Description

Technical Field

[0001] The invention discloses a supporting foot with a reinforced structure, which is arranged at the bottom of furniture to provide furniture support and height adjustment. Prior Art

[0002] Support legs are commonly found on any furniture that needs to stand on the ground, such as cabinets and chairs. When furniture is equipped with multiple support legs, the weight of the body will be concentrated on each support leg, making the furniture stand firmly and raising the furniture at a lower cost.

[0003] In addition, during the early furniture manufacturing process, the floor was designed to be flat. Therefore, generally speaking, the length of the furniture support legs would be exactly the same. However, in reality, it is difficult for the floor of a home to be completely flat. There are many reasons for the unevenness of the floor, such as the thermal expansion and contraction caused by the large temperature difference throughout the year, the need for drainage in the area, and the need for a tilted design of the floor. Therefore, placing furniture on these uneven floors will cause the furniture to stand unstable and may shake.

[0004] To address this issue, furniture support legs are now designed to be height-adjustable. Currently, the most common height-adjustment mechanism for furniture support legs on the market utilizes a screw structure. However, this adjustment structure is not suitable for heavier furniture (e.g., large cabinets weighing over 100 kg). Furthermore, when adjusting the height of the support leg, the screw and joints are prone to cracking due to the weight.

[0005] In view of the above problems, it is necessary to improve the structural strength of the portion of the adjustable support foot used to engage the screw rod so that the adjustable support foot can adapt to heavier furniture. Summary of the Invention

[0006] The element used to connect the screw rods in the present invention is a middle connector, and the outer side of the middle connector is surrounded by a circle of annular reinforcing ribs that are flat on the top and inclined on the bottom. In addition to strengthening the structural strength of the middle connector, the annular reinforcing ribs can also use their structure to diagonally distribute the force of the screw lock on the middle connector. Therefore, the present invention can effectively strengthen the structural strength of the middle connector used to connect the screw rods. As a result, the present invention can adapt to heavier furniture than conventional products.

[0007] To achieve the above-mentioned objectives and effects, the present invention provides a support foot with a reinforced structure, which includes: a furniture connector; a base having a screw; and a middle connector including a first assembly portion, a second assembly portion, and an annular reinforcing rib. The annular reinforcing rib is located around the connection between the first assembly portion and the second assembly portion, and the thickness of the annular reinforcing rib gradually decreases from the inside to the outside. The annular reinforcing rib has a flat top surface and a lower inclined surface. The first assembly portion is assembled with the furniture connector, and the second assembly portion has a screw hole, in which the screw is screwed.

[0008] Furthermore, there is an angle between the flat top surface and the lower inclined surface, and the angle is 25 degrees to 35 degrees.

[0009] Furthermore, the second combination part has an appearance of a hexagonal column with six outer sides.

[0010] Furthermore, among the outer side surfaces of the second combination portion, the connection between adjacent outer side surfaces presents an arc-guiding state.

[0011] Furthermore, the furniture connector has a combination hole, the inner wall of the combination hole is provided with twelve grooves at intervals, the outer side surface of the first combination part is provided with twelve ribs at intervals, the first combination part is inserted into the combination hole, and each rib is limited to the corresponding groove in each groove.

[0012] Furthermore, the base includes a force-applying portion and a bottom plate portion, and the force-applying portion is connected between the screw and the bottom plate portion.

[0013] Furthermore, the thread of the screw is spaced apart by a plurality of concave segments, and the inner side of the screw has a reinforcing rib at a position corresponding to each screw.

[0014] Furthermore, the force-applying portion is hexagonal in shape.

[0015] Furthermore, the base has a plurality of triangular strengthening ribs, which are distributed in a ring shape at the connecting position between the bottom plate and the force-applying part. Simple diagram description

Implementation

[0017] For a more detailed understanding of the embodiments of the present invention, it may also be viewed in conjunction with the diagram, as presented in the first to sixth figures, the present invention is a support foot base with a reinforced structure, which includes: a furniture connector 1; 33 , the annular reinforcement rib 33 is located on the perimeter side where the first combination portion 31 joins the second combination portion 32 , the thickness of the annular reinforcement rib 33 is progressive from the inside to the outside, the annular reinforcement rib 33 has a flat top surface 331 , a lower inclined surface 332 , the second combination portion 32 has a screw hole 321 , the screw hole 23 screws 1 .

[0018] The foregoing are the main technical features of the main embodiment of the invention, which correspond to the contents of item 1 of the scope of the patent application in this case, and the purpose and embodiment of the invention can be detailed.

[0019] Continuing the foregoing further details of embodiments of the present invention, as presented in Figures I to VII, where the screw 21 is part of the base 2 and the furniture connector 1 is used to connect the bottom of the furniture 100 , and in the invention it is used to link the screw The element of 21 is a middle joint 3 , and the outer side of the middle joint 3 is surrounded by a circle of upper flat and downward slope (flat top surface 331 and lower inclined surface 332) annular reinforcing ribs 33 Its structural features The diagonally dispersed middle joint 3 bears the force of the screw 21 screw lock (the clamping angle θ1 between the flat top surface 331 and the lower inclined surface 332 is 25~35 degrees, where the effect is better when the clamping angle θ1 is 30 degrees, at this time the lower inclined surface 332 and the second combination part 32 of the clamping angle θ2 of about 120 degrees) so that the present invention does achieve the structural strength of the middle joint 3 reinforced for joining parts of the screw 21. In this way, the present invention is indeed novel and progressive compared to the knowledge that the product is indeed able to adapt to heavier weight furniture.

[0020] Furthermore, the second assembly portion 32 has an appearance of a hexagonal prism with six outer side surfaces 322, wherein the connection between adjacent outer side surfaces 322 of each of the second assembly portion 32 presents an arc-guided appearance. From a mechanical point of view, the forces on all sides of the regular hexagonal prism are relatively equal, and the structure has relatively excellent strength.

[0021] Furthermore, the furniture connector 1 has a combination hole 11, and the inner wall of the combination hole 11 is provided with twelve grooves 12 at intervals. The outer side surface of the first combination part 31 is provided with twelve ribs 311 at intervals. The first combination part 31 is inserted into the combination hole 11, and each rib 311 is limited to the corresponding groove 12 in each groove 12. The aforementioned number of ribs 311 and grooves 12 has a better combination degree.

[0022] Furthermore, the base 2 includes a force-applying portion 22 and a bottom plate portion 23. The force-applying portion 22 is connected between the screw 21 and the bottom plate portion 23. The force-applying portion 22 is hexagonal in shape, as shown in Figure 7. This structure enables the operator to use a common wrench 200 to operate the base rotation.

[0023] Furthermore, the threads of the screw rod 21 are spaced apart by a plurality of concave segments 211. A reinforcing rib 212 is provided on the inner side of the screw rod 21 at a position corresponding to each screw rod 21. The concave segments 211 prevent the screw rod 21 and the screw hole 321 from being too airtight when assembled. However, the concave segments 211 can reduce the structural strength. Therefore, adding reinforcing ribs 212 on the inner side of the corresponding positions can improve the structural strength.

[0024] Furthermore, the base 2 has a plurality of triangular strengthening ribs 24, which are distributed in a ring shape at the connection position between the bottom plate portion 23 and the force-applying portion 22 to strengthen the connection strength between the force-applying portion 22 and the bottom plate portion 23.
