Description

  The flooring according to the present invention is a type of flooring that actually bonds adjacent flooring when laid, and particularly relates to a flooring that can be easily constructed without necessarily fixing the flooring to the floor base material. .

  The floor material laid on the floor base material changes the moisture content of the floor material after laying, due to changes in the temperature and humidity of the surrounding environment, or by wiping the floor material with a wet cloth, and as a result, the floor material expands and contracts. As a result, when the flooring is extended, the contact boundary between adjacent floors rises and hinders walking and cleaning.When the flooring shrinks, there is a gap at the contact boundary between the flooring. As a result, there were problems such as difficulty in walking and accumulation of dust in the gaps, which was unsanitary.

  On the other hand, in the floor material of the type in which adjacent floor materials are actually bonded, shrinkage and expansion due to the change in the moisture content of the floor material cannot be sufficiently suppressed by the actual bonding. Conventionally, in the case of a floor material that is actually bonded, in order to suppress the shrinkage and expansion of the floor material, the floor material is nail-fixed to the floor base material, or an adhesive is applied to the contact surface between the male fruit and the female fruit. The measure of using was taken. However, this control means has a problem that it takes time to lay the flooring and the laying cost is high.

  In addition, when the floor material is laid in an actual connection without being fixed to the floor base material, when a vertical step is generated on the contact boundary surface due to the expansion of the adjacent floor material, the generation of the step is suppressed. However, the resistance force when the adjacent floor materials shrink and try to leave each other is hardly seen unless the male fruit and the female fruit are fixed with an adhesive or the like.

  As a method for preventing the adjacent floor materials from being separated from each other without fixing the floor material to the floor base material, the adjacent floor materials are engaged with each other in FIG. 11 of JP-A-2006-328840. A configuration is disclosed.

  This snap-fitting floor material joining method forms a female fruit opening downward at the end of one floor material, forms a male fruit protruding upward at the edge of the other floor material, The other floor material is also moved from the upper side to the lower side toward the male fruit and actually joined, and even in the actually joined state, there is a gap between the female fruit and the male fruit. There was horizontal shaking between the two. Therefore, even in this snap-fit type floor material joining method, the resistance force when the adjacent floor materials shrink and try to separate from each other was hardly present until a slight gap was generated between the floor materials.

In addition, the floor material coupling method described in Patent Document 1 is only the actual coupling that fits in the vertical direction by the snap fit method, and the actual coupling that fits in the horizontal direction is not adopted at the same time. When the flooring material expands, there is a problem that the contact boundary surface is likely to be raised, and a vertical step is likely to occur on the contact boundary surface.
JP 2006-328840 A (FIG. 11)

  The flooring of the present invention is made in view of the above background art, and it is not always necessary to fix the flooring to be laid to the floor base using a nail, an adhesive, an adhesive tape, etc. Even if the floor base material is not fixed to the floor base material, it effectively suppresses the expansion and contraction of the floor material that tends to shrink and expand with the change in the moisture content of the floor material, and the contact boundary surface between the floor materials rises to Eliminates problems such as troubles in cleaning, and when flooring shrinks, there is a gap in the contact boundary between the flooring, making it difficult to walk, and garbage collecting in the gap and unsanitary, Since it is not always necessary to fix the floor material to the floor base material, an object of the present invention is to provide a floor material that can be easily and inexpensively laid.

In order to solve the above problems, a flooring according to the invention of claim 1 is a flooring comprising a surface layer material and a plastic base member adhered to the back surface of the surface layer material, the surface layer material A female seed is formed on each female end face of the adjacent two side end faces, and a male seed is formed on each male end face of the remaining two side end faces. A taper is formed toward the upper end of the tip, and a base member located at the lower part of the female fruit is extended outward from the end face for the female fruit part to form a counter-boring lower piece. An upwardly facing female fruit which is an upwardly opening groove and in which the inner space of the groove can be elastically expanded / contracted, and further, on the base member positioned below the male fruit, The upper part of the upper part of the tailored upper piece is also formed, and the head is When the plurality of flooring materials are laid adjacent to each other, the female fruit and the male fruit are actually coupled and the downward male fruit is elastically applied to the upward female fruit. The mating lower piece and the mating upper piece are made of an elastic body, and the male end face is in contact with the female end face, The protruding height of the male fruit from the end face for the male part is regulated to such an extent that the fruit can be forcedly fitted to the female fruit upward .

  The invention according to claim 2 of the present application is the floor material according to claim 1, wherein the interior of the floor below the groove is compared with the opening width of the groove that forms the upward female seed formed on the upper surface of the counterboring lower piece. When the width of the space is increased and the width of the head of the downward male is larger than the width of the opening, and the floor material is adjacently laid and the downward male is fitted to the upward female, the internal space The width of the head is formed to a width that allows the head to elastically contact the inner wall.

