Description

[Technical field]

[0001] The present invention relates to a vaulting horse that can be transformed into, for example, a child bed. [Background technology]

[0002] A vaulting box is a piece of exercise equipment used in, for example, school physical education classes. A typical vaulting box is trapezoidal when viewed from the short side (front and back), rectangular when viewed from the long side, and rectangular when viewed from above. A vaulting box is made up of multiple boxes stacked on top of each other so that the height can be adjusted. Vaulting boxes used in school education at elementary schools and other institutions come in small sizes with six steps and large sizes with eight steps.

[0003] By the way, local schools, such as elementary and junior high schools, are often used as evacuation shelters when disasters such as earthquakes and typhoons occur. Gymnasiums in particular accommodate many evacuees and provide a place for them to live indoors. However, most sports equipment is not used to help with evacuation life and remains stored in, for example, gym storage rooms, and vaulting boxes are no exception.

[0005] The present invention has been made based on the above circumstances, and the problem to be solved is to provide a vaulting box that can be transformed into a bed for a child, for example, when a school or other place is used as an evacuation shelter in the event of a disaster. [Means for solving the problem]

[0006] That is, the gist of the present invention is as follows. (1) The vaulting box of the present invention is constructed by stacking a number of trapezoidal tiered boxes one on top of the other when viewed from the front, and is characterized in that the top tiered box having a mat portion on its upper surface is removed, and the middle tiered box is inverted upside down and engaged on top of the lower tiered box, and a hammock member is attached to the upper opening of this middle tiered box, making it possible to transform it into a baby bed. (2) The middle box to be inverted is characterized in that the frame height is higher than that of the other boxes. (3) A corrugated box located below the middle corrugated box is provided with a convex fixing member at a corner thereof, and the fixing member is characterized in that it has both a support portion that engages with an inner wall surface of the corrugated box when the middle corrugated box is stacked in the normal position, and another support portion that engages with an outer wall surface of the corrugated box when the middle corrugated box is stacked upside down. Effect of the Invention

[0007] According to the present invention, the vaulting box can be transformed into a baby bed by removing the top box of the vaulting box, inverting the middle box and fitting it on top of the bottom box, and attaching a hammock member to the upper opening of the middle box. As a result, for example, in a disaster evacuation shelter, the vaulting box can be used as a baby bed, making it possible to help parents with small children during evacuation.

[0009] Hereinafter, a vaulting box according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the technical scope of the present invention is not limited to the following embodiments.

[0010] (Vaulting horse shape) FIG. 1 is a perspective view of a vaulting box 1 of this embodiment. The vaulting box 1 is configured by stacking multiple tiered boxes 10 to 14 in a mountain shape in the vertical direction. The appearance of the vaulting box 1 is a trapezoidal shape that widens from the top tiered box 10 to the bottom tiered box 14 when viewed from the side in the short side direction (i.e., when viewed from the front and the back). On the other hand, both the side view in the long side direction and the plan view from above are rectangular. The size is not limited, but as an example, the front view in the short side direction is a trapezoid with a base of 795 mm, a top of 330 mm, and a height of 1000 mm, the side view in the long side direction is a rectangle with a length of 800 mm and a height of 1000 mm, and the plan view is a rectangle with a width of 795 mm and a length of 800 mm.

[0011] The boxes 10-14 that make up the vaulting box 1 are rectangular frames with plate materials (horizontal boards in the long direction and end boards in the short direction) arranged on all four sides and fixed at the four corners, and are hollow inside to reduce weight. However, intermediate reinforcing materials may be provided for reinforcement. Protective end fittings 15, for example made of rubber, are arranged on the bottom surfaces of the boxes 10-14, and the boxes 10-14 are stacked together via these protective end fittings 15. The protective end fittings 15 are arranged, for example, on the four corners of the bottom surface.

[0012] As shown in the cross-sectional view of FIG. 2, the third box 12 from the top is provided with fixing corner pieces 2 at, for example, the four corners as an example of a fixing member with a convex shape protruding upward. The second box 11 and the fourth and fifth boxes 13-14 are provided with fixing corner pieces 21 at, for example, the four corners as an example of a fixing member with a convex shape protruding upward. As a result, the fixing corner pieces 2, 21 engage with the inner wall surface of the box 10-13 located at the upper level, so that they do not shift position when performing vaulting box exercise. Note that a general vaulting box is provided with fixing corner pieces 21 at each box level, but in this embodiment, the third box 12 is provided with fixing corner pieces 2 with a different shape so that it can be transformed into a baby bed. The shapes of the fixing corner pieces 2, 21 will be described later.

