DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 8-54010 discloses a seat member clip used for attaching a seat member such as a dash silencer to an automobile.
See FIG. 11). The clip 50 is attached to the seat member 51 by being attached to the seat member 51 and then pushed into a stud bolt B implanted in the body panel P.

A flange 53 having a diameter larger than the insertion hole 52 of the seat member 51 can receive a stud bolt B erected on the body panel P.
A support portion 54 stands upright on the same axis, and can be engaged with the stud bolt B by a locking claw 55 formed at a boundary portion with the flange 53. A pair of support arms 56 stand upright on the support portion 54, and a locking arm 57 projects from the tip of the support arm 56.

As a fixing operation of the sheet member 51, first, as shown in FIG. 10, the clip 50 is attached to the sheet member 51. That is, the clip 50 is inserted into the insertion hole 52 of the sheet member 51 from the front end side. In this case, the insertion is performed while the support arms 56 bend and deform in a direction approaching each other. When the two locking arms 57 pass through the surface of the sheet member 51, the support arm 56 is returned and deformed, so that the locking arm 57 is locked around the insertion hole 52.

When the clip 50 is attached to the seat member 51 as described above, the clip 50 is pushed in at the head 58 while being adapted to the stud bolt B, and is engaged with the stud bolt B at both locking claws 55. If they are combined, the sheet member 51 is fixed to the body (the state in FIG. 9).

[0006]

However, the following has been pointed out in the clip 50 as described above. That is, when the sheet member 51 is pulled upward, a force in the pushing direction acts on the distal ends of both the locking arms 57, so that the two support arms 56 are bent inward from the base portion thereof and deform. In this case, the distance between the front ends of the locking arms 57 is reduced, and the insertion hole 5
2, that is, a possibility of falling off from the sheet member 51.

The present invention has been devised in view of the conventional problems described above, and an object of the present invention is to provide a clip which can securely fix a sheet member.

[0008]

According to a first aspect of the present invention, there is provided a clip for fixing a sheet member having an insertion hole passing therethrough to a body via a shaft-shaped fixing member. A base formed to have a diameter larger than the insertion hole, a support portion erected from the base so as to be able to be loosely inserted into the insertion hole, and an upper end protruding outward from an upper end portion of the support portion to form the base. And a plurality of holding pieces for holding the sheet member between the holding member and the holding piece, which can be closed and deformed so as to be able to pass through the insertion hole when inserted into the insertion hole, and to be inserted after passing through the insertion hole. While the leg can be opened and deformed with a larger overhang length, the column has an inversion prevention projection which can be engaged with the base of each holding piece in order to prevent the holding piece from being inverted. Have been It is characterized in.

According to a second aspect of the present invention, in the first aspect, an elastic piece is provided on the support portion for assisting deformation of each of the holding pieces to open the leg, and this elastic piece is inserted into the insertion piece. It is characterized by being configured to be inserted into the hole with almost no gap and to be in contact with the shaft-shaped fixing member to restrict bending deformation.

[0010]

The clip according to the first aspect of the present invention is attached by pushing the clip from one side into the insertion hole of the sheet member. At this time, each holding piece is inserted into the insertion hole while bending and deforming in the closing leg direction,
After passing through the insertion hole, it returns and deforms with a protrusion larger than the insertion hole. The seat member with the clip attached thereto is fixed to the body via the shaft-shaped fixing member.

When the sheet member is pulled up, a force in the reversing direction acts on each of the pressing pieces. However, since each of the pressing pieces comes into contact with the reversing prevention portion to restrict the reversing operation, the reversing operation is restricted. Can be eliminated from the sheet member.

According to the second aspect of the present invention, each of the pressing pieces deformed to close the leg in the process of inserting the sheet member receives the elastic force from the elastic piece at the time when the pressing piece passes through the insertion hole, and the returning operation is performed. Since the support is assisted, the opening operation of each holding piece is ensured. Further, when the elastic piece is inserted into the insertion hole of the sheet member, there is substantially no gap with the insertion hole, and the inner surface of the elastic piece can contact the shaft-shaped member. Of the clip is thereby restrained, and thereby the play of the entire clip, that is, the displacement of the sheet member is also controlled, so that the seat member is securely fixed.

[0013]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. Clip C of this embodiment
Is used to attach a sound-insulating dash silencer (seat member S) having cushioning properties to a panel that separates an engine room and a vehicle compartment in an automobile. A plurality of stud bolts B (axial fixing members of the present invention) are erected on the panel P by welding or the like, and an insertion hole 2 is formed through the sheet member S so as to correspond to the stud bolts B. The sheet member S is fixed to the panel P by pushing the clip C into each stud bolt B in a state where the sheet member S is inserted toward the insertion hole 2.

FIG. 1 shows the entirety of a clip C formed of a synthetic resin material (for example, made of polyacetal). In the figure, reference numeral 1 denotes a base 1 whose outer diameter is formed sufficiently larger than the insertion hole 2 of the sheet member S. The upper surface of the base 1 has an inclined surface 4 which is inclined upward toward the center thereof, and a through hole 3 for receiving the stud bolt B penetrates the center thereof. A short cylindrical portion 5 having the same outer diameter as the insertion hole 2 is provided upright around the hole. A pair of locking claws 6 are provided at the upper opening edge of the short cylindrical portion 5 so as to face each other. The both locking claws 6 project slightly obliquely inward and can be flexibly deformed. It extends in a horizontal direction (not necessarily horizontal and may extend obliquely) and is formed sharply so that it can be locked to the stud bolt B with elastic force.

