Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary holder for a corner finishing material used when fixing a corner finishing material such as a skirting board or a ceiling parting edge to a corner where two mutually orthogonal surfaces intersect in a building.

In general, a corner finishing material such as a skirting board or a ceiling edge is attached to a corner where two surfaces, a vertical plane and a horizontal plane, intersect inside a building. These corner finishes are often coated with adhesive to adhere to vertical surfaces such as walls or horizontal surfaces such as floors. Conventionally, the corner finishing material is temporarily fixed by pressing it against the vertical or horizontal surface with a piece of wood or the like in order to prevent the corner finishing material from floating up from the horizontal surface and creating a gap. However, in this conventional construction, there were variations in the degree of adhesion of the corner finishing material depending on the shape of the piece of wood and how it was installed, and it was sometimes impossible to prevent the lifting of the corner finishing material. Therefore, a number of jigs have been proposed for temporarily holding the corner finishing material by pressing it against the vertical and horizontal surfaces until the adhesive is cured (for example, Patent Documents 1 to 3).

Each of the jigs described in Patent Documents 1 to 3 can be engaged with the corner of the corner finishing material to press the corner finishing material against the horizontal and vertical surfaces, and the corner finishing material can be pushed from the horizontal surface. It is disclosed to prevent not only lifting but also lifting of the corner finish from vertical surfaces.

However, each jig described in Patent Documents 1 to 3 has a structure in which the load from the vertical direction and the load from the horizontal direction are applied to the corner finishing material at the same time, so only the load from one direction If you want to apply a corner finish, the load cannot be adjusted and must be applied from both directions. Therefore, if a corner finishing material made of a soft material such as a commonly used vinyl skirting board continues to be pressed against the horizontal surface, which is the floor surface, the upper end of the corner finishing material may be distorted and the appearance may be damaged. There is Also, if a load is applied from both directions to a corner finish that is not strong enough, the corner finish may be dented or damaged.

BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment of a temporary holder for a corner finishing material according to the present invention will be described below with reference to the drawings. Temporary holders for corner finishing materials are mainly used to press baseboards against wall and floor surfaces until the baseboards are glued to the corners where wall surfaces and floor surfaces that are orthogonal to each other inside the building intersect. Used for temporary holding. In addition to baseboards, corner finishing materials such as ceiling partition edges installed at the corners of wall surfaces and ceiling surfaces and wall partition edges installed at corners where mutually perpendicular wall surfaces intersect can be temporarily held. However, here, the corner finishing material is used as a baseboard, and the temporary corner finishing material is used until the baseboard is glued and fixed to the corners of the wall surface and floor surface that are perpendicular to each other. A case of temporary holding by a holder will be described.

As shown in FIGS. 1 and 12, the temporary holder 1 of the corner finishing material is a main body part 11 temporarily fixed to the wall surface 2, and supported by the main body part 11. One surface of the corner finishing material 4 is supported on the wall surface 2. and a second surface pressing portion 13 that is engaged with the body portion 11 and presses the other surface of the corner finishing member 4 against the floor surface 3. and a lid portion 14 fixed to the main body portion 11 with the two-sided pressing portion 13 interposed therebetween. As shown in FIG. 12, the temporary holder 1 of the corner finishing material is fixed to the wall surface 2 by a fixture N such as a nail that communicates the body portion 11, the second surface pressing portion 13, and the lid portion 14. be.

As shown in FIGS. 2, 4, and 11, the body portion 11 includes a plate portion 110 formed with a first through hole 11a penetrating in the plate thickness direction at substantially the center in the width direction, and a floor of the plate portion 110. A side plate portion 111 projecting from the edge excluding the surface 3 side toward the wall surface 2 side, and a plurality of leg portions 112 projecting from the plate portion 110 in the same direction as the side plate portion 111 and engaged with the lid portion 14. there is Further, the plate portion 110 is formed with a first fastener hole 11b for inserting the fastener N through the plate portion 110 in the thickness direction and spaced apart from the first through hole 11a.

