This museum showcase comprises a bearing frame and fixed and/or openable walls supported by the bearing frame. The bearing frame comprises a platform that includes joints connected to horizontal beams. The fixed and/or openable walls of the showcase are supported only by the joints. The weight of the walls is supported by the joints, whereas the horizontal beams are not subjected to significant stresses. It is thus possible to design the showcase in a particularly simple and therefore quick manner, choosing the lengths of each beam according to the dimensions of the showcase and leaving the support of the weights to just the joints.

The present invention relates to a device for fastening a table top on a substructure which comprises a fastening means which can be screwed to the underside of the table top, in particular a fastening means with a fastening cross, fastening plate or the like, on which the table top rests, wherein said fastening means has a defined pattern of holes with a plurality of holes or mounts for fastening screws, which can be plugged through said holes in each case and by way of which the fastening means is screwed to the table top. According to the invention, the table top (10) has slots (11) or grooves which are made in its underside and run such that, when the table top is placed in position on the fastening means, in particular the fastening cross, they coincide with the holes (20) or mounts of the fastening means, in particular of the fastening cross (17), wherein fastening screws which can be screwed into the table top (10) in each case in the region of the slots (11) or grooves are provided.

A connecting device for interconnecting a vertical tube and a plurality of display cabinets for carrying display modules includes first and second connecting frames and a fastening unit. The first connecting frame is for mounting the display cabinets thereon, abuts against a front outer surface of the vertical tube facing the display cabinets. The second connecting frame abuts against a rear outer surface of the vertical tube facing away from the first connecting frame. The fastening unit includes first fastening sets fastening the first and second connecting frames together so as to clamp the vertical tube therebetween. The second fastening sets fasten securely the display cabinets to the first connecting frame.

The present invention provides a clip-shelf fixer, comprising a pipe clip with two side clip-claws on both sides, which a bayonet is formed between the ends of the two side clip-claws and a pipe cavity is formed between the two side clip-claws, wherein the two side clip-claws on both sides are provided with a first portion of the two side clip-claws and a second portion of the two side clip-claws along the axial direction of the pipe cavity; there is an gap between the first portion and the second portion of the two side clip-claws, which is compatible with mesh wires of mesh plate, and at the end of the gap a first mesh wire connection part perpendicular to the axial direction of the pipe cavity is provided; the first mesh wire connection part is provided with a first mesh wire cavity, and the first mesh wire cavity is connected with the pipe cavity to form an integral pipe and mesh wire connection cavity. The present invention can connect the supporting pipe with the mesh plate steel wire intersecting with it, and each supporting pipe can be connected with the matched mesh plate on the support pipe, so as to avoid missing connection; and the overall structure of the clip-shelf fixer can be further strengthened by combining with the parallel steel wire connection structure.

A modular chair assembly includes a seat member and at least three support leg units. The seat unit includes a seat member which has a lower surface and an upper surface opposite to the lower surface. Each of the three support leg units is detachably mounted to the lower surface of the seat member, and includes an inner axle and a hollow tube sleeved on the inner axle. The inner axle and the hollow tube are made of different materials to permit the inner axle to have a larger anti-bending strength than the hollow tube. The inner axle includes a bottom end surface for being supported on the ground.

A pedestal leg assembly includes a pedestal leg and floor base. The leg includes a plurality of teeth near the bottom end of the leg and a connecting bolt in a threaded engagement with the bottom end of the leg. The floor base includes a recessed portion having a slot in its bottom surface to receive the bolt and a release mechanism configured to pivot between a lock position and a release position. In lock position the release mechanism engages at least one of the teeth to prevent rotation of the pedestal leg in at least one direction. When pivoted into release position, the release mechanism is moved away from engagement with the teeth to allow rotation of the pedestal leg in both clockwise and counterclockwise directions. The pedestal leg assembly may include a powered connection to receive input power and/or a communication signal at the floor base and transfer the power and communication signals to a supported table top surface.

The patent application discloses a highly stable seat chassis.
