Patent number: 7722003Abstract: Spiral springs (20) pressing a lift member (30) in an upward direction is arranged so that wound-up portions (20b) thereof move up and down along lift paths (13a, 13b) according as the lift member (30) moves up and down. In each lift path (13a, 13b) is provided a push-fit portion (40) of which a width is narrower than an outer diameter of the wound-up portion (20b) of the spiral spring (20), and in which according as the lift member (30) is lowered, the wound-up portion (20b) is fitted in such a manner that the wound-up portion becomes radially compressed. Accordingly, a cost-efficient and universally applicable display elevation adjusting apparatus can be provided which can make the operation feeling at the time of raising adjustment constant and can attain adjustment to suit the preference.Type: GrantFiled: October 29, 2004Date of Patent: May 25, 2010Assignees: Murakami Corporation, NEC Display Solutions, Ltd.Inventors: Takashi Ishizaki, Kenichi Hirasawa

Patent number: 6966532Abstract: A movable part 10 of a display orientation adjustment apparatus H is attached to a rear surface of a display, and pivotably supported by a base 20, and its pivotal motion is restricted by a stopper 50 within a permissible range. If the movable part 10 is pivoted beyond the restricted range by a pivoting force of a predetermined magnitude or greater, the stopper 50 is released. Therefore, even if the display is pivoted inadvertently beyond the permissible range of the pivotal motion, breakage of components thereof would never take place, and its normal state of use can easily be restored.Type: GrantFiled: January 26, 2004Date of Patent: November 22, 2005Assignees: Murakami Corporation, NEC-Mitsubishi Electric Visual Systems CorporationInventors: Takashi Ishizaki, Kenichi Hirasawa

Patent number: 6874738Abstract: An elevation regulator of display, comprising a base member 1, and an elevation member 3 moving up and down with respect to the base member 1. The elevation member 3 is provided with a part 6 for fixing a display D. The base member 1 is provided with spiral springs 2, 2 being uncoiled as the elevation member 3 lowers to urge the elevation member 3 upward.Type: GrantFiled: December 13, 2001Date of Patent: April 5, 2005Assignees: Murakami Corporation, Nec-Mitsubishi Electric Visual Systems CorporationInventors: Takashi Ishizaki, Kenichi Hirasawa

Patent number: 6874743Abstract: A direction regulator H of display, comprising a frame M mounting a member 7 capable of elevating/lowering in the height direction X1. A display fixing part 1 is provided to an upper part of the elevating/lowering member 7. The display fixing part 1 comprises a base member 2 having a spherical receiving face 27A. In front of the base member 2, a cap support 3 comprising a spherical cap body 31 having a curvature substantially identical to that of the receiving face 27A is provided to be urged by a spring 9 through the receiving face 27A of the base member 2. A flange 4 is clamped between the base member 2 and the cap support 3. The flange 4 is slidable along the spherical receiving face 27A of the base member 2. The flange 4 is fixed with a display D through an angle regulating member 5.Type: GrantFiled: December 13, 2001Date of Patent: April 5, 2005Assignees: Murakami Corporation, NEC-Mitsubishi Electric Visual Systems CorporationInventors: Atsushi Watanabe, Kenichi Hirasawa
