Description

Technical Field

[0001] The present invention relates to a tool, a tool set, and a member removal method.

Background Art

[0002] For fixing a wire harness to a vehicle body, a clip for attaching a wire harness has been proposed (see, for example, Patent Document 1). The clip has a fixing portion. The fixing portion is provided on the surface of the base portion and has a leg portion and a pair of elastic locking claws. The leg portion protrudes linearly. The pair of elastic locking claws are provided at the tip of the leg portion. The pair of elastic locking claws are tapered so as to gradually widen toward the base of the leg portion.

[0003] The fixing portion is inserted into a locking hole provided in the vehicle body. When the fixing portion is inserted into the locking hole, the pair of elastic locking claws are elastically deformed so as to approach each other by the inner peripheral surface of the locking hole. Then, when the pair of elastic locking claws pass through the locking hole, they are elastically deformed so as to separate from each other, the pair of elastic locking claws expand outward, and the tips of the pair of elastic locking claws are positioned outside the locking hole. As a result, in the thickness direction of the vehicle body, the vehicle body is sandwiched between the tips of the pair of elastic locking claws and the surface of the base portion, and the wire harness and the clip are in a fixed state fixed to the vehicle body.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when the wire harness is fixed to the vehicle body with the above clip, the wire harness is located on the surface of the vehicle body, and the fixing portion of the clip is located on the back surface of the vehicle body. Usually, there is often not enough space on the back surface side of the vehicle body, so it is often difficult to put a hand or tool into the space on the back surface side of the vehicle body to release the fixed state of the fixing portion. In this case, when removing the wire harness from the vehicle body, a minus driver or a dedicated L-shaped tool with a bent tip forming an L-shape is inserted from the space on the surface side of the vehicle body between the vehicle body and the base portion, and without releasing the fixed state of the fixing portion, the fixing portion is forcibly pulled out by the principle of leverage, and the wire harness is removed from the vehicle body. For this reason, when pulling out the fixing portion, the fixing portion was often damaged.

[0006] In view of such circumstances, the present invention aims to provide a tool, a tool set, and a member removal method that can easily release the fixed state of the fixing portion of a member and remove the member.

Means for Solving the Problems

[0007] The tool of the present invention is a tool for removing a member having a member main body portion and a fixing portion that is connected to the member main body portion and, when inserted into a hole in the body of an object, deforms by the pressing force from the hole so that the width of the deformed portion in the radial direction of the hole decreases, and after passing through the hole, expands outward in the radial direction of the hole so that the width of the deformed portion increases and locks to the body on the back surface of the body to fix the member main body portion on the surface side of the body, and includes a passage through which the fixing portion can be inserted through an inlet opening on one end side, and an end surface including the inlet opening. The inlet opening has at least a pair of fixing portion contact regions that contact the fixing portion in the middle of the height direction of the fixing portion when the fixing portion is inserted into the passage. The end surface has a back surface contact region that contacts the back surface when moving while shrinking the fixing portion inward in the radial direction of the hole by the pressing force from the pair of fixing portion contact regions and reaching the back surface of the body. In a state where the fixing portion is inserted into the passage, the pair of fixing portion contact regions are characterized by contacting and overlapping the edge of the hole or being located inside the hole in the radial direction from the edge of the hole.

[0008] In the tool of the present invention, it has a cylindrical body with at least one end open, and the passage is formed by the inner peripheral surface of the cylindrical body.

[0009] In the tool of the present invention, the back surface contact area includes the fixing part contact area.

[0010] In the tool of the present invention, the fixing part contact area and the back surface contact area contact and overlap with an annular area around the hole including the edge of the hole on the back surface of the body.

[0011] In the tool of the present invention, the length along the passage direction of the passage is shorter than the length of the protruding part of the fixing part protruding in the height direction of the fixing part starting from the back surface of the body in the fixed state of the fixing part.

[0012] The tool set of the present invention includes a plurality of the tools, and those having different inner peripheral side shapes of the cross section cut in a direction perpendicular to the central axis of the passage are included. The inner peripheral side shape of the cross section includes at least two of a circle, an ellipse, a square, a rectangle, and a rounded rectangle.

