Description

Floor material

The present invention relates to a flooring material having a male fruit portion having a ridge on one side surface in at least one direction and a female fruit portion having a shape capable of engaging with the male fruit portion on the other side surface.

Various conventional flooring materials of this type have been proposed in which a gap is formed when the ridges of the male part are accommodated in the groove space of the female part and joined (see, for example, Patent Document 1). Specifically, in Patent Document 1, the convex stripes of the male real part are tapered toward the tip, so that the convexity of the bottom side (back side) of the groove space of the female real part is convex in the joined state. A gap is formed at the bottom of the strip.

Further, in Patent Document 1, the lower surface of the ridge and the lower protruding ridge on the lower side of the female body portion have a concavo-convex shape that allows them to engage with each other between the upper and lower sides, and even in this engaging structure, there is a gap. Is formed.

With a plurality of gaps in various parts of the male and female parts, that is, a margin for joining, smooth engagement and joining work between the male and female parts is performed between the floor materials. be able to. In particular, since there is a margin on the back side of the groove space and the lower protruding line on the lower side of the groove space protrudes larger than the upper protruding line and the upper side is open, the floor material to be installed is slanted and the convex line is opened. Can be inserted into the groove space and then mounted while being rotated (see FIG. 6 and the like in Patent Document 1).

JP 2001-323644

However, in Patent Document 1, the thickness of the ridge on the base side roughly matches the vertical dimension of the opening of the groove space of the female real part. That is, there is almost no dimensional allowance between the upper and lower parts of the groove space. Therefore, if the protrusion amount of the ridge is increased, it is difficult to engage the ridge and the groove space by the rotation operation even if the upper protrusion on the upper side of the groove space is formed short as in Patent Document 1. Become. Since the amount of protrusion of the ridges cannot be increased in this way, it cannot be expected that the coupling force in the vertical direction will be greatly improved.

Further, in Patent Document 1, the gap in the upper and lower engaging structure between the convex strip and the downward protruding strip is a marginal space for joining work as described above, but the gap space is horizontal after joining the floor materials to each other. There is a risk of directional deviation.

The present invention has been proposed in consideration of such circumstances, and an object of the present invention is to provide a floor material capable of smoothly performing joining work between floor materials and firmly joining floor materials without deviation. To do.

In order to achieve the above object, the floor material of the present invention has a male real portion having a ridge on one side surface in at least one direction, and a groove space having a shape capable of engaging with the ridge on the other side surface. In the floor material having the female part having the above, the female part is provided with an upper protruding strip on the upper side of the groove space, and protrudes laterally from the upper protruding strip on the lower side of the groove space. The groove space includes an arrangement space in which the ridges are accommodated and arranged, and substantially the entire lower surface of the ridges and the downward protrusions when the ridges are arranged in the arrangement space. It is an integral space consisting of a spare space formed between the strips, and the lower protruding strip is provided with an engaging protrusion protruding upward at the tip thereof, while the male part is the engaging portion. It is characterized by having an engaging receiving portion having a shape capable of engaging with the protrusion.

Since the floor material of the present invention has the above-mentioned structure, the joining work between the floor materials can be carried out smoothly, and the floor materials can be firmly joined without any deviation.

(A) and (b) are partially omitted schematic vertical cross-sectional views corresponding to the lines AA of FIG. 1 (a) showing the joined state of the floor material according to the other two embodiments.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the description of this embodiment defines the direction such as up and down with reference to the state in which the floor material 1 is constructed.

The floor material 1 has a male body portion 10 having a ridge 11 on one side surface in at least one direction, and a female body portion 20 having a groove space 21 having a shape capable of engaging with the ridge 11 on the other side surface. have.

The female body portion 20 is provided with an upper protruding strip 25 on the upper side of the groove space 21, and a lower protruding strip 26 protruding laterally from the upper protruding strip 25 on the lower side of the groove space 21. The groove space 21 is formed between the arrangement space 22 in which the ridges 11 are accommodated and arranged, and substantially the entire lower surface 11a of the ridges 11 and the downward protrusions 26 when the ridges 11 are arranged in the arrangement space 22. It is an integrated space including the spare space 23.

Further, the lower protruding strip 26 is provided with an engaging protrusion 27 protruding upward at its tip, while the male body portion 10 has an engaging receiver having a shape capable of engaging with the engaging protrusion 27. The part 15 is provided.

