The lamp 9 includes a shade 10, a socket (not shown) provided in the shade 10, and a light source 11 such as a fluorescent lamp that is detachably attached to the socket. The support column 7 is configured to be substantially vertical in a state where the clamp 3 is fixed to the table top D of the desk, and the arm portion 8 is arranged around the axial direction of the substantially vertical support column 7. It is configured to rotate. A switch 6 for turning on and off the light source 11 of the lamp 9 is provided on the upper surface of the base 5. As described above, the lighting circuit for lighting the light source 11 of the lamp 9 is housed in the circuit housing 4 independent of the table lamp body 2 instead of the table lamp body 2. The desk lamp body 2 itself is slim.

  The clamp 3 includes a main metal member 12, a mounting body 13, and a screw body 14. The main metal fitting 12 is formed by bending a thick metal plate into a substantially U shape. In addition, the length of the upper horizontal piece 12A of this main metal fitting 12 is formed longer than the length of the lower horizontal piece 12B. Further, as described above, the base portion 5 of the table lamp body 2 is fixed to the upper horizontal piece 12A of the main metal fitting 12. Further, a screw hole 12C in which a female screw is formed is formed in the lower horizontal piece 12B of the main metal fitting 12. The screw body 14 is screwed into the screw hole. The screw body 14 includes a screw shaft 15 on which a male screw is formed, a knob 16 provided at the lower end of the screw shaft 15, and a fastening body 17 provided at the upper end of the screw shaft 15. ing. Then, by turning the knob 16, the screw shaft 15, and consequently the fastening body 17, can be moved up and down with respect to the lower horizontal piece 12B of the main metal fitting 12, and the upper horizontal piece 12A of the main metal fitting 12 and The top plate D of the desk can be clamped with the fastening body 17.

  Further, the attachment body 13 is formed by bending a metal plate into a substantially U shape. The lengths of the upper horizontal piece 13A and the lower horizontal piece 13B of the mounting body 13 are substantially equal, and the upper horizontal piece 13A and the lower horizontal piece 13B include a vertical piece of the mounting body 13 respectively. Through holes 13D and 13E are bored at positions equidistant from 13C and in the center in the width direction of the mounting body 13, respectively. These through holes 13D and 13E are not formed with female screws. The distance between the upper horizontal piece 13A and the lower horizontal piece 13B of the mounting body 13 is formed to be substantially equal to the length of the exposed portion of the screw shaft 15. As shown in FIGS. 2 and 3, the upper horizontal piece 13A of the mounting body 13 is located between the upper horizontal piece 12A and the lower horizontal piece 12B of the main metal fitting 12, and below the mounting body 13. The horizontal piece 13B is located below the lower horizontal piece 12B of the main metal fitting 12. The screw shaft 15 of the screw body 14 is passed through the through hole 13E, the screw hole 12C, and the through hole 13D in a state where the main metal fitting 12 and the mounting body 13 maintain the above-described positional relationship. In this state, the vertical piece 13C of the attachment body 13 is substantially parallel to the screw shaft 15 because the distance from the vertical piece 13C to the through holes 13D and 13E is substantially equal. Further, the upper horizontal piece 13A of the attachment body 13 is located immediately below the fastening body 17, and the lower horizontal piece 13B of the attachment body 13 is placed on the upper surface of the knob 16. That is, the attachment body 13 hardly moves in the vertical direction with respect to the screw body 14 and, as described above, no female screw is formed in each of the through holes 13D and 13E. It is pivotally supported so as to be rotatable with respect to the direction around the axis. Further, as shown in FIG. 4, when the attachment body 13 is rotated around the screw shaft 15, the attachment body 13 can be rotated at least 180 degrees from the vertical piece 12D of the main metal fitting 12. The attachment body 13 is formed sufficiently narrower than the distance to the screw hole 12C.

