Description

  The present invention relates to a drawer-type storage device that is preferably used in an office or the like.

In this type of drawer-type storage device, as shown in, for example, Patent Document 1 and the like, a drawer rail and an inner wall rail are formed on a side surface of the drawer and an inner wall that supports the drawer, respectively, and the drawer is connected to the inner wall via these rails. In general, it is slidably supported.

By the way, since the conventional thing makes a drawer rail and an inner wall rail contact directly like the said patent document 1, if it uses repeatedly, a rail will be shaved by friction and it will become easy to produce a catch at the time of drawer insertion / extraction operation. There is a problem.

In order to eliminate such problems, recently, a sliding member is provided on the upper surface of the front end portion of the inner wall rail, and a sliding member is provided on the lower surface of the rear end portion of the drawer, and the drawer is provided via these sliding members. It is also conceivable to support the inner wall to reduce the friction when the drawer is put in and out.
JP 2002-65380 A

However, there is a clearance in the width direction between the drawer and the inner wall, which is necessary when the drawer is put in and out of the inner wall, including the drawer rail and the inner wall rail. Then, the drawer can finely move in the width direction while swinging its butt within the clearance range. For this reason, the drawer that should be straight out along the rail may be pulled in and out in a tilted direction, which causes the drawer and part of the drawer rail to be strongly pressed against the corresponding inner wall rail or inner wall, etc. A high frictional force may be generated in the part, and a situation where it cannot be inserted or removed may occur. Therefore, it is difficult to appropriately improve the usability of this type of drawer-type storage device only by improving the sliding property in the vertical direction.

An object of the present invention is to provide a drawer-type storage device that effectively solves such problems.

In order to achieve this object, the present invention takes the following measures.

That is, in the drawer-type storage device of the present invention, the drawer rail and the inner wall rail are respectively formed on the side surface of the drawer and the inner wall that supports the drawer, and the drawer is slidably supported on the inner wall via both the rails. An inner wall-side flat sliding member that is preferentially attached to the lower surface of the drawer rail over the inner wall rail is provided near the front end of the inner wall rail, and on the inner wall rail near the rear end of the drawer rail. When a drawer-side planar sliding member preferentially attached to the inner wall is provided and the drawer is supported on the inner wall at four points from below via both planar sliding members, and when the drawer approaches the inner wall near the front end of the inner wall rail Is provided with an inner wall-side vertical sliding member that can be attached to the tip of the drawer rail or the side of the drawer in preference to the inner wall rail. When the drawer approaches the inner wall, a drawer side vertical sliding member that can be attached to the tip of the inner wall rail or the inner wall is given priority over the drawer rail, and the width direction between the drawer and the inner wall is achieved by these compatible surface sliding members. It is characterized in that the direct contact of can be avoided at the four side points of the drawer.

In this way, the drawer rail and the inner wall rail are not in direct contact with each other in the vertical direction, and are supported at four points via the plane sliding member. It is possible to achieve smooth withdrawals. Moreover, even if the drawer is inclined at the time of the drawer, the drawer and the inner wall are not in direct contact with each other in the width direction, and are supported at four points on the side of the drawer via the vertical sliding member. It is also possible to effectively avoid a situation in which a high frictional force is generated in the meantime and the state cannot be removed or inserted. Moreover, even if a material having high sliding property is used for the entire inner wall and drawer, even if it becomes expensive, according to the present invention, it can be handled by using only a small sliding member. Since it does not depend on the material of the drawer itself, it is possible to ensure the freedom of material selection for the drawer and the inner wall without impairing the ease of taking in and out.

In order to increase the production efficiency, the inner wall side sliding member is used as an inner wall side flat sliding member and the inner wall side vertical sliding member, and the drawer side sliding is used as a drawer side flat sliding member and a drawer side vertical sliding member. It is desirable to use a member.

Specifically, the inner wall rail is integrally molded with resin on the inner wall, the drawer rail is integrally molded with resin on the drawer, the sliding member attached to the inner wall side, and the sliding member attached to the drawer side are each integrally molded with resin, and each sliding member These resin materials are selected so that the coefficient of friction with the attachment destination is smaller than the coefficient of friction between the members in direct contact without these sliding members.

