Abstract
A hinge assembly has a tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface. A button member extends into the tubular member to undergo sliding movement in an axial direction along the longitudinal axis of the tubular member and to undergo rotational movement relative to the tubular member. A pin member is connected to the button member and extends into the slot of the tubular member to undergo movement therein during sliding and rotational movement of the button member relative to the tubular member. The button member is biased in a preselected direction of rotation relative to the tubular member by a first biasing member. The button member is biased in an axial direction by a second biasing member.
Claims27
A hinge assembly comprising:
- a tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface;
- a button member extending into the tubular member to undergo sliding movement in an axial direction along the longitudinal axis of the tubular member and to undergo rotational movement relative to the tubular member;
- a pin member connected to the button member and extending into the slot of the tubular member to undergo movement therein during sliding and rotational movement of the button member relative to the tubular member;
- a first biasing member for biasing the button member in a preselected direction of rotation relative to the tubular member;
- and a second biasing member for biasing the button member in the axial direction.
A hinge assembly comprising:
- a first tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface;
- a second tubular member extending into the first tubular member so that the first tubular member is capable of undergoing rotational movement relative to the second tubular member, the second tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface thereof;
- a button member extending into the second tubular member for undergoing sliding movement in an axial direction along the longitudinal axis of the second tubular member;
- a pin member connected to the button member and extending through the slot of the first tubular member and into the slot of the second tubular member for undergoing movement in each of the slots during rotational movement of the first tubular member and sliding movement of the button member;
- a first biasing member for biasing the first tubular member in a preselected direction of rotation relative to the second tubular member;
- and a second biasing member for biasing the button member in the axial direction.
A hinge assembly for rotationally mounting a rotational member to a body member, the hinge assembly comprising:
- a first tubular member to be secured to a rotational member, the first tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface;
- a second tubular member to be secured to a body member, the second tubular member extending into the first tubular member so that the first tubular member is capable of undergoing rotational movement relative to the second tubular member, the second tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface thereof;
- a button member extending into the second tubular member for undergoing sliding movement in an axial direction along the longitudinal axis of the second tubular member;
- a pin member connected to the button member and extending through the slot of the first tubular member and into the slot of the second tubular member for undergoing movement in each of the slots during rotational movement of the first tubular member and sliding movement of the button member;
- a first biasing member for biasing the first tubular member in a preselected direction of rotation relative to the second tubular member;
- and a second biasing member for biasing the button member in the axial direction.
In combination with a portable communication apparatus having a main body and a pair of strap members for mounting the main body to an arm of a user, a hinge assembly comprising:
- a pair of hinge units each for rotationally mounting respective ones of the strap members to the main body, each of the hinge units having a first tubular member connected to a respective one of the straps and having a slot formed in a peripheral surface thereof, a second tubular member connected to the main body and having a portion extending into the first tubular member so that the first tubular member is capable of undergoing rotational movement relative to the second tubular member, a button member having a portion extending into the second tubular member for undergoing sliding movement therein in an axial direction along a longitudinal axis of the second tubular member, a pin member connected to the button member and extending through the slot of the first tubular member for undergoing movement in the slot during rotational movement of the first tubular member and sliding movement of the button member so that the respective strap member undergoes movement between an open state and a closed state relative to the main body, a first biasing member for biasing the first tubular member in a preselected direction of rotation relative to the second tubular member, and a second biasing member for biasing the button member in the axial direction.
