[Detailed description of the invention]

[0001]

The present invention provides a receiving member for receiving a supported portion of a floor panel juxtaposed in a floating floor surface, a supporting leg for supporting the receiving member, and the mounting member mounted on the receiving member. The present invention relates to a floating floor supporting device provided with a fixing mechanism for pressing and fixing a floor panel to a panel mounting portion of the receiving member.

[0002]

2. Description of the Related Art Conventionally, as a floating floor support device of this kind, a male screw member and a female screw member which can be screwed to each other are provided.
The female screw member is provided on a receiving member that receives a supported portion of the floor panel, the male screw member is provided with a contact portion with the upper surface of the floor panel, and the male screw member is screwed to the female screw member. The floor panel between the contact portion and the panel mounting portion of the receiving member by further tightening in a state where the contact portion is in contact with the upper surface of the floor panel. There was something that pinched and fixed.

[0003]

According to the above-mentioned conventional floating floor support device, the floor panel is fixed to the receiving member by fitting the male screw member and the female screw member. If, for example, vibration is applied to the panel, there is a danger that the screw fitting portion will loosen due to the vibration, and the floor panel will be incompletely fixed, or the floor panel will rattle. is there.

Further, in tightening the screw member, it is necessary to rotate the screw member around the axis many times, and there is a problem that it takes time to fix the panel. To solve this problem, the pitch of the screw is reduced. If it is increased, the number of rotations associated with the tightening can be reduced, but a new problem arises in that it becomes easier to loosen.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above-mentioned problems and to provide a floating-floor support device which can easily and speedily fix a floor panel to a receiving member and is hard to be loosened.

[0006]

In order to achieve this object, a floating floor support device according to the present invention is characterized in that a receiving member for receiving a supported portion of a floor panel juxtaposed in a floating floor surface is provided. In a floating floor supporting apparatus provided with a supporting leg for supporting a member and a fixing mechanism for pressing and fixing the floor panel mounted on the receiving member to a panel mounting portion of the receiving member, the fixing mechanism is configured. A first fitting portion and a second fitting portion that can be fitted to each other, one of the first and second fitting portions is provided on the receiving member, and the other is a contact portion for the upper surface of the floor panel. Is provided, and a projection is provided on one of the fitting surfaces of the first and second fitting portions, and a locking portion is provided on the other, which can lock with the projection and prevent the two fitting portions from separating. Arranging the locking portion spirally along the fitting surface, The旋終end, the locking portion screwed in starting side
There is a slope with a slope opposite to the slope .

[0007]

According to the features of the floating floor support device of the present invention.
If so, the protrusion is formed by the fitting between the first fitting portion and the second fitting portion.
The helical locking part is locked, and the shaft center circumference of both fitting parts is locked.
The first and second fitting parts are close to each other
Can be deepened in the direction in which
The contact portion contacts the upper surface of the placed floor panel,
The floor panel can be pressed against the receiving member.

[0008] In its, fitting spiral end of the projection and the locking portion
To reach the spiral slope and the opposite slope
By the reaction force of the floor panel
Is guided to the end side of the slope having the reverse slope, resistance to relative rotation of the projection to the release side is given, and the floor panel is used for floating floor in a state where the first fitting portion and the second fitting portion are locked. It is possible to stably fix to the support device.

This operation will be described with reference to an example of a floating floor supporting device shown in FIG. 1. A first fitting portion 8 is provided on the receiving member 3, and a projection 8a is provided on the outer peripheral surface of the first fitting portion 8. A second fitting portion 11 having a spiral engaging portion 16 engaged with the projection 8a formed on an inner peripheral surface is provided, and a flange-shaped contact portion 15 is provided on an outer periphery of an upper end side of the second fitting portion 11. , A supporting device A provided with a leaf spring washer 12 between the contact portion 15 and the upper surface of the floor panel 2
, The plurality of floor panels 2 placed on the receiving member 3
When the second fitting portion 11 is externally fitted so that the locking portion 16 is locked to the projection 8a of the first fitting portion 8 disposed therebetween, and is rotated around the axis P, the second fitting portion The portion 11 is guided in a state in which the engaging portion 16 slides on the protrusion 8a and approaches the receiving member 3 side, and the contact portion 15 is connected to the floor panel 2 via the washer 12.
The upper surface is brought into contact with and pressed.

Further, when the second fitting portion 11 is rotated, the slope is over the lock release prevention portion 19 provided with the spiral locking portion 16 and the slope 17 formed on the slope having the opposite slope. Part 18
The projection 8a moves over the slope 17 and comes into contact with the end of the locking portion 16.

In this state, the lock release prevention portion 19 of the second fitting portion 11 is pressed against the lower surface of the projection 8a by the elastic restoring force of the washer 12, and the first fitting portion 8 causes the shaft center to be released. The rotation around P is prevented from coming off, and the floor panel 2 is locked, and the floor panel 2 can be securely fixed.

In this locked state, the reaction force against the tightening force always acts as a force for deepening the fitting of the two fitting portions 8 and 11, so that it is possible to prevent the loosening due to vibration as in the prior art.

Further, if the spiral gradient of the locking portion 16 is formed to be steep, the second fitting portion 11 can quickly approach the receiving member 3 as the second fitting portion 11 rotates around the axis P. As a result, the locked state can be achieved without rotating the second fitting portion 11 many times, and the floor panel 2 can be fixed quickly.

[0014]

Therefore, according to the floating floor support device of the present invention, it is possible to reliably and speedily support the floor panel with a simple operation, and to improve the installation efficiency of the device, and to improve the floor work after the support. The panel can be improved in quality without rattling.
