Summary of the Invention

Problems to be Solved by the Invention

[0004] In the configuration of the above Patent Document 1, when attaching the mounting bracket to the ridge portion, the second clamping member needs to enter the ridge portion between the first contact portion of the first clamping member and the second contact portion of the second clamping member while maintaining an open state with respect to the first clamping member, which is troublesome. As an example, when attaching the mounting bracket to the ridge portion, the operator needs to use both hands to enter the ridge portion between the first contact portion of the first clamping member and the second contact portion of the second clamping member while maintaining an open state of the second clamping member with respect to the first clamping member, and then switch to a tool for tightening the bolts and nuts.

[Modes for carrying out the invention]

[0009] One embodiment of the mounting device according to the present invention will be described with reference to the drawings. As shown in Figure 5(c), the mounting fixture 10 is made of metal and is attached to the seam portion 80 of the folded-sheet metal roof. The outer frame portion of a solar panel 60, which is an example of the object to be supported, is installed on the upper surface of the mounting fixture 10. As shown in Figures 5(a) and (b), either an end retaining member 71 or an intermediate retaining member 72 is selectively attached to the mounting fixture 10. The end retaining member 71 and the intermediate retaining member 72 press down on the outer frame portion of the solar panel 60 installed on the upper surface of the mounting fixture 10 from above. Multiple mounting fixtures 10 are installed along the outer circumference of one solar panel 60. As shown in Figure 5(b), the intermediate retaining member 72 is attached to the mounting fixture 10 located between two solar panels 60a and 60b, for example, when two solar panels 60a and 60b are placed side by side. The intermediate retaining member 72 presses down on the outer frame portions of each of the two solar panels 60a and 60b from above. As shown in Figure 5(a), the end retaining member 71 is attached to the mounting fixture 10 on the outer periphery side of the solar panel 60 where no other solar panels are adjacent. The end retaining member 71 presses down on the outer periphery frame of the solar panel 60 from above.

[0010] Next, we will describe the mounting fixture 10. As shown in Figures 1(a) and 1(b), the mounting device 10 comprises a first clamping member 20 having a contact portion 22a, a second clamping member 30 having a contact portion 32a, a fastening portion 40, and a mounting shaft portion 50. The first clamping member 20 and the second clamping member 30 are configured to rotate relative to each other around the pivot axis J when a fastening force is applied by the fastening portion 40 using a tool, and are configured to clamp the seam portion 80 (see Figure 5(c)) from both sides by a pair of contact portions 22a and 32a. In the following explanation, the direction in which the pair of contact portions 22a and 32a are aligned is defined as the width direction W, the direction perpendicular to the width direction W and along the pivot axis J is defined as the length direction L, and the direction perpendicular to both the width direction W and the length direction L is defined as the height direction H.

