Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a cap with a selective viewing angle; and, more particularly, to a cap capable of securing a selective viewing angle, which can selectively secure a viewing angle only with respect to a specific object by a bent part provided at a brim.
2. Description of Related Art
As well-known in the art, in recent years, due to ozone layer destruction caused by environmental pollution or the like, UV (ultraviolet) rays of the sunlight are not properly absorbed in the ozone layer but great amounts of UV rays are transmitted to the ground. When a human body is exposed to the UV rays for a long time, this decreases the vision of a human eye or causes various damages, such as pigmentation of the facial skin, chloasma, burn, skin cancer and so on.
Therefore, in order to prevent decreased vision or damages to the facial skin, caps for outdoor activities generally have a brim to protect the face and field of view from UV rays of the sunlight.
As illustrated in FIG. 1, a conventional cap 2 is comprised of a cap body 4 elastically inserted to and removed from the head portion of a human body and a brim 6 of which one end is sewn and coupled to the edge of the front lower end of the cap body 4, the brim 6 consisting of an inner extended part 6 a with a bent shape and an outer extended part 6 b.
At this time, the brim 6 is coupled to the cap body 4 in a direction horizontal to the ground surface, and thus, the irradiation angle of the sunlight depending on a season is able to cover most parts of the upper front side of a user's face even within a variation range.
Meanwhile, while such a conventional cap 2 has the purpose of blocking UV rays irradiated from the sunlight, players play a game wearing the cap 2 during a sports match taking place in a playing field in order to prevent players' hair from being blown off and avoid sports behaviors from being interfered by the sunlight.
Representative field sports are baseball and golf. As field games of these two events include the procedure of having to watch a ball in the air, the players have to carefully watch a ball in the air while avoiding the interference from the sunlight.
Especially, as illustrated in FIG. 3, a human eye is supposed to sense the distance with an object by an optical angle formed between both eyes and the object by focusing on the distance with the object by both eyes. That is, the optical angle becomes larger as the distance with the object is closer (θ2), rather than as the distance between both eyes and the object is farther (θ1). Thus, when the distance with the object becomes closer, the distance with the object can be sensed more precisely.
Therefore, if a ball is high in games like baseball, the optical angle is very small, and thus the player sensuously captures a drop point. On the other hand, if the optical angle becomes greater, the player can capture the drop point of the ball more precisely while actually checking it with naked eyes. However, due to acceleration generated when the ball performs a free fall movement, acceleration per second rapidly increases as the ball is nearer to the final drop point, rather than when the ball is in a flying state.
Consequently, as the speed of the ball just before fielders catch the ball with a glove becomes the highest speed, the fielders require a good concentration in order to catch the falling ball, and should not be disturbed under any environment.
However, in the daytime, in case where fielders catch a falling ball or golfers take a long shot by a drive, if they watch the position of a flying ball 8 with both eyes, it is often the case that they are disturbed by the sunlight 10, as shown in FIG. 2. That is, although players put on the cap 2 in order to minimize the interference of the sunlight 10, it is often the case that the scenery actually seen from the eyes of the players is interfered by the sunlight 10, as depicted in FIG. 2.
Accordingly, although the players have attempted to make out the object from the sunlight by putting on sunglasses, there is almost no effect because it is difficult to clearly make out the object desired to be recognized once they actually put on sunglasses and the sunlight cannot be completely shut out from their view.

SUMMARY OF THE INVENTION

The present invention has been made in view of the above drawbacks, and it is, therefore, an object of the present invention to provide a cap capable of securing a selective viewing angle, which can minimize interference of the sunlight when players playing a game outdoors put on sunglasses by selectively securing only a viewing angle with respect to a specific object as some areas of the object captured within the viewing angle are hidden by a bent part of the cap if the distance with the object is captured with both eyes.
In accordance with the present, there is provided a cap with a selective viewing angle, comprising: a cap body 22 elastically inserted to and removed from the head portion of a human body; and a brim 24 of which one end is sewn and coupled to the edge of the front lower end of the cap body 24, wherein the brim 24 has a bent part 26 formed on a predetermined part of the center thereof, and is coupled to the cap body 22, so that a view blocking area 28 for screening parts of the field of view when putting on the cap is formed by the bent part 26 to thus selectively secure a field of view only with respect to a specific object

