Description

Floor system and floor buckle

Technical Field

The application relates to the field of floors, in particular to a floor system and a floor buckle.

Background

Chinese patent No. CN200880124150.6 discloses a floor buckle structure for floor, especially for the side of floor. The corresponding written parts of the specification of this patent document and the male and female snaps disclosed in the accompanying figures 2a and 2b of the specification are locked and engaged with each other in a relative rotational manner and disengaged from each other in a counter rotational manner. However, the male and female snaps of this structure suffer from the following drawbacks:

1. after the assembly is completed, the male buckle and the female buckle are provided with four pairs of matching surfaces (see 31-32 matching surfaces, 33-34 matching surfaces, 35-36 matching surfaces and 11-12 matching surfaces in the attached drawing 2b of the patent document), which are in close contact with each other, so that the male buckle, the female buckle and two adjacent floor boards can be locked in the horizontal direction and the vertical direction at the same time, otherwise, horizontal or vertical movement spaces exist between the two adjacent floor boards, and the use experience is reduced. After the male and female buckles are assembled, the floor buckle, especially the tongue groove portion of the female buckle, is always in a deformation state of expanding outward in multiple directions, and the male buckle is always in a deformation state of contracting inward in multiple directions, which requires that the male buckle and the female buckle on the floor block, especially the floor block, must have deformation capability (toughness) in multiple directions, so the floor buckle in the above patent documents is only suitable for the traditional wood floor at present, and the male buckle and the female buckle can only be of a wood structure with certain toughness.

2. Referring to the description of the above patent documents, fig. 2a and 2b, after the assembly is completed, the mating surfaces for limiting the upward displacement of the male buckle relative to the female buckle are provided and only on the head of the male buckle 10 and the upper groove wall of the male buckle groove 9, the mating surfaces 33 and 34. When the right floor block 1' is subjected to an upward external force or the left floor block 1 ″ is subjected to a downward external force, the head of the tenon 10 (compared with the root or other parts) is very easy to bend and deform downwards, and the female buckle part above the tenon groove 9 is thinner and is also easy to check and retract the upward bending and deformation, so that the left floor block and the right floor block move relatively in the vertical direction, and the user experience is reduced.

3. The male buckle and the female buckle of the structure are completely concentrated on the upper half part of the floor buckle in the limiting structures in the horizontal direction and the vertical direction, the structural strength of the lower half part of the male buckle and the lower half part of the female buckle is not effectively utilized, and the stress burden and the design difficulty of the upper half part of the floor buckle are increased.

2. The first horizontal surface of the tongue is arranged against the second horizontal surface of the tongue groove, which in turn restricts vertical downward movement of the first floorboard relative to the second floorboard. After the assembly is completed, the acting force exerted by the second inclined surface on the first inclined surface enables the male buckle to have a tendency of vertically moving downwards relative to the female buckle, and the tendency can enable the first horizontal surface and the second horizontal surface to be always pressed against each other naturally without special complex design on the structures and the positions of the first horizontal surface and the second horizontal surface. In terms of the design difficulty of the floor fastener on site, the mutual locking of the two floor blocks in the vertical and horizontal directions is realized by only three pairs of matching surfaces, which is obviously much easier than the mutual locking of the two floor blocks in the vertical and horizontal directions realized by four pairs of matching surfaces in the background patent.

3. The first horizontal surface is arranged at the root of the tenon, and the second horizontal surface is arranged at the notch of the tenon groove. In practice, the first horizontal surface is subjected mainly to upward pressure from the female snap and the second horizontal surface is subjected mainly to downward pressure from the male snap. By providing the first horizontal surface at the root of the tongue, the tongue will not deform or break significantly even if the first horizontal surface is subjected to a large upward pressure. Although the second horizontal surface is provided at the notch of the tongue groove, the female snap portion below the tongue groove has a larger thickness, and can completely withstand a large downward pressure without significant deformation or breakage.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings of the embodiments of the present application. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the application without any inventive step, are within the scope of protection of the application.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application belongs. The use of the terms "a" or "an" and the like in the description and in the claims of the present application do not denote a limitation of quantity, but rather denote the presence of at least one.

