Technical Field

[0002] The structure of traditional portable folding tables is mostly made of components with sufficient materials, such as legs or bottom support seats. Although this can make the folding table itself more stable, it also makes it heavier and reduces its portability. At the same time, due to different manufacturers, the components of folding tables with different designs are non-standard and not universal. It is often difficult to find corresponding standard parts directly on the market, which makes it troublesome for users to repair. Once the product is damaged, it is easy to lead to a high product scrap rate, poor sustainability, and serious waste of resources, which in turn affects or damages the environment, which is not in line with the concept of sustainable design.

[0070] In the portable mode, the cantilever mechanism 3, the working panel 2 and the base 1 can be folded into a substantially rectangular parallelepiped structure to reduce the volume for easy carrying by users.
[0071] For details, please refer to Figure 1 and Figure 3 The cantilever mechanism 3 includes a vertical support component 31, an inclined support component 32, a connecting component 33 and a cantilever support component 34.

In the portable mode, the vertical support component 31 can be rotated to a state parallel to the base 1.
[0072] In the cantilever mode, the lower part of the oblique support assembly 32 is disposed in the base 1 , and the lower part of the oblique support assembly 32 can abut against the work surface on which the portable table is placed. The upper end of the oblique support assembly 32 is rotatably connected to the upper end of the vertical support assembly 31 .
[0073] The connecting assembly 33 is rotatably and slidably matched with the upper portion of the diagonal support assembly 32 , and the connecting assembly 33 can rotate in a transverse vertical plane. In the cantilever mode, the connecting assembly 33 is perpendicular to the upper portion of the diagonal support assembly 32 .
[0074] One end of the cantilever support assembly 34 is rotatably connected to one end of the connecting assembly 33 away from the inclined support assembly 32, and one end of the cantilever support assembly 34 away from the connecting assembly 33 is connected to the bottom surface of the working panel 2 to bear the bearing force of the working panel 2.
[0075] For further information, please refer to Figure 1 and Figure 3 The base 1 includes at least one bottom frame 11. In the present embodiment, the bottom frame 11 is provided with one. Specifically, the bottom frame 11 includes two first base rods 111 and two second base rods 112. The two first base rods 111 are arranged in parallel and opposite to each other, and the two second base rods 112 are arranged in parallel and opposite to each other.

Of course, in other embodiments, the bottom frame 11 can also be provided with two, three or other numbers.
[0076] For further information, please refer to Figure 1 and Figure 3 In this embodiment, the first connecting member 18 includes two matching half shells 181, and the half shells 181 are provided with grooves for connecting the rods of adjacent components. The two half shells 181 can be fixedly connected to each other by bolts, thereby realizing a detachable connection between adjacent components.
[0077] For further information, please refer to Figure 1 and Figure 3 The vertical support assembly 31 includes two vertical support parts 311, which are arranged in parallel and opposite to each other, and one end of the two vertical support parts 311 is rotatably connected to one end of the two first base rods 111 respectively, and the two vertical support parts 311 can be rotated to the top surface of the first base rod 111 and maintain a vertical state, and the other ends of the two vertical support parts 311 are rotatably connected to the upper part of the oblique support assembly 32.
[0078] For details, please continue to refer to Figure 1 and Figure 3The vertical support component 311 includes a first vertical support rod 311A, a second vertical support rod 311B and a third vertical support rod 311C. One end of the first vertical support rod 311A is rotatably connected to one end of the first base rod 111, and the first vertical support rod 311A can be rotated to the top surface of the first base rod 111. In this embodiment, in order to improve the aesthetics of the portable table when it is in the portable mode and to further protect the remaining components, a bending section is provided on the lower end of the first vertical support rod 311A, so that the bending section can contain more components between the two first vertical support rods 311A.
[0079] The lower end of the second vertical support rod 311B is also hinged to the upper end of the first vertical support rod 311A through the second connecting member 7. When in the cantilever mode, the second vertical support rod 311B is in line with the first vertical support rod 311A; when in the portable mode, the second vertical support rod 311B can be rotated to a state where its peripheral side surface is in contact with the first vertical support rod 311A.

In this embodiment, in order to achieve the standardization and modularization of the parts of the support block 321, the support block 321 is set as a frame structure composed of four rods, and the adjacent rods are fixedly connected to each other by the first connecting member 18.
[0083] The two first oblique support members 322 are arranged in parallel, and the lower ends of the two first oblique support members 322 are rotatably connected to the support blocks 321 respectively. When in the cantilever mode, the first oblique support members 322 are inclined, and the angle between the first oblique support members 322 and the transverse direction is an acute angle.

