Description

The present invention relates to a base end structure of a peeler and a peeler.

A stripper is known that strips the coating layer off an object to be stripped, such as an electric wire (e.g., a high-voltage cable).

As a related technique, Patent Document 1 discloses an insulation stripping tool. The insulation stripping tool described in Patent Document 1 has a large-diameter insertion-side tubular portion into which the end of the insulated electric wire is inserted, and a small-diameter delivery-side tubular portion from which the conductor with the insulation stripped is delivered. A stopper for adjusting the stripping length is disposed inside the delivery-side tubular portion. In addition, a fixing screw member for fixing the stopper is disposed so as to protrude outward from the delivery-side tubular portion.

When an operator grasps the delivery-side tubular portion of the insulation stripping tool described in Patent Document 1 to perform the insulation stripping operation, the operator's hand interferes with the fixing screw member. As a result, the fixing screw member may move, causing the position of the stopper fixed by the fixing screw member to change.

On the other hand, with the insulation stripping tool described in Patent Document 1, when an operator grasps the insertion side tubular portion to perform the insulation stripping operation, the operator's hand interferes with the stripped debris discharged from the insertion side tubular portion. As a result, the insulation stripping operation may be hindered.

First Embodiment
With reference to Figs. 1 to 12, the base end structure of the peeler 1A and the peeler 1A in the first embodiment will be described. Figs. 1 and 2 are schematic vertical cross-sectional views showing the peeler 1A in the first embodiment. Fig. 1 shows a state before the peeling object W is placed on the peeler 1A, and Fig. 2 shows a state after the peeling object W is placed on the peeler 1A.

Fig. 8 is a schematic cross-sectional view (a cross-sectional view perpendicular to the longitudinal central axis CL) showing yet another example of the one-way clutch mechanism M3. Fig. 9 is a schematic cross-sectional view (a cross-sectional view perpendicular to the longitudinal central axis CL) showing yet another example of the one-way clutch mechanism M4. Fig. 10 is a schematic cross-sectional view showing an example of the first operating unit 20. Fig. 11 is a schematic perspective view showing an example of the non-metallic part 22. Fig. 12 is an exploded cross-sectional view showing the peeler 1A in the first embodiment.

The peeler 1A in the first embodiment has a base end structure constituting the base end PP and a tip end structure constituting the tip end DP. The base end structure means, for example, the structure of the portion on the second direction DR2 side of the housing part 70 to which the peeler blade part 72 is attached, and the tip end structure means the structure of the housing part 70 (or the structure of the housing part 70 and the structure of the portion on the first direction DR1 side of the housing part 70). In the example shown in FIG. 1, the base end structure constituting the base end PP and the tip end structure constituting the tip end DP (more specifically, the housing part 70) are inseparable from each other. Alternatively, the base end structure and the tip end structure may be separable from each other.

The base end structure of the peeler 1A includes a stopper 12, a stopper guide 14, a first operating part 20, and a one-way clutch mechanism M. The tip end structure of the peeler 1A includes a peeler blade part 72 and a housing part 70.

2, the stopper 12 positions the end of the core wire W1 of the object to be peeled W. More specifically, the stopper 12 prevents the core wire W1 from moving beyond the stopper surface 12a of the stopper 12 in the second direction DR2. The stopper 12 can also be said to be a member that adjusts the peeling length L1 of the object to be peeled W (in other words, the length of the exposed portion of the core wire W1).

The object W to be stripped includes, for example, a core wire W1, which is a conductor, and a coating layer W2 (more specifically, an insulating coating layer) that covers the core wire W1. When the object W to be stripped is a high-voltage cable, the coating layer W2 is quite hard. In particular, the coating layer W2 tends to harden in winter. A large force is required to strip the hard and thick coating layer W2. For this reason, the work of stripping the coating layer using a conventional stripper places a large burden on the worker. Furthermore, when an unskilled worker performs the stripping work, the quality of the stripping is likely to be uneven. The stripper 1A in the first embodiment can solve such problems.

As illustrated in FIG. 1, the stopper guide 14 is a member that guides the stopper 12. The stopper guide 14 may be formed of a single part, or may be formed of an assembly of multiple parts.

In the example shown in FIG. 1, the stopper guide 14 has a hole (second hole 14h) that guides the stopper 12 in the first direction DR1. When the stopper 12 is moved and adjusted in the first direction DR1 along the stopper guide 14, the peeling length L1 of the object W to be peeled becomes shorter, and when the stopper 12 is moved and adjusted in the second direction DR2 along the stopper guide 14, the peeling length L1 of the object W to be peeled becomes longer. Note that the portion of the stopper guide 14 that is closer to the first direction DR1 than the stopper surface 12a functions as a core wire housing portion that houses the core wire W1. When the stopper 12 is adjusted in position along the stopper guide 14, the length of the core wire housing portion is also adjusted.

The first operating unit 20 applies a rotational force around the longitudinal center axis CL to the peeler blade 72. In other words, the first operating unit 20 and the peeler blade 72 are mechanically connected so as to be able to transmit a rotational force. For example, when the first operating unit 20 is rotated in the first rotational direction R1, the peeler blade 72 also rotates in the first rotational direction R1.

In the example shown in FIG. 1, the first rotation direction R1 means one rotation direction around the longitudinal central axis CL of the peeler 1A, and the first rotation direction R1 means, for example, a clockwise rotation direction around the longitudinal central axis CL when viewed in the direction toward the first direction DR1.

The one-way clutch mechanism M prohibits the first operating unit 20 from rotating relative to the peeler blade 72 in the first rotation direction R1. In this case, when the first operating unit 20 is rotated in the first rotation direction R1, the rotational force is transmitted to the peeler blade 72 via the operating force transmission mechanism including the one-way clutch mechanism M. As a result, the peeler blade 72 rotates together with the first operating unit 20 in the first rotation direction R1.