The "inner, outer, inner and outer sides" in the specification and claims of the present application are, unless otherwise specified, "inner and inner sides" in the horizontal direction near the center of the floor panel and "outer and outer sides" in the horizontal direction away from the center of the floor panel.

In the description of the present specification and claims, the terms "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present application and simplifying the description, but do not indicate or imply that the referred device or unit must have a specific direction, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.

Embodiments of the present application will now be described with reference to the accompanying drawings.

The first embodiment is as follows:

like conventional flooring systems, the flooring system of this embodiment also comprises a plurality of floor panels laid horizontally on the ground, each having a substantially rectangular outer contour and being provided with floor buckles on its sides, adjacent floor panels being connected to each other by means of the floor buckles on the sides.

Fig. 4 shows two adjacent floorboards in the flooring system, respectively a first floorboard a and a second floorboard b, which are arranged horizontally in fig. 4. The prior art cited in the background section of this application is: the side of the first floor block a is provided with a male buckle 1, and the side of the second floor block b is provided with a female buckle 2 matched with the male buckle 1. The male buckle 1 comprises a tongue 101 extending horizontally outwards, and the female buckle 2 comprises a tongue groove 201 recessed horizontally inwards and adapted to the tongue 101. As shown in fig. 6 and 7, the male and female snaps 1 and 2 are configured to be locked to each other by a forward rotation of the first floor panel a with respect to the second floor panel b, and the male and female snaps 1 and 2 are also configured to be released from each other by a reverse rotation of the first floor panel a with respect to the second floor panel b. And the male and female buttons 1 and 2 are engaged with each other and lock the first and second floor boards a and b in vertical and horizontal directions at the same time.

The key improvement of this embodiment lies in that above-mentioned public buckle 1 and female buckle 2 have adopted a brand-new cooperation structure, specifically as follows:

the tongue 101, which is an integral part of the male buckle, includes a vertical protrusion 1012 formed on the upper surface of the tongue and protruding upward: the tongue 101 obviously has its own surface structure, and the tongue 101 is formed by extending horizontally and outwardly from the body structure of the male buckle, so that the surface 1011 of the tongue 101 obviously comprises an upper surface and a lower surface, and the upper surface of the tongue is integrally provided with a vertical protrusion 1012 which is convex upwards.

The tongue groove 201, which is a component of the female buckle, includes a vertical sub-groove 2012 formed on the upper groove wall of the tongue groove and recessed upward: the tongue groove 201 obviously has a groove wall structure, and the tongue groove 201 is formed by extending horizontally inwards from (the surface of) the female buckle body structure, so the groove wall 2011 of the tongue groove 201 obviously comprises an upper groove wall and a lower groove wall, and the embodiment is integrally provided with an upward-concave vertical sub-groove 2012 at the upper groove wall.

The male buckle 1 comprises, in addition to the tongue 101 having the above-mentioned structure, a first inclined surface 1021 below the tongue 101 and having a low outer height and a high inner height: the male buckle 1 obviously has its own surface structure, the first inclined surface 1021 is a part of the surface of the male buckle 1, the first inclined surface 1021 is located below the first horizontal surface 1011a, and the first inclined surface 1021 has a low outer side and a high inner side. The specific meaning of "inside and outside" has been explained above, and the term "low outside and high inside" means: a side of the first beveled surface 1021 that is distal from the center portion of the first panel (which may be referred to as an outer side of the first beveled surface 1021) has a height that is less than a height of a side of the first beveled surface 1021 that is proximal to the center portion of the first panel (which may be referred to as an inner side of the first beveled surface 1021).