Because of this rail support structure, the drawer can be reliably supported without hanging forward at the drawer end, but as a structure for that purpose, there is a sliding member attached to the drawer side when the drawer is pulled out. When making contact with the sliding member attached to the door to prevent the drawer from coming off, a protrusion that contacts or is close to the lower surface of the inner wall rail at the time of the contact is projected outward on the side surface at the rear end of the drawer. It is preferable to provide it.

Rail support structure that can easily accommodate storage devices with different heights without significant cost increase. Inverted side plate members arranged on the inner wall across multiple stages and shared with left and right side plates. The top plate, the bottom plate, and the back plate are fitted to these side plates so that they cannot be separated to form a housing, and rails provided on the inner walls of the left and right side plates that are positioned on the same step when inverted. It is set in advance so that they are mirror-symmetric with each other, the drawer is supported between the left and right rails, and the sliding member attached to the inner wall side is reversed so that it can be attached to the inner wall or inner wall rail of the left and right side plates. It is desirable.

In particular, the rail has a vertically asymmetrical shape, and the side plate member has a vertically symmetric structure with respect to the center in the height direction, and the rail that is used and the rail that is not used when arranged as the left and right side plates Are positioned alternately in the vertical direction, and when the role of the rail that is used and the rail that is not used is interchanged between one side plate and the other side plate, the inner wall side is between the used rail and the unused rail. By inserting the sliding member attached to the stool, the installation convenience can be effectively improved.

  In particular, when the used rails and the unused rails are connected by ribs, the sliding members are pressed into the used rails, the unused rails, and the portions surrounded by the ribs to thereby press the sliding members. The wearing state can be improved.

  For the same purpose, it is desirable that the sliding member attached to the drawer side is reversed left and right and can be attached to the left and right drawer rails or the side surfaces thereof.

  Since the present invention is configured as described above, it is possible to provide a drawer-type storage device that supports the drawer smoothly from the vertical direction and the left-right direction, and has excellent usability with a long-term smooth pull-in / out characteristic. It becomes.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The drawer storage device of this embodiment is an assembly type as shown in FIGS. 1 and 2, and a left plate 1 and a left plate 3 mainly composed of a side plate member 10 made of a hard resin material, a top plate 2 made of a resin material, and a bottom plate 3. And the back plate 4 are assembled to each other to form the housing A, and the drawer 5 is supported in the storage space S formed in the housing A via the inner wall rails 11 and 12 provided on the left and right side plates 1.

The side plate 1 and the back plate 4, and the top plate 2 and the back plate 4 are assembled so that they cannot be separated by engaging the engaging portions 4y. Although not shown, the relationship between the bottom plate 3 and the back plate 4 is the same. Inability to separate means that it is difficult to separate unless special tools are used. Such a structure is, for example, engaged if one of the engaging part or the engaged part of the pair is elastically deformed and restored at a deep position of engagement and is not elastically deformed again using a tool. Can be easily realized by an appropriate configuration that cannot be released.

Next, paying attention to the left side plate 1 when viewed from the front, as shown in FIGS. 2 and 7A, the inner wall rail 11 stands upward toward the front end side thereof, and then curves in a partial arc shape toward the front from there. The inner wall rail 12 has a bulging portion 12a that hangs downward on the front end side thereof and curves forward from there, and these are alternately arranged in the height direction. is doing. When the left side plate 1 is turned upside down and used as the right side plate 1, as shown in FIG. 2, the inner wall rail 12 of the right side plate 1 is attached to the corresponding portion of the inner wall rail 11 of the side plate 1 located on the left side. The inner wall rail 11 of the right side plate 1 faces the corresponding portion of the inner wall rail 12 of the side plate 1 located on the left side at the same height, and the left and right inner wall rails 11, 12 and the inner wall rails 12, 11 are mirror surfaces. It is configured to be symmetric. At this time, as shown in FIG. 9, the left inner wall rail 12 and the right inner wall rail 11 become “used rails” that actually support the drawer 5, and the left inner wall rail 11 and the right inner wall rail 12 are “used”. Rails that are not. "

