Fig. 15 is a schematic perspective view showing fastener 1A in a fifth modified example of the first embodiment.

[0015] As illustrated in FIG. 1, a fixing device 1A in the first embodiment includes a gripping member 2 capable of gripping an object B, a lever 3, a pressing member 4, and an operating member 5.

[0016] The gripping member 2 has a first gripping portion 21 and a second gripping portion 22. The object B is gripped by the first gripping portion 21 and the second gripping portion 22, and thereby the fixing device 1A is fixed to the object B.

[0017] The lever 3 can pull the second gripping portion 22 in a first direction DR1 toward the first gripping portion 21. When the lever 3 pulls the second gripping portion 22 in the first direction DR1, the distance between the first gripping portion 21 and the second gripping portion 22 decreases. In the example shown in FIG. 2 , the gripping member 2 (e.g., the region indicated by the arrow AR) elastically deforms, thereby decreasing the distance between the first gripping portion 21 and the second gripping portion 22. Alternatively, the entire gripping member 2 may elastically deform.

[0018] The pressing member 4 moves in a second direction DR2 different from the first direction DR1 to press the lever 3. In the example shown in Fig. 2, the second direction DR2 is perpendicular to the first direction DR1.

[0019] The pressing member 4 presses the lever 3, thereby moving the lever 3 in the first direction DR1. In the example shown in FIG. 1 , the pressing member 4 has a pressing portion 42 that presses the pressed portion 35 of the lever 3. The pressing force with which the pressing portion 42 presses the pressed portion 35 has a force component F1 in the first direction DR1 in addition to a force component in the second direction DR2. Therefore, when the pressing portion 42 presses the pressed portion 35, the lever 3 moves in the first direction DR1.

[0020] The operating member 5 has an operating portion 53 that is operated by a tool such as a remote-controlled tool or by the user's hand. The operating member 5 also moves the pressing member 4 in the second direction DR2. In the example shown in FIG. 1 , the operating member 5 has a second contact portion 52 that comes into contact with the first contact portion 44 of the pressing member 4. When the operating portion 53 is operated in the first operating direction MR1, the second contact portion 52 presses the first contact portion 44 in the second direction DR2. As a result, the pressing member 4 moves in the second direction DR2.

[0021] (operation) In the example shown in FIG. 1 , when the operating portion 53 is operated in a first operating direction MR1, the operating member 5 moves the pressing member 4 in a second direction DR2. When the pressing member 4 moves in the second direction DR2, the lever 3 moves in a first direction DR1 that is different from the second direction DR2. When the lever 3 moves in the first direction DR1, the lever 3 pulls the second gripping portion 22 in the first direction DR1, and the distance between the first gripping portion 21 and the second gripping portion 22 decreases (see FIG. 2 ). In this way, the object B placed between the first gripping portion 21 and the second gripping portion 22 is gripped by the first gripping portion 21 and the second gripping portion 22.

[0022] 2, when the operating unit 53 is operated in the second operating direction MR2, (1) the force of the gripping member 2 returning to its original shape causes the second gripping unit 22 to move in the third direction DR3 (in other words, in the direction away from the first gripping unit 21), (2) the lever 3 to move in the third direction DR3, and (3) the pressing member 4 to move in the fourth direction DR4. In this way, the grip of the object B by the first gripping unit 21 and the second gripping unit 22 is released (see FIG. 1).

[0023] In the first embodiment, the fixing device 1A can be easily fixed to the object B by utilizing the movement of the pressing member 4 and the lever 3. Furthermore, since the direction of movement of the pressing member 4 (more specifically, the second direction DR2) caused by the operation of the operating unit 53 is different from the direction of movement of the lever 3 (more specifically, the first direction DR1), the degree of freedom in the arrangement of the operating unit 53 is high. For example, the operating unit 53 does not need to be arranged on an extension of the longitudinal direction of the lever 3. In the example shown in FIG. 2, the operating unit 53 is rotatable around the operating axis AX, and the extension direction of the operating axis AX is perpendicular to the first direction DR1. Furthermore, in the example shown in FIG. 2, the operating unit 53 is arranged on the opposite side of the plane PL passing through the lever 3 from the space SP1 in which the object B to be gripped by the gripping member 2 is arranged. It goes without saying that, in the first embodiment, the arrangement of the operating unit 53 in the fixing device 1A is not limited to the example shown in FIG. 2.

[0024] Next, optional additional configurations that can be employed in fixture 1A in the first embodiment will be described.

[0025] (3 rotatable levers) In the example shown in FIG. 3(a), the lever 3 is rotatable about a first axis AX1. More specifically, the lever 3 is movable from a first position P1 to a second position P2 by rotating in a first rotation direction R1 about the first axis AX1. As illustrated in FIG. 3(a), the first position P1 corresponds to a position where the first engagement portion 32 of the lever 3 and the second engagement portion 23 of the second gripping portion 22 are disengaged. Furthermore, as illustrated in FIG. 3(b), the second position P2 corresponds to a position where the first engagement portion 32 of the lever 3 and the second engagement portion 23 of the second gripping portion 22 are engaged with each other.

[0026] In the example shown in Figure 3(b), the lever 3 can be moved from the second position P2 to the first position P1 by rotating in the second rotation direction R2 around the first axis AX1 (in other words, the direction opposite to the first rotation direction R1).

[0027] When the lever 3 is in the first position P1, the object B (in other words, the object to be grasped) can be inserted into the gripping member 2, and the gripping member 2 can be removed from the object B. On the other hand, when the lever 3 is in the second position P2, the fixing device 1A is prevented from falling off the object B (in other words, the object to be grasped).

[0028] (operation) In the example shown in Figure 3(a), when the operating portion 53 is operated in the first operating direction MR1, the lever 3 moves from a first position P1 where the engagement between the first engagement portion 32 and the second engagement portion 23 is released to a second position P2 (see Figure 3(b)) where the first engagement portion 32 and the second engagement portion 23 are engaged with each other.

