1. Field of the Invention
The invention relates to a hinge strip, in particular for double-action glass doors, with a fixed hinge portion, a door hinge portion pivotable about the fixed hinge portion, a pivoting axis penetrating the fixed hinge portion and the door hinge portion, a cam with at least one depression being disposed at said axis, and with a force-loaded roller, which cooperates with the cam.
2. Prior Art
It is desirable in hinge strips to dispose a latching device in the hinge strip to be adjustable to compensate for tolerances when affixing a bearing block at a wall or the like.
EP 0 599 255 A1 describes a hinge strip for double-action glass doors, which allows for correcting the latching position of the door leaf in the mounted condition, to adapt to unevenness of the wall. A body of revolution, rotating about an articulated axis of the hinge strip is disposed in a bearing block screwable to the wall or the like, and which can be locked in different positions with regard to the bearing block. On its exterior circumference, the body of revolution has latching positions into which a spring-loaded latching body engages, which is guided at the pivotable door hinge portion. In this case, the latching body may be supported at a sliding body, which is spring-loaded and displaceable in a carrying body which forms a component of a door hinge portion. In the known device, the ball-shape configured latching body is disposed in the pivotable hinge portion, and serves to secure the door in the closed or in the opened position. Correcting the position of the door leaf in the mounted condition is realized via another sphere or cylinder securable between the bearing block and the body of revolution, which procedure is not precise at all.
An object according to one embodiment of the invention is an easy way of correcting the latching position of a double-action door in the mounted condition, which allows for a precise adjustment of the zero position of the door.
According to one embodiment of the invention, the roller is disposed to be orthogonally adjustable with regard to the longitudinal axis of the hinge strip. This allows for very small and precise adjusting ranges, such that the zero position of the door can be exactly set.
One embodiment of the invention provides a hinge strip, the fixed hinge portion thereof, to adjust the door leaf in its closed position when compensating for building tolerances in the connecting area—for example a wall—being adjustable with regard to the door hinge portion such that, even after a long period of operation, the door leaf maintains the once adjusted closing position.
In the following, further advantages and embodiments of the invention will be explained in detail based on one possible diagrammatically illustrated embodiment, in which:
According to
The door hinge portion 2 comprises at least a first clamping plate 3 and a second clamping plate 4, which hold a non-illustrated door panel or a glass door in a clamping manner by attaching elements 5. Sealing plates and/or damping plates 6 are disposed between the clamping plates 3, 4 and a glass pane to surround the glass panes in a protective manner.
As illustrated in
The cam shaft 7 may be configured as one-part or multipart. In this embodiment, the cam shaft 7 is executed as one-part, wherein the cam 7a is connected to the cam shaft 7 as one-part. (
The roller 22 is rotatably supported at a roller piston 24 by a bolt 23. The roller piston 24 is disposed to be movable in axial direction in an adjusting cylinder 25. A force acts against the roller piston 24 in an axial direction to press the roller 22 against the cam 7a. In this case, the force is essentially exerted in the longitudinal axis of the hinge strip X-X. (
In the zero position of the door, the roller 22 is located in the depression 7b of the cam 7a. As the bearing block 20 is attached to a wall via the attaching plate 21, the clamping plates 3, 4 rotate together with the door about the rotating axis of the hinge strip 1 when opening the door. As the cam shaft 7 is disposed in a torque-proof manner within the first clamping plate 3 via the attaching element 9, the cam shaft 7 rotates within the mounting bracket 28, wherein the cam 7a rolls with its surface on the surface of the rotatably disposed roller 22. In this case, the roller 22, together with the roller piston 24, is pressed against the spring 26 and leaves the depression 7b during this rotary movement. Another latching recess 7c may be disposed at a 90° angle with regard to the depression 7b, such that the door stops at this intermediate position. (
To adjust the zero position of the door once the hinge strip 1 has been installed, the cover caps 29 are removed from both sides of the bearing block 20. Within the bearing block 20, the adjusting cylinder 25 can be adjusted by adjusting elements 30, 31 in the shape of screws or the like. In this case, the adjusting cylinder 25 is adjusted, respectively pivoted by a few angular degrees to deviate from the longitudinal axis X-X of the hinge strip, to compensate for building tolerances.
The adjusting cylinder 25 is disposed in a bore 32 within the bearing block 20 with ample radial play. As the adjusting cylinder 25 is attached transversely, respectively orthogonally with regard to the longitudinal axis of the hinge strip X-X by adjusting elements 30, 31, it is no longer movable in axial direction. The action of adjusting the roller 22 via the adjusting cylinder 25 is orthogonal to the spring plane, such that the adjustment of the roller 22 causes a rotation of the cam shaft 7 and thus of the zero position of the hinge strip 1. The axial movement the roller 22 due to the rotation of the cam 7a is carried out within the adjusting cylinder 25 by the roller piston 24. In this case, the roller piston 24 with the roller 22, which is rotatably disposed on one side, and with the spring 26, disposed on the other side, is axially movable and guided within the adjusting cylinder 25.
To substantially guarantee an adjustment of the adjusting cylinder 25 as precise as possible within the bore 32, the adjusting elements 30, 31 are disposed in axial longitudinal extension of the adjusting cylinder, if possible at the height of the roller 22 at the bearing block 20, such that, the best possible guidance of the roller 22 in the bearing block 20 is achieved as well.
Depending on the radial play between the adjusting cylinder 25 and the bore 32 and depending on the length of the adjusting cylinder 25, the roller piston 24 and the bore 32, a pivoting of the adjusting cylinder 25 within the bearing block 20 can be carried out, depending on the execution, by deviating between ±0° to 15° from the longitudinal axis of the hinge strip X-X.
Thus, while there have shown and described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
