Description of Related Art 11 In current market of systemic cabinet, manufacturers focus on design 12 and process to increase the utility and transportation convenience of the 13 conventional systemic cabinet. Therefore, the conventional systemic cabinets 14 are mostly sold in assembling kits that have to be constructed by DIY and is secured immovably by tools to perform the final frames or cabinets after 16 consumers purchase them. Once the frames or the cabinets are worn too 17 much to use, the whole systemic cabinets will be dumped directly because it 18 is troublesome and time-consuming to disassemble the conventional 19 systemic cabinets into pieces. Therefore, the wasted conventional systemic 20 cabinets are not environmental friendly at all. 21 SUMMARY OF THE INNOVATION 22 A main objective of the present innovation is to provide a systemic 23 cabinet that has multiple boards each having mortises defined at two opposite 2 1 sides to make corresponding connecting pieces with supporting strength to 2 engage to achieve combination. By assembling the multiple boards with the 3 connecting pieces, the systemic cabinet is constructed quickly and 4 conveniently by wedging in operation of combination. The connecting pieces 5 have multiple types in design variation to provide different orientation 6 positioning efficiency and have supporting strength to make the composed 7 systemic cabinet firm and stable. Therefore, once one board worn and 8 needed to be replaced, only the worn board is changed by detaching the 9 relative connecting pieces to save other elements and to make the 10 replacement easy and environmental for future repair. 11 To achieve the foregoing objective, the systemic cabinet comprises 12 multiple boards and multiple connecting pieces between adjacent two of the 13 multiple boards, wherein the improvement of the systemic cabinet is that: 14 each of the multiple boards has multiple mortises defined at two 15 opposite sides; and 16 each of the multiple connecting pieces has two ends inserting into 17 two mortises on the adjacent two of the multiple boards respectively. 18 Further benefits and advantages of the present innovation will 19 become apparent after a careful reading of the detailed description with 20 appropriate reference to the accompanying drawings. 21 BRIEF DESCRIPTION OF THE DRAWINGS 22 Fig. 1 is an exploded perspective view of the first embodiment 23 showing a unit component of the systemic cabinet in accordance with the 24 present innovation; 3 1 Figs. 2A and 2B are perspective views showing two different types 2 of connecting pieces of the systemic cabinet in accordance with the present 3 innovation; 4 Fig. 3 is an exploded perspective view of the second embodiment of 5 the systemic cabinet in accordance with the present innovation; 6 Fig. 4 is an enlarged cross-sectional side view showing joints of the 7 connecting pieces and relative boards of the systemic cabinet in Fig. 3; 8 Fig. 5 is an exploded perspective view of the third embodiment 9 showing an enlarged unit component of the systemic cabinet in accordance 10 with the present innovation; 11 Fig. 6 is an exploded perspective view of the fourth embodiment of 12 the enlarged unit component of the systemic cabinet in accordance with the 13 present innovation; 14 Fig. 7 is an enlarged cross-sectional side view showing joints of the 15 connecting pieces and relative boards of the systemic cabinet in Fig. 6; 16 Fig. 8 is a perspective view of the third embodiment of the systemic 17 cabinet in Fig. 5, wherein the enlarged unit component does not have front 18 and rear boards; 19 Fig. 9 is an operational perspective view of the systemic cabinet in 20 Fig. 8 to illustrate the attachment of the rear board; 21 Fig. 9A is an enlarged cross-sectional view showing joints between 22 the rear board and a top board or a rear board; 23 Fig. 10 is a perspective view of the systemic cabinet in Fig. 9 to 24 show the attachment of the front board; 4 1 Fig. 11 is an explode perspective view of the fifth embodiment of the 2 systemic cabinet in Fig. 8 to combine with a drawer structure; 3 Fig. 12 is a perspective view of the systemic cabinet in Fig. 11; 4 Fig. 13 is a perspective view of the first embodiment of final 5 configuration to show the systemic cabinet arranged in a ladder-shape; 6 Fig. 14 is a perspective view of the second embodiment of final 7 configuration to show the systemic cabinet arranged in a T-shape; 8 Fig. 15 is a perspective view of the third embodiment of final 9 configuration to show the systemic cabinet arranged in a R-shape; 10 Fig. 16 is a perspective view of the fourth embodiment of final 11 configuration to show the systemic cabinet arranged in a J-shape; 12 Fig. 17 is a perspective view of the first embodiment of final 13 configuration to show the systemic cabinet composed of multiple enlarged 14 unit components arranged in a ladder shape; 15 Fig. 18 is a perspective view of a second embodiment of final 16 configuration to show the systemic cabinet composed of multiple enlarged 17 unit components with drawers arranged in vertical; and 18 Figs. 19-24 are perspective views of the third to seventh 19 embodiments of final configurations of the systemic cabinets. 