| 136 | Apparatus with torsionally stressed conductors routed through a hollow articulated hinge | US868401 | 1986-05-29 | US4825395A | 1989-04-25 | Ralph W. Kinser, Jr.; David L. Shriver; Judith A. Layman |
| Conductors of a flexible printed circuit routed through a hollow two axis articulated hinge allow a calculator with rotating case halves to possess a keyboard portion in each half of the case. The conductors routed through the hollow articulated hinge are generally centered about one axis of hinge rotation for approximately half the length of the axis, whereupon they transition by either a U-turn or a jog to continue as centered about the other axis of hinge rotation. The conductors may be an integral part of a flexible membrane keyboard assembly having portions located in both halves of the calculator's case. Strain reliefs at the locations where the conductors traverse the case halves, and two in the hinge, at about the center thereof, limit and apportion the torsional flexing experienced by the conductors. The torsional flexing experienced by the flexible conductors increases the number of cycles of rotation they can undergo without breaking, as compared to conventional bending. The hollow articulated hinge allows one case half to rotate one full revoltuion about the other, so that the calculator can be opened and held in one hand. By being within the hollow hinge the conductors are protectd from injury. | ||||||

| The invention is directed to a membrane switch comprising a first layer 30 of flexible insulating material and a second layer 50 having relatively inflexible characteristics, each layer 30, 50 having an array of conductors 40, 54 disposed thereon and defining a plurality of switch point areas over a substantial portion of the respective layers. The first sheet is transparent and carries visible symbols on the inner surface thereof formed by a first layer 36 of inks printed thereon and further includes a barrier coating over such symbols to provide contrast therefore. The first array 40 of conductors is printed on the barrier coating. The second array 54 of conductors is printed on the inflexible layer. The first and second arrays 40, 54 of conductors are connected to respective voltage sources, preferably by further arrays of conductors 42, 56 disposed over at least portions of the first and second arrays, 40, 54 the further arrays 42, 56 being of a material having a higher conductivity than the material used for the first and second arrays 40, 54. Spacer means 58 for the switch is formed by printing an array of spaced apart dots of a dielectric and insulating coating on top of at least one of the arrays of conductors in the defined switch point areas to hold the switch point areas normally apart until pressure is placed thereupon to deform the first sheet 30 and effect a switch closure between corresponding switch point areas of the arrays 40, 54. A method for making the switch is also disclosed. | ||||||

| A key switch adapted to raise or lower a key top according to need is disclosed. The key switch includes a key top, a link assembly comprised of two link members and operatively connected to the key top, which is retracted by a pressure on the key top and extended by release of the pressure and which has an elastic member at its lower end, an FPC placed on a frame of a keyboard to recognize pressing of the key top, and a plate movably placed on the FPC, to which a lower end of one of the link members is connected, and which has an elastic supporting member being in contact with the elastic member of the link assembly. When the key top is pressed down, the link assembly is retracted while compressing the elastic member of the link assembly and the elastic supporting member of the plate. When the link assembly is further lowered, an elastic resistance of the elastic supporting member is suddenly increased, and thus the elastic member of the first link member is suddenly bent and quickly lowered, thereby affording a click sense to a user and enabling the bent portion of the elastic member to press the FPC. | ||||||

| PURPOSE: A keyboard capable of draining water and a notebook computer having the same are provided to prevent elements mounted on a motherboard from being damaged by discharging a water dropped on the keyboard to an exterior. CONSTITUTION: A draining hole(44) is formed at a predetermined portion of the keyboard(40) comprising a plurality of buttons mounted on the upper surface of a base plate. A guidance groove(14), located at the lower portion of the draining hole(44), guides the liquid or dirt to be discharged. A discharging hole(15) is formed at the other side of the guidance groove(14) and discharges a liquid or a dirt toward an exterior of the main body(10). A guidance unit(13) includes the draining hole(44), the guidance groove(14), and the discharging hole(15). The guidance unit(13) is formed at the upper cover(11) of the main body(10). A bending unit, which is bent upwardly, is formed at one end of the base plate. The liquid or dirt is discharged toward an exterior through a battery button combining site located at the lower portion of the main body(10) or the guidance groove(14). | ||||||
