The following is a description of the present invention. The invention will firstly be described with reference to one exemplary structure. Some variations will then be described as slot as with the advantages of the present invention. A preferred method of fabrication will then be discussed. An alternate, asymmetric embodiment will then be described along with the variations in the process flow to fabricate this embodiment.
Referring to FIG. 1, a support apparatus with height adjustment primarily comprises a first body 1, a second body 2, and a tenon 3. Therein, the first body 1 includes a first plate body 11, a second plate body 12 and a structure body constructed by a guiding part 13 defined by two plate bodies formed of a first plate body 11 and a second plate body 12; the first plate body 11 has voided part 11 a which penetrates and fits the tenon 3; the second plate body 12 has a button 12a, which co-operates with the tenon 3 and penetrates and slides in a confined manner on the second plate body 12; and the guiding part 13 has two parallel surfaces and is used to mount and slide on the second body 2.
Additionally, the second body 2, which is a plate body and is installed into the guiding part 13 of the first body 1 with vertically up/down sliding method, includes a vertically extending rectangular hole 21 and a plurality of slots 22 arranged along the rectangular hole 21.
Furthermore, the tenon 3, which is axially mounted on a voided part ha of the first plate body 11, has a top part 31 formed on the top of the tenon 3, and an under flange 32 formed on one surface of bottom of the tenon 3 so as to selectively be locked in a slot 22 of the second body 2; therein, a button 12a of the second plate body 12 is mutually co-operating; a spring is set and respectively connected to the second plate body 12 and the tenon 3 at two ends so as to provide an elastic force to maintain the tenon tending to a first state, and to limit the tenon reaching a second state by operating the button 12a; so the tenon 3 becomes a structure for selecting vertically upward or downward motion of the second body 2, and the button 12a is operated in coordination with rectangular hole 21, so no mechanical interference is produced by the button 12a and the first plate body 11.
FIG2 shows a local cutaway view of the tenon 3 of a support apparatus with height adjustment according to the present invention; therein the tenon 3 is at the first state; FIG3 shows a local cutaway : * *view of the tenon of a support apparatus with height adjustment according to the present invention; * * therein the tenon 3 is at the second state; FIG4 shows a local cutaway view of the tenon 3 of a support **apparatus with height adjustment after descending according to the present invention; therein the * :* Jenon 3 is back to the first state.
* : * : Referring to FIG2, FIG3 and FIG.4, according to the embodiment of the present invention, partial elements for carrying out and the achievement of the operating mechanism will be explained * ** s the following. *. * * S S
* According to the present invention, the tenon 3 is axially mounted on the voided part 11 a with an axis 34; a spring 33 is connected to the top of the axis 34 at one end, and connected to the top of the button 12a of the second plate body 12 at the other end. Thus, the tenon 3 is at the first state, as the spring 33 is at the position of a balanced state; the top part 31 is separate from the slot 22 of the second body 2; the under flange 32 is interfered with the slot 22 of the second body 2. The tenon 3 is at the second state as pressing the button I 2a, and elastic force in an opposite direction is produced from the pressure; the under flange 32 is separated from the slot 22 of the second body 2, and the under flange 32 is interfered with the slot 22 of the second body 2.
Besides, a height difference between the position of the top part 31 and the position of the under flange 32 of the tenon 3 must be greater than or equal to N times the interval of the slots 22 on the second body 2, but smaller than or equal to M times the interval of the slots 22 of the second body 2, therein M is greater than N. Referring to FJG2, according to the embodiment of the present invention, a height difference between top part 31 and under flange 32 of the tenon 3 is greater than adding a multiple of the central distance and the interval distance between slots 22 of the second body 2, but smaller than or equal to twice the central distance between slots 22 of the second body 2.
Referring to FIG.3, the tenon 3 will change into the second state as pushing the button 12a of the second plate body 12, so the under flange 32 of the tenon 3 will exit the first slot 22a; however, the top part 31 of the tenon 3 is interfered with the third slot 22c until the second body 2 descends along the guiding part 13 of the first body 1, down to the top of the third slot 22c and stops at the top part 31 of the tenon 3.
