[0008] The embodiments of the present invention will be described below with reference to the drawings. Figures 1 to 3 show one embodiment of the opening device of the present invention. This opening device is applied to inward-tilting windows for buildings. As shown in Figures 2 and 3, this opening device comprises a frame 1 attached to the opening in the building structure, a sliding door 9 attached to the frame 1 so as to be able to be opened and closed by tilting inward, and a screen door 10 attached to the frame 1 so as to extend outward.

[0009] As shown in Figures 2 and 3, frame 1 is constructed by framing an upper frame 11, a lower frame 12, and left and right vertical frames 13, 13, all made of extruded aluminum alloy profiles. As shown in Figure 2, the upper frame 11 has a hanging piece 14 at its outdoor end. As shown in Figure 3, the vertical frames 13 have a protruding piece 15 at their outdoor end that projects inward, and a sealing material holder 16 is provided at the tip of the protruding piece 15. The sealing material 17 held in the sealing material holder 16 is in contact with the outdoor surface of the sash 9.

[0010] As shown in Figures 2 and 3, the shoji screen 9 is constructed by assembling an upper frame 18, a lower frame 19, and left and right vertical frames 20, 20, all made of extruded aluminum alloy profiles, and installing double-glazed glass 21 inside. As shown in Figure 2, the shoji screen 9 is rotatably connected when a hinge portion 22 provided on the lower interior side of the lower frame 19 engages with a hinge fitting 23 attached to the lower frame 12. A latch 24 is also attached to the interior side of the upper frame 18 of the shoji screen 9, and the closed shoji screen 9 is locked when the latch 24 engages with a latch receiver 25 attached to the upper frame 11.

[0011] As shown in Figures 2, 3, and 4, the screen door 10 is formed by framing an upper frame 26, a lower frame 27, and left and right vertical frames 28, 28 made of extruded aluminum alloy profiles to form a rectangular frame body 2, and stretching a mesh 29 over the opening of the frame body 2. As shown in Figure 1, the upper frame 26 of the screen door 10 has an outer perimeter wall 30 that extends inward, and a locking portion 8 is provided protruding upward from the indoor end of the wall, and the locking portion 8 locks to the indoor side of the inner perimeter edge 4 of the hanging piece 14 formed on the outdoor end of the upper frame 11. As shown in Figure 2, the bottom frame 27 of the screen door 10 has rubber fins 31 extending inward from the outer edge of the interior side, with the interior end of the fins 31 contacting the upper surface of the bottom frame 12, thereby sealing the gap between the bottom frame 27 of the screen door 10 and the bottom frame 12. As shown in Figure 3, the vertical frame 28 of the screen door 10 has an outer perimeter wall 32 that extends inward, and its indoor end is located close to the inner perimeter of the tip of the protruding piece 15 formed on the outdoor end of the vertical frame 13.

[0012] As shown in Figures 4 and 5, a connecting fitting 33 is provided at the lower end of the vertical frame 28 of the screen door 10. The connecting fitting 33 connects the lower end of the vertical frame 28 to the longitudinal end of the bottom frame 27, and also closes the gap between the outer periphery wall 32 of the vertical frame 28 and the fin piece 31 of the bottom frame 27. The connecting fitting 33 has a locking portion 35 that protrudes laterally toward the outer periphery and a locking portion 36 that protrudes downward. As shown in Figure 3, the locking portion 35 that protrudes laterally toward the outer periphery locks onto the indoor side of the tight material holder 16 of the vertical frame 13, and as shown in Figure 2, the locking portion 36 that protrudes downward locks onto the outdoor side surface of the bottom frame 12.

[0013] As shown in Figures 1 and 4, a frame fixing device 3 is provided in the middle of the longitudinal direction of the upper frame 26 of the screen door 10. The frame fixing device 3 consists of a leaf spring 5 attached to the outer peripheral side of the outer peripheral wall 30 of the upper frame 26, and a movable body 37 provided continuously with the leaf spring 5 on the inner peripheral side of the indoor end of the leaf spring 5. As shown in Figures 1 and 8, the leaf spring 5 has a mounting portion 40 that abuts against a recess 38 formed on the outdoor side of the outer-circumferential wall 30 of the upper frame 26 and is fixed from the outer side with a screw 39, an inclined portion 41 that extends outward from the outdoor end of the mounting portion 40 toward the indoor side, and a hanging portion 42 that hangs down from the indoor end of the inclined portion 41. An insertion hole 43 for the head of the screw 39 that attaches the mounting portion 40 to the upper frame 26 is formed at the outdoor side position of the inclined portion 41. The hanging portion 42 integrates the leaf spring 5 and the movable body 37 by being inserted into an insertion hole 44 formed on the upper surface of the movable body 37, and a retaining element 45 provided by cutting and bending the lower part of the hanging portion 42 engages with a hole 46 in the movable body 37, thereby holding the hanging portion 42 in place so that it does not come out of the movable body 37.