The one-way clutch mechanism M also allows the first operating part 20 to rotate relative to the peeler blade 72 in a second rotation direction R2 opposite to the first rotation direction R1. In this case, when the first operating part 20 is rotated in the second rotation direction R2, the rotational force is not transmitted to the peeler blade 72. As a result, the first operating part 20 can be rotated in the second rotation direction R2 while the position of the peeler blade 72 is maintained.

In the base end structure of the peeler 1A in the first embodiment, and in the peeler 1A, the first operating unit 20 is disposed on the base end side (in other words, on the second direction DR2 side) of the stopper guide 14. This allows the operator to grasp the first operating unit 20 and perform the peeling operation. In addition, interference between the operator's hand grasping the first operating unit 20 and the stopper 12 or the stopper guide 14 or the second operating unit 16 that adjusts the position of the stopper 12 is suppressed. In this way, the stopper 12, which positions the end of the core wire W1 of the object W to be peeled, is prevented from moving unintentionally.

In addition, in the operation using a conventional peeler, the worker must perform the steps of (1) gripping the peeler, (2) rotating the peeler in the first rotation direction R1, (3) releasing the peeler, and (4) gripping the peeler in another position, and the worker must repeat the steps (2) to (4) described above. In contrast, the base end structure of the peeler 1A in the first embodiment and the peeler 1A are provided with a one-way clutch mechanism M. Therefore, the worker can perform the peeling operation by alternately repeating the first rotation operation of rotating the first operating unit 20 in the first rotation direction R1 and the second rotation operation of rotating the first operating unit 20 in the second rotation direction R2 without releasing the first operating unit 20. This improves the efficiency of the peeling operation.

In addition, in the base end structure of the peeler 1A and the peeler 1A in the first embodiment, the first operating part 20 is disposed on the base end side of the stopper guide 14, and the base end structure of the peeler 1A and the peeler 1A are equipped with a one-way clutch mechanism M. Therefore, when the operator repeatedly performs the first rotation operation and the second rotation operation alternately, the stopper 12, which positions the end of the core wire W1 of the peeling object W, is prevented from moving unintentionally.

The above-mentioned effect is particularly noticeable when the second operating unit 16, which adjusts the position of the stopper 12, is disposed on the stopper guide 14.

In the example shown in FIG. 1, the second operating part 16 is connected to the stopper 12 via a rod-shaped connecting part 15. The second operating part 16 and the connecting part 15 may be configured as a single integrally formed part, or may be configured as an assembly of multiple parts.

As illustrated in FIG. 3, the stopper guide 14 may have a guide hole 141h that slidably guides the connecting portion 15. The guide hole 141h is, for example, an elongated hole extending along the first direction DR1.

In the example shown in FIG. 3, when the second operating unit 16 is operated in the first direction DR1, the position of the stopper 12 (and the connecting portion 15) moves in the first direction DR1. When the second operating unit 16 is operated in the second direction DR2, the position of the stopper 12 (and the connecting portion 15) moves in the second direction DR2.

The second operating unit 16 is preferably an operating unit that allows an operator to manually perform the unlocking operation of the second operating unit 16, the sliding operation of the second operating unit 16, and the fixing operation of the second operating unit 16 without using a tool such as a screwdriver. The second operating unit 16 is, for example, an operating knob.

When the second operating unit 16 that adjusts the position of the stopper 12 is disposed on the stopper guide 14, as can be seen from the above-mentioned Patent Document 1 (Registered Utility Model No. 3151876), the operator's hand is likely to touch the second operating unit. In contrast, in the first embodiment, the first operating unit 20 is disposed closer to the base end side (in other words, on the second direction DR2 side) than the stopper guide 14, so that the operator's hand holding the first operating unit 20 is prevented from touching the second operating unit 16.

However, as illustrated in FIG. 4, in the embodiment, it is not excluded that the second operating unit 16 that adjusts the position of the stopper 12 is disposed on the proximal side of the first operating unit 20. It is also not excluded that the second operating unit 16 is disposed inside the first operating unit 20.

In the example shown in FIG. 4, the connecting portion 15 connected to the second operating portion 16 and the first operating portion 20 engage with each other via an engagement mechanism such as a lock mechanism (not shown in FIG. 4). In the embodiment, it is preferable that the hand of an operator holding the first operating portion 20 does not substantially touch the second operating portion 16. Alternatively, or additionally, it is preferable that the position of the stopper 12 does not change even if the hand of an operator holding the first operating portion 20 touches the second operating portion 16.

With reference to Figures 1 to 12, we will explain optional additional configurations that can be adopted in the first embodiment.

(Flange portion 40)
The base end structure of the peeler 1A in the first embodiment and the peeler 1A may include a flange portion 40. In the example shown in Fig. 1, the flange portion 40 is disposed on the first operating part 20 (more specifically, on the end of the first operating part 20 on the first direction DR1 side).

The flange 40 prevents the operator's fingers from touching the stopper guide 14 (or the second operating part 16 arranged on the stopper guide 14). In this case, unintentional movement of the stopper 12, which positions the end of the core wire W1 of the object W to be peeled, is more effectively prevented.

In FIG. 1 (a longitudinal cross-sectional view through the longitudinal center axis CL of the peeler 1A), the height of the second operating part 16 (i.e., the height from the longitudinal center axis CL of the peeler 1A) is preferably smaller than the height of the flange 40 (i.e., the height from the longitudinal center axis CL of the peeler 1A). In this case, even if the operator's finger moves beyond the flange 40 toward the stopper guide 14, interference between the operator's finger and the second operating part 16 is suppressed. In addition, when the peeler 1A is placed on a placement surface such as a floor or ground, interference between the second operating part 16 and the placement surface is suppressed. With this configuration, unintentional movement of the stopper 12, which positions the end of the core wire W1 of the peeling object W, is more effectively suppressed.

In the example shown in FIG. 1, the flange 40 has a pressure-receiving surface 40a that allows the operator to apply a force in the first direction DR1. The pressure-receiving surface 40a is a surface that faces the base end side of the peeler 1A (in other words, a surface that generally faces the second direction DR2).

