Slide linking apparatus

Abstract

A slide linking apparatus includes a fixing base of a chassis, a positioning member at the fixing base, an aslant blocking plate on the fixing base, and first and second rails engaged with each other and embedded into the fixing base. The first rail includes a swing member having an extending portion and embedded into a slide groove. The second rail includes a link member pressing the swing member, such that when the second rail slides outward, the link member presses the extending portion of the swing member and drives the first rail to move until the swing member is pressed downward by the aslant blocking plate and separated from the link member and the first rail stops. When the second rail slides inward, the process is reverse. Since the first and second rails are moved synchronously, the pressure exerted on the second rail will be reduced to prevent deformations.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a slide linking apparatus, and more particularly to a slide linking apparatus having a link member and a swing member that work together to slide a first rail and a second rail outward and share the weight exerted on the second rail which is fixed to an object, so as to prevent the rails from being deformed.

[0003] 2. Description of the Related Art

[0004] In general, a traditional slide structure for chassis or drawers usually installs rollers on both sides of the chassis and rails of an object or a drawer, so that the slides are engaged with the rollers, and the rear end of the rails has an arc guide rail disposed at a position lower than the rails. Although the rollers are rolled, the base of the object or drawer is moved accordingly and entered into the guide rail along the rail. By the slope naturally formed between the guide rail and the rail and the weight of the object or drawer, the drawer can be fixed at a desired position. However, the weight of the object, the drawer and their contents produces a certain pressure onto the guide rail or deforms the guide rail, such that the slope between the rail and the guide rail is changed from a smooth slope to a bumpy slope. As a result, the object or drawer will move in an unsmooth manner or even get stuck during the process when the guide rail enters into the rail. Since the position of the guide rail is lower than the rail, the weight of the object or the drawer with its contents makes the pulling process very tiresome and the application very inconvenient, when the object or drawer is moved from the guide rail towards the rail.

[0005] Further, the structure of another slide comes with a sliding rail, and the sliding rail has a first rail and a second rail, wherein the second rail is embedded into the first rail, and the ends of the first and second rails are expanded outward. When this apparatus is used, the second rail will slide outwards as the object moves, until the end of the second rail is latched onto the first rail, and then the first rail will start sliding outward. If a chassis is pulled outward or maintained, the first rail and the second rail do not move synchronously, but the weight of the chassis is concentrated on the first rail, and thus the second rail may be failed or stuck due to its deformation, and causes lots of problems to its applications.

SUMMARY OF THE INVENTION

[0006] In view of the shortcomings of the prior art, the inventor of the invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally invented a slide linking apparatus in accordance with the present invention.

[0007] Therefore, it is a primary objective of the present invention to provide a feasible solution and overcome the foregoing problems by providing a slide linking apparatus, and the apparatus comprises a fixing base fixed onto an internal side of a chassis, a positioning member disposed at an end of the fixing base, an aslant blocking plate disposed at a specific position of the fixing base, and a first rail and a second rail embedded into the fixing base and engaged with each other. The first rail includes a swing member disposed proximate to an end of the positioning member, and another end of the swing member is embedded into a slide groove, and the second rail includes a link member for pressing against the swing member, such that when the second rail slides outward, the link member presses against the swing member to drive the first rail to move accordingly until the swing member is pressed downward by the aslant blocking plate to swing and separate from the link member, and the first rail stops moving forward. On the other hand, if the second rail is moved backward, the first rail is driven to move accordingly. When the swing member moves backward and presses against the positioning member of the fixing base, the swing member slides upward to resume the link member back to the extending portion of the swing member. Since the second rail and the first rail are moved synchronously, the pressure exerted on the second rail connected to an object will be reduced, so as to prevent possible deformations.

[0008] Another objective of the present invention is to provide a slide linking apparatus, whose swing member has a groove disposed at an extending portion and corresponding to a link member, such that the link member can be accommodated by the groove of the swing member, so as to press against the swing member tightly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Referring to FIGS. 1 and 2 for a slide linking apparatus in accordance with the present invention, the apparatus is used for a moving object or a drawer in a chassis, and the apparatus comprises an I-shape fixing base 10 which is an I-shape slice body in this embodiment, and an end of the fixing base 10 has a protruding ear 11, and the protruding ear 11 has a through hole 111 for passing a fixing member to fix the fixing base 10 onto an internal wall (not shown in the figure) of the chassis, and another end has a positioning member 12 which is a stamped slice body perpendicular to the fixing base 10 in this embodiment, and the fixing base 10 has an aslant blocking plate 13 with a specific inclination and disposed at a specific position, and the aslant blocking plate 13 keeps a specific distance from both ends of the fixing base 10.

