Description

Have and prevent the cabinet of withdrawing device simultaneously

Technical field

The present invention relates to a kind of cabinet with multi-layer drawers.Cabinet of the present invention is meant the cupboard of broad sense, comprises laterally very wide cabinet, also comprises and the incorporate multi-layer drawers group of desk.

Background technology

Have in this class on the cabinet of multi-layer drawers, if extract two drawers simultaneously out, then cabinet becomes unstable, increases the danger of tumbling greatly.For preventing that cabinet from tumbling, a kind of safety device is installed thereon, after extracting a drawer out, assurance can not be extracted other drawer out.

Yet only this not enough, in all cases because the situation of extracting two drawers simultaneously out is still arranged because of carelessness.The design of safety device in the past can not prevent to extract out simultaneously two drawers.The relevant structure of while withdrawing device that prevents is disclosed in: the spy opens flat 10-179290 communique, and the spy opens flat 11-22271 communique, and the spy opens flat 10-205191 communique.No. three communique and the 1st, 2 different feature have been to use the wire cable.

Yet number of spare parts is many in the structure that above-mentioned communique is announced, assembling procedure is long, and built-up time is long, and assembling back reliable in action is not high yet.

Summary of the invention

Therefore, purpose of the present invention at first provides a kind of cabinet that prevents that drawer from extracting out simultaneously.

Secondly, another purpose of the present invention provides the cabinet of a kind of simple and convenient assembly, reliable in action.

In view of above purpose, according to one aspect of the present invention, provide a kind of cabinet that multi-layer drawers is arranged, this cabinet comprises:

Be arranged on the drawer side guiding parts on each drawer, this drawer side guiding parts comprises the block with rod unit or tipper;

The pillar that moves up and down with respect to this physical efficiency of cabinet;

Pillar side guiding parts, this pillar side guiding parts comprises block or the rod unit with tipper, be arranged on the pillar and corresponding with each drawer side guiding parts, when drawer is pulled out, connect also and can move to a stop position to pillar from common position with drawer side guiding parts, on this stop position, can make the drawer of not pulling out remain on its retrieving position, but when pushing back the drawer of pulling out, also can cooperate and make pillar be returned to initial common position with drawer side guiding parts;

Maintaining body is locked in this position to the pillar that moves to stop position, and unclamps locking in that pillar is returned under the effect of certain force of initial common position;

Connector, with the corresponding setting of pillar side guiding parts, have one and make a concession parts and a limiting part, these yielding parts have cam part, this is made a concession parts and cooperates and upwards yielding with drawer side guiding parts when drawer side guiding parts cooperates with pillar side guiding parts, this limiting part be positioned at make a concession the parts top and with make a concession parts by being connected to equidirectional, the adjacent drawer above the restriction moves to pull-out direction; And the connector that has moved to the top can homing by the power of conducting oneself with dignity or add thereon.

When extracting any one drawer out, the drawer side guiding parts that is arranged on this drawer cooperates with pillar side guiding parts on being arranged on pillar, makes pillar be moved toward stop position.The pillar that is in this position is locked by maintaining body, so can not extract other drawer again out.

When also wanting to extract drawer out again, drawer side guiding parts with make a concession parts and cooperate after, the yielding parts are made a concession upward.The limiting part of interlock also is moved upward, and this limiting part that is moved upward cooperates with this upside drawer, and draw out operation is stopped when extracting the drawer of above-mentioned drawer upside out.This drawer that stops to extract out (upside drawer) is because its drawer side guiding parts cooperates with pillar side guiding parts, and pillar can not move up and down.Therefore the draw out operation pillar that is accompanied by the downside drawer can not move, consequently two drawer (perhaps almost simultaneously) extractions simultaneously.

For example in five layers of cabinet, if above-mentioned upside drawer is the drawer of the superiors, the downside drawer is from last several second layer drawers, that is to say, make a concession the parts design from number second layer drawer, limiting part designs on the drawer of the superiors, thereby the two-layer drawer of going up most of dangerous maximum (almost simultaneously) extraction simultaneously that prevented to tumble, and has improved security.Certainly also be applicable to other drawers, all drawer all is suitable for.

