Abstract

A protective toe for an accident prevention shoe, comprising a sheath that substantially forms the front portion of the shoe, the sheath having an upper portion provided with a plurality of aeration holes. Associated with the aeration hole is a diaphragm that allows only moisture to flow from the inside to the outside of the shoe toe.

Description

  The present invention relates to protective toes for accident prevention shoes. More particularly, the present invention relates to accident-proof shoe toes made from metallic materials, ie iron, alumina or alumina compounds, or plastic materials, or composite materials.

  The shoe toe must be made to pass impact tests according to current policies in different countries.

  In order to pass the impact test, it must exhibit toughness and homogeneity characteristics that can only be imparted by a very precise manufacturing method for shoe toes.

  As an example, a metal shoe toe is made by a molding method, in which the molding material is dripped so as to replicate the shape of the shoe, then the mold is closed, and then, for example, pressure is applied continuously. The material forming the shoe toe is solidified in the mold.

  The shoe toe can be forged by a die casting method.

  In addition, the shoe toe must provide sufficient comfort to the user wearing the accident prevention shoe, particularly with respect to the transpiration of the user's foot, all of which are as described above. Must be done without jeopardizing the properties of.

  For this reason, a plurality of holes are provided at pre-arranged positions on the shoe toe so as to aerate the shoe portion containing the toe.

  Applicant has developed a toe for accident prevention shoes by inserting a diaphragm into the aeration hole that allows only moisture to flow from the inside to the outside of the shoe part where the toe is provided. The toe for shoes which implement | achieved and improved that the moisture which can occur flows from the outer side to the inner side of a shoe was implement | achieved.

  That is, according to one aspect of the present invention, there is a protective toe for an accident prevention shoe comprising a sheath that substantially forms the front portion of the shoe, the sheath having an upper portion provided with a plurality of aeration holes. A shoe toe is provided that has a diaphragm associated with the aeration hole that allows only moisture to flow from the inside to the outside of the shoe toe.

  Other characteristics and advantages of the shoe toe according to the invention are shown in the following exemplary and non-limiting description of the embodiments described with reference to the accompanying drawings.

  Referring to FIG. 1, a shoe toe, indicated generally by the numeral 1 in FIG. 1, includes an upper portion 2, a lateral portion 3, and a base portion 4, which are in front of the shoe. They are joined together so as to substantially define a capsule that forms the portions. The sheath has a substantially vertical rear opening 5 and a substantially parallel bottom opening 6 into which the owner's foot wearing accident prevention shoes is placed.

  Beneficially, the shoe toe has different thicknesses in different parts, thereby reducing both thickness and weight, as well as improving resistance to compression.

  An important fabrication made on a shoe toe is a plurality of pre-arrangements aimed at reducing the amount of alloy used on the shoe toe and with a range to aerate the shoe part containing the toe. The purpose is to make a plurality of aeration holes 7 at the positions. Clearly, these aeration holes cannot be made in shoe parts that require greater resistance to compression.

  More particularly, said aeration hole 7 is made in the upper part 2 and possibly in the lateral part 3 of the shoe toe.

  Associated with the aeration hole is a diaphragm that allows only moisture to flow from the inside to the outside of the shoe toe.

  The diaphragm can be made of, for example, microfiber. Preferably, the diaphragm is associated with the outer surface of the upper portion.

  Alternatively, the diaphragm is associated with the inner surface of the upper portion. Preferably, the diaphragm consists of a single sheet, which is bonded to the part having the aeration holes by an adhesive or by using other different bonding means. Alternatively, the diaphragm consists of a plurality of different portions of the sheet, each located in at least one aeration hole.

  The shoe toe is made of, for example, a metal material, or a plastic material, or a composite material.

  The type of alloy used to make the shoe toe by itself has the proper properties to pass the strength test described above.

  In addition to containing alumina, suitable alloys for making metal shoe toes can contain, for example, copper, silica, magnesium, titanium and iron.

FIG. 2 is a diagram showing an accident prevention shoe toe made according to the present invention.
