Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a desk lamp with a flexible support.

[Conventional technology]

FIG. 5 is a perspective view of a conventional desk lamp shown in, for example, Japanese Utility Model Application Publication No. 57-45709.
In the figure, 1 is a main body consisting of a base 2 and a prop 3 erected on the base 2, 4 is attached to the prop 3 of the main body 1 at one end, and has a shade 5 on the other end. The supporting column is made up of wire rods with two types of spring properties wound into a coil shape, and is flexible so that the position of the shade 5 can be varied. 6 is a lamp installed inside the shade 5, and 7 is a connecting part.

[Problem that the invention attempts to solve]

However, in the conventional tabletop desk lamp as described above, when an attempt is made to move the position of the shade 2 in the vertical direction, the operating force is concentrated and applied to the connecting portion 7 as a bending force. For this reason,
When used for a long time, the connecting portion 7 has the problem of being deformed or damaged due to the repeated bending force applied thereto.

This invention was made in order to solve these problems, and aims to provide a desk lamp that can effectively prevent deformation and damage of the communication part 7 while maintaining the operating range of the conventional shade 5. purpose.

[Means for solving problems]

The desk lamp according to this invention has a flexible support that connects the lamp body with the main body, which is fixed to the main body so that the axis of the support is tilted backwards with respect to the reference plane of the main body. It is something.

[Effect]

In this invention, since the flexible support is fixed and tilted backwards with respect to the main body, the bending force generated when the shade moves in the vertical direction is distributed and applied to the connecting part, causing deformation of the connecting part and Damage is prevented.

〔Example〕

Figure 1 is a side view of an embodiment in which this invention is applied to a tabletop desk lamp that uses a single-end fluorescent lamp and has a shade rotation mechanism separate from the flexible support. FIG. 3 is a sectional view showing a support portion of the embodiment. In these figures, 1
The main body consists of a flat base 2, which houses a stabilizer (not shown), etc., and is erected at an angle of about 65° rearward with respect to the base 2. There is. Reference numeral 4 designates a flexible support column, one end of which is fixed inside the upper end of the support base 3 via a connection pipe 13, and the other end thereof similarly connected to the shade 5 via a connection pipe 14. In normal use, this support 4 is bent in the opposite direction to the inclination of the support 3 to support the shade 5, but when extended linearly, its axis is forms a slope similar to the slope of .
Note that 8 is a rotating part that allows the shade 5 to swing freely; 9;
10 is a designed pipe cover, 11 is a mounting screw,
12 is a reinforcing plate.

In the desk lamp constructed in this way, as shown in FIG. 3, when the shade 5 is moved up and down, the support 4 is bent to change its curvature. The maximum bending force on the strut 4 at each shade position occurs between point a or b on the strut 4 and the connection 7, which intersects a vertical line through the connection 7 supporting the strut 4. That is, the bending force is applied to the connecting portion 7 in a distributed manner. On the other hand, in the case of the conventional desk lamp shown in FIG. 4, the maximum bending force is always applied to the connecting portion 7 when the shade 5 is operated up or down.

[Effect of idea]

As explained above, this invention has the effect of effectively preventing deformation and breakage of the support by using a simple structure in which the support support is tilted rearward with respect to the reference plane of the main body.

[Brief explanation of drawings]

Fig. 1 is a side view showing an embodiment of this invention, Fig. 2 is a cross-sectional view of the support section of this invention, Fig. 3 is a diagram explaining the principle of this invention, and Fig. 4 is a diagram illustrating the principle of a conventional example. The explanatory diagram, FIG. 5, is a side view of a conventional example. In the figure, 1 is a main body, 4 is a support, and 6 is a lamp. Note that the same reference numerals in each figure indicate the same or corresponding parts.
