Description

  The present invention relates to an indirect ratchet wrench holding tool for holding the posture of a ratchet body, which is used by being attached to an indirect ratchet wrench.

  An indirect ratchet wrench that is attached to the tip of an indirect hot wire tool (hot stick) is used as a tool for tightening or loosening a bolt such as a pull-down connector (for example, Patent Document 1, Patent) Reference 2).

  FIG. 9 shows an external view of a conventional typical indirect ratchet wrench 101. The indirect ratchet wrench 101 includes a ratchet main body 111 and a joint body 121 that rotates the ratchet main body 111, and is connected to the indirect hot wire tool 161 via a twist lock adapter 151 connected to the joint body 121.

  The ratchet body 111 includes two sockets 112 and 113 having different caliber diameters corresponding to bolts having different bolt diameters, a switching lever 114 for switching the rotation direction of the sockets 112 and 113, and a ratchet mechanism (not shown). The ratchet mechanism has a ratchet wheel and a detent for stopping, and rotates the sockets 112 and 113 only in one direction. When the ratchet body 111 is rotated in the reverse direction, the ratchet mechanism is idled and the sockets 112 and 113 do not rotate.

  The joint body 121 includes an L-shaped first arm 131 and a T-shaped second arm 141. The first arm 131 has a vertical part 134 having a bearing 133 at the upper part and a horizontal part 138 including a horizontal shaft 137 arranged orthogonal to the vertical part 134, and the support shaft 115 of the ratchet body 111 slides on the bearing 133. Fits freely. The support shaft 115 and the bearing 133 constitute a first joint 123, and the ratchet body 111 inserted into the bearing 133 can change the direction on a horizontal plane.

  The second arm 141 includes a cylindrical bearing 143 arranged in the horizontal direction, and a plate-like connecting portion 145 arranged orthogonal to the bearing 143 below the bearing 143, and the horizontal axis of the first arm 131. 137 is slidably fitted into the bearing 143. The horizontal shaft 137 and the bearing 143 constitute the second joint 125, and the ratchet body 111 supported by the first arm 131 is rotatable on the vertical plane with the bearing 143 as a starting point. The connecting portion 145 includes a star seat portion and connects to the star seat portion 153 provided on the twist lock adapter 151.

  Tightening bolts using the indirect ratchet wrench 101 or removing the bolts can be achieved by inserting the sockets 112 and 113 into the heads of the bolts and connecting them indirectly through the twist lock adapter 151 so that the ratchet body 111 turns. This is done by operating the line tool 161.

  The conventional indirect ratchet wrench 101 easily falls from the standing state even if a slight impact is applied to the ratchet main body 111, and faces downward (see FIG. 10). Further, in the conventional indirect ratchet wrench 101, it is difficult to hold the ratchet body 111 in an inclined state with respect to the second arm 141, so that it is difficult to insert the sockets 112 and 113 into the bolts. This is because the torque acting on the second joint 125 when the ratchet body 111 is tilted with respect to the second arm 141 causes the frictional force (resistance force) between the horizontal shaft 137 and the bearing 143 constituting the second joint 125. ).

JP 2014-140907 A JP 2012-87839 A

  In response to the above problem, the frictional force of the second joint 125, more specifically, the frictional force of the sliding surface between the horizontal shaft 137 and the bearing 143 can be increased to prevent the ratchet body 111 from overturning, or the ratchet body. 111 can be held in an inclined state with respect to the second arm 141. However, in this method, the force required to turn the second arm 141 becomes large, and a great deal of labor is required for tightening or removing the bolt.

  The indirect ratchet wrench 101 to which the indirect ratchet wrench holder 1 (hereinafter referred to as the posture holder 1) of the first embodiment of the present invention is attached and used is an indirect ratchet conventionally used as shown in FIGS. A wrench 101.

