Mode for Carrying Out the Invention

[0007] Hereinafter, embodiments will be described with reference to the drawings. FIGS. 1 to 3 show an embodiment of the opening device of the present invention. This opening device is applied to a sliding window for a house, and as shown in FIGS. 2 and 3, it includes a frame 6 attached to the building opening, and an outer shutter 7a and an inner shutter 7b that are provided to be openable and closable in a sliding manner within the frame 6.

[0008] As shown in FIGS. 2 and 3, the frame 6 is configured by surrounding the upper frame 8, the lower frame 9, and the left and right vertical frames 10 and 11 to form a four-sided frame assembly. The outer shutter 7a and the inner shutter 7b are configured by surrounding the upper frame 12, the lower frame 13, the door tip frame 14, and the mating frame 15 to form a four-sided frame assembly, and a double-layer glass 16 is fitted inside thereof. Each of the frames 12, 13, 14, and 15 has a glass opening 19 with a U-shaped cross-section that opens inward on the inner peripheral side, formed by an aluminum profile 17 located on the outdoor side and a resin profile 18 located on the indoor side. The double-layer glass 16 is held in the glass opening 19 via a glazing channel 55, resulting in a highly heat-insulating shutter. When the inner and outer shutters 7a and 7b are closed, as shown in FIG. 2, the outer shutter 7a is located on the left side when viewed from the indoor side, and the inner shutter 7b is located on the right side when viewed from the indoor side. The outer shutter 7a and the inner shutter 7b are locked with a crescent (not shown) provided on the mating frame 15.

[0009] As shown in FIG. 3, the upper frame 8 has a screen rail 20 that supports the upper part of a screen window (not shown) at the outdoor side end, an outer rail 21 that supports the upper part of the outer shutter 7a on the indoor side of the screen rail 20, and an inner rail 22 that supports the upper part of the inner shutter 7b on the indoor side of the outer rail 21. The upper frame 8 connects an outdoor-side member 23 and an indoor-side member 24 made of an aluminum alloy extrusion with a resin heat-insulating bridge member 25, and covers the inner peripheral side of the indoor-side member 24 with a resin cover 26, thereby blocking heat transfer in the indoor-outdoor direction and preventing dew condensation on the indoor side. The resin cover 26 integrally has an angle 28 that is screwed to the frame 27. Furthermore, the upper frame 8 has a resin outer heat transfer suppression member 29 attached to the space between the outer rail 21 and the inner rail 22, and a resin inner heat transfer suppression member 30 attached between the inner rail 22 and the angle 28. The outer heat transfer suppression member 29 and the inner heat transfer suppression member 30 narrow the gap between the upper frame 8 and the inner and outer sliding doors 7a, 7b, thereby further suppressing heat transfer in the indoor-outdoor direction.

[0010] The outer heat transfer suppression member 29 and the inner heat transfer suppression member 30 each have a hollow portion 31, and the walls 32 on the outdoor side and the indoor side of the hollow portion 31 are bent inward in a "く" shape. When the outer sliding door 7a and the inner sliding door 7b are detachably attached between the upper and lower frames 8, 9 with vertical joints, the hollow portions 31 of the outer heat transfer suppression member 29 and the inner heat transfer suppression member 30 are elastically deformed so as to be pushed by the upper ends of the sliding doors 7a, 7b and crushed in the vertical direction, so that the outer heat transfer suppression member 29 and the inner heat transfer suppression member 30 do not interfere with the attachment and detachment of the sliding doors 7a, 7b.

[0011] As shown in FIG. 3, the lower frame 9 connects an outdoor-side member 23 and an indoor-side member 24 made of an aluminum alloy extrusion with a resin heat-insulating bridge member 25, and attaches resin covers 33a, 33b between the outer rail 21 and the inner rail 22 and on the indoor side of the inner rail 22 to cover the inner peripheral sides of the outdoor-side member 23 and the indoor-side member 24, thereby providing heat insulation. Also, by attaching the resin covers 33a, 33b, the upper surface of the lower frame 9 is substantially flat.

[0012] As shown in FIG. 1, the door end frame 14 of the outer sliding door 7a is configured by engaging and connecting an aluminum profile 17 arranged on the outdoor side and a resin profile 18 arranged on the indoor side, and a hand-holding portion 34 is formed in a concave shape on the entire length in the longitudinal direction on the indoor side surface of the resin profile 18. In addition, the door end frame 14 is provided with a groove 36 that opens toward the outer peripheral side and swallows a protruding piece 35 protruding toward the inner peripheral side of the vertical frame 10. A plurality of resin attracting components 37 are provided at intervals in the vertical direction in the groove 36. A tight material 38 is provided on the outdoor side wall of the groove 36 facing the indoor side. When the outer shutter 7a is closed, the inclined surface 37a of the attracting component 37 contacts the protruding piece 35 of the vertical frame 10, so that the door end frame 14 is attracted toward the indoor side. Accordingly, the tight material 38 is pressed against the protruding piece 35 of the vertical frame 10, thereby maintaining the watertightness and airtightness between the vertical frame 10 and the door end frame 14 (the same applies to the inner shutter 7b side).

