    DETAILED DESCRIPTION OF EMBODIMENTS
  • With reference to FIGS. 1 through 4, there is shown a tool-displaying apparatus 10 in accordance with a first embodiment of the present invention. The tool-displaying apparatus 10 includes a base 11, a tray 12, two hinges 13 and two identical linkages 20. The base 11 is shaped like a frame for use to support a photograph. That is, the base 11 includes two left and right bars extending between front and rear bars.
  • The tray 12 may simply be a plate made with a planar upper face. However, the tray 12 may include cavities defined in the upper face for receiving tools. A front edge of the tray 12 is pivotally connected to the front bar of the base 11 by the hinges 13. The size of the tray 12 is marginally smaller than that of a space defined by the base 11 so that the tray 12 is located in the space defined by the base 11 when the tray 12 is located laid down as shown in FIG. 2.
  • Each of the linkages 20 includes a bracket 14, two levers 21 and 24, two washers 25 and a sliding element. The bracket 14 is an L-shaped element with two sections extending perpendicular to each other.
  • The lever 21 is preferably a metal strip with a slot 22 longitudinally defined therein and a cutout 23 transversely defined therein. In detail, the slot 22 is defined between upper and lower edges, and the cutout 23 is defined in the upper edge of the slot 22.
  • The lever 24 is preferably a metal strip. The sliding element includes a head 27 formed on a body 26. The diameter of the body 26 of the sliding element is marginally smaller than the width of the slot 22. The diameter of the head 27 of the sliding element is considerably larger than the width of the slot 22. The thickness of the head 27 is marginally smaller than the thickness of the washers 25.
  • In assembly, the first section of the bracket 14 is secured to the right or left bar of the base 11 by screws, pins or rivets for example. A rear end of the lever 24 is pivotally connected to the second section of the bracket 14 by a screw, pin or rivet for example. The body 26 of the sliding element is inserted through the slot 22 before the sliding element is connected to a front end of the lever 24 by a screw, pin or rivet for example. Thus, the lever 21 is restrained between the head 27 of the sliding element and the lever 24. Accordingly, the lever 21 is connected to the lever 24 by the sliding element. The washers 25 are located between a left or right edge of the tray 12 and the lever 21 before two screws, pins or rivets are driven into the left or right edge of the tray 12 through the washers 25 and front and rear ends of the lever 21.
  • In use, the tray 12 can be laid down relative to the base 11 as shown in FIG. 1 or raised relative to the base 11 as shown in FIG. 2. As the tray 12 is moved relative to the base 11 between the positions shown in FIGS. 1 and 2, the lever 21 is pivoted together with the tray 12 and the lever 24 is pivoted relative to the base 11 while the body 26 of the sliding element is moved along the slot 22 defined in the lever 21. As shown in FIG. 1, the tray 12 is located in the space defined by the base 11 as the tray 12 is laid down relative to the base 11. As shown in FIG. 2, the tray 12 is kept raised relative to the base 11 as the body 26 of the sliding element is located in the cutout 23 defined in the lever 21.

Accordingly, the middle tray 52 is raised or lowered as the upper base 56 is raised or lowered.
  • Each of the telescopic posts 60 includes three tubes 61, 62 and 63 telescopically connected to one another. An external diameter of the middle tube 62 is marginally smaller than an internal diameter of the lower tube 61 so that the middle tube 62 can partially be inserted in the lower tube 61. An external diameter of the upper tube 63 is marginally smaller than an internal diameter of the middle tube 62 so that the upper tube 63 can partially be inserted in the middle tube 62.
  • The lower tube 61 is connected to the lower base 53. The middle tube 62 is connected to the middle base 55. The upper tube 63 is connected to the upper base 56. Thus, the tool-displaying apparatus 50 can be moved between the positions shown in FIGS. 8 and 14 as the telescopic posts 60 are extended or shrunk.
  • With reference to FIG. 11, an upper spring-biased detent unit is provided in an upper section of the upper tube 63. The upper spring-biased detent unit includes a plug 64, an upper detent 66 and an upper spring 67.
  • The plug 64 includes a stepped tunnel 65 transversely defined therein. The stepped tunnel 65 includes a thick section and a thin section so that an annular shoulder is formed between the thick and thin sections. The plug 64 is fit in the upper section of the upper tube 63.
