Base for display screen
This display screen turning apparatus (base for a display screen) includes a platelike base member so formed as to receive the load of a display body applied to a display screen support mechanism on a partial region and to warp in a direction opposite to the direction of deflection resulting from the load of the display body with a prescribed amount of warpage when not receiving the load of the display body, and the prescribed amount of warpage is so set that the surface of the base member is substantially flattened when the base member receives the load of the display body applied to the display screen support mechanism.
1. A display, comprising:
a display screen;
a support member supporting said display screen;
a substantially planar base member so formed as to receive a load of said display screen applied to said support member on a partial region thereof and to warp in a direction opposite to the direction of deflection resulting from the load of said display screen with a prescribed amount of warpage when not receiving the load of said display screen;
a plurality of first rubber legs provided under said region of said base member receiving the load of said display screen;
a plurality of rolling elements annularly arranged between said support member and said base member for receiving the load of said display screen through said support member; and
a holding member holding said plurality of rolling elements and having a cylindrical shape, wherein
said prescribed amount of warpage is so set that the surface of said base member is substantially flattened when said base member receives the load of said display screen applied to said support member, and
said first rubber legs are provided on a region of said base member directly below said plurality of rolling elements at an equiangular interval.
2. The display according to claim 1 , wherein
said base member is so formed that the maximum length in the anteroposterior direction of said display screen is smaller than the maximum length in the cross direction of said display screen, and
said base member is so formed as to warp along the anteroposterior direction of said display screen.
3. The display according to claim 2 , wherein
said base member has a substantially trapezoidal shape in plan view, and
said base member is so formed as to warp along a direction perpendicular to the upper side or the lower side of said trapezoidal shape in plan view.
4. The display according to claim 1 , further comprising second rubber legs provided under portions in the vicinity of four corners located outside said region of said base member receiving the load of said display screen.
5. The display according to claim 1 , further comprising a rotating shaft portion provided at the center of said base member to protrude toward said support member, for serving as the rotation center of said support member.
6. The display according to claim 5 , wherein
said support member is horizontally rotatable about said rotating shaft portion serving as the rotation center,
the base for a display screen further comprises a stop member for preventing said support member from slipping off said rotating shaft portion, and
a groove portion for mounting said stop member is provided on the outer peripheral surface of said rotating shaft portion in the vicinity of the upper end.
7. The display according to claim 1 , wherein
said base member is made of sheet metal.
8. A display, comprising:
a display screen;
a support member supporting said display screen;
a substantially planar base member receiving a load of said display screen applied to said support member on a partial region thereof;
a plurality of rolling elements annularly arranged between said support member and said base member for receiving the load of said display screen through said support member, a holding member holding said plurality of rolling elements and having a cylindrical shape, and a plurality of first rubber legs provided under a region of said base member corresponding to said rolling elements, wherein
said base member is so formed that the maximum length in the anteroposterior direction of said display screen is smaller than the maximum length in the cross direction of said display screen, and so formed as to warp in a direction opposite to the direction of deflection resulting from the load of said display screen with a prescribed amount of warpage when not receiving the load of said display screen,
said prescribed amount of warpage is so set that the surface of said base member is substantially flattened when said base member receives the load of said display screen applied to said support member, and
said first rubber legs are provided on said region of said base member corresponding to said rolling elements at an equiangular interval.
9. The display according to claim 8 , wherein
said base member has a substantially trapezoidal shape in plan view, and
said base member is so formed as to warp along a direction perpendicular to the upper side or the lower side of said trapezoidal shape in plan view.
10. The display according to claim 8 , further comprising second rubber legs provided under portions in the vicinity of four corners located outside said region of said base member receiving the load of said display screen.
11. The display according to claim 8 , further comprising a rotating shaft portion provided at the center of said base member to protrude toward said support member, for serving as the rotation center of said support member.
12. The display according to claim 11 , wherein
said support member is horizontally rotatable about said rotating shaft portion serving as the rotation center,
the display further comprises a stop member for preventing said support member from slipping off said rotating shaft portion, and
a groove portion for mounting said stop member, the groove portion being provided on the outer peripheral surface of said rotating shaft portion in the vicinity of the upper end.
13. The display according to claim 8 , wherein
said base member is made of sheet metal.
