The central axes O1, O2 each define a respective horizontal plane O1H, O2H and a respective vertical plane O1V, O2V that is perpendicular to the respective horizontal plane O1H, O2H.
(24) In
(25) The insert 110 has a base part 112 and a pair of arms 114, 116 extending from the sides of the base part 112. The arms 114, 116 have respective heads 118, 120 formed on the ends thereof. The insert 110 is a member having a substantially C shape with an open upper portion, and can be integrally formed from a plastic material such as polyacetal, polyamide, or polypropylene. The arms 114, 116 of the insert 110 form a retention channel 122 in which the cylindrical component 160 is retained. Notches 114a, 116a extending in the central axis O1 direction may be formed in the inner surfaces of the arms 114, 116.
(26) The inner peripheral surface of the retention channel 122 is formed so as to contact with the outer peripheral surface of the cylindrical component 160 to be retained. The inner peripheral surface of the retention channel 122 can be formed from a part of a substantially cylindrical surface centered on the central axis O1. Each of the heads 118, 120 of the arms 114, 116 contacts the outer surface, which is the upper side, of the outer peripheral surface of the cylindrical component 160 arranged in the channel 122, i.e., the outer surface which is the rear side of the cylindrical component 160 when viewed in the fitting direction V, and press the cylindrical component 160 downward from above.
(27) The base part 112 is formed with protrusions protruding from the front and back. Furthermore, though only the front protrusions 112a formed on the front surface of the base part 112 is shown in
(28) The heads 118, 120 are formed on the tips (upper ends) of the arms 114, 116. The heads 118, 120 project in the front-rear direction from the arms 114, 116, and are substantially T-shaped in a side view. Contact parts 118b, 120b are formed by the portions of the heads 118, 120 protruding in the front-rear direction. The inner peripheral surfaces of the heads 118, 120 are formed so as to be in contact with the peripheral surface of the cylindrical component to be retained, and form a part of the retention channel 122.
(29) The holder 130 has a front wall 132 and a rear wall 134 arranged in parallel, and side walls 136, 138 extending between the front wall 132 and rear wall 134 and connecting the two. The front wall 132 and the rear wall 134 have respective channels 144, 146 which can contact the outer peripheral surface of the cylindrical component 160 to be retained, and are formed in a substantially U shape. The channels 144, 146 are formed in an arc shape or a semicircular shape around the central axis O2. Stop surfaces 132a, 132b; 134a, 134b are formed on the ends of the channels 144, 146 in the circumferential direction.
(30) The arms 140, 142 are formed by the front wall 132, the rear wall 134 and the side walls 136, 138. Grooves 136a and 138a extending in the fitting direction V perpendicular to the central axis O2 are formed in the inner surfaces of the arms 140, 142 facing each other. In the arms 140, 142, the end surfaces 140a, 142a, which are the rear ends when viewed in the fitting direction V, are preferably arranged in the same plane perpendicular to the fitting direction V.
(31) Further, recesses are formed in the portions of the front wall 132 and rear wall 134 (the base portion of the holder) that face the base part 112 of the insert 110 (the base part of the holder), so that when the insert 110 is fitted into the holder 130, the protrusions (front protrusions 112a and back protrusions 112a) engage in the recesses. Though only the back recesses 134c formed in the rear wall 134 of the holder 130 are shown in the attached drawings, in particular
(32) The mode of operation of the present embodiment will be described below.
(33) The insert 110 is positioned relative to the holder 130 so that the base part 112 is located between the arms 140, 142 of the holder 130, as shown in
(34) Furthermore, when the hook parts 124, 126 of the insert 110 are received in the grooves 136a, 138a of the holder 130, the hook parts 124, 126 can move along the grooves 136a, 138a but cannot move beyond the walls 136b, 138b at the upper ends of the grooves 136a, 138a to be removed from the grooves 136a, 138a, and as a result, the insert 110 cannot be separated from the holder 130.
(35) As shown in
(36) When the insert 110 is further pressed in the fitting direction V along with the cylindrical component 160, the insert 110 is fitted into the holder 130 in a state in which the cylindrical component 160 is retained in the retention channel 112 thereof (
(37) Further, the protrusions (front protrusions 112a and back protrusions) of the base part 112 of the insert 110 engage with the recesses (front recesses 132c and back recesses 134c) of the holder 130, and as a result, the base part 112 of the insert 110 is affixed to the base portion of the holder 130. Thus, the insert 110 is fitted into and affixed in the holder 130 in a state in which the cylindrical component 160 is retained in the retention channel 112.
(38) In the present embodiment, the shoulders 118a, 120a of the heads 118, 120 of the insert 110, which engage with the shoulders 140b, 142b of the holder 130, and the protrusions of the base part 112 of the insert 110, which engage with the recesses of the holder 130, form a locking part for retaining the fitted state of the insert 110 and the holder 130.
(39) At this time, when the insert 110 and the holder 130 are fitted with each other, as described above, in a state in which the cylindrical component 160 is retained in the retention channel 122, the central axis O of the cylindrical component 160, the central axis O1 of the insert 110, and the central axis O2 of the holder 130 coincide with each other, and the inner peripheral surface of the retention channel 122 of the insert 110 coincides with the inner peripheral surface of the channel 144 of the holder 130.
(40) Furthermore, when the insert 110 and the holder 130 are fitted with each other, in the present embodiment, the surfaces (rear end surfaces) 118c, 120c of the heads 118, 120 of the arms 114, 116 of the insert 110 , which are the rear ends when viewed in the fitting direction V, are arranged in substantially the same plane as the end surfaces 140a, 142a of the arms 140, 142 of the holder 130, as shown in
(41) Furthermore, in the present embodiment, when the insert 110 is fitted into the holder 130 in a state in which the cylindrical component 160 is received, since the insert 110 is entirely retained by the holder 130 so as to be urged from the outside toward the center axis O of the cylindrical component 160, even if the insert 110 is made of a flexible material, the cylindrical component 160 can be firmly retained.
(42) Further, in the routing clip assembly of Patent Literature 1, since the tubular part is pressed toward the insert by the claws from above, the vertical dimension (height) of the routing clip assembly for inserting the tubular part thereinto is relatively large. However, in the present embodiment, the entirety of the insert 110 is retained from the outside by the holder 130, and at this time, since the heads 118, 120 retain the outer surface above the central axis O of the cylindrical component 160 (the outer surface of the cylindrical component 160 on the rear side when viewed in the fitting direction V) from above, the height of the clip assembly can be reduced.
(43) Though the clip assembly 100 is configured such that a single cylindrical component 160 is retained in the embodiment described above, the present invention is not limited thereto, and the clip assembly 100 may be configured so as to retain a plurality of cylindrical components 160. In the clip assembly 150 shown in
(44) Further, the clip assembly of the present invention may comprise an anchor for affixation to a stationary member (not illustrated) such as a frame or panel affixed to the engine compartment of a motor vehicle. With reference to

