Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article mounting tool for mounting an article such as a handrail on the surface of a wall forming member and a position spacer for the article mounting tool.

[0002]

2. Description of the Related Art When an article such as a handrail is mounted on the surface of a wall-constituting member, if the wall-constituting member is fragile such as gypsum board, the surface side of the wall-constituting member is attached (on the side where the article is located). If the article is attached with a mounting screw, etc., it will not be possible to support a large load from the article and cannot be adopted. Therefore, an opening is formed in the wall surface forming member, the anchor piece is inserted through the opening portion and is arranged on the back surface side of the wall surface forming member, and the anchor piece in a state of being closely adhered to the back surface side of the wall surface forming member. The load from the article is supported.

Conventionally, various kinds of article attachments have been proposed as an article attachment utilizing an anchor piece to be inserted through an opening. However, the attachment member and the anchor piece provided on the front surface side of the wall forming member are There is one in which the wall portion forming member is sandwiched between the anchor piece and the mounting member by connecting the opening portion of the wall surface forming member via a mounting bolt that is inserted. Then, among those having a mounting bolt, one end portion of the mounting bolt is connected to the anchor piece in advance, and the anchor piece moves from the opening of the wall surface constituent member to the back surface side thereof while gripping the base end portion of the mounting bolt. Some of them are designed to be inserted (Japanese Patent Laid-Open Nos. 2000-145089 and 20).
01-241410, JP 2001-24141 A
No. 8, Japanese Patent Application Laid-Open No. 9-72318, and Japanese Patent No. 290.
3313 gazette). In addition, JP 2001-3249A
No. 2 gazette discloses that an anchor piece is wall-mounted by the double-sided adhesive tape before the double-sided adhesive tape is affixed to a predetermined surface of the anchor piece, which is brought into contact with the rear surface side of the wall surface component member, and fixed by a bolt. It has also been proposed to temporarily fix the back surface of the component member in advance.

[0004]

By the way, the support of the load from the article by the anchor piece is carried out mainly by the pressure contact of the anchor piece with the back surface side of the wall surface constituting member. For example, when the anchor piece is arranged so as to extend upward from the opening of the wall surface forming member, a downward load is applied to, for example, a handrail as an article arranged on the front surface side of the wall surface forming member and connected to the mounting bolt. When the force acts, the anchor piece is pressed against the back surface side of the wall surface forming member, and the load bearing is effectively performed. On the other hand, in the state in which the anchor piece extends upward from the opening as described above, when an upward load is applied to the handrail, the anchor piece extending upward from the opening is removed from the back surface side of the wall surface forming member. Because it receives the force to be peeled off,
This makes it impossible to effectively support the downward load.

In order to solve such a problem, the anchor piece is positioned so that the anchor piece extends in a direction opposite to the direction of the load acting on the article, assuming the action direction of the load acting on the article in advance. . Further, the anchor piece is set to extend in, for example, both the upper and lower directions with the opening of the wall surface forming member as a boundary, so that it is possible to cope with both the upward and downward loads acting on the article. It is also done.

In consideration of the above circumstances, the present applicant has developed the following article mounting tool from the viewpoint that the load can be supported in a wide direction. That is, the first anchor piece and the second anchor piece are used as the anchor piece inserted through the opening formed in the wall surface forming member on the back surface side thereof, and the first anchor piece is attached to one end of the mounting bolt. The second anchor piece is rotatably fitted on the base end side of the mounting bolt with respect to the first anchor piece without being screwed into the mounting bolt.

According to the above-described article mounting tool, the first anchor piece and the second anchor piece are inserted in the rear surface side through the opening of the wall surface forming member in a state of being overlapped with each other in the axial direction of the mounting bolt. By making the mounting bolt extend in the lengthwise direction of the opening of the wall surface forming member (thickness direction of the wall surface forming member), the second anchor piece is made to extend downward due to gravity, and the first anchor piece is attached. By rotating the base end portion of the bolt so as to extend upward, an anchor piece structure that extends long in the vertical direction is obtained.

