Description

  The present invention relates to a seismic holding device.

  In the event of an earthquake in a wooden house or condominium, etc., it is safe to evacuate under a table such as a table or other desk in response to a report such as an earthquake early warning. Then, because it collapses in an earthquake, the table itself is damaged and it is dangerous. Therefore, there is something that secures safety when evacuating as a resistance rod that can be gripped by attaching something like a seismic gripping rod under the center of the table and letting it reach the floor . An instrument in consideration of such safety is disclosed in Patent Document 1, for example.

  Japanese Patent No. 3779381

  In Patent Document 1, a support, a flange provided at the top of the support, an adjustment support attached to the lower part of the support so as to be movable and adjustable in the axial direction, the flange and the table or desk top. It consists of a mounting plate for reinforcing the top plate interposed between the lower surface of the plate, the mounting plate can be divided in a plane direction, and an adhesive layer is provided on the side to be mounted on the top plate, A seismic gripping bar is disclosed in which the flange portion is configured to be attached to a lower portion of the top plate via the mounting plate fixed to the lower surface of the top plate. Basically, this holding bar is provided with a flange part at the upper part of the support column and an adjustment support body at the lower part, and the flange part is fixed to the top plate side. However, the basic thing of this gripping bar is that the upper part is attached to the table surface, but the seat of the lower part of the adjustment support is just resting on the floor, There is a risk that the original normal state may not be maintained due to the table falling or blindly moving due to the initial thrust or roll caused by the earthquake. As a result, not only is it harmful to residents, furniture, inner walls, window glass, etc., but the table may not be able to be grasped by the fall of the table, or it may be harmed by being carried around with the table. Maybe there. Moreover, since the table itself collapses and moves around, there is a big problem that the evacuation area is not under the table.

  The present invention is intended to solve such a conventional problem. By defining that the tables are not pushed up or blinded by the vibration caused by the earthquake, the present invention can be applied to residents, furniture, inner walls, window glass, etc. Inexpensive and safe to protect residents from earthquakes as a safe and secure evacuation site that can withstand the impact load from the top or side without moving and holding the table as much as possible The purpose is to provide a seismic holding device that takes into account its widespread use, and in particular, its structure has been greatly simplified so that it can be provided at low cost, and even an amateur can install it very easily and reliably. The purpose is to enable safe and secure evacuation in the event of an earthquake.

In order to achieve the above object, the invention according to claim 1 is directed to a table with legs such as a dining table and a desk, directly on a floor surface or indirectly through a rug laid on the floor surface. A seismic holding device for fixing and fixing, comprising at least a column body, a receiving body, a packing material and a fixing means, and the column body is provided with a plurality of fasteners in the center of the back surface of the table top. The upper mounting plate to be mounted and a support column projecting downward from the central bottom surface of the upper mounting plate, and the receiving body has a peripheral wall whose upper end forms an opening and a bottom wall at the lower end of the peripheral wall. In the inner space surrounded by the peripheral wall, which is a bottomed case type, the lower portion of the column is inserted through the opening, and the lower end of the column is configured to have a certain vertical distance from the bottom wall. And the peripheral wall having the opening is put therein It is configured to have a relationship of being spaced apart with a circumferential interval so as to allow relative movement in the horizontal direction along with the tables with respect to the lower part of the pillar and allow the packing material to be inserted into the internal space through the opening. It can be fixed to the floor or rug directly or indirectly via a backing plate by the fixing means made of adhesive or the like, and the packing material can be a granular material, a small block material, a solidified material, etc. The struts are received by being placed around the struts in the receiving body through the openings alone or in appropriate combination .

  Since the present invention is configured as described above, it is possible to reduce damage to residents, furniture, inner walls, window glass, etc. as much as possible by stipulating that tables are not pushed up or blinded by vibration caused by an earthquake. As a safe and secure evacuation site that can withstand the impact load from above and from the side without being moved, it can effectively protect residents from earthquakes, and its structure is greatly simplified The purpose is to make it possible to provide it at low cost, and to enable even an amateur to install it very easily and reliably and to evacuate safely and effectively during an earthquake.

