FIG. 2 is a side view showing a schematic configuration of a pleated screen as an electric shielding device according to an embodiment of the present invention, and a schematic configuration of a charging pole 14 according to the first embodiment. The electric shield device shown in FIG. 1 and FIG. 2 shows an electric pleated screen that moves up and down a shielding material as a representative example. However, the present invention is not limited to the electric pleated screen, and may be, for example, an electric horizontal blind, an electric raising curtain, or the like.

  First, in an electric pleated screen according to an embodiment shown in FIGS. 1A and 1B, a screen 6 capable of being bent in a zigzag shape from a head box 1 is suspended and supported, and a lower end of the screen 6 is a bottom rail 7. It is attached to the upper surface of. The head box 1 is fixed to a mounting surface such as a ceiling surface via a bracket 13.

  As shown in FIG. 2, a pitch holding cord 4 is suspended from the head box 1, and an annular holding portion 4 a is provided at regular intervals with respect to the pitch holding cord 4. Each holding part 4a inserts the lifting cord 3 penetrating the screen 6 and supports the screen 6 so that the folds of the screen 6 are regularly arranged.

  The take-up drum 51 is rotatably supported by each of the support members 5 disposed at appropriate places (in this example, two right and left places) in the head box 1. An obstacle detection stop device 52 is provided at one axial end of the winding drum 51.

  The upper end of the elevating cord 3 (in this example, a cord-like cord, but may be a tape-like elevating tape) is wound or rewindably attached to the winding drum 51, and the lower end of the elevating cord 3 is In the present example, it penetrates through the screen 6 and is attached to the bottom rail 7. The winding drum 51 is formed so that the diameter gradually decreases toward one side in the axial direction. In this example, the cord-shaped elevating cord 3 is spirally wound around the winding drum 51 sequentially. I have.

  The drive shaft 2 is inserted through the central axis of each of the winding drum 51 and the obstacle detection / stop device 52.

  One end of the drive shaft 2 is connected to an output shaft of the motor 9 via a drive shaft coupler 9a, and rotation of the output shaft of the motor 9 is transmitted to the drive shaft 2. Therefore, the bottom rail 7 can be moved up and down by rotating the drive shaft 2 with the driving force of the motor 9 and winding or rewinding the lifting cord 3 with the winding drum 51 based on the rotation of the drive shaft 2, Thus, the screen 6 can be moved up and down.

Although details will be described later with reference to FIG. 4, a pair of suction members 12 c is a metal plate provided on the charger 141 in order to stably support the charger 141 on the power storage surface 12 b of the charging mechanism unit 12. It is composed of a thin columnar magnet that attracts 141a by magnetic force. Thereby, the non-contact power supply to the rechargeable storage battery 11 can be stabilized.

  Hereinafter, the power supply pole 14 of each embodiment will be described in more detail.

(Feeding pole of Embodiment 1)
FIG. 2 illustrates a schematic configuration of the charging pole 14 according to the first embodiment. FIGS. 3A to 3D are perspective views, front views, and schematic diagrams respectively illustrating the schematic configuration of the charging pole 14 according to the first embodiment. It is a sectional side view and a rear view. FIG. 4 is a partial perspective view schematically showing a state in which the charger 141 using the charging pole 14 according to the first embodiment is held over the rechargeable storage battery 11 via the charging mechanism unit 12 to enable wireless charging. .

  First, referring to FIGS. 2 and 3, the charging pole 14 according to the first embodiment includes a charger 141, a rod 142, and a power supply unit 143.

  The charger 141 is formed of a rectangular parallelepiped synthetic resin material that accommodates a non-contact charger 144 (for example, a wireless charging coil based on the Qi standard). The non-contact charger 144 is capable of contactless power supply to the rechargeable battery 11 when the non-contact charger 144 is disposed to face the power storage portion 11a (see FIG. 4) of the rechargeable battery 11 via the power storage surface 12b of the charging mechanism unit 12. It is a functional part that performs.

  The rod-shaped body 142 is a hollow columnar synthetic resin material whose upper end is attached to substantially the center on the front side of the charger 141 and which is bent from the upper end and extends downward in a length that can be gripped by the operator. Is molded.

