Description

  The present invention relates to a movable shelf, and more specifically, on a rail laid on the floor, a frame having wheels that can roll along the rail is placed, and the shelf is placed on the frame. The present invention relates to a movable shelf that is erected and whose shelf is movable when wheels roll on the rail.

  Conventionally, for example, as shown in Patent Document 1, a shelf is erected on a carriage provided with wheels, and the carriage rolls on a rail laid on the floor, whereby the shelf becomes movable along the rail. Mobile shelves are well known.

  For example, as shown in FIG. 9, a plurality of shelves 1 are installed so as to be movable on two rails 2 and the shelves 1 are moved along the rails 2 as necessary. A working space 10 is secured. Accordingly, since it is not necessary to install the shelves 1 with an interval between them, a large number of shelves can be installed in a space-saving manner and are widely used.

  In the moving shelf shown in FIG. 9, when the shelf 1 is moved, the handle 1 provided on the front panel 11 of the shelf 1 is grasped and the shelf 1 is manually moved along the rail 2 in the direction of arrow A. In addition to such manual moving means, there are a handle system in which the shelf is moved in a desired direction by turning the handle, and an electric system in which a motor is connected to the wheels to electrically move the shelf.

  In such a conventional moving shelf, once the shape and moving method of the shelf are selected and manufactured, the shelf is mounted on a frame fixed to a certain shape by welding, and a number of bolts, rivets, or welding is performed. Can be attached firmly. Further, the saddle holding the wheel is fixed to the frame by welding.

Therefore, for example, changing the shape of the shelf such as increasing the number of stations in order to widen the frontage of the shelf 1 has been practically impossible because the frame itself has to be changed.

  FIG. 1 shows an arrangement example of movable shelves according to the present invention, and three manual shelves 1 are provided on a rail 2.

  Two rails 2 are laid at both the front and back ends of the shelf 1, and another rail 2 is laid at the center depending on the depth dimension of the shelf 1 and the weight of the articles stored in the shelf 1. .

  The front panel 11 of each shelf 1 is provided with a handle 12, and the shelf 1 moves to the left and right as indicated by the arrow A in the figure by grasping the handle 12 and pushing or pulling it in either direction. A space 10 for loading and unloading is formed. The arrangement of the shelves 1 is not limited to the example in FIG. 1, and three or more shelves 1 may be arranged on the rails 2. The width of each shelf 1 can be selected arbitrarily. In addition to the manual method of FIG. 1, the method for moving the shelf 1 is a handle method for moving the shelf in a desired direction by turning the handle, or an electric motor for moving the shelf electrically by connecting a motor to the wheel. There are methods.

  FIG. 2 is a plan view showing the floor structure of the movable shelf in FIG.

  Three rails 2 made of an extruded material made of a metal such as an aluminum alloy are laid in parallel on the floor surface at intervals corresponding to the depth dimension of the shelf 1. The rail 2 can be set to an arbitrary length and is determined in accordance with the dimensions and arrangement of the shelf 1. The rails 2 are modularized and formed to have a certain length, and are connected so as to have a required length.

  A floor panel 3 is fitted between the rails 2 and 2. Slope panels 4 are fitted on the outer side surfaces of the rails 2 at the left and right ends. End covers 5 that cover the ends of the rails 2 are attached to both ends of each rail 2 in the longitudinal direction, along with the edges of the floor panel 3 and the slope panel 4 arranged at the ends. Thus, the floor structure provided with the rails 2 is configured. Further, stoppers 6 are attached to both ends of each rail 2 in the longitudinal direction from above the end cover 5.

  FIG. 3 is an exploded perspective view of components constituting the floor structure of FIG.

  The rail 2 is manufactured by modularizing a certain length, and is connected to a length required at a construction site. The rails 2 of each module are connected to each other by inserting a connecting member 23 into the cavity 20 at each end of the rails 2 to be connected. Two linear protrusions 23 a are formed on each of the four side surfaces around the connecting member 23. By these protrusions 23a, the connecting member 23 absorbs a dimensional error with respect to the inner wall surface of the hollow portion 20, makes a line contact without rattling, and a reliable holding function is obtained with a smooth mounting operation. After inserting the connecting member 23 and temporarily joining the rails 2 together, the rails 2 and the connecting member 23 are fastened together by tapping screws (not shown) through the countersunk holes 20b at the ends of the rails, and the rails 2 are connected and fixed. .