[0013] The method for removing a member of the present invention includes a member main body portion, and a fixing portion that is connected to the member main body portion and is deformed by pressing from the hole when inserted into a hole in the body of an object, so that the width of the deformed portion in the radial direction of the hole decreases, and after passing through the hole, it expands outward in the radial direction of the hole and the width of the deformed portion increases while being locked to the body on the back surface of the body, and the member main body portion is fixed on the surface side of the body. A method for removing a member from the body, the method comprising: a fixing release step of mounting the tool on the fixing portion so that the fixing portion is inserted into a passage of the tool having a passage into which the fixing portion can be inserted, pushing the tool toward the back surface of the body, and pressing the fixing portion inward in the radial direction of the hole by a surface forming the passage of the tool to reduce the width of the deformed portion of the fixing portion to a size that can pass through the hole, thereby releasing the fixed state of the fixing portion; and a member removal step of pulling out the fixing portion together with the member main body portion from the surface side of the body after the fixed state of the fixing portion is released, thereby removing the member from the body.

[0014] In the method for removing a member of the present invention, the tool is formed in a cylindrical shape, and the passage is constituted by the inner peripheral surface of the tool.

Advantages of the Invention

[0015] According to the tool, tool set, and method for removing a member of the present invention, the fixed state of the fixing portion of the member can be easily released and the member can be removed. In particular, it is effective when the fixing portion is located at a position where there is not enough space in the vehicle body.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The accompanying drawings are an example of the embodiments for carrying out the invention, and in the figures, parts denoted by the same reference numerals represent the same objects. Also, the shapes and dimensional ratios of each part in each figure are not necessarily accurate.

[0018] <Overall Configuration> The member 1 and the tool 2 in the embodiment of the present invention will be described below. The member 1 is attached to the body 110 of the object 100 (for example, a vehicle).

[0019] <Member> Specifically, as shown in FIGS. 1(A) and 2(A), the member 1 has a member main body portion 10 and a fixing portion 11. The member main body portion 10 may be, for example, a housing for mounting components, but is not limited thereto, and may include all other members.

[0020] <Fixing Portion> As shown in FIG. 1(A), the fixing portion 11 is connected to the member main body portion 10, and as shown in FIGS. 3(A) to 3(D), fixes the member main body portion 10 to the body 110 of the object 100. Specifically, the fixing portion 11 has, for example, a fixing main body portion 12 and a pair of claw portions 13.

[0021] <Fixing Main Body Portion> The fixing main body portion 12 is connected to the member main body portion 10. As shown in FIGS. 1(A) and 2(A), the fixing main body portion 12 has a shaft portion 12A, a base portion 12B, and a pair of front-side locking pieces 12C. The shaft portion 12A may be formed in a shaft rod shape as shown in FIG. 1(A), or may be formed by connecting a shaft rod and a box-shaped box portion 12A1 as shown in FIG. 2(A).

[0022] The base portion 12B serves as the base of the fixing main body portion 12, and is formed in a plate shape in the present embodiment, but is not limited thereto, and may have other shapes. The shaft portion 12A is connected to the base portion 12B and extends starting from the center of the surface of the base portion 12B.

[0023] The pair of front-side locking pieces 12C extend on the same side as the shaft portion 12A starting from the end of the surface of the base portion 12B or a position offset from the center, while inclining with respect to the shaft portion 12A such that the distal side from the base portion 12B is more distal from the shaft portion 12A than the proximal side. In other words, each of the pair of front-side locking pieces 12C extends while inclining in the obliquely outer upper direction starting from the portion continuous with the base portion 12B. And the pair of front-side locking pieces 12C may have at least one set, or may have a plurality of sets.

[0024] As shown in FIGS. 1(A) and 2(A), each of the pair of claw portions 13 is connected to the fixed main body portion 12 at the tip of the fixed main body portion 12 or above the center in the height direction H of the fixed main body portion 12. Each of the pair of claw portions 13 is located on the opposite side of each other with respect to the fixed main body portion 12. That is, each of the pair of claw portions 13 is located at a position where the relative phase difference between the pair of claw portions 13 is 180 degrees with respect to the circumferential direction of the fixed main body portion 12. And each of the pair of claw portions 13 has an inclined piece 13A and a stopper piece 13B.

