The specific embodiment

In each accompanying drawing for omitting the view of a complete drawer for the purpose of clear, because only those devices are important within the scope of the invention, promptly a panel 1 can be fixed on each side frame 2 of a drawer and can vertically adjust at least by means of them.

On described panel 1, on the inner face that is opposite to each side frame 2 (drawer has two such side frames that are parallel to each other and extend certainly), be screwed each fixed head 3, each fixed head 3 is provided with slotted hole 3a for this reason, can guide hold-down screw by them.Because the slotted hole 3a that exists, also drawer horizontal adjusting panel 1 relatively in addition.

Each fixed head 3 has one and is parallel to the flank 4 that side frame 2 extends.Height Adjustment eccentric wheel 5 of riveted joint makes this Height Adjustment eccentric wheel still can rotate relative to flank 4 on this flank.

Fix a clutch shaft bearing seat 6a on this external described flank 4, preferred riveted joint.Another bearing block 6a is fixedly connected on a folding lever 7, same preferred riveted joint.

Diaxon bearing 6a and 6b interconnect rotationally via each bearing pin 8.

Folding lever 7 is provided with two mutual opposed flank 7a, and they are provided with two mutual hole 7b point-blank.

In the 7b of these holes, embed each end 9a that constitutes bearing pin 9 of the corresponding location of a clamp lever that totally is provided with mark 9.This clamp lever 9 constitutes arciform in an illustrated embodiment.Arciform clamp lever 9 is provided with a hook-shaped bending in its end away from each the end 9a that constitutes bearing pin, and it especially clearly is shown in Fig. 7.

Fig. 7 is equally clear to be illustrated, and has a spacing between the pivot center of each the end 9a that constitutes bearing pin of the pivot center of joint pin 8 and clamp lever 9.

Also be apparent that as Fig. 7, bearing 10 in the zone of side frame 2 of the hook-shaped crooked 9b back side of clamp lever 9 interlocking, wherein this bearing 10 is made of the border of the close panel 1 of a port 11 in side frame 2 in an illustrated embodiment.

Fig. 2 is clear to be illustrated, each side frame 2 in the zone of its fixed head 3 and the end face 2a that also is opposite to a panel 1 like this be provided with one towards the unlimited groove 2b of end face 2a over there.This groove 2b becomes stepped expansion over there and respectively imports inclined-plane 2c at the transitional region internal shaping of part between the part of remaining back of groove 2b bigger, close end face 2a towards end face 2a.

The Height Adjustment eccentric wheel 5 that might will rivet on the flank 4 of fixed head 3 easily and like a cork by such design is inserted in the zone of back of groove 2b.Preferably, the zone of the back of groove 2b has very little tolerance with respect to the part of the Height Adjustment eccentric wheel 5 that is held by this zone, thereby produces as far as possible little height gap here.

A panel 1 forms panel 1 certain pre-assembled state or temporary transient fixing in the face of drawer again then, relatively the front end rib 2a of each side frame 2 has installed described each fixed head 3 and has comprised each Height Adjustment eccentric wheel 5 and clamp lever 9 and folding lever 7 on this panel, respectively clamps simultaneously in the zone of back that eccentric wheel 5 inserts each groove 2b.This as seen from Figure 3 state.

Then in another number of assembling steps, the hook-shaped crooked 9b of clamp lever 9 is inserted in the corresponding port 11 of side frame 2 with hand.This assembling position is shown among Fig. 4.Folding lever 7 is still routed up from side frame 2 significantly in whole described assembling process so far.

By affacting the unshowned spring assembly on the clamp lever 9, it presses to flank 4 all the time with clamp lever 9, can not need hook-shaped crooked 9b is inserted in the port 11 with hand, because crooked in this case 9b embeds in the port 11 in the installation process of described fixed head 3 on side frame 2 automatically.

Corresponding Height Adjustment eccentric wheel 5 also remains come-at-able and therefore can rotate so that adjust the height of panel 1 by a kind of proper implements if necessary.

If panel 1 is correctly located, then two folding levers 7 are forwarded on the mutual opposed side frame 2.Thereby the reliable of panel 1 relative drawer that clamp securely and also produce that produces the front end rib of panel 1 relative each side frame 2 whereby fixed.

In fact folding lever 7 and clamp lever 9 constitute a toggle link, and its 26S Proteasome Structure and Function is known in many technical fields basically.

In the position of this clamping, as shown in Figure 7, clamp lever 9 produces beyond its dead-centre position minutely, thereby prevents opening automatically of folding lever 7 and/or clamp lever 9.In addition, also can be arranged on (unshowned) locking device that works between folding lever 7 and fixed head 3 or the side frame 2 naturally, it is difficult to folding lever 7 or stops its unexpected disengagement, that is routs up.

Be used for panel 1 on the drawer or the stationary device on the front end rib 2a at each side frame 2 of drawer, as shown with describe, comprise can simple inexpensive manufacturing each member.Even also can be fixed on easily and like a cork on the drawer by technical deconditioned personnel at these members this panel 1 after pre-assembling on the panel 1.Can implement the dismounting that may need equally simple and easyly.

Relatively and other change of described embodiment be possible.Point out that bearing block 6a and 6b can make one with fishplate bar 4 or folding lever 7.

Can imagine equally, clamp lever 9 is not arciform, but by a flat material forming, it must be provided with each bearing pin, and they can embed among the corresponding hole 7b of each fishplate bar 7a of folding lever 7.

Described each member also can constitute die casting.

Same bearing 10 also can partly be made of a material that outwards is provided with from side frame 2 on each side frame 2.The hook-shaped crooked 9b that then must correspondingly mate clamp lever 9 in this case where necessary.

Above-mentioned each form of implementation is apparent that, the diversified change of illustrated embodiment is possible and do not need to change basic design principle.

Under any circumstance folding lever 7 advantageously can be constituted plate shape and it is sized to makes this clamp lever when toggle link clamps, cover clamp lever 9 and Height Adjustment eccentric wheel 5, thereby panel 1 in the perimeter of a side plate 2, produce a kind of impression of sealing fixedly the time, as being seen by Fig. 5 and 6.