  In order to lay the rail 2 horizontally, a liner 24 is used. FIG. 4 shows an example of use of the liner 24. The liner 24 is made of a thin metal plate so that it can be finely adjusted with respect to slight unevenness of the floor 30, and a plurality of liners 24 are stacked and used as necessary. By using the number of liners 24 increased or decreased depending on the installation position, the rail 2 can be laid horizontally without rattling. The liner 24 has substantially the same width as the rail 2, and a plurality of protrusions 24a are formed on one side by punching. When the liners 24 are stacked, the protrusions 24a on the upper surface of the liner 24 below the liners 24 that are in contact with each other are engaged with the recess 24b on the lower surface of the upper liner 24 so that the liner 24 is laterally displaced or detached. prevent. Further, by forming a recess or hole that engages with the protrusion 24a on the bottom surface of the rail 2, the rail 2 and the liner 24 are engaged and held without shifting, and the rail 2 and the liner can be used without using an anchor bolt or the like. 24 can be integrated.

  A U-shaped notch 32 is formed in the bent side piece 31 (FIG. 3) of the floor panel 3. The notch 32 is locked on the side piece 22a of the rail 2, and the floor panel 3 is fitted between the rails 2 (only one in the figure) on both sides. Reference numeral 33 denotes a reinforcing rib of the floor panel 3.

  The slope panel 4 is attached by fitting the locking portion 41 on the back surface thereof onto the side piece 22a of the rail 2.

  An end cover 5 is fixed to the end of the rail 2 together with a stopper 6. These are fixed to the rail 2 by, for example, a screw (not shown) screwed into a mounting nut inserted into the groove 21 of the rail 2. It should be noted that both end portions 5 a of the end cover 5 are preferably bendable so that the angle changes according to the inclination of the slope panel 4.

  Thus, the construction of the floor structure can be performed without using fixing means for the building-side floor such as anchor bolts. In this case, even if there is no anchor bolt or the like, the parallel rails 2 are fixed by the end cover 5 at both ends, and the rails 2 are connected by the floor panel 3. A strong frame combined together is formed. Therefore, even if the building is shaken by an earthquake, the frame body composed of the rails 2 and the floor panels 3 does not collapse and can support the shelf stably. Further, since no anchor bolt or the like is used, it is possible to easily increase or decrease the rail 2 and the accompanying increase or decrease of the floor panel 3 or the like.

When the rails 2 are laid in three rows as shown in FIG. 1, the saddle bodies 71 that are arranged in three rows on each rail 2 and are juxtaposed on each rail 2 are connected by a saddle joint plate 72. The The saddle joint plate 72 is attached by using attachments 73 fixed with bolts or the like at both ends inside the saddle body 71. The attachment 73 is formed with two upper and lower locking holes 73a at symmetrical positions when viewed from the center with respect to the center. By locking the claw 72a of the saddle joint plate 72 in the locking hole 73a, the saddle body 71 can be connected to each other by attaching the saddle joint plate 72 by a simple operation from the outside of the saddle body 71. . In this case, the saddle joint plate 72 on the left side of the saddle 70 as viewed from the front is locked in the locking hole 73a on the left side of the mounting tool 73 (inside the frame from the center of the mounting tool).

  The attachment 73 has a hollow inside, and the wheel 9 is accommodated therein. On both side surfaces of the saddle body 71, inverted U-shaped cutouts 71a are formed, and the shafts 91 of the wheels 9 are fitted therein. A saddle 70 is configured by the saddle body 71, the attachment 73 attached to both ends of the saddle body 71, and the wheels 9.

  The shelf fixtures 16 are fixed to both ends of the upper surface of the saddle body 71. The shelf fixture 16 is fixed by placing the column mounting surface 16a on the end side of the saddle body 71, and the column 13 is mounted on the column mounting surface 16a. The column 13 is provided with locking holes 13a and 13b for locking the locking claws 14a and 15a formed in the long beam 14 and the short beam 15, respectively. The long beam 14 and the short beam 15 are attached by inserting and engaging claws 14a and 15a into locking holes 13a and 13b provided on the respective mounting surfaces of the support column 13.

  In this case, the support column 13 is provided with locking holes 13a and 13b symmetrically with respect to the center in the vertical direction when viewed from the front. The long beam 14 is attached by using the locking hole 13a on the inner side (left side in the figure) of the frame similar to the saddle joint plate 72 described above. The short beam 15 is attached using a locking hole 13b on the inner side of the underframe (the left surface of the column 13 in the figure). In order to make the structure easy to see, the short beam 5 is drawn on the right side of the support column 13 in FIG. 6, but it is actually attached to the left side of the support column 13.

