Description

Description SIDE SHIELD ATTACHING STRUCTURE OF EYE-GLASSES

Technical Field

[1] The present invention relates to a side shield attaching structure of glasses, which can fix a side shield for protecting eyes on hinges connecting temples of the glasses to a frame of the glasses. More particularly, the present invention relates a structure that can easy attach or detach the side shield to the temples of the glasses through a simple process. The present invention relates to a structure that can easily assemble or disassemble auxiliary lenses protecting lenses of the glasses on or from the side shield. Background Art

[2] Generally, in order to prevent injury of eyes of a worker by fragments or flame during, for example, welding in industry, the worker wears industrial glasses.

[3] A side shield attaching structure of glasses is disclosed in a utility model application

No. 1999-0002199. That is, as shown in Figs. 1 and 2, a side shield 5 is attached to hinges (only one is shown) 4 connecting left and right temples (only the right temple is shown) 2 of the glasses 1 to a frame 3 of the glasses 1. The side shield 5 has an attaching surface 6 extending in an axial direction. The temple 2 of the glasses 1 is partly fitted in the attaching surface 6 to be restricted in movement in a width direction. The side shield 5 further has a front surface enlarged to enclose the frame 3. Pin holes 7 and T die formed through the attaching surface 6 and the temple 2. A fixing pin 8 is inserted into the pin holes 7 and 7' to prevent the side shield 5 from moving in the axial direction.

[4] Meanwhile, the fixing pin 8 has a main body 9, a pin head 10 formed on a first end of the main body 9, an elastic portion 12 formed by a cutting portion 11 formed to a predetermined portion, a dome portion 13 formed on an end of the elastic portion 12, and a hook step 14 formed on a bottom of the dome portion 13.

[5] When the fixing pin 12 is forcedly pushed into the pin holes 7 and 7' that are aligned, the elastic portion 12 and the dome portion 13 are shrunk by the cutting portion 11 to sequentially pass through the pin hole 7 of the side shield 5 and the pin hole 7' of the temple 2. As a result, outer circumferences of the main body 9 and the elastic portion 12 closely contact inner circumferences of the pin holes 7 and 7' When the dome portion 13 completely passes through the pin hole T of the temple 2, the elastic portion 12 and the dome portion 13 are returned to their wide positions and the hook step 14 is hooked on the inner surface of the temple 2. Therefore, the side shield 2 is fixed on the temple 2.

[6] According to the prior art side shield attaching structure of the glasses, the fixing pin having the elastic portion is shrink-fitted in the pin holes formed through the temple and the side shield. In this case, in order to disassemble the temples from the side shield to replace or repair the glasses, a tool for removing the fixing pin is required. That is, it is not easy to remove the fixing pin. Furthermore, since the side shield is coupled to the temples, it cannot protect the front portion of the glasses from the fragments or foreign substances and thus the lenses of the glasses may be damaged. As a result, the working efficiency is deteriorated.

[7] Furthermore, since the temple is attached only in the axial direction by a step formed on the attaching surface of the side shield, the coupling cannot be quickly realized. Disclosure of Invention Technical Problem

[13] The hook unit may include a wedge groove formed on the cutting portion and a wedge-type rail 33 formed on the coupling portion that allows the coupling member to be coupled o the wedge groove and to move in a vertical direction but not in a ho- rizontal direction.

[14] The coupling unit may include a rectangular cutting portion formed on the temple coupling portion and a coupling member having a first end rotatably coupled to the cutting portion and a second end provided with a fixing pin that can be fixedly inserted in a notch portion when the temple coupling portion is coupled to a temple.

[15] In order to maintain a uniform coupling position of the temple coupling portion and the temple when the temple is coupled to the temple coupling portion of the side shield, a protrusion and a groove in which the protrusion is inserted may be respectively provided on the temple and the temple coupling portion.

[16] Dual flanges for coupling a sub-lens may be formed on the front portion of the side shield.

[17] A plurality of protrusions may be formed in a groove defined between the dual flanges and notches in which the protrusions are fitted are formed on an edge of the sub-lens.

[18] The side shield attaching structure may further include a connecting member for interconnecting a pair of the sub-lenses, wherein the connecting member is provided at opposite ends thereof with coupling grooves in which the respective sub-lenses are detachable fitted so that the sub-lenses can be detachably coupled to the side shields.