In the article fixture of the above structure developed by the applicant, it is desired that the two anchor pieces are deployed at a predetermined deployment angle. For example, when the two anchor pieces are in a deployed state in which an angle of about 180 degrees is formed around the mounting bolt, the second anchor piece extends vertically downward due to its own weight, and therefore the mounting bolt is attached from the surface side of the wall surface forming member. While rotating, the first anchor piece needs to be in a posture in which the first anchor piece faces almost straight upward. In this case, since each anchor piece is located on the back surface side of the wall surface forming member, at least check the posture state of the second anchor piece by referring to the rotational position of the mark or the like provided on the base end portion of the mounting bolt. It was inevitable. That is, the posture state of the second anchor piece cannot be directly seen by an operator who is on the front surface side of the wall surface forming member, which makes it difficult to accurately set the predetermined deployed state of the two anchor pieces. Occurs. Such a problem also occurs when the two anchor pieces are deployed at an angle other than 180 degrees.

It may also be desired that the two anchor pieces be in a predetermined mounting angle state in which they are inclined by a predetermined angle with respect to the vertical line. For example, when attaching the handrail to the stairs, it is desirable that each anchor piece does not extend in the vertical direction but extends in a direction orthogonal to the inclination direction of the stairs (direction inclined with respect to the vertical direction). Be done. In this case, the second anchor piece is in a state of extending vertically downward due to its own weight until it is left as it is, so that it is difficult to arrange the second anchor piece in an inclined manner with respect to the vertical direction.

The present invention has been made in consideration of the above circumstances. A first object of the present invention is to provide an article mounting tool which can surely bring two anchor pieces into a predetermined deployed state. To provide. A second object of the present invention is to provide, in addition to the above-mentioned first object, an article mounting tool capable of surely arranging two anchor pieces at a desired mounting angle. A third object of the present invention is to provide a position spacer used to achieve the above second object.

[0011]

In order to achieve the first object, the following solution method is adopted in the present invention. That is, as described in claim 1 in the claims, the anchor piece inserted through the opening formed in the wall surface forming member and arranged on the back surface side of the wall surface forming member and the front surface side of the wall surface forming member. And the mounting member arranged in
An article mounting tool in which the wall surface forming member is sandwiched between the anchor piece and the mounting member by connecting the opening portion via a mounting bolt that is inserted, and the article mounting tool includes: An anchor piece and a second anchor piece are provided, a tip end portion of the attachment bolt is integrally connected to a base end portion of the first anchor piece, and a attachment hole is provided at a base end portion of the second anchor piece. And the second anchor piece is positioned closer to the base end side of the mounting bolt than the first anchor piece, and the mounting hole is rotatable without being screwed into the mounting bolt. Is provided with a position spacer having a main body part that is inserted into the opening part and a restricting part that projects and extends from the main body part, and the main body part is screwed with the mounting bolt. Has a through hole that is rotatably penetrated without When the first anchor piece and the second anchor piece are deployed at a predetermined deployment angle with the mounting bolt as the center, when the main body part is inserted into the opening part, the restricting part causes the anchor part to move. It is arranged so as to abut on each side surface of the base end portion. With this, by inserting the main body of the position spacer into the opening of the wall-forming member and adjusting the rotational position of the mounting bolt so that the restricting portion is in contact with the side surface of each anchor piece, In addition, a state in which each anchor piece is expanded at a predetermined angle can be obtained.

In order to achieve the second object, the following solution is adopted in the present invention. That is, as described in claim 2 in the claims,

Therefore, it can be inserted into the through hole (corresponding to claim 3). In this case, the position spacers can be manufactured easily and inexpensively, for example, by injection molding. Further, the position spacer can be fitted to the mounting bolt from the side by utilizing the notch.

