Embodiments for Carrying out the Invention

[0007] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The electric opening and closing body device 1 is, for example, an electric shutter. The electric opening and closing body device 1 is arranged in the opening 100 in a building. As shown in FIG. 1, a window 103 is provided in the opening 100.

[0008] The electric opening and closing body device 1 covers the outdoor side of the closed window 103 and protects the opening 100. The electric opening and closing body device 1 includes a frame portion 11, a shutter box 12, a slat curtain 13 as an opening and closing member, a winding shaft portion 14, a winding drive device 10, a transformer 7, an electrical wiring 8, and a power supply portion 9.

[0009] The power supply portion 9 is arranged on the wall surface 101 on the indoor side of the building. The power supply portion 9 has a plug-in port 9a that can be connected to a commercial power supply of AC100V for driving the electric opening and closing body device 1.

[0010] The frame part 11 is arranged along the periphery of the opening part 100 and fixed to the outer wall surface of the building. The shutter box 12 is arranged along the width direction above the frame part 11. The inside of the shutter box 12 is formed to be hollow. The slat curtain 13 is a planar material that can be opened and closed outside the opening part 100. The slat curtain 13 is configured to open and close the opening part 100 by being wound up in a roll shape or moving up and down so as to hang down. The slat curtain 13 is housed inside the shutter box 12 in a wound-up state.

[0011] The winding shaft part 14 is an elongated cylinder with a hollow interior that extends from one end to the other end of the shutter box 12. The end of the slat curtain 13 is fixed to the outside of the winding shaft part 14. When the winding shaft part 14 rotates, the slat curtain 13 is wound up or hung down from the winding shaft part 14. On one side of the inner end of the winding shaft part 14, a winding drive device 10 described later is arranged. On the other side of the inside of the winding shaft part 14, a spring set 141 is arranged.

[0012] The winding drive device 10 is a device that is fixed to the winding shaft part 14 and rotates the winding shaft part 14. The winding drive device 10 drives the slat curtain 13 by receiving power supply from the power supply part 9. As shown in FIG. 2, the winding drive device 10 has a case 2, a motor 3, and a substrate 4.

[0013] The case 2 is a substantially cylindrical member that forms the outer shape of the winding drive device 10. The case 2 has an upper case 21 and a lower case 22. The upper case 21 and the lower case 22 are each longitudinally elongated members that are substantially semi-circular in cross-sectional view and extend along the axial direction of the winding shaft part 14. The upper case 21 and the lower case 22 are connected to each other to form a cylindrical shape. The case 2 has sufficient strength to rotate the winding shaft part 14 to which the slat curtain 13 is connected and is made of metal.

[0014] The motor 3 drives and rotates the winding drive device 10 electrically. By rotating the winding drive device 10, the motor 3 winds up the slat curtain 13 or hangs it down to cover the opening 100 and drives it to move up and down. The motor 3 is housed inside the lower case 22. The motor 3 is connected to the gear 31 and is disposed on one end side of the case 2.

[0015] The substrate 4 is a control substrate that controls the winding drive device 10 to open and close the slat curtain 13 in response to instructions from a remote controller (not shown) by a user. The substrate 4 is disposed inside the lower case 22.

[0016] The transformer 7 is disposed outside the winding drive device 10 and is connected to the winding drive device 10. As shown in FIG. 1, the transformer 7 is composed of an adapter 70 integrated with a plug inserted into the insertion port 9a of the power supply unit 9 and is disposed indoors. The transformer 7 is a device that changes the voltage. In the present embodiment, the transformer 7 transforms the AC voltage, which is the power supplied from the power supply unit 9, into a DC voltage and transforms it lower, for example, to DC60V or less from AC100V.

[0017] As shown in FIG. 1, the electrical wiring 8 is a conductive wire that connects the winding drive device 10 and the power supply unit 9 and is also connected to the transformer 7. The electrical wiring 8 extends from the adapter 70 integrated with the transformer 7 and is formed to be connectable to the winding drive device 10. One end of the electrical wiring 8 is connected to the adapter 70 connected to the insertion port 9a of the power supply unit 9. The electrical wiring 8 is disposed along the edge of the opening 100, passes through the through-hole 102 to the inside of the outdoor shutter box 12, and the other end is connected to the end of the winding drive device 10 disposed inside the shutter box 12.

[0018] The 100V AC voltage supplied from the commercial power supply is transformed by a transformer 7 formed integrally with the plug and supplied to the winding drive device 10. The electrical wiring 8 is connected to a plurality of harnesses 81 arranged inside the case 2 of the winding drive device 10 and connected to various devices within the winding drive device 10. The winding drive device 10 is driven by a DC voltage.

