Description

[Technical Field]

[0001] The present invention relates to a fastener for a vehicle door operating device. [Background technology]

[0002] Patent Document 1 discloses a handle assembly for a vehicle door, including a handle and a body supporting the handle. This handle assembly is attached to the door panel so that the surface of the handle is flush with the surface of the door panel to improve aesthetics. More specifically, the handle assembly is fixed to a mounting bracket disposed inside the door panel with fasteners such as bolts and nuts. It is believed that the bolt is inserted into a bolt-insertion hole that penetrates the body and is threaded into a nut attached to the mounting bracket. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5739998 Summary of the Invention [Problem to be solved by the invention]

[0004] It is possible that the relative positional relationship between the bolt insertion holes and the mounting bracket may deviate from the ideal due to assembly errors in the handle assembly, door assembly errors, or both. In this case, the surface of the handle and the surface of the door panel will no longer be flush, resulting in a poor aesthetic appearance. If dimensional accuracy is increased to avoid this, productivity of the handle assembly and vehicle will decrease.

[0005] An object of the present invention is to achieve both improved aesthetics and improved productivity. [Means for solving the problem]

[0006] One aspect of the present invention provides a fastener for a vehicle door operating device used to secure a door operating device for opening and closing a door of a vehicle with a bolt to the door, the fastener comprising: a retaining member positioned at one end opening of a through hole provided in the door operating device; a first fastener held by the retaining member and positioned within the through hole; a second fastener engaging with the first fastener so as to be displaceable in the axial direction; and a bolt insertion hole that passes through the retaining member, the first fastener, and the second fastener and through which the bolt is inserted.

[0007] In the above configuration, the fastener is not a bolt or nut, but forms a bolt insertion hole through which the bolt is inserted. The axial dimension of this fastener (i.e., the length of the bolt insertion hole) can be adjusted by displacing the second fastener relative to the first fastener. Therefore, even if there is an assembly error in the door operating device or the door, the error can be absorbed by displacing the second fastener, and the door operating device can be assembled to the door. The aesthetic appearance of the door operating device can be maintained without requiring high dimensional accuracy. [Effects of the Invention]

[0008] According to the present invention, it is possible to improve both aesthetic appearance and productivity. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments will be described with reference to the drawings. Note that the same or corresponding elements are designated by the same reference numerals throughout the drawings, and detailed descriptions thereof will be omitted.

[0011] 1, 2, and 5, a fastener 25 according to this embodiment is used to secure a door operating device for opening and closing a vehicle door 1 to the door 1 with a bolt 23. Examples of such a vehicle door operating device include a door handle device 10, a door latch device, and a door lock device. The door handle device 10 includes an outer handle device provided on the vehicle exterior side in the thickness direction of the door 1, and an inner handle device provided on the vehicle interior side in the thickness direction of the door 1.

[0012] The fastener 25 has the function of absorbing deviations in the relative position between the door operating device and the door 1 due to assembly errors, etc. Even if a positional deviation occurs (in other words, even if the dimensional precision of the door 1 or the door operating device is not particularly high), the door operating device can be fixed to the door 1 under ideal placement conditions.

[0013] The door handle device 10, particularly the outer handle device, forms the exterior of the vehicle, and its positional accuracy can significantly affect the aesthetics. Therefore, the fastener 25 is suitable for use with the door handle device 10, among other door operating devices. By using the fastener 25, the door handle device 10 can be assembled to the door 1 with reduced or eliminated misalignment, improving the aesthetics of the vehicle. In the case where the door handle device 10 is a so-called flush surface type in which the outer surface of the handle lever 12 is flush with the outer surface of the door 1, eliminating misalignment further enhances the aesthetics.

[0014] The fastener 25 according to the embodiment will be described below, taking as an example a case where the fastener 25 is applied to a flush surface type door handle device 10 (outer handle device).

[0015] Referring to Fig. 1, a vehicle door 1 is composed of a plurality of panel members. The panel members include an outer panel 2 shown in the figure, an inner panel (not shown) disposed on the vehicle interior side of the outer panel 2, and a reinforcing panel 3 (see Fig. 7) disposed between the outer panel 2 and the inner panel. The outer surface of the outer panel 2 forms the exterior appearance of the vehicle. Door operating devices, including a door handle device 10, are housed in the space formed between the outer panel 2 and the inner panel.

[0016] The door handle device 10 is attached to the rear side of the outer panel 2, and the outer surface of the handle lever 12 is exposed to the outside of the vehicle through an opening 2a formed in the outer panel 2. For example, when no external force, such as a user's operating force, is applied to the handle lever 12, the outer surface of the handle lever 12 is flush with the outer surface of the outer panel 2.