[0029] 1, after the lever 3 has moved to the second position P2, the operating unit 53 is operated in the first operating direction MR1, thereby moving the lever 3 in the first direction DR1. More specifically, in the example shown in FIG. 1, when the operating member 5 is operated in the first operating direction MR1, the operating member 5 moves the pressing member 4 in the second direction DR2. When the pressing member 4 moves in the second direction DR2, the lever 3 moves in the first direction DR1, which is different from the second direction DR2. When the lever 3 moves in the first direction DR1, the lever 3 pulls the second gripping portion 22 in the first direction DR1, thereby reducing the distance between the first gripping portion 21 and the second gripping portion 22 (see FIG. 2).

[0030] 1 to 3, simply operating the operating unit 53 in the first operating direction MR1 can engage the first engagement portion 32 with the second engagement portion 23 and move the lever 3 in the first direction DR1. In other words, simply operating the operating unit 53 in the first operating direction MR1 successively engages the first engagement portion 32 with the second engagement portion 23 and moves the lever 3 in the first direction DR1. When the lever 3 moves in the first direction DR1, the lever 3 pulls the second gripping portion 22 in the first direction DR1. Pulled in the first direction DR1, the second gripping portion 22 is displaced toward the first gripping portion 21 (see FIG. 2). In this way, the fastener 1A is fixed to the object B.

[0031] As described above, in the example shown in FIGS. 1 to 3, the task of fixing fixture 1A to object B can be carried out efficiently and easily.

[0032] (Rotating guide 26) In the example shown in FIG. 4(a), the fixture 1A includes a rotation guide 26 that guides the rotation of the lever 3 about the first axis AX1.

[0033] 4(a) and 5(a), when the longitudinal direction of the lever 3 is non-parallel to the first direction DR1, the rotation guide 26 restricts or prohibits the lever 3 from moving in a direction parallel to the longitudinal direction of the lever 3. In this case, when the lever 3 rotates around the first axis AX1, the distance between the first axis AX1 and the first engagement portion 32 is maintained substantially constant. Therefore, the rotation of the lever 3 allows the first engagement portion 32 to smoothly engage with the second engagement portion 23.

[0034] 4(b) and 5(b), when the longitudinal direction of the lever 3 is parallel to the first direction DR1, the rotation guide 26 allows the lever 3 to move in a direction parallel to the longitudinal direction of the lever 3. In the examples shown in FIGS. 5(b) and 5(c), when the longitudinal direction of the lever 3 is parallel to the first direction DR1, the rotation guide 26 allows the lever 3 to move relative to the first axis AX1 in a direction parallel to the first direction DR1.

[0035] 4(b) and 4(c), the rotation guide 26 is disposed in a position that does not prevent the lever 3 from moving in the first direction DR1 when the longitudinal direction of the lever 3 is parallel to the first direction DR1. In the example shown in FIG. 4(b), when the lever 3 moves in the first direction DR1, the first engagement portion 32 provided on the tip end 31 of the lever 3 also moves in the first direction DR1 (see FIG. 4(c)). In this way, the second engagement portion 23 that engages with the first engagement portion 32 is pulled in the first direction DR1.

[0036] In the example shown in FIG. 5(a), the rotation guide 26 contacts the outer peripheral surface 34t of the base end 34 of the lever 3. The rotation guide 26 may include a first rotation guide 26a that contacts the outer peripheral surface 34t of the base end 34 of the lever 3 and a second rotation guide 26b that contacts the outer peripheral surface 34t of the base end 34 of the lever 3. When the rotation guide 26 includes the first rotation guide 26a and the second rotation guide 26b, the lever 3 can be rotated around the first axis AX1 with the center portion of the base end 34 of the lever 3 positioned on the first axis AX1. In the example shown in FIG. 5(a), in a cross section perpendicular to the first axis AX1, the outer peripheral surface of the first rotation guide 26a has a curved shape 261a that is convex toward the outer peripheral surface 34t of the base end 34 of the lever 3, and the outer peripheral surface of the second rotation guide 26b has a curved shape 261b that is convex toward the outer peripheral surface 34t of the base end 34 of the lever 3. In a cross section perpendicular to the first axis AX1, the outer circumferential surface of the first rotation guide 26a may have a circular shape, and the outer circumferential surface of the second rotation guide 26b may also have a circular shape.

[0037] 5(b), the rotation guide 26 (more specifically, the first rotation guide 26a and / or the second rotation guide 26b) may have a guide support portion 262 and a roller 263 that is rotatable around the guide support portion 262. Alternatively, the rotation guide 26 may be fixed to the guide support portion so as to be unable to rotate relative to the guide support portion.

[0038] 6(a), the rotation guide 26 may have an arcuate surface 264a that is complementary to the outer peripheral surface 34t of the base end 34 of the lever 3. In the example shown in FIG. 6(a), the rotation guide 26 is composed of only the first rotation guide 26a.

[0039] In the example shown in Figure 5(a), fixture 1A has two rotation guides (26a, 26b), and in the example shown in Figure 6(a), fixture 1A has one rotation guide (26a). Alternatively, fixture 1A may have three or more rotation guides.

[0040] 5(a) and 6(a), when viewed in the direction along the first axis AX1, the outer peripheral surface 34t of the base end 34 of the lever 3 is configured as an arc surface centered on the first axis AX1. In this case, the outer peripheral surface 34t of the base end 34 is smoothly guided by the rotation guide 26.

[0041] (Pressing member 4) In the example shown in FIG. 1 , the pressing member 4 has a pressing portion 42 that presses the pressed portion 35 of the lever 3. The pressing portion 42 has a shape that allows it to press the pressed portion 35 in both the first direction DR1 and the second direction DR2. In this case, when the pressing portion 42 presses the pressed portion 35, the pressing force of the pressing portion 42 has a force component in the first direction DR1 and a force component in the second direction DR2. Therefore, when the pressing portion 42 presses the pressed portion 35, the pressing portion 42 can move the pressed portion 35 in the first direction DR1.

[0042] 7, the pressing member 4 includes a block 40 that is movable relative to the lever 3 in a direction parallel to the second direction DR2. As illustrated in Fig. 2, the block 40 and the pressing portion 42 may be integrally formed. Alternatively, as illustrated in Figs. 8 and 9, the pressing portion 42 may be attached to the block 40 that is movable relative to the lever 3 in a direction parallel to the second direction DR2.

[0043] 7, the pressing member 4 has a through-hole portion 45h into which a shaft 55 described later is inserted. The pressing member 4 may also have a recess 46d that receives a first biasing member 81 described later.

