FR2846902A3 - Method for fitting magnets into tool handgrip whereby magnets are pressed into recesses prior to coating with plastic moulded plastic layer - Google Patents

Abstract

A method for applying magnets into the handgrip of a tool has the core of the handgrip provided with recesses into which the magnets are pressed. The handgrip is inserted into a mould and a plastic outer coating secures the fitting and provides the grip texture. The outer coating is coloured as selected and the magnets are hidden by the coating.

  TOOL HANDLE INCORPORATING AT LEAST ONE MAGNETIC PART

  The present invention relates to a tool handle which has at least one magnetic part incorporated in it.

  A conventional hand tool such as a screwdriver generally includes a handle and a rod which is fixedly connected to a

  end of the handle. Users hold the handle to tighten or loosen a screw by rotating the rod. Hand tools are always placed randomly on the floor during work and the floor is sometimes messy.

  In some particular work sites, there is not enough room to allow these tools to be placed randomly, so that users

  must return to a box or other each time they change tools.

  It takes time and reduces work efficiency.

  Some handles are fitted with glued magnetic parts. The magnetic parts protrude from the handle and can be detached from the handle under the effect of an impact on the magnetic parts. In addition, the magnetic parts are black and the color is not the same as that of the handle so that this combination is not attractive. The object of the present invention is to provide a handle 20 for a hand tool comprising recesses in the handle for receiving therein.

magnetic pieces.

  More specifically, the subject of the invention is a handle for a hand tool, comprising: - at least one recess defined in an external periphery 25 of the handle and a magnetic piece received in at least one recess, and

  - an external coating mounted on the handle to wrap the handle and the magnetic part.

  According to a second embodiment of the invention, the handle comprises: a threaded rod extending from the handle and at least one magnetic piece connected by thread to the threaded rod, and

  - an external coating mounted on the handle to wrap the handle and the magnetic part.

  According to a third embodiment of the invention, the handle comprises: - a threaded rod extending from the handle and an end cover connected to the threaded rod, the end cover comprising a recess defined at l inside and a magnetic part received in the recess, and - an external coating mounted on the end cover

  to wrap the end cover and the magnetic part.

  Other characteristics, details and advantages of the invention will emerge on reading the description given with reference to the drawings

  attached given by way of example which respectively represent: - Figure 1 shows a male mold and a female mold for manufacturing a handle according to the present invention; - Figure 2 is a sectional view to show that an outer coating is located between the male mold and the female mold of the present invention; - Figure 3 shows another embodiment of a male mold and a female mold for manufacturing the handle of the present invention; - Figure 4 is a sectional view of an outer coating located between the male mold and the female mold of the present invention as illustrated in Figure 3; - Figure 5 is a perspective view of the handle of the present invention; - Figure 6 shows another embodiment of the handle of the present invention; - Figure 7 shows yet another embodiment of the handle of the present invention; - Figure 8 is a sectional view of the handle of the present invention of Figure 7; - Figure 9 shows that the handles according to the invention are attracted at their periphery against a vertical surface, and - Figure 10 shows that the handles according to the invention

  are drawn in their lower part against a horizontal surface.

  Referring to Figures 1 and 2, the handle 40 of a hand tool of the present invention comprises two recesses 20 defined in an outer periphery of the handle 40 and is connected to a male mold 60. A female mold 70 comprises a concavity 80 which receives the handle 40 in

  it and a space is defined between the interior of the concavity 80 and the handle 40.

  A magnetic piece 30 is received in each of the recesses 20. An outer covering 50 is formed by injecting a suitable material into the space and the outer covering 50 is mounted on the handle 40 to wrap the handle 40 and the magnetic piece 30. Through to the outer coating 50, the magnetic parts 30 are protected by the coating

  exterior 50 and the exterior coating 50 may be of the desired color.

  Referring to Figures 3 to 6, the magnetic part referenced 140 may also be located at the bottom of the handle 100. The handle 100 has a threaded rod 101 extending from it and an end cover 120 is connected to the threaded rod 101. A recess 130 is defined

  in the end cover 120 which is received in a concavity 150 defined in a female mold 110 with a space defined between the interior of the concavity 150 and the end cover 120. An external coating 160 is produced in the same way than that described in relation to FIG. 2 so as to wrap the end cover 120 and the magnetic piece 140.

  Referring to Figures 7 and 8, a threaded rod 210 extends from an end surface 220 of the handle 200 and a part

  magnetic plastic 230 is connected by thread to the threaded rod 210.

  Figure 9 shows that the handles can be attached to a substantially vertical metal plate by their magnetic pieces and Figure 10 shows the handles standing on a metal plate

  substantially horizontal thanks to their magnetic parts 230.

  The invention is in no way limited to the exemplary embodiment given solely by way of illustration of the subject of the invention.