The first anchor piece is screwed to the mounting bolt and is temporarily fixed so as to rotate integrally with each other, and when the torque of a predetermined value or more is received, the temporary fixing is broken and the first anchor piece is broken. The anchor piece can be relatively rotatable with respect to the mounting bolt while maintaining the screwed state (corresponding to claim 4). As a result, the work of positioning the anchor pieces on the back surface side of the wall surface component can be facilitated by making the mounting bolt long. Further, by strongly screwing the mounting bolt from the state in which the wall surface forming member is sandwiched between each anchor piece and the mounting member,
It is possible to release the temporary fixing of the mounting bolt to the first anchor piece so that the mounting bolt is deeply inserted into the back surface side of the wall surface forming member, and the mounting bolt remains protruding to the front surface side of the wall surface forming member for a long time. You can prevent the situation.

At least the second anchor piece among the first anchor piece and the second anchor piece is provided with an adhesive material on a predetermined surface which abuts on the back surface side of the wall surface forming member. It is possible (corresponding to claim 5). In this case, the bearing capacity of the anchor piece can be improved by utilizing the adhesive force of the adhesive material to the wall surface constituting member. Further, it is also preferable for temporarily fixing the anchor piece to a desired position on the back surface of the wall surface forming member during the work to facilitate the subsequent work.

In order to achieve the third object, the position spacer in the article mounting tool of the present invention adopts the following solution method. That is, as described in claim 6 in the claims, an article mounting tool having a pair of anchor pieces inserted through an opening formed in a wall surface forming member and arranged on the back surface side of the wall surface forming member. A position spacer to be used, which is insertable into the opening and has a main body having a through hole extending in the axial direction of the opening, and one axial end of the through hole from the main body. And a pair of restricting portions having a space in the circumferential direction of the through hole, projecting and extending toward the side,

[0018]

1 to 13, an article mounting tool M has a first anchor piece 1, a second anchor piece 2, a mounting bolt 3, and a mounting member 4 (FIGS. 1 to 1). In FIG. 7, not shown, see FIG. The wall pieces H are sandwiched between the anchor pieces 1 and 2 and the mounting member 4, as will be described later.

Each of the anchor pieces 1 and 2 is made of a metallic material (for example, a steel plate) having a thickness of several mm and excellent in rigidity, and a synthetic resin (including a fiber-reinforced synthetic resin-the same applies hereinafter), so that the anchor pieces 1 and 2 are elongated and curved as a whole. It is made into a shape. That is, each of the anchor pieces 1 and 2 has a shape that is curved in one direction as a whole, and the degree of bending is particularly strong on the tip end side thereof, and is largely bent in the lateral direction.
Then, when both anchor pieces 1 and 2 are rotated relative to each other around the mounting bolt 3 and overlapped with each other, the shape is set so as to be aligned so as not to protrude from each other in the width direction (almost congruent shape). Configuration).

A screw hole 1 is formed in the base end 1e of the first anchor piece 1.
a is formed, and the tip portion 3f of the mounting bolt 3 is screwed into the screw hole 1a. Then, the mounting bolt 3 and the first anchor piece 1 are temporarily fixed in a state where the first anchor piece 1 is screwed into the tip portion 3f of the mounting bolt 3. This temporary fixing is set so that the first anchor piece 1 and the mounting bolt 3 rotate integrally and are released when a relative torque of a predetermined value or more acts. In order to perform such temporary fixing, it can be obtained by, for example, caulking or partial welding.

The second anchor piece 2 is formed at the base end portion 2e (of the second anchor piece 2 on the base end portion 3e side of the mounting bolt 3 with respect to the mounting bolt 3 with respect to the first anchor piece 1. The mounting hole 2a) is rotatably fitted. That is,
The second anchor piece 2 is freely rotatable without being screwed onto the mounting bolt 3, and is rotatable relative to the first anchor piece 1 and the mounting bolt 3, respectively.

The anchor pieces 1 and 2 are arranged on the back surface side of the wall surface component H through the openings 11 formed in the wall surface component H, and are connected via the mounting bolts 3. The wall surface constituting member H is sandwiched between 1 and 2 and a mounting member 4 which will be described later, and the attachment of the anchor pieces 1 and 2 to the wall surface constituting member H is completed. The points of this mounting work will be described later.

