ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a pair of eyeglasses, more particularly to a pair of eyeglasses with coupling members for interconnecting lenses and temples thereof.
2. Description of the Related Art
FIGS. 1 and 2
illustrate a conventional pair of eyeglasses
1
that includes a pair of lenses
11
, a pair of temples
13
, and a pair of coupling members
12
, each of which interconnects a respective lens
11
and a respective temple
13
. Each coupling member
12
has an engaging end
121
that is indented to form a recess
120
which is defined by a recess-defining wall
123
. The recess-defining wall
123
is curved, and has a base
124
and two opposite arms
122
that diverge outwardly from the base
124
. The base
124
of the recess-defining wall
123
is formed with a plurality of alternately disposed first retaining grooves
126
, first retaining tongues
125
, and two opposite first barbs
127
. Each lens
11
has a temple end
111
that is formed with a plurality of second retaining grooves
112
, second retaining tongues
113
, and two opposite second barbs
114
that are formed respectively on two outermost ones of the second retaining tongues
113
and that project in opposite directions away from each other. The retaining tongues
113
are elastic so as to permit engagement between the engaging end
121
of each coupling member
12
and the temple end
111
of the respective lens
11
in such a manner that the first retaining tongues
125
engage respectively the second retaining grooves
112
, that the second retaining tongues
113
engage respectively the first retaining grooves
126
, and that the first barbs
127
engage respectively the second barbs
114
.
The aforesaid conventional eyeglasses
1
is disadvantageous in that since the second barbs
114
project away from each other, a larger recess
120
in the engaging end
121
of each coupling member
12
is required to accommodate the temple end
111
of the respective lens
11
, which results in an increase in the profile of each coupling member
12
.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a pair of eyeglasses that is capable of overcoming the aforementioned drawback of the prior art.
According to the present invention, there is provided a pair of eyeglasses that comprises: a pair of lenses, each of which has a nasal end, a temple end opposite to the nasal end, and opposite first and second faces, the temple end having an end face that extends transversely of the first and second faces to interconnect the first and second faces, and that is indented to form a recess which is defined by a recess-defining wall, the recess-defining wall having two opposite ends that are formed with two opposing barbs which project toward each other, and being formed with a first tongue that is disposed between the opposite ends, that projects into the recess between the barbs, and that cooperates with each of the barbs to define a first gap therebetween; a bridge interconnecting the nasal ends of the lenses; a pair of temples, each of which has a pivot end; and a pair of coupling members, each of which has a pivot end pivoted to the pivot end of a respective one of the temples, a bifurcated end opposite to the pivot end and formed with a pair of parallel arms that project in a first transverse direction relative to the end face of the temple end of a respective one of the lenses, and that define an inner space therebetween, and a pair of opposing second tongues that are disposed within the inner space, that extend in a second transverse direction relative to the first and second faces and the first transverse direction to interconnect the arms, and that define a second gap therebetween. Each of the second tongues has a leading end and an engaging end that is opposite to the leading end and that is distal from the temple end, and extends in the first transverse direction from the engaging end to the leading end. The engaging end has an end face. Each of the second tongues is in snap engagement with a respective one of the barbs in such a manner that the first tongue is snugly fitted into the second gap, that each of the second tongues is fittingly inserted into the first gap between the first tongue and the respective one of the barbs, and that the end face of the engaging end of each of the second tongues abuts against the respective one of the barbs so as to prevent removal of the temples from the lenses.
