Description

  The present invention relates to a fall-preventing furniture, and more particularly, to a fall-preventing furniture that does not cause a fall when a furniture body in which a plurality of independent storage units are stacked is shaken by an earthquake or the like.

  In general, a book shelf, an organized cupboard or rack (hereinafter, referred to as “furniture”) and the like for storing various articles are often placed in the room of a building. Such furniture is fixed to the building using a fall prevention device to prevent the fall due to the shaking at the time of an earthquake. Such a fall-preventing instrument or structure is already well known as described in Patent Document 1 or Patent Document 2. Patent Document 1 discloses an invention of a seismic structure for furniture and seismic furniture, and Patent Document 2 discloses a device for a stretcher. The inventions and devices described in these Patent Documents 1 and 2 are mainly used in the case of furniture made in one piece, or in the case of furniture in which the upper storage portion is stacked on the lower storage portion. The present invention is applied to furniture that is integrally connected by an appropriate connector, and is unsuitable for furniture that is configured by simply stacking individual storage portions.

That is, the earthquake-proof structure for furniture described in Patent Document 1 is a gate-shaped structure composed of opposing left and right side plates standing between a floor surface and a ceiling surface, and a top plate connecting the upper portions of these two left and right side plates. It is a structure, and furniture is housed in this portal structure to prevent falls caused by shaking such as an earthquake. Moreover, the projecting tool disclosed in Patent Document 2 has a base attached to both ends of a telescopic rod, and is placed and stretched between the upper surface of the furniture installed on the floor and the ceiling surface. By applying an acting force in the direction of pressing the furniture against the floor surface, it is intended to resist shaking during an earthquake, thereby preventing falls.
JP 2005-152512 A Registered Utility Model No. 3021136

  However, in furniture in which individual storage units are stacked in an unconnected state, even if the furniture is housed in the earthquake-resistant structure having a portal structure disclosed in Patent Document 1, the shaking at the time of an earthquake is individually Propagation to the storage unit causes a shift in the upper and lower storage units as if the drawer of the chiffon pops out. As a result of the increase of the shift due to repeated shaking, the stacking of each storage unit collapses and falls. In addition, even when the inventive stretching tool disclosed in Patent Document 2 is used, in the furniture in which a plurality of storage portions are stacked in an unconnected state, each of the furniture positioned between the uppermost and lowermost stages as described above is used. The movement of the storage unit cannot be completely controlled, and if a large shake occurs during an earthquake, the stacked storage unit collapses and falls. For this reason, it has been desired to develop a means for preventing furniture from simply falling down due to shaking during an earthquake, etc., for furniture that is simply stacked in a plurality of independent storage units.

  The object of the present invention was made to solve such a conventional problem, and when a furniture body in which a plurality of individually independent storage portions are stacked so as to be able to move with respect to each other is subjected to shaking by an earthquake, An object of the present invention is to provide a fall-preventing furniture that absorbs the upper part of the furniture body without shaking and prevents the furniture body from falling.

  The present invention is a fall-preventing furniture that does not fall over in the event of an earthquake. The feature of the furniture is that the furniture body is formed by stacking a plurality of individually independent storage units from the floor surface of the room, and stacked. Each storage unit is configured with a support rod that prevents the storage unit from collapsing due to shaking during an earthquake, and the storage units of the furniture body are stacked in a non-connected state so as to be able to shift relative to each other. The top plate and the bottom plate are formed with an insertion opening through which the support rod can be installed between the floor surface and the ceiling surface above the furniture body through the interior of the furniture body. The opening formed in the top plate and the bottom plate of each storage unit is larger than the cross-sectional shape of the support bar, and the lower end of the support bar installed through the opening of each storage unit; The upper end is in contact with the floor surface and the ceiling surface, respectively. The housing portion is moved deviation by shaking overlaps the housing portion of the lower absorbing the vibration of the furniture body.

