DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk lamp in which an arm is rotatably supported on a base.

[0002]

2. Description of the Related Art In this type of desk lamp, a rotating portion at the lower end of an arm is pivotally supported on a base side so as to be rotatable. It was configured to restrict the rotation of the.

[0003]

However, the above-mentioned prior art has a problem in making the packaging of the desk lamp compact. Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a desk lamp that can be compactly packaged.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a desk lamp in which a rotating portion at the lower end of an arm is rotatably supported on a base, and is provided at the lower end of the rotating portion and protrudes elastically. The convex portion to be brought into contact with the stopper on the base side restricts the rotation of the arm rearward, and a hole for pushing the convex portion into the lower surface of the base to release the contact between the convex portion and the stopper is formed. The provided desk lamp is configured.

[0005]

According to the present invention, during normal use, the rotation of the arm in the rearward direction is restricted, so that the desk lamp can be prevented from falling backward. Then, at the time of packaging, a screwdriver or the like is inserted into a hole on the lower surface of the base, the convex portion is pushed in, the contact between the convex portion and the stopper is released, and the arm is tilted backward.

[0006]

An embodiment of the present invention will be described with reference to the drawings.

This embodiment is a desk lamp in which a pivoting portion 2 at the lower end of an arm 1 is rotatably supported on a base 3 side, and is provided at the lower end of the pivoting portion 2 so as to project by being elastically biased. The protrusion 4 is brought into contact with the stopper 5 on the base 3 to restrict the backward rotation of the arm 1, and the protrusion 4 is pushed into the lower surface of the base 3 to make contact between the protrusion 4 and the stopper 5. A desk lamp provided with a hole 6 for canceling is provided.

More specifically, the protrusion 4 is elastically urged by a coil spring 7 housed in a portion protruding from the lower end of the rotating portion 2 and protrudes. The stopper 5 is configured as a back end surface of a cutout 9 formed at the rear end of the substrate 8 provided in the base 3. Supporting plates 10 and 10 are fixed to the substrate 8, between which the rotating part 2 and the balance spring 11 are pivotally supported. A shade 12 houses a lamp (not shown) on its lower surface.

According to the present embodiment, during normal use, the rearward rotation of the arm 1 is restricted, and the rearward fall of the desk lamp can be prevented. At the time of packaging, a screwdriver or the like is inserted into the hole 6 on the lower surface of the base 3 and the convex portion 4 is pushed in, the contact between the convex portion 4 and the stopper 5 is released, and the arm 1 is tilted backward. Further, when the shade 12 is rotated around two axes along the arm 1, the whole shape becomes thin and long as shown in FIG. 5, and the packaging of the desk lamp can be made compact (the packaging box can be made thin). In use, simply raising the arm 1 causes the tip of the convex portion 4 to slide on the surface of the substrate 8 and get over the stopper 5, which is convenient. Further, the excessive fall of the arm 1 forward is prevented by the side surface of the protruding portion of the rotating portion 2 abutting against the rear wall of the pocket portion 13 at the rear end of the base 3.

[0010]

As described above, according to the present invention, there is an effect that the packaging of the desk lamp can be made compact.

Claims (1)

(57) [Claims] 1. A desk lamp in which a rotating portion at a lower end of an arm is pivotally supported on a base side so as to be rotatable, and a convex portion provided at the lower end of the rotating portion and projected by being elastically biased is provided on the base side. A desk lamp having a hole for abutting against a stopper to restrict rotation of the arm rearward and for pressing the protrusion into the lower surface of the base to release the contact between the protrusion and the stopper.
