Definitions

  • This invention relates to the insertion and withdrawal of drawing pins (thumb tacks).
  • drawing pins are intended to be inserted by thumb pressure and withdrawn with the fingers, it can be beyond comfortable thumb pressure of many persons to insert them into a comparatively hard material and, once inserted, they may be impossible to withdraw with the fingers alone. All kinds of implements not intended for the purpose are therefore employed both to force in and extract drawing pins, with consequent inconvenience to and sometimes risk to the hands of the users and the possibility that pins will become bent and unusable. It is an object of this invention to make the insertion and withdrawal of drawing pins easier and safer with less likelihood of damage to the pins.
  • the present invention provides a tool for inserting and extracting drawing pins, comprising a hollow barrel, and a tool head fixed on one end of the barrel having a recess to receive and temporarily retain the head of a drawing pin, with the shank of the pin projecting out axially therefrom, while the pin is inserted by axial pressure of the tool, the tool head being disengageable from the pin head after the pin is inserted, said recess being defined in part by an inwardly directed thin radial flange forming the extreme axial end face of the tool head behind which the pin head is engaged and which surrounds or is formed with an aperture that allows both the pin head to be inserted into and removed from the recess and also the emergence of the pin shank to project axially.
  • a small magnet is provided at the bottom of the tool recess, to retain the head of a pin during insertion or after withdrawal.
  • the tool shown in Figures 1 to 3 of the drawings has a hollow cylindrical barrel 10 of plastics material with circular metal end closures 11, 12 the end closure 11 being a tool head fixed to the barrel 10 while the end closure 12 is a removable cap that gives access to the interior of the barrel which is used as a container for drawing pins.
  • the tool head 11 is comparatively deep axially and is formed with a central circular axial recess 13 in its exterior end face which recess is undercut, as at 14, the mouth of the recess being formed by a radially inwardly directed retaining flange 15 that is comparatively sharp-edged at its inner periphery, as at 16.
  • the circular entry hole 17 surrounded by the flange 15 is large enough in diameter to pass the head of a drawing pin and the undercut 14 is deep enough axially to allow part of the peripheral margin of the pin head to be then shifted laterally into it very readily.
  • a central circular well 18 is formed into which is fixed a small permanent magnet 20 (not shown in Figure 3).
  • the head of a drawing pin is placed in the recess 13 where it will be retained by the magnet with the pin portion protruding from the head of the tool as at 19.
  • the drawing pin can then easily be pushed into the material intended to receive it by axial pressure of the tool and when the pin is inserted the tool can be disengaged from its head and removed.
  • the tool is replaced with the recess 13 covering the head of the pin and the tool is shifted slightly laterally to engage a portion of the peripheral margin of the pin head behind the flange 15. The pin can then be easily withdrawn by a pull on the tool.
  • Figure 4 shows a modified arrangement as just described in which the end closure or head 21 on the tool barrel 22 is of reduced cross-section so that the whole tool in this instance becomes substantially bottle-shaped.
  • the inwardly-directed retaining flange 23 on the tool head 21 and the rim of the tool head bearing the flange now have a sector of somewhat over 90° cut out, as at 24, so that the pin head can be inserted and removed laterally through the gap 25 thus provided.
  • the circular aperture in the end face of the tool head is substantially unnecessary because the apex of the sectoral cut-out 24 is able to accommodate passage of the pin shank.
  • Suitable materials for the embodiment of Figure 4 are A.B.S. plastics (QE 1092) for the barrel 22 and the end cap 26, and any of glass-fibre-reinforced nylon, acetal polymer M90-04 and polycarbonate plastics for the tool head 21.
  • a particular feature of the embodiment of Figure 4 is that the tool head being in the form of a reduced nose of the tool, with a diameter only slightly greater than that of a drawing pin head, enables the user to insert drawing pins with greater positional precision, as compared with the case of a tool with an end much wider than the drawing pin head which makes it difficult or impossible for the user to see the place where the pin is to be inserted.
  • the barrel can be extended to accommodate a greater supply of drawing pins - 100 pins may be a convenient number and the barrel can easily be made large enough to receive that number.
  • the removable end cap 12 or 26 can be domed, if desired, for more comfort to the user's hand when pushing on the tool.
