A folding shelf includes a first sheet body and a second sheet body. The first sheet body has a first block, a second block, a third block, a fourth block, a fifth block and a sixth block. The first block is in a trapezoidal shape and the second block is in a trapezoidal shape and its upper bottom edge is connected to an upper bottom edge of the first block to define an engaged status. The third block is in a triangular shape and connected to one of the side edges of the first block, and the fourth block is in a triangular shape and connected to the other side edge of the first block and configured to be symmetrical to the second block. The fifth block is in a trapezoidal shape and its side edge is connected to one of the side edges of the second block, and the sixth block is in a trapezoidal shape and its side edge is connected to the other side edge of the second block and configured to be symmetrical to the fifth block. The arrangement of the first to sixth blocks allows the first sheet body to from a contour line of a rectangular sheet structure. The edges of the first to sixth blocks can be folded into a shelf. The second sheet body has an area smaller than the first sheet body, and a side of the first sheet body is partially disconnected from the first sheet body. Therefore, users can form the shelf by folding to facilitate the application of placing objects. When the shelf is not in use, the shelf can be maintained as a sheet body to facilitate storage and carrying.

The present invention relates generally to a repositionable and handheld easel of lightweight composition, and that is removably attachable to a painting canvas frame without interfering with any paintable portion of the canvas. The handheld easel is also adjustable in size to accommodate virtually any size of handheld canvas frame, and allows the painting surface to be rotated in relation to the artists hand to enable the artist to achieve a specific brush stroke while the handheld easel remains in the artist's hand.

An apparatus for mounting a device to a dashboard of a vehicle has a planar element having a first height, a first width, a front planar surface and a back planar surface, and a mounting element having a second height smaller than the first height, a second width smaller than the first width, and a length, the mounting element joined to the back planar surface of the planar element such that the length of the mounting element extends orthogonally to the back planar surface. The mounting element is adapted to fit into an existing opening in the dashboard of the vehicle, such that the planar element is supported and presented with the front planar surface upright.

An assembly can include a rectangular device that includes an x dimension, a y dimension and a display; and a stand that supports the rectangular device in different orientations, where the different orientations include a horizontal orientation of the x dimension and a horizontal orientation of the y dimension, where the stand includes an adjustable coupling that physically supports at least a portion of a mass of the rectangular device in the horizontal orientation of the x dimension and that physically supports at least a portion of a mass of the rectangular device in the horizontal orientation of the y dimension.

A defense mobile device for securing a door during shelter-in-place situations. The device includes wheels rendering it mobile and stops that, when actuated, hold the device stationary. A panel has a ballistic core that resists bullets, a front face, an opening, and a cover positioned over the opening to overlay and enclose a door knob protruding through the opening. The front face forms, or has affixed to it, a writing surface. The panel pivots between a plurality of angled positions to facilitate writing and an upright position flat against the door. A locking rod, rotatably connected to the panel, pushes and pulls the panel between its angled positions and its upright position. A lever-locking mechanism or a twist-lock mechanism secures the device in place against or within a door frame and against the door.

A portable easel includes a base component having an upper surface, a lower surface, a continuous periphery and a central aperture. On the upper surface are a plurality of canvas grooves, each having a differing or discrete width and/or depth for receiving an edge of a canvas. The upper surface also includes one or more arcuate notches for retaining artist's tools, such as paint brushes, painting and palette knives, scrapers, etc. Narrow slits are variably positioned on the upper surface to receive and uprightly support canvas boards or similar thinner media. The lower surface of the easel includes a locking means for mating with canvas grooves on another easel to allow multiple easels to be compactly and seamlessly stacked for storage.
