Description

  The present invention relates to a storage device such as a storage case or a chest for storing clothes, for example.

  Conventionally, for example, a storage device (hereinafter, a conventional example) disclosed in Japanese Patent No. 4170257 has been proposed as a storage device in which a drawer body is provided so as to be freely inserted and removed from a frame body.

  This conventional example has a frame body having a space portion surrounded by a frame made of synthetic resin, and a drawer body that is assembled and housed in a space portion of the frame body so that it can be pulled out and stored in the space portion of the frame body. The rail is arranged along the moving direction of the drawer, while the drawer is provided with a roller that can roll within the rail.

  Therefore, the conventional example is a problem that occurs when the sliding portion between the frame body and the drawer body that has been proposed so far is made of synthetic resin, that is, when the drawer body is inserted into and removed from the frame body. Since they slide while being in surface contact with each other, the problem that the sliding resistance is large and the sliding operability of the drawer is poor can be solved.

Japanese Patent No. 4170257

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  When the drawer body 2 is taken in and out of the frame body 1, the rolling part 4 </ b> A provided on the left and right side surface portions 2 a at the rear end portion of the drawer body 2 moves in the insertion and withdrawal direction. Rolls on the provided driven part 3A. On the other hand, the driven part 3B provided on the left and right side surface parts 2a of the drawer 2 moves in the direction of taking in and out, and is provided on the left and right side parts 1a as the front end of the frame body 1 as the driven part 3B moves. The rolling part 4B rolls on the driven part 3B.

  The drawer body 2 is supported by the rolling portions 4A and 4B at the front, rear, left and right positions of the drawer body 2, so that the drawer body 2 is inserted into and removed from the frame body 1. Each rolling part 4A, 4B is performed by rolling the driven parts 3A, 3B, and smooth insertion / extraction is performed as compared with the insertion / extraction performed by simply sliding between members.

  Further, in the present invention, the above-described rolling part 3B on which the rolling part 4B of the frame 1 rolls is provided on the left and right side surface parts 2a of the drawer body 2, while the rolling part 4A of the drawer body 2 is provided. Rolling driven parts 3A are provided on the left and right side surface parts 1a of the frame body 1, and the respective driven parts 3A and 3B are integrally formed on the left and right side surface parts 1a and 2a of the frame body 1 and the drawer body 2, respectively. Is done.

  Therefore, unlike the conventional example described above, for example, a troublesome assembling process that requires assembling accuracy, which is indispensable by separately providing a metal rail, is not necessary, and the mass productivity is very good. Since the moving parts 3A and 3B are obtained by integral molding that is easy to obtain accuracy, the structure that realizes the smooth insertion and withdrawal of the drawer 2 described above can be obtained simply and reliably.

  Further, in the present invention, a protrusion 3A having a length in the direction in which the drawer body 2 is taken in and out is integrally formed on the left and right side surface portions 1a of the frame body 1 so that the protrusion 3A serves as the driven part 3A. A protrusion 3B having a length in the sliding direction of the drawer 2 is integrally formed on the left and right side surfaces 2a of the two, and this protrusion 3B is used as a driven part 3B. Each of the driven parts 3A and 3B is a drawer. 2 is formed by continuous protrusions 3A and 3B having a length in the sliding direction, so that the accuracy required for the rolling part 4A and 4B to be rolled is easily obtained in this point as well. A structure capable of realizing smooth insertion / removal can be obtained easily and reliably, and each of the driven parts 3A and 3B functions as a reinforcing structure that reinforces the frame 1 and the drawer 2 and is extremely efficient. It has a good structure, and each of the driven parts 3A, 3B is a frame 1 Because so that minimal material simply by integrally molding a portion of the fine drawer body 2 respectively, it is less costly in this regard.

  Further, according to the present invention, when the drawer body 2 is taken in and out of the frame body 1, the drawer body 2 is always supported by the rolling portions 4A and 4B positioned in the front, rear, left and right directions. Since this loading / unloading is performed by the rolling of the portions 4A and 4B, extremely stable and smooth loading / unloading is achieved.

