Then, by between the 1st snap-latch piece 61 of engagement pin 79 that holds casing 8 and dwang 27, being formed with d (with reference to Fig. 3) at interval, even dwang 27 also moves towards the place ahead along with forwards pulling out header board 9, owing to can guarantee fully that dwang 27 rotates into the distance of level, so dwang 27 engages with engagement pin 79 reliably.In addition, because between the 1st snap-latch piece 61 and the 2nd snap-latch piece 63, be formed with the interval p bigger between the 1st snap-latch piece 62 and the 2nd snap-latch piece 64 than the diameter of

engagement pin

79,80, so dwang 27 is engaged on the engagement pin 79 easily, the 1st snap-latch piece 61 of the bar 27 that is difficult to rotate does not engage with the engagement pin 79 that holds casing 8 and only the action that is drawn out of header board 9 is bad.

When the engagement pin 79 that holds casing 8 engages with the 1st snap-latch piece 61 of dwang 27, become the header board 9 and the state that holds casing 8 bindings of face side, hold the move foreign side (front plate side) that pulled into face side of casing 8 with header board 9.At this moment, mobile unit 46 is along with holding moving of casing 8, with the lower surface sliding-contact of member to undertake 89 on one side to face side move on one side.

And when mobile unit 46 pulled into face side, shown in Fig. 6 and Figure 10 (b), the rear end side of mobile unit 46 was left member to undertake 89, because the power that applies of leaf spring 50, mobile unit 46 rotates into heeling condition.So, be formed on the inclined plane 46b on the leading section of mobile unit 46 and holding section 85 butts of linking part 23.At this moment, the inclined plane 46b inclination predetermined angular θ of mobile unit 46, thus even having, mobile unit 46 makes error etc., inclined plane 46b also can be closely and holding section 85 butts.

Be described more specifically this inclined plane 46b, when if the top at 46b place, this inclined plane is identical with following distance with respect to pivot 46a, when then making mobile unit 46 form a little longerly owing to the making error, the bottom on inclined plane 46 abuts to the upper surface of holding section 85 and can not engage sometimes.In addition, when making mobile unit 46 form shortlyer slightly owing to the making error, any surface from the top to the bottom of inclined plane 46b all can not touch holding section 85 sometimes.Therefore, at inclined plane 46b place, so that the distance of the top of inclined plane 46b and pivot 46a forms mobile unit 46 than the mode of the distance of the bottom of inclined plane 46b and the pivot 46a predetermined angular θ ground that tilts, also can be constrained to and hold casing 8 it can not rocked with respect to header board 9 even on mobile unit 46, have a little making error.

In addition, by by leaf spring 50 all the time to mobile unit 46 to the direction application of force that makes its rotation, the action that can do one's utmost to reduce mobile unit 46 is bad, and can make holding section 85 butts of mobile unit 46 and linking part 23 really.

By the 1st snap-latch piece 61 and engagement pin 79 butts, and holding section 85 butts of the inclined plane 46b of mobile unit 46 and linking part 23, thereby the relatively moving on fore-and-aft direction of casing 8 with respect to header board 9 held in restriction.Therefore, eliminated and held casing 8 rocking, having eliminated and when holding, hold the situation that casing 8 collides header board 9 with respect to header board 9.

In addition, header board 9 with hold casing 8 and become connecting state after, because mobile unit 46 is rotated with holding section 85 butts of linking part 23, header board 9 is restricted with the relatively moving on fore-and-aft direction of holding casing 8, so can successfully not carry out header board 9 and the binding of holding casing 8 because of the restriction of mobile unit 46 causes obstacle in the binding of dwang 27 and the engagement pin 79 that holds casing 8.

As shown in Figure 7, at the header board 9 of face side when holding casing 8 and be drawn out, the header board 10 of rear side becomes and holds the state that casing 8 separates, be not left with holding casing 8 interlocks, therefore can block the rear side of kitchen platform 1 by this panel 10, not only do not cause recess and improve outward appearance, and the operation of pulling out of face side does not have inharmonious sense yet in the rear side of kitchen platform 1.And can prevent to enter dust etc.So by the so simple structure of

dwang

27,28 and

engagement pin

79,80, can realize along with the operation of pulling out, hold being drawn out being dynamically connected certainly and holding in casing 8 and the

header board

9,10 and not being drawn out separating automatically of a side of a side in casing 8 and the

header board

9,10

header board

9,10.

As shown in Figure 7, when the header board 9 of face side pulled into assigned position or overshoot position, the main roller 52 that is disposed at the top breaks away from the supporting rail 20 of top, and auxiliary wheel 55 mountings below almost meanwhile being disposed at are to supporting rail 19 upper surfaces that are disposed at the below.At this moment, by the main roller 51 and the auxiliary wheel 55 that are disposed at the below, hold casing 8 in two bearing position supportings of the front side of supporting rail 19 bearing position and rear side bearing position.

