DETAILED DESCRIPTION OF THE INVENTION

[0023] Fig. 1 shows a cross-sectional view of a storage unit 10 according to an embodiment to which the drawer structure of the present invention is applied, as seen from the right side, and Fig. 2 shows a perspective view of the main parts of the storage unit 10, as seen from above and the front. In the drawings, the front of the storage unit 10 is indicated by an arrow FR, the right side of the storage unit 10 is indicated by an arrow RH, and the top of the storage unit 10 is indicated by an arrow UP.

[0024] 1 and 2, the storage unit 10 according to this embodiment is provided with a rectangular box-shaped cabinet 12, which is provided with a front panel 12a, a back panel 12b (rear panel), a left panel 12c, and a right panel 12d. A sink 14 is provided at the top of the cabinet 12, and piping 14A extends from the bottom end of the sink 14.

[0025] A rectangular opening 12A is formed in the vertical middle of the front plate 12a of the cabinet 12, and the opening 12A opens the interior of the cabinet 12 to the front. A first rail 16 is fixed to the inner surfaces of the left side plate 12c and the right side plate 12d of the cabinet 12, and the first rail 16 extends in the front-to-rear direction behind the lower end of the opening 12A. A substantially semi-cylindrical stopper 12B is fixed to the inner surface of the right side plate 12d of the cabinet 12, and the stopper 12B is disposed behind and above the first rail 16 on the right side, and protrudes to the left.

[0026] The cabinet 12 is provided with a drawer 18 (see FIGS. 3 to 5), which is provided with a front panel 18a, a back panel 18b (rear panel), a left panel 18c, a right panel 18d, and a bottom panel 18e (lower panel). The drawer 18 is supported by a first rail 16 of the cabinet 12, and the drawer 18 is movable in the front-to-rear direction while movement (including tilting) in the up-down and left-to-right directions relative to the first rail 16 is restricted. Therefore, the drawer 18 can be moved forward along the first rail 16 to be pulled out, and moved backward along the first rail 16 to be closed (the opening 12A of the cabinet 12 is closed by the front panel 18a).

[0027] In the drawer 18, the back panel 18b is smaller in vertical dimension than the front panel 18a, and the left and right side panels 18c, 18d are also smaller in vertical dimension than the back panel 18b. In the drawer 18, a cylindrical gallery pipe 18A is suspended between the left and right ends of the upper end of the back panel 18b and the front panel 18a, and the gallery pipe 18A extends in the front-to-rear direction above the left and right side panels 18c, 18d of the drawer 18. A storage space 20 serving as a storage section is formed within the drawer 18, and the storage space 20 is a space behind the front panel 18a and above the bottom panel 18e of the drawer 18. A roughly rectangular parallelepiped storage box 22 can be attached to the left and right parts of the front end of the storage space 20, and the interior of the storage box 22 is open upward.

[0028] A pair of U-shaped plate-like mounting brackets 24 (see FIG. 7(A)) are provided on the right side of the rear of the drawer 18, and the pair of mounting brackets 24 are spaced apart in the left-right direction. One side of a fixing bracket 24A, which is a plate-like member with an L-shaped cross section, is fixed by screwing to the lower and middle parts (the middle part in the up-down direction) of the mounting bracket 24, and the other side of the fixing bracket 24A at the lower part of the mounting bracket 24 is fixed from below to the bottom plate 18e of the drawer 18 by screwing, and the other side of the fixing bracket 24A at the middle part of the mounting bracket 24 is fixed from the rear to the back plate 18b of the drawer 18 by screwing. The mounting bracket 24 is arranged vertically in the left-right direction, and the upper part of the mounting bracket 24 extends forward near the upper side of the back plate 18b of the drawer 18.

[0029] Second rails 26 (see FIG. 7(B)) are supported on the upper sides of the mounting brackets 24, with the left-hand second rail 26 extending in the front-rear direction on the right side of the left-hand mounting bracket 24, and the right-hand second rail 26 extending in the front-rear direction on the left side of the right-hand mounting bracket 24. An inner rail 26A is provided on the second rails 26, and the inner rail 26A is fixed to the upper sides of the mounting brackets 24 by screw fastening. The inner rail 26A is fitted into an outer rail 26B (a so-called linear rail), and with the left-hand second rail 26, the outer rail 26B is arranged to the right of the inner rail 26A, and with the right-hand second rail 26, the outer rail 26B is arranged to the left of the inner rail 26A. The outer rail 26B is supported by the inner rail 26A and is longer than the inner rail 26A, and the outer rail 26B is movable in the front-to-rear direction while being restricted from moving up and down and left and right (including tilting) relative to the inner rail 26A. Cylindrical shafts 26C serving as mounting parts that form an elastic fitting structure are fixed to the front and rear of the outer rail 26B by screw fastening, and the shaft 26C of the left second rail 26 protrudes to the right, and the shaft 26C of the right second rail 26 protrudes to the left.

