The improvement of this creation convertible picnic tables and chairs, its preferred embodiment sees also shown in the 1st, 2 figure, and it is made up of a Picnic table 10, fixed mount 20 and two seat supports 30, wherein:

This Picnic table 10, shown in the 1st figure, it has a rectangle desktop 11, be concaved with the containing part 12 of two long rectangles in desktop 11 bottoms, and one side inner edge place is provided with one and is the portion that begins a new line 13 of the groove gripping portable of accommodating in the bottom, in addition respectively be provided with the extension foot rest 14 that to do folding in desktop 11 two bottom sides, this extends foot rest 14 and is made up of backstay 141 and two expansion links 142, wherein, these backstays 141, but be parallel be fixed on the transverse bar 143 that rotates one original place, desktop 11 bottoms and push-jump before and after can doing, positon of near bottom such as Yu Qi also is provided with an open-work 141a; And this expansion link 142, be arranged in the backstay 141 and can do and move up and down, the bottom also is provided with a suitable long bar 144 that supports jointly, can be stable on the ground, and in proximal portion one perforation 142a be arranged, again, expansion link 142 inside are provided with an elasticity clamping piece 15, and this clamping piece 15 has a bending shell fragment 151 and a card button 152, shown in the 3rd figure, when expansion link 142 was outwards pulled out, this card button 152 can pass perforation a few open-work 141a of 142a and expansion link 142 and backstay 141 is prolong affixed.

Fixed mount 20, be articulated in respectively between backstay 141 bottoms and desktop 11 bottoms two connecting rods 16, form bent Y type support body by a headtree 21 and a pole 22 pivot joints, impel its unlikely bending inwards to support extension foot rest 14 during expansion, respectively be coated with in addition a holding ﹠ forming knot 17 on this connecting rod 16, this holding ﹠ forming knot 17 has a buckling parts 171 that is C type clip shape.

Seat support 30, shown in second figure, it has the long rectangle seat 31 that can be placed in these Picnic table 10 containing parts 12, these seat 31 bottoms are concaved with an accommodation section 32 again, and in reaching a two bottom sides pivot joint one bent support foot rest 33 that folds and can be concealed in this accommodation section, this support foot rest 33 is connected with a cross bar 332 by two montants, 331 bottoms and forms, other has a flexible fixed mount 34 to be articulated in montant 331 bottoms and seat 31 bottom center places, also have a headtree 341 and a pole 342 as for the structure of this fixed mount 34 is same as above, so at this Ao Shu no longer, all the other make support foot rest 33 be unlikely to curve inwardly when launching.

More than be this structure of creating each member of a preferred embodiment and the explanation of relevant position thereof, then, again with its occupation mode statement as after, believe structural feature and advantage, can obtain further understanding and approval.

The expansion action of this Picnic table 10, shown in the 1st figure, be with backstay 141 outer pulling out, make headtree 21 and the pole 22 of fixed mount 20 be to finish and launch and nationality makes its unlikely bending inwards to resist backstay 141, at last, again expansion link 42 is pulled out downwards, till this card knob 152 convexedly stretches in this hole 142a and other hole 141a.Impel Picnic table 0 to have certain altitude; And the expansion of this chair table 30 action shown in second figure, is directly the trunk 31 outer headtrees 341 that can drive fixed mount 34 simultaneously of pulling to be launched with pole 342, and nationality makes its unlikely bending inwards to reach the purpose of this support foot rest 33 of support.

As for the folding for storing action of this creation Picnic table 10 with seat support 30, see also shown in the 4th figure, be with seat support 30 upper rack posts 342 and the bending of headtree 341 articulated sections, again the support foot rest 33 of both sides is inwardly amounted to, impel support foot rest 33 to be and be placed in fully till the accommodation section 32, then, 30 folding and unfoldings of the seat support after folding are placed the containing part 12 interior (this creation is the example explanation to put a seat support 30) of this Picnic table 10.Make seat support 30 end faces face the bottom surface of Picnic table 10, with this card button 152 of both hands thumb press it no longer being blocked again knows on the open-work 141a of backstay 141 so can smoothly these expansion link 142 collections be gone in the backstay 141, last again the headtree 21 of fixed mount 20 is articulated support bar 22 bendings in it, impel on the extension foot rest 14 that inwardly folds support bar 144 both sides can suppress be positioned at containing part 12 chair table 30, make seat support 30 spacing do not get loose (shown in the 5th figure), at last, the portion of amounting to 171 button of this holding ﹠ forming knot 17 is tied in seat support 30 again and acted in collusion and do not fall to take off, it is little and be convenient to portable when this begins a new line portion 13 in gripping to reach the collection volume.

So, the improvement of this creation convertible picnic tables and chairs is in doing that Picnic table 10 bottoms of amounting to are recessed two containing parts 12 with extending foot rest 4, its grade can be for clothing 0 capacity that folds bracing frame 33 backs in it, and nationality should support bar 44 by these holding ﹠ forming knots 17 and this cross bar 32 acts in collusion, make shaken bar 144 of seat support resist spacing and do not fall to take off, be with, this creation can be concealed in these seat supports bottom the Picnic table simultaneously with simple member designs, make that collection body axletree terminal is little and do not take up space, and it is easy to carry when going out, when launching to use, then have this Picnic table 10 and two seat supports 30 simultaneously, can finish its practical effect of performance.

In sum, this creation is real in like product its splendid progress practicality, and extremely convenient on using; In addition, this is created before application and there is no identical article and see publication or public use.

The above person only is the preferable possible embodiments of one of this creation, so use this creation specification and the equivalent structure variation for it of claim institute such as, ought to be included in the claim of this creation.
