FIG. 2 is a front perspective view of a mounting bracket (100) according to an exemplary embodiment of the present disclosure, and FIGS. 3a and 3b are rear perspective views of the mounting bracket (100) according to an exemplary embodiment of the present disclosure.

[0050] Referring to FIGS. 1 to 3b together, the sprinkler support assembly (10) of the present disclosure may include a T-bar (Tb), a support bar (Sb), a mounting bracket (100) configured to mount a sprinkler reducer (Sk) on the support bar (Sb), and a support bracket (200) configured to support the support bar (Sb) on the T-bar (Tb).

[0051] The T-bar (Tb) has a cross-section in the shape of the alphabet T and can support the support bracket (200). For example, a portion of the outer surface of the T-bar (Tb) can be compressed by the support bracket (200).

[0052] The T-bar (Tb) may include a bottom portion (Tb_1), an extension portion (Tb_2) extending vertically from the bottom portion (Tb1), and a head portion (Tb_3) protruding from a side of the extension portion (Tb_2).

[0053] The support bar (Sb) may be a bar extending in a first direction (e.g., parallel to the ground) to support the sprinkler reducer (Sk). For example, the cross-section of the support bar (Sb) may be provided in a rectangular shape, but is not limited thereto.

[0054] The mounting bracket (100) may be a bracket configured to mount a sprinkler reducer (Sk) on a support bar (Sb) extending in a first direction. The mounting bracket (100) may include a first base (110), a second base (120), a fixed lever (130), an elastic hanger (140), a lever coupling axis (150), a lever fixing axis (160), a base rotation axis (170), etc.

[0055] The first base (110) may extend in a second direction perpendicular to the first direction. The second direction may be parallel to the ground but perpendicular to the first direction. In addition, the first base (110) may pass through the support bar (Sb) through the first support hole (110H).

[0056] The second base (120) can extend in the second direction. In addition, the second base (120) can pass through the support bar (Sb) through the second support hole (120H). The second base (120) can be rotatably coupled to a portion of the first base (110). That is, the second base (120) can be configured to rotate relative to the first base (110). The first base (110) and the second base (120) can surround at least a portion of the sprinkler reducer (Sk).

[0057] The first base (110) may include a first base wall (111) extending in a second direction and having a first support hole (110H) passing through the support bar (Sb), and a plurality of first fixed walls (113, 115) bent from the first base wall (111) to surround a portion of the sprinkler reducer (Sk).

[0058] In an exemplary embodiment, the plurality of first fixed walls (113, 115) may include a first upper fixed wall (113) bent from the upper portion of the first base wall (111), and a first lower fixed wall (115) bent from the lower portion of the first base wall (111). For example, the first upper fixed wall (113) and the first lower fixed wall (115) may face each other so as to be parallel to each other.

[0059] Additionally, the second base (120) may include a second base wall (121) extending in the second direction and having a second support hole (120H) passing through the support bar (Sb), and a plurality of second fixed walls (123, 125) that are bent from the second base wall (121) so as to overlap at least a portion of the plurality of first fixed walls (113, 115) and surround a portion of the sprinkler reducer (Sk).

[0060] In an exemplary embodiment, the plurality of second fixed walls (123, 125) may include a second upper fixed wall (123) that is bent from the upper portion of the second base wall (121) and overlaps a portion of the first upper fixed wall (113), and a second lower fixed wall (125) that is bent from the lower portion of the second base wall (121) and overlaps a portion of the first lower fixed wall (115). For example, the first lower fixed wall (115) and the second lower fixed wall (125) may face each other so as to be parallel to each other.

[0061] In an exemplary embodiment, the first base (110) can surround at least a portion of the second base (120). Specifically, the first upper fixed wall (113) of the first base (110) can surround a portion of the second upper fixed wall (123) of the second base (120). Additionally, the first lower fixed wall (115) of the first base (110) can surround a portion of the second lower fixed wall (125) of the second base (115). Accordingly, the first base (110) and the second base (120) can be rigidly rotationally coupled.

[0062] In an exemplary embodiment, a first separation distance between a first upper fixed wall (113) and a first lower fixed wall (115) of a first base (110) may be greater than a second separation distance between a second upper fixed wall (123) and a second lower fixed wall (125) of a second base (120).

