The present invention provides a holder capable of ensuring the holding performance of the member to be held and improving the assembly workability.

In the first aspect of the present invention, a pair of holding portions disposed in a direction intersecting the axial direction of the elongated held member and the pair of holding portions are connected so as to be openable and closable to be in a closed state. The pair of holding portions includes a hinge portion that sandwiches the outer peripheral portion of the held member, an attachment portion that is formed at a free end of the pair of holding portions and is attached to the attached member, and an inner portion of the pair of holding portions. Projecting to the hinge part side on the peripheral surface, projecting to the free end side on the inner peripheral surface of the pair of holding parts and axial ribs along the axial direction of the holding part, and surrounding the holding part A retainer is provided having circumferential ribs along the direction.

In the above aspect, the hinge portion is closed and the outer peripheral portion of the held member is sandwiched between the pair of holding portions, and the attachment portion formed at the free ends of the pair of holding portions is attached to the attached member. In addition, an axial rib along the axial direction of the holding portion is formed to protrude toward the hinge portion on the inner peripheral surface of the pair of holding portions, and a circumferential rib along the circumferential direction of the holding portion is formed between the pair of holding portions. It protrudes and is formed on the free end side on the inner peripheral surface. That is, when the hinge portion is closed, the circumferential rib is formed on the free end side where the distance of sliding with the outer peripheral portion of the held member is longer than the hinge portion side on the inner peripheral surface of the pair of holding portions. ing. For this reason, when the pair of holding portions move in the closing direction with the hinge portion as a fulcrum, the axial ribs and the circumferential ribs easily bite into the outer peripheral portion of the held member. As a result, the reaction force acting on the axial rib and the circumferential rib from the held member is reduced, and a large assembling force is not required, so that the assembling workability is improved. In addition, when the hinge portion is closed, the axial rib and the circumferential rib bite into the outer peripheral portion of the member to be held and prevent movement in the axial direction and rotation in the circumferential direction.

Not easily affected. As a result, the assembly workability is further improved.

In the third aspect of the present invention, at least the tips of the circumferential ribs may have an acute angle in the first or second aspect of the present invention.

In the above aspect, since at least the tip of the circumferential rib has an acute angle, at least the circumferential rib easily bites into the held member. For this reason, it is hard to receive the influence of the reaction force of the to-be-held member at least produced by the circumferential rib, and the assembly workability is further improved. Further, at least the holding performance in the axial direction is further improved.

According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the axial rib may be extended over the entire region along the axial direction of the pair of holding portions.

In the above aspect, since the axial rib is extended over the entire area along the axial direction of the pair of holding portions, the holding performance in the circumferential direction is further improved.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects of the present invention, the attachment portion may include a lock portion that holds the hinge portion in a closed state.

Next, an embodiment of the holder of the present invention will be described with reference to FIGS.
In the drawings, members (components) having the same or corresponding functions are denoted by the same reference numerals and description thereof is omitted as appropriate.

As shown in FIG. 2, the holder 10 of the present embodiment includes, for example, a long holding member such as a vehicle LLC (cooling water) hose 12 (holding member) and a reserve tank 14 (attachment). Used when fixing to a member to be attached.

As shown in FIG. 1, the holder 10 of this embodiment is comprised by materials, such as a resin material which has elasticity as an example. The holder 10 is attached to a pair of holding portions 18 that hold the LLC hose 12, a hinge portion 20 that connects the pair of holding portions 18 so as to be openable and closable, and an attachment hole 16 formed in the reserve tank 14. A pair of attachment portions 22. Further, the pair of holding portions 18 of the holding tool 10 is substantially circular with the hinge portion 20 closed, and can hold the LLC hose 12 with the hinge portion 20 closed. . Further, as shown in FIG. 2, the pair of holding portions 18 are arranged in a circumferential direction (arrow Y direction in FIG. 2) that intersects the axial direction (arrow X direction in FIG. 2) of the long LLC hose 12. Has been.

As shown in FIG. 4, each of the pair of holding portions 18 of the holder 10 has a plate shape curved in a semicircular arc shape, and the end portions 18 A on the hinge portion 20 side are connected to each other by the hinge portion 20. ing. On the other hand, the other ends of the pair of holding portions 18 are free ends 18B, and the pair of attachment portions 22 are formed at the free ends 18B of the pair of holding portions 18, respectively.

