The window opening / closing device disclosed in Patent Document 1 rotates the take-up handle in the direction in which the operator winds the wire when closing the shoji (window body) in the open state. The operation of rotating the take-up handle requires the take-up handle to be rotated many times, which is troublesome for the operator and takes time and effort to close the open shoji. Also, if the take-up handle is installed at a position away from the window and it is difficult to know the open / closed state of the window while operating the take-up handle, it is difficult to know how far the take-up handle should be rotated to close the shoji. The rotation of the handle may be stopped during the complete closure, and the shoji may be left in an incomplete state.

An object of the present invention is that the window body can be smoothly swiveled from the closed state to the open state to easily open the window body without requiring time and effort, and the window body can be smoothly opened from the open state to the closed state. It is an object of the present invention to provide a window opening / closing system that can be swiveled to easily close a window body. Another object of the present invention is that the closed position of the window body can be clearly confirmed, the window body is not left in an incomplete state, and the window body is surely closed in a perfect state. It is to provide a window opening and closing system that can be used.

The premise of the present invention for solving the above-mentioned problems is that the free end is connected to the free end of the window body and the window body in which the free end rotates in the vertical direction around the rotating end rotatably installed in the window frame. The wire that swivels the window body from the closed state to the open state and swivels from the open state to the closed state, and the wire that swings in one direction to swivel the window body from the closed state to the open state, and the window body is in the open state. It is a window opening / closing system equipped with a wire actuating means for pulling a wire in the other direction in order to turn the wire into a closed state.

The feature of the present invention in the above premise is that a kicking means for applying a turning force to the window body at the time of initial movement for turning the window body from the closed state to the open state is installed in either the window frame or the window body. , The wire actuating means is located below the window frame and extends up and down, a slider that slides up and down along the guideline, and a slider that is connected to the slider and moves up and down with the up and down slide of the slider. The window opening / closing system consists of a traction member and a rotation mechanism that rotates with the vertical movement of the traction member to wind up the wire and unwind the wire. The wire is unwound in one direction while rotating the rotation mechanism, and the window body is swiveled from the closed state to the open state while applying a turning force to the window body by using the kicking force of the kicking means at the time of initial movement. Alternatively, the slider is slid in the vertical direction according to the guideline to operate the traction member in the vertical direction, and the wire is pulled in the other direction while rotating the rotation mechanism to rotate the window body from the open state to the closed state.

As an example of the present invention, in the window opening / closing system, the slider is slid upward in the vertical direction from the lower end of the guideline to operate the traction member in the vertical direction upward, and the wire is unwound in one direction while rotating the rotation mechanism, and kicks at the initial movement.

The wire is pulled in the other direction while rotating the rotation mechanism to rotate the window body from the open state to the closed state.

As another example of the present invention, the kicking means is a kicking spring that applies a turning force to the window body at the time of initial movement in which the free end portion of the window body turns from the closed position to the open position, and the window frame moves up and down. It is formed of an upper frame and a lower frame that are separated from each other in the direction and extend laterally, and a first and second side frames that are separated from each other in the lateral direction and extend in the vertical direction, and the window body can rotate to the lower frame. A rotating end that is installed in the closed position and is in close contact with the lower frame in a closed state, and a free end that is swiveled in a closed position that is in close contact with the upper frame in the closing operation and is swiveled in the lower open position in the vertical direction in the opening operation. A pair of kick-out springs are installed on the first and second side frames or the first and second side portions. In the window opening / closing system, when the free end of the window body turns from the closed position to the open position, a turning force is applied by the repulsive force of the kicking springs to turn, and the window is turned in the turning process except for the initial movement. Due to the weight of the main body, the free end of the window body automatically turns downward in the vertical direction, and before the free end of the window body turns to the closed position, the free end resists the repulsive force of those kicking springs. Turn upward in the vertical direction.

As another example of the present invention, the traction member is a traction chain whose one end is connected to the slider and moves up and down with the vertical slide of the slider, and a rotation mechanism is rotatably installed on the window frame. A rod extending laterally and a sprocket formed on one of the rods to engage with the traction chain and rotating with the vertical movement of the traction chain, and a sprocket formed on the other side of the rod to connect the wires to rotate the sprocket. It is formed of a roller that unwinds and winds up the wire.

As another example of the present invention, when the rotation mechanism is installed on the other side of the rod and twisted in the winding direction or in the direction opposite to the winding direction, a torsion spring that generates torque in the opposite direction proportional to the twisted angle is provided. Including, the window opening / closing system twists the torsion spring in the winding direction or in the direction opposite to the winding direction when the rod rotates in the direction of unwinding the wire, and the torsion spring exerts torque in the direction of pulling the wire, and the torque of the torsion spring. Helps wind the wire around the rollers.

As another example of the present invention, the window opening / closing system includes an erection unit extending downward from either the first side frame or the second side frame forming the window frame, and the guideline is erected. It is formed in the unit and is located below the window frame and extends in the vertical direction.

A first chain accommodating space formed from the above and accommodating the tow chain so as to be vertically movable is formed on the side of the first guide plate and extends in the vertical direction, and a second chain accommodating the tow chain so as to be vertically movable. A chain accommodation space is formed on the side of the second guide plate and extends in the vertical direction.

As another example of the present invention, the wire actuating means locks the slider slide while applying tension to the traction chain when the slider is slid up and down and the slider is located at the lower end of the guideline. Including the mechanism.

