Anchoring element for hanging and connecting objects on pre-walls and/or metal surfaces, without the need for tools, including: a front face with a broadly flat geometry intended to rest opposite the wall plane a back face provided with coupling elements, for coupling the anchoring element to a fixing element and/or a hole configured to contain a magnetic element and projections located in recesses arranged on the periphery of the back face, in such a way that the anchoring element can receive support elements, both in the direction from the X and Y axes of the wall plane.

A tonneau cover and a method of attachment are disclosed herein. In some embodiments, a self-energizing clamp can be used to retain a tonneau cover onto a side wall of a truck bed, or other vehicle bed. In some embodiments, the clamp can be rotated between a usage position and a storage position in order to prevent the clamp from incidental movement or harm while accessing the truck bed.

Provided is a device for changing a frame angle of a foldable article. The device combines frames using a connecting and assembling member and an elastic string and makes up a leg or a support frame of the foldable article. The connecting and assembling member with which a first end of the elastic string is combined and which has multiple combination grooves in such a manner that the frame combined with a second end of the elastic string is selectively combined with the connecting and assembling member. The first end of elastic string is combined with the connecting and assembling member, and the second end of the elastic string is combined with the frame such that the frame can be elastically operated. The frame is combined with the first end of the elastic string and is elastically insertable into or separable from the connecting and assembling member.

Systems, apparatuses, and methods for constructing an airship quickly and cost-effectively are described. In one embodiments, a jig for constructing a mainframe of an airship structure may have a first rail and a second rail that are configured to be parallel to each other, the first rail and the second rail each forming an arc, multiple first supporting structures coupled to the first rail, wherein the first supporting structures have non-uniform heights to support a curvature of the arc of the first rail, multiple second supporting structures coupled to the second rail, wherein the second supporting structures have non-uniform heights to support a curvature of the arc of the second rail, wherein the first rail and the second rail are configured to interface with detachable wheels coupled to an outer surface of the mainframe and enable the mainframe to be rotated along its axis on the jig

An adjustable bathroom handrail assembly is provided with a pair of elongate vertical handles with mounting hardware to mount to an upright support surface and spaced apart from the upright support surface. An adjustable horizontal bar extends between the pair of vertical handles, and a locking mechanism connects the at least one adjustable horizontal bar and one of the pair of elongate vertical handles. A locking mechanism is located at an intersection of the horizontal bar and the one of the elongate vertical handles. A method for installing and adjusting wall-mount hardware installs a pair of elongate vertical handles to an upright support surface. The ends of a horizontal bar are installed onto the pair of elongate vertical handles. A locking mechanism on the horizontal bar is disengaged to adjust the horizontal bar to a location along the pair of elongate vertical handles.

The present invention provides modular frame assembly including a plurality of connecting pieces. The connecting pieces can include a first plurality of coupling connectors, a second plurality of tee connectors, a third plurality of corner connectors, and a fourth plurality of elongate members. Each of the plurality of connecting pieces is adapted to receive at least two elongate members such that a rectangular structure can be constructed from the plurality of connecting pieces.

Systems, apparatuses, and methods for constructing an airship quickly and cost-effectively are described. In one embodiments, an airship structure may have a plurality of mainframes, each comprising interconnected pyramid structures. One of the pyramid structures may include an apex joint, four base joints, first connectors, and second connectors. The apex joint and base joints may each have slots configured for receiving connectors. The apex joint may have four apex-to-base slots and each base joint may have a base-to-apex slot and two base-to-base slots. Each of the first connectors may connect the apex joint to one of the four base joints using one of the apex-to-base slots of the apex joint and the base-to-apex slot of that base joint. Each of the second connectors may connect two of the four base joints using one of the base-to-base slots of each of the two base joints connected by that second connector.

The invention provides a reusable linkage which has a coupling which coupling has one or more male connectors formed from two or more compressible leaves; and/or one or more female connectors wherein each female connector is shaped to receive a male connector; wherein the compressible leaves of the male connector are shaped to resiliently engage the female connector and wherein the leaves of the male connector are compressible such that a male connector can be removed from a female connector.

A mounting device includes a first male threaded fastening member such as a lag screw and a second male threaded fastening member such as a bolt. The male threaded fastening members are secured to one another through a joining member such as a bolt and female threaded fastening members such as wingnuts or star knobs. Tightening the female threaded fastening members fixes an angle between the male threaded fastening members without the use of tools. The first male threaded fastening member typically mounts to a tree, a post, or the ground and the second male threaded fastening member typically mounts to a camera or other electronic device. Adapters can secure the mounting device to steel fence posts or step-in posts. An internal spacing device with a flange prevents wear and tear of components of the mounting device.