As shown in FIG. 5, the pair of attachment portions 22 are provided with semicircular flange portions 24, and these flange portions 24 have a circular umbrella shape when the hinge portion 20 is closed. In addition, when the hinge portion 20 is closed and the pair of attachment portions 22 are umbrella-shaped, leg portions 26 are formed at portions that become the central portion of the umbrella shape. These leg portions 26 have a truncated cone shape with a diameter reduced from the flange portion 24 side toward the distal end side with the hinge portion 20 closed. Further, an engaging claw 28 (locking portion) and an engaging portion 30 (locking portion) as a locking portion are formed on the base portion 26A of each leg portion 26. When the hinge portion 20 is closed, these engaging claws 28 engage with an engaging portion 30 formed on the base portion 26A of the opposite leg portion 26, and as shown in FIG. It is designed to keep it closed. On the other hand, convex portions 32 are formed at the distal ends 26B of the pair of leg portions 26, respectively. These convex portions 32 protrude toward each other in a direction approaching the tip 26 B of the other leg portion 26.

As shown in FIG. 1, when the hinge portion 20 is closed, the tip 32A of the convex portion 32 of the leg portion 26 of the pair of attachment portions 22 covers the tip 26B of the other leg portion 26. Further, plate-like engaging claws 40 are extended from the distal ends 26B of the pair of leg portions 26 in the direction of the root portion 26A of the leg portion 26, respectively. These engaging claws 40 are inclined in the outward direction from the tip 26B of the leg portion 26B toward the root portion 26A, that is, in the direction in which the pair of engaging claws 40 spread, and the inner side with the tip 26B side as a fulcrum. It can be elastically deformed (in the direction of arrow A in FIG. 1). Therefore, when the pair of engaging claws 40 are inserted into the mounting holes 16 of the reserve tank 14, they are elastically deformed in the direction of arrow A in FIG. Further, when the pair of engaging claws 40 pass through the mounting hole 16, the pair of engaging claws 40 return to the original direction (the direction opposite to the arrow A in FIG. 1) and engage with the peripheral edge of the mounting hole 16. As a result, the pair of engaging claws 40 sandwich the peripheral edge portion of the mounting hole 16 in the reserve tank 14 with the flange portion 24.

As shown in FIG. 3, axial ribs 44 project from the hinge portion 20 side of the inner peripheral surface 18 C of the pair of holding portions 18. These axial ribs 44 are formed in a straight line along the axial direction of the holding portion 18, and are extended to the entire region L 1 along the axial direction of the pair of holding portions 18. Accordingly, the holding performance in the circumferential direction of the LLC hose 12 is further improved. In addition, since the front end 44 A of each axial rib 44 has an acute angle, each axial rib 44 easily bites into the outer peripheral portion 12 A of the LLC hose 12.

As shown in FIG. 4, circumferential ribs 46 project from the attachment portion 22 side of the inner peripheral surface 18 C of the pair of holding portions 18. These circumferential ribs 46 are linearly formed along the circumferential direction of the holding portion 18.

That is, as shown in FIG. 7, when closing the hinge portion 20, the hinge portion 20 slides with the outer peripheral portion 12 A of the LLC hose 12 as compared with the portion on the inner peripheral surface 18 C of the pair of holding portions 18 on the hinge portion 20 side. On the free end 18B side where the distance in the circumferential direction (arrow D direction in FIG. 7) is increased, circumferential ribs 46 are formed along the circumferential direction of the pair of holding portions 18. Accordingly, when the pair of holding portions 18 move in the closing direction (in the direction of arrow B in FIG. 7) with the hinge portion 20 as a fulcrum, the axial ribs 44 and the circumferential ribs 46 are connected to the LLC hose 12. It is easy to bite into the outer peripheral portion 12A.

Further, since the tip 46A of each circumferential rib 46 has an acute angle, each circumferential rib 46 is more easily bite into the outer peripheral portion 12A of the LLC hose 12.

As shown in FIG. 1, the axial ribs 44 and the circumferential ribs 46 are not formed at the circumferential free ends 18 B of the pair of holding parts 18 of the holder 10 and the central part 18 D of the hinge part 20. Therefore, as shown in FIG. 7, when the operator presses the circumferential free ends 18 B of the pair of holding portions 18 and the central portion 18 D of the hinge portion 20 toward each other with the thumb S 1 and the index finger S 2. The influence of the reaction force of the LLC hose 12 acting on the axial rib 44 and the circumferential rib 46 is less likely to be affected.

(Action / Effect)
Next, the operation and effect of this embodiment will be described.
When the LLC hose 12 is fixed to the reserve tank 14 using the holder 10 of the present embodiment, first, as shown in FIG. The LLC hose 12 is inserted between the holding portions 18.

Next, as shown in FIG. 7, for example, the operator holds the pair of holding portions 18 with the thumb S 1 and the index finger S 2 and closes the hinge portion 20.

Then, as shown in FIG. 8, when the operator further closes the hinge part 20 of the holder 10, the engagement claw 28 and the engagement part 30 of the attachment part 22 are engaged, and the hinge part 20 is closed. Can be kept in a state. Thereafter, the holder 10 is moved in the direction of insertion into the mounting hole 16 of the reserve tank 14 (in the direction of arrow C in FIG. 8), and the leg portion 26 of the mounting portion 22 is moved to the mounting hole of the reserve tank 14 as shown in FIG. 16 is inserted into the mounting hole 16 of the reserve tank 14.

