  Hereinafter, the present invention will be described based on the illustrated embodiment. FIG. 1 is a perspective view showing an exploded state of the seismic reinforcement bracket according to the basic embodiment of the present invention. As shown in the figure, this seismic reinforcing metal fitting is constituted by an L-shaped main body 10 and a protective cover 20.

  The L-shaped main body portion 10 is configured by bending an elongated metal plate at a right angle near the center. Here, for convenience of explanation, as shown in the figure, the right side surface of the plate-like portion standing vertically is referred to as the first surface 11, and the upper surface of the horizontally disposed plate-like portion is referred to as the second surface 12. The left surface of the vertically standing plate-like portion is called a third surface 13, and the lower surface of the horizontally arranged plate-like portion is called a fourth surface 14. Also, the first surface 11 and the second surface 12 forming 90 ° with each other are referred to as a front surface, and the third surface 13 and the fourth surface 14 forming 270 ° with each other are referred to as a back surface. To.

  The L-shaped main body 10 further includes a rib plate 18 made of a plate having a right triangle shape with one side connected to each of the first surface 11 and the second surface 12. The rib plate 18 is disposed so that both surfaces thereof are perpendicular to the first surface 11 and the second surface 12, and the first surface 11 and the second surface 12 are 90 ° to each other. It serves to reinforce the relationship.

  The back surface of the L-shaped main body 10 is fixed in a state where it is in contact with a wall surface or a top plate of furniture. Fixing is done with screws from the front side. In the embodiment shown here, three through holes H1, H2, H3 are formed in the first surface 11, and three through holes H4, H5, H6 are also formed in the second surface 12. Here, the through holes H1 and H3 are screwing through holes for inserting the screws S1 and S3 into the L-shaped main body portion 10 for fixing to the wall surface, and the through holes H4 and H6 are It is a screwing through hole for inserting screws S4 and S6 into the L-shaped main body 10 in order to fix the furniture to the top plate. The user fixes the L-shaped main body 10 to the wall surface and the top plate of the furniture using these four screws.

  The L-shaped main body 10 fulfills the original function as a seismic reinforcement metal fitting for preventing the furniture from toppling during an earthquake disaster. In other words, since the upper part of the furniture is fixed to the wall surface, the furniture will not fall over in the event of an earthquake. Therefore, it is sufficient to attach the L-shaped main body 10 if it only performs the above function.

  However, the L-shaped main body 10 is a member made of a metal plate, and becomes a factor that impairs the aesthetic appearance when mounted in a room. In addition, if a sufficient surface finish is not performed, touching the hand may cause injury. In the present invention, a protective cover 20 is provided to cope with such a problem.

  As illustrated, the protective cover 20 includes a first plate-like covering portion 21 that covers the first surface 11 of the L-shaped main body 10, a second plate-like covering portion 22 that covers the second surface 12, and Are joined to each other so as to form 90 ° at the end portions, and a side surface covering portion 25 that covers the side surface 15 of the L-shaped main body portion 10 is formed in the peripheral portion. Further, the protective cover 20 is formed with a rib plate accommodating portion 28 for accommodating the rib plate 18 provided in the L-shaped main body portion 10. Accordingly, the L-shaped main body 10 is fitted into the protective cover 25 and is completely accommodated inside the protective cover 25.

  As shown in the figure, the first plate-shaped covering portion 21 is formed with an auxiliary through hole H7 for allowing the screw S2 to pass therethrough, and the second plate-shaped covering portion 22 is provided with an auxiliary penetration for allowing the screw S5 to pass therethrough. A hole H8 is formed. In a state where the L-shaped main body 10 is housed in the protective cover 25, the auxiliary through-hole H7 is aligned with the position of the auxiliary through-hole H2 provided in the L-shaped main body 10 and the auxiliary through-hole H8 is L It arrange | positions so that it may align with the position of the auxiliary | assistant through-hole H5 provided in the character-shaped main-body part 10. FIG.