[0030] An inner drawer 28 (see Figures 4 and 6) is supported above the second rail 26. The inner drawer 28 is provided with a front plate 28a, a back plate 28b (rear plate), a left side plate 28c, a right side plate 28d, and a bottom plate 28e (lower plate), and the front plate 28a, back plate 28b, left side plate 28c, and right side plate 28d are arranged from above to below the bottom plate 28e, and the right side plate 28d is aligned in the left-right direction with the right side plate 18d of the drawer 18. Resin catches 30 serving as attachment portions that form an elastic fitting structure are fixed to the left-side and front corners, left-side and rear corners, right-side and front corners, and right-side and rear corners of the bottom plate 28e of the inner drawer 28, and the catches 30 protrude downward. The catch 30 is provided with a fitting frame 30A with a C-shaped cross section, and the fitting frame 30A has an axial direction extending left and right, and the interior is open to the bottom. Rectangular plate-shaped guide pieces 30B are integrally provided on both circumferential ends of the fitting frame 30A, and the left-right distance between the pair of guide pieces 30B increases as they extend downward.

[0031] The shaft 26C of the second rail 26 (outer rail 26B) is fitted into the fitting frame 30A, and an elastic diameter-contracting force of the fitting frame 30A is applied to the shaft 26C. As a result, the catch 30 is attached to the shaft 26C, and the inner drawer 28 is attached to the second rail 26 (outer rail 26B). When the shaft 26C is inserted into the fitting frame 30A, the shaft 26C passes between the pair of guide pieces 30B from below, and the fitting frame 30A is elastically expanded in diameter by the shaft 26C.

[0032] The inner drawer 28 is movable in the front-to-rear direction integrally with the outer rail 26B of the second rail 26 relative to the inner rail 26A of the second rail 26, thereby enabling the inner drawer 28 to move in the front-to-rear direction relative to the drawer 18. When the inner drawer 28 is moved forward relative to the drawer 18, the inner drawer 28 is moved to the right portion of the upper part of the storage space 20 of the drawer 18, and can be moved to the vicinity of the rear side of the storage box 22 on the right side of the storage space 20. When the drawer 18 is in the pulled-out state, when the inner drawer 28 is moved rearward (pushed) relative to the drawer 18, the inner drawer 28 is positioned from the rear part to the rear side of the storage space 20. When the drawer 18 is closed, the back panel 28b of the inner drawer 28 abuts against the stopper 12B of the cabinet 12, restricting the rearward movement of the inner drawer 28 and positioning the inner drawer 28 in the foremost position relative to the drawer 18.

[0033] A stay 32 having an L-shaped cross section is provided at the rear of the inner drawer 28 in the left-right middle. The upper portion of the stay 32 is fixed to the bottom plate 28e of the inner drawer 28 from below by screws, and the rear portion of the stay 32 abuts against the back plate 28b of the inner drawer 28 from the front. A cylindrical magnet 32A is fixed to the lower end of the rear portion of the stay 32, and the magnet 32A protrudes forward. The magnet 32A is magnetically attracted to the back plate 18b of the drawer 18 from the rear side. When the magnet 32A is magnetically attracted to the back plate 18b of the drawer 18, the inner drawer 28 is movable in the front-rear direction together with the drawer 18 while being positioned at the foremost position relative to the drawer 18. When the magnet 32A is separated from the back plate 18b of the drawer 18 against the magnetic force, the inner drawer 28 is movable in the front-rear direction relative to the drawer 18.

[0034] A guard 28A having an L-shaped cross section is fixed to the rear left corner above the bottom plate 28e of the inner drawer 28, with the front portion of the guard 28A extending in the left-right direction and the right portion of the guard 28A extending in the front-to-back direction. The front portion of the guard 28A is integral with the left side plate 28c of the inner drawer 28, and the left side plate 28c of the inner drawer 28 does not have a portion above the bottom plate 28e behind the front portion of the guard 28A. The right portion of the guard 28A is integral with the back plate 28b of the inner drawer 28, and the back plate 28b of the inner drawer 28 does not have a portion above the bottom plate 28e to the left of the right portion of the guard 28A. For this reason, the inside of the guard 28A is open to the rear and left side, and when the inner drawer 28 is moved rearward, the piping 14A inside the cabinet 12 is positioned inside the guard 28A, preventing the inner drawer 28 from interfering with the piping 14A.

[0035] Next, the operation of this embodiment will be described.

[0036] In the storage unit 10 configured as described above, a bulky space 20A serving as a first storage section is formed in the storage space 20 of the drawer 18 to the left and front of the inner drawer 28, and even when the inner drawer 28 is positioned in the front-most position relative to the drawer 18, the bulky space 20A is not divided into upper and lower sections by the inner drawer 28. Furthermore, a horizontally elongated space 20B serving as a second storage section is formed in the storage space 20 of the drawer 18 at the position of the inner drawer 28, and when the inner drawer 28 is positioned in the front-most position relative to the drawer 18, the horizontally elongated space 20B is divided into upper and lower sections by the inner drawer 28. Then, as the inner drawer 28 is moved rearward relative to the drawer 18, the horizontally elongated space 20B becomes continuous in height with the bulky space 20A and is no longer divided from the bulky space 20A. Therefore, because the storage space 20 is not divided by the inner drawer 28, it is possible to reduce inner corners in the storage space 20, making the storage space 20 easier to clean.

