The disclosure is directed to the field of flooring, and more in particular, the disclosure relates to a flooring buckle and a corresponding flooring installation structure. There are many kinds of flooring commonly used in the market, including a solid wood flooring, a reinforced laminate wood flooring, a three-layer parquet flooring, a bamboo-wood flooring, an anti-corrosion flooring, a cork flooring, a multi-layer parquet flooring, and so on. Among them, the laminate flooring is formed by cross-laminating multiple layers of boards made of different materials, and is widely popular in the current home furnishing market.
A single-sided flooring only has a decorative layer adhered to one side surface thereof, which has a relatively single decorating effect and can only be used in one side. After a long period of use, the decorative layer on the surface is gradually worn away, patterns are blurred, and the decorative layer may even fall off, so that the aesthetic property is seriously affected. In addition, single veneer layers of most of the floorings have a relatively simple style, and cannot realize spliced combination of a variety of styles. Therefore, a double-sided flooring having decorative layers on both sides has broad market prospects.
The flooring panels of the prior art are usually spliced by mating male edges with female edges, for instance as shown in

An objective of the present disclosure is to provide a flooring buckle and a corresponding flooring installation structure, which can fabricate a double-sided flooring having good locking effects.
In one aspect, the double-sided laminate flooring may be provided female slots only. Such a double-sided laminate flooring having female slots only cannot be spliced directly, and needs connectors for connection. A double-sided spliced flooring may include a notch (i.e, the female slot) on each of two opposite sides of the flooring. A rectangular buckle may be used as a connector. The two ends of the buckle may be respectively inserted into the notches (i.e., the female slots) of adjacent flooring panels. The flooring and the buckle are both of centrosymmetric structures. If the adjacent flooring is turned over and or rotated 180 degrees in the horizontal plane, the floorings can still be spliced together.
In another aspect, the flooring buckle can be adapted and configured to more effectively hold the adjacent flooring panels together when a force is applied to the flooring panels. In particular, the buckle may be adapted and configured to limit any tendency for the adjacent flooring panels to separate under an applied force. Accordingly, the flooring buckle may include a buckle body and four locking pieces respectively arranged on both sides of an upper end and both sides of a lower end of the buckle body, such that the projection of the flooring buckle on end planes of the buckle body is I-shaped, and the flooring buckle is of a centrosymmetric structure. A hole for insertion of a screw or a stake (e.g., nail, pin, dowel pin, rolled pin, rod) may be provided on an end of the buckle body. The diameter of the hole may be slightly smaller than the diameter of the screw or the stake, such that the locking pieces are all slightly deformed at an angle ranging from 1° to 7.5° when the screw or the stake is inserted. It is preferable to arrange the hole at the center of the flooring buckle, such that the locking pieces deform at basically the same angle. A slight offset of the hole from center, such as a left, right, up, down, upper left, lower left, upper right or lower right offset is also acceptable as long as the locking pieces are deformed at a desired angle. More preferably, the locking pieces are deformed at an angle ranging from 2° to 6.5°. If the angle of deformation is too small, the force for the locking pieces abutting against the inner surface of the notches of the flooring is not enough to balance the outward pushing force applied by the flooring buckle to the flooring, such that the adjacent flooring panels may be loosened. If the angle of deformation is too large, the force for the locking pieces abutting against the inner surface of the notches of the flooring is not enough to balance the outward pushing force applied by the flooring buckle to the flooring, such that the flooring may also be loosened. Also, if the angle of deformation is too large, it may lead to flooring deformation, buckling out of the flooring, or cracks in the buckle and/or the slots of the adjacent flooring panel. Therefore, it is preferably that the angle is controlled at an appropriate range. A range of 1° to 7.5° is an acceptable range, and 2° to 6.5° is a more preferable range.
The flooring buckle may be made of metal or engineering plastic. The buckle body and the locking pieces of the flooring buckle may be formed integrally and may be formed monolithically.
Preferably, when the flooring buckle is of metal, the locking pieces of the flooring buckle are welded onto the buckle body.
Preferably, when the flooring buckle is of engineering plastic, the locking pieces of the flooring buckle are adhered to the buckle body with a hot-melt adhesive.
Preferably, the flooring buckle is made of aluminum alloy, magnesium alloy or titanium alloy.
Preferably, the depth of the hole is equal to or slightly greater than the length of the screw.
Preferably, the length of the screw is greater than 5.0 mm, and the diameter of the hole is between 0.8 mm and 3.0 mm.
Preferably, the width of one end of the locking pieces away from the buckle body is equal to the width of one end connected to the buckle body.
