Description

  The present invention relates to a technique for preventing stored furniture from falling down due to an earthquake or the like.

  Conventionally, in order to prevent the storage furniture from overturning, a support rod for height adjustment protrudes upward from the top plate of the storage furniture, and a projecting body provided on the upper end of the support rod by adjusting the protrusion length of the support rod has been provided. Japanese Patent Application Laid-Open No. H10-228561 is known that abuts against the ceiling surface so that the storage furniture does not fall down during an earthquake.

  In such a thing that prevents the storage furniture from toppling by abutting the upper end of the supporting rod against the ceiling surface, the larger the area of the protruding body that abuts the ceiling surface, the more effectively the ceiling surface is not damaged. growing.

  FIG. 11A shows a schematic diagram of the above-described conventional example at the normal time. However, when the storage furniture 1 is tilted at the time of an earthquake, if the area of the projecting body 5 ′ in contact with the ceiling surface 6 is large, the support rod 20 is tilted following the tilt of the storage furniture 1, and the rear end of the projecting body 5 ′. Only in the state where only the storage furniture 1 is in contact with the storage furniture 1, the tension body 5 ′ tends to incline. For this reason, stress concentrates on the part indicated by A in FIG. There is a problem of doing.

  Also, Patent Document 2 discloses that a projecting body having a large area is supported by a plurality of screw rods and abuts against the ceiling surface. However, in this conventional example, the projecting body and the plurality of screw rods are connected. Therefore, it is difficult to work alone by rotating a plurality of screw rods and pushing the tension body upward by supporting the tension body with a large area by hand. Therefore, there is a problem that a plurality of workers must work.

In any of the conventional examples described above, when the storage furniture sinks, the struts that are in contact with the ceiling surface fall downward from the ceiling surface, and in this case, the storage furniture cannot be prevented from falling. There is a problem.
Japanese Utility Model Publication No. 5-72234 JP 2006-158809 A

  The present invention has been invented in view of the above-described conventional problems, and can stabilize the abutting state of the tension member to the ceiling surface, and the mounting portion of the screw rod to the tension member can be damaged. Or the screw rod can be prevented from bending, and the furniture can be prevented from overturning by holding the state where the suspension body is in contact with the ceiling surface, and the suspension body can be prevented from falling over by contacting the suspension body to the ceiling surface. In addition, even if the storage furniture sinks downward, it can continue to contact the ceiling of the tension body, and the furniture can be prevented from falling down. It is a problem to provide.

  In order to solve the above-mentioned problems, the furniture overturn prevention structure according to the present invention includes a height-adjusting screw rod 3 having a projecting body 5 at the upper end from the upper surface of the storage furniture 1 and one or more supports. Each of the bars 4 is erected so that the protruding length can be adjusted upward, the protruding body 5 is brought into contact with the ceiling surface 6 by adjusting the protruding length of the screw bar 3, and the supporting bar is adjusted by adjusting the protruding length of the supporting bar 4. The upper end portion of 4 is in contact with the lower surface of the projecting body 5 in contact with the ceiling surface 6.

  With such a configuration, it is possible to maintain the state in which the tension body 5 is supported by the screw rod 3 and the support rod 4 and the tension body 5 is in contact with the ceiling surface 6. In supporting the tension member 5 with the screw rod 3 and the support rod 4, first, without supporting the tension member 5 by hand, the tension member 5 is simply adjusted by adjusting the protrusion length of the screw rod 3. After that, the support bar 4 is adjusted by adjusting the protruding length and the upper end portion of the support bar 4 is brought into contact with the lower surface of the projecting body 5 in contact with the ceiling surface 6 so that the operation is completed. Even one person can work easily and reliably.

  Moreover, it is preferable to attach the projecting body 5 to the upper end portion of the screw rod 3 so as to be rotatable with respect to the screw rod 3 and not to move in the vertical direction.

  With this configuration, the screw rod 3 is rotated to adjust the protruding length, and the projecting body 5 is applied to the ceiling surface 6, and the screw rod 3 is further rotated to hit the ceiling surface 6. It is possible to strongly press the projecting body 5 against the ceiling surface 6. In this case, when the projecting body 5 is in contact with the ceiling surface 6, the projecting body 5 is strongly pressed against the ceiling surface 6 without rotating. It is not damaged by the rotation in the pressing state of 5. Further, the posture when the projecting body 5 hits the ceiling surface 6, that is, the screw rod 3 can be rotated while maintaining the initial contact posture, so that the projecting body 6 can be strongly pressed against the ceiling surface 6. If the position where the body 5 is pressed against the ceiling surface 6 by the support bar 4 at the initial stage is positioned so as to be directly above the support bar 4, the rotation of the screw bar 3 is completed. It is also possible to ensure that the upper end of the support bar 4 abuts on the target position of the tension member 5 in the subsequent step.

  Further, it is preferable that the projecting body 5 is fixed to the upper end portion of the screw rod 3.

  With such a configuration, it is possible to easily and reliably attach the tension member 5 to the upper end portion of the screw rod 3.

  Further, it is preferable that the screw rod 3 is attached to the central portion of the projecting body 5 and the support rod 4 is brought into contact with the lower surface of the projecting body 5 at a position shifted backward from the attaching portion of the screw rod 3.

