Detailed description of the invention:
Embodiment one:
Referring to figs. 1 through Fig. 6, conjoined jack-knifing table and chair external member, comprises the desk 1 and two chairs 5 with folder function.
Chair 5 comprises the identical or symmetrical feet in both sides 6, cushion 7 and back cushion 8; Feet 6 comprises cross one another front support rod 61 and back support rod 62, front support rod 61 extends and forms backrest section 63 above cushion, and in two backrest sections 63, back cushion 8 is installed, cushion 7 is positioned on front support rod 61 and back support rod 62, formation front support rod 61 and back support rod 62 can close up the structure of folding, and this is also modal folding chair structure in prior art.
The structure of the preferred folding seat of this example is as follows: described cushion 7 is arranged on cushion rod 71, and this cushion rod 71 front portion is movably articulated in back support rod 62 upper end, rear portion is movably articulated in the middle part of front support rod 61; Front support rod 61 and the mutual intersection of back support rod 62 refer to and front support rod 61 are hinged with a sliding sleeve 64, back support rod 62 is through this sliding sleeve 64, back support rod 62 is fixed with a limited block 65 above crosspoint, chair is opened and is put in place, sliding sleeve 64 is conflicted on this limited block 65, formation activity chi structure and stressed support.And between two sliding sleeves 64, be hinged with the second cross bar 67, both can strengthen the lateral stressed of infall in front support rod 61 and back support rod 62, improve chair stability, what also can ensure that folding operates smooth-goingly carries out.
Further, cushion rod 71 is made up of two parallel bars, between two rod members are movably articulated in the middle part of back support rod 62 upper end and front support rod 61 respectively; The cushion rod 71 be made up of two parallel bars, can dodge out the space that cushion 7 is subject to gravity descending, avoids the holder of cushion rod local under people's leg, produces bad experience; Both sides front support rod 61 is bent into front U-shaped frame by a rod member, and the front rail 611 of this front U-shaped frame is in one end of backrest section 63, has both improved backrest section 63 intensity, also can be folding operation or the position providing hand to grab when carrying; Back support rod 62 is bent into rear U-shaped frame by a rod member, the rear transverse rod 621 of this rear U-shaped frame lands, and between both sides back support rod 62, be also hinged with the first cross bar 66, and this first cross bar 66 is in the opening part of rear U-shaped frame, after avoiding cushion rod 71 stressed, both sides back support rod 62 is toward inside contracting; The feet 6 of chair 5 both sides forms rigidity relational structure by the first cross bar 66, front rail 611 and rear transverse rod 621, provides load-carrying members; In addition, described cushion 7 and back cushion 8 except the pre-formed sheet material of routine, foam-rubber cushion, this example preferred flexible material, as oxford and elasticity rope band, its both sides are be located in the backrest section 63 of cushion rod 71 and front support rod 61 respectively, and both portable folding was also space-saving, are especially applicable to outdoor use.
Desk 1 comprises table leg 2 and the desktop 3 of both sides cross-articulation, table leg 2 is formed by two U-shaped bar 21 cross-articulation respectively, the top cross bar 211 of two U-shaped bars 21 is used for locating and supporting desktop 3, at least two U-shaped bars 21 of table leg side have extension 212 downwards from cross-articulation point 22, this extension 212 is hinged on the bottom of the front support rod 61 of two chair 5 homonymies respectively, two chairs 5 upwards extend at the back support rod 62 of this side and are hinged on another root U-shaped bar 21 above cross-articulation point 22, by the local of homonymy two U-shaped bar 21, and the local of chair front support rod 61 and back support rod 62 forms double leval jib linkage supporting structure.Further, the end, extension 212 of described U-shaped bar 21 has bending cross bar 213, the end of this bending cross bar 213 is hinged on the front support rod 61 of described chair 5 opposite side, utilize this bending cross bar 213, association is formed to the front support rod 61 of chair both sides, both improved front support rod 61 bending U-shaped frame bottom intensity, otherwise also unsettled to side desk 1 plays stable support function, avoid toward unsettled LRO Lateral Runout, as Fig. 2.
Described desktop 3 is rigidity foldable structure, and middle part is hinged by hinge structure 31, and desktop 3 both ends are positioned in the top cross bar 211 of U-shaped bar 21 respectively, and desktop 3, when two U-shaped bar foldings, can fold along hinged place and pack up; More particularly, described desktop 3 is made up of central layer 32 and the flexible fabric 33 with waterproof, and flexible fabric 33 is wrapped in outside central layer 32, and surrounding is by making or be compounded to form bound edge 331; Have gap bound edge in two panels central layer 32 adjacent portions, namely this gap bound edge defines the hinge structure 31 that can fold and pack up; The bound edge 331 at desktop 3 two ends, by after steel disc 34 winding, locks in the top cross bar 211 of described U-shaped bar, as Fig. 5 and Fig. 6.
For this reason, need on the downside of desktop 3 to be designed with a support rail 35, as Fig. 2 and Fig. 3, these support rail 35 two ends have bending section 351, also namely U-shaped structure is bent into by rod member, the end of this bending section 351 is hinged on the top of a described U-shaped bar 21 cross-articulation point 22 respectively, a hinged support bar 36 on another root U-shaped bar 21 extension 212 below cross-articulation point 22, and support bar 36 other end is hinged on a bending section 351 of support rail 35; Bottom the desktop 3 that support rail 35 is conflicted bottom desktop 3 hinge articulated section or near hinge articulated section, to the middle supporting role of folding desktop 3.As Fig. 3, further, be provided with frenulum 37 bottom desktop 3, this frenulum 37 is set on support rail 35, descending by support rail 35 during folding, the down folding of traction desktop 3.
Embodiment two:
With reference to Fig. 7, in this example, desktop 3 is rigid unitary, also full wafer sheet material is, one bottom portion is movably set in the top cross bar 211 of a U-shaped bar 21 by kink 38, be provided with Elastic buckle 39 bottom the other end, desktop 3 fastens by this Elastic buckle 39 and is positioned in the top cross bar 211 of another U-shaped bar.In this structure, without the need to extra support, but piece desk and chair is opened or folding time, namely must increase an action, also namely as shown in phantom in FIG., desktop 3 need be dug, just can set level for or realize folding.
In sum, the piece desk and chair that example provides is preferred version, and desktop is hanging structure, dodges out the space of side, for legs and feet turnover and activity space, can obtain optimum experience; Do not get rid of the U-shaped bar 21 of table leg 2 both sides; all from cross-articulation point 22 simultaneously to downward-extension, there is extension 212, and be hinged on front support rod 61 bottom of chair 5 homonymy; and forming four pin stable support of desktop 3, this structure also should belong to the scope of this patent protection.The utility model desk 1 and chair 5 disjunctor scheme, be applicable to existing any both sides and become on the chair of X intersection, formation has association and opens and folding structure conjoined jack-knifing table and chair external member, and is not limited to the chair scheme of this example.
