Definitions

  • the present invention refers to a fastening device according to the preamble of independent claim 1 as well as to the preamble of independent claim 5. Furthermore, the present invention is directed to a waste container, and to a method of mounting a first component to a second component by making use of a fastening device according to the invention. Finally, the present invention is directed to different preferred methods of manufacturing such fastening devices.
  • DE 1 097 117 A for example describes a fastening device which is configured as a cylindrical expansion dowel.
  • the dowel which is made of a plastic material, is slotted over a part of its length.
  • the rear end of the dowel has an opening for inserting a fastening screw.
  • the front end of the dowel is provided with sawtooth-shaped incisions on the dowel circumference.
  • EP 2 182 223 A2 describes a nail dowel comprising an expansion sleeve and an expansion pin being a nail, a screw nail, a screw or the like.
  • the expansion pin is arranged in a ready-to-use state as an insert in the expansion sleeve and is encapsulated with the material that forms the expansion sleeve.
  • the expansion pin is not completely, but only partially encapsulated. The expansion pin can thus be driven into a receiving space of the expansion sleeve after the nail dowel has been introduced into a borehole. The expansion sleeve expands outwardly and the nail dowel can get fastened in the ground.
  • the expansion pin made of steel is inserted as an insert into an injection moulding tool.
  • this method is complex and it needs several manufacturing steps.
  • Fastening devices which are configured as so-called hinge pins and which form part of a hinge device, are widely used to pivotably secure a first component, a lid device for example, to a second component, a container body of a container for example.
  • a container can be provided as a waste container for example.
  • hinge pins are generally used to pivotably link a lid device to a waste container body.
  • Known hinge pins of that kind which are generally provided as solid body components, are made of an elastomeric material. Their diameter is slightly larger than the diameter of a receiving sleeve of the hinge device. The hinge pins are hammered into the receiving sleeve under the exertion of an impact force. As a result, the hinge pins are squeezed together and thus generate a form-fitting connection.
  • hinge pin diameter must be synchronized to the inner diameter of the receiving sleeve of the hinge device. If the hinge pin diameter is too large, it is not possible to push the hinge pin into the receiving sleeve of the hinge device. On the other hand, if the hinge pin diameter is too small, no adequate connection can get realized. In situations, where an exchange of a hinge pin due to the exchange of a respective component of the waste container takes place on-site, it is therefore necessary to have different sized hinge pins at hand. This leads to an increased effort. This effect is increased by a number of elements added in the modular system in time or with modifications of existing elements. With each new element or change, the tolerance field increases. In time hinge pins therefore need to adapt to growing tolerances.
  • EP 2 218 223 A2 are therefore not suitable to get transferred to such hinge pins as described above, since they are not universally useable with hinge devices, in particular receiving sleeves of hinge devices, of different sizes.
  • a fastening device in particular a hinge pin, said fastening device consisting of an expansion sleeve and an expansion pin being provided as a drive-in pin, wherein the fastening device is universally useable for different sized applications, in particular receiving sleeves, wherein the fastening device can get re-used, and wherein, at the same time, the fastening device can get manufactured easily and cost-effectively.
  • this object is solved according to a first aspect of the invention by the fastening device with the features according to independent claim 1, according to a second aspect of the present invention by the fastening device with the features according to independent claim 5, according to a third aspect of the present invention by the waste container with the features according to independent claim 12, according to a fourth aspect of the present invention by the method of mounting a first component to a second component by means of such a fastening device according to the present invention according to independent claim 14, and according to a fifth aspect of the present invention by the method of manufacturing such a fastening device according to the present invention according to independent claim 15.
  • the fastening device consisting of the expansion sleeve and the expansion pin is configured in a special way.
  • both aspects underlie the same common basic idea, that a fastening device is provided that can get easily and cost-efficiently manufactured, whereby the fastening device is universally useable on site in connection with different sized applications, and wherein the fastening device can get re-used. Preferred embodiments for both aspects are described in more detail further below.

  • the present invention is not limited to a specific number of slots. At minimum it is necessary that the hollow sleeve body comprises one such slot. However, it is preferred that the hollow sleeve body comprises two or more such slots, three or four slots for example. According to a preferred embodiment, the hollow sleeve body comprises four slots. Four slots give the hollow sleeve body sufficient flexibility to get it easily assembled in a receiving sleeve.

  • the expansion pin When the expansion pin is pushed through the receiving space of the hollow sleeve body, at least parts of the outer surface of the expansion pin get in contact with the inner surface of the hollow sleeve body, in particular with the wall or walling thereof.
  • the expansion pin exerts a pressure force on the inner surface of the hollow sleeve body, in particular on the material areas being provided between adjacent slots in the sleeve body, such that the material areas between the slots get expanded outwards.
  • the overall expansion of the expansion pin perpendicular to the lengthwise expansion of the expansion pin is preferably a bit longer than the inner diameter of the hollow sleeve body.
  • the moving expansion pin will expand the sleeve body of the expansion sleeve, in particular the material areas between adjacent slots, by means of which any tolerance in a receiving sleeve of a component can get bridged, for which the fastening device is used, and which will be described in more detail further below.
