Description

  The present invention is used for preventing a fall, a refrigerator, a desk, a cabinet, a large television, a computer server, a home such as a copy machine, etc., a fixed structure for offices from moving or falling due to strong vibration such as an earthquake. The preventive tool will be described in more detail. Fixing a home or office fixing structure to a fabric such as a carpet or carpet laid on the floor without performing any special construction to prevent the home or office from falling. The present invention relates to a structure fall prevention device.

In order to prevent furniture and the like from moving and falling due to strong vibration such as an earthquake, the furniture is fixed to a wall, ceiling, or floor using fastening parts such as nails and screws, and mounting brackets.
However, these require construction work, and when replacing furniture, the walls, floors, ceilings, and furniture will be damaged by screws and nails and other fasteners, so the interior can be easily redesigned. There is a problem of disappearance, especially in tenants and rental apartments.

  For this reason, Patent Document 1 (Japanese Patent Application Laid-Open No. Hei 8-242954) discloses a furniture holding lower part; a ceiling contacting upper part; and the furniture as a furniture overturn prevention tool that does not damage a house such as a wall, ceiling, or floor. There has been proposed a furniture overturn prevention tool including an expansion / contraction part that connects a lower part for pressing and an upper part for ceiling contact so as to be fixed at an arbitrary position. Since these fall prevention devices are installed between furniture and the ceiling, things that are not as high as the ceiling, such as large TVs and PC servers, tend to be unusable and unfavorable in appearance. It is in. In addition, because the ceiling and furniture are only in contact with each other, there is a risk that if the fixation at the expansion / contraction part is shifted due to strong vibration or the like, the furniture becomes free and cannot serve as a fall prevention. is there. In particular, since the furniture itself is directly subjected to vibration from the floor, there is a possibility that the expansion / contraction part may be unfixed for a large roll that exceeds the allowable limit of the expansion / contraction part.

  Further, in Patent Document 2 (Japanese Patent Laid-Open No. 10-5069), a hook-and-loop fastener such as Magic Fastener (registered trademark) is attached to furniture, and a fiber sheet that is engaged with the hook-and-loop fastener is attached to the wall. A method of fixing is proposed. However, it is necessary to attach the hook-and-loop fastener to the wall and furniture, and in order to exert the fall prevention function, the fixing force between the hook-and-loop fastener and the wall or the hook-and-loop fastener and the furniture must be larger than the engaging force between the hook-and-loop fasteners. However, since it is difficult to achieve such a fixing force with an adhesive, permanent fixing with an adhesive or mechanical fastening with screws or the like is required.

On the other hand, there is an overturn prevention tool that prevents the floor from falling by fixing furniture to the floor and the like and attenuating vibration propagated from the floor.
For example, Patent Document 3 (Japanese Patent Laid-Open No. 10-61717) discloses a vibration-absorbing plate-like body in which a plurality of buffer plates having different foaming ratios are stacked. However, even though the vibration can be absorbed, there is no disclosure of a method for fixing the vibration-absorbing plate-like body to the floor or furniture.

  As a tipping prevention tool that uses the vibration absorption and vibration isolation of the gel-like body and has been devised to fix the gel-like body, Patent Document 4 (Japanese Patent Laid-Open No. 2000-325168) proposes a tipping prevention tool for electronic equipment. ing. A gel-like body is fitted into a box-shaped frame body, and a fixing locking body such as a belt is attached to the box-shaped frame body, and the fixing body is fixed to a support surface such as a desk. Fixing by a fixing locking body such as a belt can be applied to relatively small furniture such as an electronic device, but cannot be applied to a large fixed structure for homes and offices such as a chiffon, a sideboard, and a cabinet.

  Patent Document 5 (Japanese Patent Application Laid-Open No. 2004-176761) discloses a tipping prevention tool in which front and back surfaces of a hard member such as an engineering resin are bonded to an adhesive body. This overturn prevention tool uses the adhesiveness of the adhesive body to fix the structure and the floor by bringing the prevention tool into close contact with the floor and furniture, respectively. By compressing stress, rebound resilience, and elongation due to the combination of a hard member and an adhesive body, it tries to completely follow rolls such as earthquakes and prevent falls.