[0044] (First inclined surface 421 and / or second inclined surface 352) In the example shown in FIG. 7, at least one of the pressing portion 42 and the pressed portion 35 has an inclined surface (421, 352) that resolves the pressing force applied by the pressing portion 42 to the pressed portion 35 into a force component in the first direction DR1 and a force component in the second direction DR2.

[0045] In the example shown in FIG. 7 , the pressing member 4 has a first inclined surface 421 that presses the pressed portion 35. The first inclined surface 421 breaks down the pressing force of the pressing member 4 pressing the lever 3 into a force component in the second direction DR2 and a force component in the first direction DR1. In the example shown in FIG. 7 , the first inclined surface 421 is an inclined surface that slopes in the second direction DR2 as it approaches the operating axis AX. In a cross section parallel to both the fifth direction DR5 and the second direction DR2, the first inclined surface 421 may have a linear shape S1 or a curved shape. In other words, the first inclined surface 421 may be formed of a flat surface or a curved surface.

[0046] In the example shown in Fig. 7, the pressed portion 35 of the lever 3 has a second inclined surface 352 that is pressed by the pressing member 4. The second inclined surface 352 resolves the pressing force applied by the pressing member 4 to the lever 3 into a force component in the second direction DR2 and a force component in the first direction DR1. In the example shown in Fig. 7, the second inclined surface 352 is an inclined surface that slopes in the second direction DR2 as it approaches the operating axis AX. In a cross section parallel to both the fifth direction DR5 and the second direction DR2, the second inclined surface 352 may have a linear shape S2 or a curved shape.

[0047] In the example shown in FIG. 7, the pressing portion of the pressing member 4 has a first inclined surface 421 that presses the pressed portion , and the pressed portion has a second inclined surface 352 that is pressed by the pressing portion .

[0048] Alternatively, one of the pressing portion 42 and the pressed portion 35 may have an inclined surface, and the other of the pressing portion 42 and the pressed portion 35 may have any shape that contacts the inclined surface. In the example shown in Fig. 8, the pressed portion 35 has an inclined surface (more specifically, the second inclined surface 352), and the tip of the pressing portion 42 has a hemispherical surface 425 that contacts the inclined surface (more specifically, the second inclined surface 352). Alternatively, the pressing portion 42 may have an inclined surface (more specifically, the first inclined surface 421), and the pressed portion 35 may have a hemispherical surface that contacts the inclined surface.

[0049] 9, the pressed portion 35 may have an inclined surface (more specifically, a second inclined surface 352), and the pressing portion 42 may have a roller 428 that contacts the inclined surface (more specifically, the second inclined surface 352). The roller 428 is supported by the main body portion (more specifically, the block 40) of the pressing member 4 so as to be rotatable about the rotation axis AT. Alternatively, the pressing portion 42 may have an inclined surface (more specifically, a first inclined surface 421), and the pressed portion 35 may have a roller that contacts the inclined surface.

[0050] (Lever 3) 2, the lever 3 has a tip portion 31 and a base portion 34. The base portion 34 of the lever 3 has a pressed portion 35 that is pressed by the pressing portion 42 of the pressing member 4.

[0051] (Second Guide 37) 10 and 11, the lever 3 has a second guide 37 that guides the relative movement of the lever 3 in the first direction DR1 with respect to the pressing member 4. By providing the second guide 37, the lever 3 is smoothly guided in a direction parallel to the first direction DR1. In the example shown in FIG. 4(c), the second guide 37 is two protrusions 37a and 37b arranged on both sides of the pressing member 4. Alternatively, or additionally, the pressing member 4 may have a second guide that guides the relative movement of the lever 3 in the first direction DR1 with respect to the pressing member 4. For example, the pressing member 4 may have two protrusions arranged on both sides of the lever 3.

[0052] Alternatively, the second guide 37 may have a convex portion disposed on one of the lever 3 and the pressing member 4, and a concave portion, a groove, or an elongated hole disposed on the other of the lever 3 and the pressing member 4. In this case, the relative movement of the lever 3 in the first direction DR1 with respect to the pressing member 4 is guided by the convex portion and the concave portion, the groove, or the elongated hole.

[0053] The second guide 37 may prevent the lever 3 from rotating about the first axis AX1 relative to the pressing member 4. Alternatively, a relative rotation prevention portion different from the second guide 37 may prevent the lever 3 from rotating relative to the pressing member 4.

[0054] (First engagement portion 32 and second engagement portion 23) In the example shown in Figure 3(a), the lever 3 (more specifically, the tip 31 of the lever 3) has a first engagement portion 32, and the second grip portion 22 has a second engagement portion 23 that can engage with the first engagement portion 32.

[0055] In the example shown in Fig. 3(a), the first engagement portion 32 is an engagement hook 32k. The engagement hook 32k has, for example, a substantially C-shape. In the example shown in Fig. 3(a), the second engagement portion 23 is formed by an elongated member 23c (for example, a screw member, a pin member, or a screw member and a collar rotatable relative to the screw member).

[0056] 10, the engagement hook 32k has, when viewed in a direction parallel to the second direction DR2, a first opening edge 321 on the distal end portion 31 side, a second opening edge 322 on the proximal end portion 34 side, and a C-shaped inner edge 323 connecting the first opening edge 321 and the second opening edge 322. The C-shaped inner edge 323 preferably has a recess 323d that is recessed toward the distal end portion 31 side relative to the first opening edge 321. In this case, when the second engagement portion 23 of the second gripping portion 22 is engaged with the recess 323d, the second engagement portion 23 is less likely to come off the recess 323d (see FIG. 3(b)).

[0057] 10, the first opening edge 321 and the second opening edge 322 are each substantially linear when viewed in a direction parallel to the second direction DR2. The second opening edge 322 and the C-shaped inner edge 323 are smoothly connected. In this case, the engagement hook 32k can be smoothly removed from the second engagement portion 23 by rotating the lever 3 in the second rotational direction R2 about the first axis AX1.

