Description

  The present invention relates to a hinge for glasses, and more particularly to a hinge for glasses that can perform a stable opening and closing operation and can be made compact and lightweight.

  In general, the hinges of the glasses connect the frames respectively provided on the lens holding part and the temple with screws serving as pivot shafts so that the temple can be opened and closed. This hinge can adjust the turning motion of the temple by tightening the screw. When the screw is tightened strongly, the frictional force between the frames increases and the turning of the temple becomes heavy, and when the screw is loosened, the temple turns. The movement becomes lighter.

  However, when the temples are opened and closed, the frames move in pressure contact with each other. Therefore, it is difficult to achieve a smooth opening and closing operation when the temple turns heavy. It becomes easy. As a result, it is difficult to set the temple in a stable state when the temple is opened and attached or when the temple is closed and the glasses are stored. In addition, when the opening and closing operation for rotating the temple is repeated, the frictional resistance against the rotation of the temple gradually decreases, and it is necessary to readjust the tightening degree of the screw.

  For example, in Patent Document 1, an elastic biasing means (spring) is provided in one of the two frame portions, a cam member is provided in the other frame portion, and the rotating member is elastically biased. There is described a pair of glasses that can be set to be pressed against the cam member by means and can be stably set to a predetermined opening / closing position when the one frame portion is opened / closed.

JP 59-188619 A

  In Patent Document 1 described above, since the elastic biasing means (spring) is incorporated in the hinge, the size of the hinge is increased, making it difficult to reduce the weight and size of the spectacle frame. When examining the design of the eyeglass frame, the size of the hinge had to be taken into consideration, and the design freedom was limited.

  Therefore, an object of the present invention is to provide eyeglasses having a hinge that can perform a stable opening and closing operation and can be made compact and lightweight.

  The hinge of the present invention that achieves the above object is a hinge 6 formed by pivotally inserting the temple 3 into the notches 51 and 52 of the armor 5, and has small protrusions 33 and 34 extending in the vertical direction. The frame 3 on the temple 3 side, and the recess 53 or the hole 54 on the side on which the small protrusions 33 and 34 are press-fitted, and the temple 3 is opened and folded. First and second depressions 55 and 57 and first and second ridges 35 that can be engaged with each other at two locations on both the temple 3 side and the armor 5 side so that positioning is performed at two locations. , 36 are provided.

  Preferably, two pieces 31 and 32 on the temple 3 side are provided, and the small protrusions 33 and 34 protrude from the respective pieces.

  Preferably, the first recess is provided on a step portion of the notch of the armor, the second recess is provided on a surface of the protrusion 56 on the notch 51 on the side of the armor 5, and the first ridge is The second bulge is provided on the temple end surface.

  In the above configuration, when the second ridge 36 on the temple 3 side is engaged with the second depression 57 on the armor side, positioning is performed and the temple is fully opened. Positioning is also performed when the first ridge 35 on the temple 3 side engages with the first recess 55 on the armor side, and the temple is completely folded.

  According to the present invention, positioning is correctly performed at two positions, that is, a position where the temple is opened and a position where the temple is folded. Unlike the prior art, a spring or the like is not provided for this purpose, so that the size and weight can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

It is a top view of the spectacles frame which has a hinge based on the Example of this invention. It is an exploded enlarged view of a hinge part. It is the perspective view which looked at the temple terminal junction part from the exterior side. It is the perspective view which looked at the temple terminal junction part from the inner side. (A)-(d) is a cross-sectional view which shows the motion of a hinge.

  As shown in FIGS. 1 to 5, the spectacles 1 of the embodiment of the present invention are entirely made of synthetic resin except for the lens 2. A hinge 6 is provided at a connecting portion between the temple 3 and the armor 5 of the spectacle frame 4. As shown in FIG. 2, the hinge 6 is formed by inserting two pieces 31 and 32 on the temple 3 side into notches 51 and 52 on the armor 5 side so as to be rotatable.

  As shown in FIGS. 2 to 4, the two frames 31 and 32 on the temple 3 side have small protrusions 33 and 34 extending in the vertical direction, respectively. The small projections 33 and 34 are press-fitted into the recess 53 or the hole 54 on the side of the side, whereby the hinge 6 is completed. When press-fitting, the two pieces 31 and 32 are compressed in a direction to approach each other to reduce the distance between them, and then the small projections 33 and 34 are press-fitted using the restoring force. In the completed state, the small protrusions 33 and 34 serve as center pins for rotation.

  In the hinge 6 of the present invention, positioning is performed at two locations, the opened state of the temple 3 and the folded state. Hereinafter, the mechanism for positioning will be described.

  As can be seen from FIG. 2, the notch on the side of the armor 5 has two stages. A wide first stage 51 is located on the open side, and a narrow second stage 52 is located on the lens side. A hemispherical elongated depression 55 (“first depression 55”) is formed on the wall surface forming the second stage 52. Further, a triangular prism-like protrusion 56 lies at the center of the notch 51 on the side of the armor 5, and a hemispherical elongated recess 57 (“second recess 57”) is formed in a portion corresponding to the bottom of the triangular prism. The first and second depressions 55 and 57 both extend in the vertical direction of the glasses.

  Next, as can be seen from FIGS. 3 and 4, a hemispherical elongated ridge 35 (“first ridge 35”) is formed on the outer curved surface of the upper piece 31. A hemispherical elongated ridge 36 (“second ridge 36”) is formed on the temple end surface between the upper and lower frames 31, 32. Both the first and second ridges 35 and 36 extend in the vertical direction of the glasses.

  FIG. 5 shows the relationship between the first and second depressions 55 and 57 and the first and second bumps 35 and 36. FIG. 5A shows a state before joining the alloy 5 and the temple 3. (B) is the position where the temple 3 is opened when the coupling is completed. At this time, the second ridge 36 on the temple 3 side engages with the second recess 57 on the armor side, and positioning is performed. The state where the force is applied and the engagement is released from this state is the folding start state of (c). When the folding is completed, the state (d) is obtained. At this time, the first ridge 35 on the temple 3 side is engaged with the first recess 55 on the armor side, and positioning is performed.

  That is, in the hinge of the present invention, positioning is performed at two locations, the position where the temple 3 is opened and the position where it is folded. Therefore, since it will stay in those positions unless especially force is applied, it can use spectacles in the right position and can be stored in the right position.
