Description

本発明は、抽斗を有する家具に関する。   The present invention relates to furniture having a drawer.

収納状態における抽斗をばねの力によって常時押し出す方向に付勢するタイプのワゴンやキャビネット等の家具がある。例えば下記特許文献１，２の中に例示されている。特にこうしたタイプの家具では、収納した抽斗が飛び出さないようにするために、引手操作によって解除可能なラッチ部材を筐体側に設けたラッチ掛具に係止させておく必要がある。また、ワゴンやキャビネットには施錠装置を設けることが普通である。施錠の機構としては、抽斗側面部に突出させた凸部に係止する係止部材を筐体側に設けることが一般的である。
特開２００２−１７４０６６号公報 特許第３８２７９４３号公報 There are furniture such as wagons and cabinets that urge the drawer in the stowed state in a direction that is always pushed out by the force of a spring. For example, it is illustrated in the following Patent Documents 1 and 2. In particular, in such a type of furniture, in order to prevent the housed drawer from popping out, it is necessary to lock a latch member that can be released by a pulling operation to a latch hook provided on the housing side. Moreover, it is normal to provide a locking device in a wagon or a cabinet. As a locking mechanism, it is general to provide a locking member on the housing side for locking to a convex portion protruding from the drawer side surface.
JP 2002-174066 A Japanese Patent No. 3827943

上記タイプのワゴンやキャビネットでは、施錠装置を使って施錠した場合でも引手自体を操作することはでき、操作した場合、ラッチ部材の係合が外れる。しかし、収納状態の抽斗側面部の凸部と係止部材との間には幾分かの隙間があることが一般的であり、前記のラッチ部材のラッチ掛具との係合が外れた場合、収納状態の抽斗はばね力によって前記の凸部と係止部材間の隙間分だけ押し出される。そうすると、引手操作を止めても、ラッチ部材がラッチ掛具に係合する元の状態に復帰できないことが生じ得る。この場合、開錠をすると、引手操作をしていないにも拘らず、いきなり抽斗が飛び出すという不具合を引き起こすことになる。更には、施錠機構には鍵棒を使用しているが、鍵棒は細長いため、施錠によって長手方向に交差する方向の力を受ける場合は曲がりが生じ易く、廉価かつ簡便にこれを防止することも必要となる。
そこで、本発明の目的は、上記タイプの抽斗を有する家具において、施錠されている状態で引手操作ができない構造の家具を提供することである。また、多段状の抽斗が精度良く上下方向に整列する構造の家具を提供する。 In the above-described type of wagon or cabinet, the handle itself can be operated even when locked using a locking device, and the latch member is disengaged when operated. However, it is general that there is some gap between the convex part of the drawer side surface part in the housed state and the locking member, and when the engagement of the latch member with the latch hook is released The stowed drawer is pushed out by the gap between the convex portion and the locking member by a spring force. Then, even if the pulling operation is stopped, the latch member may not be able to return to the original state where it is engaged with the latch hook. In this case, when unlocking is performed, the drawer suddenly pops out even though the pulling operation is not performed. Furthermore, although a key bar is used for the locking mechanism, since the key bar is elongated, bending is likely to occur when receiving a force in a direction crossing the longitudinal direction due to locking, and this can be prevented inexpensively and easily. Is also required.
Accordingly, an object of the present invention is to provide furniture having a structure in which a pulling operation cannot be performed in a locked state in furniture having a drawer of the above type. Further, the present invention provides furniture having a structure in which multistage drawers are aligned in the vertical direction with high accuracy.

第１の発明では、筐体に収納された抽斗が出し入れ自在な家具であって、収納状態の抽斗には、筐体との間に作用する第１の弾性部材の付勢力によって該抽斗を押し出す力が作用しており、抽斗の前面部に設けられ、指で押せば後方に移動し、指を離せば第２の弾性部材の付勢力によって元の状態に復帰するプッシュ式引手を有し、この引手の前後動に連動するラッチ部材が、筐体に固定されたラッチ掛具に係脱可能であり、筐体内の上下方向に施錠装置の一部をなす鍵棒が延設され、前記ラッチ部材に対応する高さ位置の鍵棒に係止部材が該鍵棒と一体回転可能に装着されており、該係止部材は施錠操作によって前記ラッチ掛具に係合しているラッチ部材に直接に係止すると共に、開錠操作によってラッチ部材との係止が解除され、施錠操作によって、前記係止部材を前記ラッチ部材との係止を開放させる方向に常時付勢している第３の弾性部材の付勢力に抗しつつ、前記鍵棒はその軸線回りに回転し、該係止部材を装着している高さ位置の鍵棒と筐体の内壁面との間に亘ると共に、前記ラッチ掛具と一体に形成された鍵棒受けを具備することを特徴とする家具を提供する。
この第１発明では、施錠装置の施錠ブロック部は筐体に設けられていても良く、また、抽斗に設けられていてもよい。また、抽斗は１段だけでもよい。 In the first invention, the drawer housed in the housing is freely removable, and the drawer in the housed state is pushed out by the biasing force of the first elastic member acting between the housing and the housing. Force is applied, provided on the front part of the drawer, has a push-type pull that moves backward when pressed with a finger, and returns to the original state by the biasing force of the second elastic member when released. The latch member interlocking with the forward / backward movement of the pulling handle is detachable from a latch hook fixed to the casing, and a key bar that forms a part of the locking device is extended in the vertical direction in the casing. the locking member in the key bar height position corresponding to the member is mounted integrally rotatably with said key rod, locking member directly to the latch member engaged with the latch Kakegu by locking operation with locking, the engagement between the latch member by unlocking operation is released, locking Misao Accordingly, while resisting the urging force of the third elastic member that constantly urges the locking member in a direction to open the locking of the latch member, said key bar is rotated around its axis, said A furniture characterized by comprising a key bar receiver integrally formed with the latch hook and extending between the key bar at a height position where the locking member is mounted and the inner wall surface of the housing. provide.
In this 1st invention, the locking block part of a locking device may be provided in the housing | casing, and may be provided in the drawer. Also, the drawer may be only one stage.

