1. Field of the Invention

The present invention relates to a floor and, more particularly, to a composite floor.

2. Description of the Related Art

A conventional composite floor in accordance with the prior art shown in FIG. 9 comprises a plurality of boards 40 juxtaposed to and connected with each other. Each of the boards 40 is fixed on the ground 42 by a plurality of fastening nails 41 which are in turn extended through each of the boards 40 and are nailed into the ground 42. However, it is difficult to nail the fastening nails 41 through each of the boards 40 into the ground 42 so that the boards 40 are connected by hand tools and are not assembled easily and quickly. In addition, a user cannot easily nail the fastening nails 41 through each of the boards 40 into the ground 42 so that the boards 40 have to be mounted by a professional technician, thereby increasing the costs of assembly. Further, the fastening nails 41 are inserted into the ground 42 to break the structure of the ground 42 so that many holes are formed in the ground 42 after removal of the boards 40, thereby decreasing the outer appearance of the ground 42, and thereby increasing the costs of maintenance and mending. The boards 40 are broken after being removed from the ground 42 so that the boards 40 cannot be reused after removal, thereby wasting the material.

Referring to the drawings and initially to FIGS. 1-6, a composite floor in accordance with the preferred embodiment of the present invention comprises a base layer 10, a middle layer 20 mounted on the base layer 10, a surface layer 30 mounted on the middle layer 20, a bonding member 15 located between the base layer 10 and the middle layer 20, and a releasing member 16 releasably mounted on the bonding member 15 and partially covering the base layer 10.

The base layer 10 has a first side 11, a second side 12 located opposite to the first side 11, a third side 13 located between the first side 11 and the second side 12, and a fourth side 14 located between the first side 11 and the second side 12 located opposite to the third side 13. The first side 11 and the second side 12 of the base layer 10 are longer sides and are parallel with each other. The third side 13 and the fourth side 14 of the base layer 10 are shorter sides and are parallel with each other.

The first side 11 of the base layer 10 is provided with a plurality of inserts 111. The inserts 111 of the base layer 10 are equally spaced from each other. Each of the inserts 111 of the base layer 10 has a distal end provided with a first stop portion 112. The first stop portion 112 of each of the inserts 111 is parallel with the first side 11 of the base layer 10. Each of the inserts 111 of the base layer 10 has a first side provided with a first abutting face 113 and has a second side provided with a first tapered face 114. The first abutting face 113 of each of the inserts 111 is perpendicular to the first side 11 of the base layer 10. The first tapered face 114 of each of the inserts 111 and the first side 11 of the base layer 10 have an obtuse angle defined therebetween.

The second side 12 of the base layer 10 is provided with a plurality of slots 121 which correspond to the inserts 111 of the first side 11 respectively. The slots 121 of the base layer 10 are equally spaced from each other. Each of the slots 121 of the base layer 10 has a bottom wall provided with a second stop portion 122 corresponding to the first stop portion 112 of the respective insert 111. The second stop portion 122 of each of the slots 121 is parallel with the second side 12 of the base layer 10. Each of the slots 121 of the base layer 10 has a first side provided with a second abutting face 123 corresponding to the first abutting face 113 of the respective insert 111 and has a second side provided with a second tapered face 124 corresponding to the first tapered face 114 of the respective insert 111. The second abutting face 123 of each of the slots 121 is perpendicular to the second side 12 of the base layer 10. The second tapered face 124 of each of the slots 121 and the second side 12 of the base layer 10 have an obtuse angle defined therebetween.

The third side 13 of the base layer 10 is provided with at least one protrusion 131. The protrusion 131 of the base layer 10 has a distal end provided with a third stop portion 132. The third stop portion 132 of the protrusion 131 is parallel with the third side 13 of the base layer 10. The protrusion 131 of the base layer 10 has two opposite sides each provided with a third tapered face 133. The third tapered face 133 of the protrusion 131 and the third side 13 of the base layer 10 have an obtuse angle defined therebetween.

