Description

Furniture hinge system and its method of implementation

  The invention relates to a hinge system

  for furniture and its method of implementation.

  Furniture is understood to mean furniture that is easily moveable and deformable, such as, for example, removable partitions, such as a screen, consisting of panels hinged together on one another by means of vertical hinge pins, and called

usually small screens.

  It is known to produce such partitions consisting of rigid panels vertically lined with metal profiles provided with a vertical groove dovetail in which is inserted a male member carried by a hinge member mounted on a central axis sliding vertical connecting between

  they-the different parts of articulation.

  This type of articulation poses some problems at the level of its placement. First, the central axis is the same height as the partition board. To put it in place, it is necessary either to have a ceiling height double the height of the panels, or to present the panels in an inclined position in order to set up the central axis. Then, it is necessary to provide stop means so that the hinge parts do not slide longitudinally by

  report & the axis that leans on the ground.

  One of the aims of the invention is to provide a hinge device which eliminates the

  concept of central axis while ensuring the same function.

  Another object of the invention is to propose a method for implementing the septum articulation system which only uses

simple operations.

  The invention relates to a furniture hinge system whose panels are vertically bordered by metal profiles provided with a vertical groove with a narrow opening relative to its maximum width, of the type in which hollow cylindrical hinge parts, reduced in height relative to the height of the panel, each carry a male element capable of sliding in said groove, characterized in that the mechanical connection pivoting between adjacent articulation parts each connected to a panel is provided by sockets substantially cylindrical, having a projecting central ring and two cylindrical skirts symmetrical with respect to the median ring, fitting into said adjacent articulation pieces, the middle ring constituting sliding bearing between said pieces

adjacent articulation.

  The subject of the invention is also a process for implementing the above-mentioned jointing system for furniture, characterized by the following steps: - a first piece of articulation occupying the first piece of articulation is placed on a first metal profile bordering a first furniture panel; lowest position

on the profile, -

  on a second metal profile, bordering a second furniture panel to be articulated on the first, a second articulation piece occupying on the profile a position starting from the bottom offset from the height of an articulation piece increased by the thickness of a median ring; in the first articulation part, a first sleeve is inserted whose lower cylindrical skirt slides in the articulation piece and whose middle ring rests on the articulation piece; placing said second articulation piece on said first bushing whose upper skirt penetrates into the second articulation piece; a second socket is placed in said second articulation piece; placing a third articulation piece with its male element in the groove of said first section and let it slide until it covers said second sleeve; - we put up a third socket; placing a fourth articulation piece with its element mAle in the groove of said second section, and let it slide until it covers the third sleeve; a fourth socket is put in place; - and so on Until we arrive

at the top of said panels.

  Other features emerge from the

  following description made with reference to the drawing

  attached to which can be seen: Figure 1 a cross-sectional view of a metal section bordering vertically a furniture panel, Figure 2 a cross-sectional view of a hinge part according to the invention, Figure 3 a view of above showing the arrangement of the hinge parts and profiles between two furniture panels according to the invention, Figure 4 an exploded view of the hinge system according to the invention between two furniture panels. Referring to Figure 1, we see that the metal section 1 has two side wings 2 and 3 between which is inserted the vertical edge of a furniture panel (not shown). This panel comes into abutment on the two cross members 4 and 5. On its opposite part to the panel, the profile 1 has a vertical groove 6 whose opening is limited by two lips 7 and 8 with cylindrical outer surface. This opening is narrow relative to the maximum width of the groove, so that the male element 10 of the hinge part 11 shown in FIG. 2 can slide longitudinally in the groove 6 without

  can be extracted transversely.

  In FIG. 2, the articulation piece 11 is cylindrical, and its height is much smaller than that of the profile 1. In the zone 12 which carries the male element 10, the thickness of the articulation piece 11 is reinforced. . This area is limited by the lips 7, 8 of the profile on which it is based. This reinforced thickness is intended to avoid scratching the lateral surface of the articulation parts during the movements of the furniture panels: in fact, the profile of one of the panels can not rub on the linked articulation parts to the other adjacent panel. The zone 12 extends over the entire height of the articulation piece 11. The male element 10 consists of two bent walls extending over the entire height of the articulation piece, so that the flanged wings bent walls slip

  behind the lips 7, 8 of the profile 1.