In addition, above-mentioned connector also can be that move the below in the opposite direction, in this case, and must an afterburning upward augmentor.In addition, action effect is the same with said apparatus.

In addition, connector also can be arranged on a pair of drawer of multi-layer drawers all of its neighbor, can effectively prevent cabinet owing to do not note and the accident of overturning.

Have in the cabinet that prevents the while withdrawing device above-mentioned, drawer side guiding parts is the rod unit that protrudes in the drawer side, and pillar side guiding parts is the guide pad that has the tipper that guides described rod unit.Make a concession parts and limiting part and be installed on this guide pad, they move with respect to this guide pad easy on and off in prescribed limit, and interconnect with the yielding parts and the limiting part of pitman with a connector.

Can remain on the guide pad because of making a concession parts and limiting part, and with respect to guide pad within the specific limits easy on and off move, when being assembled into before the cabinet body, give earlier that to be assembled into guide pad be on the pillar side guiding parts making a concession parts and limiting part, this assembly is refilled on the pillar.And then, since make a concession parts and limiting part with respect to guide pad within the specific limits easy on and off move, after installing on the pillar, stride across yielding parts and limiting part between the guide pad of adjacency to above-mentioned each assembly, assemble by the insertion pitman.Body of pillar after assembling is like this refilled on the cabinet body, and assembling operation can carry out glibly.

According to another aspect of the present invention, provide one to have the cabinet that prevents the while withdrawing device, it has multi-layer drawers, and comprises: be arranged on the drawer side guiding parts on each drawer, this drawer side guiding parts comprises the block with rod unit or tipper; The pillar that moves up and down with respect to this physical efficiency of cabinet; Pillar side guiding parts, this pillar side guiding parts comprises block or the rod unit with tipper, be arranged on the pillar and corresponding to each drawer side guiding parts, when extracting drawer out, cooperate with each drawer side guiding parts, can move to stop position to pillar from common position, this stop position refers to the position that the drawer of taking in is maintained reception position, but when pushing back the drawer that has been drawn out of, by cooperating with the drawer side guide piece, pillar can return initial common position; Maintaining body remains on this position to the pillar that moves to stop position, and keeps open in that pillar is returned under the effect of certain force of initial common position; Vertically be provided with but the thread-like member of energy transverse curvature; Limiting mechanism makes this thread-like member fix its end under the state of certain slack having, or connect a spring on its at least one end, can reduce the slack of thread-like member when usual, also can make this spring be elongated to set amount simultaneously; The yielding parts that do not have the axle supporting, the extension component that has head and extend from this head when extracting drawer out when the pillar side guiding parts cooperation corresponding with it of drawer side guiding parts, cooperates with arbitrary guiding parts, makes a concession mobile.For making a concession parts, in the middle of making a concession, thread-like member produces the stop deflection at least, under deflected,, make a concession with the yielding parts of fixing another drawer of thread-like member corresponding to another drawer, but when further extracting another drawer out, thread-like member can not guarantee enough slacks.

With the structure difference of first aspect present invention be, substitute connector (and augmentor), used yielding parts and thread-like member (spring assembly and restraint device).When extracting a drawer out, corresponding yielding parts are made a concession, thread-like member is lax, this is made a concession parts and can do to make a concession mobile, but under back-off state, when wanting to extract out other drawers, because the loose quantity not sufficient of thread-like member, the yielding parts of that drawer that correspondence wants to extract out can not reach the yielding of necessary amount and move.Therefore (roughly simultaneously) extracts two drawers out simultaneously.Can only be disposed at this thread-like member between certain two adjacent drawer, also can be located between whole drawers.Promptly to the orlop drawer, be provided with from the superiors.Under the previous case, for example be applicable to the superiors and from last several second layer drawers, cabinet is toppled over dangerous maximum two-layer drawer and almost can not be extracted out simultaneously, has effectively prevented cabinet because neglectful tumbling.If all drawer all disposes, any two drawers almost can not be extracted out simultaneously, more effectively prevent cabinet because the careless overthrow accident that produces.

This makes a concession parts does not have bolster, so do not want bearing block, assembling is easy, and cost is also low.

Have in the cabinet that prevents the while withdrawing device above-mentioned, can only the above-mentioned withdrawing device simultaneously that prevents be set at cabinet left and right sides either side.