Next, the detailed configuration of the floor material 1 and the joining structure between the floor materials will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1A, the flooring material 1 is a substantially rectangular flat plate material in a plan view, and as shown in FIG. 1B, the surface material 3 is attached to the surface of the plate-shaped base material 2. It is composed with attached. The plane dimension of the floor material 1 is, for example, 303 mm × 1818 mm, and the thickness dimension is, for example, 12 mm, but of course, it is not limited to this.

Examples of the plate-shaped base material 2 include those formed of a wood-based material. Examples of the wood-based material include wood laminated boards such as plywood and LVL (single board laminated material), wood boards such as MDF (medium density fiberboard), HDF (high density fiberboard), and particle board. Further, the plate-shaped base material 2 may be made of a material other than a wood-based material such as a synthetic resin-based material.

The surface material 3 includes a single plate such as a veneer formed by processing natural wood (named wood), a decorative printing paper on which various patterns (patterns) such as a wood grain pattern are printed, and a synthetic resin such as an olefin type. Examples include system films, stone materials, and glass materials.

On both side surfaces of the plate-shaped base material 2 in the longitudinal direction and the lateral direction, a male real portion 10 is formed on one side in each direction and a female real portion 20 is formed on the other side (see FIGS. 1A and 1B). ). In the vertical cross-sectional view of FIG. 1B, both end portions in the longitudinal direction are shown. The male part 10 and the female part 20 are also formed on both side ends in the lateral direction, but since both the side ends in the longitudinal direction have the same shape, the side ends in the lateral direction are included. The vertical sectional view is omitted.

The male part 10 has a ridge 11 protruding laterally. The upper surface 11b and the lower surface 11a of the ridge 11 are substantially parallel to the back surface of the floor material 1. The male part 10 has an upper concave line 12 on the upper side of the convex line 11 and a lower concave line 13 on the lower side. The lower recess 13 is recessed deeper inward than the upper recess 12. That is, the amount of lateral protrusion of the ridge 11 on the lower surface 11a is larger than the amount of protrusion on the upper surface 11b.

A convex portion 16 protruding downward is formed on the inner side of the base portion on the lower surface 11a side of the convex strip 11, and a concave portion 17 is formed adjacent to the convex portion. The convex portion 16 and the concave portion 17 constitute an engagement receiving portion 15 having a shape in which the engaging protrusion 27 of the female real portion 20 can be engaged. It is desirable that the engaging protrusion 27 and the recess 17 of the engaging receiving portion 15 have a shape that is substantially in phase with each other as in the example of the present embodiment.

Here, it is desirable that the lower surface 11a of the ridge 11 is a flat surface substantially parallel to the back surface of the floor material 1. Further, the dimension in the thickness direction of the floor material 1 from the back surface of the floor material 1 to the lower surface 11a of the ridge 11 is the thickness direction of the floor material 1 from the back surface of the floor material 1 to the upper end of the engaging protrusion 27. It is desirable that it be larger than the size. That is, it is desirable that the height position of the lower surface 11a of the ridge 11 when the floor material 1 is installed on the floor base 5 is larger than the height position of the upper end of the engaging protrusion 27.

On the other hand, as described above, the female body portion 20 has a groove space 21 sandwiched between the upper and lower protrusions 25 by the upper protrusion 25 and the lower protrusion 26, as shown in FIG. 1 (b). In the groove space 21, the upper protrusion 25 has a smaller protrusion amount than the lower protrusion 26, the side side of the groove space 21 is open upward, and the groove space 21 leads to the upper space through the upper opening 24. ing.

The lower protruding strip 26 includes the above-mentioned engaging protrusion 27 and an extending portion 26a extending in a flat plate shape on the proximal end side of the engaging protrusion 27. The upper surface of the extending portion 26a and the lower surface of the upper protruding strip 25 are substantially parallel to the back surface of the floor material 1. The rising surface 27a on the extending portion 26a side of the engaging protrusion 27 is an ascending inclined surface, and the engaging receiving portion 15 of the male real portion 10 also becomes the rising surface 27a when the floor materials are joined to each other. An inclined receiving surface 15a is formed so as to be in close contact with each other.

