Abstract

The utility model discloses a positive stop device of a multifunctional chair and coordinates with a support frame which is formed by two movable chair surfaces and two crossed pivotally connected support poles to be implemented, and two chair backrest poles are respectively pivotally connected with external sides of two beams of the chair surface, and the upper parts of the two chair backrest poles are respectively connected with a backrest surface. Wherein, the positive stop device is arranged above or under the jointing part of the two chair backrest poles. As the chair backrest poles are pivotally connected at the two beams at the external sides of the chair surfaces, when the two beams of the chair backrest poles are opposite to the chair surfaces and form an elevation angle, the positive stop device can hold a support pole of the support frame or the chair surface on the back of the chair, thus leading the chair back not to move oppositely without a positive stop, then the function of the chair can be realized.

Description

The stopping means of multifunction chair

Technical field

The utility model relates to a kind of daily life leisure goods, refers in particular to a kind of stopping means of multifunction chair.

Background technology

At present, family product is of a great variety, and is various informative.It is both artistic and practical to be crucial, and the changeable of its function also is dealer's emphasis of exploitation emphatically.

As shown in Figure 1, 2, the most traditional Folding stool, by the stool face 1 of two activities with intersect the bracing frame 2 that the pole 21 that articulates forms by two groups and constitute, each stool face 1 is fixing by two crossbeams 11 respectively, and an end of crossbeam 11 is articulated in the top of bracing frame 2 respectively, so just form a Folding stool that can conveniently fold and launch, certainly, this stool also can be used as a convenient table and uses.But the comfortableness that this Folding stool is seated is limited, and it is seated comfortable not as backed chair after all.Promptly make chair and use, can make the folding seat that desk uses again, its stopping means is the main determining factor that realizes its function.

The utility model content

The purpose of this utility model provides a kind of help chair can realize the folding seat function, can realize the stopping means of the multifunction chair of desk function of use again.

For achieving the above object, solution of the present utility model is: the stopping means of multifunction chair, be to cooperate the bracing frame of forming by the seat of two activities and the pole of intersecting pivot joint by two groups and implement, two chair back rods are the outsides that are articulated in seat two crossbeams respectively, the top of two chair back rods is connected with the backrest face, and wherein stopping means is located at two chair back rods above or below this articulated section.

Described stopping means is provided with " L " type pin that can prop up bracing frame pole below two chair back rods and seat crossbeam articulated section.

Described stopping means is to add bracing piece on the rear of two chair back rods.

The outside two crossbeams of described seat are provided with the keeper that positioning chair leans against bar.

After adopting such scheme, because chair back rod of the present utility model is to be articulated on two crossbeams in the seat outside, when then two crossbeams of the relative seat of chair back rod are an elevation angle, " L " type pin can prop up the pole in the bracing frame, make movable in the opposite direction that the chair back can infinite place, realize the function of chair with this; If add bracing piece on the rear of chair back rod, when then two crossbeams of the relative seat of chair back rod were an elevation angle, this bracing piece can prop up the seat at chair back rear and it is spacing.

The specific embodiment

As shown in Figure 3, the stopping means of multifunction chair of the present utility model, wherein the structure of this chair is similar with traditional faldstool structure, its by the seat 1 of two activities with intersect the bracing frame 2 that the pole 21 that articulates forms by two groups and form.

Each seat 1 is made up of batten 12, be individually fixed on two crossbeams 11, and an end of crossbeam 11 is articulated in the top of two groups of poles 21 of bracing frame 2 respectively.

The bottom of two chair back rods 3 is the outsides that are articulated in seat 1 two crossbeams 11 in the outer part, is connected with backrest face 32 above two chair back rods 3, also is connected with connecting plate 33 below two chair back rods 3; Width at the seat batten 12 at the rear of seat 1 and two chair back rods, 2 articulated sections is greater than the distance between two chair back rods 3 in addition, and identical with the width of backrest face 32 and connecting plate 33.

Key of the present utility model is: two chair back rods 3 are provided with one spacing " L " type pin 5 below this articulated section, or fix a bracing piece 6 above this articulated section at the rear of two chair back rods 3.

As Fig. 4, shown in the 4A, when multifunction chair is realized the function of its chair, making chair back rod 3 and seat 1 be an elevation angle places, because spacing " L " type pin 4 on two chair back rods 3 can support on the pole 21 of bracing frame 2, be greater than the distance between two chair back rods 3 because of width again simultaneously at the seat batten 12 at the rear of seat 1 and two chair back rods, 2 articulated sections, and the termination that a bracing piece 6 is fixed at the rear of two chair back rods 3 also can support on this seat batten 12, at this under the two simultaneously spacing effect (satisfying a condition gets final product), the elevation angle maximum of chair back rod 3 is limited, realizes the function of back with this.

As shown in Figure 5, when multifunction chair is realized the function of desk, because two chair back rods 3 concern with the pivot joint of the crossbeam 11 of seat 1, when making it be parallel placement with the crossbeam 11 of seat 1, because the width at the seat batten 12 at the rear of seat 1 and two chair back rods, 2 articulated sections is greater than the distance between two chair back rods 3, then 12 pairs two chair back rods 3 of this seat batten have the position-limiting action of other direction again, and backrest face 32 and connecting plate 33 can be stitched together with seat 1, the outside two crossbeams 11 of seat 1 are provided with the keeper 4 that positioning chair leans against bar 2 simultaneously, and form a larger area desktop, this moment, the fixing bracing piece 6 in rear of two chair back rods 3 can replenish the height on desktop both sides, made desktop have more associative perception.

As shown in Figure 6, because the pivot joint relation of the crossbeam 11 of seat 1 and bracing frame 2, chair back rod 3 concerns that with the pivot joint of crossbeam 11 then this multifunction relaxing chair can fold easily.
