As shown in FIG. 4A, the lock mechanism 7 includes an engaging portion 7B, an engaged portion 7A, and the like. As shown in FIG. 5A, a plurality of engaged portions 7A and engaging portions 7B, that is, lock mechanisms 7, are provided.

  The pair of engaged portions 7A and the pair of engaging portions 7B are provided at symmetrical positions in the horizontal direction. The pair of engaged portions 7A and the pair of engaging portions 7B have a symmetrical relationship including the shape. Therefore, details of the lock mechanism 7 will be described below by taking the engaging portion 7B and the engaged portion 7A positioned on the right side in FIG.

  As shown in FIG. 4B, the engaged portion 7 </ b> A is provided on the shoji 5. When the engaging portion 7B is engaged with the engaged portion 7A, the closed state is maintained. As shown in FIG. 4A, the engaged portion 7A is a cylindrical or columnar portion, and is fixed to the frame portion 5C of the shoji 5 via the stay member 5D.

  The stay member 5D is fixed to a portion of the frame portion 5C that is separated from the swing center axis L1 and parallel to the swing center axis L1, that is, the lower end side of the frame portion 5C. The stay member 5D is fixed to the frame portion 5C by a joining means such as welding or a mechanical fastening means such as a screw. The engaged portion 7A is also fixed to the stay member 5D in the same manner as the stay member 5D.

  The frame 3 is provided with a contact portion (not shown) that comes into contact with the frame portion 5C of the shoji 5 when the shoji 5 is in a closed state. An elastically deformable packing such as rubber is provided at a portion of the contact portion that comes into contact with the frame portion 5C.

  In the state where the engaging portion 7B and the engaged portion 7A are engaged, the packing is crushed and elastically deformed, and the contact surface pressure with the frame portion 5C is changed between the engaging portion 7B and the engaged portion 7A. Rises compared to before engaging.

  The engaging portion 7B can be displaced between the position shown in FIG. 5A and the position shown in FIG. The position shown in FIG. 5A is a position where the engaging portion 7B and the engaged portion 7A are engaged (hereinafter referred to as an engaging position). The positions shown in FIGS. 5B and 5C indicate positions where the engaging portions 7B are separated from the engaged portions 7A (hereinafter referred to as engaged positions).

  As shown in FIG. 4B, the engaging portion 7B can be displaced in a direction perpendicular to the protruding direction of the protruding engaged portion 7A. In the engaged position, the engaging portion 7B is hooked on the engaged portion 7A and engaged with the engaged portion 7A. The engaging portion 7B is a hook-shaped hole whose outer edge is formed in a substantially J shape.

  Specifically, the engaging portion 7B has a substantially U-shaped or semicircular arc portion 7C and a guiding portion 7D. The arc portion 7C comes into contact with the outer peripheral surface of the engaged portion 7A when the engaging portion 7B and the engaged portion 7A are engaged, that is, in the state shown in FIG. 4B. Engage with 7A.

  The guiding portion 7D guides the engaged portion 7A to the arc portion 7C when the engaging portion 7B is displaced from the engaged position toward the engaged position. When the engaging portion 7B and the engaged portion 7A are engaged, the frame portion 5C of the shoji 5 and the packing are elastically deformed, and the gap between the shoji 5 and the frame 3 is sealed.

  As shown in FIG. 4A, the displacement direction of the metal displacement member 7E provided with the engaging portion 7B is guided by the guide rail 8. The guide rail 8 extends in a direction orthogonal to the protruding direction of the engaged portion 7A (in this embodiment, a direction along the horizontal frame portion 3B) and is fixed to the frame body 3 or its periphery.

  The guide rail 8 has a metal rail body 8B and a resin cable guide 8C. The rail body 8B is in sliding contact with the resin shoe 8A integrated with the displacement member 7E (hereinafter also referred to as sliding contact).

  For this reason, the displacement member 7E can be displaced smoothly without rattling. The cable guide 8C is a protective member that covers the first transmission member 15A and is capable of sliding contact with the first transmission member 15A.

  The cable guide 8C is a resin-made member formed in a cylindrical shape, and has a slit-shaped cutout hole extending along the longitudinal direction thereof. The cable guide 8C is integrated with the rail body 8B by an insert molding method or the like.