The groove space 21 has an arrangement space 22 in which the ridges 11 of the floor material 1 on the opposite side are accommodated and arranged when the floor materials are joined to each other. Below the arrangement space 22, a spare space 23 that expands downward corresponding to substantially the entire lower surface of the ridge 11 when the floor materials are joined is formed. In the example of FIG. 1B, the vertical dimension of the spare space 23 is larger than the vertical dimension of the arrangement space 22, that is, the thickness of the ridge 11.

As described above, since the male part 10 and the female part 20 have the above-mentioned shapes, when the floor materials are joined to each other, the ridges 11 of the male part 10 form the arrangement space 22 of the female part 20. The upper protruding strip 25 of the female real portion 20 is arranged without a gap in the upper concave strip 12 of the male real portion 10. As a result, the convex strips 11 and the upper concave strips 12 and the arrangement space 22 and the upper protruding strips 25 are engaged so as to mesh with each other without a gap.

When the ridge 11 is accommodated in the arrangement space 22 in this way, the engaging protrusion 27 of the female real portion 20 and the engaging receiving portion 15 (recessed portion 17) of the male real portion 10 are also engaged without a gap. ing.

If the sex is joined in this way, the arrangement space 22 of the groove space 21 is filled with the ridges 11, so that the spare space 23 remains as the groove space 21. The spare space 23 is surrounded by the lower surface 11a of the ridge 11 and the wall surface 15b of the engaging receiving portion 15 continuous thereto.

As described above, in the male-female joint between the floor materials, the ridges 11 and the upper concaves 12 are engaged with the arrangement space 22 and the upper protrusions 25, and the engaging protrusions 27 and the engaging receiving portions are engaged. By engaging with the 15 at two points, the male part 10 is sandwiched between the upper protruding strip 25 and the lower protruding strip 26. In this way, sufficient joint strength can be obtained at the joint portion by male-female joint.

Further, once the floor materials are joined to each other, the engagement between the convex strip 11, the upper concave strip 12, the arrangement space 22, and the upper protruding strip 25 is the engagement, the engagement protrusion 27, and the engagement. By engaging between the receiving portions 15, the occurrence of deviation is less likely to occur, and the occurrence of gaps on the surface side can be avoided. It should be noted that, if the engagement between the engaging protrusion 27 and the engaging receiving portion 15 is configured to engage in a generally fitted state with no gap, the coupling force of the floor materials in either the vertical direction or the lateral direction is provided. Also contributes to the increase in.

Further, in the case of the present embodiment, since there is almost no gap space other than the spare space 23 at the joint portion between the male real portion 10 and the female real portion 20, deviation and the like are unlikely to occur, and a firm joint state can be obtained. .. If the ridge 11 and the female body portion 20 are joined with an adhesive, it is possible to almost certainly avoid the occurrence of deviation due to the presence of the spare space 23.

Further, since the female body portion 20 has a wide groove space 21 including a spare space 23, a tacker (tool) work is performed when the floor material 1 is installed on the floor base 5 and then fixed with nails or staples. Cheap. In particular, since the upper surface of the extending portion 26a is substantially parallel to the back surface of the floor material 1 and is flat, it is easy to drive the staples. Further, if the extension portion 26a is lengthened laterally, the staples can be driven so as to be orthogonal to the longitudinal direction of the extension portion 26a (the edge direction of the floor material 1).

Next, two examples of the joining procedure of the floor material 1 on the floor base 5 will be described with reference to FIG. In each example, the male part 10 of the newly installed floor material 1 (new floor material 1B) is actually joined to the female part 20 of the floor material 1 (existing floor material 1A) installed on the floor base 5. To do. 2 (a) and 2 (b) are views showing an example of a procedure for joining the new floor material 1B at an angle, and FIG. 2 (c) shows the new floor material 1B in the lateral direction along the floor base 5. It is a figure which shows the procedure example of more joining.

In the procedure example of FIGS. 2 (a) and 2 (b), the ridge 11 of the new floor material 1B is inserted into the groove space 21 of the existing floor material 1A from an oblique direction through the upper opening 24 (FIG. 2 (a)), and the new floor material is installed. This is a method of arranging and accommodating the ridges 11 in the arrangement space 22 while rotating the floor material 1B so as to be in a horizontal state.

