FR2745323A1 - HINGE FOR DOOR OR PANEL IN PARTICULAR FOR GLASS PANEL - Google Patents

Abstract

The hinge consists of a mobile section (1) attached to the edge of the opening panel (2) and turning about a pivot (4) in relation to a fixed plate (3). The mobile section of the hinge incorporates a spring-loaded roller (12) which engages with notches (13a,b,c) in a block (13) fastened to the fixed hinge plate by a tongue (15) fitted into an adjustable strip (16) at the back of the plate. The engagement of the roller with the notches enables the door to be set stably in opened and closed positions. The roller is made from metal, and the adjustment of the plate allows the effort required to move the door between positions to be varied.

Description

CHOICE FOR LOAN OR PANEL E R GREEN PANEL

  The invention relates to a hinge for a door or panel, in particular for a glass panel, of the type comprising a panel hinge articulated in rotation about an axis on a plate for fixing to a surface.

flat like a wall.

  Hinges of this type are known, the panel hinge of which carries an elastically prestressed locking roller against an indexing block surrounding said axis.

of rotation.

  Document EP 0.599.254 A1 describes a hinge for a glass swing door, comprising on the one hand a fixing plate and on the other hand a hinge hinging about an axis on said fixing plate. Said panel hinge comprises a locking roller mounted on a bushing subjected to the thrust of a prestressed spring, so as to engage elastically in a recess of a substantially cylindrical part coaxial with said axis of rotation. A ball is pressed by a clamping screw with a conical point against said substantially cylindrical part for the purpose of angular adjustment of said substantially cylindrical part and of the door or

  glass panel carried by the panel hinge.

  This known device has several drawbacks: on the one hand, the large diameter of the single prestressing spring applying the locking roller in the recess leads to increasing the thickness of the panel hinge, which is unattractive and expensive; on the other hand, the angular adjustment of the stop position by pressing a ball against the substantially cylindrical part is ineffective and creates unsightly imprints preventing good precision and adjustment

  end of the angular position of the panel relative to the wall.

  The disadvantage resulting from the large diameter of the large single spring leading to an excess thickness of the hinges of the leaves or glass doors is not present in the hinges for shower doors marketed since 1989 under the name MARINE by the company under French law STREMLER, applicant of this request. These hinges for shower doors of known type each indeed have a locking roller mounted on the middle part of a movable axis, the two ends of which are subjected to the thrust of preloaded springs. Thus, it suffices to provide two springs of smaller diameter to obtain an elastic energy equivalent to that of the large single spring provided in the

document EP 599.254 A 1.

  The object of the present invention is to remedy the drawbacks of the known state of the art, by creating a new hinge for a door or panel with a hinge of reduced thickness and an angular adjustment means allowing precise adjustments with good

immobilization efficiency.

  The subject of the invention is a hinge for a door or panel, in particular for a glass panel, of the type comprising a panel hinge articulated in rotation about an axis on a fixing plate; said panel hinge carrying an elastically prestressed blocking roller against an indexing block surrounding said axis of rotation, characterized in that said indexing block comprises a pin movable under the action of a plate adjustable in translation and

  fixed by clamping on a plane.

  According to other characteristics of the invention: Said post is engaged in an integral housing

of the brochure.

  Said plate is disposed on the back of the fixing plate and immobilizable by means of an accessible screw

  from the front of the mounting plate.

  Said plate is contained in a recess of the fixing plate and immobilizable by clamping on the

bottom of the recess.

  Said plate can be immobilized by a clamping means sliding through an elongated opening

in the mounting plate.

  The locking roller is made of resilient material and the

  indexing pad made of metallic material.

  The locking roller is mounted on the middle part of a movable axis whose two ends are subject

  each at the push of two preloaded springs.

  The indexing block has two angular adjustment stops. The two angular adjustment stops are arranged

  on either side of the movable post.

  Each angular adjustment stop is able to come

  resting against the fixing plate.

  The invention will be better understood thanks to the

  description which will follow given by way of example not

  limiting with reference to the accompanying drawings in which: Figure i schematically shows an elevational view with partial section of a hinge according to the invention in the position corresponding to folding

  of a glass panel against the wall.

  Figure 2 schematically shows a sectional view along line II-II of Figure i of a hinge

according to the invention.

  FIG. 3 schematically represents a rear view along arrow III of FIG. 2 of a hinge according to the invention detached from the wall or from the similar fixing surface and in a hinge position

  perpendicular to the mounting plate.

