[0004] Foldable tables can be used in environments with limited space or multiple uses, such as vehicles. Summary of the Invention

[0005] This disclosure describes an easy-to-operate foldable table.

[0006] According to one aspect of the subject matter described in this application, a foldable table includes: a tabletop; a table frame coupled to the tabletop; a base with a first end hinged to the table frame, the base configured to rotate about a second end of the base, and the base including a support fixing body disposed within the base and coupled to the second end of the base; a locking module disposed in the base, the locking module including a first locking member configured to set a tilt angle of the table frame based on rotation of the table frame by engaging with the support fixing body; and an angle adjustment module disposed in the locking module and configured to adjust the tilt angle of the table frame by disengaging the first locking member from the support fixing body in response to an external force applied to the angle adjustment module.

[0007] Embodiments according to this aspect may include one or more of the following features. For example, the locking module may further include a second locking member configured to secure the table support in the unfolded state by engaging with an end of the table support in response to rotation of the table support in the unfolding direction. In some examples, the second locking member may be connected to a first locking member, and the first locking member may be configured to set the tilt angle of the table support by engaging with the support fixing body at the point in time when the second locking member secures the table support in the unfolded state by engaging with the end of the table support.

[0008] In some embodiments, the angle adjustment module may include a guide configured to guide a second locking member upward in response to an external force, and a first locking member configured to move the bracket fixing body upward in response to the upward movement of the second locking member, thereby separating the first locking member from the bracket fixing body and thus enabling adjustment of the tilt angle of the table bracket.

[0009] In some embodiments, the first locking member may include: a locking plate configured to slide up and down based on rotation of the table support; and a first locking gear formed at the lower end of the locking plate. A second locking gear may be formed at the upper end of the support fixing body, and the first and second locking gears are configured to engage each other based on rotation of the table support in the unfolding direction, thereby setting the tilt angle of the table support.

[0010] In some embodiments, the locking module may further include: a locking connector configured to move within the locking module in response to rotation of the table support; and a first resilient member disposed at the lower end of the locking connector, the locking plate being engaged with the locking connector via the first resilient member. The table support may include a support connector having i) a first end engaged with the lower end of the table support, and ii) a second end supported by the middle portion of the locking connector, and the support connector being configured to press downward against the locking connector in response to rotation of the table support in the unfolding direction, thereby causing the locking plate to move downward.

[0011] In some examples, the second locking member may have: i) a first end with a locking latch configured to engage with an end of the table support; and ii) a second end with a connecting portion configured to connect to a locking plate. In some examples, the locking latch may be configured to engage with an end of the table support in response to downward movement of the locking plate, thereby securing the table support in an unfolded state.

[0012] In some embodiments, the locking module may further include: a housing that forms the shape of the locking module and is fixed in the base; and a second elastic member, via which the locking connector is engaged within the housing and configured to slide within the housing. In some examples, the second elastic member may be configured to be compressed between the housing and the locking connector in response to rotation of the table support in the unfolding direction, while the first elastic member remains in the extended state.

[0013] In some examples, the angle adjustment module may include a guide configured to guide the second locking member upward in response to an external force, and a locking plate configured to move upward in response to the upward movement of the second locking member while compressing the first elastic member, thereby disengaging the first locking gear and the second locking gear from each other.

[0014] In some embodiments, the base may include a connector track disposed therein, the connector track being configured to guide the second end of the support connector to move up and down.

[0015] In some embodiments, the support bracket is integrated into the table housing, and the base and table support are configured to be housed within the table housing. For example, a foldable table can be configured to: i) unfold from the table housing based on the base rotating about the support bracket in the upward direction; and ii) fold into the table housing based on the base rotating about the support bracket in the downward direction.

[0024] One or more embodiments of this disclosure will be described in detail below with reference to the accompanying drawings, and the same or similar parts are given the same reference numerals regardless of the drawing numbers, and will not be described repeatedly.

Figure 3 This is an exploded view of an example of the base of a foldable table. Figure 4 This is a 3D diagram of the base of the foldable table. Figure 5 An example of a table stand is shown.