  15 A of 1st transmission members are connected with the displacement member 7E via the connection member 7F, and are displaced integrally with the displacement member 7E. And 15 A of 1st transmission members which concern on this embodiment are comprised with the geared cable which wound the meshing wire helically around the core wire which twisted together the several strand, and made it worm shape.

  As shown in FIG. 1, an operating member 9 is provided on the frame body 3 or the surrounding wall of the frame body 3. The actuating member 9 is displaced with respect to the frame 3 to displace the shoji 5 located in the open state to the closed state side.

  That is, the operation member 9 is provided on both sides of the shoji 5. As shown in FIGS. 2, 3 (a) and 3 (b), the pair of actuating members 9 can be displaced in parallel along the vertical frame portion 3 </ b> A of the frame 3. For this reason, each of the pair of vertical frame portions 3A is provided with a guide rail 11 that extends parallel to the vertical frame portion 3A and guides the displacement of the operating member 9.

  The guide rail 11 has the same structure as the guide rail 8 as shown in FIG. That is, it has a metal rail body 11B and a resin cable guide 11C. The guide rail 11 is fixed to the vertical frame portion 3A via a bracket 11A.

  The rail body 11 </ b> B is in sliding contact with a resin shoe 9 </ b> B integrated with the operating member 9. For this reason, the operation member 9 can be displaced smoothly without rattling. The cable guide 11C is a protective member that covers the second transmission member 15B and is slidable in contact with the second transmission member 15B.

  The second transmission member 15B is connected to the actuating member 9 via a connecting member 9C. For this reason, the second transmission member 15 </ b> B is displaced integrally with the operation member 9. The second transmission member 15B is also composed of a geared cable.

  As shown in FIG. 1, the first transmission member 15A and the second transmission member 15B are integrated into a single geared cable. That is, one longitudinal side of the one geared cable (hereinafter referred to as the transmission member 15) functions as the first transmission member 15A, and the other end functions as the second transmission member 15B.

  As shown in FIG. 2, the actuating member 9 has a sliding contact portion 9 </ b> A that is in sliding contact with the cam portion 13 provided in the shoji 5. The slidable contact portion 9A is a member in which at least a portion in sliding contact with the cam portion 13 has a curved surface shape. The sliding contact portion 9A according to the present embodiment is configured by a columnar or cylindrical protrusion.

  The cam portion 13 converts the displacement operation of the operation member 9 into the displacement operation of the shoji 5 by sliding contact with the sliding contact portion 9A. Specifically, the cam portion 13 according to the present embodiment includes a first slidable contact portion 13A and a second slidable contact portion 13B that are in sliding contact with the sliding contact portion 9A.

  The first sliding contact portion 13A is a surface that is inclined with respect to the displacement direction of the operating member 9, and is an inclined surface having the following inclination direction. That is, the first sliding contact portion 13A generates a component force that displaces the shoji 5 toward the closed state when the operating member 9 is displaced in the “closing direction” at the contact portion with the sliding contact portion 9A. Inclined in the direction.

  “Closed direction” refers to a direction in which the actuating member 9 is displaced when the shoji 5 positioned in the open state is displaced toward the closed state. Note that the “closing direction” according to the present embodiment is a direction from the lower side to the upper side. The direction opposite to the “closing direction” is referred to as the “opening direction”.

  The second sliding contact portion 13 </ b> B is a surface that is substantially parallel to the displacement direction of the actuating member 9 when the shoji 5 is in a closed state. Note that the first sliding contact portion 13A is inclined so as to approach the indoor side toward the upper side when the shoji 5 is in the closed state.

  Therefore, when the actuating member 9 is displaced in the closing direction, that is, from the lower side to the upper side, as shown in FIG. 3A, the contact portion between the first sliding contact portion 13A and the sliding contact portion 9A is not closed. A force F1 for displacing the shoji 5 is generated on the closed side.

  That is, when the operation member 9 is displaced in the closing direction, the cam portion 13 converts the displacement operation of the operation member 9 into the displacement operation of the shoji 5 while being in sliding contact with the sliding contact portion 9A. The force F <b> 1 is a component force of the force Fo that the operating member 9 acts on the cam portion 13.

  When the actuating member 9 is displaced in the opening direction, that is, from the upper side to the lower side, the forces Fo and F1 disappear. For this reason, the shoji 5 is displaced in the direction of opening the window opening 1A by the moment around the swing axis 5A due to gravity acting on the weight portion 5B.

