Description

Technical Field

[0001] This invention relates to the field of folding table technology, and specifically to a folding table with multi-angle tilting function. Background Technology

[0002] Folding tabletops are widely used in offices, homes, and transportation (cars, high-speed trains, airplanes) due to their small footprint and flexible use. With the increasing prevalence of electronic devices, users' demand for using laptops, tablets, mobile phones, and other devices on tabletops is growing, making the need for adjustable tabletop tilt angles increasingly prominent.

[0003] Existing folding tabletops rely solely on a few spaced slots under the tabletop and a support rod for angle adjustment. The number of slots is limited, typically only 3 to 5 positions, which is insufficient to meet users' precise angle requirements. Adjustment is generally cumbersome; some designs require users to manipulate spring pins from under the tabletop or operate with both hands simultaneously. This makes adjustment difficult when the tabletop is loaded with items, severely impacting the user experience. Furthermore, the locking mechanism is unreliable; relying solely on the slots and support rod cannot guarantee tabletop stability when tilted, especially when carrying heavy items, leading to tabletop wobbling or even locking failure. Summary of the Invention

[0004] The purpose of this invention is to provide a folding table with multi-angle tilting function to solve the problems of limited folding table positions, cumbersome operation, unstable locking, and difficulty in meeting the needs of fine adjustment in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding tabletop with multi-angle tilting function, comprising a fixed base, two side plates symmetrically fixedly connected to the fixed base, a protrusion fixedly connected to the fixed base, a tabletop body disposed on the protrusion, support rods symmetrically disposed on both sides of the tabletop body, universal joints disposed at both ends of the two support rods, the two universal joints being respectively disposed on one side and the side plate of the corresponding tabletop body, and a tilt adjustment component disposed between the protrusion and the tabletop body;

[0006] The pitch adjustment assembly includes a connecting seat disposed on the protrusion, two support plates symmetrically fixedly connected to the connecting seat, a pivot on the table body, the table body being rotatably connected between the two support plates via the pivot, an arc-shaped groove being formed on each of the two support plates, and symmetrical sliding grooves being formed on the table body, with a locking shaft disposed between the two sliding grooves. The pitch adjustment assembly also includes a locking component, which is used to lock the locking shaft at a corresponding angle position.

[0007] A horizontal deflection adjustment component is provided between the bump and the connector, and the horizontal deflection adjustment component is used to adjust the horizontal deflection angle of the connector relative to the bump.

[0008] Furthermore, both support rods are inclinedly arranged on both sides of the tabletop body, and the universal joints at both ends of each support rod are respectively connected to the side wall of the tabletop body and the inner wall of the corresponding side plate.

[0009] Furthermore, both ends of the card shaft pass through the corresponding sliding grooves and extend into the corresponding arc-shaped grooves, and the card shaft slides along the sliding grooves and moves in the arc-shaped grooves.

[0010] Furthermore, the locking component includes multiple slots that are respectively opened on the two receiving plates and are evenly distributed along the side arc of the receiving plates. The two ends of the locking shaft are respectively engaged in the two corresponding slots, and the slots are connected to the arc-shaped groove.

[0011] Furthermore, the locking component also includes an L-shaped pull plate disposed within the tabletop body. The tabletop body has a slot at its bottom. One end of the L-shaped pull plate is fixedly connected to the locking shaft, and the other end of the L-shaped pull plate extends out of the tabletop body and is slidably connected within the slot.

[0012] Furthermore, the locking component also includes a plurality of elastic elements disposed within the tabletop body. The plurality of elastic elements are evenly distributed along the length direction of the tabletop body, and the two ends of each elastic element are respectively connected to the L-shaped pull plate and the tabletop body.

[0013] Furthermore, the horizontal deflection adjustment assembly includes two fixed plates symmetrically fixedly connected to the upper and lower ends of the protrusion. A first ratchet ring is fixedly connected to the inner side of each of the two fixed plates. A connecting shaft is provided inside the two fixed plates and the two first ratchet rings. A sleeve is fixedly connected to the connecting seat. A second ratchet ring is fixedly connected to both ends of the sleeve. The sleeve and the two second ratchet rings are all sleeved on the connected shaft.

[0014] Furthermore, the horizontal deflection adjustment assembly also includes a knob rotatably connected to the top of the connecting shaft, the side of which abuts against the top surface of the fixed plate located above.

[0015] Furthermore, the first and second ratchet rings mesh with each other, the connecting shaft and the knob are connected by an eccentric shaft, and the connecting shaft moves up and down relative to the two fixed plates by rotating the knob.

[0016] Furthermore, the two first ratchet rings are respectively arranged in a one-to-one correspondence with the two second ratchet rings, the sleeve is located between the two second ratchet rings, and the connecting shaft passes through the upper fixing plate, the two first ratchet rings, the sleeve and the two second ratchet rings in sequence, with the lower end of the connecting shaft set on the lower fixing plate.

