[0028] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0029] Such as Figures 1 to 7As shown in the figure, the utility model provides a trapezoidal furniture foot, which includes an integrally formed base 1. The base 1 is arc-shaped, and a face cover 2 is covered on the base 1. Specifically, the base 1 includes a first cavity 105 with an upward opening. A lower edge 201 is provided on the bottom surface of the face cover 2. When the face cover 2 is covered on the base 1, the lower edge 201 is embedded into the first cavity 105, with a compact structure. A number of first bearing points are provided on the face cover 2, and a number of second bearing points are provided on the base 1. Moreover, the virtual connection line of the number of second bearing points encloses an area larger than the area enclosed by the virtual connection line of the number of first bearing points. First of all, the main bearing component is the integrally formed base 1, so its pressure-bearing capacity is better and the support strength is higher. In addition, the stress area at the upper and lower ends of the base 1 is different. When the end with a larger stress area (that is, the end with the second bearing points) faces upward and is connected to the furniture, it helps to increase the contact area with the furniture and enhance the supporting effect on the furniture.

[0030] The first bearing points are located on the same horizontal plane to form the surface of the face cover 2, and the second bearing points are located on the same horizontal plane to form the surface of the base 1. The surface of the face cover 2 and the surface of the base 1 are parallel to each other. That is, when applied in this embodiment, the first bearing points are located on the same horizontal plane to form the surface of the face cover 2, and this surface is in contact with the ground. The second bearing points are located on the same horizontal plane to form the surface of the base 1, and this surface is connected to the furniture or the component connected to the furniture. Thus, the stress area between the base 1 and the furniture or the component connected to the furniture is large, and the supporting effect is good.

[0031] As one of the structures, the first bearing points can be the upward convex upper surface of the face cover 2, and the second bearing points can be the downward convex lower surface of the base 1. As long as the area enclosed by the virtual connection line of the number of second bearing points is larger than the area enclosed by the virtual connection line of the number of first bearing points, a good supporting effect can be achieved.

[0032] The base 1 includes an outer side surface 101, a first side surface 102, a second side surface 103 and an inner side surface 104. The outer side surface 101 is inclined from top to bottom. The inclined shape also enhances the aesthetic appearance of the furniture foot. The angle θ between the outer side surface 101 and the vertical line is 15 - 25°. In this embodiment, the angle θ between the outer side surface 101 and the vertical line is 20°. Through actual application tests, the 20° angle enables the base 1 to have a good support strength while meeting the requirement of having an inclined streamline appearance. It also includes a edge wrapping, which is wrapped around the side surface of the base 1 to further enhance the aesthetic property. The inner side surface 104 is provided with a first slot 1041 and a second slot 1042 for the ends of the edge wrapping to end.

[0033] When installing the edge wrap, the middle part of the edge wrap fits on the outer side surface 101. The two ends of the edge wrap have right-angled folding hooks. One side of the edge wrap surrounds the first side surface 102 and the folding hook at the end is inserted into the first slot 1041. The other side of the edge wrap surrounds the second side surface 103 and the folding hook at the end is inserted into the second slot 1042. Then, the face cover 2 can be covered on the base 1; a sofa foot disclosed in the publication number CN205682849U is formed by splicing two components of the same size up and down. When installing the edge wrap, the edge wrap needs to correspond to the two components up and down to be compacted and installed; while in the furniture foot of the present application, only the edge wrap needs to be wrapped and installed on the base 1 and then the face cover 2 is covered and pressed tightly, which is convenient for installation.

[0034] Avoidance grooves 2011 are provided at the positions corresponding to the first slot 1041 and the second slot 1042 on the lower edge 201. The avoidance grooves 2011 are beneficial for making way for the upper end of the edge wrap and do not affect the normal installation of the edge wrap.

[0035] The face cover 2 is provided with a first connection hole 2012 and a positioning post 2013 corresponding to and located below the first connection hole 2012. The base 1 is provided with a second connection hole 106 and a positioning cylinder 107 corresponding to and located above the second connection hole 106. The positioning cylinder 107 is located in the first cavity 105; both the positioning post 2013 and the positioning cylinder 107 are hollow and are used in a corresponding and matching manner. The first connection hole 2012 and the second connection hole 106 are communicatively arranged through the hollow positions of the positioning post 2013 and the positioning cylinder 107; when the face cover 2 is covered on the base 1, the positioning post 2013 will be inserted into the positioning cylinder 107 to enhance the fixing effect between the two; the first connection hole 2012, the second connection hole 106, the positioning post 2013, and the positioning cylinder 107 are all arranged in a penetrating manner, so that a connecting screw is driven in from the penetrating position to fixedly connect the furniture foot to the furniture or a component connected to the furniture.

[0036] The surface of the base 1 away from the face cover 2 extends horizontally outward and is recessed to form a channel 108 for positioning and installing the edge wrap, which helps the edge wrap to be closely and fixedly installed on the base 1 along the channel 108; the channel 108 is non-closed, and the four peripheral edges of the face cover 2 protrude from the upper end of the base 1. When the edge wrap is closely wrapped on the base 1 along the channel 108, and then the face cover 2 is covered and pressed on the upper-end frayed edge of the edge wrap, the edge wrap can be restricted and fixed between the base 1 and the face cover 2.

[0037] The base 1 further includes a second cavity 109. There is a partition 110 between the first cavity 105 and the second cavity 109. The partition 110 is perpendicular to the lower surface of the base 1. The base 1 is integrally formed by injection molding. When injecting, a first mold is placed at the position corresponding to the first cavity 105, and a second mold is placed at the position corresponding to the second cavity 109. After injection molding, the first mold and the second mold need to be demolded. The perpendicular setting of the partition 110 helps the first mold and the second mold to be pulled out straightly from the upper end and the lower end of the base 1 respectively for demolding.

[0038] Figure 8 This is another first embodiment of the furniture foot described in the present invention. In this embodiment, the corresponding second cavity 109 is filled, and only the concave grid shape near the lower bottom surface of the base 1 is retained. Since the second cavity 109 is basically filled into a solid, the weight of this kind of furniture foot will be heavier than that of the furniture foot with the second cavity 109, but the bearing capacity will be stronger.

[0039] Figure 9 This is another second embodiment of the furniture foot described in the present invention. In this embodiment, the shape of the base 1 is different. The base 1 is in a straight shape to suit the support of different parts of the furniture.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