  The mounting body 13 is attached with the circuit housing 4 in which a lighting circuit (not shown) as an electric circuit or an electronic circuit is built. The circuit housing 4 is fixed to the vertical piece 13C of the mounting body 13 with screws or the like at the upper side surface. The circuit housing 4 is attached to the attachment body 13 so that the upper surface thereof is substantially the same height as the upper horizontal piece 12A of the attachment body 13. A power cord 18 for connecting to a commercial power source (not shown) and a connection cord 19 for supplying power to the lamp 9 are drawn out from the circuit housing 4. The connection cord 19 is connected from the circuit housing 4 to the base portion 5, and extends from the base portion 5 to the lamp 9 through the inside of the support column 7 and the arm portion 8. The power cord 18 and the connection cord 19 are drawn downward from the circuit housing 4. The mounting body 13 to which the circuit housing 4 is mounted is, as described above, the screw of the screw body 14 by the through holes 13D and 13E formed in the upper horizontal piece 13A and the lower horizontal piece 13B, respectively. Since it is pivotally supported by the shaft 15, the mounting body 13, and by extension, the circuit housing 4 is stably supported with respect to the clamp 3 by the upper horizontal piece 13A and the lower horizontal piece 13B. . Further, as described above, the upper horizontal piece 13A of the mounting body 13 is located between the upper horizontal piece 12A and the lower horizontal piece 12B of the main fitting 12, and the lower horizontal piece 13B of the mounting body 13 is the main horizontal piece 12B. Since the vertical piece 13C of the mounting body 13 can be formed as long as possible by configuring it so as to be positioned below the lower horizontal piece 12B of the metal fitting 12, the circuit housing 4 is formed with respect to the vertical piece 13C. Thus, the circuit housing 4 is supported more stably with respect to the clamp 3. Further, as described above, the upper horizontal piece 13A of the mounting body 13 is located immediately below the fastening body 17, and the lower horizontal piece 13B of the mounting body 13 is placed on the upper surface of the knob portion 16. Thus, since the mounting body 13 is configured to hardly move in the vertical direction with respect to the screw body 14, the circuit housing 4 fixed to the mounting body 13 also hardly moves in the vertical direction. The circuit casing 4 is supported more stably with respect to the clamp 3. Further, as described above, in the state where the vertical piece 13C of the mounting body 13 is substantially parallel to the screw shaft 15, that is, the clamp 3 is fixed to the top plate D of the desk, the vertical piece 13C is substantially vertical. Thus, the circuit housing 4 fixed to the vertical piece C is also substantially vertical.

  Next, the operation of this embodiment will be described. First, the user picks the knob 16 of the screw body 14 of the clamp 3 and turns it in the loosening direction, so that the distance between the tightening body 17 of the screw body 14 and the upper horizontal piece 12A of the main metal fitting 12 is as follows. It is expanded so as to be larger than the thickness of the table top D of the desk. Then, the top plate D of the desk is sandwiched between the upper horizontal piece 12A of the main metal fitting 12 and the fastening body 17 of the screw body 14 which are widened as described above, and the clamping portion 16 is pinched to tighten the direction. The top table D of the desk is fastened by the upper horizontal piece 12A and the tightening body 17, whereby the clamp 3 and eventually the table lamp 1 are fixed to the table top D of the table. Then, a power plug (not shown) provided at the tip of the power cord 18 is inserted into a commercial power source (not shown), and the switch 6 is operated to connect the connection cord 19 from a lighting circuit (not shown) in the circuit housing 4. Then, the light source 11 of the lamp 9 is turned on.

