A means is provided for releasably holding the arm in its lowered position to maintain the holddown part in engagement with the object. The holddown part is connected to the arm for movement toward and away from the supported object while the arm is held in lowered position.

SHEET 2 OF 2 ATENTED SEP28197| CONTAINER HAVING INTERNAL OBJECT SUPPORT MEANS AND A PIVOTED TOP SECTION This invention relates to improvements in containers for use in shipping and storing large, heavy objects such as jet aircraft brakes or the like.

Due to their bulk, objects of this type are capable of producing considerable momentum as the container undergoes impacts during use. Therefore, unless the object is held against movement in the container, it may cause severe damage both to itself and the container. In fact, if left unchecked, the momentum might even sever one section of the container from the other, particularly along the edges where they are joined, and thus further damage the aircraft in which it is transported and/or articles such as luggage within the aircraft.

Another prerequisite for a container of this type is the ability to hold objects of varying sizes, such as brakes for different jet aircraft. Furthermore, the means by which the object is held must be capable of quick and easy release, particularly in the case of jet aircraft brakes where downtime of the aircraft is at a premium. Still further, it is especially desirable that the means by which the object is held down require no parts which need be removed from the container, and thus lost, misplaced or stolen.

An object of this invention is to provide a container which satisfies these requirements.

More particularly, it is an object of this invention to provide a container which may be used to hold down objects of varying size, from which the object may be quickly and easily removed, and in which, in normal operation, no parts need be removed from the container.

Another object is to provide such a container which is capable of being easily and quickly adjusted to the size of the object to be secured and then forced tightly against the object.

A further object is to provide such a container in which the object is held down against loadings in all directions.

Still another object is to provide such a container which is especially useful in holding down hollow objects.

These and other objects are accomplished, in accordance with the illustrated embodiment of the invention, by a container having a bottom section on which the object may be supported, a top section hingedly connected to the back side of the bottom section for swinging between raised and lowered positions, and means for latching the front side of the top section to the bottom section when in lowered position. An arm carrying a holddown part is hingedly connected to the bottom section for swinging between a lowered position in which the holddown part on the arm bears on the top of the supported object and a raised position above the object to permit it to be moved from supported position on the bottom section. A means is also provided for releasably holding the arm in its lowered position so as to maintain the holddown part in engagement with such object.

Thus, with both the top section and the arm raised, the object may be moved into supported position on the bottom section, and the arm then lowered and latched in such position. In the event the holddown part is not properly located to bear on the object, suitable adjustments may be made, as in the manner to be described. The top section may then be lowered and latched in such position to enclose the object. Conversely, in order to remove the object, it's necessary to merely raise the top section of the container from the arm and then raise the arm, and thus the holddown part, from the object.

More particularly, in the illustrated and preferred embodiment of the invention, the holddown part is connected to the arm for movement toward and away from the object. Thus, with the arm latched in its lowered position, the holddown part can be adjusted vertically to the height of the object in the container. This, of course, permits different objects to be held in the container.

It is also preferred that the top section of the container bear on the top of the arm and the sides of the arm be closely received with a slot in the inner side of the top section when both the top section and arm are lowered. In this way, the object itself structurally reinforces the container in a direction from top to bottom, and the frame cooperates with the container to reinforce it from front to back and side to side.

In the preferred form of this container, the means connecting the holddown part to the arm includes a hollow rod threadedly connected to the arm for movement toward and away from the rod, a stem threadedly connected to the rod for extension and retraction with respect to it, a means securing the holddown part to the stern, and a lock on the rod for limiting its upward movement in the arm. In this manner, when the lock is in limiting position, the holddown part may be turned to extend the stem and thus move such part easily and quickly into engagement with the top of the object to be secured. More particularly, the threads between the arm and the rod are of different pitch than those between the rod and stem, so that when such part is so engaged, the rod may be turned to back the lock off from its limiting position and force the holddown part more tightly against the top of the object.

