TECHNICAL FIELD The present invention relates to a folding door installed in a building or the like, and in particular, one panel or a plurality of panels connected in a V-shape, an N-shape, a W-shape, or the like. The present invention relates to a blind device for a connecting portion in a folding door in which adjacent panels are connected in series by suspending a sheet in a frame for each unit.

[Prior Art] Regarding the folding door of this type, the present inventors have filed Japanese Patent Application No. 63-72.
In No. 901 (specifically, a horizontal shutter type folding door), the upper hanging doors are connected to each other in a V shape, and one of the split connecting frames is attached to the free end side of the end door. A door unit is formed, and the shutter frame is sequentially hung on each door unit in order to reduce the weight of the hanging work.On the other hand, in this hung state, the divided connecting frames of adjacent door units are fixed together. We have already proposed a device for suspending a horizontal shutter in which a series of folding shutter doors are formed inside the shutter frame.

[Problems to be Solved by the Invention] However, in such a connecting device, as shown in the drawings of the above-mentioned proposed embodiment, a fastener such as a screw or a rivet for connecting the divided connecting frames to each other. May be exposed and catch your eyes.

Here, the connecting frame can generally be formed into a simple shape that is substantially uniform in the longitudinal direction by using an extruded mold material, etc. However, this may damage the overall appearance of the folding door.

Also, when the fastener is exposed and thus visible, if the folding door can be opened from an appropriate intermediate position by unlocking the fastener and dividing the connecting frame. Since there is also a possibility, there is room to add a specific security measure to the connection part.

The present invention has been made in view of such a problem, and by connecting the folding doors that separate and hang the adjacent panels to each other by blindfolding, the folding doors can be connected to improve the appearance and crime prevention. An object is to provide a blindfold device.

[Means for Solving the Problem] The present invention has been completed in view of the above-mentioned object, that is, the present invention is a swing frame between adjacent panels which is flexibly connected to both sides of a joint hinge; and one swing frame. And a connecting means for separating and suspending adjacent panels, which is formed by splitting and is connected by a fastener; and a closed extension that extends from the other rotating frame to the opposite side of the rotating shaft and opens the angle between the adjacent panels. And a connecting member concealing device for the folding door, characterized in that it has a rotating fin facing the fixing member of the connecting means in the state (Claim 1).
And the connecting means for the folding door, which has a connecting means for separating and suspending adjacent panels in which joint hinges are formed separately and connected by a fastener, instead of the connecting means of claim 1. It relates to (Claim 2) and makes them the main points of each.

[Operation] Adjacent panels are made foldable by connecting pivot frames to both sides of the joint hinges so that they can flex and extend.

In addition, the joint hinge or the connecting means for separating and suspending, in which one of the pivoting frames is dividedly formed and connected by the fasteners, the adjacent panels are united one by one or a plurality of V-shaped connected panels. They are separated and hung and then connected.

Further, the rotary fins extending from the other rotary frame to the opposite side of the rotary shaft rotate together with the panel having the rotary frame,
In the closed and extended state of the folding door in which the angle between the adjacent panels is open, the fastener is confronted and concealed by facing the fastener of the connecting means. On the contrary, when the folding door in which the angle between the adjacent panels is closed is in the open bending state (for example, in the state of being stored in the door pocket), this facing is released.

[Embodiment] The present invention will be described more specifically with reference to FIGS. 1 to 3 and 4 showing two different embodiments.
1 to 3 show a folding door 1 provided with a connecting portion blinding device according to the present invention. The folding door 1 is supported on an opening frame 2 so as to be vertically suspended and can be opened and closed in a lateral pulling manner.

The folding door 1 is framed by an aluminum alloy extruded mold material, and a vertically long panel 3 with glass mounted inside is formed into a bellows shape by mutually arranging a first joint hinge 4 and a second joint hinge 5. It is configured by connecting.

On the other hand, above each of the second joint hinges 5 ...
Further, a slack stop 16 is provided on the lower side so as to be engaged with the upper and lower frames 12 and 14 in order when the folding doors are closed, but conversely, when the folding doors are opened, these engagements are sequentially released and the The two-joint hinges 5 ... Separate from the plane of the opening frame and project.

