  The present invention relates to a door mechanism for opening and closing front surfaces of storage shelves, display shelves, and the like, and more particularly, to a detachable flip-up storage door mechanism that can store a door plate inside a shelf.

  2. Description of the Related Art Conventionally, shelves used for storing or displaying books, documents, miscellaneous goods, etc. in homes and offices and the like are provided with a flip-up door that can be stored. As such a flip-up type storage door mechanism, for example, a door plate provided with a pair of rollers on the left and right upper ends, and a U-shaped rail mounted on the left and right sides of the upper shelf plate with the openings inside. It is known that the roller can run on the lower side of the rail. In such a flip-up type storage door mechanism, the door is opened by holding the handle provided on the front surface of the door plate and rotating the door plate upward, and further, the door plate is lifted to a horizontal state. The door plate can be slid and housed inside the shelf by pushing backward.

  However, in a shelf equipped with a flip-up type storage door as described above, when the door plate is slid in and out of the shelf, the door plate tends to rattle from side to side, and the center of the handle is held straight. There was a problem that the door could not be moved in and out smoothly unless force was applied.

  Conventionally, in order to prevent the door plate from swinging back and forth due to vibration or the like when the door is closed, a magnet is provided inside the shelf, and the magnetic metal piece attached to the door plate or the door plate. The thing which made it possible to lock a door board by adsorb | sucking is known. However, in such a case, there is a problem that the magnet becomes an obstacle when putting in and out an object from the shelf, and the usability is deteriorated.

  The present invention has been made to solve such a problem, and the object of the present invention is to be a detachable type that can be opened and closed smoothly and easily without rattling when sliding the door. Providing a flip-up storage door mechanism and a detachable flip-up storage door mechanism capable of preventing the door plate from swinging in a closed state without providing a locking means such as a magnet inside the shelf. That is.

  The detachable flip-up storage door mechanism according to the present invention, which has been made to solve the above problems, has a front surface of a space between two upper and lower shelf boards suspended between two side panels arranged in parallel. In the detachable flip-up storage door mechanism that opens and closes, a) has at least a hanging side and a bottom extending substantially perpendicularly from the lower edge, and the extending direction of the bottom on each side of the lower surface of the upper shelf board. A pair of rails that are detachably attached to the inside; b) a long-hole-shaped guide slit provided on the hanging side of the rail; and c) a groove on the peripheral surface, and the periphery of the guide slit by the groove. A door plate provided with a pair of rollers on both sides of the upper end, which are engaged with a portion and run in the guide slit, d) a lateral blur preventing member provided on the inner surface of the front end portion of the hanging side of each rail, and e ) A door plate support member provided on the top surface of the bottom front end of each rail It is characterized by having.

  In the present invention, unless otherwise specified, the top and bottom, front and rear, and left and right are defined based on the case where the door mechanism is attached to the shelf and the door is viewed from the front with the door closed.

  It is desirable that the detachable flip-up storage door mechanism further has a handle at the lower front portion of the door plate that comes into contact with the front surface of the lower shelf when the door is closed.

  Further, the detachable flip-up storage door mechanism according to the present invention further includes a roller mounting portion that is formed by providing a notch at the upper edge of the rear end of the guide slit, and is capable of entering and exiting the roller. It is desirable to have a roller detachment preventing member made of an detachable elastic body at the rear end.

  Moreover, the detachable flip-up storage door mechanism according to the present invention is configured such that the front end of the guide slit is inclined slightly downward and a notched roller receiving portion is provided at the lower edge of the rear end of the guide slit. You can also.

  A shelf according to another aspect of the present invention is a shelf provided with the detachable flip-up storage door mechanism as described above, and has a plurality of spaces surrounded by two side plates and two upper and lower shelf plates. The detachable flip-up storage door mechanism is provided in at least two or more of the plurality of spaces, and the color of at least one of the door plates is different from the color of the other door plates. It is characterized by.

