Description

  The present invention relates to assembling-type storage furniture constructed by assembling a plurality of plate members into a box shape.

  As a structure for assembling the plate material in constructing the assembly-type storage furniture suitable for knockdown or the like, for example, Patent Document 1 discloses an engagement protrusion formed by raising the left and right ends of the rear side forward, and the rear end of the side plate. The structure which engages with the engagement recessed part formed in the reinforcing material arrange | positioned in the up-down direction in a part and connects a backplate and a side plate is disclosed. The engaging protrusion has an upright plate portion that rises forward from the back surface, and an elastically deformable inclined surface portion that is inclined rearward and inwardly from the upright plate portion, and the back plate and the side plate have the inner surfaces of each other. In such a state that the engagement protrusion and the engagement recess are brought into contact with each other and the side plate is rotated 90 degrees around the contact portion as an axis, the engagement protrusion is formed as shown in FIG. It can be connected by being accommodated along the wall surface of the engaging recess. At this time, the side edge portion of the back plate and the rear edge portion of the side plate are pressure-bonded by the elastic force of the engaging protrusion.

  Thus, the assembly-type storage furniture disclosed in Patent Document 1 can be easily connected by rotating the side plate relative to the back plate.

Japanese Patent No. 5109154

  However, in the assembly position, the back plate and the side plate are restricted in the horizontal direction by the engagement protrusions and the engagement recesses, but the direction along the edge portions (engagement edge portions) adjacent to each other. In other words, it is difficult to say that the configuration is such that the relative movement in the vertical direction can be sufficiently regulated, and the configuration for regulating the relative movement of the back plate and the side plate in the direction along the engagement edge is improved. There is room.

  In order to cope with this problem, it is conceivable to attach a part of the back plate and the side plate separately using a fastening device such as a screw, but this leads to an increase in the number of parts and the number of assembly processes, resulting in a decrease in assembly efficiency. It will be connected.

  An object of the present invention is to solve the above-described problems. Specifically, in a configuration that can be connected by relatively rotating plate members adjacent to each other including a back plate and a side plate, An object of the present invention is to provide an assembly-type storage furniture with good assembly efficiency while restricting relative movement in the direction along the engagement edge between the plate members.

  The present invention also aims to solve these problems together.

  In order to achieve this object, the present invention takes the following measures.

  That is, the assembly-type storage furniture of the present invention is formed by assembling a plurality of plate materials into a box shape, and engages any one of the plate materials adjacent to each other among the plurality of plate materials, from the position where they are engaged. As the plate member is relatively rotated toward the assembly position, one of the plate members is wound around the other to deepen the engagement state, and a connecting portion is formed at the engagement edge of both plate members, respectively. Then, either one of the two plate members is inserted into the other connecting portion from the direction substantially orthogonal to the extending direction of the engaging edge using the relative rotation, and the extending direction of the engaging edge It has the movement control part which controls the relative movement of the said board | plate materials in.

  According to this configuration, the plate member is engaged with each other via the connecting portion and the plate member is relatively rotated toward the assembly position, and either one of the two plate members is moved to the other connecting portion by the movement restricting portion. On the other hand, since it is inserted from the direction substantially perpendicular to the extending direction of the engaging edge, after connecting the plate materials at the assembly position, both the plate materials at the assembly position are not fastened with a fastening tool such as a screw. The relative movement of the plate material in the extending direction of the engagement edge can be easily restricted. Therefore, it is possible to improve the assembly efficiency by reducing the number of parts and assembly steps while restricting the relative movement of the plate members in the direction along the engagement edge.

  As a specific configuration, any one of the plates that are connected to each other via the connecting portion and the movement restricting portion and the relative movement is restricted is substantially orthogonal to the extending direction of the engaging edge portions of the two plate members. And the other one of the plate members can be inserted with the engagement protrusion, and the length of the engagement edge in the extending direction of the engagement protrusion. And an engagement recess having a width dimension that allows the movement of the engagement protrusion with the relative rotation, and the movement restriction portion is configured by the engagement protrusion and the engagement recess. Composed.