[0019] According to the first embodiment, the following effects are achieved. The electric opening / closing body device 1 includes a winding drive device 10 that electrically drives a slat curtain 13 for opening and closing an opening 100 of a building, a power supply unit 9 that supplies power to the winding drive device 10, and a transformer 7 that is arranged outside the winding drive device 10 and steps down the voltage of the power supplied from the power supply unit 9. Since the transformer 7 is arranged outside the winding drive device 10, it is possible to use the power supplied at AC 100V in a transformed state. Therefore, anyone can perform the installation work of the electric opening / closing body device 1, eliminating the need to arrange a person with an electrician's qualification. Furthermore, since it is not necessary to arrange the transformer 7 inside the winding drive device 10, for example, on a substrate 4 or the like, the winding drive device 10 can be miniaturized. When the winding drive device 10 is miniaturized, the diameter of the winding shaft portion 14 of the electric opening / closing body device 1 becomes smaller, and it becomes possible to miniaturize the shutter box 12 that houses the winding shaft portion 14 and the slat curtain 13. Thus, it becomes possible to improve the appearance of the electric opening / closing body device 1.

[0020] According to the present embodiment, the transformer 7 transforms the AC voltage into a DC voltage. By transforming the AC voltage into a DC voltage, it becomes easier to control the speed of rotating the motor 3. By using an AC voltage, the noise generated during the driving of the motor 3 can be reduced. Thus, it becomes possible to provide an electric opening / closing body device 1 that is particularly suitable when the opening 100 partitions the interior and exterior like a window.

[0021] The present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure. In the first embodiment, the transformer 7 is integrated with a plug that is inserted into the insertion port 9a of the power supply unit 9. However, the transformer 7A may be configured by an external adapter and disposed inside the shutter box 12, like the electric opening and closing body device 1A of the second embodiment shown in FIG. 3.

[0022] The electrical wiring 8A extends from the winding drive device 10A and is connected to the transformer 7A. The electrical wiring 8A extends from the transformer 7A to the outside of the shutter box 12, is disposed along the outer wall surface near the periphery of the building opening 100, and is connected to the power supply unit 9A disposed on the outer wall surface. The transformer 7A transforms the AC voltage supplied from the commercial power supply into a DC voltage and supplies it to the winding drive device 10A via the electrical wiring 8A.

[0023] According to the second embodiment, when the power supply unit 9A is disposed on the outer wall surface of the building, the electric opening and closing body device 1A can be installed without providing a through hole in the building wall surface. In addition, the same effects as those of the first embodiment are achieved.

[0024] In the electric opening and closing body device 1B of the third embodiment shown in FIGS. 4 to 6, the winding drive device 10B is different from the first and second embodiments in that it further has an insulating sheet 5 and fixing means 6.

[0025] The substrate 4 is supported by a support member 61 of the fixing means 6 described later and is covered by the insulating sheet 5. A harness 81 connected to various devices is connected to the substrate 4. The substrate 4 has a substrate main body portion 41 and a charging portion 42.

[0026] The substrate main body portion 41 is a thin insulating plate and is a non-charging portion made of synthetic resin. The substrate main body portion 41 has a substantially rectangular shape, and its longitudinal direction is disposed along the longitudinal direction of the case 2. The substrate main body portion 41 forms the outer shape of the substrate 4.

[0027] The charging unit 42 is a conductive part that is charged during normal use, and includes conductor wirings arranged on the substrate main body 41 and metal parts to which electronic components are soldered. As shown in FIG. 5, the charging unit 42 has a leg part 421 that protrudes downward from the lower surface of the substrate main body 41. The leg part 421 is a part of the soldered metal part. The charging unit 42 is arranged at a predetermined distance D from the case 2. More specifically, the lower end of the leg part 421 in the charging unit 42 is arranged at least 2.5 mm away from the lower case 22. By the charging unit 42 being 2.5 mm or more away from the lower case 22, the metal case 2 and the charging unit 42 are insulated from each other.

[0028] The insulating sheet 5 is made of a non-conductive material and is a flexible thin plate. The insulating sheet 5 is formed in a cylindrical shape having an outer diameter that can be inserted into the case 2. The insulating sheet 5 covers the substrate 4 by having the substrate 4 arranged inside its cylindrical shape, and also covers the harness 81 arranged on the substrate 4 and the motor 3 arranged adjacent to the substrate 4. The insulating sheet 5 also covers the support member 61 of the fixing means 6 described later together with the substrate 4. In other words, inside the cylinder formed by the insulating sheet 5, the substrate 4, the motor 3, the support member 61, etc. are arranged. Since the insulating sheet 5 covers the substrate 4, the substrate 4 and the case 2 are additionally insulated from each other. As shown in FIG. 4, an opening 51 that is partially cut out is formed in the insulating sheet 5. The insulating sheet 5 may be made of, for example, polypropylene or polycarbonate.