In this embodiment, the front and rear ends of the rail 11 (12) that is used and the rail 12 (11) that is not used are connected by the ribs 15a and 15b as shown in FIGS. Of these, the rib 15b is used as a part of the fitting structure of the casing A. Specifically, protrusions 15c are provided rearwardly in the vicinity of the upper end and the vicinity of the lower end of the rear surface of the rib 15b at the rear end, and a boss hole 45c provided at a corresponding position of the back plate 4 is engaged with the protrusion 15c. I try to let them. Similarly to these, the top plate 2 and the bottom plate 3 are provided with projections 25 c and 35 c, and a boss hole 45 c is provided in a corresponding portion of the back plate 4.

On the other hand, as shown in FIGS. 1 and 2, the drawer 5 is mainly composed of a flat box-shaped drawer body 5a made of a hard resin material in which the left and right side plates 51 are connected by a bottom plate 52, a mirror plate 53, and a rear plate 54. Therefore, a protrusion rail 51a having a protrusion extending in the front-rear direction is provided on the outer surface of the side plate 51 of the drawer body 5a, and a handle 55 is provided in front of the end plate 53. As shown in FIG. 9, the outer surface of the side plate 51 of the drawer body 5a is disposed so as not to interfere with the inner wall rails 11 and 12 formed on the inner walls of the left and right side plates 1, and projects outward from the side surface of the drawer body 5a. The drawer rails 51a are attached and supported on the corresponding inner wall rail 12 of the left side plate 1 and the inner wall rail 11 of the right side plate 1. As shown in FIG. 2 and FIG. 14, below the vicinity of the rear end of the drawer rail 51 a of the drawer 5 is the rear of the bulging portion 12 a (11 a) of the inner wall rail 12 (11) when the drawer 5 is pulled out. A protrusion 51b is provided to contact the opposite surface and prevent it from coming off. In the drawer 5, the lower surface on the front end side of the drawer rail 51a is supported by the upper surface of the bulging portion 12a (11a) of the inner wall rails 12 and 11, and the rear end side is flat on the inner wall rail 12 (11) through the lower surface of the protrusion 51b. Supported on the upper surface of the part. When the drawer 5 is pulled out, the drawer rail 51a and the protrusion 51b are lifted up so that they do not pass through the gap between the inner wall rail 12 (11) and the inner wall rail 11 (12) positioned on the upper side thereof. It has a structure that does not come off. Further, the drawer 5 is provided with a projection 51c further below and below the projection 51b. The projection 51c is brought into contact with the lower surface of the inner wall rail 12 (11) when the drawer 5 is pulled out to the maximum. It plays the role which prevents 2 sagging. The protrusion 51b is inserted into and removed from a portion (reference numeral 15ax in FIG. 14) where the protruding amount of the rib 15a connecting the front end portions of the inner wall rails 11 and 12 is small.

Here, what slightly improved the said drawer | drawing-out support structure is shown in FIGS. In these drawings, ribs not shown in FIGS. 1 to 15 are also shown.

In this drawer support structure, an inner wall side sliding member 91 is provided in the vicinity of the front ends of the inner wall rails 11 and 12, and a drawer side sliding member 92 is provided in the vicinity of the rear end of the drawer rail 51a, and the drawers are pulled out through these sliding members 91 and 92. 5 is supported on the inner wall of the side plate 1.

The inner wall side sliding member 91 is formed by resin-integrated molding and is provided with a channel-shaped main body 91a and a projecting piece 92 projecting sideways from the bottom of the main body 91 as shown in FIG. Between the rail 11 (12) and the unused rail 12 (11). The main body 91 and the projecting piece 92 are also tightly press-fitted between the front and rear ribs 10x and 10y provided at a portion connecting the used rail 11 (12) and the unused rail 12 (11). . As described above, the side plate member 10 of the present embodiment is inverted upside down and shared by the left and right side plates 1 as described above, but the inner wall side sliding member 91 also has a vertically symmetric shape. It can be mounted on one inner wall. When the drawer rail 51a is inserted into the groove of the channel-shaped main body 91a in the mounted state, the upward inner wall side plane sliding portion 91x set in the groove is used as shown in FIGS. The lower surface of the drawer rail 51a is given priority over the inner wall rails 11 and 12 and is located at a position protruding upward from the upper surface of the rail 11 (12) to be applied (the same applies to the bulging portions 11a and 12a). It is set so as to be attached to the inner wall side plane sliding portion 91x. Further, when the drawer 5 approaches the inner wall of the side plate 1, the inner wall side set at the front end of the inner wall side sliding member 91 has priority over the front ends 11 b, 12 b of the inner wall rails 11, 12 being attached to the side surface 5 b of the drawer 5. The vertical sliding portion 91y1 is attached to the side surface 5b of the drawer 5, or the inner wall side vertical sliding portion 91y2 set in the groove of the inner wall side sliding member 91 is set to be attached to the tip 51d of the drawer rail 51a. is doing.