第２の発明では、第１の発明の抽斗が多段状に配設された家具であって、前記施錠装置の施錠ブロック部が特定の抽斗の前面部に設けられており、施錠操作によって第３の弾性部材の付勢力に抗しつつ左右方向の何れか一方向に移動して前記鍵棒を回転させ、前記ラッチ掛具に係合しているラッチ部材に係止部材を係止させるよう作動する左右移動材を有し、各抽斗の前面部の左側面又は右側面に対面する筐体の左右内面側であって、前記一方向の側の筐体内面側には、抽斗前面部の側面を付勢する弾力性サイド部品を設けているよう構成する。   In the second invention, the drawer of the first invention is a multi-stage furniture, and the locking block portion of the locking device is provided on the front surface of the specific drawer, and the third operation is performed by the locking operation. Actuate to lock the locking member to the latch member engaged with the latch hook by rotating in one of the left and right directions while rotating against the urging force of the elastic member. Left and right inner surfaces of the housing facing the left side or the right side of the front portion of each drawer, and the side of the front portion of the drawer on the inner surface side of the one direction side It is constituted so as to provide elastic side parts for energizing.

第３の発明では、第２の発明の筐体の左右内面の内の前記弾力性サイド部品を設ける側とは反対側には、夫々、前記弾力性サイド部品をその弾力性に抗して完全に押し付けた際の厚さと同じ厚さＴを有する定厚サイド部品を設けており、各抽斗前面部の左右側面と、該左右側面の対面する筐体左右内面との左右の各隙間を同じ値に振り分けた場合のその隙間寸法をΔとすれば、０．８５・Δ≦Ｔ＜Δの関係になるように、両種類のサイド部品は前記隙間寸法Δに近い厚さＴを有するよう構成する。好ましくは、０．９・Δ≦Ｔ＜Δである。   In the third aspect of the present invention, the elastic side component is completely opposed to the elastic side component on the side opposite to the side on which the elastic side component is provided in the left and right inner surfaces of the housing of the second aspect. Constant thickness side parts having the same thickness T as the thickness when pressed against the left and right sides of the left and right side surfaces of the front of each drawer and the left and right inner surfaces of the housing facing each other are the same value If the gap dimension when the two parts are distributed is Δ, both types of side parts are configured to have a thickness T close to the gap dimension Δ so that 0.85 · Δ ≦ T <Δ. . Preferably, 0.9 · Δ ≦ T <Δ.

第１の発明では、係止部材が施錠操作によってラッチ掛具に係合しているラッチ部材に係止するため、施錠後は、引手を操作しようとしてもラッチ部材の係合を解除できず、既述のような不具合を防止できる。また、鍵棒のラッチ部材に対応する高さ位置に係止部材が一体回転可能に装着されているため、施錠をすると、この係止部材を介して鍵棒には横方向の力（曲げ力）が作用し得るが、この鍵棒には係止部材を装着している高さ位置の部位と筐体内壁面との間に亘る鍵棒受けを設けているため、鍵棒の曲げが生じ難く、信頼性高く施錠できる。更には、この鍵棒受けはラッチ掛具と一体に形成されているため、鍵棒の支持補強に対する効果が大きくなる他、部品点数が減少する。   In the first invention, since the locking member is locked to the latch member engaged with the latch hook by the locking operation, after locking, the engagement of the latch member cannot be released even if the handle is operated, Problems such as those described above can be prevented. In addition, since the locking member is mounted at a height position corresponding to the latch member of the key bar so as to be integrally rotatable, when locked, a lateral force (bending force) is applied to the key bar via the locking member. However, since the key bar is provided with a key bar holder that extends between the height position where the locking member is mounted and the inner wall surface of the housing, the key bar is unlikely to be bent. Can be locked with high reliability. Furthermore, since the key bar receiver is formed integrally with the latch hook, the effect of reinforcing the key bar is increased and the number of parts is reduced.

