A press-in retainer is configured to join a surface element to a support structure that has an acceptance opening. The press-in retainer includes a retainer head including a collar, a platform, and a neck disposed between the collar and the platform. The retainer head is configured for placement into a channel defined by the surface element. A seal is disposed about a perimeter of the collar and includes a main body and a sealing foot. The sealing foot is connected to the main body by a living hinge extending along a perimeter of the main body and is disposed entirely outboard from the collar. A clip portion extends from the collar of the retainer head. The clip portion is configured for insertion into the acceptance opening of the support structure and includes two or more wing elements.

A bracket for securing a panel is provided, the bracket including a panel contact member including an interface portion. Also provided are a first clamp member having a first clamp surface contact portion and a first clamp adjustable portion operable to interface with the panel contact member interface portion and a second clamp member having a second clamp surface contact portion positioned such that it is facing toward the first clamp surface contact portion of the first clamp when the first clamp adjustable portion is interfacing with the panel contact member interface portion, such that the first and second clamp surface contact portions are facing inward towards each other. A securing member is operable to secure the first clamp member to the panel contact member, the securing member positioned substantially perpendicular to the first and second clamp surface contact portions.

Resilient mounting clips, panel mount systems including the same, and associated methods. A resilient mounting clip includes a support structure engagement portion and a panel engagement portion with a plurality of edge extensions and a plurality of outboard panel supports. Each outboard panel support extends from a respective edge extension. Each outboard panel support is configured to move at least substantially parallel to a compression axis when the respective edge extension resiliently flexes with respect to the support structure engagement portion. A panel mount system includes at least one support structure, at least one resilient mounting clip, and at least two panels received by each mounting clip. A method of assembling a panel mount system includes positioning and securing a resilient mounting clip on a support structure and receiving each of a first panel and a second panel with the resilient mounting clip.

Locking mechanisms and separable, repairable (e.g., electronic) devices having locking mechanisms are described herein. In one example, a locking mechanism includes a chassis having a base, a first side wall extending from a surface of the base, and a second side wall extending from the surface of the base. A cavity is provided in a volume formed by the first side wall, the second side wall, and the surface of the base, wherein the cavity is configured to receive a mating component of the device. The locking mechanism also includes a cantilevered plate having a first end and a second, opposite end, wherein the cantilevered plate is attached to the first side wall of the chassis at or adjacent to the first end, and wherein the second end of the cantilevered plate is positioned with the cavity.

A connection assembly for prefabricated components provided herein includes two C-shaped groove members and an H-shaped connection member. The C-shaped groove members are each provided with a component connecting part for fixedly connecting with a component, the H-shaped connection member includes a middle web and two side flanges, notches of the C-shaped groove members are in clearance fit with the web, and the side flanges are in stop fit with inverted edges of the C-shaped groove members when the H-shaped connection member is inserted between the C-shaped groove members. The C-shaped groove members and/or the H-shaped connection member are each provided with wedge members, and the wedge members have wedge surfaces for guiding the two C-shaped groove members to be fastened oppositely. The integrated H-shaped connection member replaces multiple bolts to meet the requirements of high-strength connection, which simplifies the operation and improves the construction efficiency.

Resilient mounting clips, panel mount systems including the same, and associated methods. A resilient mounting clip includes a support structure engagement portion and a panel engagement portion with a plurality of edge extensions and a plurality of outboard panel supports. Each outboard panel support extends from a respective edge extension. Each outboard panel support is configured to move at least substantially parallel to a compression axis when the respective edge extension resiliently flexes with respect to the support structure engagement portion. A panel mount system includes at least one support structure, at least one resilient mounting clip, and at least two panels received by each mounting clip. A method of assembling a panel mount system includes positioning and securing a resilient mounting clip on a support structure and receiving each of a first panel and a second panel with the resilient mounting clip.

Disclosed is a clip for fastening a first element to a second element, the clip having a head and a tip and a first side and a second side, wherein the first side extends from the head toward the tip and the second side extends from the head toward the tip. A first sidewall extends from the first side toward the second side and a second sidewall extends from the second side toward the first side, the clip having a latching projection projecting in a latching direction and having a latching face facing the latching direction. The latching face is arranged in a plane which is not parallel to the first sidewall and/or not parallel to the second sidewall. The clip further includes a latching receptacle.

A universal clamp including a first jaw, a guide, a fixed jaw, an adjustment mechanism, and a coupler. The first jaw has a first clamping face. The guide is coupled to the first jaw. The second jaw has a second clamping face. The second jaw is adjustably connected to the guide to move relative to the first jaw with the first clamping face oriented to face the second clamping face. The adjustment mechanism adjusts and secures the first jaw relative to the second jaw. The coupler is connected to at least one of the first jaw and the second jaw. The coupler is configured to facilitate attachment of a structure to the universal clamp.
