Description

Technical Field

[0001] This utility model relates to a tool support device. Background Technology

[0002] A tool support device is known to support tools.

[0003] As a related technology, Patent Document 1 discloses an indirect live-line tool support device for a high-altitude work vehicle. The indirect live-line tool support device described in Patent Document 1 includes a base unit, a support arm member, and a holding device. The holding device includes: a first support member having a first holding portion; a second support member having a second holding portion; and a spacer member. In the indirect live-line tool support device described in Patent Document 1, when the diameter of the holding portion of the indirect live-line tool is a first diameter, the first and second holding portions hold the holding portion of the indirect live-line tool without passing through the spacer member. On the other hand, when the diameter of the holding portion of the indirect live-line tool is a second diameter smaller than the first diameter, the first and second holding portions hold the holding portion of the indirect live-line tool via the spacer member. Furthermore, the indirect live-line tool support device described in Patent Document 1 includes a braking device that brakes the swinging motion of the first and second support arms. When the brake lever is not activated, the braking device is locked, using friction to limit the relative rotation of the outer and inner rings, thus braking the swing of the second arm relative to the first arm. On the other hand, when the brake lever is activated, the braking device is unlocked, allowing the outer and inner rings to rotate relative to each other, thus allowing the second arm to swing relative to the first arm.

Figure 19 yes Figure 16 The DD arrow cross-section diagram.

[0106] like Figure 1 As illustrated, the tool support device 1A in the first embodiment includes a first arm member 2a and a second arm member 2b. The second arm member 2b is supported by the first arm member 2a and is rotatable. The first arm member 2a and the second arm member 2b may each be composed of a single part or a combination of multiple parts.

[0107] like Figure 2 As illustrated, the tool support device 1A in the first embodiment includes a first locking mechanism 3 and a first locking release member 4.

[0108] The first locking mechanism 3 locks the rotation of the second arm member 2b relative to the first arm member 2a by engaging with multiple engaging protrusions 32 and multiple second engaging parts 34. The first locking mechanism 3 is composed of multiple parts. In addition, in this specification, "locking" includes not only complete locking but also substantial locking. In other words, in the locked state, it allows the second arm member 2b to rotate slightly relative to the first arm member 2a due to the gap between the components.

[0109] like Figure 3 As illustrated, the first locking release member 4 releases the first locking mechanism 3 from locking the rotation of the second arm member 2b relative to the first arm member 2a. The first locking release member 4 may be composed of a single part or multiple parts.

[0110] like Figure 2 As illustrated, the first locking mechanism 3 has a pushing member 31, a pushed part 33, a plurality of engaging protrusions 32, a plurality of second engaging parts 34, and a first force-applying member 35.

[0111] like Figure 2 As illustrated, one of the first arm member 2a and the second arm member 2b is defined as the first member M1, and the other of the first arm member 2a and the second arm member 2b is defined as the second member M2.

[0112] The pushing member 31 pushes the pushed part 33, and the pushed part 33 is pushed by the pushing member 31 in the first direction DR1. Figure 2 and Figure 3 In the described example, the pushing member 31 is connected to the second member M2 in a manner that prevents relative rotation but allows linear relative movement. Furthermore, the pushed portion 33 is disposed on the first member M1. Additionally, in this specification, "prevents relative rotation" includes not only complete inability to rotate relative to each other, but also substantially inability to rotate relative to each other. In other words, relative rotation caused by gaps between members is not considered substantially relative rotation.

[0113] The following description uses an example where the first support arm member 2a is the first member M1 and the second support arm member 2b is the second member M2. In other words, the description focuses on an example where the pushing member 31 is connected to the second support arm member 2b in a manner that allows for linear relative movement with respect to the second support arm member 2b, and the pushed portion 33 is disposed in the first support arm member 2a. However, in a specific embodiment, the first support arm member 2a may be the second member M2 and the second support arm member 2b may be the first member M1. In other words, as... Figure 4As illustrated, the pushing member 31 is connected to the first support member 2a in such a way that it can move linearly relative to the first support member 2a, and the pushed part 33 may be disposed in the second support member 2b.

[0114] like Figure 2 As illustrated, a plurality of engaging protrusions 32 are disposed in one of the pushing member 31 and the pushed portion 33 (N1), and a plurality of second engaging portions 34 are disposed in the other of the pushing member 31 and the pushed portion 33 (N2).

[0115] exist Figure 3 In the described example, multiple engaging protrusions 32 are disposed on the pushed portion 33, and multiple second engaging portions 34 are disposed on the pushing member 31. However, in the embodiment, multiple engaging protrusions 32 may also be disposed on the pushing member 31, and multiple second engaging portions 34 may also be disposed on the pushed portion 33 (see, if necessary, the following). Figure 5 ).

[0116] like Figure 2 As illustrated, the first force-applying member 35 applies force to the pushing member 31 in a first direction DR1 toward the pushed portion 33. More specifically, the first force-applying member 35 applies force to the pushing member 31 in a first direction DR1 toward the pushed portion 33 to maintain the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging portions 34.

[0117] like Figure 3 As illustrated, the first locking release member 4 includes a first moving member 41, which resists the force applied by the first force-applying member 35, causing the pushing member 31 to move in a second direction DR2 opposite to the first direction DR1.

[0118] The tool support device 1A in the first embodiment includes a first locking mechanism 3, which comprises: a pushing member 31; a pushed portion 33; a plurality of engaging protrusions 32 disposed on one of the pushing member 31 and the pushed portion 33 (N1); a plurality of second engaging portions 34 disposed on the other of the pushing member 31 and the pushed portion 33 (N2); and a first force-applying member 35, which applies force to the pushing member 31 in a first direction DR1 toward the pushed portion 33. Accordingly, the angle of the second arm member 2b relative to the first arm member 2a can be effectively fixed by the engagement of the plurality of engaging protrusions 32 and the plurality of second engaging portions 34. More specifically, the aforementioned fixation can be effectively achieved by the pushing force of the pushing member 31 towards the first direction DR1 by the first force-applying member 35 and the engagement of the plurality of engaging protrusions 32 and the plurality of second engaging portions 34. Furthermore, since the force maintaining the fixation is distributed across multiple engaging protrusions 32, the load acting on each engaging protrusion 32 is smaller. Consequently, the durability of each engaging protrusion 32 is improved.

[0119] The tool support device 1A in the first embodiment includes a first locking release member 4, which includes a first moving member 41. The first moving member 41 moves the pushing member 31 in a second direction DR2, which is opposite to the first direction DR1. Accordingly, by using the first moving member 41 to move the pushing member 31 in the second direction DR2, the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging parts 34 can be released (see reference). Figure 3 By releasing this engagement, the angle of the second arm member 2b relative to the first arm member 2a can be adjusted. Furthermore, after this angle adjustment, by applying force through the first force-applying member 35, the plurality of engaging protrusions 32 and the plurality of second engaging portions 34 will return from the disengaged state to the engaged state. Accordingly, the angle of the second arm member 2b relative to the first arm member 2a can be easily fixed to the adjusted angle.

[0120] exist Figure 6 In the described example, the tool support device 1A has a first joint J1, which connects the first arm member 2a and the second arm member 2b to enable rotation. The first joint J1 is provided with the aforementioned plurality of engaging protrusions 32 (in... Figure 6 (not shown in the figure) and the aforementioned plurality of second engaging parts 34 (in Figure 6 (Not shown in the image).

[0121] Furthermore, in Figure 6 In the example described, tool support device 1A supports the holding tool 110a. Alternatively, tool support device 1A may also support tools other than the holding tool (e.g., cutting tools, rotating tools, peeling tools, compression tools, tools mounted on a remote control rod, etc.).

[0122] exist Figure 6 In the described example, the second arm member 2b supports the tool 110 via the second joint J2 and the third arm member 2c (more specifically, via the second joint J2 and the short arm, i.e., the third arm member 2c). Alternatively, the third arm member 2c can be omitted, and the tool 110 can be mounted directly on the second joint J2. As another alternative, the third arm member 2c and the second joint J2 can be omitted, and the tool 110 can be mounted directly on the second arm member 2b.

