Description

Handrail of elevator car

Technical Field

The invention relates to an elevator car for an elevator.

Background

An elevator for transporting people and goods comprises an elevator car which can be moved up and down in an elevator shaft. The car can be moved by means of a drive unit via a support means, for example in the form of a support rope or a support belt. Typically, elevator cars have a square car body including a bottom, doors, side walls, a back wall and a top. Passengers stay in the interior space of the car body during car travel. A handrail is generally disposed in the car, and passengers such as the elderly can grip the handrail to ensure their comfort and safety.

Disclosure of Invention

The object of the invention is to provide an elevator car with one or more handrails in the interior space of the car, which can be manufactured easily and inexpensively. According to the invention, this object is achieved by an elevator car having the features of claim 1. The elevator car comprises a car wall forming an interior space for passengers and/or goods. The car walls may be side walls and a back wall. At least one of the car walls may consist of two wall panels joined to each other horizontally. By horizontally joined to each other is meant that the wall panels are not arranged side by side with each other, but on top of each other, whereby the joint areas, i.e. the areas where the wall panels are joined or in contact with each other, extend horizontally. In other words, the wall panels joined to each other horizontally define a horizontal parting line.

The wall panels may be composed of sheet metal, such as sheet steel. In the joining region, one or both of the wall panels for forming the handrail adjoin a web section which projects into the interior space and on which a vertical profile section is molded by means of a fold in order to specify a handle piece for the handrail.

The handrails can extend in the horizontal direction over the entire width of the respective car wall or at least over a partial region of the car wall.

The vertical profile section can be directed upwards from the fold and can also project in the direction of the car roof. The height of the profile section, i.e. the length of the profile section in the vertical direction, may preferably be at least 3cm, particularly preferably at least 5 cm.

The vertical profile section can be a profile section having a straight course in cross section. So that the handrail has a vertical flat outer surface. Alternatively, however, it is also conceivable for the profile section to be provided with a curved shape, in particular with an arc shape.

The wall panels, the web sections adjoining the wall panels, which project into the interior, and the vertical profile sections molded onto the web sections are integral parts of a one-piece component and are connected to one another in one piece. In a particularly advantageous manner, the wall panel, the web section and the profile section are formed from a common or common sheet metal blank.

The wall panel provided for building the handrail can be manufactured easily and in an automated manner by a stamping process and a hemming process. It can be said that the handrail is formed simultaneously when the panels are connected. Thus, a special work step for mounting the armrest to the car wall is no longer required.

To form the handrail, the two wall panels joined to one another can each have a web section. The web sections lie flat against one another and preferably extend parallel to one another in a plane.

The end section can adjoin the vertical profile section, which end section is flanged to form an undercut with respect to the profile section. In this way, a sharp upper end of the web section can be prevented, resulting in an ergonomic grip tab for a handrail, which does not pose a risk of injury.

The horizontally joined wall panels can have a profiled or profiled web section and a profile section, so that together they define a T-shaped cross section. In this way, the armrest is formed, and a child or an older person can grip the armrest from below, if necessary.

It may be particularly advantageous if the armrest comprises a nest around the vertical profile section. The nesting component is used for protection and ergonomics. This virtually eliminates injury from sharp edges. Nesting may also be desirable for aesthetic reasons. The walls joined to each other can be held together with the aid of a sleeve. The insert thus forms a means for connecting the wall panels. In some cases, therefore, additional fastening means, for example in the form of screws, by means of which the wall plates are connected to one another, for example in the region of web sections adjacent to one another, may be dispensed with.

The insert can be C-shaped in cross section. This is particularly true when the web section and the profile section form a "T" shape in cross-section. Such a C-shaped sleeve surrounds the handrail in an advantageous manner and method and is easy to manufacture.

It is particularly advantageous when the insert is made of a synthetic material. Such a sleeve can be produced particularly easily and inexpensively. Another advantage of the synthetic material insert is that it can be adjusted in color and feel as desired according to the requirements of the elevator operator.

In addition, it is advantageous if the wall panels are connected to one another in the region of web sections adjacent to one another by fastening means. The fastening mechanism may be, for example, a detachable connection, such as a bolt connection. Of course, a clamp connection or other type of connection is also possible. For example, an adhesive connection or other fastening mechanism may be provided.

Detailed Description

Fig. 1 shows an elevator car designated 1 for an elevator. Elevators are used for vertical transport in multi-storey buildings. The building has an elevator shaft in which the elevator car 1 can be moved up and down to various floors. The movement of the car 1 is effected, for example, by means of a support means, indicated by 5, on which the car 1 is suspended; the support means 5 can here be one or more load carrying ropes or belts. Of course, the car 1 described in detail below can also be used for other types of equipment. For example, the car 1 supported by the sheave can be supported by the support device at 2: 1 suspension is connected to the counterweight.

The car 1 may be designed to be self-supporting or may be arranged as a support structure (not shown) such as a support frame. The elevator car 1 shown in fig. 1 has in this example a simplified square car and comprises a bottom 3, side walls 2, 2' opposite each other, a rear wall 2 "and a top 4. The car 1 furthermore has a door (not shown) which closes the open front side and thus the interior space 1 of the car. The

car walls

2, 2', 2 "form an interior space 18 for passengers and/or cargo.

