System of component parts of an elevator system at the floors of the elevator shaft and mounting method thereof

Description

Field of the invention

[0001] The present invention relates to a system of component parts of an elevator system at the floors of the runway, and relative mounting method, adapted to allow the mounting of doors at the floors, and interchangeable modular infill of the runway of said elevator system.

State of the art

[0002] Elevator systems are installed inside an elevator runway that is generally constructed at the same time as the structural elements of buildings.

[0003] Said elevator runway is therefore made of reinforced concrete to define a parallelepiped that runs for at least the entire height of the building and which has an opening for each landing served by the elevator system.

[0004] Therefore, during construction of a building the structure or carcass is first produced, and subsequently the electrical, plumbing and heating systems, and the elevator system with relative landing doors, are installed. Only after this is it possible to carry out the finishes.

[0005] For safety reasons, it is preferable not to have different teams of workers working simultaneously at the building site.

[0006] This means that when those in charge of installing the elevator mount the doors at the landing, the floors, marble and/or wood defining the jambs of the openings of the elevator runway have not yet been installed.

[0007] However, it is not possible to reverse the order of installation as centering and squaring of the doors at the various floors must necessarily be ensured in the same position.

[0008] Moreover, masonry works are required after said installation works, which interfere with the quality of the final finish.

[0009] Therefore, installation of said finishing works results in a considerable loss of time and money.

[0010] In practice, the doors of the various floors must be equidistant and perfectly aligned with one another, so that the motors of the car can, by means of suitable couplings, open the doors correctly on each landing.

[0011] According to another aspect related to safety, during the works to build the carcass, the openings of the elevator runway must be blocked off in order to prevent people from accidentally falling into the elevator runway.

[0012] For this purpose, carpenters provide a barrier, generally made of wood, nailed to the walls defining the stairwell, until it is time for the team of workers to mount the doors at the floors.

[0013] Consequently, these workers must remove said barrier before starting to mount the doors at the landing, losing further time.

[0014] Therefore, a principal problem is that of reducing to a minimum any adjustments to the finishes after mounting of the doors at the floors, and another no less important problem concerning safety is that of ensuring that the openings of the elevator runway are blocked off on each landing.

[0015] EP 1 679 281 A1 discloses a system according to the preamble of apparatus claim 1.

Summary of the invention

[0016] The object of the present invention is to provide a system of component parts of an elevator system at the floors of the runway, and relative mounting method, adapted to solve said mounting and safety problems, and to allow mounting of doors at the floors, and modular infill of the runway of the elevator system.

[0017] A particular object of the present invention is a system of component parts of an elevator system at the floors of the runway, and relative mounting method, as better described in the claims, which form an integral part of the present description.

Detailed description of a preferred embodiment of the invention

[0020] The system forming the subject of the present invention provides for the mounting of an upper crosspiece 1 and a lower jig 2.

[0021] Said crosspiece and said jig define the exact position of the suspensions and of the thresholds of the doors of all the floors.

[0022] Mounting these in an elevator runway VA for each of the openings at the floors, before laying the flooring of a respective landing PT, ensures perfect centering of the various openings with respect to elevator travel.

[0023] Advantageously, preliminary positioning of a jig 2 and of an upper crosspiece 1 for each opening of the elevator runway allows constructional inaccuracies of the structures to be corrected, as workers called to lay flooring and apply plaster are obliged to take said jigs and crosspieces as reference for finishing each landing. Moreover, it is no longer necessary to carry out any structural preparation for positioning of the doors at each opening of the elevator runway, as positioning of the upper crosspiece 1 and of the jig 2 allows filling panels, defining the edge margins of the opening of the doors, to be installed.

[0024] Further, in conformity with the present invention, said upper crosspiece 1 is of a length equivalent to the width of the side of the elevator runway in which the opening is produced and is anchored to the runway at the ends, abutting against the side walls, to define a fixed-end beam.

[0025] This anchoring ensures that the position of the crosspiece can be adjusted to ensure it is plumb in relation to the respective jig 2 and consequently to all the other jigs of all the other openings of the runway at other floors.

[0026] Moreover, the lower jig 2 is also of the same length as the width of the side of the elevator runway in which the opening is produced, minus the dimensions of the finishes 37 and a further adjustment margin 38 (Fig. 3).

[0027] According to the invention, said lower jig has an S-shaped section in which an upper plate 2' and a lower plate 2" are parallel and staggered and joined by a transverse plate 2'" to the first two (Fig. 2).

[0028] Said jig 2 is mounted so that said upper plate 2' defines the level of the floor PV for the subsequent flooring step.

[0029] Said lower plate 2'', being staggered with respect to the upper plate 2', projects into the elevator runway for application of the threshold for sliding of the doors at the landing, which slide inside the elevator runway.

