This application claims priority of Taiwanese Patent Application No. 108119703, filed on Jun. 6, 2019.
The disclosure relates to an extension arm support device, and more particularly to an extension arm support device having at least one arm removably connected with an upright post to adjust an angular position of the arm.

Therefore, an object of the disclosure is to provide an extension arm support device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, an extension arm support device includes a support unit, an adapting unit and an extension arm unit. The support unit includes an upright post which extends along an axis. The adapting unit includes an adaptor module which is sleeved around the upright post. The adaptor module has a surrounding wall which surrounds the upright post, and a plurality of anchored portions which are disposed on the surrounding wall and angularly displaced from each other about the axis. Each of the anchored portions has at least one anchored rail which extends in an axial direction parallel to the axis. The extension arm unit includes at least one extension arm which extends in a lengthwise direction radial to the axis to terminate at an anchoring portion. The anchoring portion has an end wall which faces the anchored portions, and at least one anchoring member which is disposed on the end wall and which is slidable along and engaged with the anchored rail in the axial direction such that the extension arm is removably connected to the adaptor module.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:

The support unit 2 includes a base seat 22 and an upright post 21 which extends from the base seat 22 along an axis (X). With reference to

With reference to
In this embodiment, the anchoring member 313 is slidably inserted into the corresponding anchored rail 621 in the axial direction to have an upper surface immerged in the anchored rail 621. With the anchored rail 621 having the larger and smaller width groove portions 622, 623 for respectively receiving the head and neck portions 315, 314, the anchoring member 313 is slidably inserted in the anchored rail 621 in the axial direction and is restricted from radial movement relative to the axis (X). Moreover, the smaller width groove portion 623 has, in the axial direction, a length which is smaller than that of the larger width groove portion 622. Therefore, the radial movement of the anchoring member 313 can be further prevented.
In this embodiment, the upper opening 624 has a T-shaped cross-section such that the anchoring member 313 has a T-shaped cross-section.
Alternatively, in alternative modified forms, the numbers of the surrounding wall 61, of the anchored portions 62, and of the anchored rails 621 of each anchored portion 62, and the shape of cross-section of the upper opening 624 may be those illustrated in the following list and
Moreover, the upper opening 624 may alternatively have a V-shaped cross-section. In other modified embodiments, as shown in

As illustrated, with the anchored portions 62 of the adaptor module 6 and the corresponding anchoring members 313 of the extension arm 31 slidable along and engaged with the anchored portions 62 in the axial direction, the extension arm 31 is removably connected to the adaptor module 6 to adjust the angular position thereof to the upright post 21 without the need to remove the adaptor module 6 from the upright post 21.
While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
