Description

  The present invention relates to a window opening / closing operation device. In particular, the present invention relates to a window opening / closing operation device capable of closing a window by winding a wire fixed to the window and opening the window by releasing a holding state of the wound wire.

Conventionally, a window opening / closing operation device is obliged to be capable of “opening a window with one touch”. In such a window opening / closing operation device, one end of the wire is connected to the rotating window, and the rotating window can be closed by turning the operation handle and winding the wire around the winding drum. The rotating window is provided with a damper mechanism. When opening a rotating window, the window can be opened with one touch by pressing a “push button”. In such a window opening / closing operation device, the take-up drum gear integral with the take-up drum meshes with a drive gear that is rotationally driven by the operation of the handle, and meshes with a lock gear. When the open button is set to the return position, the operating body moves and the lock claw engages the lock gear. When the open button is in the pushed-in position, the lock pawl is released from the lock gear. (For example, refer to Patent Document 1 and Patent Document 2).
Another conventional type of window opening / closing operation device has a first gear and a second gear fixed to a first shaft, and one end thereof is rotatable with sliding resistance with respect to the first shaft. A supporting lever; a second shaft rotatably supported at the other end of the lever; a third gear fixed to the second shaft and meshing with the first gear; And a fourth gear that is movably supported and meshes with the first gear. The fourth gear can mesh with the drum gear of the winding drum. A one-way clutch (one-way clutch) is provided for the fourth gear. When the first shaft is rotated clockwise by the manual operation member, the lever rotates clockwise and the fourth gear meshes with the drum gear. When the first shaft is rotated clockwise in this state, the drum gear rotates clockwise, the wire is wound around the winding drum, and the window is closed. On the other hand, when the first shaft is rotated counterclockwise by the manual operation member, the lever rotates counterclockwise and the fourth gear is separated from the drum gear. At this time, the wire wound around the winding drum is drawn out by the dead weight of the window and the window is opened (see, for example, Patent Document 3). A general structure of a one-way clutch (one-way clutch) is described in Mechanical Engineering Handbook [B1] Machine Element Design / Tribology etc. (for example, see Non-Patent Document 1).

With this configuration, it is possible to reliably prevent the reverse rotation of the second gear. In the window opening / closing operation device according to the present invention, it is preferable that the first gear driving means includes a one-way clutch for the operation member provided between the operation member and the first gear. With this configuration, when winding the wire, the operating member can be rotated in the winding direction of the wire, and the first gear can be rotated in the same direction as the operating member such as a handle, and the opposite direction to the winding direction of the wire When the operating member is turned in the direction, the operating member can be idled with respect to the first gear.

  The window opening / closing apparatus according to the present invention operates as follows. In the open state of the rotary window, the wire is fed from the winding drum. When closing the rotating window, the first gear is rotated by the driving means. When the first gear rotates, torque is applied to the swing lever by the slip torque applying means, and the swing lever swings from the first position to the second position as the first gear rotates.

The rotation of the first gear is transmitted to the second gear, and the winding drum gear is rotated by the rotation of the second gear, and the wire is wound. When the operation of the driving means is stopped until the rotating window is completely closed or when it is closed to a desired opening, the wire is pulled by the weight of the rotating window or by the force in the opening direction of the rotating window by the window opening mechanism. The take-up drum gear tries to reverse. However, since the reverse rotation of the second gear meshing with the take-up drum gear is prevented by the reverse rotation preventing means, the wire is prevented from being fed out, and the rotating window is held in the closed state or at a desired opening position.

  On the other hand, in order to open the rotary window, the gear release mechanism is operated to move the swing lever from the second position to the first position, thereby releasing the engagement between the second gear and the take-up drum gear. As a result, the take-up drum that rotates integrally with the take-up drum gear is freely rotatable, the wire is fed out, and the rotating window is opened.

  The window opening / closing operation device of the present invention is quick and easy to open the rotating window. Further, the window opening / closing operation device of the present invention has a small number of parts constituting the device and a simple structure of the device. Therefore, the window opening / closing operation device of the present invention is very unlikely to cause a failure. Moreover, since the window opening / closing operation device of the present invention has a structure in which a wire is wound by a gear train, the rotating window can be closed by winding the wire with a light operating force. Furthermore, in the window opening and closing operation device of the present invention, since the centrifugal governor brake is incorporated in the winding drum, the device can be configured compactly.

Although two swing lever packings 122a and 122b are illustrated in the embodiment of the present invention, the number of swing lever packings may be one or two or more. The swing lever 120 is also swung in the clockwise direction so that a swing lever positioning portion (not shown) formed on the box body 104 is positioned so that the gear portion of the carrier gear 140 is engaged with the gear portion of the take-up drum gear 112. ).

