Description

SUN VISOR ATTACHMENT DEVICE TECHNICAL FIELD

[0001] The present invention relates to a sun visor attachment device for attaching a sun visor to an attachment target member. BACKGROUND ART

[0002] For example, a sun visor is rotatably attached to a driver seat or a front passenger seat of a vehicle via a shaft. In this case, a bracket that can support the shaft of the sun visor is attached, via a clip, to an attachment target member such as a ceiling wall above the driver seat or the front passenger seat.

[0003] For example, Patent Literature 1 described below describes an attachment structure for a clip in which a seat portion is provided on one side, a panel locking portion that engages with a panel member is provided on the other side, and the seat portion is fixed to an assembly member.

[0004] The assembly member includes a clip holder integrally provided on an attachment stem. The clip holder includes a base wall on which a locking protrusion is provided, and a pair of side walls having a substantially L-shaped frame shape and erected from the base wall. One side surface of the locking protrusion is an inclined surface inclined with respect to a plane direction of the base wall, and the other side surface thereof is a locking surface perpendicular to the plane direction of the base wall. On the other hand, the clip includes the panel locking portion, and the seat portion having a plate shape and connected to the panel locking portion. A locking claw that is locked to the locking protrusion of the clip holder is provided on a back side of the seat portion.

[0005] When the seat portion of the clip is inserted between the pair of side walls of the clip holder, the locking claw presses the inclined surface of the locking protrusion so that the clip is pushed in while the base wall is bent (see Fig. 4 in Patent Literature 1), and when the locking claw climbs over a top portion of the locking protrusion and reaches the locking surface, the base wall is elastically restored so that the locking claw and the locking surface are locked to each other (see Fig. 5 in Patent Literature 1). Therefore, the clip is attached to the clip holder. CITATION LIST PATENT LITERATURE

[0006] Patent Literature 1: JP2003-343526A SUMMARY OF INVENTION TECHNICAL PROBLEM

[0007] However, it may be desired to remove the clip from the bracket that supports the shaft of the sun visor due to maintenance, component replacement, or the like.

[0008] However, in the structure described in Patent Literature 1, even if the seat portion is attempted to be pulled out from the clip holder in a state where the clip is attached to the clip holder, the locking claw abuts against the locking surface of the locking protrusion so that the clip cannot be further pulled out, and the locking protrusion is a rigid body so that the locking protrusion itself cannot be bent and deformed. Therefore, it is difficult to remove the clip from the clip holder.

[0009] Therefore, an object of the present invention is to provide a sun visor attachment device in which a metal clip can be easily attached to and detached from a bracket that supports a sun visor. SOLUTION TO PROBLEM

[0010] In order to achieve the above object, the present invention provides a sun visor attachment device for attaching a sun visor to an attachment target member, and the sun visor attachment device includes: a bracket attached to the attachment target member and configured to support the sun visor; a metal clip mounted to the bracket; and a pin member assembled to the bracket. The metal clip includes: a base plate having a clip side insertion hole through which the pin member is inserted; a pair of flange portions extending from the base plate; and a pair of elastic engagement pieces that are erected from the base plate, that engage with a clip attachment hole formed in the attachment target member, and that are elastically deformable. The bracket includes a base portion disposed on a face side of the attachment target member, and a support portion and a clip mounting portion are provided on the base portion. The support portion is configured to support a shaft portion extending from a sun visor body, and the metal clip is mounted to the clip mounting portion. The clip mounting portion includes: a pedestal portion configured to support the base plate and formed with a bracket side insertion hole through which the pin member is inserted; and a pair of flange pressing portions provided on both sides of the pedestal portion and configured to press the pair of flange portions to prevent the metal clip from coming off from the pedestal portion in an insertion direction of the pin member. The metal clip is mounted to the clip mounting portion by sliding the base plate with respect to the pedestal portion in a direction orthogonal to the insertion direction of the pin member and pressing the pair of flange portions by the pair of flange pressing portions. The clip mounting portion further includes: an elastic coming-off prevention claw portion elastically deformable, and configured to abut against a side edge portion of the base plate on a side opposite to a sliding direction in a state where the metal clip is mounted, thereby preventing the metal clip from coming off toward the side opposite to the sliding direction; and a slide restriction portion configured to abut against a side edge portion of the base plate on a side in the sliding direction during sliding of the metal clip, thereby restricting movement of the metal clip in the sliding direction. The pin member is inserted between the pair of elastic engagement pieces through the bracket side insertion hole and the clip side insertion hole so as to restrict elastic deformation of the pair of elastic engagement pieces toward an inside of the clip attachment hole. ADVANTAGEOUS EFFECTS OF INVENTION

[0011] In the present invention, when the metal clip is to be mounted to the clip mounting portion, only by a simple work of sliding the base plate of the metal clip with respect to the pedestal portion in the direction orthogonal to the insertion direction of the pin member, the pair of flange portions can be pressed by the pair of flange pressing portions and the side edge portion of the metal clip on the side opposite to the sliding direction can be prevented from coming off by the elastic coming-off prevention claw portion, so that the metal clip can be easily mounted to the clip mounting portion. When the metal clip is to be removed from the clip mounting portion, the metal clip can be easily removed from the clip mounting portion only by a simple work of sliding the base plate of the metal clip toward the side opposite to the sliding direction during mounting of the clip in a state where the elastic coming-off prevention claw portion is elastically deformed so as not to abut against the side edge portion of the metal clip on the side opposite to the sliding direction. Thus, in the sun visor attachment device, the metal clip can be easily attached to and detached from the clip mounting portion of the bracket. BRIEF DESCRIPTION OF DRAWINGS

[0013] <Embodiment of Sun Visor Attachment Device> Hereafter, an embodiment of a sun visor attachment device according to the present invention will be described with reference to drawings.

[0014] As shown in Fig. 11, a sun visor attachment device 10 is a device for attaching a sun visor to an attachment target member 1 such as a ceiling panel of a vehicle, and includes a bracket 20 that is attached to the attachment target member 1 and supports the sun visor, a metal clip 50 mounted to the bracket 20, and a pin member 70 assembled to the bracket 20, as shown in Fig. 1.

