Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a mat that can be used, for example, on a beach or in a tent, and can also be used for water play.

[Conventional technology]

At the beach in summer, you can often see them drying their shells, but since lying directly on them can cause pain and get sand stuck to their bodies, they spread out peach mats and lie on them. . By the way, peach mats include those that have an air chamber and are filled with air to provide cushioning properties, and those that are in the form of a thin sheet.

[Problem to be solved by the invention]

However, each of the conventional mats has the following problems. In other words, in the case of mats with air chambers, if you let the air out and fold them, you can make them very small and not bulky, but it takes time and effort to put air in and out of the air chambers, making it difficult to lay them quickly. There is a problem of not being able to do it or put it away. Moreover, because it contains air, many people use it for playing in the water, and some even lie on it while floating in the water. However, this type of mat has a weak backbone, so if a person stands on it, it will often bend in the middle, creating a risk of the person drowning. On the other hand, thin sheets have the advantage of being easy to spread out and lay out without the hassle of putting air into the air chambers, and can be easily rolled up or folded to make something less bulky. It goes without saying that it cannot be used for things like, for example, but since it is relatively thin, there is the problem that the unevenness of the beach can reach the surface of the sheet and cause pain when lying on it, such as on a beach with many stones. In view of these circumstances, this invention is not only easy to carry and install, but also floats on water.
It will not bend even if a person is placed on it, and
To provide a mat whose unevenness does not affect the mat surface even when laid on an uneven surface.

[Means to solve the problem]

In order to achieve such an object, the present invention provides a plurality of plate materials that have desired rigidity and buoyancy in water and can be stacked and arranged side by side, and that adjoining plate materials are arranged at least in a side-by-side state. The gist of the mat is a mat that is provided with a connecting means that connects the mat at each connecting point, and a bending prevention means that prevents bending in at least one direction of the juxtaposed surfaces at each connecting point.

[For I]

With the above structure, when in use, they can be placed side by side and spread out, placed on a beach, etc., and a person can sit or lie down on them. In addition, they can be placed side by side and floated on water.
Even if a person is placed on it, it will float on the surface of the water, and even if a person is placed on it, it will not bend due to the bending prevention means. On the other hand, when not in use, the plates can be stacked by releasing the connection means of each plate or folding, thereby making the plate more compact.

A locking tongue piece l7 with which one member l8 of the Velcro tape is integrated is provided on one side of the tip, and the other member l9 of the Velcro tape is integrated on the surface of the first plate ll. The method of fixing the ends of the strip material 16 to the first plate material 11 and the fourth plate material is not particularly limited, and examples thereof include bolting, heat fusion, and adhesive methods. . The material for each of the plates 11 to 15 is not particularly limited as long as it has enough rigidity to prevent it from breaking even when a person stands on it and sufficient buoyancy in water, but examples include hollow synthetic resin moldings, etc. Examples include foamed resin such as styrene foam coated with another resin film for waterproofing and reinforcement. Although the connecting means is not particularly limited, for example, there are the following methods. ■ As shown in Figure 3, there are multiple (three locations in the figure) through holes 2l on the side edges of each plate material 11-15 that penetrate through the front and back surfaces.
A method of connecting adjacent plate materials by drilling a through hole 2l and loosely fitting a ring-shaped member 22 into the through hole 2l. In addition,
The ring-shaped member 22 is preferably made of soft synthetic or resin material. In addition, as shown in FIG. 4, the ring-shaped member 22 is
You may change it to 3. ■ As shown in Fig. 5, on one side of the connecting part, the flexible strip material 24 is placed on the surface of the board so as to straddle both sides of the adjacent board, leaving the center part and the edges on both sides. A method of connecting each plate by fixing it to the surface of each plate. In the case of this method, it is preferable that the flexible strip material 24 be fixed such that the adhesion surface is raised and lowered at each connecting portion so that the plate material can be folded alternately as shown by the arrows in the figure. Further, both side edges of the flexible strip material 24 may be fixed by heat sealing or adhesive bonding, but one side edge may be fixed by heat sealing, as shown in FIG. 6, although there is no particular limitation. It is fixed by bonding or adhesive, and the other side edge is dovetailed structure 3
3, it is fixed by a method of fixing it in a separable manner or the like. Furthermore, as shown in FIG. 7 or FIG.
It is also possible to make it freely separable by using 6 or the like. As shown in FIG. 9, the flexible strip material 24 is attached to the plate material 1.
1-15 (only three sheets 11, 12, and 13 are shown in the figure) may also be used as a protective sheet 27 that covers the entire surface. ■ As shown in Figure 1O, a flexible sheet material 28 is sandwiched between the intermediate layers of each of the plate materials 11 to 15 (only three sheets 11, 12, and 13 are shown in the figure),
A method of connecting using this flexible sheet material 28. In this method as well, the flexible sheet material 28
It is also possible to have a structure that can be separated freely using a zipper or Velcro. In addition, instead of the sheet material 28, as shown in FIG.
15 (only three sheets 11, 12, and 13 are shown in the figure) may be sandwiched between intermediate layers. In this case, an insertion hole for the string-like body 29 may be formed in the plate material in advance, and the string-like body 29 may be inserted into the hole later to connect the respective plate materials. In this way, by adjusting the length of the string-like body 29 at both ends, the interval between the plates can be freely changed. ■ A method of connecting using a hinge structure, as shown in Figure 12 or Figure 13. ■ As shown in Figure 14, five plates 11 to 15 (only three plates 11, 12, and 13 are shown in the figure) are placed side by side and surrounded within the bag body 30 and connected by the bag body 30. At the same time, this bag body 3

