Definitions

  • a pair of scissors comprise a pair of blade members preferably made of bright steel sheeting and including each a blade part and a handle part with plane faces; a pivot pin connecting said blade members with one another at the end ponions of the blade parts adjacent the handle part, and two initially separate grasp eyes each made of a section of bright material and secured to its associated handle part at large-area plane faces formed on said handle part and said grasp eye.
  • Each of the two blade members of the scissors hitherto used is made in one piece by hot or cold forming or by punching out. Manufacturing the blade members in one piece, however, involves substantial loss of material. Furthermore, the grasp eyes must be punched out, which is not possible after the stamping of the halves of the scissors without deforming the walls of the grasp eyes. The grasp eyesmust be finished on their inner and outer circumference and possibly also on the long sides. This surface finishing, which in contrast to the machine-done surface finishing of the rest of the blade members must be accomplished by skilled workmen, is the most time and cost-consuming work that must be done in the course of the surface finishing of the scissors-halves.
  • Scissors are also known of which the grasp eyes are made of plastics material and are, for example, molded to the lower ends of the handle parts of the scissors.
  • the grasp eyes in this case need no finishing but are endangered by breakage? It has also been suggested to manufacture the grasp eyes themselves out of metal and to fasten them to the handle parts of the blade members.
  • scissors are known which have grasp eyes made of bent wire.
  • the connection of such grasp eyes with the handle parts by means of hard soldering which would not destroy the surface of the parts to be joined at the soldering spots, is not possible due to the small contact surfaces between the parts.
  • a connection by means of welding would lead to the destruction of the surface of both parts at the welding spot, which necessitates costly finishing involving removal of material.
  • scissors which have grasp eyes consisting of tube'sections.
  • the production of the grasp eyes from tube sections however merely. leads to savings in material, since the surface of these grasp eyes must still be finished.
  • With respect to the attachment of such grasp eyes to the handle parts of the scissors the same difficulti'es arise as with the attachment of grasp eyes made of wire bent to shape.
  • a further object of the invention is improving the connection of the grasp eyes to the handle parts of the tools, so that the grasp eyes are securely attached thereto.
  • a scissors-like tool particularly a pair of scissors, which comprises a pair of blade members preferably made of bright steel sheeting and including each a blade part and a handle part with plane faces; a pivot pin connecting said blade members with one another at the end portions of the blade parts adjacent the handle parts, and two initially separate grasp eyes each made of a section of bright material and secured to its associated handle part at large-area plane faces formed on said handle part and said grasp eye.
  • eachinitially separate grasp eye may be in the form of a bow having two large-area free end portions, made of a section of bright material and secured at said largearea free end portions to one of the plane faces of its handle part.
  • each of the grasp eyes may have an obllong straight circumferential portion secured to one of the plane faces of the handle part.
  • the surface finishing of the grasp eyes previously required for scissors having independently produced grasp eyes becomes superfluous, so that the tool in its entirety can be produced in an economical manner from bright material.
  • a fully secure attachment of the grasp eyes to the handle parts of the tool is ensurered, since the grasp eyes having a portion of their circumference formed straight are attached to the handle parts of the tool along the full length of said straight portion, so that they are connected by comparatively large areas to the handle parts, whereas, on the other hand, the bows forming the grasp eyes beside the handle parts are attached over the relatively wide width of the handle parts, so that they are also'connected by relatively large areas.
  • the pressure required for the execution of a cut is'taken up nearly exclusively by the handle parts, so that the grasp eyes have merelyrto fulfil the function of guiding the fingers passed through the grasp eyes.
  • the initially separate grasp eyes or the bows forming together with the handle parts of the tool the grasp eyes are preferably thicker in cross section than the handle parts, so that a portion of each eye projects beyond its associated handle part and forms an abutment for the handle part associated with the other grasp eye.
  • the grasp eyes or the bows forming the grasp eyes beside the handle parts thus serve as stops for the handle parts when the tool is being closed. This makes any offsetting of the handle parts required for example in the case of one-piece stamped scissors-halves superfluous.
  • FIG. 2 is an end view, on an enlarged scale and seen in the direction of the arrow A, of a detail of FIG. 1;
  • FIG. 3 is a fragmentary elevational view of an opened pair of scissors according to another embodiment of the invention.
  • FIG. 4 is a similar view of an opened pair of scissors according to still another embodiment of the invention.
  • FIG. 5 is a side view, on a larger scale and seen in the direction of the arrow B in FIG. 4, of the handle part of one of the blade members of the scissors, and
  • FIG. 6 is an end view, on an enlarged scale and seen in the direction of the arrow C, of a detail of FIG. 4.
