Summary of the Invention

Problems to be Solved by the Invention

[0006] In the hanging tool composed of the above-described holder body and the detachable member, in the hanging state of the portable tool, basically the locking portion is in a fixed state (in Patent Document 2, it can be forcibly rotated for detachment, but it is fixed by spring pressure in the normal state). Therefore, for example, when the portable tool is hung as shown in FIG. 3 and the operator assumes a bent posture, the tip of the portable tool or the tool holding member hits the floor surface at the feet, etc., which interferes with the work.

[0007] In particular, when the tool holding portion is connected by a pivot shaft as described in Patent Document 3, since the tool holding portion can swing, in the working posture of FIG. 3 above, the tool holding portion will not tilt and interfere, but it will swing even in the normal state, lacking stability during carrying.

[0008] Therefore, the present invention proposes a hanging tool for a portable tool that is in a fixed state normally and can be in a swingable state depending on the working posture.

Means for Solving the Problems

[0009] The hanging tool for a portable tool according to claim 1 of the present invention is composed of a holder body provided with a detaching and attaching mechanism to a belt on the back side and a holding groove with an upward opening on the front side, and a detachable member provided with an appropriate tool holding portion and a locking portion inserted and attached to the holding groove from above on the back. The locking portion of the detachable member is formed in a shape that can rotate in the holding groove, and a fitting recess is provided downward. A locking receiving portion provided with a locking protrusion into which the fitting recess fits is provided below in the holding groove of the holder body. A retaining mechanism provided with a retaining protrusion of the locking portion is provided at a position that allows the fitting recess to be detached from the locking protrusion above in the holding groove.

[0010] Thus, the holder body is attached to the operator's belt, the detachable member is attached by inserting the locking portion into the holding groove of the holder body, and the portable tool is held by the detachable member and carried. In particular, when the locking portion is in a state where the fitting recess of the locking portion is fitted to the locking projection by the weight of the detachable member (including the portable tool) (the state shown in Fig. 3(a)1), the swinging of the detachable member is suppressed and it becomes a fixed state. When an external force (such as when colliding with an obstacle on the floor surface) is applied to the detachable member due to a change in the operator's posture (Fig. 3(b)) and the fitting recess of the locking portion is detached from the locking projection (the state shown in Fig. 3(a)2), the detachable member becomes a swingable state (the state shown in Fig. 3(a)3) and swings appropriately so that the detachable member does not interfere with the operator.

[0011] Also, the hanging tool for the portable tool according to claim 2 of the present invention is formed such that the locking projection and the fitting recess are triangular, so that the detachable member can be rotated by an appropriate external force applied to the detachable member, particularly when the fitting recess and the locking projection are in a fitted state. During normal carrying, the swinging is suppressed by the weight of the detachable member as described above. When an external force is applied to the detachable member from the lateral direction during the operator's operation (Fig. 6), the locking portion (detachable member) rotates and the fitting recess of the locking portion is detached from the locking projection, and the detachable member does not interfere with the operator.

[0012] Also, the hanging tool for the portable tool according to claim 3 of the present invention is particularly composed of a mounting body having a locking portion and a mounting portion for the tool holding body, a tool holding structure as appropriate, and a tool holding body mounted on the mounting portion. It can be combined with a tool holding body corresponding to the type of tool to be carried with respect to a common mounting body (having a swing fixing mechanism).

[0013] Moreover, the suspension tool for the portable tool according to claim 4 of the present invention further comprises a belt attachment / detachment mechanism of the holder body, which is composed of an insertion plate hinged to the upper edge of the back surface of the holder body and a movable locking part for locking the lower part of the insertion plate provided below the main body. The hinge connection is a click structure that can be click-locked at an appropriate angle. When carrying the portable tool, the insertion plate of the holder body is inserted inside the operator's belt in a state where it is widely opened, and the main body of the holder body can be maintained at an appropriate angle by the click structure. After attaching the attachment / detachment member in this state, the main body is rotated toward the belt side and locked, making the belt attachment operation easier.

Advantages of the Invention

[0014] The configuration of the present invention is as described above. In the suspended state of the portable tool, it is normally fixed by the weight of the portable tool or the like. When an external force is applied to the carrying part due to the operator's posture, the fitting recess of the locking part of the attachment / detachment member is separated from the locking protrusion and becomes swingable, providing a novel suspension tool for a portable tool that does not interfere with the operator's work.

Embodiments for Carrying Out the Invention

[0016] Next, embodiments of the present invention will be described. The suspension tool for a portable tool shown in the embodiment is composed of a holder body C attached to a belt B of an operator A and a detachable member D that holds the tool and is detachable from the holder body C.

[0017] The holder body C is provided with a belt attachment / detachment mechanism 2 for attaching / detaching to / from the belt B and a member attachment / detachment mechanism 3 for attaching / detaching the detachable member D to / from the main body portion 1. The belt attachment / detachment mechanism 2 is composed of an insertion plate 21 hinge-connected to the upper edge of the back surface of the main body portion 1 and a movable lock portion 22 provided below the main body portion 1 so as to be vertically movable with downward biasing and having a hook portion 221 provided at the lower end of the back. In particular, the insertion plate 21 forms a connection hole portion 211 such as a safety cord at the lower end and a hook receiving portion 212 where the hook portion 221 of the movable lock portion 22 is hooked, and the hinge connection has a click structure that stops at positions with opening angles of 45°, 90°, and 130°.

