A support arm having a proximate support arm segment, a distal support arm segment, a hinge system; and at least one rotation limit stop secured to the hinge system to limit the extent of angular motion of the proximate support arm segment, the distal support arm segment or both, with respect to the hinge system. The rotation limit stop includes a first stop component and a second stop component slidable with respect to the first stop component. When the second stop component encounters a contact point on one of the support arm segments, the angular motion of the arm segment with respect to the hinge system is at a maximum. The second stop component can be secured in a plurality of positions with respect to the first stop component by an adjustment component.

An electronic device is provided. The electronic device includes a housing including first and second housings, a display including a first display region connected to the first housing and a second display region connected to the second housing, and a hinge module connected to the first housing and the second housing. The hinge module may include a rotation bracket including a first accommodation space providing a first rotation axis and a second accommodation space providing a second rotation axis, a rotation member including a first rotation member connected to the first display region and a second rotation member connected to the second display region, and a rail member including a first rail member connected to the first rotation member and configured to rotate in the first accommodation space, and a second rail member connected to the second rotation member and configured to rotate in the second accommodation space.

A hinge device includes a support member, a pivotable member supported by the support member, a first gear located at one of the support member and the pivotable member, a second gear located at the other of the support member and the pivotable member, a friction member configured to apply rotational frictional resistance to the second gear, and means for disengaging. The pivotable member is configured to pivot about a pivot axis between a closed position and a different position where the pivotable member is in a position that is different from the closed position. The second gear is configured to rotate in engagement with the first gear based on pivoting of the pivotable member. When the pivotable member is at the closed position, the means for disengaging disengages the first gear and the second gear from each other.

An electronic device according to one embodiment may include: a first housing including a first side; a second housing including a second side facing the first side; at least one first magnetic member configured to be rotatably disposed inside the first housing and adjacent to the first side; and at least one second magnetic member configured to be rotatably disposed inside the second housing and adjacent to the second side, wherein the first housing and the second housing are rotatably coupled to each other by a magnetic force between the at least one first magnetic member and the at least one second magnetic member. Various other embodiments are also possible.

An improved hinge (1; 100; 150; 200; 250; 300) for revolving shutters (A), especially of shower boxes, comprising a structural assembly which includes a strike block (2; 201) defining a substantially vertical main axis (Y) and suitable to be made integral with a fixed or bearing auxiliary structure (A), a pair of shaped flanges (3, 4; 103, 104; 203, 204; 203, 204) opposite, facing and coupled each other through fastening means (5) in such a way as to define a side recess (6) in which the strike block is substantially housed (2; 201), a side groove (7) which communicates with the outside and develops for at least part of the perimeter of the shaped flanges (3, 4; 103, 104; 203, 204; 253, 254) and is suitable to receive a peripheral portion of a revolving shutter (A) of a shower box, and an inner seat (8) hidden from view in which rotation means (9) are stably housed defining an auxiliary axis (Y) parallel to the main axis (Y) of the strike block (2; 201) and cooperating, on one hand, with the strike block (2; 201) itself in such a way as to define a first operative position, in which the revolving shutter (A) closes, remaining stable in position, a room of the shower box, and at least one second operative position, in which the rotating shutter (A), as a result of rotation around the main axis (Y) imparted by a user, opens fully, remaining stable in position, the room of the shower box, and, on the other side, with elastic means (10) suitable to retain the rotation means (9) stably against the strike block (2; 201) at each of aforesaid operative positions. In particular, the elastic means (10) comprise an elastically yielding laminar body (11) shaped in such a way as to substantially embed in its own overall encumbrance the rotation means (9) which include a single idle roller (12; 156) extending for the entire height (H), defined parallel to said main axis (Y), of a head portion (13) of the strike block (2; 201), opposite to the base portion (14) associated with the fixed or bearing auxiliary structure (A).

A 360? pivotal device for an electronic product includes a first pivotal shaft extending along a first axis, a second pivotal shaft extending along a second axis, and a connecting device. The connecting device includes a first supporting seat, a first intermediate shaft, and a second intermediate shaft. The first pivotal shaft, the second pivotal shaft, the first intermediate shaft, and the second intermediate shaft are coupled to the first supporting seat. The connecting device includes a reference plane on which the first axis and the second axis are located. The first intermediate shaft and the second intermediate shaft are located on the same side of the reference plane. Due to arrangement of the pivotal device, the spacing between the first pivotal shaft and the second pivotal shaft can be greatly reduced to reduce the thickness of the electronic product.

An integrated magnetic catch used to hold a horizontal hinged oven door open at a selected set partially open position. A pin and knuckle assembly is used to hold the two plates together and acts as a pivot point. Attached to a stationary plate is a positioning member comprising a housing containing a magnetic material. This positioning member is formed having a preset angle that correlates with the degree that the door is to be opened. When the door is opened and pivoted the first plate of the rotating hinge makes contact with the second plate of the rotating hinge having a positioning member affixed thereto and the magnetic force holds the door open at a selected angle.

According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.

A snap hinge with damped closing includes a first articulated quadrilateral defined by a coupling plate associated with a fixed element, a first lever and a third lever, which are articulated to the coupling plate, and a second lever interposed between the preceding levers and is articulated thereto. A second articulated quadrilateral has a fixing plate associated with a movable element with which are associated and articulated respective ends of the second lever and of a fourth lever, the opposite end of which is associated and articulated with the first lever. The plates have various arrangements with respect to each other, rotating about a substantially horizontal rotation axis as the hinge moves between the open and closed configurations. The hinge has at least one damping element that acts during closing and is interposed directly between the coupling plate and the second lever.
