Description

Technical Field

[0001] The invention relates to the field of sports equipment, and in particular to a ball table and a use method thereof. Background Art

[0002] At present, most foldable pool tables on the market use hinge structures to fix the table top and legs. When locking, the user needs to press the hinge to the dead point by hand to ensure that the pool table is locked. If the customer forgets to lock the hinge, the pool table is at risk of tipping over when pushed or pulled. At the same time, when the pool table is folded and stored, the user needs to manually release the dead point of the hinge. Once the customer forgets to release the dead point, the pool table will not be able to fold, and even the hinge will be damaged when folding with great force.

[0003] In order to prevent users from forgetting to lock or unlock the table, a table has been developed which can be locked vertically when folded and horizontally when laid flat for use, and is easy for users to operate and prevent users from forgetting to lock the table. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a table and a method of use which have a reasonable structural design and are convenient for users to operate.

[0005] The present invention provides a ball table, comprising:

[0006] mesa;

[0007] A leg assembly, disposed below the table top, comprising two first legs and two second legs, for supporting the table top;

[0008] A pull rod assembly is arranged below the table top, and comprises a hand pull rod and two linkage rods fixed at both ends of the hand pull rod, wherein the two linkage rods are parallel to each other and perpendicular to the hand pull rod on a horizontal plane;

[0009] in,

[0010] A horizontal locking structure is respectively arranged between the two linkage rods and the bottom surface of the table top, and the horizontal locking structure comprises:

[0011] A folding link assembly, comprising a first link and a second link, wherein one end of the first link is hinged to one end of the second link, the other end of the first link is hinged to the bottom surface of the table top, and the other end of the second link is hinged to the first leg;

[0012] A limit torsion spring is coaxially hinged with the other end of the first connecting rod, and a spring arm of the limit torsion spring is located below the first connecting rod to provide an upward torsion spring force for limiting the rotation of the first connecting rod;

[0013] When the table top is in the unfolded state, the angle between the first connecting rod and the second connecting rod is 180°, and the straight line where the first connecting rod and the second connecting rod are located forms a stable triangular support structure with the table top and the first leg. A spring arm of the limiting torsion spring provides an upward elastic force for the first connecting rod to limit the rotation of the first connecting rod, and the table top is locked in the unfolded state.

[0014] In the technical solution, during the process of unfolding the table top, the first connecting rod and the second connecting rod are gradually straightened. When the two are in the same line, a spring arm of the limiting torsion spring provides an upward elastic force for the first connecting rod, limiting the rotation of the first connecting rod, thereby ensuring that the folding connecting rod assembly enters the locking point when the angle between the first connecting rod and the second connecting rod is 180° when the table is flattened. The table will not collapse due to the rotation of the legs caused by external push and pull, thereby increasing the safety of use.

[0020] The limiting column moves, and the first hinged part is driven to move through the second hinged part, and the first hinged part drives the first connecting rod to rotate.

[0021] In some embodiments of the present application, a bolt is fixed to the other end of the limiting column to prevent the limiting column from detaching from the first limiting groove.

[0022] In some embodiments of the present application, a U-shaped baffle is provided on one side of the end of the second link close to the first link, and the opening of the baffle is perpendicular to the axial direction of the second link. When the angle between the first link and the second link is 180°, the baffle limits the upper part of the hinge point of the first link, and the baffle cooperates with the limiting torsion spring to keep the angle between the first link and the second link unchanged.

[0023] In some embodiments of the present application, sleeves are respectively fixed on the bottom surface of the table near the two ends of the hand rod and at locations corresponding to the two linkage rods, and the sleeves have a limiting cavity arranged colinearly with the linkage rod. The limiting cavity is open at one end near the linkage rod and closed at the other end. One end of the linkage rod near the hand rod is located in the limiting cavity and can move back and forth in the limiting cavity.

