Description

Technical Field

[0001] This invention relates to the field of office and home furnishing products, and more particularly to a flip-up table. Background Technology

[0002] Office desks are a common household item. In order to be able to be stored away when not in use, more and more office desks are now designed with flip-top tabletops. Patent publication document CN203399802U discloses an office desk with a flip-top tabletop. However, there is a problem in the actual use of this type of office desk. When the tabletop is in a horizontal state (i.e., when the locking groove and the locking piece are engaged), the entire tabletop is in a fixed state. When the locking groove and the locking piece are not engaged (i.e., when the tabletop is in a vertical state), the tabletop is in a state of free wobbling. The tabletop being able to wobble will inevitably lead to damage to the tabletop. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a flip-top table.

[0004] The technical solution adopted in this invention is as follows:

[0005] A flip-up table includes two legs, a crossbeam, and a support. Each leg has a support. The two ends of the crossbeam engage with the supports on the two legs. The table also includes a slide plate, a pull rod, a spring, and a handle. The support has a first engaging block and a second engaging block. The first engaging block has a pin, and the slide plate is rotatably mounted on the pin. The pull rod is elastically mounted on the slide plate via a spring. The handle engages with the two pull rods. The first engaging block has a first engaging angle surface and a first supporting surface. The second engaging block has a second engaging hook. The pull rod has a first contact surface and a first latching surface, with the first contact surface and the first latching surface perpendicular to each other. The pull rod also has a second slot. A tabletop is detachably mounted on the slide plate. The slide plate has a first through hole and a second through hole.

[0006] When the first supporting surface is pressed against the first contact surface and the second locking hook is engaged with the second locking slot, the table is in a state perpendicular to the support leg (i.e., the table is parallel to the ground).

[0007] When the first engaging angled surface (which consists of two planes with an included angle of 90 degrees between them) is in close contact with the first adhesive surface and the first contact surface, the tabletop is in a state parallel to the legs (i.e., the tabletop is perpendicular to the ground).

[0008] In this type of flip table, each leg is equipped with a support, and each support is equipped with a sliding plate via a pin. Each sliding plate is elastically limited by a spring and equipped with a pull rod. Therefore, this type of flip table has two pull rods. The two ends of the handle are respectively engaged with the two pull rods. By dragging the handle, the pull rod can be moved on the sliding frame. The movement of the handle on the sliding frame will cause changes in the engagement of the first locking surface, the first contact surface, and the second locking groove on the pull rod with the first locking block and the second locking block.

[0009] First, when the first supporting surface is pressed against the first contact surface and the second engaging hook is engaged with the second engaging slot, the slide plate is perpendicular to the support leg, and the tabletop on the slide plate is parallel to the ground. If the tabletop needs to be flipped, the handle is manually pulled. The handle moves the lever on the slide plate. After the lever moves, the second engaging hook is no longer engaged with the second engaging slot, and the first contact surface is no longer in contact with the first supporting surface. At this time, under the weight of the tabletop, the tabletop (along with the slide plate and the lever) rotates together. The axis of rotation is the pin. When the first engaging surface is pressed against the first engaging angle surface, the tabletop is perpendicular to the ground. At this time, the handle is released, and under the action of the spring, the first engaging surface is pressed against the first engaging angle surface. At this time, the slide plate is in an elastically locked state, and the slide plate and the tabletop cannot wobble. When the tabletop needs to be rotated from perpendicular to the ground to parallel to the ground, continue pulling the handle. The handle moves the lever on the slide plate, causing the first latching surface and the first contact surface on the lever to disengage from the first engaging angle surface. At this point, the user can rotate the tabletop back to the state where the first supporting surface is flush with the first contact surface and the second engaging hook is engaged with the second engaging slot. Due to the spring force, the tabletop remains locked (i.e., cannot wobble) regardless of whether it is perpendicular or parallel to the ground. During the tabletop rotation process, the first engaging block needs to enter and exit the slide plate through the first through hole, while the second engaging block needs to enter and exit the slide plate through the second through hole.

