As shown in Figures 6(a) and (b) and Figures 9(a) and (b), the portion 164 of the cam surface 135 on the line 48 is larger than the portion 165 of the cam surface 135 on the line 160. It is away from the rotation axis of the cam body 151 having the same axis as the rotation axis C1. The distance d1 from the portion 164 to the rotation axis C1 is longer than the distance d2 from the portion 165 to the rotation axis C1. The distance D from the cam surface 135 to the rotational axis C1 gradually increases from the portion 165 toward the portion 164. The cam surface 135 gradually deflects the abutting end portion 140 against the rotating shaft center C1 during the rotation of the turning arm 51 in the R1 direction, and rotates the abutting end portion 140 in the rotation of the turning arm 51 in the R2 direction. The axis C1 is gradually approaching. The cam faces 134 and 135 are point-symmetric in relation to the rotational axis of the cam body 151.

The guiding member 156 is disposed on the side of the turning arm 51 with respect to the guiding member 157, and is fastened to the end of the turning arm 51 on the side of the push window 4. The guiding member 157 is disposed on the side of the vertical frame 24 with respect to the guiding member 156. Since the guide members 156 and 157 which are disposed to face each other in the lateral direction Y are formed in the same manner, the guide member 156 will be described in detail below, and the guide member 157 will be denoted by the same reference numerals in the drawings, and the detailed description thereof will be omitted. Description.

The guide member 156 includes the portions 171 and 172 which are perpendicular to the circumferential edges of the cam faces 134 and 135 in the direction orthogonal to the rotational axis of the cam member 136 having the same axis as the rotational axis C1. The portion 171 guides a portion of the cam surface 137 that abuts against the steel wire 137 along the cam surface 134, and the portion 172 guides the portion of the cam surface 138 that abuts against the steel wire 138 along the cam surface 135. The portions 171 and 172 are point-symmetric in relation to the rotational axis of the guiding member 156. A recessed portion 173 into which the fitting portion 183 of the steel wire 137 is fitted is formed in the mounting portion 154 of the guide member 156, and a recessed portion in which the fitting portion 184 of the steel wire 138 is fitted is formed in the mounting portion 155 of the guide member 156. 174. The recess 173 is disposed such that the cam surface 134 is located between one end 143 and the other end 152 of the steel wire 137. The recess 174 is disposed such that the cam surface 135 is located between one end 146 and the other end 153 of the steel wire 138. The guiding member 156 rotates together with the rotation of the cam body 151.

At one end 143 and 146 of the steel wires 137 and 138, a ring portion 182 is formed on the hook portion 181 formed at the other ends 142 and 145 of the tension springs 132 and 133, at the other end 152 of the steel wires 137 and 138 and Cylindrical fitting portions 183 and 184 fitted to the concave portions 173 and 174 of the guiding members 156 and 157 are formed on the 153. The steel wire 137 abuts the cam surface 134 while the push window 4 is in the open closed position, and the abutting end portion 139 on the side of the tension spring 132 in the abutting region abuts against the cam surface 134. Part 162. The steel wire 137 abuts against the cam surface 134 while the push window 4 is in the open position of the opening, and the abutting end portion 139 on the side of the tension spring 132 in the abutting region abuts against the cam surface 134. Part 161. The steel wire 138 abuts the cam surface 135 while the push window 4 is in the open position of the opening, and the abutting end portion 140 on the side of the tension spring 133 in the abutting region abuts against the cam surface 135. Part 165. The steel wire 138 abuts the cam surface 135 while the push window 4 is in the open position of the opening, and the abutting end portion 140 on the side of the tension spring 133 in the abutting region abuts against the cam surface 135. Part 164.

The tension springs 132 and 133, the steel wires 137 and 138, and the cam faces 134 and 135 are biased by the tension spring 132 in the R1 direction to the turning arm 51 via the steel wire 137 and the cam member 136, and the tension spring 133. The rotational force in the R1 direction given to the turning arm 51 via the steel wire 138 and the cam member 136 is equal to each other, and is arranged in point symmetry with respect to the rotational axis C1.

