Description

Technical Field

[0001] This utility model relates to the field of furniture and office equipment, specifically to a flip-up height-adjustable table. Background Technology

[0002] Modern medical research indicates that prolonged sitting can negatively impact health. For example, prolonged sitting leads to calorie intake exceeding calorie expenditure, causing fat accumulation and weight gain. Sedentary lifestyles slow blood circulation, resulting in insufficient blood supply to the brain and causing mental stress. Maintaining a sitting posture for extended periods puts the entire body weight on the base of the spine, and the lack of shoulder and neck movement can easily cause cervical stiffness, and in severe cases, even spinal deformities leading to kyphosis and bone spurs.

[0003] A height-adjustable desk is a type of desk that allows users to alternate between sitting and standing while working, primarily designed to improve the comfort of prolonged sitting. For example, a typical tilting desk includes a frame, a telescopic tube, and a tilting mechanism. The telescopic tube supports the frame via the tilting mechanism, and changes in the length of the telescopic tube adjust the height of the frame accordingly.

[0004] The telescopic tube needs to be used in conjunction with a gas spring, which allows for height adjustment and fixation of the telescopic tube. The flipping mechanism includes a positioning rod and a pull rod; the positioning rod and pull rod are hinged to the table frame respectively; the table frame can be placed horizontally or vertically relative to the positioning rod; the positioning rod has a first positioning groove and a second positioning groove; when the table frame is horizontal, the pull rod is connected to the first positioning groove; when the table frame is vertical, the pull rod is connected to the second positioning groove. To change the state of the tabletop, simply change the connection position of the pull rod.

[0005] While the aforementioned flip-up desk achieves both lifting and flipping of the desktop, this type of flip-up desk can only flip a single desktop. As user needs increase, for example, when multiple objects are placed on the desktop, and the user needs to keep some items in place while changing the position of others, the aforementioned single desktop can only change the position of the other items. Therefore, it is clear that the aforementioned flip-up desk cannot simultaneously meet multiple user needs. Utility Model Content

A part of the drive assembly is located in the receiving cavity. The drive assembly engages with one end of the clutch block. The drive assembly drives the clutch block to move radially along the end cover, causing the other end of the clutch block to engage or disengage from the end cover.

[0011] Furthermore, a first tooth is provided on the inner circumferential surface of the other end of the end cap, and a second tooth is provided on the circumferential surface of the other end of the clutch block. After the second tooth meshes with the first tooth, the clutch, support frame and connecting plate are fixed together as one unit.

[0012] Furthermore, the drive assembly includes a handle, a drive shaft, a cam, a drive disc, and an elastic component. The handle is fixed to the drive shaft. The housing has a shaft hole. One end of the drive shaft passes through the shaft hole in the housing and extends into the receiving cavity. The cam and the drive disc are respectively sleeved on the drive shaft and fixed to the drive shaft. There are multiple clutch blocks. These clutch blocks are located around the cam, and the circumferential surface of the cam engages with one end of the clutch block. The clutch block has a protrusion. The drive disc has a cam groove. The cam groove engages with the protrusion. The elastic component is sleeved on the drive shaft and is connected to the housing and the drive shaft respectively.

[0013] Furthermore, the support frame includes a main support component, a support arm, and a retaining ring. The main support component is fixed to the clutch, the support arm is fixed to the main support component, the second tabletop is fixed to the support arm, and the retaining ring is fixed to the main support component. The retaining ring is provided with a protrusion.

[0018] In use, this invention allows the first desktop to rise and fall via the lifting structure of the support assembly. The second desktop, connected to the support frame via a connecting plate, rises and falls along with the first desktop. Alternatively, the second desktop, fixed to the support assembly via the support frame, allows the support frame to rise and fall along with the support assembly. Since the clutch is engaged, the support frame is fixed to the connecting plate. Therefore, when the second desktop needs to be flipped or rotated relative to the first desktop, disengaging the clutch releases the clutch from locking the support frame and connecting plate. Applying torque to the second desktop causes the support frame to flip or rotate relative to the connecting plate.

[0019] In summary, users can raise and lower this utility model as needed, and rotate the second desktop as needed, thereby meeting users' needs for the desktop of the height-adjustable table to be in multiple states. Attached Figure Description

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figures 1 to 11As shown, the tilting and lifting table of this embodiment includes a support assembly A, a first desktop B, a connecting plate C, a support frame D, a clutch E that switches the support frame D and the connecting plate C between engaged and disengaged states, and a second desktop F. The following is a detailed description of each part and the relationship between them.

[0037] The first desktop B is fixed to the support component A. The support component A and the first desktop B cannot be flipped or rotated relative to each other. Therefore, the first desktop B is a fixed desktop relative to the second desktop F.

