  "claims": [
    "1. A hook for suspending cables and hoses, said hook is comprised of: 45 to 800 grams of an injection molded composition comprised of a polybutylene terephthalate resin, 18% to 22% per total weight of the composition glass-fiber; one or more flame retardants; and one or more UV stabilizers; and wherein said hook has a maximum load bearing of 0.3 to 0.8 kg per gram composition. 2. The hook of claim 1, said hook having first and second spherical ends connected to each other by an S-shaped body, the first spherical end including an opening, the second spherical end including an opening. 3. The hook of claim 1, wherein said one or more flame retardants are selected from the group consisting of minerals, organohalogen compounds and organophosphorus compounds. 4. The hook of claim 3, wherein said minerals are selected from the group consisting of aluminium hydroxide, magnesium hydroxide, huntite and hydromagnesite, hydrates, red phosphorus, boron compounds and borates. 5. The hook of claim 3, wherein said organohalogen compounds are selected from the group consisting of chlorendic acid derivatives, chlorinated paraffins; organobromines, decabromodiphenyl ether, decabromodiphenyl ethane, polymeric brominated compounds, brominated polystyrenes, brominated carbonate oligomers, brominated epoxy oligomers, tetrabromophthalic anyhydride, tetrabromobisphenol A) and hexabromocyclododecane, optionally in combination with antimony tri- or pentoxide or sodium antimonate. 6. The hook of claim 3, wherein said organophosphorus compounds are selected from the group consisting of triphenyl phosphate, resorcinol bis(diphenylphosphate), bisphenol A diphenyl phosphate, tricresyl phosphate, phosphonates, dimethyl methylphosphonate, phosphinates, and aluminium diethyl phosphinate. 7. The hook of claim 1, wherein said one or more flame retardants are selected from the group consisting of tris(2,3-dibromopropyl) phosphate, chlorinated organophosphates, tris(1,3-dichloro-2-propyl)phosphate and tetrakis(2-chlorethyl)dichloroisopentyldiphosphate. 8. The hook of claim 1, wherein said one or more UV stabilizers are selected from the group consisting of oxanilides, benzophenones, benzotriazoles, hydroxyphenyltriazines and hindered amine light stabilizers. 9. The hook of claim 8, wherein said injection molded composition further comprises heat stabilizers. 10. The hook of claim 9, wherein said heat stabilizers are selected from the group consisting of metallic soaps and calcium stearate. 11. The hook of claim 1, wherein said injection molded composition further comprises one or more fluorescent compounds or particles, pigments and/or polyehtylene. 12. The hook of claim 1, wherein said hook is comprised of Valox™ Resin 4521, Amite TV4 240 S supplemented with one or more UV stabilizers; or RAMSTER PF321G4NT supplemented with one or more UV stabilizers. 13. A method for providing a hook for suspending cables or hoses according to claim 1, the method comprising: a) preparing a mixture of a thermoplastic polyester resin, 18% to 22% per total weight of the mixture glass-fiber, one or more flame retardants and one or more UV stabilizers as defined in claim 1; b) drying and compounding the mixture of step (a) to allow injection molding; c) injecting the compounded mixture of step (b) into a mold for a hook, the hook having first and second spherical ends connected to each other by an S-shaped body, the first spherical end including an opening, the second spherical end including an opening; and d) cooling and subsequently removing the injection molded hook from said mold. 14. The hook of claim 2, wherein a distance between the first spherical end and the S-shaped body is from 2-8 centimeters (cm) and a distance between the second spherical end and the S-shaped body is from 3 cm to 14 cm, and wherein a height of the hook is from 5 to 75 cm. 15. The method of claim 13, wherein a distance between the first spherical end and the S-shaped body is from 2-8 centimeters (cm) and a distance between the second spherical end and the S-shaped body is from 3 cm to 14 cm, and wherein a height of the hook is from 5 to 75 cm"

  "description_excerpt": "The present invention relates to an improved hook for cable management during, for example, maintenance, turnarounds, construction works and industrial works. The present invention especially relates to an improved hook of an injection molded glass-fiber reinforced thermoplastic resin for suspending cables or hose pipes. The present improved hooks are capable of safely bearing high loads in the range of 30 to 400 kg. The present invention also relates to methods for providing the present improved hooks.\n\nHooks are well-known and are used on a wide scale for fastening and/or bearing cables or hose pipes such as, for example, electricity cables, welding cables, air hoses, hydraulic hoses and fire hoses. The hooks are useful wherever such cables or hose pipes are used. Examples are the (petro)chemical industry, the offshore industry, the steel and aluminum industry, the ship building industry, oil and gas extraction, the mining industry, the prefabricated construction industry and power stations. Suspending the cables or hose pipes from the wall or the ceiling prevents people tripping over them. Moreover, it reduces the risk of cables or hose pipes becoming damaged, which could result in the leaking of noxious substances or the occurrence of short circuiting, with the consequence of fire hazard.\n\nAlthough cables and hose pipes can be fastened to the ceiling or to the wall by means of conventional hooks, the danger of unintentional and undesirable contact still exists, with the above-mentioned associated hazards.",
