Abstract

The cap has a first member 1 provided with a visor 5 having a portion 2 which receives a pair of binoculars, and a second member 6 for fitting around the head of the user. The members 1 and 6 are pivoted to one another at 7 so that, in use, the member 1 can be pivoted downwards to align the binoculars with the users eyes (Fig. 4b). Latching means 10 otherwise retain the member 1 in its upper position (Fig. 4a). The binoculars are light-weight and have telescopic lens cases (e.g. of plastics and rubber) adjustable by a rotatable wheel 4 which operates a threaded screw-and-cylinder adjuster (16, 17, Fig. 5a) <IMAGE>

Description

Cap with binoculars 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.

Since binoculars are usually carried by hand, they are very inconvenient to continue to use and carry for many hours.

According to the present invention, there is provided a cap with binoculars for performing both the functions of a cap and binoculars comprising; a first member of the cap including a binoculars receiving portion formed integrally on a visor, a latch receiving groove formed in the centre of a vertical semicircular portion thereof and pin holes fomred at left and right ends thereof, said binoculars receiving portion having protecting glass in front thereof and an opening on the upper surface thereof for providing access to an adjusting knob, a second member of the cap including a band connected to vertical semicircular portion thereof by means of hook means, a supporting protrusion formed in the outer surface of a vertical semicircular portion to be caught on the latching means in front thereof, and pin holes for connecting said second member to said first member, pin means for connecting said first member and said second member at both left and right ends, binoculars which are adapted to be mounted within the binoculars receiving portion by means of holding means, and are constructed so as to be adjusted according to the distance of the user's left and right eyes and to bring the lenses into a desired focus.

The first member can be shifted from its normal position to a down position by swinging the visor downward. Thus, both the functions of a cap and binoculars are easily accomplished.

These and other objects and advantages of the present invention are more fully specified in the following description with reference to the drawings in which; Figure 1 is a perspective view of an embodiment of the present invention; Figure 2 is a side elevation view, partly in cutaway, of the embodiment; Figure 3(a) is a perspective view showing the internal construction of the embodiment; Figure 3(b) is an enlarged sectional view of the latch forming portion and the supporting protrusion; Figure 4(a) and 4(b) illustrate usage of the embodiment; Figure 5(a) is a detailed sectional view of the binoculars; and Figure 5(b) illustrates the operation of the left and right supporting members.

Referring to Figures 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 centre 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 binocular's 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 providing access to an adjusting knob (4). Also, protecting glass (3) is mounted on the front surface of the portion (2).

As 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 reference number (19), as shown in Figure 3. It is to be noted that when binoculars are heavy, they are very inconvenient to use for various purposes.

Figure 5 illustrates the light-weight binoculars.

Left and right objective lens cases (14L, 14R) can be telescopically inserted into left and right eyepiece cases (llL, llR), respectively. The eyepiece and objective cases have an eyepiece (13) and an objective lens (12), respectively, and the cases (llL, llR; 14L, 14R) are made of light-weight materials such as plastics and rubber.

A right front supporting member (15R) and 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 left rear supporting member (18L) which are connected to the eyepiece cases (llR, ilL) respectively, are constructed so that the members (18L, 18R) can be folded towards each other about an inner-threaded cylinder (17) (see Figure 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 (llL, llR).

Therefore, when actuating the adjusting knob (4), the eyepiece and objective lens cases (14L, 14R; llL, llR) can be either withdrawn or extended so as to achieve an optimal focus. In addition, the eyepiece cases (llL, llR) can be folded about the axis of the cylinder (17), the rod (16) and the adjusting knob (4) (see Figure 5(b)). Thus, the distance between the left and right lenses of the binoculars can be adjusted according to the user'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 innerthreaded cylinder (17) is mounted to the binoculars receiving portion (2) by means of holding means (19) as illustrated in Figure 3(a).

Figure 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 Figure 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). Similarly, to return to a cap only, the user simply pushes the visor (5) upward. Then, the latch (2) within the latch receiving groove (10) is caught on the supporting protrusion (21) as illustrated in Figure 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 convenient to use both as a cap and binoculars, but also continuous uses of such binoculars for long hours are possible as well.

Thus at least the preferred embodiment of the invention provides a cap with binoculars which can perform both the functions of a cap and binoculars as well as providing a cap with light-weight binoculars which can be conveniently used and carried for many hours.

It is clearly understood that there are no particular features of the foregoing specification, or of any claims appended hereto, which are at present regarded as being essential to the performance of the present invention, and that any one or more of such features or combinations thereof may therefore be included in, added to, omitted from or deleted from any of such claims if and when amended during the prosecution of this application or in the filing or prosecution of any divisional application based thereon. Furthermore the manner in which any of such featuers of the specification or claims are described or defined may be amended, broadened or otherwise modified in any manner which falls within the knowledge of a person skilled in the relevant art, for example so as to encompass, either implicitly or explicitly, equivalents or generalisations thereof.
