JP-A-8-308660 JP-A-9-10055

  Since the conventional furniture overturn prevention device connects the furniture holding member and the furniture by screws, it is inevitable that a screw hole is opened on the side or top of the furniture. There are many people who feel strong resistance to scratching screws such as screw holes on furniture that they are attached to, and this may hinder the spread of fall prevention devices.

  Further, the connecting means by screwing may be easily loosened or pulled out by vibration during an earthquake.

  Furthermore, for steel furniture (lockers, cabinets, etc.) frequently used in business offices and the like, it is not realistic because it cannot use a connecting means for fixing the furniture holding member to the side surface or the top surface. .

  The present invention has been made in view of the circumstances as described above, and provides a furniture overturn prevention device that can hold furniture firmly and firmly without damaging the side or top surface of the furniture. Is a solution issue.

  In order to achieve the above-mentioned object, in the furniture overturn prevention device according to claim 1 of the present invention, a rail fixed to a wall, and furniture that can be moved along the rail and fixed at an arbitrary position. In a furniture overturn prevention device comprising a holding member, the furniture holding member has a flat contact surface portion applied to a side surface or top surface of the furniture, and an adhesive sheet is adhered to the contact surface portion. It is characterized by that.

  According to this configuration, the contact surface portion of the furniture holding member comes into surface contact with the side surface or the top surface of the furniture via the adhesive sheet adhered to the flat surface. The furniture can be firmly held by the adhesive force and frictional force of the adhesive sheet without damaging the surface. In addition, the flat contact surface portion is preferably in surface contact not only with the wooden furniture but also with the steel furniture, so that the flat abutting surface portion can be firmly held against the steel furniture.

  Examples of the pressure-sensitive adhesive sheet include natural rubber and various synthetic rubbers, asphalt-based, acrylic-based, urethane-based, styrene-based, vinyl-based thermoplastic elastomers, soft resins, and other organic polymer compounds. A material that has viscosity and moderate elasticity or flexibility and generates a sufficient frictional force with furniture can be suitably used. In particular, if a viscoelastic body having a high damping action is used, an excellent damping effect can be obtained, which is even more desirable.

  The pressure-sensitive adhesive sheet is a combination of different types of materials, such as attaching a viscous material as described above to a thin plate-like base material made of a suitable flexible material, or a cushioning material made of a foamable resin or the like. Alternatively, it may be formed by stacking. Further, the pressure-sensitive adhesive sheet may be adhered to the contact surface portion with its own adhesive force, or may be structured to be adhered to the contact surface portion via another adhesive or the like.

  The thickness of the pressure-sensitive adhesive sheet adhered to the abutting surface is approximately several mm in order to obtain an appropriate vibration absorbing property. In order to obtain a stable holding force, it is preferable that the contact surface portion has a size of about several cm square or more.

  Note that the present invention does not strictly specify the viscosity (viscosity), elastic modulus, etc. of the material as described above, and does not particularly treat the viscous body, the elastic body, the viscoelastic body, etc. .

  The furniture overturn prevention device according to claim 2 of the present invention is characterized in that a suction cup is attached to the contact surface portion of the furniture holding member instead of the adhesive sheet.

  According to this structure, the contact surface part of a furniture holding member adsorb | sucks to the side surface or top | upper surface of furniture via a suction cup. By using the suction cup, it is possible to hold the furniture firmly without damaging the furniture, as in the first aspect of the invention.

  In the furniture overturn prevention device according to claim 3 of the present invention, the contact surface portion of the furniture holding member is urged in the contact direction to the furniture by a spring or other elastic material. Is.

  According to this configuration, even when vibration due to an earthquake or the like acts between the furniture holding member and the furniture, the contact surface portion follows the vibration and is pressed against the furniture, so that a stable holding state is maintained. As the elastic material, various springs according to the form and structure of the furniture holding member such as a coil spring, a leaf spring, a disc spring, and a torsion bar can be used. In addition to the spring, for example, urethane or other foamable resin can be used.

  According to a fourth aspect of the present invention, there is provided a furniture overturn prevention device that specifies the type of furniture held by the furniture holding member described above, wherein at least two furniture holding members are attached to a substantially horizontally fixed rail. Further, the contact surface portions of the furniture holding members face each other and sandwich both side surfaces of the furniture.

  Since this configuration has a degree of freedom in the width direction with respect to the position of the furniture holding member, it can flexibly correspond to the position and size of the furniture. Further, since the furniture is clamped from both sides by the furniture holding member, the most stable holding force is exhibited not only in the horizontal vibration but also in the vertical and forward vibrations. This prevents the drawer from falling off.

