Abstract
Description
- The present invention relates to an industrial door.
- To close openings made through the masonry structure of an industrial shed, it is known to provide a door of the type comprising a plurality of vertical leaves that are slidably coupled or hinged to one another, a substantially horizontal guide fixed to the masonry structure above the leaves, and a conveying carriage, which is connected to one of the two end leaves, and is engaged to a chain conveyor for performing rectilinear displacements along the guide and displacing the leaves between an opening position and a closing position of the industrial door.
- Generally, the chain conveyor is wound to form an endless loop about a pair of sprocket wheels mounted so as to turn about respective longitudinal axes under the thrust of an electric motor fixed to the masonry structure on the outside of the guide of the conveying carriage.
- Known industrial doors of the above type have some drawbacks principally resulting from the fact that the chain conveyor is relatively noisy, involves frequent maintenance interventions, and is relatively cumbersome on account of the installation of the aforesaid electric motor on the masonry structure and on the outside of the guide of the conveying carriage.
- Document
DE 19932891 A1 relates to an industrial door comprising at least one leaf and actuator means for displacing the leaf between an opening position and a closing position of the industrial door itself. The actuator means comprise a carriage for advance of the leaf, a guide for guiding the carriage, and actuator means for advance of the carriage along the guide and in a given direction. The actuator means are carried by the carriage and comprise a motor mounted on the carriage for displacing the carriage itself along the guide. - It is an object of the present invention to provide an industrial door designed to eliminate the aforementioned drawbacks and that will be simple and inexpensive to produce.
- According to the present invention, there is provided an industrial door as claimed in the accompanying claims.
- The present invention will now be described with reference to the accompanying drawings, which illustrates a non-limiting example of embodiment thereof and in which:
-
Figure 1 is a schematic side view, with parts enlarged for reasons of clarity, of a preferred embodiment of the industrial door of the present invention; -
Figures 2 and3 are two schematic perspective views of a detail of the industrial door ofFigure 1 ; -
Figure 4 illustrates, in schematic perspective view, with parts enlarged for reasons of clarity, the industrial door ofFigure 1 in two different operating positions; and -
Figure 5 is a schematic perspective view of a variant of the industrial door ofFigure 1 . - With reference to
Figure 1 , designated as a whole by 1 is a door mounted to close anopening 2 made through themasonry structure 3 of an industrial shed. - The door 1 comprises a plurality of vertical plane leaves 4 (in the case in point, four leaves 4), which have a substantially rectangular shape, are hinged together in points corresponding to respective longitudinal edges parallel to a
vertical direction 5 so as to turn, with respect to one another and according to modalities that will be illustrated in greater detail in what follows, about correspondingaxes 6 of fulcrum parallel to thedirection 5, and comprise a first end leaf 4 (hereinafter designated by 4a), hinged to thestructure 3 so as to turn, with respect to thestructure 3, about an axis 7 of fulcrum parallel to theaxes 6, a second end leaf 4 (hereinafter designated by 4b), opposite to theleaf 4a, and two intermediate leaves 4 (hereinafter designated by 4c), arranged between theleaves - The door 1 moreover comprises a
guide 8, which has an elongated shape, extends above the leaves 4 in ahorizontal direction 9 transverse to thedirection 5, and is defined by a tubularsectional element 10, which is fixed to thestructure 3 above theopening 2, is substantially U-shaped with its concavity facing downwards, and comprises two longitudinal edges bent so as to define two horizontal plane tracks 11, set parallel to one another and to thedirection 9. - According to what is illustrated in
Figures 2 and3 , the leaves 4 are mobile between a closing position (Figure 1 ) and an opening position (Figure 4b ) of theopening 2 under the thrust of a conveyingdevice 12 comprising acarriage 13, which is mounted within theguide 8 and comprises, in turn, a supportingframe 14 provided with two mutuallyparallel axles frame 14 so as to turn, with respect to theframe 14 itself, about alongitudinal axis 17 thereof parallel to ahorizontal direction 18 orthogonal to thedirections wheels 19 engaged in the two tracks 11. - The
axle 15 is set in rotation about itown axis 17 by anactuator device 20 comprising anelectric motor 20a, which is mounted on theframe 14 and has an output shaft defined by ascrew 21, which extends parallel to thedirection 9, and meshes with ahelical gear 22, fitted on a supportingshaft 23 parallel to thedirection 18. Theshaft 23 is mounted in a coaxial position facing atransmission shaft 24 coupled, normally, in an angularly fixed way to theshaft 23 itself via the interposition of a clutch 25, in the case in point a clutch of an electrical type. - The