  The power supply section 143 is attached to a lower end of the rod-shaped body 142 and is formed of a cylindrical box-shaped synthetic resin material containing a power supply body 146 that supplies power to the non-contact charger 144. In other words, a power supply cord 145 that electrically connects one end to the non-contact charger 144 passes through the hollow portion of the rod 142, and the other end is connected to the power feeder 146. Note that the power supply cord 145 may be configured to be held along the rod-shaped body 142 instead of being inserted through the hollow portion thereof.

  As shown in FIGS. 2 and 4, the charger 141 of the charging pole 14 according to the first embodiment has a U-shaped support portion 12 a of the charging mechanism portion 12 exposed from the opening 1 a on the front side of the head box 1. It can be mounted. As shown in FIGS. 3D and 4, a pair of metal plates 141 a provided at both left and right ends on the rear side of the charger 141 (the side facing the charging mechanism section 12) is attached to the charging mechanism section. A pair of attracting members 12c provided on the magnet 12 can be attracted by magnetic force. As shown in FIG. 4, the power storage surface 12 b of the charging mechanism 12 is provided at a position corresponding to the power storage portion 11 a of the rechargeable storage battery 11. Power can be supplied.

  Thus, according to the charging pole 14 of the first embodiment, the charger 141 is stably opposed to and supported by the power storage surface 12b of the charging mechanism unit 12, and the wireless power supply to the rechargeable storage battery 11 by the charger 141 is stabilized. Can be done.

  In addition, according to the charging pole 14 of the first embodiment, since the charging pole can be stably supported by the charging mechanism unit 12, the operator can perform non-contact power supply to the rechargeable storage battery 11 by the charger 141. Even when the charger 141 is released while being hung on the support portion 12a of the charging mechanism 12, stable non-contact power supply can be maintained.

  Further, according to the charging pole 14 of the first embodiment, the mounting of the charging pole 14 with respect to the charging mechanism 12 may be removed during the operation of the electric shielding device, so that the appearance is improved and the design is improved.

  The power supply 146 that supplies power to the non-contact charger 144 can be configured in various forms. FIGS. 5A and 5D are front views schematically illustrating a configuration example of the power supply unit 143 in the charging pole 14 according to the first embodiment.

  For example, as shown in FIG. 5A, the other end of the power supply cord 145 that electrically connects one end to the non-contact charger 144 housed in the charger 141 is connected to the power supply 146. The body 146 includes a charged storage battery 146a such as a dry battery, and an electric circuit 146b that transmits the power of the storage battery 146a to function as a non-contact charger 144 (for example, the non-contact charger 144 is formed of a wireless charging coil based on the Qi standard. When it is present, a switching circuit, a transformer circuit, etc.). Therefore, wireless charging can be performed by holding the charger 141 using the charging pole 14 of the first embodiment over the rechargeable storage battery 11 via the charging mechanism unit 12.

  In addition, as shown in FIG. 5B, for example, the other end of the power supply cord 145 that electrically connects one end to the non-contact charger 144 housed in the charger 141 is connected to the power supply 146. The power supply 146 is configured to be electrically connectable to the AC adapter 30 via the charging cord 20, and the electric circuit 146 b (for example, non-contact charging) for transmitting the power of the AC adapter 30 to make the non-contact charging member 144 function. When the body 144 is formed of a wireless charging coil based on the Qi standard, it can be formed of a switching circuit, a transformer circuit, or the like.

  In the example illustrated in FIG. 5B, a connection housing 146 c that can be electrically connected to the connection connector 20 a at one end of the charging cord 20 is provided in the electric circuit 146 b that forms the power supply body 146. The connection connector 20b at the other end of the charging cord 20 can be connected to the output terminal 30a of the AC adapter 30. Therefore, an input terminal (not shown) of the AC adapter 30 is connected to an outlet of an AC power supply, and the AC adapter 30 and the electric circuit 146 b constituting the power supply 146 are electrically connected to each other through the power supply cord 145 and the charging cord 20. In the connected state, wireless charging can be performed by holding the charger 141 using the charging pole 14 according to the first embodiment over the rechargeable storage battery 11 via the charging mechanism unit 12.

