CAR

The invention relates to an elevator car as defined in the preamble of claim 1.

5

Conventionally, a car frame, i.e. a rigid, substantially rectangular frame with sliding guides and grips, to which the ropes are also attached or supported, serves as the supporting structure of the elevator car. The basket 10 itself is then built inside the rigid basket frame, i.e. the floor is built on the lower support of the basket frame, the walls are built inside the vertical beams and the roof of the basket is below the upper support of the basket frame. Thus, the load-bearing and rigid element of the entire structure is a rack-15 hys, whereby the rack itself can be made of relatively light materials.

A disadvantage of the prior art is the complexity of the structure of the elevator car and the basket frame. The basket frame is relatively expensive to manufacture, requires a lot of raw material and is slow and difficult to install in the elevator shaft. In addition, the basket frame requires a large amount of space in the elevator shaft, so that the basket frame necessitates the construction of relatively large elevator shafts or, alternatively, the construction of relatively small elevator frames.

A self-supporting elevator car with load-bearing walls is disclosed in DE-A-2523064. The wall structure as a whole acts as a load-bearing element for the load and the adhesive force. In this case, the entire wall of the elevator car must be dimensioned to withstand the forces exerted on it in the event of travel, braking and braking. Here is the announcement ·· 1. The solution described in the slip also does not distinguish between the 35 Telia elevator frame and the elevator car connected to it, · · ·: V but the entire elevator car acts as a load-bearing structure. Therefore, the size of the bodywork and its parts must be dimensioned according to it. 1 · 1 · 107250 2. The upper beam to which the hoisting ropes are attached is bolted to the basket. Guide shoes and Velcro fasteners: fixed on the one hand to the lower edge of the body and on the other to the upper beam, whereupon the body 5 cannot be considered to act as a body frame, but the forces are applied through the mounting bolts between the upper beam and the body and body.

French application FR-A-1371974 discloses an elevator car having sidewalls consisting of a plurality of panels, each side wall comprising two panels with a central panel in the middle. This center plate is U-shaped, so the plates on each side are bent to fit the U-shaped center-15 plate. This belt disc structure formed by the center plate increases the rigidity of the walls of the body and allows the support members to be secured. The joints of these plates form protrusions on the side wall. The floor and ceiling of this elevator car have walls in the same way! 20 three plates with a U-shaped spindle in the center; vy.

The object of the invention is to eliminate the above-mentioned disadvantages. In particular, the object of the invention is to provide <: <25 da bring out a new elevator car design that lets you! the total cost of the elevator, ie raw material, manufacturing and installation costs, is reduced. It is a further object of the invention to enable more efficient use of the space delimited by the elevator shaft.

In particular, the elevator car according to the invention is characterized in what is disclosed in the characterizing part of claim 1.

35 * · t; The elevator car according to the invention comprises a carrier frame acting as a load-bearing structure and having a basket edge; [107250 3 vertical beams, top and bottom supports with knives, and a basket with wall elements, ceiling and floor. According to the invention, the vertical beams of the basket frame form part of the wall elements. Thus, the invention is based on the realization that the basket frame does not need to be constructed as a completely separate and exterior structure from the basket, but at least the vertical beams forming the sides of the basket frame can be integrated into integral parts of the elevator car walls. Thus, the vertical beams form part of the walls of the elevator car, i.e. they may form part of the exterior surfaces of the elevator car walls, part of the interior surfaces of the elevator car walls, part of both interior and exterior surfaces or vertical beams acting as load-bearing structures.

Preferably, the vertical beams serving as the carrier structure of the car are shaped such that their outer surface is substantially flush with the outer surfaces of the other wall elements of the elevator car. Similarly, the inside surfaces of the vertical beams may be substantially flush with the interior surfaces of the other wall elements. If the rigidity of the structure requires it, it is of course possible that the wall elements forming the vertical beams are somewhat thicker than the other wall elements, whereby they preferably extend somewhat outside the outer surfaces of the other wall elements.

• · · • · »···

In one preferred embodiment of the invention, the vertical beams do not extend fully to the inner surfaces of the other wall elements. In this case, separate surface panels can be attached to the vertical beams to provide a flat or desired shape of the interior walls of the basket.

In one embodiment of the invention, the vertical bar is made of a rigid profile provided with a space • 1 ·: ... · for a push button unit. Similarly, in such a profile, the 107250 4 may have space for the lighting module. Generally, a sufficiently rigid steel sheet can be used, the longitudinal edges of which are bent from the main plane of the sheet into curved or pivotable rigid sheets. The stiffeners may be bent, for example, into an open or closed square profile.

In one embodiment of the invention, the vertical beam is profiled rigid so that it also forms an outwardly extending vertical groove or trough which can be used as a guide space in which the guide supporting the elevator car in the elevator shaft partially passes as the car moves in the shaft. This minimizes the strain gauge between the guides in the elevator shaft.