[0017] 2, the door handle device 10 includes a support case 11. The handle lever 12 is rotatably supported by the support case 11 while being accommodated in a recess 11a provided in the support case 11. The support case 11 has a plurality of mounting flanges 11b that protrude outward from the recess 11a. When the door handle device 10 is fixed to the door 1, the mounting flanges 11b are located outside the opening 2a and on the rear side of the outer panel 2.

[0018] Each mounting flange 11b is provided with a through hole 21. Generally, this through hole 21 functions as a bolt insertion hole through which a bolt for fixing the door handle device 10 to the door 1 (see FIG. 1) is inserted. In this embodiment, a fastener 25 is attached to each through hole 21 to form a bolt insertion hole 22. In the illustrated example, there are three mounting flanges 11b and three through holes 21, and the door handle device 10 is fastened to the door 1 at three points, but this number is not particularly limited.

[0019] 2 and 5, the through hole 21 extends in the thickness direction of the mounting flange 11b. One end opening 21a of the through hole 21 opens to the end surface of the mounting flange 11b facing the vehicle interior side, and the other end opening 21b of the through hole 21 opens to the end surface of the mounting flange 11b facing the vehicle exterior side. The inner circumferential surface 21c of the through hole 21 is circular when viewed in the axial direction and extends in the axial direction between the one end opening 21a and the other end opening 21b. The other end opening 21b has a diameter slightly larger than that of the one end opening 21a. The inner circumferential surface 21c includes a small diameter portion connected to the one end opening 21a and a large diameter portion connected to the other end opening 21b. A stepped surface 21d having an annular shape when viewed in the axial direction is provided inside the through hole 21. The stepped surface 21d connects the large diameter portion and the small diameter portion in a direction perpendicular to the axial direction and faces the vehicle exterior side. The large diameter portion is extremely shorter in the axial direction than the small diameter portion, and step surface 21d is located near other-end opening 21b. Hereinafter, when the term "inner peripheral surface 21c" is used without any special specification, it refers to the small diameter portion that is closer to the vehicle interior than step surface 21d.

[0020] 3 and 4, fastener 25 includes a retaining member 30, a first fastener 40, and a second fastener 50. Retaining member 30, first fastener 40, and second fastener 50 are arranged in this order from the vehicle interior side and are coaxial with one another. Fastener 25 forms bolt insertion hole 22. Bolt insertion hole 22 passes through retaining member 30, first fastener 40, and second fastener 50.

[0021] The retaining member 30 is disk-shaped and has a circular through-hole 31 in the center. A plurality of locking claws 32 and a plurality of elastic deformation pieces 33 are provided on the end surface of the retaining member 30 facing the vehicle exterior. The end surface of the retaining member 30 faces the vehicle exterior and abuts against the end surface of the mounting flange 11b facing the vehicle interior.

[0022] The multiple locking claws 32 protrude in the axial direction from the periphery of the through hole 31 and are arranged at equal intervals in the circumferential direction. The multiple elastic deformation pieces 33 are similarly arranged. The multiple locking claws 32 and the multiple elastic deformation pieces 33 are arranged alternately at equal intervals in the circumferential direction. In the illustrated example, there are three locking claws 32 and three elastic deformation pieces 33, and the locking claws 32 and the elastic deformation pieces 33 are arranged alternately at 60-degree intervals, but the number is not particularly limited.

[0023] Each locking claw 32 extends parallel to the axial direction from the end face of the holding member 30, and is bent at its tip toward the radially inner periphery. Each elastically deformable piece 33 extends axially from the end face of the holding member 30, bulging outward in the radial direction. The elastically deformable pieces 33 are curved so that the inclination toward the radially outer periphery becomes gentler as they move away from the end face. The tips of the elastically deformable pieces 33 are directed approximately parallel to the axial direction. The elastically deformable pieces 33 extend in a cantilevered manner from the end face of the holding member 30. The tips (free ends) of the elastically deformable pieces 33 are flexible and deformable in the radial direction (particularly toward the radially inner periphery). In the illustrated example, the protrusion amount of the elastically deformable pieces 33 is greater than the protrusion amount of the locking claws 32, and the tips of the elastically deformable pieces 33 are located on the vehicle exterior side relative to the tips of the locking claws 32. However, this is just one example, and the protruding amount of the elastic deformation piece 33 may be the same as or smaller than the protruding amount of the locking claw 32.

