Screen apparatus and method for producing the same
Included are: a screen member 33: a fitter member 35 attached to a side end 33 a of the screen member 33; a rail member 91 having a first chamber 91 a and a first slit 91 b joining the first chamber 91 a, the first chamber 91 a accommodating the side end 33 a of the screen member 33 and the fitter member 35 passing through the first slit 91 b to thereby allow the rail member 91 to hold the screen member 33 movably in a longitudinal direction of the first slit 91 b; and a retainer 93 for retaining the rail member 91. The rail member 91 is compressively deformed in the width direction of the first slit 91 b by the retainer 93, and the width of the first slit of the compressively deformed rail member 91 is narrower than the thickness T 1 of the fitter member 35.
1. A screen apparatus, comprising:
a screen member;
a fitter member attached to a side end of the screen member;
a rail member including a first chamber surrounded by a first wall portion, and a first slit formed through a surface of the first wall portion to communicate with the first chamber, the first chamber accommodating the fitter member and the side end of the screen member to thereby allow the rail member to hold the screen member movably in a longitudinal direction of the first slit;
a retainer member for retaining the rail member, the retainer member including a second chamber surrounded by a second wall portion to accommodate the rail member, and a second slit formed through the second wall portion along the longitudinal direction of the first slit to communicate with the second chamber and the first slit;
a weight bar attached to a lower end of the screen member in such a manner as to extend along the lower end;
an inner guider having two first side walls and a third chamber defined between the two first side walls to accommodate the retainer member; and
an outer guider having two second side walls and a cavity defined between the two second side walls to accommodate the inner guider, wherein
the retainer member has a rigidity higher than a rigidity of the rail member,
the second wall portion has an inner surface defining the second chamber, the inner surface including a first surface through which the second slit opens, a second surface located opposite to the first surface across the second chamber, and a first lateral surface and a second lateral surface respectively connecting the first surface and the second surface and facing each other across the second chamber,
the second chamber has a width set such that the rail member is compressively deformed in a width direction of the first slit by a contact with the first lateral surface and the second lateral surface of the second wall portion, and
the second slit has a width larger than a width of the first slit and narrower than a thickness of the fitter member in a state that the rail member is accommodated in the second chamber,
the rail member is in contact with each of the first lateral surface and the second lateral surface at a region closer to the first surface, and defines a gap with each of the first lateral surface and the second lateral surface at another region closer to the second surface, and
opposite ends of the weight bar are located in the cavity of the outer guider.
