DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to floor panels such as floor panels for office automation and double floors for houses.

[0002]

BACKGROUND OF THE INVENTION Double beds are well known in the art. Double floors can be broadly divided into
It can be divided into two types: a column integrated type and a column separated type. A double floor with a built-in support has a problem that a step occurs between panels when there is unevenness in the floor foundation.

[0003] On the other hand, there are two types of separated support floor panels: a type in which a panel is simply provided on a support, and a type in which the support and the panel are fastened with another screw or the like. The former is
There is a problem that rattling occurs between the panels, and the latter requires a long time for fastening.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a floor panel which can be easily constructed, and which is less affected by irregularities in a floor substrate or the like and which can eliminate rattling. Is desired.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above problem by detachably connecting a top plate and a leg member supporting the top plate.

That is, an object of the present invention is to provide a detachable floor panel comprising a leg member and a top plate connected by the leg member, wherein the leg member includes a leg body and a connected top plate on the upper surface thereof. The top plate has projections corresponding to the number, and the top plate has a space portion and an engagement member that open toward the back surface of the top plate that can store the projection portion at a corner portion, and the engagement member is In order to engage the top plate and the leg member, the engaging member has an opening having a frontage that does not allow the projecting portion to pass through just by applying the projecting portion to the engaging member, and the opening is pressed against the projecting portion. By applying force to bring the top plate and the leg members closer to each other, it deforms to become a frontage through which the projection can pass, and after the projection continues to pass through the opening, the opening is substantially deformed Return to the previous state, whereby the engagement member and the protrusion When the engagement state is ensured, and when a force is applied so as to separate the top plate and the leg member from each other in the engaged state, the opening is deformed so that the floor can be detached by passing through the protrusion. It was found to be solved by the panel.

[0007] In the present invention, the engagement member is present inside the space of the top plate or at the opening of the space.
The material forming the engaging member is a material that can be deformed by applying a force, and is a material that attempts to return to an original state by removing the applied force, and is preferably a material that can be elastically deformed. "Return to the state substantially before the deformation" does not necessarily mean that the state returns to the original state completely, and it does not impair the use of the floor panel of the present invention (ie, to the extent that the effects of the present invention are achieved). ) Back is enough.

[0008] A preferred material for forming the engagement member is
Plastic material such as polyethylene resin (PE), polypropylene resin (PP), polyvinyl chloride resin (PVC), ABS resin, polycarbonate resin (PC), nylon and polyurethane, preferably sheet What is necessary is just to make from a shape-like material. Further, the force required for deformation of the engagement member can be adjusted to a desired degree by appropriately selecting the type and thickness of the material used for the engagement member.

In a first specific mode, in the floor panel according to the present invention, the leg member has a leg-shaped main body and hook-shaped projections corresponding to the number of connected top plates on the upper surface thereof. The top plate has a space portion opened toward the back surface of the top plate capable of accommodating the hook-shaped protrusion at a corner thereof, and an engaging member with a through opening, and the engaging member comprises a hook-shaped protrusion. A through-opening having an opening smaller than the cross-section of the space above the opening of the space, and having a flap-shaped portion that can be deformed, and applying the hook-shaped projection to the through-opening and pressing the protrusion toward the space. And, the frontage of the through-opening becomes substantially larger due to the deformation of the flap-shaped portion, and the hook-shaped protrusion passes through the through-opening and is housed in the space of the top plate,
When the hook-shaped protrusion accommodated in the space is to be pulled out from the space, the flap-shaped portion is deformed in the opposite direction by the hook-shaped protrusion, so that the frontage of the through-opening becomes substantially large. , The hook-shaped projections come out of the space.

The leg body may be of any shape, but preferably has no bottom surface (that is, no surface in contact with the floor substrate) and equally divides the upper surface (the surface facing the bottom surface). ,
Usually, it is defined by a cube, a rectangular parallelepiped, or a column that is easy to divide into four. In the case of a cube, the length of one side is usually about 1 to 10 cm.

In one preferred embodiment, the leg member has a hook-shaped protrusion on the upper surface of the leg member opposite to the top plate, which allows engagement with the top plate. It has an engaging member that engages with the projection and a space that houses the projection. The engagement member has a through-opening and a deformable, preferably elastically deformable, flap-like portion. In this aspect, the flap-shaped portion means a part of the engagement member whose one side is integrated with the engagement member.

