Description

  The present invention relates to a drawer device that is manufactured at a low price with a very simple structure, and that can smoothly carry out a drawer operation, particularly in furniture such as a cabinet having a wide drawer.

Traditionally, there are cabinets that have drawers and are manufactured at low cost. In particular, as shown in FIG. 8, there are many drawers with a wide width, and those with a wide width can be stored exactly, and for example, futons can be stored easily. Furthermore, even if the price is low, many cabinets are equipped with a slide rail device for facilitating the drawer operation.
JP 10-2111045 A

  A rail member that moves relatively between the drawer and the cabinet storage chamber and a roller are provided, so that the drawer can be put in and out smoothly. The drawer guide rail is composed of parts such as a fixed rail, a slide rail, and a roller, and the slide rail is pushed out from the fixed rail to pull out the drawer from the cabinet. Further, in order to prevent the roller from being removed from the guide rail when the drawer is put in and out, the guide rail is formed with a rising piece along the longitudinal direction of the rail member as a means for preventing the roller from coming off. On the other hand, the structure is such that the roller does not fall off.

  However, when the roller detachment preventing means is formed on the rail member in this way, the number of manufacturing steps increases, and the price increases in proportion to this. Furthermore, if the roller rail prevention means is provided in both the width direction of the drawer and the guide rail device mounted on both inner wall surfaces of the drawer storage chamber, the mounting accuracy of the guide rail device between the drawer and the drawer storage chamber of the cabinet In this case, a very high one is required, and if the high mounting accuracy is not complied with, there is a possibility that the pulling in / out operation will be poor. Moreover, when assembling the drawer device with high mounting accuracy, it must be a specialized and skilled worker.

  For this reason, furniture that requires high mounting accuracy is limited to furniture such as high-grade cabinets. For furniture such as cabinets that are generally sold in large quantities at a low price, the assembly is performed by the purchaser himself. There are many sets (kits), and as described above, high-precision guide rail devices are often not used. That is, a guide rail device having a structure that is extremely simple and inexpensive is used. This simple structure and low cost guide rail device does not include the above-described means for preventing the rail member and the roller from coming off. In many cases, only the guide rail device on one side of the both sides in the width direction of the drawer is provided with means for preventing the guide rail and the roller from coming off.

  Therefore, as shown in FIG. 8, in the state where the drawer b is housed in the cabinet a, the guide rail c is in a state where the slide rail is housed in the fixed rail, and the drawer b is pulled out from the cabinet a. In some cases, the slide rail of the guide rail c protrudes smoothly from the fixed rail via a roller, and the drawer b can be stably pulled out. However, the drawer b once pulled out from the cabinet a is in a state in which the slide rail of the guide rail c is pushed out from the fixed rail, so that the slide rail is in a substantially cantilever state, and the weight of the drawer b by the slide rail. Will support the majority.

  Therefore, the weight of the drawer b is applied to the slide rail, and it becomes unstable, the sliding or rolling frictional force between the fixed rail and the slide rail increases, and the drawer b is in a state where it is difficult to move smoothly. Become. Accordingly, when the drawer b is to be stored in the cabinet a, for example, when a position separated by a distance L from the center position in the width direction of the drawer front plate is pushed, a rotational moment M is applied to the drawer b by the pushing force F, The drawer b tries to rotate on a horizontal plane (see FIG. 8). At this time, due to the rotational moment M described above, the drawer is inclined by the angle θ, and it becomes extremely difficult to store the drawer b in the cabinet a.

  In particular, when the weight of the stored item stored in the drawer b increases, the storing operation becomes more difficult. As described above, furniture such as a cabinet having a low-price drawer device has a problem in that it is difficult to perform an operation particularly when it is housed in a cabinet when the drawer has a wide width because it is inexpensive. The object (technical problem) to be solved by the present invention is to facilitate the storing operation of the drawer in the cabinet even if the furniture such as the cabinet with the drawer has a low price and simple structure. Is to be able to do.

