As shown in FIGS. 1 and 2, the fixture C of the article of the embodiment 1 pivotally supports a pair of insert pieces 2 and 3 on a pivot 1 so as to be rotatable near one ends 2a and 3a thereof. The respective insertion pieces 2 and 3 are formed from the above-mentioned one end portions 2a and 3a toward the center, symmetrically in the shape of a dogleg, and the other end portions 2c and 3c are fixed portions (hereinafter collectively referred to as "fixed portions"). And a pin P formed so as to be an insertion portion into a board, and a hole 6 for forming the hole 6 for inserting the insertion pieces 2 and 3 separately from the pin P. It consists of washers 5. In other words,
Fixture C = pin P + washer 5. A cap 4 for supporting the pivot 1 is attached to the pin P, and a knob portion is formed on the cap 4.

Next, the details of each component will be described. As shown in FIG. 2A, the pin P is composed of one pivot 1 and two insertion pieces 2 and 3, and the pivot 1 is made of metal such as stainless steel and has a circular cross section. It consists of columns of fixed length.

As shown in FIG. 2 (A), the two insertion pieces 2 and 3 are symmetrical to each other, and are bent in a "dogleg shape" at a position at a constant distance from the one ends 2a and 3a. The end portions 2a and 3a are made of a long taper shape (the widths of the other end portions 2c and 3c are slightly smaller toward the tip). Holes 2d, 3d
Are formed respectively. The insert pieces 2 and 3 are made of metal such as stainless steel and are formed by punching a plate material with a press.

The other ends 2c and 3c of the insertion pieces 2 and 3 shown in FIG. 2A are formed to have substantially the same width as the other portions in the thickness direction. As shown in B), if both surface portions are formed in a tapered shape, the force required for insertion can be further reduced. The insertion pieces 2 and 3 are curved in order to make the tips sharp on one side or both sides of the longitudinal cut end surface. As the curved shape, as shown in FIGS. 3A to 3D, various shapes can be adopted. That is, as shown in FIG. 3 (E), if the angles of the insertion piece 2 or the other end portions 2c, 3c of the insertion piece 3 are made up of θ1 and θ2, The opposite inner edges have a substantially straight line shape, and the outer edges have a curve (insert piece 2 has θ2 ≈ 0, insert piece 3
Is θ1≈0), and in FIG. 3 (B), the opposite inner edges are close to linear shapes (the radius of curvature is large), that is, the insertion piece 2 has θ1> θ2, and the insertion piece 3 has In the case of θ1 <θ2, the outer edge has a larger curve, and in FIG. 3C, the opposite inner edge has a smaller radius of curvature than the outer edge, that is, Insert 1 is θ1 <θ
2, the insertion piece 3, θ1> θ2. In FIG. 3D,
Each outer edge has a substantially linear shape, and the inner edge has a curve, that is, the insertion piece 2 has θ1≈0, the insertion piece 3
Is θ2≈0.

In the various modifications shown in FIGS. 3 (A) to 3 (D), when the insertion pieces 2 and 3 are inserted into the board 10, the tips of the insertion pieces 2 and 3 smoothly move. For this purpose, as shown in FIG. 4, the curves are formed to have the same bending radius and different lengths so that the insertion pieces 2 and 3 can be inserted in the width direction. A configuration may be adopted in which the tip end portion is eccentric to the open side from the center line t2. Furthermore,
As a modified example of the other end portions 2c and 3c of the insertion pieces 2 and 3, instead of the curved portion, the edge portion may be formed into a linear bent shape as shown in FIG.

No matter how the other ends 2c, 3c (insertion portions) of the insertion pieces 2, 3 are formed, the insertion pieces 2, 3 are completely inserted, that is, as shown in FIG. As shown in FIG. 8 or FIG. 12 to FIG. 14, it is possible to form so that both tip portions are opened as much as possible in a state where the outer edge upper portions of the insertion pieces 2 and 3 are in contact with the edge portion of the hole 6 of the washer 5. desirable. In addition, as shown in FIG. 6, as an example of the insertion pieces 2 and 3,

That is, as shown in FIG. 24, a hole 11d is formed at the upper end of the hook 11c, and the hole 11d is formed.
Is also used as the washer 5, and therefore the washer 5
Is unnecessary. The lower part of the hook 11c is formed to be curved. FIG. 25 shows another example of the example in which the washer 5 is unnecessary. A horizontally elongated rectangular hole 11d is formed at the upper end of the vertically long hooking tool 11c.
The fixture C for the article may be inserted into 1d with the finger F. In addition,
The withdrawal is the same as in the first and second embodiments.