  However, since the tipping prevention tool disclosed in Patent Document 5 is fixed by sticking it to furniture and the floor using the adhesive property of the adhesive body, the wall having a pattern with an uneven surface or a rough surface is applied. Since the adhesive body cannot be adhered to the wall surface such as a wallpaper surface or a floor on which a cloth such as a carpet or carpet is laid, the adhesive property inherently possessed by the adhesive body cannot be exhibited. As a result, a fixed structure cannot be fixed to such a floor or wall.

  As an article fixing tool for a wall such as a wall with a pattern that becomes an uneven surface or a rough surface or a wallpaper surface, an elastic body is pressed against the uneven surface of the wall surface, and air between the wall surface is released using an air suction means. Patent Document 6 (Japanese Patent Application Laid-Open No. 2004-293570) proposes fixing by suction. However, suction performed using a vacuum pump or the like is a troublesome operation, and depending on the suction method, there is a possibility that satisfactory fixation cannot be achieved.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent a fixed structure from being overturned by fixing the fixed structure to a cloth such as a wall cloth or a carpet. In addition, the fixed structure can be fixed detachably without damaging the wall cloth or carpet, and the fixing work can be done simply by placing the fixed structure without using tools. It is to provide.

  The fall prevention device for home / office fixed structure of the present invention includes a gel-like body having adhesiveness and vibration absorption, and a support laminated on one side of the gel-like body and abutting against a floor or a wall surface. One surface of the support is an engagement surface in which a large number of engagement portions that can engage with the fabric are erected, the other surface is an uneven surface, and a part of the gel of the gel-like body is By being intertwined with the unevenness of the uneven surface, it is fixed and integrated with the support.

  It is preferable that the engagement portion has a hook shape, a loop shape, a hook shape, or a combination thereof.

  After casting a liquid composition containing a monomer, oligomer, or prepolymer as a constituent material of the gel-like material onto a support, the gel-like body is formed by crosslinking and curing, and the gel-like body and the support are formed. It is preferably fixed and integrated at the contact interface with the body.

The interfacial bonding force between the gel-like body and the support is preferably higher than the adhesive force to the fixed structure to be fixed and higher than the engagement force to the floor surface or wall surface with which the support is in contact. Preferably, the gel-like body is formed by sandwiching a 100 cm ² plate-shaped test piece of the gel-like body with a stainless steel plate and crimping it with 200 N, and then pulling the stainless steel plate in a direction opposite to the crimping direction. The adhesive force is 600N to 2500N. Preferably, the Shore hardness of the gel-like body is 10 or more.

  The fall prevention device for a home / office fixed structure of the present invention having the above-described configuration is preferably used for fixing the fixed structure on a fabric laid on the floor.

  The fall prevention device for fixed structure for home / office of the present invention holds the fixed structure with the adhesive force of the gel-like body and absorbs and attenuates vibration from the floor, so that the vibration propagated to the fixed structure And the structure can be prevented from moving on or away from the gel-like body by the propagated vibration. On the other hand, since the support body of the fall prevention tool is fixed to the floor by engaging with the fabric laid on the floor, the fall prevention tool of the present invention in which the support body and the gel-like body are fixed and integrated is provided on the floor. The fixed structure for home and office can be fixed to the laid fabric, and as a result, the fall can be prevented. And since the fall prevention tool of this invention is only adhering to a fixed structure with the adhesive force of a gel-like body, it is detachable and is only engaged with the fabric laid on the floor. It is also removable from the floor. Therefore, the structure can be fixed without special construction, and the structure can be moved without leaving a scar on the floor or wall when changing the layout.

The structure for preventing overturning of a fixed structure according to the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view illustrating a configuration of a fixed structure overturn prevention device according to an embodiment of the present invention.
The gel-like body 2 is laminated on the concavo-convex surface 1b of the support 1 whose one surface is the engaging surface 1a and the opposite surface is the concavo-convex surface 1b.

