Description

本発明は、ノックダウン式キャビネットに係わり、更に詳しくは使用現場で構成部材を組み立てて完成品とするノックダウン式キャビネットに関するものである。 The present invention relates to a knock-down cabinet, and more particularly to a knock-down cabinet that is a finished product obtained by assembling components at a use site.

従来から、底板、側板、背板、天板及び扉等の構成部材を梱包して使用現場に搬送し、そこで各構成部材を組み立てて完成品とするノックダウン式キャビネットは、各種提供されている。例えば、特許文献１には、底板、底板カバー、両側板、背板、天板及び扉からなる組立式キャビネットが開示されている。この特許文献１には、底板の両側縁及び後縁に沿って係合突条を形成し、両側板の下端に設けた下係合片を前記係合突条に係合するとともに、側方からネジで締め付けて立起状態とし、両側板の上端に設けた上係合片に天板下面の両側に設けた係合突条を係合するとともに、側方からネジで締め付けて連結し、最後に底板と両側板と天板の後端部に背板を嵌合し、内部でネジ止めしてキャビネット本体部を組み立て、最後に扉のヒンジを底板と天板の両側前面に開口したスリットから挿入し、内部でネジ止めする構造が開示されている。尚、前記底板には底板カバーを上方から被せてネジ止め構造を隠蔽し、更に底板の下にはアジャスター機能を備えた基台を連結している。 Conventionally, various knockdown cabinets have been provided in which components such as a bottom plate, a side plate, a back plate, a top plate, and a door are packed and transported to a use site, and each component is assembled into a finished product. . For example, Patent Literature 1 discloses an assembly-type cabinet including a bottom plate, a bottom plate cover, both side plates, a back plate, a top plate, and a door. In Patent Document 1, engaging ridges are formed along both side edges and a rear edge of the bottom plate, and a lower engaging piece provided at a lower end of both side plates is engaged with the engaging ridge, From the side, tightened with screws and engaged with the engagement protrusions provided on both sides of the top plate lower surface to the upper engagement pieces provided on the upper ends of the both sides, Finally, the back plate is fitted to the bottom plate, both side plates, and the rear end of the top plate, screwed inside to assemble the cabinet body, and finally the door hinges are slits that open to the front of both sides of the bottom plate and top plate. The structure which inserts from the inside and is screwed inside is disclosed. The bottom plate is covered with a bottom plate cover from above to conceal the screwing structure, and a base having an adjuster function is connected to the bottom plate.

しかし、特許文献１のキャビネットは、各構成部材の連結にネジを多用しており、施工性に劣るばかりでなく、最後に背板を連結して筐体としての強度を保つ構造であるので、背板を取付けるまでは非常に不安定で、不意に変形する恐れもある。更に、背板が一枚物であるので、通常のキャビネットでは横幅が奥行幅の約２倍あるので、梱包の際に嵩張るという問題がある。底板部が基台、底板及び底板カバーから構成されているため、部品点数が多くコスト高となる。 However, the cabinet of Patent Document 1 uses a lot of screws for connecting each component, and is not only inferior in workability, but also has a structure that maintains the strength as a housing by connecting the back plate at the end. Until the backboard is installed, it is very unstable and may deform unexpectedly. Further, since the back plate is a single piece, the width of the normal cabinet is about twice the depth, so that there is a problem that it becomes bulky when packing. Since the bottom plate portion is composed of the base, the bottom plate, and the bottom plate cover, the number of parts is large and the cost is increased.

特許文献２には、背板を左右に分割し、組立時に中央部で左右の背板を凹凸嵌合によって連結し、底板にそれぞれネジ止めする構造が開示されている。しかし、特許文献２に記載のものは、背板が梱包時に嵩張る問題はないが、底板と両側板、天板と両側板の連結に、各構成部材の端部に嵌入して連結する連結部材を用いるとともに、嵌合部の抜け止めにネジを用いているため。施工性に劣る。 Patent Document 2 discloses a structure in which a back plate is divided into left and right, and the left and right back plates are connected to each other at the center by asperity fitting during assembly, and are respectively screwed to the bottom plate. However, although the thing of patent document 2 does not have the problem that a backplate becomes bulky at the time of packing, it is the connection member which inserts and connects to the edge part of each structural member for the connection of a baseplate and a both-sides board, and a top plate and a both-sides board. Because the screw is used to prevent the fitting part from coming off. Inferior to workability.