  That is, the power supply 146 in the charging pole 14 of the first embodiment can be configured with various structures as long as power is supplied so that the non-contact charger 144 functions.

  In the example of the present embodiment, the charger 141 is held over the rechargeable storage battery 11 via the power storage portion 11a of the rechargeable storage battery 11 via the power storage surface 12b of the charging mechanism unit 12 exposed from the head box 1. Although the example in which the wireless charging is performed has been described, the power storage portion 11a of the rechargeable storage battery 11 may be directly exposed from the head box 1.

  Further, in the example of the present embodiment, the example in which the charging mechanism unit 12 supporting the rechargeable storage battery 11 is disposed on the right end side in the longitudinal direction of the head box 1 has been described, but the disposition position and the number are arbitrary. In addition, as illustrated in FIG. 6A, for example, a charging mechanism 12 that supports the rechargeable storage battery 11 may be provided at a plurality of positions of the head box 1.

  In the example of the present embodiment, the power storage surface 12b of the charging mechanism unit 12 (or the power storage unit 11a of the rechargeable storage battery 11) is exposed from the front side of the headbox 1, and the wireless charging is performed by holding the charger 141 from the front. Although an example of performing charging has been described, it is not necessary to limit to this. For example, when providing the power storage portion 11a of the rechargeable storage battery 11 on the outer peripheral surface of the head box 1, for example, as illustrated in FIG. 6B, from the lower surface side of the head box 1, or as illustrated in FIG. 6C. Alternatively, wireless charging may be performed from the side of the head box 1.

(Feeding pole of Embodiment 2)
FIGS. 7A to 7D are a perspective view, a front view, a cross-sectional side view, and a rear view, respectively, illustrating a schematic configuration of the charging pole 14 according to the first embodiment. In FIG. 7, the same components as those in the first embodiment are denoted by the same reference numerals.

  In the above-described charging pole 14 of the first embodiment, an example in which the power supply unit 143 is provided has been described. In the second embodiment, an AC cable 147 for power supply is used instead of providing the power supply unit 143.

  As in the first embodiment, the charger 141 is formed of a rectangular parallelepiped synthetic resin material containing a non-contact charger 144 (for example, a wireless charging coil based on the Qi standard). The non-contact charger 144 is capable of contactless power supply to the rechargeable battery 11 when the non-contact charger 144 is disposed to face the power storage portion 11a (see FIG. 4) of the rechargeable battery 11 via the power storage surface 12b of the charging mechanism unit 12. It is a functional part that performs.

  As in the first embodiment, the rod-shaped body 142 has an upper end attached to substantially the center of the front side of the charger 141, and in this example, a hollow bent from the upper end and extending downward with a length that can be gripped by the operator. It is formed of a columnar synthetic resin material.

  However, the lower end of the rod 142 is open, an AC cable 147 for electrically connecting one end to the non-contact charger 144 passes through the hollow part of the rod 142, and the other end of the rod 142 is open. The power supply adapter 147a extends from the lower end and is exposed and can be connected to an AC power outlet. Note that the AC cable 147 may be configured to be held along the rod-shaped body 142 instead of being inserted through the hollow portion thereof.

  For this reason, when the power adapter 147a is connected to the outlet of the AC power supply, the wireless charging is performed by holding the charger 141 using the charging pole 14 of the second embodiment over the rechargeable storage battery 11 via the charging mechanism unit 12. Thus, the charging pole 14 of the second embodiment has the same operation and effect as the first embodiment. The various modifications described with reference to FIG. 6 can be applied to the case where the charging pole 14 according to the second embodiment is used.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. For example, in the description of the above-described embodiment, the wireless charging is not limited to a case where the wireless charging is physically performed in a non-contact state, but includes a physical contact state from the viewpoint of realizing the wireless charging. Further, in the charging poles 14 of the first and second embodiments, the rod-shaped body 142 may be expandable and contractible. Further, the rechargeable storage battery 11 may be fixedly held directly on the head box 1 without the intermediation of the charging mechanism unit 12 so that the rechargeable storage battery 11 can be charged by direct surface contact or non-contact. Good.