[0024] The first fastener 40 is cylindrical overall. The first fastener 40 has a first cylindrical portion 42, an intermediate flange 43, and a notch 44. The first cylindrical portion 42 forms a first internal space 41 that is open on both axial sides. The first internal space 41 is defined by an inner circumferential surface 42b of the first cylindrical portion 42. Both the outer circumferential surface 42a and the inner circumferential surface 42b of the first cylindrical portion 42 have a circular cross section. An internal thread 45 is formed on the inner circumferential surface 42b. The intermediate flange 43 has an annular shape when viewed in the axial direction, and protrudes radially from the outer circumferential surface 42a at the tip end (the end on the vehicle exterior) of the first cylindrical portion 42. The notch 44 is formed in the outer circumferential surface 42a at the base end of the first cylindrical portion 42. In this example, the notch 44 is groove-shaped and extends endlessly in the circumferential direction.

[0025] The second fastener 50 is also cylindrical overall. The second fastener 50 has a second cylindrical portion 52 and a tip flange 53, and the second cylindrical portion 52 forms a second internal space 51 that is open on both axial sides. The second internal space 51 is defined by an inner circumferential surface 52b of the second cylindrical portion 52. Both the outer circumferential surface 52a and the inner circumferential surface 52b of the second cylindrical portion 52 have a circular cross section. A male thread 55 that can be threadably engaged with the female thread 45 of the first fastener 40 is formed on the outer circumferential surface 52a. The tip flange 53 is hexagonal when viewed in the axial direction, and protrudes radially from the outer circumferential surface 52a of the tip end (the end on the vehicle exterior) of the second cylindrical portion 52.

[0026] Next, the fastener 25 and its surrounding structure will be described in more detail with reference to FIGS. 5 and 6 along the steps for fixing the door handle device 10 to the door 1. FIG.

[0027] 5 and 6, a mount 4 is provided integrally with the outer panel 2 on the rear surface of the outer panel 2, and a bolt 23 is welded to the mount 4 and extends from the mount 4 toward the vehicle interior. In this case, the bolt 23 is inserted into a bolt insertion hole 22 of a fastener 25 attached to the through hole 21, protrudes from the rear surface side of the mounting flange 11b, and is screwed into a nut 24. In this way, the support case 11, and therefore the door handle device 10, are fixed to the door 1 by the bolt 23.

[0028] In this fixing operation, first, the holding member 30 is attached to the through-hole 21. At this time, the locking claw 32 and the elastically deformable piece 33 are inserted into the through-hole 21 via the one-end opening 21a.

[0029] The outer diameter of the retaining member 30 is larger than the diameter of the one-end opening 21a of the through-hole 21. The end face of the retaining member 30 does not pass through the through-hole 21, but abuts against the end face of the mounting flange 11b on the vehicle interior side. This positions the retaining member 30 in the axial direction with respect to the one-end opening 21a. The inner diameter of the retaining member 30 (the diameter of the through-hole 31) is smaller than the diameter of the one-end opening 21a.

[0030] Not only the radial distance from the center of through hole 21 to the tip of locking claw 32, but also the radial distance to the base of locking claw 32 is smaller than the diameter of one-end opening 21 a. Therefore, locking claw 32 can easily enter through hole 21 through one-end opening 21 a.

[0031] On the other hand, the radial distance from the center of the through hole 21 to the tip of the elastically deformable piece 33 is larger than the diameter of the one-end opening 21a. Therefore, when attaching the retaining member 30 to the through hole 21, the tip of the elastically deformable piece 33 is bent radially inward, and the elastically deformable piece 33 is inserted into the through hole 21 via the one-end opening. The radial distance from the center of the through hole 21 to the elastically deformable piece 33 becomes smaller toward the base. Therefore, once the tip is inserted into the through hole 21, the elastically deformable piece 33 advances into the through hole 21 simply by pushing the retaining member 30 toward the vehicle exterior. The radial distance from the center of the through hole 21 to the base of the elastically deformable piece 33 is smaller than the diameter of the one-end opening 21a. Therefore, the tip of the elastically deformable piece 33 bends radially toward the center, applying an elastic force corresponding to the amount of bending to the inner circumferential surface 21c of the through hole 21.

[0032] Next, the first fastener 40 is attached to the through hole 21. The base end of the first cylindrical portion 42 is inserted into the through hole 21 via the other end opening 21b. As the insertion progresses, the tip of the locking claw 32 rides up onto the outer circumferential surface 42a of the first cylindrical portion 42 and fits into the notch 44 to be locked. As a result, the first fastener 40 is held by the retaining member 30 and positioned within the through hole 21. At the same time as being held by the locking claw 32, the intermediate flange 43 abuts against the stepped surface 21d. As a result, the first fastener 40 is positioned axially relative to the through hole 21. The end face of the intermediate flange 43 is approximately flush with the end face of the mounting flange 11b on the vehicle exterior side.

