Description

  The present invention relates to a cabinet for storing articles by opening and closing an opening / closing door attached to an offset position.

  Conventionally, in food stores such as supermarkets and convenience stores, opening portions for taking out products are formed diagonally, and the shelf area located on the upper side of the shelf area is secured while securing a large shelf area on the lower shelf side. Food display shelves (showcases) that are narrower than the lower shelves are used. In such a food display shelf, the user can see the product placed on the lower shelf without being obstructed by the upper shelf, or the user can take out the lower product just by bending slightly. There is convenience in that it is easy.

  Moreover, in such a food display shelf, in order to maintain a sanitary state, an inclined door may be provided so as to cover an opening portion formed obliquely. The inclined door is formed in a flat plate shape with glass or the like, and is attached in a state of being inclined in accordance with the inclination of the opening portion. Moreover, the upper guide rail attached diagonally according to the inclination mentioned above is provided in the upper part of this inclination door. The inclined door is attached to the main body portion, extends obliquely downward from the upper guide rail toward the near side, and is in a position offset (shifted) toward the near side with respect to the upper guide rail. The inclined door can move in the opening and closing direction (left and right direction when the opening is viewed in front) while being inclined along the upper guide rail (see, for example, Patent Document 1).

  There is also a food display shelf that is not inclined, but is arranged at a position where the door is offset to the near side of the upper guide rail. For example, as shown in Patent Document 2 (especially see FIG. 3), there is a cross-sectional shape of the open / close door formed in a substantially L-shape that is inverted up and down, The open / close door is formed so as to extend substantially horizontally from the upper guide rail to the near side and to be lowered substantially vertically from the near end portion. Such a food display shelf is also known to have a high display effect because it can make it easy to visually check the products displayed inside through the glass.

  On the other hand, with a general opening / closing door that is mounted with the upper guide rail suspended almost vertically (with the opening / closing door not offset), the door is forcibly moved to the fully closed state when the door is closed. Closer technology is known. According to this closer, the door is not left in a half-open state, and is used as a sanitary and dust-proof measure (see, for example, Patent Document 3).

JP 2008-206640 A JP 2009-131435 A JP2013-249630A

  In the food display shelf described above, it is not preferable that the door is left in a half-open state from the hygienic aspect of preventing dust. However, there has been no food display shelf that attempts to forcibly close the open / close door at the offset position with a closer.

  The reason is that a load acts diagonally downward on the guide rail that receives the upper part of the door toward the center of gravity of the offset door. For example, when a closer is provided in an upper guide rail that is obliquely attached to an inclined door as in Patent Document 1, a load acting obliquely downward is received obliquely in the upper guide rail. This is because does not work smoothly.

  In addition, even when the door is provided offset to the front side as in Patent Document 2, if a closer is provided in the upper guide rail as in Patent Document 1, a load acting obliquely downward is applied to the upper guide rail. It will be received diagonally in the rail, and the same problem will arise.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a cabinet in which a closer for an open / close door located at an offset position can be provided.

  In order to solve the above problems, the present invention is a cabinet having an upper guide rail that supports an upper part of an open / close door, the open / close door being attached to a position that is offset to the near side of the upper guide rail, The open / close door is a sliding door, and includes a closer that forcibly moves the open / close door to a closed position when the open / close door is closed.

  In addition, the closer is attached to the upper guide rail side, and a door body engaging body that is suspended in a state in which the opening and closing door is offset is provided on the opening and closing door side. A capturing protrusion may be provided that protrudes toward the closer in a state where the opening and closing door is offset and suspended, and is captured by the closer and forcibly pulled in the closing direction.

  Further, the upper guide rail is provided with a lower rail and an upper rail extending in the opening / closing direction of the opening / closing door and spaced apart in the vertical direction, and the door body engaging body includes the lower rail A traveling roller that is in contact with the upper rail and does not contact the upper rail, and a posture control roller that is in contact with the upper rail and rolls and does not contact the lower rail may be provided.