[0012] It is particularly preferred that this deformation be of such a degree that it can be effected with a modest amount of force that does not require the use of special equipment in the construction of the floor panel. The through-opening of the engaging member has a frontage that does not allow the hook-shaped protrusion to pass when the flap-shaped portion is not deformed, but the frontage is further pressed by the hook-shaped protrusion contacting the flap-shaped portion. The flap-shaped portion is substantially enlarged by being deformed, so that the hook-shaped protrusion passes through the through-opening and is housed in the space of the top plate.

It is particularly preferred that when the hook-shaped projection is received in the space, the flap-shaped part recovers or attempts to recover its original shape. Normally, it is sufficient to restore the width of the through-opening after the hook-shaped protrusion is stored so that the width of the through-opening becomes slightly smaller than when the hook-shaped protrusion has passed. Thus, the deformation of the flap-like portion need not be a complete elastic deformation. Of course, it is needless to say that it is preferable to be close to complete elastic deformation.

As described above, after the hook-like portion has been received in the space, the flap-like portion returns to (or attempts to return to) its original shape, substantially closing the frontage of the opening of the engagement member. Make it smaller. Therefore, the hook-shaped member cannot pass through the opening, and the state where the hook-shaped protrusion is housed in the space of the top plate is ensured.

When the top plate is separated from the leg member, the top plate and the leg member are relatively separated from each other in the opposite directions, so that the hook-shaped protrusion contacts the flap-shaped portion. By pulling apart, the flap-like portion is deformed (in the opposite direction to the stowed case), the frontage of the opening of the engaging member becomes substantially larger, and the hook-like projection passes through the opening of the engaging member. So that the hook-shaped protrusion can pass through the opening, so that the top plate and the leg member are separated.

The flap-like portion may be provided in the engaging means in a suitable manner, for example, engaging at least one, preferably two or more notches extending from one point of the engaging member to the through opening. Just put it in the member. Alternatively, instead of the cut, an elongated hole (and thus a substantially wide cut) may be provided having a certain width and extending to the through opening.

In order to form a flap-shaped portion having such a function, the engaging member may be made of a plastic sheet as exemplified above. Further, the force required for deformation of the flap-shaped portion can be adjusted to a desired degree by appropriately selecting the type of sheet material, the thickness, the length of the cut and the like used for the engaging member. is there.

The hook-shaped protrusion protruding from the leg body has a cross-sectional shape perpendicular to the protruding direction, which partially increases in the protruding direction near the hook-shaped portion (that is, the crossover length of the protrusion is large. That is, it cannot pass through the frontage of the original through opening of the engaging member. It is particularly preferable that the hook-shaped portion forms a tapered portion tapered in the horizontal direction, so that even if the degree of deformation of the flap-shaped portion is small, the hook-shaped protrusion is stored in the space, and It becomes easy to take out.

Hook-shaped projections having the above-described functions are provided at, for example, four corners of the upper surface of, for example, a square or a rectangle of the leg member, and are provided at respective (right-angled) corners of, for example, four top plates to be connected. A space and an engaging member are provided. The arrangement of the hook-shaped protrusion, the space, and the engaging member is such that the four top plates are adjacent to each other by the leg members. That is, when the respective hook-shaped protrusions of the leg members are stored in the spaces provided at the corners of the respective top plates, the corners of the four top plates come into contact at one point. They are arranged in a line. Also, on the upper surface of the leg member, corner portions having the same area of each top plate are placed.

In a second specific embodiment of the present invention, in the floor panel of the present invention, the engaging member is attached to the bottom of the space portion, and the opening portion to which the hook-shaped protrusion is applied on the side opposite to the side to which the engaging member is attached. And a hollow columnar member having a side surface with a window. In this aspect, the cross-sectional shape perpendicular to the protruding direction of the hook-shaped protrusion is substantially larger than the cross-sectional shape of the columnar member, that is, the hook-shaped protrusion is inserted into the engagement member unless the frontage of the opening is deformed. It has a shape and dimensions that cannot be inserted.

However, in this embodiment, the engagement member is made of a deformable, preferably elastic material,
After the hook-shaped protrusion is applied to the opening, if a force is further applied to bring the top plate and the leg member closer to each other, the opening of the engaging member is deformed, and as a result, the frontage of the opening is also deformed. Thus, the hook-shaped protrusion can pass through the opening and the engagement member.

