Embodiment for Carrying out the Invention

[0023] Hereinafter, the mattress 10 according to this embodiment will be described with reference to FIGS. 1 to 5. The arrow UP appropriately shown in each figure indicates the upper side with respect to the mattress 10 laid on the floor or the like, the arrow HE indicates the head side direction of the user in the longitudinal direction of the mattress, and the arrow RI indicates the right side direction of the user in the short side direction of the mattress.

[0024] (Overall Structure of Mattress 10) As shown in FIG. 2, the mattress 10 as a stretching mattress according to this embodiment is adapted to be laid on a floor (not shown) and used. The mattress 10 is composed of a plurality of cushions 12. These cushions 12 are composed of a cushion 12A as a first cushion member and a cushion 12B as a second cushion member. In this embodiment, the cushion 12A and the cushion 12B are each composed of 4 sheets. In the following description, when the cushions 12 are described separately according to the reaction force application direction, they are referred to as "cushion 12A" and "cushion 12B", and when there is no need to distinguish them particularly, they may be simply referred to as "cushion 12".

[0025] In the example shown in Figure 3, the mattress 10 has an overall length that is slightly longer than the height of an average-sized adult user, with cushion 12A primarily supporting the head to the waist and cushion 12B supporting the buttocks to the toes.

[0026] As shown in Figure 1(A), each cushion 12 is configured to generate a deflected reaction force F in response to an overhead load W. As shown in Figure 3, the mattress 10 is formed to support the back of the head, back, waist, and legs of a user M in a supine position and includes a cushion 12A that generates a reaction force FA toward the head and a cushion 12B that generates a reaction force FB toward the legs.

[0027] Furthermore, as shown in Figure 2, the mattress 10 is designed so that the orientation of the cushions 12 can be changed. In other words, the cushions 12 are formed with the same width, length, and thickness, and the direction of the reaction force can be reversed by inverting each cushion 12 or rotating them 180 degrees within the same plane.

[0028] (Key structural components of mattress 10) Figure 1(B) is an enlarged perspective view showing the inside of the cushion 12 in this embodiment. In this embodiment, as an example, eight cushions 12 have the same structure.

[0029] As shown in Figure 1(B), the cushion 12 is composed of a flat first mat base 14 extending in the width direction and length direction of the mattress, a flat second mat base 16 positioned opposite the first mat base 14, and a reaction force applying part 18 connecting the first mat base 14 and the second mat base 16 in the thickness direction of the mattress.

[0030] Multiple through holes 14A are formed in the first mat base 14. Each through hole 14A is formed in a substantially elongated shape with the sheet width direction as the longitudinal direction, and is arranged at equal intervals in the mattress width direction. In addition, the through holes 14A are formed at equal intervals in the mattress length direction.

[0031] The second mat base 16 has the same shape as the first mat base 14 and is positioned at a predetermined distance from the first mat base 14 in the direction of the mattress thickness. In addition, the second mat base 16 has through holes 16A formed in it, similar to the first mat base 14.

[0032] The reaction force applying section 18 is formed such that its cross-sectional shape, when viewed from the width direction of the mattress, is approximately S-shaped. Furthermore, the reaction force applying sections 18 are formed at equal intervals with predetermined spacing in the length direction of the mattress, and each reaction force applying section 18 extends from one end to the other in the width direction of the cushion 12. As shown in Figures 2 and 3, in the case of cushion 12A, its reaction force applying section 18 is approximately S-shaped, curving towards the head side from the first mattress base 14 toward the second mattress base 16, and then curving toward the leg side. As a result, cushion 12A generates a reaction force FA toward the head side. In the case of cushion 12B, the opposite is true.

[0033] More specifically, Figures 1(C) and (D) are enlarged cross-sectional views of the reaction force applying section 18, with (C) showing the reaction force applying section 18 in an unloaded state and (D) showing the reaction force applying section 18 in a compressed state. In the unloaded state shown in Figure 1(C), when the second mat base 16 is placed on the floor or the like and the first mat base 14 is pressed by the user M's body, the reaction force applying section 18 elastically deforms in the direction of compression and transitions to the compressed state shown in Figure 1(D). That is, the compression deformation of the reaction force applying section 18 reduces the distance between the first mat base 14 and the second mat base 16.

[0034] In the state shown in Figure 1(D), a reaction force FA acts from the first mat base 14 toward the user M's body, directed upwards and toward the head of the mattress 10, as indicated by the arrows in the figure. In other words, the cushion 12A is configured to exert a reaction force FA toward the head of the mattress 10 toward the head, back, and waist of the user M upon contact.

