  FIG. 1 is a front view showing the external shape of a sink base incorporating a door opening / closing mechanism according to the first embodiment of the present invention, and FIG. 2 is a plan view of the sink base shown in FIG. FIG. 4 is an enlarged sectional view taken along line III-III shown in FIG. 1, and FIG. 4 is an enlarged sectional view taken along line IV-IV shown in FIG.

  With reference to these drawings, a sink base 21 shown as an example of a storage body has a double-opening door 29a and an opening / closing door 29b attached to the front central portion. A flat plate-shaped upper door 28 extending to the full width of the left and right is attached to the upper open surface. A sink is installed behind the upper door 28 at a certain distance. In a space 24a and a space 24b adjacent to both sides of the sink 23, a drawable drawer 27a and a drawer 27b are installed. In addition, between the space 24a, the space 24b, and the sink 23, the rectangular-plate-shaped partition plate 25a and the partition plate 25b which are extended in the back direction from the back surface of the upper door 28 are attached.

  3 and 4, a slide rail 32a including a fixed rail 37a and a moving rail 38a is attached to the surface of the partition plate 25a on the sink 23 side in the horizontal direction. A side plate 34a is fixed to the front end of the moving rail 38a via pins 40a and 40b. As a result, the side plate 34a can move smoothly in the horizontal direction together with the moving rail 38a.

  A front lower end portion of the side plate 34a is connected to a lower portion of the back surface of the upper door 28 via a damper hinge 35a. Accordingly, the upper door 28 is configured to be rotatable so that the front surface thereof faces downward with respect to the side plate 34a via the damper hinge 35a.

  In addition, a small accessory pocket 31 whose upper side is opened is fixed as a storage pocket so as to span between the inner surface of the side plate 34a and the inner surface of the opposite side plate 34b (not shown). Since the accessory pocket 31 is not directly fixed to the upper door 28, the position of the accessory pocket 31 does not change with the rotation of the upper door 28 via the damper hinge 35a.

  In this embodiment, the drawer 27a has a box shape with an open upper surface, and is housed in the space 24a so that the front surface portion thereof approaches the rear surface portion of the upper door 28.

  FIG. 5 is an exploded perspective view showing a state in which the damper hinge 35a is attached.

  Referring to the figure, one end portion of damper hinge 35a is fitted into support piece 42a formed integrally with the lower end of side plate 34a, and its rotation is restricted. On the other hand, the other end of the damper hinge 35a is attached in a state of being fitted to a bracket 41a fixed to the back surface of the upper door 28. Thus, when a force is applied to the upper door 28 so that its front surface rotates downward, the bracket 41a rotates accordingly. At this time, the movement of the damper hinge 35a is gently controlled. Note that the back surface of the upper door 28 is usually fixed to a vertical front surface portion of the side plate 34a by a magnet or the like (not shown).

  6 is a cross-sectional view showing a state in which the door opening / closing mechanism is operated from the state shown in FIG. 3, and FIG. 7 is a plan view of the sink base as viewed from above.

  Referring to the figure, a force is applied to the upper door 28 through a handle or the like (not shown) so as to pull it out. Then, as described above, since the back surface of the upper door 28 and the side plate 34a are fixed by a magnet or the like, they integrally apply force to the moving rail 38a. Since the moving rail 38a and the fixed rail 37a constitute a slide rail 32a, the upper door 28 moves outward smoothly.

  Along with this movement, the accessory pocket 31 also moves with the side plate 34a, and its upper surface is exposed. Kitchen accessories such as kitchen knives are stored in the accessory pocket 31, so that they can be easily taken out from above in this state. In this case, unlike the conventional structure as shown in FIG. 15, the accessory pocket 31 moves in the horizontal direction, so that the degree of openness of the upper surface is increased as shown in FIG. It becomes easy.

  FIG. 8 is a cross-sectional view showing a state when a force is further applied to the upper door 28 from the state of FIG. 6, and FIG. 9 is a plan view corresponding thereto.