At this time, in the holder 10 of the present embodiment, the axial ribs 44 are formed to protrude toward the hinge part 20 on the inner peripheral surface 18 C of the pair of holding parts 18, and the circumferential ribs 46 of the pair of holding parts 18. The inner peripheral surface 18C is formed to protrude toward the free end 18B. That is, when closing the hinge part 20, compared with the hinge part 20 side on the inner peripheral surface 18C of the pair of holding parts 18, the circumferential direction sliding with the outer peripheral part 12A of the LLC hose 12 (the direction of arrow D in FIG. 7). The circumferential ribs 46 are formed along the circumferential direction of the pair of holding portions 18 on the free end 18B side where the distance (2) becomes longer. Therefore, as shown in FIG. 7, when the pair of holding portions 18 moves in the closing direction (in the direction of arrow B in FIG. 7) with the hinge portion 20 as a fulcrum, each axial rib 44 and each circumferential rib 46 can easily bite into the LLC hose 12. As a result, in the holder 10 of the present embodiment, the reaction force from the LLC hose 12 can be reduced, and a large assembling force is not required, so that the assembling workability can be improved.

Further, in the holder 10 of the present embodiment, the axial ribs 44 and the circumferential ribs 46 bite into the outer peripheral portion 12A of the LLC hose 12. For this reason, since the movement in the axial direction of the hose 12 for LLC and the rotation to the circumferential direction can be prevented, the holding | maintenance performance of the hose 12 for LLC can be ensured.

Further, in the holder 10 of the present embodiment, the axial ribs 44 and the circumferential ribs 46 are not formed on the circumferential free ends 18B of the pair of holding parts 18 and the central part 18D of the hinge part 20. Therefore, as shown in FIG. 7, when the operator presses the circumferential free end 18 B of the pair of holding portions 18 and the central portion 18 D of the hinge portion 20 toward each other with the thumb S 1 and the index finger S 2. Furthermore, it is difficult to be affected by the reaction force of the LLC hose 12 acting on the axial rib 44 and the circumferential rib 46. As a result, in the holder 10 of this embodiment, the assembly workability can be further improved.

Further, in the holder 10 of the present embodiment, the tip 46A of the circumferential rib 46 and the tip 44A of the axial rib 44 have an acute angle. For this reason, the circumferential rib 46 and the axial rib 44 are likely to bite into the outer peripheral portion 12A of the LLC hose 12, and are less susceptible to the reaction force of the LLC hose 12 generated by the circumferential rib 46 and the axial rib 44. . As a result, in the holder 10 of this embodiment, the assembly workability can be further improved. Further, since the distal end 46A of the circumferential rib 46 and the distal end 44A of the axial rib 44 deeply bite into the outer peripheral portion 12A of the LLC hose 12, the holding performance in the axial direction and circumferential direction of the LLC hose 12 can be further improved.

Moreover, in the holder 10 of this embodiment, since it is extended to the whole region L1 along the axial direction of a pair of holding | maintenance part 18, the holding | maintenance capability with respect to the circumferential direction of the hose 12 for LLC further improves.

Moreover, in the holder 10 of this embodiment, when the hinge part 20 is closed, the engaging claw 28 of one leg part 26 of a pair of attachment part 22 engages with the engaging part 30 of the other leg part 26. Then, the hinge part 20 is held in a closed state. For this reason, it becomes easy to insert the leg part 26 of the attachment part 22 in the attachment hole 16 of the reserve tank 14, and an assembly workability | operativity further improves.

It will be apparent to those skilled in the art. For example, in the above-described embodiment, the axial direction rib 44 and the circumferential rib 46 are not formed on the circumferential free end 18B of the pair of holding portions 18 and the central portion 18D of the hinge portion 20, but instead. The axial ribs 44 or the circumferential ribs 46 may be formed on the circumferential free ends 18B of the pair of holding portions 18 and the central portion 18D of the hinge portion 20.

In the above embodiment, the tip 46A of the circumferential rib 46 and the tip 44A of the axial rib 44 have an acute angle, but instead, only the tip 46A of the circumferential rib 46 may have an acute angle. Further, only the tip 44A of the axial rib 44 may have an acute angle, or both the tip 46A of the circumferential rib 46 and the tip 44A of the axial rib 44 may have an arc shape.

In the present embodiment, the axial ribs 44 are extended to the entire region L1 along the axial direction of the pair of holding portions 18. Instead, the axial ribs 44 are extended in the axial direction of the pair of holding portions 18. It is good also as a structure formed in a part along.

Moreover, in the said embodiment, although it was set as the structure which hold | maintains the hinge part 20 in the closed state by the engagement nail | claw 28 and the engagement part 30 as a lock part, it replaces with this and hinges by another lock part.