The

car walls

2, 2' and 2 "are made up of a plurality of parts and each consists of a lower wall plate 6 and an upper wall plate 7. The individual panels are obviously wall panels joined to one another horizontally. In fig. 1, the corresponding horizontal separation line is visible approximately in the middle of the car wall.

The two

wall panels

6, 7 each consist of sheet metal and can each be produced from a sheet metal blank. The metal plate may be, for example, a common steel plate or a laminated steel plate. The metal sheet may also be coated with a paint or varnish.

As shown in fig. 1, a handrail, indicated by 20, is provided in the region of the side wall 2. The wall plate 6 and the wall plate 7, which are joined to one another horizontally, are designed such that they form the mentioned handrail 20 in the joining region. The opposite side wall 2' may also comprise such a handrail 20. Such a handrail may of course be provided for the side wall 2' forming the rear wall, depending on requirements.

The handrail 20 can be easily manufactured from a sheet metal blank provided for the

wall panels

6, 7 by a sheet metal machining method, in particular a flanging process, in the manner described in detail below. The armrests need not be cost-effectively mounted to the car walls. When assembling the car 1 in which the

wall panels

6, 7 are additionally mounted, the handrail 20 is mounted in the same working step. The following fig. 2 to 8 show different embodiments of handrails 20, which are formed essentially only by the special shaping of the

wall panels

6, 7 and by assembling these to form the car body.

Fig. 2 relates to a particularly simple embodiment in which one of the walls, namely the lower wall 6, is a standard part, while only one of the walls, namely the upper wall 7, is specifically designed. In fig. 2, the lower wall plate 6 is straight in its region facing the upper end of the wall plate 7.

In contrast, the upper panel 7 has a lower end with the following special shaping: a web section 8 projecting into the interior adjoins the wall plate 7, on which a vertical profile section 10 is molded by a flange 17 in order to define a handle piece for a handrail 20. There is thus no sharp upper end on the grip piece, the end section 12 adjoining the profile section 10, which end section is flanged to form an undercut with respect to the profile section 10. The two

wall panels

6, 7 can be attached to a support structure (not shown here) for the car, for example by means of bolts.

In contrast to the first embodiment of fig. 2, in fig. 3 the upper end of the lower wall plate 6 is provided with a web section 9 which extends parallel to the web section 8 of the upper wall plate 7. It is clear that the two

web sections

8 and 9 of the

wall panels

6, 7 which are joined to one another lie flat against one another. Due to the two

web sections

8, 9, the two

wall panels

6, 7 can be easily connected to each other by suitable fastening means; the corresponding fastening mechanism is indicated at 16. The fastening means can be, for example, a screw connection, by means of which the

wall plates

6, 7 can be easily screwed to one another in the region of the

web sections

8, 9 adjoining one another.

Fig. 3a shows a variant of the embodiment according to fig. 3, in which the handle piece for the armrest 20 is formed by the lower wall panel 6. The lower wall 6 has an upwardly directed vertical profile section 11, which vertical profile section 11 adjoins the horizontal web section 9, which vertical profile section specifies a handle piece for a handrail 20.

The handrail 20 shown in figure 4 is similar to that of figure 3, but with the exception of enhanced personnel safety and for good ergonomics when holding the handrail, a grommet 14 is attached to the handrail 20, the grommet surrounding the profiled section 10. The nesting component 14 is preferably made of a synthetic material and may be colored differently according to the customer's needs. In order to securely fasten the sleeve, a contour 15 can be provided in the web section 9, which contour forms a type of locking projection for a corresponding mating piece of the sleeve 14. Of course, the sleeve 14 may be secured in other ways. For example, the sleeve 14 may be glued. Thermal methods are also conceivable in which the insert 14 is integrated into the handrail 20 by shrinking, due to the material of the corresponding synthetic material.

Fig. 5 shows a detailed view of the armrest 20 of fig. 1. The cross-section of the handrail 20 is defined as "T". Each

wall panel

6, 7 has an inwardly directed

horizontal web section

8, 9, a

vertical profile section

10, 11 and an

end section

12, 13, respectively. The armrest 20 is designed symmetrically with respect to a horizontal axis in the joint area. However, in some cases it may also be advantageous to design the upper profile section 10 to be longer than the lower profile section 11. Other sizes or contour shapes are also conceivable.

The armrest 20 according to fig. 6 differs from the previous embodiment only in that the armrest 20 is additionally equipped with a telescope 14. Owing to such a sleeve 14, undercuts at the upper and lower ends of the

profile sections

10, 11 can even be dispensed with. Such an embodiment variant is shown in fig. 7.

However, by appropriately designing the end regions of the

vertical profile sections

10 and 11, the sleeves can also be dispensed with without sacrificing high safety requirements. The

end sections

12, 13 adjoining the

respective profile section

10, 11 are curved in cross section. Such an embodiment variant is shown in fig. 8.
