Abstract: Providing an overturn preventing device which can be easily mounted at an appropriate inclination angle. The overturn preventing device includes a damper, a pair of bases, and an angle regulator. The damper is mounted between a top surface of a piece of furniture installed on an installation surface and a ceiling. Both ends of the damper are respectively coupled to the bases so as to be rotatable about respective rotation axes. The first base abuts against the top surface of the furniture and the second base abuts against the ceiling. The angle regulator is attached to the first base. The angle regulator regulates an inclination angle of the damper.

Abstract: Providing an overturn preventing device which can be easily mounted between a top surface of a piece of furniture and a ceiling and a method of mounting the overturn preventing device. The overturn preventing device includes a damper and a pair of bases. The damper has a cylinder and a piston slidably housed in the cylinder. The damper is mounted between a top surface of a piece of furniture (article) installed on an installation surface and a ceiling. The paired bases are respectively coupled to two ends of the damper. One of the bases abuts against the top surface of the furniture and the other base abuts against the ceiling. The cylinder has an inlet through which a hydraulic fluid (operating liquid) is poured into the cylinder.

Abstract: Providing a damper which exerts a damping force in an entire stroke range and an overturn preventing device which can successfully prevent an article from overturn by equipment of the damper. The damper includes a cylinder, a rod guide, a piston, a rod, and a cylindrical member. In the damper, a hydraulic fluid and a compressed gas are enclosed in the cylinder. The cylindrical member regulates a position of the piston so that the piston is immersed in the hydraulic fluid enclosed below the gas in a state where a bottom of the cylinder is located lower than an opening and the rod protrudes upward from the cylinder and where central axes of the cylinder and the rod are inclined at a predetermined angle with respect to a horizontal plane.

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.

Abstract: Providing an overturn preventing device which can maintain a mounted state against earthquake or the like with multidirectional shaking and thereby can prevent an article from overturn. The overturn preventing device includes a damper and a pair of bases. The damper is mounted between a top surface of a piece of furniture installed on a floor and a ceiling. Both ends of the damper are respectively coupled to the bases so as to be rotatable about respective rotation axes. Furthermore, both ends of the damper are respectively coupled to the bases so as to be swingable in a direction intersecting a rotation direction. The first base abuts against the top surface of the furniture and the second base abuts 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: Providing an overturn preventing device in which a plurality of dampers can be mounted between a top surface of an article and a ceiling and which can suppress increase in working man-hour and increase in an installation space. The overturn preventing device includes a plurality of dampers mounted between a top surface and a piece of furniture installed on an installation surface and a ceiling. The dampers each have first and second ends and all of the first ends are coupled to the article-side base. The second ends of the dampers are coupled to one or a plurality of ceiling-side bases.

Abstract: Providing a construction that can allow a ceiling side base to be relocated easily even after the overturn preventing device has been mounted between a top surface of an article and a ceiling. A grip member is attached to an overturn preventing device including a damper to be mounted between the top surface of the furniture and a pair of bases respectively connected to both ends of the damper. One of the bases abuts against the top surface of the furniture and the other base abuts against the ceiling.

Abstract: Providing an overturn preventing device which can easily be mounted between a top surface of an article and a ceiling. The overturn preventing device includes a damper, a pair of bases and a fixing cord. The damper is mounted between a top surface of a piece of furniture installed on a floor and a ceiling. The bases are respectively coupled to both ends of the damper. The first base abuts against the top surface of the furniture, and the other base abuts against the ceiling. The fixing cord holds the damper in a contracted state in which the damper has a desired length.
