Description

Technical Field

[0001] The utility model relates to a furniture component, in particular to a furniture metal foot. Background Art

[0002] 1. At present, some similar products are made of aluminum die-casting as a whole. The supporting foot rods (support claws / support foot rods / support bars) are solid. Aluminum must be of high density. The price of aluminum materials is higher every year, resulting in rising costs, high production costs for manufacturers, and low market competitiveness. In order to save costs, some businesses use some low-density aluminum or make the products thinner. When some people use chairs and tables, their bearing capacity is too heavy and they are deformed or broken.

[0003] 2. The supporting feet (support claws / support feet / support bars) of some similar products are made of steel bars / steel sheets / steel plates in one piece. The supporting feet (support claws / support feet / support bars) are solid. Steel is heavy and cannot be made too thick. If it is too thick or too large, it will be too bulky. If it is too thin, it will not achieve the required thickness structure and aesthetics.

[0004] 3. Now some similar products are made of plastic injection molding as a whole. The supporting feet (support claws / support feet / support bars) are solid. The plastic must be strong after molding. The price of plastic materials is higher every year, resulting in rising costs, high production costs for manufacturers, and low market competitiveness. In order to save costs, some businesses use some inferior plastics or second-hand refurbished plastics or make the products thinner, etc. When some people use chairs and tables, their bearing capacity is too heavy and they are deformed or broken.

DETAILED DESCRIPTION

[0022] A furniture metal foot, which is made of metal and is used for furniture chairs, furniture tables, furniture desks, furniture cabinets, etc., and is preferably used as a chair foot; the furniture metal foot is made of steel; it includes a center ring 1 and at least three supporting claws 2, and the center ring 1 and the supporting claws 2 are made of steel; the center ring 1 and the supporting claws 2 are made of the same material; the diameter of the center ring 1 is 4 cm to 8 cm, and the size is determined according to the size of the different furniture used; the length of the supporting claws 2 is 30 cm to 60 cm, and the length is determined according to the size of the different furniture used; a center axis hole 11 is opened in the middle of the center ring 1, and the diameter of the center axis hole 11 is 3.5 cm to 7 cm, and the size is determined according to the size of the different furniture used, and it is a through-hole type, and is used to install a support rod or a supporting axis core or a rotating axis core of a chair seat; the center axis hole 11 is arranged longitudinally, and the supporting claws 2 are arranged transversely relative to the center ring 1, and the supporting claws 2 are arranged in an inclined manner with a high root and a low tail, and the supporting claws 2 gradually become smaller from the root to the tail, which is more beautiful and good-looking, and at the same time, The support has good stability; the root of the support claw 2 is welded and fixedly connected to the outer wall of the center ring 1, and the support claws 2 are equidistantly distributed around the outer periphery of the center ring 1, and each support claw 2 is evenly stressed when it falls to the ground; the outer surfaces of the center ring and the support claws are covered with a plating layer or a spray coating for decoration and rust and corrosion prevention; the main technical improvements of this product are: the support claw 2 is a rectangular strip with good structural strength and better rectangular support; the support claw 2 is integrally stamped and bent to change the high cost of aluminum die-casting in the past. The current fine new process uses steel plates to make it, and it is stamped and formed with steel plate stamping equipment, which has low cost and high production efficiency; after the support claw 2 is stamped and formed, an axial hollow cavity 201 is formed inside, and the old aluminum die-casting cannot make a hollow structure. The old aluminum die-casting is solid after forming, and the amount of material used is large. The current fine new process steel plate stamping equipment stamping can reduce the amount of material required; the support claw 2 is a hollow metal shell, and the overall structure is hard and strong. The wall thickness of the support claw 2 is between 1.5 mm and 5 mm. The thicker the wall thickness, the better the strength, hardness and support force. The cost of steel is lower than that of aluminum, so the cost is much lower after the overall production. The support claw 2 of such a structure can be made thicker and more beautiful, and is suitable for a wide range of furniture, especially chairs and tables.

[0023] The supporting claw 2 includes a top wall 21, a left side wall 22, a right side wall 23, a left bottom bent flange 24, a right bottom bent flange 25, and a tail lower elbow cover 26. The end of the top wall 21 is integrally extended to connect the tail lower elbow cover 26. The left and right sides of the top wall 21 are integrally bent downward to connect the left side wall 22 and the right side wall 23. The bottom edge of the left side wall 22 is integrally bent inward to connect the left bottom bent flange 24. The bottom edge of the right side wall 23 is integrally bent inward to connect the right bottom bent flange 25. The top wall 21, the left side wall 22, the right side wall 23, the left bottom bent flange 24, and the right bottom bent flange 25 are bent and surrounded to form an axial hollow cavity 201. The top wall 21, the left side wall 22, the right side wall 23, the left bottom bent flange 24, and the right bottom bent flange 25 are coordinated to form a rectangular strip after multiple bending and surrounding. The top surface of the top wall 21 is a plane or a curved surface or an arched surface; the left side wall 22 and the right side wall 23 are planes; the left bottom bending flange 24 and the right bottom bending flange 25 are planes; the tail lower elbow cover 26 is a curved surface or an arched surface;

[0024] This is to further refine the specific structure of the supporting claw 2, forming a circumferential surround to achieve high strength, good hardness and good supporting force.

[0025] A gap 251 is formed between the left bottom bending flange 24 and the right bottom bending flange 25; the gap 251 between the left bottom bending flange 24 and the right bottom bending flange 25 has several welding connection points 27, which play a role in reinforcing the connection; because the left bottom bending flange 24 and the right bottom bending flange 25 cannot be in contact with each other for sealing after bending, a gap 251 is formed; of course, the entire gap 251 can also be welded and sealed.

[0026] A foot pad installation recess 28 is formed at the bottom of the lower elbow cover 26 to reserve space for installing furniture foot pads of different types.

[0027] The foot pad installation recess 28 is fixedly connected to the supporting foot pad assembly 3 by means of a screw assembly, welding, clamping, or the like.

[0028] The supporting foot pad assembly 3 includes a fastening connector 31 and an anti-skid rubber pad 32. The fastening connector 31 is made of metal and is welded and fixedly connected to the foot pad mounting recess 28. The shape of the fastening connector 31 is consistent with the shape of the foot pad mounting recess 28 and fits perfectly. The bottom of the fastening connector 31 is clamped or pierced or fixedly connected to the anti-skid rubber pad 32 by screws.

[0029] A fastening hole 311 is provided on the fastening connector 31 , and the anti-skid rubber pad 32 is connected and installed in the fastening hole 311 by means of screws or rubber heads thereof to form a fixed connection.

[0030] There are four supporting claws 2, which are equally spaced and distributed around the outer periphery of the central ring 1, that is, one claw is arranged every 90 degrees, so that the supporting forces on four sides are balanced and stable.

[0031] There are five supporting claws 2 , which are equally spaced and distributed around the outer periphery of the central ring 1 .

[0032] The number of supporting claws 2 is determined according to the different furniture used. Chairs and tables generally use four or five claws, while other small-sized furniture with low load-bearing capacity can use three claws. The three claws form a trident support, which is also a stable support.
