  • PATENTEU SEP 7 I971 SHEET 2 UF 5 CONTAINER SUPPORT AND SECUREMENT STRUCTURE HAVING COLLAPSIBLE PEDESTALS BACKGROUND OF THE INVENTION Factors such as the costs of loading and unloading merchandisc and the transfer of freight between ships, trains and trucks, as well as pilferage of freight shipped in boxcars in less than carload lots have given rise to favor for shipments in boxtype containers which can be individually sealed and also loaded and unloaded, as units of sizes commensurate with the quantity of goods shipped.
  • the vehicle In addition to being well suited to the transportation of boxtype containers, it is also desirable that the vehicle should be usable for hauling other types of loads, such, for example, as truck trailers, without material change of the car structure or substantial interference from the container supporting and securement equipment.
  • the pedestals in addition to having support and locating surfaces for the corners of containers, also have thereon latch pawls which grip and retain the containers in position on the pedestals during shipment, as, for example, to prevent dislodgment of the containers from the pedestals and vehicle as a result of side thrust forces which may be encountered in traveling around curves or comers at relatively high speeds.
  • the pedestals and guide tracks of a container support and securement system of the type disclosed herein should be correlated, constructed and arranged to embody certain features or principles. That is, after initial installation, the pedestals should not be readily removable from the guide tracks, so that they can be separated from the vehicle and lost.
  • the openings in which the pedestals are stored in a collapsed position when not in use are preferably confined to the guide tracks and should be relatively small to provide for the safety of workers.
  • the guide track slots through which the pedestals move longitudinally of the track should be relatively narrow for reasons of the worker safety and so as not to interfere materially with other uses of the vehicle.
  • the pedestals should be readily movable between their collapsed and erect positions and also between positions spaced longitudinally of the vehicle or guide tracks.
  • the pedestals should be movable along, and supported from a continuous, uninterrupted and rugged portion of the guide track structure. It is also desirable that the anchorage of the pedestals in the guide track and the structure and operation of the container latch mechanism shall be such that while the containers are firmly retained on the pedestals for shipment, their engagement and release is automatically efiected, without separate manual operations, by the force exerted as a result of container weight during loading and as a result of the lifting force of unloading equipment, such as a crane.

PATENTEU SEP 7 I971 SHEET 2 UF 5 CONTAINER SUPPORT AND SECUREMENT STRUCTURE HAVING COLLAPSIBLE PEDESTALS BACKGROUND OF THE INVENTION Factors such as the costs of loading and unloading merchandisc and the transfer of freight between ships, trains and trucks, as well as pilferage of freight shipped in boxcars in less than carload lots have given rise to favor for shipments in boxtype containers which can be individually sealed and also loaded and unloaded, as units of sizes commensurate with the quantity of goods shipped.
In addition to being well suited to the transportation of boxtype containers, it is also desirable that the vehicle should be usable for hauling other types of loads, such, for example, as truck trailers, without material change of the car structure or substantial interference from the container supporting and securement equipment.
Both the adaptation of the vehicle for use for purposes other than the hauling of box-type containers and to facilitate loading and unloading of the containers relative to the vehicle, as by overhead cranes, make it desirable that the containers shall be supported above the vehicle deck during shipment. Additionally, the accommodation of box-type containers of varied sizes and the use of corner support pedestals for the containers make it desirable that the pedestals may be used in various combinations and that at least some of the pedestals shall be movable to different positions along the vehicle. Furthermore, when not in use or prepared for use, the pedestals are collapsible to out-of-the-way positions and provide covers for openings into which they collapse into practically flush relationships to the vehicle deck.
The pedestals, in addition to having support and locating surfaces for the corners of containers, also have thereon latch pawls which grip and retain the containers in position on the pedestals during shipment, as, for example, to prevent dislodgment of the containers from the pedestals and vehicle as a result of side thrust forces which may be encountered in traveling around curves or comers at relatively high speeds.
