[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0027] Reference below Figure 1-Figure 4 A support structure 100 for a table and chair according to an embodiment of the present invention is described. The support structure 100 for a table and chair is applied to a table and chair.
[0028] like Figure 1-Figure 3As shown, the support structure 100 of the table and chair according to the present invention includes: a horizontal bar 10, a sliding member 20 and a vertical bar 30. The sliding member 20 is arranged at the end of the horizontal bar 10, and the vertical bar 30 is arranged at the end of the horizontal bar 10. The vertical bar 30 includes: an outer rod body 31 and an inner partition 32. The outer rod body 31 is formed with an opening extending vertically on the side facing the horizontal bar 10. The inner partition 32 is arranged in the outer rod body 31 and forms a slide groove extending vertically together with the outer rod body 31. The sliding member 20 passes through the opening and is slidably arranged in the slide groove.
[0029] It can be understood that the cross bar 10, the sliding member 20 and the vertical bar 30 constitute the main body of the support structure 100 of the table and chair. There are two vertical bars 30, and the two vertical bars 30 are arranged relative to each other in the left and right directions, so that an installation space can be formed between the two vertical bars 30. The left and right ends of the cross bar 10 are respectively connected to the vertical bars 30. This arrangement can form a frame structure with the vertical bars 30 and the cross bar 10, thereby improving the strength of the support structure 100 of the table and chair. The two vertical bars 30 are parallel, and the cross bar 10 can move relative to the two vertical bars 30 along the length direction of the vertical bars 30, so that other corresponding components can be installed when the cross bar 10 is in different positions relative to the vertical bars 30, such as installing a seat cushion or a footrest on the cross bar 10.
[0030] In addition, the sliding member 20 is located at the left and right ends of the horizontal bar 10, and the two vertical bars 30 are also located at the left and right ends of the horizontal bar 10, so that the sliding member 20 and the vertical bars 30 can slide relative to each other, thereby allowing the horizontal bar 10 and the vertical bars 30 to slide relative to each other, and then the horizontal bar 10 can be moved according to the actual needs of the user.
[0031] The outer rod 31 and the inner partition 32 constitute the main structure of the vertical rod 30. The outer rod 31 on the left side has an opening on the right side, and the outer rod 31 on the right side also has an opening on the left side. The openings extend along the length direction of the outer rod 31, so that the outer rod 31 can form a semi-enclosed structure, which not only ensures the structural strength of the outer rod 31, but also facilitates the sliding of the sliding member 20 at the opening. The inner partition 32 is arranged in the outer rod 31, and the inner partition 32 extends along the length direction of the outer rod 31, so that The inner partition 32 blocks the opening, so that a slide groove is formed between the outer rod body 31 and the inner partition 32. The slide groove extends along the length direction of the outer rod body 31, and the sliding member 20 slides in cooperation with the slide groove, which not only allows the edge of the outer rod body 31 to limit the sliding member 20, but also allows the slide groove to provide a movement path for the sliding member 20, so that the position of the cross bar 10 can be limited according to the actual needs of the user, thereby enriching the use scenarios of the support structure 100 of the table and chair, and improving the utilization rate of the support structure 100 of the table and chair.
[0032] Therefore, by arranging a sliding part 20 at the end of the horizontal bar 10 and arranging an inner partition 32 in the outer rod body 31, the inner partition 32 and the outer rod body 31 together form a slide groove in the length direction, and the sliding part 20 can move in the slide groove. This arrangement can make the horizontal bar 10 move relative to the vertical bar 30 in the length direction of the vertical bar 30, so that the position of the horizontal bar 10 can be limited according to the actual needs of the user, thereby enriching the use scenarios of the support structure 100 of the table and chair, and improving the utilization rate of the support structure 100 of the table and chair.
[0033] In particular, Figure 3 As shown, the outer rod body 31 is constructed as a cylinder with an opening, and arcuate surfaces 21 are respectively provided at both ends of the width direction of the sliding member 20 , and the arcuate surfaces 21 are adapted to the inner wall surface of the outer rod body 31 .
[0034] It can be understood that the outer rod body 31 is set to be cylindrical, and the cylinder forms an opening on one side facing the cross bar 10, so that the outer rod body 31 can form a semi-enclosed structure, and the sliding part 20 is provided with arcuate surfaces 21 on both sides in the width direction, and the arcuate surfaces 21 and the inner side of the outer rod body 31 are in contact with each other, which not only allows the inner edge of the outer rod body 31 to limit the arcuate surface 21 of the sliding part 20, but also facilitates the relative movement of the sliding part 20 and the outer rod body 31, so that the position of the cross bar 10 can be limited according to the actual needs of the user, thereby enriching the use scenarios of the support structure 100 of the table and chair, and improving the utilization rate of the support structure 100 of the table and chair.
