  • Patent number: 7219807
    Abstract: A mold assembly for making a tool bracket of a tool suspension device includes a lower part and an upper part. The upper part is mounted on the lower part and includes a common mold and multiple interchangeable molds. The common mold has multiple through cavities to mold the tool brackets simultaneously. Each through cavity has a primary flat molding surface. The interchangeable molds are demountably mounted in common mold and have upper cavities aligned respectively with the through cavities. Each of the upper cavities has a bottom, a marking portion formed on the bottom and a secondary flat molding surface flush with the primary flat molding surface of the aligned through cavity. Consequently, the tool bracket molded by the mold assembly has a front product indicator and an offset parting line to make the front of the tool bracket clean.

  • Patent number: 7198158
    Abstract: A tool suspension device has a bracket and multiple holders. The bracket has an upper rail, a lower rail and two mounting holes. Each holder slidably clamps onto the bracket and has a clamp and a support arm. The clamp has an upper groove and a lower groove that clamp respectively on the upper and lower rail. The support arm is formed on and extends out from the clamp and has two sides, a distal end, optional jaws and an optional lip. The jaw on one holder faces a jaw on an adjacent holder to hold a tool between the jaws. The lip is formed on the distal end of the arm to keep a hanging tool from slipping off the arm.
