Abstract:
A door opening and closing device for a slide door, which can be horizontally open and close the slide door by application of a light load and which can be constructed and maintained at low costs. The door opening and closing device has a transmission mechanism for converting through a lever (31) the amount of settlement of a tread plate (21) placed on floor surfaces at positions in front and back of the slide door (12), into a predetermined displacement amount. The tread plate (21) is weight-wise balanced such that the transmission mechanism and settlement of the tread plate due to the weight of an adjustment weight (W) causes the tread plate (21) to float through the lever (31). Up-down movement of the long transmission member (32) presses a drive rotation body (42) to an open door rail (41), and a component force of the pressing force allows the slide door (12) to be opened by application of a light load.
Abstract:
A sliding door device has a first pin body provided, at a floor surface; a guide member provided at the door and having a guide groove in which the first pin body fits when the door is closed; and a second pin body that is provided on the floor surface and can be fit in a door groove formed at the door bottom. When the closed door slides in an opening direction and toward the back side of the wall surface, the guide member moves relatively along the first pin body while the first pin body is fit in the guide groove of the guide member. When the door slides further in the opening direction, the second pin body gets in the door groove of the door, and the door slides along the second pin body while the second pin body is fit in the sliding groove of the door.
Abstract:
An opening and closing mechanism includes a fixed member which has a fixed cam on its side face; a movable member which has a movable cam on an opposing face to the fixed cam, and which is rotatably disposed relative to the fixed member; a case housing the fixed member and the movable member; and a spring applying a force toward the fixed member to the movable member. The movable member has a recess at its radial center, and the first end of the spring is inserted in this recess.
Abstract:
A concealed door hinge has first and second leaf assemblies fittable into respective mortises in an edge of the door and in the door frame. The first leaf assembly has a body, mounting tabs at ends of the body and securable to the door frame or to an edge of the door, and an insert shiftable in the body in a first horizontal direction perpendicular to a face of the assembly. The body is also shiftable relative to the tabs in a second horizontal direction transverse to the horizontal direction and parallel to the face. A swivel mechanism is connected between the second leaf assembly and the insert of the assembly. Adjusters engaged between the insert, the body, and the tabs can relatively secure the insert and body in any of a plurality of positions offset relative to one another in the horizontal directions.
Abstract:
Damping device (30) for hinges (10) for the pivotable articulation of door leaves (12) or door flaps on the carcass of pieces of furniture, in which the hinge has respectively a supporting wall mounting part (18) which can be fixed on the supporting wall (14) and a door leaf mounting part (24) which is pivotably coupled via a linkage mechanism (20; 22) to the supporting wall mounting part and can be fixed on the inner face of the door leaf or flap, and which is preferably constructed as a cup part which is countersunk and engages in a recess in the door leaf or flap and has a laterally projecting fixing flange which bears on the inner face of the door leaf.The damping device (30) has a damper housing which is provided on the door leaf mounting part (24) and which is provided in the cavity thereof with a fluid or gaseous damping medium and a resistance element which is movable relative to the damping medium and is coupled to an actuating element (39) which extends out of the housing. At least during part of the pivoting movement of the mounting parts (18, 24) relative to one another the actuating element is in engaged connection directly or indirectly with the supporting wall mounting part (18) and transmits to the resistance element the relative movement of the mounting parts as they pivot.The damper housing (32) is a separate component which is provided with laterally projecting fixing flanges (38, 46) which can be fixed on the fixing flanges of the door leaf mounting part (24).
Abstract:
The device used to hold a separation element (6), in particular a glass panel, comprises a carriage (1) with a carriage body (11) and at least one wheel (124, 125) which rolls on a running surface (231) of a rail (2). The carriage (1) is releasably connected to a mounting element (3) which is connected to the separation element (6). The mounting element (3) which is mounted laterally on an upper edge (62) of the separation element (6) comprises a guide profile (30) provided with a first guide surface (333) which holds a lower and an upper flange element (114; 115) of the carriage body (11) inserted therein which can be displaced along the first guide surface (333) extending inclined by a first angle (a) relative to the upper edge (62) of the separation element (6) and can be locked in an appropriate position by means of locking elements (35, 92).
Abstract:
A mechanism includes a hook (150) provided with a rectilinear shank (115) sliding in a housing (109) dependent on one (107) of the rigid elements and a co-operating part (103) dependent on the other (108) rigid element, and which is engaged in the recessed zone of the hook (150). At its end opposite the shank, the curved portion of the hook includes a rectilinear extension (152) parallel to the shank, and a sheath (153) is adapted to receive the extension, which is capable of a rectilinear translational movement parallel to the shank (115), while remaining permanently engaged in the sheath (153).
Abstract:
In a damping mechanism for a pivot door arranged in a door frame, comprising a door fixture arranged in or on the door panel, a frame fixture arranged in or on the door frame, a damper arrangement arranged in the door fixture or the frame fixture and a damper arrangement counter part mounted in the frame fixture or in the door fixture, a damper arrangement with a brake catcher provided with a damper member includes a spring element which pulls the brake catcher into the fixture and the damper arrangement counter part includes at least one trigger element which is abutted by the brake catcher during closing of the door, so that the damper arrangement begins to dampen the pivot movement of the door as soon as a fixture part of the door comes into contact with a fixture part of the door frame.
Abstract:
A hinge assembly (200) for joining a cover section (110) to a body section (120) of a foldable electronic device (100) includes a main shaft (10), a rotating member (20), a sliding member (30), and a spring (40). The main shaft has a fixing portion (12) at one end, a deformed shaft portion (14) at its central section, and a distal shaft portion (16) at the other end. The rotating member receives the distal shaft portion, and the rotating member includes an engaging portion (24). The sliding member engages with the deformed shaft portion. The sliding member has a deformed hole (34), engaging with the engaging portion of the rotating member. The spring surrounds the main shaft and elastically biases between the sliding member and the fixing portion. The hinge assembly is modularized, easy to install, and low in cost.
Abstract:
A carriage (1) which serves to hold a panel (4), in particular a glass panel, comprises at least one running element (12) such as a magnet (1200), a wheel (12) and/or a sliding element (120) which is held by at least one corresponding magnetic element (1201) or supported on a running surface (3111) of an at least approximately U-profile or L-profile-shaped rail (3). The rail comprises a central part (32) and one or two lateral parts (31a, 31b), possibly with a foot element (311), on the upper side of which the running surface (3111) is provided. The carriage (3111) comprises one or two carriage parts (1a, 1b; 1c) which can be anchored to the panel (4) by mounting elements (2; 114, 1140; 93, 111), such that the two carriage parts (1a and 1b) can be anchored on the opposing sides (4a, 4b) of the panel (4) in each case by the mounting elements (2; 114, 1140; 93, 111). A one carriage part (1c) is further contemplated, which can be introduced into a groove (45) arranged on the upper side of the panel (4) between the sides (4a, 4b) and anchored there by the mounting elements (2; 114a, 114b, 1140; 93, 111).
