Abstract

Hinged joint for fixing glass doors has both the rest body and rest recess in the joint axis. The rest body and rest recess are arranged along the rotational axis of the joint axis. The first joint axis element is arranged at the first strap (2) whereby the second joint axis element is arranged at the first strap or the second strap (3).

Description

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

A generic hinge is intended especially for glass or acrylic glass doors without frames, in which the hinge is attached directly to the glass or acrylic glass.

To hold the hinge in certain positions, hinge bands are known with locking devices. From these positions (usually open or closed positions) these wristbands are only to be moved with an increased force. For example, is from the FR 2 408 711 a hinge is known in which a displaceable locking body which extends parallel offset to a hinge axis in a hinge part of the hinge, acts on a guide body with upwardly directed control surface. The guide body is fixedly arranged on this hinge part of the hinge, so that the locking position of the hinge can not vary.

A hinge with a locking device, the locking positions are vestellbar, is from the EP 0 599 255 A1 known. In this known hinge a rotational body is arranged around a hinge axis which hingedly connects two hinge parts together, having recesses. In these recesses engages a locking body, which is mounted in one of the two band parts. By means of a clamping mechanism in the form of an accessible from one side of the hinge strap clamping screw and a pressure body of the guide body is fixed, so that the locking positions of the hinge are adjustable as required.

That from the EP 0 599 255 A1 However, known hinge has the disadvantage that it is quite expensive and expensive. In addition, the used in this hinge band adjustment option for preferential positions (for example, an open position or closed position) especially for small hinges unsuitable because they have little building site to accommodate such a locking device.

Another hinge in which preference positions can be set, is from the WO 2004/085778 A1 known. This known hinge has a hinge axis in which a latching body is supported by means of elastic elements in the radial direction, that is perpendicular to the axis of rotation of the hinge axis. In a latching position, the latching body engages in a latching recess, which is arranged in a sleeve arranged around the hinge axis. Also, this adjustment is unsuitable for some small wristbands, as again too much construction space is needed. In addition, the known hinge is to assemble only with increased effort, in particular due to the described detent body.

The invention is therefore an object of the invention to provide a hinge that is easy to build, inexpensive and has an adjustment mechanism for preferential positions, which is particularly suitable for a somewhat small hinge.

This object is achieved with a hinge with the features of claim 1. Further features of the invention will become apparent from the other claims and the description below.

The hinge according to the invention for doors or windows, in particular for glass doors, has at least a first hinge part and at least one second hinge part. The first band part and the second band part are hingedly connected to each other about a hinge axis having an axis of rotation. Furthermore, a locking device is provided, which is arranged within the hinge. The latching device comprises at least one latching body and at least one latching recess. In a detent position (hereinafter also referred to as a detent position), the detent body engages in the detent recess. The detent position thus defines a preferred position in which the hinge is to be held (for example, a Open or closed position). In the hinge according to the invention, both the latching body and the latching recess are arranged in the hinge axis.

The invention has the advantage that the locking device, with the preferred positions (for example, an open or closed position) are adjustable, is located in the hinge axis itself. This also includes that the locking body and / or the recess are itself part of the hinge axis. Such a design is particularly suitable for small wristbands, since only a small building site is needed. Furthermore, the invention enables a low-cost and simple production and assembly.

The latching body and the latching recess are preferably arranged along the axis of rotation in the hinge axis. Thus, the locking body or the recess is movable along the axis of rotation. Alternatively, it is provided that both the latching body and the latching recess are movable along the axis of rotation. It applies to the present application that under the name "along the axis of rotation" and the meaning "exactly on the axis of rotation" and "something laterally offset parallel to this" is understood. In particular, the invention provides in one embodiment that engages in the locking position of the locking body along the axis of rotation in the locking recess.

In a preferred embodiment of the invention, the articulation axis has a first articulation axis element and a second articulation axis element separated therefrom. The hinge axis is thus formed by at least two hinge axis elements. In this case, the first articulation axis element is preferably arranged on the first band part. On the other hand, the second articulation axis element is preferably arranged on the first band part and / or on the second band part. It has been found in practice that the arrangement of the second hinge axis element on both the first band part and on the second band part for reasons of stability is advantageous. The first hinge part preferably has a first bolt receptacle and the second hinge part has at least one second bolt receptacle. The first hinge axis element is in the first bolt receptacle and the second Joint axis element is arranged in the second bolt receptacle. If the first hinge part has two first bolt receptacles, the first hinge axis element is arranged in one of these first bolt receptacles and the second hinge axis element is arranged in the other first bolt receptacle.