[0058] (Shaft 55 and elongated hole portion 33h) In the example shown in FIG. 12, the fixture 1A includes a shaft 55 that supports the operating member 5. The shaft 55 extends along the first axis AX1. In the example shown in FIG. 12, the lever 3 has an elongated hole 33h into which the shaft 55 is inserted. The elongated hole 33h allows the lever 3 to move in a direction parallel to the first direction DR1 relative to the shaft 55. As shown in FIG. 10, the major axis of the elongated hole 33h is preferably parallel to the longitudinal direction of the lever 3. With the shaft 55 inserted into the elongated hole 33h, the shaft 55 may function as a rotation guide that guides the rotation of the lever 3 about the first axis AX1 from the inside (see the dashed line in FIG. 10). An inner surface 331h of the elongated hole 33h on the base end 34 side is preferably an arcuate surface having a shape complementary to the outer surface of the shaft 55.

[0059] 12, the shaft 55 has a shaft body 550 and a collar 551 disposed between the shaft body 550 and the elongated hole portion 33h. The collar 551 reduces the frictional force that the elongated hole portion 33h receives from the shaft 55 when the lever 3 rotates around the first axis AX1.

[0060] (Support part 27) In the example shown in FIG. 12, fixture 1A includes support portion 27 that supports lever 3. In the example shown in FIG. 12, support portion 27 is attached to first grip portion 21. Alternatively, support portion 27 and first grip portion 21 may be formed integrally. In other words, support portion 27 may be part of first grip portion 21. Furthermore, support portion 27 may be formed with hole 27h into which part of shaft 55 can be inserted.

[0061] (Washer 71) In the example shown in FIG. 12, the fixing device 1A includes a washer 71 disposed between the support portion 27 and the lever 3. The washer 71 reduces the frictional force that the lever 3 receives from the support portion 27 when the lever 3 rotates around the first axis AX1. More specifically, the washer 71 reduces the frictional force between the lever 3 and the washer 71 compared to the frictional force between the operating member 5 and the pressing member 4. Therefore, when the fixing device 1A includes the washer 71, slippage is less likely to occur between the operating member 5 and the pressing member 4 when the operating member 53 is operated in the first operating direction MR1. Thus, when the operating member 53 is operated in the first operating direction MR1, the pressing member 4 and the lever 3 rotate in the first rotational direction R1 (see FIG. 3(a)), and the lever 3 moves smoothly from the first position P1 to the second position P2 (see FIG. 3(b)). The washer 71 is preferably a thrust washer that supports the load received from the lever 3 in the second direction DR2.

[0062] (First biasing member 81) In the example shown in FIG. 12, fixture 1A includes a first biasing member 81 that biases pressing member 4 toward operating member 5. When operating portion 53 is operated in second operating direction MR2, first biasing member 81 moves pressing member 4 relative to lever 3 in fourth direction DR4. When pressing member 4 moves relative to lever 3 in fourth direction DR4, lever 3 becomes movable in third direction DR3. When lever 3 becomes movable in third direction DR3, the pulling force acting from lever 3 on second gripping portion 22 is released (in other words, gripping of object B by gripping member 2 is released).

[0063] Furthermore, the first biasing member 81 increases the frictional force between the pressing member 4 and the operating member 5. Therefore, when the operating unit 53 is operated in the first operating direction MR1, slippage is less likely to occur between the pressing member 4 and the operating member 5. In this way, when the operating unit 53 is operated in the first operating direction MR1, the pressing member 4 and the lever 3 rotate in the first rotational direction R1 (see FIG. 3(a)), and the lever 3 moves smoothly from the first position P1 to the second position P2 (see FIG. 3(b)).

[0064] (Operating member 5) 12, the operating member 5 has an operating part 53 that is rotatable around an operating axis AX. In the example shown in Fig. 12, the operating axis AX coincides with the first axis AX1 (in other words, the rotation axis of the lever 3).

[0065] 12, the operation unit 53 has a through-hole 53h into which a tool such as a remote-controlled tool can be inserted. In other words, the operation unit 53 is an annular operation unit.

[0066] In the example shown in FIG. 12 , the operating member 5 has a female thread portion 5f that screws into the male thread portion 55m of the shaft 55. In this case, when the operating unit 53 is operated in the first operating direction MR1, the operating member 5 moves relative to the shaft 55 in the second direction DR2. As a result, the operating member 5 presses the pressing member 4 in the second direction DR2. Alternatively, the operating member 5 and the shaft 55 may be configured to be rotatable together around the operating axis AX. For example, in a case where the shaft 55 and the support portion 27 that supports the lever 3 are screwed together, the operating member 5 and the shaft 55 may be configured to rotate together relative to the support portion 27 when the operating unit 53 is operated in the first operating direction MR1.

[0067] (Second biasing member 85) As illustrated in FIG. 13 , the fixing device 1A may have a second biasing member 85 that biases the lever 3 in the fifth direction DR5 (in other words, the direction from the tip end 31 toward the base end 34) or the direction opposite to the fifth direction DR5. When the fixing device 1A has the second biasing member 85 that biases the lever 3 in the fifth direction DR5, unintentional disengagement of the first engagement portion 32 of the lever 3 from the second engagement portion 23 of the second gripping portion 22 is prevented or suppressed when the operating unit 53 is operated in the second operating direction MR2. On the other hand, when the fixing device 1A has the second biasing member 85 that biases the lever 3 in the direction opposite to the fifth direction DR5, the first engagement portion 32 of the lever 3 is more likely to disengage from the second engagement portion 23 of the second gripping portion 22 when the operating unit 53 is operated in the second operating direction MR2. Whether the first engagement portion 32 is made difficult to detach from the second engagement portion 23 or whether the first engagement portion 32 is made easy to detach from the second engagement portion 23 is selected depending on, for example, the type of object B to which the fixing device 1A is fixed.

[0068] In the example shown in FIG. 13, the second biasing member 85 is disposed between the lever 3 and the pressing member 4.

[0069] (Elastic deformation of gripping member 2) 2, when second gripping portion 22 is pulled in first direction DR1 by lever 3, second gripping portion 22 is elastically deformed toward first gripping portion 21. Also, in the example shown in FIG. 2, object B is configured to be gripped by first gripping portion 21 and elastically deformed second gripping portion 22.

[0070] 2, the gripping member 2 has a notch 28 that assists the second gripping portion 22 in elastically deforming toward the first gripping portion 21. The notch 28 is disposed, for example, so as to face the space SP1 in which the object B is disposed.