  Alternatively, as another configuration of the movement restricting portion in the case where the plate materials that are connected and relatively restricted by the movement via the connecting portion and the movement restricting portion are the back plate and the side plate, respectively, the back plate and the side plate Either one of them extends in the horizontal direction substantially orthogonal to the engagement edge between the back plate and the side plate, and a plate material receiver for placing the plate material serving as the top plate or the bottom plate is formed on the upper edge portion or the lower edge portion. And the other one of the back plate and the side plate is capable of inserting the front end portion of the plate material receiver, opens corresponding to the length of the front end portion in the vertical direction, and receives the plate material receiver accompanying the relative rotation. An engagement recess having a width dimension that allows the movement of the distal end of the plate member is provided, and the movement restricting portion is configured by the distal end of the plate material receiver and the engagement recess.

  When the plate members that are connected and controlled relative to each other via the connecting portion and the movement restricting portion are a back plate and a side plate, respectively, other plate materials such as a top plate and a bottom plate are used as the back plate using the connecting portion. And at least one of the top plate and the bottom plate has a notch-like fitting groove formed at a position corresponding to the connecting portion at the assembly position. It is preferable that the mating groove is fitted to the connecting portion, and the connecting portion is sandwiched from both sides to be connected to the back plate and the side plate.

  Furthermore, when the fitting groove is formed in the bottom plate, any one of the bottom plate and the back plate can be used to easily position the bottom plate connected to the back plate and the side plate using the connecting portion in the vertical direction. Either one has a horizontal protrusion that protrudes substantially horizontally toward the other, and either the bottom plate or the back plate has a horizontal recess that can be engaged with the horizontal protrusion at the assembly position. It is preferable.

  In particular, when the plate members that are connected to each other and controlled relative to each other via the connecting portion and the movement restricting portion are a back plate and a side plate, respectively, the shelf plate can be suitably attached without narrowing the accommodation space. In order to do so, it is preferable that a shelf plate mounting hole for arranging the shelf plate in the accommodation space is formed in the connecting portion.

  On the other hand, when the plate members that are connected and restricted relative to each other via the connecting portion and the movement restricting portion are a back plate and a side plate, respectively, a configuration that allows a top plate to be suitably attached to the back plate is simplified In order to achieve, while providing a top plate receiver for placing the top plate on the upper edge of the back plate, on the rear end surface of the top plate is formed a protrusion having an insertion portion along the vertical direction, By forming an insertion recess into which the insertion portion can be inserted into the back plate, and inserting the rear portion of the top plate on the top plate receiving portion while inserting the insertion portion of the protruding portion into the insertion recess, the top plate is A configuration in which the positioning is performed in the vertical direction is preferable.

  Since the present invention has the configuration described above, the movement restricting portion inserts either one of the two plate members into the other from the direction substantially orthogonal to the extending direction of the engaging edge portion, and the engagement edge portion. The relative movement in the extending direction can be easily and effectively suppressed, the work required for the assembly can be reduced, and the assembly efficiency can be improved.

Similarly, it is configured by assembling a bottom plate 4 which is a plate material and is attached between the lower ends of the side plates 2 in a box shape, and forms an accommodation space sp1 therein. In the following description, the side on which the furniture body Fa1 is open is the front (front side), the side on which the back plate 1 is located is the back (rear side), and the side on which the top plate 3 is located is the upper side (upper side). The side on which the bottom plate 4 is located is the lower side (lower side), and the accommodation space sp1 side surrounded by the back plate 1, the side plate 2, the top plate 3 and the bottom plate 4 constituting the furniture body Fa1 is the inner side (inner side), The anti-accommodation space sp1 side of the furniture body Fa1 is outward (outside), the right from the front to the rear is the right (right), and the left is the left (left).