Because only prevent withdrawing device simultaneously in a side setting, amount of parts is few, can accelerate assembling speed, and reduce cost.

The specific embodiment

Fig. 1 is the stereogram as four layers of cabinet of cabinet one example of the present invention.On the cabinet body 10 that housing constitutes, multilayer each drawer 12A stem for stem from top to down, 12B, 12C, 12D.Between the side of cabinet body side inboard and drawer, the left and right sides be equipped with long pillar 14,14 ', they relatively the cabinet body move up and down, and extend through the superiors' drawer sidepiece and reach the sidepiece of orlop drawer.The mechanism of the following stated only one-sided have pillar also can, but in the present embodiment, be to keep left and right sides balance, and action is level and smooth when extracting drawer out, and therefore pillar all is housed in the left and right sides.But, only can reduce cost at side peace pillar.Below only describe with regard near the mechanisms the pillar 14 shown in Fig. 1 left side.The right side is the same.

In the following description, all be equipped with to the outstanding rod unit (being equivalent to drawer side guiding parts) of side direction in the side of each drawer, order is from top to bottom: 16A, 16B, 16C, 16D.In addition, on the height of each rod unit correspondence, order is equipped with guide pad (the being equivalent to pillar side guiding parts) 14A that is with tipper, 14B, 14C, 14D on pillar 14 from top to bottom.

Near the bottom of having omitted pillar 14 on Fig. 2, and illustrate the assembly on the top of decomposition.Pillar 14 is to become " " font parts with the sheet metal clod wash, on the position that each band tipper guide pad is installed, has cut opening 14HA, 14HB, 14HC, 14HD.Because the guide pad shape of each band tipper is identical, only introduces from the guide pad 14B of last several second drawer 12B correspondence.Under confined state, guide pad 14B has a tipper 14BK who tilts to descend to the front lower place in the drawer, and the hole 14BH that opens on the above-below direction is arranged on the assigned position of top, and the hole 14BH ' of above-below direction is arranged on the assigned position of bottom.

In addition, that side at the guide pad that faces toward pillar 14 has prominent cooperation foot L1 to pillar, L2.Embrace " " font pillar two edges 14F1 with this a pair of " foot ", 14F2 is fixed.Be equipped with a sufficient LK of guiding between this two foot, it is to move up and down guiding for following yielding parts 14BT and limiting part 14BR.This guide pad is the single piece that is formed from a resin.

Above-mentioned yielding parts 14BT has an insertion section and a cam part BH, and described insertion section has the hole 14BTH that inserts following pitman AB lower end, and the right side position of described cam part BH on Fig. 2 contacts cooperation with rod unit 16B.Limiting part 14BR has a BH ' of restriction portion, also has an insertion section, and this insertion section has the hole of accepting pitman BC upper end.The described restriction BH ' of portion has an inclined plane 14BRK who almost becomes a face with the lower wall almost parallel of top guide pad tipper, when the assembling guide pad with lower wall surface in Fig. 2 right side.

Above-mentioned foot L2 and leading between the sufficient LK, referring to Fig. 2, when parts 14BT was made a concession in the assembling of guide pad offside, the leading section of cam part BH stretches out from hole 14BH to be assembled; Lower position is among the BH ' of the restriction portion load hole 14BH ' with limiting part 14BR.Each insertion section of the offside of yielding parts and limiting part can move up and down respectively under the sufficient LK guiding of guiding by cooperating with the sufficient LK of guiding.

As mentioned above, the guide pad 14B that is assembled into by yielding parts and limiting part is inserted into the hole 14HB of pillar and the accepting area that this guiding foot is gone up each parts that keeps with the sufficient LK of guiding.Each accepting area is positioned between the portion of " " word shape pillar two edges.By above-mentioned two sufficient L1, the maintenance effect of L2 and insertion are configured to this hole 14HB, so guide pad 14B keeps moving up and down with pillar.Guide pad 14C corresponding to drawer 12C also is the same, do not need to make a concession parts on the guide pad 14A of the superiors' drawer correspondence, only assemble limiting part 14AR, corresponding to the guide pad 14D of orlop drawer, owing to do not need limiting part, only parts 14DT (there be not expression on the figure) is made a concession in assembling.