[0015] As shown in Fig. 1, the attachment target member 1 is provided with a clip attachment hole 4 having a long hole shape, and a hook attachment hole 5 formed at a position adjacent to the clip attachment hole 4. Furthermore, as shown in Figs. 11 and 12, a cushion member 2 is disposed on a face side of the attachment target member 1. The cushion member 2 is formed with a bracket receiving hole 2a in which base end portions of a clip mounting portion 30, a support portion 23, and a hook 25 (which will be described later) of the bracket 20 are received.

[0016] The "face side" and a "face surface" of the attachment target member 1 mean a side and a surface facing an inside of a vehicle interior, and a "back side" and a "back surface" of the attachment target member 1 mean a side and a surface opposite to the face side and the face surface (a face side, a face surface, a back side, and a back surface also have the same meanings in the cushion member 2).

[0017] The bracket 20 includes a base portion 21 disposed on the face side of the attachment target member 1, the support portion 23 and the clip mounting portion 30 are provided on the base portion 21, the support portion 23 supports a shaft portion 7 of the sun visor, and the metal clip 50 is mounted to the clip mounting portion 30.

[0018] On the other hand, the metal clip 50 includes a base plate 51 having a clip side insertion hole 57 through which the pin member 70 is inserted, a pair of flange portions 53 and 53 extending from the base plate 51, and a pair of elastic engagement pieces 55 and 55 that are erected from the base plate 51, that engage with the clip attachment hole 4 formed in the attachment target member 1, and that are elastically deformable. As shown in Fig. 6, the metal clip 50 is mounted to the clip mounting portion 30 by sliding the base plate 51 with respect to a pedestal portion 31 (which will be described later) of the clip mounting portion 30 of the bracket 20 in a direction orthogonal to an insertion direction of the pin member 70 (see Figs. 1 and 5) (details will be described later). As shown in Fig. 1, a direction in which the base plate 51 is slid with respect to the pedestal portion 31, that is, a sliding direction of the base plate 51 with respect to the pedestal portion 31 is defined as a sliding direction S of the metal clip 50.

[0019] The pin member 70 includes a shaft portion 71 formed with a thread groove 71a in an outer periphery thereof and a head portion 73 having a circular flange shape and connected to one end portion of the shaft portion 71 in an axial direction. Furthermore, as shown in Fig. 11, the pin member 70 is inserted between the pair of elastic engagement pieces 55 through a bracket side insertion hole 32 and the clip side insertion hole 57 so as to restrict elastic deformation of the pair of elastic engagement pieces 55 and 55 toward an inside of the clip attachment hole 4.

[0020] Next, the bracket 20 will be specifically described.

[0021] The bracket 20 in the embodiment includes the base portion 21 that extends so as to be long in one direction. An outer peripheral edge portion 21a of the base portion 21 abuts against a fcae side peripheral edge of the bracket receiving hole 2a formed in the cushion member 2 (see Figs 11 and 12). As shown in Figs. 11 and 12, a counterbored portion 21b which has a circular recess shape and in which the head portion 73 of the pin member 70 is received is formed on an outer surface (surface separated from the attachment target member 1) side of the base portion 21 and at a position corresponding to the pedestal portion 31 which will be described later. A direction in which the base portion 21 extends is referred to as a "longitudinal direction X1", and a direction orthogonal to the longitudinal direction X1 is referred to as a "width direction Y1" (the same applies to a longitudinal direction and a width direction of each portion constituting the bracket 20). In the embodiment, the longitudinal direction X1 of the base portion 21 and the sliding direction S of the metal clip 50 are the same direction.

[0022] The clip mounting portion 30 is provided on one side portion of the base portion 21 in the longitudinal direction X1, that is, on a side portion of the base portion 21 on a side opposite to the sliding direction S of the metal clip 50. On the other hand, the support portion 23 is provided on the other side portion of the base portion 21 in the longitudinal direction X1, that is, on a side portion of the base portion 21 on a side in the sliding direction S of the metal clip 50 (side portion facing the sliding direction S). More specifically, the support portion 23 having a substantially cylindrical shape is erected from an inner surface (surface facing the attachment target member 1) of the base portion 21 at a position, close to the clip mounting portion 30, of the other side portion of the base portion 21 in the longitudinal direction X1. The shaft portion 7 of the sun visor is inserted into the support portion 23, so that the shaft portion 7 is rotatably supported (see Fig. 11).

[0023] The hook 25 extends toward an outer side of the base portion 21 from a portion of the other side portion of the base portion 21 in the longitudinal direction X1 which is located away from the clip mounting portion 30 and is adjacent to the support portion 23. As shown in Fig. 11, the hook 25 engages with a back side of the hook attachment hole 5

[0024] The clip mounting portion 30 includes the pedestal portion 31 that supports the base plate 51 of the metal clip 50 and is formed with the bracket side insertion hole 32 through which the pin member 70 is inserted and a pair of flange pressing portions 35 and 35 that are provided on both sides of the pedestal portion 31, and press the pair of flange portions 53 and 53 of the metal clip 50 to prevent the metal clip 50 from coming off from the pedestal portion 31 in an insertion direction F of the pin member 70. An "insertion direction of the pin member" in the present invention means the insertion direction of the pin member 70 through the bracket side insertion hole 32 and the clip side insertion hole 57.

[0025] The respective portions will be specifically described, and the pedestal portion 31 is a horizontally long and substantially rectangular pedestal which protrudes from the inner surface of the base portion 21 and in which a side in the longitudinal direction X1 is short and a side in the width direction Y1 of the base portion 21 is slightly long. The bracket side insertion hole 32 having a circular hole shape is formed in a central portion of the pedestal portion 31 in the width direction Y1. The bracket side insertion hole 32 communicates with the counterbored portion 21b formed in the base portion 21 (see Figs. 11 and 12), and the shaft portion 71 of the pin member 70 can be inserted into the bracket side insertion hole 32 from the outer surface side of the base portion 21 through the counterbored portion 21b.

