[0054] As best illustrated by FIG. 7-FIG. 12, generally, each of the drawer assembly 14 bottom panel 20, first and second side panels 22a, 22b, the front panel 26, and the back panel 24 are affixed together by a pattern of a plurality of dowel holes 76 fitted with a plurality of semi-permanent dowel connectors 78 near the ends of each panel of the drawer assembly 14. The dowel connectors 78 are designed to easily and quickly connect coupled panel ends generally at right angles of the drawer assembly 14.

[0055] Referring to FIG. 3 and FIG. 4, in a version, each of the dowel connectors 78 consists of an elongated body 80 having a midsection 82, opposing sides 84, 86, and a plurality of longitudinally aligned truncated cone sections 88 extending form the midsection 82 being tapered towards the opposite side of the body 84, 86. Each dowel connector 78 adapted and configured to be press fit within the adjacently aligned pre-drilled dowel holes 76 between connected adjacent drawer assembly 14 panels.

[0056] In particular reference to FIG. 5, each of the truncated cone sections 88 at opposing sides 84, 86 of each dowel connectors 78 provides a general cylindrical profile having a diameter substantially equal or greater than the diameter of the pre-drilled dowel hole 76 within which the nylon dowel connector 78 is inserted at each opposing end 84, 86, thereby providing the friction type press fit which is semi-permanent. With reference to the version illustrated in FIG. 4, the dowel connector 78 may further provide a longitudinal slot 90 which extends the length of the dowel connector 78. The longitudinal slot 90 generally permits the truncated cone sections 88 to be inwardly compressed as the dowel connector 78 is inserted into the dowel holes 76 with the resilience of the dowel connector 78 material biasing the truncated cones sections 88 outwardly into a locking engagement with the inner wall surface 92 of the dowel hole 76 (FIG. 5).

[0057] Preferably, the dowel connectors 78 are manufactured from wood, plastic, and/or composite materials. Ideally, the dowel connectors 78 are made of an injection mold plastic such as nylon and may be pre-inserted into select drawer panels during manufacture in order to expedite the assembly of the RTA unit.

[0058] With reference now to FIG. 7-FIG. 10, in a first version, the drawer back panel 24 first and second side edges 56, 58 is affixed to the interior surface 44 of each respective first and second side panels 22a, 22b and the drawer front panel 26 interior surface 64 is affixed to the front edge 36 of each of the respective first and second drawer side panels 22a, 22b collectively forming a robust rectangular drawer assembly.

[0059] Referring now to FIG. 8, the drawer back panel 24 is generally a rectangular configuration having opposing interchangeable first and second side edges 56, 58, each providing two or more outwardly exposed dowel holes 76 configured for receipt and coupling of two or more dowel connectors 78. In the illustrated version, the drawer back panel 24 is mounted between and detachably connected to each of the interchangeable drawer first and second side panels 22a, 22b interior surfaces near the first and second side panel 22 rear edges 38 by way of aligned reciprocal dowel holes 76 and respective shared dowel connectors 78.

[0060] In the version, the drawer back panel 24 first and second side edges 56, 58 are connected by at least two vertically aligned dowel connectors 78 to the first and second side panel 22a, 22b interior surfaces 44 near the respective rear edges 38 forming a right-angle corner between the panels. In detail, the drawer back panel 24 first and second side edges 56, 58 form at least two outwardly exposed vertically aligned dowel holes 76 and the first and second side panel 22a, 22b interior surface 44 near the rear edge 38 forms two reciprocal inwardly exposed vertically aligned dowel holes 76 for receipt of a the shared dowel connector 78 connecting the drawer back panel 24 with the drawer first and second side panels 22a, 22b.

[0061] In a version, each of the first and second side panel 22a, 22b front edge 36 is connected by at least two vertically aligned dowel connectors 78 to the front panel 26 interior surface 64 near each respective first and second side edges 68, 70 forming right-angle corners between the panels. In detail, each of the drawer first and second side panel 22a, 22b front edge 28 forms at least two forward exposed vertically aligned dowel holes 76 for receipt of one more dowel connectors 78. Reciprocally, the drawer front panel 26 interior surface 64 near each respective first and second side edges 68, 70 define at least two aligned dowel holes 78 for receipt of aligned dowel connectors 78, thereby connecting the drawer front panel 26 with the first and second drawer side panels 22a, 22b.