When the urging mechanism 5 is used, the rotational force of the rotating arm 51 in the R1 direction is given according to the tensile force of the tension springs 132 and 133, and the push window 4 can be biased toward the open open position, and the rotating arm 51 is at the R1. During the rotation of the direction, the abutting ends 139 and 140 of the pair of cam faces 134 and 135 of the steel wires 137 and 138 are gradually separated from the rotational axis C1, and the tension spring is gradually reduced in accordance with the rotation of the rotating arm 51 in the R1 direction. The tensile force of 132 and 133 can impart a substantially constant rotational force in the R1 direction to the turning arm 51, so that the window 4 can be biased toward the opening opening position by a substantially constant moving force. Further, when the urging mechanism 5 is used, since the abutting ends 139 and 140 gradually approach the rotating shaft center C1 in the movement of the push window 4 toward the closed position of the opening, the rotation of the turning arm 51 in the R2 direction can be gradually made. The tensile force of the tension springs 132 and 133 is increased, and the rotational force of the R2 direction is hardly increased on the rotating arm 51, so that the push window 4 can be made resistant to the window 4 toward the opening. The movement of the closed position is substantially constant against the moving force.

Further, the urging mechanism 5 may be provided with a compression spring (not shown) that applies a rotational force in the R1 direction to the turning arm 51 via the steel wire 137 and the cam member 136, respectively, in place of the tension spring 132. One end 143 of the steel wire 137 may be attached to the fixed end of the vertical frame 24 to the compression end, and connected to the movable end located on the side of the upper frame 22. Further, the urging mechanism 5 may be provided with the same compression spring as described above instead of the tension spring 133. Further, the elastic member of the urging mechanism 5 of the present embodiment is a torsion spring, but may be constituted by a pneumatic or hydraulic cylinder or the like instead of this.

The window switch device 1 further includes a stopper member that stops the push window 4 at the closed position and stops the window frame 2 so as not to freely release the movement of the push window 4 toward the opening open position by the urging mechanism 5 (none Graphic). The stopping member can also be rotated by the operation when the window 4 is pushed in the closed position, and then stopped in the window frame 2, if it is stopped in the lower frame 13, and is reversely rotated by the operation, and the lower frame is released. The manner of stopping the 13 is to be freely rotatably mounted to the frame 23 below the push window 4.

The window switch operation of the above window switch device 1 is explained below. First, the window 4 is released by the stopper member by the operation. When the mechanism is released, the turning arm 51 that imparts the rotational force in the R1 direction according to the elasticity of the tension springs 132 and 133 rotates the rotating shaft center C1 as the center in the R1 direction, and is closed at the opening position by the rotation. The moving force A is applied to the push window 4, so that the push window 4 at the closed position of the opening is moved toward the open open position by the urging force of the urging mechanism 5. In the rotation of the rotating arm 51 in the R1 direction, the end of the rotating arm 51 on the side of the window frame 2 is guided to the guiding path 71 and directly moved upward, and the connecting arm 61 rotates in the R1 direction according to the rotating arm 51. The rotation axis C4 is centered on the r1 direction. In this way, the rotating shaft center C1 of the turning arm 51 rotating in the R1 direction at the end portion of the pushing window 4 side is moved in an approximately parallel motion from the inside of the building 8 toward the outside of the building 7 in the direction X and the inside and outside of the building. In a linear motion, the portion 33 also moves from the inside of the building 8 toward the outside of the building 7 in the direction X inside and outside the building. In the case where the push window 4 is in the open closed position, the tensile force B of FIG. 6(a) is large depending on the elasticity of the tension springs 132 and 133, but since the abutting ends 139 and 140 to the rotating shaft center C1 Since the distance shown in (b) of FIG. 6 is the shortest distance d2, the tensile force B of the tension springs 132 and 133 is canceled and transmitted to the turning arm 51.

