Best Mode for Carrying Out the Invention The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

As shown in Fig. 1 to Fig. 23, a multi-functional cap according to the present invention includes a crown portion formed to cover the head, a visor 20 extended from a crown portion, and an assistant visor that is detachably coupled to the edge of the crown portion and the edge of the visor 20. In the above, the assistant visor comprises foldable visor units, and fixed units for fixing the assistant visor to the crown portion and the visor 20.

That is, in the present invention, the visor is added to the cap having the same or similar construction as an existing cap, so that an assistant visor can be detachably to the cap. It is thus possible to shield portions that are not shielded by the visor of the cap itself from sunlight.

In the above, the assistant visor includes a visor unit that can be folded itself and a fixed unit for fixing the visor unit to the cap.

The assistant visor can be constructed in various shapes in the construction of the visor unit and the fixed unit.

In constructing a visor unit of the assistant visor, for example, as shown in Fig. 3 to Fig. 5, a plurality of narrow hardened plastic plates are overlapped so that. they can be extended. At this time, a first support plate and a second support plate are placed at the outmost of the plastic plates. Two or more visor plates are foldab. ly fixed between the first support plate and the second support plate around a shaft, thus forming the visor unit. It is possible to construct an assistant visor having the visor unit. Fixing projections are formed at the lateral end of the visor plates. If the assistant visor is extended, it can be extended by the fixing projections until it is not extended. Thus one wide visor unit can be formed.

Moreover, the assistant visor is overlapped so that hardened paper plates can be extended, thus forming the assistant visor having one wide visor unit. At this time, it may be difficult to form the fixing projections in the paper plates. Therefore, the hardened paper plates

are fixed together by binding means such as a Velcro paper using binding means, thus forming one wide visor unit.

The visor unit of the assistant visor can be formed by foldably overlapping plate-like body such as textile or paper as shown in Fig. 7.

In this case, the textile or paper is poor in mechanical properties. Thus, there will be a problem that the textile or paper goes down. In order to form one wide visor unit, the first support and the second support are integrally fixed at both sides of the visor plate. The first support and the second support can be connected by a resilient band. Even in a state where the visor plate is extended by the resilient band, the visor unit will not go down. The resilient band is resilient. If the assistant visor is bent, it contracts. If the assistant visor is extended widely, it is extended and folded.

As shown in Fig. 8, the visor unit of the assistant visor can have a plane state so that the plate-like body such as textile or paper can be folded. One end of the visor unit is converged to one point to form the overlapping element lie a fan. In this case, In this case, the textile or paper is poor in mechanical properties. Thus, there will be a problem that the textile or paper goes down. In order to form one wide visor unit, the first support and the second support are integrally fixed at both sides of the visor plate. The first support and the second support can be connected by a resilient band. Even in a state where the visor plate is extended by the resilient band, the visor unit will not go down. The

resilient band is resilient. If the assistant visor is bent, it contracts. If the assistant visor is extended widely, it is extended and folded.

As shown in Fig. 19, the visor unit of the assistant visor may include an assistant visor having a shaft center. In the above, an insertion pin integrally formed with the shaft center is inserted into the insertion groove formed in the crown portion. The plurality of the support shafts are hinged to the shaft center. Thus, these support shafts foldably support the'visor membrane. Furthermore, in Fig. 20, a shaft fixed plate is formed instead of the shaft center. The support shafts are fixed to the shaft fixed plate. The shaft fixed plate is detachably fixed to the edge of the crown portion of the cap by means of Velcro paper, etc.

As shown in Fig. 21, the visor unit of the assistant visor includes a plate-like body and supports for supporting the plate-like body. One lateral end of the support is variably fixed to the rail unit that is detachably fixed to the end of the crown portion. The rail unit has a groove that is extended in the length direction so that the supports can be varied. The supports are folded along the groove. Accordingly, as the plate-like body attached to the supports is extended, one wide visor unit is formed. The plate-like body may be textile, paper, plastic film, etc.

As shown in Fig. 22, the visor unit of the assistant visor includes a plate-like body and supports for supporting the plate-like body. One

lateral end of the support is variably fixed to the rail unit that is detachably fixed to the end of the crown portion. In the rail unit, a ring formed at the end of the support penetrates the rail. Thus, the supports are folded while being varied along the rail. Accordingly, as the plate- like body attached to the supports is extended, one wide visor unit is formed. The plate-like body may be textile, paper, plastic film. etc.

As shown in Figs. 1 to 8, the visor unit of the assistant visor includes a visor pinchcock unit into which the edge of the visor can be inserted, and a crown pinchcock unit into which the edge of the crown portion can be inserted. The visor pinchcock unit of the fixed unit is fixed to the edge of the visor and serves to fix the assistant visor to the cap. Furthermore, the crown pinchcock unit is fixed to the edge of the crown portion and serves to fix the assistant visor to the cap. As shown in Fig. 3, the visor pinchcock unit is integrally fixed to the first support plate of the assistant visor and includes a coupling piece, a coupling groove and a guide slope face.

