Description

  The present invention relates to a flooring and a connecting member laid on a balcony, a veranda, a terrace, and the like, and more particularly to a flooring and a connecting member used for the connection.

  This type of flooring has a panel-like flooring body. Female fitting portions are provided on the two edges of the flooring main body, and male fitting portions are provided on the other two edges. A plurality of flooring materials are arranged vertically and horizontally. When the other male fitting portion is fitted to one female fitting portion in the adjacent floor material, these floor materials are connected. In some cases, the edges of adjacent floor members on the male fitting portion side are connected via a connecting member (see, for example, Patent Document 1). The connecting member has at least a pair of female fitting portions, and a male fitting portion of a corresponding floor material is fitted to each female fitting portion.

JP 2006-28752 A

  The male fitting part of patent document 1 etc. becomes the cylinder shape by which the lower end (tip) was opened. Therefore, it is easily deformed so that the lower end of the male fitting portion is narrowed. Further, in general, a portion including a male fitting portion in this type of flooring is formed by a molding die, and therefore, the male fitting portion has a drop gradient for demolding (a taper slightly tapered toward the tip side). ) Is often attached. For this reason, the fitting between the male fitting portion and the female fitting portion was easy to come off.

In order to solve the above problems, the present invention is a floor material (first floor material) that should constitute a floor material laying body,
A panel-like flooring body, and a first male fitting part protruding from the bottom of the flooring body, wherein the first male fitting part is the second flooring of the flooring material or the It can be press-fitted into the second fitting hole of the second female fitting portion formed in the connecting member interposed between the second floor material,
In the first male fitting portion, a portion on the distal end side in the projecting direction (axial direction) from the normal pressure contacting portion with the inner peripheral surface of the second fitting hole is set to a portion on the distal end side. It is characterized in that a deformation resistance portion is provided which makes it more difficult to be elastically deformed.

  A plurality of floor materials can be arranged side by side, and the other second female fitting portion can be fitted and connected to one first male fitting portion of two adjacent floor materials. In this connected state, when the first male fitting portion tries to come out of the second female fitting portion, deformation resistance due to deformation resistance acts. Thereby, it can prevent that a 1st male fitting part remove | deviates from a 2nd female fitting part. Even if the first male fitting portion has a removal gradient for demolding, the first male fitting portion can be reliably prevented from being detached from the second female fitting portion. Here, the regular pressure contact portion refers to a portion where the first male fitting portion is in pressure contact with the inner peripheral surface of the second fitting hole when the floor members are in a prescribed connected state.

  The cross-sectional area perpendicular to the protruding direction (axial direction) of the first male fitting portion in the tip side portion is larger than the cross-sectional area perpendicular to the protruding direction of the first male fitting portion in the regular pressure contact portion. Larger is preferred. This makes it possible to ensure that the tip side portion is less likely to be elastically deformed more reliably than a regular pressure contact portion.

The first male fitting portion is cylindrical;
It is preferable that the deformation resistance portion has a bottom plate shape, an inner flange shape, or a bar shape and is provided inside the portion on the distal end side of the first male fitting portion. Thereby, the portion on the distal end side can be reliably prevented from being elastically deformed, and the first male fitting portion can be reliably prevented from coming off from the second female fitting portion. There is no need to project the deformation resistance portion radially outward of the first male fitting portion, and molding can be facilitated.

The first male fitting portion is provided at one edge of the floor material body,
A first female fitting portion having a first fitting hole into which a third male fitting portion in a third floor material of the floor material laying body is fitted is provided at the other edge portion of the floor material main body;
Preferably, a first protrusion is formed on the inner peripheral surface of the first fitting hole so as to project toward the inside of the first fitting hole and press-contact with the third male fitting portion. .
Thereby, a plurality of flooring materials can be arranged side by side, and the other third male fitting portion can be fitted and connected to one first female fitting portion of two adjacent flooring materials. By tapering the first protrusion, the pressure contact with the third male fitting portion can be increased. Therefore, the fitting portions can be made more difficult to come off.