[0024] In some embodiments of the present application, a vertical locking assembly is provided at one end of the linkage rod away from the hand pull rod, and the vertical locking assembly includes:

[0025] A lock housing is fixed at the bottom of the table near the end of the linkage rod, a hollow accommodating cavity is formed inside the lock housing, a sliding groove extending along the length direction of the lock housing is opened on the side of one end of the lock housing, a connecting bolt crosses the sliding groove, the end of the linkage rod is fixed to the end of the connecting bolt located outside the lock housing, and the movement of the linkage rod drives the connecting bolt to move in the sliding groove;

[0026] A locking plate is built into the accommodating cavity, one end of the locking plate is hinged to one end of the lock housing, and the other end of the locking plate is a free end and abuts against the top of the connecting bolt;

[0027] A locking groove extending downward is formed on the top surface of the other end of the lock housing, and the locking plate has a protruding locking pawl at the position of the locking groove;

[0028] A locking hook is arranged on the second leg close to the locking shell. When the table top is placed vertically, the locking hook is located in the locking groove and cooperates with the locking pawl to put the table in a folded and locked state.

[0029] In some embodiments of the present application, in some embodiments of the present application, the first leg is arranged on one side of the table top close to the hand pull rod, and the second leg is arranged on the other side of the table top;

[0030] The first supporting leg and the second supporting leg are hinged to the table top, and the first supporting leg and the second supporting leg can rotate around the table top within a range of 0-90 degrees.

[0031] In some embodiments of the present application, a connecting longitudinal rod is provided between the first leg and the second leg. When the second leg rotates, the connecting longitudinal rod drives the first leg to rotate synchronously, which facilitates operation.

[0033] Table deployment:

[0034] Pull the hand-pulling rod upward to drive the linkage rod to move upward, and the linkage rod drives the connecting bolt of the vertical locking assembly to move upward, the free end of the locking plate rotates clockwise, the locking pawl releases the lock on the locking hook, the vertical lock of the table is released, and then the hand-pulling rod is released; in the process of the linkage rod moving upward, the sliding sleeve moves synchronously, the limit column slides from one end of the first limit groove to the other end, and the actuator moves accordingly, which pulls the first connecting rod to rotate;

[0035] The tabletop is pressed down on one side close to the hand-pulled rod, and the angle between the first link and the second link gradually increases. The limit column continues to slide along the first limit groove. When the angle is 180°, the tabletop is horizontal, the limit torsion spring applies an upward torsion spring force to the first link, and the baffle applies downward pressure to the first link. At this time, the limit column is located at the other end of the first limit groove, the actuator stops rotating, the folding link assembly enters the locking point, the tabletop is locked horizontally, and the unfolding is completed for use;

[0038] Lift up the side of the table top close to the hand pull rod, the first leg rotates and folds, and the second leg is driven to rotate and fold by connecting the longitudinal rod. When the locking hook enters the locking groove, the linkage rod moves downward due to gravity, driving the connecting bolt to move downward along the sliding groove, and the free end of the locking plate is rotated upward. The locking plate rotates counterclockwise around the hinge point, and the locking pawl moves downward to limit and lock the locking hook. The table top is locked vertically, and the folding and storage of the ball table is completed.

[0039] Based on the above technical solution, the setting of the horizontal locking structure, the setting of the folding connecting rod assembly and the actuator enables the table to be automatically locked after being unfolded without manual operation, thereby increasing the horizontal stability and safety of the table when in use;

[0040] The vertical locking component is set to vertically lock the table in the folded state, avoiding the risk of the table collapsing after folding and increasing the safety of storage;

At the same time, the table rotation is operated on one side of the hand rod. There is no need to walk during the operation. It can also avoid the safety hazard caused by the collapse or overturning of the table due to forgetting to lock. It is highly practical and suitable for popularization and use.

[0056] As attached Figure 1-4 As shown, this embodiment provides a ball table, comprising:

[0057] Table 10, used for table tennis training;

[0058] A leg assembly, disposed below the table top 10, includes two first legs 20 and two second legs 60, and is used to support the table top 10;

[0059] The pull rod assembly 30 is arranged below the table 10 and includes a hand pull rod 31 and two linkage rods 32 fixed at both ends of the hand pull rod 31. The two linkage rods 32 are parallel to each other and perpendicular to the hand pull rod 31 in the horizontal plane. Figure 1As shown, the hand-pull rod 31 and the two linkage rods 32 are respectively located on the three sides of the table 10. When the hand-pull rod 31 is pulled, the linkage rods 32 move synchronously therewith.

