POP-UP APPARATUS
Embodiments generally relate to music devices. In one embodiment, an apparatus includes a first four-bar mechanism operably connected to a first user interface. The apparatus also includes a second four-bar mechanism operably connected to a second user interface. The apparatus also includes a third four-bar mechanism operably connected to the first and second four-bar mechanisms.
1 . An apparatus comprising:
a first four-bar mechanism operably connected to a first user interface;
a second four-bar mechanism operably connected to a second user interface; and
a third four-bar mechanism operably connected to the first and second four-bar mechanisms.
2 . The apparatus of claim 1 , wherein the third four-bar mechanism synchronizes movement of the first and second four-bar mechanisms.
3 . The apparatus of claim 1 , wherein at least two of the four-bar-mechanisms are four-bar parallelogram linkages.
4 . The apparatus of claim 1 , wherein at least one of the four-bar-mechanisms is a four-bar convex quadrilateral linkage.
5 . The apparatus of claim 1 , further comprising a base that functions as a support base for the apparatus.
6 . The apparatus of claim 1 , further comprising a base that functions as a common bar in each of the first mechanism, the second mechanism, and the third four-bar mechanism.
7 . The apparatus of claim 1 , wherein the first four-bar mechanism enables the first user interface to be positioned in a first plane.
8 . The apparatus of claim 1 , wherein the second four-bar mechanism enables the second user interface to be positioned in a second plane.
9 . The apparatus of claim 1 , wherein the first four-bar mechanism enables the first user interface to be positioned in a first plane, wherein the second four-bar mechanism enables the second user interface to be positioned in a second plane, and wherein the first plane is different from the second plane.
10 . An apparatus comprising:
a first four-bar mechanism operably connected to a first user interface, wherein the first four-bar mechanism enables the first user interface to be positioned in a first plane;
a second four-bar mechanism operably connected to a second user interface, wherein the second four-bar mechanism enables the second user interface to be positioned in a second plane; and
a third four-bar mechanism operably connected to the first and second four-bar mechanisms.
11 . The apparatus of claim 10 , wherein the third four-bar mechanism synchronizes movement of the first and second four-bar mechanisms.
12 . The apparatus of claim 10 , wherein at least two of the four-bar-mechanisms are four-bar parallelogram linkages.
13 . The apparatus of claim 10 , wherein at least one of the four-bar-mechanisms is a four-bar convex quadrilateral linkage.
14 . The apparatus of claim 10 , further comprising a base that functions as a support base for the apparatus.
15 . A method comprising:
providing a first four-bar mechanism operably connected to a first user interface;
providing a second four-bar mechanism operably connected to a second user interface; and
providing a third four-bar mechanism operably connected to the first and second four-bar mechanisms.
16 . The method of claim 15 , wherein the first four-bar mechanism enables the first user interface to be positioned in a first plane
17 . The method of claim 15 , wherein the second four-bar mechanism enables the second user interface to be positioned in a second plane
18 . The method of claim 15 , wherein the third four-bar mechanism synchronizes movement of the first and second four-bar mechanisms.
19 . The method of claim 15 , wherein at least two of the four-bar-mechanisms are four-bar parallelogram linkages.
20 . The method of claim 15 , wherein at least one of the four-bar-mechanisms is a four-bar convex quadrilateral linkage.
