position corresponding approximately to the opening angle of 45 ° not shown in the drawing of the sash;

Figure 2 - the same loop in a top view according to figure 1;

Figure 3 is a cross-section X-X in figure 1;

Figure 4 - the same loop in the same image as in figure 4, however, in the position corresponding to the closed sash;

5 is a loop in a top view according to figure 4;

6 is a section X-X in figure 4;

7 is a view of the same loop in a position in which the opening angle is about 15 °, with the lower hinge part being partially shaded.

The hinge designated in the drawing as a whole with reference numeral 100 includes a sash portion 1 and a frame hinge portion 2.

The hinge hinge part and the frame hinge part are rotatably connected around the hinge axis S by means of the hinge pin 3. For this, the hinge pin 3 of its upper, according to the drawing, area enters into the longitudinal cavity provided in the hinge hinge part (not shown) and is fixed in it in the direction of the hinge axis and without the possibility of rotation around the latter.

The lower, according to the drawing, the region of the hinge pin 3 enters the longitudinal cavity 4 of the frame hinge part 2. It is, as can be seen in Fig. 7, surrounded by a bearing sleeve 5, which consists of a material or combination of materials that provide for the service life of the loop, essentially, clearance-free landing of the hinge pin 3, which rotates in the bearing sleeve 5.

The bearing sleeve 5 is fixed in the longitudinal cavity 4 of the pin of the loop in the direction of the axis S of the hinge using a thread or, as in the illustrated embodiment, by means of a press fit.

At its lower end, as shown in FIG. 7, the end end 6 of the loop end portion 2 of the loop pin 3 has an axial extension 7, the diameter of which is less than the diameter of the loop pin 3. At the free end of the axial extension 7 there are two radially protruding angles of 180 ° continuation 8.

A safety ring 9 is located under the bearing sleeve 5, the inner and outer diameters of which correspond approximately to the inner and outer diameters of the bearing sleeve 5.

As, in particular, from figure 3, the safety ring 9 has a 180 ° offset, inwardly directed, radially protruding mating extensions. The distance between the two edges of the conjugate extensions facing each other is slightly larger than the outer diameter of the axial extension 7.

The extensions 8 form axial abutment surfaces 11 of the loop pin 3, which interact with the formed conjugate extensions 10 of the conjugate thrust surfaces of the frame loop portion 2, if the loop pin is in a rotational position in which the extensions 8 and the conjugate extensions 10 overlap, at least partially, if look in the direction of the hinge axis S.

The safety ring 9 can be inserted into the longitudinal cavity 4 through the part of the longitudinal cavity 4 of the frame loop part 2 provided under the bearing sleeve 5 and provided with an internal thread. For fixing the safety ring 9, the threaded position is pressed against the lower edge of the bearing sleeve 5 a sleeve 13, which is screwed into the internal thread 14 of the lower part 15 of the longitudinal cavity 4.

As can be seen in Figs. 4-6, the safety ring 9 is in an angular position in which, in the case of a closed leaf, the stop and conjugate stop surfaces 11, 12 completely overlap. If now the leaf opens at about 45 ° and the leaf hinge part 1 will be relatively the frame loop portion 2 is brought to the position shown in FIGS. 1-3, the thrust surfaces 11 no longer overlap with the mating thrust surfaces 12, and the hinge pin 3 can be pulled upward from the bearing sleeve 5 in the direction of the hinge axis S, figure 1.