By pressing the pressed surface 40a in the first direction DR1, the object W to be peeled is effectively pressed into the peeler 1A. As a result, the width of the peeled coating layer (i.e., the coating layer W2 peeled off from the core wire W1) obtained by rotating the first operating part 20 in the first rotation direction R1 increases. In this way, it becomes possible to complete the peeling operation efficiently in a short time.

As described above, the flange portion 40 has two different effects: it prevents the operator's fingers from touching the stopper guide 14 (or the second operating portion 16 arranged on the stopper guide 14), and it makes it easier for the operator to apply a force in the first direction DR1.

Without the flange 40, the greater the force the operator applies to the first operating unit 20, the more likely the operator's fingers will slip toward the stopper guide 14. On the other hand, the smaller the force the operator applies to the first operating unit 20, the smaller the width of the peelable coating layer. In contrast, the flange 40 can be said to be a configuration that simultaneously increases the force the operator applies to the first operating unit 20 and prevents the operator's fingers from moving toward the stopper guide 14.

The pressed surface 40a of the flange 40 may be pressed by the side of the thumb and index finger of the operator's right hand. For example, when the operator is facing the outer surface (peripheral side surface) of the peeler 1A, it is expected that the pressed surface 40a of the flange 40 will be pressed by the side of the thumb and index finger of the operator's right hand.

Alternatively, the pressed surface 40a of the flange 40 may be pressed by the fingertips of the operator (e.g., the tip of the thumb, index finger, and/or middle finger). For example, when the operator is facing the base end surface 20e of the peeler 1A, it is expected that the pressed surface 40a of the flange 40 will be pressed by the fingertips of the operator.

When the second operating part 16 is disposed in the stopper guide 14, it is preferable that the second operating part 16 is disposed in an annular recess 140 defined by a surface including the outer peripheral surface 14a of the stopper guide 14 and the first surface 40b, which is the surface of the flange part 40 on the first direction DR1 side. In the example shown in FIG. 1, the recess 140 in which the second operating part 16 is disposed is an annular recess defined by the end surface 70e on the second direction DR2 side of the housing part 70, the outer peripheral surface 14a of the stopper guide 14, and the above-mentioned first surface 40b.

(Window portion 13)
As illustrated in Fig. 5, the stopper guide 14 may include a window portion 13 through which the stopper surface 12a of the stopper 12 can be seen. The stopper surface 12a is a surface that comes into contact with an end of the core wire W1 of the object W to be peeled. In the example illustrated in Fig. 5, the stopper surface 12a is a surface that faces the first direction DR1.

In the example shown in FIG. 5, the window portion 13 is configured by a hole portion 142h formed in the stopper guide 14. The hole portion 142h is, for example, an elongated hole portion extending in a direction along the first direction DR1. It is preferable that the window portion 13 (hole portion 142h) and the guide hole 141h are arranged in parallel.

When the stopper guide 14 has a window 13, the worker can easily recognize whether the end of the core wire W1 of the object to be peeled W has been inserted until it contacts the stopper 12. This allows the worker to finish the peeling operation at the appropriate time.

When the first operating unit 20 is positioned closer to the base end than the stopper guide 14, interference between the hand of the operator holding the first operating unit 20 and the window portion 13 is suppressed. In other words, the operator's hand does not obstruct visibility of the stopper surface 12a. In addition, when the first operating unit 20 is provided with a flange portion 40, interference between the hand of the operator holding the first operating unit 20 and the window portion 13 is even more effectively suppressed.

(Scale 17)
The stopper guide 14 may have a scale 17 indicating the set value of the skinning length L1. In the example shown in Fig. 5, the scale 17 and the window portion 13 are disposed adjacent to each other. This allows the operator to easily recognize the relationship between the position of the stopper 12 (more specifically, the stopper surface 12a) and the scale 17 (in other words, the set value of the skinning length L1). In the example shown in Fig. 5, the position of the stopper 12 is adjusted so that the set value of the skinning length L1 is 5.5 cm.

In the example shown in FIG. 5, the scale 17 is provided on the side wall 142w of the hole 142h formed in the stopper guide 14. In this case, the scale 17 is positioned near the inner circumferential surface of the stopper guide 14 (in other words, the scale 17 is positioned closer to the longitudinal center axis CL of the peeler 1A. This allows the operator to more easily recognize the relationship between the position of the stopper 12 and the scale 17.

(One-way clutch mechanism M)
A first example of a one-way clutch mechanism M that can be employed in the first embodiment (or the second embodiment described below) will be described with reference to FIG.

The one-way clutch mechanism M1 shown in FIG. 6 includes an inner member 51 and an outer member 56 arranged outside the inner member 51.

In the example shown in FIG. 6, the inner member 51 includes a ratchet gear 51a arranged in an annular shape around the longitudinal center axis CL of the peeler, and a shaft member 51b supporting the ratchet gear 51a. The inner member 51 (more specifically, the shaft member 51b) extends along the longitudinal center axis CL of the peeler.

In the example shown in FIG. 6, the outer member 56 includes an engagement member 56a that is biased in a direction toward the inner member 51 (more specifically, the ratchet gear 51a). The engagement member 56a is supported by a first portion 21 that constitutes at least a part of the first operating unit 20. In addition, in the example shown in FIG. 6, a biasing member 57 such as a spring is disposed between the outer member 56 and the first portion 21, and the biasing member 57 biases the outer member 56 in a direction toward the inner member 51.

In the example shown in FIG. 6, a bearing member 54 is disposed between the first portion 21 and the inner member 51 (more specifically, the shaft member 51b). The presence of the bearing member 54 allows smooth relative rotation of the first portion 21 with respect to the inner member 51.

In the example shown in FIG. 6, when the first operating unit 20 is rotated in the first rotation direction R1 in the first step ST1, the outer member 56 and the inner member 51 (more specifically, the ratchet gear 51a) that engages with the outer member 56 rotate integrally in the first rotation direction R1. In the example shown in FIG. 1, the peeler blade 72 is connected to the inner member 51 via the housing 70, the stopper guide 14, etc. Therefore, when the inner member 51 rotates in the first rotation direction R1, the peeler blade 72 also rotates in the first rotation direction R1. As a result, the peeler blade 72 peels the peeling target W (in other words, separates the coating layer W2 from the core wire W1).