  The posture holder 1 is attached to the indirect ratchet wrench 101 to hold the posture of the ratchet main body 111 before operating (operating) the indirect ratchet wrench 101. The posture of the substrate 11 and the ratchet main body 111 is changed. A posture regulating plate 21 to be regulated, a first fixture 31 and a second fixture 51 for attaching the posture holder 1 to the indirect ratchet wrench 101, and a support body 41 that supports the second fixture 51.

  The substrate 11 is a rectangular plate that supports the attitude regulating plate 21 and the support body 41, and has a length L (height) that connects the upper arm 135 of the first arm 131 of the indirect ratchet wrench 101 to the second arm 141. This is the same as the length of the portion 145 up to the middle portion. There is no problem if the length L of the substrate 11 is further increased, but the posture holder 1 becomes larger. The width W of the substrate 11 is important for the posture holder 1 and is set to a specific width. This will be described with reference to the posture regulating plate 21. The substrate 11 is formed of a synthetic resin plate having rigidity that does not easily deform.

  The posture regulating plate 21 regulates the posture of the ratchet main body 111 by limiting the turning range of the ratchet main body 111, and the first arm 131 that supports the ratchet main body 111 abuts on the posture regulating plate 21, thereby causing the ratchet main body 111 to move. Hold 111 posture. Here, the holding of the posture of the ratchet body 111 is the posture with respect to the second arm 141 before the indirect ratchet wrench 101 is operated, and the posture is not restricted after the indirect ratchet wrench 101 is operated. This point will be described in detail in the usage method.

  The attitude regulating plate 21 is composed of a pair of left and right attitude regulating plates 21, both of which are made of a rectangular synthetic resin plate. The attitude regulating plate 21 has a rigidity that does not easily deform. The left and right attitude regulating plates 21 are arranged orthogonally to the substrate 11 at both upper ends of the substrate 11. In the posture holder 1, the substrate 11 and the right and left posture regulating plates 21 are integrally formed so as to bend the synthetic resin plate into a U shape. Note that the substrate 11 and the left and right posture regulating plates 21 may be manufactured separately and then joined.

  The size of the posture regulating plate 21 is substantially the same as the height of the vertical portion 134 of the first arm 131, and the length is substantially the same as the outer diameter of the bearing 133 of the first arm 131. The posture restricting plate 21 needs to have a size such that the side portion of the first arm 131 contacts the posture restricting plate 21 when the ratchet main body 111 turns (rotates) up to 15 degrees to the left and right with respect to the vertical axis. (See FIG. 4).

  The spacing between the left and right posture regulating plates 21 is maximum when the ratchet body 111 pivots left and right around the second joint 125, as shown in FIG. It is set to be able to turn 15 °. The reason why the turning range of the ratchet main body 111 with respect to the second arm 141 is set to be capable of turning at a maximum of 15 ° to the left and right and a maximum of 30 ° in total is as follows.

  Since the hexagonal bolt has one angle of 60 °, if the hexagonal sockets 112 and 113 can be rotated 30 ° in either the left or right direction with respect to the head of the hexagonal bolt, the sockets 112 and 113 are fitted to the hexagonal bolt. Can be included. Even when the sockets 112 and 113 are 12-sided sockets, the sockets 112 and 113 can be fitted into the hexagonal bolts if the sockets 112 and 113 can be rotated by 30 ° in either the left or right direction with respect to the heads of the hexagonal bolts. it can.

  The substrate 11 and the posture regulating plate 21 are further enlarged, and the side portion of the ratchet body 111 is brought into contact with the posture regulating plate 21 instead of the side portion of the first arm 131, so that the ratchet body 111 is in contact with the second arm 141. You may be allowed to turn left and right by a maximum of 15 °. However, in this method, the posture holder 1 becomes large.

  The first fixing tool 31 is for attaching the posture holding tool 1 to the indirect ratchet wrench 101 and includes band members 32 and 35 attached to the lower portions of the left and right posture regulating plates 21. Band attachment portions 22 and 23 for attaching the band members 32 and 35 are provided below the posture regulating plate 21. The band attachment portions 22 and 23 are posture restriction plates so that when the posture holder 1 is attached to the indirect ratchet wrench 101, the band members 32 and 35 come into contact with the vertical portion 134 below the bearing 133 of the first arm 131. The lower part of 21 is partly cut away.

