Abstract

(57) [Abstract] [Purpose] The hole b on the wall a that is no longer needed can be very simply
In addition, it was made possible to surely close it. A block plate 3 larger than a hole b to be closed is loosely fitted to a bolt 1 of an appropriate length having a large diameter head 2 at one end and held by the large diameter head 2, and the width is smaller than the hole b. , Hole b
Made of an elastic metal material with a rectangular shape longer than
The bolt 1 is rotated in a state where the middle of a projecting support plate 4 is screwed into the bolt 1 and the supporting piece 4 is bent and small in the hole b to be closed in the wall a so as to project from the hole b to the other surface. Then, the closing plate 3 is pressed against the surface of the wall a to close the hole b.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an obturator for closing an unnecessary hole that has been previously opened, for example, in a ceiling wall or other wall surface in construction work and the like.

[0002]

[Prior art]

 When the hole provided on the wall surface is no longer needed, conventionally, a plate piece larger than the hole is hit, and it is nailed and held by an adhesive or a sticky tape, or a suitable closure is used. It is generally closed.

[0003]

[Problems to be solved by the device]

 When the plate piece in the above-mentioned conventional means is occluded and closed, the holding means of the plate piece is troublesome and the appearance after the blockage is unsightly, and after a certain period of time, the holding is loosened and inadvertently falls. Also, the conventional obturator requires operation on both sides of the wall surface when it is used, which is inconvenient for obstructing the hole on the ceiling surface in particular.

[0004]

[Means for Solving the Problems]

 The present invention eliminates the inconvenience of the above-mentioned conventional means, and provides an obturator that can be easily operated by operating only one surface of a wall when closing an unnecessary hole in the wall surface, and particularly makes the operation on the ceiling surface easy. A bolt with a large diameter at one end is loosely fitted in a bolt of an appropriate length, which is larger than the hole to be closed, so that it can move in the axial direction. In addition, a rectangular support piece made of an elastic metal material longer than the hole is screwed in, and a claw piece is projectingly provided on the back surface of the support piece.

[0005]

[Action]

 As shown in the embodiment of FIGS. 2 to 4, the hole obturator according to the present invention starts from one surface (the lower surface in the illustrated example) of the wall a having the hole b to be closed, as shown by the solid line in FIG. , Both ends of the elastic support piece 4 screwed to the bolt 1 are manually bent downward as shown by the arrow x to insert the support piece 4 into the hole b. As shown by the phantom line in FIG. When the support piece 4 returns to its original shape by elasticity by projecting it through the hole b to the other surface of the wall a and releasing it, the obturator is held on the wall surface by the support piece 4 as shown by the solid line in FIG. It Next, when urging the bolt 1 by hand from this state, the claw piece 5 on the back surface of the support piece 4 is pressed against the wall a surface, so that the support piece 4 is rotated by the engagement of the claw piece 5. Therefore, if the bolt 1 screwed into the support piece 4 is continuously rotated while being urged downward, the bolt 1 moves upward with respect to the support piece 4 as shown by a phantom line in FIG. The closing plate 3 held by the head 2 also moves upward as it is screwed, and finally the closing plate 3 comes into contact with the lower surface of the wall a to close the hole b. Elastically presses against the upper surface of the wall a, and securely holds the closing plate 3 against the lower surface of the wall a through the bolt 1 to seal the hole b.

[0006]

【Example】

 An embodiment of the hole obturator according to the present invention will be described with reference to FIG. Reference numeral 1 is a bolt having a large diameter head 2 at one end and having a proper length, and a closing plate 3 is loosely inserted into the bolt 1 so as not to come out of the head.

The closing plate 3 is not limited to the circular plate in the illustrated example, and its shape is arbitrary, and is at least a larger plate than the hole b on the surface of the wall a that needs to be closed.

Reference numeral 4 denotes a support piece made of an elastic metal material, which is formed in a rectangular shape having a width smaller than the hole b that requires closing of the surface of the wall a and larger than the diameter of the hole b. A sharp claw piece 5 having a sharp tip formed by punching as shown in the drawing was projected, and the middle portion of the support piece 4 was screwed and connected to the bolt 1.

In the illustrated example, a nut or spiral boss piece 5a is integrally bonded to the intermediate portion of the support piece 4, and the bolt 1 is screwed into the nut or boss piece 5b. In addition, the bent portions 5a are formed on both sides of the threaded portion of the support piece 4 to facilitate the downward bending.

In the hole blocker configured as described above, the outer sides of the both-side bending portions 5a of the support piece 4 are manually bent downward as described above with reference to the hole b of the wall a. After projecting from the upper surface to the other surface, it is automatically restored to its original shape by elasticity, straddling the hole b and held on the surface of the wall a, and locked with the claw piece 5 projecting to the lower surface so as not to rotate. By rotating the bolt 1, the opening / closing plate 3 is pressed to close the hole b, and the hole b is closed.

[0011]

[Effect of device]

 The hole obturator according to the present invention can obstruct the hole only by screwing the bolt with a part of the support piece inserted from one surface of the wall surface having the hole that needs to be obstructed. The plate, which is extremely simple and has a closed hole, is pressed against the wall surface by the elasticity of the support piece to ensure the tightness of the hole, and its attachment is robust without loosening.