Referring to FIG4, the tenon 3 returns to the first state as releasing the button 12a of the second plate body 12. Thus the top part 31 of the tenon 3 exits the third slot 22c, but the under flange 32 is interfered with the second slot 22b until the second body 2 descends to the second slot 22b and stops at the under flange 32 of the tenon 3.
Therefore, the tenon 3 is changed from the first state to the second state; after going back to the first state, the second body 2 along the guiding part 13 of the first body I descends one unit central distance between the second body; pressing the button 1 2a of the second plate body 12 once, and it descends one unit distance.
: ** FIG5 shows an exploded perspective view of a support apparatus with height adjustment of the *::.: second preferred embodiment according to the present invention; FIG6 shows a local cutaway view ****of the damping device in FIG5 according to the present invention; therein the tenon is at the first position; FIG7 shows a local cutaway view of the damping device in FIG5 according to the present * invention; therein the tenon is at the second position.

Referring to FIGs.5, 6 and 7, according to the embodiment of the present invention described * . above, a damping device 23 is set to provide damping force for the second body 2 during the descending process, so as to slow down the descending speed of the second body 2 for stabilizing descending of the damping device 23. According to another preferred embodiment, the damping device is set into the second body 2, and constructed by a damping slot 231 and damping block 232 with mutual cooperation. Therein, the damping slot 231 is formed by caving in an inside surface of the second body 2, and the opening of the damping slot is formed to face to the first plate body 11; a damping block 232 is located at the bottom of the damping slot 231; a damping block 232 is set inside the damping slot 231 with a vertically sliding way, and a cuneal part 232a is formed and fitted on the top of the damping slot 231; as the cuneal part 232a of the damping block 232 is connected into the damping slot 231 of the cuneal part 232a, contact forward force between the damping block 232 and the first plate body 11 increases.
Additionally, an elastic element 233 is set to connect both the damping slot 231 and the damping block 232 of the damping device 23; the damping block 232 tends to go back to the first position.
Referring to FIG.6, in accordance with the second embodiment of the present invention, as the second body 2 and the guiding part 13 of the first body 1 are relatively static, the damping slot 231 and damping block 232 of the damping device 23 ofthe second body 2 are located at the first position; because contact force between cuneal slot 231 a of the damping slot 231 and the damping block 232 of the cuneal part 232a is smaller, forward contact force between the damping block 232 and first plate body 11 is smaller; friction between the damping block 232 and the first plate body 11 is also smaller; the friction also takes place as the second body 2 rises relatively compared to the guiding part 13 of the first body 1.
Referring to FIG 7, as the second body 2 descends relatively compared to the guiding part 13 of the first body 1, the damping block 232 is drawn back because of friction of the first plate body 11 and moves up along the cuneal slot 231a of the damping slot 231 with the resisting elastic element 233; and gradually increasing contact force between the damping 231 a of the damping slot 231 and the cuneal part 232a of the damping block 232 occurs, until the damping slot 231 and the damping block 232 of the damping device 23 of second body 2 is located at the second position. Therefore, the forward contact force between the damping block 232 and the first plate body 11 is greater; friction between the damping block 232 and first plate body 11 is also greater; and the descending acceleration of the second body 2 will be slowed down to achieve the effect of a buffer.
FIG8 shows a cutaway view of a support apparatus with height adjustment of the third preferred embodiment according to present invention; a coupling stage 4 and a leg 5 are added to locate a LCD screen 6; therein, the coupling stage 4 is mounted on the top of the second body 2; and the shackle 41 : *. . structure is formed on top; the leg 5 is the supporting structure mounted on bottom of the first body 1 * and is used to support and maintain balance of the whole support apparatus with height adjustment "S. ind the LCD screen 6; the LCD screen 6 is axially coimected to the coupling stage 4; therefore, çlirection of the LCD screen is changed by the axial structure of the coupling stage 4; and the height of "the screen is changeable by a relative motion of the second body 2 and the first body 1.
