Description

TECHNICAL FIELD

[0001] The present application relates to the field of floor, in particular to a floor system and a vertical dismountable floor buckle. BACKGROUND

[0002] The patent No. CN201780059362.X discloses a floor buckle structure which connects two adjacent floor blocks together by vertical displacement, and the two floor blocks are locked in vertical and horizontal directions after assembly.

[0003] The structure which connects two floor blocks together by vertical displacement not only reduces the difficulty of floor block assembly, but also has lower requirements for space, especially horizontal space, and is very practical.

[0004] However, the floor buckle structure in the above patent has the following defects:

[0005] After the side edges of the two floor blocks are connected by the male and female buckles, the two floor blocks can only be separated by rotating one of them downward. However, the floor installed on the ground does not have the space to rotate downward, so when this buckle structure is applied to the floor system, it is easy to install but difficult to disassemble.

[0006] The present application is thus derived. SUMMARY

[0007] The technical problem to be solved by the present application is to provide a floor system and a vertical dismountable floor buckle which are simple and ingenious in structure and can lock and separate the side edges of two floor blocks by vertical displacement.

[0008] The technical scheme of the present application is:

[0009] A floor system, comprising a first floor block and a second floor block arranged horizontally, a side edge of the first floor block is provided with a male buckle, a side edge of the second floor block is provided with a female buckle matched with the male buckle, the male buckle and the female buckle are configured to be locked by vertical downward displacement of the first floor block relative to the second floor block and to be separated by vertical upward displacement of the first floor block relative to the second floor block, the male buckle comprises an upwardly recessed vertical tongue slot and a horizontally inwardly recessed horizontal tongue slot, the female buckle comprises a vertically upwardly protruding vertical tongue and a horizontally outwardly protruding elastic horizontal tongue, the vertical tongue is embedded in the vertical tongue slot to lock the first floor block and the second floor block in the horizontal direction, and the elastic horizontal tongue is embedded in the horizontal tongue slot to elastically lock the first floor block and the second floor block in the vertical direction.

[0010] The application further comprises the following preferred schemes on the basis of the above technical scheme.

[0011] The female buckle comprises a spring arm extending downward and a deformation seam inside the spring arm, and the elastic horizontal tongue is integrally formed at the lower end of the spring arm.

[0012] The female buckle comprises a spring arm extending upward and a deformation seam inside the spring arm, and the elastic horizontal tongue is integrally formed at the upper end of the spring arm.

[0013] The female buckle comprises:

[0014] a spring arm extending vertically and fixedly connected with the female buckle body at both ends, and

[0015] a deformation seam inside the spring arm;

[0016] The elastic horizontal tongue is integrally formed at the middle part of the spring arm.

[0017] The elastic horizontal tongue and the vertical tongue are separated by a certain distance in the horizontal direction, and the floor system further comprises a sealing strip vertically clamped by the male buckle and the female buckle and located between the elastic horizontal tongue and the vertical tongue.

[0018] The lower half of the outer side surface of the elastic horizontal tongue is an outer-higher-inner-lower guide slope, and the upper half of the outer side surface of the elastic horizontal tongue is an outer-lower-inner-higher guide slope.

[0019] The lower side groove wall surface of the horizontal tongue slot is an outer-lower-inner-higher guide slope, and the outer surface of the male buckle directly below the horizontal tongue slot is an outer-higher-inner-lower guide slope.

[0020] The second floor block is a wooden floor block, the female buckle comprises a wooden female buckle body integrated with the body structure of the second floor block, and the spring arm with the elastic horizontal tongue is a metal or plastic piece fixedly connected in the female buckle body.

[0021] The side edge of the first floor block is further provided with a female buckle, and the side edge of the second floor block is provided with a male buckle.

[0022] The elastic horizontal tongue and the vertical tongue are separated by a certain distance in the horizontal direction, and during the vertical assembly of the first floor block and the second floor block, when the male buckle contacts the elastic horizontal tongue, the outer side groove wall surface of the vertical tongue slot and the inner side surface of the vertical tongue abut each other.

