[0003] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2007-232063 Summary of the Invention

[0004] The problem to be solved by the present invention In the technology disclosed in Patent Document 1, when the cover is closed, the movement in the closing direction of the cover is blocked by the base. Therefore, due to dimensional deviations in various parts of the retaining member, the pressing piece may not be able to fully contact the tube, and the retaining state of the tube may be unstable.

[0005] The object of the present invention is to provide a retaining member that can stably hold a long strip member.

[0006] Solution for solving the problem To address the aforementioned issues, one embodiment of the present invention provides a retaining member comprising: a main body having a pair of retaining portions for retaining an elongated member; and a cover portion connected to the main body at its base end, the cover portion being rotatable relative to the main body. The retaining portions open radially into the elongated member, allowing the elongated member to be received through the opening. The cover portion has a closed opening state and an open opening state. The cover portion includes: a locking portion provided at its top end, restricting rotation in the opening direction of the cover portion when locked to the main body; an inner surface opposing the main body portion in the closing direction of the cover portion; and a protrusion that, in the closed state, protrudes from the inner surface into the opening and abuts against the outer peripheral surface of the retained elongated member. When the protrusion abuts against the outer peripheral surface of the elongated member, a gap is formed between the inner surface and the end face of the main body portion opposing the inner surface.

[0007] Invention Effects According to the present invention, a retaining member is provided that can stably hold a long strip member. Attached Figure Description

[0012] Figure 1 This is a perspective view of the retaining structure 1 in the embodiment. Furthermore, Figure 2 This is a perspective view of the retainer 10 in the embodiment. The retaining structure 1 is composed of the retainer 10, the first elongated member 12a, and the second elongated member 12b (referred to as "elongated member 12" without distinguishing between them).

[0013] The retainer 10 can hold multiple elongated members 12. The elongated members 12 are, for example, pipes that allow fluids used in vehicles to move, and function as joints connecting the pipes to each other. Tubes for connecting other pipes extend from the sides of the elongated members 12; the shapes of the tubes on the sides differ in the first elongated member 12a and the second elongated member 12b.

[0014] Retaining component 10 can be used Figure 1 The elongated member 12 shown is used for holding, but any elongated member is acceptable, not limited to pipes; it can also be a wire harness or a rod. In this embodiment, the retainer 10 holds both elongated members 12, but it can also hold one elongated member 12. A cap is fitted to the upper end of the elongated member 12.

[0015] The retainer 10 includes a main body 20, a cover 24, a bend 26, and an assembly 28. The main body 20 has a first retaining part 22a and a second retaining part 22b (hereinafter referred to as "retaining part 22" without distinction). The first elongated member 12a and the second elongated member 12b are held in parallel arrangement. The direction along the central axis of the elongated member 12 is referred to as the axial direction X. The longitudinal direction Y of the cover 24 is orthogonal to the axial direction X.

[0016] The main body 20 has a central portion 32 that connects to a pair of retaining portions 22. An assembly portion 28 is provided on the main body 20. The assembly portion 28 can engage the strap, thereby securing the retaining member 10 to the side of the vehicle body.

[0017] A pair of retaining portions 22 are formed in a generally semi-cylindrical shape to retain the elongated member 12. The retaining portions 22 are open radially in the elongated member 12. A cover portion 24 is connected to the main body portion 20 via a bend portion 26, and the cover portion 24 is configured to rotate relative to the main body portion 20. The bend portion 26 is formed as a thin wall and is flexible. Through the bend portion 26, the cover portion 24 rotates to have a closed state that closes the opening of the retaining portion 22 and an open state that opens the opening of the retaining portion 22.

[0018] The elongated member 12 is radially pressed into the opening of the retaining portion 22 and held by it. Then, the cover portion 24 is closed, preventing the elongated member 12 from detaching from the retaining portion 22. The insertion direction Z of the elongated member 12 into the retaining portion 22 is orthogonal to the longitudinal direction Y of the cover portion 24 and the axial direction X of the elongated member 12, and is the direction of the opening of the retaining portion 22. (Refer to...) Figure 3 The components of the retainer 10 are described in detail.

