Definitions

  • This invention refers to a hinge with a quick fastening, by means of an expansion plug, to furniture units.
  • the invention also refers to a fastening element.
  • They generally consist of an external element made of plastic material which expands elastically inside a hole in the furniture, to ensure anchorage, following rotation therein of a cam-shaped pin or a screw.
  • the expansion plug can return to its initial dimensions due to the elasticity of the material, thereby enabling it to be removed from the hole.
  • This fastening system for example enables the door to be rapidly fitted onto the piece of furniture directly on the premises of the end user.
  • the pin is usually shifted from the position in which the expansion plug is inserted to the position in which it is secured in place (and vice versa) by inserting a screwdriver into the head of the pin provided with a normal linear slot or a cross.
  • Pins with this type of head however have the drawback of not allowing their angular position inside the expansion plug to be visually recognizable, and consequently it is not possible to know for certain the exact condition (expanded or contracted) of the latter.
  • the general scope of this invention is to obviate the aforementioned problems by providing a hinge with expansion plug type fastening elements which is easy to fit in place without tools and which renders its blocked condition inside the cavity in the furniture unit immediately visible, so as to enable the hardware element to be quickly and firmly secured.
  • a further scope of this invention is to obtain a hinge with expansion plugs, which has its opening and closing movements inhibited unless it is correctly secured, to prevent the possibility of unintentional incorrect fastening of the hinge itself.
  • a furniture hinge provided with elements for fastening it to a furniture unit, said elements being composed of at least one expansion plug radially expansible by rotation therein of a pin inserted in its axial housing and rotatable between a first position in which the expansion plug is not expanded to enable it to be fitted in a hole in the furniture unit and a second position in which the expansion plug is expanded to anchor it in the hole, characterized by the fact that the pin of the expansion plug is provided with a head which extends into a control tab protruding radially to the axis of the pin itself.
  • a fastening element for fastening hardware elements to furniture units, comprising an expansion plug which expands radially by rotation therein of a pin inserted in its axial housing and rotatable between a position in which the expansion plug is not expanded to enable it to he fitted in a hole in the furniture unit and a position in which the expansion plug is expanded to anchor it in the hole, characterized by the fact that the pin of the expansion plug is provided with a head which extends into a control tab protruding radially to the axis of the pin itself.
  • a hinge 10 of the otherwise known type for example of the four-bar linkage type, comprises two fastening elements, for example a known cup-shaped element 11 to be flush-mounted in the thickness of a door 19 and a wing-type element 12 to be secured by known means to a furniture unit, not shown here.
  • the two elements 11, 12 are hinged together in a wholly known way, for example by means of a four-bar linkage composed of two connecting rod elements 13, 14 hinged to the cup 11 and to the wing 12 by means of the pins 15, 16 and 17, 18, respectively.
  • Fig. 3 the same hinge 10 is shown in the open position.
  • the hinge comprises expansion plugs 20 secured, in correspondence with apertures 21, in lateral protrusions or casings 22 of the cup, to be inserted in holes 23 made in the thickness of the door 19, as can be clearly seen in Fig. 1.
  • the expansion plug advantageously comprises a rectangular protruding upper edge 26 which is received in a lower cavity in the protrusion 22 so as to rest on the edge of the cavity and prevent rotation of the expansion plug with respect to the cup 11.
  • each expansion plug 20 Inserted inside an axial housing 24 in each expansion plug 20 is a cam-shaped pin 25 for expansion of the plug by rotation.
  • the pin is provided, according to the teaching of this invention, with a head which extends through the corresponding hole 21 and protrudes above the casing 22 of the cup with a control tab 27 protruding radially to the axis of the pin itself so as to be disposed parallel to the area of the casing 22 forming two wings for fastening the hinge.
  • the tab 27 can be made in one piece with the pin 25 or be moulded separately (for example, from plastic) and rendered integral with the pin by glueing or by other methods known to the expert in the art.
  • the tab 27 offers easy manual control to rotate the pin between a non-operative or non-expanded position (shown by the continuous line in Fig. 3) and an operative or expanded position (shown by the broken line in Fig. 3). Moreover, the expanded and non-expanded conditions of the expansion plugs are immediately recognizable.
  • the expanded and non-expanded positions can advantageously be made according to a specular conformation with respect to the centre line of the hinge and with a size contained within the dimensions of the cup, so as to avoid elements protruding beyond the contours of the casing of the cup.
  • the tabs 27 extend towards each other for such a distance as to interfere, as can be clearly seen in Fig. 1 and in Fig. 3, with the movement of a portion of the hinge (for example the hinge pin 16 of the wing 12, made protruding laterally) from the position housed inside the cup 11 (hinge closed) to the external position (hinge open) and vice versa.
  • a portion of the hinge for example the hinge pin 16 of the wing 12, made protruding laterally
  • This embodiment offers a dual advantage. First and foremost it prevents a hinge fitted, in the closed position, onto a door, but not secured correctly by means of expansion plugs, from being shifted to the open position to be fitted onto the furniture unit. Moreover, the tabs hinder the closing of a fitted door, whose hinge has an expansion plug which has been accidentally or intentionally loosened.
  • the tabs 27 can also advantageously be provided with means for locking them in the position in which the plug is expanded, for the purpose of preventing accidental rotation of the pins in the direction of contraction of the expansion plugs, with the consequent danger of detachment of the hinge from the door.
  • Said means can for example consist of protrusions 28 on the tabs, which can be removably made to snap-fit into corresponding holes 29 in the casing 22 of the cup by exploiting the flexibility of the tabs 27.
  • Fig. 4 shows an expansion plug 20 fitted, in the expanded position, with the pin 25 provided with tabs 27 according to the invention.
  • the pin 25 can be advantageously provided with a shank 30 widened in a crosswise direction to the axis to define a portion with side walls 32 diverging towards its free end.
  • the axial housing 24 of the expansion plug 20 has walls diverging in the same direction to constitute contact surfaces 31 with the side walls of the pin 25 when the latter is in the position in which the expansion plug is expanded.
  • the contact surfaces of the pin and the expansion plug have substantially the same angle of inclination with respect to the axis of the expansion plug itself when the expansion plug is expanded.
  • the number and position of the expansion plugs securing the hinge may differ from that described herein.
  • fastening elements described herein may be used for fastening different types of hinges from the ones generically represented.
