A compact joining and leveling system for parts of furniture and furnishing items with a bottom and a shoulder includes, in combination, a front-foot unit and a rear-foot unit, wherein each front- and rear-foot unit includes a leveling group with a regulation mechanism in height that can be maneuvered with tools, wherein the leveling group of the front-and rear-foot units can be actuated from the front with respect to the piece of furniture through the space between the base and the floor, wherein the system also includes a connection group for stably interconnecting the bottom and the shoulder through a blocking element, and wherein the connection group can be actuated from the front with respect to the piece of furniture through the space between the bottom and the floor.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

This invention is involved in the manufacturing technology, which is a kind of easy assembly metal bed frame. This metal bed frame includes metal frames, the first main slats, supports and supporting rods. The ends of the bed frame are welded with metal plate connections which have elliptic holes at both ends. The bed frame consists of two main bars at both sides, setting fixed slot at the inner side. At both ends, the first main slats are the mobile connection and the second main salts, which can be vertically connected with support by using bolts to link through the fixed holes at the upper and down sides of the second main slats, are the fixed connection. In the middle of the bed frame, the bars are insetted elliptic nuts on one side and bolts on the other side and links the supporting rods at the bottom. Using plastic fasteners to connect the bed frame and slats is easy to operate and durable. Supports not only insure the stability and safety of the metal bed frame, but also create an opportunity to use light slats in order to reduce the weight of bed frame.

A joining device with minimum visibility for parts of furniture and furnishing items, in particular connecting a first panel to a second panel, which must be moved towards each other in an approach direction to bring the edge of one panel buffered in a tightening position against a surface of the other panel, includes a blocking group and a connection group assembled on the panels. The blocking group is inserted inside a seat contained in the thickness of the panel on which the blocking group is applied, and the seat has a longitudinal axis perpendicular to the approach direction, and extending from an edge towards the inside of the panels.

A crib assembly includes a frame to support a mattress, an enclosure having sides defining an enclosure area, and an attachment system including a first and second attachment mechanisms. A first side of the enclosure has a first end and a second end. The first end is configured to removably attach via the first attachment mechanism to a first corner of the enclosure and the second end is configured to removably attach via the second attachment mechanism to a second corner of the enclosure. The first attachment mechanism includes (a) a first bolt located at the first end of the first side or the first corner of the enclosure and (b) a first slot located at the first end of the first side or the first corner of the enclosure, opposite the first bolt. The second attachment mechanism includes (a) a second bolt located at the second end of the first side or the second corner of the enclosure and (b) a second slot located at the second end of the first side or the second corner of the enclosure, opposite the second bolt. The first and second bolts are dimensioned to be slidably received within the respective first and second slots to removably attach the first and second ends of the first side to the respective first and second corners of the enclosure.

In order to provide a connecting device for connecting two components, which is simple to manufacture and enables a stable and reliable connection of the two components, it is proposed that the connecting device comprises a main body which comprises a receiving channel extending through the main body for accommodating a fixing element, wherein the receiving channel is preferably accessible at one end by way of an insertion opening of the main body and/or preferably at a (further) end by way of a fixing opening of the main body, wherein the main body preferably further comprises an actuating opening that is different from the insertion opening and/or the fixing opening, by way of which in particular the fixing element arranged in the receiving channel is preferably accessible for the actuation thereof.

An enclosure can have an enclosure body, the enclosure body can include an enclosure frame, and a first enclosure flange. The enclosure can have a center post having a first end and an opposite second end, the first end can include a first center post flange having a hole extending therethrough. The enclosure can include a gasket having a gasket hole therethrough, and a threaded fastener to threadingly engage the hole. The threaded fastener can be configured to rotate in a first direction while threadingly engaged with the hole, and the threaded fastener can contact the first enclosure flange to increase a distance between the first enclosure flange and the first center post flange in order to receive the gasket.

A bedstead includes a headboard, a footboard and two sideboards to form a bed frame. The two sideboards are connected with bed legs. A plurality of bed beams are mounted between the two sideboards. Each sideboard includes two connected side boards. The bed legs are connected to four corners of the bed frame. Aback of the headboard is formed with an accommodating cavity. After being disassembled, the side boards, the footboard, the bed beams and the bed legs are placed into the accommodating cavity. The bedstead can be assembled easily. It is more convenient to pack and transport the bedstead after being disassembled, thereby saving the transportation cost.