shaft 24 sets in rotation theaxle 15 via achain 26 of gears comprising afirst gear 27a fitted on theshaft 24 and asecond gear 27b fitted on theaxle 15 and coupled to thegear 27a itself. - The
carriage 13 is connected to theleaf 4b via a draggingrod 28, which extends downwards from thecarriage 13, has alongitudinal axis 28a parallel to thedirection 5, is coupled in a rotatable and axially slidable way, in a position corresponding to a bottom end thereof, to an outer longitudinal edge of theleaf 4b, and is provided with a substantially parallelepipedaltop bushing 29, which is fixed to a top end of therod 28 in a direction transverse to theaxis 28a and is slidably coupled to aguide 30 made in theframe 14 parallel to thedirection 9. - The
bushing 29 is moreover coupled via a screw/nut screw coupling, to ascrew 31 of acorresponding actuation device 32, which defines part of the conveyingdevice 12 and comprises anelectric motor 33, which is mounted on theframe 14 and has anoutput shaft 34 opposite to thescrew 21 of themotor 20a. Theshaft 34 extends parallel to thedirection 9 and is connected to thescrew 31 via abelt transmission 35 of a known type for setting thescrew 31 in rotation and imparting upon thebushing 29, and hence upon therod 28, rectilinear displacements along theguide 30 in thedirection 9. - Each
electric motor contact supply device 36 comprising a plurality ofguides 37 made of conductive material (in the case in point, two guides 37) fixed within thesectional element 10 parallel to thedirection 9, and a plurality ofelectrical contacts 38, which are also made of conductive material, are equal in number to thecorresponding guides 37, project upwards from thecorresponding motor corresponding guides 37 during advance of thecarriage 13 along theguide 8. - Operation of the door 1 will now be described with reference to
Figures 1 and4 starting from an instant in which: - the leaves 4 are arranged in their closing position of the opening 2 (
Figure 1 ); - the two
motors - the
bushing 29 is set in a point corresponding to one end of theguide 30 adjacent to the axle 16 (Figures 1-3 and4a ). - To open the door 1, the
carriage 13 is displaced along theguide 8 via theactuation device 20 so that, by combining the displacement of thecarriage 13 in thedirection 9 with the rotation of theleaves corresponding axes leaves Figure 4a ). Proper rotation of theleaves corresponding axes guide 8 and, for eachleaf - When the
carriage 13 reaches the end of theguide 8, the encumbrance of thecarriage 13 itself in thedirection 9 prevents complete and proper folding of theleaf 4b in contact with theadjacent leaf 4c (Figure 4a ). Folding of theleaf 4b, and hence opening of the door 1, is completed by activating theelectric motor 33 so as to displace thebushing 29, and hence thedragging rod 28, between the ends of theguide 30 in the direction 9 (Figure 4b ). - When the
bushing 29 reaches the end of theguide 30 adjacent to theaxle 15, completing folding of theleaf 4b, themotor 33 is deactivated in response to a signal coming from a sensor 39 (Figure 1 ) fixed to thestructure 3 for detecting complete opening of the door 1. - To close the door 1, the
carriage 13 is displaced along theguide 8 via theactuation device 20 so that, by combining the displacement of thecarriage 13 in thedirection 9 with the rotation of theleaves corresponding axes leaves - When the
carriage 13 reaches the end of theguide 8, the encumbrance of thecarriage 13 itself in thedirection 9 prevents complete and proper closing of theleaf 4b in contact with thestructure 3. Closing of theleaf 4b, and hence of the door 1, is completed by activating theelectric motor 33 so as to displace thebushing 29, and hence thedragging rod 28, between the ends of theguide 30 in thedirection 9. - When the
bushing 29 reaches the end of theguide 30 adjacent to theaxle 16, thus completing closing of theleaf 4b, themotor 33 is deactivated in response to a signal coming from a sensor 40 (Figure 1 ) fixed to thestructure 3 for detecting complete closing of the door 1. - The door 1 thus presents a number of advantages principally resulting from the fact that:
- the
entire actuation device 20 of thecarriage 13 is mounted directly on thecarriage 13 itself, has relatively small overall dimensions, and is relatively quiet; - the
actuation device 32 of thedragging rod 28 of theleaf 4b guarantees a complete and proper opening and closing of the door 1, in particular when the conformation of the opening 2 prevents installation of aguide 8 having a length, measured parallel to thedirection 9, greater than the width of theopening 2, which is also measured parallel to thedirection 9; and - the
clutch 25 enables, in the case of absence of supply of themotor 20a, decoupling of theshafts carriage 13 along theguide 8. - The variant of