1 to 6 show an embodiment in which an anti-seismic holding device M (in the following embodiments, the shape, structure, material, etc. are slightly different but are unified with the symbol M) is provided between the table T and the floor 1. The form is shown.
The embodiment shows a four-legged table (dining table (dining table), a table, a desk (for home use, for desks, etc.) that is equipped with a two-legged type (see FIG. 20 (bottom view)). This can also be applied to the

  1 is a floor (floor surface) in a broad sense, and includes all of wooden floors (which may be resin plates), concrete floors, and tatami mats. On top of this floor 1 is a top plate 2 and four legs. The table T which consists of 3 ... and was reinforced with a side connecting material (not shown) is installed as an existing one (including a new one). Also included in the four-leg model is a leg with a square frame on the side. Those with more than four are also included in the four-leg type here. The four-leg type refers to all of the types that are separated from the lower side of the top plate as in the case of the two-leg type and are not mounted with a passing member between the two legs, and the two-leg type refers to the passing member. The one that is mounted. That is, the table T is classified according to the presence or absence of a transfer member. An example of the table T is a two-leg type, and an example of the table T is a four-leg type.

  The seismic holding device M is mainly composed of the column body 5, the receiving body 10, the filling material 18, and the fixing means 20. The column body 5 is made of steel, and has a round plate shape or a square plate shape with an upper mounting plate 7 having a hole 6 and a cylindrical or square shape that extends downward with its upper end fixed to the center bottom surface of the same mounting plate 7 by welding. It consists of a cylindrical column 8, and the lower end of the column 8 is open in FIG. 1 and closed with a lid 9 in FIG. The upper mounting board 7 is mounted by being screwed to the center of the back surface of the top plate 2 of the table T with a fastening tool s. A double-sided adhesive having a temporary fixing function and a buffering function may be used in combination with screwing.

  For example, if the length of the leg 3 is 68 cm, the column 8 is shortened to about 58 to 63 cm, which is 5 to 10 cm shorter than that. The length of the support column 8 is changed according to the height of the receiving body 10 and the amount of filling of the filling material 15.

  The receiving body 10 is a bowl container, a trash box or a special container such as a plastic round cylinder (including an ellipse or an ellipse) or a square cylinder (including a square, a long rectangle or other polygons). The bottom receiving case 18 has a peripheral wall (peripheral surface) 11 and a bottom wall (bottom surface) 12 that can be filled (accommodated). The receiving body 10 may be made into a container shape using a board, a bar, a sheet metal, a bamboo material, a rubber material, a bag, or the like, or may be made of earthenware. The filling material 18 may further include a decorative cylinder on the outer periphery thereof.

  The upper end of the receiving body 10 is formed with a large opening 13 in which not only the lower part of the support column 8 is inserted but also the filling material 18 can be easily inserted. The inner diameter of the opening 13 is about 15 to 20 cm, but may be smaller than 15 cm so as not to obstruct the evacuation, and conversely may be larger than 20 cm in order to increase stability. The receiving body 10 includes a bag-like object that is open at the top. In this case, it is advantageous in that it can be folded and compacted for packing and transportation.

A plurality of through holes h1 are concentrically opened on the bottom wall 12 of the receiving body 10, and through holes h2 are formed at positions corresponding to the lower receiving plate 15 as well.
The lower receiving plate 15 is generally called a tile carpet, and a base is a rubber-like flexible mat, and a pile is integrally planted on the entire upper surface thereof. The base plate 15 may be made of a material other than rubber as the base is generally called a lug, or may be a wooden plate, a resin plate, a metal plate, a rubber plate, or the like.

The receiving body 10 and the upper mounting plate 15 are connected by passing a set screw b through the lower through hole h2 and the upper through hole h2 and screwing a nut n with a seat. Of course, both 10 and 15 may be connected by adhesion or adhesion, and the fasteners b and n can be used in combination with these adhesion or adhesion methods.
It should be noted that a cushioning seat 14 such as various rubbers or elastomer resins is interposed between the receiving body 10 and the lower receiving plate 15 so as to have a function of cushioning the load from above. Good. Further, if the set screw b has a wide area head or a wide washer is interposed, the set screw b is prevented from coming off and the connection can be reliably obtained.