When the force is continued to be applied, the hook-like projection further enters the columnar engaging member and is inserted into the side window portion, and the hook-like portion jumps out of the window to the outside of the columnar member. At the same time as the engagement between the columnar member and the columnar member is secured, the deformed state of the opening substantially returns to the original state. in this case,
When the hook-shaped protrusion has a tapered portion in the protrusion direction,
The insertion of the engaging member into the opening is facilitated, and therefore, the opening is easily deformed. Further, if the tapered portion is also provided in a direction parallel to the protruding direction, the hook-shaped portion can easily protrude from the window to the outside and be pulled out from the window to the inside, facilitating the smooth movement between the top plate and the leg member. Reversible reversible attachment and detachment becomes possible.

In a third specific embodiment of the present invention, the engaging member has an opening at one end and an opening at the other end to which the hook-shaped projection is applied, and a slit communicating the opening. It is a deformable, preferably elastically deformable hollow columnar member, for example, a cylindrical member, and is disposed in the space at a distance from the bottom of the space. The slit is preferably provided along the same direction as the projection direction of the hook-shaped projection.

Also in this embodiment, the cross-sectional shape perpendicular to the protruding direction of the hook-shaped protrusion is substantially larger than the cross-sectional shape of the columnar member, that is, the hook-shaped protrusion is engaged unless the frontage of the opening is deformed. It has a shape and dimensions that cannot be inserted into the joining member. However, in this embodiment, the engagement member is made of a deformable, preferably elastic material, so that after the hook-shaped projection is applied to the opening, the top plate and the leg member are further brought close to each other. When the force is applied, the width of the slit is increased, so that the engaging member is deformed. As a result, the shape of the opening is also deformed, the frontage is widened, and the hook-shaped protrusion can pass through the opening and the engaging member. become.

When the force is continuously applied, the hook-like projection passes through the inside of the columnar engaging member and jumps out of the other opening, and the root portion (the portion other than the hook-like portion) of the hook-like member is Located within. At that time, the columnar member returns from the deformed state to the original state, and the root portion is held in the columnar member, and the engagement between the hook-like member and the columnar member is ensured.

In this case, the hook-shaped member may have a hook-shaped portion bent in at least one direction perpendicular to the protruding direction, but preferably has the hook-shaped portion radially. That is,
The hook-shaped protrusion is a columnar member having a cross-sectional shape of an end portion that is substantially larger than a portion other than the end portion. Accordingly, for example, cylinders having different diameters overlap each other.

In this embodiment, when the hook-shaped protrusion has a tapered portion in the protruding direction and in a direction opposite to the protruding direction, the columnar member is easily deformed, and smooth reversible attachment and detachment between the top plate and the leg member is possible. It becomes possible. Also in the second and third specific modes described above, unless there is a particular contradiction, the first mode may be used.
The description of the embodiment is applicable. For example, the engaging member can be made from the same material as in the first embodiment, and the description in the first embodiment applies to the leg body.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. "FIG. 1" to "FIG. 7" show the first specific mode, "FIG. 8" to "FIG. 11" show the second specific mode, and "FIG. 12" to "FIG. 15" Indicates a third specific mode.

FIG. 1 schematically shows a perspective view of a leg member 1 used for the floor panel of the present invention. FIG. 2 schematically shows a side view from the direction of the arrow in FIG. The leg member 1 includes a leg body 3 and at least two (four in the illustrated embodiment) protrusions 5 protruding therefrom.

In the embodiment shown in FIG. 1, the leg body 3
Has substantially no bottom surface (that is, the surface in contact with the floor substrate is only the thickness of the side surface), and the upper surface 7 (the surface facing the bottom surface) is equally divided, usually, into four equal parts. For the sake of simplicity, the upper surface 7 is defined by a rectangular parallelepiped having a substantially square shape. In the case of the illustrated embodiment, the length of one side of the upper surface of the rectangular parallelepiped is usually about 1 to 15 cm, and the height is usually 2 to
It is about 20 cm.

The upper surface 7 of the leg body 3 is flat, and has a projection 5 at or near a corner (as shown). The protruding portion 5 protrudes vertically with respect to the upper surface 7, and a tip portion 9 thereof is bent in a horizontal direction to define a hook-like portion, and the protruding portion 5 forms a hook-like protruding portion 11 as a whole. . The horizontal portion (hook-like portion) of the hook-like protrusion 11 is
As shown in the figure, it is particularly preferable that a tapered portion is formed toward the tip, that is, a surface that is not parallel to the upper surface 7 is defined.

