Description

Description: TECHNICAL FIELD The present invention relates to a shutter provided in an opening of a building or a shroud window, and particularly to a shutter using a panel.

(Prior art) Conventionally, a thin steel plate or a light alloy plate called a slat has been used as a plate-like body that is a main component of a shutter provided at an entrance of a building or the like. Recently, shutters using panels instead of slats have also appeared. Such a panel shutter is not limited to a metal material, and various materials such as synthetic resin and glass can be used as the material of the panel. A variety of uses are being considered, such as providing lighting means for the vehicle. When glass is used for the panel surface, since the inside can be seen through, in a shop or the like, it is possible to show the display inside the store after the shutter is closed. Was.

The panel shutter described in Japanese Utility Model Laid-Open No. 60-172988 can perform ventilation and lighting by rotating a panel member, so it is difficult to perform ventilation and lighting in the closed state of the shutter. Excellent compared to slat shutters.

However, when the panel is raised and lowered, the panel member moves while rotating and tilting, so that there is a problem that the shutter cannot be opened and closed smoothly.

(Problems to be Solved by the Invention) The present invention has been made in order to solve the above-described problems, and a panel shutter in which a panel member is rotatably coupled to an out frame. It is an object of the present invention to provide a panel shutter capable of ensuring a positional relationship between the two by enabling engagement with a member.

(Means for Solving the Problems) The present invention relates to a panel shutter, comprising: a plurality of out frames; a panel member rotatably coupled to the out frames; and a support shaft provided near an upper portion of the out frames. And a panel shutter having a connecting member for connecting the support shaft at a predetermined pitch, wherein a fitting portion is provided in which the out frame and the panel member can be engaged with a surface on the rotation side of the panel member. It is characterized by having.

(Embodiment) FIG. 1 is an explanatory view of an open / close state of an embodiment of a panel shutter according to the present invention. FIG. Perspective view, FIG.
FIG. 4 is a perspective view for explaining an engaging portion and an engaging pin.
Although FIG. 1 shows only the upper panel, the same applies to other panels. In the drawing, 1A is a panel member, 2A is a panel surface, 3A is a front member of a side frame, 4A is a rear member of a side frame, 5A is a side member of a side frame, 6A is an out frame, 7A is a panel hanging shaft, and 8A is Support roller, 9A is a sliding member, 10A is a link member, 11A is a coupling shaft between one end of the link member 10A and a side member 5A of the side frame, 12A is an engagement portion with the long hole 13A of the other end of the link member 10A. , 13A are long holes, 14A is a locking portion, 15A is a locking pin, 16A is a ridge, and 17A is a concave groove.

As the panel surface 2A of the panel member 1A, for example, a glass plate can be used. In this embodiment, the side frame includes a front member 3A, a rear member 4A, and a side member 5A, and fixes a panel surface and holds a panel suspension shaft 7A. The panel suspension shaft 7A is attached to a sliding member 9A, and the sliding member 9A is vertically slidably fitted into a vertical hole provided in the out frame 6A. The vertical hole is provided so as to penetrate to the lower portion of the out frame, and can receive the sliding member of the lower panel.

Attachment of the panel suspension shaft 7A is rotatably supported on at least one of the sliding member 9A and the side member 5A, thereby supporting the panel member 1A rotatably with respect to the out frame 6A. I have. A support roller 8A is attached to the panel suspension shaft 7A, and the support roller 8A rolls on a storage rail in a storage section (not shown) to store each panel. The lifting and lowering of each panel when the shutter is opened and closed is performed by a connecting chain rotatably connected to the panel suspension shaft 7A, and this mode will be described with reference to FIG.

The link member 10A is rotatably supported at one end 11A by the side member 5A of the panel member 1A, and the engagement portion 12A at the other end is slidably engaged with a long hole 13A provided in the out frame 6A. doing. Further, when the panel is suspended by the panel suspension shaft 7A, a spring member (not shown) is provided with a sliding member 9A so that the out frame 6A does not lower, that is, the outer frame 6A is raised with respect to the panel member 1A. And the outer frame 6A. Therefore, when the panel is suspended, the locking portion 14A is locked by the locking pin 15A, and the panel member 1A does not rotate.