A hinge shaft 4 is provided on the top surface of the support block 321, and the lower end of the lower oblique support rod 322A is hinged to one end of the hinge shaft 4. In this embodiment, the two mutually parallel rod bodies of the support block 321 are sleeved with a first connecting member 18, and the two first connecting members 18 are connected by a fixed rod. The hinge shaft 4 is provided on the two first connecting members 18, and both ends of the hinge shaft 4 are respectively hinged to the lower ends of the two lower oblique support rods 322A through the first connecting member 18. The lower end of the upper oblique support rod 322B is rotatably connected to the upper end of the lower oblique support rod 322A, and the upper end of the upper oblique support rod 322B is rotatably connected to one end of the second oblique support component 323.

At this time, the upper inclined support rod 322B and the lower inclined support rod 322A are at the maximum rotation angle, so that the upper inclined support rod 322B and the lower inclined support rod 322A can maintain a collinear state under the action of the bearing force of the working panel 2, thereby making the first inclined support component 322 in a stable state.
[0085] One end of the two second oblique support components 323 is respectively hinged to the upper ends of the two upper oblique support rods 322B. In the present embodiment, the second oblique support component 323 includes a second oblique support rod 323A rotatably connected to the upper oblique support rod 322B, and the second oblique support rod 323A is hinged to the upper end of the upper oblique support rod 322B through a second connecting member 7, and a limiting portion is provided on the second connecting member 7 for limiting the maximum rotation angle of the second oblique support rod 323A. When in cantilever mode, the second oblique support rod 323A rotates to a state perpendicular to the upper oblique support rod 322B, and at this time, the second oblique support rod 323A and the upper oblique support rod 322B are at the maximum rotation angle, and the upper oblique support rod 322B and the second oblique support rod 323A can maintain a perpendicular state under the bearing force of the working panel 2, thereby making the first oblique support component 322 in a stable state, thereby, the bearing force of the working panel 2 can be transmitted to the support block 321 through the second oblique support rod 323A, the upper oblique support rod 322B and the lower oblique support rod 322A, and then transmitted to the work surface through the support block 321, thereby playing a role in sharing the force of the vertical support assembly 31, making the force of the portable table more reasonable and the cantilever mode more stable. When in portable mode, the peripheral side surface of the second oblique support rod 323A can be rotated to fit with the peripheral side surface of the first oblique support component 322.
[0086] For details, please refer to Figure 1 , Figure 3 and Figure 6 The connection assembly 33 includes two first connection rods 331, and the two first connection rods 331 are provided with a first slide groove 332 extending along the length direction of the first connection rod 331, and one end of the first connection rod 331 is rotatably connected with the end of the second oblique support rod 323A away from the upper oblique support rod 322B, and the rotation connection point between the second oblique support rod 323A and the first connection rod 331 can be slidably matched with the first connection rod 331 through the first slide groove 332, and the end of the first connection rod 331 away from the second oblique support rod 323A is rotatably connected with the cantilever support assembly 34. In this embodiment, the first connection rod 331 is rotatably and slidably matched with the second oblique support rod 323A through a second connection member 7, and the second connection member 7 is provided with a limiter for limiting the maximum rotation angle of the first connection rod 331. When in the cantilever mode, the limiter makes the first connection rod 331 at the maximum rotation angle, and at this time, the first connection rod 331 and the second oblique support rod 323A remain perpendicular to each other. Therefore, when the portable table is folded, the first connecting rod 331 can be slid to make the structure between the first connecting rod 331 and the second oblique support rod 323A more compact, further compressing the volume of the portable table in the portable mode, making it easier for users to carry and improving the practicality of the portable table.
[0087] For details, please refer to Figure 1 and Figure 7 The cantilever support assembly 34 includes a support frame 341 and a telescopic component 342. One end of the support frame 341 close to the connection assembly 33 is rotatably connected to the two first connecting rods 331.

