Description

The present invention relates to fixtures, a fall prevention device used thereto, and a base unit. Here, furniture such as cabinets and shelves (rack) is a typical example of furniture, but in addition, electric (electronic) products such as multifunction devices and refrigerators, display devices such as products, and fine arts are used. It includes a wide range of items that are placed on the floor, such as exhibition equipment, personal computer servers, and distribution boards, that may tip over in the event of an earthquake.

Many means have been proposed to prevent cabinets from tipping over in the event of an earthquake. There are two ways to prevent falls: one is to allow the cabinets to shake while mitigating the degree of shaking, and the other is to prevent the cabinets from moving independently even in the event of an earthquake (since the building moves during an earthquake, the cabinets). The idea is that the kind also sways with respect to the ground, but does not move relative to the building.)

As an example of the former method, as disclosed in Patent Document 1, there is a seismic isolation device that moves cabinets relative to the floor. On the other hand, as a means for preventing the cabinets from moving independently, as disclosed in Patent Document 2, a forward-facing fall prevention plate (outrigger) protruding in front of the cabinets is provided on the table on which the cabinets are placed. There is something. As a modification of Patent Document 2, Patent Document 3 discloses that a fall prevention plate is arranged inside an access floor.

Japanese Unexamined Patent Publication No. 2007-37990 Jitsufuku 4-24990 Gazette Japanese Patent No. 3541362

The means of Patent Document 1 is understood to be excellent in theory, but there is a problem that the structure becomes extremely complicated. Further, in the case of Patent Document 2, since the outriggers protrude greatly toward the front of the cabinet, there is a problem that people tend to trip over and the appearance deteriorates (even if covered with carpets, the height of the outriggers is high. Therefore, the problem has not been solved yet.) Further, if the fall prevention plate is built in the access floor as in Patent Document 3, the problems of tripping and aesthetics can be solved, but the problem that the construction takes a lot of time and the floor that is not the access floor cannot be applied and is versatile. There is a problem that it is inferior to.

By the way, regarding the layout of furniture placed on the floor, it is often the case that two furniture are arranged next to each other, for example, a pair of front and rear cabinets are arranged back to back. Adjacent fixtures are often firmly connected and integrated via a connector. As a result, the ground contact area becomes large as an integral body, so that the possibility of tipping over in the event of an earthquake is reduced to some extent.

However, since the two connected fixtures swing together, the amount of movement is large when the ground contact area becomes small due to the tilted posture due to the shaking of the earthquake, and it still falls without any measures. there's a possibility that. Further, when the means of Patent Documents 1 to 3 are applied to a plurality of fixtures, the above problem becomes more remarkable.

The invention of the present application was made in the wake of such a situation, and is applicable to fixtures arranged next to each other, and provides a fixture fall prevention technology having a simple structure, easy construction, and excellent practicality and versatility. It is intended to be provided.

The present invention includes a floor-mounted fixture, a fall prevention device and a base unit used therein, and a typical configuration thereof is specified in each claim of the claims.

The fall prevention device for fixtures of the present invention is a device installed between the floor and the fixtures to prevent the fixtures from tipping over, and includes a connecting portion in which a pair of fixtures arranged adjacent to each other are placed and connected. A swing allowance that allows the pair of fixtures to swing independently of each other along the direction in which the fixtures are lined up, and a swing suppression that suppresses the swing of the other fixture with the load of one fixture. It is equipped with a part.

According to the fall prevention device for furniture of the present invention, by swinging a pair of fixtures connected to the connecting portion independently of each other, the fixture is grounded when each of these fixtures swings and is in an inclined posture. Since there are two locations (one grounded portion of the fixture and the other grounded portion of the fixture), the amount of movement of these fixtures can be suppressed. Furthermore, when each pair of fixtures is in an inclined posture, the load of one fixture presses the swing suppressing portion downward to suppress the swing of the other fixture connected to the connecting portion, thereby suppressing the swing of the fixture. Can prevent the fall. In addition, construction is easy because it does not have to be fixed to the floor or wall. In addition, since the connecting portion can be constructed so as not to protrude to the outside of the fixture, it is possible to prevent deterioration of aesthetics and prevention of people's stumbling.

Is composed of a first swing permissible portion formed of a peripheral portion of the first connecting portion of the first plate-shaped member and a second peripheral portion of the second plate-shaped member formed of the peripheral portion of the second connecting portion. It may be composed of a swing allowance portion.

