Patented Mar. 2, 1943 UNETED STATES OFFICE HOOK James E. Bales, Aurora, 111., assignor to Lyon Metal Products, Incorporated, Aurora, 111., a corporation of Illinois 6 Claims.

This invention relates to adjustable supporting devices. More particularly, it relates to an adjustable or shiftable hook or peg.

In th case of open panels or cabinet structures having hooks or pegs for supporting materials in an orderly fashion out of the way, it is ordinarily desirable to secure the hooks or pegs in such a way as to provide a maximum of different positions in which the hook or peg may be located. Where the hooks or pegs may be readily 1ocated in a variety of positions a given structure obviously has a much wider field of use. This is important not only to the user, in permitting him to vary his storage arrangements at will, but also to the manufacturer of the equipment since it permits him to standardize the structure and ofier it for sale for the storage of any of a wide variety of articles.

In the adjustable structures of this type heretofore known a very serious defect has, however, existed. In order that they might be readily removed, the hooks or pegs have been loosely supported in place so that they are very easily dislodged, not only when it is desired to relocate them but at other times as well. Thus, in the course of removing materials supported on the hooks or pegs they are frequently dislocated, necessitating their replacement in position before they can be used again. In many cases they may be displaced not only in removing materials but also in placing materials upon them or upon adjacent hooks or pegs.

It is, therefore, an object of this invention to provide a supporting structure, including hooks or pegs, for storing materials, which hooks or pegs are readily adjustable or shiftable to various positions on the support but which are not susceptible to being dislodged during ordinary usage, including placing or removing materials supported on such hooks or pegs.

Another object is to provide a hook to be used in connection with a perforated support, which hook may be readily shifted to any of a plurality of positions on said support and which may be removably secured in any of said positions in such a way that it cannot be dislodged in the normal usage of placing articles upon it or removing them.

A further object is to provide amaterial supporting structure including a panel comprising a plurality of spaced perforations and a hook or peg removably supportable in said perforations, in which structure the hook or peg cannot be dislodged accidentally in normal usage.

A more general object is to provide a supporting structure comprising hooks or pegs which are readily shiftable to a plurality of positions but cannot be accidentally dislodged in normal usage.

Another more general object is to provide a structure including members secured together by means of an opening in one, a lug in another and a threaded member associated therewith.

Other objects will appear hereinafter.

It has now been found that these objects may be accomplished by the structure illustrated in the accompanying drawing which forms a part of this specification and in which Figure 1 isa view in perspective of a hook and a section of panel made in accordance with the present invention;

Figure 2 is a section on the line 22 in Figure 1;

Figure 3 is an enlarged rear elevation of the hook and the section of panel immediately surrounding'it, in Figure 1; p v

Figure 4 is a vertical section on the line 5-4 in Figure 1;

Figure 5 is a view similar to Figure 4, showing the hook partially inserted in position on the panel;

Figure 6 is an exploded view of the hook and attaching screw; and

Figure '7 is a horizontal section on the line 1-! in Figure 1.

Referring now particularly to Figure 1, a section of panel 50 is shown provided with aligned perforations l2 uniformly spaced both vertically and horizontally. Supported on this panel is hook l4. Hook 14 comprises a generally triangular shaped base member [6 adapted to rest against the surface of panel IE]. Centrally, both on a horizontal plane, as at l8, and on a vertical plane, as at 20, this member is bowed out away from the panel [0, with the result that the corner portions of the triangle extend more closely against the panel 10 than do the remaining parts.

Extending perpendicularly outwardly from the top central portion of base It is rod 22 upon tends from the front face of base It to the under side of rod 22 to strengthen and support the'rod. Extending perpendicularly from the rear face of base I6 is a portion 28 which is substantially Portion 28 is bent up-.

an extension of rod 22. wardly to provide an upward extension 30. In

the angle 82 formed by the horizontal portion 28 and upward extension 38, both the horizontal and vertical surfaces are cut away to provide flat faces 34 and 36.

Centrally located near the lower point of the triangular base I6 and extending perpendicularly from its rear face is a rod-like projection 38 generally circular in vertical cross section. On the under side of projection 38, spaced outwardly a short distance from the base, is a semicircular slot 48 wide enough to comfortably receive an edge of plate I8. Immediately above the projection 38 is a threaded opening 42 in base I6. This opening is threaded to receive a self-tapping screw 44.

