Description

  The present invention relates to a louver for outdoor installation, in which louvers formed by extrusion molding of a metal material such as an aluminum alloy are arranged side by side, assembled to a frame material, assembled in a plane lattice, and installed on the outer surface side of a building. The present invention relates to a draining device to be installed on a vehicle.

  Metal blinds for outdoor installation that are assembled by assembling louvers formed by extruding metal materials in parallel with the frame material are widely used for blindfolding windows on the exterior of office buildings and blindfolds on the terraces of apartments. ing.

  In this metal blind for outdoor installation, each of the louvers to be juxtaposed in multiples is mounted on a mounting portion formed on the base end side of the louver, and a mounting bolt is usually connected by the mounting bolt. As a frame, it is assembled into a surface lattice shape by assembling and connecting to a frame material formed of steel material in an angled cross section, and a frame material as a connection frame is mounted on an outer frame side of the building frame, It is installed on the outer surface of the building frame by connecting it by means such as bolting.

  The louver is formed in a hollow square shape curved downward in a side cross section. Therefore, in rainy weather, when raindrops falling on the upper surface of the upper wall of the louver that curves downward toward the tip end flow down along the upper surface of the upper wall and reach the tip, the raindrops from the tip of the louver to the bottom It wraps around the lower surface of the wall, flows toward the mounting part on the base end side, gathers at the joint part between the mounting bolt fitted to the mounting part and the connecting frame, and flows down along the surface of the connecting frame from there. As a result, the connection portion between the mounting bolt and the connection frame and the connection frame play a role of a rain gutter, and there is a problem that the corrosion of the connection portion is accelerated.

  For this reason, it goes around from the upper surface of the top wall of the louver to the lower surface of the bottom wall, flows along the lower surface, flows to the joint portion between the mounting bolt at the base end of the louver and the connection frame, and then flows down along the outer surface of the connection frame. It is desirable to provide a draining means for blocking the flow of rainwater that is going to flow in front of the mounting bolts. For this reason, the tip end side of the top wall of the louver is extended beyond the junction with the bottom wall. It is made to protrude like an eave, and draining is performed by the extension wall of this top wall. However, the effect is not so large, and the extension wall that protrudes like an eave is easily damaged or deformed during handling. It has created another problem.

  The problem to be solved in the present invention is that, during rainfall, the rainwater flows around the lower surface of the bottom wall of the louver of the metal blind and flows into the joint portion between the mounting bolt of the louver and the connection frame. A drain device attached to the blind so as to shut off the water in front of the louver can be installed without impairing the strength of the louver so that the drain can be performed properly.

  As shown in FIG. 1, the drainage means in the metal blind for outdoor installation according to the present invention is a base end of an internal space formed by a top wall 10 and a bottom wall 11 of the louver 1 on the base end side thereof. The partition wall 12 that vertically partitions the sides, the base ends 10a and 11a of the top wall 10 and the bottom wall 11, and the base ends of the base ends 10a and 11a are bent in the vertical direction so as to be split vertically. In the louver 1 provided with a lateral channel-like mounting frame part a for fitting the head 20 of the mounting bolt 2 with the opposed bent walls 13 and 14, mounting is performed on the base end side of the bottom wall 11 of the louver 1. A bent wall b for bending the bottom wall 11 upward and rearward is formed at a portion of the frame portion a located on the front side of the partition wall 12, and an end of the bent wall b is attached to the mounting frame portion a. Connected to the front of the partition wall 12 above the lower edge of the partition wall 12 The bent wall b and the front surface of the partition wall 12 of the mounting frame portion a wrap around the lower surface of the bottom wall 11 of the louver 1 and transmit the lower surface to the connecting portion between the mounting bolt 2 and the connection frame 3. It is characterized in that the flow of rainwater flowing toward the front of the louver 1 is interrupted in front of the mounting bolt 2 so as to flow along the front surface of the partition wall 12 and to flow below the louver 1.

  In the drain device for a metal blind for outdoor use according to the present invention, the rainwater falling on the upper surface of the louver flows around the lower surface of the bottom wall of the louver, flows along the lower surface of the bottom wall, and flows toward the mounting bolt of the louver. In order to prevent the rainwater, use the mounting frame part formed on the base end side of the louver to block the flow of rainwater at the front of the partition wall of the mounting frame part, and to fall down Therefore, draining will be performed properly. In addition, since the drainage is performed in a form in which the drainage is fitted from the outer surface of the louver, the louver is not damaged during handling.

  In the present invention, the draining means attached to the louver of the metal blind for outdoor use is a mounting frame portion formed in a lateral channel shape in a side cross section provided at the base end side of the louver. Therefore, since it is provided on the base end side of the bottom wall of the louver, it is preferable that there is no drainage that extends the tip of the top wall at the tip end of the louver and forms an eaves shape. There is no problem even if you add it.
