DESCRIPTION

Hinge joint, in particular for windows, doors or the like

The invention relates to a hinge joint, in particular for windows, doors or the like, according to the preamble of claim 1.

Normally the hinge joints of the type mentioned above are used in windows, doors or the like. In this case the bearing support is generally fixed to the frame, while a corresponding hinge wing which is attached to the bearing support is fixed on the side of the blade. The connection of the hinge wing with the bearing support is made through the bearing bolt.

A bearing support of the type mentioned at the beginning is already known from document FR 2850420 A1. In this case, the bearing support for connection to a hinge joint has a bearing pin which is axially displaceable in an associated bearing bore of the bearing support, between a first position in which it protrudes through the bearing support and a second position. Also, the length of the bearing bolt is smaller than the length of the bearing bore, so that in the second position the bearing bolt is completely housed in the bearing bracket.

Another hinge joint and a corresponding bearing support are known from EP 1757762 B2. In the known hinge joint, the bearing bracket and the bearing bolt form a preassembled module, so that in the pre-assembled state the bearing bolt is held captive in the bearing bracket and the preassembled module can be used both in case of swing to the right as in that of swinging to the left. Otherwise, the bearing bolt in the preassembled module can be displaced axially in a limited manner and in its respective equidistant end positions links with the upper or lower end of the bearing support. By this projection of the bearing pin in both positions a connection of the bearing support with the hinge wing is possible through the bearing bolt, both in the case of swing to the right and in the swing to the left.

While the hinge joint known from the state of the art has the advantage that it can be used both in the case of swing to the right and in the swing to the left, due to the bearing pin quite long results in a bearing support relatively heavy, which is relatively expensive due to the material costs of the bearing pin.

The object of the present invention is to provide a hinge joint which is made relatively light and inexpensive and which can also be used both in the case of a swing on the right and on the swing on the left. The object mentioned above is achieved according to the invention essentially by a hinge joint with the features of claim 1. Advantageous improvements are the content of the dependent claims.

In order, on the one hand, to prevent the bearing bolt and the other bearing bolt from falling out of the bearing support and, on the other hand, to provide a preassembled module, according to the invention, for the positioning in the end positions, stop means are provided. between the bearing bolt and the other bearing bolt, on the one hand, and bearing support on the other hand. Finally, by the stop means, exact positioning of the bearing pin and of the other bearing bolt in the first position and a corresponding positioning in the inserted state of the respective bearing bolt in the second position and also also the ratio of the provision of the two bearing bolts to each other, provided these are provided.

In the context of the present invention, it has also been recognized that the use of a hinge joint, both in the case of a swing on the right and on the swing on the left, represents only one possible application case. It is relatively usual that, depending on the desire of the corresponding customer, a (possibly more) prefabricated realization is provided in which only the realization is planned on the right or on the left. The invention implements this recognition, so that on the one hand the bearing pin is axially displaceable in the bearing bore of the bearing support and is located between the first position in which it is displaced to the maximum outwardly and the second position in which on the contrary it is introduced, so that at least with its upper end it is immersed in the bearing hole, not protruding already above the bearing support. Due to the shortening of the bearing bolt, which can be considerable in part, there is a reduced use of material for the bearing bolt and, therefore, reduced material costs. At the same time, the weight of the bearing support is not significantly reduced overall.

Moreover, in relation to the embodiment of the present invention, it has been recognized that it does not represent a drawback in the handling that the length of the bearing pin - unlike the state of the art corresponding to EP 1757762 B2 - is smaller than the length of the bearing hole, since for the mounting of the hinge wing the bearing bolt that is in the bearing support in the second position can be slid out without problems by means of a corresponding tool inserted below into the hole of the bearing. bearing.