Furthermore, the traveling roller and the attitude control roller may be rotatably attached by a rotation shaft extending in the front-rear direction, and may be arranged so as to be shifted in a direction substantially perpendicular to the opening / closing direction in the vertical direction.
Further, the traveling roller and the attitude control roller may be rotatably attached by a rotation shaft extending in the front-rear direction, and may be arranged in a horizontal direction so as to be shifted in a direction substantially orthogonal to the opening / closing direction.

  Moreover, the said attitude | position control roller may be rotatably attached by the rotating shaft which has an angle with respect to the rotating shaft of the said traveling roller.

  The cabinet according to the present invention includes a closer that forcibly moves the open / close door to the closed position when the open / close door is closed, so that the open / close door is not left in a half-open state. Compared with the half-open state, dust and the like can be made difficult to enter the cabinet. In particular, in a cabinet used for a food display shelf such as a food department, it is useful to be able to keep the hygiene in the cabinet.

It has been.

  The upper rail 13 extends inward from substantially the center position in the vertical direction of each of the rear side surface portion 11c and the front side surface portion 11d of the guide rail body 11 so as to cover the upper side of the lower rail 12. Similar to the rail 12, a gap is provided so that these tip portions are separated from each other. In addition, the door body engaging body 30 mentioned later for details is inserted in the clearance gap between the lower rail 12 and the upper rail 13.

  A traveling roller rolling surface 12a is formed on the upper surface of the lower rail 12 so as to be recessed downward in an arc shape. On the other hand, on the lower surface of the upper rail 13, a posture control roller rolling surface 13 a that is recessed upward in an arc shape is formed.

  On the upper side of the upper rail 13, there is provided a closer mounting portion 14 defined in a substantially rectangular shape by the upper surface of the upper rail 13. A closer 60, which will be described in detail later, is provided on the closer mounting portion 14. Are attached at predetermined positions.

  As shown in FIG. 6, the lower surface of the mounting projection 11a is superimposed on the upper surface of the ceiling portion 5 of the food display shelf main body 2, and a screw (not shown) is fastened from above so that the upper guide rail 10 is attached to the ceiling. It is fixed to the part 5. Further, the decorative cover 20 has a hook portion 21a provided at the rear end thereof hooked on the receiving portion of the mounting projection 11a, and a locking portion 21b provided at the lower front side engaged with the decorative cover fixing projection 11b. It is attached detachably by doing.

  Inside the upper guide rail 10, door body engaging bodies 30 and 70 are inserted from the end portion of the upper guide rail 10. This door body engaging body 30 is for suspending the front door 3a of the inclined door 3 downward, and the door body engaging body 70 suspends the rear door 3b of the inclined door 3 downward. It is for lowering. These door body engaging bodies 30 and 70 are moved in the left-right direction of the upper guide rail 10 by a traveling roller 34 and a posture control roller 35, which will be described in detail later, rolling on the rolling surfaces of the lower rail 12 and the upper rail 13. You can move freely.

  The door body engaging bodies 30 and 70 have different axial lengths in the front-rear direction of a rotating shaft 35a, which will be described in detail later, and different mounting positions in the front-rear direction of the attitude control roller 35. Are all the same. More specifically, as shown in FIG. 5 and FIG. 6, the front door body engaging body 30 (running on the front side inside the upper guide rail 10) is rotated 180 degrees horizontally, What changed the position of the direction is the rear door body engaging body 70 (runs on the rear side inside the upper guide rail 10). Therefore, in the following description, the front door body engaging body 30 will be described, and description of the rear door body engaging body 70 other than the portion of the posture control roller 35 will be omitted. Moreover, since all the functions of the components used by the door body engaging bodies 30 and 70 are the same, the description will be made with the same reference numerals.

  FIG. 8 is a front view showing a state where the hook attachment member 40 is attached to the door body engaging body 30, and FIG. 9 is a plan view of FIG. The door opening and closing directions shown in FIGS. 8 and 9 are the opening and closing directions of the front door 3a.

  The door body engaging body 30 includes a main body portion 31 formed by bending a sheet metal into a substantially L shape. The main body portion 31 includes an upright portion 31a extending in the vertical direction and a horizontal portion 31b extending in the front-rear direction. ing.

