Foldable spectacle frame
First Claim
1. A foldable spectacle frame comprising a lens frame, an auxiliary temple member having a length corresponding to the vertical width of the lens frame and supported by an outer portion of upper side of the lens frame pivotally movably in a plane substantially orthogonal to the plane of the lens frame, and a main temple member pivoted to the auxiliary temple member rotatably in a plane orthogonal to the plane of pivotal movement of the auxiliary temple member, the spectacle frame being characterized in that the spectable frame comprises:
- a slide member slidable on the auxiliary temple member and having a length permitting a base end thereof to project from the auxiliary temple member,means for moving the slide member in a direction away from the lens frame when the main temple member is folded, andmeans for engaging the slide member with the lens frame by cooperation of the slide member and the lens frame,the slide member being engageable with the lens frame when the main temple member is brought into an unfolded state and disengageable from the lens frame when the main temple member is folded.

Abstract
A foldable spectacle frame having temples which are foldable to a thin form in the same plane as its lens frames without lapping over the lens frames. Each of the temples comprises an auxiliary temple member having a length corresponding to the vertical width of the lens frame and supported by an outer portion of upper side of the lens frame pivotally movably in a plane substantially orthogonal to the plane of the lens frame, and a main temple member pivoted to the auxiliary temple member rotatably in a plane orthogonal to the plane of pivotal movement of the auxiliary temple member. The spectacle frame further comprises a slide member slidably provided on the auxiliary temple member and having a length permitting a base end thereof to project from the auxiliary member, means for moving the slide member away from the lens frame when the main member is folded, and means for engaging the slide member with the lens frame by cooperation of the slide member and the lens frame. The slide member engages with the lens frame when the main member is brought into an unfolded state and disengages from the lens frame when the main member is folded.
