A hinge, in particular for furniture doors, of the type in which a wing is designed to be fitted to a base secured to the piece of furniture, comprises an intermediate element for connecting the wing to the base having a substantially U-shaped transverse configuration to determine two rigid sides which laterally embrace the base. The intermediate element is provided with fastening means for securing it to the wing, and unfastenable means connecting it to the base comprising members yieldingly fitted onto the intermediate element in two portions spaced apart from each other in the longitudinal direction of the wing. The yielding members are elastically biased to move into a position in which they engage with complementary housings in the base in order to couple the intermediate element to the latter, the movement of approach between the base and the wing for the coupling being amply indeterminate.
A furniture door hinge comprising a base plate having a raised portion to be secured to a piece of furniture, a hinge arm adapted to support a furniture door and an intermediate element or removably connecting the arm to the base, said arm having a substantially U-shaped cross-sectional configuration forming two lateral side walls which laterally embrace the intermediate element and said intermediate element having a substantially U-shaped cross-sectional configuration forming two lateral side walls that embrace two lateral side surfaces on the raised portion of the base plate, means for fastening the arm to the intermediate element and readily releasable fastening means for coupling the intermediate element to the base, said releasable fastening means comprising a pair of members yieldably mounted in said intermediate element at spaced apart locations in the longitudinal direction of the side walls of the element for movement between a disengaged position and an engaged position where the element is coupled to the base, spring means biasing the members toward the engaged portion, a pair of opposed protrusions at opposite ends of the raised portion of said base plate, said protrusions forming housings for receiving said members in the engaged position and having a slanting upper surface that slants inwardly and upwardly from the ends of the protrusions, whereby as the intermediate element is pressed down onto the base plate in a direction substantially perpendicular to the base plate, with its side walls embracing the sides of the raised portion of the base plate, the slanted upper surfaces of the protrusions will push the yielding members against the action of the spring means toward the disengaged position until they pass the ends of the protrusions and come to rest in the housings, at least one of said yielding members having a portion that can be manually gripped to force it from its housing in the base plate toward its disengaged position to permit the intermediate element and attached arm to be removed from the base plate,
A furniture door hinge comprising a base plate having a raised portion to be secured to a piece of furnitue, a hinge arm adapted to support a furniture door and an intermediate element for removably connecting the arm to the base, said arm having a substantially U-shaped cross-sectional configuration forming two lateral side walls which laterally embrace the intermediate element and said intermediate element having a substantially U-shaped cross-sectional configuration forming two lateral side walls that embrace two lateral side surfaces on the raised portion of the base plate, means for fastening the arm to the intermediate element and readily releasable fastening means for coupling the intermediate element to the base, said releasable fastening means comprising at least two first coupling elements mounted in said intermediate element at spaced apart locations for movement between a disengaged position and an engaged position where the intermediate element is coupled to the base, spring means biasing the coupling elements into the engaged position, at least two complementary housings located in opposed lateral side surfaces of the raised portion of the base for receiving said coupling elements in the engaged position to thereby couple the intermediate element and attached arm to the base, each of said coupling elements having a portion extending exterior of the intermediate element that can be simultaneously gripped to move said coupling elements to their disengaged position so that the intermediate element and attached arm can be removed from the base plate.
