[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat member fitting used for mounting a seat member such as a dash silencer in an automobile.

[0002]

2. Description of the Related Art As an attachment of a seat member used for attaching a seat member such as a dash silencer in an automobile, there is one disclosed in Japanese Utility Model Publication No. 1-13844. As shown in FIG. 8, this attachment includes a tubular main body 1A provided with a locking brim 1B and a locking piece 1C which deforms like a pantograph, and the locking piece 1C is raised as shown in the drawing. In the state, after penetrating into the mounting hole H of the sheet member S, the locking piece 1C is deformed so as to be crushed and held in this state. Then, the crushed and deformed locking piece 1C and the locking brim 1B are locked so as to be sandwiched between the front and back surfaces of the mounting hole H, so that the mounting tool 1 is mounted on the sheet member S. Then, when the tubular main body 1A is externally fitted to the stud bolts B erected on the vehicle body panel P and the locking claws 1D are locked to the male screw portion in a pull-out restriction state, the seat member S together with the fixture 1 is formed. It is attached to the panel P.

[0003]

However, the above-mentioned fixture 1
In the above, the width of the locking piece 1C is smaller than the diameter of the mounting hole H because the locking piece 1C needs to pass through the mounting hole H. For this reason, in the mounted state, the locking piece 1C cannot completely cover the opening of the mounting hole H, a part of the opening is exposed to impair the aesthetics, and the sound insulation is deteriorated. On the other hand, the fixture 2 shown in FIG. 9 has also been developed. This fixture 2 is a cylindrical body 3 having a locking collar 3A.
And a cap 4 having a locking collar 4A. When the tubular main body 3 is fitted into the mounting hole H from the back surface side of the sheet member S and the cap 4 is fitted into the tubular main body 3 from the front surface side, both sides are engaged. The stoppers 3A and 4A lock the sheet member S so as to sandwich the sheet member S, so that the fixture 2 is attached to the sheet member S. The attachment 2 has improved appearance and sound insulation by completely covering the opening of the attachment hole H with the circular locking collars 3A and 4A. In this case, since it is necessary to fit the cap 4 and the tubular body 3 from both the front surface and the back surface of the sheet member S, there is a problem that workability is poor. The present invention was devised in view of the above circumstances, and it is an object of the present invention to improve the aesthetics and sound insulation without lowering the workability of mounting on a sheet member.

[0004]

According to a first aspect of the present invention, a locking collar and a retaining collar are provided at both ends of a tubular main body, and the tubular main body is inserted into a mounting hole of a sheet member to lock the collar. And the retaining collar to the edge of the mounting hole from both the front and back sides, and by fitting the tubular body onto the shaft-shaped member standing on the mounting surface, the seat member can be mounted on the mounting surface. In the mounting member for the seat member, the retaining collar is formed of an elastic material into an umbrella shape inclined in a tapered shape over the entire circumference, and elastically bends in the closing direction when the mounting hole is inserted into the mounting hole. After passing through, the structure is characterized in that it is configured to cover around the mounting hole in a state in which the reverse bending to the side opposite to the cylindrical body is restricted.

According to a second aspect of the invention, in the first aspect of the invention, the retaining collar and the tubular body are formed as separate parts that can be assembled with each other, and the tubular body is formed of a material having high rigidity. However, it has a feature. A third aspect of the invention is characterized in that, in the first or second aspect of the invention, a rib is formed on the outer surface of the retaining collar in a radial direction so as to come into sliding contact with the mounting hole when the retaining hole penetrates the mounting hole. Have. According to a fourth aspect of the present invention, in any one of the first to third aspects of the invention, the base portion of the retaining collar is bent in the closing direction by thinning the outer surface thereof along the circumferential direction. It is characterized by the fact that an easily bendable portion is formed to facilitate it. According to a fifth aspect of the present invention, in the first or second aspect of the present invention, the outer surface of the retaining collar is thinned along the circumferential direction to facilitate bending of the retaining collar in the closing direction. A narrow groove-shaped flexible portion is formed, and a rib that slidably contacts the mounting hole when penetrating into the mounting hole is formed on the outer surface of the retaining collar in the radial direction with the groove edge of the flexible portion as the base end. When the retaining collar is about to be reversely bent, the proximal end of the rib comes into contact with the inner wall surface of the groove of the easily deflectable portion to restrict the reverse deflection of the retaining collar. .

