Referring to Fig. 1, numeral 10 indicates a chair including a center pillar 12, and an upper end of the center pillar 12 supports a base 14. The base 14 supports a base 16 and a backrest 18. The backrest 18 includes, for example, a supporting structure formed by two arms 20 (only one is shown in FIG. 1), and the front ends of the two arms 20 are connected to the base 14. According to the present invention, the chair 10 includes an armrest assembly 22 on each side. Referring to Figures 2 and 3, the armrest assembly 22 includes a support arm 24 that can extend in the longitudinal direction. The rear part of the support arm 24 is articulated to the support of the seat back, and the front part supports a health-supporting hump member 26. The support arm 24 can be moved between a fully raised position shown in FIG. 2 and a fully lowered position shown in FIG. 3. In Figure 1, the two positions of Fufeng & 1 Λ, Happy, and Piece 22 are indicated by continuous and dashed lines, respectively. The armrest assembly may have a plurality of intermediate positions between two positions of the armrest cymbals shown in FIG. I. The armrest member 26 is attached to the front end of the support arm 24 and is movable in the vertical direction. The connection method between the armrest # 26 and the support arm 24 is to keep the armrest member 26 in a position parallel to itself while moving the armrest member 26 in the vertical direction. Referring to Figures 2 and 3, the support arm 24 includes a parallelogram mechanism 28 articulated, including a first rod 30 and a second rod 32. The rods 30 and W have first ends 34, 36, respectively, and support structures that are articulated to the backrest 20 at first and second parallel axes 38, 40, respectively. The joint axis 38 of the first lever 30 is replaced downward with the relative position of the joint axis 40 of the second lever 32. As shown in FIG. 4, the support structure of the seat back 20 has a joint connection area 42 having two holes 44 and 46, and the center of the hole is connected with two pivots 48 and 50. Two pivots 48, 50 are fixed to the ends 34, 36 of the rods 30, 32, respectively. From a structural point of view, each of the rods 30 and 32 is formed of two metal rods having a flat rectangular cross-section fixed to each other 'as shown in Figs. 52 and 54 and 56 and 58 of Figs. Referring to FIGS. 2, 3 and 4, the joint connection region 42 of the support structure of the seat back 20 supports a fixing bracket 60 which can seal the ends 34 and 36 of the rods 30 and 32. The fixing sheath 60 passes through a screw 66. The two shells 62 and 64 are preferably fixed to the Guanlang connection area 42 and formed. The fixed sheath 60 has a side opening 68 through which the rods 30 and 32 can be extended. 5 200417345 Referring to Figures 2, 3, and 6, the rods 3 3 2 each have central portions that overlap each other at least partially in the direction of the transverse pivot (that is, the direction orthogonal to the plane shown in Figures 2 and 3). The central portions of the rods 30, 32 are enclosed in a sheath 70 that can move with the limbs. As shown in FIG. 6, it is preferable that the sheath 70 is formed of two shells 72 and 74 fixed to each other. For example, the element connection method is snap 〇π, which is schematically illustrated by 76 in FIGS. 2 and 3. . Referring to Figures 2, 3 and 7, the armrest member 26 includes a base plate 78 which supports a pair of downwardly projecting flanges 80. The flange 80 has two pairs of holes which are respectively connected to two pivots 82 and 83 which determine the position of the joint axis 8 and 85 respectively. As shown in Figs. 2, 3, 6 and 7, the rods 30, 32 respectively have a second end 84,% which is articulated to the flange 80 of the base plate 78 via pivots 82, 83, respectively. The joint is fortunately aligned with the heart 85 and the first end 34, the joint axis ^ of the first joint 34, and the joint axis 81 of the 30th joint, and the relative position of the joint axis 85 of the second rod 32 is changed. Replace it. This device includes a parallelogram mechanism formed by the above-mentioned joint axes 38, 40 and the rods U, U, and 32, which are connected in an articulated manner (2 ~ the pendulum 32 will follow the fixed joint axes 38, 4). The relative position is vertical. The straight lines connecting the joint axes 81 and 85 are kept parallel to the straight lines connecting the joints ^ ^ f. This can ensure that when the armrest member 26 moves in the vertical direction, θ ^ shire will remain parallel to itself. The combination of the ends 84, 86 of the levers 30, 32 > ^ σ A locking mechanism 88 can be locked at the active position selected by the user, without the arm 24. From a conceptual point of view, the locking mechanism 88 is at The two poles 30 and 32 are inserted ^ ^ There is a safety element between Anmei, Anwang components have the function of ensuring that the two poles 30 and 32 are in the pre-lock position 6 200417345. Each locked position corresponds to the support