  However, the foldable mattress described in the above-mentioned Patent Document 1 is composed of first to third mattresses (mat portions), and the three mattresses (mat portions) are connected at one place which is the same place. Therefore, when it is spread or folded repeatedly, there is a problem that the connecting portion weakens and the exterior fabric is torn or the first to third mattresses (mat portions) are easily separated.

  In addition, when the first to third mattresses (mat portions) are expanded to form a triangular cushion, the first mattress (mat portion) and the second mattress (mat portion) are arranged in the lowermost layer. Even if three mattresses (mat part) are used, the height is twice the thickness (height) of one mattress (mat part), so the problem is that it is not easy to use as a cushion. There is.

  Therefore, the present invention has been made to solve such problems, and even when three or more mat parts are expanded or folded at the connection part repeatedly, the connection part is not easily weakened. And when it folds in a connection part, it becomes the sum total of the thickness of several mat | matte parts, and it aims at providing the foldable mattress which can improve the usability as a cushion.

In order to solve the above problems, a foldable mattress according to the present invention is a foldable mattress in which three or more mat portions are connected to each other so as to be foldable at a connecting portion between adjacent mat portions. When the mat portion is widened, it becomes one plate-like mattress. On the other hand, when the plurality of mat portions are folded at the respective connecting portions, each step of the mat portion is composed of one mat portion, and the plurality of mat portions. It is characterized in that it is configured to have a substantially right-angled triangular cushion in a side view with three or more stages equal to the number of.
Further, in the folding mattress according to the present invention, when folded among the plurality of mat portions, the uppermost mat portion has a right-sided triangle and the second and subsequent steps other than the uppermost mat portion. The mat part of the uppermost mat part has the same thickness as the right triangle on the side of the uppermost mat part, and the side face is configured as a right trapezoid. The bottom of the triangle on the side of the uppermost mat part is the second step from the top. Same as the length of the upper base of the right trapezoid on the side of the mat part, and if there is a mat part on the third and subsequent stages from the top, the length of the upper base of the right trapezoid on the side of the mat part on and after the third stage Is the same as the length of the bottom of the right trapezoid on the side of the mat that is directly above, and the length of the bottom of the right trapezoid on the side is the right trapezoid on the side if there is a mat that is directly below The same as the length of the upper base, and the acute angle of the right trapezoid on the side surface of the mat part after the second stage, Serial at the same angle as one of acute right triangle sides of the mat portion of the uppermost overall side by folding a plurality of mat unit is to be characterized be a triangle.
Moreover, in the foldable mattress according to the present invention, the plurality of mat portions are constituted by four mat portions, and are separate from the plurality of mat portions and are the same as the plurality of mat portions. It is also characterized in that the side surfaces having the same thickness and width have a rectangular auxiliary mat.

The foldable mattress according to the present invention is a foldable foldable mattress in which three or more mat portions are connected to each other so that the mat portions can be folded at adjacent mat portions. On the other hand, when the plurality of mat portions are folded at the respective connecting portions, the mat portions at each step are configured by one mat portion, and the number of the plurality of mat portions It is configured so as to form a cushion having a substantially right-angled triangular shape in side view with the same three or more steps.
Therefore, even if three or more mat parts are spread or the folding at the connecting part is repeated, the connecting part is not one place, so that the connecting part is not easily weakened.
In addition, when folded at the connecting portion, the total thickness of the three or more steps equal to the number of the three or more mat portions, and the height is increased, so that the usability as a cushion can be improved. it can.

  Next, an embodiment of a folding mattress according to the present invention will be described with reference to the accompanying drawings. The embodiment described below is merely an example of the present invention, and the present invention is not limited to the embodiment described below, and can be appropriately changed within the scope of the technical idea of the present invention. is there.

  As shown in FIG. 1, the foldable mattress 1 of the embodiment is a foldable base mat in which four mat portions 11 to 14 having inclined surfaces are connected so as to be foldable by connecting portions between adjacent mat portions 11 to 14. 10 and an auxiliary mat 20 that is separated from the folding base mat 10 and is used as an auxiliary.

  The four mat portions 11 to 14 and the auxiliary mat 20 constituting the foldable base mat 10 each cover a cushion body formed of foamed resin such as urethane foam with a fabric made of fibers such as cotton or polyester. Configured. Therefore, the front fabric is provided with an insertion opening that can be opened and closed by a chuck (not shown) so that the cushion bodies constituting the four mat portions 11 to 14 and the auxiliary mat 20 can be individually inserted. In addition, a storage chamber partitioned on the front fabric of the foldable base mat 10 such that each boundary is sewn so that the cushion members constituting the four mat portions 11 to 14 are not moved. Is provided, and a boundary portion that is sewn or the like, that is, a boundary portion of each storage chamber serves as a connecting portion.

