Description

Technical Field

[0001] The present invention relates to the technical field of supporting feet, and in particular to a supporting foot with an adjustment mechanism. Prior Art

[0002] When purchasing new furniture, there are often many factors to consider. Height, width, and depth are all important factors that require advance measurement and assessment. However, some floors may sag or tilt due to factors such as climate and load. Furniture of a single height, however, will not receive evenly distributed loads due to varying floor levels, making it unstable, tilted, or even untenable.

[0003] Therefore, support legs are commonly found on furniture that needs to stand on the ground, such as cabinets and chairs. Installing support legs on furniture compensates for any differences in floor level, distributing the weight of the furniture across the support legs and ensuring a stable stand. However, conventional support leg height adjustment devices utilize circular force-applying elements, requiring the use of pliers or other tools to rotate the circular force-applying elements. When the support legs are installed on large furniture such as cabinets and closets, where the space between the bottom of the furniture and the ground is limited, the pliers can easily slip during rotation, making operation difficult.

[0004] Therefore, based on the above description, relevant industry players need to reconsider how to solve and improve the above problems. Therefore, the inventors have invested considerable time in researching related knowledge, comparing the pros and cons of various options, and conducting research and development of related products. After numerous experiments and tests, they have finally introduced a "support foot with an adjustment mechanism" that improves the above shortcomings and meets the needs of the public. Summary of the Invention

[0005] The main purpose of the present invention is to adjust the shape of the force-applying portion of the support foot to a polygonal shape, making it easier for the user to operate; this improves the defect of the force-applying portion of the support foot mentioned in the conventional technology that cannot be properly rotated.

[0006] In order to achieve the above-mentioned effects and improve the deficiencies of the conventional technology, the present invention provides a support foot with an adjustment mechanism, which includes: a connecting member, which has a connecting plate and a positioning groove, the positioning groove is located below the connecting plate, and the positioning groove is connected to the connecting plate; a sleeve member, which has a clamping portion and a sleeve portion, the clamping portion is connected to the sleeve portion, and the clamping portion is movably inserted into the positioning groove of the connecting member; a pivot member, which has a stud, a force-applying portion, and a support plate, the stud is movably screwed into the sleeve portion of the sleeve member, and the two ends of the force-applying portion are respectively connected to the stud and the support plate, the force-applying portion is polygonal, and the inner wall surface of the stud has a plurality of first reinforcing ribs, and the peripheral side of the force-applying portion connected to the support plate has a plurality of second reinforcing ribs from the force-applying portion to the outside.

[0007] According to the technical features defined above for the present invention, its advantage lies in that by adjusting the shape of the force-applying portion of the support foot to a polygonal shape, not only can it be operated using a more common wrench without the need to purchase additional special hand tools, but it can also increase the force-applying points, allowing the user to rotate and adjust conveniently and easily without slipping. This overall further improves the operational problems of conventional technologies, avoiding operational difficulties and the increased costs or labor associated with the use of special tools. This demonstrates that the present invention is indeed practical and progressive, and is worthy of promotion in the industry. Simple diagram description

[0009] In order to understand the implementation of the present invention in more detail, the features and functions of the embodiments of the present invention are described in detail with reference to the drawings. Please refer to Figures 1 to 7, which show a support foot A with an adjustment mechanism of the present invention, comprising: a connecting member 1 having a connecting plate 11 and a positioning groove 12, the positioning groove 12 being located below the connecting plate 11 and connected to the connecting plate 11; a sleeve member 2 having a clamping portion 21 and a sleeve portion 22, the clamping portion 21 being connected to the sleeve portion 22, the clamping portion 21 being movably inserted into the positioning groove 12 of the connecting member 1; a pivot The pivoting member 3 has a stud 32, a force-applying portion 33, and a support plate 34. The stud 32 is movably screwed to the sleeve portion 22 of the sleeve member 2. The two ends of the force-applying portion 33 are respectively connected to the stud 32 and the support plate 34. The force-applying portion 33 is polygonal, and the inner wall surface of the stud 32 has a plurality of first reinforcing ribs 324. The peripheral side of the force-applying portion 33 connected to the support plate 34 has a plurality of second reinforcing ribs 341 extending outward from the force-applying portion 33.

[0010] During assembly, the connecting piece 11 of the connecting member 1 is locked to the bottom end of the furniture with the positioning groove 12 of the connecting member 1 facing downward. Then, the locking portion 21 of the sleeve member 2 is inserted into the positioning groove 12 of the connecting member 1. After the insertion and fixation, the stud 32 of the pivot member 3 is aligned with the sleeve portion 22 of the sleeve member 2 and screwed into the sleeve portion 22. The assembly is completed by connecting the support plate 34 to the ground, as shown in the second and seventh figures.