[0010] Therefore, in this type of flip table, the tabletop is locked in both states. When the tabletop is locked, it cannot wobble, reducing the probability of the tabletop being damaged.

[0011] Specifically, in this type of flip table, a connecting piece is provided on the slide plate. The table plate is fixed together with the connecting piece by bolts or screws, and there are no less than two connecting pieces on the same slide plate. The connecting pieces on the same slide plate are in a parallel state.

[0012] Optionally, the first locking block is provided with a first arc transition surface, and the two ends of the first arc transition surface are respectively connected to the first locking angle surface and the first supporting surface; the second locking block is provided with a second guide clamping slope, and the second slot of the pull rod is provided with a second guide clamping slope, and the second guide clamping slope is used to contact the second guide clamping slope.

[0013] Since the first contact surface and the first contact surface on the pull rod may come into contact with the first locking block during the rotation of the table, a first arc transition surface is provided on the first locking block. The first arc transition surface contacts the first locking angle surface and the first supporting surface. This can minimize the wear of the first locking block and the pull rod, and at the same time reduce the resistance encountered by the table when it rotates.

[0014] The second locking block is provided with a second guide clamp slope (the second guide clamp slope is located on one side of the second locking hook), and the second locking groove of the pull rod is provided with a second guide slope. The second guide clamp slope is used to contact the second guide slope. This is to ensure that the second locking hook slides into the second locking groove more smoothly and to reduce the resistance encountered when the second locking hook and the second locking groove are engaged.

[0015] Optionally, it also includes an extension rod, on which a plurality of inserts and a plurality of insert slots are provided, and on which a plurality of insertion holes and a plurality of insertion hooks are provided, wherein some of the inserts on the pull rod cooperate with some of the insertion holes on the extension rod, some of the insert slots on the pull rod cooperate with some of the insertion hooks on the extension rod, and the handle is inserted into the extension rod.

[0016] The pull rod has square inserts in two rows, with equal spacing between adjacent inserts in each row. The two rows are parallel. The extension rod has square holes in two parallel rows, with equal spacing between adjacent holes in each row. Some inserts on the pull rod mate with some holes on the extension rod, and some grooves on the pull rod mate with some hooks on the extension rod. This effectively forms a single rod, which can be adjusted in length to regulate the distance between the handle and the crossbeam. Because the distance between the handle and the crossbeam can be adjusted according to usage requirements, the sliding plate can accommodate tabletops of different widths.

[0017] Optionally, the slide plate is a flat-bottomed U-shaped slide plate, and a limiting slide post is provided on the slide plate. A limiting slide hole is provided on the pull rod or the extension rod, and the limiting slide post is located in the limiting slide hole.

[0018] Specifically, it also includes an auxiliary plate, which is fixed to the slide plate by screws. The auxiliary plate and the slide plate form a U-shaped clamping space. The pull rod (and extension rod) slides in the U-shaped clamping space, which can further improve the stability of the pull rod when sliding. The limiting slide post is opened on the auxiliary plate and is perpendicular to the auxiliary plate, the pull rod and the extension rod.

[0019] The flat-bottomed U-shaped slide plate allows the pull rod (and extension rod) to slide stably on the ground within the slide plate, because the flat-bottomed U-shaped slide plate itself is equivalent to a groove.

[0020] The purpose of the aforementioned limiting sliding hole and limiting sliding post is to limit the sliding amount of the pull rod (and extension rod) on the slide plate. When the limiting sliding post is close to the limit position of the limiting sliding hole, the pull rod will be unable to continue sliding on the slide plate.

[0021] Specifically, the limiting slide is cylindrical, and the limiting sliding hole is oval.

[0022] Optionally, the support has a square insertion hole, the crossbeam is a square tubular crossbeam, the crossbeam is fitted together with the square insertion hole, and the support and the crossbeam are fixed together by bolt assembly.

[0023] The specific square tubular crossbeam is inserted into the insertion square hole, and the crossbeam and the support are fixed together by bolt assembly, which can be disassembled and assembled as needed.

