Fig. 1 to Fig. 4 , a multifunctional armrest adjustment member of the present invention includes anarmrest support 10, anouter sleeve 20, apositioning rod 30, apositioning part 40 and anarmrest body 50. Avertical guide slot 11 is disposed on anupper part 101 of thearmrest support 10. Twosymmetrical toothed bars 12 are respectively arranged at each of two corresponding inner surfaces of theguide slot 11. Thetoothed bar 12 has a plurality oftoothed grooves 121 arranged from top to bottom. Alower part 102 of thearmrest support 10 is connected to a left side or right side of a seat (not show in figure). - The
outer sleeve 20 is disposed around an outer surface of theupper part 101 of thearmrest support 10 with proper allowance. An opening 21 is arranged at a side surface of theouter sleeve 20 for mounting abutton 60 having a fasteningpart 61. Atop plate 22 with apost 221 is covered on theouter sleeve 20. Twocorresponding limit slots 23 are mounted on an inner wall of a top end of theouter sleeve 20. - The
positioning rod 30 is a T-shaped bar pivoted in theouter sleeve 20. The top two ends of the T-shaped bar are corresponding to and pivoted in thelimit slots 23 of theouter sleeve 20. Thepositioning rod 30 includes a lockingpart 31 on a bottom end thereof. The lockingpart 31 is corresponding to the two symmetricaltoothed bars 12 on theguide slot 11 of thearmrest support 10 and is locked into one of thetoothed grooves 121 of thetoothed bar 12. Twobumps 32 are arranged at a middle part of thepositioning rod 30. Thebump 32 is corresponding to and fastened to thefastening part 61 of thebutton 60. When thebutton 60 is pressed, thepositioning rod 30 is driven to move around the top end (as a pivot shaft) thereof. Thus the lockingpart 31 is released from thetoothed groove 121 of thetoothed bar 12 and thepositioning rod 30 is able to be moved up and down in relation to thearmrest support 10 along with theouter sleeve 20. Moreover, position holes 33 for mounting anelastic part 70 are disposed over the lockingpart 31 of thepositioning rod 30. Apost 34 is arranged at thepositioning rod 30. Thepost 34 is corresponding to theelastic part 70 and used for limiting movement of theelastic part 70. - The
positioning part 40 is disposed above theouter sleeve 20. Thepositioning part 40 includes two symmetrical projectingcurved parts 41 at the middle part thereof, aninsertion hole 42 at a center between the two projectingcurved parts 41, afastener 43 such as a locking screw passing through theinsertion hole 42 to be fastened on thepost 221 of thetop plate 22 of theouter sleeve 20, and twobumps 44. - The
armrest body 50 is disposed on top of theouter sleeve 20. Thearmrest body 50 includes anarmrest pad 51 and anarmrest base 52. Twopivot parts 53, pivoted and connected to each other, are respectively arranged at the middle part of both thearmrest pad 51, and thearmrest base 52 correspondingly. Agroove 54 is disposed at an axis in the forward and backward direction of thearmrest body 50. Thepost 221 on thetop plate 22 of theouter sleeve 20 passes through thegroove 54 to be fastened to thepositioning part 40 by thefastener 43. Thus thepositioning part 40 is moveably mounted between thearmrest pad 51 and thearmrest base 52. Thearmrest base 52 further includes twocurve areas 55 on an inner surface thereof corresponding to two projectingcurved parts 41 of thepositioning part 40. Thus thecurve area 55 can be rotated in relation to thecurved part 41. Moreover, at least oneelastic part 57 such as a spring is arranged at one end (the front end or the rear end) of both thearmrest pad 51 and thearmrest base 52. Furthermore, the shape and the structure of thepositioning rod 30, thepositioning part 40 and thearmrest body 50 are symmetrical designs, such as fore-and-aft symmetry or mirror symmetry. Due to symmetry, there is no limit while assembling theses parts. They can be switched from left to right side (or right to left side), from fore to aft, or vice versa. This helps assembly operation and materials management. In addition, the number of the components required is reduced. - Refer to
