DESCRIPTION OF THE INVENTION

(12) The present invention has utility as a removable optical device such as an optical loupe that is mountable to headwear. The inventive loupe is configured to clip on to the brim of a hat, or the bill of a cap or visor, and finds particular utility as an accessory in golf and target sports. Embodiments of the inventive loupe have a pivoting joint for positioning the lens of optical loupe into and out of the line of sight when not in use. The lens of the inventive optical loupe is used for magnifying objects for inspection.

(13) Referring now to the figures, FIG. 1 is a side perspective view of the inventive clip on optical loupe 10 removeably attached to the bill 14 of a cap 16 according to an embodiment of the invention. It is noted that the inventive clip 18 on optical loupe 10 is operative with other forms of headwear as well. A clip 18 attaches to the edge 12 of the bill 14 so as to position the optical loupe 10 in the line of sight of a user. The clip 18 is moveably attached to a lens holder 20 via a socket like connection to be described further in FIGS. 3-5. Arrow 24 is used to indicate the full range of motion of the lens 22. When the lens 22 is positioned in the up position, the lens 22 is parallel to the bill 14, and is out of the user's vision field. Conversely, when the lens 22 is positioned in the down position, the lens 22 is perpendicular to the bill 14, and is in the user's vision field. FIG. 2 is a close up view of FIG. 1 that illustrates the pivoting motion of the lens 22.

(14) FIG. 3 is a front perspective view of the inventive clip on optical loupe 10 deployed in the downward position in the user's field of vision. Fasteners 26, such as pins or screws attach and retain the lens 22 to lens holder 20 that engages into ball socket/slot 28 of clip 18.

(15) FIGS. 4A-4D are a series of perspective views of the clip 18 showing the front, front side, back side, and back of the clip, respectively. Elongated slot 30 engages a hat brim or cap bill. FIGS. 5A-5C are a series of perspective views of lens holder 20 showing the bottom side, back side, and side view of the lens holder 20, respectively. Ball joint 34 extending from arm 32 mounts into slot 28 of clip 18, and allows for up and down positioning of the lens 22, as well as to swivel or rotate the lens 22 sideways. The clip 18 and lens holder 20 may be made of plastic, composites, wood, metals, or combinations thereof.

(16) FIGS. 6A-6C are a series of perspective views of an optical loupe 40 with a ball joint clip 44 for moveable attachment to headwear, such as the bill of a cap according to an embodiment of the invention. The clip 44 has elongated slot 46 that engages a hat brim or cap bill, as well as an arm portion 48 that terminates in a ball joint 50. As best shown in FIG. 6B, FIG. 7, and FIG. 8, ball joint 50 mounts into slot 54 of lens holder 42, and allows for up and down positioning of the lens 22, as well as to swivel or rotate the lens 22 sideways. Fasteners 26, such as pins or screws attach and retain the lens 22 to lens holder 42. The ball joint clip 44 and lens holder 42 may be made of plastic, composites, wood, metals, or combinations thereof.

(17) As best shown in FIG. 6C, FIG. 8, and FIG. 9, a set screw 52 may be used to adjust the tension applied to the ball joint 50 mounted in the slot 54 to control the ease of movement or locking the position of the lens 22 relative to the clip 44. The set screw 52 mounts in threaded hole 56. The set screw 52 may be adjusted with key 58 fitted with a bit 60 that engages the set screw 52. The bit 60 may be a hex, star, torque, Philips, or straight edge depending on the type of set screw 52.

(18) In a specific embodiment the clip 42 may have magnetic properties for attachment to metal surfaces.

(19) The foregoing description is illustrative of particular embodiments of the invention, but is not meant to be a limitation upon the practice thereof. The following claims, including all equivalents thereof, are intended to define the scope of the invention.
