• Figures 1 - 15 show a first embodiment of a hinge 100 according to the invention, made preferably by extrusion of two parts 1 (see in particular Figure 1 ), with a substantially triangular shape, shaped to obtain the articulations and the connections necessary and substantially equal.
• the hinge 100 according to the invention consists of two parts 1 , which can be mutually coupled (as described in more detail below).
• Each part 1 comprises, in the "vertex" portion of the triangular shape, a vertical seat or groove 2, to receive a panel made of glass or other material (not shown in these drawings) and a plane part 3, opposite said seat 2, which represents the base of the triangle.
• a concave seat or concave vertical seat 4 On the two vertices of the plane part 3 are made a concave seat or concave vertical seat 4, the variable radiuses and centres of which are illustrated in more detail in Figure 5, and a convex seat or convex vertical seat 5, the variable radiuses of which are also shown in more detail in Figure 5.
• the concave seat 4 has larger dimensions than the convex seat 5, and, as will be described in more detail below, their shapes are complementary, so the corresponding convex seat 5 of one of the two parts 1 of the hinge 100 couples in the concave part 4 of the other part 1 of the same hinge 100 according to the invention.
• Figure 5 shows how the cross section of the convex seat 5 has a substantial elliptical shape, with the part with the smaller diameter slightly flattened.
• the convex seat 5 may comprise two semicircles each having the radius R5 and R6 of the same length, for example approximately 8 mm, with the respective centres of rotation C5 and C6 shifted linearly one from the other by a predetermined distance, for example 1 mm, along an axis y' parallel to the longitudinal axis of the seat 2 e and wherein the two semicircles are joined together by two linear sections which form the substantially flattened portion of the elliptical shape of the convex seat 5.
• the hinge is in the neutral position (shown, for example, in Figures 6, 7 or 9) the flattened part may be substantially parallel to the longitudinal axis y of the seat 2, in particular parallel to the direction of insertion of the panel in said seat 2.
• the cross section of the concave seat 4 of each part 1 of the hinge 100 may also have a substantially elliptical shape, in such a way as to house the respective convex seat 5.
• the concave seat 4 has a sufficiently large opening for the for the insertion with slight interference of the narrowest portion, in particular the one with the smallest diameter, of the convex seat 5, in particular at the smaller diameter of the ellipse of the convex seat 5, and to prevent the escape of the larger portion, in particular the one with the larger diameter, of the convex seat 5, in particular at the larger diameter of the ellipse of the convex seat 5.
• the opening is approximately 16 mm.
• the cross section of the concave seat 4 may comprise two circular arcs, each having the radius R1 and R4 of the same length, for example approximately 8.5 mm, with the respective centres of rotation C1 and C4 shifted linearly one from the other by a predetermined distance, for example by 0.5 mm, along an axis z transversal to the longitudinal axis y of the seat 2 and wherein the two arcs are joined together by a third arc, the centre of rotation C3 of which is shifted linearly, transversally to the distance between the centres C1 and C4, with respect to the centre of rotation C1 of the first arc by a predetermined distance, for example approximately 1 mm and the radius R3 of which is less than the other radiuses, for example equal to 7.5 mm.
• the third joining arc preferably represents approximately 1 /10 of the cross section of the concave seat 4.
• This particular geometry allows a fluid rotation between the two parts 1 of the hinge 100 with adequate operational clearance with respect to the same centre of rotation O or O' and a blocking of the coupling during the rotation and the release in the neutral position, when the axis between the two centres of rotation C5 and C6 of the convex seat 4 is substantially parallel to the direction of insertion of the panel in the seat 2.
• the particular geometry of the convex seat 5 is obtained by coupling to it an eccentric bush or ring 16 which has a geometry such as to have a slight interference in the reciprocal concave seat 4 of the complementary part 1 of the hinge 100, when coupled in the neutral position (as shown for example in Figures 6, 7, 9) whilst it has a clearance during the rotation of the same two parts of the hinge 100.
• the geometry of the second embodiment of the hinge 100 according to the invention varies slightly with respect to that of the first embodiment.
• the radiuses R5 and R6 of the two semicircles of the cross section of the convex seat 5 have a slightly different length, in particular, respectively, 7.3 mm and 8 mm.
• the opening of the concave seat 4 is approximately 14.4 mm.
• the centres of rotation C1 and C4 of the two arcs are shifted linearly along the transversal axis z in such a way that they cross each other, so that the centre C4 coincides with the centre of rotation O or O' of the hinge 100.
• the third joining arc has a radius R3 of approximately 8 mm.
• Figures 33 - 38 illustrate the second embodiment of the hinge 100 which preferably comprises two parts 1 as substantially described above, which are in turn divided into two sub-parts 1 a and 1 b, each comprising a concave seat 4 and a convex seat 5 and divided at seat 2.
• the further division of the two parts 1 of the hinge 100 is useful for optimising the production process, simplifying the extrusion of the profiles. Moreover, the further division allows the hinge 100 to be used on panels with different thicknesses, without a dimensional limit, as it is possible to apply the sub-parts 1 a and 1 b at the opposite edges of the panel and then join them with suitable coupling elements.
• the seat 2 may have a groove 18, in particular at the bottom, which allows a possible snap assembly of suitable protrusions 69 of a cover profile 68 (as shown, for example, in Figure 37), preferably with a brush, suitable for reducing the draughts coming from the operational space which is created between the panels and the upper and lower guides.
