Spacer device for spectacles frames to maintain arms spaced apart
A recently granted patent (Publication Number: US11726352B2) describes a spacer device for frames of spectacles that helps maintain the arms of the frame spaced apart from each other and from the front mount when the arms are folded onto the mount. The device includes a spacer member with a defined thickness and opposing surfaces. The member extends in a main direction and has opposing faces for contact with the front mount and the folded arm. The spacer member also features a channel that extends transversely through the thickness and is positioned between the faces. The channel is delimited by walls that face each other and are connected to a base surface. The channel is designed to be engaged by the first folded arm, keeping it spaced apart from the mount and the adjacent arm. Importantly, the face of the spacer member intended for contact with the front of the frame has a concave surface profile.
The patent also includes several additional claims. The walls of the channel are described as extending parallel to each other, and they are connected to the base surface with a curved surface profile. The channel itself extends perpendicularly to the main direction of the spacer member. The distance between the walls of the channel is specified to have a value between 2 mm and 7 mm. The thickness of the spacer member is stated to be between 5 mm and 12 mm. The channel is positioned in the member at a distance from the face intended for contact with the front mount, which is greater than the distance between the channel and the opposing face. Finally, the spacer member can be constructed from various materials, including expanded polymer materials, micro-cellular expanded materials or micro-cellular foams, and expanded elastomer materials.
This patent introduces a spacer device that addresses the issue of maintaining the proper spacing between the arms of spectacles when folded onto the front mount. By utilizing a spacer member with a concave surface profile and a channel for engagement with the first folded arm, the device ensures that the arms remain spaced apart from each other and the mount. The specific dimensions and materials mentioned in the patent provide further details on the design and construction of the spacer device. This innovation could potentially improve the functionality and durability of spectacles, enhancing the user experience.
