Description

  The present invention connects an open / close member such as a lid, a display, a monitor and the like to an apparatus main body such as a notebook computer or a video camera so as to be openable / closable, and holds the open / close member in an arbitrary open / close state. The present invention relates to a hinge having click stopping means for stably maintaining the closed state of the opening / closing member.

  As a conventional hinge of this type, for example, as shown in Patent Document 1, a plurality of concave portions and convex portions are formed on the same rotation locus of a mounting member and a friction washer that rotate frictionally with each other, and a predetermined rotation is achieved. Some are configured to stop clicking at the corner.

However, in the prior art of Patent Document 1 described above, in order to stop the click only at a predetermined rotation angle (for example, the opening degree 0 ° when the rotating member is closed), a pair of concave and convex portions is formed. Since an unreasonable biased force is exerted on the structure, it is difficult to realize a hinge that is easily deformed and worn, and is stable and durable.
Japanese Patent Laid-Open No. 11-272187

  The problem to be solved by the present invention is to realize a hinge that can solve the problems of the conventional hinge and is stable and durable.

  The present invention connects an open / close member such as a lid, a display, and a monitor to an apparatus body such as a notebook personal computer so that the open / close member can be freely opened and closed, and holds the open / close member in an arbitrary open / close state. A hinge having click stop means for maintaining a closed state; a fixed bracket attached to and fixed to the apparatus main body; a rotary shaft rotatably supported by the fixed bracket and attached to the opening / closing member; A fixed-side control member fixed to the fixed bracket and rotatably inserted in the rotary shaft, and a torque control means with a click function comprising a rotary-side control member that rotates together with the rotary shaft and is movable in the axial direction; Elastic means for urging the rotation-side control member in the direction of the fixed-side control member; and on a specific rotation locus of the fixed-side control member A click concave portion or click convex portion is formed at a fixed position, and a click convex portion or click concave portion that engages with or disengages from the click concave portion or click convex portion is formed at the specific position on the specific rotation locus of the rotation side control member. In addition, a click concave portion or a click convex portion is formed at another position on the other rotation locus of the fixed side control member, and the click is placed at another position on the other rotation locus of the rotation side control member. A click convex portion or click concave portion engaging with or disengaging from the concave portion or click convex portion is formed.

  The hinge of the present invention can realize a stable and durable hinge.

  FIG. 1 is an exploded perspective view of a main part showing an embodiment of the hinge of the present invention. Reference numeral 1 denotes a fixed side bracket, which is attached and fixed to a device main body (not shown). Reference numeral 2 denotes a rotating shaft, which is fixedly attached to an opening / closing member (not shown) of the device. An attachment shaft portion 2a and a flange portion 2b are formed at the end portion of the rotating shaft 2. The attachment shaft portion 2a is inserted into the attachment hole 1a of the fixed bracket 1, and the flange portion 2b is a washer 3. It contacts with the side of fixed side bracket 1 via.

  Reference numeral 4 denotes a torque control means with a click function, which comprises a fixed side control member 4a and a rotation side control member 4b. As is clear from FIGS. 2, 3 and 4, the fixed side control member 4a has a shaft hole 4a-1 and a friction surface 4a-2, and an outer click recess is formed on the outer peripheral side of the friction surface 4a-2. 4a-3 is formed, and an inner click recess 4a-4 is formed on the inner peripheral side. The rotation trajectories of the outer click recess 4a-3 and the inner click recess 4a-4 are different and do not overlap. The mounting shaft portion 2a of the rotating shaft 2 is rotatably inserted into the shaft hole 4a-1. Reference numeral 4a-5 denotes a fixed pin, which is inserted into a pin hole 1b formed in the fixed bracket 1.

  Further, the rotation side control member 4b also has a shaft hole 4b-1 and a surface 4b-2, and an outer click convex portion 4b-3 is formed on the outer peripheral side of the surface 4b-2, and the inner peripheral side. Is formed with an inner click recess 4b-4. The mounting shaft portion 2a of the rotating shaft 2 is inserted into the shaft hole 4b-1 so as to rotate integrally. Since the outer click convex portion 4b-3 is on the same rotation locus as the outer click concave portion 4a-3 of the fixed side control member 4a, they are fitted to each other to exhibit a click stop function. Moreover, since the said inner side click convex part 4b-4 is on the same rotation locus as the inner side click recessed part 4a-4 of the said fixed side control member 4a, it mutually fits. The outer click recess 4a-3 is formed on the rotation side control member 4b, the outer click projection 4b-3 is formed on the fixed side control member 4a, and the inner click recess 4a-4 is formed on the rotation side. The inner click projection 4b-4 may be formed in the control member 4b and the fixed control member 4a.

  In FIG. 1, 5 is a disc spring, which elastically presses the rotation-side control member 4b against the fixed-side control member 4a. Reference numeral 6 denotes a presser washer.

  Since the hinge of the present embodiment is configured as described above, when the open / close member is closed (opening degree 0 °), as shown in FIG. Is fitted into the outer click recess 4a-3 and exhibits a click stop function. Although not visible in FIG. 5A, the inner click convex portion 4b-4 is also fitted into the inner click concave portion 4a-3 at the same time.

  When the opening / closing member is opened and the rotation-side control member 4b is rotated, the outer click projection 4b-3 is disengaged from the outer click recess 4a-3 against the pressing force of the disc spring 5, and at the same time, the inner click The click convex portion 4b-4 is also disengaged from the inner click concave portion 4a-3, and the tip surfaces of the respective click convex portions 4b-3 and 4b-4 are frictionally engaged with the friction surface 4a-2. Is held at an arbitrary angular position.

  As shown in FIG. 5 (B), even if the rotation side control member 4b further rotates and the opening degree reaches 180 °, a recess into which the outer click projection 4b-3 can be fitted is the fixed side control. Since it is not formed on the outer peripheral side of the friction surface 4a-2 of the member 4a (see FIG. 2A), the click stop function does not occur by fitting. In addition, the recessed part which can be fitted also with respect to the said inner side click convex part 4b-4 is not formed in the inner peripheral side of the friction surface 4a-2 of the said fixed side control member 4a. (See Fig. 2 (A))

  The present invention is not limited to the above-described embodiment. In short, a specific rotation position such as a rotation angle of the rotation-side control member 4b with respect to the fixed-side control member 4a being 0 ° (opening / closing member opening 0 °). However, any structure may be used as long as the click stop function works.

It is a disassembled perspective view of the principal part of one Example of the hinge of this invention. It is structure explanatory drawing of the fixed side control member (A) and rotation side control member (B) of FIG. It is the front view (A) of the stationary-side control member of FIG. 1, the side view (B) seen from the arrow view b, and a roll sectional view (C). It is the front view (A) of the rotation side control member of FIG. 1, the ha sectional view (B), and the side view (C) seen from the arrow view E. It is operation | movement explanatory drawing (A) (B) by a fixed side control member and a rotation side control member.
