It bites in and is fixedly attached to the panel P1. Further, when the hole H2 of the interior panel P2 having a small thickness is targeted, the hooking member 12 is similarly press-fitted into the hole H2 from the indoor side, and the hooking member 12 is passed through the hole H2 when the hooking member 12 exceeds the hole H2. By simply twisting the main body 11 in the direction of deepening the threaded shaft 2 to the retaining member 12, the pawls 6 of the retaining pieces 5 that have increased the degree of opening due to the disappearance of the pressure when the retaining member 12 is press-fitted. The hole H2 is inserted into and fixed to the panel P2 in such a manner that the panel P2 is sandwiched between the shielding plate 1 and the hooking member 12 of the main body 11 by biting into the peripheral edge of the panel rear surface side.

  Thus, the hole closing device 10 mounted and fixed in the holes H1 and H2 of the interior panels P1 and P2 is shaped so as to conceal the holes H1 and H2 by the flat shielding plate 1, so that the interior side of the panels P1 and P2 is inside. While the appearance is improved, when a force in the pulling direction is applied to the main body 10, the force acts in a direction to increase the biting of the pawls 6. Therefore, there is no concern of extracting from the holes H1 and H2. Further, the hole closing device 10 includes a main body 11 in which the screw shaft 2 is erected on the shielding plate 1 and a latching member 12 provided with the screw hole 3, and is very simple in structure, so that it is inexpensive. Can be produced.

  According to the invention of claim 2, in the hole closing device 10 described above, since the hooking member 12 has the four hooking pieces 5 equally arranged with a phase difference of 90 degrees, the holes H1 of the interior panels P1, P2 are provided. , Because the hooking member 12 is less likely to be inclined when press-fitted into H2, and many claws 6 bite evenly in the circumferential direction with respect to the inner peripheral surface of the hole H1 and the peripheral edge of the rear surface side of the hole H2. , The mounting state becomes stronger and more stable.

  According to the invention of claim 3, in the hole closing device 10, each latching piece 5 of the latching member 12 bites into the interior panel P <b> 1, P <b> 2 side by the pair of claws 6, 6 at the tip. Therefore, the attachment state to the panels P1 and P2 becomes stronger.

  According to the invention of claim 4, in the hole closing device 10 described above, each latching piece 5 of the latching member 12 is inclined at an angle of 20 to 45 degrees with respect to the axis of the screw hole 3. The pawls 6 are good to bite the interior panels P1 and P2, and the latching pieces 5 are not easily bent by the force in the pulling direction, and the attachment strength to the panels P1 and P2 increases accordingly.

  According to the invention of claim 5, in the hole closing device 10 described above, since the latching member 12 is made of a single metal plate, its manufacture is easy and the material cost can be reduced.

  Hereinafter, a hole closing tool for an interior panel according to an embodiment of the present invention will be specifically described with reference to the drawings. 1 is an exploded perspective view of the hole closing device 10, FIG. 2 is a front view and a plan view of the hole closing device 10, and FIG. 3 shows a mounting operation of the hole closing device 10 to the hole H1 of the thick interior panel P1. FIG. 4 is a longitudinal side view showing a mounting operation of the hole closing tool 10 to the hole H2 of the interior panel P2 having a small thickness.

  As shown in FIGS. 1 and 2 (a) and 2 (b), the hole closing device 10 has a screw shaft 2 standing vertically by stud welding at the center of one surface of a disk-shaped metal shielding plate 1. And a latching member 12 having a screw hole 3 screwed into the screw shaft 2 of the main body 11.

  The latching member 12 is formed of a single metal plate, and is screwed so that the latching pieces 5 have a distance from the tip side to each other from the four sides of the square base 4 having the screw hole 3 at the center. It projects in an inclined direction with respect to the axis of the hole 3. A pair of claws 6 and 6 are formed by V-cuts at the tips of the respective retaining pieces 5. The screw hole 3 is obtained by burring the perforated portion of the base 4 and engraving a female screw on the inner periphery of the raised peripheral edge.

  Therefore, the latching piece 5 of the latching member 12 is an interior panel that applies the distance between the tips of the opposing latching pieces 5, 5 (= the diameter of the circumscribed circle with respect to the tips of all the latching pieces 5). It is necessary to set it slightly larger than the diameter of the hole. Therefore, when the distance (diameter of the circumscribed circle) is insufficient with respect to the hole diameter to be applied, the opening of the latching pieces 5 may be increased with pliers or the like.

  As shown in the figure, this hole closing device 10 is in a state in which the screw shaft 2 of the main body 11 is screwed into the screw hole 3 of the latching member 12 with the front end side of the latching pieces 5. Although it is used, there are two ways to use depending on the thickness of the interior panel to be applied.

