As the movable panel 1 moves, its outer peripheral surface comes into contact with one of the inner surfaces of both side walls 5c and 5c of the upper rail 5 and is vertical. The shaft 31 rotates about the axis.
Although the configuration and structure of the lower rail 6 are not particularly limited, the lower rail 6 is open from the position where the lower rail 6 blocks the half area of the opening 8a with the movable panel 1 (see FIG. 1A). Up to the position where the entire portion 8b is blocked (see FIG. 1B), it is laid on the floor 9 and has a vertical cross-section substantially U-shaped or substantially C-shaped opening upward. Although not shown in the figure, the lower guide portion may be, for example, a door wheel or the like in which the traveling direction is freely set.

The configuration and structure of the upper rail 5 are not particularly limited. In the illustrated example, the upper rail 5 is provided from the left end of the wall 8 to the area where the half area of the large opening 8 a is blocked by the movable panel 1.
The upper rail 5 is formed of a metal material, a hard synthetic resin material, or the like, and has a linear shape and a substantially U-shaped or substantially C-shaped vertical section.
In the present embodiment, the upper rail 5 is fixed in a state of opening downward along the ceiling 7 as shown in FIG. The upper rail 5 may be fixed to the ceiling 7 from the lower side with a fixing stopper such as a screw.
As shown in FIG. 2 (a), the upper rail 5 includes an upper plate portion 5b, both side wall portions 5c and 5c coupled so as to hang down from both side edges of the upper plate portion 5b, and both side wall portions. Locking pieces 5d and 5d that protrude toward the inner side in the width direction of the upper rail 5 are provided at the lower edge portions of 5c and 5c. Further, an opening 5 a is formed between the locking pieces 5 d and 5 d, and the opening 5 a is formed over the entire length of the upper rail 5.
The vertical cross-sectional shape of the upper rail 5 is substantially C-shaped, and the power cord 2 connected to the power feeding unit 20 is accommodated in the upper rail 5 so as to follow the movement of the movable panel 1. The rail 5 is provided with a rail cover portion 50 that closes the opening 5a.
Thus, since the rail cover part 50 which closes the opening part 5a of the upper rail 5 is provided, even if the power cord 2 connected to the electric power feeding part 20 of the movable panel 1 is accommodated in the upper rail 5, The drooping can be prevented and the extra length wiring process can be performed with good appearance.

The configuration and structure of the rail cover part 50 are not particularly limited as long as the opening part 5a is blocked and the power cord 2 and the movable panel 1 accommodated in the upper rail 5 are not obstructed.
For example, as in this embodiment, there is a fixed rail cover 51 that closes the opening 5a, and a movable rail cover 52 that is arranged above the fixed rail cover 51 and that is connected to the movable panel 1 and moves as the movable panel travels. It is good also as what you are doing.

FIG. 2B is a schematic perspective view seen from the upper side of the ceiling 7 in order to show the appearance of the upper rail 5 in an easy-to-understand manner. As shown in FIG. Neither the part 50 nor the power cord 2 can be seen.
FIG. 2C is a schematic perspective view in which the illustration of the upper plate portion 5b and the side wall portion 5c on the front side (the side opposite to the wall 8) is omitted for easy understanding of the internal structure of the upper rail 5. FIG.
As shown in FIGS. 2 (a) and 2 (c), the fixed rail cover 51 of the illustrated example is formed of a vertically long thin plate body, and both end portions in the width direction are locked by the locking pieces 5d and 5d, and the opening portion. It is provided so as to block 5a.
The fixed rail cover 51 is not provided so as to block all the openings 5a formed over the entire length of the upper rail 5, but covers the opening 5a from the left end of the wall 8 to the left end of the small opening 8b. (See FIGS. 1A and 1B).
The fixed rail cover 51 only needs to be locked to the locking pieces 5d and 5d at both ends in the width direction, and may be fixed to the locking pieces 5d with an adhesive, a fixture, or the like. Further, when the movable rail cover 52 that moves as the movable panel 1 moves does not come into contact, the fixed rail cover 51 may not be fixed to the locking pieces 5d and 5d.

On the fixed rail cover 51, a movable rail cover 52 (refer to the direction of the arrow d1 in FIG. 2C), which is also formed of a vertically thin plate body and moves with the movement of the movable panel 1, is provided.
The length of the movable rail cover 52 is set according to the movable range of the movable panel 1, and the opening 5 a moves from one opening 8 b not covered by the fixed rail cover 51 to the other opening 8 a. The power cord 2 is provided so as not to hang down as the panel 1 moves.
The movable rail cover 52 has a length that is accommodated in the upper rail 5 when the movable panel 1 is installed at a position where the movable panel 1 closes the opening 8b.
In FIGS. 1A and 1B, the movable rail cover 52 is indicated by a one-dot chain line in order to distinguish it from the fixed rail cover 51 and the power cord 2 indicated by a dotted line.
The movable rail cover 52 may be supported on one side by a fixture 4 which will be described later in a state of being floated on the fixed rail cover 51, or rail grooves on the inner surfaces of both side walls 5 c, 5 c of the upper rail 5, Alternatively, a rail convex portion may be formed and movable in the left-right direction. The movable rail cover 52 may be configured to slide on the fixed rail cover 51. That is, as shown in FIGS. 2A and 2C, a gap may be provided between the fixed rail cover 51 and the movable rail cover 52, or the movable rail cover 51 is movable on the fixed rail cover 51. The rail cover 52 may be provided in an overlapping manner.