  The fixing means 20 is made of a double-sided pressure-sensitive adhesive layer material with a release liner 21 or an adhesive, and is affixed to the appropriate place (corner, center portion, etc.) of the backing plate 15 with the release liner 21. The adhering means 20 may be affixed to the backing plate 15 at the time of factory shipment or may be affixed at the time of table T installation work.

  As shown in FIG. 2, the packing material 18 is made of various types of sand (including sand that hardens when applied with water) 18a ..., coral grains, volcanic ash, lava grains, shredded fine pieces (add water to harden it) Small, such as large and medium stone materials (including pumice and lava stone) 18b ..., resin balls, refill pipes (for putting in pillows with short resin tubes) It is composed of a lump material, and a solidified material (including an adhesive, a deodorant, a fragrance, etc.) that is initially solid or liquid and solidifies after injection.

  The sand and the like can be used in combination with each other. For example, the stone material 18b is laid on the bottom of the receiving body 10 and sand is filled around the entire support column 8 thereon. If clay (large block or small block) is put in the bottom instead of stone, the impact load from above and below can be reduced. Further, when rubber particles (including powdered materials) or balls are put into the filling material 18 alone or mixed with sand or the like, a buffering effect is obtained.

  If the deodorizer (including activated carbon) is added to the filling material 18 alone or mixed with other materials such as sand, it is useful for improving the indoor environment. When the filling material 18 is filled with sand, pebbles or the like in the bottom layer and activated carbon or the like in the top layer, the center of gravity is lowered and the vibration is less likely to be shaken by the vibration, and the column 8 and the table T are effectively and stably held. On the other hand, the filling material 18 may be used as a plant growing material to grow a favorite plant. This plant may be artificially decorative.

In addition, as shown in FIG. 2, if the necessary fasteners s... There is no need to search, and work on site can be done immediately. The receiving material 18 can be enclosed in the receiving body 10.
Further, the receiving body 10 can be fixed to the floor 1 by omitting the lower receiving plate 15 and attaching the fixing means 20 to the bottom of the receiving body 10. In this case, the fixing means 20 can be fixed to the receiving body 10.

  As for the seismic holding device M, for example, the one shown in FIG. 2 can be obtained as a set by customers through home delivery or a store. At the time of shipment, the receiving body 10 and the lower receiving platen 15 may be separated from each other or may be connected by the fastening devices b and n. When separated, the lower receiving plate 15 is wound into the receiving body 10 or wound around the support column 8. The filling material 18 is also provided in the receiving body 10 and required to be compact.

  At the installation location, first, as shown in FIG. 3, the table T is reversed and the upper mounting plate 7 is placed in the center of the top plate 2 so that the upper mounting plate 7 is fastened with the fasteners s. The column body 5 is attached to the table T side. On the other hand, the receiving body 10 with the lower receiving plate 15 is placed under a preferable indoor layout on the floor 1 as shown in FIG. At this time, the release liner 21 (see FIG. 1) may be peeled off and the receiving body 10 may be adhesively fixed on the floor 1 with the fixing means 20, or the liner 21 is peeled off after the layout is determined at the final stage. You may do it.

After that, the table T with the column body 5 is returned to the original state so that the column 8 enters the receiving body 10 as shown in FIG. Then, the position is adjusted again so that the positions of the receiving body 10 and the table T fall within a desired layout desired in the room. When it is finished, as shown in FIG. Prior to packing, the release liner 21 may be peeled off to fix the receiving body 10.
When the filling material 18 is completely packed, the corner portion of the lower receiving plate 15 is turned up as shown by the arrow in FIG. 1 to peel off the release liner 21 and fix the fixing means 20 to the floor 1. In the case of this embodiment, since the adhering means 20 is located outside the receiving body 10 as viewed from above, the turning-up can be performed freely.

  As described above, since the support body 5 and the floor-side receiving body 10 are separated, the layout adjustment can be performed easily and reliably. Further, since the support body 5 and the receiving body 10 can be connected to each other only by inserting the filling material 18, for example, an adjuster member such as a separate tube or a screw rod whose length can be adjusted is not required for the support 8. Not only can the structure itself be simplified, but the work can be completed without requiring a complicated work for the adjustment. In addition, forgetting to lock the support column 8 and the adjuster member, or the fact that the lock is not sufficient prevents the device from functioning during an actual earthquake.