  In view of the above, the inventor has intensively and intensively studied to solve the above-mentioned problems. As a result, the inventor of the present invention can be realized as a cabinet having a drawer storage chamber, a drawer, both inner surfaces of the drawer storage chamber, A slide guide rail mounted between the drawer, a guide member formed with a linear guide path having guide wall surfaces on both sides in the width direction, and a guided member loosely inserted into the guide path of the guide member. The guide member is mounted on either the bottom plate portion of the drawer or the floor surface portion of the drawer storage chamber, the guided member is mounted on the other side, and the guide direction of the guide member is guided in and out of the drawer. The above-described problem has been solved by employing a drawer device configured in the same direction as the direction.

  According to a second aspect of the present invention, the above-described problem is solved by adopting a drawer device in which any one pair of the slide guide rails is provided with a detachment preventing means in the above-described configuration. According to a third aspect of the present invention, the above-described problem is solved by employing a drawing device in which the guided member is formed in a cylindrical shape in the above-described configuration. According to a fourth aspect of the present invention, the above-mentioned problem is solved by employing a drawer device in which the guide member is mounted on the floor surface portion of the drawer storage chamber in the configuration described above.

  According to a fifth aspect of the present invention, in the above-described configuration, an expansion introduction portion in which a distance between the side wall surfaces gradually increases is formed at a longitudinal end portion of the guide path of the guide member, and the expansion introduction portion is drawn out and stored. The above-mentioned problem has been solved by employing a drawer device located closer to the back side of the chamber. According to a sixth aspect of the present invention, the above-described problem is solved by employing a drawer device in which the guide member is mounted on the bottom plate portion of the drawer in the above-described configuration. According to a seventh aspect of the present invention, in the above-described configuration, an expansion introduction portion in which a distance between the side wall surfaces gradually increases is formed at a longitudinal end portion of the guide path of the guide member, and the expansion introduction portion is a drawer. The above-described problem has been solved by employing a drawer device located closer to the front plate portion side.

  In the invention of claim 1, even when the guide rail device is extremely simple and inferior in accuracy, or is a drawer device manufactured at a low cost and relatively coarsely, the drawer is particularly stored. In some cases, the drawer can be housed smoothly in the cabinet without having to touch the center in the width direction of the drawer or at equal intervals.

  That is, especially in a drawer with a wide width, when storing the drawer from the drawer storage chamber of the cabinet in the drawer storage chamber of the cabinet, if you try to store it by placing it in a position away from the center position in the width direction of the drawer front, The drawer tilts on a horizontal plane and interferes with the drawer storage chamber, and is rubbed, making it difficult to pull out the drawer. Alternatively, if the guide rail for taking in and out the drawer is low in price, has poor accuracy, and is not provided with a roller derailment prevention mechanism, the guide rail rollers of the drawer and the drawer storage chamber are displaced from each other. Thus, it becomes more difficult to store the drawer.

  The present invention comprises a guide member in which a linear guide path having side wall surfaces on both sides in the width direction is formed, and a guided member loosely inserted in the guide path of the guide member, Mounted on either the lower surface of the drawer or the floor of the drawer storage chamber of the cabinet, the guided member is mounted on the other side, and the guide direction of the guide member is equal to the direction of the drawer It is configured.

  As a result, when the drawer is put in and out of the drawer storage chamber, even if a rotational moment is applied to the drawer in the process of pulling the drawer away from the center position in the width direction of the drawer front plate, With the guide member, the rotational moment can be canceled out, and the drawer retracting operation can be performed very smoothly.

  According to a second aspect of the present invention, since the guided member is formed in a cylindrical shape, the guided member can be easily inserted into the guide path of the guide member and guided along the guide path. According to a third aspect of the present invention, any one pair of the slide guide rails is provided with a detachment preventing means, that is, both slide guide rails are provided with a detachment preventing means only on one side, and the other side. Since there is no detachment prevention means, the roller and other parts can move slightly in the axial direction even if the drawer and cabinet drawer storage chamber assembly accuracy is low. Can be absorbed.

