Description

TECHNICAL FIELD

[0001] The utility model relates to a universal foot pad and belongs to the technical field of folding chair foot pads. BACKGROUND

[0002] Folding chairs are a type of chair that can be folded up for storage or transport. They are typically made of lightweight materials and have a foldable design that allows them to be easily collapsed when not in use, saving space and making them convenient to carry.

[0003] Currently, folding chairs have foot pads at the bottom of their support legs. These foot pads prevent the folding chairs from sliding during use, providing good anti-slip and floor protection. Common folding chair foot pads are directly fixed to the bottom of the support legs, which means that the angle between the support surface and the ground is fixed (usually parallel to ensure maximum contact area between the support surface and the ground). When the angle of the folding chair is adjusted, such foot pads cannot adjust the angle accordingly, which can cause an angle between the support surface and the ground, making it difficult for the foot pad to provide sufficient support. This can cause discomfort and fatigue in the legs of the user, affecting their comfort and the effectiveness of the folding chair. SUMMARY

[0004] To solve the above-mentioned problems in the prior art, the utility model provides a universal foot pad.

[0005] The technical solution of the utility model is as follows:

The bottom of the connecting part is movably connected to the top of the support part. The bottom of the support part is used to contact the ground. The top of the connecting part is used to connect to the support leg of a folding chair.

[0007] The top of the support part is internally provided with a connecting groove with an arc-shaped cross-section. The bottom of the connecting part is provided with a connecting block with a spherical structure. The diameter of the connecting groove is adapted to the diameter of the connecting block. The connecting block is movably embedded in the connecting groove.

[0008] The central angle of the arc-shaped cross-section of the connecting groove is greater than 180 degrees.

[0009] The support part and the connecting block are made of elastic material.

[0010] The bottom of the connecting block is internally provided with a deformation groove.

[0011] The limiting part is arranged at the position where the connecting block is connected with the connecting part, and a gap is left between the bottom of the limiting part and the top of the supporting part.

[0012] The top of the connecting part is further provided with a plurality of matching parts, and each matching part is arranged in close contact with the inner wall of the supporting leg of the folding chair.

[0013] The utility model has the advantages of the following beneficial effects:

[0014] The supporting part and the connecting part are movably connected, specifically, a connecting groove is formed in the supporting part, a connecting block is arranged on the connecting part, and the connecting block is movably embedded in the connecting groove, so that the supporting part can move relative to the connecting part, and the supporting part can rotate by 360 degrees on the connecting part.

[0020] The utility model will be described in detail in combination with the drawings and specific embodiments.

[0021] Embodiment: please refer to Figs. 1-3 The utility model provides a universal foot pad, which comprises a supporting part 1 and a connecting part 2, the supporting part 1 is arranged below the connecting part 2. The bottom of the connecting part 2 is movably connected with the top of the supporting part 1, the bottom of the supporting part 1 is used for contacting the ground, and the top of the connecting part 2 is used for connecting with the supporting leg of the folding chair.

[0022] Through the foregoing arrangement, the movable connection of the support part 1 and the connecting part 2 enables the support part 1 to be adjusted in angle on the connecting part 2. When the angle of the folding chair is adjusted, the posture of the support part 1 on the connecting part 2 can be adjusted by adjusting the included angle between the support part 1 and the connecting part 2, so that the support part 1 can be adjusted to be still parallel between the bottom and the ground. Thus, when the angle of the folding chair is adjusted, the universal foot pad can still provide sufficient support by adjusting the posture of the support part 1. Compared with the prior art, the universal foot pad has the advantages of good support effect, and ensures the user's body feeling and the use effect of the folding chair. After the included angle between the support part 1 and the connecting part 2 is adjusted, the weight of the user and the weight of the folding chair can both generate pressure on the connecting part 2, and the generated pressure can fix the angle between the connecting part 2 and the support part 1, so that the support part 1 and the connecting part 2 will not shake, thereby ensuring the stability of the universal foot pad during use.

