Description

Table or desk with stowable legs

The utility model relates to a kind of Table or desk with stowable legs, refers to a kind of bracing frame that can be used for table, chair especially.

For ease of user's use that is easy to carry about with one, or collection the time does not take up space, at present as table, apparatus persons such as chair, but adopt structural design mostly with folding, but and folding table at present, the structural design of chair is similar, but following head is example for the outdoor simple type folding chair tool that uses of people, please cooperate and consult Fig. 7, this chair tool mainly comprises a deployable bracing frame that folds 4 and a soft cushion cloth 5, its bracing frame 4 has two cross bars 40 that are fixedly arranged on two opposite side places, cushion cloth 5 front and back respectively, parallel cross bar 40 two ends, two front and back are respectively towards the sagging support bar 41 that is provided with, two support bars, 41 middle section positions that are positioned at both sides intersect and put and be that a pivot 42 runs through and is pivoted, and constitute a deployable folding chair that folds.

During use, make the support bar 41 of bracing frame 4 both sides revolve exhibition respectively towards front and back, and make two cross bars 40 on the bracing frame 4 revolve under the exhibition drive at support bar 41, drawing cushion cloth 5 both sides are launched into the plane that can sit; During folding, make support bar 41 cycle inwardly of bracing frame 4 both sides and close, and mat two cross bars 40 retract cushion cloth 5 and fold.

Structure as for the folding desk, it also has above-mentioned identical support frame structure equally, the table that on the support bar of bracing frame, is pivoted in addition, and become a foldable desk kenel, as for its launch, but the mode of folding is general identical with above-mentioned folding chair tool, below promptly repeat no more.

But the folding tables and chairs are simple type tables and chairs that a kind of people's of specializing in open air use or on-fixed are put, therefore, its structural design need be in light weight emphatically, it is little to fold the back volume, design focal point such as do not take up space is beneficial to the user and is easy to carrying, portably uses, but but by in above-mentioned traditional folding table, the structure of chair as can be seen, bracing frame after it folds is the type body that is the  shape, still can't be volume, still have the problem that takes up space, cause the user to carry or inconvenience when collecting with minimum.

Moreover, when bracing frame launches, the support bar of its both sides is to support to the exhibition of revolving towards front and back to form, if bracing frame is applied in the structure of chair, and people are when generally being seated at seat, sitting posture is adjusted in conversion constantly unavoidably, avoid ossifing of health, so the twisting when the seat person adjusts sitting posture, normal easily drive folding chair folds immediately, make the seat person be careful when taking, otherwise accidentally easily have the dangerous facts of falling down on the ground to take place; When if bracing frame is applied to table structure, because the main support point of bracing frame is to be positioned at the front and back end, and both sides there is no effective support power, so can't form firm supporting framework, and if the user touches accidentally or when table one side is pushed, promptly can cause bracing frame to fold the peril that table overturns, therefore aspect security, the structure of this Table or desk with stowable legs still has is improved part.

The purpose of this utility model is: provide a kind of chair, the volume of table after the folding of making to minimize, be beneficial to carry the Table or desk with stowable legs of collection, have the very little advantage that takes up space when collection, and be the splendid Table or desk with stowable legs of a kind of security.

The technical solution of the utility model is to provide a kind of Table or desk with stowable legs, and this bracing frame comprises several foldable support bars, it is characterized in that:

The number support bars are that mat one positioning seat group is set as bracing frame, and this positioning seat is all established at least three locating slots in its periphery, locating slot and be the  shape of lateral openings, and each support bar is to be hubbed in the locating slot respectively.

Described Table or desk with stowable legs is characterized in that: this positioning seat is convexly equipped with an oblique limiting section in the cell wall plate root edge of locating slot opening opposite side.

Described Table or desk with stowable legs, it is characterized in that: this support bar is articulated by first body of rod and second body of rod and links, its first body of rod is a  shape bar, second body of rod is inserted first body of rod inside, first body of rod top and cushion cloth are fixed, and second body of rod top is arranged in first body of rod bottom, and cooperates the element that is pivoted together to be hubbed in the locating slot of positioning seat.

Described Table or desk with stowable legs, it is characterized in that: this bracing frame is in the cushion cloth of supporting bar top in conjunction with a chair, install a stator in each supporting bar top, this stator one end has an articulated section, this articulated section cooperates pivot connecting element to be hubbed at supporting bar top, stator in addition end has a Fixed Division, with respectively in conjunction with the end angle of this cushion cloth.

Described Table or desk with stowable legs, it is characterized in that: this bracing frame cooperates the table of a desk, in each supporting bar top one end face is set and has the pull holder of sheet of two-phase corresponding clip, the pull block base of sheet of tool two-phase corresponding clip is set in this table bottom surface, folder is pulled and is fixed with cross bar between two adjacent block bases, and is fixed in this cross bar in the holder of supporting bar top.

Described Table or desk with stowable legs is characterized in that: serve as reasons several long slab bodies and put and wear with elastic strip the plate body that forms of this table.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme advantage of the present utility model as can be known be:

1, can make the volume after the folding minimize: bracing frame of the present utility model is mat one positioning seat for each support bar location that is pivoted, when folding, each support bar is bent to be concentrated and closes fixingly, forms minimum volume kenel, make the user more convenient on carrying, collecting, and do not take up space.

2, steadiness is better: bracing frame of the present utility model makes the uniform periphery that is hubbed at positioning seat of each support bar, during expansion, each support bar revolves exhibition towards each orientation respectively, make it enough form the power of propping up in each orientation, so no matter be to be applied in desk or the Chair structure, all can form a splendid firm effect, and can make the not local external force effect of reason and folding immediately of desk, chair tool, but allow folding table, chair have more security in the use.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
