Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a chest for storing
clothes, small articles, and so on.
[0003] 2. Description of the Related Art
[0004] Hitherto, a chest is used for storing clothes or small
articles and so on.
[0005] The chest is composed of a chest body and a drawer stored in
the chest body so as to be capable of being drawn out
therefrom.
[0006] The drawer is formed of resin using a metal mold and is
formed into a rectangular container-shape opening upward. Rails are
provided on the side surfaces of the drawer along the upper edges
thereof, and rails which are paired with these rails are extended
in the chest body.
[0007] Accordingly, the drawer can be taken in and out easily by
the movement of the rails on the drawer along the rails in the
chest body.
[0008] However, in the chest in this configuration, it is necessary
to secure spaces for arranging the rails between the side surfaces
of the drawer and the chest body because of the structure in which
the rails are provided on the side surfaces of the drawer.
[0009] Consequently, there arises a problem that the capacity of
the drawer is reduced.
SUMMARY OF THE INVENTION
[0010] In view of such a problem in the related art, it is an
object of the invention to provide a chest in which the storability
of the drawer can be increased.
[0011] In order to solve the above-described problem, a chest
according to claim 1 of the invention is a chest including rails
extending on the side surfaces of a synthetic resin drawer stored
in a chest body in which the rails are provided on the lower
portions of the side surfaces.
[0012] In other words, when forming the synthetic resin drawer with
a metal mold, the side surfaces of the drawer are formed to be
inclined outward as they go upward by a draft angle of the metal
mold, and the side surfaces are inclined so as to be set back
inward as they go downward.
[0013] Therefore, gaps between the chest body and the side surfaces
of the drawer which are formed in conformity with the wide upper
edge are widened as they go downward, and the rails are arranged in
these lower spaces.
[0014] According to claim 2, the rail is formed with a lower fixed
surface to be fixed to the lower surface of the drawer and an
upright surface extending upright from the lower fixed surface to
be fixed to the side surface of the drawer.
[0015] In other words, the lower fixed surface of the rail is fixed
to the lower surface of the drawer and the upright surface
extending upright from the lower fixed surface is fixed to the side
surface of the drawer.
[0016] Accordingly, the corners of the lower portion of the drawer
are reinforced by the lower fixed surface and the upright surface
of the L-shaped rail. Consequently, the rigidity of the drawer can
be enhanced.
[0017] According to claim 3, the widthwise dimension of the drawer
is set to be decreased as it goes downward, so that the opposing
side surfaces are inclined.
[0018] Accordingly, the draft angle of the metal mold at the time
of resin molding can be set, and the drawers can be stored in a
stack.
ADVANTAGE EFFECT
[0019] As described the above, according to the invention of claim
1, the rails can be mounted using the lower spaces formed by the
gaps between the chest body and the side surfaces of the drawer
whose width becomes the largest.
[0020] Therefore, in comparison with the related art in which the
rails are provided on the side surfaces of the wider upper portion,
reduction of the capacity of the drawer can be prevented and
improvement of storability can be achieved.
[0021] According to claim 2 of the invention, the corners of the
lower portion of the drawer are reinforced by the lower fixed
surface and the upright surface of the L-shaped rail.
[0022] Consequently, the rigidity of the drawer can be
enhanced.
[0023] According to claim 3, the widthwise dimension of the drawer
is set to be decreased as it goes downward, so that the opposing
side surfaces are inclined. Accordingly, the draft angle of the
metal mold at the time of resin molding can be set, and the drawers
can be stored in a stack.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] Referring now to the drawings, an embodiment of the
invention will be described. FIG. 1 illustrates a chest 1 in this
embodiment, and the chest 1 is used for storing clothes, small
articles, and so on.
[0033] As shown also in FIG. 2, the chest 1 includes a chest body
11 which constitutes a frame and three rectangular container-shaped
drawers 12, . . . provided in the chest body 11.
[0034] The chest body 11 includes three frame members 21, . . .
connected in the vertically direction, and the frame member 21 at
the bottom is provided with leg portions 23, . . . on a bottom
surface 22 thereof. The upper frame member 21 is provided with a
top plate 24, and the drawers 12, . . . are held between the
respective frame members 21, . . . and between the upper frame
member 21 and the top plate 24 so as to be capable of drawing out
therefrom.
[0035] The frame member 21 is formed of synthetic resin and, as
shown in FIG. 3, the frame member 21 includes a rectangular bottom
plate portion 31 having an opening at the center portion thereof
and supporting columns 32, . . . extending upright from the four
corners of the bottom plate portion 31.
[0036] The supporting column 32 is formed into the shape of a
square pole, and integrally includes a supporting column body 41
extending upright from the bottom plate portion 31, and an insert
portion 42 provided at the upper end of the supporting column body
41. The insert portion 42 is formed to be smaller than the
supporting column body 41 in diameter, and a shoulder 44 is formed
at the upper end of the supporting column body 41 where the insert
portion 42 extends upright from.
