The present invention concerns an elevator monitoring unit for an elevator hoistway access opening (termination) at a floor.
An elevator monitoring unit comprises the necessary electrical sub-assemblies for the control and regulation of the elevator and particularly of the elevator drive. Furthermore, ordinary elevator monitoring units contain today the interfaces and input modules necessary for maintenance and diagnostics. In case of elevators with no motor room, this elevator monitoring unit is placed advantageously within the area of the elevator hoistway termination.
An elevator hoistway lock enables access from the floor to the car. It consists essentially of movable doors and a door frame fastened in the building, which among other things exhibits at least two vertical door posts.
The installation of electrical devices (or an elevator monitoring unit) in the elevator hoistway termination or in the door post is well-known from the Soviet patent document SU 1 654 214. These solutions were refined with the European patent specification EP 0680921 and the Japanese patent specification JP 03018569. These solutions swivel thereby the door post, or respectively the relevant door post part around a vertical axle to the side.
A disadvantage of this solution is that caused by the swivelling movement a large aperture area is necessary, or the access to the controlling equipment is difficult.
The requisite maintenance works in the elevator monitoring unit cause an unrestricted as possible access to all sub-assembly elements. This causes an accordingly large aperture, which, in the case of the well-known solutions, can be realized only by a large aperture angle with the associated space requirement.
The present invention underlies the task to suggest an arrangement of the elevator monitoring unit in the hoistway termination, which bypasses the described disadvantages and in particular makes possible a special space saving arrangement of the elevator monitoring unit in the hoistway termination. The placement of the elevator monitoring unit should be possible on each floor, without any change of the installation dimension. The solution should be able to be managed with proven components and procedures of the elevator construction. The production should take place economically and at low costs. The access to the elevator monitoring unit should be safe and simply possible for authorized persons, however it should be able to be protected from the access by unauthorized ones.
The present invention concerns an elevator monitoring unit built into a door post of an elevator hoistway termination comprising: a door post element; an elevator monitoring unit arranged on the door post element; and means for mounting the door post element on an elevator hoistway termination door post, the means for mounting enabling the door post element to be one of parallel-shifted horizontally and tilted around a horizontal axis relative to the door post between a closed position and an open position. In the closed position, the elevator monitoring unit is inside the door post. In the open position, the elevator monitoring unit is accessible for maintenance.
The above, as well as other advantages of the present invention, will become readily apparent to those skilled in the art from the following detailed description of a preferred embodiment when considered in the light of the accompanying drawings in which:

The represented solution permits an economic production. The solution permits a simple, safe and fast access to the elevator monitoring unit 10 for the purpose of maintenance, repair, and diagnostics or for special purposes. Special purposes are all interventions as for example fire-brigade operation, emergency evacuation or electric network controls.
The installation of the elevator monitoring unit 10 can, in case of need, be divided between several door post elements 6 or arranged at other places, if due to the space requirement, the accessibility, or the functional separation of the elevator monitoring unit 10, this is judged as meaningful. Parts of the elevator monitoring unit 10, for which the fast access is of subordinated importance, are placed in the rule according to their function. So, for example, the transformer, belonging to the elevator driving gear, can be placed with the elevator drive, and only the command module is located on the door post element 6.
In a preferred variant shown in
When opening, the door post element 6 is moved together with the mounted elevator monitoring unit 10 according to the lever geometry (8a, 8b) parallel outwards and downwards, until the movement is delimited by the floor 4 or by an integrated stop motion device 11 (
The door post element 6 is structurally in such a manner arranged that, in the opened position of the door post element 6, the components of the elevator monitoring unit 10 are accessible from two sides. This execution improves the accessibility for the necessary interventions.
In another variant, the parallelogram described above is replaced by a tilting mechanism 12, whereby the door post element 6 is mounted at the bottom in a pivoting manner (
A further variant has an opening mechanism that results in the door post element 6 being self-locking. This is achieved, for example, as the door post element 6 is held in its closed position by means of a locking spring 13 (
In another variant, a floor indicator board 7 is integrated directly into the door post element 6.
The execution of the elevator monitoring unit 10 is in such a preferred manner arranged that the dimension given by the entrance height of the hoistway termination is used and thus, the elevator monitoring unit 10 can be arranged to a large extent completely within the door post 5. In the example shown, the height of the door post element 6 amounts to approximately 1.3 m with a width of approximately 0.12 m. Through this space-saving arrangement, an optimal utilization of the building area in the door post 5 is reached, whereby a flexible arrangement of the elevator monitoring unit 10 is made possible independently of the door post dimensions at each floor. The position requirement for the individual floor is independent from the arrangement of the elevator monitoring unit 10.
In the
By the attachment of a fireproof assembling box in the door post 5, the necessary fire-protective class of the concerned hoistway termination can be ensured without restriction.
With knowledge of the present invention, the man skilled in the art can change the set sizes and arrangements at will. For example, the space requirement shown can appropriately be increased or made smaller by 0.15 m.
In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
