Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to diver's equipment, and more specifically, the invention relates to a rear view mirror which is attachable to most diving masks in production.

2. Background of the Invention

A common problem that divers currently have is the inability to see what is behind them while underwater. First, it is important to know where other divers are located since it is possible to swim away without knowing where the other divers are and the diver may be out of sight of following divers. Second, a diver always has the fear of a shark or other dangerous sea creature coming up from behind in their blind spot.

One prior art device is shown in U.S. Pat. No. 5,216,454 to Berke which discloses a sportsman's face mask for viewing objects in the opposite direction of the normal line of vision. At least one prism, having a pair of complementary faces which are inclined to the and internally reflect rays from objects behind the swimmer into his forward field of vision, is mounted in front of the lens.

U.S. Pat. No. 5,764,334 to Berke discloses a diving mask with supplemental vertical, lateral and posterior fields of vision. A pair of sealed compartments at opposite ends of the diving mask have rotatable mirrorized surfaces which reflect light rays from objects above, below, on the side, and rear of the mask into a diver's view.

U.S. Pat. No. 5,170,190 to Berke discloses a water sportsman's face mask for viewing objects above and below the line of vision. A lens is mounted in front of the frame and a pair of triangular prisms mounted on the lens.

The instant invention is designed to overcome the rear view problems of the prior art with a mask mounted, adjustable rear view mirror.

SUMMARY OF THE INVENTION

The invention consists of a mirror retaining device which is clipped by an attachment means to the top of the mask allowing a convex mirror to be positioned in its operational position within the line of vision of the diver thus facilitating an extension of the diver's view behind, above and to each side as needed. A mirror retaining device provides flexibility of adjustment upwards or downwards. The mirror is slightly convex to prevent direct glare of the sun from being reflected into the eyes of the user and to provide a wider angle of view.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings wherein like numerals designate like and corresponding parts throughout the several views, in FIGS. 1 and 2 a diver's mask is fitted with a mirror retaining device 10 which is clipped by an attachment means to the top of the mask 50 allowing convex mirror 44 to be positioned in its operational position within the line of vision of the diver thus facilitating an extension of the diver's view behind, above and to each side as needed. In FIG. 3, mirror retaining device 10 is shown in an exploded view wherein the relationship between each of its components is shown so that the main body 11 is positioned away from end cap 12 and top locking clip 19 into its pre-assembly position above. Rear locking clip 24 and front locking clip 27 are positioned below main body 11.

Prior to mounting mirror-retaining device 10 to the top of the mask 50, mirror arm 41 is slid through end cap 12 as shown in FIGS. 32-36. Referring now to FIG. 32, end cap 12 is tilted to allow mirror arm 41 (without convex mirror 44 attached) to be passed through. In FIG. 33, end cap 12 is slid toward main body 11 and mirror arm 41 is allowed to pass fully into end cap 12. In FIG. 34, with mirror arm 41 now fully in place in end cap 12, it can be swiveled in the direction of arrow 35 to its operational position. In FIG. 35, end cap 12 is shown clipped onto main body 11 and mirror arm 41 is raised in the direction of arrow 36. FIG. 36 shows mirror 44 in its storage position, arrow 37 shows the direction mirror arm 41 is slid to place it in its storage position inside main body 11.

Referring now to FIG. 37, wherein the assembly/mounting sequence of the various components of the mirror mounting device 10 is commenced. A side elevation of mask 50 is shown partially in section to reveal the relationship between mask skirt 51, mask glass 52, front locking clip 27 and rear locking clip 24. (Optional leveling pin 21 can be used where a swim mask 50 is made without a level shoulder for the mirror mounting device 10 to rest securely thereupon).

FIGS. 30 and 31 show the position of the mounting holes 20 for leveling pins 21 and 21'. Mounting commences with the placement of rear locking clip 24 beneath mask skirt 51. Front locking clip 27 is positioned with its lip firmly against mask glass 52.