[0060] A horizontal locking structure 40 is provided between the two linkage rods 32 and the bottom surface of the table 10. Figure 2 As shown, the horizontal locking structure 40 includes:

[0061] The folding link assembly 41 includes a first link 411 and a second link 412, wherein one end of the first link 411 is hinged to one end of the second link 412, the other end of the first link 411 is hinged to the bottom surface of the table 10, and the other end of the second link 412 is hinged to the first leg 20;

[0062] The limiting torsion spring 42 is coaxially hinged with the other end of the first connecting rod 411 and fixed at the bottom of the table 10. One spring arm of the limiting torsion spring 42 is located below the first connecting rod 411 (not shown in the figure), providing the first connecting rod 411 with an upward torsion spring force to limit its rotation.

[0063] like Figure 1 As shown, when the table top 10 is in a horizontally unfolded state, the angle between the first link 411 and the second link 412 is 180°, that is, the first link 411 and the second link 412 are in a straight line, and the straight line where the first link 411 and the second link 412 are located forms a stable triangular support structure with the table top and the first leg 20. A spring arm of the limiting torsion spring 42 provides an upward elastic force for the first link 411 to limit the rotation of the first link 411. The folding link assembly enters the locking point, and the table top 10 is locked in the unfolded state. The table will not collapse due to the rotation of the legs caused by external push and pull, thereby increasing the safety of use.

[0064] Continue to see Figure 2 The horizontal locking assembly 40 is also connected to the actuating assembly 43, and the actuating assembly 43 includes:

[0065] The sliding sleeve 431 is sleeved on the outer side of the linkage rod 32. The sliding sleeve 431 is provided with a first limiting groove 4311 extending along its length direction. A second limiting groove (not shown in the figure) parallel to the first limiting groove 4311 is provided at a corresponding position of the linkage rod 32. The limiting column 432 passes through the first limiting groove 4311 and the second limiting groove and extends at both ends.

[0066] An actuating member 433, a first end of which is hinged to the middle portion of the first connecting rod 411, and a second end of which is hinged to one end of the limiting column 432;

[0067] When the linkage rod 32 moves, the sliding sleeve 431 can move along the linkage rod 32, and the limiting column 432 moves in the first limiting groove 4311. The limiting column 432 drives one end of the actuator 433 to rotate, and the actuator 433 drives the first connecting rod 411 to rotate, and then the first connecting rod 411 and the second connecting rod 412 rotate relative to each other, thereby releasing the lock of the folding connecting rod assembly.

[0068] like Figure 3 As shown, the actuator 433 is a "Z"-shaped bent plate structure, including a first hinged portion 4331, a connecting portion 4332, and a second hinged portion 4333 connected in sequence, the first hinged portion 4331 is hinged to the first connecting rod 411, the second hinged portion 4333 is hinged to the limiting column 432, and the connecting portion 4332 is used to connect the first hinged portion 4331 and the second hinged portion 4333;

[0069] During the unfolding of the table top, the limiting column 432 moves, and drives the first hinge part 4331 to move through the second hinge part 4333, and the first hinge part 4331 drives the first connecting rod 411 to rotate.

[0070] In order to prevent the limiting column 432 from being separated from the first limiting groove 4311, a bolt is fixed to the other end of the limiting column 432. Figure 2 shown.

[0071] A U-shaped baffle 4121 is provided on one side of the end of the second link 412 close to the first link 411, and the opening of the baffle is perpendicular to the axial direction of the second link 412. When the angle between the first link 411 and the second link 412 is 180°, the baffle 4121 is just above the first link, and this position is close to the hinge point between the first link and the second link. At this time, the baffle 4121 limits the first link 411, and the baffle 4121 and the limiting torsion spring 42 are respectively matched at both ends of the first link 411, so that the angle between the first link 411 and the second link 412 remains unchanged.

[0072] In order to limit the pulling stroke of the hand rod 31, sleeves 11 are fixed on the bottom edge of the table top 10 near the two ends of the hand rod 31 and at positions corresponding to the two linkage rods 31. The sleeve 11 has a limiting cavity arranged colinearly with the linkage rod 31. The limiting cavity is open at one end near the linkage rod 32 and closed at the other end. One end of the linkage rod 32 near the hand rod 31 is located in the limiting cavity and can move back and forth in the limiting cavity. The pulling stroke of the hand rod 31 is less than or equal to the length of the limiting cavity. At the same time, the limiting cavity also has a certain guiding effect on the linkage rod 32.