[0013] As an example, the vaulting box 1 has five levels. However, the frame height of the middle step box 11, which is the second step from the top, is set higher than the step boxes 12 to 14 below the third step, so that it can be transformed into a baby bed. As an example, the heights of the third to fifth step boxes 12 to 14 are 100 mm, and the height of the second step box 11 is 400 mm. That is, the vaulting box 1 itself has a height equivalent to eight steps, including the top step box 10. In other words, the second to fifth steps of a vaulting box that is normally eight steps are integrated into one. Of course, the heights of the step boxes 10 to 14 and / or the number of steps of the vaulting box 1 can be changed as appropriate.

[0014] The topmost box 10 has a top plate 10a on its top surface, on which safety cushioning material 10b is placed. The cushioning material 10b is, for example, urethane. Then, a top layer 10c is placed to cover the cushioning material 10b, and is fixed to the body of the box 10 with multiple pins 10d placed along the edge of the top layer 10c. This forms a mat on the top surface of the box 10. The top layer 10c is generally a single piece of cloth or leather. As an example, the height of the topmost box 10 is 300 mm from the bottom surface to the top surface of the top layer 10c. The thickness of the cushioning material 10b is, for example, about 50 mm.

[0015] To enable the vaulting box 1 to be lifted one level at a time or several levels at a time when transporting or adjusting its height, the third to fifth tiered boxes 12-14 are each formed with a hand groove 16 on the bottom of the side in the short and long directions. Meanwhile, the second tiered box 11 has a pair of hand holes 17 formed on its side. The pair of hand holes 17 are formed on both the short and long side faces. The top tiered box 10 has a pair of hand holes 17 formed on its short side face.

[0016] A preferred example of the vaulting box 1 is made of wood. For example, lauan wood is used as the wood. However, the vaulting box 1 is not limited to being made of wood, and may be made of other materials. The same goes for the fixing members.

[0017] (Type of baby bed) Fig. 3 is a perspective view of an infant bed in which the vaulting box 1 has been modified (for ease of explanation, it will be referred to as "infant bed 3"). Infant bed 3 has the topmost box 10 removed, and the second box 11 turned upside down and stacked on top of the third box 12. The topmost box 10, which has a mat on its top surface, is not shown in the figure, but can be placed nearby and used as a chair for the parent of the infant to sit on, for example.

[0018] The bed portion on which the infant is placed is constructed by attaching a hammock member 31 having a main body 31a made of, for example, cloth. The hammock member 31 is arranged so as to cover the upper opening of the second-stage box 11 that is turned upside down, and is fixed to one of the stages 11 to 14 with a plurality of bands 32 (32a, 32b) made of, for example, cloth. In FIG. 3, as an example, the hammock member 31 is fixed by hanging the bands 32 (32a, 32b) over the handle groove 16 of the third-stage box 12. By hanging the bands 32 (32a, 32b) in this way, the whole is fixed and the sense of stability is improved. However, the place where the bands 32 (32a, 32b) are hung may be changed as appropriate. The main body 31a of the hammock member 31 is preferably made of cloth, but may be made of other materials. The same applies to the bands 32.

[0019] As shown in FIG. 4, the hammock member 31 has a main body 31a in the shape of a box having a bottom and four side surfaces. The shape may be changed as appropriate. The fabric of the side surface in the longitudinal direction is long enough to span the outer side surface of the corrugated box 11 (see FIG. 3). The multiple bands 32 (32a, 32b) preferably include a band 32a that is stretched across the corrugated box 11 in the vertical direction and a band 32b that is stretched across the corrugated box 11 in the lateral direction. The band 32a that is stretched across the corrugated box 11 in the vertical direction is made detachable by a connecting member 33, with a band 32a-1 extending from the bottom surface of the main body 31a and a band 32a-2 extending from the upper edge of the side surface. The connecting member 33 is, for example, a side release buckle. Similarly, the band 32b that is stretched across the corrugated box 11 in the lateral direction is made detachable by the connecting member 33. Note that in FIG. 4, the bands that are connected to each other are connected by arrows. The band 32a-1 arranged on the bottom side is preferably a single band extending in the longitudinal and lateral directions sewn to the bottom surface of the main body 31a to serve as a reinforcing member for the main body 31a. Although not shown in the drawings, each band 32 (32a, 32b) is made adjustable in length. The length adjustment means is, for example, a one-way pull buckle with a length adjustment function on one side. Of course, other buckles and other length adjustment means may also be used.