  Further, the presence of the clogging material 18 not only effectively absorbs and attenuates the impact load from above and below during the earthquake by its mutual frictional action, but also effectively attenuates the roll. In particular, if the filling material 18 is sand or an elastic material (such as a rubber piece) is mixed, the above-mentioned damping action becomes larger, and the receiving body 10 is made of resin, synthetic rubber, copper or aluminum. If it is an elastic bowl made of sheet metal or the like, it exhibits a further damping effect.

Further, if the receiving body 10 is fixed to the floor surface via a wide lower receiving platen 15, only horizontal force is applied to the fixing means 20 even if rolls are applied due to vibration caused by an earthquake. The fixing means 20 having extremely strong characteristics against the horizontal force is a device that is difficult to peel off and is stable. The fixing means 20 may be provided in the center of the lower receiving plate 15 so that it can be temporarily fixed in advance.
In the above-described embodiment, the support column 8 is slightly deeply embedded by the filling material 18, but the lower end of the support column 8 can be placed in the filling material 18 only slightly, or the support column 8 and the filling material 18 can be placed. Can be at the same level.

  As shown in FIG. 6, an emergency earthquake alarm 27 can be attached as an accessory using the back surface of the top plate 2 of the table T, the receiving body 10 or the like. 28 is an equipment holder which can be attached by screwing or double-sided bonding. In this case, since there is a notification under the table T which is an evacuation place, even if it is in the dark, if you evacuate in the direction of sound generation, it will be automatically under the table T, so it is reasonable. In this case, if the alarm device 27 is provided with an emergency light that illuminates the bottom of the table T in conjunction with the earthquake, evacuation is safe and reliable. The alarm device 27 may be a battery type.

As shown in FIG. 7, when the diameter of the column 8 is 60 mm, the diameter of the receiving body 10 may be as small as 120 to 150 mm. In addition, if the hole 8a is provided in the lower part of the support | pillar 8, sand will flow to the bottom through the hole 8a, and the transmission of the force of an up-down direction will be ensured.
As shown in FIG. 8, the receiving body 10 may be provided with an outer flange 10 a and may be connected to the lower receiving plate 15 by opening through holes h <b> 1. Further, as shown in FIG. 9, the outer flange 10a may have a partially protruding piece as shown in the lower column.
As shown in FIG. 10, if the lower receiving plate 15 has substantially the same diameter as the receiving body 10 and the fixing means 20 is attached to the bottom surface thereof, the weight of the filling material 18 is added to the fixing means 20 and the adhesive fixing performance. Will improve.

As shown in FIG. 11, the upper mounting board 7 may be a saucer type with a flange, and a safety cover R may be attached around the support column 8. If the outer peripheral surface of the safety cover R is uneven, it is prevented from coming off in the direction of the arrow.
As shown in FIG. 2, a disc-shaped lid 9 may be welded to the lower end of the support column 10 so that the load from above and below is reliably transmitted.
As shown in FIG. 12, the lid 9 may have a slightly larger diameter than the support column 8, and in this case, the support column 8 is prevented from coming off.

As shown in FIG. 13, the lid 9 may be a cap type made of synthetic rubber, silicone rubber, or elastomer resin. If the lid 9 is fixed to the column 8, the column 8 is prevented from coming off and the impact load from above and below is attenuated and received.
As shown in FIG. 14, the lid 9 </ b> A may be a belt-like plate that is welded in a state of extending in a wing shape.

  The lids 9 and 9A shown in FIG. 12 to FIG. 14 reliably transmit the load from above at the time of the earthquake more effectively on the surface than when the force is transmitted to the packing material 18 only by the lower peripheral circle of the support column 8. The lid 9 and the lid 9A having a diameter slightly larger than that of the support column 8 have a function of preventing the wing portion from being pulled out from the clogging material 18 due to the resistance of the wing during the push-up action due to the earthquake, If it is set as narrow thing 9A like FIG. 12 and FIG. 14 of FIG. 12 which protrudes by a small diameter rather than a wide surface shape compared with the diameter of the support | pillar 8, the filling material 18 is put in the receiving body 10. FIG. At this time, the filling material 18 also has a function of facilitating the filling by flowing downward through the side of the receiving body 10. 14 may be provided with a through hole 9a for facilitating the drop of the filling material 18.

