Definitions

  • the invention relates to support devices of the hinge type with lateral mounting for hood or cover pivoting about a horizontal axis close to its rear end, each comprising a spring calibrated so as to balance, whatever its orientation, the weight of the hood cantilevered with respect to this axis.
  • Such hinges with helical torsion spring balancing are generally respectively mounted on opposite side walls, vertically oriented from the skirt of a cover. They each comprise a cup-shaped head with a cylindrical side wall, integral with a fixing lug which can be mounted on the opposite side walls of the housing containing the device to be covered by the pivotable cover.
  • Such an apparatus is, for example, constituted by a disc player with a horizontal turntable which must be made accessible in particular for the installation or removal of the disc carrying a recording, by opening the pivoting cover.
  • the head of a known type of hinge is composed of a cylindrical side wall, closed on one of its sides by a flat bottom in the form of a disc provided with a central opening.
  • This central opening serves to accommodate a cantilevered axis so that it cannot move axially.
  • it includes at one of its ends, a shoulder which is applied against the outer face of the flat bottom.
  • a cylinder is fitted on the axis and made integral with it by gluing, crimping, riveting or overmolding, for example, so that one of its ends is applied against the inner face of this base which is thus clamped on both sides.
  • the other end of the cylinder integral with the axis is integral with a circular disc which is normal to the latter and whose face opposite the bottom of the head is located in the plane of the edge of the wall side of it.
  • an annular cavity is provided between the respective inner faces of the latter, of the bottom and of the disc, and the surface of the cylinder fitted on the axis, making it possible to accommodate a torsion spring of helical shape, for example. That of the ends of the spring which is in the vicinity of the bottom is folded so as to have a radial end which allows its anchoring by insertion into an opening made in the side wall of the head. The other end of the spring is folded back so as to form an axial end which fits into a hole made in the circumference of the disc.
  • the disc is provided on its periphery with four cylindrical projections or pins which are located symmetrically to the pivot axis, two diametrically opposed holes of which are drilled with central holes for anchoring the axial end of the spring and two others of which are provided with holes threaded which allow them to receive the hood fixing screws.
  • the rear part of the cover is pierced with four holes which allow the insertion of these pins whose height is at most equal to the thickness of the cover.
  • the mounting of the hinges on the cover is carried out using a disc-shaped flange whose diameter is substantially equal to that of the cylindrical head and which is pierced by two diametrically opposite holes which allow the passage of two screws respectively. towards the threaded pins, engaged in two of the holes in the cover. The tightening of these screws makes it possible to tighten the rear of each side wall of the cover between the respective opposite faces of the pivoting disc and of the flange.
  • the fixing lug and the head which are integral, their edges, projections and holes are produced in one piece by cutting and stamping a thick metal sheet (1 , 5 - 2mm).
  • the axle with its shoulder and the spring are also made of metal.
  • the integral assembly of the cylinder and the disc as well as the flange are, for example, produced by molding of plastic materials.
  • the mounting of the disc on the axis after the insertion of this one in the central opening of the bottom of the head with the spring already placed, anchored and tensioned in the annular cavity, is a relatively complex operation requiring sophisticated tools and / or automated, so that its production must be carried out in large series to be profitable.
  • two screws are necessary to ensure the mounting of the cover and the flange on the disc. These screws can be tapping and the pins in which they are screwed can be drilled without an internal thread to achieve low savings.
  • the hinge object of the present invention, allows significant savings in labor, during its manufacture, on the one hand, and during its assembly, on the other hand. While performing the same functions as that of the prior art, it is only composed of three parts of which only the spring is metallic, the axis, the disc, the flange and its fixing hub constituting only a single piece of plastic material obtained by molding. Its volume being substantially the same as that of the conventional hinge described above, its weight is notably, less while providing it with satisfactory rigidity and mechanical strength.
