Definitions

  • the invention relates to a folding-type pooket-tool such as a pocket-knife, with one or more tool-elements whereby the tool-elements can rotate in and out of the holder which serves simultaneously as a protector and as a handle for handling the tool.
  • Pocket-tools are handtools that can be stored in a safe place whereby usually the handle serves simultaneously as the store.
  • a mechanism releases and returns the tool-element to its store, usually a pivot-type arrangement is chosen, whereby the tool-element is rotating around a pin.
  • the pivot-type pocket-tool has usually a spring that keeps the tool-element in place. By overcoming the springaotion usually by pulling at the tool-element, it snaps into open position. Similarly, by overcoming the springaction in open position, the tool-element snaps into closed position.
  • the invention as claimed is intended to remedy these drawbacks. It solves the problem of how to design a pooket-tool and similarly retractable tools in whiph the forces are transmitted to the handle by means of a cylinder with solid flanges, of such dimensions that it has a similar strength and resistance against bending as the tool-element itself.
  • the aperture of the cylinder and the flanges and their sizes give the pocket-tool a firm grip and a greatly ncreased width of the tool-element at the location of the cylinder sothat a looking device for insranoe consisting of a spring loaded catoh and chamber arrangement can operate with sufficient strength at the rim of the tool-element thereby adsorbing severe operating Forces. It may be also possible to slip the forefinger through the aperture thereby improving the grip remarkably. By reducing the cross section of the pocket-tool after the cylinder, an extra safeguard and a further improved grip is achieved.
  • the advantages offered by the invention are manifold: the rivetted ends of the pins, used normally for rotating the tool-elements, are not anymore pulled through the coverglates and the coverplates are not being bent which loosens the tool-elements.
  • Accidents with pocket-tools are greatly reduced now that the tool-element cannot collapse, fold back and out the operators hand. Also the hand is protected against sliding into the sharp edges of the tool, and it oan now be made easily possible to replace tool-elements. Without complicating the pocket-tool by adding devices, the pocket-tool has become more effective, safer to operate, can be handled with greater force and has become extremaly durable.
  • the figures 1, 2 and 3 show a pocket-tool in closed position comprising essentially a tool-element 1, a cylinder 2 around which the tool-element 1 can rotate, a springloaded looking device 3 securing the tool-element 1, ooverplates 4, separatingplates 5 and lifting handles 6, 7 and 8.
  • the tool-element 1 is firmly placed with flat surfaces between flat mating surfaces of separatingplates 5 or coverplates 4. Likewise the innersurfaoes of the flanges 19 of cylinder 2 rest firmly and with flat surfaces against mating surfaces of the ooverplates 4.
  • the springloaded looking device 3 is keeping the tool-element 1 secured when catch 9 falls in chamber 10 which can be achieved by rotating tool-element 1 around cylinder 2.
  • Lifting the looking device 3 can be accomplished in various ways, in figure 1 for instance a recess 12 is provided which can have various shapes and can also be a void.
  • a recess 12 is provided which can have various shapes and can also be a void.
  • By pulling disengagement of catch 9 is achieved.
  • the surface of tool-element 1 over which catch 9 moves falls back at location 13 where tool-element 1 is nearing its restposition as is shown in figure 1 and 2. This secures the tool-element 1 in its restposition.
  • lifting handles 6 and 7 are shown as variations for lifting the springloaded looking device 3 when more force is required then can be reasonably expected from a thumbnail.
  • Handle 6 pivots around pin 15 which runs through the separatingplates 5 and ooverplates 4.
  • Separatingplates 5 are having a recess 16 to accommodate handle 6.
  • On handle 6 a stud 17 is provided resting with one side against the springloaded arm of looking device 3. When lifting and rotating handle 6, stud 17 rotates and lifts looking device 3 whereby face 18 becomes engaged.
  • Handle 7 pivots around pin 15 in the same chamber that gives accommodation to the tool-element 1 thereby lifting looking device 3.
  • a oross-section of the cylinder 2 is given showing an alternative solution to the looking of the tool-elements 1 and plates 4 and 5; instead of for instanoe direct riveting, a ring 20 is slipped over the unfinished end of the cylinder till it meets a stepwise increase in the diameter at the location of endplate 4 sothat ring 20 is looked in the right position when the cylinder extension is rolled into a flange.
  • the advantage of this variation is that the landing force of ring 20 onto ooverplate 4 by which the tool-elements 1 are looked can be well controlled.
  • Ring 20 can have a circular shape or any other shape to improve its strength.
  • Figure 3 shows a looking device whereby catch 9 extends over all tool-elements 1, serving all tool-elements 1 simultaneously.
  • any lifting device cam be used for lifting the looking device 3 any lifting device cam be used.
  • Shown is a handle 8 rotating around cylinder 2.
  • Rim 21 in contact with catch 9 is curved such that a larger radius lifts the looking device 3 when handle 8 is rotating.
  • looking device 3 is provided with a window 22.
  • the fixed end of looking device 3 for instance has recesses 23 for accommodating separatingplates 5.
  • Holes 24 for instance indicate a fastening means for coverplates 4, separatingplates 5 and the locking devioe(s) 3.
  • a a double cylinder consisting of an inner cylinder 25 and an outer cylinder 26 are screwed in each other with matohing thread sothat the toll-elements 1, separatingplates 5 and coverplates 4 are looked together as tight as required between the surfaces 27 and 28.
  • the position of the two cylinders 25 and 26 can be secured for instance with a spring 29 provided in one of the ooverplates with a butt 30 that fits into a recess in the flange of one of the cylinders 25 and 26 while the other cylinder flange for instance is secured for instance with a fixed pin.
  • This construction allows replacement of tool-elements 1 and oleaning.
  • An other method of securing the two cylinders together is for instance by rolling the inner cylinder end into a flange 31 fitting a recess in the flange of the outer cylinder 26 fer instance as shown in detail B.