  That is, if the frame body 1 is not provided with a rolling part, and only the drawer body 2 is provided with four rolling parts at the front, rear, left and right positions of the drawer body 2, the drawer body 2 is pulled out due to its structure. The rolling parts on the left and right sides of the front side fall off from the driven part provided in the frame body 1 and the pulling amount of the drawer body 2 is very small if an attempt is made to avoid the falling part of the rolling part. It becomes inconvenient. This also causes the same problem when all four rolling portions are provided on the frame 1, and in any case is insufficient as a drawer structure for the drawer 2. In order to cope with this problem, it is conceivable to increase the number of rolling parts, but it is not practical because the cost is high and the mass productivity is low.

  In this regard, in the present invention, the rolling portions 4A and 4B are arranged at optimal positions so that the above-described problems do not occur. Specifically, the rolling portion 4B of the frame body 1 is arranged at the front end of the frame body 1. The rolling part 4A of the drawer body 2 is provided at the left and right side surface part 1a as the rear end of the drawer body 2 and is always provided regardless of the drawer state of the drawer body 2. The drawer body 2 is supported by the front and rear, left and right rolling parts 4A and 4B, so that the drawer body 2 can always be stably and smoothly pulled out, and this structure is possible. In addition, it has excellent effects such as fewer parts and can be manufactured at low cost.

  Further, for example, the rolling part 3A of the frame body 1 has a pair of protrusions 3A arranged at positions opposed to each other through a gap through which the rolling part 4A of the drawer body 2 can pass. When it is formed integrally with the part 1a, the reinforcement structure is even better, and it is always pulled out at any position in the range from the state where the drawer 2 is fully pulled out to the state where the drawer 2 is stored. A state in which the rolling part 4A of the body 2 rolls the rolled part 3A of the frame body 1 is obtained, and in this respect also, the drawer body 2 can be smoothly put in and out.

  Specifically, due to the structure described above, for example, when the drawer body 2 is pulled out to the maximum with respect to the frame body 1, the drawer body 2 is, for example, due to its own weight or the weight by storing the object to be stored therein. When the drawer body 2 is put in and out with the drawer body 2 tilted forward, the rear body 2 is tilted forward. When the rolling part 4 </ b> A provided at the end rolls the upper protrusion 3 </ b> A related to the rolled part 3 </ b> A of the frame body 1, and the drawer body 2 is stored to a certain position with respect to the frame body 1. The drawer 2 is in a horizontal state from the above-described tilted state, but when the drawer 2 is put in and out in the horizontal state, the rolling part 4A of the drawer 2 is a frame. The lower protrusion 3 </ b> A related to the rolled part 3 </ b> A of the body 1 rolls.

  Accordingly, by configuring the driven part 3A, on which the rolling part 4A of the drawer body 2 rolls, with a pair of protrusions 3A arranged in the vertically opposed positions, which position is the drawer position of the drawer body 2 Regardless of this, a state in which the rolling part 4A of the drawer body 2 always rolls the rolled part 3A of the frame 1 is obtained.

  In addition, for example, at least one of the protrusions 3A constituting the rolled portion 3A of the frame 1 is a pair of plate-like ribs 3a facing each other with a gap between them, and a construction rib constructed between the plate-like ribs 3a In the case of a reinforcing rib structure composed of 3a ', or, for example, the protrusion 3B constituting the rolled part 3B of the drawer 2 has a pair of plate-like ribs 3b facing each other via a gap and the plate-like ribs In the case of a reinforcing rib structure composed of an erected rib 3b ′ laid between 3b, a more excellent function as a reinforcing structure for reinforcing the frame body 1 or the drawer body 2 will be exhibited.

  Further, for example, the left and right side surfaces 1a and 2a of the frame body 1 and the drawer body 2 are made of synthetic resin, and when the driven portions 3A and 3B are integrally formed on the left and right side surfaces 1a and 2a, By adopting integral molding of a synthetic resin that has a degree of freedom in shape that can be molded and is easy to obtain accuracy, a structure that exhibits the above-described effects can be obtained easily and reliably.