  On the left side of the standing portion 31a, a capturing protruding piece 32 protruding upward from the upper end portion is provided. A buffer member 33 such as rubber is attached to the upper end of the capturing protruding piece 32 so as to cover the outer periphery thereof.

  In addition, two rotating shafts 34a are provided on the standing portion 31a with a space in the left-right direction so as to protrude to the front side in the front-rear direction of the standing portion 31a. These rotating shafts 34a are rotatably attached in a state where the traveling roller 34 stands up (a state in which the traveling roller 34 faces in the vertical direction). The rotary shaft 34a and the traveling roller 34 are attached so that the height position in the vertical direction is the same (see FIG. 8), and the position in the front-rear direction is also the same (see FIG. 9).

  Furthermore, the upright part 31a is provided with a rotating shaft 35a that protrudes forward in the front-rear direction of the upright part 31a between the two right and left traveling rollers. The posture control roller 35 is rotatably attached to the rotary shaft 35a in a standing state.

  As shown in FIG. 8, the rotary shaft 35 a and the attitude control roller 35 have a height position in the vertical direction (in the vertical direction, a direction substantially perpendicular to the opening / closing direction of the front door 3 a) of the L1 dimension than the travel roller 34. They are arranged so as to be higher. Further, as shown in FIG. 9, the rotary shaft 35 a and the attitude control roller 35 have a position in the front-rear direction (a direction that is substantially orthogonal to the opening / closing direction of the front door 3 a in the horizontal direction) of the L2 dimension as compared to the traveling roller 34. They are arranged so as to be shifted to the rear side (see FIG. 9).

  Here, the attitude control roller 35 of the rear door body engaging body 70 is arranged so that the position in the front-rear direction shown in FIG. That is, in a state where the door body engaging body 70 is incorporated in the upper guide rail 10, the posture control roller 35 is located on the rear side of the traveling roller 34 in the same manner as the posture control roller 35 of the front door body engaging body 30. Come to be located.

  As shown in FIG. 9, the outer peripheral shapes of the traveling roller 34 and the attitude control roller 35 are formed in an arc shape in which the central portion is swollen.

  Moreover, the diameters of the traveling roller 34 and the attitude control roller 35 are formed to be smaller than the distance in the vertical direction between the lower rail 12 and the upper rail 13. More specifically, the distance between the lower rail 12 and the upper rail 13 is a dimension obtained by adding the length of the L1 dimension described above to the diameters of the traveling roller 34 and the attitude control roller 35.

  A mounting pin 36 extending downward from the lower surface is attached to the horizontal portion 31b. A hook attachment member 40 is detachably attached to the attachment pin 36. Further, as shown in FIGS. 5 and 6, the hook attaching member 40 is attached to the hook attaching member 40.

  As shown in FIGS. 1 and 4, the hook member 50 has a length substantially equal to the length of the front door 3 a in the left-right direction. Also. As shown in FIGS. 5 and 6, the hook member 50 is provided with a hook 51 having a substantially U-shaped cross section on the lower side. Further, a cylindrical portion 52 having a circular cross section is formed at the tip of the hook 51.

  On the other hand, a door mounting member 6 is provided on the upper portion of the front door 3a as shown in FIG. The door mounting member 6 is formed with an engaging portion 6 a that engages with the cylindrical portion 52 at the upper portion thereof. The engaging portion 6 a is formed in an arc shape having an inner diameter substantially equal to the diameter of the cylindrical portion 52. With such a structure, the front door 3a can be rotated in the circumferential direction of the cylindrical portion 52 in a state where the engaging portion 6a is engaged with the cylindrical portion 52, as shown in FIG. 1 and FIG. In addition, the front door 3a can be attached in an inclined state in accordance with the inclination of the opening of the food display shelf 1. In addition, by allowing the front door 3a to rotate in the circumferential direction of the cylindrical portion 52, even if the inclination angle of the opening of the food display shelf 1 is different, this structure can be used.