  FIG. 3 shows two profiles 1 and 1a, a hinge part 11 with its male element 10 placed in the groove 6 of the profile 1, and the male element a, of the lower hinge piece masked by the articulation piece 11, placed in the groove 6a of the profile la. Due. of the cylindrical shape of the lips 7 and 8 of the profile and the corresponding shape of the articulation part, there is no possibility

  direct view through the articulation system.

  This means that there is visual and sound insulation at the joint of the panels, and that the joint is an obstacle to drafts. In Figure 4, we see the two sections 1 and la, with hinge parts 11, 11a, 11b, intended to be alternately connected to the profiles 1 and 1a, respectively. To ensure the mechanical link pivoting between the hinge parts 11 and 11a, for example, connected to two different panels, sockets such as 12 are used. A bushing 12 is substantially cylindrical, it includes a central ring 13 projecting towards the outside, and skirts symmetrical with respect to the ring, a lower skirt 14 and an upper skirt 15. The lower skirt 14 is intended to penetrate into the upper part of the articulation piece 11, to rotate frictionally therein soft. For this purpose, the skirt advantageously has small ribs 16 which are found in the same way on the upper skirt 15. The middle ring 13 is supported on the upper edge of the articulation piece 11, and supports the lower edge of the hinge piece 11a. The upper skirt 15 is then placed in the lower part 1o of the. articulation piece 11a, in which it pivots with gentle friction. The sleeve 12 thus provides a mechanical connection pivotally between

  the two hinge parts 11 and 11a.

  The implementation of the hinge system for furniture panels according to the invention comprises the following steps: first, the male element 10 of the hinge part 11 is slid into the groove 6 of the profile 1. The hinge piece is placed so that its lower edge is flush with the lower edge of the profile 1. From the inside of the profile 1, and through the bottom of the groove 6, the hinge piece 11 is fixed to the profile 1, by screwing by

example,

  - Then we fix the profile 1 on its panel, for example by screwing from the outside and through the bottom of the groove 6, - we proceed in the same way with the profile and the hinge part lia that l it is fixed in the 0 position that it will occupy in the articulation device, that is to say at a distance from the lower edge of the profile equal to the height of the hinge part 1 increased by the thickness of the middle ring 13 of the sleeve 12, - the profile is fixed on the corresponding panel; two panels each vertically bordered by a section which carries, rigidly fixed, a hinge part in its lower part, are then arranged; in order to support the articulation device and the two corresponding panels, it is possible to constitute a foot using a nozzle 17, made from a sleeve 12 without a lower skirt, on which is placed a hollow cylinder 18 corresponding to a hinge piece without male element, then a sleeve 19 for receiving the hinge piece 11 connected to the profile 1, - is then placed in the hinge part 11 a sleeve 12 and over this sleeve the hinge piece lla attached to the profile 1a; the two sections, integral with their respective panel are then substantially in their final relative position, - is then placed in the hinge part 11a a bushing 20, - is then inserted into the profile 1 the male element of a piece d 11b, from the top of the profile 1, and let it slide until it covers the upper skirt of the sleeve 20, - then a socket is put in place, then a sliding articulation piece in the profile la, 'and so on, alternately, until the last hinge piece is flush with the upper edge of the profiles; we can then finish by setting up a mouthpiece, such as 17, including the Skirt

  lower part fits into the articulation piece.

  Thus, according to the invention, instead of producing a hinge axis by a metal rod of height equal to that of the panel, and therefore difficult to implement, a series of symmetrical bushings is used which provide the mechanical connection to pivoting. hinge parts two by two. Therefore, it is sufficient to have, above the panel, a height equal to

that of a piece of articulation.

  According to an alternative embodiment, it is possible for the foot to support the profiles 1 and 1a. It suffices to use a bushing 19 with a protruding median ring whose outer diameter is large enough for the ring to act as a stop for supporting the metal sections. Under these conditions, it is unnecessary to fix the hinge parts 11 and 11a on their respective panel, which simplifies the operations of implementation of the hinge system.
