Davis, Fort Salonga, N.Y. Filed Mar. 21, 1968, Ser. No. 715,107 Int. Cl. A44b 11/25 US. Cl. 24-75 4 Claims ABSTRACT OF THE DISCLOSURE Cargo tiedown net, made up of webs to fit over a load on a pallet or over an igloo on a pallet, with buckles for taking up and adjusting web length and connectors for connecting lengths of web together and for connecting ends of web to the pallet.
The objects of this invention have been to provide a combination of fastenings for securing a cargo net over a load, such as ordinarily confined in an igloo type of container and which could be readily selected, applied and adjusted to fit the particular load.
The drawings accompanying and forming part of this specification illustrate the general combination and some of the various forms of connectors constituting the invention, but it will be appreciated that as this illustration is primarily for purpose of disclosure, the actual structure employed may be variously modified and changed; all within the true spirit and scope of the invention.

FIG. 1 is a side elevation of one of the web adjusting buckles employed in the combination first illustrated.
FIG. 2 is a top plan view of the same.
FIG. 3 is a side elevation of this device showing the web holding lever lifted to release the grip on the web.
FIG. 4 is a side elevation of this form of connector modified to have a hook form of anchorage means instead of a simple bar connection for the webbing, as first shown.
FIGS. 5 and 6 are a side and a broken plan part sectional view of a modified form with the hook as a flat plate having integral pivot lugs engaged in the sides of the supporting lever; the sectioned part of FIG. 6 appearing as on the line 66 of FIG. 5.
FIG. 7 is a side elevation of another modified form of the supporting and operating lever and FIG. 8 is a plan view of the same.
FIGS. 9 and 10 are a side elevation and a top plan view of a further modified form of the invention.
FIGS. 11 and 12 are plan and side views respectively of another form of web length adjusting buckles.
FIG. 13 is a perspective view of a simple form of the buckle with a pivoted disconnecting plate.
FIG. 14 is a broken detail showing end connector construction for connecting a web with the pallet.
FIG. 15 is a broken plan of a connector for a number of angularly related webs.
FIG. 16 is a side elevation showing how the last illustrated form of fastener may be used for take-up or reeving purposes, broken lines indicating how parts are connected.
FIG. 17 is a plan view of an adjustable form of web attaching means for the connector plates.
FIG. 18 is a top plan view of a further modified form of the invention, showing the two plates of the connector joined together and locked in that relation by a releasable latch member.
FIGS. 19 and 20 are plan views of different forms of connector plates.
FIG. 21 is a detail part sectional view showing how an end fitting may be secured to a web so as to carry pull in either direction.
FIG. 22 is a broken sectional detail on line 2222 of FIG. 15, showing how the web may be adjustably attached to a connector plate by looping the same through parallel slots in the plate.
FIG. 23 is a detail plan of one of such slotted connector plates.
In FIG. 1A there is shown an igloo 40 of conventional design on a load supporting pallet 41, over which is secured a web net 42.
Buckles are provided for adjusting the length and taking up slack in the vertical and horizontal lengths of web forming the net.
FIGS. 1, 2 and 3 show these buckles as made up of just a single U-shaped lever of parallel sides 10, connected in that relation by a back wall 11 and a web clamping bar 12, slidable in slots 13 in said sides toward and away from said back wall.
The sides of this U-shaped frame are connected by a cross bar 14 or other anchorage means for one web length 15, and the companion length of web 16 is looped at 17, about the slide bar 12, where under tension it will be gripped between said bar and back wall.
Additional holding is gained by an angularly extending flange 18 on the lower edge of the back wall serving under tension of the web as a clamping foot bearing down on the top of the free, handle bearing run 19 of the web.
Means for lifting the lever and rocking the same about the anchorage member 14 is provided in the form of a handle 20 extended angularly away from the upper edge of the back bar or wall 11.
FIG. 3 shows how with utilization of the handle 20, as a lever, the body of the connector may be rocked about the anchorage at 14 to lift the holddown foot 18 from pressure engagement with the web and to permit the clamp bar to slide down away from the back wall to release the loop of web, enabling such web to be freely adjusted with the connector in this upraised position.
The anchorage means connecting the free ends of the lever may be in various forms to suit difierent requirements.
Thus in place of a simple cross bar 14, the end anchorage may take the form of a hook 21, FIG. 4, pivoted on a stud 22, riveted to the ends of the side parts 10.
This view also shows how the handle 20 may be further extended to give greater leverage.
FIGS. 5 and 6 show a hook structure 23 in the form of a flat plate having integral end extensions or lugs 24 pivotally engaged in bearing openings in the sides of the lever; the reduced ends 25 of such lugs being headed over at 26 against the confining washers 27.
FIGS. 7 and 8 illustrate a simplified form of lever construction in which the side walls 28 of the lever are integrally connected at both ends by the back wall at 29 and at the front by a cross bar 30, forming an integral extensioii of the side walls and a terminal for the length of webhing 15 looped about the same.
In this form of the invention, the leverage handle 20 is shown extended from the lower edge of the back wall 29.
FIGS. 9 and 10 illustrate an embodiment consisting of a frame of parallel sides 31, connected in spaced relation at opposite ends by cross bars 32, 33 and a lever 34 pivoted on the frame at 35 and carrying the slide bar 36 in cooperative relation with the clamping abutment forming back wall 37.