[0071] Instead of making the gripping member 2 elastically deformable, as illustrated in Fig. 14, the second gripping portion 22 may be connected to the first gripping portion 21 so as to be swingable relative to the first gripping portion 21. In the example shown in Fig. 14, the second gripping portion 22 is connected to the first gripping portion 21 via a hinge 29.

[0072] (Wire receiving part 6) 15, the fixture 1A includes a wire receiving portion 6 that can receive an electric wire W. The wire receiving portion 6 has a receiving portion main body 61 and an opening / closing member 64.

[0073] The receiving portion main body 61 defines a space SP2 in which the electric wire W is placed. The receiving portion main body 61 also has an opening OP through which the electric wire W can pass.

[0074] The opening / closing member 64 can open and close the opening OP. In the example shown in FIG. 15, the opening / closing member 64 has a second operating part 64c for operating the opening / closing member 64 to open and close it. When the opening / closing member 64 is in the open position (see the opening / closing member 64 indicated by the broken line in FIG. 15), the electric wire W can be inserted into the space SP2 through the opening OP. Furthermore, when the opening / closing member 64 is in the open position, the electric wire W can be removed from the space SP2 through the opening OP. When the opening / closing member 64 is in the closed position (see the opening / closing member 64 indicated by the solid line in FIG. 15), the electric wire W is surrounded by the receiving part main body 61 and the opening / closing member 64. Therefore, the electric wire W will not fall out of the electric wire receiving part 6.

[0075] When fixture 1A has an electric wire receiving portion 6, fixing fixture 1A to object B positions an electric wire W placed in electric wire receiving portion 6 within a predetermined range. On the other hand, by releasing fixing fixture 1A to object B and then rotating fixture 1A relative to object B (see arrow AR2), the relative position of electric wire W with respect to object B can be changed. Note that object B is, for example, an extendable rod member.

[0076] (Second embodiment) A fastener 1B according to the second embodiment will be described with reference to Figures 16 to 20. Figure 16 is a schematic perspective view showing fastener 1B according to the second embodiment. Figures 17 and 18 are schematic cross-sectional views showing fastener 1B according to the second embodiment. Figure 19 is a schematic perspective view showing an example of lever 3. Figure 20 is a schematic perspective view showing fastener 1B according to a first modified example of the second embodiment.

[0077] Fixing device 1B in the second embodiment differs from fixing device 1A in the first embodiment in that lever 3 cannot rotate around first axis AX1. In other respects, the second embodiment is similar to the first embodiment.

[0078] In the second embodiment, differences from the first embodiment will be mainly described, and a repetitive description of matters already described in the first embodiment will be omitted. Therefore, it goes without saying that matters already described in the first embodiment can be adopted in the second embodiment even if they are not explicitly described in the second embodiment.

[0079] As illustrated in FIG. 16, the fixing device 1B in the second embodiment includes: (1) a gripping member 2 having a first gripping portion 21 and a second gripping portion 22 and capable of gripping an object B; (2) a lever 3 capable of pulling the second gripping portion 22 in a first direction DR1 toward the first gripping portion 21; (3) a pressing member 4 that moves in a second direction DR2 different from the first direction DR1 to press the lever 3, and thereby moves the lever 3 in the first direction DR1; and (4) an operating member 5 having an operating portion 53 to move the pressing member 4 in the second direction DR2.

[0080] (operation) In the example shown in FIG. 17 , when the operating portion 53 is operated in a first operating direction MR1, the operating member 5 moves the pressing member 4 in a second direction DR2. When the pressing member 4 moves in the second direction DR2, the lever 3 moves in a first direction DR1 that is different from the second direction DR2. When the lever 3 moves in the first direction DR1, the lever 3 pulls the second gripping portion 22 in the first direction DR1, reducing the distance between the first gripping portion 21 and the second gripping portion 22. In this way, the object B placed between the first gripping portion 21 and the second gripping portion 22 is gripped by the first gripping portion 21 and the second gripping portion 22 (see FIG. 18 ).

[0081] 18, when the operating portion 53 is operated in the second operating direction MR2, (1) the force of the gripping member 2 returning to its original shape causes the second gripping portion 22 to move in the third direction DR3 (in other words, in the direction away from the first gripping portion 21), (2) the lever 3 to move in the third direction DR3, and (3) the pressing member 4 to move in the fourth direction DR4. In this way, the grip of the object B by the first gripping portion 21 and the second gripping portion 22 is released (see FIG. 17).

[0082] In the second embodiment, fastener 1B can be easily fixed to object B by utilizing the movement of pressing member 4 and lever 3. Furthermore, since the direction of movement of pressing member 4 (more specifically, second direction DR2) caused by operation of operating unit 53 differs from the direction of movement of lever 3 (more specifically, first direction DR1), there is a high degree of freedom in the arrangement of operating unit 53. For example, operating unit 53 does not need to be arranged on an extension of the longitudinal direction of lever 3. In the example shown in FIG. 17 , operating unit 53 is rotatable around operating axis AX, and the extension direction of operating axis AX is perpendicular to first direction DR1. Furthermore, in the example shown in FIG. 18 , operating unit 53 is arranged on the opposite side of plane PL passing through lever 3 from space SP1 in which object B to be gripped by gripping member 2 is arranged. It goes without saying that, in the second embodiment, the arrangement of operating unit 53 in fastener 1B is not limited to the examples shown in FIGS. 17 and 18 .

[0083] (First engagement portion 32 and second engagement portion 23) In the example shown in FIG. 16, the lever 3 (more specifically, the tip portion 31 of the lever 3) has a first engagement portion 32 that engages with the second engagement portion 23 of the second grip portion 22. In the example shown in FIG. 19, the first engagement portion 32 is an engagement hole portion 32h. As exemplified in FIG. 19, the engagement hole portion 32h is preferably an elongated hole portion having a major axis in a direction along the longitudinal direction of the lever 3.

[0084] (Second engagement portion 23) 16, the second gripping portion 22 has a second engagement portion 23 that engages with the first engagement portion 32 of the lever 3. When the first engagement portion 32 is an engagement hole 32h, the second engagement portion 23 preferably has a shape that allows it to be inserted into the engagement hole 32h. The second engagement portion 23 may be formed by an elongated member 23c such as a screw member or a pin member. Alternatively, the second engagement portion 23 may be formed by cutting a portion of the second gripping portion 22.