On the other hand, as shown in FIG. 16, the drawer-side sliding member 92 is formed of a substantially L-shaped resin, and an engaging portion 92a is attached to a notch 51e provided near the rear end of the drawer rail 51a. A drawer-side planar sliding portion 92x connected to the lower side of 92a is attached to the lower surface of the drawer rail 51a, and a drawer-side vertical sliding portion 92y connected in the orthogonal direction from the base end of the drawer-side planar sliding portion 92x. Is attached to the side surface 5b. The notch 51e and the engaging portion 92a have a dovetail structure, and can only be removed from the horizontal direction. The protrusion 51e1 and the hole 92a1 that are fitted to each other at that time are provided in the notch 51e and the engaging portion 92a, respectively. Provided. Further, an engaging piece 51f having a downwardly hooked shape protrudes from the side surface 5b below the drawer rail 51a, and a window 92b provided at the center of the drawer side vertical surface sliding portion 92y is elastic to the engaging piece 51f. By engaging, the drawer-side sliding member 92 is attached to the drawer 5. This drawer-side sliding member 92 has a symmetrical shape in the front-rear direction, and can be mounted on a part of the drawer 5 extending from the left and right drawer rails 51a to the side surface 5b. When the drawer rail 51a is inserted between the rail 11 (12) to be used and the rail 12 (11) not to be used in the mounted state, as shown in FIGS. The lower surface of the drawer is located below the lower surface of the drawer rail 51a, and the drawer side plane sliding portion 92x is set on the inner wall rails 11 and 12 with priority over the drawer rail 51a. Yes. Further, when the drawer 5 approaches the inner wall of the side plate 1, the drawer side vertical surface sliding portion 92 y has priority over the inner wall rail 11, rather than the tips 11 b and 12 b of the inner wall rails 11 and 12 being attached to the side surface 5 b of the drawer 5. It is set so as to be attached to the 12 tips 11b and 12b.

In other words, as shown in FIG. 19, this drawer support structure supports the load of the drawer 5 at four points from below through both plane sliding portions 91x and 92x, and also draws out 5 through the compatible surface sliding portions 91y and 92y. Can be supported at four points on the side.

The sliding members 91 and 92 are made of a resin material different from the drawer 5 as the attachment destination and the inner wall of the side plate 1, and the friction coefficient between the sliding members 91 and 92 and the attachment destination is More than the friction coefficient between the members that would be in direct contact without these sliding members 91 and 92 (that is, between the inner wall of the side plate 1 or the inner wall rails 11 and 12 and the drawer rail 51a or the side surface 5b of the drawer 5). It is set to be a small value. As a specific example, the drawer 5 and the inner wall of the side plate 1 may be formed of a polystyrene material together with the drawer rail 51a and the inner wall rails 11 and 12, and the sliding members 91 and 92 may be formed of a polyacetal material. The coefficient of friction due to the contact between polyacetal and polystyrene is relatively low compared to the coefficient of friction due to direct contact between polystyrene.