According to such an aspect, since the fall prevention device is composed of the first plate-shaped member and the second plate-shaped member separated from each other, the pair of fixtures can be reliably swung independently of each other with a simple structure. It will be possible. Further, when the first fixture swings (tilts) toward the second fixture, the first overhanging portion of the first plate-shaped member protruding toward the second fixture limits the swing, while the first fixture swings (tilts) to the second fixture. When swinging to the opposite side of the fixture, the first overhanging portion of the first plate-shaped member is caught in the lower part of the second fixture to limit the swing, so that the fall suppressing effect is high. For the second fixture, the second plate-like member functions similarly. Therefore, the fall prevention device of this aspect can swing a pair of fixtures independently of each other with a simple structure composed of two plate-shaped members, and can realize a fall prevention device for fixtures at low cost and easy to install. ..

Further, the swing allowance portion may be provided with a connecting tool for connecting the first fixture and the second fixture so as to be relatively vertically movable.

According to such an aspect, the first and second fixtures can be swung independently of each other while preventing the first and second fixtures from separating, and the fixtures can be more reliably prevented from tipping over. ..

Further, in the fall prevention device for furniture of the present invention, the connecting portion and the swing suppressing portion are formed on a plate-shaped member arranged below the pair of fixtures, and the connecting portion is formed by the above-mentioned connecting portion. Each of the pair of fixtures is provided at a portion of the plate-shaped member located below the fixture, and the swing suppressing portion is composed of a portion of the plate-shaped member that straddles the portion below the pair of fixtures and swings. The permissible portion may allow the fixture to swing by a vertical movement permissible portion that holds the fixture so that it can move up and down with respect to the connecting portion.

(1). Outline of First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. First, the first embodiment shown in FIGS. 1 to 9 will be described. This embodiment is applied to prevent a fall in a configuration in which steel cabinets 1 formed in a horizontally long rectangular shape in a plan view are arranged back to back in front and behind.

The cabinet 1 includes a cabinet main body 2 that opens forward, a horizontally rotatable double door 3 that opens and closes the opening, and a steel plate base 4 on which the cabinet main body 2 is placed. Since the depth of the cabinet 1 is much smaller than the height, it is easy to fall to the front or the back in the event of an earthquake. Therefore, the fall prevention device 6 is used.

The fall prevention device 6 is installed between the floor surface F and the pair of front and rear cabinets 1 to prevent the cabinet 1 from falling. The fall prevention device 6 allows the connecting portions 33 on which the cabinets 1 arranged adjacent to each other are placed and connected, and the cabinets 1 to swing independently of each other along the direction in which the cabinets 1 are lined up when shaking. It is provided with a swing allowing portion 39 to be allowed to swing, and a swing suppressing portion 73 to suppress the swing of the other cabinet 1 by the load of one cabinet 1.

The connecting portion 33, the swing suppressing portion 73, and the swing allowing portion 39 are formed on a plate-shaped member 7 arranged below the pair of front and rear cabinets 1. The plate-shaped member 7 is made of, for example, a steel plate. The connecting portion 33 is provided for each pair of front and rear cabinets 1 at a portion of the plate-shaped member 7 located below the cabinet 1. In the present embodiment, the plate-shaped member 7 is provided with two connecting portions 33 for one cabinet 1. That is, the plate-shaped member 7 is provided with a total of four connecting portions 33. In the present embodiment, the plate-shaped member 7 is placed on the floor surface F without being fixed.

The connecting portion 33 is made of a steel plate and is composed of horizontally long metal fittings on the left and right sides, is fixed to the plate-shaped member 7 by welding, and is connected to two places on the left and right of the rear portion of the base 4 constituting the lower part of the cabinet 1. That is, two of the four connecting portions 33 are arranged side by side in the front-rear direction at the front-rear center position of the portion of the plate-shaped member 7 near the left-right edge portion.

For example, as shown in FIGS. 6 and 8, an inverted M-shaped connecting member 22 connected to a rear portion of the base 4 is fixed to the connecting portion 33 with a bolt 25. Therefore, the connecting portion 33 has a tap hole 35 for fixing the connecting member 22. The connecting portion 33 may be formed of a tap hole formed in the plate-shaped member 7 without using a metal fitting for fixing.

