DESCRIPTION

Description of the INDUSTRIAL INVENTION entitled:

?Inspection hatch of a roller shutter box and roller shutter box including said inspection hatch?

Field of application of the invention

The present invention finds application in the window and door frames sector. More precisely, the present invention concerns external roller shutter frames for closing doors and windows. Said frames are commonly referred to as ?roller shutters? or ?roller blinds?. As is known, roller shutters comprise a plurality of slats arranged horizontally and connected to each other so as to be rollable around a drive shaft generally called a ?roller? and located above the space (door or window) that the roller shutter is intended to reversibly close. The roller of a roller shutter is housed in a seat, commonly referred to as a ?box?, obtained in the wall where the space that the roller shutter is intended to reversibly close is made.

The present invention relates, in particular, to an inspection hatch for a roller shutter box. The present invention also relates to a roller shutter box equipped with the aforementioned hatch.

Incidentally, by stating that a roller shutter reversibly blocks a space, it is meant that the space can be unblocked by the roller shutter (by rolling up the slats on the roller) and re-blocked by the roller shutter (by unrolling the slats from the roller) an indefinite number of times.

Review of known art

As previously mentioned, roller shutter boxes generally include a cavity made in the wall where the space that the roller shutter is intended to reversibly close is made. The box is large enough to contain, in addition to the roller, almost all of the slats when wrapped around the roller (i.e. when the roller shutter is completely raised). The box is usually substantially rectangular in shape with: the height arranged horizontally and parallel to the roller shutter slats, the two bases arranged vertically and orthogonally to the roller shutter slats, two of the four side walls, one lower and one upper, arranged horizontally and the remaining two side walls, one facing outwards and one facing inwards of the building equipped with the space that the roller shutter is intended to reversibly close, arranged vertically. Generally, the box is large enough to contain, in addition to the roller, almost all of the slats when wrapped around the roller (i.e. when the roller shutter is completely raised). delimited by the wall corresponding to the aforementioned bases, the aforementioned upper wall and the aforementioned wall facing the outside of the building (equipped with the space that the roller shutter is intended to reversibly close). Corresponding to the two remaining walls (one lower and the other facing the inside of the building) the box instead comprises two respective panels made for example of polymeric material or wood. The panel corresponding to the aforementioned lower wall can be classified as a "lower panel" while the panel corresponding to the aforementioned wall facing the inside of the building can be classified as a "front panel".

The lower panel of the box generally has a lengthwise through hole (i.e. a slot) through which the roller shutter slats slide with each rotation of the roller. The front panel is usually removable to allow access to the box (for example, to carry out maintenance on the roller or on the roller shutter components connected to it). More precisely, the front panel is generally inserted into a rectangular frame to which the front panel is reversibly connected by interlocking. The front panel and the frame to which it is connected form, possibly with other elements, the inspection panel of the box.

Incidentally, by stating that the front panel is reversibly connected to the frame, it is meant that the panel is disconnectable from the frame and reconnectable to it an indefinite number of times.

The fact that the front panel is connected to the frame by interlocking means that the operation of opening the inspection door of a roller shutter box is usually carried out by partially inserting a rod (for example a screwdriver) into the gap between the front panel and the frame, and expelling the panel from the frame by levering it using the aforementioned rod. This opening operation is, however, difficult. In addition to this, repeated execution of this operation risks damaging the inspection door of the box.

Purposes of the invention

The purpose of the present invention is to overcome the above-mentioned drawbacks by providing an inspection door for a roller shutter box that can be opened more easily than known doors of the same type.

Summary and advantages of the invention

The object of the present invention is an inspection door for a box suitable for housing at least a plurality of slats of a roller shutter and a roller for moving said slats of said roller shutter,

said counter comprising:

? a panel delimited by a border;

? a frame including:

? multiple internal faces adjacent to each other to form a closed path (i.e. schematized by a closed line). Incidentally, two faces of a solid are said to be adjacent if they share an edge.

