A connector is provided. The connector includes a post defining a first side, a second side, and a first end. The connector further includes a stationary wing formed on the first side of the post and extending away from the first side of the post. The stationary wing is inflexible relative to the post. The connector further includes a flexible wing attached to the second side of the post adjacent to the first end and extending away from second side of the post. The flexible wing is configured to flex relative to the post.

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.

The invention pertains to a modular presentation system for the display and support of goods and a build-up method therefor. The system comprises floor tiles, blocks, and cover plates. Two floor tiles can be interconnected by placing the two floor tiles adjacent and subsequently mounting a connection piece in connection recesses provided in the two floor tiles. Floor tiles, blocks, and cover plates are configured to clamp on top of floor tiles and blocks. The present invention allows to quickly and efficiently build up the modular presentation system.

A flexible shoulder pin module includes a barrel having an annular head portion, a cylindrical body portion, and a through-hole extending from a top surface of the body portion to a bottom end of the head portion; and a shoulder pin having a shaft portion and a shoulder portion formed thereon. The through-hole includes a first portion adjacent to the top surface of the body portion, and a second portion having a greater diameter than the first portion. The shaft portion is insertable through the first portion into the second portion. The shoulder portion is configured to adjustably extend above the top surface of the body portion to clamp a panel thereto. A compressible device is configured to be disposed around the shaft portion and secured by a stopper panel, which is coupled to the shaft portion and placed adjacent to the head portion within the second portion.

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.

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.

Provided are a clip system and method for joining plates using the system of clips, with each clip including a base, a first protrusion, a second protrusion, a first pair of fingers, and a second pair of fingers, with the first protrusion and the second protrusion extending in opposite directions away from the base.

The present invention discloses a display rack for display and exhibition. The display device includes the display rack. Both sides of the display rack are provided with at least one insertion plate and insertion slot respectively, and the outer surface of the display rack is provided with at least one first item placement slot for exhibiting products. The upper side surface and the lower side surface of the inner surface of the display rack are provided with a connector and a groove respectively, the connector is provided with a first threaded hole, and the groove wall of the groove is provided with a second threaded hole. In the present invention, by modular design, a plurality of identical display racks are combined and superposed to form display devices of different width or height, less molds are used in production, so the production efficiency is increased, and production costs are reduced.

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.