[0011] To adjust the height of the support foot A, the user simply prepares a wrench B, aligns the opening of the wrench B with the force-applying portion 33 of the pivot member 3, and after engaging the wrench B with the force-applying portion 33, rotates the force-applying portion 33 left or right to adjust the length of the stud 32 inserted into the sleeve portion 22, thereby adjusting the overall height of the support foot A. The force-applying portion 33 is polygonal (hexagonal in this embodiment). This polygonal shape increases the engagement points with the wrench B, and the single diameter of the wrench B makes it less likely for the wrench B to slip out of the force-applying portion 33 when the user rotates it, allowing for intuitive operation, as shown in FIG7 .

[0012] In addition, the support foot A needs to be strong enough to bear the entire weight of the furniture, or to avoid collapse due to factors such as the placement of heavy objects or accidental collisions. Therefore, in addition to relying on the support of the support foot A body, the inner wall surface of the stud 32 and the peripheral side of the force-applying portion 33 connected to the support plate 34 are respectively provided with first reinforcing ribs 324 and second reinforcing ribs 341. When the support foot A bears the weight of the furniture, the weight can be distributed by the first reinforcing ribs 324 and the second reinforcing ribs 341, thereby reinforcing the load-bearing force, as shown in Figures 1, 2, 3, 4, 5, and 6.

[0013] Based on the above description, other technical features and structural features of the present invention will be further described. The connector 1 further has a plurality of reinforcing blocks 13. The connecting piece 11 has a plurality of positioning holes 111. The reinforcing blocks 13 are spaced apart and surround the outer wall of the positioning groove 12. The positioning holes 111 and the reinforcing blocks 13 are staggered. The positioning holes 111 provide the user with a position for installing the support foot A on the bottom of the furniture. Then, through the action of the reinforcing blocks 13, the force borne by the first reinforcing ribs 324 and the second reinforcing ribs 341 is reinforced and dispersed, as shown in Figures 1, 2, 3, 4, and 7.

[0014] When the clamping portion 21 of the sleeve member 2 is inserted into the positioning groove 12 of the connecting member 1, in order to ensure that the clamping portion 21 and the positioning groove 12 are firmly inserted to avoid collapse due to uneven force, the inner wall of the slot opening of the positioning groove 12 is surrounded by a plurality of positioning paths 122, and the outer wall surface of the clamping portion 21 of the sleeve member 2 is surrounded by a plurality of positioning ribs 211. When the clamping portion 21 is inserted into the positioning groove 12, each positioning path 122 corresponds to each positioning rib 211, and the sleeve member 2 and the connecting member 1 cannot rotate, as shown in the second figure.

[0015] In addition, the pivot member 3 has an internal space 31, which passes through the support plate 34 and the force-applying portion 33. The top surface of the stud 32 has an air hole 321, which communicates with the internal space 31. The outer surface of the stud 32 of the pivot member 3 has a plurality of concave tooth sections 322 and a plurality of screw tooth sections 323. The concave tooth sections 322 and the screw tooth sections 323 are staggered. The outer surface of the stud 32 has a position corresponding to each first reinforcing rib 324. The recessed tooth sections 322 are provided. When the support foot A is adjusted, the air in the internal space 31 is compressed. The air is discharged from the internal space 31 through the air holes 321 and then smoothly discharged along the gaps between the recessed tooth sections 322 and the inner walls of the sleeve portions 22. This prevents the screw thread sections 323 from being completely sealed against the inner walls of the sleeve portions 22, making it difficult to rotate and adjust the pivot member 3 within the sleeve portion 22, as shown in the second and third figures.

[0016] Since the support legs A are mostly installed on the legs of furniture, the distance between the legs makes it difficult for the user to quickly and accurately measure the height of each support leg A to be consistent. Therefore, a numerical notch 325 is provided in each recessed tooth section 322. The numerical notch 325 provides the user with a measurement reference, allowing the user to more conveniently adjust the required height to ensure that the height of each support leg A is consistent, as shown in the second, third, and fourth figures.

[0017] Furthermore, to prevent the support foot A from sliding due to a wet or overly smooth floor, the support plate 34 has an anti-slip protrusion 342. The anti-slip protrusion 342 is located on the side of the support plate 34 opposite to the force-applying portion 33. By increasing the contact area between the anti-slip protrusion 342 and the floor, friction is generated between the two, thereby achieving an anti-slip effect, as shown in the second and sixth figures.

[0018] In summary, the "support foot adjustment mechanism" of the present invention is indeed fully in line with the needs of industrial development in terms of practicality and cost-effectiveness. The disclosed structural creation also has an unprecedented innovative structure, so its "novelty" should be unquestionable. Moreover, the present invention can improve the effectiveness of conventional structures and is therefore "progressive". It fully complies with the provisions of the Patent Law of the People's Republic of my country regarding the application requirements for invention patents. Therefore, a patent application has been filed in accordance with the law, and the Office is cordially requested to review and approve it as soon as possible.
