  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. For the sake of convenience, the same reference numerals are given to the portions having the same operational effects, and the description thereof is omitted. Note that the present invention can be widely applied to a charging device for portable electronic devices, but here, an example in which the present invention is applied to a so-called charging device for a child device in a telephone device will be described.

  In FIG. 1, the subunit | mobile_unit 10 in the telephone apparatus and the main-body part 50 of the charging device 1 for charging this subunit | mobile_unit 10 are shown. The subunit | mobile_unit 10 is exhibiting the substantially rectangular parallelepiped shape, and is equipped with the transmitter 11 on the one side of the longitudinal direction in the front side, and the receiver 13 on the other side (refer FIG. 2). In addition, about a communication part etc. with a main | base station (illustration omitted), since it is a prior art, description is abbreviate | omitted. Concave portions 15a and 15b are formed at the end portion on the transmitter 11 side in the longitudinal direction of the handset 10 and at the front edge portion, and charging terminals 17a and 17b are formed in the concave portions 15a and 15b. Is provided. Further, at the end of the handset 13 in the longitudinal direction of the handset 10 and at the front edge, recesses 18a and 18b having substantially the same shape as the recesses 15a and 15b are formed (FIG. 2). Thereby, as for the edge part of the longitudinal direction in the front side of the subunit | mobile_unit 10, one side and the other side become a shape substantially the same. In addition, a light emitting means 19 such as an LED is provided on the back surface of the slave unit 10 so that it is lit and informed in a predetermined state, for example, in a charged state. In the illustrated example, the light emitting means 19 is provided closer to the handset 13 side, so that the top and bottom of the handset 10 can be confirmed by visual observation from the back side.

  The main body portion 50 of the charging device 1 includes a bottom surface portion 51 that becomes a bottom surface when placed horizontally, wall portions 53 and 54 that project from both ends in the longitudinal direction of the bottom surface portion 51, and the bottom surface portion 51. The wall portions 55 and 56 projecting from both ends in the short-side direction have a substantially concave shape, and the child device 10 is accommodated in the concave opening 52. In the illustrated example, a notch 55a is provided on one of the wall portions 55 and 56 (the wall portion 55 in the illustrated example) formed at the end of the bottom surface portion 51 in the short-side direction. The machine 10 can be easily taken in and out of the opening 52. Convex portions 53a, 53b, 54a, 54b corresponding to the concave portions 15a, 15b (18a, 18b) provided in the slave unit 10 are formed on the bottom surface portion 51 side of the wall portions 53, 54, and these convex portions 53a are formed. , 53b, 54a, 54b are provided with charging terminals 57a, 57b, 58a, 58b, respectively. Note that the size of the inside of the opening 52 is such that a predetermined play (clearance) occurs when the child device 10 is accommodated.

  As described above, the charging terminals 57a, 57b, 58a, and 58b are provided at both ends in the longitudinal direction of the main body 50, so that the insertion direction of the child device 10 is changed to the left and right as shown in FIGS. In any case, the charging terminals 17a, 17b of the slave unit 10 are in contact with any one of the charging terminals 57a, 57b, 58a, 58b of the main body 50. In FIG. 2 (a), the handset 13 side is on the right and the handset 11 side on which the charging terminals 17a and 17b are provided is on the left, while in FIG. 2 (b), the handset 13 side is on the contrary. On the left, the transmitter 11 side where the charging terminals 17a and 17b are provided is on the right. Further, as shown in the figure, the charging terminals 57 a, 57 b, 58 a, 58 b of the main body 50 are formed by urging means such as a torsion coil spring made of a metal wire, for example, and the slave unit 10 is accommodated in the opening 52. When it is done, it contacts the charging terminals 17a, 17b of the slave unit 10 with certainty. Thus, the main-body part 50 of the charging device 1 becomes a structure which does not choose the insertion direction of the subunit | mobile_unit 10 when using the main-body part 50 as horizontal installation alone.

  FIG. 3 shows the main body 50 and the wall adapter 100 constituting the charging device 1. As described above, the main body 50 is supposed to be placed horizontally when used alone, but can be used in a substantially vertical state by being attached to the wall adapter 100. The wall-hanging adapter 100 is hooked on a screw or the like fixed to a wall surface or the like, and as shown in FIG. 3A, hooking portions 71a and 71b for hooking on the screw or the like are vertically moved. The wall-hanging portion 70 is provided, and a panel portion 80 having an L-shape in a side view that is pivotally supported by the lower end portion of the wall-hanging portion 70. Engagement pieces 73 a, 73 b, 73 c, 73 d projecting outward in the short direction are provided at substantially the center of the wall hanging part 70, and the engagement pieces 73 a, 73 b, 73 c, 73 d and the bottom part 51 of the main body part 50. The main body 50 is locked to the wall-mounted adapter 100 by a locking piece (not shown) that protrudes inward in the short direction provided on the back surface of the wall adapter. In addition, as shown with the white arrow in a figure, the main-body part 50 is latched by making it slide after making the main-body part 50 contact | abut on the wall hanging adapter 100. FIG.