The two longitudinal bars 341B are parallel and oppositely arranged. The two longitudinal bars 341B are arranged in the longitudinal direction, and one of the longitudinal bars 341B is used to connect the ends of the two cross bars 341A away from the first connecting rod 331, and the other longitudinal bar 341B is used to connect the side of the two cross bars 341A close to the first connecting rod 331. One end of 341A close to the first connecting rod 331 is hinged to the first connecting rod 331 through a second connecting member 7. The second connecting member 7 is provided with a limiting portion for limiting the maximum rotation angle of the cross bar 341A. When in the cantilever mode, the limiting portion makes the support frame 341 located at the maximum rotation angle, and at this time the support frame 341 remains in a horizontal state. Therefore, the setting of the second connecting member 7 between the cross bar 341A and the first connecting rod 331 can make the working panel 2 in a horizontal state, so as to improve the structural stability of the portable table when it is in the cantilever mode.
[0088] For further information, see Figure 7 and Figure 8 The telescopic component 342 is used to adjust the horizontal distance between the working panel 2 and the base 1. One end of the telescopic component 342 is connected to the support frame 341, and the other end of the telescopic component 342 is connected to the working panel 2 through a steering assembly 16. In this embodiment, the telescopic component 342 is composed of two telescopic rod structures 15 arranged parallel to each other, and one end of the telescopic rod structure 15 is detachably mounted on the longitudinal rod 341B of the support frame 341 near the first connecting rod 331, and the other end of the telescopic rod structure 15 passes through another longitudinal rod 341B and extends to the side of the longitudinal rod 341B away from the first connecting rod 331, and the ends of the two telescopic rod structures 15 away from the support frame 341 are connected to the working panel 2 through a rotating assembly, and the working panel 2 can be adjusted at multiple angles through the steering assembly 16. Therefore, the user can adjust the horizontal distance between the working panel 2 and the base 1 through the telescopic component 342.
[0089] Preferably, see Figure 1 , Figure 7 and Fig. 9, the steering assembly 16 includes a first rotating block 161, a second rotating block 162 and a third rotating block 163; the first rotating block 161 is rotatably connected to the two telescopic rod structures 15 on the support frame 341 and one end away from the connecting assembly 33, and the rotation direction of the first rotating block 161 is consistent with the rotation direction of the support frame 341; the second rotating block 162 is fixedly arranged on the top surface of the first rotating block 161. In this embodiment, the second rotating block 162 is a stepped shaft structure, and the axis of the second rotating block 162 is perpendicular to the top surface of the first rotating block 161. Of course, in other embodiments, the second rotating block 162 can also be detachably fixed to the first rotating block 161 in the form of a countersunk bolt. ; The third rotating block 163 is rotatably connected to the second rotating block 162, and the rotation axis of the third rotating block 163 is colinear with the axis of the second rotating block 162; the working panel 2 is rotatably connected to the third rotating block 163, and the rotation axis of the working panel 2 is perpendicular to the axis of the second rotating block 162. Therefore, the working panel 2 is connected to the supporting frame 341 by the steering assembly 16, and the working panel 2 can obtain three degrees of freedom of rotation. The user can adjust the tilt angle of the working panel 2 at will, which enhances the adaptability and practicality of the portable table. At the same time, a locking bolt with a knob is provided at the hinge between the first rotating block 161 and the two cross bars 341A, so that the user can tighten and fix the tilt angle of the first rotating block 161. In addition, in this embodiment, in order to facilitate the installation of the third rotating block 163, the third rotating block 163 is provided as two mutually matching half blocks, and the two half blocks are provided with matching parts that can be rotatably matched with the second rotating block 162, and the two half blocks can be detachably connected to each other by bolts, thereby forming a third rotating block 163 rotatably connected to the second rotating block 162.