[0019] Figure 3 (a) is a perspective view of the retainer 10 in the closed state as seen from above. Figure 3 (b) is Figure 3 (a) is a sectional view of the retainer 10 along line segment A-A. The first engaging portion 34 of the main body 20 is located on the top end side, and the second engaging portion 36 of the main body 20 is located on the base end side. The portion of the main body 20 connected to the turning portion 26 is designated as the base end. The first engaging portion 34 and the second engaging portion 36 are formed in a claw shape.

[0020] The retaining part 22 opens radially on the elongated member 12, and can accommodate the elongated member through the opening 31. The retaining part 22 has a C-shaped inner circumferential surface when viewed in the axial direction X. A pair of retaining parts 22 open in the same direction.

[0021] The retaining part 22 has a pair of wall-shaped parts 30 that form an opening 31 opposite each other. The wall-shaped parts 30 are provided opposite each other, and their opposing surfaces are curved according to the outer peripheral surface of the elongated member 12. The wall-shaped parts 30 protrude inward in the opposing direction. The opposing direction is the direction in which the retaining part 22 clamps the elongated member 12. The insertion direction Z of the elongated member 12 is from the opening 31 towards the inside of the retaining part 22. When the retaining part 22 holds the elongated member 12, the pair of wall-shaped parts 30 expand.

[0022] The central portion 32 is connected between the retaining portions 22. The first engaging portion 34 extends from the first retaining portion 22a and is formed on the outer side, and the second engaging portion 36 is formed on the outer surface of the second retaining portion 22b.

[0023] The cover portion 24 has a first locking portion 40, a second locking portion 42, a first protrusion 44a, and a second protrusion 44b. The first locking portion 40 is located on the top end side and is engaged with the first engaging portion 34, and the second locking portion 42 is located on the base end side and is engaged with the second engaging portion 36. The first locking portion 40 and the second locking portion 42 are formed in a claw shape.

[0024] When the first locking part 40 is engaged with the first engaging part 34, the cover 24 is in the closed state, and its rotation in the opening direction is restricted. It should be noted that when the cover 24 is in the closed state, it is hooked onto the main body 20 in the axial direction X, and its movement in the axial direction X is restricted. When the second locking part 42 is engaged with the second engaging part 36, the closed state can be maintained even if the turning part 26 breaks.

[0025] A first protrusion 44a and a second protrusion 44b (referred to as "protrusion 44" without distinction) are formed on the inner surface of the cover 24 opposite to the main body 20, and protrude into the opening 31 in the closed state. The protrusion 44 has ribs 46 extending to both sides. In the closed state, the protrusion 44 abuts against the outer peripheral surface of the elongated member 12, suppressing any shaking of the main body 20 and the cover 24. Furthermore, by forcefully abutting against the elongated member 12 through the protrusion 44, the elongated member 12 is pressed inwards towards the retaining portion 22 and stably held in place.

[0026] In the closed state, the protrusion 44 prevents the cover 24 from rotating in the closing direction solely by contacting the elongated member 12. That is, the contact between the protrusion 44 and the elongated member 12 prevents the cover 24 from approaching the main body 20. Therefore, even if there is a dimensional deviation between the main body 20 and the cover 24, the wobbling of the cover 24 can be suppressed as long as the protrusion 44 is in contact with the elongated member 12.

[0027] The protrusions 44 are respectively provided for a pair of retaining portions 22. The first protrusion 44a, located on the top side of the pair of protrusions 44, protrudes more than the second protrusion 44b. By abutting against the elongated member 12, the cover 24 generates a reaction force in a direction away from the main body 20, and the first locking portion 40 engages with the first engaging portion 34. Since the first protrusion 44a is formed higher, the first locking portion 40 will forcefully engage with the first engaging portion 34 in the closed state, and the first locking portion 40 and the first engaging portion 34 can be securely locked. Furthermore, since the second protrusion 44b is formed lower, in the closed state, the cover 24 tilts away from the main body 20 as it moves towards the top side, and the first locking portion 40 and the first engaging portion 34 can be securely locked.

[0028] The protrusion 44 is formed over approximately the entire inner surface of the cover portion 24 in the axial direction X. The protrusion 44 has a length of more than 90% of the axial length of the cover portion 24 in the axial direction X. As a result, axial vibration of the held elongated member 12 relative to the retainer 10 can be suppressed.