  As an example of the embodiment according to the fall-preventing furniture of the present invention, the opening can be formed by a circular or polygonal hole including an elliptical shape. Moreover, as another example of the embodiment according to the fall prevention furniture of the present invention, the storage unit includes a detachable partition shelf, and the support bar passes through the shelf in the shelf. A cutout portion cut from an edge of the shelf plate in the same direction as the direction in which the shelf plate is attached to and detached from the storage portion is formed, and the outside of the support rod positioned in the cutout portion is formed. A gap is formed between the periphery and the inner edge of the notch.

  Furthermore, as another example of the embodiment according to the fall prevention furniture of the present invention, the support bar is provided with a length adjustment mechanism at one or both of the upper end portion and the lower end portion thereof, and the floor It is a tension rod installed so as to stretch between a surface and the ceiling surface.

  Furthermore, as another example of the embodiment according to the fall prevention furniture of the present invention, either or both of the upper end portion and the lower end portion of the support bar are arranged on the floor on which the fall prevention furniture is arranged, or just above the floor. Is embedded in the ceiling.

  According to the fall-preventing furniture of the present invention, when the furniture body shakes during an earthquake, each storage part moves with respect to the lower storage part on which it is stacked, so that the shaking reaches the upper part of the furniture body. Is absorbed without. In other words, since each storage unit can move within a predetermined range by the support rod, it can reciprocate in the direction of shaking of the building without dropping from the lower storage unit. It is possible to prevent the shaking from spreading to the upper part of the furniture body. In general, when shaking caused by an earthquake continues, the furniture gradually amplifies, and as a result, the upper part of the furniture falls because it swings with a large amplitude. However, in the fall prevention furniture of this invention, since each storage part is shifted and moved positively, the swing acting on the furniture body is absorbed by the movement of each storage part and does not reach the top of the furniture body, As a result, the furniture body can be prevented from falling, and the life of the furniture body can be protected without damaging a person near the furniture body.

  Moreover, according to the fall-preventing furniture of the present invention, when the support bar is passed through the interior of each storage unit and stands between the floor surface and the ceiling surface, the opening formed in each storage unit includes an oval shape. Since it is a circular or polygonal hole, it does not require high-grade processing for each storage part used as fall prevention furniture, and it is only necessary to drill the holes of the shape described above in the top and bottom plates. There is no increase in manufacturing costs.

  Furthermore, according to the fall-preventing furniture of the present invention, when all or a part of the plurality of storage units stacked includes a detachable partition shelf, the shelf includes the storage unit. By providing a notch portion cut from the edge in the same direction as the direction of attaching and detaching the shelf, it is possible to attach the shelf plate even if the support bar is inserted through the inside of the storage portion. Moreover, when the shelf board is attached to the storage part, the notch part formed in the shelf board is formed with a size that opens a predetermined interval between the inner edge part and the outer peripheral surface of the support bar. Even in the storage section after the plate is attached, the storage section can be moved due to shaking during an earthquake and the swing acting on the furniture body can be absorbed, so that the furniture body can be prevented from falling.

  Furthermore, according to the fall prevention furniture of the present invention, if the length adjusting mechanism is attached to either the upper end portion or the lower end portion of the support rod, the support rod is stretched between the floor surface and the ceiling surface. It can be installed, so that it can sufficiently withstand the force acting on the support bar with the movement of each storage part due to shaking during an earthquake, and as a result, each stacked storage part can move The furniture body can be prevented from falling. In addition, it is also preferable that either one or both of the upper end portion and the lower end portion of the support bar are embedded in the floor or ceiling and firmly fixed.