• Figures 40a - 40d illustrate the rotational movement of the hinge 100 according to the second embodiment with respect to a first centre of rotation O or with respect to the second centre of rotation O' allowing openings in both cases of up to 180° ( Figures 40b and 40d).
• Figures 41 a - 41 c illustrate the detachment movement between the two parts 1 of the hinge 100 of the second embodiment when in the neutral position (of Figure 41 a) and a detachment force F is exerted parallel to the longitudinal axis y of the seat 2.
• the machining operations of the extruded part 1 are rationalised in such a way that the part is cut into equal pieces and subjected to other machining operations of milling, drilling, and galvanic protection treatments which can ensure the maximum smoothness between the various elements.
• Two seats 9, 10 may be formed in the concave cavity 4 for housing springs 1 1 (shown in Figure 4), which are blocked by means of a pin 12 to be inserted in a hole 13, which intercepts the cavity 14 of the spring 1 1 , having a diameter greater than the pin 12.
• Figure 2 illustrates a part 1 of the hinge 100 (that is to say, a half of the 100), provided with all the mechanical machining operations necessary for its operation when coupled with another equal part 1 to constitute the entire hinge 100.
• Figure 6 shows a plan view of the hinge 100 with the plane parts 3 coincident and coplanar; if it is assumed that the part 1 of the left hinge is stationary, applying a force F on the part 1 on the right tending to detach the two parts 1 (Figure 7), the force F overcomes the reaction of the springs 1 1 anchored which open the end arms towards the outside, bot at the top and at the bottom, thus detaching the two parts 1 (see figure 8). In this position, the springs return to the rest condition with the end arms closing inwards.
• the hinge 100 comprises, in this embodiment, four springs 1 1 , so that if the force F acts in a direction normal to the plane parts 3, their detachment is caused by the action of all four springs 1 1 but if the force F acts in a different manner (as shown in Figure 9) there will be a rotational motion which will cause the detachment of two springs 1 1 distant from the axis of rotation O contained in the other two springs 1 1 (see also Figures 9 - 15).
• Figure 9 does not show the springs 1 1 (which could also not be provided, since important, but not necessary) so as to better understand what occurs during the rotations and in particular rotating about the axis of rotation O a part 1 , and keeping still the other part 1 of the hinge 100.
• the convex seat 5 of the first part 1 comes out from the concave seat 4 of the second part 1 , without any impediment, whilst the convex seat 5 of the first part 1 does not come out from the concave seat 4 of the second part 1 because the geometries studied do not allow it (see in particular Figures 1 1 and 12).
• the hinge 100 according to the invention allows, within the maximum permissible degrees of freedom, the rotation about the axis O or about the axis O' allowing in both cases openings up to 180 °. Consequently, it is possible to rotate two panels with each other (not shown in these drawings) so that continuous longitudinal faces can be parallel in both clockwise and anticlockwise rotation. It is immediately evident how, with the hinge 100 according to the invention, it is possible to obtain a greater simplicity and flexibility, since when one orders a product of this type it is no longer necessary to decide which side the panels are to be accumulated, to the right or left, whether they must be opened individually or all together and establish the direction of opening, as all these possibilities are guaranteed by the solution according to the invention.
• the hinge 100 according to the invention may be made of any material, such as, for example, plastic, steel, preferably stainless steel, or aluminium, but it is evident that it can be made with any suitable material, either known or not yet known.
• Said assembly 20, plays a decidedly important role, since, with very reduced dimensions, it allows the panels to be hung using the hinge 100, to carry out fluid rectilinear translational movements of the panels along the upper guides (not shown), being able to roll during the translation; rotational movements on variable angles if the guide are installed joined together with the formation of angles, such as, for example, in the case of closing of areas with two or more sides which are not rectilinear to each other; a rotation up to 360 ° of each single panel with respect to the vertical axis passing through the centres of the assembly 20 and of the pressure assembly (not shown in these drawings), and in any position along the upper guides.
• the hinge 100 is mounted at the top only on one side of each panel or door, in an alternating fashion from door to door, and interacts with the upper guide by means of a pin 22, by which is mounted the reverse rotation carriage assembly 20.
• the upper hinge assembly 100 with reverse rotation carriage assembly comprises the passage of the pin 22 through the part 1 , in particular inserted through the convex cavity 5.
• the pin 22 has two grooves 23 and 24, respectively upper 23 and lower 24. Before insertion in the convex cavity 5, the pin 22 passes through the shaped washer 25, or levelling disc 25, and in the variant illustrated in Figures 17a-17c, perforated centrally.
• a tab 27 (which may also not be provided, since it is important but not necessary) on the shaped washer 25 inserts in the opening 28 of the convex cavity 5 for positioning the washer 25 correctly, also contributing towards an increase in the robustness of the system.
• the pin 22 passes through the part 1 , and comes out at the top inserting into a hole 48 of the plate 21 , keeping it in position by means of a further safety or stop ring 26, in particular of the Seeger type, in the upper groove 23.
• Said plate 21 has a recessed surface 31 which receives, through a hole 32, a pin 33 of the carriage assembly 20, in such a way that the lower groove 34 made on its lower end can also receive a safety or stop ring 35, in particular of the Seeger type, thereby achieving the fixing of the reverse rotation carriage assembly 20 to the plate 21 .