[0011] (First clamping member 20) As shown in Figures 1(a) and 1(b), the first clamping member 20 comprises a panel support portion 21, a side wall portion 22, a locking portion 25, and an alignment recess 24. The panel support portion 21 is rectangular in shape along the width direction W and the length direction L; in this example, it is rectangular in shape with the length direction L being longer. The outer frame portions of the solar panels 60, 60a, and 60b (see Figures 5(a) and (b)) are installed on the upper surface of the panel support portion 21. As shown in Figure 2(a), a hole 21h is formed in the center of the panel support portion 21 through which the mounting shaft portion 50 passes. The mounting shaft portion 50 comprises a bolt 50b inserted through the hole 21h and a nut 50n screwed onto the shaft portion of the bolt 50b. The panel support portion 21 is sandwiched between the head 50t of the bolt 50b and the nut 50n. As shown in Figures 5(a) and (b), an end retaining member 71 or an intermediate retaining member 72 is inserted through the bolt 50b, and a nut 51n, separate from the nut 50n, is screwed onto it. The nut 51n presses the end retaining member 71 or the intermediate retaining member 72 against the outer frame portion of the solar panels 60, 60a, and 60b. As shown in Figures 1(a) and 1(b), multiple line sections 211 to 216 are formed on the upper surface of the panel support section 21. Each line section 211 to 216 is formed as a line extending in the width direction W, for example, by engraving. Three line sections 211 to 213 are located on one end of the upper surface of the panel support section 21 in the width direction W (left side in Figures 1(a) and 1(b)) and are aligned in the length direction L. Three line sections 214 to 216 are located on the other end of the upper surface of the panel support section 21 in the width direction W (right side in Figures 1(a) and 1(b)) and are aligned in the length direction L. The two line sections 212 and 215 are aligned in the width direction W and are positioned in the length direction L corresponding to the center of the bolt 50b. The two line sections 212 and 215 serve as markers indicating the center in the length direction L of the mounting fixture 10. The two line sections 211 and 214 are aligned in the width direction W and are located on one side of the two line sections 212 and 215 in the length direction L. The two line sections 211 and 214 serve as markers for positioning the side of the outer frame of the solar panel 60b (see Figure 5(b)). The two line portions 213 and 216 are arranged in the width direction W and are located on the other side of the two line portions 212 and 215 in the length direction L. The two line portions 213 and 216 are marks for positioning the side surface of the outer peripheral frame portion of the solar panel 60a (see FIG. 5(b)).

[0012] As shown in FIGS. 1(a) and (b), the side wall portion 22 extends in a direction intersecting the panel support portion 21, in this example, in a perpendicular direction, and forms a substantially J-shaped plate when viewed from the length direction L. The side wall portion 22 is connected to the end portions of both ends of the panel support portion 21 in the width direction W on the side opposite to the locked portion 25.

[0013] The alignment recess 24 is located at the end portion of the panel support portion 21 on the side opposite to the side wall portion 22 in the width direction W. The alignment recess 24 is formed by recessing the upper corner portion of the corresponding end portion of the panel support portion 21 in a concave shape so that an operator can visually recognize it from the outside. As shown in FIG. 4, the alignment recess 24 includes a contact surface 24a extending along the length direction L.

[0014] As shown in FIG. 1(a), a locking portion 35 of the second clamping member 30 is locked to the locked portion 25 so as to be rotatable about the rotation axis J. The locked portion 25 is located at the end portion of the panel support portion 21 on the side opposite to the side wall portion 22. The locked portion 25 is located below the alignment recess 24.

[0015] As shown in FIGS. 3(a) and (b), the locked portion 25 includes a main body portion 25a, a claw portion 25t which is an example of an opening holding portion, and a retaining portion 25n. The main body portion 25a has a U-shaped cross section opening outward in the width direction W. Inside the main body portion 25a, a locking portion 35 of the second clamping member 30 described later is configured to be able to enter.

[0016] The claw portion 25t holds the first clamping member 20 and the second clamping member 30 in an open state (see Fig. 2(a)) or a closed state (see Fig. 2(b)). In the state of being held in the open state or the closed state, the claw portion 25t is hooked on the locking portion 35 of the second clamping member 30, so that the rotation of the second clamping member 30 about the rotation axis J with respect to the first clamping member 20 is restricted. This restriction of rotation cannot be released by the force of a human hand and is set to be rotatable by the force using a tool. In the open state, the gap Sk between the pair of abutting portions 22a and 32a is larger than the length in the width direction W of the crack portion 80. In the closed state, the gap Sk between the pair of abutting portions 22a and 32a is smaller than in the open state, and the pair of abutting portions 22a and 32a are in a state of approaching or contacting each other.

[0017] As shown in Fig. 4, the claw portion 25t is located inside the main body portion 25a and, in this example, is positioned as a convex portion on the lower surface inside the main body portion 25a. The claw portion 25t is located at the center in the length direction L inside the main body portion 25a. The claw portion 25t forms a triangle when viewed from the length direction L. As shown in Fig. 3(a), the claw portion 25t includes a first inclined surface 25t1 located on the opening side of the main body portion 25a and a second inclined surface 25t2 located on the depth side inside the main body portion 25a. The first inclined surface 25t1 holds the above-described open state by sandwiching the locking portion 35 with the retaining portion 25n. The claw portion 25t is formed, for example, by bending a part of the lower plate portion of the main body portion 25a of the locked portion 25 upward.

