Louvers for movable louver device

Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to a louver of a movable louver device used as a surface grid, a fence, or the like.

【0002】

[Conventional technology]

In a movable louver surface grid generally used as a movable louver device, for example, horizontally long louvers are arranged in a multi-stage shape in a surface grid peripheral frame composed of left and right vertical frames and upper and lower horizontal frames, and both ends of each louver are arranged. It is pivotally supported by both the left and right vertical frames. Each louver has a louver body formed in a hollow strip shape having a required plate thickness, width and length by an extruded aluminum mold material, and the louver body has a central portion in the width direction and a center in the plate thickness direction. A shaft hole for inserting a pin for shaft support is formed through the portion from both vertical frame sides in the length direction of the louver body.

【0003】

[Problems to be Solved by the Invention]

By the way, the applicant of the present application has placed a plurality of columns in, for example, a window opening, and has louver support arms projecting from each column at a constant pitch in the length direction, so that the louvers of each column are projected. We proposed a movable louver device that pivotally supports the louver on the support arm, but in this movable louver device, the louver support arm is placed at the required location on the back side (the surface facing the indoor side when the louver is closed) of each louver. An opening is formed in the notch groove into which the tip can be inserted, the tip of the arm is inserted into the shaft hole inside the louver body from this notch, and the pivot pin is inserted between this shaft hole and the pin hole at the tip of the arm. By inserting the louver, the louver is rotatably supported by the louver support arm.

【0004】

However, in such a louver, unlike the conventional louver main body, the shaft hole into which the pivot pin is inserted is formed through the central portion in the width direction and the central portion in the plate thickness direction of the louver body. If there is, if the plate thickness of the louver body is not formed to be considerably thick in advance, the notch groove formed by cutting from the back side of the louver body is the surface side of the louver body (the surface facing the outdoor side when the louver is closed). If this happens, an opening will be created on the surface side of the louver body, which not only spoils the appearance when the louver is closed, but also causes rainwater to infiltrate when it rains, which is extremely inconvenient. Situation occurs. Further, if the plate thickness of the louver body is made thicker, the weight becomes heavier and the cost becomes higher.

【0005】

An object of the present invention is to provide a louver for a movable louver device in which a notch groove for inserting a louver support arm does not penetrate the surface side of the louver body without particularly increasing the plate thickness.
