Relationship between large subject matter areas

B25G covers handle constructions relating to hand tools, i.e. tools without power-drive means.

B25B covers wrenches, pliers, spanners and screwdrivers in detail, but all handle related features are to be found in specific places of B25G, such as: B25G 1/025, B25G 1/043, B25G 1/063, B25G 1/085 or B25G 1/105.

A47L 13/00 relates to scrapers and mops (i.e. cleaning devices).

B62K 21/00 cover cycles handles. Ski sticks can be found in A63C 11/22.

Tattoo devices are in A61M 37/00.

Knives related details are in B26B 21/52.

A47J 45/06 cover handles for cookware.

F24C 15/02 cover handles for ovens.

F25D 23/02 cover handles for fridges.

F16B 7/1427 covers telescopic rods/handles.

F16B 7/04 relates to general clamps for rods.

B26B relates to hand cutting tools, such as knives, scissors, axes.

B25D 1/00 and B25D 3/00 relate to hammers and chisels.

A01B covers soil working implements (i.e. agriculture, forestry).

A47G covers table ware (i.e. forks).

A63B covers sports articles (i.e. golf clubs, rackets, etc.).

B29C covers general moulding, coating, etc.

E04F covers devices for finishing works on buildings.

Definition statement
This subclass/group covers:

  • Handles for rotary tools with additional levers, e.g. for increasing torque;
  • Handles for screwdrivers, wrenches or spanners with additional levers, e.g. for increasing torque;
  • Shock-absorbing means;
  • Flexible handles;
  • Telescopic; extensible; sectional handles;
  • Handles reversible or adjustable for position;
  • Handles with provision for storing tool elements;
  • handles characterised by material or shape.

Special rules of classification within this group

Unless having an exclusively specified use (e.g. golf clubs handles), all handle constructions that are mentioned to be suitable for a tool are classified in this group.

Attaching handles to the implements
Definition statement
This subclass/group covers:
  • Socket, tang, or like fixings;
  • Fixings with detachable or separate socket pieces;
  • Fixings with multiple socket, e.g. T-socket;
  • Fixings with dovetail of other groove;
  • Fixings with elastic, taper, or other self-grip socket or tang;
  • Locking and securing devices;
  • Fixings by pressing the handle on the implements; using cement or molten metal, e.g. casting, moulding, by welding or the like;
  • Fixings using lap joints; riveted, screwed, or like joints;
  • Hinged, pivoted, swivelling, or folding joints.
