The present appellation of the various sides of the tray and container 88 is from the point of view of a person standing in front of the front side 96 and looking at the tray and container arrangement 88 in the direction that extends from the front side 96 toward the back side 98. The front side of the container and the back side of the container can be referred to as opposite short sides of the container. The left side of the container and the right side of the container can be referred to as opposite long sides of the container.
[0050] Fig. 3 shows a top view of a tray 90 in accordance with an embodiment of the present disclosure. The tray 90 has a top side 104, a front side 106, a back side 108, a left side 110 and a right side 112. The tray 90 defines holders 82 configured (sized, dimensioned) to hold rockwool grow cubes (not shown), coco peat, or any other suitable substrate. The holders 82 define a bottom ledge 83 to prevent the substrate from falling out from the bottom side of tray 90. The tray 90 defines holes 105 that can be used by a worker to grab the tray 90. Each tray can define any suitable number of holders. Generally, a tray configured to grow large plants will have a smaller number of holders (or use a smaller number of holders) than a tray configured to grow smaller plants.
[0051 ] Fig. 4 show a bottom view the tray 90. Fig. 4 shows the bottom side 115 of the tray
90, the front side 106, the back side 108, the left side 110 and the right side 112. Also shown in Fig. 4 are the holders 82, the bottom ledges 83, reinforcement ribs 116, wheel housings 118, a tongue 120 and a wall 122. As described in greater detail elsewhere in the disclosure, the wheel housings 118 are configured to have wheels or wheel elements installed therein to enable the trays to roll along the length of the container 78 and, the tongue 120 is configured to connect to the wall 122 of an adjoining tray to interconnect the trays. The holders 82 are arranged in staggered rows or hexagonal configuration to allow each holder an equal space for the plants grown in the holders 82. The holders 82 can be in any suitable configuration, staggered or not. [0052] The front side 106 and the back side 108 can be referred to as opposite connector sides. Each of the opposite connector sides defines a respective connector element. Examples of connector elements are described herein. Although the opposite connector sides are shown as parallel, this need not be the case.
[0053] The left side 110 and the part of the grow tray that is next to left side 110 and that includes the left side wheel housings 118 can be referred to as a lateral side portion. The left side wheels housing and any wheel housed therein are aligned with the lateral side portion. The right side 112 and the part of the grow tray that is next to right side 112 and that includes the right side wheel housings 118 can be referred to as another lateral side portion. The right side wheels housing and any wheel housed therein are aligned with this lateral side portion. The two lateral side portions are parallel to each other can be referred to as parallel, opposite lateral side portions.
[0054] Fig. 5 shows a side cutaway view of the tray and container arrangement 88 of Fig. 1 , but with the tray assembly 80 vertically spaced apart from the container 78 for description purposes. The view is from the back side 98 of the tray and container arrangement 88. Fig. 5 shows the container 78, which has opposite sidewalls 124. The opposite sidewalls 124 have a top surface 126 and a guide barrier 128. The tray assembly 80 has trays 90 with wheels 130 housed in the wheel housings 118. The wheels 130 allow the trays to roll along the top surfaces 126 of the container 78. The guide barriers 128 prevent wheels 130 and the tray assembly 80 from rolling off the top surfaces 126. Fig. 6 shows the same view as Fig. 5, but with the tray assembly 80 positioned on the container 78, with the wheels on the top surfaces 126. Although shown as flat, one or both of the top surfaces 126 can have a concave shape or a groove to better maintain the tray assembly 80 aligned with the container 78.
[0055] The distance between the lateral side portions of the tray 90 corresponds to a distance between the top surfaces 126.
[0056] In other embodiments, wheels can be secured to the container 78 instead of the trays 90 and the trays 90 can have flat surfaces or concave surfaces or grooves against which the wheels of the container roll. For example, wheels could be secured to the container and positioned where the top surfaces 126 are located, and the flat surfaces could be defined at the right and left sides of the tray and configured to contact the wheels of the container when the tray is placed at the top opening of the container.
[0057] Fig. 7 shows a top view of the tray 90. The top side 104 of the tray 90 can have markings 91 that indicate the direction the tray 90 must be oriented when being positioned on the container 98. Fig. 8 shows a side view of the tray 90 taken from the right side 112 of the tray 90, with the wheels 130 installed in the wheel housings 118. In some embodiments, the wheels can have a diameter of 2 cm and a width of 2 mm. Wheels of any suitable dimensions are considered to be within the scope of the present disclosure. Other than wheels, any suitable type of wheel elements or rolling mechanism (roller mechanism), such as bearing, rollers, etc. secured to the tray 90 can be used. Fig. 9 shows a side view of the tray 90 taken from the front side 106. Shown in Fig. 9 is a recess 30 defined by the front side 106. As disclosed below, the recess 30 is dimensioned for the tongue 120 of the back side 108 of another tray 90 to be inserted therein.
