Definitions

  • the present invention refers to a compact damped hinge .
  • snap hinges are widely used for opening and closing furniture doors and leaves and usually comprise a cup- shaped part to be reces sed in the door of the piece of furniture , a hinge flap hooked to a hinge fixing plate designed to be fixed to a shoulder of the piece of furniture , articulation means to connect the hinge flap and the hinge cup to each other in an operatively connected manner and elastic means to ensure snap closing of the hinge , thus preventing the doors from opening on their own in an undesirable manner .
  • the hinges have been provided with damping devices which damp and/or slow down the closing movement of the door, preventing it from banging shut .
  • the ob j ective of the above solution is to ensure that the door of the piece of furniture , which has a snap closing movement due to the elastic return action exerted by the elastic means during the hinge closing movement , has a door closing movement braked or slowed down by the action of a damper, thus preventing the door from banging shut .
  • the damping devices used are of the type with damped fluid piston and can be fixed to the piece of furniture in positions such as to be directly operated by the doors during the last stretch of their closing movement .
  • the general ob j ect of the present invention is to provide a compact damped hinge able to solve the above-mentioned drawbacks of the known art in an extremely simple , inexpensive and particularly functional manner .
  • a further ob j ect of the present invention is to provide a hinge in which the activation of the damper is simplified and simple .
  • FIGS. 1 and 2 are two perspective views in which a hinge according to the present invention is shown in the closed position and in the open position respectively;
  • figure 3 is a perspective view, partially split , of part of the hinge shown in the closed position of figure 1 ;
  • figure 3B is a perspective view, partially split , according to a dif ferent angle from figure 3 , of part of the hinge shown in the closed position of figure 1 ;
  • figure 4 is an enlarged perspective view of part of the hinge of figure 3 which highlight s the connecting rods , the damper device , the shaped elastic sheet and their reciprocal position with the hinge closed;
  • figure 5 shows in a perspective view only the lower connecting rod;
  • figure 6 shows in a perspective view only the shaped elastic sheet in the rest position ;
  • figure 7 shows in a perspective view an enlarged detail of the
  • an embodiment of a compact damped hinge according to the present invention is shown, particularly suitable for opening and closing furniture doors .
  • the compact damped hinge comprises es sentially a hinge cup or box 11 designed to be reces sed by means of a hole 12 , for example circular, formed on an inner surface 13 of a door 14 of a piece of furniture .
  • the hinge further comprises a fixing plate 15 to be f ixed to an inner surface 1 6 of a shoulder 17 of the piece of furniture and designed to receive a hinge flap 18 which engages in a removable manner with the fixing plate 15 .
  • Articulated connection means are further provided designed to connect in an articulated manner a rear end part 1 9 of the cup 11 to a front end part 20 of the hinge flap 18 .
  • the cup 11 and the hinge flap 18 are articulated to each other so as to pas s from a closed hinge configuration ( figure 1 ) to an open hinge configuration ( figure 2 ) , and vice versa .
  • the door 14 supported by the hinge is closed and open with respect to the remaining part of the piece of furniture such as , for example , a shoulder 17 .
  • a spring 21 is also provided that exert s a thrust between a part integral with the hinge flap and a part integral with the cup to generate an elastic return action that set s the hinge to the closed position .
  • the articulated connection means comprise es sentially, observing the hinge in side elevation, an upper connecting rod 22 and a lower connecting rod 23 .
  • the upper connecting rod 22 is pivoted by means of a first pin 24 to the rear end part 1 9 of the cup 11 and by means of a second pin 25 to the front end part 20 of the hinge flap 18 , where the spring 21 is arranged coaxial .
  • the lower connecting rod 23 is pivoted by means of a third pin 2 6 to the rear end part 1 9 of the cup 11 and by means of a fourth pin 27 to the front end part 20 of the hinge flap 18 .
  • the hinge flap 18 has an inverted U-shaped profile and the rear end 1 9 of the cup 11 has sides arranged inside the hinge flap 18 U, both arranged to receive the pins 24 , 25 , 2 6 and 27 .
  • a first embodiment provides a damper device 28 comprising a body 2 9 and a stem 30 , arranged in a direction longitudinal to that of the hinge flap 18 .
  • the damper device 28 is positioned and operated by a shaped elastic sheet 31 , arranged and functioning as will be seen, which causes loading or discharging of the damper device 28 .
  • the damper device 28 is arranged abutted between an end fold 32 ( or front extension ) of the hinge flap 18 and a final square-folded extension 33 of the elastic sheet 31 ( figures 3 , 3B ) . More in part icular the end fold is formed extending upwards , in the upper surface 38 of the inverted U- shaped profile in the front end 20 of the hinge flap 18 , above the area between the two pins 25 and 27 .
  • the shaped elastic sheet 31 present s a flattened element provided centrally with two flaps 34 spaced apart and converging to form a housing and a centring for the body 2 9 of the damper device 28 .
  • the shaped elastic sheet 31 at rest has a first curved end 35 , whereas at the opposite end it is provided, as mentioned, with the final square-folded extension 33 .
  • two openings 36 are formed on opposite sides thereof , each provided with an elastic tooth 37 facing the inside of said opening 36 .
  • the lower connecting rod 23 receives the fourth pin 27 in holes 39 formed in two ears 40 which extend from said lower connecting rod 23 as drilled extensions spaced apart at the transverse ends of said lower connecting rod 23 .
  • These two ears or extensions 40 namely the lower connecting rod 23 , each have, at the top, rounded surfaces 41 which face each other beneath the curved end 35 of the shaped elastic sheet 31 .
  • teeth 42 extend from said rounded surfaces 41 of each of the two ears 40 .
  • Each tooth 42 has an enlarged end 43 and a bevelled side surface 44 .
  • Said enlarged end 43 is designed to be inserted in a respective opening 36 of the curved end 35 of the shaped elastic sheet 31 flexing the elastic tooth 37 therein ( figure 7 ) .
  • the flexed elastic tooth 37 of the opening 36 springs back to the extended position and blocks the enlarged end 43 in the opening 36, arranging itself beneath it .
  • the other tooth 42 namely the teeth 42 which extend above the lower connecting rod 23 are made integral with the shaped elastic sheet 31 .
  • this shaped elastic sheet 31 in addition to being supported partly on the rounded surfaces 41 of the ears 40 of the connecting rod 23 , also rests on a supporting pin 45 arranged pas sing through side walls 4 6 of the inverted U-shaped profile that forms the hinge flap 18 , said supporting pin 45 being parallel to the above-mentioned pins 25 , 27 arranged in said hinge flap 18 .
  • the shaped elastic sheet 31 has it s curved end 35 at rest ; as it translates on the supporting pin 45 it straightens , allowing the stem 30 of the damper device 28 to come out of the body 2 9 due to the away movement of the final square-folded extension 33 to it s maximum stroke within the hinge flap 18 .
  • a container 50 is arranged, for example made of plastic, which contains the damper device 28 .
  • the elastic sheet 131 in addition to being constrained to the end of the lower connecting rod 23 by means of the teeth 42 , to have for example openings 51 and 52 having shape and position complementary to extensions 53 and 54 formed protruding beneath the container 50 .
  • the arrangement of the container 50 integral with the elastic sheet 31 is obtained by engagement of the extensions 53 and 54 in the re spective openings 51 and 52 .
  • the damper device is positioned inside a plastic container 50 avoiding contact between steel and metal .
