(10) FIG. 4 is a view illustrating a state of using a pin-detachment guide member according to an embodiment of the present invention. FIG. 5 is an exploded perspective view of a core portion of FIG. 4.

(11) The present invention relates to a side shield B applicable to industrial glasses.

(12) Specifically, it should be understood that the present invention relates to a pin-detachment guide member 300 capable of fixing and detaching more easily and conveniently the side shield B to and from glasses.

(13) As shown in FIGS. 4 and 5, the pin-detachment guide member 300 may be widely applied to industrial glasses as well as conventional glasses. For example, when the pin-detachment guide member 300 is applied to glasses as shown in FIG. 4, the side shield B is installed to the temple of glasses for the purpose of protecting the eyes and face of a wearer, so that the intended goal may be achieved.

(14) That is, the pin-detachment guide member 300 is provided to solve the problems that an error rate is high and workability is degraded since the side shield is fixed through a screw coupling scheme, glasses may be damaged because the hole is directly formed in the temple of glasses, it is very inconvenient to disassemble the side shield if once the side shield is assembled because the convenience in use is not at all considered, the use of the side shield is very complicated, and the side shield may be damaged upon dissembling the side shield so that the extra cost for repurchasing the side shield may be required.

(15) First, in the pin-detachment guide member 300 of the present invention, the side shield B includes an inserting member C having upper and lower wings D and E and formed on an inside surface thereof. The side shield B is fixed to the temple of glasses by allowing the pin-detachment guide member 300 to perforate into the inserting member C in up and down directions. In this case, an inserting protrusion 400 is further provided to the temple A to induce the side shield B to be intimately coupled to the temple A and it will be described below.

(16) The inserting member C, into which the temple is inserted and fixed, is a conventional inserting member. In addition, the inserting member C may be divided into upper and lower wings D and E for the purpose of convenience of the description. An upper inserting part 322 of the pin-detachment guide member 300 is disposed in the upper wing D and a lower inserting part 321 of the pin-detachment guide member 300 is disposed in the lower wing E. To this end, it is preferable that the lower wing and the lower inserting part have coupling holes (to which any reference numerals are not assigned), of which diameters are narrower than those of coupling holes of the upper wing and the upper inserting part.

(17) FIG. 3 is a perspective view showing the pin-detachment guide member for fixing a side shield according to an embodiment of the present invention.

(18) As shown in FIG. 3, the pin-detachment guide member 300 includes a knob 310 held by a hand of a user, a detachable member 320 restricted in inner spaces of the upper and lower wings D and E of the inserting member C and the inserting protrusion 400 when the detachable member 320 is separated by a rotation of the knob 310, and a separation part 330 interposed between the knob and the detachable member to be separated by torsion of left and right rotations.

(19) As describe above, the knob 310 is an element directly held and rotated by a user and may have a specific shape which allows a user to easily grip the knob 310 for convenience in use.

(20) The detachable member 320, which is a core element of the present invention which allows the side shield B to be coupled to the temple A of glasses, is separated from the knob 310 by the movement of the knob 310 so that the detachable member 320 is placed in the upper and lower wings D and E of the inserting member C and the inserting protrusion 400. In more detail, the detachable member 320 includes a lower inserting part 321 introduced into and restricted in the lower wing E of the inserting member C, an upper inserting part 322 introduced into and restricted in the upper wing D of the inserting member, and a screw part 323 disposed between the upper and lower inserting parts and engaged with the screw thread in the inserting protrusion 400.

(21) In addition, the separation part 330, which is an element of the present invention which is separated by torsion by the rotation thereof, preferably has a thickness less than those of any other portions so that the detachable member 320 is easily separated from the knob 310.

(22) That is, since a main point of the present invention is to remove an object, which allows the side shield to be conveniently fixed and installed to the glasses and is employed in a pin type in order to fix the side shield, in more easy and convenient scheme, to this end, the inserting protrusion 400, which has a screw thread formed on one surface of the temple A, is integrally formed on the temple A, the pin-detachment guide member 300 is introduced into an inner space of the upper and lower wings D and E which are disposed to overlap with the inserting protrusion in up and down directions such that the pin-detachment guide member 300 is screw coupled to the inserting protrusion 400 while the pin-detachment guide member 300 is sequentially introduced into the upper and lower wings, and the pin-detachment guide member, which is introduced into insides of the inserting member and the inserting protrusion 400, is separated by a continuous rotation operation of a user, so that a part thereof remains in the inserting part C and the inserting protrusion. Thus, the upper and lower wings of the inserting part are restricted to each other so that the side shield is coupled to the temple of glasses.