第２の発明では、施錠装置の施錠ブロック部が特定の抽斗の前面部に設けられており、施錠操作によって左右移動材を第３の弾性部材の付勢力に抗しつつ左右の何れか一方向に移動させてラッチ掛具に係合しているラッチ部材に係止部材を係止させるため、この特定抽斗は前記一方向とは逆方向に付勢される。このため、付勢力を受けない他の抽斗とは抽斗前面部の側面ラインが揃わない。これを防止するため、該他の抽斗の前面部に対面する筐体の内面側であって、前記一方向の側の筐体内面側に弾力性サイド部品を設ける。更には、開錠状態では、前記特定抽斗は第３の弾性部材の付勢力を受けることはなく、しかも、該特定抽斗の前記一方向の側の筐体内面側に弾力性サイド部品を装着していなければ、該特定抽斗が該一方向の側に偏ることがある。これを防止するため、この特定抽斗の前面部側面に対面する前記一方向の側の筐体内面側にも他の抽斗に対応するものと同じ弾力性サイド部品を装着させる。   In the second invention, the locking block portion of the locking device is provided on the front surface portion of the specific drawer, and the left and right moving material is resisted against the urging force of the third elastic member by the locking operation in either the left or right direction. In order to lock the locking member to the latch member engaged with the latch hook, the specific drawer is biased in the direction opposite to the one direction. For this reason, the side line of the front part of the drawer does not align with other drawers that do not receive the urging force. In order to prevent this, an elastic side part is provided on the inner surface side of the casing facing the front surface of the other drawer, and on the inner surface side of the casing in the one direction. Furthermore, in the unlocked state, the specific drawer does not receive the urging force of the third elastic member, and a flexible side part is attached to the inner surface of the casing on the one direction side of the specific drawer. If not, the specific drawer may be biased toward the one direction. In order to prevent this, the same elastic side parts as those corresponding to the other drawers are mounted on the inner surface of the casing in the one direction facing the side surface of the front surface of the specific drawer.

第３の発明では、第２の発明のように抽斗前面部の側面ラインが揃うのみならず、各抽斗左右と筐体框部との間の隙間を可及的に同じに設定することが可能となる。即ち、所定の押圧条件の弾力性サイド部品も定厚サイド部品も同じ厚さであり、この厚さＴを各抽斗左右と筐体框部との間の設定隙間Δの９０％程度（８５％以上１００％未満）に設定することにより、左右の実隙間の差を小さくできる（殆ど同じ値にすることができる）。   In the third invention, not only the side lines of the front surface of the drawer are aligned as in the second invention, but also the gap between the left and right of each drawer and the casing collar can be set as much as possible. It becomes. That is, the elastic side part and the constant-thickness side part under a predetermined pressing condition have the same thickness, and this thickness T is about 90% (85%) of the set gap Δ between the left and right of each drawer and the casing collar. By setting it to less than 100%, the difference between the left and right actual gaps can be reduced (can be set to almost the same value).

図１は本発明に係る家具の例としてのワゴン型の３段キャビネットの正面図である。各抽斗２０，４０，６０は、その収納状態において常時前方に押し出す付勢力が作用する構造となっている。その具体例として、図２には最上段の抽斗２０の後部に装着した付勢機構を模式的に図示しているが、他の抽斗も同様である。抽斗後部側面の外側或いは内側に固定したケース７０に対して進退棒７２を前後方向に貫通させている。この進退棒に固定された鍔部７３とケース端面との間にコイルスプリング７６が配設されている。進退棒７２の後端部にはゴム製端部部材７４が設けられており、抽斗２０を収納した際に、部材７４が筐体１０の後部内面等に当接、押圧することで、進退棒７２が矢印方向（前方向）に移動し、コイルスプリング７６が圧縮される。この付勢力によって抽斗２０を押し出す力が作用する。他の抽斗も同様である。   FIG. 1 is a front view of a wagon type three-stage cabinet as an example of furniture according to the present invention. Each of the drawers 20, 40, 60 has a structure in which a biasing force that always pushes forward in the stored state acts. As a specific example, FIG. 2 schematically shows an urging mechanism attached to the rear portion of the uppermost drawer 20, but the same applies to other drawers. An advancing / retreating rod 72 is penetrated in the front-rear direction with respect to the case 70 fixed to the outer side or the inner side of the rear side of the drawer. A coil spring 76 is disposed between the flange 73 fixed to the advance / retreat rod and the case end surface. A rubber end member 74 is provided at the rear end portion of the advance / retreat rod 72, and when the drawer 20 is stored, the member 74 abuts against and presses the inner surface of the rear portion of the housing 10, so that the advance / retreat rod is provided. 72 moves in the direction of the arrow (forward direction), and the coil spring 76 is compressed. A force for pushing out the drawer 20 is applied by this biasing force. The same applies to the other drawers.

