BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an reinforcing and shape-fixing structure for a sheet material product, in which a plastic frame is adopted as a shape-fixing component for the sheet material product, and an end edge of the sheet material is formed with through holes, so after the plastic frame is sleeved with the end edge of the product, a thermal pressing operation is processed for allowing the material of which the plastic frame is made to pass the through holes thereby being integrated with each other, so a firmly combining effect is obtained.
2. Description of Related Art
A stationary or other items used in an office such as a storage box, file folder, pen holder or trash bin is fabricated through plastic injection molding or adopting a rigid material such as a metal sheet or grid net, thereby being able to maintain the structural configuration, the mentioned art can provide a better structural strength and effectively maintain its function, but the material cost is relatively higher; for the severe market competition which has almost led to an era with very little profit zone, manufacturers are all devoting themselves for competing and gaining more market shares.
In order to lower the material cost for this certain type of product, the manufacturers try to find or develop new materials, wherein some manufacturers attempt to use the light and thin sheet material which has a lower price to replace the structure formed through plastic injection molding or punching or folding the metal sheet or grid net so as to make the whole structure thinner, and also make the whole weight lighter, thereby effectively reducing the cost for material, transportation and storage; however, fabricating the product by adopting the light and thin sheet material would cause the whole structure not having enough strength, and the structural configuration is therefore hard to be fixed. In view of the mentioned disadvantages, the present invention provides a reinforcing and shape-fixing structure for a sheet material product.
SUMMARY OF THE INVENTION
In order to allow a light and thin sheet material to be fabricated to a product such as a storage box, file bolder or pen holder, the aim of the present invention is to maintain the structural configuration after the product made of the light and thin sheet material being formed, thereby increasing the whole structural strength and being more applicable in industries.
In view of the disadvantage that the thickness of a product made of a light and thin sheet material being overly thin and causing the structural configuration being hard to maintained when subject to an external force, the present invention adopts a plastic frame mated with the end edge of a product, by being sleeved with the plastic frame, the structural strength of the product can be reinforced and a shape-fixing effect is also provided, and in order to firmly combine the plastic frame and the sheet material made of different material, through holes are formed close to the end edge of the sheet material thereby allowing the melted material of which the plastic frame is made to pass so as to be integrated with each other.
The reinforcing and shape-fixing structure for a sheet material product provided by the present invention adopts a plastic frame to be sleeved with an end edge of a sheet material product thereby being able to stably maintain the configuration of the product, so the light and thin sheet material can be used for replacing the conventional material for being applied in industries, and saving the cost of material, storage and transportation; moreover, with the colors provided to the plastic frame, the whole outlook can be varied by changing the combination of colors, thereby the quality and outlook of the whole product being enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring from FIG. 1 to FIG. 5, wherein FIG. 1 is an exploded view showing the structure according to a first preferred embodiment of the present invention; FIG. 2 is a schematic view showing the structure according to the first preferred embodiment of the present invention; FIG. 3 is a schematic view illustrating the structural relation according to the first preferred embodiment of the present invention; FIG. 4 is an exploded view showing the structure according to a second preferred embodiment of the present invention; and FIG. 5 is a schematic view showing the structure according to the second preferred embodiment of the present invention. As shown in figures, the structural design mainly adopts a light and thin sheet material (e.g. a paper sheet, PP sheet, plastic sheet, metal sheet or net sheet) which is punched or folded or assembled to a sheet material product (10) having a preset configuration (e.g. a product for storing or accommodating such as a storage box, file folder, pen holder, trash bin). The sheet material product (10) is formed with at least an end port (11) allowing objects to be entered from, the end port (11) can be formed in a sealed contour status or semi-sealed contour status so as to formed an opened end edge (12), and a proper location of a lateral sheet of the sheet material product (10) close to the end edge (12) is formed with a preset amount of through holes (13) with respect to the contour of the end port (11), and a plastic frame (20) having the same configuration relative to the end port (11) of the sheet material product (10) is formed, the bottom end of the plastic frame (20) is formed with a mount slot (21) having a dimension corresponding to the configuration and thickness of the end port (11) of the sheet material product (10), and the depth of the mount slot (21) is at least greater than the distance defined from the end edge (12) of the sheet material product (10) to the bottom edge of the through hole (13), so when the plastic frame (20) is sleeved with the end port (11) of the sheet material product (10), two lateral sheets (22) of the plastic frame (20) are enabled to fully cover and shield the through holes (13), and when the two lateral sheets (22) of the plastic frame (20) is processed with a thermal pressing operation through high frequency or ultrasonic, the material of which the two lateral sheets (22) are made can be melted for passing the through holes (13) thereby being integrated with each other, so the plastic frame (20) is enabled to be firmly sleeved with the end edge (12) of the end port (11) of the sheet material product (10), so the plastic frame (20) provides a shape-fixing and structure reinforcing effect to the configuration of the sheet material product (10), and with the colors provided to the plastic frame (20), the whole outlook can be varied by changing the combination of colors, thereby the quality and outlook of the whole product being enhanced.
