Definitions

• the object of the present invention is a spring closure system for an entrance door of a sectional door.
• Sectional doors which are used particularly for the closure of garages and similar premises, are made up of a plurality of superimposed sections which are reciprocally articulated along horizontal axes, so that the sectional door, when it is in the lowered condition, lies substantially in a vertical plane which blocks the entrance of the premises, when it is in the raised condition it lies substantially in a horizontal plane parallel to the ceiling of the premises, and in the passage from one to the other of these conditions it follows a curved trajectoiy, which is made possible by the articulations between the different sections.
• sectional doors in view of their function, have usually a considerable extension, and it is uselessly burdensome to raise the entire sectional door when it is necessary to allow only the passage of one or more persons. For this reason, in certain sectional doors an entrance door of small dimensions is formed, intended to be opened to allow the passage of persons, without raising the whole sectional door.
• the entrance door since the entrance door must have a height proportioned to the height of the persons, it has to extend for several sections of the sectional door, and therefore must also be made up of reciprocally articulated panels, in order to be able to follow the curved trajectoiy of movement of the sectional door.
• the entrance door is closed, with respect to the sectional door wherein it is formed, by means of an ordinaiy lock, which allows blocking of only one of the panels of the entrance door with respect to the corresponding section of the sectional door.
• an ordinaiy lock which allows blocking of only one of the panels of the entrance door with respect to the corresponding section of the sectional door.
• the entrance door is provided with a lock which blocks the panel whereon it is installed, as well as an upper latch and a lower latch.
• the mechanisms of these entrance doors have some disadvantages, and moreover the efficacy of the closure is not totally satisfactory.
• the mechanisms of the entrance door which has been opened are not presented as ready for a simple re-closure of the door without requiring a particular manoeuvre, in other words they allow the opening only from the exterior of the door.
• this closure system has to be designed for the particular sectional door whereon it has to be installed, not allowing an adaptability in situ on the basis of the dimensions of the sections of the door and of the panels of the entrance door.
• the object of the invention is that of eliminating the disadvantages of the known systems, ensuring for the entrance door a stable and resistant closure of all the panels whereof it is composed, likewise guaranteeing that, once it has been opened, it is presented as ready for being closed again without requiring any particular manoeuvre.
• Another object of the invention is that of providing such a closure system which has a limited bulk on the edge of the entrance door and therefore is aesthetically pleasing.
• Yet another object of the invention is that of allowing the adaptability to panels of the entrance door and sections of the sectional door of different height.
• Another object of the invention is that of allowing the assembly of the closure system indifferently on entrance doors with right or left opening.
• Last but not least an object of the present invention is that of providing such a closure system which is simple and economical to manufacture and easy to assemble by the user. These objects are achieved by the closure system for an entrance door of a sectional door which has the features listed in the annexed independent claim 1.
• Substantially the closure system according to the invention wherein the entrance door is made up of a plurality of superimposed panels P reciprocally articulated along horizontal axes situated at the axes of articulation of the corresponding sections of the sectional door S, wherein each panel P of the entrance door is articulated along a vertical axis, on a side of hinging of the entrance door, to a corresponding section of the sectional door, and wherein a lock of the closure system is suitable for being mounted on a first panel of the entrance door to block the entrance door with respect to the sectional door, comprises operatively vertical shaft segments which can be moved, through the action of the lock, between an opening position and a closure position, said shaft segments terminating at their distal ends, in the closure position, at said axes of articulation of the first panel; at least for some other panels of the entrance door vertical shaft segments are provided, coaxial with said shaft segments of the first panel, said vertical shaft segments being connected to means of blocking of the

• Figure 2 is a perspective view of a lock and of a corresponding composite shaft device according to the present invention.
• Figure 3 is a view of the lock of Figure 2 in a direction perpendicular to the edge of the entrance door, i.e. parallel to the plane of the same;
• Figure 4 illustrates in a frontal view the system of gears which transmits the movement from the lock to the composite shaft
• Figure 5 illustrates in blown-up perspective a composite shaft segment with its containment casing and the blocking means present in each panel, as well as a stop block to be applied on the jamb of the sectional door, shown in a different perspective for greater clarity;
• Figure 6 illustrates the components of Figure 5 in an assembled condition, without the cover of the containment casing, with the composite shaft segment in a first position
• Figure 7 is a view like Figure 6, with the composite shaft element in a second position
• Figure 8 is a side profile view taken from the left side of Figure 7;
• Figure 9 is a section taken along the plane IX-IX of Figure 7;
• Figures 10, 11 and 12 are sections taken along plane A-A of Figure 6 or B-B of Figure 7 with some parts on view, illustrating the blocking means in different positions with respect to the corresponding stop block provided on the jamb of the sectional door, with which they co-operate;
• Figure 13 is a median section of the blocking means in the position of Figure 11.
