Description

Description: TECHNICAL FIELD The present invention relates to a shutter provided in an opening of a building, for example, an entrance, a window, a show window, etc., and particularly to a shutter using a panel member. .

(Prior Art) Conventionally, various things such as glass doors and shutters have been used for entrances, windows, show windows and the like of buildings. Although a shutter using a slat is also used, it is difficult to perform ventilation and lighting in a closed state.

Recently, a shutter that opens and closes by using a plurality of panel bodies and raising and lowering the panel body has appeared. Such a panel shutter can use not only a metal material but also various materials such as synthetic resin and glass as a material of the panel. In particular, those using glass are expected to be used in ordinary households and shops, and have effects not seen in conventional shutters using slats.

Furthermore, ventilation and lighting can be performed by rotating the panel surface. However, since the rotation of the panel surface tilts the panel surface by taking advantage of the fact that a once-closed shutter is lifted slightly to create a space between the panels, it is unstable in that state, and the movement of the panel is unstable. Since the panel member tilts inward and is unstable, and the panel is tiltable, it can be tilted by hand even during closing, which has a problem in terms of locking.

(Problems to be Solved by the Invention) The present invention has been made in order to solve the above-mentioned problems, and it is possible to change the angle of the panel member in a completely closed state, and perform ventilation and lighting. It is another object of the present invention to provide a panel shutter capable of stabilizing a panel member during ascent and descent and performing locking in a closed state.

(Means for Solving the Problems) The present invention relates to a panel shutter having an out frame that is guided by a guide rail and moves up and down, and a panel member rotatably supported by the out frame. An engaging portion for locking the rotation of the panel member is provided between the frame and the frame, and the locking of the engaging portion is released before the rotation of the panel member. is there.

(Embodiment) FIGS. 1 to 9 are diagrams for explaining a case where one embodiment of the panel shutter of the present invention is applied to a window of a building. FIG. 2 is a cross-sectional view of an end portion, FIG. 3 is a perspective view of a panel main body, FIG. 4 is a perspective view of a lowermost panel main body, FIG. 5 is an explanatory view of a driving member, and FIG. (A) is a side view of a connecting portion of a connecting chain, FIG. 6 (B) is a top view thereof, FIG. 7 is a cross-sectional view of a lower frame of a panel member, and FIG. 8 is an intermediate portion of a panel shutter. 9 is a cross-sectional view, and FIG. 9 is a cross-sectional view.

First, a general description of the panel shutter will be described.

As shown in FIGS. 8 and 9, for example, five panel bodies 1A, 1B, 1C, 1D, and 1E (in FIG. 9, reference numerals are denoted by 1) are respectively supported by support rollers 2. Which is attached to the connecting chain 3 and is guided by guide rails 4 attached to both sides of the window to move up and down an opening which is a window of the building. Is stored in. In this embodiment, since the storage portion 8 is outside the building (right side in FIG. 8), it can also serve as an eave. 29 is a screen door.

To release the shutter composed of the plurality of panel bodies 1A, 1B, 1C, 1D, 1E, the drive sprocket 5 is rotated forward to pull up the connecting chain 3, and the support rollers 2 attached to the panel body are sequentially stored. The panel body 1E, 1D, 1C, 1B, 1A is placed on the section guide rail 6 and stored while being moved on the storage section guide rail 6 in this order. The drive sprocket 5 is driven by a transmission chain 10, 11 from an electric motor 9.

To close the shutter, the driving sprocket 5 is reversed, the connecting chain 3 is pulled out, the panel main body is deployed along the guide rail 4, and the window is closed. In a state where the lowermost panel body 1A is not in contact with the lower window frame 7,
The connection chain 3 is stretched without slack, and a slight space is left between the panel bodies. Further, the driving sprocket 5 is reversed, and the respective panel bodies come into contact with each other to be completely closed. In this state, the chain from the last panel body 1E to the first sprocket 12 is stretched slightly. Behind the first sprocket 12,
Chain 14 is connected. Therefore, when the drive sprocket 5 is further reversed from the completely closed state, the chain 14 is pulled, and the chain 14 extending into the guide rail 4 is pulled up via the second sprocket 13, and the drive member 15 fixed to the end thereof is pulled. Is moved upward. As described later, the movement of the driving member 15 in the completely closed state causes
The tilting operation of the panel surface can be performed. Drive member 15
A spring 28 (FIG. 5), which will be described later, is attached to the, and the chain 14 is constantly pulled downward.

Since the load on the chain 14 is smaller than that of the connecting chain 3, for example, # 35 can be used for the connecting chain 3 and # 25 can be used for the chain 14. As shown in FIG. 6, the connection between the two chains is the first sprocket.
In the vicinity of 12, the rear end of the connecting chain 3 and the chain 14
This is done by inserting a pin 16 between the front end of the pin. The pins 16 protrude longer than the width of both chains, and are positioned so as to engage with a frame 6b provided above the support member 6a of the storage rail 6. As described above, the chain 14 is under tension by the spring 28 (FIG. 5),
Abuts on the frame 6b, thereby serving as a stopper for preventing the movement of the connecting portion when the connecting chain 3 is loosened. Therefore, the driving sprocket 5
However, the chain 14 does not move from the completely closed state until the reversing operation is further performed.

 The details of the panel body of the embodiment will be described.

