Abstract
A safety hook includes a main body defining an inner space and an opening, a latch unit pivoted to the main body, an operable unit pivoted to the main body, and a safety lock unit. The latch unit is normally at a closed position for blocking the opening. When the operable unit is pressed, the safety lock unit is co-rotatable with the operable unit with respect to the main body from a locked position, where the safety lock unit abuts against the latch unit to retain the latch unit at the closed position, to an unlocked position, where the safety lock unit is removed from the latch unit to allow the latch unit to rotate from the closed position to an opened position allowing access into the inner space through the opening.
Claims14
A safety hook comprising:
- a main body that includes a base portion, an intermediate portion connected to said base portion, and a hook portion connected to said intermediate portion opposite to said base portion, curvedly extending from said intermediate portion toward said base portion, cooperating with said base portion and said intermediate to define an inner space, and cooperating with said base portion to define an opening in spatial communication with said inner space;
- a first pivot member that is disposed at said base portion of said main body;
- a latch unit that is pivoted to said base portion of said main body by said first pivot member, that is rotatable with respect to said base portion from a closed position, where said latch unit blocks said opening, to an opened position, where said latch unit allows access into said inner space through said opening, and that has an inner surface facing said intermediate portion;
- a second pivot member that is disposed at said intermediate portion of said main body;
- an operable unit that is pivoted to said intermediate portion of said main body by said second pivot member, and that includes a user-operable portion distant from said second pivot member;
- and
- a safety lock unit that is pivoted to said intermediate portion by said second pivot member, and that includes an abutting end portion capable of abutting against said inner surface of said latch unit;
- wherein, when said user-operable portion of said operable unit is pressed, said safety lock unit is co-rotatable with said operable unit with respect to said intermediate portion of said main body from a locked position, where said abutting end portion of said safety lock unit abuts against said inner surface of said latch unit so as to retain said latch unit at the closed position, to an unlocked position, where said abutting end portion of said safety lock unit is removed from said inner surface of said latch unit so as to allow said latch unit to pivot with respect to said base portion of said main body from the closed position to the opened position.
