Description

  The present invention relates to a foldable board made of a flat plate having a predetermined thickness.

For example, a flat plate such as a board or a mat is used for the purpose of warming and protecting a human body in camping or leisure (Patent Document 1). In Patent Document 1, a mat having a predetermined thickness and elasticity is provided with incisions alternately on the front and back sides at a predetermined interval, leaving a slight thickness. As a result, when not in use, the mat can be folded in a bellows shape and stored compactly when it is bent so that the cut is on the outside. Furthermore, there is a method of compacting the mat or board into a round shape when not in use.
JP-A-5-211917

  The thing of the said patent document 1 uses sponge-like foaming synthetic resin as a main raw material. When a mat or board made of such an elastic material is folded into a bellows shape, the folds will be attached to the front and back during storage. For this reason, even if such a mat or board is developed, it is difficult for the mat to be flat due to folds. In addition, a round wound shape also has a curl during storage, and even if the mat or board is unfolded, the curl is difficult to flatten. For this reason, there has been a problem that the mat or board cannot be formed into a uniform flat shape during use, which makes it difficult to use.

  In view of the above problems, the present invention provides a foldable board that can be folded compactly when not in use and easy to store, and can be flat when used and easy to use.

  The foldable board according to the present invention includes a use state in which a plurality of flat plate-like bodies having cushioning properties are continuously provided via a first bent portion, and the flat plate-like bodies are arranged on the same plane. Displacement from a non-use state in which it is bent through a bent portion to form a spiral shape is possible.

  According to the folding board of the present invention, since the flat plate itself is not folded, it becomes difficult to bend the flat plate even when folded through the bent portion, and it is folded into a conventional bellows shape. Compared to the case, it is possible to prevent the plate-like body itself from being folded. In addition, it is difficult for the end portion to spring up when the flat plate is developed, and it is possible to prevent the flat plate from being curled compared to the conventional round roll.

  It can have a 2nd bending part which makes the said flat plate shape bendable in the direction orthogonal to the said 1st bending part. As a result, when the second bent portion is bent to make the flat plate-like body L-shaped, the second bent portion straddles the plurality of first bent portions at the second bent portion. Can be extended, and the plate-like body can be extended more uniformly.

  In a non-use state in a spiral shape, the first bent portion may be directed outward, or the first bent portion may be directed inward.

  The spiral shape in the unused state can be rectangular or elliptical.

  Another foldable board according to the present invention includes a board body formed by connecting a plurality of flat plate-like bodies having cushioning properties via a bent portion, and a core member that winds the board body in a spiral shape. The core member has an elastic force for maintaining the board body in a spiral shape in a free state, and allows the development of the board body by applying a drawing force against the elastic force.

  According to another foldable board of the present invention, since the core member is provided to wind the board body in a spiral shape, the core member maintains the board body in a spiral shape and resists this elastic force. Deployment of the board body can be allowed by applying a pull-out force. In addition, since the plate body can be used as the board body, the board body is less likely to be creased, and the board body folds compared to the case of folding in a conventional bellows shape. Can be prevented. In addition, it is difficult for the end portion to pop up when the board main body is unfolded, and it is possible to prevent the plate-like body from being curled compared to the case of the conventional round winding shape.

  Since the folding board of the present invention can prevent the plate-like body from being folded or folded, the plate-like body can have a flat surface and is easy to use at the time of use. Moreover, when not in use, it can be folded compactly and stored easily. Furthermore, since it is sufficient to wind the flat plate in one direction, there is an advantage that it is easy to wind.

  When the second bent portion is provided, the flat plate-like body can be extended more uniformly, which makes it easier to use.

  When the core member is provided, the winding work of the flat plate can be easily performed. That is, it is possible to facilitate the switching operation between the coiled folded state and the unfolded used state, and the folding can be performed with an elastic force, so that the operability is further improved.

  Embodiments of the present invention will be described below with reference to FIGS.

  The foldable board according to the first embodiment of the present invention is, for example, a mat having a heat retaining / protecting function for humans, and is used by developing the mat into a flat plate shape during use. When in use, it can be folded compactly.

  The foldable board 1 according to the first embodiment, as shown in FIG. 1, connects the flat bodies 6a, 6b,... 6h via the first bent portions 2a, 2b,. The flat bodies 6a, 6b, ... 6h are arranged in the same plane. The front surface 1a of the folding board 1 has first bent portions 2a, 2b,... 2g formed from cuts extending parallel to the short sides 4a, 4b. A plurality of first bent portions 2a, 2b,... 2g are provided at predetermined intervals. Here, the predetermined interval is an interval that enables the flat body as shown in FIG. 2 to be bent, and the first bent portions 2a, 2b,... 2g are arranged at unequal pitches. ing. Thus, the first flat plate body 6a, the second flat plate body 6b, the third flat plate body 6c,..., The eighth flat plate body 6h are folded through the first bent portions 2a, 2b,. Can be tuneable. Further, the folding board 1 has a second bent portion that can bend the flat bodies 6a, 6b,... 6h in a direction orthogonal to the first bent portions 2a, 2b,. 3. Accordingly, the first flat plate body 6 a, the second flat plate body 6 b, the third flat plate body 6 c... The eighth flat plate body 6 h can be bent via the second bent portion 3. it can.

  When the foldable board 1 is not in use, the foldable board 1 is stored in a folded state in a rectangular shape as shown in FIG. That is, first, the first flat plate 6b is bent so that the first bent portion 2a is on the outside, and the second flat plate 6b is overlapped with the back 1b of the first flat plate 6a and the back 1b of the second flat plate 6b. One plate 6a is bent. Next, the third flat plate 6c is bent to the outside so that the second flat plate 6b and the third flat plate 6c are substantially perpendicular to each other. The body 6b is bent. Similarly, each flat plate is bent so as to be at right angles. In this manner, the eighth flat plate body 6h is bent with respect to the seventh flat plate body 6g by bending the seventh bent portion 2g so as to be outside. Accordingly, the folding board 1 is folded in a spiral shape so that the front surface 1a is on the outside and the back surface 1b is on the inside.