[0037] Here, the inner drawer 28 is attached to the drawer 18 via the mounting bracket 24 and the second rail 26. Therefore, unlike when the inner drawer 28 is supported by the side panels of the cabinet 12 or the side panels of the drawer 18, the position of the inner drawer 28 within the drawer 18 can be adjusted by adjusting the positions of the mounting bracket 24 and the second rail 26 relative to the drawer 18, thereby increasing the degree of freedom in arranging the inner drawer 28 within the drawer 18. Furthermore, because the inner drawer 28 is supported by the drawer 18 and not by the cabinet 12, it is easy to add the inner drawer 28 to the storage unit 10. Moreover, because the inner drawer 28 is supported by the second rail 26 and not by a pulley, the slidability of the inner drawer 28 can be increased.

[0038] Furthermore, the mounting bracket 24 is attached to the back plate 18b and bottom plate 18e of the drawer 18, outside the storage space 20 of the drawer 18. As a result, the drawer 18 can be provided with a second rail 26 and an inner drawer 28 via the mounting bracket 24, and the inner drawer 28 can be slidably supported in the drawer 18. By attaching the mounting bracket 24 to the back plate 18b and bottom plate 18e of the drawer 18, the support rigidity of the mounting bracket 24 by the drawer 18 can be increased, and the support rigidity of the second rail 26 and therefore the inner drawer 28 by the drawer 18 can be increased. In addition, the horizontally elongated space 20B of the storage space 20 can be prevented from being divided into left and right by the mounting bracket 24 and the second rail 26, which increases the degree of storage freedom in the horizontally elongated space 20B and improves the utilization efficiency of the storage space 20. Moreover, the mounting brackets 24 and second rails 26 that support the inner drawer 28 are made difficult to see from the front and above of the storage unit 10 by the inner drawer 28, giving the inner drawer 28 a floating appearance and preventing the design of the storage unit 10 from being affected even if the strength of the mounting brackets 24 and second rails 26 is increased. Furthermore, because the mounting brackets 24 are attached to the outside of the drawer 18, the mounting brackets 24 and the screws for attaching the mounting brackets 24 to the drawer 18 are prevented from being positioned in front of the back panel 18b of the drawer 18.

[0039] Moreover, by providing a pair of mounting brackets 24 and a pair of second rails 26, the support rigidity of the inner drawer 28 by the drawer 18 can be effectively increased. Furthermore, since the left and right parts of the inner drawer 28 are supported by the mounting brackets 24 and the second rails 26, the support rigidity of the entire inner drawer 28 in the left-right direction can be increased.

[0040] Furthermore, the shaft 26C of the second rail 26 (outer rail 26B) is elastically fitted into the catch 30 (fitting frame 30A) of the inner drawer 28, thereby attaching the inner drawer 28 to the second rail 26. Therefore, unlike when the inner drawer 28 is fastened to the second rail 26 with screws, the inner drawer 28 can be moved downward to be attached to the second rail 26, and the inner drawer 28 can be moved upward to be removed from the second rail 26, making it easy to attach and detach the inner drawer 28 to and from the second rail 26. This allows the drawer 18 and the inner drawer 28 to be handled separately during assembly, installation, and maintenance (service) of the storage unit 10 in the factory, improving the handleability of the drawer 18 and the inner drawer 28. Furthermore, since the inner drawer 28 can be easily removed from the second rail 26, it is possible to prevent the inner drawer 28 from colliding with the surrounding cabinets 12 and drawers 18 when removing the inner drawer 28 from the second rail 26.

[0041] Moreover, by moving one of the front and rear sides of the inner drawer 28 upward, one of the front and rear shafts 26C of the second rail 26 is released from within the catch 30 on one of the front and rear sides of the inner drawer 28, and then the inner drawer 28 is tilted by the principle of leverage, with the mounting bracket 24 or the second rail 26 as the fulcrum, and the other of the front and rear shafts 26C of the second rail 26 is released from within the other of the front and rear catch 30 on the front and rear sides of the inner drawer 28. This makes it even easier to remove the inner drawer 28 from the second rail 26.

[0042] In this embodiment, the mounting bracket 24, second rail 26, and inner drawer 28 are arranged on the right side of the drawer 18. However, the mounting bracket 24, second rail 26, and inner drawer 28 may be arranged in any left-right position on the drawer 18.

[0043] Furthermore, in this embodiment, the mounting bracket 24 is attached to the back plate 18b and bottom plate 18e of the drawer 18. However, it is only necessary that the mounting bracket 24 is attached to at least one of the back plate 18b and bottom plate 18e of the drawer 18.

[0044] In this embodiment, a sink 14 is provided on the upper part of the cabinet 12. However, a sink or a stove may be provided on the upper part of the cabinet 12, and the storage unit 10 may be used as furniture. [Explanation of symbols]