[0035] On the other hand, if the cushion 12 shown in Figure 1(C) is reversed or positioned 180 degrees in the opposite direction, the direction of the reaction force applying part 18 will be reversed. In this state, the second mat base 16 is located on the user side, so the second mat base 16 is pressed towards the first mat base 14 side. As a result, a reaction force FB (see Figure 3) acts from the second mat base 16 toward the occupant, directed upwards toward the legs of the mattress 10. In other words, simply by positioning the cushion 12A so that the direction of the reaction force applying part 18 is reversed, the cushion 12B is configured so that the direction in which the reaction force F acts is reversed.

[0036] Furthermore, as shown in Figure 2, the mattress 10 has multiple cushions 12 arranged in the middle section such that the reaction forces F are opposite. Specifically, the mattress 10 is composed of four cushions 12A arranged continuously on the head side and four cushions 12B arranged continuously on the leg side. These cushions 12A and 12B are covered with covers 24 and 26. In addition, the front and back surfaces of each cover 24 and 26 are marked with a mountain-shaped (V-shaped) pattern 20 so that the direction in which the reaction forces FA and FB act can be visually determined.

[0037] Furthermore, as shown in Figures 4(A) to (C) and Figures 5(A) and (B), by changing the arrangement of the cushions 12A and 12B of the mattress 10, it is possible to change the position of the boundary portion 22 to which the direction of action of the reaction force F is deflected. Specifically, by changing the arrangement in reverse from one in which the boundary portion 22 is located at the neck (see Figure 4(A)) to one in which the boundary portion 22 is located at the waist (see Figures 4(B) and 5(B)), or one in which the boundary portion 22 is located at the legs (see Figure 4(C)).

[0038] Furthermore, as shown in Figure 5(C), the cushions 12A and 12B that make up the mattress 10 are made of the same size, so they can be stacked and stored compactly.

[0039] (Operation and effects of this embodiment) Next, the operation and effects of the mattress 10 according to this embodiment will be described.

[0040] According to the mattress 10 of this embodiment, cushion 12A is positioned at least towards the head of the user M in a supine position, and cushion 12B is positioned at least towards the feet of the user M in a supine position.

[0041] In this embodiment, when user M is using the mattress, cushion 12A generates a reaction force FA on the user M's head side and in a deflection direction intersecting the load input direction. On the other hand, when user M is using the mattress, cushion 12B generates a reaction force FB on the user M's foot side and in a deflection direction intersecting the load input direction. As a result, the user M's body in a supine position is stretched in opposing directions on the cushion 12A side and cushion 12B side, and the user M's trunk is stretched in a supine position. Consequently, the mattress 10 according to this embodiment can stretch the human body without restricting the user M's posture.

[0042] Furthermore, in this embodiment, a plurality of reaction force-applying parts 18 are arranged between the first mat base 14 and the second mat base 16 of the cushion 12, and these reaction force-applying parts 18 connect the two in a substantially S-shape when viewed from the side, so that the elastic restoring force of the reaction force-applying parts 18 acts directly on the mat base that the user M is in contact with. As a result, the mattress 10 according to this embodiment can efficiently stretch the target area.

[0043] Furthermore, in this embodiment, the boundary portion 22 between cushion 12A and cushion 12B is located in either the neck, waist, or legs, thus extending the trunk, including the neck, waist, and legs. As a result, the mattress 10 according to this embodiment can be expected to improve blood flow to the trunk, including the neck, waist, and legs, and provide fatigue reduction and lower back pain prevention and improvement effects.

[0044] Furthermore, in this embodiment, since cushions 12A and 12B are divided into multiple pieces in the longitudinal direction of the mattress, the direction of the reaction force F acting on the body can be changed by reversing the orientation of the divided cushions 12 or rotating them 180 degrees. In addition, the divided cushions 12 can be stacked for storage. As a result, the mattress 10 according to this embodiment allows for adjustment of the area to be stretched and reduces storage space.

[0045] Furthermore, in this embodiment, the cushions 12A and 12B are covered by covers 24 and 26, and patterns 20 that allow for the determination of the reaction force deflection direction are displayed on the front and back surfaces of these covers 24 and 26. Therefore, by looking at the patterns 20, it is possible to determine which direction the reaction force deflection direction of the cushions 12A and 12B is facing. As a result, the mattress 10 according to this embodiment allows for the easy and quick placement of the cushions 12A and 12B.

[0046] In this embodiment, both cushions 12A and 12B are divided into multiple pieces, but the configuration is not limited to this, and either one of them may be divided.

[0047] Furthermore, in this embodiment, the pattern 20 is applied to both the front and back surfaces of the covers 24 and 26, but this is not limited to this, and the pattern 20 may be applied to only one of them. Moreover, the pattern 20 may be applied only to the front surface, rather than to both the front and back surfaces. [Explanation of Symbols]
