Description of the invention (4) Insert the lower side of the surface of foot 11 and set The closer to the inclined state the head 1 is from the insertion foot 11, and the potential spring is pressed so that the fastener piece 31 is separated from the insertion foot 11. Figs. 8, 9 and 10 are explanatory diagrams showing examples of use of the plate fasteners shown in Figs. 1 to 7. In Fig. 10, B indicates a plate to be mounted, and is provided with, for example, a circular mounting plate and an insertion hole C having a larger diameter than the mounting hole b. The following T1 installs the plate. First, as shown in FIG. 8, the center of the insertion hole b of the plate B to be installed and the center of the insertion hole cM of the plate C are aligned and overlapped. When the front end side is pushed into the mounting hole b from the insertion hole c side, the engaging protrusions 12, 33 are pushed by the peripheral edge of the mounting hole b. The elasticity of the hinge portion 21 causes the fastening piece 31 to approach the insertion foot 11 When the direction is swung, the engaging protrusion 33 also enters the mounting hole b in order from the lower side to the upper side. Therefore, the insertion leg portion 11 and the engaging piece 31 can be inserted into the mounting hole b. At this time, the elastic piece 41 is pressed by the engaging piece 31, and as shown in Fig. 9, the elastic piece 41 is bent to be close to the insertion leg 11 side. In this way, when the head 1 abuts the mounting plate C, the insertion leg 11 and the fastening piece 31 cannot be inserted into the two holes b, c, and the fastening piece 31 is formed by the elasticity of the hinge portion 21 and the elastic piece 41. Swing in a direction away from the insertion of the foot 11, since the buckling protrusions 1 2 and 1 3 corresponding to the total thickness of the two plates B and C are fastened to the plate B to be mounted, therefore, the mounting plate C can be installed and Fixed to the plate to be installed (please read the precautions on the back before filling this page)

Description of the invention (5) As mentioned above, according to the invention In the first embodiment, since the insertion leg portion 11 serves as a reference, the elasticity of the M hinge portion 21 causes the fastening piece 31 to swing away from the insertion leg portion 11 and engages the engagement protrusions 12, 33 to the plate to be mounted. B. Therefore, even if the diameter of the mounting hole b is different, the engaging protrusions 12, 33 can be engaged with the plate B to be mounted. Since the insertion leg 11 is used as a reference, the fastening protrusion 12M is fastened to the mounted plate B in a state of being orthogonal, and the fastening protrusion 33 can also be fastened to the mounted plate B in an inclined shape, which can be obtained reliably. Set installation force. Moreover, since the elastic piece 41 is provided, since the fastening piece 31 is stored in a direction away from the insertion leg portion 11, the fastening protrusion 33 can also be reliably fastened to the plate B to be mounted, and the installation can be further increased. power. Moreover, since the plurality of engaging protrusions 12, 33 are provided, even if the total thickness of the two plates B and C is different, the plate fastener A of the first embodiment can be used. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (read the precautions on the back of the first cabinet and fill in this page). Set the insertion foot 11 at a position deviated from the center of the head 1. The hinge portion 2 1 near the center of the head 1 is provided with a buckle piece 3 1. Therefore, even if there is only one piece in the state of being installed in the mounting hole b, the center of the head 1 can be approximately the same as the center of the mounting hole b. . Fig. 11 is a cross-sectional view showing a state in which the plate fastener of the second embodiment of the present invention is engaged with the plate to be attached, and the same symbols as those in Figs. 1 to 10 are attached with the same symbols, and description thereof is omitted. The difference between the plate fastener of the second embodiment and the plate fastener A of the first embodiment is that one buckle protrusion 12, 33 is provided respectively. This paper size applies the Chinese National Standard (CNS) A4 specification (210X2.97 mm) 5 310074 A7 B7 V. Description of the invention (6) Thus, when there are one fastening protrusions 1 2 and 3 3, due to the two sheet B The total thickness of C and C can be used only when it is constant. Therefore, in addition to the effect that the total thickness of the two plates B and C of the first embodiment is different, the other effects can be used as well as the first embodiment. . FIG. 12 is a bottom view showing a plate fastener of a third embodiment of the present invention; FIG. 13 is a perspective view showing a state where the plate fastener of the third embodiment of the present invention is reversed, and FIG. The same or corresponding parts to Fig. 11 are denoted by the same symbols, and descriptions thereof are omitted. The difference between the plate fastener A of the third embodiment and the plate fastener A of the first embodiment is that the insertion leg 11 perpendicularly positioned at a position deviating from the center of the inside of the head 1 is a triangular columnar point, and the corresponding On the other side of the insertion leg 11, a hinge part 21, a buckle piece 31 and an elastic piece 41 are provided. In this way, when two sets of the hinge part 21, the fastening piece 31, and the elastic piece 41 are provided, except that the same effect as that of the first embodiment can be obtained, since two sets of the hinge part 21 are provided, the fastening pieces 31 and The group of the elastic pieces 41 can further increase the mounting force. Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). In each of the above-mentioned embodiments, the elastic H41 is set on the insertion foot 1 1, but the elastic sheet 4 1 is set on The same effect can also be obtained with the fastening piece 3 1. Moreover, in each embodiment, the elastic sheet 41 is provided, but this elastic sheet 41 is not necessarily required. Further, in the third embodiment, similarly to the second solid pickled embodiment, it is also possible to provide a state in which one of the engaging projections 12, 33 is provided. In addition, the installation plate C is only described as a plate plus M. However, although the installation plate C is plate-shaped, even if it is a sound-absorbing material, carpet, etc., of course, the Chinese paper standard (CNS) Α4 standard (210 X 297 mm) 6 310074 A7 B7 'V. Description of the invention (7) Installation. [Effects of the Invention] As described above, according to the present invention, since the insertion foot is used as a reference, the buckle is rotated by the elasticity of the hinge portion toward the direction from the insertion foot, and the buckle is provided on the insertion foot and the buckle. Since the engaging protrusions are fastened to the plate to be mounted, even if the mounting holes are different, each of the locking protrusions can be fastened to the plate to be mounted. In addition, the foot is used as a reference. Therefore, the fastening protrusions inserted into the legs can be reliably engaged with the plate to be mounted to obtain a predetermined installation force, and the fastening protrusions of the fastening pieces can also be buckled to the plate to be mounted at an angle. The ground gets the set installation power. Moreover, since the elastic piece is provided, since the buckle piece constitutes a potential-accumulating spring to be pushed away from the insertion foot, the buckle protrusion of the buckle piece can also be reliably buckled to the plate to be mounted, which can further increase the size. Install power. Moreover, since a plurality of engaging protrusions are provided, even if the total thickness of the member to be mounted and the mounting plate material are different, a plate fastening device can be used.