A second protrusion is formed on the inner peripheral surface of the second fitting hole in the connecting member so as to project toward the inside of the second fitting hole and press-contact with the first male fitting. It is preferable.
Thereby, a plurality of flooring materials can be arranged side by side, and two adjacent flooring materials can be connected to each other via the connecting member. By tapering the second protrusion of the connecting member, the pressure contact with the first male fitting portion can be increased. Therefore, the fitting portions can be made more difficult to come off.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
1 to 7 show a first embodiment of the present invention. As shown in FIG. 4, for example, a floor material laying body 1 is installed on a floor surface F such as a balcony, a veranda, and a terrace of a building (not shown) such as a house. The floor material laying body 1 is composed of a plurality of floor materials 2 (only three are shown in FIG. 4). These flooring materials 2 are arranged vertically and horizontally in a grid pattern. Adjacent flooring materials 2 are connected to each other.

  As shown in FIG. 1, each flooring 2 includes a panel-like flooring main body 10 and fitting portions 30 and 40. As shown in FIG. 2, the flooring main body 10 includes a floor panel 11 and a frame 20. As shown in FIGS. 1A and 2A, the floor panel 11 is divided into, for example, four single panels 12. Each single panel 12 has a rectangular flat plate shape in plan view. Four single panels 12 are aligned vertically and horizontally. The material of the single panel 12 is a tile, but may be a resin.

  As shown in FIG. 2A, a frame 20 is provided on the lower side of the floor panel 11. As shown in FIG. 2B and FIG. 3, the frame 20 integrally includes a vertical and horizontal lattice frame portion 21 and an X-shaped interlaced portion 23 provided in each lattice hole 22. Legs 24 are provided at the intersections of the lattice frame portion 21 and the two muscle intersection portions 23. The material of the frame 20 is, for example, resin.

  The single panel 12 and the frame 20 are joined to each other by adhesion. The joining means is not limited to adhesion, but may be screwing, fusion, or the like. The single panel 12 and the frame 20 may be integrally formed of resin.

  As shown in FIG. 1B, fitting portions 30 and 40 are integrally formed on the frame 20 of the flooring 2. A plurality of male fitting portions 30 are provided at intervals between two orthogonal edges of the flooring 2. A plurality of female fitting portions 40 are provided at intervals on the other two edges of the flooring 2.

  Furthermore, a plurality of male fitting portions 30G are also provided in a thick central lattice frame portion 21C that divides the frame 20 into four parts vertically and horizontally. The center male fitting portion 30G is disposed with a gap between both edges of the center lattice frame portion 21C. The center male fitting portion 30G is used as a connecting means when the flooring 2 is cut into a half size or a quarter size by cutting along the center line of the center lattice frame portion 21C ( (See FIG. 13).

  As shown in FIG. 3, each male fitting portion 30 protrudes downward from the frame 20 and thus the bottom portion of the flooring main body 10. The male fitting portion 30 has a cylindrical shape whose outer periphery is a square or an oval. The internal space of the male fitting part 30 is opened to the upper surface of the frame 20. As shown in FIG. 5A, a bottom plate portion 34 (bottom plate-shaped deformation resistance portion) is provided at the lower end portion (portion on the front end side in the protruding direction) of the male fitting portion 30. The bottom plate portion 34 protrudes inward from the inner peripheral surface of the intermediate portion of the male fitting portion 30 and closes the lower end portion of the male fitting portion 30. The horizontal cross-sectional area at the bottom plate portion 34 (cross-sectional area perpendicular to the protruding direction of the male fitting portion 30) is larger than the horizontal cross-sectional area at the intermediate portion of the male fitting portion 30. As a result, as shown in FIG. 6B, the lower end portion of the male fitting portion 30 is less likely to be elastically deformed than the intermediate portion and thus the later-described normal pressure contact portion 31 a.