[0063] A base rotation axis (170) is provided at the rear of the support bar (Sb) so as to pass through the overlapping portions of the first base (110) and the second base (120) to couple the first base (110) and the second base (120). Accordingly, the second base (120) can rotate relative to the first base (110) through the base rotation axis (170). That is, the first base (110) and the second base (120) can rotate around the base rotation axis (170) to come into contact with or be separated from the side of the sprinkler reducer (Sk).

[0064] The lever coupling shaft (150) may be a coupling shaft provided to the first base (110) for coupling between the fixed lever (130) and the first base (110). In an exemplary embodiment, the lever coupling shaft (150) may be interposed between a plurality of first fixed walls (113, 115) of the first base (110).

[0065] The lever fixing shaft (160) may be a fixing shaft provided to the second base (120) to fix the fixing lever (130) to the second base (120). In an exemplary embodiment, the lever fixing shaft (160) may be interposed between a plurality of second fixing walls (123, 125) of the second base (120).

[0066] An elastic hanger (140) may be provided inside the second base (120) and configured to engage with the fixed teeth (131p) of the fixed lever (130) when the first base (110) and the second base (120) are coupled.

[0067] In an exemplary embodiment, the elastic hanger (140) may be an elastic hooking member interposed between the second upper fixed wall (123) and the second lower fixed wall (125) of the second base (120) and engaging with the fixed teeth (131p). For example, the elastic hanger (140) may be a rod provided in a clip shape, but the shape of the elastic hanger (140) is not limited to that described above.

[0068] The fixed lever (130) can be coupled and disengaged from the first base (110) by rotational driving from a portion of the second base (120). In an exemplary embodiment, the fixed lever (130) can be coupled with the lever coupling shaft (150) by rotation in a first rotational direction from a portion of the second base (120). In this case, the fixed lever (130) can surround the front of the sprinkler reducer (Sk).

[0069] Additionally, in an exemplary embodiment, the fixed lever (130) may be separated from the lever engagement shaft (150) by rotating in a second rotational direction opposite to the first rotational direction from a portion of the second base (120). In this case, the fixed lever (130) may not cover the front of the sprinkler reducer (Sk).

[0070] The fixed lever (130) may include a handle (131) configured to rotate from a lever fixing shaft (160) and having a fixed tooth (131p) that engages with an elastic hanger (140) on one side. In addition, the fixed lever (130) may include a locking wall (133) having a hook (133p) that rotates from the handle (131) and engages with a lever engaging shaft (150). For example, the locking wall (133) may be configured to rotate from the handle (131) by a locking rotating shaft (135) that rotates the locking wall (133) and the handle (131).

[0071] In an exemplary embodiment, when the handle (131) rotates in a direction closer to the support bar (Sb) while the hook (133p) of the locking wall (133) is engaged with the lever engaging shaft (150), the fixed teeth (131p) provided on the inner portion of the handle (131) may engage with the elastic hanger (140). As the fixed teeth (131p) engage with the elastic hanger (140), the rotation of the handle (131) by the locking rotation shaft (135) may be restricted. The state in which the hook (133p) of the locking wall (133) is engaged with the lever engaging shaft (150) and the fixed teeth (131p) are engaged with the elastic hanger (140) may be defined as a locked state of the mounting bracket (100).

[0072] In an exemplary embodiment, when the handle (131) is rotated away from the support bar (Sb) in the locked state of the mounting bracket (100), the elastic hanger (140) is pushed by the fixed teeth (131p), so that the engagement between the elastic hanger (140) and the fixed teeth (131p) can be released. As the engagement between the fixed teeth (131p) and the elastic hanger (140) is released, the rotation of the handle (131) by the locking rotation axis (135) can be freely performed. Accordingly, the engagement between the hook (133p) of the locking wall (133) and the lever engagement axis (150) can also be easily released. A state in which the engagement between the hook (133p) of the locking wall (133) and the lever coupling shaft (150) is released and the engagement between the fixed teeth (131p) and the elastic hanger (140) is released can be defined as an open state of the mounting bracket (100).