[0017] Compared with existing technologies, this invention provides a folding tabletop with multi-angle tilting function. Through the sliding cooperation of the arc-shaped groove and the locking shaft, and with multiple locking slots evenly distributed along the arc of the side of the supporting plate, a wide range of multi-level fine adjustment of the tabletop's tilt angle is achieved. The number of locking slots can be flexibly set according to actual needs, significantly improving the accuracy and applicability of angle adjustment. Users only need to pull the L-shaped pull plate with one hand to unlock. After adjustment, releasing the plate will cause the elastic element to automatically push the locking shaft into the corresponding locking slot to complete the locking. The entire operation does not require getting up or reaching under the tabletop, making it more convenient to use. Both ends of the locking shaft simultaneously engage with the corresponding locking slots on the two supporting plates. With the adaptive auxiliary support provided by the universal joints on both sides of the support rods, a double stability guarantee is formed, ensuring that the tabletop has reliable load-bearing capacity at any tilt angle. This effectively avoids shaking and locking failure problems. The overall structure is compact, and the components work together to achieve an integrated design of folding and adjustment functions.

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] Example 1:

[0031] This invention provides a folding tabletop with multi-angle tilting function, comprising a fixed base 1, two side plates 11 symmetrically fixedly connected to the fixed base 1, a protrusion 2 fixedly connected to the fixed base 1, a tabletop body 3 mounted on the protrusion 2, support rods symmetrically arranged on both sides of the tabletop body 3, and universal joints 41 at both ends of the two support rods 4 respectively mounted on one side of the corresponding tabletop body 3 and the side plate 11. A tilt adjustment assembly 5 is provided between the protrusion 2 and the tabletop body 3. The fixed base 1 serves as the mounting base for this device and is used to fix it to external supports such as chair backs, table frames, and walls, providing stable mounting support for this device. The side plates 11 are symmetrically fixedly connected to the fixed base 1. On both sides, the side plate 11 is used to install the universal joint 41 at the end of the support rod 4 and to provide support and limit on both sides of the table body 3. The protrusion 2 serves as a connecting base and is used to install the connecting seat 51 of the pitch adjustment component 5 and the horizontal deflection adjustment component 6. The table body 3 has a flat working surface for carrying items and is the desktop part directly used by the user. The support rod 4 is symmetrically arranged on both sides of the table body 3 and is inclined. The support rod 4 is used to provide auxiliary support force when the table body 3 is unfolded and used to enhance the load-bearing stability of the table body 3. The universal joint 41 is used to realize the universal rotation connection between the two ends of the support rod 4 and the table body 3 and the side plate 11, so that the support rod 4 can adaptively adjust the support direction as the angle of the table body 3 changes.

[0032] The pitch adjustment assembly 5 includes a connecting seat 51 mounted on the protrusion 2. Two support plates 52 are symmetrically fixedly connected to the connecting seat 51. A pivot 53 is provided on the tabletop body 3, and the tabletop body 3 is rotatably connected between the two support plates 52 via the pivot 53. Both support plates 52 are provided with arc-shaped grooves 54, and the tabletop body 3 is provided with symmetrical sliding grooves 55. A retaining shaft 56 is provided between the two sliding grooves 55. The pitch adjustment assembly 5 also includes a locking member 57, which is used to lock the retaining shaft 56 at a corresponding angle position. The connecting seat 51 serves as the mounting base of the pitch adjustment assembly 5, supporting the tabletop body 3 and connecting the tabletop body 3 to the protrusion 2. The support plates 52 are used to connect the tabletop body 3 to the protrusion 2 via the pivot 53. 3 is rotatably connected to the tabletop body 3, providing support for the pitch rotation of the tabletop body 3. The rotating shaft 53 serves as the rotation center for the pitch rotation of the tabletop body 3, enabling the tabletop body 3 to rotate relative to the receiving plate 52 around the rotating shaft 53. The arc groove 54 provides a moving guide path for the locking shaft 56, allowing the locking shaft 56 to slide along the arc groove 54 when the tabletop body 3 pitches. The sliding groove 55 provides sliding space for the locking shaft 56 on the tabletop body 3. The two ends of the locking shaft 56 pass through the corresponding sliding groove 55 and extend into the corresponding arc groove 54. The locking shaft 56 serves as a transmission and locking component for pitch adjustment. When the tabletop body 3 pitches, it slides along the arc groove 54 and locks itself in place after being engaged in the locking groove 571.