  The second gear, that is, the carrier gear 140 is supported so as to be rotatable with respect to the carrier gear shaft 141 fixed to the swing lever 120. The gear portion of the carrier gear 140 is configured to always mesh with the gear portion of the drive gear 130. The carrier gear 140 is disposed between the upper plate 108 and the box body 104.

There may be one intermediate transmission gear or a plurality of intermediate transmission gears.

  Referring to FIGS. 3, 6, and 7, a handle 150 constituting an operation member for rotating the drive gear 130 is disposed outside the upper plate 108. The handle 150 is configured to be folded at the base and accommodated in the upper plate 108 when not in use. The handle 150 and the drive gear 130 are connected via a gear connecting member 151. The base 150b of the handle 150 constitutes drive gear driving means. As a modified example, the drive gear driving means can be constituted by a power source, a motor rotated by the power source, a gear box rotated by the motor, and the like. The handle 150 may be configured so that it can be detached from the upper plate 108 when not in use. The drive gear 130 can be rotated when the handle 150 is rotated in one direction, and the handle 150 is slipped with respect to the drive gear 130 when the handle 150 is rotated in the other direction (reverse direction).

The gear one-way clutch 143 constitutes a reverse rotation preventing means for the gear portion of the carrier gear 140. In this embodiment, a structure in which the gear one-way clutch 143 is provided for the carrier gear 140 will be described. However, the gear one-way clutch 143 can also be provided for the drive gear 130. Alternatively, a transmission gear may be provided between the carrier gear 140 and the drive gear 130, and a gear one-way clutch 143 may be provided for the transmission gear. Typical structures and operating principles of the gear one-way clutch 143 and the steering wheel one-way clutch 132 are described in Non-Patent Document 1, for example. As such a one-way clutch, for example, a “shell type roller clutch” sold by Nippon Seiko Co., Ltd. can be used.

  Referring to FIGS. 1 to 5 and FIG. 11, when the swing lever 120 swings, the carrier gear 140 is moved to a first position where the gear portion of the carrier gear 140 meshes with the gear portion of the take-up drum gear 112, that is, wire winding. It is configured to be able to move between the take-up position (see FIG. 1) and the second position where the gear portion of the carrier gear 140 does not mesh with the gear portion of the take-up drum gear 112, that is, the wire release position (see FIG. 11). Is done.

  The window opening / closing operation device 100 further includes a gear release mechanism 160 for moving the carrier gear 140 from the wire winding position to the wire release position. The gear release mechanism 160 moves in parallel with the rotation center axis of the carrier gear 140 to disengage the gear portion of the carrier gear 140 from the gear portion of the take-up drum gear 112. A roller 164 provided for the swing lever 120 and configured to come into contact with the gear release shaft 162, and a shaft return spring 166 for returning the gear release shaft 162 to the inoperative position. Configured as follows. The gear release shaft 162 includes a push button portion 162a, an operating portion 162b, and a spring receiving portion 162c.

The outer peripheral cylindrical surface of the roller 164 is disposed at a position where it can come into contact with the operating portion 162b of the gear release shaft 162. The shaft return spring 166 can be formed of, for example, a coil spring. The upper part of the shaft return spring 166 is received by the spring receiving portion 162 c of the gear release shaft 162. A lower portion of the shaft return spring 166 can be disposed in the box body 104. The movement direction of the gear release shaft 162 is preferably arranged in parallel with the rotation center axis of the winding drum 110. The central axis of the cylindrical surface of the roller 164 is preferably arranged so as to be perpendicular to the moving direction of the gear release shaft 162.

(1.2) Operation of the first embodiment:
Next, the operation of the first embodiment of the window opening / closing operation device of the present invention will be described. With reference to FIGS. 1 to 7 and 9, one end (that is, the end on the front end side) of the wire 102 is attached to the rotating window 182. The other end of the wire 102 (that is, the proximal end) is attached to the winding drum 110. When closing the rotary window 182, the tip of the handle 150 is pulled out and inverted so that the handle 150 can be rotated. When the handle 150 is rotated in the clockwise direction, the drive gear 130 is rotated in the clockwise direction (see arrow AR1 in FIG. 1). When the handle 150 is rotated in the clockwise direction, the clutch housing 135d is rotated to rotate the clutch shaft 130d via the roller 133. In this state, when the roller 133 is locked between the clutch housing 135d and the clutch shaft 130d so as to be in a wedge state, the rotation of the handle shaft 150b of the handle 150 is reliably transmitted to the clutch shaft 130d. When the handle 150 is rotated counterclockwise, the wedge state is released between the roller 133 between the clutch housing 135d and the clutch shaft 130d, and the roller 133 escapes from the groove portion of the latch shaft 130d. In this state, even if the handle 150 is rotated counterclockwise, the handle shaft 150b, the clutch housing 135d, and the roller 133 rotate counterclockwise, but the clutch shaft 130d does not rotate. Accordingly, when the handle 150 is rotated in the clockwise direction by the action of the one-way clutch 132 for the handle, the drive gear 130 can be rotated in the clockwise direction. However, even if the handle 150 is rotated in the counterclockwise direction, the drive gear 130 is rotated. 130 does not rotate. Since the swing lever packings 122a and 122b have a tightening margin with respect to the central shaft 130b of the drive gear 130 and a tightening allowance with respect to the swing center hole 120b of the swing lever 120, the drive gear 130 rotates clockwise. When rotating in the direction, the swing lever 120 also swings in the clockwise direction, and is positioned at a position where the gear portion of the carrier gear 140 meshes with the gear portion of the take-up drum gear 112.

