Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a structure for fixing a
side shield for glasses capable of protecting eyes from a foreign
substance, and in particular to a structure for fixing a side
shield for glasses by which it is possible to easily assemble a
side shield by improving a bolt which hinges a glasses leg.
[0003] 2. Description of the Background Art
[0004] When a person wears glasses, since a distance between left
and right glasses legs and a glasses frame, a certain foreign
substance may be inserted into a user's eyes for thereby causing a
viewing problem. In particular, in an industry field, since there
are much foreign substances in the air, a worker may have serious
eye problems.
[0005] Therefore, a side shield is installed in a glasses leg using
screws. In this case, namely, a side shield is fixed to a glasses
leg using screws, an error ratio of product is decreased, and a
workability is decreased.
[0006] Therefore, the applicant of the present invention filed a
Korean utility model No. 2199 in 1999. In the above application, a
fixing pin is used for fixing a side shield to a glasses leg, not
using a screw. The above fixing pin has a body having a certain
size same as a diameter of an installation hole formed in a side
shield. A pin head is expanded in one end of the body. An elastic
piece separated by a cutting portion is formed in another portion
of the body. A curved portion formed in an outer end portion of the
elastic piece together with an engaging shoulder portion is
integrally formed.
[0007] In the above conventional art, when a fixing pin is inserted
into an installation hole formed in a side shield, a side shield is
fixed to a glasses leg by the fixing pin.
[0008] However, in the conventional art, since a certain element
such as a screw or fixing pin is used for fixing a side shield to a
glasses leg, a process for forming a hole in a glasses leg and a
process for forming a hole in a side shield are additionally
performed for thereby increasing the number of work processes.
Therefore, a worker's workability is decreased.
SUMMARY OF THE INVENTION
[0009] Accordingly, it is an object of the present invention to
provide a structure for fixing a side shield for glasses which
overcomes the problems encountered in the conventional art.
[0010] It is another object of the present invention to provided a
structure for fixing a side shield for glasses which is capable of
enhancing a productivity by assembling a side shield by only
installing a glass leg by improving a bolt which hinges a glasses
leg without using an additional element.
[0011] To achieve the above objects, in a side shield for glasses
in which a connection member is installed between a glasses frame
and a glasses lens, and the glasses leg is rotatably installed to
the connection member, so that it is possible to surround a part of
the glasses leg and the connection member and prevent a foreign
substance which is provided through the sides of the glasses, and a
through port is formed in an upper side of the hinge portion
between the glasses leg and the connection member, there is
provided a structure for fixing a shield for glasses in which a
bolt 11 capable of rotatably connecting the connection member 2 and
the glasses leg 3 is installed through a through port 4a of the
side shield 4 in such a manner that a surrounding surface of the
head 11a of the bolt 11 is provided near an inner surrounding
surface of the through port 4a of the side shield 4.
