Description

[Detailed Description of the Invention] Industrial field of application The present invention is, like a skylight, a position where the shoji is aligned with the window frame while being held in a posture substantially parallel to the opening surface of the window frame and the side of the window frame. The present invention relates to a window opening / closing device that opens and closes by being moved to and from a position that is deviated.

Problems to be Solved by Conventional Techniques and Inventions For example, in a skylight installed on the roof of a building, the window frame should rise above the roof to prevent rainwater on the roof from flowing into the room. In addition, a downward eave is formed on the outer periphery of the shoji so as to cover the periphery of the window frame in order to prevent rain from entering through the gap between the window frame and the shoji when the window is closed. In such a skylight, opening and closing is performed by moving the shoji screen between a position aligned with the window frame and a position displaced laterally of the window frame while holding the shoji in a posture substantially parallel to the opening surface of the window frame. In this case, it is necessary to move the shoji so that the eaves do not interfere with the window frame. As a suitable opening / closing device for such a skylight, conventionally, two parallel frames of the window frame are each provided with two parallel windows. The base end of the link is swingably supported, and the swing end of each link is rotatably connected to the frame of the shoji to support the shoji in a horizontal posture parallel to the opening surface of the window frame. Immediately after opening the window and closing the window by swinging the shoji in a horizontal posture between the closed state where the window frame is closed and the opened state which is located on the side of the window frame. Immediately before this, move it almost vertically with respect to the window frame, so that the eaves do not interfere with the window frame. It is that to be able to. However, in this conventional opening / closing device, since the shoji is supported by the elongated link, the holding of the shoji is unstable in the fenestration state, and particularly, the link stands up and the position of the shoji is high. However, there is a drawback in that the shoji may be shaken by the wind to cause rattling.

Means for Solving the Problems As a means for solving the above problems, the present invention provides a window frame with an elongated toothed drive member such as a geared cable, a chain, a toothed belt, or a rack along the window frame. Movably arranged in a direction, and a slider formed by freely supporting only an internal threaded body circumscribing and engaging with the toothed drive member is mounted in a direction parallel to the toothed drive member.
A screw rod fixed to a sliding door, which is substantially parallel to the window frame, at a substantially right angle and non-rotatably is screwed into the female screw body, and is engaged with the slider so that the toothed drive member can move integrally in both directions of opening and closing. Then
In addition, the structure is such that the engagement with the toothed drive member is released only in the window-closed state in which the shoji is aligned with the window frame, and the connecting body that allows relative movement of the toothed drive member in both opening and closing directions is supported.

The operation and effect of the present invention With the above configuration, the toothed drive member is disengaged from the connecting member in the state where the shoji blocks the opening of the window frame, and the toothed drive member is moved relative to the slider in the window closing direction. Are moving,
When the toothed drive member is moved in the window opening direction from the closed window state, the internal threaded body rotates as the toothed drive member relatively moves without moving the slider,
The screw rod is advanced to separate the shoji from the window frame, and when the shoji and the window frame have a predetermined gap, the toothed drive member is engaged with the connecting body to be connected to the slider. Is because the toothed drive member and the slider move integrally while the rotation of the female screw body and the screw rod are stopped to advance,
The sliding doors move in parallel along the window frame while keeping a certain distance from the opening surface of the window frame to release the window, and also move the toothed drive member in the window closing direction from the open state. Then, the slider moves integrally with the toothed drive member without rotation of the female screw body and screwing of the screw rod due to the engagement of the toothed drive member and the coupling body, and the shoji screen is opened. When the shoji reaches a position that aligns with the window frame while moving in parallel with the window frame while maintaining a constant distance from the opening surface of the frame, engagement between the connecting body and the toothed drive member is achieved. Since the slider is released, after that, only the toothed drive member relatively moves while the slider remains stopped, whereby the female screw body rotates and the screw rod advances, thereby causing the shoji to approach the window frame. The window frame is closed by moving in parallel as shown in Fig. It is so arranged to support the window frame,
Unlike conventional devices that use links, the shoji screen can be held stably during window opening, and the shoji screen can be placed along the window frame while being slightly separated from the opening surface of the window frame. Since it can be moved in parallel, there is an effect that it is possible to prevent the shoji from being shaken by the wind and causing rattling.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a rectangular window frame fixedly installed on the roof of the building, which extends above the roof top a over the entire circumference to prevent rainwater accumulated on the roof from flowing down indoors. The window frame 1 is provided with a shoji 2 which is formed on the outer periphery of the window frame 1 by extending a downward eaves 3 over the entire circumference, and is provided on the parallel two frames 1a, 1a of the window frame 1 in detail later. In the fully closed state in which the lower surface of the outer peripheral portion of the shoji 2 is in contact with the upper end surface of the window frame 1, the window frame 1 is supported by a pair of opening / closing devices.
The portion below the contact surface with the shoji 2 is covered from the outside by the eaves 3 of the shoji 2, so that rainwater can be prevented from entering the room through the gap between the window frame 1 and the shoji 2. There is.

