Description

TECHNICAL FIELD

[0001] The present application relates to the field of floor, in particular to a floor system and a vertical dismounting type 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 dismounting type 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 movement of the first floor block relative to the second floor block and to be separated by vertical upward movement of the first floor block relative to the second floor block, the male buckle comprises an upwardly recessed vertical tongue slot and a horizontally outwardly protruding elastic horizontal tongue, the female buckle comprises an upwardly protruding vertical tongue and a horizontally inwardly recessed horizontal tongue slot, 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 male 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 male 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 male buckle comprises:

[0014] a spring arm extending vertically and fixedly connected to both ends of the male buckle, 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 horizontal tongue slot is horizontally separated from the vertical tongue by a certain distance, and the floor system further comprises a sealing strip vertically clamped by the male buckle and the female buckle and located between the horizontal tongue slot 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 upper side wall surface of the horizontal tongue slot is an outer-higher-inner-lower guide slope.

[0020] The first floor block comprises a wooden floor block body, the male buckle comprises a male buckle body in an integral structure with the floor block body, and the spring arm with the elastic horizontal tongue is a metal or plastic piece fixedly connected in the male buckle body.

[0021] A vertically detachable floor buckle comprises a male buckle and a female buckle matched with each other, and the male buckle and the female buckle are configured to be locked with each other by vertically moving the male buckle downward relative to the female buckle and to be unlocked with each other by vertically moving the male buckle upward relative to the female buckle. The male buckle comprises a vertical tongue slot recessed upward and an elastic horizontal tongue extending horizontally outward, and the female buckle comprises a vertical tongue extending upward and a horizontal tongue slot recessed horizontally inward. 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.

[0022] The application can achieve the following beneficial effects:

[0023] 1. In this flooring system, the male and female floor clips located on the sides of adjacent floorboards are designed to lock and separate by vertical displacement. This not only facilitates the assembly and connection of floorboards, but also makes it very convenient to vertically remove any floorboard that is locked to an adjacent floorboard only by the male clip from the flooring system.

[0024] 2. By using the floor clips of this application to connect the corresponding sides of adjacent floor tiles, rigid locking in both the horizontal and vertical directions is achieved. This makes it impossible to separate adjacent floor tiles even if a large horizontal force is applied. Only by applying a vertical upward force with a special tool can the adjacent floor tiles be separated. This is precisely in line with the usage environment of the floor: when the floor system is in normal use, each floor tile is mainly subjected to vertical downward pressure, and occasionally to a large horizontal thrust. However, the aforementioned vertical downward pressure and horizontal thrust will not cause the floor tiles to separate from each other, and the vertical upward pull that can cause the floor tiles to separate will not occur when the floor system is in normal use.

[0025] 3. When the local floorboards are wood flooring, while making the main body of the wood floorboards, the female buckle body is integrally machined directly on the side of the main body of the floorboards. Then, the elastic arm with a metal or plastic material with a flexible cross tongue is fixedly connected to the female buckle body, so that the floor buckle of this application is also applicable to wood flooring.

[0026] 4. During the vertical assembly of two adjacent base plates, when the elastic horizontal tongue on the male latch contacts the female latch and the elastic horizontal tongue and spring arm are about to be deformed by pressure, the outer groove wall of the vertical tongue slot abuts against the inner surface of the vertical tongue. Thus, when the male latch 1 continues to move downwards, causing the spring arm and elastic horizontal tongue to deform inwards, the horizontal thrust exerted on the male latch is resisted by the vertical tongue. This eliminates the need for the installer to apply a horizontal thrust towards the second base plate to the first base plate, further reducing the installation difficulty of the two base plates.

DETAILED DESCRIPTION

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0045] Unless otherwise defined, technical terms or scientific terms used herein should be understood as having the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms "one" or "a" or the like as used herein in the application patent application specification and claims, do not denote a quantity of one but denote the presence of at least one.

[0046] In the present application specification and claims, "inner", "outer", "inboard", "outboard" are described as follows: in the horizontal direction, close to the center of the floor block is "inner", "inboard", and away from the center of the floor block is "outer", "outboard".

[0047] In the description of the present application specification and claims, the terms "upper", "lower", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or unit referred to must have a particular direction, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.