In the illustrated embodiment, the taper is
Tapering toward the center of the square, which is the top
It tapers to the corners of two adjacent squares). In another aspect, the taper may taper to only one of the adjacent corners. In addition, the direction of such a tapered portion may be in a state of being rotated at any angle around the axial direction of the protrusion, that is, the direction of the hook-shaped portion may be in any direction. Well, for example, "Figure 1"
May be a direction appropriately rotated around an axis indicated by a dashed line at the hook-shaped protrusion at the forefront of the above. However, it is necessary to make the through-opening of the engaging member correspond to it.

FIG. 3 schematically shows one corner portion of the back surface of the top plate 21 (that is, the surface facing the floor base when a floor is formed) applicable to the leg member of FIG. Show. Top plate 2
1 may be made of any suitable material that can be used for floor panels, for example metal plates, plywood, synthetic resin or concrete floor panels. The top plate 21 has a space portion 23 at or near the corner of the back surface for accommodating the hook-like portion of the leg member. The space is large enough to allow the hook-shaped protrusion to move slightly within the space.

The top plate 21 further has an engaging member 25. The engaging member 25 is formed of a deformable, particularly elastically deformable sheet material, and is attached to the back surface of the top plate 21 by an appropriate method (for example, an adhesive, nailing, or the like) to form a space. The opening of the portion 23 is covered. The engaging member 25 has a through opening 27 smaller than the opening of the space 23.
And a flap-shaped portion 31 is formed by making a cut 29 toward the through opening.

In the embodiment shown in FIG. 3, the through opening 27
Is not on a line that bisects the angle of the corner of the tabletop, so the top surface of the leg body suitable for such a tabletop is not a square as shown in FIG. 1 but a rectangle.

The through-opening 27 of the engaging member 25 has a frontage (the length L ₁ in FIG. 6) of the hook-like projection smaller than the hooking length (L _{2 in} FIG. 5). When the flap-shaped portion 31 is not deformed due to the difference in length, the hook-shaped protrusion 11 cannot pass through the through-opening 27. The width of the hook portion may be smaller, larger, or substantially the same as the length of the corresponding through-opening.

When the width is small, the shape portion can be easily applied to the through opening. If the widths are large or the same, an additional flap-shaped portion needs to be provided so that the widthwise width of the through-opening 27 becomes large in order for the hook-shaped protrusion 11 to pass through the through-opening 27. is there.

As described above, if the engaging member 25 does not have the cutout portion 29, the hook-shaped protrusion 11 cannot pass through the through opening 27 and enter the space 23 of the top plate 21. However, in the present invention, the engagement member 25
Has a flap-shaped portion 31 that can be deformed, so that the hook-shaped protrusion 11 is pressed toward the space 23 after being applied to the through-opening 27 (arrow A in FIG. 4).
And / or when a force is applied in the direction of B), the hook-shaped projection 11 pushes and bends the flap-shaped part 31, whereby the frontage of the through-opening 27 increases and the hook-shaped projection 1
1 can pass through the opening 27 and enter the space 23. FIG. 4 schematically shows a state in which the flap-shaped portion 31 is deformed, and FIG. 5 shows a state in which the hook-shaped protrusion 11 is housed in the space 23.

As can be understood from FIG. 5, once the hook-shaped projection 11 is stored in the space 23, the flap-shaped portion 31 recovers its original shape and functions as a stopper, The protrusion 11 is prevented from easily coming out of the space 23, and the fitting relationship between the top plate 21 and the leg member 1 is ensured.

However, when a force of a certain degree or more is applied in the directions of arrows C and / or D, the lower portion of the hook-shaped protrusion 11 comes into contact with the flap-shaped portion 31, and this is applied (see FIG. 4). In the opposite direction), so that the frontage of the through-opening 27 becomes substantially larger, so that the hook-shaped protrusion 11 can be pulled out of the space 23.

One leg member supports a connecting portion of a plurality of, usually four, top plates (therefore, a corner portion of the four top plates). 4
FIG. 6 schematically shows a state in which the top plates 21 are connected (leg members are not yet engaged) as viewed from the back side. For clarity, the through opening 27 of the engaging member 25 is hatched. In the illustrated embodiment, the frontage of the through-opening 27 (the length L ₁ in FIG. 6) is smaller than the length of the hook-shaped portion (the length L ₂ in FIG. 5). The space 23 indicated by the broken line is large enough to accommodate the hook-like portion.