As described above, the push window 4 that is moved toward the opening open position by the urging force of the urging mechanism 5 moves to the opening open position through the position shown in FIG. With the movement of the push window 4, the tensile amounts of the tension springs 132 and 133 are gradually decreased, and the tensile force B is gradually reduced, however, due to the distance from the abutting ends 139 and 140 to the rotational axis C1 ( The distance equal to the distance D is gradually increased. Therefore, depending on the tensile force B of the tension springs 132 and 133, the rotational force imparted to the rotating arm 51 in the R1 direction is hardly reduced, and the push window 4 is closed at the opening. In the positional position, the rotational force in the R1 direction given to the turning arm 51 is substantially equal.

When the push window 4 reaches the open open position by the movement toward the open position of the opening, since the tensile amounts of the tension springs 132 and 133 of the present example are zero, the drawing of the tension springs 132 and 133 is not generated. The rotational force B of the tensioning force B shown in (a) does not generate the moving force A given to the portion 33 from the turning arm 51, so that the push window 4 is stationary at the opening open position. In the case where the push window 4 is in the open position of the opening, the distance from the abutting ends 139 and 140 to the rotational axis C1 is the longest distance d1. When the push window 4 is in the open position of the opening, the rotation axis C2 is also located below the rotation axis C1. In addition, the upper end of the guiding path 71 abuts against the shaft body 72 when the push window 4 reaches the opening open position, and prohibits the direct movement of the end portion to the upper side, because the shaft body 72 is prohibited from moving upward. Since the movement of the push window 4 toward the open position of the opening is prohibited, it is also possible to arrange the tension springs 132 and 133 to retain the tensile force B even when the push window 4 reaches the open position of the opening.

When the push window 4 is in the open position of the opening, the outer side 7 of the building forms a positive pressure with respect to the push window 4 according to the air flow, and when the inner side 8 of the building forms a negative pressure than the push window 4, the push window 4 is given according to the air flow. The moving force toward the closed position of the opening. When the push window 4 moves toward the open closed position in accordance with the aforementioned moving force of the air flow, the flow rate of the gas flowing into the outside of the building 7 and the inside of the building 8 is reduced. The movement of the push window 4 toward the closed position of the push window 4 is based on the air flow, and the moving force toward the closed position according to the air flow is higher than the weight of the push window 4 from the rotating arm 51 according to the elasticity of the tension springs 132 and 133. A certain movement force A is generated. Since the moving force A of the turning arm 51 to the push window 4 is substantially constant, and even if the pushing window 4 is hardly increased toward the opening closed position, the pushing window 4 that gives the moving force toward the opening closed position according to the air flow can be The moving force rapidly moves toward the open closed position, so that strong wind from the outside of the building 7 toward the inside of the building 8 can be prevented from passing through the opening 3. On the other hand, when the outside of the building 7 forms a negative pressure than the push window 4 by the air flow, and the 8 sides of the building form a positive pressure than the push window 4, the moving force toward the opening open position is given to the push window 4. When the push window 4 moves toward the opening open position by the moving force toward the opening open position according to the air flow, the flow rate of the gas flowing into the outside of the building 7 and the inside of the building 8 increases. When the moving force of the push window 4 in accordance with the opening position of the airflow opening direction and the moving force toward the opening closing position are not generated, the push window 4 is biased by the urging mechanism 5, and returns to the opening open position to be stationary.

When the push window 4 in the open position is moved toward the open closed position by operation, the rotating arm 51 rotates in the R2 direction opposite to the direction R1, and the shaft 72 is guided to the guiding path 71 by the rotation and is directly moved. Below. The link arm 61 rotates in the R2 direction as the turning arm 51 rotates, and rotates in the r2 direction opposite to the r1 direction. Thus, when the turning arm 51 rotates in the R2 direction, the rotating shaft center C1 moves approximately parallel from the outside of the building 7 toward the inside of the building 8 in the direction X inside and outside the building. In this example, a strict linear motion is performed, whereby the portion 33 is also The direction X inside and outside the building is strictly linearly moved from the outside of the building 7 toward the inside of the building 8. As described above, the tension springs 132 and 133 are stretched when the turning arm 51 is rotated in the R2 direction. Therefore, the turning arm 51 is given a rotational force in the R1 direction. However, since the rotational force in the R1 direction is substantially constant, The push window 4 is easily moved toward the open closed position by operation. The push window 4 that is moved to the open closed position by the operation is stopped by the sash member to maintain the opening 3 in the fully closed state. Further, the resistance against the movement of the push window 4 toward the open closed position in accordance with the air flow, even if the shaft 72 is gradually guided by the relationship of the rotational angle of the rotary arm 51 which changes according to the rotation of the air flow rotating arm 51 in the R2 direction The resistance of the path 71 and the resistance of the shaft 72 to the guide path 71 which are gradually increased by the urging mechanism 5 imparting a substantially constant rotational force in the R1 direction to the turning arm 51 can be surely approached.