図４は引手によるラッチ部品の係脱機構（ラッチ機構）の斜視図であり、図６は図１の矢視線Ｆ−Ｆによる拡大断面図であり、一部簡略化している。各抽斗には図４や図６に示すラッチ部品３４をラッチ掛具３６に係脱させるための引手２４が設けられており、この実施例ではプッシュ式の引手を採用している。抽斗２０の前部の縦断面図を図３に示す。前面部２２の前面板には適宜な位置に開口２２Ｋを設けており、この開口に嵌っている引手２４を指で押す。そうすると、図３に示すように引手２４は蝶番の軸２６を枢軸として後方から支持しているコイルスプリング等のばね部材３１の付勢力に抗しつつ回動して後方に傾斜する。ばね部材３１と引手の間には介在部材２８が介在している。この介在部材の下方部に、該介在部材が固定装着されている水平軸３０が水平状態で、その中心軸線３０Ｊ回りに回転可能に軸受されている。従って引手２４を押すことによって水平軸３０が矢印方向に回転し、該水平軸の端部が概ね下方に向かってＬ字状に折れ曲がった軸端部３０Ｅが、前記中心軸線３０Ｊを中心として矢印の方向に回動する。   4 is a perspective view of a latch part engaging / disengaging mechanism (latch mechanism) by a pull handle, and FIG. 6 is an enlarged cross-sectional view taken along line FF in FIG. 1 and is partially simplified. Each drawer is provided with a handle 24 for engaging and disengaging the latch component 34 shown in FIGS. 4 and 6 with the latch hook 36. In this embodiment, a push-type handle is employed. A longitudinal sectional view of the front portion of the drawer 20 is shown in FIG. An opening 22K is provided at an appropriate position on the front plate of the front portion 22, and a puller 24 fitted in the opening is pushed with a finger. Then, as shown in FIG. 3, the handle 24 rotates and tilts backward against the urging force of a spring member 31 such as a coil spring that supports the hinge shaft 26 from the rear as a pivot. An interposition member 28 is interposed between the spring member 31 and the handle. A horizontal shaft 30 to which the interposition member is fixedly mounted is rotatably supported around the central axis 30J in a horizontal state below the interposition member. Accordingly, by pushing the puller 24, the horizontal shaft 30 rotates in the direction of the arrow, and the end 30E of the horizontal shaft that is bent in an L-shape substantially downward is centered on the central axis 30J. Rotate in the direction.

図４を参照すると、前記水平軸３０とラッチ部品３４との間には、その中心軸線３２Ｊを中心として回転可能に軸受された上下方向軸３２が介在しており、その上端部はラッチ部品３４に固定されている。この上下方向軸の下端部は水平方向にＬ字状に折れ曲がった軸端部３２Ｅに形成されている。従って、前記軸端部３０Ｅの中心軸線３０Ｊを中心とした回動によって、この軸端部３２Ｅが中心軸線３２Ｊを中心として、矢印の方向に回動する。その結果、ラッチ部品３４は矢印の方向に回動し、ラッチ掛具３６との係合が外れる。また、上下方向軸かラッチ部品には、図示を省略しているばね部材によって、常時、ラッチ掛具に係合する方向（図４のラッチ部品の矢印とは逆の方向）の付勢力が作用している。   Referring to FIG. 4, a vertical shaft 32 that is rotatably supported around the central axis 32 </ b> J is interposed between the horizontal shaft 30 and the latch component 34. It is fixed to. A lower end portion of the vertical axis is formed at a shaft end portion 32E that is bent in an L shape in the horizontal direction. Accordingly, the rotation of the shaft end portion 30E around the central axis 30J causes the shaft end portion 32E to rotate about the center axis 32J in the direction of the arrow. As a result, the latch component 34 rotates in the direction of the arrow, and the engagement with the latch hook 36 is released. In addition, an urging force in a direction that is always engaged with the latch hook (the direction opposite to the arrow of the latch part in FIG. 4) acts on the vertical axis or the latch part by a spring member (not shown). is doing.

図５は施錠装置の施錠ブロック部１２近くの拡大正面図であり、施錠ブロック部１２はこの例では最上段の抽斗２０に設けられているが、他の抽斗４０，６０に設けられていてもよい。施錠ブロック部１２の後部には、鍵の施錠又は開錠操作によって施錠ブロックの中心回りに回動するピン軸部１４が設けられている。また、このピン軸部が係合する凹部１６Ｋを有する左右移動材としての左右移動板部材１６が左右方向にのみ移動可能に配設されている。図５に示す矢印は施錠操作時の方向であり、鍵を施錠操作すると前記ピン軸部１４が左右移動板部材１６を右方向に押しつつ矢印方向（時計回り方向）に回動移動する。その移動結果位置を１４’で示している。即ち、左右移動板部材はその分だけ右に移動する。   FIG. 5 is an enlarged front view near the locking block portion 12 of the locking device. The locking block portion 12 is provided in the uppermost drawer 20 in this example, but may be provided in other drawers 40 and 60. Good. A pin shaft portion 14 that rotates around the center of the locking block by a key locking or unlocking operation is provided at the rear portion of the locking block portion 12. Further, a left / right moving plate member 16 as a left / right moving member having a recess 16K with which the pin shaft portion engages is disposed so as to be movable only in the left / right direction. The arrow shown in FIG. 5 is the direction at the time of the locking operation, and when the key is locked, the pin shaft portion 14 rotates in the direction of the arrow (clockwise direction) while pushing the left and right moving plate member 16 to the right. The movement result position is indicated by 14 '. That is, the left / right moving plate member moves to the right by that amount.

