a typical cap or hat of the type with which the invention is utilized is shown in fig1 . the cap 10 includes a headband region 12 from which the crown 14 extends . a visor 16 extends forwardly from the headband and the visor includes an upper surface 18 , an under surface 20 , a front convex peripheral region 22 , and lateral peripheral edges 24 substantially parallel to each other . hats or caps of this type are of the general disclosed configuration , and it will be appreciated that the exact form of the periphery of the visor may slightly differ , i . e . the lateral edges 24 may converge rather than being substantially parallel . the visor protector basic component is the sheet material generally indicated at 26 which is formed of a soil resistant flexible material such as vinyl or other synthetic composition or of a washable fabric which may be readily cleaned which is attractive in appearance and lightweight . it is also to be appreciated that the material 26 may be of a color which matches or contrasts the crown color , and the material 26 may be of leather , plush or other high quality material , and it is to be understood that the particular composition of the material 26 does not form a part of the instant invention . the protective material 26 may be defined by single planer sheet of flexible material , or several pieces sewn together , and the material includes ends 28 and 30 and lateral sides 32 and 34 . preferably , the lateral sides 32 and 34 are of a modified v configuration , as shown in fig3 although the exact configuration of the lateral sides is a matter of choice . the central region 36 of the material may be cut and sewn together in a configuration to conform to the configuration of the cap visor periphery 22 , or if a slightly elastic protective material is used such forming of the central region is not necessary . as shown in fig3 and 4 , in the disclosed embodiment the central region is sewn together at 38 adjacent the lateral edges 32 and 34 to configure the central region for a conforming fit to the visor peripheral portion 22 . the ends 28 and 30 of the material 26 are folded over and hemmed by sewing as at 40 forming loops 42 extending the length of the ends , and as will be appreciated , the loops 42 receive the fastening structure for the visor protector . a flexible cord 44 , is located within each of the loops 42 , and preferably , the cord 44 is in the form of a single continuous loop extending through both of the hem loops 42 and is of such length as to have accessible portions 46 and 47 extending from the ends 28 and 30 , respectively , upon which the fastening clips may be affixed . the clips 48 may be of the frictional u - shaped type , or may include pivotally mounted jaws capable of opening and closing , whereby the clips may be firmly attached to the lateral edges 24 of the visor . in use , the protective material 26 is placed upon the cap visor 16 wherein the material portion 50 overlays the visor upperside 18 , while the material portion 52 is disposed adjacent the visor underside 20 . the central region 36 will be closely engaging and folded over the visor front periphery 22 , fig5 and the cord portions 46 will be disposed adjacent the visor upper surface 18 , while the cord portions 47 will be disposed adjacent the visor under surface 20 as shown in fig1 and 2 , respectively . the clips 48 will be attached to the visor lateral edges 24 adjacent the headband 12 , and the clips will located such that the cord 46 is under slight , but not excessive tension . the tension within the cord 46 will pull the material central region 36 into close configuration with the visor peripheral edge 22 and maintain the material portions 50 and 52 in close relationship to the visor surfaces 18 and 20 , respectively , as apparent from fig5 . as the visor 16 has a slight upward convex configuration the protective material portion 52 will not directly engage the visor underside 20 as apparent in fig5 . as the dimensions of the protective material 26 are such that the portions 50 and 52 cover the majority of the visor surfaces 18 and 20 , and as the material 26 is disposed upon the visor at those locations normally handled by the hat wearer the protective material effectively prevents direct soiling of the visor . upon the material 26 becoming soiled release of the clips 48 permits the material to be readily removed from the hat visor and the material may be cleaned by wiping or washing , and then may be reapplied to the cap visor . it is also appreciated that the material 26 may be of an inexpensive material whereby the entire protector , or just the material 26 may be discarded when soiled . decorations or advertising may be readily applied to the protector material portions 50 or 52 , and by forming the material of attractive colors and unusual texture the protector aesthetically adds to the appearance of the cap in addition to its utilitarian function . it is appreciated that various modifications to the inventive concepts may be apparent to those skilled in the art without departing from the spirit and scope of the invention .
the invention relates to a protector for cap visors consisting of a flexible sheet of soil resistant or washable material having ends and lateral sides which is folded over the visor periphery and the material includes fastening cords attached to clips which are releasably affixed to the edges of the visor adjacent the cap headband . the protective device covers the majority of the visor and by the use of colors , decorations or advertising the protector ascetically adds to the cap appearance .
