[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook for hanging a portable tool on a worker's belt, for example, by hanging it on a waist, and more particularly, it is easy to use when hanging a right-handed or left-handed person. In view of the above, the present invention relates to a hook which can be attached to any of the left and right sides of the portable tool.

[0002]

2. Description of the Related Art Conventionally, a hook of a portable tool is usually set at a position that is convenient for a right-handed worker, so that it is difficult for a left-handed worker to use the hook. In view of this, the applicant of the present application has provided a hook that is easy to use for both right-handed and left-handed persons by making it possible to use the hooks in any of the left and right hand positions in Japanese Utility Model Application No. 3-90602 filed earlier.

[0005] As shown in FIGS. 5 and 6, the hook 4 has a substantially semicircular base 5 positioned along the circumferential direction of a substantially cylindrical portion of the housing 2 of the tool body 1, 5
Are bent inwardly in an L-shape, so that locking pieces 6 and 6 can be disengaged from engaging portions 3 and 3 formed in the housing 2.
And a substantially flat hooking piece 7 extending from the base piece 5 along the axial direction of the housing 2. The locking pieces 6, 6 are removed from the engaging portions 3, 3, and the hook 4 is attached to the housing 2. Change the position by 180 ° in the circumferential direction of
The position of the hook 7 can be changed from the left side to the right side of the housing 2 or vice versa by locking the hook 6 to the engaging portions 3 and 3.

[0004]

However, the hook 4 requires a separate member such as a spacer 10 or a screw in order to mount the hook 4 on the housing 2 more securely. However, there is a problem that a tool such as a screwdriver is required to change the attachment.

Therefore, the present invention does not require a separate member such as a spacer or a screw as described above, and therefore does not require a tool such as a screwdriver for changing the right and left.
Moreover, it is an object of the present invention to provide a portable tool hook which can be firmly attached so that the tool body does not come off easily even when a strong force is applied to the tool body in a suspended state.

[0006]

SUMMARY OF THE INVENTION For this purpose, the invention according to claim 1 is a hook which can be replaced on both left and right sides of a portable tool, and which is formed in a substantially U-shape. A gripping portion provided with a protrusion which can be elastically clamped at a suitable portion and which is engageable with a concave portion formed at a suitable portion of the portable tool on an inner surface of one side piece; With a hook piece extended in a folded shape from the tip of the side piece ,
Push one side piece of the gripping part against elasticity,
The engagement of the projections is released, and the grip portion is fitted to the portable tool.
It was configured to be removable from the site .

[0007]

According to the above construction, the hook is mounted by being clamped at a suitable portion of the tool by the elastic force of the grip portion, and in this mounted state, the projection provided on the side piece is formed at the suitable portion. It is in a state of being engaged with the formed concave portion. Therefore,
Since the hook is firmly mounted by the elastic force of the grip portion and the engagement of the projection with the concave portion, a separate member for mounting reinforcement such as a conventional spacer or screw is not required. For this reason, a tool such as a screwdriver is not required for replacement.

Further, since the hook piece is provided in a folded shape from the tip of one side piece of the grip portion, when the hook is attached to an appropriate portion and the portable tool is suspended, the grip piece is held. The part is in a state where it receives the above-mentioned appropriate position from below. Because the hook is received from below, the hook does not come off even if a strong force in the hanging direction is applied to the tool body. Further, since the force in the hanging direction acts as a force for pressing the one side piece against the tool main body, the engagement of the projection with the concave portion is further strengthened, and the hook comes off the tool main body also at this point. Never.

[0009] Even when a strong upward force is applied to the tool body, the engagement between the projection and the recess is maintained, so that the hook does not come off the tool body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, in this example, a case where a hook 20 described below is applied to an electric screwdriver (hereinafter simply referred to as a “tool 30”) as a portable tool will be described as an example. As shown, this tool 30
Is provided with a substantially D-shaped handle portion 31. The hook 20 of the present example is attached to a lower side portion of the handle portion 31 and at a position where it does not hinder the operator from gripping.

The hook 20 is formed by bending an elastic band plate material into a substantially S-shape. As shown in FIG. And a hook piece 22 provided continuously. Grip 21
Of the two side pieces 21a, 21b, the cut-and-raised protrusion 21d is formed on the inner side surface of the side piece 21b on the side where the hook piece 22 is provided.
Are formed. The tip side (side piece 21) of this projection 21d
The front end side of b, that is, the lower side in the figure) is formed as a smooth inclined surface, and the projection 21d is formed in a substantially wedge shape.

The above-described hooking piece 22 is formed continuously and folded from the tip of the side piece 21b on the near side in the drawing of the gripping portion 21 thus formed. This hook piece 22
Is slightly smoothly curved outward.

On the other hand, as shown in FIG. 3, a seat 32 for attaching the hook 20 is provided on a handle portion 31 of the tool 30.
Is provided. The seat 32 has a width slightly larger than the width of the grip portion 21 of the hook 20, and forms a step portion having a depth substantially equal to the plate thickness of the grip portion 21 on both side surfaces and the inner surface of the lower side of the handle portion 31. It is provided by that. Recesses 32a, 32a are provided at both ends of the seat 32. The two recesses 32a, 32a are provided on both sides of the handle portion 31 at positions where they are in a back-to-back relationship (see FIG. 4). .