[0123] Next, refer to Figures 1 to 19 This describes any additional configuration that can be used in the tool support device 1A of the first embodiment (or the tool support device 1B of the second embodiment or the tool support device 1C of the third embodiment, which will be described later).

[0124] (First axis AX1)

[0125] exist Figure 2 In the described example, the first arm member 2a supports the second arm member 2b so that the second arm member 2b can rotate about a first axis AX1 parallel to the first direction DR1. Furthermore, the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging portions 34 supports at least a portion of the torque T acting from the second arm member 2b on the first arm member 2a about the first axis AX1.

[0126] exist Figure 2 In the described example, at least a portion of the torque T acting from the second arm member 2b on the first arm member 2a about the first axis AX1 is distributed and supported by the plurality of engaging protrusions 32. Accordingly, the load acting on each engaging protrusion 32 is smaller. As a result, the durability of each engaging protrusion 32 is improved. Furthermore, the frictional force generated between the plurality of engaging protrusions 32 and the plurality of second engaging parts 34 due to the torque T functions as a resistance force when the pushing member 31 moves in the second direction DR2. Accordingly, by applying force through the first force-applying member 35 and this resistance force, the pushing member 31 can be prevented from moving arbitrarily in the second direction DR2 (in other words, the lock release direction). This prevents lock release operations not based on the clear intention of the operator. In addition, the aforementioned resistance force is a frictional force that functions effectively as static friction before the pushing member 31 begins to move in the second direction DR2. Furthermore, once the pressing member 31 begins to move in the second direction DR2, the aforementioned resistance force changes from static friction to dynamic friction. Therefore, once the pressing member 31 begins to move in the second direction DR2, the aforementioned resistance force will not become excessive.

[0127] exist Figure 2 In the described example, a portion of the torque T acting from the second arm member 2b on the first arm member 2a about the first axis AX1 is supported by the frictional force between the surface 312 on the first direction DR1 side of the pushed member 31 and the surface 330 on the second direction DR2 side of the pushed portion 33. When a portion of the torque T is supported by the frictional force between the surface 312 on the first direction DR1 side of the pushed member 31 and the surface 330 on the second direction DR2 side of the pushed portion 33, the load acting on each engaging protrusion 32 will be smaller.

[0128] (Push-down component 31)

[0129] exist Figure 3 In the example described, the pressing member 31 has a pressing plate portion 311 and a first shaft 315.

[0130] The push plate portion 311 is the part that pushes the pushed portion 33. Figure 3In the example described, the push plate portion 311 extends along a surface perpendicular to the first axis AX1.

[0131] The first shaft 315 supports the push plate 311. Figure 3 In the described example, the pushing member 31 includes a first shaft 315, and the second member M2 (more specifically, the second support member 2b) includes a second shaft 215. The first shaft 315 and the second shaft 215 extend along the first axis AX1, respectively.

[0132] The first shaft 315 is connected to the second shaft 215, but cannot rotate relative to the second shaft 215 about the first axis AX1, but can move relative to it in a direction parallel to the first axis AX1.

[0133] Ideally, one of the first shaft 315 and the second shaft 215 has a hollow portion 316, which serves as a support for the other shaft 215. Figure 3 In the example described, the first shaft 315 has a hollow portion 316 that defines a receiving space SP for receiving the end 216 of the second shaft 215.

[0134] exist Figure 7 In the described example, in a cross-section perpendicular to the first axis AX1, the end 216 of the second shaft 215 has a non-circular shape (e.g., a hexagonal shape). Furthermore, in the cross-section perpendicular to the first axis AX1, the receiving space SP defined by the hollow portion 316 has a non-circular shape (e.g., a hexagonal shape) complementary to the aforementioned non-circular shape of the end 216 of the second shaft 215. These non-circular shapes prevent relative rotation of the first shaft 315 relative to the second shaft 215, while allowing linear movement of the first shaft 315 relative to the second shaft 215. Alternatively, polygonal shapes other than hexagonal shapes, keyhole shapes, oval shapes, or spline shapes can also be used as shapes that prevent relative rotation but allow linear movement.

[0135] exist Figure 2 In the described example, the pushing member 31 has a receiving member 317, which receives the force from the first locking release member 4 (more specifically, the first moving member 41). The receiving member 317 receives a force from the first locking release member 4 having a force component along the second direction DR2, thereby moving the pushing member 31, which includes the receiving member 317, in the second direction DR2 (see reference). Figure 3 As a result, the rotational lock of the first locking mechanism 3 on the second arm member 2b relative to the first arm member 2a will be released.

[0136] like Figure 2 and Figure 8 As illustrated, the receiving component 317 can be positioned at the first position P1 (refer to...) Figure 2 ) and the second position P2 (refer to) Figure 8 The receiving member 317 can be positioned between two positions. The first position P1 allows the movement of the first moving member 41 to be converted into the release of the rotary lock. The second position P2 prevents the movement of the first moving member 41 from being converted into the release of the rotary lock. When the receiving member 317 is in the second position P2, the rotary lock of the second arm member 2b relative to the first arm member 2a can be maintained regardless of the position of the first moving member 41. This prevents the rotary lock from being accidentally released.

[0137] The receiving member 317 can also be fixed to the first shaft 315 by screwing. In this case, by rotating the receiving member 317 about the first shaft 315, the position of the receiving member 317 can be changed between the first position P1 and the second position P2.

[0138] (Multiple locking protrusions 32)

[0139] like Figure 3 As illustrated, one of the pressing member 31 and the pressed portion 33 (N1) is provided with a plurality of engaging protrusions 32, including a first engaging protrusion 32-1 and a second engaging protrusion 32-2. The number of engaging protrusions 32 provided in one of the pressing member 31 and the pressed portion 33 (N1) can be 6 or more, 12 or more, 24 or more, or 36 or more. Accordingly, as the number of engaging protrusions 32 increases, the load acting on each engaging protrusion 32 will be reduced.

[0140] exist Figure 3 In the described example, the multiple engaging protrusions 32 include multiple engaging pins 321. For example... Figure 7 As illustrated, multiple card pins 321 can also be arranged at equal angular intervals around the first axis AX1.

[0141] As an alternative, in Figure 9 In the described examples, the multiple engaging protrusions 32 may also include multiple engaging convexities 323. For example... Figure 11 As illustrated, the multiple engaging protrusions 323 can also be arranged at equal angular intervals around the first axis AX1.

[0142] exist Figure 7 or Figure 11 In the described example, the multiple engaging protrusions 32 are regularly arranged around the first axis AX1. As an alternative, such as... Figure 12 As illustrated, the multiple engagement protrusions 32 may also be irregularly arranged around the first axis AX1.

[0143] (Multiple second card combinations 34)

[0144] exist Figure 3 In the described example, a plurality of second engaging portions 34 are provided in the other of the pressing member 31 and the pressed portion 33 (N2). The plurality of second engaging portions 34 can receive a plurality of engaging protrusions 32 including a first engaging protrusion 32-1 and a second engaging protrusion 32-2. The number of second engaging portions 34 may be 6 or more, 12 or more, 24 or more, or 36 or more.

[0145] The plurality of second engaging portions 34 may also include a plurality of engaging holes 341 that receive the plurality of engaging protrusions 32 (see reference). Figure 2 It may also include multiple engaging recesses 343 that receive multiple engaging protrusions 32 (see reference). Figure 9 In addition, the engaging recess can be an engaging groove, or a recess of a shape other than an engaging groove.

[0146] like Figure 7 or Figure 11 As illustrated, a plurality of second engaging portions 34 (more specifically, a plurality of engaging holes 341 or a plurality of engaging recesses 343) may also be arranged at equal angular intervals around the first axis AX1.

