EP3130733B1 - Hinge joint, in particular for windows, doors or the like - Google Patents

Description

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

As a rule, hinge joints of the aforementioned type are used in windows, doors or the like. The scissors bearing is usually attached to the frame, while an associated, associated with the scissor bearing scissors is attached wing side. The connection of the scissors band with the scissor bearing takes place via the bearing pin.

A scissors bearing of the type mentioned is already out of the FR 2 850 420 A1 known. The scissors bearing in this case has a bearing pin for connection to a scissors joint, which is axially displaceable in an associated bearing opening of the scissors bearing between a first, protruding from the scissors bearing position and a second position. The length of the bearing pin is less than the length of the bearing opening, so that the bearing pin is completely received in the second position in the scissor bearing.

Another hinge joint and an associated scissor bearing are from the EP 1 757 762 B2 known. In the known hinge joint, the scissor bearing and the bearing pin form a preassembled module, wherein the bearing pin held captive on the scissor bearing in the preassembled state and the preassembled module can be used both in the right and in the left stop. Incidentally, the bearing pin in the preassembled module is limited axially displaceable and in its end positions in each case equidistant over the upper or lower end of the scissors bearing over. By this supernatant of the bearing pin in both positions a connection of the scissors bearing with the scissor band on the bearing pin is possible both in the right and in the left stop.

While the known from the prior art hinge joint has the advantage that it can be used for both right and left stop, resulting due to the relatively long bearing pin a relative Heavy scissors bearing, which is relatively expensive due to the material costs of the bearing pin.

Object of the present invention is to provide a hinge joint available, which is relatively easy and inexpensive, and can be used as possible even with right and left stop.

The above object is achieved according to the invention essentially by a hinge joint with the features of claim 1. Advantageous developments are the subject of the dependent claims.

In order to prevent falling out of the bearing pin and the other bearing pin from the scissor bearing and on the other to provide a preassembled module available, according to the invention on the other hand stop means for end position positioning are provided between the bearing pin and the other bearing pin on the one hand and the scissor bearing. Ultimately can be by the stop means an exact positioning of the bearing pin and the other bearing pin in the first position and a corresponding positioning in the immersed state of the respective bearing pin in the second position and beyond the ratio of the arrangement of the two bearing pins to each other, if they are provided , realize.

In connection with the present invention, it has also been recognized that the use of a hinge joint is only one possible application in both right and left hand stops. By comparison, it often happens that, on the basis of the customer's request, a (possibly) prefabricated version is made available in which only the right-handed or the left-hand design is provided. The invention realizes this knowledge on the one hand, that while the bearing pin is still axially displaceable in the bearing opening of the scissors bearing, between the first position in which it is maximally ejected, and the second position retracted in contrast, in which he at least with its upper end so far immersed in the bearing opening that it no longer protrudes from the top side of the scissor bearing. Due to the shortening of the bearing pin, which can be considerable in some cases, results in a reduced material usage for the bearing pin and thus reduced material costs. At the same time the weight of the shear bearing is not significantly reduced overall.

Incidentally, in connection with the realization of the present invention, it has been recognized that it does not pose a handling disadvantage if the length of the bearing pin is different from that of the prior art EP 1 757 762 B2 - Is smaller than the length of the bearing opening, as for mounting the scissors band located in the scissors bearing in the second position bearing pin can easily slide out of the bearing opening via a corresponding, introduced from below into the bearing opening tool.

However, the invention also makes it possible to realize the right and left stop in the scissor bearing. For this purpose, in addition to the bearing pin, a further bearing pin is provided which is limited axially displaceable in the mounted state in the bearing opening of the scissors bearing axially displaceable between a first protruding from the scissors bearing position and a second completely absorbed in the scissors bearing position. Structurally, with respect to the scissors bearing, provided that the bearing opening is formed for receiving the other bearing pin. The bearing opening must therefore have such a length in the axial direction or the bearing pin and the further bearing pin must be reduced in length so that when using two bearing pins for both the bearing pin and the other bearing pin axial displacement of the first in the second position is possible.

As a result, in the invention the scissors bearing next to the bearing pin associated with a further bearing pin, which is installed as needed during assembly of the scissor bearing. If, for example, a prefabricated version of the scissor bearing is only desired by the customer for right-handed or left-only stop, only one bearing pin is required. However, if the customer wishes an embodiment of the scissor bearing in which both a left and a right stop are possible, the additional bearing pin is arranged in the bearing opening in addition to the bearing pin. It is at the other bearing pin so an additional component that is additionally installed depending on the design request in the scissor bearing.

In principle, the invention even allows a scissors bearing preassembled with only one bearing pin to be retrofitted with the further bearing pin if this is necessary. This is readily possible in the scissor bearing according to the invention, since the bearing opening for receiving and proper arrangement of the other bearing pin is formed accordingly.

In a particularly preferred embodiment of the present invention, the bearing pin and the other bearing pin are designed to be identical. It is in this case to identical components, so that on the one hand during assembly of the scissor bearing no assembly errors can occur because the bearing pins are ultimately identical. In addition, only a single tool is required for the production of the bearing pin, which reduces the manufacturing cost accordingly.

