Description

The present invention relates to a vaulting box that transforms into, for example, a bed for infants.

A vaulting box is exercise equipment used, for example, in a school physical education class. A general vaulting box has a trapezoidal shape when viewed from the lateral direction (front view and rear view), a rectangular shape when viewed from the longitudinal direction, and a rectangular shape when viewed from above. The vaulting box has a configuration in which a plurality of corrugated boxes are vertically stacked so that the height can be adjusted. Vaulting boxes used in school education such as elementary schools include a small one with 6 steps and a large one with 8 steps.

By the way, for example, local schools such as elementary and junior high schools are often used as evacuation centers when disasters such as earthquakes and typhoons occur. Gymnasiums, in particular, accept many evacuees and provide a place for indoor evacuation life. However, many exercise equipments do not help in evacuation life, and are stored in, for example, physical education warehouses, and vaulting boxes are no exception.

It is a perspective view of the bed for infants formed by changing the shape of the vaulting box. Figure 3 is a perspective view of a hammock member of the infant bed; FIG. 4 is a vertical cross-sectional view of the vaulting box and the infant bed, and a six-sided view of a fixing corner. It is a figure explaining the procedure which changes the form of the said vaulting box to a bed for infants.

A vaulting box according to a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. However, the technical scope of the present invention is not construed to be limited by the embodiments described below.

(Form of vaulting box)
FIG. 1 is a perspective view of a vaulting box 1 of this embodiment. The vaulting box 1 is constructed by stacking a plurality of corrugated boxes 10 to 14 vertically in a mountain shape. The vaulting box 1 has a trapezoidal shape that widens from the top tier box 10 to the bottom tier box 14 when viewed from the side (that is, viewed from the front and back) in the short direction. On the other hand, both the side view in the longitudinal direction and the plan view from above are rectangular. Although the size is not limited, for example, a trapezoid with a base of 795 mm × upper side of 330 mm × height of 1000 mm when viewed from the front in the short direction, a rectangle with a length of 800 mm × height of 1000 mm when viewed from the side in the longitudinal direction, It is a rectangle with a width of 795 mm and a length of 800 mm when viewed from above.

The corrugated boxes 10 to 14 constituting the vaulting box 1 are rectangular frames in which plate materials (horizontal plates in the longitudinal direction and end plates in the lateral direction) are arranged on the four sides and fixed at the four corners. It's hollow. However, an intermediate reinforcing member for reinforcement may be provided. A protective end piece 15 such as rubber is arranged on the bottom surface of the corrugated boxes 10 to 14, and the corrugated boxes 10 to 14 are stacked with the protective end piece 15 interposed therebetween. The protective end tools 15 are arranged, for example, at the four corners of the bottom surface.

In particular, as shown in the cross-sectional view of FIG. 2, the corrugated box 12 on the third tier from the top is provided with fixing corners 2, for example, at the four corners as an example of convex fixing members protruding upward. Fixing corners 21 are provided at the four corners of the corrugated box 11 on the second tier and the corrugated boxes 13 to 14 on the fourth to fifth tiers, as an example of convex fixing members protruding upward. . As a result, the fixing corners 2 and 21 are engaged with the inner wall surfaces of the corrugated boxes 10 to 13 positioned on the upper tier, so that they do not shift during the vault exercise. In addition, although a general vaulting box is provided with a fixing corner 21 on each level of the corrugated box, in the present embodiment, the shape of the corrugated box 12 on the third level is different so that it can be transformed into a baby bed. A fixing corner 2 is provided. The shape of the fixing corners 2 and 21 will be described later.

As an example, the vaulting box 1 has a five-stage structure. However, the height of the frame of the middle box 11 located on the second level from the top is set higher than that of the boxes 12 to 14 below the third level so that the shape can be changed into an infant bed. there is As an example, the height of the boxes 12 to 14 on the third to fifth stages is 100 mm, and the height of the box 11 on the second stage is 400 mm. That is, the vaulting box 1 itself substantially has a height of 8 steps including the uppermost step box 10 . In other words, it is a configuration in which the 2nd to 5th tier boxes of the vaulting box, which normally has 8 tiers, are integrated. Of course, the height of each of the boxes 10 to 14 and/or the number of steps of the vaulting box 1 can be changed as appropriate.