[0147] When multiple second engaging portions 34 are arranged at equal angular intervals around the first axis AX1, the angle of the second arm member 2b relative to the first arm member 2a can be adjusted using predetermined angular units. Figure 7 or Figure 11 In the described example, the plurality of second engaging portions 34 are arranged at equal angular intervals around the first axis AX1, covering an angular region of 360 degrees (in other words, covering an annular region). However, when the movable angle of the second arm member 2b can also be small, the plurality of second engaging portions 34 can also be arranged at equal angular intervals around the first axis AX1, covering an angular region smaller than 360 degrees (in other words, covering an arc-shaped region). Furthermore, due to the existence of gaps between the members, the operator can further fine-tune the angle of the second arm member 2b relative to the first arm member 2a, which has been adjusted using the aforementioned angular units.

[0148] like Figure 7 or Figure 11As illustrated, the plurality of second engaging portions 34 are ideally disposed in the outer peripheral region of the other (N2) of the pushing member 31 and the pushed portion 33. When the plurality of second engaging portions 34 are disposed in the outer peripheral region, the size of each second engaging portion 34 can be relatively increased, and the size of the engaging protrusion 32 received by each second engaging portion 34 can be relatively increased. Accordingly, the strength of each engaging protrusion 32 is improved.

[0149] exist Figure 3 In the described example, the plurality of second engaging portions 34 include a plurality of engaging holes 341 that can engage with a plurality of engaging protrusions 32. Each engaging hole 341 extends in a direction parallel to the first axis AX1. Figure 3 In the examples described, each engaging hole 341 is a bottomless through hole. Alternatively, each engaging hole 341 may also be a bottomed hole.

[0150] As an alternative, in Figure 10 In the described example, the plurality of second engaging portions 34 include a plurality of engaging recesses 343 (more specifically, a plurality of engaging grooves 344) that can engage with a plurality of engaging protrusions 32 (more specifically, a plurality of engaging convexities 323).

[0151] exist Figure 11 In the described example, the multiple engaging grooves 344 are grooves extending in a direction perpendicular to the first axis AX1 (more specifically, a radial direction perpendicular to the first axis AX1). Figure 10 In the described example, multiple engagement grooves 344 are formed on the surface 312 of the pressing member 31 in the first direction DR1, and multiple engagement protrusions 32 are disposed on the pressed portion 33. Alternatively, multiple engagement grooves 344 may be formed on the surface 330 of the pressed portion 33 in the second direction DR2, and multiple engagement protrusions 32 may be disposed on the pressing member 31.

[0152] As another alternative, such as Figure 13 As illustrated, a plurality of second engaging portions 34 (more specifically, a plurality of engaging recesses 343) may also be formed on the outer peripheral surface N2s of the other (N2) of the pushing member 31 and the pushed portion 33. Figure 13 In the described example, the plurality of second engaging portions 34 are plurality of engaging grooves 344 formed on the outer peripheral surface 313 of the pushing member 31. Figure 13 In the example described, multiple engagement grooves 344 extend in a direction parallel to the first axis AX1.

[0153] Furthermore, in Figure 13 In the example described, it is disposed in the pushed part 33 (in Figure 13The plurality of engaging protrusions 32 (more specifically, the plurality of engaging pins 321) (not shown in the figure) engage with the plurality of engaging grooves 344.

[0154] When the engagement groove 344 is formed on the outer peripheral surface 313, the size of the engagement groove 344 can be relatively increased, and the engagement pin 321 received by the engagement groove 344 can be relatively thickened. Accordingly, the strength of each engagement pin 321 will be improved.

[0155] like Figure 2 , Figure 9 , Figure 13 As illustrated, when multiple engaging holes 341 or multiple engaging recesses 343 have received multiple engaging protrusions 32, the rotation of the second arm member 2b relative to the first arm member 2a is locked. On the other hand, as... Figure 3 , Figure 10 As illustrated, when the multiple engaging protrusions 32 have disengaged from the multiple engaging holes 341 or the multiple engaging recesses 343, the rotation of the second arm member 2b relative to the first arm member 2a will be released.

[0156] exist Figure 7 , Figure 11 In the described example, the number of engaging protrusions 32 is the same as the number of second engaging portions 34 (more specifically, there are 36 engaging protrusions 32 and 36 second engaging portions 34). Alternatively, the number of engaging protrusions 32 and the number of second engaging portions 34 may differ. More specifically, the number of engaging protrusions 32 may be less than the number of second engaging portions 34. In this case, when multiple engaging protrusions 32 are engaged with multiple second engaging portions 34, at least one second engaging portion 34 will be in a free state, not engaged with any of the engaging protrusions 32.

[0157] (First friction plate 16)

[0158] like Figure 14 As illustrated, the tool support device 1A may also have a first friction plate 16. Figure 14 and Figure 15 In the described example, the first friction plate 16 is connected to the first member M1, and relative to the first member M1 (in Figure 14 In the described example, the first component M1 (e.g., the first arm component 2a) cannot rotate relative to the first support arm component 2a, but can move relative to the first support arm component 2a in a straight line. Ideally, the first component M1 (e.g., the first arm component 2a) has a first guide portion 26, which guides the first friction plate 16 to move in a direction parallel to the first axis AX1.

[0159] exist Figure 14In the described example, the first force-applying member 35 pushes the pressing member 31 in the first direction DR1 via the first friction plate 16. As a result, a plurality of engaging protrusions 32 disposed in one of the pressing member 31 and the pressed portion 33 (N1), and a plurality of second engaging portions 34 disposed in the other of the pressing member 31 and the pressed portion 33 (N2) engage with each other. In this way, the rotation of the second arm member 2b relative to the first arm member 2a is locked.

[0160] exist Figure 14 In the state shown, imagine a scenario where the first moving member 41 causes the pushing member 31 to move in the second direction DR2. In this case, as... Figure 15 As illustrated, the pushing member 31 and the first friction plate 16 will move in the second direction DR2 against the force applied by the first force-applying member 35. As a result, the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging parts 34 will be released, and the rotational lock of the second arm member 2b relative to the first arm member 2a will be released. In addition, in Figure 15 In the described example, the pressing member 31 (more specifically, the pressing plate portion 311) and the first friction plate 16 are brought into strong contact by the force applied by the first force-applying member 35. Therefore, it is possible to prevent the first friction plate 16 from rotating relative to the pressing member 31 at a high speed around the first axis AX1.

[0161] When the tool support device 1A has a first friction plate 16 that cannot rotate relative to the first member M1 but can move linearly relative to it, the second arm member 2b can be prevented from rotating at a high speed relative to the first arm member 2a when the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging parts 34 is disengaged. In other words, the first friction plate 16 provides strong resistance to the relative rotation of the second arm member 2b relative to the first arm member 2a. For example, in Figure 15 In the described example, the friction between the first friction plate 16 and the push plate portion 311 provides strong resistance to the relative rotation of the second arm member 2b relative to the first arm member 2a. Alternatively, this resistance can be configured such that no force is generated causing the relative rotation of the second arm member 2b relative to the first arm member 2a unless the operator applies force to it. Or, this resistance can be configured such that even when the operator does not apply force to the second arm member 2b, a low-speed relative rotational force is generated between the second arm member 2b and the first arm member 2a.

[0162] As described above, when the tool support device 1A has the first friction plate 16, it can prevent the second arm member 2b from rotating at a high speed relative to the first arm member 2a, thus ensuring the safety of the operator. For example, imagine a situation where the second arm member 2b of the tool support device 1A supports a heavy tool directly or via other components. In this case, even if the locking mechanism 3 is released when the operator's hand is removed from the second arm member 2b, the second arm member 2b will not rotate at a high speed. Accordingly, the safety of the operator can be ensured.

[0163] In addition, since the first friction plate 16 can receive the force from the first force-applying member 35 and move together with the pushing member 31 in a direction parallel to the first axis AX1, the presence of the first friction plate 16 will not hinder the operation of the first locking mechanism 3 and the first locking release member 4.

[0164] (Second friction plate 17)

[0165] exist Figure 16 In the example described, the tool support device 1A has a second friction plate 17 that contacts the first friction plate 16, in addition to the first friction plate 16.