[0033] Next, the second fastener 50 is engaged with the first fastener 40. The base end of the second cylindrical portion 52 is screwed into the first internal space 41 from the outside of the vehicle. The second fastener 50 engages with the first fastener 40 as the male thread 55 threads into the female thread 45. The axial position of the second fastener 50 relative to the first fastener 40 is set according to the amount of screwing (the amount of rotation of the second fastener 50). In this way, the second fastener 50 engages with the first fastener 40 so as to be displaceable in the axial direction relative to the first fastener 40. Note that when screwing, the first fastener 40 or the retaining member 30 is gripped so as to prevent the first fastener 40 from rotating.

[0034] Hereinafter, the axial distance from the intermediate flange 43 of the first fastener 40 to the tip flange 53 of the second fastener 50 will be referred to as the "stroke amount S." By applying a threaded pair to the first fastener 40 and the second fastener 50, the stroke amount S changes continuously according to the amount of screwing, and once the screwing is stopped, the stroke amount S remains unchanged and fixed even if an axial external force is applied to the first fastener 40 and the second fastener 50.

[0035] The stroke amount S can be reduced to zero. That is, the second fastener 50 can be screwed into the first fastener 40 until the tip flange 53 abuts against the intermediate flange 43. The second cylindrical portion 52 is shorter than the first cylindrical portion 42. Therefore, when the stroke amount S is zero, the second cylindrical portion 52 does not protrude toward the vehicle interior relative to the first fastener 40 and the retaining member 30, and is housed in the first internal space 41.

[0036] By assembling the fastener 25 in this manner, the through-hole 31 of the retaining member 30, the first internal space 41 of the first fastener 40, and the second internal space 51 of the second fastener 50 become coaxial and communicate with each other. As a result, the bolt insertion hole 22 is formed so as to penetrate the entire fastener 25.

[0037] Then, with the tip flange 53 facing the back surface of the outer panel 2, the bolt 23 is inserted into the bolt insertion hole 22, and the door handle device 10 is brought closer to the back surface of the outer panel 2. The tip flange 53 abuts against the back surface of the head of the bolt 23, and is thereby supported by the outer panel 2 of the door 1 via the bolt 23 and the mount 4.

[0038] Due to assembly errors, the relative positions of the centers of the through-holes 21 and the bolts 23 may deviate from ideal placement conditions. Positional deviations can occur in the axial direction and in the direction perpendicular to the axis.

[0039] If misalignment occurs in the axial direction, the amount by which the second fastener 50 is threaded into the first fastener 40, i.e., the stroke amount S, is adjusted. By changing the stroke amount S, the fastener 25 absorbs the misalignment in the axial direction. This allows the relative position in the axial direction between the center of the through hole 21 and the center of the bolt 23 to be ideal.

[0040] If a positional deviation occurs in the direction perpendicular to the axis, the fastener 25 as a whole is displaced in the direction perpendicular to the axis relative to the through hole 21.

[0041] In this regard, in an unloaded state, the retaining member 30 can be positioned coaxially with the through hole 21 due to the balance of the elastic forces of the three elastic deformation pieces 33 arranged at equal intervals in the circumferential direction. By applying an external force to the fastener 25 against this balance of elastic forces, the retaining member 30 can be displaced in the direction perpendicular to the axis within the through hole 21. In this way, the retaining member 30 is positioned with respect to the through hole 21 in the axial direction, while being elastically supported so as to be displaceable relative to the through hole 21 in the direction perpendicular to the axis. The first fastener 40 held by the retaining member 30 and the second fastener 50 engaged with the first fastener 40 are also elastically supported via the elastic deformation pieces 33 so as to be displaceable in the radial direction relative to the through hole 21.

[0042] Therefore, when the bolt 23 is inserted into the bolt insertion hole 22, the load acting on the fastener 25 due to misalignment in the direction perpendicular to the axis causes the fastener 25 to automatically displace in the direction perpendicular to the axis within the through hole 21, absorbing the misalignment. This makes it possible to achieve an ideal relative position in the axial direction between the center of the through hole 21 and the center of the bolt 23.

[0043] The bolt 23 protrudes toward the vehicle interior side from the bolt insertion hole 22. A nut 24 is threaded onto the protruding portion of the bolt 23 and tightened onto the end surface of the retaining member 30 facing toward the vehicle interior side. This fixes the door handle device 10 to the door 1.

