Description

Technical Field

[0001] The present invention relates to a double-sided drawer structure that can be pulled out from both the front side and the back side of a storage space.

Background Art

[0002] This type of double-sided drawer structure is convenient because dishes can be washed in the kitchen side and stored in the drawer, and when serving meals, the drawer can be pulled out from the dining side to serve the washed dishes, and it is preferably applied to counter kitchens and has become popular.

[0003] For example, Patent Document 1 discloses a drawer device that can be pulled out from both the front side and the back side with a single drawer rail. In the drawer device described in this Patent Document 1, rollers 4 that rotate forward and backward are disposed at two locations in the front and rear of the left and right side plates 31 and 32, and rails 5 are disposed on the left and right inner side surfaces of the storage body facing the rollers 4. A stopper 6 is provided such that a stop portion protrudes from the rail 5 by contact with the roller 4 that passes first, and the subsequent roller 4 is prevented from passing when it contacts the stop portion, thereby preventing further pulling out of the drawer (see Claim 1 of the claims of Patent Document 1, paragraphs

[0010] to

[0019] of the specification, FIGS. 1 to 3 of the drawings, etc.).

[0004] However, the drawer device described in Patent Document 1 has a problem that since it must be pullable from both sides, the rail 5, which is a movable part, cannot be covered with the drawer's curtain plate, and the mechanism parts such as the rail and the roller are exposed, resulting in a poor appearance.

[0005] In addition, since the drawer device described in Patent Document 1 must be able to be pulled out from both sides, a stopper for stopping the drawer body in a state where it is accommodated in the storage space cannot be provided. When the drawer is closed, there is a problem that it will jump out from the opposite side due to inertia. The stopper 6 of the drawer device described in Patent Document 1 is a stopper that catches the roller 4 located at the end of the drawer 3 to prevent the drawer 3 from being completely pulled out and detached from the storage body 1, and it is not a stopper for preventing the drawer 3 from jumping out from the opposite side due to the inertia force when closing the drawer 3 from the opposite side of the storage body 1.

[0006] As a method for solving such a problem, it is conceivable to attach a push-in type catch or the like to suppress the inertia force when closing. However, since it is necessary to pull out the drawer body from both sides, when the inertia force exceeds a certain force, it cannot prevent the drawer body from jumping out from the opposite side.

[0007] Moreover, the drawer device described in Patent Document 1 is a mechanism that enables pulling out from both sides with a single drawer rail, which has a complicated structure, is thick, difficult to conceal, and is likely to malfunction when dust or the like is caught in the mechanism, and is also expensive.

[0008] In addition, Patent Document 2 discloses a double-pull drawer structure in which the drawer rail is divided into upper and lower two stages and the drawer rail is concealed by a front plate. The double-pull drawer structure described in this Patent Document 2 is provided with restricting means 47, 49, 86, 88 for restricting the relative movement in the front-rear direction between the pulled-out front plate 10 and the storage box body 8 in response to the connected state of the front plate 10 pulled out outward and the storage box body 8, so that rattling or collision of the front plate against the storage box body when storing the storage box body can be prevented.

[0009] However, although the double-pull drawer structure described in Patent Document 2 can conceal the drawer rails when the drawer is stored, it has not been able to solve the problem that the drawer pops out from the opposite side when the drawer is closed. In addition, the double-pull drawer structure described in Patent Document 2 also has the problem that the front plate 9 will also open if the drawer pops out.

[0010] Moreover, the double-pull drawer structure described in Patent Document 2 also has the problems that the structure is complex, and like the drawer device described in Patent Document 1, it is prone to failure when debris is caught and is expensive.

Summary of the Invention

Problems to be Solved by the Invention

[0012] Therefore, the present invention has been devised in view of the above-described problems, and its object is to provide a double-sided drawer structure that simplifies the drawer mechanism and can be concealed as much as possible, and can prevent the drawer from popping out from the opposite side due to inertial force when the drawer is closed.

Means for Solving the Problems

[0013] The double-sided drawer structure according to the first invention is a double-sided drawer structure that can be pulled out from both the front side and the back side of the storage space. The drawer includes a drawer body and a U-shaped outer frame provided outside the drawer body in a plan view. An outer drawer rail is provided between the outer frame and the side plate of the storage space, and an inner drawer rail is provided between the outer frame and the drawer body. The outer drawer rail and the inner drawer rail are provided with a soft close mechanism for preventing the drawer from popping out to the opposite side by inertial force when the drawer is closed.

[0014] The double-sided drawer structure according to the second invention is, in the first invention, characterized in that the soft close mechanism includes a tension spring for pulling back the state where the rail is open and a damper for applying a load against the restoring force of the tension spring.

