H. T. BURDICK HOOK FASTENER July 1, 1958 Filed July 17, 1953 Sheets-Sheet 2 noon FASTENER Hugh '1. Burdick, Chicago, 111., assignor to Illinois Tool Works, Chicago, IlL, a corporation of lllinois Application 31113 17, 1953, Serial No. 368,656 Claims. (Cl. 24S-224) The present invention relates to a novel supporting assembly, and more particularly to a novel hook-like assembly adapted to be secured to an apertured panel.

There are many instances when it is desirable to secure article supporting hooks to panels of work benches, lockers, and the like. In many cases, it is difficult to mount such supporting hooks heretofore known, because the hooks require some securing device to be attached thereto from the back side of the panel, and the back side of the panel is often inaccessible. It is, therefore, an object of the present invention to provide a novel hook assembly which may be quickly and easily secured to an apertured panel from the front side of the panel and without any need for auxiliary fastening means, such as nuts, screws, or bolts.

Another object of the present invention is to provide a novel hook assembly of the above described type which is of simple construction and may be readily and economically manufactured 'by standard bending and stamping operations.

Another object of the present invention is to provide a novel hook assembly of the above described general type which includes an elongated hook-like element and a hanger member which may be easily assembled with an apertured panel for supporting the hook-like element.

Still another object of the present invention is to provide a novel hook assembly as described in the preceding paragraph wherein the hook-like element and the hanger member are formed so that a substantial portion of any weight on the elongated hook element is transferred to the panel rather than the hanger member.

A more specific object of the present invention is to provide a novel one piece hanger member for use in a hook assembly of the above described type, which hanger member may be readily manufactured from sheet material.

Still another object of the present invention is to provide a novel hanger member as set forth in the preceding paragraph, which hanger member may be secured to a panel having an elongated aperture in a manner so that the hanger member, and thus the hook assembly, may be adjusted longitudinally of the aperture.

Other objects and advantages of the present invention will become apparent from the following description and the drawings, wherein:

Fig. 11 is a cross sectional view taken along line 11--11 in Fig. 10 and also shows the hook element in place; and

Fig. 12 is a plan view of a blank utilized to manufacture the hanger member shown in Fig. 7.

Referring now more specifically to the drawings, wherein like parts are designated by the same numerals throughout the various figures, a hanger assembly 14 embodying the principles of this invention is shown best in Figs. 1 and 4. The assembly 14 includes a hanger member 16 which is adapted to be secured to a panel 18 having an aperture 20 therein. The assembly 14 also includes a hook element or member 22 which extends through the aperture in the panel and is supported by the hanger member.

The hanger member 16 is preferably made from the sheet material blank shown in Fig. 6 and includes a pair of spaced "walls 24 and 2-6 which merge at their lower ends with angulariy disposed walls 25 and 3%, respectively. Lower edges of the walls 28 and 3b are joined together by a "bottom section 32, as shown best in Figs. 2 and 5. Thus, the wall sections 2428 and 26-36 provide an integral cradle-like structure adapted to receive the hook member 22, as shown best in Fig. 1 and restrain the hook member against pivotal or turning movement in a horizontal plane. The upper ends of the

wall sections

24 and 28 are bevelled, as at 31 and 33, to eliminate the possibility of an article catching as the article is being placed on the hook member.

In order to mount the hanger member 16 on the panel 18 means is provided for clampingly engaging opposite sides of the panel. This means includes a pair of

finger portions

34 and 36 which are adapted to be inserted through the aperture 2% for engagement with the back surface of the panel. These finger portions are respectively integrally connected with the walls 2-4 and 26 by substantially flat laterally extending sections 33 and 43'. As shown best in Figs. 3 and 4, the

finger portions

34 and 36 are bent rearwardly at an angle to the plane of the fiat sections 33 and 49 to provide

abutments

42 and 44 engageable with the lower edge of the panel aperture Each of the fingers then extends forwardly to provide

panel clamping surfaces

46 and 48. Preferably, the free ends of the fingers are disposed to extend rearwardly, thereby providing cam surfaces 50 and 52 for facilitating insertion of the fingers through the aperture. With this structure, the hanger member may be readily assembled with the panel merely by first inserting the cam portions 59 and 52 of the fingers through the aperture and then sliding the hanger downwardly until the

abutment surfaces

42 and 44 engage the lower edge of the aperture. In order to prevent accidental removal of the hanger member from the panel, the fingers are preferably formed so that the panel is resiliently clamped between the fingers and portions of the hanger overlying the front surface of the panel.

In order to provide the forwardly extending

walls

24 and 26 with means for cooperating with the resilient fingers 34 and 35 to grip the panel,

tabs

54 and 56 extend inwardly from the walls 2-4 and 26, respectively, as shown best in Figs. 2 and 5. In addition, stabilizing feet '58 and 60 extend outwardly from the lower ends of the

walls

24 and 26. These stabilizing feet not only help to clamp the hanger to the panel, but also restrain the walls engagement with the panel.

Wall sections 28 and numerals. However, the assembly 7 A substantially 24 and 26 from twisting in the event a load having a horizontally directed component is applied to the hook member 22. The

tabs

54 and 56 also cooperate with the mounted hook member to prevent upward movement of the hanger member and thus hold the resilient fingers in Furthermore, the

tabs

54 and 56 provide a bearing surface for the hook member; thereby preventing injury to the panel surface, especially when the panel surface is painted.

