Definitions

• This invention relates to a cargo restraining device and, in particular, to a device for storing and restraining barrelshaped- containers such as drums, to prevent damage during transportation thereof.
• Van Gompel which application is commonly assigned with the present application, a device for restraining a cargo load has been described, which includes an elongated
• a floor piercing element is movably mounted on the floor con ⁇ tacting member adjacent to the rearward end thereof, and is normally disposed to pierce the floor when the floor contacting member is under load, to restrain movement of the load during transport.
• United States Patent No. 1,142,088 describes a load supporting rack specifically designed for use with hand trucks and having an open frame base and end wall with diagonal braces joining the lower end of the end wall to the base.
• United States Patent No. 1,559,827 describes a freight anticreeping device including a metal plate for supporting cargo, cleats on the lower surface of the plate for gripping the floor, and a projection or lug on the other surface to which the cargo is secured.
• United States Patent No. 1,638,612 describes a cargo shipping device in which the cargo is braced on a platform and rigidly held in position.
• United States Patent No. 2,420,640 describes a de- mountable pallet crib for storing and handling pallets. Essentially, the pallets are enclosed in a frame which is assembled about the pallets. Between each end frame and an adjacent cheek frame interlocking means are provided so that the crib frame can neither bulge at the corners, nor collapse when heavily loaded.
• United States Patent No. 4,014,435 describes a collapsible rack for glass sheets, which has a base de- tachably secured to a pair of L-shaped supports, while a pair of struts is detachably secured to vertical
• a cargo restraining device suitable for restraining barrel- shaped containers or drums, which includes a platform at least the loadbearing part of which is flat, and which is spaced from the underlying support- ing surface or floor, by horizontal supporting members which extend the length of at least the flat portion of the platform, so as to provide a raised deck for the containers.
• a platform At one end of the platform, an upright or vertical frame is connected to the supporting members, to restrain the containers from falling from the platform.
• the other end of the platform can be rounded over to define a snub-nose; or alternatively the other ends of the horizontal supporting members can project beyond the flat portion of the platform and be rounded into snub-nosed portions.
• the chimes or rims of the drums tend to flow around the snub-nose (or snubnoses if defined at the supporting members) without any signifi- cant damage.
• the containers instead of falling off when moved, gently slide about and off the snub- nosed portion or portions; and no abrupt discontinuous
• floor piercing members are provided, which are normally oriented to the floor piercing position, and firmly hold the platform in place.
• a strap may be placed around the containers, and secured at the ends to the upright frame, to further restrain movement of the drums on the platform.
• a plurality of drums may be vertically loaded into a truck trailer, box car, or the like, with the first loaded row being placed against the front wall of the trailer.
• Plywood partitions or the like can be placed between some or all of the successive rows to space the rows and limit row-to-row drum contact.
• one or more of the present drum restraining devices are loaded with drums, and the resultant assembly or assemblies positioned against the plywood sheet opposed to the last row of drums. The devices are held in place by the floor-piercing members gripping the floor.
• the containers are securely held, yet some movement is permitted; and in the unlikely event of pronounced movement, as when a strap breaks, the containers can gently slide over or "flow" about the rounded snub-nosed end or ends of the restraining device without any serious damage to the said containers.
• a still further obejct of the invention is to pro ⁇ vide a cargo restraining device for the transport of drums containing hazardous or explosive materials, which is easy to load and prevents damage to the drums during transport.
• Another object of the invention is to provide a cargo restraining device for the transport of -drums containing hazardous or explosive materials, which requires no associated braces or enclosures.
• a further object of the invention is to provide a cargo restraining device for the transport of drums containing hazardous or explosive materials, which is easily transported, and readily placed for further transport in a vehicle.
• Figure 1 is a sectional elevational view of a loaded truck trailer showing a drum restraining device in accordance with the present invention in use; part of the drawing is schematic in nature;

• FIG. 2 is a perspective view of a drum restrain ⁇ ing device in accordance with the present invention.
• Figure 2A is a perspective view of a further em ⁇ bodiment of a drum restraining device in accordance with the present invention.