When the window switch device 1 of the present embodiment is used, it has: a window frame 2 installed in a building; a window 3 disposed in the opening 3 divided into the window frame 2, and opening and closing the opening 3; The connection mechanism 32 that rotatably couples the window 4 to the window frame 2 at a portion 31 on one side in the vertical direction V in a manner that the air flow is free to open the opening 3; and in order to bias the push window 4 toward the open position of the opening The urging mechanism 5 is connected to the push window 4 and the window frame 2; the urging mechanism 5 is provided to be rotatably coupled to the portion 31 of the push window 4 and to the other portion 33 in the vertical direction V at different positions, and The portion 33 is present in the vertical direction V at the location 15 of the sash 2 at different positions, and by the rotation, the portion 33 is provided with a rotating arm 51 from the inside of the building 8 to the side 7 of the building; The sash 2 is provided on one of the window 4 and the sash 2, and guides the sash of the sash 2 with the rotation of the rotating arm 51. This example guides the direct guiding path 71; And a tension spring 132 as an elastic member of the push window 4 of the other of the window frames 2; fastened to the rotation 51. The cam member 136 having the cam surface 134; and the tension spring 132 and the cam member 136 are coupled to each other, and the R1 direction for imparting the moving force A to the portion 33 by the elasticity of the tension spring 132 via the cam member 136 The rotational force imparts to the rotating arm 51 in a manner that has a flexible steel wire 137 that abuts the flexible surface of the cam surface 134; since the cam surface 134 is attached to the steel wire 137 abutting the cam surface 134 The abutting end portion 139 of the tension spring 132 side pushes the other portion of the push window 4 and the window frame 2 from the turning arm 51 in the rotation of the rotating arm 51 for the moving force A in the R1 direction. The rotation axis C1 of the window 4 is gradually formed away from each other, so that the change in the amount of stretching of the spring 132 can be caused by the opening and closing of the window 3 with the opening of the window 4, and the change of the rotational force to the rotating arm 51 is reduced, so that The moving force of the push window 4 toward the open position of the opening can be surely approached.

When the window switch device 1 is used, since the elastic member is gradually reduced in the movement of the push window 4 toward the open position of the opening, the push window 4 of the other of the push window 4 and the window frame 2 is attached. Since the tension spring 132 is configured, the amount of tension of the tension spring 132 can be gradually decreased in accordance with the movement of the push window 4 toward the opening open position, and the steel wire 137 abutting on the cam surface 134 abuts on the side of the tension spring 132. The end portion 139 is provided with the turning arm 51 for the moving force A from the building 8 side toward the building exterior 7 side in the rotation in the R1 direction, and gradually deviates from the rotating shaft center C1, so that it can be surely The moving force of the push window 4 toward the open position of the opening is approached.

When the window switch device 1 is used, since the cam member 136 has the other cam surface 135, the biasing mechanism 5 includes a tension spring as another elastic member that is mounted on the other of the push window 4 and the window frame 2 133; and the tension spring 133 and the cam member 136 are coupled to each other, and the rotational force of the R1 direction for imparting the moving force A by the elastic pair portion 33 of the tension spring 133 is given to the turning arm 51 via the cam member 136. a steel wire 138 that is a flexible other of the flexible body that abuts against the cam surface 135; the cam surface 135 is abutting the end 140 of the steel wire 138 abutting the cam surface 135 on the side of the tension spring 133 The portion 33 is formed so as to gradually deviate from the rotation axis C1 in the rotation of the rotary arm 51 for the movement force A in the R1 direction. Therefore, the rotation arm 51 is given a substantially constant R1 in accordance with the elasticity of the tension spring 132. In addition to the rotational force of the direction, a rotational force of a substantially constant R1 direction of the rotating arm 51 may be imparted to the rotating arm 51 in accordance with the elasticity of the tension spring 133, and even if one of the steel wires 137 and 138 is not Unexpected cutting, etc. When the elasticity of one of 132 and 133 imparts a rotational force in the R1 direction to the turning arm 51, the rotational force of the R1 direction can be imparted to the turning arm 51 according to the elasticity of the other of the tension springs 132 and 133, so that even When an unexpected obstacle is generated in the urging mechanism 5, the push window 4 can be prevented from moving rapidly toward the closed position of the opening.

