Hinges that take to pieces

Claim 2

A hinge that takes to pieces, comprising a male and a female part which move around an axis, the male part comprising two retractable pivots which can be inserted into a corresponding housing in the female part, the female part comprising a framework having a cavity to house the male part and adapted to receive two stops, each stop having a housing in the axis of the hinge and being held in position by a cross-piece perforated opposite the housing for the stop, each cylindrical cavity in the female part terminating in two spherical ends each receiving a stop, these two stops being held in position by the common crosspiece, the male part being made up of a fastener terminated by a body lodging in the cavity in the female part and having at each end a retractable pivot adapted so that it can be inserted into the housing in the corresponding stop, the male part having a perforation receiving the two pivots which are separated by a spring and each pivot comprising a projecting pin adapted to slide in the groove on the cylindrical body, the latter having at least one slot for blocking each pin of each pivot in a blocking position and in a position in which the pivot is retracted.

Claim 3

A hinge that takes to pieces in accordance with claim 1, in which the groove is oblong-shaped and has at its sides and near its middle a slot of perceptibly the same width as the pin in order to allow this pin to be blocked in the corresponding position.

Claim 4

A hinge that takes to pieces, comprising a male and a female part which move around an axis, the male part comprising two retractable pivots which can be inserted into a corresponding housing in the female part, the female part comprising a framework having a cavity to house the male part and adapted to receive two stops, each stop having a housing in the axis of the hinge and being held in position by a cross-piece perforated opposite the housing for the stop, each cylindrical cavity in the female part terminating in two spherical ends each receiving a stop, these two stops being held in position by the common cross-piece, the male part being made up of a fastener terminated by a body lodging in the cavity in the female part and having at each end a retractable pivot adapted so that it can be inserted into the housing in the corresponding stop, the male part having a perforation receiving the two pivots which are separated by a spring, at least one of the pivots having a means for blocking the pivot in relation to the female part; at the same time leaving it free to rotate in relation to the hinge, as well as recall means to bring back the male anD female parts into a specific relative position after the hinge is opened.

Claim 5

A hinge that takes to pieces, comprising a male and a female part which move around an axis, the male part comprising two retractable pivots which can be inserted into a corresponding housing in the female part, the female part comprising a framework having a cavity to house the male part and adapted to receive two stops, each stop having a housing in the axis of the hinge and being held in position by a cross-piece perforated opposite the housing for the stop, each cylindrical cavity in the female part terminating in two spherical ends each receiving a stop, these two stops being held in position by the common cross-piece, the male part being made up of a fastener terminated by a body lodging in the cavity in the female part and having at each end a retractable pivot adapted so that it can be inserted into the housing in the corresponding stop, the male part having a perforation receiving the two pivots which are separated by a spring, at least one of the pivots having a means for blocking the pivot in relation to the female part; at the same time leaving it free to rotate in relation to the hinge, as well as recall means to bring back the male anD female parts into a specific relative position after the hinge is opened.

Claim 6

A hinge in accordance with claim 3, in which at least one of the pivots has a truncated part coming to be housed in a correspondingly-shaped cavity in the stop, the part of the pivot free to rotate in the cylindrical body being connected to a recall component resting against the cylindrical body.

Claim 7

A hinge that takes to pieces in accordance with claims 3, in which the recall component and the blocking component are made up of a single helicoidal spring, one end of which is attached to the non-truncated part of the pivot and the other to a component blocked in rotation and, if need be, in translation in the cylindrical body.

Claim 8

A hinge that takes to pieces in accordance with claim 3, in which the non-truncated parts of the two pivots are connected by a helicoidal spring, each end of this spring being attached to the corresponding non-truncated part of the pivot.

Claim 9

A hinge that takes to pieces in accordance with claim 3, in which the components blocked in rotation and in translation in the cylindrical body, and serving as a support for the compression and pivot recall spring, are attached to a guide-rod on which slides a component whose ends are filled with pins or forks to lodge in a corresponding groove in the non-truncated part of the pivots in order to block the latter in their retracted position in the cylindrical body.
