A tolerance compensation element that compensates for tolerances in the distance between first and second components, includes a thread bolt having a first drive feature, a first thread of a first thread direction and a second thread of a second thread direction. Between the first and the second thread, a protrusion extends from the thread bolt radially to the outside. The element includes a first plastic overmold in the portion of the first thread, which provides a fastening structure for the fastening to the first component, and a second plastic overmold around the protrusion which extends radially to the outside, to provide an abutment portion abutting the second component when in use. A distance of the second plastic overmold to the first plastic overmold is changeable after overcoming a start-up torque between the first plastic overmold and the first thread in longitudinal direction of the thread bolt.

A coupling element for a positioning device, which includes a first and second linear guides for guiding first and second carriages respectively along first and second linear directions, is configured to create a coupling between the first carriage and the second linear guide. The coupling element includes a central part and a surrounding part spaced at a distance therefrom. The surrounding part has a central portion surrounding the central part, and has two end portions adjoining the central portion in the first linear direction. Connecting flat springs are disposed to create the distance and connect together the central part and the central portion of the surrounding part. The connecting flat springs lie in planes which intersect at a center of the central part. A vertical flat spring is disposed parallel to the first linear direction at each of the two end portions of the surrounding part.

A stacked oven may include a supporter installed between a first oven at a lower portion of the first oven and a second oven above the first oven and fixing the second oven at a position spaced apart upward from the first oven. The supporter may include a first installation member that includes a vertical extending member that contacts a side surface of the first oven, a lateral extending member that extends from an upper portion of the vertical extending member in a direction toward a center of the first oven, and a load support provided between a lower portion of the lateral extending member and the first oven; a second installation member that includes a lower surface support and a side surface support that contact a lower surface and a side surface of the second oven, respectively, and having an angle with respect to each other, and a guide that extends upward and outward from an upper end of the side surface support; and a connection member that vertically connects the lateral extending member and the lower surface support.

In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by placing it over various embodiments of a cone element that is embedded within the flashing and secured using a tightening mechanism such as a bolt, screw, or other fastener. A solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. Various embodiments of the bracket and flashing provided as well.

A connector may couple to a non-cylindrical composite tubing having at least two lateral sides disposed in parallel and an open end. The connector may comprise first and second bonding plates adhered to an inner surface of the two lateral sides via an epoxy adhesive uniformly distributed. The first and second bonding plates may each have a distal lateral face defining a plurality of first threaded holes accessible at the open end of the composite tubing. The connector may also comprise an end plate having a plurality of first and second slotted holes disposed substantially in parallel and each aligned with an associating one of the first threaded holes. The connector may also comprise end plate fasteners loosely inserted through the first and second slotted holes and engaged with the first threaded holes. The end plate may also comprise one or more attachment points.

A fastener includes a base member; a first member, on the base member and having a through bore; a second member, on the base member and spaced from the first member to form a receiving portion to receive a panel structure, including an aperture defining an internal surface, the internal surface including at least one stop member protruding radially inwardly, and a nut member, coaxially aligned within and frangibly connected to the internal surface, including at least one block member protruding radially outward from an outer surface of the nut member to stoppingly engage with the at least one stop member. During use, the nut member moves from a first position, where the nut is frangibly connected to the internal surface, to a second position, where the least one block member abuttingly engages with the at last one stop member.

A substrate usable with a double-side adhesive strip to suspend the substrate to a wall surface. The substrate can have one or more access holes located within an outer perimeter of the substrate. Each access hole has an inner perimeter inwardly of the outer perimeter that is sized and shaped to allow a tab of the double-sided adhesive strip to be extracted through the inner perimeter, after the substrate is suspended on the wall surface. Various articles can attach to the suspended substrate, such as through magnetic attachment, a hook, or a shelf.

In one embodiment, a fastener includes a flexible head and a shank coupled to the flexible head. The flexible head includes a center head portion and a plurality of wing portions coupled to the center head portion. Each of the plurality of wing portions includes a contact area configured to contact a first surface of a part to be fastened. The shank includes a clip groove configured to hold a retainer clip against a second surface of the part to be fastened. The second first surface of the part to be fastened is opposite the first surface of the part to be fastened.
