- the Motor powered by an auxiliary power source in the event of a power failure.
- the upper add-on element is fastened via a Centering device on the top of the cabin put on and only with its own weight in the set position kept reliable.
- the elimination of any mounting fittings facilitates its rapid removal by immediate lifting in the Emergency.
- the centering device consists of an am on the element side Element edge, for example riveted, centering with Profile edge and cabin side from a centering frame with same second profile edge matching the first profile edge.
- both profile edges form a secure one Positive connection between the attached element and the Elevator car, with an elastic liner between the Profile edges have a noise and vibration dampening effect.
- the attachable upper attachment element also has a guide side a channel-shaped indentation, which is spaced on all sides surround the guide roller carrier.
- the course of the flow is the inner surface of the indentations Vertical slightly slanted towards the cabin center and the Transitions to the side surfaces gently rounded.
- At least one detachable separating seam enables the upper one to be installed Extension element in at least two halves. Is only a dividing seam provided, it is preferably at right angles to Management level provided.
- the lower attachment element is a frame-shaped hollow body trained and is by means of a profiled mounting edge attached to the bottom of the cabin.
- Channels molded on both sides enclose the lower ones Guide roller carrier to avoid air turbulence at high Driving speed. They serve the same purpose subsequent, somewhat cantilevered paneling for the Guide rails.
- the underside of the lower attachment element is curved Inside of the frame and two hinged lids to open. These hinged lids provide access to the electrical and mechanical fittings underneath the cabin guaranteed. Simple, manually operated closures hold the Lid in the closed position.
- the attachments above and below are lightweight, preferably made of fiber-reinforced plastic and have if necessary reinforced with ribs on the inside, a high one Dimensional stability so that even at high speeds no vibrations of the element walls occur.
- FIG. 1 shows an elevator car 1 with the one according to the invention Device shown, which is essentially one on the Upper add-on element 3 placed on top of elevator car 1 and a lower one attached to the underside of the elevator car 1 Attachment 4 has.
- the elevator car 1 runs by means of the lower one and upper guide rollers 5 and 7 on guides 2.
- Die Guide rollers 5 and 7 are on guide roller carriers 6 and 8 vertically spaced from the prismatic cabin body and protrude vertically beyond the add-on elements 3 and 4.
- Existing cabin ropes, lower ropes and hanging cables are closed In favor of a clear representation of the add-on elements 3 and 4 omitted in this Fig.1.
- Cantilevered parts and Indentations of the add-on elements 3 and 4 partially enclose the Guide roller carriers 6 and 8 and the guide rails 2.
- FIG. 2 shows the upper add-on element 3 from the guide side seen with a channel-shaped indentation 9.
- the thereby created free space around the guide roller carrier 6 largely enables one at high driving speeds free air flow in this zone.
- the three inner ones Flanks of the side recess 9 shaped so that the Indentation 9 extends somewhat vertically upwards.
- An opening 31 on the top of the upper attachment 3 is used for implementation of suspension cables for the elevator car 1.
- a detachable separating seam 30 provided which, for example, at right angles to Management level runs.
- FIG. 3 shows in cross section the formation of the lower edge zone the upper attachment 3 and the details of its connection with the elevator car 1.
- the lower edge zone is at the Element wall 10 on the circumference of the upper add-on element 3 stiffening, multi-angled centering plate 11 attached, which is horizontal in a gable roof-shaped profile edge 12 ends.
- the top of the elevator car 1 is off a frame-shaped centering attachment 14 Mistake.
- the bending profile of the centering attachment 14 has one profile roof-shaped profile edge 15, which fits exactly the same Has shape like the profile edge 12 of the centering plate 11.
- With 13 is an elastic intermediate layer called, for example is glued to the profile edge 15 of the centering frame 14.
- the elastic intermediate layer 13 serves to dampen noise and Vibrations. From Figure 3 it can be seen that the on Centering frame 14 attached top attachment 3 form-fitting is held against lateral displacement and by No additional weight even in the vertical direction Attachment required. By simply lifting the add-on element 3 the top of the elevator car becomes accessible.
- Fig. 4 shows the plastic ellipsoid-like shape of the upper attachment element 3.
- rounded transitions from side to side and to the Indentations 9 can be seen. These gently rounded transitions only result in one between the different surface zones airflow flowing around when driving fast.