Next, the opening / closing device will be described. On the inner peripheral surface of the parallel two frames 1a, 1a of the window frame 1, an elongated sliding hole 6 having a circular cross section and a communication opening from the hollow to the outer surface of the sliding hole 6 are provided. The elongated fixed frames 5 and 5 formed with the grooves 7 are fixed in a state where the sliding holes 6 are parallel to each other and slightly inclined with respect to the horizontal. A pair of upper and lower elongated guide grooves 8 and 8 and an elongated rail 10 having an upper surface serving as a sliding contact surface 11 are formed in parallel with the slide hole 6, and the slide hole 6 has a core wire A geared cable 12 formed by spirally winding a single metal wire around the outer periphery with a constant pitch is inserted in a substantially tight and sliding manner.
The drive-side ends of 2 and 12 are arranged along the parallel two frames 1a and 1b orthogonal to the parallel two frames 1a, and meshed with one drive gear 14 supported in the gear box 13 so that the gear box 13
By driving the electric motor 15 fixed to the drive gear 14 to rotate the drive gear 14, the two geared cables 12 and 12 slide in the sliding holes 6 at the same direction and speed.

A slider 16 having a U-shaped cross section, which supports a pair of upper and lower rollers 17 and 17 at two positions spaced apart in the horizontal direction, is mounted on the fixed frame 5 in a guide groove 18. The slider 16 is mounted so that it can move in parallel with the geared cable 12, and a spiral hole is formed in the inner circumference and a driven gear 21 is formed in the outer circumference between the upper and lower plates of the slider 16. The internal threaded body 20 formed by connecting the axis line to the geared cable 12
The driven gear 21 is rotatably supported in a substantially vertical direction at right angles to the geared cable 12 through the communication groove 7 of the sliding hole 6 and is immovable in the vertical direction.

The slider 16 has a U-shaped cross section in which the distance between the upper plate and the lower plate is larger than that of the slider 16, and a vertical screw rod 26 is provided between the upper plate and the lower plate to rotate about the axis and move in the axial direction. The movable support 25, which is fixedly fixed to the female screw body 20,
When the geared cable 12 is moved relative to the slider 16 in the fenestration direction that is rightward in FIGS. 4 and 5, the female screw body 20 is driven by the geared cable 12 when the geared cable 12 is moved relative to the slider 16. When the gear rod 21 and the geared cable 12 are rotationally driven by meshing with each other, the screw rod 26 is screwed upward and the movable support 25 is moved upward with respect to the slider 16. By the movement of the cable 12 in the window closing direction opposite to the above, the screw rod 26 is screwed downward and the movable support 25 is moved downward.

At the upper position of the movable support body 25, an elongated elevating frame 27 which is substantially parallel to the fixed frame 5 is interposed between both ends of the movable frame 25 and both ends of the fixed frame 5, and is operated in conjunction with a connecting rod 29. Supported by a pair of λ-shaped links 28a, 28b, the elevating frame 27, by fitting the roller 31 on the upper surface of the movable support 25 in the guide groove 30 in the length direction opening to the lower surface, The movable support 25 is supported from below to move integrally up and down.
However, bracket one end of the frame and the upper surface of the movable support 25.
A roller 34 that rolls on the upper surface of the elevating frame 27 is connected at the end on the bracket 33 side of the lower surface of the shoji 2 while being connected so as to move integrally by being joined at 33. Other rollers 35 rolling on the lower surface of the shoji 2 are supported on the upper surface of the elevating frame 27 at the end portion on the opposite side to the movable support 25 and the elevating frame.
It is supported so as to move up and down integrally with 27 and to move relative to the elevating frame 27 integrally with the movable support 25 in the longitudinal direction thereof. Further, since the pair of λ-shaped links 28a and 28b supporting the elevating frame 27 have different link lengths from each other, the elevating frame 27 will be As shown in FIG. 6, when the shoji 2 is raised horizontally to a predetermined height above the window frame 1 while keeping a horizontal posture, as shown in FIG. It is inclined so as to take a posture parallel to the geared cable 12 in the sliding hole 6 not shown in the figure.

On the slider 16, a plate-like connecting body 36 formed by projecting a horizontal sliding contact pin 37 perpendicular to the sliding hole 6 is freely rotatable by a support shaft 38 parallel to the sliding contact pin 37. Moreover, the sliding contact pin 37 is fixed to the rail of the fixed frame 5 by the elasticity of the torsion coil spring 39.
A pair of high and low claw portions 40, which are supported in a state in which a rotational force in a direction of abutting against the sliding contact surface 11 of 10 is urged and which project upward and have different upper ends, are formed on the connecting body 36. , 41 are formed with a certain width, while the geared cable 12 has a terminal tool 43 fixed to the driven end of the sliding hole 6, and the terminal tool 43 has a connector 36 of a connecting body 36. A connecting pin 45 having a diameter that fits closely between the claws 40 and 41 is formed so as to project toward the slider 16 in parallel with the support shaft 38 of the connecting body 36, and the sliding contact pin 37 slides on the rail 10. When the contact pin 11 is in contact with the contact surface 11, the connection pin 45 is fitted between the claws 40 and 41, so that the geared cable 12 and the slider 16 move integrally in both the opening and closing directions via the connection body 36. In addition, the sliding contact pin 37 is fitted into the recess 46 formed at one end of the rail 10 so that the connecting body 36 can be connected to both sides. In a state in which the parts 40 and 41 are rotated downward while being in an oblique posture, the upper claw part 40 remains protruding above the height of the connecting pin 45 of the geared cable 12 and the upper end of the lower claw part 41 is kept. By being located below the height of the connecting pin 45, the geared cable 12 approaches the connecting body 36 with the window closing direction in which the connecting pin 45 is detached from between the claw portions 40 and 41 and is separated from the connecting body 36. It can move relative to the slider 16 in both directions of the window opening.

