This disclosure relates generally to packaging of door assemblies.
A door assembly can include a frame and one or more doors. Generally, the door assembly may be manufactured such that the frame is constructed as a separate component from the one or more doors. This allows for convenient installation on site upon delivery, as the frame can be installed easily at the desired location with the one or more doors being subsequently fittingly supported to the frame to complete the door assembly on site.
Where the frame and one or more doors are manufactured as separate components, the frame and one or more doors are also generally packaged for shipment as distinct parts. Namely, an appropriate number of frames are packaged together in a first, usually large, box while an appropriate number of doors are packaged together in a second box. The first and second boxes are loaded onto a trailer for shipment, and this process is repeated until available trailer space has been filled. Where the door assemblies are of a type that includes more than one door per frame (e.g., a left door and a right door), the second box will generally be made to contain an appropriate number of left doors and an additional third box will be used to contain an appropriate number of right doors.
The described packaging and shipment of door assemblies as distinct components in separate boxes can result in an inefficient use of available trailer space. This is particularly the case for door assemblies that include more than one door per frame. In such door assemblies, in addition to the increased trailer space occupied by the additional door boxes, the frames are of an increased size (e.g., cross-sectional area) in order to receive multiple doors. Consequently, a larger box must be used for packing such frames. This results in an increased footprint of the frame box within the trailer, and thus less available trailer space for additional boxes needed for the added doors. Yet, the content of the larger frame box is mostly air.
In general, this disclosure is directed to improved packaging of door assemblies. The described door packaging assembly embodiments make optimal use of available space so as to allow for a significantly increased number of door assemblies to be shipped without increasing the space needed.
In one example, a door container component is positioned on a pallet and doors are configured within the door container component. The configuration of the doors within the door container component can be such as to optimally use available space within the door container component but at the same time prevent damage to the doors. The door container component can be dimensioned according to an interior area defined by a frame of the specific door assembly. The frame can be positioned around the door container component. Additional frames can also be positioned around the door container component and on top of the initially positioned frame, such that the frames encompass at least a portion of an external surface of the door container component (e.g., a surface of the door container component opposite a surface interfacing with the doors). A frame sleeve can be arranged around the frames for protection.
The details of one or more examples are set forth in the accompanying drawings and the description below. Other features, objects, and advantages will be apparent from the description and drawings, and from the claims.
The following drawings are illustrative of particular embodiments of the present invention and therefore do not limit the scope of the invention. The drawings are not necessarily to scale (unless so stated) and are intended for use in conjunction with the explanations in the following detailed description. Embodiments of the invention will hereinafter be described in conjunction with the appended drawings, wherein like numerals denote like elements.
The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary embodiments of the present invention. Examples of constructions, materials, and dimensions are provided for selected elements, and all other elements employ that which is known to those of ordinary skill in the field of the invention. Those skilled in the art will recognize that many of the noted examples have a variety of suitable alternatives.
In general, the described door packaging assembly embodiments allow for an optimized number of door assemblies to be loaded and shipped. The door packaging assemblies use space already occupied by the frames to securely accommodate the doors. In addition, various features may be included so as to protect and secure both the doors and frames, for instance, during loading, transit, and unloading. As a result, the described door packaging assemblies can facilitate the shipping of a significantly greater number of door assemblies in a same space as that used in previous door packaging arrangements.
The frame 22, right door 24, and left door 26 may be manufactured as distinct components. The frame 22 can include a front side 28 and a back side 30, with a width of the frame 22 extending between the front side 28 and the back side 30. Each door 24, 26 may include a handle 32 along a front side 34 of the doors 24, 26. Both the frame 22 and doors 24, 26 may be dimensioned such that the frame 22 fittingly supports both doors 24, 26 within the frame 22 upon assembly (e.g., on site). For instance, in one embodiment the doors 24, 26 may be pivotally coupled to the frame 22, while in another embodiment the doors 24, 26 may be slidingly coupled to the frame 22.
With the exemplary door assembly 20 having now been described, the remainder of the present description will detail optimal packaging of the door assembly 20.