図６を参照すると、筐体１０の内側であって、抽斗側板との間の空間に、中心軸線４０Ｊを中心として回転可能であって、上下方向に延伸した鍵棒４０が配設されている。この鍵棒と共に回転するようレバー４２が設けられており、開錠状態における左右移動板部材１６の端部（図６の右側）近くにレバー端部が位置している。また、係止部材として、図６に示す形状のＬ字形の鍵板４４が鍵棒と共に回動するように鍵棒に対して固定されている。   Referring to FIG. 6, a key bar 40 that is rotatable about a central axis 40 </ b> J and extends in the vertical direction is disposed inside the housing 10 and between the drawer side plates. . A lever 42 is provided so as to rotate together with the key bar, and the end of the lever is located near the end (right side in FIG. 6) of the left and right movable plate member 16 in the unlocked state. Further, as a locking member, an L-shaped key plate 44 having the shape shown in FIG. 6 is fixed to the key bar so as to rotate together with the key bar.

施錠操作によって前記左右移動板部材１６が図６の右方向に駆動させる場合、コイルスプリング１８の付勢力に抗してレバー４２の端部を右方向に移動させる。即ち、レバー４２は中心軸線４０Ｊの回りに回動する。従って、鍵棒４０が回転し、これと共に鍵板４４が回動する。施錠を行うと、鍵板４４は２点鎖線４４’で示す位置に来る。この位置の鍵板は、ラッチ掛具３６に係合しているラッチ部品３４の図６における左側を押さえる状態に係止する。これによって、施錠状態の場合、引手２４を押そうとしても、ラッチ部品３４がラッチ掛具３６から外れない。従って、仮に鍵板の係止がこのラッチ部品に対してではなく、抽斗側部の凸部に係止する構造の場合、この凸部と鍵板とに存在し得る隙間分、図２に示す付勢機構の作用によって抽斗が前方に押し出され、これによって、ラッチ部品がラッチ掛具との係合状態に復帰できない事態が生じ得るが、本願構造ではこれを防止できる。   When the left / right moving plate member 16 is driven rightward in FIG. 6 by a locking operation, the end of the lever 42 is moved rightward against the urging force of the coil spring 18. That is, the lever 42 rotates around the central axis 40J. Therefore, the key bar 40 rotates and the key plate 44 rotates together with the key bar 40. When locking is performed, the key plate 44 comes to a position indicated by a two-dot chain line 44 '. The key plate at this position is locked in a state where the left side in FIG. 6 of the latch part 34 engaged with the latch hook 36 is pressed. Thereby, in the locked state, the latch component 34 does not come off from the latch hook 36 even if the handle 24 is pushed. Therefore, in the case of a structure in which the lock of the key plate is not locked to the latch part but to the convex portion of the drawer side portion, the gap that may exist between the convex portion and the key plate is shown in FIG. Although the drawer is pushed forward by the action of the urging mechanism, there may occur a situation in which the latch component cannot return to the engagement state with the latch hook, but this structure can prevent this.

開錠操作をすれば、左右移動板部材１６が左方向に移動するため、ばね１８の付勢力の作用によって鍵板４４は図６の実線で示す開放位置に復帰する。また、鍵棒４０は２段目の抽斗４０と３段目の抽斗６０の側面部にまで至っており、夫々の抽斗に設けたラッチ部品３４の高さ部分の鍵棒に同様の鍵板４４が固定されている。   If the unlocking operation is performed, the left and right moving plate member 16 moves to the left, so that the key plate 44 returns to the open position indicated by the solid line in FIG. The key bar 40 extends to the side surfaces of the second-stage drawer 40 and the third-stage drawer 60, and the same key plate 44 is provided on the key bar at the height of the latch part 34 provided in each drawer. It is fixed.

施錠時の左右移動板部材による力や、鍵板４４がラッチ部品３４に係止した場合に受ける力、或いは、この係止状態（施錠状態）において（誤って）引手２４を操作しようとする力等の力に起因する曲げ作用をする力を鍵棒４０は受ける。従って、この鍵棒の曲がり（撓み）を防止するため、鍵棒受け３７を、夫々の抽斗に対応する各鍵板の固定位置（ラッチ部品の高さ位置）の鍵棒を取り囲むように夫々配設している。この鍵棒受け３７は樹脂の射出成形品としてラッチ掛具３６と一体に形成している。この一体部品３８の平面視概略形状は、ラッチ掛具３６の部分が略三角形状であり、鍵棒受け３７の部分が略矩形状である。装着手法は、筐体１０の前部構造と関係があるため、まず筐体前部構造を説明する。   The force by the left and right moving plate member at the time of locking, the force received when the key plate 44 is locked to the latch component 34, or the force to operate the handle 24 (incorrectly) in this locked state (locked state) The key bar 40 receives a force that causes a bending action due to a force such as the above. Therefore, in order to prevent the bending (deflection) of the key bar, the key bar receivers 37 are respectively arranged so as to surround the key bars at the fixing positions (the height positions of the latch parts) of the respective key plates corresponding to the respective drawers. Has been established. The key bar receiver 37 is integrally formed with the latch hook 36 as a resin injection molded product. In the plan view schematic shape of the integrated part 38, the latch hook 36 has a substantially triangular shape, and the key bar receiver 37 has a substantially rectangular shape. Since the mounting method is related to the front structure of the housing 10, the housing front structure will be described first.