Fig. 3 ,Fig. 4 , andFig. 5 , thepositioning part 40 and thearmrest base 52 are respectively arranged with thebump 44 and agrid groove 56. Thebump 44 is corresponding to thegrid groove 56 and is able to slide forward and backward in thegrid groove 56, as an arrow A indicated inFig. 5 . Or thebump 44 is rotated in thegrid groove 56, as an arrow B indicated inFig. 6 . Moreover, the moved position and the position of thebump 44 are controllable. Refer toFig. 3 , the number of thebumps 44 is two. Thebumps 44 are respectively disposed on the front end and the rear end of the bottom surface of thepositioning part 40. As shown inFig. 3 andFig. 5 , thegrid groove 56 includes linear lines in a fore-and-aft direction (the arrow A inFig. 5 ) and curved lines in a left-and-right direction (the arrow B inFig. 6 ). Thebump 44 is disposed on the bottom surface of thepositioning part 40 so as to contact against thegrid groove 56 of thearmrest base 52 elastically and there is friction resistance existed between the positioningpart 40 andgrid groove 56. Thus the stability of the assembly and the smoothness of movement are improved. - Refer to an arrow C in
Fig. 4 , while applying pressure to the front end or rear end of thearmrest pad 51, thearmrest pad 51 is moved up and down in relation to thearmrest base 52 like a seesaw and thepivot parts 53 act as the fulcrum (pivot shaft). By elasticity of theelastic part 57, thearmrest pad 51 is turned back to the original position after being released from the pressure applied. - Refer to
Fig. 4 andFig. 5 , while operating thearmrest body 50 to move forward/backward in relation to thepositioning part 40, as the arrow A indicated inFig. 5 , thepositioning part 40 remains static and thebump 44 on the bottom of thepositioning part 40 is against thegrid groove 56 of thearmrest base 52 while thegroove 54 of thearmrest body 50 moves forward/backward along thepost 221 on thetop plate 22 of theouter sleeve 20. - Refer to
Fig. 4 andFig. 6 , while operating thearmrest body 50 to rotate in relation to thepositioning part 40, as the arrow B indicated inFig. 6 , thepositioning part 40 remains static and thecurved part 41 of thepositioning part 40 rotates within thecurve area 55 of thearmrest base 52. At the same time, thebump 44 on the bottom of thepositioning part 40 also rotates along thegrid groove 56 of thearmrest base 52. - Refer to
Fig.7A and Fig.7B , they respectively show thearmrest body 50 before and after the upward movement. While pressing thebutton 60, as an arrow D indicated in theFig. 7B , thebutton 60 drives thepositioning rod 30 to rotate around the top end of the positioning rod 30 (two ends of the T-shaped bar). Thus the lockingpart 31 of thepositioning rod 30 is released from onetoothed groove 121 of thetoothed bar 12 and now theelastic part 70 is compressed. Then thearmrest body 50 is moved upward to the desired height, as an arrow E indicated in theFig. 7B . Theouter sleeve 20 is moved upward by thepositioning part 40 of thearmrest body 50 and thepositioning rod 30 is also moved upward along with theouter sleeve 20. When thebutton 60 is released, thepositioning rod 30 is turned back to the original position by elastic recovery force of theelastic part 70. And the lockingpart 31 of thepositioning rod 30 is locked into anothertoothed groove 121 of thetoothed bar 12. The height adjustment of thearmrest body 50 is completed. Thearmrest body 50 can also be adjusted to move downward in the same way. - In summary, the armrest adjustment member of the present invention can adjust horizontal and vertical movement, rotation and up and down movement (like a seesaw) of the
armrest body 50, having multiple functions. While adjusting the forward and backward movement of thearmrest body 50, the rotation of thearmrest body 50 can also be adjusted at the same time. Moreover, due to simple structure and fewer components, the manufacturing cost is reduced. Furthermore, the assembly cost is down because of easy assembling. - Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
