Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a desk lamp having a structure in which a tube-shaped decoration is covered with a flexible support and held by a clamp. The present invention relates to a support device for a desk lamp, which is suitable for easily determining the dimensions for fitting with a clamp.

[Background of the idea]

As shown in FIGS. 1 and 2, a conventional single flexible support desk lamp that holds a flexible support with a clamp has a pipe 5 exposed and caulked to the lower part of the flexible support 4.
is inserted into the insertion hole 10 of the clamp 6 and held. Generally, the clamp 6 is made of die-cast metal, so if the dimensions of the pipe 5 and the insertion hole 10 become even slightly tight, there is a drawback that it cannot be inserted all the way. On the other hand, since the flexible support 4 is exposed, the color and shape of the surface are limited in terms of design.

In the present invention, in order to eliminate restrictions on design, as shown in FIG. 3, a tube 12 is placed over a flexible support 11 having the same structure as in FIG. 1, so that changes in design can be easily made. At that time, it is necessary to take care not to expose the cut surface of the lower end of the tube, but even if you try to apply it directly to the top surface of the clamp 6, the cord support body 7 will become an obstacle, as shown in Figure 2. Well, at this rate, it's tube 12.
The supporting end (cut surface) is exposed below. As a conventional method to improve this point, as shown in FIG. 4, there is a method in which a cover 15 made of metal or the like with a two-stage throttle is attached to the pipe 14 with screws 16, and the cut part of the tube 12 is inserted. Clamp 6 insertion hole 1
A gap must be provided between the upper end of the cover 15 and the lower end of the cover 15, resulting in an unsightly appearance.

Furthermore, in the case of the structure shown in FIGS. 1 and 2 or the structure shown in FIG. The insertion hole 10 also has to be different, and there is also the disadvantage that the insertion hole of the clamp 6 cannot be shared each time the model is changed.

[Purpose of invention]

The purpose of this invention is to use a fixing device for resin molded products.
It serves as a stopper and cover for the cut section of the tube, making it easier to handle the cut section of the tube, and also covers the end of the support as one piece. By changing the wall thickness of this fixing device, the fitting size for the insertion hole can be easily adjusted. Moreover, it is possible to always share an insertion hole of the same diameter regardless of a change in the outer diameter of the end portion (insertion portion) of the column.

[Summary of the idea]

Since the lower end of the tube (cutting part) and the end of the strut are close to each other, this invention uses an integrated resin that doubles as a cover and stopper for the lower end of the tube and also covers the end of the strut (insertion part). By covering the molded product over the support column, the appearance of the lower end of the tube and the fitting size with the insertion hole can be easily adjusted.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 5 and 6.

In FIG. 5, the main body of the flexible support 11 is fixed to an end pipe 14, and the flexible support 11 is covered with a decorative tube 12.

A pipe-shaped fixture 13 is inserted into the flexible strut 11 and tube 12 from the end of the strut.

The inner diameter of the upper opening of the fixture 13 is the tube 1
A step-shaped stopper 21 is provided at a certain depth on the inner surface of the stopper 21 to restrict the insertion size of the tube 12, so that the lower end of the tube 12 can be pushed downward in the use state. Since it does not shift and the lower end is completely covered, the appearance can be easily treated. Furthermore, since the fixture 13 will come off downward if left as is, the cord support 7 is used as a stopper. That is, with the end pipe 14 inserted into the fixture 13, the cord 8 is passed through the lower notch hole 19 of the fixture 13, further passes through the slit 18, and is passed through the upper notch hole 17 into the cord support 7.
is rotated and fixed in the notch of the pipe 14. Therefore, the upper end of the upper cutout hole 17 of the fixture 13 hits the upper end of the cord support 7,
This serves as a stopper for the fixture 13.

Further, the thickness of the lower end portion of the fixture, for example, the clamp 6, that is, the insertion portion, is set based on the dimensional difference between the outer diameter of the end pipe 14 and the inner diameter of the insertion hole 10 of the clamp 6. As a result, even if the outer diameter of the tube 12 is changed in terms of design and the outer diameter of the end pipe 14 is changed as a result, it is only necessary to change the inner diameter of the insertion part 20 of the fixture 13, and the difference in the clamp 6 can be changed each time. Common use can be achieved without changing the diameter of the insertion hole 10.

In addition, since the fitting dimension between the insertion hole 10 of the clamp 6 and the insertion part 20 of the fixture 13 can be adjusted by the diameter of the insertion part 20 of the fixture 13, the clamp This is easier than adjusting the dimensions using the insertion hole 10 of No. 6.

[Effect of idea]

In the present invention, the cut surface of the lower end of the tube is covered with a pipe-shaped fixture to facilitate appearance treatment. This fixture also serves as a tube stopper. Further, this same fixture can be used to adjust the fitting size with the insertion hole of the fixture. moreover,
Even if the dimensions of the support column change, it is sufficient to adjust the diameter of the lower end (insertion part) of the fixture. For this reason,
There is no need to replace the fixture with one of a different size.
