The four corners of the underframe A are cut out so that the lower oblique sides 2' of the respective corner pieces 2 of the upper frame A come into contact with each other to form engaging edges 6'.

BACKGROUND OF THE INVENTION Conventionally, for example, an underframe with a top plate has been used for exercise equipment in which exercise members such as balance beams, ladders, slides, etc. are attached using stacked underframes as supports. However, in the conventional underframe with a top plate, the top plate is completely attached to the upper edge of the side plate, and there is no effective locking means, and the frames are extremely unstable when stacked.

This invention solves these inconveniences. Next, the structure of an embodiment of this invention will be explained in detail. The underframe A in this embodiment has a top plate 6 fixed to a side plate 1. Moreover, the side plate 1 is composed of front and rear side plates 1', 1', left and right side plates 1'', 1'', and more specifically, the lower edges of the left and right side plates 1'', 1'' are connected to the front and rear side plates 1', 1'. formed longer by a distance h,
Triangular prism-shaped corner pieces 2, 2, 2, 2 into the four corners of the underframe A
and fix the lower surface of each corner block 2 to the left and right side plates 1"
The lower end of the corner bar 2 is placed at the same height as the lower surface, that is, the lower end of the corner bar 2 protrudes from the lower end of the front and rear side plates 1', and the corner bar 2,
The elongated plate 3 is fixed and hung over the upper surface of the elongated plate 2, and the upper surface of the elongated plate 3 is placed at the same height as the upper surface of the side plate 1. A groove 4 is notched in the center outward edge of the elongated plate 3, and each side plate 1', 1', 1'', 1'' from the upper ends of the third, one or more pairs of engagement holes 5, 5 with a predetermined interval l.
A notch is formed in an inverted L-shape as shown in Figure 4, and the top plate 6 is fixed to the upper edges of the front and rear side plates 1', 1' and to the elongated plates 3, 3 to shield the underframe A. Sumiki 2 on the four corners
In order to match the shape of the end face of the left and right side plates 1'', the engaging edges 6' are formed by notching as shown in Figure 5.
1" and the lower surface of the corner bars 2, 2. In addition, B in the figure is a moving member used in this embodiment, and specifically, a pair of tilting L
The L-shaped metal fittings 8, 8 are manufactured, and each inverted L-shaped metal fitting 8 is attached to the end face of a movement member B, such as a balance beam, facing outward and horizontally as shown in the first figure.

Next, to explain how to use this embodiment, the middle underframe A is stacked on the lower underframe A. At this time, the rubber plates 7, 7 of the middle underframe A are brought into contact with the upper end surfaces of the left and right side plates 1'', 1'' of the lower underframe A and the triangular exposed portions 3', 3' of the elongated plates 3, 3. . Here, as shown in Fig. 5, the lower end oblique side 2' of each corner block 2 engages with the oblique engagement edge 6' of the top plate 6, and the stacked underframes A, A are separated from each other in the front and back and left and right directions. Engage without any problem.
Moreover, the lower edges of the left and right side plates 1'', 1'' of the middle underframe A abut on the left and right edges 6'', 6'' of the top plate 6, and are engaged more reliably. Similarly, the upper underframe A is stacked on the middle underframe A.

To explain the case of attaching the above-mentioned moving member B to the embodiments stacked in this way, first, as shown in the sixth figure, a pair of stacked underframes A' are
Face each other. Next, attach each outward horizontal portion 8' of the locking fittings 8, 8 of the balance beam, which is the moving member B, to the upper frame A.
3, as shown by the dashed lines in FIG. 8". Here, each outward horizontal portion 8' is locked to the inward surface of the side plate 1' as shown in the first figure.
There is no danger of it falling out, and in the same way, connect the locking metal fittings 8, 8 to the other stacked underframe A'.
The balance beam is installed as shown in Figure 6.

In the embodiment, the upper ends of the engagement holes 5, 5 cut into the left and right side plates 1'', 1'' are not covered by the top plate 6. This is to achieve the effect of engagement between the lower edges of the left and right side plates 1'', 1'' and the left and right side plates 6'', 6'' of the top plate 6. Furthermore, the groove 4 was cut out in the elongated plate 3 because the locking fittings 8 and 5 were inserted into the engagement holes 5, 5 of the left and right side plates 1''
8 can be locked without difficulty.

Next, the effects of this idea will be explained.

This idea consists of a vaulting box underframe in which front and rear side plates and left and right side plates form side plates, and a top plate is fixed to the side plates. Triangular prism-shaped corner pieces are fixed to the four corners of the underframe, and each corner piece is made to protrude from the front and rear side plates. , the four corners of the top plate are cut out so that the lower end oblique sides of each corner corner of the underframe located on the upper level are attached to form an engaging edge, so it is extremely important to attach the lower end oblique side of the corner wood to the engaging edge of the top plate. The underframes can be stacked quickly and reliably with easy work, and there is no risk of the underframes coming off front to back or left to right, providing good stability. Since it is only necessary to form it so that it is attached, it can be manufactured reliably and easily. In addition, the lower edges of the left and right side plates are made longer than the front and rear side plates by the thickness of the top plate, and the upper edges of the front and rear side plates and the left and right side plates are at the same height. The lower edge of the left and right side plates of the top plate and the lower edges of the left and right side plates of the underframe located in the upper row are engaged with each other. Due to the engagement between the top plate and the top plate, the engagement distance is extremely long, the stability is further increased, there is no rattling during use, and it is extremely durable and safe.

Next, the effects of an embodiment of this invention will be explained.

Attaching rubber plates to the left and right side plates and to the lower surfaces of the corner blocks as in the embodiment provides an effective anti-slip effect when the underframes are stacked or when the underframes are used alone. Further, as in the embodiment, a pair of engagement holes having a predetermined interval are notched in the side plate in an inverted L shape, and a pair of locking fittings that can be freely engaged and detached from the engagement holes are cut out in an inverted L shape. If a movement member such as a balance beam is equipped with this locking metal fitting horizontally attached, the connection can be made by simply inserting the locking metal fitting and dropping it, and if this device is used as the above-mentioned exercise tool, Assembly and disassembly can be made easy and quick, and if the top plate is fixed so as to cover the upper end of the engagement hole, when used as the above-mentioned exercise tool,
Unlike conventional products, it does not wobble even when force is applied in the vertical direction during use, and has great stability.
There is no risk of the locking metal fittings coming off, and there is no need to drill holes into the top plate, so it is strong and safe to use with no risk of pinching your fingers.It also has a good appearance and has a pair of locking devices. It can be nailed into the holes at predetermined intervals (indicated by the X marks in Figure 1), and the top plate and side plates can be secured in a good manner.
