Description

[Technical Field]

[0001] The present invention relates to a drawer structure and a fixture. [Background technology]

[0002] In the past, fixtures with drawer structures have often been used in work spaces such as offices, public facilities, schools, and homes to store items that workers use in their work. The drawer structure is such that the drawer body can slide back and forth along rails that extend in the front-to-rear direction and are attached to the side panels of the fixture.

[0003] Also known is a suspension rail equipped with multiple rail members to ensure sufficient drawer extension. For example, the suspension rail of the drawer structure disclosed in Patent Document 1 below includes an outer rail attached to the side panel of the fixture, an inner rail attached to the drawer body, an intermediate rail provided between the outer rail and the inner rail, and rolling balls that roll in rolling grooves formed in the outer rail, inner rail, and intermediate rail. The rolling balls roll along the rolling grooves, allowing the drawer body to slide. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 2715878 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the drawer structure described in Patent Document 1, the rolling balls roll in the rolling grooves formed in each rail, so if there is variation in the left-right mounting position of the drawer body, the relative positions of the rails will also be shifted left-right. As a result, the rolling balls will no longer roll smoothly in the appropriate positions within the rolling grooves, which will put a load on each rail, causing damage to the rails and reducing the operability of the drawer body.

[0006] Therefore, the present invention has been made in consideration of the above circumstances, and provides a drawer structure and fixture that provide good operability in pulling out the drawer body. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention employs the following means. That is, the drawer structure according to the present invention comprises a drawer main body having an article storage section formed therein, a first rail attached to a first mounting surface of a fixture main body, a second rail attached to a second mounting surface of the drawer main body that faces the first mounting surface in the left-right direction, and a support rail interposed between the first rail and the second rail and having rolling balls that roll to allow the second rail to slide in the front-rear direction relative to the first rail, and an adjustment mechanism provided at least one between the second mounting surface and the support rail and between the support rail and the first mounting surface, and capable of adjusting the left-right distance between the first mounting surface and the second mounting surface, Second mounting surfacethe first bracket attached to the second rail, a second bracket attached to the second rail, and a connecting portion that connects the first bracket and the second bracket so that the position in the left-right direction can be changed, the connecting portion having a long hole that is long in the left-right direction and formed in one of the first bracket or the second bracket, a screw hole formed in the other of the first bracket or the second bracket, and a screw that is inserted into the long hole and screwed into the screw hole, the long hole being formed in a first plate portion of the first bracket, and the screw hole being formed in a second plate portion of the second bracket, the first plate portion being arranged above the second plate portion with the long hole and the screw hole overlapping when viewed from the top-bottom direction.

[0008] In a drawer structure configured in this manner, even if the distance between the first mounting surface of the fixture body and the second mounting surface of the drawer body becomes longer or shorter than the design value due to factors such as the accuracy of the mounting of the fixture body, the adjustment mechanism adjusts the left-right distance between the first mounting surface and the second mounting surface. Generally, if either the first rail or the second rail is misaligned left or right, the rolling balls will not roll smoothly, resulting in poor rail operability. In the above drawer structure, the adjustment mechanism adjusts the left-right distance between the first mounting surface and the second mounting surface, preventing loads caused by left-right misalignment from acting on the support rail, thereby reducing damage to the support rail and improving operability when pulling out the drawer body. Furthermore, since the adjustment mechanism adjusts the left-right distance between the first mounting surface and the second mounting surface, the support rail itself does not need to have the function to adjust its position left-right, and a general-purpose support rail can be used. Furthermore, the first bracket and the second bracket are connected by the connecting portion so that their positions in the left-right direction can be changed, which makes it easy to adjust the left-right positions of the first bracket and the second bracket, improving the workability during adjustment. Furthermore, the left-right position can be adjusted by inserting a screw into the elongated hole in either the first bracket or the second bracket and threading it into the screw hole in the other of the first bracket and second bracket. Therefore, the left-right position can be easily adjusted depending on the position of the screw inserted into the elongated hole, making adjustment work easier. Furthermore, the first plate portion of the first bracket in which the elongated hole is formed is disposed above the second plate portion of the second bracket in which the screw hole is formed, so that the screw fastening work can be performed from above the first bracket and the second bracket, reducing the burden of the work during adjustment.

[0015] In addition, in the drawer structure according to the present invention, a drawer body having an article storage section formed therein; a first rail attached to a first mounting surface of the fixture body; a second rail attached to a second mounting surface of the drawer body that faces the first mounting surface in the left-right direction; a support rail interposed between the first rail and the second rail and having rolling balls that roll to allow the second rail to slide in the front-rear direction relative to the first rail; and an adjustment mechanism provided at least one between the second mounting surface and the support rail and between the support rail and the first mounting surface, which is capable of adjusting the left-right distance between the first mounting surface and the second mounting surface; The drawer body may include a bottom plate and a front plate extending upward from a front portion of the bottom plate, and the front plate may be positioned in front of and overlapping the adjustment mechanism.