• the reference S denotes a sectional door, whereof four sections are shown
• the reference P denotes an entrance door, which is formed in the four sections shown of the sectional door S, and therefore is in turn composed of four panels.
• the corresponding sections of the sectional door S have frame elements Kl, K2, K3 and K4.
• the panels of the entrance door P are articulated to the corresponding sections of the sectional door S, while at the other frame elements K2, K3 and K4 the opening of the entrance door P takes place.
• a lock L is applied to a first panel of the entrance door P to allow the closure and the opening of the entrance door P.
• the intent is that the closure by lock of the entrance door P takes place at a plurality of the frame elements K3, and preferably at all these frame elements.
• the lock L installed on a first panel PI of the entrance door has an operative member 1 which can be moved in a horizontal direction, parallel to the plane of the door, and a gears device D is provided, such as that shown by way of an example in Figure 4, which transforms the horizontal movement of the operative member 1 into a movement in vertical direction in opposite ways of two shaft segments 6.
• the gears device D given as an example comprises a double rack 2, connected to the operative member 1 of the lock L, and meshing with pinions 3 which in turn mesh with cogged wheels 4 which actuate two racks 5 connected to the shaft segments 6.
• the shaft segments 6 of the first panel PI terminate, at their distal ends, at the horizontal articulations of the first panel PI with respect to the other panels of the entrance door, denoted, for reasons of simplicity, again by reference P. Therefore, in this condition, the presence of the shaft segments 6 does not obstruct the relative rotation of the panels P, which has to be able to take place freely during the movements of the sectional door S.
• the other panels P of the entrance door also have vertical shaft segments, denoted by the same reference numeral 6, coaxial with said shaft segments 6 of the first panel, and the shaft segments of each panel P terminate at their ends, in the closure position of the lock L, at the axes of articulation of the same panel P, and the vertical shaft segments 6 of each panel P are axially aligned with the vertical shaft segments 6 of the adjacent panels.
• the whole of all the shaft segments 6 of the various panels P of the entrance door constitutes a composite shaft, which is interrupted at the articulations between the panels, so as not to obstruct the relative rotation between the panels P, but so as to behave like a continuous shaft in the lowered condition of the sectional door S.
• shaft segments 6 of the composite shaft In the above there is generic mention for reasons of simplicity of shaft segments 6 of the composite shaft. In actual fact, as will be explained in greater detail herein below, the shaft segments 6 are in turn broken down into several elements in order to simplify the assembly and the actuation of the closure system according to the invention.
• a segment 6 of the composite shaft is split into two parts 60, 60', each one of which, according to the invention, is in turn broken down into two further elements, which will also be referred to as latches, 61, 62 and 6 , 62', respectively.
• latches are placed on a flat base 70, appropriately perforated for the purposes which are to be mentioned herein below, closed by a cover 80, also provided with appropriate holes.
• the latches 61, 61 ' which are also to be referred to as fixed latches, are restrained by slotting or with other means to a central plate 90, which has a shaped aperture 91, which is arranged in alignment with a corresponding shaped hole 71 provided in the base plate 70, through which passes the head or catch 54 of the blocking means B, constituted in particular by a bolt 50, whose structure will be explained in greater detail herein below.
• the mobile latches 62, 62' which can slide thereon in order to allow a regulation of the length of the corresponding assembled latch 60, 60' and therefore an adaptation to panels P of the entrance door of different height.
• the latches 61, 62 and 6 , 62' remain engaged in the required position by means of pairs of teeth provided on the respective opposite faces, whereof those provided on the fixed latches 61, 6 are just visible and denoted by reference numerals 63, 63'.
• the blocking of these elements taking place by means of pairs of screws in 81 , which traverse respective slots 82 provided in the cover 80, and a respective longitudinal slit 64, 64' provided in the mobile latches 62, 62', in order to screw in corresponding holes formed in the fixed latches 61 , 61 '.