However, as regards the bearing support, the invention also makes it possible to carry out the swing to the right or to the left. For this purpose, in addition to the bearing bolt, another bearing bolt is provided, which in the state mounted on the bearing bore of the bearing bracket can be displaced axially in a limited manner between a first position in which it protrudes through the bearing support and a second position in which it is completely housed within the bearing support. As for the construction, with respect to the bearing support it is provided that the bearing hole is made to receive the other bearing bolt. Therefore, the bearing hole must have such length in the axial direction or the bearing bolt and the other bearing bolt must be reduced in length, so that if two bearing bolts are used, both for the bearing bolt as for the other bearing bolt, an axial displacement from the first to the second position is possible. As a result, in the invention, another bearing bolt is associated with the bearing support in addition to the bearing bolt, which is incorporated if necessary during the mounting of the bearing bracket. If, for example, the customer wants a prefabricated version of the bearing support only for swinging to the right or only for swinging to the left, only one bearing bolt is necessary. However, if the customer wishes an embodiment of the bearing support in which both a left and a right wing are possible, in addition to the bearing bolt, the other bearing bolt is arranged in the bearing hole. As for the other bearing bolt, it is an additional component which, depending on the desire to make it, can be additionally incorporated into the bearing support.

Essentially the invention even allows a preassembled bearing bracket with only one bearing bolt to be retrofitted later with the other bearing bolt when necessary. This is possible in the case of the bearing support according to the invention, since the bearing hole is correspondingly designed for the reception and correct positioning of the other bearing bolt.

In a particularly preferred embodiment of the present invention, the bearing bolt and the other bearing bolt are made with the same type of construction. In this case, they are identical components, so that, on the one hand, assembly errors can not occur during the mounting of the bearing support, since the bearing bolts are identical in the end. In addition, only one tool is necessary for the production of the bearing bolt, which correspondingly reduces the manufacturing costs.

In connection with the present invention it has been found to be advantageous if the ratio of the length of the bearing pin to the length of the bearing hole is less than 0.9, preferably between 0.8 and 0.4 and in particular between 0.5 and 0.7. It is understood here that each individual value and each intermediate interval within the range limits mentioned above is possible and advantageous according to the invention. In particular, ratio values of approximately 0.5, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, are advantageous. 0.60, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69 and 0.7.

For the connection of the bearing bracket to the hinge wing, in an advantageous embodiment it is provided that the bearing bolt has an outer end area with a recess that protrudes from the bearing support in the first position. The recess, which in particular is circumferential, finally serves for connecting the hinge wing to the bearing support through the bearing pin. Thus, in the recess, for example, a thread bolt can be screwed onto the hinge wing, which is applied to the recess. This results in a positive form connection, so that the bearing pin is held in the first position and at the same time the bearing wing is fixed thereto.

In a preferred embodiment, the stop means have a recess in the bearing bolt to cooperate with a stop bolt provided in the bearing support that reaches the bearing bore. As for the recess, it may be a circumferential notch, although this is not necessary. However, in any case, it is provided that the recess in the axial direction has abutting edges on the end side with which the stop bolt cooperates. The stop bolt can also be arranged between a radial and a tangential position. It is important, in any case, that the stop bolt be applied in the recess in the respective bearing bolt. In an alternative embodiment, provision is made in the bearing support for an axially aligned guide groove extending from the outside of the bearing support to the bearing bore. A stop bolt, which is connected to the respective bearing bolt, is then guided in the guide groove. The axial length of the guide groove also determines the maximum displacement section of the respective bearing bolt.

With respect to the stop means, it is understood that each of the bearing bolts has corresponding stop means. In this case, it is also essentially possible that each of the different stop means described above is made for one of the two bearing bolts. Therefore, it is not strictly necessary that the same stop means for the bearing bolt and for the other bearing bolt be provided. Moreover, it has been found to be particularly advantageous that the stopper means of the bearing bolt and the other bearing bolt are separated such that the bearing bolt and the other bearing bolt are not in contact when the bolt of the bolt of the bearing bolt and the other bearing bolt are separated. Bearing is in the first position and the other bearing bolt is in the second position. As a result, this means that in case the bearing wing is mounted, if the bearing bolt is removed from the bearing bracket for mounting the hinge wing and at the same time the other bolt Bearing is immersed to the maximum in the bearing support, however both bolts do not touch, so no rattling or friction noises can occur.