When the window switch device 1 is used, since the cam member 136 is rotated by the rotation arm 51 as a center, the cam member 136 is fastened to the rotary arm 51, the tension spring 132, the cam surface 134, and the steel wire 137. The tension spring 133, the cam surface 135, and the steel wire 138 are disposed so as to be point-symmetric in the relationship with the rotation axis C1. Therefore, the cam member 136 due to the elasticity of the tension springs 132 and 133 can be avoided. By imparting an unexpected rocking power, the turning arm 51 can be more preferably imparted with a turning force. Further, the tension springs 132 and 133 preferably have elasticity equal to each other.

When the window switch device 1 is used, the guide path 71 is provided in the window frame 2 so as to guide the direct movement of the window frame 2 with the rotation of the rotary arm 51, and the portion 33 is disposed at the same position as the center of gravity G of the push window 4. Therefore, when the opening 3 is opened by the push window 4, the moving force toward the opening open position and the moving force toward the open closed position according to the self-weight of the push window 4 are not generated, and the window 4 can be pushed by the urging mechanism 5 A substantially constant moving force A of the opening open position urges the window 4.

When the window switch device 1 is used, the urging mechanism 5 is provided with a portion 52 that is rotatably coupled between the rotation axes C1 and C2 of the rotation arm 51, and the portion 52 is located on the rotation axis C1 side in the vertical direction V. The connecting arm 61 of the portion 16 of the sash 2 and the guiding path 71 are free to extend the axis of rotation C2 on a line passing through the axis of rotation C2 and the vertical direction V of the connecting arm 61 to the axis of rotation C4 of the sash 2 In the sash 2, the connection mechanism 32 connects the portion 31 to the window frame 2 so as to be freely movable, and the length L1 and the rotation from the rotation axis C3 of the rotation arm 51 to the rotation axis C4 from the connection arm 61. The ratio of the length L2 of the axis C2 to the rotation axis C3 is equal to the ratio of the length L2 to the length L3 from the rotation axis C1 to the rotation axis C3. Therefore, when the opening 3 is opened by pushing the window 4, the position 33 can be The so-called approximate parallel motion is performed. Further, when the window switch device 1 is used, since the length L2 is equal to the length L3, when the opening 3 is opened by pushing the window 4, strict linear motion can be performed on the portion 33.

When the window switch device 1 is used, the link mechanism 32 freely rotates and slidably connects the upper portion 31 of the push window 4, and the pivot arm 51 is rotatably coupled to the portion 33 located below the portion 31, and the rotary shaft The core C2 is disposed below the rotation axis C1, and the rotation axis C4 is disposed above the rotation axis C2. Therefore, even when the connection mechanism 32 and the urging mechanism 5 are disposed close to each other, the window opening 4 is opened in the window 3. The urging mechanism 5 does not interfere with the connection mechanism 32, and the degree of freedom in the arrangement of the connection mechanism 32 and the urging mechanism 5 can be improved, and the window 4 of various sizes can be coupled to the window frame 2.

Composition. One end 104 of the compression spring 103 is mounted to the lower portion of the fixed body 87, and the other end 105 of the compression spring 103 is supported by the vertical frame 14. The compression spring 103 is compressed by the direct motion of the downward direction of the unidirectional damper 83 according to the direct movement of the sash 2 downward according to the rotating arm 51, and by the compression, the vertical direction V is upward. The urging force is applied to the one-way damper 83. Further, by the direct movement of the sash 2 toward the upper side by the rotating arm 51, and the communication member 86 is separated from the unidirectional damper 83, the unidirectional damping is squeezed by the aforementioned urging force. The device 83 is moved straight upwards to return it to the initial position. Further, a guide member 106 having a guide path for guiding the expansion and contraction of the compression spring 103 may be disposed around the compression spring 103.

