Definitions

  • the present invention relates to a portable power tool provided with a hanging hook for hanging a user on a waist belt or the like.
  • Japanese Patent Publication No. 2002-254358 discloses a portable power tool having a hanging hook.
  • a battery pack is attached to a large battery holder formed at the lower end of the handgrip, and a hanging hook is rotatably held by a bearing formed in a part of the large battery holder.
  • a hanging hook is held at an arbitrary angle around the axis, and the power tool can be hung on the waist belt at an angle desired by the user.
  • the hanging hook protrudes greatly from the width of the battery holder or the width of the battery pack in any angle position. For this reason, the provision of the hanging hooks not only increases the overall width of the power tool, but also causes the tool hook to hit the ground first and be damaged if the power tool falls.
  • a portable power tool with a hanging hook includes a housing containing a motor.
  • the housing includes a chuck for holding a tool bit driven by a motor.
  • a hand grip to be gripped by the user extends from the housing, and a wide battery holder is formed at one end of the hand grip opposite the housing.
  • This battery holder holds a battery pack that energizes the motor, and has a width and length along a direction intersecting the axis of the handgrip. It is less than the width of the battery holder.
  • the hanging hook is for holding the power tool and is supported by the bearing.
  • the bearing is formed in the vicinity of one end in the length direction of the wide battery holder and pivotally supports the hanging hook, so that the hanging hook can rotate around an axis along the width direction of the battery holder, It is selectively clicked to one of several angular positions around this axis.
  • a feature of the present invention is that the entire hanging hook is accommodated within the width of the battery holder, regardless of the angle at which the hanging hook is held. Due to this feature, despite the addition of the hanging hook, the width of the entire power tool does not increase and the power tool can be finished compactly. The advantage is given that the hook alone can be prevented from hitting the ground first and the hanging hook can be protected from breakage.
  • the plurality of angular positions include a rest position where the hanging hook is locked on the battery holder.
  • This rest position is used when the power tool is not used, and the power tool can be stored so that the hanging hook is not in the way.
  • the tool battery holder is moved from the rest position to another position. At this time, the possibility that the power tool is accidentally dropped is the highest. Even if the power tool falls and the tool battery holder collides with the ground first, the tool battery holder is locked on the battery holder in the rest position, so the impact Concentration only on the battery holder can be avoided, and damage to the tool battery holder can be prevented.
  • the bearing socket is formed at one end in the longitudinal direction of the battery holder above the battery pack along the axial direction of the hand grip, so that the hanging hook does not interfere with the battery pack. .
  • the hanging hook is composed of a shaft portion and an arm extending from one end of the shaft portion, and the bearing accommodates the shaft portion and clicks together with the shaft portion. Configure the mechanism. With this click mechanism, the hanging hook cannot be disengaged from the bearing socket's force (and can be click-moved from one angle position to another angle position). With this feature, the hanging hook can move freely without removing the hanging hook from the bearing, but when the hanging hook stops at a predetermined angular position.
  • the battery holder can be positioned at the outermost position within the width direction of the battery holder.
  • FIG. 1 is a perspective view showing a portable power tool according to a preferred embodiment of the present invention.
  • FIG. 2 is a front view for explaining the operation of a hanging hook provided in the power tool.
  • Fig. 3 is a partially cutaway top view of the power tool.

Abstract

L'invention concerne un outil électrique portatif à crochet de suspension, qui permet d'accrocher l'outil à une ceinture autour de la taille, etc. Un porte-batterie recevant un bloc-batterie est prévu à l'extrémité inférieure d'une poignée de l'outil. Le crochet est fixés sur l'outil de sorte qu'il puisse tourner autour d'un arbre support. La fixation est réalisée à travers un palier situé au voisinage du porte-batterie. Le crochet peut être déplacé sélectivement au moyen de cliquets vers une série de positions angulaires autour de l'arbre. Le crochet est dans les limites de la largeur du porte-batterie, quelle que soit la position angulaire dans laquelle il est maintenu. En conséquence, si l'outil est lâché, il ne tombe pas au sol le crochet en premier, et on protège ainsi le crochet contre les risques de rupture.