[0166] The first friction plate 16 can rotate relative to the pushing member 31 about the first axis AX1, but cannot rotate relative to the pushed part 33 about the first axis. Furthermore, as... Figure 16 and Figure 17 As illustrated, the first friction plate 16 is movable relative to the pressed portion 33 in a direction parallel to the first axis AX1. More specifically, the first friction plate 16 is connected to the first member M1 (more specifically, the first support arm member 2a) and is movable relative to the pressed portion 33 in a direction parallel to the first axis AX1. Figure 18 As illustrated, the first component M1 (e.g., the first support arm component 2a) ideally has a first guide portion 26, which guides the movement of the first friction plate 16 in a direction parallel to the first axis AX1. Figure 18 In the described example, the first guide portion 26 has a spline shape in a cross-section perpendicular to the first axis AX1. Alternatively, the first guide portion 26 may also have a polygonal shape, an oval shape, or a keyhole shape in a cross-section perpendicular to the first axis AX1. In other words, the cross-sectional shape of the first guide portion 26 in a cross-section perpendicular to the first axis AX1 can be any shape as long as it prevents the first friction plate 16 from rotating around the first axis AX1 and allows the first friction plate 16 to move in a direction parallel to the first axis AX1.

[0167] exist Figure 16In the described example, the second friction plate 17 can rotate relative to the pressed portion 33 about the first axis AX1, but cannot rotate relative to the pressing member 31 about the first axis. Furthermore, as... Figure 16 and Figure 17 As illustrated, the second friction plate 17 is movable relative to the pressed portion 33 in a direction parallel to the first axis AX1. More specifically, the second friction plate 17 is connected to the pressing member 31 (more specifically, the first shaft 315 of the pressing member 31) and is movable relative to the pressed portion 33 in a direction parallel to the first axis AX1. Figure 19 As illustrated, the pushing member 31 (more specifically, the first shaft 315) ideally has a second guide 36, which allows the second friction plate 17 to move relative to the pushing member 31 in a direction parallel to the first axis AX1. Figure 19 In the described example, the second guide portion 36 has a spline shape in a cross-section perpendicular to the first axis AX1. Alternatively, the second guide portion 36 may also have a polygonal shape, an oval shape, or a keyhole shape in a cross-section perpendicular to the first axis AX1. In other words, the cross-sectional shape of the second guide portion 36 in a cross-section perpendicular to the first axis AX1 can be any shape as long as it prevents the second friction plate 17 from rotating around the first axis AX1 and allows the second friction plate 17 to move relative to the pushing member 31 in a direction parallel to the first axis AX1.

[0168] Furthermore, the second friction plate 17 only needs to be able to move slightly relative to the pushing member 31 in a direction parallel to the first axis AX1, so as to transmit the pushing force in the first direction DR1 from the second friction plate 17 to the first friction plate 16 (for example, in...). Figure 16 In the direction parallel to the first axis AX1, the length of the second guide section 36 can also be relatively short.

[0169] exist Figure 16 In the described example, the first force-applying member 35 pushes the pressing member 31 in the first direction DR1 via the first friction plate 16 and the second friction plate 17. As a result, a plurality of engaging protrusions 32 disposed in one of the pressing member 31 and the pressed portion 33 (N1), and a plurality of second engaging portions 34 disposed in the other of the pressing member 31 and the pressed portion 33 (N2) engage with each other. In this way, the rotation of the second arm member 2b relative to the first arm member 2a is locked.

[0170] exist Figure 16 In the state shown, imagine a scenario where the first moving member 41 causes the pushing member 31 to move in the second direction DR2. In this case, as... Figure 17As illustrated, the pushing member 31, the first friction plate 16, and the second friction plate 17 will move in the second direction DR2 against the force applied by the first force-applying member 35. As a result, the engagement between the plurality of engaging protrusions 32 and the plurality of second engaging parts 34 will be released, and the rotational lock of the second arm member 2b relative to the first arm member 2a will be released. Furthermore, in Figure 17 In the described example, the first friction plate 16 and the second friction plate 17 are brought into strong contact by the force applied by the first force-applying member 35. Therefore, it is possible to prevent the first friction plate 16 from rotating relative to the second friction plate 17 at a high speed around the first axis AX1. The first friction plate 16 cannot rotate relative to the pressed portion 33 around the first axis AX1, and the second friction plate 17 cannot rotate relative to the pressing member 31 around the first axis AX1. Accordingly, since the first friction plate 16 does not rotate relative to the second friction plate 17 at a high speed, it is possible to prevent the second arm member 2b from rotating relative to the first arm member 2a at a high speed.

[0171] As described above, when the tool support device 1A has a first friction plate 16 that cannot rotate relative to the pressed part 33 and a second friction plate 17 that cannot rotate relative to the pressing member 31, the engagement between the multiple engaging protrusions 32 and the multiple second engaging parts 34 is released, preventing the second arm member 2b from rotating at a high speed relative to the first arm member 2a. In other words, the frictional force acting between the first friction plate 16 and the second friction plate 17 provides strong resistance to the relative rotation of the second arm member 2b relative to the first arm member 2a. Furthermore, this resistance can be set such that no force is generated causing the relative rotation of the second arm member 2b relative to the first arm member 2a unless the operator applies force to the second arm member 2b. Alternatively, this resistance can be set such that even when the operator does not apply force to the second arm member 2b, a force is generated causing the second arm member 2b to rotate at a low speed relative to the first arm member 2a.

[0172] The first friction plate 16 can be one piece or multiple pieces. Similarly, the second friction plate 17 can be one piece or multiple pieces. Furthermore, the greater the number of first friction plates 16 and second friction plates 17, the greater the resistance. Figure 16 In the described example, the first friction plate 161 is clamped by the second friction plate 171 and the pushing member 31. Alternatively, the second friction plate 171 can also be clamped by the first friction plate 161 and other first friction plates 162. As another alternative, these other first friction plates 162 can also be clamped by the second friction plate 171 and other second friction plates 172.

[0173] exist Figure 16In the described example, there are three first friction plates 16. Alternatively, there may be one, two, or four or more first friction plates 16. Figure 16 In the example described, there are two second friction plates 17. Alternatively, there may be one or more second friction plates 17.

[0174] (First force-applying component 35)

[0175] exist Figure 16 In the examples described, the first force-applying member 35 applies force to the pushing member 31 in a first direction DR1 toward the pushed portion 33. The first force-applying member 35 is, for example, a spring member 351 (more specifically, a coil spring). Figure 16 In the examples described, the spring member 351 is configured to surround the pressing member 31 (more specifically, the first shaft 315 of the pressing member 31). More specifically, the spring member 351 is configured to be coaxial with the first shaft 315.

[0176] (First shell 37)

[0177] exist Figure 17 In the examples described, the first component M1 (more specifically, the first support arm component 2a) has a first housing 37, which houses the pushing plate portion 311 of the first force-applying component 35 and the pushing component 31. The first housing 37 may also house at least one first friction plate 16 and at least one second friction plate 17.

[0178] exist Figure 17 In the described example, the first housing 37 has an end plate 371. A through hole 372 may also be formed on the end plate 371 for a portion of the pushing member 31 (more specifically, the first shaft 315) to be inserted. Figure 17 In the example described, a portion of the first shaft 315 is disposed within the first housing 37, and another portion of the first shaft 315 is disposed outside the first housing 37.

[0179] exist Figure 15 or Figure 17 In the described example, at least one first friction plate 16 and / or at least one second friction plate 17 are disposed between the end plate 371 and the push plate portion 311 of the first housing 37. Figure 15 or Figure 17 In the example described, a first guide portion 26 for guiding the first friction plate 16 is formed on the side wall 373 (more specifically, the inner side of the side wall 373) of the first housing 37.