  When the handle 150 is further rotated in the clockwise direction in this state, the carrier gear 140 is rotated in the counterclockwise direction by the rotation of the drive gear 130 (see the arrow AR2 in FIG. 1). When the carrier gear 140 rotates counterclockwise, the gear one-way clutch 142 operates so that the carrier gear 140 can rotate. As the carrier gear 140 rotates, the take-up drum gear 112 rotates integrally with the take-up drum 110 in the clockwise direction (see arrow AR3 in FIG. 1). When the winding drum 110 rotates, the wire 102 can be wound around the outer periphery of the wire winding portion of the winding drum 110. When the carrier gear 140 attempts to rotate clockwise, the gear one-way clutch 143 operates so that the carrier gear 140 prevents rotation. In this state, the gear portion of the carrier gear 140 remains engaged with the gear portion of the take-up drum gear 112, and since the gear one-way clutch 143 is provided on the carrier gear 140, the take-up drum 110 does not rotate in reverse. Absent. As described above, the rotary window 182 can be closed by rotating the handle 150 in the clockwise direction and winding the wire 102.

When opening the rotary window 182, the push button part 162 a of the gear release shaft 162 is pushed with a finger, and a force is applied to the outer peripheral cylindrical surface of the roller 164 by the operating part 162 b of the gear release shaft 162. When the outer peripheral cylindrical surface of the roller 164 is pressed, the swing lever 120 swings counterclockwise, and the gear portion of the carrier gear 140 is positioned at a position away from the gear portion of the take-up drum gear 112. When the gear portion of the carrier gear 140 is separated from the gear portion of the take-up drum gear 112, the take-up drum 110 can be rotated. Therefore, the rotary window 182 can be opened by its own weight or by the action of a biasing device for opening the window (for example, a damper device). When the take-up drum 110 rotates, the brake wheel 115 is rotated at an increased speed through the rotation of the transmission gears 114a and 114b. When the brake wheel 115 rotates, the four brake pieces 116 a to 116 d move so as to spread outward by centrifugal force, and come into contact with a brake shoe 117 provided on the inner surface of the take-up drum 110. Until the rotational speed of the brake wheel 115 reaches a predetermined value, the brake pieces 116a to 116d do not spread outward by the force of the coil spring of the brake wheel 116f.
When the rotational speed of the brake wheel 115 reaches the predetermined value, the centrifugal force of the brake wheel 116f exceeds the tightening force of the coil spring, and the brake pieces 116a to 116d open outward. Therefore, the rotational speed of the winding drum 110 can be adjusted by the action of the centrifugal governor brake configured as described above. With this configuration, the rotating window 182 is not opened with force, and the opening speed of the rotating window 182 is adjusted to an appropriate speed by the action of the centrifugal governor brake, and the rotating window 182 is opened. When the operation of pushing the gear release shaft 162 is stopped and the finger is released from the gear release shaft 162, the gear release shaft 162 is returned to the inoperative position by the spring force of the shaft return spring 166.

(1/3) Structure of a modification of the first embodiment:

(1.4) Operation of the modification of the first embodiment:
In the modification of the first embodiment of the window opening / closing operation device of the present invention, the operation when the rotating window 182 is closed by rotating the handle 150 in the clockwise direction is the same as that of the first embodiment of the present invention described above. This is the same as the operation. The difference is that the lever pressing spring 170B applies a force in a direction in which the swing lever 120B is pressed against the take-up drum gear 112.

  When opening the rotary window 182, the push button portion of the gear release shaft 162B is pushed, and the outer peripheral cylindrical surface of the roller is pushed by the operating portion of the gear release shaft 162B. When the outer peripheral cylindrical surface of the roller is pressed, the swing lever 120B swings counterclockwise, and the gear portion of the carrier gear 140 is positioned at a position away from the gear portion of the take-up drum gear 112. When the gear portion of the carrier gear 140 is separated from the gear portion of the take-up drum gear 112, the take-up drum 110 can be rotated. Therefore, the rotary window 182 can be opened by its own weight or by the action of a biasing device for opening the window (for example, a damper device). The gear release shaft 162B is held at the release position by the shaft holding mechanism. By operating the shaft holding release mechanism, the holding of the gear release shaft 162B can be released.
