The mounting piece 21 is mounted on one side surface of the battery mounting portion 13, that is, on the right side surface of the impact driver 10 shown in FIG. That is, it extends in the longitudinal direction of the tool main body 12 . The carabiner hook 20 has a locking piece 22 extending along the mounting piece 21 and facing the mounting piece 21 .

A first opening operation piece 23 a is provided between one end of the mounting piece 21 and one end of the locking piece 22 , and the opening operation piece 23 a extends downward from the mounting piece 21 . The opening operation piece 23a continues between the mounting piece 21 and the locking piece 22 and is provided integrally therewith. Similarly, a second opening operation piece 23b is provided between the other end of the mounting piece 21 and the other end of the locking piece 22, and the opening operation piece 23b extends downward from the mounting piece 21. ing. The opening operation piece 23b continues between the mounting piece 21 and the locking piece 22 and is provided integrally therewith. Thus, the illustrated carabiner hook 20 has two openings, one opening operation piece 23a provided on one end side of the mounting piece 21 and another opening operation piece 23b provided on the other end side. It is a twin type equipped with an operating piece. A locking piece 22 is connected to the lower end of each of the opening operation pieces 23a and 23b.

As shown in FIG. 6(C), the locking piece 22 is provided with a bent portion 24 that is bent outward, that is, in a direction away from the housing 14 of the impact driver 10, in a chevron shape. The bent portion 24 is inclined toward the attachment piece 21 as shown in FIGS. 5(B) and 5(C). A belt hook 25 consisting of an engaging tongue is provided on the bent portion 24, and the belt hook 25 extends along the opening operation pieces 23a and 23b.

The belt hook 25 is arranged outside the impact driver 10 relative to the opening operation pieces 23a and 23b, and the impact driver 10, which is a device, is directly hooked to the user's belt or directly hooked to various members such as a stepladder. used to Between the belt hook 25 and the inner opening operation pieces 23a and 23b, a gap 26 into which the belt is inserted is formed, as shown in FIGS. 5(B) and 5(C). To facilitate engagement of the belt hook 25 with the user's belt, the tip 25a of the belt hook 25 is slightly slanted outward.

When the belt hook 25 is engaged with the user's belt, the impact driver 10 is set in a hanging posture so that the tool main body 12 faces downward, as shown in FIG. 1 and 2 show a state in which the tool main body 12 is on the upper side. This state is the basic posture in which the impact driver 10 is normally used. do.

As shown in FIG. 5A, the two opening operation pieces 23a and 23b are bilaterally symmetrical with respect to the central portion of the mounting piece 21 in the longitudinal direction, that is, the central portion of the belt hook 25 in the width direction. In this manner, the opening operation pieces 23a and 23b are arranged symmetrically with respect to the central portion of the mounting piece 21 in the longitudinal direction on the left and right sides of the carabiner hook 20. As shown in FIG.

When hanging the impact driver 10 from the user's belt via the loop-shaped carabiner 30, the impact driver 10 is hung from the carabiner 30 so that the tool main body 12 faces downward, as shown in FIG. be done. When the impact driver 10 is in the hanging posture by locking the locking piece 22 to the carabiner 30, the locking piece 22 of the carabiner hook 20 is positioned above the mounting piece 21 as shown in FIG. As shown in FIG. 8A, the carabiner 30 includes a turning rod portion 33 that is rotatably mounted on a turning support portion 32 provided on the belt 31, and a gate that can be opened and closed around a pin 34. The swivel rod portion 33 and the detachable rod portion 36 are integrally connected by upper and lower arm portions 37 and 38, forming a loop shape as a whole.

