[0043] Detailed description of some preferred embodiments

[0044] With reference to the figures mentioned above, herein described is a system 1 for the rotatable fastening of at least one closing element D, such as a door or the like, to a floor F and to an upper stationary support structure C, such as a ceiling or a crosspiece of a frame or counter-frame.Preferably, the rotary movement of the closing element D with respect to the floor F and to the upper stationary support structure C may be carried out around a main rotation axis Y', but it may also be carried out around an axis substantially parallel thereto by means of suitable guide elements, in a per se known manner.

[0045] It is clear that although hereinafter reference will be made, for the sake of simplicity, to the closing element D such as to a door and to the upper stationary support structure C such as a ceiling, such example shall not be deemed to be limiting for the invention.

[0046] In its simplest form, the rotatable fastening system 1 may include a device 100 for fastening the door D to the floor F and a unit for fastening the door D to the ceiling C.

[0047] More particularly, the device 100 for fastening the door D to the floor F may be adapted to house a lower pin Pl protruding from the door D, while the fastening unit may include a device 200 for fastening the door D to the ceiling C adapted to house an upper pin P2 protruding from the door D.

[0048] Even more particularly, for example as shown in FIG. 11, the upper pin P2 may be an integral part of a device 300 for coupling the door D to the ceiling C, as better shown hereinafter.

[0049] Although hereinafter reference will be made to such configuration, it is clear that the rotatable fastening system 1 may have any configuration without departing from the scope of protection of the attached claims.

[0050] For example, one or more of the fastening 100, 200 or coupling 300 devices may be replaced by equivalent components.

[0051] By way of non-limiting example, the two fastening devices 100, 200 may be used with the coupling device obtained according to the disclosure of the international application W02023 / 002387 on behalf of the Applicant in question, or the coupling device 300 may be used with the device for fastening to the floor and to the ceiling provided according to the disclosure of the international application.

[0052] In a further example, the system 1 may be without the coupling device 300, and the pins Pl, P2 may be integrally joined with the door D or it can be an integral part of hydraulic hinge, for example the one obtained according to the disclosure of the international application W02020 / 079496 on behalf of the Applicant in question.In a further example, the system 1 may include fastening devices 100, 200 and two coupling device 300, one arranged above and one below the door D.

[0053] The individual fastening 100, 200 and coupling 300 devices are described below. The device 100 for fastening the door D to the floor F may generally comprise a platelike base element 110, a slidable plate-like element 120 coplanar with the latter and an oscillating plate-like element 130 coplanar with the slidable plate-like element 120 and provided with a central seat 131 counter-shaped with respect to the lower pin Pl to house the same.

[0054] In particular, the plate-like base element 110 may be fixed to the floor F by means of suitable dowels 111 and it may be provided with a central seat 112, which is designed to house the slidable plate-like element 120.

[0055] More particularly, the latter may slidably move along an axis X lying on the plane nl defined by the plate-like base element 110 of substantially parallel to such plane nl.

[0056] To this end, as particularly shown in FIG. 3, the central seat 112 may have a pair of guide walls 113', 113" substantially parallel to the axis X, while the slidable plate-like element 120 may have a pair of abutment walls 122', 122" arranged in contact therewith.

[0057] The slidable plate-like element 120 may in turn be provided with a central seat 121 into which there may be inserted the oscillating plate-like element 130 to angularly rotate around the axis Y, which may be substantially perpendicular to the axis X and substantially parallel to the axis Y'.

[0058] To this end, the central seat 121 may have a circular segment-shaped abutment portion 123, while the oscillating plate-like element 130 may have a circular segment-shaped abutment portion 132 in contact with the circumferential arc guide portion 123 and concentrically coupled therewith to rotate around the axis Y.

[0059] The movements of the slidable plate-like element 120 along the axis X and oscillating about the axis Y may be implemented by suitable actuator means, which can be controlled by an operator. This will allow to adjust the position of the door D with respect to the floor F and the ceiling C simply and quickly.

[0060] In particular, the movement of the slidable plate-like element 120 along the axis X may be carried out in a controlled manner by the adjustment element 140, which may be athreaded bar, which may extend along the axis X to pass through the plate-like base element 110 at the passage portions 114', 114", through the slidable plate-like element 120 at the passage portions 124', 124", and through the oscillating plate-like element 130 at the passage portion 133.