V The hook'rnember 22 include's an article supporting shank 62 which may be made from a metal rod or any other suitable material, such as an extruded or molded plastic rod. Preferably, the outer end of the shank 62 is turned upwardly, as at 64, to prevent articles from slipping off of the shank. As shownbest in Fig. 4, the inner or attachment end of the hook member is provided with a pair'of substantially

parallel portions

66 and 68 which are integrally connected by a transverse portion 70. The

parallel portions

66 and 68 extend at an angle to the shank 62, which angle may be formed in accordance with the angle it is desired to have the shank extend from the panel 18. The book, member 22 may be assembled by first inserting the end portion 66 between the

wall sections

24 and 26 of'the hanger and through the aperture of the panel in the manner shown in dotted lines in Fig. 4. The hook member is then pivoted downwardly t the full line position of Fig. 4 so that the portion 66 abuts the inner surface of the panel, and the parallel portion 68 abuts the

tabs

54 and 56 of the hanger. In this position, it should also be noted that the transverse portion 78 of the hook member engages the top edges of the

hanger tabs

54 and 56 and ,is restrained against outer movement thereby. Preferably, the transverse portion 78 is provided with a flattened area 72 for engagement with the

tabs

54 and 56 so that the hook member when under load tends to pivot about the upper edges of the

tabs

54 and 56 so that a substantial portion of the load is transmitted transversely to the panel by the hook 7

portions

66 and 68.

When the hook member 22 position, a substantial portion closed between the generally L-shaped walls provided by the wall sections 2428 and 2638. The shank is thus securely retained against any swinging or turning movement in a horizontal plane. In order to prevent inadvertent upward movement of the hook member, the 30 are provided with

protuberances

74 and 76 engageable with the'shank 62 in the manner shown best in Fig. 2. The inherent flexibility of the

wall sections

28 and 38 is preferably increased adjacent these protuberances to permit the walls to spring apart as the hook member is being assembled. This may be accomplished by providing the walls 28 and 39 with

apertures

78 and 80 adjacent the protuberances, and, in addiis in its fully assembled tion, if desired, the bottom wall section 32 may be re-' ces'sed, as at 82 (see Figs. 3 and Another hanger assembly 84 embodying the principles of this invention is illustrated in Figs. 7, 8, and 9. In this embodiment, the hook member is identical to the above described hook member22, as indicated by the reference 84 includes a hanger member 86 of modified form.

The hanger member 86 includes a pair of U-shaped

sections

88 and 90 which have

adjacent walls

92 and 94 thereof integrally joined by

wall sections

96, 98, and 100. flat section 102 extends laterally from an outer wall 104 of the U-shapedsection 88, and a similar flat section 106 extends from the wall 108 of the U-shapcd section 90. These'substantially flat sections correspond to the above described

sections

38 and 40 of the hanger member 16, and

resilient finger elements

108 and 110 extend from the

sections

102 and 106 in the same manner as the above described

finger elements

34 and 36 extend from the flatsections.

The hanger member 86 also inof the'shank 62 is encludes

stabilizer feet

112 and 114 which correspond to the above described

stabilizer feet

58 and 60.

As shown in Fig. 7, the on the apertured panel is assembled with the hanger member 86 by inserting the end portion 66 through the aperture defined by the wall sections 96 and 98.- The hook member is then pivoted downwardly until the shank portion 68 is disposed be: tween the 'walls' 92 and 94 of the U-shaped portions.

It is believed to be clear that the walls 92"and 94 will function to prevent horizontal swinging movement of the hook member in substantially the same manner as V the above described

wall sections

24 and 26. Asshown in Fig. 9, the hook member 22 pivots about and presses against the wall section 98 so that this wall section performs essentially the same functions as the above de- Fig. 12 illustrates a simple tlat blank fromwhich the.

hanger member 86 may be formed. It will be obvious when comparing the blanks of Figs. 6 and 12 that the hanger member 86 requires considerably more sheet material stock than the hanger 16, and while this has some disadvantage from an economy standpoint, the looped or U-shaped sections of thehanger 86 provide substantially increased strength and rigidity for use when'hcavy loads are to be supported.

'Figs. 10 and 11 illustrate another slightly modified form V V of the present invention which includes a hanger member 120 which is substantially identical to the above described as indicated by the application of hanger member 86 identical reference numerals to identical parts. The hanger 120 differs, from the hanger 86, only in that a pair of armsj122and 124 are struck from the. U-shaped sections 88 and so as to project along opposite sides of the hook member Fig. 11. These arms perform the samefunction asthe

wall sections

28 and 30 in the above described hanger 16.; Thus, the

arms

122 and 124,.which normally converge slightly toward each other as indicated in dotted lines in Fig. 11, resiliently grasp, opposite sides of thehook member to eliminate any possible lateral play. It is seen,

therefore, that the hanger member incorporates some 7 of the advantages of both of the above described

hanger members

16 and 86. From the above description,

has provided a device of simple and economic 'construcrelatively lightweight material While the preferred embodiments of the present in anddescribed herein, it is vention have been shown" obvious that many structural details may be changed without departing from the spirit and scope of the appended claims.