When the carabiner hook 20 is engaged with the carabiner 30 and the gate 35 is moved to open around the pin 34 so as to approach the belt 31, a gate opening space for attachment and detachment is formed in the attachment/detachment rod portion 36 . be. Thus, when the locking piece 22 of the carabiner hook 20 is pressed against the gate 35 from the outside, the gate 35 is opened and the locking piece 22 of the carabiner hook 20 is locked to the carabiner 30 . A spring force is applied to the gate 35 in a direction to close the gate space, and the gate open space is kept closed unless the gate 35 is pressed from the outside. FIG. 8 shows a state in which the carabiner hook 20 is engaged with the carabiner 30, and the impact driver 10, which is a device, has the tool main body 12 on the distal end side facing downward, and the battery mounting portion 13 and the battery 15 are located at the proximal ends. The locking piece 22 of the carabiner hook 20 is locked to the carabiner 30 with the part side facing upward. The impact driver 10 is suspended from the belt 31 in this state.

In order to remove the impact driver 10 suspended from the belt 31 via the carabiner 30 from the carabiner 30, the impact driver 10 is moved from the suspension posture shown in FIG. 4 to the usage posture shown in FIGS. Move in reverse. At this time, the reversal movement of the impact driver 10 causes the carabiner hook 20 to be reversed in the direction indicated by the arrow R in FIG. 8(B). The end portion of the locking piece 22 on the side of the opening operation piece 23 a constitutes a fulcrum portion 41 . When the impact driver 10 is reversely moved to the use posture, the boundary portion between the detachable rod portion 36 and the arm portion 38 of the carabiner 30 contacts the fulcrum portion 41 forming the contact portion, and the carabiner hook 20 contacts the fulcrum portion 41 portion. As the center, it reversely moves so as to slide on the outer peripheral surface of the arm portion 38 . Thus, the locking piece 22 locks the carabiner 30 when the impact driver 10 is suspended, and the fulcrum portion 41 at the end of the locking piece 22 on the side of the opening operation piece 23a is turned when the impact driver 10 is turned. form the center of action. The opening operation piece 23 a has a curved portion 42 from the fulcrum portion 41 to the mounting piece 21 .

The bent portion 42 connects a bent portion 43 bent in a direction projecting toward the belt hook 25 on the front surface shown in FIGS. 5A and 8B and the mounting piece 21 of the opening operation piece 23a. At the end, there is a bent portion 44 bent in a direction away from the belt hook 25 , and both bent portions 43 and 44 are integrated by an intermediate portion 45 . As shown in FIGS. 5B and 5C, the bent portion 43 is bent outward toward the intermediate portion 45, and the bent portion 44 is bent inward from the intermediate portion 45. is doing. Therefore, the curved portion 42 consisting of the bent portions 43 , 44 and the intermediate portion 45 protrudes outward, that is, away from the housing 14 of the impact driver 10 .

As described above, when the carabiner hook 20 is reversely moved about the abutting portion, that is, the fulcrum portion 41, the curved portion 42 of the opening operation piece 23a is bent between the curved portion 43 and the intermediate portion as shown in FIG. 9(B). The portion 45 crosses the detachable rod portion 36 from the inner side to the outer side, and the portions of the intermediate portion 45 and the bent portion 44 contact the gate 35 along the direction of crossing the outer surface of the gate 35 . At the start of contact, first, the projecting portion 46 contacts the outer surface of the gate 35 on the tip side.

Therefore, when the impact driver 10 is reversed to the use posture, the fulcrum portion 41 of the opening operation piece 23a is positioned inside the carabiner 30, and the curved portion 42 meanders from the inside to the outside of the carabiner 30 to move the detachable rod portion 36 inside. Since the protrusion 46 abuts on the outer surface of the gate 35 in a direction that traverses the outer surface of the gate 35, a pressing force in the opening direction is applied to the gate 35 from the protrusion 46 or the curved portion 42. . As a result, when the impact driver 10 is reversed from the suspension posture to the use posture, the reversing operation force automatically opens the gate 35 of the carabiner 30, and the locking state between the carabiner 30 and the locking piece 22 is released. be done.