In the present invention, the position spacer 8 is used. In the embodiment, the position spacer 8 is an integrally molded product made of synthetic resin as a whole. The position spacer 8 has a main body portion 8a and a pair of regulating portions 8b and 8c. The main body portion 8a has a substantially cylindrical shape, and the outer diameter thereof is sized so that the main body portion 8a can be fitted into the opening portion 11 formed in the wall surface forming member H without rattling. A through hole 8d is formed in the body portion 8a. Through hole 8d
The inner diameter of is set to be slightly larger than the outer diameter of the mounting bolt 3, and is rotatable relative to each other with the mounting bolt 3 inserted in the through hole 8d.

Further, a cutout portion 8e is formed in the main body portion 8a. The cutout portion 8e communicates the through hole 8d with the outer peripheral surface of the main body portion 8a. By bringing the mounting bolt 3 closer to the notch 8e from the outer side in the radial direction,
It is possible that the mounting bolt 3 passes through the cutout portion 8e and is inserted into the through hole 8d. More specifically, the opening width of the cutout portion 8e is larger than the outer diameter of the mounting bolt 3 near the outer peripheral surface of the main body portion 8a, while it is larger than the outer diameter of the mounting bolt 3 near the through hole 8d. It is formed to be slightly smaller. As a result, when the mounting bolt 3 is pushed into the notch 8e from the outside in the radial direction, the main body 8a is elastically deformed and the opening width of the notch 8e is forcibly expanded. , Mounting bolt 3 is through hole 8
It is fitted to d. As long as a large external force that expands the cutout portion 8e does not act, the fitting state of the mounting bolt 3 with the through hole 8d is maintained.

The restricting portions 8b and 8c are formed so as to project from the main body portion 8a so as to extend in the axial direction of the through hole 8d. More specifically, the restricting portions 8b and 8c
Toward the tip side of the mounting bolt 3 (each anchor piece 1,
2) so as to extend (in the direction in which 2 exists)
Is projected from. In the embodiment, the protruding lengths of the restricting portions 8b and 8c are the same as each other.

Explaining the lengths of the restricting portions 8b and 8c, consider a state in which the anchor pieces 1 and 2 are slightly separated from the back surface side of the wall surface forming member H (the double-sided adhesive tape described later is used for the wall forming member H). At an interval that does not touch the back side,
1 to 2 cm). In this state, with the mounting bolt 3 inserted into the through hole 8d of the position spacer 8, the main body portion 8a thereof is inserted into the opening portion 11. In this inserted state, the lengths of the tips of the restriction parts 8b and 8c reach at least the side surface of the first anchor piece 1, that is, the restriction parts 8b and 8c are the base end portions of the anchor pieces 1 and 2. The length is such that it can contact the side surface of the.

The restricting portions 8b and 8c are arranged at intervals in the circumferential direction of the through hole 8d, and in the embodiment, they are arranged at an interval of about 180 degrees. The facing surfaces of the restricting portions 8b and 8c are substantially flat surfaces and are set to be substantially parallel to each other. The spacing between the restriction portions 8b and 8c is set to be slightly larger than the width of the base end portions 1e and 2e of the anchor pieces 1 and 2.

The facing surfaces of the restricting portions 8b and 8c are brought into contact with the side surfaces of the base end portions of the anchor pieces 1 and 2 so as to be free from the mounting bolts 3 of the anchor pieces 1 and 2, as will be described later. It controls the rotation. Therefore, the regulating portions 8b, 8
Both side surfaces of the base end portions of the anchor pieces 1 and 2 with which the c is abutted are formed to be flat surfaces substantially parallel to each other.