[0020] Next, the shape of the fixing corner bars 2, 21 will be described in detail with reference to Fig. 5. Fig. 5 shows a vertical cross-sectional view of the vaulting box 1 and the baby bed 3, as well as six-sided views of the fixing corner bars 2, 21. As shown in Fig. 5, the fixing corner bars 21 provided on the boxes 11, 13, 14 except for the third box are, for example, pieces of wood with triangular horizontal cross-sections. The fixing corner bar 21 has an inclined side surface 21a and a vertical side surface 21b, and when the boxes 10, 12, 13 are stacked, the side surfaces 21a and 21b engage with the inclined inner wall surface in the longitudinal direction and the vertical inner wall surface in the lateral direction of the boxes 10, 12, 13, respectively.

[0021] On the other hand, the fixing corner bar 2 provided on the third box 12 is, for example, a piece of wood with a rectangular horizontal cross section. The fixing corner bar 2 has a slanted side 2a, a vertical side 2b, and a slanted side 2c. When the second box 11 is stacked in the normal position to be used as the vaulting box 1, the side 2a and the side 2b engage with the slanted inner wall surface in the longitudinal direction and the vertical inner wall surface in the lateral direction of the box 11, respectively. On the other hand, when the second box 11 is stacked upside down to be used as the baby bed 3, the side 2c engages with the slanted outer wall surface in the longitudinal direction of the box 11. This makes it possible to prevent misalignment in either configuration.

[0022] The side surfaces 2a to 2c are an example of a support portion. That is, in the example of Fig. 5, the fixing corner bars 2, 21 and the side surfaces of the corrugated boxes 10 to 13 are in surface contact with each other to fix the positions, but this is not limited to surface contact, and may be a shape that makes line contact or point contact.

[0023] In the above configuration, an example of a procedure for changing the configuration from that shown in FIG. 1 to that shown in FIG. 2 will be described. For example, if a disaster occurs and a school becomes an evacuation shelter, the vaulting box 1 and hammock member 31 are removed from, for example, the gym storehouse and placed inside the gymnasium. Then, the topmost step box 10 is removed, and the second step box 11 is lifted up using the handle holes 17 in the short and / or long directions, and then turned upside down as shown in FIG. 6. It is then stacked on top of the third step box 12. At this time, the side surface 2c, which is the support surface of the fixing corner bar 2, engages with and is fixed to the longitu- dinal inclined outer wall surface of the step box 11. Next, the hammock member 31 is positioned at the upper opening of the step box 11.

[0024] At this time, the bottom band 32a-1 passes through the inside of the step boxes 11 and 12 and comes out to the outer wall side through the cutout 16 of the step box 12. On the other hand, the band 32a-2 on the upper side of the side edge is stretched from the outer wall side of the step boxes 11 and 12 and connected to the bottom band 32a-1 by the connecting member 33. The same applies to the short and long directions. After that, the band 32b is stretched along the short direction of the step box 11 and connected by the connecting member 33. If there is any slack in the band, adjust the length of the band as appropriate. This series of steps changes the shape from the vaulting box 1 in FIG. 1 to the baby bed 3 in FIG. 3. Conversely, when changing the shape from the baby bed 3 to the vaulting box 1, the steps can be reversed.

[0025] According to the above-mentioned embodiment, the topmost step box 10 is removed, step box 11 is turned upside down and stacked on and engaged with the lower step box 12, and the hammock member 31 is attached to the upper opening of step box 11, thereby making it possible to change the shape of the vaulting box 1 into a baby bed 3. As a result, for example, in an evacuation shelter, the vaulting box 1 can be used as a baby bed 3, which can help parents with small children during their evacuation.

[0026] In the above embodiment, the boxes that would be the second to fifth steps of a normal vaulting box are integrated and inverted upside down, but the boxes that are integrated are not limited to this. For example, the boxes that would be the third to sixth steps of a normal vaulting box can be integrated and inverted upside down, or the boxes that would be the second to fourth steps of a normal vaulting box can be integrated and inverted upside down. In other words, there is no limit to which step the middle step box that is inverted upside down is located. And even if any step is combined, it can be used as a normal vaulting box. Although the integrated step box is heavy, it has the advantage that it can be carried together and can be carried by multiple people, so it can be carried more safely than by one person. In addition, it is of course possible to manufacture and sell the entire vaulting box 1, and the integrated step box part may be replaced with the step box of an existing normal vaulting box. It is preferable to attach the hammock member 31 in the above-mentioned assembly type, but this does not exclude the case where it is permanently fixed to the step box 11.

[0027] Although the present invention has been described in detail with reference to specific embodiments, it will be apparent to those skilled in the art that various substitutions, modifications, changes, etc. in form and detail can be made therein without departing from the spirit and scope of the present invention as defined by the claims.
