Coffin Lock
Coffin lock is a slang term for a blind panel connector (also called a butt-joint fastener) often used in scenic construction to join together stage decks or scenery in a butt joint. These are two part connectors (male and female) that draw together and lock. The two most common types are the cam and acceptor and more traditional hook and pin version. These devices generally use a hex key to operate the locking mechanism via a small diameter hole either through the face or rear of the panel. When locked, the considerable mechanical advantage Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for ... offered by the cam or hook holds the panels tightly together. Coffin locks can be installed directly into a mortise cut into each panel for total concealment except for the locking hole or mount ...

Coffin Locks
A coffin is a funerary box used for viewing or keeping a corpse, either for burial or cremation. Sometimes referred to as a casket, any box in which the dead are buried is a coffin, and while a casket was originally regarded as a box for jewelry, use of the word "casket" in this sense began as a euphemism introduced by the undertaker's trade. A distinction is commonly drawn between "coffins" and "caskets", using "coffin" to refer to a tapered hexagonal or octagonal (also considered to be anthropoidal in shape) box and "casket" to refer to a rectangular box, often with a split lid used for viewing the deceased as seen in the picture. Receptacles for cremated and cremulated human ashes (sometimes called cremains) are called urns. Etymology First attested in English in 1380, the word ''coffin'' derives from the Old French , from Latin , which means '' basket'', which is the latinisation of the Greek κόφινος (''kophinos''), ''basket''.

Scenery
Theatrical scenery is that which is used as a setting for a theatrical production. Scenery may be just about anything, from a single chair to an elaborately re-created street, no matter how large or how small, whether the item was custom-made or is the genuine item, appropriated for theatrical use. History The history of theatrical scenery is as old as the theatre itself, and just as obtuse and tradition bound. What we tend to think of as 'traditional scenery', i.e. two-dimensional canvas-covered ' flats' painted to resemble a three-dimensional surface or vista, is a relatively recent innovation and a significant departure from the more ancient forms of theatrical expression, which tended to rely less on the actual representation of space senerial and more on the conveyance of action and mood. By the Shakespearean era, the occasional painted backdrop or theatrical prop was in evidence, but the show itself was written so as not to rely on such items to convey itself to the audien ...

Butt Joint
A butt joint is a technique in which two pieces of material are joined by simply placing their ends together without any special shaping. The name "butt joint" comes from the way the material is joined. The butt joint is the simplest joint to make since it merely involves cutting the material to the appropriate length and butting them together. It is also the weakest because unless some form of reinforcement is used (see below), it relies upon glue or welding alone to hold it together. Because the orientation of the material usually presents only one end to a long gluing or welding surface, the resulting joint is inherently weak. Nonetheless, it generally provides sufficient strength in most cases, particularly when fasteners are used. The butt joint is widely used in many applications due to its simplicity, notably in rough carpentry and construction. Methods The butt joint is a very simple joint to construct. Members are simply docked (cut off) at the right angle and have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hex Key
Hex keys of various sizes Socket head screws of various sizes A hex key (also, hex wrench, Allen key and Allen wrench) is a simple driver for bolts or screws that have heads with ''internal'' hexagonal recesses (sockets). Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly-shaped screw sockets. The rods are bent to 90º, forming two arms of unequal length resembling an "L". The tool is usually held and twisted by its long arm, creating a relatively large torque at the tip of the short arm; it can also be held by its short arm to access screws in difficult-to-reach locations and to turn screws faster at the expense of torque. Hex keys are designated with a socket size and are manufactured with tight tolerances. As such, they are commonly sold in kits that include a variety of sizes. Key length typically increases with size, but not necessarily proportionally so. Variants on this design have the short end i ...

Mechanical Advantage
Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device trades off input forces against movement to obtain a desired amplification in the output force. The model for this is the ''law of the lever.'' Machine components designed to manage forces and movement in this way are called mechanism (engineering), mechanisms. An ideal mechanism transmits power without adding to or subtracting from it. This means the ideal machine does not include a power source, is frictionless, and is constructed from rigid bodies that do not deflect or wear. The performance of a real system relative to this ideal is expressed in terms of efficiency factors that take into account departures from the ideal. Levers The lever is a movable bar that pivots on a wikt:fulcrum, fulcrum attached to or positioned on or across a fixed point. The lever operates by applying forces at different distances from the fulcrum, or pivot. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortise Lock
A mortise lock (also spelled mortice lock in British English) is a lock that requires a pocket—the mortise—to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the United States. The design is widely used in domestic properties of all vintages in Europe. History Mortise locks have been used as part of door hardware systems in the US since the second quarter of the eighteenth century. In these early forms, the mortise lock mechanism was combined with a pull to open the unlocked door. Eventually, pulls were replaced by knobs. Until the mid-nineteenth century, mortise locks were only used in the most formal rooms in the most expensive houses. Other rooms used box locks or rim locks; in contrast with embedded mo ...

Stagecraft
Stagecraft is a technical aspect of theatrical, film, and video production. It includes constructing and rigging scenery; hanging and focusing of lighting; design and procurement of costumes; make-up; stage management; audio engineering; and procurement of props. Stagecraft is distinct from the wider umbrella term of scenography. Considered a technical rather than an artistic field, it is primarily the practical implementation of a scenic designer's artistic vision. In its most basic form, stagecraft may be executed by a single person (often the stage manager of a smaller production) who arranges all scenery, costumes, lighting, and sound, and organizes the cast. Regional theaters and larger community theaters will generally have a technical director and a complement of designers, each of whom has a direct hand in their respective designs. Within significantly larger productions, for example a modern Broadway show, effectively bringing a show to opening night requires th ...