As another example of the present invention, a locking mechanism is rotatably installed at the lower end of the slider and an engaging cam formed at the lower end of the guideline, and an engaging pin is attached to a rotating base end located at the lower end of the slider. The engagement pin is formed from a swivel lever that moves around the outer periphery of the engagement cam, and the window open / close system moves the slider to the lower end of the guideline and then rotates the swivel lever in either forward or reverse direction. By moving the engagement pin to a predetermined lock position along the outer peripheral edge of the engagement cam, the slider slide is locked with tension applied to the traction chain, and the slider slide is locked. The slider can be slid by rotating the swivel lever in either the forward or reverse direction and moving the engaging pin to a predetermined unlocked position along the outer peripheral edge of the engaging cam.

By adjusting the installation position, the sliding distance of the slider in the vertical direction from the lower end of the guideline can be adjusted, and the turning angle downward from the upper frame of the free end of the window body can be adjusted.

As another example of the present invention, the window opening / closing system includes a fixing means installed on the slider to fix the slider at a predetermined position in the guideline, and the window opening / closing system is in the process of sliding the slider up and down in the guideline. The slider can be fixed at a predetermined position in the guideline by using the fixing means, and the window body can be opened with the free end of the window body swiveled downward from the upper frame at an arbitrary angle.

According to the window opening / closing system according to the present invention, the slider is slid in the vertical direction according to the guideline to operate the traction member in the vertical direction to rotate the rotation mechanism while feeding the wire in one direction, and kicking the kicking means at the time of initial movement. Since the window body is swiveled from the closed state to the open state while applying a turning force to the window body by using the ejection force, the window body can be swiveled from the closed state to the open state only by sliding the slider in the vertical direction. The window body can be easily opened by smoothly turning the window body from the closed state to the open state without requiring time and effort. In the window opening / closing system, the slider is slid up and down according to the guideline to operate the traction member in the up and down direction, and while rotating the rotation mechanism, the wire is pulled in the other direction to turn the window body from the open state to the closed state. The window body can be swiveled from the open state to the closed state simply by sliding the slider up and down, and the window body can be smoothly swiveled from the open state to the closed state without any time and effort. Can be easily closed. Since the window opening / closing system applies a turning force to the window body by using the kicking force of the kicking means at the time of initial movement, when the slider is slid up and down, the window body is pushed by the kicking force of the kicking means. It can be turned reliably and the window body can be reliably opened. In the window opening / closing system, when closing the opened window body, it is not necessary to rotate the take-up handle many times as in the conventional technique, and the slider can be slid up and down, and the window body in the open state can be closed. Can be closed in a short time with a simple slide operation.

The slider is slid upward in the vertical direction from the lower end of the guideline to operate the traction member upward in the vertical direction, and the wire is unwound in one direction while rotating the rotation mechanism. While applying a turning force to the main body, the window main body is swiveled from the closed state to the open state, the slider is slid downward in the vertical direction from the upper end of the guideline to operate the traction member downward in the vertical direction, and the wire while rotating the rotation mechanism. The window opening / closing system that turns the window body from the open state to the closed state by pulling it in the other direction can turn the window body from the closed state to the open state just by sliding the slider up and down in the vertical direction, which is troublesome. In a short time, the window body can be smoothly swiveled from the closed state to the open state to easily open the window body, and the window body can be opened from the open state simply by sliding the slider up and down. The window body can be swiveled to the closed state, and the window body can be smoothly swiveled from the open state to the closed state without any labor and time, and the window body can be easily closed. In the window opening / closing system, when closing the opened window body, it is not necessary to rotate the take-up handle many times as in the conventional technique, and the slider can be slid up and down in the open state. The main body can be closed in a short time with a simple slide operation.

The kicking means is a kicking spring that applies a turning force to the window body at the time of initial movement to turn the free end of the window body from the closed position to the open position, and the window frame is the upper frame, the lower frame, and the first and second sides. A pair of rotating ends formed from a square frame and the window body rotatably installed on the lower frame, a free end portion that swivels in an open position in the vertical direction and a second side portion, and a pair of first and second side portions. Kick-out springs are installed on the first and second side frames of the window frame or the first and second side parts of the window body, and they are kicked out when the free end of the window body turns from the closed position to the open position. While turning by applying a turning force by the repulsive force of the spring, the free end of the window body automatically turns downward in the vertical direction due to the weight of the window body in the turning process except at the time of initial movement, and the free end of the window body The window opening / closing system, in which the free end of the window turns upward in the vertical direction against the repulsive force of those kicking springs before turning to the closed position, is the initial movement in which the free end of the window body turns from the closed position to the open position. Sometimes, while turning using the repulsive force of those kicking springs, the free end of the window body automatically turns downward in the vertical direction due to the weight of the window body in the turning process except during the initial movement. By using the repulsive force and the weight of the window body, the window body can be reliably swiveled when the slider is slid up and down (up and down), and the slider can be turned up and down (up and down). By the slide operation, the window body can be smoothly swiveled from the closed state to the open state without taking time and effort, and the window body can be easily opened. In the window opening / closing system, the free end of the window body automatically turns vertically and downward due to the weight of the window body during the turning process except for the initial movement, so that the window body does not require a slider slide operation in an emergency. Can be released at once. In the window opening / closing system, before the free end of the window body turns to the closed position, the free end turns upward in the vertical direction against the repulsive force of those kicking springs, so that when the window body is opened again. At the time of initial movement, the repulsive force of those kicking springs can be used again to smoothly open the window body.

The traction member is a traction chain in which one end is connected to the slider and moves up and down with the vertical slide of the slider, and the rotation mechanism is rotatably installed on the window frame.