To prevent soiling of the bearing hole, at least one end cap for closing the hole is provided in a preferred embodiment of the bearing support. In addition, the use of a final cover is particularly useful when the bearing support in addition to the bearing pin has the other bearing pin separated which, due to its independence from the bearing pin, could protrude essentially below the bearing support. By the use of the aforementioned end cap, which can either be inserted into the bearing hole or placed like a cap on the bearing body of the bearing support, such a protrusion of the other bearing bolt in the mounting position of the bearing bracket.

Alternatively or in addition to the end cap mentioned above, it is possible to provide between the bearing bolt and / or the other bearing bolt, on the one hand, and the stop means, on the other hand, friction means, which serve for the support with positive frictional connection of the bearing bolt and / or of the other bearing bolt in the second position against the own weight of the bearing bolt and / or of the other bearing bolt. Finally, the friction means are made in such a way that in case of a perpendicular arrangement of the bearing support due to its own weight the bearing pin does not move out of position, but with the help of a tool without much effort, it is to say already with a force slightly greater than the force of friction, can be introduced into the bearing hole or extracted from it.

In FIG. 1 there is shown a bearing support 1 which is provided for a hinge hinge 2 as shown in FIG. 2. The hinge hinge 2 has in addition to the bearing support 1 a hinge wing 3.

Also, the bearing support 1 is usually provided for fixing on the side of the frame, while the hinge wing 3 is provided for fixing on the side of the leaf.

The bearing support 1 has a bearing bolt 4, which in the assembled state is disposed captively in a bearing hole 5 of the bearing body 6 of the bearing support 1. The bearing bolt 4 and the bearing body 6 of the support of bearing 1 form a preassembled module. Otherwise, the bearing bolt 4 is axially movable between a first position, as shown in particular in FIGS. 5 and 6, and a second position, as shown in FIG. 1. In the first position, the the bearing pin 4 protrudes as much as possible over the bearing body 6 of the bearing support 1, while in the second position it is fully inserted into the bearing hole 5 of the bearing body 6.

As for the bearing support 1 or the hinge joint 2, it is provided here that the longer the bearing pin 4 is, the smaller the length L of the bearing hole 5. This has the consequence that the bearing pin 4 in the second position is completely housed in the bearing support 1 or the bearing body 6, that is, in the fully inserted state it no longer protrudes through the bearing body 6.

In the illustrated embodiments, the bearing support 1 has, in addition to the bearing bolt 4, another separate bearing bolt 7, independent of the first. In the assembled state, as shown in FIG. 1, the other bearing bolt 7 is axially displaceable in the bearing hole 5 of the bearing body 6, also between a first position in which it protrudes through the bearing support 1 or the bearing body 6 and a second position in which it is completely housed in the bearing support 1 or bearing body 6. In this case, the bearing hole 5 is made for receiving the other bearing bolt 7. This means that the respective lengths of the bearing bolts 4, 7 and the bearing hole 5 are correspondingly coordinated with each other. The first and second positions associated with the other bearing bolt 7 ultimately correspond to the first and second positions of the bearing bolt 4. In the position shown in FIG. 1, the other bearing bolt 7 projects at the maximum through the bearing support. bearing 1 and, therefore, it is in the first position. In the representation according to FIG. 6, the other bearing bolt 7 is completely in the bearing support 1 or bearing body 6 and, therefore, in the second position.

For the rest, the bearing bolt 4 and the other bearing bolt 7 are made with the same type of construction, as can be deduced in particular from FIG. 7. In the assembled state, they are arranged in the bearing support 1 only in the opposite direction, as illustrated also in Fig.7.

