A rolling module structure and a method for use therewith are introduced. The rolling module structure includes a carrier and at least one rolling member. The rolling member is fitted to the carrier to form a rolling module structure. The rolling module structure is fitted to a moving target, allowing the moving target to move smoothly because of the rolling member.

The invention refers to a furniture panel assembly (200, 200′ 200″, 200′″) comprising a furniture panel (300, 300′ 300″, 300′″) and a wheelhouse cassette (100, 100′, 100″, 100′″). The furniture panel (300, 300′ 300″, 300′″) has a slot (23) extending in a plane in parallel with and at least partly between the major surfaces of the furniture panel (300, 300′ 300″, 300′″) and the wheelhouse cassette (100, 100″, 100″, 100′″) is positioned in the slot (23). The wheelhouse cassette (100, 100′, 100″, 100′″) comprises a wheelhouse (1; 1′; 1″; 1′″) and a wheel (2) adapted to be inserted into and retainably engage the wheelhouse (1; 1′; 1″; 1′″).

A rolling storage rack for a closet includes a base storage cart and base tracking. The base storage cart has a front, a back, sides that are open, and wheels attached to a bottom of the base storage cart at approximately each corner on the bottom of the base storage cart. The base tracking is configured to be mounted on a floor of the closet. The base tracking is configured to allow at least rear wheels of the wheels of the base storage cart to roll on top of the base tracking from a stored position in the closet to an access position pulled out from the closet.

A refrigerator having an improved structure to maintain the humidity in a drawer. The refrigerator includes a storage chamber, a drawer configured to be inserted to or withdrawn from the storage chamber, a cover configured to cover an upper part of the drawer, and a rail device configured to guide the drawer to slide in a front-rear direction with respect to the cover and to allow the cover to be located in the storage chamber and to be moved upward with respect to the drawer when the drawer is withdrawn.

A screw-free drawer structure includes a front board, a rear board, two side boards, and a bottom board. The side boards are foldably connected to opposite sides of the bottom board. An upper end of a junction of each side board and the rear board is detachably connected through an elastic fastener that is in snap-fit with a fastener hole. A junction of each side board and the front board is detachably connected through an elastic expansion member that is elastically expanded to be in snap-fit with an engaging hole. Therefore, the screw-free assembly of the drawer structure is realized, and the assembly of the drawer structure is convenient and easy.
