GB 2312687 - In addition,
US Patent No. 7,546,717 discloses a timber covering for exteriors and interiors, comprising a plurality of strips fixed by means of fastening clips to a supporting framework. The fastening clip is located between two adjacent strips and provided with two opposite wings introduced in the grooves of two adjacent strips so as to reduce the lateral play of the strips. However, since the wings of the fastening clip are arranged in opposite direction, a large gap will be left between the strips. In order to prevent the fastening clip from being seen from the gap, and stop small objects, such as twigs, flowers, leaves, piece of paper, etc., from passing through the gap, the strips have an arrangement of mating projections and recesses to leave various gaps. In this way, the timber covering has the defects of complicated structure and high manufacturing cost. - It is one objective of the present invention to provide a fastener for a combination floor, which has high elastic deformation ability to absorb thermal expansion of the combination floor panels.
- To attain the above-mentioned objective, the fastener provided by the present invention comprises a base portion, a first arm portion, at least one second arm portion, a first tongue portion, and at least one second tongue. The first arm portion and the second arm portion both extend upwards from a side of the base portion. The first tongue portion extends horizontally from a top end of the first arm potion along a first direction away from the base potion for stopping against a female panel, and the second tongue potion extends horizontally from a top end of the second arm portion along a second direction opposite to the first direction for stopping against a male panel. By means of the aforesaid design, the fastener of the present invention can effectively absorb thermal expansions of the male panel and the female panel due to temperature variation.
- In a preferred embodiment, the first tongue portion and the second tongue portion are coplanar, and the first tongue portion has an area greater than that of the second tongue portion; and further, a curved chamfer is formed between the base portion and the first arm portion, and between the first arm portion and the first tongue portion, and between the base portion and the second arm portion, and between the second arm portion and the second tongue portion for facilitating elastic deformation of the fastener of the present invention.
- It is another objective of the present invention to provide a floor, which has a simple structure and is low cost in manufacturing.
- To achieve the above-mentioned objective, the combination floor provided by the present invention comprises a male panel having a lower shoulder portion, a female panel having an upper shoulder portion facing the lower shoulder portion of the male panel and a recess adjoined with the upper shoulder portion, and the above-mentioned fastener. The base portion of the fastener is abutted against a bottom of the male panel. The first tongue portion is inserted into the recess of the female panel. The second tongue potion defines a notch with the second arm portion for engagement of the lower shoulder portion of the male panel. Accordingly, the combination floor of the present invention can be assembled easily to leave a minimum gap between the male panel and the female panel, thereby attaining the purpose of lowering the cost without complicated design.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

FIG. 4 is a perspective view of a combination floor using the fastener according to the preferred embodiment of the prevent invention; and -
FIG. 5 is a partially sectional view ofFIG. 4 . - As shown in
FIG. 1 , afastener 10 in accordance with a preferred embodiment of the present invention comprises abase portion 20, afirst arm portion 22, twosecond arm portions 24, afirst tongue portion 26, and twosecond tongue portions 28. - The
base portion 22 has a circular throughhole 202 at a middle thereof. - Referring to
FIGS. 2 and 3 , thefirst arm portion 22 integrally extends upwards from one side of thebase portion 20, and defines a curved chamfer with thebase portion 20. - The
second arm portions 24 integrally extend upwards from one side of thebase portion 20 in such a manner that thesecond arm portions 24 are located on the same side as thefirst arm portion 22 and located at places corresponding to two opposite sides of thefirst arm portion 22 respectively. A curved chamfer is defined between each of thesecond arm portions 24 and thebase portion 20. - The
