Definitions

  • the present invention relates to a clamp joint intended to grab around a cylindrical body, such as a rod or pipe, and hold it.
  • Fig. 1 shows the Easylift in perspective (prior art)
  • Fig. 2 shows the clamp joint when opened (prior art)
  • Fig. 3 shows the clamp joint when closed (prior art)
  • Fig. 4 shows a gasket which is fitted to a component of the clamp joint
  • Fig. 5 shows the gasket inserted into said component

  • Fig. 7 shows a clamp joint equipped with several gaskets
  • Fig. 8 shows an adapter
  • Fig. 9 shows the adapter provided with a gasket
  • the Easylifter as it is illustrated in Fig. 1, is an additional handle which is clamped forward on the shaft of e.g. a snow shovel.
  • the clamp joint itself as it is illustrated in Fig. 2, includes a U-shaped part with three components 1, 2, 3 hinged together. The components have an inner shape adapted to the round shape of a shaft.
  • the first component 1 has a hinged locking flap 4. When the clamp joint is pressed together around a shaft, the locking flap 4 will be brought behind a locking hook 5 on the third component 3, and be turned down towards the outside of the first component, see Fig. 3.
  • the second component 2 has holes for fastening the handle itself.
  • At least one of the components is provided with a gasket, the gasket being placed on the inside of the component between the U-shaped part and the cylindrical body that is to be fixed.
  • the gasket is made of an elastic material, such as rubber or another material suited for the purpose.
  • the outside of the gasket is adapted to the shape of the corresponding component in the U-shaped part with supporting ribs, etc., so that the gasket may be mounted in the component and fixed as it fills the space between the component and the cylindrical body.
  • Fig. 6 shows the gasket in detail.
  • the gasket is curved according to the shape of the corresponding component in the U-shaped part.
  • the outside is shaped to fill in the inside of the component, and the outside is provided with suction cups projecting from the surface of the gasket.
  • the clamp joint may grab bodies of varying diameter.
  • the clamp joint is pressed around the cylindrical body, the suction cups are pressed against the support creating a vacuum below at least some of the cups.
  • the clamp joint will hold very tightly on the cylindrical body.
  • Fig. 7 shows the clamp joint provided with gaskets in all components. It will grab around the whole perimeter of the body that is to be grabbed.
  • the invention includes a clamp joint that may be used in all situations where there is a need for fixing something to a cylindrical body, this may be to connect something to the body, holding the body fixed, or e.g. joining two cylindrical bodies.
  • the invention is not limited to being used on tool shafts.
  • gaskets there may be any number of components in the clamp joint, with gaskets below all, or an arbitrary number of the components.
  • the gaskets may be adapted to cover the area around its component only, or may be prolonged to cover an area outside the associated component, such as a neighbouring component, or the area below the hinging between the two components.
  • the locking flap 4 may be made eccentric around the hinge line forming a cam on the side adjacent to the gasket (not shown).
  • the locking flap will grab around the back of the locking hook 5 and be pressed inwards so it is approximately tangential with the cylindrical body.
  • the cam at the back of the locking flap will be pressed inwards against the back of the gasket.
  • Fig. 8 shows an adapter that is adapted to be laid into the clamp joint allowing the joint to grab square-shaped bodies.
  • the adapter is made in plastic, in two parts that are joined in a hinge line. It is intended to be laid inside the clamp joint.
  • Fig. 9 shows an adapter which is provided with an inside gasket.
  • the gasket may be designed with a flat or cylindrical inside, allowing it to grab bodies of any shape.
  • the embodiment shown in the figure is designed to grab cylindrical bodies.
  • Adapters may also be provided in which the inside is circular, i.e. for grabbing cylindrical bodies of smaller diameter, e.g. 12-14 mm. With two layers of gaskets a very stable connection is achieved.