On the other hand, in the example shown in FIG. 6, when the first operating unit 20 is rotated in the second rotation direction R2 in the second step ST2, the outer member 56 overcomes the ratchet gear 51a of the inner member 51 and rotates in the second rotation direction R2. Therefore, the first operating unit 20 and the outer member 56 rotate in the second rotation direction R2 while the rotation of the inner member 51 (and thus the peeler blade 72) is suppressed. Therefore, when the first operating unit 20 is rotated in the second rotation direction R2, the peeler blade 72 does not peel the object W to be peeled.

With reference to Figure 7, a second example of a one-way clutch mechanism M that can be used in the first embodiment (or the second embodiment described below) will be described.

The one-way clutch mechanism M2 shown in FIG. 7 includes an inner member 51 and an outer member 56 arranged outside the inner member 51.

In the example shown in FIG. 7, the inner member 51 includes an axial member 51b that extends along the longitudinal central axis CL of the peeler.

In the example shown in FIG. 7, the outer member 56 includes a base member 56c and an interposed member 56d such as a roller or a ball. The base member 56c is, for example, a ring-shaped member with a hole formed in the center. The base member 56c may be supported (more specifically, fixed) by the first part 21 described above, or may be formed integrally with the first part 21. The interposed member 56d is interposed between the base member 56c and the inner member 51. The interposed member 56d is biased by the biasing member 57 toward the inclined surface 560 (the inclined surface that is inclined so as to approach the surface of the inner member 51) of the base member 56c. As a result, in the default state, the interposed member 56d contacts the inclined surface 560 and the inner member 51. The biasing member 57 is, for example, a spring such as a coil spring or a leaf spring.

In the example shown in FIG. 7, when the first operating unit 20 is rotated in the first rotation direction R1 in the first step ST1, the interposing member 56d moves toward the area where the gap between the base member 56c and the inner member 51 is narrower. As a result, the interposing member 56d functions as a wedge member, and the outer member 56 (base member 56c and interposing member 56d) and the inner member 51 rotate integrally in the first rotation direction R1. In the example shown in FIG. 1, the peeler blade 72 is connected to the inner member 51 via the housing 70, the stopper guide 14, etc. Therefore, when the inner member 51 rotates in the first rotation direction R1, the peeler blade 72 also rotates in the first rotation direction R1. As a result, the peeler blade 72 peels the skin of the object to be peeled W (in other words, separates the coating layer W2 from the core wire W1).

On the other hand, in the example shown in FIG. 7, when the first operating unit 20 is rotated in the second rotation direction R2 in the second step ST2, the interposing member 56d moves toward the area where the gap between the base member 56c and the inner member 51 is wider. As a result, the interposing member 56d does not function as a wedge member, and the outer member 56 (the base member 56c and the interposing member 56d) rotates in the second rotation direction R2 relative to the inner member 51. In this way, the first operating unit 20 and the outer member 56 rotate in the second rotation direction R2 while the rotation of the inner member 51 (and thus the peeler blade 72) is suppressed. Therefore, when the first operating unit 20 is rotated in the second rotation direction R2, the peeler blade 72 does not peel the object W to be peeled.

With reference to Figure 8, we will explain a third example of a one-way clutch mechanism M that can be used in the first embodiment (or the second embodiment described below).

The one-way clutch mechanism M3 shown in FIG. 8 includes an inner member 51 and an outer member 56 arranged outside the inner member 51.

In the example shown in FIG. 8, the inner member 51 includes an axis member 51b and an interposed member 51d such as a roller or a ball. The axis member 51b extends along the longitudinal center axis CL of the peeler. The interposed member 51d is interposed between the axis member 51b and the outer member 56. The interposed member 51d is biased by the biasing member 52 toward the inclined surface 510 of the axis member 51b (the inclined surface that is inclined so as to approach the inner surface of the outer member 56). As a result, in the default state, the interposed member 51d contacts the inclined surface 510 and the outer member 56. The biasing member 52 is, for example, a spring such as a coil spring or a leaf spring.

In the example shown in FIG. 8, the outer member 56 includes a base member 56c. The base member 56c is, for example, a ring-shaped member with a hole formed in the center. The base member 56c may be supported (more specifically, fixed) by the first portion 21 described above, or may be formed integrally with the first portion 21.

In the example shown in FIG. 8, when the first operating unit 20 is rotated in the first rotation direction R1 in the first step ST1, the interposing member 51d moves toward the area where the gap between the outer member 56 and the shaft member 51b is narrower. As a result, the interposing member 51d functions as a wedge member, and the outer member 56 and the inner member 51 (shaft member 51b and interposing member 51d) rotate integrally in the first rotation direction R1. In the example shown in FIG. 1, the peeler blade 72 is connected to the inner member 51 via the housing 70, the stopper guide 14, etc. Therefore, when the inner member 51 rotates in the first rotation direction R1, the peeler blade 72 also rotates in the first rotation direction R1. As a result, the peeler blade 72 peels the skin of the peeling object W (in other words, separates the coating layer W2 from the core wire W1).

On the other hand, in the example shown in FIG. 8, when the first operating unit 20 is rotated in the second rotation direction R2 in the second step ST2, the interposing member 51d moves toward the area where the gap between the outer member 56 and the shaft member 51b is wider. As a result, the interposing member 51d does not function as a wedge member, and the outer member 56 rotates in the second rotation direction R2 relative to the inner member 51. In this way, the first operating unit 20 and the outer member 56 rotate in the second rotation direction R2 while the rotation of the inner member 51 (and thus the peeler blade 72) is suppressed. Therefore, when the first operating unit 20 is rotated in the second rotation direction R2, the peeler blade 72 does not peel the object W to be peeled.

With reference to Figure 9, we will explain a fourth example of a one-way clutch mechanism M that can be used in the first embodiment (or the second embodiment described below).

The one-way clutch mechanism M4 shown in FIG. 9 includes an inner member 51 and an outer member 56 arranged outside the inner member 51.

