Abstract: Providing an article equipped with an overturn preventing device, which can add an overturn preventing function to the article itself and can reduce work burdens and management burdens at the time of the mounting. A piece of furniture includes a furniture body to be disposed between an installation surface and a ceiling at a time of installation and an abutting member to be disposed between the ceiling and the furniture body at the time of installation. The furniture further includes an operating part having a damper having two ends one of which is coupled to the furniture body and the other of which is coupled to the abutting member. The operating part is operated such that the damper becomes a contracted state when the abutting member is disposed at an initial position near the article body side and that the abutting member is moved to a developed position upwardly farther away from the furniture body than the initial position according to extension of the damper thereby to be caused to abut against the ceiling.

Abstract: Providing an overturn preventing device which can easily be mounted between a top surface of an article and a ceiling and a method of mounting the overturn preventing device. The overturn preventing device includes a damper. The damper is mounted between a top surface of a piece of furniture (an article) and a ceiling. The damper includes a cylinder and a piston. A hydraulic fluid (operating liquid) and a compressed gas are enclosed in the cylinder. The piston is slidably housed in the cylinder. When the damper is to be mounted between the top surface of the furniture and the ceiling, the piston is housed in the compressed gas enclosed above the hydraulic fluid. The piston can be moved into the hydraulic fluid when the furniture is tilted and the damper is contracted by a predetermined length.

Abstract: The overturn preventing device includes a damper, a length adjusting member and a pair of bases. The damper has a cylinder having an outer peripheral surface formed with a screw thread, and a rod. The cylinder is bottomed. The rod is inserted. into the cylinder and has a distal end protruding out of an open end of the cylinder. The length adjusting member has a first end and a second end. The first end has an opening. The length adjusting member has an inner peripheral surface formed with a screw thread so that the cylinder is screwed through the first end into the length adjusting member. The bases are rotatably coupled to the second end of the length adjusting member and the distal end of the rod respectively. The bases abut against a top surface of an article installed. on an installation surface and a ceiling respectively.

Abstract: A fluid pressure control device includes a load holding mechanism that is configured to hold the load pressure of the load side pressure chamber. The load holding mechanism includes a switching valve having a communication passage configured to be blocked from the third pressure chamber by the second land section in a case where the spool is closed, and providing communicate between the second supply port and the discharge port in accordance with the movement of the spool in the valve opening direction. In a case where the spool is moved in the valve opening direction, at the same time when or after the second supply port communicates with the discharge port via the communication passage, the first land section is brought into sliding contact with the annular projecting section and the first supply port and the discharge port are blocked from each other.

Abstract: A suspension device includes a fluid pressure circuit disposed between a damper, a pump, and a reservoir. The fluid pressure circuit includes an extension-side damping valve disposed in an extension-side passage, a contraction-side damping valve disposed in a contraction-side passage, and a suction passage that connects a discharge path to a supply passage at a point between an electromagnetic throttle switching valve and a supply-side check valve. The suspension device further includes a control unit configured to control the electromagnetic throttle switching valve on a basis of a differential pressure between the extension-side passage and the contraction-side passage.
