  In the second aspect of the present invention, in the underfloor ventilation port according to the first aspect of the present invention, the shape of the blades as viewed from the right side of the upper end and the lower end of the blade is the former with a reverse “K” shape, When the blades bend down and close the opening, the lower end of the upper and lower adjacent blades has the lower end of the lower one. It is configured to overlap the upper end.

  According to the underfloor vent of 1 of the present invention, it is possible to obtain an underfloor awakening effect while preventing the entry of insects and the like, and when necessary, the underfloor vent can be easily opened and closed with a very simple operation. In addition, it is possible to prevent blowing rainwater.

  According to the underfloor ventilation port 2 of the present invention, it is possible to more reliably prevent rainwater from blowing.

  The underfloor vent of the present invention basically has a frame structure with an opening that penetrates the inside and the back, an openable / closable lid on the front side of the opening, and an insect-proofing on the back side of the opening. An underfloor ventilation opening provided with a perforated plate or a net-like member for use in an underfloor ventilation opening used in a ventilation opening opened in a notch shape in a rising portion of a building foundation. A plurality of lateral blades arranged vertically adjacent to cover the opening on the front side of the opening, each of which is configured by a lateral blade that opens and closes the opening by undulating each other Is.

  As described above, the underfloor ventilation port has a frame structure and is configured by a quadrilateral frame. Basically, the quadrilateral frame with the frame structure, like the conventional frame, secures a predetermined opening space so that the upper part abuts on the lower part of the base of the building, and the lower part is the base of the building foundation. It is placed on the bottom of the ventilation opening that is opened in a notch shape at the rising part. For this reason, the vertical dimension corresponds to the dimension between the bottom surface of the base of the building and the bottom surface of the rising part of the foundation, and the width is also the dimension between both side surfaces of the ventilation opening, as in the conventional case. Configure to the corresponding one. The depth is also set to an appropriate dimension corresponding to the width of the foundation of the building and the rising part of the foundation.

  Further, the material of the quadrilateral frame having the frame structure is not particularly limited as long as necessary strength and durability can be secured. However, a stainless steel plate is easily available and can be used after being processed into a predetermined shape. is there.

  The perforated plate or the net-like member for insect repellent, as well as the conventional one, can prevent the passage of insects and is intended to ensure an appropriate flow of air. As long as it is provided with a hole and fits the purpose, the shape of the hole is not limited. In addition, the perforated plate or net-like member for insect repellent is suitable because it can be easily obtained and can ensure the required durability and the like, as with the quadrilateral frame having the frame structure. These perforated plates or net-like members can be attached to the back surface of the quadrilateral frame with screws or the like.

  The lid body is configured by arranging a plurality of blades arranged in the horizontal direction in the vertical direction, and the blades adjacent to each other in the vertical direction are arranged with a part of each upper and lower end overlapping each other. .

  Each of the blades shall be constructed so as to undulate in conjunction with each other, and when they stand up and become horizontal, the blades of each of the blades are arranged so as to fit within the quadrilateral frame of the frame structure. The width is smaller than the depth of the quadrilateral frame. For this reason, the width of the blades and the number to be arranged in the vertical direction should be determined in consideration of the depth and vertical dimensions of the quadrilateral frame.

  In addition, each blade can adopt a simple strip-shaped plate material, but when the shape of the upper end and the lower end is viewed from the right side, the former is an inverted “<” shape, and the latter is When the front side of the opening of the quadrilateral frame is closed by lowering each blade, the lower end of the upper one of the blades adjacent to each other in the shape of a "<" The part is preferably arranged so as to overlap the upper end of the lower part.

  As a mechanism for moving the blades up and down while interlocking with each other, any configuration that can achieve this purpose can be adopted. For example, the following simple configuration can be employed.

  Each of the blades is mounted around a horizontal rotating shaft through mounting pieces arranged at both left and right ends so as to be able to turn up and down together with the rotating shaft. The horizontal rotation shafts are attached to the side plates of the quadrilateral frame in multiple stages corresponding to the arrangement of the blades, and the attachment pieces are fixed to the rotation shafts. . Similarly, a rotating member that rotates together with the respective rotating shafts is also attached to the inner central side of the respective rotating shafts. The other end of each of the rotating members arranged in multiple stages is engaged with an upright connecting member that connects all the rotating members at the end, and the upright connecting member is connected to the connecting member from the front side of the opening. Attach an operable control lever. The upright connecting member is fastened not by welding but by a bolt and a nut so that the predetermined direction can be maintained even if each of the rotating members rotates. Therefore, by sliding the operation lever up and down, the upright connecting member is also displaced up and down, and each rotating member is raised and lowered around each rotation axis. In association with this, the mounting pieces are caused to undulate and rotate around the respective rotation shafts, whereby the corresponding blades are undulated and rotated, and the openings can be freely opened and closed.

  Therefore, according to the underfloor ventilation port of the present invention, it is installed in the ventilation opening opened in the notch shape of the rising part of the building foundation as follows to prevent the invasion of insects etc. and easy operation according to the situation Therefore, it is possible to prevent rainwater from being blown by covering with a lid.

  The frame-shaped quadrilateral frame is installed in a ventilation opening that is open at a rising portion of a building foundation. Insert mortar between the lower part of the quadrilateral frame and the bottom surface of the ventilation opening as necessary to adjust its height so that the upper part comes into contact with the lower part of the building base. To do. If necessary, a part between the upper part and the lower part of the building base may be filled with mortar. Further, a mortar is filled between the side of the quadrilateral frame and the side of the ventilation opening so as to eliminate a gap.

  As described above, when the underfloor ventilation port of the present invention is installed in the ventilation opening that is opened at the rising part of the building foundation, the blade is raised by the operation lever operation or the like (the horizontal state is set). ), The opening is opened, and air permeation can be ensured while preventing the entry of insects and the like by the insect-proof perforated plate or the net-like member disposed on the back surface.

  When there is a possibility of rainwater blowing through the underfloor vent in a typhoon or the like, the blades are bent down (turned downward) by operating the operation lever or the like, and the opening of the quadrilateral frame Will be closed. At that time, as described above, among the blades adjacent to each other in the vertical direction, the lower end portion of the upper side thereof overlaps the upper end portion of the lower side of the blade, so that it is possible to reliably prevent rainwater from blowing in. .
