Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a panel unit fitting device for a panel shutter that allows panel units of a panel shutter to be fitted to each other even if the panel units of the panel shutter are warped.

[Conventional technology]

In a panel shutter, each panel unit that makes up the shutter surface is supported by guide rails on both sides when the shutter is closed, and the fitting portions formed over the entire width of the top and bottom sides of each unit fit together and form a flat surface. When the shutter is opened, the panel units are stacked in the thickness direction and housed in the shutter case above the guide rail to open the opening.

Conventionally, one of the upper and lower sides of the fitting portion of the panel unit is formed as a groove with a uniform cross section, and the other side is formed as a convex strip with a uniform cross section that fits in the groove.

[Problem that the invention attempts to solve]

However, in the conventional fitting section, when a part of the panel unit warps, the center of the lower edge of the fitting section of this panel unit rides on the upper edge of the fitting section of the normal lower panel unit. There was a problem that the two fitting parts could not be fitted, and the shutter would not be completely closed.

The present invention was devised to solve the above-mentioned conventional problems, and its purpose is to ensure that even if a portion of the panel unit of the panel shutter is warped, the mating portions of the panel shutter will not be damaged when the shutter is closed. An object of the present invention is to provide a panel unit fitting device for a panel shutter, which allows the shutters to be completely closed when the shutters are fitted together.

[Means for solving problems]

In order to achieve the above object, in the present invention, fitting portions are formed on the upper and lower sides of the panel unit, and when the panel shutter is closed, the fitting portions of each panel unit fit into each other to form one plane. In a panel unit of a panel shutter, one of the fitting parts on the upper and lower sides of the panel unit is a groove with a substantially trapezoidal uniform cross section along that side, and the other fitting part is fitted into the groove fitting part. A convex strip with a substantially trapezoidal cross section that can be combined,
The height of the protruding strip is continuously reduced from both ends toward the center.

[Effect]

Therefore, in the panel unit fitting device for a panel shutter of the present invention, when the panel shutter is closed, the panel units stored in the shutter case above the guide rail are sequentially pulled out and guided. They are guided by the rails and descend while being arranged in a flat plane, and even if some of the panel units are warped at this time, both ends of the panel units are regulated by the guide rails, so the concavities on the lower side will be avoided. Both ends of the groove fitting part can first be fitted to both ends of the protrusion fitting part on the upper side of the lower normal panel unit. As the weight of the upper panel unit is added to the lower panel unit, the convex groove fitting portion of the lower panel unit moves from both ends toward the center with respect to the groove fitting portion of the upper panel unit. They gradually fit together like driving a wedge. As this fitting progresses, the warpage of the upper panel unit is corrected, and the two fitting parts finally fit together properly, allowing the panel shutter to be completely closed.

〔Example〕

The present invention will be explained in detail below based on an illustrated embodiment.

FIG. 1 is a perspective view of a panel unit according to an embodiment of the present invention, FIG. 2 is a side view, and FIG. 3 is a front view of a panel shutter to which the present invention is applied, showing the closed state.

As shown in FIG. 1, the panel unit 1 is formed of a metal plate into a horizontally long rectangular shape, and has a groove fitting part 2 along its lower side and a protruding fitting part 3 along its upper side.

The groove fitting part 2 on the lower side is formed of a groove having a substantially trapezoidal shape with a uniform cross section, and the convex groove fitting part 3 on the upper side has a substantially trapezoidal shape that can be fitted into the groove fitting part 2 on the lower side. It consists of a convex strip with a cross section. The height H of this convex fitting part 3 is the same as the groove depth H of the concave groove fitting part 2 at both ends of the panel unit 1, but the height increases from both ends toward the center. It is continuously subtracted and becomes h (<H) in the central part. The convex fitting portion 3 of the illustrated embodiment is connected to the panel unit 1 as shown in FIG.
A concave-shaped convex strip with a substantially trapezoidal cross section and a long groove 3a formed in the length direction is made separately from the panel unit 1 by a plurality of screws 4 inserted into the long groove 3a.
is fixed to. The groove fitting portions 2 may be formed on the upper side of each panel unit 1, and the protruding groove fitting portions 3 may be formed on the lower side of each panel unit 1 except for the bottom panel unit.

In the embodiment device having the above configuration, as shown in FIG. 3, when the panel shutter 10 is closed, the panel units 1 stored in the shutter case 12 above the guide rails 11, 11 in a stacked manner in the thickness direction are sequentially pulled out. The panel units are guided by the guide rails 11, 11 and descend while being arranged in a plane. At this time, even if some of the panel units are warped, both ends of the panel units are regulated by the guide rails. Therefore, both ends of the groove fitting part 2 on the lower side can first be fitted to both ends of the convex fitting part 3 on the upper side of the lower normal panel unit. As the weight of the upper panel unit is added to the lower panel unit, the convex groove fitting portion 3 of the lower panel unit becomes higher at both ends with respect to the groove fitting portion 2 of the upper panel unit. The two parts gradually fit together as if driving a wedge from the center part to the lower central part. As this fitting progresses, the warpage of the upper panel unit is corrected, and both fitting parts 2 and 3 are finally fitted properly, and the panel shutter 10 can be completely closed.

[Effect of idea]

As described in detail above, according to the device of the present invention, one of the fitting devices formed on the upper and lower sides of the panel unit of the panel shutter is a concave groove with a substantially trapezoidal uniform cross section along that side, and the other is a concave groove having a substantially trapezoidal uniform cross section. Since the protruding strip has a substantially trapezoidal cross section that can fit into the groove, and the height of the protruding strip decreases continuously from both ends toward the center, some panel units may warp. Also, when closing the panel shutter, one fitting part of the warped panel unit is connected to the other fitting part of the lower normal panel unit from both high ends of the protruding fitting part. The two mating parts are fitted together by driving a wedge into the lower center part, the warpage of the upper panel unit is corrected, and both mating parts are finally fitted properly, and the panel shutter is This has the practical effect of being completely closed.