  When the foldable board 1 is used, it is used in an unfolded state as shown in FIG. That is, all the first bent portions 2a, 2b,. In this case, when the second bent portion 3 is bent to make the flat plate-like body L-shaped, the second bent portion 3 is a second fold across the plurality of first bent portions 2a, 2b,. The first bent portions 2a, 2b,... 2g can be extended at the bent portion 3. Thereby, the surface from the 1st flat plate-like body 6a to the 8th flat plate-like body 6h can be made flat.

  According to the present invention, since the flat body itself is not folded, it becomes difficult for the flat body 6 to be folded even when folded through the bent portions 2a, 2b,. It is possible to prevent the plate-like body 6 from being folded as compared with the case where it is folded into two. In addition, since the ends 4a and 4b are less likely to spring up when the flat plate body 6 is deployed, it is possible to prevent the flat plate body 6 from being curled compared to the conventional round roll shape, The flat plate-like body 6 can be a flat surface, which is easy to use when used. Moreover, when not in use, it can be folded compactly and stored easily. Furthermore, since the flat plate-like body 6 has only to be wound in one direction, there is an advantage that it is easy to wind.

  It can have the 2nd bending part 3 which makes the said flat body 6 bendable in the direction orthogonal to 1st bending part 2a, 2b ... 2g. Thereby, when the 2nd bending part 3 is bend | folded and a flat plate-shaped body is made into L shape, the 2nd bending part 3 straddles a plurality of 1st bending parts 2a, 2b ... 2g, and 2nd folding The first bent portions 2a, 2b,... 2g can be extended by the bent portion 3, and the flat plate-like body can be extended more uniformly. This makes it easier to use.

  Next, as a second embodiment of the foldable board according to the present invention, as shown in FIG. 3, a back surface 1b of the foldable board 1 is formed with a notch extending in parallel with the short sides 4a and 4b. One folding part 2a can also be formed. When not in use, the foldable board according to the second embodiment is stored in a folded state so that the respective first bent portions 2a, 2b,... 2g are inside as shown in FIG. The In this case, the flat plate-like body 6 is bent by the same method as in the first embodiment. Accordingly, the folding board 1 is folded in a spiral shape so that the front surface 1a is on the outside and the back surface 1b is on the inside.

  Next, as the third embodiment of the folding board of the present invention, a very flexible material can be used for the flat body 6. As shown in FIG. 5, this material is a material that can be bent so as to be elliptical in a folded state. Thereby, in 3rd Embodiment, as shown in FIG.4 and FIG.5, the number of 1st bending parts 2a-2d can be decreased. In this case, since the number of the first bent portions 2a to 2d is small and the adjacent surfaces are not perpendicular to each other through the first bent portions 2a to 2d, the folds at the first bent portions 2a to 2d There is an advantage that becomes more difficult to adhere.

  Next, a folding board according to a fourth embodiment of the present invention will be described. In this case, a board main body 21 formed by connecting a plurality of flat plate-like bodies 6 having cushioning properties via the bent portion 2 and a core member 11 for winding the board main body 21 in a spiral shape are provided, and the core The member 11 has an elastic force for maintaining the board main body 21 in a spiral shape in a free state, and the board main body 21 can be allowed to expand by applying a drawing force against the elastic force. That is, the board body 21 that is the flat body 6 is joined to the core member 11 via the cloth 10. The core member 11 includes a pipe member 13, a winding spring (not shown) provided inside the pipe member 13, and a shaft 12. Then, when the shaft 12 is rotated, the board body 1 can be wound, and when the shaft 12 is rotated in the opposite direction, the board body 21 can be unfolded. In addition, a stopper (not shown) can be provided, and only the flat plate 6 having a desired length can be developed, so that the application can be expanded (in this case, the second bent portion). It is impossible to bend the portion 3 into an L shape, and the first bent portions 2a, 2b,... 2g and the second bent portion 3 are used in an extended state.

  Thus, in the foldable board according to the fourth embodiment of the present invention, when the core member 11 is provided, the winding work of the flat plate-like body 6 can be easily performed. That is, it is possible to facilitate the switching operation between the coiled folded state and the unfolded used state, and the folding can be performed with an elastic force, so that the operability is further improved. Also, by providing the stopper, it is possible to develop only a flat plate having a desired length, and the application can be expanded.

  As described above, the embodiment of the present invention has been described, but the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the shape of the flat plate-like body 6 is not limited to a rectangular shape, It may be a square. Various materials such as urethane, rubber sponge, polyolefin foam and the like can be used as the material of the flat plate-like body 6. Moreover, you may make the cutting depth of each 1st bending part 2 and the 2nd bending part 3 differ. A film, non-woven fabric, cloth, aluminum foil or the like may be welded or adhered to the entire surface of the flat plate-like body 6 according to the present invention.

  The number and arrangement pitch of the first bent portions 2 can be variously changed, and two or more second bent portions 3 can be provided. In the said embodiment, although the 1st bending part 2 was provided in the unequal space | interval, it can also be provided in an equal space | interval (for example, 5 cm step), and can also be made into a spiral shape. The usage is not limited to leisure sheets, and when used, the second bent portion 3 may be folded so as to be L-shaped in side view. Furthermore, the foldable board may be used along with things such as luggage and box-type objects (for example, pet cages).
