[Technical field to which the invention belongs]

 The present invention relates to a suitcase, particularly to an improvement of its bottom plate, in which a bottom plate having the same size as the bottom of the case is formed, and a wheel pedestal is already attached to each corner, so that four wheels can be easily placed in the same horizontal plane. It can be installed at any position, greatly reducing the occurrence of defective products due to the wheel position at the time of installation, further reducing production costs. In addition, since the bottom plate directly covers the bottom of the case, the weight on the wheel can be dispersed, and the case can be used safely.

[Prior art]

 With the evolution of commerce and industry, the number of outings, leisure trips, and business trips is increasing, but suitcases with wheels at the bottom are easy to carry, so the number of users is very large. The design of a typical suitcase is to put things inside the empty space of the central framework, and there are two or four wheels at the bottom, making it easy to pull and push the suitcase, making it portable. It is convenient. As shown in FIGS. 4 and 5, the structure of the conventional general bottom plate wheel is such that the mechanism of the wheel 31 at the bottom of the suitcase body 30 is an independent nailing design, and nails directly on the bottom plate 32. Regardless of whether the case is divided as shown in Fig. 4, the position of the case 30 corner must be covered and nailed one by one. This nailing method first imposes inconvenience on the trader. When installing the wheels one by one, first make sure that the front and rear positions and height of the nails are horizontal, and the height of the four wheels 31 must match and be level with the ground. As shown in FIG. 5, if even a small difference does not occur, a gap A having a height is formed, and a bias is generated when the case is placed. Therefore, it is necessary to correct whether or not the wheels are level on the ground and whether the wheels are stable when the case 30 is placed. Otherwise, it will greatly affect the stability of the case. For this reason, great care must be taken when assembling, and it is difficult to determine the position of nails, especially at the corners, because the corners are rounded. As a result, the accuracy of mounting is reduced, and defective products are likely to occur. Not only does the cost of molding increase, but it also wastes time for modifications, greatly reduces the efficiency of installation, and increases its cost. Therefore, it is necessary to overcome these drawbacks in mounting and use, and to further develop and develop them one step further.

[Problems to be solved by the invention]

 In the present invention, in order to solve the problem that the wheel part attached to the bottom of the conventional suitcase requires the actual assembling and the various manufacturing costs and construction time raised above, the suitcase was designed with a single-piece bottom plate. Using the fixed wheel pedestal, it is easy to determine the position and levelness of construction, effectively overcoming the disadvantages of conventional wheel mounting, and increasing the structural strength of the case. is there. The main purpose of the present invention is to design the bottom plate integrally molded.The case body and the bottom plate can be easily fixed with nails, and the nailing of the wheels is also convenient. The purpose can be achieved, and the entire bottom of the case body is further strengthened by the integrally formed bottom plate set, so that the load capacity of the suitcase is more secure.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the suitcase of the present invention is a bottom plate that is designed to improve the wheel portion at the bottom of a general suitcase in consideration of convenience and accuracy. Both sides of the pedestal are drawn with an arc to cover the entire case with a molded bottom plate, and each corner of the bottom plate has a wheel pedestal for attaching wheels in advance, and each wheel should be easily aligned horizontally with the ground. The wheels are easy to wear, and can be leveled when the case is placed. In addition, the middle part of the end of the pull bar handle attached to one side of the case body of the bottom plate is also provided with a support bar base in advance, so it can be inserted correctly and assembled, and the suitcase assembly structure is simple. It is also characterized in that it can be used safely.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the suitcase of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 to 3, the design of the case body 10 is similar to the conventional one, but a plastic bottom plate 20 is attached to the wheel 11 to be attached to the bottom of the case body 10. The shape almost covers the bottom of the case body 10, and each corner is provided with a flat wheel pedestal 21. The wheels 11 are directly mounted on the flat surface of the pedestal, which is convenient, and the four corners coincide. The height of each mounted wheel is the same, and it is stable when placed. Further, since the bottom plate 20 covers the bottom of the case body 10, the bottom is strengthened and the contents of the case are safely wrapped. Also, in the suitcase of the present invention, since the bottom plate 20 of the case body 10 is integrally molded, the flat surface on which the wheels 11 are mounted is the same horizontal plane. The heights along the ground coincide. Therefore, this design can reduce the time required for repairing the mounted wheel 11, and can be more easily mounted horizontally, requiring less assembling techniques, and requiring a higher reject rate, a higher technical level, and a longer repair time. Significantly lower costs. When designing and assembling a particularly large case body 10 by reducing the manufacturing cost, the bottom plate 20 of the present invention is used, and the bottom plate surface is reinforced with a convex line 22 and another wheel 11 is provided at the center of the plate surface. Attach the auxiliary wheel 11 at the center of the large-area plate surface, create a support at the center, and further strengthen the bottom. In particular, the inner frame of the case main body 10 is formed by bending, and the inner frame is flush with the bottom plate surface of the case. Therefore, reinforcement design with wheels in the center is practical and safe.

[0006] Since the bottom plate 20 of the suitcase of the present invention employs integral molding, it is necessary to have a pull bar handle. When the bottom plate 20 is formed, a support bar of the pull bar handle is provided on one side of the plate surface. If the pedestal 23 is formed, that is, the support bar pedestal 23 is molded together, the assembling of the drawbar handle can be correctly inserted directly into the support bar pedestal 23 on one side of the bottom plate 20 so that the nailing position can be easily determined. Since the drawbar is easily assembled, there is no need to make a separate drawbar pedestal. If you see the conventional drawbar fixing pedestal made separately, you will hit a nail on the bottom of the case. For this reason, the bottom surface of the case body 30 is not flat, and there is no clue to the nailing position, so that the nailing position is often incorrect and the quality of the case body 30 is impaired. It is the improved design of the present invention that has improved the disadvantages of assembly that could not be solved until now.

[0007]

[Effect of the invention]

 As explained above, since the suitcase of the present invention is a single-piece bottom plate, it can be easily attached, and the flat surface is attached to the plate surface and the wheels are fastened. In addition, the strength of the bottom of the case body can be easily increased. In addition, the simple mounting of the center wheel and the support bar pedestal has the characteristic that the suitcase is new and of practical value. This is effective for practical and easy assembly.
