A fastening assembly includes a mounting cylinder frame, a movable part and a turnover part, the mounting cylinder frame is provided with a first vertical beam and a transmission rod, the mounting cylinder is provided with a butting block at the top of the first vertical beam, the transmission rod passes through the butting block, the side wall of the first vertical beam is provided with a bulge, the movable part is connected with the transmission rod, and the turnover part is arranged on the first vertical beam and rotationally connected with the movable part. The turnover part is butted with the bulge, the turnover part is located between the butting block and the movable part, and has a vertical state and a horizontal state. The transmission rod is used to drive the turnover part to switch between the horizontal state or the vertical state.

An anchoring device for insertion in a hole provided in a structure such as a wall (hollow or solid) comprises proximal and distal sections. The proximal section includes a head defining an aperture for receiving a fastener, and the distal section includes a pair of expandable wings displaceable between collapsed and expanded positions. Each wing is biased towards its expanded position such that the wings can engage the structural material delimiting the hole or a distal surface of the structure. The distal section comprises, proximally of the wings, a variable-length flexible portion for allowing the wings to engage the distal surface of the structure for various structure thicknesses. The distal section comprises, distally of the wings, a tip section adapted to spread outwardly when engaged by the fastener. The proximal section comprises a pair of legs each having a toothed rack for engaging the structural material.

A support assembly that includes a structural member that is delimited by a first end and a second end with a first end cap configured to be at least partially disposed within the first end of the structural member and a second end cap configured to be at least partially disposed within the second end of the structural member to mount the structural member to a structure. The support assembly allows for forces to be applied in all directions without causing rotation or disengagement of the support assembly from a mounting structure.

This invention relates to a fixing device for holding a fastener in a hole in a structure comprising an actuating part configured to engage with said fastener in use and a plurality of arms extending from and hingedly connected to the actuating part, each arm comprising a distal portion and an anchor portion between the distal portion and the actuating part. The arms are an insertion configuration formed or formable by moving the arms from an initial configuration in which the arms are splayed to the insertion configuration in which the arms are substantially aligned so that the distal portions define an axial passage and, in use, the fastener extends through the axial passage to engage with the actuating part, and cooperation of the fastener with the actuating part moves the actuating part in an axial direction towards the distal portions to cause a part of each of the anchor portions to move in a radially outward direction with respect to the axial passage to anchor the fixing device in said hole.

A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

An offset hygienic anchor sealing bracket for installation of block style tube and pipe hangers to a paneled strata in which there is no access to the reverse side, there being a need to secure the anchor bracket to an anchor bolt or toggle bolt and simultaneously shield the exposed toggle bolt structure from the environment of the clean room, sterile room, or sanitary room in order to protect the irregular surface of the toggle bolt from caustic cleaning solutions and to prevent the build up of dirt and bacteria, the anchor bracket having bored pedestals in communication with the cavity which encapsulates the exposed portion of the toggle bolt and secures the anchor bracket thereto, the anchor bracket having a plurality of female threaded receptacles for receipt of fasteners utilized in assembling block style tube and pipe hangers, thus securing the block style tube and pipe hanger to the panel at a desired slope and center line.

This invention is a movable, transferable and reusable umbrella type anchor for suspending or securing attachments to a hollow back surface.

An anchor (910) for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end (918) adapted to be engaged by a rotatable tool (B) to rotate the anchor (910) about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor (910) also includes a distal end (912) adapted to cut through the wall (W) as the anchor (910) is rotated, and a shank (920) extending between the proximal and distal ends (918, 912). The shank (920) includes at least one expandable leg (924) that is in a collapsed position thereof when the anchor (910) is rotated to mount it to the wall (W) and that is located distally beyond a non visible surface of the wall (W) once the anchor (910) has been mounted to the wall and is in a first position thereof. The wall anchor (910) includes an outer thread (922) that securely engages the wall (W). A threaded fastener (B), e.g. a screw, is adapted to be introduced in the anchor (910) and to threadably engage the same distally of the leg (924) such that sufficient rotation of the threaded fastener (B) retracts the distal end (912) towards the proximal end (918) thereby causing the leg (924) to displace to a laterally expanded position thereof and to engage the non visible surface of the wall (W).

A mounting structure has: a first member in which a first through-hole is formed; a second member in which a second through-hole is formed; and a clip having a first shaft portion, a first anchor portion that is anchored on an edge portion of the first through-hole, a second shaft portion whose axial center is eccentric with respect to an axial center of the first shaft portion, and a second anchor portion that is anchored on an edge portion of the second through-hole, wherein a cross-sectional shape of a portion, which is disposed at an inner side of the first-through hole, of the first shaft portion is a polygonal shape, and a length along a longest diagonal line of the polygonal shape, or a length of a longest side of the polygonal shape, is longer than a minimum opening length of the first through-hole.
