Description

  The present invention relates to a technique for obtaining a sufficient urging force to rotate a shoji in the closed position to the open side while ensuring smooth rotation of the shoji that opens and closes the opening of the window frame.

  Conventionally, a window frame having an opening, a shoji that is pivotally attached to the window frame via a connecting portion and closes or opens the opening of the window frame, and biases the shoji in the opening direction. A window device including a stay damper is known (see, for example, Patent Documents 1 and 2).

  The stay damper is configured to urge the rod-shaped rod to protrude outward by gas, oil, or a spring filled in the cylindrical cylinder. The stay damper is housed in a space formed between the shoji and the window frame housed in the opening of the window frame, the rear end of the cylinder is attached to either the shoji or the window frame, and the rod Is attached to either the shoji or the window frame to urge the shoji from the closed position to the open position.

  By the way, when the shoji is rotated to the open side around the connecting portion, it is desirable that the turning direction of the shoji coincides with the projecting direction in which the rod of the stay damper projects from the cylinder.

  However, in the window device as described above, since the angle formed by the rotation direction of the shoji in the closed position toward the opening side and the protruding direction of the rod of the stay damper is large, the force that the rod tries to protrude from the stay damper is large. (Stay damper output) is not effectively utilized as a biasing force that biases the shoji in the closed position to rotate to the open side (see “Stay Only” in FIG. 8).

  For this reason, the stay damper output is increased to obtain a sufficient urging force to rotate the shoji in the closed position to the open side.

JP 2000-314267 A (page 4, FIG. 1) JP 58-16429 A (1st page, FIG. 1)

  However, when the stay damper output is increased as described above, sufficient urging force is obtained to rotate the shoji in the closed position to the open side, while in a direction orthogonal to the pivoting direction of the shoji to the open side. The urging force of the sliding door also increases, and there is a problem that the sliding door is difficult to rotate smoothly because the sliding door is lifted and abuts against the window frame or an unreasonable force acts on the connecting portion between the sliding door and the window frame. .

  The present invention has been made in view of such problems, and the object of the present invention is to move the shoji at the closed position to the open side while ensuring smooth rotation of the shoji that opens and closes the opening of the window frame. The purpose is to obtain a sufficient urging force for rotation.

  A kick-out mechanism for a window device according to claim 1 made to solve the above problem is used in a window device that opens and closes an opening of a window frame by rotating a shoji to close the opening. In the kick-out mechanism for the window device that kicks out the shoji from the position toward the open position, the rod is in a bar shape, both ends are bent from the base, and the shoji is in the closed position While the base is twisted, one end is engaged with the window frame and the other end is engaged with the shoji to bias the shoji from the closed position toward the open position. It features a torsion bar that exerts its power.

  According to the kick-out mechanism for the window device of the present invention configured as described above, the torsion bar of the kick-out mechanism is engaged with the window frame while the base is twisted when the shoji is in the closed position. When the other end is engaged with the shoji, the shoji is exerted to urge the shoji from the closed position to the open position (see “stay + torsion bar” in FIG. 8). Even without increasing the output of the damper, the shoji can be kicked to the open side by the action of the torsion bar of the kicking mechanism. Further, since it is not necessary to increase the output of the stay damper, the force for lifting the shoji unlike the conventional configuration does not occur, and the smooth rotation of the shoji can be ensured.

Therefore, it is possible to obtain a sufficient biasing force to rotate the shoji in the closed position to the open side while ensuring smooth turning of the shoji that opens and closes the opening of the window frame.
Further, according to the window device of the present invention, as described above, it is not necessary to increase the output of the stay damper, and smooth rotation of the shoji can be secured, so that the shoji is rotated from the open position to the closed position. Requires less force. For example, when the wire connected to the shoji is wound around the take-up drum and the shoji is rotated from the open position to the closed position, the operating force of the handle for rotating the take-up drum is light.

  Further, according to the window device of the present invention, since the torsion bar is adopted as the biasing means of the kicking mechanism, the kicking mechanism is compared with the case where another structure such as a coil spring is adopted as the biasing means. Space can be saved.

  The window device kick-out mechanism according to claim 2 is the window device kick-out mechanism according to claim 1, wherein the torsion bar is a rotation shaft when the bar-shaped base portion rotates the shoji. The tip of the other end is engaged with the shoji, and is rotatably attached to the shoji in a posture in parallel with the shoji.

According to the kick-out mechanism for a window device of the present invention configured as described above, the kick-out mechanism can be reduced in size while securing a sufficient urging force.
A kicking mechanism for a window device according to a third aspect is the kicking mechanism for a window device according to the second claim, wherein the tip of the one end of the torsion bar is placed on the inner wall surface of the window frame. A guide portion for locking and guiding in the longitudinal direction is formed.

