GLASSES FOR USE WITH A CAP Technical Field The present invention relates to glasses for use with a cap such as sunglasses for shading the eyes, which is capable of being easily installed to the cap having a visor, and being folded or lifted up or down at any angle as required by optionally controlling the angle of the glasses installed to the visor of the cap.

Background of Art In general, a cap for protecting a head from the sun and so on is mostly provided with a visor at the forepart thereof, which shields one's face from direct rays of the sun. In addition to the visor, sunglasses or glasses are separately put on for protecting one's eyesight from the sunlight.

Also, a cap fixedly installed with eye-protecting glasses has been worn for carrying out welding and so on. However, the above eye- protecting glasses only have two functions of lifting up and down at the forepart of the cap.

Therefore, when a user wants to put on the cap and the glasses simultaneously, it is very inconvenient to wear and keep them since they have to be separately carried or put on. In case of providing the above cap with the eye-protecting glasses, it causes trouble that the eye-protecting glasses cannot be open at a suitable angle since they have only two functions of completely turning up and down. Furthermore, if a user intends to slightly open the eye-protecting glasses at a middle position to see an object while the eyes are being protected, it is very troublesome and inconvenient to use the cap since the above eye-protecting glasses should be held with one hand.

Moreover, if the eye-protecting glasses fixed to the cap are damaged, the eye-protecting glasses and cap have to be abandoned altogether because the said glasses cannot be easily replaced alone. Additionally,

since the above glasses or eye-protecting glasses installed to the cap cannot be replaced freely in accordance with the type of the cap, the cap should be fixed with the same glasses or eye-protecting glasses at any time such that the user becomes easily tired of the glasses.

Disclosure of the Invention The present invention is contrived to solve the above-described conventional problems. Therefore, an object of the present invention is to provide glasses for use with a cap, such as sunglasses, which can be easily and conveniently installed to the cap having a visor, and can be folded or lifted up and down at any angle as required by optionally controlling the angle of the glasses while a user is putting on the cap.

Another object of the present invention is to provide the glasses manufactured in one body without a separate frame, in order to shorten the manufacturing process and reduce the manufacturing cost.

To achieve the above objects, the present invention is to provide glasses for use with a cap installed to the cap having a visor, that includes glasses which have gear-fixing grooves on both upper end portions and which are formed of transparent material in one body by molding. Also, the present invention comprises gears each of which is consisting of a glasses fixing member inserted to be fixed into the gear fixing grooves formed on both upper ends of the glasses, and a gear member formed of cylindrical gear which is fixed on the upper part of the glasses fixing member and which has horizontal gear teeth and a fixing-shaft inserting hole in the center. Also included as parts are clips, each of which has a clip member bound to or removed from the desired position of visor of the cap, a stopper inserting part at the lower end of the clip member for inserting a stopper that engages with the teeth of the gear member and a spring that gives an elastic power to the stopper, and shaft receiving members formed at both sides of the entrance of the stopper inserting part for fixing the gear. Here, the stopper is inserted into the stopper inserting part of the clip for controlling the motion of the gear, and the spring is

mounted in the inside of the stopper for applying elasticity to the stoppers.

In addition to these, there are provided fixing shafts in the form of pins for fixing the gears to the shaft receiving members of the clips.

Best mode for carrying our the Invention Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

To begin with, FIG. 1 shows one embodiment of glasses for use with a cap according to the present invention, in which the glasses for use with the cap is clipped to a visor 2 of a cap 1. The glasses for use with a cap can be installed to every cap having a visor.

The glasses for use with a cap include glasses 3 for shading the eyes, gears 5 brought into meshing engagement with both ends of the glasses 3 for controlling an angle of the glasses, and clips 6 internally mounted with stoppers 7 coupled with the gears 5 to control the angle of the glasses.

First, the glasses 3 are formed by molding in one body using a transparent substance such as a transparent plastic which is not easily damaged from an external shock, and formed with gear fixing grooves 4 for inserting and fixing the gears which will be described later. At this time, the glasses 3 may be coated with a sun block material for the purpose of shading the eyes from ultraviolet rays or be coated with a variety of colors in terms of the sense of beauty.

Next, the gears 5, each of which consists of a cylindrical gear member with a plurality of teeth and a glasses fixing member formed to the lower plane of the gear member in a body. At this time, a thruhole is formed in the center of the gear member to be capable of being inserted with a fixing shaft. The glasses fixing member is inserted and fixed into the gear fixing groove 4 formed on the upper end of the glasses, and the glasses fixing member can be employed in or removed from the gear fixing groove at need.

Also, the glasses fixing member of the gear 5 may be formed as a plate form, and at least one screw fitting hole is formed in the plate to fix the gear 5 to the upper end of the glasses by means of a screw.

Furthermore, because the glasses 3 and the gears 5 are formed of the same material by molding, they may be manufactured in one body.