[0058] The following paragraphs describe how a series of trays 90 can be interconnected to form the tray assembly 80 of Fig. 2. In Figs. 10A, 10B, 11 A, 11 B, 12A, 12B, 13A-13D and 14A-14C, the trays are shown in composite views that include a cross section of the tray 90 taken along the line X-X of Fig. 7 and the wheels 130. The container 78 is shown in a side view but with a cutaway that omits the guide barrier 128 shown in Figs. 5 and 6.
[0059] Referring to Figs. 10A, a first tray 90A is positioned on the container 78 with the wheels 130 on the top surface 126. A second tray 90B is shown in a tilted orientation as it is brought toward the first tray 90A. The tray 90A is oriented with its tongue 120 pointing toward the back side 98 of the container and tray arrangement 88 and the tray 90B is oriented with its back side 108 and tongue 120 pointing toward the front side 106, the recess 30 and the wall 122 of the first tray 90A. Fig. 10B is a close-up view of Fig. 10A and shows the wall 107 of the back side 108 and the tongue 120 of the second tray 90B and the front side 106, the recess 30 and the wall 122 of the first tray 90A. Fig. 10B also shows that the tongue 120 defines a boss 121. The boss 121 and the wall 107 of back side 108 of the second tray 90B define a notch 123 (or a gap) between the boss 121 and the wall 107. As will described below, the notch 123 of the second tray 90B can be positioned to hold the wall 122 of the first tray 90A.
[0060] Fig. 11A shows the second tray 90B in a tilted orientation, with the bottom side 115 of the tray 90B in contact with the top surface 126. The contact between the bottom side 115 of the second tray 90B with the top surface 126 is shown at contact region 132. Also shown in Fig. 11A is the back side of 108 of the second tray 90B in contact with or apposed to the front side 106 of the first tray 90A and the tongue 120 of the second tray 90B in the recess 30, below the wall 122 of the first tray 90A. Fig. 11 B is a close-up view of Fig. 11A and shows the wall 107 and the tongue 120 of the second tray 90B, the front side 106, the recess 30 and the wall 122 of the first tray 90A, and the contact region 132. Fig. 11 B also shows the notch 123 of the second tray 90B. By pivoting the second tray 90B toward the container 78, the notch 123 of the second tray 90B will capture and hold the wall 122 of the first tray 90A, thereby interconnecting the trays 90A and 90B. [0061] Fig. 12A shows the first tray 90A interconnected to the second tray 90B. Both the first tray 90A and the second tray 90B are positioned on the container 78 with the wheels 130 of the first tray 90A and the second tray 90B on the top surface 126. Fig. 12B is a close-up view of Fig. 12A and shows the notch 123 of the second tray 90B latched onto the wall 122 and holding the wall 122 of the first tray 90A, thereby interconnecting the first tray 90A and the second tray 90B. Fig. 12B also shows the tongue 120 of the second tray positioned in the recess 30 of the first tray 90A.
[0062] Figs. 13A-13D show the tray and container assembly 88 with additional trays being added to the tray assembly 80. In Fig. 13A, a third tray 90C is being added to the tray assembly 80 by positioning the back side 108 of the tray 90C against the front side of the tray 90B and subsequently pushing, in the direction indicated by the arrow 134, the tray assembly 80 toward the back side 98 of the tray and container assembly 88, to arrive at the configuration shown in Fig. 13B. When in the configuration of Fig. 13B, the third tray 90C is pivoted downward, in the direction indicated by the arrow 136, to interconnect the third tray 90C to the second tray 90B, as shown in Fig. 13C. The interconnection of the third tray 90C to the second tray 90B is effected in the same way the second tray 90B is connected to the first tray 90A, as described above in relation to Figs. 10A, 10B, 11A, 11 B, 12A and 12B.
[0063] From the configuration shown in Fig. 13C, a fourth tray 90D, a fifth tray 90E and a sixth tray 90F are added following the same steps as those described in relation to the adding of the third tray 90C to the tray assembly 80. The final configuration of the present example is shown in Fig. 13D with the wheels 130 of all the trays positioned on top surface 126 of the tray 78.
