The disclosed technology relates generally to boxes, and more specifically to expandable and collapsible boxes.
Collapsible or telescopic containers (Cooperative Patent Classification (CPC) B65D21/086) are, of course, known in the art. However, these containers often require one to add or remove or disconnect components in order to change the size. Or, the size can be changed in only one Euclidean vector direction (e.g. increase the height vertically or horizontally, but not both).
U.S. Patent Publication 2010/0074723 to Lancon, for example, discloses a collapsing cargo box. The box has a top container and bottom container which fit over each other. The top container telescopes outward using a rail system to be above the bottom container. This reference discloses the concept of vertical rails which are expanded to enlarge the box in one direction only. U.S. Pat. No. 2,223,074 to Martin discloses a window box which is hung from a window. The box slides against itself to make the box wider or narrower. This reference shows the concept of horizontally widening a box only. This is accomplished by pulling it apart. U.S. Pat. No. 7,823,739 to Sadkin et al. discloses a collapsible shipping container with bi-folding sidewalls which collapse in accordion style. In this manner, the box can be expanded and lowered in height.
What is needed in the art is way to improve upon the prior technology and make it more versatile as well as easier to use. For example, while the Martin box can be expanded in one direction to fill in a window, if one's window is a different height, the Martin box will not be sufficient. One would need to procure an entirely separate box, adding to costs of production, warehousing, shipping, and so forth since so many different size boxes are needed. If a “one size fits all” box could be made to fit any shape space, this would be preferable.
A box which is independently expandable in both a horizontal and vertical direction while retaining a rigid structure (at least each outer wall is unbendable/unbent) in embodiments of the disclosed technology, is made up of four different distinct and individual pieces. Each form a quadrant of the box and slides to connect to two other pieces which are the two pieces in adjacent quadrants. Each piece further forms at least a part of two walls of the box which are perpendicular to each other.
The pieces can be slid into place by way of a pin extending through a slot to connect them. If one pulls two sections away from each other or pushes two sections closer to each other, then the pin and slot move with respect to one another accordingly. The pin and slot are on adjacent pieces such that pulling or pushing them moves two of the four pieces toward or away from each other, expanding the box in the horizontal or vertical direction. Further, the horizontal and vertical movement are uncoupled from each other so that one can expand in either direction without expanding in the other, or expand partially in one direction and partially in another, and so forth in any combination of no expansion, partial expansion, or full expansion. No expansion, or a collapsed state is defined as one in which two pieces (quadrants) are pushed as close together as possible (without causing damage). In such an embodiment, the respective pin and slot cannot be pushed further as the pin abuts an end of the slot at a side of the slot which is furthest away from an opposite side of the piece with the respective pin. A partial expansion is where a pin is between two extreme ends of a respective slot, or where two pieces (quadrants) can be pulled apart further or pushed together further. A full expansion is the opposite of a collapsed state where two pieces (quadrants) are pulled apart from each other as much as possible and a pin is against a side of the slot which is closed to an opposite side of the piece with the pin.
In some embodiments, the box is at least partially closed on five sides and open on a sixth side, the sixth side being surrounded by front panels which extend past each horizontal-most extent of at least a left wall and right wall of the box. The left wall has a portion of two of the four separate pieces and the right wall has a portion of two (other) of the four separate pieces. The front panels can be placed or positioned inside a window and a majority of the left wall and the right wall are outside of the window. So too, a majority of the box can be outside the window and box walls can fill a space of the window, which for purposes of this disclosure, is any rectangular or substantially rectangular space within a larger surface.
The front panels can form a closed rectangle when the box is fully collapsed (“fully” meaning both vertically and horizontally). This rectangular space can open into the box without interruption (no other part of the box structure or box itself is in the opening). This rectangular space can be substantially the size of an opening in a window where the box is mounted. When the box is expanded, at least partially in the horizontal and the vertical direction, the rectangular space is increased in size both in the x and y direction through the front panels each becoming spaced apart from one another.
In more detail, the four pieces, in embodiments of the disclosed technology, are a first piece, a second piece, a third piece, and a fourth piece. The first piece is connected to the second and third. The second, to the first and fourth. The third, to the first and third. The fourth, to the second and fourth. The first piece forms a part of a top side and left side. The second forms a part of the top side and right side. The third forms a part of the left side and bottom side. The fourth forms a part of the right side and bottom side. The cardinal directions (top, bottom, left, right, etc.) are relative to each other and their arrangement within the box.
In the above embodiment, the first piece and fourth piece are without connection to one another, and the second piece and the third piece are without connection to one other. A back side is formed from a part of each of the four pieces, in embodiments, and each of the four pieces can have a diagonal cross bar, which is diagonal with respect to the most elongated sides of the sides, top and bottom. This diagonal cross bar closes a part of the back side when used.