[0033] Both support rods 4 are inclinedly arranged on both sides of the table body 3. The universal joints 41 at both ends of each support rod 4 are connected to the side wall of the table body 3 and the inner wall of the corresponding side plate 11, respectively. The two ends of the locking shaft 56 pass through the corresponding sliding groove 55 and extend into the corresponding arc groove 54. The locking shaft 56 slides along the sliding groove 55 and moves in the arc groove 54.

[0034] The locking component 57 includes multiple slots 571 that are respectively opened on the two receiving plates 52 and are evenly distributed along the side arc of the receiving plate 52. The two ends of the locking shaft 56 are respectively engaged in the two corresponding slots 571. The slots 571 are connected to the arc groove 54. The two ends of the locking shaft 56 are respectively engaged in the two corresponding slots 571. The slots 571 are used to cooperate with the locking shaft 56 to realize the positioning and locking of the table body 3 at the corresponding pitch angle.

[0035] The locking component 57 also includes an L-shaped pull plate 572 disposed in the table body 3. The bottom of the table body 3 has a slot 573. One end of the L-shaped pull plate 572 is fixedly connected to the locking shaft 56. The other end of the L-shaped pull plate 572 extends out of the table body 3 and is slidably connected in the slot 573. The L-shaped pull plate 572 is used by the user to pull it to drive the locking shaft 56 out of the slot 571 to unlock. The slot 573 is used to provide sliding guidance and limit for the L-shaped pull plate 572, so that the extended end of the L-shaped pull plate 572 can slide in the slot 573.

[0036] The locking component 57 also includes a plurality of elastic elements 574 disposed within the tabletop body 3. The plurality of elastic elements 574 are evenly distributed along the length direction of the tabletop body 3. The two ends of each elastic element 574 are respectively connected to the L-shaped pull plate 572 and the tabletop body 3. The elastic elements 574 are compression springs. The elastic elements 574 are used to apply a pushing force to the L-shaped pull plate 572, so that the L-shaped pull plate 572 pushes the locking shaft 56 into the locking groove 571 when no external force is applied.

[0037] Working principle: In the normal folded state, the table body 3 is rotatably connected to the two support plates 52 of the connecting seat 51 via the pivot 53. At this time, under the pushing force of the elastic element 574, the two ends of the locking shaft 56 are respectively locked into the locking grooves 571 at the very end of the two support plates 52, and the two ends of the locking shaft 56 are located at the bottom of the two sliding grooves 55. When the user needs to open the folding table for use, he first pulls the L-shaped pull plate 572 to extend one end of the groove 573 at the bottom of the table body 3. During the pulling process, the L-shaped pull plate 572 overcomes the elastic force of the elastic element 574 and drives the locking shaft 56 to move along the sliding grooves 55 on the table body 3. When the two ends of the locking shaft 56 are completely removed from the locking grooves 571, the locking shaft 56 releases the locking of the table body 3, and the two ends of the locking shaft 56 enter the arc grooves 54. At this time, the table body 3 can rotate freely between the two support plates 52 with the pivot 53 as the fulcrum.

[0038] The user moves the free end of the tabletop body 3 up or down, causing the tabletop body 3 to rotate relative to the receiving plate 52 around the pivot 53. During the rotation of the tabletop body 3, the two ends of the locking shaft 56 slide in the arc grooves 54 on the two receiving plates 52 respectively. When the tabletop body 3 rotates to the tilt angle required by the user, the user releases the L-shaped pull plate 572. Under the pushing force of the elastic element 574, the L-shaped pull plate 572 drives the locking shaft 56 back to its original position along the slide groove 55. The two ends of the locking shaft 56 enter the two locking slots 571 corresponding to the angle position from the arc groove 54. The locking shaft 56 engages with the corresponding locking slots 571, completing the angle locking of the tabletop body 3 in the tilt direction.

[0039] Throughout the pitch angle adjustment process, the two support rods 4 adaptively adjust the support direction through the universal joint 41, always providing stable auxiliary support to the table body 3, ensuring that the table body 3 has reliable load-bearing stability at any pitch angle.

[0040] When the user needs to fold and store the tabletop body 3, first pull the L-shaped pull plate 572 to disengage the locking shaft 56 from the locking slot 571, rotate the tabletop body 3 to a vertical position, and attach it to the fixed base 1. Then release the L-shaped pull plate 572 to allow the locking shaft 56 to be inserted into the last locking slot 571, thus completing the folding and storage.

[0041] Example 2:

[0042] As attached Figure 6 To be continued Figure 7 As shown, this embodiment is basically the same as the previous embodiment, except that a horizontal deflection adjustment component 6 is provided between the protrusion 2 and the connecting seat 51. The horizontal deflection adjustment component 6 is used to adjust the horizontal deflection angle of the connecting seat 51 relative to the protrusion 2, thereby realizing the left and right deflection adjustment of the table body 3 in the horizontal direction.

