7. A coupling mechanism configured for readily detachably attaching a first utility module to a second utility module, the coupling mechanism comprising:
a female coupler at a face of one of the first utility module and the second utility module, the female coupler having a depressed locking location configured with at least one locking rib extending above a depressed surface and along a sliding path, and having an open edge facing in a first direction, wherein the at least one locking rib extends substantially parallel to the sliding path;
a male coupler at a face of the other one of the first utility module and the second utility module, the male coupler having a projecting locking location disposed in register with the depressed locking location and configured with at least one locking tongue extending along the sliding path at a second direction, opposite to the first direction, and configured for arresting engagement at a space between the locking rib and depressed surface; and
at least one locking member for arresting the first utility module with respect to the second utility module and preventing sliding displacement along the sliding path,
wherein the female coupler includes two locking ribs that each extend at a respective side edge of two neighboring depressed locking locations, the locking ribs disposed substantially parallel to the sliding path.
8. The coupling arrangement of claim 7 , wherein at least one locking latch arresting location is configured at a top face of one of the first utility module and the second utility module and at least one locking latch configured at a bottom face of the other of the first utility module and the second utility module, such that the at least one locking latch being axially displaceable between a projecting position in which it interlocks with the at least one locking latch arresting location for arresting the first utility module with respect to the second utility module and preventing sliding displacement along the sliding path, and a retracted position in which sliding displacement of the first utility module with respect to the second utility module along the sliding path is permitted.
9. A coupling mechanism for a utility assembly that comprises at least a first utility module and at least a second utility module, the coupling mechanism being configured between the first utility module and the second utility module; one of a top face of the first utility module and a bottom face of the second utility module includes at least one depressed locking location configured with a locking rib, and at least one locking latch arresting location; and the other one of the top face of the first utility module and a bottom face of the second utility module includes at least one projecting portion with a locking tongue disposed in register with the at least one depressed locking location, and at least one locking latch disposed in register with the at least one locking latch arresting location; and wherein at a locked position the bottom face at least partially rests over the top face, and the at least one projecting tongue is arrested by the corresponding at least one locking rib and the at least one locking latch is arrested by corresponding at least one locking latch arresting location, and further wherein disengaging the second utility module from the first utility module is facilitated by disengaging the at least one locking latch from the at least one locking latch arresting location, such that engaging the first and second utility modules into the locked position is provided by sliding the second utility module with respect to the first utility module along a sliding path defined by at least one of the at least one locking rib and the at least one locking tongue, wherein the at least one locking latch is spring biased and configured for normally projecting from a face of the respective first or second utility module.
10. The coupling mechanism of claim 9 , wherein (i) the at least one locking rib extends substantially parallel to the sliding path, (ii) the at least one locking rib extends substantially perpendicular and intersects the sliding path, (iii) a single locking rib extends at rear end of a depressed locking location and substantially perpendicular to the sliding path, (iv) wherein two locking ribs extend at side edges of a depressed locking location and disposed substantially parallel to the sliding path, or (v) two locking ribs each extend at a respective side edge of two neighboring depressed locking locations, the locking ribs disposed substantially parallel to the sliding path.
11. The coupling mechanism of claim 9 , further comprising a release latch for displacing the locking latch into disengagement from the locking latch arresting location can be disposed at a front face of the respective second utility module.
12. The coupling mechanism of claim 9 , wherein the at least one locking latch and the at least one locking latch arresting location are disposed at a front portion of the respective utility modules.
13. The coupling mechanism of claim 9 , wherein the at least one locking latch is configured for displacement in a direction substantially normal to a respective face of a utility module.