The hooked projections 11 of one leg member 1 are engaged with the four through-opening portions 27 shown in the drawing, whereby the four top plates 21 are connected. This state is schematically shown in FIG. Also in this case, the back surface of the floor panel (as viewed from the floor base) is shown as in FIG. For the sake of clarity, the portion occupied by the hook-shaped protrusion 11 is indicated by oblique lines. For example, a cylinder for fitting a cushioning member made of rubber as an auxiliary leg, preferably a hollow cylindrical portion 35, is indicated by a double circle at the center. The auxiliary leg is usually fitted so as to be slightly exposed from the bottom surface of the leg member fixing the top plate.

As is apparent from FIG. 7, the corners of the four top plates are placed on the upper surface of the leg member with the same area. That is, the protrusion is provided so that the area of the top plate placed on the upper surface of one leg member is equal. Therefore, for example, when the leg member main body is a cube or a rectangular parallelepiped, four projections are provided on the diagonal line of the upper surface and at the same distance from the intersection of the diagonal lines. In the case of a columnar shape, four protrusions are provided at equal positions from the center of the circle every 90 °.

FIGS. 8 to 11 schematically show a second specific embodiment of the present invention. In FIG.
9 shows a state viewed from below (the floor base side), and the leg member 1 shows a state viewed from above. In FIGS. 9 to 11, the top plate 21 is a cross-sectional view of the leg member 1. Is shown in a side view.
The engaging member 25 has a hollow rectangular column shape, and is attached to the bottom 41 of the space by an appropriate method, for example, an adhesive.
It has an opening 27. As shown in FIG. 9, the hook-shaped protrusion 11 is applied to this opening in the direction of arrow E, but the hook-shaped protrusion 11 cannot pass through the opening 27 by merely applying the hook-shaped protrusion 11. . In addition, the engagement member 25
It has a window portion 43 on its side.

When a force is further applied in the direction of arrow E after the hook-shaped protrusion 11 is applied to the opening 27, the engaging member 25 is deformed as shown in FIG.
The frontage is substantially widened so that the hook-shaped protrusion can pass through, and further, when a force is applied, the hook-shaped portion 45 pops out of the window portion 43, whereby the engaging member 25 is shown in FIG. It is possible to return to the original state. Thereby, the engagement between the top plate 21 and the leg member 1 is ensured.

As can be seen from the figure, the hook-shaped protrusion 11
It has a tapered portion formed by the two sides 47 and 48 in the protruding direction. As a result, the hook-like projection is
7 can be easily applied. The hook-shaped protrusion 11
Further, it also has a tapered portion formed by the two sides 48 and 49 in the horizontal direction. Thereby, the hook-like portion 45
From the window portion 43 can be easily pulled out and pulled out. In the illustrated embodiment, the window portion is located only on one side, but the window portion may be present on a plurality of side surfaces.

FIGS. 12 to 15 schematically show a third specific embodiment of the present invention. In FIG. 12, the top plate 21 is viewed from below (the side of the floor substrate). FIG. 13 to FIG. 15 show the top plate 21 in a cross-sectional view and the leg member 1 in a side view.

The engaging member 25 has a hollow cylindrical shape and has an opening 27 at one end to which the hook-shaped protrusion 11 is applied, and an opening 51 at the other end. The openings are connected by slits 53. Engaging member 25
Is mounted by an appropriate method at a distance from the bottom 41 of the space 23. For example, as shown in FIG. 12, an appropriate member 55 may be provided on the engaging member 25 on the side facing the slit, and the member may be attached to the wall 57 constituting the space by, for example, bonding. In this case, it should be particularly noted that the engaging member should not be mounted such that the deformation of the engaging member is prevented and the frontage of the opening does not widen.

The hook-shaped protrusion 11 may be bent in only one direction perpendicular to the protruding direction as in the first and second specific embodiments. (Specifically, in six directions) to form a hexagonal prism having a hook-shaped portion, and the cross-sectional shape of the end portion 59 is changed to the other portion 61
It is getting bigger. Instead of a hexagonal prism, it may be cylindrical. As shown in FIG. 13, the hook-shaped protrusion 11 is applied to the opening 27 as shown by the arrow F. However, the hook-shaped protrusion cannot pass through the opening 27 by merely applying the hook-shaped protrusion 11. .