When in a collapsed configuration or condition, the collapsed side (the top side, left side, right side, and/or bottom side) is of double thickness compared to when (fully) expanded.
Another way of describing the box of embodiments of the disclosed technology is by way of the arrangement of connectors between the sides. A first side of the box has a pair of horizontally extending rails and a pair of vertically extending rails. A second side, opposite the first side, has an additional pair of horizontally extending rails and an additional pair of vertically extending rails. Each of these rails further has at least one pin passing through a slot such that the at least one pin and the slot are movable in one plane to expand or contract the box in such a respective plane.
One or more pins can be fixed to a side of the box. Each pair of rails has, in embodiments of the disclosed technology, a first rail and a second rail on an opposite side of the box from each other. Each rail slides (is slidable, that is, capable of being slid) with respect to each pin such that the box is expandable in a first of a vertical or horizontal direction without expanding in a second of a vertical or horizontal direction. Or, one can expand the box in both the vertical and the horizontal direction simultaneously (defined as “in one motion” or “such that there is expansion in both directions at the same time”).
The box can be sized to fit within an opening of a window. When it is, a portion of the box can be placed interior to the window and abutted against the window by front panels which define (surround) an opening into the box. Such an opening is transverse to both the vertical and the horizontal direction of expansion, described previously. These front panels can be on a side of one of the pairs of horizontally extending rails and one of the pairs of vertically extending rails. Each other side of the box, other than a side with the opening into the box, is at least partially closed by walls which extend between at least two rails of one the collective group of rails afore-described (the horizontally and the vertically extending rails).
Any device or step to a method described in this disclosure can comprise or consist of that which it is a part of, or the parts which make up the device or step. The term “and/or” is inclusive of the items which it joins linguistically and each item by itself. “Substantially” and “generally” is defined as “at least 95% of the term being described” and any device or aspect of a device or method described herein can be read as “comprising” or “consisting” thereof.
A box which is expandable vertically and horizontally is disclosed. The box can be expanded both vertically and horizontally simultaneously, or in only one of these directions. This is accomplished by pulling/pushing opposite sides further/closer to each other. Rails which at least partially extend between respective opposite sides allow such an expansion/or contraction, the rails, in embodiments, having a pin of one section of the box held within a slot of an adjacent section of the box. The box, in embodiments, is made up of four separate pieces, each being one quadrant (top & left, top & right, bottom & left, bottom & right) of the box. Such a box can be expanded/collapsed to fit within a window and hold an air conditioner there-in.
Embodiments of the disclosed technology will become clearer in view of the following description of the figures.
Starting with
Now referring specifically to the embodiment shown in
With the exception of the front portions 140, 142, 240, 340, 342, and 440, the pieces can be substantially identical or fully identical, within a tolerance level acceptable in the industry. Each has at least one rail 104, 114, 224, 234, 304, 314 and/or at least one pin 216, 316, 416, and 426. Within each rail is a slot 105, 115, 225, 235, 305, and 315. Each pin slides within each rail. That is, a rail and respective pin are movable with respect to each other such that pin can move between extreme ends of each slot. Thus, for example, rail 234 has a slot 235 in which pin 416 can move. Assuming the bottom of the sheet where
In this manner, the box can be expanded vertically by moving pieces 100 and 200 upward with respect to pieces 300 and 400, or horizontally by moving pieces 100 and 300 away from pieces 200 and 400. When this is done, the rails move past the pins such that the pins become closer to an end of a respective slot which is closest to the piece which is moving away. As the vertical and horizontal movement are independent from each other, each can be done without affecting the other degree of movement.
The above will become clearer in view of the description of
In
Now returning to the description of
The above can be seen by comparing
Now jumping to
In order that the box fills or substantially fills the open space created in the window when the movable portion 20 is lifted from a bottom of the window (or to fill another opening in a wall or the like), the box is expanded. Here, one can see some of the rails 104 and 304, for example, as the box is partially expanded in the horizontal direction to be sized to fill the space horizontally. So too, vertically the box has been expanded partially to fill the space in the vertical direction. As such, the box can fill the entirety of a rectangular space. The rectangular space filled by the side walls of the box just behind the front panels (e.g. by side wall 452 and the corresponding side walls of pieces 100, 200, 300, and 400) can be any size rectangular having a length between the smallest and largest horizontal side of the box and a height between the smallest and largest vertical side of the box. Thus, if the box can expand between 1 unit of measure and 10 units of measure both horizontally and vertically, then the space filled by the box could be, for example, 1×10, 10×1, 5×5, 3×7, 7×3, and so forth.
Referring back to
The back side, opposite the opening created between the front panels, can further be closed off by mesh or other walls or wall portions such as the diagonal beams 118, 218, 318, and 418 shown in