  • FIGS. 1 and 2 show a pair of scissors according'to the invention, which consist of two blade members 1 and 2 each of which include a handle part and a blade part having a cutting edge.
  • the blade members 1 and 2 are detachably connected with one another at the end portions of the blade parts adjacent the handle parts by means of a pivot pin 3.
  • Initially separate grasp eyes 4 and 5 which each consist of a section of a tube made of bright-drawn material and bent into the desired shape of the grasp eyes, are secured to the handle parts of the blade members 1 and 2.
  • the handle parts include at least one elongated planar face located along the same side of the blade members 1 and 2 as the cutting edge.
  • the circumference of each grasp eye has an oblong straight portion having an elongated planar surface as is eviderit in the drawings.
  • the elongated planar surface of the grasp eye closely contacts along its entire length, i.e., by a large'surface, this elongated planar face of the handle part and is secured thereto by hard soldering for example.
  • the elongated planar surface of each grasp eye 4 and 5 is fitted onto a parallel, elongated planar face of the associated handle part.
  • each bow or eye 4 and 5 In a direction which extends normal to that of the general plane of the scissors, the elongated straight portion of each bow or eye 4 and 5 is, in cross section, thicker than its associated handle part so that a portion of the bow projects beyond said handle part and forms an abutment for the other handle part when the scissors are being closed.
  • the pair of scissors are provided with grasp eyes 6 and 7 which are each made of a section of a bright-rolled steel band bent to shape.
  • the grasp eyes 6 and 7 have an elongated form.
  • the circumference of the grasp eyes 6 and 7 also has an oblong straight portion having an elongated planar surface as shown.
  • Each of the grasp eyes 6 and 7 engages with its elongated planar surface of the oblong straight portion, the elongated planar face of its associated handle part and is secured thereto along the entire length of its elongated planar surface by hard soldering for example.
  • the grasp eyes 6 and 7 project with one of their longitudinal edges beyond the handle parts and form an abutment for the other handle part.
  • grasp eyes 8 and 9 are provided which are formed by the handle parts of the blade members 1 and 2 of the scissors and by bows l0 and 11 made from a length of steel band.
  • the bows 10 and 11 have an elongated form as shown and include projections 12 and l3 located at their free end portions.
  • the projections 12 and 13 are formed by cutting away a part of one of the longitudinal edges and located in the extension of the other longitudinal edge of the bows l0 and 11.
  • the length of the projections 12 and 13 is equal to the width of the handle parts of the blade mambers of the scissors.
  • the handle parts include at least one elongated planar face located along the same side of the blade members 1 and 2 as shown.
  • the projections 12 of the bows l0 and 11 are firmly inserted in transverse grooves 14 provided in the outer plane broad side or said elongated planar face of the handle parts.
  • the projections 13 are disposed transversely with respect to the elongated planar faces and are firmly secured on the free ends of the handle parts which, for this purpose, are made thinner by shoulders 15.
  • the projections 12 and 13 are connected along their length with the handle parts by hard soldering or the like.
  • the grasp eyes 4, 5, 6, 7, 10 and 11 each have an elongated form. These eyes are disposed along the elongated planar face of its associated handle part so that the pressure of the fingers necessary for closing the scissors of the invention is applied to the planar faces of the handle parts. That is, this finger pressure is not exclusively taken up by the grasp eyes as is the case in prior art scissors.
  • the elongated planar surface of each grasp eye and the elongated planar face of each associated handle part are parallel with respect to each other and extend for a substantial distance along the length of the grasp eye so that the pressure of the fingers necessary for closing the scissors is applied to the elongated planar faces of the handle part.
  • Scissors comprising:
  • a a pair of blade members each of which has a handle part and a blade part including a cutting edge
  • each said handle part including at least one elongated planar surface
  • two initially separate'grasp eyes each composed of a section of bright material and having an elongated form which includes an elongated planar surface
  • said elongated planar surface and elongated planar face being parallel with respect to each other and extending for a substantial distance along the length of the grasp eye so that the pressure of the fingers necessary for closing the scissors is applied to the elongated planar faces of the handle part.
  • each of the initially separate grasp eyes consists of a section of tube composed of bright-drawn material.
  • Scissors comprisingz' a pair of blade members each of which has a handle part and a blade part including a cutting edge
  • each said handle part including at least one elongated planar face located along the same side of the blade member as the cutting edge
  • two initially separate grasp eyes each composed of a section of bright material and having an elongated form including an elongated planar surface
  • each of the initially separate grasp eyes consists of a section of tube composed of bright-drawn material.
  • a method of forming scissors consisting essentially of:
  • grasp eyes are formed from a section of bright material and said bright material section is bent to the desired shape including an oblong straight circumferential portion.