As shown in FIG. 15, a table 9 is provided with a lid 9 at the lower end of a support column 8, and a retaining protrusion 10 b having a triangular or semi-circular cross section is provided on the inner periphery of the receiving body 10. Even if the column 8 is lifted, the lid 9 resists like a wedge even if the lid 9 tries to lift the clogging material 18, thereby preventing the column 8 from being lifted and preventing the table T from being pushed up.
The retaining protrusion 10b may be a protrusion as shown on the inner periphery of the receiving body 10 in FIG.
Further, the protrusion 10b may be formed by integrally molding the peripheral surface of the receiving body 10 into a narrow body as shown in the right column of the figure.

  Further, as shown in FIG. 16, if the anchor 19 such as a bead is suspended from the both ends by being attached to the column 8 and embedded together with the filling material 18, the column 8 can be prevented from coming off. The anchor 19 may remain linear as shown in the left column. The anchor 19 may be a link chain type such as metal or resin, a simple chain, a wire, or various strings as shown in the right column. In addition to the wire or the like, the wire connecting the anchor 19 may be a rubber string or the like. There may be a plurality of anchors 19.

In addition, the lower receiving plate 15 can employ various geometric shapes such as a round shape and a polygonal shape as shown in FIG.
Further, as shown in FIG. 17, a part of the receiving plate 15 is punched out at a factory like a virtual line to form a plurality of holes 15b and a base material 15a formed by punching is used to form a base material on the upper side. While fixing the stopper 16 having a diameter larger than 15a, the fixing means 20 such as a double-sided adhesive is adhered to the lower side of the base material 15a as having a release liner 21 to constitute one fixing tool G, The base plate 15 may be fixed. The holes 15b are arranged on the outer diameter side of the bottom wall 12 of the receiving body 10. The base material 15a may be a separately formed disk. The base material 15a and the stopper 16 may be an integrally molded product made of resin or the like.

  In addition, if the stopper 16 is provided with a turning groove 16a and is turned by a turning tool (not shown), the fixing means 20 can be easily peeled off, and is reset after the layout of the lower receiving plate 15 is adjusted. Then you can change the layout over and over again. The stopper 16 can be adhesively fixed so as to hang on the outer peripheral edge of the lower receiving plate 15 like a virtual line. After laying out the lower receiving plate 15 with the receiving body 10 at a preferred position on the floor surface 1, the lower receiving plate 15 is fixed if the fixing tool G from which the release liner 21 is peeled is fitted into the holes 15 b. When the stopper 16 hits the lower receiving plate 15, the lower receiving plate 15 is prevented from coming off.

  In this way, after the layout of the base plate 15 is finished or after the filling material 18 is further packed, it is advantageous in that the base plate 15 can be separately fixed by the fixing tool G. In the case of such a carpet-shaped base 15, the fixing means 20 can be brought into a fixed state by turning up after laying out the base 15, but the base 15 is a plate. In such a case, the fitting method using the above-described fixing tools G... Is advantageous because it can be fixed independently.

In the embodiment of FIG. 18, the support body 5 is made of steel or a resin pipe, and a filler 29 such as sand is put therein to enhance the strength. As the filler 29, a lighter material such as charcoal, water or oil can be selected. Reference numeral 8b denotes an inlet for the filler 29, which is closed with a seal (not shown).
If the lid 9 has a slightly larger area than the column 8 as shown in the figure, the upper and lower loads caused by the earthquake will be attenuated by this protruding portion as a resistance, and it is not a large disc, so it is a packing material. It will not hinder the flow down when filling 18 pieces. Further, an adhesive leg pad p... May be interposed at the bottom of each leg 3 of the table T. This also applies to other embodiments. For example, see FIG.