[0073] Continue to see Figure 4 In order to enable the table to be automatically locked in the folded state, a vertical locking assembly 50 is provided at one end of the linkage rod 32 away from the hand pull rod 31. Figure 5-6As shown, the vertical locking assembly 50 includes:

[0074] The lock housing 51 is an inverted "U"-shaped plate structure, fixed to the bottom of the table 10 near the end of the linkage rod 32. A hollow accommodating chamber 52 is formed inside the lock housing 51. The accommodating chamber 52 is open at both ends. A sliding groove 53 extending along the length direction is opened on the side of one end of the lock housing 51. A connecting bolt 54 crosses the sliding groove 53. The end of the linkage rod 32 is fixed to the end of the connecting bolt 54 located outside the lock housing 51. The movement of the linkage rod 32 drives the connecting bolt 54 to move in the sliding groove 53. A protruding hole 511 is opened on the top surface of the lock housing 51 above the sliding groove 53. The protruding hole 511 is a rectangular hole.

[0075] The locking plate 55 is built into the accommodating cavity 52. ​​One end of the locking plate 55 is hinged to one end of the lock housing 52. The other end of the locking plate 55 is a free end 552. The free end 552 extends upwardly at an angle relative to the hinged end of the locking plate 55, extends out of the lock housing 51 through the extension hole 511, and the free end 552 abuts against the top of the connecting bolt 54.

[0076] A locking groove 512 extending downward is formed on the top surface of the other end of the lock housing 51, and the locking plate 55 has a protruding locking pawl 551 at the position of the locking groove 512;

[0077] A locking hook 61 is provided on the second leg 60 close to the lock shell 51. When the table top 10 is placed vertically, the locking hook 61 is located in the locking groove 512 and cooperates with the locking pawl 551. The locking pawl 551 restricts the locking hook 61 in the locking groove 512, so that the table is in a folded and locked state.

[0078] The locking hook 61 is an inverted U-shaped structure, and the locking pawl 551 limits the transverse rod of the locking hook 61; a support rod 63 is arranged between the two second legs 60, and the support rod 63 is perpendicular to the linkage rod 32. The locking hooks 61 are symmetrically arranged at both ends of the support rod 63, and the locking hooks 61 are vertically arranged, and the plane where the locking hook 61 is located is parallel to the second legs 60.

[0079] The accommodating cavity 51 of the present embodiment is further provided with a torsion spring 56, which is coaxially hinged with the locking plate 55. When the vertical locking assembly 50 is in the locked state, the linkage rod 32 moves downward to drive the connecting bolt 54 to move downward, and the free end of the locking plate 55 is subjected to the upward pressure of the connecting bolt. At this time, the torsion spring is in the expanded state, and both ends of the locking plate 55 are subjected to the inclined upward elastic force of the torsion spring 56. The locking pawl 551 of the locking plate 55 limits and locks the locking hook 61, so that the locking pawl 551 can firmly lock the locking hook 61. When the vertical locking assembly 50 is unlocked, the linkage rod 32 moves upward to drive the connecting bolt 54 to move upward. Under the action of the torsion spring 56, the free end of the locking plate 55 rotates, and the locking pawl 551 of the locking plate 55 also rotates accordingly. When the connecting bolt 54 moves upward for a certain distance and stops, the free end of the locking plate 55 also stops rotating. At this time, the torsion spring is in a compressed state, and the locking pawl 551 rotates to a position to release the locking hook 61, and the locking hook 61 disengages from the locking groove 512.

[0080] In this embodiment, the first leg 20 is a rod-shaped support structure, and two pulleys are arranged below the second leg 60 for easy movement; for easy operation, the first leg 20 is arranged on one side of the table top 10 close to the hand pull rod 31, and the second leg 60 is arranged on the other side of the table top 10. The table is unfolded and folded on the side of the first leg 20, saving effort during operation. The first leg 20 and the second leg 60 are hinged to the table top 10, and the first leg 20 and the second leg 60 can rotate around the table top at 0-90 degrees.

[0081] At the same time, a connecting longitudinal rod 21 is arranged between the first leg 20 and the second leg 60. The two ends of the connecting longitudinal rod 21 are hinged to the first leg 20 and the second leg 60. When the second leg 60 rotates, the connecting longitudinal rod 31 drives the first leg 20 to rotate synchronously, thereby reducing the manual operation steps.

