Abstract

The utility model discloses an elevator car wall structure. The elevator car wall structure comprises a wall and a sheet of material having a layered structure. The layered structure comprises a resin layer arranged to attach the sheet of material to the wall and a cushioning layer secured to the resin layer such that the resin layer is located between the wall and the cushioning layer.

Description

Elevator car wall structure

technical field

The utility model relates to an elevator car wall structure, which comprises a wall.

Background technique

There may be a need to reinforce or strengthen the walls of the elevator car. Currently, the car walls are reinforced by metal reinforcement plates, which are glued or welded to the walls.

A problem with known stiffeners is that their flatness quality is not always high enough and there may be gaps between the car wall and the stiffener.

Utility model content

Viewed from a first aspect, there may be provided an elevator car wall structure comprising a sheet of material having a layered structure comprising a resin layer and a cushioning layer, the resin layer being arranged to attach the material sheet to the wall, the cushioning layer Fastened to the resin layer such that the resin layer is located between the wall and the cushioning layer.

Thus, an easy-to-manufacture structure with good flatness on the car wall and low weight can be achieved.

An elevator car wall structure and a method for manufacturing an elevator car wall structure are characterized by what is stated in the characterizing parts of the independent claims. Some other embodiments are characterized by what is stated in the other claims. Embodiments of the utility model are also disclosed in the specification and drawings of this patent application. The inventive content of the patent application may also be defined in other ways than defined in the appended claims. The content of the invention may also be formed by several individual inventions, especially if the invention is examined in terms of expressed or implied sub-tasks or in view of the benefits or groups of benefits obtained. Some definitions contained in the following claims may not be necessary in view of individual inventive concepts. Features of different embodiments of the invention may be applied to other embodiments within the scope of the basic inventive concept.

In one embodiment, the resin includes a thermosetting resin. The advantage is that the resin cures quickly.

In one embodiment, the resin includes epoxy. The advantage is that very good mechanical properties of the material sheet can be achieved.

In one embodiment, the cushioning layer includes an elastomer. The advantage is that the buffer layer can have good damping properties and thus the NVH (noise, vibration and harshness) properties of the car can be improved.

In one embodiment, the cushioning layer includes rubber. The advantage is that the buffer layer can have very good damping properties.

In one embodiment, the cushioning layer includes a fibrous material. The advantage is that an elevator car wall structure with good stiffness and resistance to bending can be achieved.

detailed description

FIG. 1 is a schematic cross-sectional view of an elevator car wall structure 1 . The elevator car wall structure comprises a wall 2 and a material sheet 3 having a layered structure. The layered structure of the sheet of material 3 comprises a resin layer 4 arranged to attach the sheet of material 3 to the wall 1 and a cushioning layer 5 fastened to the resin layer 4 . The sheet of material 3 is arranged such that the resin layer 4 is located between the wall 2 and the buffer layer 5 . In one embodiment, the sheet of material 3 is non-expandable. The term "non-expandable" means that the layer of resin 4 is not meant to fill voids or deform other layers of the sheet of material 3 by swelling during the curing phase of the resin.

The wall 2 may be, for example, an inner wall of an elevator car, a ceiling, a car door panel, a landing door panel or a floor. The material of the wall 2 is usually metal, such as steel or composite material, optionally coated with a coating.

Resins include thermosetting resins. In an embodiment, the resin includes epoxy. The resin may be mixed with one or more additives or functional agents such as fillers and flame retardants.

According to one aspect, the cushioning layer 5 comprises an elastomer. In an embodiment, the cushioning layer 5 comprises rubber.

According to another aspect, the buffer layer 5 comprises a fibrous material, such as glass fibres, carbon fibres, cellulose fibres, polymer fibres, ceramic fibres, or the like.

The elevator car wall structure 1 can be manufactured as described below in this description.

Figure 2 is a schematic illustration of a method for manufacturing an elevator car wall structure.

The method comprises providing a car wall 1 and manufacturing a sheet of material 3 separately from the wall 1 (both shown in Figure 1). The sheet of material 3 has a layered structure as described earlier in this specification.

In an embodiment, the sheet of material 3 is a strip of material detached from a larger entity of material, such as a spool.

The sheet of material 3 is formed 100 into the desired shape before being attached to the wall. In an embodiment, forming 100 includes cutting.

After forming 100 the sheet of material 3 is attached 200 to the wall 1 such that the resin layer of the sheet of material 3 is located between the wall 1 and the cushioning layer 5 of the sheet of material 3 .

The attachment of the sheet of material 3 to the wall 2 is done in a curing step 300 by curing the resin layer 4 at an elevated temperature.

In an embodiment, the curing takes place during the painting work of the wall structure 1 , wherein at least a part of the painting is carried out at a high curing temperature.

Finally, the car wall 1 is completed in a finishing step 400 . This may include, for example, surface finishing, polishing, and the like.

The invention is not limited only to the embodiments described above, but many variations are possible within the scope of the inventive concept defined by the appended claims. Properties of different embodiments and applications may be used in combination with or substituted for properties of another embodiment or application within the scope of the inventive concept.

The drawings and related descriptions are only intended to illustrate the concept of the present utility model. The invention can be varied in detail within the scope of the inventive idea defined in the appended claims.
