Definitions
- the invention relates to a safety boot made of an elastic deformable, polymeric material, comprising a shaft and a Outsole, with a protective cap in the shaft in the area of the forefoot is embedded and the upper of the outsole with a Cover layer covered.
- a safety boot of the aforementioned type is known.
- the outsole will molded onto the top layer of the shaft in the molten state and subsequently solidified in the course of a cooling process. it consists of a homogeneous block of material. If the setting is soft, the result is: Consequence of this a good attenuation of the appearance, which however is to the detriment of Wear resistance goes.
- high wear resistance results, but it does result inevitably a large resistance to deformation and as a result a very high one unsatisfactory comfort. The result of this is the consequence that there are no known safety boots that are comfortable to wear and combine good wear resistance.
- the invention has for its object a safety boot type mentioned in such a way to develop that Ensuring good wear resistance of the outsole is better Bending elasticity and better shock absorption during the intended use results.
- the Outsole is separated from the cover layer by a packing and that the Filler has a lower resistance to deformation than that Outsole.
- the filler is expedient from that which forms the outsole Material body completely enclosed on all sides except for a narrow zone in the Edge area. Impact loads striking the underside of the outsole are therefore unable to affect the area of the shaft.
- the abrasion-resistant material body forming the outsole is appropriate pulled up in the edge area around the packing. Also in the outsole has a good mechanical sideways direction Resilience on what prevents yourself Surface damage results in which look ugly Can store dirt.
- the packing can be provided on the top side with a puncture-proof intermediate layer be covered, for example an intermediate layer made of sheet steel. Injuries to the human foot caused by penetrating nails or similar foreign bodies can be reliably prevented.
- the filler body can have an edge region which is a component of the Outer contour of the shaft and the outsole forms. This will not only the shaft in terms of vibration technology from the actual outsole uncoupled, but also when using a contrasting color Material for the production of the packing created a possibility to change the appearance of the safety boot positively. Of the this impression can be intensified in which such an edge area, based on the outer contour of the outsole, is pulled outwards. Of the prevents ring-shaped, self-contained bead formed in this way also that the outer contour at a vertical load Outsole can move outwards in an uncontrolled manner, which makes one spongy would require a soft appearance and from an ergonomic point of view is not desired.
- the filler should preferably consist of a material body that with the material body forming the shaft and the outsole is compact is.
- the Filler and the shaft results from molten materials from this a firm bond of the individual components to each other, what the mechanical overall durability of the safety boot improved.
- the safety boot is expediently in its entirety Created material bodies that belong to the same material group, for example made of PVC, TPE or TPU.
- a particularly soft appearance can be achieved if the filler forming material body is foamed.
- the packing the outsole vertically at least at one point with a projection break through below. This can be up to the contact surface of the outsole the subsurface be extended.
- a projection is provided on the underside with a stud profile consequently one or more of those in the area of the bottom of the outsole existing studs.
- Pore volume 20 to 60% by volume of the total available volume include.
- an impact damping and deformability with a view to achieving good comfort is desirable under normal conditions.
- a reduced pore volume is recommended for lightweight ones larger pore volume.
- Safety boot comprises a shaft 1, which does not match one in the drawing textile stocking shown is lined and consists of PVC and one, based on the shaft 1 contrast-colored outsole 2, which is also made of PVC exists and is connected to the shaft.
- the stocking can be used if necessary be omitted.
- the shaft 1 and the outsole 2 are a puncture-proof Intermediate layer 3 inserted from a steel sheet and a filler 4 foamed PVC.
- the filler 4 is provided with an edge area 5, which is part of the outer contour of the shaft 1 and the outsole 2 forms and the safety boot on its entire outer circumference encloses.
- the shaft 1 is thereby of the outsole 2 separated.
- the filler 4 with its edge area 5 can be in a contrasting color be executed. In terms of taste, this can be positive Achieve effects.
- the filler 4 has a pore volume of 30% of the total available Volume. It is provided with a projection 6 which the outsole 2 in Area of the paragraph breaks through vertically downwards and at a distance from the performance area ends.
- the cross-sectional area of the protrusion should be expediently 20 to 40% of the total available Take the tread of the heel. Especially with one Execution results in good shock absorption.
- a substantially non-deformable protective cap for example a protective cap 7 made of steel.
- the achieved by the liner 3 This complements the protective effect.
- the outsole 2 consists essentially of a very thin-walled shell made of relatively hard PVC. Despite being good bendability this ensures good abrasion resistance.
- the outsole 2 can remaining in a manner known per se to be provided with a stud profile to improve slip resistance.
- the studs can be inside again consist of components of the packing.
- the safety boot according to the invention can be used using a Generate three-color spray device relatively easily and inexpensively.
- a lower part of the tool which in a first operation
- Production of the outsole 2 is used
- successive tool upper parts assigned which is a direct molding of the packing to the Outsole enables and then the molding of the shaft 1 that now includes the outsole 2 and the filling body 4 lower part of the Safety boots.
- the production of the safety boot according to the invention in semi or fully automated processes in this way proportionately simply possible.