In the example shown in FIG. 9, the inner member 51 includes an axial member 51b that extends along the longitudinal central axis CL of the peeler.

9, the outer member 56 includes a base member 56c, a pin member 56e, and a cam member 56f. The base member 56c is, for example, a ring-shaped member with a hole formed in the center. In the example shown in FIG. 9, the base member 56c is integrally formed with the first part 21. Alternatively, the base member 56c may be fixed to the first part 21. The pin member 56e is attached to the base member 56c. The cam member 56f is supported by the pin member 56e so as to be rotatable around the pin member 56e. In addition, one end of the urging member 57 is connected to one end 561 of the cam member 56f. The urging member 57 is, for example, a spring member, one end of the urging member 57 is connected to the cam member 56f, and the other end of the urging member 57 is directly or indirectly attached to the base member 56c.

In the example shown in FIG. 9, when the first operating unit 20 is rotated in the first rotation direction R1 in the first step ST1, the contact point between the inner member 51 and the cam member 56f moves in a direction approaching one end 561 of the cam member 56f. As a result, the contact force between the inner member 51 and the cam member 56f increases, and the outer member 56 (base member 56c and cam member 56f) and the inner member 51 rotate integrally in the first rotation direction R1. In the example shown in FIG. 1, the peeler blade 72 is connected to the inner member 51 via the housing 70, the stopper guide 14, etc. Therefore, when the inner member 51 rotates in the first rotation direction R1, the peeler blade 72 also rotates in the first rotation direction R1. As a result, the peeler blade 72 peels the skin of the peeling object W (in other words, separates the coating layer W2 from the core wire W1).

On the other hand, in the example shown in FIG. 9, when the first operating unit 20 is rotated in the second rotation direction R2 in the second step ST2, the contact point between the inner member 51 and the cam member 56f moves in a direction away from one end 561 of the cam member 56f. As a result, the contact force between the inner member 51 and the cam member 56f does not increase, and the outer member 56 (base member 56c and cam member 56f) rotates in the second rotation direction R2 relative to the inner member 51. In this way, the first operating unit 20 and the outer member 56 rotate in the second rotation direction R2 while the rotation of the inner member 51 (and thus the peeler blade 72) is suppressed. Therefore, when the first operating unit 20 is rotated in the second rotation direction R2, the peeler blade 72 does not peel the object W to be peeled.

In the example shown in Figs. 6 to 9, the first step ST1 and the second step ST2 described above are repeatedly performed, thereby peeling the skin of the object to be peeled W. In addition, in the example shown in Figs. 6 to 9, the peeler 1A is equipped with a one-way clutch mechanism M, so that when the first step ST1 and the second step ST2 are repeatedly performed, the operator does not need to change the gripping position at which the first operating unit 20 is gripped. This allows the operator to quickly perform the peeling operation.

6 to 9, the second step ST2 can be performed simply by rotating the first operating unit 20 in the second rotation direction R2 relative to the peeler blade 72. In the example shown in FIG. 6 to 9, the first operating unit 20 does not need to be slid in the axial direction (the direction along the first direction DR1) relative to the peeler blade 72 during the second step ST2. Therefore, in the example shown in FIG. 6 to 9, the first step ST1 (peeling operation) and the second step ST2 (returning the rotation angle position of the first operating unit 20 to a position where the operator can easily apply force) can be performed simply by rotating the first operating unit 20 back and forth.

In the example shown in Figs. 6 to 9, the peeling work can be performed while maintaining the rotation angle position of the first operating unit 20 within an angle range where the worker can easily apply force. Therefore, even if the coating layer W2 is thick or hard (particularly in winter, the coating layer W2 tends to be harder than in summer), the worker does not have to bear an excessive workload. In addition, the worker can quickly perform the peeling work.

In addition, when the base end structure of the peeler 1A and the peeler 1A are equipped with both the one-way clutch mechanism M and the flange 40, the operator can easily transmit force to the first operating unit 20 in the first rotation direction R1 and also in the first direction DR1. In this case, the width of the peeled coating layer (i.e., the coating layer peeled off from the core wire) obtained by rotating the first operating unit 20 in the first rotation direction R1 can be increased, and the peeling operation can be performed even more quickly.

In the example shown in FIG. 6, the one-way clutch mechanism M1 is a ratchet type (in other words, a step type) one-way clutch mechanism. In this case, it is difficult to finely adjust the position of the first operating part 20 (particularly the position adjustment by performing the above-mentioned second step ST2, in other words, the position adjustment when returning the rotation angle position of the first operating part 20 to a position where the operator can easily apply force). In contrast, in the example shown in FIG. 7 to FIG. 9, the one-way clutch mechanism M1 is a stepless one-way clutch mechanism. In this case, it is possible to finely adjust the position of the first operating part 20 both when performing the first step ST1 and when performing the second step ST2. In addition, when the one-way clutch mechanism M1 is a stepless one-way clutch mechanism, no unnecessary clicking sounds are generated during the peeling work, so the operator can concentrate on the work.

In the example shown in FIG. 1, the one-way clutch mechanism M is disposed inside the first operating unit 20. In this case, the overall size of the peeler 1A can be made more compact than when the one-way clutch mechanism M is disposed outside the first operating unit 20. In addition, when the one-way clutch mechanism M is disposed inside the first operating unit 20, the force transmission path when force is transmitted from the first operating unit 20 to the inner member 51 via the outer member 56 can be shortened. As a result, the force transmission mechanism can be made simple and highly reliable.

In addition, when the one-way clutch mechanism M is disposed inside the first operating unit 20, the overall center of gravity of the peeler 1A is closer to the first operating unit 20 than when the one-way clutch mechanism M is disposed outside the first operating unit 20. By having the overall center of gravity of the peeler 1A closer to the first operating unit 20, the operability of the first operating unit 20 is improved.