[0015] The double-sided drawer structure according to the third invention is, in the first invention or the second invention, characterized in that the side frame of the drawer body has an inverted L-shaped cross-section that covers the inner drawer rail from above.

[0016] The double-sided drawer structure according to the fourth invention is, in any one of the first to third inventions, characterized in that a flap door is provided on the back side of the storage space.

[0017] The double-sided drawer structure according to the fifth invention is, in the fourth invention, characterized in that the left and right lower ends of the drawer body are structured to avoid the hinge of the flap door.

[0018] The double-sided drawer structure according to the sixth invention is, in any one of the first to fifth inventions, characterized in that the storage space is provided under the countertop of a counter kitchen.

[0019] The double-sided drawer structure according to the seventh invention is, in the sixth invention, characterized in that the height from the lower end of the outer frame to the worktop of the counter kitchen is ensured to be 105 mm or more.

Advantages of the Invention

[0020] According to the first to seventh inventions, since the drawer rail, which is a drawer mechanism, is divided into two pairs of two rails, namely an outer drawer rail and an inner drawer rail, the mechanism of one rail becomes simple, not only improving the durability of the drawer mechanism, but also making each rail thinner and enabling the rail to be hidden from the human eye level. Also, according to the first to seventh inventions, since a soft-close mechanism is provided to prevent the drawer from popping out to the opposite side due to inertial force when the drawer is closed, even when the drawer is forcefully closed, it can be prevented from popping out to the opposite side due to inertial force.

[0021] In particular, according to the third invention, since the side frame of the drawer body has an inverted L-shaped cross-section that covers the inner drawer rail from above, the inner drawer rail can be hidden almost invisibly from the human eye level.

[0022] In particular, according to the fourth invention, since a flap door is provided on the back side of the storage space, the double-sided drawer structure can be hidden by the flap door when the drawer is not pulled out.

[0023] In particular, according to the fifth invention, since the left and right lower ends of the drawer body are structured to avoid the hinges of the flap door, there is no obstacle to the access to the back side of the drawer, and the effective utilization of the space can be achieved without reducing the accommodation height of the drawer.

[0024] In particular, according to the sixth and seventh inventions, since the height from the countertop of the counter kitchen to the lower end of the outer frame is ensured to be 105 mm or more, the height for installing the backsplash can be ensured, and the drawer can be pulled in and out with cooking utensils such as bowls placed on the countertop, so that it will not interfere with the cooking operation.

Embodiments for Carrying Out the Invention

[0026] Hereinafter, embodiments for implementing the double-sided drawer structure to which the present invention is applied will be described in detail with reference to the drawings.

[0027] First, with reference to FIGS. 1 to 10, the double-sided drawer structure 1 according to an embodiment of the present invention will be described. FIG. 1 is a view seen from the kitchen side when the double-sided drawer structure 1 according to an embodiment of the present invention is applied to the counter kitchen 10, and FIG. 2 is a view seen from the dining side when the double-sided drawer structure 1 according to the present embodiment is applied to the counter kitchen 10. As shown in FIGS. 1 and 2, in the double-sided drawer structure 1 according to an embodiment of the present invention, a storage space 12 is provided under the counter 11 at the back of the kitchen of the counter kitchen 10, and an example of a double-sided drawer structure that can be pulled out from both the front kitchen side (K side) and the back dining side (D side) will be described.

[0028] Note that reference numeral 13 in FIG. 1 is the worktop 13 of the counter kitchen 10, and reference numeral 14 is the sink 14. Further, reference numeral 15 in FIG. 2 is a flap door 15 that closes so that the double-sided drawer structure 1 cannot be seen from the dining side (D side).

[0029] As shown in FIGS. 3 to 5, the double-sided drawer structure 1 according to the present embodiment includes a drawer 2, a pair of left and right outer drawer rails 3, 3 for slidably pulling out the drawer 2, and a pair of left and right inner drawer rails 4, 4. FIG. 3 is a front view of the double-sided drawer structure seen from the kitchen side (K side), and FIG. 4 is a rear view of the double-sided drawer structure seen from the dining side (D side). FIG. 5 is a partial vertical cross-sectional view mainly showing the drawer rails 3, 4 of the double-sided drawer structure 1. Note that reference numeral 16 is the side plate 16 of the storage space 12, and reference numeral 17 is the bottom plate 17 of the storage space 12.

[0030] (Drawer) The drawer 2 is composed of an outer frame 5 made of a wood material, a metal such as an aluminum alloy or a steel plate, or a resin as shown in FIG. 6, a drawer body 6 made of a wood material or a resin as shown in FIG. 7, and the like. Here, the wood material refers to wood including solid wood, plywood with a veneer or the like pasted on the surface, a laminated veneer lumber, a glued laminated timber, or a material obtained by decomposing wood into elements of various sizes, solidifying them with an adhesive or the like, and then reconstructing them. FIG. 6 is a perspective view showing only the outer frame 5 of the drawer 2 of the double-sided drawer structure 1, and FIG. 7 is a perspective view showing only the drawer body 6 of the drawer 2 of the double-sided drawer structure 1.

