Buckle (food)
A buckle or clasp is a device used for fastening two loose ends, with one end attached to it and the other held by a catch in a secure but adjustable manner. Often taken for granted, the invention of the buckle was indispensable in securing two ends before the invention of the zipper. The basic buckle frame comes in a variety of shapes and sizes depending on the intended use and fashion of the era.Meredith, Alan and Gillian. (2008). ''Buckles''. Oxford: Shire Library. pg. 5. Buckles are as much in use today as they have been in the past: used for much more than just securing one's belt, instead they are one of the most dependable devices in securing a range of items. The word "buckle" enters Middle English via Old French and the -4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... and the Latin ''buccula'' or "cheek-strap," as for a helmet.

Thermoplastic
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. In this state, thermoplastics may be reshaped, and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendering, and extrusion. Thermoplastics differ from thermosetting polymers (or "thermosets"), which form irreversible chemical bonds during the curing process. Thermosets do not melt when heated, but typically decompose and do not reform upon cooling. Above its glass transition temperature and below its melting point, the physical properties of a thermoplastic change drastically without an associated phase change. Some thermoplastics do not fully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fanny Pack
A waist bag, fanny pack, belt bag, moon bag, belly bag (American English), or bumbag (British English) is a small fabric pouch worn like a belt around the waist by use of a strap above the hips that is secured usually with some sort of buckle. The straps sometimes have tri-glide slides, making them adjustable in order to fit properly. It can be considered as a purse worn around the waist. Although traditionally the bag is worn with the pouch at the front, the separate American and British names derive from the fact that they are often worn with the pouch above the buttocks, for which "fanny" and "bum" are respective slang terms in each country. In France, they are known as banana bags, in Spain and Poland as kidney bags, in Italy as the ''marsupio'', from marsupium. In Costa Rica, they are called a skippy or canguru. The modern bags resemble those used from antiquity in some cultures and have gone in and out of fashion from the second half of the 20th century. From the mid- ...

Personal Flotation Device
A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water. The device will keep the wearer afloat with their head and mouth above the surface – they do not have to swim or Treading water, tread water in order to stay afloat and can even be unconscious. PFDs are commonly worn on small watercraft or other locations where accidental entry into deep water may occur in order to provide immediate support for the wearer should they end up in the water. PFDs are also kept on large vessels for passengers to wear in an emergency in order to help them stay afloat should they be forced to enter the water or accidentally fall Man overboard, overboard during an evacuation. PFDs are commonly worn for swimming and other activities that require an indiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safety Harness
A safety harness is a form of Personal protective equipment, protective equipment designed to safeguard the user from injury or death from falling. The core item of a fall arrest system, the harness is usually fabricated from rope, Wire rope, braided wire cable, or Webbing, synthetic webbing. It is attached securely to a stationary object directly by a Carabiner, locking device or indirectly via a rope, cable, or webbing and one or more locking devices. Some safety harnesses are used in combination with a Shock absorber, shock-absorbing lanyard, which is used to regulate deceleration and thereby prevent a serious G-force injury when the end of the rope is reached. An unrelated use with a materially different arresting mechanism is bungee jumping. Though they share certain similar attributes, a safety harness is not to be confused with a climbing harness used for mountaineering, rock climbing, and Climbing gym, climbing gyms. Specialized harnesses for animal rescue or transfer, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pet Harness
A pet harness is equipment consisting of straps of webbing that loop nearly around—that fasten together using side release buckles—the torso of an animal. These harnesses generally are made to have both a strap on the chest in front of the forelimbs, and a strap around the torso behind the forelimbs, with straps in between connecting these two. Having a D-ring suitable for ( pet tags and) a leash to clip to, they are most often used to restrain an animal, but dogs also particularly wear them to assist a person with a disability or haul people and items. There is also the ''lifting harness'' for dogs with disabilities. Harnesses come in different sizes, although many are size-adjustable with tri-glide slides to loosen or shorten the straps' length. The straps may come in a range of different colors, and some have reflective coating. For physical restraint The most common use of the pet harness is for physically restraining an animal. When used as such, the harness is w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belt Buckle
A belt buckle is a buckle, a clasp for fastening two ends, such as of straps or a belt (clothing), belt, in which a device attached to one of the ends is fitted or coupled to the other. The word enters Middle English via Old French and the Latin ''buccula'' or "cheek-strap," as for a helmet. Belt buckles and other fixtures are used on a variety of belts, including Cingulum militare, cingula, Baldric#Roman balteus, baltea, baldrics and later waist-belts. Types Belt buckles go back at least to the Iron Age and a gold "great buckle" was among the items interred at Sutton Hoo. Primarily decorative "shield on tongue" buckles were common Anglo-Saxon grave goods at this time, elaborately decorated on the "shield" portion and associated only with men. One such buckle, found in a 7th-century grave at Finglesham Anglo-Saxon cemetery, Finglesham, Kent during excavations by Sonia Chadwick Hawkes in 1964 bears the image of a Nudity in combat, naked warrior standing between two spears ...

Cropped Tri-glide Slide
Cropping is the removal of unwanted outer areas from a photographic or illustrated image. The process usually consists of the removal of some of the peripheral areas of an image to remove extraneous visual data from the picture, improve its framing, change the aspect ratio, or accentuate or isolate the subject matter from its background. Depending on the application, this can be performed on a physical photograph, artwork, or film footage, or it can be achieved digitally by using image editing software. The process of cropping is common to the photographic, film processing, broadcasting, graphic design, and printing businesses. In photography, print, and design In the printing, graphic design and photography industries, cropping is the removal of unwanted areas from the periphery of a photographic or illustrated image. Cropping is one of the most basic photo manipulation processes, and it is carried out to remove an unwanted object or irrelevant noise from the periphery of ...

Snap-fit
A snap-fit is an assembly method used to attach flexible parts, usually plastic, to form the final product by pushing the parts' interlocking components together. There are a number of variations in snap-fits, including cantilever, torsional and annular. Snap-fits, as integral attachment features, are an alternative to assembly using nails or screws, and have the advantages of speed and no loose parts. Snap-fit connectors can be found in everyday products such as battery compartment lids, snap fasteners and pens. History Snap-together connectors have been used for thousands of years. The first ones were metal. Some of the oldest snap-fits found are snap fasteners, or buttons, shown on the Chinese Terracotta Army featuring soldiers from the late Warring States period. Metal snap fasteners, spring clips, and other snap-type connectors are still in broad use today. With the development of new flexible yet springy materials, such as molded plastic, and new manufacturing processes, many ...

Nylon
Nylon is a family of synthetic polymers characterised by amide linkages, typically connecting aliphatic or Polyamide#Classification, semi-aromatic groups. Nylons are generally brownish in color and can possess a soft texture, with some varieties exhibiting a silk-like appearance. As Thermoplastic, thermoplastics, nylons can be melt-processed into fibres, Thin film, films, and diverse shapes. The properties of nylons are often modified by blending with a variety of additives. Numerous types of nylon are available. One family, designated nylon-XY, is derived from diamines and dicarboxylic acids of carbon chain lengths X and Y, respectively. An important example is nylon-6,6 (). Another family, designated nylon-Z, is derived from amino acid, aminocarboxylic acids with carbon chain length Z. An example is nylon-[6]. Nylon polymers have extensive commercial applications, including uses in textiles and fibres (such as apparel, flooring and rubber reinforcement), molded components fo ...