<Folding base mat 10>
The foldable base mat 10 has a plate-like mattress as shown in FIG. 2 when the four mat portions 11 to 14 in which the adjacent mat portions are connected to each other by the connecting portions are expanded. When the portions 11 to 14 are folded at the respective connecting portions, the mat portions 11 to 14 of each step are configured by one mat portion as shown in FIGS. 1 and 3 and the like, and the four mat portions 11 to 14 are formed. The cushion is configured in the same four steps as the number of cushions in the shape of a substantially right triangle when viewed from the side. However, since the four mat portions 11 to 14 are formed by covering a cushion body formed of a foamed resin such as a urethane format with a surface fabric, the corners are rounded at this point or a slight angle error occurs. is doing.

  Specifically, among the four mat portions 11 to 14, when folded, the uppermost mat portion 11 has a substantially right side triangle and the second to fourth steps other than the uppermost mat portion 11. The mat portions 12 to 14 as the steps are configured to have a right trapezoidal shape with the same thickness as the height of the right triangle on the side surface of the uppermost mat portion 11.

  That is, the four mat portions 11 to 14 have a thickness (height) of, for example, about 11.5 cm and a width of about 91 cm for a single bed, as shown in FIGS.

  When the side surface is folded so as to form a right triangle, the mat portion 11 which is the uppermost layer has a bottom length of about 20 cm. In addition, the internal angles of the right triangle on the side surface of the mat portion 11 are approximately 90 degrees, 30 degrees, and 60 degrees, respectively.

  When the side surface is folded so as to form a right triangle, the mat portion 12 that is the second step from the top has the mat portion 11 on it as shown in FIGS. As shown in FIG. 4, the length of the upper base is about 20 cm, the length of the lower base is 40 cm, and the mat portion 13 that is the third step from the top is placed with the mat portion 12 on top, so the length of the upper base is about 40 cm, the length of the lower base is 60 cm.

  When the side surface is folded so as to form a right triangle, the mat portion 14 in the lowermost layer in the fourth step from the top has the mat portion 13 on top as shown in FIGS. Is about 60 cm, and the length of the lower base is 80 cm.

  Therefore, when the foldable base mat 10 of the present embodiment, in which the four mat portions 11 to 14 are connected, is folded, as shown in FIG. The cushion becomes a substantially right triangle when viewed from the side with a length of 46 cm (11.5 cm × 4) cm, which is the same as the length of 80 cm and the height of the four mat portions 11 to 14. As shown in FIG. 3, the length of the inclined surface when it is folded into a substantially right triangle when viewed from the side is about 92 cm.

  On the other hand, although the mat part 11 and the mat part 12 are folded, when the folding base mat 10 of the present embodiment in which the four mat parts 11 to 14 are connected is expanded, the length is shown in FIG. Thus, the mattress has a thickness (height) of about 11.5 cm and a width of about 91 cm for a single bed.

  Therefore, when used as a mattress, the length may be as short as 160 cm. Therefore, in this embodiment, the auxiliary mat 20 separate from the foldable base mat 10 is used adjacently.

<Auxiliary mat 20>
As shown in FIG. 1, the auxiliary mat 20 is configured separately from the four mat portions 11 to 14, and has the same thickness (height) as the four mat portions 11 to 14 and a width of about 11.5 cm. Is a mat of about 91 cm for a single bed, and the length of the auxiliary mat 20 is, for example, 40 cm which is the same as the length of the lower base of the right trapezoid on the side surface of the mat portion 12 in the second step from the top.

  Therefore, when the folding base mat 10 of the present embodiment expanded as shown in FIG. 2 and the auxiliary mat 20 are arranged adjacent to each other, the overall length becomes 160 cm + 40 cm 200 cm as shown in FIG. It can be almost the same as the length of a normal mattress.

<Usage Method of Foldable Mattress 1 of Embodiment>

(When only folding base mat 10 is folded into a triangular shape in side view and used as a cushion)
For example, only the folding base mat 10 is taken out from a storage bag (not shown) in which the folding base mat 10 and the auxiliary mat 20 in a state folded as shown in FIG. As shown in FIG. 4, the mat portion 12 that is the second step from the top is folded so that the lower bottom surface of the mat portion 12 is on the upper bottom surface of the mat portion 13 that is the third step from the top. Then, there are three stages as shown in FIG.

  Next, as shown by the arrows in FIG. 5, the bottom surface of the mat portion 11 which is the uppermost (first stage) about 20 cm in length is the upper bottom surface of the mat portion 12 which is the second stage from the top. Fold it to get on. Then, the foldable base mat 10 including the four mat portions 11 to 14 becomes a four-stage cushion having a substantially right-angled triangular shape in a side view as shown in FIGS.

  Therefore, the foldable base mat 10 that is a four-stage cushion with a substantially right-angled triangle shape when viewed from the side is placed on a bed 2 or the like as shown in FIG. 6, for example, on the floor, carpet, or mattress. Thus, a back cushion having an inclination angle of about 30 degrees and a height of about 46 cm can be obtained.

