DETAILED DESCRIPTION

(8) FIG. 1 shows an elevator installation 100 as is known from the prior art, for example with 2:1 suspension illustrated. An elevator car 2 is arranged in a displaceable manner in an elevator shaft 1 and is connected to a displaceable counterweight 4 via a supporting and driving means 3. The supporting and driving means 3 is driven, during operation, by means of a driving pulley 5 of a drive unit 6, these being arranged in a machinery compartment 12 in the uppermost region of the elevator shaft 1. The elevator car 2 and the counterweight 4 are guided by means of guide rails 7a and 7b and 7c extending over the height of the shaft.

(9) Over a conveying height h, the elevator car 2 can serve an uppermost floor door 8, further floor doors 9 and 10 and a lowermost floor door 11. The elevator shaft 1 is formed from shaft side walls 15a and 15b, a shaft ceiling 13 and a shaft floor 14, on which are arranged a shaft-floor buffer 19a for the counterweight 4 and two shaft-floor buffers 19b and 19c for the elevator car 2.

(10) The supporting and driving means 3 is fastened at a fixed-location fastening point or supporting-means-fixing point 16a on the shaft ceiling 13 and is guided, parallel to the shaft side wall 15a, to a supporting roller 17 for the counterweight 4. From here, in turn, the supporting and driving means 3 is guided over the driving pulley 5 to a first deflecting or supporting roller 18a and, passing beneath the elevator car 2, to a second deflecting or supporting roller 18b and to a second fixed-location fastening point for a supporting-means-fixing point 16b on the shaft ceiling 13.

(11) FIG. 1 also shows, symbolically, a closed drainage system 200 for extinguishing water which uses closed pipelines and pipe connections to channel away extinguishing water into the shaft floor 14 from each individual floor and/or each individual shaft door 8-11.

(12) FIG. 2 shows, schematically, an example of an elevator car 2a, which is a constituent part of an example of an elevator installation 100a. The elevator car 2a is supported by a supporting and driving means 3a which is guided by deflecting or supporting rollers 18c and 18d, of which only the deflecting or supporting roller 18c is visible in the perspective illustration shown. The cuboidal basic structure of the elevator car 2a has four fastening struts 21a-21d in extension of four more or less vertical corner edges 20a-20d (of which, on account of the perspective view, only the corner edges 20a-20c are visible).

(13) A rigid drainage panel 22 is fastened on these four fastening struts 21a-21d, flush in relation to an upper edge 27 of the elevator car 2a, and forms a first drainage surface 23a, having an approximate angle of inclination W.sub.1 of 30 degrees to a horizontal H, and a second drainage surface 23b, having an angle of inclination W.sub.2 of more or less 60 degrees to the horizontal H. A more or less vertical connecting panel 24a or 24b is connected to the drainage surfaces 23a and 23b and to the fastening struts 21a, 21d and 21b, 21c, respectively.

(14) Extinguishing water which comes into contact with the drainage surfaces 23a and 23b is thus collected and will flow down a side surface 25 of the elevator car 2a and be deflected by an optional lip 26. The drainage surfaces 23a and 23b, the connecting panels 24a and 24b, the side surface 25 and the lip 26 thus form a first elevator-car drainage system 200a according to the invention.

(15) FIG. 3 illustrates, schematically a variant of an elevator car 2b and/or of an elevator installation 100b. The elevator car 2b, supported by a supporting and driving means 3b in a visible deflecting or supporting roller 18e and in a concealed deflecting or supporting roller 18f, has a side surface 25a between a corner edge 20e and a further corner edge 20f, a further side surface 25b between the corner edge 20f and a further corner edge 20g, and a further side surface 25c between the corner edge 20e and a corner edge 20h, which is not visible in the perspective view illustrated. The side surfaces 25a, 25b and 25c form an upper edge 27a of the elevator car 2b. Fastening struts 21e, 21h are arranged on this upper edge 27a, in extension of the corner edges 20e-20h, and a drainage panel 22a and more or less vertical connecting panels 24c and 24d are fastened on said fastening struts.

(16) In a manner analogous to the drainage panel 22 from FIG. 2, the drainage panel 22a is formed from two drainage surfaces 23c and 23d, of which the drainage surface 23c is inclined by an angle of inclination W.sub.3 of more or less 30 degrees to a first horizontal H.sub.1 and the drainage surface 23d is inclined by an angle of inclination W.sub.4 of approximately 60 degrees to said first horizontal H.sub.1. The drainage surfaces 23c and 23d, in turn, each form two sub-surfaces 28a, 28b and 28c, 28d, which are inclined in a mirror-inverted manner, and in the direction of the upper edge 27a, by a respective angle of inclination W.sub.5 and W.sub.6 of more or less 30 degrees to a second horizontal H.sub.2.

(17) Two gutters 29a and 29b, each with a flow-off means or discharge means 30a and 30b, respectively, are arranged on the side surface 25a, flush with the sub-surfaces 28c and 28d. This means that the extinguishing water is collected on the roof of the elevator car 2b, channeled away to the side surfaces 25a-25c, collected in the gutters 29a and 29b and discharged via the flow-off means or discharge means 30a and 30b at the corner edges 20e and 20f of the elevator car 2b.

(18) For further protection of the supporting and driving means 3b, a vertical drainage panel or splash guard 31a, 31b is arranged, in the form of an angled profile, on each of the side surfaces 25b and 25c, respectively.