[0014] As shown in FIGS. 1 and 8, the movable body 37 is formed of a rigid resin in a substantially columnar shape, and is inserted into a square hole 47 (see FIG. 6) formed in the prospective wall 30 on the outer peripheral side of the upper frame 26 of the screen door 10, and is provided so as to be movable in the inner and outer circumferential directions. The upper surface 48 of the movable body 37 is inclined so as to be continuous with the inclined portion 41 of the leaf spring 5, and an insertion hole 44 for the hanging portion 42 of the leaf spring 5 is formed at a substantially central position in the indoor-outdoor direction of the upper surface 48. At the corner portion between the upper surface 48 on the indoor side and the indoor side surface from the insertion hole 44, a contact portion 7 that contacts the outer side surface of the inner peripheral edge portion 4 of the hanging piece 14 formed at the outdoor side end portion of the upper frame 11 is provided. At the upper portion of the movable body 37, protrusions 49 are provided so as to project sideways on both the left and right sides, and the protrusions 49 prevent the movable body 37 from coming out to the inner peripheral side from the square hole 47 of the upper frame 26. The lower portion of the movable body 37 becomes an operation portion 6 that protrudes to the inner peripheral side of the prospective wall 30 through the square hole 47 of the upper frame 26. The operation portion 6 is formed with constricted portions 50 on the left and right side surfaces (see FIG. 8) to have a shape that is easy to grip with fingers. On the outdoor side surface and the indoor side surface of the operation portion 6, retaining portions 51a and 51b are formed that engage with the lower surface of the prospective wall 30 around the square hole 47 of the upper frame 26 to prevent the movable body 37 from coming out to the outer peripheral side from the square hole 47. The outdoor retaining portion 51a is formed of a claw that is elastically deformable in the indoor-outdoor direction.

[0015] Next, the procedure for attaching the frame fixture 3 to the upper frame 26 of the screen door 10 will be described. The frame fixture 3 inserts the hanging portion 42 of the leaf spring 5 into the insertion hole 44 of the movable body 37 to integrally unite the leaf spring 5 and the movable body 37 in advance. Then, as shown in Fig. 6(a), insert the lower part (operation part 6) of the movable body 37 into the square hole 47 of the upper frame 26 from above. At this time, the outdoor-side retaining part 51a elastically deform to the indoor side. When the movable body 37 is inserted up to approximately the central position of the vertical dimension of the movable body 37, as shown in Fig. 6(b), the outdoor-side retaining part 51a returns and locks to the lower surface of the expected wall 30, and the movable body 37 is prevented from coming out of the square hole 47 by the outdoor-side and indoor-side retaining parts 51a, 51b. Also at this time, the mounting part 40 of the leaf spring 5 is pushed by the upper frame 26 and bends upward, so that the angle between the mounting part 40 and the inclined part 41 of the leaf spring 5 becomes slightly smaller than the state before mounting, whereby the movable body 37 is always biased upward. After that, as shown in Fig. 6(b), when the mounting part 40 of the leaf spring 5 is screwed to the upper frame 26 with the screw 39 from above, as shown in Fig. 6(c), the frame fixture 3 is attached to the upper frame 26 of the screen door 10.

[0016] Next, the procedure for attaching the screen door 10 to the frame 1 will be described. First, as shown in Fig. 7(a), after tilting the shoji 9 indoors to open it, tilt the screen door 10 indoors and insert it into the frame 1 from the indoor side. Lock the locking part 35 of the connecting fitting 33 provided at the lower end of the vertical frame 28 to the indoor side of the tight material holder 16 of the vertical frame 13, and then slide the screen door 10 downward along the vertical frame 13. When the screen door 10 is slid downward until the connecting fitting 33 abuts against the upper surface of the lower frame 12, as shown in Fig. 7(b), push the upper part of the screen door 10 to the outdoor side and rotate the screen door 10 to the outdoor side with the locking part 35 as a fulcrum. At this time, the inclined part 41 of the leaf spring 5 provided on the outer peripheral side of the upper frame 26 of the screen door 10 abuts against the inner peripheral side end of the hanging piece 14 provided at the outdoor side end of the upper frame 11 and is pushed to the inner peripheral side, so that the movable body 37 moves to the inner peripheral side. When the screen door 10 is rotated to a vertical position, as shown in Figure 7(c), the contact portion 7 of the movable body 37 passes over the inner peripheral edge 4 of the hanging piece 14 of the upper frame 11, and the movable body 37 slides outward due to the biasing force of the leaf spring 5, and the contact portion 7 of the movable body 37 comes into contact with the outdoor side surface of the inner peripheral edge 4 of the hanging piece 14 of the upper frame 11, and the contact portion 7 of the movable body 37 and the locking portion 8 provided on the upper frame 26 of the screen door 10 clamp the inner peripheral edge 4 of the upper frame 11, fixing the screen door 10 to the frame 1 in the position extended to the outside.

