BACKGROUND OF THE INVENTION
[0001] The present invention relates to a rail fixing part
structure of a drawer that houses clothing and the like.
[0002] Conventionally, chests are used on an occasion of housing
clothing and the like.
[0003] The chest is constructed by a chest body made of a synthetic
resin and a drawer made of a synthetic resin which is housed in the
chest body to be able to be drawn.
[0004] When the chest body is changed to a wooden one in such a
chest, the drawer made of a synthetic resin slides in contact with
the wooden chest body. This brings about the problem of worsening
slide of the drawer and reducing the operability.
[0005] In order to solve the problem, it is conceivable that a
drawer part supported by the chest body is constructed by a metal
rail.
[0006] However, in such a drawer, the metal rail has to be mounted
to the drawer made of the synthetic resin, thus requiring labor and
efforts.
[0007] The present invention is made in view of the above
conventional problems, and an object of the present invention is to
provide a rail fixing part structure easy in mounting
operation.

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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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 end portions 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.
[0029] 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 raised wall 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] Thereby, the fixed state of the above described flange 31
can be stabilized.
[0038] 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.
[0039] 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.
[0040] As explained thus far, in the rail fixing part structure of
claim 1 of the present invention, on the occasion of fixing the
metal rail to the drawer of the synthetic resin, the flange
provided at the rail is inserted into the ribs provided at the
drawer, whereby the rail can be locked at the drawer in the state
in which the above described flange is vertically sandwiched with
the ribs.
[0041] Thereby, the metal rail can be easily mounted to the drawer
of the synthetic resin, and the mounting operation can be easily
performed.
[0042] Besides, in the rail fixing part structure of claim 2, in
the ribs which vertically sandwich the flange provided at the rail,
the support surfaces which extend along the above described flange
are provided at the upper end portions of the ribs which support
the lower surface of the above described flange, and therefore, the
fixed state of the flange can be further stabilized.
[0043] Further, in the rail fixing part structure of claim 3, the
screw-in parts in which the screws inserted through the flange are
screwed are provided at the drawer, and the flange of the above
described rail can be fixed in the state in which the flange is
sandwiched between the ribs of the drawer by screwing the above
described screws into the above described screw-in parts. Thereby,
fixation can be enhanced.
[0044] The present invention may be embodied in other specific
forms without departing from its spirit or essential
characteristics. The described embodiments are to be considered in
all respects only as illustrative and not as restrictive. The scope
of the invention is, therefore, indicated by the appended claims
and their combination in whole or in part rather than by the
foregoing description. All changes that come within the meaning and
range of equivalency of the claims are to be embraced within their
scope.