Further, when the drawer 5 is pulled out from the position of FIG. 17, the drawer side sliding member 92 attached to the drawer 5 side is brought into contact with the inner wall side sliding member 91 attached to the inner wall side as shown by the arrow in FIG. It has a structure that can prevent the pull-out, and when pulling out the drawer 5, the drawer 5 is lifted to use the drawer rail 51a and the drawer-side plane sliding portion 92x and the rail 12 (11) used on the upper stage side. The structure is such that it cannot pass through the channel groove of the inner wall side sliding member 91 unless it passes through the gap with the rail 11 (12) that is not. Then, when the sliding members 91 and 92 are in contact with each other, a protrusion 151 c that contacts or is close to the lower surface of the inner rail 11 (12) protrudes outward on the side surface 5 b at the rear end of the drawer 5. This projection 151c serves to prevent the drooping of the drawer 5 in the same manner as the projection 51c of FIG. Such a front-sag prevention effect is possible because the drawer-side sliding member 92 is provided slightly forward from the rear end of the drawer 5 and can be formed a projection 151c at the rear end of the drawer 5 with a predetermined distance therebetween. It is what. This protrusion 151c is also inserted / removed from the portion 15ax having a small protrusion amount of the rib 15a connecting the front end portions of the inner wall rails 11 and 12.

Hereinafter, additional structures other than the drawer support structure will be described. 1 to 15, this assembling type storage device plastically deforms the thin plate material shown in FIG. 2 at each edge of the top plate 3 and the left and right side plates 2 that are positioned at the opening edge of the casing A.

A drawer-side planar sliding portion 92x that is preferentially attached to the inner wall rails 11 and 12 over the rail 51a is provided, and the drawer 5 is supported on the inner wall at four points from below via both the planar sliding portions 91x and 92x. In addition, when the drawer 5 approaches the inner wall in the vicinity of the front end of the inner wall rails 11 and 12, the drawer 5 is attached to the tip 51d of the drawer rail 51a or the side surface 5b of the drawer 5 in preference to the inner wall rails 11 and 12. Provided inner wall side vertical sliding portions 91y2 and 91y1 are provided, and when the drawer 5 approaches the inner wall in the vicinity of the rear end of the drawer rail 51a, the drawer rail 51a In addition, a drawer-side vertical sliding member 92y that can be attached to the tips 11b and 12b of the inner wall rails 11 and 12 is provided with priority, and the width-direction direct contact between the drawer 5 and the inner wall by these compatible surface sliding members 92x and 92y. Can be avoided at the four points on the side of the drawer 5.

In this way, the drawer rail 51a and the inner wall rails 11 and 12 are not in direct contact with each other in the vertical direction, and are supported at four points via the plane sliding portions 91x and 92x, thus eliminating problems such as scraping of the rails. Thus, it is possible to realize a smooth operation of the drawer 5. In addition, even if the drawer 5 is inclined at the time of the drawer, the inner wall and the drawer rail 51a or the inner wall rails 11 and 12 and the side surface 5b of the drawer 5 are not in direct contact with each other, and the drawer 5 is drawn through the vertical sliding portions 91y and 92b. Therefore, it is possible to effectively avoid a situation in which a high frictional force is generated between the drawer 5 and the rails 11 and 12 and cannot be inserted and removed. Moreover, even if it is expensive to use a highly slidable material for the inner wall of the side plate 1 or the entire drawer 5, according to the present invention, it can be dealt with only by using the small sliding members 91 and 92. Since it is inexpensive and does not depend on the inner wall of the side plate 1 or the material of the drawer 5 itself, it is possible to ensure the flexibility of selecting the material of the drawer 5 and the side plate 1 without impairing the ease of taking in and out.

In particular, the inner wall side sliding member 91 is used as an integral part of the inner wall side flat sliding portion 91x and the inner wall side vertical sliding portion 91y, and also serves as the drawer side flat sliding portion 92x and the drawer side vertical sliding portions 92y1 and 92y2. Since the drawer side sliding member 92 is used as a thing, the number of parts and an assembly man-hour can be reduced effectively.

Specifically, the inner wall rails 11 and 12 are integrally molded with resin on the inner wall of the side plate 1, the drawer rail 51 a is integrally molded with resin on the drawer 5, and the sliding portions 91 x and 91 y attached to the inner wall side of the side plate 1 are on the drawer 5 side. The sliding portions 92x and 92y to be attached to the resin are integrally molded with resin, and the coefficient of friction between the sliding members 91 and 92 is determined by the friction between the members in direct contact without the sliding members 91 and 92. Since the resin material is selected from the viewpoint of making the value smaller than the coefficient, the effect of the present invention can be surely obtained, and the selection criteria are clarified.

