As can be seen from FIG. 5, the angle members 13d and 14d are members having a substantially L-shaped cross section, and one piece is fixed to the pieces 13a and 14a via the other members so that the pieces are along the pieces 13a and 14a. Is done. The other piece extends inward in the direction of finding from the end portion on the indoor side in the prospective direction of the one piece.
The inward turning member rail grooves 90, 90 are rail grooves in which an inward turning member (not shown) slides, have a substantially U-shaped cross section, and extend vertically.

  As will be described later, the guide grooves 40 and 40 are grooves for guiding the movable shoji 30 and are formed so that the support members 38 and 38 included in the movable shoji 30 slide inside thereof. Therefore, the cross section is formed in a U-shape. Here, the opening portion of the U-shape is provided with pieces 40a, 40a,... Facing each other so as to narrow the opening, and pieces 40b, 40b,. ing.

  On the other hand, the longitudinal direction of the guide grooves 40, 40 is shown in FIGS. 3 and 4 show the guide groove 40 provided in the vertical frame 14 and will be described based on this. The same applies to the guide groove 40 provided in the vertical frame 13. The guide groove 40 includes a straight portion 41 and an inclined portion 42 as indicated by broken lines in FIGS. The straight portion 41 is disposed on the inner side in the prospective direction than the fixed shoji 20 and extends in the longitudinal direction of the vertical frame 14. The inclined portion 42 communicates with the end of the linear portion 41 on the lower horizontal frame 12 side, and extends so as to be inclined toward the lower frame 12 side on the side where the fixed shoji 20 is provided (outside the prospective direction). ing.

  The inclination angle θ (see FIG. 3) with respect to the vertical plane of the inclined portion 42 is not particularly limited, but is preferably in the range of 45 degrees to 65 degrees. When the inclination angle θ is too large, the force required to open the movable shoji 30 increases.

  The fixed shoji 20 functions as an upper shoji, and is constructed by assembling an upper rod 21, a lower rod 22, and vertical rods 23, 24 into a square shape, and mounting a panel (for example, a glass panel) 25 in the compartment. In this embodiment, as the panel 25, as shown in FIG. 3 and the like, a multilayer glass panel in which a spacer is sandwiched between two sheet glasses is illustrated. However, it is not limited to this, and single plate glass may be used. In the present embodiment, a multilayer glass panel is preferred from the viewpoint of improving heat insulation.

  The panel 25 is fixed so that the four ends thereof are inserted into the upper rod 21, the lower rod 22, and the vertical rods 23 and 24 through the glazing channel. And the fixed shoji 20 is fixed to the angle members 13d and 14d of the vertical frames 13 and 14 by the vertical rods 23 and 24 by the fixing members 26 and 26. As a result, the fixed shoji 20 is attached to the upper part inside the frame 10 with its position being fixed.

  The movable shoji 30 is configured by assembling an upper rod 31, a lower rod 32, and vertical rods 33, 34 into a square shape and mounting a panel (for example, a glass panel) 35 in the compartment. In the present embodiment, as the panel 35, as shown in FIG. 3 and the like, a multilayer glass panel in which a spacer is sandwiched between two sheet glasses is illustrated.

The panel 35 is fixed so that the four ends thereof are inserted into the upper rod 31, the lower rod 32, and the vertical rods 33 and 34 through the glazing channel. Here, as can be seen from FIG. 3 and the like, the upper collar 31 is provided with a handle portion 36 on the indoor side. As a result, the movable shoji 30 can be easily opened and closed by operating the handle portion 36 with a hand as will be described later. In addition, as clearly shown in FIG. 3, the upper collar 31 (the handle portion 36) is configured to cover the lower collar 22 of the fixed shoji 20 when viewed from the indoor side in a closed posture. By setting it as this form, while improving an external appearance, it becomes a structure excellent in watertightness, heat insulation, and crime prevention. That is, by covering the space between the fixed shoji 20 and the movable shoji 30 with the upper rod 31 (the pulling portion 36) in a closed posture, water and heat can be prevented from entering and leaving to improve water tightness and heat insulation. Moreover, since it is difficult to insert a bar or the like, it is possible to improve crime prevention.
Further, as can be seen from FIG. 3, a lock member guide 31 a extending in the longitudinal direction and having a substantially L-shaped cross section is provided on the upper surface of the upper collar 31. The lock member guide 31a is a piece that engages and guides a sliding rod 76 (see FIGS. 6 to 8) of latches and lock members 70, 70 described later. One piece of the L-shaped cross section of the lock member guide 31a is erected in the direction of finding from the upper surface of the collar 31, and the other piece extends from the front end to the inside of the prospective direction.