  The band member 32 is made of a band-shaped synthetic resin material, has a width slightly smaller than the height of the vertical portion 134 below the bearing 133 of the first arm 131, and has the same length as the width W of the substrate 11. The band member 32 has a base end portion 33 joined to the band attachment portion 22 so as to be rotatable. The band member 32 may be rotatably connected to the band attaching portion 22 via a hinge. A surface fastener 34 having a loop portion is bonded to the front surface of the band member 32. A hook-and-loop fastener 34 having a loop portion with which the band member 33 is locked is also bonded to the lower portion of the posture regulating plate 21.

  The band member 35 has the same material and width as the band member 32, but its length is longer than the width W of the substrate 11. The band member 33 has a base end portion 36 rotatably joined to the band attaching portion 23, and a bent portion 37 is provided at a position having the same length as the width W of the substrate 11 from the base end portion 36. The band member 35 is configured to be rotatable with a base end portion 36 and a bent portion 37 as starting points. The band member 35 may be connected to the band attaching portion 23 via a hinge, and the bent portion 37 may be configured by a hinge mechanism. A hook-and-loop fastener 38 having a hook portion is bonded to the back surface of the band member 35.

  In the first fixing tool 31, the areas of the hook-and-loop fasteners 34 and 38 connected to each other are set to be very large. This is because, after the first fixing tool 31 is attached to the indirect ratchet wrench 101, it is necessary to maintain the connected state without disconnecting even when the indirect ratchet wrench 101 is operated.

  The support body 41 supports the second fixture 51, and when the indirect ratchet wrench 101 to which the posture holder 1 is attached is operated, the second fixture 51 is pressed and connected to the second arm 141. It is a member for opening. The support 41 includes a pair of left and right rectangular synthetic resin support plates 42.

  The support plate 42 has rigidity that does not easily deform, and a base end portion 43 is rotatably connected to both ends of the lower portion of the substrate 11 via a hinge 45. The support plate 42 is rotatable in a range of about 60 to about 150 ° with respect to the substrate 11 in plan view.

  The hinge 45 includes a spring (not shown), and the spring biases the support plate 42 in a direction parallel to the substrate 11 in a plan view. For this reason, before attaching the posture holder 1 to the indirect ratchet wrench 101 (see FIG. 1), each support plate 42 is opened about 150 ° with respect to the substrate 11 in a plan view. This angle is not limited to 150 °, and when the posture holder 1 is attached to the indirect ratchet wrench 101 and the indirect ratchet wrench 101 is operated, the support plate 42 can be opened to a position that does not interfere with the operation. Good.

  The size of the support plate 42 is substantially the same as the height from the upper end 142 of the second arm 141 to the intermediate portion of the connecting portion 145, and the length is longer than the bearing 143 of the second arm 141. The length of the joint 125 is substantially the same. The support plate 42 needs to have a size such that at least a part of the second arm 141 contacts the support plate 42 when the indirect ratchet wrench 101 to which the posture holder 1 is attached is operated.

  Also, when the posture holder 1 is attached to the indirect ratchet wrench 101, the length of the support plate 42 is at least the first so that the second fixture 51 can be brought into contact with the outer side portion 146 of the connecting portion 145. It is necessary to have a length from the back portion 139 of one arm 131 to the outer side portion 146 of the connecting portion 145.

  The second fixture 51 is for attaching the posture holder 1 to the indirect ratchet wrench 101, and includes band members 52 and 53 attached to the lower portions of the left and right support plates 42. Band attachment portions 47 and 48 for attaching the band members 52 and 53 are provided below the support plate 42.

