However, this embodiment does not limit the direction in which the strut groups 130A, 130B can be driven.

FIG. 5 to FIG. 7 are schematic diagrams showing the state transition of the lifting table mechanism, which is illustrated in the right side view of FIG. 1 , and the strut group 130B on the other side is also actuated in the same manner, and thus will not be described again, and The component 114A of the first bracket 110 is see-through (i.e., depicted in dashed outline) to clearly define the associated component relationships there. However, in this embodiment, the beam 132 is laterally connected between the first struts 134A and 134C, so that the two struts 130A, 130B can be synchronized. Hereinafter, only the operation mode of the strut group 130A will be described with reference to FIGS. 5 to 7.

The first pole 134A has a first connecting end E1 and a second connecting end E2 opposite to each other. The first connecting end E1 is pivotally connected to the component 114A of the first bracket 110, and the second connecting end E2 passes through the first rail component 150A. 3 is slidably coupled to the first bracket 110, but in other embodiments not shown, the first connecting end can also be pivotally connected to the second bracket, and the second connecting end can be slidably coupled to First bracket. The second connecting rod 134B has a third connecting end E3 and a fourth connecting end E4. The third connecting end E3 is pivotally connected to the member 124A of the second bracket 120. The fourth connecting end E4 is slidably coupled to the first connecting end E4. The component 114A of the bracket 110. However, in other embodiments not shown, the third connecting end can also be pivotally connected to the first bracket, and the fourth connecting end can be slidably coupled to the second bracket.

In the present embodiment, the length L1 of the first strut 134A is smaller than the length L2 of the second strut 134B. With such an arrangement, when the strut group 130A (130B is also the same as that of the above), the first strut 134A and the second strut 134B are relatively rotated about the pivoting member 136A. The second connecting end E2 and the fourth connecting end E4 are respectively slid in the first bracket 110 and the second bracket 120 due to the aforementioned rotating action, and the first connecting end is limited by the corresponding relationship between the struts and the bracket. The E1 and the third connecting end E3 rotate relative to the first bracket 110 and the second bracket 120 (but do not generate relative movement), and the pivoting member 136A is parallel to the second connecting end E2 and the fourth connecting end E4. The direction is moved, thereby causing the first bracket 110 to move away from the second bracket 120, and the inclination angle θ1 between the first bracket 110 and the second bracket 120 during the movement of the first bracket 110 away from the second bracket 120 , θ2, θ3 (shown in FIG. 5 to FIG. 7, that is, the angle between the first plane P1 and the second plane P2) increases as the distance between the first bracket 110 and the second bracket 120 increases. .

Referring to FIG. 7 , when the first bracket 110 is moved closer to and stacked on the second bracket 120 , the first bracket 110 and the second bracket 120 may be parallel to each other or inclined to each other. In detail, the pivoting member 136A can be pivoted at the middle of the first strut 134A and at the middle of the second strut 134B, that is, at (L1)/2 and (L2)/2, thus, due to the first The struts 134A and the second struts 134B are equally divided into two equal parts by the pivoting member 136A. When the first bracket 110 is moved closer to and stacked on the second bracket 120, the first bracket 110 and the second bracket 120 are Can be parallel to each other. In other words, the position of the pivoting member 136A pivotally connected to the first strut 134A or the second strut 134B is changed such that the pivoting member 136A is offset from the middle of the first strut 134A or the middle of the second strut 134B. When the first bracket 110 is moved closer to and overlapped on the second bracket 120, the first bracket 110 and the second bracket 120 are inclined to each other. Therefore, in the lift table mechanism 100 of the present invention, the position of the table body 200 relative to the user can be changed by changing the position of the pivoting member 136A pivotally connected to the first strut 134A or the second strut 134B. The angle can meet the needs of different user groups, so that users have better ease of use and comfort.

Referring to FIG. 6 and FIG. 7 , the lifting table mechanism includes a use side U1 and a back side U2, and the use side U1 is a side closer to the user when the user uses the lift table mechanism 100, and the first pole is The pivotal joint of the 134A and the first bracket 110 and the pivotal joint of the second strut 134B and the second bracket 120 are located on the use side U1. In the process in which the first bracket 110 moves away from the second bracket 120 (or the process in which the first bracket 110 is lifted upward), when the lift table mechanism 100 is deployed from the state shown in FIG. 7 to the state shown in FIG. 6, The length L2 of the second strut 134B is smaller than the length L1 of the first strut 134A, so that the first strut 110A moves up away from the second bracket 120, and the first strut 134A lifts the first bracket 110 to a smaller extent than the second strut 134A. The strut 134B lifts the amplitude of the first bracket 110, with further reference to FIG. 5, so during the upward lifting of the first bracket 110, the tilt angle θ3 between the first bracket 110 and the second bracket 120 (shown in FIG. 7) ) will gradually increase as the tilt angle θ2 (shown in Figure 6), and then further increase the tilt angle θ1 (shown in Figure 5), and the first bracket 110 will move to the use side U1 away from the back Side U2. In other words, θ1 > θ2 > θ3.