[0026] In some implementations, reference Figures 1 to 5The foldable table disclosed herein can include a table frame 100, with a tabletop 200 mounted on the table frame 100. The tabletop 200 is connected to a base 300 and hinged to the base 300 in a manner rotatable in a first direction. The tabletop 200 can be configured to rotate about the table frame 100 in a second direction. In some examples, the usability of the tabletop 200 can be expanded by rotating in the second direction. By further rotating in a third direction, the tabletop 200 can be fully unfolded. For example, in an XYZ coordinate system, Figure 2 The table support 100 extends along the X-axis, and the base extends along the Z-axis. Rotation of the table support 100 from the base 300 in a first direction is possible about a Y-axis orthogonal to both the X and Z axes. Rotation of the tabletop 200 from the table support 100 in a second direction is possible about a Z-axis perpendicular to the tabletop 200. Rotation of the tabletop 200 in a third direction can be achieved by folding / unfolding the tabletop 200 about the X-axis. Furthermore, the base 300 is capable of rotation about the X-axis.

[0027] In some examples, the table support 100 is rotatably hinged to a first end of the base 300, and the support fixture 310 is attached to a second end of the base 300. The base 300 provides the tabletop 200 in an unfolded or stowed state by rotating on the support fixture 310. The support fixture 310 is a non-movable or non-rotating component; only the base 300 can rotate about the support fixture 310, as will be described below.

[0028] In some embodiments, the entire foldable table, including the base 300, can be housed in the table housing T, and the support bracket 310 can be attached in a manner that secures it within the table housing T.

[0029] The locking module 500 is installed in the base 300 and engages with the bracket fixing body 310 by the rotation of the table support 100 (e.g., locking, engaging, etc.) to set and fix the angle of the table support 100. Specifically, the locking module 500 includes a first locking member 510, which engages with the bracket fixing body 310 when the table support 100 is unfolded by rotating in a first direction, preventing the base 300 from rotating further and thus fixing the angle of the table support 100.

[0030] An angle adjustment module 600 is configured within the locking module 500. When an external force is applied to the angle adjustment module 600, the first locking member 510 can disengage from the bracket fixing body 310. When the first locking member 510 is disengaged from the bracket fixing body 310, the base 300 becomes capable of rotating in the third direction, thus allowing the user to adjust the angle of the tabletop 200 by adjusting the angle of the table support 100 in the third direction. The angle adjustment module 600 is designed to be easy to operate even when the table is in use. This is because the portion of the angle adjustment module 600 to which external force is applied protrudes outward from the base 300, allowing the user easy access and application of external force.

[0031] In some embodiments, the locking module 500 may further include a second locking member 521, which, when the table support 100 rotates in the unfolding direction, engages with the end of the table support 100 to secure the table support 100 in the unfolded state. The second locking member 521 is configured to engage with the end of the table support 100 and is used to secure the table support 100 when it is fully unfolded. Specifically, when the table support 100 is unfolded to a target angle, the second locking member 521 engages with the end of the table support 100, thereby maintaining the unfolded state. Thus, the table support 100 is less likely to move or fold due to externally applied forces, maintaining a stable unfolded state. The second locking member 521 cooperates with the first locking member 510, so when the tabletop 200 is fully unfolded, the two locking members 510 and 521 enhance the fixation of the tabletop 200. In other words, the first locking member 510 prevents the base 300 from rotating by engaging with the bracket fixing body 310, and the second locking member 521 engages with the end of the table support 100, thereby improving the stability of the entire tabletop 200.

[0032] Figures 6 to 8 The table support is shown unfolded in sequence. (Refer to...) Figures 6 to 8 It can be seen that the first locking member 510 and the second locking member 521 fix the angle and position of the table through interconnection. Specifically, the second locking member 521 is connected to the first locking member 510, and the first locking member 510 can fix the angle of the table support 100 by engaging with the bracket fixing body 310, while the second locking member 521 can fix the table support 100 in the unfolded state by engaging with the end of the table support 100. That is, the first locking member 510 moves downward by rotating the table support 100 in the first direction and engages with the bracket fixing body 310, and the second locking member 521 is connected to the first locking member 510 and moves downward by rotating the table support 100 in the first direction, fixing it to the end of the table support 100, i.e., the locking part 121, thereby fixing the table support 100 in the unfolded state.

[0033] As described above, the first locking member 510 and the second locking member 521 hold the table support in different positions, thus the application of a dual locking mechanism further enhances stability. For example, while the first locking member 510 is engaged with the support fixing body 310, the second locking member 521 additionally engages with the locking portion 121 of the table support 100, thereby achieving a high degree of robustness that cannot be ensured by a single lock. This dual fixing system prevents the tabletop 200 from easily loosening in the event of accidental impact or overload, and ensures user safety and equipment durability.

[0034] Specifically, when subjected to a strong impact (acceleration / deceleration), the locking mechanism of the prior art is unlocked and moves unexpectedly, while according to this disclosure, the table support is firmly restrained by the first locking member, the second locking member and the support fixing body, so that the table can remain in a fixed state even when subjected to a strong impact.