According to the kick-out mechanism for the window device of the present invention configured as described above, the urging force by the kick-out mechanism can be effectively applied to the shoji that rotates to the open side.
The present invention includes a window frame having an opening, a shoji that is rotatably attached to the window frame via a connecting portion, and closes or opens the opening of the window frame, and the shoji in the opening direction. The present invention can also be applied to a window device that includes a stay damper that is biased.

  Specifically, a kick-out mechanism for a window device according to claim 4 includes a window frame having an opening, and a closed position that is rotatably attached to the window frame and closes the opening of the window frame. And a shoji that can change its posture between the opening position for opening the opening and a rod-shaped rod that is inserted into a cylindrical cylinder and biased to protrude outwardly, Either one of the rear end of the cylinder or the tip of the rod is rotatably attached to the shoji and the other is rotatably attached to the window frame, and the shoji is directed from the closed position to the open position.

Although it is fixed with screws, the illustration thereof is omitted here.

  The right frame member 14 of the window frame 10 is formed with a guide portion 17 that locks the end portion 41a of the torsion bar 41 of the torsion bar unit 40 and guides it in the vertical direction. The guide portion 17 is a step formed so that the closing side is one step higher than the opening side, and the right side of the inner wall surface of the right frame member 14 is positioned at a position where the end portion 41a of the torsion bar 41 abuts when the shoji 20 is closed. It is formed along the longitudinal direction of the frame member 14. In addition, although the guide part similar to the right frame member 14 of the window frame 10 is formed also in the left frame member 13 of the window frame 10, the illustration is abbreviate | omitted here.

[1.2. Description of configuration of shoji 20]
As shown in FIG. 1, similarly to the window frame 10, the shoji 20 includes an upper eaves 21 and a lower eaves 22 (not shown in FIG. 1, see FIG. 2), a left eave 23, and a right eave, which are extruded materials made of aluminum. The glass plate 25 is included in the interior in which 24 is connected to the four-sided frame. The shoji 20 is attached to a space (opening) formed inside the window frame 10. Specifically, as shown in FIG. 2, a hinge 22 a formed at the lower portion of the lower heel 22 is attached to the hinge 12 a of the lower frame member 12 of the window frame 10, and the shoji 20 is centered on the lower heel 22. As shown in FIG. 3 (b). As a result, the shoji 20 closes the opening of the window frame 10 (closed position, see FIG. 3B) and moves from the closed position to the open side to open the opening of the window frame 10. The posture can be changed between (open position, see FIG. 2).

  A space is formed between the right frame member 14 of the window frame 10 and the starboard 24 of the shoji 20 in the closed position, and the right stay damper 30 and the torsion bar unit 40 are accommodated in this space ( (See FIG. 2). The same applies to the left side.

  Further, as shown in FIG. 2, a bracket 26 for rotatably attaching the rear end portion 31a of the cylinder 31 of the left stay damper 30 is fixed by a screw 27 near the upper end of the port 23 of the shoji 20. ing. In addition, the starboard 24 of the shoji 20 has a bracket for fixing the rear end portion 31a of the cylinder 31 of the right stay damper 30 so as to be rotatable, as with the starboard 23 of the shoji 20. The illustration is omitted here.

[1.3. Description of the structure of the stay damper 30]
Next, the structure of the stay damper 30 will be described. 2 and 3, the rear end 31 a of the cylinder 31 of the stay damper 30 is attached to the port 23 of the shoji 20, and the rod 32 of the stay damper 30 is attached to the right frame member 14 of the window frame 10. Only the state where the distal end portion 32a is attached is shown.

  The stay damper 30 has a configuration in which a rod-shaped rod 32 is urged outwardly by gas, oil, or a spring filled in a cylindrical cylinder 31. In the stay damper 30, the rear end portion 31 a of the cylinder 31 is rotatably attached to the bracket 26 of the port 23 (or starboard 24) of the shoji 20, and the tip 32 a of the rod 32 is the left frame of the window frame 10. A posture in which the rear end portion 31a of the cylinder 31 is inclined more to the open side than the front end portion 32a of the rod 32 when the shoji 20 is in the closed position, and is rotatably attached to the bracket 15 of the member 13 (or the right frame member 14). Thus, the shoji 20 is urged from the closed position toward the open position.

[1.4. Description of the configuration of the torsion bar unit 40]
Next, the configuration of the left torsion bar unit 40 will be described. The right torsion bar unit 40 is configured to be bilaterally symmetric with the left torsion bar unit 40, and a detailed description thereof will be omitted here. Hereinafter, the left torsion bar unit 40 is simply referred to as a torsion bar unit 40.

The torsion bar unit 40 includes a torsion bar 41 and a bracket 42.
The torsion bar 41 is a spring steel rod-like member, and has both ends 41a and 41b bent in the same direction at substantially right angles from the rod-like base portion 41c.