In somewhat more specific respects, the pedestals and guide tracks of a container support and securement system of the type disclosed herein should be correlated, constructed and arranged to embody certain features or principles. That is, after initial installation, the pedestals should not be readily removable from the guide tracks, so that they can be separated from the vehicle and lost. The openings in which the pedestals are stored in a collapsed position when not in use are preferably confined to the guide tracks and should be relatively small to provide for the safety of workers. The guide track slots through which the pedestals move longitudinally of the track should be relatively narrow for reasons of the worker safety and so as not to interfere materially with other uses of the vehicle. The pedestals should be readily movable between their collapsed and erect positions and also between positions spaced longitudinally of the vehicle or guide tracks. The pedestals should be movable along, and supported from a continuous, uninterrupted and rugged portion of the guide track structure. It is also desirable that the anchorage of the pedestals in the guide track and the structure and operation of the container latch mechanism shall be such that while the containers are firmly retained on the pedestals for shipment, their engagement and release is automatically efiected, without separate manual operations, by the force exerted as a result of container weight during loading and as a result of the lifting force of unloading equipment, such as a crane.
THE PRIOR ART ln the past, other structures and structural combinations have been devised for comparable and related purposes, and have been patented. Some such prior devices have incorporated parts requiring large amounts of material and expensive machining operations which have made them too expensive to manufacture and install to be economically feasible.
Others have required relatively large openings in the vehicle deck for storage and even segmentation of the guide tracks for accommodation of the pedestals in collapsed storage positions. Some, because of bulk, storage problems and complication have not been suited to use on multipurpose vehicles.
SUMMARY OF THE INVENTION In view of factors which include the foregoing considerations, it is a general object of this invention to provide a support and securement structure for the transportation of containerized lading on a carrier vehicle, which structure em'- bodies guide tracks made from relatively standard roller steel sections and has unitary pedestals for supporting the lading containers above the vehicle deck and which are both movable through a relatively narrow top guide track slot to predetermined positions of use and collapsible to out-of-theway positions through relatively small cutout portions in the tops of the guide tracks and into generally flush relationship with the vehicle deck when not in use.
As another object, this invention has within its purview the provision of a support and securement structure of the type discussed and which, together with a guide track having upper and lower flange portions connected by a web, has container supporting pedestals movable to and adapted to" be held in predetermined positions along the guide track and which each include an integral base element mounted between the uppei' and lower flanges of the guide track for support by and from the lower tack flanges, for movement longitudinally of the track, and for swinging movement between upright and collapsed positions relative to the track.
This invention further comprehends the provision of a unitary pedestal having an integral base element supported and retained within a guide track for movement therealong and relative to which the pedestal is swingable from an upright load supporting position to a collapsed position practically flush with the track and in which portions thereof extend through the track between opposite sides thereof.
It is another object of the invention to provide, in combination with a guide track composed of bulb angle sidepieces secured in opposed relationship with upper and lower flanges of the sidepieces extending toward one another and spaced to define upper and lower slots of different widths therebetween, a lading container comer support pedestal having a backplate element of a width greater than that of the upper slot and nai rower than the guide track and extending laterally of the track with means at the lower end thereof for engagement in notches in the upper flanges for holding the pedestal in a fixed position relative to the track, container support i'neans at the upper portion of the backplate element and of a' width less than that of the lower slot, an integral supporting base movably mounted between the sidepieces and between the flanges thereof and supported at its opposite sides from the lower flanges, an integral brace structure extending from the backplate element below the containef 'siipport means and above the base, said brace structure being narrower than the upper slot and movable therein and also narrower than the lower slot and movable therethrough, said pedestal being tiltable in one direction longitudinally of the guide track and having means thereon for preventing tilting in the opposite direction and additional means for releasably retaining the pedestal in an upright position on the track.