FIG. 3 is a perspective view showing the vicinity of one end of the panel main body, and includes a panel portion 17 and out frames 18 arranged on both sides thereof. The panel unit 17 is a glass plate 17a
And a vertical frame 17b, an upper frame 17c, and a lower frame 17d. For the panel surface, not only a glass plate but also a suitable material such as a light alloy plate such as aluminum or an iron plate can be selected. As is clear from FIG. 2 of a cross-sectional view passing through the shaft 2a of the support roller 2, the vertical frame 17b of the panel portion is moved relative to the out frame 18 by the shaft 2b coaxially connected to the shaft 2a at the connecting portion 2c. It is supported rotatably. However, the shafts 2a and 2b do not have to be coaxial. It may be a separate axis. The out frame 18 is provided with a vertical hole that penetrates the rectangular hollow moving member 19.
Are slidably inserted. The length of the moving member 19 is equal to the length of the out frame 18. It is desirable that the end portion has a shape such as a spherical shape so that it can easily move in contact with the moving members of the panel body located above and below. Notch 18 provided below the out frame
a is not necessarily required because a is provided for the same reason. The moving member 19 only needs to be supported movably with respect to the out frame 18.

When the panel bodies 1 are stacked in the completely closed state, the out frames 18 come into contact with each other and receive the load of the upper panel body. The height of the panel portion 17 is slightly lower than the height of the out frame so as not to receive the load of the upper panel, so that the panel portion 17 can rotate in a completely closed state. Of course, a consensus structure may be adopted so that no inward or outward gap is opened between the panels.

FIG. 1 is a view for explaining a relational structure between a panel section and an out frame. The outer frame 18 shows a surface on the panel portion side, and the outer periphery of the vertical frame 17b of the panel portion is shown by a chain line. A lock claw 20 and an engaging pin 21 are fixed to a surface of the moving member 19 on the panel portion side through a cutout groove 18b of the out frame 18. Lock claw 20 is vertical frame 17b
And locks the panel portion to the out frame. The engagement pin 21 is engaged with the engagement hole 23a of the arm 23. But,
Since the engaging hole 23a is formed as a vertically long hole, the engaging pin 21 is
Does not engage with play. Arm 23, vertical frame 17b
Is rotatably supported by a shaft 23b fixed to the shaft 23b.

When the moving member 19 moves upward, first, the lock claw 20
The lock pin 22 is disengaged from the lock claw by the upward movement, and the engagement pin 21 pushes up the engagement hole of the arm 23 to rotate the vertical frame 17b to the position shown by the two-dot chain line. That is, when the moving member 19 is moved upward in the completely closed position, the panel member is unlocked. Therefore,
Until the moving member 19 moves upward, the rotation of the panel portion 17 is locked, so that it does not rotate when the panel main body is stored in the storage portion or during elevating. In addition, even when the panel member is closed, the panel member is prevented from rotating and is locked until the lock is released. After the lock is released, when the moving member 19 further moves upward, the panel member rotates to the inclined position. By the movement of the lower moving member, the moving member of the upper panel body also moves at the same time against the lower moving member, so that all the panel surfaces are similarly inclined. Depending on the amount of movement of the moving member,
The inclination angle can be controlled. The movement of the moving member is performed by moving the moving member of the lowermost panel body.

FIG. 4 is a perspective view showing the vicinity of one end of the lowermost panel main body, and a panel portion 17 is the same as FIG.
The relationship between the out frame 24 and the panel section 17 is the same as that described with reference to FIGS. The moving member 25 of the out frame 24 is the driving member 15 (FIGS. 5 and 8).
Is different from the above-mentioned out-frame 18 in that it can be moved. An engagement pin 25a that protrudes outward through the notch 24a of the out frame 24 is fixed to the moving member 25. A lock pin 26 is fixed to the outside of the out frame 24. A curved ball-shaped hook member 27 attached to the guide rail side is arranged to be engageable with the lock pin 26.

The drive member 15 shown in FIG. 5 is opposed to the out frame 24. FIG. 5A is a front view, in which the surface shown faces the outer surface of the out frame 24. In this embodiment, the lower end surface of the drive member 15 and the lower end surface of the out frame 24 coincide. The above-mentioned chain 14 is attached to the upper end of the driving member 15, and between the upper end and the lower window frame,
A spring 28 is provided to urge the drive member 15 downward. As is clear from FIG. 5B which is a perspective view seen from the out frame side, the shape of the driving member 25 is a cam portion.
15a and a projection 15b are provided. The cam portion 15a engages with the hook member 27, and the protrusion 15b engages with the engagement pin 25a.

When the shutter is completely closed, as shown in FIG. 5 (A), the cam portion 15a does not engage with the hook member 27, and
5b is a position that does not engage with the engagement pin 25a. Chain 1
When 4 is pulled by the reverse rotation of the driving sprocket,
The cam portion 15a engages with the hook member 27, rotates the hook member 27, engages with the lock pin 26, and prevents the out frame 24 from rising. In this state, the shutter can be locked. In this state, since the panel member is locked to the out frame, the locking is complete.

To tilt the panel, the drive sprocket 5
Reverse it further. The driving member 15 further rises, and the protrusion
15b engages the engagement pin 25a and raises it. The raising of the engaging pin 25a raises the moving member 25 to which it is fixed, and unlocks the panel portion from the out frame as described with reference to FIGS. Done.

Note that the lock mechanism between the out frame and the panel member and the lock release mechanism are merely examples, and are not limited to the above-described embodiments.

(Effects) As described above, according to the present invention, in the panel shutter in which the panel surface can be inclined in the closed state and a gap can be opened between the panels, the engaging portion is released after the shutter is closed. Otherwise, since the panel member does not rotate, there is an effect that the panel member does not become unstable during ascent and descent, and that the locking is complete.