[0006]

The attachment according to the first aspect of the present invention is attached to the seat member by pushing the retaining collar toward the attachment hole and pushing it into the attachment hole. At this time, the retaining collar is elastically bent so as to be closed and inserted into the mounting hole, and after passing through the mounting hole, elastically returns so as to expand and is locked to the hole edge of the mounting hole and the opening of the mounting hole. The whole part is covered. Since the retaining collar has an umbrella shape and its reverse bending is restricted, it exhibits a retaining function. As described above, according to the invention of claim 1, when the sheet member is mounted, only the insertion operation from one side thereof into the mounting hole is required, and the mounting hole is completely closed. It is possible to improve aesthetics and sound insulation without lowering the workability of mounting on the sheet member.

According to the second aspect of the present invention, since the tubular body is made of a material having high rigidity, a high fitting holding force can be obtained when the tubular body is externally fitted to the shaft member. Since the retaining collar and the tubular body are separate components, it is possible to improve both the ease of penetration of the retaining collar into the mounting hole and the fitting holding force of the tubular body with respect to the shaft-shaped member. In the invention of claim 3,
When the retaining collar penetrates the mounting hole, the ribs are arranged along the penetrating direction of the mounting hole as the retaining collar closes, and the rib extends along the length direction of the mounting hole. It is in sliding contact with the hole edge and inner surface. Therefore, compared with the case where the outer surface of the retaining collar is in sliding contact with a large area, the sliding contact resistance can be small and the operability of penetrating into the mounting hole is improved. In the invention of claim 4, since the easy-deflecting portion is formed, the retaining collar is easily deflected in the closing direction, so that the workability of mounting the retaining member on the sheet member is improved. In the invention of claim 5, when the retaining collar is bent in the closing direction and penetrates through the mounting hole, the rib is slidably in contact with the hole edge or the inner peripheral surface of the mounting hole along the length direction thereof. The sliding contact resistance is smaller than that in the case where the outer surface of the sliding contact is in a wide area, and the operability of penetrating into the mounting hole is improved. Further, since the easy-deflection portion is formed, bending of the retaining collar in the closing direction is facilitated, and in this respect also, the operability of penetrating into the mounting hole is improved. Further, even if the retaining collar is about to be bent in the reversing direction, the base end portion of the rib comes into contact with the inner wall surface of the groove of the easily deflectable portion, so that the reversing deflection of the retaining collar is restricted. Thus, according to the present invention,
The operability of penetrating into the mounting hole can be improved without deteriorating the retaining function of the retaining collar.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The mounting tool 10 of the present embodiment is a panel that partitions an engine room and a vehicle compartment in an automobile (a mounting surface that is a constituent feature of the present invention).
It is used to attach a sound insulation dash silencer (sheet member which is a constituent of the present invention) S to P. A plurality of stud bolts (a shaft-like member that is a constituent of the present invention) B are erected on the panel P, and mounting holes H corresponding to the stud bolts B are formed through the dash silencer S to form the stud bolts. The dash silencer S is attached to the panel P by mounting the mounting tool 10 of the present embodiment on B and fitting the mounting holes H into these mounting tools 10. The fixture 10 of the present embodiment is composed of a tubular body 11 and a cap 20 that are molded as separate parts. The tubular body 11 is made of a synthetic resin material and has high rigidity. The cap 20 is made of a synthetic resin material like the tubular body 11, but has an elasticity that allows it to be relatively easily bent. The tubular main body 11 and the cap 20 are attached to the dash silencer S in a state where they are integrally assembled.

First, the tubular body 11 will be described. Both the front end surface and the base end surface of the cylindrical main body 11 are open, and a concentric circular locking collar 12 is formed on the outer circumference of the base end portion. The locking brim 12 has an umbrella shape that widens at the bottom with the tip facing upward, and when mounted on the dash silencer S, when the dash silencer S is mounted, the dash silencer S is attached to the edge of the mounting hole H. It is designed to be locked from the back side. A pair of locking claws 13 that project obliquely inward toward the distal end side are formed on the inner circumference of the base end portion of the cylindrical main body 11 so as to correspond to each other with the shaft center interposed therebetween. When the tubular main body 11 is externally fitted to the stud bolt B from the base end side thereof, the locking claw 13 is adapted to slightly elastically bend outward while overcoming the ridge of the male thread portion of the stud bolt B. When the external fitting is completed, both locking claws 13 are positioned so as to sandwich the stud bolt B, and are locked in the valley of the male screw portion, so that the tubular body 11 is prevented from coming off from the stud bolt B. Has become. A pair of window holes 14 extending from the hollow to the outer peripheral surface are formed on the tip side of the locking claw 13 of the tubular body 11. The locking claw 13 faces the window hole 14, and the elastic bending of the locking claw 13 is allowed by forming the window hole 14. A pair of corresponding coupling projections 15 is formed on the outer periphery of the tip end of the cylindrical body 11 with the shaft center interposed therebetween.
This coupling projection 15 is a coupling hole 24 of the cap 20 described later.
By being fitted with, the tubular main body 11 and the cap 20
And can be assembled together.

