FIGS.

United States Patent 6 M 3,288,311 SKID Donald P. Beattie, 17 Wildwood, Kirkwood, Mo. Filed June 12, 1964, Ser. No. 374,655 Claims. (Cl. 214-105) This invention relates to so-called skids, and more particularly to a collapsible skid useful for the stacking of steel tubes or the like.

Among the several objects of the invention may be noted the provision of a skid adapted for use in multiples to form a cradle for holding a stack of steel tubes or the like, the skid per se being collapsible for convenient storage, shipment and handling; the provision of a skid such as described which is of such construction as to permit tight banding of a stack of items cradled in a plurality of the skids by application of steel strapping or the like around the skids and drawing up of the strapping; the provision of skids such as described useful upon removal or the strapping to form an open-topped cradle or bin for holding the stacked items and allowing for removal of items from the stack; and the provision of a skid such as described which is of low-cost construction and easy to use. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being in dioated in the fo lowing claims.

In the accompanying drawings, in which one of various possible embodiments of the invention is illustrated,

FIG. 1 is a view in elevation showing several skids constructed in accordance with this invention supporting elongate items such as steel tubes;

FIG. 2 is an enlarged view from the right 1; and

FIG. 3 is a view showing a skid of this invention in the collapsed position.

Corresponding reference characters indicate corresponding parts through-out the several views of the drawings.

Referring to the drawings, a skid of this invention is designated in its entirety by the reference numeral 1, and is shown to comprise a bottom bar 3,

side bars

5 and 7 and a top 'bar 9. The skid 1 is adapted to receive elongate items 11, such as steel tubes or the like, with the tubes resting on the bottom bar 3 and positioned between

side bars

5 and 7. Top bar 9 is then placed on top of the tubes 11 and held in place by fastening means 13, such as a strap or band of steel or the like having its ends connected as shown at 14 with commercial banding tools. Multiples of the skids 1 are employed for supporting items of substantial length as illustrated in FIG. 1. The

bars

3, 5, 7 and 9 can be constructed of various materials, lengths of wooden two-by-fours having been found acceptable for these members.

An L-shaped plate or hinge member 15 has a relatively long arm 17 secured to side bar 5 by rivets 19'. Hinge member 15 also has a relatively short arm 21 positioned at one side of one end of bottom bar 3. Arm 21 has an elongate slot 23 which extends longitudinally along the arm portion 21 and transverse to the length of side bar 5. A rivet or pivot pin 25 is secured in bottom bar 3 and passes through or is received in slot 23. With this mounting, the side bar 5 is slidable relative to the bottom bar 3 in the direction transverse to the length of the end of FIG.

Patented Nov. 29, 1966 side bar 5, and the side bar 5 can be swung about rivet 25 fromthe erect position shown in FIG. 2 to the collapsed position shown in FIG. 3.

Another L-shaped plate or hinge member 27 has a long arm 29 secured to side bar 7 by rivets 31, and a short arm 33 positioned at the side of the other end of bottom bar 3. An elongate slot 35 in arm 33 extends longitudinally along arm 33 transverse to the length of bar 7. A rivet 37 is mounted in bottom bar 3 and is received in or passes through slot 35 so that side bar 7 is movable or slidable with respect to the bottom bar 3 in the direction transverse to the length of the side bar 7, and the side bar 7 can be swung about rivet 37 from an erect position (FIG. 2) to a collapsed position (FIG. 3). FIG. 1 shows two of the hinge members 15 located on opposite sides of the side bar 5 and bottom bar .3 with the

rivets

19 and 25 passing entirely through the side and bottom bars to mount both hinge members 15. In a similar manner, two hinge members 27 can be provided and connected to side bar 7 and bottom bar 3.

Slots

23 and 25 are sufiiciently long and are located in

hinge members

15 and 27, respectively, so that

side bars

5 and 7 when in at least one position relative to bottom bar 5 may be swung from the erect position of FIG. 2 to the collapsed position of FIG. 3 by movement about

pivots

25 and 37. When in the erect position, the lower ends of

side bars

5 and 7 engage the top of bottom bar 3 to limit pivotal movement of

side bars

5 and 7 outwardly or away from each other, such resulting from the binding engagement or contact between the lower ends of the side bars and the top surface of the bottom bar.

Slot 35 in hinge member 27 is spaced from the side bar 7 (offset from the central plane of the side bar) a greater distance than the spacing between slot 23 and side bar 5, the slot 35 being approximately one side bar width farther from bar 7 than the slot 23 is from bar 5. This permits the

side bars

5 and 7 when collapsed to be in substantially parallel relation with side bar 5 nested under side bar 7 as illustrated in FIG. 3.

When it is desired to collapse the skid 1,

side bars

5 and 7 are slidably moved to a position such as shown in FIG. 2 and side bar 5 is then swung downwardly or to the right as viewed in FIG. 2 to move the side bar 5 from the erect position of FIG. 2 to the collapsed position of FIG. 3 wherein the side bar 5 lies on top of the bottom bar 3. In a similar manner, side bar 7 is swung from the erect position of FIG. 2 to the collapsed position of FIG. 3 on top of the side bar 5. The free end of side bar 5 is tapered as shown at 38 so that it will not interfere with pivotal movement of side bar 7.

In using the skid of this invention, the

side bars

5 and 7 are moved to the erect 'positon of FIG. 2 to form an open topped bin or cradle and elongate items 11, such as steel tubes or the like, can then be placed on the bottom bar 3 between

side bars

5 and 7. When the items 11 have a substantial length, the skids 1 are used in multiples and located in spaced relation to each other as illustrated in FIG. 1. When it is desired to ship or transport the items 11 in skids 1, top bar 9 is positioned on top of the elongate items 11 and is held in position by passing a metal band or strap 13 around the bottom bar 3,

side bars

5 and 7, and top bar 9 and drawing up of the strapping. As the strapping is :drawn taut,

side bars

5 and 7 move inward toward one another, while remaining erect,

as permitted by slots 23. The ends of the strap or band 13 are then fastened as shown at 14 with commercial banding tools. The skids 1 and elongate items 11 then become a substantially unitary package which may be easily shipped with-out loss of items 11 from the skids. Band 13 is preferably tight-1y fastened in place to maintain some force or pressure on the elongate items 11 and prevent relative axial movement therebetween.

By removing band 13 and top bar 9, the skid may be used as an open-top bin until all of the elongate items are removed. The skid can then be collapsed to the position shown in FIG. 3 and returned to the supplier of the elongate items or stored. Collapsing of the skids facilitates shipment, storage and handling of the skids. Use of the skid as a bin eliminates the need for moving the elongate items from a shipping crate to a temporary storage bin, thereby saving the purchaser time and expense. The skids 1 can be made inexpensively due to the few parts required and the fact that most parts can be made from stock items out to the desired size.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.