FIG. 26 shows another example in which the washer 5 is unnecessary, and is an example in the case where the article C is thick, and when the insertion pieces 2 and 3 cannot be sufficiently expanded, the article C is shown. It is enough to expand the insertion hole of No. 2 to the end. The fixture C of Examples 2 and 3 has the above-mentioned configuration, but the specific scale (length, thickness, angle, etc.) is basically the same as that of Example 1.

Although Examples 1 to 3 of the present invention have been described, a concrete example of use of the fixture C of Example 1 will be described. FIG. 27A shows a vertical direction such as a wall of a house. When the top plate 11e such as a ceiling plate is mounted on the board 10 at right angles, the L-shaped washers 5c that support the top plate 11e are attached by the fixtures C, C. In this case, by inserting the inserting pieces 2 and 3 so as to intersect and open in the horizontal direction, the load of the top plate 11e can be supported by the entire width of the inserting pieces 2 and 3, and a large supporting force can be obtained. Will be realized. This point will be described later with reference to FIG.
The same applies to the use example of. In this usage example, L
The mold washer 5c is securely fixed by the fixtures C, C, and the top plate 11
e can be held.

FIG. 27B shows a case where a mounting frame (article) 11f of a lighting fixture such as a fluorescent lamp is mounted on the lower surface of a horizontal board 10 such as a ceiling plate.
A large supporting force can be obtained only by inserting the fixtures C, C into the holes provided in the 1f itself, and the mounting frame (article) 11 can be attached to the board 10.
f can be securely attached. FIG. 27C shows
For example, when mounting the mounting frame 11g of the indoor unit of the air conditioner on the vertical board 10 such as the wall of a house, in this case, the locking washer 5d is used. Lock washer 5
The upper and lower edges of d are formed with locking edges, and holes for inserting the insertion pieces 2 and 3 are formed. Then, the mounting frame 11g is locked to the locking portion.

In each of the above-mentioned embodiments, the hole 6 of the washer 5 is formed in a plan view circular shape as shown in FIG. 28A and a rectangular shape as shown in FIG. 28C. Other than the triangular shape as shown in FIG. 28 (B), a tetragonal shape (FIG. 28 (D)), a polygonal shape (FIG. 28 ((E) to (H)), and others depending on the implementation situation. , Rectangular shapes (FIGS. 28 (I) to (K)) are used, and the shapes shown in FIG. Good.

Furthermore, in a situation where the board 10 and / or the article 11 to be fixed are repeatedly subjected to vibration, if the washer 5 or the periphery of the hole of the article 11 is made of an elastic body, the vibration is absorbed and the pin P is gradually pulled out. It has the effect of preventing On the contrary, it is desirable that the pivot 1 has a structure and a material that do not generate elasticity.

Further, in the description of each of the above embodiments and the description of the drawings, the other end portions 2c and 3c of the insertion pieces 2 and 3 are shown to have penetrated the board, but it is not always necessary to penetrate the board 10. There is no. Rather, the stress resistance is slightly reduced (by about 40%) by setting the lengths of the insertion pieces 2 and 3 in a state of being stopped within the board (for example, in the case of lightweight cellular concrete) 10.
Since the insertion force is small, usability is improved.

(Test Example 1) With respect to the fixture C of Example 2, a pull-out test of the article 11 was carried out. FIG. 29 shows the situation of the pull-out test 1, in which the necessary pull-out force in the direction opposite to the inserting direction of the fixture C was measured. As a result, when a load in the arrow direction was applied to the article 11 attached to the 9 mm-thick gypsum board (board) 10, the maximum proof strength was 10.3.
The kg weight was recorded. Normal thumbtack is about 1kg in the same test
It was heavy.

(Test Example 2) FIG. 30 shows the situation of the pull-out test 2. When a load is applied in the length direction (arrow direction) of the pivot of the fixture C, the fixture C is found to be deformed. However, the maximum resistance was 23 kg. In the claims, the reference numerals are attached to clarify the correspondence with the embodiments, but the present invention is not limited thereto.
