18 Claims. (Cl. 105"369) The present invention relates to improved loading apparatus for holding freight articles of different types in vehicles or storage spaces, and more particularly'to improved equipment of this nature having certain parts which are built into or combined with a vehicle, such as an airplane, a ship, truck, trailer, railway freight car, or other storage space, and having certain other parts which are adjustably and variously co-operable with the built-in parts, the several parts of the equipment co-operating to hold (that is, for example, to brace, support or carry, space, wedge or provide shelves, partitions or bins for) a wide variety of freight articles. In certain of its aspects, the present invention provides improvements upon the invention described and claimed in applicants copending application Serial No. 469,719, filed December 21, 1942, now abandoned, as a continuation in part of application Serial No. 434,357, filed March 12, 1942, now abandoned but replaced by copending application, Serial No. 740,330, filed April 9, 1947, as a continuation of said application, Serial No. 434,357 said application 740,330 now being Patent No. 2,519,846.

Objects of the present invention are to provide a freight-loading system of the above generally indicated type, which employs relatively light weight, readily maneuvered loading members,

which may be economically manufactured and installed in the associated storage space and which may be readily adjusted to accommodate different loading conditions; to provide such a system employing tubular holding members, at least certain whereof comprise two or more telescopically related elements which are freely adjustable as to length and which may be fixed together in desired adjusted positions; to provide such a system embodying improved means for interconnecting a related pair of tubular members, said means including an adjustable jaw structure of improved construction; to provide such a system wherein the tubular members are of relatively thin-walled type and consequently are sufficiently elastic so that they can flex to accommodate distortions of the associated storage chamber due, for example, to the condition of the highway or road bed over which the associated vehicle is operating; and to provide such a system wherein the loading members are of relatively small cross section, adapting them to be readily threaded through meshed material, such as netting, which may be used in forming bulkheads and the like.

Other and more detailed objects of the invention appear in the following description and in:

the appended claims and in the drawings,

It will be appreciated from a complete understanding of the present invention that, in their more generic aspects, the improvements thereof may be embodied in freight-loading systems of widely varying types, intended for use in connec-"' tion with various types of storage chambers. The improvements are particularly adapted to be embodied in relatively light weight, easily handled and adjusted loading members, having a degree of flexibility which particularly adapts them for use in connection with trucks and trailers. The disclosure of the invention herein with particular reference to such an application thereof is, how 1 ever, to be taken in an illustrative and not in a limiting sense.

Referring to the drawings, particularly Figs. 1

through 8, the apparatus is built into a storage space or chamber which may be, for example, the body of a truck or trailer, which body is pro-' vided with a usual floor l0, side walls 12, and roof structure l4; To illustrate'the adaptability of the invention to irregularly shaped storage spaces,

the just-mentioned chamber is provided near one end with a stepped portion having an upper surface It and a vertical end surface l8. Specifically, Fig. 1 shows the interior of a trailer looking towards the front, in which lB-l 8 is the kickup or raised portion which accommodates the fifth wheel assembly. A variety of differently dimensioned and shaped freight articles I are illustrated as beingstacked in the storage space and as being held in place therein, in this instance, by bulkheads composed of a plurality of cross members 20.

In the illustrated embodiment, the freight-loading members comprise, in addition to the justmentioned cross members 20, a plurality of horizontally arranged loading members or side rails 2|, 22, and 23 and a plurality of vertically arranged loading members 24. In the preferred practice of the invention, the side rails are more or less permanently applied to the co-operating supporting parts of the chamber and may, in fact, constitute the structural members which form a part of, or act to reinforce, the-chamber. As shown :further, all of the members 20, 2|, 22, 23, and :24 are tubular in form. Generically, a variety of tubular sections, such as square, hexagonal, or other noncircular sections may be employed, if relative rotation between the hereinafter. described telescopic sections is not required. Preferably, and as shown, the tubular members are cylindrical enabling both lengthwise and rotative movements between the telescoped sections. All of these members may be, and preferably are, formed of relatively light weight metal, such as aluminum or the like, having sufiiciently resilient characteristics to enable them to flex to a reasonable extent so as to accommodate the structure to distortions of the freight chamber which are caused, for example, by uneven road conditions or the like. The vertical members 24 are secured to the side rails by the hereinafter described adjustable jaw structures which embrace, but do not completelysurround, such side rails. Members 2|, '22, and '23 are, accordingly, secured to the chamber walls by attachingv elements which do not interfere with the application thereto of members 24 at any desired point therealong.