Next, the cap 20 will be described. The cap 20 is configured to include a circular support portion 21 that is attached to the distal end portion of the tubular main body 11, and a concentric circular retaining collar 22 that extends outward from the peripheral edge of the support portion 21.
A circular tubular portion 23 is formed on the support portion 21 so as to be externally fitted to the tip portion of the tubular main body 11, and the rear surface (lower surface in FIG. 1) of the tubular portion 23 is fitted with the coupling projection 15. A pair of coupling holes 24 are formed. In addition, a jig fitting portion 25 formed of a linear groove is formed on the surface of the support portion 21 on the opposite side of the tubular portion 23. When a flat-blade screwdriver (not shown) is fitted into the jig fitting portion 25 and is rotated, the cap 20 and the tubular main body 11 are rotated and the stud bolt B is rotated.
It can be removed from the.

The retaining collar 22 is provided over the entire circumference and has an umbrella shape slightly inclined with respect to a plane orthogonal to the axial direction. The inclination direction is such that the surface of the supporting portion 21 is upward. It is set to widen the bottom when facing. Since the retaining collar 22 is made of a material that easily elastically bends as described above, it can easily elastically bend in a direction in which the umbrella is closed. However, when it is attempted to be bent in the reverse direction such that it becomes a cup shape, which is opposite to the closing direction, the outer peripheral edge of the retaining collar 22 is forcedly stretched due to the umbrella shape, Bending in the reversal direction is restricted by the reaction force generated with it.

The base of the retaining collar 22 is formed with an easily bendable portion 26 in the form of a narrow groove by thinning the surface in a concentric circular shape along the boundary edge with the support portion 21. By forming the easily bendable portion 26, the retaining collar 22 and the support portion 2 are provided.
Since the thickness of the boundary edge with 1 is thin, the retaining collar 22
The easiness of bending in the closing direction is improved. Also,
The inner wall surface of the easily bendable portion 26 on the side of the support portion 21 bends in the reversing direction of the retaining collar 22 when an abutting portion 29 of the rib 28 (deflection regulating portion which is a constituent feature of the invention) comes into contact with the inner wall surface. Is a receiving portion (deflection regulating portion which is a constituent feature of the present invention) 27 that regulates the.

Further, a plurality of ribs 28 extending in the radial direction from the center thereof are formed on the front side surface of the retaining collar 22 at equal angular intervals in the circumferential direction. The rib 28 is formed so as to project from the surface of the retaining collar 22 and
When 2 is closed and deformed and is pushed into the mounting hole H, the rib 28 is brought into sliding contact with the hole edge and the inner peripheral surface of the mounting hole H. Further, the end portion of the rib 28 on the center side is an abutting portion 29 that faces the flexible portion 26 and faces the receiving portion 27 thereof. The contact portion 29 serves as a receiving portion 2 when the retaining collar 22 is about to be bent in the reverse direction (front side).
7, so that further reversal bending of the retaining collar 22 is restricted.

Next, the operation of the present embodiment will be described. The fixture 10 of the present embodiment is a dash silencer S.
Prior to mounting on the tubular body 11, the tubular body 11 and the cap 20 are assembled and integrated. Assembling is the cylindrical portion 2 of the cap 20.
This is performed by elastically bending 3 while covering the distal end portion of the cylindrical main body 11 to fit the coupling hole 24 and the coupling projection 15 together. When the coupling protrusion 15 and the coupling hole 24 are fitted together, the tubular body 11 and the cap 20 are integrated so that they cannot be removed in the axial direction and relatively displaced in the circumferential direction. The fixture 10 assembled as described above is fitted to each stud bolt B of the panel P. The fitting is performed by pressing the tubular body 11 from the base end side (the side on which the locking flange 12 is formed) to the stud bolt B so as to be fitted externally. Then, the locking claw 13 elastically flexes outward and rides over the male thread portion of the stud bolt B,
The fitting operation is completed when the locking collar 12 comes into contact with the panel P and cannot be pressed further (see FIG. 5). In this state, as shown in FIG. 4, the locking claw 13 is locked to the male thread portion of the stud bolt B, so that the attachment tool 10 is attached to the stud bolt B in a state where removal thereof is restricted.

Next, as described above, the stud bolt B
The rear surface of the dash silencer S is attached to the panel P while pressing the attachment hole H against the attachment 10 attached to the panel P.
In close contact. Then, in each mounting hole H, the cap 20
The tubular body 11 is pushed in with the side facing first. With this pushing operation, the retaining collar 22 has its rib 2
8 is brought into contact with the hole edge of the mounting hole H so that the cylindrical main body 1
1 enters into the mounting hole H while elastically closing and deforming so as to approach the outer peripheral surface of 1 (see FIG. 6). At this time, since the retaining collar 22 is made of an elastic material that is likely to bend and the easily bendable portion 26 is provided, the retaining collar 22 easily bends in the closing direction. Moreover, by providing the rib 28 on the outer surface of the retaining collar 22, the sliding contact resistance with the mounting hole H is reduced. Therefore, the resistance against the pushing operation into the mounting hole H is small and the operability is excellent.