As shown in
Bottom door holder 54 can be dimensioned to fit within the first sash box portion 52 of the door container component 50. The bottom door holder 54 may include a separator 58 and one or more positioning strips 60. In the embodiment shown, bottom door holder 54 has the separator 58 extending substantially along a width of the holder 54 at the center of the holder 54. As seen in
As shown in the example of
In other embodiments, the doors 24, 26 can be configured in a manner, in addition to or as an alternative to the staggered configuration, that takes into account the handles 32 on the front side 34 of each door 24, 26 (see
To further protect the doors loaded into the door container component 50, protective material can be disposed between each door, or between each pair of doors, on a same side of the separator 58. Such protective material can include, in some examples, cork board or other similar material.
When the doors 24, 26 have been loaded, additional components can be added to the door container component 50 as shown in
In addition, the second sash box portion 55 can be added to form at least the fourth side of the door container component 50. In some embodiments, the second sash box portion 55 can include additional surfaces that overlap with one or more of the three sides, top and/or bottom, of the first sash box portion 52 to provide additional support. In the illustrated example, the second sash box portion 55 is added after the one or more bandings 62 have been secured. One or more bandings 64 can be secured around the door container component 50, such as in one or more planes substantially perpendicular to both the pallet and the plane of the one or more bandings 62. In some instances, the one or more bandings 64 can be configured to pass through an aperture created in the tray 44 and through the pallet (e.g., under a top surface of the pallet and above a bottom surface of the pallet). Bandings 64 arranged in this manner can secure the door container component 50 to both the tray 44 and pallet. As can be seen in
As shown in
Corner protectors 80 can further be added either before or after the initial stack 70 is added to the arrangement 40 of the pallet 42 and tray 44 and door container component 50. In some instances, it may be convenient to include the corner protectors 80 after the initial stack 70 has been added, so as to allow the initial stack 70 to provide an interference fit between the stack 70 and the door container component 50 for holding the corner protectors 80 in place. The corner protectors 80 can help to protect the doors inside the door container component 50 from contact with the frames 22.
As seen in
Corner protectors 80 may be sized so as to be as tall as the cumulative stacks of frames 22 used in the arrangement. As shown, the stacks of frames, as well as the corner protectors 80, may extend above the top of the door container component 50. The interference fit between the corner protectors 80 and the stacks of frames at or near the bottom of the arrangement can provide counterforces to the corner protectors 80 helpful in supporting the portions of the corner protectors 80 extending above the top of the door container component 50. Therefore, in addition to providing protection for the doors inside of the door container component 50, the corner protectors 80 can further act to secure frames 22 extending above the top of the door container component 50.
As shown in
The door packaging assembly 100 can include vertical and horizontal corner protectors 102 and 104, respectively, as well as vertical and horizontal banding 106 and 108, respectively, secured around the frame sleeve 92 (including the top lid 110). As shown in the cross-sectional view of
Significantly, in door packaging assembly 100 multiple door assemblies (e.g., doors 24, 26 and frames 22) are thus packaged onto a single pallet 42 that has the same footprint as a pallet that otherwise would ordinarily only include the frames 22. Consequently, the number of door assemblies that can be loaded onto a trailer for shipment can be significantly increased.
Various other door packaging assemblies can be used in a configuration similar to that described here, with variations to accommodate the dimensions of the particular door assembly. In particular, the door packing assembly can be varied based on the size of the frame of the specific door assembly, such that the arrangement of the doors is configured so as to fit within the specific frame.
Door packaging assembly 200 can have a similar configuration as that previously described for door packaging assembly 100. However, the door assembly packaged in door packaging assembly 200 has differently dimensioned frames and doors. Consequently, to allow the doors 202, 204 to be securely positioned within the stacks 206 of frames 208 similar to that shown and described for assembly 100, the configuration of the doors 202, 204 within door container component 210 is altered.
Door packaging assembly 200 includes a spacer 212 positioned between each stack of doors 202, 204. The spacer 212 in the example show is made of cardboard, but in other examples the spacer 212 can be made of any other material suitable for keeping the doors 202, 204 securely positioned. The spacer 212 of the present embodiment is positioned at or near the middle of each stack of doors 202, 204 and serves to occupy what would otherwise be a void inside of the door container component 210 due to the specific dimensions of the frames 208 and doors 202, 204 in this example. Such a void may be present in the packaging of door assemblies where the frames are closer to a square shape than a rectangular shape. Packaging additional doors 202, 204 to occupy the void could require additional frames 208 to be stacked in the door packaging assembly 200 so as to keep the components of each individual door assembly within the same door packaging assembly 200. This may result in a height of the assembly 200 that prohibits loading onto a trailer. Door assembly 200 can otherwise have some or all of the same features as those described with respect to door assembly 100, and the described altered configuration of the doors 202, 204 still provides for twenty five door assemblies to be included within each assembly 200.