[0022] Further, the fixing base 10 has a first rail 20 and a second rail 30 embedded thereon, and the first and second rails in this embodiment are I-shape slice bodies and engaged with each other, wherein an end of the first rail 20 has an embedding groove 21 embedded with a swing member 22, and an end of the swing member 22 has a disc base 221 embedded into the embedding groove 21, such that the swing member 22 will not be separated from the first rail 20, and another end of the disc base 221 has an extending portion 222 extended outward from the disc base 221. A groove 223 is built and sunken at a connecting position of the extending portion 222 and the disc base 221, and the extending portion 222 has an embedding portion 224 protruded from an end away from the disc base 221, and the embedding portion 224 is embedded precisely into a slide groove 23 which is an arc groove hole in this embodiment, such that the extending portion 222 can be latched by the embedding portion 224 and will not be separated from the slide groove 23, but the extending portion 22 can slide in the slide groove 23. Further, another end of the first rail 20 has a protruding plate 24 and two symmetric extending plates 25 extended outward from the first rail 20.

[0023] Another end of the second rail 30 has a stamped link member 31 extended towards the first rail 20, and the link member 31 is a slice body in this embodiment and contained in the groove 223 of the swing member 22 and presses against the extending portion 222 of the swing member 22, and the second rail 30 has a slice body 32 disposed at a specific position corresponding to the protruding plate 24, and the second rail 30 has symmetric side stopping plates 33 disposed on a lateral side and corresponding to the first rail 20.

[0024] Referring to FIGS. 3, 3A, 3B, and 3C, the first rail 20 and second rail 30 are embedded onto the fixing base 10 first, and then the fixing base 10 is fixed onto an internal side of the chassis, and an object is fixed onto the second rail 30, such that when the object is pulled outward, the link member 31 will move all the way into the groove 223 of the swing member 22 to prop the extending portion 222, and the second rail 30 is moved outward accordingly with the object, and the first rail 20 is also moved accordingly (as shown in FIG. 3A). In the process of sliding the second rail 30, the weight of the object is supported by the first rail 20 instead of being supported solely by the second rail 30, and thus the invention can prevent possible deformations of the rails 20, 30. If a user wants to pull out the object completely and the first rail 20 moves outward accordingly with the second rail 30, the extending portion 222 of the swing member 22 of the first rail 20 will touch the aslant blocking plate 13 of the fixing base 10. With a force at a specific inclination pressing onto the aslant blocking plate 13, the extending portion 222 moves from an end of the slide groove 23 to another end (as shown in FIGS. 3B and 3C), and thus the first rail 20 will stop at that position, and the link member 31 of the second rail 30 will be separated from the swing member 22, and will continue to move outward until the slice body 32 touches the protruding plate 24 (not shown in the figure) and then will stop moving further.

[0025] Referring to FIGS. 4, 4A, 4B, 4C and 4D, the second rail 30 will move back synchronously if a user wants to push the object back into the chassis, and the side stopping plate 33 on the second rail 30 will be moved to press the first rail 20 on the extending plate 25, and further drive the first rail 20 to move back (as shown in FIG. 4). While the first rail moves back into the chassis, the swing member 22 of the first rail 20 will be in contact with the positioning member 12 of the fixing base 10 (as shown in FIGS. 4A, 4B and 4C), such that the swing member 22 moves from an end of the slide groove 23 to another end. In the meantime, the embedding portion 224 of the swing member 22 also moves upward along the slide groove 23, such that the extending portion 222 of the swing member 22 is lifted, and the link member 31 is returned into the groove 223, so as to resume the second rail 30 to its original position.

[0026] In summation of the description above, the object, shape, structure of the present invention are novel and improve over the prior art and thus is duly submitted for the patent application. While the invention has been described by means of specific embodiments, modifications and variations could be made by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
