BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support leg for a floor material which is constructed in a state of being separated from a floor base.

[0002]

2. Description of the Related Art Conventionally, when supporting a floor material with a support leg projecting from an appropriate place on the lower surface of the floor material, as shown in FIG. -Like cushion receiver 3 is provided, and this cushion receiver 3 is placed on the floor base 4.
The cushion body 5 is adapted to be fitted on the upper part of the above so as to absorb vibrations and impacts applied to the support leg body 2.

[0003]

By the way, in cushioning the vibration and impact applied to the floor material 1, in order to improve the vibration damping effect, the material of the cushion body 5 is a material having a high vibration damping effect (a large loss coefficient). For example, it is conceivable to use low-repulsion rubber such as hanenite or sorbosein or to reduce the spring constant. However, if the cushion body 5 is made of a material having a large elastic deformation rate in order to increase the vibration damping effect, the vibration damping effect is improved. The subduction is large, and the subduction of the floor material is large. If the cushion body 5 is made of a material having a small elastic deformation rate in order to prevent the floor material 1 from sinking, the floor material 1 is prevented from sinking to some extent. There is a problem that the effect becomes small.

The present invention is intended to solve the above problems, and an object thereof is to provide a supporting leg for a floor material having a high vibration damping effect while preventing the floor material from sinking.

[0005]

According to the present invention, in order to achieve the above object, a supporting leg main body 2 is provided so as to project downward from a proper place on the lower surface of a flooring 1 and is provided at a lower portion of the supporting leg main body 2. A cushion receiver 3 having a U-shaped cross section with an open lower surface is fitted on the upper portion of the cushion body 5 placed on the floor base 4, and when the cushion receiver 3 descends on the outer surface of the cushion body 5, the cushion receiver 3 A step portion 6 for preventing depression is formed on which the lower end of the cushion is placed, and a support protrusion 7 protruding below the inner surface of the cushion receiver 3 is inserted into a recess 8 formed in the upper portion of the cushion body 5. Then, at the bottom of the cushion body 5, a void portion a
And a thin portion 9 is provided at the bottom of the recess 8 in which the supporting projection 7 is placed.

[0006]

The relatively small vibration transmitted from the floor material 1 to the support leg body 2 is propagated to the thin wall portion 9 from the support protrusion 7 of the cushion receiver 3 and is alleviated by the thin wall portion 9. In addition, when a large load is applied, the cushion receiver 3 descends and the lower end of the cushion receiver 3 hits the depression preventing step portion 6 of the cushion body 5, so that the depression is stopped and a large depression occurs. To be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments. The support legs are for allowing the floor material 1 to be installed in a state of being floated above the floor base 4,
The floor material 1 is provided so as to project downward from a proper place on the lower surface thereof. The support leg is configured such that the cushion body 5 and the cushion receiver 3 are provided below the support leg main body 2, and the cushion body 5 and the cushion receiver 3 reduce the vibration transmitted from the floor material 1 to the support leg main body 2. It is like this. A screw portion 2a is provided on the upper portion of the support leg main body 2, and the screw portion 2a is screwed to a panel receiver 11 fixed to the lower surface of the flooring material 1 by a fixing tool 10 so that the height can be freely adjusted. ing. Cushion holder 3 attached to the lower end of the support leg body 2
Has a U-shaped cross section with an open lower surface, and a supporting projection 7 is provided in the interior so as to project downward. The supporting projection 7 is inserted into a recess 8 of a cushion body 5 described later. At the same time, it is fitted on the upper portion of the cushion body 5 so as to be connected and integrated with the cushion body 5. The cushion body 5 is formed of an elastic body such as a rubber cushion, and a recess 8 into which the support protrusion 7 of the cushion receiver 3 is inserted is provided in the upper portion. The cushion body 5 has an upper outer surface having a smaller diameter than that of the lower outer surface, and when the cushion receiver 3 fitted on the outer surface is lowered, the lower end of the cushion receiver 3 is placed, and the step portion 6 for preventing depression is placed. Are formed. here,
The lower end of the cushion receiver 3 fitted on the upper part of the cushion body 5 and the sinking prevention step 6 are normally separated from each other (when no load is applied to the floor material), and the lower end of the cushion receiver 3 is A gap 12 is formed between the submergence prevention step portion 6 and the subduction prevention step portion 6. Cushion body 5
A void portion a is provided at the bottom of the concave portion 8 and the thin portion 9 is formed at the bottom of the recess 8 by the void portion a.

