BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk stand used to illuminate a desk placed on a desk, and more particularly, to a lamp which is formed by connecting an end of a horizontally long lamp to an upper end of an arm. In a cantilevered manner on a desk stand.

[0002]

2. Description of the Related Art In a conventional desk stand, FIG.
As shown in FIG. 2, the lower end of the arm 2 is rotatably connected to the base 1 by the swing unit 3, and the shade 4 of the lamp is connected to the swing unit 5 at the center of the shade 4 at the upper end of the arm 2. It is connected rotatably. The direction of the shade 4 can be changed by rotating the shade 4 as shown by an arrow a, and the tilt angle can be adjusted by rotating the shade 4 as shown by an arrow b. The angle of the arm 2 can be adjusted back and forth by rotating the arm 2 as shown by an arrow c.

[0003]

In the above-mentioned conventional desk stand, since the arm 2 is located at the center with respect to the longitudinal direction of the shade 4, the holding force due to the rotation of the shade 4 is balanced in the right and left directions. There was no need to make the vessel 5 larger. However, in order to support the laterally long shade 4 at the end of the shade 4 in a cantilever manner, a large moment is applied to the universal device, so that the holding force of the hinge must be increased, and the size of the universal device increases. Therefore, the appearance of the desk stand may be impaired. The desk stand should preferably be parallel to the desk surface, which is the surface to be illuminated. However, when the shade 4 or the arm 2 is operated in order to adjust the tilt angle or the front-back position, the shade 4 rotates and the shade 4 is rotated. In some cases, the light did not become parallel to the desk surface, and proper light distribution and illuminance could not be obtained.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to fix the direction of rotation of the shade to a position where the shade and the desk top are parallel to each other to fix the desk top. It can be illuminated uniformly, and it can be compact when not in use by turning and folding the shade, and the stopper mechanism ensures the shade.
Despite the structure that can be fixed to
Is with a can be reduced, to provide a desk stand is Ru can better appearance.

[0005]

In order to achieve the above object, a desk stand according to the present invention connects a lower end of an arm 2 to a base 1 placed on a desk so that the arm 2 can rotate back and forth. A desk stand in which a shade 4 of a lamp having a long length in the direction is connected to the upper end of the arm 2 at the longitudinal end of the shade 4 and is rotatably connected to the upper end of the arm 2 so that the shade 2 can be tilted. , A swivel 6 for rotating the shade 4 in the folding direction in addition to sliding the shade 4 in the tilting operation direction between the shade 4 and the upper end of the arm 2.
And a stopper mechanism capable of fixing the shade 4 at a position where the shade 4 can be illuminated on the desk surface when it is horizontal, and at a position where the shade 4 is rotated upward or downward to be in a folded position that does not interfere with the shade. 6 and the universal device 6 is attached to the arm 2
And the arm 2 side attached to the arm 2 side

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 3, a lamp is formed by accommodating a lamp 9 in a shade 4. FIG. The sail 4 is composed of an upper shade 4a and a lower shade 4b. A socket 8 is mounted in the upper shade 4a, a lamp 9 is mounted on the socket 8, and the lamp 9 is connected to the upper shade 4a and the lower shade 4b. It is stored between. A fastening member 10 is attached to the seed 4 with a mounting screw.
The universal device 3 is attached to the fastening fitting 10 with a thumb screw 11. By loosening the thumb screw 11, the shade 4 can be rotated with respect to the universal device 3 together with the clamp 10, and the tilt angle of the shade 4 can be adjusted. Can be fixed so as not to rotate.

A universal unit 6 is fitted on the back of the universal unit 3,
The universal unit 6 is attached to the universal unit 3 with a thumb screw 12. By loosening the thumbscrew 12, the universal device 3 can be rotated with respect to the universal device 6. By tightening the thumbscrew 12, the universal device 3 can be rotated with respect to the universal device 6.
Can be fixed. The universal device 6 is attached to the upper end of the arm 2 with the attachment screw 13.
The universal device 5 is attached to the lower end of the device with attachment screws 14.

The base 1 includes an upper base 1a and a lower base 1b. Attachment screw 15 to lower base 1b
The universal bracket 5 at the lower end of the arm 2 is attached to the clamp 16 with a thumb screw 17. By loosening the thumbscrew 17, the arm 2 can be rotated back and forth together with the universal device 5 with respect to the fastening bracket 16 and the base 1.
The arm 2 can be fixed to the base 1 by tightening. An inverter block 18 is disposed in the base 1, and the inverter block 18 is attached to a locking support 19 of the lower base 1 b.