[0030] Preferably, said upper crosspiece 1 is produced by means of a box element, for example with a C-section with internal (or also external) folded edges, although other shapes can be used.

[0031] To anchor the upper crosspiece 1 against the lateral walls it is advantageous to use at least one pair of L-shaped elements 6, positioned symmetrically to each other with the supporting part arranged so as to exit from the shape of the upper crosspiece 1, for simple anchoring and coupling of the crosspiece to the lateral walls of the elevator runway.

[0032] Until the doors are mounted, one or more fall prevention rails 3 (preferably two) can be positioned between said upper crosspiece 1 and said lower plate 2" of said lower jig 2 to define a fall prevention barrier (Fig. 4).

[0033] For this purpose, said lower plate 2" and said upper crosspiece 1 comprise a suitable number of holes through which to anchor, for example with screws, or by interlocking, said fall prevention rails 3.

[0034] Advantageously, connection of said fall prevention rails 3 to said jig and to said crosspiece is such as to maintain the rails inside the elevator runway, avoiding any interference with the application of plaster, marble, wood or tiles.

[0035] Fig. 1 shows a section of an elevator runway VA at a landing PT. It can be clearly seen that the floor PV has been laid so as to pass under the upper plate 2' of the jig 2.

[0036] According to further variants of the invention, the floor can be taken perfectly to the level of said first plate 2' or can be at a slightly higher level to said plate. In fact, according to a preferred variant of the finding, said upper plate 2' is provided with an anti-slip covering (not shown).

[0037] According to another aspect of the invention, the plastering of the ceiling and of the walls can be applied with continuity up to the inner edge of the openings of the elevator runway VA, taking as reference the transverse plate 2'" of the jig and the edge of the upper crosspiece 1 outside the runway.

[0038] The jig 2 is associated with the floor of a landing PT, for example by means of two or more first square support elements 4. With reference to Fig. 4, in addition to or alternatively to said first square elements 4, second square elements can be provided, adapted to be associated with the lateral walls to support said jig 2 in proximity of the respective ends. Said square support elements comprise slots extending sufficiently to allow adjustable mounting of said lower jig 2 with respect to the runway VA, both vertically and horizontally.

[0039] Fig. 4 shows installation of said rails 3 associated with said crosspiece and with said jig. Said rails 3, in a preferred variant comprise one or more hooked elements 31, for insertion of planks or other suitable horizontal fall prevention elements 32 contributing towards blocking off access to the elevator runway.

[0040] Said rails 3 can comprise different anchoring means of horizontal fall prevention elements.

[0041] As can be seen from the figures, said elevator runway VA is preferably completely open, in the sense that at each landing its opening is defined at the perimeter by the floor, by the ceiling and by the lateral walls of the runway itself. In other words, instead of being formed of four sides, the elevator runway can be formed of only three sides, without counting the surface of the soffit depth which at each landing faces the elevator runway.

[0042] Fig. 5 shows an exploded view of the component parts for installation of the system at a landing, in a situation in which the opening of the elevator runway is complete. Horizontal 10 and vertical 11, 12 infill panels are also shown.

[0043] It can be noted that the upper crosspiece 1 and the lower jig 2 are advantageously of a length such as to almost entirely cover the width of the elevator runway.

[0044] In Fig. 5 it is assumed that the doors slide telescopically only on one side (left in the figure) but it is evident that in other installations the doors can open symmetrically, with one door opening to the left and one door opening to the right. The infill panels (10, 11, 12), installed subsequently, are composed of sheets comprising bends at the edges and structural support elements, inserted in the edge bends, in the inner part of the sheets facing the elevator runway. The edge bends are preferably only present on two opposite sides of the panel: for example, in the vertical panels 11 and 12 bends 20, 21 are present on the vertical sides, while in the horizontal panel bends 22, 23 are present on the horizontal sides. In the present context vertical and horizontal refer to the direction when mounted. More in particular, an upper support bar 30 is inserted horizontally between the bends 20, 21 of the vertical sheet 11, and anchored there in a slightly higher position to that corresponding to the crosspiece 1, with rivets. At least one square 31 in the shape of an S facing the inside of the panel is anchored to the upper bar 30. When mounting the panel, the square is used to hang the panel to the upper crosspiece.

[0045] A lower bar 32 is inserted horizontally between the bends 20, 21 of the vertical sheet 11 on the bottom thereof. After having hung the panel to the crosspiece, the upper bar is anchored to the crosspiece 1, while the lower bar is anchored to the jig 2, for example with screws.

[0046] Further reinforcing elements are formed by a further horizontal bar 33 and a box rail 15 anchored between the two bars 32 and 33 and anchored to the inner side of the panel 11, for example by gluing.

