CAR FLOOR FOR AN ELEVATOR CAR AND METHOD FOR INSTALLING AN ELEVATOR CAR

Abstract

A car floor for an elevator car includes a planar base part and installation feet arranged thereon. The installation feet support the car floor on the shaft floor of an elevator shaft during the elevator car installation phase. In order to orient the base part in a horizontal position, each of the installation feet is in the form of a height-adjustable installation foot. The height-adjustable installation foot has a threaded rod as part of a threaded spindle for height adjustment.

[0023] FIG. 3 shows the car floor with car side walls mounted thereon,

[0024] FIG. 4 shows a perspective representation of an elevator car floor in accordance with the invention, and

[0025] FIG. 5 shows a perspective partial view of a corner region of a car floor in accordance with an alternative embodiment.

DETAILED DESCRIPTION

[0026] FIG. 1 shows a lower region of an elevator shaft 6 for an elevator system denoted as a whole by 1. In the present case, the elevator system 1 has an elevator shaft 6 having a small pit depth. A car floor denoted by 3 is located on the shaft floor 7 of the elevator shaft 6. The car floor consists of a base part 4, which defines a standing area for passengers, and of installation feet 5, 5 via which the car floor 3 is supported on the shaft floor 7.

[0027] Concrete is frequently used to produce the elevator shaft. It is difficult to produce the shaft floor 7 so as to have a planar and horizontal surface. Therefore, the car floor may have a slight tilt after being set down for the first time. This tilt can be eliminated by means of height-adjustable installation feet 5, 5. For this purpose, as shown by way of example in FIG. 2, the height-adjustable installation foot 5 is adjusted in height until the base part 4 is brought into the desired horizontal position. After the base part 4 has been oriented, installation of the elevator car 2 can be continued as shown in FIG. 3. The car side walls 8 can now be mounted on the car floor 3 leveled in this manner. After the car side walls 8 have been mounted, the car roof 9 indicated by dashed lines can finally be fitted on the car side walls 8.

[0028] FIG. 4 is a perspective view of a rectangular car floor 3 having four height-adjustable installation feet 5 arranged in corner regions. The respective installation feet 5 are arranged on the outside of the base part 4 in the corner regions thereof via spacer elements 14. In the present case, the spacer elements 14 are designed as angular pieces which are fastened to the vertical side wall portions 17 of the base part 4. In the embodiment in accordance with FIG. 4, the height-adjustable installation feet 5 are arranged outside the vertical projection of the base part 4. FIG. 5 shows a variant in which the height-adjustable installation feet 5 are arranged within the vertical projection of the base part 4.

[0029] The height-adjustable installation feet 5 are designed and can be actuated manually in such a way that the height adjustment can take place from the base part 4. The tilt (indicated by the angle of inclination a of the car floor relative to the horizontal in FIG. 1) can be eliminated in this way. In the example shown in FIG. 2, the installer 19 actuates the left-hand height-adjustable installation foot denoted by 5. For the height adjustment, the relevant installation foot 5, 5 can be moved upward and downward in the vertical direction (indicated by an arrow) by mechanical means 10, for example by means of a screw mechanism.

[0030] As can be seen from the two embodiments in accordance with FIGS. 4 and 5, the installation foot 5 can be adjusted in height by means of a threaded spindle. The height-adjustable installation foot 5 comprises a threaded rod 11, which is accommodated in an internal thread which is associated with the base part 4 and corresponds to the threaded rod. On account of the threaded rod 11 extending in the vertical direction, the car floor 3 can be raised or lowered locally at the relevant car foot and the desired height can thus be set precisely.

[0031] In the embodiment in accordance with FIG. 4, the spacer elements 14 contain the internal threads in which threaded rods 11 of the installation feet 5 are received. As shown in FIG. 4, stamp-like support elements 12 can be arranged on lower ends of the threaded rods 11 facing the shaft floor in order to increase the contact surface area with respect to the shaft floor 7. To actuate the threaded spindle, the upper threaded rod end of one of the threaded rods 11 is, for example, gripped by means of a tool (not shown here) and rotated as desired either in the clockwise direction or in the counterclockwise direction in order to adjust the height.

[0032] In the embodiment in accordance with FIG. 5, the base part 4 has internal threads integrated therein or arranged on the inside, in which the respective threaded rods 11 are received. In the present embodiment, a screw nut 13, which is secured to the base plate 16 and with a metal sleeve adjoining it, has the internal thread. By way of example, a screw head 18 for an Allen key is provided on the upper end of the threaded rod 11. Of course, other engagement or actuating means for the height adjustment are also conceivable. For example, instead of the screw head shown by way of example, rotary handles, thumb screws, or tommy screws are possible as actuating means.

[0033] It can be seen from FIG. 5 that the base part 4 is a planar component in a composite structure or sandwich construction. The base part 4 substantially consists of the base plate 16, a cover plate 15, and an intermediate composite structure core (not shown specifically).

[0034] To check the horizontal position, spirit levels 20, for example a circular spirit level or two tubular spirit levels arranged crosswise with respect to one another, can be fastened to the base part 4 (FIG. 2).

[0035] In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
