Definitions

  • This invention relates a closing and/or opening device for a moving part of a piece of furniture. More particularly, it relates to a drawer equipped with a latch-type device and elastic means to facilitate opening.
  • latch-type devices or latches are used to open or close or at least facilitate - depending on the function for which they were designed - moving doors or drawers of pieces of furniture. These latches generate a slight contrasting force during closing; this force is stored by the elastic parts and is released later on during the inverse operation, opening.
  • the drawer When using a latch to facilitate the opening of or to open a drawer, the drawer is kept in its closed position by appropriate devices, which can be separate from or integral with the latch for example, hooking devices, magnets, etc..
  • the latches of the type described above are fastened directly on parts of the piece of furniture housing the drawer and on the drawer itself, unforturnately, their placement is subject to sizing or positioning imprecision that may cause the drawer to jam or close imperfectly.
  • the mechanism of a latch does not work property, it may be difficult to grip the drawer to open it because the drawer is not fitted with handles and/or because the drawer did not open enough to facilitate opening.
  • the device of the invention can be fitted quickly, precisely, and easily.
  • the device is fitted without the use of special tools and is securely fastened, guaranteeing against breakage or detachment from the drawer guide to which it is fastened. Given the precision of the resulting coupling, the proper working order of the latch is ensured.
  • the latch also comprises elastic means able to carry out an opening stroke adequate to enable the drawer to be opened easily or to do away with this manual action completely.
  • This drawer guide device comprises a latch 1 secured to a plate 2, which is fastened to a guide 3 of a drawer 13.
  • the second guide is not shown; this is generally present in drawers and, together with the first, forms the guide system.
  • the latch 1 is fastened to the fixed guide 3 but can also be suitably fastened to a moving guide 5, while remaining within the scope of this invention.
  • a retainer 4 is also included; this is integral with the moving guide 5 and protrudes from its side wall with two ribs, which are essentially in the shape of a "C". In this way, said retainer can be appropriately fastened both to the left guide and to the right guide.
  • the latch 1 is integral with a plate 2; it can be fastened, for example, with a bent element 11 or, alternatively, it can be welded or attached using appropriate means.
  • Two tabs 12 are provided in the plate 2, for example, through die forming. These tabs are raised compared to the plate and, due to the material and the way in which they are made, are able to exert an elastic gripping force against the surface of the fixed guide 3.
  • the fixed part 3 of the drawer guide device G comprises two holes, with an essentially elongated shape or in the shape of slots, which can house the tabs 12. A sliding movement locks the tabs 12 inside the corresponding slots of the plate 2; this mechanism makes the plate 2 integral with the fixed guide 3.
  • the latch in teracts with a retainer, which is integral with the other guide, in this case the moving guide 5.
  • the retainer 4 can be machined directly in the material of the guide 5 or can be welded or screwed into the guide.
  • the retainer 4 can interact with the means of the latch suitable for keeping the drawer closed, regardless of whether these are magnetic, mechanical, or other.
  • the moving guide 5 moves in the direction of the arrow "C", and a rib of the retainer 4 pushes the shank 6 of the latch 1, positioning it as shown in Fig. 2.
  • the magnet 7 holds the retainer 4 against the latch 1 that, since it is locked in this position, keeps the drawer shut.
  • a slight pushing force must be applied to the drawer. This causes the rib 4 to move the shank 6, releasing it from its retainer which is not shown in the figures.
  • the latch returns the elastic energy stored when closing the drawer, and this energy is transformed into a force that pushes the moving guide 5 in the opening direction.
  • the elastic means comprise, for example, an extension spring 8 fastened to one end by a retainer 9 of the fixed guide 3 and to the end by a retainer 10 of the moving guide 5.
  • This spring 8 is responsible for integrating the opening pushing force of the drawer.
  • the spring 8 provides a force that integrates the one exerted by the latch in order to increase the opening stroke of the drawer or complete the opening of the drawer until the limit stop.
  • the spring is sized to make it compatible with the locking force of the aforementioned reversible retaining means of the drawer for example, mechanical or magnetic means.
  • the opening and/or closing device in accordance with the invention can also be made with different embodiments of the latch in different sizes.
  • the shank 16 is longer than the one 6 shown in Fig. 1.
  • This version makes it possible to eliminate the additional spring 8 for facilitating the opening of the drawer since the elastic part is integrated with the latch and increases the stroke of the shank, resulting in a greater drawer-opening movement.