Another object of this invention is to provide a guide track for a container corner support pedestal which hasopposite marginal portions which serve also as supports for vehicle deck plates in spaced relationship on opposite sides thereof and which has an opening therein into which the pedestal is collapsible and wherein the container support pedestalsare narrower than the space between the deck plates; so that the pedestal, when collapsed, rests against the guide track between the deck plates in generally flush relationship to the latter.
This invention also has within its purview the provision of a unitary container corner support pedestal for the use on transport vehicles which has at the lower end thereof a base ele ment from which it is supported through opposed and oppositely projecting end segments of a sectional shape and size such that they can roll on a supporting surface within a limited space, a backplate element extending upwardly above the base element and having container corner seat and retaining parts thereon and carried thereby above the base element, a brace structure connecting the base and backplate elements and extending beneath the container corner seat, and means on the backplate element and also on the brace structure for stabilizing the pedestal in an upright position relative to a supporting structure.
It is also within the comprehension of this invention to provide a container corner support pedestal of the type to which reference has been made and which has thereon a container securernent latch mechanism operable by placement of the container on the pedestal for effecting retaining engagement of the latch with the container, and operable by lifting force applied to the container, as by a crane, for effecting release of the latch from retaining engagement with the container during the unloading of the container.

DESCRIPTION OF THE PREFERRED EMBODIMENT Having reference to the drawings, and particularly to FIGS. 1 and 2, the disclosed container support and securernent structure is shown in an adaptation to use on a railway flatcar 20. As is practical for general service in such an adaptation, the flatcar 20 which is illustrated as one which is suited to a plurality of purposes, including the hauling of vehicle trailers, as well as for hauling lading which is carried in containers of relatively standardized sizes which are loaded and unloaded by cranes or the like, and do not have wheels thereon, as do the vehicle trailers. For hauling trailer vehicles, the car is equipped with stanchions 22 and 23 which, when erect, as the stanchion 22 is shown, support the front end of the trailer vehicle. When not in use, the stanchions fold to an out-of-theway position in generally flush relationship to the car deck 24, as shown at 23. Generally, guide rails, such as 25, are provided in spaced relationship along the midregion of the car deck 24 as an aid for loading and unloading the trailer vehicles and to insure their proper positioning laterally of the car. At the ends of such a car, plates 26 and 27 are provided, which plates fold down to bridge the space between coupled cars, so that trailer vehicles can be moved from car to car for loading and unloading purposes.
The underframe of the disclosed car is of a relatively standard form utilized in a car construction and includes a center sill 28 and side sills 29 and 30 which extend longitudinally of the car. At spaced positions along the car, crossmembers 32 and 33 are provided, and are braced relative to the center sill 28 by braces 34 and 35. These crossmembers extend between the side sills 29 and 30, and carry longitudinal stringers 36 and 37 which are spaced on opposite sides of the center sill 28 and which are also spaced inwardly from the side sills 29 and 30 and serve as supports for the deck 24 which, in the present instance, comprises a metal plate 38 covering the lateral midregion of the underframe throughout the length of the car.
For the adaptation of the car to the hauling of containerized freight, in accordance with this invention, guideways 39 and 40 are provided at opposite sides of the car deck for accommodation and support of pedestals, such as 42 and 43, which pedestals are adapted to the support of lading containers above the car deck in positions such that the containers clear the guide rails 25 and folded stanchions such as 23, and in which supported positions, the containers can be readily grasped at their opposite sides for loading and unloading relative to the car.