(23) In this case, the inserting protrusion 400, which is means for screw coupling the pin-detachment guide member 300 of the present invention in order to couple the side shield B to the temple A, includes a coupling hole having a screw thread formed on the inside surface thereof. A diameter of the coupling hole is less than that of the lower inserting part 321.

(24) FIGS. 6 to 8 are schematic views illustrating states of using the pin-detachment guide member according to an embodiment of the present invention.

(25) Hereinafter, the embodiment of the pin-detachment guide member 300 will be described with reference to the drawings.

(26) First, when the pin-detachment guide member 300 is introduced into the upper wing D of the inserting member C, the upper inserting part 322 is placed in the upper wing D, the lower inserting part 321 is placed in the lower wing E and the screw part is placed in the inserting protrusion 400 which is interposed between the upper and lower wings D and E, so that the side shield is coupled to the temple. In this case, the lower inserting part 321 passes through the screw thread of the inserting protrusion to arrive at the lower wing E, so that the pin-detachment guide member 300 is coupled and fixed to the inserting member C of the side shield while the screw part 323 is engaged with the screw thread of the inserting protrusion 400.

(27) Then, as the knob 310 is continuously rotated, the detachable member 320 is no longer rotated at the location at which the screw thread does not exist. The continuous rotation of the knob 310 induces the knob 310 to be rotated alone in a state that the detachable member 320 is fixed so that the knob 310 is separated due to inter-torsion.

(28) Meanwhile, the operating groove 324 may be further provided on a bottom surface of the lower inserting part 321 in order to remove the detachable member 320 previously coupled. The operating groove 324 may have an I shape or a cross shape.

(29) The operating groove 324 signifies a groove into which a tool such as a conventional driver may be coupled. Thus, the previously assembled detachable member may be more easily removed from the side shield by using the operating groove.

(30) FIG. 9 is a perspective view showing a pin-detachment guide member for fixing a side shield according to another embodiment of the present invention. FIG. 10 is a view illustrating a state of using the pin-detachment guide member of FIG. 9.

(31) It can be confirmed from FIGS. 9 and 10 in which another embodiment of the pin-detachment guide member is depicted that the knob is enabled to be omitted.

(32) That is, the pin-detachment guide member 300 of the present invention is introduced into an inner space of the upper and lower wings D and E which are disposed to overlap with each other in up and down directions of the inserting protrusion such that the pin-detachment guide member 300 is screw coupled to the inserting protrusion 400. To this end, although any reference numerals are not assigned, an operating box having the same type as that of the operating groove 324 may be further provided.

(33) Such a configuration brings out the technical characteristics of the present invention in which the temple A and the side shield B are enabled to be fixed to or separated from each other by using the pin-detachment guide member 300, and allows the intended goal to be achieved in the state of excluding the knob 310 so that the configuration may be operated as another advantage.

(34) According to the side shield fixing structure having a pin-detachment guide member of the present invention, due to the detachable structure of the knob and the detachable member, the side shield can be firmly fixed to the temple of glasses and when the knob is twisted, the detachable member is separated from the knob, so that the separated detachable member remains in the state that the detachable member is introduced into the inserting member of the side shield and the inserting protrusion, so the side shield can be more conveniently fixed to the temple of glasses. Specifically, according to the present invention, the coupled detachable member for fixing the side shield is detachable without difficulty due to the operating groove provided on the bottom surface of the detachable member. That is, the detachable member can be quickly detached by using the operating groove with a separated tool (such as a driver).

(35) As a result, since the pin-detachment guide member for fixing aside shield according to the present invention allows the side shield to be conveniently installed to the temple and enables the detachable member previously installed to be separated, the pin-detachment guide member allows the side shield to be conveniently installed to glasses and the detachable member of a screw pin type, which is an object used to fix the side shield, can be more removed in a more easy scheme.

(36) Although an exemplary embodiment of the present invention has been described for illustrative purposes with reference to the embodiments depicted in the drawings, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
