DETAILED DESCRIPTION
[0030] A plurality of receptacles 10 are illustrated in a receptacle assembly 42 in FIG. 1. The receptacle assembly 42, hereinafter referred to as assembly 42, comprises at least two receptacles 10 joined at their respective coupling surface 18. On each receptacle, there are five surfaces. The bottom surface 22 serves as the base of the receptacle. The two collapsible surfaces 14 are generally parallel to each other's when the receptacle is expanded. The two coupling surfaces 18, also generally parallel to each other's, are generally perpendicular to the collapsible surfaces 14 when the receptacle is expanded. On each collapsible surface 14, there are two optional handles 38 which may be used by a person to manually transport or displace a receptacle 10 or an assembly 42. Each receptacle 10 has stiffening elements 24 installed on the exterior of a coupling surface 18. There are two vertical stiffening members 26 and one horizontal stiffening member 28 per group of stiffening elements 24. Those stiffening elements 24 provide a couple advantages, the most obvious ones being extended receptacles 10 stability when standing up and improved coupling strength when joining two receptacles 10.
[0031] FIG. 2 illustrates multiple individual receptacles 10 in a standing position adjacent to one another prior to be secured together in the assembly 42. In this embodiment, there are stiffening elements 24 on one coupling surface 18 of each receptacle 10 in an embodiment thereof, but there may also be stiffening elements 24 on both coupling surfaces 18 if desirable in an embodiment thereof.
[0032] FIG. 3 is illustrating the individual receptacles 10 of FIG. 2 except that the receptacles 10 are now joined at their coupling surfaces 18 to create an assembly 42 thereof.
[0033] Due to the flexible material 12 comprising the receptacles' 10 surfaces, individually or assembled, receptacles 10 may be compressed in order to obtain a more compact format 44 as can be seen on FIG. 4. This result is obtained by pressing opposite coupling surfaces 18 towards each other's until the coupling surfaces 18 aren't moving anymore. Compressed receptacles 10 may thus have a significantly reduced volume. Therefore, storing and transporting them may be easier. More so, receptacles 10 may be preassembled at a convenient time and location before being transported to the desired location. Set-up time might be saved in doing so. In order to expand the compressed receptacles 10, it is simply needed to pull apart coupling surfaces 18 until the collapsible surfaces 14 are fully stretched.
[0034] As stated above, three stiffening elements 24 are installed on the exterior side of a coupling surface 18 in the embodiment depicted in FIG. 5. The three stiffening elements 24 are respectively organized by two vertical stiffening members 26 and one horizontal stiffening member 28. As mentioned above, stiffening elements 24 are desirable for a multitude of reasons and, of the bunch, three are being described here within. First, they may provide extended receptacles 10 the ability to stand up on their own even when not filled. Second, they may allow for stronger and more durable receptacles' 10 couplings compared to fabric to fabric. And third, they may offer additional stability to an assembly 42 against external forces. Instead of using one complex shaped stiffening element to support a coupling side 18, three stiffening elements 24 per coupling side 18 are preferably used as it may be simpler to find straight planks of this sort and each may be assembled and/or disassembled individually if deemed necessary. The stiffening members 24 are generally made of readily available construction materials such as plywood planks of various dimensions. That said, they may also be made of any material with a structural integrity strong enough to fulfil the stiffeners 24 role and that is available to the task like wood, composite materials, recycled or non-recycled plastics or others.
[0035] There are a plurality of methods which may be used to install a stiffening member 24 to a receptacle 10. Out of this plurality, here are two that may be favored. The first one, as seen on FIG. 5, is by using patches 30 stitched to the exterior side of a coupling surface 18. Both vertical stiffening members' 26 patches 30 are installed on the side margins of a coupling surface 18 while the horizontal stiffening member's 28 patch 30 is installed on the upper margin of the aforementioned coupling surface 18. Generally, both vertical and horizontal patches 30 have a height of about 10 cm (4″) to 15 cm (6″). Even so, their height and length depends on the stiffeners 24 configuration described herein below and are typically slightly above stiffening elements 24 dimensions as to sufficiently cover them while still allowing different stiffening elements 24 dimensions. An opening, present at one or both patches 30 extremities, is used to insert or remove stiffening elements 24. More so, an opening may be stitched closed as to secure a stiffening element 24 inside its patch 30.