More particularly, in the illustrated embodiment of the invention, the arm comprises part of a frame which includes a pair of uprights which are secured to and extend above the upper edges of the sidewalls of the bottom section of the container. One end of the arm is pivotaily connected to the upper end of one such upright and the other end is adapted to be supported on the upper end of the other upright, and a latch is provided for releasably connecting the arm to the other upright in its supported position thereon. In the interest of further strengthening the container, the frame includes another arm which is connected to the lower ends of the uprights and is secured to the bottom wall of the bottom section of the container.

The illustrated container is especially well suited for use in holding down hollow objects in that it includes a guide on its bottom section adapted to be received in the lower end of the opening through the object in supported position. Also, the holddown part includes a base which is enlarged to bear on the top of the object and a narrow, lower extension which moves into the upper end of such opening as the swinging arm is lowered. More particularly, the guide has an opening for alignment with the opening in the supported object, and the lower end of the lower extension of the holddown part may, in same cases, move into the guide opening to thereby further reinforce the object against lateral displacement.

FIG. 1 is a perspective view of the front, one side and the top of a closed container constructed in accordance with the present invention;

FIG. 2 is a perspective view of the container, similar to FIG. 1, but with the top section swung to open position;

FIG. 3 is a vertical sectional view of the closed container, as seen along broken line 3-3 of FIG. 1;

FIG. 4 is another vertical sectional view of the closed container, as seen along broken line 4-4 of FIG. 1;

FIG. 5 is an enlarged sectional view of the lower end of the connection of the holddown part to the arm of the frame;

FIG. 6 is an enlarged cross-sectional view of the upper end of the connection, as seen along broken line 6-6 of FIG. 4; and

FIG. 7 is a view of the holddown part connected to the swinging arm in an alternative position.

With reference now to the details of the above-described drawings, the. container shown in FIGS. 1 and 2, and designated in its entirety by reference character 10, comprises a bottom section 11 hinged at 13 to a top section 12 to permit the top section to swing between its lowered, closed position in FIG. 1 and its raised, open position in FIG. 2. In the closed position of the container, the top section is releasably connected to the bottom section by latches 14. The hinge 13 may be of a conventional piano type. The latches 14 may also be of conventional construction, such as the spring-loaded type manufactured and sold by the Simmons Fastener Corporation of Albany, N.Y., and illustrated on page 35 of that company's Catalog No. 760.

The bottom section 11 has sidewalls upstanding from the bottom wall of the bottom section, and the top section 12 has sidewalls depending from the top wall of the top section. For purposes of this description, the hinge 13 connects the top and bottom sections of the container at the rear side thereof, and the latches 14 releasably hold the sections in closed positions at the front side of the container. As shown in FIGS. 1 and 2, handles 15 and latches 14 are received within recesses on opposite sidewalls of the bottom section to facilitate carrying of the container.

As shown in FIGS. 3 and 4, the upper edges of the sidewalls of the bottom section 11 are provided with tongues 16 for engaging a recessed strip 18 of rubber or other resilient material within grooves 17 in the bottom edges of the sidewalls of the top section 12. Thus, there is no metal-to-metal contact between these edges, so as to seal the container against dust and also cushion shock loads thereon. In accordance with the present invention, a frame 19 is secured by rivets 20 or the like to the inner sides of the walls of the upper container section 12 for further reinforcing the separation between the sections of the closed container against laterally or horizontally directed loads. Thus, as shown in FIGS. 3 and 4, the lower end of the frame 19 projects downwardly from the lower edges of the sidewalls of the container section 12 to fit closely within the inner sides of the upstanding walls of the bottom section 1 1.

The object 21 to be secured within the container is shown by broken lines to comprise a brake having a hub 21a and flanges 21b and 216 on opposite ends of the hub. As well known in the art, discs 21d are received about the hub and between the flanges. Further detail is, of course, unnecessary since the container is obviously useful for shipping and storing other hollow objects; and, with some obvious modifications, nonhollow objects.

In any event, and as shown in FIGS. 3 and 4, when the bottom of the object 21 is supported upon the bottom wall of the bottom section 11 of the container, its top is spaced beneath the top wall of the top section of the container, the extent of such space depending on the height of the object.

