[0002]

2. Description of the Related Art Conventionally, an artificial wall used for free climbing is known. The artificial wall has a wall body and an artificial hold attached to the wall body. The wall body is composed of two types, a fixed wall made of concrete or the like and a climbing module made of a plate body or the like and capable of moving. The surface of the wall is formed by a flat surface or an uneven surface resembling a rock surface. Hexagon socket head cap bolt
Multiple artificial holds are attached. Climbers can climb on the artificial wall with their hands and feet on the artificial hold.

The artificial hold has a finger hook portion formed on the front surface side and an attachment portion on the back surface side. The finger rest has irregularities so that the climber can put his / her hand on it. The mounting portion has a hexagonal shape and is inserted into a receiving portion provided on the wall body. The receiving portion is formed by recessing the surface of the wall body into a hexagonal shape similar to the mounting portion. This artificial hold is mounted by inserting the mounting portion into the receiving portion in accordance with the corner of the mounting portion, and then fixing it to the wall body through the hexagon socket cap bolt. The hexagon socket head cap bolt is screwed onto a nut attached to the back surface of the wall body.

The plurality of grooves 18 of the board mounting portion 15 engage with the plurality of ridges 17 of the artificial hold mounting portion 14.

Two screw holes 22 are located outside the bolt hole 16 in a substantially diametrical direction of the bolt hole 16, and two screw holes 22 are opened. As shown in FIG. 3, the board 12 is formed of a plate body such as plywood, and the surface thereof is an uneven surface 1 resembling a rock surface.
It is covered by 2a. The board 12 has a plurality of circular openings 23 corresponding to the positions where the artificial hold 11 is to be mounted. The circular opening 23 has a circular shape slightly larger than the board mounting portion 15.

As shown in FIG. 6, the circular opening 23 is closed by a closing plate 25 screwed from the back side of the board 12 via four screws 24. On the closing plate 25,
A through hole 26 is formed at the center of the circular opening 23. The through hole 26 has the same inner diameter as the bolt hole 16. The through hole 2 is provided on the back surface 25a side of the closing plate 25.

They have almost the same inner diameter (see FIG. 6).

Using this artificial holding device 10,
By mounting the artificial hold 11 on the board 12,
As shown in FIG. 7, a climbing module 29 which is a wall surface that can be moved arbitrarily is formed. By combining the climbing modules 29, an artificial wall 30 used for free climbing is formed. Next, the operation of the artificial holding device 10 will be described.

First, the board mounting portion 15 is mounted in the circular opening 23 of the board 12. Board 1 via closing plate 25
The board mounting portion 15 mounted on the second mounting board 2 has a circular opening 23.
Inside, the ridge 17 and the groove 18 formed on the surface 15a are exposed (see FIG. 3). In addition, the artificial hold attachment portion 14 is attached to the artificial hold 11. The artificial hold attachment portion 14 attached to the artificial hold 11 exposes the protrusion 17 and the groove 18 formed on the surface 14 a on the opposite side of the finger hold portion 19 of the artificial hold 11.

Next, the artificial hold 11 is attached to the circular opening 23 at a desired position on the board 12. When mounted, the surface 14a of the artificial hold mounting portion 14 and the surface 15a of the board mounting portion 15 face each other. At this time, the orientation of the artificial hold 11 is changed to a desired orientation. The orientation of the artificial hold 11 is such that the protrusion 17 of the artificial hold mounting portion 14 and the groove 18 of the board mounting portion 15 and the groove 18 of the artificial hold mounting portion 14 and the protrusion 17 of the board mounting portion 15 engage with each other. Is determined by

That is, the ridge 17 of the artificial hold mounting portion 14 is inserted into the groove 18 of the board mounting portion 15, and the ridge 17 of the board mounting portion 15 is inserted into the groove 18 of the artificial hold mounting portion 14 (see FIG. 6). The number of steps in which the orientation can be changed can be arbitrarily changed depending on the number of the protrusions 17 and the grooves 18 of the artificial hold mounting portion 14 and the board mounting portion 15, respectively.

Subsequently, the artificial hold 11 whose direction has been determined is fixed to the board 12 with the hexagon socket head cap bolt 13. The hexagon socket cap bolt 13 is inserted into the through hole 21 from the surface side of the artificial hold 11, and has a large diameter portion 21b, a small diameter portion 21c, a bolt hole 16 of the artificial hold mounting portion 14, a bolt hole of the board mounting portion 15. 16, and further passes through the through hole 26 of the closing plate 25 to reach the nut 27 with a claw. The rotation of the hexagon socket cap bolt 13 causes the hexagon socket cap bolt 13 to enter the claw nut 27. When the head of the hexagon socket cap bolt 13 comes into contact with the step surface 21 a of the through hole 21 by tightening the hexagon socket cap bolt 13, the hexagon socket cap bolt 13 screwed into the claw nut 27 is attached. Through this, the artificial hold 11 is fixed to the board 12 in the determined orientation (see FIG. 6).

