[Industrial applications]

 The present invention relates to a panel for a prefabricated drawer and a prefabricated drawer using the panel.

[0002]

[Prior Art]

 Conventionally, an assembling drawer 101 as shown in FIG. 11 has been used (see Japanese Utility Model Laid-Open No. 59-15339). As shown in FIG. 12, this drawer 101 is provided with side plates 102 and 103 and a back plate 104 each having a vertically long rectangular cross section and formed of a hollow cylindrical panel. It is composed of a plate 106, a front plate connecting member 107, a bottom plate 110 and the like. The panel has a guide groove 109 on its central outer surface that slides along a guide member (runner) 108 provided on the inner surface of a frame (F in FIG. 11) such as a cabinet, and a bottom plate 110 is inserted below the inner surface 104. The groove 111 is provided. The side plate and the like are usually manufactured by cutting a long panel of a thermoplastic resin extruded product into a predetermined size.

[0003]

[Problems to be solved by the device]

 The conventional panel is manufactured by extrusion molding as a long product, but since the cross-sectional shape is asymmetric, distortion due to sink marks and thermal stress during extrusion molding occurs. Therefore, there is a problem that it is difficult to fit the corner member at the time of assembly, and it is difficult to make the right angle of each member. In particular, since the left side plate 102, the back plate 104, and the right side plate 103 are used by arranging panels of the same shape in a so-called U shape, errors due to warpage are added and become large. Therefore, it is necessary to insert the bottom plate 110 and forcibly apply elastic deformation until the front plate 106 is fixed. The present invention has been made in view of the problems of the conventional assembling pull-out panel, and an object thereof is to provide a panel in which warpage and deformation during molding are small and assembly work is easy. .. Another object of the present invention is to provide a prefabricated drawer that is easy to assemble using such a panel.

[0004]

[Means for Solving the Problems]

 The panel of the present invention is formed of a flexible material and has a hollow tubular upper half having a vertically long rectangular cross section and a lower end of the upper half, and the upper half and the lower half are spaced apart from each other. A hollow cylindrical lower half having a long rectangular cross section and a groove for inserting a bottom plate on the lower inner surface side, a lower end of the upper half and an upper end of the lower half, and And a connecting portion for connecting so as to form a groove, which is formed by one thin plate having flexibility, and the upper half body and the lower half body form a predetermined angle. It is characterized in that it is connected to. In such a panel, it is preferable that a flexible lip is provided so as to project toward the lower surface of the upper half body and the upper surface of the lower half body.

The assembled drawer of the present invention comprises a left and right side plate and a back plate obtained by cutting the panel into a predetermined length, a rear open end of the upper half of the side plate and a side part of the upper half of the back plate. Upper corner member with a right-angled claw member inserted into the open end and the rear open end of the lower half of the side plate and the side open end of the lower half of the back plate, respectively. The lower corner member is provided with a right-angled claw member, a front plate connected to the front ends of the left and right side plates, and a bottom plate inserted into the grooves of the left and right side plates and the back plate.

[0006]

[Action]

 In the panel of the present invention, the upper half body and the lower half body form a predetermined angle. That is, they are connected at the connecting portion so that they have a generally V-shaped cross section. Therefore, the molded panel is less likely to warp or twist in the longitudinal direction, and is straighter than the conventional one. Further, since the connecting portion is a single thin plate, the upper half body and the lower half body can be easily bent so as to be flat during assembly. Therefore, a corner member or the like can be easily inserted. Moreover, even if there is variation in the distortion of each side plate, the side plates and the like try to elastically return in the same direction, so the direction to be corrected is always the same. Therefore, the assembly work is easy. Moreover, since the force to elastically return is constantly applied to the engaging portion with the corner member, it is firmly coupled both during the box-shaped assembly and after the assembly. When the panel of claim 2 is assembled in a drawer and accommodated in a cabinet or the like, the lip elastically abuts the guide member of the cabinet, so that the opening / closing operation of the drawer is smooth. Especially for large-sized panels, it is effective in reducing backlash.

It is a principal part perspective view shown.

A panel 1 shown in FIG. 1 includes a hollow cylindrical upper half body 2 having a vertically long rectangular cross section, and a lower half body connected to the upper half body 2 via a thin plate-shaped connecting portion 3. It is an extrusion molded product of synthetic resin consisting of 4 and. The connecting portion 3 is located on the inner surface side when the panel 1 is assembled as a side plate of a drawer (see FIG. 3) and is substantially flush with the inner surfaces 5 and 6 of the upper half body 2 and the lower half body 4. It is configured. As a result, the lower surface 7 of the upper half body 2, the upper surface 8 of the lower half body 4, and the outer surface 9 of the connecting portion 3 form a U-shaped guide groove 10 that opens toward the outside. Below the inner surface 6 of the lower half body 4, a groove 11 that opens toward the inside is formed. This groove 11 is for inserting and fixing the bottom plate 30 of the drawer as shown in FIG.

