  Hereinafter, with reference to FIGS. 1-6, one Embodiment of the clamp of this invention is described.

  As shown in FIG. 1, the clamp 10 has a linear shape, a tubular shape or a rod shape such as a pipe or tube used in a fuel system or a cooling system of an automobile, or a cable or wire harness used in an electrical component. This is for holding a long object 5 and fixing it to an attachment hole 3 provided in a member 1 to be attached such as a vehicle body panel, and is provided with a main body 20 bent in a substantially U shape.

  The main body 20 bent in a substantially U shape has an inner periphery of the bent portion serving as a holding portion 30 for the elongated object 5, and both end portions are locking leg portions 50, 50 to the mounting holes 3 of the mounted member 1. I am doing.

  As shown in FIG. 2A, the holding part 30 has parallel surfaces 31 and 31 whose inner circumferences on the side of the locking leg part 50 are parallel to each other, and an inner circumference that is deeper than that has an arcuate surface 33. There is no. Further, on both sides of the holding part 30, a first opening 35 located on the side of the locking leg 50 and a second opening 37 located deeper than the first opening 35 are provided, respectively. An intermediate rib 39 is formed between 35 and 37.

  As shown in FIGS. 1 and 2B, the intermediate rib 39 has a tongue-like shape from the inner periphery on the first opening 35 side toward the first opening 35, and can be bent outward. An elastic holding piece 41 is extended. Each elastic holding piece 41 has an inner circumference bent in an arc shape (see FIG. 3A), and a tip portion 41a protrudes inward from the parallel surface 31 (see FIG. 2A). ). Furthermore, the interval W1 between the tip portions 41a and 41a (see FIG. 2A) is set to be smaller than the outer diameter of the long object 5. Therefore, when the long object 5 is pushed into the holding part 30, the tip part 41a is pressed by the long object 5, and the elastic holding pieces 41, 41 are bent outward and deformed (see FIG. 3B). When the maximum diameter portion of the long object 5 passes, it is elastically restored inward and engages with both sides of the long object 5 on the side of the locking leg (FIGS. 4A and 4B). reference).

  On the other hand, a tongue-like shape is formed from the inner periphery of the holding portion 30 behind the elastic holding piece 41, that is, from the inner periphery on the second opening 37 side of the intermediate rib 39 toward the second opening 37. An elastic pressing piece 43 that can be bent in the direction is extended (see FIGS. 1, 2B, and 3). The elastic pressing piece 43 extends along the circumferential direction of the holding portion 30 and has an inner circumference bent in an arc shape (see FIG. 3A). Further, a pressing protrusion 43 a is projected from the tip of the elastic pressing piece 43 toward the inside of the holding portion 30. The elastic pressing piece 43 is pressed against the outer periphery of the long object 5 on the back side of the holding part when the long object 5 is pushed into the holding part 30 to the maximum extent (FIG. 4). (See (b)).

  Further, on both inner sides of the holding portion 30 and on the inner periphery on the side of the locking leg 50 with respect to each elastic holding piece 41, retaining portions 45, 45 projecting inward from the parallel surface 31 are provided. Each is protruding. A distance W2 (see FIG. 2A) between the two retaining portions 45, 45 is set to be smaller than the outer diameter of the long object 5 and is a long length disposed in the holding portion 30. The object 5 is retained and retained (see FIGS. 4B and 5).

  On the other hand, the locking leg portions 50, 50 provided at both end portions of the main body 20 have shapes that protrude in parallel with each other from both ends of the holding portion 30. A pair of frame-like walls 51, 51 are erected on both sides of each locking leg 50 in the width direction (direction orthogonal to the extending direction). On the outer surface of each frame-like wall 51, a tapered guide surface 51 a that becomes gradually narrower toward the tip is formed, and the locking leg portion 50 is inserted into the mounting hole 3 of the mounted member 1. (See FIG. 3B). Moreover, the front-end | tip part 53 of the latching leg part 50 protrudes a little longer to the front end side than the said frame-shaped wall 51 (refer FIG. 2).

  Further, the engaging leg 50 protrudes from the engaging leg 50 so as to be engaged with the back surface of the attaching hole 3 when inserted into the attaching hole 3 of the attached member 1. An elastic engagement piece 57 is provided. That is, a pair of vertical slits 54, 54 are formed along the inside of the frame-shaped walls 51, 51, and the ends of the vertical slits 54, 54 on the holding unit 30 side are connected by the horizontal slit 55. , 55 is formed with an elastic engagement piece 57 that can be bent and protruded from the locking leg 50. Each elastic engagement piece 57 has an engagement protrusion 57a that protrudes inward of the main body 20 while the outer surface thereof forms a flat surface (see FIG. 2B). The protrusion 57a is adapted to engage with the back side of the mounting hole 3 (see FIG. 4B).

