A foldable tail assembly for an aircraft includes a stabilizer and a pair of right and left fins mounted with respect to the stabilizer so that the fins may lay flat over the stabilizer during periods when the aircraft is not flight-ready, and so that the fins may be erected above the stabilizer to form a triangular configuration when the aircraft is ready to fly.

The invention relates to a super hoisting device for hoisting equipment, which comprises at least one super hoisting bracket (2), a first tensioning mechanism (1) and a second tensioning mechanism (3). The fixed end of the super hoisting bracket (2) is articulated with a hoisting boom (6) of the hoisting equipment; one end of the first tensioning mechanism (1) is connected to the movable end of the super hoisting bracket (2) and the other end is fixed to the head end of the hoisting boom (6); one end of the second tensioning mechanism is connected to the movable end of the super hoisting bracket (2) and the other end is connected to a turntable (4) of the hoisting equipment. In addition, the invention also relates to telescopic-boom hoisting equipment provided with the super hoisting device.

A shelving unit includes formed front and rear beams providing shelf supporting and lower flanges, respectively. A C-shaped tie bar extends centrally between respective front and rear beams and is captured between the beam flanges with tie bar ends engaging the beams providing loaded shelf support and resisting loaded beam twisting.

A container assembly for bulk materials and a kit for assembling same are disclosed. A forming member having a plurality of sidewalls defines an internal cavity for receiving bulk materials. The sidewalls are arranged relative to one another and are locked into position so as to define a geometric volume of predetermined shape, by means of a locking assembly. The locking assembly can be integrally attached to or can be separable from the sidewalls, and can form a bottom of the container assembly. A tubular sleeve of continuous material is sized to snugly engage and overlie substantially the entire outer surface area of the sidewalls. The sleeve provides the containment strength, while the forming member provides structural shape and stability to the container assembly. Additional layers of corrugated material or woven polypropylene material or their combination may be used as inserts engaging the inner peripheral sidewall areas of the forming member to provide additional strength to the container assembly. The forming member sidewalls may be freely slidable relative to one another or may be slidably affixed to one another by releasable glue.

A rod-type connecting profiled element (10) for connecting sheet piles to carrier elements comprises a central strip (12) that separates two opposing connecting profiled elements (16, 18), each of which respectively forms a saw (24, 42). One connecting profiled element is embodied as a plug-in profiled element (16) for the carrier element and the other connecting profiled element is embodied as a receiving profiled element (18) for connecting a sheet pile. The central strip (12) comprises, on the side of the receiving profiled element (18), a central section (14) having a straight plane inner wall (30) to which a first short end section (32) is connected on one side, said short end section protruding past the central section (14) at an angle of approximately 90°, and being connected thereto by means of a transition section (36) having an inner wall with a cross-section that follows a quadrant. A hook strip (34) is arranged on the other side of the plane central section (14) as a second end section oriented in the same direction as the first end section (32).

A hinge for wings such as ironing board supports the board off a support (3) on pairs of link (2, 3) which engage (29, 30) to limit angular movement beyond a working disposition. The board (24) may be folded and collapsed into a wall mounted cover (28). The wall mounted unit might be fitted to a height adjustment mechanism (118). The links (2, 3) may be combined with a means (63) increasing the angular extent of the folding action to collapse the folded board (80) into a drawer unit (84). The board may be mounted to a turntable (101) to allow for angular movement. The board (24) may be supported on supports (35) attached to sliding tracks (34) to enable movement to a storage position in a cabinet (32).

A stool includes a collapsible frame, a triangular seat and a back. The frame includes a bottom hub with three telescopingly adjustable legs and enlarged feet. A top hub is rotatably coupled to the bottom hub for 360 degree rotation, and includes three seat-supporting arms that extend from the top hub, and a pair of uprights that extend from two of the arms. The seat hook-attaches to loops on ends of the arms, and the back extends between the uprights. The legs and arms are pivoted to their respective hubs, but the pivots are slightly frictional so that the arms and legs remain in adjusted positions, with stops on the hubs stopping the legs and arms in their upwardly-pivoted use positions. The frictional pivots include lubricious plastic that facilitates quiet unfolding of the stool, which is important when hunting.

A base is provided for use with warning signs and the like. A metal structural framework is fitted to the underside of an elastomeric body in the form of a monolithic slab. Forces from the sign panel are transmitted through the structural framework, which includes a plurality of outwardly radiating legs. Forces are transmitted to the ends of the legs, which preferably are fitted with outwardly extending feet. Force loadings are transmitted through the structural framework rather than the elastomeric body, which provide a ballast for the structural framework.

An apparatus for drying scuba diving gear is provided having a support member and first, second and third hanger sub-assemblies removably, slidably engageable with respect to the support member. The sub-assemblies are in vertical alignment with one another at their point of engagement with the support member. Each sub-assembly is adapted for specific pieces of scuba gear. Preferably, the support member is a vertically disposed shaft telescopically secured to an erectable / collapsible tripod assembly. An apparatus is also disclosed where the support member is a chain assembly having an attachment hook for attachment with respect to an overhead support at one end and a support bar to hold the hanger sub-assemblies upright in engagement with the chain assembly at the other end.