[0180] (Second force-applying component 45)

[0181] exist Figure 16 In the examples described, the tool support device 1A includes a second force-applying member 45 that applies force to the pressing member 31 in the second direction DR2. The second force applied by the second force-applying member 45 is smaller than the force applied by the first force-applying member 35. Accordingly, the pressing member 31, which receives the force applied in the first direction DR1 from the first force-applying member 35 and the second force applied in the second direction DR2 from the second force-applying member 45, presses the pressed part 33 in the default state.

[0182] exist Figure 16 In the examples described above, consider the scenario where the first moving member 41 causes the pushing member 31 to move in the second direction DR2. In this case, as... Figure 17 As illustrated, the pushing member 31 moves in the second direction DR2 against the force applied by the first force-applying member 35. The second force-applying member 45 assists the pushing member 31 in moving in the second direction DR2. This assistance helps to prevent the pushing member 31 from tilting relative to the first axis AX1 when it moves in the second direction DR2. Specifically, in Figure 16 In the examples described, due to the torque T acting from the second arm member 2b on the first arm member 2a about the first axis AX1, friction is generated between the side of the engaging protrusion 32 and the side of the second engaging part 34. Because of this friction, when the pushing member 31 moves in the second direction DR2, the pushing member 31 is more likely to tilt relative to the first axis AX1. The second force-applying member 45 assists in the movement of the pushing member 31 in the second direction DR2, thereby suppressing the tilting of the pushing member 31.

[0183] As described above, with the force of the first moving member 41 and the assistance of the second force-applying member 45, the pushing member 31 can move smoothly in the second direction DR2. Furthermore, as the pushing member 31 moves smoothly in the second direction DR2, the rotational lock of the second arm member 2b relative to the first arm member 2a is smoothly released.

[0184] The second force-applying member 45 is, for example, a spring member 451 (more specifically, a helical spring). Figure 16 In the examples described, a portion of the spring member 451 is disposed in the annular recess 46 formed in the first member M1 (more specifically the first support member 2a).

[0185] exist Figure 16 In the example described, the second force-applying member 45 is disposed between the bottom wall 461 of the annular recess 46 and the pushing member 31 (more specifically, the pushing plate portion 311).

[0186] (First Rope W1)

[0187] exist Figure 16In the examples described, the tool support device 1A has a first rope W1 that operates the first locking release member 4 (more specifically, the first moving member 41).

[0188] exist Figure 16 In the examples described, when the first rope W1 is pulled, increasing its tension, the first rope W1 operates the first moving member 41. The first moving member 41, operated by the first rope W1, moves the pushing member 31 in the second direction DR2. This releases the rotational lock of the second arm member 2b relative to the first arm member 2a. With this lock released, the operator can change the relative angle of the second arm member 2b to the first arm member 2a about the first axis AX1.

[0189] On the other hand, Figure 17 In the examples described, when the first rope W1 is slack, the pushing member 31 moves in the first direction DR1 due to the force applied by the first force-applying member 35. In this way, the rotation of the second arm member 2b relative to the first arm member 2a is locked again.

[0190] exist Figure 16 and Figure 17 In the described example, the tool support device 1A includes: a first moving member 41 that moves the pushing member 31 in a second direction DR2 against the force applied by the first force-applying member 35; and a first rope W1 that operates the first moving member 41. Accordingly, by pulling the first rope W1, the rotational locking of the second arm member 2b relative to the first arm member 2a can be released. Furthermore, by releasing the first rope W1, the rotation of the second arm member 2b relative to the first arm member 2a can be locked.

[0191] exist Figure 17 In the described example, the pushing member 31 has a receiving member 317, which receives the force from the first moving member 41. The receiving member 317 is capable of changing position between a first position P1 and a second position P2. The first position P1 is a position where the operation of the first rope W1 can be transmitted to the pushing member 31, and the second position P2 is a position where the operation of the first rope W1 cannot be transmitted to the pushing member 31. More specifically, when the receiving member 317 is in the first position P1, the first moving member 41 can transmit the traction force received from the first rope W1 to the receiving member 317 of the pushing member 31. On the other hand, when the receiving member 317 is in the second position P2, the first moving member 41 cannot transmit the traction force received from the first rope W1 to the receiving member 317 of the pushing member 31.

[0192] (First locking release component 4)

[0193] exist Figure 16 In the examples described, the first locking release member 4 includes: a first moving member 41, and a support member 43 that supports the first moving member 41 to be rotatable. Figure 16 In the example described, the support member 43 is mounted on the first member M1 (more specifically the first arm member 2a).

[0194] exist Figure 16 In the examples described, the first moving member 41 has: a first end 411 that is pulled by the first rope W1, and a second end 412 capable of pushing the pushing member 31 (more specifically, the receiving member 317 of the pushing member 31). Figure 16 In the described example, the first moving member 41 is a lever member having a fulcrum, a force point, and a point of application. More specifically, the fulcrum is formed by the portion that contacts the support member 43, the force point is formed by the first end 411 connected to the first rope W1, and the point of application is formed by the second end 412 of the pushing member 31.

[0195] exist Figure 16 In the examples described, when the first rope W1 is pulled, increasing its tension, the first rope W1 pulls the first end 411 of the first moving member 41. When the first end 411 is pulled, the first moving member 41 rotates around the portion in contact with the support member 43 as a fulcrum. The second end 412 of the first moving member 41, rotating around the fulcrum, pushes the pressing member 31 in the second direction DR2. As a result, the pressing member 31 moves in the second direction DR2, and the rotational lock of the second arm member 2b relative to the first arm member 2a is released.

[0196] exist Figure 16 In the examples described, the tension of the first rope W1 is used to operate the first moving member 41. Alternatively, hydraulic pressure can be used to operate the first moving member 41.

[0199] In the second embodiment, the description focuses on the points that differ from the first embodiment, and descriptions that are repeated in the first embodiment will be omitted. Accordingly, even if not explicitly described in the second embodiment, matters described in the first embodiment can still be used in the second embodiment.

[0200] like Figure 20 As illustrated, the tool support device 1B in the second embodiment includes (1) a first arm member 2a and (2) a second arm member 2b supported by the first arm member 2a and capable of rotation. Furthermore, as... Figure 21 As illustrated, the tool support device 1B in the second embodiment includes: (3) a first locking mechanism 3, which locks the rotation of the second arm member 2b relative to the first arm member 2a by engaging with a plurality of engaging protrusions 32 and a plurality of second engaging portions 34; and (4) a first locking release member 4, which releases the first locking mechanism 3 from locking the rotation of the second arm member 2b relative to the first arm member 2a, and, as Figure 21As illustrated, the first locking mechanism 3 includes: (5) a pushing member 31, which is connected to the second member M2 in a manner that can not rotate relative to the second member M2 but can move linearly relative to it when one of the first arm member 2a and the second arm member 2b is defined as the first member M1 and the other of the first arm member 2a and the second arm member 2b is defined as the second member M2; (6) a pushed portion 33, which is disposed on the first member M1 and is pushed by the pushing member 31; (7) a locking protrusion 32, which is disposed on one of the pushing member 31 and the pushed portion 33 (N1); (8) a second locking portion 34, which is disposed on the other of the pushing member 31 and the pushed portion 33 (N2); and (9) a first force-applying member 35, which applies force to the pushing member 31 in a first direction DR1 toward the pushed portion 33 to maintain the engagement between the plurality of locking protrusions 32 and the plurality of second locking portions 34. Furthermore, the first locking release member 4 includes (10) a first moving member 41, which resists the force applied by the first force-applying member 35 and causes the pushing member 31 to move in a second direction DR2 opposite to the first direction DR1.

[0201] Therefore, the second embodiment can achieve the same effect as the first embodiment.

[0202] Furthermore, in the second embodiment, as a configuration related to the first locking mechanism 3 and the first locking release member 4, (A) may also be adopted. Figure 2 , Figure 3 , Figure 7 ,and Figure 8 The recorded composition, (B) Figure 4 The recorded composition, (C) Figure 5 The recorded composition, (D) Figures 9 to 11 The recorded composition, (E) Figure 12 The recorded composition, (F) Figure 13 The recorded composition, (G) Figure 14 and Figure 15 The composition described herein, or (H) Figures 16 to 19 The composition recorded.

