Definitions

  • the present invention relates to a wheel, particularly suitable for use in skates, rollers and the like.
  • wheels which are used in skating/rolling devices, generally comprise a central hub, rigidly connected to a rim aimed at supporting a ring-like tread, usually made of plastics.
  • Such wheels are operatively connected to the frame of the skating/rolling device by way of a system of bearings, which ensure a suitable revolving interconnection with very low friction values.
  • bearings are typically accommodated inside counter-shaped housings provided at the free ends of the hub, along the main rotation axis of the wheel.
  • Such bearings are generally housed in pairs and in opposite positions and are operatively associated by means of a pin, arranged axially along the hub.
  • the aim of the present invention is to provide a wheel, particularly suitable for use in skates, rollers and the like, which allows to achieve an easy, fast locking of the bearings in the respective housings regardless of the type of material used for manufacturing the wheel.
  • Another object of the present invention is to provide a wheel that allows an easy interconnection between the bearings and the respective housings to be accomplished even by personnel who are not particularly skilled.
  • a further object of the present invention is to provide a wheel, which is structurally simple and which can be assembled by means of highly standardised operations at relatively low manufacturing costs.
  • the present invention provides a wheel, particularly for skates, rollers and the like, comprising a central hub, which is connected to an outer rim aimed at providing support to a tread, such central hub comprising: a first end and/or a second end positioned substantially along a main rotation axis of the wheel; and at least a substantially circular first housing, which is approximately positioned at said first end and/or said second end, said first housing accommodating at least a bearing, characterised in that such central hub comprises at least a second housing for accommodating locking means for locking such bearing within such first housing.
  • Figure 1 is a schematic view of an embodiment of the wheel, according to the present invention.
  • Figure 2 is a cross sectional view of the embodiment of the wheel, according to the present invention, illustrated in figure 1. Ways to carrying out the Invention
  • reference numeral 1 indicates a wheel, according to the present invention, which is particularly suitable for use in skates with in-line wheels.
  • the wheel 1 comprises a central hub 2, which is connected to or integrally obtained with an outer rim 3, which provides support for a tread (not shown).
  • the central hub 2 is provided with a first end 4a and/or a second end 4b located substantially along the main rotation axis 100 of the wheel 1.
  • First housings 5a and/or 5b for the positioning of counter-shaped bearings are provided approximately at the first end 4a and/or the second end, respectively.
  • first housings 5a and/or 5b are suitably provided within the first housings 5a and/or 5b.
  • Locking means 7, which are designed for locking such bearings to the first housings 5a and/or 5b, are positioned in the second housings 6.
  • the first housings 5a and/or 5b comprise advantageously substantially circular lateral surfaces 8, on which the bearings are free to roll.
  • the second housings 6 are ring-like shaped, so as to form circular grooves along the lateral surfaces 8.
  • the locking means 7 comprise preferably a ring-like gasket 7, with circular cross section (hereinafter defined as "O-ring").
  • the O-ring 7 is advantageously counter-shaped to the second housing 6, so that it can be accommodated within it.
  • the O-ring 7 is preferably provided with a diameter which is smaller than the diameter of the bearing accommodated in the first housing 5a and/or 5b. In this manner, the O-ring 7 is arranged to protrude internally with respect to the lateral surfaces 8 of the first housing 5a and/or 5b. Thereby, the locking of the bearings within the first housing 5a and/or 5b is ensured.
  • the O-ring 7 is made of a material which is provided with a predefined resiliency level. The resilient deformability of the O-ring 7 allows an interference positioning/fitting of the bearings into the first housing 5a and/or 5b.
  • the wheel according to the present invention achieves the intended aim and objects.
  • the wheel 1 allows a simple, fast locking of the bearings in the respective housings 5 and 5b provided at the ends of the hub.
  • the locking of the bearings is performed regardless of the type of material used for the manufacture of the wheel.
  • this locking system is particularly advantageous when the wheel is made of a metallic material, such as, for example, aluminium.
  • a direct interference can be avoided between the bearings and the respective housings without prejudice for the operation of the wheel.
  • the presence of adhesive materials can be also avoided. Therefore, the assembly of the wheel 1 according to the present invention can be performed with a high level of standardisation, thereby ensuring great uniformity of results, which do not strictly depend on the ability of the operator. Thereby, this brings about a relevant reduction of the manufacturing costs.