(Color Coating Layer CC)
In the example shown in Fig. 3, the base end structure of the peeler 1A and the peeler 1A have a metal part MP. In the example shown in Fig. 1, the housing part 70 is the metal part MP. Also, the stopper guide 14 is the metal part MP. Furthermore, the first part 21 of the first operating part 20 is also the metal part MP.

At least a portion of the surface of the metal part MP may be covered by a color coating layer CC. In the example shown in FIG. 3, the first part 21 of the first operating part 20 is covered by a color coating layer CC. The color coating layer CC is, for example, a plating layer. When at least a portion of the surface of the metal part MP is covered by a color coating layer CC, the type of the peeler 1A can be identified by the color of the color coating layer CC.

For example, assume that the inner diameter of the first hole 73h provided in the housing 70 of the first type peeler 1A is a first inner diameter, and the color of the color coating layer CC is a first color. In this case, in a peeler (second type peeler) in which the inner diameter of the first hole 73h is a second inner diameter larger than the first inner diameter, a second color different from the first color is used as the color of the color coating layer CC.

In the above example, an example has been described in which the color coating layer CC is arranged to cover at least a portion of the surface of the first portion 21 of the first operating unit 20. Alternatively, or in addition, the color coating layer CC may be arranged to cover at least a portion of the surface of the housing portion 70. Alternatively, or in addition, the color coating layer CC may be arranged to cover at least a portion of the surface of the stopper guide 14.

(First Operation Unit 20)
An example of the first operation unit 20 will be described with reference to FIGS.

In the example shown in FIG. 10, the first operating unit 20 has a non-metallic part 22. The non-metallic part 22 is formed, for example, from resin or rubber. In the example shown in FIG. 10, the non-metallic part 22 constitutes at least a portion of the side surface 20s of the first operating unit 20 and at least a portion of the base end surface 20e of the first operating unit 20 (more preferably, the entire base end surface 20e of the first operating unit 20).

It is assumed that at least a portion of the side surface 20s of the first operating unit 20 is a non-metallic portion 22 (a resin portion or a rubber portion), and that the first operating unit 20 is held in the right hand so that a ring is formed between the thumb and index finger. In this case, at least one of the index finger, middle finger, and ring finger comes into contact with the non-metallic portion 22. This improves the grip characteristics of the first operating unit 20.

In the example shown in FIG. 10, the side surface 20s of the first operating unit 20 includes a first portion 21 that is a metal portion MP, and a non-metal portion 22 that is disposed on the proximal side of the first portion 21. In this case, when the first operating unit 20 is held in the right hand so that a ring is formed between the thumb and index finger, the index finger comes into contact with the metal portion MP, and the middle finger and ring finger come into contact with the non-metal portion 22.

Next, assume that at least a portion of the base end surface 20e of the first operating unit 20 is a non-metallic portion 22 (a resin portion or a rubber portion), and that the first operating unit 20 is held in the right hand with the palm of the hand in contact with the base end surface 20e and the fingertips facing the first direction DR1. In this case, the palm of the hand comes into contact with the non-metallic portion 22. This improves the grip characteristics of the first operating unit 20.

As described above, when at least a portion of the side surface 20s of the first operating unit 20 is made of a non-metallic material, and at least a portion of the base end surface 20e of the first operating unit 20 is made of a non-metallic material, the first operating unit 20 has favorable grip characteristics regardless of how the first operating unit 20 is gripped (in other words, regardless of the position of the operator).

In the example shown in FIG. 10, the base end surface 20e of the first operating unit 20 is a flat surface Fs. When the entire base end surface 20e or a large portion of the base end surface 20e is a flat surface Fs, it is possible to suitably bring the palm of the hand into contact with the base end surface 20e. Alternatively, the base end surface 20e may be a curved surface (e.g., a substantially hemispherical surface) that is convex toward the second direction DR2. In this case, when the first operating unit 20 is gripped, the base end surface 20e (the curved surface that is convex toward the second direction DR2) can be suitably wrapped by the palm of the hand.

In the example shown in FIG. 10, the first side surface 20s-1 on the most proximal side of the first operating unit 20 is an inclined surface that inclines away from the longitudinal central axis CL of the peeler 1A as it moves in the first direction DR1, and the second side surface 20s-2 arranged on the first direction DR1 side from the first side surface 20s-1 is an inclined surface that inclines toward the longitudinal central axis CL of the peeler 1A as it moves in the first direction DR1. In this case, when the first operating unit 20 is held in the right hand with the palm of the hand in contact with the proximal end surface 20e and the fingertips facing the first direction DR1, the inside of the hand is easily adapted to the shape of the first side surface 20s-1 and the second side surface 20s-2. In the example shown in FIG. 10, in addition to the proximal end surface 20e, the first side surface 20s-1 and the second side surface 20s-2 are made of non-metal (for example, made of resin or rubber). This improves the grip characteristics of the first operating unit 20. Note that the first side surface 20s-1 and the second side surface 20s-2 are each annular.

In the example shown in FIG. 10, the third side surface 20s-3, which is located closer to the first direction DR1 than the second side surface 20s-2, is an inclined surface that slopes closer to the longitudinal central axis CL of the peeler 1A as it approaches the first direction DR1. The third side surface 20s-3 is an annular side surface and is made of metal. Also, in the example shown in FIG. 10, the flange portion 40 described above is located closer to the first direction DR1 than the third side surface 20s-3.

As illustrated in FIG. 11, the non-metallic part 22 may be configured as a bottomed tubular member (in other words, a cap member). In this case, the metallic first part 21 can be easily disposed inside the non-metallic part 22. The non-metallic part 22 and the metallic first part 21 are joined by any fastening means.

As illustrated in FIG. 11, at least one recess 200 (a portion recessed from the circumferential surface) may be formed on the first side surface 20s-1 or the second side surface 20s-2. Preferably, N recesses 200 (where "N" is a natural number equal to or greater than "2," "3," "4," or "5") are formed at equal intervals around the longitudinal center axis CL of the peeler 1A. As illustrated in FIG. 11, each recess 200 may be disposed so as to straddle both the first side surface 20s-1 and the second side surface 20s-2.

The presence of the recess 200 improves the grip characteristics of the first operating part 20.