  As shown in FIGS. 1 and 2B, the extending direction of the locking leg 50 from the outer surface of the base side (holding part 30 side) of each frame-like wall 51 of the locking leg 50. A thin flange-like engagement portion 59 that can be bent is provided so as to project in a direction perpendicular to the projection. These engaging portions 59, 59 are adapted to engage with the surface side of the mounting hole 3 when the locking leg portion 50 is inserted into the mounting hole 3 of the mounted member 1. The engaging portion 59 may have a protruding shape or the like as long as it has a structure that engages with the surface side of the mounting hole 3.

  The clamp 10 described above is integrally formed of a synthetic resin such as polyethylene, polypropylene, polyamide, polyacetal, polybutylene terephthalate, or the like.

  Further, the main body 20 is defined as having a substantially U-shape, but may be any shape as long as it accepts a long object 5 such as a pipe or a tube and sandwiches the outer periphery of both sides of the long object 5, for example, The both sides of the main body 20 may be expanded outward at a predetermined angle to form a V shape or the like, or may be formed in a U shape as a whole.

  Next, the usage method and effect of this clamp will be described.

  As shown in FIG. 1, a pair of elongated mounting holes 3, 3 are formed in a mounted member 1 such as a vehicle body panel, and a metal pipe or the like is formed on the surface of the mounted member 1. A long object 5 is arranged in advance.

  Then, as shown in FIG. 3A, the locking legs 50, 50 of the clamp 10 are aligned with the mounting holes 3, 3, respectively, and the clamp 10 is pushed toward the mounted member 1. Then, the front end portions 53 of each locking leg 50 are pressed against the outer periphery of the long object 5, the substantially U-shaped main body 20 is pushed open, and the engaging protrusion 57 a is attached to the long object 5. The long object 5 is inserted into the holding portion 30 while the elastic engagement piece 57 is bent outwardly from the locking leg portion 50 while being pressed.

  When the long object 5 gets over the elastic engagement piece 57 and further gets over the retaining portion 45, it comes into contact with the tip 41 a of the elastic holding piece 41 as shown in FIG. At this time, when the main body 20 is opened, the pair of locking leg portions 50 expands, and it becomes difficult to insert the distal end portion 53 into the attachment 3. However, as shown in FIG. Since the elastic holding piece 41 is bent and deformed outward from the holding portion 30 by being pressed against both side surfaces of the long object 5, it is possible to squeeze the locking leg portion 50 and insert the tip end portion 53 into the mounting hole 3. it can. Thus, when the locking leg 50 is inserted into the mounting hole 3, the guide surface 51 a of the locking leg 50 is brought into sliding contact with the outer peripheral edge of the mounting hole 3, and the main body 20 is gradually guided in the closing direction.

  When the clamp 10 is further pushed and the tip 41a of the elastic holding piece 41 gets over the maximum diameter portion of the long object 5, the elastic holding piece 41 is elastically restored and held as shown in FIG. It is pushed inward of the portion 30 and is pressed against both sides of the long object 5 on the side of the locking leg 50. Further, the engagement protrusion 57 a of the elastic engagement piece 57 inserted into the attachment hole 3 is pressed against the inner peripheral edge of the attachment hole 3, and the elastic engagement piece 57 is bent and deformed outward of the locking leg 50. Thus, the mounting hole 3 can be passed (see FIG. 4A).

  When the clamp 10 is further pushed in from the above state and the engagement protrusion 57a of the elastic engagement piece 57 passes through the attachment hole 3, the elastic engagement piece 57 is elastically restored, and the engagement protrusion 57a becomes the attachment hole. 3, the thin flange-like engagement portion 59 engages with the front side periphery of the mounting hole 3. When the long object 5 is pushed into the holding part 30, the pressing protrusions 43 a and 43 a of the elastic pressing pieces 41 and 41 are pressed against the outer periphery of the long object 5 on the back side of the holding part 30.

  As a result, the long object 5 pushed into the holding portion 30 is pressed by the elastic holding pieces 41 on both sides of the locking leg portion 50 side, and the outer periphery behind the holding portion 30 is pressed by the elastic holding pieces 43 and 43. The retaining leg 30 is supported and held in the holding portion 30. On the other hand, in the locking leg portion 50, the elastic engagement piece 57 engages with the peripheral edge on the back surface side of the attachment hole 3 and the engagement portion 59 is on the front side of the attachment hole 3. It engages with the periphery and is fixed to the mounting hole 3.

  As described above, according to the clamp 10, the distal end portion 53 of the locking leg portion 50 can be attached without floating the long object 5 that is previously disposed on the attached member 1 and is difficult to move. The long object 5 can be firmly fixed to the mounted member 1 by a simple operation of aligning with the holes 3 and 3 and pushing the clamp 10 toward the mounted member 1.

  FIG. 5 shows a state in which a long object such as a metal pipe disposed on the surface of the attached member 1 is pressed against the attached member 1 side by an external force or the like. At this time, since the elastic holding pieces 41 and 41 that can be bent are bent and deformed outward from the holding portion, there is a possibility that the long object 5 may come off from the holding portion 30. However, in this embodiment, the retaining portions 45, 45 set so as to be smaller than the outer diameter of the long object 5 are provided on the retaining leg portion 50 side of the holding portion 30. Further movement of the long object 5 is prevented by the retaining part 45, and the long object 5 can be reliably retained in the holding part 30.