In other words, when the user uses the lifting table mechanism 100, the table body 200 can gradually change the angle as the first bracket 110 is lifted, and the table body 200 can face the user regardless of the lift, and can allow the user to The lift table mechanism 100 is used more conveniently and comfortably. In other embodiments not shown, the length of the first strut may also be greater than the length of the second strut, and the table body can be moved toward the back side.

Figure 8 is a partial front elevational view of the lift table mechanism of Figure 1, taken in a right side view of Figure 1. Please refer to FIG. 3, FIG. 4 and FIG. 8 at the same time. It should be mentioned that the lifting table mechanism 100 further includes a positioning component 144, a dialing member 142 and a positioning component formed by the elastic member 146, as shown in FIG. 3 and FIG. It is shown that the lifting table mechanism 100 has two sets of positioning components respectively disposed on opposite sides of the first bracket 110, and is described later only by one of the positioning components. In this embodiment, the positioning member 144 has a pivoting end 144c, a biasing end 144b, and a plurality of positioning slots 144a between the pivoting end 144c and the biasing end 144b. The pivoting end 144c is pivotally connected to the component 114A of the first bracket 110, and the positioning member 144 is disposed along the component 114A, thereby enabling the plurality of positioning slots 144a to be positioned on the first slider 152A and the carrier 156A of the first slider. Next to the sliding path. The dial member 142 is pivotally disposed on the member 114A of the first bracket 110. As shown in FIG. 3, the member 114A further has a laterally extending pivoting plate structure 114A1. The dial member 142 is substantially pivotally connected to the pivoting plate of the member 114A. In the structure 114A1, the dial member 142 has a protruding rod 142a that movably extends to the biasing end 144b. As shown, the biasing end 144b has a groove profile to allow the protruding rod 142a to extend therein and thereby align the positioning member 144. Further, the dial member 142 is adapted to be driven by an external force such that the lug 142a pushes the biasing end 144b to rotate the positioning member 144 relative to the member 114A of the first bracket 110 by the pivot end 144c.

Referring to FIG. 5 to FIG. 7 , correspondingly, the carrier 156A of the first slider further has a latching flange 156e, which is, for example, a bent structure of the edge of the carrier 156A, and the lifting table mechanism 100 further includes an abutting portion. 148, the component 114A is assembled and the elastic member 146 is received therein, and the biasing end 144b of the positioning member 144 is also accommodated in the abutting portion 148 at the same time. In other words, the elastic member 146 is configured to abut between the abutting portion 148 and the biasing end 144b of the positioning member 144. In this way, the elastic member 146 can drive the positioning member 144 to rotate by its elastic force, that is, the biasing end 144b is changed in position by the driving of the protruding rod 142a and the elastic member 146.

For example, in the state shown in FIG. 5, the user pushes the toggle member 142, and the positioning member 144 is rotated by the curved arrow shown in FIG. 5 to allow the latching flange 156e and the positioning groove 144a to interact with each other. Separating, at this time, the user can apply force (via the first bracket 110) to the strut groups 130A, 130B, for example, applying downward pressure to move the first bracket 110 toward the second bracket 120, as shown in FIG. And the elastic member 146 at this time is also compressed by the force. Then, when the first bracket 110 is moved to the position shown in FIG. 7, the user removes the biasing force on the dial member 142, so that the elastic force of the elastic member 146 drives the positioning member 144 to rotate toward the table body 200. The direction is reset to allow the click flange 156e to be placed in one of the positioning slots 144a. Accordingly, the elastic member 146 of the present embodiment is such that the constant drive positioning member 144 and the click flange 156e are engaged with each other. Here, the arrangement of the positioning groove 144a and its spacing are not limited, and the positioning groove 144a is provided at a desired position depending on the use requirements.

In another embodiment, not shown, the elastic member can also have its constant drive positioning member and the click flange away from each other by the characteristics of tensile deformation.