In the form illustrated, each of the sections of the guideways or tracks 39 and 40 is made up of bulb angles 44 and 45 which are secured, as by welding, to the tops of the crossmembers 32 and 33 to extend longitudinally of the car adjacent and spaced inwardly of the side sills 29 and 30; the bulbs angles being oppositely disposed with lower flanges 46 and 47 and upper flanges 48 and 49 extending toward one another and spacedapart to respectively define lower slots 50 and upper slots 52. The flanges 46 and 48 are integrally adjoined by a web 53 and the flanges 47 and 49 are integrally adjoined by a web 54. As shown, the height of the bulb angles 44 and 45 is comparable to that of the longitudinal stringers 36 and 37, so that the margins of the bulb angles serve as supports for the deck 24. As shown in FIG. 2, deck plate strips 55 and 56 extend longitudinally of opposite sides of the car and bridge the space between the side sills 29 and 30 and the outer margins of the top of the bulb angles 44 and 45.
Having reference to FIGS. 3, 4 and 5, the guideways 39 and 40 which extend along opposite sides of the car deck are divided into end segments 39a, 39b, 40a and 40b which are located near opposite ends of the car deck and relatively long intermediate segments 39c and 40c which extend along portions of the longitudinal midregion of opposite sides of the car deck. Each of the end segments 39a 39b, 40a and 40b is adapted to the accommodation of a single pedestal at a fixed erect position or a collapsed position, while the long intermediate segments of the guideways 39c and 400 each accommodate a plurality of pedestals in either erect positions for supporting containers or in collapsed positions, and which pedestals are movable along the guideway segments for releasable retention in erect container supporting positions, as well as being collapsible at selected positions along the guideway segments. In the intermediate guideway segments, the pedestals are mounted to face in different directions, while the pedestals in the end segments 39a, 39b, 40a and 40b face inwardly of the car, in each instance, whereby the pedestals in the intermediate segments are selectable for use with one another or with the pedestals in the end segments for the accommodation of different numbers of containers of different sizes at different times.
Although reversed at the opposite ends of the car, the end segments 39a, 39b, 40a and 40b of the guideways are constructed substantially as illustrated at the right-hand side of FIG. 4 in respect to the segment 40b. As depicted, the bulb angles are supported from the underframe, as illustrated and described with regard to FIG. 2, and the deck 24 extends along opposite margins of the upper flanges 48 and 49, except at the end of the car, where the deck plate covers an unused portion of the bulb angles. The top flanges 48 and 49 of the bulb angles have opposed notches 57 and 58 therein, which notches serve to releasably retain a pedestal in its upright position as will be described. At a position spaced from the edges 57 and 58 the upper flanges 48 and 49 are cut away toward the webs 53 and 54 to provide an opening 59, into which a pedestal may be collapsed. At the end of the bulb angles opposite the'notches 57 and 58 and adjacent the opening 59, the upper flanges 48 and 49 and the webs 53 and 54 are cut away to the depth of the upper flanges 48 and 49 to provide an opening 60for the installation of a pedestal in the guideway segment, after which the opening 60 is covered by cover plate 62 which is welded to the respective bulb angle webs and forms a surface substantially flush with the deck to prevent n removal of a pedestal from the guideway segment after it has been installed. From the foregoing, it may be understood that each of the end guideways segments 39a, 39b, 40a and 40b comprises a relatively short track segment which accom modates a single pedestal and provides for the support of that pedestal in a relatively fixed erect position, as well as for the collapse of the pedestal into and through the track segment itself to a position in which it has generally flush relationship to the car deck.