  In the invention of claim 4, the guide member is mounted on the floor surface of the drawer storage chamber, whereby the configuration of the drawer storage chamber can be simplified. According to the fifth aspect of the present invention, the guided member can be easily introduced into the guide path by the expanding and introducing portion of the guide member. In the invention of claim 6, since the guide member is mounted on the lower surface side of the drawer, the guided portion which is a small part is mounted on the drawer side, so that the structure of the drawer can be simplified. In the invention of claim 7, when the drawer is taken out from the drawer storage chamber, the guided portion can be smoothly inserted into the guide path of the guide member from the expansion introducing portion, and the drawer operation is very good. can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the present invention mainly includes a cabinet 1, a drawer 2, a slide guide rail 3, a guide member 4, and a guided member 5. In the cabinet 1, as shown in FIGS. 2A and 3B, one or a plurality of drawer storage chambers 12 are formed in the cabinet body 11. Inner side surfaces 12a, 12a are formed on both sides in the width direction of the drawer storage chamber 12, and a floor surface portion 12b is formed between the inner side surfaces 12a, 12a. When the plurality of drawer storage chambers 12, 12,... Are provided, the floor portion 12b also serves as a partition between the drawer storage chambers 12, 12 adjacent in the vertical direction [see FIG. ].

  As shown in FIGS. 1A to 1C, FIG. 2, and FIG. 3A, the drawer 2 is made up of a front plate portion 21, a back plate portion 22, side plate portions 23, 23, and a bottom plate portion 24. Composed. Then, the front plate portion 21, the back plate portion 22, and the both side plate portions 23 and 23 are arranged in opposition to each other around the floor plate portion 24 in parallel to constitute the drawer 2. A slide rail 32 of a slide guide rail 3 to be described later is attached to both side plate portions 23, 23 of the drawer 2, and a fixed rail 31 is attached to both inner side surfaces 12a, 12a of the cabinet 1. . As described above, the slide guide rail 3 is configured such that the fixed rail 31 and the slide rail 32 form a pair. The slide rail 32 protrudes along the longitudinal direction with respect to the fixed rail 31 (see FIGS. 2B and 5A). A fixed wheel 31 a is attached to the fixed rail 31. The slide rail 32 is provided with movable wheels 32a.

  The fixed wheel 31a is rotatably mounted on a vertical surface at one end in the longitudinal direction of the fixed rail 31. The movable wheel 32a is rotatably mounted on a vertical surface at one end in the longitudinal direction of the slide rail 32. Then, in a state where the fixed rail 31 and the slide rail 32 move relatively, the fixed wheel 31a relatively rotates along the slide rail 32, and similarly, the movable wheel 32a is fixed. It rotates along the rail 31.

  Two pairs of the slide guide rails 3 are provided, and are mounted between both inner side surfaces 12a, 12a of a drawer storage chamber 12 of the cabinet 1 described later and both side plate portions 23, 23 of the drawer 2. One of the two pairs of slide guide rails 3 and 3 is provided with a disengagement prevention means 33 (see FIG. 1E). The disengagement prevention means 33 prevents the fixed rail 31 and the slide rail 32 from being separated from each other when the slide operation is performed.

  More specifically, the slide wheel 32 has a substantially hanging-like detachment prevention plate piece 33a and 33b so that the fixed wheel 31a or the movable wheel 32a does not escape from the fixed rail 31 or the slide rail 32. Is formed. As a result, one of the two pairs of slide guide rails 3 and 3 has a structure that does not deviate from each other, and the other pair has a loose configuration within a range that does not deviate from each other. When the direction orthogonal to the guide direction (the direction in which the drawer 2 is put in and out) is the width direction, the fixed wheel 31a and the movable wheel 32a are within a slight range in the width direction with respect to the fixed rail 31 and the slide rail 32. It can have a movable allowable part (see FIG. 5B).

