Description

The invention relates to a hinge with a locking device for doors or windows.

The hinge according to the invention is in particular without for glass or acrylic glass doors Frame determined in which the fittings directly on the glass or acrylic glass be attached.

It has long been known to provide hinges with a locking device, which holds the hinges in a certain opening or closing position, so that they are pivoted out of this position only with increased effort can. For example, French patent application 2 408 711 discloses a such an articulation band in which a displaceable in the direction of the articulation axis Locking body acts on a guide body with the control surface facing upwards. The guide body is fixed in place on the wall-side band part, so that do not allow the locking positions of the hinge to vary.

Wrist straps of the type described in the introduction, in which the guide body around the Articulated axis rotatably and a clamping device against the mentioned second band part can be found in the Swiss patent 535,887, U.S. Patent 5,079,798 and European Patent Application 0 599 255 disclosed. All three hinges have a clamping screw for actuating the Clamping device and for locking the guide body essentially in radial direction with respect to the axle pin of the joint accessible. In the above Swiss patent, the guide body is provided with a gap and by means of a clamping screw, which is at a right angle to the joint axis Level runs, can be clamped to the axle bolt. In the US patent, the clamping by a clamping screw acting against the outer circumference of the guide body achieved that runs parallel to the guide of the locking body. By both Hinged hinges are the clamping screw when mounted on the door or window Wrist strap difficult or inaccessible. In EP 0 599 255 A1 the Clamping screw actuated from the side of the hinge and acts on you Pressure body that is pressed against the guide body. This construction allows access to the clamping screw when the hinge is fully assembled. Indeed this construction is quite complex and expensive.

From the publication CH577 100 a door closer is known in which one end of a Linkage arms via a hinge pin and a bearing plate with a door frame connected is. The hinge pin has an upper bearing collar and a lower, in Stepped journal diameter on a protruding from the bearing plate free end has a screw thread for a nut. Through the camp a locking body designed as a locking disc is pressed against the bearing plate when the mother is tightened. Such jamming of a rest or Guide body is unsuitable for the hinges mentioned because their axle bolts have no free end sections for receiving a thread and a nut.

The object of the invention is a simple and inexpensive to manufacture and easy accessible clamping device for the guide body of the hinges mentioned create.

This object is achieved according to the invention by the features of claim 1.

By dividing the axle bolt to create a compression fitting a simple and extremely effective without the need for additional components Clamping device for locking the guide body created. In particular if the pivot is outside the plane of the door or window sash, it is also freely accessible from above or below. The bolt parts can thus be finished built-in hinge can be easily screwed together or apart to clamp the guide body or loosen the clamp connection.

In a particularly simple and inexpensive embodiment of the invention the first bolt part has an end section with an enlarged diameter. This end section is rotatably mounted in a bolt receptacle of the first band part and its shoulder surface lies against the first end face of a bolt receptacle second part of the band. The clamping device has a first part of the bolt Sleeve on which when screwing the second bolt part with the first Bolt part the guide body against the second end face of the bolt receptacle second part of the band presses. Due to the friction between this second face and the surface of the guide body pressed against it, the guide body becomes non-rotatable connected to the second band part.

The second bolt part can be designed as a simple screw that fits into a threaded hole the first bolt can be screwed in. The screw head then acts on one separate cylindrical sleeve, which is on the opposite side against the Guide body presses.

Alternatively, the second bolt part itself can be designed as a threaded sleeve that is on a threaded pin of the first bolt part can be screwed on. To screw it on the threaded sleeve on its free end face a device for engaging a Tool, for example a slot for a screwdriver or a hexagon socket to hold a hexagon wrench. When screwing on this designed as a threaded sleeve second bolt part on the threaded pin of the first bolt part, the jacket of the threaded sleeve presses the guide body against the second end face of the pin receptacle of the second band part.

To increase the friction between the guide body and said second A resilient toothed washer is arranged between these two surfaces, through which the axle bolt protrudes. When screwing the bolt parts and Press the guide body against the second end face of the bolt receptacle the teeth of the resilient lock washer slightly penetrate the material of each other opposite surfaces and create a non-rotatable connection.

In an alternative embodiment of the invention, the first bolt part rotatably, preferably positively, in the bolt receptacle of the second band part held. The guide body is locked in relation to the second band part by radial clamping of the guide body on the axle bolt. This points the first bolt part on a conical section, to which a threaded pin followed. The second bolt part can be screwed onto the threaded pin Threaded sleeve formed. The front area of this threaded sleeve has at least one, preferably two to four longitudinal slots, so that a diameter expansion this front area against the inherent elasticity of the sleeve is possible. When screwing the bolt parts, the front area is on the the conical section of the first part of the bolt is pushed on and widens by a few Micrometer on. The sleeve-shaped second bolt part is with little play in the Guide body inserted. By spreading the front area of the sleeve-shaped second bolt part exerts a clamping force radially outward the hole in the guide body.