  As shown in FIG. 3B, when the sliding contact portion 9 </ b> A is separated from the cam portion 13, the shoji 5 is displaced until it comes into contact with the contact portion 3 </ b> C provided on the frame body 3. That is, the contact portion 3 </ b> C regulates the maximum amount of displacement of the shoji 5 relative to the frame body 3 by contacting the abutted portion 5 </ b> E provided on the shoji 5.

  The contacted portion 5E according to the present embodiment is provided in the frame portion 5C of the shoji 5. The actuating member 9 is provided with a restricting portion 9D. The restricting portion 9D restricts the contact portion 3C and the contacted portion 5E from separating.

  That is, the restricting portion 9 </ b> D is disposed on the opposite side of the sliding contact portion 9 </ b> A across the cam portion 13 in the displacement direction of the operating member 9. Then, when the regulating portion 9D comes into contact with the regulated portion 5F provided on the shoji 5 from the side opposite to the sliding contact portion 9A, the separation between the abutting portion 3C and the abutted portion 5E is regulated.

  The restricted portion 5 </ b> F according to the present embodiment is provided in the cam portion 13. Specifically, the regulated portion 5F is provided on the back surface of the second sliding contact portion 13B. The cam portion 13 according to the present embodiment is a plate-like bracket provided with at least a first sliding contact portion 13A and a second sliding contact portion 13B. And the said bracket, ie, the cam part 13, is being fixed to the frame part 5C of the shoji 5, etc. with mechanical fastening means, such as a screw.

  As shown in FIG. 1, the pair of transmission members 15 mesh with the first gear 15 </ b> C having a worm wheel shape at one end in the longitudinal direction. For this reason, when the first gear 15C rotates, the pair of transmission members 15, that is, the pair of first transmission members 15A and the pair of second transmission members 15B are mechanically displaced in synchronism with each other and mechanically coupled thereto. The operating member 9 and the engaging portion 7B are displaced in conjunction with each other.

  The power generator 17 generates rotational power. The rotational power generated by the power generation unit 17 is transmitted to the transmission member 15 via the third transmission member 15D and the like. The third transmission member 15D is also composed of a geared cable.

  The power transmitted through the third transmission member 15D is transmitted to the second gear 15E. When the second gear 15E rotates, the first gear 15C rotates in synchronism, so that the power generated by the power generating unit 17 is transmitted to the engaging unit 7B and the operating member 9.

  The first gear 15C and the second gear 15E are integrated in a state where they are coaxially arranged, and are housed in a gear box 15F. Similarly to the transmission member 15, the third transmission member 15D is housed in the cable guide 15G shown in FIG.

2. Operation of Window Opening / Closing Device The power generating unit 17 according to the present embodiment generates power by an electric motor. The operation panel 17A shown in FIG. 1 includes a first operation unit 17B to a third operation unit 17D that instructs operation of the power generation unit 17, that is, rotation and stop of the electric motor.

<Closed state>
When the first operating portion 17B is operated when the window opening 1A is open, that is, when the shoji 5 is in the state shown in FIG. 3A or 3B, the power is transmitted via the transmission member 15. It acts on the actuating member 9 and the displacement member 7E.

  The actuating member 9, that is, the sliding contact portion 9A, is displaced from the lower side to the upper side while being in sliding contact with the cam portion 13 (first sliding contact portion 13A). Thereby, the parallel displacement of the operation member 9 is converted into the swing displacement of the shoji 5, and the shoji 5 is displaced in the direction of closing the window opening 1A.

  When the window opening 1A is in an open state, the engaging portion 7B is separated from the engaged portion 7A as shown in FIG. 5B or 5C. The displacement member 7E obtains power from the transmission member 15 (first transmission member 15A) and is displaced to the position shown in FIG. For this reason, the engaging part 7B and the engaged part 7A are engaged, and the closed state is maintained by restricting the sliding element 5 from being displaced with respect to the frame 3.

  The electric motor is stopped by any of the following methods. (A) When a first predetermined time elapses from when the first operating unit 17B is operated to start energization of the electric motor, (b) the value of the current flowing through the electric motor is predetermined. When the predetermined current value is exceeded, (c) the energization of the electric motor is stopped when it is detected by the detection unit (not shown) that the window opening 1A is closed.

