Abstract: A linkage structure for rim and spectacle lenses and spectacles, comprising a rim and two spectacle lenses. The rim comprises left and right half rims. Characteristics: there is a holding groove inside the outer ends of two half rims respectively, connected to a turning block rotatablely. There is a bulge on the outer ends of two spectacle lenses respectively. The bulge is held in the holding groove of half rim. The turning block is turned, one end supports the bulge of spectacle lens, the bulge of spectacle lens is confined in the holding groove of half rim, and it is turned reversely to release one end from the spectacle lens. There is an elastic piece between the turning block and outer end of half rim. The elastic piece applies elastic pretightening force to limit the contrarotation of turning block.

Abstract: A new type of rim and spectacle frame and spectacles. The rim comprises left and right parts, each part has an upper support arm and a lower support arm for gripping the spectacle lens. The inner end of upper support arm is connected to the inner end of lower support arm. Characteristics: the outer end of upper support arm is connected to a turning block rotatably. There is an extension part on the outer end of lower support arm. The turning block rotates to fix one end to the extension part of lower support arm, and it rotates reversely to separate one end from the extension part of lower support arm. There is an elastic piece between the turning block and the outer end of upper support arm, the elastic piece applies elastic pretightening force to limit the contrarotation of turning block.

Abstract: An adjustable rimless glasses for easy removal, comprising rimless lens, temples and nose pads, said rimless lens has outwardly extending protruding portions on both sides; in the front ends of two temples, there are insert holes, rimless lens protruding portions are embedded in the insert hole; in the front ends of two temples are pivoted in the rotator. The rotators can connect with or separate from the exposed part of the rimless lens protruding portions by rotation, so that the rimless lens protruding portions can be located or pulled out of the insert holes. Said nose pads comprise pad, pad arms, fixed axle and base. By the operation of the rotator, temples and rimless lens can be fixed or separated to complete the fast disassembly process of the temples. During the temple assembly process, it does not need the help of screwdriver.

Abstract: A method of forming a polarized optical lens including an optical lens of certain curvature and a polarized piece, wherein the polarized piece is made up of cellulose protective film, adhesive and polarized thin film, and is pressed to matched curvature as injected and plasticized optical lens. The cellulose protective film of the polarized piece is then peeled off, and through the use of injection and plasticization principle, polarized thin film is combined and pasted to the inner surface or outer surface of the optical lens. This synthesized lens is then placed in the ring of an optical mold. Light adjustment and color change liquid colophony is then injected through a through-hole in the ring, and through the clamping of synthesized lens and light adjustment and color change liquid colophony, the whole set then solidifies and forms a shape.

Abstract: The present invention provides a polarizing glass consisted of a polarizing film and an optical substrate, wherein said polarizing film is laid on the external of internal surface of the optical substrate. Said polarizing film is coated with glue on the surface contacting with said optical substrate, and by pressing them together to form an integrated piece. Said optical substrate may be made of PA, AC, OPET or other optical material. Because the thickness of the glass can be decreased greatly to only one piece, so that the material may be saved, and the weight is reduced, simultaneously due to laying the polarizing film in front of said optical substrate, the eye sight is became more clearly and smoothly.

Abstract: A precast concrete pile is provided which has spaced apart concavities disposed in its inner or outer peripheral wall surface. The spaced apart concavities partially extend into the wall surface and terminate with frangible end portions. These end portions break under pressure of mortar pumped into the pile body, thereby forming apertures through which the mortar flows from the pile into the ground adjacent the pile. The precast concrete pile, after being driven into the ground, has a hydraulic sealing apparatus suspended at a desired level within the pile. The hydraulic sealing apparatus is filled with oil to cause radial swelling of the rubber packing to seal off a hollow space within the pile under the packing, and mortar is pumped under pressure into the sealed space until the concavities burst open to enable internal mortar to penetrate the ground surrounding the pile.
