Title: Linking tool for articles and linking structure using said tool
Inventor: WATANABE ISAMU
IPC: F16B7/04
Filed: 2021-01-21
Abstract: A linking tool (4) that can be inserted into a hollow part of a designated article (2) is provided with a plurality of segments (11) including fastening parts (11, 21) constituting a body part (41), sealing parts (12, 22) constituting an insertion part (42), and connecting parts (13, 23) constituting a neck part (43). The fastening parts (11, 21) can be displaced between a basic state in which a gap is opened with respect to an inner surface of the hollow part and an active state of adhering firmly to the inner surface of the hollow part. When the fastening parts (11, 12) are in the basic state, the sealing parts (12, 22) can pass through a through-part (3a) of a counterpart article (3), and when the fastening parts (11, 21) are in the active state, the the sealing parts (12, 22) can undergo integrated displacement with the fastening parts (11, 21) so as to be unable to pass through the through-part (3a). The fastening parts (11, 21) are displaced from the basic state to the active state by the operation of an externally operated member (5), so as to link the articles (2, 3) together.

Title: Rim-lens structure
Inventor: INAMI MASAYUKI
IPC: G02C1/06
Filed: 2021-01-27
Abstract: [Problem] Inserting or changing lenses in rims, as carried out at an optician's store and the like, requires work, time, and cost. However, there is currently no convenient alternative means for this. [Solution] A rim-lens structure that can achieve both a stable hold when lenses are fixed and ease of insertion/removal, and that enables easy lens insertion/removal without the use of tools such as a screwdriver, wherein: rims are designed to be vertically somewhat smaller and horizontally somewhat larger with respect to the lens outline, while the shapes of the rims and lenses are kept substantially the same; the flexibility of the rims is utilized such that the force of the rims trying to return fixes the lenses; when the lenses are fixed, gaps between the rims and each of the lenses are limited to two places horizontally opposite from each other and are as small as possible; and while achieving a stable hold on the lenses by the rims and the lenses restraining each other in a continuous manner along a wide range and in many directions, lens insertion/removal is simplified by a gap-enlarging effect produced by the flexibility of the rims and moving a lens such that the two gaps are merged into one.