When a force is further applied in the direction of arrow F after the hook-shaped protrusion 11 has been applied, the width of the slit 53 is widened as shown in FIG. The portion 27 is substantially widened so that the hook-shaped protrusion can pass therethrough, and further, when a force is applied, the hook-shaped portion 59 jumps out of the other opening 51 so that the engaging member 25 is moved to the position shown in FIG. It is possible to return to the original state as shown in FIG. Thereby, the engagement between the top plate 21 and the leg member 1 is ensured.

As can be seen from the figure, the hook-shaped protrusion 11
It has a tapered portion 63 in the protruding direction. Thus, the hook-shaped protrusion can be easily applied to the opening 27, and the slit 53 can be smoothly deformed when the top plate 21 and the leg member 1 are connected or separated.

In each of the illustrated embodiments, the hook-shaped legs are present at the corners on the upper surface of the leg member, but the hook-shaped portions need not necessarily be located at the corners.

When the floor panel of the present invention is installed on a floor substrate, the leg members are arranged on the floor substrate at predetermined intervals, or are arranged while adjusting the interval, and a top plate is placed thereon to face the floor substrate. Just press the top plate. Conversely, when removing the top panel from the floor panel, the top panel can be separated from the leg members simply by lifting the top panel. Also,
The surface of the top plate may be provided with a floor finishing material such as a tile carpet or a wood veneer.

[0054]

Since each corner of a plurality of top plates is placed and fixed on the upper surface of one leg member, these top plates are always present on one plane, and the excellent surface smoothness of the floor panel is achieved. Property is obtained. Further, since the leg member and the top plate are detachably engaged and fixed, the construction of the floor panel is facilitated.

[0055]

EXAMPLE A leg member made of polycarbonate and having a square shape with a side of 70 mm on the upper surface was manufactured. At the four corners of the upper surface of the leg member, protrusions having a height of 10 mm are provided, and the tip portion is bent in the horizontal direction, and a hook-like protrusion is provided as a shape having a tapered portion tapering toward the center of the square. , And a leg member as shown in FIG. 1 (L ₂ is 1
3 mm).

The top plate has a side of 500 mm and a height of 15 mm.
(The length of one side of the back side is 495 mm, and the top plates are in line contact with each other on the front side as shown in FIG. 4). On the back side of the top plate, a space having a 15 mm side and a 15 mm side opening was provided. In addition, a 1 mm-thick polyester sheet was used as the engagement member,
A through opening of 10 mm × 10 mm is provided (L ₁ = 10 m
m), 10 mm cuts were made from the corners of the openings at two places as shown in FIG. 3 to form flap-shaped portions. Further, a wood veneer was laminated on the front surface of the top plate.

The manufactured leg members are laid on the floor base so as to correspond to the space portions of the top plate, the top plate is placed thereon, pressed lightly, and housed in the hook-shaped protrusions and the space portion. The work of fitting the plate and the leg members was repeated to complete the connected floor panel. In this floor panel, there is a certain amount of room in the space (more than the flap-shaped part is elastically deformed and the hook-shaped protrusion is housed in the space). There was no rattling because the space could absorb the irregularities. Further, even when the wiring layout was changed, the top plate could be easily removed from only necessary portions.

[0058]

As described above, a plurality of floor panel top plates are placed on one plane of the leg member, and a plurality of connected top plates form the same plane. It is easy to attach and detach, easy to construct, and can remove only the top plate at the required location. Even if there is unevenness in the floor substrate, it can be absorbed and a smooth floor surface can be obtained by placing the finishing material on the top plate.

The top plate has a space portion and an engaging member that open toward the back surface of the top plate that can accommodate the protruding portion at a corner thereof, and the engaging member includes a top plate and a leg. In order to engage the member, the engaging member has an opening having a frontage that does not allow the protrusion to pass through when the protrusion is merely applied to the engaging member, and the opening is formed by applying a force so that the protrusion is pressed against the protrusion. By bringing the plate and the leg member closer to each other, it deforms to become a frontage through which the projection can pass, and after the projection continues to pass through the opening after applying force, the opening substantially returns to the state before deformation As a result, the engagement state of the engagement member and the projection is ensured. Further, when a force is applied to separate the top plate and the leg member from each other in the engaged state, the opening is deformed, and the floor panel is configured to be detachable by passing through the protrusion, The protrusion is a hook-shaped protrusion, and the top plate has an engaging member with a through-opening. The engaging member has a through-opening having an opening smaller than the cross section of the hook-shaped protrusion. A floor panel having an opening and having a flap-like portion that can be deformed.