  The material of the detachable flip-up storage door mechanism of the present invention and the shelf to which the door mechanism is attached is typically steel, but is not particularly limited and may be a metal such as aluminum or duralumin. In addition to the materials, non-metallic materials such as plastics can also be used. Therefore, for example, the door plate can be constituted by a combination of an acrylic plate and a steel frame.

  According to the removable flip-up storage door mechanism of the present invention configured as described above, the movement of the roller is restricted by engaging the groove of the roller and the peripheral edge of the guide slit, and is provided at the front end of the rail. The lateral blur prevention member blocks the gap formed between the inner side surface of the rail and the side surface of the door plate, and restricts the left and right movement of the door plate. Therefore, when the door plate is taken in and out of the shelf, it can be smoothly pulled out without rattling regardless of the portion of the handle. Further, when the door plate is slid, a door plate support member is provided at a position on the rail that comes into contact with the lower surface of the door plate (the rear surface when the door is closed). The sliding can be improved and the door can be slid more smoothly. The door plate support member also has a function of preventing the door plate from coming into contact with the bottom side, the upper side, etc. of the rail when the door plate is slid (details will be described later).

  In addition, when a handle is provided at the lower front of the door plate that contacts the front surface of the lower shelf when the door is closed, the handle acts as a stopper when the door plate is substantially vertical when the door is closed. The rotation of the door can be stopped. Furthermore, when the door is closed, a moment in the rear direction (inner side of the shelf) acts on the door plate due to the weight of the handle, etc., and the handle is biased to the front surface of the lower shelf plate. It is possible to prevent the door plate from swinging back and forth due to vibration or the like.

  Further, as described above, in the case where the roller mounting portion provided at the rear end of the guide slit and the roller detachment preventing member that can be attached to and detached from the rear end of the guide slit are provided, the guide slit extends from the roller mounting portion. After the roller is inserted into the guide slit, a roller detachment prevention member made of an elastic material such as rubber is attached to the rear end of the guide slit, so that the roller attached to the guide slit can be prevented from coming off during use and the door plate can be stored. Sometimes the impact and sound caused by the roller and the rear end of the guide slit abutting can be reduced.

  In addition, when the front end of the guide slit is inclined downward, the roller position is stabilized when the door is pulled out, so that the rotation operation can be performed smoothly. In addition, when a notch-shaped roller receiving portion is provided at the lower edge of the rear end of the guide slit, when the door plate is stored inside the shelf, the roller falls into the roller receiving portion and is locked, Inadvertent closing of the door can be prevented.

  According to the shelf according to another aspect of the present invention, in the shelf having a plurality of spaces surrounded by the two side plates and the upper and lower two shelf plates, the door plates are color-coded according to the usage of each space. Even if the door is closed, it is possible to grasp at a glance what kind of objects are stored in each space.

FIG. 2 shows an enlarged front view of a roller peripheral portion in a state where the detachable flip-up storage door mechanism of this embodiment is attached to the shelf board. The detachable flip-up storage door mechanism of the present embodiment is composed of a pair of rails 10 attached to the left and right lower surfaces of the upper shelf plate 24a and a door plate 12 having a pair of rollers 13 at the upper end. The roller 13 can travel along the rail 10 by engaging the guide slit 11 on the long hole provided in the groove 13 and the groove 13 a provided on the peripheral surface of the roller 13.

  The door plate 12 has substantially the same width W as the shelf plates 24a and 24b, and the length L is made substantially equal to the distance between the lower surface of the upper shelf plate 24a and the upper surface of the lower shelf plate 24b. However, it is desirable that the length of the door plate 12 be equal to or less than the depth D of the shelf plates 24a and 24b. A pair of rollers 13 having grooves 13a on the peripheral surface is rotatably attached to both side surfaces of the upper end of the door plate 12, and a handle 14 formed by bending a metal wire or the like is provided on the front surface of the lower end. As shown in FIG. 1 (b), the handle 14 is shaped so as to slightly protrude below the door plate 12, and when the door is closed, the handle 14 contacts the front surface of the lower shelf plate 24b. To do.

