Abstract

PROBLEM TO BE SOLVED: To improve the function of a cabinet stopper. SOLUTION: A cabinet 1 is supported by a flexible base plate 2, and a stopper part 2a protruding outward from the cabinet is formed on the base plate 2. If the cabinet 1 tilts (quakes) when an earthquake occurs, the stopper part 2a on the base plate 2 is warped and deformed, so the energy of the earthquake is absorbed. In addition, since the base plate 2 is in contact with the floor surface F, the base plate 2 can easily slide and move on the floor surface F, so the energy of the earthquake is absorbed. Therefore, the function of the stopper can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a furniture such as a cabinet from being overturned in the event of an earthquake, provided on a lower surface of the furniture.

[0002]

2. Description of the Related Art Cabinets generally have a smaller depth dimension than a frontage dimension and have a high center of gravity, so that they tend to fall down in the front-rear direction during an earthquake. Therefore, a device for improving stability with respect to the front-back direction is provided on the lower surface of the cabinet.

As one example, Japanese Utility Model Publication No. 4-24990 discloses that a plurality of strip-shaped fall prevention plates (outriggers) projecting forward from the cabinet are attached to the lower surface of the cabinet. In addition,
No. 9 discloses that a fall-prevention plate (supporting plate) that comes into contact with the floor in front of the cabinet is fastened to the front surface of the lower end portion of the cabinet with screws.

Further, Japanese Patent Application Laid-Open No. Hei 9-135742 describes that a cabinet is supported by a thick fall prevention plate which is wider than the frontage of the cabinet and projects forward or backward of the cabinet.

[0005]

In this type of overturn prevention device, a large moment acts on the overturn prevention plate due to the tilting of the cabinet during an earthquake. For this reason, when the fall prevention plate is formed in a strip shape as in Japanese Utility Model Publication No. 4-24990, a large external force acts on the attachment point between the fall prevention plate and the cabinet during an earthquake. The mounting point between the fall prevention plate and the cabinet is damaged.
There is a possibility that it will be deformed and lose the fall prevention function.

Also, in the configuration disclosed in Japanese Utility Model Application Laid-Open No. 55-133859, since a large external force acts intensively on the fastening point between the cabinet and the fall prevention plate during an earthquake, the fastening point is broken and the fall prevention function is provided. There was a risk of losing it. On the other hand, according to the configuration of Japanese Patent Application Laid-Open No. Hei 9-135742, since the overturn prevention plate is spread over the entire lower surface of the cabinet, the moment due to the tilting of the cabinet does not act intensively on a specific portion. Therefore, there is no possibility that the fall prevention plate is damaged or detached from the cabinet.

Incidentally, in order to improve the function of preventing the cabinet from tipping over, it is desirable to absorb (buffer) as much as possible the energy acting on the cabinet due to the earthquake. However, since the fall prevention plate disclosed in JP-A-9-135742 has a thick rigid structure, the energy of the earthquake acts directly on the fall prevention plate and the cabinet, and in addition to this, the rigid structure has a fall prevention plate. The cabinet is difficult to slip on the floor and does not absorb the energy of the earthquake by sliding movement, so the cabinet tends to shake violently, and the fall prevention function is not always sufficient.

Further, when the fall prevention plate is formed to have a thick rigid structure as disclosed in Japanese Patent Application Laid-Open No. 9-135742, there is a problem that a person easily trips when the fall prevention plate is exposed to the floor. An object of the present invention is to solve these problems of the prior art.

[0009]

Therefore, according to the present invention, a flexibly deformable base plate for supporting the furniture is arranged on the lower surface of the furniture, and the furniture is placed on the base plate in a state of being in contact with the furniture. The fall prevention part that protrudes outside is provided integrally. In this case, the base plate may be configured separately from the furniture and attached at the site, or the base plate may be fixed to the furniture in advance. Further, when the base plate is formed separately from the furniture, the base plate may be fixed to the furniture by suitable means such as screwing, or may be assembled by fitting or the like.