[0023] A vertical dismountable floor buckle comprises a male buckle and a female buckle which are matched, and are locked with each other by vertical downward movement of the male buckle relative to the female buckle, and are unlocked with each other by vertical upward movement of the male buckle relative to the female buckle, the male buckle comprises an upwardly recessed vertical tongue slot and a horizontally inwardly recessed horizontal tongue slot, the female buckle comprises a vertical tongue which is upwardly protruded and a horizontal tongue which is horizontally outwardly protruded and is elastic, the vertical tongue is embedded in the vertical tongue slot to lock the male buckle and the female buckle in horizontal direction, and the elastic horizontal tongue is embedded in the horizontal tongue slot to elastically lock the male buckle and the female buckle in vertical direction.

[0024] The present application can realize the following beneficial effects:

[0025] 1. In the floor system of the present application, the male and female floor buckles arranged at the side edges of the adjacent floor blocks are locked and separated by vertical displacement, which facilitates the assembly and connection of the floor blocks, and can conveniently vertically dismount any floor block which is locked with the adjacent floor block by the male buckle from the floor system.

[0026] 2. After the corresponding side edges of the adjacent floor blocks are connected by the floor buckles of the present application, the two floor blocks are rigidly locked in horizontal direction and in vertical direction, so that even if a great horizontal force is applied to the floor blocks, the adjacent floor blocks cannot be dismounted, and only if a vertical upward force is applied to the floor blocks by a special tool, the adjacent floor blocks can be dismounted, which is exactly suitable for the use environment of the floor: when the floor system is normally used, the floor blocks are mainly subjected to vertical downward pressure and occasionally subjected to a great horizontal thrust, however, the aforementioned vertical downward pressure and horizontal thrust cannot cause the floor blocks to separate from each other, and the vertical upward pulling force which can cause the floor blocks to separate from each other does not occur when the floor system is normally used.

[0027] 3. When the floor blocks are wooden floor blocks, the female buckle body is directly and integrally processed at the side edge position of the main body of the wooden floor block during the manufacture of the main body of the wooden floor block, and then the elastic arm made of metal or plastic material and provided with the elastic horizontal tongue is fixedly connected in the female buckle body, so that the floor buckle of the present application is also applicable to the wooden floor.

[0028] 4. During the vertical assembly of the adjacent two floor blocks, when the elastic horizontal tongue on the male buckle and the female buckle is in contact and is about to be deformed under pressure, the outer side groove wall surface of the vertical tongue slot and the inner side surface of the vertical tongue are in abutment with each other. In this way, when the male buckle continues to move downward and the elastic arm and the elastic horizontal tongue are deformed inwardly, the horizontal thrust exerted by the elastic arm on the male buckle is resisted by the vertical tongue, and the installer does not need to exert a horizontal thrust on the first floor block which is directed to the second floor block, thereby further reducing the installation difficulty of the two floor blocks.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme of the embodiments of the application will be described clearly and completely below with reference to the drawings of the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments of the application. Based on the described embodiments of the application, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the application.

[0049] Unless otherwise defined, the technical terms or scientific terms used herein should be understood as the usual meanings understood by a person with ordinary skills in the art to which the application belongs. The "one" or "a" and similar words used in the patent application specification and claims of the application do not represent quantity limitation, but represent the existence of at least one.

[0050] The "inner", "outer", "inner side" and "outer side" mentioned in the specification and claims of the application, if not specifically stated, are "inner", "inner side" in the horizontal direction close to the center of the floor block, and "outer", "outer side" in the horizontal direction away from the center of the floor block.

[0051] In the description and claims of the application, and where first and second, top and bottom, over and under, and other like terms are used, these terms are used for facilitating the description and are not intended to limit or in any way suggest the particular orientation or configuration of the apparatus or system described, unless otherwise indicated. Thus, these terms are used interchangeably and are intended to convey the same meaning.

[0052] Embodiments of the present application will now be described, by way of example only, with reference to the accompanying drawings.

[0053] Embodiment one:

[0054] Similar to the conventional floor system, the floor system of the present embodiment also comprises a plurality of floor panels horizontally laid on the ground, each floor panel has a substantially rectangular outer contour, and each floor panel is provided with floor fasteners on its side edges, and the adjacent floor panels are connected to each other by means of the floor fasteners on the side edges.