[0018] The retaining portion 25n is located at the upper opening end of the main body portion 25a and defines a gap into which the locking portion 35 enters between the retaining portion 25n and the claw portion 25t. As shown in Fig. 4, the retaining portion 25n is formed over the entire length direction L of the main body portion 25a. As shown in Fig. 3(a) and (b), the retaining portion 25n has a substantially triangular shape with an arcuate corner facing the first inclined surface 25t1 of the claw portion 25t. Specifically, the retaining portion 25n includes a curved portion 25n1 facing the first inclined surface 25t1 of the claw portion 25t and an inclined surface 25n2 facing the opening side of the main body portion 25a. The inclined surface 25n2 inclines toward the depth side inside the main body portion 25a as it approaches the curved portion 25n1.

[0019] As shown in Figures 1(a) and 1(b), the side wall portion 22 comprises a main body portion 22d having a contact portion 22a, a protruding portion 22b, and a bolt head housing portion 22c. The main body portion 22d is roughly J-shaped and is symmetrical (left-right symmetrical) with the second clamping member 30, which is also roughly J-shaped, in the width direction W, and is formed to face the second clamping member 30. The contact portion 22a is located on the tip side of the roughly J-shaped main body portion 22d. As shown in Figures 2(a) and (b), the contact portion 22a has a trapezoidal cross-section with the base and top sides aligned in the width direction W. On the surface of the contact portion 22a facing the contact portion 32a (the top side of this trapezoidal cross-section), a plurality of grooves are formed in a sawtooth pattern aligned in the height direction H. These multiple grooves are formed to make the clamping to the seam portion 80 stronger. The lower end surface of the main body portion 22d has a flat portion 22e that is planar.

[0020] The protruding portion 22b is located on the lower end side of the main body portion 22d and protrudes in the width direction W on the opposite side from the contact portion 22a. The protruding portion 22b has a shape in which its thickness decreases as it moves away from the contact portion 22a in the width direction W. The lower surface of the protruding portion 22b is on the same plane as the flat portion 22e of the main body portion 22d. The lower surface of the protruding portion 22b and the flat portion 22e allow the mounting device 10 to stand on its own during operation. The protruding portion 22b prevents the mounting device 10 from tipping over during operation.

[0021] As shown in Figure 2(a), the bolt head housing portion 22c is provided on the outer surface of the side wall portion 22 (the back surface of the side wall portion 22 corresponding to the second clamping member 30) and houses the head 40t of the bolt 40b of the fastening portion 40, which will be described later. The bolt head housing portion 22c extends along the length direction L and has two wall portions that face each other so as to sandwich the head 40t. The bolt head housing portion 22c prevents the bolt 40b from tilting. A bolt through hole 22h is formed inside the bolt head housing portion 22c of the side wall portion 22 through which the shaft portion of the bolt 40b of the fastening portion 40 passes.

[0022] (Second clamping member 30) As shown in Figures 1(a) and (b), the second clamping member 30 comprises a side wall portion 32, a locking portion 35, and an alignment projection portion 34. The side wall portion 32 is a plate shape that is approximately J-shaped when viewed from the length direction L. The length of the side wall portion 32 in the height direction H is the same as the length of the side wall portion 22 of the first clamping member 20 in the height direction H. The length of the side wall portion 32 in the length direction L is shorter than the length of the side wall portion 22 of the first clamping member 20 in the length direction L. A bolt through hole 32h is formed in the flat plate portion of the side wall portion 32 through which a bolt 40b of the fastening portion 40, described later, is inserted. The bolt through hole 32h is formed as an elongated hole that is long in the height direction H. As a result, with the bolt 40b inserted through the bolt through hole 32h, the second clamping member 30 can rotate relative to the first clamping member 20 around the pivot axis J.

