Abstract
An engagement fitting comprises a hook that is integrally formed from a metal rod member. The rod member is bent into a generally U-shaped configuration. Bases then can be bent at approximately right angles at base ends of a pair of legs of the generally U-shaped hook. The bases extend to opposite sides from one another across a plane that is generally defined by the U-shaped configuration. The base is formed at least partially flat and can be provided with attachments such that the engagement fitting can be mounted on other members.
Claims21
An engagement fitting comprising:
- a hook having a generally U-shaped configuration, the hook comprising a first leg, a second leg, and an engagement pestle extending between the first and second legs;
- a first base member extending at an approximately right angle from a base end of the first leg, the first base member comprising a first arm and a first attachment portion at an end of the first arm, the first attachment portion comprising at least one mounting hole having a central axis, at least a portion of the first base member being generally flat;
- a second base member extending at an approximately right angle from a base end of the second leg;
- the second base member comprising a second arm and a second attachment portion at an end of the second arm, the second attachment portion comprising at least one mounting hole having a central axis, at least a portion of the second base member being generally flat;
- and
- an imaginary plane defined by the central axes of the mounting holes, the imaginary plane bisecting the engagement pestle and a longitudinal axis of the engagement pestle extending substantially normal to the imaginary plane.
An engagement fitting comprising:
- a hook comprising a first leg, a second leg, and an engagement pestle extending between the first and second legs;
- a first base member extending from a base end of the first leg, the first base member comprising at least one mounting hole having a central axis;
- a second base member extending from a base end of the second leg;
- the second base member comprising at least one mounting hole having a central axis;
- and
- an imaginary plane defined by the central axes of the mounting holes, the imaginary plane bisecting the engagement pestle and a longitudinal axis of the engagement pestle extending substantially normal to the imaginary plane.
An engagement fitting comprising a hook and a base that are integrally formed with a single metal rod member, the hook having a generally U-shaped configuration comprising a first and a second leg, the base having first and second base portions, each extending at an approximately right angle from a respective base end of the legs, the generally U-shaped hook being positioned between the base portions, each base portion having an engagement end and a generally flat attachment portion positioned between the engagement end and the respective base end of the legs, each attachment portion comprising a mounting hole, each mounting hole comprising a central axis and an imaginary plane that is defined by the central axes substantially bisecting the U-shaped hook, the engagement end of the first base portion configured to receive the base end of the second leg and the engagement end of the second base portion configured to receive the base end of the first leg.
