Trigger Guard
A trigger guard is a protective loop surrounding the trigger (firearms), trigger of a firearm designed to prevent unwanted contact with the trigger, which may cause an accidental discharge. Other devices that use a trigger-like actuator mechanism, such as inhalers, crossbows and power tools, may also have trigger guards. On rifles with a bottom metal, the trigger guard is often incorporated as part of the bottom metal. Winter trigger guards Some firearms may have their trigger guard removed or repositioned as not to impair use with large cold weather gloves on, especially those intended to be used in arctic conditions. Quite notably, the Accuracy International Arctic Warfare line of rifles have enlarged trigger guards for use in cold climates, primarily northern Sweden.

Trigger (firearms)
A trigger is a mechanism (engineering), mechanism that Actuator, actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a animal trap, trap, a power tool, or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flat or slightly curved lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...

Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...

Accidental Discharge
An unintentional discharge is the event of a firearm discharging (firing) at a time not intended by the user. An unintended discharge may be produced by an incompatibility between firearm design and usage, such as the phenomenon of cooking off a round in a closed bolt machine gun, a mechanical malfunction as in the case of slamfire in an automatic weapon, or be user induced due to training issues or negligence. The phenomenon has also been defined in scientific literature as ''an activation of the trigger mechanism that results in an unplanned discharge that is outside of the firearm’s prescribed use'', where "prescribed use" refers to departmental policies and laws related to the operation of firearms (O'Neill, 2018). Types Accidental discharge An accidental discharge (AD) occurs when there is a mechanical failure of the firearm. This can include things like firearms that do not have mechanisms to render them drop safe falling a sufficient distance, a firing pin stuck forward, a ...

Actuator
An actuator is a machine element, component of a machine that produces force, torque, or Displacement (geometry), displacement, when an electrical, Pneumatics, pneumatic or Hydraulic fluid, hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. An actuator translates such an input signal into the required form of mechanical energy. It is a type of transducer. In simple terms, it is a "mover". An actuator requires a control device (which provides control signal) and a source of energy. The control signal is relatively low in energy and may be voltage, electric current, Compressed air, pneumatic, or hydraulic fluid pressure, or even human power. In the electric, hydraulic, and pneumatic sense, it is a form of automation, automation or automatic control. The displacement achieved is commonly linear or rotational, as exemplified by linear motors and rotary motors, respectively. Rotary motion is more natural for s ...

Inhaler
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications. There are a wide variety of inhalers, and they are commonly used to treat numerous medical conditions with asthma and chronic obstructive pulmonary disease (COPD) being among the most notable. Some of the common types of inhalers include metered-dose inhalers, dry powder inhalers, soft mist inhalers, and nebulizers. Each device has advantages and disadvantages and can be selected based on individually specific patient needs, as well as age, pathological conditions, coordination, and lung function. Proper education on inhaler use is important to ensure that inhaled medication creates its proper effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crossbow
A crossbow is a ranged weapon using an Elasticity (physics), elastic launching device consisting of a Bow and arrow, bow-like assembly called a ''prod'', mounted horizontally on a main frame called a ''tiller'', which is hand-held in a similar fashion to the stock (firearms), stock of a long gun. Crossbows shoot arrow-like projectiles called ''crossbow bolt, bolts'' or ''quarrels''. A person who shoots crossbow is called a ''crossbowman'', an ''arbalister'' or an ''arbalist (crossbowman), arbalist'' (after the arbalest, a European crossbow variant used during the 12th century). Crossbows and bows use the same elastic launch principles, but differ in that an archer using a Bow and arrow, bow must draw-and-shoot in a quick and smooth motion with limited or no time for aiming, while a crossbow's design allows it to be spanned and cocked ready for use at a later time and thus affording them unlimited time to aim. When shooting bows, the archer must fully perform the bow draw, draw, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Tool
A power tool is a tool that is actuator, actuated by an additional engine, power source and mechanism (engineering), mechanism other than the solely manual labour, manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Tools directly driven by working animal, animal power are not generally considered power tools. Power tools can produce large amounts of particulates, including ultrafine particles. Airborne particulate matter is a Group 1 carcinogen. Uses Power tools are used in industry, in construction, in renovation, in the garden, for Homemaking, housework tasks such as Outline of food preparation#Food preparation techniques, cooking, housekeeping, cleaning, and Do it yourself, around the house for purposes of driving (fasteners), drilling, saw, cutting, shaping, sander, sanding, Grinding (abrasive cutting), grinding, router (woodworking), routing, polishing, painting, me ...

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

Bottom Metal
A bottom metal is a firearm component typically made of metallic material (such as aluminium alloy or steel), that serves as the floor of the action and also helps to clamp the receiver onto the stock. The bottom metal also frequently incorporates the trigger guard, for instance on the Mauser 98 and M1 Garand, although a trigger guard by itself is ''not'' considered a bottom metal. In repeating firearms with internal magazines, the bottom metal serves as the magazine floorplate and contains the spring and follower, either as a fixed solid piece or can be opened like a hinged door. Bottom metals designed to accept detachable magazines are called detachable bottom metals (DBM), and contain a rectangular reception slot called the ''magazine well'', with a latch mechanism that securely holds the inserted magazine in place. Single-shot firearms (e.g. SIG Sauer 200 STR) typically do not have bottom metals, and modern firearms with metallic chassis (e.g. SIG Sauer CROSS) do n ...