[0048] Now, the embodiments of the present application will be described with reference to the accompanying drawings.

[0049] Embodiment one:

[0050] As in the conventional floor system, the floor system of the present embodiment also comprises a plurality of floor panels laid horizontally on the ground, each floor panel having a substantially rectangular outer contour and each floor panel having a side edge provided with a floor fastener, and adjacent floor panels are connected to each other by means of the floor fasteners of the side edges.

[0051] Figure 1 Two adjacent floor panels in the floor system are shown, 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 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 lowering the first floor panel a relative to the second floor panel b, the male fastener 1 and the female fastener 2 are configured to be unlocked by vertically raising the first floor panel a relative to the second floor panel b.

[0052] The key improvement of the present embodiment is that the male fastener 1 comprises an upwardly recessed vertical tongue slot 101 and a horizontally outwardly extending elastic horizontal tongue 102. The female fastener 2 comprises an upwardly extending vertical tongue 201 and a horizontally inwardly recessed horizontal tongue slot 202. The vertical tongue 201 is inserted into the vertical tongue slot 101 to lock the first floor panel a and the second floor panel b in the horizontal direction. The elastic horizontal tongue 102 is inserted into the horizontal tongue slot 202 to elastically lock the first floor panel a and the second floor panel b in the vertical direction.

[0053] The so-called "elastic horizontal tongue" does not specifically refer to the ability of the horizontal tongue itself to deform elastically, but the "elasticity" of the horizontal tongue can come from the horizontal tongue itself or from other structures connected to the horizontal tongue and the male fastener body (such as the elastic arm described below 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 removed, the "displacement deformation" will recover. The aforementioned "displacement deformation" can be the displacement of the entire horizontal tongue, or the deformation of the horizontal tongue itself, or the local displacement. In the present embodiment, the following structure is adopted:

[0054] The male fastener 1 further comprises a downwardly extending elastic arm 103 and a deformation slot 104 located inside the elastic arm, and the aforementioned elastic horizontal tongue 102 is integrally formed at the lower end of the elastic arm 103.

[0055] In the embodiment, the elastic horizontal tongue 102 is spaced apart from the vertical tongue slot 101 in the horizontal direction, and the elastic horizontal tongue 102 is located outside the vertical tongue slot 101. Correspondingly, the horizontal tongue slot 202 is spaced apart from the vertical tongue 201 in the horizontal direction, and the horizontal tongue slot 202 is located inside the vertical tongue 201. In some other embodiments of the application, the elastic horizontal tongue 102 can also be arranged inside the vertical tongue slot 101, and correspondingly, the horizontal tongue slot 202 is arranged outside the vertical tongue 201. The elastic horizontal tongue 102 and the vertical tongue slot 101 and the horizontal tongue slot 202 and the vertical tongue 201 are arranged to be spaced apart in the horizontal direction (specifically, the horizontal direction perpendicular to the connecting edge of the two floor blocks), which facilitates the manufacturing and vertical assembly of the male and female buckles, and also facilitates the clamping of a sealing strip between the male and female buckles to prevent water, as will be described in detail in Embodiment 3.

[0056] Referring to Figures 2 to 4 As shown in the figure, in the assembly process, the upper half of the outer side surface of the male buckle 1 on the first floor block a abuts against the upper half of the outer side surface of the female buckle 2 on the second floor block b and moves downward vertically. The elastic horizontal tongue 102 on the male buckle 1 moves inward under the extrusion of the upper half of the outer side surface of the female buckle 2, and the elastic arm 103 is compressed (the elastic horizontal tongue 102 is directly compressed) and deformed inward at the lower end. When the elastic horizontal tongue 102 moves downward to the position of the horizontal tongue slot 202, the elastic horizontal tongue 102 is not compressed, the elastic arm 103 recovers the deformation, the elastic horizontal tongue 102 moves outward and is embedded in the horizontal tongue slot 202, 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 201 of the female buckle 2 is just 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.

[0057] 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 exert an upward pulling force on the first floor block a, the elastic horizontal tongue 102 is directly compressed, the elastic arm 103 is compressed and deformed inward at the lower end, and the elastic horizontal tongue 102 moves inward and is separated from the horizontal tongue slot 202.