[0031] As shown in FIG. 6, the outer frame 5 is a U-shaped frame body in plan view, and is composed of a curtain plate 50, a pair of left and right frame beams 51, 51 having a vertically long rectangular cross section and erected perpendicular to the plate surface of the curtain plate 50, and the like. Then, as shown in FIG. 5, an outer drawer rail 3 is interposed between the frame beam 51 and the side plate 16 of the storage space 12, and the outer frame 5 is configured to be slidable on the side plate 16 of the storage space 12 by the outer drawer rail 3.

[0032] As shown in FIG. 7, the drawer body 6 is composed of a curtain plate 60, a pair of left and right side frames 61 having an inverted L-shaped cross section, a back plate 62, a bottom plate 63, and the like, and has a function of placing and storing the contents on the bottom plate 63. Then, as shown in FIG. 5, an inner drawer rail 4 is interposed between the side frame 61 and the frame beam 51, and the drawer body 6 is configured to be slidable on the outer frame 5 by the inner drawer rail 4.

[0033] (Drawer rail) In the double-sided drawer structure 1 according to the present embodiment, the outer drawer rail 3 and the inner drawer rail 4 have the same configuration. Of course, it goes without saying that the outer drawer rail 3 and the inner drawer rail 4 may have different configurations. However, by making the outer drawer rail 3 and the inner drawer rail 4 have the same configuration as in the double-sided drawer structure 1 according to the present embodiment, the number of parts can be reduced and cost reduction can be achieved.

[0034] As shown in Fig. 5, the outer drawer rail 3 is composed of an outer rail 30, a middle rail 31, and an inner rail 32. The outer rail 30 is fixed inside the side plate 16 of the storage space 12, and the inner rail 32 is fixed outside the frame beam 51 of the outer frame 5.

[0035] Similarly, as shown in Fig. 5, the inner drawer rail 4 is composed of an outer rail 40, a middle rail 41, and an inner rail 42. The outer rail 40 is fixed inside the frame beam 51 of the outer frame 5, and the inner rail 42 is fixed outside the side frame 61 of the drawer body 6.

[0036] (Soft close mechanism) Also, as shown in Fig. 8, the outer drawer rail 3 and the inner drawer rail 4 are equipped with a soft close mechanism 7. This soft close mechanism 7 mainly includes a spring coil 33(43) which is a tension spring and an oil damper 34(44), and has a function of preventing the drawer 2 from popping out to the opposite side due to inertia when the drawer 2 is closed.

[0037] Specifically, as shown in Fig. 8, the outer rail 30(40) and the middle rail 31(41) are connected by a spring coil 33(43), and a load is applied to the spring coil 33(43) in the direction corresponding to the restoring force of the spring coil 33(43) by the oil damper 34(44). Therefore, in the state where the drawer 2 is closed, that is, when the middle rail 31(41) is at a distance of a certain value or less from the outer rail 30(40), the inner rail 32(42) is pulled back by the spring coil 33(43) with respect to the outer rail 30(40).

[0038] At this time, since a load is applied to the spring coil 33(43) in the direction corresponding to the restoring force of the spring coil 33(43) by the oil damper 34(44), the inner rail 32(42) is slowly pulled back by the spring coil 33(43) with respect to the outer rail 30(40).

[0039] That is, as shown in Fig. 9, when the drawer 2 is forcefully closed from the dining side (D side) in the direction of arrow A, there is a risk that the outer frame 5 will pop out in the direction of arrow B due to its inertial force. However, not only does the oil damper 34 (44) weaken the inertial force that causes the outer frame 5 to pop out in the direction of arrow B, but also the outer rail 30 of the outer drawer rail 3 and the middle rail 31 are connected by a spring coil 33. Therefore, the middle rail 31 and the inner rail 32 are pulled back by the restoring force of the spring coil 33, and the outer frame 5 fixed to the inner rail 32 is also pulled back in the direction of arrow C (see also Fig. 5). Fig. 9 is a functional explanatory diagram showing the function of the soft-close mechanism.

[0040] At this time, due to the function of the oil damper 34, the outer frame 5 is slowly and softly pulled back in the direction of arrow C. Therefore, it is possible to prevent the outer frame 5 from being forcefully pulled back by the restoring force of the spring coil 33 and the drawer body 6 from being opened in the opposite direction due to its inertial force (see also Fig. 8).