  Detailed settings such as the length dimension of each part of the torsion bar 41 are as follows. First, the length of the base 41c is less than half of the length in the longitudinal direction of the upper arm 21 of the shoji 20 and is routed to the pulley 50 and the pulley 50 attached to the upper arm 21 of the shoji 20. It is set not to interfere with the wire 51 or the like. Further, the length of the end 41a is set to be smaller than the length in the vertical direction of the left and right inner wall surfaces of the shoji 20 and not to interfere with the stay damper 30 when the shoji 20 is rotated. Further, the length dimension of the end portion 41b is set smaller than the width dimension of the upper collar 21 of the shoji 20. Further, regarding the bending direction of the end portion 41a and the bending direction of the end portion 41b, the end of the end portion 41a is in contact with the guide portion 17 of the left frame member 13 of the window frame 10 when the shoji 20 is rotated. The portion 41a is inclined downward with respect to the normal line of the guide portion 17, and the end portion 41b is set along the upper surface of the upper collar 21 of the shoji 20 (see FIG. 3A). . Further, as described above, the tip of the end portion 41a that contacts the guide portion 17 has an R shape.

  The bracket 42 is a metal plate, and is formed with a cylindrical portion 42 a that can include the base portion 41 c of the torsion bar 41 and a cylindrical portion 42 b that can include the end portion 41 b of the torsion bar 41. The bracket 42 is configured such that the base portion 41c of the torsion bar 41 is included in the cylindrical portion 42a and the end portion 41b of the torsion bar 41 is included in the cylindrical portion 42b. 21 is attached to the upper left surface.

  In the torsion bar unit 40 configured in this way, when the shoji 20 is in the closed position, the end of the end 41a is engaged with the guide portion 17 of the left frame member 13 of the window frame 10, and the end 41b is The base 41c is twisted by being engaged with the upper collar 21 of the shoji 20 by the bracket 42, and exerts a biasing force that biases the shoji 20 from the closed position toward the open position.

The torsion bar unit 40 and the guide portion 17 of the left frame member 13 of the window frame 10 constitute a kick-out mechanism that kicks out the shoji 20 in the closed position to the open side.
[1.5. Description of other configurations]
A winding mechanism is used to rotate the shoji 20 in the open position to the closed position. This type of winding mechanism is configured such that a wire 51 hung on a pulley 50 attached to each of the upper part of the shoji 20 and the upper part of the window frame 10 can be wound on a winding drum arranged on the window frame 10 side. Is done. The configuration of the winding mechanism is in accordance with a known technique, and thus detailed description thereof is omitted here.

  A lock mechanism is used to lock the shoji 20 in the closed position. This type of locking mechanism is in the closed position and the state in which the claw member protrudes in front of the shoji 20 in the closed position to lock the shoji 20 in the closed position and is not allowed to rotate to the open side. The claw member is retracted from the front of the shoji 20 and is configured to be switchable between a state in which the shoji 20 in the closed position is not locked and the rotation to the open side is permitted. Since the configuration of the lock mechanism is in accordance with a known technique, a detailed description thereof is omitted here.

[2. Explanation of the operation of the outside window 1]
Next, the operation of the overturn window 1 will be described.
When the shoji 20 illustrated in FIGS. 1 and 2 is in the open position, when the wire 51 hung on the pulley 50 is wound around a take-up drum (not shown), the shoji 20 is moved from the open position to the closed position (FIG. 3). (See (b)), the stay damper 30 attached between the shoji 20 and the window frame 10 is compressed.

In the middle, the tip of the end portion 41a of the torsion bar 41 comes into contact with the guide portion 17 of the right frame member 14 of the window frame 10 (see FIG. 3A).
When the shoji 20 further approaches the closed position, the distal end of the end portion 41a of the torsion bar 41 moves downward while being guided by the guide portion 17 of the right frame member 14, and accordingly, the base portion 41c of the torsion bar 41 gradually moves. I will be twisted.

  When the shoji 20 is in the closed position (see FIG. 3A), the nail member of the lock mechanism is protruded in front of the shoji 20 in the closed position to lock the shoji 20 in the closed position to the open side. It is set as the state which does not permit rotation (rotation non-permission state).

At this time, the base portion 41c of the twisted torsion bar 41 exhibits a biasing force that biases the shoji 20 from the closed position toward the open position.
In order to rotate the shoji 20 to the open side, a claw member of a lock mechanism (not shown) is retracted from the front of the shoji 20 in the closed position. Then, the shoji 20 in the closed position is kicked out to the open side by the urging force by the base portion 41c of the twisted torsion bar 41 and starts to rotate. The urging force by the base 41c of the torsion bar 41 decreases as the twist of the base 41c is eliminated, but the urging force by the stay damper 30 increases as the pivot angle of the shoji 20 toward the open side increases. The shoji 20 turns to the open position (see FIG. 2).

