Abstract

A systemic cabinet is composed of multiple boards and multiple connecting pieces. Each board has multiple mortises defined at sides respectively to combine the corresponding connecting pieces with supporting strength by wedging to form a configuration of the systemic cabinet. The connecting pieces have multiple types in design variation to provide orientation-positioning efficiency and have supporting strength to make the composed systemic cabinet firm and stable. Therefore, once one board is worn out, only the worn board is replaced by detaching the connecting pieces to save other elements and to make the replacement easy and environmental for future repair.

Claims (25)

1. A systematic cabinet comprising:

i) first and second boards each with two opposite lateral sides, wherein each of the first and second boards includes mortises defined at two ends of each of said two opposite lateral sides thereof, with each mortise extending in a mortise direction for a preset length; and

ii) connecting pieces for inserting into said mortises when joining the first and second boards, wherein each of said connecting pieces includes:

ii.a) a solid locking body of six congruent faces, with the locking body including first and second dovetail-grooves separately defined on one of said six congruent faces without transversally grooving, with a central block section maintained between each of the first and second dovetail grooves and another of said six congruent faces; and

ii.b) first and second tenon tubes engaged with the locking body, wherein each tenon tube has four lateral faces slideably received in the mortise direction in mortises of the first and second boards, with the first and second dovetail grooves extending perpendicular to the mortise direction and to the central block section, with the locking body having solid cross sections perpendicular to the first and second dovetail-grooves.

2. The systemic cabinet

as claimed in claim 1 , wherein the first and second

tenon tubes are integrally formed onto said locking body for engaging said mortises when joining said boards.

3. The systemic cabinet as claimed in claim 2 , wherein each of said connecting pieces further comprises:

a third tenon tube having a dovetail for engaging one of said first and second dovetail-grooves of said locking body.

4. The systemic cabinet as claimed in claim 2 , wherein each of said boards further includes a locking hole communicating with said mortises; and

each of said first and second tenon tubes includes a protrusion corresponding to said locking hole for engaging the locking hole.

5. The systemic cabinet as claimed in claim 4 , further comprising a rear board of a top side, a bottom side and four lateral sides including multiple positioning protrusions formed at said top side and said bottom side thereof respectively; and

each of said first and second boards includes multiple through holes for engaging said positioning protrusions of said rear board.

6. The systemic cabinet as claimed in claim 2 wherein each of the first and second tenon tubes includes a non-lateral face having a dovetail received in one of the first and second dove-tail grooves of the locking body.

7. The systemic cabinet as claimed in claim 1 wherein each of the first and second tenon tubes includes a non-lateral face having a dovetail received in one of the first and second dove-tail grooves of the locking body.

8. The systemic cabinet as claimed in claim 7 wherein the locking body and the first and second tenon tubes are arranged in an L-shape.

9. The systemic cabinet as claimed in claim 8 , wherein each of said connecting pieces further comprises:

a third tenon tube having a dovetail for engaging one of said first and second dovetail-grooves of said locking body.

10. The systemic cabinet as claimed in claim 7 , wherein each of said boards further includes a locking hole communicating with said mortises; and

each of said first and tenon tubes includes a protrusion corresponding to said locking hole for engaging the locking hole.

11. The systemic cabinet as claimed in claim 7 , further comprising a rear board of a top side, a bottom side and four lateral sides including multiple positioning protrusions formed at said top side and said bottom side thereof respectively; and

each of said first and second boards includes multiple through holes for engaging said positioning protrusions of said rear board.

12. The systemic cabinet as claimed in claim 1 , wherein each of said boards further includes a locking hole communicating with said mortises; and

each of said first and tenon tubes includes a protrusion corresponding to said locking hole for engaging the locking hole.