  FIG. 3B shows a state where the main body 50 is locked to the wall adapter 100. In the illustrated example, the wall portion 55 in which the notch 55a is formed in the main body portion 50 is the left side of the drawing, but the wall portion can be obtained by locking the main body portion 50 to the wall adapter 100 in a state where the main body portion 50 is turned upside down. 55 can also be the right side. The panel unit 80 is formed of, for example, a transparent synthetic resin, and the light emitting unit 19 passes through the panel unit 80 even when the handset 10 is accommodated with the handset 13 provided with the light emitting unit 19 facing down. Is visible.

  The manner in which the panel unit 80 of the wall adapter 100 rotates while the main body unit 50 is locked will be described with reference to FIGS. 4 to 8 are sectional views showing a state in which the charging device 1 is hung on the wall. In the drawing, the left side is the wall side and the right side is the outside. A rotation shaft 81 provided on one end side of the panel portion 80 is pivotally supported on a rotation center C provided on a support piece 72 protruding outward at a lower portion of the wall hanging portion 70. The panel portion 80 includes a horizontal plate portion 85 extending from the position of the rotation shaft 81 to a position further outside the opening surface of the main body portion 50, and a lower portion of the opening portion 52 bent upward from there. It is comprised by the vertical board part 87 extended to the position of about 1/3. Further on the wall side of the rotating shaft 81 of the panel portion 80, an abutting piece 83 with which a lower end portion 76 of a cam follower 75 slidably provided at a lower portion of the wall hanging portion 70 is abutted with the horizontal plate portion 85. Is formed. The cam follower 75 is urged downward by an urging member 77 such as a coil spring disposed on the upper portion thereof, whereby the cam follower 75 presses the contact piece 83 downward in the state shown in FIG. It will be. In this way, the abutting piece 83 formed on the wall side (left side in the drawing) from the rotation shaft 81 is pressed downward, whereby the horizontal plate portion formed on the outer side (right side in the drawing) from the rotation shaft 81. A rotational force acting upward is applied to 85 and the vertical plate portion 87. As shown in FIG. 8A, this rotational force is generated when the slave unit 10 is accommodated in the opening 52 of the main body 50, and the slave unit 10 is placed inside the opening 52 (on the left side in the drawing). ) So that the child device 10 can be supported in the opening 52 and the charging terminals 17a and 17b of the child device 10 and the charging terminals 57a and 57b of the main body portion 50 are reliably in contact with each other. be able to. As described above, the panel unit 80 functions as a pressing unit that presses the inside of the opening while covering a part of the slave unit 10. In the illustrated example, when the child device 10 is accommodated in the opening 52, the vertical plate portion 87 is substantially vertical, and the side surface of the vertical plate portion 87 on the opening 52 side and the back surface of the child device 10 come into contact with each other. It is like that. At this time, the lower end of the child device 10 is placed on the wall portion 54 of the main body 50. In addition, although the receiver 13 is shown in the upper part and the transmitter 11 and the charging terminals 17a, 17b are shown in the lower state, the opening 52 is shown as an example. In this case, the charging terminals 17a and 17b come into contact with the charging terminals 58a and 58b of the main body 50.

  As shown in FIG. 4B, the lower end 76 of the cam follower 75 is inclined upward from the wall side to the outside (from the left side to the right side in the drawing). As a result, the rotational force continues until the angle of the inclined surface and the angle of the contact piece 83 coincide with each other, so that the rotation of the panel unit 80 is performed while the horizontal plate 85 is horizontal. Will never stop. Note that the lower end portion 76 of the cam follower 75 in the state of FIG. 4 is in contact with the edge portion 83a of the contact piece 83 at the position of the point P1 in a side view.

  FIG. 5 shows a state in which the panel unit 80 is rotated against the rotational force from the state of FIG. When the user accommodates the handset 10 in the main body 50 or removes it from the main body 50, the panel 80 needs to be rotated in this way. When the user accommodates the child device 10 in the main body 50 or removes the child device 10 from the main body 50, as shown in FIG. When the inner surface of the panel portion 80 is pressed, the panel portion 80 freely rotates. Thus, since the panel part 80 rotates by the movement of the subunit | mobile_unit 10 by a user, it is not necessary to move the subunit | mobile_unit 10 to a fixed direction like a prior art example. Further, as shown in the illustrated example, since the pivot shaft 81 of the panel unit 80 is provided on the side of the wall side, when the panel unit 80 rotates, the lower end portion of the vertical plate portion 87 is on the lower side. Move to. Thereby, the vertical plate portion 87 moves so as to move downward while rotating, and the child device 10 can be sufficiently taken in and out without greatly rotating the panel portion 80. In addition, the lower end 76 of the cam follower 75 in the state of FIG. 5 is in contact with the edge 83a of the contact piece 83 at the position of the point P2 in a side view, and the position of this point P2 is the point P1 in FIG. Outside of the position (right side in the drawing).