The fourth side 14 of the base layer 10 is provided with at least one recess 141 which corresponds to the protrusion 131 of the third side 13. The recess 141 of the base layer 10 has a bottom wall provided with a fourth stop portion 142 corresponding to the third stop portion 132 of the protrusion 131. The fourth stop portion 142 of the recess 141 is parallel with the fourth side 14 of the base layer 10. The recess 141 of the base layer 10 has two opposite sides each provided with a fourth tapered face 143 corresponding to the third tapered face 133 of the protrusion 131. The fourth tapered face 143 of the protrusion 131 and the fourth side 14 of the base layer 10 have an obtuse angle defined therebetween.

The fourth side 14 of the base layer 10 has a first corner provided with a lug 144 and a second corner provided with a breach 145 which corresponds to the lug 144. The lug 144 of the base layer 10 is located at a connection of the first side 11 and the fourth side 14 of the base layer 10. The breach 145 of the base layer 10 is located at a connection of the second side 12 and the fourth side 14 of the base layer 10. The recess 141 of the base layer 10 is located between the lug 144 and the breach 145.

The middle layer 20 is bonded onto the bonding member 15 and is sandwiched between the base layer 10 and the surface layer 30. The middle layer 20 has a size smaller than that of the base layer 10. The middle layer 20 covers and protrudes outward from the first side 11 and the fourth side 14 of the base layer 10, while the second side 12 and the third side 13 of the base layer 10 evades and protrudes outward from the middle layer 20.

The surface layer 30 has a size flush with that of the middle layer 20. Preferably, the surface layer 30 is arranged on the middle layer 20 by printing, doping or coating.

The bonding member 15 is bonded onto and distributed on a whole surface of the base layer 10 evenly and completely. The bonding member 15 is located between the base layer 10 and the releasing member 16.

The releasing member 16 surrounds the middle layer 20 and covers the second side 12 and the third side 13 of the base layer 10. The releasing member 16 has a substantially L-shaped profile and has a first side 161 having a shape matching that of the second side 12 of the base layer 10 and a second side 162 having a shape matching that of the third side 13 of the base layer 10. The releasing member 16 is removed from the bonding member 15 to partially expose the bonding member 15 covering the second side 12 and the third side 13 of the base layer 10.

In assembly, referring to FIGS. 7 and 8 with reference to FIGS. 1-6, a plurality of composite floors are to be assembled. When the releasing member 16 of a first composite floor 1 is removed from the bonding member 15 as shown in FIG. 7, the second side 12 and the third side 13 of the base layer 10 are exposed. Then, each of the inserts 111 of the base layer 10 of a second composite floor 1A is pushed toward and inserted into each of the slots 121 of the base layer 10 of the first composite floor 1 as shown in FIG. 8, while the lug 144 of the base layer 10 of the second composite floor 1A is pushed toward and inserted into the breach 145 of the base layer 10 of the first composite floor 1 so that the first composite floor 1 and the second composite floor 1A are combined together. At this time, the middle layer 20 of the second composite floor 1A covers the exposed second side 12 of the base layer 10 of the first composite floor 1. In such a manner, the composite floors 1 and 1A are assembled successively to form a transverse connection.

In addition, the recess 141 of the base layer 10 of a third composite floor 1B is pushed toward and locked onto the protrusion 131 of the base layer 10 of the first composite floor 1 (or the second composite floor 1A) as shown in FIG. 8, so that the first composite floor 1 (or the second composite floor 1A) and the third composite floor 1B are combined together. At this time, the middle layer 20 of the third composite floor 1B covers the exposed third side 13 of the base layer 10 of the first composite floor 1. In such a manner, the composite floors 1 and 1B are assembled successively to form a longitudinal connection.

Accordingly, the composite floors are in turn combined together by an engagement between the inserts 111 and the slots 121, an engagement between the lug 144 and the breach 145 and an engagement between the protrusion 131 and the recess 141 so that the composite floors are assembled easily and quickly without needing aid of any hand tool. In addition, after the releasing member 16 is removed from the second side 12 and the third side 13 of the base layer 10 of one of the composite floors, the second side 12 and the third side 13 of the base layer 10 of one of the composite floors are covered and positioned by the middle layer 20 of another one of the composite floors so that the composite floors are combined solidly and stably. Further, the composite floors are directly placed on the ground and are combined together by an insertion connection so that the composite floors will not break the structure of the ground so as to maintain the outer appearance of the ground after removal of the composite floors and to save the costs of maintenance and mending. Further, the composite floors can be reused after removal, thereby enhancing the utility of the composite floors.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
