  • the mechanical interface is preferably reached according form fit, magnetic holder, Velcro or traction.
  • the electrical contact is achieved, for example, by a plug / Steckerauf entnme- training.
  • all charging voltages of the accumulator-operated tools 6, 7, 8 and 9 provided in the holder receptacles 5 are preferably generated by the charging station 10. Accordingly, a contact is required in total for each charging voltage, in addition a contact for Ground.
  • the charging station 10 provides only one charging voltage (preferably the highest charging voltage of the tools to be accommodated in the mounting receptacles 5).
  • the possibly required lower charging voltage is generated, for example by a DC-DC converter.
  • a plurality of electrical interfaces are provided, in particular for the case that recordings in the support 5 tools are to be recorded with different charging voltages.
  • FIG. 16 A further embodiment is shown in FIG. 16. This is based first on the first embodiment according to FIGS. 1 to 6. In contrast to this, however, as shown in FIG. 16, the charging station 10 can be removed from the case 1 on further contacting of the inside bottom charging contacts 12. For this purpose, a unilaterally to the side wall 14 toward open receptacle 43 is provided in the intermediate space 16.
  • This receptacle 43 is provided in the insertion direction with a depth which allows the charging station 10 to receive preferably completely in the receptacle 43.
  • the receptacle 43 is an integral part of the case bottom part 2.
  • the receptacle 43 is designed like a drawer.
  • the charging station 10 is secured in assignment position in the receptacle 43 against accidental falling out or the like, this for example zufol- ge of a positive connection, a magnetic holder or a frictional connection.
  • the arrangement of two resilient elements 44 which clamp the charging station 10 in the receiving position and hold frictionally.
  • the charging cable 45 provided between the charging station 10 and the charging contacts 12 is selected in terms of length such that it is possible to remove and preferably place the charging station 10 next to the case 1, possibly on a common storage surface.
  • a length of the charging cable 45 of preferably 0.5 to 3 meters, more preferably 1 to 2 meters is given.
  • the power cord portion of the power cord 11 between the charging station 10 and power plug 46 is comparatively short, at least only provided with a length that a network connection of the charging station 10 in the near in the on 43 does not allow me to hold the usual position of power outlets. Accordingly, the connection of the charging station 10 to the household power supply network necessarily the removal of the charging station 10 from the receptacle 43 is required to release about this length reserves.
  • the receptacle 43 in particular in the design thereof as a drawer or the like, may contain other elements, such as tools or consumables. All disclosed features are essential to the invention.
  • the disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.

Abstract

L'invention concerne d'abord une valise (1), comprenant une partie inférieure (2) et un couvercle (3), pourvue de rangements (5) formés dans la partie inférieure (2) et destinés à des outils (6, 7, 8, 9) qui fonctionnent avec des accumulateurs et comprennent une zone-poignée. La présente invention concerne également à une station de charge (10) servant à charger les accumulateurs des outils (6, 7, 8, 9) se trouvant dans les rangements (5) et équipée en outre d'un cordon secteur (11). Pour obtenir une valise offrant une utilisation commode pour des outils fonctionnant avec des accumulateurs, le rangement (5) est composé d'une ou de plusieurs parties en saillie détachées (33) qui sont ancrées dans la partie inférieure (2) et réalisent une interaction de maintien avec l'outil (6, 7, 8, 9) dans une petite zone par rapport à la zone-poignée. La présente invention concerne en outre d'autres pièces rajoutées (également indépendantes). La présente invention concerne en outre un dispositif de maintien portable pour des outils fonctionnant avec des accumulateurs (6, 7, 8, 9). Pour perfectionner un dispositif de maintien du type en question, il est proposé que les rangements (5) soient prévus pour un ou plusieurs outils (6, 7, 8, 9), que le dispositif de maintien (24) comprenne une station de charge (10) et une fiche secteur (46) et qu'il y ait en outre une poignée de transport (23).