  The band attaching portions 47 and 48 are partially attached to the lower portion of the support plate 42 so that the band members 52 and 53 come into contact with the outer side portion 146 of the connecting portion 145 when the posture holder 1 is attached to the indirect ratchet wrench 101. Notches are provided. The length of the support plate 42 is set such that the band members 52 and 53 abut against the outer side portion 146 of the connecting portion 145 when the posture holder 1 is attached to the indirect ratchet wrench 101, and the notch is omitted. May be.

  The band member 52 is made of a band-shaped synthetic resin material, and its length is 0.6 to 0.7 times the width W of the substrate 11. The band member 52 has a proximal end joined to the band attaching portion 47 so as to be rotatable. The band member 52 may be rotatably connected to the band attaching portion 47 via a hinge. A surface fastener 54 having a loop portion is bonded to the front surface of the band member 52.

  The material, width, and length of the band member 53 are the same as those of the band member 52, and the band member 53 is configured to be rotatable from the base end as in the case of the band member 52. The band member 53 may be coupled to the band attaching portion 48 via a hinge. A hook-and-loop fastener 55 having a hook portion is bonded to the back surface of the front end portion of the band member 53.

  The second fixing tool 51 is supported by the second arm 141 when the indirect ratchet wrench 101 with the posture holder 1 attached is operated in the same manner as the indirect ratchet wrench 101 with the posture holder 1 not attached. By pressing the plate 42, the connecting force (adhesive force) of the hook-and-loop fasteners 54 and 55 is set so that the left and right band members 52 and 53 are separated.

  Next, the usage method and operation | movement of the attitude | position holder 1 are demonstrated.

  With respect to the indirect ratchet wrench 101 in which the ratchet main body 111 is erected in the vertical direction, the substrate 11 is directed to the back part 139 of the first arm 131, and the posture regulating plate 21 is covered with both sides of the bearing 133 of the first arm 131. The first fixture 31 is mounted on the vertical portion 134 below the bearing 133 of the first arm 131. Further, the support plate 42 is disposed so as to cover the second joint 125, and the second fixing tool 51 is fixed to the outer side portion 146 of the connecting portion 145. At this time, the substrate 11 is positioned at the center of the indirect ratchet wrench 101.

  The posture holding tool 1 is fixed by the first fixing tool 31 and the second fixing tool 51 so that the substrate 11 is in contact with the back portion 139 of the first arm 131 and further sandwiches the second joint 125 from above and below as described above. The posture holder 1 attached to the indirect ratchet wrench 101 is stable without wobbling.

  As with the conventional indirect ratchet wrench 101, the insulating operation rod 161 is attached to the indirect ratchet wrench 101 to which the posture holder 1 is attached via the twist lock adapter 151, and the socket 112 is fitted into the head of the hexagon bolt. At this time, if the angle between the hexagon bolt and the socket 112 does not match and it is difficult to fit, only the ratchet main body 111 is inclined by 15 ° with respect to the vertical direction (see FIG. 4).

  When only the ratchet body 111 is tilted by 15 ° with respect to the vertical direction, the ratchet body 111 and the first arm 131 are tilted integrally with the second joint 125 as a starting point. At this time, the first fixture 31 remains connected, and the first arm 131 slides relative to the first fixture 31 and tilts. For this reason, even if the ratchet body 111 is tilted, the positional relationship between the posture holder 1 and the second arm 141 does not change.

  In the indirect ratchet wrench 101 that does not include the posture holder 1, when only the ratchet body 111 is tilted, the torque applied to the second joint 125 exceeds the frictional force, so that the ratchet body 111 falls as shown in FIG. . On the other hand, in the indirect ratchet wrench 101 to which the posture holder 1 is attached, the posture of the ratchet main body 111 is maintained by the posture restriction plate 21, so that the ratchet main body 111 does not fall (see FIG. 4). For this reason, the socket 112 can be easily fitted into the head of the hexagon bolt.

  After the socket 112 is fitted into the head of the hexagonal bolt, the insulating operation rod 161 is operated so that the socket 112 rotates as in the conventional indirect ratchet wrench 101. When the insulation operation rod 161 is operated, as shown in FIG. 5, the second arm 141 turns and hits the support plate 42. When the operation is further continued from this state, the left and right band members 52 and 53 are separated and the second fixture 51 is cut. Is released.