As shown in FIGS. 3, 4 and 5, the intermediate guideway segments 39c and 40c are longer than the end segments and accommodate a plurality of pedestals, with provision for the releasable retention of those pedestals in a plurality of fixed positions spaced longitudinally of the guideways, as well as providing for the collapse of the pedestals at positions spaced longitudinally of the intermediate guideways. The notches 63 and 64 are provided in opposed relationship at regularly spaced positions along the upper flanges 48 and 49 of the intermediate guideway segments. At positions spaced from one another and intermediate the notches 63 and 64 of the intermediate guideway sections, portions of the upper flanges 48 and 49 are cut away to provide openings 65 between lateral limits of the guideways into which pedestals may be collapsed. The spacing of the opening 65 and the number of such openings depends upon the number of pedestals which are provided on a car to accommodate various sizes of containers for transportation thereby, while the spacing of the notches is also suited to the number of sizes of the containers which are to be accommodated on the car. At the opposite ends of the intermediate guideway sections, the upper flanges 48 and 49 are completely cut away, and the webs 53 and 54 are cut to the depth of the upper flanges to provide openings 67 for the installation of pedestals. After the pedestals are installed, cover plates 66 are secured to the bulb angles of the guideways to cover the openings 67, thereby preventing removal and loss of the pedestals in service. In opposite longitudinal halves of the guideway segments 39c and 400 pedestals are disposed to face in opposite directions, with their number and dispositions selected to provide for the support and transportation of different numbers and different sizes of containers. For example, in the structure disclosed, provision is made for the support and transportation of two containers which take up practically the entire length of the car deck, or three containers supported in closely spaced relationship, or four shorter containers which are in spaced relationship longitudinally of the car deck. In each instance, the pedestals in the end guideway segments 39a, 39b, 40a and 40b are utilized with selected ones of the pedestals in the intermediate guideway segments 39c and 40c c. Also, when three or four containers are carried on the car, the intermediate guideway segments and the pedestals thereof support one or more containers, in addition to the ends of the containers which are additionally supported from the end guideway segments.
Having reference to FIGS. 6, 7, 8 and 9, the pedestals preferred for use in the disclosed structure are unitary with the parts thereof constructed andarranged for support from a continuous and rugged portion of the guideway segments, and in addition to being movable longitudinally of the guideways through relatively narrow slots to selectable positions of support in erect positions, are also collapsible into relatively small openings in the guideway structure, so as to be in generally flush relationship to the car deck and to cover the opening into which they are collapsed. Although the pedestals for use on opposite sides of the car have parts which are oppositely disposed to provide corner seats for containers which open inwardly of the car deck, the pedestal structures are generally alike so that a detailed description of one will suffice for those utilized on both sides of the car. Actually, in most respects, the pedestal structures are symmetrical on opposite sides of a central plane extending longitudinally of the car, but in each instance, the selection of the position of the sidewall of the container seat determines the side of the car upon which the pedestal is to be mounted to have the comer seat open inwardly of the car deck.
Each pedestal has a backplate element 68 which is upright in the erect position of the pedestal, and it serves to cover one of the openings 59 or 65 in the guideway segment when the pedestal is collapsed relative to the guideway. The backplate element 68, in the structure disclosed, is narrower than the space between the deck plate 38 and the deck plate strip 55 secured to opposite sides of the . upper guideway flanges 48 and 49, so that in the collapsed position of the pedestal, the backplate element rests against the upper flanges 48 and 49 of the guideway between the deck plate 38 and deck plate strip 55. Also, the backplate element 68 is wider than the outward extent of the opposed notches 57, 58, 63 and 64, so that when collapsed, the pedestal has substantial support from the upper guideway flanges. At its lower end, the backplate element has thereon an integral projecting tongue 69 which is narrower than the backplate element and of a width to extend downwardly through the opposed notches in the guideway when the pedestal is in an erect position, as shown in FIGS. 7 and 8. Integral with the tongue 69 is a flange 70 spaced from the end of the backplate element and extending rearwardly therefrom for engagement with the lower surfaces of the upper flanges 48 and 49 to stabilize the pedestal in its erect position. The tongue 69 and its integral flange 70 are limited in size to pass through the notches in the guideway flanges, after which, engagement of the flange 70 with the lower surfaces of the upper guideway flanges is effected by limited rearward movement of the pedestal relative to the guideway.