  In other words, the screw S2 that penetrates both the first plate-shaped covering portion 21 and the L-shaped main body portion 10 in a state where the L-shaped main body portion 10 is fitted and accommodated inside the protective cover 20. First auxiliary through holes H7 and H2 are formed to pass through, and a second auxiliary for passing the screw S5 penetrating both the second plate-like covering portion 22 and the L-shaped main body portion 10 is formed. The through holes H8 and H5 are formed. The tip of the screw S2 is inserted through the through hole H2 and fixed to the wall surface, and the tip of the screw S5 is inserted through the through hole H5 and fixed to the top plate of the furniture.

  2 is a side sectional view showing a state in which furniture is fixed to a wall surface using the seismic reinforcing metal fitting shown in FIG. 1, and FIG. 3 is a front sectional view taken along a cutting line AA ′ shown in FIG. . The third surface 13 of the L-shaped main body 10 is firmly fixed by screws S1 and S3 in a state where the third surface 13 is in contact with the wall surface 30. The fourth surface 14 of the L-shaped main body 10 is firmly fixed by screws S4 and S6 in contact with the top surface of the furniture top plate 40. On the other hand, the first plate-like covering portion 21 is arranged at a position covering the first surface 11 of the L-shaped main body portion 10 and is fixed to the wall surface 30 by screws S2, and the second plate-like covering portion 22 is provided. Is arranged at a position covering the second surface 12 of the L-shaped main body 10 and is fixed to the top plate 40 of the furniture by screws S5.

  Here, the screws S1, S3, S4, and S6 need to have sufficient strength to withstand the load for fixing the furniture 40 to the wall surface 30, whereas the screws S2 and S5 have the load of the protective cover 20. It is enough if there is enough strength to support it. In the case of this embodiment, as shown in FIG. 2, flat screws with flat heads are used as the screws S2 and S5, and the auxiliary through holes H7 and H8 are tapered to accommodate the heads of the flat screws. Therefore, in a state where the screws S2 and S5 are fixed, the outer surface of the protective cover 20 and the head of the flat screw are on the same surface. For this reason, the appearance of the protective cover 20 is excellent in design.

  In a state where the protective cover 20 is attached, the L-shaped main body portion 10 is completely accommodated inside the protective cover 20 and includes an L-shape including screws S1, S3, S4 and S6. The surface of the main body 10 is not exposed to the outside. The protective cover 20 can be made of a material that does not feel uncomfortable even if it is placed indoors, such as synthetic resin or wood having high design properties, so that the aesthetic appearance is not impaired. Moreover, since it is not metal, it will not be injured even if it touches, and safety can also be ensured.

  As mentioned above, although this invention was demonstrated based on embodiment shown in figure, this invention is not limited to the said embodiment. For example, in the above example, the L-shaped main body portion 10 is provided with the rib plate 18 for reinforcement. However, the L-shaped main body portion 10 is provided with rigidity capable of sufficiently maintaining the basic structure. In this case, the rib plate 18 can be omitted. Of course, when the rib plate 18 is omitted, the rib plate housing portion 28 on the protective cover 20 side can also be omitted.

  Moreover, in the above example, in order to fix using the six screws S1 to S6, the L-shaped main body portion 10 is provided with six through holes H1 to H6, and the protective cover 20 has two through holes H7. , H8 are shown, but the number of screws used for fixing is arbitrary, and as many through holes as necessary to pass the screws may be provided.

  Furthermore, in the above example, two screws S2 and S5 are used to fix the protective cover 20, but it is not always necessary to use screws to fix the protective cover 20. For example, the protective cover 20 is made of a material that generates elastic deformation such as synthetic resin or rubber, and is fitted to the side surface 15 of the L-shaped main body 10 and the inner surface of the side surface covering portion 25 of the protective cover 20. If a locking structure to be combined is formed, the protective cover 20 can be fitted and fixed to the L-shaped main body 10 using its elastic deformation. In this case, there is no need to provide screws S2 and S5 and through holes for these.

  Of course, fixing by screws S2 and S5 may be used in combination while adopting the locking structure. Further, the protective cover 20 may be fixed to the L-shaped main body 10 with an adhesive without performing the locking structure or the screws S2 and S5.
