Definitions

  • the present invention concerns a hinge to articulate a mobile part, such as a door or panel of a door or window frame or a piece of furniture, with respect to a fixed structure.
  • a hinge is known to support door or window frames in which a first hinging element is provided with an axial cavity of a cylindrical shape, into which a cylindrical pin can be axially inserted, and which is provided with a circular throat.
  • a clamping ring elastically deformable, is inserted both into the circular throat of the pin and into an annular seating made in the axial cavity, in order to prevent the pin from coming axially free from the latter.
  • a second hinging element, of the female type is provided with a cylindrical hole, into which the pin is suitable to be inserted.
  • a further disadvantage of the known hinge is that, in order to make the annular seating in the axial cavity, several working steps are needed which are costly in themselves and which therefore increase the overall cost of the hinge.
  • a hinge is known in which a hinging element of the male type comprises a body provided with a cavity conformed so as to have a substantially rectangular cross section and into which a bushing is suitable to be inserted.
  • the lower part, hooked, of a pin having an upper cylindrical part is suitable to be inserted in the bushing.
  • This hinge has the disadvantage that the pin has to be inserted obliquely into the bushing and then aligned with the pivoting axis.
  • Purpose of the present invention is to make a hinge to support the mobile part of a door or window frame or of a piece of furniture, which, as well as preventing the pin from coming axially free from its seating, also prevents the rotation thereof, and at the same time is economical, easy and quick to assemble and guarantees a safe and long-lasting functioning, under any conditions of use.
  • a hinge for a door or window frame or piece of furniture comprises a first hinging element or group, of the male type, having a body provided with a cavity conformed so as to have at least a cross section in which the peripheral points are at different distances from a hinging axis and in which a pin is suitable to be inserted, having at least a first cylindrical part, suitable to be inserted into a corresponding hole of a second hinging element or group, of the female type, and a second part provided with a zone also having a cross section in which the peripheral points are at different distances from the hinging axis.
  • the first hinging element also comprises a bushing, suitable to be interposed between the body and the pin, and which is shaped externally so as to be able to be fitted into the cavity and is provided both with its own axial cavity having a cross section mating with that of the zone of the second part of the pin and into which precisely that zone of the pin is suitable to be inserted, and also with stop means, which are able to cooperate with the pin to prevent the latter from coming free from the bushing.
  • the bushing comprises a central part in which the axial cavity is made.
  • the stop means comprise a plurality of teeth, made at a first end of the central part and suitable to cooperate with a corresponding circular throat made in the second part of the pin.
  • the pin of the first hinging element is perfectly coaxial to the hinging axis and can neither rotate, nor come axially free from the corresponding body which supports it.
  • the circular throat is preferably made between the zone of the pin, coupled with the axial cavity of the bushing, and one end of the second part of the pin.
  • the bushing also comprises a ring made at the opposite end to that where the stop teeth are disposed, and having a diameter bigger than the transverse size of the central part of the bushing, so that it is suitable to function, during use, as a spacer between the body of the first hinging element and the second hinging element.
  • the length of the axial cavity of the latter is greater than its transverse size.
  • the cross sections of the cavity of the body and of the central part of the bushing are both polygonal, for example hexagonal, and such as to allow the bushing to be fitted into the cavity of the body.
  • cross sections of the axial cavity of the central part of the bushing and of the zone of the second part of the pin are also polygonal, for example hexagonal, and have sizes such as to allow the axial insertion, with play, of the second part of the pin into the bushing, while still preventing their reciprocal rotation.
  • a hinge 10 for door or window frames or a piece of furniture comprises a first hinging element 12, of the male type, which in its turn comprises a body 13, made of metal and substantially cylindrical, from which a threaded stem 15 projects perpendicularly, which is suitable to be used to attach, in the known way, the hinging element 12 to a part, for example a fixed part, of a door or window frame, or piece of furniture, not shown in the drawings.
