Description

前記第３フランク部は、前記第１連結外形の前記第１フランクから遠ざかる方向を向いてよく、前記第５フランク部は、前記第２連結外形の前記第１フランクから遠ざかる方向を向いてよい。例えば、前記パネルが、前記第１延出領域を下向きにして前記床に配置したとき、前記第３フランク部は、その前記第１フランク部への接続部から開始して、下向きに傾斜してよい。同様に、前記第５フランク部は、その前記第４フランク部への接続部から開始して、上向きに傾斜してよい。 The third flank may face away from the first flank of the first connecting profile and the fifth flank may face away from the first flank of the second connecting profile. For example, when the panel is placed on the floor with the first extension area facing downwards, the third flank slopes downwards starting from its connection to the first flank. good. Similarly, the fifth flank may slope upwards starting from its connection to the fourth flank.

前記第２フランク部は、前記第１連結外形の前記第１フランクから遠ざかる方向に向けられてよく、前記５フランク部は、前記第２連結外形の前記第１フランクから遠ざかる方向に向けられてよい。 The second flank may be oriented away from the first flank of the first connecting profile and the five flank may be oriented away from the first flank of the second connecting profile. .

図４Ａに示すように、前記第１フランク部、前記第２フランク部、および前記第３フランク部の各々は、第１フランク３０から遠ざかる方向を向いている。さらに、各フランク部は、前記対応する法線ベクトルが平行であるため、同じ方向を向いている。同様に、第２フランク４１の各前記フランク部は、第１フランク３１とは反対側の同じ方向を向いている。 As shown in FIG. 4A, each of said first flank, said second flank and said third flank faces away from first flank 30 . Furthermore, each flank faces the same direction because the corresponding normal vectors are parallel. Similarly, each said flank portion of the second flank 41 faces in the same direction opposite the first flank 31 .

図４Ｆの前記実施形態では、前記第１フランク部は第１フランク３０の方に向けられている。前記第３フランク部は、第１フランク３０から遠ざかる方向に向けられ、前記第２フランク部はパネル１の法線Ｎと平行である。同様に、前記第４フランク部は第１フランク３１の方に向けられ、前記第５フランク部はパネル１'の法線Ｎ'と平行であり、前記第６フランク部は第１フランク３１から遠ざかる方向に向けられる。
In the embodiment of FIG. 4F the first flank is oriented towards the first flank 30 . Said third flank is oriented away from first flank 30 and said second flank is parallel to normal N of panel 1 . Similarly, said fourth flank is directed towards the first flank 31, said fifth flank is parallel to the normal N' of the panel 1' and said sixth flank is away from the first flank 31. directed .
