Embodiments 1 to 7 of the anti-tip device embodying the present invention will be described with reference to the drawings.

<Embodiment 1>

As shown in Fig. 1, the anti-tip device of the first embodiment is attached to at least one of the upper surface of the furniture F and the ceiling C. This furniture F is provided such that the back surface faces the wall surface W extending from the floor surface (not shown) in the vertical direction, and is provided on the floor surface. In addition, the furniture F has a rectangular parallelepiped shape, and has a door or a drawer (not shown) on the front side (the right side surface of FIG. 1), and can store clothes, accessories, and the like inside. The furniture F is a rectangular shape in which the horizontal cross-sectional shape is long in the left-right direction (depth direction in Fig. 1). Do not install anti-roll In the case of the reverse device, the furniture F may be tilted or even tilted toward the front (the right direction of Fig. 1) due to the shaking of an earthquake or the like.

As shown in FIGS. 1 and 2, the anti-tip device includes a damper 10, a pair of base portions 30A and 30B, a drop preventing portion 50, and an angle restricting portion 70. Further, as shown in FIG. 7, the anti-tip device includes a fixing cable 90.

The damper 10 includes a cylinder 11, a rod guide (not shown), a piston (piston) (not shown), a piston rod 13, and two joint portions 15 provided at both ends. . The cylinder 11 has a bottom cylindrical shape. The piston rod guide closes the opening of the cylinder 11. The piston system is slidably inserted into the cylinder 11. The base end of the piston rod 13 is coupled to the piston. Further, the piston rod 13 is inserted through the piston rod and the front end side protrudes toward the outside of the cylinder 11. The cylinder 11 is sealed with hydraulic oil and compressed gas. As shown in FIGS. 1 to 3, each of the joint portions 15 is formed by bending a flat metal member. Further, each joint portion 15 is connected to the bottom of the cylinder 11 and the front end of the piston rod 13. Each of the joint portions 15 is formed with a through hole 15A that penetrates in a direction orthogonal to the axis of the damper 10.

The damper 10 is a compression damper which has a smaller damping force generated during the extension operation than a contraction action. Here, the extension operation of the damper 10 refers to an action in which the protruding length of the piston rod 13 protruding from the cylinder 11 and the length of the damper 10 become long. Further, the contraction operation of the damper 10 refers to an action in which the protruding length of the piston rod 13 protruding from the cylinder 11 and the length of the damper 10 are shortened. Further, the damper 10 acts on the expansion force of the compressed gas enclosed in the cylinder 11 in the direction of elongation.

The mechanism for generating the damping force of the damper 10 is a well-known structure, and therefore, illustration thereof will be omitted. The cylinder 11 is internally divided by a piston into a piston rod side pressure chamber that houses the base end portion of the piston rod 13, and a pressure on the opposite side of the piston rod. room. The piston system is formed with a throttle which is a throttle valve that communicates between the two pressure chambers. The restriction hole function acts as a damping force generating portion that generates resistance to the flow of the hydraulic oil between the piston rod side pressure chamber and the piston rod opposite pressure chamber accompanying the expansion and contraction operation of the damper 10 Attenuation force. Further, the piston system is formed with a communication passage that communicates between the pressure chambers via a check valve. The check valve allows the flow of hydraulic oil from the piston rod side pressure chamber toward the pressure chamber on the opposite side of the piston rod and prevents its reverse flow. Therefore, when the damper 10 performs the extension operation, the flow path of the hydraulic oil from the piston rod side pressure chamber toward the pressure chamber on the opposite side of the piston rod becomes a path of the restriction hole and the communication path. On the other hand, when the damper 10 is contracted, the flow path of the hydraulic oil from the pressure chamber on the opposite side of the piston rod toward the pressure chamber on the piston rod side becomes a restriction hole only. Therefore, the damping force generated by the damper 10 during the stretching operation is smaller than the damping force generated during the contracting operation.

As shown in FIGS. 1 and 2, the pair of base portions 30A and 30B are connected to the first base portion 30A of the joint portion 15 connected to the bottom of the cylinder 11, and the joint to which the front end portion of the piston rod 13 is connected. The second base 30B of the portion 15. The first base portion 30A is placed on the upper surface of the furniture F, and the second base portion 30B is in contact with the ceiling C.

The outer diameter of the recess 35A is substantially equal to the inner diameter of the through hole 15A formed in the joint portion 15 of the damper 10. The outer diameter of the portion of the bushing 35 that rises from both ends of the recessed portion 35A is slightly larger than the inner diameter of the through hole 15A formed in the joint portion 15 of the damper 10. Further, the outer peripheral surface 35B of the both end portions of the bushing 35 is reduced in diameter in the outer direction. Therefore, the bushing 35 is inserted into the through hole 15A formed in the joint portion 15 of the damper 10 while being elastically deformed. Further, the bushing 35 is attached to the joint portion 15 of the damper 10 by fitting the recess 35A into the through hole 15A.

