Moreover, the rail grooves 90, 90 for the inward-turning members also function as portions that can be engaged with the latch members as will be described later.

  As will be described later, the guide grooves 40 and 40 are grooves for guiding the movable shoji 30, and support members 38 and 38 described later provided on the movable shoji 30 are formed so as to slide inside. Therefore, the cross section of the guide grooves 40, 40 is formed in a U shape. Here, of the U-shape, the opening portion 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 aspect of the longitudinal direction of the guide grooves 40 and 40 was represented to FIG.3 and FIG.4. 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 line portion 41 is disposed on the indoor side of the prospective direction from 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 is inclined toward the side on which the fixed shoji 20 is provided (that is, the outside in the prospective direction) and toward the lower frame 12 side. So as to extend.

  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 configuration of the raising / lowering window 100 will be described. As shown in FIG. 2 to FIG. 5, the fixed shoji 20 as the upper shoji is formed by assembling the upper eaves 21, the lower eaves 22, and the vertical eaves 23, 24 into a square, and a panel (for example, a glass panel) 25 in the compartment. Installed and configured. In the present 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 used. However, it is not limited to this, and a single plate glass panel may be used. In this embodiment, the multilayer glass panel was demonstrated as a preferable aspect from a 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. As shown in FIG. 5, the fixed shoji 20 has the vertical rods 23 and 24 fixed to the angle members 13 d and 14 d of the vertical frames 13 and 14 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. At this time, as can be seen from FIG. 3, the upper collar 21 is disposed so as to be inserted into the concave portion 11 a of the upper horizontal frame 11, and is fixed with water-tight airtightness.

  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 this embodiment, as the panel 35, as shown in FIG. 3 etc., the multilayer glass panel which pinched | interposed the spacer between two sheet glass is used. However, it is not limited to this, and a single plate glass panel may be used. In this embodiment, the multilayer glass panel was demonstrated as a preferable form from a viewpoint of improving heat insulation.

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. Further, as clearly shown in FIG. 3, the handle portion 36 of the upper collar 31 is formed so as to cover the lower collar 22 of the fixed shoji 20 when viewed from the indoor side in a closed posture. Thereby, 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 pulling portion 36 of the upper saddle 31 in a closed posture, water and heat can be prevented from entering and leaving, and water tightness and heat insulation are improved. Moreover, since it is difficult to insert a bar or the like from the outdoor side, 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 tip 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 so that the mass of the movable shoji 30 can be kept in balance and the movable shoji 30 can be moved up and down with a small force and can be stopped at an arbitrary height. Has been. 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 in 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 having a substantially horizontal plate shape and an operation member attaching 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 30 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, as can be seen from FIG. 8, the latch member 72 is provided with an elastic member 73 that urges the latch member 72 in a direction (longitudinal direction) orthogonal to the surface 72a.

  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 operation member 77 is a thin block-like member that is used for an operator's operation. The connecting member 78 is a rod-like member, and connects the lock operating member 77 and the sliding rod 76.

  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 that the protruding amount can be changed 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. 8B, 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 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 76 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 surfaces 72 a to 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.

According to this embodiment, the lock device 75 is arrange | positioned at the right-and-left both ends side of a shoji. Further, the lock operation member 77 which is the operation member can also suppress the protruding amount from the collar 31 to be small. Therefore, the influence on the appearance can be reduced.
Further, the lock operating member 77 is provided on the indoor-side finding surface of the collar 31 of the movable shoji 30 and is concealed so that it cannot be seen from the outdoor side. Thereby, the presence and position of the locking device cannot be known from the outside, and crime prevention can be improved.
Here, according to the present embodiment, the latch 72 and the lock device 75 can be formed as 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.

  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. FIGS. 9 and 10 are views showing postures in the middle of the scene, FIG. 9 is a view from the same viewpoint as FIG. 3, and FIG. 10 is a view from the same viewpoint as FIG.

  In the closed posture, the movable shoji 30 is arranged in the same plane as the fixed shoji 20 below the fixed shoji 20 inside the frame 10 as shown in FIG. At this time, as shown in FIG. 6, the latch / lock devices 70, 70 come into contact with the piece of the rail groove 90 for the inwardly turning member that functions as a portion where the surface 72 e of the latch member 72 can be engaged with the latch member. Are arranged as follows. Further, the latch member 72 presses the piece of the rail groove 90 for the inversion member by an elastic member 73 (see FIG. 8) provided therein. On the other hand, the locking device 75 has a sliding rod 76 projecting greatly toward the vertical frames 13 and 14, and its tip is engaged with an angle member 13d that functions as a portion that can be engaged with the sliding rod. 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 shoji 30 is arrange | positioned at the guide groove 40 side. In such a pull-down, the latch member 72 of the latch / lock device 70 is moved from the above-described position beyond the rail groove 90 for the inward-turning member and the piece 40b by the action of a latch by the elastic member 73 (see FIG. 8). The posture shown in FIG. 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 are in contact with and press the pieces 40a, 40a, 40b, and 40b. 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. The raising / lowering window 200 can be engaged with the sliding rod 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). A lock receiver 270 that functions as a simple member is provided. 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 the description thereof is omitted.

  As can be seen from FIG. 11, the lock receiver 270 is disposed in the guide groove 40, functions as a member that can be engaged with the slide bar, and can be engaged with the tip of the slide bar 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 the posture, and the ventilator can be ventilated with a slight gap in the expected direction between the lower end of the fixed shoji 20 and the upper end of the movable shoji 20. It becomes possible to do.

  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 372a is provided at the end of the latch member 372 of the latch / lock device 370 opposite to the side on which the surface 72a is provided. In addition, an engaging member 373 is disposed on the plate-like portion 71 a of the base 71. Since other parts are common to the above-described raising and lowering window 100, 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 (so-called “inside-down”). 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. .

  Here, an example of inward tilting using the raising / lowering window 300 has been described. However, in the above-described raising / lowering windows 100, 200, if the latch member is retracted while being pressed by hand, the inward tilting is possible. That is, the latch member also functions as a latch that allows and prohibits inward tilting.

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. However, the upper shoji is not limited to this, and the upper shoji can move up and down in the frame. May be. At this time, the upper shoji may be configured to move independently, or may be configured to move in conjunction with the movable shoji 30 described above.
Moreover, in the said embodiment, although the upper and lower shoji were provided in the frame fixed to a building, it is not limited to this. For example, the frame provided with the upper screen and the movable screen can be further opened and closed in a swing manner with respect to another frame fixed to the building.

  Although the present invention has been described in connection with the most practical and preferred embodiments at the present time, the present invention is not limited to the embodiments disclosed herein, The present invention can be changed as appropriate without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and the raising and lowering windows accompanying such changes should not be understood as being included in the technical scope of the present invention. Don't be.