[0016] In a drawer structure configured in this way, the front panel of the drawer body is positioned in front of and overlaps the adjustment mechanism, so when viewed from the front, the adjustment mechanism is hidden by the front panel of the drawer body and cannot be seen, resulting in a good appearance.

[0017] In addition, the fixture according to the present invention is a drawer structure comprising: a drawer main body having an article storage section formed therein; a first rail attached to a first mounting surface of the fixture main body; a second rail attached to a second mounting surface of the drawer main body that faces the first mounting surface in the left-right direction; a support rail interposed between the first rail and the second rail and having rolling balls that roll to allow the second rail to slide in the front-rear direction relative to the first rail; and an adjustment mechanism provided at least one between the second mounting surface and the support rail and between the support rail and the first mounting surface, which is capable of adjusting the left-right distance between the first mounting surface and the second mounting surface; A fixture body having a plurality of support legs installed on the floor; The fixture body includes a rail support member provided between support legs spaced apart in the front-rear direction, and the surface of the rail support member facing the second mounting surface in the left-right direction constitutes the first mounting surface. .

[0018] In fixtures configured in this manner, even if the distance between the first mounting surface of the fixture body and the second mounting surface of the drawer body becomes longer or shorter than the design value due to factors such as the accuracy of the mounting of the fixture body, the adjustment mechanism adjusts the left-right distance between the first mounting surface and the second mounting surface. Generally, if either the first rail or the second rail is misaligned left or right, the rolling balls will not roll smoothly, resulting in poor rail operability. In the above-mentioned drawer structure, the adjustment mechanism adjusts the left-right distance between the first mounting surface and the second mounting surface, preventing loads caused by left-right misalignment from acting on the support rail, thereby reducing damage to the support rail and improving operability when pulling out the drawer body. The support rail is attached to the first mounting surface of the rail support member provided between the front and rear support legs of the fixture body. Therefore, the drawer structure can be installed by simply providing the rail support member to the fixture body, and the drawer body can be installed on existing or general-purpose fixture bodies by adjusting the left-right mounting position. [Effects of the Invention]

[0021] According to the drawer structure and fixture of the present invention, the drawer body can be easily pulled out. [Brief explanation of the drawings]

Before the screw 431 is screwed into the screw hole 423b of the second bracket 42, the first bracket 41 and the second bracket 42 are able to move relative to each other in the width direction Dw. In this state, the screw 431 is moved in the width direction Dw to adjust the distance in the width direction Dw between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer main body 20, thereby adjusting the mounting position of the drawer main body 20 in the width direction Dw on the fixture main body 1. By tightening the screw 431 into the screw hole 423b, the first bracket 41 and the second bracket 42 are connected, and the mounting position of the drawer main body 20 in the width direction Dw on the fixture main body 1 is determined.

[0061] Figure 3 shows a case where the distance between the left and right rail support members 17 is secured as per the design drawing. Figure 6 shows a case where the distance between the left and right rail support members 17 is short after the rail support members 17 have been installed. In this case, the distance in the width direction Dw between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer main body 20 is adjusted to be short. The screw 431 is positioned in the elongated hole 413a closer to the drawer main body 20 (inside in the width direction Dw) and is screwed into the screw hole 423b. In this case, the gap s1 between the end 24a of the front panel 24 and the support leg 11 is narrow.

[0062] 7 shows a case where the distance between the left and right rail support members 17 is long after the rail support members 17 are installed. In this case, the distance in the width direction Dw between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer body 20 is adjusted to be long. The screw 431 is positioned in the elongated hole 413a closer to the support rail 30 (outside in the width direction Dw) and is screwed into the screw hole 423b. In this case, the gap s1 between the end 24a of the front plate 24 and the support leg 11 is widened.

[0063] As shown in FIG. 4, the front panel 24 of the drawer body 20 is disposed in front of and overlaps with the support rail 30, the adjustment mechanism 40 and a portion of the rail support member 17.

[0064] In the shelf 100 configured in this manner, even if the distance between the mounting surface 192a of the fixture main body 1 and the mounting surface 23a of the drawer main body 20 becomes longer or shorter than the design value due to factors such as the mounting accuracy of the fixture main body 1, the adjustment mechanism 40 adjusts the mounting position of the drawer main body 20 in the width direction (left and right direction) Dw. Generally, when either the outer rail 31 or the inner rail 32 shifts in the width direction Dw, the rolling ball 341 shifts from the rolling grooves 312c and 332c, and the rolling ball 351 shifts from the rolling grooves 322d and 332d, pressure is applied to the rolling balls 341 and 351, preventing smooth rolling and reducing operability of the rails. In the drawer structure 2 of this embodiment, the adjustment mechanism 40 adjusts the mounting position of the drawer main body 20 in the width direction Dw, and loads caused by misalignment in the width direction Dw do not act on the support rail 30, thereby suppressing damage to the support rail 30 and improving operability when pulling out the drawer main body 20.