As described above, since the panel member 1A is suspended above the panel suspension shaft 7A and the panel suspension shaft 7A is suspended outside the out frame 6A by the connecting chain (not shown), the panel suspension shaft If the flexure occurs in 7A or if there is play between panel suspension shaft 7A and out frame 6A, the positional relationship between out frame 6A and panel member 1A cannot be maintained normally. For example, when the panel suspension shaft 7A has a bend, the shapes of the out frame 6A and the panel member 1A expand at the lower portion, and open like a ア ウ ト, or the out frame 6A fluctuates. .

This phenomenon is unavoidable not only in the embodiment of FIG. 1 but in the case of a structure in which the panel member is supported by the out frame and suspended above.

To cope with this, in the present invention, a fitting portion engageable between the out frame and the panel member is provided.

Returning to the embodiment shown in FIG. In this example,
The fitting portion is constituted by a ridge 16A formed over the entire length at the end of the front member 3A of the side frame, and a concave groove 17A formed over the entire length at the end of the out frame 6A.

When the panel member 1A is not rotated, the ridge 16A and the concave groove 17A are engaged, and therefore, the above-described phenomenon does not occur. Further, in this embodiment, since the out frame and the panel member move relatively vertically, the fitting portion is formed to be slidable up and down. However, the present invention is not limited to this. A fitting portion may be formed on a part of the panel member. In that case, it is good to form as low as possible.

FIG. 1 shows the out frame and the panel member of the panel separated from each other for explanation. Also, the sliding member 9A is at the lowered position, and the panel moves up and down in this state. In this state, when the out frame 6A is fixed and the panel suspension shaft 7A is moved upward against a spring (not shown), the panel member 1A is moved upward with respect to the out frame 6A. With the movement, the locking between the locking portion 14A and the locking pin 15A is released, and the engaging portion 12A of the link member 10A moves upward in the elongated hole 13A and eventually hits the top of the elongated hole 13A. . Further, when the panel suspension shaft 7A continues to move upward, the coupling shaft 11A of the link member 10A is pulled up, so that the panel member 1A rotates about the engagement portion 12A as a rotation axis.

FIG. 2 is an explanatory diagram of the entire open / closed state of the panel shutter described in FIG. In the figure, the same parts as those in FIG. Reference numeral 18 denotes a drive sprocket, 19 denotes a storage rail, 20 denotes a lock member, and 21 denotes a connecting chain.

FIG. 2 (A) shows a state during the downward movement. By rotating the driving sprocket 18 counterclockwise, the connecting chain 21 is driven, and each panel is pulled out one by one from the storage rail 19 and descends. In the lowering state, each panel is lowered with a gap between the upper and lower sides. In this state, since the fitting portion described in FIG. 1 is in the engaged state, the out frame and the panel member are integrated,
The phenomenon that the vertical line becomes a letter "C" and the out frame fluctuates does not occur.

FIG. 2 (B) shows a state where all the panels have been lowered. When the descent is completed, the out frame 6A at the upper end is locked by the lock member 20. Out frame 6A
May be provided with an engagement portion with the lock member 20.

To release the panel shutter, the lock by the lock member 20 is released, the drive sprocket 18 is rotated in the opposite direction, and the connecting chain is pulled up.

When the driving sprocket 18 is slightly rotated clockwise while the outer frame 6A at the upper end is locked by the lock member in the closed state of the panel shutter, the loosened connecting chain is tensioned, and the connecting chain 21 is further pulled up slightly. The sliding member is lifted up against the spring member which does not work, and as shown in FIG.
The other ends of 10A, 10B,... Slide up in slots 13A, 13B,. During this movement, the sliding member of the lower panel enters the sliding hole of the outer frame of the upper panel. However, since the fitting portion between the outer frame and the panel member is in the engaged state, the position of the outer frame is changed. It is ensured that the sliding member of the lower panel enters the sliding hole of the out frame of the upper panel in a fixed position. The above-mentioned gap is added to the amount of movement of each panel as the panel is positioned higher. Therefore, the length of the long hole is correspondingly longer toward the upper out frame.

When the connecting chain 21 is further pulled up, the state shifts to the state shown in FIG. 2D, and the other ends of the link members 10A, 10B,. As it was
The sliding members 9A, 9B,... Rise, and the link members 10A, 10B,.
.. Can rotate to tilt the panel members 1A, 1B,.

In order to restore the inclination of each panel member, the drive sprocket 18 may be driven to rotate in the reverse direction.

(Effects of the Invention) As is clear from the above description, according to the present invention, in the panel shutter in which the panel member rotates with respect to the out frame, the positional relationship between the out frame and the panel member is ensured. In addition, there is an effect that a panel shutter with which the out frame does not fluctuate can be provided.
