ELEVATOR CABIN

Description

[0001] The invention relates to an elevator car for an elevator. Elevators for transporting people and goods contain elevator cars that can move up and down in an elevator shaft. The cars can be moved by means of a drive unit via suspension elements, for example, in the form of cables or belts. Typically, the elevator car has a cuboid body comprising a floor, doors, walls (side walls, rear wall), and ceiling. Passengers remain inside the cabin body during the ride. Handrails are often provided in the cabins, allowing passengers, such as elderly people, to hold onto them and thus ensuring their comfort and sense of security.

[0002] From CN 206814229 U a handrail has become known which can be used as a backrest.

[0003] However, the handrail is designed in a cushion-like shape and is characterized by a compact design.

[0004] WO 2017 / 033038 A1 shows a handrail which, in cross-section, is hook-shaped and directed upwards and is configured to provide structural stability to the wall of the elevator car.

[0005] It is an object of the present invention to provide an elevator car with an interior handrail, characterized by improved comfort. This object is achieved according to the invention with an elevator car having the features of claim 1. The elevator car comprises interior walls forming the passenger and / or goods compartments. The cabin walls can consist of two opposing side walls and a rear wall connecting them. The handrail's design as a backrest for passengers improves comfort. Passengers can lean comfortably against the handrail during a car ride. This comfortable position is particularly useful if passengers are trapped in the car during an unplanned, prolonged stop.

[0006] The backrest preferably defines a leaning area for the buttocks and / or lower back of a passenger. The handrail can be designed for a model person. Depending on the geographical area of ​​application and other demographic factors, this model person could, for example, be an adult with a height of, say, 175 cm.

[0007] From an ergonomic point of view, it is advantageous and particularly pleasant for the sense of comfort if the handrail has a leaning surface with a height of at least 15 cm, preferably at least 20 cm.

[0008] The handrail designed as a backrest for passengers can include a leaning surface that is substantially inclined to the adjacent vertical cabin wall. From an ergonomic point of view, it is particularly advantageous if the handrail designed as a backrest for passengers is inclined relative to the vertical with respect to its leaning surface, the angle of inclination of the leaning surface relative to the vertical being between 5° and 20°, and preferably between 5° and 15°. With such an inclined handrail, the leaning surface is directed slightly upwards for comfortable leaning. In other words, the surface normal of the leaning surface points upwards. This handrail is characterized by particularly favorable ergonomics.

[0009] The leaning surface can have a constant angle of inclination over essentially the entire height of the handrail. However, it is also conceivable that the leaning surface has a varying angle of inclination relative to the vertical along its height. For example, the handrail can have an angle of inclination relative to the vertical at its upper end, or at the end facing the upper edge, that is greater than the angle of inclination of the handrail at its lower end.

[0010] The handrail can have a flat outer shape in its vertical cross-section with respect to its support surface.

[0011] If the elevator car comprises two cabin walls joined at a corner, it can be advantageous for the handrail spanning the corner to have an L-shape when viewed from above. The L-shaped handrail is adapted to the corner and allows for comfortable leaning against it in the corner area. The L-shaped handrail, which spans two side walls, is preferably formed in one piece. Alternatively, it would also be conceivable for the handrail to have a U-shape when viewed from above, in which case the handrail spans three cabin walls.

[0012] It is advantageous if the L-shaped handrail has two handrail sections, each assigned to a cabin wall and extending in a horizontal direction, with one of the handrail sections being shorter than the other handrail section.

[0013] It can be particularly advantageous if the L-shaped handrail for forming a single seat in the corner has a short handrail section extending in a horizontal direction with a side length measured in the horizontal direction of a maximum of 50 cm and preferably a maximum of 40 cm.

[0014] For improved comfort, it can be advantageous if the handrail, at least in the area of ​​the leaning surface, is covered or upholstered with a textile material. Textile materials can include woven, knitted, braided, sewn, nonwoven fabrics, and felts. Leather or imitation leather are also conceivable alternatives to textile materials.

[0015] Furthermore, the handrail, designed as a backrest for passengers, can have padding, for example made of foam material. This foam material could be positioned between the textile material that forms the outer surface and a support structure for the handrail.

[0016] If the elevator car includes a cabin wall to which the handrail is attached, it can further improve comfort if at least one section or segment of the cabin wall above the handrail is covered with a textile material to create a backrest for passengers. This provides a comfortable place to lean against the upper back. The cabin wall can be completely covered with textile material. Alternatively, the cabin wall can be divided vertically into two or more wall segments. A lower wall segment, located below the handrail, can be left uncovered. An upper wall segment above this lower segment can be covered with textile material. This upper, textile-covered wall segment can extend to the cabin ceiling.It is of course also conceivable to provide a non-textile wall segment above the upper textile wall segment.

