DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(11) Referring from FIG. 1 to FIG. 7, according to the first embodiment of the present invention, a sliding rail structure for drawer of layered frame is mainly designed for being used to satisfying a requirement of allowing a bracket drawer (20) to be disposed in a layered frame (10), and a sliding rail plate (30) is buckled between horizontal rod (11) arranged at two sides of the layered frame (10) so as to assemble a sliding rail for a drawer, the sliding rail plate (30) is formed through a single metal piece being punched for formation, so that a main body thereof is formed as a U-like slot rack (31), locations defined at a front end and a rear end of the slot rack (31) are respectively punched for forming a vertical stop plate (32) which is served as a pushing and pulling limitation for the bracket drawer (20), two predetermined locations at a front end and a rear end of a top edge defined at a sealed side of the slot rack (31) are punched for forming a pair of buckle hooks (33, 34), and distances between the pair of the buckle hooks (33, 34) and a front end par and a rear end part of the sliding rail plate (30) are kept in a different status, so that when an installation of the bracket drawer (20) of the layered frame (10) being arranged in a coupled or multiplied format is required, the two sliding rail plates (30, 30) can be buckled on the same horizontal rod (11) from two sides and kept in an oppositely arranged status, and the buckle hooks (33, 34) thereof are able to be staggeringly disposed without being interfered with each other; moreover, buckle slots (35) of each of the buckle hooks (33, 34) can be designed in various specifications and status with respect to the horizontal rod (11), thus a slot wall of each of the buckle slots (35) is formed in a non-arched polygonal status, thereby achieving a multiple-contact-point positioning effect while being buckled, meanwhile a base part of the main body of each of the buckle hooks (33, 34) being connected to the sliding rail plate (30) is formed with a planar connecting surface (331, 341), thereby providing a reinforcing effect, so that when the sliding rail plate (30) carries the weights of the bracket drawer (20) and stored objects therein, interfacing portions of the planar connecting surfaces (331, 341) and the buckle hooks (33, 34) able to be abutted against the horizontal rod (11), thereby obtaining a better abutting strength and enhancing the stability defined while the sliding rail plate (30) being buckled, and situations of loosening or falling can be prevented, so that the operation of pulling or pushing the bracket drawer (20) can be smoothly and stably performed.
(12) Please refer from FIG. 8 to FIG. 10, according to the first embodiment of the sliding rail structure for drawer of layered frame provided by the present invention, a round horizontal rod is adopted for illustrations, when a round pipe (as shown in FIG. 8 and FIG. 9) or a rectangular pipe (as show in FIG. 10) is adopted as the horizontal rod (11) of the layered frame (10), when the sliding rail plate (30) of the present invention is manufactured, besides the single metal piece is punched for forming the U-shaped slot rack (31) and the stop plates (32) at the front end and the rear end, the buckle slots (35) of the buckle hooks (33, 34) at the two predetermined locations at the front end and the rear end of the top edge defined at the sealed side can be formed in different specifications and statuses, in other words for matching with the round-pipe horizontal rod (11), the specifications of the buckle slots (35) of the buckle hooks (33, 34) of the sliding rail plate (30) are required to be enlarged, the slot wall thereof is formed in the non-arched polygonal status, thereby achieving a stable hooking and hanging effect while being buckled on the round-pipe horizontal rod (11), as shown in FIG. 8 and FIG. 9; when the rectangular-pipe horizontal rod (11) is adopted, the buckle slots (35) of the buckle hooks (33, 34) of the sliding rail plate (30) are designed to be in a rectangular status and the specifications thereof are also enlarged, so that the sliding rail plate (30) can be stably buckled on the rectangular-pipe horizontal rod (11), as shown in FIG. 10; as such, when the sliding rail plate (30) of the present invention is applied in an industrial application, as long as the horizontal rod (11) is disposed at two sides of the layered frame (10), the sliding rail plate (30) with a matched status can be buckled and hanged on the horizontal rod (11) with respect to the different statuses of round-rod, round-pipe or rectangular-pipe, thereby forming the sliding rail for drawer; accordingly, the layer frame (10) is able to work with the bracket drawer (20) for allowing objected to be stored or displayed.
(13) Based on what has been disclosed above, in the sliding rail structure for drawer of layered frame provided by the present invention, the single metal piece is punched for forming the sliding rail plate, so that the whole production cost can be lowered, and the structural strength can also be increased, meanwhile, with the arrangement of the buckle hooks, a smooth operation without being interfered can be provided when the buckle hooks of the sliding rail of the drawer of the layered frame is arranged in the coupled format; and with the design of different specifications and statuses of the buckle hooks of the sliding rail plate, the present invention can be applied in various types of layered frame. Accordingly, the present invention is novel and more practical in use comparing to prior art.
(14) Based on what has been disclosed above, with the improved design of the sliding rail structure for drawer of layered frame provided by the present invention, an advantages of being more practical in use is achieved through the layered frame working with the bracket drawer, so that the whole production cost can be effectively lowered, meanwhile the operation can be more practical, and capable of working with different types of layered frame by the altered designs, thus disadvantages existed in the conventional structure can be effectively solved. Accordingly, the present invention is novel and more practical in use comparing to prior art.
(15) Many modifications and other embodiments of the inventions set forth herein will come to mind to one skilled in the art to which these inventions pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings.