[0018] Also, a member attachment / detachment mechanism 3 is provided on the front side of the main body portion 1. The member attachment / detachment mechanism 3 is composed of eaves portions 31 on both sides of the main body portion 1 and a locking receiving portion 32 below, forming a holding groove 33 corresponding to the thickness of a locking portion described later, and a retaining mechanism 34 is provided above in the holding groove 33.

[0019] In particular, the locking receiving portion 32 is provided with a fitting recess 411 of a locking portion 41 described later inserted therein and a locking protrusion 321. The particularly illustrated example has a trapezoidal shape with the locking protrusion 321 slightly raised.

[0020] The retaining mechanism 34 is composed of a retaining protrusion 341 provided at a position where the locking portion in the holding groove 33 fits between the locking protrusion 321 and an operation lever 342 for operating the protruding / retracting movement of the retaining protrusion 341 into / from the holding groove 33.

[0021] The retaining projection 341 is biased in the protruding direction, but its upper surface is formed as an inclined surface so that it is in a buried state against intrusion from above, and it collides with the lower surface against escape from below to exert a retaining function. Its formation position is provided at a position that allows the operation of the following locking portion 41. The operation lever 342 is provided protruding from the upper part of the main body 1.

[0022] The detachable member D is composed of a mounting body 4 and a tool holder 5. The mounting body 4 has a locking portion 41 protruding from the back surface, a mounting portion 42 for the tool holder 5 (the illustrated example shows a connecting bar) on the front surface, and an operation knob 43 provided upward.

[0023] The locking portion 41 fits into the holding groove 33 and is rotatable within the holding groove 33. A fitting recess 411 corresponding to the locking projection 321 is provided below, and it is sized to fit within the range of the locking receiving portion 32 and the retaining projection 341.

[0024] The tool holder 5 has, for example, a tool insertion portion 5a shown in Fig. 5(a), a caliper 5b shown in Fig. 5(b), a structure necessary for carrying the tool, and a mounting structure corresponding to an appropriate mounting portion 42 provided on the mounting body 4, and is an appropriate structure suitable for carrying the tool corresponding to the work of the operator.

[0025] Thus, for the above-described hanging tool, the tool holder 5 (appropriate members such as the tool insertion portion 5a and the caliper 5b) is mounted on the mounting body 4 to pre-form the detachable member D. The holder main body C is mounted on the belt B of the operator A. With the insertion plate 21 of the holder main body C wide open, it is inserted inside the belt B, and the main body portion 1 of the holder main body C is maintained at an appropriate angle by a click structure, and the detachable member D is mounted. Then, the main body portion 1 may be mounted on the belt B, or after fixing the holder main body C to the belt B, the detachable member D may be mounted.

[0026] The holder body C is attached to the belt B by inserting the insertion plate 21 inside the belt B and pushing the main body portion 1 toward the insertion plate 21. Then, the hook portion 221 of the movable locking portion 22 collides with the hook receiving portion 212 and is pushed upward against the downward biasing force of the movable locking portion 22. The hook portion 221 is hooked on the hook receiving portion 212 to complete the attachment. When detaching the holder body C from the belt B, push up the movable locking portion 22 against the downward biasing force and rotate the main body portion 1 outward to release the connection between the main body portion 1 and the insertion plate 21.

[0027] The attachment member 4 (detachable member D) is attached to the main body portion 1 of the holder body C by inserting the locking portion 41 from above into the holding groove 33 of the main body portion 1 and positioning it between the locking receiving portion 32 and the retaining projection 341, and then holding the locking portion 41 within the holding groove 33. Detachment is performed by grasping the operation knob 43 of the attachment member 4 and the operation lever 342 of the retaining mechanism 34 and pulling up the attachment member 4 with the retaining projection 341 in a buried state (Fig. 1(l)).

[0028] During the above-mentioned holding, in the state where the fitting recess 411 of the locking portion 41 is fitted to the locking projection 321 of the locking receiving portion 32 (the state in Fig. 3(a)1), the fitting state is maintained by the weight of the detachable member D, and the tool is carried while the swinging of the detachable member D is suppressed.

[0029] In particular, when the detachable member collides with the floor surface (obstacle E) and is lifted due to a change in the posture of the operator A (Fig. 3(l)1), the fitting recess 411 of the locking portion 41 detaches from the locking projection 321 (the state in Fig. 3(a)2), and it becomes a swingable state (the state in Fig. 3(a)3), and the detachable member D swings appropriately (Fig. 3(l)2) without interfering with the operator.

[0030] Further, if the shapes of the locking projection 321a and the fitting recess 411a are formed in a triangular shape (substantially obtuse triangle) as shown in FIG. 5, the swinging is suppressed by the self-weight of the detachable member D during normal carrying. For example, when the detachable member D collides with the upright post (obstacle E) during the operation of the operator A as shown in FIG. 6 and an external force is applied to the detachable member D from the lateral direction (FIG. 6), the detachable member D (locking portion 41) rotates and the fitting recess 411a of the locking portion 41 disengages from the locking projection 321a, so that the detachable member D does not interfere with the operation of the operator A.

[0031] In addition, if the locking portion 41 is provided on the mounting body 4 with the top and bottom reversed (FIG. 4C), it can be used as a hanging tool in a state where it can always swing.

[0032] As described above, the hanging tool for the portable tool of the present invention hangs and carries the tool. In particular, when the tool holding portion (detachable member D) hung by the posture of the operator A collides with an obstacle E such as the floor surface, it shifts to a swingable state without interfering with the operation of the operator, and when it returns to the normal hanging state, the swinging is suppressed.
