Description

The present invention relates to a hinge for a car operating unit, a car operating unit having such a hinge, and a method for opening a car operating unit mounted in an elevator car.

In elevator cars cabin control units are usually attached to side walls of the elevator car. Such cabin control units serve for the input of a destination floor by the passenger, as well as the display of information, such as a designation of a floor on which the elevator car is currently located.

The cabin control unit is connected to switching and safety circuits of the elevator installation via cable connections. During service work on the elevator installation, it may be necessary to open the cabin control unit in order to gain access to the interior of the cabin control unit.

For aesthetic reasons and to protect against vandalism, it is desirable for the car operating unit to be arranged in an overlapping manner with elements of the side wall of the elevator car. However, such an overlapping arrangement does not allow the cab control unit to be easily hinged because the overlapping elements of the cab control unit are engaged by overlapped cabin wall elements.

It is therefore an object of this invention to provide a hinge with which an overlapping cab service unit can be opened. The hinge should be inexpensive to manufacture and save space in the cabin control unit be integrated.

This object is achieved by a hinge, in particular for the rotatable mounting of a cabin control unit on a cabin side wall. The hinge includes a first hinge member for attachment to a first member having a first guide member. The hinge further includes a second hinge member for attachment to a second member. The hinge further comprises a third hinge element with a second guide element which can be guided in the first guide element of the first hinge element. The second hinge element and the third hinge element are rotatably connected to each other and thereby form a joint. The third hinge element and the first hinge element are mutually displaceable, so that the first element and the second element are rotatably and slidably connected to each other.

In a preferred embodiment, the first guide element or the second guide element is designed as a substantially U-shaped guide slot, and the respective other guide element is designed as a feasible in the guide slot bolt.

The invention further provides a cab control unit having at least two hinges as described above. The at least two hinges are preferably arranged on the cabin control unit, which is arranged in an installed state overlapping by fastening elements of the side wall.

The invention provides a method for opening a wall mounted on a side wall of an elevator car Cabin control unit available. The method comprises, in a first step, a displacement of the cabin control unit in the horizontal direction from a center of the cabin control unit to a side wall of the cabin control unit, on which hinges are arranged. The method comprises, in a second step, rotating the cabin control unit so that a content of the cabin control unit is made accessible.

In an advantageous embodiment, the cabin control unit is raised in the vertical direction before being moved, and the cabin control unit is lowered in the vertical direction after being moved.

In FIG. 1 an elevator car is shown in a spatial representation. The elevator car has side walls 2, a ceiling 4 and a bottom 3. In a side wall 2, a car door 5 is arranged. If the elevator car is located on a floor, passengers can get out of the cabin with the car door 5 open through a shaft opening 6. Usually, a shaft door (not shown), which can be moved synchronously with the car door 5, is arranged on each floor.

On a side wall 2, a cab control unit 1 is attached. The cabin control unit 1 can basically be attached to each side wall 2. The cabin control unit 1 is connected to switching and safety circuits (not shown) of the elevator system.

The cabin control unit 1 has a display 7 and controls 8. The display 7 is adapted to present information to the passenger, such as a designation of a floor on which the elevator car is currently located. The controls 8 are used, for example, the input of a destination floor by the passenger, or to trigger an emergency call in an emergency situation.

For maintenance and service work it may be necessary to open the cabin control unit 1 to gain access to internal components of the cabin control unit 1. The cabin control unit 1 has laterally arranged hinges 9, so that the cabin control unit 1 can be opened without being separated from the cabin side wall 2.

In FIG. 1 the hinges 9 are visible. In an alternative preferred embodiment, the hinges 9 are arranged such that they are hidden by the cabin control unit 1.

It can be like in FIG. 1 shown two hinges 9 are arranged on the cab control unit 1, but also only one hinge 9 or more than two hinges 9 can be used.

In the FIGS. 2a to 5c an exemplary embodiment of such a hinge 9 is shown. In the FIGS. 2a . 3a . 4a , and 5a the hinge 9 is shown in a closed position. In the FIGS. 2b . 3b . 4b , and 5b the hinge 9 is in a staggered position shown. In the Figures 2c . 3c . 4c , and 5c the hinge 9 is shown in an open position.

The FIGS. 2a to 2c show the hinge 9 in a spatial representation, while in the FIGS. 4a to 4c and 5a to 5c, the hinge 9 is shown in plan view. In the FIGS. 3a to 3c the hinge is shown in front view.