  By adopting such a configuration, even if the area of the strut body 5 is large, the rear part of the strut body 5 can be struck by the strut body 5 following when the storage furniture 1 is tilted during an earthquake. Can be reinforced with the support rod 4 to prevent the projecting body 5 from being inclined, the mounting portion of the projecting body 5 at the tip of the screw rod 3 from being damaged, and the screw rod 3 from being bent. The storage furniture 1 can be prevented from falling.

  Moreover, it is preferable that the screw rod 3 and the support rod 4 are erected on the attachment member 7 fixed to the upper surface of the storage furniture 1 so that the protruding length can be adjusted upward.

  Thus, the screw rod 3 and the support rod 4 are erected on the attachment member 7, so that the top plate 2 can be reinforced by the attachment member 7, and the screw rod 3 and the support rod 4 are erected and the attachment member. Since 7 is attached to the top plate 2, the screw rod 3 and the support rod 4 can be easily attached to the upper surface of the storage furniture 1 so as to freely protrude upward.

  Moreover, it is preferable to include a spring 8 that urges the tension member 5 upward and a return prevention mechanism 9 that prevents the tension member 5 from returning downward.

  Since the projecting body 5 is biased upward by the spring 8 and does not return downward, even if the storage furniture 1 sinks downward, the contact state of the projecting body 5 to the ceiling surface 6 is maintained. The storage furniture 1 can be reliably prevented from falling over.

  Further, the top plate 2 is installed between the upper end portions of the inner surfaces of the opposing side plates 21 to constitute the storage furniture 1 in which the upper end surface of the side plate 21 and the upper surface of the top plate 2 are flush with each other. Are arranged side by side so that the side plates 21 come into contact with each other, and the mounting member 7 is connected to the other top plate through the upper end surface of one side plate 21 and the upper end surface of the other adjacent side plate 21 from the upper end of one top plate 2. It is preferable to adhere to both storage furniture 1 in the state mounted over the upper surface edge part of the board 2.

  With such a configuration, the load applied to the storage furniture 1 from the brace 5 during an earthquake is directly supported by the two side plates 21 that are in contact with each other of the storage furniture 1 adjacent to the mounting member 7. Therefore, it is possible to prevent a phenomenon in which the load is concentrated on the top plate 2 and the joint at the joint portion between the side end surface of the top plate 2 and the inner surface of the side plate 21 is disengaged, and the storage furniture 1 can be overturned during an earthquake. The strut 5 can reliably prevent this. Furthermore, since the attachment member 7 is fixed to the two storage furniture 1, the position of the tension body 5 does not occur, and there is no fear that it will be detached from the storage furniture 1 due to vibrations in the event of an earthquake. Can be prevented from falling.

  According to the first aspect of the present invention, the projecting body provided at the upper end of the screw rod contacts the ceiling surface, and the upper end of the support rod contacts the lower surface of the projecting body contacting the ceiling surface. The rod and the support rod can stabilize the abutment on the ceiling surface, and the screw rod and the support rod can support the projecting body, but the screw rod and the support rod By performing the adjustment, it is possible to make contact with the ceiling surface without holding the tension body by hand, and the support bar only needs to be adjusted to project upward thereafter, so that one person can work easily and reliably.

  In addition to the effect of the invention described in claim 1, the invention described in claim 2 is configured so that the projecting body is rotatable relative to the screw rod at the upper end of the screw rod and does not move in the vertical direction. Since it is attached, the strut can be strongly pressed against the ceiling surface without damaging the ceiling surface.

  Moreover, in addition to the effect of the invention described in the first aspect, the invention described in the third aspect can easily and reliably attach the tension body to the upper end portion of the screw rod.

  In addition, in the invention described in claim 4, in addition to the effect of the invention described in any one of claims 1 to 3, the screw rod is attached to the center portion of the tension member and the support rod is tensioned. Since it is abutted at a position shifted backward from the mounting part of the screw rod on the lower surface of the body, it is difficult to tilt the bracing body so as to be lowered forward, the mounting part of the bracing body to the screw rod is damaged, or the screw The stick can be prevented from bending, and the state where the strut is in contact with the ceiling surface can be securely held to prevent the storage furniture from falling.

  Further, in the invention described in claim 5, in addition to the effect of the invention described in any one of claims 1 to 4, the screw rod and the support are attached to the mounting member fixed to the upper surface of the storage furniture. Since the rods are erected so that the protruding length can be adjusted upward, the top plate can be reinforced and the screw rod and the support rod can be easily attached to the top plate.

  Further, in the invention described in claim 6, in addition to the effect of the invention described in any one of claims 1 to 5, a spring for urging the strut body upward, and a lower part of the strut body Since it has a return-preventing mechanism that prevents it from returning to the back, even if the storage furniture sinks downward, it can continue to make contact with the ceiling surface of the strut body, and the storage furniture can be reliably prevented from falling over. .

  In addition, in the invention according to claim 7, in addition to the effect of the invention according to claim 5, the mounting member is connected from the upper end of one top plate to the upper end surface of one side plate, and the other side plate adjacent to it. The two side plates of the storage furniture adjacent to the mounting member are loaded by the load on the storage furniture in the event of an earthquake. This prevents the phenomenon that the load is concentrated on the top plate and the joint at the joint between the side surface of the top plate and the inner surface of the side plate is disengaged. The mounting body is securely attached to both storage furniture, so that the position of the tension body does not shift and it is likely to come off from the storage furniture due to vibrations in the event of an earthquake. No, it is possible to prevent the fall of reliable storage furniture.