Like this, between the edge part of pillar, between the yielding parts 14BT on the assembled guide pad 14B in limiting part 14AR that pitman AB is connected to be assembled into guide pad 14A and bottom.Equally, at limiting part 14BR be assembled into below it between the yielding parts 14CT on guide pad 14C and connect with pitman BC, the limiting part 14CR of guide pad 14C (expression on Fig. 2) and being assembled into below it between the yielding parts 14DT (expression on the figure) between guide pad 14D connects with pitman CD.

For each attaching parts, limiting part that is positioned on the upper end and the yielding parts that are positioned on the bottom are called connector.Each parts of connector move on above-below direction together.Mobile together being meant fully simultaneously of what is called moved, or roughly moves simultaneously.Promptly with respect to pitman, limiting part and yielding parts etc., during if be adhesively fixed, this moving can be described as the complete while, do not adopt when being adhesively fixed if insert cooperation, the end of pitman has under the situation in certain wander up and down gap in each hole, produces certain hysteresis, is almost to carry out simultaneously.

On the edge of pillar 14 upper ends, have fixing hole 14K, the auxiliary section TBK of the sidepiece of holding member TB is press fit on the pillar.Have hole TH on the sidepiece of holding member TB, in this hole, insert helical spring CS and action component KB.A cam surface KS is housed on the assigned position of action component KB, and under assembled state, helical spring makes progress to the action component reinforcing at the left of Fig. 2.On the assigned position of the face portion of holding member TB, have " L " shape hole LH.

The action of said structure below is described when pulling out drawer.Fig. 3 is to be example with the action of pulling out drawer 12C, and the action diagram of connector is described.(a) figure is that each drawer is pushing back under the state, the state side view of guide pad 14B and 14C part.Pull out drawer 12C, the rod unit 16C that then protrudes in sidepiece moves to the left side of Fig. 3.The district is the position that each guide pad is positioned at tipper shown in the oblique line on Fig. 3, the matching part when described each rod unit passes through each tipper.At Fig. 4, also be the same among Fig. 5.

Under the state of Fig. 3 (a), the limiting part that each guide pad is in lower position interconnects with the yielding parts that are in upper side position, is positioned at the lower wall surface (obliquity that is in limiting part is also arranged) of tipper.Pull out drawer 12C more slightly from (a) state, just become (b) state.That is, the upper wall surface of the tipper 14CK that extruding is forwards tilted, corresponding to drawer extraction amount, 14C pushes to guide pad then.Because pillar 14 moves up and down the same amount so pillar 14 also rises jointly with guide pad 14C.

On the other hand, rod unit 16C contact be engaged in make a concession parts 14CT below.Therefore making a concession parts 14CT is also raised same amount upward.The limiting part 14BR of the guide pad 14B that pitman BC upward assembles also raises and measures equally, and the yielding parts 14BT that is assembled on the same guide pad 14B also is raised same amount.Pitman AB also is pushed up like this, and the limiting part 14AR of guide pad 14A also is pushed up same amount.

(c) figure expression drawer is drawn out of more state, behind the guide pad 14C, pillar 14 further rises, each parts of making a concession parts 14CT and the connector on it also rise, and tipper 14CK is and is bordering on complete open state, simultaneously, guide pad 14B on guide pad 14C, the limiting part 14BR of 14A, 14AR are each corresponding guide pad 14B, the state of each tipper of 14A of filling up.Under (c) state, when further extracting drawer 12C out, guide pad 14C is pressed against uppermost position, and drawer is completely pulled out of.

Following maintaining body is that pillar is maintained at uppermost position shown in Fig. 6 (c).This top position is a stop position.After drawer was drawn out of, each connector descended under the gravity effect, turns back to original position with respect to guide pad.For making this returning have higher reliability, each parts of each connector all link to each other with an end of afterburning parts such as helical spring, and the other end is connected with pillar and each guide pad, and afterburning downwards structure is just arranged under the normal condition.

As mentioned above, as pull out a drawer 12C, because pillar is maintained at stop position, if want to extract out other any one drawers, because each guide pad that is connected with pillar has also risen, rod unit can not enter the tipper of each guide pad.So other drawer can not pull.Represented that rod unit can not enter the state of tipper on the figure (c).