  Hereinafter, the embodiment of the anti-falling furniture according to the present invention shown in the drawings will be described in more detail. FIG.1 and FIG.2 is the front view and side view which show the fall prevention furniture based on one Embodiment of this invention. The fall-preventing furniture 10A according to this embodiment passes through the interior of the furniture body 12 and the furniture body 12 in which storage boxes 11 as a plurality of independent storage sections are stacked from the indoor floor surface F. It is comprised from the support bar 13 stood between the floor surface F and the ceiling surface R located above the furniture main body 12. FIG. Each storage box 11 is configured by assembling opposing top and bottom plates 11a and 11b, opposing side plates 11c and 11d, and a back plate 11e into a box shape, and the front side facing the back plate 11e is opened, Various articles such as books and files are taken in and out from the opening. Such storage boxes 11 are stacked in an unconnected state and slidable with respect to each other. Since the stacked storage boxes 11 need to be able to shift (slide) with respect to the lower storage box 11, the top plate 11a and the bottom plate 11b are formed as flat plates, and in particular, the outer surfaces thereof are smooth. Is desirable. For this purpose, it is also preferable to attach or apply a material with high smoothness to the outer surface of the top plate 11a and the bottom plate 11b where the storage boxes 11 overlap. In this embodiment, the storage box 11 has a box shape that is open on the front side. However, the present invention is not limited to such a structure. For example, a door is attached to the opening on the front side. It may be.

  On the top plate 11 a and the bottom plate 11 b of each storage box 11, a support bar 13 passes between the interior of the furniture body 12 and stands between the floor surface F and the ceiling surface R located above the furniture body 12. An opening 16 for insertion (see FIG. 3) is formed. As apparent from FIG. 3, the opening 16 is larger than the cross-sectional shape of the support bar 13, and thus a gap 17 is formed between the inner peripheral edge of the opening 16 and the outer peripheral surface of the support bar 13. The presence of the gap 17 is a very important factor for the present invention. Therefore, when the support bar 13 is erected between the floor surface F and the ceiling surface R through the opening 16, the support bar 13 It is desirable that the opening 16 is located approximately at the center. In the fall prevention furniture 10A of this embodiment, the opening 16 is circular as shown in FIG. 3, but in the present invention, it is not necessary to be circular, and may be an elliptical or polygonal opening. . In short, as long as the gap 17 is formed between the inner peripheral edge of the opening 16 and the outer peripheral surface of the support bar 13 as described above, the shape and shape may be sufficient.

  Moreover, the opening 16 formed in the top plate 11a and the bottom plate 11b of each storage box 11 is formed at a position that overlaps in the height direction when the storage boxes 11 are stacked. The “position overlapping in the height direction” means that when the stacked storage boxes are viewed from directly above and vertically downward, all the openings 16 overlap and appear as one. More specifically, the positions, sizes, and shapes of the openings 16 in the stacked storage boxes 11 do not have to be the same, and the openings 16 in the storage boxes 11 are partial as described above. Need only be large enough to form a gap 17 with the support bar 13. As for the positional relationship between the opening 16 in each storage box 11 and the support rod 13 passing through the opening 16, each storage box 11 can obtain the maximum movable amount with respect to the storage box 11 immediately below it. Ideally. In addition, the position of the opening 16 formed in the top plate 11a and the bottom plate 11b of each storage box 11 is not an essential matter for the fall-preventing furniture 10A of the present invention. Instead, as long as the gap 17 is formed between the inner peripheral edge of the opening 16 and the outer peripheral surface of the support bar 13, it may be formed at any position in the outer surface area of the top plate 11a and the bottom plate 11b. However, for the purpose of storing books and files in each storage box 11, it is desirable that the opening 16 be formed closer to the back plate 11e than the center position of the top plate 11a and the bottom plate 11b.

  The height dimension of each storage box 11 is completely arbitrary, and in some cases, a partition shelf 18 may be detachably attached to each storage box 11 for use. In such a case, the shelf board 18 in which the notch part 19 was formed as shown in FIG. 3 is used. That is, the notch 19 formed in the shelf board 18 is cut inwardly from the insertion side end edge 18a to the storage box 11, and the inner peripheral edge thereof is substantially U-shaped. The cut-out depth L of the notch 19 formed in the shelf board 18 is set at a predetermined position by placing the shelf board 18 in the storage box 11 and placing it on the receiving metal 20 attached to the both side boards 11c and 11d. In the same manner as the openings 16 formed in the top plate 11a and the bottom plate 11b, the size is such that a gap is formed between the outer peripheral surface of the support bar 13 and the inner peripheral edge of the notch portion 19. The cut width S of the notch portion 19 allows passage of the support bar 13 when the shelf board 18 is inserted to a predetermined position inside the storage box 11, in other words, a path in which the support bar 13 does not interfere with the arrangement of the shelf board 18. The dimensions are as follows. Therefore, although not shown as such a notch portion 19, for example, a keyhole shape, that is, a cut width S of a part from the edge 18 a of the shelf board 18 to a predetermined length shorter than the cut depth L is illustrated. It is well understood from the above description that the width of the support rod 13 may be smaller than the width shown in FIG.