  In this embodiment, as described above, the tapered leg 50 is attached to the outer surface of each locking leg 50 by forming the tapered guide surface 51a gradually narrowing toward the tip. When inserted into the hole 3, the guide surface 51 a comes into sliding contact with the inner periphery of the mounting hole, and the main body 20 is gradually guided in the closing direction. Therefore, when the long object 5 is inserted into the holding part 30, the elastic holding pieces 41, 41 are pressed against the long object 5 to open the main body 20 as shown in FIG. Even if a force is applied, the elastic holding pieces 41 and 41 can be drawn into the holding portion 30 against the force, so that the long object 5 passes between the elastic holding pieces 41 and 41. It can be made easier and workability can be improved.

  Furthermore, in this embodiment, an elastic presser piece 43 that protrudes from the holding part 30 so as to protrude and retract is provided on the inner periphery behind the elastic holding piece 41 of the holding part 30. Therefore, in addition to the elastic holding pieces 41, 41 engaging with the outer circumferences on both sides of the long object 5 on the attached member 1 side, the elastic holding pieces 41 and 41 are elastic on the outer circumference of the long object 5 disposed behind the holding portion 30. Since the presser pieces 43 are pressed against each other (see FIG. 4B), the long object 5 can be held more stably without rattling.

  Further, in forming the elastic pressing piece 43 and the elastic holding piece 41, in this embodiment, the first opening 35 and the second opening 37 are provided on both sides of the holding portion 30, An elastic holding piece 41 extends in the form of a tongue from the intermediate rib 39 toward the first opening 35, and elastic in the form of a tongue from the intermediate rib 39 toward the second opening 37. A presser piece 43 is extended (see FIGS. 1, 2B, and 3). Therefore, particularly when the long object 5 having a large outer diameter is held, the lengths of both the pieces 41 and 43 can be ensured as long as possible, and the elastic force of the both pieces 41 and 43 can be increased to increase the length within the holding unit 30. The backlash of the long object 5 can be more effectively prevented.

  Furthermore, in this embodiment, since the elastic engagement piece 43 protrudes inward of the locking leg portion 50 (engagement protrusion 57a), it is a long length disposed on the attached member 1. The elastic engagement pieces 43 and 43 are pressed by the long object 5 entering the main body 20 when the clamp 10 is pushed toward the object 5 (see FIG. 3A). 20 can be easily opened, and the elastic engagement pieces 43 and 43 are bent outwardly in contact with the outer peripheral edge of the mounting hole 3 (see FIG. 4A). The operation of holding the long object 5 can be performed smoothly. Furthermore, since the elastic engagement piece 43 protrudes inward of the locking leg 50, the portion protruding outward of the locking leg 50 can be reduced, and the mounting space for the clamp 10 can be reduced. .

  6-8 show another embodiment of the clamp of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the clamp 10a of this embodiment, the shape of the holding portion 30a is different from that of the previous embodiment. The holding portion 30a is formed so that the interval between the parallel surfaces 31, 31 is narrower than that of the holding portion 30 of the above-described embodiment (see FIG. 7A), and the wall portions on both sides in the width direction. 34 and 34 are wide compared with the thing of the said embodiment, and have comprised the shape extended diagonally outward.

  On both sides of the holding portion 30a, a first opening 35 located on the side of the locking leg 50 and a second opening 37 located deeper than the first opening 35 are provided, respectively. Intermediate ribs 39 are formed between 37.

  As shown in FIGS. 6, 7 (b) and 8, an elastic holding piece 44 having a tongue-like shape and capable of bending extends from the inner periphery of the first opening 35 on the locking leg 50 side. It is installed. As shown in FIG. 8, the elastic holding piece 44 includes a base portion 44 a extending obliquely inward toward the holding portion inward, and a distal end portion 44 b extending along the insertion direction of the long object 5 into the holding portion 30. The leading end portion 44b is a portion that presses both sides of the long object 5 on the locking leg portion 50 side. On the other hand, from the center of the end face of the intermediate rib 39 on the second opening 37 side, a tongue piece is formed toward the second opening 37 side, and an elastic presser piece 43 that can be bent is extended.

  According to this embodiment, the elastic holding piece 44 extends in a tongue-like shape from the inner surface of the first opening 35 on the side of the locking leg 50 and is directed from the intermediate rib 39 toward the second opening 37. Since the elastic pressing piece 43 is extended in the form of a tongue piece, the length of both pieces 44 and 43 can be ensured as long as possible, particularly when the long object 5 having a small outer diameter is held. The elastic force of the pieces 44 and 43 can be increased and the looseness of the long object 5 in the holding part 30 can be more effectively prevented.