[0061] Advantageously, the adjustment element 140 may be operatively engaged with the slidable plate-like element 120 and operatively disengaged from the plate-like base element 110 and by the oscillating plate-like element 130. For example, in the case of the adjustment element 140 in form of a threaded bar, the passage portions 124', 124" may be threaded, while the passage portions 114', 114" and 133 may be smooth.

[0062] In this manner, by acting on the adjustment element 140 the operator may promote the sliding of the slidable plate-like element 120 along the axis X with respect to the platelike base element 110.

[0063] Suitably, during such action, the adjustment element 140 may remain slidably locked in the passage portions 114', 114" so as to rotate idle with respect to the plate-like base element 110.

[0064] To this end, the adjustment element 140 may have a length LI greater than the distance DI between the mutually proximal openings 115', 115" and smaller than the distance D2 between the mutually distal openings 116', 116".

[0065] Furthermore, the adjustment element 140, may have a diameter 4>1 substantially equal to the diameter of the openings 115', 115" and 116' and greater than the diameter 4>2 of the opening 116", so as to remain interposed between the bottom wall 117" arranged at the latter opening 116" and a locking element 117', for example a pin, arranged at the opening 116'.

[0066] Advantageously, the adjustment element 140 may be controlled through the opening 116".

[0067] In order to lock the sliding along the axis X of the slidable plate-like element 120 once suitably positioned by the operator, there may be provided for suitable locking grub screws 150', 150" arranged on opposite sides with respect to the central seat 121 parallel to the axis X to rest against the slidable plate-like element 120.

[0068] On the other hand, the movement of the oscillating plate-like element 130 aroundthe axis Y may be carried out in a controlled manner by the adjustment element 160, which may be a threaded bar.

[0069] The adjustment element 160 may extend along an axis X' substantially parallel to the axis X to pass through the slidable plate-like element 120 at the passage portions 125', 125" and through the oscillating plate-like element 130 at the passage portions 134', 134".

[0070] Furthermore, suitably, the oscillating plate-like element 130 may further comprise a cylindrical seat 135 interposed between the passage portions 134', 134" and a cylindrical drive element 136 inserted into the cylindrical seat 135, and it may pass through the drive element 136 at the passage portion 137.

[0071] Advantageously, the adjustment elements 140 e 160 may be positioned parallel to each other on opposite sides with respect to the central seat 131 for the pin Pl.

[0072] More particularly, the adjustment element 140 may be interposed between the central seat 131 and the circular segment-shaped abutment portion 132, while the adjustment element 160 may be arranged on the opposite side with respect to a median plane nM passing through the central seat 131. In particular, the median plane nM may be substantially parallel to the axes X, X' and Y.

[0073] Suitably, both the adjustment elements 140 and 160 may be controlled by the operator by acting on the same side, so that the adjustment of the position of the door D with respect to the floor F and to the ceiling C occurs simply with two actions only.

[0074] Advantageously, the adjustment element 160 may be operatively engaged with the oscillating plate-like element 130 and operatively disengaged from the slidable plate-like element 120.

[0075] For example, in the case of the adjustment element 160 in form of threaded bar, the passage portions 125', 125" and 134', 134" may be smooth, while the passage portion 137 may be threaded.

[0076] In this manner, by acting on the adjustment element 160, the operator may promote the oscillation of the oscillating plate-like element 130 around the axis Y with respect to the slidable plate-like element 120.

[0077] In order to allow such rotation, the adjustment elements 140 and 160 may be spaced apart with respect to the respective passage portions 133 and 134', 134" passing throughthe oscillating plate-like element 130. The interspace between the adjustment elements 140 and 160 and the respective passage portions 133 and 134', 134" it may be sufficient to allow the misalignment of the oscillating plate-like element 130 with respect to the adjustment elements 140 and 160.

[0078] Suitably, during such action, the adjustment element 160 may remain slidably blocked in the passage portions 125', 125" so as to rotate idle with respect to the slidable plate-like element 120.

[0079] To this end, the adjustment element 160 may have a length L2 greater than the distance D3 between the mutually proximal openings 126', 126" and smaller than the distance D4 between the mutually distal openings 127', 127".

[0080] Furthermore, the adjustment element 160, may have a diameter 4>3 substantially equal to the diameter of the openings 126', 126" and 127' and greater than the diameter 4>4 of the opening 127", so as to remain interposed between the bottom wall 128" arranged at the latter opening 127" and a locking element 128', for example a pin, arranged at the opening 127'.