[0203] Next, refer to Figures 1 to 33 This explains any additional configuration that can be used in the tool support device 1B of the second embodiment.

[0204] (Base Unit 6)

[0205] exist Figure 22 In the example described, the tool support device 1B has a base unit 6 that can be directly installed on the cage 900 of the high-altitude work vehicle.

[0206] exist Figure 22In the described example, the base unit 6 has: an inner member 61 disposed inside the cage 900; an outer member 62 disposed outside the cage 900; and an upper member 63 disposed above the upper edge 904 of the cage 900. The inner member 61, the outer member 62, and the upper member 63 are interconnected to form an inverted U-shape when viewed from the side.

[0207] exist Figure 23 In the described example, when the base unit 6 is directly installed on the cage 900, the base unit 6 as a whole is configured to slide relative to the cage 900. In this case, compared to the case where a track member is installed on the cage 900 and the base unit of the tool support device is installed on the track member, the tool support device 1B can be made more compact overall. In other words, since the track member is omitted and the cage 900 itself functions as the track member, the tool support device 1B can be made more compact overall. Furthermore, since the base unit 6 is directly installed on the cage 900, the number of steps required to install the tool support device 1B on the cage 900 can be reduced.

[0208] This section describes in detail an example of a configuration that allows the base unit 6 to slide relative to the cage 900.

[0209] exist Figure 22 In the described example, the base unit 6 has: a first lateral movement member 610, a second lateral movement member 620, and a third lateral movement member 630. More specifically, the inner member 61 of the base unit 6 has the first lateral movement member 610, the outer member 62 of the base unit 6 has the second lateral movement member 620, and the upper member 63 of the base unit 6 has the third lateral movement member 630.

[0210] The first lateral moving member 610 is a member that can move in the lateral direction along the inner side 901 of the cage 900 while in contact with the inner side 901. Figure 22 In the described example, the first lateral movement member 610 includes at least one first roller 610r that rolls relative to the inner side 901 of the cage 900. Alternatively, or as an additional embodiment, the first lateral movement member 610 may also include at least one first slider that slides relative to the inner side 901 of the cage 900.

[0211] The second lateral movement member 620 is a member that can move in the lateral direction along the outer side 902 of the cage 900 while in contact with the outer side 902 of the cage 900. Figure 22In the described example, the second lateral movement member 620 includes at least one second roller 620r that rolls relative to the outer side 902 of the cage 900. Alternatively, or as an additional embodiment, the second lateral movement member 620 may also include at least one second slider that slides relative to the outer side 902 of the cage 900.

[0212] The third lateral moving member 630 is a member that can move in the lateral direction along the upper 903 of the cage 900 while in contact with the upper 903. Figure 22 In the described example, the third lateral movement member 630 includes at least one third roller 630r that rolls relative to the upper surface 903 of the cage 900. Alternatively, or as an additional embodiment, the third lateral movement member 630 may also include at least one third slider that slides relative to the upper surface 903 of the cage 900.

[0213] In addition to the second lateral moving member 620, the outer member 62 of the base unit 6 may also have an operating part 622, which causes the second lateral moving member 620 to move forward and backward relative to the outer side 902 of the cage 900. For example, by performing a first operation on the operating part 622, the second lateral moving member 620 can be pressed against the outer side 902 of the cage 900. Furthermore, by performing a second operation on the operating part 622, the second lateral moving member 620 can be retracted in a direction away from the outer side 902 of the cage 900.

[0214] exist Figure 22 In the described example, the base unit 6 has a hook member 624 that can hook onto the lower 904s of the upper edge 904 of the cage 900. When the hook member 624 is hooked onto the lower 904s of the upper edge 904 of the cage 900, it prevents the tool support device 1B from floating off the cage 900 (in other words, it prevents the third lateral movement member 630 from moving away from the upper 903 of the cage 900).

[0215] exist Figure 22 In the described example, the outer member 62 of the base unit 6 has a hook member 624. This outer member 62 may also have a hook member operating section 626, which moves the hook member 624 forward and backward relative to the upper edge 904 of the cage 900. For example, by performing a third operation on the hook member operating section 626, the hook member 624 can be pressed against the upper edge 904 of the cage 900. Furthermore, by performing a fourth operation on the hook member operating section 626, the hook member 624 can be retracted away from the upper edge 904 of the cage 900.

[0216] like Figure 24As illustrated, the base unit 6 may also include: a fixing member 66 (e.g., a fixing pad) for positioning and fixing the base unit 6 to the cage 900; and a fixing member operating part 67. The fixing member operating part 67 allows the fixing member 66 to move forward and backward relative to the cage 900 (more specifically, the inner side 901 of the cage 900). For example, by performing a fifth operation on the fixing member operating part 67, the fixing member 66 (e.g., the fixing pad) can be pressed against the cage 900. By pressing the cage 900 with the fixing member 66, the base unit 6 cannot move laterally, and the base unit 6 is fixed to the cage 900. For example, by performing a sixth operation on the fixing member operating part 67, the fixing member 66 (e.g., the fixing pad) can be retracted away from the cage 900.

[0217] exist Figure 24 In the example described, the inner member 61 of the base unit 6 has a fixing member 66 and a fixing member operation part 67.

[0218] (Third support arm component 2c, second locking mechanism 3f, second locking release component 4f)

[0219] exist Figure 20 In the described example, the tool support device 1B, in addition to the first arm member 2a and the second arm member 2b, also has a third arm member 2c. Furthermore, in Figure 25 and Figure 26 As illustrated, the tool support device 1B has a second locking mechanism 3f, a second locking release member 4f, and a second rope W2 for operating the second locking release member 4f.

[0220] The third arm member 2c is supported by the second arm member 2b and is able to rotate about the second axis AX2. The second axis AX2 is, for example, the same as the first axis AX1 (see reference). Figure 20 )parallel.

[0221] The second locking mechanism 3f locks the rotation of the third arm member 2c relative to the second arm member 2b. Furthermore, the second locking release member 4f releases the second locking mechanism 3f from locking the rotation of the third arm member 2c relative to the second arm member 2b.

[0222] The second locking mechanism 3f can be the same as the first locking mechanism 3 described in the first embodiment, and the second locking release member 4f can be the same as the first locking release member 4 described in the first embodiment. In this case, the description of the first locking mechanism 3 and the first locking release member 4 in the first embodiment can be regarded as the description of the second locking mechanism 3f and the second locking release member 4f in the second embodiment by making the following substitutions.

[0224] Furthermore, in the second embodiment, the components related to the second locking mechanism 3f and the second locking release member 4f can of course be replaced with... Figure 25 and Figure 26 The composition described herein adopts (A).

[0225] exist Figure 20 In the described example, the tool support device 1B has a second joint J2, which connects the second arm member 2b and the third arm member 2c to enable rotation. The second joint J2 is provided with the aforementioned plurality of third engaging protrusions 32f (in... Figure 20 (not shown in the figure) and the aforementioned multiple fourth engaging parts 34f (in Figure 20 (Not shown in the image).

[0226] (2d with structural components)

[0227] exist Figure 20 In the described example, the tool support device 1B has a connecting member 2d linked to the base unit 6. The connecting member 2d supports the first arm member 2a so that it can rotate about a third axis AX3. The third axis AX3 is, for example, parallel to the first axis AX1. Figure 20In the example described, the connecting member 2d is the link between the base unit 6 and the first support member 2a.

[0228] The structural component 2d can also be linked to the base element 6 in a manner that allows it to rotate around the fourth axis AX4. Figure 20 In the example described, the fourth axis AX4 is perpendicular to the third axis AX3. Furthermore, the fourth axis AX4 is a vertical axis. Figure 27 The diagram shows the situation where the aforementioned connecting member 2d and the portion V supported by the connecting member 2d can rotate relative to the base unit 6 about the fourth axis AX4.