As shown in FIGS. 4 and 5, with the mounting bolt 3 penetrating the through hole 8d, the position spacer 8 is moved in the direction of the anchor pieces 1 and 2 (the tip 3f direction of the mounting bolt 3).
Consider a case in which the base ends 1e and 2e of the anchor pieces 1 and 2 are clamped by the pair of restricting portions 8b and 8c by moving the base end portions 1e and 2e toward each other. In this state, the first anchor piece 1
The second anchor piece 2 and the second anchor piece 2 are in a predetermined deployed state in which they extend in opposite directions to each other by approximately 180 degrees (the relative angle between the anchor pieces 1 and 2 is approximately 180 degrees). In this predetermined deployed state,
When one of the anchor pieces 1 and 2 is rotated, the other anchor piece is also rotated by the same angle via the restricting portions 8b and 8c, and the relative angle between the anchor pieces 1 and 2 is made. Remains constant (maintaining the predetermined expanded state).

FIGS. 4 and 5 show a state in which the anchor pieces 1 and 2 extend in vertically opposite directions along the substantially vertical direction in the predetermined developed state (the first anchor piece 1 extends upward, 2 The state where the anchor piece extends downward). 6 and 7 show that the mounting bolt 3 is removed from the state of FIG. 4 and FIG.
It shows a state of being rotated about 0 degree. In FIG. 6 and FIG. 7, the vertical direction line is indicated by a symbol E.

The base end portion 3e of the mounting bolt 3 is particularly shown in FIG.
As shown in FIG. 3, an engaging hole 3d is formed in the base end surface so that a rotary tool such as a hexagonal wrench can be engaged with the engaging hole 3d. The cross-sectional shape of the engagement hole 3d may be an appropriate shape such as a quadrangle as long as it is a different shape with which the rotary tool is engaged so that the rotary tool cannot rotate relative to it.

Of the anchor pieces 1 and 2, the wall surface member H
A double-sided adhesive tape 9 or 10 is preliminarily attached to the predetermined surfaces 1g and 2g facing the back surface side of the above (see particularly FIG. 1). Each of the double-sided adhesive tapes 9 and 10 serves as a rotation resistance imparting means and a peeling-preventing means. 2g (the surface that faces the back surface side of the wall surface forming member H) is previously bonded, and the other bonding surface is covered with release paper.
Then, the release paper is peeled off immediately before construction, and the other adhesive surface is exposed.

As shown in FIG. 1, the double-sided adhesive tape 9 adhered to the predetermined surface 1g of the first anchor piece 1 has a small area so as to be located only at a substantially middle portion in the longitudinal direction. On the other hand, the double-sided adhesive tape 10 adhered to the predetermined surface 2g of the second anchor piece 2 has a large area extending from the substantially middle portion in the longitudinal direction to the vicinity of the tip.

Of the second anchor piece 2, the double-sided adhesive tape 1
A plurality of protrusions 2b are formed on the surface opposite to the predetermined surface 2g to which 0 is adhered (see FIG. 5). More specifically, four protrusions 2b are formed in total, and each anchor piece 1 is formed.
And 2 are overlapped with each other, the two protruding portions 2b are located on the side close to the mounting bolt 3 while straddling the double-sided adhesive tape 9 of the first anchor piece 1, and the remaining two protruding portions 2b are mounted on the mounting bolts. It is located on the side farther than 3. In addition, the protrusion 2b
In the embodiment, is formed at the time of press forming the second anchor piece 2 made of a metal plate.

The protruding heights of the protrusions 2b are the same and are formed to be slightly higher than the thickness of the double-sided adhesive tape 9 adhered to the first anchor piece 1. That is, when the anchor pieces 1 and 2 are overlapped with each other in the axial direction of the mounting bolt 3, a predetermined gap larger than the thickness of the double-sided adhesive tape 9 is formed between the anchor pieces 1 and 2, and the predetermined gap is formed. The double-sided adhesive tape 9 of the first anchor piece 1 is located in the gap. That is, the double-sided adhesive tape 9 of the first anchor piece 1 is located in the space surrounded by the protrusions 2b (which can also be regarded as a recess).

