Bored Cylindrical Lock
A bored cylindrical lock is a lockset which is installed by boring two circular holes in the door. Door handles may also use the same installation. Installation Two holes are bored, perpendicular to one another, into the door. The "face bore" is the larger hole which is bored into the door face and a smaller "edge bore" hole is bored into the door edge. The edge may require additional preparation to receive the latch assembly, typically by router (woodworking), routing or chiseling a shallow mortise. Some commercially-sold doors may come prepared to receive one or more bored cylindrical locks, such as entry doors, which typically require both a door knob and dead bolt. In the United States, typically, the face bore is sized from in diameter and is centered at from the leading edge of the door. This distance is referred to as the "backset." Other, less popular, backsets are at . Residential doors are normally prepared with a backset and commercial doors have a backset. The e ...

Lockset
A lockset (alternatively lock set) is the hardware and components that make up the locking or latching mechanism that can usually be found on a door or other hinged object but can also include sliding doors and dividers. The components of a lockset can include (but are not limited to) the door handles (commonly both inside and outside), latch bolt, dead bolt, face plate, strike plate, escutcheon, thumbturn, push button, turn button, and other trim. The lockset and associated hardware typically defines a door's function and how a user could (or could not) access the two adjacent spaces defined by the opening associated with the lockset. Regulation The Americans with Disabilities Act of 1990, under Title III, and many state and local governments regulate locksets in buildings occupied by the public. Typically, locksets that employ doorknob-controlled latches are forbidden for public use in favor of lever handles, which are easier to operate by gravity instead of the grasping and t ...

Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate lock ...

Door Handle
A door handle or doorknob is a handle used to open or close a door. Door handles can be found on all types of doors including: exterior doors of residential building, residential and commercial buildings, internal doors, cupboard doors and vehicle doors. There are many designs of door handle, depending on the appropriate use. A large number of handles, particularly for commercial and residential doors, incorporate latching or locking mechanisms or are manufactured to fit to standardised door locking or latching mechanisms. The most common types of door handle are the lever handle and the doorknob. Door handles can be made out of a plethora of materials. Examples include brass, porcelain, cut glass, wood, and bronze. Door handles have been in existence for at least 5000 years, and its design has evolved since, with more advanced mechanism, types, and designs made. Some door handles are also arm- or foot-operated to reduce transmission of contagious illnesses. Types *The most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bored Cylindrical Lockset Door Preparation
In conventional usage, boredom, , or tedium is an emotion characterized by uninterest in one's surrounding, often caused by a lack of distractions or occupations. Although, "There is no universally accepted definition of boredom. But whatever it is, researchers argue, it is not simply another name for depression or apathy. It seems to be a specific mental state that people find unpleasant—a lack of stimulation that leaves them craving relief, with a host of behavioral, medical and social consequences." According to BBC News, boredom "...can be a dangerous and disruptive state of mind that damages your health"; yet research "...suggest that without boredom we couldn't achieve our creative feats." In ''Experience Without Qualities: Boredom and Modernity'', Elizabeth Goodstein traces the modern discourse on boredom through literary, philosophical, and sociological texts to find that as "a discursively articulated phenomenon...boredom is at once objective and subjective, emoti ...

Router (woodworking)
The router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. It routs (hollows out) an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. They may be handheld or affixed to router tables. Some woodworkers consider the router one of the most versatile power tools. There is also a traditional hand tool known as a router plane, a form of hand plane with a broad base and a narrow blade projecting well beyond the base plate. CNC wood routers add the advantages of computer numerical control (CNC). The laminate trimmer is a smaller, lighter version of the router. Although it is designed for trimming laminates, it can also be used for smaller general routing work. Rotary tools can also be used similarly to routers with the right bits and accessories (such as plastic router bases). History Before power routers exist ...

Chisel
A chisel is a hand tool with a characteristic Wedge, wedge-shaped cutting edge on the end of its blade. A chisel is useful for carving or cutting a hard material such as woodworking, wood, lapidary, stone, or metalworking, metal. Using a chisel involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material. A Chisel#Gouge, gouge is a type of chisel that serves to carve small pieces from the material; particularly in woodworking, woodturning and sculpture. Woodworking Woodworking chisels range from small hand tools for tiny details, to large chisels used to remove big sections of wood, in 'roughing out' the shape of a pattern or design. Typically, in Wood carving, woodcarving, one starts with a larger tool, and gradually progresses to smaller tools to finish the detail. One of t ...

Dead Bolt
A deadbolt or deadlock is a type of lock morticed into a wooden door where a bolt is thrown into the door frame, using a key from either side, to secure the door. It is distinct from a spring bolt lock because a deadbolt can only be opened by a key or handle. The more common spring bolt lock uses a spring to hold the bolt in place, allowing retraction by applying force to the bolt itself. A deadbolt can therefore make a door more resistant to entry without the correct key, as well as make the door more resistant to forced entry. A deadbolt is often used to complement a spring-bolt lock on an entry door to a building. Common types A deadlock, if it is cylinder operated, may be either single cylinder or double cylinder. A single cylinder deadlock will accept a key on one side of the lock, but is operated by a twist knob on the other side. Double cylinder locks will accept a key on both sides and therefore do not require (and often do not have) any twist knob. This prevents un ...

Walter Schlage
Walter Reinhold Schlage (1882–1946) was a German-born American engineer and inventor. Known as the ''Lock Wizard of Thuringia'', he is best known for the bored cylindrical lock and the lock company that bears his name, Schlage Lock Co. Early training and travels Early on in his life, his father recognized his aptitude for mechanics and academics and worked on his behalf to have his son admitted to the Carl Zeiss Optical Works in Jena, Germany. During his apprenticeship, Schlage learned drafting, applied mechanics and engineering. After four years, he graduated with a special award of merit, as a result of his applied scholarship. Walter developed a sense of adventure whetted by guests that stayed in his father's hotel, in Thuringia, Germany. Following his training he left Germany for London where he worked as an instrument maker for Hileger, Ltd. Lasting a year in England, he emigrated to the United States where he gained employment with the Western Electric Company. Wit ...

Rabbet
A rabbet (American English) or rebate (British English) is a recess or groove cut into the edge of a piece of machinable material, usually wood. When viewed in cross-section, a rabbet is two-sided and open to the edge or end of the surface into which it is cut. An example of the use of a rabbet is in a glazing bar where it makes provision for the insertion of the pane of glass and putty. It may also accommodate the edge of the back panel of a cabinet . It is also used in door and casement window jambs, and for shiplap planking. In a picture frame the rabbet may hide uneven or poor edges of a painting and its support, while for graphic art and photographs protective glazing is used. A rabbet can be used to form a joint with another piece of wood (often containing a dado). Rabbet joints are easy to construct, but are not as strong as some other joints. Nails and screws can be added to help increase the overall strength. Etymology The word ''rabbet'' is from Old French '' ... [...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. Mortise lock describes only a method of fitting the lock, and says nothing about the quality or key mechanism. In some 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 properties of all ages 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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latch
A latch or catch (called sneck in Northern England and Scotland) is a type of mechanical fastener that joins two or more objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a strike plate, ''keeper'' or ''strike''. A latch is not the same as the Lock (security device), locking mechanism of a door or window, although often they are found together in the same product. Latches range in complexity from flexible one-piece flat springs of metal or plastic, such as are used to keep Blow molding, blow molded plastic power tool cases closed, to multi-point cammed latches used to keep large doors closed. Common types Deadbolt latch A deadbolt latch is a single-throw bolt. The bolt can be engaged in its strike plate only after the door is closed. The locking mechanism typically prevents the bolt from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