[0025] One end of the inclined piece 13A is connected to the shaft portion 12A and becomes a fixed end with respect to the shaft portion 12A. On the other hand, the other end of the inclined piece 13A is connected to the stopper piece 13B and becomes a free end with respect to the shaft portion 12A. And the stopper piece 13B, for example, may be one that extends parallel to the shaft portion 12A as an example, but is not limited to this, and may extend in other directions.

[0026] Here, the direction along the central axis 120 of the fixed main body portion 12 (hereinafter referred to as the fixed main body central axis) is defined as the height direction H, and the direction orthogonal to the fixed main body central axis 120 is defined as the orthogonal direction V. Each of the pair of inclined pieces 13A is inclined such that, with respect to the height direction H of the fixed main body portion 12 as a reference, the distal portion from the top 122 of the fixed main body portion 12 is located on the distal side (outside the orthogonal direction V) with respect to the proximal portion from the top 122 of the fixed main body portion 12 in the orthogonal direction V. That is, each of the pair of inclined pieces 13A is inclined with respect to the fixed main body portion 12 so as to extend in the combined direction of the direction from the top 122 side to the base 12B side of the fixed main body portion 12 in the height direction H and the direction away from the fixed main body portion 12 in the orthogonal direction V, starting from the portion continuous with the fixed main body portion 12. In other words, each of the pair of inclined pieces 13A starts from the portion continuous with the fixed main body portion 12 and extends while inclining obliquely downward and outward. And let the inclination angle of each of the pair of inclined pieces 13A with respect to the fixed main body central axis 120 in the initial state where no external force is applied to each of the pair of claw portions 13 be α.

[0027] As shown in FIGS. 1(A) and 2(A), when a pressing force toward the fixed main body central axis 120 on the side (inner side) in the orthogonal direction V is applied to each of the pair of claw portions 13, each of the pair of claw portions 13 swings toward the fixed main body central axis 120 with the portion continuous with the fixed main body portion 12 as a swing axis, and the inclination angle of the inclined piece 13A with respect to the fixed main body central axis 120 decreases to β (α>β). As a result, the maximum width W of the fixed portion 11 in the orthogonal direction V in the deformed portion (hereinafter referred to as the fixed portion deformation region) that deforms by swinging in the fixing portion 11 max decreases. Note that the fixed portion deformation region refers to the region (portion) of the fixed portion 11 that includes the pair of claw portions 13.

[0028] Then, when the above-mentioned pressing force applied to the claw portion 13 disappears, the claw portion 13 swings in the direction away from the fixed main body central axis 120 with the portion continuous with the fixed main body portion 12 as a swing axis by the elastic force, and returns to the posture such that the inclination angle of the inclined piece 13A with respect to the fixed main body central axis 120 becomes α. As a result, the maximum width W of the fixed portion 11 in the orthogonal direction V in the fixed portion deformation region max increases.

[0029] Note that at least one pair of claw portions 13 is sufficient, and there may be a plurality of pairs. Also, an odd number of claw portions 13 may be provided. In this case, it is preferable that the claw portions 13 are positioned such that the phase difference between adjacent claw portions 13 (for example, if there are three claw portions 13, the phase difference between adjacent claw portions 13 is 120 degrees) is the same with reference to the circumferential direction of the fixed main body portion 12.

[0030] <Attachment of Components to the Body> With reference to FIG. 3, a method of attaching the member 1 to the body 110 will be described. As shown in FIG. 3(A), on the surface side of the body 110, the fixing portion 11 of the member 1 is inserted from the top portion 122 into the hole 112 of the body 110. Note that the top portion 122 of the fixing portion 11 has a size that can pass through the hole 112.

