An opening/closing structure of a cover includes a casing and a rotatable cover. A shaft part and a bearing part are formed to one and the other of the casing and the cover, respectively. One of the shaft part and the bearing part is formed with one of a protrusion and a relief part on a part of an end surface in an axial direction, and the other of the shaft part and the bearing part is formed with the other of the protrusion and the relief part on a facing surface facing the end surface. The protrusion circumvents contact with the surface having the relief part when the cover is closed. When the cover is opened, from the closed state, by a particular angle, the protrusion contacts the surface so as to be applied with a resistant force against rotation of the cover.

A butt-joining and engaging structure that allows to a pair of columns to be connected. The butt-joining and engaging structure has a seat body with a first connecting portion and a through hole, a stop part extends from an inner wall of the through hole toward the center of the through hole, a connecting member has a pair of ends defining a plug-in portion and a second connecting portion, and a position limiting part protrudes from the abutment surface of the connecting member. The first connecting portion is adapted to be affixed to one of the pair of columns. The second connecting portion is adapted to be secured to an end of the other column.

A frame hooking and connecting structure includes a column, each side of which is formed with a first through hole, and a parallel second through hole. A first support rod is provided to hook the column. The two ends of the first support rod are extended with a fastening part, and the free end of the fastening part is connected with a first hook, which is hooked and positioned to the bottom edge of the first through hole, and the fastening part is attached to a corresponding end surface of the column. A second support rod is provided to hook the column. The ends of the second support rod are respectively extended with a second hook, and the free end of the second hook penetrates through the hollow portion and the second through hole into the column, and is locked to the bottom edge of the second through hole.

A modular furniture apparatus comprising: a cabinet having a cuboid shape having a flat top; a support component comprising a unitary body frame structure; a desktop panel having a flat upper surface and a flat opposing lower surface releasably connected to said top surface of said cabinet and said frame via suction cups.

A stand for a vivarium has a side wall with a cutout and at least one first magnet closure element arranged adjacent to the cutout. At least one cover is provided that is to be inserted into the cutout and at least partially covers the cutout in an installed position of the at least one cover in the cutout. The at least one cover has at least one second magnet closure element that in the installed position is arranged so as to correspond with the at least one first magnet closure element so that the at least one cover is secured in the cutout exclusively by magnetic forces interacting between the at least one first magnet closure element and the at least one second magnet closure element in the installed position.

There is provided a trim profile covering fixture with at least one side covering element with a longitudinal axis, for a trim profile of a movable furniture component, in particular a drawer, wherein the side covering element has at least one mounting projection which may be inserted into an assigned mounting location on the trim profile and is held there in the inserted state, wherein the mounting projection has at least one clamping jaw which may be braced by an inner surface of the mounting location.

An opening/closing structure of a cover includes a casing and a rotatable cover. A shaft part and a bearing part are formed to one and the other of the casing and the cover, respectively. One of the shaft part and the bearing part is formed with one of a protrusion and a relief part on a part of an end surface in an axial direction, and the other of the shaft part and the bearing part is formed with the other of the protrusion and the relief part on a facing surface facing the end surface. The protrusion circumvents contact with the surface having the relief part when the cover is closed. When the cover is opened, from the closed state, by a particular angle, the protrusion contacts the surface so as to be applied with a resistant force against rotation of the cover.
