Abstract:
A hinge for automatically-closing a door which opens in both directions with a shock absorbing function, which allows installation on a door which opens in both directions and is opened inward and outward, including a cylinder 2; an operating rod 3 attached to one end of the cylinder 2 so as to be rotatable and restricted from moving in the longitudinal direction; two substantially V-shaped grooves 33 provided on an outer periphery of the operating rod 3 in the cylinder 2 so as to oppose to each other; two spheres 55 provided so as to engage the substantially V-shaped grooves 33 and disposed so as to oppose to each other; an upper piston 5 engaged with the spheres 55 and moved in the cylinder 2 in the longitudinal direction in conjunction with the movement of the spheres 55 with respect to the substantially V-shaped groove 33; a compression coil spring 4 disposed between the upper piston 5 and an upper end portion of the cylinder 2 and configured to urge the upper piston 5 to the other end side of the cylinder 2; and a fluid pressure shock absorbing mechanism configured to absorb a shock caused by the movement of the upper piston 5 to the other end side with a liquid pressure.
Abstract:
In a braking apparatus by which braking can be effected to the movement of a door, the entire braking apparatus is formed in a compact structure. The braking apparatus has a main body containing a braking fluid, and a spiral rod. A hollow shaft is rotatably inserted through the main body. The spiral rod is inserted into the hollow shaft, and the main body and the spiral rod are screw-threadably engaged. On the outer face of the hollow shaft, is disposed a resistor which is placed in the braking fluid. The main body is fixed to the door frame, and the spiral rod is fixed to the door. When the door is opened and closed, the spiral rod undergoes straight reciprocating motion in the axial direction, and this motion is converted to the rotational motion of the hollow shaft, and the hollow shaft is rotated under decelerated condition, whereby braking can be effected to the movement of the door.
Abstract:
Dispositif (1) d'entraînement d'un élément mobile (10) d'un bâtiment, comprenant un motoréducteur (2), un rail (4) de guidage en translation d'un chariot (3) en liaison mécanique avec l'élément mobile, un lien souple (5) de transmission de puissance entre le motoréducteur et le chariot, des moyens (103A, 103B, 104, 105, 106, 107, 109) de tension du lien souple et des moyens (109, 108) d'indication de la tension du lien souple, le lien souple formant une boucle et reliant une première (7) et une deuxième roue (8), la première roue étant couplée au motoréducteur et la deuxième roue étant une roue de renvoi, caractérisé en ce que les moyens d'indication de la tension du lien souple présentent des moyens pour déterminer au moins trois valeurs distinctes de tension du lien souple.
Abstract:
Die Erfindung betrifft eine Dämpfungsvorrichtung für bewegliche Möbelteile, beispielsweise für Türen oder Schlubladen, bestehend aus einem in einem Hohlkörper z. B. einem Zylinder, gleitend geführten Kolben oder Stößel, der durch Federkraft in seine aufgeschobene Stellung beaufschlagt ist. Erfindungsgemäß sind der Hohlkörper mit mindestens einem Abschnitt eines wendelförmigen Innengewindestegs und/oder der Kolben oder Stößel mit mindestens einem Abschnitt eines wendelförmigen Außengewindestegs versehen. Die Gewindestege stützen sich gleitend aufeinander ab oder es sich stützen sich jeweils Nocken oder Zapfen des Hohlkörpers oder des Kolbens oder des Stößels auf einem Gewindeabschnitt des anderen Teils ab. Die Steigung der Gewindestege ist größer als diejenige, bei der Selbsthemmung eintritt.
Abstract:
A power drive moves a movable closure (D) between an open position and a closed position with respect to a portal defining a passage through a barrier. The power drive can include an elongated drive member (34) connected to the movable closure and a ball nut drive assembly (64) for selectively moving the drive member longitudinally. The elongated drive member (34) can be a compound drive member having at least one gear or tooth-like member extending helically around in uniformly spaced turns about a core of the drive member to form a rigid or resilient screw-like portion (88) capable of being driven by operable engagement with the recirculating ball nut drive assembly (64). A flexible portion, such as a push/pull cable (90) can be attached to one end of the screw-like member to allow the power drive to move a movable closure along a curved or other non-linear path.
Abstract:
A swivel-sliding door system for a vehicle having at least one door leaf (1a,1b) situated in the vehicle wall (3) in the closed state, and situated on the outside in front of the vehicle wall in the open state while leaving a door opening (2) free, wherein drive means, as well as transverse guide means and longitudinal guide means are provided which enable a movement of the at least one door leaf transverse relative to the vehicle wall (3) and along the vehicle wall, wherein the drive means, the transverse guide means and the longitudinal guide means are combined into one complete operating unit (4) that can, by means of some suitable fasteners (5), be mounted as one whole in the vehicle and be coupled to the at least one door leaf (1a,1b), and wherein the operating unit (4) comprises a frame which, in assembled condition, is fixedly connected to the vehicle and an assembly which is movably provided in the frame and which comprises a drive motor (30) for the door leaf movements.
Abstract:
Rotary locks used on transit vehicle doors (2) when opened and closed by a rotating helical door drive member (40). In a preferred embodiment, a first lock utilizes a negative thread portion (51) of the helical drive (40). A second lock utilizes a rotating lock pawl (22) and stop (23). The drive (40) and lock can be used to operate door systems with and without separate door hangers. Compensation for camber variations in car structure is provided through the use of spherical mounts or drive member journals (35, 38).
Abstract:
The trolley comprises a first hollow element (8) of which the top face (8a) affords a downwardly angled profile (9) designed, once the fixture is erected, to interact with a cam (10) afforded by the topmost part (6a) of a second hollow element (6) such that the first can be shifted in relation to the second. The outer flank faces of the first element (8) also carry a pair of transversely projecting pins (12) insertable in two mutually opposed grooves (13) on the inner flank faces of the second element (6), which are open at the bottom ends and joined at the top ends with two further grooves (14) of profile similar to that of the cam (10); these additional grooves (14) combine with the pins (12) to restrain the second element (6) slidably, and to advantage, removably.