[0073] In an exemplary embodiment, in the locked state of the mounting bracket (100), the side of the sprinkler reducer (Sk) can be pressed by the first base (110) and the second base (120). In addition, in the locked state of the mounting bracket (100), the rear of the sprinkler reducer (Sk) can be pressed by the front of the support bar (Sb).

[0074] In an exemplary embodiment, the front of the sprinkler reducer (Sk) may be covered by the locking wall (133) in the locked state of the mounting bracket (100). At this time, the locking wall (133) may be spaced apart from the front of the sprinkler reducer (Sk) without making contact with it.

[0075] In the locked state of the mounting bracket (100), the first base (110) and the second base (120) can be in close contact with the side of the sprinkler reducer (Sk), and the support bar (Sb) can be in close contact with the rear of the sprinkler reducer (Sk). Accordingly, the mounting bracket (100) can be firmly mounted on the support bar (Sb).

[0076] In addition, the locking wall (133) can be spaced apart from the front of the sprinkler reducer (Sk), so that an empty space can be secured in front of the sprinkler reducer (Sk), and the sprinkler reducer (Sk) can not directly receive the pressing force of the fixing lever (130). Accordingly, physical damage to the sprinkler reducer (Sk) and the fixing lever (130) can be reduced.

[0077] In the open state of the mounting bracket (100), the first base (110) and the second base (120) can release the side seal of the sprinkler reducer (Sk). Accordingly, the size of the hole (Sk_H) surrounding the sprinkler reducer (Sk) increases, so that the sprinkler reducer (Sk) can be easily separated from the mounting bracket (100).

[0078] In an exemplary embodiment, the first base wall (111) may include a first upper flange (111a) supporting the upper surface of the support bar (Sb), a first lower flange (111b) supporting the lower surface of the support bar (Sb), and a first side flange (111c) supporting the rear surface of the support bar (Sb).

[0079] Specifically, the first upper flange (111a) is a flange provided on the upper side of the first base wall (111) and can support the upper surface of the support bar (Sb), the first lower flange (111b) is a flange provided on the lower side of the first base wall (111) and can support the lower surface of the support bar (Sb), and the first side flange (111c) is a flange provided on the side side of the first base wall (111) and can support the side surface of the support bar (Sb). Since the first base wall (111) can include the above-described flanges, the first base wall (111) can firmly support the support bar (Sb).

[0080] Additionally, the second base wall (121) may include a second upper flange (121a) supporting the upper surface of the support bar (Sb), a second lower flange (121b) supporting the lower surface of the support bar (Sb), and a second side flange (121c) supporting the rear surface of the support bar (Sb).

[0081] Specifically, the second upper flange (121a) is a flange provided on the upper side of the second base wall (121) and can support the upper surface of the support bar (Sb), the second lower flange (121b) is a flange provided on the lower side of the second base wall (121) and can support the lower surface of the support bar (Sb), and the second side flange (121c) is a flange provided on the side side of the second base wall (121) and can support the side surface of the support bar (Sb). Since the second base wall (121) can include the aforementioned flanges, the second base wall (121) can firmly support the support bar (Sb).

[0082] FIGS. 4A to 4D are drawings showing a process of joining a mounting bracket (100) and a sprinkler reducer (Sk) according to an exemplary embodiment of the present disclosure.

[0083] Referring to FIG. 4a, the first base (110) can pass through the support bar (Sb) through the first support hole (110H), and the second base (120) can pass through the support bar (Sb) through the second support hole (120H). In addition, for easy entry and exit of the sprinkler reducer (Sk), the first base (110) and the second base (120) can rotate by the base rotation axis (170) to increase the size of the hole (Sk_H) surrounding the sprinkler reducer (Sk).

[0084] Referring to FIG. 4b, when the sprinkler reducer (Sk) is placed in the space between the first base (110) and the second base (120), the first base (110) and the second base (120) can rotate by the base rotation axis (170) to surround at least a portion of the side and front of the sprinkler reducer (Sk).

[0085] Referring to Fig. 4c, after the first base (110) and the second base (120) surround the side of the sprinkler reducer (Sk), the hook (133p) of the locking wall (133) can be rotated from the locking rotation axis (135) to engage with the lever engagement axis (150). At this time, the fixed teeth (131p) provided on the inner portion of the handle (131) may not be engaged with the elastic hanger (140).