As shown in FIG. 2, the swing suppressing portion 73 is composed of a portion of a plate-shaped member 7 straddling the lower part of the pair of front and rear cabinets 1. The plate-shaped member 7 includes a swing suppressing portion 73 arranged below the pair of front and rear cabinets 1, and a first slit 71 formed between the swing suppressing portion 73 and the connecting portion 33. A second slit 72 that separates the connecting portion 33 to which the cabinet 1 of the above cabinet 1 is connected and the connecting portion 33 to which the other cabinet 1 is connected is provided.

The rocking suppressing portion 73 is provided at the central portion of the plate-shaped member 7 so as to extend in the front-rear direction. The first slit 71 is a slit for separating the swing suppressing portion 73 and the connecting portion 33, is provided in pairs on the left and right with the swing suppressing portion 73 interposed therebetween, and is formed so as to extend in the front-rear direction. The second slit 72 is for separating the connecting portion 33 to which one cabinet 1 is connected and the connecting portion 33 to which the other cabinet 1 is connected, and is a central portion of the left and right edge portions of the plate-shaped member 7. It is formed so as to extend in the left-right direction through between the two front-rear connecting portions 33, and is connected to the front-rear central portion of the first slit 71. The second slits 72 are provided in pairs on the left and right. The swing permissible portion 39 is composed of a peripheral portion of the connecting portion 33 of the plate-shaped member 7.

In the present embodiment, the first slit 71 and the second slit 72 are formed in a substantially T shape, and the portion of the plate-shaped member 7 to which the two connecting portions 33 arranged in the front-rear direction are fixed is separated and shaken back and forth. It is also separated from the motion suppressing portion 73, and the swing allowing portion 39 is formed by providing a deformation allowance with respect to the swing suppressing portion 73 at a peripheral portion of the connecting portion 33 of the plate-shaped member 7. As a result, in the plate-shaped member 7, when an upward or downward force is applied to the connecting portion 33 due to the shaking of the cabinet 1 during the shaking of the earthquake, the connecting portion 33 and the swing allowing portion 39 move to the swing suppressing portion 73. It is configured to be deformable so that it can be displaced up and down with respect to.

As shown in FIG. 3, the fall prevention device 6 has a size that substantially overlaps with the pair of front and rear cabinets 1 in which the plate-shaped members 7 are arranged so as to face each other in a plan view, and both the front and rear edges and the left and right edges are cabinets. It does not protrude to the outside of 1 (outside of base 4). In the present embodiment, the front and rear edge portions of the plate-shaped member 7 are located on the front and rear inner sides of the front portion of the cabinet 1. The left and right edge portions of the plate-shaped member 7 are provided so as to be located at the same position as the left and right edge portions of the cabinet 1, or located on the left and right inside of the left and right edge portions of the cabinet 1.

As shown in FIGS. 2 and 6, the connecting portion 33 is formed with a protruding portion 33a protruding toward the front-rear center side of the plate-shaped member 7. The protrusion 33a is provided to stably mount the adjuster bolt 23. That is, in order to stably support the cabinet 1, it is preferable that the adjuster bolt 23 is arranged as close to the outer periphery of the base 4 as possible, and the adjuster bolt 23 is stably supported while making the area of the connecting portion 33 as small as possible. Therefore, a protrusion 33a is provided. The planar shape of the connecting portion 33 is not limited to this, and may be, for example, a substantially quadrangle.

Further, in the present embodiment, the connecting portion 33 is provided with a pair of front and rear tap holes 35, and the connecting member 22 is provided with front and rear bolt insertion holes 31 corresponding to the positions of the tap holes 35. Either tap hole 35 may be used when connecting the connecting member 22 to the connecting portion 33 with a bolt 25. For example, as shown in FIG. 7, the connecting portion 33 may be provided with one tap hole 35 on each side, or the connecting member 22 may be provided with one bolt insertion hole 31 on each side. May be good.

As shown in FIG. 8, the left and right adjuster bolts 23 that support the lower rear portion of the cabinet 1 are inserted from below into the upward bulging portion of the connecting member 22. From a different point of view, an upward bulging portion is formed on the connecting member 22 in order to form a space for arranging the head of the adjuster bolt 23. The rear portion of the base 4 is inseparably connected to the connecting portion 33 fixed to the plate-shaped member 7 via the connecting member 22 and the adjuster bolt 23. By rotating the adjuster bolt 23, the height of the rear portion of the base 4 can be adjusted.

Further, the front portion of the base 4 is placed on the front and rear edge portion of the plate-shaped member 7 via the left and right adjuster bolts 23. By rotating these adjuster bolts 23, the height of the front portion of the base 4 can be adjusted.

