[0025]
As in the third embodiment, when the window opening / closing mechanism of the present invention is used for a sliding window, the inclination angle of the shoji 6 can be automatically adjusted by wind pressure or the like, which is effective for the purpose of maintaining a constant ventilation function as a ventilation window. It is.
[0026]
6 and 7 show a fourth embodiment of the present invention. In this embodiment, the idling mechanism 4 corresponding to the first to third embodiments is a cooperative action of a link mechanism Li and a clutch member Mc which will be described later. It plays that role.
[0027]
In the fourth embodiment, the same portions as those in the first to third embodiments are denoted by the same reference numerals and only different portions will be described. As shown in FIG. 6, the drive means 3 includes an operation switch 100, a control circuit 101, and a drive motor 102 with a reduction gear. As will be described later, the control circuit 101 drives the drive motor 102 based on the operation switch 100 to “window closed mode”, “window free open / close mode” as natural ventilation, and “window open mode” for smoke exhaustion. Is set selectively.
A cross member (not shown in FIG. 6) is fixed in a parallel state on the indoor side of the lower member 13 of the window frame 1, and a shaft 103 that is rotationally driven by a drive motor 102 is arranged in parallel with the cross member. 40.
Reference numeral 104 denotes an opening / closing arm provided in a pair on the shaft 103 for each window. A boss 104a is formed on the lower end of the shaft 103 so as to be freely rotatable. The upper end is connected to the link 106 via a pin 105. Connected to form a link mechanism Li. The end of the link 106 opposite to the pin 105 is pivotally supported via a pin 107 on the lower end of the vertical frame member 11 of the window frame 1.
[0028]
Reference numeral 108 denotes a transmission ring portion that forms the clutch member Mc, which is fixed to the shaft 103 at a position adjacent to the opening / closing arm 104 via a washer Wc. Fixed to the outer side of the transmission ring portion 108 is a transmission element 109 formed in a substantially inverted L shape comprising a horizontal piece 109a and a vertical piece 109b. The horizontal piece 109a of the transmission element 109 is located in an opposed state to the upper side surface portion 104d and the lower side surface portion 104c of the open / close arm 104, respectively.
[0029]
When the window is closed, as shown in FIG. 7A, the control circuit 101 is activated based on the operation of the operation switch 100, and the drive motor 102 is energized in the reverse direction. Along with this, the shaft 103 rotates, the horizontal piece 109a of the transmission element 109 in the transmission ring portion 108 fully presses the lower side surface portion 104c of the open / close arm 104, and the open / close arm 104 and the link 106 are reversed V. It is closed in a letter shape.
[0030]
Next, when the “window free opening / closing mode” is selected from the “closed window mode” in FIG. 7A by operating the operation switch 100, the drive motor 102 is energized in the forward direction. As a result, the horizontal piece 109a of the transmission element 109 is separated from the lower side surface 104c of the opening / closing arm 104, and as shown in FIG. In this state, the open / close arm 104 is not restrained by the transmitter 109 and can freely rotate around the shaft 103 via the boss 104a.
In this case, the frictional force between the opening / closing arm 104 and the link 106 of the link mechanism Li is set to be commensurate with (weight of the link mechanism Li) + (self weight of the shoji 2). For this reason, the link mechanism Li formed by the open / close arm 104 and the link 106 expands and contracts by negative pressure based on wind pressure or the like, and the shoji 2 can be displaced from the closed position of FIG.
[0031]
Further, when the drive motor 102 is energized in the positive direction via the control circuit 101 by operating the operation switch 100, the horizontal piece 109a of the transmitter 109 presses the upper side surface 104d of the open / close arm 104. Then, the opening / closing arm 104 rotates in the forward direction, the link 106 of the link mechanism Li rotates in the horizontal direction, and the window is opened as desired from the “window free opening / closing mode” as shown in FIG. It changes to "Open window mode". If the driving motor 102 is reversed by the operation switch 100 from this state and the horizontal piece 109a of the transmission element 109 is returned to the “window free opening / closing mode”, the shoji 2 can be freely moved in the opening / closing direction from the position of FIG. Can be displaced.
In this way, by rotating the drive motor 102 forward and backward by operating the operation switch 100 and setting the horizontal piece 109a of the transmitter 109 to the “window free opening / closing mode” shown in FIG. The shoji 2 can be freely opened and closed within a certain angle range. In particular, in the fourth embodiment, since the mechanism is attached only to the lower part of the window, the appearance is improved and the workability is improved.
[0032]
FIGS. 8A, 8B and 8C show a fifth embodiment of the present invention. The fifth embodiment differs from the fourth embodiment in that a block-shaped sector is provided in place of the transmitter 109 in the fifth embodiment.
That is, as shown in FIGS. 8B and 8C, the sector 110 is formed in a block shape as a clutch member Mc on the surface facing the transmission ring portion 108 and the boss portion 104a of the open / close arm 104, and forms a sector shape. 111 is provided in a bulging state. The sector 110 of the transmission ring portion 108 has a central angle of 180 degrees, for example, and the sector 111 of the boss portion 104a has a central angle of 45 degrees, for example. At this time, the central angles of the sectors 110 and 111 are not limited to 180 degrees and 45 degrees, but can be changed as appropriate according to usage conditions.
