[0015] In order to explain the present invention in more detail, the present invention will be explained hereinafter with reference to the attached drawings.
[0016] Fig. 1 is a view showing a chest 1 including a rail fixing part structure according to an embodiment, and the chest 1 houses clothing and the like.
[0017] The chest 1 is constructed by a wooden chest body 11 and drawings 12 made of a synthetic resin. The above described chest body 11 is formed into a rectangular shape by a bottom plate 14 provided with leg parts 13, side plates 15 and 15 vertically provided at both side portions of the bottom plate 14, a back plate 16 vertically provided at a back side of the above described bottom plate 14, a top plate 17 provided at an upper end of the above described side plates 15 and 15, and the above described back plate 16, as shown in Fig. 1 and Fig. 2. Three of the above described drawers 12 are housed in a front opening of the chest body 11 to be able to be drawn, and are constructed to be able to house and store material goods in the drawers 12.
[0018] The above described drawer 12 is constructed by a drawer body 21 in a rectangular container shape, and a front plate 22 mounted in the state in which it is locked at claw parts 21a and 21a (see Fig. 4) of the drawer body 21, and the above described drawer body 21 and the above described front plate 22 are formed to be semitransparent and constructed to be able to confirm an inside.
[0019] The front plate 22 is formed to be light blue and transparent, and the above described drawer body 21 is formed to be white and transparent. Note that the above described front plate 22 and the drawer body 21 may be formed to be not only semitransparent but also formed to be transparent, or opaque, and in the case of opaque, they can be also colored. At this time, the above described front plate 22 and the above described drawer body 21 are constructed by separate pieces, and therefore, the above described front plate 22 and the above described drawer body 21 can be set to be the same color, or can be set to be different colors. As a result, the appearance quality can be enhanced and variation can be increased.
[0020] A recessed part 23 is provided at a lower portion of the above described front plate 22, and a step part 24 on which a hand can be laid at the time of drawing is formed between the recessed part 23 and the ordinary part. The step part 24 is formed into a bow shape with a central portion projecting upward, and the operating force applied to the step part 24 is applied to a later-described rail 25 which supports the drawer 12 at the chest body 11.
[0021] Metal rails 25, which are supported at a rail not shown provided at an inner surface of each of the side plates 15 and 15 of the above described chest body 11 and slidably support the drawer 12 at the above described chest body 11, are fixed to both side portions of the above described drawer body 21, and the drawer body 21 opened upward has its upper end portion reinforced by the rails 25.
[0022] The rail 25 is formed by folding a long metal plate, and a flange 31 extending toward the above described drawer 12 is provided at the lower edge portion, as shown in Fig. 3. Screw insertion holes 32 and 32 are provided at both endportions of the flange 31 and a raised wall 33 rises from the side edge of the flange 31. A guide surface 34 extending in the direction to separate from the above described drawer 12 is provided at an upper edge of the raised wall 33, and a bent part 35 which is bent downward is formed at a side edge of the guide surface 34. The above described guide surface 34 is notched at one end portion of the rail 25, and a roller 37 a part of which projects from the above described guide surface 34 is rotatably supported at a region of the above described raised wall 33 in a notched part 36.
[0023] Meanwhile, as shown in Fig. 4, the above described drawer body 21 is formed to be opened upward by a rectangular bottom surface 41, a front surface 42 raised from a front edge of the bottom surface 41, side surfaces 43 raised from both side edges of the above described bottom surface 41, and a back surface 44 raised from a rear edge of the above described bottom surface 41. As shown in Fig. 5, an outward extending surface 45 which extends to an outside is formed at upper edges of the above described side surface 43 and the above described back surface 44, and a downward extending surface 46 which extends downward is formed at the extending surface 45. The downward extending surface 46 is constructed to be in surface contact with the raisedwall 33 of the mounted rail 25 to prevent tilt of the rail 25 and form a folded portion at the upper edge portions of the above described side surfaces 43 and the above described back surface 44 to be able to reinforce them.