first tongue portion 26 extends integrally and horizontally from a top end of thefirst arm portion 22 toward a direction away from the other side of thebase portion 20. - The
second tongue portions 28 each extend integrally and horizontally from a top end of one of thesecond arm portions 24 toward a direction approaching the other side of thebase portion 20, and each define a curved chamfer with one of thesecond arm portions 24. Thefirst tongue portion 26 and thesecond tongue portions 28 are coplanar, and thefirst tongue portion 26 has an area greater than that of thesecond tongue portion 28. - The structure of the
fastener 10 is described as above, and the assembly process of acombination floor 30 using thefastener 10 of the present invention is outlined hereinafter. - Referring to
FIGS. 4-5 , thecombination floor 30 comprises a plurality ofbeams 32, a plurality ofmale panels 34, and a plurality offemale panels 36. - The
male panel 34 is placed on thebeams 32 and has alower shoulder portion 342 protruding from a bottom edge of one side thereof, and aconcavity 344 recessed from a bottom surface thereof. - The
female panel 36 is placed on thebeams 32 in such a manner that thefemale panel 36 is spaced from themale panel 34, and has anupper shoulder portion 362 protruding from a top edge of one side thereof and facing thelower shoulder portion 342 of themale panel 34 so as to define agap 38 with themale panel 34, and arecess 364 adjoined with theupper shoulder portion 362. - When the
male panel 34 and thefemale panel 36 are combined with each other by using thefastener 10, thefirst tongue portion 26 of thefastener 10 is inserted into therecess 364 of thefemale panel 36 for stopping against thefemale panel 36, and then anail 40 is fastened to thebeam 32 through the thoughhole 202 of thebase portion 20 for securing thefastener 10. Thereafter, thelower shoulder portion 342 of themale panel 34 is engaged with anotch 29 defined by thesecond arm portion 24 and thesecond tongue portion 28 such that the top surface of thebase portion 20 and the bottom surface of themale panel 34 are abutted against each other, and meanwhile a head portion of thenail 40 is received in theconcavity 344 of themale panel 34 without exposure, thereby completing the assembly of thecombination floor 30. - In conclusion, since the
first arm portion 22 and thesecond arm portion 24 are located on the same side of thebase portion 20, thegap 38 defined between themale panel 34 and thefemale panel 36 can be reduced to a minimum after the assembly of thecombination floor 30, thereby preventing possible drop of small objects, such as twigs, flowers, leaves, pieces of paper, and etc., through the gap into the combination floor. Furthermore, thefastener 10 won't be seen from thegap 38 by means of the arrangement of theupper shoulder portion 362 of thefemale panel 36 and thelower shoulder portion 342 of themale panel 34, so that thecombination floor 30 has a smooth appearance and simplified structure to attaining the purpose of reducing manufacturing cost. - On the other hand, when the
male panel 34 and thefemale panel 36 are expanded due to temperature variations, thefemale panel 36 will apply a force to thefirst tongue portion 26 of thefastener 10 to cause the deformation of thefirst arm portion 22 so as to absorb the thermal expansion of the female panel, and meanwhile thelower shoulder portion 342 of themale panel 34 will apply a force to cause the deformation of thesecond arm portion 24 of thefastener 10. Under this circumstance, because a space is left between thefemale panel 36 and thefirst arm portion 22 of thefastener 10, thefirst arm portion 22 of thefastener 10 can exhibit a high elastic deformation capacity as the force is applied thereon; moreover, thefastener 10 has the curved chamfer between thebase portion 20 and thefirst arm portion 22, and between thefirst arm portion 22 and thefirst tongue portion 26, and between thebase portion 20 and thesecond arm portion 24, and between thesecond arm portion 24 and thesecond tongue portion 28 for facilitating elastic deformation of thefastener 10. As a result, thefastener 10 of the present invention can effectively absorb thermal expansions of themale panel 34 and thefemale panel 36. - Besides, since the
first tongue portion 26 is located between thesecond tongue portions 28, and has an area greater than that of each of thesecond tongue portions 28, the expansion force generated by themale panel 34 and the expansion force generated by thefemale panel 36 can be balanced with respect to each other for preventing the rotation of thefastener 10. - The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