  First, as shown in FIG. 3, when closing the hole H1 of the thick interior panel P1 such as a plaster board, the latching member 12 screwed into the main body 11 as shown in FIG. It is only necessary to press-fit into the hole H1 by using the bending of the stopper 5 due to the material elasticity, and push it to the position where the periphery of the shielding plate 1 of the main body 11 contacts the surface of the panel P1 as shown in FIG. . By this one-touch operation, the hooking member 12 is fitted and fixed to the panel P1 as a whole of the hole closing device 10 because the claws 6 of the hooking pieces 5 bite into the inner peripheral surface of the hole H1 and cannot be pulled out. The hole H1 is concealed by the shielding plate 1 and the appearance of the indoor side of the panel P1 is improved. In addition, when a force in the pulling direction is applied to the main body 10 in this mounted state, the force acts in a direction to increase the biting of the claws 6 in the retaining member 12 into the inner periphery of the hole H1, so that the hole closing device There is no concern that 10 will fall out of the hole H1.

  On the other hand, when closing the hole H2 of the interior panel P2 having a small thickness as shown in FIG. 4, the latching member 12 is press-fitted into the hole H2 in the same manner as shown in FIGS. The entire latch member 12 is pushed over the hole H2 so as to come to the back side of the panel P2 as shown in FIG. As a result, the latching pieces 5 of the latching member 12 released from the pressure at the time of press-fitting return to the original open state by the elastic restoring force, and the distance between the tips (diameter of the circumscribed circle) becomes larger than the hole diameter. Then, by twisting the main body 11 in a direction that deepens the screw shaft 2 to be engaged with the latching member 12, the claws 6 of the latching pieces 5 of the latching member 12 become the panel back side of the hole H2. The hole closing device 10 is attached and fixed to the panel P2 in such a manner that the panel P2 is sandwiched between the shielding plate 1 and the latching member 12 of the main body 11 as shown in FIG.

  Even in the state where the panel P2 is mounted in the hole H2, the hole H2 is concealed by the shielding plate 1, so that the appearance of the panel P2 on the indoor side is improved and the force in the pulling direction applied to the main body 10 is also applied. Since the nail | claw 6 ... in the latching member 12 acts in the direction which strengthens biting with respect to the periphery of the panel back surface side of the hole H2, there is no fear that the said hole closing tool 10 falls out from the hole H2.

  Further, the hole closing device 10 includes a main body 11 in which the screw shaft 2 is erected on the shielding plate 1 and a latching member 12 provided with the screw hole 3, and is very simple in structure, so that it is inexpensive. Can be produced. In particular, if the latching member 12 is formed from a single metal plate as in the embodiment, its manufacture is easy and material costs are low.

  In the present invention, the latching member 12 may be configured such that a plurality of latching pieces 5 are evenly arranged around the base 4 and the three latching pieces 5 are equally arranged with a phase difference of 120 degrees. In addition, a configuration in which two hooking pieces 5 are arranged to face each other with the base 4 interposed therebetween is also included. However, in the configuration including the four retaining pieces 5 as in the embodiment, the retaining member 12 is less likely to be inclined when being press-fitted into the holes H1, H2 of the interior panels P1, P2, and the inside of the hole H1. Since many of the claws 6 bite evenly in the circumferential direction with respect to the peripheral surface and the peripheral edge of the hole H2 on the back side of the panel, there is an advantage that the hole closing device 10 as a whole is more firmly and stably attached. .

  Further, the present invention includes a configuration in which each latching piece 5 of the latching member 12 has only one claw 6 at the tip, but each latching piece 5 has a pair of claws 6 at the tip as in the above embodiment. , 6, the biting to the interior panels P1, P2 side is remarkably improved, so that the attachment state of the hole closing device 10 to the panels P1, P2 becomes stronger.

  Note that the inclination of each latching piece 5 in the latching member 12 is not particularly limited, and it is assumed that the opening is changed with pliers or the like corresponding to the hole diameter of the interior panel to be applied. An angle range of 15 to 45 degrees with respect to the axis is preferable. That is, when the inclination angle is less than 15 degrees, the claws 6 are difficult to bite against the interior panels P1 and P2 side. Conversely, when the inclination angle exceeds 45 degrees, the overhang in the lateral direction with respect to the screw shaft 2 increases. When the force in the extraction direction is applied, it becomes easy to bend.

  On the other hand, the shape of the shielding plate 1 in the main body 11 is not limited to a circle as in the embodiment, and various shapes such as a polygon and an ellipse can be adopted. Also, the screw shaft 2 can be set in various lengths and thicknesses, and the threaded portion does not need to extend over the entire length. For example, about 1/3 to 1/2 from the distal end side may be used as the threaded portion.

It is a perspective view which shows the hole closing tool of the interior panel which concerns on one Embodiment of this invention in the isolation | separation state of a main body and a latching member. The hole closing tool is shown in a connected state of the main body and the latch member, (a) is a front view, and (b) is a plan view. The attachment operation of the hole closing device with respect to the hole of a thick interior panel is shown, (a) is a longitudinal side view before attachment, and (b) is a longitudinal side view after attachment. It is a vertical side view which shows the attachment operation of the hole closing tool with respect to the hole of an interior panel with small thickness in steps of (a)-(d).
