Abstract

Selon l'invention, une patte de fixation en forme de L est fixée sur l'un des côtés d'une batterie portable (40). Une branche de cette patte, qui fait saillie vers l'extérieur sur le côté de la batterie, comporte une paire de logements (46 & 48) conçus, l'un pour délivrer une énergie d'alimentation et/ou de réalimentation à un dispositif externe alimenté en courant continu et l'autre pour délivrer une énergie de réalimentation à la batterie portable. Une housse de transport (10) fabriquée en tissu épais comporte une pluralité de compartiments destinés à divers articles. La batterie, munie de la patte de fixation comportant les logements, est montée, de préférence en permanence, dans un compartiment interne qui doit être ouvert pour donner accès aux logements en vue de l'insertion et du retrait de prises (64). La batterie est positionnée dans une poche ayant un bord supérieur affleurant la branche de la patte de fixation comportant les logements et une partie supérieure de la batterie dépasse au-dessus de ladite poche.
