Description:
FIELD OF THE INVENTION 
     This invention relates to a cap with binoculars suitable for watching sports and the likes, and more particularly, to a double functioning cap with binoculars that can effectively perform both functions of a cap and binoculars. 
     BACKGROUND OF THE INVENTION 
     Since binoculars are usually carried by hand, they are very inconvenient to continue to use and carry for many hours. 
     SUMMARY OF THE INVENTION 
     It is, therefore, an object of the present invention to provide a cap with binoculars which can perform both the functions of a cap and binoculars. 
     A further object of the present invention is to provide a cap with light-weight binoculars which can be conveniently used and carried for many hours. 
     In accomplishing these and other objects, according to the present invention, there is provided a cap with binoculars which includes a first member and a second member thereof. The first member includes in it a binoculars receiving portion formed integrally on the visor, a latch forming portion and pin holes. The second member includes a band, a a supporting protrusion and pin holes. The first member is attached to the second member by means of pin means. The binoculars are mounted within the binoculars receiving portion. The first member can be shifted from the normal position to a down-position by swinging the visor downward. Thus, both the functions of a cap and binoculars are easily accomplished.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIGS. 1, 2 and 3, a cap according to the invention has a first member(1) and a second member(6) thereof. The first member(1) includes a latch receiving groove(10) formed in the center of the vertical semicircular portion thereof, a visor(5), and a binoculars receiving portion(2) formed integrally on the visor(5). The second member(6) includes a resilient cotton band(9) attached to the second member(6) by means of connecting hooks(8) and suitable hook means formed in the inner surface of the vertical semicircular portion thereof. The first member(1) is attached to the second member(6) by means of connecting pins(7). Thus, the first member(1) can be moved either down or upward with respect to the second member(6). 
     On the other hand, the binoculars receiving portion(2) is formed integrally on the visor(5), as described above and the upper surface of the portion(2) has an opening(22) for actuating an adjusting knob(4). Also, protecting glass(3) is mounted on the front surface of the portion(2). Though will be described hereinafter, such light-weight binoculars are inserted within the portion(2) and are mounted by means of a suitable holding means such as designated refrence number(19), as shown in FIG. 3. It is to be noted that when binoculars are heavy weighted, they are very inconvenient to use for various purposes. 
     FIG. 5 illustrates the light-weight binoculars. Left and right objective lens cases(14L, 14R) can be telescopically inserted into left and right eyepiece cases(11L, 11R), respectively. The eyepiece and objective cases have an eyepiece(13) and an objective lens(12), respectively, and the cases(11L, 11R; 14L, 14R) are made of light-weight materials such as plastics and rubber. 
     A right front supporting member(15R) and a left front supporting member(15L) which are connected to the objective lens cases (14R, 14L) respectively, are constructed so that the members(15L, 15R) can be folded towards each other about an outer-threaded rod(16). In front of the supporting members(15L, 15R), the adjusting knob(4) connected to the rod(16) is provided. Therefore, the left and right front supporting members(15L, 15R) can be folded about the axis of the rod(16) and the adjusting knob(4). 
     In like manner, between the left and right eyepiece cases, a right rear supporting member(18R) and a left rear supporting member(18L) which are connected to the eyepiece cases(11R, 11L) respectively, are constructed so that the members(18L, 18R) can be folded towards each other about an inner-threaded cylinder(17) (see FIG. 5(b)). 
     The inner-threaded cylinder(17) and the outer-threaded rod(16) which are formed between the front and rear supporting members, are in mesh with each other. Also the objective lens cases(14L, 14R) are inserted into the eyepiece cases(11L, 11R). Therefore, when actuacting the adjusting knob(4), the eyepiece and objective lens cases(14L, 14R; 11L, 11R) can be either withdrawn or extended so as to achieve an optimal focus. In addition, the eyepiece cases(11L, 11R) can be folded about the axis of the cylinder(17), the rod(16) and the adjusting knob(4) (see FIG. 5(b)). Thus, the distance between the left and right lenses of the binoculars can be adjusted according to the user&#39;s eye distance by folding the above said apparatuses. As seen from the above, construction of a cap with light-weight binoculars according to the invention can be easily accomplished. 
     Binoculars, as illustrated above, are mounted on the cap so that the upper portion of the inner-threaded cylinder(17) is mounted to the binoculars receiving portion(2) by means of holding means(19) as illustrated in FIG.3(a). 
     FIG. 4(a) shows when this invention is used as an ordinary cap. When a user wants to use the binoculars along with the cap, as illustrated FIG. 4(b), the user simply needs to pull down the visor(5) and fold the left and right eyepiece cases to adjust them to the distance desired, and focus the lenses with the adjusting knob(4). Similary, to return to a cap only, the user simply pushes the visor(5) up ward. Then, the latch(20) within the latch receiving groove(10) is caught on the supporting protrusion(21) as illustrated in FIG. 3(b). 
     This invention relates to a double functioning cap with the light-weight binoculars. When the total weight thereof is further reduced, not only will it be more idealistic to use both as a cap and binoculars, but also continuous uses of such binoculars for long hours are possible as well. 
     While there has been described what is at present considered to be preferred embodiment of the invention, it will be understood that various modifications may be made therein, and it is intended to cover in the appended claim all such modifications as fall within the true spirit and scope of the invention.