  When the second fixture 51 is opened, the support plate 42 is greatly opened by the action of the spring provided in the hinge 45 as shown in FIG. Note that even if the insulation operating rod 161 is operated, no force is applied to the posture regulating plate 21, so the first fixture 31 remains connected, and the posture holder 1 continues to be connected via the first fixture 31. It remains attached to the indirect ratchet wrench 101. After the second fixture 51 is opened, it can be operated in exactly the same manner as the conventional indirect ratchet wrench 101.

  As described above, the posture holder 1 includes the posture regulating plate 21 that regulates the turning range of the ratchet main body 111, and the ratchet main body 111 is brought into contact with the first arm 131 that supports the ratchet main body 111 against the posture regulating plate 21. The posture with respect to the second arm 141 is maintained. For this reason, by attaching the posture holder 1 to the indirect ratchet wrench 101, it is possible to hold the posture of the ratchet main body 111 with respect to the second arm 141 before operating the indirect ratchet wrench 101. Thereby, the sockets 112 and 113 can be easily fitted into the bolts.

  Further, when the indirect ratchet wrench 101 is operated so as to tighten or loosen the bolt, the second fixture 51 is opened, and the support plate 42 moves to a position that does not interfere with the operation of the indirect ratchet wrench 101. The function of the wrench 101 is maintained, and the bolt tightening operation and the bolt loosening operation can be performed without hindrance.

  Next, the indirect ratchet wrench posture holder 2 according to the second embodiment of the present invention will be described. FIG. 7 is a view illustrating a state in which the indirect ratchet wrench 2 of the second embodiment is attached to the indirect ratchet wrench 101 and the indirect ratchet wrench 101 is operated. The same components as those of the indirect ratchet wrench holding device 1 of the first embodiment shown in FIG. 1 to FIG.

  The indirect ratchet wrench posture retainer 2 (hereinafter referred to as posture retainer 2) of the second embodiment is the same as the posture retainer 1 except for the attachment procedure of the support plate 42 and the turning direction of the support plate 42. It is the same, and the effect is also the same as that of the posture holder 1. In addition, the state which attached the attitude | position holder 2 to the indirect ratchet wrench 101 becomes FIG.

  In the posture holder 1, the support plate 42 is attached to the base plate 11 through the hinge 45 so that the base end 43 is pivotable. However, in the posture holder 2, the support plate 42 has a part 44 on the upper side. It is attached to the lower end of the attitude | position control board 21 via a hinge (illustration omitted) so that rotation is possible. For this reason, when the left and right band members 52 and 53 are separated in accordance with the operation of the indirect ratchet wrench 101, the support plate 42 pivots upward from the hinge as a starting point and becomes substantially horizontal by the action of the spring provided in the hinge. Thereby, the bolt tightening operation and the bolt loosening operation can be performed without any trouble.

  In the posture holder 2, when the band members 52 and 53 are separated, the support plate 42 is swung to the horizontal position. The position of the support plate 42 when the band members 52 and 53 are separated is the bolt tightening operation. Any position can be used as long as the bolt can be loosened without any trouble.

  As shown by the indirect ratchet wrench posture holders 1 and 2 of the first and second embodiments, the direction of the support plate 42 that opens when the band members 52 and 53 are cut off is the vertical direction even if it is the horizontal direction. May be.

  Next, an indirect ratchet wrench posture holder 3 according to a third embodiment of the present invention will be described. FIG. 8 is a view showing a state in which the indirect ratchet wrench holding tool 3 according to the third embodiment of the present invention is attached to the indirect ratchet wrench 101. The same components as those of the indirect ratchet wrench holding device 1 of the first embodiment shown in FIG. 1 to FIG.

