United States Patent Of'fice 3,124,379 ANTI-RATTLING HOOK Allen E. Lorch, 5120 Lincoln Ave, Los Angeles, Calif. Filed Oct. 3, 1961, Ser. No. 142,670 1 Claim. (Cl. 292F114) This invention relates to improvements in hooks usable to maintain doors and other closure members in their closed positions and more particularly to a spring loaded hook of an anti-rattling character.

Among the objects of the invention are: to provide a hook that will more safely maintain itself in its operative position, and to provide an improved means to hold in operative position the spring with which the hook is loaded.

The invention includes, as a new article of manufacture, a novel clip applicable to a conventional hook to hold in place on said hook a spring which yieldingly holds the hook in an extended position.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawing, illustrative of a preferred embodiment of the invention,

FIG. 1 is a side elevation of the device, the extended position of the hook proper being indicated by a dotted line.

FIG. 2 is a top plan view of the device.

FIG. 3 is an end elevation looking at the left end of FIG. 1.

FIG. 4 is a vertical section on line 4-4 of FIG. 2, parts being broken off to contract the view.

FIG. 5 is an extended view of the spring holding clip as it appears before the final bending operation.

Referring in detail to the drawing, the hook proper 5 together with its shank 6 and eyeletted portion 7 is formed from a single rod which is circularly bent at one end to provide the eye 8 with which cooperates the eyebolt or screw 9 or other fastener to which the hook is anchored.

A clip formed of a strip of form retaining sheet material, desirably sheet metal, is mounted upon the hook and forms a partial housing for its eyeletted portion 7 and the adjacent portion of the hooks shank. Said strip is right angularly bent toward the same end at two spaced apart lines 15a and 15b in its mid-length portion to provide a cross-wall 16 which has a central aperture 16a (see FIG. 5) through which the hooks shank is slightly slidable.

A compression spring 17 is loosely coiled around the hooks shank with one of its ends abutting said crosswall and its opposite end abutting at least one of the two shoulders 7a and 7b resulting from circularly looping the eyeletted part of the hooks shank. As a result the hook proper is normally retracted by the spring to the full line position of FIG. 1, but it can be extended 3,124,379 Patented Mar. 10, 1964 to the dotted line position of FIG. 1 against the opposition of the spring when necessary.

It is to be observed that the thickness of the eyeletted part 9a of the screw 9, which occupies the eye 8 is considerably less than the diameter of that eye, thus permitting the amount of tolerance or spring opposed play indicated by the double headed arrow 25 in FIG. 4.

Viewing the clip 15 in its extended condition, shown in FIG. 5, each end portion thereof is circularly enlarged as indicated at 29, around each of the apertures 27. The eyeletted part 9a of the screw 9 extends through said apertures 27 when the clip is in its mounted position.

This device not only prevents doors from rattling in the wind, but also facilitates mounting in its operative position the spring loaded hook, for it provides a spring opposed tolerance which takes care of inexactness in positioning the eyeletted screw 9 and the eyeletted screw (not shown) carried by a door or other closure.

In assembling, after the clip has been bent into its final form and the spring 17 has been put into place by threading it over the hook proper, the clip 15 is threaded over the hook proper by means of its aperture 16a, and its cross-wall 16 is abutted against the spring. Then the eyelet portion of the screw 9 is crirnped down from an open condition after having been inserted through the alined eyes 8 and 27.

I am aware that it is not broadly new to provide extensible, spring loaded hooks, but this invention relates to the improvement upon such structures defined by the claim which follows.

I claim:

A device of the kind comprising a hook provided with a shank consisting of a rod circularly looped at one end, thus providing an eye, a clip of form retaining sheet material mounted upon said shank and forming a partial sleeve therearound, said clip having oppositely disposed spaced apart eyeletted portions at one end and having at its opposite end a cross-wall with an opening through it through which the shank of the hook is slidable, a fastening member for the hook having an annular end portion extending through both the eyeletted end portions of said clip and through the eyelet of said rod, and a compression spring loosely coiled around said rod under compression, one end of said spring abutting said cross-wall and the opposite end thereof abutting the eyeletted end portion of said rod, the part of said fastener which passses through the eye of said rod occupying only a part of the diameter of that eye, thus allowing a limited longitudinal movement of said rod in opposition to said spring.
