Definitions

  • the invention relates to a hinge assembly for the opening of (capsizing) drop-leaf doors, preferably with all the hinge body embedded in the furniture.
  • Some connecting-rod hinges reduce the air gap to 2.5 mm, but must be discarded for capsizing leafs because at the end of the opening movement the leaf is flush with the plane of the furniture and the connecting-rods come out from the plane. For example, for a leaf door that acts as a desk when opened, the protruding connecting-rods are unsightly and an obstacle to the writer.
  • FIG. 1-3 Another commercially known type of hinge for furniture is shown in Figures 1-3 . It consists of three pieces: a box 14 to be inserted inside a fixed plane 12; a box 34 to be inserted inside a leaf 32 and a connecting pin 36 mounted in the first two. By 46 are indicated in dashed line the edges of the necessary holes in the wood.
  • the pin 36 is fixed in the box 14 by a screw, and comprises two pins 42, 44 sliding in guide grooves 40, 38 present in the box 34.
  • the set of pins 42, 44 and grooves 40, 38 form an articulated quadrilateral, which allows the leaf 32 to rotate by 90 ° and come flush with the plane 12 when it is opened.
  • Figure 3 shows in dashed lines the trajectories 48 of the outer edge of the leaf 32 in dependence of its thickness. E.g. to a thickness of 22 mm corresponds an air gap of 6.5 mm.
  • the invention proposes to solve this problem with a hinge that reduces the air gap between the leafs.
  • the solution is a hinge as defined in claim 1.
  • the technical effect of the hinge is a vertical offset of the leaf, which allows to recover in height part of the thickness of the leaf.
  • the hinge according to the invention is able to lift the leaf in the horizontal position with respect to the supporting surface of the shelf or base.
  • the leaf's thickness recovered in height results in an equal reduction in the capillary gap. Note that the work-top of the open leaf is not invaded, because there are no parts of the hinge in relief, and the vertical offset is irrelevant to the user.
  • the fixed and movable member can have any shape (spherical, prismatic, etc.), and various structures, being sufficient that it acts as anchoring to the base.
  • the fixed member is embeddable in a blind hole of the shelf and/or has a part or upper side (e.g. flat or almost) which is flush with the shelf.
  • the movable member it is preferred that one or both have a flat or almost flat side to be placed flush with the respective base or leaf. In this case, when the hinge is opened (that is, when the leaf is horizontal and in the end position) the flat or almost flat side of the movable member lies in a plane parallel and offset with respect to that on which lies the flat or almost flat side of the fixed member.
  • the pins can be made either on the arm or on the movable member, and, correspondingly, the guiding grooves are on the movable member or the arm.
  • the grooves can have various lengths and shapes: both straight, one straight and one curved, both curved. Straight ones are preferred for simplicity of construction, but more complex shapes allow more efficient leaf movements and air gaps.
  • An embodiment which proved simple, reliable and without jamming is defined in claim 3.
  • the hinge can obtain said offset in height by varying one or more of its constructive parameters (e.g. shape, position and length of the grooves, shape of the arm, form of the fixed or movable element, spacing of the pins) it is preferred for simplicity to act on the position of the pins, by placing them as defined in claim 4. Another possibility is referred to in claim 5.
  • the shape of the arm is, as mentioned, the shape of the arm.
  • it is produced as defined in claim 6.
  • the straight segment can be blocked or even integral in one-piece to the fixed element.
  • the movable member can comprise the elements defined in claim 7. So the arm can be inserted therein and be moved by embedding the movable member into the leaf.
  • the movable member preferably has only one edge, opposite to the open side, which extends to form a lip, e.g. drilled for a fixing screw.
  • the fixed member preferably comprises the elements defined in claim 8. Thus the joint takes place on an edge, and is easy to do.
  • the fixed member can have a flange which extends around the open side perpendicular to the upper part (e.g. flat) and preferably has through-holes for a screw.
  • the flange - or in general a portion of the fixed member - can comprise a recess as defined in claim 8.
  • the profile of the shelf "seen" by the leaf is carved or recessed, thereby increasing the movement trajectories of the leaf. This is very important in the search for movements to move the leaf between the two open/closed end-positions inside increasingly small spaces (the air gap between the leafs which one wants to minimize).
  • the invention also proposes a mounting and/or guiding method of a leaf, as in Claim 10.
  • the structure of a hinge as in figures 1-3 is used, modifying it so as to obtain said already described vertical offset for the leaf in the end position.
  • a hinge 50 is formed by three components: a fixed member 80, a movable element 60 and a separable connecting arm 52. In the drawings they are shown with the orientation that they assume during use.
  • the fixed member 80 is to be inserted into a blind hole of a shelf or base 98, and comprises a body 82 in the form of a small basin or box.
  • the body 82 has the upper part 84 which is flat, and an opening 86 on one side adapted to receive one end of the arm 52. From the open side a fixing flange 88, which has through holes 89 for a screw, extends perpendicularly to the upper part 84.
  • the flange 88 comprises two recesses 87 at the sides of the opening 86.
  • the upper part 84 is to be mounted flush with the shelf 98, while the flange 88 is arranged on its edge.
  • the movable member 60 which in turn is embeddable in a blind hole made in the edge of a leaf 96, comprises a body 62 shaped like a small basin or box with a flat upper surface 61.
  • the body 62 has an open cavity 66 which renders it open on two adjacent sides, while on the opposite side it has an edge which extends to form a fastening lip 68, in which a hole 56 for a screw is present.
  • the flat surface 61 is disposed flush with the plane of the leaf 96, and the lip 68 is screwed at it.
  • the side walls of the cavity 66 each comprise two rectilinear guiding grooves 58a, 58b.
  • the grooves 58a, 58b have a respective axis M1, M2 (see Figure 4 and 7 ) inclined with respect to the plane passing through the surface 61, respectively of about 45° and 3°.
  • the arm 52 comprises a forked end 54, destined to be made integral to the fixed member 80 via a screw, an intermediate rectilinear segment 70 and another end 66 comprising a head 69 e.g. having a cubic shape.
  • the head 69 is used to have an upwards development orthogonal to the segment 70 and to carry in integral manner (e.g. in one-piece) four pins 72, two on one side and two on the opposite side.
  • the pins 72 have a horizontal axis and are two by two coaxial.
  • the arm 52 has a symmetrical structure along a vertical median plane.
  • the head 69 With the assembled hinge the head 69 is arranged in an oscillating manner and with little play in the cavity 66, so that the pins 72 are inserted and can slide in the respective grooves 58a, 58b (see e.g. Fig. 5 showing the hinge 50 in the open configuration).
  • the elastic deformation of the cavity 66 is enough for the insertion of the pins 72, or they may be separate elements and inserted when needed in holes of the head 69.
  • the pins 72 have axes aligned vertically with each other, and the two upper pins, coaxial, are at a height ⁇ greater than the lying plane of the upper part 84, and therefore also than the flat surface of the shelf 98.
  • the pins 72 move inside the guides 58a, 58b, whose geometry ensures for the leaf 96 a movement outgoing from the furniture inside the micro air gap without impacts with other leafs 99 (in dashed lines in fig. 8 ).
  • the innermost edge of the movable member 60 could get stuck on the flange 88.
  • the presence of the recess 87 totally optional, eliminates this drawback, allowing the transit of the edge and the adoption of more complex trajectories for the leaf 96.
  • the leaf 96 becomes parallel to the shelf 98.
  • the leaf 96 is also offset in height with respect to the shelf 98.
  • the offset is indicated by ⁇ , and is, for example. 8 mm
