1. Field of the Invention The present invention relates to frame materials, and more particularly, to a combination frame material.

2. Description of the Related Art

A known composite frame material in the market comprises a plastic-wood outer frame with an aluminum extrusion inner frame embedded therein, which is applied on window frames, handrails, or constructional decoration for pillars, such that constructional elements of single wood or metal material is substituted thereby.

However, said plastic-wood outer frame and aluminum extrusion inner frame are combined to each other in opposite direction. In other words, the opening of the plastic-wood outer frame faces the opening of the aluminum extrusion inner frame in the combination. As a result, during the embedding process, operator shall carefully and accurately match the openings of these two components, so as to fit the aluminum extrusion inner frame in the opening of the plastic-wood outer frame. Especially, due to the material characteristics of the aluminum extrusion inner frame, the opening tends to expand open, thereby hindering the installation process and lowering the efficiency of the combining operation. Furthermore, due to insufficient structural strength at the place where the plastic-wood outer frame combined with the aluminum extrusion inner frame, concentration of the stamp force when being applied to the floor easily cause structural damage thereupon. Therefore, said composite frame material needs to be improved.

DETAILED DESCRIPTION OF THE INVENTION

The aforementioned and further advantages and features of the present invention will be understood by reference to the description of the preferred embodiment in conjunction with the accompanying drawings where the components are illustrated based on a proportion for explanation but not subject to the actual component proportion.

Referring to FIG. 1 to FIG. 4, the combination frame material 1 provided by the present invention comprises an outer frame 10 and an inner frame 20.

The outer frame 10 is made of plastic-wood material in strip shape. The raw material of the outer frame 10 is an extrusion of a mixture mainly of thermoplastic and natural fiber (such as wood powder, rice hull, wheat straw, and bamboo powder). The outer frame 10 has an outer side and an inner side, while the inner side is provided with a wood-like pattern, and has two parallel combining grooves 11, 12 with a middle pillar 13 therebetween for dividing the two combining grooves 11, 12. The combining grooves 11, 12 are provided with a first inner wall 111, 121 and a second inner wall 112, 122 oppositely disposed against the first inner wall 111, 121, respectively, while the first inner walls 111, 121 and the second inner walls 112, 122 are provided with at least an inclining concave strip 14, respectively. In the preferred embodiment of the present invention, the first inner wall 111, 121 has two concave strips 14, respectively, and the second inner wall 112, 122 has one concave strip 14, respectively.

The combining grooves 11, 12 further have a bottom wall 113, 123, respectively, while two sides of the two bottom walls 113, 123 are provided with a corner recess 15, respectively, which is in a concave-arc shape, thereby preventing the outer frame 10 to deform when exposed to heat. Furthermore, two sides of the outer frame 10 are provided with a connect groove 16, respectively, while a connector 17 (as shown in FIG. 5) is received in the connect groove 16, so as to connect another outer frame 10. The second inner walls 112, 122 of the combining groove 11, 12 are oppositely disposed at the two outer faces of the middle pillar 13, respectively.

The inner frame 20 is made of an aluminum extrusion strip, having two parallel combining parts 21, 22 for being received in the two combining grooves 11, 12. A pillar groove 23 is disposed between the two combining parts 21, 22 for receiving the middle pillar 13. Therein, the combining parts 21, 22 are provided with a first outer wall 211, 221 and an opposite second outer wall 212, 222, respectively. The first outer wall 211, 221 are provided with at least one convex strip 24, respectively, for matching the concave strip 14. In the preferred embodiment of the present invention, each of the first outer walls 211, 221 has two convex strips 24.

Furthermore, the first outer wall 211, 221 and the second outer wall 212, 222 are connected by a combining wall 213, 223, respectively, such that the combining wall 213, 223, the first outer wall 211, 221, and the second outer wall 212, 222 of the inner frame 20 form a U-shaped structure. When the inner frame 20 is combined with the outer frame 10, the combining wall 213, 223 contact the bottom walls 113, 123, respectively, whereby the inner frame 20 and the outer frame 10 are combined with each other in an identical direction. In other words, the openings of the inner frame 20 and the outer frame 10 face the same direction, facilitating the combining process of the inner frame 20 and the outer frame 10.

Also, a slope 25 is disposed at the junctions of the combining wall 213, 223 connected with the first outer wall 211, 221 and with the second outer wall 212, 222, respectively, for correspondingly overlapping the corner recess 15. The second wall 212, 222 of the combining part 21, 22 is oppositely formed at the two inner faces of the pillar groove 23, respectively.

Referring to FIG. 4, during the combination, the inner frame 20 is allowed to be fixed on the floors, walls, or other locations in advance by use of fasteners (not shown in the drawings), with the combining parts 21, 22 thereof facing outward. Next, the outer frame 10, with the combining grooves 11, 12 respectively facing the combining parts 21, 22, is tapped inward to couple the inner frame 20, so that the match of the convex strips 24 and the concave strips 14 prevents the inner frame 20 and the outer frame 10 from departing from each other. Also, due to the openings of the inner frame 20 and the outer frame 10 facing the same direction, the inner frame 20 and the outer frame 10 are able to be combined efficiently, so as to prevent aligning difficulty thereof. In addition, the slope 25 provides the convenience of the outer frame 10 smoothly coupling the inner frame 20, so that the outer frame 10 is allowed to efficiently coupling the inner frame 20 even if the inner frame 20 is in an expanding status. Also, the middle pillar 13 between the combining groove 11 and the combining groove 12 is received in the pillar groove 23, whereby the combining walls 213, 223 contact the bottom wall 113, 123, respectively. As a result, when the outer frame 10 bears an external force, the middle pillar 13 is able to disperse the external force for achieving a better support effort, so that the outer frame 10 is prevented from deform due to force bearing, thus providing a higher structural strength to the combination frame material 1 of the present invention.

Furthermore, even if the two combining parts 21, 22 of the inner frame 20 deform to be narrowed, the two slopes 25 thereof are able to push toward the middle pillar 13, whereby the pillar groove 23 clamps the middle pillar 13 with higher tightness. The concave strips 14 on the two sides of the middle pillar 13 allow the outer frame 10 to be partially coupled and engaged, so as to provide a buffering effect, thereby mitigating the deformation of the outer frame 10 and realize a higher structural strength of the product.

With the foregoing configuration, the inner frame 20 is able to be fixed at a predetermined position in advance. The outer frame 10 is provided with a wood-like pattern to achieve an appearance variety, and at the same time to solve the disadvantages of a real wood material consuming natural resource and of a metal material being aesthetically stiff and heat absorbing easily.

Referring to FIG. 5, with the foregoing configuration, the combination frame material 1 in accordance with the present invention is allowed to be applied on floors.

Referring to FIG. 6, with the foregoing configuration, the combination frame material 1 in accordance with the present invention is allowed to be applied on walls.

Referring to FIG. 7, with the foregoing configuration, two combination frame materials 1 in accordance with the present invention are allowed to be combined back to back by use of the two inner frames 20 thereof, with the two outer frames 10 thereof are combined to the two inner frames 20 afterward, respectively, so as to form a column 2.

With the description above, the combination frame material provided by the present invention is allowed to be applied on scopes of floors, walls, or columns. The outer frame and the inner frame models are possible to be molded for lowering cost of manufacturing. Furthermore, when the outer frame and the inner frame are being combined, the two respective openings face the same direction, such that the combination between the two frames is accelerated, thus facilitating the constructional decoration. Therefore, the combination frame material of the present invention is applicable in various scopes.

Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