  With reference to these drawings, when a force is further applied in the direction of pulling out from the state of FIG. 6 to the upper door 28, the upper door 28 is released from the adhering state with the side plate 34a and is then separated. At this time, due to the action of the damper hinge 35a, the upper door 28 is gently rotated so that the front surface thereof is directed downward, and finally the rear surface is rotated until the rear surface thereof becomes almost horizontal. For this reason, even if the drawer 27a and the drawer 27b housed in the space 24a and the space 24b are pulled forward, the state shown in the figure is obtained and the upper door 28 is not interfered. Since the drawer 27a and the drawer 27b can store kitchen utensils and the like in the same manner as the small pockets 31, and can be easily taken out, the space 24a and the space 24b should be effectively used without making them dead spaces. Is possible.

  FIG. 10 is a cross-sectional view showing a schematic shape of a sink base incorporating a door opening / closing mechanism according to a second embodiment of the present invention, and corresponds to FIG. 3 according to the previous embodiment.

  With reference to the drawings, the description will be focused on differences from the previous embodiment.

  First, the shape of the side plate 34a is different. That is, the lower side of the side plate 34 a is formed as an inclined side 44 so as to rise inward from the upper door 28. The side plate 34a is rotatably connected to the moving rail 38a by a single pin 46a. Further, below the inclined side 44 of the side plate 34a, a support body 45 whose upper surface is in contact with the inclined side 44 is fixed to the partition plate 25a.

  Other configurations are basically the same as those of the previous embodiment.

  FIG. 11 is a schematic sectional view showing an initial state in which the upper door 28 is pulled out from the state of FIG.

  Referring to the figure, when the upper door 28 is pulled out, the side plate 34a also moves outward together with the upper door 28. However, since the side plate 34a is rotatably connected to the moving rail 38a via the pin 46a, the side plate 34a tends to rotate counterclockwise around the pin 46a. However, since the inclined side 44 is in contact with the support body 45, its rotation is restricted, and as a result, the position of the side plate 34a changes so that it gradually inclines downward as the upper door 28 is pulled out. As a result, the accessory pocket 31 fixed to the side plate 34a is also inclined, and it becomes easy to take out the stored items inside.

  12 is a schematic cross-sectional view showing a state in which the upper door 28 is further pulled out from the state of FIG.

  Referring to the figure, the side plate 34a is further tilted downward along with the drawer of the upper door 28, and the accessory pocket 31 is also tilted accordingly. Accordingly, it becomes easier to take out the contents of the accessory pocket 31 than in the state of FIG. If further force is applied to the upper door 28 so that its front surface rotates downward from this state, the upper door 28 moves to the position of the two-dot chain line about the damper hinge 35. In this state, the drawer 27a can be pulled out from the space 24a as indicated by a two-dot chain line. Accordingly, even in this embodiment, the space 24a can be effectively used without making it a dead space.

  In each of the above-described embodiments, the sink base is used as the storage body, but it goes without saying that the present invention can be similarly applied to storage bodies other than the sink base.

  In each of the above embodiments, the door is configured to be inclined at least horizontally. However, the door may be configured to be inclined so that at least the drawer is pulled out.

  Furthermore, in each of the above-described embodiments, the slide rail is used as the moving means, but it may be made movable by a simple support member.

  Further, in each of the above embodiments, a pair of drawers are provided on both sides of the sink. However, the drawers may be either one or not at all.

  Further, in each of the above embodiments, the drawer is open at the top, but the top may be closed.

  Further, in each of the embodiments described above, the accessory pocket is provided as the storage pocket, but this may not be provided, and the range along the door may be narrower.

  Furthermore, in the second embodiment, the inclined side and the support are used as the tilting means, but it goes without saying that other tilting means may be used.

  Further, in each of the above embodiments, the damper hinge is used as the rotating means, but a normal hinge may be used.