(19) The drainage panel 22a illustrated, the more or less vertical connecting panels 24c and 24d, the gutters 29a and 29b and the vertical drainage panels or splashguard 31a and 31b form a second variant according to the invention of a drainage system 200b on the elevator car 2b and/or in the elevator installation 100b.

(20) As an optional variant, it is possible for the flow-off means or discharge means 30a and 30b to be arranged by means of two connecting tubes on the lower edge of the elevator car 2b and, as a further option, for the extinguishing water which collects on the vertical drainage panels or splashguard 31a and 31b to be fed to these discharge means 30a and 30b or flow-off means arranged on the lower edge.

(21) FIG. 4 shows, schematically, an example of an elevator shaft 1a, which is a constituent part of an example of an elevator installation 100c. Of the side walls of the elevator shaft 1a, shaft side walls 15c and 15d, which are at more or less right angles to one another, are illustrated in the figure. The floors are indicated by an intermediate floor or screed floor 40a, and each have a floor door or shaft door 9a and 10a. A respective door lintel 39a, 39b is located on the upper side of the shaft doors 9a and 10a. Located on the underside of the shaft door 9a is a shaft-door sill 32a, which comprises channel crosspieces and has through-openings or apertures or bores 33a, preferably both in the channel crosspieces and in the grooves located therebetween. The bores 33a here are in a pattern which is narrower in the center of the shaft-door sill 32a and widens in the direction of the sides.

(22) Beneath the shaft-door sill 32a, the shaft side wall 15c has arranged on it an intercepting panel 34a, which forms a more or less vertical sub-surface 35athat is to say one which is parallel to a vertical V.sub.1and a sub-surface 36a which is inclined at an angle of inclination W.sub.7 to the vertical V.sub.1. At least the inclined sub-surface 36a, or also, in addition, the more or less vertical sub-surface 35a, forms, in a mirror-inverted manner, from approximately the center of the intercepting panel 34a, a respective angle of inclination W.sub.8 or W.sub.9 to a horizontal H.sub.3.

(23) Accordingly, as indicated by arrows, extinguishing water 46a flows through the shaft-door sill 32a, is collected by the intercepting panel 34a and fed laterally, in each case through outflow openings 45a and 45b, into receiving openings 38a and 38b of a respective intercepting profile 37a, 37b. In order to show clearly an open drainage system 200c for extinguishing water belonging to the shaft, further intercepting profiles 37c and 37d, each with respective receiving openings 38c and 38d, are arranged at a distance A.sub.1 and serve for receiving the extinguishing water which would come out of a shaft door above the shaft door 9a. The distance A.sub.1, on the one hand, is decisive for reliable transfer of extinguishing water from the higher intercepting profiles 37c and 37d into the lower intercepting profiles 37a and 37b and, on the other hand, is decisive for extinguishing water being reliably received from the outflow openings 45a and 45b, but also for extinguishing water which is intercepted on the roof of the elevator car 2a and 2b from FIGS. 2 and 3 being reliably received.

(24) FIG. 5 illustrates, schematically, a variant of an elevator shaft 1b and/or of an elevator installation 100d. In a manner analogous to FIG. 4, a shaft door 9b with a door lintel 39c and a shaft-door sill 32b, with through-openings or apertures or bores 33b, and a further shaft door 10b with a door lintel 39d are illustrated in a shaft side wall 15e. An intermediate floor 40b passes through both the shaft side wall 15e and a further shaft side wall 15f, which is ranged more or less at right angles.

(25) Beneath the shaft-door sill 32b, an intercepting panel 34b is arranged on the shaft side wall 15e. This intercepting panel 34b is open at the top and has a more or less vertical sub-surface 35b and an inclined sub-surface 36b, which adjoins the surface 35b and is at an angle of inclination W.sub.10 to a vertical V.sub.2. The intercepting panel 34b also has side surfaces 41a and 41b. Beneath the intercepting panel 34b, a flow-off panel 42 is arranged likewise on the shaft side wall 15e, and this flow-off panel improves the flow-off behavior of extinguishing water 46b which has penetrated through the shaft-door sill 32b and is intercepted by the intercepting panel 34b and passed on, on account of the laterally bounding side surfaces 41a and 41b, exclusively centrally through a gap-like outflow opening 45c between the inclined sub-surface 36b and the shaft side wall 15e.

(26) It is also possible for the flow-off panel 42 to be larger than illustrated and/or to be connected to the inclined sub-surface 36b and a drainage panel 43 arranged beneath the flow-off panel 42. Said drainage panel 43 is at an angle of inclination W.sub.11 to the vertical V.sub.2 and, in addition, is inclined downward in a mirror-inverted manner, from approximately its center toward the sides in each case, by an angle of inclination W.sub.12, W.sub.13 to a horizontal H.sub.4, and therefore the extinguishing water 46b flowing off from the flow-off panel 42 is directed thereby, via respective outflow openings 45d and 45e, into a receiving opening 38e of an intercepting profile 37e and a receiving opening 38f of an intercepting profile 37f.

(27) Once more, in order to show clearly an open drainage system 200d for extinguishing water belonging to the shaft, it is illustrated that further intercepting profiles 37g and 37h, each with respective receiving openings 38g and 38h, are arranged at a distance A.sub.2 above the intercepting profiles 37e and 37f in the corners of the elevator shaft 1b.

(28) Furthermore, the elevator shaft 1b has, in the shaft side wall 15f, a vertically running slot 44, in which the drainage panel 31a or 31b from FIG. 3, said drainage panel being arranged on the elevator car 2b, can run along, as a splashguard, in a recessed manner.

(29) 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.