[0017] To remove the screen door 10, as shown in Figure 9, pinch the operating part 6 of the movable body 37 with your fingers and pull the movable body 37 downwards. This will move the contact part 7 of the movable body 37 inward from the inner end of the hanging piece 14 of the upper frame 11, allowing the screen door 10 to be tilted inward. Then, tilt the screen door 10 inward and pull it out of the frame 1 to the inside.

[0018] As described above, the opening device, as shown in Figure 1, comprises a frame 1, a frame body 2, and a frame body fixing device 3. The frame 1 has an inner peripheral edge 4 on the outdoor side, the frame body 2 is attached to the frame 1 with an extension on the outdoor side, and the frame body fixing device 3 has a leaf spring 5 attached to the outer circumference of the frame body 3 and inclined outward toward the indoor side, an operating part 6 provided on the indoor side of the frame body 3, which is continuous with the inner circumference of the leaf spring 5, and a contact part 7 that abuts against the outdoor surface of the frame 1. The inner peripheral edge 4 of the frame 1 is clamped between the contact part 7 and a locking part 8 provided on the frame body 3, so that the frame body 2 can be easily attached to the frame 1 from the indoor side, improving the workability of attaching the frame body 2. In other words, when the frame body 2 is placed into the frame 1 from the inside, the inclined portion 41 of the leaf spring 5 is pressed against the inner peripheral edge 4 of the frame 1, causing the movable body 37 to move inward. As a result, the contact portion 7 of the movable body 37 moves over the inner peripheral edge 4 of the frame 1. Once it moves over, the biasing force of the leaf spring 5 causes it to return to its original position, and the contact portion 7 of the movable body 37 and the locking portion 8 of the frame body 2 clamp the inner peripheral edge 4 of the frame 1, thereby fixing the frame body 2 to the frame 1 (see Figure 7). Thus, the frame body 2 can be easily fixed to the frame 1 simply by inserting it into the frame 1 from the inside. Since the contact portion 7 of the frame fixing device 3, which abuts the exterior side surface of the frame 1, is made of resin, it is possible to prevent scratches on the frame 1 when attaching or detaching the frame 2. The operating unit 6 has retaining parts 51a and 51b that prevent it from coming out of the through hole (square hole) 47 provided in the inner wall 30 of the frame 2, thus preventing the operating unit 6 from coming out of the through hole 47 of the frame 2 towards the outer periphery. Since the retaining portion 51a is formed of an elastically deformable claw, when the operating portion 6 is inserted into the through hole 47 of the frame 2, the retaining portion 51a elastically deforms, making it easy to insert, and once inserted, the retaining portion 51a returns to its original position to securely prevent it from coming loose. As shown in Figure 8, the leaf spring 5 has an insertion hole 43 for the head of the mounting screw 39 to the frame 2, so that the leaf spring 5 can be easily fixed to the frame 2 with the screw 39. As shown in Figure 8, the leaf spring 5 has its tip (hanging portion) 42 inserted into the movable body 37 and held in place by the retaining clip 45. Therefore, the leaf spring 5 can be easily and reliably integrated with the movable body 37 simply by inserting its tip 42 into the movable body 37. As shown in Figures 8 and 9, the operating part 6 is shaped to be grasped with the fingers, allowing for easy operation by pinching the operating part 6 with the fingers, thus improving the work efficiency when removing the frame body 2 from the frame 1. As shown in Figures 1 and 8, the movable body 37 has a projection 49 that prevents it from coming out to the inner circumference through the through hole (square hole) 47 provided in the inner wall 30 of the frame body 2. Therefore, when the movable body 37 is moved to the inner circumference by operating the operating unit 6 in order to remove the frame body 2, the movable body 37 can be prevented from coming out of the through hole 47. As shown in Figure 1, the operating unit 6 is installed by penetrating the recessed wall 30 of the frame 2, making it easy to install the operating unit 6, and the recessed wall 30 prevents rain, wind, insects, etc. from entering. Furthermore, when viewed from the interior side, only the operating unit 6 of the frame fixing device 3 is exposed, and the other parts are hidden by the recessed wall 30 of the frame 2, resulting in a clean and uncluttered interior design.

[0019] The present invention is not limited to the embodiments described above. The cross-sectional shape and material of the frame and stile can be changed as appropriate. Stile fasteners may be provided on the vertical stiles and the bottom stile. Multiple stile fasteners may be provided at intervals along the longitudinal direction of the stile. The leaf spring is not limited to one in which the inclined portion is straight, but may also have a shape that is curved and inclined, for example. The shape of the contact portion and operating portion of the stile fastener can be changed as appropriate, and for example, the contact portion may be formed integrally with the leaf spring. The locking portion of the stile may be formed from a piece-shaped component attached to the stile, and the gap between the stile and the frame may be sealed with a fin-like piece, similar to the bottom stile. The stile is not limited to those that constitute a screen door, but may also be used to stretch a screen or hold a panel, etc. [Explanation of symbols]
