A ligature-resistant bag hanger for supporting an intravenous (IV) bag prevents formation of ligatures over an IV pole and on the bag support hooks. Internal components of the ligature-resistant IV bag hanger are enclosed in a housing. The internal components of the ligature-resistant bag hanger include one or more bag support hooks that have an extension portion extending from an interior of the housing and that are rotatable around an axle located within the housing. In a reset position, the bag support hook(s) support(s) an intravenous bag in a saddle portion of the hook up to a threshold weight limit. In a triggered position, initiated by a downward force in excess of the threshold weight limit rotating the hook downward, the hook rotates so that an attempted ligature formed above the saddle portion of the hook is released by retraction of the saddle portion of the within the housing.

The invention is directed to a construction tube which has a circular cross section, wherein the circular cross section including two circular stretches and two flat stretches diametrically opposite from each other which define two parallel planes interrupting the circular stretches. It enables the advantages of construction tubes with a circular cross section and the advantages of tubes with a polygonal cross section to be combined. The construction tube can be joined to a connectable element, which is preferably selected from another construction tube and an output shaft of a reducer of a solar tracker, in particular, using inner parts and/or clamps. The construction tube of the invention has a special application in solar collection systems, making up a torsion shaft of a solar tracker.

A rod connector is provided including a disc portion, a first shaft portion and a second shaft portion. The disc portion has a first side configured to engage a first rod and a second side configured to engage a second rod. The first shaft portion extends from the first side of the disc portion and includes threads along at least a portion of the length thereof for engaging threads of the first rod to draw the first rod into engagement with the disc portion. The second shaft portion extends from the second side of the disc portion and includes threads along at least a portion of the length thereof for engaging threads of the second rod to draw the second rod into engagement with the disc portion.

Disclosed herein attachment mechanisms and methods of using the same. The attachment mechanism includes a first connector, a second connector, and a coupling positioned between and coupled to each of the first and second connectors. The first connector is adapted to be mounted to a stable or unstable base. The second connector is adapted to be mounted to a body-secured or gripped object. The coupling is adapted for free 360° rotation relative to at least one of the first and second connectors without decoupling therefrom. A method of using an attachment mechanism includes mounting a coupling to a first connector and mounting the coupling to a second connector opposite the first connector. The coupling is adapted for free 360° rotation relative to at least one of the first and second connectors without decoupling therefrom.

A connector (10) for jointing bars is provided. It comprises a shank (13) for attaching to a first bar, a connection head (14) jointed to the shank (13). The connection head (14) comprises a projecting post (22) and a well (24), which are in alignment with the longitudinal axis (17) of the shank (13). The size and shape of the well (24) correspond to the size and shape of the projecting post (22). An identical connector is provided for attaching a second bar.

Disclosed is a filler piece mounting assembly for a lifting column. The lifting column includes a first casing and a second casing sliding in the first casing. The filler piece mounting assembly includes a resilient filler piece and a fixed frame for fixing the resilient filler piece. The resilient filler piece is disposed outside an outer wall of the second casing and axially fixed relative to the first casing. The fixed frame is disposed at a front end of the first casing and moves relative to the first casing. A first inclined surface is disposed on an outside of the resilient filler piece. The fixed frame includes an extrusion part for extruding the first inclined surface, and the extrusion part extrudes the first inclined surface to radially deform the resilient filler piece to adjust a clearance between the resilient filler piece and the second casing.

Turnbuckle linkages are disclosed herein. A turnbuckle linkage includes an inside rod including a first opening on a first longitudinal end and a second opening on a second longitudinal end of the inside rod, the first opening and the second opening extending at least partially through the inside rod, the inside rod including tabs extending from the first longitudinal end and the second longitudinal end of the inside rod around the first opening and the second opening, an exterior surface of the tabs including conical threads, outside rods to be positioned within the openings of the inside rod, the tabs of the inside rod at least partially surrounding the outside rods, the outside rods including end bearings to couple to a first structure and a second structure, and conical nuts to constrict the tabs around the outside rods and couple the inside rod and the outside rods.

The present invention provides an improved locking mechanism for securely connecting modular or detachable components. The locking mechanism includes a male and female portion associated with, respectively, a first and second modular component, the male portion having a slit defining a first and second finger, the locking mechanism having a spreading means provided by a pressure bolt mechanism including a pressure bolt, wherein the pressure bolt is configured to, when turned by up to substantially 1 revolution, move the first and second fingers from a closed position wherein the first and second fingers are substantially parallel to one another, to a spread position wherein the first and second fingers abut an interior surface of the female portion, thereby connecting the first and second modular component.

An improved animal structure is disclosed. The structure includes various features which can improve transportation, ease of assembly, structural integrity, and/or aesthetic quality. The animal structure includes a post having multiple post sections, namely a first post section and a second post section. The first and section post sections are coupled to together by a post coupler wherein the post coupler is disposed completely within a hollow interior of the post when the first post section is flush with the second post section.

A frame includes a plurality of profile sections and at least one first adapter assembly. Each profile section includes at least one section extension surface, and one of the at least one section extension surface is provided with at least one first groove therein. Each first adapter assembly includes a first position-limiting block provided with at least one first mounting hole therein. The first position-limiting block is configured to be fixed in a first groove during assembly, and to fix other components to the profile section through the at least one first mounting hole.