In the window opening / closing system, the slider is slid vertically (downward in the vertical direction) from the upper end of the guideline to operate the traction chain in the vertical direction (downward in the vertical direction), and the traction chain is operated in the vertical direction (downward in the vertical direction). Since the sprocket is rotated to wind the wire around the roller and the window body is swiveled from the open state to the closed state, the window body is swiveled from the open state to the closed state simply by sliding the slider in the vertical direction (downward in the vertical direction). The window body can be smoothly swiveled from the open state to the closed state and the window body can be easily closed without requiring time and effort.

The rotation mechanism contains a torsion spring that produces torque in the opposite direction proportional to the twisted angle, and when the rod rotates in the direction of unwinding the wire, the torsion spring twists in the winding direction or in the direction opposite to the winding direction, and the torsion spring The window opening / closing system, which produces torque in the direction of pulling the wire (winding direction) and encourages the winding of the wire to the rollers by the torque of the torsion spring, is used to close the window body in the open state. Force is required to slide the slider vertically and downward due to its own weight, but the torque of the torsion spring promotes the winding of the wire around the roller, so by using the torsion spring, a large force is not required. The slider can be slid downward in the vertical direction, and the window body can be smoothly swiveled from the open state to the closed state to easily close the window body.

A guideline is formed on the erection unit, which includes an erection unit extending downward from either the first side frame or the second side frame forming the window frame, and is located below the window frame in the vertical direction.

The size of the outer diameter of the sprocket 83 can be adjusted. By increasing the outer diameter of the sprocket 83 under the condition that the peripheral speed of the sprocket 83 (speed of the slider 20) is the same, the ratio of the diameter of the sprocket 83 to the diameters of the first and second rods 82a and 82b is large. Therefore, the force (force to push the slider downward) when turning the window bodies 13a and 13b upward from the open state to the closed state is small, while the window bodies 13a and 13b are closed from the open state. Since the total rotation speeds of the first and second rods 82a and 82b required for the sprocket 83 do not change, the vertical movement dimension of the slider 20 becomes longer as the outer diameter of the sprocket 83 is increased. On the contrary, by reducing the outer diameter of the sprocket 83, the ratio of the diameter of the sprocket 83 to the diameters of the first and second rods 82a and 82b becomes smaller, and the window bodies 13a and 13b are changed from the open state to the closed state. The force for turning the slider upward in the vertical direction (the force for pushing the slider downward) increases, but the moving dimension of the slider 20 in the vertical direction becomes shorter.

In the window opening / closing system 10, by increasing the outer diameter of the sprocket 83, the vertical movement dimension of the slider 20 between the closed state and the open state of the first and second window bodies 13a and 13b increases. The slider 20 can be slid up and down in the vertical direction and downward in the vertical direction without requiring a large force, and the window bodies 13a and 13b can be easily swiveled from the closed state to the open state, and the window bodies 13a, The 13b can be easily swiveled from the open state to the closed state.

The window opening / closing system 10 requires a force when sliding the slider 20 vertically upward or vertically downward by reducing the outer diameter of the sprocket 83, but the first and second window bodies 13a and 13b are in the closed state. The vertical movement dimension (slide distance) of the slider 20 between the closed state and the open state can be reduced, and the window bodies 13a and 13b can be swiveled from the closed state to the open state simply by sliding the slider 20 for a short distance. At the same time, the window bodies 13a and 13b can be swiveled from the open state to the closed state.

The first and second rollers 84a and 84b are made of synthetic resin or a metal such as aluminum, stainless steel, or other alloy, and are formed into a cylindrical shape.

The second roller 84b is accommodated in the second accommodating space 60b of the second drive unit 17b, and is installed (fitted) in the intermediate portion of the second rod 82b.

The first roller 84a rotates in a clockwise direction (forward direction) or a counterclockwise direction (counterclockwise direction) with the rotation of the first rod 82a, and the second roller 84b rotates with the rotation of the second rod 82b. Rotate clockwise (forward) or counterclockwise (counterclockwise). The other end of the first wire 15a is connected and fixed to the first roller 84a, and the other end of the second wire 15b is connected and fixed to the second roller 84b.

When the sprocket 83 is viewed from the other end side of the first rod 82a, the first roller 84a rotates in the counterclockwise direction, so that the first wire 15a is attached to the first roller 84a as shown in FIG. Is picked up in the other direction (front-back direction and rear). By rotating the first roller 84b in the clockwise direction, as shown in FIG. 10, the first wire 15a is unwound from the first roller 84b in one direction (forward in the front-rear direction). When the sprocket 83 is viewed from the other end side of the second rod 82b, the second roller 84b rotates in the clockwise direction, so that the second wire 15b is attached to the second roller 84b in the other direction (rearward in the front-rear direction). Will be taken over. As the second roller 84b rotates in the counterclockwise direction, the second wire 15b is fed from the second roller 84b in one direction (forward in the front-rear direction).

The first and second ring mounting drums 85a and 85b are made of synthetic resin or metal such as aluminum, stainless steel, and other alloys, and are formed into a cylindrical shape. The first ring mounting drum 85a is accommodated in the first accommodating space of the first drive unit 17a, and is installed (fitted) on the side of one end of the first rod 82a (laterally outward of the first roller 84a). It is). The second ring mounting drum 85b is accommodated in the second accommodating space 60b of the second drive unit 17b, and is installed (fitted) on the side of one end of the second rod 82b (laterally outward of the second roller 84b). It is).