Correspondingly, the female snap 2 comprises, in addition to the tongue groove 201 having the above-mentioned structure, a second inclined surface 2021 which is located below the tongue groove 201 and has a high outer side and a low inner side: the female snap 2 obviously has its own surface structure, the second inclined surface 2021 is a part of the surface of the female snap, and the inclined direction of the second inclined surface 2021 is higher outside and lower inside. The term "high outside and low inside" means: the height of the side of the second slanted surface 2021 away from the central portion of the second panel (which may be referred to as the outer side of the second slanted surface 2021) is higher than the height of the side of the second slanted surface 2021 near the central portion of the second panel (which may be referred to as the inner side of the first slanted surface 1021).

The upwardly projecting vertical projection 1012 obviously has an inside surface near the center of the first floorboard and an outside surface away from the center of the first floorboard. The upwardly recessed vertical subslot 2012 obviously has an inside surface near the center of the second floorboard and an outside surface near the center of the second floorboard.

In fig. 4, after the male buckle 1 of the first floor board a and the female buckle 2 of the second floor board b are locked with each other, the tongue 101 of the male buckle 1 extends into the tongue groove 201 of the female buckle 2, and the vertical protrusion 1012 on the tongue 101 extends into the vertical sub-groove 2012 in the tongue groove 201. The inside surface 1012a of the vertical protrusion 1012 is disposed against the outside groove wall surface 2012a of the vertical subslot 2012, thereby restricting the first floor panel a and the second floor panel b from moving away from each other in the horizontal direction: the first floor panel a cannot move away from the second floor panel b in the horizontal direction. The first and second beveled surfaces 1021, 2021 are disposed against each other, thereby restricting both the first and second floor panels a, b from approaching each other in the horizontal direction, and the first floor panel a from moving vertically upward relative to the second floor panel b: the first floor panel a cannot move close to the second floor panel b in the horizontal direction nor move upward vertically with respect to the second floor panel b.

To ensure that the male and female snaps are locked together, the inner side surface 1012a of the vertical protrusion 1012 abuts against the outer side groove wall 2012a of the vertical sub-groove 2012, and the first inclined surface 1021 abuts against the second inclined surface 2021, which is easily accomplished: as long as the inner side wall of the vertical protrusion 1012, or the outer side groove wall of the vertical sub-groove 2012, or the first inclined surface 1021 part of the male buckle 1, or the second inclined surface 2021 of the female buckle has certain flexibility (or deformation capability), after the assembly is completed, the male buckle is subjected to a pair of left-right direction tensile forces in FIG. 4, one acts on the first inclined surface leftwards, and the other acts on the inner side wall of the vertical protrusion 1012 rightwards.

It can be seen that only under the abutting cooperation action of the two pairs of matching surfaces, namely the inner side surface 1012a of the vertical protrusion 1012 and the outer side groove wall surface 2012a of the vertical sub-groove 2012, and the first inclined surface 1021 and the second inclined surface 2021, the two floor boards are limited from moving away from and approaching to each other in the horizontal direction (specifically, in the horizontal direction perpendicular to the butt edge of the two floor boards), and meanwhile, the first floor board is limited from moving upwards in the vertical direction, and the two floor boards can be locked in three directions only by the two pairs of matching surfaces, which is very ingenious.

Therefore, in the embodiment, by skillfully designing the structures of the male buckle and the female buckle, after the adjacent floor blocks are locked and connected, the adjacent floor blocks can not be far away from each other or close to each other in the horizontal direction, and the first floor block can not move upwards relative to the second floor block in the vertical direction. However, the vertical downward movement of the first floor board is not limited. Based on this, this embodiment has further optimized the structure of public buckle 1 and female buckle 2:

the tongue 101 as an integral part of the male buckle 1 further comprises a first horizontal surface 1011a formed on the lower surface of the tongue, the first horizontal surface 1011a being a part of the lower surface of the tongue, and the tongue groove 201 as the tongue groove 201 further comprises a second horizontal surface 2011a formed on the lower groove wall of the tongue groove, the second horizontal surface 2011a being a part of the lower groove wall of the tongue groove. After assembly, the aforementioned first horizontal surface 1011a is placed against the second horizontal surface 2011a, which in turn restricts vertical downward movement of the first floor panel a relative to the second floor panel b.