[0026] Furthermore, both side surfaces 31a and 31a of the pedestal portion 31 are parallel to each other and extend along the sliding direction S of the metal clip 50. Cutout portions 33 and 33 are formed in both side portions, in the width direction Y1, of a front surface 31b (surface facing the sliding direction S of the metal clip 50) of the pedestal portion 31. Furthermore, as shown in Figs. 1 and 12, a ceiling surface 31c (surface that has a largest protruding height from the inner surface of the base portion 21 and faces the face surface of the attachment target member 1) of the pedestal portion 31 is formed to be lower than an outer surface 37a (which will be described later) of a pressing wall 37 of each flange pressing portion 35. The base plate 51 of the metal clip 50 is placed on the ceiling surface 31c so that the metal clip 50 is supported.

[0027] In the embodiment, in a state where the bracket 20 is attached to the attachment target member 1, the base plate 51 of the metal clip 50 is interposed between the ceiling surface 31c of the pedestal portion 31 and the face surface of the attachment target member 1 as shown in Fig. 12.

[0028] The pair of flange pressing portions 35 and 35 provided on the both sides of the pedestal portion 31 include a pair of side walls 36 and 36 that extend in the sliding direction S of the metal clip 50 and that are erected in parallel to each other from positions on the inner surface of the base portion 21 which are spaced apart from the both side surfaces 31a and 31a of the pedestal portion 31 by a predetermined distance and the pressing walls 37 and 37 that are bent, in directions of approaching each other, from tip ends of the pair of side walls 36 and 36 in an erection direction. Each pressing wall 37 is bent so as to be orthogonal to the respective side wall 36, and each flange pressing portion 35 has a substantially L- shaped frame shape.

[0029] The outer surface 37a (surface facing the face surface of the attachment target member 1) of the pressing wall 37 is higher than the ceiling surface 31c of the pedestal portion 31 in protruding position from the inner surface of the base portion 21 (see Fig. 12).

[0030] Furthermore, the pair of flange pressing portions 35 and 35 can abut against a face surface side of the attachment target member 1 (see Fig. 12). In the embodiment, in the state where the bracket 20 is attached to the attachment target member 1, the outer surface 37a of the pressing wall 37 of each flange pressing portion 35 abuts against the face surface of the attachment target member 1.

[0031] The metal clip 50 is mounted to the clip mounting portion 30 by sliding the base plate 51 with respect to the pedestal portion 31 in the direction orthogonal to the insertion direction of the pin member 70, that is, by sliding the base plate 51 with respect to the pedestal portion 31 in a direction indicated by the sliding direction S in Fig. 1, and pressing the pair of flange portions 53 and 53 by the pair of flange pressing portions 35 and 35 (see Fig. 6).

[0032] A mounting process of the metal clip 50 to the clip mounting portion 30 will be described later, and as shown in Fig. 8, in a state where the metal clip 50 is mounted to the clip mounting portion 30, an inner surface 37b (surface on a side opposite to the outer surface 37a) of each pressing wall 37 is disposed to face the respective flange portion 53 of the metal clip 50, thereby pressing (abutting against) the flange portion 53. That is, the pair of flange pressing portions 35 and 35 serve as a guide during slide mounting of the metal clip 50 to the pedestal portion 31, and serve to prevent the metal clip 50 from coming off from the pedestal portion 31 in the insertion direction F of the pin member 70 and hold the metal clip 50 (that is, to prevent the metal clip 50 from coming off from the pedestal portion 31 toward a side in the insertion direction F of the pin member 70 and hold the metal clip 50 so as not to further move the metal clip 50). Movement of the metal clip 50 toward a side opposite to the insertion direction F of the pin member 70 is restricted by the pedestal portion 31 of the bracket 20.

[0033] Furthermore, the clip mounting portion 30 includes elastic coming-off prevention claw portions 40 that are elastically deformable, and can abut against side edge portions 61a (side edge portions 61a of first abutment portions 61 shown in Fig. 4A) of the base plate 51 on a side opposite to the sliding direction S of the metal clip 50 in the state where the metal clip 50 is mounted, thereby preventing the metal clip 50 from coming off toward the side opposite to the sliding direction S and a slide restriction portion 45 that can abut against side edge portions 62a (side edge portions 62a of second abutment portions 62 shown in Fig. 4A) of the base plate 51 on a side in the sliding direction S of the metal clip 50 during sliding of the metal clip 50, thereby restricting movement of the metal clip 50 in the sliding direction S.

[0034] More specifically, in the embodiment, the pair of elastic coming-off prevention claw portions 40 and 40 are provided in the pair of cutout portions 33 and 33 formed in the pedestal portion 31. Each elastic coming-off prevention claw portion 40 includes an extending piece 41 having a thin plate shape and extending from a front surface (surface facing the sliding direction S of the metal clip 50) side of the respective cutout portion 33 and a protrusion 43 protruding, in a direction of being separated from the inner surface of the base portion 21 (upward), from a tip end portion of the extending piece 41 in an extending direction. As shown in Fig. 3B, the elastic coming-off prevention claw portion 40 is elastically deformable with a fixed end (base end of the extending piece 41) as a fulcrum so as to approach and move away from the inner surface of the base portion 21.

[0035] As shown in Fig. 1 and Fig. 3B, on one side surface (side surface on a side opposite to the sliding direction S of the metal clip 50) of the protrusion 43, a tapered surface 43a is formed which is inclined so as to be gradually increased in height from a tip end surface of the protrusion 43 toward a fixed end side of the elastic coming-off prevention claw portion 40.

[0036] As shown in Fig. 5, when the base plate 51 of the metal clip 50 is attempted to be inserted into the pedestal portion 31 in an inclined state and attempted to be slid in the sliding direction S in order to mount the metal clip 50 to the clip mounting portion 30, the tapered surface 43a makes it difficult for the respective side edge portion 62a or the like of the base plate 51 of the metal clip 50 on the side in the sliding direction S to abut against the protrusion 43 of the elastic coming-off prevention claw portion 40 (makes it difficult for the side edge portion 62a or the like to interfere with the protrusion 43), thereby improving workability in mounting the metal clip 50 to the clip mounting portion 30. During mounting of the metal clip 50 to the clip mounting portion 30, as shown in Fig. 5, when the metal clip 50 is slid in the sliding direction S in a state where the base plate 51 of the metal clip 50 is not greatly inclined with respect to the pedestal portion 31 and a back surface (surface facing the inner surface of the base portion 21 of the bracket 20) of the base plate 51 of the metal clip 50 is laid down so as to be close to the inner surface of the base portion 21, the side edge portion 62a or the like of the base plate 51 of the metal clip 50 on the side in the sliding direction S presses the tapered surface 43a of the protrusion 43, so that the elastic coming-off prevention claw portion 40 is elastically deformed in a direction of approaching the inner surface of the base portion 21 and thus the pair of flange portions 53 and 53 easily enter inner sides of the pair of flange pressing portions 35 and 35.