  FIG. 6 shows a state in which the panel unit 80 is further rotated from the state of FIG. The lower end portion 76 of the cam follower 75 in the state of FIG. 6 is in contact with the edge portion 83a of the contact piece 83 at the position of the point P3 in a side view. The position of the point P3 is further outside (right side in the drawing) than the position of the point P2 in FIG. 5 and is an edge of the lower end 76 of the cam follower 75. When the panel portion 80 is further rotated, the edge portion 83a of the contact piece 83 of the panel portion 80 is disengaged from the edge portion of the lower end portion 76 of the cam follower 75 as shown in FIG. As a result, the contact piece 83 is not pressed (rotational force is not applied). Thus, when a large load is applied and the panel portion 80 is excessively opened, an overload prevention function is activated in order to prevent damage and the like.

  An arcuate portion 84 having an arcuate shape in a side view with a radius R from the rotation center C to the end of the abutting piece 83 is formed at the lower part of the abutting piece 83 and the horizontal plate portion 85 of the panel portion 80. Yes. Therefore, when the state shown in FIG. 6 is changed to the state shown in FIG. 7, that is, when the edge 83 a of the contact piece 83 of the panel 80 is disengaged from the edge of the lower end 76 of the cam follower 75. The position of 75 remains the same, and the lower end portion 76 of the cam follower 75 comes into contact with the arc portion 84. Thereby, when the overload prevention function is working (state of FIG. 7), the panel portion 80 can be rotated while the position of the cam follower 75 remains constant. Further, when returning from the state of FIG. 7 to the state of FIG. 6, since the position of the cam follower 75 in both states is the same, it is only necessary to rotate the panel portion 80 in the closing direction.

  Here, since the rotational force by the cam follower 75 described above acts as a resistance for the user when the handset 10 is attached and detached, it is preferable that the rotational force does not change greatly even if the rotation angle of the panel unit 80 changes. It is done. The rotational force T by the cam follower 75 is represented by the product of the force F generated by the bias of the cam follower 75 and the distance L from the position where this force is applied to the rotation center. Thereby, the rotational force T1 by the cam follower 75 in the state of FIG. 4 is expressed by T1 = F1 × L1. Similarly, the rotational force T2 by the cam follower 75 in the state of FIG. 5 is expressed by T2 = F2 × L2, and the rotational force T3 by the cam follower 75 in the state of FIG. 6 is expressed by T3 = F3 × L3. Here, since the bias of the cam follower 75 increases as the panel portion 80 rotates, the force F generated by the bias of the cam follower 75 satisfies F1 <F2 <F3, but the lower end of the cam follower 75 according to the rotation of the panel portion 80. Since the contact P (P1, P2, P3) between the contact point 76 and the contact piece 83 is shifted toward the rotation center C, the distance L from the position where the force F is applied to the rotation center C is L1> L2>. L3. Thereby, even if the rotation angle (theta) of the panel part 80 changes, it is thought that the rotational force T by the cam follower 75 does not change a lot. In the embodiment, the lower end portion 76 of the cam follower 75 is inclined upward from the wall side to the outside (from the left side to the right side in the drawing), so that the lower end portion 76 of the cam follower 75 is horizontal. Accordingly, when the contact point P between the lower end portion 76 of the cam follower 75 and the contact piece 83 is shifted toward the rotation center C as the panel portion 80 is rotated, the upward movement distance of the cam follower 75 is reduced. In the description of the rotational force T, the distance L from the position P where the force F is applied to the rotation center C is constant (in the embodiment, the radius is R), and the force F due to the bias of the cam follower 75 is described as Fcos θ. You can also

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention. For example, although the main body portion and the wall hanging adapter are configured as separate bodies and are integrated by engaging them, the present invention is not limited thereto, and the main body portion and the wall hanging adapter may be integrally formed. Absent.

  Although the example which the charging terminal in a subunit | mobile_unit was formed in the edge part of the front side was shown, it is not limited to this. For example, you may form a charging terminal in the surface of the edge part in the longitudinal direction of a subunit | mobile_unit (bottom surface when it stands upright). In this case, when the slave unit is accommodated in the charging device, the charged state can be obtained by not only turning the handset upside down but also turning it upside down.

  Although the example in which the rotational force (biasing force) in the rotation of the panel portion is performed by pressing the cam follower has been shown, the present invention is not limited to this. For example, a configuration in which an urging member such as a plate spring or a torsion coil spring is provided on the rotation shaft of the panel unit may be employed. However, in this case, the urging force of the urging member increases in proportion to the rotation of the panel portion.

  Although the rotation center provided in the support piece which protruded toward the outer side in the lower part of a wall hanging part was shown as a rotation center of a panel part, it is not limited to this. For example, a configuration in which the vertical plate portion is rotatably supported with respect to the horizontal plate portion and a cam follower that moves in the horizontal direction in the horizontal plate portion may be formed. In this case, the lower end portion of the vertical plate portion does not move downward as the panel portion rotates.

  Moreover, although the example in which the panel portion is formed of a transparent synthetic resin or the like has been shown, the present invention is not limited to this. The panel unit only needs to be able to confirm the light from the light emitting means of the slave unit at least in a state where the slave unit is accommodated.For example, only the portion corresponding to the light emitting unit is formed of a transparent synthetic resin or the like. A through hole may be formed.