The transmission member 86 is configured by an L-shaped plate-shaped member 109 that is attached to the end portion of the turning arm 51 on the side of the window frame 2 and that abuts against the abutting surface 108 of the upper surface 107 of the fixed body 87. The plate-like member 109 is directly moved by the direct movement of the end portion of the turning arm 51 on the side of the window frame 2 in the vertical direction V. The abutting surface 108 of the plate-like member 109 is disposed such that the push window 4 abuts against the upper surface 107 of the fixed body 87 when the push window 4 is located near the closed closed position. The plate-shaped member 109 rotates the downward movement of the sash 2 toward the lower side by the movement of the push window 4 toward the opening closed position, and moves straight downward, whereby the abutting surface 108 abuts against the direct contact In the upper surface 107, the direct motion is transmitted to the one-way damper 83, so that the rotary body 82 is rotated in the R3 direction, and the one-way damper 83 is moved directly downward toward the rack shaft member 102, and further, The sash 2 is moved straight upward by the direct movement of the sash 2 toward the upper side, and the abutting surface 108 is separated from the upper surface 107 by the direct motion. In addition, when the abutting surface 108 is in contact with the upper surface 107 in the communication member 86 and the unidirectional damper 83, the fitting surface 108 may be fitted to each other, and when the abutting surface 108 is separated from the upper surface 107, the fitting convex portion may be released. The fitting portion 110 and the fitting recess portion 111, and the fitting convex portion 110 and the fitting recess portion 111 are also fitted to each other, and the mutual communication member 86 and the unidirectional damper 83 are prohibited from being in contact with each other in the direction X and the lateral direction Y of the building. Positional deviation.

The damping mechanism 81 moves directly toward the lower side of the window frame 2 according to the movement of the push window 4 toward the closed position of the opening, and the communication member 86 is directly moved downward, and the abutting surface 108 abuts by the direct motion. In the upper portion 107, the direct motion downward is transmitted to the one-way damper 83, and by the transmission, the one-way damper 83 is relatively moved downward toward the rack shaft member 102, and the gear 98 is generated by the movement. The rotation in the R4 direction is transmitted to the rotating body 89 via the one-way clutch 91, and by this transmission, the rotating body 89 is relatively rotated in the R3 direction with respect to the fixed body 87, thereby generating the viscous resistance of the viscous body 88, and thus pushing Before the window 4 reaches the closed position of the opening, the direct movement of the rotating arm 51 toward the lower side of the window frame 2 is attenuated by the damping force depending on the linear motion speed. Further, since the damping mechanism 81 rotates in the R4 direction of the gear 98, the relative rotation of the rotating body 89 with respect to the fixed body 87 is not generated, so that the transmission member 86 is damped from the unidirectional direction with the movement of the push window 4 toward the open position of the opening. When the device 83 faces away, the unidirectional damper 83 can be quickly returned to the initial position by the urging member 85.