A method in which each plate material 11-15 is connected rotatably by inserting a plate material locking tool 37 into the through hole 36. Note that the plate material locking tool 37 is composed of a flexible string-like part 37a that connects each of the plate materials l1 to 15, and locking parts 37b provided perpendicularly to both ends of this string-like part 37a. When the locking part 37b is inserted into the through hole 36 along the string-like part 37'a until it passes from the front surface of the plate to the back side, the locking part 37b is again in a position perpendicular to the string-like part 37b. Since it comes into contact with the back of the return plate and is locked, it will not come off in the opposite direction. Therefore, according to this method, the plate material 11-15 can be easily
can be concatenated. Moreover, if the string-like part is damaged, it can be easily replaced. Furthermore, by preparing plate material fasteners with a large number of colors and patterns, it is possible to provide a colorful mat that matches the personality of the user. This mat 1 is constructed as described above, and when not in use, the plates 11 to 15 are folded so as to be stacked on top of each other, as shown in FIG. 18 can be held in the folded state by engaging the other member l9 provided on the surface of the first plate 11. Moreover, since the strip l6 forms a loop when folded, the strip l6 can be easily carried by hanging it. On the other hand, when in use, if the locking tongue piece 17 is released,
Each of the plate materials 11 to 15 can be easily arranged in a desired juxtaposed state. That is, on a beach or the like, each plate material it-t5 can be spread out and placed on the beach so that it has the shape shown in FIGS. 16 to 18, and a person can lie down on it. Moreover, since the plates 11-15 have a certain degree of rigidity, even if there are many stones and the like underneath, the unevenness will not affect the surface of the plates. Furthermore, if the mat l is floated on water with the strip 16 side facing downward, the strip l6 acts as a bending prevention means, and as shown in Figure 19, even if a person is placed on the mat, the mat l will bend at the connecting part. Never. Furthermore, as shown in FIG. 20, this mat 1 may be placed inside a tent 40. FIG. 21 shows a second embodiment of the mat according to the invention. As shown in the figure, the mat 5 includes a plurality of plate members 5l having desired rigidity and water buoyancy, and a plurality of rod members 52. Each plate material 5l has a plurality of parallel through holes 53 formed in the center thereof into which the bar materials 51 are fitted. The bar material 52 is fitted into the corresponding through hole 53 of the parallel plate materials 5l to connect the respective plate materials 51, and also serves as a connecting means to prevent bending at the connecting portion and to prevent bending. It is designed to serve as both a means and a means. In addition, although not shown, the rod 52 is formed by connecting a number of short rods each having a separable connecting means. This mat 5 is as described above, and each board has 5 liters of material.
They can be easily connected together in a side-by-side state, and if they are connected and float on water, they will not sink even if a person stands on top of them. Furthermore, it is safe because it does not bend at the connecting portion. Furthermore, even if the surface on which the device is placed is extremely uneven, such as on a beach, the unevenness will not reach the surface of the mat 5, so the user will not feel any pain even when lying down. Furthermore, by extracting the bar material 52 from the through hole 53, each plate material 5I can be separated and stacked, and
If the bar material 52 is also disassembled into short bars one by one, it can be made to be less bulky and convenient to carry. FIG. 22 shows a third embodiment of the mat according to the present invention. As shown in the figure, the mat 6 includes a plurality of plate members 6l having desired rigidity and water buoyancy. Each plate material 61 can be freely connected to an adjacent plate material 61 by a dovetail structure. That is, a dovetail groove 62 or a dovetail tenon 63 is formed on the side edge of each plate 61, and each plate 61 is formed by fitting the dovetail groove 62 of one plate 6I to the dovetail tenon 63 of the other plate 6I. are made to be freely connectable, and are not bent at the connecting portion. That is, the dovetail groove 62 and the dovetail tenon 63 serve as a connecting means and a bending prevention means. FIG. 23 shows a fourth embodiment of the mat according to the present invention. As shown in the figure, this mat 7 has a plate-shaped magnet 72 or a plate 73 attached to the side wall surface of a plate material 71 instead of the dovetail joint of the third embodiment, and the magnet 72 and the iron plate 73 are bonded together. By joining, each plate material 61 can be freely connected. FIG. 24 shows a fifth embodiment of the mat according to the present invention. As shown in the figure, this mat 8 has a blade part 84 of a clog-shaped member 82 inserted into a retaining hole 83 provided at the side edge of each plate member 81.
By fitting the plates 8I together, the plates 8I can be freely connected. The mat according to the present invention is not limited to the above embodiments. For example, the fourth plate material l4 and the fifth plate material l5 of the first embodiment may be formed into one piece by four plates of the same size, or may be formed by six plates. Further, in the first embodiment, one end of the locking tongue piece l7 is connected to the fifth plate member 1.