  The rail 10 has a U-shaped cross section composed of a hanging side 10b and an upper side 10a and a bottom side 10c substantially perpendicular to the hanging side 10b extending from the upper and lower edges of the hanging side 10b, respectively. It is attached to the left and right sides of the lower surface of the upper shelf board 24a with the opening (ie, the extending direction of the upper side 10a and the bottom side 10c) inside. The upper side 10a of the rail 10 is provided with a screw hole 19 for screwing the rail 10 to the upper shelf 24a, and the long side guide slit 11 for holding the roller 13 so that the roller 13 can run on the hanging side 10b. Is provided. In addition, the roller attachment part 11a for taking in / out the roller 13 is formed in the rear end of the guide slit 11 by providing a notch in the upper edge of the slit.

  Further, as shown in FIG. 3, a lateral blur prevention member 15 and a door plate support member 16 are provided at the front end of each rail 10. The lateral blur prevention member 15 is provided on the inner surface of the hanging side 10b of the rail 10, and as shown in FIG. 2 (b), by closing the gap generated between the inner surface of the rail 10 and the side surface of the door plate 12. There is a function to limit the left and right movement of the door plate 12. Further, the door plate support member 16 is provided on the upper surface of the bottom 10c of the rail, and is formed in a columnar shape with rounded corners. When the door plate 12 is slid, the lower surface of the door plate 12 (when the door is closed). The rear plate) has an effect of keeping the door plate 12 in a horizontal state and improving the sliding of the door plate 12. Further, by supporting the door plate 12 by the door plate support member 16, when the door plate 12 is slid, the lower surface of the door plate 12 is rubbed with the bottom 10c of the rail (FIG. 4 (a)), and the door is closed. When the door plate 12 is sufficiently pulled out, the door plate 12 is rotated downward, and the rear end (the upper end when the door is closed) of the door plate 12 contacts the upper side 10a of the rail (FIG. 4 ( b)) can be prevented. In addition, it is desirable that these lateral blur preventing member 15 and door plate support member 16 are formed of resin or the like.

  The detachable flip-up storage door mechanism of this embodiment is assembled and attached to a steel shelf as follows. First, as shown in FIG. 5 (a), the pair of rails 10 are arranged in parallel so that the openings are both directed inward. Next, the roller 13 of the door plate 12 is inserted into the guide slit 11 from the roller attachment portion 11a, and both rails 10 are fixed to the left and right sides of the bottom surface of the shelf plate 24 with screws 17. In addition, the folding | returning part 26 as shown to Fig.2 (a) is provided in the side edge part of the shelf 24 lower surface, and the rail 10 is attached to this folding | returning part 26. FIG. At that time, an L-shaped washer 18 is inserted between the rail 10 and the shelf plate 24 and stored on the shelf plate 24 side.

  In this way, the shelf plate 24 to which the door plate 12 is attached is attached to the main body of the steel shelf. As shown in FIG. 6 (a), the steel shelf body has two crossbars that cross in an X shape between a side plate 20 made of steel steel plate and a pair of side plate units made of two columns 21. 22 has a fixed structure. Instead of the crossbar, a plate material (back panel) may be used, and the side plate units may be fixed with one or a plurality of back panels. As an aspect in the case of using a plurality of back panels, for example, two back panels having substantially the same width as the interval between the side plate units and about half the height of the side plate units are used. A back panel having a width and a height that are substantially the same as the distance between both side plate units and the distance between the upper and lower shelf boards and a back panel attached to each level of the shelf can be considered.

  A side bar 23 is fixed between the columns 21 at a predetermined height on the side plate unit, and on the side bar 23, as shown in FIG. By hanging two fixed hooks 25, the shelf plate 24 is hung between the side plate units. Thereafter, as shown in FIG. 5 (b), the left and right L-shaped washers 18 are rotated out of the shelf plate 24 and protruded under the side bar 23. As a result, the shelf 24 sandwiches the side bar 23 from above and below by the hook 25 and the L-shaped washer 18, so that the shelf 24 (particularly the rear end) is fixed without moving up and down even when the door is opened and closed. Is done.

