DETAILED DESCRIPTION

[0036] The present subject matter pertains to improved approaches for a folding table with adjustable legs and heights. Embodiments of the present subject matter are discussed below with reference to FIGS. 1-10.

[0037] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present subject matter. It will be apparent, however, to one skilled in the art that the present subject matter may be practiced without some of these specific details. In addition, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. Moreover, these examples should not be construed in a limiting sense as they are merely intended to provide examples of embodiments of the subject matter rather than to provide an exhaustive list of all possible implementations. In other instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the details of the disclosed features of various described embodiments.

[0038] The present subject matter will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0039] The schematic diagrams shown in FIGS. 1 to 6 represent the foldable leg frame in this embodiment. The quickly height-adjustable foldable leg frame in this embodiment mainly includes a first table leg 1, a second table leg 2, a first adjustment bar 3, a second adjustment bar 4, a first support bar 5, a second support bar 6, and a locking mechanism 7, among others.

[0040] Referring to FIGS. 1 to 3, the first adjustment bar 3 is installed at the bottom end of the first table leg 1 and can flip up and down relative to the first table leg 1 to achieve height adjustment. The second adjustment bar 4 is installed at the bottom end of the second table leg 2 and can flip up and down relative to the second table leg 2 to achieve height adjustment. The first end of the first support bar 5 is hinged to the first adjustment bar 3, and the first end of the second support bar 6 is hinged to the second adjustment bar 4. Additionally, the second ends of the first adjustment bar 3 and the second adjustment bar 4 are hinged to each other and can rotate relative to each other. When the first adjustment bar 3 and the second adjustment bar 4 both flip downward to a vertical position, causing the foldable leg frame to increase in height, the first support bar 5 and the second support bar 6 can rotate relative to each other into a straight-line state and jointly support between the first adjustment bar 3 and the second adjustment bar 4 to form a stable structure. Additionally, a locking mechanism 7 is provided between the first support bar 5 and the second support bar 6 to ensure that they always remain in a straight-line state.

[0041] To allow the first adjustment bar 3 and the second adjustment bar 4 to be better hinged at the bottom of the first table leg 1 and the second table leg 2, and to ensure that both the first adjustment bar 3 and the second adjustment bar 4 can be timely restricted after rotating to a vertical position, referring to FIGS. 4 and 5, in this embodiment, a first installation slot 1a is specially formed at the bottom end of the first table leg 1 to accommodate the first adjustment bar 3 in a hinged manner. The outer side of the first installation slot 1a is provided with a first side wall 1b that limits the first adjustment bar 3 from rotating outward after flipping to a vertical state. A first hinge hole 1c that transversely penetrates the first installation slot 1a is also provided on the first table leg 1 for hinging the first adjustment bar 3. The bottom end of the second table leg 2 is also formed with a second installation slot 2a to accommodate the second adjustment bar 4 in a hinged manner. The outer side of the second installation slot 2a is provided with a second side wall 2b that limits the second adjustment bar 4 from rotating outward after flipping to a vertical state. A second hinge hole 2c that transversely penetrates the second installation slot 2a is also provided on the second table leg 2 for hinging the second adjustment bar 4.

[0042] Next, to ensure that the first adjustment bar 3 and the second adjustment bar 4 can be timely restricted after rotating to a horizontal state, referring to FIGS. 4 and 5, in this embodiment, the inner side of the first installation slot 1a is specifically formed with a first limit section 1d that restricts the first adjustment bar 3 from continuing to rotate inward after flipping to a horizontal state. Similarly, the inner side of the second installation slot 2a is formed with a second limit section 2d that restricts the second adjustment bar 4 from continuing to rotate inward after flipping to a horizontal state.

[0043] Additionally, to enable better hinging between the first support bar 5 and the second support bar 6 while also allowing them to restrict each other after rotating to a set position, referring to FIGS. 5 and 6, in this embodiment, the second end of the first support bar 5 is formed with a third installation slot 5a to accommodate the second end of the second support bar 6 in a hinged manner. The bottom of the third installation slot 5a is provided with a bottom wall 5b that limits the second support bar 6 from continuing to rotate after reaching a horizontal state. Additionally, a third hinge hole 5c that transversely penetrates the third installation slot 5a is provided on the first support bar 5 for hinging the second support bar 6. A fourth hinge hole 6a that matches the third hinge hole 5c is also provided on the second support bar 6. A pin shaft 6b is inserted through the third hinge hole 5c and the fourth hinge hole 6a, enabling the first support bar 5 and the second support bar 6 to be rotatably hinged together.

