The rim 13 attached to the movable frame 9 is flipped up by obtaining a boosting effect by obtaining a boosting action and exceeding the limit of the conventional miniaturization of elastic force generation. The rim 13 can rotate around the shaft 1 and the flip-up shaft 8, and the rim 13 can go out from the spectacle main frame 10 to the front. Further, the spring A 3 and the spring B 6, which are one form of the embodiment of the elastic body, can be used. Due to the action, a thickening action is generated at the meshing part, and it can be fixed at any angle at any time.

Description

  The present invention relates to a flip-up spectacle frame.

Conventionally, various kinds of flip-up glasses have been proposed, but in a rotatable structure, the angle maintenance at a desired angle, rotation stability, and durability are insufficient in practical use.
Also, the complexity of the rotating mechanism has been a problem.

  In addition, since the movable frame has a structure configured on the front surface of the spectacle main body, there is a drawback in that the design tends to be complicated and complicated.

  Conventionally, when an elastic force is applied to the side surface to make the angle maintenance function, a minimum required size for obtaining a necessary frictional force is required to be large, which prevents a reduction in the size of the mechanism.

  The problem to be solved is that the mechanism part for the movable frame part to jump up to the front is set at a position where it was not possible to take in the past, especially by installing it coaxially with the main body part or on the back side. It is a point to incorporate so as not to damage.

  In addition, a plurality of elastic force generating portions are dispersed in both the spectacle main frame and the movable frame portion to obtain a boosting action, and the size can be reduced beyond the limit of downsizing of the conventional elastic force generation. .

  Claim 1 of the present invention assumes that any position can be set without defining the relative positional relationship between the movable frame portion and the main frame. Claim 2 of the present invention particularly relates to the movable frame portion as the main frame. The main feature is that it is located on the back of the.

  A third aspect of the present invention is characterized in that the main axis is a structure in which the rotational axis of the flip-up is positioned on the back surface of the spectacle main body, and a mechanism for adjusting the pressure is provided.

  The main feature of claim 4 of the present invention is that the rotational axis of the flip-up is formed in a part of the spectacle main body part and integrated with the mounting shaft, and the rotational axis is coaxial with the spectacle main body part.

  In addition, it is natural means to incorporate the elastic force as a single unit, but it has a means to obtain a boosting action using a plurality of elastic forces, and it is possible to obtain a maintenance force for a large jumping position, Further, it has means for causing the elastic body to act in the rotational direction, obtaining a rotational force, and performing a flip-up operation.

  The flip-up glasses according to claims 1 and 2 of the present invention are improved in design because the movable frame portion and the flip-up mechanism portion are hidden behind the spectacle main body portion in that the movable frame portion jumps to the front surface while the movable frame portion is present on the back surface. In addition, since a boosting action can be obtained by incorporating and dispersing a plurality of elastic forces, the flip-up mechanism can be made smaller than before.

  Claim 3 of the present invention is configured such that the rotation axis is located on the back surface of the spectacle main body, so that the center of the rotation axis is located between the spectacle main body and the movable frame, which is a conventional method. Compared to the above, there is an effect that it is possible to take a structure in which the thickness of the flip-up mechanism can be reduced.

  The invention according to claim 4 of the present invention has a structure in which a sliding rotation shaft portion is provided on the spectacle body itself and this is used as a rotation shaft, and the flip-up mechanism portion is a sliding rotation shaft portion, which could not be achieved conventionally. Therefore, it has the effect of being able to escape from the conventional structural design in which the flip-up mechanism part protrudes from the spectacle body.

  The purpose of jumping to the front while positioning the flip-up mechanism and movable frame on the back of the spectacle body was achieved while pursuing design while obtaining stable operation with the smallest part shape.

  Washers A and B are combined to avoid friction between springs A and B and the flip-up shaft.

  Since it is configured in this way, the rim 13 attached to the movable frame 9 can be rotated around the rotation axis and the flip-up axis, and the rim 13 can go out from the spectacle body 10 to the front surface. A thick contact action is generated in the meshing portion by the action of the springs A and B which are one form of the embodiment of the elastic body, and an effect that can be fixed at any angle is obtained.
