IV. Detailed Description

[0027] Referring now to the drawings wherein the showings are for purposes of illustrating the present subject matter only and not for purposes of limiting the same, and wherein like reference numerals are understood to refer to like components, FIGURES 1-5 show views of panels of one example of a storage receptacle. FIGURES 6-11 show various non-limiting examples of a storage receptacle stacking system. FIGURES 12-13 show one non-limiting example of a mechanical fastener usable in a storage receptacle stacking system. FIGURES 14- 19 show a non-limiting example of a receptacle and the panels and fasteners. As used herein the terms top, bottom, left, right, and back are used for ease of understanding and convenience, but are not to be intended to be limiting: the apparatus may have any orientation in space.

[0028] FIGURE 6 shows one non-limiting example of a first receptacle 110 of a storage receptacle stacking system 100 which comprises a set of receptacles 105. The first receptacle 110 is a hollow, open rectangular prism. The first receptacle 110 is defined by a back panel 122 and a set of side panels 130. In the non-limiting example of first receptacle 110, the first receptacle 110 is a rectangular prism and, the set of side panels 130 has four panels, one for each side of the rectangular prism base defined by the rectangular back panel 122. In other examples, a receptacle may be a hexagonal prism where the set of side panels has six panels, or a triangular prism where the set of side panels has three panels, or a trapezoidal prism where the set of side panels has four panels, or a prism form of a Penrose tile (that is, a prism having the cross-section of a Penrose tile), or other geometry chosen with good engineering judgment. Referring to FIGURES 7-11, as will be described further herebelow the set of receptacles 105 may comprise a first receptacle 110, a second receptacle 111, and, optionally, one or more other receptacles 112, 113, 114, 115, 116, 117, 118, 119.

[0029] Referring now to FIGURES 1-6, in the non-limiting example shown, the back panel 122 is substantially planar, rectangular, and has: a first back panel surface 123; a second back panel surface 124 opposite the first back panel surface 123; a top edge 125; a bottom edge 126 opposite the top edge 125; a right edge 127 connecting the top edge 125 and the bottom edge 126; and a left edge 128 opposite the right edge 127, connecting the top edge 125, and the bottom edge 126. In the non-limiting example shown, the set of side panels 130 has a top panel 132, a bottom panel 134, a left panel 136, and a right panel 138.

[0030] In the non-limiting example shown, the top panel 132 is adjacent to, parallel to, and engaged with the top edge 125 of the back panel 122, and extends perpendicularly from the first back panel surface 123. As shown in FIGURE 1, the non-limiting example of the top panel 132 may be substantially planar and rectangular. The non-limiting example of the bottom panel 134 is adjacent to, parallel to, and engaged with the bottom edge 126 of the back panel 122, and extends perpendicularly from the first back panel surface 123. As shown in FIGURE 2, the non-limiting example of the bottom panel 134 may be substantially planar and rectangular. The non-limiting example of the left panel 136 is adjacent to, parallel to, and engaged with the left edge 127 of the back panel 122, and extends perpendicularly from the first back panel surface 123. As shown in FIGURE 3, the non-limiting example of the left panel 136 may be substantially planar and rectangular. The non-limiting example of the right panel 138 is adjacent to, parallel to, and engaged with the right edge 128 of the back panel 122, and extends perpendicularly from the first back panel surface 123. As shown in FIGURE 4, the non-limiting example of the right panel 138 may be substantially planar and rectangular. Each of the panels 132, 134, 136, 138 in the set of side panels 130 may be engaged with the back panel by one or more of an adhesive, or a mechanical fastener. An adhesive may be any adhesive chosen with good engineering judgment. A mechanical fastener may be a screw, a bolt, a nut, a clip, a clamp, a pin, a variety of split ring captured pin fastener 140, or other fastener chosen with good engineering judgment.

