| A foldable bow saw movable between a functional saw condition and a folded packable condition includes a handle arm, a top bar, a short arm, a saw blade, and a lever arm, all pivotally connected one to the other with an end of the handle arm and an end of the lever arm forming free, unconnected ends of the assembly. The free end of the handle arm includes a connecting fulcrum surface adapted to removably mate with a fulcrum surface receiver in the lever arm. Rotation of the lever arm in a locking direction about the fulcrum surface moves the pivotal connection of the lever arm to the saw blade to a tensioned functional saw condition. Rotation of the lever arm in an unlocking direction allows the fulcrum surface to be removed from the fulcrum surface receiver and the assembly to be folded to the packable condition. | ||||||

| A wire saw with sawteeth strip updating structure is provided. A buckling structure is designed in the wire saw. The buckling structure is hidden the handle portion of the saw and includes a connecting unit and a combining unit. The connecting unit can be buckled or unbuckled from the combining unit. The sawteeth strip is connected to the combining unit in a tense state. In updating, the user only needs to push a guide sheet to release the connecting unit from the combining unit. Then the sawteeth strip is taken out easily from the saw for updating a new one. The operation is unnecessary to clamp the saw by a great force for the updating operation. | ||||||

| 15 | Portable hand saw | US09135790 | 1998-08-18 | US06298564B1 | 2001-10-09 | Rudy Voser; Walter Frei |
| The present invention is a lightweight collapsible hand saw for use when camping, hiking or otherwise. The saw breaks down and can be consolidated into a single tubular shape, with all of the components fitting inside the tube. In the functional configuration, a triangular saw may be constructed out of two tubular members having different diameters, a saw blade and a tightening element. Alternatively, both a triangular saw and a buck saw may be constructed out of three tubular members having different diameters, a saw blade and a tightening element. The tubular members form the frame of the saw and contain slots for inserting the saw blade. The tightening element is provided to give the saw the necessary rigidity and impart the necessary tension on the blade. In addition, the apparatus can be used to form a campfire cooking utensil with a number of accessorising elements. | ||||||