The inner diameter of the central portion of the bushing 35 is slightly larger than the outer diameter of the shaft portion 45B of the bolt 45. Further, the inner peripheral surface 35C of both end portions of the bushing 35 is expanded in the outward direction. Therefore, the bushing 35 is rotatable about the shaft portion 45B of the bolt 45. Further, the bushing 35 is inclined with respect to the shaft portion 45B of the bolt 45 so that the inner peripheral surface 35C of both end portions of the expanded diameter contacts the outer peripheral surface of the shaft portion 45B of the bolt 45. That is, the lining 35 is attached to the damper 10 of the joint portion 15, and is rotatably rotatable about the shaft portion 45B of the bolt 45, and is swayable in a direction crossing the rotation direction. Further, by elastically deforming the bushing 35, the damper 10 can be more swung in a direction crossing the direction of rotation.

As shown in FIGS. 1 to 4, the anti-slip portion 37 is slightly larger than the outer shape (rectangular shape) of the outer shape of the base body 31. The anti-slip portion 37 is made of rubber. Further, the anti-slip portion 37 is fitted into the first base portion 30A in a state of being placed on the upper surface of the furniture F, and is fitted to the lower end of the base body 31 to be opened.

As shown in Fig. 7, the anti-tip device includes a fixing cable 90 that holds the damper 10 in a contracted state of a desired length. The fixing cable 90 is a rope made of chemical fiber. The fixing cable 90 is fastened to the head portion 45A of the bolt 45 of the first base portion 30A and the second base portion 30B and the nut 47 in a state in which the damper 10 is contracted. In other words, the fixing cable 90 is fastened to the head portion 45A and the nut 47 of the bolt 45 of the first base portion 30A and the second base portion 30B on both sides, and is extended at the center portion.

Thus, the anti-tip device does not need to be provided with only the structure for stopping the fixing cable 90, and the damper 10 can be maintained at a desired length by the head 45A of the bolt 45 and the nut 47 located at both ends of the damper 10. The state of contraction. In addition, the anti-tip device can maintain the contraction length of the damper 10 by adjusting the length of the rope. Different contraction states. Therefore, even if the anti-tip device having the same length as the cylinder 11 and the piston rod 13 can correspond to the interval between the upper surface of the furniture F to be mounted and the ceiling C, it is prepared to maintain a plurality of types of shrinkage lengths of the damper 10 The state of contraction. Further, even if the specification of the length of the damper 10 is changed, it can be easily handled by changing the length of the fixing cable 90.

The anti-tip device is mounted on the upper surface of the furniture F and the ceiling C, and the first base portion 30A of the anti-tip device held in the contracted state by the fixing cable 90 abuts on the furniture F surface. Then, when the fixing cable 90 is disengaged or cut, the damper 10 is extended by the expansion force of the compressed gas enclosed in the cylinder 11, and the second base portion 30B is brought into contact with the ceiling C. Thus, since the operator does not need to perform the installation work of shrinking the damper 10 above the furniture F, the anti-tip device can be easily and safely mounted between the upper surface of the furniture F and the ceiling C.

Further, the anti-tip device can reduce the second base portion 30B by reducing the degree of elongation of the damper 10 when the state in which the fixing base 90 is contracted to the state in which the second base portion 30B abuts against the ceiling C is reduced. Abut the impact of the ceiling C. Therefore, a plurality of types of anti-tip devices having different lengths of the cylinder 11 and the piston rod 13 of the damper 10 can be prepared according to the interval between the upper surface of the furniture F and the ceiling C, and for the cylinder 11 and the piston rod 13 of the damper 10 For the same length, a plurality of types in which the contraction length of the damper 10 differs depending on the fixing cable 90 can be prepared.

Next, a method of attaching the anti-tip device to the upper surface of the furniture F and the ceiling C will be described. The furniture F is such that the back surface faces the wall surface W and is placed on the floor surface.

First, choose an anti-tip device, which is suitable for The length of the cylinder 11 and the piston rod 13 between the upper surface of the furniture F and the ceiling C of the anti-tip device is mounted, and the impact of the second base portion 30B against the ceiling C at the time of installation is reduced, and the fixing cable 90 is used.

That is, the drop preventing portion 50 is disposed between the wall surface W and the back surface of the furniture F. Further, in a state where the first base portion 30A is placed on the upper surface of the furniture F, the shaft portion 45B (rotational axis) of the bolt 45 of the first base portion 30A is inclined toward the furniture F due to shaking of an earthquake or the like. (Right direction in Fig. 8) extends in the direction orthogonal to each other. That is, the first base portion 30A is placed on the upper surface of the furniture F such that the direction in which the damper 10 rotates about the rotational axis is parallel to the oblique direction of the furniture F.

Then, the damper 10 is tilted such that the cylinder 11 of the damper 10 abuts against the support portion 71A of the angle restricting portion 70. In this state, the damper 10 has a suitable angle of inclination between 15° and 25°. Then, the direction of the second base portion 30B is aligned so that the shaft portion 45B (rotational axis) of the bolt 45 of the second base portion 30B is parallel to the shaft portion 45B (rotational axis) of the bolt 45 of the first base portion 30A.