In one embodiment of the invention, the separate lower bracket of the frame frame is also replaced by a rigid floor. In this case, the rigid wall elements forming the vertical beams are joined at their lower ends by a rigidly supporting and rigid floor so that no separate lower support is required. Preferably, the floor consists of a rigid frame or frame beams which are covered with a suitable cover plate. In a preferred embodiment of the invention, the topsheet is bent at its edges downwardly to the edges of the body such that the topsheet has an edge of "**". These are the mounting brackets to which the lower wall members of the body are supported and secured.

In one embodiment of the invention, below the floor! • · • 1 ·· 30 includes brackets with sliding shoes and grippers attached to the rails. Similarly, ropes can! be supported on these supports or elsewhere below the floor.

35 In one embodiment of the invention, the upper support of the basket frame is also formed from the ceiling or part of the basket! watch. Depending on the suspension of the bodywork and the position of the ropes <107250 5 in the bodywork, the top support can be made a suitable roof element on a case-by-case basis.

The elevator car according to the invention has significant advantages over the prior art. According to the invention, the entire basket frame serving as a supporting structure can be made into parts of the basket and not as a separate frame surrounding the basket. This reduces the consumption of raw material and allows the construction of relatively inexpensive rul-10 flat-formed profiles. The bodywork is lighter and space is saved in the shaft so that larger elevator baskets can be used in the same shaft or smaller elevator shafts can be built. In addition, the number of parts needed in the elevator car is significantly reduced, which significantly accelerates the installation of the cars in the shaft.

In the following, the invention will be described in detail with reference to the accompanying drawings, in which Figure 1 shows an elevator car according to the invention and Figure 2 shows the car frame of Figure 1.

Figures 1 and 2 show a <: <25 elevator car according to the invention, in which the basket frame is integrated as an integral part of the elevator car. The basket frame consists of rigid straight vertical beams 1, which at their upper ends are rigidly connected to one another by a rigid upper support 2. At its lower end, the vertical beams «are rigidly connected to each other by a lower support 3, ie. in this application, a profile bent from an elongated steel plate having edge stiffeners 17 · ... at both edges and a middle plate 18 formed by a straight plate between the edge stiffeners. The top support 2 is also made of the same profile list.

1 c {(<«<« «· * · · • · 107250 6

Instead, the lower support 3, i.e. the rigid floor 6, consists of a rigid frame, i.e. a welded frame structure or separate rigid frame beams oh attached to one another and a top plate 5 on top 12. The edges of the top plate are turned down edges and the chassis flush with the underside flipped sideways and further upwards to form a trough mounting bracket 13 on each edge of the floor.

10

Below the floor frame 6 of the basket frame there are substantially legs 14 extending from the vertical beams 1, to which both the sliding shoes 15 and the grippers 16 are attached to the stall, whereupon the rope wheels 19 are supported.

When the elevator car is installed in the shaft, the rigid basket frame of Figure 2 is first mounted part-by-rope on the ropes to rest on the guides 20. Thus, when the carrier frame is a supporting structure in the shaft, the elevator car floor 6 is The vertical beams 1 form one of the wall elements of the elevator car, whereby the actual wall elements 4 of the elevator car are mounted on the floor mounting brackets 13. on both sides of the vertical beams 1 such that the outer surface 8 of the vertical beam is substantially flush with the outer surface 7 of the other wall elements 4.

In the embodiment shown, in the vertical beam, the edge stiffeners 17 of the profile are bent inwards such that the planar middle portion 18 of the profile forms the outer surface of the vertical beam. In this way, a space 11 is formed inside the profile between the stiffeners between the paths 17 and 35; for example, a push button unit and a luminaire module can be installed. Finally, the inner surface of the vertical beam 1 is covered by a surface panel 10 which aligns the vertical beam area with the inner surface of the other wall elements.

Similarly, in the roof of an elevator car, one of the roof elements is formed by the top bracket 2, and on both sides thereof, the other roof elements 5 are fixed on the wall elements to substantially the same horizontal plane as the top bracket 2.

10

In the elevator car, the vertical beams 1 with the surface panels 10 are substantially as thick as the wall elements 4. Thus, the side walls of the elevator car form structures of substantially uniform width throughout their height, thereby eliminating a minimum of shaft space. Correspondingly, when the floor 6 of the elevator forms the lower frame 3 of the basket frame, there is no need for space for different stiffeners under the basket. Thus, it is possible to carry out the installation of the rope wheels 19, as shown, so that the rope wheels 20 are on different sides of the line formed by the rails 20 on opposite sides of the elevator car. In this case, the wheel set is aligned with the center of mass of the elevator car, which is not possible with elevator cars with conventional basket doors, in which a part of the basket below the floor 25 is in front of a corresponding arrangement.

The invention has been described above by way of example with reference to the accompanying drawings, in which various embodiments of the invention are possible within the scope of the inventive inventive idea.