The opening operation piece 23a is provided with a projecting portion 46 as shown in FIG. 5(A). The protruding portion 46 protrudes outward in the front-rear direction of the housing 14 from the mounting piece 21 and is inclined toward the housing 14 as shown in FIGS. 5(B) and 5(C). When the carabiner hook 20 is reversed from the hanging posture to the use posture, the protruding portion 46 crosses and abuts the outer surface of the gate 35 of the carabiner 30 so that the gate 35 can be smoothly opened.

As shown in FIG. 5A, the opening operation piece 23a meanders in an S shape as a whole when viewed from the front direction. Moreover, as shown in FIG. 5(C), when viewed from the right side, it has a meandering S shape as a whole. Therefore, when viewed from the plane side or the bottom side, the opening operation piece 23a has a helical shape in the longitudinal direction, as indicated by broken lines in FIGS. 6(B) and 6(C). With respect to this spiral shape, if miniaturization is given priority, the same effect can be obtained if either one of them is S-shaped when viewed from the front side or the right side.

The second opening operation piece 23b is arranged symmetrically with respect to the longitudinal central portion of the mounting piece 21 with respect to the first opening operation piece 23a. Therefore, like the opening operation piece 23a, the opening operation piece 23b also has the curved portion 42 and the protruding portion 46, and redundant description is omitted. As shown in FIG. 6A, the second opening operation piece 23b meanders in an S shape when viewed from the rear side.

The carabiner hook 20 has opening operation pieces 23a and 23b and a belt hook 25. However, when the carabiner hook 20 is not directly engaged with the user's belt, the carabiner can be used with the belt hook 25 removed. can be a hook.

The carabiner hook 20 is attached to the housing 14 of the impact driver 10 at the attachment piece 21 . The mounting piece 21 is movably assembled to a sleeve 51 attached to the housing 14, as shown in FIGS. A rear surface of the mounting piece 21 is provided with a protrusion 52 that is inserted into a positioning groove formed in the housing 14 . Two mounting holes 53a and 53b are provided through the sleeve 51 in the thickness direction, and the sleeve 51 is mounted to the housing 14 by a screw member 54 mounted in one of the mounting holes 53a. The housing 14 is provided with a screw hole into which the screw member 54 is screwed. Carabiner hook 20 is secured in place on housing 14 by a single screw member 54 by inserting protrusion 52 into the groove.

The sleeve 51 has a through hole formed corresponding to the cross-sectional shape of the mounting piece 21, and the mounting piece 21 is movably held in the through hole. The screw member 54 passes through an elongated hole 55 formed in the mounting piece 21 so as to extend in the longitudinal direction. A spring holder 56 projecting into the elongated hole 55 is provided on the rear side of the sleeve 51 , and the spring holder 56 holds a spring member composed of a leaf spring 57 and a spring switch 58 . The inner surface of the slot 55 is provided with two longitudinally spaced notches or grooves 59a and 59b, and the spring switch 58 pushes the leaf spring 57 upward to 57 is operated to disengage. The spring switch 58 is covered by a spring switch cover 50 attached to the front side of the sleeve 51 , and the spring switch cover 50 is attached to the spring switch 58 . The spring switch cover 50 functions as an operating portion operated by the user when sliding the carabiner hook 20 along the sleeve 51 . The spring switch 58 and the spring switch cover 50 can be fixed more securely when the leaf spring 57 is engaged with the notch groove to fix the carabiner hook 20 to the sleeve 51 .

Spring switch 58 and spring switch cover 50 are provided to allow easier sliding of carabiner hook 20 along sleeve 51 . However, even if the spring switch 58 and the spring switch cover 50 are not provided, the same operation can be performed by moving the carabiner hook 20 with a finger, although the smoothness is somewhat lost.

The inner surface of the slot 55 is provided with two longitudinally spaced notches or grooves 59a, 59b. As shown in FIG. 2, the sleeve 51 is attached to the battery mounting portion 13 of the housing 14 by the screw member 54, and the first opening operation piece 23a is protruded behind the battery mounting portion 13, as shown in FIG. 7(C). , the leaf spring 57 is engaged with the cutout groove 59a. Thus, in a state in which the opening operation piece 23a is shifted rearward from the side surface of the battery mounting portion 13 and the leaf spring 57 is engaged with the notch groove 59a, the carabiner hook 20 does not move with a weak external force. The carabiner 30 can be easily locked to the hook 20. - 特許庁Since the plate spring 57 is engaged with the notch groove 59a, the free movement of the carabiner hook 20 is suppressed when the impact driver 10 is suspended via the carabiner 30. As shown in FIG.