[0017] The handrail can have a shell-like profile to provide a support structure. This profile can be made of metallic materials, for example, formed from one or more metal sheets. Alternatively, the profile could be injection-molded from plastic. The profile can be covered or upholstered with textile material.

[0018] Further individual features and advantages of the invention will become apparent from the following description of exemplary embodiments and from the drawings. These show: Fig. 1 a highly simplified schematic representation of an elevator cabin according to the invention, Fig. 2 a simplified perspective view of another elevator car, and Fig. 3 a perspective view of a handrail for the in Fig. 2 Elevator cabin shown.

[0019] Fig. 1 Figure 1 shows an elevator car, labeled 1, for elevators. Elevators are used for vertical transport in multi-story buildings. The buildings have elevator shafts in which the elevator car 1 can move up and down to individual floors. The movement of the elevator car 1 is effected by support elements (not shown here) to which the elevator car 1 is attached; these support elements can be one or more suspension cables or belts. The elevator car 1 can, for example, be self-supporting or arranged in a supporting structure, such as a support frame. The in Fig. 1 The elevator car 1 shown here, in a simplified example, has a cuboid-shaped body and comprises a floor 5, walls, and a ceiling. The walls consist of opposing side walls 2 and 3, and a rear wall 4 connecting the side walls. The elevator car 1 also has a door (not shown) that closes off the open front and thus the interior of the elevator car 1.

[0020] A special handrail 7 is attached to the side wall 3. The handrail 7 is characterized by its design as a backrest for passengers. The person can thus lean comfortably against the handrail 7 and in the Fig. 1 The handrail 7 has a backrest surface of a relatively high height. To allow for comfortable positioning of the person, the height H of the handrail 7, designed as a backrest for passengers, is at least 15 cm and preferably at least 20 cm.

[0021] The handrail 7 has an upper edge 9 that forms a gripping area for passengers to hold onto if needed. Furthermore, the handrail 7 has a lower edge 10 that extends downwards to the cabin floor 5 such that the lower edge 10 is less than 60 cm from the cabin floor 5. The distance D of the lower edge 10 to the cabin floor 5 is denoted by D.

[0022] The handrail 7, designed as a backrest for passengers, is evidently inclined with respect to its leaning surface relative to the vertical. The corresponding angle of inclination relative to the vertical of the leaning surface is denoted by α. The angle of inclination α of the slightly upward-facing leaning surface lies between 5° and 20°, and preferably between 5° and 15°.

[0023] Fig. 2 Figure 1 shows a variant of the handrail 7, designed as a backrest for passengers, in which the handrail 7 is arranged in a corner area. The cabin walls 3 and 4 of the elevator car 1 are connected to each other via a corner 6. To bridge the corner 6, the handrail 7 has an L-shape in a plan view. The L-shaped handrail 7 has two handrail sections 11 and 12, each extending horizontally and assigned to a cabin wall 3 and 4, respectively. The handrail section 11 assigned to the rear wall 4, shown here as an example, is shorter than the other handrail section 12. Because the L-shaped handrail 7 has a short handrail section 11 with a side length of a maximum of 50 cm, and preferably a maximum of 40 cm, an advantageous individual seat is provided in the corner. The handrail 7 can be covered or upholstered with a textile material, at least in the area of ​​the backrest 8.Instead of textile materials, non-woven fabrics, leather, imitation leather, or other materials commonly used in seating furniture are of course also conceivable. Besides aesthetic advantages, the textile backrest surface 8 has the benefit that people leaning against it are less likely to slip, which ultimately also has a positive effect on personal safety.

[0024] The cabin walls can be segmented. In Fig. 2 Horizontal dividing lines for defining the segments in cabin walls 3 and 4 are indicated by dashed lines. Cabin wall 3, 4 can be covered with a textile material to form a textile backrest for passengers, at least in the wall segment marked 8 above the handrail 7. Instead of textile materials such as woven, knitted, braided, sewn, nonwoven, and felted fabrics, leather or imitation leather are also conceivable. Any materials commonly used for upholstering furniture can be used to cover or cover the cabin wall.

[0025] Cabin walls 2, 3, and 4 can be constructed in multiple sections, each consisting of a lower wall panel and an upper wall panel. These panels are horizontally butted against each other and can define wall segments. The wall panels can each be made of metal sheets and manufactured from a single sheet blank.

[0026] Constructive details of a handrail designed as a backrest for passengers 7 are made of Fig. 3 Removable. The handrail 7 has a shell-like profile body 13 to provide a support structure for the handrail 7. Reference numeral 14 designates a connection element by which the handrail 7 can be attached to the cabin wall, for example by means of screws. The profile body 13 can be made of sheet metal.