[0086] Referring to FIG. 4d, after the hook (133p) of the locking wall (133) is engaged with the lever engaging shaft (150), the handle (131) can be rotated by the user in a direction closer to the support bar (Sb). At this time, the fixed teeth (131p) provided on the inner portion of the handle (131) can be engaged with the elastic hanger (140). As the fixed teeth (131p) are engaged with the elastic hanger (140), the rotation of the handle (131) by the locking rotation shaft (135) can be restricted. The state in which the hook (133p) of the locking wall (133) is engaged with the lever engaging shaft (150) and the fixed teeth (131p) are engaged with the elastic hanger (140) can be defined as a locked state of the mounting bracket (100).

[0087] In the locked state of the mounting bracket (100), the first base (110) and the second base (120) can be in close contact with at least a portion of the side and front of the sprinkler reducer (Sk), and the support bar (Sb) can be in close contact with the rear of the sprinkler reducer (Sk). Accordingly, the mounting bracket (100) can be firmly mounted on the support bar (Sb).

[0088] In addition, when the mounting bracket (100) is locked, the locking wall (133) can be spaced apart from the front portion of the sprinkler reducer (Sk) without contacting it, so that an empty space can be secured in front of the sprinkler reducer (Sk). Accordingly, the sprinkler reducer (Sk) can not directly receive the force provided by the fixing lever (130). In other words, physical damage due to contact between the sprinkler reducer (Sk) and the fixing lever (130) can be prevented.

[0089] FIG. 5 is a side view of a mounting bracket (100) in a locked state according to an exemplary embodiment of the present disclosure.

[0090] Referring to FIG. 5, the first base wall (111) may include a first upper flange (111a) supporting the upper surface of the support bar (Sb), a first lower flange (111b) supporting the lower surface of the support bar (Sb), and a first side flange (111c) supporting the rear surface of the support bar (Sb).

[0091] Additionally, the second base wall (121) may include a second upper flange (121a) supporting the upper surface of the support bar (Sb), a second lower flange (121b) supporting the lower surface of the support bar (Sb), and a second side flange (121c) supporting the rear surface of the support bar (Sb).

[0092] The first base wall (111) and the second base wall (121) can include the aforementioned flange, so that the first base wall (111) and the second base wall (121) can firmly support the support bar (Sb). In addition, since the first base wall (111) and the second base wall (121) include the aforementioned flange, the height (i.e., the vertical length) of the first base wall (111) and the second base wall (121) can relatively increase. Accordingly, the durability of the first base (110) and the second base (120) can be improved.

[0093] In addition, in the locked state of the bracket (100), the first base (110) and the second base (120) can be in close contact with at least a portion of the side and front of the sprinkler reducer (Sk), and the support bar (Sb) can be in close contact with the rear of the sprinkler reducer (Sk). Accordingly, the mounting bracket (100) can be firmly mounted on the support bar (Sb).

[0094] In addition, the locking wall (133) can be spaced apart from the front of the sprinkler reducer (Sk), so that an empty space can be secured in front of the sprinkler reducer (Sk), and the sprinkler reducer (Sk) can not directly receive the pressing force of the fixing lever (130).

[0095] In an exemplary embodiment, the sprinkler reducer (Sk) may not be forced in all four directions (e.g., forward, backward, left, and right), but may be forced in only three directions (e.g., backward, left, and right). In this situation, a free space may be secured in front of the sprinkler reducer (Sk), so that physical damage to the sprinkler reducer (Sk) may be reduced. In addition, since the sprinkler reducer (Sk) and the fixed lever (130) do not directly contact each other, physical damage to the fixed lever (130) may also be reduced.

[0096] FIG. 6 is a perspective view of a mounting bracket (100a) according to another exemplary embodiment of the present disclosure.

[0097] Among the technical concepts of the mounting bracket (100a) of Fig. 6, the overlapping content with the mounting bracket (100) described with reference to Figs. 1 to 5 will be omitted and the differences will be mainly explained.

[0098] Referring to FIG. 6, the mounting bracket (100a) of the present disclosure may include a stopper (195). The stopper (195) of the present disclosure may be provided on the second upper fixed wall (123) of the second base (120).