この例での筐体１０の前部構造は、図６に平面視を図示しているように、筐体の側板を前端部で内方に向かって折り曲げた第１折曲部１０Ａを有し、この第１折曲部を左右方向内側に向かって（図６では左方向に）折り曲げて第２折曲部１０Ｂを有し、この第２折曲部を後方に向かって筐体側板と平行になるよう折り曲げた第３折曲部１０Ｃを有し、更に、この第３折曲部を筐体の側板外方向に向けて折り曲げた、幅（折り曲げ方向長さ）の狭い第４折曲部１０Ｄを有している。この筐体側板には、少なくとも前部では、別部品である補強用フレーム部材等を溶接等で一体化させてはいない。そのため、前記一体部品３８を筐体１０に保持固定させるには前記の各折曲部を利用している。   The front structure of the housing 10 in this example has a first bent portion 10A in which the side plate of the housing is bent inward at the front end as shown in a plan view in FIG. The first bent portion is bent inward in the left-right direction (leftward in FIG. 6) to have a second bent portion 10B, and the second bent portion is parallel to the housing side plate toward the rear. A fourth bent portion with a narrow width (length in the bending direction), which is further bent to the outside of the side plate of the housing. 10D. This casing side plate is not integrated with a reinforcing frame member or the like which is a separate part by welding or the like at least in the front part. Therefore, in order to hold and fix the integrated part 38 to the housing 10, the bent portions are used.

前記第３折曲部１０Ｃには適宜な位置と大きさの貫通孔を形成しており、ここに、ラッチ掛具３６における、筐体側板に向かう面に設けた係合凸部３６Ｋを挿入係止させる。一方、第４折曲部１０Ｄの端面と筐体側板との間隙に鍵棒受け３７の前側部を挿入して間隙を埋め、鍵棒受け３７の筐体側板側の面が筐体側板内面に当接している。これにより、一体部品３８が筐体１０に対して固定されると共に、鍵棒４０の撓みが防止される。従って、鍵板４４によるラッチ部品への係止が信頼性高く可能となる。また、ラッチ掛具３６と鍵棒受け３７とを一体にしたため、部品点数が減少し、コスト低減に寄与する。   A through hole having an appropriate position and size is formed in the third bent portion 10C, and an engagement convex portion 36K provided on the surface of the latch hook 36 facing the housing side plate is inserted therein. Stop. On the other hand, the front side portion of the key rod holder 37 is inserted into the gap between the end surface of the fourth bent portion 10D and the housing side plate to fill the gap, and the surface on the housing side plate side of the key rod receptacle 37 is the inner surface of the housing side plate. It is in contact. As a result, the integral part 38 is fixed to the housing 10 and the bending of the key bar 40 is prevented. Therefore, the lock to the latch component by the key plate 44 can be performed with high reliability. Further, since the latch hook 36 and the key bar receiver 37 are integrated, the number of parts is reduced, which contributes to cost reduction.

上記図６の説明から判るが、筐体１０の框の幅は筐体の側板とその折り返し部である第１折曲部１０Ａとを併せた程度の厚さ寸法であり、この例では２．５ｍｍという細さである。従って、施錠装置の施錠ブロック部１２をこの框部に設けることは実質的に不可能である。このため、この例では最上段の抽斗２０に設けているが、第１の発明に関しては、施錠ブロック部は框部に設けていてもよい。また、この框と抽斗の前面部の左右側面（２２Ａ等）との成す隙間は、左右の各隙間を同じ値に振り分けた場合のその設定隙間をΔとすれば、Δ＝１．５ｍｍとしている。３個の抽斗の上下方向の整列状態、即ち、抽斗前面部の側面ラインができるだけ揃うようにしたい。また、左右の現実の隙間をできるだけ同じにしたい。このために、この実施形態例では、各抽斗に対応する右側框部の内側面には、図７に示す弾力性サイド部品５０を装着させ、左側框部の内側面には、図示しない定厚サイド部品を装着させる。   As can be seen from the description of FIG. 6 above, the width of the ridge of the housing 10 is a thickness dimension that combines the side plate of the housing and the first bent portion 10A that is the folded portion. It is as thin as 5 mm. Therefore, it is practically impossible to provide the locking block portion 12 of the locking device on the collar portion. For this reason, although provided in the uppermost drawer 20 in this example, the locking block portion may be provided in the collar portion with respect to the first invention. In addition, the gap formed by this basket and the left and right side surfaces (22A, etc.) of the front face of the drawer is set to Δ = 1.5 mm, where Δ is the set gap when the left and right gaps are distributed to the same value. . I would like the three drawers to be aligned in the vertical direction, that is, the side lines of the front face of the drawer are aligned as much as possible. Also, I want to make the gap between the left and right real as close as possible. Therefore, in this embodiment, the elastic side part 50 shown in FIG. 7 is attached to the inner side surface of the right side hook corresponding to each drawer, and the constant thickness (not shown) is attached to the inner side surface of the left side hook. Install the side parts.

