FR2626864A1 - Lift car formed essentially of a standard panel and method of production - Google Patents

Abstract

The lift car is formed essentially of identical interchangeable, reversible standard panels, assembled together by simply positioning without nuts or screws, and the sizes of which determine the number of standard panels to be used. According to one embodiment of the invention, the panels 1, 2, 3, 4 are assembled together by interlocking using folds 5, 6 and 7; they are positioned and fixed to the floor 10 and to the ceiling 11 using ties 12.

Description

ESSENTIALLY ESTABLISHED ELEVATOR CAB
FROM A STANDARD PANEL AND EMBODIMENT
The present invention relates to an elevator car essentially consisting of identical and interchangeable standard panels, assembled together by simple installation, without nut or screw, and the dimensions of which determine the number of standard panels to be used.

Its advantages are manifold and can, without limitation, be listed as follows:
- possibility mainly from a standard panel, to produce finished products of various dimensions.

 - easy assembly and disassembly, by simple installation or removal, or ac e to the folds provided.

 - no need for a workspace outside the cabin, since all the manipulations are done inside the canine or from the roof of the elevator.

 - greater rigidity compared to known products.

 These characteristics are very specific to the product presented, which can therefore be described as innovative.

 Indeed, the models existing to date are not developed from a standard panel and their method of assembly, by screws, nuts, requires relatively long work, carried out outside the cabin.

 All of these elements make the product presented very competitive in terms of production costs.

 The present invention is therefore of certain interest.

It is shown, by way of nonlimiting example in the attached drawings:

According to an embodiment of the invention and according to FIGS. 1 to 8, the elevator is produced using 1 type of panel, a standard panel (1), of fixed dimensions and shapes, a panel rear end (2), a rear central panel (3), of variable dimensions and fixed shapes and a panel with chute (4) which is a type panel (1) as to its shape and dimensions. The standard panels (1) which are all identical and interchangeable, have on one side a fold t5) of dimension a and b + 1 mm and on the opposite side, a fold (6) of dimension a and b, studied so as to what it fits into the fold (5) during the assembly of two panels (1) between them, The last panel forming the rear end of the walls of the elevator, or panel (2), comprises on 1 1a of its dimensions a fold (7) of dimension b and, on the opposite side, a fold (6) identical to that of the preceding panel (1). The rear central panel (3) has, on two of its opposite sides , a fold (5). On a panel (4) of the type (1) a chute (8) allows the positioning of the elevator control members. The panel (4) is reversible and can be positioned on the left or on the right thanks to a cutout (9) provided for this purpose on the chute (8). During assembly, the various cutouts (5), (6), (7), fit into each other.

Figure (6) shows the method of fixing and positioning the panels to the floor (10) and the ceiling (11) using tie rods (12).

Figure (1) shows the principle of assembling the panels together.

Production
The realization of an elevator of given dimensions requires the installation of a number of corresponding standard panels (1), on which are adapted panels (2) and (3) made in the required dimensions and a panel (4) .

Claims (4)

 1) Elevator car, characterized in that it consists of a variable number of identical and interchangeable standard panels (1), a panel (4) with chute (8), and panels (2), ( 3) of determined shapes and of variable dimensions, joining together only by interlocking by folds.  2) elevator car according to claim (1) characterized in that the assembly by interlocking of panels (1), (2), (3) and (4) is done by means of folds (5), (6 ) and (7), the shapes and dimensions of which are provided for this purpose, and their positioning and attachment to the floor (10) and to the ceiling (11) by means of tie rods (12).  3) elevator car according to claim (1) or claim (2) characterized in that the standard panel (1) comprising on one of its sides a fold (5) of dimensions a and b + I mm and on the opposite side, a fold (6) of dimensions a and b, in that the panel (2) forming the rear end of the walls of the elevator has on one of its sides a plS (7) of- dimension b and on the opposite side a fold (6) identical to that of the panel (I), in that the rear central panel (3) has on two of its opposite sides a fold (5) and in that the panel (4), of type (I), comprises a chute (8) allowing the positioning of the control members  4) elevator car according to any one of the preceding claims, characterized in that the panels (1), (2), (3), (4) are reversible, the reversibility of the panel (4) comprising the chute ( 8) being made possible by means of a cutout (9) provided for this purpose on the chute (8).