[0029] Figure 4 This is a cross-sectional view of the retaining structure 1 in the closed state. The first protrusion 44a contacts the first elongated member 12a, and the second protrusion 44b contacts the second elongated member 12b. The end face 32a of the main body 20, which is opposite to the cover 24, is configured not to abut against the cover 24 in the closed state.

[0030] That is, when the protrusion 44 abuts against the outer peripheral surface of the elongated member 12, a gap C is formed between the inner surface 24a of the cover 24 and the end face 32a of the main body 20 opposite to the inner surface 24a. A gap C1 is formed between the top of the first locking part 40 and the root of the first engaging part 34 of the main body 20. A gap C2 and a gap C3 are formed between the inner surface 24a of the cover 24 and the pair of wall-like parts 30 of the first retaining part 22a.

[0031] The inner surface 24a of the cover portion 24 and the end face 32a of the central portion 32 have a gap C4. The inner surface 24a of the cover portion 24 and a pair of wall-like portions 30 of the second retaining portion 22b have gaps C5 and C6. The movement of the cover portion 24 towards the main body portion 20 is prevented by the contact between the protrusion 44 and the elongated member 12, and the reaction force on the cover portion 24 in the opening direction is generated only through the abutment between the protrusion 44 and the elongated member 12. Therefore, the cover portion 24 presses against the elongated member 12, suppressing the swaying of the elongated member 12.

[0032] The end face 32a of the main body 20 is located along both sides of the opening 31. The two sides of the opening 31 are the top ends of the wall-like part 30 and are connected to the end face 32a of the main body 20. The gaps C2 and C3 on the top end side are larger than the gaps C5 and C6 on the base end side. As a result, the first protrusion 44a on the top end side of the cover 24 strongly abuts against the first elongated member 12a, and the first locking part 40 is firmly engaged with the first engaging part 34.

[0033] It should be noted that if the gap C6 is set to a small interval, it may become zero depending on the assembly state. In any case, the second protrusion 44b is pressed against the elongated member 12, and the movement of the cover 24 towards the main body 20 is prevented.

[0034] The inner surface 24a of the cover portion 24 and the end face 32a of the main body portion 20 may have gaps C2 and C3 at least on the top side of the cover portion 24 via the first protrusion 44a. The top side of the cover portion 24 may refer to the portion closer to the top than the center position of the cover portion 24 in the longitudinal direction Y. The inner surface 24a of the cover portion 24 and the end face 32a of the main body portion 20 may have gaps C2, C3, and C4 at least on the top side and in the center portion 32 of the cover portion 24.

[0035] The width W of the first protrusion 44a along the longitudinal direction Y of the cover portion 24 is at least 20% of the diameter D of the first elongated member 12a. The width of the second protrusion 44b is also the same as that of the first protrusion 44a, and the diameter of the second elongated member 12b is also the same as that of the first elongated member 12a. Since the bend 26 is formed as a thin wall and is easily flexible, the cover portion 24 may sometimes be locked off relative to the main body portion 20. Ensuring that the width of the protrusion 44 is sufficient, the protrusion 44 can abut against the cover portion 24 even when the cover portion 24 is locked off relative to the main body portion 20 in the longitudinal direction Y. More preferably, the width W of the first protrusion 44a can be at least 30% of the diameter D of the first elongated member 12a.

[0036] The surface of the protrusion 44 that contacts the elongated member 12 is flat. Assuming the protrusion 44 is semi-cylindrical, if the centers of the elongated member 12 and the protrusion 44 are misaligned in the longitudinal direction Y, the cover 24 may fail to close. By making the surface of the protrusion 44 flat, the elongated member 12 can be pressed perpendicularly to the surface of the protrusion 44 as long as the protrusion 44 is in contact with it. Therefore, it is possible to prevent the cover 24 from failing to close or from becoming closed under excessive load.

[0037] The present invention is not limited to the above embodiments. Various design changes and modifications can be made to the embodiments based on the knowledge of those skilled in the art, and embodiments with such modifications can also be included within the scope of the present invention.
