DETAILED DESCRIPTION OF THE INVENTION

(21) An embodiment of the present invention will be described with reference to FIGS. 1 to 20. As shown in FIG. 1, a clip attachment structure has a clip 1, a mounting member, and a panel. The mounting member may be, for example, a cover 2 that is an interior component of a vehicle door. The panel may be, for example, an inner panel 3 of a vehicle door. The cover 2 may be mounted to the inner panel 3 by the clip 1.

(22) As shown in FIGS. 2 and 3, the clip 1 has an anchor portion 10 and an attachment section 20. The anchor portion 10 is mounted to the inner panel 3. The attachment section 20 is attached to the cover 2. The anchor portion 10 has a base plate 12 and a pair of elastic claws 14a. The base plate 12 may have a generally rectangular configuration. A pillar 14 extends from the center of the base plate 12, and the elastic claws 14a extend laterally from the pillar 14. A pair of detachment prevention members 12a extend from the longitudinal edges of the base plate 12. The detachment prevention members 12a extend from approximately the center of the longitudinal edges so as to be substantially parallel to the upper surface of the base plate 12.

(23) As shown in FIGS. 2 and 3, the base plate 12 includes a pair of compressible and/or elastic members 12b. The elastic members 12b extend obliquely away from the base plate 12 in a direction opposite the direction in which the pillar 14 extends. The elastic members 12b are provided in the vicinity of the short edges of the base plate 12. The short edges are shorter in length than the longitudinal edges, and extend in a direction orthogonal to the longitudinal direction. Also, each elastic member 12b has an opposite surface on the opposite side of the base plate 12. A protrusion 12c is located on each opposite surface. The protrusions 12c may elastically reposition in correspondence with elastic deformation of the elastic members 12b (elastic protrusions).

(24) As shown in FIGS. 2 and 3, the attachment section 20 has a pillar 22, a flange 24, and a stabilizer 26. The pillar 22 may be generally configured as a column. The pillar 22 extends from the base plate 12 in a direction opposite the direction in which the pillar 14 extends. The flange 24 protrudes from the outer peripheral surface of the pillar 22. The stabilizer 26 is formed at the distal end of the pillar 22.

(25) Referring generally now to FIGS. 10 and 12, the flange 24 and the elastic members 12b may pinch and/or squeeze a mounting area 30. The reaction force associated with recovering from compression and/or deflection of the elastic members 12b may be applied to a surface 30a of the mounting area 30. Such a restorative force may suppress detachment of the attachment section 20 from the mounting area 30.

(26) When the attachment section 20 is attached to the mounting area 30 of the cover 2, a restorative force associated with recovering from the deflection of the stabilizer 26 may act on a bottom surface 30b of the mounting area 30. Thus, rattling caused by unwanted movement of the attachment section 20 with respect to the cover 2 may be suppressed. Further, a tool insertion hole 26a allowing insertion of a tool (not shown) to rotate the clip 1 is located in the lower surface of the stabilizer 26.

(27) A close-up view of the mounting area 30, to which the attachment section 20 of the clip 1 may attach, is shown in further detail in FIG. 4 The mounting area 30 has a guide groove 32 and a circular mounting hole 34. The mounting hole 34 may be formed toward the bottom of the guide groove 32. The mounting hole 34 is slightly larger than the pillar 22 of the clip 1. The mounting area 30 has a first recess 34a ahead of the guide groove 32 with the mounting hole 34. The mounting area 30 has a second recess 34b and a third recess 34c at positions generally perpendicular to the guide groove 32 and the first recess 34a.

(28) The mounting area 30 has a pair of ribs 36 near the inlet of the guide groove 32. The distance between the pair of ribs 36 is slightly larger than the distance between the edges of the guide groove 32 and is also smaller than the longitudinal edge length of the base plate 12 of the clip 1. As a result, the attachment section 20 of the clip 1 can only be received by the mounting area 30 of the cover 2 in a predetermined direction (i.e., in the longitudinal direction of the base plate 12). When the attachment section 20 is attached to the mounting area 30, the clip 1 may be oriented to position the pair of elastic claws 14a to receive the opposing longitudinal edges of the clip hole 40 of the inner panel 3.

(29) When an attempt is made to attach the attachment section 20 in a direction perpendicular to a linear attachment direction toward the mounting hole 34, the base plate 12 of the clip 1 may contact and/or interfere with the pair of ribs 36. As a result, the attachment section 20 may not be able to attach to the mounting area 30.