[0036] Another stiffeners 24 installation method that may be used and that is seen on FIG. 6 is by way of loops 34. Indeed, similar to patches 30, loops 34 are stitched on the exterior side of a coupling surface 18. Although their height generally depends on the used stiffeners 24 dimensions, they are of about 10 cm (4″) to 15 cm (6″) with a length of about a couple centimeters. Due to their physical characteristics, loops 34 might be preferred to patches 30 for multiple reasons. One of the advantages of this method is that it may require less fabric material than patches 30 for a given receptacle 10. Another advantage of this method is that it may allow visibility over parts of the stiffeners 24. Hence, the state of stiffeners 24, whether there is decay, material break or a misassembly, may be assessed even when receptacles 10 are assembled and/or fully filled. This method may also increase ventilation over the stiffening elements 24 which might reduce materials damage over time.
[0037] As mentioned above, there are other possible configurations of stiffening members 24. The first configuration, seen on FIG. 5, revolves around having the vertical stiffening members 26 go up to the upper margins of the coupling surface 18 and having the horizontal stiffening member 28 also on the upper coupling surface's 18 margin while being in-between the vertical stiffening members 26 with no contact. An advantage of this configuration is that the length range of stiffening members 24 may be quite large since they are not initially in contact with each other's, and thus, no extremely specific measure is deemed necessary. Another advantage of this configurations is that it may allow slight movements of the stiffening members 24, and therefore the receptacle 10 itself, before having their movement blocked once entering into contact with each other's. For this configuration, stiffening members' 24 dimensions may vary slightly, but general measures are as follow: about 15 cm by 86 cm (6″×34″) for the vertical stiffening members 26 and about 15 cm by 56 cm (6″×22″) for the horizontal stiffening member 28. The most commonly found thickness for planks of this type is around 5 cm (2″), but may vary depending on what's available.
[0038] Another configuration, seen on FIG. 7, revolves around having the horizontal stiffening member 28 covering the whole length, from one receptacle's collapsible surface 14 to the other, of the coupling surface's 18 upper margin. This stiffening member 24 is supported by two vertical stiffening members 26 that are installed on the outer side margins of their respective side of the coupling surface 18. The advantage of this configuration is that it may provide increased stability to a standing receptacle 10 as the stiffening members 24 are in a stable position the moment they are installed. For this configuration, it is preferred that vertical stiffening members 26 be of somewhat similar height while their width and thickness may slightly vary. On the other hand, the horizontal stiffening member 28 may have a bigger range of varying height, width and thickness as long as it may enter its loops 34 or patches 30. General measures are as follow: about 15 cm by 69 cm (6″×27″) for the vertical stiffening members 26 and about 15 cm by 81 cm (6″×32″) for the horizontal stiffening member 28. Thickness characteristics are similar to the other configuration abovementioned.
[0039] Joining two coupling surfaces 18 together may be achieved with a plurality of techniques, to which different types of fasteners may be used for each. Following are three techniques that may achieve this result. The first technique is the use of bolt assemblies 46, which generally comprises two washers, a nut and a bolt. As seen on FIG. 8, ten points are drilled at approximate locations on the stiffening members 24; for example, in the middle of the width and at about 5 cm, 13 cm, 46 cm and 84 cm (2″, 5″, 18″ and 33″) starting from the bottom along the length of the vertical stiffening members 26 and at about 20 cm (8″) and 41 cm (16″) along the length of the horizontal stiffening member 28. Bolts are thus inserted into those holes and the assembly 46 is made with the help of washers on both interior sides of the coupling surfaces and a nut to tighten it. The second technique is the use of a wood screw that is screwed at similar locations to the first technique. This technique is preferred if there are stiffening members 24 installed on both coupling surfaces 18 of a joining zone. Indeed, if there is no stiffening member 24 attached to a coupling surface 18, the screws passing through the fabric are required to support external forces applied to the receptacle 10 which could easily tear the fabric, especially if no washer is used. Finally, the third technique seen on FIG. 9 is the use of glue 50, typically a strong and water-resistant one. The glue 50 is applied on a length-wise line of both vertical 26 and horizontal 28 stiffening members if loops 34 are used. If patches 30 are used, then the glue 50 may be similarly applied, but on the exterior surface of the patches 30. While the use of any technique is left to the discretion of the user, the second technique is generally favored as it allows for a durable contact between two receptacles 10 while still being quick to execute.
[0040] The features of the present invention which are believed to be novel are set forth with particularity in the appended claims. Other and further aspects and advantages of the present invention will be obvious upon an understanding of the illustrative embodiments about to be described or will be indicated in appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