[0035] In some embodiments, the angle adjustment module 600 includes a guide 610 that slides when an external force is applied, causing the second locking member 521 to move upward. When the second locking member 521 moves upward, the first locking member 510 also moves upward, thus separating the first locking member 510 from the bracket fixing body 310 and enabling the adjustment of the angle of the table bracket 100.

[0036] Specifically, the guide 610 is configured to slide when an external force is applied, thus facilitating mechanical operation when the user attempts to change the table angle. For example, the guide 610 may include a protrusion 620, with protrusion recesses 360 and 560 formed in the base 300 and locking module 500 respectively, to allow the protrusion 620 to protrude outward from the base 300. The user can apply an external force to the guide 610 through the protrusion 620 extending from the base 300. The guide 610 has a ramp 630 on one side, so when the guide 610 slides, the second locking member 521 moves upward along the ramp 630 of the guide 610, and the first locking member 510 connected to the second locking member 521 also moves upward along the second locking member 521, thereby disengaging the first locking member 510 from the support fixing body 310. As a result, the base 300 can rotate in a third direction, and the table support 100 can also rotate in a third direction.

[0037] Even when the table support 100 has rotated in the unfolding direction, the first locking member 510 can temporarily separate from the support fixing body 310, as will be described below. That is, the first locking member 510 is temporarily separated from the support fixing body 310, so the table support 100 can enter a state where its angle can be adjusted, and when the angle of the table support 100 is adjusted, the first locking member 510 is fastened to the support fixing body 310 again, thereby fixing the base 300 and the table support 100.

[0038] More specifically, the first locking member 510 and the second locking member 521 included in the locking module 500 are described.

[0039] The first locking member 510 is a mechanism designed to fix the table angle when the table support 100 is unfolded. The first locking member 510 includes a locking plate 511. The first locking member 510 includes a locking plate 511 that slides up and down inside the locking module 500 as the table support 100 rotates, and a first locking gear 511a is formed at the lower end of the locking plate 511. A second locking gear 310b is formed at the upper end of the support fixing body 310, so the angle of the table support 100 is fixed by the meshing of the two gears 511a and 310b. That is, when the table support 100 rotates in the unfolded direction, the locking plate 511 of the first locking member 510 slides downward, thereby engaging the first locking gear 511a and the second locking gear 310b of the support fixing body 310, and the table support 100 is fixed. Conversely, when the table support 100 rotates in the folding direction, the first locking member 510 disengages from the second locking gear 310b, and the base 300 and the table support 100 become rotatable.

[0040] The locking module 500 also includes a locking link 530, which slides within the locking module 500 as the table support 100 rotates. At the lower end 530b of the locking link 530, a locking plate 511 is engaged with the locking link 530 via a first elastic member 512. A first end 150a of the bracket link 150 is engaged with the lower end of the table support 100, and a second end 150b of the bracket link 150 is supported by the middle portion 530c of the locking link 530. When the table support 100 rotates in the unfolded direction, the bracket link 150 presses down on the locking link 530, thereby allowing the locking plate 511 to slide downwards. For example, the first elastic member 512 may include a spring.

[0041] In some examples, the first end 150a of the bracket connector 150 is attached to the lower end of the table support 100, and the second end 150b of the bracket connector 150 is supported by the middle portion 530c of the locking connector 530. That is, the foldable table is designed such that when the table support 100 rotates, the bracket connector 150 can press down on the locking connector 530. When the table support 100 rotates in the unfolded direction, this operation helps the locking plate 511 slide to the correct position by pushing the locking connector 530 downwards. During this process, the first elastic member 512 absorbs the impact, allowing the locking connector 530 to slide smoothly and helping the locking plate 511 to be firmly fixed in the target position. The first elastic member 512 can partially contract and expand, but when the locking plate 511 and the bracket fixing body 310 are engaged with each other, the first elastic member 512 remains in the expanded state. Thus, the table support 100 is fixed.

[0042] An external force can be applied to the angle adjustment module 600 to adjust the angle of the table support 100. That is, referring to... Figures 10 to 11 When an external force is applied to the guide 610 of the angle adjustment module 600 and the guide 610 causes the second locking member 521 to move upward, the locking plate 511 moves upward because it is connected to the second locking member 521. At the same time, the first elastic member 512 contracts and the locking plate 511 separates from the bracket fixing body 310, thereby enabling the base 300 and the table support 100 to rotate upward in the third direction.

