The mat 1 of the present embodiment can be spread and laid on the ground or the like for use. In addition, it can be used like a chair in a folded state. Furthermore, it can be folded or rolled into a compact storage. In addition, in this specification, a mat means to include a rug of various thicknesses such as a sheet.

The mat 1 includes a skeleton structure 100 and a cushion body 200. The skeleton structure 100 is arranged in the middle portion of the outer periphery of the cushion body 200 in the thickness direction, and when the cushion body 200 is inflated, it can be used as a mat 1.

The skeleton structure 100 includes a pair of rod-shaped frames 10, a pair of first connecting members 20, and a pair of second connecting members 30. The rod-shaped frames 10 are arranged in pairs so as to be parallel to each other. Each rod-shaped frame 10 has three rod-shaped members 11 (first rod-shaped member 11a, second rod-shaped member 11b, and third rod-shaped member 11c) and two joints 12. In the present specification, when the first rod-shaped member 11a, the second rod-shaped member 11b, and the third rod-shaped member 11c are not distinguished, they are referred to as rod-shaped members 11. The three rod-shaped members 11 are connected by two joints 12 to form one rod-shaped frame 10.

The first rod-shaped member 11a and the third rod-shaped member 11c have substantially the same length, and the second rod-shaped member 11b is longer than the first rod-shaped member 11a and the third rod-shaped member 11c. However, all three rod-shaped members 11 may have the same length or may have different lengths, and the length may be arbitrarily designed as long as they can be folded as described later.

The joint 12 can rotate at least 180 degrees, as shown in FIG. Further, the joint 12 has a locking function that can be locked at an arbitrary rotation angle. Since the existing joint mechanism can be applied to the joint 12, detailed description thereof will be omitted.

Joints 12 are connected to both ends of the second rod-shaped member 11b, and the first rod-shaped member 11a and the third rod-shaped member 11c are connected to the opposite sides of the second rod-shaped member 11b of each joint 12. The angles of the first rod-shaped member 11a and the third rod-shaped member 11c can be changed, that is, bent / extended with respect to the second rod-shaped member 11b in a plane perpendicular to the plane in which the pair of rod-shaped frames 10 are arranged in parallel. can.

The joint 12 includes coaxially rotatable disk-shaped members 12a and 12b. The member 12a is arranged so as to face the inner surface of the skeleton structure 100 in a plan view, and the member 12b is arranged so as to face the outside of the skeleton structure 100 in a plan view. The second rod-shaped member 11b is connected to the member 12b, and the first rod-shaped member 11a and the third rod-shaped member 11c are connected to the member 12a. Further, each rod-shaped member 11 is connected to the joint 12 so as to be substantially aligned in a plan view and a side view.

The first connecting member 20 is arranged at a right angle to each rod-shaped frame 10 so as to connect the pair of rod-shaped frames 10 to each other. One first connecting member 20 is arranged between a pair of first rod-shaped members 11a and connects them. The other first connecting member 20 is arranged between the pair of third rod-shaped members 11c and connects them.

The first connecting member 20 has two wires 21, a plurality of connecting pieces 22, and a plurality of spacers 23. The two wires 21 are arranged in parallel, and both ends of each wire 21 are connected and fixed to a pair of rod-shaped frames 10. Both ends of one wire 21 are connected to the inner surface (member 12a) of the joint 12, and both ends of the other wire 21 are connected to the inner surface of the rod-shaped member 11. The plurality of connecting pieces 22 are formed in an elongated plate shape, are bridged so as to be orthogonal to the two wires 21, and are arranged in parallel with each other at regular intervals in the wire direction. The two wires 21 are inserted into through holes at both ends of each connecting piece 22. The plurality of spacers 23 are formed in a three-dimensional shape such as a sphere or a cube. The plurality of spacers 23 are passed through the wire 21 and are placed in contact with or in close proximity to the connecting pieces 22 between the plurality of connecting pieces 22. Therefore, the arrangement interval of the plurality of connecting pieces 22 is provided at least by the thickness of the spacer 23. The angle of the first connecting member 20 is changed according to the angle change of the pair of first rod-shaped members 11a and the member 12a.

The second connecting member 30 is arranged at a right angle to each rod-shaped frame 10 so as to connect the pair of rod-shaped frames 10 to each other. The pair of second connecting members 30 are arranged between the pair of second rod-shaped members 11b and connect them.