[0031] Referring now to FIGURES 6-13, each receptacle 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 in the set of receptacles 105 is removably engaged to at least one other receptacle by a first set of mechanical fasteners 140. For each receptacle 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 at least one of the panels in the set of side panels 130 is adjacent to and parallel with at least one of the panels in the set of side panels 130 of another receptacle. For each receptacle 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 any one of the panels in the set of side panels 130 may be engaged in the alternative with any one of the panels in the set of side panels 130 of any other receptacle. In some non-limiting examples, each of the receptacles in the set of receptacles 105 is substantially identical in size and shape. In other non-limiting examples, one or more of the receptacles in the set of receptacles 105 is substantially different in size, or is substantially different in shape, or is substantially different in both size and shape from one or more of the other receptacles in the set of receptacles 105.

[0032] In some non-limiting examples, each of the receptacles in the set of receptacles 105 is substantially identical in size and shape such that each is congruent with each other, each receptacle is a prism having an axis of elongation, the receptacles are collectively arranged in an array in which each axis of each prism is parallel with each other axis of each other prism and the array tessellates the plane perpendicular to the axes of the prisms in a repeating pattern. It is to be understood that these repeating patterns are periodic.

[0033] In some non-limiting examples, the set of receptacles 105 is defined by a first sub-set of receptacles 107 and a second sub-set of receptacles 109 wherein each of the receptacles in the first sub-set of receptacles 107 is substantially identical in size and shape to every other receptacle in the first sub-set of receptacles 107 such that each of the receptacles in the first sub-set of receptacles 107 is congruent with each of the other receptacles in the first subset of receptacles 107 and wherein each of the receptacles in the second sub-set of receptacles 109 is substantially identical in size and shape to every other receptacle in the second sub-set of receptacles 109 such that each of the receptacles in the second sub-set of receptacles 109 is congruent with each of the other receptacles in the second sub-set of receptacles 109, but wherein the receptacles in the first sub-set of receptacles 107 differ in size or shape or both from that of the receptacles in the second sub-set of receptacles 109. In some of these latter non- limiting examples, each receptacle in the first sub-set of receptacles 107, and each receptacle in the second sub-set of receptacles 109 is a prism having an axis of elongation, the receptacles in the first sub-set of receptacles 107, and in the second sub-set of receptacles 109 are collectively arranged in an array in which each axis of each prism is parallel with each other axis of each other prism, and the array tessellates the plane perpendicular to the axes of the prisms in a nonrepeating pattern. It is to be understood that these non-repeating patterns are aperiodic. One non-limiting example of such an aperiodic pattern is a Penrose tiling such as the Penrose P2 tiles, also known as the kite and dart tiles. The kite tile is a quadrilateral whose four interior angles are 72, 72, 72, and 144 degrees. The dart tile is a non-convex quadrilateral whose four interior angles are 36, 72, 36, and 216 degrees.

[0034] A split ring captured pin fastener 140 may be used to provide operational engagement within a receptacle, such as fastening a side panel to a back panel in a receptacle. The fasteners 140 may be pressed through a panel, such as without limitation, press through a side panel into a top panel or bottom, or pressed through the back panel into a side panel, to facilitate engagement. Alternatively, fasteners may be held in threaded engagement with one or more panels by male or female threads. Alternatively, fasteners may be held in engagement with one or more panels by spurs or clips or clamps.

[0035] A split ring captured pin fastener 140 may be used to provide operational engagement between two receptacles, such as fastening a side panel of a first receptacle 110 to a side panel of a second receptacle 111. Referring now to FIGURE 12, in one non-limiting example a split ring captured pin fastener 140 may comprises a male pin 150 and female housing 160. The male pin 150 defines an axis of elongation 151 and may comprise a female

