Description

Field of technique [0001] The following embodiments refer to a car for a lift system, comprising an interior space with a roof that delimits the interior space in an upper direction, wherein the roof has an opening and at least one first cover that can be opened to selectively open or close the opening and a latch to secure the first cover to at least one first fixed or fixable counterelement of the car when the opening is closed. [0002] In addition, the following embodiments refer to an elevator system comprising at least one elevator shaft with multiple landing positions and at least one such car. Background of the technique [0003] Elevator systems for transporting people and/or goods are an integral part of modern residential and commercial buildings. A typical elevator system comprises one or more elevator shafts, in each of which one or more cars are moved between landing positions by means of drives, such as suspension drives or linear drives. [0004] In such elevator systems, it is known to provide an opening in the roof of a car that can be respectively covered by a cover, which serves, for example, for the maintenance of the elevator system and/or the evacuation of people from the car in an emergency situation. [0005] In particular, in the case of elevator systems with suspension-type drives, designs are known without the usual machine room provided above the elevator shaft. For this, the car drive devices are arranged at the top of the elevator shaft. From there, maintenance of such a drive device is known to be carried out from a maintenance platform inside, where the maintenance platform is stored in the opening area in the ceiling and is unfolded or extended from there during or after opening the cover for installation inside. An elevator system of this type is known, for example, from document EP 3 530 603 A1. [0006] The disadvantage of the elevator system described above is that it generally takes a long time to open and close the first cover or covers. In addition, closing mechanisms known until now often do not provide a secure closure. [0007] It is known, from document EP 2 123 586 A1, a car with an inner roof plate and an outer roof plate, wherein a rescue hatch is disposed in the outer roof plate and an inspection hatch, opposite the rescue hatch, is disposed in the inner roof plate. A cover for opening and closing the rescue hatch is disposed in the outer roof plate, and a cover for opening and closing the inspection hatch is disposed in the inner roof plate. The inner cover has a rotating angle that locks the inner cover to the inner roof plate in one position and releases the inner cover in another position. Description - Technical Solution [0008] Based on this situation, the objective in question is to allow for simple and safe opening and closing of a car's hood (or hoods), as described above. [0009] The objective in question is resolved by the characteristics of the independent claims. Advantageous embodiments are specified in the dependent claims, in the description and in the drawings. To the extent technically feasible, the teachings of the dependent claims may be arbitrarily combined with the teachings of the main and dependent claims. [0010] In particular, the object is solved by a car for a lift system, comprising an interior space with a roof that delimits the interior space in an upper direction, wherein the roof has an opening and at least one first cover, which can be opened, to selectively open or close the opening, and a latch to secure the first cover to at least one first fixed or fixable counterelement of the car when the opening is closed, wherein the latch has: a rotating bolt disposed in the first cover, a bolt receptacle disposed in the first counterelement, with at least one first protrusion to engage under the bolt when the first cover is closed, wherein the bolt is subjected to a force to a rotational position overlapping the first protrusion, and a tool engagement facing the interior space, to rotate the bolt against the application of force, out of overlap with the first protrusion, wherein the bolt receptacle has an adjustment contour on a lower side, so that the bolt is rotated out of overlap with the first The protrusion is pressed against the underside of the bolt receptacle through the adjustment contour, and the first protrusion may pass. [0011] Advantageous aspects are explained below and preferred modified modalities are described further on. Explanations, particularly regarding advantages and definitions of features, are essentially descriptive and preferential examples, but not limiting. If an explanation is limiting, this will be explicitly mentioned. [0012] When ordinal numbers, such as “first,” “second,” etc., are used, for example, to designate a component, an element, a process step, or a process action, these ordinal numbers are intended purely for differentiation in designation and do not indicate any dependency or sequence.