  In addition, for example, at the rear end portion of the rolled portion 3A of the frame body 1, there is provided a falling inclined portion 8A that is concaver than other portions and the rolling portion 4A of the drawer body 2 falls and rolls, and the drawer body 2 At the front end of the rolled part 3B, there is provided a sloping inclined part 8B that is concave from the other parts and the rolling part 4B of the frame body 1 falls and rolls, and the sloping sloping parts 8A and 8B are respectively connected to the frame 1 When the drawer body 2 is configured to be in a storage state for holding the storage state of the drawer body 2 stored in the frame body 1, when the drawer body 2 is in the storage state with respect to the frame body 1, the pulling body 2 is forced to move backward. Therefore, unless the drawer body 2 is consciously pulled out, it is possible to prevent the drawer body 2 from moving forward as much as possible. In addition, the drawer body 2 in the pulled out state is collected. When trying to do so, the drawer body 2 is naturally stowed from a position before the position where the drawer body 2 is completely stowed, so that it is very easy to use and has a high-class feeling. In addition, since the sloping inclined portions 8A and 8B provided at the driven portions 3A and 3B are provided at the front and rear positions, the drawer body 2 in the retracted state with respect to the frame body 1 is horizontal and has a good appearance. In this respect, the product value is high.

  Further, for example, the rolling parts 4A and 4B of the drawer body 2 or the frame body 1 are configured so as to be rotatable on the mounting member 5 attached to the drawer body 2 or the frame body 1, and the mounting member 5 is a drawer body. 2 or the first component 5A disposed on the side surfaces 2a and 1a of the frame 1 and the side surfaces 2a and 1a and the corner R of the drawer 2 or frame 1 connected to the first component 5A. For example, when the rolling parts 4A and 4B roll on the driven parts 3A and 3B, the rolling parts 4A and 4B roll on the rolling parts 3A and 3B. The load applied to the moving parts 4A and 4B is distributed to a plurality of surface parts (side surface part, continuous surface part continuous through the side surface part and the corner part) via the mounting member 5 described above. Therefore, the mounting member 5 is not enlarged by avoiding partial concentration of the load. Also be provided with a sufficient mounting strength.

  From this, it is possible to easily and surely obtain a structure for realizing the smooth insertion / extraction of the drawer body 2 with respect to the frame body 1 and to be excellent in mass productivity, and to manufacture at a low cost. .

  That is, for the attachment part of the rolling portions 4A and 4B provided on the drawer body 2 or the frame body 1, sufficient strength can be obtained by, for example, a synthetic resin integral when the drawer body 2 or the frame body 1 is molded of synthetic resin. For this reason, the rolling parts 4A and 4B are attached via, for example, a metal attachment member 5, but in this case (the metal 1 is attached to the synthetic resin attached part of the frame 1 or the drawer 2). In the case where the mounting member 5 is provided), if the metal mounting member 5 is made large in order to obtain sufficient connection strength to avoid partial concentration of the load, the cost increases accordingly. In the conventional example, the entire rail is made of metal, and a part of the metal rail is used as a roller mounting portion, which is expensive.

  In this regard, as described above, when the rolling portions 4A and 4B roll on the driven portions 3A and 3B, the load applied to the rolling portions 4A and 4B is reduced to a part of the drawer body 2 or the frame body 1 ( The first component 5A and the second component 5B constituting the mounting member 5 are not structured to be received in a concentrated manner on one surface portion), and the side surfaces 2a and 1a of the drawer body 2 or the frame body 1 and the side surfaces 2a, 1a and the continuous surface portions 2b, 1b that are continuous through the corner portion R, and the structure that can cope with the above-mentioned load distributed over a plurality of surface portions, that is, the first component portion that constitutes the mounting member 5 5A and the second component 5B are arranged on a plurality of surface portions of the drawer body 2 or the frame body 1 and are arranged on the corner portion R having the strength of the drawer body 2 or the frame body 1, Sufficient connection strength can be obtained without increasing the size of the attachment member 5.

  Accordingly, the mounting member 5 that is separate from the frame body 1 or the drawer body 2 can be made small from the above-described configuration, so that the mounting member 5 can be manufactured at a low cost even if it is made of metal, for example.