20 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 21 A systemic cabinet in accordance with the present innovation is 22 composed of multiple boards and multiple connecting pieces. Each board has 23 multiple mortises defined at opposite sides respectively to combine the 24 corresponding connecting pieces with supporting strength by wedging to 5 1 perform compartments of the systemic cabinet. The connecting pieces have 2 multiple variations in design to provide orientation-positioning efficiency 3 and have supporting strength to make the composed systemic cabinet firm 4 and stable. Therefore, once one board is worn out, only the worn board is 5 replaced by detaching the connecting pieces to save other elements and to 6 make the replacement easy and environmental for future repair. 7 As shown in Fig. 1, a single unit compartment of systemic cabinet 8 comprises multiple boards 1 and multiple connecting pieces 4 at corners of 9 the unit compartment. 10 Each board 1 is rectangular and has a predetermined width based on 11 total configuration in design. Two opposite sides of the board 1 have four 12 mortises 11 defined at ends and four locking holes 12 defined on one face of 13 the board 1 to communicate with the mortises 11 respectively. Such boards 1 14 are uniform and defined as top boards, bottom boards, sideboards, bridging is boards, erecting boards, adjacent boards, widened boards as applied to 16 different orientation and modification mentioned below. 17 Each connecting piece 4 (as shown in Fig. 2A) has a locking body 2 18 and at least one tenon tube 3. The locking body 2 has multiple dovetail 19 grooves 21 defined on faces respectively to engage a dovetail-insertion 31 20 formed on the corresponding tenon tube 3. The dovetail-grooves 21 are not 21 entirely transversal through the face of the locking body 2 to reserve a block 22 section 22 (see Fig. 2A) to keep the corresponding tenon tube 3 engaged at a 23 limited position. Additionally, each tenon tube 3 has a protrusion 32 formed 24 on a top face to align with the locking hole 12 on the board 1. 6 1 As shown in Fig. 2B, another type of the connecting piece 4' is that 2 the tenon tube 3 and the locking body 2 are integrated into one-piece (Such a 3 connecting piece 4' is embodied to apply to widened cabinet with widened 4 boards). The connecting piece 4' has its length, the locking holes 33, and the 5 protrusions 32 arranged and decided by supporting strength to the widened 6 board 1. 7 With regard to assembly of the aforementioned multiple boards 1 and 8 the multiple connecting pieces 4 (as shown in Fig. 1), the tenon tube 3 at one 9 end of the connecting piece 4 inserts into the mortise 11 on one adjacent 10 board 1 until the protrusion 32 on the tenon tube 3 engages the locking hole 11 12 on the board. By having the multiple connecting pieces 4 each composed 12 of a locking body 2 and optional multiple tenon tubes 3, the boards 1 with 13 predetermined sizes are combined and constructed to perform a unit 14 component 5 (as shown Fig. 3, it is a narrow cabinet as an embodiment) is easily and conveniently by wedging. 16 When the unit component 5 is to add more compartments (as shown 17 in Figs. 3 and 4), the unit component 5 adds four tenon tubes 3 combined to 18 the corresponding locking bodies 2 at corners respectively by engaging the 19 dovetail-insertions 31 with the dovetail-grooves 21 snugly (as shown in Fig. 20 4). Moreover, each single tenon tube 3 inserts into the mortise 11 on 21 corresponding one of two erecting sideboards 1 and is positioned by locking 22 the protrusion 32 with the locking hole 12. Lastly, a bridging board 1 is 23 mounted over the two erecting sideboards 1 by attaching four connecting 24 pieces 4 at corners to perform the systemic cabinet with two components. 