The specific embodiment
Overall adjustable folding chair of the present invention comprises chair frame 1; The chair back 5 is installed on the chair frame 1; The chair back 5 bottoms are connected with seat 7, and chair frame 1 left and right sides is connected the relative inclined of the glide direction of first sliding pair through first sliding pair respectively with the chair back 5 bottoms; Connect chair back bearing 34 on the chair frame 1; Chair back bearing 34 left and right sides are connected with the chair back 5 tops through second sliding pair respectively, and the chair back 5 slides along relative chair frame 1 orientation with second sliding pair of first sliding pair with seat 7, install on the chair back 5 to be used to regulate the chair back 5 and the positioner of seat 7 with respect to chair frame 1 angle.The first sliding pair position symmetry of chair frame 1 left and right sides, angle, length and width are all identical, and chair back bearing 34 can be interconnective two parts with chair frame 1, also can be made into one.When people need regulate the angle of seat; Can unclamp positioner, make first sliding axle 3 and second sliding axle 8 can distinguish first sliding pair and the slip of second sliding pair, because first sliding pair with respect to the horizontal plane tilts; Therefore seat also can forwards moved when move the bottom by the first sliding pair top; The rear space that has taken when having dwindled chair back layback made full use of the front-seat space of seat, and the angle between the seat 7 and the chair back 5 remains unchanged; Compare with the existing seating product that only can regulate chair back angle, comfortableness is higher.
The present invention can be at the chair back 5 bottom installation brackets 4 in order further to make full use of the space, and carriage 4 one ends are installed horizontal rotating shaft 6, and laterally rotating shaft 6 is hinged with seat 7.Seat 7 can rotate along horizontal rotating shaft 6, when seat does not use, can seat 7 relative ground vertically be turned up, and enlarges the front-seat space of seat, is convenient for people to pass through; When people need use seat, can seat 7 be set level the back and use.
The sliding type that first sliding pair of the present invention and second transmission all preferably adopt chute to cooperate with sliding axle; Concrete structure is following: said first sliding pair has a pair of oriented groove 2 that is separately positioned on chair frame 1 left and right sides, and the left and right sides, the chair back 5 bottom is installed first sliding axle, 3, the first sliding axles 3 respectively and inserted in the oriented groove 2; And along 2 slips of oriented groove; Said second sliding pair has a pair of chute 9 that is opened in the chair back 5 left and right sides respectively, and chair back bearing 34 left and right sides are installed second sliding axle, 8, the second sliding axles 8 respectively and inserted in the chute 9; And along chute 9 slips, this structure has advantages such as slip is smooth and easy, glade plane space is little.According to actual needs; Can also the chute 9 of second sliding pair be opened in chair back bearing 34 left and right sides; And second sliding axle 8 is installed in the chair back 4 left and right sides; Second sliding axle 8 is inserted in the chute 9, and slides along chute 9, and the structure of second sliding pair realizes in this structure and the preferred version function and result of use are identical.Certainly first sliding pair of the present invention and second transmission can also adopt slide bar and multiple structures such as sliding sleeve cooperates, but aspects such as smooth and easy degree and the glade plane space of these structures when slip all with preferred structure gap to some extent.
Positioner of the present invention can adopt multiple structure to realize that embodiment is following:
Embodiment one:
Positioner of the present invention has one to be installed in ground first even hinge block 10; First even hinge block 10 is hinged with the lower end of regulating cylinder 11; Regulate the expansion link 12 and first back-moving spring 13 are installed in the cylinder 11, the upper end of expansion link 12 is connected with the chair back 5 through second even hinge block 14, regulates cylinder 11 upper end installing and locating covers 15; Setting-up eccentricity wheel 16 in the positioning sleeve 15, the wheel shaft of eccentric wheel 16 is connected with first regulating handle 17.When needing the location, drive eccentric wheel 16 rotations through first regulating handle 17, make eccentric wheel 16 extruding expansion links 12, expansion link 12 closely contacts with positioning sleeve 15, locks through the angle of frictional force to seat; When needing to regulate chair angle, unclamp eccentric wheel 16 through first regulating handle 17 and get final product.This structure can realize step-less adjustment to chair angle, and is of many uses.
Embodiment two:
Positioner of the present invention has a spacer 18 that is hinged with first sliding axle 3; Offer locating slot 19 on the spacer 18; Chair frame 1 side is provided with reference column 20, and oriented groove 2 lower wall are offered first reset tension spring 22 is installed between location translot 21, the first sliding axles 3 and the chair back bearing 34.When needing the location; First sliding axle 3 is moved in the location translot 21 of correct position, positioning of rotating sheet 18 makes the locating slot 19 on the spacer 18 block reference column 20; Reference column 20 gets into after the locating slot 19; First sliding axle 3 can't move forward, and promptly can't in the translot 21 of location, shift out, and chair angle is accomplished locking; When needing to regulate chair angle, positioning of rotating sheet 18 separates locating slot 19 with reference column 20, and first sliding axle 3 is got final product from locating to lock again in the location translot 21 that shifts out and move to another position in the translot 21.This structure location is reliable, firm, and the location back seat has no the free gap.
Embodiment three:
Positioner of the present invention has a slide rail 23 that is connected with support 1; First locating hole 25 is offered in slide rail 23 bottoms, and slide block 24 is installed in the slide rail 23, offers second locating hole 26 on the slide block 24; Slide block 24 end faces are provided with location-plate 27; Location-plate 27 bottom surfaces are provided with alignment pin 28, and location-plate 27 end faces are installed second regulating handle 31, and slide block 24, location-plate 27 all are hinged through the lower end of the 3rd even hinge block 29 with the chair back 5; Second back-moving spring 30 is installed between the location-plate 27 and the chair back 5, second reset tension spring 33 is installed between the chair back 5 and the chair back bearing 34.When needing to regulate chair angle, drive location-plate 27 through second regulating handle 31 alignment pin 28 is extracted in first locating hole 25 and second locating hole 26, this moment, slide block 24 can be free to slide along slide rail 23, and chair angle is regulated; When needing the location; Unclamp second regulating handle 31, location-plate 27 automatically resets under the effect of second back-moving spring 30, alignment pin 28 is inserted in second locating hole 26 of first locating hole 25 and proximal most position; With the locking position of slide block 24, promptly accomplish location to seat.This structure position fixing process can be accomplished automatically, and is easy to operate.
The angle of the angle a of oriented groove 2 horizontal directions of the present invention is generally 30 °-60 °.If the angle of angle a is excessive, surpass 60 °, then the adjustable range at the seat elevation angle is too small; If the angle too small of angle a, then the distance that moves forward of seat is excessive, can't make full use of rear space, therefore combines actual operating position, and the angle of angle a is decided to be 30 °-60 °.The present invention can be made as 45 ° with the angle of the angle a of described oriented groove 2 horizontal directions, and this angle can satisfy the use needs of most of occasion.
The present invention can auto-folder after the people leaves in order to ensure seat 7, and balancing weight 32 can be installed in seat 7 bottom surfaces.Balancing weight 32 can increase the weight difference of horizontal rotating shaft 6 both sides seats 7, and after the people left, seat 7 can rotate to the state vertical with respect to ground automatically.