• Figure.3 is a view generally similar to that of Figure 2, showing drums in place on the drum restraining device;
• Figure 4 is a side elevational view of the drums held in place on the drum restraining device, as shown in Figure 3, but with the restraining strap in place;
• Figure 5 is a detail view with parts broken away, of the floor piercing element in Figure 4, the phantom lines show the toothed pivotal member in its retracted position relative to the floor;
• Figure 6 is a detail view taken generally along the line 6-6 of Figure 5.
• the drum retaining device 10 shown in Figures 2 and 3 has a deck or plat ⁇ form 12 on which drums 14 are placed ( Figure 3).
• An upright or vertical frame 16 is joined to the rear end of platform 12.
• This frame generally comprises a plurality of spaced posts 18 which extend upwardly from platform 12 and are supported by cross-brace mem ⁇ bers 20 and 22.
• Platform 12 is supported and spaced from the floor by a plurality of horizontal stringer-like members or legs 24 to which the platform is attached.
• the forward ends of the legs 24, which project slightly from plat ⁇ form 12, are rounded into snub-nosed portions 26, as can be seen in Figures 2, 3, and 4, so that the drums, if
• the device 10a primarily differs from device 10, in that instead of including rounded portions 24a (as in Figure 2), the members 24 each terminate at forward ends 25, and the platform 12 is in this instance formed into a rounded front portion 27 along its entire front edge. In this construction the rounded portion 27 is therefore continuous, and thus all the advantages of the rounded portions 24a are retained, and indeed enhanced.
• the device 10a also differs from device 10 in that an enlarged cross-member 29 replaces member 22 ( Figure 2) to provide greater stability and strength.
• device 10a is substantially identical to device 10, and the ensuing description may be regarded as applicable to either embodiment.
• At least the outer pair of legs 24 i.e. the leg 24 and 24a
• each of the said outer legs are formed 8 -
• a filler plate 26 extends across the channel to form a box section portion 30, as best shown in Figure 6.
• Each box section portion 30 of the respective outer leg 24 supports a pair of spaced pivotal members 32 to thus provide a total of eight (8) such members on the drum restraining device 10.
• the pivotal members 32 are each disposed on the legs 24 intermediate the leg and an outer support member 34 secured to the leg 24.
• the mem ⁇ ber 32 is pivotally disposed on a pin or bolt 36 which extends transversely through aligned holes in the box section 30 and the outer support members 34.
• An inver- ted, generally J-shaped bolster plate 38 is secured on each side of leg 24 between the leg and corresponding outer support member 34 in radial alignment with the corresponding pivotal member 32.
• the pivotal member 32 includes an upper arcuate portion 40 which is at a given radial distance from the pivot axis and is rotatable relative to the bolster plate 38, and a diametrically opposed toothed portion 42 which is at a substantially greater radial distance from the pivot axis.
• Diametrically opposed, parallel por- tions 44 and 46 extend between the arcuate portion 40 and the toothed portion 42. Due to the generally larger size and greater radial distance from the pivot axis, the toothed portion 42 will normally assume a downwardly disposed position as generally shown in Figure 5.
• the leg 47 of the bolster plate 38 generally pre ⁇ cludes counter-clockwise movement of the pivotal member 32, as viewed in Figure 5. As generally shown by phan ⁇ tom lines in Figure 5, pivotal member 32 is clockwise rotatable at least until the straight portion 44
• the teeth 50 with vertical or near vertical rearwardly facing edges will substantially maintain position to keep the drums from moving toward the rear — the teeth 50 will thus keep the device 10 from moving toward the - 10 -
• a pair of retaining devices 58 and 59 loaded with drums are seated in the trailer to secure the integrity of all drums in the forward direction between the retaining devices and the front end 51 of the trailer 60.
• one or more plywood or other temporary sepa ⁇ rating walls 53 are mounted between rows of drums to assure proper spacing and minimize the possibility of damage in the tightly packed drums.
• retainers 10 may also be used to generally preclude lateral movement as well.