(30) As shown in FIG. 10, each rib 36 has a gently sloped wall 36a on the side where the attachment section 20 of the clip 1 is received, and an erect wall 36b on the opposite side thereof. Thus, the detachment prevention member 12a of the base plate 12 may maneuver around and/or over the ribs 36 as needed to engage the attachment section 20 to the mounting area 30.

(31) Returning now to FIG. 1, an elongated-hole-like clip hole 40 formed in the inner panel 3 is shown. The anchor portion 10 of the clip 1 attached to the cover 2 is inserted into the clip hole 40 to attach the cover 2 to the inner panel 3. The length of the short edges of the clip hole 40 is set such that the pair of elastic claws 14a of the anchor portion 10 are engaged with the longitudinal edges.

(32) The length of the longitudinal edges of the clip hole 40 may be configured such that, when the clip 1 is rotated approximately 90 degrees from, for example, an initial engaged position, the pair of elastic claws 14a is released from the longitudinal edges. Thus, the clip 1 may be disengaged and/or removed from the inner panel 3 upon rotation of the clip 1 approximately 90 degrees.

(33) Procedures for mounting the cover 2 to the inner panel 3 by the clip 1 will be described in detail with reference to FIGS. 1 and 5 to 17. As shown in FIG. 1, a worker may insert the pillar 22 of the clip 1 into the guide groove 32 of the cover 2 as also shown in FIGS. 5 and 6. As a result, the flange 24 and the elastic members 12b of the clip 1 pinch the mounting area 30.

(34) The pillar 22 shown in FIG. 6 is inserted into the guide groove 32 shown in FIG. 5 in the longitudinal direction of the base plate 12. When, as shown in FIGS. 7 and 8, the pillar 22 is inserted into the guide groove 32 in the shorter-side direction of the base plate 12, the base plate 12 may press against and thus interfere with the ribs 36 of the cover 2. Accordingly, the pillar 22 may not be inserted into the guide groove 32 along the shorter-side direction of the base plate 12. As a result, erroneous attachment of the clip 1 to the cover 2 may be avoided.

(35) When the clip 1 is inserted into mounting hole 34 as shown in FIG. 5, the detachment prevention members 12a of the clip 1 may maneuver around the ribs 36 by guiding along the sloped walls 36a as shown in FIGS. 9 and 10. Upon further insertion of the clip 1 as described here, the pillar 22 of the clip 1 may reach the mounting hole 34 of the clip 1 as shown in FIGS. 11 and 12. As a result, the attachment section 20 of the clip 1 is attached to the mounting area 30 of the cover 2.

(36) As shown in FIGS. 11 and 12, the elastic members 12b of the clip 1 may be guided and/or deflected by the surface 30a of the mounting area 30 of the cover 2. Thus, unwanted detachment of the attachment section 20 from the mounting area 30 may be suppressed. The stabilizer 26 of the clip 1 may compress against the bottom surface 30b of the cover 2. Thus, unwanted rattling of the attachment section 20 with respect to the mounting area 30 may be suppressed.

(37) As shown in FIGS. 11 and 12, when the attachment section 20 is detached from the mounting area 30 by an external force, the detachment prevention members 12a of the clip 1 may press against and interfere with the erect walls 36b of the ribs 36 of the cover 2 as shown in FIGS. 13 and 14. Thus, unwanted detachment of the attachment section 20 from the mounting portion area 30 of the cover 2 may be prevented.

(38) As shown in FIGS. 14 and 15, the anchor portion 10 of the clip 1 inserts into the clip hole 40 of the inner panel 3 (also shown in FIGS. 16 and 17). The pair of elastic claws 14a engage with both of the longitudinal edges of the clip hole 40. As a result, the inner panel 3 may be attached to the cover 2 by the clip 1. In detail, the protrusions 12c of the clip 1 may enter the guide groove 32 and the first recess 34a.

(39) Next, methods for removing the cover 2 from the inner panel 3 will be described in further detail. First, referring generally to FIGS. 3 and 12, a tool (not shown in the FIGS.) may be inserted into the tool insertion hole 26a of the clip 1 from the through-hole 30c of the cover 2. The clip 1 may be rotated approximately 90 degrees relative to the clip hole 40 by the tool. As a result, as shown in FIGS. 18 and 19, the pair of elastic claws 14a of the anchor portion 10 may release from the inner panel 3. Thus, the anchor portion 10 may be drawn out of the clip hole 40 to allow for the removal of the cover 2 from the inner panel 3.