[0099] In an exemplary embodiment, the stopper (195) may be provided in the form of a protrusion protruding from the upper surface of the second upper fixed wall (123). In addition, the stopper (195) may provide a restriction on the rotation of the first base (110). Specifically, when the first base (110) rotates in a direction that increases the size of the hole surrounding the sprinkler reducer (Sk) (i.e., in a direction away from the second base (120), the stopper (195) may not provide a restriction on the rotation of the first base (110).

[0100] Conversely, when the first base (110) rotates in a direction that reduces the size of the hole surrounding the sprinkler reducer (Sk) (i.e., moves closer to the second base (120)), the stopper (195) can provide a restriction on the rotation of the first base (110).

[0101] In an exemplary embodiment, the stopper (195) may be provided in a cylindrical shape, but the shape is not limited to the above-described shape. In addition, the level of the upper surface of the stopper (195) may be provided at a level lower than the level of the first upper fixed wall (113) of the first base (110). However, the present invention is not limited thereto, and the level of the upper surface of the stopper (195) may be substantially the same as the level of the first upper fixed wall (113) of the first base (110).

[0102] The mounting bracket (100a) of the present disclosure may include a stopper (195), so that the size of the hole (Sk_H) surrounding the sprinkler reducer (Sk) can be secured to a specific size or larger. Accordingly, the attachment of the sprinkler reducer (Sk) using the mounting bracket (100a) of the present disclosure may be facilitated.

[0103] Additionally, the mounting bracket (100a) of the present disclosure may include a spring structure (197) that surrounds the base rotation axis (170). In an exemplary embodiment, the central portion of the spring structure (197) may be provided in a coil shape to surround the base rotation axis (170).

[0104] Additionally, one side (197a) of the spring structure (197) can be coupled to the first upper fixed wall (113) of the first base (110), and the other side (197b) opposite to the one side (197a) can be coupled to the second lower fixed wall (125) of the second base (120).

[0105] When installing a sprinkler reducer (Sk), it may be important to finely adjust the combined height of the sprinkler reducer (Sk). However, when the hook (133p) of the locking wall (133) is combined with the lever combination shaft (150), the sprinkler reducer (Sk) and the mounting bracket (100a) are firmly combined, making it difficult to finely adjust the combined height of the sprinkler reducer (Sk).

[0106] The mounting bracket (100a) of the present disclosure may include a spring structure (197), so that even when the hook (133p) of the locking wall (133) of the present disclosure is not coupled with the locking rotation axis (135), the mounting bracket (100a) can be auxiliaryly pressed against the side of the sprinkler reducer (Sk) by the elasticity of the spring structure (197).

[0107] In this case, the worker can easily control the size of the hole (Sk_H) surrounding the sprinkler reducer (Sk) by using the force of the worker's hand that is greater than the elastic force provided by the spring structure (197). Accordingly, the combined height of the sprinkler reducer (Sk) can be finely adjusted.

[0108] In an exemplary embodiment, one side (197a) of the spring structure (197) may extend from a central portion surrounding the base rotation axis (170) and be coupled to a first upper fixed wall (113). The first upper fixed wall (113) may have a first spring coupling groove for receiving one side (197a) of the spring structure (197).

[0109] In an exemplary embodiment, the other side (197b) of the spring structure (197) may extend from a central portion surrounding the base rotation axis (170) and be coupled to a second lower fixed wall (125). The second lower fixed wall (125) may have a second spring coupling groove for receiving the other side (197b) of the spring structure (197). FIG. 7 is a perspective view of a support bracket (200) coupled with a T-bar (Tb) and a support bar (Sb) according to an exemplary embodiment of the present disclosure. FIG. 8 is a perspective view of a support bracket (200) not coupled with a T-bar (Tb) and a support bar (Sb) according to an exemplary embodiment of the present disclosure. FIG. 9 is a side view of a support bracket (200) according to an exemplary embodiment of the present disclosure. FIG. 10 is a bottom view of a support bracket (200) according to an exemplary embodiment of the present disclosure. Additionally, FIG. 11 is an enlarged view of a portion of a support bracket (200) combined with a T-bar (Tb) according to an exemplary embodiment of the present disclosure.

