Abstract
A shelf unit includes four leg rods and two assembly mechanisms. The leg rods extend in an up-down direction, are spaced apart from each other, and are equally divided into two leg pairs. Each of the assembly mechanisms includes a first connecting subunit that is mounted to a top end of a respective one of the leg pairs, and a second connecting subunit that is mounted to a bottom end of the respective one of the leg pairs. One of the first and second connecting subunits of each of the assembly mechanisms has two engaging holes each of which is configured to be non-circular. The other one of the first and second connecting subunits of each of the assembly mechanisms has two through holes each of which corresponds in position to a respective one of the engaging holes of the assembly mechanism in the up-down direction.
Claims5
A shelf device, comprising:
- two shelf units stacked in an up-down direction, each of the shelf units including
- a leg rod mechanism that includes four leg rods extending in the up-down direction and spaced apart from each other, the leg rods being equally divided into two leg pairs,
- a board mechanism that is mounted among the leg rods, and
- two assembly mechanisms that are respectively mounted to the leg pairs, each of the assembly mechanisms including a first connecting subunit that is mounted to a top end of the respective one of the leg pairs, and a second connecting subunit that is mounted to a bottom end of the respective one of the leg pairs, one of the first connecting subunit and the second connecting subunit of each of the assembly mechanisms having two engaging holes each of which extends therethrough in the up-down direction and is configured to be non-circular, the other one of the first connecting subunit and the second connecting subunit of each of the assembly mechanisms having two through holes each of which extends therethrough in the up-down direction and corresponds in position to a respective one of the engaging holes of the assembly mechanism in the up-down direction, the leg rods of one of the shelf units being connected to and being located on the leg rods of the other one of the shelf units, the engaging holes of one of the shelf units being respectively aligned with the through holes of the other one of the shelf units in the up-down direction;
- and
- four fastening units each of which is mounted to a respective one of the engaging holes of the one of the shelf units and a respective one of the through holes of the other one of the shelf units that are aligned in the up-down direction, each of the fastening units including a first fastening member that is irrotatably mounted to the respective one of the engaging holes, and a second fastening member that extends through the respective one of the through holes and the respective one of the engaging holes and that is removably connected to the first fastening member so that the shelf units are fastened in the up-down direction.