[0013] As shown in FIG. 1, the vertical frame 10 on the outer shutter 7a side located on the left when viewed from the indoor side is composed of a metal vertical frame 1 made of an aluminum profile, a resin vertical frame 2 made of a resin profile attached to the inner peripheral side of the metal vertical frame 1, and a resin vertical frame cover 3 attached to the inner peripheral side of the resin vertical frame 2. The metal vertical frame 1 has a protruding piece 35 that is swallowed by the groove 36 of the door end frame 14 of the outer shutter 7a, and locking portions 39a and 39b to which the resin vertical frame 2 is locked are formed to protrude toward the inner peripheral side at substantially the central position in the indoor-outdoor direction and the indoor side end portion.

[0014] As shown in FIG. 1, the resin vertical frame 2 is provided along the inner peripheral side surface of the metal vertical frame 1 and has a projected wall 4 that covers the inner peripheral side surface of the metal vertical frame 1, a finding wall 5 that extends from the indoor side end portion of the projected wall 4 toward the inner peripheral side, and a mounting piece 41 that extends from the indoor side end portion of the finding wall 5 toward the indoor side and is fixed to the frame 27 with screws 40. An engaging portion 42 with which the outdoor side portion of the resin vertical frame cover 3 engages at an outdoor side position is formed to protrude toward the inner peripheral side on the projected wall 4. The engaging portion 42 has a locking groove 43 on the indoor side at the base with the projected wall 4. An engaging portion 44 with which the indoor side portion of the resin vertical frame cover 3 engages is formed to protrude toward the outdoor side on the finding wall 5. The resin vertical frame 2 is locked to the locking portions 39a and 39b of the metal vertical frame 1 and attached, and is fastened together with the metal vertical frame 1 to the housing 46 with screws 45 from the inner peripheral side. As shown in FIG. 2, the resin vertical frame 2 covers the inner peripheral side surface of the metal vertical frame 1 in a range substantially the same as the range A in the projected direction where the inner shutter 7b is located.

[0015] As shown in Fig. 1, the resin vertical frame cover 3 is attached to the inner peripheral side of the resin vertical frame 2 so as to fill the space between the finding wall 5 of the resin vertical frame 1 and the door end frame 14 of the outer shutter 7a. The expected dimensions of the resin vertical frame cover 3 are substantially the same as the expected dimensions of the expected wall 4 of the resin vertical frame 2. Further, the position of the resin vertical frame cover 3 in the inner and outer peripheral directions of the inner peripheral side surface 47 is substantially the same as the position of the bottom wall 19a of the glass opening 19 of the door end frame 14 of the outer shutter 7a. As a result, in this opening device, the portion on the outer peripheral side of the bottom wall 19a of the glass opening 19 of the door end frame 14 as viewed from the indoor side is hidden by the resin vertical frame cover 3. Further, the inner peripheral side surface 47 of the resin vertical frame cover 3 is flush with the inner peripheral side surface of the attachment piece 41 of the resin vertical frame 2.

[0016] The resin vertical frame cover 3 engages the groove 48 formed at the outdoor side end with the engaging portion 42 on the outdoor side of the resin vertical frame 2 (more specifically, engages the protrusion 49 formed on the indoor side of the groove 48 with the locking groove 43 of the engaging portion 42). With the engaging portion 42 as a fulcrum, the resin vertical frame cover 3 is rotated to the outer peripheral side, and the claw piece 50 formed at the indoor side end is elastically engaged with the engaging portion 44 on the indoor side of the resin vertical frame 2, so that the resin vertical frame cover 3 is detachably attached to the resin vertical frame 2 from the inner peripheral side. When the resin vertical frame cover 3 is attached in this way, a plurality of hollow portions 54, 54,... are formed in the expected direction by the expected wall 4 of the resin vertical frame 2 and the resin vertical frame cover 3. Further, the screw 45 that fixes the resin vertical frame 2 to the housing 46 is hidden by the resin vertical frame cover 3.

[0017] The outdoor side portion 51a of the inner peripheral side wall 51 of the resin vertical frame cover 3 is rotatably connected to the shaft 52 provided on the indoor side. When opening the outer shutter 7a, the portion 51a is pushed with a finger and rotated to the outer peripheral side as shown by the two-dot chain line in Fig. 1, so that a finger can be hooked on the handle portion 34 of the door end frame 14 of the outer shutter 7a to open the outer shutter 7a. When the finger is released, the portion 51a returns to its original position by a spring (not shown).

