DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing a wall member mounting structure according to the present invention. A plurality of aggregates 2 to which the wall material 1 is attached are erected in parallel with each other in the same manner as the aggregate 21 shown in the conventional example. A rail member 3 having a C-shaped cross section is bolted to the aggregate 2 so as to be horizontal, for example. Then, the wall material 1 to which the wallpaper has been pasted or surface-treated in advance is attached to the rail member 3 via a clip composed of a grommet 4 and a pin 5 which are each formed of a synthetic resin material.

As shown in FIG. 2, the grommet 4 includes a head 6 having a flat U-shaped cross section and a substantially rectangular tubular portion 7 integrally formed so as to extend from the head 6. Have The inside of the tubular portion 7 and the opening 8 formed in the head portion 6 are coaxially communicated with each other, and the upper and lower portions of the peripheral wall of the tubular portion 7 in the drawing are provided with a part of the peripheral wall. A pair of flexible leg pieces 9 are formed on the upper and lower sides so as to be cut. On the outer surface of the flexible leg piece 9, an engaging claw 9a having a triangular cross-section projecting outward from the outer surface of the tubular portion 7 is projected, and the inner surface of the flexible leg piece 9 is tubular. An inward projection 9b is provided so as to project inward from the inner surface of the portion 7.

The pin 5 has a substantially rectangular bottomed cylindrical shaft portion 11 formed so as to be inserted into the cylindrical portion 7 without much play, and an open end portion of the shaft portion 11. And a head portion 12 having an outward flange portion extending in the vertical direction. The pin 5 is fixed to the wall material 1 by screwing a tapping screw 13 inserted into a mounting hole provided in an outward flange portion of the head portion 12 into the back surface of the wall material 1.

The procedure for mounting the wall member mounting structure thus configured will be described below. First, as described above, the pin 5 is fixed to the back surface of the wall material 1 and the grommet 4 is attached.
The cylindrical portion 7 is inserted into the C-shaped cross-section groove 3a of the rail member 3 as shown by an arrow A in FIG. The length between the outer surfaces in the vertical direction of the tubular portion 7 is such that it can be inserted through the opening of the groove 3a and is substantially equal to the opening width thereof. Therefore, when the tubular portion 7 is inserted into the groove 3a, the engaging claw 9a collides with the inward flange portion 3b of the rail member 3, but the flexible leg piece 9 is elastically deformed inward and the rail The engaging claw 9a can dodge the inward flange 3b of the member 3.

Further, when the grommet 4 is pushed until the left and right wall portions of the head portion 6 come into contact with the surface of the inward flange portion 3b of the rail member 3, the engaging claws 9a completely enter the groove 3, The flexible leg piece 9 elastically returns, and as shown in FIG. 3, the engaging claw 9a engages with the back side of the edge of the inward flange 3b, which is the back side of the opening edge of the groove 3a of the rail member 3, The grommet 4 is retained and temporarily fixed.

Next, the shaft portion 11 of the pin 5 fixed to the wall member 1 is attached to the grommet 4 as shown by an arrow B in FIG.
It is inserted into the tubular portion 7 through the opening 8. The outer shape of the shaft portion 11 is formed so that it can be fitted into the tubular portion 7. Therefore, by pushing in the shaft portion 11,
The inward projections 9b of the flexible leg pieces 9 are provided on the upper and lower portions of the outer peripheral surface of the
And the flexible leg pieces 9 are pushed outward and the engagement state of the engagement claw 9a is reliably maintained.

In this way, the wall member 1 is attached to the rail member 3 on the aggregate 2 side. Since the grommet 9 is attached by engaging the engaging claw 9a with the inward flange 3b of the rail member 3 as described above, the grommet 9 can be moved in the axial direction of the rail member 3. Therefore, even if there is a gap between the adjacent wall members 1, it can be easily adjusted even after being attached to the aggregate 2 side, and it is not necessary to fill the joint with putty as in the conventional example. Further, the shaft portion 11 can be displaced with respect to the axial direction of the tubular portion 9, and adjustment in the front-back direction with respect to the aggregate 2 is also possible.

Further, since the shaft portion 11 is simply inserted and fitted in the tubular portion 9, the wall material 1 can be peeled off to easily separate the grommet 4 and the pin 5 from each other. It is possible to repeatedly use a clip composed of both.

[0016]

As described above, according to the present invention, the tubular portion of the grommet is inserted into the groove on the aggregate side so that the engaging claw of the flexible leg piece is engaged with the edge of the groove on the aggregate side. The grommet is attached to the grommet, the shaft of the pin fixed to the wall material is inserted into the cylindrical part of the grommet, and the wall material is attached to the aggregate, and the rivets and screw heads are exposed on the surface of the wall material. There is no need to bury it with putty, and wall material installation work can be simplified, and the shaft of the pin can be pulled out from the tubular part of the grommet, and the pin and grommet clip can be used repeatedly. Is possible. Further, by fixing a rail member having a C-shaped cross-section to the aggregate and engaging a grommet with the groove having the C-shaped cross-section, the wall material can be displaced in the axial direction of the rail member. Since the position of the joint between the adjacent walls can be adjusted even after the attachment, the work of filling the joint with the putty is not required and the workability of the attachment can be further improved.