Otherwise, when drawer 12C is rolled back, the lower wall surface of rod unit 16C extruding tipper 14CK, this power is unclamped the confining force of maintaining body, and pillar 14 descends, and drawer can be pushed back.

The relative action relationships of above-mentioned drawer and pillar belongs to technical scope in the past, and the above-mentioned action of each connector of emphasis of the present invention mechanism does not produce any obstruction in the past action relationships, and can guarantee action in the past.That is, the present invention is on the basis of basic structure in the past, has appended a connector, because essential structure is based on experience in the past, is reliable, so the reliable in action height of cabinet of the present invention.

Secondly, the situation (comprising the almost situation of while) that explanation can not be extracted two drawers simultaneously out with reference to Fig. 4.The rod unit 16C of Fig. 4 (a) is identical with (b) state of Fig. 3 with the relation of making a concession parts 14CT.At this moment, extract drawer 12C out when, if want to extract out the drawer 12B that is in the top simultaneously, the yielding parts 14BT combination that its rod unit 16B can and come out in the tipper is advanced.

But, when drawer 12C is retracted to state shown in Fig. 4 (b), makes a concession parts 14CT and be forced into fully and make a concession the position, its as a result the limiting part 14BR of upside forced up, the tipper of upside guide pad 14B is stopped up fully.Therefore, the rod unit 16B of drawer 12B can not readvance.That is, rod unit 16B must not advance and retreat in the tipper of guide pad 14B, and pillar self also is locked in this position.As a result, guide pad 14C can not further rise, and then can not extract drawer 12C out.So just prevent to extract out simultaneously two drawers.

When extracting any two drawers out, the drawer of its below is considered by Fig. 4 below drawer, wants to extract out the top drawer and considers to get final product by the drawer of Fig. 4 top, can prevent that any two drawers from extracting out simultaneously.Certainly, can not extract drawer more than three or three simultaneously out.

In the above-described embodiment, be the structure that pillar is moved upward.But tipper is made the groove that forwards rises, can be along with the carrying out of extracting action out, the downward side shifting of pillar meeting, maintaining body keeps the structure of this state, owing to be identical connector, also can prevent to extract out simultaneously.Also can consider the upside of Fig. 2 as downside.In this case in order to make each connector turn back to the original position of top, at least want the afterburning gravity that overcomes connector, usual to being connected somewhere an of end of the afterburning parts such as helical spring of reinforcing and connector be connected the other end on pillar or the guide pad up.One is illustrated in Fig. 8.Remain on yielding parts 14CT on the upside guide pad 14C and downside guide pad 14B go up connector that the limiting part 14BR that keeps is connected with pitman BC be equipped with helical spring 24 ', 24 ", an end of spring is connected on the excellent BC, the other end is positioned on the pillar 14.Two helical springs draw the connector left and right symmetrically obliquely upward with same power.Other pitman CD, AB also are equipped with same helical spring.Pacifying same afterburning helical spring symmetrically and be to making the motion slyness of connector, even if good but only pacify a helical spring.Also have without helical spring, and use other afterburning methods good.Different with this example is only to be equipped with helical spring at (on the pitman AB) on the connector of lower side, and uneasy good on other connectors.This is because the helical spring of pacifying on the connector of lower side etc. can make three connectors all afterburning upward.

When pillar moves up, make a concession parts and make a concession downwards with respect to pillar.Thereunder also can connect limiting part.Also afterburning parts must be arranged in this case, in addition, with aforementioned the same, the structure of this form also can come last subinverse to consider.

Corresponding to the connector and the guide pad of each drawer, also needn't all make equally.But making same shape just can reduce cost like this with a die forming.They are made other shapes also is the same.

Maintaining body below is described.Fig. 7 is an interior view of seeing the upper left quarter of Fig. 1 cabinet from the positive direction of cabinet, behind the key insertion KY of key mechanism shown in Figure 1, and under the situation of rotation, the key rod KYK rotation of to about cabinet, extending.But on the position with respect to pivot axis C0 off-centre, the convex component 22 of a direction extension equally to the left and right is housed, rotates with the key rod.