[0065] Furthermore, since the adjustment mechanism 40 adjusts the mounting position of the drawer body 20 in the width direction Dw, the support rail 30 itself does not need to have the function to adjust the position in the width direction Dw, and a general-purpose support rail 30 can be used.

[0066] Furthermore, the first bracket 41 and the second bracket 42 are connected by the connecting portion 43 so that their positions in the width direction Dw can be changed. This makes it easy to adjust the positions of the first bracket 41 and the second bracket 42 in the width direction Dw, improving the workability during adjustment.

[0067] Furthermore, the position in the width direction Dw is adjusted by inserting the screw 431 into the elongated hole 413a of the first bracket 41 and screwing it into the screw hole 423b of the second bracket 42. Therefore, the position in the width direction Dw can be easily adjusted by the position of the screw 431 inserted into the elongated hole 413a, making it possible to further improve the workability during adjustment.

[0068] Additionally, the upper bent plate portion 413 of the first bracket 41, in which the elongated hole 413a is formed, is disposed above the upper bent plate portion 423 of the second bracket 42, in which the screw hole 423b is formed. Therefore, the screw fastening work can be performed from above the first bracket 41 and the second bracket 42, reducing the workload during adjustment.

[0069] The first bracket 41 and the second bracket 42 are made of a metal material, and therefore have high strength, so that when the drawer main body 20 is pulled out, the first bracket 41 and the second bracket 42 are deformed, which prevents misalignment and breakage in the width direction Dw.

[0070] Additionally, the front panel 24 of the drawer body 20 is positioned to overlap the front of the support rail 30, the adjustment mechanism 40, and part of the rail support member 17. Therefore, when viewed from the front, the support rail 30, the adjustment mechanism 40, and part of the rail support member 17 are hidden by the front panel 24 of the drawer body 20 and cannot be seen, thereby improving the appearance.

[0071] Additionally, the support rail 30 is attached to the mounting surface 192a of the rail support member 17 provided between the front and rear support legs 11 of the fixture main body 1. Therefore, the drawer structure 2 can be installed by providing the rail support member 17 on the fixture main body 1, and therefore the drawer main body 20 can be installed on an existing or general-purpose fixture main body 1 by adjusting the mounting position in the width direction Dw.

[0072] (Variation) Next, fixtures according to a modified example of one embodiment of the present invention will be described mainly with reference to Figure 8. In the modified examples described below, components corresponding to the embodiment shown above may be assigned the same reference numerals and descriptions thereof may be omitted. As shown in FIG. 8, an adjustment mechanism 40A according to this modification includes a first bracket 41, a second bracket 42A, and a connecting portion 43A.

[0073] The second bracket 42A has an attachment plate portion 425, a lower bent plate portion 426, a first bent plate portion 427, a second bent plate portion 428, and an upper bent plate portion (second plate portion) 429.

[0074] The mounting plate portion 425 is formed in a plate shape. The plate surface of the mounting plate portion 425 faces the width direction Dw. The mounting plate portion 425 is disposed on the inside in the width direction Dw of the inner base plate 321 of the inner rail 32 of the support rail 30. A screw 321a is inserted through a mounting hole 425a of the mounting plate portion 425 and is threadedly engaged with a weld nut 425b provided on the mounting plate portion 425.

[0075] The lower bent plate portion 426 extends inward in the width direction Dw from the lower end of the mounting plate portion 425. The lower bent plate portion 426 is formed in a plate shape. The plate surface of the lower bent plate portion 426 faces the up-down direction Dv. The lower bent plate portion 426 is disposed below the lower bent plate portion 412 of the first bracket 41. The lower bent plate portion 426 has a notch 426a formed in a position where the screw 412b is disposed.

[0076] The first bent plate portion 427 extends outward in the width direction Dw from the upper end of the mounting plate portion 425. The first bent plate portion 427 is formed in a plate shape. The plate surface of the first bent plate portion 427 faces in the up-down direction Dv.

[0077] The second bent plate portion 428 extends upward from the outer end portion in the width direction Dw of the first bent plate portion 427. The second bent plate portion 428 is formed in a plate shape. The plate surface of the second bent plate portion 428 faces the width direction Dw.

[0078] The upper bent plate portion 429 extends inward in the width direction Dw from the upper end of the second bent plate portion 428. The upper bent plate portion 429 is formed in a plate shape. The plate surface of the upper bent plate portion 429 faces the up-down direction Dv. The upper bent plate portion 429 is disposed below the upper bent plate portion 413 of the first bracket 41.