Furthermore, as can be seen from FIGS. 2 to 5, support members 38, 38 are attached to the left and right ends of the lower arm 32 of the movable shoji 30 so as to protrude outward in the finding direction. The support members 38, 38 have support portions 38a, 38a that are inserted into the guide grooves 40, 40 and move in the grooves. The support portion 38a is provided with annular grooves 38b and 38b. The annular grooves 38b and 38b have wires 61 drawn from balancers 60 and 60 provided in the upper portions of the vertical frames 13 and 14, respectively. , 61 are locked at one end (see FIG. 2).
Accordingly, the movable shoji 30 is suspended by the balancers 60 and 60. The balancer 60 may be a balancer used for a normal raising / lowering window. For example, a spiral spring is provided in the balancer 60 to maintain the mass of the movable shoji 30 and to move the movable shoji 30 up and down with a small force. And it is comprised so that it can be made to stop at arbitrary heights. Although the example which provided the balancers 60 and 60 in the vertical frames 13 and 14 was shown in this embodiment, it is not limited to this, You may arrange | position to the upper frame 11. FIG.

  Next, the latch / lock devices 70 will be described. The figure for demonstrating in FIGS. 6-8 was shown. 6 is a view showing the latch / lock device 70 arranged on the vertical frame 13 side on the upper surface of the upper collar 31 in the sectional view taken along the line VI-VI in FIG. In FIG. 6, the upper side of the paper represents the outdoor side and the lower side of the paper represents the indoor side. FIG. 7 is a perspective view of the latch / lock device 70. FIG. 8 is a plan view of the latch / lock device 70 (FIG. 8A) and FIG. 8A viewed from the direction of arrow VIII (left side view, FIG. 8B).

The latch / lock device 70 includes a base 71, a latch member 72, and a lock device 75.
The base 71 is a member that is the basis of the latch / lock device 70. That is, the latch / lock device 70 is formed by arranging the latch member 72 and the lock device 75 on the base 71. Here, the base 71 has a plate-like portion 71a that is substantially plate-like and an operation member attachment portion 71b to which a lock operation member 77 described later is slidably attached.

The latch member 72 is a plate-like member having one direction as a longitudinal direction, and one end side in the longitudinal direction is formed larger than the other, and the end face of the tip is formed in many faces. Specifically, the surface 72a orthogonal to the longitudinal direction, the surfaces 72b and 72c which are disposed at both ends of the surface 72a and are inclined to the other end in the longitudinal direction, and the respective ends of the surfaces 72b and 72c further extend in the longitudinal direction. And surfaces 72f and 72g extending in the longitudinal direction so as to be substantially orthogonal to the ends of the surfaces 72d and 72e. With such a configuration, a so-called bi-directional latch can be formed, and the movable shoji can be appropriately moved in the raising / lowering window in which the shoji is closed in a flush position as will be described later.
Further, the latch member 72 includes an elastic member 73 that urges the latch member 72 in a direction (longitudinal direction) orthogonal to the surface 72c.

  The lock device 75 includes a slide rod 76, a lock operation member 77, and a connecting member 78. The sliding rod 76 is a rod-shaped member, and has a substantially U-shaped cross section as can be seen from FIG. The lock operating member 77 is a member provided for an operator's operation, and is connected to the sliding bar 76 via a bar-like connecting member 78.

  The above-described members are combined as follows to constitute the latch / lock device 70. That is, the latch member 72 is disposed on one surface side of the plate-like portion 71 a of the base 71. At that time, as shown in FIGS. 6 to 8, the end portions on which the surfaces 72 a to 72 g are arranged protrude from the base 71. Further, one end of the elastic member 73 is fixed to the base 71 and the other end is fixed to the latch member 72, and the surfaces 72a to 72g of the latch member are urged so as to change the protruding amount with respect to the base 71.

On the other hand, with respect to the locking device 75, the sliding rod 76 is disposed on the other surface side of the plate-like portion 71 a of the base 71. At this time, the longitudinal direction of the sliding rod 76 is the same as the protruding direction of the latch member 72 described above, and the longitudinal axis of the latch member 72 and the axial line of the sliding rod 76 are viewed in plan view (view point in FIG. 8A). ). Further, as can be seen from FIG. 8 (b), one of the pieces having a U-shaped cross section of the sliding rod 76 is slidable while being engaged with the plate-like portion 71a.
The lock operation member 77 is slidably attached to the operation member attachment portion 71b. The sliding direction of the lock operating member 77 is the same direction as the longitudinal direction of the sliding rod 76. The connecting member 78 connects the sliding rod 76 and the lock operating member 77.

  Accordingly, the latch member 72 receives a predetermined force, and accordingly, the surface 72a to the surface 72g of the latch member can move so as to change the protruding amount with respect to the base body 71. On the other hand, in the locking device 75, the sliding rod can be moved in the longitudinal direction by sliding the locking operation member 77.

  The latch / lock device 70 configured as described above is disposed on each of both ends of the upper surface of the upper collar 31 of the movable shoji 30. At this time, as can be seen from FIG. 6, the surface 72 a to the surface 72 g of the latch member 72 of the latch / lock device 70 are attached so as to face the vertical frames 13 and 14. Further, as can be seen from FIG. 3, one piece of the U-shaped cross section of the sliding rod 76 is arranged to engage with the lock member guide 31 a of the upper collar 31. Thereby, the strength as a lock can be improved, and the reliability thereof can also be improved. Thereby, for example, even if the base 71 is formed of a resin material, it has sufficient strength as a locking device.