Further, the upper half body 2 and the lower half body 4 of the panel 1 are configured such that the upper half body 2 tilts outward by an angle θ, as shown by the imaginary line in FIG. This angle θ is, for example, preferably about 1 to 10 °, particularly about 3 to 6 °. The method of forming such an angle is not particularly limited, but as shown in the side view of FIG. 2 that extremely expresses the angle θ, the entire connecting portion 3a is curved (FIG. 2A), and the middle of the connecting portion 3b is formed. 2), the connecting portion 3c and the upper half body 2 and the lower half body 4 are each bent at an angle of θ / 2. ..

Further, when the panel 1 is vertically long, as shown by the imaginary line in FIG. 1, thin plate ribs 14 and 15 for partitioning the hollow portions 12 and 13 of the upper half body 2 and the lower half body 4 into upper and lower portions, respectively. Is preferably provided. Further, on the lower surface 7 of the upper half body 2 and the upper surface 8 of the lower half body 4, lips 16 and 17 which are substantially parallel to the connecting portion 3 are provided at positions adjacent to the connecting portion 3 so as to face each other. .. As shown in FIG. 4, the lips 16 and 17 elastically slidably contact the inner end surface 23 of the guide member 22 such as the cabinet frame 21 into which the drawer 20 is inserted to smoothly open and close the drawer 20. belongs to . The panel 1 constructed as described above is cut into a predetermined length as shown in FIG. 3, and is used as the left and right side plates 24 and 25 and the back plate 26 of the drawer 20. The drawer 20 shown in FIG. 3 further has corner members 27 and 28 that connect the rear ends of the side plates 24 and 25 and the left and right ends of the back plate 26 at a right angle, and are provided between the front ends of the side plates 24 and 25. A plate 29, a bottom plate 30 serving as a bottom of the drawer, and a front plate connecting member 31 for connecting the back surface of the front plate 29 and the front ends of the side plates 24, 25 are provided.

Two corner members 27 and 28 are provided for each corner, that is, two upper half bodies 2 of the panel, so as not to block the guide groove 10 between the upper half body 2 and the lower half body 4. And an upper corner member 27 connecting the lower half bodies 4 with each other. As shown in FIG. 5, each of the corner members 27 and 28 has a square columnar corner post 32 and a claw member 33A having a U-shaped cross section and extending from two adjacent surfaces of the corner post 32 so as to open at right angles to each other. , 33B. The shape of the claw members 33A and 33B may be any shape as long as it can be fitted firmly with the hollow portions 12 of the upper half body 2 and the lower half body 4, and is not limited to a U-shape. The front-rear dimension a and the left-right dimension b of the corner post 32 are made different from each other, for example, by making b longer than a by the thickness t of the thin plate constituting the panel 1. Therefore, when the side plates 24, 25 and the back plate 26 are assembled, the end surface of one of the inner thin plates abuts the other inner surface, and a gap is less likely to be formed than when the edges are adjacent to each other.

Further, a tapered or wedge-shaped locking projection 35 is provided at the center of each claw member 33A, 33B, and the thin plates outside the side plates 24, 25 and the back plate 26 are as shown in FIG. A square locking hole 36 into which the locking projections 35 fit and engage is formed. Therefore, the claw members 33A, 33B of the corner member 27 can be easily fitted into the hollow portions 12 at the end portions of the side plates 24, 25, etc., and once fitted, by the engagement of the locking projection 35 and the locking hole 36, Combined so that it cannot be easily pulled out.

The side plate 24, (25) or back plate 26 partially shown in FIG. 6 has reinforcing ribs 14 (and 15 in FIG. 1) in the hollow portions 12 of the upper half body 2 and the lower half body. ing. Therefore, the claw portions 33A and 33B of the corner member 27a used for this are divided into upper and lower parts in order to avoid the ribs 14 (15), and the respective claw pieces 33a and 33b are U-shaped in cross section. That is, a gap 34 corresponding to the thickness of the rib 14 (15) is interposed between the pair of upper and lower claw pieces 33a and 33b. Further, in the claw pieces 33a and 33b of the corner member 27a shown in FIG. 6, slits 37 are formed on both sides of the locking projection 35, so that the tongue piece 38 on which the locking projection 35 is placed is easily elastically deformed. ing. Of course, slits may be formed in the claw portions 33A, 33B of the corner member 27 of FIG.