[0055] Figure 1 Two adjacent floor panels in the floor system are shown, which are a first floor panel a and a second floor panel b, the side edge of the first floor panel a is provided with a male fastener 1, and the side edge of the second floor panel b is provided with a female fastener 2 which is adapted to the male fastener 1, the male fastener 1 and the female fastener 2 are configured to be locked to each other by vertically moving the first floor panel a downward relative to the second floor panel b, and the male fastener 1 and the female fastener 2 are also configured to be unlocked from each other by vertically moving the first floor panel a upward relative to the second floor panel b.

[0056] The key improvement of the present embodiment is that the male fastener 1 comprises an upwardly recessed vertical tongue slot 101 and a horizontally inwardly recessed horizontal tongue slot 102, and the female fastener 2 comprises a vertically upwardly protruding vertical tongue 201 and a horizontally outwardly protruding elastic horizontal tongue 202. The vertical tongue 201 is embedded in the vertical tongue slot 101, thereby locking the first floor panel a and the second floor panel b in the horizontal direction. The elastic horizontal tongue 202 is embedded in the horizontal tongue slot 102, thereby elastically locking the first floor panel a and the second floor panel b in the vertical direction.

[0057] The so-called "elastic horizontal tongue" does not specifically refer to the fact that the horizontal tongue itself has the ability of elastic deformation, but rather: the "elasticity" of the horizontal tongue can come from the horizontal tongue itself, or from other structures connected to the horizontal tongue and the female fastener body (such as the following elastic arm in the present embodiment). In this way, when the horizontal tongue is subjected to a force in a specific direction (vertical direction), it will produce a "displacement deformation", and after the aforementioned force is eliminated, the "displacement deformation" will recover. The aforementioned "displacement deformation" can be the displacement of the entire horizontal tongue, or the deformation and local displacement of the horizontal tongue itself. In the present embodiment, the following structure is adopted:

[0058] The female fastener 2 further comprises a downwardly protruding elastic arm 203 and a deformation gap 204 located inside the elastic arm, and the elastic horizontal tongue 202 is integrally formed at the lower end of the elastic arm 203.

[0059] In the embodiment, the elastic horizontal tongue 202 is horizontally spaced apart from the vertical tongue 201 and is located at the inner side of the vertical tongue 201. Correspondingly, the horizontal tongue slot 102 is horizontally spaced apart from the vertical tongue slot 101 and is located at the outer side of the vertical tongue slot 101. In some other embodiments of the application, the elastic horizontal tongue 202 can also be located at the outer side of the vertical tongue 201, and correspondingly, the horizontal tongue slot 102 is located at the inner side of the vertical tongue slot 101. The horizontal tongue slot 102 and the vertical tongue slot 101 and the elastic horizontal tongue 202 and the vertical tongue 201 are arranged horizontally (specifically, vertically to the connecting edge of the two floor blocks) to facilitate the manufacturing and vertical assembly of the male and female buckles, and the sealing strip can also be very conveniently clamped between the male and female buckles to prevent water, as will be described in Embodiment 3.

[0060] Referring to Figures 1 to 6 As shown in FIG. 1, in the assembly process, the upper half of the outer side of the male buckle 1 on the first floor block a abuts against the upper half of the outer side of the female buckle 2 on the second floor block b and moves vertically downward. The elastic horizontal tongue 202 on the female buckle 2 moves inward under the extrusion of the upper half of the outer side of the male buckle 1, and the elastic arm 203 is compressed (the elastic horizontal tongue 202 is directly compressed) and deformed inward at the lower end. When the horizontal tongue slot 102 moves to the position of the elastic horizontal tongue 202, the elastic horizontal tongue 202 is not compressed, the elastic arm 203 restores the deformation, the elastic horizontal tongue 202 moves outward and is embedded in the horizontal tongue slot 102, and the elastic locking of the male buckle 1 and the female buckle 2 in the vertical direction is achieved. At this time, the vertical tongue 101 of the female buckle 2 is embedded in the vertical tongue slot 101 of the male buckle 1, and the rigid locking of the male buckle 1 and the female buckle 2 in the horizontal direction is achieved.

[0061] When the first floor block a and the second floor block b need to be separated, a negative pressure suction cup adsorbed on the upper surface of the first floor block a can be used to apply an upward force to the first floor block a, the elastic horizontal tongue 202 is directly compressed, the elastic arm 203 is compressed and deformed inward at the upper end, and the elastic horizontal tongue 202 moves inward and is separated from the horizontal tongue slot 102.

