Elevator car

Abstract

Example embodiments relate to an elevator car, including a car spoiler at its top and/or bottom thereof, a car sling with a horizontal frame part on which at least one elevator cabin is supported, and at least one vertically extending spoiler element is located aside of the horizontal frame part. The spoiler element may have upper and lower flange portions, at least one of the upper and lower flanges being connected with elevator car parts located above and/or below of the frame part, and a vertically extending middle portion. The spoiler element may be arranged a distance from the frame part. An elevator car having this arrangement may reduce noise and provide better efficiency.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is hereinafter described schematically with respect to the enclosed drawings.

(2) FIG. 1 shows a perspective view of an elevator car having two cabins placed one above each other,

(3) FIG. 2 shows a perspective view of the detail II from FIG. 1,

(4) FIG. 3 shows a side view of the detail II of FIG. 1, and

(5) FIG. 4 shows an enlarged cross-sectional view of the detail II of FIG. 1.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

(6) FIG. 1 shows an elevator car 10 having an upper cabin 12 and a lower cabin 14 which are suspended on an upper sling platform 16 and a lower sling platform 18 of a car sling 20. Both cabins have door openings 13 in which usually telescopic slide doors are provided. On top of the upper cabin 12, an upper car spoiler 22 is located which has on the door side of the cabins 12, 14 a spoiler plate 24 having a hatch 26 to obtain access to the roof of the upper cabin 12 for maintenance purposes.

(7) The elevator car 10 also comprises a lower car spoiler 28 which has a lower spoiler plate 30 below the lower cabin 14 comprising a hatch 15 for getting maintenance access for the space between the bottom car spoiler 28 and the floor of the lower cabin 14. On the sides of the elevator cabins 12, 14, spoiler plates 32 are arranged to provide a cladding of the elevator car 10 also on its lateral sides so as to provide a reduced air resistance and reduced turbulences between the car sides and a surrounding elevator shaft wall. The upper and lower sling platform 16, 18 are stabilized at the car sling 20 via support arms 21 extending to both sides of vertical part 23 of the car sling 20. The car sling 20 also comprises guide rollers and gripping elements 34 on the top and bottom of the vertical part 23 of the car sling 20 via which the elevator car 10 is guided along guide rails provided in an elevator shaft. The car comprises in the top also a fixing for the hoisting ropes of the elevator (not shown) via which the elevator car is suspended in an elevator shaft, preferably running via a traction sheave of an elevator drive machine unit. The upper and lower sling platform 16, 18 are cladded via spoiler elements 36 located side by side which can better be seen in a perspective view of the detail II from FIG. 1 shown in FIG. 2, in the side view of FIG. 3 and in the sectional view of said detail according to FIG. 4.

(8) The spoiler elements 36 have an upper flange portion 40, a lower flange portion 42 and a middle portion 44 which all extend vertically. It is clear that the spoiler element is intended to extend essentially vertically to cover the region of the horizontal frame part or sling platform of the car sling but it may also be tilted with respect to a vertical in a certain range, for example +/20 degrees, particularly if it has curved portions.

(9) The upper and lower flange parts 40, 42 and the middle portion 44 are connected with each other via connecting portions 46 which are tilted with respect to the vertical upper and lower flange portions 40, 42 and the middle portion 44 within an area of preferably 10 to 45 degrees. The upper flange portion 40 of the spoiler element 36 is fixed to the cabin floor 50 of the upper cabin 12 which is supported via a spring and/or dampening means 52 on the sling platform 16. The lower flange portion 42 of the spoiler element 36 butts against an upper intermediate spoiler plate 54 of the lower cabin 14 which surrounds the top of the lower cabin to enable maintenance persons to provide maintenance work there on elevator components, as for example the door operator. On the car door side the top of the lower cabin is cladded by an intermediate front spoiler plate 27 comprising a hatch 15 to enable access to the roof of the lower cabin 14. Via the spoiler elements 36, the area around the sling platform 16 is cladded without coming into contact with the sling platform 16 itself so that noise which is transmitted to the car sling via the guide rollers and the hoisting ropes is kept away from the cabins and the spoiler parts of the elevator car.

(10) The fact that the lower flange portion 42 only abuts against the upper intermediate spoiler plate 54 of the lower cabin 14 has the advantage that mutual movements between the upper cabin 12 and the lower cabin 14 are possible which are supported with their own spring and dampening means 52 on the corresponding sling platforms 16, 18. It is needless to say that the sling platform 16, 18 does not need to be embodied as a sling platform but it can be realized as a horizontal beam or horizontal rectangular supporting structure.

(11) Also the lower sling platform 18 is cladded by the spoiler elements 36 described above, whereby their upper flange is fixed to the floor of the lower cabin 14 and the lower flange abuts against the lower car spoiler 28.

(12) It shall further be clear that the invention is not restricted to the above-mentioned embodiments but may be varied within the scope of the appended patent claims.