Fig. 6 sees Fig. 7 from the right side, and on the assigned position of the face portion of holding member TB, the hole LH that " L " shape is housed cooperates with aforementioned convex component 22.(a) state is the state that pillar 14 is positioned at the common position of below, at this moment can extract each drawer out, just becomes (b) state if lock.Be that convex component 22 changes half cycle afterwards to the top position, at this moment, with holding member TB pillar 14 mentioned and be the maintenance state owing to cooperate with " L " shape hole LH.

And then, upwards pushing away pillar 14 from (a) state, convex component 22 extruding on one side is located at the cam surface KS of action component KB, by the vertical hole of " L " shape relatively downwards move on one side.Action component KB with cam surface, under the effect of helical spring CS, to the left reinforcing of Fig. 6, the action component that overcomes this additional force is pressed to right-hand, and relatively shifts to the below.Therefore, when cam surface was in lower position, action component will turn back to original position under the effect of helical spring additional force.When pillar 14 is in the position of the top, i.e. (c) state.The maintenance of this state is to lean on the reinforcing effect of helical spring CS to realize.Yet, overcoming additional force pillar is pulled to the below, action component KB slowly shifts to the right side and turns back to (a) state.

Fig. 5 illustrates that another prevents the structure of extracting out simultaneously, is the foregoing description that replaces with connector, and this structure is to have used a laterally thread-like member 20 of energy deflection.The also available rope of so-called thread-like member 20, chain.Figure (a) (b) (c) is explanation at the rod unit of drawer 12C correspondence and matching relationship between the guide pad 14C ' of tipper is arranged.Each figure above the figure is the top view of following figure.Thread-like member 20 is to be positioned between the two edges portion of pillar 14 of form shown in Figure 2 on the above-below direction.

Thread-like member only is contained between adjacent two drawers, or surpasses two drawer length.Thread-like member is from the position corresponding to last layer drawer in the present embodiment, vertically installs to the height and position of basecoat drawer correspondence, has certain slack, and both ends are fixed on the cabinet body 10 up and down, also can be fixing with respect to pillar 14.Under the situation, one has slack will cause operate miss at ordinary times, therefore wants at ordinary times the tensioning thread-like member.At least at one end set up additional powerful elasticity parts such as helical spring for the tensioning thread-like member, make thread-like member always be in tensioning state or reduce deflection when usual.

For the thread-like member that connects spring members, only give certain slack in case of necessity, therefore the limiting mechanism that restraining spring parts can only be stretched a long ormal weight δ is housed.The lower end of thread-like member 20 for example shown in Figure 9 is fixed on the cabinet body 10, and the upper end is connected with spring 24, and the upper end of spring members is fixed on the cabinet body 10.A dish 26 is housed near the junction of thread-like member and spring members, in addition, usually the position from dish is provided with a restriction portion 28 to the position below the afore mentioned rules amount δ length, and this restriction portion is located on the cabinet body, makes this dish slippage downwards can not surpass δ.Double dot dash line 20 ' picture be the relaxed state of thread-like member.Maximum in this example slack is δ, but also might make thread-like member 20 have relaxed state to take place under the A-stage that connects spring members.So the value of maximum slack should be that the initial stage slack adds δ again, replace also can using pillar with the Over-The-Counter body.

Other guide pad also is the same, but stop guide pad 14C ' forms an outstanding protuberance PT on the space at the 14F1 of two edges portion, the 14F2 of stop guide pad 14C ' on the pillar two edges 14F1 of portion, the 14F2, this protuberance is between pillar hole 14HC and cooperates foot L1, between the L2.The front end that is communicated with tipper 14CK until protuberance in the inside of this protuberance all is skewed protuberance, essentially rectangular section hole GM of inner formation, and this angling hole arrives the front end of protuberance, oblique departure direction facing to extracting direction (left of Fig. 5) out.

In this angling hole, the hole head has individual broad place that yielding parts 14CCT is installed.These yielding parts can move along the incline direction of hole GM, have the groove PTS of a up/down perforation on the head of raised part PT and yielding parts separately, 14CRS.Above-mentioned thread-like member 20 is up and down by these grooves.Groove PTS is communicated with the angling hole GM of protuberance PT inside.Thread-like member 20 is linearly by each groove in each groove, from making a concession the extension component that the parts head extends, is projected in the tipper 14CK.(a) state of Here it is Fig. 5.