[0037] As shown in Fig. 3B, an abutment surface 43b orthogonal to the extending direction of the extending piece 41 is formed on the other side surface (side surface on a side in the sliding direction S of the metal clip 50) of the protrusion 43. The abutment surface 43b can abut against the side edge portion 61a of the base plate 51 of the metal clip 50 on the side opposite to the sliding direction S, and serves as a portion that prevents the metal clip 50 from coming off toward the side opposite to the sliding direction S.

[0038] Furthermore, the slide restriction portion 45 extends along the width direction Y1 of the base portion 21 from a position, adjacent to the support portion 23, of an intermediate position on the inner surface of the base portion 21 in the longitudinal direction X1. The other side portion of the pedestal portion 31 in the longitudinal direction X1 is connected to a surface, on a side opposite to the sliding direction S of the metal clip 50, of an intermediate portion of the slide restriction portion 45 in the width direction Y1. Furthermore, the other side portions of the flange pressing portions 35 in the longitudinal direction X1 are respectively connected to surfaces, on the side opposite to the sliding direction S of the metal clip 50, of both side portions of the slide restriction portion 45 in the width direction Xi.

[0039] When the base plate 51 of the metal clip 50 is slid in the sliding direction with respect to the pedestal portion 31, the side edge portions 62a of the second abutment portions 62 of the base plate 51 of the metal clip 50 located on the side in the sliding direction S abut against the slide restriction portion 45, so that further sliding of the metal clip 50 in the sliding direction S is restricted.

[0040] A ceiling surface 45a (surface that has a largest protruding height from the inner surface of the base portion 21 and faces the face surface of the attachment target member 1) of the slide restriction portion 45 is higher than the ceiling surface 31c of the pedestal portion 31 in protruding position from the inner surface of the base portion 21, and is continuous with and flush with the outer surface 37a of the pressing wall 37 of each flange pressing portion 35 without a step. Furthermore, as shown in Fig. 11, in the state where the bracket 20 is attached to the attachment target member 1, the ceiling surface 45a of the slide restriction portion 45 abuts against the face surface of the attachment target member 1.

[0041] Next, the metal clip 50 will be described in detail.

[0042] The metal clip 50 is formed by punching a metal plate having a predetermined thickness into a predetermined shape or bending the metal plate into a predetermined shape, and includes the base plate 51, the pair of flange portions 53 and 53, and the pair of elastic engagement pieces 55 and 55 erected from the base plate 51, as described in paragraph 0018.

[0043] Referring also to Fig. 4, the base plate 51 has a long plate shape that extends so as to be long in one direction. The base plate 51 is placed on the ceiling surface 31c of the pedestal portion 31 in the state where the metal clip 50 is mounted to the clip mounting portion 30 of the bracket 20, and is provided such that a surface thereof (which is a surface on one side in a thickness direction and a surface facing the face surface of the attachment target member 1) is at the same height as the outer surface 37a of the pressing wall 37 of each flange pressing portion 35 (see Figs. 8 and 12). Furthermore, the base plate 51 can abut against the face surface side of the attachment target member 1, that is, the surface of the base plate 51 can abut against the face surface of the attachment target member 1 (see Fig. 12). A direction in which the base plate 51 extends is referred to as a "longitudinal direction X2", and a direction orthogonal to the longitudinal direction X2 is referred to as a "width direction Y2" (the same applies to a longitudinal direction and a width direction of each portion constituting the metal clip 50). In the embodiment, the width direction Y2 of the base plate 51 is the same direction as the longitudinal direction X1 of the base portion 21 of the bracket 20 and the sliding direction S of the metal clip 50, and the longitudinal direction X2 of the base plate 51 is the same direction as the width direction Y1 of the base portion 21 of the bracket 20 (see Fig. 1).

[0044] A through hole having a circular hole shape is formed in a center of the base plate 51 in the longitudinal direction X2 and a center of the base plate 51 in the width direction Y2, and a cylindrical portion 56 having a cylindrical shape is erected from a surface side peripheral edge of the through hole. An internal space of the cylindrical portion 56 and the through hole formed in the base plate 51 constitute the clip side insertion hole 57 through which the shaft portion 71 of the pin member 70 is inserted (see (a) of Fig. 4). Furthermore, a thread groove 56a, which is screwed into the thread groove 71a formed in the outer periphery of the shaft portion 71 of the pin member 70, is formed in an inner periphery of the cylindrical portion 56 and an inner periphery of the through hole (see Figs. 11 and 12).

[0045] The pair of elastic engagement pieces 55 and 55 are erected from the base plate 51 so as to face each other in the sliding direction S of the base plate 51 with respect to the pedestal portion 31. In the embodiment, the pair of elastic engagement pieces 55 and 55 are erected from side edge portions extending along the longitudinal direction X2, that is, both side portions of the base plate 51 in the width direction Y2, so as to face each other in the sliding direction S of the base plate 51 with respect to the pedestal portion 31. Furthermore, the pair of elastic engagement pieces 55 and 55 are disposed to face each other such that a direction of elastic deformation (direction of bending deformation) thereof is along the sliding direction S of the metal clip 50.

[0046] As shown in Fig. 4C, the pair of elastic engagement pieces 55 and 55 include base end portions 58 and 58 that are erected obliquely outward from the side edge portions of the base plate 51 so as to slightly spread from each other, intermediate portions 59 and 59 that incline and extend obliquely inward from tip ends of the base end portions 58 and 58 in erection directions so as to approach each other, and tip end portions 60 and 60 that are formed by bending tip ends of the intermediate portions 59 and 59 in extending directions into a substantially U shape. As shown in Fig. 4B, a window portion 58a is formed by cutting away a middle of each base end portion 58 in a width direction, and the entire elastic engagement piece 55 is easily elastically deformed.