In connection with the present invention it has been found that it is advantageous if the ratio of the length of the bearing pin to the length of the bearing opening is less than 0.9, preferably between 0.8 to 0.4 and in particular between 0.5 and 0, 7 lies. It is understood that each individual value and each intermediate interval within the aforementioned interval limits is possible and advantageous according to the invention. In particular, ratios of about 0.5, 0.51, 0.52, 0.53, 0.54, 0.55, 0.56, 0.57, 0.58, 0.59, 0.60, are 0 , 61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, and 0.7 are advantageous.

To connect the scissor bearing with the scissors band is provided in an advantageous embodiment that the bearing pin has a protruding in the first position from the scissor bearing outer end portion with a recess. The recess, which is in particular circumferential, ultimately serves to connect the scissors band to the scissor bearing via the bearing pin. Thus, for example, a set screw can be screwed over the scissor band, which engages in the recess in the recess. This then results in a positive connection, so that the bearing pin held in the first position and at the same time the bearing strip is attached thereto.

In a preferred embodiment, the stop means on a recess on the bearing pin for cooperation with a provided in the shear bearing, reaching into the bearing opening stop pin. The recess may be a circumferential recess, which is not necessarily required. However, it is provided in any case that the recess has in the axial direction end-side stop edges with which the stop pin cooperates. The stop pin can be arranged between a radial and a tangential position. It is important in any case that the stop pin engages into the recess on the respective bearing pin.

In an alternative embodiment it is provided that in the scissor bearing is an axially aligned guide slot, which extends from outside of the scissors bearing into the bearing opening. In the guide slot then a stop pin is guided, which is connected to the respective bearing pin. The axial length of the guide slot determines the maximum displacement of the respective bearing pin.

In the context of the stop means it is understood that each of the bearing pins has corresponding stop means. It is also possible in principle that one of the previously described different stop means for each of the two bearing pins is realized. It is therefore not necessarily required that the same stop means are provided for the bearing pin and the other bearing pin.

Incidentally, it has proven to be particularly advantageous that the abutment means of the bearing pin and the other bearing pin are spaced such that the bearing pin and the further bearing pin are non-contact when the bearing pin in the first position and the further bearing pin in the second position , As a result, this means that in the case of mounted bearing tape, so if the bearing pin is pulled out of the scissors bearing for mounting the scissors and at the same time the other bearing pin immersed in the scissors maximum bearing, both pins still do not touch, so that no rattle - Or friction noises can occur.

To avoid contamination of the bearing opening, at least one end cap is provided for opening closure in a preferred embodiment of the scissor bearing. In addition, the use of an end cap is particularly useful when the scissors bearing in addition to the bearing pin has the other, separate bearing pin, which, due to its independence from the bearing pin, could basically survive down over the scissor bearing. By using the aforementioned end cap, which can either be inserted into the bearing opening or can be turned over the bearing body of the scissor bearing, such a protrusion of the further bearing pin in the installed position of the scissor bearing is prevented.

Alternatively or in addition to the aforementioned end cap, it makes sense between the bearing pin and / or the other bearing pin on the one hand and the stop means On the other hand, to provide friction means which serve for the frictional retention of the bearing pin and / or the further bearing pin in the second position against the dead weight of the bearing pin and / or the further bearing pin. Ultimately, the friction means are designed such that the bearing pin does not move away from its position with a vertical arrangement of the scissors bearing due to its own weight, but with the help of a tool without much effort, so already a force that is slightly greater than the frictional force in the Bearing opening pushed into it or can be pushed out of this.

In Fig. 1 a scissors bearing 1, which is for a hinge joint 2, as shown in Fig. 2 is shown is provided. The hinge joint 2 has next to the scissors bearing 1 a scissor belt 3. Here, the scissors bearing 1 is usually provided for frame-side attachment, while the scissors band 3 is provided for wing-side attachment.

The scissor bearing 1 has a bearing pin 4, which is arranged captive in the assembled state in a bearing opening 5 of the bearing body 6 of the scissor bearing 1. The bearing pin 4 and the bearing body 6 of the scissors bearing 1 form a preassembled unit. Incidentally, the bearing pin 4 is between a first position, as this particular in the FIGS. 5 and 6 is shown, and a second position, like this in Fig. 1 is shown, axially displaceable. In the first position, the bearing pin 4 protrudes maximally from the bearing body 6 of the scissor bearing 1, while he is pushed into the second position maximum in the bearing opening 5 of the bearing body 6.

In the scissors bearing 1 or hinge joint 2 is now provided that the longer I of the bearing pin 4 is less than the length L of the bearing opening 5. This has the consequence that the bearing pin 4 in the second position completely in the scissors bearing 1 and the bearing body 6 is taken, that is no longer over the bearing body 6 in the maximum inserted state.

