Description

Pivoting arrangement, roof element and elevator

Technical Field

The object of the invention is a pivoting arrangement, a roof element and an elevator, more particularly a pivoting arrangement for an emergency exit hatch of an elevator applicable to a roof element in an elevator transporting people and/or goods.

Background

The elevator car is conventionally formed to comprise a load-bearing frame structure, i.e. a car sling, comprising a lower horizontal beam system and an upper horizontal beam system, as well as a first-side vertical beam system and a second-side vertical beam system, said beam systems being connected to each other such that they form a closed loop, inside which is included the interior of a car box fixed to the beam systems, which can receive goods and/or passengers for transporting them inside the elevator car.

The elevator car of the elevator can also be mounted inside a car sling consisting of a top element, a bottom element and side elements, i.e. vertical elements. The car and car sling can be integrated into each other, if desired.

The outer surface of the roof of the elevator car is usually formed by plates which are firmly and rigidly supported on the upper horizontal beam system. According to the prior art, there is a separate roof panel in the elevator car below the upper horizontal beam system, which panel forms the outer surface.

According to national and international regulations, the structure connected to the outer surface of the roof of an elevator car is an emergency exit hatch, which is usually hinged to the roof structure by means of a fixed hinge. The roof structure of an elevator with an emergency exit hatch provided with a fixed hinge is awkward and expensive to manufacture and requires separate fixing means for installing the roof hatch and special tools for fixing the hinge. Furthermore, a separate locking device is required to lock the emergency exit hatch, which again increases the number of parts required, thereby increasing the manufacturing costs, installation costs, and maintenance costs of the product.

The mounting of the fixed hinge at the emergency exit hatch also substantially limits the opening direction of the hatch. Changing back the opening direction of the emergency exit hatch provided with a fixed hinge is awkward and expensive, requires the installer to have many special tools and is sometimes even impossible due to the roof structure of the elevator.

In summary, one of the problems of the solutions according to the prior art is that, for example, the solution described in document GB2116601A may not be considered to be an optimal structure. More particularly, the roof structure of an elevator car is not fully optimized as a solid from the point of view of the space availability and complexity of the structure. All the necessary factors are not taken into account simultaneously to a sufficient extent, and more particularly the number of parts of the roof structure of the elevator and its manufacturing technique are not yet optimal. Thus, the simplification of the roof structure and the reduction of the number of components directly affect the manufacturing costs, the installation costs and the maintenance costs, and also increase the reliability of the elevator and reduce the structural weight of the elevator, thereby reducing the energy consumption and reducing the running costs. The structural weight of the elevator, which can be reduced, is important per gram and thus energy consumption.