[0062] Referring to Figure 6 As shown in FIG. 1, in order to facilitate the vertical locking and separation of the male buckle 1 and the female buckle 2 (i.e., the vertical locking and separation of the first floor block a and the second floor block b), the lower half 202a of the outer side of the elastic horizontal tongue 202 is provided as a guide inclined surface with high outer side and low inner side, and the upper half 202b of the outer side of the elastic horizontal tongue 202 is provided as a guide inclined surface with low outer side and high inner side. During the vertical assembly and separation of the two floor blocks, the vertical extrusion force on the elastic horizontal tongue 202 is converted into horizontal extrusion force (horizontal component force) under the action of the aforementioned guide inclined surface, so that the elastic arm 203 is more easily deformed.

[0063] Further, the upper half 202a and the lower half 202b of the outer side surface of the elastic tongue 202 are both circular arc surfaces with a certain smoothness. Further, the two circular arc surfaces are concentric, so that the outer side surface of the elastic tongue 202 is a circular arc surface as a whole.

[0064] In order to better guide the elastic tongue 202 to be embedded in the tongue embedding groove 102 and to be pulled out of the tongue embedding groove 102 (when the first floor block is subjected to a large enough pulling force), the lower groove wall surface 102a of the tongue embedding groove 102 on the male buckle 1 is designed as a guide inclined surface with the outer side being lower and the inner side being higher, and the outer surface 103 of the male buckle 1 directly below the tongue embedding groove 102 is designed as a guide inclined surface with the outer side being higher and the inner side being lower. Further, the lower groove wall surface of the tongue embedding groove 102 and the outer surface 103 of the male buckle 1 directly below the tongue embedding groove are both circular arc surfaces.

[0065] In the embodiment, each floor buckle is an integrally formed member and is made of aluminum alloy profile. The floor buckle can also be made of other materials, such as an integrally formed plastic member.

[0066] Of course, the male buckle 1 or the female buckle 2 can also be designed as a split structure assembled by multiple components.

[0067] In the embodiment, each floor block (including the first and second floor blocks) is not a traditional wooden floor block or a marble or ceramic tile floor block, but a composite structure mainly formed by the lower honeycomb aluminum plate 3 and the upper wooden panel 4 fixedly bonded to each other, and the floor buckle is fixedly bonded to the side edge position of the honeycomb aluminum plate 3.

[0068] The wooden panel 4 can also be replaced by a marble panel, a ceramic tile panel or a plastic panel. The honeycomb aluminum plate 3 is composed of an upper aluminum plate 301, a lower aluminum plate 302 arranged in parallel below the upper aluminum plate, and an aluminum honeycomb core layer 303 fixedly connected between the upper aluminum plate and the lower aluminum plate. The area of the aluminum honeycomb core layer 303 is smaller than the area of the upper aluminum plate 301 and the lower aluminum plate 302, and each side edge of the aluminum honeycomb core layer 303 is located inside the corresponding side edge of the upper aluminum plate 301 and the lower aluminum plate 302, so that a floor buckle embedding gap 3a is formed between the upper aluminum plate 301 and the lower aluminum plate 302 around the aluminum honeycomb core layer 303. Each floor buckle is embedded in the floor buckle embedding gap 3a. Moreover, the part of the floor buckle embedded in the floor buckle embedding gap 3a is fixedly bonded to the upper aluminum plate 301 and the lower aluminum plate 302.

[0069] Referring again to Figure 10As shown, the side edges of the first floor block a are not only provided with the male buckle 1 of the above structure, but also provided with the female buckle 2 of the above structure, and the male buckle and the female buckle on the first floor block a are respectively arranged on different side edges of the first floor block. Similarly, the side edges of the second floor block b are not only provided with the female buckle 2 of the above structure, but also provided with the male buckle 1 of the above structure, and the male buckle and the female buckle on the second floor block b are respectively arranged on different side edges of the second floor block. In this way, the third floor block c can be connected on the other side of the first floor block a, and the fourth floor block d can be connected on the other side of the second floor block b, as shown in Figure 11

[0070] Embodiment Two:

[0071] Figure 11 A second specific embodiment of the floor system of the present application is shown, which has a structure basically the same as that of the first embodiment, and the difference is only that:

[0072] In this embodiment, the elastic arm 203 of the female buckle 2 extends upward instead of downward, and the elastic tongue 202 is integrally formed on the upper end of the elastic arm 203 instead of the lower end.