Said frame, corresponding to said internal faces, delimiting, at least partially, a portion of space;

? a front face adjacent to said internal faces;

? a rear face opposite to said front face and also adjacent to said internal faces so that the latter, as a whole, are interposed between said front face and said rear face,

? a recess made in said frame where said internal faces are adjacent to said front face (i.e. made in the frame where the internal faces would be adjacent to the front face if the recess were not there), so that said recess is accessible at said internal faces and at the same time at said front face,

said recess extending so as to form a closed path surrounding said portion of space,

said recess has a bottom (i.e. the wall or walls that delimit the cavity (i.e. the hollow, the concavity) of the recess) also delimiting, at least partially, said portion of space,

said edge being housed, at least partially, in said recess,

the at least partial housing of said edge in said recess causing said panel to be at least partially housed in said portion of space such that said panel is framed in said frame,

said panel being:

? unmountable from said portion of space, and therefore removable from said frame,

And

? after having been dislodged from said portion of space, re-lodable in said portion of space, and therefore re-frameable in said frame,

multiple times,

said edge being dislodgable from said recess, thus causing said panel to be dislodged from said portion of space, moving said panel away from said rear face, exiting from said recess in correspondence with said front face,

said edge, after having been dislodged from said recess, being re-locatable, at least partially, in said recess, so as to determine at least partial re-housing of said panel in said portion of space, moving said panel towards said rear face, accessing said recess in correspondence with said front face,

wherein, according to the invention, said edge is housed in said recess in such a way that said panel is not wedged in said frame,

said door comprising reversible connection means between said panel and said frame,

said means of connection being such that said panel is:

? disconnectable from said frame

And

? after being disconnected from said frame, when said edge is housed in said recess, reconnectable to said frame by means of said connection means,

multiple times,

said edge being dislodgable from said recess following a disconnection of said panel from said frame.

The inspection door panel of the invention, being not embedded in the frame, can be dislodged from the latter by simply disconnecting the panel from the frame and extracting the panel from the frame by, for example, moving it orthogonally to the front face of the frame, away from the rear face of the latter.

Other innovative features of the present invention are illustrated in the following description and referred to in the dependent claims.

According to one aspect of the invention, said door comprises a gasket that is at least partially air and water tight,

said gasket being:

? housed in said recess so as to be clamped between said panel and said frame,

? connected to said frame

and

? extended in length forming a closed path surrounding said portion of space.

According to this aspect of the invention, the gasket advantageously opposes an unwanted passage of air and water from the inside of the box of a roller shutter of which the door in question is a part to the interior of the building equipped with the space that the roller shutter is intended to reversibly block, and vice versa. By way of example, during the winter period, the gasket advantageously opposes an (undesirable) passage of cold air from the inside of the box to the interior of the building, and an (undesirable) passage of hot air from the interior of the building to the inside of the box. Again by way of example, during the summer period, if the interior of the building is air conditioned, the gasket advantageously opposes an (undesirable) passage of hot air from the inside of the box to the interior of the building, and an (undesirable) passage of cold air from the interior of the building to the inside of the box. In addition to what has been said, if the roller shutter slats are wet, the gasket advantageously prevents the passage of water from inside the box to the internal environment of the building.

According to another aspect of the invention, said reversible connection means comprises at least one screw comprising a head and a shank extending from the latter,

said stem crossing said panel and penetrating said frame, said head and said frame lying on opposite sides with respect to said panel (the latter is therefore interposed between the frame and the head of the screw),

said stem being reversibly screwed at least into said frame such that said head clamps said panel against said frame with the interposition, if present, of said gasket, thus reversibly connecting said panel to said frame.

Incidentally, by stating that the stem is reversibly screwed into the frame, it is meant that the stem can be unscrewed from the frame and screwed back into the frame an indefinite number of times.

According to another aspect of the invention, said fund comprises:

? a first section facing said portion of space;

? a second section extending from said first section to said portion of space.

According to another aspect of the invention, said gasket is clamped between said panel and said second section of the bottom of said recess.

According to another aspect of the invention, said stem penetrates said frame at said recess and passes through said second section of the bottom of said recess.

According to another aspect of the invention, said internal faces are orthogonal to said front face.

According to another aspect of the invention, said first section of the bottom of said recess is orthogonal to said front face,

said second section of the bottom of said recess being parallel to said front face.

According to another aspect of the invention, said frame comprises a plurality of bars connected to each other at their ends so as to be consecutive to each other,

each bar of said plurality comprising:

? an internal face facing said portion of space;

? a front face adjacent to said inner face of said bar;

? a rear face opposite said front face of said bar and adjacent to said internal face of said bar so that the latter is interposed between said front face of said bar and said rear face of said bar;

? a recess formed longitudinally in said bar where said inner face of said bar and said front face of said bar are adjacent to each other (i.e. formed in said bar where the front face of said bar would be adjacent to the inner face thereof if the recess were not present), so that said recess is accessible at said inner face of said bar and at the same time at said front face of said bar,

the bars of said plurality being consecutive to each other in such a way that:

? the internal faces of said bars correspond to said internal faces of said frame,

? the front faces of said bars form, together, said front face of said frame,

? the rear faces of said bars form, together, said rear face of said frame

And

? the recesses of said bars form a closed path giving rise, in their entirety, to said recess of said frame.