The uppermost corrugated box 10 has a top plate 10a on its upper surface, on which a cushioning material 10b for safety is arranged. The cushioning material 10b is, for example, urethane. Then, the covering 10c is arranged so as to cover the cushioning material 10b, and is fixed to the main body of the corrugated box 10 with a plurality of pins 10d arranged along the edge of the covering 10c. As a result, a mat portion is formed on the upper surface of the corrugated box 10 . Upholstery 10c is typically a single piece of cloth, leather, or the like. As an example, the height of the uppermost corrugated box 10 is 300 mm from the bottom surface to the upper surface of the cover 10c. The thickness of the cushioning material 10b is, for example, about 50 mm.

When transporting the vaulting box 1 or adjusting the height, the boxes 12 to 14 on the third to fifth stages have lateral and A hand groove 16 is formed in each of the longitudinal side bottoms. On the other hand, the corrugated box 11 of the second tier is formed with a set of two handling holes 17 on the side surface. A pair of hand-holding holes 17 are formed in both the lateral and longitudinal sides. A set of two handholding holes 17 is formed in the lateral side surface of the uppermost corrugated box 10.例文帳に追加

A preferred example of the vaulting box 1 is made of wood. For the wood, for example, lauan is used. However, the vaulting box 1 is not limited to being made of wood, and may be made of other materials. The same applies to the fixing member.

(Form of infant bed)
FIG. 3 is a perspective view of an infant bed in which the vaulting box 1 is modified (referred to as an "infant bed 3" for convenience of explanation). In the infant bed 3, the uppermost corrugated box 10 is removed, the second corrugated box 11 is turned upside down and stacked on the third corrugated box 12.例文帳に追加Although illustration is omitted, the uppermost corrugated box 10 having a mat portion on the upper surface can be used as a chair on which a parent of an infant sits, for example, by placing it nearby.

The portion of the bed on which the infant is placed is configured by attaching a hammock member 31 made of cloth, for example, to the body portion 31a. The hammock member 31 is arranged so as to cover the upper opening of the upside down second-tier corrugated box 11, and is fixed to one of the corrugated boxes 11 to 14 by a plurality of cloth bands 32 (32a, 32b), for example. do. In FIG. 3, as an example, the hammock member 31 is fixed by spanning the band 32 (32a, 32b) over the handle groove 16 of the corrugated box 12 on the third stage. By stretching the band 32 (32a, 32b) in this way, the whole is fixed and the sense of stability is improved. However, the place where the band 32 (32a, 32b) is spanned may be changed as appropriate. The body portion 31a of the hammock member 31 is preferably made of cloth, but may be made of other materials. The band 32 is also the same.

The hammock member 31, as particularly shown in FIG. 4, has a box-like main body 31a having, for example, a bottom surface and four side surfaces. The shape may be changed as appropriate. The cloth on the longitudinal side is made long so as to cover the outer side of the corrugated box 11 (see FIG. 3). Preferably, the plurality of bands 32 (32a, 32b) include a band 32a that spans the corrugated boxes 11 in the vertical direction and a band 32b that spans the corrugated boxes 11 in the lateral direction. A band 32a extending from the bottom surface of the main body portion 31a and a band 32a-2 extending from the upper side of the main body portion 31a are detachable by connecting members 33 of the band 32a extending over the corrugated boxes 11 in the vertical direction. The connection member 33 is, for example, a side release buckle. Similarly, a band 32b extending along the width direction of the corrugated box 11 can be attached and detached by a connecting member 33. As shown in FIG. In FIG. 4, the bands to be connected are connected by arrows. The band 32a-1 arranged on the bottom surface side is preferably a reinforcing member for the body portion 31a by sewing a single band extending in the longitudinal direction and the width direction to the bottom surface of the body portion 31a. Although not shown, each band 32 (32a, 32b) is adjustable in length. The length adjusting means is, for example, a single pull buckle with a length adjusting function on one side. Of course, other buckles and other length adjusting means may be used.

Next, the shapes of the fixing corners 2 and 21 will be described in detail with reference to FIG. FIG. 5 shows a longitudinal sectional view of the vaulting box 1 and the infant bed 3, as well as six views of the fixing corners 2 and 21. As shown in FIG. As shown in FIG. 5, the fixing corners 21 provided on the corrugated boxes 11, 13, 14 except for the third corrugated boxes are, for example, wooden pieces having a triangular horizontal cross section. The fixing corner 21 has a side surface 21a that is an inclined surface and a side surface 21b that is a vertical surface. The longitudinal inclined inner wall surface and the transverse vertical inner wall surface are engaged with each other.