As shown in FIGS. 1 and 2, each female fitting portion 40 extends horizontally outward from the edge of the flooring main body 10. The female fitting part 40 has a circular fitting hole 41 and has an annular shape. As shown in FIGS. 5A and 6A, the inner diameter of the fitting hole 41 is larger than the outer diameter or the width W ₃₀ of the male fitting portion 30. A pair of protrusions 44 are formed on the inner peripheral surface of the fitting hole 41. These protrusions 44 are opposed to each other in the extending direction (left and right in FIG. 6) of the edge where the female fitting portion 40 is provided in the flooring main body 10. Each projecting portion 44 projects in a tapered manner toward the inside of the fitting hole 41 and thus toward the mating projecting portion 44. The protruding end surface 44e of the protruding portion 44 extends straight along the horizontal extending direction (the left-right direction in FIG. 5A) of the female fitting portion 40 from the floor material body 10. As shown in FIG. 6A, the distance D ₄₄ between the protruding end surfaces 44 e of the pair of protrusions 44 in the non-fitted state between the fitting parts 30 and 40 is the width W _{30 of the} male fitting part _30. Slightly smaller (D ₄₄ <W ₃₀ ). Therefore, the male fitting part 30 can be press-fitted into the fitting hole 41 of the female fitting part 40 of another floor material 2.

  As shown in FIGS. 4 and 5 (b), in the floor laying body 1, the male fitting portion 30 of one floor material 2 is adjacent to the female fitting of the other floor material 2. The floor materials 2 are connected to each other by being fitted into the joint portion 40. These flooring materials 2 are placed on the floor surface F, and the leg portions 24 of these flooring materials 2 are in contact with the floor surface F so that they are in a stable state. The connection state between the fitting portions 30 and 40 in this stable state is referred to as a “prescribed connection state”. In the present embodiment, the lower surface of the male fitting portion 30 (the lower surface of the bottom plate portion 34) and the lower surface of the female fitting portion 40 are flush with each other and are in contact with the floor surface F in the prescribed connected state. Yes.

  For example, the lower left flooring 2 in FIG. 4 is the first flooring 2A, the right flooring 2 is the second flooring 2B in FIG. 4, and the upper flooring 2 in FIG. 4 is the third flooring. When the material 2C is used, the male fitting portion 30 on the second floor material 2B side (right side) in the first floor material 2A constitutes the first male fitting portion 30A, and the first floor material 2A side in the second floor material 2B. The (left side) female fitting portion 40 constitutes the second female fitting portion 40B. The female fitting portion 40 on the third floor material 2C side (upper side in FIG. 4) in the first floor material 2A constitutes the first female fitting portion 40A, and the first floor material 2A side in the third floor material 2C (see FIG. The lower male fitting portion 30 in FIG. 4 constitutes the third male fitting portion 30C. Furthermore, the fitting hole 41 of the first female fitting portion 40A constitutes a first fitting hole 41A, and the projection 44 of the first fitting hole 41 constitutes a first projection 44A. The fitting hole 41 of the second female fitting portion 40B constitutes the second fitting hole 41B.

  As shown in FIG. 5 (b), between the inner peripheral surface of the female fitting part 40 and the male fitting part 30, the horizontal extending direction of the female fitting part 40 (the left-right direction in FIG. 5 (b)). ) Is provided with a margin (gap). The relative position can be adjusted so that adjacent flooring materials 2 approach and separate from each other in the facing direction (left and right in FIG. 5B) by this margin.

  As shown in FIG. 6B, in the prescribed connection state, the pair of protrusions 44 are in pressure contact with the intermediate portion (regular pressure contact portion 31a) of the male fitting portion 30, respectively. For this reason, the adjacent flooring materials 2 are connected so as not to be relatively displaceable in a horizontal direction (left and right in FIG. 6B) orthogonal to the opposing direction. The regular pressure contact part 31 a is located above the bottom plate part 34. At least one of the regular pressure contact portion 31a and the protrusion 44 is slightly elastically deformed by the pressure contact.

  When constructing the floor material laying body 1 described above, a plurality of floor materials 2 are arranged vertically and horizontally on the floor surface F, and one male fitting portion 30 of the two adjacent floor materials 2 is placed on the other side. Press fit into the female fitting portion 40 and fit. Thereby, the adjacent flooring materials 2 can be connected. The protrusions 44 are brought into pressure contact with the pressure contact portion 31a, so that the fitting portions 30 and 40 are unlikely to come off. Furthermore, the contact pressure can be increased by tapering the protrusion 44, and the fitting portions 30 and 40 can be further prevented from coming off.