[50] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[51] Referring to Figs. 3 through 7, a side shield attaching structure of an embodiment of the present invention includes a notch portion (b) formed on an inner surface of a temple 10 and a coupling unit formed on a temple coupling portion 21 of the side shield, fixing the side shield 20 to the temple 10 by being fitted in the notch portion (b), and separating the side shield 20 from the temple 10 by being removed from the notch portion (b).

[52] The coupling unit includes a cutting portion (a) that is formed on the temple coupling portion 21 that is aligned with the notch portion (b) and expose the notch portion b to an external side when the temple coupling portion 21 is coupled to the temple 10 and a coupling member 30 that is provided with a fixing pin 31 inserted into the notch portion (b) through the cutting portion (a) and partly hooked on the cutting portion (a) to fix the side shield 20 to the temple 10.

[53] That is, since the temple 10 is inserted in the temple coupling portion 21 of the side shield 20 and moves in an axial direction, the notch portion (b) of the temple 10 is exposed through the cutting portion (a) of the side shield 20. Therefore, when the coupling member 30 is inserted through the cutting portion (a), the fixing pin 31 of the coupling member 30 is fitted into the notch portion (b) of the temple 10, thereby fixing the temple coupling portion by restricting the movement of the side shield 20 in the lateral and axial direction.

[54] A curved groove 34 is provided on the cutting portion (a) of the side shield 20. The fixing pin 31 is inserted in the curved groove 34. A hook unit is formed between the cutting portion (a) and the coupling member 30 to prevent the coupling member 30 from being removed in a horizontal direction but to allow the coupling member 30 to move in a vertical direction.

[55] The hook unit includes a wedge groove 35 formed on the cutting portion (a) and a wedge-type rail 33 formed on the coupling portion 30 that allows the coupling member 30 to be coupled o the wedge groove 35 and to move in a vertical direction but not in a horizontal direction.

[56] That is, when the rail 33 of the coupling member 30 is inserted to be coupled in the wedge groove 35 at an upper portion of the cutting portion (a) of the side shield 20, the coupling member 30 can move in a vertical direction but does not comes out in the horizontal direction.

[57] Particularly, a wing 37 is formed on each of upper and lower portions of the coupling member 30. When the coupling member 30 is inserted into the cutting portion (a), the wings 37 of the coupling member 30 are slightly hooked on the upper or under surfaces of the side shield 20 and thus the coupling member 30 does not easily come out.

[58] In order to allow the temple 10 can be quickly coupled to the temple coupling portion

21 of the side shield 20 in the axial and lateral directions, an inside portion of the temple coupling portion 21 may be opened so that the temple 10 can be inserted therein.

[59] In operation, as shown in Fig. 3, the temple 10 is pushed into the side shield 20 at a rear portion of the side shield 20 such that the notch portion (b) of the temple 10 is aligned with the cutting portion (a) of the side shield 20.

[60] When the notch portion (b) is aligned with the cutting portion (b), the fixing pin 31 of the coupling member 30 is inserted in the curved groove 34 and pushed downward in a state where the coupling member 30 is located on the top surface of the side shield 20.

[61] When the fixing pin 31 of the coupling member 30 is inserted into the curved groove

34, the coupling member 30 is pushed downward such that the coupling member 30 is inserted into the cutting portion (a). Therefore, as described above, when the coupling member 30 is inserted into the cutting portion (a), the coupling member 30 is engaged with the notch portion (b) to fix the side shield 20.

[62] That is, when the coupling member 30 is inserted into the cutting portion (a) in a state where the temple 10 is coupled to the side shield 20, the side shield 20 is securely fixed. By simply removing the coupling member 30, the side shield 20 can be separated from the temple 10. That is, the coupling and separating of the side shield 20 to and from the glasses can be easily achieved.

[63] Figs. 8 through 12 show another embodiment of the present invention. A coupling unit of this embodiment includes a rectangular cutting portion (a¹) formed on a temple coupling portion 21 and a coupling member 30' having a first end rotatably coupled to the cutting portion (a¹) and a second end provided with a fixing pin 31' that can be fixedly inserted in a notch portion (b¹) when the temple coupling portion 21 is coupled to a temple 10.

[64] That is, the coupling member 30' is rotatably coupled to the temple coupling portion

21 of the side shield 20 by a pivot pin 32. When the coupling member 30' rotates, the fixing pin 31' formed on the coupling member 30' is fitted in the notch portion (b¹).