[0033]
In this case, the sector 110 of the transmission ring portion 108 and the sector 111 of the boss portion 104a mesh with each other through play of a difference between these central angles (180 degrees−45 degrees = 135 degrees). Therefore, the radially outer surface 110a of the sector 110 in the transmission ring portion 108 corresponds to the horizontal piece 109a of the transmitter 109 of the fourth embodiment, and the radially outer surfaces 111a, 111b of the sector 111 of the boss portion 104a. Corresponds to the upper side surface portion 104d and the lower side surface portion 104c of the open / close arm 104 of the fourth embodiment.
In this way, in the fifth embodiment, the operation of the fifth embodiment can be explained in the same manner as the fourth embodiment by substituting the equivalent members in the fourth embodiment. Thereby, the fifth embodiment has the same effect as the fourth embodiment.
[0034]
9 to 13 show a sixth embodiment of the present invention.
In the sixth embodiment, the clutch member Mc of the fifth embodiment in FIG. 8 is used, and the lock mechanism 120 is provided along the shaft 103 thereof. In this case, the sector 110 of the transmission ring portion 108 has a central angle of 180 degrees, and the sector 111 of the boss portion 104a has a central angle of 90 degrees. The lock mechanism 120 forcibly holds the unlocked state of the shoji 2 when the shoji 2 is displaceable in the opening and closing directions, and forcibly unlocks the shoji 2 when the shoji 2 is closed. Is canceled to return to the lockable state. Note that the central angles of the sectors 110 and 111 are not limited to 180 degrees and 90 degrees, but are arbitrary angles depending on the selection and usage of play between the sectors 110 and 111, such as 180 degrees and 45 degrees. Various settings can be made.
[0035]
In this lock mechanism 120, reference numeral 121 denotes a cam sleeve fitted to a predetermined portion of the shaft 103 as shown in FIGS. 9 and 10, and a cam groove 121a is formed on the surface of the cam sleeve. The cam groove 121a includes end grooves 121b and 121c carved in the circumferential direction at both ends of the cam sleeve 121, and a main groove 121d that slightly intersects the bus sleeve of the cam sleeve 121 and connects the end grooves 121b and 121c. .
Reference numeral 122 denotes a substrate, which is provided on the lower member 123 of the window frame 1 via a laying plate 122a so as to be positioned below the cam sleeve 121. As shown in FIG. 11, a claw portion 124 having a protrusion 124 a is disposed on the substrate 122 so as to be rotatable around a pin 125. The claw portion 124 is allowed to rotate only in the counterclockwise direction as indicated by an arrow K in FIG. 11, and is always pulled and urged by the tension coil spring 126 in the direction opposite to the arrow K in FIG. In the operating position shown.
Reference numeral 127 denotes a slider which abuts on the claw portion 124 and is provided on the substrate 122 so as to be reciprocally movable along the direction of the shaft 103. The slider 127 has a protrusion 127a located in the cam groove 121a, and slides between the lockable position and the free position via the protrusion 127a along with the rotation of the cam sleeve 121 together with the shaft 103. In the lockable position, the slider 127 places the claw portion 124 in the operating position indicated by the solid line, and in the free position, the claw portion 124 is pulled against the urging force of the coil spring 126 and is centered on the pin 125 in FIG. Press and move to the inoperative position shown.
[0036]
On the other hand, 128 is a tongue member constituting the lock mechanism 120, which is attached to the lower crosspiece 2 a corresponding to the lower edge 22 of the shoji 2. A tip-shaped guide portion 128a is formed at the distal end portion of the tongue member 128, and a notch portion 128b corresponding to the protruding portion 124a of the claw portion 124 is formed on the side surface portion. In the “window closing mode” in which the shoji 2 is fully rotated downward, the slider 127 is in the lockable position and the claw portion 124 is in the operating position. For this reason, the tongue member 128 enters and the guide portion 128a hits the projection 124a, temporarily rotates the claw portion 124 against the coil spring 126 in the direction of the arrow K, and the claw portion 124 The protrusion 124a is engaged and the shoji 2 is locked. In this state, since the claw portion 124 is restrained without being allowed to rotate in the direction of the counter arrow K, the tongue member 128 will not accidentally come out of the claw portion 124.
[0037]
This aspect is shown in the principle diagram of FIG. 12 and FIG.
(I) In the “window closing mode”, as shown in FIGS. 12A and 12A, the sector 110 of the boss 104a is prevented from rotating in the opening direction by the sector 110 of the transmission ring portion 108 of the clutch member Mc. Has been. The protrusion 127a of the slider 127 is in a lockable position located in the end groove 121b of the cam groove 121a, and the claw portion 124 in the operating position is engaged with the tongue member 128 to lock the shoji 2. .
