Description

  The present invention relates to a folding door configured by connecting a plurality of panels and having a louver function. And as the use, it can be used, for example as a shutter installed outside the window of a house, a partition installed inside and outside the building, and further as a shutter installed at the store entrance.

  A general folding door has a plurality of panels, and each panel is connected via a joint. The front door is opened by folding each panel, and the front door is opened by extending each panel. It can be closed. By the way, each panel is connected via a joint, a suspension wheel is attached to the upper end of the main joint and suspended from the upper rail, and a slider is attached to the lower end and loosely fitted to the lower rail. Therefore, when the folding door is folded, the secondary joint is kicked out from the upper and lower rails.

  In this way, with folding doors connected via a main joint and a sub-joint, the operation of each panel is not constant when opening and closing, and a space is created between adjacent panels for ventilation and lighting. I can't. That is, it is impossible to provide a louver function from the panel connection structure. Therefore, folding doors are known in which the panels are connected via links, and the folding doors can be rotated to form a space between the panels with the frontage closed.

  “Blind” according to Japanese Utility Model Publication No. 46-33320 has a required number of shielding plates in which left and right edges are bent in different directions to form joint edges, and upper and lower ends are fixed with L-shaped connecting pieces. Side by side, forming the shielding body that sequentially connects the required number of shielding plates in a telescopic manner as if the center of one connecting piece and both ends of each connecting piece parallel to both sides of the connecting pieces are connected together. The outer edge of the shielding plate facing the shielding body is hinged so that the sealing plate can be folded inward without forming a joining edge, and a bearing is provided on one side of the required number of upper connecting pieces. The guide ring is pivotally attached to the bearing body, and a support body is pivotably suspended from one side of the required number of the lower connecting pieces, and the bearing opening of the bearing body is Rolls are accommodated so that they can roll freely.

The “blind shutter” according to Japanese Patent Application Laid-Open No. 2000-2060 has a structure that itself has a housing for rain, snow and dust.
Therefore, a shutter frame for fitting a blind shutter is formed, and a casing is integrally formed on the upper side of the shutter frame. A guide rail portion having a downward slit is formed integrally with the housing, and a guide pin at the upper end of the slat is inserted into the slit, and a roller is connected to the guide pin. A guide rail portion having a slit is integrally formed on the lower side of the shutter frame, and a guide pin at the lower end portion of the slat is inserted into the slit to prevent the guide rail portion from coming off.

The “blind shutter installation structure” according to Japanese Patent Application Laid-Open No. 2005-105515 improves the mounting workability of the upper frame of the blind shutter.
Therefore, the shutter guide frame fixed to the outer wall of the window opening formed in the building constitutes the upper frame constituting the upper side, the left and right vertical frames constituting the side, and the lower side. And a lower frame. The upper frame includes a frame main body that supports the blind shutter and a fixing portion that fixes the frame main body to the outer wall. Both of these are constituted by separate bodies, and the frame body has a structure in which a housing is integrally formed.

These blind mechanisms are unstable during opening and closing operations, have low strength against wind pressure, and have a small ventilation / lighting area (space) when louvers are not sufficient. Also, when fully closed, each panel does not fit flat, and rattling occurs. In addition, there are problems such as poor workability (panel installation from the side) and insufficient waterproofing around the frame when mounting the frame.
"Blind" according to Shoko Sho 46-33320 "Blind shutter" according to Japanese Patent Laid-Open No. 2000-2060 “Blind shutter installation structure” according to Japanese Patent Application Laid-Open No. 2005-105515

  Thus, the conventional blind mechanism has the above problems. The problem to be solved by the present invention is these problems, and provides a folding door device with a louver function that is stable in opening and closing operation, has no backlash of each panel, has excellent workability and is waterproof.

  The folding door device according to the present invention is a folding door provided with pantograph type link mechanisms at the upper and lower ends, that is, a pantograph type link constituting the link mechanism is attached to the upper and lower ends of a plurality of panels. Therefore, the folding door can be opened and closed with the expansion and contraction of the link mechanism. For this purpose, a suspension wheel is attached to one side end of each panel, and a slider is provided below.

The suspension vehicle is suspended from the upper rail and the slider is loosely fitted to the lower rail, the link mechanism expands and contracts along the upper and lower rails, and the panel attached to each link of the link mechanism changes its orientation. Move and the folding door opens and closes. By the way, although the said structure as a folding door provided with the pantograph type link mechanism is the same as the past, in this invention, it has the following characteristics.
(1) Louver mechanism.
The front end of the folding door has a handle bar with a door rod, but a louver guide is attached to the top and bottom of the door rod, and the link door end of the folding door is slidably guided by the louver guide. Yes. Therefore, if the tip of the link is moved along the louver guide with the handle bar and the door end bar fixed at fixed positions, the folding door can be brought into the louver state. That is, when the link mechanism is contracted, each panel rotates and enters a louver state. However, the present invention is not limited to the louver mechanism using this louver guide, and two arms that rotate while being connected to each other may be used.
(2) The handle door side panel provided on the panel is provided with a handle, and if the handle is operated by placing a hand on the handle, the panel of the folding door rotates to be in a louver state.
(3) The key attached to the handle and the French drop handle are attached with a key and a French drop. Therefore, if the lock is applied, the handle bar can be locked to the vertical frame of the frame, and if the French drop is lowered, the slider that engages the tip of the link and slides the louver guide is locked. Therefore, if the French drop is descending, it will not be in a louvered state. However, if the key is removed, the folding door will fold regardless of the lift position of the French drop.
(4) Flat storage of each panel when fully folded.
The ends of the links constituting the link mechanism are notched, and when the link mechanism is extended, the notch portions of the adjacent links are engaged with each other to form one link width. The panel side end is also cut out in correspondence with the cutout portion of the link. Therefore, each panel to which the link is attached becomes one plane, and the folding door in the fully closed state becomes flat.
(5) A divided structure of the upper frame constituting the frame.
The upper frame on which the folding door is mounted has a two-piece structure of an upper frame body and an auxiliary upper frame. The upper frame body is fixed to the building wall surface, and the auxiliary upper frame is assembled to the upper frame body. A metal fitting is fixed to the building wall surface, and the upper frame and the lower frame are engaged and attached to the metal fitting.
(6) A door toe guide is attached to the upper and lower ends of the door toe, and the door toe guide is engaged with guide pieces provided on the upper frame and the lower frame.

  In the folding door device according to the present invention, since a plurality of panels are attached to the pantograph type link mechanism, the panels are folded and overlapped. And since it is provided with a louver mechanism, each panel can be rotated with the folding door closed, and a louver state can be obtained. Even if the key is locked and the folding door is closed when the key is locked and the folding door is closed, the panel is rotated by operating the louver mechanism and the panel is rotated, and ventilation and lighting are performed as a louver state. I can do it.

  The folding door is provided with a door toe integrated with the pulling handle, and when the folding door is extended and the panel rotates, the space formed between the pulling handle and the tip panel is It can be blocked by a toe fence. In addition, since the front end of the link constituting the link mechanism is notched and each panel side end is also notched, the connected link is notched when the folding door is extended and closed. And each panel fits in one plane. That is, in the closed state, the folding door surface has no irregularities and becomes a flat surface.
