Abstract:
@ A pivot bearing between first and second components (10,11) each of which is formed from a metal material. The pivot bearing comprises a hollow annular boss (14) which is formed as an integral part of the first component (10) by being drawn from the base material from which the first component is formed. An opening (12) is provided in the second component (11) and the annular boss (14) is pivotally located within the opening. The free end portion (18) of the boss (14) is pressed over such that the cross-sectional area of the free end is greater than the opening (12) thereby pivotally retaining the second component (11) on the annular boss (14). A wear-resistant plastics bushing comprising a sleeve (25) and a flange (16) can be positioned within the bearing and placed under pressure by the coupling of the components to create a required level of friction within the bearing.
Abstract:
A pivot joint for pivotally coupling two components (10 and 11) where at least one of the components is movable relative to the other. A first component (11) is formed of a plastics material and has a projecting hollow spigot (12) the spigot being engaged within an opening (14) in the second component (10). In order to effect the pivotal mounting of the first component (11) with the second component (10) the free end of the spigot is deformed to have a diameterwhich is largerthan the diameter of the opening (14) in the second component (10). Deformation of the free end of the spigot (12) is preferably carried out by a headed fastening (13) being inserted into the bore of the hollow spigot.
Abstract:
A hinge device for rotatably moving a closing element (D), comprising a fix element (11) anchorable to the stationary support structure (S) coupled to a movable element (10) anchorable to the closing element (D) for rotating around a first longitudinal axis (X) between an open position and a closed position. The device further includes at least one slider (20) movable along a respective second axis (Y) between a compressed and an extended position. One between the movable element (10) and the fix element (11) includes at least one operating chamber (30) defining the second axis (Y) so as to slidably house the slider (20), the other element comprising a pivot (40) defining the first axis (X). The pivot (40) and the slider (20) are reciprocally coupled so that to the rotation of the movable element (10) around the first axis (X) corresponds the sliding of the slider (20) along the second axis (Y) and vice versa.
Abstract:
A hinge for hinging a closure member (1) to a support (2), the hinge comprising: a first hinge member (4); a second hinge member (5) pivotably mounted on the first hinge member (4) through the intermediary of two rolling bearings (13, 14) that are placed between different abutments (23, 24, 25, 26); a damping mechanism for damping a closing movement of the closure member (1); and an energy storing mechanism for storing energy when opening the closure member (1) and using the energy to close the closure member (1). As such, one of the rolling bearings (13, 14) will support (2) the weight of a right-handed closure member (1) while the other of the rolling bearings (13, 14) will support (2) the weight of a left-handed closure member (1) if the first hinge member (4) is always fixed to the same element. As such, the hinge is able to be formed as a barrel hinge having only two knuckles which is a compact hinge.
Abstract:
A hinge device has a first part and a second part, which are intended to be attached to a door frame and a door, respectively. The first part and the second part are rigidly connected to each other and have each a tubular housing, whose center axis defines a first hinge axis and which accommodates two balls, an axially displaceable locking member arranged axially inwardly of each ball, a compression spring arranged between and cooperating with each ball and the associated locking member, and an eccentric located between the two locking members and cooperating therewith. Each eccentric is rotatably carried about a transverse axis in the respective housing and rotatable between an initial position, in which the two associated locking members are located in an axially inner position and the two associated balls are located in a position slightly projecting from the housing, in which position they are held biased by the respective compression spring, and an active position, in which the two associated locking members are located in an axially outer position, in which they abut against the respective ball axially locking it in the projecting position.
Abstract:
An Anuba concealed hinge for rotatable moving a door, in particular a reinforced door, connected to a tubular support structure, which includes a rear counterframe anchored to a wall and a front frame anchored to the counterframe The hinge includes a lower fixed half-hinge and an upper movable half-hinge rotatably coupled to each other for rotating about a first longitudinal axis between an open position and a closed position. The lower fixed half-hinge includes a box-shaped hinge body to be concealedly inserted within the tubular support structure. The upper movable half-hinge includes a connecting plate connected to the door to extend from the tubular support structure in the open position and to concealedly retract within the tubular support structure in the closed position. The movable half-hinge includes a pivot defining the first axis unitarily connected to the connecting plate. The hinge body (11) includes a seat internally housing the pivot.

Abstract:
A hinge device for rotatably moving a closing element ( D ), comprising a fix element ( 11 ) anchorable to the stationary support structure ( S ) coupled to a movable element ( 10 ) anchorable to the closing element ( D ) for rotating around a first longitudinal axis ( X ) between an open position and a closed position. The device further includes at least one slider ( 20 ) movable along a respective second axis ( Y ) between a compressed and an extended position. One between the movable element ( 10 ) and the fix element ( 11 ) includes at least one operating chamber ( 30 ) defining the second axis ( Y ) so as to slidably house the slider ( 20 ), the other element comprising a pivot ( 40 ) defining the first axis ( X ). The pivot ( 40 ) and the slider ( 20 ) are reciprocally coupled so that to the rotation of the movable element ( 10 ) around the first axis ( X ) corresponds the sliding of the slider ( 20 ) along the second axis ( Y ) and vice versa.