[0024] Meanwhile, in order to facilitate the quick assembly of the crossbeam onto the support, two side plates can be installed on the support. The two side plates are located at the opening of the insertion square hole, and the two side plates are in a parallel state. The two side plates are attached to the crossbeam from both sides.

[0025] Optionally, it also includes a cover, wherein the legs are hollow square tubular legs, the support is inserted into the legs, the support has a side hole, the cover is disposed on the support, and the elastic hook on the cover engages with the side hole.

[0026] The purpose of the cover is to cover the support. Since the cover is engaged with the side hole on the support by its own elastic hook, the cover can be removed from the support as needed.

[0027] Optionally, the crossbeam includes an inner crossbeam and an outer crossbeam, both of which are hollow square tubes. There are two inner crossbeams, each sleeved at both ends of the outer crossbeam, and each inner crossbeam is fitted with one of the two supports. The handle includes an inner handle and an outer handle, both of which are hollow tubes. There are two inner handles, each sleeved at both ends of the outer handle, and the inner handles are used for indirect cooperation with the supports.

[0028] Specifically, two inner crossbeams are respectively fitted onto both ends of the outer crossbeam, and the inner and outer crossbeams are fixed together with screws or bolts. This means the length of the entire crossbeam can be adjusted according to usage needs. To accommodate this adjustable crossbeam length design, two inner handles are respectively fitted onto both ends of the outer handle, and the inner and outer handles are fixed together with screws or bolts. Together, the inner and outer handles form an adjustable handle, which is then inserted and fixed to the extension rod on the handle. Because the lengths of the crossbeams and handles can be adjusted as needed, the tabletop used for the entire desk can also be selected according to requirements.

[0029] Specifically, the inner crossbeam is inserted into the square hole of the support and fixed to the support by bolt assembly.

[0030] Optionally, a stabilizing frame is provided on the support leg, and wheels are installed on the stabilizing frame.

[0031] Optionally, the spring is located between the slide plate and the pull rod, and the spring is parallel to the slide plate and the pull rod. One end of the spring directly or indirectly abuts against the slide plate, and the other end of the spring directly or indirectly abuts against the pull rod.

[0032] Specifically, one end of the spring abuts against the auxiliary plate on the slide plate, and the spring is parallel to the slide plate and the auxiliary plate. The other end of the spring abuts against the pull rod. In order to improve the installation stability of the spring, contacts are provided on both the auxiliary plate and the pull rod. The two ends of the spring are respectively embedded in the contacts of the auxiliary plate and the pull rod to ensure that the spring will not detach during the extension and retraction process.

[0033] Optionally, the handle and the crossbeam are parallel, and the handle and the crossbeam are perpendicular to the support legs.

[0034] The beneficial effect of this invention is that the tabletop is locked in both states, and the tabletop cannot wobble when locked, thus reducing the probability of the tabletop being damaged. Attached image description:

[0043] The present invention will now be described in detail with reference to the accompanying drawings.

[0044] As attached Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, a flip-up table includes two legs 2, a crossbeam, and supports 7. Each leg 2 has a support 7. The two ends of the crossbeam respectively engage with the supports 7 on the two legs 2. The table also includes a sliding plate 1, a pull rod 14, a spring 17, and a handle. The support 7 has a first locking block 701 and a second locking block 702. A pin is mounted on the first locking block 701. The sliding plate 1 is rotatably mounted on the pin. The pull rod 14 is slidably and elastically mounted on the sliding plate 1 via the spring 17. The handle has two... Each end is respectively engaged with two pull rods 14. The first locking block 701 is provided with a first locking angle surface 7012 and a first supporting surface 7011. The second locking block 702 is provided with a second locking hook 7021. The pull rod 14 is provided with a first contact surface 1405 and a first locking surface 1406. The first contact surface 1405 and the first locking surface 1406 are perpendicular to each other. The pull rod 14 is provided with a second locking groove 1403. A table is detachably provided on the slide plate 1. The slide plate 1 is provided with a first through hole and a second through hole.