Each protrusion 2b is a double-sided adhesive tape 9 of each protrusion 2b and the first anchor piece 1 when the first anchor piece 1 and the second anchor piece 2 are relatively rotated about the mounting bolt 3. Positioned so that and do not interfere with each other.
In other words, the movement locus (rotation locus) of the protrusion 2b around the mounting bolt 3 is set so as to be displaced from the movement locus (rotation locus) of the double-sided adhesive tape 9.

Next, with reference to FIGS. 8 to 10, a method of attaching the article attachment M to the wall constituting member H will be described. As a preparation before the attachment, the double-sided adhesive tape 9,
The release paper 10 is peeled off.

After the above-mentioned preparation is completed, first, the two anchor pieces 1 and 2 are made to overlap each other, and the anchor pieces 1 and 2 are inserted into the opening 11 from the tip end side thereof. When both anchor pieces 1 and 2 are overlapped,
The protrusion 2 b prevents the double-sided adhesive tape 9 of the first anchor piece 1 from coming into contact with the second anchor piece 2. From this state, the two anchor pieces 1 and 2 are twisted in and further inserted deeply into the opening 11. At the time of this insertion, by setting the curved shape of the anchor pieces 1 and 2, compared with the case where the anchor pieces are straight, the insertion can be performed even if there is only a small space on the back surface side of the wall surface component H. In this way, the insertion of the two anchor pieces 1 and 2 into the opening 11 progresses, and eventually the anchor pieces 1 and 2 completely pass through the opening 11.

When the anchor pieces 1 and 2 have completely passed through the opening 11, the second anchor piece 2 is in a posture of facing vertically downward due to its own weight. From this state, the base end portion 3e of the mounting bolt 3 is rotated to move the first anchor piece 1
Is in a posture in which it extends upward (a predetermined deployed state in which the first anchor piece 1 and the second anchor piece 2 form an angle of about 180 degrees), and this state is shown in FIG.

In the state of FIG. 8 in which the first anchor piece and the second anchor piece 2 extend in the substantially vertical direction, the position spacer 8
Is fitted into the through hole 8d by utilizing the cutout portion 8e (a state before completion of fitting is shown in FIGS. 1 and 8). After fitting the mounting bolt 3 into the through hole 8d, the position spacer 8 is moved along the mounting bolt 3 to insert the main body portion 8a into the opening 11 (see FIG. 9).
When the position spacer 8 is fitted in the opening 11, the center of the opening 11 and the axis of the mounting bolt 3 are substantially aligned with each other.

From the state shown in FIG. 9, a pair of restricting portions 8b and 8c are provided.
The rotation position of the mounting bolt 3 is adjusted from the base end side so that the base ends 1e and 2e of the anchor pieces 1 and 2 can be sandwiched by. The pair of restricting portions 8b is in contact with one side surface of the base end portions 1e and 2e of the anchor pieces 1 and 2, and the other restricting portion 8c is the base end portions 1e and 2e of the anchor pieces 1 and 2.
While being in contact with the other side surface of each of the anchor pieces 1 and 2,
A predetermined deployed state is secured (Fig. 10). In addition, the base end portion 1 of each anchor piece 1, 2 is formed by the pair of restriction portions 8b, 8c.
Even if the position spacer 8 is inserted deeply so as to sandwich e and 2e, if the relative angle between the anchor pieces 1 and 2 does not correspond to the desired deployed state, the restriction portion 8b or 8c.
At least one of the end faces of which is either anchor piece 1, 2
It cannot be inserted deeply by abutting on the plate surface of. In other words, the fact that the position spacer 8 is inserted deeper than a predetermined amount also confirms that the base end portions 1e and 2e of the anchor pieces 1 and 2 are held by the pair of restricting portions 8b and 8c.