  Therefore, when the first operating portion 17B is operated in a state where the shoji 5 is displaced with respect to the frame 3 and closed, or when the shoji 5 is displaced with respect to the frame 3, The electric motor stops when it is closed.

<Ventilation state>
When the window opening 1A is closed, that is, when the shoji 5 is in the state shown in FIG. 2, when the second operation portion 17C is operated, power acts on the operating member 9 and the displacement member 7E via the transmission member 15. To do.

  Since the actuating member 9 is displaced from the upper side to the lower side, as shown in FIG. 3A, the shoji 5 is displaced in a direction to open the window opening 1A by a moment due to gravity acting on the weight part 5B. In the ventilation state, when the sliding contact portion 9A comes into contact with the cam portion 13, the maximum displacement amount of the shoji 5 is regulated.

  When the window opening 1A is in the closed state, the engaging portion 7B is engaged with the engaged portion 7A as shown in FIG. The displacement member 7E obtains power from the transmission member 15 (first transmission member 15A) and is displaced to the position shown in FIG. For this reason, the engaging portion 7 </ b> B and the engaged portion 7 </ b> A are separated from each other, and the shoji 5 can be displaced with respect to the frame 3.

  When the second operating portion 17C is operated in the smoke emission state shown in FIG. 3B, that is, when the regulating portion 9D and the regulated portion 5F are in contact with each other, the actuating member 9 is shown in FIG. Displacement to the position shown in (a). For this reason, since the operating member 9 is displaced upward while the sliding contact portion 9A and the cam portion 13 (first sliding contact portion 13A) are in contact with each other, the shoji 5 has the window opening 1A in the smoke exhaust state described later. Displace to close side.

<Smoke emission state>
When the third operating portion 17D is operated while the window opening 1A is closed or in a ventilated state, power is applied to the operating member 9 and the displacement member 7E via the transmission member 15.

  Since the operating member 9 is displaced from the upper side to the position shown in FIG. 3B, the shoji 5 is in the maximum displaced state by contacting the contact portion 3C and the contacted portion 5E, and the restricting portion 9D. The regulated portion 5F comes into contact. For this reason, separation of the contact portion 3C and the contacted portion 5E is restricted.

  In the present embodiment, a detection unit (not shown) for detecting the position of the shoji 5 is provided. Whether the shoji 5 is located in the closed state, the ventilation state, or the smoke emission state is determined using a signal from the detection unit.

3. Features of Window Opening and Closing Device According to this Embodiment In this embodiment, when power is generated by the power generation unit 17, the power is transmitted to the engaging portion 7 </ b> B and the operation member 9 via the transmission member 15. That is, in the present embodiment, the engaging portion 7B and the operating member 9 operate mechanically in conjunction with each other.

  Therefore, in this embodiment, it becomes possible to interlock | cooperate with the action | operation member 9 and the lock mechanism 7 with a simple structure. And the engaging part 7B and the action | operation member 9 which operate | move interlocking mechanically do not require an electrical control part.

  By the way, when the separation distance between the actuating member 9 and the engaging portion 7B is large, it is closed while increasing the force for holding the closed state, that is, the force necessary for opening the shoji 5 in the closed state. This is advantageous from the viewpoint of reducing the force acting on the frame 3 in the state.

  Therefore, in the present embodiment, the engaging portion 7B is provided on the lower end side of the frame body 3, and the sliding contact portion 9A is positioned above the swing shaft 5A in a state where the window opening 1A is closed. The operating member 9 and the lock mechanism 7 are interlocked with a simple configuration while ensuring the above advantages.

  In the present embodiment, the actuating member 9 can be displaced in parallel along the frame body 3, and further, the sliding member 5 is in sliding contact with the actuating member 9, whereby the actuating member 9 is displaced by the displacement of the shoji 5. It is characterized in that a cam portion 13 for converting into operation is provided.

  Thereby, in this embodiment, when the operation member 9 is displaced, it can suppress that the operation member 9 protrudes and displaces greatly indoors. Therefore, it can suppress that the designability of a window opening and closing apparatus is impaired remarkably.

  Incidentally, in the window opening and closing apparatus described in Patent Document 1, the shoji is displaced in a closing direction by a restriction arm that is swingably assembled to the frame. For this reason, when the restricting arm swings, the restricting arm largely protrudes and displaces indoors, so that the design of the window opening / closing device is significantly impaired.