This embodiment has the above-described structure, and in the fully closed state in which the shoji 2 comes into contact with the upper end of the window frame 1 and closes the opening thereof, as shown by the solid line in FIG. Is separated from the connecting body 36 to the left in the figure, and the slider 16 is connected to the sliding contact pin of the connecting body 36.
The movement of the rail 37 is restricted because the rail 37 is held in the recess 46 of the rail 10. When the electric motor 15 is driven in one direction from this state, the geared cable 12 relatively moves in the fenestration direction with respect to the slider 16 which is held immovable, while the connecting pin 45 approaches the connecting body 36, the internal thread body is formed.
Movable support 25 by screwing screw rod 26 by rotation of 20,
The elevating frame 27 and the shoji 2 move upward, the eaves 3 of the shoji 2 reaches above the upper end of the window frame 1, and the elevating frame 27 is moved to the geared cable 12.
The connecting pin 45 pushes the higher claw portion 40 over the lower claw portion 41 of the connecting body 36 when it becomes parallel to the connecting body 36, and the connecting body 36 biases the torsion coil spring 39 by this pressing force. In contrast, as shown by the chain line in FIG.
The connection pin 45 is sandwiched between the two claws 40, 41 by rotating the claws 40, 41 so as to be detached upward from the recess 46 and changing the direction of the two claws 40, 41 to the standing posture. The geared cable 12 and the slider 16 are connected to each other, and thereafter, the relative movement of the geared cable 12 with respect to the slider 16 is blocked and the rotation of the female screw body 20 and the screw rod 26 are stopped from moving. And the lifting frame 27 is prevented from moving upward with respect to the slider 16, and as shown in FIG.
The slider 16 and the movable support 25 are in sliding contact with the sliding contact surface 11 of 10
Moves in unison with the geared cable 12, and the shoji 2 moves in unison with the slider 16 while being guided by the elevating frame 27 without causing the eaves 3 to interfere with the window frame 1, so that the shoji 2 gradually becomes a window. The protrusion of the frame 1 to the side increases the opening of the window.

At this time, the elevating frame 27 is in an inclined posture in which the side on which the shoji 2 protrudes is slightly upward. However, if the protruding amount of the shoji 2 becomes large, as shown in FIG. Bracket 33 and roller 34 at the connecting part of shoji 2
However, as the roller 35 of the elevating frame 27 approaches the fulcrum position for supporting the shoji screen 2, it becomes a cantilever state. As a result, the protruding side of the shoji screen 2 is lowered, and the shoji screen 2 takes a horizontal posture in the fully opened state.

When closing the window from the open state, use the geared cable 12
Is moved in the opposite direction to the above, the slider 16 moves integrally with the geared cable 12, and
Since the rotation of 20 and the screw rod 26 are prevented from moving forward, the movable support 25 moves integrally with the slider 16 without moving downward, and the shoji 2 is guided by the elevating frame 27. When the shoji 2 moves above the window frame 1 so as to cover the opening and reaches the position where the shoji 2 aligns above the window frame 1, the connecting body 36 rotates and the sliding contact pin 37 causes the rail 10 to move.
The slider 16 is prevented from moving by being fitted into the concave portion 46, and the lower claw portion 41 tilts below the connecting pin 45, so that the connecting pin 45 is disengaged from between the both claw portions 40, 41. The connection between the geared cable 12 and the slider 16 is released, and thereafter, the female screw body 20 is opened as the geared cable 12 moves relative to the slider 16 while separating the connection pin 45 from the connection body 36. By rotating in the direction opposite to the window direction, the screw rod 26 is screwed downward, the movable support 25 is moved downward, and the elevating frame is in an oblique posture.
Move down while changing the posture so that 27 and shoji 2 become horizontal,
When the shoji screen 2 becomes horizontal, it abuts on the window frame 1 to close the window.

In this embodiment, the geared cable 12 is used as the toothed driving member, but other than this, a chain, a toothed belt, a rack, or the like may be used, and these are used as the toothed driving member. In this case, suitable meshing portions such as a sprocket, a spur gear, and a pinion may be formed on the outer circumference of the female screw body 20, respectively.

The present invention is not limited to the skylight described in the above embodiment,
A window frame having a vertical vertical frame and horizontal upper and lower frames is attached to the wall surface to open and close other types of windows that allow the shoji to move in parallel in the vertical or horizontal direction while slightly projecting to the outdoor side. It is also applicable to the case.