  Further, a roller detachment preventing member 30 made of rubber is attached to the rear end of the guide slit 11 of the rail 10. The roller detachment preventing member 30 is a rubber member having a slit as shown in FIG. 5C and is attached to the rail 10 by engaging the slit with the rear edge of the guide slit 11. The roller detachment prevention member 30 prevents the roller 13 from being detached from the rail 10 by closing a part of the roller attachment portion 11a, and also prevents impact caused by the roller 13 coming into contact with the rear end of the guide slit 11 when the door is stored. Has the effect of relaxing the sound.

  Thus, as shown in FIG. 7, a steel shelf with a flip-up type storage door is completed. When the door is open, as shown in the upper part of FIG. 7, the door plate 12 is stored immediately below the upper shelf plate 24, and when the door is closed, the handle 14 is held in front (the shelf Pull out (parallel to plate 24). At this time, the roller 13 travels along the guide slit 11 of the rail 10, but the groove 13a of the roller 13 is engaged with the upper and lower edges of the guide slit 11 as shown in FIG. For this reason, the left and right movement of the roller 13 is restricted. Furthermore, since the gap between the inner side surface of the rail 10 and the side surface of the door plate 12 is closed by the lateral blur preventing member 15, the left and right movement of the door plate 12 is restricted. For this reason, no matter which part of the handle 14 is gripped, the door plate 12 does not rattle and can be pulled out smoothly. At this time, the door plate support member provided on the bottom 10c of the rail 10 prevents the door plate 12 from being inclined and makes the door plate 12 slippery, so that the door can be easily slid even with a small force.

  When the door plate 12 is pulled out to the full, the door plate 12 rotates downward about the rotation axis of the roller 13 to cover the front surface of the space below the upper shelf plate 24. When the door plate 12 is in a substantially vertical state, the handle 14 provided on the door plate 12 comes into contact with the front surface of the lower shelf plate 24, and the rotation of the door plate 12 is stopped. A cushion 31 made of rubber or the like is affixed to a portion of the lower shelf plate 24 in contact with the handle 14 in order to reduce the impact and sound when the door is closed.

  Further, as shown in FIG. 2 (a), the rotation shaft of the roller 13 is provided slightly rearward (lower side in FIG. 2 (a)) on both sides of the upper end of the door plate 12, and further, the door plate. The center of gravity of 12 is positioned closer to the front than the center of the door plate 12 by the handle 14 provided on the front surface thereof, so that when the door is closed, the door plate 12 has a moment in the rear direction (inside the shelf). Works. For this reason, the handle 14 is biased to the front surface of the lower shelf plate 24b, and the swinging of the door plate 12 due to vibration or the like is prevented.

  Further, the front end portion of the rail bottom 10c is provided with a portion (folded portion 10d) that is bent substantially vertically downward, and when the door is closed, the rear surface of the door plate 12 and the bent portion 10d. As the handle 14 is in contact with each other, the front plate 12 serves to stop the rotation of the door plate 12.

  On the other hand, when opening the door, the handle plate 14 is held and the door plate 12 is rotated upward until it is substantially parallel to the shelf plate 24, and then the door plate 12 is pushed backward. At this time, similarly to when the door is pulled out, the door plate 12 is slid smoothly and easily by the action of the groove 13a of the roller 13, the guide slit 11 of the rail 10, the lateral blur prevention member 15, and the door plate support member 16. be able to.

  As described above, since the rail 10 is fixed to the upper shelf 24a with the screw 17, it can be easily attached to and detached from the shelf as needed. Therefore, for example, for a shelf having a plurality of spaces surrounded by two side plates and two upper and lower shelf plates, a door is provided only in a part of the plurality of spaces, depending on the purpose of use, etc. The user can freely lay out. At this time, as shown in FIG. 8, at least a plurality of types of detachable flip-up storage door mechanisms having different colors of the door plate 12 are attached to the plurality of spaces according to the application. Is desirable. In such a case, it is more desirable that the color scheme of the door plate is a combination of colors (for example, blue and yellow-green) that can be easily distinguished by color-impaired people.
