DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to FIG. 1 through FIG. 3, according to the present embodiment, a transformable table primarily has a base 10, a lifting mechanism 20, a transformable platform 30, an interlocking member 40 and a locking mechanism 50.

(10) The base 10 is a fixed frame composed of plural supports, and is at the bottom provided with plural casters 16 for horizontal displacement. The lifting mechanism 20 is connected to the base 10 and a platform pivot 32 of the transformable platform 30, and is allowed to move up and down with respect to the base 10, so as to enable the platform pivot 32 to move between an upper position and a lower position. The transformable platform 30 moves up and down with the platform pivot 32, and has its part at one side of the platform pivot 32 defined as the first part 33 herein (e.g. the left part against the dotted line drawn across the platform pivot 32 in FIG. 1). The interlocking member 40 connects the first part 33 to the base 10, and works to draw the first part 33 to drive the transformable platform 30 to pivot as the transformable platform 30 moves up and down. In this way, the transformable platform 30 forms different angles when positioned at different heights, thereby satisfying various user needs. The locking mechanism 50 serves to releasably lock the lifting mechanism 20 and is operable to users.

(11) In the present embodiment, the frame of the base 10 primarily comprises two bottom bars 15, two first braces 11, two beams 12, and a retaining plate 13. The two bottom bars 15 each has two casters 16. The two first braces 11 are vertically mounted on the bottom bars 15, respectively. The two beams 12 are connected between the two first braces 11 for maintaining the relative position between the two first braces 11. One of the beams 12 is located higher (as shown in FIG. 3), while the other beam 12 is located lower. The retaining plate 13 stands upright between the two beams 12 to provide partition. In addition, a casing 14 for receiving the locking mechanism 50 is located above the retaining plate 13.

(12) The lifting mechanism 20 primarily has two second braces 21. The two second braces 21 are each combined with one said first brace 11 so as to form a telescopic pole, wherein each said second brace 21 can move up and down with respect to and along the corresponding first brace 11. Referring also to FIG. 4, the first brace 11 and the second brace 21 are hollow tubes that can be telescoped, and an extension driver 22 is provided therein. The extension driver 22 has its two ends fixed to the first brace 11 and the second brace 21, respectively, for driving the second brace 21 to move against the first brace 21. In a practical embodiment, the extension driver 22 is a gas lift that provides the required driving force.

(13) The transformable platform 30 is supported by the base 10 and defines a flat surface 31. It is provided with the platform pivot 32 that extends transversely across its middle part, so that the transformable platform 30 can pivot against the platform pivot 32. The platform pivot 32 has its one side herein defined as a first part 33. The platform pivot 32 has its two ends each connected to one said second brace 21, so that it can move up and down with the second brace 21 between an upper position and a lower position.

(14) The interlocking member 40 has a plate-like shape, and is located below the transformable platform 30, with its one side pivotally connected between the two first braces 11 and its opposite side pivotally connected to the ends of the first part 33. In the present embodiment, the interlocking member 40 has its opposite side equipped with two pivotal links 41 that are connected to the first part 33 of the transformable platform 30 at places near the ends. The two pivotal links 41 is driven by the up and down movements of the transformable platform 30, and draws the first part 33 to make the transformable platform 30 pivot correspondingly. When the transformable platform 30 stop moving vertically, or, when the platform pivot 32 stops moving, the transformable platform 30 stops at an angle it is posed at that time. In the present embodiment, when the transformable platform 30 and the platform pivot 32 is in their lower positions, the transformable platform 30 is lowered and the surface 31 has pivoted to a substantially horizontal angle, making it suitable for working as a tabletop (as shown in FIG. 1). When the transformable platform 30 and the platform pivot 32 are in their upper positions, the transformable platform 30 is lifted and the surface 31 pivots to an upstanding posture. At this time, the interlocking member 40 has pivoted to an upstanding posture, so that it is vertically aligned with and located between the transformable platform 30 and the retaining plate 13. In other words, the transformable platform 30, the interlocking member 40, and the retaining plate 13 are coplanar without overlapping each other are coplanar without overlapping each other, and jointly form an upstanding, single layer panel, which can be used as a screen or a bulletin board (as shown in FIG. 2). With the ability to change its profile, the transformable table can be used diversely.