  As described above, the front door 3a can be adapted to various angles through the hook attachment member 40 and the hook member 50 to the door body engaging body 30 traveling on the upper guide rail 10, and is suspended in an inclined state. Will be attached.

  In addition, the lower roller 7 is provided in the lower part of the inclined door 3, as shown in FIG. The lower roller 7 is obliquely placed on the rolling surface of the lower guide rail 8 disposed at the front end portion of the shelf 4a, and extends along the lower guide rail 8 when the front door 3a is opened and closed. Can move freely in the left and right direction.

  On the other hand, a closer 60 shown in FIG. 10 is attached at a predetermined position in the left-right direction to the closer attaching portion 14 of the upper guide rail 10 on the food display shelf main body 2 side. The closer 60 is formed with an engagement body moving elongated hole 62 extending from the door opening side end to the door closing side below the substantially rectangular parallelepiped main body 61. When the front door 3a is closed, the engagement body moving elongated hole 62 is provided with the capturing protrusion 32 for capturing the door body engagement body 30 (see FIGS. 5 and 6). Engaged and captured by the locking body 63. The locking body 63 forcibly moves the capturing protruding piece 32 toward the door closing side slowly by a retracting spring member (not shown) provided in the main body 61 or a buffer damper (not shown). Works to pull in. As a result, the front door 3a suspended from the door engaging body 30 is forcibly moved to a fully closed position.

  The closer 60 described above is the same as that used in a general sliding door device in which the open / close door is attached substantially vertically. Since the internal structure, mounting position, function and action of the closer 60 are known techniques (for example, refer to Patent Document 2), detailed description thereof will be omitted.

  Next, operation | movement and an effect | action of the food display shelf 1 which has the inclined door which concerns on embodiment of this invention are demonstrated in detail. FIG. 11 is an enlarged view showing a control roller traveling in the upper guide rail. In addition, since operation | movement and an effect | action of the front side door 3a and the rear side door 3b are the same, the front side door 3a is demonstrated in the following description.

  As shown in FIG. 6, when the engaging portion 6a of the front door 3a is engaged with the columnar portion 52 of the hook member 50 and the front door 3a is attached in an inclined state, the columnar portion 52 depends on the weight of the front door 3a. A force that is pulled diagonally forward and downward along the inclination of the front door 3a acts. Thus, a clockwise rotational moment acts on the door body engaging body 30 located on the upper side of the cylindrical portion 52 in a direction in which the door body is about to fall down. This rotational moment tilts and shifts the position of the capturing protrusion piece 32 to the rear side, and hinders the operation of the catcher 63 of the closer 60 to accurately capture the capturing protrusion piece 32. Further, when the door body engaging body 30 is largely inclined, the traveling roller 34 may come into contact with both the lower rail 12 and the upper rail 13 and the opening / closing operation of the front door 3a may be locked.

  In order to receive this rotational moment, the door body engaging body 30 is provided with a posture control roller 35 in addition to the traveling roller 34. More specifically, the traveling roller 34 contacts the lower rail 12 of the upper guide rail 10 and rolls on the traveling roller rolling surface 12a when the front door 3a is opened and closed. Further, the traveling roller 34 has a gap with the upper rail 13 during traveling, and does not come into contact therewith.

  On the other hand, as shown in FIG. 11, the posture control roller 35 is different from the traveling roller 34 and is in contact with the upper rail 13 of the upper guide rail 10 during the opening / closing operation of the front door 3 a, and the posture control roller rolling surface. Roll on 13a. Further, the posture control roller 35 is not in contact with the lower rail 12 and the gap S during traveling.

  The traveling roller 34 and the attitude control roller 35 come into contact with the lower rail 12 and the upper rail 13 respectively to resist the rotational moment described above, and to make the door body engaging body 30 less inclined to the rear side. Act on. Accordingly, the capturing protruding piece 32 always protrudes upward toward the engaging body moving oblong hole 62 of the closer 60 regardless of the inclination angle or the weight of the suspended front door 3a. The 60 locking members 63 accurately capture the capturing protrusions 32.