  • The upper detent 66 includes a rounded tip formed at an end and an annular rib formed at an opposite end. The upper detent 66 is movably inserted in the thin section of the stepped tunnel 65. Now, the rounded tip of the upper detent 66 is located outside the upper base 56 through an aperture defined in the upper section of upper tube 63 and an aperture defined in the upper base 56. The annular rib of the upper detent 66 is located against the annular shoulder of the stepped tunnel 65 so that upper detent 66 is retained in the stepped tunnel 65. The upper detent 66 may be hollow for receiving a section of the upper spring 67.
  • The upper spring 67 is a compression spring and, more particularly, a helical spring. The upper spring 67 includes an end in contact with the upper detent 66 and an opposite end in contact with the upper section of the upper tube 63. Thus, the upper spring 67 biases the upper detent 66 and tends to keep the rounded tip of the upper detent 66 outside the upper base 56, thus positioning the upper base 56 relative to the upper tube 63.
  • With reference to FIG. 10, the upper base 56 is lifted. The upper tray 52 is lifted together with the upper base 56 but not pivoted from the upper base 56. The upper tubes 63 are extended from the middle tubes 62 because of the upper spring-biased detent units operated as described above with reference to FIG. 11. The middle tray 52 is pivoted from the middle base 55 as the sliding elements 58 of the middle tray 52 slide in the slots 57 of the upper base 56.
  • With reference to FIG. 13, a lower spring-biased detent unit is provided in a lower section of the upper tube 63. The lower spring-biased detent unit includes a lower detent 68 and a lower spring 69.
  • The lower detent 68 includes a rounded tip formed at an end. The lower detent 68 is movably inserted in an aperture defined in a lower section of the upper tube 63, an aperture defined in an upper section of the middle tube 62 and a related one of the apertures 59 defined in the middle base 55. Now, the rounded tip of the lower detent 68 is located outside the middle base 55 via the aperture defined in the lower section of the upper tube 63, the aperture defined in the upper section of the middle tube 62 and the related aperture 59.
  • The lower spring 69 is a bent leaf spring with an end connected to the lower detent 68 and another end attached to the lower section of the upper tube 63. Thus, the lower spring 69 biases the lower detent 68 and tends to keep the rounded tip of the lower detent 68 outside the middle base 55, thus positioning the middle base 55 relative to the upper tube 63 and the middle tube 62.
  • With reference to FIG. 12, the upper base 56 is lifted to a limit. Accordingly, the middle tray 52 is pivoted from the middle base 55 to a limit. Hence, the middle base 55 is lifted to a limit. The middle base 55 is retained in this position because of the lower spring-biased detent unit operated as described above with reference to the FIG. 13.
  • Although not shown, another spring-biased detent unit like the lower spring-biased detent unit is provided in the lower section of the middle tube 62 for positioning the middle tube 62 relative to the lower tube 61.
  • The cover 70 includes an array of apertures 71 defined therein and a tab 72 extending from an edge thereof. The cover 70 is pivotally connected to the upper tray 52. The cover 70 can be pivoted relative to the upper tray 52 between the positions shown in FIGS. 9 and 14. The tab 72 is located against an edge of the upper tray 52 when cover 70 is pivoted from the upper tray 52 to a limit. Thus, the cover 70 is positioned relative to the upper tray 52. A tool T can be hung on a hanger partially inserted in one of the aperture 71.
  • With reference to FIG. 15, the cover 70 is pivoted backward from the upper tray 52 beyond a vertical line extending the axis of the pivotal connection of the cover 70 to the upper tray 52. An angle θs defined between a face of the cover 70 and the vertical line. The angle θ is 1 to 20 degrees. Thus, the weight of the tool T would result in a torque that tends to pivot the cover 70 backward from the upper tray 52. Accordingly, the cover 70 cannot be pivoted forward to the upper tray 52.
  • The tool-displaying apparatus includes only one middle layer in accordance with the fourth embodiment. However, the tool-displaying apparatus may include two middle layers or more in accordance with another embodiment.
  • The present invention has been described via the detailed illustration of the embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Therefore, the embodiments shall not limit the scope of the present invention defined in the claims.