In the example shown in FIG. 12, the outer member 56 of the one-way clutch mechanism M is supported (more specifically, fixed) to the first operating unit 20. Alternatively, the outer member 56 may be formed integrally with the first operating unit 20.

When the outer member 56 of the one-way clutch mechanism M is supported (more specifically, fixed) to the first operating part 20 or is formed integrally with the first operating part 20, the one-way clutch mechanism M can be easily assembled, disassembled, or replaced.

In the example shown in FIG. 12, the one-way clutch mechanism M is assembled as follows:

First, the outer member 56 of the one-way clutch mechanism M is moved relative to the inner member 51 in the first direction DR1 together with the first operating unit 20 (see arrow F). Thus, the outer member 56 and the first operating unit 20 are arranged to cover the inner member 51. Secondly, the first operating unit 20 (or the outer member 56) is fixed to the stopper guide 14 (or the inner member 51) via a fixing member 59 such as a fixing screw so as to be rotatable relative to the inner member 51 and the stopper guide 14. Thus, the outer member 56 is supported by the inner member 51 so as to be rotatable in one direction (i.e., the first rotation direction R1) relative to the inner member 51. Note that after being fixed by the fixing member 59, it is preferable that the outer member 56 cannot move relative to the inner member 51 in a direction parallel to the first direction DR1. In the example shown in FIG. 12, the fixing member 59 can move along the annular groove 145 formed in the stopper guide 14, but cannot move relative to the stopper guide 14 in a direction parallel to the first direction DR1.

Disassembly of the one-way clutch mechanism M is carried out in the reverse order of assembly of the one-way clutch mechanism M.

First, the fixed member 59 is removed. Thus, the outer member 56 (and the first operating unit 20) becomes movable relative to the inner member 51 (and the stopper guide 14) in a direction parallel to the first direction DR1. Second, the outer member 56, together with the first operating unit 20, is moved relative to the inner member 51 in the second direction DR2. Thus, the outer member 56 and the first operating unit 20 are removed from the inner member 51.

Second Embodiment
The base end structure of the peeler 1B and the peeler 1B in the second embodiment will be described with reference to Fig. 13. Fig. 13 is a schematic vertical cross-sectional view showing the peeler 1B in the second embodiment.

In the second embodiment, the differences from the first embodiment will be mainly described, and repetitive descriptions of matters already described in the first embodiment will be omitted. Therefore, it goes without saying that matters already described in the first embodiment can be adopted in the second embodiment even if they are not explicitly described in the second embodiment.

The peeler 1B in the second embodiment differs from the peeler 1A in the first embodiment in that the base end structure (the structure of the base end PP) of the peeler 1B and the tip end structure (the structure of the tip end DP) of the peeler 1B are separable from each other. In other respects, the peeler 1B in the second embodiment is similar to the peeler 1A in the first embodiment.

In the example shown in FIG. 13, the housing part 70 to which the peeler blade part 72 is attached and the stopper guide 14 are separate members. In addition, the stopper guide 14, which constitutes at least a part of the base end structure of the peeler 1B, is attached to the housing part 70, which constitutes at least a part of the tip end structure of the peeler 1B. More specifically, the housing part 70 and the stopper guide 14 are fixed via a fixing member 78 such as a fixing screw.

In the example shown in FIG. 13, the housing part 70 and the stopper guide 14 are separable from each other. In this case, any type of housing part 70 can be combined with any type of stopper guide 14 to assemble any peeler 1B. Also, if either the housing part 70 or the stopper guide 14 is damaged, only the damaged part needs to be replaced.

In the example shown in FIG. 13, the first operating unit 20 and the stopper guide 14 are separable from each other. In this case, any type of first operating unit 20 can be combined with any type of stopper guide 14 to assemble any peeler 1B. Also, if either the first operating unit 20 or the stopper guide 14 is damaged, only the damaged part needs to be replaced.

The second embodiment has the same effects as the first embodiment.

(Other detailed configurations of the peeler 1)
Other configurations that can be adopted in the peeler 1 of the embodiment will be described with reference to Fig. 14. Fig. 14 is a schematic two-sided view showing the peeler 1 of the embodiment. The upper side of Fig. 14 shows a schematic vertical cross-sectional view, and the lower side of Fig. 14 shows a schematic plan view.

In the example shown in FIG. 14, the peeler 1 includes a housing portion 70 to which the peeler blade portion 72 is attached, a first operating portion 20, and a stopper guide 14 having one end connected to the housing portion 70 and the other end connected to the first operating portion 20.

The housing portion 70 has a storage portion capable of storing the end of the object to be peeled W. More specifically, the storage portion is constituted by a first hole portion 73h formed in the housing portion 70.

In the example shown in FIG. 14, the housing portion 70 includes a bulge portion 71 that protrudes radially outward beyond the stopper guide 14. The peeler blade portion 72 is attached to the bulge portion 71.

The peeler blade portion 72 has a first blade 72a (i.e., a stripping blade) that strips the coating layer W2 from the core wire W1, and a second blade 72b (i.e., a chamfering blade) that forms a chamfered portion WC (see FIG. 2, if necessary) in the coating layer W2. Each of the first blade 72a and the second blade 72b is attached to the housing portion 70 via any fixing member. Each of the first blade 72a and the second blade 72b is attached to the housing portion 70 so as to be replaceable.

In the example shown in FIG. 14, at least a portion of the bottom surface 70b of the housing portion 70 (in other words, the surface opposite to the side where the peeler blade portion 72 is arranged) is a flat surface. Since at least a portion of the bottom surface 70b is a flat surface, the peeler 1 will not roll when placed on a support surface such as a table or shelf. In the example shown in FIG. 14, the flat surface constituting at least a portion of the bottom surface 70b of the housing portion 70 is provided on the bulge portion 71.

A first opening OP1 is formed at the end of the housing part 70 on the first direction DR1 side, and the first opening OP1 communicates with a first hole part 73h formed in the housing part 70. The first hole part 73h extends along the longitudinal center axis CL of the peeler 1.