When the ridge 11 of the new floor material 1B is inserted into the groove space 21, the tip of the ridge 11 of the new floor material 1B may extend to the spare space 23 because the floor material 1 is erected diagonally. .. Then, the newly installed floor material 1B is rotated, and the upper surface 11b of the convex strip 11 is brought close to the lower corner portion 25a of the upper protruding strip 25 of the female real portion 20 and slid toward the back of the groove space 21. , Convex 11 is arranged and accommodated in the arrangement space 22. In such a housing operation, the engaging protrusion 27 and the engaging receiving portion 15 are also engaged.

As described above, since the female real portion 20 has the spare space 23 below the arrangement space 22, the arrangement space 22 has a large vertical dimension leading to the upper space through the upper opening 24. And the spare space 23 are overlapped to create a space. That is, a margin in the vertical direction is created in the insertion space of the ridge 11 of the new floor material 1B. Therefore, depending on the vertical dimension of the spare space 23, the amount of protrusion of the ridge 11 of the floor material 1 can be made larger, and the inclination of the new floor material 1B can be made larger to perform the joining work.

In particular, since the spare space 23 has an area corresponding to the amount of protrusion on the lower surface 11a side of the ridge 11, a large movement region due to the rotation of the ridge 11 can be taken. Further, since the upper surface of the extending portion 26a of the lower protruding strip 26 is substantially parallel to the floor base 5 and is flat and has no unevenness, it does not interfere with the rotating convex strip 11 and is easy to operate.

Further, since this joining method is a procedure in which the upper surface 11b of the convex strip 11 is brought close to and slid the lower corner portion 25a of the upper protruding strip 25 of the female body portion 20, the lower corner portion 25a of the upper protruding strip 25 is formed on a curved surface. If you do, you can perform a smooth mounting operation.

Further, since the upper surface of the engaging protrusion 27 is higher than the lower surface of the convex portion 16 of the engaging receiving portion 15, the convex portion 16 is likely to be caught by the engaging protrusion 27 in the rotation operation, but the convex portion 16 is The engaging protrusion 27 can be easily overcome. The contact at this time creates a click feeling, and the operator can obtain a tactile feeling.

Further, since the receiving surface 15a of the engaging receiving portion 15 and the rising surface 27a of the engaging protruding portion 27 are inclined surfaces, after overcoming, they slide while being in contact with each other, and the recess of the engaging receiving portion 15 It can be engaged with the engaging protrusion 27 so as to enter the 17.

Since the engagement between the engaging receiving portion 15 and the engaging protruding portion 27 is performed by such an operation flow, when the engaging protruding portion 27 enters the recess 17 of the engaging receiving portion 15, the installation work is performed. The person can obtain a feeling like uneven fitting, and can confirm the joining of the floor materials with a tactile sensation.

As described above, according to the floor material 1, since the groove space 21 includes the spare space 23 and is a wider and larger space, it becomes easy to join males and females by rotation operation. Further, as described above, the amount of protrusion of the ridge 11 can be increased depending on the depth of the spare space 23, whereby the ridge 11 and the upper dent 12 and the groove space 21 and the upper protrusion 25 can be increased. The engagement with can be strengthened.

Further, in the floor material 1 of the present embodiment, the height position of the lower surface 11a of the ridge 11 is set to be larger than the height position of the upper end of the engaging protrusion 27. Therefore, as shown in FIG. 2C, the male part 10 can be joined to the female part 20 of the existing floor material 1A while sliding the new floor material 1B laterally onto the floor base 5. ..

Further, when the new floor material 1B is slid, the upper surface of the engaging protrusion 27 is higher than the lower surface of the convex portion 16 of the engaging receiving portion 15, so that the new floor material 1B is in the middle of the sliding operation. The convex portion 16 of the engaging receiving portion 15 collides with the engaging protruding portion 27. Therefore, the operator may lift the new floor material 1B a little at the time of a collision or before the collision, and move the convex portion 16 so as to get over the engaging protrusion 27.

Next, another form of flooring material 1 will be described. 3 (a) and 3 (b) show a floor in which the thickness of the floor material 1 and the vertical dimensions of the entire groove space 21 are substantially the same as those in FIG. 1, and the shapes and dimensions of other parts are different from those in FIG. It is a vertical sectional view of a material 1.

The floor material 1 in FIG. 3A is formed so that the thickness of the ridges 11 is thicker than that in FIG. That is, the dimensional relationship between the arrangement space 22 and the spare space 23 is different from that in FIG. 1, and the vertical dimension of the spare space 23 is smaller than the vertical dimension of the arrangement space 22.

Since the ridge 11 is thick in this way, the rotational operation of the ridge 11 in the groove space 21 is more difficult than that of the floor material 1 in FIG. However, since the ridges 11 are thicker, the strength of the ridges 11 itself and the joint strength between males and females are improved as compared with those in FIG.

Further, the floor material 1 in FIG. 3B has the same vertical dimensions as those in FIG. 1 for the ridges 11 and the groove space 21, but the lateral dimensions are different from those in FIG. Specifically, the protruding amount of the lower protruding strip 26 of the female body portion 20 is the same as that of FIG. 1, but the extending portion 26a is short, the engaging protrusion 27 is long, and the dimensional balance between the two is shown in FIG. Different from the one. That is, the position of the convex portion 16 of the engaging receiving portion 15 is closer to the inward side than that of FIG. 1, and the amount of protrusion on the lower surface side of the convex strip 11 is also smaller than that of FIG. 1, and thus the side of the groove space 21. The extension dimension toward the direction is also smaller than that in FIG.

Since the lateral extension dimension of the groove space 21 is small in this way, the rotational operation of the ridge 11 in the groove space 21 is more difficult than that of the floor material of FIG. However, since the size of the engaging protrusion 27 (recess 17 of the engaging receiving portion 15) is large, the joint strength is higher than that of FIG. Further, since the extension amount of the extension portion 26a, which is a thin wall of the lower protrusion 26, is small, the possibility that the lower protrusion 26 is damaged during handling such as carrying the floor material 1 is reduced.

As described above, the dimensions and shape of both real parts as described above affect the ease of joining work and the strength. That is, by variously adjusting the dimensions and shapes of the respective parts of both solid parts, it is possible to form the floor material 1 in which the ease of joining work and the strength are well-balanced.

Further, FIG. 4A is a vertical cross-sectional view of the floor material 1 in which the male part 10 and the female part 20 are formed of a resin material. That is, the floor material 1 has a male member 10A attached to one of both ends of a plate-shaped base material 2 having a substantially rectangular cross section, a female member 20A attached to the other, and a surface material 3 attached to their surfaces. Is. The side shape and dimensions of the male part 10 and the female part 20 are substantially the same as those in FIG.

In this way, since the male part 10 and the female part 20 are formed of the resin material, it becomes easy to process and mold the actual shape, and it is not necessary to form the actual shape on the plate-shaped base material 2 of wood. As a whole, the molding of the floor material 1 can be made more efficient. If the entire plate-shaped base material 2 including the male part 10 and the female part 20 is made of a resin material, the production efficiency of the entire floor material 1 can be improved.

Further, FIG. 4B is a vertical cross-sectional view of the floor material 1 in which the shapes of the engaging protrusion 27 and the engaging receiving portion 15 are different from those of FIG. Specifically, both the rising surface 27a of the engaging protrusion 27 and the receiving surface 15a of the engaging receiving portion 15 are surfaces perpendicular to the back surface of the floor material 1. Further, the side end surface 27b of the engaging protrusion 27 and the wall surface 15b of the engaging receiving portion 15 have an inclined shape.

As described above, since both the rising surface 27a and the receiving surface 15a are surfaces perpendicular to the back surface of the floor material 1, after the floor materials are joined to each other, the floor materials are compared with those in FIG. Is firmly meshed between the engaging protrusion 27 and the engaging receiving portion 15, and it becomes difficult to move in the direction of separation. That is, the deviation is unlikely to occur.

Further, since the side end surface 27b of the engaging protrusion 27 and the wall surface 15b of the engaging receiving portion 15 have an inclined shape, when the floor materials are joined from the lateral direction as shown in FIG. The wall surface 15b of the engaging receiving portion 15 and the side end surface 27b of the engaging protrusion 27 come into contact with each other on the inclined surfaces. Then, if the floor material 1 is further slid, the floor material 1 is smoothly lifted upward along the inclined surface, and the convex portion 16 can easily get over the engaging protrusion 27.

Further, the engaging protrusion 27 and the engaging receiving portion 15 are not limited to those having the shape shown in the present embodiment, and a recess is formed on the upper surface of the engaging protrusion 27 and is formed on the upper surface of the engaging receiving portion 15. Convex parts may be formed and they may engage. Further, the engagement between the engaging protrusion 27 and the engaging receiving portion 15 may have an engaging structure due to continuous unevenness provided on the upper surface of each.