[0035] In addition, if Figure 3 As shown, a groove 22 extending vertically is formed on the side of the slider 20 facing the inner partition 32, and the groove 22 is located in the middle of the width direction of the slider 20. In other words, the groove 22 is provided on the side of the slider 20 facing the inner partition 32, and the groove 22 extends along the length direction of the slider 20, thereby saving material of the slider 20 and achieving a lightweight design. Moreover, the groove 22 is located in the middle of the slider 20, which allows the slider 20 to achieve sliding balance, thereby facilitating the movement of the slider 20 relative to the slide groove, and thus the position of the crossbar 10 can be limited according to the actual needs of the user.
[0036] In addition, if Figure 3 As shown, the sliding member 20 includes: a slide plate 23, a mounting block 24 and a connecting portion 25. The slide plate 23 is slidably arranged in the slide groove. The mounting block 24 is connected to the slide plate 23. The mounting block 24 is installed in the cross bar 10. The connecting portion 25 is connected between the slide plate 23 and the mounting block 24 and passes through an opening. The width of the connecting portion 25 is smaller than the maximum width of the slide plate 23 and the maximum width of the mounting block 24.
[0037] It can be understood that the slide 23, the mounting block 24 and the connecting portion 25 constitute the main structure of the sliding member 20, and the connecting portion 25 is located between the slide 23 and the mounting block 24, so that the slide 23, the connecting portion 25 and the mounting block 24 can be connected in sequence, and the mounting block 24 is located at the left and right ends of the cross bar 10, and the slide 23 is located in the slide groove, and the slide 23 and the slide groove can slide relative to each other, so that the movement of the slide 23 relative to the slide groove drives the movement of the mounting block 24, and the movement of the mounting block 24 drives the cross bar 10 to move, and then the cross bar 10 can move relative to the vertical bar 30, and the connection The portion 25 is located on the inner side of the opening, so that the opening of the outer rod body 31 can limit the connecting portion 25, thereby ensuring that the cross bar 10 only moves along the length direction of the outer rod body 31, and can also prevent the cross bar 10 from moving in other unspecified directions, thereby ensuring the established movement between the cross bar 10 and the vertical bar 30. The width of the connecting portion 25 is less than the maximum width of the slide 23 and the maximum width of the mounting block 24, which not only facilitates the connection between the connecting portion 25 and the slide 23 and the mounting block 24, but also saves the material of the sliding part 20, thereby realizing a lightweight design of the support structure 100 of the table and chair.
[0038] In addition, if Figure 1 and Figure 2 As shown, the crossbar 10 includes: an outer rod sleeve 11 and an inner skeleton 12. The outer rod sleeve 11 is hollow inside, the inner skeleton 12 is arranged in the outer rod sleeve 11, and the mounting block 24 is installed in the outer rod sleeve 11, and the mounting block 24 is connected to the inner skeleton 12.
[0039] That is to say, the outer rod sleeve 11 and the inner frame 12 constitute the main structure of the cross bar 10, and an installation space is formed inside the outer rod sleeve 11, and the inner frame 12 is located in the installation space, that is, the outer rod sleeve 11 is sleeved on the inner frame 12, so that the outer rod sleeve 11 can protect the inner frame 12, thereby extending the service life of the inner frame 12, and the mounting blocks 24 are located at the left and right ends of the inner frame 12, so that the movement of the slide plate 23 relative to the slide groove can drive the movement of the mounting blocks 24, and the movement of the mounting blocks 24 can drive the movement of the inner frame 12, and the movement of the inner frame 12 can drive the cross bar 10 to move, so that the cross bar 10 can move relative to the vertical bar 30, and the mounting blocks 24 are located in the outer rod sleeve 11, so that the outer rod sleeve 11 can protect the mounting blocks 24, thereby extending the service life of the mounting blocks 24.
[0040] In addition, if Figure 1 、 Figure 2 and Figure 4 As shown, the support structure 100 of the table and chair also includes: a locking mechanism 40 and an unlocking mechanism 50. The locking mechanism 40 can be movably arranged in the cross bar 10. The sliding member 20 is provided with a through hole 26. The locking mechanism 40 passes through the through hole 26. The unlocking mechanism 50 is rotatably arranged on the cross bar 10. The unlocking mechanism 50 is transmission-coordinated with the locking mechanism 40.
[0041] When the locking mechanism 40 is inserted into the through hole 26 , the locking mechanism 40 locks the vertical rod 30 , and the cross bar 10 and the vertical rod 30 are relatively stationary. When the locking mechanism 40 is not inserted into the through hole 26 , the locking mechanism 40 does not lock the vertical rod 30 , and the cross bar 10 and the vertical rod 30 can move relative to each other. The unlocking mechanism 50 is located in the middle of the cross bar 10 , and the unlocking mechanism 50 can rotate relative to the cross bar 10 . The unlocking mechanism 50 is transmission-connected to the locking mechanism 40 . This arrangement makes it easy for the user to operate the unlocking mechanism 50 to unlock the locking mechanism 40 , thereby making it easy for the cross bar 10 to be stationary or move relative to the vertical rod 30 , thereby enabling the support structure 100 of the table and chair to be switched in various usage scenarios.