In addition, a gear 13 having projections 14 in one body, which are

inserted and fixed into shaft receiving members to be described later may be formed as shown in FIG. 4 without forming the fixing-shaft inserting hole in the gear member of the gear 5. Thereby, the gear can be coupled to the shaft receiving members without requiring the fixing shaft to reduce the number of parts.

Then, a clip 6 includes a clip member for being joined to the visor 2 of a cap, a stopper inserting part which is formed at the lower end of the clip member and inserted with a stopper 7 and a spring 8 for supplying elasticity to the stopper 7, and the shaft-receiving members 9 for insertedly receiving fixing shaft 10, which are formed on both sides of the entrance of the stopper inserting part for fixing the gear 5. At this time, the stopper 7 is shaped as a rectangular plate having elasticity by the spring 8 to be enough to fix the gear-teeth formed along the gear member of the gear 5 which will be coupled to the shaft receiving members 9. By doing so, once the gear 5 is rotated, the stopper 7 retracts by means of the gear-teeth to be engaged into the next dent of the gear-teeth by the elasticity supplied from the spring 8 such that the stopper 7 can block the gear 5 from rotating of itself.

Also, the stopper 7 may be constructed as stoppers 11 and 12 having elastic members 11'and 12'of various forms in place of the springs at the rear ends of the stoppers as shown in FIG. 3, for reducing the number of parts and shortening the assembly process.

According to the present invention as described above, when a cap 1 is formed with a visor 2 which is furnished with glasses 3 such as sunglasses or eye-protecting glasses, the glasses 3 are brought into meshing engagement with gears fixed to the shaft receiving members of clips 6 provided to both ends of the glasses 3. Thereafter, the glasses 3 are lifted up and down as shown in FIG. 6. Once the glasses 3 are held to be lowered, the gear members of the gears become in contact with stoppers 7 combined with the clips 6 by the elasticity of springs 8. Thus, the stoppers 7 are in a state of being hooked on any one among the plurality of gear- teeth formed on the gear members. When lowering down the glasses 3,

the gear-teeth of the gear members push backward the stoppers 7 having elasticity by the springs 8 while the gears 5 are rotated. Thereafter, when the stoppers 7 are placed into the next dent between the gear-teeth, the stoppers are fixed thereto and the angle of the glasses 3 is controlled such that the glasses 3 maintain the changed state intact unless they are pushed up and down by force. Consequently, the angle control of the glasses as required is completely accomplished.

When the glasses 3 for correcting the eyesight are furnished, the user can see the object exactly in terms of the user's eyesight. In case of the eye-protecting glasses or sunglasses for blocking the intense rays being furnished, the present invention further may have a function of blocking the rays.

Moreover, by forming the glasses 3 which have a protecting part 15 capable of shielding the nose in the center portion of the glasses as shown in FIG. 7, the ridge of nose can be protected from being hurt due to foreign substances.

FIGS. 8 and 9 show another embodiments of the glasses for use with a cap according to the present invention, in which, in place of the gear fixing grooves 4, male gear plates 16 having fixing-shaft inserting holes are formed on both ends of the glasses 3. Then, a plurality of projection- like male gears 18 are formed along a prescribed outer circumference of the male gear plates 16 by centering around the fixing-shaft inserting holes. Further to these, in place of the stopper inserting parts, female gear plates 17 are formed to the lower ends of the clips 6 to correspond to the male gear plates 16. Then, female gears 19 are formed along the inner side planes of the female gear plates 17 so as to receive the male gears 18 of the male gear plates 16 by centering around the fixing-shaft inserting holes. After this, fixing shafts 20 having one ends inserted with springs 21 are formed for fixedly connecting the gear plates 16 and 17, and the other ends of the fixing shafts are fixed by fixing plates 22.

In accordance with the glasses for use with a cap formed as above, when the glasses are held to be lifted up or down, the springs 21 of the

fixing shafts 20 contract while the male gears 18 of the male gear plates 16 become free from the female gears 19 of the female gear plates 17, and the springs 21 expand by the elasticity to make the male gears 18 inserted and fixed into the female gears 19 when the male gears 18 reach the following female gears 19 of the female gear plates 17.

Industrial Applicability According to the glasses for use with a cap constructed as described above, the glasses are furnished with the gears that can exactly and optionally control the angle of the glasses, and easily installed to or removed from the visor of the cap by means of the clips.

Furthermore, the glasses for use with a cap can be used just as desired in accordance with the user's need since the glasses may be easily installed to or removed from the visor of the cap.

In addition, although the glasses are installed to the cap, the angle of the glasses is conveniently and optionally controlled as required to make the glasses significantly easy to be used. Also, the angle controlled by means of the gears can be maintained as it is to make the angle unchanged in spite of the user's shaking his or her head during exercises. Moreover, in view of the glasses for use with a cap according to the present invention, the glasses and gears may be formed in a body without requiring a separate frame, thereby shortening the manufacturing process and reducing the cost.

While the present invention has been particularly shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be effected therein without departing from the spirit and scope of the invention as defined by the appended claims.