The first ring mounting drum 86a is installed (fitted) in the middle portion of the first rod 82a according to the size and shape of the window bodies 13a and 13b, and the first roller 84a is on the side of one end of the first rod 82a. It may be installed (may be fitted) at (laterally outward of the first ring mounting drum 86a). The second ring mounting drum 86b is installed (fitted) in the middle portion of the second rod 82b, and the second roller 84b is located on the side of one end of the second rod 82b (laterally outward of the second ring mounting drum 86b). It may be installed (may be fitted).

The first and second torsion springs 86a and 86b are made of hard steel wire, stainless steel wire, and phosphor bronze for springs. The first torsion spring 86a is attached to the first ring mounting drum 85a and extends in the axial direction of the first rod 82a. The second torsion spring 86b is attached to the second ring mounting drum 85b and extends in the axial direction of the second rod 82b. As the arm shape of the torsion springs 86a and 86b, short hooks, straights, one-step bending and the like can be used. The outer diameter, inner diameter, and number of turns of the torsion springs 86a and 86b are the torque required for turning the first and second window bodies 13a and 13b (shoji) in the vertical direction and downward (sliding the slider 20 in the vertical direction and downward). It can be set arbitrarily depending on the auxiliary force required for.

In the first rotation mechanism 23a, with the first ring mounting drum 85a inserted through the first torsion spring 86a, the fixed point of the arm of the first torsion spring 86a is the first plate to the third plate of the first drive unit 17a. It is connected / fixed to any of 56 to 58 and the bearing plate 59, and the load point of the arm of the first torsion spring 86a is connected / fixed to the outer peripheral edge of the first rod 82a.

In the second rotation mechanism 23b, with the second ring mounting drum 85b inserted through the second torsion spring 86b, the fixed point of the arm of the second torsion spring 86b is the first plate to the third plate of the second drive unit 17b. It is connected / fixed to any of 56 to 58 and the bearing plate 59, and the load point of the arm of the second torsion spring 86b is connected (fixed) to the outer peripheral edge of the second rod 82b.

In the first and second torsion springs 86a and 86b, the first and second rods 82a and 82b rotate clockwise, and the first and second wires 15a and 15b are one from the first and second rollers 84a and 84b. When it is fed in the direction (forward and backward), it twists in the winding direction or in the direction opposite to the winding direction. When the first and second torsion springs 86a and 86b are twisted in the direction opposite to the winding direction, they generate torque (repulsive force) in the opposite direction (winding direction) proportional to the twisted angle and twist in the winding direction. In this case, torque (repulsive force) is generated in the opposite direction (opposite to the winding direction) proportional to the twisted angle. In the window opening / closing system 10, the first and second torsion springs 86a and 86b are such that the load acting on the slider 20 when the window bodies 13a and 13b are swiveled from the lower side to the upper side in the vertical direction is about 1.5 to 2 kg. Torque (repulsive force) is adjusted.

FIG. 11 is a partially enlarged side view of the window opening / closing system 10 in a state where the window bodies 13a and 13b are closed, and FIG. 12 is a partially enlarged side view of the window opening / closing system 10 similar to FIG. 11 shown in a cross section. FIG. 13 is a partially enlarged side view of the window opening / closing system 10 in a state where the window bodies 13a and 13b are open, and FIG. 14 is a partially enlarged side view of the window opening / closing system 10 similar to FIG. 13 shown in a cross section. In FIGS. 12 and 14, the tow chain 22 (traction member) is shown in an exposed state.

An example of a procedure for opening the window bodies 13a and 13b by turning the free end portions 37 of the window bodies 13a and 13b vertically downward from the state where the first and second window bodies 13a and 13b are closed is as follows. That's right. The window opening / closing system 10 is manually operated by a person entering and exiting the building in which it is installed. In the state where the first and second window main bodies 13a and 13b are closed, the first and second wires 15a and 15b are taken in the other direction (rearward in the front-rear direction) by the first and second rollers 84a and 84b (rearward in the front-rear direction). The free ends 37 of the window bodies 13a and 13b are swiveled to the closed position, the rotating end 36 is in close contact with the lower frame 25, and the first and second side portions 38a and 38b are the first. And the second side frames 26a and 26b are in close contact with each other, and the free end portion 37 is in close contact with the upper frame 24.

Further, the slider 20 is located at the lower end 63 of the guideline 19, and the engaging pin 79 of the swivel lever 73 slides (overcomes) the outer peripheral edge 75 of the engaging cam 72 in one direction, and the engaging pin 79 is in the locked position. The slide (up and down movement) of the slider 20 is locked in a state where tension is applied to the tow chain 22. When the slide of the slider 20 is locked, as shown in FIG. 7, the swivel lever 73 hangs down from the lower end 63 of the guideline 19 in the vertical direction.

First, while gripping the grip portion 77 (handle) of the swivel lever 73, while pushing (pushing down) the swivel lever 73 vertically and downward, the grip portion 77 of the swivel lever 73 is pressed in the counterclockwise direction (reverse direction). ) Is applied with a turning force. By applying a turning force to the grip portion 77, the swivel arm 78 and the engaging pin 79 swivel in the counterclockwise direction (reverse direction), while the engaging pin 79 moves the outer peripheral edge 75 of the engaging cam 72 in the other direction. Sliding (overcoming), the engagement pin 79 moves to the unlocked position, and the engagement between the engagement pin 79 and the engagement cam 72 is released. When the engaging pin 79 is moved to the unlocked position, the slide (vertical movement) of the slider 20 is unlocked and the tension acting on the tow chain 22 is released.

