The present invention concerns a fastener (110) for the temporary assembly of at least two previously drilled structures (112) comprising: a hollow body (122) comprising a bearing surface (40); elastic clips (24) which are movable relative to the body and which form a projection relative to the bearing surface; a spacer (26) around which the elastic clips are positioned; a connecting element (130), extending within the body and secured to the elastic clips (24); and an actuating element (132) linked to connecting element by a thread/tapping (67, 84). The connecting element is traversed by a lateral opening (70) axially extended between two closed ends (72, 74); and the fastener also comprises a transverse stop (28) secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.

A connecting assembly for connecting boards includes a rod member and a buckle member. The rod member includes a head portion, a rod body and a tip portion which are integrally formed and connected in sequence. By using an engaging hole to engage with an annular engaging groove, the connection of the boards is more firm due to a circumferential joint. Besides, the buckle member is provided with a cross-shaped groove, which makes it easier for the user to adjust the direction when in use. The structure design is reasonable and more convenient for use.

A coupler for removeable coupling an object to a support. The coupler includes a cover, a ring, and a base. The cover couples to the support. The ring includes a first arm, a second arm, a third arm, a fourth arm, a first stop, and a second stop. Each arm of the ring is formed of a resilient material. The ring is positioned in a cavity of the cover. The base couples to the accessory. The base cooperates with the cover and the ring to couple to the cover and to rotate from a decoupled position to an intermediate position and further to a clocked position.

Systems and methods for coupling a tag to an item. The methods comprise: dispensing the tag from a tag feeder of a tag applicator; performing first operations by the tag applicator to mechanically move the tag into a nest of the tag applicator; determining if a given criteria is met based on feedback information received from at least one of a user of the tag applicator and a sensor provided with the tag applicator; and performing second operations by the tag applicator to couple the tag to the item, when a determination is made that the given criteria is met.

An example toggle bolt catch for use with a toggle bolt is described. The toggle bolt catch includes a collar eyelet and a toggle catch. The collar eyelet includes a cylindrical ring having a central opening to allow the toggle of a toggle bolt to pass through and a flange that extends radially outward from the cylindrical ring. The toggle catch includes a minor arc stem that extends away from a back of the cylindrical ring. In use, the toggle bolt catch is inserted through a hole formed in drywall, for example, with the minor arc stem extending in the open space behind the drywall. When the bolt of the toggle bolt is rotated, the toggle can rotate only until it contacts the minor arc stem, after which further rotation of the bolt will draw the toggle of the toggle bolt toward the bolt without additional rotation of the toggle.

An assembly method and a structure of a control device are introduced. The control device includes a head and a body. The head includes a stopping portion, and the body includes a corresponding stopping portion. The head is movably assembled with the body upon pressurizing the head or the body by an external force. Thus, the head and the body can be quickly assembled into a control device, while achieving effects of easy assembly and better stability after the assembly.

A metal anchoring fastener fastens millwork onto walls constructed with wall cladding fastened to steel studs. The load typical of a loaded cabinet is borne by the steel stud anchors owing to the mate between the profile of the steel stud anchor and the layers of millwork and wall cladding and steel stud that said anchor penetrates. The pitch of the thread adorning the profile of the steel stud anchor progresses non-linearly along the length of said shaft, the shaft is generally non-linear in profile, and the thread profile is non-uniform along the length of said shaft. The anchor can also support a secondary screw concentrically penetrating the void at the center of the anchor, in order to hang loads from a wall, with or without millwork. Predrilling of the holes can enable installation of these zinc anchors.

A fixing device for securing into a hole (30) in plasterboard and providing an anchor point for affixing a load to said plasterboard, the device comprising: a body (12) configured to be retainable in said hole; and a resiliently flexible, elongate bracing member (10) of length greater than an axial dimension of said body (12) and having an opening for receiving an external retention device (28, 128) for enabling manual retention of said bracing member (10) in a bracing position with an inner surface thereof against the rear of said plasterboard, in use, after insertion thereof through said hole (30).

A hanging rack assembly may include a mounting rail having a mounting base. The mounting base has a first end, a second end, a first edge that extends between the first and the second end, and a second edge that extends between the first end and the second end, the mounting base having opposite faces that extend between the first end, the second end, the first edge, and the second edge; and a mounting lip, wherein the mounting base comprises one or more non-circular openings sized to receive an anchor for mounting the mounting rail to a surface. A method of installing a mounting rail may include mounting the mounting rail on a surface; drilling through one or more non-circular openings located on a mounting base of the mounting rail; and inserting an anchor into one or more of the non-circular openings and the surface in order to secure the mounting rail to the surface.