[0045] When the first supporting surface 7011 is pressed against the first contact surface 1405, and the second locking hook 7021 is engaged with the second locking groove 1403, the table is in a state perpendicular to the support leg 2 (i.e., the table is parallel to the ground).

[0046] When the first engaging angled surface 7012 (which consists of two planes, with an included angle of 90 degrees between the two planes) is in close contact with the first engaging surface 1406 and the first contact surface 1405, the tabletop is in a state parallel to the support leg 2 (i.e., the tabletop is perpendicular to the ground).

[0047] In this type of flip table, each leg 2 is equipped with a support 7, and each support 7 is equipped with a sliding plate 1 via a pin. Each sliding plate is elastically limited by a spring 17 and is equipped with a pull rod 14. Therefore, this type of flip table has two pull rods 14. The two ends of the handle are respectively engaged with the two pull rods 14. By dragging the handle, the pull rod 14 can be moved on the sliding frame. The movement of the handle on the sliding frame will cause the engagement of the first locking surface 1406, the first contact surface 1405, and the second locking groove 1403 on the pull rod 14 with the first locking block 701 and the second locking block 702 to change.

[0048] First, when the first supporting surface 7011 is pressed against the first contact surface 1405, and the second engaging hook 7021 is engaged with the second engaging groove 1403, the slide plate 1 is in a state perpendicular to the support leg 2, and the table on the slide plate 1 is in a state parallel to the ground. If the table needs to be flipped at this time, the handle is manually pulled. The handle moves the lever 14 on the sliding plate. After the lever 14 moves, the second locking hook 7021 no longer locks the second locking groove 1403, and the first contact surface 1405 also disengages from the first supporting surface 7011. At this time, under the action of the table's own weight, the table (along with the sliding plate 1 and the lever 14) rotates together. The axis of rotation is the pin. When the first locking surface 1406 and the first contact surface 1405 are pressed against the first locking angle surface 7012, the table is in a state perpendicular to the ground. At this time, the handle is released. Under the action of the spring 17, the first locking surface 1406 and the first contact surface 1405 are pressed against the first locking angle surface 7012. At this time, the sliding plate 1 is in an elastic locking state, and the sliding plate 1 cannot wobble, nor can the table. When the tabletop needs to be rotated from perpendicular to the ground to parallel to the ground, continue pulling the handle. The handle moves the lever 14 on the slide plate 1, causing the first latching surface 1406 and the first contact surface 1405 on the lever 14 to disengage from the first engaging angle surface 7012. At this point, the user can rotate the tabletop back to the state where the first supporting surface 7011 is pressed against the first contact surface 1405, and the second engaging hook 7021 is engaged with the second engaging slot 1403. Due to the elastic force of the spring 17, the tabletop remains locked (i.e., cannot wobble) regardless of whether it is perpendicular to or parallel to the ground. During the tabletop rotation process, the first engaging block 701 needs to enter and exit the slide plate 1 through the first through hole, while the second engaging block 702 needs to enter and exit the slide plate 1 through the second through hole.

[0049] Therefore, in this type of flip table, the tabletop is locked in both states. When the tabletop is locked, it cannot wobble, reducing the probability of the tabletop being damaged.

[0050] Specifically, in this type of flip table, a connecting piece 13 is provided on the slide plate 1. The tabletop (not shown in the attached figure) is fixedly connected to the connecting piece 13 by bolts or screws 12, and there are no less than two connecting pieces 13 on the same slide plate 1. The connecting pieces 13 on the same slide plate 1 are in a parallel state.

[0051] As attached Figure 3 , 5As shown in Figure 6, the first locking block 701 is provided with a first arc transition surface 7013, and the two ends of the first arc transition surface 7013 are respectively connected to the first locking angle surface 7012 and the first supporting surface 7011; the second locking block 702 is provided with a second guide clamping slope 7022, and the second slot 1403 of the pull rod 14 is provided with a second guide clamping slope 1402, and the second guide clamping slope 7022 is used to contact the second guide clamping slope 1402.