Because of such a rail support structure, the drawer 5 can be reliably supported without being drooped forward at the drawer end. However, as a structure for that purpose, the sliding member 91 attached to the drawer 5 side when pulled out is provided on the inner wall. When the drawer 5 is made to come into contact with the sliding member 92 attached to the side to prevent the drawer 5 from coming off, a protrusion 151c that comes into contact with or closes to the lower surface of the inner wall rails 11 and 12 is brought into contact with the side surface at the rear end of the drawer 5 Since the drawer 5 is provided so as to protrude outward, it is possible to effectively eliminate problems such as the drawer 5 being difficult to use, or the drawer 5 being in an incomplete support state and being deformed.

Further, in this embodiment, the side plate member 10 in which the rails 11 and 12 are arranged on the inner wall over a plurality of stages is inverted and shared with the left and right side plates 1, and the top plate 2, the bottom plate 3, and the back plate 4 are used as these side plates 1. Are fitted together so that they cannot be separated, and the rails 11, 12 (12, 11) provided on the inner walls of the left and right side plates 1 that are positioned in the same step when reversed are formed. Is set in advance so as to have mirror symmetry, and the drawer is supported between the left and right rails 11 and 12, and the sliding member 91 attached to the inner wall side is also reversed and attached to the left and right side plates 1. It is possible.

In this way, when obtaining an assembly-type effect, the side plate 1 and the sliding member 91 are shared on the left and right sides, so that the number of parts can be reduced as much as possible and cost reduction can be pursued as much as possible. As an effect of the assembly type, it is possible to easily cope with the difference in the number of stages of the storage device as shown in FIG. 15 only by changing the height of the side plate 1 and the back plate 4. Also, the resin molding die itself is flat and inexpensive, and the convenience of handling is improved because each component does not take up space before assembly.

In this storage device, the rails 11 and 12 have a vertically asymmetric shape, and the side plate member 10 has a vertically symmetric structure with respect to the center in the height direction, and is arranged as the left and right side plates 1. In this case, the rails 11 (12) used and the rails 12 (11) not used are alternately positioned in the vertical direction, and the rails 11 (12) used in this way on one side plate 1 and the other side plate 1 are used. The roles of the rails 12 (11) that are not used are interchanged. Even when the rails 11 and 12 themselves are vertically asymmetrical, when the rails 11 and 12 are reversed and used on the left and right side plates 1, the rails 11 and 12 are paired. Thus, the mirror 11 is mirror-symmetrical, so that it is possible to form an appropriate drawer support structure by performing required shaping on the rails 11 and 12 without impairing the common convenience. And since the sliding member 91 attached to the inner wall side can be press-fitted between the rail 11 (12) used and the rail 12 (11) not used, the installation convenience can be improved effectively. Note that the vertical asymmetry mentioned here means that when the rail 11 is viewed, for example, there is an upward bulging portion 11a at the front end portion, and when inverted upside down, this becomes a downward bulging portion and does not have the same shape before and after inversion. It is asymmetrical up and down. The same applies to the rail 12.

In particular, in this embodiment, the used rail 11 (12) and the unused rail 12 (11) are connected by ribs 10x and 10y. However, the used rail 11 (12) and the unused rail 12 are used. By fitting the sliding member 91 into the part surrounded by (11) and the ribs 10x and 10y, the mounting state of the sliding member can be improved.

For the same purpose, the sliding member 92 attached to the drawer 5 side can be reversed and attached to the part extending from the left and right drawer rails 51a to the side surface 5b. .

In addition, it does not prevent comprising a plane sliding part and an elevation surface sliding part using a separate member. Further, the drawer side vertical surface sliding portion may be provided in a direction in which the protruding amount of the drawer rail 51a is increased and preferentially attached to the inner wall of the side plate 1. Further, when the drawer-side sliding member 92 is attached, as shown in FIG. 20, the boss portion 5z is integrally projected from the side surface 5b of the drawer 5, and the boss portion 5z is engaged with a hole 92z provided in the drawer-side sliding member 92. You may make it match.