[0041] Similarly, as shown in Fig. 9, when the drawer 2 is forcefully closed from the kitchen side (K side) in the direction of arrow D, the drawer body 6 will pop out in the direction of arrow E due to its inertial force. However, since the outer rail 40 of the inner drawer rail 4 and the middle rail 41 are connected by a spring coil 43, the middle rail 41 and the inner rail 42 are pulled back by the restoring force of the spring coil 43, and the drawer body 6 fixed to the inner rail 42 is also pulled back in the direction of arrow F (see also Fig. 5).

[0042] At this time, due to the function of the oil damper 44, the drawer body 6 is slowly and softly pulled back in the direction of arrow F. Therefore, it is possible to prevent the drawer body 6 from being forcefully pulled back by the restoring force of the spring coil 43 and the outer frame 5 from being opened in the opposite direction due to its inertial force (see also Fig. 8).

[0043] (Drawer height) As shown in Fig. 10, the height of the drawer 2 is H1 = 105 mm or more from the worktop 13 to the lower end of the curtain plate 50 of the outer frame 5. Fig. 10 is a diagram showing the height of the drawer 2 from the worktop 13. By ensuring this predetermined height H1 = 105 mm or more, a back guard can be installed on the back of the worktop 13, and the drawer 2 can be pulled in and out with cooking utensils such as bowls placed on the worktop 13, without interfering with the cooking operation.

[0044] (The left and right lower ends of the drawer body) Also, as shown in Fig. 5, the bottom plate 63 of the drawer body 6 that serves as a drawer on the dining side of the drawer 2 does not reach the left and right ends of the drawer body 6, and the left and right lower ends of the drawer body 6 are structured to avoid the hinge 15a of the flap door 15. Therefore, the double-sided drawer structure 1 does not hinder the pulling in and out of the drawer 2 on the dining side, and effectively utilizes the space without reducing the accommodation height of the drawer 2.

[0045] [Function and Effect of the Embodiment] The double-sided drawer structure 1 according to the embodiment of the present invention described above is a double-sided drawer structure that can be pulled out from both the front side (kitchen side) and the back side (dining side). The drawer rail, which is a drawer mechanism, is divided into two pairs of two rails: an outer drawer rail 3 and an inner drawer rail 4. Therefore, the mechanism of one rail becomes simple, the risk of getting complicated and having garbage stuck is reduced, and the durability of the drawer mechanism is improved.

[0046] Also, in the double-sided drawer structure 1, the pair of left and right side frames 61 of the drawer body 6 has a reverse L-shaped cross-section that covers the inner drawer rail 4 between the frame beam 51 of the outer frame 5 and the side frame 61 from above. Therefore, the inner drawer rail 4 can be concealed so that it can hardly be seen from above, which is the line of sight of people, when pulling out the drawer 2 from both the kitchen side and the dining side.

[0047] In addition, the double-sided drawer structure 1 is provided with a flap door 15 that blocks the double-sided drawer structure 1 from being seen from the dining room side, so that when the drawer 2 is not pulled out, the double-sided drawer structure 1 can be completely concealed from being seen from the dining room side.

[0048] As described above, the left and right bottom ends of the drawer body 6 are designed to avoid the hinges 15a of the flap door 15. Therefore, the double-sided drawer structure 1 allows the drawer 2 to be easily inserted and removed from the dining area, and makes effective use of the space without compromising the storage height of the drawer 2.

[0049] Furthermore, in the double-sided drawer structure 1, the aforementioned soft-close mechanism 7 is provided on both the outer drawer rail 3 and the inner drawer rail 4. Therefore, even if the drawer 2 is forcefully closed from either the kitchen side or the dining room side, the soft-close mechanism 7 can pull the drawer 2 back to prevent it from flying out to the opposite side due to inertia.

[0050] In addition, since the height H1 from the worktop 13 to the bottom end of the skirting board 50 of the outer frame 5 of the double-sided drawer structure 1 is 105 mm or more, a back guard can be installed on the back of the worktop 13 and the drawer 2 can be taken out and put back in while cooking utensils such as bowls are placed on the worktop 13, so that cooking work is not hindered.

[0051] Although the double-sided drawer structure 1 according to the embodiment of the present invention has been described in detail above, the above-mentioned and illustrated embodiments are merely specific embodiments for carrying out the present invention, and therefore the technical scope of the present invention should not be interpreted as being limited by them.

[0052] In particular, as the double-sided drawer structure 1 according to an embodiment of the present invention, an example in which the double-sided drawer structure is applied to the counter kitchen 10 has been described. However, the double-sided drawer structure according to the present invention is not limited to the counter kitchen, and can be applied to a double-sided drawer structure that can be pulled out from both the front side and the back side of the storage space.