  As shown by a solid line in FIG. 7, in order for the male fitting portion 30 to come out of the female fitting portion 40, it is necessary that the protruding portion 44 relatively move to the bottom plate portion 34 side. On the other hand, the bottom plate portion 34 has higher rigidity and is less likely to be deformed than the regular pressure contact portion 31a. For this reason, when the projection part 44 tries to shift to the bottom plate part 34 side, a strong deformation resistance works and the transition is prevented. That is, the protrusion 44 is prevented from riding on the outer surface of the bottom plate portion 34 (the state indicated by the two-dot chain line in FIG. 7). Thereby, it is possible to reliably prevent the male fitting portion 30 from coming off the female fitting portion 40. Even if the male fitting portion 30 has a slight taper-like inclination (not shown in detail) for demolding, the male fitting portion 30 can be reliably prevented from being detached from the female fitting portion 40. As a result, it can prevent reliably that the adjacent flooring 2 is decoupled.

Next, another embodiment of the present invention will be described. In the following embodiments, the same reference numerals are given to the drawings for the same configurations as those already described, and the description thereof is omitted.
FIG. 8 relates to a deformation mode of the deformation resistance portion. A hole 34 c is formed at the center of the bottom plate portion 34 </ b> B of the male fitting portion 30. Accordingly, the bottom plate portion 34B has an annular inner flange shape. In other words, the lower end portion (tip portion) of the male fitting portion 30 is formed with an inner flange-shaped deformation resistance portion 34B that protrudes radially inward. The lower end portion of the male fitting portion 30 is partially blocked by the inner flange 34B. In short, the deformation resistance portion only needs to at least partially block the lower end portion of the male fitting portion 30.
The point that the regular pressure contact portion 31a with the projection 44 is positioned above the inner flange 34B is the same as in the first embodiment (FIG. 6B). Since the lower end portion of the male fitting portion 30 has the inner flange 34B, it is less likely to be elastically deformed than the press contact portion 31a.
When the male fitting part 30 tries to come out of the female fitting part 40, the inner flange 34B (deformation resistance part) resists, thereby preventing the male fitting part 30 from coming off the female fitting part 40. it can.

  FIG. 9 relates to another modification of the deformation resistance unit. The bottom plate portion 34 (deformation resistance portion) of this aspect is disposed slightly above the lowermost end surface of the male fitting portion 30. An annular convex edge portion 35 is formed at the lower end portion of the male fitting portion 30. The convex edge portion 35 protrudes downward from the bottom plate portion 34. The point that the press-contact part 31a with the projection part 44 is located above the bottom plate part 34 is the same as in the first embodiment (FIG. 6B).

  FIG. 10 is a combination of the two modified modes (FIGS. 8 and 9). In this aspect, the bottom plate portion with the hole 34 c, that is, the inner flange 34 </ b> B is disposed slightly above the lowermost end surface of the male fitting portion 30.

  FIG. 11 relates to another modification of the deformation resistance unit. The male fitting portion 30 of this aspect includes a peripheral wall 31 and a crosspiece 36 (a cross-shaped deformation resistance portion). The peripheral wall 31 is formed in a cylindrical shape, and both upper and lower ends are opened. A crosspiece 36 is provided inside the lower end portion (tip portion in the protruding direction) of the peripheral wall 31. The crosspiece 36 extends linearly along one radial direction of the peripheral wall 31. Both end portions of the crosspiece 36 are integrally connected to the peripheral wall 31. Thereby, the compressive strength along the extending direction of the crosspiece 36 can be applied to the lower end portion of the male fitting portion 30. As shown in FIG. 11 (d), the extending direction of the crosspiece 36 (left and right in the figure) is coincident with the opposing direction of the pair of protrusions 44 of the female fitting portion 40. The lower end surface of the crosspiece 36 is flush with the lower end surface of the peripheral wall 31.

