Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention places a plurality of floor units having level-adjustable support legs on a floor base such as a concrete slab at desired intervals. In addition, the present invention relates to a floor structure in which a flooring material is provided on these floor units and a finishing material is provided on the flooring material, and particularly to a floor structure suitable for application to exercise facilities such as an aerobics field and a kendo field. Things.

[Conventional technology]

In the conventional floor structure, as shown in FIG. 5, a floor unit 2 having a support leg 1 whose level can be adjusted is placed on a floor base such as a concrete slab at a desired interval. Disposing material 3 on body 2 and finishing material on disposing material 3
There are 100. The space between the floor units 2 is indicated by reference numeral 4,
An elastic body provided at the lower end of the support leg 1 is indicated by reference numeral 200. The elastic body 200 is provided with a metal fitting 202 provided with a female screw part 201 as shown in FIG. 6, and the male screw part at the lower end of the support leg 1 is screwed into the female screw part 201.

[Problem to be solved]

In the conventional floor structure, the finishing material 100 has a width of 75 to 90 mm, a length of 300 to 1200 mm, and a thickness of 15 to 18 mm. With such a small version of the finishing material, the floor is disordered due to changes in humidity,
That is, joint blanking, blistering and the like were likely to occur. Also, interval 4
By providing this, the workability is excellent by adjusting this space 4 according to the size of the room at the time of construction, but due to the existence of such space 4 and the small finish material 100, the difference in rigidity on the floor surface Had occurred. When the rigidity of the entire floor varies as described above, the elasticity of the floor of the exercise facility varies, and the feeling of exercise and the degree of ball bounce also vary. In addition, the spring characteristics with respect to the impact force on the floor tend to vary, and the sound insulation also varies. When the nail 101 is hit as shown in FIG. 7 to fix the finishing material 100, when a load is applied from above the finishing material 100, the holding force of the nail 101 is increased due to the existence of the interval 4. The nail 101 may fall down and the nail 101 may come off.

Therefore, the present invention provides a floor structure in which the variation in the elasticity of the floor when exercising on the floor is reduced, the deviation due to the change in the humidity of the finishing material is prevented, and the holding force of the nail against the deformation of the floor is prevented from lowering. The purpose is to do. It is another object of the present invention to provide a floor structure in which the variation in sound insulation is suppressed and the cushioning property is improved. It is still another object of the present invention to provide a floor structure in which a person exercising can feel as vibration from the floor when performing exercise such as aerobics.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a floor unit such as a concrete slab which is provided with a plurality of floor units having level-adjustable support legs at desired intervals. In a floor structure in which a discarding material is provided on the upper side and a finishing material is provided on the discarding material, an elastic body is provided at a lower end portion of the support leg, the elastic body is hollow inside, and seats are provided on inner and outer surfaces. It has a bent portion and is further provided with an air hole for releasing air from the internal space.

[Action]

In the present invention, when a load is applied from above the floor, the elastic body is initially soft and can support the floor, and when further load is applied, the buckling portion buckles and the spring constant of the elastic body increases. It becomes hard. As a result, when performing aerobics and other dances on the floor, a soft feel is obtained for small inputs to the floor, such as bending and stretching movements and small jumps, reducing the burden on the knees and the like, and making a large input to the floor. For example, it becomes stiff for a large jump, and the foothold for the jump is assured.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, a support leg 1, a floor unit 2, a piling material 3, and an interval 4 have the same configuration as the conventional one. The finishing material 5 provided on the sacking material 3 used had a width of 100 mm or more and a length of 1750 mm or more. The longitudinal direction of the finishing material 5 is provided so as not to coincide with the longitudinal direction of the floor unit 2. Further, the space 4 between the floor units 2 in the short direction as much as possible
It is preferable that, for example, 90% or more of the longitudinal boundaries between the finishing materials 5 do not coincide with the space 4 between the floor units 2 in the transverse direction. As the floor unit 2, a rectangular unit of 910 × 1820 (mm) was used, and six to eight support legs 1 were provided thereon. The interval 4 is 200 mm or less, and the scraping material 3 is a particle board (20 mm or 15 mm thick) or plywood (15 mm thick).
Or 12 mm). In addition, it is not necessary to leave an interval between the floor units 2 in the longitudinal direction of the floor units 2 (points where the short sides are opposed to each other), and an interval similar to the interval 4 may be provided between them. Finishing material 5
Here, the one having a width of 145 mm, a length of 1820 mm, and a thickness of 15 mm was used. The elastic body 6 provided at the lower end of the support leg 1
As shown in the figure, it is placed on a floor base 7 and has an air hole 6A for allowing air from the internal space to escape and a buckling portion 6B. Accordingly, when a load is applied from above, the air in the elastic body 6 can escape from the air holes 6A, and the buckling portion 6B buckles, so that the floor can be initially softly supported and then hardened. . Therefore, when performing a normal exercise on the floor, a soft feel can be obtained. That is, the use of the elastic body 6 improves the shock absorbing effect.

FIG. 3 shows an example in which a vibrator 8 is attached to the back surface of the piling material 3 at the location of the interval 4. FIG. 4 shows a case where the vibrator 8 is attached to the back surface of the floor unit 2. These vibrators 8
It is, of course, possible to mount both at the location shown in FIG. 3 and at the location shown in FIG. By activating the vibrator 8, vibrations of a certain rhythm can be given to the floor. For example, when performing a dance such as aerobics on the floor, the body moves while listening to music, and the floor itself vibrates. And a comfortable effect is produced. In the case where the vibrator 8 is mounted at the location of the interval 4 as shown in FIG. 3, the height of the floor can be kept low. In addition, when the vibrator 8 is provided on the back surface of the floor unit 2 as shown in FIG. 4, the floor unit 2 and the waste material 3 and the finishing material 5 at this location are configured to be removable even after construction. Thereby, maintenance of the vibrator 8 after floor construction can be easily performed.

The width of the finishing material 5 is preferably 950 mm or less, and the length is 1850 mm
Hereinafter, as the material, a wood-based large-size laminated material or a non-wood-based large-size finished material in which a synthetic resin, urethane resin, or rubber is attached to a base plate can be used. In particular, a woody large-size laminated finishing material in which a finishing veneer such as birch, oak, beech, itaya, zelkova or the like is laminated on a large-sized plywood is preferable. By using such a large version of the finishing material, variations in the strength, elasticity, and sound insulation of the entire floor are reduced, and the floor is not disordered due to changes in humidity. Will be done.

[Effects] As described above, according to the present invention, a plurality of floor units each having a support leg whose level can be adjusted are placed on a floor base such as a concrete slab at a desired interval. In the floor structure in which the cutout material is provided on the floor unit and the finishing material is provided on the cutout material, an elastic body is provided at the lower end of the support leg, the elastic body is hollow inside, and Since the outer surface has a buckling portion and is further provided with an air hole for allowing air from the internal space to escape, the following operations and effects are achieved. That is, when the input to the floor is small, it is soft, and when the input is large, the buckling portion buckles and becomes hard after buckling, so that the burden on the knee of a person exercising on the floor can be reduced, and large input to the floor by intense exercise In some cases, the floor is hard, so the floor is not too soft and there is no risk of injury. In addition, due to the presence of the air holes, the buffering property and the sound insulating property are also excellent.