engagement portion 152 and a part engagement portion 153. The part engagement portion 153 is adapted for engagement with a first part. The first part may be a back panel 122, or a panel in a set of side panels 130, or another part of a receptacle 110. In the non-limiting example shown in FIGURE 12, the part engagement portion 153 comprises the fastening elements 156 of a screw. In certain examples, the part engagement portion 153 may comprise the fastening elements of a screw, a bolt, a nut, another threaded component, a clip, a clamp, spurs, or another fastener chosen with good engineering judgment. The female engagement portion 152 is adapted for engagement with the female housing 160. In the non-limiting example shown in FIGURE 12, female engagement portion 152 is a substantially cylindrical shaft comprising a narrow saddle 154. The saddle 154 is adapted for engagement by a split ring 170. In the non-limiting example shown as the male pin is initially inserted through the split ring, it opens the split ring 170, deforming it elastically, and increasing the elastic energy stored in the split ring 170. As the male pine 150 is further inserted, the split ring will closes around the narrow saddle 154 and thereby engage the male pin. When the saddle 154 of male pin 150 is engaged with the split ring 170, the split ring creates substantial resistance to axial movement of the male pin 150 along the axis of elongation 151 and thereby retains the male pin 150 in the split ring 170. This engagement between the male pin 150 and the split ring 170 is vibration resistant and will not disengage unless a critical disengagement force is applied to input deformation energy into the split ring 170 sufficient to permit the male pin to be removed. In the non-limiting example shown in FIGURE 12, the split ring 170 is captured by and held substantially fixed by and within the female housing 160 so that as the split ring 170 retains the male pin 150 in the split ring 170, it also retains the male pin 150 within the female housing 160. The female housing 160 in turn comprises a part engagement feature 164. The part engagement feature 164 is adapted for engagement with a second part. The second part may be a back panel 122, or a panel in a set of side panels 130, or another part of a receptacle 110. In the non-limiting example shown in FIGURE 12, the part engagement feature 164 comprises the fastening elements 166 of a screw. In certain examples, the part engagement feature 164 may comprise the fastening elements 166 of a screw, a bolt, a nut, another threaded component, a clip, a clamp, spurs, or another fastener chosen with good engineering judgment. By engaging the first part to the part engagement portion 153 of the male pin 150, and by engaging the second part to the part engagement feature 164 of the female housing 160, the nature of the engagement of the first part to the second part may be controlled by the nature of the engagement of the male pin 150 to the female housing 160, which as noted above is a function of the engagement of the male pin 150 to the split ring 170.

[0036] The split ring 170 may comprise an elastic material such as a polymer, or elastic metal or elastic metal alloy. The elasticity of the material of which the split ring is comprised may be chosen with good engineering judgment. As shown in FIGURES 12-13, in certain non-limiting examples, the split ring 170 may comprise an axis of elongation 171 that, as installed in the split ring captured pin fastener 140 will coincide with axis 151. As shown in FIGURES 12-13, in certain non-limiting examples, the split ring 170 may comprise a ring having an inside diameter and an outside diameter. The split ring 170 may comprise an insertion chamfer 172 at the top of the inner diameter. An insertion chamfer 172 may be angled with respect to the axis of elongation 171 by some insertion angle 173 and may provide a sloping surface in the direction of insertion, that is, the direction along which the male pin 150 is moved in order to insert it into the split ring 170, in order to facilitate insertion. The split ring 170 may comprise a desertion chamfer 174 at the bottom of the inner diameter. A desertion chamfer 174 may be angled by some desertion angle 175 with respect to the axis of elongation 171 and may provide a sloping surface in the direction of desertion, that is, the direction along which the male pin 150 is moved in order to withdraw it from the split ring 170, in order to facilitate withdraw. As shown in FIGURE 12, in certain non-limiting examples, the male pin 150 may comprise an insertion chamfer 157 and a desertion chamfer 158. An insertion chamfer 157 may be angled with respect to the axis of elongation 151 and may provide a sloping surface in the direction of insertion, that is, the direction along which the male pin 150 is moved in order to insert it into the split ring 170, in order to facilitate insertion. A desertion chamfer 158 may be angled with respect to the axis of elongation 151 and may provide a sloping surface in the direction of desertion, that is, the direction along which the male pin 150 is moved in order to withdraw it from the split ring 170, in order to facilitate withdraw. In certain examples, one or more of the inside diameter 177 of the split ring 170, the outside diameter 178 of the split ring 170, the height 179 of the split ring 170, the material of which the split ring is comprised, the elasticity of the material of which the split ring is comprised, the angle of the insertion chamfer 172 with respect to the axis of elongation 151, the angle of the desertion chamfer 174 with respect to the axis of elongation 151, the angle of the insertion chamfer 157 with respect to the axis of elongation 151, the angle of the desertion chamfer 158 with respect to the axis of elongation 151, may be chosen to provide the desired force or range of forces needed to engage the male pin 150 with the female housing 160 and to provide the desired force or range of forces needed to disengage the male pin 150 from the female housing 160.