[0029] The fixing means 6 is a member that fixes the case 2 and the substrate 4. The fixing means 6 is made of an insulating material and has a support member 61 and a screw 62.

[0030] As shown in FIG. 4, the support member 61 is composed of a vertically long thin plate along the longitudinal direction of the substrate 4. The support member 61 has a support member main body 611, a case contact part 612, and a support convex part 613. The support member 61 is made of resin, specifically plastic.

[0031] The support member main body portion 611 has a substantially rectangular shape in plan view and is disposed below the substrate main body portion 41. A part of the support member main body portion 611 is cut out so as not to interfere with the leg portion 421 of the charging portion 42 protruding from the lower surface of the substrate main body portion 41.

[0032] As shown in FIG. 6, the case contact portions 612 are disposed at both ends in the longitudinal direction and at substantially the central portion in the longitudinal direction of the support member main body portion 611 on the back surface of the support member main body portion 611 on the side opposite to the side where the substrate 4 is disposed. The case contact portions 612 are arcuate portions having a curved lower surface so as to follow the semi-circular curved portion of the lower case 22. The width of the case contact portion 612 is wider than the width of the support member main body portion 611 and protrudes from both ends in the width direction of the support member main body portion 611.

[0033] As shown in FIGS. 4 and 5, the support protrusion 613 is a protrusion protruding upward from the end of the case contact portion 612. The support protrusion 613 supports the lower side of the substrate main body portion 41. The support protrusion 613 is connected to and fixed to the substrate main body portion 41. By the support protrusion 613 supporting the substrate main body portion 41, a gap G is formed between the substrate main body portion 41 and the support member main body portion 611. The leg portion 421 of the charging portion 42 protrudes from the substrate main body portion 41 and is disposed in this gap G. Thereby, the leg portion 421 of the charging portion 42 and the support member main body portion 611 are not in direct contact. When the lengths of the leg portions 421 protruding from the charging portion 42 vary depending on the location, the substrate main body portion 41 does not tilt and the distance between the substrate main body portion 41 and the support member 61 is kept constant.

[0034] The screw 62 is a resin component that fixes the case 2 and the support member 61. The screw 62 penetrates and fixes the case 2, the insulating sheet 5, and the support member 61. Since the support member 61 is connected and fixed to the substrate 4, by connecting and fixing the case 2 and the support member 61 with the screw 62, the substrate 4 and the case 2 are connected and fixed via the insulating sheet 5. The screw 62 may be made of metal.

[0035] According to the third embodiment, since the charging portion 42 is disposed at a predetermined distance D from the case 2 and the substrate 4 is covered with the insulating sheet 5, the substrate 4 is doubly insulated from the case 2. As a result, the winding drive device 10B has a double insulation structure. Accordingly, it is not necessary to install an earth wire defined by the Electrical Appliance and Material Safety Act for the winding drive device 10B. Therefore, the construction of the winding drive device 10B becomes easy. In particular, workability is improved when the electric opening / closing body device 1B is installed as a retrofit, such as during renovation.

[0036] In the electric opening / closing body device 1C of the fourth embodiment shown in FIG. 7, the winding drive device 10C is different from the third embodiment in that it does not have a support member 61 and the case 2 and the substrate 4 are connected by a resin screw 62C.

[0037] The substrate main body portion 41 of the substrate 4 has a through hole 44 for fixing the screw 62C. The through hole 44 is disposed diagonally near a corner of the substrate main body portion 41. The lower case 22 has a mounting portion 221 in which a through hole 221a for fixing the screw 62C is formed. The mounting portion 221 is constituted by a protrusion protruding upward from the lower surface of the lower case 22 at a position corresponding to the through hole 44 of the substrate main body portion 41 in the lower case 22, and the upper surface thereof is formed flat. The through hole 221a of the mounting portion 221 is formed in the flat upper surface of the mounting portion 221.

[0038] The screw 62C is inserted through the through hole 44 of the substrate main body portion 41 and the through hole 221a in the mounting portion 221 of the lower case 22 to fix the substrate 4 and the lower case 22. The substrate 4 is covered with the insulating sheet 5, and the case 2 and the substrate 4 are disposed at a predetermined distance D apart. Therefore, even without the support member 61, the charging portion 42 of the substrate 4 and the lower case 22 are insulated only by fixing the substrate 4 and the lower case 22 with the screw 62C.

[0039] In the first to fourth embodiments, the electric opening / closing body device has been described as an electric shutter. The electric opening / closing body device 1 may be a roll screen, and the configuration and type are not limited as long as it is an electric opening / closing body device that opens and closes an opening / closing member by winding.