Preferably, the width of a distal end of the locking pieces (i.e., the width dimension of the locking pieces at a position away from the buckle body) is slightly greater than the width of the proximal end of the locking pieces (i.e., the width dimension of the locking pieces at a position adjacent to the buckle body).
Preferably, the distal end of the locking pieces (i.e., the ends away from the buckle body) has a semicircle-shaped or semiellipse-shaped cross section, and the effective width dimension at the distal end taking into account the diameter of the semicircle or semiellipse and the locking pieces is slightly greater than the width dimension at the proximal end of the locking pieces (i.e., the width dimension of the locking pieces at a position adjacent to the buckle body).
Preferably, a plurality of flooring buckles are formed integrally as a block of buckles. Preferably, the hole is a through hole that passes through the plurality of flooring buckles of the block of buckles. Preferably, the block of buckles is provided perforations that form preferential tear lines so that individual buckles may be separated from the block of flooring buckles at each tear line. By forming the plurality of flooring buckles integrally as a block of flooring buckles, the cost of fabrication of the buckles can be reduced. A moderate level of force may be applied along the tear lines arranged at joints between the flooring buckles to separate the flooring buckles for ease of use.
A flooring installation structure is also disclosed, including a flooring and the flooring buckle, wherein notches of adjacent flooring panels mating with the flooring buckle are provided at two opposite sides of the flooring, and the flooring is of a centrosymmetric structure.
Preferably, the top surface and the bottom surface of the flooring panel are both covered with a printing layer so as to allow the flooring panel to be flipped over for double sided use.
Preferably, the top surface and the bottom surface of the flooring are further covered with a wear resistant layer above the printing layer. The top surface and the bottom surface of the flooring may be printed with different patterns or in the alternative, the top surface and the bottom surface of the flooring may be printed with the same patterns.
As will become evident from the discussion that follows, the flooring buckle may have a generally I-shaped structure with a hole at the center or a position close to the center. The diameter of the hole may be sized smaller than the diameter of a screw or stake to be inserted in the hole. The flooring buckle may be slightly deformed when the screw or stake is driven into the hole. Insertion of the screw or stake into the hole causes the locking pieces to have a slight displacement outwardly such that the locking pieces abut against the inner surface of the notches of the adjacent flooring panels, which in turn holds the flooring buckle more securely with the flooring thus reducing the tendency for the adjacent flooring panels to become separated.
In the flooring installation structure, the flooring and the flooring buckle are both of centrosymmetric structures, which can readily achieve a double-sided spliced flooring. For flooring exhibition sites (e.g. retail stores, trade shows, merchandising events, demonstrations, expos, etc.), the number of the flooring patterns that can be exhibited or demonstrated can be doubled in the same area. For end users, they can splice patterns according to their own preferences. After the surface layer of the exposed portion of the flooring panel is worn or damaged, the flooring can be turned over for use, thus prolonging the service life of the flooring.
The present invention is further illustrated in the following with reference to the accompanying drawings and embodiments.
To minimize the risk that when a force is applied to the flooring, the adjacent flooring panels will not separate and loosen from the buckle, the flooring buckle may be modified as described below. Making reference to
The buckle body 11 may have a hole 16 on at least one of the first and second ends. The hole 16 may be adapted and configured to receive an expansion body 20. A diameter of the hole 16 may be sized smaller than a diameter of the expansion body 20. A depth of the hole 16 may be equal to or greater than a length of the expansion body 20. A length of the expansion body 20 may be at least 5 mm, and the diameter of the hole may between 0.8 mm and 3.0 mm. The flooring buckle 10 is adapted and configured such that at least one of the four locking members 12,13,14,15 is deformed and at least a portion of the deformed locking member engages a slot of a flooring panel when the locking member is inserted in the slot of the flooring panel and the expansion body 20 is inserted in the hole 16 of the buckle body 11.
The locking members 12,14 on one side of the buckle body 11 may be adapted and configured to move away from each other when the expansion body 20 is inserted in the hole 16 of the buckle body. The locking members 13,15 on the other side of the buckle body 11 may be adapted and configured to move away from each other when the expansion body 20 is inserted in the hole 16 of the buckle body. A distal end of the at least one of the four locking members 12,13,14,15 may move an angle (a) between 1° and 7.5° when the expansion body is inserted in the hole of the buckle body. More preferably, a distal end of the at least one of the four locking members 12,13,14,15 may move an angle (a) between 2° and 6.5° when the expansion body is inserted in the hole of the buckle body.