[0047] Furthermore, as shown in Fig. 4C, a distance W2 between outer surfaces of the base end portions 58 and 58 is slightly larger than a width, on a short axis side, of the clip attachment hole 4 having the long hole shape. Therefore, when the pair of elastic engagement pieces 55 and 55 are inserted into the clip attachment hole 4, the base end portions 58 and 58 are pressed against an inner periphery of the clip attachment hole 4, so that the pair of elastic engagement pieces 55 and 55 are inserted into the clip attachment hole 4 while being slightly elastically deformed toward an inside of the clip attachment hole 4, and the base end portions 58 and 58 temporarily engage with the inner periphery of the clip attachment hole 4. As a result, the bracket 20 can be temporarily held onto the clip attachment hole 4 via the metal clip 50 in a state before the pin member 70 is inserted through the bracket side insertion hole 32 and the clip side insertion hole 57.

[0048] As shown in Fig. 4C, a distance W1 between facing surfaces (inner surfaces) of the pair of tip end portions 60 and 60 is smaller than an outer diameter of the shaft portion 71 of the pin member 70. Therefore, when the shaft portion 71 of the pin member 70 is inserted between the pair of tip end portions 60 and 60, the tip end portions 60 and 60 are pressed by the shaft portion 71, so that the pair of elastic engagement pieces 55 and 55 are elastically deformed so as to be pushed away from each other as shown in Fig. 11. As a result, the base end portions 58 and 58 are expanded. Therefore, the base end portions 58 and 58 engage with the inner periphery of the clip attachment hole 4, and the bracket 20 is attached to the clip attachment hole 4 via the metal clip 50. In the state, the shaft portion 71 of the pin member 70 is inserted and disposed between the pair of elastic engagement pieces 55 and 55, so that elastic deformation of the pair of elastic engagement pieces 55 and 55 toward the inside of the clip attachment hole 4 is restricted. In the state, each elastic engagement piece 55 is elastically restored, so that the shaft portion 71 of the pin member 70 is interposed between the pair of tip end portions 60 and 60.

[0049] The base plate 51 of the metal clip 50 further includes the first abutment portions 61 that can abut against the elastic coming-off prevention claw portions 40 by protruding more toward the side opposite to the sliding direction S of the base plate 51 with respect to the pedestal portion 31 than the base end portions 58 and 58 of the pair of elastic engagement pieces 55 and 55 in the erection directions and the second abutment portions 62 that can abut against the slide restriction portion 45 by protruding more toward the side in the sliding direction S of the base plate 51 with respect to the pedestal portion 31 than the base end portions 58 and 58 of the pair of elastic engagement pieces 55 and 55 in the erection directions.

[0050] As shown in Fig. 4A, the pair of first abutment portions 61 and 61 protrude more toward the side opposite to the sliding direction S than the base end portion 58 of the respective elastic engagement piece 55 from one side portion of the base plate 51 in the width direction Y2, that is, one side portion on the side opposite to the sliding direction S of the metal clip 50, and both side portions of the base plate 51 in the longitudinal direction X2. Similarly, as shown in Fig. 4A, the pair of second abutment portions 62 and 62 protrude more toward the side in the sliding direction S than the base end portion 58 of the respective elastic engagement piece 55 from the other side portion of the base plate 51 in the width direction Y2, that is, the other side portion on the side in the sliding direction S of the metal clip 50, and the both side portions of the base plate 51 in the longitudinal direction X2. It can be said that each first abutment portion 61 and the respective second abutment portion 62 are disposed at the both side portions of the base plate 51 in the width direction Y2 so as to be at positions aligned with each other in the longitudinal direction X2 (see Fig. 4A).

[0051] As shown in Fig. 7, the side edge portion 61a of each first abutment portion 61 can abut against the abutment surface 43b of the protrusion 43 of the respective elastic coming-off prevention claw portion 40 provided in the clip mounting portion 30, so that the metal clip 50 is prevented from coming off toward the side opposite to the sliding direction S. As shown in Fig. 7, the side edge portion 62a of each second abutment portion 62 can abut against the slide restriction portion 45 provided in the clip mounting portion 30, so that sliding movement of the metal clip 50 in the sliding direction § is restricted. A maximum width W3 of the metal clip 50 in the width direction Y2 (which is a length from the side edge portion 61a of each first abutment portion 61 to the side edge portion 62a of the respective second abutment portion 62, and see (a) of Fig. 4) is smaller than a clip receiving width W4 of the clip mounting portion 30 (which is a length from the abutment surface 43b of the protrusion 43 of the elastic coming-off prevention claw portion 40 to the slide restriction portion 45, and see Fig. 2). As a result, in the state where the metal clip 50 is mounted to the clip mounting portion 30, as shown in Fig. 7, a gap is generated between the side edge portion 61a of the first abutment portion 61 and the abutment surface 43b of the respective protrusion 43, and a gap is also generated between the side edge portion 62a of the second abutment portion 62 and the slide restriction portion 45.

[0052] As shown in Fig. 4B, the pair of flange portions 53 and 53 are configured to extend at positions closer to the base portion 21 than the pedestal portion 31 due to a step 63 with respect to the base plate 51, so as to enter inner sides of the pair of flange pressing portions 35 and 35 as shown in Figs. 8 and 12.

[0053] More specifically, as shown in Figs. 4A and 4B, each flange portion 53 has a shape extending from the position closer to the base portion 21 of the bracket 20 than the pedestal portion 31 toward an outer side in the longitudinal direction X2 of the base plate 51 with respect to the base plate 51 via the step 63. The step 63 includes a mountain folding portion 63a that is a side portion of the base plate 51 in the longitudinal direction X2 and located at the same height as the base plate 51, an inclined portion 63b that is inclined obliquely outward from the mountain folding portion 63a toward a base portion 21 side of the bracket 20, and a valley folding portion 63c that is located at a tip end of the inclined portion 63b in an extending direction.

[0054] Each flange portion 53 is disposed to face the inner surface 37b of the pressing wall 37 of the respective flange pressing portion 35 of the bracket 20. In the embodiment, as shown in Figs. 8 and 12, in the state where the metal clip 50 is mounted to the clip mounting portion 30 of the bracket 20 and the base plate 51 is placed on the ceiling surface 31c of the pedestal portion 31, each flange portion 53 abuts against and engages with the inner surface 37b of the pressing wall 37 of the respective flange pressing portion 35. Furthermore, when the metal clip 50 is slid on the pedestal portion 31 along the sliding direction S in order to mount the metal clip 50 to the clip mounting portion 30, each flange portion 53 is in sliding contact with the inner surface 37b of the pressing wall 37 of the respective flange pressing portion 35, and serves as a guide for a sliding operation of the metal clip 50.