The front plate 29 is a plate material made of, for example, a particle board, and has a groove 30 a into which the bottom plate 30 is inserted in the lower portion on the inner surface side. As shown in FIG. 7, the front plate connecting member 31 includes a fixed plate 39 having substantially the same height as the vertical height of the panel 1, and two upper and lower claw members 40 and 41 protruding rearward from the fixed plate 39. Consists of. The claw members 40 and 41 are substantially the same as the claw portions 33A and 33B of the corner member 27 of FIG. 5, and each has a U-shaped cross section. The upper claw member 40 is fitted in the hollow portion 12a of the upper half body 2, and the lower claw member 41 is fitted in the hollow portion 12b of the lower half body 4. In addition, two holes 42 for attaching to the front plate 29 are formed in the upper and lower portions of the fixed plate 39, and a notch 43 for inserting the bottom plate 30 is formed in the lower end thereof. The upper half body 2 and the lower half body 4 of the panel 1 of FIG. 7 are angled in the opposite direction to that of FIG. 1, that is, the guide groove 10 opens outward. This also has the same effect as the panel of FIG.

The front plate connecting member 44 shown in FIG. 8 is for a side plate composed of a panel having the ribs 14. The front plate connecting member 44 has two pairs of claw members 45 and 46 arranged vertically in the vertical direction, like the corner member 27a of FIG. Instead of the holes for screws, plugs 47 provided with a large number of annular projections having a saw-toothed cross section are provided one above the other. It can be assembled without a driver as it only needs to be fitted into the hole formed in the front plate.

In order to assemble the components constructed as described above into the drawer 20 shown in FIG. 3, first, the back plate 26 and the side plates 24 and 25 are joined by the four corner members 27 and 28 in total, and then the bottom plate 30. Is inserted into the groove 11, and finally the front plate connecting member 31 previously attached to the front plate 29 is assembled to the front ends of the side plates 24 and 25. When the side plates 24, 25 and the back plate 26 are joined together, the panel of the present invention cannot be joined as it is because the upper half 2 and the lower half 4 have an angle θ as shown in FIG. Therefore, one of the claw members opened at right angles to the corner member 27, 33A, is fitted to the back plate 26 side, and then the side plates 24 and 25 and the back plate 26 are respectively bent in the arrow A direction and the arrow B direction. Then, the other side 33B of the claw member is fitted to the side plates 24 and 25 in this state. When, for example, the left side plate 24 is joined to one end of the back plate 26 and the right side plate 25 is attached to the other end, the upper half body 2 and the lower half body 4 may have some angles at the other end, though not as much as at the beginning. There is. Therefore, the right side plate is attached while bending as in the above. The same applies when the front plate 29 is attached after the bottom plate 30 is inserted into the groove 11.

As described above, when the panel of the present invention is used as a side plate or the like, it is necessary to attach it while being somewhat elastically bendable, but the panel itself has less twist and warpage as compared with the conventional panel. Moreover, since it is always inclined in one direction, the direction in which it should be deformed is always in the same direction. Therefore, the assembly work is relatively easy. Further, as the corner member once connected, the upper half 2 tends to fall outward as can be imagined from FIG. 9, so that the catching protrusion 35 and the catching hole 36 are strongly caught and there is some play. However, there is an advantage that the whole is assembled firmly.

FIG. 10 shows an example of a two-tiered drawing-out utilizing the strength and robustness of the connection of such corner portions. This is one in which two panels 51 and 52 are vertically stacked and used as one side plate or back plate. Of course, the bottom plate is inserted only in the groove 11 of the lower panel 52. The corner members are an upper corner member 54 which is inserted into the upper half body 53 of the upper panel 51, an intermediate corner member 57 which is inserted into the lower half body 55 of the upper panel 51 and the upper half body 56 of the lower panel 52. , A lower corner member 59 to be inserted into the lower half body 58 of the lower panel 52. That is, the upper panel 51 and the lower panel 52 are firmly connected by the intermediate corner member 57 (and the front plate).

The panel of the present invention can be extruded from various synthetic resins such as polypropylene, polyethylene, polyvinyl chloride, polycarbonate, polyacetal, nylon, AS resin and ABS resin, or soft metals such as aluminum. It may be manufactured from a flexible material. If desired, a transparent or translucent material may be used. The same applies to the corner member and the front plate connecting member, but in the case of synthetic resin, it is usually manufactured by injection molding or the like. For the bottom plate and the front plate, various materials such as plywood and synthetic resin can be used in addition to particle board. Further, the panel of the present invention can be used for the front plate. In that case, a guide groove (10 in FIG. 1) on the outer surface can be used to attach the handle. Alternatively, the handle may be attached using a lip (16 in FIG. 1).