When the grip portion 77 of the swivel lever 73 is swiveled in the counterclockwise direction, the swivel arm 78 also swivels in the counterclockwise direction (counterclockwise direction), and as shown in FIG. 8, the tip 80 of the swivel arm 78 is erected. It abuts on the inner surface of the second erection plate 43 of the unit 16. When the tip 80 of the swivel arm 78 comes into contact with the inner surface of the second erection plate 43, the grip portion 77 (swivel lever 73) stops swiveling in the counterclockwise direction at that time.

The swivel lever 73 (grip portion 77) is unlocked by swiveling the swivel lever 73 (grip portion 77) in the counterclockwise direction (reverse direction) by 15 to 20 ° from the state of FIG. 7 hanging downward from the lower end 63 of the guideline 19. In addition, the extension dimension of the swivel arm 78 and the positional relationship between the engagement cam 72 and the engagement pin 79 are adjusted. Further, when the tip 80 of the swivel arm 78 is swiveled by 15 to 20 ° in the counterclockwise direction (counterclockwise direction), the swivel arm 78 extends so that the tip 80 of the swivel arm 78 abuts on the inner surface of the second erection plate 43 of the erection unit 16. The dimensions have been adjusted.

Next, with the grip portion 77 (handle) of the swivel lever 73 gripped, the slider 20 is slid (pushed up) vertically upward from the lower end 63 of the guideline 19 toward the upper end 61 together with the swivel lever 73. When the slider 20 is slid upward in the vertical direction, the traction chain 22 located in the first chain accommodating portion 46 operates upward in conjunction with the slide of the slider 20, and the sprocket 83 engaged with the traction chain 22 operates in the clockwise direction. Rotate to. When the sprocket 83 rotates, the first and second rods 82a and 82b (rotating mechanisms 23a and 23b) rotate clockwise in conjunction with the rotation, and the first rod 82a and 82b rotate as the first and second rods 82a and 82b rotate. And the second rollers 84a and 84b rotate in the clockwise direction. When the first and second rollers 84a and 84b rotate in the clockwise direction, as shown in FIGS. 13 and 14, the first and second wires 15a and 15b are unidirectionally (front and back) from the first and second rollers 84a and 84b. Forward in the direction).

At the time of initial movement (at the start of turning) in which the first and second window bodies 13a and 13b are swiveled from the closed state to the open state, the first side portions 38a and the second side portions 38b of the window bodies 13a and 13b are installed. The repulsive force of the first and second kicking springs 14a and 14b (kicking means) acts on the free end portions 37 of the window main bodies 13a and 13b, and the repulsive force (kicking force) of the kicking springs 14a and 14b causes the first. The free end portions 37 of the first and second window bodies 13a and 13b are pressed (pushed out) forward in the front-rear direction, and the free end portions 37 of the window bodies 13a and 13b are subjected to a downward turning force in the vertical direction.

The first kick-out spring 14a (kick-out means) is installed on the first contact plate 32 of the first side frame 26a of the first and second window frames 12a and 12b, and the second kick-out spring 14b (kick-out) is installed. When the means) are installed on the second contact plate 34 of the second side frame 26b of the first and second window frames 12a and 12b, the repulsive force of the kicking springs 14a and 14b (kicking means) is the window. It acts on the free end portions 37 of the main bodies 13a and 13b, and the free end portions 37 of the first and second window main bodies 13a and 13b are pressed forward in the front-rear direction by the repulsive force (kicking force) of the kicking springs 14a and 14b. (Extruded), a turning force in the vertical direction and downward is applied to the free end portions 37 of the window bodies 13a and 13b.

The first and second window bodies 13a and 13b utilize the repulsive force of the first and second kick-out springs 14a and 14b when the free end portions 37 of the window bodies 13a and 13b turn from the closed position to the open position at the initial movement. In the turning process except at the time of initial movement, the free end portions 37 of the window main bodies 13a and 13b automatically turn downward in the vertical direction around the rotating end portions 36 due to the weight of the window main bodies 13a and 13b.

The free ends 37 of the first and second window bodies 13a and 13b automatically rotate downward in the vertical direction, so that the first and second wires 15a and 15b are automatically extended in one direction (front and rear). As a result, the first and second rods 82a and 82b (rotating mechanisms 23a and 23b) automatically rotate in the clockwise direction, and the sprocket 83 automatically rotates in the clockwise direction. Further, the tow chain 22 automatically operates upward and the slider 20 automatically slides upward toward the upper end 61 of the guideline 19.

When the first wire 14a is unwound from the first roller 84a in one direction (forward in the front-rear direction) and the first rod 82a (first ring mounting drum 85a) rotates in the clockwise direction, the first torsion spring 86a is an arm thereof. The load point of the arm is twisted in the direction opposite to the winding direction or twisted in the winding direction with the fixed point of the above as the twisting base end. When the second wire 14b is unwound from the second roller 84b in one direction (forward in the front-rear direction) and the second rod 84b (second ring mounting drum 85b) rotates in the clockwise direction, the second torsion spring 86b is an arm thereof. The load point of the arm is twisted in the direction opposite to the winding direction or twisted in the winding direction with the fixed point of the above as the twisting base end.

When the first and second torsion springs 86a and 86b are twisted in the direction opposite to the winding direction or twisted in the winding direction, the torsion springs 86a and 86b are twisted in the opposite direction (winding direction or winding direction) proportional to the twisted angle. Is in the opposite direction), and the torque of the torsion springs 86a and 86b causes the free end portions 37 of the first and second window bodies 13a and 13b to swivel upward in the vertical direction from the open position to the closed position. Power is given.