In the case of the hinge according to the invention, the first articulation axis element is preferably arranged detachably on the first hinge part. The second hinge axis element is detachably arranged on the second band part. For releasable connection is particularly suitable a screw. For example, by means of a grub screw, the first articulation axis element is fastened to the first band part, preferably in one of the first pin receivers. On the other hand, the second articulation axis element is fastened by means of a further grub screw on the second band part, preferably in the second pin receptacle. By loosening this connection can be adjusted by simply pivoting a preferred position (for example, an open or closed position) of the hinge. By subsequently tightening the grub screws, the preferred position is fixed. Due to the attachment of the two hinge axis elements to the corresponding hinge parts, a relative movement of the first hinge part to the second hinge part will move the latching body out of the latching recess. When returning the first band part to the second band part of the locking body will then engage in the recess again. The hinge is then held in this position.

In a further embodiment of the hinge according to the invention, the latching body is arranged on the first hinge axis element. The at least one latching recess is arranged on the second hinge axis element. Preferably, a plurality of recesses are provided to set, for example, both an open and closed position of a door.

The first hinge axis element preferably has a guide element on which the latching body is arranged. The guide element is in particular provided to take along the locking body during a relative movement of the first hinge part to the second hinge part so as to be guided out of the recess.

Furthermore, it is preferably provided that the first hinge axis element has at least one pressure element which is guided in the direction of the detent body. This pressure element acts on the detent body with a force. This force determines the resistance that must be overcome in a relative movement of the first hinge part to the second hinge part to get the locking body from the recess. Thus, this determines the force that must be applied to pivot the two hinge parts of the hinge.

In a particular embodiment, the aforementioned pressure element is designed as a threaded element, in particular as a screw. Alternatively, it is provided that the pressure element is designed as an elastic element having a first end and a second end. The first end is supported against an adjustment from. On the other hand, the second end is supported against the locking body. This embodiment allows the detent body is always held in the detent position in the recess. However, a pivoting movement of the two hinge parts to each other and thus leaving the detent position quite easily possible because the position and position of the detent body is somewhat flexible due to the elastic arrangement. In addition, it is particularly well possible with this arrangement, to determine the force that is required to guide the hinge from the detent position due to the adjustable with the adjustment, acting on the locking body on the elastic element force.

In a further embodiment of the invention, the first hinge axis element has at least one guide means for guiding the first hinge axis element in the first hinge part. Preferably, a continuous guide means, in particular a thread, is provided, with which the first articulation axis element is arranged on the first band part, preferably in a first pin receptacle.

Also, the second hinge axis element has advantageous embodiments. Thus, in one embodiment of the invention, it is provided that the second joint axis element is designed as a hollow cylinder, which is a Opening which extends along the axis of rotation. The opening thus corresponds to the hollow space of the hollow cylinder. In the opening, an elastic element, preferably a spring (for example, a metal or plastic spring) is arranged, which has a first element end and a second element end. The first element end is supported against a bottom of the second hinge axis element. On the other hand, the second element end is supported against a guide pin on which the at least one latching recess is arranged. In a particular embodiment, the bottom of the second hinge axis element is designed as a bottom guide pin, against which the first element end is supported. The bottom guide pin engages for secure support in a guide means, which is arranged on the first band part, preferably in the above-mentioned pin receptacle. Furthermore, it is preferably provided that both the guide pin and the bottom guide pin have securing elements which engage in at least one guide opening arranged on the second joint axis element.

Figures 1 to 11 show an embodiment in the form of a hinge 1, which is designed as a so-called glass-glass hinge. It serves the hinged connection of two glass modules, namely a glass wall and a glass door. It is already expressly pointed out that the invention is not limited to such wristbands. Rather, the invention can also be implemented on other hinge bands, for example on so-called glass-wall hinge bands, in which a glass door is hinged to a wall.

FIGS. 1 to 3 show the hinge 1, which has a first hinge part 2 and a second hinge part 3. The first hinge part 2 is provided with opposite clamping parts 4 and 5, between which a glass sheet (not shown) is clamped by means of screws 8. In order not to damage the glass, have the mutually facing surfaces of the clamping parts 4 and 5 pad 9, which are preferably made of rubber or plastic. Also, the second hinge part 3 has two clamping parts 6 and 7, which are arranged opposite one another. Between the clamping parts 6 and 7, a glass door (not shown) is clamped by means of screws 8. In order not to damage the glass door, have the mutually facing surfaces of the clamping parts 6 and 7 also upholstery 9, which are preferably made of rubber or plastic.

The first band part 2 has two pin receivers 10 and 11, which are each arranged on an outer side of the band part 2. The band part 3 has centrally a bolt receptacle 12 which engages in the intermediate space which is formed by the two pin receivers 10 and 11 of the band part 2. In the bolt receptacles 10, 11 and 12, a multi-part hinge axis is added, which is described in more detail below.