With the above configuration, the hook 20 of this embodiment is used as follows. FIG. 4 shows how the hook 20 is used. FIG. 4 shows a state in which the tool 30 is hung on a belt 40 (41) as a hooking portion via the hook 20. Therefore, in this state, the tool 30 is in an upside down state (in FIG. (Upside down). The belt 40 is a belt for a right-handed worker, and the belt 41 is a belt for a left-handed worker.

It is assumed that the mounting position of the hook 20 indicated by the solid line in the drawing is a position convenient for the right-handed worker (the position for right-handed use), and therefore the mounting of the hook 20 indicated by the two-dot chain line in the drawing. It is assumed that the position is a convenient position for a left-handed worker (left-handed position). Accordingly, when the hook 20 is attached to the right-handed position, the hook piece 22 is located on the left side in the figure with respect to the tool 30 (therefore, the worker's belt 40 is located on the left side in the figure),
When attached to the left-handed position, the hook piece 22
Is located on the right side in the figure (therefore, the worker's belt 40 is located on the right side in the figure).

First, in a state where the hook 20 is mounted at the right-handed mounting position, the grip 21 is in a state of receiving the lower side of the handle 31 along the seat 32 from below. Due to the elasticity of the pieces 21a and 21b, the handle portion 31 is sandwiched from both left and right sides. The protrusion 21d of the side piece 21b is in a state of being fitted into and engaged with the concave portion 32a on the left side of the seat 32 in the drawing.

To change the hook 20 attached to the right-handed position to the left-handed position in such a state, first, the hooking piece 22 is pulled out from the belt 40, the tool 30 is removed from the waist, and Hook piece 22 (or side piece 21b)
(Or both sides) in the direction (left side in the figure) to be pulled away from the handle portion 31 against its elasticity. As a result, the protrusion 21d is disengaged from the concave portion 32a, and the locking of both is released. Then, if the hook 20 is moved in the direction of pulling it away from the handle portion 31 (downward in the figure), the grip portion 21 is removed from the seat 32, so that the hook 20 is moved to the handle portion 31.
Removed from

Thereafter, the hook 20 is turned right and left,
In this state, the handle portion 31 is sandwiched between the side pieces 21a and 21b of the grip portion 21 so that the grip portion 21 is seated.
Fit into 2. At this time, since the projection 21d has a smooth inclined surface on the upper side in the figure, the side piece 21b is gradually pushed out, so that the grip portion 21 is fitted smoothly. If hook part 21 is fitted until projection 21d fits in crevice 32a, attachment of hook 20 will be completed. In this manner, the hook 20 is replaced from the right-handed position to the left-handed position, and the hook piece 22 is moved to the opposite side of the tool 30, so that the left-handed operator is more convenient to use. It will be in a state of being mounted in a good position.

When changing from the left-handed position to the right-handed position, the same operation as described above may be repeated. In this manner, the hook 20 can be easily changed from a right-handed position to a left-handed position or vice versa by mounting the hook 20 with the left and right inverted. Since the portion 21 is sandwiched between the handle portions 31 by the elasticity of the side pieces 21a and 21b in the closing direction, the hook 20 is
There is no easy departure from the one.

Here, let us consider a case where, for example, a strong force P1 in the hanging direction is applied to the tool 30 in a state where the tool 20 is hung on the belt 40 (41) with the hook 20 attached to any position. , This force P1 is
Since the force acts as a force P3 in the direction of pressing the side piece 21b on the side provided with the handle portion 31 against the handle portion 31, the projection 21d never comes off the concave portion 32a, and the handle portion 21 is more firmly gripped by the handle portion 31. In addition, since the grip portion 21 is sandwiched in a state of receiving the handle portion 31 from below, the hook 20 does not come off from the handle portion 31. Conversely, even when a strong upward force P2 is applied to the tool 1, the protrusion 21d is held in a state of being engaged with the concave portion 32a by the elasticity of the side piece 21b, so that the hook 20 is detached from the handle portion 31. I will not do it.

As described above, according to the hook 20 of the present embodiment, the hook 20 connects the grip 21 to the two side pieces 21a,
Since the handle portion 31 is sandwiched by the elasticity of the closing direction of the handle 21b to be mounted on the tool 30,
It can be mounted in a good condition without using a separate member such as a spacer 10 or a screw as in the related art. Further, when changing the left and right mounting positions, it is sufficient to remove the grip portion 21 from the handle portion 31 while expanding the side piece 21b against its elasticity, so that a conventional tool such as a driver is not required. .

Moreover, even when a strong force P1 in the hanging direction acts on the tool 30, this force P1 is
Since it acts as a force to more firmly clamp the handle 1 to the handle portion 31, the hook 20 does not easily come off. Conversely, even when the upward force P2 acts on the tool 30, the elasticity of the side piece 21b causes the protrusion 2
Since 1d is held in a state of being engaged with the concave portion 32a of the handle portion 31, the hook 20 does not come off.

[0023]

According to the present invention, it is possible to mount a hook of a type which can be changed between left and right on the tool body without using a separate member as in the related art. In addition, a tool such as a screwdriver is not required to change the left and right parts, and it can be easily attached and detached.

Further, when the tool is suspended from the waist belt or the like, the grip is in a state of receiving the tool from below and the projection is engaged with the concave portion. Therefore, a large force is applied to the tool in the hanging direction or upward, for example. The hook does not come off when loaded.