In the FIGS. 2a to 5c the hinge 9 is fixed to a first element 20 and a second element 21, respectively. In this case, the first element 20 corresponds to a fastening element of the cabin side wall 2 or a component of the cabin side wall 2, and the second element 21 corresponds to a fastening element of the cabin control unit 1 or a component of the cabin control unit 1.

In the FIGS. 5a to 5c the area 21 is shown overlapping. In the FIGS. 2a to 4c the area 21 is shown non-overlapping.

In the following, to explain the inventive hinge 9 on the FIGS. 2a to 5c Referenced.

The hinge 9 consists of three hinge elements: a first hinge element 10, a second hinge element 11 and a third hinge element 12. The third hinge element 12 is connected to both the first hinge element 10 and the second hinge element 11. The second hinge element 11 and the third hinge element 12 together form a rotatable joint. The first hinge element 10 and the third hinge element 12 are slidably connected together. Both the first hinge element 10 as well as the third hinge element 12 have guide elements 15, 16, which the direction and the extent of a displacement of these hinge elements 10, 12 define each other.

Due to the three-part arrangement of the hinge 9, the hinge 9 in an installed state (such as in Figure 3c not shown), but it can be the two elements 20, 21, which are interconnected by the hinge 9, are moved horizontally against each other.

The second hinge element 11 is connected by a pin 13 to the third hinge element 12. These two hinge elements 11, 12 form the hinge of the hinge 9. The second hinge element 11 is mounted on a second element 21, for example by two screws. The third hinge element 12 is not mounted on any element but connects the second hinge element 11 to the first hinge element 10.

The first hinge element 10 and the third hinge element 12 each have a guide element 15, 16, which cooperate. In a preferred embodiment, the first guide element 15 is designed as a bolt, which is arranged on the third hinge element 12. The second guide element 16 is preferably designed as a guide slot, which is arranged in the first hinge element 10. The bolt is slidably received in the guide slot, so that the first and the third hinge element 10, 13 are slidably connected together.

The guide slot defines a direction and extent of a sliding movement between the first and third hinge members 10, 12. In a preferred embodiment, the guide slot is U-shaped. In a built-in state (such as in Figure 3c In this case, two sections of the guide slot are arranged substantially vertically, and a section which connects the two vertical sections is arranged substantially horizontally. The horizontal portion serves for the horizontal sliding movement between the first and the third hinge element 10, 12 and thus the horizontal sliding movement of the hinge 9 and thus the connected by the hinge 9 elements 20, 21. A length of this horizontal portion gives the maximum possible horizontal displacement movement of the Hinge 9 before. The two vertical sections of the guide slot serve to lock the hinge 9 in two positions: in a closed position and in a staggered position. In the locked state, the hinge 9 is secured against horizontal displacement.

In an alternative embodiment, the guide slot is also U-shaped, however, the portion between the two vertical sections is not horizontal but inclined. As a result, for example, the second element 21 must be raised or lowered when moving the hinge 9, depending on the orientation of the inclination of the guide slot. This may be desirable, for example, to complicate the displacement and thus the subsequent opening of the hinge 9.

In a further alternative embodiment, the guide slot has more than two vertical sections. An M-shaped or W-shaped guide slot has an additional vertical portion between the two marginal vertical sections. Thereby, the hinge 9 can be locked in addition to the closed and staggered position in a half offset position.

The guide slot can be adapted to a purpose of use of the hinge 9 by adjusting the number of vertical sections and the inclination of the substantially horizontal section. This results in many variants, which will not be discussed further.

In the closed position and in the open position, the hinge 9 is in principle rotatable. However, if, for example, the second element 21 is arranged overlapping the first element 20 (see FIG FIGS. 5a to 5c ), then the hinge 9 is only in the staggered position ( FIG. 5b ) rotatable. In the closed position ( FIG. 5a ), the hinge 9 is not rotatable because the overlapping element 21 is present at the overlapped element 20 and thus prevents a rotational movement of the hinge 9.

The first hinge element 10 can be fastened, for example, with screws on the first element 20. Preferably, screws are provided above and below the guide slot.

In an alternative embodiment, the third hinge element 12 has the guide slot, and the first hinge element 10 has the bolt. Other embodiments of guide elements 15, 16 are also conceivable, for example rollers and roller guides or sliding shoes and sliding shoe guides.