Another object of the invention is a box comprising a cavity where at least a plurality of slats of a roller shutter can be housed and a roller for moving said slats of said roller shutter,

said container also including the inspection door which is the subject of the invention,

said cavity being partially delimited by said door,

a dislodging of said edge of said panel of said door from said recess in said frame of said door allowing access to said cavity.

Detailed description of some preferred embodiments of the invention

In the following description, a figure may also be illustrated with reference to elements not expressly indicated in that figure but in other figures. The scale and proportions of the various elements depicted do not necessarily correspond to the real ones.

Figures 1 and 2 show an inspection door 1, the subject of the invention, which can be equipped with a roller shutter box to allow access to the cavity of the box housing, by way of example, a plurality of roller shutter slats and the movement roller of said slats.

The door 1 comprises a panel 2 preferably substantially rectangular parallelepiped. The length and width of the panel 2 (parallel to the plane of the sheet in figure 1) are preferably prevalent with respect to the thickness of the same (orthogonal to the plane of the sheet in figure 1). More precisely, the panel 2 is preferably delimited by a front face 3 (parallel to the plane of the sheet in figure 1 and facing the observer in figure 1), a rear face 4 (parallel to the plane of the sheet in figure 1) opposite the face 3 and four lateral faces 5 (orthogonal to the plane of the sheet in figure 1) interposed between the faces 3 and 4. The latter (the faces 3 and 4) are preferably equal to each other and mutually parallel. Each of the faces 3 and 4 has a prevalent extension on each of the faces 5. The four faces 5 are adjacent to each other to form a closed path and together constitute the edge of the panel 2. The panel 2 is preferably at least partially made of sintered expanded polystyrene (also known by the acronym ?EPS?).

The panel 2 is framed in a frame 6 preferably substantially shaped like a rectangular parallelepiped with a central through hole which is also preferably substantially a rectangular parallelepiped. Similarly to what was said for the panel 2, the frame 6, not considering the aforementioned central hole, has a length and a width (parallel to the plane of the sheet in figure 1) preferably prevailing over the thickness of the frame 6 (orthogonal to the plane of the sheet in figure 1). The aforementioned central hole also has a length and a width (parallel to the sheet in figure 1) prevailing over the depth of the hole (orthogonal to the plane of the sheet in figure 1 and equal to the aforementioned thickness of the frame 6). Schematizing both the aforementioned central hole and the frame 6 not considering the aforementioned central hole as, respectively, a first and a second rectangle, the diagonals of the first rectangle are preferably coincident with the diagonals of the second rectangle. The long sides of the first rectangle are therefore preferably parallel not only to each other but also to the long sides of the second rectangle, and the short sides of the first rectangle are preferably parallel not only to each other but to the short sides of the second rectangle.

The frame 6 is preferably delimited by a front face 7 (parallel to the plane of the sheet in figure 1 and facing the observer in figure 1), a rear face 8 (parallel to the plane of the sheet in figure 1) opposite the face 7, four external faces 10 (orthogonal to the plane of the sheet in figure 1) and four internal faces 11 (orthogonal to the plane of the sheet in figure 1). Each of the faces 7 and 8 has a prevalent extension on each of the faces 10 and 11. Each of the faces 10 is opposite one of the faces 11. The faces 10 are adjacent to each other to form a closed path and constitute, together, the external edge of the frame 6. The faces 11 are also adjacent to each other to form a closed path and constitute, together, the internal edge of the frame 6. The faces 11 delimit, at least partially, a portion of space corresponding to the aforementioned central through hole. Face 7 is adjacent to both faces 10 and faces 11. Similarly, face 8 is adjacent to both faces 10 and faces 11. In light of the above, both face 7 and face 8 are interposed between faces 10 and faces 11. Faces 10, as a whole, are therefore interposed between face 7 and face 8. Similarly, faces 11, as a whole, are interposed between face 7 and face 8. Faces 7 and 8 are preferably parallel to each other. Faces 10, as well as faces 11, are preferably substantially orthogonal to faces 7 and 8. Each of the faces 10 is preferably orthogonal to the two faces 10 to which it is adjacent. Similarly, each of the faces 11 is preferably orthogonal to the two faces 11 to which it is adjacent.

