The movable shell and the oblique straight rod are arranged at an oblique included angle, so that the movable shell moves obliquely, thereby achieving the bi-directional adjustment of vertical height and longitudinal position; and the lift adjusting assembly has simple structure and convenient operation, and in addition, the utility model also has the advantages of low manufacturing cost and easy installation and maintenance.
Description
Technical field
The utility model relates to daily daily necessities field, is specifically related to a kind of handrail of seat.
Background technology
The individual chair of family expenses or office usefulness can be provided with pair of armrests usually, and handrail can give both arms and support when the user loosens, and in addition, handrail can give certain support force to reduce the pressure to the chair back when user's reclining.
The handrail height of existing most seats is fixed, and handrail height is determined according to ordinary person's average height build during design, is difficult to satisfy different users's comfort level demand.In order to overcome above-mentioned defective, adjustable for height handrail has also appearred, for example China No. 97227980.6 patent disclosures a kind of liftable armrest, but this liftable armrest can only be regulated on the single ground vertical height, and in fact need its forearm of people that handrail height is heightened also longer, iff heighten handrail singlely, user's forearm is unsettled too many on handrail, can be uncomfortable, and clumsy, the complex structure of existing adjustable handrail profile, the production cost height is difficult for installing and maintain and replace.
The utility model content
The purpose of this utility model provide a kind of simple in structure, regulate flexibly and the low lift armrest of production cost.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of lift armrest comprises: holder, have with whole handrail fixing on the seat the department of assembly and be arranged on the oblique straight-bar of top, department of assembly; Movable shell is set on the described oblique straight-bar with being slidingly matched, and movable shell cooperates the relative horizontal plane in back to form slanted angle with oblique straight-bar; The lift adjustment assembly, the position that the oblique relatively straight-bar of control movable shell slides; The handrail holder is arranged on the movable shell top.
The utility model is by being provided with an angle of inclination with oblique straight-bar and movable shell, can be so that movable shell move obliquely, thus realized the bidirectional modulation of vertical height and front and back position; The lift adjustment modular construction that adopts is simple, easy to operate.In addition, it is low that the utility model also has cost of manufacture, the advantage of installing easily and keeping in repair.

The specific embodiment
In conjunction with Figure 1 and Figure 2, the lift armrest that present embodiment provides comprises: holder 1, movable shell 2, handrail holder 3 and lift adjustment assembly.
Described lift adjustment assembly comprises direction switch spare 51, elastic component 55 and snap device, direction switch spare 51 has the finger pressing section 511 and the actuating arm 512 of formation " 7 " font, its junction is arranged in the movable shell by rotating shaft 52 rotationally, it is outside for operation that movable shell 2 is stretched out in finger pressing section 511, specifically be that fluting by supporting seat 21 lower ends stretches out, actuating arm 512 stretches in the cavity 121 of oblique straight-bar 12.Described snap device comprises on the actuating arm 512 the described draw-in groove of offering on the fixture block 56 that is provided with and oblique straight-bar 12 sidewalls 122, separates to cooperate under the effect of manual piece and elastic component.In the present embodiment, the one-body molded rotating shaft 52 in the junction of finger pressing section 511 and actuating arm 512, rotating shaft 52 embeds in the rotary axis groove that provides on the movable shell 2, and the top is provided with briquetting 53, and briquetting 53 is compressed downwards by handrail holder 3.Elastic component 55 in the present embodiment is irregular shape shell fragment, is arranged on actuating arm 512 lower ends, replaces with oblique straight-bar 12 inwalls to cooperate.Fixture block 56 is arranged on actuating arm 512 bottom sides, fixture block 56 under direction switch spare 51 and elastic component 55 drives with oblique straight-bar 12 on draw-in groove 122 chuckings or separate, thereby locking or unclamp between control moving sleeve 2 and the oblique straight-bar 12.
As shown in Figure 3, when pushing finger pressing section 511, actuating arm 512 serves as axially to turn left to move elastic component 55 pressurizeds with rotating shaft 52, make the draw-in groove of offering on fixture block 56 and oblique straight-bar 12 sidewalls 122 separate, can regulate the height of the oblique relatively straight-bar 12 of moving sleeve 2 this moment; As shown in Figure 4, when loosening finger pressing section 511, elastic component 55 resets, and actuating arm 512 turns right, and fixture block 56 cooperates at the draw-in groove offered 122 under the elastic force effect and on oblique straight-bar 12 sidewalls, thereby realizes the location after the highly adjusting.
The spacer pin 54 that oblique straight-bar 12 tops are provided be used to limit the lift adjustment assembly relative to oblique straight-bar 12 upwards transition move.Handrail holder 3 makes handrail holder 3, moving sleeve 2 and lift adjustment assembly link into an integrated entity by briquetting 53 downward clamping shafts 52, can move up and down synchronously, referring to Fig. 5.
Below,, should not take off exposure scope of the present utility model based on simple replacement of the present utility model for those of ordinary skills only for the unrestricted the technical solution of the utility model of explanation.For example, the lift adjustment assembly can be other form, and the shape of direction switch spare 51 is not limited to " 7 " font, and 512 of its finger pressing section 511 and actuating arms form a suitable angle and get final product; Fixture block 56 can exchange with draw-in groove 22 positions; Rotating shaft 52 can be separate piece, cooperates with direction switch spare 51 versatilely; In addition, movable shell 2 upper ends can not be provided with special-purpose supporting seat 21, directly fixedly connected with handrail holder 3 or one-body molded.Oblique straight-bar 12 also can be one-body molded or fixedly connected ground mode is arranged on 11 tops, described department of assembly; In addition, be understandable that elastic component 55 can also adopt other form, as coil spring or torsion spring, certainly, elastic component also can be arranged on finger pressing section 511 or rotating shaft 52 places.
