Description

The present invention relates to a louver provided with a lattice.

A grid may be provided at the window opening for the purpose of crime prevention. In many cases, the lattice is attached to the outdoor side of the window opening, and the lattice is attached to the outside even in a so-called louver sash. However, attaching the grid outside the room not only requires work different from the sash installation work, but also often damages the exterior of the building.

Patent Documents 1 and 2 describe a louver sash in which a lattice is attached to the indoor side. However, in these cases, a metal rod for forming a lattice is directly attached to an operation member that rotates each blade body constituting the louver, and retrofitting to an existing louver sash is difficult. In addition, none of the documents discloses so-called double louvers, and the double louvers themselves are known, but none of the references mentions the relationship between the lattice and the double louvers. Absent.

An object of this invention is to provide the louver provided with the grating | lattice which can be retrofitted with respect to the existing louver sash.

The technical means adopted by the present invention are provided in the width direction of the window frame and provided at both end portions of the plurality of blade plates with both end portions pivotally supported on the left and right expected surfaces of the window frame. Left and right actuating members connected to the arm pieces and movable in the vertical direction, operating means for supporting at least one of the actuating members so as to move up and down, and a grid provided on the indoor side of the plurality of blades The lattice includes a ladder from left and right vertical members extending in the height direction of the window frame, and a plurality of horizontal members extending horizontally in the vertical direction between the vertical members. The lattice is a louver provided with a lattice that moves up and down in conjunction with rotation of the blades by fixing the left and right vertical members to the left and right actuating members, respectively. .

In one aspect, the plurality of blades are arranged at a predetermined interval in the vertical direction on the indoor side of the window frame and a plurality of outdoor blades arranged at a predetermined interval in the vertical direction on the outdoor side of the window frame. A plurality of indoor slats arranged in a row, and the plurality of outdoor slats and the indoor slats are configured to rotate in parallel with each other. When rotated to the fully open posture (horizontal posture in the embodiment described later), the height position of the horizontal member of the lattice is the indoor side of the outdoor blades in the fully open posture, and the indoor side of the outdoor blades It is configured to move to the same position as the height of the end.

In one aspect, the plurality of blades are arranged at predetermined intervals in the vertical direction and are configured to rotate in parallel with each other, and the blades are in a fully open position. When rotated, the height position of the horizontal member of the lattice is configured to move to the same position as the height of the indoor side end of the blade plate on the indoor side of the blade plate in the fully open posture. .

In the present invention, since the lattice is formed of a ladder-like unit, the existing louver without the lattice can be made into a louver with a lattice by attaching the vertical member to the operating member of the existing louver. Further, if the fastening member for attaching the vertical member to the operating member is constituted by a detachable means such as a screw, the lattice can be detachably attached to the existing louver.

When the plurality of blades are rotated to the horizontal posture with the window open, the height position of the transverse member of the lattice is the height of the outdoor blades on the indoor side of the outdoor blade plate in the horizontal posture. In the structure configured to move to the same position, although the lattice is provided, the lateral member of the lattice does not hinder the cleaning of the louver blade. In particular, this effect is useful in a double louver in which the distance between the outdoor blade and the indoor blade is small. In addition, when the window is fully open, the lattice horizontal member is located on the interior side of the blade, so that when viewed from the outdoor side, the lattice horizontal member is hidden, and the aesthetics when opened are good. Further, when the window is fully opened, the open area formed between the blades in the fully open position is not narrowed by the cross member of the lattice.
