  Therefore, Patent Document 1 proposes several fixing structures. That is, the toilet member and the floor member are fixed with a magnet. Fit with snap pins. Fix with double-sided (adhesive) tape or adhesive. Join with planar fasteners. Alternatively, in combination with the above, a sheet made of a soft synthetic resin or the like that can be contracted flexibly in the thickness direction is interposed.

JP 2005-48584 A

  Although each fixing structure listed in Patent Document 1 has some flexibility at the time of attachment, it cannot sufficiently absorb earthquakes acting on the toilet and repeated vibrations caused by long-term use after the floor surface is attached.

In order to solve the above problems, the present invention is a structure for fixing a flush toilet equipped with a skirt portion to the floor over substantially the entire circumference of the lower part of the toilet body, and a toilet side fixing member is fixed to the inside of the skirt portion. A floor-side fixing member is provided at a position facing the toilet-side fixing member, and the toilet-side fixing member and the floor-side fixing member are deformed by being narrowed between the two members and maintained in the deformed state. It was set as the structure fixed by the soft adhesive material layer which becomes.
By adopting such a configuration, the installation of the flush toilet on the site is simplified, and there is no occurrence of problems such as shifting after installation.

  In this invention, it is preferable to set it as the structure which has an uneven | corrugated shape in the contact surface with the at least one soft adhesive material layer of the said toilet bowl side fixing member and a floor side fixing member. By doing so, the adhesive strength is further increased.

  Further, even when at least one of the toilet-side fixing member and the floor-side fixing member includes a protruding piece portion embedded in the soft adhesive material layer, the fixing strength is further improved.

  As the soft adhesive layer, for example, a polypropylene compound, a room temperature curable adhesive, and the like are suitable. Furthermore, if the toilet-side fixing member and the floor-side fixing member have an arcuate plane that matches the curved shape of the flush toilet, the bonding area is increased and the fixing strength is improved.

  According to the floor fixing structure of the flush toilet according to the present invention, the toilet side fixing member and the floor side fixing member are adhered and fixed via the soft adhesive layer, so that the floor surface is in the vertical direction, Even when a parallel force is applied, it is possible to maintain the connection with flexibility. Therefore, there is no worry that a load is applied to the flush toilet body.

  Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a side sectional view showing an example of a floor fixing structure of a flush toilet according to the present invention, FIG. 2 (a) is a partial sectional view before installation of the floor fixing structure of FIG. 1, and (b) is a floor fixing of FIG. It is a fragmentary sectional view after structure installation.

  The outer periphery of the flush toilet 1 is covered with a skirt portion 2. A skirt support wall 3 is provided inside the skirt portion 2 to withstand a load applied from the bowl surface 4 side.

  A toilet-side fixing member 5 according to the present invention is fixed to the skirt support wall 3 by two fixing bolts 6 and 6. The two fixing bolts 6 are fixed by, for example, turn nuts or well nuts that do not need to be tightened from the back side.

  The toilet-side fixing member 5 is fixed to a floor-side fixing member 9 installed on the floor surface 8 with a fixing bolt 10 via a soft adhesive layer 7. In order to connect the toilet-side fixing member 5 and the floor-side fixing member 9, as shown in FIG. 2A, the soft adhesive material a <b> 1 is placed on the floor-side fixing member 9. At this time, an enclosure 9a is provided at the upper part of the floor-side fixing member 9 so that the soft adhesive material a1 is not crushed when it is crushed and the soft adhesive material a1 does not protrude from the floor 8. It is preferable.

  The soft adhesive material a1 used in the present invention can be deformed so as to fill the gap between the toilet-side fixing member 5 and the floor-side fixing member 9 and perform adhesive fixing, and can hold the deformed shape for a long time. Anything can be used.

  Examples of such soft adhesive material a1 include plastic clay and plastic compound, among which plastic compound, especially polypropylene compound is preferable. Polypropylene compounds are obtained by kneading synthetic rubber, inorganic fillers, and other materials into polypropylene resin, and are commercially available. If a polypropylene compound is used as the soft adhesive material a1, it can be easily deformed by pressure, and it is easy to hold the deformed shape without contraction or deterioration.

