DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a lighting fixture and a system bed according to an embodiment of the present invention will be illustrated in detail with reference to the drawings.

As shown in FIG. 1, a lighting fixture 1 according to this embodiment is fixed to the top surface of a desk 2. Further, in this embodiment, a system bed 6 is configured by the lighting fixture 1, the desk 2, the bed 3 having a lower space S in which the desk 2 can be stored, the chest of drawers 4, and the storage shelves 5. The system bed 6 can be used in various layouts in which the desk 2, chest of drawers 4, and storage shelves 5 are arranged differently. The bed 3 includes a bed 3a and a support portion 3b that supports the bed 3a against the floor surface so as to form a lower space S below the bed 3a. Although the support portion 3b is composed of a pair of side walls 3c, the present invention is not limited thereto. Further, although the system bed 6 has a chest of drawers 4 and a storage shelf 5, the present invention is not limited thereto. For example, the system bed 6 may have other furniture instead of the chest of drawers 4 and the storage shelves 5, or may not have the chest of drawers 4 and the storage shelves 5. Note that the lighting fixture 1 may be used by being fixed to the top surface of a desk other than the system bed 6.

As shown in FIGS. 2 and 3, the lighting fixture 1 includes a fixing part 7 having a lower surface 7a fixed to the top surface of the top plate 2a of the desk 2, and an arm 9 connected to the fixing part 7 and having a lamp 8. have. Note that the fixing part 7 is not limited to being fixed to the top surface of the top plate 2a of the desk 2. For example, the fixing part 7 may have a structure in which a shelf board is provided on the desk 2 and the bottom surface 7a of the fixing part 7 is fixed to the top surface of the shelf board. Good too.

The fixing part 7 is configured as a clamp device having a clamping plate 7b facing the lower surface 7a and an operating part 7c for moving the clamping plate 7b toward the lower surface 7a. Although the operating section 7c is composed of a knob for rotational operation, the present invention is not limited thereto. By operating the operating portion 7c, the top plate 2a can be sandwiched between the lower surface 7a and the upper surface of the tightening plate 7b, thereby fixing the fixing portion 7 to the top plate 2a. Note that the fixing portion 7 is not limited to being configured as a clamp device, and may be configured to be fixed to the desk 2 with fasteners such as bolts and nuts.

The fixing part 7 has a fixing part main body 7d having a lower surface 7a. The fixing part main body 7d has an insertion opening 7e that opens on the upper surface of the fixing part main body 7d. The base end 9a of the arm 9 is removably inserted into the insertion opening 7e, thereby connecting the arm 9 to the fixed part 7. That is, the base end 9a of the arm 9 is removably connected to the fixing part 7. Therefore, since the fixing part 7 can be attached to the top plate 2a with the arm 9 removed from the insertion opening 7e, the fixing part 7 can be easily attached to the top plate 2a. However, the base end 9a of the arm 9 may be integrated with the fixing part 7.

Further, the base end portion 9a of the arm 9 is rotatable about a central axis O perpendicular to the lower surface 7a while inserted into the insertion port 7e. Therefore, by rotating the base end 9a of the arm 9 while inserted into the insertion port 7e, the direction of the entire arm 9 can be adjusted, so that an excellent movable range of the arm 9 can be realized. Note that the central axis O does not have to be perpendicular to the lower surface 7a. Further, the base end portion 9a of the arm 9 may be configured to be unrotatable when inserted into the insertion port 7e.

In this way, by configuring the base end 9a of the arm 9 to be removably and rotatably inserted into the insertion opening 7e provided in the fixed part 7, the height H1 ( (see FIG. 4), it is possible to achieve both the above-mentioned excellent installation workability of the fixing part 7 and the excellent movable range of the arm 9.

The arm 9 includes a first link 10a forming a base end 9a, a second link 10b connected to the first link 10a via a rotatable first joint 11a, and a second link 10b rotatable to the second link 10b. A third link 10c that is connected to the second joint 11b, a fourth link 10d that is rotatable to the third link 10c, and a fourth link that is rotatable to the fourth link 10d. It has a fifth link 10e connected via a joint 11d and provided with a lamp 8. Thus, the arm 9 has five links 10 and four joints 11. However, as long as the arm 9 has at least one rotatable joint 11, the number of links 10 and joints 11 can be increased or decreased as appropriate.