A second opening OP2 is formed on the side of the housing portion 70. The coating layer W2 peeled off by the peeler blade portion 72 is discharged from the second opening OP2. The peeler blade portion 72 is positioned so that at least a portion of the cutting edge protrudes into the second opening OP2.

A connecting hole 74h is disposed between the housing 70 and the stopper guide 14. The connecting hole 74h is a hole that connects the first hole 73h provided in the housing 70 and the second hole 14h provided in the stopper guide 14. It is preferable that the wall surface that defines the connecting hole 74h is an inclined surface that inclines in a direction approaching the longitudinal center axis CL of the peeler 1 as it approaches the second direction DR2.

The core wire W1 from which the coating layer W2 has been stripped is inserted into the second hole 14h. The inner diameter of the second hole 14h is smaller than the inner diameter of the first hole 73h. The stopper 12 is arranged in the second hole 14h so that its position can be freely adjusted in the direction along the first direction DR1.

The stopper 12 may have a threaded hole 12h that screws into a threaded portion formed in the connecting portion 15. In the example shown in FIG. 14, the second operating portion 16 is rotated around the central axis of the connecting portion 15, causing the connecting portion 15 to advance within the threaded hole 12h. Then, the distance between the stopper 12 and the second operating portion 16 becomes smaller, and the stopper 12 and the second operating portion 16 are fixed to the stopper guide 14.

In the example shown in FIG. 14, the second operating unit 16 is disposed on the opposite side to the bottom surface 70b of the housing part 70 (in other words, on the upper side). Therefore, when the peeler 1 is placed on a support surface such as a table or shelf so that the bottom surface 70b contacts the support surface, there is no interference between the second operating unit 16 and the support surface. Therefore, when the peeler 1 is placed on the support surface, the position of the second operating unit 16 does not shift.

The second operating part 16 is disposed in a recess 140 defined by the end face 70e of the housing part 70 on the second direction DR2 side, the end face 20f of the first operating part 20 on the first direction DR1 side, and the outer peripheral surface 14a of the stopper guide 14 in a vertical section passing through the longitudinal center axis CL of the peeler 1. The distance L2 between the end face 70e and the end face 20f is, for example, 3 cm to 15 cm, 4 cm to 9 cm, or 5 cm to 7 cm. It goes without saying that the invention described in the claims is not limited by the numerical example and other numerical examples in this specification. In other words, numerical values outside the numerical ranges described in this specification may be used in the embodiment.

In the example shown in FIG. 14, the end surface 20f is formed by the first surface 40b of the flange portion 40. The diameter of the flange portion 40 is, for example, 3 cm or more and 5 cm or less.

In the example shown in FIG. 14, the inner member 51 is fixed to the end of the stopper guide 14 on the second direction DR2 side. As illustrated in FIG. 14, the end of the inner member 51 on the first direction DR1 side may be inserted into the end of the stopper guide 14 on the second direction DR2 side.

An outer member 56 is disposed outside the inner member 51. The inner member 51 and the outer member 56 form a one-way clutch mechanism M.

In the example shown in FIG. 14, the first operating unit 20 (more specifically, the first portion 21) is arranged to cover the outer member 56. It is preferable that the outer member 56 is fixed to the first operating unit 20.

In the example shown in FIG. 14, the first operating unit 20 excluding the end portion on the first direction DR1 side (i.e., the flange portion 40) and the end portion on the second direction DR2 side, i.e., the central portion of the first operating unit 20, has a tapered shape whose diameter decreases toward the first direction DR1. It is preferable that the central portion of the first operating unit 20 has an approximately truncated cone shape.

The maximum diameter L3 of the first operating part 20 excluding the flange 40 is, for example, 3 cm or more and 5 cm or less. The maximum diameter L3 is approximately equal to the diameter of the flange 40.

The minimum diameter L4 of the first operating part 20 is 2 cm or more and 4 cm or less. The length of (maximum diameter L3 - minimum diameter L4) is, for example, 0.5 cm or more and 3 cm or less, or 1 cm or more and 2 cm or less. The part corresponding to the minimum diameter L4 is located near the flange part 40 (for example, within 1 cm or within 5 mm from the pressed surface 40a of the flange part 40).

The distance L5 from the end face 20f of the first operating unit 20 on the first direction DR1 side to the end face (20e) of the first operating unit 20 on the second direction DR2 side is, for example, 4 cm or more and 9 cm or less, or 5 cm or more and 7 cm or less.

In the example shown in FIG. 14, a stopper guide 14 is disposed between the housing part 70 to which the peeler blade part 72 is attached and the first operating part 20. Therefore, the hand of the operator holding the first operating part 20 does not interfere with the second opening OP2 through which the peeled coating layer W2 is discharged.

The present invention is not limited to the above-described embodiments, and it is clear that each embodiment can be modified or changed as appropriate within the scope of the technical concept of the present invention. In addition, the various techniques used in each embodiment can be applied to other embodiments as well, so long as no technical contradiction arises. Furthermore, any additional configurations in each embodiment can be omitted as appropriate.

For example, in the examples shown in Figures 1 to 14, the one-way clutch mechanism M is provided in the base end structure of the peeler. Alternatively, at least a portion of the one-way clutch mechanism M may be provided in the tip end structure of the peeler.

In the examples shown in Figs. 1 to 14, the peeler 1 is a hand tool driven by the force of an operator. Alternatively, or additionally, the peeler 1 in the embodiment may be driven by an external power source such as a power tool. As shown in Fig. 15, the base end of the peeler 1 may be formed with an engagement portion 90 (e.g., an engagement hole portion having a cross-sectional shape of a regular polygon) that can engage with a rotating member of the power tool.

When the peeler of the present invention is used, the stopper that positions the end of the core wire of the object to be peeled is prevented from moving unintentionally. In addition, the peeling operation can be easily performed by rotating the first operating part back and forth. As a result, the burden on the worker who uses the peeler is reduced, and no skill is required for the peeling operation. Therefore, the present invention is useful for businesses that use peelers and manufacturers that manufacture peelers.