  The back plate 1 is formed by appropriately bending a single metal plate material by plastic deformation processing (for example, sheet metal processing). As shown in FIG. 2, the right end portion and the left end portion are respectively forward. The left end face 1c and the right end face 1d are formed by bending substantially at right angles to each other, and back plate side connecting portions 10 and 10 as connecting portions are formed at the front end portions thereof. Further, the upper end portion (upper edge portion) is bent inward at a substantially right angle to form the upper end surface 1a, and the tip end portion thereof is bent downward at a substantially right angle to form the upper inner wall portion 11a. A top plate receiver 11b as a plate material receiver is formed by bending forward at a substantially right angle. The top plate receiver 11b has an end in the left-right direction cut into a tapered shape to form a tapered portion 11b1. The inclination angle of the taper part 11b1 is adjusted to an angle substantially equal to a suitable inclination angle of the side plate 2 arranged with respect to the back plate 1 when the back plate 1 and the side plate 2 described later are connected. Further, the lower end portion (lower edge portion) is bent inward at a substantially right angle to form the lower end surface 1b, the front end portion is bent upward, and the front end portion is bent forward at a substantially right angle to serve as a plate material receiver. A bottom plate receiver 12 is formed. Moreover, the notch part 11a1 as an insertion recessed part opened toward the downward direction is formed in the right-and-left both ends side among the upper end parts of the backplate 1. As shown in FIG. The notch (slit) 11a1 is formed by notching a part of the left and right end portions of the upper inner wall portion 11a in a substantially rectangular shape, and the upper surface of the top plate receiver 11b from the upper edge 11a2 of the notch 11a1. The length in the up-down direction is substantially equal to the length in the up-down direction at the insertion portion of the protrusion described later.

  Specifically, the back plate side connecting portion 10 formed at the left end portion is a first parallel substantially parallel to the face plate portion 1x of the back plate 1 by bending the tip end portion of the left end surface 1c to the left at a substantially right angle. A portion 10a is formed, and a tip portion thereof is bent forward at a substantially right angle to form a first orthogonal portion 10b that is substantially orthogonal to the face plate portion 1x. Further, by bending the distal end portion of the first orthogonal portion 10b to the left at a substantially right angle, a second parallel portion 10c that is substantially parallel to the first parallel portion 10a is formed, and the distal end portion is substantially perpendicular to the rear side. Is bent to form a second orthogonal portion 10d that is substantially parallel to the first orthogonal portion 10b, and has a bowl shape that is substantially J-shaped in plan view. The second parallel portion 10c is configured to be shorter than the first parallel portion 10a, and the second orthogonal portion 10d is configured to be shorter than the first orthogonal portion 10b. In a state where the second parallel portion 10c is coupled to the side plate 2 at the assembly position, A predetermined gap is formed between the second orthogonal portion 10d and the face plate portion 2x of the side plate 2 (see FIG. 3). In addition, an engagement window 10bc serving as an engagement recess is formed at the upper end portion of the back plate side connecting portion 10 and opens to the first orthogonal portion 10b and the second parallel portion 10c. The engagement window 10bc is opened corresponding to an engagement claw 21c (see FIG. 3) described later, and will be described in detail later.

  Further, a plurality of shelf board mounting holes 10b1 for attaching the shelf board 5 (see FIG. 1) are formed in the first orthogonal portion 10b in a line in the vertical direction. The right end surface 1d and the back plate side connecting portion 10 formed at the right end portion are configured symmetrically with the back plate side connecting portion 10 described above at the left end portion.

  In the back plate 1, the edge including the left end surface 1 c and the edge including the right end surface 1 d become the engaging edges 10 x and 10 x with the side plates 2 and 2, respectively.

As shown in FIG. 3, the side plate 2 is formed into a substantially rectangular shape by appropriately bending a single metal plate material by plastic deformation processing (for example, sheet metal processing), and constitutes a side surface of the furniture body Fa1. To do. The upper and lower ends and the front and rear ends are bent inward at substantially right angles to form an upper end surface 2a, a lower end surface 2b, a rear end surface 2c, and a front end surface 2d, respectively. The edge portion including the rear end surface 2 c becomes the engagement edge portion 21 x with the back plate 1.

