Description

  The present invention relates to a tatami-holding frame that is used to prevent a tatami mat from being misaligned around a tatami when laying judo tatami mats on a floor such as a gymnasium.

  Conventionally, as a judo tatami holding frame, between a plurality of frame members that can be disassembled and assembled so as to surround the periphery of the tatami laid on the floor surface, and the opposing frame members of the rectangular frame assembled by this frame member What is provided with the tension belt passed is known (refer patent document 1).

In this case, the tension band is formed by an end member whose one end is fixed to the bottom surface of the frame member, a band member, and a connection plate that integrates the end member and the band member.
As described above, the tension band in the conventional tatami holding frame requires three kinds of members, that is, the end member, the band member, and the connection plate, so that the number of parts is large and the cost is disadvantageous. was there.
Also, as the number of parts increases, it takes time and labor to transport and assemble, and because one end of the end member is fixed to the bottom surface of the frame member, the work becomes complicated and the construction is difficult. There was a problem of being forced to work.

Conventionally, there is known a tatami mat provided with anti-slip means on the bottom surface (see Patent Document 2).
Providing anti-slip means on the bottom surface of the tatami itself in this way raises the problem that the manufacturing cost of the tatami is increased.

  The present invention reduces the number of parts of the tension band, reduces the cost burden and labor and improves the workability by making it easy to connect the tension band to the frame member, and also to the floor surface. It is an object to provide a tatami holding frame that can prevent slipping.

In order to solve the above problems, the tatami holding frame of the present invention is
A plurality of frame members arranged in a frame so as to be disassembled and assembled so as to surround the periphery of the tatami laid on the floor surface, and a tension band passed between opposing frame members of the rectangular frame assembled by the frame members,
The tension band is formed as a continuous band having a length that passes between the opposing frame members.
It is formed so as to be detachably connected to the frame member by turning its end portion from below the frame member so as to be folded and joining it to the upper surface of the tension band with a surface fastener,
And it was set as the structure by which the slip prevention means with respect to a floor surface was provided in the bottom face of the said tension belt.

  In the present invention, since the tension band is formed as a continuous band having a length passed between the frame members, the tension band is sufficient by itself, and unlike the conventional case, the number of parts is reduced. , Cost burden and labor can be reduced.

In addition, the connecting structure of the tension band to the frame member is passed through the end of the tension band under the frame member, and then turned up so that it can be folded back. It has a structure to be joined.
Thus, since it is only necessary to hang the end portion of the tension band around the frame member and join it with the hook-and-loop fastener, the connecting operation can be facilitated and the workability can be greatly improved.

  Further, since the tatami mat is spread in a rectangular frame assembled by the frame member, the periphery thereof is held by the rectangular frame to prevent displacement, and in this state, slipping of the tension band with respect to the floor surface is prevented. Therefore, as a result, it is possible to prevent the tatami mat from being displaced without providing the tatami mat with anti-slip means.

  FIG. 1 is a plan view showing an assembled state of the tatami holding frame of the first embodiment, FIG. 2 is an exploded perspective view showing a connecting structure of frame members in the tatami holding frame, and FIG. 3 is a perspective view showing the connecting structure. FIG. 4 is a perspective view showing a connection structure for a tension band member in the tatami holding frame.

  In the figure, reference numeral 1 denotes a frame member, which is arranged in a frame so that it can be disassembled and assembled so as to surround the judo tatami T laid on the floor surface, and is formed of a wood having a pentagonal cross section with a chamfered portion formed on the outer edge upper part. Then, the rectangular frame 10 is formed by connecting the end faces of the frame member 1 so as to abut each other.

  As shown in FIGS. 2 and 3, the frame members 1 and 1 are connected to each other by forming a groove 11 on the end surface of one frame member 1 and forming a ridge 12 on the end surface of the other frame member 1. Then, the end faces of both frame members 1 and 1 are butted together so that the ridges 12 and the recessed grooves 11 are fitted, and the frame members 1 and 1 are joined by the bracket 13 in the butted state. It has become.

In the embodiment, a judo field with 72 tatami judo tatami mats T is formed. Correspondingly, a rectangular frame 10 in which six frame members 1 are connected in the vertical direction and six in the horizontal direction are connected. It is formed.
In addition, there is no limitation on the number of tatami mats for judo, and there is no limitation on the length of each frame member forming the rectangular frame and the number of connections.
Further, the connection structure between the frame members 1 and 1 is not limited to the structure shown in FIGS. 2 and 3, and an appropriate connection structure can be adopted.

A tension band 2 is passed between the opposing frame members 1 and 1 of the rectangular frame 10.
In the present embodiment, six tension bands 2 are passed in the vertical direction and six in the horizontal direction in correspondence with the number of the frame members 1 in the vertical direction and the number in the horizontal direction.

  The tension band 2 is formed by forming a composite sheet in which a cloth is laminated on the upper surface of a synthetic resin sheet in a band shape, and is formed in a continuous band having a length passed between the frame members 1 and 1 facing each other. ing.

  As shown in FIG. 4, the connection structure of the tension band 2 to the frame member 1 hangs so that the end of the tension band 2 is turned up from below the frame member 1, and the end of the tension band 2 The hook-and-loop fastener 21 attached to the portion by stitching or the like is joined to the hook-and-loop fastener 22 provided on the upper surface of the tension band 2 so as to be detachably connected to the frame member 1.

An anti-slip sheet 23 is attached to the bottom surface of the tension band 2 as anti-slip means.
As the anti-slip sheet 23, for example, a conventionally known anti-slip sheet, anti-slip mat, or the like such as a flexible net-like core material made of polyester covered with an acrylic ester can be used.
Moreover, these anti-slip sheets, anti-slip mats, and the like may be attached to the entire bottom surface of the tension band or may be attached partially. The attachment means may be any means as long as it can attach the sheet, the mat or the like to the bottom surface of the tension band, whether it is stitched or pasted.

Therefore, in the tatami holding frame of the present embodiment, the frame members 1 are connected to form the rectangular frame 10 and the tension band 2 is passed between the opposing frame members 1 and 1 to assemble the tatami holding frame.
If judo tatami T is spread in the rectangular frame 10 of the tatami holding frame assembled in this way, a judo field as judo equipment can be made.

  As described above, since the number of parts of the tension band 2 is small, the cost burden and labor can be reduced, and the connection work of the tension band 2 to the frame member 1 is easy and the workability can be greatly improved. Furthermore, it is possible to provide a tatami holding frame excellent in practicality that can prevent slipping on the floor surface.