[0031] As shown in FIG. 3(B), when the fixing portion 11 is pushed into the depth of the hole 112, a partial region of the claw portion 13 (inclined piece 13A) following the top portion 122 passes through the hole 112, and the claw portion 13 (inclined piece 13A) contacts the hole edge 112A of the hole 112 on the surface side of the body 110 at an intermediate position of the claw portion 13 (inclined piece 13A). When the pushing of the fixing portion 11 is continued, as shown in FIG. 3(C), due to the pressing from the hole edge 112A or the hole 112, the claw portion 13 swings, and the inclination angle of the inclined piece 13A with reference to the fixed main body central axis 120 gradually decreases. In other words, the fixing portion 11 is deformed by the pressing from the hole edge 112A or the hole 112, and the width (maximum width) of the fixing portion deformation region of the fixing portion 11 in the radial direction of the hole 112 gradually decreases.

[0032] When the inclined piece 13A passes through the hole 112, as shown in FIG. 3(D), since the pressing from the hole 112 against the inclined piece 13A disappears, the inclined piece 13A and the stopper piece 13B swing so as to expand outward in the orthogonal direction V, and the inclination angle of the inclined piece 13A with reference to the fixed main body central axis 120 increases. In other words, the width (maximum width) of the fixing portion deformation region of the fixing portion 11 in the radial direction of the hole 112 increases.

[0033] At this time, the lower end surface 13C of the inclined piece 13A in the height direction H engages with the peripheral region of the hole 112 on the back surface 114 of the body 110. Further, the stopper piece 13B engages with the surface forming the hole 112. On the other hand, the front-side locking piece 12C engages with the front surface 116 of the body 110 at its tip 12D. As a result, the body 110 is clamped by both the front-side locking piece 12C and the claw portion 13. Thereby, the fixing portion 11 is fixed to the body 110, and the member main body portion 10 is fixed to the body 110 on the front surface 116 side of the body 110.

[0034] As described above, the member main body portion 10 is fixedly attached to the body 110 without play on the front surface 116 side of the body 110, but the member main body portion 10 may be fixed with play.

[0035] <Tool> With reference to FIG. 4, the tool 2 will be described. As shown in FIGS. 4(A) and 4(B), the tool 2 has a passage 20 into which the fixing portion 11 can be inserted and an end surface 25 connected to one end of the passage 20. The passage 20 has an entrance opening 21 for inserting the fixing portion 11 into the passage 20.

[0036] As shown in FIG. 4(C), the entrance opening 21 has a size through which the top of the fixing portion 11 (the top 122 in the height direction of the fixing main body portion 12) can pass. Further, as shown in FIGS. 4(C) and 4(D), when the tool 2 is attached to the fixing portion 11 so that the fixing portion 11 is inserted into the passage 20, the entrance opening 21 has a pair of fixing portion contact regions 210 that contact the claw portion 13 (inclined piece 13A) of the fixing portion 11 in the middle of the height direction H of the fixing portion 11. Note that the number of the fixing portion contact regions 210 corresponds to the number of the inclined pieces 13A. Therefore, as the number of the inclined pieces 13A increases, the number of the fixing portion contact regions 210 increases accordingly.

[0037] The end surface 25 is an annular surface including the entrance opening 21 and expands starting from the entrance opening 21. The end surface 25 has a back surface contact region 212 that contacts the back surface 114 when it reaches the back surface 114 of the body 110. This will be described later.

[0038] In addition, in this embodiment, although the side opposite to the inlet opening 21 of the passage 20 in the passage direction of the passage 20 is open, it is not limited thereto and may be closed.

[0039] In this embodiment, the tool 2 is composed of a cylindrical body 22 formed in a cylindrical shape. The inner peripheral surface 22A of the cylindrical body 22 constitutes the passage 20. The opening on one end side in the axial direction of the cylindrical body 22 constitutes the inlet opening 21. And, the surface on one end side in the axial direction of the cylindrical body 22 constitutes the end face 25. The cylindrical body 22 in this embodiment has an open other end side, but it may be closed.

[0040] <Removal of the component from the body> With reference to FIG. 5, a method for removing the member 1 from the body 110 by the cylindrical body 22 as the tool 2 will be described. The member removal method includes a fixing release step and a member removal step.