  The side plate 2 arranged at the left end portion of the back plate 1 is formed with a side plate side connecting portion 21 as a connecting portion engageable with the back plate side connecting portion 10 at the rear end portion. Specifically, the side plate side coupling portion 21 bends the front end portion of the rear end surface 2c forward at a substantially right angle to form a parallel portion 21a parallel to the face plate portion 2x of the side plate 2, and further further extends the front end portion to the left side. By being bent at a right angle to form an orthogonal portion 21b that is substantially orthogonal to the parallel portion 21a, it is configured to have a substantially U-shape in plan view. The orthogonal part 21b has a notch at its upper end, and from the front end at the upper end of the parallel part 21a, a position corresponding to the engagement window 10bc (see FIG. 2) formed in the back plate side connecting part 10 described above. Furthermore, an engaging claw 21c as an engaging convex portion having a substantially rectangular shape in side view extends forward. In such a side plate side connecting portion 21, a shelf plate mounting hole 21ab is formed at a position overlapping the shelf plate mounting hole 10b1 of the back plate side connecting portion 10 at the assembly position. In addition, the shelf mounting hole 21ab of the side plate side connecting portion 21 is set to be slightly larger than the shelf mounting hole 10b1 of the back plate side connecting portion 10. Therefore, an attachment auxiliary tool (not shown) such as a hook for attaching the shelf board 5 (see FIG. 1) is hardly restricted by the shelf board attachment hole 21ab, and is exclusively positioned by the shelf board attachment hole 10b1. Be regulated. The side plate 2 disposed at the right end portion of the back plate 1 has a bilaterally symmetric configuration with the above-described side plate 2 disposed at the left end portion of the back plate 1.

  Further, a reinforcing member 22 is attached to the front end portion of the side plate 2 so as to extend in the vertical direction. Also in the reinforcing member 22, a plurality of shelf board mounting holes 22a are formed in the vertical direction at height positions corresponding to the shelf board mounting holes 21ab. In addition, the dimension of this shelf board attachment hole 22a is set substantially equal to the shelf board attachment hole 10b1 of the backplate side connection part 10. FIG. Brackets 23 and 24 are respectively attached to the rear end side of the reinforcing member 22 by arc welding or the like among the upper end portion and the lower end portion of the side plate 2. As shown in FIG. 3, the bracket 23 at the upper end includes a horizontal piece 23a extending horizontally from the face plate 2x of the side plate 2 and standing pieces 23b and 23c standing up from front and rear ends of the horizontal piece 23a. . The horizontal piece 23a is formed with a screw insertion hole 23a1 for screwing to the top plate 3. The bracket 24 at the lower end of the side plate 2 is composed of a horizontal piece 24a extending horizontally from the lower end of the reinforcing member 22 and upright pieces 24b and 24c standing up from front and rear ends of the horizontal piece 24a. Among these, the standing piece 24b in the front is tapered toward the face plate portion 2x, and a screw hole 24a1 for screwing to the bottom plate 4 is formed in the horizontal piece 24a. Furthermore, an engagement piece 26 that protrudes inward is formed at a corner portion on the front and upper side of the side plate 2. The engaging piece 26 includes a plate-like portion parallel to the up-down direction, and can receive a force in the up-down direction by its small opening, and thus has a high strength in the up-down direction.

  As shown in FIG. 4 (a), the back plate side connecting portion 10 is formed with an opening that is opened around the front end portion so as to go outward in the left-right direction. 21 can be inserted into the back plate side connecting portion 10 and the engaging claw 21c can be protruded from the engaging window 10bc inward from a direction substantially orthogonal to the extending direction of the engaging edge portions 10x, 21x. . When initially inserted into the engagement window 10bc, the engagement claw 21c is located on the first parallel portion 10a side of the engagement window 10bc, and from this state, the engagement claw 21c can be moved to the second parallel portion 10c side. The width dimension of the engagement window 10bc is configured so as to be able to. The vertical dimension of the engagement window 10bc is substantially equal to the vertical length of the engagement claw 21c, and the upper or lower end of the engagement claw 21c is at the upper or lower edge of the engagement window 10bc. By making contact with each other, the relative movement along the engaging edge portions 10x and 21x of the back plate 1 and the side plate 2 is restricted, and in this embodiment, the engaging claw 21c and the engaging claw 21c are engaged. The window 10bc becomes the movement restricting portion A. In addition, illustration of the top-plate receptacle 11b of the side plate 2 is abbreviate | omitted in Fig.4 (a).

