  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • [0016]
    The present invention is now to be described in detail hereinafter by way of a preferred embodiment in reference to drawings.
  • [0017]
    Referring to FIG. 1, there is shown a preferred embodiment of a track set in accordance with the present invention. The inventive track set includes a component 1, a track member 2 and a retaining member 3.
  • [0018]
    The component 1 may be a side-wall of a drawer or of a piece of furniture, with two positioning members 11 mounted on the side-wall in a place where the track member 2 is intended to be attached to the component 1. The positioning members 11 can be any fastenings that each have an enlarged head, such as screws.
  • [0019]
    The track member 2, which may be made into various configurations, is provided with two positioning holes 21, each having a large portion and a narrow portion communicating with the large portion. As clearly shown, the large portion has a diameter larger than a diameter of the enlarged head of the positioning member 11 but the narrow portion has a width smaller than the diameter of the enlarged head of the same positioning member 11.
  • [0020]
    This allows the positioning members 11 to be easily extended into the large portions of the positioning holes 21 and moved into the narrow portions as the result of a longitudinal movement of the track member 2 relative to the component 1, thereby holding the track member 2 between the component 1 and the two enlarged heads of the positioning members 1 and thus preventing the track member 2 from separating from the component 1 in a direction in which the two positioning members 11 extend from the component 1.
  • [0021]
    The retaining member 3 is pivotally connected to the track member 2 by means of a pivot 33, such as a pin, and has a first end 31 and a second end 32 at respective sides of the pivot 33. The retaining member 3 is pivotally connected in a location so adjacent to the large portion of one positioning hole 21 that the first end 31 of the retaining member 3 may be moved upward and downward about the pivot 33.
  • [0022]
    The retaining member 3 is additionally spring-loaded by a back-moving spring 34, e.g. a torsion spring mounted around the pivot 33 or, preferably, a curved wire spring which has a first end engaged with the second end 32 of the retaining member 3 and a second end engaged with an orifice 22 defined in the track member 2. The retaining member 2 is spring-loaded in such a way that the first end 31 of the retaining member 3 is normally positioned near the edge of the large portion of the positioning hole 21 and tends to move back to the position after the first end 31 is moved away from the positioning hole 21.
  • [0023]
    The retaining member 3 is designed to be turned about the pivot 33 within a predetermined angular range. In the illustrated embodiment, the retaining member 3 is formed between its ends 31 and 32 with a top 35 that can be brought into contact with a part of the track member 2, for example, a right-angled upper wall 23 of the track member 2, as shown in FIG. 3, while the first end 31 of the retaining member 3 is shaped to slope downward and can be brought into contact with the upper wall 23 when the first end 31 is moved far away from the hole 21. This surely limits the turning of the retaining member 3 within the predetermined angular range.
  • [0024]
    Referring to FIGS. 2 and 3, the track member 2 can be attached to the component 1 by extending the positioning members 11 into the large portions of the positioning holes 21 until their enlarged head pass through the two large portions. At this time, the first end 31 of the spring-loaded retaining member 3 is still positioned near the edge of the large portion of one positioning hole 21.
  • [0025]
    Referring to FIG. 4, the track member 2 is then moved relative to the component 1 in a longitudinal direction as designated by an arrow shown in FIG. 4, so that the positioning members 11 are moved from the large portions of the positioning holes 21 into the narrow portions. During the meantime, the first end 31 of the retaining member 3 is moved upward by the enlarged head of one positioning member 11.
  • [0026]
    Referring to FIGS. 5 and 6, as soon as the positioning members 11 are moved fully into the narrow portions of the positioning holes 21, the first end 31 of the retaining member 3 is lowered by the action of the back-moving spring 34 and is engaged with the enlarged head of one positioning member 11 in a point about 9 o'clock, thereby holding the positioning members 11 motionlessly in the narrow portions of the positioning hole 21 and thus preventing the track member 2 from moving in its longitudinal direction with respect to the component 1.
  • [0027]
    Being movable neither in its longitudinal direction due to the retaining member 3 nor in its lateral direction due to the enlarged heads of the positioning members 1, the track member 2 is then fixedly attached to the component 1.
  • [0028]
    The track member 2 can be removed from the component 1 by depressing the second end 32 of the retaining member 3. This forces the first end 31 of the retaining member 3 to be lifted and disengaged from the enlarged head of the positioning member 1, as clearly shown in FIG. 4. As a result, the track member 2 can be moved relative to the component 1 in its longitudinal direction, making the positioning members 11 move from the narrow portions 21 back to the large portions of the positioning holes, where the track member 2 can be easily removed from the component 1.
  • [0029]
    From the foregoing, it is apparent that this invention has the advantage of enabling the track member to be attached to the component easily and quickly. Furthermore, the track member can be removed from the component simply by depressing the second end of the retaining member. This depression disengages the first end of the retaining member from the positioning member and allows the track member to moved relative to the component until the positioning members move back to the large portions of the positioning holes, where the track member can be removed from the component. In one word, the inventive track set can be attached to and removed from the component easily and quickly.
  • [0030]
    While the principles of this invention have been disclosed in connection with specific embodiments, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