The second connecting member 30 has two wires 31, a plurality of connecting pieces 32, a plurality of spacers 33, and two tubular members 34. The tubular member 34 as a wire mounting member is a hollow ring-shaped member, is provided so as to fit on the outer periphery of the second rod-shaped member 11b, and can move in parallel with the axial direction of the second rod-shaped member 11b. The two wires 31 are arranged in parallel, and both ends of one wire 31 are connected and fixed to the pair of tubular members 34. The plurality of connecting pieces 32 are formed in an elongated plate shape, are bridged so as to be orthogonal to the two wires 31, and are arranged in parallel with each other at regular intervals in the wire direction. The two wires 31 are inserted into through holes at both ends of each connecting piece 32. Both ends of the other wire 31 are connected and fixed to the connecting pieces 32 arranged at both ends. The plurality of spacers 33 are formed in a three-dimensional shape such as a sphere or a cube. The plurality of spacers 33 are passed through the wire 31 and are placed in contact with or in close proximity to the connecting pieces 32 between the plurality of connecting pieces 32. Therefore, the arrangement interval of the plurality of connecting pieces 32 is provided by the thickness of the spacer 33. The second connecting member 30 can be translated along the axial direction of the rod-shaped member 11 together with the tubular member 34.

Here, each connecting piece 22 and each spacer 23 of the first connecting member 20 are arranged in contact with each other or in close proximity to each other. Further, spacers 23 are arranged at both ends of the wire 21, and these spacers 23 are in contact with or in close contact with the rod-shaped frame 10. When a moment in the compression direction as shown by the arrow M1 in FIG. 2 is generated with respect to the first connecting member 20 by the relative movement of the pair of rod-shaped frames 10, the connecting piece 22 and the spacer 23 come into contact with each other and are compressed. By doing so, it acts to resist the moment. One of the wires 21 acts against the generated moment due to its tensile force.

Each connecting piece 32 and each spacer 33 of the second connecting member 30 are arranged in contact with each other or in close proximity to each other. Further, connecting pieces 32 are arranged at both ends of the wire 31, and these connecting pieces 32 are in contact with or in close contact with the rod-shaped frame 10. When a moment in the compression direction as shown by the arrow M2 in FIG. 2 is generated with respect to the second connecting member 30 by the relative movement of the pair of rod-shaped frames 10, the connecting piece 32 and the spacer 33 come into contact with each other and are compressed. By doing so, it acts to resist the moment. One of the wires 31 acts against the generated moment due to its tensile force.

With such a configuration of the connecting member, the strength of the entire skeleton structure 100 is improved. Needless to say, when the pair of rod-shaped frames 10 move in a direction in which they are relatively separated from each other, the tensile force of the wire of the connecting member acts to act. Each connecting piece may be fixed to the wire so as not to move in the wire direction. Each spacer may be fixed to the wire so that it does not move in the direction of the wire. Further, each spacer may be integrally formed on one side of the connecting piece and may be fixed to one side of the connecting piece.

Further, the connecting pieces 32 of the second connecting member 30 are inserted at intervals of the connecting pieces 22 of the first connecting member 20 and arranged so as to be alternately combined (meshed) with the connecting pieces 22. (Figs. 3 and 4). With the joint 12 rotated by, for example, 90 degrees by holding the first rod-shaped member 11a and / or the third rod-shaped member 11c (FIGS. 4A and 4B), the tubular member 34 of the second connecting member 30 is attached. It can be moved to combine (mesh) the ends of the connecting pieces 22 and 32 of the first connecting member 20 and the second connecting member 30 (FIG. 4 (c)). At this time, the end of each connecting piece 22 and the end of each connecting piece 32 are in contact with each other or in close proximity to each other. By this combination, the first connecting member 20 and the second connecting member 30 act more strongly on the moments shown by the arrows M1 and M2 in FIG. 2 described above.

The cushion body 200 has a bag shape and is used by inflating it by injecting air through a sealable air hole. The material is not particularly limited, but is, for example, vinyl chloride resin used for a floating ring or the like. The cushion body 200 has a substantially rectangular parallelepiped shape in an inflated state. The cushion body 200 has a recessed portion in an intermediate portion in the thickness direction of the outer periphery, and is formed so that the skeleton structure 100 fits into the recessed portion. The skeleton structure 100 is arranged so as to be covered with the cushion body 200.

The cushion body 200 is divided into three cushion bodies 201, 202, and 203. The cushion body 201 is arranged so as to cover a part of the pair of first rod-shaped members 11a and the pair of first connecting members 20. The cushion body 202 is arranged so as to cover the pair of second rod-shaped members 11b, a part of the pair of first connecting members 20, and the pair of second connecting members 30. The cushion body 203 is arranged so as to cover a part of the pair of third rod-shaped members 11c and the pair of first connecting members 20. By dividing the cushion body 200 in the vicinity of the common axis of the opposing joints 12 in parallel with the axis, the joints 12 can be smoothly rotated.