The reinforcement component 5 includes at least one reinforcement rod 52, two first fixing plates 51 and a connecting shaft 53. In the present embodiment, two reinforcement rods 52 are provided.
[0091] The two first fixing plates 51 are respectively fixedly arranged on the two second oblique support rods 323A, and the two first fixing plates 51 are arranged oppositely and in parallel; the two reinforcing rods 52 are arranged between the two cross bars 341A, and the two reinforcing rods 52 are respectively rotatably connected to the rod bodies of the two cross bars 341A near the first connecting rod 331, and at the same time, the reinforcing rods 52 are provided with second slide grooves 521 extending along the length direction of the reinforcing rods 52; the connecting shaft 53 is passed through the second slide grooves 521 on the two reinforcing rods 52 and is used to connect the two first fixing plates 51, so that the connecting shaft 53 can rotate and slide with the reinforcing rods 52 through the second slide grooves 521. Therefore, in the cantilever mode, the load-bearing force of the working panel 2 can be transmitted to the second oblique support component 323 through the cantilever support assembly 34 and the reinforcing rod 52, and then transmitted to the work surface through the first oblique support component 322, thereby playing a role in sharing the load-bearing force of the cantilever support assembly 34, which is conducive to enhancing the structural stability of the cantilever mode of the portable table.
[0092] Preferably, see Figure 1 and Figure 3 The first oblique support member 322 is detachably provided with a counterweight assembly 6, which includes a counterweight block 61 and a counterweight member 62. The counterweight member 62 is provided with a counterweight cavity 8 for accommodating the counterweight block 61, and the counterweight block 61 can be placed in the counterweight cavity 8. In this embodiment, the interior of the counterweight block 61 adopts a honeycomb structure.
[0093] For the preferred option, please continue to read Figure 1 and Figure 3 The counterweight component 62 is also provided with a receiving cavity 9, which can be used to place items such as a laptop computer, so that the portable table has the function of carrying laptop computers and other sundries, further improving the practicality of the portable table. In addition, the counterweight component 62 can also be further optimized, and a sealing door structure is provided at the opening of the receiving cavity 9 of the counterweight component 62 to prevent items from falling out of the receiving cavity 9.
[0094] For the preferred option, please continue to read Figure 1 , Figure 3 and Fig.10 A second connecting rod and a third connecting rod 10 are connected between the two upper inclined support rods 322B, and the counterweight component 62 is composed of a counterweight box 621 and a counterweight plate 622.
[0095] A hook portion 12 is provided on one side surface of the counterweight box 621, and the cross-sectional shape of the hook portion 12 is in a “┌” shape, so the counterweight box 621 can be detachably engaged with the second connecting rod and the third connecting rod 10 through the hook portion 12. The receiving chamber 9 is provided on the counterweight box 621, and a first slider is fixedly provided at the bottom of the counterweight box 621. In this embodiment, there are two first sliders, and the first slider can be a T-shaped block or a dovetail block; a third slide groove 13 matching the first slider is provided on the top surface of the counterweight plate 622, and the two ends of the third slide groove 13 respectively penetrate the two side surfaces of the counterweight plate 622, and the first slider can slide and cooperate with the counterweight plate 622 through the third slide groove 13, so that the counterweight plate 622 can be detachably installed on the bottom surface of the counterweight box 621. At the same time, a fourth slide groove 14 is also provided on the side of the counterweight plate 622, and the extension direction of the fourth slide groove 14 is perpendicular to the extension direction of the third slide groove 13, and the upper end of the fourth slide groove 14 passes through the top surface of the counterweight plate 622, and the second slider 19 is fixedly connected to the connecting piece between the first oblique support rod and the second oblique support rod 323A, and the second slider 19 can slide and cooperate with the counterweight plate 622 through the fourth slide groove 14. In this embodiment, the second slider 19 can be a T-block or a dovetail block, so the counterweight plate 622 can be detachably installed on the first oblique support component 322 through the sliding cooperation between the second slider 19 and the fourth slide groove 14. Therefore, when the cantilever mode is used, the counterweight block 61, the counterweight box 621 and the counterweight plate 622 can enhance the overall strength of the portable table, optimize the force condition of the portable table, and reduce the risk of the portable table overturning due to excessive load of the working panel 2 in the cantilever mode.
[0096] For further information, see Figure 1 and Figure 8In order to make the height of the working panel 2 adjustable and improve the practicality of the portable table, the second vertical support rod 311B and the upper oblique support rod 322B are both set as a telescopic rod structure 15. The telescopic rod structure 15 includes a tube A151, a tube B152, a fixing sleeve 153 and a tightening sleeve 154, wherein the tube A151 and the tube B152 serve as the main body of the telescopic rod structure 15, and the ends of the tube A151 and the tube B152 that are far away from each other can be hinged or fixedly connected to the relevant components of the portable table. The fixing sleeve 153 can be fixed on the tube A151. The fixing sleeve 153 is provided with an external thread. The fixing sleeve 153 is provided with a plurality of notches extending along the length direction of the tube A151 and penetrating the end face of the fixing sleeve 153 away from the tube A151. Therefore, the plurality of notches divide the end of the fixing sleeve 153 into a plurality of clamping parts that can produce radial deformation. At the same time, the outer peripheral side surface of the clamping part away from the tube A151 is also subjected to a drafting process to form a certain taper. The tube B152 can be inserted into the tube A151 and the fixing sleeve 153. The tightening sleeve 154 is threadedly sleeved on the fixing sleeve 153, and a tapered part matching the drafting angle of the clamping part is provided on the inner side wall of the tightening sleeve 154. Therefore, the length of the telescopic rod structure 15 can be adjusted by screwing the tightening sleeve 154 and moving the tube A151 or the tube B152. Therefore, in the cantilever mode, the height of the working panel 2 can be adjusted by adjusting the length of the second vertical support rod 311B and the upper inclined support rod 322B.
[0097] For further information, see Figure 4 and Fig.10 The structure of the portable table is also arranged in a lifting table mode and a table and stool mode, wherein, in the lifting table mode, the first oblique support component 322 is in a vertical state, the second oblique support rod 323A is in a horizontal state, the support block 321 is arranged on one side of the bottom frame 11, the connecting component 33, the cantilever support component 34, the reinforcement component 5, the steering component 16 and the working panel 2 are all rotated to the top of the second oblique support rod 323A and kept in a horizontal state, and the counterweight component 62 can be hung on the second connecting rod and the third connecting rod 10, and the use of the counterweight block 61 is cancelled. Therefore, when the user goes out, there is no need to carry the counterweight block 61, which can reduce the overall weight of the portable table and facilitate the user to carry. At the same time, when the user uses the lifting table mode, the user can adjust the overall height of the portable table by adjusting the length of the second vertical support rod 311B and the upper oblique support rod 322B to meet the use needs of different users.
[0098] The table and stool mode cancels the use of the counterweight component 62 on the basis of the lifting table mode, and opens a fifth slide 17 on the side of the counterweight plate 622. The extension direction of the fifth slide 17 is the same as the extension direction of the fourth slide 14, and one end of the fifth slide 17 is connected to the third slide 13. Therefore, when using the table and stool mode, the user can place the counterweight box 621 on the ground, and make the openings of the receiving cavity 9 and the counterweight cavity 8 face the ground, and then set the fifth slide 17 on the counterweight plate 622 on the first slider, and then install the counterweight plate 622 on the counterweight box 621, so as to form a stool for the user to use. At the same time, the user can adjust the overall height of the portable table by adjusting the length of the second vertical support rod 311B and the upper oblique support rod 322B to adapt it to the user's sitting posture.
[0099] Preferably, see Figure 1 and Figure 3 The working panel 2 also includes a large plate 21 and a small plate 22. The bottom surfaces of the large plate 21 and the small plate 22 are both detachably mounted with fixing ears (not shown in the figure) by bolts, and the two fixing ears are provided with U-shaped parts (not shown in the figure), and a straight rod (not shown in the figure) can be inserted and clamped in the U-shaped parts. Therefore, the large plate 21 and the small plate 22 can be connected by inserting the two ends of the straight rod into the two U-shaped parts respectively. At this time, the large plate 21 can be used as a table for placing a laptop computer, and the small plate 22 can be used as a mouse board. When the mouse is not needed or there are not many items, the small plate 22 can also be removed. The user can decide whether to use the small plate 22 according to specific actual needs, which is conducive to improving the practicality of the portable table.
[0100] In addition, the components of the portable table of the embodiment of the present application are mostly common parts on the market, which reduces the use of non-standard parts, can reduce the number of mold openings in production, reduce production costs, and is conducive to standardized assembly production, and also convenient for subsequent users to repair or replace parts of the portable table. At the same time, since most of the components are common parts, and the structure and connection relationship of the parts are relatively simple, the portable table has a "DIY" attribute, which can be used for parent-child education and has certain educational significance.