[0052] Since the first latching surface 1406 and the first contact surface 1405 on the pull rod 14 may come into contact with the first latching block 701 during the rotation of the table, a first arc transition surface 7013 is provided on the first latching block 701. The first arc transition surface 7013 contacts the first latching angle surface 7012 and the first supporting surface 7011. This can minimize the wear of the first latching block 701 and the pull rod 14, and at the same time reduce the resistance encountered by the table when it rotates.

[0053] The second locking block 702 is provided with a second guide clamping slope 7022 (the second guide clamping slope 7022 is located on one side of the second locking hook 7021), and the second locking groove 1403 of the pull rod 14 is provided with a second guide clamping slope 1402. The second guide clamping slope 7022 is used to contact the second guide clamping slope 1402. This is to ensure that the second locking hook 7021 slides into the second locking groove 1403 more smoothly and to reduce the resistance encountered when the second locking hook 7021 engages with the second locking groove 1403.

[0054] As attached Figure 6 As shown in Figure 7, it also includes an extension rod 10. The pull rod 14 is provided with a plurality of inserts 1401 and a plurality of insert slots 1404. The extension rod 10 is provided with a plurality of insertion holes 1001 and a plurality of insert hooks 1003. Some of the inserts 1401 on the pull rod 14 are engaged with some of the insertion holes 1001 on the extension rod 10. Some of the insert slots 1404 on the pull rod 14 are engaged with some of the insert hooks 1003 on the extension rod 10. The handle is inserted into the extension rod 10.

[0055] Specifically, the inserts 1401 on the pull rod 14 are square inserts 1401, with two rows of inserts 1401, and the distance between any two adjacent inserts 1401 in each row is equal. The two rows of inserts 1401 are in a parallel state. The sockets 1001 on the extension rod 10 are square sockets 1001, with two rows of sockets 1001 in a parallel state. The distance between any two adjacent sockets 1001 in each row of sockets 1001 on the extension rod 10 is equal. Part of the inserts on the pull rod 14... The plate 1401 is fitted with a portion of the insertion hole 1001 on the extension rod 10, and a portion of the embedding groove 1404 on the pull rod 14 is fitted with a portion of the embedding hook 1003 on the extension rod 10. In this way, the pull rod 14 and the extension rod 10 together form a rod. The length of this rod can be adjusted as needed, so that the relative distance between the handle and the crossbeam can be adjusted. Since the distance between the handle and the crossbeam can be adjusted according to the usage requirements, the sliding plate can be adapted to the installation of tabletops of different widths.

[0056] As attached Figure 2 As shown, the slide plate 1 is a flat-bottomed U-shaped slide plate 1. A limiting slide post 1501 is provided on the slide plate 1. A limiting slide hole 1002 is provided on the pull rod 14 or the extension rod 10. The limiting slide post 1501 is located in the limiting slide hole 1002.

[0057] Specifically, it also includes an auxiliary plate 15, which is fixed on the slide plate 1 by screws 12. The auxiliary plate 15 and the slide plate 1 form a U-shaped clamping space. The pull rod 14 (and the extension rod 10) slides in the U-shaped clamping space, which can further improve the stability of the pull rod 14 when sliding. The limiting slide post 1501 is opened on the auxiliary plate 15 and is perpendicular to the auxiliary plate 15, the pull rod 14 and the extension rod 10.

[0058] The flat-bottomed U-shaped slide plate 1 allows the pull rod 14 (and extension rod 10) to slide stably on the ground within the slide plate 1, because the flat-bottomed U-shaped slide plate 1 itself is equivalent to a slide groove.

[0059] The purpose of the aforementioned limiting sliding hole and limiting sliding post 1501 is to limit the sliding amount of the pull rod 14 (and the extension rod 10) on the slide plate 1. When the limiting sliding post 1501 is close to the limit position of the limiting sliding hole, the pull rod 14 will be unable to continue sliding on the slide plate 1.

[0060] Specifically, the limiting slide 1501 is cylindrical, and the limiting sliding hole is oval.

[0061] As attached Figure 3As shown in Figure 5, the support 7 has a square insertion hole 703, the crossbeam is a square tubular crossbeam, the crossbeam and the square insertion hole 703 are fitted together, and the support 7 and the crossbeam are fixed together by bolt assembly.