The cushion body 202 is provided with a recessed portion along the entire outer circumference. On the other hand, the cushion bodies 201 and 203 are provided with recessed portions along three sides of the outer circumference, and the recessed portions are not provided at the portions corresponding to the ends of the short sides of the mat 1 (FIG. 1 (c)). This is because the skeleton structure 100 to be covered is not arranged.

When the cushion body 200 is inflated, the skeleton structure 100 fits into the recess of the cushion body 200 and becomes stable as if it were sandwiched between the cushion bodies 200. The cushion body 200 can be removed from the skeleton structure 100 after being deflated and shrunk.

Next, an example of using the mat 1 will be described. The mat 1 can be used in a flat state in which the rod-shaped member 11 is extended and opened as shown in FIG. 1, and can also be used as shown in FIG.

FIG. 6 shows an example of the use of the mat 1. As shown in FIG. 1, the pair of first rod-shaped members 11a and the pair of third rod-shaped members 11c are bent 90 degrees from a state in which the rod-shaped members 11 are extended and opened. Then, the cylindrical member 34 exposed on the side surface of the cushion body 200 is moved to combine the connecting piece 22 of the first connecting member 20 with the connecting piece 32 of the second connecting member 30. The pair of first rod-shaped members 11a and cushion body 201, the pair of third rod-shaped members 11c and cushion body 203 can be used as legs, and the pair of second rod-shaped members 11b and cushion body 202 can be used as a seat. can. By engaging the connecting piece 32 of the second connecting member 30 with the connecting piece 22 of the first connecting member 20, when a vertical force is applied to the surface of the cushion body 202 which is the seat portion, the first view is seen from above. It is possible to prevent the connecting member 20 from bending toward the center of the plane in which the second rod-shaped member 11b is arranged in parallel or in the opposite direction, that is, the cushion bodies 201 and 203 from bending.

The mat 1 in FIG. 6 is turned upside down so that the pair of the first rod-shaped member 11a and the cushion body 201 and the pair of the third rod-shaped member 11c and the cushion body 203 form a backrest (or a wall or a partition), and the pair of first rod-shaped members 11a and the cushion body 201 are used as a backrest (or a wall or a partition). 2 It can also be used as a chair or bed in which the rod-shaped member 11b and the cushion body 202 serve as a seat. A pair of first rod-shaped members 11a or a pair of third rod-shaped members 11c may be extended to expand the seat portion.

FIG. 7 shows a state in which the mat 1 is folded. Since the joint 12 rotates 180 degrees, the rod-shaped frame 10 can be folded and folded compactly.

After the pair of rod-shaped frames 10 are in the extended state, the air in the cushion body 200 is evacuated. The pair of first rod-shaped members 11a is rotated 180 degrees and superposed on the pair of second rod-shaped members 11b. Further, the pair of third rod-shaped members 11c is rotated by nearly 180 degrees and overlapped with the pair of first rod-shaped members 11a. As an example, the overlapping tip portions of the first rod-shaped member 11a and the third rod-shaped member 11c shown in FIG. 7 may have a substantially semicircular cross section so that the planes overlap each other. By doing so, the height can be reduced when the tip portions of the first rod-shaped member 11a and the third rod-shaped member 11c are overlapped with each other. By the work up to this point, the area of the mat 1 in a plan view can be reduced.

Further, the cushion body 200 and the first connecting member 20 are held by holding one second rod-shaped member 11b (front side of the paper surface in FIG. 7) and rolling toward the other second rod-shaped member 11b (back side of the paper surface in FIG. 7). , And the second connecting member 30 are rolled into a roll shape. The first connecting member 20 and the second connecting member 30 are orthogonal to the rod-shaped member 11 together with the wires 21 and 31 because the plurality of plate-shaped connecting pieces 22 and 32 have an interval in the direction parallel to the rod-shaped member 11. Can be rolled and folded in the direction of the wire.

According to the mat 1 of the present embodiment, a mat that can be used in a bent state is provided.

Since the mat 1 can be kept in a bent state, it can be used not only by laying it on a flat surface but also as a chair or a backrest. Further, since it can be locked at an appropriate angle, one end of the mat 1 can be bent and fixed to be used as an intrusion guard for infants, a grip bar, or a blindfold.

Further, since the mat 1 has a pair of rod-shaped frames 10 connected by a connecting member composed of a wire and a plurality of connecting pieces, the mat 1 has the flexibility to be rolled and folded in a direction orthogonal to the pair of rod-shaped frames. , At least for a specific moment (arrows M1 and M2 in FIG. 2). Therefore, the rod-shaped member can be folded and then rolled to be compactly folded, which makes it convenient to carry.