The vibration transmitted from the floor material 1 to the support leg is transmitted from the cushion receiver 3 to the cushion body 5, but is not mitigated by the cushion body 5 and is not transmitted to the floor base 4. There is. Here, the vibration transmitted from the cushion receiver 3 to the cushion body 5 is transmitted to the cushion body 5 from the support projection 7 inserted in the concave portion 8, but is formed in the bottom portion of the concave portion 8 by the void portion a. Since the thin portion 9 is present, the thin portion 9 is elastically deformed, so that a relatively small vibration is alleviated. In addition, when a large load is applied to the floor material 1, the cushion leg 3 is lowered together with the support leg main body 2 and the lower end of the cushion leg 3 hits the depression preventing step portion 6 so that the cushion leg 3 sinks. As a result, the floor material 1 is prevented from largely sinking. That is, with respect to vibration such as a small load or impact, the elasticity of the thin portion 9 lowers the support leg body 2 and the cushion receiver 3 to alleviate the vibration.
With respect to a large load, impact, etc., the cushion receiver 3 does not descend more than a certain amount, so that the sinking is prevented, so that the vibration damping effect can be enhanced while preventing the sinking of the flooring 1. . Also, the support protrusion 7
Since the cushion receiver 3 is attached to the concave portion 8 and the cushion receiver 3 is attached to the cushion body 5, it is possible to prevent lateral displacement of the cushion body 5 when vibration is applied.
The cushion receiver 3 can be securely attached to the.

FIG. 6 shows the sinking amount of the floor material 1 with respect to the load applied on the floor material 1. That is, in a state where there is no gap between the depression-preventing step 6 and the lower end of the cushion receiver 3 (a state where the lower end of the cushion receiver hits the depression-preventing step), the solid line of the present invention is shown. It is understood that the floor material has a smaller subsidence of the floor material than the conventional one indicated by the broken line.

FIG. 3 shows another embodiment of the present invention. In this embodiment, the side surface portion of the cushion body 5 is cut out at regular intervals to provide cutouts 13. The notch 13 reduces the contact area with the cushion receiver 3 to reduce the contact resistance when the cushion receiver 3 moves. FIGS. 4 and 5 show still another embodiment, in which a protrusion 15 is provided in the upper portion of the cushion body 5 by means of a groove 14 or a notch, and a contact area with the cushion receiver 3 is shown. And the elastic coefficient of the upper portion of the cushion body 5 is reduced to improve the vibration damping effect.

[0011]

As described above, the present invention has a cushion having a U-shaped cross section in which the supporting leg main body is provided so as to project downward from an appropriate position on the lower surface of the floor material, and the lower surface of the supporting leg main body is opened. The receiver is fitted on the upper portion of the cushion body placed on the floor base, and a step portion for preventing depression is formed on the outer surface of the cushion body on which the lower end of the cushion receiver is placed when the cushion receiver is lowered, A support projection protruding downward from the inner surface of the cushion receiver is inserted into a recess recessed in the upper portion of the cushion body, and a cavity is provided in the bottom of the cushion body to mount the support projection. Since a thin portion is provided at the bottom of the, the vibration transmitted from the support leg body to the cushion body is alleviated by elastic deformation of the thin portion formed at the bottom of the recess, and a large load. Was added to the floor material In this case, the cushion receiver goes down together with the support leg body, and the lower end of the cushion receiver hits the step-prevention step, which prevents the sinking of the cushion receiver and prevents the floor material from greatly sinking. For vibrations such as small loads and shocks, the elasticity of the thin wall part lowers the cushion receiver together with the support leg body, so that the vibrations are alleviated. Since the sinking is prevented by not descending, the vibration damping effect can be enhanced while preventing the sinking of the floor material. Also, since the support protrusion is inserted into the recess to attach the cushion receiver to the cushion body, it is possible to prevent lateral displacement of the cushion body when vibration is applied, and to attach the cushion receiver to the cushion body. Can be ensured.