一方、特許文献３には、ベースに両側板と背板を上方から順次嵌合して立起状態に保持し、最後に天板を両側板と背板に上方から嵌合し、ベースの上面に底板を重ねて取付ける構造のキャビネットが開示されている。つまり、特許文献３のキャビネットは、ベースの両側縁と後縁に沿って差し込み片を立設し、両側板と背板の下端に設けたスリット状の係合溝を前記差し込み片に嵌合するとともに、背板の両端に前向きに形成した差し込み片を側板の後端のスリット状の係合溝に嵌合し、更に側板をベースにネジ止めし、そして両側板と背板の上端に上向きに形成した差し込み片を、天板の設けた下向きのスリット状の係合溝に嵌合し、天板と側板をネジ止めする構造である。この場合、背板は各隣接する構成部材に嵌合構造のみで保持されている。しかし、この特許文献３のものは、背板の梱包の問題があるとともに、ベースの上面に底板を嵌合してネジ止めする構造であり、やはり部品点数が多く、またネジを使っていることから施工性にも劣るものである。 On the other hand, in Patent Document 3, both side plates and a back plate are sequentially fitted to the base from above and held in an upright state, and finally the top plate is fitted to both the side plates and the back plate from above, Discloses a cabinet having a structure in which a bottom plate is attached in an overlapping manner. That is, in the cabinet of Patent Document 3, the insertion pieces are erected along the both side edges and the rear edge of the base, and the slit-like engagement grooves provided in the lower ends of the both side plates and the back plate are fitted to the insertion pieces. In addition, insert pieces formed forward on both ends of the back plate are fitted into slit-like engagement grooves on the rear end of the side plate, and further, the side plate is screwed to the base, and the upper ends of both side plates and the back plate are directed upward The formed insertion piece is fitted into a downward slit-like engagement groove provided on the top plate, and the top plate and the side plate are screwed. In this case, the back plate is held only by the fitting structure on each adjacent component. However, the thing of this patent document 3 has the problem of packing of a back plate, and also has a structure in which the bottom plate is fitted to the upper surface of the base and screwed, and the number of parts is also large and screws are used. Therefore, it is inferior in workability.

特許文献４には、背板の両側端面に下向きフックを設け、側板の後補強部の内面に形成した係止孔に前記フックを嵌合係止し、両側板と背板とで平面視コ字状となして自立可能な状態とし、両側板の内面側の上下端部に設けたブラケットに、それぞれ天板と底板の側縁を嵌合して受けるとともに、ネジ止めして固定する。ここで、背板の上端は天板の後縁部内面に係合しており、天板によって上方移動が規制されるので、前記フックが係止孔から外れないようになっている。また、扉の上下ヒンジ部材の固定部は天板と底板のスリットにそれぞれ差し込み、内部でネジ止めする構造が開示されている。側板と背板の連結はフックと係止孔の係止手段によるので、簡単に連結することが可能であるが、その他においては天板及び底板を側板にネジ止めし、扉のヒンジ部材を天板と底板にネジ止めしているので、やはり施工性に劣るばかりでなく、筐体としての剛性にも乏しい。 In Patent Document 4, downward hooks are provided on both side end surfaces of the back plate, the hooks are fitted and locked in locking holes formed on the inner surface of the rear reinforcing portion of the side plate, and the two side plates and the back plate are coupled in plan view. It is shaped like a letter so that it can stand on its own, and the brackets provided on the upper and lower ends of the inner surfaces of both side plates are fitted with the side edges of the top plate and the bottom plate, and fixed with screws. Here, the upper end of the back plate is engaged with the inner surface of the rear edge of the top plate, and the upward movement is restricted by the top plate, so that the hook does not come off the locking hole. Moreover, the structure which inserts the fixing | fixed part of the upper-and-lower hinge member of a door in the slit of a top plate and a baseplate, respectively, and is screwed inside is disclosed. The connection between the side plate and the back plate is based on the locking means of the hook and the locking hole, so it can be easily connected. In other cases, the top plate and the bottom plate are screwed to the side plate, and the door hinge member is fixed to the top plate. Since it is screwed to the plate and the bottom plate, it is not only inferior in workability but also in the rigidity as a housing.