[0062] Specifically, the square tube-shaped crossbeam is inserted into the square insertion hole 703, and the crossbeam and the support 7 are fixed together by bolt assembly, which can be disassembled and assembled as needed.

[0063] Meanwhile, in order to facilitate the quick assembly of the crossbeam onto the support 7, two side pieces 704 can be set on the support 7. The two side pieces 704 are located at the opening of the insertion square hole 703. The two side pieces 704 are in a parallel state and are attached to the crossbeam from both sides.

[0064] As attached Figure 5 As shown, it also includes a cover 8, a support 2 is a hollow square tube support 2, a support 7 is inserted into the support 2, a side hole 705 is provided on the support 7, the cover 8 is set on the support 7, and the elastic hook 801 on the cover 8 is engaged with the side hole 705.

[0065] The specific function of the cover 8 is to cover the support 7. Since the cover 8 is engaged with the side hole 705 on the support 7 by its own elastic hook 801, the cover 8 can be removed from the support 7 as needed.

[0066] As attached Figure 1 As shown in Figure 2, the crossbeam includes an inner crossbeam 502 and an outer crossbeam 501. Both the inner crossbeam 502 and the outer crossbeam 501 are hollow square tubes. There are two inner crossbeams 502, which are respectively sleeved on both ends of the outer crossbeam 501. The two inner crossbeams 502 are respectively fitted with the two supports 7. The handle includes an inner handle 1101 and an outer handle 1102. Both the inner handle 1101 and the outer handle 1102 are hollow tubes. There are two inner handles 1101, which are respectively sleeved on both ends of the outer handle 1102. The inner handle 1101 is used for indirect cooperation with the support 7.

[0067] Specifically, two inner crossbeams 502 are respectively fitted onto both ends of the outer crossbeam 501, and the inner crossbeams 502 and outer crossbeams 501 are fixed together with screws 12 or bolts. This means the length of the entire crossbeam can be adjusted according to usage needs. To accommodate this adjustable crossbeam length design, two inner handles 1101 are respectively fitted onto both ends of the outer handle 1102, and the inner handles 1101 and outer handles 1102 are fixed together with screws 12 or bolts. The inner handles 1101 and outer handles 1102 together form an adjustable handle, and the inner handle 1101 is inserted and fixed to the extension rod 10 on the pull rod 14. Because the lengths of the crossbeams and handles can be adjusted as needed, the tabletop used for the entire table can also be selected according to requirements.

[0068] Specifically, the inner crossbeam 502 is inserted into the square insertion hole 703 of the support 7 and is fixed to the support 7 by bolt assembly.

[0069] As attached Figure 1 As shown, a stabilizing frame 3 is installed on the support leg 2, and wheels 4 are installed on the stabilizing frame 3.

[0070] As attached Figure 4 As shown in Figure 6, spring 17 is located between slide plate 1 and pull rod 14, and spring 17 is parallel to slide plate 1 and pull rod 14. One end of spring 17 directly or indirectly abuts against slide plate 1, and the other end of spring 17 directly or indirectly abuts against pull rod 14.

[0071] Specifically, one end of the spring 17 abuts against the auxiliary plate 15 on the slide plate 1, and the spring 17 is parallel to the slide plate 1 and the auxiliary plate 15. The other end of the spring 17 abuts against the pull rod 14. In order to improve the installation stability of the spring 17, both the auxiliary plate 15 and the pull rod 14 are provided with contacts 16. The two ends of the spring 17 are respectively embedded in the contacts 16 of the auxiliary plate 15 and the pull rod 14 to ensure that the spring 17 will not detach during the extension and retraction process.

[0072] As attached Figure 1 As shown, the handle and the crossbeam are parallel, and the handle and the crossbeam are perpendicular to the support leg 2.

[0073] See appendix Figure 6 As shown, a retaining ring 9 is installed on the pin 6 to prevent the pin 6 from falling off the slide plate.

[0074] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent modifications made based on the content of the present invention specification, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present invention.
