Description

[Detailed description of the invention] This invention relates to a structure for mounting a roller frame on a fluidized shelf, and its purpose is to use bolts, screws, etc. to install a fluidized shelf, that is, a roller frame that is installed between the front and rear horizontal frames of the shelf. The main feature is that it enables easy and firm installation without loosening or wobbling.

The conventional roller frame 1 was installed by tightening the bottom plate a of the frame with bolts and nuts either directly or via a stopper plate b, as shown in FIG. This is not only troublesome, but also has the disadvantage that the roller frame may wobble due to loosening of the fastened portion.

This proposal was devised in view of such conventional problems, and will be explained below with reference to the attached example drawings.The roller frame 1 is a fixed frame in which an opening strip 3 is formed with opening edges 2 left on both sides of the lower surface. Rollers 4 are provided at intervals so as to protrude upward from upper surface openings 5, and the horizontal frames 6 at the front and rear of the shelf A that erect and support the roller frame 1 are made of angle rods, and the horizontal surfaces thereof are used to attach the roller frame 1. A connecting fitting 10 for connecting and fixing the roller frame 1 and the horizontal frame 6 is a vertical support edge 7 having a notch 12 for fitting and locking the opening edge 2. The piece 11 can be fitted into the roller frame 1, and the mounting piece 13, which is horizontal to the vertical piece 11, can be engaged with a connecting hole 8 formed in the support edge 7 of the horizontal frame 6. .

More specifically, the connecting fitting 10 is, for example, a second
As shown in the embodiment shown in the figure, cut and raised pieces 14 are provided at the ends of both sides of the mounting piece 13 to closely fit on the outside of both side plates 1' of the roller frame 1, and upwardly directed protrusions are provided at the ends of the mounting piece 13. 16 is formed in a stepped shape with a predetermined gap L between it and the mounting piece 13, and downward protrusions 17, 17 are formed at appropriate locations on the mounting piece 13. To attach the roller frame 1 to the horizontal frame 6 using the connecting fittings 10, first fit the vertical pieces 11 of the mounting fittings 10 into the roller frame 1, and then remove the vertical pieces 11.
Fit the opening edge 2 into the notch 12 of the roller frame, and attach the roller frame side plates 1', 1' to the cut and raised pieces 1 of the mounting bracket.
Roller frame 1 is tightly fitted between 4 and 14.
Attach the mounting bracket 10 to the end of the mounting bracket 10, and then press the mounting bracket 10 in this state in the direction shown by the arrow in FIG. Support edge 7 of horizontal frame 6
The support edge 7 is fitted with the mounting piece 13 and the bent piece 15.
The upward protrusion 16 of the bent piece 15 is fitted into the connecting hole 8 of the support edge 7, and the bent part 15' of the bent piece 15 and the downward protrusions 17, 17 of the mounting piece 13 are supported. The connecting fitting 10 and the horizontal frame 6 are connected by contacting the front edge of the edge 7, and the roller frame 1 and the horizontal frame 6 are connected via the connecting fitting 10. In addition, under this state in which the connection is completed, the end surface 1'' of the roller frame 1 is in contact with the vertical edge 9 of the horizontal frame 6. Also, depending on various conditions such as the shape and size of the shelf body A, the connection fittings 1
0 to the horizontal frame 6, the connecting fitting 10
The roller frame 1 may be attached to the roller frame 1.

On the other hand, in the connecting fitting 10 shown in the embodiment shown in FIG. 3, the vertical piece 11 has the same structure as described above, and the mounting piece
This is an example of a configuration in which the bent piece 15 formed in 3 is formed in a stepped manner near the base of the mounting piece 13, and the tip of the mounting piece has a hook that fits into the connecting hole 8 instead of the above-mentioned upward protrusion 16. The connecting piece 18 to be fastened is formed by bending and extending the connecting piece 18 with its height approximately equal to the thickness of the mounting piece.
is fitted into the connecting hole 8 of the support edge 7 of the horizontal frame 6 from above, and the bent portion 15' of the bending piece 15 is brought into contact with the front end of the support edge 7 while the mounting piece 13 is brought into close contact with the upper surface of the support edge 7. They are attached in contact with each other, and at the same time that the front surface of the supporting edge and the bent portion 15' of the bent piece 15 come into contact, the stepped portion 18' of the connecting piece 18 is fitted into and latched to the edge of the opening 8. In addition, 19 in Figure 1
is the side frame of shelf A, 20 is the receiving frame, 2
1 is a middle crosspiece, 22 is a reinforcing frame, and 23 is a support.

According to the roller frame mounting structure of the present invention as described above, both the attachment of the connecting fitting 10 to the horizontal frame 6 and the connection of the connecting fitting and the roller frame are simply push-fitted without using any bolts, screws, etc. In addition, the connecting fitting 1 connects the roller frame 1 and the horizontal frame 6.
0 is fitted and attached to the horizontal frame 6 by sandwiching the support edge 7 of the horizontal frame 6 between the mounting piece 13 and the bent piece 15, and also has an upward protrusion 16 formed on the bent piece 15 or at the tip of the mounting piece 13. The formed connecting piece 18 is fitted and latched into the connecting hole 8 of the horizontal frame support edge 7,
The bent portion 15' of the bent piece 15 is brought into contact with the front edge of the support edge 7, and in addition, in the case of the embodiment shown in FIG. Since the mounting bracket 10 is brought into contact with the edge, the mounting bracket 10 can be installed reliably and firmly.Moreover, the roller frame 1 is fitted into the vertical piece 11 of the connecting bracket 10, and the opening edge 2 is inserted into the notch 12 of the vertical piece. In the case of the example shown in FIG. 2, the connecting fittings 10 and the roller frame 1 are connected by fitting and latching, and in the case of the example shown in FIG. This also makes it possible to increase the mounting strength of the roller frame.