In an installed state, the hinge 9 rotatably and slidably connects the first member 20 and the second member 21 with each other. In one exemplary embodiment, the first element 20 is a fastening element on the cabin side wall 2 or a component of the cabin side wall 2, and the second element 21 is a fastening element on the cabin operating unit 1 or a component of the car Cabin control unit 1. It is possible to attach either the first or the second hinge element 10, 11 to the cabin control unit 1 and the other on the cabin side wall 2. It only needs to be ensured that the cabin control unit 1 is moved horizontally in the desired direction can be. In this case, for example, a horizontal displacement parallel to the side wall 2 (ie, along the side wall 2) or a horizontal displacement perpendicular to the side wall 2 (ie in a passenger compartment into it) come into question.

Under cabin control unit 1 in the context of this invention, only components understood that are moved or rotated when opening. In a first embodiment, the car control unit 1 includes only a front panel with the display 7 and the controls 8. In a second embodiment, the car control unit 1 also includes other electronic and / or mechanical components which are connected to the front panel. The cab control unit 1 can also be designed as a box, which can be moved and rotated as a whole.

The cabin control unit 1 is preferably connected to the cabin side wall 2 by at least two hinges 9. In an alternative embodiment, the cabin control unit 1 is connected to the cabin side wall 2 only by a hinge 9.

• Zunächst befinden sich die mindestens zwei Scharniere 9 in der geschlossenen Position (Figuren 2a, 3a, 4a und 5a). Dann wird die Kabinenbedieneinheit 1 angehoben, wodurch sich die Kabinenbedieneinheit 1 parallel zur Kabinenseitenwand 2 in vertikaler Richtung nach oben verschiebt. Dabei verschiebt sich der Bolzen des dritten Scharnierelements 12 im U-förmigen Führungsschlitz entlang des ersten vertikalen Abschnittes, bis der Bolzen in einer Ecke zwischen dem ersten vertikalen Abschnitt und dem horizontalen Abschnitt ist. Dieses Anheben wird durch eine Länge des ersten vertikalen Abschnittes begrenzt.

To open the cabin control unit 1, the following procedure is used in an advantageous exemplary embodiment:

• First, the at least two hinges 9 are in the closed position (FIG. FIGS. 2a . 3a . 4a and 5a ). Then, the car operating unit 1 is raised, whereby the car operating unit 1 shifts in a vertical direction parallel to the car side wall 2 in the upward direction. It shifts the bolt of the third hinge member 12 in the U-shaped guide slot along the first vertical portion until the bolt is in a corner between the first vertical portion and the horizontal portion. This lifting is limited by a length of the first vertical section.

After complete lifting, i. When the bolt is at a level of the horizontal portion of the guide slot, the car operating unit 1 is shifted horizontally and parallel to the cabin side wall 2. This displacement movement is limited by a length of the horizontal portion of the guide slot.

After complete displacement movement, ie when the bolt has passed through the entire length of the horizontal section and is now in a vertical line with the second vertical section of the guide slot, the car operating unit 1 is lowered. The bolt passes through the second vertical section of the guide slot. This lowering movement is limited by a length of the second vertical section. When the bolt is at a lower end of the second vertical portion, the car operating unit 1 is in the staggered position (FIG. FIGS. 2b . 3b . 4b and 5b ). In this staggered position, the hinges 9 are again locked (as in the closed position) and the bolts of the hinges hang in the second vertical sections of the guide slots of the first hinge element 10.

After the shifted position is reached, the car operating unit 1 is turned away from the cabin side wall 2 into the passenger compartment of the elevator car. During this rotational movement, the second and the third hinge element 11, 12 rotate relative to each other. After successful Rotation are the hinges 9 in an open position ( Figures 2c . 3c . 4c and 5c ).

By performing the steps described above in reverse order, the car operating unit 1 can be returned from the open position to the closed position via the offset position.

Characterized in that the bolts of the third hinge elements 12 hang in both the closed and in the displaced position by the weight of the cab control unit 1 in the first and second vertical sections of the guide slots of the first hinge elements 10, the hinges 9 in both or all positions (also in the open position) increased stability. In both or all positions, the cabin control unit 1 is protected against vertical displacement.

The hinge 9 may connect other components with walls or the like instead of the cab control unit 1. The hinge 9 is preferably used where there is little room for a hinge 9, and where, however, can not be guaranteed on the functions rotating, moving horizontally, and locking.