[65] The cutting portion (a¹) of the temple coupling portion 21 is provided in the form of a hole in which the coupling member 30' can be inserted. A hole 38 through which a lower end of the fixing pin 31' of the coupling member 30' can pass is formed on an undersurface of the cutting portion (a¹). The coupling member 30' is formed in an arc- shape having a predetermined angle with reference to the first end of the coupling member 30' through which the pivot pin 32 passes. The fixing pin 31' concentrically protrude from a side surface of the coupling member 30'.

[66] When the temple 10 is inserted in the temple coupling portion 21 of the side shield

20 and pushed in an axial direction, the notch portion (b¹) of the temple 10 is exposed through the cutting portion (a¹). In this state, when the coupling member 30' rotates about the pivot pin 32, the coupling member 30' closely contacts an inside of the temple 10 and the fixing pin 31 of the coupling member 30' is inserted into the notch portion (b¹) of the temple 10. At this point, the lower end of the coupling member 30' is fitted in the hole 38 and thus the movement of the side shield in the axial and lateral directions is restricted.

[67] As described above, the coupling a separating of the side shield 20 to and from the temple 10 can be easily realized by the coupling member 30' that moves through the pivotal motion. That is, by simply pivoting the coupling member 30' the side shield 20 can be easily mounted on or separated from the glasses.

[68] Figs. 13 through 17 show another embodiment of the present invention. In this embodiment, in order to maintain a uniform coupling position of a temple coupling portion 21 and a temple 10 when the temple 10 is coupled to the temple coupling portion 21 of the side shield 20, a protrusion 11 and a groove 22 are respectively provided on the temple 10 and the temple coupling portion 21. The protrusion 11 is engaged with the groove 22.

[69] That is, when the temple 10 is inserted into the side shield 20, the protrusion 11 is fitted in the groove 22 and a coupling member 30" pivotally coupled to a cutting portion (a) formed on a middle portion of the temple coupling portion 21 closely contacts an inner surface of the temple 10 so that the movement of the side shield 20 in the axial and lateral directions relative to the temple 10 is restricted.

[70] Curved flanges 23 for fixing a sub-lens are formed on a front portion of the side shield 20. An edge of the sub-lens 40 is fixedly fitted in a groove defined between the curved flanges 23. A plurality of protrusions 24 are formed in the groove defined between the curved flanges 23. The sub-lens 40 is provided at the edge thereof with a plurality of notches 41 in which the protrusions 24 formed in the groove are respectively inserted. When the protrusion 24 is engaged with the notches 41, the sub- lens 40 can be more securely fixed on the flanges 23.

[71] As shown in Figs. 18 through 20, a connecting member 50 is provided to interconnect a pair of the sub-lenses 40. The connecting member 50 is provided at opposite ends thereof with curved coupling grooves 52 in which the respective sub- lenses 40 are fitted so that the sub-lenses 40 coupled to the side shields 20 can be more stably secured.

[72] A protrusion 51 is formed in only one of the coupling grooves 52 and a notch 41' in which the protrusion 51 is fitted is formed on only one of the sub-lenses 40.

[73] That is, a first side of the connecting member 50 is provided with the coupling groove 52 and the protrusion 51 while the second side is provided on only one side of the connecting member 50 while a second side of the connecting member 50 is provided with only the coupling groove 52. In addition, only one of the sub-lenses 40 is provided with the notch 41' Therefore, the protrusion 51 formed on the first side of the connecting member 50 is fitted in the first coupling groove 52 and coupled to the notch 41' while the other sub-lens 40 is simply fitted in the second coupling groove 52.

[74] Meanwhile, the notch 41' in which the protrusion 51 in the coupling groove 52 is fitted have an inlet larger than an inside passage so that the protrusion 51 is not easily separated from the notch 41'

[75] Needless to say, as shown in Fig. 21, the protrusion 11 may be formed on the temple coupling portion 21 of the side shield 20 and the groove 22 may be formed on the temple 10. This case results in the same effect.

[76] Further, as shown in Fig. 22, the pair of sub-lenses 40 may be integrally formed with each other. The integrated sub-lenses are provided at an edge with notches 41 in which protrusions 24 formed between the flanges 23 are tightly fitted, thereby securely fixing the sub-lenses 40.

[77] It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
