Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hinge that pivotally supports a lid or the like of a housing.
[0002]
[Prior art]
Hinges that support the lid of the housing, etc., feel a slight rotational resistance at the start of rotation when opening and closing the lid, etc. In some cases, a sense of movement is required.
[0003]
Conventionally, in such a case, the cam is fixed to the hinge shaft, the flexible plate is pressed against the cam, and the rotation starts by increasing or decreasing the resistance force that the flexible plate rides on and off the cam. The feeling of rotational resistance increased and decreased at the time and after the start of rotation.
[0004]
[Problems to be solved by the invention]
However, such a conventional hinge has a problem in that it has a large number of parts and cannot be easily assembled.
[0005]
An object of the present invention is to solve such a problem and to provide a hinge with a feeling of movement that has a small number of parts and is easy to assemble.
[0006]
[Means for Solving the Problems]
The present invention includes a spring plate attached to the outer periphery of the shaft in a fixed state and having a concavo-convex surface formed thereon, a protrusion projecting from the convex surface of the concavo-convex surface, and a rotatably fitted to the outer periphery of the shaft. And a plate body having a fitting portion that is pressed against the surface of the spring plate and into which the protruding portion can be fitted, and is fitted with the protruding portion fitted at the start of rotation. Rotational resistance is given by the force of detaching from the portion, and the rotational resistance feeling is reduced by the phenomenon that the protrusion fits into the insertion portion at the end of the rotation.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.
[0008]
FIG. 1 is a perspective view showing an example of an embodiment of the present invention, in which 1 is a stationary member such as a housing, 2 is a rotating member such as a lid, and a cylindrical member is provided at the end of the stationary member 1. A cylindrical portion 3 is formed, and a shaft 4 having a circular cross section is integrally provided on a side surface of the cylindrical portion 3. A fitting hole 6 of a cylindrical portion 5 formed in the rotating member 2 is fitted on the outer periphery of the shaft 4, and the rotating member 2 has the shaft 4 as a center of rotation as indicated by an arrow 7. It is combined so that it can rotate.
[0009]
A ring-shaped spring plate 8 and a ring-shaped plate body 9 are fitted on the outer periphery of the shaft 4 described above, and between the cylindrical portion 3 of the stationary member 1 and the cylindrical portion 5 of the rotating member 2. It is supposed to be sandwiched.
[0010]
The ring-shaped spring plate 8 is bent in the circumferential direction, and the surface thereof is an uneven surface. The outer periphery of the concave portion of the uneven surface has an engaging claw on the back side on the other side of the figure. 10 is protruding, the engaging claw 10 engages with an engaging recess 11 formed in the cylindrical portion 3, and the spring plate 8 is fixed so as not to rotate with respect to the stationary member 1 and the shaft 4. Try to keep on. On the surface which is the convex surface 12 of the concavo-convex surface, two circular protrusions 13 are projected with a phase of 180 degrees.
[0011]
On the outer periphery of the flat ring-shaped plate body 9, an engaging claw 14 protrudes toward the front side of the figure, and this engaging claw 14 engages with an engaging recess 15 formed in the cylindrical portion 5. It is fixed by pair plate body 9 the engaging recess 15. Therefore, when the rotating member 2 rotates about the shaft 4 as indicated by the arrow 7, the plate member 9 also rotates about the shaft 4 together with the cylindrical portion 5.
[0012]
The spring plate 8 and the plate body 9 described above are sandwiched between the tubular portion 3 of the stationary member 1 and the tubular portion 5 of the rotating member 2, and the uneven surface of the spring plate 8. The convex surface 12 of the spring plate 8 is always in pressure contact with the plate body 9 by the elastic force due to the above. The plate body 9 is provided with four insertion portions 16 such as holes or recesses into which the protrusions 13 of the spring plate 8 are fitted with a rotation of 90 degrees.
[0013]
Next, the operation of the apparatus of FIG. 1 will be described.
[0014]
When the rotating member 2 is rotated about the shaft 4 as indicated by an arrow 7, the plate body 9 is also rotated about the shaft 4 along with the cylindrical portion 5 of the rotating member 2. become. On the other hand, since the spring plate 8 is kept in a fixed state, the projection 13 of the spring plate 8 is fitted to the fitting portion 16 of the plate 9 every time the plate 9 is rotated 90 degrees. It comes to escape.
[0015]
When the protrusion 13 fitted in the insertion portion 16 is removed from the insertion portion 16, the protrusion 13 moves on the edge of the insertion portion 16, so that the convex surface 12 of the spring plate 8 is It is necessary to bend so as to be lowered by the height, and the force that pushes down the convex surface 12 of the spring plate 8 gives a rotational resistance feeling to the rotating member 2 at the start of the rotation.
[0016]
At the time when the rotation of the rotating member 2 is finished and the protrusion 13 faces the next insertion portion 16, the protrusion 13 is caused to slide down to the insertion portion 16, so that the rotational resistance of the rotation member 2 is slightly reduced. become.
[0017]
As described above, the protrusion 13 projecting from the convex surface 12 of the spring plate 8 is engaged with or disengaged from the insertion portion 16 of the plate body 9, thereby providing a sense of movement in the rotation of the rotating member 2. Will occur.
[0018]
【The invention's effect】
The present invention can provide a feeling of movement of increase / decrease in rotational resistance during the rotation of the rotation member with a simple configuration, and has an effect of facilitating assembly because the number of parts is small.
