The mvention will now be ehucidated by means of a prefored embodiraent as shown in the figurss, where: Figure Ì is a perspective exploded view of an adjustable support am according to the invention; Figure 2 is a side view of the adjustable support arm of figure 1; and | Figures 3 and 4 are transparent side views of the adjustable support arm of figure 1 in two | differently adjusted positions. | According to the figures an adjustable support ann comprises a base bracket 1, an object bracket 2, | a lower link 3 and an upper bok 4, which are mutually mvotally connected by means of bolts, mits | and bearings (not shown) at first pivot point A, second pivot point B, third pivot point © and fourth | pivot point DD, such that they form a parallelogram linkage.
The base bracket 1 may be arranged to | IS be mounted to a wall or to a table desk top, and the object bracket 2 may be arranged to be | connected with a computer display, or for mstance a lamp, desk or other device that needs to be | mounted at an adiusiable height.
By the paraliclogram linkage the object can be moved in the | vertical plane relative to the base bracket while not being rotated relative thereto. | A spring member 5 is attached at one end to the upper Hak 4 near the third pivot point ©, by means | of a pin 51 extending through a hole 42 in the disc shaped bead 41 of the upper link 4 and into the | cad of the spring member 5, where U is fixed to the spring § by means of a bolt SZ, The other end | of the spring member $ is attached to a mounting link 53, which is pivotally attached to ons end of ; a drag link ó by means of a pivot pin 7. The other end of the drag hink 6 1s pivotally attached to the | object bracket at pivot point Th The lower hnk 3 comprises a goide part 31 in which two curved slots 32 extend.
The pivot pin 7 | extends on both sides of the drag link & into the curved slots 32, such that the end of the drag Unk | and the end of the spring member § is forced to follow the path of the curved slat 32. | The slots 32 form circle sections of approximately 20% of a circle (or approximately 36 degrees), and the convex sides of said curved slots 32 face the opper link 4. The first ends of the slots and the à extend near the second pivot point B.
Seen relative to the center Ins between the first pivot point A : and the second mvol point B, the second ends of the slots 32 extend below the first ends of the : 33 slots 32, and furthermore the second ends of the slots extend below said center hing between the | first pivat point A and the second pivot point B.
The tangent Hine of the curved path at end near the 9 pivot point B extends substantially parallel with said center line between the first pivot pont A and the second pivat point B.
The tangent Ene of the curved path al the other end extends at an angle of approximately 44 degrees with said center line between the first pivot point A and the second pivot point B.
The invention has thus been described by means of a preferred embodiment.