  • a pivoting support device or hinge with lateral mounting for hood or cover one of which is mounted on each side of the apparatus or of the housing that the latter is intended to cover, in the vicinity of its rear edge and such that the pivot axis of the cover is parallel to the latter
  • each of the devices or hinges comprising a fixed part, a movable part enclosing between them a side skirt of the cover or cover, provided with holes for the passage of the connecting elements between the different parts
  • the fixed part comprises a hollow cylindrical bearing, of determined length and diameter, the axis of which is normal to the skirt and in that the movable part has a substantially cylindrical central projection passing through the skirt via a hole as well as the bearing, and having at the end enlargements with rounded or sectional ends on its diametrically opposite sides and a slot oriented perpendicular to these enlargements so facilitate their passage through the bearing from which they emerge on the other side by providing a pivoting connection between the movable and fixed parts
  • a flange or circular flat disc 1 constituting the part of the lateral hinge which is mounted outside the skirt. It comprises an appreciably flat outer face 10 and an equally flat inner face 11 and provided with three projections (or pins), normally oriented 12, 13 and 14 and integral, the first 12 of which is located centrally and the other two of which 13 and 14 are respectively arranged on the diametrically opposite sides of the first 12.
  • the first projection 12 or pin substantially in the form of a cylindrical rod, is located in the middle (center) of the internal face 11 of the disc. It is composed of a first cylindrical part 15 of predetermined diameter, followed by a second part 15, which serves as a pivot axis for the flange 1 and which is terminated by a head-shaped enlargement 17 the face of which faces towards the disc is radial.
  • the opposite face of this head forms a tip 18 which narrows, of rounded or sectional shape.
  • the end 18 and the second cylindrical part 16 are separated in two by a diametrical slot 19 over a major part of the height of the latter 16 so as to allow the elastic bending of the two parts thus separated towards one another.
  • This deflection allows, during assembly of the hinge, to penetrate the enlarged end 18 of the second cylindrical part 16 in a hollow bearing whose inner diameter is at most only slightly greater than the outer diameter of the latter.
  • the enlarged end 18 has in the direction of the slot 19, substantially the same dimension as the diameter of the second cylindrical part 16 of the projection 12 or that the internal diameter of the bearing which it must pass right through. , and in the normal sense to this slot 19, a dimension which is at most equal to the sum of this diameter and the width of the latter, and substantially equal to the diameter of the first cylindrical part 15.
  • the second projection 13 (or pin) shown above between the center and the edge of the inner face 11 of the disc 1, is of cylindrical shape and height at most equal to the thickness of the skirt of the cover or cover (not shown ), which is also the case with regard to the first cylindrical part 15 of the first projection 12 whose diameter is at least equal to the largest radial dimension of the enlarged head 17.
  • This second projection 13 cooperates with the first 12 , central when penetrating during assembly of the hinge, respectively into two openings in the side skirt of the cover which have been made therein for this purpose, in order to make this skirt substantially fixed relative to the flange or disc 1.
  • the third projection 14 (or pin) has a section, for example, substantially oval or elliptical (or even rectangular), with its major axis oriented radially and a height significantly greater than the thickness of the side skirt of the cover to emerge from it. interior side. It (14) is provided with a groove or slot 140 in the form of an arc of a circle, the center of which is located on the common geometric axis of the disc 1 and of the central projection 12 and in the middle of this groove 140 with a circular opening 141 parallel to this axis and which passes through it substantially right through.
  • the depth of this groove 140 is preferably chosen to be less than the difference between the height of the projection 14 and the thickness of the skirt, so that its bottom is located slightly towards the outside of the inner face of the latter. ci, when the hinge is fitted.
  • This third projection 14 serves, on the one hand, for anchoring or fixing one end of a torsion spring described below and, on the other hand, as a stop which can determine the limits of the pivoting of the cover.
  • Figures 6 and 7 are respectively a side view of the exterior and a section in elevation (according to CC) seen from the rear, of the fixed part of a left hinge according to the invention.
  • the fixed part 3G of the hinge of FIGS. 6 and 7 comprises an elongated rectangular tab 30, provided with two normal flanges 301, 302 facing outwards, the tabs 30 being held in the base by simple insertion so as to allow disassembly and rapid reassembly of the cover by the user.
  • the depth of the insertion of the tab 30 into this base is limited by a stop 305 which constitutes the bottom of a projecting rib 306 substantially in the shape of a "U".
  • the top of the tab 30 is integral with a cup-shaped head 31 which comprises a cylindrical outer wall 32 closed inwardly of a flat bottom 33 in the form of a washer or ring, carrying in its center a cylindrical cavity 34 extended by a hollow bearing 35, the free end of which is flush with the plane defined by the edge of the wall 32.
  • the transition between the cylindrical bearing 35 and the cavity 34, the diameter of which is considerably greater, consists of a radial surface 36 which , during assembly of the head 31 with the flange 1 allows the engagement of the enlarged head 17-18 of its central projection 12 by snap-fastening (see below and Figure 11).