  4 shows a sectional view along line IV-IV of Figure 3 of a hinge according to the invention illustrating the angular adjustment of the hinge. Referring to Figures i and 2, a hinge according to the invention comprises a hinge 1 of panel 2 made of glass articulated to rotate on a plate 3 for fixing about an axis 4 shown diagrammatically by its axis line. The hinge 1 carrying the glass panel 2 comprises a retaining plate 5 secured by two screws 6a, 6b to the body 7 of the hinge 1. The body 7 of the hinge 1 comprises a block 8 in which are formed two housings or bores 9a , 9b able to receive pre-stressed helical springs 10a, lOb. The prestressed springs lOa, lOb push on the two ends of an axis 11 in the middle of which is mounted a locking roller 12. The locking roller 12 is thus elastically prestressed against an indexing block 13 surrounding the axis of rotation 4 and comprising cylindrical recesses 13a, 13b, 13c. In the position shown in solid lines in FIGS. I and 2, the roller 12 made of a resilient material, for example made of polyamide, is engaged in the recess 13a a of the indexing block 13 made of metallic material, for example brass: this position corresponds to a folding of the panel or glass door 2 against the wall M or similar surface on which is fixed the fixing plate 3 by means of screws engaged through the orifices 14a, 14b. Each cylindrical recess 13a to 13c defines a stable position of the panel or glass door 2, either a parallel (13c) or folded (13a) position against the wall, or a hinge position 1 perpendicular (13b) to the fixing plate 3 The passage from one to the other position is done by rotation in the direction of the arrows R around the axis of rotation 4 by application of a torque capable of overcoming the forces.

  exerted by the springs 10a, lob.

  According to the invention, the indexing block 13 comprises a tenon 15 movable under the action of a plate 16 adjustable in translation and immobilizable by tightening a

  screw 17 applying the plate 16 on a plane 18.

  Preferably, the pin 15 is engaged in a housing 19 integral with the plate 16, and the plate 16 is disposed on the back of the fixing plate 3, while the screw 17 is arranged on the front of the fixing plate 3 , so as to be easily accessible for

  perform the angular adjustment of the indexing block 13.

  Advantageously, the plate 16 is contained in a recess 20 formed in the body of the fixing plate 3 and clamped on the bottom 18 of this recess 20 during

tightening the screw 17.

  The screw 17 is preferably slidably mounted along an elongated lumen 21 formed through the fixing plate 3, and a washer 22 is provided under the head of the screw 17, both to distribute the forces of

  tightening and to cover the light 21.

  With reference to FIGS. 3 and 4, in which the identical reference elements designate elements that are identical or functionally equivalent to those of FIGS. I and 2, the hinge according to the invention is shown in the hinge position perpendicular to the fixing plate, corresponding at the position

  shown in dotted lines in Figure 2.

  The implementation of the invention is illustrated in FIG. 4: after having fixed the plate 3 on a wall M or similar surface, the screw 17 is loosened to adjust the glass door or leaf 2 to the desired position, for example perpendicular to the wall, allowing the screw 17 to slide so as to move the plate 16 in the direction of the arrow T. The translational movement of the plate 16 causes the tenon 15 of the block 13 to move

according to an identical translation T.

  Because the pin 15 penetrates with a small clearance in the housing 19 of the plate 16, a translation T of the order of tenths of a millimeter produces a very small and very precise angular displacement of the indexing block 13 around the axis 4. The angular adjustment range is of the order of several degrees and is defined by two stops

  23, 24 arranged on either side of the movable tenon 15.

  In each extreme position, each stop 23 or 24 defined by machining a shoulder on the indexing block 13 comes to bear on the fixing plate 3. In addition, the tightening of the screw 17 applies the plate 16 to the plane 18 from the bottom of the recess 20 and thus ensures by means of a plan-on-plan blocking a firm and reproducible immobilization of the plate 16 and

  consequently of the indexing block 13.

  In addition, due to the fact that the tightening takes place on the plane 18, no imprint is formed in contact with the plate 16 and the plane 18, which makes it possible to refine the adjustment by acting on the end of the panel if that is

desirable.

  This improvement in adjustment was not possible with the ball pressure system of the prior art, because the bowl formed by the impression of the ball no longer allowed fine adjustment in the vicinity of this

footprint.

  The accessibility of the screw 17 sliding in the elongated opening 21 allows easy and rapid adjustment, while the covering of the opening 21 by the washer 22 of diameter greater than the length of the opening 21 gives an aesthetic appearance to the hinge according to the invention and prevents the introduction of impurities or hard bodies into

the guide light 21.

  Advantageously, the pin 15, the plate 16 and the recess 20 are obtained by milling rectangular shapes adjusted respectively to each other to obtain a smooth sliding with a small clearance of the pin 15 in the housing 19 of the plate 16 and the brochure

  16 in the recess 20 of the fixing plate 3.

  The thickness of the plate 16 is preferably less than the depth of the recess 20, so that the plate is completely contained in the recess 20 and does not rub against the wall M when fixing the plate 3 to the wall M. The invention described with reference to a particular embodiment is in no way limited thereto but on the contrary covers any modification of shape and any variant embodiment of the invention, in which the immobilization of the angular adjustment means is obtained by plane-on-plane tightening ensuring immobilization

  reliable and fine adjustment with high precision.
