The invention provides a system for positioning a viewing screen. The system comprises a base body and at least one screen body. The screen body comprises a suspension hook and, on the one hand, is configured to be rigidly connected, at least in one position of the screen body, to the base body and, on the other hand, is configured to fasten a viewing screen thereto. The system further comprises a securing body for releasably securing the rigid connection between the base body and the screen body. The base body comprises a suspension edge. The suspension hook and the suspension edge are configured to suspend the screen body from the suspension edge of the base body via the suspension hook.

A low-PIM dual pipe clamp and associated mounting bracket for securing a first pipe transverse to a second pipe at a cellular base station antenna site. The dual pipe clamp accommodates a range of pipe diameters with lower PIM generation, cost, and weight characteristics compared to conventional dual pipe clamps traditionally used at cell sites. The low-PIM dual pipe clamp minimizes the number of parts to upper and lower mounting brackets connected by linear threaded rod connectors, such as bolts, avoiding the use of U-bolts known to create PIM interference in conventional designs. The dual pipe clamp secures first and second pipes against each other in transverse orientations (e.g., horizontal and vertical), as typically utilized to mount antennas at cellular base stations. Each mounting bracket includes first and second pipe restrainers that bias the first and second pipes against each other as the threaded rod connectors are tightened.

The present invention relates to, in a first aspect, a fixing device comprising an anchor element that is positioned along an axis, the anchor element extending substantially perpendicular thereto, a rotating element arranged perpendicular to and rotatable about the axis, and spaced therealong from the anchor element, and a deployment mechanism, comprising a first deployment portion on the anchor element and a second deployment portion on the rotating element, wherein one of the first and second deployment portions comprise a sloping surface extending at least partway around the axis, and the other is shaped to be able to roll, slide or otherwise move along the sloping surface, the anchor element and rotating element are able to move towards one another along the axis, and the deployment mechanism is adapted to convert movement of the anchor element and rotating element towards one another into helical movement in a first-handed direction along and about the axis. Also provided are a fixing device for fixing an article to a structure, a system comprising a fixing or fastening device, and a method of using a fixing device.

A binding structure for attaching two structures to each other, said binding structure comprising an elongated body portion having a first end portion and a second end portion. A head portion is provided in the first end portion and in the second end portion, wherein said head portion protrudes radially from (at least a portion of) the body portion.

A mounting assembly includes a mounting block. A first shaft is supported by the mounting block and movable about a first rotational axis and a first extension axis with respect to the mounting block. A second shaft is coupled to the first shaft and movable about a second rotational axis.

A nut adapted to disengage with a threaded bolt, the nut comprising a base portion integrally formed to a top portion. The nut includes a bore positioned along a central axis through the base portion and the top portion, wherein the top portion is tapered between circumference of the base portion and the bore of the top portion. The tapering is at an angle between 0° to 45° relative to the diameter of the base portion; the base portion comprises at least two cavities, wherein the at least two cavities extend vertically into the base portion.

Bonding clips used to electrically bond metal structures are provided. The bonding clips include an electrically conductive body, an electrically conductive first leg, an electrically conductive second leg and an electrically conductive mounting member. The first leg has one or more piercing members extending from the first leg in a first direction. The second leg has one or more piercing embers extending from the second leg in a first direction. The one or more piercing members are provided to penetrate protective coatings on metal structures so that the one or more piercing members contact the underlying metal.

A scaffolding tube clamp having a pair of body portions defining a top and a base that are hinged together and receivable about a scaffolding tube. A rotatable bolt is received through a hole in the top a hole in the base portion. The bolt has a lower end with engagement means to releasably secure the bolt to the base. The bolt's head has a lower surface that is engageable with a surface on the top. The lower surface of the head, and the surface of the top that is engaged thereby, have complimentary ramped configurations such that when the bolt is rotated the ramps engage, resulting in the ramps moving the top toward the base. In an alternate embodiment the bolt is threaded with two sets of threads that have different diameters and different pitches and that are threadably received within the holes in the top and bottom.

A net repair patch latching unit comprising one or more carabiners. The carabiner of the net repair patch latching unit comprises at least one load-bearing section; a spine and a forepart; one or more first grooves configured to accommodate a yarn of the net to be repaired; at least one elongated bendable part having a distal end and a proximal end. The elongated bendable part comprises at least one transitional bending area connecting the spine and the proximal end of the at least one bendable part; one or more guiding nudges protruding from the load-bearing section; one or more attaching element protruding from the load-bearing section.

A clamping device for connecting a bicycle rack to a bicycle includes a first clamp, a second clamp and a bar. Two ends of the bar respectively extend through the first and second parts. The second clamp includes a first part and a second part. The second part includes a first engaging portion formed to the outside thereof. The first engaging portion includes a recess and multiple first teeth formed to the inner periphery of the recess. A block is partially engaged with the recess and connected to a connection end of one of the two ends of the bar that protrudes beyond the second part. The block includes a second engaging portion which is engaged with the recess and includes second teeth which are engaged with the first teeth so that the block is not freely rotated relative to the second clamp.
