Definitions

  • This patent application relates to a weight-lifting belt provided with a self-locking buckle.
  • a weight-lifting belt is known from US-A-3,362,744.
  • the belt according to the present invention has been designed in order to provide a specific, functional tool for those who work in shops or yards, where it is often necessary to lift and move heavy objects - such as beams, pipes, trunks, stacks of arc welded metal meshes - using lifting devices, like cranes, bridge cranes, mechanical arms, etc.
  • the purpose of the present invention is to realise a specific tool used to hold heavy objects moved with lifting devices, characterised by safe, easy operation both during application and removal, with the possibility of repeated use.
  • Another purpose of the present invention is to realise a tool as illustrated above, provided with a self-locking buckle in order to save the operator's time and effort required to tie the object to be lifted.
  • Another purpose of the present invention is to realise a tool as illustrated above, provided with a self-locking buckle that can be opened quickly and easily, in order to save the operator's time and effort required today to untie and loosen the binding means, thus eliminating the risk of injury involved in manual interventions.
  • the tool according to the present invention consists in a resistant belt ending with two eyelets and inserted into a special buckle, provided with a hook and a clamp to hold the belt in place.
  • the buckle comprises a box-like frame in which the belt is inserted and slides.
  • the belt is tightened by a clamp pivoted on a transversal pin supported by the frame of the buckle and subjected to the constant thrust of a spring that pushes it against the belt.
  • the shape of the buckle allows the oscillating clamp to oppose to the free sliding of the belt in one direction only, meaning the direction that allows for loosening the belt. This means that by applying traction on the free end of the belt, the tightening pressure automatically increases gradually.
  • the tool according to the invention comprises a resistant belt (1) whose ends are folded and sewn to form two eyelets (2 and 3).
  • the belt (1) is inserted into a buckle (4) made up of a box-like frame (5), that externally features a hook (6) and internally a transversal pivoting pin (7) for an oscillating clamp subjected to the constant thrust of a return spring (not shown in the enclosed drawings).
  • the spiral spring is inserted into the pin (7) and exerts a pressure on the internal side of the clamp (8) that maintains the front edge (8a) of the clamp pressed against the bottom wall (5a) of the frame (5).
  • the operator simply introduces the hook (6) in the eyelet (3) of the belt (1) after wrapping the belt (1) around the object to be lifted in a safe grip.
  • the operator In order to loosen the belt (1) after moving the object, the operator simply presses the rear edge (8b) of the clamp (8) to allow the belt (1) to slide backwards inside the buckle (4) freely.