上記したように、右側に弾力性サイド部品を設けるのは、この例では、施錠時に既述の左右移動板部材１６が右方向に駆動されるからである。即ち、コイルスプリング１８の付勢力に抗しつつ駆動されるため、抽斗２０はその反力としてこの左右移動板部材１６を介して左方向に押される。然しながら、他の抽斗４０，６０には施錠ブロック部１２と左右移動板部材１６は設けられていないため、こうした反力を受けることがない。このため、最上段の抽斗２０のみが左側に偏位することになり、抽斗前面部の側面ラインが揃わない。これを防止するために、２段目と３段目の各抽斗も左方向に付勢されるようにしたい。このため、２段目と３段目の各抽斗の前面部右側面に対面する筐体内面、即ち、框部の内側面（第１折曲部１０Ａの抽斗側の面）に弾力性サイド部品５０を装着させる。この弾力性サイド部品によって各抽斗は左方向に付勢されている。   As described above, the elastic side part is provided on the right side in this example because the aforementioned left and right moving plate member 16 is driven rightward during locking. That is, since it is driven against the urging force of the coil spring 18, the drawer 20 is pushed leftward as a reaction force through the left and right moving plate member 16. However, the other drawers 40 and 60 are not provided with the locking block portion 12 and the left and right moving plate member 16, and thus do not receive such reaction force. For this reason, only the uppermost drawer 20 is displaced to the left, and the side lines of the front face of the drawer are not aligned. In order to prevent this, it is desirable that the second and third stage drawers are also urged to the left. For this reason, elastic side parts are provided on the inner surface of the casing facing the right side surface of the front surface of each of the second and third stage drawers, that is, the inner side surface of the flange (the surface on the drawer side of the first bent portion 10A). 50 is put on. Each drawer is urged to the left by this elastic side part.

しかし、開錠状態では、抽斗２０にはコイルスプリング１８による左方向への付勢力は作用しない。このため、他の抽斗４０，６０にのみ左方向への付勢力を作用させる構造では、やはり、抽斗前面部の側面ラインが揃わない。そこで、施錠ブロック部を設けている抽斗２０に対しても他の抽斗４０，６０と同じ作用をする同じ弾力性サイド部品５０を、抽斗２０の前面部２２の右側面２２Ａに対面する筐体内面に設ける。   However, in the unlocked state, the leftward biasing force by the coil spring 18 does not act on the drawer 20. For this reason, in the structure in which the urging force in the left direction is applied only to the other drawers 40 and 60, the side lines of the front part of the drawer are not aligned. Therefore, the inner surface of the housing facing the right side surface 22 </ b> A of the front surface portion 22 of the drawer 20 with the same elastic side part 50 having the same action as that of the other drawers 40 and 60 also on the drawer 20 provided with the locking block portion. Provided.

これでいつも抽斗前面部の側面ラインが揃う。しかし、これだけでは、抽斗の左側の隙間と右側の隙間の各大きさは異なってしまい、右側隙間が大きくなる。そこで、定厚サイド部品を、弾力性サイド部品に対応する左側框部の内側面に装着させる。以下、これらのサイド部品につき、図７を参照しつつ説明する。また、これらの両種類のサイド部品は抽斗前面部の側面が当接しつつ擦ることを前提としており、抽斗の傷つき防止等の観点から樹脂製としている。   This always aligns the side lines on the front of the drawer. However, with this alone, the sizes of the left and right gaps of the drawer differ, and the right gap becomes larger. Therefore, the constant-thickness side part is attached to the inner side surface of the left side collar corresponding to the elastic side part. Hereinafter, these side parts will be described with reference to FIG. These two types of side parts are premised on rubbing while the side surfaces of the front face of the drawer are in contact with each other, and are made of resin from the viewpoint of preventing damage to the drawer.

図７（ａ）に示すように、平面視が矩形状を成しており、中央の立壁部５２の右側部５８は図６に示すように第２折曲部１０Ｂに設けたスリット状の貫通孔１０ＢＫを通して内部側に挿入させる部位である。その幅方向中央部であって、厚さ方向に弾力性のある爪部６０によって貫通孔１０ＢＫから前方への抜け止めを果たす。また、この爪部前端面と前記立壁部５２とによって第２折曲部１０Ｂを挟持すると共に、この右側部５８の後端縁部（図７の右端縁部）は筐体側面の内壁面に当接しており、これらが部品５０の装着固定の作用を成す。   As shown in FIG. 7A, the plan view has a rectangular shape, and the right side portion 58 of the central standing wall 52 is a slit-like penetration provided in the second bent portion 10B as shown in FIG. This is the part that is inserted inside through the hole 10BK. The claw part 60 which is the center part in the width direction and is elastic in the thickness direction prevents the through hole 10BK from coming off forward. The second bent portion 10B is sandwiched between the front end surface of the claw portion and the standing wall portion 52, and the rear end edge portion (the right end edge portion in FIG. 7) of the right side portion 58 is formed on the inner wall surface of the casing. They are in contact with each other and function to mount and fix the component 50.