[0037] The supporting column 32 is formed into the shape of a
rectangular tube, and the supporting column body 41 is provided at
the lower end thereof with a connecting portion 45 to which the
insert portion 42 of the supporting column 32 which is arranged
below or the leg portion 23 is selectively inserted. Accordingly,
the frame member 21 on the lower side and the frame member 21 on
the upper side can be connected in a state in which the insert
portion 42 of the supporting columns 32 of the frame member 21 on
the lower side are inserted into the connecting portions 45 of the
supporting columns 32 of the frame member 21 on the upper side, and
the shoulders 44 of the supporting column bodies 41 on the lower
side are brought into abutment with the lower ends of the
supporting column bodies 41 on the upper side.
[0038] A lower side surface 51 which is bridged between the lower
ends of the both supporting columns 32, 32 is integrally formed
between the front and rear supporting columns 32, 32 of the frame
member 21, and a metallic inner rail 53 provided with a roller 52
is provided on the lower side surface 51 so as to be bridged
between the supporting columns 32 and 32.
[0039] The drawer 12 held between the left and right supporting
columns 32, 32 of the frame member 21 is formed of synthetic resin
and, as shown in FIG. 4, is formed into a rectangular container
shape having an opening on top. The drawer 12 is formed with a
metal mold which is opened in the vertical direction, and a lateral
dimension H (see FIG. 5) of left and right side surfaces 61, 61 and
the depth dimension of a front surface 62 and a rear surface 63 are
formed to be reduced as they go downward by a draft angle.
Accordingly, the opposed left and right side surfaces 61, 61 and
the opposed front surface 62 and rear surface 63 are inclined and
are set to be widened in inner dimension as they go upward, whereby
the drawers are adapted to be capable of being stored in a
stack.
[0040] The side surfaces 61, 61 each are provided with a metallic
outer rail 65 which is paired with the inner rail 53 on the lower
portion thereof. The outer rail 65 includes a lower fixed surface
73 to be fixed to a shoulder portion 72, as shown in FIG. 5, formed
on the side portion of a lower surface 71 of the drawer 21 and an
upright surface 75 extending upright from the lower fixed surface
73 to be fixed to a set-back portion 74 at the lower portion of the
side surface 61 of the drawer 21 and, as shown in FIG. 4 and FIG.
6, the lower corner at the front end of the upright surface 75 is
held in a state of being interposed between a lower locking portion
76 formed on the side surface 61 and the side surface 61. The upper
corner at the front end of the upright surface 75 is prevented from
moving forward by an angular-shaped projection 77 protruded from
the side surface 61.
[0041] Then, as shown in FIG. 4 and FIG. 7, the lower fixed surface
73 of the outer rail 65 is held in a state of being interposed
between locking strips 81, . . . formed into an L-shape in
cross-section provided on the lower surface 71 of the drawer 21 and
the lower surface 71 and, as shown in FIG. 4, a roller 82 is
provided at the rear end of the upright surface 75. Accordingly, as
shown in FIG. 8, the roller 52 provided on the inner rail 53
rotates along an upper surface guide 83 provided on the outer rail
65, and the roller 82 provided on the outer rail 65 rotates along
an upper surface guide 84 provided on the inner rail 53, so that
the movement of the drawer 21 is facilitated.
[0042] In this embodiment configured as described above, when the
synthetic resin drawer 12 is formed by the metal mold, the side
surfaces 61 of the drawer 21 are formed to be inclined outward as
they go upward by the draft angle of the metal mold, and the side
surfaces 61 are inclined so as to be set back inward as they go
downward. Therefore, gaps K between the chest body 11 and the side
surfaces 61 of the drawer 21 which are formed in conformity with
the wide upper edge are widened in width as they go downward, and
the both rails 53 and 65 are arranged in the lower spaces.
[0043] In this manner, the both rails 53 and 61 can be mounted
using the lower spaces formed by the gaps K between the chest body
11 and the side surfaces 61 of the drawer 12.
[0044] Therefore, in comparison with the related art in which the
both rails 53 and 61 are provided on the side surfaces 61 of the
wider upper portion, reduction of the capacity of the drawer 21 can
be prevented and improvement of storability can be achieved.
[0045] The outer rail 65 is formed with the lower fixed surface 73
and the upright surface 75 which is formed into an L-shape in cross
section, the lower fixed surface 73 is fixed to the lower surface
71 of the drawer 21 and the upright surface 75 extending upright
from the lower fixed surface 73 is fixed to the side surface 61 of
the drawer 21.
[0046] Accordingly, the corners of the lower portion of the drawer
21 are reinforced by the lower fixed surface 73 and the upright
surface 75 formed into an L-shape. Therefore, the rigidity of the
drawer 21 can be enhanced.
[0047] In addition, since the lateral dimension H of the drawer 12
is set to be reduced as it goes downward, the draft angle of the
metal mold at the time of resin molding can be set, and the
plurality of drawers 12, . . . can be stored in a stack.
