A mechanism is hereby disclosed that, when activated in the linear direction of its axis, will expand and contract radially. The novel nature of the device is that of compliant methods and materials used in its design. Compliant members, referred to as dyads, translate the motion and imply resistance in a single structure. Thus eliminating the need for separate members, hinges, pins, springs and the associated assembly. When these compliant dyads are combined in the novel configurations hereby disclosed, a device is created that expands (or contracts) in multiple directions from its primary axis of actuation. Furthermore, one or more actuation dyad sets could be arranged at various angles relative to the global vertical axis. The radial expansion/contraction can be 2D or 3D by adding more primary activation dyad sets. Such a device can be applied to many applications and industries. One such application is for gripping the inside of a tube or object for moving manually or in automation. The compliant nature of this device can be optimized to auto-adapt to the objects size and shape allowing for greater part variation and reduce manufacturing line change-over times. Other applications would include snap fit connections, spherical articulating joints, spinning cutting tools, speed limiting using friction and centrifugal force, braking rotational forces or transmitting it, automatic centering, expanding elastic bands in an assembly process, and stretching an opening for fitment. The design of this device is material friendly and can be made of plastic, composite and metals. It may be of a single monoform construction (created by molding, machining, or additive manufacturing) or made of multiple parts including pivots and different materials to achieve the desired articulation.

A tripod hose spray nozzle attachment for providing an elevated, aimable, water stream includes a tripod platform having a top side and a bottom side. The top side has a hose aperture extending through the bottom side. A plurality of legs is coupled to the bottom side and to form a tripod base. A hose fitting is coupled to the bottom side and is in fluid communication with the hose aperture. A flexible hose neck is coupled to the top side and is in fluid communication with the hose aperture. An adjustable spray nozzle has an attachment end coupled to a distal end of the flexible hose neck and a spray end having a plurality of apertures to release the water from the flexible hose neck. The spray end has an adjustment mechanism to alter the flow rate and concentration of the water.

An anti-debris device releasably engages and covers an unconnected end of a fluid-conveying quick disconnect connector to prevent debris intrusion. The device comprises a boot defining a cavity shaped to receive the connector, a connector-receiving access opening to the cavity, and a closure member such as flexible sheet slit to form resilient fingers movable between an opening-covering position preventing intrusion of foreign matter when the boot is not being used, but that flex to a connector-receiving position when an unconnected portion of a connector is biased against the closure member. The fingers assist in retaining the device on the connector. Various embodiments allow retaining the anti-debris device to a particular connector when the device is not in use, and/or for storing/protecting multiple connectors. Related methods are also disclosed and discussed.

An elongate profiled section element for a mounting system includes a bottom, a top side opposite the bottom, and sidewalls extending from the bottom to the top side. The top side includes two flanges which extend from the side walls and delimit between them a longitudinal slot. The top side has a smaller width than the bottom. At least one of the side walls is a stepped sidewall having a stepped shape seen in cross section. The stepped sidewall has two wall sections facing the opposite sidewall and an intermediate wall section substantially parallel to the bottom. The intermediate wall section is provided with a row of holes and the bottom is provided with a row of holes aligned therewith, said holes being adapted to cooperate with a self tapping screw.

A connection device for pipes including a first hose-holder (18) mounted on an end portion (3) of the pipe, a second hose holder (16) mounted on the other end portion (6) of the same pipe and a connection element (15) for the connection of the first and second hose-holders (18,16). The connection element (15) consists of a substantially tubular body having a longitudinal hole (30), and a circulating ball portion (17) for the connection to one of the first hose-holder (18) or the second hose-holder (16).

A gypsum slurry modifier device is provided for use with a gypsum mixer outlet boot having at least one tubular outlet leg, and includes a support bracket mountable to the outlet boot; at least one clamp member associated with the support bracket and constructed and arranged for engaging the at least one tubular outlet leg of the outlet boot. Each at least one clamp member is constructed and arranged for exerting a vertical compression force on the associated at least one tubular outlet leg for expanding a slurry outlet flow from the at least one leg laterally beyond an exterior surface of the leg.

A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.

A holder including a holding body configured for displaceable attachment to a rod and including a rod passage opening for the rod, and a clamping unit movable between a clamp position and an enable position. The clamping unit, in case of the holding body attached to the rod, in the enable position is capable of enabling a shifting movement of the holding body along the rod and in the clamp position is capable of exerting a clamping force to block a shifting movement of the holding body along the rod. An operating unit is provided for user-operated moving of the clamping unit between the clamp position and the enable position. The clamping unit is a wrap spring unit wrapping around the rod passage opening and comprising a plurality of wrap springs disposed adjacent to each other in a longitudinal axis direction of the rod passage opening, each spring wrapping around the rod passage opening over more than 180, and/or a wrap spring wrapping around the rod passage opening over more than 360, wherein the respective wrap spring is movable by the operating unit between a constricting condition providing the clamp position of the clamping unit and an enlarging condition providing the enable position of the clamping unit.

A portable hose carrier for RV sewer hoses is disclosed. The portable hose carrier has an outer tube, an inner tube within the outer tube, and a clamp encircling one end of the outer tube. When the clamp is open, the inner tube may telescopically slide within the outer tube. When closed, the clamp fastens the inner tube and outer tube together so long as some portion of the inner tube remains within the outer tube. A relief slot in the outer tube allows the outer tube's diameter and circumference to be reduced when the clamp is in the closed position. Each of the inner tube and outer tube has a respective endcap at opposing ends of the inner and outer tubes. At least two inner legs and two outer legs are rotatably attached to the end cap of the inner tube and outer tube, respectively.

The reel compatible multi-chuck air hose may allow a user to simultaneously inflate multiple tires while providing a lighter and easily stored form factor. The reel compatible multi-chuck air hose may provide four air chucks in series, as opposed to in parallel, with an air source connector at its first end, instead of in the middle of the line. Each of the four air chucks may be connected to the primary hose by a T-connector and may be stored within a dock to keep the air chuck in line with the primary hose. By this design the reel compatible multi-chuck air hose can be rolled around a storage reel for easy storage.