The window opening / closing system 10 slides the slider 20 vertically upward from the lower end 63 of the guideline 19 toward the upper end 61 of the intermediate portion 62 (the central area in the vertical direction of the erection unit 16) to move the traction chain 22 (traction member) up and down. It is operated upward in the direction, and the sprocket 83 (rotating mechanism 23a, 23b) is rotated by the upward operation of the traction chain 22, and the first and second wires 15a, 15b are fed out from the first and second rollers 84a, 84b. Since the first and second window bodies 13a and 13b are swiveled from the closed state to the open state, the window bodies 13a and 13b can be swiveled from the closed state to the open state only by sliding the slider 20 in the vertical direction upward. It is possible to smoothly rotate the first and second window bodies 13a and 13b from the closed state to the open state and easily open the window bodies 13a and 13b without requiring time and effort.

In the window opening / closing system 10, the repulsion of the first and second kick-out springs 14a and 14b (kick-out means) is performed when the free end portions 37 of the first and second window bodies 13a and 13b turn from the closed position to the open position. This is because the free ends 37 of the window bodies 13a and 13b automatically turn downward in the vertical direction due to the weight of the window bodies 13a and 13b during the turning process except during the initial movement while turning using the force (feeding force). By utilizing the repulsive force of the first and second kick-out springs 14a and 14b, the window bodies 13a and 13b can be reliably swiveled at the time of the initial movement of the slider 20 to slide upward in the vertical direction. By sliding upward, the window bodies 13a and 13b can be smoothly swiveled from the closed state to the open state, and the window bodies 13a and 13b can be easily opened. In the window opening / closing system 10, the free end portions 37 of the window bodies 13a and 13b are rotated by the repulsive force (feeding force) of the first and second kicking springs 14a and 14b (kicking means) at the time of initial movement, and at the time of initial movement. In the turning process, the free ends 37 of the window bodies 13a and 13b automatically turn downward due to the weight of the first and second window bodies 13a and 13b, so that the slider 19 can be slid in an emergency. The window bodies 13a and 13b can be opened at once without the need.

The window opening / closing system 10 rotates the grip portion 77 (swivel lever 73) in the counterclockwise direction (either forward or reverse) with the slide of the slider 20 locked, and engages the engaging pin 79 with the engaging cam 72. Since the lock is released by moving the outer peripheral edge 75 to the sliding (overcoming) unlock position, the lock can be easily released from the locked state in which the slide of the slider 20 is locked. And the second window main bodies 13a and 13b can be easily opened.

The window opening / closing system 10 is unlocked by turning the grip portion 77 (swivel lever 73) by 15 to 20 ° from the state where the slide of the slider 20 is locked, so that the slide of the slider 20 is locked. The lock can be easily and quickly released without causing the grip portion 77 (swivel lever 73) to be largely swiveled (for example, swiveled by 90 °).

An example of a procedure for closing the window bodies 13a and 13b by turning the free end portions 37 of the window bodies 13a and 13b vertically upward from the state where the first and second window bodies 13a and 13b are open is as follows. That's right. While gripping the grip portion 77 (handle) of the swivel lever 73, the slider 20 is slid (pushed down) vertically and downward from the upper end 61 to the lower end 63 of the guideline 19 together with the swivel lever 73. Due to the torque (repulsive force) of the first and second torsion springs 86a and 86b, the load (kg) acting on the slider 20 when the window bodies 13a and 13b are swiveled from the lower side to the upper side in the vertical direction is 1.5 to. It is adjusted to about 2 kg.

When the slider 20 is slid downward, the traction chain 22 operates downward in the vertical direction in conjunction with the slide of the slider 20, and the sprocket 83 engaged with the traction chain 22 rotates in the counterclockwise direction. When the sprocket 83 rotates, the first and second rods 82a and 82b (rotating mechanisms 23a and 23b) rotate counterclockwise in conjunction with the rotation, and the first and second wires 15a and 15b are the first and second rods. It is wound around the rollers 85a and 84b in the other direction (rearward in the front-rear direction).

By winding the first and second wires 15a and 15b around the first and second rollers 84a and 84b, the free end portions 37 of the first and second window bodies 13a and 13b move from the open position to the closed position. Start turning upward in the vertical direction. Since the torque of the first and second torsion springs 86a and 86b gives the free end portions 37 of the first and second window bodies 13a and 13b a turning force to turn from the open position to the closed position, the slider 20 The entire weight of the window bodies 13a and 13b is not applied to the slide, and the load (range of 1.5 to 2 kg) obtained by subtracting the repulsive force of the torsion springs 86a and 86b from the weight of the window bodies 13a and 13b is applied to the slider 20. It works.

By sliding (pushing down) the slider 20 to the lower end 63 of the guideline 19, the first and second window bodies 13a and 13b turn from the open state to the closed state. When the first and second window main bodies 13a and 13b are closed, the twists of the first and second torsion springs 86a and 86b are returned, and the torque of the torsion springs 86a and 86b becomes zero. Before the free end portions 37 of the window bodies 13a and 13b turn to the closed position, the free end portions 37 are swiveled upward in the vertical direction against the repulsive force of the kicking springs 14a and 14b, and the kicking spring 14a The first and second window main bodies 13a and 13b are closed in a state where the repulsive force of 14b is applied to the free end portion 37. After sliding the slider 20 to the lower end 63 of the guideline 19, while gripping the grip portion 77 of the swivel lever 73, while pressing the swivel lever 73 vertically and downward (while pushing down), the grip portion 77 is clockwise. Apply a turning force in the (positive direction).