[0110] Referring to FIG. 1 and FIGS. 7 to 11 together, the support bracket (200) of the present disclosure may be a bracket that supports an edge portion of a support bar (Sb) that is placed on a T-bar (Tb) and is coupled to a sprinkler reducer (Sk).

[0111] The support bracket (200) may include a support frame (210) that supports one side of the support bar (Sb), a plurality of lower support protrusions (243, 253) that protrude from the inside of the support frame (210) and support an extension portion (Tb_2) of the T-bar (Tb), a plurality of upper support protrusions (223, 233) that protrude from the inside of the support frame (210) and support an upper surface of the head portion (Tb_3) of the T-bar (Tb), and a plurality of compression protrusions (263, 264) that protrude from the inside of the support frame (210) and support an upper surface of the head portion (Tb_3) of the T-bar (Tb).

[0112] The support frame (210) of the present disclosure may include a first support wall (211) passing through a support bar (Sb), a second support wall (213) facing the first support wall (211) and passing through the support bar (Sb), and a connecting wall (215) that is bent from the first support wall (211) and the second support wall (213) to connect the first support wall (211) and the second support wall (213).

[0113] In an exemplary embodiment, the first support wall (211) may be one wall of the support frame (210) that is relatively close to the sprinkler reducer (Sk), and the second support wall (213) may be another wall of the support frame (210) that is relatively far from the sprinkler reducer (Sk).

[0114] Additionally, the first support wall (211) and the second support wall (213) may face each other in parallel, and the first support wall (211) and the second support wall (213) may extend in the direction in which the sprinkler reducer (Sk) extends.

[0115] The first lower support protrusion (253) may be a protrusion that protrudes obliquely from the inner surface of the first support wall (211) and whose protrusion length increases as it goes upward. In addition, the first lower support protrusion (253) may press an extension portion (Tb_2) provided below a head portion (Tb_3) of a T-bar (Tb).

[0116] In an exemplary embodiment, the protruding length of the first lower support protrusion (253) can increase as it goes upward, so that the first lower support protrusion (253) can easily induce insertion of the T-bar (Tb) while preventing the T-bar (Tb) from coming off after insertion.

[0117] In an exemplary embodiment, the first lower support protrusion (253) may be provided in one piece. In addition, the first lower support protrusion (253) may extend in a direction parallel to the direction in which the T-bar (Tb) extends. When the first lower support protrusion (253) is viewed from a side view, the first lower support protrusion (253) may be provided in a trapezoidal shape with an inclined surface. In addition, the first lower support protrusion (253) may also be provided in a triangular shape.

[0118] The second lower support protrusion (243) may be a protrusion that protrudes obliquely from the inner surface of the second support wall (213) and whose protrusion length increases as it goes upward. In addition, the second lower support protrusion (243) may press the extension portion (Tb_2) provided below the head portion (Tb_3) of the T-bar (Tb) together with the first lower support protrusion (253).

[0119] In an exemplary embodiment, the protruding length of the second lower support protrusion (243) can increase as it goes upward, so that the second lower support protrusion (243) can easily induce insertion of the T-bar (Tb) while preventing the T-bar (Tb) from coming off after insertion.

[0120] In an exemplary embodiment, the second lower support protrusion (243) may be provided in one piece. In addition, the second lower support protrusion (243) may extend in a direction parallel to the direction in which the T-bar (Tb) extends. When the second lower support protrusion (243) is viewed from a side view, the second lower support protrusion (243) may be provided in a trapezoidal shape with an inclined surface. In addition, the second lower support protrusion (243) may be provided in a triangular shape.

[0121] In an exemplary embodiment, when the support bracket (200) is viewed from a planar perspective, the first lower support protrusion (253) and the second lower support protrusion (243) can be arranged symmetrically. Since the first lower support protrusion (253) and the second lower support protrusion (243) can be arranged symmetrically, the first lower support protrusion (253) and the second lower support protrusion (243) can symmetrically press the extension portion (Tb_2) of the T-bar (Tb).