[0085] Alternatively, one of the first engaging portion 32 and the second engaging portion 23 may be an engaging recess, and the other of the first engaging portion 32 and the second engaging portion 23 may be an engaging protrusion. The first engaging portion 32 and the second engaging portion 23 may have any shape as long as they can engage with each other.

[0086] (Wire receiving part 6) 20, the fixture 1B includes a wire receiving portion 6 that can receive the wire W. The wire receiving portion 6 has a receiving portion main body 61 and an opening / closing member 64.

[0087] The receiving portion main body 61 defines a space SP2 in which the electric wire W is placed. The receiving portion main body 61 also has an opening OP through which the electric wire can pass.

[0088] The opening / closing member 64 can open and close the opening OP. In the example shown in FIG. 20 , the opening / closing member 64 has a second operating part 64c for operating the opening / closing member 64 to open and close. When the opening / closing member 64 is in the open position, the electric wire W can be inserted into the space SP2 through the opening OP. Furthermore, when the opening / closing member 64 is in the open position, the electric wire W can be removed from the space SP2 through the opening OP. When the opening / closing member 64 is in the closed position, the electric wire W is surrounded by the receiving part main body 61 and the opening / closing member 64. Therefore, the electric wire W will not fall out of the electric wire receiving part 6.

[0089] (Third embodiment) An electric wire cutting tool 100 according to the third embodiment will be described with reference to Fig. 21. Fig. 21 is a schematic front view showing the electric wire cutting tool 100 according to the third embodiment.

[0090] In the third embodiment, differences from the first and second embodiments will be mainly described, and a repetitive description of matters already described in the first or second embodiment will be omitted. Therefore, it goes without saying that matters already described in the first or second embodiment can be adopted in the third embodiment, even if they are not explicitly described in the third embodiment.

[0091] The wire cutting tool 100 in the third embodiment includes a fixture 1, a rod member 110, a first wire gripper 120, and a second wire gripper 130. In the third embodiment, the object B is the rod member 110.

[0092] As the fixing device 1 of the wire cutting tool 100 in the third embodiment, the fixing device 1A in the first embodiment may be adopted, the fixing device 1B in the second embodiment may be adopted, or another fixing device may be adopted.

[0093] Fixture 1 includes (1) gripping member 2 having first gripping portion 21 and second gripping portion 22 and gripping rod member 110, (2) lever 3 capable of pulling second gripping portion 22 in a first direction DR1 toward first gripping portion 21, (3) pressing member 4 that moves in a second direction DR2 different from first direction DR1 to press lever 3, thereby moving lever 3 in first direction DR1, (4) operating member 5 having operating portion 53 to move pressing member 4 in second direction DR2, and (5) electric wire receiving portion 6. (7) Electric wire receiving portion 6 defines space SP2 in which electric wire W is placed, and includes receiving portion main body 61 having opening OP, and opening / closing member 64 that can open and close opening OP.

[0094] The gripping member 2, lever 3, pressing member 4, operating member 5, and wire receiving portion 6 have already been described in the first or second embodiment, so a repeated description of these configurations will be omitted.

[0095] The rod member 110 is gripped by the gripping member 2. When the rod member 110 is gripped by the gripping member 2, the fixing device 1 is fixed to the rod member 110. By fixing the fixing device 1 to the rod member 110, the electric wire W to be placed in the electric wire receiving portion 6 is positioned within a predetermined range. On the other hand, when the gripping of the rod member 110 by the gripping member 2 is loosened, the fixing device 1 is rotatable around the longitudinal axis L1 of the rod member 110. By rotating the fixing device 1 around the longitudinal axis L1 of the rod member 110, the position of the electric wire placed in the electric wire receiving portion 6 is changed.

[0096] The rod member 110 is preferably extendable in the direction along the longitudinal axis L1. When the rod member 110 is extendable, the distance between the first wire gripper 120 and the second wire gripper 130 can be changed by extending or contracting the rod member 110.

[0097] The first wire gripper 120 is disposed at the first end 110a of the rod member 110. The first wire gripper 120 grips a first portion of the electric wire W.

[0098] The second wire gripper 130 is disposed at the second end 110b of the rod member 110. The second wire gripper 130 grips a second portion of the electric wire W.

[0099] When the rod member 110 is contracted in a direction along the longitudinal axis L1 of the rod member with the first wire gripper 120 gripping a first portion of the electric wire W and the second wire gripper 130 gripping a second portion of the electric wire W, the distance between the first wire gripper 120 and the second wire gripper 130 is reduced. As a result, the portion of the electric wire W located between the first wire gripper 120 and the second wire gripper 130 is loosened.

[0100] The rod member 110 includes an outer member 111, an inner member 112, and an operating unit 113. The operating unit 113 is a part for operating the relative movement of the inner member 112 with respect to the outer member 111. The operating unit 113 is connected to the rod member 110, and is rotatable around the second axis AX2. The operating unit 113 has an engaging portion 113c that engages with the distal end of the remote control member.

[0101] An example of a mechanism for contracting the extendable rod member 110 using a remote control will be described. As an example, assume that (A) the operating unit 113 is provided with a first bevel gear that rotates together with the operating unit about the second axis AX2, (B) the outer member 111 is provided with a second bevel gear connected to the first bevel gear so as to be able to transmit a load, (C) the second bevel gear rotates together with a threaded rod having an external thread disposed on its outer periphery about the longitudinal axis L1 of the rod member 110, and (D) the inner member 112 is screwed onto the threaded rod. In this case, when the operating unit 113 is rotated about the second axis AX2 by the remote control, the first bevel gear rotates about the second axis AX2, and the second bevel gear rotates about the longitudinal axis L1 of the rod member 110. When the second bevel gear rotates about the longitudinal axis L1, the threaded rod rotates about the longitudinal axis L1. When the threaded rod rotates around the longitudinal axis L1, the inner member 112 that is threadedly engaged with the threaded rod moves in a direction in which it is drawn into the outer member 111. In this way, the rod member 110 contracts.

[0102] In the third embodiment, the mechanism for contracting the rod member 110 is not limited to the mechanism described above.