[0043] In some embodiments, a link rail 700 is disposed in the base 300 to allow the second end 150b of the bracket connector 150 to slide vertically. The link rail 700 guides the movement of the bracket connector 150 and provides stability and precision during the unfolding and folding of the tabletop 200. The link rail 700 smooths the vertical movement of the bracket connector 150, allowing the user to experience a smooth operation when unfolding or folding the tabletop 200. Because the bracket connector 150 slides stably along the link rail 700, the tabletop 200 moves smoothly and stably, making it easier for the user to operate the tabletop 200.

[0044] Because the second end 150b of the bracket connector 150 slides along the connector track 700, the horizontal and vertical stability of the tabletop 200 is ensured. In other words, the connector track 700 provides support, ensuring that the table's position does not change even if the table vibrates or is subjected to external impacts during use. This is particularly important when the tabletop 200 is used in confined or mobile spaces, increasing the stability of the tabletop 200 in its unfolded state.

[0045] In some embodiments, the second locking member 521 may have a locking latch 521a formed at a first end to engage with the end of the table support 100, and a connecting portion 521b formed at a second end to connect with the locking plate 511.

[0046] Reference Figure 9 A locking latch 521a is formed at the first end of the second locking member 521, which engages with the end of the table support 100. When the table support 100 is unfolded, the locking latch 521a engages stably with the locking portion 121 of the table support 100 to secure the tabletop 200, preventing accidental movement of the tabletop 200. Even under vibrations or external impacts that may occur during use, this engagement keeps the tabletop 200 in a fixed position, thus providing stability for the user.

[0047] A connecting portion 521b is formed at the second end of the second locking member 521 and is connected to the locking plate 511. Thus, the second locking member 521 performs an action that is linked to the movement of the locking plate 511. For example, when the locking plate 511 slides up and down due to an external force, the second locking member 521 also moves up and down together with the locking plate 511, thereby helping to fix or release the table support 100.

[0048] The second locking member 521 is linked to the locking plate 511, thus providing the advantage of more securely fixing the table support 100 in the unfolded state. That is, when the table support 100 is unfolded, the first locking member 510 fixes the angle of the tabletop 200, and the locking latch 521a of the second locking member 521 engages with the locking portion 121 of the table support 100, thereby providing additional fixation. This achieves a double-fixation structure, allowing the user to use the tabletop 200 stably.

[0049] In some embodiments, the locking module 500 further includes a housing 540, which forms the external shape of the locking module 500 and is fixedly mounted in the base 300. The housing 540 serves to protect and support components disposed within the locking module 500. The housing 540 is attached to the base 300 in a non-moving manner by bolts B.

[0050] The locking connector 530 is slidably engaged within the housing 540 via a second elastic member 522. The second elastic member 522 is engaged with a protrusion formed at the upper end 530a of the locking connector 530. The second elastic member 522 absorbs impacts, allowing the locking connector 530 to move flexibly within the housing 540 by a certain amount. Furthermore, the second elastic member 522 provides force, enabling the locking connector 530 to return to its accurate position. Thus, each time the user unfolds or folds the tabletop 200, the locking connector 530 can slide stably up and down, and when the tabletop 200 is fixed or released, it can return to its accurate position.

[0051] In other words, the second elastic member 522 can protect the locking connector 530 by absorbing the pressure applied to the locking connector 530 by the rotation of the table support 100 and the support connector 150, and when the table support 100 rotates back in the folding direction, the second spring member 522 provides elasticity so that the locking connector 530 returns to the initial position.

[0052] When the table support 100 rotates in the unfolded direction, the locking connector 530 is pressed downward by the second end of the support connector 150, thereby compressing the second elastic member 522 between the housing 540 and the locking connector 530. During this process, the first elastic member 512 remains in the extended state. For example, the second elastic member 522 can include a spring.

[0053] An external force can be applied to the angle adjustment module 600 to adjust the angle of the table support 100. That is, when an external force is applied to the guide 610 of the angle adjustment module 600 and the guide 610 causes the second locking member 521 to move upward, since the locking plate 511 is connected to the second locking member 521, the locking plate 511 moves upward while the first elastic member 512 contracts, and the locking plate 511 separates from the support fixing body 310, thereby enabling the base 300 and the table support 100 to rotate in a third direction.

[0054] Although this disclosure has been described with reference to specific embodiments shown in the accompanying drawings, it will be apparent to those skilled in the art that this disclosure can be changed and modified in various ways without departing from its scope.