Through simple force analysis, the following can be known: the first inclined surface 1021 on the male buckle 1 and the second inclined surface 2021 on the female buckle 2 are arranged obliquely in a specific direction, and after the assembly is completed, the first inclined surface 1021 and the second inclined surface 2021 abut against each other to produce the effect: the (obliquely downward) force exerted by second inclined surface 2021 on first inclined surface 1021 causes male buckle 1 to have a tendency to move vertically downward relative to female buckle 2, which in turn causes first horizontal surface 1011a and second horizontal surface 2011a to press against each other. Assuming that the first horizontal surface 1011a and the second horizontal surface 2011a are vertically spaced by a gap just after the male and female buckles are connected, the first inclined surface 1021 and the second inclined surface 2021 are pressed against each other, so that the male buckle 1 moves downward by the force applied by the second inclined surface 2021 to the first inclined surface 1021, and the first horizontal surface 1011a and the second horizontal surface 2011a approach each other and abut against each other.

It can be seen that under the abutting cooperation of the three pairs of matching surfaces, namely, the inner side surface 1012a of the vertical protrusion 1012 and the outer side groove wall 2012a of the vertical sub-groove 2012, the first inclined surface 1021 and the second inclined surface 2021, and the first horizontal surface 1011a and the second horizontal surface 2011a, the two floor blocks are simultaneously limited from moving away from and approaching to each other in the horizontal and vertical directions. In terms of the design difficulty of the floor fastener on site, the mutual locking of the two floor blocks in the vertical and horizontal directions is realized by only three pairs of matching surfaces, which is obviously much easier than the mutual locking of the two floor blocks in the vertical and horizontal directions realized by four pairs of matching surfaces in the background patent. And the mutual abutting of one pair of matching surfaces is naturally realized by the opposite abutting action of the other two pairs of matching surfaces.

The term "abutting arrangement" as used in the specification and claims of the present application may be a partial abutting or a full-area abutting. Obviously, as long as the inner side surface 1012a of the vertical protrusion 1012 and the outer side groove wall 2012a of the vertical sub-groove 2012 have abutting contact portions, the first horizontal surface 1011a and the second horizontal surface 2011a have abutting contact portions, and the first inclined surface 1021 and the second inclined surface 2021 have abutting contact portions, the two floor blocks can be locked in the horizontal and vertical directions. Compared with full-area abutting and local abutting, the manufacturing precision requirement of the male buckle and the female buckle is lower. The term "horizontal" in the description and claims of the present application should not be construed narrowly as being perfectly parallel to the horizontal plane, but rather as: "substantially horizontal" with an angle of 30 ° to the horizontal; the term "vertical" in the present description and claims is also not to be understood narrowly as being completely perpendicular to the horizontal plane, but rather as: "substantially vertical" with an angle in the range of 30 ° to the vertical.

As mentioned before, the first horizontal surface 1011a is part of the surface 1011 of the tongue 101. Whereas the vertical protrusion 1012 is part of the tongue 101, the inner side surface 1012a of the vertical protrusion 1012 is naturally also part of the surface 1011 of the tongue 101. It was also mentioned before that the first horizontal surface 1011a as a tongue surface component and the inner side surface 1012a of the vertical protrusion 1012 as a tongue surface component are arranged against the groove wall 2011 of the tongue groove 201 (in particular the second horizontal surface 2011a and the outer side groove wall 2012a of the vertical sub-groove 2012) to lock the connection of the two floor panels. Then is the surface structure of the tongue 101 at other locations in this embodiment disposed against the groove wall 2011 of the tongue groove 201? The answer is negative: the tongue surfaces at all locations except the first horizontal surface 1011a and the inside surface 1012a of the vertical protrusion 1012 are arranged with a gap D from the groove wall surface 2011 of the tongue groove 201. In other words: the remaining surfaces of the tongue 101, except for the first horizontal surface 1011a and the inside surface 1012a of the vertical protrusion 1012, are separated from the groove wall 2011 of the tongue groove 201 by a gap D. Therefore, the floor buckle, particularly the design size requirement of the tongue piece and the tongue piece groove is low, and the male buckle and the female buckle are convenient to connect and assemble.