[0103] By contracting the rod member 110, the electric wire W (a portion of the electric wire W) located between the first wire gripper 120 and the second wire gripper 130 is loosened, and then the electric wire cutting operation and the electric wire sorting operation are performed. First, the loosened portion of the electric wire W is cut by a cutting tool. As a result, a first cut end and a second cut end are formed on the electric wire W. Next, the first cut end and the second cut end are sorted (for example, sorted in the vertical direction). The electric wire cutting operation is completed by the above steps (more specifically, a step of contracting the rod member 110 while the first wire gripper 120 grips the first portion of the electric wire W and the second wire gripper 130 grips the second portion of the electric wire W, a step of cutting the loosened portion of the electric wire W formed by the contraction of the rod member 110 with a cutting tool, and a step of sorting the first cut end and the second cut end formed by the cutting).

[0104] In order to efficiently separate the first cut end portion and the second cut end portion, the wire cutting tool 100 includes the fixture 1 having the wire receiving portion 6.

[0105] The wire receiving portion 6 receives the wire W in the region between the first wire gripper 120 and the second wire gripper 130 and positions the wire W within a predetermined range.

[0106] When dividing the first cut end and the second cut end of the electric wire, for example, the electric wire connected to the first cut end is placed in the space SP2 defined by the electric wire receiving portion 6, and then the fixing device 1 is rotated around the longitudinal axis L1 of the rod member 110.

[0107] The wire cutting tool 100 in the third embodiment may include a second fastener 1′ in addition to the fastener 1. As the second fastener 1′, the fastener 1A in the first embodiment may be adopted, the fastener 1B in the second embodiment may be adopted, or another fastener may be adopted.

[0108] (Fixing method) Next, a fixing method in the embodiment will be described with reference to Figures 1 to 22. Figure 22 is a flowchart showing an example of the fixing method in the embodiment.

[0109] Fixing device 1 used in the fixing method of the embodiment may be fixing device 1A of the first embodiment, fixing device 1B of the second embodiment, or another fixing device.

[0110] Fixture 1 includes (1) gripping member 2 having first gripping portion 21 and second gripping portion 22, (2) lever 3, (3) pressing member 4 capable of pressing lever 3, and (5) operating member 5 having operating portion 53. Grip member 2, lever 3, pressing member 4, and operating member 5 have already been described in the first, second, or third embodiment, so repeated description of these configurations will be omitted.

[0111] In a first step ST1, a fastener 1 is prepared, with an object B disposed between first gripping portion 21 and second gripping portion 22. First step ST1 is a preparation process. Object B disposed between first gripping portion 21 and second gripping portion 22 may be a rod member (for example, rod member 110 with first wire gripper 120 disposed at first end 110a and second wire gripper 130 disposed at second end 110b), or may be a member of another shape.

[0112] In first step ST1, fixture 1 may be prepared with object B already placed between first gripping portion 21 and second gripping portion 22. In the example shown in Fig. 16, fixture 1B is prepared with object B already placed between first gripping portion 21 and second gripping portion 22, and with first engagement portion 32 of lever 3 and second engagement portion 23 of second gripping portion 22 engaged.

[0113] Alternatively, in first step ST1, fixture 1 and object B may be prepared separately, and then object B may be placed between first gripping portion 21 and second gripping portion 22. In the example shown in FIG. 3(a), fixture 1A is prepared without object B being placed between first gripping portion 21 and second gripping portion 22, and then object B is placed between first gripping portion 21 and second gripping portion 22, and then first engagement portion 32 of lever 3 and second engagement portion 23 of second gripping portion 22 are engaged (see FIG. 3(b)).

[0114] In the example shown in FIG. 3(a), the engagement between the first engagement portion 32 and the second engagement portion 23 is performed by operating the operating portion 53 in a first operating direction MR1. More specifically, by operating the operating portion 53 in the first operating direction MR1 about the operating axis AX, the lever 3 rotates in a first rotational direction R1 about the first axis AX1. By rotating the lever 3 in the first rotational direction R1, the lever 3 moves from a first position P1 (see FIG. 3(a)), where the engagement between the first engagement portion 32 and the second engagement portion 23 is released, to a second position P2 (see FIG. 3(b)), where the first engagement portion 32 and the second engagement portion 23 are engaged with each other.

[0115] In the second step ST2, the operating portion 53 is operated to move the pressing member 4 in the second direction DR2. The second step ST2 is a pressing member moving step. In the pressing member moving step, the operating portion 53 is operated in the first operating direction MR1.

[0116] 1 or 17, when the operating unit 53 is operated in the first operating direction MR1 about the operating axis AX, the pressing member 4 moves in the second direction DR2. More specifically, when the operating unit 53 is operated in the first operating direction MR1 about the operating axis AX, the operating member 5 moves in the second direction DR2, and the operating member 5 presses the pressing member 4 in the second direction DR2. As a result, the pressing member 4 moves in the second direction DR2.

[0117] 3(a), the operation direction of the operating unit 53 when rotating the lever 3 around the first axis AX1 is the first operation direction MR1, and in FIG. 1, the operation direction of the operating unit 53 when moving the pressing member 4 in the second direction DR2 is the first operation direction MR1. Therefore, by operating the operating unit 53 in the first operation direction MR1, the operation of rotating the lever 3 around the first axis AX1 and the operation of moving the pressing member 4 in the second direction DR2 are executed simultaneously or successively.

[0118] In the third step ST3, the movement of the pressing member 4 in the second direction DR2 is converted into the movement of the lever 3 in the first direction DR1 which is different from the second direction DR2. The third step ST3 is a conversion step.

[0119] In the example shown in FIG. 1 or 17, when the pressing member 4 moves in the second direction DR2, the pressing member 4 presses the pressed portion 35 of the lever 3 (more specifically, the pressed portion 35 provided at the base end 34 of the lever 3). The pressing force with which the pressing member 4 presses the lever 3 has a force component in the second direction DR2 and a force component F1 in the first direction DR1. When the force component F1 in the first direction DR1 acts on the lever 3, the lever 3 moves in the first direction DR1. In the example shown in FIG. 7 or 18, the pressing member 4 has a first inclined surface 421 that presses the pressed portion 35. The first inclined surface 421 resolves the pressing force with which the pressing member 4 presses the lever 3 into a force component in the second direction DR2 and a force component in the first direction DR1. 7 or 18, the pressed portion 35 of the lever 3 has a second inclined surface 352 that is pressed by the pressing member 4. The second inclined surface 352 resolves the pressing force with which the pressing member 4 presses the lever 3 into a force component in the second direction DR2 and a force component in the first direction DR1.