Further modifications are possible:
FIGS. 11 and 12 illustrate a variation of adjustable connector similar to that shown in FIGS. 7 and 8, but with the addition of a fixed abutment bar 38, cooperable with 3 the sliding bar 12, to hold a web loop, this fixed bar being inserted through a hole in one side of the frame and peened over at the opposite end.
FIG. 13 illustrates a connector in the form of a flat plate 39, having a fixed bar 40a, about which the web is looped and to which there is pivoted at 40', an offset head piece 43, to be engaged through a T-slot 44, in a disconnect plate 44', to which the end of the companion web piece is attached.
FIG. 14 shows how the webs may carry end fittings 45, engageable with tracks 46, on the pallet as illustrated more fully in co-pending application Ser. No. 647,988 filed June 22, 1967.
FIG. 15 shows how a number of angularly related webs may be joined together by a single connector plate 47, having L-shaped slots 48, to receive the end fittings 49, of the several webs.
These L-shaped slots have joined long and short slot portions and the web end fitting has a head 50, wider than the narrow slot, so that it must be entered through the wide slot, after which the fitting may be partially rotated to locate the narrower neck of the fitting in the shorter length of the slot.
Under stress this coupling will remain in connected relation, but if desired, a latch 51, or equivalent may be mounted on the plate to restrain and hold the end fitting in this connected relation.
FIG. 16 shows how connected webs with an extra length between the webs may be reeved with this type of fitting.
It will be evident from the foregoing that the several forms of fasteners illustrated may be combined in many different relations to meet the requirement of the loading and other factors.
FIG. 17 shows one form of adjustable means for connecting a web with a plate; the plate 55 in this case being one of the slotted plates, having lugs 56 struck up from an elongated portion of the plate, supporting a pin 57 for an adjustable web holding cam lever 58.
FIGS. 16 and 18 illustrate a modified form of the present invention in which each of the cooperatively engaging plates 65 and 66 is provided with web attaching means at one end, shown as slots 67 and 68, through which the loops 69 and 70 of webs 71 and 72 are secured.
While this simple stitched form of attachment is generally preferred, other non-adjustable or adjustable forms of attachment may be employed; the invention contemplating such various forms of attachment means.
Plate 65 is shown as having an L-shaped slot therein, at the end opposite the web attachment means, made up of angularly related convergently connected legs, one, numbered 73, extending longitudinally of the plate and longer than the shorter transversely extending leg 74 and with the edge of the included angle on a gradual curve 75, leading from one leg into the other.
Plate 66 is shown as having an extended neck 76 at the end opposite the web attachment means thereon, of a width slightly less than the length of the shorter leg 74, bent back at an angle to the plate and carrying in offset parallel relation an enlarged head 77, of slightly less width than the length of the longer leg 73, but longer than the shorter leg.
This construction provides for the interlocked connection shown in FIGS. 16 and 18, with the angularly extended narrower neck portion 76 disposed in the short leg and the wider head portion 77 located parallel, at the back of the slotted plate, overlapping both legs of the L-shaped slot.
In engaging the two parts, the headed plate is turned at an angle to register the head with the long side of the slot and after passage through this part is turned about the convexly curved edge 75, to place the neck in the short side of the slot, where, under tension the parts will be held securely interlocked.
The parts are uncoupled by reverse operation, as will be clear from the broken line indicated in FIG. 16.
If desired, a latch may be provided for positively locking the parts in connected relation, as shown in FIG. 18, where there is illustrated a latch member 78, pivoted on the slotted plate in position to be swung from a noninterfering to a position for holding engagement with the neck portion of the headed member.
The connector has many different uses for securing cargo or other purposes.
FIG. 16 shows how a connector may be used for reefing or reducing the effective length of the webs, which in this case are shown connected by a loop 80 of excess web.
FIGS. 1A and 15 show how a number of angularly related webs may be connected to a single slotted plate 47, carrying the attachment means for two or more angularly related webs, and provided with two or more angularly related L-shaped slots to receive the headed plates on the ends of other angularly related lengths of Webbing.
FIG. 17 shows one form of adjustable means for connecting a web with a plate; the plate in this case being one of the slotted plates, having lugs 56 struck up from an elongated portion of the plate; supporting a pin 57, for an adjustable Web holding cam lever 58.
FIG. 19 illustrates a connector plate having an L-shaped slot 48 at one end and parallel slots 81 at the opposite end through which the webbing may be looped and adjustably held, as indicated more fully at 82 in FIGS. 15 and 22.
FIG. 20 shows a headed form of connector plate like that shown at 49 in FIG. 15, but having in addition one of the L-shaped slots 48 and a web receiving slot like that shown at 68 in FIG. 18, so that it may be used as in FIG. 18 and have webbing detachably connected by angular slot or fixedly connected by the cross slot.
FIG. 21 shows how a terminal fitting as represented by a slotted plate 83 may be sewed into a line for pull in either direction, by having a loop of webbing 84 passed through the slot, stitched together at 85 and opposite ends stitched fiat at 86, 87 over the line webbing 88, enabling the attachment to bend freely in opposite directions to take the pull applied either way.
FIG. 23 illustrates one of the headed plate members such as 66 in FIG. 18, modified by having parallel cross slots such as those at 81, FIG. 22, for adjustable attacha ment of the web thereto.