[0024] The folded portion is constituted of side folded portions 51 formed at the above described both side surfaces 43, and a rear folded part 52 formed over the back surface 44 from the rear portions of both the side surfaces 43, and gaps 53 are formed between the above described both side folded portions 51 and the above described rear folded part 52. As shown in Fig. 5, upper ribs 54 and 54 extending downward from the above described outward extending surfaces 45 and 45 are formed at both ends of the above described side folded parts 51 and both ends of the above described rear folded part 52, and the upper ribs 54 and 54 are also provided to connect to the above described side surfaces 43.
[0025] Besides, on the side surface 43, a lower rib 55 extending in the vertical direction is formed at a lower portion of the above described gap 53 between the above described side folded part 51 and the above described rear folded part 52, and on the front surface 42 side from the above described side folded part 51, the lower rib 55 extending in the vertical direction is formed. Upper ends of both the lower ribs 55 and 55 are provided at a lower position from the position of the height of the lower end of the above described upper rib 54, so that the flange 31 of the above described rail 25 can be vertically sandwiched with the above described upper ribs 54 and the lower ribs 55.
[0026] Support surfaces 61 which extend along the above described flange 31 are integrally formed at upper end portions of the above described lower ribs 55 which support the above described flange 31 from the lower surface side, and the support surface 61 is constructed to be in surface contact with the lower surface of the above described flange 31.
[0027] Besides, cylindrical screw-in parts 71 which extend downward are integrally formed at both end portions at the above described outward extending surfaces 45 of the above described both side folded parts 51 and 51. The screw-in parts 71 are provided at positions corresponding to screw insertion holes 32 and 32 formed at the above described flange 31 in the state in which the above described rail 25 is mounted, and the lower end of the screw-in part 71 is set to have a length dimension that reaches the top surface of the above described flange 31. Thereby, tapping screws which are inserted through the above described screw insertion holes 32 and 32 of the above described flange 31 can be screwed into the above described screw-in parts 71 and 71 in the state in which the above described flange 31 of the above described rail 25 is sandwiched between the above described respective ribs 54 and 55.
[0028] In the above described embodiment with the above construction, on the occasion of fixing the metal rail 25 to the drawer 12 of the synthetic resin, the flange 31 provided at the rail 25 is inserted between the upper ribs 54 and the lower ribs 55 provided at the drawer 12, and the above described flange 31 is vertically sandwiched with both the ribs 54 and 55. Thereby, the above described rail 25 is locked at the drawer 12.
[0029] By only inserting the flange 31 provided at the above described rail 25 between the respective ribs 54 and 55 provided at the drawer 12 as described above, the above described rail 25 can be locked at the drawer 12 in the state in which the above described flange 31 is vertically sandwiched between both the ribs 54 and 55. Thereby, the metal rail 25 can be easily mounted to the drawer 12 of the synthetic resin, and the mounting operation can be easily performed.
[0030] Besides, in the respective ribs 54 and 55 which vertically sandwich the flange 31 provided at the above described rail 25, the support surfaces 61 which extend along the above described flange 31 is provided at the upper end portions of the lower ribs 55 which support the lower surface of the above described flange 31.
[0032] The screw-in parts 71 which extend downward are integrally formed at both end portions at the outward extending surfaces 45 of the both side folded parts 51 and 51 of the above described drawer 12, and the screw-in parts 71 and 71 are provided at the positions corresponding to the screw insertion holes 32 and 32 of the above described rail 25.
[0033] Therefore, the tapping screws are inserted through the screw insertion holes 32 and 32 of the above described flange 31 in the state in which the flange 31 of the above described rail 25 is sandwiched between the respective ribs 54 and 55, and the tapping screws are screwed into the above described screw-in parts 71 and 71, whereby the flange 31 of the above described rail 25 can be screwed in the state in which the flange 31 is sandwiched between the respective ribs 54 and 55 of the above described drawer 12. Thereby, fixation can be further enhanced.