  As shown in FIG. 4, the support bar 13 includes a support tube main body 14 and a length adjusting mechanism 15 provided at both ends thereof. Such a support bar 13 is often used when a partition is installed in a room of a building, and is already known. However, to briefly explain an example thereof, the length adjusting mechanism unit 15 has a truncated portion. A conical base 15a and a threaded rod 15b projecting from the truncated head are mounted. The threaded rod 15b is screwed onto the internal threaded portion from the end surface of the support tube body 14, and then mounted. By adjusting the screwing amount of the threaded rod 15b, the overall length of the support rod 13 can be adjusted. Such a support bar 13 is generally called a tension bar or the like.

  Next, a method for assembling the fall-preventing furniture 10A according to this embodiment and a state when subjected to shaking due to an earthquake or the like will be described. Each side surface 11c of the plurality of storage boxes 11 constituting the furniture body 12 is laid on the floor surface F, and the top plate 11a and the bottom plate 11b are arranged so as to face each other. Next, the support rod 13 in a state in which the length adjustment mechanism portion 15 at least at the upper end portion is loosened is inserted into the interior of the furniture body 12 through the openings 16 of the storage boxes 11 arranged on the floor surface F. Thereafter, the entire storage box 11 is raised from the floor F with the top plate 11a and the bottom plate 11b facing each other, and the storage boxes 11 are installed in a stacked state. Thus, after raising the furniture main body 12 to the floor surface F, each storage box 11 is aligned in the height direction, and the position of the opening part 16 of each storage box 11 is piled up correctly. Finally, the lower end portion of the support bar 13 is positioned substantially at the center of the opening portion 16 formed in the bottom plate 11b of the lowermost storage box 11, and the length adjusting mechanism portion 15 at the upper end portion is operated. The pedestal 15a is pressed against the ceiling surface R.

  When the fall-preventing furniture 10A installed on the floor F is thus shaken at the time of an earthquake, each storage box 11 is independently moved in a swinging direction with respect to the lower storage box 11 as shown in FIG. It moves. FIG. 4 shows the lowermost storage box as a reference numeral 11A for the sake of convenience in order to facilitate explanation and understanding of the behavior of each storage box 11 when the furniture body 12 is shaken. The storage boxes stacked one after another are denoted by reference numerals 11B to 11F. 4 shows the behavior of the storage boxes 11A to 11F at the moment when the first shake occurs forward (leftward as viewed in FIG. 4) with the direction of shaking as the front-rear direction of the storage box 11 in the furniture body 12. Is illustrated. Generally, when furniture placed in a room is shaken by an earthquake or the like, the swing acting on the furniture propagates (spreads) from the lower part installed on the floor to the furniture due to repeated shaking. The shaking at the top of the top increases by amplifying its amplitude, and as a result, the furniture falls. However, in the fall-preventing furniture 10A according to this embodiment, as is apparent from FIG. 4, initially, the shaking received by the lowermost storage box 11A in the furniture body 12 spills over the upper part of the furniture body 12. In the spreading process, the second-stage storage box 11B moves slightly forward, and each of the storage boxes 11C to 11D stacked above it receives a large shake as much as it is away from the floor surface F. The amount of movement that deviates from increases. At that time, the movement of the uppermost storage box 11F and the lower storage box 11E is restricted because the inner peripheral edge of the opening 16 hits the support bar 13.