  According to a fifth aspect of the present invention, there is provided a furniture overturn prevention device that specifies another form of furniture holding by the above-mentioned furniture holding member, and the furniture is mounted on a rail that is fixed substantially horizontally along the top surface of the furniture. A holding member is attached, and the contact surface portion of the furniture holding member presses the top surface of the furniture downward.

  This configuration is suitable, for example, when furniture of the same height is juxtaposed. By pressing the top surface of the furniture from above with the furniture holding member, a good holding force is exhibited against vibrations in the left and right directions and the front and rear directions in addition to the vibrations in the vertical direction. Further, when arranging a plurality of furniture, the furniture holding member does not have to be sandwiched between adjacent furniture, so that the furniture can be brought into contact with each other without a gap.

  When the top surface of the furniture is pressed by the furniture holding member, an appropriate height is provided between the furniture holding member and the rail so that the height of the furniture holding member can be finely adjusted according to the height of the furniture. It is also preferable to provide adjusting means.

  In the furniture overturn prevention device according to claim 6 of the present invention, the furniture holding member mounting structure with respect to the rail is specified, and the rail is substantially provided with a lip portion facing the opening on the front side. The furniture holding member is attached to the rail by a nut member loosely inserted into the rail groove and a bolt member fastened to the nut member from the front side. .

  According to this configuration, by loosening the bolt member, the furniture holding member can be smoothly slid along the rail. Therefore, by tightening the bolt member, the furniture holding member can be firmly placed at an arbitrary position on the rail. Can be fixed. Moreover, since the vibration which acts on furniture is received by the whole rail via a furniture holding member, the high earthquake resistance strength is exhibited as the whole apparatus.

  In this configuration, it is desirable that a rotation stopper for preventing the rotation of the nut member is provided in the groove of the rail. The detent can be configured by making the substantial groove width of the rail smaller than the maximum width of the nut member. Thereby, the fastening operation | work of the bolt member at the time of positioning of a furniture holding member becomes easy. Furthermore, if the bolt member is a butterfly bolt, it is possible to fasten without using a tool, and the workability is further improved.

  In the furniture overturn prevention device of the present invention configured as described above, an adhesive sheet or a suction cup is attached to the contact surface portion of the furniture holding member attached to the rail, and the side surface or ceiling of the furniture is interposed via the adhesive sheet or suction cup. Since the surface is pressed, the furniture can be held firmly and firmly without damaging the screw holes or the like.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 show a furniture overturn prevention device according to a first embodiment of the present invention, and FIGS. 4 and 5 show a furniture holding form by the overturn prevention device.

  The fall prevention device 1 of the present invention is mainly composed of a rail 2 fixed to a wall and furniture holding members 3 and 3 attached to the rail 2.

  The rail 2 according to the illustrated embodiment is a long or fixed member made of, for example, an aluminum extrusion mold material, and the upper and lower edges of the back plate portion 21 corresponding to a web are integrally provided with pressing portions 22 and 22 corresponding to flanges. The cross-sectional shape of the groove shape formed in this is comprised. The protruding portions 22 and 22 are extended with lip portions 23 and 23 facing each other with an opening on the front side. A space surrounded by the back plate portion 21 and the lip portion 23 serves as a guide groove for holding the furniture holding member 3 movably.

  A nut member 42 described later is loosely inserted into the guide groove. A rotation stopper for preventing the nut member 42 from idling is provided inside the guide groove. The anti-rotation in the illustrated embodiment includes two upper and lower step portions 24 and 24 formed on the front surface of the back plate portion 21, and two upper and lower protrusions 25 and 25 formed on the rear surfaces of the lip portions 23 and 23. It is constituted by.

  The protruding portion 22 positioned outside the guide groove secures the bending rigidity of the rail 2 by its thickness and also serves as a screw stopper for fixing the rail 2 to the wall W. Therefore, countersunk holes 26 are formed in the protruding portion 22 at appropriate intervals in the length direction. The rail 2 is fixed to the wall W by driving a screw (not shown) inserted into the countersink 26 into an appropriate wall base material. The rail 2 may be fixed in a state of being embedded in the wall W so that the front surface thereof is flush with the wall W.

  Further, in the illustrated form, in order to save the material required for molding while ensuring the strength of the rail 2, on the back side of the back plate portion 21 and the inside of the protruding portion 22, 28 is formed.

  The furniture holding member 3 is made of a metal plate bent in a substantially L shape, and one piece is a rail mounting piece 31 and the other piece perpendicular to the piece is a furniture holding piece 32.