The insert 210 is pushed in the fitting direction V with respect to the holder 240, whereby it is fitted into and integrates with the holder 240. The holder 240 can be affixed to a stationary member such as a frame or panel.
(49) The insert 210 has a base part 212 and a pair of arms 214, 216 extending from the sides of the base part 212. The arms 214, 216 have heads 218, 220 formed at their respective tips. The insert 210 is a member having a substantially C shape with an open upper portion, and can be integrally formed from a plastic material such as polyacetal, polyamide, or polypropylene. The arms 214, 216 of the insert 210 form a retention channel 222 which retains the cylindrical component 160. Noches 214a and 216a extending in the central axis O1 direction may be formed in the inner surfaces of the arms 214, 216.
(50) The inner peripheral surface of the retention channel 222 can be in contact with the outer peripheral surface of the cylindrical component 160 to be retained. The inner peripheral surface of the retention channel 222 can be formed from a part of a substantially cylindrical surface centered on the central axis O1. The heads 218, 220 of the arms 214, 216 contact the upper side of the outer peripheral surface of the cylindrical component 160 arranged in the channel 222, and press the cylindrical component 160 downward from above.
(51) The base part 212 has a pair of hook parts 224, 226 which extend diagonally upward from the base part 212 symmetrically when the insert 210 is viewed from the front or the rear. The hook parts 224, 226 are arranged more outwardly than the arms 214, 216. The hook parts 224, 226 preferably extend obliquely upward from the ends of base part 212. The base part 212 does not have protrusions like the clip assembly 100 according to the first embodiment.

Contact parts 218b, 220b are formed by the portions of the heads 218, 220 protruding in the front-rear direction. The inner peripheral surfaces of the heads 218, 220 are formed so as to be in contact with the peripheral surface of the cylindrical component to be retained, and form a part of the retention channel 222.
(53) Locking fingers 228, 230 are also formed on the tips of the arms 214, 216. The locking fingers 228, 230 project obliquely upward from the tips of the arms 214, 216. The locking fingers 228, 230 are arranged more laterally outwardly than the heads 218, 220 of the arms 214, 216.
(54) The heads 218, 220 also have flexible biasing parts 232, 234 protruding into the retention channel 222. The biasing parts 232, 234 are formed so as to project inward from the inner peripheral surfaces of the heads 218, 220 so as to contact the outer surface of the cylindrical component 160 retained in the retention channel 222. Further, exit grooves 232a, 234a extending in the central axis O1 direction are formed around the biasing parts 232 and 234 to enable the biasing parts 232, 234 to be removed from the retention channel 222 when the biasing parts 232, 234 contact the outer surface of the cylindrical component 160 retained in the retention channel 222. The flexible biasing parts 232, 234 prevent the clip assembly 200 for the cylindrical component from moving axially or circumferentially with respect to the retained cylindrical component 160.
(55) The holder 240 has a front wall 242 and a rear wall 244 arranged in parallel, and side walls 246, 248 extending between the front wall 242 and the rear wall 244 and connecting the two. The front wall 242 and the rear wall 244 have channels 254, 256 which can contact the outer peripheral surface of the cylindrical component 160 to be retained, and are formed in a substantially U-shapes.

Grooves 246a, 248a extending in the fitting direction V perpendicular to the central axis O2 are formed in the inner surfaces of the arms 250, 252 facing each other. The end surfaces 250a, 252a of the arms 250, 252, which are the rear ends with respect to the fitting direction V, are preferably arranged in the same plane perpendicular to the fitting direction V.
(58) In the present embodiment, the locking fingers 228, 230 engage with the walls 246b, 248b on the upper sides of the grooves 246a, 248a to form a locking part which retains the fitted state of the insert 210 and the holder 240. At this time, the locking fingers 228, 230 also bias the heads 218, 220 of the arms 214, 216 toward the cylindrical component 160 in the retention channel 222.
(59) The insert 210 is arranged between the arms 250, 252 of the holder 240, pushed in the fitting direction V, and fitted in the holder 240, as shown in