  FIG. 7 is an enlarged view of a portion B in FIG. 5 and shows a configuration of the lower end portion of the shelf 1. Moreover, FIG. 8 is a CC arrow view of FIG. 5, and shows the structure of the shelf 1 lower end part seen from the direction at right angles to FIG.

  The cross section of the rail 2 has a rectangular cross section-shaped cavity 20 at the center, and two rows of grooves 21 and 22 are formed adjacent to each other on both sides thereof so as to be symmetrical. The grooves 21 and 22 are formed by side pieces 21a and 22a, respectively. The inner side piece 21a is bent in an L-shaped cross section, and a bent portion 21b is formed in a bowl shape.

  Further, a fall prevention tool 29 is attached to the lower part of the saddle 70, for example, fixed to the lower part of the compression tool 28. The fall prevention tool 29 moves in the groove 21 of the rail 2 and when the shelf 1 is inclined, the fall prevention tool 29 is caught by the bent portion 21b constituting the upper edge of the groove 21 to prevent the fall. The compression tool 28 and the overturn prevention tool 29 are attached to a position inside the saddle body 71 that is slightly shifted inward from the position of the wheel 9.

  The saddle 70 having the wheel 9 as described above is placed on the rail 2, and the column 13 of the shelf 1 is attached on the saddle 70. The shelf fixture 16 is fixed to both ends of the saddle body 71 with bolts 8a. The open surface of the column 13 having a U-shaped cross section is placed opposite to the column mounting surface 16a of both shelf fixtures 16, and the long beam 14 in the depth direction (perpendicular to the rail 2) is mounted on the column 13. And the short beam 15 of the direction along the rail 2 is attached. As described above, the column 13 and the long beam 14 and the short beam 15 are connected to the locking holes 13a and 13b provided in the column 13 by locking the claw portions 14a and 15a of the long beam 14 and the short beam 15, respectively. By the locking means 18,19. That is, the claws 15a of the short beam 15 are inserted into the locking holes 13b provided on the opposite side surfaces of the column 13 having a U-shaped cross section. Further, of the two upper and lower locking holes 13 a provided symmetrically with respect to the center on the front surface of the support column 13, the locking holes 13 a located inside the underframe 7 are inserted into the claws of the long beam 14. 14a is inserted. As shown in FIG. 5, the locking holes 13 a and 13 b are provided at the upper end portion and the lower end portion of the support column 13, and the long beam 14 and the short beam 15 are attached to both the upper and lower sides.

  In this way, the short beam 15 and the long beam 14 are attached to the upper end portion and the lower end portion of the support column 13, respectively, to form the shelf 1 having the frame structure. The shelf 1 is set on a frame 7 made of a saddle 70. In this case, the short beam 15 at the lower end of the support column 13 is disposed outside the side surface 16b (FIG. 6) of the shelf fixture 16 inside the underframe 7, and the bolt 8b is inserted from the outside of the shelf fixture 16 to fix the shelf fixture. The short beam 15 is fixed to the shelf fixture 16 by being screwed into the nut 16 c (FIG. 6) inside the 16. Thus, the shelf 1 and the underframe 7 are connected and integrated with each other via the shelf fixture 16.

  As described above, a framework having a frame structure composed of the support columns 13 and the long beams 14 and the short beams 15 is formed, and side plates and shelf plates that form storage spaces for articles are attached to the framework to form the shelf 1. Is done.

  In the case of a moving shelf with such a structure, when it is desired to increase the size of the shelf, the existing frame and the shelf above it are not disassembled, and a new frame and shelf are added as they are. Can be easily increased. In addition, even when the number of stations is reduced, it is possible to easily remove the connected frames and shelves to form a small movable shelf.

  Further, as an incidental effect, the position of the support column 13 is directly above the wheel 9, so that the force from the support column 13 acts on the directly below wheel 9. Therefore, the wobbling or the like hardly occurs when the wheel 9 rolls, and the movement is stabilized. In addition, since a large bending stress does not act on the saddle 70, the parts are not easily damaged, and the saddle body 71 can be formed of a thin plate.

  The present invention is applied to a moving shelf having wheels that roll on rails. Note that the present invention can be applied to any type regardless of the weight of the stored items on the shelf and the wheel moving means such as manual or electric. The shelves standing on the frame are not limited to bookshelves and display shelves, but furniture that is installed indoors, such as lockers, storages, partitions, counters, or tables with heavy tables and desks It can be applied to the case where a moving structure is used.
