Definitions

  • the present invention relates to a metallic knob and a method for making it.
  • a conventional metallic knob in accordance with the prior art shown in Fig. 9 can be attached to an article (not shown) such as a drawer, a cabinet, a wardrobe and the like and includes a body (50) made of a solid copper alloy containing a threaded bore (55) defined in the bottom thereof to secure the solid body (50) to the article.
  • a body (50) made of a solid copper alloy containing a threaded bore (55) defined in the bottom thereof to secure the solid body (50) to the article.
  • Making the body (50) out of a solid material increases the production cost.
  • the solid body (50) is made by turning it on a lathe such that it takes a great deal of time to make the solid body (50), thereby decreasing the productivity of the metallic knob.
  • a metallic knob comprising: a hollow base including a first end formed with a column and a second end formed with a bowl, the column containing a through bore defined in the bottom thereof; and a cap secured to the bowl of the hollow base.
  • a method for making a metallic knob comprising the steps of: (a) providing an elongated first metallic sheet; (b) forming a column on the first metallic sheet by punching; (c) forming a through bore in the bottom of the column by punching; (d) forming a bowl on the first metallic sheet by punching, the bowl extending from the column; (e) separating the bowl from the first metallic sheet by punching, thereby forming a hollow base which includes the column and the bowl; (f) providing an elongated second metallic sheet; (g) forming a dome on the second metallic sheet by punching; (h) separating the dome from the second metallic sheet by punching, thereby forming a cap; and (i) securing the cap to the bowl by riveting, thereby forming the metallic knob which includes the hollow base and the cap.
  • a metallic knob in accordance with the present invention can be adapted to fit to an article (not shown) such as a drawer, a cabinet, a wardrobe and the like, and comprises a hollow base (10) including a first end formed with a column (11) and a second end formed with a bowl (15), and a cap (20) secured to the bowl (15) of the hollow base (10) and including a dome (21).
  • an article such as a drawer, a cabinet, a wardrobe and the like, and comprises a hollow base (10) including a first end formed with a column (11) and a second end formed with a bowl (15), and a cap (20) secured to the bowl (15) of the hollow base (10) and including a dome (21).
  • the column (11) includes a concave (14) formed on the periphery thereof, and contains a through bore (12) defined in the bottom thereof and formed with an inner thread (120) to secure the column (11) to the article.
  • the column (11) further contains a plurality of through holes (13) defined in the bottom thereof.
  • the bowl (15) contains a plurality of through holes (16) defined in the periphery thereof and includes a lip (17) formed on the periphery thereof, and the cap (20) includes an engaging flange (22) formed on the periphery thereof and secured on the lip (17) of the bowl (15) by riveting.
  • a method is used to make the metallic knob in accordance with the present invention, and includes the steps described as follows.
  • an elongated first metallic sheet (10A) is fed through a plurality of molds (not shown) so as to be punched by means of a plurality of punch heads (not shown) each of which mate with one of the corresponding molds.
  • a column (11) is then formed on the first metallic sheet (10A) by punching.
  • a raw blank (11A) with a greater diameter and a shorter height than the column (11) is initially formed on the first metallic sheet (10A) so as to gradually form the column (11), thereby preventing the first metallic sheet (10A) from breaking due to excessive deformation.
  • a recess (122) is formed in the bottom of the column (11), and a through bore (12) is formed in the recess (122) by punching.
  • a plurality of through holes (13) are formed in the bottom of the column (11), and a plurality of through holes (16) are punched in the first metallic sheet (10A) so as to drain cooling water or lubricating oils required during the manufacturing process.
  • a lip (17) is formed on the periphery of the bowl (15), and the bowl (15) is then separated from the first metallic sheet (10A) by punching, thereby forming a hollow base (10) which includes the column (11) and the bowl (15).
  • a concave (14) is then formed on the periphery of the column (11) by a roll pressing process to enhance the aesthetic quality of the hollow base (10).
  • an elongated second metallic sheet (20A) is fed through a plurality of molds (not shown) so as to be punched by means of a plurality of punch heads (not shown) each of which mate with one of the corresponding molds.
  • a press seam (26) is formed on the second metallic sheet (20A) by punching to conform to the periphery of the cap (20).
  • a dome (21) is then formed on the second metallic sheet (20A), and is separated from the second metallic sheet (20A) by punching, thereby forming the cap (20).
  • An engaging flange (22) is formed on the periphery of the dome (21) by punching before the dome (21) is separated from the second metallic sheet (20A).
  • the cap (20) is secured to the bowl (15) by riveting the engaging flange (22) to the lip (17), thereby forming the metallic knob that includes the hollow base (10) and the cap (20).
  • An inner thread (120) is then formed in the inner periphery of the through bore (12).
  • the metallic knob that includes the hollow base (10) and the cap (20) is then machined by a surface treatment, thereby enhancing the aesthetic quality of the metallic knob.
  • the dome (21) of the cap (20) may have decorative patterns formed on it, thereby further enhancing the aesthetic quality of the metallic knob.
