Description

[Detailed explanation of the invention] This invention has a long and narrow board that hangs over the bottom of the bottom frame of the vaulting box, so it is stable when installed, and the long and thin board can be turned over and equipped with casters, so when transporting it, The casters are grounded and easy to transport, that is, the recesses 3 and 2 are provided in the opposite side plates 2 and 2 of the lowermost frame 1a, respectively.
3, and elongated plates 4, 4 that can be fitted into the recess 3°3.
is hung over the side plates 2, 2, and each elongated plate 4 is provided so as to be reversible in the range from the recess 3 to the lower end surface 2b of the side plate 2 via a pin 5, and casters 6.6 are attached to the upper surface of each elongated plate 4. It is characterized by:

In addition, the bottom tier frame 1a and the middle tier frames 1b, lb, 1b.
A triangular prism-shaped corner block 9 is provided protruding from each upper corner 8 of . reinforcing material 10 in contact with
are installed obliquely, and reinforcing members 11 are installed obliquely at each lower corner 8' of each middle step frame 1b and head frame 1C to form a triangular space 12, and the upper surface 10a of the reinforcing member 10 is and the downward surface 11a of the reinforcing material 11 is connected to the upper end surface 2a of the side plate 2, respectively.
If the triangular frame-shaped anti-slip 13 is installed on the same plane as the lower end surface 2b, and on each lower corner 8' and the lower direction 11a of the reinforcing member 11, each membrane frame itself will become strong. Of course, when multiple membrane frames are stacked, the lower corner pieces are inserted into the upper space, so the vaulting box does not collapse or wobble, and combined with the anti-slip effect, it is extremely stable. be.

Conventional vaulting boxes have problems in terms of stability when stacked in multiple tiers, and each membrane frame must be disassembled and transported, and then stacked, making moving work extremely troublesome.

There are several other conventional models that have casters, but all of them are difficult to control and have poor stability.

This invention solves these inconveniences. Next, the structure of one specific example will be explained in detail. A pair of grooves 3, 3 are cut out; on the other hand, elongated plates 4, 4 having a width and thickness approximately equal to the length and depth of the groove 3, and longer than the distance l between the side plates 2, 2; casters 6.6 are attached to the upper surface of both ends of each elongated plate 4, each elongated plate 4 is attached reversibly to the lower end surface 2b by a hinge 5',
Moreover, the range of rotation by the hinge 5' is as shown in the figure.
It extends from the position where the upper surface abuts the lower end surface 2b to the position where the lower surface of the elongated plate 4 abuts the ceiling surface 3a of the groove 3.

Next, to explain how to use this example of the invention, when installing the vaulting box A stacked in multiple tiers, the lower surface of each elongated plate 4 is in contact with the ground as shown by the solid line in Figures 1 to 4 and the chain line in Figure 5, and the casters are 6.6 is upside down.

Therefore, the vaulting exercise is performed in this state.

Next, in order to move the vaulting box A, first insert your fingers into the hand holes 7, 7 of the side plate 2', lift it slightly and turn each elongated plate 4 inward around the pin 5 of the hinge 5'. Move and flip.

As shown by the chain lines in Figures 1 and 2 and the solid line in Figure 5, each elongated plate 4 fits into the groove 3, and each caster 6 is in contact with the ground, and in this state the vaulting box A is pushed. It is.

Furthermore, at the storage location, each elongated plate 4 is turned over and the lower surface of the elongated plate 4 is grounded again.

Since this device has the above-mentioned structure, when using the vaulting box or storing it, the bottom surface of the elongated board that is hung between the opposing side panels is completely in contact with the ground, providing extremely good stability.Also, when transporting the vaulting box, the elongated board can be reversed. The casters touch the ground with the simple operation of just pressing the button, making it possible to move very easily and quickly.Furthermore, since the elongated plate fits into the groove, it can be transported reliably without rattling. .

[Brief explanation of drawings]

The figures show an example of this invention. Fig. 1 is a partially cutaway front view, Fig. 2 is a side view, Fig. 3 is a partially cutaway plan view, Fig. 4 is a bottom view, and Fig. 5 is a partially cutaway front view. The figure is an enlarged front view of the main part with a part cut away, and FIG. 6 is a perspective view showing the corner of the membrane frame.
