DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
(12) Referring to
(13) Because the other ends of the two first assembly portions 310 are interconnected and/or the other ends of the two first linking members 510 are interconnected, this enables interconnecting the two first assembly portions 310, the two first linking members 510, the two second linking members 610, the two second supporting members 210, the two first supporting members 110, and the two second assembly portions 410. Hence, rotating either one of the first assembly members 300, the first supporting members 110, the second supporting members 210, the second assembly member 400, the first linking members 510, or the second linking members 610 enables completing folding of the foldable support through the interconnecting configuration. For example, when the first assembly portion 310 is rotatably drawn close to the first supporting members 110, the first linking members 510 are driven and drawn close to the first supporting members 110, the first linking members 510 then drive and draw the second supporting members 210 close to the first supporting members 110, which further draws the second linking members 610 close to the second supporting members 210, as well as rotating and drawing the second assembly portions 410 close to the second supporting members 210, thereby completing the folding action of the foldable support. Accordingly, the above-described configuration enables simplifying the folding process of the foldable support, providing convenient operation thereof.
(14) The sliding range of the first linking members 510 enables limiting the unfolding rotation range of the first supporting members 110 relative to the second supporting members 210. Specifically, during the unfolding process of the first supporting members 110 relative to the second supporting members 210, because the second linking members 610 are hinged to the first linking members 510 positioned on the same side, when the first linking members 510 slide to their limiting positions relative to the first assembly portions 310, the first assembly portions 310 are pulled by the first linking members 510 preventing continue rotation thereof. Furthermore, the first supporting members 110 cannot continue to rotate relative to the second supporting members 210. Hence, the extent to which the first supporting members 110 can rotate and unfold relative to the second supporting members 210 is limited. In the same way, the sliding range of the ends of the second linking members 610 also enables limiting the unfolding rotation range of the first supporting members 110 relative to the second supporting members 210.
(15) Referring to
(16) It is hereby specifically pointed out that the hinge method between the first supporting arm 100 and the second supporting arm 200 can adopt a variety of enabled configurations. For example, referring to

(24) It is understood that in a specific embodiment one can choose not to install the two limiting members 710, but still form a limiting function through interoperation of each of the first slide shafts 511 and the respective inner wall at one end of the first strip-shaped hole 311; or choose to include interoperation of the two limiting members 710 to form a limiting function, and not use interoperation of the first slide shafts 511 and the inner walls at ends of the first strip-shaped hole 311 to form a limiting function.
(25) It is hereby specifically pointed out that the above-described first limiting meta structure 700 can also adopt other configuration modes, such as comprising limiting posts 111 disposed on the first supporting members 110, whereby when the first supporting members 110 are in an unfolded state relative to the second supporting members 210, the limiting posts 111 are positioned below the second supporting members 210 and butt connect therewith. Accordingly, the limiting posts 111 are able to limit the continued rotating unfolding of the first supporting members 110 and the second supporting members 210; moreover, the limiting posts 111 are able to further support the second supporting members 210.

(33) The structure of the first locking device 150 is similar to that of the second locking device 250, and not further detailed herein.
(34) It is hereby specifically pointed out that the first supporting arm 100 can also adopt other configuration modes to achieve adjusting the length of the first supporting arm 100, such as the first supporting members 110 being hollow, with the first supporting arm 100 comprising the first adjustment members 140 able to slidable insert inside the first supporting members 110, and each of the first locking devices 150 is installed between the first adjustment members 140 and the first supporting members 110. Accordingly, sliding the first adjustment members 140 enables adjusting the length of the first supporting arm 100, and after adjusting the length, the first locking devices 150 are used to lock the first adjustment members 140.
(35) It is hereby specifically pointed out that the second supporting arm 200 can also adopt other configuration modes to achieve adjusting the length of the second supporting arm 200, such as the second supporting member 210 being hollow, with the second supporting arm 200 comprising the second adjustment members 240 able to slidable insert inside the second supporting members 210, and each of the second locking devices is installed between the second adjustment members 240 and the second supporting members 210. Accordingly, sliding the second adjustment members 240 enables adjusting the length of the second supporting arm 200, and after adjusting the length, the second locking devices 250 are used to lock the second adjustment members 240.
