Abstract

The hinge comprises a split hinge (1) articulated to rotate on a fixing plate (3) around a spindle (2). The split hinge comprises a bloc in which there are two housings receiving pre-stressed springs (7a). Each spring applies an indexing means (8a) against an indexing socket coaxial with the articulation spindle.

Description

The invention relates to a hinge of the type comprising a hinge

  articulated in rotation on a fixing plate around an axis.

  This type of hinge is generally used to pivot a gate or a panel, in particular a glass panel relative to a generally vertical plane surface such as a wall.

  Document EP 0 867 586 B1 describes a hinge, of the type comprising a hinge articulated in rotation about an axis on a fixing plate. The hinge comprises a block in which are formed two housings intended to receive elastic prestressing elements. The hinge is indexable in position by cooperation of an indexing roller elastically prestressed against a recess of an indexing conformation surrounding said axis of rotation. The elastic elements exert a thrust at each end of an axis on which said indexing roller is mounted. A centering separating element is mounted between each end of the support axis of the indexing roller and each elastic prestressing element.

  The hinge of document EP 0 867 586 B1 is generally satisfactory, but requires the manufacture of numerous parts and the performance of several precision machining operations, as well as the production of an additional system for adjusting the perpendicularity of the wicket or glass panel by relative to the wall or similar flat surface.

  A first object of the invention is to simplify the production and manufacture of the hinges for a gate or pivoting panel, by reducing the number of parts required.

  A second object of the invention is to simplify the hinge adjustment system, in order to facilitate the adjustment of the perpendicularity of the door or glass panel with respect to the wall or similar flat surface.

  The invention relates to a hinge, of the type comprising a hinge articulated in rotation on a fixing plate about an axis; said hinge comprising a block in which are housed two housings intended to receive elastic prestressing elements, characterized in that each elastic prestressing element directly applies an indexing means against an indexing bushing coaxial to said articulation axis .

  According to other alternative characteristics of the invention - the fixing plate comprises a clamping means for securing the hinge pin to each indexing sleeve and to the fixing plate, the fixing plate has a slit part intended to be clamped to radially compress a part of the indexing sleeve against the articulation axis, - each indexing sleeve comprises at least one recess intended to cooperate with an indexing means, - each indexing means has a mushroom conformation with a rod inserted into an elastic prestressing element and a head applied against a part of the indexing bush, - the articulation axis is mounted by means of bearings in the hinge, - each element is a helical spring compression compression device prestressed 15 in a bore of the hinge, - the clamping means comprises a clamping screw intended to tighten a slot in said split part of said pla fixing tine, - each recess provided in an indexing sleeve is a cylindrical recess, - each head of the indexing means is at least partially cylindrical.

  The invention will be better understood from the description which follows given by way of nonlimiting example with reference to the accompanying drawings in which: - Figure 1 shows schematically, an elevational view with partial section of a hinge according to invention.

  - Figure 2 shows schematically a sectional view through the plane IIII of Figure 1 of a hinge according to the invention.

  With reference to FIGS. 1 and 2, the identical or functionally equivalent elements are identified by the identical reference numbers.

  In FIG. 1, a hinge according to the invention comprises a hinge 1 of a door or glass panel, articulated in rotation about an axis 2 on a plate 3 for fixing to a flat surface such as a wall.

  The hinge 1 intended to carry the door or glass panel comprises a body 4 and a retaining plate 5 fixed to the body 4 by two screws, not shown, intended to be screwed into the bores 6a, 6b of the body 4.

  The body 4 has a block in which are formed two housings intended to receive helical springs 7a, 7b of compression which are mounted prestressed.

  The pre-stressed springs 7a, 7b push the mushroom-shaped elements 8a, 8b against indexing sockets 9a, 9b coaxial with the axis 2 of articulation.

  Each mushroom-shaped element 8a or 8b has a rod inserted into a helical spring 7a or 7b and a head in the form of a half-cylinder intended to cooperate with one or more cylindrical recesses of a socket 9a or 9b, so as to maintain an angular position between the hinge 1 and the plate 3 in the form of a square.

  The hinge 1 is mounted for rotation about the hinge axis 2, preferably with the interposition of bearings 1 Oa, 1 Ob.

  The plate 3 in the form of a square has a first part 11 intended to be fixed to a wall or similar surface not shown and a second part 12 perpendicular to the first part 1 1 and allowing coaxial mounting of the sockets 9a, 9b and the axis 2 of articulation with possible interposition of the bearings 10a, lOb.

  The second part 12 is split laterally and carries a tightening screw 13 allowing the coaxial tightening of the sockets 9a, 9b and the hinge pin 2, as well as their attachment to the part 12 of the plate 3.

  Preferably, each indexing sleeve 9a or 9b is made of a non-metallic material having good mechanical strength.

  To use the hinge according to the invention, the plate 3 is first mounted against a wall or a flat surface and then a glass panel or door is mounted on one or more hinges 1.

  By slightly loosening the screw or screws 13, it is then possible to adjust the perpendicularity of the panel or glass door relative to the wall or similar flat surface.

  Then tightening the screw (s) 13, the perpendicularity adjustment 5 thus produced is fixed by securing the indexing sockets 9a to the hinge pin 2 thanks to the compression exerted by the closing of the slot, closure obtained by tightening of screw 13.

  In the example shown, the ends of the indexing sockets 9a, 9b which are wedged in the part 12 of the fixing plate 3 have a diameter 10 less than the outside diameter of the indexing part proper: the invention s also extends to any other embodiment of indexing sockets, the main thing being that their ends are wedged in part 12 of the fixing plate 3 after adjusting the perpendicularity of the panel or gate relative to the wall or flat surface similar.

  The invention described with reference to a particular embodiment is in no way limited thereto, but on the contrary covers any modification of form and any variant of embodiment within the scope and spirit of the invention, the main thing being that the indexing means are coaxial with the hinge axis, without requiring the manufacture or use of additional parts.