A recess 9 is created in the frame 6 where the faces 11 are adjacent to the face 7, i.e. in correspondence with each of the four edges respectively of the four faces 11 common to the face 7. More precisely, the recess 9 is created in the frame 6 where the faces 11 would be adjacent to the face 7 if the recess 9 were not there. The recess 9 therefore extends into the frame 6 along the internal edge of the latter, i.e. in such a way as to surround the aforementioned central through hole forming a closed path substantially shaped like the perimeter of a square or a rectangle. Since the recess 9 is created in the frame 6 where the faces 11 are adjacent to the face 7, the recess 9 is accessible in correspondence with the face 7 and at the same time the faces 11. The recess 9 is that is open at both face 7 and faces 11. The recess 9 has a bottom preferably comprising a first section 12 facing the aforementioned central through hole and a second section 13 extending from section 12 to the aforementioned central through hole. Section 12 is preferably orthogonal to faces 7 and 8 (mutually parallel) and section 13 is preferably parallel to said faces 7 and 8. Incidentally, the bottom of the recess 9 (and therefore sections 12 and 13 thereof) delimit, at least partially, the aforementioned central through hole of the frame 6.

As can be seen in figure 2, the edge 5 of the panel 2 is housed, at least partially and preferably completely, in the recess 9 in such a way that the panel 2 is framed in the frame 6. More precisely, the faces 3 and 4 of the panel 2 are preferably parallel to the faces 7 and 8 of the frame 6 and to the section 13 of the bottom of the recess 9. The faces 5 of the panel 2 are preferably respectively opposite (and therefore parallel) to the four portions into which the section 12 of the bottom of the recess 9 can be divided, respectively corresponding to the four sides of the square or rectangle, as the perimeter of which can be substantially schematized as the closed path described by the recess 9 around the aforementioned central through hole. A peripheral portion of the face 4 of the panel 2 adjacent to the four faces 5 and describing a closed path is opposite (and therefore parallel) to the section 13 of the bottom of the recess 9.

The housing of the edge 5 of the panel 2 in the recess 9 of the frame 6 causes the panel 2 to be at least partially housed in the aforementioned central through hole of the frame 6, that is, it causes the panel 2 to be framed in the frame 2. The edge 5 of the panel 2 can be dislodged from the recess 9, thus causing the panel 2 to be dislodged from the aforementioned central through hole of the frame 6 and therefore the panel 2 to be removed from the frame 6, exiting from the recess 9 in correspondence with the face 7, preferably translating orthogonally to the latter (i.e. to the plane of the sheet in figure 1) away from the face 8. By equipping the door 1 with a roller shutter, the dislodgement of the edge 5 from the recess 9 allows access to the cavity of the roller shutter housing, for example, a plurality of roller shutters. of roller shutter slats and the movement roller of said slats.

The edge 5 of the panel 2, after being dislodged from the recess 9, can be re-located, at least partially, in said recess 9, thus determining an at least partial re-housing of the panel 2 in the aforementioned central through hole of the frame 6 and therefore a repositioning of the panel 2 in the frame 6, moving the panel 2 towards the face 8, accessing the recess 9 in correspondence with the face 7 preferably by translating the panel 2 orthogonally to the latter (i.e. moving the panel 2 towards the face 8 preferably orthogonally to the plane of the sheet in figure 1).

The edge 5 of the panel 2 can be dislodged from the recess 9 and, after having been dislodged from the recess 9, can be at least partially re-located in said recess 9 multiple times.

Door 1 differs from known doors of the same type in that edge 5 is housed in recess 9 in such a way that panel 2 is not wedged into frame 6. Panel 2 is kept housed in frame 6 by means that reversibly connect panel 2 to frame 6. More precisely, said reversible connection means are such that panel 2 can be disconnected from frame 6 and, after being disconnected from frame 6, when edge 5 is housed in recess 9, reconnected to frame 6 (via said connection means) multiple times. Incidentally, edge 5 of panel 2 can be dislodged from recess 9 following disconnection of panel 2 from frame 6.

The aforementioned reversible connection means preferably comprise one or more screws 14. The latter are shown by way of example in a number equal to four. Each of the screws 14 comprises a head and a shank extending from the latter. The shank of each of the screws 14 passes through the panel 2 preferably orthogonally to the faces 3 and 4 and penetrates the frame 6 preferably in correspondence with the recess 9 passing through the section 13 of the bottom of the same. The head of each of the screws 14 and the frame 6 (and more precisely the section 13) lie on opposite sides with respect to the panel 2. The shank of each of the screws 14 is screwed reversibly at least into the frame 6 in such a way that the head of said screw 14 tightens the panel 2 against the frame 6 and more precisely against the section 13 of the bottom of the recess 9, thereby reversibly connecting the panel 2 to the frame 6.

The four screws 14 penetrate the panel 2 preferably respectively in proximity to the four vertices of the face 3, at a distance from the edge 5 such that the shank of each screw 14 penetrates the section 13 of the bottom of the recess 9 of the frame 6.