[0023] In the embodiment, the cross section of the support part 1 is arranged in a structure with a large bottom and a small top, so as to provide sufficient contact area with the ground when the subsequent folding chair support leg stands on the ground, thereby ensuring the standing effect. The top of the support part 1 is inwardly provided with a connecting groove 3 arranged in an arc-shaped structure, the bottom of the connecting part 2 is provided with a connecting block 4 arranged in a spherical structure, the diameter of the connecting groove 3 is arranged in correspondence with the diameter of the connecting block 4, and the connecting block 4 is arranged in an active manner in the connecting groove 3. Through the arrangement of the connecting block 4 and the connecting groove 3, when the angle of the support part 1 on the connecting part 2 is adjusted, the connecting block 4 can rotate in the connecting groove 3 in correspondence, so as to adapt to the adjustment work, and the arc-shaped connecting groove 3 and the spherical connecting block 4 can also enable the support part 1 to rotate 360° on the connecting part 2, so as to realize universal adjustment, thereby greatly improving the applicability of the foot pad.

[0024] In order to ensure the connection stability of the connecting block 4 embedded in the connecting groove 3, in the embodiment, the central angle of the arc-shaped structure of the cross section of the connecting groove 3 is arranged to be greater than 180°, and preferably the central angle is between 200° and 250°, so as to ensure that the connecting block 4 is not easily dropped out of the connecting groove 3.

[0025] In order to enable the connecting block 4 to be smoothly and actively embedded in the connecting groove 3, in the embodiment, the support part 1 and the connecting block 4 are both made of elastic material, such as common rubber material or plastic material. When the connecting block 4 is embedded in the connecting groove 3, the connecting block 4 and the support part 1 can be deformed in correspondence to adapt to the embedding work.

[0026] In order to enable the connecting block 4 to be more easily and movably embedded in the connecting groove 3, in the embodiment, a deformation groove 5 is further formed in the bottom of the connecting block 4, and the deformation groove 5 can enable the connecting block 4 to have a larger deformation space, so that the connecting block 4 can be more easily and movably embedded in the connecting groove 3.

[0027] In order to avoid the connecting block 4 from falling off from the connecting groove 3 during use, in the embodiment, a limiting portion 6 is further arranged on the connecting block 4, and the limiting portion 6 is arranged at the position where the connecting block 4 is connected with the connecting portion 2, and a gap is left between the bottom of the limiting portion 6 and the top of the supporting portion 1, and the specific size of the gap can be set according to actual conditions. Through the foregoing arrangement, the gap is reserved to provide a space for the relative movement between the supporting portion 1 and the connecting portion 2, so as to ensure that the supporting portion 1 and the connecting portion 2 can perform the required adjustment work. When the top of the supporting portion 1 and the bottom of the limiting portion 6 are in contact, at this time, the supporting portion 1 cannot continue to rotate towards the limiting portion 6, and the limiting portion 6 can limit the rotation angle of the supporting portion 1, that is, limit the included angle between the supporting portion 1 and the connecting portion 2, so as to avoid the phenomenon that the connecting block 4 is pressed and falls off from the connecting groove 3 during the downward movement of the folding chair. In the embodiment, the limiting portion 6 is arranged in a semi-cylindrical structure, so as to strengthen the structural strength between the connecting block 4 and the connecting portion 2 under the premise of providing the limiting function, so as to avoid the phenomenon that the connecting block 4 is broken from the connecting portion 2. At the same time, the semi-cylindrical structure can also leave space for the fingers of the subsequent operator to enter, so as to facilitate the operator to perform the disassembly work of the supporting portion 1 and the connecting portion 2. In actual use, the specific shape of the limiting portion 6 can also be set according to actual conditions.

[0028] In the embodiment, the top of the connecting portion 2 is in a cylindrical structure, and a plurality of cooperating portions 7 are further arranged on the top of the connecting portion 2, and the cooperating portions 7 are uniformly distributed on the top of the connecting portion 2. The cooperating portions 7 are also made of elastic materials, such as common rubber materials, plastic materials, etc. Each cooperating portion 7 is tightly arranged with the inner wall of the folding chair supporting leg. Through the tight arrangement of the cooperating portions 7 with the inner wall of the folding chair supporting leg, the top of the connecting portion 2 can be installed on the folding chair supporting leg by using the principle of friction.