  Further, for example, the first component portion 5A provided on the side surface portions 2a and 1a of the drawer body 2 or the frame body 1 and provided with the shaft portion 6 that pivotally supports the rolling portions 4A and 4B, and the continuous surface portions 2b and 1b In the case where the mounting member 5 is configured by connecting the second component 5B provided with the fastening portion 7 that is disposed and fastened to the continuous surface portions 2b and 1b in an L shape, the mounting member 5 is configured. Since it is L-shaped, a good and firm mounting state matched with the side surface portions 2a, 1a and the continuous surface portions 2b, 1b via the corner portion R can be obtained, and the first component 5A and the first Each of the two component parts 5B is provided with various structures and has an efficient structure. Further, the fastening part 7 is provided on the second component part 5B on which the rolling parts 4A and 4B are not provided. The fastening portion 7 is located at a position retracted from the driven portions 3A and 3B where the moving portions 4A and 4B roll. Since become bets, the fastening part 7 is structured not any hindrance to the rolling of the rolling unit 4A, 4B.

  Further, for example, the attachment member 5 is formed by bending a metal plate material into an L-shaped plate, and a portion on one side of the bent portion 5C of the attachment member 5 is a first component portion 5A, and the like. In the case where the side portion is the second component 5B, the mounting member 5 has a simple structure, so the cost is reduced and the mass productivity is excellent.

  In addition, for example, the drawer body 2 or the frame body 1 is configured to include a bottom surface portion and side surface portions 2a and 1a standing on the left and right positions of the bottom surface portion, and the drawer body 2 or the side surface portion 2a of the frame body 1 When the continuous surface portions 2b and 1b continuing through the corner portion R are the bottom surface portion, the continuous surface portions 2b and 1b are, for example, the front body portion or the back surface portion of the drawer body 2 or the frame body 1. In comparison, the load in the vertical direction applied to the mounting member 5 can be more reliably received by the side surface portions 2a and 1a and the bottom surface portion that are in the vertical relationship with each other.

  Further, for example, when the frame 1 or the drawer body 2 has at least the side surface portions 1a and 2a and the continuous surface portions 1b and 2b made of synthetic resin and the mounting member 5 is made of metal, the manufacturing surface, cost, and strength are increased. It becomes a very efficient structure in which materials are selected according to the purpose of each part such as a surface.

  A specific embodiment of the present invention will be described with reference to the drawings.

  The present embodiment is a storage device in which a drawer body 2 is provided in a manner that allows the drawer body 2 to be inserted into and removed from the frame body 1.

  In the present embodiment, a storage case for storing clothes is employed as the storage device. However, any structure that exhibits the characteristics of the present embodiment, such as a drawer or desk drawer structure, may be used as appropriate. .

  Hereinafter, each component according to the present embodiment will be described in detail.

  As shown in FIGS. 1 and 2, the frame body 1 is integrally formed with an appropriate synthetic resin member, and is erected at a bottom surface portion 1 b having a square shape in plan view and at the left and right positions of the bottom surface portion 1 b. It has a side surface portion 1a and a back surface portion 1c erected at the back surface position of the bottom surface portion 1b, and is configured to be connected to a plurality of (two) stacks in the vertical direction with the other frame body 1. That is, the frame 1 is surrounded by each frame component (bottom surface portion 1b, left and right side surface portions 1a and back surface portion 1c) made of synthetic resin and a top plate 9 (or a bottom surface portion 1b of another frame body 1) described later. The drawer body 2 is assembled and housed in the space portion of the frame body 1 so as to be freely drawn out. In addition, the frame 1 may be configured such that, for example, the frame components are separated from each other, only the left and right side surfaces 1a are made of synthetic resin, and the others are made of metal. In addition, each frame body configuration portion is not limited to a plate shape as long as it has a structure that forms a surface such as a frame shape or a net shape (mesh shape) with an open center. Reference numeral 13 denotes a leg that is detachably provided on the bottom of each frame 1.

  A top plate 9 is installed on the upper portion of the uppermost frame 1.

  The top plate 9 is a rectangular plate-like body formed of an appropriate wooden member as shown in FIGS. 1 and 7, and a plurality of (four in total) recesses 9a are formed at the front, rear, left and right positions of the lower surface. . The top plate 9 may be made of a synthetic resin, but wooden is effective in terms of design, for example, when giving a high-class feeling.