  • a blind cavity 16 is made in the body 13, coaxial to a hinging axis X and having a polygonal cross section, which in this case is hexagonal.
  • Other shapes of non cylindrical cross sections, such as elliptical, oval or irregular, can be used as variants to the polygonal shape, provided that the peripheral points of the cavity 16 are at different distances from the hinging axis X.
  • the hinging element 12 also comprises a bushing 20 ( figs. 1 , 2, 3 and 4 ) made of plastic material, having a cross section mating with that of the cavity 16 and of sizes such as to be fitted in the latter.
  • the bushing 20 comprises a central part 21, of a tubular shape, with a substantially constant thickness, comprised, for example, between 1 mm and 2 mm, so that externally it has the shape of a hexagonal parallelepiped, coherent with the sizes of the cavity 16, and internally has its own axial through cavity 22, also with a hexagonal cross section.
  • six stop teeth 23 are made, that is, one for each face of the central part 21, which are slightly inclined toward the inside of the axial cavity 22. More specifically and by way of example, the width of the axial cavity 22 ( figs. 2 and 4 ) is about 10 mm and its length is about 20 mm.
  • the bushing 20 has a ring 25, the diameter of which is greater than the transverse size of the central part 21 and which is suitable to contact at the lower part the upper surface of the body 13 ( fig. 6 ).
  • a metal pin 30 ( figs. 1 , 5 and 6 ) is suitable to be at least partly inserted, and is shaped so as to have an upper part 31 cylindrical and a lower part 32 of smaller transverse sizes than the diameter of the upper part 31.
  • the lower part 32 comprises a zone 33 with a polygonal shape, mating with that of the axial cavity 22 of the bushing 20, a circular throat 35, suitable to accommodate the stop teeth 23, and a cylindrical end 36.
  • the hinge 10 also comprises a second hinging element 40 ( figs. 1 and 6 ), of the female and known type, which in this case comprises, in its turn, a body 41, made of metal and substantially cylindrical, having a central through hole 42, also cylindrical and, during use, coaxial to the hinging axis X.
  • a plate 43 is attached to the body 42, provided with holes 44 which can be used to attach the second hinging element 40 to a part, for example a mobile part, of the door or window frame or the piece of furniture when the first hinging element 12 is connected to the fixed part of the door or window frame, or the piece of furniture, or vice versa.
  • first hinging element 12 To assemble the first hinging element 12, first of all the hexagonal central part 21 of the bushing 20 is inserted, fitting it from above into the cavity 16, which is also hexagonal, of the body 13, until the ring 25 of the bushing 20 goes into contact with the upper surface of the body 13 ( fig. 6 ).
  • the body 13 is fixed, with the bushing 20 already fitted, to the fixed part of the door or window frame or piece of furniture.
  • the second hinging element 40 is disposed, previously fixed, in a known way, to the mobile part of the door or window frame, above the ring 25 of the bushing 20, so that the hole 42 is coaxial with the axial cavity 22 of the bushing 20 and therefore with the hinging axis X.
  • the pin 30 is inserted from above, first into the hole 42 and then into the axial cavity 22 of the bushing 20, until the stop teeth 23, after being slightly deformed elastically, are disposed elastically and permanently inside the circular throat 35.
  • the pin 30, thanks to the coupling between its hexagonal zone 33, and the corresponding axial cavity 22, which is also hexagonal, cannot rotate with respect to the bushing 20, and therefore not even with respect to the body 13, nor can it come axially free, because of the coupling of the stop teeth 23 of the bushing 20 with the lower edge of the circular throat 35.
  • the upper part 31 of the pin 30 is thus positioned correctly and irremovably with respect to the hole 42 and to the hinging axis X.
  • the ring 25 of the bushing 20 also acts as a spacer between the two bodies 13 and 41 of the two hinging elements 12 and 40, respectively.
  • the hinge 10 can be used without any problem and, in particular, without any possibility that the pin 30 can come free, or rotate with respect to the body 13, in which it is positioned with the interposition of the bushing 20.