[0047] The further reinforcing elements can be omitted depending on the width of the panel, for example in the narrower vertical panel 12, which is however installed in the same manner as the panel 11, on the opposite side of the runway. Therefore, the panel 12 comprises, similarly to the panel 11, an upper bar 30' and a lower bar 32', and a square 31'.

[0048] Two box elements 34, 35 are inserted vertically at opposite sides of the horizontal panel 10, in the bends 22, 23. Squares 36, 36' are anchored to the box elements. The horizontal panel 10 is installed in the same manner as the vertical ones, first hung on the crosspiece 1 through the squares, then anchored to the crosspiece and to the vertical panels.

[0049] After installation of the panels, appropriate beading strips are inserted at the edge to cover the gaps remaining between the wall and ceiling edges, and the external edges of the panels.

[0050] L-shaped beading strips 17 are inserted at the vertical edges.

[0051] A horizontal crosspiece 16, with C-shaped profile with folded edges, internal on the upper edge and external on the lower edge, is firstly installed on the upper edge of the panels, starting from the side of the runway. The horizontal crosspiece 16 is anchored with rivets to the upper end of the panels 10, 11, and 12, and contributes towards the alignment thereof.

[0052] An L-shaped beading strip 18 is then inserted, anchored to the upper side of the crosspiece 16. The enlargement of the profiles of the crosspiece 16 and of the beading strip 18 can be seen in the enlargement of Fig. 5.

[0053] A vertical stop 40, to stop the doors in closed position, and a horizontal element 41 can also be present laterally.

[0054] It can easily be noted that the infill is composed of panels with anchoring system to the structural part that allows them to be substituted in time with a simple and rapid operation without work on the structural part, on the suspensions and on the landing door panels which remain installed also during this operation.

[0055] Therefore, a single panel, several panels or all the entire infill can be replaced at any time without any work on the elevator system.

[0056] The use of infill panels also simplifies positioning of the elevator call button, as it can be produced directly on the infill panel. See, for example, Fig. 6 in which the call buttons 28 are installed directly on the panel 11.

[0057] By a preliminary operation of the elevator mounting team to position said jig and said upper crosspiece, there are advantages in terms of:

• certainty of the tolerances of the finishes,
• simple subsequent mounting of the elevator
• quality of execution of the works as a whole,
• simple blocking off of the elevator runway during building finishing works.

[0058] The mounting method of the invention makes it possible, for the entire time rqeuired for this mounting, to avoid masonry works, as work takes place with the runways fully open at the floors.

[0059] Moreover, even if said jig 2 and said upper crosspiece 1 are soiled by building finishing works, they are not destined to remain in view.

[0060] The system of the invention also allows installation of door openings on different sides at the various floors, in the case in which it is necessary to provide the elevator car with doors on more than one side, for door opening on different sides at different floors of the building.

[0061] Although the present description refers explicitly to an elevator, the same concepts can also be applied to any lift system having the same problems as elevators. Variants of embodiment to the non-limiting example described are possible, without departing from the scope of protection of the present invention, comprising all equivalent embodiments for those skilled in the art.

[0062] The advantages deriving from application of the present invention are apparent. Besides those already listed above, the following can also be mentioned.

[0063] There are evident advantages for the firm installing the elevator system:

• absence of interaction and, consequently, independence from the programming of the building firm;
• simplicity, with automatic positioning of the suspensions of the landing: only centering must be checked;
• the elevator system can be sold complete with all its parts including the infill panels of the elevator runway with a customized system in modules;
• after sales management: any request from the customer to change the construction and finishing material can be satisfied, by replacing the panels at any time in a simple, rapid and consequently inexpensive manner, without work on any component of the elevator system;
• no time lost in general cleaning and for checking system operation of equipment soiled by the finishing material of the building firm;
• hand-over of the system to the customer in perfect finished condition.

[0064] There are also advantages for the building firm:

• it is no longer necessary to construct customized jambs and headers;
• finishing operations are no longer necessary after installation of the doors of each landing by the firm installing the elevator system;
• the structural part is used as jig to apply the plaster or other type of finish and lay the floors;

[0065] it is possible to finish the building completely, with regard to the floor and also paint the stairwell, having installed only the mechanical part of the elevator system and the structural part of the system.

[0066] There are also advantages for the building planner:

• no information is required for positioning of jambs or lowering of the header during planning of the elevator runway.

[0067] Moreover, the advantages in terms of safety are evident:

• the system is designed for installation of supports for laying wooden planks to protect against falling into the elevator runway;
• the supports for installation of the wooden planks have standard thickness necessary to prevent falling into the elevator runway;
• the system also comprises the standard safety sign to install at the center of the top wooden plank indicating falling hazard;
• the building firm only needs to provide the wooden planks, without also having to worry about how these are anchored.

[0068] From the description above those skilled in the art are able to produce the subject of the invention without introducing further constructional details.