[0023] The side wall portion 32 includes a contact portion 32a and a protruding portion 32b. As shown in Figure 2(b), in the closed state, the contact portion 32a and the protruding portion 32b are symmetrical in the width direction W with respect to the contact portion 22a and the protruding portion 22b of the first clamping member 20 described above, and have the same shape and function as the contact portion 22a and the protruding portion 22b. For this reason, a detailed explanation of the contact portion 32a and the protruding portion 32b is omitted.

[0024] As shown in Figures 2(a) and 2(b), the locking portion 35 is located on the upper inner surface of the side wall portion 32 and has an L-shape with a curved corner. As shown in Figures 3(a) and 3(b), the locking portion 35 comprises a first side portion 35a and a second side portion 35b. The first side portion 35a extends from the inner surface of the side wall portion 32 along the width direction W. A recess 35c is formed on the lower surface of the first side portion 35a. An inclined surface 35d is formed on the second side portion 35b side of the recess 35c. The inclined surface 35d is a slope that smoothly connects the inside and outside of the recess 35c and is the surface on which the claw portion 25t slides during the transition between the closed and open states. The second side portion 35b is connected to the end of the first side portion 35a that is far from the inner surface of the side wall portion 32 and extends upward. The inner and outer corners of the first side 35a and the second side 35b are curved. The pivot axis J of the first clamping member 20 is located at the connecting portion of the first side 35a and the second side 35b. As shown in Figure 3(a), when the first clamping member 20 and the second clamping member 30 are open, the connecting portion of the first side 35a and the second side 35b is clamped from the thickness direction between the retaining portion 25n and the claw portion 25t. Furthermore, in this state, even if an external force such as its own weight applies a rotational moment to the second clamping member 30 in the clockwise direction in the figure, centered on the pivot axis J, the rotation of the second clamping member 30 in that clockwise direction is restricted because the second side 35b catches on the retaining portion 25n. On the other hand, by applying a rotational moment to the second clamping member 30 in the counterclockwise direction in the figure, the locking portion 35 can be removed from the locked portion 25. As shown in Figure 3(b), when the first clamping member 20 and the second clamping member 30 are in the closed position, the second side portion 35b contacts the inner bottom surface 25b (the left side surface in Figure 3(b)) of the U-shaped main body portion 25a.

[0025] As shown in Figure 3(a), an inclined surface 38 is formed between the base end of the first side portion 35a (the end opposite to the second side portion 35b) and the alignment projection 34. The inclined surface 38 is inclined so that it approaches the second side portion 35b as it extends downward. As shown in Figure 3(b), when the first clamping member 20 and the second clamping member 30 are in the closed state, the inclined surface 38 contacts the inclined surface 25n2 of the retaining portion 25n. As a result of the contact between the inclined surface 38 and the inclined surface 25n2, a force F1 acts in the closed state, pushing the second clamping member 30 downward.

[0026] As shown in Figures 1(a) and 1(b), the alignment projection 34 is located at the upper end of the side wall 32 so that it can be seen by an operator from the outside, and extends toward the panel support 21 in a direction perpendicular to the side wall 32. As shown in Figure 3(a), the alignment projection 34 has a contact surface 34a located on the tip side of the alignment projection 34. As the transition from the open state to the closed state of the first clamping member 20 and the second clamping member 30 progresses, the gap between the contact surface 34a of the alignment projection 34 and the contacted surface 24a of the alignment recess 24 becomes smaller, and in the closed state, the contact surface 34a and the contacted surface 24a of the first clamping member 20 and the second clamping member 30 are in surface contact.

