1. Field of the Invention
The present invention relates to a slide track, particularly a track-based synchronous interlinking device used in a synchronous interlinking mechanism and facilitating superior smooth and accurate slides and economic efficiency.
2. Description of the Related Art
Cabinets with pull-out drawers installed have been extensively applied in all kinds of storage equipment currently wherein each of the drawers to be conveniently pulled or pushed by users is usually integrated with tracks at its both sides for positioning and guiding the drawer, for instance, an internal track and an external track between which a ball bearing carriage is installed. As one component installed between slide tracks for a smooth sliding operation, the ball bearing carriage passing through a first track usually collides a second track, which is not synchronously interlinked to the first one, for continuous movement, causing vibrations, and deteriorating a sliding process.
A technique based on synchronous triple-track interlinking tracks to overcome the above drawbacks has been available now. As shown in
The track-based synchronous interlinking mechanism based on the prior art for an effective synchronous interlinking operation still has some drawbacks deserved to be corrected. For example, slide tracks' heights are not reduced because of a toothed wheel 95 and a row of ruler-like sawteeth 913, 932 installed between slide tracks; a toothed wheel and a row of ruler-like sawteeth, both of which are high-cost components, are uneconomic and unideal design; down force (weight) induced by the tilted external track deviates the lower track's axle and causes an unsmooth operation or departure of the track assembly from a cabinet in the case of a toothed wheel and a row of ruler-like sawteeth manufactured with rigid material. Therefore, the abovementioned drawbacks in a conventional track-based synchronous interlinking mechanism deserve to be overcome by persons skilled in the art.
Accordingly, the inventor having considered imperfect structural design and drawbacks of the prior art and attempted to optimize a solution, that is, a track-based synchronous interlinking device moving smoothly and accurately and conforming to a demand for economic design, has studied and developed the present invention for benefiting the general public and promoting development of the industry.
The present invention is intended to provide a track-based synchronous interlinking device effectively satisfying a synchronous triple-track interlinking operation during relative slides, keeping superior smooth and accurate slides, conforming to economic efficiency and a demand for better track design, and positively promoting practicability, texture perception, and competitiveness of a product.
The present invention is based on the following technical measures to realize the above purposes: a lower track on which a knurl pattern is designed; a central track completing slides relative to the lower track; an external track completing slides relative to the central track and decorated with a knurl pattern; a synchronous interlinking device comprising a roller bracket positioned at the central track and a roller which is a flexible or elastic component pivoted to the roller bracket and allows its both sides to contact the lower track's knurl pattern and the external track's knurl pattern, respectively.
For technical features and effects in terms of the present disclosure completely comprehended and recognized, the preferred embodiments and accompanying drawings are thoroughly described hereinafter.
Referring to
The synchronous interlinking device 50 comprises a roller bracket 51 and a roller 52: the roller bracket 51 comprises two locators 511 which are located at both sides and inserted into and positioned at the pilot holes 23 on the central track 20 and develops a hollow roller accommodation space 512 in which two raised joining columns 513 corresponding to each other and centrally situated at both laterals parallel to the central track 20 are designed; the roller bracket 51 further develops a hollow side compartments 514 at both ends of the roller accommodation space 512 for enhanced compressive elasticity and comprises two resisting parts 515 outside the locators 511 for stronger stability during positioning; the roller 52 featuring flexibility and elasticity has an axial hole 521 to which the two joining columns 513 in the roller accommodation space 512 are pivoted and positioned; moreover, the roller 52 positioned in the roller bracket 51 has a diameter larger than the inner depth of the roller accommodation space 512 and protrudes from the roller accommodation space 512 (roller bracket 51).
Moreover, the roller 52 which has been pivoted to and positioned in the roller bracket 51 allows its both sides to resist the knurl pattern 14 on the lower track 10 and the knurl pattern 32 on the external track 30. As such, friction induced by contacts between the roll 52 and the knurl patterns 14, 32 facilitates relative interlinking.
Referring to
The roller 52 whose diameter is smaller than that of a known toothed wheel is effective in reducing the whole track assembly's height and in favor of high applicability and a demand for designing a compact slide track. The roller 52 manufactured with soft material featuring flexibility or elasticity is able to absorb force induced by theexternal track 30 which tilts (
It can be seen that the present invention of a track-based synchronous interlinking device effectively satisfies a synchronous triple-track interlinking operation during relative slides, keeping superior smooth and accurate slides, conforming to economic efficiency and a demands for better track design, and positively promoting practicability, texture perception, and competitiveness of a product.
Accordingly, the present invention significantly meets patentability and is applied for the patent. However, the above descriptions are only preferred embodiments which do not limit the scope of the present invention; any equivalent change or improvement without departing from spirit of the present invention should be incorporated in claims herein.
