Abstract
An angle adjustment mechanism for a temple of eyeglasses comprises a square recess at an endpiece of a rim, a hole through the square recess, an abutment member including a square member shaped to conform to the square recess, an annular projection on the square member, a first annular toothed portion spaced from the square member by the annular projection, and a plurality of slits across the first annular toothed portion for providing a flexibility when the first annular toothed portion is compressed, a pivot member pivotably secured to the temple, the pivot member including an annular recess and a second annular toothed portion on the bore of an aperture therethrough, and an engagement member including a plurality of protrusions with latched ends, any two adjacent protrusions being separated by a gap. The protrusions are inserted through the pivot member, the abutment member, the square recess, and the hole for pivotably securing them together wherein the annular recess is engaged with the annular projection and the second annular toothed portion is meshed with the first annular toothed portion.
Description
FIELD OF THE INVENTION
The present invention relates to eyeglasses and more particularly to an angle adjustment mechanism for temple of eyeglasses with improved characteristics.
BACKGROUND OF THE INVENTION
Conventionally, a temple of eyeglasses may be fixed to rim or pivotal about rim. As to the latter, an angle adjustment mechanism is provided at the joint of temple and rim. However, the prior angle adjustment mechanisms have suffered certain deficiencies such as limited flexibility, structural complexity, and inconvenience in use. Thus, it is desirable to provide an improved angle adjustment mechanism for temple of eyeglasses in order to overcome the above drawbacks of prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an angle adjustment mechanism for a temple of eyeglasses comprising a square recess at an endpiece of a rim of the eyeglasses, a hole through the square recess, an abutment member including a square member shaped to conform to the square recess, an annular projection on the square member, a first annular toothed portion spaced from the square member by the annular projection, and a plurality of slits across the first annular toothed portion for providing a flexibility when the first annular toothed portion is compressed, a pivot member pivotably secured to the temple, the pivot member including an annular recessed portion and a second annular toothed portion on the bore of an aperture therethrough, and an engagement member including a plurality of protrusions with latched ends, any two adjacent protrusions being separated by a gap such that the protrusions are capable of inserting through the pivot member, the abutment member, the square recess, and the hole for pivotably securing them together wherein the annular recessed portion is snugly engaged with the annular projection and the second annular toothed portion is meshed with the first annular toothed portion. Thus, it is possible to pivot temple with respect to rim for obtaining an optimized angle therebetween.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1
is an exploded view of an angle adjustment mechanism for temple of eyeglasses according to the invention;
FIG. 2
is a partially assembled view of the
FIG. 1
device;
FIG. 3
is a cross sectional view of the assembled
FIG. 1
device;
FIG. 4
is a perspective view of an eyeglasses incorporating the angle adjustment mechanism according to the invention; and
FIG. 5
is a side view illustrating the angle adjustment operation of the
FIG. 4
temple of eyeglasses.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to
FIGS. 1 through 5
, there is shown a pair of eyeglasses incorporating an angle adjustment mechanism according to the invention. As shown, a square recess
111
is formed at an endpiece
11
of rim
1
. A through hole
112
is formed at the center of square recess
111
. An abutment member
3
is formed and is comprised of a square member
31
shaped to conform to square recess
111
, an annular projection
32
on square member
31
at the external side, a first annular toothed portion
33
spaced from square member
31
by annular projection
32
, and a plurality of (two are shown) slits
331
across first annular toothed portion
33
for providing a flexibility when first annular toothed portion
33
is compressed. A pivot member
4
is pivotably secured to temple
2
by means of a fastener (e.g., screw). Pivot member
4
includes an annular recessed portion
41
and a second annular toothed portion
42
on the bore of a hole therethrough. An engagement member
5
has a plurality of (four are shown) protrusions
51
with latched ends. Each protrusion
51
is separated from an adjacent one by a gap. This is a flexibility design. As such, protrusions
51
of engagement member
5
are capable of inserting through pivot member
4
, abutment member
3
, square recess
111
, and hole
112
for pivotably securing them together wherein annular recessed portion
41
is snugly engaged with annular projection
32
and second annular toothed portion
42
is meshed with first annular toothed portion
33
(see FIGS.
3
and
4
). Referring to
FIG. 5
specifically, user may pivot temple
2
with respect to rim
1
for obtaining an optimized angle therebetween.
While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
Claims
- 1. An angle adjustment mechanism for a temple of eyeglasses comprising:a square recess at an endpiece of a rim of said eyeglasses; a hole through said square recess; an abutment member including a square member shaped to conform to said square recess, an annular projection on said square member, a first annular toothed portion spaced from said square member by said annular projection, and a plurality of slits across said first annular toothed portion; a pivot member pivotably secured to said temple, said pivot member including a second annular toothed portion therethrough and an abutted annular recessed portion; and an engagement member including a plurality of protrusions with latched ends, any two adjacent protrusions being separated by a gap; wherein said protrusions are inserted through said pivot member, said abutment member, said square recess, and said hole for pivotably securing them together with said annular recessed portion being engaged with said annular projection and said second annular toothed portion being meshed with said first annular toothed portion.