A container seat 72 is, in the form disclosed, integral with the forward surface of the midregion of the backplate element 68 and extends forwardly therefrom so that when the pedestal is in its upright position of use, as shown in FIGS. 6 and 7, the seat is disposed in a generally horizontal plane. At one side of the container seat 72, a side retaining wall 73 extends upwardly from the container seat to a level substantially even with the top of the backplate element, and is secured, as by welding, to both the container seat and the backplate element. The side of the container seat on which the side retaining wall 13 is mounted determines the side of the car on which the pedestal is usable or the direction of forward disposition of the pedestal relative to the car for use. Extending forwardly from the lower lateral midregion of the backplate element and across the lower surface of the container seat 72 is an integral brace structure 74, which brace structure is of a width or thickness such that it extends through the upper slot 52 of the guideway and is readily movable therein.
A crossmember 75 is integral with the forward end of the lower surfaces of the brace structure 74 and extends laterally in opposite directions from the brace structure to engage the lower surfaces of the upper flanges 48 and 49 of the guideway, thereby to prevent rearward tilting movement of the pedestal from its erect position.
Below the brace structure 74, at a position forward of the backplate element 68 and spaced rearwardly from the crossmember 75 and integral with the brace structure in a base 76 which extends laterally of the pedestal with oppositely projecting and opposed end portions 77 and 78 in supporting and sliding engagement with the upper surfaces of the lower flanges 46 and 47 of the bulb angles. Being thus disposed, the base 76 extends movably between the webs 53 and 54 of the bulb angles with the end portions thereof disposed between the upper and lower flanges of the bulb angles. In addition, the base has a sectionally enlarged midregion 79 providing shoulders 80 and 82 adjacent the projecting end portions 77 and 78 respectively which shoulders normally extend between the inner edges of the lower flanges 46 and 47 to position the base and pedestal laterally of the guideways. Also, in the disclosed structure, the end portions 77 and 78 of the base have front surfaces 83 and 84 and bottom surfaces 85 and 86 which respectively taper rearwardly and upwardly toward their outer ends for surface engagement with the sloping inner surfaces of the lower flanges 46 and 47. The base has a height such that when the opposite end portions 77 and 78 thereof are engaged with the lower flanges 46 and 47, the top surface of the base closely approaches the lower surfaces of the upper flanges 48 and 49 to limit lateral rocking movement of the pedestal in the guideway; there being some space provided between the top of the base and the lower surfaces of the upper flanges 48 and 49 to provide for forward and rearward tilting movement of the pedestal relative to the guideway to and from the erect position and positions shown in FIGS. and 12. Additionally, the front and bottom surfaces of the end portions 77 and 78 of the base are adjoined by rounded surfaces 87 and 88 which permit rolling movements of the pedestal relative to the guideway between the erect and collapsed positions shown in FIGS. 7 and 10 respectively. In the disclosed structure, an integral brace 89 extends upwardly and rearwardly from the lateral midregion of the base to the rear end of the brace structure 74.
Although gravitational forces tend to hold the corners of lading containers in place on the container seats of properly located pedestals in their erect positions, safety factors make it desirable to provide latch elements on the pedestals which engage base elements, such as 90, (FIGS. 13, I4 and at the bottom of a container to secure the containers in place against dislodgement by forces such as those encountered in going around corners at high speed or when cars are coupled. In the disclosed structure, a spring-urged latch mechanism 92 is utilized, which latch mechanism is automatically actuated to effect engagement with the container base element 90 when a container is lowered onto its supporting pedestal, and which is subject to automatic operation for removal of a container from the pedestals by a crane or the like, although its retaining engagement is otherwise normally sufficient.
As herein shown, the brace structure 74 has outwardly projecting bosses 93 and 94 on opposite sides thereof and immediately below the container seat 72. Counter bores 95 and 96 are provided in opposite sides of the bosses 93 and 94, which counter bores serve as seats for resilient elements, such as a compression spring. Since only one latch mechanism is required on each pedestal and is disposed on the side of the pedestal on which the side retaining wall 73 is mounted, only one of the counter bores is utilized on each pedestal, although the other parts of the pedestals are suited for having the side retaining wall and the latch mechanism mounted at either side thereof.
