Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a swing device for a sliding window having a tilt-preventing function.

[Conventional technology]

For example, Japanese Unexamined Utility Model Publication No. 57-12146 and Japanese Unexamined Utility Model Publication No. Sho 63-28769 disclose a swing device having an anti-raising function.

A folding link type swing device to which the present invention is applied is disclosed in, for example, Japanese Utility Model Laid-Open No. 2-9671,
These are known from JP-A-63-46575 and JP-A-59-161570. As shown in FIGS. 3 and 6, this swing device has at least three links, and the maximum swing angle of each link is 90 degrees or less, so that the opening and closing operation of the window is smooth. And

[Problems to be solved by the invention]

In the conventional swing device having the anti-tilt function, the window can be fixed only at two positions, that is, the fully open position and the half open position. Therefore, at the time of ventilation, the window must be at least half-opened, and there is a disadvantage in that the airflow during ventilation cannot be freely changed. For example, there are problems when it is desired to ventilate but avoid rainfall, or when ventilating while preventing scattering of documents and the like.

The window when half-opened is inclined at an angle of about 45 degrees with respect to the opening surface, and the distance between the window surface on the swing front end side and the opening surface becomes considerably large. For this reason, there is a danger of falling due to mischief or negligence, and there are restrictions on application points in terms of safety.

If the dedicated anti-swing device is provided separately from the swing device, the above disadvantages can be eliminated. However, in this case, the disadvantage that the total cost of the sliding window increases cannot be avoided.

As one of means for avoiding an increase in cost, it is conceivable to add a swing control function to the swing device. However, this type of swing device is configured to be disposed in a small gap between the window and the window frame in the fully closed position, and adding an existing anti-tilt device is structurally or user-friendly. There is impossible. In particular, in the case of a folding link type swing device, the degree of difficulty is high because the links when fully opened are folded and stored in a state of being vertically overlapped.

Therefore, the purpose of the present invention is to realize a folding link type swing device having a tilt control function so that the opening of the window can be freely adjusted, and the cost is lower than when a dedicated tilt control device is added. The purpose of the present invention is to suppress the increase in the number of windows and to reduce the overall cost of this type of sliding window.

Another object of the present invention is to provide a highly reliable swing device that can reliably maintain a window opening posture even when it is subjected to an alternating load due to fluttering of a window or an impact due to a gust.

[Means for solving the problem]

According to the present invention, a shift link 5 for sliding the window 2 or a control link 7 for regulating the maximum swing angle of the shift link 5 is an operation target, and a restraint link 21 connected to the target link and a pinion 26 are connected. In addition, the opening degree of the window 2 is adjusted by the locking means 22 having the rack body 25 as an engagement element.

A folding link type swing device including three or more links has a form in which a short shift link is slid along a guide frame and a form in which a long shift link is slid along a guide frame. There is.

In the swing device applied to the former mode, the long first
Between the shift link 5 and the guide frame 3, a check link 21 for regulating the swing operation of the first shift link 5, and this link
Lock means 22 for regulating the displacement operation of 21 is provided. The locking means 22 includes a pair of rack bodies 25 arranged in parallel along the guide frame 3, a pinion 26 supported by the proximal shaft 31 of the restraint link 21 and engaged with both rack bodies 25 simultaneously, 26 includes a spring 27 that biases toward a locking position in which it engages with both rack bodies 25,
It is configured to be operable to switch between a locked position and an unlocked position via 31.

In the swing device applied to the latter mode, a restraining link 21 for regulating the swinging operation of the control link 7 is provided between the control link 7 for the first shift link 5 and the guide frame 3, and a displacement operation of the link 21. And lock means 22 for regulating the pressure.
The locking means 22 includes a pair of rack bodies 25 arranged in parallel along the guide frame 3, a pinion 26 supported by the base shaft 31 of the restraint link 21 and engaged simultaneously with both rack bodies 25,
A spring 27 for urging the pinion 26 toward a locked position in which the pinion 26 is engaged with the two rack bodies 25 so that the pinion 26 can be switched between a locked position and an unlocked position via the base shaft 31; Configure.

[Action]

Since the lock means 22 is configured by using the pair of rack bodies 25 and the pinion 26 as engagement elements, the pinion with respect to the rack body 25
By changing the meshing position of 26, the restraining link 21 can be locked at an arbitrary displacement position via the base shaft 31. This means that the first shift link 5 or the control link 7 is locked and fixed at an arbitrary swing position via the restraint link 21,
This means that the opening of the window 2 can be freely adjusted.

Since the first shift link 5 or the control link 7 is used as an operation target to lock the anti-raising, and the locking means 22 is mounted using the guide frame 3, the structure of the swing device is complicated. Can be prevented.