[0064] Figs. 14A-14C show the tray and container assembly 88 and the removal of a tray from the tray assembly 80. Fig. 14A shows the same configuration as that shown in Fig. 12D, but with an arrow 138 showing the direction in which the sixth tray 90F and the tray assembly 80 are to be pulled, i.e. toward the front side 96 of the tray and container assembly 88. The sixth tray 90F is also to be tilted in the direction indicated by the arrow 140 before or simultaneously with the sixth tray 90F and the tray assembly 80 being pulled. In this scenario, the angle at which the sixth tray 90F can be pivoted must be such that the sixth tray 90F is still coupled to the fifth tray 90E, i.e., the angle must be such that the wall 122 is still partly held within the notch 123 (Fig. 10B, 11 B and 12B).
[0065] Fig. 14B shows the tray and container assembly 88 after the sixth tray 90F and the tray assembly 80 have been pulled toward the front side 96 of the tray and container assembly 99 and after the sixth tray 90F has been pivoted upward to uncouple the sixth tray 90F from the fifth tray 90E, i.e. to pivot the tray 90F such that the notch 123 no longer latched to the wall 122 (Figs. 10B, 11 B and 12B). Fig. 14B also shows an arrow 142 that indicates a direction toward which the sixth tray 90F can be pulled to be removed from the tray and container arrangement 88. Fig. 14C shows the sixth tray 90F after being pulled away from the tray assembly 80.
[0066] The tray and container arrangement 88 can have any suitable dimensions. For example, the tray 90 can have a length of 508 mm, a width of 716 mm and a height of 27 mm. The trays 90 can define any suitable number of holders 82 (plant holders), for example 60 and have any suitable number of wheels, for example four wheels per side. The distance between the holders 82 in as same row and the spacing between the rows can have any suitable value, for example 77 mm. The holders 82 shown in the figures are open bottom holders but this need not be the case.
[0067] In other embodiments, the interconnection between trays 90 can be effected by other types of connections such as, for example, magnetic connections, hook connections, clip connections, etc.
[0068] As an example, Fig. 15 shows a tray 93 in accordance with another embodiment of the present disclosure. The tray 93 is similar to the tray 90 shown in Figs. 7, 8 and 9, but instead of having a tongue and notch at the back side 108 and a recess and wall at the front side 106, the tray 93 has back magnetic element 144 at the back side 108 and a front magnetic element 146 at the front side 106.
[0069] Fig. 16 shows two spaced apart trays, tray 93A and tray 93B, positioned on a container 78. The tray 93B is to be moved/pushed/rolled in the direction of the arrow 148, toward tray 93B, to interconnect the trays 93A and 93B to each other. The back magnetic element 144 is lower than the magnetic element 146 to allow the positioning of the back magnetic element 144 of the tray 93B below the front magnetic element 146 of the tray 93A when the tray 93B is rolled/moved toward the tray 93A. Fig. 17 shows the tray 93B interconnected to the tray 93A.
[0070] Alternatively, the tray 93B and the tray 93A can be interconnected to each other by positioning the tray 93B at an oblique angle, as shown in Fig. 18, and pushing, along the direction indicated by the arrow 148, the tray 93B toward the tray 93A until the back magnetic element 144 of tray 93B is below the front magnetic element 146 of tray 93A. Tilting the tray 93B toward the container 98 causes the magnetic element 144 of tray 93B to become magnetically coupled to the magnetic element 146 of tray 93A, to interconnect the trays 93A and 93B. [0071] In some embodiments, the back magnetic element 144 and the front magnetic element 146 can be magnets oriented such that the magnetic polarity of the back magnetic element 144 of the second tray 93B faces the opposite magnetic polarity of the front magnetic element 146 of the tray 93A when the magnetic elements 144 and 146 are vertically aligned with each other to allow the trays 93A and 93B to interconnect to each other through the magnet of one of the trays and the magnet of the other tray. In other embodiments, one of the magnetic elements 144 and 146 can be a magnet and the other of the magnetic elements 144 and 146 can be made of materials that includes a magnetic material (e.g., a ferromagnetic material such as iron) to allow the trays 93A and 93B to interconnect to each other through the magnet of one of the trays and the ferromagnetic material of the other tray.
[0072] Each of the back magnetic element 144 and the front magnetic element 146 can include any number of magnets or magnetic material elements. In some embodiments, the magnetic coupling between the back magnetic element 144 of one tray and the front magnetic element 146 of the tray to which it is connected should be sufficiently strong to allow a person to pull a tray assembly along a container, by pulling on the endmost tray of the tray assembly.