[3. Effects of the embodiment]
(1) As described above, according to the outside turn window 1 of the present embodiment, when the left side torsion bar unit 40 constituting the kicking mechanism is in the closed position, the tip of the end portion 41a is the window frame. 10 is engaged with the guide portion 17 of the left frame member 13 and the end portion 41b is engaged with the upper collar 21 of the shoji 20 by the bracket 42, whereby the base portion 41c is twisted to release the shoji 20 from the closed position. The urging force that urges toward the position is exerted (see “stay + torsion bar” in FIG. 8). The same applies to the right torsion bar unit 40.

  Accordingly, the shoji 20 can be kicked to the open side by the action of the torsion bar unit 40 constituting the kicking mechanism without increasing the output of the stay damper 30. In addition, since the output of the stay damper 30 does not need to be increased, the force for lifting the shoji 20 as in the conventional configuration does not occur, and the smooth rotation of the shoji 20 can be ensured.

Therefore, sufficient urging force can be obtained to kick out the shoji 20 in the closed position toward the open side while ensuring smooth rotation of the shoji 20.
(2) Moreover, according to the external fall window 1 of this embodiment, since the output of the stay damper 30 does not need to be enlarged as mentioned above and the smooth rotation of the shoji 20 can be ensured, the shoji 20 can be secured. The force required to rotate from the open position to the closed position can be small. For example, when the wire 51 connected to the shoji 20 is wound around the take-up drum of the take-up mechanism and the shoji 20 is rotated from the open position to the closed position, the operation force of the handle for rotating the take-up drum is light. It ’s done.

  (3) Further, according to the outwardly tilting window 1 of the present embodiment, the torsion bar 41 is employed as the urging means included in the kicking mechanism, and therefore, when another configuration such as a coil spring is employed as the urging means. Compared to the above, it is possible to save the space of the kick-out mechanism.

[4. Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

(1) In the above embodiment, the present invention is applied to the window 1 by turning it over. However, the present invention is not limited to this, and the present invention is applicable to any window device that opens and closes the opening of the window frame by rotating the shoji. Applicable.
(1-1) For example, as illustrated in FIG. 4, the present invention may be applied to the protruding window 101 that can rotate the shoji 120 around the upper end portion of the window frame 110. In this case, the above-described torsion bar unit 40 is attached to the lower end of the shoji 120 unlike the case of the outside-turning window 1.

  (1-2) Further, as illustrated in FIG. 5, the present invention may be applied to an inward-turning window 201 in which the shoji 220 can be rotated indoors around the lower end portion of the window frame 210. In this case, the torsion bar unit 40 described above is attached to the upper end of the shoji 220 in the same manner as the case of the external fall window 1.

(1-3) Although not shown, the present invention may be applied to a window device in which a shoji can be rotated about one of the left and right end portions of the window frame.
(2) Moreover, in the said embodiment, although the torsion bar unit 40 is attached to the shoji 20, it is not restricted to this, You may attach the torsion bar unit 140 to the window frame 10 so that it may illustrate in FIG. . Specifically, the torsion bar 41 is attached to the lower surface of the upper frame member 11 of the window frame 10 using the bracket 142. In this case, the port side 23 (right side 24) of the shoji 20 functions as a guide portion that locks the end portion 41a of the torsion bar 41 and guides it in the vertical direction.

  (3) In the above embodiment, the torsion bar 41 is configured separately from the stay damper 30, but is not limited thereto, and the torsion bar 341 is integrated with the stay damper 330 as illustrated in FIG. 7. Also good.

  Specifically, the base 341c of the torsion bar 341 having a configuration in which one end 341a is bent from the base 341c is inserted into the locking hole 331b formed in the rear end 331a of the cylinder 331 of the stay damper 330. Thus, the torsion bar 341 is integrated with the stay damper 330. In this case, for example, the diameter dimension of the front side of the locking hole 331b is made larger than the diameter dimension of the base part 341c of the torsion bar 341, and the diameter dimension of the rear side of the locking hole 331b is set to the diameter of the base part 341c of the torsion bar 341. Make it smaller than the dimensions. If the base portion 341c is inserted to the back side of the locking hole 331b, the base portion 341c of the torsion bar 341 can be rotated on the front side of the locking hole 331b, and the back side of the locking hole 331b can be rotated. When the base 341c cannot rotate and the shoji 20 is in the closed position, the tip of the end 341a is engaged with the guide portion 17 of the window frame 10, and the tip of the base 341c is behind the locking hole 331b. The base part 341c is twisted by being engaged in the above-described manner, and exerts a biasing force that biases the shoji 20 from the closed position toward the open position.