.More particularly, as viewed in Figs. 1 and 2, each upper rail 2i is provided with a plurality of attaching brackets 30 which are distributed along the length thereof. Each bracket 30 is of generally Z shape, having a vertically disposed bight 32 and legs 34 and 36. Leg 34 is secured, along its lower edge 34a, to the upper surface of the co-operating rail 2!. With this relation, the bight 32 is disposed above .and out of the way of the body of the rail, so that it does not interfere with movement along .the latter of the jaws 36 associated with the co-operating vertical members 24. The remaining leg 36 extends downwardly somewhat with respect to the bight'32 and is adapted for connection, as by one or more bolts 38, to the wall structure l2. As will be appreciated, the above described bracket structure is particularly suitable in cases where the rails 22 are located somewhat below the roof structure or somewhatabove the floor structure.

In the present instance, the lower ,rails 22 and 23 are secured directly to the sub-floor or framing structure underneath the wear surfaces designated l and i6, and so occupy recesses or channels between the chamber walls and the side of such wear surfaces or heavy duty flooring llll.6. The jaws 36 require little radial or lateral clearance in operation, so that the channels 25 may be relatively narrow. As illustrated, rails 2223 are only partly recessed. If desired they may be completely recessed to realize the maximum of usable freight loading volume, and to prevent injury to or interference between the load and such recessed rails. As shown, the rails 22 and 23 are secured in place by passing bolts such as 40 through the corresponding supporting surface 4! as well as through the structural member 43 (Fig. 3).

It will be observed that the vertical spacing between rails 2i--22, on the one hand, and rails 2l23, on the other hand, are different. There may be cases, also, in which members 2 i2223 may be nonparallel, as in accommodating irregular vehicle shapes. The hereinafter described telescopic :feature of uprights 25 is peculiarly advantageous in permitting the use of interchangeable parts to accommodate a wide range of spacings.

The above discussed lack of parallelism or different spacing arises from the design of the vehicles or other storage space. In addition, as a practical matter, there are static errors or permanent manufacturing inaccuracies whereby two elongated spaced apart surfaces will not be truly parallel. Also, similar conditions arise dynamically due to the weaving of the vehiclein transit. In all of these cases, the telescopic feature of members, such as 23-2 (and in some cases, even rails 2 l2223) is of practical value.

Structural'ly, the vertical members 2 and the cross members 2.6 may be identical with each oth-.. er and, in fact, may be used interchangeably since the lengths thereof are readily adjustable. This interchangeability is of substantial practi-. cal importance to the manufacturer in that it reduces the number of different parts which he must arrange to produce; and to the user in that he does not need to exercise care in selecting the proper part for an upright or cross bar, since he may, with a given number of parts, provide for more different loading conditions. Stated otherwise, a smaller number of parts will suffice to adequatelyequip a vehicle. A description of, for example, one of the members 29 will consequently serve as a description of the members 24.

Referring particularly to Figs. 4 through 8, each number as is made up of two telescopically related tubular portions 26a and 2%, both being illustrated as of circular section. The fit between these members is such that they may be freely slid lengthwise and rotated relative to each other. A limit to lengthening adjustment is afforded in this instance by providing an end plate 50 which is secured at the end of each innersection. Each plate 50 is apertured as indicated at 52, so as to loosely pass a connecting rod 54. Each rod '54 also passes loosely through a second motion-limiting plate 55 which may be secured in any suitable way within the body of the cooperating outer member 261). With this relation, it will be appreciated that a limit to lengthening movement is reached when plates 59 and 55 are spaced apart far enough to encounter the nuts 58 and G6, or other stops, formed on rod 54. A limit to collapsing movementon the other hand is afforded when plates 55 and 55 abut each other. It will be appreciated that, by locating each plate 56 relatively near the outer end of each outer section 29b and giving the rod 51! a length approximately equal to the length of section 262), a range of adjustment approximately equal to the length of the section 2% may be provided. Such a range of adjustment makes it readily possible to use members 20 and 24 interchangeably as verticals and as cross members.