The holddown frame, which is designated in its entirety by reference character 22, includes a pair of uprights 23 adjacent the inner sides of front and rear sidewalls, respectively, of the bottom container section 1 1. More particularly, these uprights are channels which face toward the interior of the container and are secured to the adjacent sidewall of the bottom section by rivets 230 or the like. The upper ends of the uprights extend above the upper edges of the sidewalls of the bottom section 11, as shown in FIGS. 2 to 4, and for reasons which will be apparent. The lower ends of the uprights are connected to arm or bar 24 which is secured to the bottom wall of the bottom section by rivets 25. The connection of the opposite ends of the bar to the lower ends of the uprights 23 is reinforced by plates 25a.

The frame 22 also includes an arm 26 having; one end pivotally connected at 27 to the upright mounted on the rear sidewall of the bottom section and an opposite end adapted to be supported on the upper end of the other upright mounted on the front sidewall of the bottom section of the container when the arm is lowered. When the free end of the arm 26 is so supported, it may be held down by a latch 28 having one part pivotally mounted on the front side of the upright 23 above the upper edge of the front sidewall of the bottom section of the container for cooperation with a part on the free end of the arm. This latch may be of any suitable construction, such as a type manufactured and sold by the Simmons Fastener Corporation of Albany, N.Y., and shown on page 34 of the aforementioned Catalog of that company. As best illustrated in FIG. 4, with upper ends of uprights 23 above the bottom section 11, the hinge 27 and latch 28 do not interfere with movement of the top section.

The arm 26 is an inverted U" having side members 26a and 26b at its rear and front ends, respectively, connected at their upper ends by a crossmember 26c. More particularly, the side members 26a and 26b are of such height as to dispose the top side of the crossmember 26c, and thus the top of the arm 26, for engagement by the inner side of the top wall of the top section 12 of the container when the top section is closed.

The side members 26a and 26b of the arm 26 are channels of the same size as the uprights 23 and form a vertical continuation of the uprights when the arm 26 is in the lowered position of FIG. 4. The crossmember 260 is also a channel which is inverted to face the interior of the container and reinforced by a bar along the length of the channel. The intersection of the side member 260 and the crossmember 26c is reinforced by a plate 29, and the upper end of the side member 26b tapers in a rearward direction so as to permit the front sidewall of the upper section of the container to move over the lowered arm.

A holddown part 30 is carried by and depends from the arm 26 for engaging the top of the object 21 when the arm is in its lowered position. As shown, the holddown part has a wide base 31 which is adapted to bear on the flange 21b of the object and a narrow extension 32 extending from the lower end of the base and into the hub 21a of the object. More particularly, and as will be understood from the drawings, the base comprises a hub which is enlarged at one end, and the exten sion 32 comprises a sleeve which is received through the hub. A flange 33 on the upper end of the sleeve is connected to the hub by bolts 340 which extend through aligned holes in the flange and the base 31. As shown in FIG. 7, the position of the hub on the sleeve may be reversed to lower the bearing surface on the enlarged end of the hub, as may be necessary in holding objects having less height.

The extension 32 of the holddown part 30 receives the lower end of a threaded stem 34 which connects it to the swinging arm 26 for vertical movement relative thereto. Thus, as shown in FIG. 5, the lower end of the stem is secured to the extension 32 by a bolt 35 extending through a hole in the bottom end of the extension, and the upper end of the stem is threadedly received within a hollow rod 36 for movement ver tically therein. As shown in FIGS. 3 and 4, the upper end of the hollow rod 36 is threadedly received within a hole in the crossmember 26c of the arm 26 so as to be vertically movable with respect to the arm 26 upon rotation thereof. However, this vertical movement is limited in an upward direction by a nut 37 held fast on the rod 36 by handles 38 projecting through aligned holes in the nut and the rod, as shown in FIG. 6. These handles are, of course, useful in turning the hollow rod within the threaded hole in the arm 26.