  In addition, the posture control roller 35 is arranged to be shifted rearwardly by the L2 dimension with respect to the traveling roller 34, so that the posture control roller 35 receives a larger rotational moment and stretches. Therefore, compared with the case where it arrange | positions linearly without shifting, the door body engaging body 30 becomes difficult to incline to the back side. Accordingly, the locking body 63 of the closer 60 can accurately capture the capturing protruding piece 32.

  Furthermore, as shown in FIG. 5, the door body engaging bodies 30 and 70 are attached so as to be inclined to the front side in a state before the inclined door 3 is attached. Then, when the inclined door 3 is attached and the above-described rotational moment is applied, the capturing protruding piece 32 is substantially vertical.

  According to the food display shelf 1 having the inclined door according to the embodiment of the present invention, when the inclined door 3 (the front door 3a and the rear door 3b) is closed, the inclined door 3 is forcibly moved to the closed position. Since the closing door is provided, the inclined door 3 is not left in a half-open state, and dust or the like can be prevented from entering the food display shelf 1 as compared with the half-open state. In particular, when used in a food display shelf 1 such as a food department, it is useful to be able to maintain internal hygiene.

  Further, a closer 60 is attached to the food display shelf body 2 side, and a door body engaging body 30 that is suspended in a state where the inclined door 3 is inclined is provided on the inclined door 3 side. Is provided with a capturing protruding piece 32 that protrudes toward the closer 60 in a state where the inclined door 3 is inclined and suspended, and is captured by the locking body 63 of the closer 60 and forcibly pulled in the closing direction. Therefore, the capturing protruding piece 32 protruding upward can be reliably captured by the locking body 63. Accordingly, the same closer 60 is used even if the inclined door 3 is attached at various angles or the door is suspended substantially vertically like a general sliding door device. be able to. Therefore, it is not necessary to modify the closer for the inclined door 3 or to have a complicated structure that receives a load acting in two directions by the weight of the inclined door 3 obliquely.

  Furthermore, the upper guide rail 10 extended along the opening / closing direction of the inclined door 3 is provided in the food display shelf main body 2 side, and the lower rail 12 and the upper rail 13 are spaced apart from the upper guide rail 10 in the up-down direction. The door engagement body 30 is in contact with the lower rail 12 and rolls, and is in contact with the upper rail 13. The traveling roller 34 is in contact with the upper rail 13 and rolls in contact with the lower rail 12. Since the posture control roller 35 that does not contact is provided, the rotational moment generated by the weight of the inclined door 3 can be received by these rollers 34 and 35. Thereby, since the door body engaging body 30 can be made difficult to incline to the rear side, the direction in which the capturing protruding piece 32 of the door body engaging body 30 protrudes is related to the inclination angle and the own weight of the suspended inclined door 3. Can always be kept constant. Therefore, the capturing protrusion 32 can be reliably captured by the locking body 63, and the closer 60 can be operated smoothly.

In order to make the operation smooth, it is conceivable to arrange two rollers for receiving two loads, the horizontal direction and the gravity direction, respectively. It can be made simpler. Therefore, the manufacturing cost of the cabinet 1 can be suppressed.
Furthermore, if two different directions of rollers are provided in the upper guide rail, or if a diagonally set roller is placed in the upper guide rail, the outer dimensions of the upper guide rail will be larger than necessary. Although the design is impaired such that the upper portion of the food display shelf protrudes greatly to the front side, according to the present configuration, these problems do not occur.
Furthermore, although the inclination angle of the inclined door 3 varies depending on the type of the food display shelf, it can be handled without trouble such as adjustment by receiving the rotational moment by the traveling roller 34 and the attitude control roller 35.

  Furthermore, since the traveling roller 34 and the posture control roller 35 are arranged by shifting by the L2 dimension in the front-rear direction, the door body engaging body 30 is less likely to be tilted rearward as compared to the case where the traveling roller 34 and the attitude control roller 35 are arranged without being shifted. be able to.