• the components 61, 62, 61 ', 62' and 90 constitute a single segment composite shaft of actuation of the closure system according to the invention.
• the aforesaid components are closed between the base 70 and the cover 80 which form a casing which is attached by means of screws to the edge of the entrance door P.
• the cover 80 of the casing also has a hole 83 at the holes 91 and 71 provided respectively in the plate 90 and in the base 70, for the passage of the bolt head 51.
• the mobile latches 62, 62' have the ends 65, 65' projecting from the containment casing misaligned so as to be placed on one side of the casing, rather than centrally thereto, in order to be situated on the inner side of the edge of the entrance door in assembled position, and in this way to allow an easy opening of the sectional door.
• FIGS. 6 to 9 show a casing of containment of the components of Figure 5 for door with opening on the right as shown in Figure 1, and positioned at one of the panels of the entrance door P placed below the one carrying the lock L, or on the same panel PI carrying the lock L, when the blocking means B are placed below the lock, as shown in the drawings.
• Figure 6 shows the position of the latches, in other words of the composite shaft segment in the closed door condition, with the bolt 50 blocked
• Figure 7 shows the configuration of the latches in the phase of opening of the entrance door, i.e. with the bolt unblocked, as will be explained in greater detail herein below.
• the bolt 50 comprises a tubular casing 52 which is inserted in the edge of the entrance door and encloses the entire mechanism of actuation of the bolt. More particularly, in the casing 52 a slider 53 is placed, acting as an actual bolt, carrying at the end the bolt head or catch 54, mounted oscillating around a pin 55, under the action of a spring 56 ( Figure 13), which tends to hold the head 54 in the position of blocking shown in Figures 11 and 13.
• the slider 53 is pushed in a rest position, corresponding to that of blocking of the bolt head 54, by a spring 57.
• the rest position of the slider 53 in other words the blocking position of the bolt head 54, is ensured by a tooth 41 provided on the slider which engages in a corresponding seat 42 of an L-shaped balancing lever 43, hinged in 44 to the casing 52.
• a longer arm 45 of the lever 43 extends longitudinally to the interior of the casing 52 whereto it is hinged, while the shorter arm 46 projects laterally from the casing 52.
• a projection 47 is provided, oriented substantially parallel to the short arm 46 of the lever 43, against which acts a spring 48, suitable for holding the lever 43 normally engaged with the tooth 41, in position of blocking of the bolt.
• lever 43 has been simplified for reasons of clarity.
• the lever 43 is double and the short arms 46 are joined one to the other at the free ends, and the tooth 41 is double and is constituted by a transverse bar which goes to engage in the cavities 42 of the double lever.
• the projection 47 at the end of the aim 45 is constituted by a bar which joins the ends of the two arms of the double lever.
• the projecting arm 46 of the lever 43 is positioned flush with the perforated plate 90 of the latch, inside the shaped aperture 91, which has a wider central section 92, wherein the projecting arm 46 of the L-shaped lever 43 ( Figure 6) is freely housed and a narrower end section 93, defined by a cam profile 94 provided on an edge of the aperture 91, in the upper part of the plate 90 with reference to Figures 6 and 7.
• the perforated plate 90 is held in the rest position of Figure 6 by a spring 95, which acts between this plate and a fixed striker 59, made integral with the base plate 70 of the casing.
• the stop block 13 has a housing 12 suitable for holding the bolt head 54, said housing 12 being defined on the outer side of opening of the entrance door P by a bevelled jut 11, against which the oscillating bolt head 54 abuts in conditions of closed door, in other words of blocked bolt ( Figure 11).
• a possible push of the door in the direction of opening i.e. of movement of the bolt 50 towards the left with respect to the stop block 13 of Figure 1 1 , would cause the jamming of the bolt head 54 against the jut 1 1, any movement of the slider 53 being prevented by the engaging of the L-shaped lever 43 with the projection 41.
• the closure system according to the invention is easy to install, causing a minimal bulk on the edge of the entrance door, in that the casing 52 of each bolt 50 is housed inside the entrance door, from the edge whereof projects substantially only the bolt head 54, in addition to the casing of containment of the latches, constituted by the base 70 and by the cover 80 which is strongly flattened.
• closure is of the reversible type, it being possible, in the installation phase, to assemble the latches in inverted position according to right or left opening of the entrance door.
