Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slat connection structure in a door panel formed by combining a plurality of slats made of steel plates.

[Problems to be solved by the prior art and the invention] Generally, hanging type sliding doors, so-called hanger doors, are often used to open and close large openings in buildings. Since this is a large opening, it is required to have sufficient strength and be easy to open and close. In response to such demands, so-called angle doors emerged, in which steel plates of appropriate thickness are connected in a series to form the door surface plate, and angle members are welded or riveted around the back side and diagonally. However, it was time-consuming to assemble, and the door itself was heavy due to the use of many angle members, making it difficult to open and close.

Therefore, for example, as shown in FIG.
A plurality of slats 16 are formed by bending the slats 16 into a substantially U-shape by roll molding so that the slats 16 have a diameter of 5, and the plurality of slats 16 are arranged so that the first rising side 14 and the second rising side 15 are in contact with each other. It is proposed that a strong door panel can be formed without using angle materials by integrally connecting these with bolts, welding, etc. However, this method still requires bolts or welding to connect the slats, so there is a problem in that the workability is extremely poor.

On the other hand, as shown in Japanese Unexamined Utility Model Publication No. 53-51016, a structure in which the rising sides of adjacent slats are interlocked and connected to each other has been proposed. In the folded part formed at the corner between the rising edge,
An interlock connection is achieved by forcibly fitting an engagement recess formed in a corner between the face plate portion and the other rising edge into the tip of one rising edge while supporting the tip of the other rising edge. It's getting old. However, in this case, when the forcible fitting is performed, the engagement recess is forcibly rubbed against the tip of the folded part, so the coating on the tip of the folded part peels off and the metal surface is exposed directly to the outdoors. There is a problem with storing
If left as is, it would not only have an unfavorable appearance, but would also suffer from early rusting and impaired durability.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a connecting structure for slats in a door panel that can eliminate these drawbacks. A plurality of slats each having first and second rising sides bent in a substantially U-shape toward the indoor direction are brought into contact with each other with the first and second rising sides of adjacent slats. In this way, in the door panel formed by connecting the face plate portions in a substantially flush manner, first and second locking grooves that are fitted and locked to each other are formed in intermediate portions of the first and second rising sides, respectively. On the other hand, at the tip of the first rising side, a first bent side is formed which is bent at a substantially right angle toward the second rising side of the adjacent slat. , which is further folded back into a substantially U-shape toward the face plate side to form a first folded side that constitutes a first hook-shaped portion together with the first folded side. A second bent side is formed at a substantially right angle in the direction of the first rising side of the slat, and the tip of the second bent side includes:
A second folded side is formed by being folded back into a substantially U-shape on the face plate side and constitutes a second hook-shaped portion together with the second folded side, and each of the first and second folded sides and the folded side The dimensional relationship between the second folded side and the second folded side is approximately equal to the opposing distance between the tip of the first folded side and the first rising side, but and the first folded side, and the length of the second folded side is set to be slightly larger than the inner dimension between the end of the first folded side and the first rising side. The second hook portion is set so that it is larger than the interval but smaller than the length of the first folded side, and the second hook-shaped portion is set to be larger than the length of the first folded side, so that the adjacent slats are arranged at approximately right angles. The tip is fitted between the opposing sides of the first rising side, and from this fitted state, the corner portion of the second rising side and the second bent side is brought into contact with and supported by the first rising side, and the adjacent slat is By relatively rotating the slats, the second hook-shaped part is forcibly fitted into the first hook-shaped part, so that the face plate parts of adjacent slats are interlocked so that they are substantially flush with each other. It is characterized by this.

With this structure, the present invention forms a door panel by interlocking a plurality of slats together, but the slat surfaces are damaged and the paint film peels off when interlocking. This was done to prevent this from happening.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, 1 is a slat, and the door panel of door A is formed by stitching together a plurality of slats 1 as will be described later.
2 and 2a are vertical frames of door A, 3 and 4 are upper and lower frames, one vertical frame 2 is a commercially available standard C-type channel material, and the other vertical frame 2a
Although it is a substantially C-shaped channel material, one side on the outdoor side is formed to be long so as to be in close contact with the first rising side 10 of the slat 1, which will be described later. Also, 7 is door A
The hanger roller 7 is installed on the upper surface of the upper frame 3 to suspend the
The door A opens and closes from side to side by rolling while being guided by an upper guide rail 8 provided on the building side. Furthermore, 5 is a guide provided to hang down from the lower surface of the lower frame 4, and the guide 5 is connected to a lower guide rail 6 provided on the floor surface.
It is designed to loosely fit into the door A and guide the left and right opening and closing of the door A.