部品５０の図７の左側部は、その幅方向中央部の厚さ方向に弾力性のある爪部 と、これを挟む位置に定厚部５４が形成されている。また、この定厚部も爪部も、その前側部分（図７の左側部分）５４Ｔ，５６Ｔは板厚が前端から後方に漸増する傾斜状に形成されている。定厚部５４の板厚Ｔはこの例では、１．４ｍｍであり、力の作用していない状態での爪部５６の上面までの高さＴＭは、この例では２ｍｍである。爪部５６を弾力性に抗して所定以上の力で押せば、この部品５０の図７の左側部としての厚さは定厚部板厚Ｔとなる。   On the left side of the component 50 in FIG. 7, a claw portion that is elastic in the thickness direction at the center in the width direction, and a constant thickness portion 54 are formed at a position sandwiching the claw portion. Further, both the constant thickness part and the claw part are formed in an inclined shape in which the front part (the left part in FIG. 7) 54T, 56T gradually increases from the front end to the rear. The plate thickness T of the constant thickness portion 54 is 1.4 mm in this example, and the height TM to the upper surface of the claw portion 56 in a state where no force is applied is 2 mm in this example. If the claw portion 56 is pressed with a predetermined force or more against the elasticity, the thickness of the part 50 as the left side in FIG.

図示しない定厚サイド部品は、図７（ｂ）の爪部５６（と５６Ｔ）の無い部品であり、（ａ）では、爪部５６を区画形成しているコ字状の切り込み貫通穴が無く、爪部に相当する領域は定厚部５４と同じにできている。従って、その厚さは前記の板厚Ｔと同じである。定厚サイド部品の右側部は図７のものと同じである。従って、普段、各抽斗２０，４０，６０は左側に付勢されているため、定厚サイド部品に当接している。即ち、筐体との抽斗左側隙間は定厚サイド部品の厚さＴ＝１．４ｍｍである。一方、右側隙間は、既述の通り左右の設定隙間Δは１．５ｍｍであるため、１．５ｍｍ×２−１．４ｍｍ＝１．６ｍｍである。０．８５・Δ≦Ｔ＜Δの関係になるほど両種類のサイド部品は前記設定隙間Δに近い厚さＴを有しており、少なくともこの厚さＴ分の隙間を確保でき、設定隙間Δに近い値の隙間となる。従って、左右の隙間の相違は小さくなる。   A constant-thickness side part (not shown) is a part without the claw portion 56 (and 56T) of FIG. 7B. In FIG. 7A, there is no U-shaped cut through hole that defines the claw portion 56. The region corresponding to the claw portion is made the same as the constant thickness portion 54. Therefore, the thickness is the same as the plate thickness T. The right side of the constant thickness side part is the same as that of FIG. Therefore, the drawers 20, 40, 60 are normally urged to the left and are in contact with the constant thickness side parts. That is, the gap on the left side of the drawer with the casing is the thickness T of the constant thickness side part T = 1.4 mm. On the other hand, the right gap is 1.5 mm × 2−1.4 mm = 1.6 mm because the left and right set gap Δ is 1.5 mm as described above. Both types of side parts have a thickness T close to the set gap Δ so that the relationship of 0.85 · Δ ≦ T <Δ is established, and at least a gap corresponding to the thickness T can be secured. The gap is close. Therefore, the difference between the left and right gaps is reduced.

弾力性サイド部品は図７の形態に限られず、板厚方向の厚さ寸法を弾力的に変化させる構造が種々考えられる。例えば、図７の立壁部５２の左側部において、定厚部５４の下面側の側面視を、その中央部が上方に位置する弓形状にし、爪部５６の存在を不要とした樹脂部品としてもよい。
図６に示す機構では、左右移動板部材１６は施錠時に右方向に駆動される構造であるが、家具の左側にラッチ機構や鍵棒や鍵板を配設して、左右移動板部材を左方向に駆動させる構造としてもよい。この場合は、左側に弾力性サイド部品を装着させ、右側に定厚サイド部品を装着させる。また、家具としては、ワゴンではなく、設置型のキャビネット等でもよい。 The elastic side parts are not limited to the form shown in FIG. 7, and various structures for elastically changing the thickness dimension in the plate thickness direction are conceivable. For example, in the left side portion of the standing wall portion 52 in FIG. Good.
In the mechanism shown in FIG. 6, the left / right moving plate member 16 is driven rightward when locked, but a latch mechanism, a key bar or a key plate is provided on the left side of the furniture, and the left / right moving plate member is moved to the left. A structure that is driven in the direction may be employed. In this case, the elastic side part is mounted on the left side, and the constant thickness side part is mounted on the right side. The furniture may be an installed cabinet or the like instead of a wagon.

本発明は、抽斗を有するワゴンやキャビネット等の家具に利用できる。   The present invention can be used for furniture such as a wagon or cabinet having a drawer.