Since the link operation is prevented by the pinion 26 being engaged simultaneously with the pair of rack bodies 25, for example, a form in which the locked state is maintained by frictional force, a single rack body and an engagement piece that meshes with this As a result, the lock posture can be more firmly maintained than in the conventional anti-tilt mechanism that maintains the lock state. In addition, since the pinion 26 is constantly urged into the locked position by the spring 27, the locked position can be reliably maintained even when an external load such as an alternating load or an impact is received.

[Effect of the invention]

As described above, according to the swing device of the present invention, the first shift link 5 or the control link 7 that does not slide and displace with respect to the guide frame 3 is operated, and the first shift link 5 or the control link 7 is moved between the one link and the guide frame 3. Since the stopper mechanism is provided, the structure of the sliding window can be simplified as compared with the case where a dedicated tilt stopper is provided separately from the swing device, and the selling cost can be reduced accordingly.

Since the locking means 22 of the anti-raising mechanism is configured by using the pair of rack bodies 25 and the pinion 26 as engagement elements, the opening degree can be freely adjusted as compared with the conventional device, and particularly in the half-open state to the fully closed state. , The opening of the window 2 can be changed to be large or small.

The pinion 26 is urged to engage by a spring 27, and a pair of rack
As the pinion 26 is engaged simultaneously, the locking for stopping the detent is performed, so that the locked state can be maintained firmly and securely compared with the conventional locking posture maintaining structure. Even in the case where the swing device is received, the open posture of the window 2 is maintained, and the reliability of this type of swing device can be improved.

First Embodiment FIGS. 1 to 4 show a first embodiment of a swing device according to the present invention.

In FIG. 3, reference numeral 1 denotes a window frame, and 2 denotes a window. Window 2
A folding link type swing device is arranged between each of the upper and lower frames of the window frame 1 and the upper and lower frames of the window frame 1, and the window 2 is supported by this device so as to be freely opened and closed between a fully closed position and a fully open position. I have.

In the fully open position, the window 2 is in a position orthogonal to the window opening surface as indicated by a dashed line. Since the upper and lower swing devices differ only in the mounting direction, only the lower swing device will be described.

The swing device is provided with a guide frame 3 screwed to the side of the window frame 1, a mounting bracket 4 screwed to the window 2, and an operation of sliding the window 2 provided between the guide frame 3 and the mounting bracket 4. First and second shift links 5 and 6
The control link 7.8 controls the maximum swing angle of the two links 5.6, and a tilt-stop mechanism provided between the first shift link 5 and the guide frame 3.

The guide frame 3 is formed of a C-shaped frame having a pair of slide grooves 9 (see FIG. 4), and guides and supports a slider 10 that engages with the slide grooves 9 so as to be slidable left and right. At the left end of the guide frame 3, when closing the window 2,
A guide wall 12 is provided to guide the claw portion 4a at one end of the mounting bracket 4 to a proper stop position. At the center of the bottom wall of the guide frame 3, a stopper 13 for defining the sliding limit of the slider 10 is formed. At the right end of the bottom wall, a mounting boss 14 is formed to bulge upward.

The slider 10 and the claw portion 4a of the mounting bracket 4 are connected to each other by a short second shift link 6, and the mounting bracket 4
The midway portion and the mounting boss 14 are connected by the long first shift link 5 to support the window 2. When window 2 is opened and operated
The first shift link 5 swings outward with the pin 15 as a fulcrum, and pushes the window 2 toward the outer surface. The second shift link 6 swings outward with the pin 16 as a fulcrum while sliding close to the first shift link 5, and the
Window 2 centering on connecting pin 17 between
Is operated in the counterclockwise direction.

The proximal ends of the control links 7 and 8 are connected to the slider 10 via a shaft 18 provided at a position different from the pin 15 for the second shift link 6 in a co-tightening manner. Then, the free end of the long control link 7 is connected to the middle of the first shift link 5, and the free end of the short control link 8 is connected to the middle of the second shift link 6. The latter control link 8 has an elongated hole 19 for absorbing the swing operation of the second shift link 6, and is connected to the shaft 18 via the elongated hole 19.

In both control links 7 and 8, the slider 10 has the stopper 13
, The shift links 5 and 6 are prevented from swinging outward. The maximum swing angle of the second shift link 6 is larger than that of the first shift link 5, but at the maximum.
Set so that it does not exceed 90 degrees.

The anti-raising function includes a restraining link 21 that regulates the swing operation of the first shift link 5 and a lock unit 22 that regulates the displacement operation of the link 21.

In FIG. 4, the lock means 22 includes a rack frame 23 having a U-shaped cross section that opens downward, a pair of rack bodies 25 that are arranged in parallel along a guide groove 24 on the upper surface, and both rack bodies 25. It comprises a pinion 26 that engages at the same time, and a spring 27 that pushes and urges the pinion 26 toward the rack body 25.

