A sliding door system includes a rail device with a mounting rail mountable in a building, with a guide rail in which at least two carriages that are connected to a sliding door are held displaceable along a guide axis, and with a plurality of coupling devices with which the guide rail and the mounting rail are releasably connected with one another and which comprise a coupling head connected to the guide rail or the mounting rail, that comprises a coupling plate and a coupling neck and that can be anchored in a coupling opening provided in the mounting rail or the guide rail and which comprises a first opening part with a diameter larger than a diameter of the coupling plate, and a second opening part adjacent thereto with a diameter larger than the diameter of the coupling neck but smaller than the diameter of the coupling plate.

Trunk lid stopper mechanism and method for controlling rotational speed of a trunk lid to slow down and halt its movement, and to hold the trunk lid at the halted position. The stopper mechanism comprises hinge arms for supporting the lid, torsion bars for applying biasing force to the lid, and link arms for transmitting biasing force from torsion bars to the hinge arms. Either each hinge arm or link arm is equipped with a stopper member that brakes the rotation movement of the trunk lid and halts the trunk lid fully-open. The stopper member has tapered surfaces for reducing relative rotational speed between the hinge and link arms by being forced therebetween during their relative rotational movement, and a stopper surface(s) for abutting against the other arm and halting the arms' relative rotational movement at the fully open position of the trunk lid.

A roller with a plastic injection tube to coat the steel shaft wherein the plastic coated shaft eliminates the metal-to-metal contact that creates the noise. Further disclosed is an improved roller wheel having a tire made of material selected from the group consisting of urethane and urethane (PER) on which the roller will roll within a garage door track to significantly reduce the noise of the roller as it rolls inside the garage door tracks as the garage door is raised and lowered. The roller shaft has the treads extending to a distal end of the roller shaft where a plastic washer and a closing cover nut with interior threads are threaded onto the distal end of the roller shaft. The closing cover nut with interior threads is selected from an acorn nut with a nylon insert and a hex lock nut with a nylon insert.

A door glass assembly is configured to reduce an impact noise generated when a door glass is moved upward/downward and may include a carrier plate coupled to a glass holder to which a door glass of a vehicle is secured. The carrier plate is installed inside a door of the vehicle so as to be movable upward/downward. A module plate, on which the carrier plate is installed so as to be movable upward/downward, is installed inside the door of the vehicle. A driving motor is provided to move the carrier plate upward/downward. The module plate and the carrier plate are provided with an impact noise preventing means for gradually decelerating and stopping the carrier plate when the door glass is being maximally moved upward or downward.

A sliding doors floor handling device (20) for sliding wooden doors (10) or glass doors (72), placed next to a wall (16) and provided at the bottom with a guide (82) combined with a pin (14) protruding from the floor (48), comprises a containment shell (26), substantially parallelepiped in shape, pardy open along the upper base, in which a fork-shaped frame (44) is arranged. The parallel sections (64) of the frame (44) are provided with a hole (52) for inserting a pin (54) that supports a wheel (46) designed to touch the floor (48) when rolling. The fork-shaped frame (44) is provided with one or more elastic sheets (60) secured to the shell (26).

Provided is a guide bumper for a tailgate, including a first guide member attached to one of a vehicle body and a tailgate, and a second guide member disposed on the opposite side of the first guide member, the first guide member including at least one outer body and at least one elastic core inserted into the outer body.

The present invention relates to a G-sensor for an automobile tray, and more particularly, to a G-sensor for an automobile tray wherein a G-sensor for preventing a tray cover from being opened by an external force generated when the vehicle travels is modularized such that shared use of components can be realized, and at the same time, the G-sensor can be operably installed on the tray through an easy process. The present invention is accomplished by comprising: a lever (120) configured to rotate in one direction and in the other direction around a hinge shaft (121); a slider (140) guided along a key hole (121a) according to the state of rotation of the lever (120) so as to move upward/downward, thereby controlling the state of opening/closing of a tray cover (210); a weight (130) for endowing a rotational moment such that the lever (120) rotates around the hinge shaft (121), and such that the slider (140) can slide; a housing (110) on which the lever (120) is installed to be able to rotate around the hinge shaft (121), the weight (130) and the slider (140) being coupled to the lever (120); and an elastic body (150), such as a spring, installed to provide the lever (120) installed on the housing (110) with power such that the same returns to the original condition.

A pneumatic control device of auto door includes a first directional control valve configured to control a direction of a compressed air supplied to a door cylinder for opening and closing a door, a door detection sensor configured to detect an open/close state of the door, first and second exhaust lines respectively connected to first and second outlet ports of the first directional control valve, and second directional control valves installed in the first and second exhaust lines respectively to operably exhaust the compressed air exhausted from the first and second outlet ports according to an emergency stop signal, and capable of changing positions to reduce an exhaust speed of the compressed air in case that the door is not completely open or closed when an operation signal is generated after the emergency stop signal.

A fluid damper hinge using a fluid damper only and a damper hinge using the fluid damper in combination with a torsion damper, used especially in relation to an opening and closing element such as seat lid and seat for western-style toilet, wherein both have a simple structure, do not require time for assembly and can be manufactured at a low cost.

A door roller mechanism for cooperation with a roller track including a carriage member having a door attachment feature; at least one roller disposed for rotation on a first side of the carriage member when the carriage member moves in the rolling direction; at least one roller disposed for rotation on an opposite second side of the carriage member when the carriage member moves in the rolling direction; a first rub member disposed on the first side of the carriage; a second rub member disposed on the second side of the carriage; and at least one biasing element disposed on the carriage member for resiliently biasing the first rub member and the second rub member in opposite lateral directions so as to contact a respective first track surface and a second track surface in a manner to dampen lateral vibration of a door connected to the roller mechanism.