Further, in this example, one of the rotary frames 6 and 6 connected to both sides of the first joint hinge 4 ...
A first member 6a provided with a second member having a glass holding groove 10
The member 6b is divided and formed, and then connected by a fastener 17 such as a rivet (or a screw) to form a connecting means 18 for separating and suspending adjacent panels. As a result, the panel 3 can be sequentially hung in the opening frame 2 in units of a set of two V-shaped connected by the second joint hinge 5.
After this suspension, the first member 6 of the rotary frame formed by division is formed.
a and the second member 6b are connected to each other by a fastener 17 so that the entire panel 3
... are connected together in a series.

On the other hand, one of the side walls 9 extends from the other of the rotary frames 6 and 6 connected to the first joint hinge 4 to the opposite side of the rotary shaft and has a rotary fin 19. is doing. And
The rotating fin 19 rotates together with the rotating frame and faces the fixing member 17 of the separating and suspending connecting means 18 in the closed and extended state of the folding door with an angle between the adjacent panels 3 and 3 (first). See FIG. 2 (B).

On the contrary, in the open bending state of the folding door with the angle between the adjacent panels closed (for example, the storage state in the door pocket portion 21 shown in FIG. 2A) or the intermediate angle state up to this, depending on the angle. The facing of the fixing device is released, and the fixing device 17 can be attached or removed for maintenance.

Next, the opening frame 2 is made of the same aluminum alloy extruded material, is provided with the upper frame 12, the lower frame 14 and the end frames 20 and 20 on the left and right sides to form a horizontally long rectangular shape, and one end frame side is a door pocket. It is provided with the part 21.

The upper frame 12 is provided on the upper side with two shallow groove-shaped first guide rails 22 spaced apart over the entire length in the longitudinal direction thereof.
The first guide rail is provided with a second guide rail 23, which is a slightly elongated groove, below the first guide rail, and the second guide rail 23 allows the second joint hinges 5 ... The horizontal door pulley 15 is made to run, and the back side of the door pocket 2 is cut out and cut out, and the guide rail outlet 25 is provided by this cutout portion. In this example, the exit 25 is closed by a blind strip 26 that can be moved up and down when the folding door is closed.

That is, the blindfold strip 26 is a plate member having substantially the same length as the exit 25, and is provided with a pair of front and rear small door wheels 27 at two left and right sides thereof, and the folding door presses the engaging shaft 28 on the door pocket side. By doing so, the small door pulley 27 is guided to the inverted V-shaped inclined guide 30 of the block 29, so that the blindfold strip 26 is configured to be inclined and projected. In addition, the height of the height of protrusion and depression is set from the lower end of the second guide rail 23 to a little above the horizontal door roller 15.

On the other hand, the lower frame 14 includes an outer fixed frame 31 and an inner U-shaped movable frame 32 having substantially the same length as that of the lower fixed frame 31, and a groove-shaped lower guide rail 33 is provided in the movable frame 32. The horizontal frame 13 of the joint hinge is made to run, and the movable frame 32
Is slidably projected and retracted with respect to the fixed frame 31, so that when the folding door is closed, the deflection stopper 16 is fitted into the lower guide rail 33 and the rear side fins 34 of the movable frame.
Is inserted into the receiving groove 35 provided in the anti-flare.

The means for projecting and retracting the movable frame 32 is the same as that for the blindfold strip 26 except that the length thereof is different.

By the way, the guide rail exit 25 provided on the upper frame 12
Is the total length of the folding allowance 1 of the folding door and the lateral width 2 of two panels, and the length corresponding to the folding allowance 1 from the end frame 20 of the door pocket portion 21 having this length. Therefore, in the present example, the fixing panel 36 fixed in a fit-and-kill form is provided.

The fixing panel 36 is moved from the center of the upper and lower frames 12 and 14 and the end frames 20 and 20 to the front side and screwed to these so that the fixing panel 36 is not caught in the in-plane position of the opening frame 2. At the opening side end frame 37 of the panel 36 (that is, a fixed position separated from the end frame 20 by the folding margin of 1 minute), the end frame 37 is formed into an inverted L shape from the position of the end frame 37 toward the in-plane position. The contacting projection 38 is integrally provided so as to project over the entire length in the longitudinal direction so as to be freely contactable with the rotating fins 19 of the rotating frame.

As a result, in addition to the blindfolding of the fasteners 17 of the connecting means for separating and suspending, the rotating fins 19 of this example are described in detail in Japanese Patent Application No. 1-225053 relating to the present inventors' proposal. However, when the folding door is closed, it also has the function of forcibly rotating the swinging frame 6 which has reached the fixed position to make the closing and extending of the panel 3 smoother. Of course, on the contrary, it does not hinder the open refraction.