When the anchor pieces 1 and 2 have a desired mounting angle such that they extend substantially vertically as shown in FIGS. 4 and 5, for example, the developed state and mounting of the anchor pieces 1 and 2 are performed. Since both angles are as desired (Fig. 1
0 state), the double-sided adhesive tapes 9 and 10 are adhered to the back surface of the wall surface component H by pulling the base end portion 3e of the mounting bolt 3 toward you. As a result, each anchor piece 1, 2
Is temporarily fixed to the wall surface constituting member H in a desired developed state and at a desired mounting angle (FIG. 12). After temporary fixing using double-sided adhesive tapes 9 and 10,
Even if the mounting bolt 3 is released from the hand, it is possible to prevent the anchor pieces 1 and 2 from accidentally falling on the back surface side of the wall surface component H.

As shown in FIG. 7, when the mounting angle state in which the anchor pieces 1 and 2 are inclined with respect to the vertical direction E is the desired mounting angle state, the rotational position of the mounting bolt 3 is changed from the state of FIG. Is adjusted so that the first anchor piece 1 is at a position inclined with respect to the vertical direction E as shown in FIG. 7. At this time, as described above, according to the rotation of the mounting bolt 3, that is, the rotation of the first anchor piece 1, the restriction portions 8b, 8
The second anchor piece 2 is also rotated by the same angle as the first anchor piece 1 via c. In other words, the desired deployed state of the first anchor piece 1 and the second anchor piece 2 (in the embodiment, the deployed state in which the anchor pieces 1 and 2 form a relative angle of approximately 180 degrees) is the regulating portion of the position spacer 8. While being maintained by 8b and 8c, the first anchor piece 1 and the second anchor piece 2 rotate together with the mounting bolt 3. 6,
After the desired mounting angle as shown in FIG. 7 is reached, the mounting bolt 3 is pulled toward the front and temporarily fixed using the double-sided adhesive tapes 9 and 10.

Here, when the thickness of the wall surface constituting member H is larger than the thickness of the main body portion 8a, as shown in FIG.
It is preferable to separately use the spacer 7 for adjusting the thickness.
The spacer 7 is made of, for example, a synthetic resin,
It corresponds to the difference in the thickness of the wall surface constituting member H, that is, the difference in the length of the opening 11, and is attached to the mounting bolt 3 on the side of the base end 3e of the mounting bolt 3 with respect to the position spacer 8. That is, the spacer 7 has a thickness corresponding to the thickness of the wall surface constituting member H, and the outer diameter thereof is made substantially the same as the inner diameter of the opening portion 11 and fitted into the opening portion 11. The spacer 7 has an insertion hole 7a at the center thereof through which the mounting bolt 3 is inserted, but a notch 7b is formed in the circumferential direction so that the spacer 7 can be easily attached to and removed from the mounting bolt 3. The notch 7b is used to remove the mounting bolt 3 and mount it.

The opening width of the notch 7b is determined by the mounting bolt 3
The diameter of the notch 7b is made slightly smaller than the diameter of the notch 7b, and when attaching or detaching, the opening width of the notch 7b is expanded by utilizing elastic deformation. Further, by adding spacers having the same shape and different thicknesses, it may be adapted to the case where the wall surface constituting members H have different thicknesses.

After temporary fixing using the double-sided adhesive tapes 9 and 10, as shown in FIG. 13, a flange-shaped connection of the larger diameter of the opening 11 to the base end 3e of the mounting bolt 3 is performed. After fitting the member 21 and the washer 22, the lock nut 23 screwed into the mounting bolt 3 is tightened to press the connecting member 21 against the surface of the wall surface constituting member H. The connecting member 21 and the lock nut 23 substantially form the mounting member 4. The wall surface constituting member H is firmly sandwiched between the anchor pieces 1 and 2 and the mounting member 4. A male screw portion 21a is formed on the outer peripheral surface of the connecting member 21 for attaching an article to be described later.

Next, a rotary tool is applied to the engaging hole 3d formed in the base end portion 3e of the mounting bolt 3 to attach the mounting bolt 3
Is applied to the first anchor piece 1 with respect to. As a result, the temporary fixing between the first anchor piece 1 and the mounting bolt 3 is released, and by further applying a rotational force to the mounting bolt 3, the mounting bolt 3 deeply advances to the back surface side of the wall surface component H, and the wall surface The projecting length of the constituent member H toward the front surface side is reduced (transition from the state of FIG. 12 to the state of FIG. 13).