On the other hand, the fixing corners 2 provided in the third row of boxes 12 are, for example, pieces of wood having a square horizontal cross section. The fixing corner 2 has an inclined side surface 2a, a vertical side surface 2b, and an inclined side surface 2c. When the second corrugated boxes 11 are stacked in a normal posture for use as the vaulting box 1, the side surfaces 2a and 2b of the corrugated boxes 11 are inclined in the longitudinal direction and vertical inner wall surfaces in the lateral direction. respectively. On the other hand, when the corrugated boxes 11 on the second level are turned upside down and stacked for use as the infant bed 3, the side surface 2c engages with the inclined outer wall surface of the corrugated boxes 11 in the longitudinal direction. As a result, positional deviation can be prevented in any form.

The side surfaces 2a to 2c are examples of support portions. That is, the example of FIG. 5 shows a configuration in which the fixing corners 2, 21 and the side surfaces of the corrugated boxes 10 to 13 are in surface contact to fix the position. It is good also as a shape which makes point contact.

An example of the procedure for changing the configuration shown in FIG. 1 to the configuration shown in FIG. 2 will be described.
For example, when a disaster or the like occurs and the school becomes an evacuation center, the vaulting box 1 and the hammock member 31 are removed from, for example, the physical education warehouse and placed in the gymnasium. Then, the uppermost corrugated box 10 is removed, and the second corrugated box 11 is lifted using the lateral and/or longitudinal hand holes 17 and turned upside down as shown in FIG. Then, it is stacked on top of the corrugated box 12 on the third level. At this time, the side surface 2c, which is the support surface of the fixing corner 2, is engaged with the inclined outer wall surface of the corrugated box 11 in the longitudinal direction and fixed. Subsequently, the hammock member 31 is positioned at the upper opening of the corrugated box 11 .

At this time, the band 32a-1 on the bottom side passes through the insides of the corrugated boxes 11 and 12 and is brought out through the notch 16 of the corrugated box 12 to the outer wall side. On the other hand, the band 32a-2 on the upper side of the side edge spans from the outer wall side of the corrugated boxes 11 and 12 and is connected with the band 32a-1 on the bottom side by the connecting member 33. As shown in FIG. The same applies to the lateral direction and the longitudinal direction. After that, the band 32b is stretched over the corrugated box 11 along the lateral direction and connected by the connecting member 33.例文帳に追加If the band is loose, adjust the length of the band accordingly. Through this series of procedures, the vaulting box 1 of FIG. 1 is transformed into the infant bed 3 of FIG. Conversely, when changing the form from the infant bed 3 to the vaulting box 1, the procedure can be reversed.

According to the above-described embodiment, the uppermost corrugated box 10 is removed, the corrugated box 11 is turned upside down and stacked on and engaged with the lower corrugated box 12, and the hammock member 31 is placed in the upper opening of the corrugated box 11. , the vaulting box 1 can be transformed into a bed 3 for infants. As a result, for example, in an evacuation shelter, the vaulting box 1 can be used as a bed 3 for infants, which can help parents with small children in evacuation life.

In the above-described embodiment, in the case of a normal vaulting box, the corrugated boxes corresponding to the second to fifth tiers are integrated and turned upside down, but the corrugated boxes to be integrated are not limited to this. For example, in the case of a normal vaulting box, the 3rd to 6th corrugated boxes are integrated and turned upside down, or the 2nd to 4th corrugated boxes are unified and turned upside down. be able to. In other words, there is no limitation as to what row the middle row of boxes to be turned upside down is on. And it can be used as a normal vaulting box even if any of the steps are put together. Although the integrated corrugated box is heavy, it has the advantage that it can be transported collectively and can be transported by a plurality of people, so that it can be transported more safely than by one person. In addition to manufacturing and selling the entire vaulting box 1, it is also possible to replace the integrated corrugated box portion with the corrugated box of an existing normal vaulting box. It should be noted that the attachment of the hammock member 31 is preferably of the assembly type described above, but it is not excluded that the hammock member 31 is always fixed to the corrugated box 11 .

Although the present invention has been described in detail with reference to specific embodiments, various substitutions, modifications, changes, etc. in terms of form and details may be made within the scope of the present invention as defined by the scope of the claims. It will be clear to those of ordinary skill in the art that things can be done without departing from the spirit and scope.