Therefore, the edge of the visor inserted into the visor pinchcock unit is inserted into the coupling groove along'the guide slope face and contacts the coupling piece so that it is prevented from deviating.

Therefore, it is possible to fix one side of the assistant visor to the edge of the visor. The crown pinchcock unit also has a shape similar to the visor pinchcock unit and serves the same function as the visor pinchcock unit. That is, the crown pinchcock unit is integrally fixed to the second

support plate of the assistant visor, as shown in Fig. 3, and includes a coupling piece, a coupling groove and a slope guide face. Therefore, the edge of the crown portion inserted into the crown pinchcock unit is inserted into the coupling groove along the slope guide face and contacts the coupling piece, so that the crown portion is prevented from deviating.

Therefore, the other side of the assistant visor can be fixed to the edge of the crown portion. Accordingly, the assistant visor has one end fixed by the visor pinchcock unit and other side fixed by the crown pinchcock unit. Therefore, the whole assistant visor is detachably fixed to the cap.

The state fixed thus is shown in Fig. 1 and Fig. 2. Fig. 1 shows a state where the assistant visor is unfolded and Fig. 2 shows a state where the assistant visor is folded.

As shown in Fig. 9 to Fig. 12, the fixed unit of the assistant visor includes an insertion groove into which an insertion pin integrally formed with an assistant visor is inserted, two or more clips fixed to one side of the assistant visor, and a pair of zippers each having one side fixed to the surface of the crown portion and other side fixed to the assistant visor so that the zippers can be coupled each other. Therefore, as shown in Fig. 11, the insertion pin integrally formed with the overlapping element of the assistant visor is inserted into the insertion groove formed in the crown portion. The clips fixed to one side of the assistant visor is fixed to the edge of the visor 20 of the cap. Also, the zippers are coupled each other. Thus, the cap and the assistant visors can be

detachably fixed each other at three or more places.

As shown in Fig. 13 and Fig. 14, the visor unit of the assistant visor further includes a pair of Velcro papers whose edges are coupled.

Therefore, as shown in Fig. 14, after the insertion pin is first inserted into the insertion groove, the zippers are coupled. The first Velcro paper that is fixed to an assistant visor at one side of the assistant visors attached in pair around the cap, and the second Velcro paper fixed to the assistant visor at the other side are coupled. Thus, the assistant visor can be closely fixed to the cap around the cap.

As shown in Fig. 16, the fixed unit of the assistant visor includes an insertion groove into which an insertion pin integrally formed with the assistant visor is inserted, and a pair of Velcro papers each having one side fixed to the surface of the crown portion and other side fixed to the assistant visor so that the pair of the Velcro papers can be coupled each other. As shown in Fig. 17, the insertion pin fixed to the overlapping element of the assistant visor is inserted into the insertion groove formed in the crown portion. The Velcro paper at one side of the assistant visor is coupled to the Velcro paper of the visor of the cap. At the same time, the Velcro paper at the other side of the assistant visor is coupled to the Velcro paper fixed to the crown portion of the cap. Thus, as shown in Fig. 18, the assistant visor can be detachably fixed each other at three or more places against the cap.

As shown in Fig. 19 to Fig. 23, assistant visors according to

another embodiment of the present invention can be provided.

In Fig. 19, two or more pinchcocks are formed so that the visor unit can be formed more widely. In the above, there are formed two or more pinchcocks at which the visor unit that is folded is converged.

Thus, a more wide visor unit can be formed. An insertion pin inserted into the insertion groove of the crown portion is formed at one side of the fixed unit. The second zipper is attached to one edge of the visor unit fixed to the fixed unit. The second zipper is coupled to the first zipper and the zipper fixed to the edge of the crown portion. As a result, an assistant cap window can be detachably coupled to the cap.

Furthermore, a Velcro paper is attached to the edge of the visor unit that corresponds to the edge to which the second zipper is fixed. The Velcro paper is coupled to the Velcro paper of the visor unit of the assistant cap window having the same construction that is detachably in the direction opposite to the cap. As shown in Fig. 20, when the cap is attached, edges of the visor unit are fixed one another. Resultantly, the visor unit can be firmly fixed to the cap.

According to another embodiment of the present invention, there is provided an assistant visor as shown in Fig. 21 and Fig. 22. The assistant visor is means for foldably fixing the visor unit within the rail groove formed in the rail plate. The variable holder is inserted into the assistant visor and the assistant visor is variably fixed within the rail groove. The visor unit is fixed to the variable holder. Thereby, the

visor unit can be foldably constructed. At this time, the visor unit can be made using all kinds of plate-like body such as plastic film, paper and textile. A third zipper is integrally fixed to both end edges of the visor unit. As shown in Fig. 22, by coupling the third zippers, the assistant visor is completely surrounded by around the crown portion, thus forming one wide visor unit. Furthermore, the visor unit is foldable.

