Aprilia, Latina, Italy Filed June 14, 1967, Ser. No. 646,073 Claims priority, application Italy, June 22, 1966, 14,385/ 66 Int. Cl. Ed 3/08 US. Cl. 16-166 5 Claims ABSTRACT OF THE DISCLOSURE A hinge for doors of pieces of furniture generally, including in combination a first connection plate to be fixed to the stationary part and making part of an articulated quadrilateral, two sides of said quadrilateral having one shaped portion extended with at their ends a pin for connecting a second plate to be fixed to the movable part, in this second plate being provided a hole and a guide groove for the insertion of said pins. A slot provided in the first connection plate allows the adjustment of the device.

The present invention relates to a hinge for doors of pieces of furniture, the control linkage of which, even if rotating through 90 only, allows the door to swing through about 180.

The purpose of this invention is that of embodying a device of the related kind, providing various aesthetic and functional advantages, among which are the complete concealing in its shut position, and the possibility for the door of swinging through 180 becoming located, at the end of the opening swing, in a position parallel to the front part of the piece of furniture.

According to this invention a hinge is provided including in combination:

A first fastening plate to be fixed to the stationary part of the piece of furniture and making part of an articulated quadrilateral which includes also a link and two levers provided at the end of a pin;

A second fastening plate to be fixed to the door, wherein are provided: (a) one hole for receiving the pin of one of the above-mentioned levers, serving as a pivot of the door; (b) a groove in the door plate serving the purpose of guiding the pin of the second lever inserted thereinto, for controlling the movement of the door.

An adjustment screw, guided in a slot provided in the first fastening plate, destined to allow the adjustment of the position of the hinge with respect to the side of the furniture, during the mounting operation.

This invention will be now described with reference to the attached drawings showing by way of illustrative and non-limitative example one preferred embodiment of the invention itself.

In the drawings:

FIGURE 1 is a top plane view of the hinge in its shut position, with the door partially removed for the sake of clearness;

FIGURE 2 is a view similar to FIGURE 1, showing the door in its opened position, at 90 with respect to the initial position;

FIGURE 3 shows the door in its completely opened position;

FIGURE 4 is a perspective view of the door, seen from below;

FIGURE 5 is a view similar to FIGURE 3, showing a variation of the groove for guiding the movable plate.

With reference to FIGURES 1 to 3, the reference numeral 1 denotes the bottom of a recess provided in a piece of furniture, defined by the partition 2 and by the door 3.

"Ice

To the bottom 1 is fixed, by the screws 4, the plate 5 whereon are pivoted: at the point 6, the link 8 and at the point 7 the lever 9; both the link 8 and the lever 9 are articulated with respect to the lever 12 at the points 10 and 11.

In the movable plate 15 fixed to the door is provided, a guide groove consisting of a substantially straight portion 16 and of a portion 17 also substantially rectilinear slightly deflected with respect to the previous portion (see FIGURE 4).

In the hole 14 the pin 13 of the lever 12 is rotatably entered, and said pin serves as a pivot for the door, and in the groove 16, 17 slides the pin 18 of the lever 9.

The operation is as follows: starting from the position of FIGURE I (shut) and rotating the door 3 about the pin 13 of the lever 12 clockwise, the same rotation is transmitted by means of the pin 18 sliding in the groove 16 of the plate 15, to the lever '9 and to the link 8 articulated at the points 10 and 11 of the lever 12 causing thus a slight movement of the door away from the wall 2.

Subsequently, the pin 18 slides in the two portions 16 and 17 of the guide, while the door 3 rotates about the pivot 13 moving from the position at (FIGURE 2) to the position at (FIGURE 3).

As shown in FIGURES 2 and 3, the plate 5 is provided with a slot 19 into which a set screw 20 is inserted. The hinge is fixed by means of the two screws 4 (forming the rotation pins of the elements 8 and 9) and the screw 20. The latter serves for adjusting the position of the entire hinge with respect to the side of the piece of furniture. This adjustment allows at the moment of mounting of arranging the edge of the door exactly parallel to the side of the piece of furniture, with no intervention with the chisel for moving the plate 15 of the door 3.

Practically, the upper screw 4 as seen in FIGURES 1-3 is first fixed, then the position adjustment is made by means of the slot 20, and finally the second screw 4 is mounted, which serves to lock the plate 5 in its adjusted position.

FIGURE 5 shows a variation of the guide groove. In that case, the two portions 16 and 17 are straight and circle are shaped with center at 13, respectively.

As shown in dotted line in FIGURE 5, when the door has reached the position at 90 with respect to the starting position (FIGURE 2) and the pin 18 will have moved throughout the entire substantially straight portion 16 of the guide groove, coming thus to the beginning of the circle are shaped groove portion 17, the pin 13 and the pin 18 will be aligned perpendicularly to the front of the furniture. From this point, although all the elements forming the device remain nearly stationary, the door can describe a further swing through about 90 as the pin 18 slides freely in the circle arc groove 17.

The present invention has been described in connection with one preferred embodiment, but it is understood that constructional variations could be practically adopted without departing from the scope of the appended claims.

Having thus disclosed the invention, what is claimed is:

1. A hinge for doors of pieces of furniture, comprising a first connection member to be fixed to the stationary part, a relatively short link pivotally mounted at one end on said first connection member, a relatively long link pivotally mounted at one end of said first connection member a distance from said short link, a lever pivotally interconnected with the other end of said short link and with said long link at a point intermediate the lengths both of said lever and of said long link, a second connection member to be fixed to the door, means pivotally interconnecting the second connection member and the end of said lever which is remote from said short link, said second connection member having a guide groove therein, and a pin on the end of said long link remote from said first connection member, said pin sliding in said guide groove.

2. A hinge as claimed in claim 1, said interconnecting means comprising a hole in said second connection member and a pin on the end of said lever Which is remote from said relatively short link, the last-named pin being rotatably disposed in said hole.

3. A hinge as claimed in claim 1, said first connection member having a slot therethrough and a screw disposed in said slot whereby said first connection member may be secured to said stationary part in an adjusted position.

4. A hinge as claimed in claim 3, in which said relatively short link is pivotally interconnected with said first connection member by means of a screw by which said first connection member can be fixed to said stationary part.