[0073] Embodiment Three:

[0074] Figure 12 A third specific embodiment of the floor system of the present application is shown, which has a structure basically the same as that of the first embodiment, and the difference is only that:

[0075] In this embodiment, the elastic arm 203 of the female buckle 2 extends vertically, and both ends of the elastic arm 203 are integrally connected with the female buckle body, and the elastic tongue 202 is integrally formed on the middle part of the elastic arm 203.

[0076] It should be noted that the "upper end, lower end, and middle part" of the elastic arm in the claims and the specification of the present application should not be understood in a narrow sense. The "upper end" should not be limitedly interpreted as the upper end point position of the elastic arm, the "lower end" should not be limitedly interpreted as the lower end point position of the elastic arm, and the "middle part" should not be limitedly interpreted as the geometric midpoint of the length dimension of the elastic arm. Generally speaking, if the length of the elastic arm is divided into three sections, then each part of the upper section can be called the upper end of the elastic arm, each part of the lower section can be called the lower end of the elastic arm, and each part of the middle section can be called the middle part of the elastic arm.

[0077] Embodiment Four:

[0078] Figure 13 A fourth specific embodiment of the floor system of the present application is shown, which has a structure basically the same as that of the first embodiment, and the difference is only that:

[0079] In this embodiment, a sealing strip 5 is arranged at the matching position of the male buckle 1 and the female buckle 2.​

[0080] The sealing strip 5 is arranged between the elastic horizontal tongue 202 and the vertical tongue 201, and is vertically clamped by the male buckle 1 and the female buckle 2. In this way, water above the floor system can be prevented from penetrating into the floor system below through the gap between the connected and fitted floor blocks.

[0081] Embodiment Five

[0082] Figures 14 to 16 A fifth specific embodiment of the floor system of the present application is shown, which is similar to the structure of the first embodiment, and the only difference is that:

[0083] In this embodiment, the body part of each floor block is made of wood, commonly known as wood floor or wood floor block, including solid wood floor, reinforced wood floor, solid wood composite floor, multi-layer composite floor, bamboo floor and softwood floor, and is no longer a composite structure of honeycomb base plate and wood panel. The body part of the female buckle 2 is made of wood material integrated with the body of the floor block - the female buckle body is directly and integrally processed at the side edge position of the body of the floor block at the same time of manufacturing the body part of the wood floor block. Then the elastic arm 203 with the elastic horizontal tongue 202 is fixedly connected in the wooden female buckle body, and the elastic arm with the elastic horizontal tongue is preferably made of metal or plastic with certain deformation ability and high structural strength. The male buckle 1 is integrally made with the body part of the floor block, i.e. the male buckle 1 is entirely of wood structure and is integrated with the body structure of the floor block, and the male buckle 1 is directly and integrally processed at the side edge position of the body of the floor block at the same time of manufacturing the body part of the wood floor block.

[0084] Embodiment Six

[0085] Figure 17 A sixth specific embodiment of the floor system of the present application is shown, which is similar to the structure of the first embodiment, and the main difference is that:

[0086] In this embodiment, during the vertical assembly of the male and female buckles, i.e. the vertical assembly of the first floor block a and the second floor block b, when the male buckle 1 contacts the elastic horizontal tongue 202, the outer side wall surface 101a of the vertical tongue slot 101 abuts against the inner side surface 201a of the vertical tongue 201. In this way, when the male buckle 1 continues to move downward and the elastic arm and the elastic horizontal tongue deform inward, the horizontal pushing force exerted by the elastic arm and the elastic horizontal tongue on the male buckle 1 is resisted by the vertical tongue 201, and the installer does not need to exert a horizontal pushing force on the first floor block a towards the second floor block, further reducing the installation difficulty of the two floor blocks.

[0087] That is, when the elastic arm and the elastic horizontal tongue are about to be compressed and deformed, the vertical tongue 201 cooperates with the vertical tongue slot 101 to form vertical guidance.

[0088] The above merely provides exemplary embodiments of the present application, but not for limiting the protection scope of the present application, which is defined by the appended claims.