  The concave portion 9a is a portion for connecting the upper end portion 1a 'of the side surface portion 1a of the frame body 1. In this embodiment, the upper end portion 1a' of the side surface portion 1a of the frame body 1 is inserted into the concave portion 9a. Instead of being directly connected, they are connected via a connecting body 10.

  The connecting body 10 is a thin plate-like long body formed of an appropriate metal member as shown in FIG. 7, and the front and rear ends of the connecting body 10 are arranged on the front and rear sides of the top plate 9 ( Alternatively, a pair of connecting projections 10a are provided to be inserted into the respective left and right recesses 9a. On the other hand, on the back side of the front and rear end portions of the connecting body 10 and on the back side of the connecting projection 10a, the side surface portion 1a of the frame 1 is provided. The connection recessed part 10b which fits into upper end part 1a 'of this is provided. The connecting body 10 is not limited to metal but may be made of, for example, plastic (reinforced plastic), and the connecting protrusions 10a are inserted into the left and right recesses 9a of the top board 9 so as to be disposed on the top board 9. It may be configured.

  When the top plate 9 is actually connected to the side surface portion 1a of the frame body 1 via the connecting body 10, the connecting convex portions 10a of the connecting body 10 are inserted into the front and rear concave portions 9a in advance and stopped. The connecting body 10 is fixed to the top plate 9 using the screw 11, and in this state, the connecting recess 10 b of the connecting body 10 is fitted and connected to the upper end portion 1 a ′ of the side surface portion 1 a of the frame body 1. In addition, between the recessed part 9a of the top plate 9 and the connection convex part 10a of the connection body 10, and between the connection recessed part 10b of the connection body 10 and the upper end part 1a 'of the side part 1a of the frame 1, it is appropriate. There is provided a retaining stopper. Further, in this embodiment, the connecting body 10 is fixed to the top plate 9 by passing the fixing screw 11 through the central portion of the connecting body 10, but it is fixed to the connecting convex portion 10a (the connecting concave portion 10b). The connecting body 10 may be fixed to the top plate 9 by passing through the screw 11 and screwed into the concave portion 9a of the top plate 9. In this case, the fixing screw 11 is not exposed after assembly and the appearance is changed. very good.

  By the way, by adopting a structure in which the top plate 9 and the frame body 1 are connected via the connecting body 10, the mass productivity and cost efficiency of the storage device are drastically improved.

  Specifically, when the top plate 9 is made of wood as described above, each recess 9a formed on the lower surface of the top plate 9 is formed by cutting, but the positional relationship between the recesses 9a and each recess Advanced technology is required to form the size and shape of 9a with high accuracy. That is, if the upper end portion 1a ′ of the side surface portion 1a of the frame body 1 is inserted and directly connected to the concave portion 9a in a state of low accuracy, the assembly is not good (it is loose even if assembled) or cannot be assembled. Such problems will occur. Synthetic resin molded products are easy to obtain accuracy, but wooden cutting is extremely difficult to obtain.

  Therefore, in this embodiment, by adopting the connection structure via the connection body 10 described above, even if the formation accuracy of the concave portion 9a of the top plate 9 is slightly low, the metal (or reinforced plastic) formed in advance with high accuracy is used. Therefore, the top plate 9 and the upper end portion 1a ′ of the side surface portion 1a of the frame body 1 can be reliably connected with each other. As a result, accuracy is not required, so that mass production is excellent, yield is good, and cost is low.

  Further, the thickness of the connecting body 10 is appropriately adjusted, for example, between the lower edge of the side surface of the top plate 9 and the upper edge of the side surface portion 2a of the drawer body 2 described later (or the side surface portion 1a of the upper frame body 1). A function as a cosmetic body that conceals a gap generated between the lower edge of the drawer body 2 and the upper edge of the side surface portion 2a of the drawer body 2 housed in the lower frame body 1 can also be exhibited.

  The frame body 1 is configured so that a drawer body 2 to be described later can be inserted and housed from the front opening, and a rolling part 4A of the drawer body 2 to be described later rolls on the left and right side surface portions 1a. A rolling part 3A is provided.

  As shown in FIG. 2, each of the driven parts 3A is integrally formed in a projecting form in the lower part of the left and right inner side surface parts 1a of the frame body 1 and is arranged so as to be opposed to each other with a gap therebetween.
