[0010]

As described above, a dedicated lower member is required to attach the upper member of the joiner, the upper member of the parting edge, the upper member of the outer corner, and the upper member of the inner corner. There is a problem to be solved that the number of components to be increased increases.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lower joiner member that requires fewer types of members to be supplied to the site.

[0012]

According to a first aspect of the present invention, a lower joiner member has a back plate portion and an upright portion rising from the back plate portion, and the upper joiner member is locked to the upright portion. In the lower joiner member, a weak portion extending in the longitudinal direction of the lower joiner member is provided on the back plate portion, and the back plate can be divided along the weak portion.

Such a lower joiner member can be used as it is as a lower joiner member of the flat portion, or can be used as a lower member for a parting edge by dividing the back plate along the weak portion.

A groove or a perforated slit is preferably used as the fragile portion.

According to a second aspect of the invention, there is provided a lower joiner member having a back plate portion and an upright portion rising from the back plate portion, wherein the upper joiner member is locked to the upright portion. A back plate portion is provided with a bendable portion extending in the longitudinal direction of the lower joiner member,
The back plate portion can be bent along the bendable portion.

Such a lower joiner member can be used as it is as a lower joiner member of the flat portion. In addition, by bending the back plate portion along the bendable portion, the back plate portion can be used as a lower member of an outside corner or an inside corner.

Preferably, the lower joiner member is made of synthetic resin as a whole, and the bendable portion is made of soft synthetic resin.

[0018]

FIG. 1 shows a lower member of a joiner according to an embodiment.

The lower joiner member 30 has a T-shaped cross section having a back plate portion 30b and an upright portion 30a. As in the prior art, the upright portion 30a has a pair of elastic pieces arranged facing each other so that the insertion piece 31a of the upper joiner member 31 can be inserted.

A groove 32 extends in the back plate portion 30b in the longitudinal direction of the lower joiner member 30, and the back plate portion 3 extends along the groove 32 as shown in FIG.
0b can be divided.

In the lower joiner member 30, as shown in FIG. 1B, it can be used as it is as a lower joiner member of a flat portion as shown in FIG. Groove 3
By dividing the back plate portion 30b along 2, the lower joiner member 30b can be used as a lower member for mounting the upper rim member 16.

In this embodiment, the groove 32 is provided. Instead, the back plate portion 30b such as a perforated slit (a slit provided at a predetermined interval) is easily divided. Various vulnerable portions in a linear shape can be employed.

It is sufficient that only one linear weak portion such as the groove 32 is provided, but a plurality of linear weak portions may be provided. In this case, the fragile portion may be provided on both sides of the erected portion 31a with different distances between the fragile portion and the erected portion.

FIG. 2 shows a lower member of a joiner according to another embodiment.

The lower joiner member 33 has a back plate portion 33b and an upright portion 33a rising from the back plate portion 33b. This lower joiner member 33
Is made of synthetic resin as a whole. Along the both sides of the base of the upright portion 33a, the back plate portion 33
The b has a flexible portion 34 as two bendable portions. The soft portion 34 is made of a synthetic resin that is softer than the surrounding synthetic resin. The lower joiner member 33 can be formed, for example, by simultaneously extruding soft PVC (vinyl chloride) and harder PVC.

The lower joiner member 33 is used as a lower joiner member of a flat portion as shown in FIG. 2 (a), and by bending a back plate portion 33b along the soft portion 34, as shown in FIG. ) Can be used as a lower part of the corner, as shown in FIG. 2 (c).
It can also be used as the lower corner member of the outer corner as shown in FIG.

Note that both the soft portion 34 shown in FIG. 2 and the fragile portion such as the groove shown in FIG. 1 may be provided on the lower joiner member.

[0028]

As described above, the lower joiner member of the present invention can be used not only as a lower joiner member of a flat portion but also as a lower member such as a parting edge, a protruding corner, and a corner near a window. Therefore, by employing the joiner lower member of the present invention, the types of lower members to be carried into the construction site can be reduced, and the labor of arranging and transporting members, inventory management, etc. can be greatly reduced. It becomes possible.
