In the description of the present invention, the term "at least one" means one or more unless explicitly defined otherwise. The term "inward" refers to the armrest moving in a direction closer to the centerline of the seating furniture, and the term "outward" refers to the armrest moving in a direction away from the centerline of the seating furniture.

The specific implementation manner of the utility model is as follows:

example (b): as shown in fig. 1 to 13, the present invention provides a handrail, which comprises a handrail main body 1 arranged vertically, a supporting member arranged substantially horizontally and a handrail supporting plate 3 also arranged substantially horizontally; in the embodiment, the support member is a swing arm 2, one end of the swing arm 2 is rotatably connected to the upper end of the armrest body 1, and the swing arm 2 is configured to have a smaller rotation angle range, specifically 0 to 45 degrees, with respect to the armrest body 1; any end of the armrest support plate 3 is rotatably connected to the other end of the swing arm 2, and the armrest support plate 3 is disposed in a large rotation angle range, specifically 0 to 325 degrees, with respect to the swing arm 2.

As shown in fig. 2 and 3, the arrangement of the swing arm 2 in a small rotation angle range section with respect to the armrest body 1 means: an installation groove 4 is arranged at the end of the swing arm 2 rotatably connected with the handrail main body 1, a swing arm fixing cover 5 is arranged in the installation groove 4, and a rotation limiting mechanism is arranged between the swing arm fixing cover 5 and the swing arm 2; the rotation limiting mechanism comprises two arc-shaped lugs 6 which are symmetrically arranged and two symmetrical arc-shaped limiting grooves 7, and the radian of each arc-shaped limiting groove 7 is greater than that of each arc-shaped lug 6; wherein arc lug 6 sets up on rocking arm 2, and be located 4 lower extreme both sides of mounting groove, protrusion in 4 lower extremes of mounting groove, be less than the 4 upper ends of mounting groove, arc spacing groove 7 sets up on rocking arm fixed cover 5's bottom surface, when rocking arm fixed cover 5 downwards lock is in mounting groove 4, arc lug 6 corresponds and plants in arc spacing groove 7, at this moment, will rock the center department of arm fixed cover 5 and fixed continuous with handrail main part 1 upper end through the screw, realize rocking arm fixed cover 5 circumference and axial fixity. As shown in fig. 4, in the present embodiment, the swing arm fixing cover 5 is covered with a decorative cover 17 to conceal screws for the sake of appearance.

Arc lug 6 along circumferencial direction's size and radian can set up in advance, likewise, the radian size of arc spacing groove 7 also can adjust in real time as required, when needs turned angle is big, can set up arc lug 6 radian a little, sets up arc spacing groove 7 radian a little more, and the rotation that just corresponds rocking arm 2 through adjusting arc lug 6 in arc spacing groove 7 is empty promptly.

As shown in fig. 1 and 4, the arrangement of the armrest support plate 3 with respect to the swing arm 2 in a large rotation angle range section means: a boss 8 is arranged at the other end of the swing arm 2, the boss 8 is configured as a rotating shaft of the handrail support plate 3, and the handrail support plate 3 is sleeved on the boss 8 through an assembling hole 9 arranged at the end part of the handrail support plate; the upper end of the boss 8 in the assembling hole 9 is also provided with a handrail supporting plate fixing cover 10, the handrail supporting plate fixing cover 10 is fixedly connected with the boss 8 through a screw, and the handrail supporting plate 3 is clamped between the handrail supporting plate and the boss 8 in the axial direction; the assembling hole 9 is tapered with a large upper part and a small lower part, so that the handrail supporting plate fixing cover 10 forms a limit for the handrail supporting plate 3.

Still including rotating the rotatory stop gear of restriction to handrail backup pad 3, rotatory stop gear include stop buckle 11, stop buckle 11 has two installation ears 12 of bilateral symmetry, installation ear 12 passes through the screw fixation in the other sunken holding tank 13 of pilot hole 9, stop buckle 11 upper end has a convex stopper 14 of horizontal direction, stopper 14 passes through on the pilot hole 9 lateral wall predetermined breach 15 and gets into in the pilot hole 9, is equipped with along the not through annular groove 16 that contracts in the radial direction in handrail backup pad fixed cover 10 up end periphery, stopper 14 head is in annular groove 16.

The radian of the annular groove 16 along the circumferential direction determines the rotation angle of the armrest support plate 3, and when the head of the limiting block 14 is abutted against the edge of the annular groove 16 along the circumferential direction, the armrest support plate 3 is limited to continue rotating; the rotation limiting mechanism is more convenient to install, when in installation, the handrail support plate 3 can be sleeved on the boss 8, and the handrail support plate fixing cover 10 is installed; then installing a limit buckle 11; if the limit buckle 11 is not installed, the handrail support plate 3 can rotate by 360 degrees; therefore, the stop buckle 11 can be installed or not installed according to the needs of users.

As shown in fig. 6 and 7, the initial state diagram of the armrest is defined in the present embodiment, in which the armrest is perpendicular to the seat back, and neither the swing arm 2 nor the armrest support plate 3 rotates; as shown in fig. 8 and 9, the swing arm 2 and the handrail support plate 3 are both rotated inward; as shown in fig. 10 and 11, the swing arm 2 is rotated outward, but the handrail support plate 3 is not rotated, as can be easily seen from comparing fig. 6 and 7, the handrail support plate 3 is moved outward by a certain distance by the swing arm 2.

As shown in fig. 12, which is a top view of the two armrests in the same position when the user is seated, the swing arm 2 is rotated inward so that the armrest support plate 3 is translated inward by a distance, specifically, the armrest support plate 3 is translated from the position a to the position b in fig. 12; as shown in fig. 13, which is a top view of the two armrests in different states when the user sits on, the armrest indicated by c in the figure is rotated inward by a small angle, specifically, the armrest support plate 3 is rotated inward, while the swing arm 2 is not rotated, so that the armrest is rotated by a small angle as a whole; the handrail indicated by d in the figure is turned inward by a large angle, and specifically, the handrail support plate 3 and the swing arm 2 are both turned inward by a certain angle, so that the handrail as a whole is turned by a large angle.