The hinge axis has a first hinge axis element 13, which is arranged in the bolt receptacle 10 of the first hinge part 2. The first joint axis element 13 is shown in more detail in FIGS. 4 to 6. The first joint axis element 13 is cylindrical in shape and has a thread 14 on its outer periphery. By means of the thread 14, the first joint axis element 13 is arranged in an opening of the bolt receptacle 10, which has a corresponding mating thread.

On its lower side, the first joint axis element 13 has a receptacle 15 for receiving a latching body 18 (see FIG. 2), which is bounded by webs 16 and 17. The locking body 18 is formed in this embodiment as a cylindrical body. In particular, this is a steel pin.

The first joint axis element 13 is further provided with a central bore in which a spring 22 (see Figure 2) is arranged. The spring 22 rests on the detent body 18.

On its upper side, the first articulation axis element 13 has an internal thread 20 in an opening, which is provided for receiving a grub screw 21 (see FIG. Between the grub screw 21 and the spring 22, a spring plate 23 is arranged, which is shown in detail in Figures 10 and 11. The spring plate 23 has a spring pin 24 which engages in one end of the spring 22. At the spring pin 24, a plate member 25 is arranged, which bears against the grub screw 21. In this respect, the spring 22 is supported with one of its ends on the locking body 18 and with the other end on the spring plate 23 and thus on the grub screw 21.

The hinge axis also has a second hinge axis element 26, which is shown in Figures 2 and 7 to 9. The second hinge axis element 26 is provided with a cylindrical pin 27, on which a head part 28 is arranged. The head part 28 has mutually perpendicular recessed recesses 29 and 30, which were introduced into the head part 28 V-shaped. The pin 27 of the second hinge axis element 26 is received in the bolt receptacle 11 of the first hinge part 2 and the bolt receptacle 12 of the second hinge part 3. The bolt receptacle 11 is open only on one side and therefore has no passage opening. The pin 27 of the second hinge axis element 26 is thus securely guided in the bolt receptacle 11.

As can be seen from FIG. 2, the first and the second joint axis elements 13 and 26 are arranged along the axis of rotation of the joint axis. Furthermore, the locking body 18 is arranged to be movable along the axis of rotation. The engagement of the latching body 18 in the latching recess 29 or 30 thus takes place due to a movement of the latching body 18 along the axis of rotation.

The first joint axis element 13 can be fixed in the bolt receptacle 10 by means of a grub screw 32 in such a way that it can not make any relative movement with regard to the bolt receptacle 10 (cf., FIG. 1). It is thus firmly (but again releasably) connected to the bolt receptacle 10. The same applies to the second joint axis element 26. This is connected via a grub screw 33 with the bolt receptacle 12 of the band part 3 firmly (but again releasably) connected (see Figures 1 and 2). In order for good clamping to be achieved, the pin 27 of the second articulation axis element 26 has a corrugation 31 on which the grub screw 33 is pressed.

It will now be explained how preferred positions, namely an open position and a closed position, are set in the described hinge 1. By loosening the grub screw 32 and / or 33, the two hinge parts 2 and 3 can be moved relative to each other by pivoting, without the locking body 18 is brought out of the recess 29 and 30 respectively. The parts of the joint axis rotate accordingly. The band parts 2 and 3 are pivoted to the desired position in which the hinge 1 assumes the closed position. In this closed position engages the locking body 18 in the recess 29 a. Since the latching recess 30 is arranged offset by practically 90 ° to the latching recess 29 and defines a further latching position, an open position of the hinge 1 is automatically defined by the position of the latching recess 30. By tightening the grub screw 32 or 33 or tightening both grub screw 32 and 33 thus the locking positions and thus the preferred positions are determined.

In operation, by pivoting the hinge part 3 about the hinge axis, ie by pivoting the glass door from the closed position, the first hinge axis element 13, the locking body 18, which is located in the limited by the webs 16 and 17 receptacle 15, take. He is therefore removed from the recess 29. Once the glass door has reached the open position, the locking body 18 engages in the recess 30, which defines the open position.

The spring 22 ensures that the locking body 18 is always pressed with a sufficient force in the recesses 29 and 30. Due to the grub screw 21, this force is adjustable. The more the grub screw 21 is screwed in the direction of the locking body 18, the more the spring 22 is compressed. In this respect, the pressure or the force on the locking body 18 increases. Thus, it is possible to determine the force that must be applied so that the locking positions are left. Thus, it is possible to complicate or facilitate the opening and closing of a glass door. Furthermore, it is also possible to counteract thereby wear of the spring 22.

The invention has the advantage that the locking device with which the preferred positions (opening and closing position) are adjustable, is located in the hinge axis itself. Such a design is particularly suitable for small wristbands, since only a small building site is needed. Furthermore, the invention enables a low-cost and simple production and assembly.
