ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
In general, the present invention relates to an eyeglasses lens-installing apparatus. More particularly, the present invention relates to an improved eyeglasses lens-installing apparatus for installing a lens on connecting members of a temple and a bridge of eyeglasses. For example, the present invention relates to an eyeglasses lens-installing apparatus which is applied to rimless eyeglasses.
2. Description of the Prior Art
FIG. 51
is a perspective view showing an example of a conventional eyeglasses lens-installing apparatus which constitutes the background of the present invention. An eyeglasses lens-installing apparatus
1
includes a lens
2
having a circular through-hole
2
a
formed therein. A male screw member
4
fixed to one end of a bridge
3
is inserted in a direction toward rear through the lens
2
from the front side thereof. At the rear side of the lens
2
, a male screw portion
4
a
of the male screw member
4
, is screwed into a nut member
5
. One end of a pad arm
7
supporting a pad
6
is fitted into a cut-out portion
8
formed at a portion of the peripheral surface of the lens
2
and locked thereto. Although not shown in
FIG. 51
, the other lens is installed at the other end of the bridge
3
by using an eyeglasses lens-installing apparatus similar to that described above. Although not shown in
FIG. 51
, the lens is installed on the lug (a front part of the frame connected with the temple and the lens) of the frame by an eyeglasses lens-installing apparatus similar to the above-described apparatus.
However, in the conventional eyeglasses lens-installing apparatus
1
, the male screw member
4
is inserted through the lens
2
from the front side toward the rear side, and the male screw member
4
is screwed into the nut member
5
at the rear side of the lens
2
. Thus, the male screw member
4
and the nut member
5
having angled portions are constructed to project from the rear surface of the lens
2
. Thus, when the lens
2
is wiped with a cleaning cloth or the like, the cloth is likely to be caught by the projected parts and may be torn. That is, the projected parts inconvenience a user during polishing of the lens
2
installed on the eyeglasses lens-installing apparatus
1
. Further, when the user collides with an object and a shock is applied to the eyeglasses, the wearer's face may be injured by the projected parts.
In addition, when the eyeglasses lens-installing apparatus
1
is used to install the lens
2
on the lug, the circular through-hole
2
a
may cause the neck portion of the male screw member
4
to rotate together with the nut member
5
in the through-hole
2
a
of the lens
2
relative to the surface of the lens
2
. That is, the lens
2
may be loosened at the portion at which the lens
2
and the bridge
3
are connected with each other and the portion at which the lens
2
and the lug (not shown in
FIG. 51
) are connected with each other. Thus, the conventional eyeglasses lens-installing apparatus
1
is incapable of holding the lens
2
firmly thereon.
SUMMARY OF THE INVENTION
To overcome the problems described above, preferred embodiments of the present invention provide an eyeglasses lens-installing apparatus which is capable of holding a lens thereon without loosening the lens, allowing a user to polish the surface of the lens easily, and allowing a user to safely wear eyeglasses.
According to one preferred embodiment of the present invention, an eyeglasses lens-installing apparatus includes a connection member having a columnar member adapted to be inserted into a through-hole formed in the lens at a position in the vicinity of an edge of the lens and a fastener having a fixing part to be fixed to the columnar member. The connection member and the fastener are constructed so that when the fixing part of the fastener is fixed to the columnar member, the lens is sandwiched between a part of the connection member positioned at a lens surface side thereof and a part of the fastener positioned at a lens surface side thereof, with the connection member and the fastener being in close contact with the lens.
In another preferred embodiment, an eyeglasses lens-installing apparatus includes a connection member having a columnar member adapted to be inserted into a through-hole formed in the lens at a position in the vicinity of an edge of the lens and a fastener which has a fixing part having a convex portion or a concave portion disposed thereon and which is fitted into the columnar member. The connection member and the fastener are constructed so that when the fixing part of the fastener is fitted into the columnar member, the lens is sandwiched between a part of the connection member positioned at a lens surface side thereof and a part of the fastener positioned at a lens surface side thereof, with the connection member and the fastener being in close contact with the lens.
The columnar member of the connection member preferably has a substantially elliptical shape in cross section so that the columnar member is fitted into a substantially elliptical through-hole formed in the lens. The connection member also preferably has a lens-sandwiching part integral with the columnar member and closely contacting a part of a surface of the lens.
The fastener preferably includes a fastening portion confronting the lens-sandwiching part of the connection member so that the lens is sandwiched between the fastening portion and the connection member.
The fastener may also include a fixing member including a head part and a fixing part including a convex portion or a concave portion which is fixed to the columnar member and integral with the head part and a close-contact member interposed between the head part of the fixing member and the surface of the lens, with the close-contact member positioned on the periphery of the convex portion or the concave portion of the fixing member so as to contact the fixing member and at least one part of the lens closely with each other.
A screw portion provided on the fixing part of the fastener is preferably screwed on a screw portion located on a fixing part of the columnar member to fix the fastener to the connection member.
A male screw portion is preferably disposed on the periphery of the convex portion of the fixing part of the fastener and a female screw portion is preferably disposed on a portion of the columnar member of the connection member such that the portion is positioned in the vicinity of a front end of the columnar member to fix the fixing part of the fastener to the columnar member.
A female screw portion is preferably disposed on an inner part of the concave portion of the fixing part of the fastener and a male screw portion is preferably located on a portion of the columnar member of the connection member such that the portion is positioned in the vicinity of a front end of the columnar member to fix the fixing part of the fastener to the columnar member.
The close-contact member is preferably installed on the periphery of the fixing part of the fastener.
The close-contact member may also be installed on the periphery of the convex portion of the fixing part of the fastener.
The close-contact member is preferably made of a relatively soft material.
The columnar member of the connection member preferably has a hole to which the fixing part of the fastener is fixed.
A convex portion to be fitted into a hole and/or a stepped portion provided on the lens is preferably located on the lens sandwiching part of the connection member.
The connection member preferably has an outer shape which corresponds to the shape of the stepped portion located on the lens so that when the connection member is fixed to the lens, the stepped portion allows the connection member to be fixed to the lens closely.
A convex portion includes a pin positioned in the vicinity of the fixing part of the fastener and projecting from the lens sandwiching part of the connection member toward the lens to fix the lens to the lens sandwiching part by inserting