The opening edge of the short cylindrical portion 5 and the two locking claws 6
And a pair of supporting pieces 8 constituting the support portion 7 are formed upright at an interval substantially equal to the outer diameter of the stud bolt B. Both supporting pieces 8 are formed in a substantially prismatic shape, and upper ends thereof are connected by a connecting piece 9, and a circular head 10 is formed on the upper surface of the connecting piece 9. Further, both support pieces 8 are provided with elastic pieces 11, which are mainly used as holding pieces 1 described later.
2 assists the return operation and regulates rattling when the clip C is attached.

As shown in FIG. 4, the elastic pieces 11 extend substantially parallel to the line connecting the two supporting pieces 8 while holding the grooves 13 from the diagonally opposite ends of the two supporting pieces 8 respectively. With this, it is possible to deform inwardly. A protruding edge 14 is formed on the outer surface of both support pieces 8 and at a position substantially on the diameter of the base 1 over the entire height range of the support pieces 8 so as to be able to abut on the holding pieces 12 described below. .

However, as shown in FIG. 4, the tip position of the protruding edge 14 is set so as not to protrude from the outer peripheral edge of the short tube portion 5. That is, as described above, since the short cylindrical portion 5 is set to have an outer diameter substantially equal to that of the insertion hole 2, the clip C
When the is inserted into the insertion hole 2, the protruding edge 14 can contact the hole wall of the insertion hole 2. However, as shown in FIG. 6, in the process of inserting the clip C into the insertion hole 2, a setting is made such that a depression deformation including a thickness of the holding piece 12, which will be described later, can pass through the insertion hole 2. There is. Furthermore, clip C
Is inserted into the insertion hole 2, the inner surfaces of the two elastic pieces 11 are substantially in contact with the stud bolts B, whereby the bending of the elastic pieces 11 is restricted.

A pair of pressing pieces 12 project from the outer surface of the connecting piece 9 with a slight gap below the head 10. The two holding pieces 12 are arranged in the same direction as the two locking claws 6 are provided.
The two holding pieces 12 project obliquely downward in a natural state, and the distance between the tips in this state is set substantially equal to the outer diameter of the base 1 as shown in FIG. In other words, the sheet member S is formed to have a diameter sufficiently larger than the insertion hole 2 so that both the holding pieces 12 can connect the sheet member S to the base 1.
It can be sandwiched and held together. On the other hand, both the holding pieces 12 are allowed to be bent inward (bending deformation in the closing direction) so that they can pass through the insertion hole 2 (see FIG. 6), and the base of the holding piece 12 performs these bending operations. In order to facilitate this, it is formed slightly narrower.

There is a slight gap between the narrow portion and the head 10, so that the holding piece 1
2 is configured to be able to bend upward, but when it is bent over a predetermined angle (bending in the reverse direction),
Since the narrow portion abuts on the outer peripheral edge of the head 10 (this abutting portion corresponds to the inversion prevention protrusion 15), the two holding pieces 1
Excessive reversal operation for 2 is restricted.

The clip C of the present embodiment is constructed as described above, and the sheet member S is fixed as follows (see FIGS. 5 to 8).

First, the clip C is attached to the sheet member S. In this case, the clip C is positioned on the back side of the sheet member S, and the head 10 is fitted to the insertion hole 2. Then, when they are pushed in as they are, both holding pieces 12 are folded downward at a narrow portion at the base thereof, and furthermore, the elastic pieces 11 are narrowed through the protruding edges 14 of both elastic pieces 11. . Thus, clip C
The whole becomes a size that can pass through the insertion hole 2 and is inserted into the insertion hole 2. The elastic piece 11 is released and returned when the leading ends of both holding pieces 12 pass through the insertion holes 2, and are supported by this operation, so that both holding pieces 1 are supported.
2 is expanded and deformed.
Around the periphery, the sheet member S is stretched so as to hold down the sheet member S. Thereby, the clip C is held in a state where the sheet member S is sandwiched between the holding piece 12 and the base 1.

After attaching the clip C to each of the insertion holes 2 in the manner described above, the sheet member S is attached to the panel P.
Put on the surface. Then, the through hole 3 of the base 1 is fitted into the shaft end of the stud bolt B and is pushed in firmly. When the stud bolt B is pushed down to a predetermined depth, both the locking claws 6 are locked to the stud bolt B, so that the clip C is fixed to the panel P, that is, the sheet member S is fixed to the panel P. As described above, since the stud bolts B are substantially in contact with the inner surfaces of the elastic pieces 11, even if the sheet member S is to be displaced in the horizontal direction and deformed, the elastic pieces 11 are bent. Therefore, the displacement of the sheet member S is effectively eliminated.

On the other hand, as shown in FIG. 8, when the sheet member S is lifted, both holding pieces 12 are deformed in the reverse direction. However, since the base portion of the holding piece 12 is in contact with the inversion prevention protrusion 15 so that these inversion operations are not allowed above the horizontal state, the holding of the holding piece 12 against the sheet member S is held as it is. You.

The present invention can be variously modified.
The following modifications are also included in the technical scope of the present invention. In the present embodiment, a pair of holding pieces 12 are provided, but the number is not limited. The number may be three or more. Further, instead of the stud bolt B, a T-shaped shaft having no thread may be used. Further, the sheet member to be fixed may not necessarily have a cushioning property.