[0055] As shown in Figs. 8 and 12, the inclined portion 63b of the step 63 is disposed to face a side surface 37¢ of the pressing wall 37 of the respective flange pressing portion 35, and when the metal clip 50 is slid on the pedestal portion 31 or in the state where the metal clip 50 is mounted to the clip mounting portion 30, the metal clip 50 is less likely to be laterally shifted with respect to the pedestal portion 31 and a stable posture is maintained.

[0056] Both side edge portions of the step 63 and the flange portion 53 in the width direction Y2 respectively protrude toward the side opposite to the sliding direction S and the side in the sliding direction S similarly to the side edge portion of the first abutment portion 61 and the side edge portion of the second abutment portion 62, and constitute side edge portions that are continuous with and have no step with respect to the side edge portion 61a of the first abutment portion 61 and the side edge portion 62a of the second abutment portion 62.

[0057] The respective portions constituting the metal clip 50 described above, that is, the base plate 51, the flange portion 53, the elastic engagement piece 55, the cylindrical portion 56, the first abutment portion 61, the second abutment portion 62, and the like are integrally formed.

[0058] <Modification> For a bracket, a metal clip, and a pin member constituting the sun visor attachment device according to the present invention, respective portions (a base portion, a support portion, a clip mounting portion, a hook, and the like) constituting the bracket, respective portions (a pedestal portion, a flange pressing portion, an elastic coming-off prevention claw portion, a slide restriction portion, and the like) constituting the clip mounting portion, and respective portions (a base plate, a flange portion, an elastic engagement piece, a first abutment portion, a second abutment portion, and the like) constituting the metal clip, shapes and structures thereof are not limited to the above embodiment.

[0059] The base portion 21 of the bracket 20 has a shape that is long in the sliding direction S of the metal clip 50, but may have, for example, a substantially square plate shape or an elliptical plate shape. The pair of flange pressing portions 35 and 35 each have the substantially L-shaped frame shape, but the pair of flange pressing portions may each have, for example, a shape that extends obliquely so as to be a substantially inverted V shape when viewed from a front side (when viewed from the side in the sliding direction). Furthermore, in the elastic coming-off prevention claw portion 40, the protrusion 43 protrudes upward from the tip end portion of the extending piece 41, but a protrusion may protrude in a direction of approaching the inner surface of the base portion (downward).

[0060] In the metal clip 50, the base plate 51 has the long plate shape, but the base plate may have, for example, a square shape or an elliptical shape. Furthermore, the thread groove 56a is formed in the inner periphery of the cylindrical portion 56 and the inner periphery of the through hole, but a shaft portion of the pin member may be a tapping screw without forming a thread groove in the inner periphery of the cylindrical portion 56 and the inner periphery of the through hole. The pair of elastic engagement pieces may extend obliquely so as to have a substantially inverted V shape, and may engage with the inner periphery of the clip attachment hole. Furthermore, the flange portion 53 extends via one step 63, but the flange portion may extend via two or more steps. The first abutment portion 61 and the second abutment portion 62 are provided at the both side portions of the base plate 51 in the width direction Y2 and at the positions aligned with each other in the longitudinal direction X2, but the first abutment portion and the second abutment portion may be provided at misaligned positions at both side portions of the base plate in a width direction.

[0061] <Operations and Effects> Next, operations and effects of the sun visor attachment device 10 configured as described above will be described.

[0062] When the metal clip 50 is to be mounted to the clip mounting portion 30 of the bracket 20, as shown in Fig. 5, the side portion of the base plate 51 of the metal clip 50 on the side in the sliding direction S is inserted, in the inclined state, into tip end portions of the pair of flange pressing portions 35 and 35 of the pedestal portion 31 in an extending direction, so that the pair of flange portions 53 and 53 enter the inner sides of the pair of flange pressing portions 35 and 35. The pair of flange portions 53 and 53 of the metal clip 50 are guided while being in sliding contact with the pressing walls 37 and 37 of the pair of flange pressing portions 35 and 35, the back surface of the base plate 51 of the metal clip 50 gradually approaches the inner surface of the base portion 21 of the bracket 20 so as to be parallel to the inner surface, and the base plate 51 presses the protrusions 43 and 43 so that the pair of elastic coming-off prevention claw portions 40 and 40 are elastically deformed in the direction of approaching the inner surface of the base portion 21.

[0063] As described above, the metal clip 50 may also be slid in the sliding direction S in the state where the base plate 51 of the metal clip 50 is not greatly inclined with respect to the pedestal portion 31 and the back surface of the base plate 51 of the metal clip 50 is laid down so as to approach the inner surface of the base portion 21. In this case, each side edge portion 62a or the like of the base plate 51 of the metal clip 50 on the side in the sliding direction S presses the tapered surface 43a of the respective protrusion 43 to elastically deform the respective elastic coming-off prevention claw portion 40 in the direction of approaching the inner surface of the base portion 21, so that the pair of flange portions 53 and 53 can enter the inner sides of the pair of flange pressing portions 35 and 35.

[0064] When the metal clip 50 is maximally pushed in the sliding direction §, the side edge portion 62a of the base plate 51 on the side in the sliding direction S abuts against the slide restriction portion 45 (here, the side edge portion 62a of the second abutment portion 62, and the side edge portions of the step 63 and the flange portion 53 on the side in the sliding direction S abut against the slide restriction portion 45), so that further sliding is restricted. At the same time, the pair of elastic coming-off prevention claw portions 40 and 40 are elastically restored, so that the abutment surfaces 43b and 43b of the protrusions 43 and 43 are disposed to face the side edge portions 61a and 61a of the base plate 51 (the side edge portions 61a of the first abutment portions 61) on the side opposite to the sliding direction S (see Figs. 7 and 9). The pair of flange portions 53 and 53 of the metal clip 50 are disposed to face the inner surfaces 37b and 37b of the pressing walls 37 and 37 of the pair of flange pressing portions 35 and 35 (see Fig. 8). As a result, as shown in Fig. 6, the metal clip 50 is mounted to the clip mounting portion 30, so that the metal clip 50 can be temporarily held in the bracket 20.

