Abstract

PURPOSE:To provide vaulting box frame members, which are vertically stacked to each other stepwise, simply and easily carried for storing or using and do not occupy spaces for storing. CONSTITUTION:This vaulting box 1 is separably constructed by vertically stacking plural frame members 2, 3, 4 stepwise. A middle frame member 3 is made possible to be stored in a bottom frame member 2 vertically neighboring, and a top frame member 4 in the middle frame member 3 orderly. The top face of the top frame member 4 is formed with a mat member 5. The front part 51, about 1/3 portions, in the front rear direction of the mat member 5 is colored differently from the rear part 52 and hand marks 53 are marked in the front part 51 area.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple jump box used as a physical education tool for, for example, kindergarten children, and particularly to a storage place for each frame member which is vertically stacked in stages and assembled. In addition to saving space, it can be easily and easily carried during storage or use.

[0002]

2. Description of the Related Art Conventionally, in a jump box of this type, a plurality of frame members are vertically stacked so that they can be separated from each other stepwise, and the upper end surface of the uppermost frame member is formed of a mat member. It has an assembled structure.

In such a conventional jump box, for example, each frame member is stored in a tool room or the like in a separated state or a completely assembled state, and at the time of use, each frame member is individually separated by a plurality of hands. In the state, it is carried to the indoor or outdoor playground, the lowermost frame member is installed on the floor or on the ground, and the upper frame members adjacent to each other are sequentially stacked on the lowermost frame member to assemble, or Carried in a fully assembled state.

[0004]

However, in the above-mentioned vaulting box having the conventional structure, when storing each frame member in a tool room or the like, each frame member is individually separated or completely assembled. Since it is currently stored as a storage space, a large space is required in the storage location.

In addition, since each frame member is carried in the state of being separated or completely assembled at the time of storage or use, there is a problem that carrying is very troublesome.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to reduce the storage space of the frame members which are stacked one on top of the other and assembled, and to carry each frame member during storage or use. It is to provide a jump box that can be carried out simply and easily.

[0007]

In order to solve the above-mentioned problems, the present invention is constructed by stacking a plurality of frame members on top of each other in a stepwise manner and assembling the frame members at the uppermost stage. In a jump box formed of a mat member, the upper frame members can be sequentially housed in the lower frame members that are vertically adjacent to each other.

[0008]

That is, according to the present invention, by adopting the above-described structure, the upper frame members can be sequentially housed in the lower frame members which are vertically adjacent to each other. It is compactly incorporated and stored, which saves space in the storage space and is easy and easy to carry.

In addition, about 1/3 of the front side of the mat member in the front-rear direction is colored differently from the rear side and is colored, and a bill is provided on the front side. When teaching how to jump to kindergarten children, the coloring range and the bill on the front side of the mat serve as a guide for the landing position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described in detail with reference to the drawings. As shown in FIGS. 1 and 2, reference numeral 1 in the drawings represents a jump box according to the present invention. Is composed of, for example, three stages of frame members 2, 3 and 4 which are vertically stacked so as to be sequentially separable from each other.

The frame members 2, 3 and 4 constituting the jump box 1 are framed in a rectangular shape in a plane, and the frame member 3 in the middle stage is stacked on the frame member 2 in the lowest stage, and The uppermost frame member 4 has an assembled structure in which the uppermost frame member 4 is stacked on the middle frame member 3, and the upper end surface of the uppermost frame member 4 is made of, for example, a polymer of ethylene / vinyl acetate / acetate (E
A mat member 5 as a cushion body made of a foamed material such as VA) is separately provided, and the mat member 5 has a longitudinal width in the front / rear direction 1/3 range of the front part 51 side which is a rear part 52.
It is colored so as to be distinguished from the range on the side different from each other, and a bill 53 is provided in the range on the front part 51 side.

Further, both frame portions 21, 21, 31, 31, 31 and 4 facing each other in the lateral width direction of the frame members 2, 3, 4 respectively.
As shown in FIG. 3, 1 and 41 are inclined at a desired angle θ so as to have an isosceles trapezoidal shape, and the inclination angle θ
Is the outer spacing widths W1-1 and W2-1 between the upper end surfaces of the frame members 2 and 3 for the heights H1, H2 and H3, respectively.
Is the same as the outer spacing widths W2-1 and W3-2 between the lower end surfaces of the frame members 3 and 4 which are vertically adjacent to each other (W1-1 =
W2-2, W2-1 = W3-2), and the outer surfaces thereof are tilted flush and stacked.

Further, the inner spacing widths W1-3 and W2-3 between the lower end surfaces of the frame members 2 and 3 are determined by the respective frame members 3 and 3.
It is set to be larger than the outer gap width W2-1 and W3-1 between the upper end faces of 4 (W1-3> W2-1, W2-3> W
3-1), whereby the middle frame member 3 can be housed in the lowermost frame member 2, and the uppermost frame member 4 can be housed in the middle frame member 3 in order.

On the other hand, both frame portions 22, 22, 32, 32 and 4 facing each other in the vertical width direction of the frame members 2, 3 and 4 respectively.
2, 42, at least the plate thickness dimension t, as shown in FIG.
The frame portions 22, 22, 32, 32 and 42, 42 have a structure in which they are stacked in a staircase-like fitted state with a step difference of 1, t2, t3 or more.
Includes a pair of left and right holes 23, 23, 33, 3 which will be grips.
3 and 43, 43 are provided respectively.

In the figure, reference numerals 24 and 34 denote the frame members 2 and 3 respectively.
The recesses provided on the upper end surface of the
The dowel 3 provided on the lower end surface of each of the frame members 3 and 4.
5 and 45 are engaged with each other in the assembled state, whereby the positional displacement of the frame members 2, 3 and 4 can be prevented.

Further, in the figure, reference numerals 26, 36 and 46 denote frame portions 21 and 3 which face each other in the lateral width direction of the frame members 2, 3 and 4, respectively.
The reinforcing members are provided between 1 and 41, respectively.

That is, as shown in FIGS. 5 and 6, each of the frame members 2, 3 and 4 constituting the jump box 1 is the lowermost frame member 2 vertically adjacent to each other when stored or carried. The middle-stage frame member 3 is housed therein, and the upper-stage frame member 4 is housed in the middle-stage frame member 3 in the inverted state.

Incidentally, in the above embodiment, the jump box 1
Although the shape of is described as an example of a truncated pyramid shape, the shape is not limited to this, and other shapes include a truncated cone shape, and its selection is arbitrary,
Further, the number of steps of the jump box 1 is not limited to three, and may be, for example, five.
More than a step is possible.

[0019]

As is apparent from the above description, according to the present invention, the upper frame members can be sequentially housed in the lower frame members which are vertically adjacent to each other. It can be compactly incorporated and stored, which can save space in a storage place and can be easily and easily carried.

Further, about 1/3 of the front side of the mat member in the front-rear direction is colored differently from the rear side and is colored, and a bill is provided on the front side. Therefore, the coloring range and the handprint on the front side of the mat when teaching how to jump to a kindergarten child can be used as a guide for the wearing position, thereby improving the skill.