When the push window 4 is moved from the open closed position shown in FIG. 10 to the vicinity of the open closed position shown in FIG. 15, the one-way damper 83 is biased by the biasing member 85, and the abutting member 84 is in the vertical direction. V is moved upward, and therefore, the gear 98 is rotated in the R4 direction. However, since the rotation is not transmitted to the rotating body 89 by the one-way clutch 91, rotation of the fixed body 87 of the rotating body 89 is not generated, so that the window is not attenuated. 4 Move from the closed position of the opening to the vicinity of the closed position of the opening. When the push window 4 is moved from the vicinity of the closed position to the open position of the opening, since the communication member 86 is separated from the one-way damper 83, the relative rotation of the rotating body 82 and the fixed body 87 is not generated, so that the movement is not attenuated. In addition, the push window 4 moves according to the airflow toward the open closed position, and when reaching the vicinity of the open closed position, the communication member 86 abuts against the one-way damper 83, and by the abutment, according to the rotation of the rotating arm 51 in the R2 direction, The direct motion of the rotating arm 51 toward the lower end of the sash 2 is transmitted to the one-way damper 83 via the communication member 86, and the unidirectional damper 83 transmits the force against the urging member 85 by the transmission. The shaft member 102 is moved downward, and the gear 98 is rotated in the R3 direction by the movement. The rotation is transmitted to the rotating body 89 via the one-way clutch 91, and the rotating body 89 relatively rotates the fixed body 87 by the transmission, resulting in stickiness. The viscous resistance of the shear of the body 88 is such that the movement of the push window 4 located near the open closed position toward the open closed position is attenuated by the damping force depending on the moving speed. Further, since the damping mechanism 81 does not cause the relative rotation of the rotating body 89 to the fixed body 87 when the gear 98 rotates in the R4 direction, the rotating arm 51 rapidly moves straight toward the upper side of the window frame 2, so that the window can be pushed up. 4 moves lightly toward the opening open position shown in FIG.

The window switch device 80 may further include one of the one-way damper 83 and the abutting member 84 as shown in FIGS. 17 to 19, and the one-way damper 83 of this example is installed in the opening as shown in FIG. In the vicinity of the closing position, the push window 4 is moved toward the opening closed position shown in FIG. 17, and the portion of the rotating arm 51 that directly moves the window frame 2, in this example, the end of the rotating arm 51 on the side of the window frame 2, one-way The other of the damper 83 and the abutting member 84, in this example, the abutting member 84 is fastened to the damping mechanism 112 of the sash 2 instead of the damping mechanism 81.

The attenuation mechanism 112 that attenuates the movement of the push window 4 in the vicinity of the closed position of the opening toward the closed position of the opening, similarly to the damping mechanism 81, has a rotating body 82 and is attenuated in the R3 direction according to one direction of the rotating body 82. a one-way damper 83 that rotates against the resistance of the rotating arm 51 to the direct motion of the window frame 2 in the movement of the push window 4 near the closed position of the opening toward the closed position of the opening; and by abutting against the rotating body 82 The relative movement of the one-way damper 83 in the state, the rotation body 82 is rotated in one direction of the abutment member 84; the one-way damper 83 and the one-way unidirectional damper 83 of the abutment member 84 are based on The aforementioned linear movement of the turning arm 51 produces the aforementioned relative movement of the unidirectional damper 83 and the other abutting member 84 of the abutting member 84. In this example, the fixed body 87 of the one-way damper 83 is attached to the end of the sash 2 side of the rotating arm 51, the abutting member 84 is fastened to the sash 2, and the abutting body 90 is constituted by the gear 98, and the abutting member 84 is composed of a rack shaft member 102.

The damping mechanism 112 rotates the arm frame 51 downwardly according to the movement of the push window 4 toward the closed position of the opening, and the one-way damper 83 moves directly downward, and the push window 4 is located near the closed position of the opening. When the gear 98 is engaged with the rack teeth 101 of the rack shaft member 102, in the direct motion below the one-way damper 83, the gear 98 is relatively moved to the rack teeth 101, and The rotation of the gear 98 generated by the movement in the R3 direction is transmitted to the rotating body 89 via the one-way clutch 91, and by this transmission, the rotating body 89 is relatively rotated in the R3 direction with respect to the fixed body 87, so that the viscosity of the adhesive body 88 is made. The resistance is generated, and then, before the push window 4 reaches the open closed position, the direct movement of the rotating arm 51 toward the downward direction of the sash 2 is attenuated by the damping force depending on the linear motion speed. In addition, since the damping mechanism 112 does not rotate relative to the fixed body 87 by the rotation of the gear 98 in the R4 direction, the rotating arm 51 rapidly moves the window frame 2 upward, so that the window 4 can be oriented. The open position of the opening shown in 19 moves briskly.

The damping mechanism 112 can further be supported by the vertical frame 14 and abutting in the direct motion of the rotating arm 51 to the window frame 2 generated by the movement of the sliding window 4 near the closed position of the opening toward the closed position of the opening The end portion of the turning arm 51 on the side of the window frame 2 is provided with a compression spring 121 that resists the above-described direct motion against direct power.