[0122] The first upper support protrusion (233) may be a protrusion that protrudes obliquely from the inner surface of the first support wall (211) and whose protrusion length decreases as it goes upward. In addition, the first upper support protrusion (233) may be in close contact with the upper surface of the head portion (Tb_3) of the T-bar (Tb). That is, the first upper support protrusion (233) may function as a stopper that restricts the movement of the T-bar (Tb).

[0123] In an exemplary embodiment, the horizontal cross-sectional area of ​​the first upper support protrusion (233) may increase as it goes downward, so that the contact area between the upper surface of the head portion (Tb_3) of the T-bar (Tb) and the first upper support protrusion (233) may increase.

[0124] In an exemplary embodiment, the first upper support protrusion (233) may be provided in multiple pieces. For example, the first upper support protrusion (233) may be provided in two pieces. Additionally, the first upper support protrusion (233) may be provided in a trapezoidal shape with an inclined surface.

[0125] The second upper support protrusion (223) may be a protrusion that protrudes obliquely from the inner surface of the second support wall (213) and whose protrusion length decreases as it goes upward. In addition, the second upper support protrusion (223) may be in close contact with the upper surface of the head portion (Tb_3) of the T-bar (Tb). That is, the second upper support protrusion (223) may function as a stopper that restricts the movement of the T-bar (Tb).

[0126] In an exemplary embodiment, the horizontal cross-sectional area of ​​the second upper support protrusion (223) may increase as it goes downward, so that the contact area between the upper surface of the head portion (Tb_3) of the T-bar (Tb) and the second upper support protrusion (223) may increase.

[0127] In an exemplary embodiment, the second upper support protrusion (223) may be provided in multiple pieces. For example, the second upper support protrusion (223) may be provided in two pieces. Additionally, the second upper support protrusion (223) may be provided in a trapezoidal shape with an inclined surface.

[0128] In an exemplary embodiment, when the support bracket (200) is viewed from a planar perspective, the first upper support protrusion (233) and the second upper support protrusion (223) may be arranged in a zig-zag shape. That is, when the support bracket (200) is viewed from a planar perspective, the first upper support protrusion (233) and the second upper support protrusion (223) may not overlap.

[0129] In an exemplary embodiment, the first upper support protrusion (233) and the second upper support protrusion (223) can be arranged in a zig-zag manner, so that the first upper support protrusion (233) and the second upper support protrusion (223) can come into contact with the upper surface of the head portion (Tb_3) of the T-bar (Tb) over a relatively wide area.

[0130] In addition, since the first upper support protrusion (233) and the second upper support protrusion (223) may not spatially overlap on the upper side of the T-bar (Tb), the distance between the first support wall (211) of the support bracket (200) and the second support wall (213) may be easily adjusted by the distance adjustment screw (Sc_a).

[0131] In addition, since the first upper support protrusion (233) and the second upper support protrusion (223) may not spatially overlap on the upper side of the T-bar (Tb), the protrusion lengths of the first upper support protrusion (233) and the second upper support protrusion (223) may be provided to be greater than the protrusion lengths of the first lower support protrusion (253) and the second lower support protrusion (243).

[0132] In an exemplary embodiment, the first support wall (211) and the second support wall (213) may have a first hole (Sb_H1) for receiving a support bar (Sb). In addition, the first support wall (211) and the second support wall (213) may have a second hole (Sb_H2) provided at a lower portion of the first hole (Sb_H1) for receiving the support bar (Sb).

[0133] The first support wall (211) and the second support wall (213) can have a first hole (Sb_H1) and a second hole (Sb_H2), so that the support bracket (200) of the present disclosure can selectively support the support bar (Sb) at different heights.

[0134] In an exemplary embodiment, a portion of the outer surface of the first support wall (211) that overlaps with the first upper support protrusion (233) may have a first upper support groove (233G). In addition, a portion of the outer surface of the first support wall (211) that overlaps with the first lower support protrusion (253) may have a first lower support groove (253G).

[0135] Additionally, a portion of the outer surface of the second support wall (213) that overlaps with the second upper support protrusion (223) may have a second upper support groove (223G). Additionally, a portion of the outer surface of the second support wall (213) that overlaps with the second lower support protrusion (243) may have a second lower support groove (243G).

