New description: [New technical field] This creation department is about a stepless lifting handrail structure, especially an innovative structure that can effectively improve the convenience of the handrail in lifting height adjustment. [Prior Art] Press, whether it is at home or office, the chair is an indispensable tool. Generally, the chair considers the user's long ride, except that the seat and the back of the chair are ergonomically designed to have a certain curvature. The shape allows the user to have a feeling of pain and discomfort after sitting for a long time. In order to allow the user to comfortably place the hand when riding the chair, the handrail is designed and the handrail can be Depending on the height of the occupant, the height adjustment is adjusted. The design of the lifting structure is as follows: Announcement No. 585059 "Additional (1) of the lifting mechanism of the seat armrest (backrest)" The corresponding part is sleeved on the outer periphery of the main support pipe frame, and two pairs of half of the lifting guide groove seat body are assembled in the main support pipe frame, and the phase critical layer formed by the two lifting guide seat block bodies is formed. The space 疋 can be accommodated by the raking member, and the hole is formed along the lower section of the tying member to smoothly fit the weight portion of the vertical group with the limit rod portion and the limit hook portion of the vertical erection top The segment is in constant contact with the boundary of the corresponding guiding groove of the corresponding lifting guide seat, and the other side of the boundary guiding groove recessed by the lifting guiding seat is a surrounding groove extending to connect with each other, followed by The corresponding level of the lifting guide seat on which the back side of the 掣 part abuts forms an elastic top contact portion which can make better contact with each other; the hoisting and lowering body according to the above is positioned with the corresponding shaped handrail, and can be borrowed The 5 M308021 step drive of the handrail can make the hook section of the handrail according to the corresponding limit guide groove. It is according to the lifting guide groove and has many notches=limit=section, which is in the setting form. The plucking section of each of the slanting guiding sections of the plunging guiding section is provided with a restriction portion, and the allowable limit of the plucking guiding section is γ:: γ Smoothly travel in between; make the position ^ position operation. The orientation adjustment of the entrance and exit is convenient to control. The above-mentioned structural design can be seen that the 'finance' pavement handrail (additional backrest mechanism (1)) is used in the actual implementation, and the following is missing: 2: 2 handrails (backrest) Adding (1)" to the lifting mechanism is a number of notches (4) limit guide grooves made by the seat, and the lifting height of the handrail (backrest) is matched with the fishing section of the limit hook, so the height of the handrail (backrest) can be raised and lowered. The adjustment is limited by the position of the limit guide t-card ▲ 掣, according to the stage structure design, often the U back) adjusted height, there is no way to meet the user's needs 2 = 虞, resulting in The discomfort of the user's hand placed on the armrest is reduced. The lifting mechanism of the armrest (backrest) of the chair is added (1). It can only be adjusted for the degree of elevation when the user feels the height of the adjustment. When the user feels that the height of the adjustment is not enough: when the comfort is f: at this time, the boundary must be hooked The bottom of the rod: the hook is lowered to the highest point of the guide groove, and then the bottom of the groove is connected to the lower point of the guide groove to re-adjust the ancient degree. Here, the inconvenience caused by the use of the 6 M308021 edge, the creator in view of the lack of structural materials on the existing handrail lifting, is to rely on the __ manufacturing and design of the new and knowledge of the assistance, and through the multi-party I thought about creating a new version of the handrail lifting structure. Also [new content] This creation department has a kind of paragraph-free lifting handrail structure, which is convenient for the height adjustment of the ancient handrails. It is fixed in the seat of the seat chair: the base of the handrail is connected to the base of the handrail. There is a & extension rod, and the extension group is provided with a rack, and the armrest body is sleeved in the extension rod, and a gear for correspondingly engaging with the rack is disposed on the armrest body, and the gear is further A braking block is arranged on the upper side, and the braking part of the braking block is provided with a tooth portion for interengaging with the gear, and an action portion is connected to the upper end of the rod body connected with the braking block; thereby designing a 'system of pulling action' When the interlocking brake block is displaced, the tooth portion is disengaged from the gear meshing state, and after the gear is disengaged from the brake block, the reciprocating motion can be performed on the rack, thereby facilitating the adjustment of the armature to the south. Benefits. ° [Embodiment] In order to make the technical content, creative purpose and the effect achieved by this creation more complete and clear, please elaborate below, and please refer to the drawings and drawings : ^ First, please refer to the first figure, which is a three-dimensional exploded view of the structure of the paragraphless lifting handrail for this creation. Please also refer to the partial enlarged exploded view of the second figure and the three-dimensional combination of the third figure. The main body is provided with a handrail base (1) fixed to the seat of the seat chair, and an extension rod (2) is fixed to the armrest base (丨), and a rack is arranged in the extension rod (2). (21), another armature body (3) is sleeved in the extension rod (2), and the armrest body (3) is provided with a shell (4) for covering the armrest body (3) with M308021, and The shell (4) can be placed on the outside of the extension rod (2), and the bottom end of the shell (4) is correspondingly connected with the armrest base (1), and is also pivoted to the armrest body (3). There is a gear (31) for spraying corresponding to the rack (21), and a brake block (32) is disposed above the gear (31), and the brake block (32) The gear is provided with a tooth portion (321) for interengaging with the gear (31), and an elastic member (33) is sleeved on the rod body (322) of the brake block (32) to make the The elastic member (33) is disposed at a level (323) of the brake block (32) and the rod body (322), and the other end of the elastic member (33) is disposed on the armrest body (3). The class edge (34) [please refer to the fourth and fifth figures together], and the upper end of the rod (322) connected to the brake block (32) is connected to an action portion (324), and The action portion (324) protrudes from the housing (4) with a slot (41). Accordingly, when using the device, please refer to the fifth and sixth figures, and pull up the action portion (324) to shift the brake block (32) connected to the action portion (324) upwards. The tooth portion (321) is disengaged from the gear (31), and the 'elastic member (33) is restrained by the two-stage edges (323), (34); thereby, in the gear ( 31) After the brake is released from the brake block (32), it can be reciprocated on the meshing rack (21) provided by the extension rod (2) to lift the armrest body (3) to adjust to the user's hand. The south is comfortably placed. When the armrest body (3) is adjusted to the required height, the shackle of the action portion (324) can be released. At this time, the brake block (32) is restored by the elastic force of the elastic member (33). The position is further engaged with the gear (31) to stop the movement of the gear (31), thereby achieving the effect of fixing the height of the handrail after adjustment. According to the above structure and implementation, the author has the following excellent 8 M308021 points:
