Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a flooring material having stepped end surfaces.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 13 and FIG. 14, there is known a flooring material in which a plurality of rectangular plate pieces 21 are combined in a goose shape and both end faces are formed into a stepwise joint end face. ing.
The joint end surface is formed in an L shape at both ends of the adjacent rectangular plate pieces 21, 21 by the short side end surface of each plate piece 21 and the side end surface connected to the short side at right angles. The L-shaped end face has a male part 23 on one side and a female part 24 on the other side.

The floor material constructed in this manner is constructed by fitting the male and female portions 23 and 24 formed in a stepped manner to each other and successively adding them onto the floor base material for floor construction. Floor materials that are constructed in the direction perpendicular to the direction of addition are
Since the construction is performed in a state where the side end surfaces on the long side that are parallel to each other are simply joined together, there arises a problem that a gap or a step is generated between these side end surfaces, which makes it difficult to perform accurate construction.

Therefore, the inventors of the present application filed Japanese Patent Application No. 4-31.
No. 7769, as shown in the above figure, a fitting groove of an upward opening having a constant width in which an outer end wall is formed on an upward engaging ridge 29 at a lower end portion of one side end surface on both end surfaces on the long side. In the width direction, a plurality of 30 are provided in a row and a fitting projection edge portion 26 and a locking groove 27 with a downward opening are provided on the other side end surface side so that the fitting groove 30 and the locking projection 29 can be fitted to each other. We have developed a flooring material that prevents misalignment between flooring materials that are joined to each other and does not create gaps or steps.

[0005]

However, when the fitting groove 30 having the locking projections 29 on both side edges and the fitting projection edge portion 26 and the locking groove 27 are formed as described above, the floor materials are not separated from each other. The joining is limited only to the longitudinal direction (longitudinal direction of the rectangular plate piece 21). In this case, the female part of the floor material 24
In contrast, when the male member 23 of the next floor member is fitted with the male member 23 facing diagonally downward, the adjacent rectangular plate pieces 2
In the male and female parts 23 of 1 and 21, the lower surface of the male and male part 23a projecting on the long side is brought into contact with the upper side 24a of the long side, which forms the female part of the floor material that has already been constructed. The material cannot be slid horizontally.

For this reason, the next floor material is placed on the floor base material in a state of being separated from the already installed floor material in the lengthwise direction, and then the floor material is slid to produce male and female fruits. The fitting work of the parts 23 and 24 must be performed, and it is difficult to secure a slidable space when the floor is constructed in a narrow place such as a wall part or a corner part, and the workability is poor. There was a problem. An object of the present invention is to provide a flooring material that can solve such problems.

[0007]

In order to achieve the above object, the flooring material of the present invention comprises a plurality of rectangular plate pieces, which are joined to each other and are joined to each other at the side end surfaces on the opposite long sides. To form a floor material main body that is integrated in a state of being staggered in the length direction, and an outer end wall is formed at the lower end of one side end surface of both side surfaces of the parallel long side of the floor material main body. A fitting protrusion edge portion in which a fitting groove having a constant width formed in an upward opening formed in the locking protrusion is continuously provided, and the fitting groove and the locking protrusion can be fitted to the other side end face side, respectively. And a locking groove with a downward opening,
Furthermore, a male solid portion is formed on one short side end surface of each of the rectangular plate pieces, and a female solid portion into which the male solid portion can be fitted is formed on the other short side end surface of the rectangular plate piece, and they are staggered. In the end portion on one side of the long side of the adjacent rectangular plate piece exposed by, at least a corner portion connected to the male portion at a right angle is formed on the side end surface where the male portion is not provided. ing.

[0008]

When the floor material having the above-mentioned structure is laid on the floor base material, the male material of the floor material to be applied next to the female part of the existing floor material previously attached to the floor base material When the real parts are made to face diagonally downward and the floor material is abutted against the existing floor material in that state, the floor material to be constructed is the side of the corner part that is connected to the male real part at a right angle. Since the edge is formed on a flat side end surface without a male solid portion, the side end surface can be slidably contacted with the side end surface of the existing floor material that is connected at a right angle to the female solid portion, and thus faces downward. The front end of the male part that is inclined to the front has entered the open end of the female part of the existing floor material.

From this state, when the floor material to be constructed is gradually moved in the horizontal direction and pushed toward the existing floor material side, the male part is fitted into the female part, and the floor material is placed on the floor base material. When it comes into close contact with the male part, the male part is completely fitted in the female part. By such a procedure, the floor materials are sequentially joined and constructed along the wall edge portion of the floor base material in the length direction.

Next, in order to sequentially join the floor materials in the width direction, it is necessary to work on the fitting groove of the upward opening having the locking ridge protruding from one end face of the existing floor material. When the floor material is inclined obliquely downward, the fitting projecting edge portion provided on the other side end face side is fitted into the fitting groove, and the floor material is gradually slid from this state so that the other side end. The engaging groove of the downward opening formed on the lower surface of the part is engaged with the engaging ridge of the existing floor material. When the floor materials are sequentially applied in the width direction by this procedure, the fitting between the locking ridges and the locking grooves restrains the movement between the floor materials in the width direction, thereby eliminating the occurrence of a gap.

EXAMPLE Next, an example of the present invention will be described. 1 is a rectangular plate piece having a constant width and a constant length, which is formed of a material such as plywood, particle board, and MDF. A plurality of sheets (four sheets in the figure) are joined to each other, and the opposite side end faces on the longer side are joined together, and are sequentially staggered by a desired dimension in the length direction. The floor material main body A, which is fixed in one piece and has a plane geese shape, is formed.

In each of the short-side end faces of each plate piece 1 forming the flooring main body A, a male solid portion 2 is formed over substantially the entire width at the center portion in the thickness direction of one end face, A female solid portion 3 into which the male solid portion 2 can be fitted is formed over the entire width at the center portion of the other end face in the thickness direction. In addition, the long side edge one side end surface of the adjacent plate pieces 1 and 1 exposed by shifting in a stepwise manner is formed as a smooth side end surface 1a where the male portion 2 is not provided and the floor material is mainly used. In the long side portions of the plate pieces 1 and 1 arranged on the outermost side forming A,
On one plate piece 1 forming one end surface of the floor material main body A, a ridge portion 4 connected to the male portion 2 at a right angle is formed over the entire length, and the other end surface of the floor material main body A is formed. The other plate piece 1 to be formed
In addition, a concave groove 5 that is connected to the female part 3 at a right angle is formed over the entire length. Further, a fitting projection edge portion 6 is formed between the concave groove 5 and the lower surface of the plate piece 1, and a locking groove 7 having a downward opening is formed in the central portion of the lower surface of the plate piece 1 over the entire length. There is.

On the lower surface of the floor material main body A, an elastic lower patch 8 made of rubber, elastic resin sheet or the like having a constant thickness is stuck. The lower adhesive material 8 is attached so that one end thereof is aligned with the inner edge of the locking groove 7 on the lower surface of the flooring material main body A, and the other end is fixed width from the lower surface of the flooring material main body A. A bar-shaped locking projection 9 made of wood or another suitable hard material is fixed to the upper surface of the edge of the base member. A fitting groove 10 having an upward opening with the locking projection 9 as an outer end wall is formed over the entire length between the locking projection 9 and the other end surface of the floor material main body A. . The locking projection 9 and the fitting groove 10 are formed at positions where they can be fitted to the locking groove 7 and the fitting projecting edge portion 6 which are formed at one end of the floor material main body A, respectively. It has been done.

The procedure for applying the floor material thus constructed on the floor base material B will be described. First, as shown in FIGS. When the male material portion 2 side of the floor material to be constructed next is made to face the female material portion 3 side facing downward while facing diagonally downward and the floor material is abutted against the existing floor material in that state, Since the floor material to be formed has the long side one end face formed in a staircase by the adjacent plate pieces 1 and 1 is formed on the vertical side end face 1a not forming the male portion 2, The side end surface 1a can be slidably contacted with the long-side other end surface of the existing floor material that is formed in a stepwise manner, and therefore the tip of the male part 2 inclined downwards can be attached to the existing floor material. It may be in a state of abutting against the open end of the female part 3.

From this state, when the floor material to be constructed is gradually moved in the horizontal direction and pushed toward the existing floor material side, the male real part 2 is fitted into the female real part 3 and the floor material is under the floor. As shown in FIG. 5, the male and female parts 2, 3 are completely fitted when they are attached to the base material and brought into a horizontal state. By such a procedure, the floor materials are sequentially joined and constructed in the length direction along the wall edge portion of the floor base material B. In this state, the fitting groove 10 having the locking projection 9 projecting from the other end of the floor material main body A is continuously provided in a straight line in the length direction. In addition, the floor material for the floor base material B is fixed only by placing it,