As shown in FIGS. 5 and 12, the first surface pressing portion 12 has a first movable portion 120 that protrudes toward the floor surface 3 side from the main body portion 11 and moves in a direction perpendicular to the wall surface 2 . , and a support portion 121 that is fixed to the plate portion 110 of the main body portion 11 to support the other end portion of the first movable portion 120 and that includes a bolt 12a and a nut 12b. The first movable portion 120 includes a rod portion 12c having one end bent on the side opposite to the support portion 121, and a pressing plate fixed to the tip of the rod portion 12c and substantially parallel to the wall surface 2. A second through hole 12e is formed in the other end of the rod portion 12c so as to pass through in the radial direction and into which the bolt 12a of the support portion 121 is inserted. A bolt 12a of the support portion 121 has a female thread formed on the outer peripheral surface thereof, and a nut 12b is screwed onto the bolt 12a. Since a female thread is not formed on the inner peripheral surface of the second through hole 12e, the rod portion 12c can normally be freely moved between the plate portion 110 and the nut 12b within the length of the bolt 12a. However, as shown in FIG. 12, when the pressing plate 12d is brought into contact with the corner finishing member 4 and the nut 12b is rotated in the direction toward the plate portion 110, the movement is controlled by the tightening of the nut 12b. One end of the rod portion 12c is pushed toward the corner finishing member 4 so that the corner finishing member 4 can be pressed against the wall surface 2 by the pressing plate 12d.

As shown in FIG. 12, the pressing plate 12d is a portion that contacts the corner finishing member 4 when the rod portion 12c is fixed by tightening the nut 12b. 12f may be pasted with a sponge-like surface material having cushioning properties. By attaching such a face material to the contact surface 12f, the corner finishing material 4 can be pressed against the wall surface 2 without damaging the surface of the corner finishing material 4. As shown in FIG.

The first movable portion 120 can be easily pulled out from the bolt 12a by rotating the nut 12b of the support portion 121 away from the plate portion 110 and removing it from the bolt 12a. If it is not necessary to press against the wall surface 2, the first movable part 120 may be removed from the support part 121 for use. The method of fixing the bolt 12a to the plate portion 110 is not particularly limited, and the bolt 12a may be fixed by welding, adhesive, or other methods. In the illustrated example, the fixing position of the bolt 12a to the plate portion 110 is a position close to the corner finishing member 4, but it may be installed at another position.

As shown in FIGS. 1 and 3, the second surface pressing portion 13 is inserted into the first through hole 11a in alignment with the plate portion 110 in the in-plane direction. and a substantially plate-shaped second movable portion 131 that engages with one plate surface of the rotating portion 130 and moves parallel to the plate portion 110 when the rotating portion 130 is rotated. is doing. As shown in FIGS. 2 and 6, the rotary portion 130 has spiral projections 13a formed on the plate surface on the side of the second movable portion 131 at intervals and gradually decreasing in diameter toward the center of the vortex. Further, a knob 13b is formed so as to protrude from the plate surface on the opposite side of the projection 13a and rotate the rotating portion 130. As shown in FIG. A flange 13 c that protrudes laterally from the side surface of the rotating portion 130 and engages with the plate surface of the plate portion 110 on the second movable portion 131 side is formed.

As shown in FIGS. 2 and 7, the second movable portion 131 is an elongated body having a plurality of engagement pieces 13e formed along the longitudinal direction on the surface on the rotating portion 130 side to engage between the vortices of the protrusions 13a. It has a plate-like engaging portion 13d and a plate piece 13f protruding toward the plate portion 110 from one longitudinal end of the engaging portion 13d.

The engaging piece 13e of the engaging portion 13d is formed in a gentle circular arc shape so as to engage between the vortices of the protrusion 13a. can be done. For example, when the rotating portion 130 shown in FIG. 6 is rotated clockwise when viewed from the projection 13a side, the diameter of the engaging piece 13e meshed between the vortices of the projection 13a shown in FIG. 3 gradually increases. , and is gradually pushed in the direction X shown in FIG. Conversely, when the rotating portion 130 is rotated counterclockwise, the engaging piece 13e engaged between the spirals of the protrusion 13a shown in FIG. 2 moves along the inner peripheral edge of the protrusion 13a whose diameter gradually decreases. Then, the second movable portion 131 as a whole moves in the direction Y as it is gradually pushed in the direction Y shown in FIG. Therefore, by changing the rotation direction of the rotating portion 130, the second movable portion 131 can be moved in a desired direction.

As shown in FIGS. 2 and 7, the engaging portion 13d penetrates in the plate thickness direction and has an elongated second fixture hole 13g for inserting the fixture N, spaced apart from the engaging piece 13e. The second fastener hole 13g is formed at a position that matches the first fastener hole 11b of the main body 11 when the main body 11 is overlaid. In addition, the second fixing tool hole 13g is elongated in the longitudinal direction in order to prevent interference with the fixing tool N when the engaging part 13d moves in the longitudinal direction.