[0229] (Third locking mechanism 3g, third locking release component 4g)

[0230] like Figure 28 and Figure 29 As illustrated, the tool support device 1B may also have a third locking mechanism 3g, a third locking release member 4g, and a third rope W3 for operating the third locking release member 4g.

[0231] The third locking mechanism 3g locks the rotation of the first support arm member 2a relative to the connecting member 2d. Furthermore, the third locking release member 4g releases the third locking mechanism 3g from locking the rotation of the first support arm member 2a relative to the connecting member 2d.

[0232] As the third locking mechanism 3g, the same mechanism as the first locking mechanism 3 described in the first embodiment may be used; and as the third locking release member 4g, the same member as the first locking release member 4 described in the first embodiment may be used. In this case, the description of the first locking mechanism 3 and the first locking release member 4 in the first embodiment can be regarded as the description of the third locking mechanism 3g and the third locking release member 4g in the second embodiment by making the following substitutions.

[0233] More specifically, in the above description of the first embodiment and the first locking mechanism 3 and the first locking release member 4, the following are referred to: "tool support device 1A", "first support arm member 2a", "second support arm member 2b", "first locking mechanism 3", "first locking release member 4", "first friction plates 16, 161, 162", "second friction plates 17, 171, 172", "first guide part 26", "push member 31", "engaging protrusion 32", "first engaging protrusion 32-1", "second engaging protrusion 32-2", "push part 33", "second engaging part 34", "first force application member 35", "second guide part 36", "first housing 37", and "first moving member 41".

[0234] Furthermore, in the second embodiment, the components related to the third locking mechanism 3g and the third locking release member 4g can of course be replaced with... Figure 28 and Figure 29 The composition described herein adopts (A). Figure 2 , Figure 3 , Figure 7 ,and Figure 8 The recorded composition, (B) Figure 4 The recorded composition, (C) Figure 5 The recorded composition, (D) Figures 9 to 11 The recorded composition, (E) Figure 12 The recorded composition, (F) Figure 13 The recorded composition, (G) Figures 16 to 19 The composition recorded.

[0235] exist Figure 20 In the described example, the tool support device 1B has a third joint J3, which connects the connecting member 2d to the first support member 2a so as to be rotatable. The third joint J3 is provided with the aforementioned plurality of fifth engaging protrusions 32g (in... Figure 20 (not shown in the diagram) and the aforementioned multiple sixth locking parts 34g (in Figure 20 (Not shown in the image).

[0236] In addition, although Figure 20 In the example described, the tool support device 1B has three joints (J1, J2, J3), but the tool support device 1B may of course have two or more joints.

[0237] (Foot pedal 7)

[0238] exist Figure 30 In the described example, the tool support device 1B has a foot pedal 7. Figure 31In the example described, the foot pedal 7 is connected to the first rope W1, the second rope W2, and the third rope W3 via the fourth rope W4.

[0239] exist Figure 31 In the example described, the configuration is such that by operating the foot pedal 7, the rotational lock of the second support arm member 2b relative to the first support arm member 2a is released, the rotational lock of the third support arm member 2c relative to the second support arm member 2b is released, and the rotational lock of the first support arm member 2a relative to the connecting member 2d is released in one operation.

[0240] More specifically, in Figure 31 In the described example, when the foot pedal 7 is operated (more specifically, when the foot pedal 7 is stepped on), the first rope W1 connected to the fourth rope W4 is pulled, increasing the tension of the first rope W1. When the tension of the first rope W1 increases, the first rope W1 operates the first moving member 41. Furthermore, the first moving member 41 operated by the first rope W1 moves the pushing member 31 in the second direction DR2 (see reference). Figure 15 (etc.). In this way, the rotational lock of the second arm member 2b relative to the first arm member 2a will be released. In addition, when the tool support device 1B is equipped with friction plates (16, 17), the release of this lock will not cause the second arm member 2b to rotate at a high speed around the first axis AX1.

[0241] exist Figure 31 In the described example, when the foot pedal 7 is operated (more specifically, when the foot pedal 7 is stepped on), the second rope W2 connected to the fourth rope W4 is pulled, increasing the tension of the second rope W2. When the tension of the second rope W2 increases, the second rope W2 operates the second locking release member 4f (more specifically, the second moving member 41f). Furthermore, the second locking release member 4f (more specifically, the second moving member 41f) operated by the second rope W2 moves the second pushing member 31f in the fourth direction DR4 (see reference). Figure 26 In this way, the rotational lock of the third arm member 2c relative to the second arm member 2b will be released. In addition, when the tool support device 1B is equipped with a friction plate such as the third friction plate 16f, the release of this lock will not cause the third arm member 2c to rotate at a high speed around the second axis AX2.

[0242] exist Figure 31In the described example, when the foot pedal 7 is operated (more specifically, when the foot pedal 7 is stepped on), the third rope W3 connected to the fourth rope W4 is pulled, increasing the tension of the third rope W3. When the tension of the third rope W3 increases, it operates the third locking release member 4g (more specifically, the third moving member 41g). Furthermore, the operation of the third locking release member 4g (more specifically, the third moving member 41g) by the third rope W3 causes the third pushing member 31g to move in the sixth direction DR6 (see reference). Figure 29 In this way, the rotational lock of the first arm member 2a relative to the connecting member 2d will be released. In addition, when the tool support device 1B is equipped with a friction plate such as the fifth friction plate 16g, the release of this lock will not cause the first arm member 2a to rotate at a high speed around the third axis AX3.

[0243] exist Figure 32 The following example illustrates a scenario where, with the first locking mechanism 3, the second locking mechanism 3f, and the third locking mechanism 3g unlocked, the angles of the first support arm member 2a relative to the connecting member 2d, the second support arm member 2b relative to the first support arm member 2a, and the third support arm member 2c relative to the second support arm member 2b are adjusted. These angle adjustments allow for adjustment of the position of the front end of the tool support device 1B.

[0244] When all three locks of the three locking mechanisms are released at once, the operator can efficiently adjust the position of the front end of the tool support device 1B. Furthermore, when the foot pedal 7 is used to release all three locks of the three locking mechanisms at once, the operator can efficiently and stably adjust the position of the front end of the tool support device 1B using both hands.

[0245] The foot pedal 7 can also be a toggle-type foot pedal. In this case, when the foot pedal 7 is pressed once, the locks of the three locking mechanisms will be released (in other words, the locks of the three joints (J1, J2, J3) will be released), and when the foot pedal 7 is pressed again, the locks of the three locking mechanisms will be activated (in other words, the locks of the three joints (J1, J2, J3) will be locked).

[0246] Alternatively, the foot pedal 7 can be replaced with a hand lever. In other words, it can also be configured such that, by operating the hand lever, the rotational lock of the second support arm member 2b relative to the first support arm member 2a, the rotational lock of the third support arm member 2c relative to the second support arm member 2b, and the rotational lock of the first support arm member 2a relative to the connecting member 2d can be released in one operation.

[0247] exist Figure 31In the described example, any of the receiving member 317, the second receiving member 317f, and the third receiving member 317g can also change its position from the forward position (P1, P3, P5) to the retracted position (P2, P4, P6). By changing the position of any of the receiving members (317, 317f, 317g) to the retracted position, joints that do not require angle adjustment can be fixed. In other words, by changing the position of the receiving members (317, 317f, 317g), it is possible to set joints that are unlocked by operating the foot pedal 7 or the lever, and joints that are unlocked without operating the foot pedal 7 or the lever.

[0248] As an alternative, a corresponding number of foot pedals 7 (or hand levers) can be prepared to match the number of locking mechanisms (3, 3f, 3g). Figure 33 In the described example, the first locking release member 4 (more specifically, the first moving member 41) is connected to the first foot pedal 7-1 via the first rope W1, the second locking release member 4f (more specifically, the second moving member 41f) is connected to the second foot pedal 7-2 via the second rope W2, and the third locking release member 4g (more specifically, the third moving member 41g) is connected to the third foot pedal 7-3 via the third rope W3. In this case, by operating each foot pedal (7-1, 7-2, 7-3), the locking mechanism (3, 3f, 3g) can be operated individually. Furthermore, it is preferable that each foot pedal be a toggle-type foot pedal.

