Japanese Patent JP3150549

B2

PURPOSE: To improve connecting strength, and facilitate connecting work by connecting both side parts of a back member whose back face side is freely openable and closable to side members from its inside by at least an upper connecting means among a lower connecting means and the upper connecting means.
CONSTITUTION: A front member 7 is connected to front receiving tools 3 of a pair of side members 1 by front member connecting tools 8 so as to be freely mountable and demountable, and a lower end part of a back member 11 is connected to rear receiving tools 4 so as to be freely mountable and demountable. That is, a pair of lower connecting tools 15 are installed in width directional both end parts of a lower part of a front face plate 13 of the back member 11, and its locking holes 15b are engaged with a pair of pins 4b of the rear receiving tools 4, and fastening bolts 22 are inserted into through holes 12a of both side upper parts of a frame body 12, and are screw-fitted to nuts 10 embedded in the side members 1. In that case, when a lower fastener 14c of a back face member 14 is opened, its fastening work is facilitated. As a result, a load applied to the back member 11 is dispersed to the lower connecting tools 15 and the fastening bolts 22, and an assembling condition can be reliably maintained.