[0037] One type of split ring captured pin fastener 140 is available from Lockdowel, Inc. in Fremont, California.

[0038] In the non-limiting example shown in FIGURES 1-11, each receptacle 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 may be assembled by fastening the left and right side panels to the top and bottom panels, and then fastening the back panel to the top, bottom, left, and right side panels. Either the left and right side panels or the top and bottom panels may have openings for receiving fasteners, such as mechanical fastener 140, for allowing each receptacle

110, 111, 112, 113, 114, 115, 116, 117, 118, 119 to be engageable to another receptacle 110,

111, 112, 113, 114, 115, 116, 117, 118, 119. In one aspect, the receptacles 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 may be stackable using spring pins or other mechanical fasteners 140, which can be inserted into the top and bottom surfaces of the left and right side panels. The receptacles 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 may also be connected side to side as well. The outer surfaces of the left and right side panels may have openings which can receive additional fasteners for connecting receptacles 110, 111, 112, 113, 114, 115, 116, 117, 118, 119 side to side.

[0039] With reference now to FIGURES 7-11, the completed receptacles 110, 111,

112, 113, 114, 115, 116, 117, 118, 119 can be stacked and connected in a variety of ways.

FIGURE 7 shows two receptacles 110, 111 stacked on top of each other. In one aspect, spring pins are inserted into a first receptacle 1 10 having two openings on the top surface of both the left and right side panels. A second receptacle 111, with two openings on the bottom surface of both the left and right side panels is connected to the first receptacle 110 and the two are connected via the spring pins or mechanical fasteners 140.

[0040] FIGURE 14 shows one non-limiting example of a second non-limiting example of a first receptacle 210 of a storage receptacle stacking system which comprises a set of receptacles 205. The first receptacle 210 is a hollow, open rectangular prism. The first receptacle 210 is defined by a back panel 222 and a set of side panels 230 and a set of top and bottom panels 290. In the second non-limiting example of first receptacle 210, the first receptacle 210 is a rectangular prism and, the set of side panels 230 has two panels, the set of top and bottom panels 280 has two panels. The two side panels 230 and the top and bottom panels 280 collectively define each side of the four sides of the rectangular prism base defined by the rectangular back panel 222. The set of receptacles 205 may comprise a first receptacle 210, a second receptacle, and, optionally, one or more other receptacles.

[0041] Referring now to FIGURES 16-18, in the non-limiting example shown, the back panel 222 is substantially planar, rectangular, and has: a first back panel surface 223; a second back panel surface 224 opposite the first back panel surface 223; a top edge 225; a bottom edge 226 opposite the top edge 225; a right edge 227 connecting the top edge 225 and the bottom edge 226; and a left edge 228 opposite the right edge 227, connecting the top edge 225, and the bottom edge 226. In the non-limiting example shown, the set of side panels 230 has a left panel 236, and a right panel 238. In the non-limiting example shown, the set of top and bottom panels 280 has two panels, top panel 232, a bottom panel 234.

[0042] In the second non-limiting example shown, the top panel 232 is adjacent to, parallel to, and engaged with the top edge 225 of the back panel 222, and extends

perpendicularly from the first back panel surface 223. As shown in FIGURE 16, the non- limiting example of the top panel 232 may be substantially planar and rectangular. The non- limiting example of the bottom panel 234 is adjacent to, parallel to, and engaged with the bottom edge 226 of the back panel 222, and extends perpendicularly from the first back panel surface 223. As shown in FIGURE 16, the non-limiting example of the bottom panel 234 may be substantially planar and rectangular. The non-limiting example of the left panel 236 is adjacent to, parallel to, and engaged with the left edge 227 of the back panel 222, and extends