[0043] The horizontal deflection adjustment assembly 6 includes two fixing plates 61 symmetrically fixedly connected to the upper and lower ends of the protrusion 2. A first ratchet ring 62 is fixedly connected to the inner side of each fixing plate 61. A connecting shaft 63 is provided inside the two fixing plates 61 and the two first ratchet rings 62. A sleeve 64 is fixedly connected to the connecting seat 51. Second ratchet rings 65 are fixedly connected to both ends of the sleeve 64. The sleeve 64 and the two second ratchet rings 65 are all sleeved on the connected shaft 63. The fixing plates 61 are used to install the first ratchet rings 62 and provide horizontal deflection adjustment. The first ratchet ring 62 is used to engage with the second ratchet ring 65 to lock the horizontal deflection angle. The connecting shaft 63 serves as the rotation center for adjusting the horizontal deflection. It is used to pass through the sleeve 64 and provide a rotation fulcrum for the horizontal deflection of the connecting seat 51. The sleeve 64 is used to rotatably connect the connecting seat 51 and the connecting shaft 63, so that the connecting seat 51 can deflect horizontally around the connecting shaft 63. The two first ratchet rings 62 are respectively set to correspond one-to-one with the two second ratchet rings 65. The sleeve 64 is located between the two second ratchet rings 65.

[0044] The horizontal deflection adjustment assembly 6 also includes a knob 66 ​​rotatably connected to the top of the connecting shaft 63. The side of the knob 66 ​​abuts against the top surface of the upper fixed plate 61. The knob 66 ​​is used by the user to rotate to drive the connecting shaft 63 to move up and down relative to the two fixed plates 61.

[0045] The first ratchet ring 62 and the second ratchet ring 65 are engaged. The connecting shaft 63 and the knob 66 ​​are connected by an eccentric shaft. The connecting shaft 63 moves up and down relative to the two fixed plates 61 by rotating the knob 66. The two first ratchet rings 62 are respectively set to correspond one-to-one with the two second ratchet rings 65. The sleeve 64 is located between the two second ratchet rings 65. The connecting shaft 63 passes through the upper fixed plate 61, the two first ratchet rings 62, the sleeve 64 and the two second ratchet rings 65 in sequence. The lower end of the connecting shaft 63 is set on the lower fixed plate 61.

[0046] Working principle: Under normal conditions, the two first ratchet rings 62 are engaged with the corresponding two second ratchet rings 65 respectively. The connecting seat 51 is sleeved on the connecting shaft 63 through the sleeve 64. Under the action of the ratchet ring engagement, the connecting seat 51 cannot be horizontally deflected relative to the protrusion 2, and the table body 3 remains in the current horizontal orientation.

[0047] When the user needs to adjust the horizontal left and right tilt angle of the table body 3, first turn the knob 66 ​​on the top of the connecting shaft 63. Since the connecting shaft 63 and the knob 66 ​​are connected by an eccentric shaft, when the knob 66 ​​is turned, the relative position between the eccentric cam surface of the knob 66 ​​and the top surface of the fixed plate 61 above changes. After the knob 66 ​​is turned, the knob 66 ​​cancels the lifting effect on the connecting shaft 63, and the two fixed plates 61 open slightly to the upper and lower sides respectively. The two first ratchet rings 62 move with the corresponding fixed plates 61, thereby disengaging from the two second ratchet rings 65 at both ends of the sleeve 64.

[0048] At this time, the connecting seat 51 is in a state where it can be freely deflected horizontally. The user can rotate the table body 3 to the left or right as needed. The connecting seat 51 deflects horizontally relative to the protrusion 2 through the sleeve 64 around the connecting shaft 63, thereby driving the entire table body 3 to rotate left and right in the horizontal direction, so as to realize the adjustment of the horizontal orientation.

[0049] Once the tabletop body 3 is adjusted to the required horizontal deflection angle, the user rotates the knob 66 ​​in the opposite direction. Under the action of the eccentric shaft connection, the knob 66 ​​presses the two fixing plates 61 through the connecting shaft 63. The two fixing plates 61 are pulled towards the middle respectively, and the two first ratchet rings 62 re-engage with the corresponding two second ratchet rings 65, thus locking the horizontal deflection angle. After this, the connecting seat 51 can no longer deflect horizontally relative to the protrusion 2, and the tabletop body 3 remains stably in the adjusted horizontal orientation.

[0050] The pitch adjustment component 5 and the horizontal deflection adjustment component 6 are independent yet work together. The horizontal deflection adjustment component 6 supports the entire pitch adjustment component 5 and the table body 3 through the connecting seat 51. Users can adjust the pitch angle or horizontal deflection angle of the table body 3 individually as needed, or adjust the angles in both dimensions simultaneously, so that the table body 3 can be flexibly adjusted in three-dimensional space to meet the diverse needs of different usage scenarios.

[0051] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