  Moreover, the outer peripheral shape of the traveling roller 34 and the posture control roller 35 is formed in an arc shape in which the central portion swells, and the traveling roller rolling surface 12a of the lower rail 12 and the posture control roller rolling surface 13a of the upper rail 13 are Since the rollers 34 and 35 are recessed in accordance with the arcuate shape, even if the rotational moment described above occurs, the outer peripheral portions of the rollers 34 and 35 and the rolling surfaces 12a and 13a are in arc contact, No excessive force is generated. Therefore, when opening / closing the inclined door 3, it can open / close smoothly, without the inclined door 3 being made.

  As mentioned above, although the cabinet which has the inclined door which concerns on embodiment of this invention was described, this invention is not limited to above-mentioned embodiment, Various deformation | transformation and change are based on the technical idea of this invention. Is possible.

  For example, in the present embodiment, as an example of a cabinet in which an opening / closing door is attached at a position offset to the near side of the upper guide rail 10, a cabinet 1 having an inclined door 3 attached so as to cover an inclined opening. However, the present invention is not limited to this. For example, even in a cabinet having an open / close door formed in a substantially L shape as disclosed in Patent Document 2, the same problem occurs as long as the open / close door is attached to an offset position. Therefore, by adopting the structure described in the present embodiment, the closer 60 can be operated smoothly as in the present embodiment.

  Further, in the upper guide rail 10 described in the present embodiment, the closer attaching portion 14 for attaching the closer 60 is provided on the upper side of the upper rail 13, and the capturing protruding piece 32 of the door body engaging body 30 is directed upward. Although protruding, it is not limited to this. For example, the closer attaching portion 14 may be formed on the rear side (back side) of the upper guide rail 10 and attached to the closer attaching portion so that the engaging body moving elongated hole 62 of the closer 60 faces the front side. In this case, the capturing protruding piece 32 is bent so as to protrude toward the rear side (toward the closer 60). Even in this case, the closer 60 can reliably capture the capturing protrusion 32 and can smoothly move the door in the closing direction. Thereby, the dimension of the up-down direction of an upper guide rail can be made small, and an upper guide rail can be made inconspicuous seeing from the outer side of a cabinet.

  Furthermore, although the two traveling rollers 34 and the one attitude control roller 35 are configured, the number is not limited to this. For example, the number of attached traveling rollers 34 and posture control rollers 35 can be increased or decreased depending on the weight and size of the front door 3a.

  In the present embodiment, the attitude control roller 35 is disposed between the two traveling rollers 34, but other arrangements may be employed. For example, the attitude control roller 35 may be arranged at a position outside the traveling roller 34 in the left-right direction. Further, two (or two or more) posture control rollers 35 may be arranged between the two traveling rollers 34.

  Furthermore, in the present embodiment, the posture control roller 35 is shifted to the rear side with respect to the traveling roller 34, but may be shifted to the front side in accordance with the direction in which the moment acts. Also by this, compared with the case where the traveling roller 34 and the attitude control roller 35 are arranged linearly in the traveling direction, the door body engaging body 30 can be made difficult to tilt.

  In the present embodiment, the rotating shafts 34a and 35a to which the traveling roller 34 and the posture control roller 35 are attached are provided so as to protrude forward in the front-rear direction, and the traveling roller 34 and the posture control roller 35 are raised. Although it is attached rotatably (in a state facing the up-down direction), it is not limited to this. For example, the traveling roller 34 is kept standing (the state disclosed in the present embodiment), and the rotation shaft 35a of the posture control roller 35 is attached to the rotation shaft 34a of the traveling roller 34 by being inclined by 90 degrees, and the posture control roller It can also be attached rotatably in a state in which 34 is directed in the horizontal direction (a state in which it is directed in the front-rear direction). In this case, the upper rail 13 for the posture control roller 35 to contact and roll must also be inclined by 90 degrees. Even in this case, the posture control roller 35 is in contact with only the upper rail 13 and can receive a rotational moment by the posture control roller 35.

  Alternatively, the posture control roller 34 may be attached to the traveling roller 35 at an angle other than 90 degrees. Furthermore, the traveling roller 34 and the posture control roller 35 may be attached in a direction other than the front-rear direction or the horizontal direction. In this state, the posture control roller 34 may be attached to the traveling roller 35 at an angle. Good.