  The support 1 may be anything as long as it has an engagement surface 1a having an engagement portion 3 that can be engaged with a cloth such as a carpet and an uneven surface 1b in which the gel-like body 2 can exert an anchor effect. Alternatively, a plurality of engaging portions 3 may be erected on the substrate, or a single-side engaging surface may be obtained by interweaving a rigid yarn such as a nylon yarn as a pile warp yarn separately from the weft yarn constituting the ground structure. 1a may be formed. As such a thing, the surface fastener marketed as a magic fastener (trademark) can be used, for example. Although the engagement surface 1a of the support 1 is a hook-shaped engagement portion in FIG. 1, the support used in the present invention is not limited to this, and the engagement portion constituting the engagement surface 1a. 3 may be a loop shape (FIG. 2 (a)) or a hook shape (FIG. 2 (b)), and may be an appropriate combination of a hook shape, a loop shape, or a hook shape. . In short, what is necessary is just to have the engaging part which can ensure predetermined | prescribed engaging force with respect to fabrics, such as a carpet which is going to apply the fall prevention tool of this invention.

  The uneven surface 1b of the support 1 is uneven so that the gel-like body 2 that does not have fluidity cannot be adhered even by pressing. For example, as the support 1, a base fabric in which a large number of engaging portions 3 are planted or a woven fabric obtained by interweaving a rigid yarn such as nylon yarn as a pile warp yarn separately from the warp and weft constituting the ground structure is used. The engagement portion 3 is formed on the surface to become the engagement surface 1a, and the surface on the opposite side of the surface on which the raised engagement portion 3 is raised or the surface on which the pile of pile warp is formed Becomes the uneven surface 1b.

  In the fall prevention device of the present invention, the uneven surface 1b is not limited to the unevenness that is naturally formed by weaving the woven fabric, and is a surface on which a large number of micropores are formed by roughening the substrate or punching. It may be.

  The gel-like body 2 is composed of a gel-like material having adhesiveness and vibration absorption. Such a gel-like material has a fluidity limited by a three-dimensional cross-linked structure and can exhibit viscoelastic behavior. For example, it is possible to use adhesive rubber such as soft rubber, polyurethane rubber, or silicone gel. it can. These have a holding force that does not break even with respect to the load of the fixed structure. It has vibration absorption as an elastic body.

  Specifically, even if a furniture / office fixed structure is placed, the shore hardness is 10 so that the gel-like body 2 has a load resistance so that the shape of the gel-like body 2 can be maintained to some extent. It is preferable that it has the above hardness, More preferably, it is about 20-50 Shore hardness.

  At the laminated interface between the gel-like body 2 and the support 1, the gel of the gel-like body 2 is fitted into the concave portion of the uneven surface 1 b, and the convex portion of the uneven surface is fitted into the gel-like body 2. The gel-like body 2 is combined and integrated. Such a laminated interface is achieved by manufacturing as described later.

It is preferable that the bonding force of the lamination interface is larger than the adhesive force of the gel-like body 2 and larger than the engagement force between the engagement surface 1a and the floor or wall surface to be engaged. For example, after a 100 cm ² plate-shaped test piece of a gel-like body is sandwiched between stainless plates and crimped with 200 N, the force required for pulling the stainless plate in the direction opposite to the crimping direction and peeling off the stainless plate is obtained. It preferably has an adhesive strength of 600N to 2500N. More specifically, as shown in FIG. 3, a plate-like test piece of a gel-like body is sandwiched between stainless steel plates, and subjected to pressure bonding by resting for 1 minute under a load of 200 N, and then manufactured by Shimadzu Corporation. When the autograph AGS-5kND (used load cell 5kN) is used and pulled in the direction of the arrow at 200 mm / min, the load when the stainless steel plate is peeled off is preferably 600 N to 2500 N.

Next, the manufacturing method of the fall prevention tool of this invention is demonstrated.
The fall prevention tool of the present invention is obtained by casting a liquid composition containing a monomer, oligomer, or prepolymer as a constituent material of the gel-like body 1 on the uneven surface 1b of the support 1, drying, and crosslinking and curing. Can be manufactured.