[0042] Among them, such as Figure 4 As shown, the locking mechanism 40 includes: a locking member 41, a transmission member 42 and an elastic member 43. The locking member 41 passes through the through hole 26 and locks the corresponding vertical rod 30. One end of the transmission member 42 is connected to the locking member 41, and the other end of the transmission member 42 is transmitted and cooperated with the unlocking mechanism 50. The elastic member 43 is arranged in the through hole 26 and abuts between the locking member 41 and the cross bar 10, so that it can provide a locking force to the locking member 41 to lock the corresponding vertical rod 30.
[0043] That is to say, the locking member 41, the transmission member 42 and the elastic member 43 constitute the main body of the locking mechanism 40. The locking member 41, the transmission member 42 and the elastic member 43 are two and used in combination. One end of the transmission member 42 is connected to the locking member 41, and the other end is connected to the unlocking mechanism 50. The two transmission members 42 are respectively located on the left and right sides of the unlocking mechanism 50, and the through hole 26 is provided on the sliding member 20. When the locking member 41 is inserted into the through hole 26, the locking member 41 locks the vertical rod 30. At this time, the cross bar 10 and the vertical rod 30 are locked. 0 is relatively stationary. When the locking member 41 is not inserted into the through hole 26, the locking member 41 does not lock the vertical rod 30. At this time, the cross bar 10 and the vertical rod 30 can move relative to each other. The elastic member 43 is located between the locking member 41 and the cross bar 10, and the elastic member 43 is located in the through hole 26. In this way, the elastic member 43 can fill the gap between the locking member 41 and the cross bar 10, so that the elastic member 43 can provide a locking force to the locking member 41, thereby facilitating the locking or unlocking between the locking member 41 and the vertical rod 30.
[0044] In addition, Figure 2 and Figure 3As shown, the inner partition 32 is provided with a plurality of vertically spaced locking holes 33 , and the locking member 41 is locked in any one of the locking holes 33 . The side of the inner partition 32 facing away from the slide groove is provided with ribs 34 corresponding to the plurality of locking holes 33 .
[0045] It can be understood that a plurality of locking holes 33 are provided on the inner partition 32, a portion of the locking holes 33 are evenly spaced along the middle of the length direction of the inner partition 32, and another portion of the locking holes 33 are arranged close to the bottom of the inner partition 32. The locking holes 33 on the inner partitions 32 on the left and right sides are relatively arranged, so as to facilitate the locking engagement of the locking member 41 and the locking holes 33. For example, when the locking member 41 is locked with the locking hole 33 in the middle of the inner partition 32, a cushion can be provided on the crossbar 10, so as to facilitate the user to sit on the support structure 100 of the table and chair. When the locking member 41 is locked, the crossbar 10 can be provided with a cushion. When locked with the locking hole 33 at the bottom of the inner partition 32, a footrest can be set on the cross bar 10 to facilitate users to step on the support structure 100 of the table and chair, thereby enriching the usage scenarios of the support structure 100 of the table and chair, and a convex rib 34 is set on the side of the inner partition 32 away from the slide groove, and the convex rib 34 is arranged opposite to the multiple locking holes 33, so that the convex rib 34 can enhance the structural strength of the locking hole 33, thereby enhancing the locking strength between the cross bar 10 and the vertical bar 30, thereby enhancing the stability and durability of the support structure 100 of the table and chair.
[0046] Alternatively, as Figure 1 As shown, the vertical rod 30 is an integrally formed aluminum alloy profile, and the sliding part 20 is a plastic part. The aluminum alloy material can ensure the structural strength of the vertical rod 30, thereby improving the stability and durability of the support structure 100 of the table and chair. The sliding part 20 made of plastic material can save material costs and also realize the lightweight design of the support structure 100 of the table and chair.
[0047] The table and chair according to the present invention includes: the support structure 100 of the table and chair of the above embodiment. By arranging a sliding member 20 at the end of the crossbar 10 and arranging an inner partition 32 within the outer rod body 31, the inner partition 32 and the outer rod body 31 together form a longitudinal slide groove, and the sliding member 20 can move within the slide groove. This arrangement enables the crossbar 10 to move relative to the vertical rod 30 in the longitudinal direction of the vertical rod 30, thereby limiting the position of the crossbar 10 according to the actual needs of the user, thereby enriching the use scenarios of the support structure 100 of the table and chair and improving the utilization rate of the support structure 100 of the table and chair.