A spring washer or a rubber ring that overlaps the seat surface of the adjuster bolt 23 is fitted so that the head of the adjuster bolt 23 does not rattle between the connecting portion 33 and the connecting member 22 when the earthquake shakes. It is also possible to keep it in.

In the present embodiment, the front and rear edge portions of the plate-shaped member 7 are formed with cut-out portions 36 that are open in the front-rear and outward directions. The cut-out portion 36 is formed in the left and right intermediate portions, but it can also be formed in a plurality of left and right portions. The depth (depth) of the cut-out portion 36 is about one sixth of the front-rear length dimension of the plate-shaped member 7, but the left-right width and the depth can be arbitrarily set.

When the cut-out portion 36 is formed, the cable drawn from the inside of the double floor can be pulled out to the inside of the cabinet 1 without being exposed to the outside. Further, since the plate-shaped member 7 is easily twisted and deformed, there is an advantage that the plate-shaped member 7 can be prevented from being damaged. As shown in FIG. 2, the cables can be pulled out by replacing or in addition to the cut-out portion 36 with a circular window hole 38. A plurality of window holes 38 can be formed on the left and right sides, and the plate-shaped member 7 can be formed at a position near the center of the front and rear, for each of the front and rear cabinets 1, or below the front and rear cabinets 1. It is also possible to form.

(2). Details of the base unit As shown in FIGS. 1 and 3, the basic structure of the base 4 is the same as that of the conventional one, and the left and right side frames 16 and the front frame 17 and the rear frame 18 connecting them are connected. And have. Each frame 16, 17, 18 is formed in a groove shape having upper and lower horizontal pieces 19, 20 and vertical pieces 19a, 20a provided at the tips thereof.

The lower horizontal piece 20 is narrower than the upper horizontal piece 19. Further, although the upper horizontal piece 19 of the front frame 17 is wider than the upper horizontal piece 19 of the rear frame 18, both may have the same width.

Auxiliary frames 21 extending in the front-rear direction are arranged on the left and right sides of the base 4. The auxiliary frame 21 has a U-shaped shape that opens upward, and both front and rear ends are fixed to the front frame 17 and the rear frame 18 by welding or the like.

As will be shown in FIGS. 5 and 8, the lower end of the auxiliary frame 21 is located above the lower end of the base 4. The left and right longitudinal connecting members 22 are connected to the rear end of the auxiliary frame 21 by the adjuster bolts 23 via the nut cylinder 32. On the other hand, the adjuster bolt 23 is connected to the front end of the auxiliary frame 21 via a nut cylinder 32.

The lower surface of the connecting member 22 connected to the rear end of the auxiliary frame 21 is fixed to the connecting portion 33 of the fall prevention device 6 with bolts 25. The connecting member 22 has a substantially M-shaped front view having flap portions protruding from the left and right sides of the auxiliary frame 21, and the left and right flap portions are fixed to the metal fittings constituting the connecting portion 33 with bolts 25. The connecting member 22 is made of a steel plate thinner than the material plate of the base 4, and has rigidity to be deformed (elastic deformation and plastic deformation) when the cabinet 1 is shaken during an earthquake.

It is also possible to directly fix the auxiliary frame 21 to the connecting portion 33 without using the adjuster bolt 23 and the connecting member 22 for the connecting portion 33. Further, the adjuster bolt 23 and the connecting member 22 can be connected to the lower horizontal piece 20 of the base 4, and the lower horizontal piece 20 of the base 4 can be fixed to the connecting portion 33.

(3). Summary of the first embodiment Figure 1 shows an example of the construction procedure. First, the fall prevention device 6 is arranged at a predetermined position. Next, the cabinet 1 is placed on the plate-shaped member 7. In this case, the base 4 is first placed on the plate-shaped member 7, and then the cabinet body 2 is fitted into the base 4. As shown in FIG. 8, the cabinet body 2 has a bottom plate 2a, and the bottom plate 2a is provided with a downward piece 2c that enters the inside of the base 4. In the cabinet body 2, the downward piece 2c is fitted into the base 4, and the bottom plate 2a is fixed to the base 4 with screws.