As will be apparent, the hook I4 and panel I8 cooperate to make the hook shiftable to a variety of positions. For this purpose adjacent holes in a vertical direction are spaced so that the distance from the upper edge of the upper hole to the lower edge of the lower hole in a pair is just a little bit greater than the distance from face 34 to the lowermost point of projection 38, as can be seen in Figure 5, for example, or, conversely, the projection 38 is so spaced from the upper face 34 of portion 28 that the distance between the lowermost part of projection 38 and the face 34 is just slightly less than the distance between the upper edge of the upper one of a pair of vertically adjacent holes and the lower edge of the other. Also, the holes I2 are made slightly larger than the diameter of the projection 38' or, conversely, the diameter of the projection 38 is made slightly less than the diameter of the holes I2, as is also clearly shown in the figures.

To insert the hook into place on the panel, it

is revolved to the position shown by the dotted line in Figure 2, in which position the upturned portion 38 may be readily passed through a hole I2. After the portion 38 has been inserted through the hole I2, the hook is then turned back to the position shown by the solid line in Figure 2, during which revolution the lower projection 38 passes through the hole I2 immediately below that through which the upwardly extending portion 38 has been passed. At this point the hook and panel are in the position shown in Figure 5. In order to secure the hook in place it is thereupon shifted vertically downwardly to the position shown in Figure 4 and the screw 44 is threaded into opening 42 and turned until the head 46 rests against the front face of base I6. As can be seen, during this operation the screw 44 passes through the opening I2 in which projection 38 extends and, since it is sufficiently large, it cuts a thread in the inner edge of the hole I2 through which it extends, thereby firmly securing the hook I4 in position on the panel I8.

It can clearly be seen that no jar encountered in ordinary usage will be suflicient to disengage the hook I4 from the position in which it is fixed, as described. On the other hand, when it is desired to shift the hook to a new position, it is only necessary to unscrew the screw 44 and reverse the operation just described, that is, raise the hook I4 from the position shown in Figure 4 to that shown in Figure 5 and then revolve it from the position shown in the solid lines in Figure 2 to that shown by the dotted lines, whereupon the upward extending portion 38 may be withdrawn from the hole I2 in which it is placed and the hook may be shifted to another pair of adjacent holes in the panel.

Although, as shown in the drawing, the panel is provided with holes over its entire face which are equally spaced both vertically and horizontally, this is by no means essential to the invention. It is, on the contrary, within the scope of the present invention to provide holes spaced in any desired manner over a panel, which may or may not form a part of an enclosure, provided only that each hole be vertically spaced from another hole a uniform distance which, as described above, should be such that from the upper edge of the upper hole to the lower edge of the lower hole is a distance slightly greater than the distance between the face 34 of the hook to be used with the panel and the lower edge of the projection 38. Thus, it will be apparent that, while the horizontal spacing of the holes is generally immaterial, it is ordinarily desirable that the rows of holes be uniformly spaced vertically since with such a construction all but the upper and lower rows of holes can then be used to receive either the upwardly extending portion 38 or the projection 38.

The bowing of the rear face of base I6 is likewise not essential to the invention although it has the advantage that any slight unevenness on the rear face of base I6 does not then interferewith the positioning of the hook on the panel. For like purpose the slot 48 is spaced outwardly from the rear face of base I6 although it is within the scope of the invention to position it immediately adjacent the rear face. Also, the base [6 need not be triangular, with one of the points occupying the lowermost position. It may assume any other desired shape, it being only necessary to make it thick enough and large enough to provide the proper support for the rod 22. -It could, for example, be made square or rectangular or' could be made triangular with a point of the triangle uppermost rather than lowermost.

It will be apparent that where the rod 22 extends from the upper edge of the base I6 adjacent the point where the portion 38 is formed a minimum of shearing strain is put on the portion -38 by objects supported on the rod 22. It is not, however, essential to the invention that the rod 22 be located in this position, and having in mind the articles to be supported on the rod 22, if portion 38 is given sufficient strength, the rod 22 may be located lower down upon the base I6. Ordinarily, nothing is gained by positioning the rod 22 otherwise than as shown in the drawing, and accordingly this positioning of the rod is preferred.