[0038] Support assembly A includes a base 1, an outer tube 2, an inner tube 3, a mounting assembly 4, a gas spring 5, and a control assembly for controlling the gas spring 5. The outer tube 2 is fixed to the base 1. A portion of the inner tube 3 is located inside the outer tube 2 and has a clearance fit with the outer tube 2. The end of the inner tube 3 located outside the outer tube 2 is fixed to the mounting assembly 4. The first desktop B and the connecting plate C are respectively fixed to the mounting assembly 4. The gas spring 5 passes through the inner tube 3. One end of the gas spring 5 is fixed to the base 1 or the outer tube 2, and the other end of the gas spring 5 is fixed to the mounting assembly 4. The control assembly is mounted on the mounting assembly 4 and cooperates with the gas spring 5. After the gas spring 5 is activated by the control assembly, if no pressure is applied to the first desktop B, the gas spring 5 will automatically rise, pushing the first desktop B upward. If pressure is applied to the first desktop B, the first desktop B and support assembly A will descend.

[0039] Mounting assembly 4 includes a mounting plate 4a. Two guide members 4b are spaced apart at one end of the mounting plate 4a, and an assembly groove 4c is provided between the two guide members 4b. The control assembly mates with the assembly groove 4c. Two opposing sidewalls of the mounting plate 4a are provided with L-shaped support members 4d. After the first desktop B mates with the support members 4d, screws are used to connect the first desktop B to the support members 4d, thus securing the first desktop B and the support members 4d together. The mounting plate 4a has a through hole 4e, through which a gas spring 5 mates with the control assembly.

[0040] The control assembly includes a wrench bracket 7, a stop lever 8, and a wrench 9. The wrench bracket 7 is fixed to the mounting assembly 4. The wrench bracket 7 has a groove 7a. The stop lever 8 engages with the groove 7a and is fixed to the wrench bracket 7. When the wrench 9 is operated, the stop lever 8 limits the height to which the wrench 9 rises. The wrench 9 passes through the groove 7a. One end of the wrench 9 engages with a gas spring 5. The wrench 9 is clearance-fitted with the mounting groove 4c. When an upward force is applied to the wrench 9, the guide component 4b guides the wrench 9.

[0041] The connecting plate C is fixed to the support assembly A, and the other end of the connecting plate C is fixed to the mounting plate 4a in the support assembly A. One end of the connecting plate C is at the same height as the upper end of the support component 4d, and the other end of the connecting plate C is located below the mounting assembly 4. Multiple limiting components C1 protruding from the circumference of the connecting plate C are arranged at intervals on its circumference. The connecting plate C includes a rectangular first mounting plate C2 and a second mounting plate C3 with an arc-shaped circumference. The first mounting plate C2 and the second mounting plate C3 are fixed, and the limiting components C1 are disposed on the arc-shaped circumference of the second mounting plate C3.

[0042] Clutch E is connected to connecting plate C. Clutch E includes housing 10, end cover 11, clutch block 12, and drive assembly. Housing 10 has a receiving cavity 10a. One end of end cover 11 is fixed to connecting plate C, and the other end of end cover 11 is located in receiving cavity 10a. End cover 11 is rotatably engaged with housing 10. Housing 10 has a retaining ring 10d, which axially limits end cover 11, thereby preventing end cover 11 from exiting receiving cavity 10a. Housing 10 has multiple guide blocks 10b, and a guide groove 10c is formed between two adjacent guide blocks 10b. Clutch block 12 is clearance engaged with guide groove 10c, thereby fixing clutch block 12 and housing 10 in the circumferential direction.

[0043] A portion of the drive assembly is located within the receiving cavity 10a. The drive assembly engages with one end of the clutch block 12, driving the clutch block 12 to move radially along the end cover 11, causing the other end of the clutch block 12 to engage or disengage from the end cover 11. The inner circumferential surface of the other end of the end cover 11 has a first tooth 11a, and the circumferential surface of the other end of the clutch block 12 has a second tooth 12a. Since the end cover 11 is fixed to the connecting plate C, when the second tooth 12a engages with the first tooth 11a, the clutch block 12 and the end cover 11 cannot rotate relative to each other. Since the clutch block 12 is installed inside the housing 10, when the clutch block 12 cannot rotate relative to the end cover 11, the housing 10 also cannot rotate relative to the end cover 11. Therefore, when the clutch E is engaged, the engagement of the clutch E fixes the support frame D and the connecting plate C together, at which point the support frame D cannot rotate relative to the connecting plate C.

[0044] The drive assembly includes a handle 13, a drive shaft 14, a cam 15, a drive disc 16, and an elastic component 17. The handle 13 is fixed to the drive shaft 14. The housing 10 has a shaft hole. One end of the drive shaft 14 passes through the shaft hole on the housing 10 and extends into the receiving cavity 10a. The cam 15 and the drive disc 16 are respectively sleeved on the drive shaft 14 and fixed to the drive shaft 14. The cam 15 is located between the drive disc 16 and the bottom wall of the receiving cavity 10a. There are multiple clutch blocks 12, which are located around the cam 15. The circumferential surface of the cam 15 engages with one end of the clutch block 12. When the drive shaft 14 is driven to rotate forward by the handle 13, the drive shaft 14 drives the cam 15 and the drive disc 16 to rotate forward. The cam 15 drives the clutch block 12 to move radially along the end cover 11, thereby causing the second tooth 12a on the clutch block 12 to feed towards the first tooth 11a on the end cover 11, and finally causing the second tooth 12a to mesh with the first tooth 11a. This puts the clutch E in the engaged state, thereby restricting the clutch block 12 from rotating circumferentially along the end cover 11.