[0065] In this state, even if the metal clip 50 is attempted to be separated from the inner surface of the base portion 21 of the bracket 20, the metal clip 50 is prevented from coming off from the pedestal portion 31 in the insertion direction F of the pin member 70 and held since the pair of flange portions 53 and 53 engage with the inner surfaces 37b and 37b of the pressing walls 37 and 37. Even if the metal clip 50 is attempted to be slid from the pedestal portion 31 toward the side opposite to the sliding direction S, the metal clip 50 is prevented from coming off from the pedestal portion 31 toward the opposite to side in the sliding direction S since the side edge portions 61a and 61a of the first abutment portions 61 and 61 abut against and are caught by the abutment surfaces 43b and 43b of the protrusions 43 and 43 of the pair of elastic coming-off prevention claw portions 40 and 40.

[0066] Therefore, the metal clip 50 is prevented from coming off from the pedestal portion 31 in the insertion direction F of the pin member 70 by the pair of flange pressing portions 35 and 35, and the metal clip 50 is prevented from coming off toward the side opposite to the sliding direction S by the pair of elastic coming-off prevention claw portions 40 and 40, so that the metal clip 50 can be firmly mounted to the clip mounting portion 30 and the metal clip 50 can be temporarily held in the bracket 20.

[0067] In a state where the metal clip 50 is temporarily held in the bracket 20 as described above, a posture is taken in which one side portion of the bracket 20 in the longitudinal direction X1 is moved away from the cushion member 2 and the attachment target member 1 and the other side portion of the bracket 20 in the longitudinal direction X1 approaches the cushion member 2 and the attachment target member 1, the hook 25 provided in the bracket 20 is obliquely inserted from a face side of the hook attachment hole 5 and caught in the hook attachment hole 5, and the pair of elastic engagement pieces 55 and 55 of the metal clip 50 are pushed in from a face side of the clip attachment hole 4 by causing the one side portion of the bracket 20 in the longitudinal direction X1 to approach the cushion member 2. The hook 25 engages with the back side of the hook attachment hole 5, and the base end portions 58 and 58 are pressed against the inner periphery of the clip attachment hole 4, so that the pair of elastic engagement pieces 55 and 55 are inserted into the clip attachment hole 4 while being elastically deformed. Furthermore, when the metal clip 50 is pushed in, the base end portions 58 and 58 of the pair of elastic engagement pieces 55 and 55 are inserted out of the back side of the clip attachment hole 4 and temporarily engage with the inner periphery of the clip attachment hole 4, and the outer peripheral edge portion 21a of the bracket 20 abuts against the face side peripheral edge of the bracket receiving hole 2a formed in the cushion member 2, so that the bracket 20 is temporarily held onto the clip attachment hole 4 via the metal clip 50. As shown in Figs. 11 and 12, the ceiling surface 45a of the slide restriction portion 45 abuts against the face surface of the attachment target member 1, the outer surfaces 37a and 37a of the pressing walls 37 and 37 of the pair of flange pressing portions 35 and 35 abut against the face surface of the attachment target member 1, and furthermore, a surface side of a predetermined portion of the base plate 51 of the metal clip 50 abuts against a face side peripheral edge of the clip attachment hole 4.

[0068] The pin member 70 is fastened and fixed to the cylindrical portion 56 of the metal clip 50. That is, the shaft portion 71 of the pin member 70 is inserted through the bracket side insertion hole 32 and the clip side insertion hole 57 of the metal clip 50 from a counterbored portion 21b side of the bracket 20, the thread groove 71a of the shaft portion 71 is screwed into the thread groove 56a of the metal clip 50, and the pin member 70 is rotated until the head portion 73 of the pin member 70 abuts against a bottom surface of the counterbored portion 21b. As shown in Figs. 11 and 12, the shaft portion 71 of the pin member 70 is inserted between the tip end portions 60 and 60 of the pair of elastic engagement pieces 55 and 55, so that the pair of elastic engagement pieces 55 and 55 are pushed away from each other, the base end portions 58 and 58 are expanded, and the base end portions 58 and 58 engage with the inner periphery of the clip attachment hole 4 with a higher engagement force than before insertion of the pin member 70. As a result, the metal clip 50 is finally fixed to the bracket 20, so that the bracket 20 can be attached to the clip attachment hole 4 via the metal clip 50. That is, the bracket 20 can be attached to the attachment target member 1, and thus the sun visor can be attached to the attachment target member 1.

[0069] It may be desired to remove the metal clip 50 from the bracket 20 due to maintenance, component replacement, or the like. In this case, the shaft portion 71 is removed from the cylindrical portion 56 by first rotating the pin member 70 in a direction opposite to a rotation direction during fastening and fixing described above. Since the pair of elastic engagement pieces 55 and 55 are elastically deformable, the pair of elastic engagement pieces 55 and 55 are pulled out from the clip attachment hole 4, and the hook 25 is pulled out from the hook attachment hole 5. Thereafter, by pressing the protrusions 43 and 43 of the pair of elastic coming-off prevention claw portions 40 and 40 in the direction of approaching an inner surface side of the base portion 21, the pair of elastic coming-off prevention claw portions 40 and 40 are elastically deformed so that the abutment surfaces 43b and 43b of the protrusions 43 and 43 are positioned so as not to face and abut against the side edge portions 61a and 61a of the first abutment portions 61 and 61, and the metal clip 50 is slid toward the side opposite to the sliding direction S with respect to the pedestal portion 31 while an elastically deformed state is maintained. As a result, the metal clip 50 can be removed from the clip mounting portion 30.