As shown in FIG. 3B, one end of the movable rail cover 52 is provided in the vicinity of the corner of the upper end surface of the movable panel 1, specifically, closer to the corner of the one upper guide 3. The fixed panel 4 is connected to the movable panel 1. Therefore, an insertion hole (not shown) for connecting to the fixture 4 is formed at one end of the movable rail cover 52 (the right end in the illustrated example).
That is, since the upper guide portion 3 provided on the left side of the movable panel 1 and the right end of the movable rail cover 52 are connected by the fixture 4, an insertion hole is formed at the right end of the movable rail cover 52.
The connection structure between the movable panel 1 and the movable rail cover 52 is not particularly limited as long as the movable rail cover 52 moves with the movement of the movable panel 1, and the connection structure using the fixture 4 is not particularly limited. The illustrated fixture 4 includes a bolt 40 and a cylindrical portion 41 that is hollow and has an internal thread formed on the inner wall, and is set so that the insertion hole of the movable rail cover 52 is positioned on the cylindrical portion 41. If the bolt 40 is inserted and screwed in the state, the movable rail cover 52 can be connected to the movable panel 1.
Above the movable rail cover 52, a power cord 2 for sending electricity supplied from the distribution board to the power feeding unit 20 is wound.

The power cord 2 may be bent or pulled out with the movement of the movable panel 1 in the upper rail 5, but a cord reel portion 22 may be provided as shown in the figure.
That is, a cord reel portion 22 that can freely wind and unwind the power cord 2 may be provided at the end of the upper rail 5 in the longitudinal direction.
FIG. 4A shows an example in which a cord reel portion 22 is provided at the left end corner of the wall 8 above.
The configuration and structure of the cord reel unit 22 are not particularly limited, and the cord reel unit 22 that does not damage or break the power cord 2 and does not hinder the movement of the movable panel 1 is adopted. It is only necessary to wind up the long part or feed out the necessary length. For example, a rotating body around which the power cord 2 is wound or a mainspring spring can be provided.
According to this, it is possible to prevent the extra length portion of the power cord 2 from being tangled in the upper rail 5.

The power cord 2 accommodated in the upper rail 5 is drawn into the power feeding unit 20 of the movable panel 1. At this time, the power cord 2 is not drawn outside the movable panel 1 but is drawn into the movable panel 1. May be.
That is, as shown in FIG. 4 (b), the power cord 2 is inserted into the space S formed between the pair of plate members 10 and 10 and the frame member 11 from the upper rail 5 at the upper end of the movable panel 1. It is good also as what has the drawing-in part 2a drawn in to the electric power feeding part 20 side.
In the illustrated example, the core material 11a disposed horizontally above the movable panel 1 is divided at a substantially central portion of the movable panel 1, and a drawing space S1 is formed between the core material 11a and the core material 11a.
And the example which provided the drawing-in part 2a in one upper corner | angular part (core material 11a distribute | arranged to the left side in the example of a figure) of the core material 11a is shown. According to this, the power cord 2 arranged in the upper rail 5 can be drawn into the space S and the power feeding unit 20 through the drawing space S1.

The configuration and structure of the lead-in part 2a are not particularly limited as long as the power cord 2 can be smoothly drawn into the power feeding part 20.
The drawing-in part 2a shown in the figure is an example including a roller part 20b for guiding the power cord 2 to the power feeding part 20 side and support parts 20a and 20a for supporting both ends of the roller part 20b. The roller portion 20b is configured to rotate around a shaft portion (not shown) supported by the support portions 20a and 20a.
Since the roller portion 20b is provided at the upper corner portion of the core member 11a of the movable panel 1, the power cord 2 accommodated in the upper rail 5 provided substantially horizontally is arranged in a direction substantially perpendicular to the upper rail 5. To the power feeding unit 20 side.
When the power cord 2 is pulled toward the power feeding unit 20, the roller unit 20 b moves in the direction of the power feeding unit 20 (see the direction of arrow d <b> 2 in FIG. 4B) as the power cord 2 is drawn out from the cord reel unit 22. Rotate. On the other hand, when the power cord 2 is taken up by the cord reel portion 22, the roller portion 20b moves in a direction opposite to the direction of the power feeding portion 20 as the power cord 2 is pulled into the upper rail 5 (FIG. 4B). ) (See arrow d3 direction).
If the lead-in part 2a is provided in this way, the power cord 2 accommodated in the upper rail 5 can be drawn into the moving panel 1 without connecting the outside of the moving panel 1, and has a good appearance. Can be.