Of course, it is also possible to arrange the tongue part extending into the tongue groove against the full area of the groove wall of the tongue groove, which however places high demands on the deformability of the male and female snap.

In this embodiment, the first inclined surface 1021 and the second inclined surface 2021 are both planar, and the included angle between the first inclined surface 1021 and the second inclined surface 2021 of the planar structure and the horizontal plane should not be too large or too small. If the included angle is too large, the upward locking force for the first floor block a is not enough, so that the first floor block a is easy to move upwards. If the included angle is too small, the thicknesses of the heads at the bottoms of the male buckle 1 and the female buckle 2 are small, and the male buckle and the female buckle are easy to break under vertical external force. Generally, the angle is preferably in the range of 30-85 degrees, and in this embodiment, the angle between the first inclined surface 1021 and the horizontal plane and the angle between the second inclined surface 2021 and the horizontal plane are both 75 degrees.

In this embodiment, the first horizontal surface 1011a is disposed at the root of the tongue 101, and the second horizontal surface 2011a is disposed at the notch of the tongue groove 201. In practical application, first horizontal surface 1011a is mainly subjected to upward pressure from female buckle 2, and second horizontal surface 2011a is mainly subjected to downward pressure from male buckle 1. By providing the first horizontal surface 1011a at the root of the tongue 101, the tongue 101 will not deform or break significantly even if the first horizontal surface 1011a is subjected to a large upward pressure. Although the second horizontal surface 2011a is disposed at the notch of the tongue groove 201, the female snap portion below the tongue groove has a larger thickness, and can fully bear a large downward pressure without significant deformation or fracture.

In the present embodiment, the first inclined surface 1021 extends to the bottom of the male buckle 1, and the second inclined surface 2021 extends to the bottom of the female buckle 2. Although the abutting areas of the first inclined surface 1021 and the second inclined surface 2021 can be increased, and the locking strength of the male and female buckles in the horizontal and vertical directions is further improved, strict requirements are imposed on the manufacturing precision of the male and female buckles, otherwise it is difficult to ensure that three pairs of matching surfaces, namely the inner side surface 1012a and the vertical sub-groove 2012, the first horizontal surface 1011a and the second horizontal surface 2011a, and the first inclined surface 1021 and the second inclined surface 2021 abut perfectly after the assembly is completed. However, the following second embodiment subtly solves this problem.

In order to reduce the size and material consumption of the male and female buckles as much as possible, the embodiment arranges the vertical protrusion 1012 at the outer end of the tongue 101, and arranges the vertical sub-groove 2012 as close as possible to the groove bottom of the tongue groove 201 — the inner groove wall 2012a of the vertical sub-groove 2012 is formed on the groove bottom wall 201a of the tongue groove 201.

