DETAILED DESCRIPTION OF THE INVENTION
[0025] Referring to the drawings and initially to FIGS. 1-4, a pair
of spectacles in accordance with the preferred embodiment of the
present invention comprise a rim 2 having two ends, two angle
adjusting devices 1 each mounted on a respective one of the two
ends of the rim 2, and two temples 3 each mounted on a respective
one of the two angle adjusting devices 1.
[0026] Each of the two angle adjusting devices 1 includes a
connecting member 11, and a pivot member 12.
[0027] The connecting member 11 of each of the two angle adjusting
devices 1 has a bifurcated first end 110 formed with a
longitudinally extended insertion slot 113 and a transversely
extended circular pivot hole 116 communicating with the insertion
slot 113. The first end of the connecting member 11 has a
semi-circular side. The first end of the connecting member 11 is
formed with a wedge-shaped flexible locking pawl 114 and two
opposite limit plates 115, with the locking pawl 114 being located
between the two opposite limit plates 115. Preferably, the locking
pawl 114 of the connecting member 11 is extended into the insertion
slot 113 and is separated from a peripheral wall of the insertion
slot 113, and the two opposite limit plates 115 of the connecting
member 11 is extended into the insertion slot 113 and is connected
to the peripheral wall of the insertion slot 113.
[0028] The connecting member 11 of each of the two angle adjusting
devices 1 has a second end pivotally mounted on a respective one of
the two ends of the rim 2. Preferably, each of the two ends of the
rim 2 is formed with a forked pivot seat 21, and the second end of
the connecting member 11 is formed with a pivot ear 112 pivotally
mounted on the respective pivot seat 21 of the rim 2 by a screw
member 22.
[0029] The pivot member 12 of each of the two angle adjusting
devices 1 is pivotally mounted in the insertion slot 113 of the
connecting member 11 and has a first end formed with a plurality of
substantially V-shaped locking grooves 122 which are protruded
outward and are arranged in an arc-shaped manner. The locking pawl
114 of the connecting member 11 is detachably locked in either one
of the locking grooves 122 of the pivot member 12.
[0030] The pivot member 12 of each of the two angle adjusting
devices 1 has two sides each formed with a circular pivot axle 123
extended through the insertion slot 113 and pivotally mounted in
the pivot hole 116 of the connecting member 11. The pivot axle 123
of the pivot member 12 has a beveled face 124 to facilitate the
pivot axle 123 of the pivot member 12 entering the pivot hole 116
of the connecting member 11.
[0031] Each of the two temples 3 includes a hollow length adjusting
member 31 mounted on or integrally formed with a second end of the
pivot member 12 of a respective one of the two angle adjusting
devices 1, and a bend 30 having a distal end 300 movably mounted in
the length adjusting member 31. The length adjusting member 31 has
a side wall formed with a corrugated adjusting slot 32, and the
distal end 300 of the bend 30 has a side formed with an adjusting
knob 301 slidably mounted in the adjusting slot 32 of the length
adjusting member 31. The length adjusting member 31 has an end
formed with an arc-shaped recess 34 pivotally mounted on the
semi-circular side of the first end of the connecting member
11.
[0032] In operation, referring to FIGS. 1-5, when the rim 2 is
pressed to move relative to the length adjusting member 31 of the
two temples 3 as shown in FIGS. 5A and 5B, the connecting member 11
is moved with the rim 2 to pivot relative to the pivot member 12,
so that the locking pawl 114 is moved with the connecting member 11
to detach from the respective locking groove 122 of the pivot
member 12 by flexibility of the locking pawl 114. In such a manner,
the connecting member 11 is pivoted relative to the pivot member 12
until the locking pawl 114 is locked in another locking groove 122
of the pivot member 12 as shown in FIGS. 5A and 5B.
[0033] Accordingly, the locking pawl 114 of the connecting member
11 is detachably locked in either one of the locking grooves 122 of
the pivot member 12, so that the angle between the connecting
member 11 and the pivot member 12 is changed arbitrarily so as to
adjust the angle of the rim 2 relative to the temples 3. In
addition, the locking pawl 114 of the connecting member 11 is
closely locked in either one of the locking grooves 122 of the
pivot member 12, so that the connecting member 11 is combined with
the pivot member 12 rigidly and stably. Further, each of the two
opposite limit plates 115 of the connecting member 11 is movable to
abut an edge of the pivot member 12 as shown in FIGS. 5A and 5B,
thereby preventing the locking pawl 114 of the connecting member 11
from releasing from the locking grooves 122 of the pivot member
12.
[0034] Referring to FIGS. 6 and 7, the locking pawl 114 of the
connecting member 11 has a root portion having two sides each
formed with a reinforced rib 1141 to enhance the strength of the
locking pawl 114 of the connecting member 11.
[0035] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