perpendicularly from the first back panel surface 223. As shown in FIGURE 16, the non- limiting example of the left panel 236 may be substantially planar and rectangular. The non- limiting example of the right panel 238 is adjacent to, parallel to, and engaged with the right edge 228 of the back panel 222, and extends perpendicularly from the first back panel surface 223. As shown in FIGURE 18, the non-limiting example of the right panel 238 may be substantially planar and rectangular. Each of the panels 232, 234, 236, 238 may be engaged with the back panel 222, or the top panel 232, or the bottom panel 234, by one or more of an adhesive, or a mechanical fastener. An adhesive may be any adhesive chosen with good engineering judgment. A mechanical fastener may be chosen from the fasteners 191 shown in Figure 19. The fasteners 191 may comprise a cinch joint 193 comprising a female cinch joint component 194, and a male cinch joint component 195, or a spring pin 197, or a combination thereof. A mechanical fastener may further comprise a screw, a bolt, a nut, a clip, a clamp, a pin, a variety of split ring captured pin fastener 140, or other fastener chosen with good engineering judgment.

[0043] Referring now to FIGURES 14-19, in the second example, each receptacle 210 in the set of receptacles is removably engaged to at least one other receptacle by a first set of mechanical fasteners such as, without limitation, mechanical fastener 197, or mechanical fastener 193, or mechanical fastener 140. Receptacle 210 may be joined to other similar receptacles 210 in a variety of orientations. The top and bottom panels 234, 232 comprise connection apertures 246, 247, 248 on each of three edge surfaces 256, 257, 258. In the non-limiting second example, the size and shape of the edge surface 256, 257, 258 are the same between one another and the location and size of the connection apertures 246, 247, 248 on each edge surface are the same; the edges are all congruent and the geometry of the connection apertures 246, 247, 248 on any edge surface 256, 257, 258 would coincide with the geometry of the connection apertures 246, 247, 248 on any other edge surface 256, 257, 258 if superimposed thereon. The result is that the receptacle 210 comprises a set of connection apertures that permit the receptacle 210 to be connected with a similar receptacle 210: in parallel; perpendicular; or anti-parallel to one another as viewed looking down at the top panel 232. That is, a first receptacle 210 may be arranged with a similar second receptacle 210 with the left side panel 236 of the first receptacle 210 adjacent to the right side panel 238 of the second receptacle 210 such that the connection apertures 246 of the first receptacle 210 are operatively aligned with the connection apertures 248 of the second receptacle 210 and such that a set of spring pins 197 or other mechanical fastener chosen with good engineering judgment can be operatively engaged with the operatively aligned connection apertures to join the first receptacle 210 and second receptacle 210 in parallel, with their front openings 215 facing the same direction. Similarly, a first receptacle 210 may be arranged with a similar second receptacle 210 with the left side panel 236 of the first receptacle 210 adjacent to the back panel 222 of the second receptacle 210 such that the connection apertures 246 of the first receptacle 210 are operatively aligned with the connection apertures 247 of the second receptacle 210 and such that a set of spring pins 197 or other mechanical fastener chosen with good engineering judgment can be operatively engaged with the operatively aligned connection apertures to join the first receptacle 210 and second receptacle 210 perpendicularly, with their front openings 215 facing at 90 degrees to one another. Similarly, a first receptacle 210 may be arranged with a similar second receptacle 210 with the left side panel 236 of the first receptacle 210 adjacent to the left side panel 236 of the second receptacle 210 such that the connection apertures 246 of the first receptacle 210 are operatively aligned with the connection apertures 246 of the second receptacle 210 and such that a set of spring pins 197 or other mechanical fastener chosen with good engineering judgment can be operatively engaged with the operatively aligned connection apertures to join the first receptacle 210 and second receptacle 210 in anti-parallel, with their front openings 215 facing opposite one another.

[0044] In the second non-limiting example, each of the receptacles 210 may be substantially identical in size and shape to one another such that each is congruent with each other. In the second non-limiting example, each receptacle 210 is a prism having an axis of elongation, the receptacles are collectively arranged in an array in which each axis of each prism is parallel with, perpendicular to, or anti-parallel with each other axis of each other prism.

[0045] In some examples, the receptacles are formed in such a way that the panels are operatively engaged by mechanical fasteners and the operatively engaged panels shroud the mechanical fasteners connecting them, such that the mechanical fasteners operatively engaging the panels not visible in the finished receptacles.

[0046] Further examples consistent with the present subject matter are set out in the following numbered clauses.