  When the side plate 2 is connected to the back plate 1 as described above, as shown in FIG. 4B, the engagement edge portions 10x and 21x are brought close to each other, and the side plate 2 is connected to the back plate 1 with respect to each other. The face plate portions 1x and 2x are arranged so as to be inclined so as to face each other. At this time, the side plate 2 is disposed along the tapered portion 11b1 of the top plate receiver 11b provided on the back plate 1 in plan view, and the engaging claw 21c is on the first parallel portion 10a side of the engaging window 10bc. To be inserted. The inclination angle of the taper portion 11b1 of the top plate receiver 11b is set to an angle at which the engagement claw 21c can be smoothly inserted into the engagement window 10bc, and this taper portion 11b1 can be used as a guide when assembling.

  Then, with the back plate side connecting portion 10 and the side plate side connecting portion 21 engaged in this manner, the front end side of the side plate 2 is relatively rotated in the direction indicated by the arrow X, and as shown in FIG. Is moved to an assembly position substantially orthogonal to the back plate 1. During the movement, the back plate side connecting portion 10 and the side plate side connecting portion 21 are elastically deformed with each other, and the back plate side connecting portion 10 wraps around the side plate side connecting portion 21 and the engagement state deepens. In the assembly position, the parallel portion 21 c of the side plate side connecting portion 21 abuts against the second orthogonal portion 10 d of the back plate side connecting portion 10, and the rear end surface 2 c of the side plate side connecting portion 21 is the first parallel portion of the back plate side connecting portion 10. Abutting along the portion 10a, the side plate side connecting portion 21 is accommodated in the back plate side connecting portion 10, and the back plate side connecting portion 10 and the side plate side connecting portion 21 in such an engaged state are used for furniture. The rigidity of the main body Fa1 is ensured. At this time, as shown in FIG.5 (b), the engaging claw 21c is located in the 2nd parallel part 10c side in the engaging window 10bc. In this way, the back plate 1 and the side plate 2 are connected orthogonally, and the extension direction of the engaging edge portions 10x and 21x is determined by the movement restricting portion A composed of the engaging claw 21c and the engaging window 10bc. The movement relative to the parallel direction, that is, the vertical direction is restricted, and the side plate 2 is attached to the back plate 1. The side plate 2 is similarly attached to the right end side of the back plate 1. In addition, in FIG.4 (b) and FIG.5 (b), the backplate side connection part 10 and the sideplate side connection part 21 have shown typically the thickness etc. of the constituent material which comprises these.

The bottom plate 4 is formed by appropriately bending a single metal plate material by plastic deformation processing (for example, sheet metal processing or the like), and a reinforcing material 42 extending in the width direction at the front end portion on the back surface side. A reinforcing member 41 extending in the front-rear direction is provided slightly inside the left and right ends. Further, fitting grooves 40 that are cut out substantially equally along the outer shape of the back plate side connecting portion 10 are formed at the left and right ends of the face plate portion 4x of the bottom plate 4, and as shown in FIG. The back plate side connecting portion 10 and the side plate side connecting portion 21 in the combined state can be sandwiched by the fitting grooves 40 from both sides. Then, the front end portion of the bottom plate 4 is pushed downward, the standing piece 24b of the bracket 24 is inserted into the engagement hole 43 (see FIG. 7) formed in the reinforcing member 42 on the back surface side of the bottom plate 4, and the standing piece 24c is inserted. Along the rear end surface of the reinforcing member 42, the reinforcing member 42 of the bottom plate 4 is pressed against the bottom plate receiver 25 of the side plate 2 and the horizontal piece 24 a of the bracket 24. Thereafter, the bracket 24 is screwed to the reinforcing member of the bottom plate 4 by using the screw holes 24a1 with screws inserted into the screw insertion holes 44b formed in the bottom plate 4. Here, as shown in FIG. 7, two reinforcing members 41 extending in the front-rear direction are attached to the back surface of the bottom plate 4 so as to be separated in the width direction. The reinforcing member 41 includes a base portion 41a facing the face plate portion 4x of the bottom plate 4x, an extending portion 41b extending from the left and right ends of the base portion 41a toward the face plate portion 4x, and a tip of the extending portion 41b from the tip of the extending portion 41b to the face plate portion 4x. A horizontal recess 41b1 is formed which is open toward the bottom plate receiver 12 of the back plate 1 by cutting out the rear end of the extended portion 41b. When the bottom plate 4 is pushed down horizontally as described above, the horizontal recess 41b1 sandwiches the bottom plate receiver 12 from above and below, and the upper or lower surface of the bottom plate receiver 12 contacts the upper or lower edge of the horizontal recess 41b1. By contacting, the rear end portion of the bottom plate 4 is configured to be regulated in the vertical direction. The opening edge of the horizontal recess 41b1 is tapered so that the bottom plate receiver 12 can be easily inserted. Note that a screw hole (not shown) for attaching the base portion 6 shown in FIG. 1 is formed in the bottom plate 4, and this screw hole is covered with a lid portion 44a. In this way, the bottom plate 4 is attached to the back plate 1 and the side plate 2.