  • the two central protrusion parts 15 separated by the slot 19 approach each other and penetrate inside the bearing 35 under the effect of a thrust exerted on the flat face 10 of the flange 1, until the widening 17 arrives at the level of the radial bottom 36 of the cavity 34.
  • the two parts separated by the slot 19 move away from each other and the radial face 17 of the enlarged head rests on that of the radial bottom 36 of the cavity 34. Therefore, the head 31 of the part fixed is rotatably joined with the flange 1
  • the common external face 38 of the cavity 34 and of the bearing 35 which is cylindrical, is surrounded by a cylindrical skirt 39 substantially of the same height, one end of which is integral with the flat bottom 33 of the head 31.
  • This skirt 39 is provided with 'A cutout 40 in the form of a niche on a little more than a quarter of its circumference.
  • One 41 of the edges of the cutout is located substantially in the extension of the longitudinal axis of the tab 30, while the other edge 42 is located slightly above a plane normal to this axis and passing through the common axis of the cavity 34 and of the bearing 35.
  • the depth of the slot cutout 40 is slightly greater than the difference between the height of the third projection 14 and the thickness of the side wall of the cover, so that the edges 41 and 42 can act as stops by coming into contact with this projection 14.
  • the space provided between the outer face of the skirt 39 and the inner face of the side wall 32 of the cup or head 31, is intended to receive a balancing coil spring (2G, Figure 4, or 2D, Figure 5).
  • the junction between the side wall 32 and the flat bottom 33 of the cup 31 is interrupted over a part of its circumference between one third and half of it, by a circumferential slot 43 which makes it possible to tension the spring 20 or 21 ( Figures 4 or 5) by its radial end 23 whose end emerges from the head 31.
  • This slot 43 has been shown in a more clear and detailed manner in the sectional views, partially broken away, of Figures 8 and 9. A because of the presence of this slot 43 separating the bottom 33 of the side wall 32, the latter is also joined to the skirt 40 by means of three radial reinforcing ribs 44, on the part not occupied by this slot 43.
  • Figures 8 and 9 are sectional and cutaway views along DD of the respective fixed parts of the left hinges 3G and right 3D, to illustrate the form of slots 43G and 43D.
  • the end of the slots 43G and 43D which is oriented towards the rear of the housing or frame (not shown) to be covered with the pivoting cover, is provided with an axial extension or parallel to the generator 45 which is located in the vicinity of the junction of the rear edge of the tab 30 with the wall 32 of the cup and which is intended to accommodate the radial fold (23) of the spring (20 or 21), during assembly.
  • the other end of the slot 43 which faces forward, is provided with an angled extension composed of a radial part 46 and a short circumferential part 47 which is parallel to the slot 43 itself, so as to form a sort of inverted "L".
  • the end of its radial fold 23 is retained by the bottom of the circumferential part 47 on which it then rests.
  • the height of the radial reinforcing ribs 44 is chosen to be substantially equal to that of the inner edge of the circumferential part 47 housing the radial fold of the spring (20 or 21) whose inner turn is supported there.
  • Figure 10 shows a partial section in elevation of the hinge assembled with the side wall of the cover in horizontal position (closed) and Figure 11 shows a section along ⁇ of Figure 10 (which is a section along FF of Figure 11 ).
  • the flange 1 has not been cut and one sees there only its flat disc-shaped part with its central projection 12, the first cylindrical part 15 of which passes through a hole 51 in the side wall 50 of the cover. 5 and whose second cylindrical part 16 constitutes the pivot axis which can rotate in the bearing 35 of the fixed part or head 31. It can also be seen there that the head or the enlarged end 17-18 of the central part 16 ensures the assembly of the flange 1 with the head 31 of the fixed part, by its engagement with the flat (radial) bottom of the central cavity 34.
  • FIG. 11 it can be seen that the two diametrically opposite pins or studs 13 and 14 of the flange 1 engage respectively in holes 52 and 53 crossing the side wall 50 of the cover 5, so as to anchor that this compared to that one.
  • a hinge produced in accordance with the invention comprises a minimum of components (three), is easy to produce, as well as to assemble. Consequently, it constitutes a significant saving compared to those of the state of the art.
  • Another advantage is constituted by the fact that during assembly of the hinge, the spring is not tensioned and does not require complicated tools to join the fixed part to the rotating part.
