Hinge that takes to pieces

Claim 2

A dismountable hinge, comprising a female part provided with a fastening means inserted into the door or the like frame and an open cylindrical cavity terminated, at each end, in the direction of the pivoting axis, by a housing; two stops, placed into the housings of the cavity being held separated herein, and having opposite endfaces provided with axial receivers and defining with one another and the cavity a free space; a male part, provided with a fastening means fitted on the door leaf and a cylindrical element placed, in a pivoting manner, inside said free space of the female part, said cylindrical element comprising an axial drilling open at the faces of the element opposite the respective endfaces; and retractable pivots, submitted to the action of an elastic element, these pivots being located in the axial drilling of the cylindrical element and being partially projected into the respective receiver.

Claim 3

A hinge according to claim 1, wherein the stops are held parted by means of a cross-piece whose ends have been bent back at right angles, so as to form legs which are supported by the stop endfaces, these legs having respectively an axial outlet the diameter of which is at least equal to that of the stop receivers.

Claim 4

A hinge according to claim 1, comprising two pivots slidably located in said drilling, said elastic element being a separating spring also located in said drilling between the two pivots.

Claim 5

A hinge according to claim 1, wherein the male part comprises a slit which is parallel to the axis of said drilling and communicates with the latter so as to permit at least the lower part of the pivot to appear.

Claim 6

A dismountable hinge, comprising a female component including a shell provided with a cylindrical cavity having spaced end portions and an open side intermediate the same, first mounting means for mounting said shell on one of two structural elements, and a pair of stops each received in one of said end portions and having respective juxtaposed endfaces each provided with a recess; and a male component cooperating with said female component and including a cylindrical element turnably accommodated in said cavity intermediate said endfaces and provided with an open-ended axial bore registering with the respective recesses, a pair of retractable pivots slidably accommodated in said bore, biasing means in said bore acting upon said pivots and urging the same partially beyond said bore and into the respective recesses, and second mounting means on said cylindrical element for mounting the same on the other of said two structural elements.

Claim 7

A dismountable hinge, comprising a female component including a shell provided with a cylindrical cavity having spaced end portions and an open side intermediate the same, first mounting means for mounting said shell on one of two structural elements, and a pair of stops each received in one of said end portions and having respective juxtaposed endfaces each provided with a recess; and a male component cooperating with said female component and including a cylindrical element turnably accommodated in said cavity intermediate said endfaces and provided with an open-ended axial bore registering with the respective recesses, a pair of retractable pivots slidably accommodated in said bore, biasing means in said bore acting upon said pivots and urging the same partially beyond said bore and into the respective recesses, and second mounting means on said cylindrical element for mounting the same on the other of said two structural elements.

Claim 8

A hinge as defined in claim 5; and further comprising retracting means operatively associated with said pivots and accessible via said open side for enabling retracting of said pivots into said bore counter to the action of said biasing means.

Claim 9

A hinge as defined in claim 5; and further comprising a substantially U-shaped bracket accommodated in said cavity and having a pair of arms each interposed between one end of said cylindrical element and the associated endface, said arms each having an aperture registering with said bore and the respective recess and having a diameter at least equalling that of the latter.

Claim 10

A hinge as defined in claim 5, said biasing means comprising an expansive spring located intermediate and bearing upon said pivots.

Claim 11

A hinge as defined in claim 5; further comprising an axially extending slit in said cylindrical element and communicating with said bore and said open side; and retracting means operatively associated with said pivots and accessible via said open side and said slit for enabling retracting of said pivots into said bore Counter to the action of said biasing means.

Claim 12

A hinge as defined in claim 9, said retracting means comprising a pair of peripheral grooves each provided in one of said pivots and accessible through said slit.

Claim 13

A hinge as defined in claim 7, each of said endfaces being provided with an annular groove encircling the associated recess, and said arms each having an annular bead encircling the respective aperture and removably accommodated with a snap-action in a respective one of said annular grooves.