[0044] Furthermore, to optimize the overall structure of the locking mechanism 7 and ensure that it can better lock the first support bar 5 and the second support bar 6 in a straight-line state, referring to FIG. 6, the locking mechanism 7 includes a limit slot 7a provided on the end face of the second end of the first support bar 5, a limit pin 7b that is movably arranged on the second support bar 6 and can be embedded in the limit slot 7a, and a reset component 7c that drives the limit pin 7b to always move toward the limit slot 7a. When both the first adjustment bar 3 and the second adjustment bar 4 flip to a vertical state, the limit pin 7b can be embedded and positioned in the limit slot 7a, ensuring that the first support bar 5 and the second support bar 6 always remain in a straight-line state.

[0045] Meanwhile, to allow the limit pin 7b to slide more smoothly along the second support bar 6, referring to FIG. 6, in this embodiment, the second support bar 6 is also transversely provided with a horizontal slot 7d that allows the limit pin 7b to move back and forth. The reset component 7c is a tension spring, with both ends respectively connected to the limit pin 7b and the pin shaft 6b.

[0046] In this embodiment, to enable better fixation between the first table leg 1 and the second table leg 2, referring to FIG. 1, a horizontal bar 8 is provided between the first table leg 1 and the second table leg 2 to secure them together.

[0047] Additionally, this embodiment also provides a folding table, as specifically shown in FIGS. 7 to 10. The folding table includes a tabletop 9 and a foldable leg frame. The tabletop 9 can be a conventional dual-panel tabletop or a single integrated tabletop. The foldable leg frame is hingedly installed at the bottom of the tabletop 9 and can form both a vertical support state and a horizontal folded state. FIG. 7 shows the structural schematic of the folding table with the tabletop in a raised state, while FIG. 8 shows the structural schematic of the folding table with the tabletop in a lowered state.

[0048] In this embodiment, to allow the tabletop 9 to be quickly folded for convenient portability, referring to FIGS. 9 and 10, the tabletop 9 includes a first tabletop 91 and a second tabletop 92 that can rotate relative to each other to form an expanded state or a folded state. The bottom of both the first tabletop 91 and the second tabletop 92 is provided with the aforementioned foldable leg frame. Additionally, a support mechanism 9a is provided between the foldable leg frame and the bottom of the first tabletop 91 and second tabletop 92 to maintain the foldable leg frame in a vertical state. A locking device 9b is also provided between the first tabletop 91 and the second tabletop 92 to maintain the expanded state.

[0049] In this embodiment, to ensure that the folding table maintains good strength and stability while reducing costs, referring to FIG. 9, the first tabletop 91 and the second tabletop 92 are both injection-molded panels. The bottom of both the first tabletop 91 and the second tabletop 92 is provided with a frame 9c, which is embedded along the outer edges of the first tabletop 91 and the second tabletop 92. The frame 9c is primarily made of high-strength materials such as metal to enhance the overall strength of the first tabletop 91 and the second tabletop 92. The first table leg 1 and the second table leg 2 are hingedly installed on the frame 9c, and the support mechanism 9a is positioned between the frame 9c and the foldable leg frame to provide support.

[0050] Additionally, in this embodiment, by setting a first adjustment bar 3 at the bottom end of the first table leg 1, which can flip up and down relative to the first table leg 1 to achieve height adjustment, and a second adjustment bar 4 at the bottom end of the second table leg 2, which can flip up and down relative to the second table leg 2 to achieve height adjustment, and by further setting a first support bar 5 with one end hinged to the first adjustment bar 3 and a second support bar 6 with one end hinged to the second adjustment bar 4, as well as hinging the second ends of the first adjustment bar 3 and the second adjustment bar 4 to each other so that they can rotate relative to each other, when it is necessary to increase the height of the foldable leg frame, it can be quickly increased simply by flipping the first adjustment bar 3 and the second adjustment bar 4 outward simultaneously to a vertical state. Since the first support bar 5 and the second support bar 6 can also rotate synchronously into a straight-line state after the first adjustment bar 3 and the second adjustment bar 4 rotate to the vertical state, they can jointly support between the first adjustment bar 3 and the second adjustment bar 4, allowing the first adjustment bar 3 and the second adjustment bar 4 to form a stable supporting structure. Additionally, by providing a locking mechanism 7 between the first support bar 5 and the second support bar 6 that ensures the first support bar 5 and the second support bar 6 always remain in a straight-line state, the stability of the first adjustment bar 3 and the second adjustment bar 4 under load-bearing conditions is further enhanced. As a result, while enabling the foldable leg frame to be quickly increased in height, it also ensures that the foldable leg frame maintains good stability, reducing the occurrence of wobbling when the table is in use. One more point: To achieve better compatibility and facilitate individual shaping, the first table leg 1, the second table leg 2, the first adjustment bar 3, the second adjustment bar 4, the first support bar 5, and the second support bar 6 are all made of square tubes.