In addition, as shown in Figure 7, holding that casing 8 is pulled out significantly to face side or when holding casing 8 and being accommodated significantly, be disposed at the mobile unit 47 of holding casing 8 rear side and member to undertake 89 butts that are located at face side, but because to rotate with member to undertake 89 butts, mobile unit 47 becomes level, so the mobile unit 47 of rear side can waltz through the below of the member to undertake 89 of face side.

As shown in Figure 8, when the handle 35 of the header board 10 of pulling out rear side to back side direction (front plate side), dwang 28 actions of the rear side on the supporting rail 20 above being located at, become the header board 10 of rear side and hold the state that casing 8 is connected, can pull out to back side direction (front plate side), when being pulled out to assigned position or surpassing assigned position, the main roller 51 that is disposed at the below breaks away from the supporting rail 19 of below, and auxiliary wheel 56 mountings above being disposed at are to the upper surface of the supporting rail 20 that is disposed at the top.At this moment, at two bearing position places of front side bearing position and rear side bearing position, will hold the supporting rail 20 that casing 8 is supported on the top by the main roller 52 that is disposed at the top and auxiliary wheel 56.

When holding casing 8 and being pulled out significantly, promptly have when being pulled out to the afore mentioned rules position or surpassing the amount of pulling out of afore mentioned rules position, because hold outside the casing 8 in the supporting of the bearing position place of front side by

main roller

51,52, move on the supporting

rail

19,20 by

auxiliary wheel

55,56, can switching to also in the wings, the bearing position upper support of side holds casing 8, so can pull out drawer 7 significantly, hold casing 8 and open and more also can stably support this and hold casing 8 even make.Therefore, no matter contents such as tableware all take out contents from both sides easily near holding face side in the casing 8 and which side of rear side.

Describe accommodating the dual directional drawer 7 that holds casing 8, as shown in Figure 9, under the state that drawer 7 has been drawn out, when the user towards receipt side during to the handle 34 of the header board 9 that pushes away face side, under the state that engagement pin 79 that holds casing 8 and dwang 27 are connected, hold casing 8 with header board 9 towards receipt side to moving.At this moment, by by the relatively moving of limiting part restriction header board 9 and the fore-and-aft direction that holds casing 8, so header board 9 with hold casing 8 and can not collide.Then, the inclined plane of the dip member 45 of the end of the supporting rail 20 that linking along header board 10 of the main roller 52 of top with rear side roll on and mounting to the upper surface of the supporting rail 20 of top.So the auxiliary wheel 55 of top leaves the supporting rail 19 of below, hold on the supporting rail 20 that casing 8 only depends on supporting rail 19 that

main roller

51,52 is supported on the top and below.

Shown in Fig. 9 and Figure 10 (c), when header board 9 further is pushed into, be formed at the arc sections 46c of inboard of mobile unit 46 and the conical surface 89a butt of member to undertake 89, mobile unit 46 rotates into becomes level.Then, the inclined plane 46b of mobile unit 46 leaves the holding section 85 of linking part 23, has removed the restriction that relatively move of storage case body 8 with the fore-and-aft direction of header board 9.

Then, near the separation point position of dwang 27 and engagement pin 79, abutting part 42 on the supporting rail 19 below being located at and butt sheet 40 butts that are formed on the air damper 36, because the active force of air damper 36, header board 9, supporting rail 19 and the translational speed of holding casing 8 all are decelerated.After holding casing 8 deceleration just, dwang 27 rotation with fastening sheet 69 butts, and dwang 27 is separated with the engagement pin 79 that holds casing 8.Owing to holding under the state that casing 8 fully slowed down, dwang 27 separates from the engagement pin 79 that holds casing 8, flies out from rear side so hold casing 8 can not cross accommodated position, stably is disposed at accommodated position.

So when holding casing 8 and be received, before header board 9 and the connecting state that holds casing 8 are disengaged, mobile unit 46 is thrown off from the holding section 85 of linking part 23, and removed the restriction that relatively moves of storage case body 8 and the fore-and-aft direction of header board 9, thereby can successfully not carry out header board 9 and separate (releasing of connecting state) of holding casing 8 owing to the restriction of mobile unit 46 brings obstacle to the connecting state of removing the engaging of dwang 27 and the engagement pin 79 that holds casing 8, promptly casing 8 and header board 9 being held in releasing.

In addition, slide easily on supporting rail 19 and on fore-and-aft direction by main roller 51 and auxiliary wheel 55 mountings, also can hold the moving of fore-and-aft direction of casing 8 by the 1st snap-latch piece 61 of dwang 27 and mobile unit 46 restrictions even hold casing 8.Therefore, promoting header board 9 during closing drawers 7, by the holding section 85 pushing mobile unit 46 of linking part 23, header board 9 is not collided hold casing 8 and positively make hold casing 8 towards receipt side to moving.