FIG. 9 shows the swinging motion of the cabinet 1 before and after an earthquake and the deformation mode of the plate-shaped member 7. The front and rear cabinets 1 connected to the plate-shaped member 7 of the fall prevention device 6 independently sway in the front-rear direction due to the sway of the floor surface F. For example, as shown in FIG. 9, when the floor surface F moves to the right side of the paper due to the shaking of the earthquake, one cabinet 1 (the cabinet on the left side in FIG. 9) is in a forward leaning posture, and the other cabinet 1 is in a backward leaning posture. become.

When one of the cabinets 1 is in the forward leaning posture, it rotates forward with the lower front part of the cabinet 1 (the adjuster bolt 23 on the front side or the front frame 17 of the base 4) as a fulcrum. As described above, in the cabinet 1, the lower rear portion is connected to the connecting portion 33 of the fall prevention device 6, and the plate-shaped member 7 swings with the swing allowing portion 39 provided with the connecting portion 33. Since the first slit 71 is formed between the restraining portion 73 and the restraining portion 73, the connecting portion 33 and the swing allowing portion 39 to which the forward-rotating cabinet 1 is connected are lifted with respect to the swing suppressing portion 73. The plate-shaped member 7 is deformed.

Further, when the other cabinet 1 is in the backward tilted posture, the rear portion of the base 4 is fixed to the connecting portion 33, and the front portion of the base 4 is not fixed to the plate-shaped member 7, so that the cabinet 1 is not fixed. It rotates backward with the lower rear portion (connecting portion 33 or the rear frame 18 of the base 4) as a fulcrum. At this time, the constituent members (for example, the connecting member 22) of the rear portion of the base 4 are deformed, and the cabinet 1 is allowed to rotate backward. The rear frame 18 of the base 4 of the cabinet 1 in the backward tilted posture urges the swing suppressing portion 73 downward.

That is, the front and rear cabinets 1 connected to the fall prevention device 6 have two grounding points (the front lower part of one cabinet 1 and the other cabinet 1) when the cabinets 1 are tilted due to the shaking of the earthquake. (Lower back of). By the way, in the technique of firmly connecting the front and rear cabinets and swinging them integrally, the front and rear cabinets are integrally tilted, and there is only one grounding point. Therefore, the fall prevention device 6 provides friction between the cabinet 1 and the floor surface F (in the present embodiment, between the plate-shaped member 7 and the floor surface F) when the cabinet 1 is in an inclined posture during the shaking of an earthquake. Friction) can be increased as compared with the above technique, and the amount of movement of the cabinet 1 can be reduced.

Further, the plate-shaped member 7 is deformed (elastic deformation, plastic deformation, or both) so that the connecting portion 33 and the swing allowing portion 39 to which the forward-rotating cabinet 1 is connected are lifted with respect to the swing suppressing portion 73. As a result, the shaking of the cabinet 1 can be absorbed. Further, since the swing suppressing portion 73 of the plate-shaped member 7 is pressed downward by the load of the cabinet 1 (the cabinet on the right side in FIG. 9) which has been tilted backward due to the shaking of the earthquake, the plate-shaped member 7 is lifted. It is suppressed. As a result, the forward rotation of the cabinet 1 (the cabinet on the left side in FIG. 9) in the forward leaning posture can be restricted.

Further, the portion of the plate-shaped member 7 located below the one cabinet 1 (the portion near the front-rear end of the plate-shaped member 7 and the swing suppressing portion 73) projects rearward with respect to the other cabinet 1. Therefore, the backward rotation of the cabinet 1 is suppressed. In this way, the fall prevention device 6 can absorb and suppress the swing of the cabinet 1, so that the fall of the cabinet 1 can be prevented.

Further, the fall prevention device 6 does not have to be fixed to the floor or wall, so that the construction is easy. Further, since the plate-shaped member 7 can be configured so as not to protrude to the outside of the pair of front and rear cabinets 1, it is possible to prevent deterioration of aesthetics and prevention of people from stumbling. As described above, the fall prevention device 6 can swing the pair of cabinets 1 independently of each other with a simple structure, and can realize a structure that is low in cost and easy to install.

In the fall prevention device 6 of the present embodiment, the lower rear portion of the cabinet 1 is connected to the plate-shaped member 7 by the connecting member 22 and the connecting portion 33, but the lower front portion of the cabinet 1 is also the same as the lower rear portion. In addition, the connecting member 22 and the connecting portion 33 may be connected to the plate-shaped member 7. In this case, the leading edge portion of the plate-shaped member 7 is lifted when the cabinet 1 is rotated backward due to the shaking of the earthquake, but the swing suppressing portion 73 is bent and deformed to secure the grounding of the cabinet 1 in the backward tilting posture. can.

