Description

Description: INDUSTRIAL APPLICABILITY The present invention is provided at substantially corresponding central positions of horizontal frames or vertical frames corresponding to each other of a fixed frame fitted in a window hole provided in a building. The present invention relates to a rotating window in which a window plate in which a cover plate such as a glass plate is stretched in a rotating frame is rotated about a support shaft so as to be opened and closed.

2. Description of the Related Art Problems to be Solved by the Prior Art and Invention Conventional rotary windows, whether manually pushed or opened, are generally driven by a motor or a motor drive. It is designed to rotate and open and close, and when a large wind pressure acts, an excessive load is applied to the drive unit and deformation and wear are likely to occur, and when the window plate is strongly pressed from the outside, the drive unit reverses. Since there is a problem in crime that it can be pushed open by breaking or breaking, it is necessary to separately provide a locking device so that the window plate does not rotate due to external force at the time of opening the window and when closing the window, In addition, there is a drawback in that the structure is complicated in order to be able to lock so as not to rotate at an arbitrary opening degree, the cost is increased, and the bulkiness is uncomfortable.

Means for Solving the Problems As a means for solving such problems, the present invention supports a drive shaft in which an eccentric shaft is continuously provided on a fixed frame, and a pair of external gears and internal teeth that mesh with each other. An arm in which one of the gears is concentric with the drive shaft and is fixed to the fixed frame, the other of the pair of gears is concentrically and rotatably supported by the eccentric shaft, and the base end is fixed to the other gear. A drive mechanism is provided, the tip of which is engaged with a guide portion formed on the rotating frame of the window plate, and the drive shaft of the drive mechanism is connected to an electric or manual drive source.

Advantageous Effects and Effects of the Invention The present invention has the above-described structure, and when the drive shaft is rotated manually or by driving a motor, the eccentric shaft revolves around the time of driving, and the other one supported by the eccentric shaft. The gear of, by meshing with one gear fixed concentrically with the drive shaft, rotates around the eccentric shaft while revolving around the drive shaft, and at the same time, the arm fixed to the other gear is By rotating the base end part around the drive shaft while rotating about the eccentric shaft, the base end part is swung about the center as a whole, and the window plate is driven in the window opening direction or the window closing direction, and the drive shaft is rotated. When stopped, the meshing of both gears prevents the arm from swinging and locks the position and posture of the window plate, so that in the open window state, the window plate is prevented from being shaken by wind and rattling. When the window is closed, remove the locking device. Even if it is not attached, the window plate is locked so that it cannot be opened forcefully from the outside, and even if the drive shaft of the drive mechanism is eccentric with the support shaft of the window plate, the arm is located on the support side of the window frame rotation frame. Since it swings along the frame, it is arranged so as to be hidden between the fixed frame and the rotating frame, and it does not obstruct the eyes,
Further, the drive mechanism can be attached to the substrate to form a unit, which has the effect of significantly simplifying the attachment work.

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

1 to 5 show a first embodiment of the present invention, in which a rotary window to which the present embodiment is applied has a window hole b formed through a wall surface a of a building.
A fixed frame 1 is fitted to the fixed frame 1, and a window plate 5 in which a glass plate 7 is stretched on a rotary frame 6 is fitted to the fixed frame 1 and provided at the center of the vertical frame 2 on both left and right sides of the fixed frame 1. It rotates around the support shaft 9 to open and close.

A drive unit 10 for rotating the window plate 5 is attached to each of the center portions of the vertical frames 2 on the left and right sides of the fixed frame 1 described above, and the drive unit 10 is shown in FIG. 4 and FIG. As shown in detail, a drive shaft 13 in which an eccentric shaft portion 14 having a large diameter is integrally formed at an end of a base plate 11 and a mounting plate 12 which is fixed in parallel with the base plate at a distance is attached to the mounting plate. 12 through holes 12
The eccentric shaft portion 14 is fitted into the gap between the base plate 11 and the mounting plate 12 while penetrating a, and the journal 15 projecting from the end face of the eccentric shaft portion 14 is fitted into the bearing hole 11a of the base plate 11. Thus, the internal gear 17 on the surface of the base plate 11 on the side of the mounting plate 12 is fixed concentrically with the drive shaft 13 while being supported rotatably and incapable of slipping out in the axial direction. Number of internal gear 17
One to several fewer external gears 18 than the central hole 18
a is concentrically and rotatably fitted onto the eccentric shaft portion 14 of the drive shaft 13 and is meshed therewith.The radially toothed arm 20 is integrally formed with an arm 20 protruding in the radial direction, and a roller 21 is provided at the tip thereof. The mounting plate 12 of the drive unit 10 is axially supported and is attached to the central portion of the vertical frame 2 of the fixed frame 1, and the boss shape projecting concentrically with the drive shaft 13 on the surface of the substrate 11 on the rotary frame 6 side. Support shaft 9
Is a bearing plate 23 attached to the center of the left and right frames of the rotary frame 6.
The rotary frame 6 is fitted in the bearing hole 24 of the rotary shaft 6 so as to rotate about a support shaft 9 which is concentric with the rotary frame 13 when driven, and the roller 21 at the tip of the arm 20 is rotated by the rotary frame. 6
The guide rails 25 are formed along the left and right frames of the.