[0062] In other versions of the invention, the drawer assembly 14 panel connections may be rearranged. Namely, each of the first and second side panel 22a, 22b rear edge 38 may be connected by at least two vertically aligned dowel connectors 78 to the drawer back panel 24 interior surface 52 and proximate the respective back panel 24 first and second side edge 56, 58. Moreover, the front panel 26 first and second side edges 68, 70 may be connected by at least two vertically aligned dowel connectors 78 to the respective drawer first and second side panel 22a, 22b interior surfaces 44 and proximate the respective first and second side panels 22a, 22b front edges 36.

[0063] Now with reference to FIG. 7, FIG. 10, and FIG. 11, in the version, the drawer assembly 14 first and second side panels 22a, 22b may further form a second longitudinal slot 92 positioned near the respective top edge 38 or opposing longitudinal edge operably shaped for receipt of the respective bottom panel 20 side edge 32, 34, thereby permitting the first and second side panels 22a, 22b to be interchangeable during assembly. In further terms, each of the interchangeable drawer first and second side panels 22a, 22b is designed such that they may be universally interchanged with the othermeaning each drawer 14 side panel 22a, 22b will function as either the left-side panel or the right-side panel. Because the left and right-side panels can be reciprocally interchanged, the likelihood of improper assembly is substantially reduced, particularly in view of the semi-permanent connection established by the plurality of dowel connectors 78. For example, the first side panel 22a can be utilized in place of the second side panel 22b and vice versa. Thus, allowing the consumer to assemble without the possibility of incorrectly assembling a side panel in the wrong position with a semi-permanent dowel connector 78.

[0064] In a version, the drawer back panel 24 interior surface 52 may further form a second longitudinal slot 94 parallel to the back panel 24 first longitudinal slot 25 and positioned proximate the top edge 60 operably shaped for receipt of the respective bottom panel rear edge 30. The parallel longitudinal slots 25, 94 positioned on the interior surface 52 allow the drawer back panel 24 to be inverted (flipped) and still align with the drawer bottom panel 20 rear edge 30 during assembly. Thus, reducing the likelihood of improper assembly of the drawer back panel 24 with the drawer bottom panel 20 throughout assembly.

[0065] A certain method of assembly of the drawer assembly 14 generally comprises the steps of: (a) positioning the first and second side panels 22a, 22b in a parallel configuration (see FIG. 10); (b) connecting the drawer back panel 24 with the first and second side panels 22a, 22b with one or more dowel connectors 78; (c) seating the bottom panel 20 rear edge 30, first and second side edges 32, 34 within respective first and second side panel 22a, 22b longitudinal slots 48 and the back panel 24 longitudinal slot 25; and (d) connecting the front panel 26 with the first and second side panels 22a, 22b with one or more nylon dowel connectors 78.

[0066] FIG. 13 illustrates a version of the fully assembled RTA furniture unit 10 providing the framework assembly 112 and the plurality of drawer assemblies 14 and is operably assembled by way of a plurality of dowel connectors 78 as described above. In the version, the framework assembly 112 forms an upright container for slidably supporting the plurality of drawer assemblies 14. In the version, the RTA furniture unit 10 is a roll cart which is supported by and moveable upon one or more castors 126 rotatably attached is the bottom of the framework 114.

[0067] Generally referring to FIG. 13-FIG. 22, the framework assembly 112 generally comprises one or more castor assemblies 114, a first and second side panels 116a, 116b, a back panel 118, and a top panel 120 which may be provided in a kit to the consumer for assembly or be preassembled forming a moveable set of drawers.

[0068] FIG. 14 is an illustrative perspective view of the one or more castor support assemblies 114. In the version, each castor support assembly 114 generally comprises a support member 122, castor inserts 124, and corresponding castors 126. As illustrated, each support member 122 comprises a rectangular body having opposing first and second side edges 128, 130, top surface 132, and bottom surface 134 supporting the castor inserts 124 downward towards the ground surface. Each of the first and second side edges 128, 130 providing at least two dowel holes 74 for providing receipt and seating of two or more dowel connectors 76 as described above. Each castor 126 is inserted and coupled with the requisite castor insert 124 in order to provide a rolling support to the roll cart 10.

