Each of the side portions 112 has a pivot block 113 formed on a distal. rear end thereof. Each of the pivot blocks 113 has a pivot, hole 114 extending vertically therethrough. Each of the bows 12 has a rear ear support end 121 for hanging on one of the ears of the wearer, and a front, pivot end 122 formed with upper and lower pivot lugs 13 that extend forwardly. The pivot block 113 of each' of the bow engaging portions 112 extends between the upper and lower pivot lugs 123 of a respective one of the bows 12. Each of the upper and lower pivot lugs 123 is formed with a threaded hole 125 aligned with the pivot hole 114 in the respective pivot block 113. Each of the bows 12 is connected threadedly to a respective one of the lateral portions 112 by means of a screw 13 that extends through the holes 125 in the bow 12 and the pivot hole 114 in the respective pivot block 113.

The following are some of the drawbacks of the 2 conventional eyeglasses:

1. The aforesaid eyeglasses employs screws 13 for connecting threadedly the bows 12 and the lens piece 11, thereby requiring the use of a tool that leads to inconvenience during assembly.

2. After being in use for a period of time, wearing of the screw threads on the screws 13 can easily occur and can lead to loosening of the screws 13.

3. Since the pivot blocks 113 are visible from the lateral sides of the eyeglasses, the aforesaid eyeglasses has an unattractive appearance.

Therefore, the object of the present invention is to provide a pair of eyeglasses that can be easily assembled without the need for using a tool.

According to one aspect of the present invention, a pair of eyeglasses includes a lens unit, an elongated frame unit and a pair of elongated bows.

The lens unit is a unitary lens piece having left and right lens portions. Each of the left and right lens portions has a top edge, front and rear sides, an engaging hole that extends through the front and rear sides and that is disposed adjacent to the top edge, and an entrance groove that extends vertically from the top edge to the engaging hole and that forms a restricted access to the engaging hole.

The elongated frame unit includes left and right frame members, each having a lens engaging portion with 3 a top wall and front and rear walls that depend downwardly and respectively from front and rear edges of the top wall and that cooperate with the top wall to confine a receiving groove. Each of the left and right lens portions extends into the receiving groove in the lens engagiag portion of a respective one of the left and right frame members with the top edge being confronted by the to,p wall, and the front and rear sides thereof being confronted by the front and rear walls of the respective one of the lef t and right f rame members. The lens engaging portion of each of the left and right frame members further has an engaging post that extends across the front and rear walls and that engages the engaging hole in the respective one of the left and right lens portions. Th' engaging post is slightly smaller than the engaging hole but is slightly larger than the entrance groove to permit retention of the left and right frame members on the left and right lens portions.

Each of the left and right frame members further has a bow engaging portlion that extends rearwardly from one end of the lens engaging portion and that has a respective one of the elongated bows connected pivotally thereto.

According to another aspect of the present invention, a pair of eyeglasses includes a lens unit, an elongated frame unit and a pair of elongated bows.

The lens unit has a top edge and left and right ends.

4 The elongated frame unit has a lens engaging portion mounted on the top edge of the lens unit, and left and right bow engaging portions that extend rearwardly from the lens engaging portion at the left and right ends of the lens unit. Each of the bow engaging portions has a distal connecting end formed with a pivot block. The pivot block has top and bottom sides, a pin hole that extends through the top and bottom sides, and an entrance slit that extends radially from the pin hole and that forms a restricted entrance to the pin hole.

Each of the elongated bows has a rear ear support end adapted for hanging on one of the ears of the wearer, and a front pivot end formed with upper and lower pivot lugs on an inner wall surface thereof. The pivot block of each of the bow engaging portions extends between the upper and lower pivot lugs of a respective one of the elongated bows. The pivot end of each of the elongated bows further has a pivot pin that extends uprightly across and that interconnects the upper and lower pivot lugs, and that engages the pin hole in the respective one of the bow engaging positions. The pivot pin is slightly smaller than the pin hole but is slightly larger than the entrance slit to permit pivotal retention of the elongated bows on the left and right bow engaging portions.

Other features and advantages of the present invention will become apparent in the following 4 5 detailed description of the preferred embodiment with reference to the accompanying drawings, of which:

Figure 1 is a partly exploded perspective view of pair of conventional eyeglasses; Figure 2 is a partly exploded perspective view of preferred embodiment of a pair of eyeglasses according to the present invention; Figure 3 is a fragmentary sectional view illustrating how a frame member is connected to a lens unit according to the present invention; and Figure 4 is a fragmentary sectional view illustrating how albow is connected to the frame member according to the present invention.

Referring to Figures 2 to 4, according to the preferred embodiment of the present invention, a pair of eyeglasses is shown to include a lens unit 2, a pair of frame members and a pair of elongated bows 4.

The lens unit 2 is formed as a unitary lens piece, has left and right lens portions 21, and a nose bridge portion 2 2 adapted,f or hanging on the nose of the wearer.

Each of the left and right lens portions 21 has a top edge 211, front and rear sides 212, 213, two engaging holes 23 that extend through the front and rear sides 212, 213 and that are disposed adjacent to the top edge 211, and two entrance grooves 24 that extend vertically from the top edge 211 to the engaging holes 23, respectively. Each of the entrance grooves 24 forms 6 a restricted access to a respective one of the engaging holes 23.

Each of the frame members 3 has a lens engaging portion, and a bow engaging portion extending rearwardly from the lens engaging portion. Each of the lens engaging portions has a top wall 31 and front and rear walls 32 that depend downwardly and respectively from front and rear edges of the top wall 31 and that cooperate with the top wall 31 to confine a receiving groove 33. Each of the left and right lens portions 21 extends into the receiving groove 33 in the lens engaging portion of a respective one of the frame members 3 with the top edge 211 being confronted by the top wall 31, and the front and rear sides 212, 213 thereof being confronted by the front and rear walls 32 of the respective one of the frame members 3, as shown in Figure 3. The lens engaging portion of each of the frame members 3 further has two engaging posts 34 that extend parallelly across the front and rear walls 32 and that engage the engaging holes 23, respectively, in the respective one of the left and right lens portions 21. The engaging posts 34 are slightly smaller that the engaging holes 23 but are slightly larger than the entrance grooves 24 to permit retention of the frame members 3 on the left and right lens portions 21. Each bow engaging portions has a distal connecting end formed with a pivot block 35. Each pivot block 35 has 7 top and bottom sides 351, 352, a pin hole 36 that extends through the top and bottom sides 351, 352, and an entrance slit 37 that extends radially from the pin hole 37 and that forms a restricted entrance to the pin hole 37.

Each of the elongated bows 4 has a rear ear support end 41 adapted for hanging on one of the ears of the wearer, and a front pivot end 45 formed with upper and lower pivot lugs 42 on an inner wall surface 45 thereof.

The pivot block 35 Of each of the bow engaging portions extends between the upper and lower pivot lugs 42 of a respective one of the elongated bows 4. The front pivot end 45 of each of the elongated bows 4 further has a pivot pin 43 that extends uprightly across and that interconnects the upper and lower pivot lugs 42, and that engages t le pin hole 36 in the respective one of the bow engaging portions, as shown in Figure 4.
