grip from the inside against a front wall of the battery block 12 not shown the battery block 12 is indicated in fig6 and 7 as is generally known wall sections of the battery block 12 project upwards over the received battery the buffers 54 thus engage with the top of the inside of the front wall in order to hold and lock the battery block 12 in this position against the stop portions 28 30 in accordance with fig4 and 5 in the locked position a pin 66 on the inside of the vertical jaw section 52 also engages with a hole 68 see fig1 and 2 which is formed on the upper edge of the front walls of the battery block 12 for shipping purposes the pin 66 is not in contact with the battery rather it should just prevent the lever 50 from slipping up and thus the release of the lock if the lever 42 is pivoted into the open position the second lever 50 also pivots and the buffers 54 pivot over the edge of the battery block 12 as shown in fig6 and 7 fig6 shows a 120 u00b0 pivoting of the lever 42 with respect to the locked position in accordance with fig4 and 5 while fig7 shows a 140 u00b0 pivoting in this final unlocked position the hook section 60 lies on the stop pin 62 fig5 such that further opening is not possible however the pivot position of the second lever 50 is such that the battery can not only be moved out laterally but also upwards the buffers 54 are thus no longer in the way so that the second lever 50 can perform the described pivoting into the unlocked position the ramp.