The side retaining wall has an opening 98 therein at a position spaced forwardly of the backplate element 68. A latch element 99 is hingedly mounted for swinging movement between lugs 100 on the bottom of the container seat by a cross pin 102. Above the cross pin 102, the latch element has an arm 103 on which there is a projecting latch portion 104 which is movable freely through the opening 98 in the side retaining wall 73 between a normal latching position, depicted in FIGS. 13 and 15, and a displaced or retracted position, shown in FIG. 14. The latch element 99 also has a lever portion 105 extending downwardly from the cross pin 102 and which has a boss 106 thereon which serves as a locator for the other end of the compression spring 97, whereby the latch element is biased toward its engaged or retaining position, shown in FIGS. 13 and 15.
The latch portion 104 normally projects through the side retaining wall 73 at a position spaced above the container seat 72. For effecting automatic operation of the latch, an upper cam surface 107 is provided on the latch portion 104, which cam surface is angularly disposed to be engaged by the base element of a container when it is lowered toward a seating position on a pedestal, as shown in FIG. 13, whereupon the weight of the container acting against the cam surface 107 biases the latch element 104 outwardly from above the container seat, as shown in FIG. 14, to permit the container to be lowered into position on the container seat. When the base element 90 of the container is seated against the container seat 72, the latch element is biased by the compressed spring 99 to the position shown in FIG. 15, in which the projecting portion 104 of the latch element is engaged in an opening 108 in the seat of the base element. When thus engaged, the latch element restrains movements of the container against forces normally encountered in use.
When the container is lifted by a crane, or the like, to effect the removal thereof from the pedestals on which it is seated, the lower surface of the opening 108 in the base element 90 of the container engages a lower earn surface 109 on the latch element which as a steeper cam angle than the cam surface 107, so that it has greater retaining force for resisting dislodgment of the retaining latch. However, it is effective for producing disengagement of the latch element from the opening 108 when sufficient lifting force is exerted for unloading the container.
From the details of the structure which have been described, it may be understood that the unitary pedestals herein disclosed are readily movable along the rugged and continuous lower flange surfaces of a guideway through a top guideway slot which is relatively narrow and which does not interfere with the use of the deck surface of the car for other purposes. When folded to an out-ofthe-way position, as shown in FIGS. 10, 11 and 16, the retracted parts of the pedestal extend through openings in the guideway which are only of sufficient length to receive the container seat 72, the
laterally projecting bosses 93 and 94 on the bottom of the container seat, the side retaining wall 73 and the latch mechanism 92. The crossmember 75 on the brace structure 74 has a lateral length, such that it passes between the lower flanges 46 and 47 of the bulb angles, whereby the openings in the guideways are relatively small when the pedestals are in their erect positions, and are covered by the backplate element 68 when the pedestals are retracted. The pedestal base 76 extends into the bulb angles of the guideway to restrain lateral movements of the pedestal, and yet the longitudinal dimensions of the base permit rolling movement of the pedestal relative to the base in the guideway for movement of the pedestal to a position such as that shown in FIG. 12 in which it is slidable along the guideways, or to the collapsed position shown in FIGS. 10, 11 and 16. The position of the base longitudinally of the pedestal and the retaining flanges 70 which engages the lower surfaces of the upper flanges 48 and 49 of the guideways provides stability of the pedestals in an erect position. Furthermore, the crossmember 75 insures against rearward tilting movement of the pedestals relative to the guideways.
Except for the side retaining wall 73 and the latch mechanism 92 which is utilized therewith, the parts of the unitary pedestal are laterally symmetrical with respect to a longitudinal central-plane and are subject to integral manufacture by conventional methods and require a minimum of machining operations. Then, the side retaining walls and latch mechanisms can be applied to either side of the container seat to adapt the pedestal structure to use on either side of a vehicle, or to mounting to face either end of the car for utilization in carrying different numbers of containers in different positions on the car.
