Definitions

  • the present invention relates to a folding door consisting of at least two panels hinged one on the other, allowing to release a wide opening, while occupying in the open position a reduced clearance.
  • Figures 1 and 2 show in schematic horizontal section the operation of such a door. It consists of two panels, a first panel 1 and a second panel 2 joined by a hinge 3.
  • the first panel 1 whose width in this example is half that of the second panel 2, that is to say the third of the width of the door, and articulated on the upright or frame 4 inscribed in an opening in the partition 5.
  • the second panel is articulated on the first.
  • the second panel 2 folds back against the first panel 1. This has two advantages.
  • the door scans a reduced surface 6, and once opened, the door projects beyond the partition only by a third of its width, on either side of the plane of the partition.
  • French patent 2,447,445 describes such a door adapted to open in both directions, and mounted in a special frame. Articulation systems are complicated and expensive. The presence of such a door with its frame must be provided when drawing up the construction plans. The installation of such a door in an existing building involves the change of the framework, therefore important masonry work.
  • Folding doors for cupboards are also known, of simple structure, for example by French patent 2,057,490.
  • This folding door has a limited clearance and can be installed in a relatively simple frame on which slides can be adapted to the upper part and on the ground, the articulations of the panels being able to move in these slides.
  • the main object of the present invention is to propose a door having these advantages, at a price comparable to that of an ordinary door.
  • the invention mainly provides such a folding door with reduced clearance, using a standard frame.
  • the invention relates to a folding door assembly of the type comprising two panels hinged to each other, a first panel of small width articulated on an upright of the door frame and a second panel of greater width articulated on the first, this second panel in the open position of the door coming to be placed across the frame, with a part on each side thereof, characterized in that the door is used in combination with a conventional rebate frame without element on the ground, and that the articulation of the first panel is fixedly located at a distance from the upright sufficient to allow the opening of said first panel in the opposite direction to the rebate, so that in the position of closing the edge of the second panel comes beat in the rebate, allowing the use of a conventional lock, and in that it further comprises a profile formed with a groove, this profile being intended to be be placed in the rebate of the lintel, so as to allow sliding in the groove of a finger secured to the second panel.
  • the second or large panel opens by a usual gesture like an ordinary door, with a handle near the edge and a standard lock and not like a cupboard door grabbed by the center.
  • the coming of the edge of the panel in the rebate allows a high quality shutter, allowing the use of the door as a fire door for example.
  • the second panel has a width equal to twice that of the first. There is thus obtained, with two panels, a clearance reduced to the maximum, the door in the open position advancing on each side of the frame only one third of its width.
  • Figure 3 is a sectional view of a standard metal profile 10 for a standard interior door frame of living quarters. It comprises a rebate delimited by the wings 11 and 12 of the profile.
  • the width of the wing 12 defines the thickness of the door that can be adapted within this framework.
  • the width of the wing 11 defines the extent of the overlap between the door and the frame under standard conditions.
  • a profile 15 is used ( Figure 4) forming a guide rail, and whose dimensions correspond substantially to those of the rabbet.
  • a length of the section 15 is placed corresponding substantially to the opening of the opening.
  • the lower surface of the lintel ( Figure 6) once filled with this profile is then substantially flat and defines the upper level of the door, which can then pass below and debate on one side or the other.
  • the profile 15 can be welded or screwed to the lintel, or otherwise fixed.
  • the first panel 1, the width of which is substantially equal to one third of the width of the door is articulated on the frame by two pivots.
  • a first upper pivot comprises a finger 20 (FIG. 7) which can be engaged in the hole 21 of a plate 22 advantageously fixed in the profile 15 (FIG. 6).
  • the finger 20 can slide in a tube 23 housed in the thickness of the door and be urged upward by a spring 24.
  • To remove the door simply lower the finger 20 for example to by means of a cleat 25 passing through a slit of the tube 23 and a slit made in the door, and flush with the surface of the edge thereof.
  • a second lower pivot may be constituted by a boss 30 formed on a stamped sheet 31, fixed to a bracket 32, itself fixed to the upright 4 of the frame.
  • An arm of the square is passed inside the frame by an appropriate cutout.
  • the fixing can be carried out by screws, welding or otherwise.
  • Figure 11 shows in section the female counterpart 35 of the male pivot 30. It can be a plastic cap, housed in a correspondingly shaped cavity formed in the bottom of the door.
  • the friction between plastic and metal is noise-free, wear-free and lubricant-free.
  • Such a cradle easily withstands high loads much higher than those that can support hinges.
  • the panel 1 thus mounted, will support the second panel 2 without drawbacks by suitable hinges.
  • pivot axis is therefore located substantially in the median plane of the frame rebate, and at a distance from the inner edge thereof equal to half the thickness of the door, in the most reasonable case, or the pivot axis is placed at equal distance from the two faces.
  • FIG. 8 represents a guide finger of the second panel 2 articulated on the first.
  • the finger has an axis 41 on which a roller 42, for example made of plastic, is rotatably mounted.
  • the roller 42 rotates freely inside the profile 15, with a minimum of play.
  • the axis 41 can simply be screwed into the top of the panel 2, in the middle of the width. This roller is simply used to guide the door. It is not a carrier, it does not support the panel 2. This is supported by the panel 1, by appropriate hinges 51, 52, 53.
  • Figure 12 shows schematically the door in place in its frame.
  • the panel 1 is articulated by the lower pivot constituted by the cap 35 resting on the boss 30, and by the upper pivot constituted by the finger 20 engaged in the hole 21 of the plate 22, fixed to the profile 15 itself fixed to the profile forming the lintel 16.
  • the second panel 2 is articulated on the first, for example by three hinges 51, 52, 53, of the type allowing one panel to be completely folded against the other.
  • the panel 2 is further guided by the roller 42 sliding in the profile 15.
  • a lock 55 keeps the door in the closed position. Note that it is a usual lock, of the type normally used on conventional doors with a single leaf. It opens, with the door, by a usual gesture, as for a traditional door, and not as a cupboard door, foldable in V, which is gripped by the middle.
  • the invention applies equally well to any frame rebate of any type, made of metal or wood.
  • the invention makes it possible to replace any existing door with a folding door, with a minimum of expense.
  • the profile 15 will be made of metal, although a wooden profile (a rod) with a groove and a hole 21 can work very well.
  • the folding door according to the invention is advantageously mounted with two pivots, preferably with conventional hinges, the pivots being at a sufficient distance to allow the opening of the first panel in the direction opposite to the rebate, and with the addition of the upper section 15, with the roller 42 corresponding to the middle of the second panel 2.
  • Figures 13 and 14 show in horizontal section a door according to the invention in the closed state, and in the half-open state, respectively.
  • the hinge 61 connecting the panel 1 to the upright 4 is not placed in the usual place, but is moved away from the edge of the panel 1 to allow its opening in the opposite direction of the rebate.
  • the outer edge 56 of the wide panel 2 flaps (arrow F) in the rebate 57 of the upright 4 ' in conditions similar to those of a computer door nary.
  • the door according to the invention is normally equipped with a standard lock 55, absolutely normal, and ensuring the closing and blocking of the door as for an ordinary door.
  • the initial movement of the edge 56 of the panel 2, during opening is perpendicular to the plane of the frame 4, with only a shorter radius of rotation.
  • the opening is done by a usual gesture.
  • a door according to the invention can be replaced in place of a conventional door at any time, when designing a housing, when it is put into service, or afterwards. The designer architect does not have to reserve the sites which will be fitted with such doors. It is also possible, with two folding doors, to close a wide opening, that is to say the equivalent of a retractable partition.
