HINGE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates generally to a hinge, and particularly to a hinge permitting easy separation of hinged elements.

2. Description of the Prior Art The very sensitive and extremely delicate modern mechanical sound reproducing equipment generally uses a dust cover to protect the turntable, tone arm, and other elements projecting from a housing of the equipment. These dust covers are usually a transparent member provided with a cavity arranged for fitting over the projecting elements on the associated equipment, and are either separate from and merely rest on the equipment housing, or are hinged to the equipment housing by a conventional hinge. It is desirable, however, to have the dust cover arranged on the equipment housing so as to be either removable therefrom or pivotal with respect thereto, as one prefers.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved hinge of simple yet rugged construction.

It is another object of the present invention to provide a hinge which permits easy separation of hinged elements.

It is yet another object of the present invention to provide a hinge especially suited for mounting a dust cover on an equipment housing.

These and other objects are achieved according to the present invention by providing a hinge having: a first member, and a second member provided with a holder for receiving the first member and permitting same to pivot with respect to the second member. Advantageously, the first member is a planar portion of a dust cover.

The second member includes a substantially planar base, while the holder preferably is formed by first and second spaced, parallel planar projections extending perpendicularly and codirectionally from the member base. First and second flanges extend in parallel, codirectional relationship obliquely from the free ends of the first and second projections, respectively. The first flange is advantageously arranged extending toward, or in the general direction of, the second projection. In this manner, the first member, which is preferably a substantially planar portion of a dust cover, and the like, is arranged between the projections, and is selectively and sequentially arrangeable in a position parallel to the projections and in a position parallel to and abutting the flanges.

A, for example, wedge-shaped tab is advantageously provided on the first projection so as to extend toward the second projection for selectively cooperating with the first flange and locking the first member between the first flange and the tab.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now more particularly to FIGS. 1 through 3 of the drawings, the reference numeral 10 designates a hinge according to the present invention which is illustrated as tying a conventional dust cover 12 to a conventional equipment housing 14 with which cover 12 is associated. Hinge 10 is formed by a first member 16 in the form of a planar portion of dust cover 12, and a second member 18 provided with a holder 19 arranged for receiving member 16 and permitting same to pivot with respect to member 18. As can best be seen from FIG. 2 of the drawings, member 16 may be easily withdrawn from holder 19 for separating cover 12 from housing 14.

Referring now to FIGS. 4 through 6 of the drawings, member 18 includes a base 20 mountable on housing 14 in a conventional manner as by

screws

22 and 24 received in suitable slots provided in longitudinal end portions of the generally diamond-shaped base 20. Holder 19 is mounted on base 20, and includes first and second spaced, parallel,

planar projections

26 and 28 extending perpendicularly and codirectionally from base 20. First and

second flanges

30 and 32 are arranged extending in parallel, codirectional relationship obliquely from the free ends of

projections

26 and 28, respectively, with the first flange 30 arranged extending toward the second flange 32.

Webs

34 and 36 are advantageously provided for rigidifying the connections between the base, projections, and flanges.

As mentioned above, member 16 is substantially planar and is arranged between

projections

26 and 28. Specifically, member 16 is selectively and sequentially arrangeable in a position such as shown in FIG. 2 of the drawings wherein member 16 is parallel to

projections

26 and 28, and in a position as shown in FIG. 3 of the drawings wherein member 16 is parallel to and abuts

flanges

30 and 32. That is, portion 16 rests on top of flange 32 and is engaged beneath flange 30 so as to be retained in a eever=epen position as shown in FIG. 3.

By proper design, cover 12 will be stable in the FIG. 3 position.

FIG. 7 of the drawings shows how member 16 is preferably modified with a suitable cut-out 38 arranged forfitting over base 20 of member 18. In this manner,

'the lower edge of member 16 will be flush with housing 14 when cover 12 is in its closed or FIG. 2 position. The tongue portion of cut-out 38 permits member 16 to extend to the upper surface of base 20 when member 16 is arranged in holder 19 of member 18.

It is desirable to modify a hinge according to the present invention in the manner shown in FIGS. 8 and 9 of the drawings so as to effectively lock cover 12 in its open, or FIG. 3, position. Accordingly, FIG. 8 shows a view similar to FIG. 3, but with a substantially wedgeshaped tab 40 provided on projection 26 and arranged extending toward projection 28 for selectively locking member 16 between flange 30 and tab 40. This locked position is the position shown in FIG. 8 of the drawings. When a tab 40 is so provided, the tongue portion of cut-out 38 will be effectively wedged between tab 40 and flange 30 so as to prevent cover 12 from falling to its closed, or FIG. 2, position, or from being accidentally jarred loose from its seat between

flanges

30 and 32.

As can be readily appreciated from the above description and from the drawings, a hinge according to the present invention provides a multi-purpose device which retains acover 12 on an associated equipment housing 14 when the cover is in its closed position, and holds the cover 12 in a. desired open position. Further, cover 12 can be removed from housing 14 as desired by withdrawing member 16 from holder 19.

t The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