[0079] A plurality of screw holes 429b are formed at intervals in the front-rear direction Da in the upper bent plate portion 429. When viewed from the up-down direction Dv, the screw holes 429b are positioned so as to overlap with the elongated holes 413a formed in the upper bent plate portion 413 of the first bracket 41.

[0080] The first bent plate portion 427, the second bent plate portion 428 and the upper bent plate portion 429 are arranged above the support rail 30 and between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer main body 20.

[0081] The connecting portion 43A has an elongated hole 413a formed in the upper bent plate portion 413 of the first bracket 41, a screw hole 429b formed in the upper bent plate portion 429 of the second bracket 42A, and a screw 431. The screw 431 is inserted into the elongated hole 413a from above the upper bent plate portion 413 of the first bracket 41 and is screwed into the screw hole 429b of the upper bent plate portion 429 of the second bracket 42A. Before the screw 431 is screwed into the screw hole 429b of the second bracket 42A, the first bracket 41 and the second bracket 42A can move relative to each other in the width direction Dw.

[0082] In shelf 100 configured in this manner, even if the distance between mounting surface 192a of fixture main body 1 and mounting surface 23a of drawer main body 20 becomes longer or shorter than the design value due to factors such as the mounting accuracy of fixture main body 1, adjustment mechanism 40A adjusts the mounting position of drawer main body 20 in the width direction Dw. Generally, when either outer rail 31 or inner rail 32 shifts in the width direction Dw, rolling ball 341 shifts from rolling grooves 312c, 332c, and rolling ball 351 shifts from rolling grooves 322d, 332d, pressure is applied to rolling balls 341, 351, preventing smooth rolling and reducing operability of the rails. In the drawer structure 2 of this embodiment, the adjustment mechanism 40A adjusts the mounting position of the drawer main body 20 in the width direction Dw, and loads caused by misalignment in the width direction Dw do not act on the support rail 30, thereby suppressing damage to the support rail 30 and improving operability when pulling out the drawer main body 20.

[0083] Furthermore, since the adjustment mechanism 40A adjusts the mounting position of the drawer body 20 in the width direction Dw, the support rail 30 itself does not need to have the function of adjusting the mounting position in the width direction Dw, and a general-purpose support rail 30 can be used.

[0084] Additionally, the first folded plate portion 427, the second folded plate portion 428, the upper folded plate portion 429 and the connecting portion 43A are disposed above the support rail 30 and between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer main body 20. This makes it possible to shorten the distance between the mounting surface 192a of the rail support member 17 and the mounting surface 23a of the drawer main body 20, thereby ensuring a large distance in the width direction Dw of the drawer main body 20.

[0085] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0086] For example, in the embodiment shown above, the drawer structure 2 is installed on a shelf 100 having a plurality of shelves 16, but the present invention is not limited to this. The drawer structure may also be installed on furniture such as a wagon or desk on which a plurality of drawer bodies 20 are arranged, and the type of furniture can be set as appropriate.

[0087] In the embodiment described above, the rail support member 17 has the mounting portion 18 and the support portion 19, but the present invention is not limited to this. The rail support member can be configured appropriately as long as it is provided between the front and rear support legs 11 and has the mounting surface 192a to which the support rail 30 is attached.

[0088] Furthermore, in the embodiment described above, one drawer body 20 is installed in the width direction Dw of the shelf 100, but the present invention is not limited to this. Multiple drawer bodies 20 may be arranged adjacent to each other in the width direction Dw. In this case, a partition plate may be provided between adjacent drawer bodies 20 so as to stand upright from the shelf board 16, and a support rail 30 may be attached to the partition plate.

[0089] Furthermore, in the embodiment described above, the adjustment mechanism 40 is provided between the drawer main body 20 and the support rail 30, but the present invention is not limited to this. The adjustment mechanism 40 may be provided between the support rail 30 and the mounting surface 192a of the rail support member 17. A configuration may also be adopted in which the inner rail 32 of the support rail 30 is attached to the drawer main body 20, the adjustment mechanism 40 is attached to the rail support member 17, and the outer rail 31 of the support rail 30 is attached to the adjustment mechanism 40.

[0090] In the embodiment described above, the first bracket 41 has the elongated hole 413a formed therein, and the second bracket 42 has the screw hole 423b formed therein into which the screw 431 is screwed, but the present invention is not limited to this. The elongated hole may be formed in the second bracket, and the first bracket may have the screw hole formed therein into which the screw is screwed.

[0091] In the above embodiment, the support rail 30 includes three rail members: the outer rail 31, the inner rail 32, and the intermediate rail 33. However, the present invention is not limited to this. The support rail may include at least two rail members. For example, the support rail may include the outer rail 31, the inner rail 32, and rolling balls that can roll in the rolling grooves formed in the outer rail 31 and that are engaged with the inner rail 32.
