Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor board supporting apparatus for supporting a floor board at a desired height from a floor foundation such as concrete.

[0002]

2. Description of the Related Art Various floor panel supporting devices for supporting a floor panel at a predetermined height from a floor base such as concrete have been proposed. For example, it is described in Japanese Utility Model Laid-Open No. 55-31972 and Japanese Patent Laid-Open No. 9-209548.

[0003] However, as shown in FIG. 4, a conventional floor panel supporting apparatus mounts a lower surface 100a of a rubber or plastic elastic base 100 installed on a floor base surface 50 and a supporting plate 101 for supporting the floor panel. Since both of the mounting surfaces 101a are perpendicular to the axial direction of the support bolt 102, the following inconveniences have been encountered.

That is, usually, the floor base surface 50 is not horizontal, but is often inclined or has a wavy surface. Therefore, when a conventional floor panel support device in which both the lower surface 100a and the mounting surface 101a are perpendicular to the support bolts 102 is installed on such a floor base surface, the mounting surface 10
1a was inclined, and the floor boards to be supported tended to be inclined.

Further, the floor plate supporting device is configured to adjust the height of the supporting plate by rotating the supporting bolt while supporting the floor plate, but the conventional floor plate supporting device is, as described above, Since the lower surface 100a of the elastic base is a horizontal surface, when the support bolt 102 and the elastic base 100 are connected to each other so that they cannot rotate relative to each other, the support bolt 102 is formed due to frictional resistance between the lower surface 100a of the elastic base and the floor base surface 50. It is difficult to rotate 102. From this point of view, the conventional floor panel supporting apparatus connects the supporting bolt 102 and the elastic base so as to be relatively rotatable.
In addition, it is necessary to provide a member 103 such as a bearing member between the elastic bases 100, so that the cost of the apparatus itself increases.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and has a simple structure of a floor panel supporting device capable of supporting a floor panel horizontally regardless of the level of the floor foundation surface. It is intended to be provided at low cost.

[0007]

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a floor panel support device according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a front view of a floor panel support device according to the present embodiment, and FIG. 2 is a sectional view taken along line XX in FIG.

As shown in the figure, a floor board supporting apparatus 1 according to the present embodiment is configured such that a floor board member 60 is at a desired height from a floor base surface 50.
A cylindrical body 11 having an axially extending through hole, and a floor plate supporting flange 12 extending radially outward from an outer peripheral wall of the body. A floor plate supporting member 10, a position adjusting member 20 having a base 21 having a relatively large diameter and a supporting rod 22 erected substantially vertically upward from the upper surface of the base, and a base adjusting member 20 installed on a floor base surface 50, And a resilient base 30 having a concave portion 31 for receiving the non-rotatably.

The floor plate support member 10 has a female screw formed on the inner peripheral surface of the through hole 11a of the body portion 11. It is preferable that at least a part of the trunk portion 11 of the floor plate supporting member 10 protrude above the upper surface of the flange portion 12. By providing such an upwardly protruding portion, the floor plate 60 can be supported by bringing the side end surfaces of the floor plate 60 into contact with each other.
0 can be prevented from shifting in the horizontal direction. The flange portion 12
Has an appropriate number of through holes 12a communicating the upper surface and the lower surface, so that the floor plate 60 can be fixed through the through holes 12a using nails or the like. The floor plate support member 1
0 can take various dimensions, but considering cost and strength, the diameter D should be 50-100 mm, the height B should be 5-22 mm, and the height C of the upper protruding part of the trunk should be 3-20 mm. Is preferred. Various materials can be applied to the floor panel support member 10, but in consideration of strength and the like, it can be made of FRP or steel.

The support rod 22 of the position adjusting member 20 has a male screw corresponding to the female screw of the through hole formed on the outer peripheral wall, and is screwed to the through hole 11a of the body. Therefore, by rotating only the position adjusting member 20 without rotating the floor plate support member 10, the vertical position of the floor plate support member 10 can be adjusted. A notch 22a is formed on the upper end surface of the support rod 22, and the tip of an instrument such as a driver can be inserted into the notch 22a and rotated. The base 21 is
The diameter is larger than that of the support rod, so that a load is applied to the elastic base 30 with a large area. As the position adjusting member 10, for example, M6 to M
Sixteen hexagon bolts can be used. If the tip of the support bar 22 projects upward from the upper surface of the floor plate after the floor plate is supported, it is necessary to cut the projecting portion.
2 is preferably made of resin. The height of the support bar 22 is preferably such that the height A of the entire floor panel support device is 40 mm to 150 mm in consideration of the height of the floor panel normally installed.