Reference numeral 39 in the drawing denotes a nylon silencing block provided at the upper and lower ends of the abutting protrusion 38 so as to slightly project toward the end frame. Although not shown, the abutting protrusion 38 engages with the letter-shaped engaging ridge 41 toward the front side of the end moving frame 40 of the folding door which has been completely closed to seal the space between the folding door 1 and the fixed panel 36. I'm trying to stop. Further, in the figure, reference numeral 42 is a traveling frame at the front end on the door-stop side which is also provided with a supporting door car, and 43 is drawn out and rotated in the lower frame 14 so as to rotate the lower guide rail 3
Dust-proof groove lid strips for closing 3 and 44 similarly denote movable frame projecting / withdrawing blocks in the lower frame 14, respectively.

Next, in the embodiment shown in FIG. 4, in place of the connecting means 18 in which the rotary frame is divided and formed, first and second joint hinges 4 each having a circular projection 7 as a rotary shaft are provided. Second member 4
It is different from the previous embodiment in that it has a connecting means 18 'for separating and suspending adjacent panels, which is divided into a and 4b and is connected by a fastener 17 such as a rivet (or a screw).

The rotating fin 19 of this example extends from one of the rotating frames 6 and 6 to the opposite side of the rotating shaft, and is separated in the above example in the closed and extended state in which the angle between adjacent panels is opened. It faces the fastener 17 of the hanging connecting means 18 '.

Since the other points are the same as those of the previous embodiment, the same reference numerals are given in the drawings and the folding door as a whole is not shown.

Although not shown, when the folding door is closed and extended along the curved guide rail, the rotating fins are not in a state in which the adjacent panels are extended in series, but in a state in which a slight bending angle is left. Face the fastener with. In the case where the joint hinge is opened and closed along a special curved guide rail such as an S-shape, the joint hinge is proposed by the present inventors in Japanese Patent Application No. 63-72902 for the purpose of facilitating the opening and closing. It is more preferable to use a device capable of rotating three or more axes.

Further, the folding door is a horizontal pull type which is hung above the opening frame as in the above embodiment, and a panel shutter which can be folded in the vertical direction (for example, a wire hanging type or the inventors of the present invention Japanese Patent Application No. 1-47560). The blindfold device can also be used for the carry-on type, etc.

On the other hand, the connecting means for separating and suspending the adjacent panel may be provided on the second joint hinge that can be detached from the plane of the opening frame or the rotating frame connected to the second joint hinge. In particular, as in the above-mentioned Japanese Patent Application No. 63-72901, when a door roller is provided in the center of the width of the panel and the door is suspended in the opening frame, the folding door has each joint hinge (and each hinge connected thereto). Since the movable frame) is alternately projected and folded to the front side and the back side, the structure is naturally taken.

As a matter of course, the arrangement position of the connecting means for separating and suspending the adjacent panels is not only every two panels connected in a V shape like the embodiment, but also every one panel according to the weight limit of the suspending work, etc. Alternatively, N-shaped (3 sheets), W-shaped (4 sheets), and the like may be arranged with a large number of connected panels separated from each other.

Further, the fasteners in the connecting means for separating and suspending,
Various well-known items such as rivets, screws, bolts and nuts can be selected. By replacing these rivets and the like with a locking device in some of the connecting means, it is possible to open and close and lock the folding door from the beginning so that the blindfolding device is partially omitted. Can be done.

As will be understood from the above, in carrying out the present invention,
The specific shape, structure, size, material, number of members, arrangement and relationship of joint hinges, pivoting frames, fasteners, connecting means for separating and suspending, pivoting fins, and the like, and the type of folding door are the same as those of the above invention. Various changes can be made without departing from the gist.

[Effects of the Invention] The folding unit of the folding door according to the present invention is configured according to the above-mentioned gist, and the separate hanging connecting means opens the panels one by one or a plurality of V-shaped panels. In addition to being able to connect these after hanging in the frame to reduce the weight of the hanging work, it also has a rotating fin that rotates in conjunction with the opening and closing operation of the folding door by extending it from the rotating frame. The fixing means of the connecting means for separating and suspending are made to face each other in a closed and extended state in which the angle between the adjacent panels is opened, and therefore, when the folding door is closed, these fixing means are blindfolded by themselves. This makes it possible to simplify the appearance of the closing surface of the folding door, and at the same time, the fastener is not removable and the closed folding door is prevented from splitting and opening from the middle position, thus improving crime prevention. To be able to .
