Embodiment 1

[0033] exist Figure 1 ~ Figure 3 Among them, reference numeral 1 is a fixed substrate for holding office equipment such as a liquid crystal display, and reference numeral 2 is a rotating body such as a liquid crystal display. Reference numeral 3 is a hinge mechanism for rotatably mounting the rotating body 2 on the above-mentioned fixed base plate 1 . Reference numeral 4 is a turning portion formed of an arm member, and has a mounting plate 4a, a mounting hole 4b, a rib 4c, a mounting surface 4d, and mounting holes 4e and 4f. The mounting plate 4a is integrally connected with the rotating body 2 through the mounting holes 4b and with screws or the like. Reference numeral 5 is a cylindrical rotating member, which is formed by four stages of cylindrical parts 5a, 5b, 5c, 5d of different diameters and a protrusion 5b1 extending axially on the outer peripheral surface of the cylindrical part 5b. The gasket 6 on the cylindrical portion 5c can be mounted on the mounting surface o...

Embodiment 2

[0041] Figure 4 and Figure 5 Example 2 is shown. The difference between this embodiment and Embodiment 1 is that a torque adjustment member 11 is added. Thus, in Figure 4 and Figure 5 In the embodiment 1, the same reference numerals are attached to the members and parts that are substantially the same as those in the first embodiment, and the description thereof will be omitted.

[0042] like Figure 4 and Figure 5 As shown, in the hinge mechanism of the second embodiment, the torque adjustment member 11 formed to cover the outer peripheral portion of the cylindrical spring member 8 is provided in order to increase the torque. The member 11 has, for example, a hollow cylindrical portion 11a formed of a spring material, an end portion 11d having a hole 11c through which the rotating member 5 passes, and a slit 11b formed in the hollow cylindrical portion 11a along its axial direction. The cylindrical spring member 8 is fitted into the hollow cylindrical portion 11 a...

Embodiment 3

[0053] Figure 11 to Figure 13 Example 3 is shown. Because this embodiment is substantially different from the above-mentioned embodiment only in the structure of the rotating member 5 and the cylindrical spring member 8, so, in Figure 11 to Figure 13 In , members and parts substantially the same as those in the above-mentioned embodiment are denoted by the same reference numerals, and their descriptions are omitted.

[0054] In this example, if Figure 11 and Figure 12 As shown, the rotating member 12 fixed on the rotating part 4 has a flange part 12a, an outer peripheral surface 12b, cutout parts 12b1 and 12b2, and a cylindrical part 12c. The cutouts 12b1 and 12b2 extend axially on the outer peripheral surface to form a concave cross section. Additionally, if Figure 11 and Figure 13 As shown, the cylindrical spring member 13 has a cylindrical portion 13a, a slit 13b, a tongue portion 13a1 and a pair of mounting holes 13c. Tongue portion 13a1 is formed on cylindric...

Abstract

The invention provides an articulating mechanism with simple structure and stable and smooth rotating function. The articulating mechanism comprises a column or cylinder-shaped rotating component (5) having at least one convex strip (5b1) which extends along the axial direction at the outer circumference, and a cylinder-shaped spring component (8), wherein, the cylinder-shaped spring component (8) is rotatablebly assorted on the rotating component (5) and provided with a narrow gap (8c) which is buckled with the convex strip (5b1) and extend axially at the outer circumference; and the rotation of the rotating component (5) and the cylinder-shaped spring component (8) is limited by pressing-sliding the convex strip (5b1) with the inner wall surface of the cylinder-shaped spring component (8) and buckling and separating the convex strip (5b1) with the narrow gap (8c).

Description

technical field [0001] The invention relates to a hinge mechanism applicable to the connection between the base body and the display of a liquid crystal television or a notebook computer, or connecting a cover and a body in other office equipment so that the cover can be maintained at a specified opening angle position. Background technique [0002] The hinge mechanism has been widely used for a long time as one of the mechanism elements of the equipment, and various structures of the hinge mechanism are proposed and sold on the market, but the basic structure of the hinge mechanism is provided with an independent hinge axis. , and a pair of relatively rotating components (base plate and cover plate, etc.) can be rotatably installed on the hinge shaft. In addition, the above-mentioned hinge mechanism has a type in which the pair of rotating members rotate smoothly according to the application, and a type shown in Patent Document 1 below that does not rotate randomly but rota...