By applying a turning force to the grip portion 77 and turning the turning lever 73 clockwise (positive direction) by 15 to 20 °, the engaging pin 79 turns clockwise (positive direction) and the engaging pin. The 79 slides (overrides) the outer peripheral edge 75 of the engaging cam 72 in one direction, the engaging pin 79 moves to the locked position, and the engaging pin 79 and the engaging cam 72 engage with each other. When the engaging pin 79 is moved to the locked position, the swivel lever 73 hangs downward from the lower end 63 of the guideline 18, tension is applied to the tow chain 22, and the slide (up and down movement) of the slider 20 is locked. The engaging pin 79 moves to the locked position and tension is applied to the tow chain 22, so that the rotating end portion 36 is in close contact with the lower frame 25, and the first and second side portions 38a and 38b are the first. The free end portion 37 is in close contact with the upper frame 24 while being in close contact with the first and second side frames 26a and 26b.

The window opening / closing system 10 slides the slider 20 downward from the upper end 61 of the guideline 19 to operate the traction chain 22 (traction member) downward in the vertical direction, and the sprocket 83 (rotating mechanism 23a) is operated downward by the traction chain 22. , 23b) is rotated to wind the first and second wires 15a and 15b around the first and second rollers 84a and 84b, and the first and second window bodies 13a and 13b are swiveled from the open state to the closed state. The window bodies 13a and 13b can be swiveled from the open state to the closed state only by sliding the slider 20 downward in the vertical direction, which does not require time and effort, and the first and second window bodies 13a, The window bodies 13a and 13b can be easily closed by smoothly turning the 13b from the open state to the closed state. In the window opening / closing system 10, when closing the opened window bodies 13a and 13b, it is not necessary to rotate the take-up handle many times as in the prior art, and the slider 20 may be slid vertically and downwardly. The window bodies 13a and 13b in the open state can be closed in a short time by a simple slide operation.

The window opening / closing system 10 rotates the grip portion 77 of the swivel lever 73 in the clockwise direction (positive direction) at the lower end 63 of the guideline 19, and slides the engaging pin 79 of the swivel lever 69 on the outer peripheral edge 75 of the engaging cam 72. Since the slide (vertical movement) of the slider 20 is locked while moving to the moved (overcoming) lock position and applying tension to the tow chain 22, the engagement pin 79 is moved to the lock position to perform the first step. The closed positions of the second window bodies 13a and 13b can be clearly confirmed, and the window bodies 13a and 13b are not left in an incomplete state, and the window bodies 13a and 13b are in a perfect state. Can be closed securely and confidentially.

Since the window opening / closing system 10 locks the slide of the slider 20 in a state where tension is applied to the traction chain 22, the traction chain 22 does not loosen and the first and second window bodies 13a and 13b are airtightly closed. It is possible to prevent (block) the flow of air when the window bodies 13a and 13b are closed. Since the window opening / closing system 10 can lock the slide of the slider 20 by turning the grip portion 77 of the turning lever 73 by 15 to 20 ° from the state where the slider 20 is unlocked, the lock of the slider 20 is released. The slide of the slider 20 can be easily and quickly locked without causing the grip portion 77 of the swivel lever 73 to be swiveled (for example, swiveled by 90 °).

When closing the first and second window bodies 13a and 13b that are in the open state without using the first and second torsion springs 86a and 86b, the slider 20 is moved downward in the vertical direction by the weight of the window bodies 13a and 13b. Although a considerable force is required to slide the window opening / closing system 10, the torque of the torsion springs 86a and 86b causes the first and second wires 15a and 15b to be wound around the first and second rollers 84a and 84b. The torques of the torsion springs 86a and 86b are adjusted so that the load acting on the slider 20 when the window bodies 13a and 13b are swiveled upward from the lower part in the vertical direction is about 1.5 to 2 kg. Therefore, by using these torsion springs 86a and 86b, the slider 20 can be slid downward in the vertical direction without requiring a large force, and the first and second window main bodies 86a and 86b are closed from the open state. The window bodies 86a and 86b can be easily closed by swirling smoothly.

FIG. 15 is a side view of the erection unit 16 shown as another example, and FIG. 16 is a side view of the erection unit 16 shown in a state where the slider 20 is in contact with the stopper 87. FIG. 17 is a partially enlarged view of the erection unit 16 showing a state in which the slider 2-is fixed to a predetermined position of the guideline 19 by the set screw 88, and FIG. 18 is a cross-sectional view taken along the line AA of FIG. Is. The erection unit 16 shown in FIGS. 15 to 18 is different from that of FIG. 4, in that the stopper 87 is installed at a predetermined position in the guideline 19 of the erection unit 16, and the slider 20 has a set screw 88 (fixing means). It is in the point where it is installed.

Since the other configurations of the window opening / closing system 11 including the erection unit 16 of FIGS. 15 to 18 are the same as those of the window opening / closing system 10 of FIG. 1, the other configurations of the window opening / closing system 11 will be described in FIG. To be used. Since the configuration of the erection unit 16 is the same as that of FIG. 4, the description of the configuration of the erection unit 16 will be omitted by referring to the description of FIG. 4 and adding the same reference numerals as those of FIG.

A stopper 87 is detachably attached to the guideline 19 of the erection unit 16. The stopper 87 is installed at a predetermined position (base plate 44 or connection plate 55) in the intermediate portion 62 (moving space) of the guideline 19 by a predetermined connection means. The upper end of the upper plate 64 of the slider 20 that slides upward in the vertical direction abuts on the stopper 87. When the upper end of the upper plate 64 abuts on the stopper 87, the slider 20 stops sliding further upward.