[0081] Advantageously, the adjustment element 160 may be controlled through the opening 127", which can be in turn obtained by means of a corresponding opening 118 passing through the plate-like base element 110.

[0082] In order to block the oscillation around the axis Y of the oscillating plate-like element 130 once suitably positioned by the operator, there may be provided for suitable locking grub screws 170', 170" arranged on opposite sides with respect to the central seat 121 parallel to the axis X to rest against the oscillating plate-like element 130.

[0083] The device 200 for the rotatable fastening of the door D to the ceiling C may generally comprise a base element 210 and a slider coupling element 220.

[0084] The base element 210 may include a plate-like fastening portion 211 which can be fastened to the ceiling C by means of dowels which can be inserted into the openings 212', 212" and a substantially cylindrical containment portion 213 which can be concealingly inserted into the ceiling C.

[0085] The slider coupling element 220 may be coaxially inserted into the containment portion 213 to move along the axis Y' between an inoperative position in which it does notprotrude from the plane n2 defined by the plate-like fastening portion 211 and an operative position in which it protrudes from the plane n2. Suitably, the slider coupling element 220 may internally comprise an anti-friction bushing 221, which is integrally joined movable with the slider coupling element 220.

[0086] To this end, in a preferred but non-exclusive embodiment, the slider coupling element 220 may be externally threaded, while the containment portion 213 may be internally counter-threaded.

[0087] In this manner, an operator may unscrew the slider coupling element 220 to move it from the inoperative position to the operative position, so as to compensate for any measurement errors regarding the height of the ceiling C with respect to the design measurements.

[0088] In order to block the position of the slider coupling element 220 once suitably positioned by the operator, there may be provided for suitable locking means, for example a pair of anti-rotation grub screws 230', 230" acting thereon and which can be fixed, for example which can be screwed, in the containment portion 212 in suitable fastening areas 214', 214" of the upper wall 215 thereof.

[0089] In order to perform their action, the anti-rotation grub screws 230', 230" may be inserted into suitable axial seats 231', 231" defined by axial recesses 221', 221" of the slider coupling element 220 and by a pair of axial grooves 216', 216" of the containment portion 212 once mutually faced. Suitably, both the axial recesses 221', 221" and the axial grooves 216', 216" may be internally smooth.

[0090] The device 300 for the removable rotatable coupling of the door D to the ceiling C may generally comprise a fixed base element 310 which can be fastened to the door D at a seat S, for example obtained by milling, and a substantially box-like movable element 320 defining a plane n3 which can be inserted into the seat S.

[0091] In particular, the seat S may be generally flat-shaped to slidably house the movable element 320 and it may be obtained at the upper end of the door D. In a preferred but nonexclusive embodiment of the invention, the seat S may remain faced to the fastening device 200.

[0092] The fixed base element 310 may be substantially plate-like to define a plane n4substantially perpendicular to the plane n3 defined by the movable element 320, and it may be fixed to the upper edge of the seat S by means of suitable screws or similar means passing through the openings 311.

[0093] Advantageously, the movable element 320 may be slidably coupled with the fixed base element 310 to move with respect thereto along an axis X" substantially parallel to the plane n3 or coplanar therewith.

[0094] To this end, in a preferred but non-exclusive embodiment, the fixed base element 310 may comprise a pair of axial recesses 312 extending parallel to the axis X" into which there be inserted respective guide pins 330. The latter may also be inserted into respective axial seats 321 of the movable element 320, so that the guide pins 330 are engaged both in the axial recesses 312 and into the axial seats 321 so as to guide the sliding of the substantially box-like movable element 320 with respect to the fixed base element 310 along the axis X".

[0095] Such movement may be carried out by suitable actuator means, for example an eccentric pin 340 which may include an upper operating end 341, an intermediate body 342 and an opposite eccentric end 343 suitably inserted into a cylindrical seat 322 of the movable element 320 to rotate therein, preferably by interposing an anti-friction bushing 323.

[0096] Advantageously, the operating end 341 may be inserted into a guide slot 313 of the fixed base element 310 defining an axis Z substantially perpendicular both to the axis X" and to the axis Y'.

[0097] In this manner, by acting with a special tool, for example a wrench, on the operating end 341, an operator may simply move the movable element 320 along the axis X".