As shown in FIGS. 3 and 12, the plate piece 13f is a portion that abuts against the corner finishing member 4 when the second movable portion 131 is moved in the direction Y, and has a surface opposite to the engaging portion 13d. In addition, the surface 13h, which is the surface in direct contact with the corner finishing material 4, may be pasted with a sponge-like surface material having cushioning properties. By attaching such a face material to the surface 13h, the corner finishing material 4 can be pressed against the floor surface 3 without damaging the surface of the corner finishing material 4. FIG. 7 and the like, the surface 13h of the plate piece 13f is substantially orthogonal to the engaging portion 13d, but as shown in FIG. 8, the angle θ of the surface 13h with respect to the engaging portion 13d may be an obtuse angle. With such an angle, the surface 13h abuts the corner of the corner finishing member 4 at an angle, so that a vertical load and a horizontal load can be applied to the corner finishing member 4 at the same time. Therefore, the corner finishing material 4 can be pressed efficiently.

Further, as shown in FIG. 9, the second movable portion 131 further includes a spring steel 13i that protrudes from the tip of the plate piece 13f in the direction opposite to the engaging portion 13d and bends toward the base end side of the plate piece 13f. good too. By installing such a spring steel 13i, a vertical load and a horizontal load can be simultaneously applied to the corner finishing member 4 by the plate piece 13f and the spring steel 13i. can be pressed.

As shown in FIGS. 2 and 10, the lid portion 14 is a plate-like member for preventing the second movable portion 131 accommodated inside the main body portion 11 from falling. A third through hole 14 a for inserting the leg portion 112 of the portion 11 is formed at a position corresponding to the leg portion 112 . The fixing between the third through hole 14a and the leg portion 112 may be by adhesive fixing, or the tip of the leg portion 112 is protruded from the third through hole 14a, and the leg portion 112 and the third A cap (not shown) having a diameter one size larger than the diameter of the through hole 14a may be fitted. In the latter case, when a problem occurs in the rotating part 130 or the second movable part 131, the lid part 14 can be easily removed and each member inside can be checked, so maintenance can be improved. A third fixing tool hole 14b for inserting a fixing tool N is formed in substantially the center of the width direction of the lid part 14, penetrating in the plate thickness direction. It is formed at a position where it matches the first fixing tool hole 11b and the second fixing tool hole 13g when it is superimposed on the second movable part 131 .

Next, a method of using the temporary holder 1 for the corner finishing material formed in this manner will be described. As shown in FIG. 11, the corner finishing material 4 is a member installed at a corner formed by the intersection of the wall surface 2 and the floor surface 3. It is fixed to the wall surface 2 with an adhesive, and the adhesive hardens. It is temporarily fixed by the temporary holder 1 of the corner finishing material until it is done.

As shown in FIG. Place it in the position where Then, the fixing tool N is made to communicate with the first fixing tool hole 11b of the main body part 11, the second fixing tool hole 13g of the second movable part 131, and the third fixing tool hole 14b of the lid part 14, thereby fixing the wall surface 2. The temporary holder 1 of the corner finishing material is fixed to the wall surface 2 by piercing the base material 22 such as a stud material that supports the wall board 21 to be formed.

Then, as shown in FIG. 12, the knob 13b is operated to rotate the rotating portion 130 so that the second movable portion 131 moves toward the corner finishing material 4, and the plate piece 13f moves toward the corner finishing material. The corner finishing member 4 is pressed against the floor surface 3 by contacting the upper end of the corner finishing member 4 . Further, the first movable portion 120 of the first surface pressing portion 12 is moved horizontally to bring the pressing plate 12d into contact with the corner finishing member 4, and the nut 12b of the support portion 121 is rotated in a direction approaching the plate portion 110. The nut 12b is then tightened, and the corner finishing member 4 is pressed against the wall surface 2 by the presser plate 12d.

Further, after the adhesive applied to the corner finishing material 4 is sufficiently hardened, the temporary holder 1 of the corner finishing material can be removed in the reverse order of the procedure described above. That is, the nut 12b is rotated away from the plate portion 110 to separate the pressing plate 12d from the corner finishing member 4, and the knob 13b is operated to rotate the rotating portion 130 in the opposite direction to remove the plate piece 13f from the corner. It should be separated from the part finishing material 4.
