A concealed hinge assembly for use with doors, hinged plates or the like comprises a mounting plate and a projecting base member connected to the mounting plate. A hinge bracket is screw-connected to said base member adjacent to one end of said hinge bracket and at its other end is so connected to one side of a pot-shaped member that the one end of the hinge bracket enters the pot-shaped member during the closing movement. A slider which is biased by two parallel coiled compression springs is guided in the pot-shaped member in a radial plane and carries a cam, which during the closing movement cooperates with a projection or the like carried by the hinge bracket. To ensure that the cam will engage the hinge bracket with a relatively large lever arm during the final phase of the closing movement, the slider is U-shaped and comprises a crosspiece and side legs, which are guided in mating recesses of the pot-shaped member and at their free ends are provided with inwardly extending angled portions or projections, which are engaged by the compression springs at one end thereof whereas the compression springs bear at their other end on abutments consisting of stops carried by the pot-shaped member. The crosspiece carries the cam. One end portion of the hinge bracket extends beyond the projecting base member and runs up and slides on the cam during the closing movement. |