Door packaging assembly 300 can have a similar configuration as that previously described for door packaging assembly 100. However, the door assembly packaged in door packaging assembly 300 again has differently dimensioned frames and doors. Consequently, to still provide for an increased number of door assemblies able to be loaded onto a trailer (e.g., twenty-five door assemblies per packaging assembly), in the exemplary door packaging assembly 300 the configuration of the doors 302, 304 (within door container component 310) within the stacks 306 of frames 308 is altered.
The specific frame 308 of the door assembly packaged in the door packaging assembly 300 is of a rectangular shape, where a length of each frame 308 is significantly greater than a width of each frame 308. As one example, to securely accommodate the doors 302, 304 within the door container component 310 positioned with the stacks 306 of frames 308 an additional, third stack 314 of doors 315 is configured within the door container component 310. The two stacks of the doors 302, 304 are positioned in a first direction (e.g. in a direction of the width of the frames 308), while the third stack 314 of doors 315 is positioned in a second direction substantially perpendicular to the stacks of the doors 302, 304 (e.g., in a direction of the length of the frames 308). For instance, the first and second stacks of doors 302, 304 may extend parallel to one another, while the third stack of doors 314 extends perpendicular to the first and second stacks of doors 302, 304. As can be seen in both
The door packaging assembly 300 accounts for the altered shape of the frames 308 while still accommodating, in the present example, twenty-five door assemblies in a single package that can be loaded onto a trailer.
Door packaging assembly 400 may have a similar configuration as that previously described for door packaging assembly 100. However, the door assembly packaged in door packaging assembly 400 has differently dimensioned frames and doors. Consequently, to still provide for an increased number of door assemblies able to be loaded onto a trailer (e.g., twenty-five door assemblies per packaging assembly), in the exemplary door packaging assembly 400 the configuration of the doors 402, 404 (within door container component 410) within the stacks 406 of frames 408 is altered.
The particular door assembly frame 408 in the illustrated example is approximately a square shape, where the lengths and widths of the frames 408 are substantially the same. As such, the cross-sectional area inside of the frame stacks 406 for positioning the door container component 410, and thus the doors 402, 404, can be reduced as compared to those door assemblies where the frame has one of the length and width significantly greater than the other. As a result, to accommodate the maximum number of doors 402, 404 within the area defined inside of the frame stacks 406, two door container components 410 are utilized one on top of the other, inside of the frame stacks 406 as shown in the example of
Embodiments can also include methods of packaging and/or shipping door assemblies. In one example, a plurality of doors are positioned onto a pallet. In addition, a plurality of frames are positioned onto the pallet such that the plurality of doors are positioned within the interior area defined by the plurality of frames. In a further example, the plurality of doors are positioned onto the pallet by loading the plurality of doors into a first door container component, with the plurality of frames positioned around a perimeter of the first door container component at one or more locations along the height of the first door container component. In one embodiment, a second plurality of doors can be loaded into a second door container component which is positioned on top of the first door container component, with the plurality of frames positioned around a perimeter of the first door container component, and in some cases around a perimeter of the second door container component when enough frames are stacked.
In some instances, a tray, such as that described herein, can be positioned onto the pallet as part of various methods, with the first door container component positioned on the tray so as to define a space between a perimeter of the first door container component and the tray. In such instances, one or more frames may be placed around the first door container component, such as by positioning one or more frames within the space between the perimeter of the first door container component and the tray such that one or more frames encompass a perimeter of the first door container component. In some embodiments, additional frames can be added on top of the initially positioned one or more frames. A frame sleeve can be positioned around the frames, and the exterior surface of the door packaging assembly may be securely banded.
Thus, embodiments of the invention are disclosed. Although the present invention has been described with reference to certain disclosed embodiments, the disclosed embodiments are presented for purposes of illustration and not limitation and other embodiments of the invention are possible. One skilled in the art will appreciate that various changes, adaptations, and modifications may be made without departing from the spirit of the invention.