The rail plate in which the visor unit is formed is detachably attached to the crown portion, so that the whole visor unit can be detachably constructed to the cap. By adding the assistant visor if needed, the visor can be separated from the cap.

Moreover, instead of the rail plate and the variable holder, the visor may include a rail plate and a rail hanger ring that is variably fixed along the rail formed in the rail plate as shown in Fig. 23. In the same manner as the variable holder in the rail plate, the visor unit is fixed to the rail hanger ring. Thereby, the visor unit can be foldably constructed.

At this time, the visor unit can be made using all kinds of plate-like body such as plastic film, paper and textile. A third zipper can be integrally fixed to both end edges of the visor unit.

The rail unit or rail unit of the assistant visor can be detachably attached to the edge of the crown portion by means of the pair of the Velcro paper that can be coupled.

Fig. 1 shows a state where an assistant visor 11 is inserted into the right and left of a visor 20 of a cap and a visor plate 14 is then

extended according to an embodiment of the present invention. Fig. 2 shows a state where the assistant visor 11 inserted into the right and left of the visor 20 is folded and laid on the visor 20 according to an embodiment of the present invention. Fig. 3 is a perspective view illustrating the assistant visor 11 shown in Fig. 1 and Fig. 2 according to 't an embodiment of the present invention.

Referring to Figs. 1 to 3, if a cap having the visor 20 that is extended toward the front of the forehead is used, an assistant visor 11 is sued in order to protect the sides of the face from sunlight. A user who wears the cap inserts the assistant visor 11 into edges of the left and/or right side of the visor 20. For this, a visor pinchcock unit 16 that can be inserted into the left and/or right edge of the visor 20 is formed in a first support plate 12 of the assistant visor 11. The visor pinchcock unit 16 includes a coupling piece 161 having a guide slope face 163.

The left and/or right edges of the visor 20 are easily introduced by the guide slope face 163, inserted into the coupling piece 161 and fixed to a coupling groove 162. The coupling piece 161 is formed deeper than an example shown in Figs. 1 to 3.

After the assistant visor 11 is fixed to the edge of the visor 20, a visor plate 14 of a fan shape extended from the first support plate 12 is extended up to the lateral rear side of a crown portion 10 in a fan shape around a shaft 15. Thereafter, a crown pinchcock unit 17 is inserted into a corresponding cap brim location of the crown portion 10 using the

crown pinchcock unit 17 formed in a second support plate 13. Thus the assistant visor 11 is fixed to the cap firmly. Like the visor pinchcock unit 16, the crown pinchcock unit 17 includes a coupling piece 171 having a slope guide face 173. Accordingly, a coupling groove 172 is formed within the crown pinchcock unit 17. The crown pinchcock unit 17 shown in Figs. 1 to 3 can be implemented fixedly in one direction, but can be implemented so that it can be folded up and down. Thus, even if one of the assistant visors 11 is used, the crown pinchcock unit 17 can be inserted in any direction. As another embodiment, the crown pinchcock unit 17 cannot be formed in manufacturing. Even in this case, the assistant visor 11 can be used without right and left side.

In an embodiment shown in Fig. 3, the visor plate 14 consists of a plurality of hardened plastic visor plates 14. A fixing projection 141 of a structure in which the visor plates 14 can be latched one another is formed at the top and bottom between the continuous visor plates 14.

Therefore, if a user extends the assistant visor 11 with it inserted into the visor 20 in a state where the user holds the support piece 20, the assistant visor 11 is gradually extended from the visor plate 14 located at the bottom by means of the fixing projection 141 of the visor plate 14 and is thus extended up to the visor plate 14 located at the bottom. The length of the visor plates 14 can be the same, but may be different. if needed. For example, it would be preferred that the length of the visor plate 14 that is located around the visor 20 is relatively longer than other

visor plates 14. It is also preferable that the visor plate 14 is thicker as it is close to the shaft 15.

As another embodiment, the visor plate 14 can be made of a plurality of stiff paper materials, as shown in Fig. 6. A Velcro paper 143 that is commercially provided as Scotch tape is adhered so that the visor plates 14 can be attached at the bottom between the continuous visor plates 14.

It is to be understood that the material of the visor plates 14 shown in Fig. 6 may be plastic or stiff fiber. Furthermore, the first support plate 10 and the second support plate 13 of the assistant visor 11 shown in Fig. 1 to Fig. 6 can be implemented using a plastic material in the same manner as the visor plate 14. In this case, it is preferred that a thickness of the first support plate 10 and the second support plate 13 is thicker than that of the visor plate 14. Also, the material of the first support plate 10 and the second support plate 13 may be a metal or nonferrous metals. In this case, a thickness of the first support plate 10 and the second support plate 13 may be similar to that of the visor plate 14.

The axis of the assistant visor 11 shown in Figs. 1 to 3 and Fig. 6 can be fixed by a hanging structure having handing protrusions 153 and handing grooves 123 as shown in Fig. 4 and Fig. 5 even in a state where the visor plate 14 of the assistant visor 11 is arbitrarily extended or folded and is laid on the visor 20.