As can be seen in figure 2, the door 1 preferably comprises a gasket 15 that is at least partially air and water tight. The gasket 15 is housed in the recess 9 so as to be tightened between the panel 2 and the frame 6, is preferably connected to the latter and is extended in length to form a closed path that surrounds the aforementioned central through hole (and therefore the panel 2 when partially housed in said hole, as shown in figures 1 and 2). Said closed path described by the gasket 15 is preferably substantially shaped like the perimeter of a square or a rectangle. The gasket 15 is preferably connected to the frame 6 at the section 13 of the bottom of the recess 9 and is tightened between the panel 2 and said section 13. Incidentally, the stem of each screw 14 is reversibly screwed at least into the frame 6 so that the head of said screw 14 tightens the panel 2 against the section 13 of the bottom of the recess 9 with the interposition of the gasket 15, if present. The shanks of the screws 14 and the section 12 of the bottom of the recess 9 preferably lie on opposite sides with respect to the gasket 15 (the latter is therefore interposed between the section 12 of the bottom of the recess 9 and the screws 14).

The frame 6 preferably comprises a plurality of bars 16 joined together at their ends so as to be consecutive to one another. Figure 3 shows one of the bars 16. The bars 16 are preferably present in a number equal to four. Each of the bars 16 is preferably opposite one of the faces 5 of the panel 2. Each of the bars 16 is therefore preferably arranged orthogonally to the two bars 16 to which it is consecutive. The bars 16 are preferably profiles made of polyvinyl chloride (also known by the acronym PVC) and each of them comprises an internal face 11a facing the central through hole of the frame 6 (i.e. towards the panel 2), a front face 7a adjacent to the face 11a, a rear face 8a opposite the face 7a and also adjacent to the face 11a (so that the latter is interposed between the face 7a and the face 8a) and an external face 10a opposite the face 11a and adjacent to the faces 7a and 8a (so as to be interposed between the latter). Each of the bars 16 includes a recess 9a formed longitudinally in said bar 16 where the face 11a of said bar 16 and the face 7a of said bar 16 are adjacent to each other (i.e. formed in said bar 16 where the face 7 of said bar 16 would be adjacent to the face 11a of said bar 16 if the recess 9a were not there), so that the recess 9a is accessible at the face 11a of said bar 16 and at the same time at the face 7a of said bar 16. The bars 16 are consecutive to each other in such a way that the faces 11a correspond to the faces 11, the faces 7a are adjacent to each other to form, as a whole, the face 7, the faces 8a are adjacent to each other to form, as a whole, the face 8, the faces 10a correspond to the faces 10 and the recesses 9a are consecutive to each other to form a closed path giving rise, as a whole, to the recess 9.

Each of the bars 16 has a section that is preferably substantially square or rectangular except for the portion of bar 16 that is "missing" due to the presence of the corresponding recess 9a.

As specified above, the bars 16 are preferably joined to each other at their respective ends so that each of the bars 16 is connected orthogonally, at its first end, to one end of another bar 16 and, at its second end opposite to said first end, to one end of yet another bar 16 parallel to said other bar 16. At its ends, each bar 16 ends with a section that is not orthogonal to the direction in which said bar 16 extends in length. In particular, observing each of the bars 16 from the side of face 8a, said bar 16 appears as an isosceles trapezium. The bars 16 are shaped in such a way that they are joined to each other in such a way that two bars 16 consecutive to each other have two oblique sides of the two isosceles trapeziums as they appear when observed from the side of face 8a, respectively, matching.

Figure 4 shows a roller shutter 20 comprising a plurality of slats 21 connected to one another to form a structure 22 that can be rolled up around a roller 23 suitable for moving said structure 22. In Figure 4, the structure 22 is shown partially wrapped around the roller 23. The latter, together with the slats 21 included in the portion of the structure 22 wrapped around the roller 23, is housed in a box 25.

The box 25 is located above the space (door or window) that the roller shutter 20 is suitable for reversibly closing. The box 25 includes a cavity 26. It is in correspondence with said cavity 26 that the roller 23 and the slats 21 included in the portion of the structure 22 wrapped around it are housed in the box 25. The cavity 26 is partially delimited by the door 1, included in the box 25. The door 1 allows access to the cavity 26 by dislodging the edge 5 of the panel 2 from the recess 9 of the frame 6 after having unscrewed the screws 14 enough so that the stem of the screws 14 no longer penetrates the frame 6 (and therefore enough so that the panel 2 is disconnected from the frame 6).

Based on the description provided for a preferred embodiment, it is obvious that some changes can be introduced by those skilled in the art without thereby departing from the scope of the invention as defined by the following claims.