[0041] <Fixing release step> The fixing release step is a step of releasing the fixed state of the fixing portion 11. Specifically, in the fixing release step, first, as shown in FIGS. 5(A) and 5(B), the cylindrical body 22 is attached to the fixing portion 11 so that the fixing portion 11 is inserted into the passage 20 of the cylindrical body 22, and the cylindrical body 22 is pushed toward the back surface 114 of the body 110. At this time, as shown in FIG. 5(B), in the middle of the height direction H of the fixing portion 11, a pair of fixing portion contact regions 210 of the inlet opening 21 of the cylindrical body 22 come into contact with the inclined piece 13A of the fixing portion 11.

[0042] When the pushing of the cylindrical body 22 continues further, the fixing portion 11 (claw portion 13) functions as a guide, and the cylindrical body 22 is guided in the direction along the height direction H by the fixing portion 11 (claw portion 13) and approaches the back surface 114 of the body 110. While the cylindrical body 22 approaches the back surface 114 of the body 110, as shown in FIG. 5(C), the claw portion 13 (inclined piece 13A) is pressed by the pair of fixing portion contact regions 210, swings about the swing axis toward the fixing body central axis 120, and the inclination angle of the inclined piece 13A with respect to the fixing body central axis 120 gradually decreases. Then, when the back surface contact region 212 of the end surface 25 constituting the entrance opening 21 side in the axial direction of the cylindrical body 22 contacts the back surface 114 of the body 110, the maximum width of the fixing portion deformation region of the fixing portion 11 shrinks to a size that can pass through the hole 112. As a result, the fixed state of the fixing portion 11 is released.

[0043] Also, as shown in FIGS. 5(A) to 5(C), it is preferable that the length D of the tool 2 in the passage direction T of the passage 20 is shorter than the length L of the protruding portion of the fixing portion 11 (claw portion 13) protruding in the height direction H starting from the back surface 114 of the body 110 in the fixed state of the fixing portion 11. This is because even if the claw portion 13 is located at a position where there is not enough space, making the tool 2 compact makes it easier to attach the tool 2 to the fixing portion 11 (claw portion 13).

[0044] <Mode of releasing the fixed state of the fixing portion> In order for the fixed state of the fixing portion 11 to be released, it is sufficient that the maximum width of the fixing portion deformation region becomes equal to or less than the diameter of the hole 112 due to the pressing of the fixing portion contact region 210 before the back surface contact region 212 of the end surface 25 contacts the back surface 114 of the body 110. There are a plurality of embodiments of the tool 2 that can achieve the above.

[0045] For example, when the shape of the hole edge 112A of the hole 112 is circular, it is preferable that the shape of the inlet opening 21 of the cylindrical body 22 is also circular with the same diameter as the hole edge 112A. In this case, when the cylindrical body 22 is mounted on the fixing portion 11 and the fixing state is released (see Fig. 6(A)) and viewed in plan from the height direction H (see Fig. 6(B)), the end face 25 of the cylindrical body 22 does not overlap with the area surrounded by the hole 112 (hole edge 112A), and the entire area of the end face 25 overlaps with the surrounding annular area 117 that is continuous with the opening of the hole 112 on the back surface 114 of the body 110.

[0046] And, as shown in Fig. 6(A), the entire area of the end face 25 may become the back surface contact area 212 and contact the annular area 117, or as shown in Fig. 6(C), a partial area of the end face 25 (for example, the entire circumference of the inlet opening 21) may become the back surface contact area 212 and contact the annular area 117. However, when a partial area of the end face 25 becomes the back surface contact area 212, the inlet opening 21 needs to be included in a partial area of the end face 25. If the inlet opening 21 is not included in the back surface contact area 212 of the end face 25, as shown in Fig. 6(D), the claw portion 13 will spread outside the hole edge 112A, and the fixing state of the fixing portion 11 cannot be released.

