Apparatus and associated methods relate to a ratchet strap system configured with a ball-shaped handgrip adapted to manipulate a ratchet strap drive shaft. In an illustrative example, the handgrip may include a substantially spherical distal portion coupled to the drive shaft via a substantially cylindrical neck member. The handgrip may, for example, be configured for after-market installation by receiving a shaft extension member of the drive shaft. Some handgrips may include opposing radial apertures for a retention pin to longitudinally fix the handgrip to the shaft extension member. A pliable resilient member disposed at the distal end may prevent decoupling prior to tensioning the strap. In various embodiments, the deployment time of a ratchet strap system may, for example, be reduced by using the handgrip to facilitate initial winding of a load securing strap, and to wind excess strap length for storage in conjunction with an elastic retaining loop.

A clip assembly may safely secure sliding sashes of a window or door during transportation, and, in one embodiment, be comprised of a strap member and a pawl member. The strap member may be comprised of a bumper portion, and a strap portion extending therefrom, where the strap portion may have a plurality of teeth formed within the thickness of the strap. The pawl member may have a pair of sidewalls supported by a top wall and an intermediate wall. The top wall may have a protrusion which includes a plurality of pawl teeth formed to complement the strap teeth, and be located proximate to the intermediate wall. The strap may be introduced through the gap between the top rail of an upper sash and bottom rail of the second sash, to then be inserted into the pawl, and thereby be retained by the respective teeth to secure the sashes.

Rack systems are disclosed for coupling accessories to crossbars on top of a vehicle. A coupling device may include a flexible strap member adjustably anchored at one end of a body. The strap member may be connected to the other end of the body and tightened. A mounting assembly may be provided on the top side of the body for connection to a cargo-specific carrier or accessory. A coupling device may also include a flexible fitting member configured to grip a round or rectangular crossbar. A cap member may be configured to be mounted on the fitting member and have one or more ramp surfaces which form a sliding interface with a corresponding surface on the fitting member, thereby providing a closing or tightening effect on the fitting member with respect to the crossbar. Other coupling devices are configured to grip or clamp a t-slot in the crossbar.

Disclosed is a thin-film radio frequency absorber material that is mass-produced by a high-speed manufacturing method of printing a highly controlled pattern of conductive ink squares onto a thin roll film, resulting in a lightweight low-cost radio frequency absorber component that is flexible for use in multiple novel configurations. The roll film material and printed squares are each easily adjustable to a specific size and thickness within the manufacturing process to coincide with control and protections related to variable specific radio and radar wave frequencies. Further integration into the three-layered thin-profile radio frequency energy absorber and reflector assembly provides control and protection properties related to radio and radar frequency, infrared, electromagnetic pulse, electromagnetic interference, and thermal insulation values in structural building panels utilized in lightweight structures such as the foldable transportable structure or other types of building and protection assemblies.

An anti-slip safety tensioning device for automobile, comprises a driving handle assembly, an eccentric shaft, a support assembly, a long band and a short band; wherein, the driving handle assembly is located between a pair of support lateral plates of the support assembly, and can be rotatable relative to the eccentric shaft; and when the driving handle assembly is folded, the eccentric shaft is located on a rear side of the top shaft and the eccentric bulge of the eccentric shaft faces the top shaft; the long band having a free end wrapped around the eccentric shaft, and the free end passes through the gap between the eccentric shaft and the top shaft. When in unfolded state, there is a largest gap between the top shaft and the eccentric shaft.

An apparatus used for winding or unwinding winch straps includes a clevis, a first engagement plate, and a second engagement plate. Both the first engagement plate and the second engagement plate contain a lobe, a lug, an oblong body, and a plate pinhole which are rotatably connected to the clevis with a plate retaining pin which traverses through the plate pinhole. When in use, a power tool is attached to a tool-receiving slot, which is integrated into a structural body of the clevis. Next, the lobe of the first engagement plate and the second engagement plate establishes a connection with the spool hub the apparatus is being used on. Simultaneously, the lug of the first engagement plate and the second engagement plate are pressed against the spool hub. Therefore, the force is transferred from the power tool to the spool via the introduced apparatus.

A strap coiling device includes a housing, a spindle rotatably coupled within the housing, a return spring assembly operatively connected to the spindle within the housing, and a stator releasably engaged with the spindle, wherein a free end of a length of strap is coupled to the spindle and automatically wound around the spindle within the housing in response to disengagement of the spindle from a stator to allow rotation of the spindle caused by the return spring assembly.