  In the flooring according to the invention of claim 1 of the present application, the flooring is composed of a surface layer material and a plastic base member, and the surface layer material is formed with a female fruit on the end surface for the female body part, An abutment boundary surface of the adjacently laid floor material is formed by forming a male fruit on the end surface for the male part and actually connecting the female fruit of one floor material laid adjacent to the male fruit of the other floor material. In the meantime, it is possible to suppress the occurrence of bulges and steps in the base, and on the other hand, on the base member, a lower piece and an upper piece are formed together with an upward female body formed on the lower piece. Adjacent laying is performed by actually connecting the downward facing male and female formed on the upper piece of the mating and suppressing the horizontal separation of the contact boundary surface of the adjacent laying floor material by the actual coupling. The contact boundary surface of the floor material thus made is less likely to be displaced and deformed both vertically and horizontally.

  In addition, since the downwardly facing male fruit having a head at the lower end is elastically fitted to the upwardly facing female fruit, the space between the internal space constituting the upward female fruit and the downwardly facing male fruit head is It will be elastically contacted in the horizontal direction with no gap, and displacement deformation will not easily occur in the horizontal direction of the floor material laid adjacently, and even if it is temporarily elastically deformed, it will be quickly restored.

  Further, immediately before the female fruit and the male fruit are actually coupled, the internal space forming the upward female fruit can be elastically expanded and contracted, and the downward male fruit 34 has elasticity. The downward facing males and the males can be fitted in a state of being elastically deformed with each other. Therefore, the actual coupling work between the females and the males becomes easy.

Further, when the female fruit and the male fruit are actually coupled in a fitting state in which the upward female fruit and the downward male fruit are elastically deformed with each other, a complicated reaction force is applied to the actual coupling part. Since the taper is formed toward the upper end of the male body from the top of the male body, the actual joining operation for inserting the male body into the female body in a state where the male body portion is pressed downward is further facilitated. In particular, the mating lower piece and the mating upper piece are made of an elastic body, and the male end face is forced to face the female end part with the male end face in contact with the female end face. Since the protruding height of the male body from the end surface for the male body portion is regulated to such an extent that the male body can be fitted, the forced mating of the downward male body and the upward female body can be performed smoothly and smoothly.

  In the flooring according to the second aspect of the present invention, in particular, the width of the inner space below the groove is made larger than the opening width of the groove forming the upward female fruit, and the head of the downward male fruit is formed. The width of the head is made larger than the opening width, and the width of the head is formed so that the head is elastically contacted with the inner wall of the internal space when the downward facing male is fitted to the upward facing female. In addition, it is difficult for the downwardly facing male fruit to be separated from the upwardly facing female fruit, and the horizontal direction between the two is elastically contacted with no gap, and the displacement deformation is unlikely to occur in the horizontal direction of the adjacent laying floor material as well. Even if it is elastically deformed, it quickly recovers.

  FIG. 1 is a partially omitted sectional view showing an embodiment of a flooring of the present invention. In the figure, reference numeral 1 denotes a floor material, and the floor material 1 includes a surface layer material 2 and a plastic base member 3 adhered to the back surface of the surface layer material 2. The adjacent two-side end surfaces of the surface layer material 2 are used as female end portions 21, and the remaining two end surfaces are used as male end portions 23. A female groove 22 having a square groove shape is formed along the longitudinal direction of the end surface 21 for female body. An end surface 23 for the male part is formed with an angular protrusion-shaped male fruit 24 along its longitudinal direction, and a taper 25 is formed from the bottom surface of the male fruit 24 toward the upper end of the male fruit 24. ing. When the floor material 1 is laid, the tip of the taper 25 is easily introduced into the female fruit 22 when the male fruit 24 is fitted into the female fruit 22.

  In the male seed 24, the height from the male part end face 23 to the front end face 241 is regulated to a projecting height d of 0.5 mm to 2.0 mm. A portion is inserted into the female seed 22.

  The material of the surface layer material 2 is, for example, a wooden substrate such as a laminated plywood. However, it may be composed of a single wood board, and various conventionally known wood boards such as particle boards and high-density fiber boards can be used arbitrarily.

  Furthermore, the surface layer material 2 is made of, for example, an inorganic base material such as ceramic or concrete board, a thermoplastic resin obtained by adding wood powder to a thermoplastic resin such as polypropylene resin, or a polypropylene resin. It is also possible to use a profile-extruded molded body obtained by adding wood powder and a foaming agent and foaming the inside thereof, or a synthetic resin base material such as fiber reinforced plastic (FRP). Resin tiles may also be used.

  The base member 3 is made of a relatively soft plastic and is adhered to the back surface of the surface layer material 2 with an adhesive or by simultaneous molding. The base member 3 has a portion positioned below the female fruit 22 extending outward from the female real part end face 21 to form a counter-boring lower piece 31. An upwardly facing female fruit 32 is formed on the upper surface. The upward female fruit 32 is a groove that opens upward, and an internal space 321 of the groove can be elastically expanded and contracted. Further, the width b of the internal space 321 below the groove is made larger than the opening width a of the groove forming the upward female body 32.