In the present embodiment, the first floor board a and the second floor board b are not a traditional wood floor structure, but a composite structure formed by combining the aluminum honeycomb plate 4 of the lower layer and the marble panel 5 adhered and fixed on the upper surface of the aluminum honeycomb plate, specifically as follows:

the aluminum honeycomb plate 4 is composed of an upper aluminum plate 401, a lower aluminum plate 402 arranged in parallel below the upper aluminum plate, and an aluminum honeycomb core layer 403 fixedly connected between the upper aluminum plate and the lower aluminum plate. The area of aluminum honeycomb core layer 403 will be less than the area of upper aluminum plate 401 and lower aluminum plate 402, and every side of aluminum honeycomb core layer 403 is in the inboard of upper aluminum plate 401 and the corresponding side of lower aluminum plate 402 to it inlays dress clearance 4a to have formed the floor buckle that is located around aluminum honeycomb core layer 403 between upper aluminum plate 401 and lower aluminum plate 402. The floor buttons are fitted into the floor button fitting gaps 4 a. The floor buckle portion fitted into the floor buckle fitting gap 4a is bonded and fixed to the upper aluminum plate 401 and the lower aluminum plate 402.

The marble panel 5 on the upper layer can also be replaced by a board structure made of other materials such as a wood board, a ceramic tile board, a plastic board and the like.

It can be seen that the male and female snaps 1 and 2, which are the floor snaps in this embodiment, are not integrally formed with the body portion of the floor board. The male buckle 1 and the female buckle 2 which are separately connected with the floor block body can be made of various materials, in the embodiment, the male buckle 1 and the female buckle 2 are made of aluminum alloy materials and are integrally formed. Further, the aforementioned male buckle 1 and female buckle 2 are both made of aluminum alloy section. In some other embodiments of the present application, the male buckle 1 and the female buckle 2 may also be formed as an integral molding of plastic material, and they are formed by injection molding respectively.

In still other embodiments of the present application, the male or female buckles 1, 2 may be integrally formed at the side positions of the floor boards, i.e. the buckles may be integrally made with the floor boards as an integral structure. For example, the male buckle 1 or the female buckle 2 is a wood structure integrated with the floor block body.

In addition, in this embodiment, a horizontal inwardly recessed weather strip embedding groove 103 is further provided above the tongue 101, and a lower groove wall 1031 of the weather strip embedding groove 103 is formed on the tongue 101, and the weather strip 3 is embedded in the weather strip embedding groove 103. After the male and female buckles are locked and matched, the sealing strip 3 embedded in the sealing strip caulking groove 103 is horizontally clamped between the male buckle 1 and the female buckle 2, so that the matching gap between the male buckle and the female buckle is completely blocked, and water above the floor system is prevented from permeating into the lower part of the floor system downwards through the gap at the joint and matching part of the floor blocks.

Referring to fig. 1, 2 and 4 again, in practice, the side of the first floor block a is provided with not only the male snap 1 but also the female snap 2, and the male snap and the female snap on the first floor block a are respectively arranged on different sides of the first floor block. Similarly, the side of the second floor b is provided with not only the female buckle 2 but also the male buckle 1, and the male buckle and the female buckle on the second floor b are respectively arranged on different sides of the second floor. Thus, it is possible to continue to couple a third floor panel to the left side of the first floor panel a and a fourth floor panel to the right side of the second floor panel b.

Example two:

fig. 8 to 10 show a second embodiment of the flooring system of the present application, which is substantially identical in structure to the first embodiment, with the main differences:

in this embodiment, the first inclined surface 1021 does not extend all the way to the bottom of the male buckle 1, and the second inclined surface 2021 does not extend all the way to the bottom of the female buckle 2.

By way of example one we know that: the male snap 1 has its own surface structure and a part of the surface 102 of the male snap 1 is under the tongue 101, and the first inclined surface 1021 is not only an integral part of the male snap surface but also under the tongue 101.

In this embodiment, all surfaces 102 of the male buckle 1 except the first inclined surface 1021 and below the tongue 101 are arranged with a gap D from the surface 202 of the female buckle 2.

Compared with the first embodiment, the first inclined surface 1021 and the second inclined surface 2021 are shortened in the first embodiment, which is more beneficial to the manufacture and assembly of the male and female buckles.

The above are exemplary embodiments of the present application only, and are not intended to limit the scope of the present application, which is defined by the appended claims.