Since the bearing bolt 4 and the other bearing bolt 7 have the same type of construction and are therefore made identical, only the bearing bolt 4 will be explained below. The description relating thereto applies to the same. way also for the other bearing pin 7.

In the illustrated embodiment, the ratio of the length I of the bearing bolt 4, 7 to the length L of the bearing hole 5 is approximately 0.57. Relationships greater or lesser within the range limits specified in the claims are possible without further ado.

The bearing pin 4 has an outer end area 8 which protrudes in the first position via the bearing support 1 or the bearing body 6, in which a recess 9 is formed. The recess 9 is circumferential in the illustrated embodiment and has, as in particular from FIG. 7, a U-shaped cross section. The end zone 8 is provided, as can be seen from FIGS. 2 to 6, for connection to the hinge wing 3. For this purpose, FIG. , the hinge wing 3 has a sleeve 10 in which a threaded bolt 11 is provided for its application in the recess 9. For the threaded bolt 11 a corresponding perforation is provided in the sleeve 10, which is made up to the sleeve bore 12. After screwing on the threaded bolt 11, it protrudes into the sleeve hole 12 and at the same time in the recess 9 in the end area 8 of the bearing bolt 4. This results in a connection with positive connection between the wing d e hinge 3 and the bearing support 1 through the bearing bolt 4.

Furthermore, stop means for positioning in the end positions of the bearing bolt 4 are provided between the bearing bolt 4 and the bearing support 1 or the bearing body 6. For this purpose, bearing bolt 4 is mounted on the bearing bolt 4. A circumferential notch 13 is provided at its end, with a stop edge 14, 15, respectively. As stop means on the bearing side, a stop bolt 16 is provided, which is inserted into a corresponding hole in the bearing body 6 and protrudes in the bearing hole 5 and in the recess 13, as can be seen in particular in FIGS. 1 and 4.

It should be noted that instead of the circumferential notch 13, a notched notch can also be provided which is not circumferential, but which in the axial direction has the same length as the circumferential notch.

As an alternative to the illustrated embodiment, it is also possible for a guide groove corresponding to the length of the recess 13 to be provided in the bearing body 6, in which a stop bolt attached to the pin is driven. bearing 4, 7.

As is otherwise apparent from FIG. 6, the stop means are made such that the bearing bolt 4 and the other bearing bolt 7 do not contact when the bearing bolt 4 is in the first position and the other bolt is in the first position. of bearing 7 is in the second position.

Furthermore, it is deduced from Fig.6 that a final cover 17 is associated with the bearing support 1. The end cap 17 is provided for the insertion with positive friction connection in the bearing hole 5. The end cap 17 prevents the Another bearing pin 7 is undesirably exited from the bearing hole 5 to the first position, as shown in FIG. 5.

Alternatively or in addition to the end cap 17, a positive friction connection could also be made between the bearing pin 4, 7 and the bearing body 6. A low frictional force is applied by the positive friction connection, which is slightly larger than the weight of the bearing bolt 4, 7. This ensures that the bearing bolt 4, 7 can be moved without problems from one position to the other position with the help of a tool and then remain in the position in question.

The embodiment shown in FIGS. 1 to 9 finally shows a bearing support 1 or a hinge joint 2 in the embodiment for mounting to the right. The embodiment shown in Figs. 10 to 17 shows an embodiment for mounting to the left. This corresponds finally to the embodiment shown in FIGS. 1 to 9, the bearing support 1 or the hinge joint 2 having been rotated about a horizontal axis. In this case, the other bearing bolt 7 assumes the function of the bearing bolt 4 corresponding to the first embodiment and serves for connection to the hinge wing 3.

Embodiments are not shown for both the right-hand wing and the left-hand leaf, in which only one of the bearing bolts 4, 7 is provided. The other respective bearing bolt described above is omitted. Neither in this case are corresponding stop means necessary for the bearing pin in question. The bearing supports 1 or the hinge joints 2 with a single bearing bolt 4, 7 ultimately represent prefabricated embodiments with only a specific mounting direction.