[0027] (Fastening part 40) As shown in Figure 2(a), the fastening portion 40 fastens the first clamping member 20 and the second clamping member 30 by applying a fastening force in a direction that brings them closer together. The fastening portion 40 comprises a bolt 40b having a head 40t and a shaft portion 40j, and a nut 40n that is screwed onto the shaft portion 40j. The shaft portion 40j of the bolt 40b is inserted through the bolt through hole 22h of the side wall portion 22 and the bolt through hole 32h of the side wall portion 32, and the head 40t of the bolt 40b is located in the bolt head housing portion 22c. The nut 40n is screwed onto the tip side of the shaft portion 40j that has passed through the bolt through hole 32h of the side wall portion 32. When the nut 40n is rotated, the nut 40n pushes the second clamping member 30 toward the head 40t, thereby causing the second clamping member 30 to rotate toward the first clamping member 20 around the pivot axis J.

[0028] (Installation method) Next, we will explain how to attach the mounting fixture 10 to the seam portion 80. Before attaching the mounting fixture 10 to the seam portion 80, the first clamping member 20 and the second clamping member 30 of the mounting fixture 10 are held in an open state, as shown in Figure 2(a). The mounting fixture 10 is shipped in an open state and transported to the installation site. In this open state, the seam portion 80 is positioned in the gap Sk between the pair of contact portions 22a and 32a. At this time, the claw portion 25t is held in an open state by catching on the locking portion 35 of the second clamping member 30, so the worker can handle the mounting fixture 10 with one hand while holding a tool (electric screwdriver) with the other hand. The worker then rotates the nut 40n with the tool, rotating the first clamping member 20 around the pivot axis J so that the contact portion 32a approaches the contact portion 22a, while linearly moving the first clamping member 20 in the width direction W so that it approaches the second clamping member 30. At this time, as shown in Figure 3(a), the locking portion 35 slides on the first inclined surface 25t1 of the claw portion 25t and rides up onto the claw portion 25t. At this time, the claw portion 25t is deformed downward by being pushed by the locking portion 35, or the claw portion 25t and the locking portion 35 wear each other down due to friction. Then, as shown in Figure 3(b), the locking portion 35 slides on the claw portion 25t and moves toward the inner bottom surface 25b, making contact with the inner bottom surface 25b, the contact surface 34a of the alignment projection 34 makes surface contact with the contacted surface 24a of the alignment recess 24, and the inclined surface 38 makes contact with the inclined surface 25n2 of the retaining portion 25n. As a result, the first clamping member 20 and the second clamping member 30 are in a closed state. At this time, the claw portion 25t is located inside the recess 35c and is pressed against the upper surface of the recess 35c. The operator can visually observe the degree of progress from the open state to the closed state by the size of the gap between the contact surface 34a of the alignment projection 34 and the contacted surface 24a of the alignment recess 24, and can also visually observe the inclination of the second clamping member 30 relative to the first clamping member 20 by the degree of parallelism between the contact surface 34a and the contacted surface 24a. Furthermore, the torque required to rotate the nut 40n with a tool is large until the locking portion 35 has climbed the first slope 25t1 of the claw portion 25t, and then decreases after it has climbed the first slope 25t1. Achieving such torque changes makes the work smoother.When the first clamping member 20 and the second clamping member 30 are closed, the pair of contact portions 22a and 32a are pressed against the seam portion 80 in a direction that brings them closer together, and the seam portion 80 is clamped between the pair of contact portions 22a and 32a. As a result, the mounting device 10 is fixed to the seam portion 80. This concludes the explanation of how to attach the mounting fixture 10 to the seam portion 80.

[0029] Even if the fastening force of the fastening part 40 decreases after the mounting device 10 has been attached to the seam portion 80, the claw portion 25t will catch on the locking portion 35, maintaining the state in which the seam portion 80 is clamped between the pair of contact portions 22a and 32a. Therefore, the mounting device 10 is prevented from falling off the seam portion 80. Examples of situations in which the fastening force of the fastening part 40 decreases include, for example, when the nut 40n loosens over time, or when the mounting device 10 is reattached. Furthermore, when removing the mounting fixture 10 from the seam portion 80, after removing the fastening portion 40, force is applied to the mounting fixture 10 using a tool such as a hammer or crowbar, which releases the claw portion 25t from being caught in the locking portion 35. This causes the mounting fixture 10 to open, releasing the seam portion 80 from being clamped between the pair of contact portions 22a and 32a. At this time, as shown in Figures 3(a) and (b), since an inclined surface 35d is formed in the recess 35c, the claw portion 25t can easily move from inside the recess 35c to outside the recess 35c, making it easier to transition from the closed state to the open state.

