Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a manual opening / closing device for a skylight attached to a roof or the like of a building.

[Problems to be Solved by Prior Art and Invention] Generally, the manual opening and closing device for this type of skylight is roughly classified into a push-pull chain type and a gas damper type. The former is to bend freely in the stored state and to open the skylight by pushing up the window body with a push-pull chain that is regulated to bend in the extended state, but the push-pull chain cannot be extended and retracted. Since it is performed by rotating the opening / closing handle, there is a disadvantage that opening and closing takes time. On the other hand, in the latter, the skylight is opened by the energy stored in the gas damper at the time of closing, so it can be opened only by releasing the locking device that locks the skylight in the closed state. (If the installation position of is low, do it by hand directly) to the open window body,
The skylight can be closed by pulling it. Therefore, compared to the push-pull chain type, it can be opened and closed in a shorter time.However, in this type, it is necessary to engage the hook bar with the window body in the open state at the time of closing operation. Perhaps there is a drawback that the hook rod is difficult to engage due to the high engagement position, but a large operating force is required to close the window body against the urging force of the damper, so operability is increased. Was a problem.
In addition, in the closing operation, the hook rod has to be inserted into the fixed frame to reach the window body engaging portion, so that the screen door cannot be attached to the fixed frame.

[Means for Solving the Problems] The present invention has been devised with the object of providing a manual opening / closing device for a skylight that can eliminate these drawbacks in view of the above-mentioned circumstances, and a building side A side of the movable frame is swingably attached to a fixed frame that is fixedly attached to, and a damper that urges the movable frame toward the open side and a lower moving frame that moves downward are provided between both frames. In a skylight provided with locking means for automatically locking in a closed position and unlocking by operating a unlocking tool, a string suspending portion for suspending an operation string is provided on the movable frame side. The fixed frame side has a winding drum that stores energy on the side for winding the operation cord, and a cord that locks a hook portion provided at the tip of the operation cord in a free state in the cord withdrawing direction. A locking portion is provided.

With this configuration, the present invention remarkably improves the operability in the opening and closing operation of the skylight and enables the installation of the screen door.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a skylight mounted on the roof of a building, the skylight 1 being a fixed frame 2 fixedly mounted on the roof side, and a movable hinged to the fixed frame 2 so as to be openable and closable. It comprises a frame 3, an outer glass 4 and an inner glass 5 fitted into the movable frame 3, and members such as a gas damper 6 interposed between the frames to urge the movable frame 3 toward the open side. All of the configurations are conventional.

Reference numeral 7 denotes a fixed side shaft which is rotatably supported by an inner peripheral surface of the fixed frame 2 (opposite side of the hinged part) via a bracket 7a. Has a pair of rock plates 8 facing upward and downward integrally fixed to each other. A lower end of the lock plate 8 is connected with an ammunition 9 for urging the upper end of the lock plate 8 toward the inside of the frame. Further, a locking groove 8a is formed on the upper end portion and opens toward the inside of the frame. That is, the lock plate 8
Holds the movable frame 3 in the closed state by locking the movable side shaft 10, which is provided on the movable frame 3 in parallel with the fixed side shaft 7 with the locking groove 8a, while being integrated with the fixed side shaft 7. By rotating the lock release angle 11 provided in the lower part from below, the locking of the movable side shaft 10 is released and the opening operation of the movable frame 3 by the gas damper 6 is allowed. . Furthermore, a convex portion 8b is formed on the lower side of the locking groove 8a, and the convex portion 8b is a movable shaft when the lock is released.
By forcibly pushing up 10, the initial operation of the gas damper 6 is assisted.

Further, 12 is a winding drum rotatably provided in an intermediate portion of the fixed-side shaft 7, and a belt 13 is wound around the winding drum 12. A spiral ammunition machine 12a, which stores energy by the rotation of the winding drum 12 associated with the drawing, is installed. On the other hand, the belt 13 has a base end locked to the winding drum 12, and the tip end side pulled out from the winding drum 12 has a roller portion 10 of the movable side shaft 10.
It is suspended by a, and the tip portion is hung from the movable side shaft 10 to be inserted into the locking portion 14 and is also locked to this. That is, an engaging fitting 13a is provided at the tip of the belt 13, and the engaging fitting 13a is locked to the engaging portion 14 so that further winding of the belt 13 is restricted. There is. The length of the belt 13 is set so that substantially the entire length is pulled out from the winding drum 12 in the open state. Further, 15 is a cover attached to the fixed frame 2 to cover the manual opening / closing device including the winding drum 12 and the like from below, and 16 is the fixed frame 2 excluding the mounting portion of the cover 15.
It is a screen door that covers the hollow part of.

In the embodiment of the present invention constructed as described, the skylight 1
As shown in FIGS. 5A and 5B, the lock release angle 11 is pushed upward by the hook rod to release the locking of the movable frame 3 by the lock plate 8 to open the lock release angle 11. Belt 13 at this time
Is pulled out from the winding drum 12 by the ascending movable shaft 10. On the other hand, the skylight 1 is closed by engaging a hook rod with an engaging metal fitting 13a located near the lock release angle 11 and pulling the hook rod downward. That is, by pulling the engaging metal fitting 13a downward, the movable frame 3 integrated with the fixed shaft 10 around which the belt 13 is suspended moves downward, and in the closed position, the fixed shaft 10 automatically moves to the lock plate 8. The skylight 1 is closed by being locked to the belt 1, and the belt 13 pulled out is wound around the winding drum 12.

As described above, according to the present invention, the gas damper 6 is configured to open the skylight 1.
The engaging metal fitting 13a for engaging the hook rod when closing the
The fixed frame 2 is not provided on the movable frame 3 side unlike the conventional case.
It is configured to be located on the side. Therefore, it is possible to facilitate the operation of the hook rod by setting the engagement position of the hook rod during the closing operation to a low position equivalent to that of the push-pull chain system.

Moreover, since the movable frame 3 is closed through the belt 13 suspended around the movable shaft 10, the operating force can be greatly reduced by the so-called pulley principle, and the operability during the closing operation can be significantly improved. .

Further, since it is not necessary to insert the hook rod into the fixed frame 2 to reach the movable frame 3 side at the time of the closing operation, the screen door can be attached to the fixed frame 2 side.

Further, in the present embodiment, the locking groove of the lock plate 8
Since the convex portion 8b is formed on 8a and the movable side shaft 10 is forcibly pushed up at the time of unlocking, the initial operation of the gas damper 6 is assisted. The movable frame 3 can be reliably opened even when a malfunction (due to biting of the packing) occurs.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and for example, as the operation cord, if it is long, a belt-shaped one or a wire-shaped one can be appropriately used. it can.

[Effects] In summary, since the present invention is constructed as described above, the movable frame is automatically opened by the damper based on the operation of the releasing tool of the locking means, while the lowered movable frame is Although it is configured to automatically lock in the closed position, the movable frame in the open state moves downward as the hook part locked on the fixed frame side is pulled out and locked. The means will automatically lock and close. Therefore,
The operation of closing the skylight can be performed by engaging the hook portion located on the fixed frame side, which is lower than that, without extending the hook rod or hand to the movable frame side as in the conventional case. As a result, the operability during the closing operation can be significantly improved.

Moreover, since the movable frame is closed via the operation string suspended by the string suspension portion, the operation force is greatly reduced by the so-called pulley principle, and the operability during the closing operation can be further improved.

Further, at the time of the closing operation, it is not necessary to insert the hook rod or the hand into the fixed frame to reach the movable frame side, so that the screen door can be attached to the fixed frame side.