(36) A second embodiment of the present utility model provides a foldable holder that comprises the above-described foldable support and a holder body (not shown in the drawings), wherein the holder body is mounted between the two first assembly portions 310, that is, one end of the holder body is connected to the two first assembly portions 310, and is able to rotatably unfold or fold along with the first assembly portions 310 relative to the first supporting members 110. The other end of the holder body is connected to the two second assembly portions 410, and is able to rotatably unfold or fold along with the second assembly portions 410 relative to the second supporting members 210. Adopting the above-described configuration for the foldable support enables rotating either one of the first assembly member 300, the first supporting members 110, the second supporting members 210, the second assembly member 400, the first linking members 510, or the second linking members 610, causing the first assembly portions 310 and one end of the holder body to rotate downward from the first supporting members 110 away from one side of the second assembly portions 410, to draw close and fold up towards the first supporting members 110, thereby causing the second assembly portions 410 and the other end of the holder body to rotate downward from the second supporting members 210 away from one side of the first assembly portions 310, to draw close and fold up towards the second supporting members 210. Accordingly, the first supporting members 110 and the second supporting members 210 are mutually rotated and drawn close together, thereby completing the folding action of the foldable support and the holder body. From the above-described structural configuration, the foldable holder provided by the present utility model achieves a simple folding process and convenient operation.
(37) When wanting to use the above-described foldable holder, the user can unfold the foldable support and the holder body, and after use, the holder body and the foldable support can be folded up, facilitating storing away thereof.
(38) During use of the above-described foldable holder, corresponding middle portions of the two ends of the holder body have a tendency to upwardly rotate; however, the first limiting meta structure 700 prevents the first assembly portions 310 and the second assembly portions 410 from upwardly rotating, further limiting upward rotation of the two ends of the holder body, thereby enabling the holder body and the foldable support to maintain an unfolded state. It is important to explain that a second limiting meta structure can also be installed between the two ends of the holder body and the middle portions thereof, wherein the second limiting meta structure can limit upward rotation and folding of the two ends of the holder body. Furthermore, through the limitation of the rotation range of the two ends of the holder body, the unfolding rotation range of the first supporting members 110 relative to the second supporting members 210 enables the holder body and the foldable support to maintain an unfolded state. Accordingly, the above-described first limiting meta structure 700 can be omitted.
(39) A subcontracted embodiment of the present utility model provides a foldable bed, which comprises the above-described foldable support and a bed body (not shown in the drawings), wherein one end of the bed body is connected to the two first assembly portions 310, and is able to rotatably unfold or fold along with the first assembly portions 310 relative to the first supporting members 110, and the other end of the bed body is connected to the two second assembly portions 410, and is able to rotatably unfold or fold along with the second assembly portions 410 relative to the second supporting members 210. Adopting the above-described configuration for the foldable support, enables rotating either one of the first assembly member 300, the first supporting members 110, the second supporting members 210, the second assembly member 400, the first linking members 510, or the second linking members 610, causing the first assembly portions 310 and one end of the bed body to rotate downward from the first supporting members 110 away from one side of the second assembly portions 410, to draw close and fold up towards the first supporting members 110, and causing the second assembly portions 410 and the other end of the bed body to rotate downward from the second supporting members 210 away from one side of the first assembly portions 310, to draw close and fold up towards the second supporting members 210. The first supporting members 110 and the second supporting members 210 are mutually rotated and drawn close together, thereby completing the folding action of the foldable support and the bed body. From the above-described structural configuration, the foldable bed provided by the present utility model achieves a simple folding process and convenient operation.
(40) When wanting to use the above-described foldable bed, the user can unfold the foldable support and the bed body, and after use, the bed body and the foldable support can be folded up, facilitating storing away thereof.