  The indirect ratchet wrench posture holder 3 (hereinafter referred to as the posture holder 3) of the third embodiment is the same as the posture holder 1 except for the shape of the substrate 12 and the structure of the support body 41. The effect is basically the same as that of the posture holder 1. The support body 41 of the posture holder 3 is provided with a block member 49 that fills the gap between the support plate 42 and the connecting portion 145 of the second arm 141.

  The substrate 11 of the posture holder 1 has a rectangular shape and the same width in the height direction. For this reason, the distance between the left and right attitude regulating plates 21 and the distance between the left and right support plates 42 are the same. On the other hand, the substrate 12 of the posture holder 3 is provided with a step at the intermediate portion, and the width of the lower portion is narrower than that of the upper portion.

  The width of the upper part of the substrate 12 is the same as that of the substrate 11, and the width of the left and right posture regulating plates 21 is also the same as the width of the left and right posture regulating plates 21 of the posture holder 1. On the other hand, the width of the lower portion of the substrate 12 is set such that the distance between the left and right support plates 42 is the same as the outer diameter of the bearing 143 of the second arm 141.

  The block member 49 has a rectangular parallelepiped shape and is bonded to the back surfaces of the left and right support plates 42. The block member 49 is provided so as to come into contact with the connecting portion 145 when the posture holder 3 is attached to the indirect ratchet wrench 101. The block member 49 is made of the same material as the support plate 42, and the support plate 42 and the block member 49 may be integrally formed.

  In the case of the posture holder 1, when it is attached to the indirect ratchet wrench 101, the substrate 11, the first fixture 31 and the second fixture 51 abut against the indirect ratchet wrench 101 and hold its position. There is a space between the support plate 42 and the second arm 141, and the support plate 42 is not in contact with the second arm 141. On the other hand, in the posture retainer 3, when attached to the indirect ratchet wrench 101, the support plate 42 and the block member 49 in addition to the substrate 12, the first fixture 31 and the second fixture 51 are attached to the indirect ratchet wrench 101. Since it abuts, it is mounted in a very stable state.

  Since the support plate 42 is in contact with the second arm 141 before the indirect ratchet wrench 101 is operated in the posture holder 3, the second fixture 51 is released immediately after the indirect ratchet wrench 101 is operated. As described above, the posture holding tool 1 and the posture holding tool 3 are different in timing when the second fixing tool 51 is opened, but both of them can operate the indirect ratchet wrench 101 without any trouble.

  The indirect ratchet wrench holding tool according to the present invention is not limited to the above-described embodiment, and can be changed and used without changing the gist. For example, in the indirect ratchet wrench posture holders 1, 2, and 3 of the first to third embodiments, the support plate 42 is forcibly moved by the action of the spring when the second fixture 51 is opened. The support plate 42 may not be moved when the two fixing tools 51 are opened. If the second arm 141 is brought into contact with the indirect ratchet wrench 101 and is rotated (rotated) together with the second arm 141, the operation of the indirect ratchet wrench 101 is not obstructed.

  In the indirect ratchet wrench holding tools 1, 2, and 3, the first fastener 31 includes the surface fasteners 34 and 38 on the band members 32 and 35, and the second fastener 51 includes the surface fasteners 54 on the band members 52 and 53. 55, and these are connected, but the connecting means of the band members 32, 35, 52, 53 may be other than the hook-and-loop fastener.

  For example, a claw or a protrusion may be provided on one of the band members 32, a groove for engaging the claw or the protrusion may be provided on the other band member 35, and the band members 32 and 35 may be connected by the claw or protrusion and the groove. Moreover, since the 1st fixing tool 31 is not opened after attaching to the indirect ratchet wrench 101, a button etc. may be sufficient.

  Moreover, in the indirect ratchet wrench posture holders 1, 2, and 3, the first fixture 31 is attached to the vertical portion 134 below the bearing 133 of the first arm 131, but the position of the first fixture 31 is increased, You may attach to the support shaft 115 of the ratchet main body 111. FIG. Moreover, although the indirect ratchet wrench attitude | position holders 1, 2, and 3 of 1st-3rd embodiment are formed with the synthetic resin material, you may manufacture using a metal material.