(40) As shown in FIG. 20, with the rotation of the clip 1, the protrusions 12c move from the guide groove 32 and the first recess 34a to the second recess 34b and the third recess 34c. Thus, after leaving the guide groove 32 and the first recess 34a, the protrusions 12c get over the surface 30a of the mounting area 30 to enter the second recess 34b and the third recess 34c.

(41) In order for the clip 1 to freely rotate, the protrusions 12c must maneuver around and/or over the surface of the mounting area 30. Thus, idling, vibration and/or other unwanted movement of the clip 1 may be prevented. The protrusions 12c maneuver around and/or over the surface of the mounting area 30 to enter the second recess 34b and the third recess 34c, respectively. Further, as a result of that described above, the clip 1 may rotate crisply and/or responsively by approximately 90 degrees.

(42) The clip hole 40 of the inner panel 3 may be configured as an elongated hole. Thus, the pair of elastic claws 14a may be released from engagement with the longitudinal edges upon rotation of the clip 1 by approximately 90 degrees with respect to the clip hole 40. Also, the force needed to remove the clip 1 from the inner panel 3 as disclosed in the prior art may be reduced. The mounting area 30 may include the pair of ribs 36 in a vicinity of the inlet of the guide groove 32. The distance between the pair of ribs 36 is slightly longer than the short edges of the base plate 12 of the clip 1. Accordingly, the base plate 12 of the clip 1 may contact, block and/or otherwise interfere with the ribs 36 of the cover 2 when an attempt is made to insert the pillar 22 of the clip 1 into the guide groove 32 over the cover 2 in a direction orthogonal to the guide groove 32. Thus, it is possible to prevent erroneous attachment of the clip 1 with respect to the cover 2.

(43) The detachment prevention members 12a are formed at and extend from both longitudinal edges of the base plate 12. When the attachment section 20 receives an external force to detach from the mounting area 30, the detachment prevention members 12a may block and/or otherwise interfere with the erect walls 36b of the ribs 36 of the cover 2. Thus, the attachment section 20 may be prevented from detachment from the mounting area 30 of the cover 2.

(44) Each elastic member 12b has a surface facing toward the base plate 12 and a surface opposite the same. The protrusion 12c is formed on the opposite surface. In detail, the protrusions 12c may enter the guide groove 32 and the first recess 34a when the cover 2 is attached to the inner panel 3 by the clip 1. Thus, idling and/or other unwanted movement of the clip 1 attached to the cover 2 may be prevented. Further, the clip 1 may be prevented from detachment from the cover 2 due to vibration during, for example, transportation.

(45) The mounting area 30 has the second recess 34b and the third recess 34c positioned orthogonal to the direction of the guide groove 32 and the first recess 34a. In detail, the protrusions 12c of the clip 1 move from the guide groove 32 and the first recess 34a to the second recess 34b and the third recess 34c, respectively, upon rotation of the cover 2 from the inner panel 3. After leaving the guide groove 32 and the first recess 34a, the protrusions 12c may maneuver around and/or over a surface 3a (not shown in the FIGS.) of the mounting area 30 to enter into the second recess 34b and the third recess 34c. Further, and as discussed earlier, the protrusions 12c may enter the second recess 34b and the third recess 34c to provide an operator and/or a worker can be taught and/or crisp feel indicating rotation of the clip 1 by approximately 90 degrees relative to the clip hole 40.

(46) While the embodiments of invention have been described with reference to specific configurations, it will be apparent to those skilled in the art that many alternatives, modifications and variations may be made without departing from the scope of the present invention. Accordingly, embodiments of the present invention are intended to embrace all such alternatives, modifications and variations that may fall within the spirit and scope of the appended claims. Embodiments of the present invention should not be limited to the representative configurations, but may be modified, for example, as described below.

(47) For instance, the mounting member may be, as described in the embodiments above, the cover 2 that is an interior component of a vehicle door. Further, and as described earlier, the panel may be the inner panel 3 of a vehicle door. However, in alternative and/or additional embodiments, the cover may be one selected from various other types of mounting members and/or covers, and the panel may be one selected from various other types of panels.

(48) As described above, the cover 2 may have one mounting area 30 for mounting the clip 1. In alternative and/or additional embodiments, the cover 2 may have a plurality of, e.g., two or more, mounting areas 30.