Then, the hole edge on the back side of the mounting hole H is the locking brim 1.
When the dash silencer S is further pressed against the panel P even after being locked to 2, the back side of the dash silencer S is deformed so as to be elastically crushed by the locking brim 12 while the retaining brim 22 passes through the mounting hole H. Then, it projects to the front side of the dash silencer S. Then, the retaining collar 22 expands like an umbrella due to its elastic restoring force to close the opening of the mounting hole H. When you release your hand from the dash silencer S in this state,
The dash silencer S is elastically restored and the retaining collar 22
The locking collar 12 is locked so as to sandwich the hole edge of the mounting hole H from both sides of the front surface and the back surface, and as shown in FIG. 7, the dash silencer S moves in the insertion / removal direction with respect to the mounting tool 10. Be in a regulated state. Since the locking brim 12 is integrally molded with the highly rigid tubular body 11, it exhibits a reliable locking function. Further, although the retaining collar 22 is easily bent in the closing direction, the retaining collar 22 has an umbrella shape, and the easily deflectable portion 26 has the receiving portion 27 and the abutting portion 29.
Since the bending of the reverse direction opposite to the closing direction is restricted by the provision of the above, the retaining collar 22 also has a high locking function similarly to the locking collar 12. As described above, the dash silencer S is attached to the panel P in a state in which the attachment / removal is restricted by the attachment 10.

When removing the dash silencer S from the panel P, if a minus driver is fitted into the jig fitting portion 25 and the cap 20 is rotated, the cylindrical main body 11 rotates together with the cap 20. Along with this, the locking claw 13 moves along the spiral of the male screw portion, so that the fixture 10 is removed from the stud bolt B and the dash silencer S is removed from the panel P. When the once removed dash silencer S is attached to the panel P again, the dash silencer S may be pressed against the panel P while the attachment 10 is still attached to the attachment hole H. As a result, the fixture 10 is attached to the stud bolt B and the dash silencer S is attached to the panel P.

As described above, the fixture 10 of the present embodiment.
Is provided with a retaining collar 22 that elastically bends easily in the closing direction that allows the retaining collar 22 to be inserted into the mounting hole H.
The dash silencer S can be easily attached by simply pushing the button toward the mounting hole H from the back side. Moreover, in the mounted state, the retaining collar 22 elastically restores to an umbrella shape so as to block the opening of the mounting hole H entirely. Thus, according to the present embodiment,
The workability of mounting the dash silencer S is excellent, and the appearance of the mounting hole H and the sound insulation are improved.

Further, since the tubular main body 11 is made of a material having a high rigidity, when the locking pawl 13 of the tubular main body 11 is locked to the male screw portion of the stud bolt B, the locking pawl 13 is bent in the releasing direction. There is no fear of the attachment, and the attachment 10 is securely attached to the panel P. Moreover, since the cap 20 having the retaining collar 22 and the tubular body 11 are separate parts, both the high retaining function of the tubular body 11 with respect to the stud bolt B and the ease of penetration of the retaining collar 22 into the mounting hole H are provided. It is possible to achieve both at a high standard.

When the retaining collar 22 penetrates the mounting hole H, the ribs 28 are arranged along the direction of penetrating the mounting hole H as the retaining collar 22 closes. Reference numeral 28 is slidably in contact with the hole edge or the inner peripheral surface of the mounting hole H along the length direction. Therefore, the sliding contact resistance is smaller than that in the case where the outer surface of the retaining collar 22 is in sliding contact with a wide area, the penetration operation into the mounting hole H is facilitated, and the workability of mounting the dash silencer S is excellent. . In addition, since the easy-deflection portion 26 is formed, the retaining collar 22 is easily deflected in the closing direction, and the elastic restoring force of the retaining collar 22 is reduced, so that the sliding contact resistance is reduced. Also, it is easy to penetrate the mounting hole H.

Further, in this embodiment, as a means for forming the easily bendable portion 26 for improving the ease of bending of the retaining collar 22 in the closing direction, the wall thickness of the bendable portion is thinned by thinning. Although it is easy to bend in the reverse direction opposite to the closing direction, in the present embodiment, since the receiving portion 27 and the contact portion 29 are provided as a means for restricting the bending in the reverse direction, the retaining It is prevented that the collar 22 bends in a reverse direction and its retaining function is impaired.