[0030] (effect) According to the embodiment described above, the following effects are achieved. (1) The mounting device 10, which is attached to a seam portion 80, is an example of a mounting portion, and comprises a first clamping member 20 and a second clamping member 30 formed to be able to clamp the seam portion 80. The first clamping member 20 and the second clamping member 30 are provided with a pair of contact portions 22a and 32a that abut against both sides of the seam portion 80 in the width direction W when the seam portion 80 is clamped, and are configured to be rotatable around a pivot axis J between an open state in which the pair of contact portions 22a and 32a are separated from each other, and a closed state in which the pair of contact portions 22a and 32a are closer to each other than in the open state or are in contact with each other. The mounting device 10 is provided with a claw portion 25t, which is an example of an open-holding portion that restricts the rotation of the first clamping member 20 and the second clamping member 30 around the pivot axis J while holding the first clamping member 20 and the second clamping member 30 in the open state. With this configuration, the first clamping member 20 and the second clamping member 30 are held in an open state, so the worker does not need to hold them in an open state when attaching the mounting device 10 to the seam portion 80. Therefore, the mounting device 10 can be attached to the seam portion 80 more easily.

[0031] (2) The mounting fixture 10, when attached to the seam portion 80, supports the solar panel 60 together with an end retaining member 71 or an intermediate retaining member 72, which are examples of retaining members attached to the mounting fixture 10. The claw portion 25t is set so that the length of the gap Sk between the pair of contact portions 22a and 32a in the open state is greater than the length W in the width direction of the seam portion 80. With this configuration, when installing the mounting fixture 10, the seam portion 80 can be easily inserted into the gap Sk between the pair of contact portions 22a and 32a. Here, the length W in the width direction of the seam portion 80 refers to the maximum length W in the width direction of the seam portions 80 of multiple types of roofs to which the mounting fixture 10 is to be installed.

[0032] (3) The mounting device 10 includes a fastening portion 40 that fastens the first clamping member 20 and the second clamping member 30 so that the first clamping member 20 and the second clamping member 30 clamp the seam portion 80. The fastening portion 40 includes a bolt 40b that extends in a width direction W perpendicular to the pivot axis J and is inserted through the first clamping member 20 and the second clamping member 30, and a nut 40n that is screwed onto the tip side of the bolt 40b and rotated, thereby applying a force between the bolt 40b and the head 40t that brings the first clamping member 20 and the second clamping member 30 closer to each other. The first clamping member 20 includes a locking portion 25 formed in the shape of a groove that extends in a length direction L along the pivot axis J. The second clamping member 30 includes a locking portion 35 that locks to the locking portion 25 so as to be rotatable relative to each other around the pivot axis J. The claw portion 25t is formed within the locked portion 25 and, by contact with the locking portion 35, holds the first clamping member 20 and the second clamping member 30 in an open state. When the first clamping member 20 and the second clamping member 30 are in the open state, if the nut 40n is rotated by a tool, the locking portion 35 overcomes the claw portion 25t and closes the clamping member 20 and the second clamping member 30. With this configuration, a simple setup is used, and before fastening by the fastening portion 40, the first clamping member 20 and the second clamping member 30 are held in an open state, and the nut 40n can be rotated with a tool to transition from the open state to the closed state.

[0033] (4) The claw portion 25t has a closing function that maintains the closed state in which the pair of contact portions 22a and 32a hold the seam portion 80, even if the fastening state by the fastening portion 40 is released, by maintaining the state in which it is hooked onto the locking portion 35. With this configuration, even if the fastening force of the fastening part 40 decreases due to, for example, the loosening of the nut 40n, the closed state in which the seam part 80 is held between the pair of contact parts 22a and 32a is maintained.

