A connection assembly adapted to join a surface element to an underlying support structure while maintaining a substantially zero gap abutting relation between the surface element and the support structure. The connection assembly includes a press-in retainer with a circumferential seal having a sealing foot. The sealing foot flexes about a living hinge while maintaining continuous sliding contact with the support panel without interfering with downward movement of the retainer.

A connection device for fastening two expanded cellular confinement structures includes: an insertion member; an integral shank extending perpendicular from the insertion member; and an integral handle member extending perpendicular from the shank at an end of the shank remote from the insertion member. One or more barbs may project from the insertion member. The device can have a washer section between the handle member and insertion member. The handle can be curved, or it can be in the shape of a polygon.

A grill cover is configured to be utilized with a grill having a metallic component, the grill cover includes a cover body, a magnetic fastener, and a secondary fastener. The cover body presents an outer edge disposed along a bottom side and a cover void therein configured to receive the grill therein. The magnetic fastener and the secondary fastener are each secured to the cover body. The magnetic fastener is configured to provide a magnetic force to keep the magnetic fastener selectively secured to the metallic component of the grill so as to keep the cover body in place around the grill therein. The secondary fastener is configured to reduce a cross-sectional area of the cover void so as to prevent the grill cover from being removed from the grill while the secondary fastener is emplaced.

A stud locking tool is equipped with a first clip and a second clip for sandwiching a mounting member. The mounting member is mounted in a member to be mounted by locking the stud. The first clip has a hollow inner cylindrical portion inserted into a mounting hole of the mounting member. A first flange is located at one end of the inner cylinder portion, and a locking claw is formed inside the inner cylindrical portion and engages with a thread of the stud. The second clip has a hollow outer cylinder portion sized to surround the inner cylinder portion of the first clip. A second flange is located at one end of the outer cylinder portion. An engagement claw extends from the outer cylinder portion and engages the first clip. An inclined surface adjacent to the outer cylinder portion includes a stud guiding surface.

In some examples, an apparatus can include a base plate to interface with a printing device, where the base plate includes an extension member having a pawl, and a lock ring, where the lock ring includes a blocking key, where the lock ring is to interface with the base plate such that the blocking key prevents rotation of the extension member to lock the base plate to the printing device.

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.

A fastener unit and related method for securing a board to a support is provided. The fastener unit includes a spacer block, a grip element extending from the spacer block and configured to fit in and engage a groove of the board, and one or more board engagement elements extending from a portion of the spacer block. The board engagement elements can clamp the board, between an upper and/or lower surface of the board and a groove of the board, thereby securing the spacer block in a position adjacent the groove to establish a gap between the board and another board. Related methods of use also are provided.

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.

A construction support device is disclosed for support and assembly of planar members into complex structures. A construction support device can comprise a first and second unit that are separable where each support unit comprises a plurality of sinuate grooves between a plurality of sections with sinuate edges. The sections are flexible about a center to increase the width of the sinuate grooves to receive greater thickness of planar members. A cubic embodiment with flat outer surfaces and a spheric embodiment with round outer surfaces are disclosed.

A press-in retainer includes a retainer head having a collar and a seal disposed at least partially about the collar. A clip portion projects from the collar. The seal includes a main body engaging the collar and a sealing foot disposed entirely outboard from the collar. The sealing foot is configured to hinge about an intersection of the sealing foot and body portion while remaining entirely outboard from the main body. In a substantially flattened condition of the sealing foot, an angle between the sealing foot and a distal surface of the main body approaches a flat contiguous surface.
