Abstract: The telescopic hinge comprises a front face element intended to be joined with a side stud extending along the front face of the frame and having a first fastener, and a branch element, intended to be joined with the corresponding branch of the frame and having a second fastener capable of cooperating with the first fastener in order to hold the front face element against the branch element. The telescopic hinge also includes an intermediate fastener capable of cooperating respectively with the first fastener and the second fastener.

Abstract: The invention relates to a motor vehicle having three motors, i.e. an electric motor, hydraulic motor, and heat engine, and to a method for managing the energy stored onboard. The three motors (19, 25, 15) are particularly used for driving the vehicle, and are associated with means for storing electrical energy (21), hydraulic energy (28, 29), and fossil energy (18), respectively. The heat engine (15) is arranged so as to be connected in series and so as to recharge the means (28, 29) for storing hydraulic energy, but not the means (21) for storing electrical energy. During travel, the means (21) for storing electrical energy is not recharged by the heat engine (15) which can recharge the means (28, 29) for storing hydraulic energy of the hydraulic motor.

Abstract: The telescopic hinge (7) comprises a front face element (10) intended to be joined with a side stud extending along the front face of the frame and having a first means of fastening (12, 40), and a branch element (20), intended to be joined with the corresponding branch of said frame and having a second means of fastening (25) capable of cooperating with the first means of fastening (12, 40) in order to hold the front face element (10) against the branch element (20). The telescopic hinge (7) further comprises an intermediate means of fastening (30) capable of cooperating respectively with said first (12, 40) and said second (25) means of fastening.

Abstract: The present disclosure relates to a frame which comprises a front surface, extended by two lateral posts and two arms hinged to the posts about the hinge pins of two telescopic hinges, each of which, with a front surface element rigidly connected to a post and an arm element, is rigidly connected to an arm that comprises a slide hinged on the front surface element, and mounted in a sheath against a spring and slidable by means of the latter; the front surface element and the sheath of the arm element engaging, in the open position of the arm, by at least two matching transverse surfaces for stopping the opening. The surfaces that stop the opening of the two elements of each hinge are rough, the surface that stops the opening of one of the elements, of the surface, and of the arm having a hollow intermediate area. Thanks to the present method, system and device, the frame hinges have a reduced size with the same performance.

Abstract: A spectacle frame includes sliding hinges which enable the arms to move from a stable open position, in which the end (306) of the arms is parallel to the end (313) of the endpiece (307), to an unstable wide-open position, by pivoting around a support point (311) belonging to a coincidence plane (P,P?) which passes between the knuckles (C1, C2) of the hinges. The frame, which has a plane of symmetry (X,X?), is characterised in that the support point (311) is located closer to the plane of symmetry (X,X?) of the frame than the outer face (309) of the arms at the coincidence plane (P, P?).

Abstract: The invention relates to a hinge system comprising one end (1) belonging to a first rigid element (7) and one end (3) belonging to a second rigid element (8), said ends having support surfaces which can be matched to one another. According to the invention, elastic means (18) are provided in order to maintain the pressure contact between the aforementioned surfaces. The inventive system also comprises at least one immaterial pivot point which can move in two orthogonal planes within the limits allowed by guide means (6) and means (19a-b) which only authorise pivoting in one plane or in a certain number of planes having a determined orientation.

Abstract: A hinge includes a first rigid element enclosing elastic elements that have at least one elastic end oriented so that the elastic elements extend into a plane perpendicular to the axis of rotation of the hinge. One end of the first rigid element is formed by a knuckle-piece, which is inserted between a pair of knuckles that together constitute the rigid second element. A pin passes through all the knuckles. A bush, disposed between a female hinge of the second rigid element and the pin, defines a peripheral surface which serves as a cam surface, against which at least one portion of the elastic elements is adjusted.

Abstract: An eyeglass assembly for frameless lenses has a plug with an elongate stem placed through a hole in the lens, and a broad head on an upper end of the stem for residing within a seat in the front face of the lens. A lower portion of the stem has a series of annular radial extensions. A cylinder on the end of the temple is lined with a tubular collar made of a deformable material. As the plug is inserted into the collar with force, the extensions grip against the inside of the collar, and are retained by the collar upon release of the force. The head of the plug may be smooth and flat to provide a uniform surface for the lens face.
