Slideable panel unit interlock

A slideable panel unit interlock, the unit having a first panel and a second panel, one of the panels being a slideable panel, comprising:

• (a) a first weatherstrip cooperatively connected to the first panel and extending substantially the length of the first panel, said first weatherstrip having a first member cooperatively connected to a second member, said second member extending away from the first panel, whereby said first member is in a spaced relationship to the first panel;
• (b) a second weatherstrip cooperatively connected to the second panel and extending substantially the length of the second panel, said second weatherstrip having a first member cooperatively connected to a second member, said second member extending away from the second panel, whereby said first member is in a spaced relationship to the second panel and when the panels are in a closed position said first member of said first weatherstrip is between said first member of said second weatherstrip and the second panel;
• and
• (c) one of said weatherstrips having its first member having a width at its center region smaller than its width at at least one of its ends, whereby when the panels move from an open position to a closed position, said smaller center width preventing clashing when one of the panels is bowed.

A slideable panel unit comprising:

• (a) a first panel;
• (b) a second panel, said second panel slideable with respect to said first panel between an open position and a closed position;
• (c) a first weatherstrip cooperatively connected to the first panel and extending substantially the length of the first panel, said first weatherstrip having a first member cooperatively connected to a second member, said second member extending away from the first panel, whereby said first member is in a spaced relationship to the first panel;
• (d) a second weatherstrip cooperatively connected to the second panel and extending substantially the length of the second panel, said second weatherstrip having a first member cooperatively connected to a second member, said second member extending away from the second panel, whereby said first member is in a spaced relationship to the second panel and when the panels are in a closed position said first member of said first weatherstrip is between said first member of said second weatherstrip and the second panel;
• and
• (e) one of said weatherstrips having its first member having a width at its center region smaller than its width at at least one of its ends, whereby when the panels move from an open position to a closed position, said smaller center width preventing clashing when one of the panels is bowed.
