FIG. 5 toFIG. 7 are schematic views illustrating state changes of the lifting mechanism for desk, wherein thelever assembly 130A is illustrated with a viewing angle of a right-side view ofFIG. 1 . Meanwhile, thelever assembly 130B on the other side also actuates in the same manner; therefore, no repetition is provided herein. Thepart 114A of thefirst bracket 110 is illustrated in a perspective view (i.e. outlined with dotted-lines) so as to clearly show the relation of the members at the position. In the embodiment, abeam 132 is horizontally connected between thefirst lever 134A and thefirst lever 134C, such that the twolever assemblies FIG. 5 toFIG. 7 first for the descriptions of the actuating mode of thelever assembly 130A. - The
first lever 134A includes a first connecting end E1 and a second connecting end E2 opposite to each other. The first connecting end E1 is pivoted to thepart 114A of thefirst bracket 110, and the second connecting end E2 is slidably coupled to thefirst bracket 110 through thefirst rail assembly 150A (shown inFIG. 3 ).

Meanwhile, the first connecting end E1 and third connecting end E3 rotate with respect to thefirst bracket 110 and the second bracket 120 (without generating relative movement). The pivotingmember 136A moves in a direction parallel to the second connecting end E2 and the fourth connecting end E4, causing thefirst bracket 110 to move away from thesecond bracket 120. Moreover, when thefirst bracket 110 moves away from thesecond bracket 120, as a distance between thefirst bracket 110 and thesecond bracket 120 increases, tilt angles θ1, θ2, or θ3 (illustrated inFIG. 5 toFIG. 7 , that is, an included angle between the first plane P1 and the second plane P2) between thefirst bracket 110 and thesecond bracket 120 increases as well. - With reference to
FIG. 7 , when thefirst bracket 110 moves close to and overlaps thesecond bracket 120, thefirst bracket 110 may be parallel to or may be tilted relative to thesecond bracket 120. To be specific, the pivotingmember 136A may be pivoted at a middle position of thefirst lever 134A and a middle position of thesecond lever 134B, that is, the pivotingmember 136A keeps a distance, (L1)/2, from the first connecting end E1 (or the second connecting end E2), and the pivotingmember 136A also keeps a distance, (L2)/2, from the third connecting end E3 (or the fourth connecting end E4). In this way, since each of thefirst lever 134A and thesecond lever 134B is divided into two equal parts by the pivotingmember 136A, when thefirst bracket 110 moves close to and overlaps thesecond bracket 120, thefirst bracket 110 and thesecond bracket 120 are parallel to each other. In other words, by changing a position where the pivotingmember 136A is pivoted on thefirst lever 134A or thesecond lever 134B, the pivotingmember 136A is made to deviate from the middle position of thefirst lever 134A or the middle position of thesecond lever 134B. As such, when thefirst bracket 110 moves close to and overlaps thesecond bracket 120, thefirst bracket 110 is tilted relative to thesecond bracket 120. Accordingly, in the lifting mechanism fordesk 100 provided by the invention, by changing the position where the pivotingmember 136A is pivoted on thefirst lever 134A or thesecond lever 134B, the angle of thedesk body 200 relative to the user is changed, so as to satisfy needs from different user groups and allow users to enjoy a more convenient and comfortable using experience. - With reference to
FIG. 6 andFIG. 7 , the lifting mechanism for desk includes a user side U1 and a back side U2. The user side U1 is one side of the lifting mechanism fordesk 100 close to the user when the user actually uses the lifting mechanism for desk. A position where thefirst lever 134A is pivoted to thefirst bracket 110 and a position where thesecond lever 134B is pivoted to thesecond bracket 120 are both located at the user side U1. In a process during which thefirst bracket 110 moves away from the second bracket 120 (or a process during which thefirst bracket 110 ascends upwards), when the lifting mechanism fordesk 100 is unfolded from a state shown inFIG. 7 to a state shown inFIG. 6 , since the length L2 of thesecond lever 134B is less than the length L1 of thefirst lever 134A, an extent to which thefirst bracket 110 is lifted up by thefirst lever 134A is less than an extent to which thefirst bracket 110 is lifted up by thesecond lever 134B when thefirst bracket 110 moves away from thesecond bracket 120. With reference toFIG. 5 , when thefirst bracket 110 ascends upwards, the tilt angle between thefirst bracket 110 and thesecond bracket 120 gradually increases from the tilt angle θ3 (shown inFIG. 7 ) to the tilt angle θ2 (shown inFIG. 6 ) and then further increases to the tilt angle θ1 (shown inFIG. 5 ). Further, thefirst bracket 110 moves towards the user side U1 away from the back side U2. In other words, θ1>θ2>θ3. - In other words, when the user uses the lifting mechanism for
