A fixture set for fixing an accessory to a wall includes a bolt; a splitter having a sleeve portion and a wedge portion; and a metal anchor configured to be screwed to the bolt and having radially expandable arms configured to slide along surfaces of the wedge portion when the anchor is urged to slide in a first direction. The arms have a free end configured to lock the anchor against the wall upon radial expansion of the arms. The splitter has a catch situated entirely within minimum bounding cylinder of the sleeve portion. The free end of a respective arm is barbed and configured to be caught in the catch when the anchor is urged to slide in a second direction, opposite to the first direction, after having slid the anchor onto the splitter in the first direction with the barbed free end having passed the catch.

A fastener is provided that includes a housing body including a bore extending along a longitudinal axis from a proximal end of the housing body, a housing body anti-rotation part, and a reduced diameter opening at a distal end of the housing body, a collet body partially translating within the housing body bore, having a collet body anti-rotation part positioned at least partially within the housing body, and a plurality of clamping fingers axially extending from a wall portion of the collet body, and a removable bushing positioned at least partially in the housing body bore. Rotation of the collet body is substantially prevented by an interaction between the housing body anti-rotation part and the collet body anti-rotation part during fastener clamping and unclamping and the removable bushing and the reduced diameter opening in the bore prevent escapement of the collet body anti-rotation part from the housing body.

A releasable fastening device includes a socket, an engagement structure, and first and second lever arms. The socket is insertable into an opening of an object from a first side. The first and second lever arms are pivotably attached to the socket at respective pivot points and are slidably connected to the engagement structure. The fastening device moves between a mounting position where the fastening device is insertable into the object and a fastening position where the fastening device is attached thereto. The first and second lever arms have respective attachment surfaces, respectfully configured to engage a first engagement surface on a second side of the object in connection to the opening in the fastening position and a second engagement surface on the second side of the object in connection to the opening in the fastening position.

An anchor holder for concrete decks comprises a body for being inserted into an opening in a metal deck, the body including an outside vertical wall and an opening for receiving an anchor. The body includes arms normally biased extending outwardly from the vertical wall, the arms being collapsible toward the body when the body is inserted into the opening in the metal deck and expanding outwardly after passing the opening to be disposed below the metal deck. A support is attached to the body, the support to engage a top surface of the metal deck to apply an upward force on the body and keep the collapsible arms engaged against an underside of the metal deck when the body is attached to the metal deck.

A double connector for butt-connecting two components includes a guide bolt having a respective bolt section tapering in the direction of each bolt end on both sides of a middle bolt section. Two spreading sockets are movably guided on the guide bolt and which in each case can be pushed together from an outer socket end position toward the middle bolt section into a mounted position. The two spreading sockets are latched against being pushed back, wherein the spreading sockets each have at least one spreading tab which is expanded outwardly via the guide bolt in the mounted position.

Fasteners and related systems according to the invention include a collet body having a first part of a two part anti-rotation arrangement and a cylinder body having a second part of the two part anti-rotation arrangement wherein the collet body and the cylinder body are mateably axially translatable with respect to each other, and have the same or similar outer diameter in some embodiments or not in others. A threaded member rotationally engages the collet body and compressively contacts the cylinder body during operation of the fastener to creating a clamping effect. Rotational interference between the first and second parts of the anti-rotation arrangement preferably occurs at sectional face portions of at least the collet body. Resistance to induced rotation of the cylinder body relative to a work piece rotation of the threaded member is preferably provided by a tool engaging a tool interface present on the cylinder body.

An anchor holder for concrete decks comprises a body for being inserted into an opening in a metal deck, the body including an outside vertical wall and an opening for receiving an anchor. The body includes arms normally biased extending outwardly from the vertical wall, the arms being collapsible toward the body when the body is inserted into the opening in the metal deck and expanding outwardly after passing the opening to be disposed below the metal deck. A support is attached to the body, the support to engage a top surface of the metal deck to apply an upward force on the body and keep the collapsible arms engaged against an underside of the metal deck when the body is attached to the metal deck.

The system includes a rail mountable to a wall, such as a wall along a hallway in a medical care environment. A cart movable along a floor adjacent to the wall is fitted with an anchor. The anchor is located at the rail, the anchor configured so that it releasably engages the rail, so that the cart can be secured to the rail when not in use. In at least some embodiments, a power source is located within the rail and a power coupler is provided on the cart which is adjacent to the power source in the rail and electrically coupled to the power source, for transmission of power from the power source in the rail to the cart, when of the anchor on the cart is attached to the rail. Thus, the cart is both anchored and recharged simultaneously in such embodiments.

An anchor device for a floor, the anchor device comprising an article securing arrangement to which an article can be secured. The article has a moveable securing mechanism. The article securing arrangement defines a cavity to receive the moveable securing mechanism, and the article securing arrangement includes a co-operating means to co-operate with the moveable securing mechanism in the cavity and secure the article to the anchor device. The anchor device has a height which is no more than 30 mm.

The present invention discloses a blind bolt fastening device, and belongs to the technical field of bolts. The blind bolt fastening device includes Z-shaped gaskets, a fixed plate, elastic hinges, a screw cap, a nut, an integrated gasket and the like. The top end of the screw cap is connected to the fixed plate in a spot welding manner. A plurality of elastic hinges is uniformly mounted on the fixed plate. One end of each elastic hinge is rotatably fixed on the fixed plate. Connection points of the elastic hinges and the fixed plate do not exceed the outer edge of the fixed plate. The other end of each elastic hinge is connected to one Z-shaped gasket in a spot welding manner. In an initial state, the plurality of Z-shaped gaskets are uniformly distributed and fitted onto the outer wall of the screw cap along a circumferential direction. When needing to pass through amounting hole, the plurality of Z-shaped gaskets may be folded through the elastic hinges to the top end of the screw cap and form elastic potential energy for rebounding. The present invention realizes simple and quick single side installation of a bolt and may be widely applied to civil and architectural engineering, mechanical engineering and the like.