Bridging portion 26 is preferred to add strength but the rod 22 may be of any desired formand construction. It need not necessarily be a rod and it is not essential that it extend perpendicularly from the base I6 nor is it essential that a turned up portion 24 be provided on the end. It is within the scope of the invention to provide any sort of extension from the for.- ward face of base I6 which is adapted to support articles thereupon. Some form of gradual upward curve or bend is ordinarily desirable near the outer end of the supporting means such as rod 22 but it is recognized that for certain purposes such an upward extension may not be desirable and it can therefore be' dispensed with.

The purpose of the screw 44 is to retain the portions 28 and 38 in the position shown in Figure 4 with respect to the adjacent pair of holes I2 in which they extend. It can be seen therefore that screws of types other than screw 44 shown in the drawing will be suitable for this purpose, They should have a slight taper to facilitate their insertion through the hole 42 and preferably the screw will be large" enough and the hole 42 will be so placed that a portion of the threads will come into contact with an edge of the hole l2. When so constructed the hook is more firmly secured in place and the contact between the threads of the screw and the panel serves to prevent the screw from loosening and dropping out.

It is within the scope of the invention, however, to provide a screw and to so position the opening 42 that a tight fit is not obtained, provided the construction is such that when the screw is in position the hook cannot be shifted upwardly sufiiciently to assume the position shown in Figure 5. Thus a very satisfactoryconstruction may be obtained without havingthe screw contact the plate It) at all if the screw is arranged so that the head portion'can be turned up tightly against the forward face of base l6 so that it does not readily loosen.

More generally, any desired means may be employed to secure the hook against vertical shifting although preferably the means will be such that it can be readily inserted in and removed from the opening and has suificient size so that when inserted in the lower opening l2 with projection 38 in its lowermost position it will prevent the projection 33 from moving upwardly to a position where it may be withdrawn from opening l2. It will be apparent that other meansthan a member threaded into the hook structure will be suitable for this purpose. The latter is preferred, however, because it is readily adjusted and can be made to position the structure firmly.

By reason of the cooperative relation between the pair of projections they are adapted to support the hook structure relatively firmly in the pair of spaced openings even without a member, such as screw 64, projecting into the lower opening. Accordingly, where maneuverability is more important than firm positioning a member, such as screw 44, may be omitted from the hook structure and the projections alone may be depended upon for keeping the hook in place.

The size and upward extent of projection 28 may be varied, as desired, as well as its form. This upwardly extending portion 30 of this pro jection need only be of such length that when the hook is shifted into the position shown in Figure 4 a portion of it extends above the hole l2. This portion may be longer or thicker or shorter or thinner, all depending upon the weight to be supported by the hook. Also, the slot 48 in the lower projection 3% may vary in depth, so long as it permits the hook to be shifted downwardly sufficiently to permit screw 4-! to pass through the hole I2.

Preferably both projection 28 and projection 38 will be proportioned for insertion in openings 12 of the same dimensions since this makes for a maximum of shift-ability. If desired, however, the two projections may be designed for association with holes of different sizes, in which case the pairs of openings in the supporting structure with which the hook is to be used will be proportioned likewise.

The advantages of the invention disclosed herein are believed to be clearly apparent from the foregoing description. Thus, although the hook is firmly secured when it is fixed in a pair of adjacent holes, it may be very readily shifted to some other point merely by loosening the screw 44 and withdrawing it as described. The number of positions to which the hook may be shifted wi1l,.of course, depend upon the number of. pairs of adjacent, holes provided for the purpose; It will be obvious, of course, that where it is desired a sufiicient number of holes may be provided to shift the hook to substantially any desired position on the supporting structure.

As will be clear to all who have had experience with positioning of materials upon shiftable hooks, it is a decided disadvantage of such hooks that they are ordinarily very easily dislodged during the operation of placing articles upon them or removing them. This disadvantage is entirely absent from the hook of the present invention which cannot be dislodged during or dinary usage.

Preferably the panel is formed of sheet-metal although it may be formed of any desired material having sufiicient strength. The hook may be conveniently formed of cast-iron although it is also within the scope of the invention to form the hook of any other material and in any other way which results in a hook having suftlcien strength for the purpose involved.

It is apparent that many widely different embodiments of the invention may be made without departing fromthe spirit and scope thereof, and therefore it is not intended to be limited except as indicated in the appended claims.