[0136] The support bracket (200) of the present disclosure can have the first upper support groove (233G), the second lower support groove (223G), the first lower support groove (253G), and the second lower support groove (243G) described above, so that the weight of the support bracket (200) can be reduced and the ease of gripping of the support bracket (200) by a user can be improved.

[0137] In an exemplary embodiment, the first compression protrusion (264) may protrude from the inner surface of the first support wall (211) and may compression the side surface of the head portion (Tb_3) of the T-bar (Tb). In addition, two first compression protrusions (264) may be provided at the edge of the first support wall (211). However, the number and position of the first compression protrusions (264) are not limited to those described above.

[0138] Additionally, the first compression protrusion (264) may be positioned between the first upper support protrusion (233) and the first lower support protrusion (253). In an exemplary embodiment, the first compression protrusion (264) may be provided so that the cross-sectional area in the vertical direction is the same.

[0139] In an exemplary embodiment, the second compression protrusion (263) may protrude from the inner surface of the second support wall (213) to compression the side surface of the head portion (Tb_3) of the T-bar (Tb). In addition, two second compression protrusions (263) may be provided at the edge of the second support wall (213). However, the number and position of the second compression protrusions (263) are not limited to those described above.

[0140] Additionally, the second compression protrusion (263) may be positioned between the second upper support protrusion (223) and the second lower support protrusion (243). In an exemplary embodiment, the second compression protrusion (263) may be provided so that the cross-sectional area in the vertical direction is the same.

[0141] In an exemplary embodiment, when the support bracket (200) is viewed from a planar perspective, the first compression protrusion (264) and the second compression protrusion (263) can be arranged symmetrically. Since the first compression protrusion (264) and the second compression protrusion (263) can be arranged symmetrically, the first compression protrusion (264) and the second compression protrusion (263) can symmetrically press the side surface of the head portion (Tb_3) of the T-bar (Tb).

[0142] The support bracket (200) of the present disclosure may include a first lower support protrusion (253) and a second lower support protrusion (243), a first upper support protrusion (233) and a second upper support protrusion (223), a first compression protrusion (264) and a second compression protrusion (263), so that the upper, lower, and side portions of the head portion (Tb_3) of the T-bar (Tb) can be firmly supported by the support bracket (200).

[0143] In an exemplary embodiment, the support bracket (200) may have a distance adjusting screw hole that accommodates a distance adjusting screw (Sc_a) that adjusts a distance between the first support wall (211) and the second support wall (213). For example, the distance adjusting screw hole may be provided between two first upper support protrusions (233) of the first support wall (211) and between two second upper support protrusions (223) of the second support wall (213).

[0144] In an exemplary embodiment, the support bracket (200) may have a fixing screw hole that receives a T-bar fixing screw (Sc_b) that passes through the first support wall (211), the T-bar (Tb), and the second support wall (213) to fix the T-bar (Tb) to the support bracket (200). The fixing screw hole may be provided below the distance adjusting screw hole described above.

[0145] In an exemplary embodiment, the support bracket (200) may have a support bar coupling screw hole provided in the connecting wall (215) and accommodating a support bar coupling screw (Sc_c) that couples the upper surface of the connecting wall (215) and the support bar (Sb).

[0146] In an exemplary embodiment, the support bracket (200) may include a protruding support wall (273, 274) that protrudes vertically from at least one of the first support wall (211) and the second support wall (213) to support at least a portion of the support bar (Sb). For example, the protruding support walls (273, 274) may include a first protruding support wall (273) provided in the first support wall (211) defining a first hole (Sb_H1) through which the support bar (Sb) passes, and a second protruding support wall (274) provided in the second support wall (213) defining a second hole (Sb_H2) through which the support bar (Sb) passes. In addition, the protruding support walls (273, 274) may have a coupling screw hole (273H, 274H) for screw coupling with the support bar. For example, the first protruding support wall (273) may provide a screw hole through which a screw (Sc_d) for fixing the first protruding support wall (273) and the support bar (Sb) may pass.

While specific terminology has been used to describe embodiments herein, it is intended solely to illustrate the technical concept of the present disclosure and is not intended to limit the scope of the present disclosure as defined in the claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present disclosure should be determined by the technical concept of the appended claims.
