Handcuff
Handcuffs are restraint devices designed to secure an individual's wrists in proximity to each other. They comprise two parts, linked together by a chain, a hinge, or rigid bar. Each cuff has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist. Without a key, handcuffs cannot be removed without specialist knowledge, and a handcuffed person cannot move their wrists more than a few centimetres or inches apart, making many tasks difficult or impossible. Handcuffs are frequently used by law enforcement agencies worldwide to prevent suspected criminals from escaping from police custody. Styles Metal handcuffs There are three main types of contemporary metal handcuffs: chain (cuffs are held together by a short chain), hinged (since hinged handcuffs permit less movement than a chain cuff, they are generally considered to be more secure), and rigid solid bar handcuffs. While bulkier to carry, rigid handcuffs per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belly Chain (restraint)
A belly chain (also known as a waist chain or Martin chain) is a physical restraint worn by prisoners, consisting of a chain around the waist, to which the prisoner's hands may be chained or cuffed. Sometimes the ankles are also connected by means of longer chains. Usage Such restraints are often used in the United States in courtrooms, or for transporting prisoners, or in other public situations as a safeguard against escape. They are used above all when detainees are to be restrained over a longer period of time, for example during transport or at court hearings. Belly chains are used because there still remains a relatively large freedom of movement to the detainee when their hands are cuffed in front of the body. As an alternative, the hands could be cuffed behind the detainee's back, but this will soon inflict discomfort and even pain when being handcuffed like this for a longer period of time. Therefore, as a more gentle but almost equally secure alternative to cuffing th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hiatts Speedcuffs
Speedcuffs are a model of handcuff characterised by their rigid grip between the two ratchet cuffs. Their rigid design and the inclusion of a grip makes them effective for gaining control over a struggling prisoner, even if only one cuff has been applied. They are standard issue for most police forces within the United Kingdom. Construction Speedcuffs consist of two conventional ratchet handcuffs connected by a rigid metal bar, which is enclosed in a plastic grip secured with bolts. Removal of the grip offers no advantage to escape, as it is only present to facilitate the comfortable manipulation of the cuffs by the arresting officer. Weighing 390 g (13.75 oz) and with a maximum dilation of 23.2 cm (9.13 inches),Hiatts speedcuff rapid control system retrieved on May 6, 2007 the speedcuffs are slig ...

Handcuff Cover
A handcuff cover is a plastic or metal cover that can be placed over a pair of handcuffs. It consists of a hinged, box-like assembly locked over the handcuff chain, wristlets and keyholes. The first handcuff cover was invented by J. D. Cullip and K. E. Stefansen and patented in 1973. It is made from high-strength, high-impact ABS plastic and is still distributed by C & S Security Inc. as "Black Box" handcuff cover. Other companies sell similar devices, e.g. CTS Thompson ("Blue Box" handcuff cover) or Sisco restraints. A handcuff cover has two key purposes: * It converts a pair of standard chain link handcuffs into rigid handcuffs, providing a rather more severe restraint. * It covers the keyholes of the handcuffs for further security. In most cases, a handcuff cover is used in combination with a ''martin link'' belly chain which fixes the handcuffs at waist level. This provides a rather uncomfortable restraint and may result in injury to the individual if maintained for an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physical Restraint
Physical restraint refers to means of limiting or obstructing the freedom of a person's or an animal's bodily movement. Basic methods Usually, binding objects such as handcuffs, legcuffs, ropes, chains, straps or straitjackets are used for this purpose. Alternatively different kinds of arm locks deriving from unarmed combat methods or martial arts are used to restrain a person, which are predominantly used by trained police or correctional officers. This less commonly also extends to joint locks and pinning techniques. Purpose in humans Physical restraints are used: * primarily by police and prison authorities to obstruct delinquents and prisoners from escaping or resisting British Police officers are authorised to use leg and arm restraints, if they have been instructed in their use. Guidelines set out by the Association of Chief Police Officers dictate that restraints are only to be used on subjects who are violent while being transported, restraining the ...

Hinge
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom. Hinges may be made of flexible material or moving components. In biology, many joints function as hinges, such as the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt, although it is nearly impossible to pinpoint exactly where and when the first hinges were used. In Ancient Rome, hinges were called cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''cardinal''. According to the Oxford English Dictionary, the English word ''h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fetters
Legcuffs are physical restraints used on the ankles of a person to allow walking only with a restricted stride and to prevent running and effective physical resistance. Frequently used alternative terms are leg cuffs, (leg/ankle) shackles, footcuffs, fetters or leg irons. The term "fetter" shares a root with the word "foot". Shackles are typically used on prisoners and slaves. Leg shackles also are used for chain gangs to keep them together. Metaphorically, a fetter may be anything that restricts or restrains in any way, hence the word "unfettered". History The earliest fetters found in archaeological excavations date from the prehistoric age and are mostly of the puzzle lock type. Fetters are also referenced in ancient times in the Bible (, , ) A variety of restraint types already existed in Roman times. Some early versions of cup lock shackles existed at this time. These were widely used in medieval times, but their use declined when mass production made the manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the oppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrest
An arrest is the act of apprehending and taking a person into custody (legal protection or control), usually because the person has been suspected of or observed committing a crime. After being taken into custody, the person can be questioned further or charged. An arrest is a procedure in a criminal justice system, sometimes it is also done after a court warrant for the arrest. Police and various other officers have powers of arrest. In some places, a citizen's arrest is permitted; for example in England and Wales, any person can arrest "anyone whom he has reasonable grounds for suspecting to be committing, have committed or be guilty of committing an indictable offence", although certain conditions must be met before taking such action. Similar powers exist in France, Italy, Germany, Austria and Switzerland if a person is caught in an act of crime and not willing or able to produce valid ID. As a safeguard against the abuse of power, many countries require that an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hogtie
The hogtie is a method of tying the limbs together, rendering the subject immobile and helpless. Originally, it was applied to pigs (hence the name) and other young four-legged animals. Agriculture uses The hogtie when used on pigs and cattle has it where three of the four limbs are tied together, as tying all four together is difficult and can result in harm to the animal. Human uses When performed on a human, a hogtie is any position that results in the arms and legs being bound, both tied behind the person and then connecting the hands and feet. The practice has been called inhumane. Typically, the person's feet are restrained with legcuffs or similar devices, and handcuffed with the hands behind the back. The feet are pulled behind the person, until the hands and feet can be connected. (The head and neck are left free.) The restrained person is then placed on the stomach, in a face-down prone position, which decreases the risk of the restrained person kickin ...

Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be ...
