DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0071] FIG. 1 discloses a traction elevator 1 mounted to an elevator shaft 2 of a building B. The elevator 1 comprises an elevator car 3 for receiving load to be transported. The car 3 and a counterweight assembly 4 are suspended from a suspension rope 5 passing via a hoisting machinery 6. The hoisting machinery 6 comprises a traction sheave 7 driven by means of an electric motor M. Between the suspension rope 5 and the traction sheave 7 occurs friction which is utilized for transmitting lifting power to the elevator system. The hoisting machinery 6 may comprise one or more additional pulleys 8 for guiding and controlling the suspension rope 5. The hoisting machinery 6 may be located at an upper machine room 9, or alternatively the system may be a so called machine room less elevator. A compensation chain or rope 10 may be connected between the counterweight assembly 4 and a bottom of the elevator car 3. The elevator car 3 can be driven to desired landings L or floors under control of one or more control units CU. Below a first or lowermost landing there may be a pit 11 of an elevator shaft 2. There may be buffers 12 in the elevator shaft below the first landing L1.

[0072] Further, at the landings L there are entrances E provided with opening portions OP formed to wall structures W of the building B. The opening portions OP are provided with door frames 13. The door frames 13 are in accordance with the features and embodiments disclosed in this document.

[0073] FIG. 2 discloses that a door frame 13 comprises upright frame parts 14 and upper frame parts 15. The door frame 13 is a three-sided structure installable in an opening portion of an entrance of the elevator whereby the door frame has a gate-like configuration comprising two opposite upright frame parts 14 covering both side portions of the opening portion OP and one upper frame part 15 disposed between upper end portions of the upright frame parts 14 for covering an upper portion of the opening portion OP. The upright frame parts 14 comprise mounting frame elements 14a and separate surface element 14b attachable removably to the mounting frame elements 14a. Correspondingly, the upper frame part 15 comprises a mounting frame element 15a and a separate surface element 15b attachable removably to the mounting frame element 15a. FIG. 2 further discloses that the surface elements 14b, 15b may be decorative panels 16 or functional panels 17.

[0074] FIG. 3 discloses a face of a door frame 13 seen from an elevator lobby L. The door frame is mounted to an opening portion OP of a wall structure W and comprises upright frame parts 14 and an upper frame part 15 arranged between their upper end portions. Doors D of the elevator are also shown.

[0075] FIG. 4 discloses an opening portion OP of an entrance E. Surfaces S of the opening portion OP may comprise roughness and other esthetical faults as well as dimensional variances which all can be solved by means of the door frame disclosed in this document.

[0076] FIG. 5 discloses an assembled structure of a mounting frame 18 of a door frame 13. The structure can be assembled before installing it to a door opening. The assembly of the structure can be facilitated by using angular elements 19 at corners 20 between mounting frame elements 14a, 15a. Between lower end portion of the mounting frame elements 14a may be a transverse installation support 21 which is removed together with the angular elements 19 after the complete mounting frame 18 is fastened to the door opening by means of screws or other fastening elements. FIG. 6 is a detailed view of the corner 20 provided with the temporary angular element 19.

[0077] FIGS. 5 and 6 further show that the mounting frame elements 14a, 15a may comprise openings 22 or other forms for providing shape locking surfaces for surface panel elements mountable on the mounting frame element 14a, 15a.

[0078] FIG. 7 discloses mounting step of a surface element 14b to a mounting frame element 14a of a mounting frame 18 installed to a door opening. Detailed FIGS. 8 and 9 disclose that the surface element 14b may comprise hooks 23 for forming shape locking with openings 22. When the surface panel 14b is mounted on the mounting frame element 14a a free space 24 may be formed between them. Inside the free space may be electrical cables 25, coupling components 28, and first installations 26. Further, the surface panel 14b may comprise second installations 27. The installations 26, 27 may be electrical devices, for example.

[0079] Further, it may be possible to arrange protrusions on the mounting frame elements and openings to surface panel elements.

[0080] FIG. 7 further discloses that the surface element 14b may comprise two or more components b1, b2. In Figure the components are one after each other but they may also be side to side. The same structural possibility is suitable also for other surface elements of the door frame.

[0081] FIGS. 10 and 11 disclose some possible features and devices which different decorative surface element 16 and functional surface elements 17 can offer.

[0082] Implementation of the disclosed solution is not limited to the exemplary elevator disclosed in FIG. 1. Further, the disclosed solution may implement also other mounting principles between the mounting frame elements and surface elements. There may screw mountings, quick coupling elements and pop-in fasteners, for example.

[0083] The drawings and the related description are only intended to illustrate the idea of the invention. In its details, the invention may vary within the scope of the claims.