FIG. 2 shows the relative positions of main body 11, top locking clip 19, rear locking clip 24, front locking clip 27, and top clip chamber 18. Main body 11 is lowered into position. In FIG. 38, main body 11 has been lowered over the upright faces of rear locking clip 24 and front locking clip 27 so that they are confined within top clip chamber 18. Referring now to FIG. 3, top clip 19 has a locking ridge 23 (shown enlarged in FIGS. 20-21). As front and rear locking clips 24 and 27 respectively are offered up into top clip chamber 18, top locking clip 19 is pushed down into top clip chamber 18 causing locking ridge 23 to engage the serrated face 25 (See FIGS. 11-13 for enlargement of front locking clip 27 and FIGS. 17-19 for enlargement of rear locking clip 24). The simultaneous insertion of locking clips 24 and 27 from the bottom and top locking clip 19 from the top, results in a series of clicks as the serrations 25 on the clip 19 faces and locking ridge 23 on top clip 19 engage. Said engagement is what locks the device firmly in position atop the swim mask 50 as shown in FIG. 39. Mirror arm 41 and convex mirror 44 are omitted from FIGS. 37-39 for clarity. FIGS. 40 and 41 show the final operational installation of the mirror-mounting device 10. FIG. 41 shows the range of movement of the mirror arm assembly. Securing the device 10 through the use of adjustable clips as described herein, facilitates the use of swim masks of different types and specifications.

Referring now to FIGS. 22-29, a rear view of convex mirror 44 is shown in FIG. 22 and FIGS. 23-25 show other views which illustrate the mounting attachment 39. This fitting is used with a mirror arm 41 without a second ball joint whereas in FIGS. 26-29 a ball joint socket 43 is shown as the preferred embodiment. FIGS. 3 and 4 show the differences between the straight mirror arm 41 with one ball-joint end 40 (FIG. 3) and a "U" shaped mirror arm 41 with an additional ball-joint 42 at its furthermost end. FIG. 4 also shows convex mirror 44 in two of the many possible positions to which it can be adjusted using the ball-socket joints 40 at either end of mirror arm 41. The mirror arm 41 can be adjusted at a 20.degree. angle up and down and from 180.degree. to 90.degree., and the mirror 44 can swivel 360.degree..

Referring now to FIGS. 5-8, specifically to the characteristics of front locking clip 26, in the enlargement of front locking clip 26 and its ancillary components, adjustable locking clips 29, locking clip slots 31 are shown in sectional detail to illustrate locking ridge 32 (present on each side of aperture 31). In use, adjustable locking clips 29 are used to facilitate a variable adjustment of the distances between the vertical plane of front locking clip 26 and mask glass 52 (FIGS. 37-39), thus permitting the use of swim masks with differing specifications. The characteristic use of serrated faces and locking ridges throughout the instant device provides a positive method of fixing together the component parts into a compact resilient unit, which is secure enough to remain in position atop a diver's mask while diving, while retaining the ease of disassembly required for routine maintenance cleaning, etc.

Referring now to FIGS. 11-16, these are alternate embodiments of front locking clips. Front clip 27 is used where a particular mask configuration permits its use without need to adjust in relation to the mask glass 52. Similarly, front locking clip 28, through the addition of ridges 34, permits its use on masks where there is no need to adjust it in relation to the mask glass 52. The preferred embodiment is as shown in FIG. 6 with adjustable front clip 26.

The mirror mounting device 10 of the invention may be made from high-quality, ABS plastic and in a variety of colors. Mirror 40 is a marine mirror.

Thus it will be appreciated that the present invention provides a novel diver's rear view mirror which can be mounted on most existing dive masks. It is contemplated that other embodiments and/or modifications may be made in the present invention without departure from inventive concepts manifested by the disclosed embodiments. It is expressly intended, therefore, that the foregoing description is illustrative only of preferred embodiments, not limiting, and that the true spirit and scope of the invention be determined by reference to the appended claims.