In assembling the two sections 20a and 2% together, it will be understood that plate 50, with rod 54 already fitted thereto, may first be secured in the end of section Zea. Thereafter the assembly comprising section 260;, plate as, post 5 and plate 56 may be advanced into the outer section 201), and pushed therealong until plate 55 reaches the desired position lengthwise of section 2%. With the parts thus properly located, the plate 56 may be secured in place within section 2% as by spot welding, passing one or more mounting studs through corresponding ones of openings til into plate 56, or otherwise.

In order to enable end-to-side connections between individual vertical and cross members, each member 28 is provided throughout its length with a plurality of attaching means. As shown, these attaching means take the form of relativesmall, slightly elongated openings t8 which pass through the walls of each section 2911 and b. The hereinafter described jaws are ar ranged to co-operate with circumferentially spaced pairs and groups of the attaching openings. Specifically, each section 26a and 2% is provided with four rows of equiangularly spaced openings 60 which enable the jaws to be connected thereto at any one of four positions spaced approximately 90 apart. As noted below, the slightly elongated shaping of the openings facilitates the application of the jaws 36 to the members 20. Also such shaping enables some canting of each jaw with respect thereto. Considering Fig. 1, for example, this canting permits members 20 to be canted somewhat in both horizontally and vertically disposed planes. The canting operations serve to accommodate the structure to irregular loads or to loads which, for example, do not extend entirely across the vehicle, all as will be understood.

Each jaw 36 is made up, in the illustrated embodiment, of a pair of relatively movable, arcuately shaped jaw elements 62 and 64. The inner or bearing surfaces of these jaws are struck on radii approximately equal to the outside diameter of each inner section 20a, so that when they embrace such an inner section (Fig. 4) they snugly fit the outer surface thereof. Each jaw element is provided on its inner surface with a plurality of attaching means which, as shown, take the form of substantially circular bosses 66. These bosses project radially inwardly a distance approximately equal to the wall thickness of each outer section 201), so that when the jaws (Fig. 8) are fitted over such outer section, the bosses will not be interfered with by an imperforate portion ofthe periphery of the inner section 2841. Thus the jaws 36 can cooperate with an outer section 20? independently of whether its openings cc are aligned with the openings (iii in the cooperating section 20a.

' Each jaw element 62 is secured as by spot welding, as indicated as 10, to a rearwardly extending body portion 12. In the case of a jaw at the end of .an inner section 26a, each jaw portion 12 may, and preferably does, constitute a semicircular extension of such section 20a defined by cutting away the latter along the radial line 14 and along the axial line 16. In the case of a jaw formed in the end of an outer section 26b, the semicylindrical body portion 12 may be provided at the end of a tubular extension 13 which may be welded or. otherwise securedwithin the extreme end portion of the section 20b, as shown in Fig. 4A.

the spacin wherebetween, as viewed in Fig. 5;

is sufiicient to snugly but freely receive the previously mentioned boss 18. Bosses 18 and 84 are provided with aligned apertures which receive a pivot pin 36, which may have a drive fit within either the boss '58 or the two bosses 84. Pin 86 thus serves to pivotally interconnect the two jaw elements 62 and 64, and allows sufiicient spread ing thereof to enable them to be freely passed over either an inner or an outer section 29a or 2%.

An important feature of the present invention resides in the provision of means to lock the jaw" members together when fitted over either an inner or an outer section. As illustrated, this looking is accomplished by a sleeve 9!] which is slidable lengthwise of the jaw assembly from the locked position shown in Figs. 4 and 8 to a retracted position spaced sufficiently far from the jaw elements to permit the necesary pivoting of the latter. Preferably, and as shown, detent means are provided to releasably hold the sleeve 9!) in its locking position. The. detent structure comprises a ball 92 which is biased outwardly by a spring 96 fitted in a recess provided in the boss i8. The material surrounding the ball is peened over slightly after insertion of the latter to pre vent escape of the ball from the detent pocket,

in accordance with familiar practice.

