Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drainage structure for an architectural shutter case.

[Problems to be solved by the prior art and the invention] Generally, in architectural shutters, a shutter curtain wound up inside a shutter case provided above is passed through a feeding opening provided on the bottom side of the shutter case. The opening is closed by being guided by the left and right guide rails. The opening is provided with a clearance so that the shutter curtain can pass through it smoothly, but when the shutter curtain is rolled up and the opening is open, the seat plate provided at the lower end of the shutter curtain will close to the opening. It is designed to come into contact with and close the feeding opening. However, when the shutter curtain at the opening is half open or fully closed, dust and rainwater blown up by the wind can blow into the case from the clearance between the outlet provided on the bottom of the shutter case and the shutter curtain. Also, when a shutter curtain with rainwater adhering to it is rolled up and stored inside the case, rainwater may fall into the case. As a result, as shown in FIG. 2, conventionally, dust and rainwater are accumulated inside the shutter case without being discharged outside the case, and the end of the case plate 4, which is installed between the case side plates and forms the feeding opening, It accumulates at the corner of the joint between the lintel 3 and the end of the case plate 4, which is used to fix the shutter, and causes corrosion of the shutter case, causing corrosion to the lintel part of the shutter case plate in a relatively short period of time. It was becoming a problem because of the holes.

[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a drainage structure for architectural shutter cases that can eliminate these drawbacks. At the end of the case plate, which is provided on the bottom side of the shutter case and forms the opening for letting out the shutter curtain along the left and right guide rails, protrusions are placed at appropriate intervals toward the inside of the shutter case. At the same time, a linen material is placed and fixed on the protruding portion along the feed-out opening, so that the inside of the shutter case and the feed-out linen are connected between the end of the shutter case plate that forms the feed-out port and the lower surface of the linen material. It is characterized by forming a drainage path leading to the mouth.

With this configuration, the present invention is capable of preventing corrosion of the shutter case by allowing dust and rainwater that have entered the inside of the shutter case to be quickly discharged to the outside of the case.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a shutter case installed above the building opening, and 2 is a shutter case 1.
The shutter curtain 3 opens and closes the opening by being wound up and unwound inside the case 1. Reference numeral 3 is a lintel material installed between the side plates inside the case 1 and fixing the lower end surface of the case. It is designed to form one side edge. 4 is a case plate of the shutter case, and 5 is a fixing screw that fixes the lintel 3 and the lower end of the case plate. Reference numeral 6 denotes a protrusion, which is provided at the end of the case plate 4 that forms the opening 8 for the shutter curtain 2, protrudes toward the inside of the shutter case 1, and is formed by pressing or the like. They are arranged along the shutter curtain delivery opening 8 at appropriate intervals. Then, by placing the lintel material 3 on the protruding part 6 and attaching and fixing the lintel material 3 from below the protruding part 6 with the screws 5, the lower surface of the lintel material and the end of the case plate 4 on the feeding port 8 side A drainage path (arrow B) leading to the inside of the case 1 and the feeding port 8 is formed between the surfaces. In addition, 7 is the one in which the edge of the shutter case plate 4 that forms the shutter curtain delivery opening 8 is curled downward, so that rainwater discharged from the case 1 can easily flow away. . In the embodiment of the present invention configured as described above, rainwater and dust blown from the outlet 8,
Alternatively, rainwater that has been rolled up while adhering to the shutter curtain 2 may enter the case 1 as the shutter curtain 2 is rolled up, and the lintel material 3 inside the case 1 and the case plate 4 may be joined together due to vibrations etc. during winding up. Even if the lintel material 3 moves and accumulates in the corner, it is placed and fixed on the end surface of the case plate 4 via the protrusion part 6 arranged along the feeding port 8 at an appropriate interval. A drainage path (arrow B) with a height of Corrosion of the case plate 4 due to rainwater is prevented. Also,
Since the lintel 3 and the end of the case plate 4 are fixed from below the outer surface of the case 1 of the protrusion 6, the screw head does not protrude from the case plate 4 as in the conventional case, and the appearance is improved. is also preferable.

[Operations and Effects] In summary, since the present invention is constructed as described above, dust and rainwater that have entered the case are absorbed between the end of the case plate, which forms the opening of the shutter curtain, and the lower surface of the lintel material. The water is quickly discharged outward from the shutter curtain delivery portion through the drainage path formed in between, and corrosion of the shutter case can be effectively prevented.

Claims (1)

[Scope of utility model registration request] At the end of the case plate, which is provided on the bottom side of the shutter case and forms the feeding opening for feeding out the shutter curtain along the left and right guide rails, protrusions are arranged at appropriate intervals toward the inside of the shutter case. At the same time, a linen material is placed and fixed on the protruding portion along the feeding port, so that the interior of the shutter case and the bottom surface of the linen material are located between the end of the shutter case plate forming the feeding port and the lower surface of the linen material. A drainage structure for an architectural shutter case characterized by forming a drainage path leading to a feeding opening.