The inner surface of the front area of the threaded sleeve is preferably also conical, so that a flat system against the conical section of the first bolt part is achieved.

In a known manner, should be between the bolt receptacles of the first and second Band part plastic washers, which are the friction of the Reduce the pin receptacle to each other and for easy pivoting of the Ensure door or window sash.

Especially when the pin axis of the outside of the door or window level Articulated ligament, it is easily possible on the one provided with the articulated ligaments To arrange a continuous seal on the edge of the frameless door or window sash, which, for example, when using the hinges for articulating a Shower door prevents water from escaping in the area of the wing edge.

the two-part axle bolt of the hinge strap from FIG. 8.

1 to 6 consists of a first band part 1, which is attached to a fixed glass pane 8, and a second band part 2, which a pivotable glass plate 9 is attached. The band parts 1,2 are about Clamping plates 10 clamped onto the glass panes 8.9. The clamping takes place by means of Clamping screws 11, which penetrate holes in the glass panes 8.9. Around to avoid damage to the glass panes 8, 9 (not shown) thin elastic pads made of rubber or elastic plastic between the Glass panes 8.9 and the band parts 1.2 on the one hand and the clamping plates 10 on the other be added.

The band part 1 has two outer bolt receptacles 12, 13. The band part 2 is with provided two inner bolt receptacles 14, 15. In these pin receptacles 12-15 the axle pin 3 is held with little play, the hinge parts 1, 2 articulated with each other combines.

In the middle, a guide body 7 is attached to the axle bolt 3, which with a Locking recess 6 is provided. In the locking recess 6 engages in the locking position of the Articulated ligament (see FIGS. 4 and 5) a roller-shaped locking body 5, which on a Slider 16 is slidably held against the force of a spring 4. The slide 16 is guided in a recess 17 in the first band part 1.

A plastic seal in the form of an " h " can be seen in FIG. 2, which extends over the edges of both glass panes 8, 9 and prevents the escape of water when the door is closed.

The details of the split axle pin 3 of this hinge are in particular in 3 can be seen. A first, lower bolt part 19, which is about the essential Section of the total length of the axle pin 3 extends at its upper End provided with an internal thread 20. In this internal thread 20 is the second Bolt part a screw 21 with a hexagon socket for the engagement of a hexagon wrench screwed. The head of the screw 21 presses against the first one Bolt part 19 pushed on cylindrical jacket-shaped sleeve 22. At the lower end of the first bolt part 19, an end section 23 with an enlarged diameter is provided, which is rotatably mounted in the lower pin receptacle 13 of the first band part 1 and the shoulder surface 24 against the lower end face of the bolt receptacle 15 of the second band part 2 presses. The lower end face of the sleeve 22 presses against the upper End face of the guide body 7.

When screwing the screw 21 into the first bolt part 19, the sleeve 22 presses it Guide part 7 down, whereas the end portion 23, the pin receptacle 15 of the second band part 2 pulls up. In this way, guide body 7 and Bolt receptacle 15 of the second band part 2 pressed against each other, so that the Friction between these elements against a rotation of the guide body 7 the second band part 2 prevented. To increase the friction between the guide body 7 and the second band part 2 there is a resilient toothed washer 25 between the opposite surfaces of the guide body 7 and the Bolt holder 15.

By loosening the screw 21 forming the second bolt part, the pressure is reduced on the opposing surfaces of the guide body 7 and the bolt receptacle 15. When the screw 21 is loosened, the holding force in the recess 6 of the Guide body 7 engaging detent body 5 larger than the frictional force between the guide body 7 and the pin receptacle 15. When the two glass panes 8.9 to each other, the guide body 7 by the locking body 5 rotatably held relative to the first band part 1, wherein it is opposite the second band part 2 twisted.

5 shows, for example, a position pivoted by 30 ° with respect to FIG. 4 the band parts 1,2 shown to each other. If the screw 21 screwed tightly again into the first band part 19, so the above described Way of the guide body 7 relative to the tape receptacle 15 of the second tape part clamped and the locking recess 6 in its position to the second band part 2nd fixed. When the glass pane 9 is pivoted relative to the glass pane 8 (see Fig. 6) the locking body 5 is pressed out of the locking recess 6. The wrist band retains the locking point selected when screwing down and shown in FIG. 5.