[0044] As described above, the fastener 25 comprises a retaining member 30 positioned at one end opening 21a of the through hole 21 provided in the door handle device 10, a first fastener 40 held by the retaining member 30 and positioned within the through hole 21, a second fastener 50 that engages with the first fastener 40 so as to be displaceable in the axial direction, and a bolt insertion hole 22 that passes through the retaining member 30, the first fastener 40, and the second fastener 50 and through which the bolt 23 is inserted.

[0045] According to the above configuration, the axial dimension of the fastener 25 (i.e., the length of the bolt insertion hole 22) can be adjusted by displacing the second fastener 50 relative to the first fastener 40. Therefore, even if there is an assembly error in the door handle device 10 or the door 1, the error can be absorbed by displacing the second fastener 50, and the door handle device 10 can then be assembled to the door 1. The aesthetic appearance can be maintained without increasing the dimensional accuracy of the door handle device 10 and the door 1, and both improved aesthetics and improved productivity can be achieved.

[0046] The first fastener 40 and the second fastener 50 are cylindrical, with an internal thread 45 provided on the inner peripheral surface 42b of the first fastener 40 and an external thread 55 that can be threaded into the internal thread 45 provided on the outer peripheral surface 52a of the second fastener 50, and the position of the second fastener 50 relative to the first fastener 40 is set according to the amount of threading of the second fastener 50 into the first fastener 40. In this way, by using a threaded pair, fine position adjustment is possible. Furthermore, undesired changes to the adjusted position can be prevented.

[0047] The first fastener 40 has a notch 44 on the outer peripheral surface 42a of its base end, and the retaining member 30 has a locking claw 32 that locks into the notch 44. As a result, the first fastener 40 is held by the retaining member 30 simply by bringing the first fastener 40 axially closer to the retaining member 30, facilitating assembly of the fastener 25. In particular, when the retaining member 30 and the first fastener 40 are inserted into the through-hole 21 from opposite sides, employing such a structure is particularly beneficial in terms of ensuring ease of assembly.

[0048] A tip flange 53 that is supported by the door 1 is provided at the tip of the second fastener 50. By adjusting the stroke amount S, the tip flange 53 that abuts against a member on the door 1 side can be directly displaced, making it easy to eliminate axial positional misalignment.

[0049] The retaining member 30 is capable of radially flexibly deforming, and has a plurality of elastically deforming pieces 33 interposed between the inner peripheral surface 21c of the through hole 21 and the outer peripheral surface 42a of the first fastener 40, with the elastically deforming pieces 33 spaced apart in the circumferential direction. The first fastener 40 is elastically supported relative to the through hole 21 via the elastically deforming pieces 33 so as to be displaceable in the radial direction. This makes it possible to absorb positional deviations in the direction perpendicular to the axis. This achieves both improved aesthetics and improved productivity.

[0050] Although the embodiments have been described above, the above configurations can be modified as appropriate within the scope of the present invention.

[0051] As shown in FIG. 7 , the fastening member (bolt 23 or nut 24) may be provided on a panel member other than the outer panel 2, and the panel member may be provided with a nut 24 instead of the bolt 23. In the illustrated example, the nut 24 is welded to the back surface of the reinforcing panel 3. In this case, the tip flange 53 abuts against the end surface of the nut 24 on the vehicle interior side. In this state, the bolt 23 is inserted into the bolt insertion hole 22 from the vehicle interior side. The bolt 23 protrudes toward the vehicle interior side relative to the second fastener 50 and is threaded into the nut 24, and the head of the bolt 23 is tightened against the end surface of the retaining member 30 on the vehicle interior side.

[0052] In this example, too, misalignment can be absorbed by adjusting the stroke amount S and displacing the fastener 25 in the direction perpendicular to the axis relative to the through-hole 21, allowing the door handle device 10 to be assembled to the door 1 in an ideal positional relationship. This allows for both improved aesthetics and improved productivity.

[0053] Although detailed illustration is omitted, the configuration for engaging the second fastener 50 with the first fastener 40 so that it can be displaced in the axial direction is not limited to a threaded pair. For example, the inner peripheral surface of the first fastener may be provided with multiple protrusions arranged in the axial direction, and the outer peripheral surface of the second fastener may be provided with a single recess that can engage with the protrusions. By selecting the protrusion to engage with the recess, the axial position of the second fastener relative to the first fastener can be adjusted. Note that the protrusion may be provided on the second fastener and the recess may be provided on the first fastener. There may also be a single protrusion and multiple recesses.

[0054] The fastener 25 may be applied not only to the door handle device 10 but also to other vehicle door operating devices, such as a door latch mechanism or a door lock mechanism. [Explanation of symbols]