[0010] The position of the fall prevention portion and the size of the protrusion may be set according to the shape and installation form of the furniture. For example, in the case of furniture whose depth dimension is smaller than the width of the frontage, and when the furniture is installed away from the wall of the building, the fall prevention unit is directed to both the front and rear directions of the furniture. It should be protruding. On the other hand, when the back of the furniture is overlaid on the wall or partition of the building, the fall prevention portion may be projected only in front of the furniture.

Further, when used for furniture having a substantially square or circular shape in plan view, the fall prevention portion may be formed over the entire circumference of the base plate.

[0012]

According to the present invention, even if the quake of the earthquake acts on the furniture and the base plate, the fall prevention portion of the base plate is flexibly deformed (elastically deformed) so that the energy of the earthquake is absorbed and moderated. . In addition, since the elastic restoring force due to the bending deformation of the base plate acts to return the inclination of the furniture, the stability of the furniture is high. Furthermore, the fact that the base plate is in surface contact with the floor surface and that the base plate floats from the floor surface due to the flexural deformation of the base plate are combined, so that the furniture and the base plate are subject to an earthquake. Easy to slide on the floor.

Since the overturn preventing portion is provided integrally with the base plate supporting the furniture, even if a bending moment is generated in the overturn preventing portion of the base plate due to the tilting (swinging) of the furniture, the base is prevented. Large external forces do not act intensively on any particular part of the plate, so that the base plate is not damaged. As described above, according to the present invention, while preventing damage to the base plate, the seismic energy can be absorbed and mitigated by bending deformation of the base plate, and the seismic isolation function by furniture sliding on the floor surface can be achieved. As a result, the function of preventing the furniture from overturning can be significantly improved.

In addition, since the base plate is thin, even when the base plate is exposed on the floor surface, it is possible to prevent or significantly suppress a person from tripping.

[0015]

Next, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show a first embodiment, in which FIG. 1 is a perspective view showing a state where a cabinet 1 and a base plate 2 are separated, and FIG. 2 is a view showing a state where the cabinet 1 and the base plate 2 are separated. FIG. 3 is a front sectional view, FIG. 3 is a partial sectional view in an assembled state, and FIG.

The cabinet 1 includes a main body 3 and a door 4 of a double door type or a sliding type (a drawer may be provided, or a drawer and a door may be arranged side by side). As shown in FIGS. 2 and 3, the lower surface of the main body 3 is provided with a protruding frame portion 5 projecting downward from the outer peripheral surface slightly inward. On the other hand, the base plate 2 is made of a flexibly deformable plate material (metal plate) such as a steel plate or a stainless steel plate. The width of the base plate 2 is the same as the width of the cabinet 1 (width in the width direction) (the width may be narrow), but the width of the front and rear is larger than the depth of the cabinet 1. The base plate 2 is formed with a pair of front and rear overturn prevention portions 2a that protrude from the front and rear of the cabinet 1.

At the front and rear central portions of the base plate 2, a frame 6 into which the convex frame portion 5 of the cabinet 1 fits exactly is fixed by appropriate means such as welding or screwing. Although the frame 6 is formed in the same shape and dimensions as the main body 3 of the cabinet 1 in plan view, the frame 6 may be formed slightly smaller than the main body 3 of the cabinet 1. As shown in FIG. 3, the main body 3 of the cabinet 1 is fixed to the frame 6 with screws 7, but the convex frame 5 of the cabinet 1 may be simply fitted into the frame 6. When fixing with the screw 7, the screw 7 may be screwed in from the horizontal direction.

Describing specific dimensions, the cabinet 1 has a depth of about 420 mm, a width of about 900 mm,
When the height is about 1800 mm, the protrusion size of the overturn prevention portion 2a on the base plate 2 may be set to, for example, about 150 to 200 mm. The thickness of the base plate 2 depends on the material and the weight of the cabinet 1, but may be around 3 mm in the case of a normal steel plate (iron plate).

The frame 6 and the base plate 2 may be configured to be transported separately, and may be fixed to each other by a suitable means such as screwing. As shown by a solid line and a dashed line in FIG. 4, when the floor F fluctuates due to the earthquake, the cabinet 1 tilts in the front-rear direction, and the base plate 2 also moves along with the cabinet 1.
Tilt back and forth with. Thus, when the cabinet 1 is tilted back and forth, the fall prevention portion 2a of the base plate 2 is bent and deformed, so that the energy of the earthquake is absorbed. In other words,
The cabinet 1 is tilted in the front-rear direction while being buffered by a spring by the bending deformation of the base plate 2.