そして、本発明に係るノックダウン式キャビネットは、設置現場にて各構成部材を組み立てて完成品とするが、この際に後で組み付ける構成部材によって既に組み付けた構成部材の動きを規制し、最後の構成部材を嵌め殺し構造にすることで、締結ネジを全く必要としないことが特徴である。勿論、完成品が分解され難いように、必要最小限の締結ネジによる固定を併用することは可能である。例えば、最後に嵌め殺し構造で組み付ける構成部材を内部から他の構成部材に締結ネジで固定するというやり方であるが、本発明では限定されない。また、各構成部材は、締結ネジによる連結構造を採用しないので、単体で剛性の高い構造となっており、筒状若しくは箱状の増強構造（袋構造）を部分若しくは全体に採用している。更に、各構成部材を袋構造で構成することにより、強度が確保できるので、板厚を通常の０．７〜０．８ｍｍから０．６ｍｍに薄くでき、それにより軽量化が図れるとともに、材料に掛る費用を抑制できる。 And the knockdown type cabinet according to the present invention assembles each component member at the installation site to make a finished product, but at this time, the movement of the component member already assembled by the component member assembled later is regulated, It is characterized in that no fastening screw is required at all by fitting and structuring the components. Of course, it is possible to use a minimum number of fastening screws together so that the finished product is not easily disassembled. For example, although it is the method of fixing to the other component member from the inside the component member assembled | attached by the last fitting structure by a fastening screw, it is not limited in this invention. In addition, since each component member does not employ a connection structure using fastening screws, it has a single structure with high rigidity, and a cylindrical or box-shaped reinforcing structure (bag structure) is partially or entirely employed. Furthermore, since the strength can be ensured by configuring each component member in a bag structure, the plate thickness can be reduced from the usual 0.7 to 0.8 mm to 0.6 mm, thereby reducing the weight and making it a material. It can control the cost.

And a horizontal flange portion 54 are formed, and a cylindrical upper flange portion 55 is provided at the front edge for reinforcement. The protruding width (horizontal width) of the side flange 53 corresponds to the thickness of the side plate 2, and the protruding width (depth width) of the horizontal flange 54 corresponds to the thickness of the back plate 3. And, at the six corners on both the front and rear sides of the top plate main body 52 and the left and right sides of the rear side, there are engaging claws 56 having elasticity inward and outward, and the corners of the side flanges 53 or the side flanges 54 on both sides thereof. Small downward hooks 57 and 57 are projected. On the other hand, the upper reinforcing portion 24 of the side plate 2 and the upper reinforcing portion 32 of the back plate 3 corresponding to the locking claws 56 are formed by notching the engaging portion 58 at the lower inner edge, and the downward hooks 57, 57 are provided. Locking holes 59, 59 for receiving and engaging are formed in the upper part of the inner edge so as to open upward. The locking claw 56 may be a normal steel material for use within the range of plastic deformation, and includes a vertical piece 61 and a horizontal piece 62 formed by press-forming a claw portion 60 protruding outward, and the top plate main body. A horizontal piece 62 is inserted inward from a notch opening 63 formed in the side surface and the rear surface of the portion 52 and fixed by spot welding to the lower surface of the top plate 5, and the vertical piece 61 is an outer peripheral surface of the top plate main body portion 52. And only the claw portion 60 protrudes outward.