  The furniture holding member 3 is attached to the rail 2 via a bolt member 41 and a nut member 42. In the illustrated embodiment, a hexagonal nut is used as the nut member 42, and the nut member 42 is loosely inserted into the guide groove of the rail 2. A butterfly bolt is used as the bolt member 41. The shaft portion of the bolt member 41 is inserted from the front side into a bolt hole 33 formed in the rail attachment piece 31 and is further screwed to the nut member 42 with the lip portion 23 of the rail 2 interposed therebetween. Reference numeral 43 in FIGS. 1 to 3 is a washer interposed between the head of the bolt member 41 and the rail mounting piece 31.

  By constructing the attachment structure of the furniture holding member 3 to the rail 2 in this way, when the bolt member 41 is loosened, the furniture holding member 3 can be moved to an arbitrary position along the rail 2. When the bolt member 41 is tightened, the furniture holding member 3 can be fixed to the rail 2.

  Further, in the above-described detent formed in the guide groove of the rail 2, the vertical distance between the step portions 24, 24 and the vertical distance between the protrusions 25, 25 are slightly larger than the two-surface width of the nut member 42, And since it is set so that it may become smaller than the diagonal distance of this nut member 42, the said nut member 42 interferes in this rotation stop, and the attitude | position in a guide groove is restrained.

  In a state where the furniture holding member 3 is attached to the rail 2, the furniture pressing piece 32 is held in a posture orthogonal to the front surface of the rail 2. The furniture pressing piece 32 has a flat contact surface portion on the opposite side to the extending direction of the rail mounting piece 31, and an adhesive sheet 34 is adhered to the contact surface portion.

  The pressure-sensitive adhesive sheet 34 is formed, for example, by forming a synthetic rubber having viscosity into a plate shape having a thickness of about several millimeters. The pressure-sensitive adhesive sheet 34 is attached to the substantially entire surface of the contact surface portion of the furniture pressing piece 32 or a range slightly smaller than that. The furniture F overturn prevention device 1 according to the present invention is such that the pressure-sensitive adhesive sheet 34 adhered to the flat contact surface portion is bonded to the side surface or the top surface of the furniture F, thereby damaging the furniture F. Without holding, it can be held firmly.

  The pressure-sensitive adhesive sheet 34 includes, for example, natural rubber and various synthetic rubbers, asphalt-based, acrylic-based, urethane-based, styrene-based, vinyl-based thermoplastic elastomers, soft resins, and other organic polymer compounds. A material having a sufficient viscosity and moderate elasticity or flexibility and generating sufficient frictional force with the furniture F can be suitably used. In particular, if a viscoelastic body having a high damping action is used, an extremely excellent damping effect can be obtained, which is even more desirable.

  The pressure-sensitive adhesive sheet 34 may be of different types, for example, by adhering the viscous material as described above to a thin plate-like base material made of an appropriate flexible material or a cushioning material made of foamable resin. It may be formed by combining or laminating materials. The pressure-sensitive adhesive sheet 34 may be adhered to the contact surface portion with its own adhesive force, or may be bonded to the contact surface portion via another adhesive or the like. The surface of the pressure-sensitive adhesive sheet 34 may be subjected to uneven processing for increasing the frictional force with the furniture F.

  The furniture holding form shown in FIGS. 4 and 5 is the most basic and stable holding force. The rail 2 is fixed substantially horizontally to the wall W, and at least two furniture holding members 3 are attached to the rail 2. The furniture holding member 3 faces each other with the furniture pressing pieces 32 in the vertical direction, and holds both side surfaces of the furniture F from the left and right.

  Since this holding form has a degree of freedom in the width direction with respect to the position of the furniture holding member 3, it can flexibly correspond to the arrangement and size of the furniture F. In this case, since the furniture F is clamped from both sides, the furniture F is stably held not only in the horizontal vibration but also in the vertical and front-back vibrations.

  Several examples of other furniture holding forms by the fall prevention device 1 are shown in FIGS.

  When the height and weight of the furniture F are large, as shown in FIG. 6, two rails 2 are arranged at different heights in the vertical direction, and the furniture holding members 3, 3 are arranged on each rail 2, 2. They may be attached one by one so as to sandwich the vicinity of the upper portion and the middle portion of the furniture F.

  In addition, as shown in FIG. 7, instead of fixing one long rail 2 over the width of the furniture F, short rails 2 and 2 are attached at positions overlapping the left and right side surfaces of the furniture F, respectively. The furniture holding members 3 and 3 may be attached to the rails 2 and 2. Furthermore, in this case, the heights of the left and right rails 2 and 2 may be slightly different. Depending on the underlying structure of the wall W, etc., it may be difficult to continuously fix the single long rail 2 to the wall W. Under such conditions, a holding form as illustrated is also effective. .