  Moreover, according to this embodiment, a latch and a locking device can be formed with one member. Therefore, it is not necessary to provide a so-called crescent lock and a latch separately, and the number of parts can be reduced. Also, the appearance is excellent.

  Next, the operation of the raising / lowering window 100 described above will be described. Here, the case where the raising / lowering window 100 is closed and the unlocking and the movable shoji 30 are opened from the locked position will be described as an example. 9 and 10 show the scene and the posture in the middle. FIG. 9 is a view from the same viewpoint as FIG. 3, and FIG. 10 is a view from the same viewpoint as FIG.

  As shown in FIG. 3, the movable shoji 30 is arranged in the same plane as the fixed shoji 20 below the fixed shoji 20 inside the frame 10 in the closed posture. At this time, as shown in FIG. 6, the latch / lock devices 70, 70 are arranged such that the surface 72 e of the latch member 72 is in contact with the piece of the rail groove 90 for the inward member. At this time, the latch member 72 presses the piece of the rail groove 90 for the inversion member by the elastic member 73 (see FIG. 8) provided therein. On the other hand, in the locking device 75, the sliding rod 76 is protruded greatly toward the vertical frames 13 and 14 by the locking operation member 77, and the tip thereof is engaged with the angle member 13d. Thereby, the movable shoji 30 cannot be moved, and is in a closed and locked state.

  From such a posture, the operator first moves the lock operating member 77 to the right in FIG. As a result, the sliding rod 76 is detached from the angle member 13d and unlocked. Then, the operator pulls down the handle portion 36 provided on the upper arm 31 of the movable shoji 30 to the indoor side so that the posture shown in FIGS. 9 and 10 is obtained. Thereby, the upper end part of the movable apparatus 30 is arrange | positioned at the guide groove 40 side. In such a pull-down, in the latch / locking device 70, the latch member 72 is shown in FIG. 10 beyond the position of the inward-turning member rail groove 90 and the piece 40b by the action of the elastic member 73 as a latch. Become posture. That is, the tip of the latch member 72 is disposed in the guide groove 40. Here, pieces 40a, 40a, 40b, and 40b are provided in the guide groove 40, and the surfaces 72d to 72g of the latch member 72 come into contact with and press the pieces. Then, when the piece 40b of the guide groove 40 comes into contact with the piece 72g of the latch member 72, it acts as a stopper so that the movable shoji 30 is unlikely to fall further indoors.

  After that, by pulling up the movable shoji 30 by placing the hand on the pulling portion 36, the support portion 38 and the latch member 72 move in the guide groove 40, and the movable shoji 30 is opened to the posture shown in FIGS. be able to.

  What is necessary is just to operate so that the said procedure may be traced when closing the movable shoji 30.

  In FIG. 11, the figure corresponded in FIG. 10 among the raising / lowering windows 200 concerning other embodiment was shown. In the raising / lowering window 200, the lock receiver 270 is provided in the guide groove 40 at a position corresponding to the position of the latch / lock device 70 when the movable shoji 30 is inclined to the indoor side (see FIG. 9). The The other parts are the same as those of the raising / lowering window 100 described above, and thus the same reference numerals are given and description thereof is omitted.

  As can be seen from FIG. 11, the lock receiver 270 is disposed in the guide groove 40 and can be engaged with the tip of the sliding rod 76 of the lock device. That is, with the movable shoji 30 tilted as shown in FIG. 9, the lock operating member 77 is operated to insert the sliding rod 76 into the guide groove 40 as shown in FIG. Then, the sliding rod 76 is prohibited from engaging the lock receiver 270 and pulling up the movable shoji 30. Therefore, the movable shoji 30 can be locked while maintaining its posture, and can be locked while allowing ventilation with a small gap between the lower end of the stationary shoji 20 and the upper end of the movable shoji 20.

  In FIG. 12, the figure corresponded in FIG. 10 among the raising / lowering windows 300 concerning further another embodiment was shown. In the raising / lowering window 300, a hole 372 a is provided on the opposite side of the latch member 372 of the latch / lock device 370 from the side on which the surface 72 a is provided. In addition, an engaging member 373 is disposed on the plate-like portion 71 a of the base 71. The other parts are the same as those of the raising / lowering window 100 described above, and thus the same reference numerals are given and description thereof is omitted.

  The engaging member 373 can be engaged with the hole 372a provided in the latch member 372. When engaged, the latch member 372 can be inhibited from moving. That is, as shown in FIG. 12B, when the latch plate engaging member 373 is engaged with the hole 372a of the latch member 372, the latch member 372 becomes the vertical frame 13 (the same applies to the vertical frame 14 side). The movement is prohibited in a posture that does not contact. Thereby, the movable shoji 30 can be further brought down indoors. For example, the outdoor side of the movable shoji 30 can be cleaned. According to this, since the latch member 372 does not contact the vertical frames 13 and 14, the movable shoji 30 can be brought down without using unnecessary force, and the indoor side surfaces of the vertical frames 13 and 14 are not damaged. .

In the raising and lowering windows described above, the fixed shoji is installed with the upper shoji fixed to the upper part of the frame.