  FIG. 2B shows a floor fixing structure in which the flush toilet 1 is lowered toward the floor surface 8 and the toilet side fixing member 5 and the floor side fixing member 9 are connected, and the toilet side fixing member 5 and the floor side fixing are shown. Since the member 9 is adhered and fixed via the soft adhesive layer 7 formed of the soft adhesive material a1, it is flexible even when a vertical or parallel force is applied to the floor surface 8. It is possible to maintain a connection with each other. Therefore, there is no worry that a load is applied to the main body of the flush toilet 1.

  FIG. 3 is a side sectional view showing another example of the floor fixing structure of the flush toilet of the present invention. The figure (a) is a fragmentary sectional view which shows the state before floor fixing. In this example, the upper surface 9b of the floor-side fixing member 9 has an uneven shape. By making the upper surface 9b concavo-convex, when the soft adhesive material a1 placed on the upper surface 9b is crushed, the contact area between the upper surface 9b and the soft adhesive material a1 is increased, and the adhesiveness is increased. On the other hand, there is an advantage that the shift in the parallel direction can be suppressed.

  FIG. 2B shows an enlarged view of the concavo-convex shape of the upper surface 9b. There is no particular limitation on the type of the concavo-convex shape, and examples thereof include a protruding group, a lattice shape, and other pattern shape groups.

  FIG. 3C is a partial cross-sectional view after the floor is fixed. In this example, the top surface 9b of the floor-side fixing member 9 is provided with a concavo-convex shape. Conversely, a similar concavo-convex shape may be provided on the contact surface of the toilet-side fixing member 5 with the adhesive material layer 9. Furthermore, formation of irregularities on both the contact surface and the upper surface 9b is most recommended.

  The position of the fixing bolt 10 shown in the figure is different from that shown in FIG. 2 and is provided in the vicinity of the end of the floor-side fixing member 9, but such a fixing bolt 10 and the floor-side fixing member are provided. The relative position with respect to 9 is not limited, and can be appropriately selected in consideration of the structure of the attachment place and the structure of the flush toilet 1 itself to be attached.

  FIG. 4 is a side cross-sectional view showing another example of the floor fixing structure of the flush toilet of the present invention. The figure (a) is a fragmentary sectional view which shows the state before floor fixing. In this example, the space formed by the enclosure 9a of the floor-side fixing member 9 is used as a fixing material accommodating portion. The fixing material storage portion stores the room temperature curable adhesive a2 or the pressure sensitive adhesive a2. Examples of such adhesives and pressure-sensitive adhesives include one-component curable and two-component curable polyurethane-based, epoxy-based, synthetic rubber-based adhesives, and pressure-sensitive adhesives. The room temperature curing type is not particularly limited as long as it can form a soft soft adhesive layer 7 such as moisture curing, catalyst curing, energy ray curing, and the like, and is appropriately determined in consideration of the installation location of the flush toilet 1. You can choose.

  Another feature of this example is that a protruding piece 5a is provided at the bottom of the toilet-side fixing member 5. As shown in the partial cross-sectional view after fixing the floor in FIG. 5B, the protruding piece 5a is used by being buried in the pressure-sensitive adhesive layer 7 formed by the adhesive a2 or the pressure-sensitive adhesive a2. It is preferable to harden the adhesive a2 or the adhesive a2 after the protrusion piece 5a is buried, because the adhesion between the toilet-side fixing member 5 and the floor-side fixing member 9 is increased.

  4 shows an example in which the protruding piece 5a is buried in the adhesive layer 7 formed of the adhesive a2 or the adhesive a2, the protruding piece 5a is made of soft adhesive such as the above-described polypropylene compound. It is also possible to embed it in the pressure-sensitive adhesive layer 7 formed of a material by sharpening the tip of the protruding piece portion 5a.

  FIG. 5 is a plan view showing an example of shapes of the toilet side fixing member and the floor side fixing member. In the conventional example, as shown in FIG. 7A, the floor surface fixing member 104 is fixed to the floor surface by two fixing bolts 103a and 103a. On the other hand, in this example, both the toilet-side fixing member 5 and the floor-side fixing member 9 have an arcuate plane that matches the curved shape of the skirt portion 2 of the flush toilet 1. By adopting such an arcuate plane, a wide contact area between the toilet-side fixing member 5 and the floor-side fixing member 9 can be secured, so that the stability of the floor fixing structure of the present invention can be enhanced.
