Description

  The present invention is provided between a floor of a gymnasium and a tatami when laying a tatami on a gymnasium or the like, and has a floor structure having an elastic function to absorb a load applied to the tatami and the hardness of the elastic function It is about the method.

  Conventionally, when a sport requiring a tatami facility such as judo is performed in a physical education class at a junior high school or a high school, a floor structure is installed on the floor surface of the gymnasium, and a tatami is laid on the floor structure. As this floor structure, one having an elastic function is used in order to prevent injury to the athlete as much as possible. As a floor structure having such an elastic function, for example, a structure in which two or more plate members each provided with a plurality of support members made of an elastic material are connected in a parallel direction by a rubber joint (Patent Document 1), A structure in which two or more plate members each having a plurality of support members made of an elastic material provided on the lower surface are connected in parallel to each other by a connecting portion protruding from the lower surface of each edge toward the other (Patent Document 2). Are known.

  However, since the adjacent plate member is connected only by the rubber joint, the plate member adjacent to the plate member to which the load is applied does not interlock with the plate member and the plate member. There is a problem that there is a large local step between the tatami mat, the tatami is tilted, and the athlete loses balance. Moreover, since what was described in patent document 2 is made only by the connection part which mutually supports the lower surface of the board member which adjoins the connection of a board member and a board member, the planar direction of a board member and a board member Is not sufficient, and there is a problem that a gap is generated between the plate member and the plate member.

  Therefore, an object of the present invention is to provide a floor structure having an elastic function that hardly causes local steps and gaps and a method for changing the hardness of the elastic function.

  In order to achieve the above object, a floor structure having an elastic function according to the present invention is composed of two or more plate members that constitute a floor plate by being connected in a planar direction, and an elastic material, and the lower surface of each plate member. Provided on the upper and lower surfaces of the edge of one of the plate members adjacent to each other and the support member that supports the plate member, and protrudes toward the edge of the other plate member, A pair of upper and lower connecting portions into which the edge of the other plate member can be inserted, and a fixing member that is formed in a U-shaped cross section and fixes one plate member of adjacent plate members to the other plate member, The floor structure is provided with an elastic function, and a fixing hole into which the leading edge of the U-shaped protruding portion of the fixing member can be inserted is formed in the vicinity of the edge of the upper surface of the plate member. The other plate portion between a pair of connecting portions provided on the member With one edge inserted, one of the leading edges of one fixing member is inserted into the fixing hole of the adjacent one plate member, and the other leading edge is inserted into the fixing hole of the other adjacent plate member. Accordingly, adjacent plate members are fixed to each other in the planar direction.

  As described above, according to the floor structure having an elastic function according to the present invention, adjacent plate members are connected by inserting the edge of the other plate member between the connection portions of the one plate member, It is possible to prevent as much as possible a local step between the plate member and the plate member by interlocking with the plate member adjacent to the plate member to which the load is applied. Further, by fixing the adjacent plate members with respect to the planar direction using a fixing member, it is possible to prevent as much as possible a local gap between the plate member and the plate member. it can.

  In the floor structure having an elastic function according to the present invention, it is preferable that the support member has a quadrangular prism shape, and a plurality of support members are provided at predetermined intervals on the lower surface of each plate member.

  Further, the plate member is preferably formed in a size different from the size of the tatami laid on the floor plate, and thus, by making the plate member constituting the floor plate different in size from the tatami mat, Since the boundary where the plate members are in contact with each other and the boundary where the tatami are in contact with each other can be set at different positions, a floor structure having an elastic function with less local stepping can be obtained.

  Furthermore, it is further provided with the control member which is provided in the outer periphery of the floor board comprised by connecting the said board member in a plane direction, and controls the movement of the tatami laid on this floor board in the parallel direction. Preferably, by providing the regulating member that regulates the movement of the tatami on the outer peripheral edge of the floor board as described above, it is possible to prevent a gap from occurring between adjacent tatami mats as much as possible.

  In addition, the method of changing the hardness of the floor structure having an elastic function according to the present invention includes a plurality of support members provided on the lower surface of the floor plate configured by connecting the plate members in a plane direction. One or more supporting members are changed to those having different restoring forces. Thus, by changing one or more of the support members to one having a different restoring force, the hardness of the floor structure having an elastic function according to the present invention is adjusted to the weight of the target player. Appropriate hardness can be achieved.

  In the method for changing the hardness of the floor structure having an elastic function according to the present invention, two types of support members having different restoring forces are prepared, and the support members adjacent to each other in the vertical and horizontal directions are different from each other. It is preferable to arrange so that.

  As described above, according to the present invention, it is possible to provide a floor structure having an elastic function that hardly causes local steps or gaps and a method for changing the hardness of the elastic function.