The first joint 11a is rotatable about a central axis X1 parallel to the lower surface 7a. The second joint 11b is rotatable about a central axis X2 parallel to the lower surface 7a. The third joint 11c is rotatable about a central axis X3 parallel to the lower surface 7a. The fourth joint 11d is rotatable about a central axis X4 located in a plane perpendicular to the central axis X3. Note that the directions of the central axes X1 to X4 can be changed as appropriate. Furthermore, each joint 11 is not limited to a configuration that can be rotated around only one axis, but may be configured so that it can be rotated around only two axes, or can be configured so that it can be rotated around three axes. It may also be configured as a joint.

The lamp 8 has a light source such as a light emitting diode (LED), and can illuminate the top surface of the top plate 2a of the desk 2 by supplying electricity to the light source via the power cord 12. The power cord 12 is drawn into the arm 9 at a position closer to the lamp 8 than the first joint 11a. That is, the passage portion 13 (see FIG. 4) through which the power cord 12 passes from the outside of the arm 9 toward the inside of the arm 9 is provided at a position closer to the lamp 8 than the first joint 11a. Therefore, since it is not necessary to arrange the power cord 12 inside the first joint 11a, the first joint 11a is downsized and the height H1 of the first joint 11a closest to the fixed part 7 among the four joints 11 (Fig. 4 ) can be lowered. Note that the height H1 of the first joint 11a means the height from the lower surface 7a of the fixing portion 7. Further, by configuring the power cord 12 to be drawn into the arm 9, the aesthetic appearance of not only the lighting fixture 1 but also the desk 2 and the system bed 6 as a whole can be improved. Note that the power cord 12 is not limited to a configuration in which it is drawn into the arm 9 at a position closer to the lamp 8 than the first joint 11a. For example, it may be configured to be drawn into the arm 9 around the third joint 11c. Further, the lighting fixture 1 is not limited to the configuration having the power cord 12 extending outward from the arm 9, but may have a configuration having an internal power source such as a dry battery, for example.

The second link 10b has an operation panel 14 for turning on/off the lamp 8. The operation panel 14 has, for example, an ON/OFF button and an illuminance adjustment button. Although the operation panel 14 is provided on the front side of the second link 10b, the operation panel 14 is not limited thereto, and may be provided on the side surface of the second link 10b, for example. As shown in FIG. 4, the power cord 12 is drawn into the arm 9 at the lower part of the back of the second link 10b. Therefore, the power cord 12 does not get in the way when using the lamp 8, and the aesthetic appearance can be further improved. Note that the power cord 12 may be configured to be drawn into the arm 9 at other parts of the second link 10b.

The arm 9 has a hollow structure, and circuits and wiring for the lamp 8, including circuits and wiring for the operation panel 14, are arranged within the arm 9 and connected to the power cord 12.

As shown in FIGS. 2 and 4, the arm 9 is configured to be foldable up to the height H1 of the first joint 11a closest to the fixed part 7 among the four joints 11. That is, the arm 9 can be folded until the height H2 of the arm 9 becomes the height H1 of the first joint 11a, as shown in FIG. In other words, the arm 9 is foldable until the first joint 11a is at the top T of the arm 9, as shown in FIG. Note that the height H2 of the arm 9 means the height from the lower surface 7a of the fixing portion 7. Further, the uppermost portion T of the arm 9 is the portion having the highest height from the lower surface 7a of the fixing portion 7. The top T of the arm 9 changes depending on the rotation status of each joint 11, that is, the attitude of the arm 9. For example, in the posture shown in FIG. 2, the top T of the arm 9 is the second joint 11b. By rotating the second joint 11b from this position, the third joint 11c may become the uppermost position T, for example.

As shown in FIG. 2, the height H1 of the first joint 11a is equal to or less than the height H3 of the lower space S from the upper surface of the desk 2 to which the lower surface 7a of the fixed part 7 is fixed (that is, the upper surface of the top plate 2a). It becomes. That is, H1≦H3. Therefore, by folding the arm 9 to the height H1 of the first joint 11a, that is, until H2=H1, the desk 2 can be moved to the bed 3 as shown in FIG. 5 while the lighting fixture 1 remains fixed. It can be stored in the lower space S.

Further, the arm 9 is foldable so that the arm 9 fits inside the top plate 2a of the desk 2 and the height H2 of the arm 9 becomes the height H1 of the first joint 11a when viewed from above. More specifically, by rotating the second joint 11b and folding back the third link 10c toward the second link 10b, the arm 9 can be housed inside the top plate 2a. By folding the arm 9 in this manner, the desk 2 can be stored in the lower space S even if the lower space S becomes narrow due to the placement of furniture such as the storage shelf 5.

It goes without saying that the embodiment described above is only one example of the embodiment of the present invention, and that various changes can be made without departing from the gist of the invention.