When the damping mechanisms 81 and 112 are used, since the rotating body 82 is provided and the attenuation is caused in accordance with the rotation of the rotating body 82, the push window 4 located near the opening closed position is moved toward the open position of the opening. a one-way damper 83 that rotates the resistance of the arm 51 to the direct motion of the window frame 2; and the relative movement of the one-way damper 83 in a state of abutting against the rotating body 82, the rotating body 82 is rotated The abutting member 84 in one direction; one of the one-way damper 83 and the abutting member 84 generates the aforementioned relativity to the other of the one-way damper 83 and the abutting member 84 in accordance with the aforementioned linear motion of the rotating arm 51. Moving, so that the movement of the push window 4 toward the closed closed position can be attenuated before the push window 4 reaches the open closed position, so that the collision of the push window 4 against the window frame 2 can be prevented. The one-way damper 83 includes a fixed body 87 that is disposed to have a gap with respect to the rotating body 82, and a viscous body 88 that is disposed in a gap between the rotating body 82 and the fixed body 87. The rotating body 82 is provided with a fixed body 87. The relative rotation is performed so as to shear the adhesive body 88, and the rotation body 89 is disposed in the rotating body 89 of the fixed body 87; and the abutment member 84 is rotatably abutted against the abutting member 84 by the movement of the contact member 84. The engaging body 90; and the movement of the abutting member 84 by the direct movement of the rotating arm 51 by the rotating arm 51 which is generated in the movement of the sliding window 4 located near the closed position of the opening toward the closed position of the opening, the abutting body The rotation of 90 is transmitted to the rotating body 89, and the reverse rotation of the abutting body 90 is not transmitted to the rotating body 89, but the one-way clutch 91 between the abutting body 90 and the rotating body 89; The clutch 91 and the reverse rotation of the abutting body 90 are not transmitted to the rotating body 89. Therefore, when the push window 4 is moved toward the opening open position, resistance due to the relative movement of the unidirectional damper 83 and the abutting member 84 is not generated. Move the push window 4 toward the open position of the opening briskly Row. In the damping mechanism 81, the one-way damper 83 of one of the one-way damper 83 and the abutting member 84 is for generating the relativity to the abutting member 84 of the other of the one-way damper 83 and the abutting member 84. Moving, in the movement of the push window 4 located near the closed position of the opening toward the closed position of the opening, abutting against the rotating arm 51 as a part of the rotating arm 51 that swings one of the push window 4 and the window frame 2 in the window frame The end portion of the two sides is disposed in the sash 2, and the unidirectional damper 83 or the abutting member 84 is not disposed in the rotating arm 51. Therefore, the movement of the sash window 4 toward the open position of the opening and the opening are closed. The movement of the position is carried out briskly. The damping mechanism 81 further includes a one-way damper 83 that is one of the one-way damper 83 and the abutting member 84, and returns the other one of the one-way damper 83 and the abutting member 84 to the abutting member 84. The urging member 85 is biased in a positional manner so that the attenuation of the movement of the push window 4 located near the closed position of the opening toward the closed position of the opening can be repeated. In the damping mechanism 112, since one-way damper 83 of one of the one-way damper 83 and the abutting member 84 is installed in the movement of the push window 4 located near the closed position of the opening toward the closed position of the opening, The one of the window 4 and the window frame 2, which is a portion of the turning arm 51 which is a part of the turning arm 51, is on the side of the window frame 2, and the other one of the one-way damper 83 and the abutting member 84 abuts the member 84. Since it is fastened to the window frame 2, even if the damping mechanism 112 does not have the above-described biasing member 85, the attenuation of the movement of the push window 4 located near the closed position of the opening toward the closed position of the opening can be repeatedly performed. Since the window switch device 80 includes both the urging mechanism 5 and the damping mechanism 81 or 112, the above-described preferable effects can be obtained. However, even if the urging mechanism 5 is not provided, the effect of the damping mechanism 81 or 112 can be obtained.