  As described above, since the attachment body 13 is pivotally supported with respect to the screw shaft 15, the attachment body 13, and thus the circuit housing 4 attached to the attachment body 13 is Regardless of the rotation of the screw body 14, the mounting body 13 can be disposed at a free position within the rotation range. Accordingly, when the amount of protrusion in the horizontal direction of the table top D of the desk to which the clamp 3 is fixed is sufficiently large, the mounting body 13 and the circuit housing 4 are arranged at the position of FIG. The circuit housing 4 can be completely hidden below the top plate D of the desk. Further, in this state, the circuit casing 4 does not protrude from the back surface of the vertical piece 12D of the main metal fitting 12, so that the edge of the desk top plate D between the edge to which the clamp 3 is attached and the wall surface or partition. Since it is sufficient to provide a gap that is slightly larger than the thickness of the vertical piece 12D of the main metal fitting 12 and the thickness of the connection cord 19, the top plate D of the desk to which the clamp 3 of the desk lamp 1 is attached. The edge can be close enough to the wall or partition. On the other hand, when the amount of protrusion in the horizontal direction of the table top D of the desk to which the clamp 3 is fixed is relatively small, if the mounting body 13 and the circuit housing 4 are arranged at the position of FIG. The case 4 may come into contact with a portion other than the top plate D of the desk, and the top top plate D of the desk cannot be sandwiched between the upper horizontal piece 12A and the fastening body 17. In this case, by arranging the attachment body 13 and the circuit housing 4 at the position shown in FIG. 4A or 4C, the circuit housing 4 is prevented from coming into contact with a portion other than the top plate D of the desk. Therefore, even if the amount of protrusion of the table top D in the horizontal direction is relatively small, the clamp 3 can be fixed to the table top D of the desk. Even in this case, the circuit housing 4 does not protrude greatly from the back surface of the vertical piece 12D of the main bracket 12 of the clamp 3, so that the edge of the table top D of the desk to which the clamp 3 of the desk lamp 1 is attached. Can be sufficiently close to the wall or partition. Note that the power cord 18 and the connection cord 19 are drawn downward from the circuit housing 4 regardless of the position of the circuit housing 4 in FIGS. 4A to 4C. It is possible to prevent these cords 18 and 19 from coming into contact with the top plate D of the desk and getting in the way.

In the table lamp 1, a lighting circuit as an electric circuit or an electronic circuit for lighting the lamp 9 of the table lamp body 2 is incorporated in a circuit housing 4 provided independently of the table lamp body 2, By attaching the circuit casing 4 to the clamp, the desk lamp body 2 itself can be made slim, and by attaching the circuit casing 4 to the clamp 3, the circuit casing 4 Can be placed in an inconspicuous position.

  Further, according to the present invention, the clamp 3 includes a substantially U-shaped main metal fitting 12, a screw body 14 attached by screwing into a screw hole 12C formed in a lower horizontal piece 12B of the main metal fitting 12, The main body 12 is a separate body and is configured by an attachment body 13 that is pivotally attached to the screw body 14 and the circuit housing 4 is not attached to the main body 12 but to the attachment body 13. Since the circuit housing 4 can be prevented from protruding rearward of the clamp 3, the top plate D of the desk to which the clamp 3 is attached can be brought close to the wall. When the mounting body 13 to which the circuit housing 4 is mounted is rotated around the axis of the screw body 14, the amount of protrusion of the desk top plate D in the horizontal direction is relatively small even when it is sufficiently large. However, the clamp 3 can be fixed to the top plate D of the desk. It is.

  Further, in the present invention, through holes 13D and 13E are formed in the upper horizontal piece 13A and the lower horizontal piece 13B of the substantially U-shaped mounting body 13, respectively, and the screw body 14 is passed through these through holes 13D and 13E. Thus, the mounting body 13 to which the circuit housing 4 is mounted can be stabilized by pivotally supporting the mounting body 13.

  Further, according to the present invention, the upper horizontal piece 13A of the attachment body 13 is positioned between the upper horizontal piece 12A and the lower horizontal piece 12B of the main metal fitting 12, and the lower horizontal piece 13B of the attachment body 13 is attached to the main metal fitting 12. The mounting body 13 can be configured by allowing the screw shaft 15 of the screw body 14 to pass through the through hole 13E, the screw hole 12C, and the through hole 13D while being positioned below the lower horizontal piece 12B. Since it can be formed as large as possible, the mounting body 13 and, by extension, the circuit housing 4 fixed to the mounting body 13 can be made more stable.

  The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the gist of the invention. For example, in the above embodiment, the circuit casing is a vertical piece of the mounting body. However, it is only necessary that the circuit housing is attached to the attachment body, for example, the circuit housing is attached to the lower horizontal piece of the attachment body. It may also be suspended from the mounting body.