desk 100, the angle of thedesk body 200 may gradually change as thefirst bracket 110 is lifted up. Further, regardless of the heights of lifting, thedesk body 200 can face the user. In this way, the user may use the lifting mechanism fordesk 100 more conveniently and comfortably. In other embodiments that are not shown, the length of the first lever may be greater than the length of the second lever, and the desk body may move towards the back side. -
FIG. 8 is a portion of the lifting mechanism for desk ofFIG. 1 , which is illustrated with a viewing angle of a right-side view ofFIG. 1 . Referring toFIG. 3 ,FIG. 4 , andFIG. 8 together, it should be pointed out that the lifting mechanism fordesk 100 further includes a positioning assembly consisting of apositioning member 144, a stirringmember 142, and anelastic member 146. As shown inFIG. 3 andFIG. 4 , the lifting mechanism fordesk 100 includes two sets of positioning assemblies respectively disposed at the opposite sides of thefirst bracket 110. The following embodiment is described with only one set of the positioning assembly. In the embodiment, the positioningmember 144 includes a pivotingend 144 c, a forcingend 144 b, and a plurality ofpositioning slots 144 a located between the pivotingend 144 c and the forcingend 144 b. The pivotingend 144 c is pivoted to thepart 114A of thefirst bracket 110, and thepositioning member 144 is disposed along thepart 114A. As such, the positioningslots 144 a are all located next to a sliding path of the first slider 152A and thecarrier 156A of the first sliding member. The stirringmember 142 is pivoted to thepart 114A of thefirst bracket 110. - As shown in
FIG. 3 , thepart 114A further includes a pivoting plate structure 114A1 extending laterally. The stirringmember 142 is substantially pivoted in the pivoting plate structure 114A1 of thepart 114A, and the stirringmember 142 includes a protrudingrod 142 a that movably extends to the forcingend 144 b. As the drawing shows, the forcingend 144 b is formed with a recessed profile such that the protrudingrod 142 a can insert in and accordingly stir thepositioning member 144. More specifically, the stirringmember 142 is adaptable to be driven by an external force such that the protrudingrod 142 a can push the forcingend 144 b, so that thepositioning member 144 rotates with respect to the part 144A of thefirst bracket 110 via the pivotingend 144 c. - With reference to
FIG. 5 toFIG. 7 , correspondingly, thecarrier 156A of the first sliding member further includes an engagingflange 156 e, which, for example, is a bending structure of an edge of thecarrier 156A. Also, the lifting mechanism fordesk 100 further includes anabutting part 148 assembled in thepart 114A to accommodate theelastic member 146. The forcingend 144 b of thepositioning member 144 is also accommodated in theabutting part 148. In other words, theelastic member 146 is disposed to be abutted between theabutting part 148 and the forcingend 144 b of thepositioning member 144. With such configuration, theelastic member 146 can drive the positioningmember 144 to rotate via an elastic force; that is, the forcingend 144 b is driven by the protrudingrod 142 a andelastic member 146 to change its position. - For instance, in the state shown in
FIG. 5 , the user applies a force to the stirringmember 142 such that thepositioning member 144 rotates in the manner as shown by the arc-shaped arrow inFIG. 5 , so that the engagingflange 156 e is separated from thepositioning slot 144 a. At this time, the user can apply another force (via the first bracket 110) to thelever assemblies first bracket 110 moves close to thesecond bracket 120. AsFIG. 6 shows, theelastic member 146 is also compressed by the force. Next, when thefirst bracket 110 moves to the position shown inFIG. 7 , the user removes the force applied to the stirringmember 142. Hence, the elastic force of theelastic member 146 drives thepositioning member 144 to rotate to be restored towards a direction of thedesk body 200, such that the engagingflange 156 e is engaged in one of thepositioning slots 144 a. Accordingly, theelastic member 146 in the embodiment constantly drives thepositioning member 144 to be engaged with the engagingflange 156 e. The invention provides no limitation to the configuration and distance of thepositioning slots 144 a; thepositioning slots 144 a are provided where necessary depending on the need. - In another embodiment that is not shown, the elastic member can constantly drive the positioning member and the engaging flange to be away from each other via the stretching and deforming characteristics.