[0034] (5) The first clamping member 20, which is either the first clamping member 20 or the second clamping member 30, is formed on the upper side of the mounting device 10 and has a contact surface 24a that extends along the pivot axis J. The second clamping member 30, which is the other of the first clamping member 20 or the second clamping member 30, is formed on the upper side of the mounting device 10 and has a contact surface 34a that makes surface contact with the contact surface 24a as the gap Sk with the contact surface 24a decreases as the transition from the open state to the closed state progresses. With this configuration, the worker can visually check the size of the gap between the contact surface 34a of the alignment projection 34 and the contacted surface 24a of the alignment recess 24 to confirm the degree of progress from the open state to the closed state. In addition, the degree of parallelism between the contact surface 34a and the contacted surface 24a allows the worker to check the inclination between the first clamping member 20 and the second clamping member 30. Therefore, the worker can easily confirm that the mounting device 10 has been accurately attached to the seam portion 80.

[0035] However, the present invention is not limited to the embodiments and drawings described above. Modifications (including the deletion of components) can be made as appropriate without altering the essence of the invention. An example of a modification is described below.

[0036] (modified version) In the above embodiment, the mounting device 10 was attached to the seam portion 80, but it is not limited to this and may be attached to other roof members or frame members other than the roof. The mounting fixture 10 supported the solar panel 60 together with the end retaining member 71 or the intermediate retaining member 72, but it may also support structures other than the solar panel 60.

[0037] In the above embodiment, there was one claw portion 25t, but there may be multiple. Furthermore, the claw portion 25t may be formed over the entire length L within the main body portion 25a. In the above embodiment, the claw portion 25t was integrally formed with the main body portion 25a, but it is not limited to this and may be formed separately from the main body portion 25a. Furthermore, the claw portion 25t may be formed from a different material than the main body portion 25a, for example, rubber or resin.

[0038] In the above embodiment, the claw portion 25t was located on the lower surface of the main body portion 25a, but it may be provided in a different position. For example, the claw portion 25t may be located on the upper surface of the main body portion 25a. In the above embodiment, the claw portion 25t was triangular when viewed from the longitudinal direction L, This is not limited to these shapes; they may also be rectangular (such as a trapezoid), semicircular, or other shapes. In the above embodiment, the claw portion 25t may be configured to bend when the first clamping member 20 and the second clamping member 30 transition from an open state to a closed state, by the locking portion 35. Furthermore, in addition to the claw portion 25t, a spring such as a coil spring or a leaf spring may be used as the open-holding portion, and this spring may hold the first clamping member 20 and the second clamping member 30 in the open state by its own elastic force (restoring force).

[0039] In the above embodiment, the second clamping member 30 was configured to be rotatable around the pivot axis J relative to the first clamping member 20 while the locking portion 35 was locked to the locked portion 25. However, the configuration is not limited to this, as long as it is rotatable, for example, it may be configured to be rotatable around the pivot axis J relative to the first clamping member 20 by means of a hinge.

[0040] In the above embodiment, a recess 35c having an inclined surface 35d was formed on the lower surface of the locking portion 35, but the inclined surface 35d may be omitted, and furthermore, the recess 35c may be omitted. In the above embodiment, the claw portion 25t had both an open-holding function to hold the first clamping member 20 and the second clamping member 30 in an open state and a closed-holding function to hold the first clamping member 20 and the second clamping member 30 in a closed state. However, it is not limited to this, and a claw portion with an open-holding function and a claw portion with a closed-holding function may be provided separately. In the above embodiment, the first clamping member 20 was provided with a locking portion 25 and the second clamping member 30 was provided with a locking portion 35. However, conversely, the first clamping member 20 may be provided with a locking portion 35 and the second clamping member 30 may be provided with a locking portion 25. The line sections 211 to 216 in the above embodiment may be omitted. [Explanation of Symbols]