  As shown in FIGS. 1, 2, 5, and 7, the guide member 4 has a guide body 42 formed with a guide path 42 having a substantially concave cross section. The guide path 42 forms a groove-shaped passage having a substantially concave cross section, and guide wall surfaces 42a and 42a are formed on both sides in the width direction. Both guide wall surfaces 42a, 42a are formed as parallel wall surfaces at an appropriate interval. A floor surface portion 42b is formed at the lower ends of both guide wall surfaces 42a and 42a.

  The guide path 42 is formed with an expansion introduction portion 43 that gradually expands toward the outside along the longitudinal direction. The spread introduction part 43 is formed so that the distance between the guide wall surfaces 42a and 42a gradually becomes wider at the end in the guide direction (longitudinal direction) of the guide path 42 and outward. [Refer to FIG. 4 (B) to (D), FIG. 5 (A), FIG. 7)]. The spread introduction part 43 is a part for introducing and guiding the guided member 5 into the guide path 42. The guide member 4 includes a type in which the guide body 41 is composed of two members in the width direction. In this type, the two guide wall surfaces 42a, 42a are separated into two in the width direction (see FIG. 7B). In this type, the interval between the two guide wall surfaces 42a, 42a constituting the guide path 42 can be arbitrarily set.

  The guided member 5 has a guided base 52 formed on a mounting base 51. The guided member 5 is formed in a cylindrical shape, and the guided portion 52 is loosely inserted into the guide path 42. Further, the guided member 5 includes a rotating roll type in which a cylindrical portion is rotatable. Alternatively, there is a type in which a rolling sphere is mounted on the mounting base 51. The guide member 4 is mounted on the floor surface portion 12 b of the drawer storage chamber 12 of the cabinet 1, and the guided member 5 is mounted on the lower surface side of the bottom plate portion 24 of the drawer 2 through the mounting base 51. .

  The mounting position of the guide member 4 on the floor surface portion 12 b is a position near one of the inner side surfaces 12 a of the drawer storage chamber 12. That is, the drawer storage chamber 12 is mounted closer to one side in the width direction than the center position in the width direction. In particular, when either one of the slide guide rails 3 and 3 is provided with the detachment prevention means 33, the guide member 4 is provided with the slide guide rail 3 that is not provided with the detachment prevention means 33. It is mounted on the side closer to the inner surface 12a. When the guide member 4 is mounted on the floor surface portion 12 b of the drawer storage chamber 12, the expansion introduction portion 43 of the guide member 4 is installed so as to be located on the back side of the drawer storage chamber 12. The guide member 4 is fixed to the floor surface portion 12b of the drawer storage chamber 12 via a fixing tool such as a screw. Alternatively, the guide member 4 may be fixed by an adhesive.

  The guided member 5 is attached to the lower surface of the bottom plate portion 24 of the drawer 2 so as to properly enter the guide path 42 of the guide member 4 when the drawer 2 is taken in and out of the drawer storage chamber 12. Specifically, it is fixed on the lower surface side of the bottom plate portion 24 of the drawer 2 at a position near the back plate portion 22. As such a configuration, when the drawer 2 is stored in the drawer storage chamber 12 of the cabinet 1, the guided member 5 is detached from the guide path 42 of the guide member 4.

  When the drawer 2 is pulled out from the drawer storage chamber 12, the guided member 5 is introduced from the expansion introduction portion 43 of the guide path 42 of the guide member 4, and the guided member 5 is guided to the guide path 42. The drawer 2 is pulled out from the drawer storage chamber 12 while being guided by the The guide member 4 may be mounted on the lower surface side of the bottom plate portion 24 of the drawer 2, and the guided member 5 may be mounted on the floor surface portion 12 b of the drawer storage chamber 12. Also in this case, the guide member 4 is not at the center in the width direction of the front plate portion 21 of the drawer 2 but at the end portion, that is, at the position near one of the side plate portions 23 of the drawer 2. . The guided member 5 is also mounted so as to properly enter the guide path 42 of the guide member 4 and to be guided.