(15) Referring to FIG. 5 and FIG. 6 together, the locking mechanism 50 primarily comprises two spring-loaded pulls 51, two ropes 52, and a knob 53. Each of the spring-loaded pulls 51 is installed on a corresponding said first brace 11, and releasably locks the second brace 21 with respect to the first brace 11. When the bolt portion of the spring-loaded pull 51 is inserted into the positioning hole 211 of the second brace 21, the spring-loaded pull 51 now in its locked state can keep the relative position between the second brace 21 and the first brace 11. When the bolt portion of the spring-loaded pull 51 is pulled out from the positioning hole 211 of the second brace 21, the foregoing locked state is released (unlocked). At this time, the second brace 21 is allowed to move with respect to the first brace 11, until the positioning hole 211 of the second brace 21 is moved to a site it is aligned with the spring-loaded pull 51 at which site the spring-loaded pull 51 automatically engages it and the locked state is recovered. In the present embodiment, the second brace 21 has at least a positioning hole such formed that when it is in the lower position, the positioning hole corresponds to the spring-loaded pull 51. Each of the two ropes 52 is connected to one said corresponding spring-loaded pull 51 and the knob 53, so that the ropes 52 can be controlled by the knob 53 to pull and release the spring-loaded pulls 51, thereby allowing up and down movements. The knob 53 comprises a fixed part having a retaining recess 531 and a rotatable part having a protrusion 532 that limits how much the knob 53 can rotated when operated. The two ropes 52 are connected to the rotatable part of the knob 53, respectively. When the knob 53 rotates, it drives the two ropes 52 to pull the spring-loaded pull 51 and dismisses the locked state.

(16) In a practical embodiment, the second brace 21 may be provided with plural positioning holes 211 for the spring-loaded pull 51 to selectively engage. The vertical position of the second braces 21 depending on the selected positioning holes 211 determines the angle of the surface 31 of the transformable platform 30 after its pivotal movement. By selecting different positioning holes 211, the transformable platform 30 can be posed differently for various applications.

(17) Referring to FIG. 7 and FIG. 8 together, in the lower position, the spring-loaded pulls 51 of the locking mechanism 50 are inserted into the positioning holes 211 of the second brace 21 to maintain the locked state. At this time, the surface 31 of the transformable platform 30 has pivoted to a substantially horizontal angle (as shown in FIG. 1 and FIG. 7) and may be used as a tabletop. When transformation is desired, it can be easily achieved by rotating the knob 53, which then drives the ropes 52 to pull the spring-loaded pull 51 and unlock the lifting mechanism 20. To this point, the extension driver 22 (i.e. the gas lift) can act to automatically raise the second brace 21 from the first brace 11, until they reach the upper position (as shown in FIG. 2 and FIG. 8). Meanwhile, the second braces 21 drive the transformable platform 30 to move upward, and the transformable platform 30 is drawn by the interlocking member 40 to pivot against the platform pivot 32. When the surface 31 of the transformable platform 30 pivots to the upstanding posture, the transformation is completed, and the transformable table can now be used as a screen or a bulletin board. For turning it back to a table, a user can push the transformable platform 30 downward with a little effort that is sufficient to overcome the acting force of the extension driver 22 so that the lifting mechanism 20 can move downward. When the lifting mechanism 20 arrives at the lower position, the spring-loaded pulls 51 automatically engage the positioning holes 211 of the second brace 21 to lock the surface 31 of the transformable platform 30 at its horizontal position to be used as a tabletop (as shown in FIG. 1 and FIG. 7).

(18) To sum up, the disclosed transformable table is structurally simple, easy to operate and versatile in use, making it novel, inventive and patent-worthy. The present invention has been described with reference to the preferred embodiments and it is understood that the embodiments are not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