As long as extract drawer 12C a little out, just become (b) state from (a) state.It is the initial state that parts are made a concession in the outstanding rod unit 16C contact of drawer sidepiece.The same with the foregoing description, pillar 14 is moved upward.Any the words of then pulling outward again just become (c) state.Be that rod unit 16C makes the yielding parts be in the state of more making a concession, the head of making a concession parts is extruded the end of angling hole GM, but because the edge 14F1 of pillar, and the miscellaneous part 15 etc. that fills up the configuration of pillar " " word shape space, can maintain and make a concession parts and do not fall down.If only do not fall down for keeping, also can be outwards open its protuberance of angling hole GM PT, near the protuberance end as terminal.Also can make protuberance to angling hole for the ease of assembling yielding parts outwards opens.

Can see clearly from (b), (c) figure, by the distance that the thread-like member 20 of groove is made a concession to the protuberance direction corresponding to the yielding parts, make a concession parts and be pulled to head, portion cooperates with " " word sigmoid size.Therefore under the effect of lax or the spring members and the limiting member of thread-like member, in the slack scope that allows, yielding is possible.Aforementioned a certain amount of lax, to make a concession under the parallel situation in parts top and bottom, the yielding distance range of making a concession parts when extracting a drawer out is less than 4 times greater than 2 times.

If drawer 12C is retracted to the position of (c) state, rethink under the situation of extracting any one drawer out, because the possible relaxed length of thread-like member 20 is more than 2 times of yielding amount, for example other drawer may be pumped to (b) state, but can not be extracted into (c) state.This is because 4 times cause of the discontented yielding amount of slack.Therefore (almost simultaneously) extracts two drawers out simultaneously, prevented that cabinet is owing to tumbling of causing because of carelessness.

Pillar 14 as shown in Figure 6, maintains by maintaining body on application position, extracts other drawer from the cabinet back so can not resemble in the past the structure.If thread-like member has certain amount of deflection, extract out down under the situation of drawer by (c) state, effect has the straight line return force as initial state (a).Therefore making a concession parts also can return original (a) position.Connect a spring members on the thread-like member 20 in order to ensure returning to be preferably in, with the above embodiment.

After drawer 12C was drawn out of, its rod unit 16C contacted with the yielding parts that turn back to original position under the situation that wants to roll back.Making a concession parts itself can tilt along above-mentioned angling hole GM direction, at the border 14CU of angling hole GM and tipper 14CK, between the 14CU offside 14CRU certain space is arranged near extension that extends out from yielding parts head and the aforementioned boundary portion.The back vertex angle part of making a concession the parts head is pruned, is made it in angling hole, with upper and lower to axle be the center, can rotate.Therefore after rod unit 16C is extruded, make a concession, make a concession along angling hole to regaining the direction rotation.Drawer is rolled back smoothly like this.

Last example is to be the example explanation with the 3rd layer drawer 12C.Owing to use which drawer can illustrate too, so above explanation has generality.Also have, change the incline direction of guide pad tipper, pillar can move downwards, is the same with the example that uses connector.

In the mechanism that Fig. 5 represents, with the protuberance PT of resin, get final product on the guide pad of band tipper with the integral molded plastic shaping with definite shape.Making a concession parts also can adopt injection moulding process to be shaped simply.Afterwards, only can realize installing making a concession parts insertion guide pad.Can save operations such as pivot, pin and shaft piece are installed.The guide pad that insertion is assembled install on the pillar (perhaps guide pad is installed on the pillar 14, and then insert make a concession parts also can), again thread-like member is passed groove at last.Like this, make, assemble simply, cost is very low.

Use the highlight bar parts to make drawer side guiding parts in the drawer side above, used the guide pad that groove is arranged as pillar side guiding parts in the pillar side, yet also they may have been changed form etc., produced various variation.The maintaining body of explanations such as Fig. 6 also can have various distortion.For example L shaped hole does not need, and has only the hole of extending up and down passable as the present invention yet.Even also can be locked by mechanism for locking up in the hole of Yan Shening up and down.

See that by above explanation is clear the present invention can provide a kind of cabinet that prevents to extract out simultaneously two drawers.