As shown in the right column of FIG. 18, a cushioning member E made of sponge (including an ultra-low-resilience material used for pillows and the like) that can move up and down around the column 8 is provided. After inserting into the receiving body 10, the cushioning member E is lowered and inserted into the receiving body 10 after laying a receiving material 18, such as sand, gravel or clay, on the bottom layer of the receiving body 10. By doing so, an effective buffering function is exhibited on the support column 8 side and the receiving body 10 side particularly when rolling.
The buffer member E exhibits the same buffer function even if it is replenished separately after the filling material 18 is inserted as a rod-shaped member (upper right column) or a small-piece member. The above applies also to other embodiments.

The embodiment of FIG. 19 (bottom view) shows another proposal in which two, three, or four struts 8 are brought together.
The embodiment of FIG. 20 (bottom view) shows a support column 5 for a two-leg table T formed by connecting a pair of wide legs 30 and connecting them with a transfer member 31 at an intermediate height. The column body 5 is a pair of columns 8 separated from each other and connected by an upper mounting plate 7 so that the upper mounting plate 7 is perpendicular to the back surface of the top plate 2 and the column 8 is parallel to the top plate 2. Then, the upper mounting board 7 is attached to the top board 2 by turning between the top board 2 and the delivery member 31 and then turning so that the struts 8 straddle the delivery member 31.
In this case, the receiving body 10 is a single piece, but a plurality of receiving bodies 10 may be provided corresponding to each support column 8.

  As shown in the right column of the figure, the pair of struts 8 each provided with the upper mounting plate 7 may be a square pipe, which may be a strut body 5 formed by welding the connecting material 32 between the lower ends. Further, as shown in the right column, a bent plate-like column 8 may be used, and a lower end may be connected by a connecting material 32. When the upper mounting plate 7 is paired, the transfer member 31 is passed between them so that the upper mounting plate 7 can be easily fixed to the table T. When the target is a four-leg type table T, the upper mounting board 7 may be one piece connecting between the columns 8. The column body 5 of each example can be attached to a four-leg type table T. The same applies to other embodiments.

  The embodiment of FIG. 21 (bottom view) shows a structure in which the support column 8 is a square pipe, and the square may be a square or an oblong shape. An example in which a two-legged table T may be supported is shown.

  Furthermore, in addition to showing an example in which lip-shaped grooved steel may be brought together, a proposal that two-legged table T as shown in FIG. 20 may be separated from each other instead of being brought together. Show. When the square support 8 is used, as shown in the lower left column of FIG. 21, it is shown that the upper mounting plate 15 can be configured by fixing or welding the angle to the upper end of the support 8.

  In the embodiment of FIG. 22, when a rug 33 is already laid on the floor 1, the rug 33 is fixed to the floor 1 via the fixing means 20. It is what you do. The adhesive in this case is, for example, a laminate of Nitto Denko double-sided pads X (trade name; Hyperjoint H9012) or SHIMADA security crime prevention adhesive sheet Y (the same sheet is a strong adhesive mainly on one side). Therefore, it is effective to use it in a folded state so that it comes to the front and back, and this is also applied to other parts (the bottom part of the backing plate 15).

The embodiment of FIG. 23 shows a wooden support 5. The upper mounting board 7 may be steel or the like, and the column 8 may be a solid round bar. Further, the support column 8 may be a four-sided combination type as shown in the right column in addition to the solid state.
The embodiment of FIG. 24 is a bifurcated type that is applied to a two-legged table T as shown in FIG. 20, and the upper mounting plate 7 and the support column 8 are configured as a pair separated from each other. As shown in the right column of FIG.
In the embodiment of FIG. 25, the column 8 in the lower left column of FIG. 21 is made of wooden poles. A braking piece 35 may be attached to the lower part of the support column 8.

  FIG. 26 shows another embodiment. In this embodiment, the lower receiving plate 15 is provided with a mesh-like or porous (lower right column) opening 15c, and the lower receiving plate 15 is placed on the floor surface 1. FIG. The base plate 15 and the receiving body 10 are fixed to the floor surface 1 by screwing the fasteners s through the through holes 15c that match the joints 1a of the floor surface 1 when laid out on the floor surface 1. Is. Since the screwing of the fastening tool s is at the joint 1a, the damage is mild and inconspicuous, and the screwing through the groove makes it easy to screw.