When the carabiner 30 is not locked, the opening operation piece 23a is shifted to the left side in FIG. When the carabiner hook 20 is shifted to the left, an external force is applied to the carabiner hook 20 to move the leaf spring 57 out of the notch groove 59a and engage with the notch groove 59b. In this state, carabiner hook 20 is prevented from moving freely when impact driver 10 is in use.

In the impact driver 10 described above, a carabiner hook 20 is attached to the left side surface of the housing 14 of the impact driver 10 as shown in FIG. When a right-handed user works with the handle portion 11 in the right hand, the carabiner 30 is positioned on the right side of the belt 31 attached to the user. , the carabiner hook 20 is attached to the left side of the housing 14 .

On the other hand, when a left-handed user hangs the impact driver 10 by locking it to the carabiner 30 , the carabiner hook 20 can be attached to the right side surface of the housing 14 . Therefore, the right side surface of the housing 14 is also provided with a positioning hole into which the protrusion 52 is inserted and a screw hole into which the screw member 54 is attached. The threaded hole provided on the left side of the housing 14 is coaxial with the threaded hole provided on the right side, and the groove provided on the left side faces the groove provided on the right side. When the carabiner hook 20 is attached to the right side surface of the housing 14, the opening operation piece 23b is on the rear end side of the impact driver 10 with respect to the opening operation piece 23a. Further, the screw member 54 is attached to the housing 14 through the attachment hole 53b of the sleeve 51 .

By removing the sleeve 51 with the screw member 54 in this manner, the carabiner hook 20 can be attached to either of the left and right side surfaces of the housing 14 . Carabiner hooks 20 can also be attached to both the left and right side surfaces of the housing 14, respectively.

FIG. 10 shows the main part of the impact driver 10 with carabiner hooks 20 attached to both left and right sides.

10(A) shows the impact driver 10 in a state in which one of the opening operation pieces of both carabiner hooks 20 protrudes rearward. The left carabiner hook 20 has an opening operation piece 23a that protrudes rearward from the battery mounting portion 13 at the base end of the impact driver 10, and the right carabiner hook 20 has an opening operation piece 23b that protrudes rearward. 10(B) shows the impact driver 10 in which both carabiner hooks 20 are shifted to the front side of the impact driver 10 so that they overlap the side surfaces of the battery mounting portion 13 and the battery 15, respectively. . In other words, the carabiner hook 20 is stored in the impact driver 10, and the carabiner hook 20 does not become an obstacle when the carabiner hook 20 is not used. Although FIG. 10 describes that the carabiner hook 20 slides in the front-rear direction of the impact driver 10, the same effect can be obtained even if the impact driver 10 rotates around the left-right direction of the impact driver 10, for example. In this way, the impact driver 10 as a device can be attached not only with one carabiner hook 20 but also with two carabiner hooks 20 . When one carabiner hook 20 is attached, the position can be changed from one of the left side and the right side of the housing 14 to the other.

As shown in FIG. 10, when two carabiner hooks 20 are attached, the sleeve 51 of the left carabiner hook 20 is attached to the housing 14 by a screw member 54 passing through the attachment hole 53a. On the other hand, the sleeve 51 of the right carabiner hook 20 is attached to the housing 14 by a screw member 54 passing through the attachment hole 53b. Also, when two carabiner hooks 20 are attached, a rivet may be used instead of the screw member 54 to prevent the sleeve 51 from coming off.

Next, an operation of hooking the carabiner hook 20 to the carabiner 30 and an operation of removing it from the carabiner 30 will be described with reference to FIGS. 11 and 12. FIG.