  In addition, as shown in FIG. 8, when the furniture F is arranged at the corner of the room and one side surface of the furniture F is in contact with one wall Wb, only the other side surface of the furniture F is a single piece. You may hold | maintain with the furniture holding member 3 so that it may hold | suppress toward said one wall Wb.

  9 and 10 is a form in which the top surface of the furniture F is pressed from above by the furniture holding member 3. The rail 2 is fixed substantially horizontally along the top surface of the furniture F at a position slightly higher than the top surface. An appropriate number of furniture holding members 3 corresponding to the width of the furniture F are attached to the rail 2. The furniture holding member 3 is pressed downward on the top surface of the furniture F with the furniture pressing piece 32 in a horizontal position, and sandwiches the furniture F between the furniture holding member 3 and the floor surface. According to this holding mode, a good holding force is exhibited against vibrations in the left-right direction and the front-rear direction in addition to the vibrations in the vertical direction.

  This holding form is particularly suitable for an aspect in which a plurality of furniture F having the same height are juxtaposed. Further, when arranging a plurality of furniture F, the furniture holding member 3 does not have to be sandwiched between the adjacent furniture F, which is also suitable for arranging furniture without gaps.

  In this holding form, the top surface of the furniture F and the height of the rail 2 are inconsistent due to dimensional errors of the furniture F itself, unevenness of the floor surface, deformation of the floor finish, inclination at the time of placement, and the like. There is a risk of consistency. Therefore, as shown in FIG. 11, as a height adjusting means of the furniture holding member 3, for example, a configuration in which the bolt hole 33 formed in the rail attachment piece 31 is formed in a long hole shape extending in the vertical direction is adopted. Also good.

  The form shown in FIG. 12 gives the furniture holding member 3 the freedom degree of the up-down direction by fixing the rail 2 vertically. The furniture holding member 3 is attached to the rail 2 with the furniture holding piece 32 horizontal, and presses the top surface of the furniture F downward to sandwich the furniture F with the floor surface. Also in this holding mode, as in the holding mode shown in FIGS. 9 and 10, in addition to the vertical vibration, a good holding force with respect to the horizontal and front-back vibrations is exhibited.

  FIG. 13 shows a second embodiment of the furniture holding member 3. The furniture holding member 3 according to this embodiment has a substantially L-shape including a rail attachment piece 31 and a furniture presser piece 32, and the rail attachment piece 31 is attached to the rail 2 via a bolt member 41 and a nut member 42. This point is common to the furniture holding member 3 according to the first embodiment described above.

  However, a suction cup 36 is attached to the contact surface portion of the furniture pressing piece 32 instead of the adhesive sheet 34. The suction cup 36 is adsorbed to the furniture F by pressure contact with the side surface or the top surface of the furniture F, and holds the furniture F firmly without damaging it.

  In this configuration, it is only necessary that the suction surface of the suction cup 36 is held so as to be orthogonal to the rail mounting piece 31, and the contact surface portion of the furniture pressing piece 32 does not need to be flat. Further, the suction cups 36 may be mounted in a plurality of small diameters.

  FIG. 14 shows a third embodiment of the furniture holding member 3. The furniture holding member 3 according to this embodiment also has a substantially L-shaped shape including a rail attachment piece 31 and a furniture presser piece 32, and the rail attachment piece 31 is attached to the rail 2 via a bolt member 41 and a nut member 42. This point is common to the furniture holding member 3 according to the first embodiment described above.

  A contact plate 38 formed separately from the furniture pressing piece 32 is attached. The contact plate 38 has a flat contact surface portion, and a thin adhesive sheet 34 is stuck on the surface thereof. The contact plate 38 is attached substantially in parallel to the furniture pressing piece 32 via an elastic material 39 made of a spring or the like, and is urged in the contact direction with the furniture F by the elastic material 39.

  According to this configuration, even when vibration due to an earthquake or the like acts between the furniture holding member 3 and the furniture F, the contact plate 38 is pressed against the furniture F following the vibration by the action of the elastic member 39, A stable holding state is maintained. As the type of the elastic member 39 that urges the contact plate 38, various springs according to the form and structure of the furniture holding member 3, such as a coil spring, a leaf spring, a disc spring, and a torsion bar, can be used. In addition to the spring, for example, rubber, urethane, other foamable resins, or the like, or known elastic materials similar to these can be widely used.
