Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a slat structure for a panel shutter that is attached to an opening such as a doorway of a building.

[Problems to be solved by the prior art and the invention] In general, this type of panel shutter has the following problems:
Some panels are used in panel shutters by fitting panel plates such as glass plates or synthetic resin plates into grooves between upper and lower horizontal frames that extend in the left-right direction. However, this one, for example,
As shown in Japanese Patent Application Laid-Open No. 166154 and JP-A-59-72385, in order to reduce the diameter of the winding on the winding drum,
The horizontal frame protrudes from the surface of the panel board, and as a result, when the shutter curtain moves up and down, the horizontal frame comes into contact with the guide rail, causing an unpleasant noise.

Therefore, it is proposed to provide a protective material on the surface of the horizontal frame, but in addition, the slats for conventional panel shutters simply fit the upper and lower edges of the panel plate into the panel plate fitting grooves formed on the upper and lower edges of the horizontal frame. Since the panel board is only configured to be able to be fitted from any direction, there is a problem in that the panel plate easily comes out of the fitting groove and cannot be handled independently as a slat in this state. Therefore, as shown in Figure 5,
A vertical frame 10 is assembled between the upper and lower horizontal frames 6 and 7 at a predetermined pitch, and by integrally forming a frame with the vertical frame 10, the slat is assembled in a state in which the panel board is prevented from coming off.

However, if this is done, there is a problem that the daylight area becomes narrow due to the presence of the vertical frame. On the other hand, it has been proposed to widen the vertical frame pitch to increase the lighting area, but if the vertical frame pitch is widened, the purpose of providing the vertical frame will be diminished, and in areas far from the vertical frame, There was a problem that the fitting support by the horizontal frame of the panel board became unstable.
There is also a limit to increasing the vertical frame pitch.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a slat structure for a panel shutter that can eliminate these drawbacks. The slats constituting the shutter curtain of the shutter are constructed by using upper and lower horizontal frames having connecting parts for interlocking the slats so that they can swing freely with each other, and a panel plate interposed between the upper and lower horizontal frames. In the panel shutter, an engagement groove is formed at least on the surface side of the upper and lower horizontal frames, and a protective member made of a rubber elastic body is provided in the engagement groove so as to protrude from the surface of the horizontal frame. At the same time, the engaging ribs are slidably fitted in the left and right direction to prevent them from coming out in the thickness direction, and the upper and lower edges of the panel plate have locking ribs that protrude in the thickness direction, and the upper edge of the horizontal frame Alternatively, the panel plate fitting groove formed on the lower edge has a slide that is further concave in the thickness direction in order to install the panel plate in a state where the locking rib is slid in the left and right direction and prevented from coming out in the vertical direction. It is characterized in that a fitting groove is formed.

With this configuration, the present invention can prevent the slats from rubbing against each other in a slat constructed by providing a horizontal frame that projects from the panel body, and also eliminates the need for a vertical frame and incorporates the slat. It has been made possible to do so.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter curtain constituting a panel shutter installed in the opening of a building, and the shutter curtain 1 is designed to rotate forward and backward of a winding drum 3 housed in a shutter case 2. The opening and closing are performed by moving up and down while being guided by the guide rail 4, as in the conventional art.

Reference numeral 5 denotes a slat constituting the shutter curtain 1, and the slat 5 has upper and lower horizontal frames 6 and 7 formed with connecting portions 6a and 7a, respectively, which are connected to each other in a swingable interlocking manner. It is composed of a panel plate 8 interposed between the horizontal frames 6 and 7, and the connecting portion 6a of the horizontal frames 6 and 7,
A panel plate fitting groove 6 into which the upper and lower edges of the panel plate 8 fit is provided on the upper and lower edges on the opposite side to the edge where the panel plate 7a is formed.
b, 7b are recessed, but these fitting grooves 6b, 7b
Further, slide fitting grooves 6d and 7d are formed which are further concave in the thickness direction.
On the other hand, locking ribs 8a are formed on the upper and lower edges of the panel board 8 to protrude in the thickness direction, respectively.
The panel plate 8 has the slide fitting groove 6d,
By slidingly fitting in the left-right direction into the panel plate fitting grooves 6b, 7b in which the panel plates 7d are formed, they are assembled into the horizontal frames 6, 7 while being prevented from coming out in the vertical direction. In this embodiment, the horizontal frames 6 and 7 are made of extruded aluminum, and the panel plate 8 is made of polycarbonate resin.