  Further, the base member 3 is formed with an upper portion 33 of a mating portion in which a portion located below the male portion 24 is retracted from the end surface 21 for the male portion, and is formed on the lower surface of the upper portion 33 of the mating portion. A downwardly facing male fruit 34 is formed. The downwardly facing male fruit 34 is provided with a head 35 having elasticity at its lower end, the head 35 is bifurcated downward, and the width c of the head 35 forms the upwardly facing female fruit 32. It is larger than the opening width a of the groove, and is slightly larger than the width b of the internal space 321 below the groove.

  Since the downwardly facing male fruit 34 has elasticity and the head 35 has a bifurcated shape downward, when the downwardly facing male fruit 34 is fitted into the upwardly facing female fruit 32, the head 35 is elastic. Then, while narrowing the width c, it passes through the opening width a of the upwardly facing female fruit 32 and elastically fits into the internal space 321, and then the head 35 is elastically restored and elastically contacts the inner wall of the internal space 321. At this time, the internal space 321 is also elastically expanded moderately.

  FIG. 2 is a partial cross-sectional view showing a floor material joining portion when a plurality of the floor materials are laid adjacent to each other, and FIG. 3 is a partial cross-sectional view showing a state immediately before the floor material joining when a plurality of the floor materials are laid adjacent to each other. is there. The flooring laying order of the present invention is as follows. First, the downwardly facing male fruit 34 is elastically forcibly fitted to the upwardly facing female fruit 32, and then one flooring 1 is shifted in the horizontal direction so that the female fruit 22 and the male fruit 24 Are fitted.

  Next, the floor laying procedure will be described in more detail. Floor material 1 (FIG. 2 and FIG. 2) to be laid on the upward facing female 32, which has already been laid (left floor material in FIGS. 2 and 3; hereinafter referred to as “left floor material” for convenience). In order to forcibly and downwardly fit the downward facing male body 34 (hereinafter referred to as “right side flooring” for the sake of convenience), the front end surface 241 of the male body 24 of the right side flooring 1 is first placed on the left side flooring 1. When the right floor material 1 is moved downward in a state where it is in contact with the female real part end surface 21 above the female real 22, a part of the lower end portion of the head 35 of the downward male fruit 34 is formed. A part of the upwardly facing female fruit 32 abuts on the right side by a protruding height d of the male fruit 24. At this time, since the protruding height d of the male fruit 24 is regulated to such an extent that the downward male fruit 34 can be forcibly fitted to the upward female fruit 32, the right flooring 1 is further pushed downward. As shown in FIG. 3, the downward male fruit 34 is fitted into the upward female fruit 32 in a state of being elastically deformed with each other.

  In this state, as shown in FIG. 3, the male fruit 24 is opposed to the female fruit 22 in the left-right direction. Therefore, when the right flooring 1 is moved leftward by the protruding height d of the male fruit 24, The male fruit 24 and the female fruit 22 are fitted. At this time, since the taper 25 is formed from the lower surface base portion of the male fruit 24 toward the upper end of the male fruit 24, the male fruit 24 is smoothly introduced into the female fruit 22. 22 can be avoided.

  When the male fruit 24 is fitted to the female fruit 22, the upward female fruit 32 and the downward male fruit 34 are elastically restored, and the both are elastically fitted in a state of facing each other in the vertical direction. This state is shown in FIG. At this time, since the width c of the head 35 of the downward male fruit 34 is larger than the width b of the internal space 321 of the upward female 32, the head 35 is firmly elastically in contact with the inner wall surface of the internal space 321. The actual bond is stabilized.

  If the base member 3 is made of a relatively soft plastic, when the flooring 1 is laid on the floor base material, the base member 3 absorbs unevenness of the floor base material well. The upward female fruit 32 and the downward male fruit 34 can be easily fitted, and particularly when the male fruit 24 is fitted to the female fruit 22 after the upward female fruit 32 and the downward male fruit 34 are forcibly fitted. Since the male member 24 is fitted to the female fruit 22 via the taper 25 in a state in which the base member 3 absorbs the unevenness of the floor base material, some dimensional errors and some unevenness in the actual coupling portion. Even if there exists, the actual connection work becomes easy.

  As described above, when the flooring material of the present application is laid, the adjacent flooring materials 1 and 1 have actual connecting portions in two directions, the vertical direction and the horizontal direction. Even if it does not adhere to the flooring material, the shrinkage and expansion associated with the moisture content change of the flooring material can be well suppressed, and the contact boundary between the flooring materials rises, hindering walking and cleaning. Thus, it is possible to reduce problems such as difficulty in walking and accumulation of dust in the gaps and unsanitary conditions.
