Abstract
The utility model provides an arbitrary angle adjustable swivel chair. The center of the circular annular bottom is plugged with a supporting seat which is inserted by a pivot shaft built-in the bottom edge of the U-shaped type support bracket. The support bracket is provided with a telescopic rod pin connected with the chair seat, and the chair back and the chair seat are pivot type. The chair back is also pivoted on the arm rest of the support bracket, so when adjusting the separation angle of the chair back and the chair seat, because of linking with the telescopic rod and supporting, the angle can be changed arbitrarily and easily. Using the against buckle of the attaching rod on the sleeve pipe sheathed outside the telescopic rod, the utility model can be used as a common chair or changed to a deck chair, and concurrently as a swivel chair.
Description
The utility model relates to a kind of turning chair of adjustable angle.
The chaise longue of traditional chair such as turning chair and adjustable angle belongs to independently pattern; I.e. each tool simple function only, simultaneously because of comparatively complicated on the structure, the space that occupies is bigger, cost is also higher, for only needing rotation merely or couching, can't reach light in fact, the easy effect of operation, and must be respectively rotation or couch and prepare two chairs, not only increase the expenditure of cost, more occupy more space, when reality is used, must change or display simultaneously again, form inconvenience and cause puzzlement, and its angle employing segmented operation of lying of inclining of the chaise longue of most simple types, the not continuous adjustable effect of tool, difficult different needs according to everyone obtains more comfortable inclining and lies.
The utility model main purpose is to provide a kind of can have the effect of 360 deg rotation and the angle of inclination between the continous way adjustment chair back and seat support simultaneously, and can the chair back be fixed on the unspecified angle according to individual demand, the practical function that reaches stand or couch, and simple in structure, processing ease adjust turning chair at any angle.
According to a kind of turning chair at any angle of adjusting of the present utility model, this turning chair has the base of an annular, be provided with void column shape supporting base in the middle of the base, to insert embedding one and " U " word shape support root edge pivot of build-in mutually, and make support can do the 360 deg revolution simultaneously together with the seat support that is installed on it and the chair back, an and expansion link that is articulated with seat support on the mat support, make when adjusting length of telescopic bar, be articulated in the handrail of support because of the chair back, and be movable pivot joint with seat support, articulate the fulcrum rotation and produce interlock around each, can change the angle of the seat support and the chair back, it is characterized in that:
The pivot connecting plate of support connects extension one hollow rod shape sleeve pipe, preceding pipe end is provided with the pin of a holder support, and sleeve pipe is nested with the quill shaft sleeve pipe that two ends are provided with neck bush, and establish an oval shaft-like expansion link and run through this pipe spreader, and respectively be horizontally set with a backing pin near the expansion link two ends, the front end end is horizontally set with the short pipe of a hollow, and is articulated with the pin joint seat of seat support bottom surface; Be convexly equipped with one relative with the neck bush position of inner shaft sleeve pipe and have the short column of screwed hole at sleeve pipe pipe face, it is screwed into a bolt, this bolt one end then locks in the L-shaped shaft-like rod end hollow sleeve letter of withholding bar admittedly, and mat is withheld the pole face that the moving rotation of the plate of bar makes the other end compressing of bolt or breaks away from expansion link;
The side rod appropriate location of chair back both sides and the handrail end of support bending are articulated with bolt, and the formation point action, and the chair back and seat support are articulated, the formed fulcrum of pin joint seat that cooperates seat support below and expansion link to articulate, in the time will changing between the chair back and seat support angle, adjust length of telescopic bar and the interlock seat support, and to make the chair back serve as the axle rotation with the both sides pivoting point, and can continuously change its angle.
Below, lift a specific embodiment, and conjunction with figs., the benefit that describes structure of the present utility model, feature in detail and reached:
Fig. 1 is the three-dimensional exploded view of embodiment of the present utility model.
Fig. 2 is the stereogram of embodiment of the present utility model.
Fig. 3 is a phantom of the present utility model.
Fig. 4 is the action schematic diagram of embodiment of the present utility model.
See also shown in Figure 1, turning chair comprises a base 1 that is annular, central authorities are provided with a hollow cylindrical supporting base 12, extended three of anchor ring by base is bent upwards arcuation rib 11 and is used to be connected hollow short cylindrical shape supporting base 12 and base 1, turning chair comprises that also one bends to the support 2 of " U " word shape by round bar, its " U " word shape bottom pole face fixedly connected one is the pivot connecting plate 21 of " Contraband " shape, plate is provided with through hole, the one awl end with shaft-like pivot 22 of a frusto conical ends inserts above-mentioned through hole and compresses, the other end of pivot 22 then inserts in the hollow shaft housing 23 that an outer ring edge has croze, and make axle sleeve 23 inject the centre of supporting base 12 after connecting, make support 2 can do the 360 deg rotation.
Connect extension one hollow round bar shape sleeve pipe 24 by pivot connecting plate 21, be subjected to pin 25 support of holding in the palm that is " V " shape that is connected on " U " shape two side levers at the bottom of its front end bar.Pipe at sleeve pipe 24 is nested with a quill shaft sleeve pipe 3, see also shown in Figure 3, two pipe ends of pipe spreader 3 respectively are provided with neck bush 31, use braking one oval shaft-like expansion link 4, and respectively be horizontally set with a backing pin 41 near the two ends of expansion link 4, limiting flexible length, and avoid whole to pull out slippage, and the front end end of expansion link 4 is horizontally set with the short pipe 42 of a hollow, and it is articulated on the pin joint seat 61 fixing on seat support 6 bottom surfaces with Pivot 62.Vertically be convexly equipped with simultaneously a short column 241 with screwed hole on the sleeve pipe 24, its outer radial that is positioned at pipe spreader 3 lower shaft linings 31 stretches out, be provided with in the short column 241 one with withhold the bolt 51 that bar 5 is threaded, be " L " shape and withhold bar 5, rod end is provided with a hollow sleeve 52, the tube face is provided with a plurality of screws and is used for fixing bolt 51, but thereby the moving turn buckle depression bar 5 of plate make bolt 51 compressings or disengage the pole face of expansion link 4 so that expansion link 4 is fixing or move.
See also Fig. 1 and Fig. 4, seat support 6 and the chair back 7 be in the pivot joint mode two sections movable, therefore and the pin joint seats 6 that articulate before seat support 6 bottom surfaces and the expansion link 4 formation fulcrums equally 7 liang of side levers of the chair back, two crooked handrails 26 on appropriate location and support 2 articulate with bolt 27 respectively.When adjusting the angle of the seat support 6 and the chair back 7, loosen earlier and withhold bar 5, and force in seat support 6 according to the weight of human body itself, or the strength that human body lies low backward imposed on the chair back 7 and adjust the collapsing length of expansion link 4, the chair back 7 of interlock seat support 6, and drive simultaneously articulates bolt 27 rotations on handrail 26, and changes the inclination angle of the chair back, plate is moving again withholds bar 5, makes bolt 51 compressing expansion links 4 and is fixed.
In sum, the utility model not only has the function of rotatable 360 deg, more can the effect of the simple mechanism of mat reach the function of any adjustment chair back and seat support angle, and have the comfortable convenience in the space of saving, the practical value of increasing economic efficiency.