[0045] The clutch block 12 is provided with a protrusion 12b, and the drive disk 16 is provided with a cam groove 16a. The cam groove 16a cooperates with the protrusion 12b. When the drive shaft 14 reverses, the drive shaft 14 drives the cam 15 and the drive disk 16 to reverse. The cam groove 16a on the drive disk 16 drives the clutch block 12 to move radially along the end cover 11, thereby separating the second tooth 12a on the clutch block 12 from the first tooth 11a on the end cover 11. This makes the clutch E in a disengaged state. Without the first tooth 11a restricting the circumferential movement of the clutch block 12, applying torque to the housing 10 can make the housing 10 rotate relative to the end cover 11.

[0046] The elastic component 17 is fitted onto the drive shaft 14 and is connected to both the housing 10 and the drive shaft 14. The elastic component 17 is a spiral spring or torsion spring. When the clutch E is engaged, it applies force to the handle 13, causing the drive shaft 14 to rotate forward. The drive shaft 14 drives the cam 15 and drive disc 16 to rotate forward, switching the clutch E from the engaged state to the disengaged state. At this time, the torque generated by the drive shaft 14 is transmitted to the elastic component 17, causing it to stretch and generate elastic potential energy. When the handle 13 is released, the elastic component 17 automatically resets. The accumulated elastic potential energy in the elastic component 17 drives the drive shaft 14 to rotate in the reverse direction, causing the cam 15 and drive disc 16 to rotate in the reverse direction, switching the clutch E from the disengaged state to the engaged state.

[0047] Support frame D is connected to clutch E, and second desktop F is fixed to support frame D. Support frame D includes main support component 18, support arm 19, and retaining ring 20. Main support component 18 is fixed to clutch E, support arm 19 is fixed to main support component 18, second desktop F is fixed to support arm 19, and retaining ring 20 is fixed to main support component 18. Retaining ring 20 is provided with protrusion 20a. Multiple limiting components C1 protruding from the circumference of connecting plate C are arranged at intervals on the circumference of connecting plate C. Protrusion 20a is located between two adjacent limiting components C1. When clutch E applies torque to second desktop F in the disengaged state, second desktop F drives main support component 18 to rotate, and retaining ring 20 rotates with main support component 18. When protrusion 20a abuts against limiting component C1, limiting component C1 limits protrusion 20a, preventing further rotation of main support component 18.

[0048] The main support component 18 is a tubular component with an opening 18a. A portion of the clutch E passes through this opening 18a and is exposed to the air. This prevents most of the parts in the clutch E from being exposed to the air. The main support component 18 protects the clutch E on the one hand and improves the aesthetics of the product on the other.

[0049] The second desktop F is equipped with a baffle F1. When the second desktop F is rotated, it is tilted relative to the first desktop B. The baffle F1 can support the items. The cross-section of the baffle F1 is L-shaped. The baffle F1 is fixed to the second desktop F with screws.

[0050] Example 2

[0051] like Figure 12 and Figure 13 The difference between this embodiment and embodiment one is as follows: one end of the support frame D is fixed to the support component A, the clutch E is fixed to the support frame D, the connecting plate C is fixed to the clutch E, and the connecting plate C is fixed to the second desktop F.

[0052] The support frame D includes a main support component 18 and a support arm 19. The main support component 18 is a hollow tube, and one end of the main support component 18 is fixed to the support assembly A. The main support component 18 passes through the support arm 19 and is clearance-fitted with the support arm 19. The support arm 19 is fixed to the second desktop F. One end of the end cap 11 in the clutch E is fixed to the other end of the main support component 18, and the connecting plate C is fixed to the housing 10.

[0053] When torque is applied to the drive shaft 14 via the handle 13, the clutch is disengaged, thereby releasing the clutch E from locking the support frame D and the connecting plate C. When torque is applied to the second tabletop F, the second tabletop F transmits the torque to the connecting plate C and the support arm 19. The connecting plate C drives the housing 10 to rotate relative to the end cover 11, and the support arm 19 to rotate relative to the main support component 18.

[0054] In this embodiment, an arc-shaped groove 18b is provided on the main support component 18, and a protruding tooth 19a is provided on the support arm 19. The protruding tooth 19a cooperates with the arc-shaped groove 18b. When the support arm 19 rotates forward relative to the main support component 18, the protruding tooth 19a and one end of the arc-shaped groove 18b form an abutment, thus preventing the support arm 19 from continuing to rotate forward relative to the main support component 18. When the support arm 19 rotates backward relative to the main support component 18, the protruding tooth 19a and the other end of the arc-shaped groove 18b form an abutment, thus preventing the support arm 19 from continuing to rotate backward relative to the main support component 18. That is, through the cooperation of the protruding tooth 19a and the arc-shaped groove 18b, the angle of forward or reverse rotation of the second desktop F can be limited.