On the other hand, 9 is a protective material, and the protective material 9 is formed of a rubber elastic material. The protective member 9 is also formed with an engaging rib 9a, and the protective member 9 is slidably fitted in the left and right direction into the engaging grooves 6c and 7c integrally formed on the surfaces of the horizontal frames 6 and 7. The attached protective member 9 is provided with protruding portions 9b that protrude from both the front and rear surfaces of the horizontal frames 6, 7, respectively. Here, in the first embodiment (see FIG. 2), the protruding width of the protective member 9 is of a stripe type, in which the width of the protruding groove substantially matches the groove width of the engaging grooves 6c and 7c. On the other hand, in the second embodiment (see FIG. 3), the protective material 9 protrudes to cover the entire frame surfaces of the horizontal frames 6 and 7. Further, that of the third embodiment (see Fig. 4)
In this example, an uneven cut line is formed on the surface of the protective material protrusion 9b.

In the embodiment of the present invention constructed as described above, the opening is opened and closed by the up and down movement of the shutter curtain 1 as the winding drum 3 rotates forward and backward, as in the conventional case. When the shutter curtain 1 is moved up and down, the present invention reliably prevents the generation of unpleasant noises.

That is, in the present invention, although the horizontal frames 6 and 7 constituting the slat 5 protrude more than the panel plate 8 in the thickness direction, the frame surfaces of the horizontal frames 6 and 7 that protrude more than the panel plate 8 A protective member 9 is integrally attached so as to protrude even further than the protective member 9. Therefore, this protective material 9 protects the guide rail 4 and the horizontal frame 6,
7, and when winding onto the winding drum 3,
Not only the horizontal frames 6 and 7, but also the horizontal frames 6 and 7 and the panel board 8
This effectively prevents direct contact with For this reason, the shutter curtain 1 is able to move up and down quietly and smoothly, with the generation of unpleasant noises caused by metal-on-metal contact being significantly reduced. It is possible to effectively prevent the board 8 from being damaged and maintain its quality over a long period of time, and the protective material 9 forms a striped pattern parallel to the horizontal frames 6 and 7. Therefore, it can be made into something extremely superior in terms of design.

Moreover, in this case, the panel plate 8 is assembled into the horizontal frames 6 and 7 in such a manner that it is prevented from being removed in the vertical direction. That is, the locking ribs 8a protruding in the thickness direction from the upper and lower edges of the panel plate 8 are connected to the panel plate fitting grooves 6.
Slide fitting groove 6 recessed in the thickness direction in b, 7b
By slidingly fitting into the horizontal frames d and 7d, the panel plate 8 is integrally assembled with the horizontal frames 6 and 7 in a vertically fixed manner. As a result, in the slat 5, the panel body 8 itself is incorporated as a member for connecting the upper and lower horizontal frames 6 and 7, and the vertical frame for connecting the upper and lower horizontal frames 6 and 7 as in the past is no longer necessary. Therefore, not only can the number of parts be reduced reliably, but also the panel body 8 can be made wider over the entire width of the opening, and the lighting area becomes wider.

Furthermore, the slat 5 can be easily assembled by sliding the protective material 9 and the panel plate 8 in the left and right directions with respect to the horizontal frames 6 and 7, which simplifies the slat assembly work at the factory. It doesn't have to be particularly complicated.

In addition, as in the second embodiment, the protective material 9 is attached to the horizontal frames 6 and 7.
When the entire width of the surface of the frame is covered, the entire surface of the frame can be protected, and the strength of the protective material 9 itself is improved, which has the advantage that the protective material 9 can have a long life. Furthermore, in the case of the third embodiment in which uneven cut strips 9a are formed, not only the design is variable, but also the contact area between the protective materials 9 when wound on the winding drum 3 is increased. As it becomes smaller, the protective material 9 itself can also be protected.

It should be noted that the present invention is of course not limited to the above embodiments, but the protective material may be provided only on either one of the upper and lower horizontal frames, for example.

[Operations and Effects] In summary, the present invention is constructed as described above, and the horizontal frame is protected by the protective material provided so as to protrude from the surface of the horizontal frame that projects in the thickness direction from the panel board. Direct contact with the guide rail or
It is possible to reliably prevent the horizontal frames from coming into contact with each other, and therefore it is possible to effectively prevent the generation of unpleasant noises due to metal contact, and also to prevent the horizontal frames from being damaged. It can be prevented.

Moreover, when assembling the panel board into the horizontal frame, the locking ribs provided on the panel board that protrude in the thickness direction,
This is achieved by sliding in the horizontal direction into a slide fitting groove that is concave in the thickness direction provided in the panel plate fitting groove, and as a result, the panel plate is prevented from coming out in the vertical direction with respect to the horizontal frame. As a result, the slats are assembled in such a way that the daylighting panel body itself doubles as a member for connecting the upper and lower horizontal frames, and the slats are integrated with the upper and lower horizontal frames as before. This eliminates the need for a vertical frame to connect the
Not only can the number of parts be reduced reliably, but also the panel body can be made wider over the entire width of the opening, which increases the daylighting area.