[0070] In the sun visor attachment device 10, when the metal clip 50 is to be mounted to the clip mounting portion 30, only by a simple work of sliding the base plate 51 of the metal clip 50 with respect to the pedestal portion 31 in the direction orthogonal to the insertion direction of the pin member 70, the pair of flange portions 53 and 53 can be pressed by the pair of flange pressing portions 35 and 35 and each side edge portion 61a of the metal clip 50 on the side opposite to the sliding direction S can be prevented from coming off by the respective elastic coming-off prevention claw portion 40, so that the metal clip 50 can be easily mounted to the clip mounting portion 30. When the metal clip 50 is to be removed from the clip mounting portion 30, the metal clip 50 can be easily removed from the clip mounting portion 30 by a simple work of sliding the base plate 51 of the metal clip 50 toward the side opposite to the sliding direction S during mounting of the clip in the state where each elastic coming-off prevention claw portion 40 is elastically deformed so as not to abut against the respective side edge portion 61a of the metal clip 50 on the side opposite to the sliding direction S. Thus, in the sun visor attachment device 10, the metal clip 50 can be easily attached to and detached from the clip mounting portion 30 of the bracket 20.

[0071] The pair of elastic engagement pieces 55 and 55 of the metal clip 50 mounted to the clip mounting portion 30 are inserted into the clip attachment hole 4 of the attachment target member 1 and engage with the inner periphery of the clip attachment hole 4, and the pin member 70 is inserted between the pair of elastic engagement pieces 55 and 55 through the bracket side insertion hole 32 and the clip side insertion hole 57, so that the elastic deformation of the pair of elastic engagement pieces 55 and 55 toward the inside of the clip attachment hole 4 is restricted. Therefore, the bracket 20 can be firmly attached to the clip attachment hole 4, and thus the sun visor can be firmly attached to the attachment target member fe

[0072] Furthermore, as shown in Fig. 12, a large margin of engagement of each of the pair of flange portions 53 and 53 of the metal clip 50 with a respective one of the pair of flange pressing portions 35 and 35 of the clip mounting portion 30 (large area of engagement of the inner surface 37b of the pressing wall 37 with the flange portion 53) can be ensured, so that the metal clip 50 is less likely to come off from the pedestal portion 31 in the insertion direction of the pin member 70. Therefore, the bracket 20 can be firmly attached to the clip attachment hole 4 and a high pullout load can be obtained.

[0073] In the embodiment, as shown in Fig. 12, the pair of flange pressing portions 35 and 35 of the clip mounting portion 30 and the base plate 51 can abut against the face surface side of the attachment target member 1, and the pair of flange portions 53 and 53 of the metal clip 50 are configured to extend at the positions closer to the base portion 21 than the pedestal portion due to the step 63 with respect to the base plate 51, so as to enter the inner sides of the pair of flange pressing portions 35 and 35.

[0074] With the above configuration, the base portion 21 of the bracket 20 can be brought close to the face surface side of the attachment target member 1, and thus the bracket 20 can be stably attached. In addition to the pair of flange pressing portions 35 and 35, the base plate 51 of the metal clip 50 can also abut against the face surface of the attachment target member 1, so that the pair of flange pressing portions 35 and 35 and the base plate 51 of the metal clip 50 can abut against the face surface of the attachment target member 1, and the bracket 20 and the metal clip 50 can be attached to the attachment target member 1 in a stable posture.

[0075] In the embodiment, the base plate 51 of the metal clip 50 further includes the first abutment portions 61 that can abut against the elastic coming-off prevention claw portions 40 by protruding more toward the side opposite to the sliding direction S of the base plate 51 with respect to the pedestal portion 31 than the base end portions 58 and 58 of the pair of elastic engagement pieces 55 and 55 in the erection directions and the second abutment portions 62 that can abut against the slide restriction portion 45 by protruding more toward the side in the sliding direction S of the base plate 51 with respect to the pedestal portion 31 than the base end portions 58 and 58 of the pair of elastic engagement pieces 55 and 55 in the erection directions.

[0076] With the above configuration, when the metal clip 50 is mounted to the clip mounting portion 30, the pair of elastic engagement pieces 55 and 355 erected from the base plate 51 are less likely to interfere with the elastic coming-off prevention claw portions 40 and the slide restriction portion 45 and thus can be easily elastically deformed. As a result, the pair of elastic engagement pieces 55 and 55 can be easily inserted into the clip attachment hole 4 during attaching of the bracket 20 to the attachment target member 1, and the pair of elastic engagement pieces 55 and 55 can be easily pulled out from the clip attachment hole 4 during removing of the bracket 20 from the attachment target member 1.

[0077] Furthermore, in the embodiment, the pair of elastic engagement pieces 55 and 55 are erected from the base plate 51 so as to face each other in the sliding direction S of the base plate 51 with respect to the pedestal portion 31, the bracket 20 is provided with the hook 25 at the position separated from the clip mounting portion 30 in the sliding direction S of the base plate 51 with respect to the pedestal portion 31, and the hook 25 engages with the hook attachment hole 5 formed in the attachment target member 1.

[0078] With the above configuration, during mounting of the metal clip 50 to the clip mounting portion 30, the metal clip 50 is easily pushed in. That is, an operator does not push a side edge portion of the elastic engagement piece 55 having many edges and corners, and the operator pushes a portion (here, the base end portion 58 or the intermediate portion 59) of the elastic engagement piece 55 which is not the side edge portion and has an ensured wide area, so that the metal clip 50 is easily pushed in.

[0079] By providing the hook 25, a higher pullout load can be obtained (since the hook 25 is caught in the hook attachment hole 5 when a pullout load acts in a direction in which the bracket 20 is removed from the attachment target member 1). Furthermore, the pair of elastic engagement pieces 55 and 55 are erected from the base plate 51 so as to face each other in the sliding direction S of the base plate 51 with respect to the pedestal portion 31, and when the pair of elastic engagement pieces 55 and 55 of the metal clip 50 are pushed into the clip attachment hole 4 while the hook 25 is caught in the hook attachment hole 5 of the attachment target member 1, a pressing force acting on each of the pair of elastic engagement pieces 55 and 55 from the clip attachment hole 4 is in the same direction as a direction in which the pair of elastic engagement pieces 55 and 55 face each other. Therefore, the pair of elastic engagement pieces 55 and 55 can be easily elastically deformed (bent and deformed), and the pair of elastic engagement pieces 55 and 55 can be easily inserted into the clip attachment hole 4 and can easily engage with the clip attachment hole 4.

[0080] The present invention is not limited to the embodiment described above, various modifications can be made within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention REFERENCE SIGNS LIST