  As a result, the user hits his / her back, neck, head, etc. on the inclined surface of the folding base mat 10 which is a three-dimensional cushion with a right-angled triangular shape on the bed 2 etc. Since the neck and head can be placed on the apex of the angle, the burden on the neck and spine can be reduced, and a cushion with excellent usability can be formed.

  At this time, as shown in FIG. 8, the auxiliary mat 20 is placed on the bed 2 together with the foldable base mat 10 which is a three-dimensional cushion in a substantially right-angled triangle shape when viewed from the side. Therefore, it may be used at a distance from the folding base mat 10 which is a four-stage cushion, or may be stored under the bed 2 without being used.

(When folding base mat 10 and auxiliary mat 20 are used side by side)
As described above, when the foldable base mat 10 is used without being folded into a four-stage side view substantially right-angled triangle shape, the thickness (height) is about 11.5 cm and the width as described above. Is about 91 cm for a single bed 2 and a mattress with a length of 160 cm.

  However, since this is shorter than the overall length of the mattress of the bed 2 having a normal length of about 200 cm, the foldable base mat 10 and the auxiliary mat 20 of the present embodiment expanded as shown in FIG. Then, the auxiliary mat 20 is about 11.5 cm having the same thickness (height) as the four mat portions 11 to 14, about 91 cm in width, and about 40 cm in length, so that it is widened. A mattress having a width of about 91 cm and a length of about 200 cm is combined with the total length of 160 cm of the folding base mat 10.

  Therefore, when the foldable base mat 10 and the auxiliary mat 20 of the present embodiment thus expanded are arranged adjacent to each other and placed on the bed 2 as a mattress having a width of about 91 cm and a length of about 200 cm, As shown in FIG. 9, it is preferable to use the folding base mat 10 and the auxiliary mat 20 with a sheet or a thin mat 3 so as not to be displaced.

<Main effects of the folding mattress 1 of the embodiment>
As described above, according to the foldable mattress 1 of the embodiment according to the present invention, the mattress is formed by connecting the four mat portions 11 to 14 so as to be foldable at the connecting portion between the adjacent mat portions. When the two mat portions 11 to 14 are spread out, a single mattress is formed. On the other hand, when the four mat portions 11 to 14 are folded at the respective connecting portions, the mat portions at each step are configured by one mat portion. And it is comprised so that it may become a cushion of a right-angled triangle shape in side view by the same four steps as the number of the four mat parts 11-14.

  Therefore, even if the four mat portions 11 to 14 are spread out or repeatedly folded at the connecting portion, the connecting portion is not easily weakened, and if the mat portions are folded at the connecting portion, the four mat portions 11 to 14 Since the thickness is four steps, which is the same as the number of mat portions, the usability as a cushion can be improved.

  Moreover, the foldable mattress 1 according to the embodiment of the present invention is separate from the four mat portions 11 to 14, has the same thickness as the four mat portions 11 to 14, and has the same width and a rectangular side surface. Since the auxiliary mat 20 is provided, the length of the auxiliary mat 20 is about 40 cm, which is the same as the length of the lower base of the right trapezoid on the side surface of the mat portion 12 in the second stage from the top.

  Therefore, when the extended folding base mat 10 and the auxiliary mat 20 are arranged adjacent to each other, the auxiliary mat 20 is about 40 cm in length, so that the width of the auxiliary folding base mat 10 together with the total length of 160 cm is about 40 cm. It can be used as a mattress having a length of about 91 cm and a length of about 200 cm. It can also be used as a mattress having a full length, and the usability can be improved.

  In the description of the embodiment described above, the width of the foldable base mat 10 and the auxiliary mat 20 has been described by taking the width of a single size mattress of about 91 cm as an example. For example, the width for a double size of about 180 cm may be used.

  Further, in consideration of the case where the expanded folding base mat 10 and the auxiliary mat 20 are arranged adjacent to each other, a hook-and-loop fastener may be provided so that the folding base mat 10 and the auxiliary mat 20 are not separated from each other.

  Further, in the present invention, the auxiliary mat 20 is optional and may be omitted. In that case, when it is spread and used as one mattress, it becomes a mattress for a child having a length of about 160 cm. In addition, the dimensions of the folding base mat 10 are adjusted, for example, when the length of each of the four steps of the mat portions 11 to 14 is increased by about 5 cm, and the length is about 200 cm when used as a single mattress. In such a case, the auxiliary mat 20 can be omitted and the foldable base mat 10 alone can be used as an adult mattress.

  In the description of the embodiment described above, the foldable base mat 10 is configured by the four-stage mat portions 11 to 14. However, in the present invention, the number of stages is not limited, and the number of stages is six or eight. Of course, the mat portion may be used.
