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.

There is provided a multi-leg stand, for photography and the like comprising a vertical main tube, a supporting structure for the vertical main tube comprising a plurality of legs connected to the bottom portion of said vertical main tube and including a plurality of lockable collars rotatably secured around the outer circumference of the vertical main tube and a leg rigidly secured to each of the lockable collars; each leg extends horizontally outwardly from one of the collars and including an outer end portion extending downwardly. At least one of the downwardly extending end portions, comprises a secondary tubular member having an opening at each end designed to securely hold a replaceable member; the replaceable member extends downwardly from the lower end opening thus providing further support for the stand. The stand can thus support either multiple lights or a combination of lights and reflectors or other elements.

A connector joint device for connecting rods or arms at a joint or intersection. The connector joint includes more than one hexagon shape faces, more than one octagon shape faces, more than one 4-sided polygon shape faces. A first face among the more than one octagon shape faces has a hole extending in a direction at an angle with respect to a perpendicular line to the first face.

A joint assembly for a bracket pool. The joint assembly includes at least one receiving channel for receiving a supporting tube of the bracket pool. The joint assembly also includes an installation portion defining at least one coupling region. A detachable storage tray including a containing portion for storing objects and at least one connector is removably coupled to the at least one coupling region of the installation portion for removably connecting the detachable storage tray the installation portion. The detachable storage tray is very convenient to install and disassemble, very stable in use, does not occupy extra space, and has low economic costs and manufacturing time and costs.

A connector assembly is used to attach the end of a horizontal rail to the supporting vertical post of a barrier. A flat platform is secured to the side wall of the post. A channel-shaped bracket having a convex base is seated within a concavity formed in the platform. A convex retainer is seated within the concave base of the bracket channel. A bolt extends through aligned openings formed in each of the platform, bracket and retainer. The bolt also extends through aligned openings in the post. The end of a rail is installed within the bracket channel, and held in place by a bolt. An elongate opening formed in the bracket base allows the bracket to swivel horizontally to a desired angular position. The bracket permits a single post to support adjacent sections of a barrier that intersect at a non-straight angle.

The invention relates to a locking device designed to lock objects to tubes or other elongated elements. The locking device generally comprises one or more lock plates and lock housings. In one exemplary embodiment, when assembling the locking device to a tube, two lock housings are put together with open sides against each other around a tube with a dimension corresponding to approximately half of a recess which is found on the lock housing's sides and are oriented in the tube's axial direction. The two lock housings form a closed geometry around the tube. Lock plates are used to connect the two lock housings together. By applying a screw in a threaded hole in one of the lock housings' cover, the through tube is pressed against an opposite lock housing at substantially the same time as the lock plates hold the lock housings together.

The support device for a rotating shaft of a solar tracker comprises a support plate (2) fixed to an upper end of a support column (1), and a clamp (3) comprising a lower clamp section (4) with a foot (7) fixed to the support plate (2) by means of screws (43) and an arcuate seat (9) for a bearing (52), and first and second opposite side clamp sections (5, 6) having upper ends at which there are arranged respective connecting elements (10, 11) connectable in an articulated manner to one another and lower ends at which there are arranged respective fixing and clamping elements (12, 13) configured for fitting onto the foot (7) and for being tightened against one another and against the lower clamp section (4) by means of a tightening screw (14).

A keyed interlocking support stand including a pair of support members; a pair of annular clamps coupled one each to the support members, each annular clamp positionably adjustable in relation to a support member length; a pair of keyed socket elements disposed one each within the annular clamps, each keyed socket element defining a keyed socket; a transverse member; and a pair of keyed posts coupled one each to opposing transverse member ends; whereby each keyed socket is configured to insertingly receive one of the keyed posts to interlock the transverse member between the support members.

A joint for a composite frame includes a first composite rod, a first shell abutting the first composite rod, a second shell abutting the first composite rod and disposed opposite the first shell relative to the first composite rod. The first and second shells are joined together such that composite rod is fixed therebetween. A method of forming joints of composite frame includes forming a composite frame by interconnecting a plurality of composite rods formed by an Automated Fiber Placement (AFP) manufacturing method around a mandrel, applying a first shell to the plurality of composite rods at a first location where composite rods are interconnected, applying a second shell at the first location opposite the first shell relative to the composite rods, and joining the first and second shells together with the composite rods at the first location disposed between the first and second shells.