  In the present invention, the guide member 4 is attached to the floor portion 12 b of the drawer storage chamber 12 of the cabinet 1. A guided member 5 is mounted on the lower surface side of the bottom plate portion 24 of the drawer 2. The guide member 4 is formed with linear guide paths 42 having side wall surfaces 42a, 42a on both sides in the width direction, and the guide direction of the guide path 42 of the guide member 4 is equal to the direction of exit / out of the drawer 2 [Refer to FIG. 1 (A), (B), FIG. 4, FIG. 5 (A), (B), etc.)]. The drawer 2 is stored in the drawer storage chamber 12 so that the guided portion 52 of the guided member 5 is loosely inserted into the guide path 42.

  In the state where the drawer 2 is completely stored in the drawer storage chamber 12, the guided member 5 is configured to be disengaged from the guide path 42 of the guide member 4 (see FIGS. 1A and 1B). That is, when the drawer 2 is pulled out from the drawer storage chamber 12 of the cabinet 1, the guided member 5 is not in the guide path 42 a of the guide member 4 in the initial state. Then, in the process of pulling out the drawer 2 from the drawer storage chamber 12, the guided member 5 is introduced from the expansion introduction portion 43 of the guide member 4 at a substantially initial stage, and the drawer 2 is guided by the guide member 4 and the guided member 5. It can be pulled out in a stable state along the direction of taking in and out of the drawer storage chamber 12.

  Further, when the drawer 2 is stored in the drawer storage chamber 12 again from the state in which the drawer 2 is most pulled out from the drawer storage chamber 12 within the pull-out range of the slide guide rail 3, the following process is performed. That is, when the drawer 2 is pushed by placing the hand in the center position in the width direction of the front plate portion 21 of the drawer 2 and stored, the drawer 2 may be moved and stored as it is. However, in the case where it is not possible to put a hand on the center in the width direction of the front plate portion 21, that is, in the case where a hand is placed at a position away from the center position in the width direction of the front plate portion 21 of the drawer 2 by a distance L, In the process of storing the drawer 2 in the drawer storage chamber 12, normally, the drawer 2 is subjected to a rotational moment Ma (see FIGS. 2B, 4A, and 5A). ].

  As shown in FIGS. 2 (B), 4 (A), and 5 (A), this rotational moment Ma becomes a force that attempts to rotate the drawer 2 clockwise on a horizontal plane. In this state, in both the slide guide rails 3 and 3, the fixed rail 31 and the slide rail 32 of each slide guide rail 3 are pressed against each other, and the sliding property of the slide rail 32 with respect to the fixed rail 31 becomes poor. As a result, the storage operation of the drawer 2 may be defective.

  Therefore, when the rotational moment Ma is applied to the drawer 2, the guided member 5 comes into contact with one guide wall surface 42a with a pressing force in the guide path 42 of the guide member 4, and as a result, the guide A reaction force T is generated on the wall surface 42a [see FIGS. 4, 5A, 5C]. The reaction force T moves together with the guided member 5 moving along the guide path 42 [see FIGS. 4C and 4D]. That is, the action of rotating by the rotational moment Ma is canceled by the reaction force T generated by the guide member 4 and the guided member 5 (see FIGS. 4, 5A and 5C), and the drawer 2 Moves in a substantially appropriate state along the taking-in / out direction without tilting on the horizontal plane, and the drawer 2 is stored in the drawer storage chamber 12.

  Therefore, the drawer 2 can be stored very smoothly. Further, in the embodiment in which the slide guide rails 3 and 3 are provided with the disengagement prevention means 33 only on one side of the pair, and the other pair is not provided with the disengagement prevention means 33, the drawer 2, even if the assembly accuracy of the drawer storage chamber 12 of the cabinet 1 and the slide guide rail 3 is low, the slide guide rail 3 not provided with the disengagement prevention means 33 is used in the width direction (the approach of the slide rail 32). Can be moved in the direction perpendicular to the take-out direction), and errors in the mounting accuracy of the slide guide rail 3 can be absorbed (see the arrow in the width direction in FIG. 5B). Is something that can be done.