In the state where the attachment is completed, the anchor pieces 1 and 2 need not only have a load in the direction in which they are pressed against the back surface side of the wall surface constituting member H, but also have a load in the peeling direction, and further the wall surface constituting member. The load in the direction of sliding (rotating direction) along the back surface of H can also be supported, and the load bearing ability in a wide direction becomes large. By the way, when the load from an article (not shown) is downward in the mounting completed state of FIG. 13, the force in the direction in which the first anchor piece 1 extending upward is pressed against the back surface side of the wall surface constituting member H is applied. The second anchor piece 2 that receives the load is sufficiently supported, and in addition to this, the second anchor piece 2 extending downward receives a force in the direction of being separated from the back surface side of the wall surface component H, but the second anchor piece 2 is Since the peeling is restricted by the adhesive action of the double-sided adhesive tape 9, the load bearing capacity becomes larger than before by this amount (therefore, the double-sided adhesive tape 10 has a large area and at least the second anchor piece 2). It is set to be located at the tip).

Next, an example of fixing the handrail 35 as an article will be described with reference to FIG. Handrail 3
5 has a flange portion 35a at its end portion, and a fixing tool 36 is rotatably fitted to the end portion of the handrail 35 in a state where the flange portion 35a is prevented from coming off. Fixture 36
Is formed in a cap shape and has an internal thread portion 36 on its inner surface.
a is formed, and the female screw portion 36 a is screwed into the male screw portion 21 a formed on the outer periphery of the connecting member 21.
At least the end portion of the handrail 35 on the side of the flange portion 35a is formed into a tubular shape, and when the fixing tool 36 is deeply screwed into the connecting member 21, the lock nut 23 is attached to the handrail 35.
It is inserted inside.

Although the embodiments have been described above, the articles are not limited to handrails, and various articles such as lighting appliances and the like that are required to be attached to the wall surface constituting member H. You can Further, it is possible not to temporarily fix the first anchor piece 1 and the mounting bolt 3 (always rotate integrally). As the shapes of the first anchor piece 1 and the second anchor piece 2, an appropriate shape that allows the opening 11 to be inserted can be selected. As the adhesive material, other than the surface adhesive tapes 9 and 10,
It is also possible to use an adhesive, especially a quick-drying two-component curing type adhesive. Further, the adhesive may be used only for the second anchor piece 2, or the adhesive may not be used at all.

The method of fixing an article using the mounting bolts 3 is not limited to the case of using the connecting member 21 as shown in the embodiment, and for example, an article such as a bracket or a hanger can be directly used with its back surface as a holding portion. An appropriate method such as fixing to the mounting bolt 3 can be selected. Mounting member 4
As various types, various types can be adopted, for example, a type in which the connecting member 21 is screwed into the mounting bolt 3 is not a type in which the connecting member 21 is divided into a plurality of members, and only one member is used. You can also

The position spacer 8 is not limited to the synthetic resin,
It can be formed of an appropriate material such as metal. Further, the restricting portions 8b and 8c correspond to the desired relative angle (desired deployed state) of the two anchor pieces 1 and 2, not limited to the case where the contact surface with the anchor pieces 1 and 2 is one surface. And make a predetermined angle 2
It can also consist of two continuous faces. For example, when both anchor pieces 1 and 2 make a relative angle of, for example, 90 degrees in a desired deployed state, a pair of restricting portions 8b,
One of the control portions of 8c has two contact surfaces that make an angle of 90 degrees, and is in contact with one side surface of the base end portion of each of the anchor pieces 1 and 2, and the other control portion has a contact angle of 270 degrees. It suffices to have two contact surfaces that form an angle so that they can contact the other side surface of the base end portion of each anchor piece 1, 2. Only one of the restriction parts 8b and 8c may be provided.
