Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a universal arm stand that is used by being attached to a desk or the like.

[Prior Art] FIG. 3 shows a conventional free-form arm stand, for example, as shown in Japanese Utility Model Laid-Open No. 62-124710.

In the figure, 1 is an arm support fixed to a desk D, and 2 is an arm which is rotatably raised by inserting a lower end shaft 3a into a tube 1a of the arm support 1. This arm 2
The first arm 3 and the second arm 4 are the first joint portion 7, the second arm 4 and the third arm 5 are the second joint portion 8, and the third arm 5
And the fourth arm 6 are connected by a third joint portion 9 so as to be bendable. Shaft of the lower end of the arm 2 described above
3a is provided on the first arm 3. 10 is arm 2
, A sade rotatably attached to the fourth arm 6, 11 is a switch mounted in the sade 10, and 11a is a push button of the switch 10 protruding to the side of the sade 10. 7 and 8 are light bulbs and sockets installed in the shade 10.

[Problems to be solved by the device]

Since the conventional free-form arm stand is configured as described above, the push button 11a must be pressed when turning on or off. However, the push button 11a does not operate well because the arm 2 bends at the joints 7 to 9 or rotates around the lower end shaft portion 3a and the shade 10 escapes only by pushing with a fingertip. In order to reliably push the push button 11a, for example, as shown in FIG. 4, the push button had to be pushed while holding the shade 10 by hand. For this reason, the conventional arm stand has a problem that the operability of the switch is poor.

In addition, the push button 11
Since a projects from the shade 10, this is an obstacle to obtaining a simple shade with less unevenness, and there is a problem in that its appearance quality is degraded.

Of course, even with the same push button stand, as shown in FIG. 5, there is a stand provided with a handle 13 on the shade 12 and a push button 14 attached thereto in order to facilitate the button operation. However, with this structure, the handle 13 and the push button 14 greatly protruded from the shade 12, which was fatal in terms of the appearance quality of the shade described above.

The present invention has been made to solve such a conventional problem, and provides a flexible arm sundado having a sade with good operability of a switch, a small unevenness, a simple and excellent appearance quality. The purpose is to

[Means for Solving the Problems]

A free-standing arm stand according to the present invention comprises an arm support portion fixed to an end of a desk, a bendable arm rotatably raised and mounted on the arm support portion, and a pivotable arm end portion. In a free-form arm stand which is attached so that it can be composed of an upper shade and a lower shade, a sensor unit of a touch switch is provided on the shade, and this sensor unit is provided between the upper and lower shades. While sandwiched, the exposed surface of the sensor portion and the outer surface of the shade are flush with each other.

[Action]

In the flexible arm stand, the sensor part of the touch switch is provided on the shade, and the sensor part is sandwiched between the upper and lower shades, and the exposed surface of the sensor part and the outer surface of the shade are flush with each other. As a result, the assembling of the shade and the sensor part has been improved, and the outer surface of the shade is not made uneven, and the one-touch operation of lightly touching the exposed surface of the sensor part with one finger, without grasping the shade , The lamp can be turned on or off.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numeral 21 denotes an arm supporting portion, which is composed of a frame portion 21b fixed to the desk D with screws 21a and a pipe portion 21c projectingly provided on the upper surface thereof. Reference numeral 22 denotes an arm which is rotatably raised by inserting a lower end shaft portion 23a into a tube portion 21c of the arm support portion 21. The arm 22 includes a first arm 23 and a second prismatic second tube.
The arm 24 can be bent at the first joint portion 27, the second arm 24 and the prismatic third arm 25 at the second joint portion 28, and the third arm 25 and the fourth arm 26 at the third joint portion 29, respectively. It is configured by connecting to. The shaft portion 23a at the lower end of the arm 22 described above is provided on the first arm 23.

Reference numeral 30 denotes a shade that is rotatably attached to the tip of the arm 22, that is, the fourth arm 26. This sade 30 is an upper sade 30
The sensor part 31 of the touch switch is sandwiched between a and the lower shade 30b, and the three parts 30a, 30b, 31 are integrally assembled.

As shown in FIG. 2, the exposed surface 31a of the sensor unit 31 is incorporated in the shade 30 so as to be flush with the outer surface of the shade 30. 32 and 33 are compact fluorescent lamps and their sockets installed in the shade 30.

34 and 35 are the main parts of the electronic ballast and touch switch incorporated in the second arm 24. The main body part 35 is the second arm.
24, the third arm 25, the fourth arm 26, and a cord 36 passed through the shade 30 are connected to the sensor unit 31.

Next, the operation will be described.

Since the sensor part 31 of the touch switch provided on the shade 30 operates by simply touching it lightly with a finger, as described above, the sensor part 31 does not protrude from the shade 30, that is, the exposed surface 31a of the sensor part 31 is the outer shape of the shade 30. It can be incorporated so that it is flush with the surface. Therefore, the shape of the shade 30 is simple with little unevenness, and the appearance quality in terms of design is excellent.

Further, the touch switch can be operated by lightly touching the sensor unit 31 with a finger. Therefore, unlike the conventional case, it is not necessary to operate while holding the shade with the hand, and the operability of the switch is further improved.

[Effect of device]

As described above, according to the present invention, in the flexible arm stand, the sensor portion of the touch switch is provided on the shade, and the sensor portion is sandwiched between the upper shade and the lower shade, and the sensor portion has a front surface. Since the projecting surface and the outer surface of the shade are flush with each other, the assembling property between the shade and the sensor portion is improved, and the outer surface of the shade is not uneven, and the appearance is simple and excellent in appearance quality. In addition, since the lamp can be turned on or off without grasping the shade by one-touch operation with only one finger lightly touching the exposed surface of the sensor part, the angle of the arm changes when the switch operation switch is operated. It is possible to obtain a flexible arm stand with improved lighting performance and operation performance without the movement of the shade changing each time and the reduction of the lighting effect.
