Description

A FRAME PRODUCTION METHOD

TECHNICAL FIELD

The present invention relates to a frame production method in a manner encircling the item which is desired to be protected against impact.

PRIOR ART

There are three methods, which have become sector standard, in production of casing for industrial computers. These methods are as follows;

• Mold production method;

By means of the mold production method, injection metals (particularly aluminum) and injection plastic casings are used.

1. Metal casing type: Integrated casings with two parts are used such that there is touch-panel chamber telescopically engaged with injection molds and there is electronic part chamber placed under the touch-panel chamber. Casings are produced in the form of a rectangular prism and the external surface and connection points are processed according to usage areas and casings are formed as desired and are assembled by means of connection elements. The casings are formed by thick frames because of compliancy to mold production, and a serious weight problem occurs. Because of the high amount of metal usage, product unit costs are high. Another problem is that the casing must be processed with high cost and high discard ratio after production with injection in order to form the casing finish as desired. As a fourth problem, a separate injection mold is needed for each type which has different dimensions and unit production cost increases due to mold costs.

2. Plastic casing type: Here, the same design is produced by means of injection method by using plastic material instead of metal. The biggest problem, which occurs in plastic casings, is that the resistance of plastic casings is lower when compared with metal casings. Since separate molds are needed for each type as in metal casings, increase occurs in unit production costs. Due to delimitations in the mold production method and due to resistance problems, the casings cannot be produced with the desired thinness to achieve the required integrity, and high thickness leads to problems in field use .

• Bending production method;

The design, which is most widely used in the sector, is casing production by means of the cutting and bending of metal plates. In the method of production by means of bending, the following steps are provided: bending the touch-panel chamber panel frame for 2 times at 90 degrees, bending the lower chamber once at 90 degrees, hammering the panel supports to the panel chamber, engaging panel holder tabs to supports and assembling the tabs to the support items. Since production method comprises of pluralities of steps, the production process time extends and unit production cost increases. The panels, which form the design chambers, consist of tab parts, support parts, fixation parts and the multi-pieced design decreases stability during the operational lifetime. During the production, deformations can occur in the parts due to hammering of parts, multiple bending and assembly, and the risk of re-processing and discard increases during the production process, and cost loss can occur. Hammering of the panel supports, which will carry the holder tabs, to the front frame can lead to losing of sealing at the front frame. The thickness of the used metal panels cannot be reduced to the desired thinness due to delimitations in the production method (molded bending and support hammering/processing of the support holes). The usage of thin metal cannot be realized because of production difficulties and since the thin metals cannot provide the desired rigidity. The screen panels fixed to the frame must be at the same level as the front surface of the frame, and if the plate thickness is high, thin screen panel cannot be used, and panels with alternative thicknesses cannot be used for a single frame, and cost increase occurs.

• Welded production method;

The problems, faced in bending method, also occur here in a similar manner and longer production processes and higher costs occur due to the high cost of welding processes and surface damages and deformations which occur during welding.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable. In Figure 1 , a representative perspective view of the subject matter frame (10) is given. Accordingly, the frame (10) is configured to encircle the item (60) which is desired to be protected against impact and to protect said item (60) against environmental conditions. In possible embodiments of the present invention, the item (60) which is desired to be protected against impact can be a computer display panel, touch screen, television, solar panel, advertisement panel, electrical panel, glass border, picture border, etc.

With reference to Figure 2, the subject matter frame (10) is produced from at least one plate

(20). As said plate (20) material, a bendable material is preferred. At least one inner cutout part (21) is removed from the plate (20). As said inner cutout part (21) is removed from the plate (20), an opening is provided for the placement of the item (60) desired to be protected in the frame (10). The parts which remain at the sides of the inner cutout part (21) are defined as one each plate parts (30). The side of each plate part (30) which faces the inner cutout part (21) is at least one inner edge (34) and the opposite side thereof is at least one outer edge (35). The plate part (30) is bent through a predetermined bending line (40) between said inner edge (34) and said outer edge (35).