  Thus, the shaking acting on the furniture body 12 is absorbed by the movement of each storage box 11 individually, and the shaking width at the upper part of the furniture body 12 does not increase and does not receive a force enough to fall. Of course, since the support bar 13 penetrates the interior of the furniture body 12, it can be said that the support bar 13 prevents the furniture body 12 from falling down. Rather than preventing the tumble of 12, the stacked storage boxes 11 are actively displaced and absorbed, so that the vibrations that increase as they propagate above the furniture body 12 are absorbed to a considerable extent, thereby supporting them. An excessive load (supporting force) is not applied to the rod 13 itself. In the event of an earthquake, such shaking often lasts for several tens of seconds, but each storage box 11 repeats the movement shown in FIG. 4 in the front-rear direction and propagates as a large shaking toward the top of the furniture body 12. The shaking is absorbed one after another by the movement of each storage box, and the force acting to cause the furniture body 12 to fall is attenuated.

  In addition, in the fall-preventing furniture 10A of the above-described embodiment, in order to explain the basic principle, it is about an example in which six storage boxes 11 are simply stacked, but actually, it is shown in FIG. Thus, various storage boxes 11 can be combined to constitute the fall prevention system furniture. That is, the fall prevention system furniture 30 shown in FIG. 5 is configured such that the fall prevention furniture 10B in which storage boxes having different sizes are combined is arranged next to the fall prevention furniture 10A shown in FIG. It is. In the fall-prevention furniture 10B in which storage boxes having different sizes are combined, two storage boxes 11 are arranged at the bottom, and a large storage box 22 having a width twice that of the lower storage box 11 is placed thereon. Furthermore, there are three stages stacked on top of each other and two storage boxes 11 arranged side by side. In the case of such a fall-preventing furniture 10B, two openings (not shown) are formed in the top plate and the bottom plate of the large storage box 22 in accordance with the above-described gist of the present invention. That is, the two openings formed in the large storage box 22 are respectively formed at positions corresponding to the openings 16 formed in each of the two storage boxes 11 stacked in the height direction. Two support bars 13 are erected so as to pass through the continuous openings.

  Even in the fall prevention system furniture 30 configured in this way, the behavior of the storage boxes 11 and 22 with respect to shaking during an earthquake is exactly the same as that of the fall prevention furniture 10A of the embodiment shown in FIGS. As the storage boxes 11 and 22 are displaced relative to the lower storage boxes 11 and 22, the shaking is absorbed, so that the upper shake does not occur and the fall can be prevented.

  In addition, in the fall-preventing furniture 10A, 10B of each embodiment described above, the opening 16 formed in the top plate 11a of the uppermost storage box 11 in each storage box 11 constituting them and the support bar 13 passing therethrough. If a material that does not hinder the relative movement of the support bar 13 with respect to the top plate 11a, such as a sponge that is easily crushed when subjected to compression, is disposed in the gap 17 between It is possible to prevent dust from entering the main body 12 from above. Moreover, in the fall prevention furniture 10A, 10B of the above-described embodiment, the upper end portion and the lower end portion of the support bar 13 are stretched by operating the length adjusting mechanism portion 15 to press against the ceiling surface R and the floor surface F. However, the present invention is not limited to such an example, and as shown in FIG. 6, either one or both of the upper end and the lower end of the support bar 13 are embedded in the ceiling and floor. It is also preferable to fix it more firmly. In this case, the recess 21 shown in FIG. 6 is formed in advance on the ceiling and floor of the frame at the place where the furniture is supposed to be placed, and the fall prevention furniture is placed at the actually assumed position. When being used, the upper end and lower end of the support bar 13 are placed in the recess 21, and the upper end of the support bar 13 is filled with a filler that hardens after filling, for example, concrete 22, and develops the necessary strength. The part and the lower end can be substantially embedded in the concrete or the like.

  As described above, according to the fall prevention furniture of the embodiment described above, when the furniture body shakes during an earthquake, each storage box reciprocates with respect to the lower storage box on which it is stacked. The swaying to the upper part of the furniture body is absorbed, and the swaying of the swaying to the upper part of the furniture body can be prevented, and as a result, the furniture body can be prevented from falling.