そして、図１６及び図１９に示すように、前記底板１に側板２及び背板３を係止手段と嵌合構造によって連結し、前記扉４を前述のように保持した状態で、上方から前記天板５を落とし込み嵌合する。つまり、前記天板５の天板本体部５２を、前記側板２の上補強部２４と背板３の上補強部３２とで囲まれた空間内に挿入し、前記係止爪５６の爪部６０を前記係合部５８に係止すると同時に、前記下向きフック５７，…を前記係止穴５９に係合させる。このとき、図２０に示すように、前記本体側上ヒンジ部材４２の保持板４４を前記天板５の側鍔部５３で押さえ込み、前記板ばね部材４８の弾性力に抗して前記段落ち部４７に押し込み、前記本体側上ヒンジ部材４２をガタツキなく本体部に保持するのである。前記天板５は、前記係止爪５６が係合部５８に係止することによって嵌め殺し状態で連結され、前記天板本体部５２の外周面と下向きフック５７，…とで上補強部２４，３２の内側板部を挟み込むことによって内外への変位も完全に規制された状態となる。そして、前記天板５が側板２に対して上方へ移動しないことにより、下方への係合によって連結した前記背板３の上方変位を規制し、係合状態を維持するのである。本体側上ヒンジ部材４２の基部は、ばね部５０の先端と前補強部１９の後側内面とにより前後のガタツキが防止され、ばね部５０の上部と天板５の側鍔部５３により上下のガタツキが防止されている。 Then, as shown in FIGS. 16 and 19, the side plate 2 and the back plate 3 are connected to the bottom plate 1 by the engaging means and the fitting structure, and the door 4 is held as described above from above. The top plate 5 is dropped and fitted. That is, the top plate body 52 of the top plate 5 is inserted into a space surrounded by the upper reinforcing portion 24 of the side plate 2 and the upper reinforcing portion 32 of the back plate 3, and the claw portion of the locking claw 56 is inserted. At the same time as 60 is locked to the engaging portion 58, the downward hooks 57 are engaged with the locking hole 59. At this time, as shown in FIG. 20, the holding plate 44 of the main body side upper hinge member 42 is pressed by the side flange portion 53 of the top plate 5, and the stepped portion is resisted against the elastic force of the leaf spring member 48. The main body side upper hinge member 42 is held in the main body without rattling. The top plate 5 is connected in a closed state by the locking claw 56 being locked to the engaging portion 58, and the upper reinforcing portion 24 is connected to the outer peripheral surface of the top plate main body portion 52 and the downward hooks 57. 32, the inward and outward displacement is completely regulated by sandwiching the inner plate portion of 32. And since the top plate 5 does not move upward with respect to the side plate 2, the upward displacement of the back plate 3 connected by downward engagement is restricted, and the engaged state is maintained. The base portion of the main body side upper hinge member 42 is prevented from rattling back and forth by the tip of the spring portion 50 and the rear inner surface of the front reinforcing portion 19, and the upper portion of the spring portion 50 and the side flange portion 53 of the top plate 5 Backlash is prevented.

以上のように各構成部材を組み立てて完成品を得るのであるが、これまで締結ネジを全く使用していない。また、連結構造をフック若しくは爪と孔若しくは穴による係止構造に統一しているので、施工マニュアルが無くても容易に組み立てることができる。また、フック若しくは爪の突出を極力抑えたので、梱包、搬送時における破損を防止できる。また、外観においては、前記縦鍔部２３、側鍔部５３及び横鍔部４５がキャビネット本体部のコーナー部に位置するため、シンプルですっきりとした外観となる。 As described above, the constituent members are assembled to obtain a finished product, but no fastening screw has been used so far. In addition, since the connecting structure is unified as a locking structure with hooks or claws and holes or holes, it can be easily assembled without a construction manual. In addition, since the protrusion of the hook or claw is suppressed as much as possible, it is possible to prevent damage during packing and transportation. Further, in terms of appearance, the vertical flange portion 23, the side flange portion 53, and the horizontal flange portion 45 are located at the corners of the cabinet body, so that the appearance is simple and clean.

また、本発明に係るキャビネットを分解するには、内部から前記係止爪５６の垂直片６１の下端部を工具等で内向きに変形させ、前記爪部６０を前記係合部５８から少しずらせ、全ての係止爪５６を少しずつ外せば、前記天板５を上方へ外すことが可能である。前記天板５が取り除かれると、後は組み立て手順を逆に辿れば容易に書く構成部材を分解することができる。このように本発明に係るキャビネットは、ネジを全く使用してないので、組立・分解が極めて容易である。 In order to disassemble the cabinet according to the present invention, the lower end portion of the vertical piece 61 of the locking claw 56 is deformed inward with a tool or the like from the inside, and the claw portion 60 is slightly shifted from the engagement portion 58. The top plate 5 can be removed upward by removing all the locking claws 56 little by little. When the top plate 5 is removed, the components to be written can be easily disassembled by following the assembly procedure in reverse. As described above, since the cabinet according to the present invention does not use any screws, it is very easy to assemble and disassemble.