[0058] Referring to Figure 5 As shown in the figure, in order to facilitate the vertical locking and vertical separation of the male buckle 1 and the female buckle 2 (i.e., the vertical locking and vertical separation of the first floor block a and the second floor block b), the lower half 102a of the outer side surface of the elastic horizontal tongue 102 is arranged as an outer high and inner low guide slope, and the upper half 102b of the outer side surface of the elastic horizontal tongue 102 is arranged as an outer low and inner high guide slope. During the vertical assembly and vertical separation of the two floor blocks, the vertical extrusion force on the elastic horizontal tongue 102 is converted into a horizontal extrusion force (horizontal component force) under the action of the aforementioned guide slope, so that the elastic arm 103 is more easily deformed.

[0059] Further, the upper half 102a and the lower half 102b of the outer side surface of the elastic cross tongue 102 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 cross tongue 102 is a circular arc surface as a whole.

[0060] In order to better guide the elastic cross tongue 102 to be pulled out of the cross tongue slot 202 (when the first floor block is subjected to a large enough pulling force), the upper side slot wall surface 202a of the cross tongue slot 202 of the female buckle 2 is designed as a guide inclined surface with an outer high and an inner low. Further, the upper side slot wall surface of the cross tongue slot 202 is a circular arc surface.

[0061] In the embodiment, each floor buckle is an integrally formed member and is made of an aluminum alloy profile. The floor buckle can also be made of other materials, such as an integrally formed plastic member.

[0062] Of course, the male buckle 1 or the female buckle 2 can also be designed as a split structure assembled by multiple components.

[0063] 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 adhered and fixed to each other, and the floor buckle is adhered and fixed to the side edge position of the honeycomb aluminum plate 3.

[0064] The aforementioned 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, thereby forming a floor buckle embedding gap 3a 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 aforementioned floor buckle embedding gap 3a. Moreover, the part of the floor buckle embedded in the aforementioned floor buckle embedding gap 3a is adhered and fixed to the upper aluminum plate 301 and the lower aluminum plate 302.

[0065] Referring again to Figure 7As 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, such as Figure 8 .

[0066] Embodiment two:

[0067] Figure 9 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:

[0068] In this embodiment, the elastic arm 103 of the male buckle 1 extends upward instead of downward, and the elastic tongue 102 is integrally formed on the upper end of the elastic arm 103 instead of the lower end.

[0069] Embodiment three:

[0070] Figure 10 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:

[0071] In this embodiment, the elastic arm 103 of the male buckle 1 extends vertically, and both ends of the elastic arm 103 are integrally connected with the body of the male buckle, and the elastic tongue 102 is integrally formed on the middle part of the elastic arm 103.

[0072] It should be noted that the "upper end, lower end, middle part" of the elastic arm in the claims and description 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.

[0073] Embodiment four:

[0074] Figure 11 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:

[0075] In this embodiment, a sealing strip 5 is arranged at the matching position of the male buckle 1 and the female buckle 2.

[0076] The sealing strip 5 is arranged between the horizontal tongue groove 202 and the vertical tongue groove 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.

[0077] Embodiment Five

[0078] Figures 12 to 14 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:

[0079] In this embodiment, the body part of each floor block is entirely 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, etc., and is no longer a composite structure of honeycomb base plate and wood panel. The body part of the male buckle 1 is a wood material integrated with the body of the floor block, that is, the male 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 103 with the elastic horizontal tongue 102 is fixedly connected in the wood male 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 female buckle 2 is integrally manufactured with the body part of the floor block, that is, the female buckle 2 is entirely of wood structure and is integrated with the body structure of the floor block, and the female buckle 2 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.

[0080] Embodiment Six

[0081] Figure 15 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:

[0082] In this embodiment, during the vertical assembly of the male buckle and the female buckle, that is, the vertical assembly of the first floor block a and the second floor block b, when the elastic horizontal tongue 102 of the male buckle 1 contacts the female buckle 2, the outer groove wall surface 101a of the vertical tongue groove 101 and the inner surface 201a of the vertical tongue 201 abut each other. 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 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.

[0083] 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 groove 101 to form vertical guidance.

[0084] The above description is merely exemplary of the application, and is not intended to limit the scope of the application, which is defined by the appended claims.
