Abstract

<P>PROBLEM TO BE SOLVED: To provide a shutter box which can prevent streaky dirt thereof caused by rainwater to a possible extent, and can improve its practical using sense. <P>SOLUTION: According to the structure of the shutter box, rainwater containing dust and flowing from a top surface 1a of the shutter box 1, flows down on both sides of a rainwater storage section 2 without dripping along a front surface of the shutter box as rainwater streaks, and therefore the front surface of the shutter box 1 can be prevented from fouling with streaky dirt. Thus a building using the shutter box 1 does not show stain, and therefore cleaning of the shutter box 1 does not take much time and trouble, leading to excellent maintainability of the same. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a shutter box.

  As shown in Patent Document 1, a shutter provided in a garage or a sweep window provided in a residential building is accommodated, and is provided so as to protrude from the outer wall on the upper side of an opening such as a garage or a sweep window. The top surface of the shutter box had a gentle water gradient.

In this way, in the case of a shutter box provided with a gentle water gradient on the top surface and protruding from the upper side of the opening, if it rains, rain stripes hang down the front of the shutter box, and In order to cause inconvenience such as remaining as dirt, Patent Document 2 discloses a draining portion extending from the top surface so as to protrude further outward than the front surface of the shutter box, and the extending tip is further bent downward. There has been disclosed a shutter box that can prevent the occurrence of streak-like dirt.

  In general, in the case of rain, wind is accompanied, and depending on the direction and strength, even in the shutter box shown in Patent Document 2, avoid the rain water being blown to the front of the shutter box by the wind blowing simultaneously with rain. The sprayed rainwater may cause streak stains on the front of the shutter box.

  Further, when the shutter is opened and the garage enters and exits after the rain has stopped, there is a realistic bad feeling that rain water falling from the draining portion to the ground prevents the entry and exit of the garage.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a shutter box that can prevent the occurrence of streak stains caused by rainwater as much as possible and has an improved realistic feeling of use. .

  In order to solve the above problems, a shutter box of the present invention is provided on the upper side of the opening so as to protrude outward from the outer wall, and has a shutter box front upper end formed with a water gradient on the top surface, and a shutter box ceiling. A rainwater storage part is provided in a region where the front end of the surface intersects.

  The rainwater storage part is formed by bending the rainwater storage side part formed by bending the front end of the top surface of the shutter box downward, and the rainwater storage bottom part formed by bending the lower end of the rainwater storage side part toward the front surface of the shutter box. Thus, the rainwater storage bottom may be continuous with the front surface of the shutter box, and the front upper end of the shutter box may be extended above the rainwater storage bottom.

The rainwater storage part is formed by bending the rainwater storage side part formed by bending the front end of the top surface of the shutter box downward, and the rainwater storage bottom part formed by bending the lower end of the rainwater storage side part toward the front surface of the shutter box. The rainwater storage bottom may be continuous with the front surface of the shutter box, and a weir may be attached to cover the continuous corner along the continuous corner between the front upper end of the shutter box and the rainwater storage bottom. .

  A locking portion for the dam portion may be integrally formed at a continuous corner portion with the rainwater storage bottom portion, and the dam portion may be an elastic member that is elastically locked to the locking portion.

  The rainwater storage part is formed by bending the rainwater storage side part formed by bending the front end of the top surface of the shutter box downward, and the rainwater storage bottom part formed by bending the lower end of the rainwater storage side part toward the front surface of the shutter box. Thus, the rainwater storage bottom portion can be continuous with the front surface of the shutter box and can be provided with a slope that slopes downward from the upper front end of the shutter box toward the lower end of the rainwater storage side portion.

  At least one of both side ends of the rainwater storage part may be opened, and a capillary groove or rain gutter continuous with the rainwater storage part may be provided on at least one of both side surfaces of the shutter box.

  According to the shutter box of the present invention, rainwater containing dust from the top surface of the shutter box is stored in the rainwater storage section without dripping as rain streaks on the front surface of the shutter box, and appropriately on both side ends of the rainwater storage section. Since it flows down from at least one of the open cuts, it can completely prevent the front of the shutter box from becoming streaked, and when the rain stops, the shutter is opened and the garage enters and exits. There is no problem that rain water falling from the top of the shutter box to the ground prevents entry into and exit of the garage, improving the feeling of use.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
