Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an airtight structure for a panel shutter, and more specifically, the invention relates to an airtight structure for a panel shutter, and more specifically, a structure in which each panel constituting the shutter curtain maintains airtightness when the opening is closed. This invention relates to an airtight structure for panel shutters that allows panel shutters to be vertically adjacent to each other.

[Prior Art] In conventional buildings, when air conditioning equipment is installed, an airtight structure is adopted at the boundary between the outdoors and the indoors, and airtight panel shutters are also known. For example, in Utility Model Publication No. 56-46446,
As a technique for tightly engaging the upper frame and the lower frame of the panel, a pair of legs 1c are provided at the lower end of the panel, each extending in a direction parallel to the front and rear surfaces.
and 1d, and a recess 1f is formed between the two, and a protrusion 1g having a shape corresponding to the recess 1f is provided at the upper end of the panel, and contact surfaces 1h and 1i are formed at both ends of the protrusion 1g. 1g engages with the recess 1f, the legs 1c and 1d come into contact with the contact surfaces 1h and 1i, respectively, and the technical content is disclosed to bring the panels into close contact not only in the vertical direction but also in the left-right direction (front-back direction). (column 4, lines 14 to 20, and column 6, lines 4 to 11)
(see line).

However, in the panel shutter having an airtight structure as described above, as is clear from FIGS. 4a and 4b of the publication, when the shutter is closed, there is a step-like structure between the legs 1c and 1d of the upper panel 1 and the upper end of the lower panel 1. There is a risk that fingers or the like may be caught between the contact surfaces 1h and 1i.

[Problem to be solved by the invention] The present invention was devised in view of the above-mentioned actual situation in order to eliminate the drawbacks of the conventional method, and its purpose is to ensure safety when closing. In addition, the panels can be placed vertically adjacent to each other to maintain airtightness in the closed state, and when it rains, the top surface of the airtight member can function as a rain gutter. It's about trying to provide structure.

[Means for Solving the Problems] In order to solve the above problems, the technical means adopted by the present invention is to connect vertically adjacent panels such that they are spaced apart in an open position and stacked in a closed position. In the panel shutter, an upper cover piece is formed on the upper edge of one side of each of the panels to protrude upward and cover the vicinity of the lower surface of the one side of the panel adjacent to the upper side when the opening is closed. A lower cover piece is formed on the lower edge of the other side of the panel to protrude downward to cover the vicinity of the upper side of the other side of the lower adjacent panel, and the upper cover piece and the lower face of the one side of the panel and A space is formed between the lower cover piece and the upper surface of the other side of the panel, and an airtight member is provided in the longitudinal direction of the corner between the upper cover piece and the upper surface of the panel, so that the airtight member is adjacent to the upper side when the opening is closed. This is characterized in that the airtight member is pressed against one side of the lower surface of the panel.

[Function] Therefore, according to the present invention, when the opening is closed, the vicinity of the lower surface on one side of the upper adjacent panel is covered by the upper cover piece, and the upper surface on the other side of the lower adjacent panel is covered. Since the vicinity is covered by the lower cover piece, there is no risk of fingers or fingers getting caught, and the airtight member provided at the corner of the upper cover piece and the top surface of the panel is pressed against one side of the bottom surface of the panel adjacent to the top. Therefore, in the closed state, each panel is vertically adjacent to each other while maintaining airtightness. In addition, the space formed between the lower surface of one side of the upper panel and the upper cover, which is covered by the upper cover when closed, functions as a rain gutter when it rains, so it is possible to shut off the rain while maintaining airtightness. Can be performed well.