(II) As the shaft 103 and the cam sleeve 121 rotate, only the sector 110 rotates counterclockwise by an angle of 90 degrees as shown in FIGS. Then, the sector 111 shifts to a “free open / close mode” in which the window 111 can freely move in the window opening and closing directions. At this time, by rotation of the shaft 103 and the cam sleeve 121, the protrusion 127a slides along the main groove 121d to reach the end groove 121c, and the slider 127 moves from the lockable position in FIG. The claw portion 124 is moved from the operating position to the inoperative position of the two-dot chain line against the tension coil spring 126. This forcibly disengages the claw portion 124 with respect to the tongue member 128 and opens the tongue member 128. The shoji 2 can realize a “free open / close mode” between positions where the open / close arm 104 and the link 106 change as shown by a solid line and a two-dot chain line in FIG.
(III) Further, when the sector 110 is rotated counterclockwise by an angle of 90 degrees as shown in FIGS. 12C and 12C, the sector 111 is pushed and rotated 90 degrees in the same direction. . As a result, the shoji 2 is in the “window opening mode” at the position of the opening / closing arm 104 and the link 106 indicated by a two-dot chain line in FIG. Then, the protrusion 127a of the slider 127 moves to the end of the end groove 121c and holds the claw portion 124 in the inoperative position.
In the above description, the mode switching between the “window closing mode”, “free open / close mode”, and “window opening mode” rotates the sector 110 by 90 degrees, but this rotation angle is 90 degrees. The opening angle (θ) of the shoji 2 and the lengths of the open / close arm 104 and the link 106 are taken into consideration according to the use situation and the like, and the desired angle can be set as appropriate.
[0038]
Thus, particularly in the “free open / close mode”, the claw portion 124 of the tongue member 128 is in the inoperative position and is released from the engagement of the claw portion 124. For this reason, even if the shoji 2 is closed by the wind pressure, the lock mechanism 120 does not operate and it is not locked by mistake.
In addition, the claw 124 is activated with respect to the tongue member 128 only when the “window closing mode” is performed. As a result, the tongue member 128 of the lock mechanism 120 is automatically engaged with the claw portion 124 as the shoji 2 is locked as the shoji 2 is closed. For this reason, timing adjustment at the time of locking by engagement is unnecessary as compared with a combination of a wire, a screw rod, and a nut, and the work can be completed in a short time and easy to install.
[0039]
This locking mechanism 120 is applied in the fourth embodiment shown in FIGS. 6 and 7 and can be used as the seventh embodiment of the present invention.
[0040]
14 and 15 show an eighth embodiment of the present invention. In the eighth embodiment, the present invention is applied to a rotary screen 129 that does not require the link mechanism Li. The rotating shoji 129 has a rectangular shape, and the central portions of the left and right vertical bars 129a and 129b are rotatably supported by the left and right vertical frame members 130a and 130a of the window frame 130, respectively. 131 is a support | pillar, and this is being fixed along the vertical frame member 130a. Opening / closing arms 132 are rotatably provided by pins 133 on the left and right side portions of the support column 131. A roller 134 is attached to the front end of the opening / closing arm 132 so as to slide up and down to open and close the rotary sliding door 129 by sliding on the vertical rail portion 129a (129b).
[0041]
A turning unit 135 includes a coupling, a chain gear, a gear train, and the like (not shown). The rotation of the shaft 103 is controlled by a “window closing mode”, a “free opening / closing mode”, and a “window opening”. The open / close arm 132 is driven to a predetermined rotational position via the chain 136 in accordance with the “mode”. In this case, the turning mode of the opening / closing arm 132 from the turning unit 135 through the chain 136 is as follows.
[0042]
(A) In the “window closing mode”, the open / close arm 132 presses the upper part from the center of rotation of the vertical beam portion 129a (129b) via the roller 134 as shown in FIG. 129 is closed. In this case, the rotary door 129 is locked in the closed state by the lock mechanism 120, and corresponds to (A) and (a) of FIG.
(Ii) In the “free open / close mode”, the open / close arm 132 rotates counterclockwise by a predetermined angle (φ1). As a result, as shown in FIG. 15B, the roller 134 is separated from the vertical beam portion 129a (129b) in the open / close arm 132. At this time, the rotary shoji 129 is restrained from the open / close arm 132 and is in a position corresponding to (B) and (b) of FIG.
(C) Further, in the “window opening mode”, the open / close arm 132 pushes the lower part from the center of rotation of the vertical beam portion 129a (129b) via the roller 134 as shown in FIG. As a result, the rotary screen 129 is opened and rotated upward by a predetermined angle (φ2), and is in a position corresponding to (C) and (c) of FIG.
Even if comprised in this way, the effect similar to the 6th and 7th Example is acquired.
[0043]
In the above embodiment, the cam sleeve 121 is fitted to the shaft 103 in order to form the cam groove 121a. However, the cam groove 121a may be formed directly on the shaft 103.
In specific implementation, various modifications and changes can be made without departing from the scope of the present invention.