[0082] The present invention also provides a method for using the above-mentioned table, comprising the following steps:

[0083] Table deployment:

[0084] When the table is in the folded state, the hand-pulled rod 31 is pulled upward to drive the linkage rod 32 to move upward, and the linkage rod 32 drives the connecting bolt 54 of the vertical locking assembly 50 to move upward. Under the action of the torsion spring 56, the free end of the locking plate 55 rotates clockwise, and the locking pawl 551 releases the lock on the locking hook 61, and the vertical lock of the table is released, and then the hand-pulled rod 31 is released; in the process of the linkage rod 32 moving upward, the sliding sleeve 431 moves synchronously, the limiting column 432 slides from one end of the first limiting groove 4311 to the other end, the second hinged portion 4333 of the actuator 433 moves, and the first hinged portion 4331 of the actuator 433 pulls and drives the first connecting rod 411 to rotate counterclockwise around the hinge point with the table top 10;

[0085] After releasing the hand lever 31, the side of the table top 10 close to the hand lever 31 is pressed down, the first connecting rod 411 continues to rotate counterclockwise, and the second connecting rod 412 rotates clockwise, the angle between the first connecting rod 411 and the second connecting rod 412 gradually increases, and the limiting column continues to slide along the first limiting groove 4311. When the limiting column 432 moves to the other end of the first limiting groove 4311, the table top 10 is fully unfolded;

[0086] like Figure 1 As shown, when the table 10 is pressed down to be horizontal, the angle between the first link 411 and the second link 412 is 180°. At this time, the limit torsion spring 42 provides an oblique upward torsion spring force to the end of the first link 411 close to the table 10, and the baffle 4121 provides an oblique downward pressure to the end of the first link 411 that enters the second link 412. The folding link assembly 41 enters the locking point, the table is locked horizontally, and the unfolding is completed for use;

[0087] Folding storage of the table:

[0088] When the table is in the unfolded state, the table top 10 is horizontal. The hand pull rod 31 is pulled outward horizontally, and the linkage rod 32 moves outward synchronously. The sliding sleeve 431 moves backward along the linkage rod 32, and the limiting column 432 moves in the opposite direction in the first limiting groove 4311. The limiting column 432 drives the second hinge part 4333 of the actuator 433 to move, and then the first hinge part 4331 of the actuator 433 pulls the first linkage rod 411 out of the locking point, thereby releasing the horizontal locking of the table top.

[0089] Then, the side of the table top 10 close to the hand pull rod 31 is lifted upward, the first leg 20 is lifted and rotated and folded, and the bottom of the second leg 60 is driven to rotate and fold by connecting the longitudinal rod 21. When the table top 10 rotates until the locking hook 61 enters the locking groove 512 of the vertical locking assembly 50, the hand pull rod 31 and the linkage rod 32 move downward due to gravity, driving the connecting bolt 54 to move downward along the sliding groove 53, pushing the free end 552 of the locking plate 55 to rotate upward, and the locking plate 55 rotates counterclockwise around the hinge point, so that the locking pawl 551 moves downward to limit and lock the locking hook 61. Figure 7 As shown, the table top is locked vertically to complete the folding and storage of the table.

[0090] In this embodiment, when the table top is unfolded, the straight line where the two pulleys 62 fixed at the bottom of the second leg 60 are located is parallel to the linkage rod 32. When the table top is folded, the straight line where the two pulleys 62 are located is parallel to the linkage rod 32 and perpendicular to the table top. The pulley 62 serves as a base to support the entire ball table. The force-bearing area is increased, thereby improving the folding stability of the ball table.

[0091] Based on the above technical solution, the setting of the horizontal locking structure, the setting of the folding connecting rod assembly and the actuator enables the table to be automatically locked after being unfolded without manual operation, thereby increasing the horizontal stability and safety of the table when in use;

[0092] The vertical locking component is set to vertically lock the table in the folded state, avoiding the risk of the table collapsing after folding and increasing the safety of storage;

[0093] The operation of releasing the vertical lock and the horizontal lock is simple. By pulling the hand rod, the linkage rod will be linked to release the corresponding lock. At the same time, the table rotation is operated on one side of the hand rod. There is no need to walk during the operation. It can also avoid the safety hazard caused by the collapse or overturning of the table due to forgetting to lock. It is highly practical and suitable for popularization and use.

[0094] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