That is, between the artificial hold 11 fixed to the board 12 and the board 12, the artificial hold attaching portion 14 and the board attaching portion 15 are engaged with the protrusion 17 and the groove 18 in an engaged state. The locking tool 10 is interposed (see FIG. 6). Also, the artificial hold mounting portion 14
Since the overlapping thickness of the board mounting portion 15 and the board mounting portion 15 is higher than the depth of the circular opening 23, the artificial hold 11 does not come into contact with the board 12 when the hexagon socket head cap bolt 13 is tightened.

As a result, in the artificial hold mounting portion 14 and the board mounting portion 15, since the respective protrusions and the respective grooves are in contact with each other, the effect of suppressing the rotation can be retained. Further, the tightening force generated by screwing the hexagon socket head cap bolt 14 onto the nut 27 with the claw engages with each of the protrusions 17 and the grooves 18 of the artificial hold mounting portion 14 and the board mounting portion 15 respectively. It acts as a rotation blocking force. Therefore, the rotation of the artificial hold 11 can be effectively suppressed.

Since the hexagon socket head cap bolt 13 for fixing the artificial hold 11 to the board 12 is inserted into the through hole 21 of the artificial hold 11 (see FIG. 6), the climber P touches the finger hook portion 19 with a finger. There is no hindrance when hanging. On the other hand, when the inclination angle of the artificial hold 11 is changed, the hexagon socket head cap bolt 13 is rotated in the direction to release the screw joint so that the hexagon socket cap cap bolt 13 and the claw nut 27 are released from the screw joint. . Hexagon socket head cap bolt 13 and claw nut 2
After the screwing with 7 is released, the artificial hold mounting portion 14 is pulled away from the board mounting portion 15, so that the ridges 17 and the grooves 1 of the artificial holding mounting portion 14 and the board mounting portion 15 are separated from each other.
Each meshing state of 8 is eliminated.

After that, after changing the inclination of the artificial hold 11 in order to set the artificial hold 11 in a desired direction, the artificial hold 11 whose direction is determined is fixed to the board 12 again by the hexagon socket cap bolt 13. To do. After that, the direction of the artificial hold 11 can be arbitrarily changed as needed. The shapes of the protrusions and the grooves of the artificial hold attachment portion 14 and the board attachment portion 15 have a triangular cross section,
It may have the following shape. A ridge 31 and a groove 32 having a rectangular cross section shown in FIG. 8, a ridge 33 and a groove 34 having a trapezoidal cross section shown in FIG. 9, and a ridge 35 and a groove 36 having a mountain cross section shown in FIG. The ridge 37 and the groove 38 having the stepwise cross section shown in FIG. 11 may be used. In addition,
In this case, the groove has a shape in which the ridge is turned upside down, and the ridge and the groove are arranged alternately and continuously.

Further, the protrusions and grooves of the artificial hold mounting portion 14 and the board mounting portion 15 may have different sectional shapes. In the artificial hold mounting portion 14, ridges and grooves having different cross-sectional shapes are alternately and continuously arranged, and the board mounting portion 15
Then, the grooves corresponding to the ridges of the artificial hold attaching portion 14 and the ridges corresponding to the grooves are alternately and continuously arranged. For example, FIG.
As shown in FIG. 2, the ridge 39 having a trapezoidal cross section provided on the artificial hold mounting portion 14 and the groove 40 having an inverted triangular cross section, and the board mounting portion 15 corresponding to the ridge 39 and the groove 40, respectively. The groove 41 and the ridge 42 provided may be used.
Further, as shown in FIG. 13, the ridge 43 having a wide rectangular cross section and the groove 44 having a narrow rectangular cross section, which are provided in the artificial hold mounting portion 14, and the ridge 43 and the groove 44 respectively correspond. The groove 45 and the ridge 46 provided on the board mounting portion 15 may be used. Further, as shown in FIG. 14, a protrusion 47 having a triangular cross section provided on the artificial hold attachment portion 14 and a groove 48 having a triangular cross section formed by extending one oblique side 47a of the protrusion 47, The groove 49 and the protrusion 50 may be provided on the board mounting portion 15 so as to correspond to the groove 47 and the groove 48, respectively.

Further, each protrusion has an artificial hold mounting portion 14

Further, only one of the divided pieces may be used. The same applies to each groove.
Further, as shown in FIG. 15, instead of the protrusions and the grooves, the convex portions 51 located on the circumference along the peripheral edge (see FIG. 15A).
Alternatively, a concave portion 52 (see FIG. 15B) corresponding to the convex portion 51 may be formed. In this case, the number of steps in which the orientation can be changed is determined by the number of the convex portions 51 and the concave portions 52 arranged at a predetermined distance. The shape of the convex portion 51 can be formed into various shapes such as a spherical shape, a cylindrical shape, a prismatic shape, a conical shape, and a pyramidal shape. At this time, the concave portion 52 is also formed corresponding to various shapes of the convex portion 51.

Further, as shown in FIG.
A plurality of them may be arranged at intervals in the radial direction. At this time, the concave portion is also formed corresponding to the convex portion. That is, in the artificial hold mounting portion 14, adjacent ridges or grooves (or convex portions or concave portions) are formed at substantially equal intervals, and the board mounting portion 15 that meshes and locks with the artificial hold mounting portion 14 is also formed. The intervals between the adjacent ridges or grooves (or the protrusions or recesses) are formed at substantially equal intervals.