(4). Second to Third Embodiments FIG. 10 shows other embodiments. In the second embodiment shown in FIG. 10A, the fall prevention devices 6 corresponding to the front and rear cabinets 1 arranged so as to face each other are separated to the left and right. Adopting the separation method in this way has an advantage that one type of fall prevention device 6 can handle furniture having different widths. Further, the second embodiment has an advantage that the area of the plate-shaped member 7 can be reduced, so that the manufacturing cost can be reduced and the plate-shaped member 7 can be easily transported and stored. Further, when the separation method is adopted as in the present embodiment, a part of the bottom portion of the cabinet 1 (the portion not facing the plate-shaped member 7) faces the floor surface F, so that the cabinet 1 is pulled out from the inside of the double floor. The cable can be easily pulled out inside the cabinet 1 without being exposed to the outside.

In the third embodiment shown in FIG. 10B, the left and right first slits 71 are formed on the plate-shaped member 7 with the front and rear connecting portions 33 interposed therebetween, and the swing suppressing portions 73 are also formed on the left and right outer sides of the first slit 71. Is forming.

The elastic member 44 may be made of any material or shape as long as the cabinet 1 (connecting member 22) can be urged downward at least when the cabinet 1 is in an inclined posture. For example, a rubber washer may be used. good. Further, the arrangement configuration of the elastic member 44 is not limited to the configuration in which the shaft portion of the bolt 43 is inserted, and the cabinet 1 is placed at least when the cabinet 1 is in an inclined posture, for example, when the elastic member 44 is arranged at a position away from the bolt 43. Any configuration may be used as long as it can be urged downward.

In the present embodiment, the swing allowing portion allows the cabinet 1 to swing by the vertical movement allowing portion 45 that holds the cabinet 1 so as to be vertically movable with respect to the connecting portion 33. As described above, the vertical movement allowable portion 45 is composed of bolts 43 provided on the connecting portion 33 that supports the lower rear portion of the cabinet 1. The front and rear cabinets 1 are respectively connected to the plate-shaped member 7 by bolts 42 at the front lower portion and vertically movable to the plate-shaped member 7 by bolts 43 at the rear lower portion. Further, each of the left and right plate-shaped members 7 arranged below the pair of front and rear cabinets 1 constitutes a swing suppressing portion that suppresses the swing of the other cabinet 1 by the load of one cabinet 1. There is.

That is, the connecting portion 33 and the swing suppressing portion of the fall prevention device 6 of the present embodiment are formed on the plate-shaped member 7 arranged so as to straddle the lower side of the pair of cabinets 1. The connecting portion 33 is provided for each pair of front and rear cabinets 1 at a portion of the plate-shaped member 7 located below the cabinet 1. Further, the swing suppressing portion is composed of a portion of a plate-shaped member 7 (in the present embodiment, the entire plate-shaped member 7) straddling the lower part of the pair of front and rear cabinets 1. Further, at least the elastic member 44 that urges the connecting member 22 downward when the cabinet 1 rotates forward also constitutes the swing suppressing portion. The vertical movement allowable portion 45 constituting the swing allowable portion holds the cabinet 1 so as to be vertically movable with respect to the connecting portion 33. The plate-shaped member 7 of the seventh embodiment is composed of a plate thickness (thickness) that is less likely to be deformed (elastic deformation and plastic deformation) than the plate-shaped member 7 of the first to sixth embodiments described above. There is. However, the thickness of the plate-shaped member 7 in the seventh embodiment is not particularly limited, and may be the same as or thinner than the thickness of the plate-shaped member 7 in the first to sixth embodiments. ..

FIG. 23 shows the swaying movement of the cabinet 1 before and after an earthquake. The front and rear cabinets 1 connected to the plate-shaped member 7 of the fall prevention device 6 independently sway in the front-rear direction due to the sway of the floor surface F. For example, as shown in FIG. 23, when the floor surface F moves to the right side of the paper due to the shaking of the earthquake, one cabinet 1 (the cabinet on the left side in FIG. 23) is in a forward leaning posture, while the other cabinet 1 (FIG. 23). Then, the cabinet on the right side) hardly tilts to the rear side (it becomes a little backward leaning posture).