The slat 1 is formed by roll-forming a decorative steel plate with a thickness of about 1 mm, for example, and is shown in an enlarged view in FIG. Here, 10 is a face plate part, and on both left and right sides of the face plate part 10, first and second rising sides 11 and 12 are bent in a substantially U-shape toward the indoor direction,
Then, by bringing the first and second rising sides 11 and 12 of the adjacent slats 1 into contact with each other, the face plate portion 10 becomes substantially flush, forming a door panel. , second rising edge 1
First and second locking grooves 11a and 12a, which fit and lock each other, are formed in intermediate portions of the first and second locking grooves 1 and 12, respectively. Further, a first bent side 11b is formed at the tip of the first rising side, and is bent at a substantially right angle toward the second rising side 12 of the adjacent slat 1. A first folded side 11d is further folded toward the face plate 10 side into a substantially U-shape and forms a first hook-shaped portion 11c together with the first folded side 11b. On the other hand, a second bent side 12b is formed at the tip of the second rising side 12, and is bent at a substantially right angle toward the first rising side 11 of the slat 1. A face plate portion 1 is further provided at the tip of the side 12b.
The second bent side 1 is folded back into a substantially U-shape on the 0 side.
A second folded side 12d, which together with 2b constitutes a second hook-shaped portion 12c, is formed. Further, the dimensional relationship between the first and second bent sides 11b, 12b and folded sides 11d, 12d is set as follows. In other words, the outer dimension m between the second folded side 12d and the second folded side 12b is slightly smaller than the facing distance p between the tip of the first folded side 11d and the first rising side 11, The inner dimension q is set to be slightly larger than the inner dimension q between the first bent side 11b and the first folded side 11d. Further, the length n of the second bent side 12b is the same as that of the first folded side 11d.
It is set to be larger than the facing distance p between the tip of the first bent side 11 and the first rising side 11, but smaller than the length r of the first bent side 11b.

In an embodiment of the invention constructed as described above, a plurality of slats 1 are used to form a door panel.
When stitching the slats 1 in a row, with the adjacent slats 1 disposed at substantially right angles, the second hook-shaped portion 12c of one slat 1 is connected to the tip of the first folded side 11d of the other slat 1. The slat 1 is fitted between the facing sides of the rising side 11, and from this fitted state, one of the slats 1
By relatively rotating the adjacent slats 1 so that the corner portions of the second rising side 12 and the second bent side 12b of the slats 1 are abutted and supported by the first rising side 11 of the other slat 1, one The second hook-shaped portion 12c of one slat 1 is forcibly fitted to the first hook-shaped portion 11c of the other slat 1, and the face plate portions 10 of adjacent slats 1 are interlocked so that they are substantially flush with each other. become.

In this way, in the present invention, the adjacent slat 1
The two hook-shaped parts 11c and 12c are connected in a series by simply interlocking them, and unnecessary work such as temporary fixing and welding can be completely omitted, making it extremely easy to form a door panel. However, in this case, both the hook-shaped parts 11c and 12c, which are bent on the indoor side, are forcibly fitted to form an interlock connection. Therefore, the outdoor side surface of the face plate portion 10 does not participate in forced fitting. As a result, it is possible to reliably avoid the problems that occur when the slats and outdoor corner surfaces are forced to rub against each other, causing paint peeling, which occurs when the slats and outdoor corner surfaces are forced to fit together, which is the case with conventional interlock connections. As a result, the door panel will have no paint peeling on the outdoor side of slat 1.
There is no need for post-treatment such as painting, and rust can be suppressed in the assembled state, and the appearance can be improved.

[Operations and Effects] In summary, the present invention is constructed as described above, and although a door panel is formed by connecting a plurality of slats in a series by interlocking, the difference between adjacent slats is The connection is made by placing the second hook-shaped part formed by the second folded side and the second folded side so that the tip of the first folded side and the first rising side face each other with these parts arranged at approximately right angles. and from this fitted state, the corner portions of the second rising side and the second bent side are abutted and supported by the first rising side, and the adjacent slats are rotated relative to each other, The second hook-shaped portion is
The first hook-shaped portion formed by the first bent side and the first folded side is forcibly fitted to form an interlock connection such that the face plate portions of adjacent slats are substantially flush with each other.

As a result, adjacent slats are connected in a series by interlocking the hook-shaped parts bent on the indoor side, similar to the conventional interlocking connection. This will surely avoid problems such as the outdoor corner surfaces of the slats being forcibly rubbed and peeling of the paint film when they are forcibly fitted together. As a result, there is no need for post-treatment such as painting, and rust can be suppressed while the assembly is in place.
The appearance can also be improved.