[0104] Step 3, remove the counterweight assembly 6, and rotate the lower oblique support rod 322A upward to a state where it fits with the peripheral side of the upper oblique support rod 322B. At this time, the support block 321 and the lower oblique support rod 322A remain parallel and fit;
[0105] Step 4: Rotate the upper oblique support rod 322B upward to rotate the lower oblique support rod 322A to a state parallel to and in contact with the second oblique support rod 323A, and at the same time rotate the first connecting rod 331 upward to rotate the support frame 341 to a state parallel to and in contact with the upper oblique support rod 322B;
[0106] Step 5: Push the first connecting rod 331 to move the support frame 341 toward the upper inclined support rod 322B, making the structure more compact;
[0107] Step 6: Rotate the second vertical support rod 311B downward, and allow the working panel 2 to pass through the gap between the two first vertical support rods 311A, and rotate the working panel 2 to a vertical state, at which time the second vertical support rod 311B is parallel to and in contact with the first vertical support rod 311A;
[0108] Step 7: Place the counterweight assembly 6 on the lower rod of the first vertical support rod 311A, and rotate the bottom frame 11 so that the bottom frame 11 is close to the side of the counterweight assembly 6 away from the working panel 2, so as to form a Figure 2 The portable state of the roughly rectangular shape shown.