, In order to enable it to lock the jaw elements in either of the positions of Figs. 4 and 8, sleeve Si! is provided with an axially extending radially projecting recess or groove 96, which co-operates with a correspondingly shaped rib 98 formed on the body 82 associated with jaw element 64. Sleeve 96 is both turnable and slideable relative to the jaw assembly. Thus, when the. jaws are fitted over an inner section 26a, sleeve as can be turned to the rotative position shown in Fig. 5, in which rib 98 is out of registry with groove 96. When so positioned, sleeve 99' obviously holds the jaw members relatively close together, forcing the bosses 6% into the openings Gil in the inner section Zea. On the other hand, when the jaw members are fitted over an outer section 20b, sleeve. se is first turned to a rotative position in which rib 98 is lined up with groove es and thereafter sleeve 98 is slid lengthwise of the jaw assembly from the retracted position to the locking position. The proportioning of the rib S3 and the groove is such, as will be understood, as to enable the sleeve 93 to hold the jaws in relatively snug engagement with the surface of an outer section 2%.

It will be noticed that when the jaws S2 and 6d are separated, the holding elements 66 on at least jaw E54 move in an arcuate path, having the pin as as a center. This arcuate movement is not truly radial with respect to the co-operating member Eta or 2%. The oval shaping of the holes t6, however, readily permits such non radial movement and enables the jaw structures to be freely separated from the co-operating loading members. r

Referring again to Fig. 1, it will be appreciated that the fixed rails 22' are provided with inner and oute r s oi a ach ng: o n ng 6."- r Q os ratio w th heiaws 3 a ass ci d er t Qa-l members I desired addit al rows o openings 63 may be providedinthe members 22 in angularl y spaced relation to the just-mentioned openings, thereby permitting members 20 or 24 to be secured thereto in different angular positions, and in factmaking members 22 iden-.- tical with members 26 and Her at least enabling them to be formed of the same tubing, either the larger or smaller size and with the same holes; thereby givingrise to the advantages men,- tioned above connection with the interchangeability of parts 29.2 l. Moreover, it will be appreciated that it is within the purview of the invention to secure members Z2to the vehicle by readily detachable or removable fastening means, which may be, ior example, in the form of studs such as 55. In cases where members 22 are de,. tachably secured, they may be telescopically ex tensible lengths identical with members .26 or 25, without jaw Structures. Alternatively, members or as may be detachably secured to the vehicle and serve as side rails with their jaws thereon. Further, such a side rail may be formed of either an inner or an outer telescopic section, or of both such sections, of members ace-2s, detached or pulled apart. In general, the only members which are secured to members 22 are the verticaliy extending members 25. Consequently, the two inner and outer rows of openings 6i] are usually suff cient.

Also, if desired, more than four rows of openings may be provided in the elements which make up the members 29 and 29. As .a general rule, however, the indicated four rows are found to be sufficient, particularly in view of the panting relation which is permitted by the elongated character of the openings cc and by the somewhat loose fit between the surfaces of the jaw elements and the surfaces of the inner and outer te escopi all r lat d s tions- It will be evident that various combinations of vertical, horizontal, and diagonally extending members may be made up from the members such as 2!} and 2a, to accommodate different freight-loading situations. 'In pig. 1 the character of the freight is such thathorizontal bulkhead elements are best adapted to hold the freight in place. In Fig. 9, on the other hand, the character of the load is such that the bulkhead elements are better adapted to extend vertically. In Fig. is again, the character of the freight load may be such as to make it desirable to utilize a heavy net its, formed of rope or the like. IThis net may be held in place by threading the members such as 2t and 2 3 therethrough.

Again, it will be understood that, if desired, members such as 28 and $2 may be arranged so as to define decking'bins, partitions, and the like, in the manner described in said copending application. In such latter event, for example, members 2i may be arranged at intervals along the length of the chamber to define side bays, short members 20 may extend between adjacent uprights and serve as bay members, and further members as may extend across the space and be supported by such bay members. Moreover, cross members such as 2e may be connected directly between side rails 22, and between rails -2i-23 in the event the rejcessing of the latter permits or is eliminated.

Although only several embodiments of the invention have been described in detail, it will be appreciated that various modifications in the orm. numb r an ar a ge en of p rt me! be made without departing from the spirit scope of the invention. w i