Arm 24 —Angle position. The locking mechanism 88 can be temporarily unlocked to allow the user to change the angular position of the support arm. Therefore, the armrest member 26 is kept in a vertical position. A better specific example of the locking mechanism is No. 2, 3, 6 and Figure 8-10. Locking mechanism 8 8 Contains a security element 90 composed of a sturdy element such as metal or plastic. The security element 90 has a joint portion 92 with a hole 94, a link handle 96, and a cylindrical head 98 at the opposite end of the joint portion 92 The safety element 90 cooperates with a locking element 100, which includes two pliers elements 102 and 104 connected to each other in a joint via a pivot 106. The first pliers element 102 has a leading part 1 〇8, the leading part 108 has a smooth wall hole with the same radius or larger than the outer diameter of the link part 96. The second sweetener element 104 has a starting part 112 and a fixed part 11 having a ring-shaped surface. The fixed portion 114 has a link surface, the shape of which corresponds to the external shape of the link portion. A compression spring 116 is placed between the two pliers elements 1 0 2 and 1 04 to help push the fixed portion 114 to the safety element 9 The link part of 〇. Figure 1 shows the close part of the two pliers element 1 〇2, 〇 04. These two pliers elements can manually start the part 11 by, for example, releasing the link part 96 from the fixed part 114. Open. As shown in Figures 10 and 11, attachment 11 18, two pivot-shaped attachments 11 8 rows of joint axis 1 2 0.

When the fixed part 114 is engaged with the link part 96, the security element 90 can move relative to the locking member 100 in the direction indicated by the arrow 22 in FIG. 8, and at the same time, 'the security element 90 and the locking member can be avoided. There are relative movements in opposite directions. Referring to Figures 2 and 3, the locking mechanism 88 connects the end portions 84, 86 of the rods 30, 32 in an articulated manner. The head 92 of the safety element 90 is articulated to the second rod 32. The same pivot shaft 83 is extended through the hole 94 to connect the distal end portion 86 of the first rod 32 in an articulated manner, and it is preferable to connect the security element 90 in an articulated manner at the axial center 85. The pivot-shaped portion us of the locking member 88 is jointed with the respective holes 1 2 4 in the fork-shaped attachment 1 2 6. The fork-shaped attachment 1 2 6 is contained in the end portion 8 4 of the first rod 30. The end portions 84, 86 and locking mechanism 88 of the rods 30, 32 are enclosed in a sheath 128, which is connected to the attachment 134 of the sheath 70 by the two shells 13 and 132 via snap-fit engaging elements (138, 140) (Fig. 6) , 136 formed better. As shown in Figures 2 and 3, the sheath 12 8 has an opening 142 through which the arms 30, 32 are extended. The shell 130 of the sheath 128 has a side face hole 1 44 at the activation position 1 1 2 of the lock mechanism 88. An elastic membrane 1 46 is fixed to the sheath 1 2 8 at the hole 1 44. 2 and 3, the armrest member 26 includes an armrest body 150 and an intermediate support member 152. The intermediate support member 152 is slidably (relative to the base plate 78) mounted on the base plate 78, and the base plate 78 supports the joint pivots 8 1 and 85 in the direction indicated by the arrow 154. The middle supporting element 1 5 2 supports a screw 1 5 5 ′ and a screw 15 5 determines a joint at a position where it is connected to the armrest main body 150 by a joint 200417345 vertical axis 1 5 6 position. 78 rotates in the longitudinal direction (arrow 154 1 56). The armrest body 150 has the function of adjusting the position with respect to the base plate. In addition, the armrest body can be adjusted at the axis 156 and the longitudinal direction. Can be considered selective. In the simplistic type, you can eliminate single- or both-side adjustments. In the simplest type, the armrest main body 150 can be connected to the base plate 78 and fixed on the base plate 78. In this example, Fu + 150 has the function of adjusting height alone. The armrest 15 can also have other kinds of adjustment actions relative to the base plate 78: for example, lateral adjustment can be performed by sliding the armrest body 15o in a position relative to the intermediate support element 152 or relative to the base plate 78 in the lateral direction. . As described above, the 'locking mechanism 88' is preferably used to complete a single item lock by this method. To move the armrest upward from the lowest position shown in Figure 3, the user just needs to raise the armrest to the desired vertical position. To lower the armrest, press the activation portion 112 located behind the deformable membrane 156 to release the lock mechanism 88, and then lower the armrest to the desired position. When the pressure applied to the starting position 112 is released, the locking mechanism 88 will lock the arm 24 in the new position.
