  • - zur Handhabung des Hammers dienenden Handgriffen (6a, 6b, 6c);
  • - einem den Motor (3) und das Kurbelgetriebe umgebenden Hammergehäu­ se (2), und
  • - einer gegen das Hammergehäuse (2) abgefederten, die Handgriffe (6a, 6b, 6e) tragenden Schutzhaube (5), die - bezogen auf die aufrechte Gebrauchs­ stellung des Hammers - das Hammergetriebe zumindest oben, seitlich und zu­ mindest frontal auf der der Bedienungsperson zugewandten Seite jeweils mit Abstand verkleidet, wobei die Schutzhaube (5) und das Hammergehäuse (2) re­ lativ zueinander und parallel zur Längsachse des Hammers durch ein Parallel­ lenkersystem (8a, 8b, 9a, 9b) geführt sind;
dadurch gekennzeichnet, daß zwischen einer oberen Wandung der Schutzhaube (5) und dem Hammergehäuse (2) ein Federelement (19) angeord­ net ist, das aus zwei bogenförmig gekrümmten, mit ihren konkaven Seiten ein­ ander zugewandten Blattfedern (20a, 20b) besteht.1. Motorized hammer, with
  • - A hammer mechanism driven by a motor ( 3 ) via a crank mechanism;
  • - Handles for handling the hammer ( 6 a, 6 b, 6 c);
  • - A surrounding the engine ( 3 ) and the crank mechanism hammer housing ( 2 ), and
  • - A against the hammer housing ( 2 ) sprung, the handles ( 6 a, 6 b, 6 e) carrying protective hood ( 5 ), which - based on the upright use position of the hammer - the hammer mechanism at least above, laterally and at least frontally the side facing the operator each with a distance, the protective hood ( 5 ) and the hammer housing ( 2 ) re relatively to each other and parallel to the longitudinal axis of the hammer through a parallel handlebar system ( 8 a, 8 b, 9 a, 9 b) are guided ;
characterized in that between an upper wall of the protective hood ( 5 ) and the hammer housing ( 2 ) a spring element ( 19 ) is angeord net, which consists of two arcuate, with their concave sides facing one another leaf springs ( 20 a, 20 b) . 2.
