In a snap-fit for attaching a second unit to a first unit, an engaging member provided on the second unit includes: a claw configured to restrict movement of the second unit relative the first unit in a removing direction; an elastic support configured to support the claw so as to be movable in a direction intersecting the removing direction and in a releasing direction in which the claw is released from the engagement with an engaged member provided on the first unit; and an operative part provided on the elastic support and configured to release an engagement of the engaging member with the engaged member. The operative part includes at least a portion that overlaps the claw with respect to the removing direction.

Disclosed are systems and methods for coupling a first panel to a second panel via a push retainer. The push retainer includes an annular body, flexible tabs, and legs. The annular body has a topside surface and an underside surface. The annular body defines an opening. The flexible tabs are coupled to the annular body and canted upwardly away from the topside surface at a first angle. The flexible tabs are configured to engage a post of the second panel. The legs extend downwardly away from the underside surface at a second angle. The legs are configured to engage the first panel to form a part-in-assembly (PIA) component when inserted through the opening.

The apparatus for fastening a vehicle component in and/or on a vehicle has a sound insulation element with a carrier layer and a sound absorbing layer. An anchoring recess is formed in the carrier layer and has an insertion opening in a first side of the carrier layer, which insertion opening is adjoined by a receiving space which is delimited by the plastic material of the carrier layer and is defined by a closed circumferential inner side and a closed bottom surface. An anchoring element is further provided. The anchoring recess has a constriction area formed on the circumferential inner side and at least partially narrowing the receiving space, with a widened widening area adjoining in the direction of the bottom surface. The anchoring element has an anchoring shoulder for engaging behind the constriction area when the anchoring element is received by the anchoring recess.

An apparatus for connecting a first component to a second component by a ball which is fastened to the first component and which is fastenable in an opening of the second component includes a tool which includes two gripping elements and a retainer. The ball can be encompassed and pulled into the opening in a fastening direction by the two gripping elements. The second component is holdable in a position relative to the tool along the fastening direction by the retainer. The two gripping elements are movable relative to the retainer along the fastening direction to pull the ball into the opening until the first and second components are in contact with one another. The tool is movable in three dimensions by a robot.

Systems, methods, and articles of manufacture for modular junction boxes. Some modular junction boxes may, for example, comprise integral mating elements that are secured in position by mounting of one or more adapters, connectors, or fittings.

A fence support system has a catch member comprising a catch plate and a protrusion that extends from the catch plate and a retainer member comprising a retainer plate comprising an aperture, the aperture being configured to receive the protrusion in response to relative movement of at least one of the catch member and the retainer member along an insertion path. When the protrusion is received by the aperture, a curved base portion of the protrusion that does not extend through the aperture is located, as determined along the insertion path, between the catch plate and the retainer plate. The curved base portion is curved angularly about the insertion path.

Disclosed are systems and methods for coupling a first component to a second component via an integrated fastener. The component assembly comprising a first component having a first surface and a second surface. An integrated fastener extending from the second surface and configured to attach the first component adjacent to the second component. The wherein the first component and the integrated fastener are formed as a unitary structure using, for example, an additive manufacturing process. The integrated fastener can comprise a clip assembly with one or more retention features extending outwardly from the integrated fastener at an end opposite the first component.

An anchor for connecting a concrete layer of a floor to a cellulosic layer of the floor, the cellulosic layer comprising a plurality of cellulosic members joined together in a side-by-side arrangement, the anchor including a first portion to extend between two adjacent cellulosic members of the cellulosic layer into the concrete layer of the floor. The first portion includes attachment structure to attach the first portion to one of the two adjacent cellulosic members of the cellulosic layer to attach the anchor to the cellulosic layer. An upper edge margin of the first portion is disposed within the concrete layer when the first portion is attached to the cellulosic layer. A second portion extends from the upper edge margin in a first direction that is transverse to the first portion. The second portion is spaced apart from the cellulosic layer and embedded within the concrete layer of the floor to attach the anchor to the concrete layer.

A connector assembly may include a body including a first aperture and a second aperture; a rotating member disposed at least partially in the first aperture; and/or a mating member having a portion disposed at least partially in the second aperture. The rotating member may be configured to rotate to limit movement of the mating member.

In an example, a clamp assembly for a glass on glass solar module for a tracker is included. The assembly has a lower clamp structure characterized by a top-hat shaped rail structure having a length extending from a first end to a second end. In an example, the assembly has an upper clamp structure configured to sandwich a pair of edges of a pair of solar modules with a portion of the lower clamp structure. In an example, the assembly has a locking spacer configured to the pair of edges of the pair of solar modules. In an example, the pair of edges comprises substantially glass material. In an example, the assembly has a pair of key structures configured with the locking spacer. Each of the key structures is affixed to each of the solar modules to physically lock each of the solar modules to the upper clamp structure.