  As shown in FIG. 8, the top plate 3 is formed in a substantially rectangular shape by appropriately bending a single metal plate material by plastic deformation processing (for example, sheet metal processing or the like). The top surface of the furniture body Fa1 is Configure. The left and right ends and the front and rear ends are bent inward at substantially right angles to form a front end face 3a, a rear end face 3b, a right end face 3c, and a left end face 3d, respectively. In addition, by bending the distal end portions of the right end surface 3c and the left end surface 3d inward at substantially right angles, an inner parallel portion 3c1 substantially parallel to the face plate portion 3x of the top plate 3 is formed, and the distal end portions are further raised upward. By bending at a substantially right angle, an inner orthogonal portion 3c2 that is substantially orthogonal to the face plate portion 3x is formed. In addition, protrusions 30 are provided at both left and right ends of the rear end surface 3b of the top plate 3. The protruding portion 30 has a substantially L-shaped cross section having a plate-like insertion portion 30a extending in parallel with the vertical direction and a reinforcing portion 30b substantially orthogonal to the insertion portion 30a. The insertion portion 30a has a right end surface. The portions to be 3c and the left end surface 3d are formed by extending rearward from the rear end surface 3b, and the reinforcing portion 30b is formed by extending the inner parallel portion 3c1 rearward from the rear end surface 3b. Note that the shape of the protrusion 30 is not limited to a substantially L-shaped cross section, and may be a substantially I-shaped cross section including only the insertion portion 30a. Strength can be increased.

  Furthermore, the top plate 3 includes a reinforcing material 32 extending in the left-right direction at the front portion on the back surface side, and the reinforcing material 32 is attached to the back surface of the face plate portion 3x by means such as spot welding. The reinforcing member 32 is spaced apart from the face plate portion 3x of the top plate 3 by a predetermined distance, and extends toward the face plate portion 3x from the front and rear ends of the base portion 32a.

The front end surface 3a has its tip end bent further rearward and upward at substantially right angles, and the portion bent upward is in contact with the first extension portion 32c. In addition, the left and right ends of the plate material constituting the front end face 3c are bent substantially at right angles toward the rear to form front end portions 33 constituting the front end portions of the right end face 3c and the left end face 3d. The front end portion 33 is configured in a substantially L shape in side view by a front end region 33a extending along the front ends of the right end surface 3c and the left end surface 3d and a rear region 33b extending rearward from the lower end of the front end region 33a.

  The top plate 3 is formed by cutting out portions corresponding to the reinforcing material 32 except for the front end portion 33 of the right end surface 3c and the left end surface 3d forming the side surfaces to form a side opening 34 that is an opening. . A top plate engaging groove 31 extending in the front-rear direction for engaging with the engaging piece 26 (see FIG. 3) is formed by the side opening 34 and the front end portion 33 on the front side of the side opening 34.