The installation position in the intermediate portion 62 (moving space) of the guideline 19 of the stopper 87 can be arbitrarily determined. By adjusting the installation position of the stopper 87 in the intermediate portion 62 of the guideline 19, the vertical movement distance (slide distance) of the slider 20 in the guideline 19 can be adjusted, and the first and second window main bodies 13a and 13b can be adjusted. The vertical and downward turning angle (open area) of the can be adjusted.

When the slide (vertical movement) of the slider 20 is unlocked and the slider 20 is slid upward (pushed up) from the lower end 63 of the guideline 19 toward the upper end 61 together with the swivel lever 73, the first step and the swivel process are performed. Due to the weight of the second window bodies 13a and 13b, the free ends 37 of the window bodies 13a and 13b automatically rotate downward in the vertical direction around the rotating end 36, and the slider 20 moves toward the upper end 61 of the guideline 19. It automatically slides upward, but when the upper end of the upper plate 64 of the slider 20 abuts on the stopper 87, the slide in the guideline 19 of the slider 20 stops, and at that point, the traction chain 22 moves upward in the vertical direction. The operation is stopped, the rotation of the sprocket 83 in the clockwise direction is stopped, and the feeding of the first and second wires 15a and 15b in one direction (forward and backward) is stopped.

When the slider 20 comes into contact with the stopper 87 and the feeding of the wires 15a and 15b is stopped, the free end portions 37 of the first and second window bodies 13a and 13b stop turning downward in the vertical direction. The vertical and downward turning angles of the first and second window bodies 13a and 13b differ depending on the installation position in the intermediate portion 62 (moving space) of the guideline 19 of the stopper 87, and the open area when the window bodies 13a and 13b are opened. Is different.

The set screw 88 (fixing means) is made of metal or synthetic resin such as aluminum, stainless steel, or other alloy, and is formed of an operation portion 89 (head), a screw portion 90, and a slide stop roller 91. In the set screw 88, the top of the screw portion 90 is fixed to the operation portion 89, and the slide stop roller 91 is inserted and fixed to the bottom of the screw portion 90. The screw portion 90 is screwed into a screw hole (screw hole) formed in the upper plate 64 of the slider 20. When the operating portion 89 of the set screw 88 is rotated in the clockwise direction (positive direction), the threaded portion advances (moves) toward the connecting plate 55 (base plate 44) of the erection unit 16 and the operating portion 89 of the set screw 88. When the screw portion is rotated in the counterclockwise direction (counterclockwise direction), the screw portion retracts (moves) in a direction away from the connecting plate 55 (base plate 44) of the erection unit 16.

In order to use the set screw 88, a predetermined guideline 19 is used in the process of gradually sliding the slider 20 together with the swivel lever 73 from the lower end 63 of the guideline 19 toward the upper end 61 in the vertical direction while gripping the swivel lever 73. Stop the slide of the slider 20 at the point. When the slide of the slider 20 is stopped, the operation portion 89 (head) of the set screw 88 is rotated in the counterclockwise direction (counterclockwise direction), and the screw portion 90 is connected to the connecting plate 55 (base plate 44) of the erection unit 16. Retreat so as to be separated from. When the screw portion 90 is retracted, the tapered portion of the slide stop roller 91 attached to the screw portion 90 presses against the protrusions protruding inward from the inner surfaces of the second and third guide plates 50 and 52, and at that time. The slider 20 is fixed to the erection unit 15. By fixing the slider 20 to the erection unit 15, the slider 20 is prevented from sliding further upward, and the feeding of the first and second wires 15a and 15b in one direction (forward and backward) is stopped. ..

When the tapered portion of the slide stop roller 91 of the set screw 88 presses against the protrusions on the inner surfaces of the second and third guide plates 50 and 52 and the feeding of the wires 15a and 15b is stopped, the first and second guide plates are stopped. The free end 37 of the window bodies 13a and 13b stops turning downward in the vertical direction. The vertical and downward turning angles of the first and second window bodies 13a and 13b differ depending on the fixed position of the slider 20 in the guideline 19 using the set screw 88, and the open areas of the window bodies 13a and 13b when opened differ. ..

After fixing the slider 20 to the connecting plate 55 with the set screw 88, in order to release the fixing of the slider 20, the operation portion 89 of the set screw 88 is rotated in the clockwise direction (positive direction), and the screw portion 90 is connected to the connecting plate. 55 (base plate 44)). When the screw portion 90 is advanced, the tapered portion of the slide stop roller 91 is separated from the protrusions on the inner surfaces of the second and third guide plates 50 and 52, and the second and third guides by the tapered portion of the slide stop roller 91 are separated. The pressure on the protrusions on the inner surfaces of the plates 50 and 52 is released, the fixing of the slider 20 is released, and the slider 20 can be slid in the vertical direction.

The window opening / closing system 11 can adjust the upward movement distance (slide distance) of the slider 20 from the lower end 63 of the guideline 19 by adjusting the installation position of the stopper 87 in the guideline 19, and the first and second windows can be opened and closed. Since the turning angle of the rotating end portions 36 of the window bodies 13a and 13b can be adjusted downward from the upper frame 24, the open area of the window bodies 13a and 13b at the time of opening can be adjusted by the stopper 87. The air volume of the air passing through the window bodies 13a and 13b can be adjusted.

The window opening / closing system 11 arbitrarily fixes the free end portions 37 of the window bodies 13a and 13b downward from the upper frame 24 by fixing the slider 20 at a predetermined position of the guideline 19 using the set screw 88 (fixing means). Since the window bodies 13a and 13b can be opened while being swiveled at the angle of 1), the open area of the window bodies 13a and 13b at the time of opening can be adjusted by using the set screw 88. The air volume of the air passing through 13b can be adjusted.
