Abstract
A lower end of one of two support members 80 is pivotally connected to a support wall 81 having a slant face 81A in a first keyboard unit 3 and an upper end is pivotally connected to one plate part of a hinge joint 92. A lower end of the other support member 80 is pivotally connected to a support wall 83 having a slant face 83A in a second keyboard unit 4 and an upper end is pivotally connected to the other plate part of the hinge joint 92. At the time when the first and second keyboard units 3 and 4 are fully opened in a horizontal position, the support members 80 are set up in a standing orientation tilting at an angle of 45° with the operating plane of a keyboard 1.
Claims9
A foldable keyboard including a first keyboard unit, a second keyboard unit, and a rotational connecting part provided between the first and second keyboard units, so that the first and second keyboard units are rotated about the connecting part to come apart from each other into an unfolded, horizontally arranged state for use of the keyboard, while the first and second keyboard units are rotated about the connecting part to come close to each other into a closed, folded state for nonuse of the keyboard, the keyboard including:
- a first support member having a first end and a second end, the first end being pivotally connected to a back wall of the first keyboard unit;
- a second support member having a first end and a second end, the first end being pivotally connected to a back wall of the second keyboard unit;
- wherein the second ends of the first and second support members are pivotally connected with each other, and the first and second support members are set up in a standing orientation in synchronization with the rotation of the first and second keyboard units in a direction which they come apart from each other.
A foldable keyboard including a first keyboard unit, a second keyboard unit, and a rotational connecting part provided between the first and second keyboard units, so that the first and second keyboard units are rotated about the connecting part to come apart from each other into an unfolded, horizontally arranged state for use of the keyboard, while the first and second keyboard units are rotated about the connecting part to come close to each other into a closed, folded state for nonuse of the keyboard, the keyboard including:
- a connector unit for connecting the keyboard to a portable device;
- a first connector storage part formed in the first keyboard unit;
- a second connector storage part formed in the second keyboard unit and for storing, in conjunction with the first connector storage part, the connector unit;
- a first support link which connects the first connector storage part to the connector unit;
- a second support link which connects the second connector storage part to the connector unit;
- wherein the connector unit is moved toward the rotational connecting part from the first and second connector storage parts in synchronization with rotation of the first and second keyboard units in a direction which they come apart from each other, and the connector unit is placed above the rotational connecting part in a substantial center of the keyboard when the first and second keyboard units are rotated into the horizontally arranged state.