As shown in FIG. 11 (d), the protrusion 44 is in pressure contact with the outer peripheral surface of the peripheral wall 31 above the crosspiece 36 in the prescribed connection state between the fitting portions 30 and 40. That is, the regular pressure contact part 31a is located above the crosspiece 36 (deformation resistance part).
According to the embodiment of FIG. 11, when the male fitting portion 30 tries to come out of the female fitting portion 40, compression resistance acts in the extending direction of the crosspiece 36. Thereby, it is possible to prevent the male fitting portion 30 from being detached from the female fitting portion 40.
In short, the deformation resistance due to the deformation resistance portion only needs to work in at least the direction in which the pressure contact force of the female fitting portion 40 acts (the direction in which the protrusions 44 face each other). It is not necessary for the deformation resistance to work uniformly in all directions around it.

  FIG. 12 relates to a modification of the embodiment of FIG. In this aspect, the lower end surface of the crosspiece 36 is positioned above the lower end surface of the peripheral wall 31. In other words, the peripheral wall 31 protrudes below the crosspiece 36. A convex edge portion 35 is formed at the lower end portion of the male fitting portion 30. As shown in FIG. 12 (d), the point that the pressure contact portion 31a with the projection 44 is positioned above the crosspiece 36 in the prescribed connection state between the fitting portions 30 and 40 is the mode shown in FIG. It is the same.

Second Embodiment
13 to 15 show a second embodiment of the present invention. As shown to Fig.13 (a), the flooring construction body 1E of 2nd Embodiment is equipped with the flooring materials 2 and 2E and the connection member 50. As shown in FIG. The flooring 2E is made into a half size by cutting the flooring 2 of FIG. 2 along the center line of the central lattice frame portion 21C in the vertical direction. The floor materials 2E are arranged adjacent to each other so that the cut surface of the floor material 2E faces the floor material 2. A male fitting portion 30G is disposed on the bottom surface of the edge on the floor material 2 side in the floor material 2E.

  A connecting member 50 is interposed between the floor materials 2 and 2E. The connecting member 50 has a pair of second female fitting portions 51. The second female fitting portion 51 has the same structure as the female fitting portion 40 of the flooring 2. In other words, the second female fitting portion 51 has an annular shape having the second fitting hole 51a, and a pair of second protrusions 54 are formed on the inner peripheral surface of the fitting hole 51a. Each of the second protrusions 54 protrudes in a tapered manner toward the other second protrusion 54.

  The material of the connecting member 50 is not particularly limited, and is made of, for example, resin. Preferably, the connecting member 50 is made of a resin having a higher elastic modulus than that of the frame 20. The connecting member 50 may be made of a material that is less elastically deformed than the frame 20, or may be made of the same material as the frame 20.

  As shown in FIGS. 13B and 14, the connecting member 50 in the floor covering 1 </ b> E straddles the lower surfaces of the floor coverings 2 and 2 </ b> E. The male fitting portion 30 of the flooring 2 is fitted into the fitting hole 51a of the female fitting portion 51 on the one side (left side in FIG. 14). The male fitting portion 30G of the flooring 2E is fitted into the fitting hole 51a of the female fitting portion 51 on the other side (right side in FIG. 14). As shown in FIG. 15, the protrusion 54 of each female fitting portion 51 is pressed against the male fitting portions 30 and 30G. Accordingly, the floor materials 2 and 2E are connected to each other via the connecting member 50.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the deformation resistance portion may have a spoke shape including a plurality of crosspieces 36 having different directions. The protrusions 44 of the fitting hole 41 are not limited to a pair, and at least one protrusion is sufficient.
In 2nd Embodiment (FIGS. 13-15), the deformation | transformation resistance part of the male fitting part 30 may become the structure similar to deformation | transformation aspects, such as FIGS.
The floor material 2A has only the first male fitting portion 30A among the male and female fitting portions, the female fitting portion may not have, and the second floor material 2B has the male and female fitting portions. It has only the 2nd female fitting part 40B, and does not need to have a male fitting part.

  The present invention can be applied to floor materials laid on floors such as balconies, verandas, and terraces.