  Examples of the liquid composition to be used include a combination of a liquid urethane prepolymer and a curing agent; a combination of a liquid urethane prepolymer and a crosslinking monomer; a combination of an isocyanate oligomer and a polyol; a combination of a liquid silicone and a curing agent; A combination of a liquid rubber and a cross-linking agent is included. If necessary, the composition may further contain a tackifier resin, a crosslinking aid, a deterioration inhibitor, a pigment, a plasticizer, and the like. The composition before curing is liquid and may contain a solvent as necessary.

  After casting the above liquid composition, it is heated and cured as necessary. The liquid composition is cross-linked and cured in a state of flowing into the uneven surface 1b without any gaps, whereby the gel-like body 2 is fixed and integrated with the support 1, and a part of the gel-like body is formed on the uneven surface 1b. Is in the inserted state. Accordingly, the cured gel body 2 can act as an anchor to the unevenness of the uneven surface 1b, so that the adhesive force on the surface of the gel body 2 and the engagement surface 1a are engaged at the lamination interface. A coupling force larger than the engagement force between the target fabric and the like can be ensured.

  The fall prevention tool having the above-described configuration is used by fixing the engaging surface 1a of the support 1 to the floor or wall. Here, the floor suitable for use of the fall prevention tool of the present invention is a floor on which cloths such as carpets, carpets, non-woven fabrics and felts are laid. Particularly preferred are carpets and carpets. In general, carpets and carpets are made by weaving warp yarns that form piles in addition to the warp and weft yarns that make up the ground structure. The cut pile is floating. Therefore, when the furniture overturn prevention tool of the present invention is placed on such a fabric, the pile portion of the carpet and the engaging portion 3 of the engaging surface 1a are engaged and fixed to the carpet or the like.

  A fixed structure is placed on the gel-like body of the fall prevention tool that is engaged and fixed to a carpet or the like. The bottom surface of the fixed structure is adhesively fixed by the adhesive force of the gel-like body. In this way, the structure is indirectly fixed to the floor via the fall prevention tool.

  And with respect to vibrations such as earthquakes, the vibration received from the floor is attenuated by the gel-like body 2, so that the vibrations propagating to the fixed structure can be reduced. Therefore, since the force that the fixed structure moves by vibration is smaller than the moving force that the support receives on the engagement surface, the structure placed on the gel-like body 2 as long as the support is fixed to the floor. There is no movement of the object or even only the structure is peeled off from the gel-like body 2 and falls.

  Furthermore, since the engagement surface 1a of the support 1 and the carpet are engaged, the structure does not fall over unless a force exceeding the engagement force is applied.

  On the other hand, when it is desired to move the structure by changing the interior, the gel-like body 2 may be peeled off from the structure. Since the gel-like body 2 and the furniture are only adhered by the adhesive strength of the gel-like body 2, they can be detached. Moreover, since the engagement surface 1a and the floor are only engaged, it is only necessary to peel off the fall prevention tool so as to release the engagement.

  As described above, the fall prevention device of the present invention can be laid on the floor so as to be detachable, and furniture can also be detachably mounted, so that the interior can be easily changed, Even after the change, the structure and floor are not damaged.

  The fall prevention device of the present invention can be easily fixed to a floor of a fabric such as a carpet or a carpet, etc. Moreover, for strong vibration such as an earthquake, a chase, cabinet, etc. placed on the fall prevention device. By attenuating the vibrations propagating to home and office fixed structures, these structures are prevented from falling. And since these furniture and fall prevention tools can be peeled off without leaving any scratches on the fixed structure, floor, etc., it is useful as a fall prevention tool for fixed structures for homes and offices that can respond to changes in the interior and layout. is there.

It is a schematic cross section of the fixed structure fall prevention tool of one embodiment of the present invention. It is a schematic cross section which shows the other Example of an engagement surface. It is a figure for demonstrating the measuring method of adhesive force.