A gear box 27 that fits inside the vertical frame 2 is attached to the outer surface of the mounting plate 12 of the drive unit 10 described above, and
A screw gear 28 is formed on a portion of the gear box 27 projecting into the gear box 27, and is meshed with a screw gear 30 formed on a connecting shaft 29 supported by the gear box 27 in a vertical posture orthogonal to the drive shaft 13. As shown in the figure, the upper end of a vertical power transmission shaft 31 whose lower end is connected to this connecting shaft 29 passes through the vertical frame 2, and the bevel gears 33 in the gear box 32 attached to the upper end of the vertical frame 2 mesh with each other. The other end of a horizontal power transmission shaft 34, which is connected to one of the 33 and one end of which is connected to the other bevel gear 33, passes through the horizontal frame 3 and is opposed to the inside of a gear box 35 attached to the central part of the horizontal frame 3. A bevel gear 37, which is connected to the bevel gears 36, 36 and meshes with both bevel gears 36, is connected to an operating handle 38 and is rotationally driven in both forward and reverse directions.

This embodiment has such a structure. By rotating the operation handle 38 in one direction, the drive shaft 13 of both drive units 10 is moved to the front side of FIGS. 5 and 3 via the power transmission shafts 34 and 31. When rotated clockwise when viewed from the side, as the eccentric shaft portion 14 revolves around the axis O of the drive shaft 13 in the same direction, the external gear 18 meshes with the internal gear 17 by meshing. , An arm 20 protruding from the external gear 18 while rotating around the axis O of the drive shaft 13 in the clockwise direction and rotating in the counterclockwise direction about the axis P of the eccentric shaft portion 14 while revolving in the clockwise direction. But the tip roller
While rolling 21 on the guide rail 25 of the rotary frame 6, the drive shaft 13 is swung in a counterclockwise direction along a locus shown by a chain line in FIG. When the window is rotated counterclockwise about 9 to close the window, and the operation handle 38 is rotated in the opposite direction to rotate the drive shaft 13 in the counterclockwise direction, the arm 20 draws the same locus, which is contrary to the above. By swinging clockwise, the window plate 5 rotates clockwise to open the window, and when the rotation of the drive shaft 13 is stopped in the open state, the external gear 18 and the internal gear 17 are separated from each other. Since the arm 20 is locked so as not to swing due to the meshing, the window plate 5 is held at an arbitrary opening without being rattled even if strong wind blows and rattling, and the drive shaft is closed when the window is closed. When 13 is stopped, the swing of the arm 20 is locked and the window plate 5 cannot be opened by hand. It is locking the 閉窓 state without attaching a locking device.

Further, in the first embodiment, the drive shaft 13 of the drive unit 10 is arranged concentrically with the support shaft 9 which is the center of rotation of the window plate 5, so that it acts on the window plate 5 when the arm 20 swings. Since a force to act on the window plate 5 can be applied in a direction perpendicular to the window plate 5, the opening and closing drive can be efficiently performed with a small force, and the arm 20 is completely disposed between the rotary frame 6 and the fixed frame 1 especially when the window is closed. The window plate 5 is driven by a pair of drive units 10 mounted on the vertical frames 2 on the left and right sides of the fixed frame 1, so that the window plate 5 can be opened and closed in a well-balanced manner. It is possible to

In the present embodiment, the internal gear 17 is fixed to the base plate 11 and the arm 20 is formed on the external gear 18, but on the contrary, the external gear 18 is fixed to the base plate 11 and the internal gear is fixed. Arm on gear 17
20 may be formed.

Further, the connecting portion between the drive shaft 13 and the connecting shaft 29 and the connecting member between the vertical power transmitting shaft 31 and the horizontal power transmitting shaft 34 include a direction changing mechanism such as a screw gear, a bevel gear, or a worm / worm wheel. You can use any of them,
Further, if a flexible shaft such as a flexible wire that can be rotated around the shaft center in a bent state is used as a power transmission shaft for transmitting the operating force of the operation handle 38 to the drive shaft 13, the two orthogonal axes can be connected. A direction changing mechanism such as a bevel gear is unnecessary.

The second embodiment shown in FIGS. 6 and 7 shows an example in which the drive shaft 13 of the drive unit 10 is arranged at an eccentric position with respect to the support shaft 9a which is the rotation center of the window plate 5, and the first embodiment is shown. A pair of drive units 10 similar to the above are mounted by a bracket 40 at a position projecting toward the indoor side slightly above the central portion of the vertical frame 2 of the fixed frame 1, and the roller 21 at the tip of the arm 20 is rotated by the rotary frame 6.
Are fitted on guide rails 25a formed on the indoor side surfaces of the left and right frames, and the drive shafts 13 of both drive units 10 are rotated via the power transmission shafts, so that the arms 20 are substantially centered on the drive shafts 13. By swinging along the locus shown by the chain line in FIG. 6, the window plate 5 is rotated about the support shaft 9a to open and close, and the drive shaft 13 is supported by the drive shaft 13 as in this embodiment.
When it is eccentric with 9a, there is a degree of freedom in the mounting position of the drive unit 10, and there is an advantage that it can be mounted in a place with sufficient space.

Further, instead of driving the drive shaft 13 by manually rotating the operation handle 38, for example, when the bevel gear 37 connected to the operation handle 38 illustrated in the first embodiment is rotated by a reversible motor. Alternatively, the drive unit 10 may be provided only on one side of the vertical frame 2 of the fixed frame 1, and the drive shaft 13 may be manually operated, by the motor, or by using the manual and the motor together. The window plate 5 may be rotated by driving, or when the rotating window is installed at a high place of the building, the drive shaft of the drive unit 10 may be rotated.
It is only necessary to connect 13 and a handle-operated rotating shaft attached to the lower part of the building through a chain and a sprocket so that the window plate can be opened and closed by operating the handle on the lower part of the building.

Further, the device of the present invention is similarly applied to a rotating window of a type in which a window plate is rotated around vertical support shafts provided at positions corresponding to each other in a central portion of a corresponding horizontal frame of a fixed frame. It is possible.
