Description
Technical field
The present invention relates to a kind of stool, especially there is the stool of rotatable adjusting angle backrest.
Background technology
Stool sits traditional furniture thereon for people, and its structure is simple, light, is suitable for mobile, and no matter in family, or various management place uses all in a large number.
But from structure and fuction, the essential distinction of stool and chair is that chair has the chair back and leans on for people, use more comfortable, laborsaving, and how existing traditional stool structure changes, it does not have the structure of the chair chair back, human body back all can not be given when people is seated on stool to support, therefore cannot bring comfortable, the laborsaving seat sense so of picture chair.
Summary of the invention
The object of the present invention is to provide a kind of stool being provided with the rotation adjustment backrest that structure is simple, support strength is good, make it namely possess the advantage of light, the easy movement of stool, also there is comfortable, the laborsaving experience that chair has simultaneously.
The object of the invention is to have come by following technical solution, a kind of stool, there is the leg member of substructure member and base for supporting component, it is characterized in that, also comprise backrest, this backrest has: unidirectional hinge member, and this unidirectional hinge member is symmetricly set on stool, and it has unidirectional support and oppositely adjusts back reset function; And back support component, this back support component is connected between two unidirectional hinge members of symmetry, and rotates freely above stool along with unidirectional hinge member.
Described unidirectional hinge member, comprises hinge dish, handle and connector, and described handle is connected with back support component, and unidirectional hinge member is fixed on stool by described connector.
Stool of the present invention is initiated and is installed unidirectional hinge member in traditional stool both sides, installs back support component between unidirectional hinge member, thus makes back support component can rotate adjustment up and down around stool.When back support component turns to side on stool, utilize the unidirectional supporting role of unidirectional hinge, just can be used as the chair back and use, with support human body back, reach comfort for sitting posture labor-saving effect.And when not needing back-supported, utilize the reset function of unidirectional hinge member by back support component for adjusting to stool bottom.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention:
As shown in Figure 1, a kind of stool, has the leg member 20 of substructure member 10, base for supporting component, and backrest, this backrest has: unidirectional hinge member 30, and this unidirectional hinge member is symmetricly set on stool substructure member 10, and it has unidirectional support and oppositely adjusts back reset function; And back support component 40, this back support component is connected between two unidirectional hinge members of symmetry, and rotates freely above stool along with unidirectional hinge member.
As Fig. 2,3, unidirectional hinge member 30 overall structure comprises hinge dish 31, handle 32 and connector 33, and handle is connected with back support component 40, and unidirectional hinge member is fixed on stool by connector.
Introduce the detailed construction of each part below:
Each composition component diagram of unidirectional hinge member as shown in figs. 4 through 10, and installation diagram.
Connector 33 comprises rectangle side's plate 331, and respectively there are four perforates be spirally connected with stool at the party's plate two ends, and centre is welded and fixed pipe 332, the hexagonal screw rod 333 of welded bands internal thread hole in pipe.
Hinge dish 31 comprises gripper shoe 311, little tooth 312, gear 313, gear 313 is fixed with the hexagonal screw rod of connector, the fixing support forming band groove of gripper shoe 311 of two pieces of symmetrical spacing distances, and gripper shoe 311 holder pivots is engaged on gear 313, and handle is fixed on the gripper shoe support other end, little tooth, gear to be located in support groove and corresponding occlusion.
Groove two ends in gripper shoe form the first connecting portion 311A and the second connecting portion 311B, first connecting portion has four screws be connected with screw, to be connected and fixed handle 32, the second connecting portion forms circular hole 311C, there is through hole 313B at gear 313 center, and two ends form protruding hole wall 313A.And through hole 313B is the inner hexagonal hole with hexagonal screw rod corresponding matching, hexagonal screw rod coordinates fixing with gear hexagon ring, to be fixed between rectangle side's plate 331 screwing and hexagonal screw rod by gear to also have packing ring by screw and hexagonal screw rod 333 internal thread hole.Gear 313 hole wall 313A outer wall is circular, and is rotatably assorted with two circular hole 311C of symmetric support plate.
Have two bullport 311D in the middle part of two pieces of gripper shoes, this bullport assembles little tooth 312 by bearing pin, makes that the ratchet of little tooth is corresponding with the tooth of gear 313 to be engaged, and ratchet and tooth are arranged due to curvature simultaneously, makes both unidirectional occlusion fix, reverse slide cooperation.The two ends, tooth portion of gear form block 313C, and little tooth one end is formed and coordinates the positive stop end 312A stoping little tooth to rotate with block, and the other end forms the sliding end 312B of inclination.
Handle 32 is positioned at groove inside and forms the groove 321 holding little tooth, and be provided with shell fragment 314 in groove, little tooth is suppressed laminating gear by this shell fragment.
As shown in Figure 5, when little tooth spiral forwards initial threshold position to, block 313C coordinates with positive stop end 312A and just stops little tooth and gripper shoe to be rotated.As shown in Figure 6, when little tooth spiral forwards maximum angle extreme position to, block 313C and little tooth 312 sliding end 312B is slidably matched, and little tooth top is gone out gear, and bearing pin synchronously slides and makes it reset until eject little tooth in locating hole simultaneously.
As shown in Figure 2,3, hinge dish also has housing 315 outward, and this enclosure interior is mounted with the support that gripper shoe is formed, and its one end forms the perforate of passing with pipe, and is fixed by the hexagonal screw rod of screw and pipe; Its other end makes handle stretch out, and makes handle install back support component.
As shown in Figure 1, 2, 3, back support is a bow 40, bow is made up of the grafting of three sections of arc-shaped rod 41, arc-shaped rod 41 both ends symmetrical shape, and end portion into two, be arranged with grafting block 411 and the slot 412 of negative and positive symmetry, the grafting block 411 of arc-shaped rod one end, slot 412 just coordinate fixing with the slot of adjacent another arc-shaped rod coordinated, grafting block.For making not easily to depart between arc-shaped rod, between the grafting block of the arc-shaped rod coordinated between two, be also provided with symmetric windows 413, symmetric windows forms rectangular opening, this rectangular opening grafting locating piece 414.Bow two ends form the hole slot of grafting handle, and handle and arc-shaped rod to be fixed by being spirally connected.Bow is also set with cushion 42, and cushion is made up of spongy layer and suitcase covering layer.
The leg member 20 of substructure member 10 and base for supporting component is all made up of a ring, arranges corresponding jack between two rings, grafting support bar 21 between jack.Ring is all made up of four sections of arc-shaped rod grafting, and its structure is identical with back support bow 41, omits structure herein and describes.
Along there being concave station 11 in substructure member 10 ring, fixed support bar 12 is gone back in inner side, concave station, support bar is installed round and elastic cushion 13, and passes through screw fastening.