The elastic base 30 has a concave portion 30a formed on the upper surface thereof so as to be fitted with the base of the position adjusting member, and the concave portion 30a supports the base 21 of the position adjusting member so as to be relatively non-rotatable. . Lower surface 31 of elastic base 30
Has a convex shape whose center is located coaxially with the position adjusting member, and has a tapered shape in the present embodiment. The elastic base 30 can be made of various materials, but is preferably made of hard rubber or resin in consideration of soundproofing and earthquake-proofing. The elastic base 30 can have various dimensions, but in consideration of cost and strength, the diameter E is 25 mm to 40 mm, the height F is 20 mm to 40 mm, and the taper angle G is
It is preferable that the angle is 5 ° to 30 °. In order to make the lower surface 31 convex, in addition to the tapered shape as in the present embodiment, a spherical shape as shown in FIG. 3 can be used. In such a case, preferably, the spherical radius R is set to 10
mm to 50 mm.

[0015] The floor plate supporting apparatus constructed as described above has the following effects. That is, since the floor base surface is usually not completely horizontal, if the lower surface of the elastic base is set to be a horizontal plane flush with the support bar, the support bar is tilted according to the tilt of the floor base surface, whereby As a result, the flange is also inclined, so that the floorboard cannot be supported horizontally. On the other hand, according to the floor panel support device according to the present embodiment,
Since the lower surface 31 of the elastic base is tapered, even when the floor base surface is inclined, the support rod 22 can be erected vertically with respect to the base surface, thereby horizontally supporting the floor plate. It becomes possible to do.

Further, by making the lower surface 31 of the elastic base convex, even if the position adjusting member 20 is provided so as not to rotate relative to the elastic base 30, the efficiency of the operation of adjusting the position of the floorboard is not deteriorated. Absent. That is, the conventional floor panel support device is shown in FIG.
As shown in the figure, the lower surface of the elastic base is a flush horizontal surface,
Since the lower surface and the floor base surface are in contact with each other over the entire surface, if the position adjusting member and the elastic base are not allowed to rotate relative to each other, the position is determined by frictional force generated between the elastic base lower surface and the floor base surface. It becomes difficult to rotate the adjustment member. From this point of view, the conventional floor plate supporting apparatus includes a bearing member (reference numeral 103 in FIG. 4) and connects the position adjusting member and the elastic base so as to be relatively rotatable. There was a disadvantage that the cost would rise. On the other hand, in the present embodiment, as described above, since the lower surface 31 of the elastic base is tapered, the contact area between the lower surface 31 of the elastic base and the floor base surface 50 can be reduced, and The frictional force generated between the two when the table rotates can be suppressed. Therefore, even if the two members are not rotatable relative to each other without separately providing a bearing member or the like between the position adjusting member and the elastic base, the position adjusting work efficiency does not deteriorate.

Further, in the present embodiment, as shown in FIGS. 1 and 2, a fixing member for fixing the elastic base to the floor base surface is provided, whereby the inclination of the elastic support device 1 is further increased. Well prevented. Although the fixing member can take various forms, in the present embodiment, the fixing member has a through hole 41 a having a diameter larger than the support rod 22 and smaller than the elastic base 30, and the elastic base 30 is attached to the floor base surface 50. The upper end face 41 pressed against
A hollow member having a vertical cross-section having a lower end surface 42 fixed to the floor base surface 50 by an appropriate member such as a bolt, and a side wall 43 connecting the upper end surface 41 and the lower end surface 42; The lower surface height is slightly lower than the height of the elastic base 30.

[0018]

According to the floor panel supporting apparatus of the present invention, a floor panel supporting member having a through hole with a female thread and having a plate-like member on which a floor panel is placed, a base and a male screw extending upward from the base. A position adjusting member having a support rod with the support rod, an elastic base supporting the base so that the support rod is vertical, and a convex portion whose center is located coaxially with the support rod on the lower surface of the elastic base. Since the support rod and the elastic base are connected to each other so that they cannot rotate relative to each other, the support rod can be easily rotated. Accordingly, there is no need to separately provide a bearing member, and cost reduction can be achieved by reducing the number of parts. In addition, since the lower surface of the elastic base is formed in a convex shape, it is possible to horizontally support the floor plate even when the floor foundation surface is inclined or the like.

Further, the floor plate supporting member is provided with a cylindrical body protruding upward from the plate-like portion, and if the female screw is formed on the inner peripheral surface of the body portion, the floor plate supporting member is prevented from moving in the horizontal direction to prevent the floor plate from moving in the horizontal direction. Can be supported.

Further, if a fixing member for fixing the elastic member to the floor base surface is provided, the floor plate supporting device can be stably installed.