As shown in FIG. 4B, the roller portion 20b is desirably provided so as to protrude from the concave portion 11aa provided in the upper corner portion of the core material 11a. Further, if the protruding amount at this time is a position where it does not come into contact with the upper guide portion 3, the power cord 2 can be smoothly wound and fed out by the cord reel portion 22, and the traveling of the movable panel 1 is also smooth. It can be.
Although not shown here, a gap is formed between the power cord 2 and the rail cover portion 50, so that the power cord 2 is lowered in the upper rail 5 according to the total length of the upper rail 5. You may make it provide the support part supported from. Also in this case, since the power cord 2 does not bend in the upper rail 5, the power cord 2 can be smoothly wound and fed out by the cord reel portion 22, and the moving panel 1 can be smoothly run. It can be.

Next, the relationship between the travel of the movable panel 1 and the rail cover unit 50 will be described with reference to FIGS. 1 (a) and 1 (b).
First, the state of FIG. 1A shows a state in which the movable panel 1 is located at the rightmost end of the upper rail 5 and the lower rail 6. In this case, the movable rail cover 52 is most pulled out from the fixed rail cover 51. At this time, the power cord 2 is also most pulled out from the cord reel portion 22, but the power cord 2 is hidden by the fixed rail cover 51 and the movable rail cover 52.
The state of FIG. 1B shows a state in which the movable panel 1 is located at the leftmost end of the lower rail 6. In this case, the movable rail cover 52 is in a state where both are accommodated in the upper rail 5 so as to overlap above the fixed rail cover 51. At this time, the power cord 2 is wound most around the cord reel portion 22, and the power cord 2 can be prevented from being tangled in the upper rail 5.
Thus, the movable panel 1 is allowed to travel from the position shown in FIG. 1A to the position shown in FIG. If the movable panel 1 moves to the left end side of the wall 8, the power cord 2 is wound up by the cord reel portion 22, while if the movable panel 1 moves to the right end side of the wall 8, the power cord 2 moves to the cord reel portion 22. It is paid out by.

As described above, according to the movable panel 1 of the present embodiment, for example, when the user wants to move the television set as the load 21 to an easily viewable position, the movable panel 1 may be moved along the upper rail 5. At this time, the power cord 2 connected to the power supply unit 20 and accommodated in the upper rail 5 does not hang down from the upper rail 5, so that it does not look good and does not disturb the traveling of the movable panel 1.
In addition, when the underload structure is used as described above, the movable panel 1 can be moved to a desired position in a stable state even when a heavy load 21 is installed on the movable panel 1 as in a television.

Next, a modified example of the structure for supplying power to the moving panel according to the present embodiment will be described with reference to FIG.
In the following modifications, differences from the above-described example will be mainly described, and the same components are denoted by the same reference numerals, and description thereof will be omitted or simplified.
In this modification, the rail cover 50 is different from the above-described one, and the rail cover 50 is integrally formed with the power cord 2.
As shown in FIG. 5A, the power cord 2 has a substantially rectangular shape that is flat in the lateral direction, and the width direction dimension of the lower surface 2b of the power cord 2 is larger than the width direction dimension of the opening 5a. By this, it is comprised so that the opening part 5a can be covered (refer FIG.5 (b)). That is, the lower surface 2 b of the power cord 2 also serves as a rail cover portion 50 that closes the opening 5 a of the upper rail 5.

The shape of the power cord 2 is not limited to the illustrated example, and may be any shape that can be wound and unwound by the cord reel unit 22. For example, the cross section may be an elliptical shape or a trapezoidal shape.
In this case, since the upper rail 5 does not have the fixed rail cover 51 and the movable rail cover 52 shown in FIG. 1 and the like, the movable range of the movable panel 1 can be increased. That is, for example, if the lower rail 6 provided in FIG. 1A has substantially the same length as the upper rail 5, the end of the rails 5, 6 from end to end (from the right end to the left end) It can be a movable range.

  The shapes and configurations of the movable panel 1, the power cord 2, the upper guide portion 3, the upper rail 5, the power feeding portion 20, the rail cover portion 50, the pull-in portion 2 a and the like described in the above embodiment are not limited to the above examples. Further, the shape, configuration, installation position, and the like of the cord reel portion 22 are not limited to the illustrated example, and may be provided at the right end of the wall 8. The installation position of the power feeding unit 20 is not limited to the illustrated example. The configuration of the openings 8a and 8b provided on the wall 8 is not limited to the illustrated example. For example, the movable panel 1 may be provided so as to be able to run in front of the storage cabinet, and the movable panel 1 is used as a sliding door. May be used. Furthermore, although the case where the lower rail 6 was provided was demonstrated here, this is not limited to the example of illustration, It is good also as the upper suspension structure which drive | works the movable panel 1 along only the upper rail 5, or the downward direction of the movable panel 1 A caster that travels on the floor 9 may be provided.