Further, when the cabinet 1 is tilted in the direction of arrow A, the reaction force (elastic restoring force) of the overturn preventing portion 2a acts in the opposite direction as indicated by arrow A '. The reaction force of the plate 2 acts in the opposite direction as indicated by the arrow B ', and the elastic restoring force of the base plate 2 acts to prevent the cabinet 1 from tilting. (Swing) is effectively attenuated.

Further, since the base plate 2 is in surface contact with the floor surface F, friction between the base plate 2 and the floor surface F is reduced. In order to swing in a state of bouncing on the floor surface F due to bending deformation, as shown by the dotted line and the arrow C,
Cabinet 1 is easy to slide on floor F. As described above, the seismic energy is absorbed by the bending deformation of the base plate 2, the bending deformation of the base plate 2 acts to suppress the tilt of the cabinet 1, and the cabinet 1 moves on the floor F. Combined with easy sliding movement, the function of preventing the cabinet 1 from tipping over can be improved.

As shown by the dashed line 2a 'in FIG.
Tilt the fall prevention part 2a downward at a gentle angle in side view,
When the cabinet 1 is placed, the overturn prevention portions 2a may be deformed flat by the weight of the cabinet 1 so that the cabinet 1 comes into close contact with the floor surface F. With this configuration, the ground pressure at the tips of the two tip-over prevention portions 2a is the highest, so to speak, the legs are opened and stepped on, so that the stability of the cabinet 1 is hard to tilt, and the base plate is hardly tilted. Since 2 stores an initial elastic force for preventing the cabinet 1 from tilting, there is an advantage that the overturn prevention function is further improved.

FIG. 5 et seq. Show another embodiment.
In the second embodiment shown in FIG.
The base plate 2 is directly fastened to the lower surface of the main body 3 by screws 7. The third embodiment shown in FIG. 6 is an example in which the rear surface is applied to a cabinet 1 in which the back surface is overlapped with a wall W of a building or a partition. In this case, the overturn prevention portion 2a projects only forward.

In the fourth embodiment shown in FIG.
A hole 8 having an appropriate shape and area is formed in a portion surrounded by the frame 6 among the holes. This is for weight reduction, and
This is because the base plate 2 can be brought into contact with the floor without rattling even if the floor surface F has irregularities. As shown by a dashed line in FIG. 7, an appropriate number of ribs 9 extending in the front-rear direction may be formed in the overturn prevention portion 2 a of the base plate 2. With this configuration,
Even when the base plate 2 is thin, the spring force of the overturn prevention portion 2a can be increased. If the base plate 2 is too hard, a hole may be formed in the fall prevention portion 2a.

In the example of FIG. 7, the corner portion of the tipping prevention portion 2a is formed in an arc shape (it may be chamfered). This is because when a carpet or a carpet is laid on the floor F, the corner portion of the fall prevention portion 2a is prevented from being caught on the carpet or the carpet, and is easily slid. In the fifth embodiment shown in FIG. 8, a portion of the base plate 2 surrounded by the frame 6 is swelled and deformed upward. This is to improve the adhesion of the base plate 2 even if the floor surface F has irregularities. In this case, the strength of the base plate 2 can be improved.

In the sixth embodiment shown in FIG. 9, two frames 6 are arranged side by side on one base plate 2 and two cabinets are supported by one base plate 2. Three or more cabinets may be supported by one base plate 2. FIG.
The seventh embodiment shown in FIG. 7 is applied to furniture having a substantially square shape in a plan view. In this case, since the furniture easily falls in any direction, the fall prevention portion 2a is formed so as to extend over the entire circumference. When the furniture is circular, the base plate 2 may be formed in a circular shape so that the overturn preventing portion extends over the entire circumference.

Although the embodiments of the present invention have been described above, the present invention can be further embodied in various forms. Further, the present invention can be widely applied not only to cabinets but also to furniture requiring a fall prevention function.