[0098] Such movement may be carried out also with the door mounted, given that the operating end 341 may protrude from the slot 313 so as to remain above the fixed base element 310.

[0099] In order to block the position of the door D once suitably positioned by the operator, the intermediate body 342 may have an upper surface 344 designed to come into contact with a lower surface 314 of the fixed base element 310, therefore blocking the rotation of the eccentric pin 340 by friction.To this end, there may be provided for a pressing pin 350 engaged with the substantially box-like movable element 320 to act on the fixed base element 310 so as to force the lower surface 314 thereof against the upper surface 344 of the intermediate body 342 of the eccentric pin 340.

[0100] More particularly, the pressing pin 350 may include an upper operating end 351, an intermediate body 352 and an opposite end 353 which is suitably inserted into a cylindrical seat 324 of the movable element 320.

[0101] the intermediate body 352 may have a lower surface 354 designed to come into contact with an upper surface 315 of the fixed base element 310. In this manner, by acting on the operating end 351, the operator will force the lower surface 354 of the intermediate body 352 against the surface 315 of the fixed base element 310, which will lead the lower surface 314 of the latter to act against the upper surface 344 of the intermediate body 342 of the eccentric pin 340.

[0102] Advantageously, the substantially box-like movable element 320 may comprise a coupling pin P2 defining the axis Y', which may comprise a cylindrical base body 360 having a seat 361 and a plurality of axial recesses 362 substantially parallel to the axis Y'.

[0103] The coupling pin P2 may be movable integrally joined with the cylindrical base body 360 along the axis Y' between an inoperative position proximal to the bottom wall 325 of the movable element 320 and an operative position distal from the latter.

[0104] In the inoperative position P2, there may be positioned faced to the coupling element 200, that is along the axis Y', while in the operative position the coupling pin P2 may be inserted into the coupling element 200 so as to rotatably couple the door D with the ceiling C and constrain it to rotate around the axis Y' or an axis substantially parallel thereto.

[0105] Such movement between the inoperative and operative positions may be guided by a plurality of guide pins 363 each inserted into a respective axial cavity 362 and into a respective axial seat 326 of the working chamber 327 of the movable element 320.

[0106] In order to carry out such movement there may be provided for suitable actuator means, which in a preferred but non-exclusive embodiment may comprise an actuator pin 370 with an operating end 371 and a main cylindrical body 372 arranged in the working chamber 327 to rotate around an axis Y'" substantially parallel to the axis Y'.The main cylindrical body 372 may be operatively connected with the cylindrical base body 360 of the coupling pin P2 by means of a pin 373 having an end 373' inserted into the seat 361 and an opposite end 373" inserted into a helical slot 374 extending around the axis rrr

[0107] Advantageously, the main cylindrical body 372 may be slidably locked in the working chamber 327 so that it can only rotate around the axis Y'". To this end, the main cylindrical body 372 may be interposed between an upper abutment portion 328 of the working chamber 237 and a lower stop pin 329, which can be inserted transversely to the movable element 320.

[0108] In this manner, by acting with a special tool, for example a screw, an operator may rotate the actuator pin 370 around the axis Y'" to promote the sliding along the axis Y' of the cylindrical base body 360 of the coupling pin P2 between the inoperative and operative positions, and the resulting insertion of the coupling pin P2 into the coupling element 200.

[0109] By so doing, the operator may rotatably couple the door D to the ceiling C. Such coupling may be reversible, given that in order to de-couple the coupling pin P2 from the coupling element 200 it will be sufficient to act reversibly with respect to the description outlined above.

[0110] Once the operator will have carried the coupling pin P2 in the operative position the operator may lock such position by inserting a suitable split pin 380, that is per se known, thereinto.

[0111] Advantageously, all three operating ends 341, 371 and 351 may protrude from the plane n4 so as to allow an operator to act thereon when the coupling pin P2 is in the inoperative position and when it is in the operative position.

[0112] To this end, the operating end 341, 371 and 351 may be sized to remain interposed between the fixed base element 310 and the ceiling C, so that the operator can access them laterally with respect to the axis Y'.

[0113] In the light of the above, it is clear that the invention attains the pre-established objects.

[0114] In particular, the fastening system 1 with the relative fastening devices 100, 200 and the coupling device 300 will make the operations for fitting and removing the door and alsothe relative adjustments, which may be carried out once the door D has been fitted, extremely simple.