[0073] In the embodiment of Figs. 16-18, the trays can be loaded onto the container 78 at the front side 96 of the tray and container arrangement 89 and unloaded at the back side 98 of the tray and container arrangement 89. As an example, starting from the configuration shown at Fig. 17, a worker positioned at the back side 98 of the tray and container arrangement can unload the tray 93A from the container 78 by tilting the back side of the tray 93A upwards to separate the front magnetic element 146 of the tray 93A from the back magnetic element 144 of the tray 93B and by subsequently pulling the tray 93A away from the tray 93B.
[0074] In the embodiment of Figs. 15-18, the front magnetic element 146 is above the back magnetic element 144. This need not be the case: the front magnetic element 146 can be below the back magnetic element 144 without departing from the scope of the present disclosure. Such an embodiment also allows the unloading of trays at the back side of the tray and container arrangement.
[0075] In other embodiments, trays can be interconnected using a hook and eye mechanism, an example of which is shown at Figs. 19, 20 and 21. Fig. 19 shows a top view of an embodiment of a tray 95 in accordance with the present disclosure. The tray 95 that has eyes 150 formed at the back side 108 and hooks 152 formed at the front side 106. Fig. 20 shows a side view of the tray 95 shown at Fig. 19. Fig. 21 shows a side view of two trays 95A and 95B interconnected through the hook and eye mechanism. In Fig. 21, a first tray 95A has the hooks 152 inserted into the eyes 150 of a second tray 95B, thereby interconnecting the trays 95A and 95B. The trays 95A and 95B are shown positioned on a container 78. Fig. 22 shows the tray 95B with its front side 106 tilted above its back side 108, and with its eye 150 below the hook 152 of the tray 95A. Pivoting the front side 106 downward will connect the tray 95B to the tray 95A to form the tray assembly shown in Fig. 21.
[0076] Figs. 23 and 24 show another embodiment of a tray 95 in accordance with the present disclosure, where the hook 153, are curved upward contrary to the hook 152 (curved downward), shown in the embodiment of Figs. 19 and 20. As shown in Fig. 25 and 26, having the hook 153 curved upward allows the tray 95B to be interconnected to the tray 95A by positioning the eyes 150 of the tray 95B over the hooks 153 of the tray 95A, as shown in Fig. 25, and subsequently lowering the tray 95B to catch the hooks 153 of the tray 95A, as shown Fig. 26.
[0077] In the embodiment of Figs. 23-26 the trays can be loaded onto a container a one end of the container and unloaded at the opposite end of the container. As an example, starting from the configuration shown at Fig. 26, a worker positioned at the end of the container closest to the hooks 150 of the tray 95A can unload the tray 95A from the container 78 by tilting the back side of the tray 95A upwards to un-hook the tray 95B and by subsequently pulling the tray 95A away from the tray 95B.
[0078] Fig. 27 shows a flowchart of an embodiment of a method of loading a plurality of grow trays on a container, in accordance with the present disclosure. Each grow tray of the plurality of grow trays has a top side, a bottom side, a front side, a back side, and a pair of lateral sides extending from the back side to the front side. The front side of each grow tray comprises a front connector element and the back side of each grow tray comprises a back connector element.

At the front side of the container, positioning 200 a first grow tray on the container, with the rolling mechanisms of the first grow tray on the top surfaces of the container. At step 202, pivoting the back side of a second grow tray upward with respect to the front side of the second grow tray. At step 204, apposing the front side of the second grow tray to the back side of the first grow tray. At step 206, pivoting the back side of the second tray downward with respect to the front side of the second tray to connect the front connector element of the second tray to the back connector element of the first tray and to position the rolling mechanisms of the second tray on the top surfaces of the container. At step 208, pushing the second grow tray toward the back side of the container to cause the first grow tray and the second grow tray to roll on the top surfaces of the container. At step 210, pivoting the back side of a third grow tray upward with respect to the front side of the third grow tray. Then, at step 212, apposing the front side of the third grow tray to the back side of the second grow tray; and, at step 214, pivoting the back side of the third grow tray downward with respect to the front side of the third grow tray to connect the front connector element of the third grow tray to the back connector element of the second grow tray and to position the rolling mechanisms of the third grow tray on the rolling surfaces of the container.
[0081] Fig. 28 shows a flowchart of a method of removing a plurality of grow trays from a container, in accordance with the present disclosure.
[0082] Each grow tray of the plurality of grow trays has a top side, a bottom side, a front side, a back side, and a pair of lateral sides extending from the back side to the front side. The front side of each grow tray comprises a front connector element. The back side of each grow tray comprising a back connector element, the lateral sides of each grow tray of the plurality of grow trays having a rolling mechanism coupled thereto and extending from the bottom side of the grow tray.