In the illustrated embodiments, the scissors bearing 1 in addition to the bearing pin 4 independent thereof, so separate further bearing pin 7. In assembled condition, as in Fig. 1 illustrated, the further bearing pin 7 in the bearing opening 5 of the bearing body 6 is also axially displaceable between a first from the scissors bearing 1 and bearing body 6 outstanding position and a second, completely in the scissors bearing 1 and bearing body 6 position. In this case, the bearing opening 5 is formed for receiving the further bearing pin 7. This means that the respective lengths of the bearing pins 4, 7 and the bearing opening 5 are coordinated accordingly. The further bearing pin 7 associated first and second position ultimately correspond to the first and second positions of the bearing pin 4. In the in Fig. 1 shown position, the further bearing pin 7 protrudes maximally from the scissors bearing 1 and is thus in the first position. In the presentation according to Fig. 6 the further bearing pin 7 is completely in the scissors bearing 1 or bearing body 6 and thus in the second position.

Incidentally, the bearing pin 4 and the further bearing pin 7 are designed to be identical, as is the case in particular Fig. 7 results. In the assembled state, they are arranged only in the opposite direction in the scissor bearing 1, as well as the Fig. 7 clarified.

Since the bearing pin 4 and the further bearing pin 7 are identical in construction and thus identical, only the bearing pin 4 will be discussed below. The relevant description applies but in the same way for the further bearing pin. 7

In the illustrated embodiment, the ratio of the length I of the bearing pin 4, 7 to the length L of the bearing opening 5 is about 0.57. Larger or smaller ratios Within the range limits specified in the claims are readily possible.

The bearing pin 4 has a protruding in the first position from the scissor bearing 1 and bearing body 6 outer end portion 8, on which a recess 9 is realized. The recess 9 is circumferential in the illustrated embodiment and has, as this particular from Fig. 7 results in a U-shaped cross-section. The end region 8 is, as can be seen from the Fig. 2 to 6 results, provided for connection to the scissor belt 3. For this purpose, the scissors band 3 has a sleeve 10 into which a threaded pin 11 is provided for engagement in the recess 9. For the threaded pin 11, a corresponding bore in the sleeve 10 is provided, which is led into the sleeve opening 12. After screwing the threaded pin 11 projects into the sleeve opening 12 and at the same time into the recess 9 in the end region 8 of the bearing pin 4. In this way, a positive connection between the scissors band 3 and the scissors bearing 1 via the bearing pin 4th

Moreover, 6 stop means for end position positioning of the bearing pin 4 are provided between the bearing pin 4 and the scissors bearing 1 and the bearing body. For this purpose, a circumferential recess 13 is provided on the bearing pin 4, at whose end in each case a stop edge 14, 15 is located. As a bearing-side stop means a stop pin 16 is provided, which is introduced into a corresponding opening of the bearing body 6 and extends into the bearing opening 5 and into the recess 13, as shown in particular from Fig. 1 and 4 is apparent.

It should be pointed out that, instead of the peripheral recess 13, a cut-only recess, which is not circumferential, but in the axial direction has the same length as the peripheral recess, can be provided.

Alternatively to the illustrated embodiment, it is also possible that in the bearing body 6 a the length of the recess 13 corresponding guide slot is provided, in which a connected to the bearing pin 4, 7 stop pin is guided.

As it turns out Fig. 6 shows, the stop means are designed such that the bearing pin 4 and the further bearing pin 7 are non-contact when the bearing pin 4 in the first position and the further bearing pin 7 are in the second position.

Furthermore, it follows Fig. 6 in that the scissors bearing 1 is assigned an end cap 17. The end cap 17 is provided for frictional insertion into the bearing opening 5. The end cap 17 prevents accidental leakage of the other bearing pin 7 from the bearing opening 5 to the first position, as in Fig. 5 is shown.

Alternatively or in addition to the end cap 17 could be realized between the bearing pin 4, 7 and the bearing body 6, a frictional engagement. By frictional engagement, a low frictional force is applied, which is ultimately slightly larger than the net weight of the bearing pin 4, 7. This ensures that the bearing pin 4, 7 can be easily moved from one position to the other position by means of a tool and then remains in the relevant position.

The in the Fig. 1 to 9 illustrated embodiment ultimately shows a scissor bearing 1 and a hinge joint 2 in the design for right mounting. The in the Fig. 10 to 17 illustrated embodiment shows a version for left mounting. This corresponds ultimately to the in the Fig. 1 to 9 illustrated embodiment, wherein the scissors bearing 1 and the hinge joint 2 has been rotated about a horizontal axis. In this case, the further bearing pin 7 assumes the function of the bearing pin 4 according to the first embodiment and is used for connection to the scissor band. 3

Not shown are embodiments for both right and left stop, in which only one of the bearing pins 4, 7 is provided. The respective other bearing pin described above is then omitted. Also, a corresponding stop means for the respective bearing pin is not required in this case. Scherenlager 1 or hinge joints 2 with only one bearing pin 4, 7 are ultimately prefabricated versions with only one specific mounting direction.