Each rack body 25 is formed so that the tips of the engaging teeth 28 face each other, and the engaging teeth extend over substantially the entire length of the guide groove 24 except for a certain range on the closing stroke end side of the pinion 26. Form 28. This is because the lower frame covers the upper surface of the locking means 22 when the window 2 starts to open, and the pinion 26 cannot be unlocked.

The restraining link 21 has one end connected to the first shift link 5 by a pin 30 and the other end connected to the locking means 22 via a base shaft 31. Specifically, as shown in FIG. 1, a base shaft 31 is inserted into the guide groove 24 from the outer surface, and a pinion 26 is
Is caulked so that it can rotate relative to each other. A hole 32 that opens downward is formed in the base shaft 31, and the above-described spring 27 is mounted between the hole 32 and the bottom wall of the guide frame 3. When the window 2 is opened, the base shaft 31 and the pinion 26
The pinion 26 is maintained in the locked position (the state shown in FIG. 1) in which the pinion 26 is engaged with the two rack bodies 25 by the push-up operation.
When the pinion 31 is pressed down against the spring 27, the pinion 26 is switched to the unlocked position (the state shown in FIG. 2) in which the pinion 26 is lowered below the rack body 25 to release the engagement.

Next, the operation of the locking means 22 will be mainly described.
Is completely closed, the restraint link 21 and the lock means 22 are located between the first shift link 5 and the guide frame 3. At this time, the pinion 26 is located at the left end of the guide groove 24 as shown by the imaginary line in FIG. 4, and is located in a region where the engaging teeth 28 of the rack body 25 are not formed.

When the window 2 is opened from this state, the first shift link 5 pushes the window 2 while swinging outward, and at the same time, the second shift link 6 slides toward the first shift link 5 to remove the window 2. Push in the direction. Window 2 is pinion 26
Can be freely opened to a position where it comes into contact with the rack body 25, and at this opening limit position, the lower frame of the window 2 has passed outwardly on the upper surface of the base shaft 31.

As described above, when the proximal shaft 31 is pushed in against the spring 27, the pinion 26 switches to the unlocked posture. When the pushing force of the base shaft 31 is released after the window 2 is opened to the desired position in this state, the pinion 26 is pushed up by the spring 27 and engages with both rack bodies 25 at the same time.

Depending on the opening amount of the window 2, the engaging teeth of the pinion 26 and the engaging teeth 28 of the rack body 25 may be vertically overlapped and may not be able to mesh with each other. However, since the pinion 26 can freely rotate with respect to the base shaft 31, the window 2 can be slightly opened or
By pushing the base shaft 31 in and rotating it, the phase of the pinion 26 is shifted and the pinion 26 can be meshed with both rack bodies 25. Even if the user forgets to lock while simply opening the window 2, the pinion 26 is automatically locked to prevent the window 2 from suddenly opening and closing due to the wind and crashing into the window frame 1. it can. Further, since the pinion 26 rotates, the window 2 can be fixedly held at an arbitrary open position.

In the locked state, the pinion 26 and the rack body 25 are engaged in a horizontal plane. Therefore, even if the window 2 flaps or a large external force acts on the base shaft 31 due to a gust, a component force that pushes down the pinion 26 is prevented from being generated, and the opening of the window 2 is surely prevented. Hold posture.

When changing the opening of the window 2 or performing the closing operation, it is only necessary to push the base shaft 31 against the spring 27, and the opening can be adjusted very simply.

[Second Embodiment] FIG. 5 shows a second embodiment of the present invention in which the lock means 22 is changed. The first point is that the rack frame 23 is omitted, the rack body 25 is directly bonded to the guide frame 3, and the spring receiver 34 is fitted into the hole 32 slidably up and down, and the spring 27 is received by the spring receiver 34. Other than the embodiment, the other parts are substantially the same as the first embodiment.

Third Embodiment FIG. 6 shows a third embodiment of the swing device according to the present invention. The swing device includes a first and a second shift link 5.
A sliding groove in which the swing shaft 35 of the first shift link 5 is provided in the guide frame 3 by performing sliding operation of the window 2 by the three members 6 and the control link 7 for the first shift link 5.
The second embodiment differs from the first embodiment in that it is slidably supported along 36 and that a traction link 21 and a lock means 22 are provided between the control link 7 and the guide frame 3. Locking means
Reference numeral 22 has substantially the same structure as that of the first embodiment.

In addition to the above, the pinion 26 can be changed so as to switch to the unlock position by pulling it upward.

In the first embodiment, design changes such as integrating the pinion 26 and the base shaft 31 so that they cannot rotate relative to each other, and forming the rack body 25 on the upper wall of the slide groove 9 of the guide frame 3 are also possible. .

In the illustrated example, it is assumed that the window 2 is a vertical sliding window. However, the present invention can be applied to a horizontal sliding window or a round window sliding device.

 The bracket 4 may be omitted.
