Sawtooth 513 is done imaging saw sword sharp-pointed front end (Fig. 6 C) like that.To form a plurality of such sawtooth 513 with circular arc double wedge 424b uniform distances.Therefore, if lockplate 51 forwards moves in depressed part 327 is installed, then shown in Fig. 6 B, between the low ebb between the leading section of each sawtooth 513 embedding circular arc double wedge 424b.Like this, stop moving of tooth bar 424.
Latch-release member 52 comprises: square column sheet 521 connects and to penetrate the square hole 329a (Fig. 4, Fig. 5) on the depressed part 329 of dodging that is arranged on base plate 32; Flange 522 is with the upper end formation one of this square column sheet 521; And operation projection 523, be arranged to above this flange 522 outstanding upward.Dodging the size of the square hole 329a of depressed part 329 sets for: overlook identical substantially with the square hole 512 of lockplate 51.
The size of flange 522 is set for bigger than the square hole 329a that dodges depressed part 329, like this, even square column sheet 521 from top embedding square hole 329a, also can prevent to come off downwards.Shown in Fig. 6 B, 6C, operation projection 523 sees that from the side (from left and right directions) forms the shape of right-angle triangle, and a side forms dip plane 523a in the back.
Shown in Fig. 6 B, when the surface level of latch-release member 52 was set in lower position S4 (Fig. 2 A), operation projection 523 was because of being positioned at the bottom from focusing in the square hole 512, and thus, lockplate 51 is forwards moved by the throw-on pressure of volute spring 53.Like this, the rear edge portion of square hole 512 is connected to the upper edge of this operation projection 523, and the circular arc double wedge 424b of sawtooth 513 and tooth bar 424 engagement.
Relative therewith, shown in Fig. 1 C, carton 30 is extracted out from framework 11, is placed on the table top T of regulation, and when square column sheet 521 bore from the counter-force of base T1 or table top T, latch-release member 52 was resisted the described throw-on pressure of volute springs 53 and raise.Like this, the dip plane 523a of operation projection 523 rearward pressure-locks the rear edge portion of the square hole 512 of plate 51, causes lockplate 51 to retreat thus, shown in Fig. 6 C, and the engagement of the circular arc double wedge 424b of releasing and sawtooth 513.
Fig. 7 A, 7B are the VII-VII line cut-open views of Fig. 6 A that is used to illustrate the effect of locking mechanism 50, be respectively: Fig. 7 A represents that the surface level of latch-release member 52 is set in the state of lower position S4, and Fig. 7 B represents that the surface level of latch-release member 52 is set in the state of top position S5.In addition, identical (X is left and right directions (X: left ,+X: right-hand) to the situation of the direction represented of the X among Fig. 7 A, the 7B and Y and Fig. 1, and Y is fore-and-aft direction (Y: the place ahead ,+Y: the rear)).
At first, when carton 30 is contained on the framework 11, and carton 30 from framework 11 pull out the back, to be placed on table top T before going up during, shown in Fig. 7 A, latch-release member 52 is because of deadweight, surface level is set in lower position S4.At this moment, the upper edge of only operating projection 523 becomes the state in the square hole 512 of imbedding lockplate 51.Therefore, lockplate 51 is subjected to the throw-on pressure of volute spring 53, becomes the state that forwards moves, and blocks the upper end of operation projection 523 up to the rear edge portion of square hole 512.
Under this state, the sawtooth 513 of lockplate 51 meshes with the circular arc double wedge 424b of tooth bar 424, and like this, the tooth bar 424 of right-hand width adjustment guide 422 is locked, and direction (direction vertical with the paper of Fig. 7 A) moves to the left and right.Therefore, in case the width adjustment guide 42 that is positioned is during becoming pack into framework 11 or the half shown in Fig. 2 A, the 2B and doing well, shown in Fig. 1 C, carton 30 from framework 11 extract out, during be placed into table top T and go up, with carton 30 from table top T mention, during the framework 11 of packing into, and carton 30 packed into after the framework 11, width adjustment guide 42 can not move.
Therefore, in case the width adjustment guide 42 of location can relatively vibration during framework 11 mounting or dismounting operations and the inertial force when carrying etc. cause and move because of carton 30, then under carton 30 is packed the state of framework 11 into, can make width adjustment guide 42 keep positioning states reliably to prevent rough sledding as displacement etc.