7 1 With regard to another embodiment of the systemic cabinet having 2 enlarged size in assembly (as shown in Fig. 5), the connecting piece 4' in 3 one-piece has two tenon tubes 3 arranged vertically to each other to insert 4 into two mortises 11 of two adjacent boards 1 respectively until the 5 protrusions 32 engage the locking holes 12. Four boards 1 are arranged one 6 by one in loop and eight connecting pieces 4' fix the corners for four boards 7 1 by above-mentioned ways to compose one compartment. Because the 8 locking body 2 and the two tenon tubes 3 of the connecting piece 4' are in 9 one piece, the connecting piece 4' provides sufficient supporting strength to 10 the widened boards 1 which are widened. By constructing and positioning 11 the widened boards 1 with the one-pieced connecting pieces 4', the unit 12 component 5' having one compartment is achieved (as shown in Fig. 6). 13 When the unit component 5' is to add more compartments (as shown 14 in Figs. 6 and 7), the unit component 5' adds four tenon tubes 3 combined to is the corresponding locking bodies 2 at corners respectively by engaging the 16 dovetail-insertions 31 with the dovetail-grooves 21 snugly (as shown in Fig. 17 7). Moreover, each single tenon tube 3 inserts into the mortise 11 on 18 corresponding one of two erecting sideboards 1 and is positioned by locking 19 the protrusion 32 with the locking hole 12. Lastly, a bridging board 1 is 20 mounted over the two erecting sideboards 1 by attaching four connecting 21 pieces 4' at corners to perform the systemic cabinet having two components. 22 The aforementioned unit compartment 5' is uncovered at front and 23 rear sides (as shown in Fig. 8) and is selectively mounted with a rear board 24 51 (as shown in Fig. 9). The rear board 51 has positioning protrusions 511, 8 1 512 wedging into corresponding through holes 14 defined on the top and 2 bottom boards 1 for positioning (as shown in Figs. 9 and 9A). Wherein two 3 of the positioning protrusions 512 at bottom are rectangular stubs and two of 4 the positioning protrusions 511 at top are arc-shaped to make the rear board 5 51 easily pushed into space between the top and bottom boards 1. Moreover, 6 the unit component 5' enables to be pivotally mounted with a front board 52 7 by hinges (as shown in Fig. 10, not numbered). Depending on the use of the 8 unit component 5', a drawer 53 is accommodated inside (as shown in Fig. 12) 9 and is composed of a U-shaped case 531 with a front plate 533 and a rear 10 plate 532 combined into one-piece (as shown in Fig. 11) so that the 11 combined drawer 53 is movably accommodated in the unit component 5'. 12 The aforementioned unit components 5 enable to be modified to 13 different arrangements such as a ladder-shape configuration 10 (as shown in 14 Fig. 13), a T-shape configuration 20 (as shown in Fig. 14), a R-shape 15 configuration 30 (as shown in Fig. 15), and a J-shape configuration 40 (as 16 shown in Fig. 16) for creating fun in decoration. With regard to unit 17 components 5' with widened size enable to be modified to different 18 arrangements such as a ladder-shape configuration 50 (as shown in Fig. 17), 19 multiple file cabinet configurations 60, 70 and 80 (as shown in Figs. 18-20), 20 a closet configuration 90 (as shown in Fig. 21), a staked configuration 100 21 for which each compartment has cover boards 1001 at front and rear faces 22 (as shown in Figs. 22 and 23), and a staked configuration 110 having 23 compartments with different sizes for creating more utility in use (as shown 24 Fig 24). 9 1 The aforementioned systemic cabinet has the following advantages 2 in assembly and practice: 3 1. By composing multiple boards with multiple connecting pieces to 4 perform the predetermined cabinet, the assembling operation is quick and 5 convenient and the combined cabinet is stable and firm. 6 2. Once the systemic cabinet is worn out too much to use, only the 7 broken parts of systemic cabinet can be replaced by detaching the relative 8 connecting pieces easily for material saving. Otherwise, the whole systemic 9 cabinet can be disassembled into pieces to reduce occupied space during 10 recycling process for environmental protection. 11 3. The unit components for the systemic cabinet are variable to 12 extend and create more embodiments both for utility purpose and for 13 decorative purpose. 14 Although this innovation has been described in its preferred form 1 with a certain degree of particularity, it is understood that the present 16 innovation of the preferred form has been made only by way of example and 17 that numerous changes in the details of construction and the combination and 18 arrangement of parts any be resorted to without departing from the spirit and 19 scope of the innovation. 20 10