In a possible embodiment of the present invention, during removal of the inner cutout part

(21), at least one each corner cutout part (22) is also removed from the corners of the plate (20). Thus, a structure is formed where the plate parts (30) are integrated to each other through the end parts thereof.

In Figure 3, the representative top view and the cross-sectional view of the subject matter frame (10) after bending and crushing are given. Accordingly, the plate part (30) is bent along at least one first bending line (40a). At least one first part (30a) is formed between the first bending line (40a) and the outer edge (35) of the plate part (30), and at least one second part (30b) is formed between the inner edge (34) and the first bending line (40a). Bending process is applied such that said first part (30a) is rested onto the second part (30b). After bending, bending gap (32) is formed between the first part (30a) and the second part (30b). In order to reduce said bending gap (32), crushing process is applied in a manner pressing the first part (30a) and the second part (30b) towards each other. In said crushing process, the first part (30a) is pressed to the second part (30b) under high force and is brought extra closer. Thanks to this, besides reducing the bending gap (32), a double-layered structure is formed. Thanks to said double-layered structure, a greater resistance is obtained from using sheet with thinner wall thickness than normally required. The distance between the first bending line (40a) and the second bending line (40b) is longer than the distance between the inner edge (34) and the first bending line (40a). Depending on this distance difference, at least one item support part (33) is formed on the first part (30a). Said item support part (33) provides the item (60), desired to be protected, to be rested to the first part (30a) and to be fixed in the frame (10). After the crushing step, the first part (30a) is bent along at least one predetermined second bending line (40b). At least one third part (30c) is formed between the outer edge (35) and the second bending line (40b). Said third part (30c) is bent essentially at a predetermined direction and angle with respect to the first part (30a). In a production method which is the alternative of the described embodiment, before bending through the first bending line (40a), bending is realized through the second bending line (40b). Afterwards, bending is realized through the first bending line (40a) and crushing is applied to the first part (30a) and to the second part (30b).

In Figure 4, the representative cross-sectional views of the production method of an alternative embodiment of the subject matter frame (10) are given. Accordingly, at least one support part (23) is placed in between during bending of the first part (30a) and the second part (30b). Said support part (23) provides the frame (10) to have equal thickness to the item (60), based on the thickness of the item (60). Besides, the support part (23) also increases the resistance of the frame (10) against environmental conditions. In this embodiment, after the first part (30a) and the second part (30b) are bent and after crushing is applied, the third part (30c) is bent in a manner resting to the first part (30a). After bending, in order to reduce the bending gap (32) which is to be formed between the first part (30a) and the third part (30c), crushing is applied to the two parts towards each other. After crushing, the third part (30c) is bent preferably at a predetermined direction along a third bending line (40c). After this bending, at least one fourth part (30d) is formed between the outer edge (35) and the third bending line (40c). Said fourth part (30d) is bent at a predetermined direction along at least one fourth bending line (40d). At least one fifth part (30e) is formed between the outer edge (35) and the fourth bending line (40d). The semi-closed structure formed by the third part (30c), the fourth part (30d) and the fifth part (30e) is at least one chamber (50). Said chamber (50) provides the parts of the item (60), which is desired to be protected, to be covered and provides isolation thereof from the environmental conditions. Since sheet having thinner wall thickness is used in the frame (10), a wider volume is formed in the chamber (50). In another possible embodiment of the present invention, the fifth part (30e) is bent in the opposite direction, a chamber (50) form, which is similar to a bracket, is obtained at one side of the fourth part (30d), and the fifth part (30e) which can be used as a sealing item. In a possible embodiment of the present invention, the frame (10) can be formed by two frames (10), which are the symmetric of each other and which are side by side. Thanks to this, extra protection can be provided at the sides of the item (60). By means of all these embodiments, the long and complex applications like outer surface hammering, processing, coating, etc. are eliminated. As said applications are eliminated, capability of operating with high tolerance values is obtained. As no mold is used for the processing of the sheet, the increase in the production costs is prevented, and alternative casing types can be produced by using a single type of metal plate (20). Moreover, the stability is increased thanks to the single-piece structure.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
