Definitions

  • the invention relates to a device for: supporting the elbow joints of a person involved in the grinding of glassware on a worktop of a grinding machine.
  • This object is achieved according to the invention by a device with the features specified in the characterizing part of claim 1.
  • the advantages achieved by the invention are, in particular, that the person engaged in the grinding work can now support the elbows in the usual way without fear of damage to the ulnar nerve. Two pressure areas outside the endangered zone then form on each elbow, the pressure areas also being substantially larger than when the joint is simply placed on the worktop.
  • the simplest version of the support ring would be safe to produce it directly from an elastic material, for example from foam. However, it should be taken into account here that these materials can easily tire.
  • the support ring is therefore expediently designed as a hose which is filled with a medium, depending on the elasticity of the hose casing, to a greater or lesser extent under pressure.
  • Granulate can also be used as a filling, whereby the granulate can consist of minerals (sand) as well as plastic.
  • the support ring can be made of a permanently plastic material, for example a plasticine which is enclosed by an elastic film, consists.
  • the support ring is molded, the support ring then more or less maintaining this shape.
  • the support ring is designed essentially as a gas-tight hose which is inflated with air or another gas.
  • This has the additional advantage that the support ring can be inflated to different degrees depending on the intended load. For the grinding of relatively heavy objects that lead to a high pressure load on the support ring, a more inflated support ring can be used from the outset in order to keep the pressure areas on the support ring or on the arms small.
  • the support ring is placed on a trough-like support surface of a rotatable support frame, the support surface of the support frame being inclined relative to the worktop.
  • the support ring is expediently provided with an exchangeable skin-compatible textile cover.
  • FIG. 1 there is a support frame 2 on a worktop 1, which can be rotated about a bolt 3 which is seated vertically in the worktop 1.
  • the support structure 2 has a trough-shaped contact surface 4 for the support ring 5, which thus rests immovably on the support structure 2.
  • the bearing surface 4 for the support ring 5 is inclined in relation to the worktop 1.
  • the support ring 1 is almost completely filled with liquid 6, so that it has a white deformability to enlarge the support or contact surfaces even without any significant pressure application keeps.
  • the elbow joint 9 of the angled arm 10 of a glass grinder is inserted into the clear width 8 of the support ring 5.
  • two contact surfaces 11, 12 are formed on the support ring 5, which absorb the pressure generated during grinding (see also FIG. 2).
  • the inside width 8 of the support ring 5 and its cross-sectional radius 14 are dimensioned such that the elbow joint 9 of the angled arm 10 cannot completely penetrate the inside width 8.
  • the tip 15 of the elbow joint 9 in FIG. 1 extends, for example, only just above the center line 16 of the support ring 5.
  • the elbow joint 9 or the angled arm 10 When the elbow joint 9 or the angled arm 10 is pressed onto the support ring 5, this deforms slightly, as already explained. This is shown somewhat exaggerated in Figure 3.
  • the contact surfaces 11, 12 of the arm 10 on the support ring 5 are hereby enlarged.
  • the wall of the support ring also consists of an elastic film 17, e.g. like a rubber hose.
  • a heating cartridge 18 for tempering the liquid filling 6 is also let into the support ring 5.
  • the heating cartridge 18 extends with its outer connection into a corresponding recess 19 of the support frame 2. This heating cartridge is of course only useful if a support ring with liquid filling is used.