[0120] In a fourth step ST4, the second gripping portion 22 is displaced toward the first gripping portion 21. The fourth step ST4 is a displacement step. In the displacement step, the lever 3 pulls the second gripping portion 22 in the first direction DR1, thereby displacing the second gripping portion 22 toward the first gripping portion 21.

[0121] 2 or 18, when the lever 3 moves in the first direction DR1, the first engagement portion 32 of the lever 3 pulls the second engagement portion 23 of the second gripping portion 22 in the first direction DR1. In this way, the second gripping portion 22 is displaced toward the first gripping portion 21. The displacement of the second gripping portion 22 in the direction toward the first gripping portion 21 may be achieved by elastic deformation of the gripping member 2, as illustrated in FIG. 2. Alternatively, the displacement of the second gripping portion 22 in the direction toward the first gripping portion 21 may be achieved by the second gripping portion 22 rotating about the axis of the hinge 29 relative to the first gripping portion 21, as illustrated in FIG. 14.

[0122] In fifth step ST5, object B is gripped by first gripping portion 21 and second gripping portion 22 displaced toward first gripping portion 21. In this way, fixing device 1 is fixed to object B.

[0123] The fixing method in the embodiment makes it possible to easily fix fixing device 1 to object B. More specifically, fixing device 1 can be easily fixed to object B by operating operation unit 53 in first operation direction MR1.

[0124] The fixing method in the embodiment may include a second fixing step (sixth step ST6) of fixing fixing device 1 to object B. The second fixing step includes a gripping release step (substep ST6-1) of releasing the grip of object B by first gripping unit 21 and second gripping unit 22, an attitude change step (substep ST6-2) of changing the attitude of fixing device 1 with respect to object B, and a second object gripping step (substep ST6-3) of gripping object B by first gripping unit 21 and second gripping unit 22 displaced toward first gripping unit 21.

[0125] The grip releasing step (in other words, substep ST6-1) is executed by operating the operating unit 53. In the example shown in Fig. 2 or 18, in the grip releasing step, the operating unit 53 is operated in the second operating direction MR2 (more specifically, the direction opposite to the first operating direction MR1).

[0126] When the operating unit 53 is operated in the second operating direction MR2, the pressing member 4 becomes movable in the fourth direction DR4 (more specifically, the direction opposite to the second direction DR2), and the lever 3 becomes movable in the third direction DR3 (more specifically, the direction opposite to the first direction DR1). As a result, the second gripping unit 22 is displaced in a direction away from the first gripping unit 21, and the grip of the object B by the first gripping unit 21 and the second gripping unit 22 is released. In this specification, "releasing the grip" means making it possible to change the attitude of the fixing device 1 with respect to the object B. Therefore, in the "releasing the grip" state, it is acceptable for some gripping force to be applied to the object B from the gripping member 2.

[0127] Fixing device 1 may have a first biasing member 81 that biases pressing member 4 in fourth direction DR4. In this case, when operating portion 53 is operated in second operating direction MR2, the biasing force of first biasing member 81 moves pressing member 4 in fourth direction DR4.

[0128] The attitude changing step (in other words, substep ST6-2) is performed by moving the fixing device 1 relative to the object B (for example, by rotating the fixing device 1 relative to the object B). In the example shown in FIG. 21, the attitude changing step includes rotating the fixing device 1 relative to the object B (more specifically, the rod member 110) about the longitudinal axis L1 of the object B. In the example shown in FIG. 21, by performing the attitude changing step, the first cut end portions of the electric wires positioned within a predetermined range by the fixing device 1 are separated from the second cut end portions of the electric wires positioned within a predetermined range by the second fixing device 1'.

[0129] The reorientation step may include rotating the fixture 1 around the longitudinal axis L1 of the object B using a remote-controlled tool.

[0130] The second object grasping step (in other words, substep ST6-3) is executed by operating the operation unit 53. In the example shown in Fig. 1 or 17, in the second object grasping step, the operation unit 53 is operated in the first operation direction MR1.

[0131] In the example shown in FIG. 1 or 17 , when the operating unit 53 is operated in the first operating direction MR1 around the operating axis AX in the second object gripping step, the pressing member 4 moves in the second direction DR2. When the pressing member 4 moves in the second direction DR2, the pressing member 4 presses the pressed portion 35 of the lever 3. The pressing force with which the pressing member 4 presses the lever 3 has a force component in the second direction DR2 and a force component F1 in the first direction DR1. When the force component F1 in the first direction DR1 acts on the lever 3, the lever 3 moves in the first direction DR1. When the lever 3 moves in the first direction DR1, the first engagement portion 32 of the lever 3 pulls the second engagement portion 23 of the second gripping portion 22 in the first direction DR1. As a result, the second gripping portion 22 is displaced toward the first gripping portion 21. In this way, the object B is gripped again by the first gripping portion 21 and the second gripping portion 22 that has been displaced toward the first gripping portion 21.

[0132] The fixing method in this embodiment makes it easy to change the orientation of fixing device 1 relative to object B and to fix fixing device 1 to object B again. More specifically, by operating operation unit 53 in second operation direction MR2, it is possible to release the grip of object B by first gripping unit 21 and second gripping unit 22. Furthermore, after the orientation of fixing device 1 relative to object B has been changed, it is easy to fix fixing device 1 to object B again by operating operation unit 53 in first operation direction MR1.

[0133] Furthermore, the fixing method in the embodiment includes a conversion step of converting movement of the pressing member 4 in the second direction DR2 into movement of the lever 3 in the first direction DR1, which is different from the second direction DR2. Therefore, it is not necessary to arrange the operating unit 53 on an extension line of the longitudinal direction of the lever 3, and the degree of freedom in arranging the operating unit 53 in the fixing device 1 is great.

[0134] The present invention is not limited to the above-described embodiments or modifications, and it is clear that each embodiment or modification can be appropriately modified or changed within the scope of the technical concept of the present invention. Furthermore, any component used in each embodiment or modification can be combined with another embodiment or modification, and any component can be omitted from each embodiment or modification.