[0047] Also, even when the shape of the hole edge 112A of the hole 112 is circular, when viewed in plan as described above, as shown in Figs. 7(A) and 7(B), the cylindrical body 22 may have a hole overlapping area 220 where the end face 25 of the cylindrical body 22 overlaps with the area surrounded by the hole 112 (hole edge 112A), and a back surface overlapping area 230 where the end face 25 of the cylindrical body 22 overlaps with the back surface 114. Each of the hole overlapping area 220 and the back surface overlapping area 230 has a pair, with the fixing portion 11 intervening therebetween. It can also be said that the fixing portion contact area 210 is located on the inner side in the radial direction of the hole 112 rather than the edge 112A of the hole 112.

[0048] In the aspect shown in FIG. 7(A), in a plan view, the fixed portion contact region 210 overlaps with the hole edge 112A, and the width of the fixed portion deformation region of the fixed portion 11 is made the same as the diameter of the hole 112 by the fixed portion contact region 210 to release the fixed state. In this case, for the same reason as described above with reference to FIG. 6(D), the fixed portion contact region 210 of the inlet opening 21 needs to be included in the back surface contact region 212. That is, the fixed portion contact region 210 needs to contact the hole edge 112A as the back surface contact region 212.

[0049] In the aspect shown in FIG. 7(B), the width of the fixed portion deformation region of the fixed portion 11 is made smaller than the diameter of the hole 112 by the fixed portion contact region 210 to release the fixed state. In this case, in a plan view, as shown in FIG. 7(B), the fixed portion contact region 210 is located at a position overlapping with the hole overlapping region 220. That is, the fixed portion contact region 210 is located inside the hole 112 in the radial direction of the hole 112 rather than the edge 112A of the hole 112. In this case, the fixed portion contact region 210 is not included in the back surface contact region 212. Also, even if the inlet opening 21 is not included in the back surface contact region 212, the problems as described above with reference to FIG. 6(D) do not occur.

[0050] Also, the holes into which the fixed portion 11 shown in FIGS. 2(A) and (B) is inserted are assumed to be, for example, quadrilaterals as shown in FIGS. 8(A) to (C). In this case as well, what has been described above is applicable. Further, what has been described above is also applicable to the fixed portion 11 and holes of other shapes.

[0051] <Component removal process> In the component removal process, as shown in FIG. 5(D), after the fixed state of the fixed portion 11 is released, the fixed portion 11 together with the component main body portion 10 is pulled out from the surface side of the body 110 to remove the component 1 from the body 110.

[0052] <Tool set (tool series)> In this embodiment, examples of the shape of the fixing portion 11 include various shapes such as those shown in FIG. 1 and those having a box-shaped portion as shown in FIG. 2. For example, when the fixing portion 11 is viewed in plan, as shown on the left side of FIGS. 9(A) to (E), the shape of the box portion 12A1 of the shaft portion 12A may be rectangular, square, circular, elliptical, rounded rectangular, etc., but is not limited thereto, and other shapes may also be acceptable.

[0053] Correspondingly, it is preferable to have a tool set composed of a plurality of tools 2. Note that the tool set is an aggregate of a plurality of tools 2 and may be read as a tool series. The tool set includes a plurality of tools 2 (cylindrical bodies 22) whose inner peripheral side shapes of the cross sections cut in a direction perpendicular to the central axis (fixed main body central axis 120) of the passage of the tool 2 (cylindrical body 22) are different. And, as shown in FIGS. 9(A) to (E), examples of the inner peripheral side shape of the cross section of the cylindrical body 22 include, for example, rectangular, square, circular, elliptical, rounded rectangular, etc., but are not limited thereto, and other shapes may also be acceptable. Among the plurality of tools 2 (cylindrical bodies 22) belonging to the tool set, at least two types selected from those having rectangular, square, circular, elliptical, and rounded rectangular inner peripheral side shapes of the cross section may be included. And, a plurality of those having the same inner peripheral side shape of the cross section of the cylindrical body 22 but different sizes may also be included.

[0054] Note that as long as the fixing state of the fixing portion 11 can be released by the tool 2, the shape of the box portion 12A1 of the shaft portion 12A and the inner peripheral side shape of the cross section of the cylindrical body 22 do not have to match.