[0249] In the second embodiment, an example is described where the locking release components (4, 4g, 4f) are operated by ropes. Alternatively, the locking release components (4, 4g, 4f) can also be operated hydraulically.

[0250] (Third Implementation)

[0251] Reference Figures 1 to 38 The tool support device 1C in the third embodiment is described below. Figure 34 This is a schematic side view of the tool support device 1C in the third embodiment. Figure 35 This diagram schematically shows the accessory AT being installed in the mounting section 8 of the tool support device 1C in a one-click manner. Figure 36 This is a schematic two-view drawing showing one example of accessory AT. Additionally, in Figure 36 A rough side view is recorded on the left side. Figure 36 The right side of the document contains a rough front view. Figure 37 This diagram shows that the AT accessory can be selectively installed on the first part Q1 and the second part Q2 of the remote operating tool 130m. Figure 38This diagram shows the situation where the engaging member 114 of the display accessory AT changes position between a forward position P7 that can engage with the mounting part 8 of the tool support device 1C and a retracted position P8 that cannot engage with the mounting part 8.

[0252] In the third embodiment, the description focuses on the points that differ from the first and second embodiments, and descriptions that are repeated in the first or second embodiments will be omitted. Accordingly, even if not explicitly described in the third embodiment, matters described in the first or second embodiments can still be used in the third embodiment.

[0253] like Figure 34 As illustrated, the tool support device 1C in the third embodiment includes: an accessory AT having a tool holding 110a; and a mounting part 8 for mounting the accessory AT. Additionally, the tool holding 110a can hold other tools 130.

[0254] like Figure 34 As illustrated, the tool support device 1C includes: (1) a first arm member 2a, (2) a second arm member 2b, (3) a first locking mechanism, and (4) a first locking release member. Since the "first arm member 2a", "second arm member 2b", "first locking mechanism", and "first locking release member" have been described in the first or second embodiment, repeated descriptions of these components are omitted.

[0255] like Figure 34 As illustrated, the mounting portion 8 of the tool support device 1C can also be configured on the third support arm member 2c. Alternatively, the mounting portion 8 of the tool support device 1C can also be configured on the second support arm member 2b, or on other members.

[0256] exist Figure 35 In the example described, the accessory AT with the holding tool 110a can be installed into the mounting section 8 in a one-click manner.

[0257] When the tool support device 1C has the aforementioned accessory AT, the operation of installing the holding tool 110a to the mounting part 8 of the tool support device 1C can be performed quickly and easily. For example, when the holding tool 110a is holding another tool 130, the holding tool 110a can be installed to the mounting part 8 of the tool support device 1C quickly and easily.

[0258] Next, refer to Figures 1 to 38 This explains any additional configuration that can be used in the tool support device 1C of the third embodiment.

[0259] (Accessories AT)

[0260] exist Figure 36 In the example described, accessory AT includes: a holding tool 110a, a base portion 113 configured for engaging with the engaging member 114 of the mounting portion 8, a force-applying member 116, and an operating member 117.

[0261] exist Figure 36 In the described example, the holding tool 110a has a first holding portion 111a, a second holding portion 112a, and a second operating member 115 that adjusts the distance between the first holding portion 111a and the second holding portion 112a. By operating the second operating member 115, the distance between the first holding portion 111a and the second holding portion 112a is reduced. In this way, other tools 130 disposed between the first holding portion 111a and the second holding portion 112a will be held by the first holding portion 111a and the second holding portion 112a.

[0262] exist Figure 36 In the described example, the holding tool 110a (more specifically, the first holding part 111a and the second holding part 112a) is able to hold the rod-shaped part 131 of the other tool 130 (e.g., the main rod 131a of the other tool 130). Figure 37 As illustrated, the holding tool 110a is ideally capable of selectively holding the first portion Q1 (e.g., the base end of the rod portion 131) of the rod portion 131 of other tools 130 and the second portion Q2 (e.g., the portion further forward than the base end of the rod portion 131) of the rod portion 131 of other tools 130.

[0263] like Figure 36 As illustrated, the second gripping part 112a of the gripping tool 110a may also be disposed on the base part 113 of the accessory AT. More specifically, the second gripping part 112a may also be integrally formed with the base part 113, or the second gripping part 112a may also be mounted on the base part 113.

[0264] exist Figure 38 In the described example, the engaging member 114 can change position between a forward position P7 where it can engage with the mounting portion 8 and a retracted position P8 where it cannot engage with the mounting portion 8. The engaging member 114 includes, for example, an engaging protrusion 114t. Furthermore, the mounting portion 8 includes, for example, an engaging recess 8t that can engage with the engaging protrusion 114t.

[0265] The force-applying member 116 applies force to the engaging member 114 in the direction from the retracted position P8 to the forward position P7. In this case, when no operating force is applied to the operating member 117, the force applied by the force-applying member 116 can maintain the position of the engaging member 114 in the forward position P7. The force-applying member 116 is, for example, a spring (more specifically, a coil spring or a torsion coil spring).

[0266] The operating member 117 resists the force applied by the force-applying member 116, causing the engaging member 114 to move from the forward position P7 to the retracted position P8. The operating member 117 includes, for example, an operating lever 117v.

[0267] exist Figure 35 In the described example, the accessory AT is configured such that pressing it against the mounting portion 8 automatically mounts the accessory AT to the mounting portion 8. More specifically, the configuration is such that pressing the accessory AT against the mounting portion 8 causes the engaging member 114 to temporarily move to a retracted position. Then, by applying force through the force-applying member 116, the engaging member 114 returns to the forward position. Through this action, the engaging member 114 of the accessory AT engages with the mounting portion 8 (more specifically, the engaging recess 8t) of the tool support device 1C, and the accessory AT is mounted to the mounting portion 8 of the tool support device 1C.

[0268] exist Figure 35 In the described example, when the accessory AT is already installed on the other tool 130, the accessory AT can be attached to or detached from the mounting portion 8 of the tool support device 1C. Therefore, the other tool 130 and the accessory AT can be considered as an integrated assembly. For example, when the accessory AT is installed on the other tool 130, the other tool 130 can be moved. Furthermore, the accessory AT, already installed on the other tool 130, can be installed onto the mounting portion of the tool support device 1C with a single click.

[0269] (Other tools 130)

[0270] exist Figure 37 In the described example, the other tool 130 held by the holding tool 110a of accessory AT is a remote operating tool 130m with a holding part or a cutting part at the front end. Furthermore, the remote operating tool 130m has a main rod 131a and a secondary rod 131b. The main rod 131a and the secondary rod 131b may also be electrically insulating operating rods.

[0271] exist Figure 36 In the described example, the accessory AT is configured such that its second gripping part 112a can be inserted between the main rod 131a and the auxiliary rod 131b of the remote operating tool 130m. More specifically, the accessory AT has an auxiliary rod escape space SQ defined by the second gripping part 112a and the base portion 113. Furthermore, the auxiliary rod escape space SQ and the second gripping part 112a are configured to be aligned in a straight line with the first gripping part 111a. Due to the presence of the auxiliary rod escape space SQ, when the main rod 131a is held by the gripping tool 110a, the movement of the auxiliary rod 131b (in other words, the operation of the auxiliary rod 131b) is not hindered by the accessory AT.

[0272] Furthermore, in this embodiment, the other tools 130 held by the holding tool 110a of accessory AT may also be tools other than remotely operated tools. Additionally, items other than tools may also be held on the holding tool 110a of accessory AT.

[0273] This utility model is not limited to the above-described embodiments or modifications. Within the scope of the technical concept of this utility model, it should be clear that appropriate modifications or alterations can be made to the embodiments or modifications. Furthermore, any constituent elements used in the embodiments or modifications can be combined with other embodiments or modifications, and any constituent elements can be omitted in the embodiments or modifications.