[0069] Referring to FIG. 15-FIG. 18, each of the first and second side panels 116a, 116b generally have a front edge 136, a rear edge 138, a top edge 140, a bottom edge 142 forming a rectangular board having an interior surface 144 and an exterior surface 146. Each of the side panels 116a, 116b is generally mounted parallel and upright relative to the other side panel and the forward and rear castor support assemblies 114. A plurality of opposing drawer runners 148 are operably positioned on the interior surfaces 144 in order to provide support for each of the drawer assemblies 14.

[0070] Generally, as illustrated by FIG. 16, each of the castor support assemblies 114 connects to the first and second side panels 116a, 116b interior surfaces 54 proximate to the bottom edges 52 (See FIG. 15 and FIG. 16) using at least one dowel connector 78. The castor support assemblies 114 combine to form a platform for supporting the castors 126 and the overall framework 112 as shown in FIG. 17. In the illustrated version, two dowel connectors 78 are utilized at each side 128, 130 of each castor support member 122connecting reciprocal dowel holes 76 between the castor support member 122 and the requisite side panel 116a, 116b.

[0071] With reference to FIG. 19-FIG. 22, the top panel 120 generally consists of a rectangular board having a front edge 150, a rear edge 152, opposing first and second side edges 154, 156, a bottom surface 158, and a top surface 160. The top panel 120 is operably configured to be detachably connected to the top edge 140 of each of the mounted first and second side panels 116a, 116b. In the illustrated version, the bottom surface 158 comprises a plurality of dowel hole 76 near the perimeterconfigured to align and detachably connect by way of dowel connectors 78 to the top edge 140 of each of the first and second side panels 116a, 116b.

[0072] In a certain version, the top panel 120 comprises at least three predrilled dowel holes 76a, 76b, and 76c aligned downward along each respective opposing first and second side edges 154, 156. Uniquely, the distance between each predrilled hole 76 in series is unequal. For example, the in illustrated version, the distance L1 (FIG. 19FIG. 21) between hole 76a and hole 76b does not equal the distance L2 between hole 76b and 76c. For example, in the version, hole 76a and 76c are symmetrically placed at each corner of the top panel 120 and the hole 76b is offset along the line that connects holes 76a and 76c, thereby providing an unequal distance between each respective hole 76 in series.

[0073] In further detail, the top edge 140 of each of the first and second panels 116a, 116b reciprocally boast predrilled offset dowel holes 76 which align with the offset dowel holes 76 of the bottom surface 158 of the top panel 120 and are connected by way of at least six dowel connectors 78. Uniquely, the offset nature of the reciprocally predrilled dowel holes 76 force the correct orientation of the top panel 120 during assembly of the RTA furniture unit 10. For example, if the top panel 120 orientation was mistakenly reversed, the reciprocal center dowel holes 76b and dowel connector 78b would not align and therefore indicate improper orientation to the assembler. Because the dowel connectors 78 are semi-permanent, it is important that they are set in the correct reciprocal hole 76; otherwise, removal of a dowel connector 78 may cause unwanted damage. Thus, the offset distance between the dowel holes 76 force the assembler to assemble the top panel 120 in the correct orientation.

[0074] As best illustrated by FIG. 18, the framework assembly back panel 118 is generally a rectangular sheet and is configured to attach by way of nails along the rear outer perimeter of the framework assembly 112 formed by the rear edges 138 of the first and second side panels 116a, 116b as well as the rear edge 152 of the top panel 120 and the rear edge of the support member 122 of the rear castor support assembly 114.

[0075] A certain method of assembly of the framework assembly 14 may generally comprises the steps of: (a) positioning the forward and rearward castor support assemblies 114 in parallel (See FIG. 14); (b) attach the first and second side panels 116a, 116b in an upright parallel configuration to the forward and rearward castor support assemblies 114 utilizing one or more dowel connectors 78 (see FIG. 15 and FIG. 16); (c) connecting the framework top panel 120 with the top edge 140 of each of the first and second side panels 116a, 116b with one or more dowel connectors 78; (d) seating the framework back panel 118 via nails to the rear outer perimeter of the framework assembly 112.

[0076] The present invention can be made in any manner and of any material chosen with sound engineering judgment. Preferably, the RTA roll cart 10 is constructed of wood, plastic or other materials that are strong, lightweight, long-lasting, economical, and ergonomic.