The enlarged disc or hub of the base 31 provides a part which may be gripped by the hand and turned to move the stem and thus the holddown part 30 vertically with respect to the rod 36 and thus the arm 26. More particularly, the threads between the rod 36 and arm 26 are of a larger pitch than those between the rod and the stem 34. Thus, when the arm 26 is swung to lowered position and latched to the uprights 23 of the frame, the handles 38 may be turned to move the top side of the nut 37 into engagement with the lower side of the crossmember 26c. At this time, the flange or hub of the base 31 may be gripped and rotated so as to cause the enlarged end thereof to move downwardly into engagement with the top of the object 21. The handles 38 may then again be turned so as to back the nut 37 away from the lower section of the crossmember 26c and force the holddown part 30 tightly against the top side of the object 21.

The top wall of the upper section 12 of the container is reinforced by means of inner layers 40 secured to the top wall in any suitable manner. As shown in FIG. 3, these inner layers form a slot between them to receive the crossmember of the arm 26 when both the arm and top section of the container are lowered. More particularly, a metal channel 41 is disposed about and extends lengthwise of the inner end of each inner layer 40 to protect it against wear and fit closely against the opposite sides of the crossmember. Preferably, a strip 42 of rubber or like material is disposed over the inner side of the top wall of the section 12 intermediate the inner layers so as to provide a cushion between the top section and the top of the arm 26. If desired, the top wall of the top section of the container may be further reinforced by a metal sheet 43 held between the top wall and each inner layer 40.

As shown in FIG. 3, the bottom wall of the bottom section 11 of the container is also reinforced by inner layers 44 mounted on such bottom wall on opposite sides of the bar 24 of the frame. A rubber pad 45 is disposed over the top of each inner layer 44 for cushioning the support of the bottom of the object 21. Thus, the pad 45 cooperates with the strip 42, as well as the strip 18, to absorb vertical shock loads. As in the case of the inner layers 40, a metal sheet 46 or the like may be disposed between the inner layers 44 and the bottom wall of the bottom section 11. If desired, the inner side of the bottom wall may be dished-out to aid in maintaining the object against lateral movement.

As shown in FIGS. 2, 3 and 4, a circular block 47 is bolted at 48 to the bottom wall of the bottom section of the container for fitting within the lower end of the opening through the object and thus guiding the object into supported position. More particularly, the guide 47 has a central hole or opening 49 which, in some cases, depending on the height and size of the opening through the object 21, may receive the lower end of extension 32 of the holddown part 30 as the arm 26 is swung to its lowered position and through the keyhole 49a in the hole. This, of course, is a further deterrent to substantial lateral movement of the object.

As will be understood from the foregoing, removal of the object 21 from the container merely requires that the top section be released from the bottom section of the container, and swung to the raised position shown in FIG. 2, the nut 37 be turned to relieve pressure on the part 31, and the arm be released from the front upright of the frame 22 and swung to raised position, as also shown in FIG. 2. Also, since the frame extends perpendicularly to the hinge 13 between the sections of the container, the arm 26 of the frame will swing up and into the top section of the box, when both of them are raised, thereby consuming a minimum of space as well as providing a convenient stop for locating the arm in raised position.

When the container is again to be used to contain an object, the handles 38 are turned to raise the nut to limiting position and the holddown part 30 is raised by manipulation of the hub. The object is then moved into supported position on the bottom section of the container, and the arm 26 swung downwardly and latched. The hub is then again manipulated to lower its lower side into engagement with the object, after which the handles 38 are turned to force the hub tightly against the top of the object. At this time, the top section of the container may be swung down and latched in position.

Since the frame 22 extends transversely to the hinge 13 between the top and bottom sections of the container, it reinforces the container against loading in a direction from front to back. Also, the crossmember 26c of the arm 26 is received in a slot in the top section of the container, the frame reinforces the container in a direction from side to side. On the other hand, since the top section of the container bears on the top of the arm, and this force is in turn transmitted through the rod 36 and stem 34 to the holddown part 30, and through the holddown part to the object 21 and to the bottom section of the container on which the object is supported, there is considerable reinforcement against loading in a vertical direction, or from top to bottom.

From the foregoing it will be seen that this invention is one well adapted to attain all of the ends and objects hereinabove set forth, together with other advantages which are obvious and which are inherent to the apparatus.

It will be understood that certain features and subcombinations are of utility and may be employed with reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
