Eyeglasses convertible into an eyeglass case

Eyeglasses convertible into an eyeglass case, including a frame, seats, rotary blocks, upper and lower covers, and hinges. The frame has lenses and a larger nose pad at the center. The seats are provided on both ends of the frame and have upper and lower grooves on one side, with a screw hole disposed intermediate of the upper and lower grooves. The rotary blocks have a projection and can turn about an angle of 180 degrees in the seats. The rotary blocks further have a recess on one side with a through hole for receiving a screw rod, whereby the hinge is pivotally secured in the recess. The hinges are provided at front ends of the upper and lower covers that serve as casings of the eyeglass case or earpieces of the eyeglasses.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a structure of eyeglasses, more particularly to a pair of eyeglasses that is convertible into a case for keeping the eyeglasses so as to facilitate carding and prevent possible loss thereof.

(b) Description of the Prior Art

Reference is made toFIG. 1, which shows the prior art. A case1is provided for keeping a conventional pair of eyeglasses12. The case1has a fastening hook11on one side for attaching the case to a pocket or the like. As the eyeglasses12and the case1are two separate articles, the eyeglasses12have to be taken out from the case1for use or put back thereinto for keeping purposes when not in use. Besides, earpieces121of the eyeglasses12have to be extended, or opened so that they can be worn on the user's face. Besides, if the eyeglasses12are lost or broken, the case1may become useless since it may not match other sizes of eyeglasses.

SUMMARY OF THE INVENTION

The present invention relates to a structure of eyeglasses, more particularly to a pair of eyeglasses that is convertible into a case for keeping the eyeglasses so as to facilitate carrying and prevent possible loss thereof.

A primary object of the present invention is to provide a pair of eyeglasses that is convertible into an eyeglass case to facilitate carrying and use.

Accordingly, a preferred embodiment of the present invention includes a frame, seats, rotary blocks, upper and lower covers, and hinges. The frame has lenses and a larger nose pad at the center to prevent slippage. The seats are provided on both ends of the frame and have upper and lower grooves on one side, with a screw hole disposed intermediate of the upper and lower grooves. The rotary blocks have a projection and can turn about an angle of 180 degrees in the seats. The rotary blocks further have a recess on one side with a through hole for receiving a screw rod, whereby the hinge is pivotally secured in the recess. The hinges are provided at front ends of the upper and lower covers that serve as casings of the eyeglass case or earpieces of the eyeglasses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference toFIG. 2, the present invention is shown to comprise a frame2, two seats22, two rotary blocks3, an upper cover202, a lower cover201, and two hinges203. The frame2includes lenses20, left and right portions, and a larger nose pad21at the center between the left and right portions, adapted to provide a stable and elastic support and durability, and to prevent slippage. The seats22are provided at both ends of the frame2, respectively. Each of the seats22includes upper and lower grooves23,24on one side, with a screw hole25at the center. The seats22are provided to allow rotation of the rotary blocks3. Each of the rotary blocks3is provided with a central screw hole32for passage of a screw321. The screw321passes through the central through hole32to be locked in the screw hole25of the seat22. In order that the rotary block can rotate about an angle of 180 degrees, it has a projection33at one corner for matching and engaging the upper or lower groove23,24. When the rotary block3rotates, the projection33can slidably displace from the upper groove23to the lower groove24, or vice versa. Furthermore, in order to cooperate with the path of rotation of the rotary blocks3, the upper and lower grooves23,24of the seats22have openings configured to be curved. Each rotary block3is further provided with a recess34on one side, which has a longitudinally oriented through screwhole31for passage of a screw rod311. The upper and lower covers202,201are adapted to be casings and earpieces of the eyeglasses of the present invention. Insert posts204are provided on inner sides of front ends of the upper and lower covers202,201and are each centrally provided with a through hole205for passage of the screw rod311. The screw rods311secure the insert posts204of the hinges203at the front ends of the upper and lower covers202,201in the recesses34of the rotary blocks3so that the upper and lower covers202,201can rotate about an angle of 90 degrees with respect to the rotary blocks3. Furthermore, the upper cover202is provided with a fastening hook206on an outer side thereof for attaching the eyeglasses to a pocket or the like.

FIG. 3shows the eyeglasses of the present invention in an opened state of use andFIG. 3Ais a schematic view illustrating displacement of a projection with respect to upper and lower grooves of a seat of the present invention. Referring toFIGS. 4 and 5, when it is desired to convert the eyeglasses of the present invention into a case, it is only necessary to turn the upper cover202along with the hinge203and the rotary block3connected thereto about an angle of 180 degrees, using the screw rod321as an axis. At this point, the projection33on the rotary block3will displace from the upper groove23to the lower groove24of the seat22and be positioned (see FIG.4A), so that the shape of the frame2, the upper cover202with the fastening hook26, and the lower cover201resembles the letter “N”. Then, the upper and lower covers202,201turn about an angle of 90 degrees by means of the insert posts204of the hinges203that pivotally tun within the recesses34on one side of the rotary blocks3using the screw rods311as an axis. At this time, the upper and lower covers202,201are brought to rest against front and rear sides of the frame2, respectively, to envelop the same, as shown in FIG.5. It can therefore be seen that the eyeglasses of the present invention are convenient to carry. If it is desired to resume the original shape of the eyeglasses, it is only necessary to turn the upper and lower covers in the opposite directions. Certainly, it should be understood that the upper and lower covers202,201can be pivotally connected to the frame2to allow turning thereof by other means as that exemplified above.