When the cabinet 1 rotates forward with its front lower portion as a fulcrum, the elastic member 44 is compressed and deformed so that the rear connecting member 22 that can move up and down is lifted from the plate-shaped member 7 and is in a forward leaning posture. obtain. Here, since the upward movable range of the connecting member 22 on the rear side is regulated by the bolt 43 and the elastic member 44, the cabinet 1 is prevented from tipping forward.

When one cabinet 1 rotates forward, the other cabinet 1 is in a state of urging the plate-shaped member 7 downward. That is, the front and rear cabinets 1 connected to the fall prevention device 6 of the present embodiment have two grounding points (in front of one cabinet 1) when one of them is in an inclined posture due to the shaking of an earthquake. The lower part and the lower part of the other cabinet 1). Therefore, the fall prevention device 6 can increase the friction between the cabinet 1 and the floor surface F (friction between the plate-shaped member 7 and the floor surface F) when the cabinet 1 shakes, and the cabinet 1 moves. The amount can be reduced.

Further, when the cabinet 1 is in the forward leaning posture, the elastic member 44 between the connecting member 22 on the rear side and the head of the bolt 43 is compressively deformed, so that the shaking of the cabinet 1 can be absorbed. Further, the forward rotation of the cabinet 1 in the forward leaning posture is restricted by the plate-shaped member 7 being pressed downward by the load of the other cabinet 1. Further, since the portion of the plate-shaped member 7 located below the one cabinet 1 projects rearward with respect to the other cabinet 1, the backward rotation of the cabinet 1 is suppressed. In this way, the fall prevention device 6 can absorb and suppress the swing of the cabinet 1, so that the fall of the cabinet 1 can be prevented.

Further, the fall prevention device 6 of the present embodiment does not have to be fixed to the floor or wall, so that the construction is easy.

The shaking of 1 can be absorbed more effectively. Further, when the cabinet 1 is in the backward tilted posture, the vibration of the cabinet 1 can be absorbed by the compressive deformation of the elastic member 44. Further, in the eighth embodiment, the connecting member 22 is fixed to the connecting portion 33 by the bolt 25 by compressing and deforming the elastic member 44 even when the cabinet 1 swings in either the front-back direction (FIG. 4). Etc.), the deformation of the connecting member 22 can be reduced, and the durability is improved.

The vertical movement allowable portion 45 composed of the bolt 43 can be applied to any of the above-mentioned second to sixth embodiments. Further, the swing suppressing portion composed of the elastic member 44 can also be applied to any of the above-mentioned second to sixth embodiments. For example, in the fourth embodiment (see FIGS. 11 to 15) in which the plate-shaped member is divided into the first plate-shaped member 7A and the second plate-shaped member 7B as in the ninth embodiment shown in FIG. 25. The cabinet 1 (connecting member 22) and the connecting portion 33 (metal fittings) may be connected by the bolt 43 constituting the vertical movement allowable portion 45, or a swing suppressing portion composed of the elastic member 44 may be provided. good.

Further, as in the tenth embodiment shown in FIGS. 26 and 27, the front and rear end portions 12 of the plate-shaped member 7 located below the front lower portion of the front and rear cabinet 1 are separated from the floor surface F toward the front end side. It may be inclined upward so as to be. Here, the front and rear end portions 12 are both end portions of the plate-shaped member 7 in the direction in which the front and rear cabinets 1 are arranged (front and rear direction), and extend in the left and right direction.

According to the present embodiment, when the cabinet and the fall prevention device 6 move due to the shaking of an earthquake or the like, the front and rear end portions 12 of the plate-shaped member 7 are prevented from being caught on the floor surface F, and the cabinet 1 swings (tilts). ) Can be suppressed, and the cabinet 1 can be prevented from tipping over more reliably. This embodiment is particularly effective when the floor surface F is made of a flexible and highly frictional material such as a carpet.

Further, the left and right end portions of the plate-shaped member 7 may also be configured to be inclined upward so as to be separated from the floor surface F toward the tip end side, similarly to the end portion 12. As a result, when the cabinet 1 and the fall prevention device 6 move in the left-right direction, it is possible to prevent the left and right ends of the plate-shaped member 7 from being caught on the floor surface F, and the inclination of the cabinet 1 in the left-right direction is suppressed. , The fall of the cabinet 1 can be prevented more reliably. The configuration in which at least one of the front and rear end portions 12 and the left and right end portions of the plate-shaped member 7 is inclined upward so as to be separated from the floor surface F toward the tip end side is the above-described first to ninth embodiments.