DESCRIPTION OF SPECIFIC EMBODIMENTS

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 4 is a perspective view illustrating a cap capable of securing a selective viewing angle according to a first embodiment of the present invention, FIG. 5 is a front view illustrating the cap capable of securing a selective viewing angle according to the first embodiment of the present invention, and FIG. 6 is a view illustrating the field of view shown by the cap capable of securing a selective viewing angle according to the first embodiment of the present invention.
Referring to these drawings, the cap 20 capable of securing a selective viewing angle according to the first embodiment of the present invention is a cap, which can minimize interference of the sunlight when players playing a game outdoors put on sunglasses by selectively securing only a viewing angle with respect to a specific object as some areas of the object captured within the viewing angle are hidden by a bent part of the cap if the distance with the object is captured with both eyes.
For the above purpose, the cap 20 capable of securing a selective viewing angle according to the first embodiment of the present invention is comprised of a cap body 22 elastically inserted to and removed from the head portion of a human body and a brim 24 of which one end is sewn and coupled to the edge of the front lower end of the cap body 22, the brim 24 consisting of an inner extended part 24 a with a bent shape and an outer extended part 24 b.
At this time, as the brim 24 is coupled to the cap body 22 in a direction horizontal to the ground surface, the irradiation angle of the sunlight depending on a season is able to cover most parts of the upper front side of a user's face even within a variation range.
Especially, the brim 24 of the cap 20 capable of securing a selective viewing angle according to the first embodiment of the present invention is coupled to the cap body 22 in a wave shape. In other words, the brim 24 is coupled to the cap body 22, by means of being provided with a bent part 26 bent in a V-shape on a predetermined portion of the center thereof.
Therefore, the brim 24 is configured so as not to be easily made flat even if an external force is applied to the bent part 26 formed on the brim 24, and once the cap is put on, a view blocking area 28 for screening parts of the field of view is formed by the bent part 26, as shown in FIG. 5.
The view blocking area 28 is able to selectively secure a viewing angle according to a direction in which the brim 24 faces. That is, as for the brim 6 (see FIG. 1) with no view blocking area 28, a viewing angle is secured with respect to every object according to the direction of the brim 6 as illustrated in FIG. 2. On the other hand, the brim 24 of the present invention has the view blocking area 28 formed by the bent part 26 formed at a predetermined part of the center, and is able to exclude the sun from the viewing angle but secure only a ball 8 in the air within the range of the viewing angle by the view blocking area 28 as illustrated in FIG. 6.
Thus, baseball players, such as fielders and pitchers, or golfers can clearly observe a flying ball without interference of the sunlight.
Hereinafter, a second embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 7 is a perspective view illustrating the outer shape of a cap capable of securing a selective viewing angle according to a second embodiment of the present invention, FIG. 8 is an exploded perspective view illustrating a coupled state of a view selection plate provided on the cap capable of securing a selective viewing angle according to the second embodiment of the present invention, and FIG. 9 is a state view illustrating an operating state of the view selection plate mounted on the cap capable of securing a selective viewing angle according to the second embodiment of the present invention.
Referring to these drawings, the cap 2′ capable of securing a selective viewing angle according to the second embodiment of the present invention is based on the same principle as the first embodiment of the present invention, but it is a cap for selectively securing a field of view by attaching a view selection plate 30 to the bottom surface of the front end of a general brim 6 without forming the view blocking area 28 by the bent part 26.
In other words, the view selection plate 30 in the present embodiment is a thin square plate which can selectively secure a field of view only with respect to a specific object by blocking parts of the field of view in the same way as the view blocking area 28 generated by the bent part 26 in the first embodiment.
For this, the cap 2′ capable of securing a selective viewing angle according to the second embodiment of the present invention has a cap body 4 inserted to and removed from the top portion of one's head like a general cap, and a brim 6 coupled to the front lower end of the cap body 4.
In addition, the view selection plate 30 is attached to the bottom surface of the front end of the brim 6 at a right angle to the brim 6. To couple the view selection plate 30 to the bottom surface of the brim 6, holders 34 are provided on the bottom surface of the brim 6, which are attached spaced at a predetermined distance between them and have coupling recesses formed on their facing inner sides.
The holders 34 may be attached to the front lower portion of the brim 6 by an adhesive or double-faced tape, and may be attached by sewing in some cases.
Further, coupling projections 30 a coupled to the coupling recesses of the holders 34 are formed on both upper ends of the view selection plate 30, and springs 36 are interposed, which provide an elastic restoring force by making one ends of the coupling projections 30 a coupled to the inside of the coupling recesses of the holders 34 and the other ends thereof coupled to the coupling projections 30 a.
Thus, according to the user's intention, the view selection plate 30 may be folded to be tightly contacted with the bottom surface of the brim 6 or unfolded at a right angle to the brim 6.
Preferably, triangular projections (not shown) are formed in a longitudinal direction on the outer peripheries of the coupling projections 30 a formed on the view selection plate 30, and triangular recesses (not shown) corresponding to the triangular projections are formed on a predetermined part of the inner peripheries of the coupling recesses formed at one sides of the holders 34. By doing so, a restoring force operates to always make the view selection plate 30 spread at a right angle with respect to the brim 6. In this state, when the view selection plate 30 is forcibly rotated by a user's external force, the triangular projections formed on the coupling projections 30 a are inserted by force fit into the triangular projections formed on the inner peripheries of the coupling recesses so that the view selection plate 30 can overcome the restoring force of the spring 36.
Meanwhile the cap capable of securing a selective viewing angle according to the embodiments of the present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the gist of the present invention.
As discussed above, the cap capable of securing a selective viewing angle according to the present invention has the advantage of precisely recognizing an object since the sunlight is avoided and only a field of view with respect to a specific object is secured by being provided with a brim having a bent part and allowing a user to select an object desired to secure its field of view through a view blocking area formed by the bent part. Such a cap is very effective because it allows baseball players and golfers to clearly make out a ball in the air in daytime games and nighttime games with night lamps switched on.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
