Definitions

  • the present invention relates to an overturn preventing device.
  • Patent Document 1 discloses a conventional overturn preventing device.
  • This overturn preventing device is mounted between a top surface of a piece of furniture installed on a floor and a ceiling.
  • the overturn preventing device includes a support pillar with a built-in spring and base portions mounted to both ends of the support pillar.
  • Each base portion has a disk-shaped base body and a columnar shaft extending vertically from a center of one side of the base body.
  • the shafts of the base portions are inserted into both ends of the support pillar respectively and at least one of the base portions is disposed so as to be movable forward and backward in an axial direction.
  • the spring applies an elastic force to the base portions which are movable forward and backward in an extending direction of the overturn preventing device.
  • the overturn preventing device is thus mounted between the top surface of the furniture and the ceiling with the support pillar extending vertically and can prevent the furniture from overturn due to quakes of earthquake or the like.

  • the overturn preventing device of the invention may further include a distance regulating member which regulates the overturn preventing tool so that the first and second base portions are away from each other by a predetermined distance when the overturn preventing tool has extended.
  • FIG. 1 is a side elevation of the overturn preventing device of a first embodiment, mounted between a top surface of furniture and the ceiling;
  • FIG. 2 is a side elevation of the overturn preventing device of the first embodiment, maintained in a folded state by connecting tools, with one of the connecting tools being detached;
  • FIG. 3 is a sectional view of the overturn preventing device of the first embodiment, maintained in the folded state by the connecting tools;
  • FIG. 4 is a side elevation of the overturn preventing device of a second embodiment, mounted between the top surface of furniture and the ceiling;
  • FIG. 5 is a side elevation of the overturn preventing device lc of the second embodiment, maintained in the folded state by the connecting tools, with one of the connecting tools being detached;
  • FIG. 7 is a side elevation of the overturn preventing device of the third embodiment, maintained in the folded state by the connecting tools.
  • At least one overturn preventing device 10 of the first embodiment is mounted between a top surface 1 U of a piece of furniture 1 installed on a floor surface (not shown) and a ceiling C while a rear surface 1 B of the furniture 1 is opposed to a wall surface W extending in a vertical direction from the floor surface, as illustrated in FIG. 1 .
  • the furniture 1 is formed into a cuboid shape and has a door, drawers (neither shown) and the like in a front 1 F, so that clothes, accessories and the like can be housed in the furniture 1 .
  • the furniture 1 has a rectangle-shaped horizontal section long in a right-left direction (a depthwise direction in FIG. 1 ). When the overturn preventing device 10 is not mounted on the furniture 1 , the furniture 1 would possibly be tilted in a front direction (rightward in FIG. 1 ) by quakes of earthquake or the like thereby to he overturned.
  • the overturn preventing device 10 includes a damper 20 as a overturn preventing tool mounted between the top surface 1 U of the furniture 1 and the ceiling C, a first base portion 30 , a second base portion 40 , a torsion coil spring 50 , and an angle regulating member 60 .
  • the overturn preventing device 10 also includes connecting tools 70 maintaining the folded state in which the damper 20 is contracted to the maximum so that the first base portion 30 and the second base portion 40 come close to each other.
  • the damper 20 is mounted between the top surface 1 U of the furniture 1 and the ceiling C.
  • the damper 20 has a cylinder 21 , a piston (not shown), a rod 22 and a rod guide (not shown).
  • the cylinder 21 has a bottomed cylindrical shape.
  • the rod guide closes an opening of the cylinder 21 .
  • the piston is slidably inserted into the cylinder 21 .
  • the rod 22 has a proximal end connected to the piston and a distal end side extending through the rod guide outside the cylinder 21 .
  • Operating oil and a compression gas are enclosed in the cylinder 21 .
  • the damper 20 is a compression damper in which a damping force generated during an extending operation is smaller than a damping force generated during a compressing operation.
  • the extending operation of the damper 20 refers to an operation which increases an amount of protrusion of the rod 22 out of the cylinder 21 and an entire length of the damper 20 .
  • the compressing operation of the damper 20 refers to an operation which reduces an amount of protrusion of the rod 22 out of the cylinder 21 and the entire length of the damper 20 .
  • the cylinder 21 has an interior divided by the piston into a rod side pressure chamber in which the proximal end of the rod 22 is housed and a counter-rod side pressure chamber.
  • the piston is formed with an orifice which is a throttle valve communicating between both pressure chambers.
  • the orifice functions as a damping force generator which applies resistance to a flow of the operating oil between the rod side pressure chamber and the counter-rod side pressure chamber with the extending/compressing operation of the damper 20 .
  • the piston is formed with a communication path communicating via a check valve with both pressure chambers.
  • the check valve allows the operating oil to flow from the rod side pressure chamber to the counter-rod side pressure chamber and blocks reverse flow of the operating oil. Accordingly, the damper 20 has two flow paths of the operating oil from the rod side pressure chamber to the counter-rod side pressure chamber during the extending operation, that is, one flow path including the orifice and the other flow path including the communication path. On the other hand, the damper 20 has only one flow path of the operating oil from the counter-rod side pressure chamber to the rod side pressure chamber through the orifice during the compressing operation. Accordingly, the damping force generated by the damper 20 during the extending operation is smaller than the damping force generated by the damper 20 during the compressing operation.