[0018] As described above, this opening device attaches a resin vertical frame 2 to the inner peripheral side of the metal vertical frame 1 of the vertical frame 10 to cover the inner peripheral side surface of the metal vertical frame 1, and further attaches a resin vertical frame cover 3 to the inner peripheral side of the resin vertical frame 2 to fill the space between the finding wall 5 of the resin vertical frame 2 and the door end frame 14 of the outer shutter 7a. Thus, the heat transfer between the indoor and outdoor through the metal vertical frame 1 can be suppressed, and the heat transfer between the vertical frame 10 and the door end frame 14 of the outer shutter 7a and through the door end frame 14 can also be suppressed, so that the heat insulation performance can be improved. If the engaging portion 42 with which the resin vertical frame cover 3 engages is provided on the metal vertical frame 1, the indoor heat will be transmitted from the engaging portion to the metal vertical frame 1 and escape outdoors. However, in this opening device, since the engaging portion 42 with which the resin vertical frame cover 3 engages is provided on the resin vertical frame 2, the escape of indoor heat from the engaging portion 42 can be prevented. In addition, since the door end frame 14 of the outer shutter 7a is hidden by the resin vertical frame cover 3, the interior design and the viewability are improved.

[0019] As shown in FIG. 2, the door end frame of the inner shutter 7b is configured by engaging and connecting an aluminum profile 17 arranged on the outdoor side and a resin profile 18 arranged on the indoor side, and a handrail portion 53 protrudes indoors at the inner peripheral side end of the resin profile 18. The vertical frame 11 on the inner shutter 7b side located on the right side when viewed from the indoor side is composed of a metal vertical frame 1 and a resin vertical frame 2 attached to the inner peripheral side on the indoor side of the metal vertical frame 1. For the door end frame 14 of the inner shutter 7b, the portion on the outer peripheral side from the bottom wall 19a of the glass span 19 is hidden by the resin vertical frame 2 when viewed from the indoor side.

[0020] As described above, this opening device includes a metal vertical frame 1, a resin vertical frame 2, and a resin vertical frame cover 3. The resin vertical frame 2 has a finding wall 4 provided along the inner peripheral side surface of the metal vertical frame 1 to cover the inner peripheral side surface of the metal vertical frame 1, and a finding wall 5 extending from the indoor side end of the finding wall 4 toward the inner peripheral side. The resin vertical frame cover 3 is engaged and attached to the resin vertical frame 2 and covers the inner peripheral side of the resin vertical frame 2 (see FIG. 1), so that the heat insulation performance can be improved. The resin vertical frame 2 covers the inner peripheral side surface of the metal vertical frame 1 within a range in the expected direction that is substantially the same as the range A in the expected direction where the inner blind 7b is located (see Fig. 2), thereby effectively suppressing the transfer of heat between the indoors and outdoors through the metal vertical frame 1 and further improving the heat insulation performance. In this opening device, a plurality of hollow portions 54, 54,... are formed in the expected direction by the expected wall 4 of the resin vertical frame 2 and the resin vertical frame cover 3 (see Fig. 1). These hollow portions 54, 54,... suppress the transfer of heat between the indoors and outdoors, and the heat insulation performance can be further improved. Since the resin vertical frame cover 3 is engaged and attached to the outdoor engagement portion 42 and the indoor engagement portion 44 provided on the resin vertical frame 2 (see Fig. 1), the resin vertical frame cover 3 can be easily and stably attached to the resin vertical frame 2. By not providing the engagement portion of the resin vertical frame cover 3 on the metal vertical frame 1, it becomes difficult for indoor heat to transfer to the metal vertical frame 1, and the heat insulation performance can be improved. In this opening device, since the expected dimension of the resin vertical frame cover 3 is substantially the same as the expected dimension of the expected wall 4 of the resin vertical frame 2 (see Fig. 1), the heat insulation effect by the resin vertical frame 2 and the resin vertical frame cover 3 can be enhanced. Since the position of the resin vertical frame cover 3 in the inner and outer peripheral directions of the inner peripheral side surface 47 is substantially the same as the position of the bottom wall 19a of the glass clear width 19 of the outer blind 7a (see Fig. 1), the resin vertical frame cover 3 effectively suppresses the transfer of heat between the indoors and outdoors between the vertical frame 10 and the outer blind 7a and through the door head frame 14, and the heat insulation performance can be further improved.

[0021] The present invention is not limited to the embodiments described above. The cross-sectional shapes of the metal vertical frame, the resin vertical frame, and the resin vertical frame cover can be appropriately changed. The configuration and opening method of the blinds are not limited. The present invention can be applied not only to sliding windows but also to various opening devices such as single-slide windows, sliding-out windows, and hinged doors.