This locking point adjustment can slight angular deviations of the levels of glass panes 8.9 to be joined together are compensated for. It is also possible to flange the first hinge 1 to a wall to which the pivotable Glass plate 9 is at right angles in its locking position. In In this case, the fastening plane of the first band part 1 is pivoted through 90 ° the mounting level shown in Figs. 2 and 4 to 6. angular deviations the wall can be used when using the joint band according to the invention Compensate for the adjustment of the locking point of the guide body without any problems.

Finally, the locking point adjustment enables the same hinge for to use different corner constructions. In the drawn in Fig. 4 The glass panes 8, 9 are aligned with each other so that the pivotable position Glass pane 9 formed door in the closed state in extension the fixed glass pane 8. When using the joint band according to the invention on a shower cubicle the journal is outside the cubicle, so that the pivotable glass pane 9 opens to the outside.

It is desirable to have the pivotable glass pane 9 at a right-angled corner articulate, the locking body 7 is in relation to the position in Fig. 4 when released Swivel screw 21 by 90 °. Then tighten screw 21 can the pivotable glass sheet 9 from its rest position at right angles to the glass sheet 8 pivoted out into the position aligned with the glass pane 8 become. Since in the selected construction of the axle pin 3 in the locking position lies within the included right angle (see FIG. 5) and the edges of the Glass panes 8.9 are pivoted quite far apart, this is suitable Articulated hinge not for use in a shower cubicle where the adjoining Edges of the glass panes 8.9 should be sealed to each other. In this case it is Modify construction such that the axle bolt in the locking position outside the included right angle.

Through any choice of the locking positions, the hinge for articulation of the Doors of any cabin shape can be selected. For example, the same length Glass walls connected in pentagonal, hexagonal or octagonal shape be, wherein at least one of the glass walls by means of the invention Articulated hinges is hinged as a hinged door. The selected resting position of the Articulated hinge parts 1,2 defines the required angle to the adjacent glass pane.

7 shows an alternative embodiment of the joint band according to the invention. Here, the second pin part 19 'has the end section 23 at one end enlarged diameter and a threaded pin 26 at the opposite end on. The second bolt part 27 is designed as a threaded sleeve and on the threaded pin 26 screwed on. The closed free end of the threaded sleeve 27 has one Hexagon recess 28 for the engagement of an Allen key. The second, designed as a threaded sleeve 27, presses in the manner described above Bolt part when screwing against the first bolt part 19 'the guide body 7 against the pin receptacle 15 of the second band part 2, so that the guide body 7 is held in a rotationally fixed manner relative to this second band part 2.

Otherwise, the construction elements of the embodiment from FIG. 7 correspond to the Elements shown in Fig. 3, wherein the same parts with the same reference numerals are provided. Between the pin receptacles 12, 13 and 14, 15 of the two band parts 1 and 2 plastic washers 29 are inserted, which the friction when Reduce pivoting of the hinge parts 1,2 to each other.

8 and 9 show a third embodiment of the joint band according to the invention. Again, the same components with the same reference numerals as in provided the previous figures. In this embodiment, the fixation takes place of the guide part 7 by radial clamping.

For this purpose, in the first bolt part 19 ″ connects to the lower end section 23 enlarged diameter to a square-shaped bolt section 30, which in a Square recess of the pin receptacle 15 of the second band part 2 engages. On the square-shaped bolt section 30 is closed by a conical bolt section 31 and a threaded pin 32. On this threaded pin 32 is the second Bolt part screwed a threaded sleeve 27 ', the wall in the lower Area - starting from the open thread end - through four diametrically opposite one another Longitudinal slots is divided. The front area of the wall of the threaded sleeve 27 'is thereby divided into four elastically expandable segments 33.

As can be seen in Fig. 9, the segments 33 in the axial direction on the conical Bolt section 31 of the first bolt part 19 "pressed when the sleeve-shaped second bolt part 27 'screwed onto the threaded pin 32 of the first bolt part 19 " becomes. Through the conical outer surface of the conical bolt section 31 the segments 33 are spread apart and press against the wall of the Bore in the guide part 7. In this way, the guide part 7 is opposite the axle pin 3 "non-rotatably clamped. The axle pin 3" is due to the positive Connection by means of the square-shaped bolt section 30 and the corresponding Square opening in the bolt receptacle 15 rotatably with respect to the second Hinge part 2 held so that the guide body 7 through the axle pin 3 "opposite this second band part 2 is fixed.

To have the largest possible contact area between the inner surface 34 of the threaded sleeve 27 'and the conical bolt section 31, the inner surface 34 in Area of the open end of the threaded sleeve 27 'is also conical.

In the illustrated embodiments, the hinge according to the invention is used for Connection of a glass door to a glass wall. The wrist band according to the invention can but also be designed such that a glass door can be pivoted to a wall or a concrete wall can be connected. The hinge can also be used for connection be designed as a swing door.
